Digital Fortress Chapter 13

Tokugen Numataka stood in his plush, penthouse office and gazed out at the Tokyo skyline. His employees and competitors knew him a sakuta same-the deadly shark. For three decade she'd outguessed, outbid, and out advertised all the Japanese competition; now he was on the brink of becoming a giant in the world market as well. He was about to close the biggest deal of his life-a deal that would make his Numatech Corp. the Microsoft of the future. His blood was alive with the cool rush of adrenaline. Business was war-and war was exciting. Although Tokugen Numataka had been suspicious when the call had come three days ago, he now knew the truth. He was blessed with myouri-good fortune. The gods had chosen him. â€Å"I have a copy of the Digital Fortress pass-key,† the American accent had said. â€Å"Would you like to buy it?† Numataka had almost laughed aloud. He knew it was a ploy. Numatech Corp. had bid generously for Ensei Tankado's new algorithm, and now one of Numatech's competitors was playing games, trying to find out the amount of the bid. â€Å"You have the pass-key?† Numataka feigned interest. â€Å"I do. My name is North Dakota.† Numataka stifled a laugh. Everyone knew about North Dakota. Tankado had told the press about his secret partner. It had been a wise move on Tankado's part to have a partner; even in Japan, business practices had become dishonorable. Ensei Tankado was not safe. But one false move by an overeager firm, and the pass-key would be published; every software firm on the market would suffer. Numataka took a long pull on his Umami cigar and played along with the caller's pathetic charade. â€Å"So you're selling your pass-key? Interesting. How does Ensei Tankado feel about this?† â€Å"I have no allegiance to Mr. Tankado. Mr. Tankado was foolish to trust me. The pass-key is worth hundreds of times what he is paying me to handle it for him.† â€Å"I'm sorry,† Numataka said. â€Å"Your pass-key alone is worth nothing to me. When Tankado finds out what you've done, he will simply publish his copy, and the market will be flooded.† â€Å"You will receive both pass-keys,† the voice said. â€Å"Mr. Tankado's and mine.† Numataka covered the receiver and laughed aloud. He couldn't help asking. â€Å"How much are you asking for both keys?† â€Å"Twenty million U.S. dollars.† Twenty million was almost exactly what Numataka had bid. â€Å"Twenty million?† He gasped in mock horror. â€Å"That's outrageous!† â€Å"I've seen the algorithm. I assure you it's well worth it.† No shit, thought Numataka. It's worth ten times that. â€Å"Unfortunately,† he said, tiring of the game, â€Å"we both know Mr. Tankado would never stand for this. Think of the legal repercussions.† The caller paused ominously. â€Å"What if Mr. Tankado were no longer a factor?† Numataka wanted to laugh, but he noted an odd determination in the voice. â€Å"If Tankado were no longer a factor?† Numataka considered it. â€Å"Then you and I would have a deal.† â€Å"I'll be in touch,† the voice said. The line went dead.

Emma and Clueless

Transformations often involve familiar themes but reflect those themes in a different context in order to resonate the values and interests of that society. Thus, context dictates form and meaning as well as the values inherent in the texts. Amy Heckerling’s, 20th century American film, Clueless is a transformation of Jane Austen’s conservative Regency England, Emma. The use of different techniques and medium allow Emma’s themes of personal growth, social structure and the role of women in society to be conveyed in a more appropriate form in Clueless.The main characters, Emma and Cher are representational products of their society and parallels can be drawn in the opening scenes, particularly in relation to self-knowledge. The Bildungsroman progression from delusion to social awareness is a universal value in both texts despite their differing contexts. Emma is introduced as â€Å"handsome, clever, and rich† who had â€Å"a disposition to think a little t oo well of herself. † Austen’s satirical tone as the omniscient narrator alerts the responder to Emma’s inability to understand her position in society. Furthermore, while Emma successfully matches Mr. Weston and Ms.Taylor, her motives are superficial as she sees it as â€Å"the greatest amusement in the world! † She also believes Harriet’s beauty â€Å"should not be wasted on the inferior society†, and it would be â€Å"interesting and highly becoming† to â€Å"improve her†. Austen employs verbal irony through Emma’s dialogue, which exposes her flaws of arrogance and shallowness. However, Emma eventually develops self awareness as shown when she realizes her mistake of matching Harriet with Mr. Elton and influencing her to refuse a suitable marriage with Mr. Martin. There is a similar character development in Cher despite the difference in context.Heckerling implements voice overs to create an immediate sense of irony wh en Cher’s â€Å"way normal life for a teenage girl† is juxtaposed with a dolly-tracking shot of her choosing outfits from a computer operated wardrobe in a grand bedroom. In doing so, Heckerling continues Austen’s satirical mode by highlighting Cher’s lack of social awareness. This is further reinforced through her dialogue, â€Å"I have direction†¦towards the mall† and Dionne’s statement, â€Å"Cher’s main thrill in life is a make-over†¦it gives her a sense of control in a world full of chaos†, which imply her superficial obsession with image and materialistic values.Cher’s final ability to see beyond the superficial and realize her mistakes â€Å"I was just totally clueless† is parallel to Emma’s reconciliation to society and its values. Similar to Austen, Heckerling reflects values that are consistent with any age and time- the absolute necessity for young people to gain social awareness. Socia l hierarchy in Regency England was permanent and immobile. It was governed by strict rules of adherence to rank and place, and was determined by birthright and inheritance. Miss.Churchill and Captain Weston’s marriage challenged the social hierarchy due to a large social imbalance in their marriage, and through authorial intrusion, it was deemed â€Å"an unsuitable connection and did not produce much happiness. † Austen demonstrates the virtually impermeable social structure through her criticism of the Coles and that †it was not for them to arrange the terms on which the superior families would visit them†, indicating that money gained through trade and not birthright, doesn’t indicate status.Emma’s high modality and contemptuous tone employed when she claims â€Å"the yeomanry are precisely the order of people with whom I feel I can have nothing to do† further highlights the inflexibility on class interactions. Finally, Harrietâ€℠¢s marriage to Mr. Martin, a farmer, results in the loss of friendship between Emma and Harriet as stated by Austen’s authorial intrusion, â€Å"the intimacy between her and Emma must sink. † This epitomizes the clear demarcation of status and that Emma shouldn’t associate with Harriet due to their differing social status. Cher’s world also has a class structure that underpins her society.This idea is explored through the camera panning out to take long shots of the rigid societal tiers, whilst Cher introduces Tai to the stratified social groups at school including the â€Å"Persia mafia†, the crew and the â€Å"loadies†. Elton’s indignant tone conveys class consciousness in his rhetorical questions towards Cher as she suggests Tai as a romantic partner, â€Å"Why Tai?! Do you know who my father is? † Later, Cher is abandoned in a carpark by Elton, and the far shot of a blinking neon sign of a clown symbolizes society’s mockery of her attempt to undermine a defined system of class.Clearly, class consciousness pervades both societies, especially in selecting romantic partners. Regency England dictated the position of women in society by strict codes of conduct. Primarily, women of Emma’s class were constrained by society’s expectations of a match within their social class. Captain Weston’s marriage to Miss. Churchill is juxtaposed to Miss. Taylor’s, thus allowing Austen to comment on the female and male positions in society, in that women are meant to be passive and have less say in their marriage. According to Mr.Weston’s idea, â€Å"it’s being a great deal better to chuse than to be chosen, to excite gratitude than to feel it†, hence demonstrating the double moral standard prevalent in society. Furthermore, Emma’s sister, Isabella, is married to John Weston, and through authorial intrusion, Austen comments that â€Å"Isabella always thinks a s he does† demonstrating a women’s duty as a wife. The use of dialogue in Mr. Knightley’s warning to Emma, â€Å"Men of family would not be very fond of connecting themselves with a girl of such obscurity†¦[Harriet]†, exemplifies society’s expectation of women to interact within their own social class.On the other hand, Clueless doesn’t offer the restricted patriarchal world of Austen as young women could be independent, outspoken and have many more choices, including marriage. The focus of the medium shot on Cher as she struts down the schoolyard in her vibrant yellow costuming portrays her outgoing attitude. The eye contact of male passerbys creates vectors and the comment â€Å"As if! † highlight Cher’s disgust at their attention, exemplifying women’s freedom to choose their romantic partners. This idea is reinforced by Cher’s comment on Dionne’s relationship, â€Å"Dee, you could do so much better. Contrary to Austen, Heckerling recognizes the change in the position of women in society in that they have more freedom in their social behavior and relationships. In conclusion, Emma and Clueless offer profound and satirical insights into their respective contexts. While the need for social stability and the need for young people to gain social awareness, remain unchanged, but the position of women in society has shifted dramatically. Such ideas are reinforced by the different mediums, both of which effectively reflect the themes and values of that context.

Analyse How an Adaptation of Your Choice Deals with Gender - Catwoman Essay Example for Free

Analyse How an Adaptation of Your Choice Deals with Gender – Catwoman Essay The representation of female super heroes in the media can be said to have had huge institutional, political and social influences that would suggest those in power are favoured at the expense of those without. Female super heroes tend to promote sexualisation and stereotypical gender roles of women, throughout comic books and super hero movies, but why? In this essay I will look at the character of Catwoman, and her representation as a female, particularly in the 2004 adaptation film â€Å"Catwoman†. Originally, she is an iconic character in the batman series. Created in 1940 by Bob Kane (batman creator) and Bill Finger, she has had a strong presence in batman comics and adaptations since then. Her role as a mysterious burglar and jewel thief led her to just miss out on a place in the top ten, ranking 11th in IGN’s ‘Top 100 comic book Villains of all time’ (2009) and 51st in Wizard magazines ‘100 greatest villains of all time’ list (2006). The character has been used in hundreds of comic books, as well as video games, radio stations, TV series, animated series and films. Although she is featured in mostly batman productions and texts, Catwoman was given her first comic book series in 1993, written mostly by Jim Balent. Several years down the line, Catwoman stared as the lead role in the feature film, made in 2004. The movie was an example of post feminism at its best, as in the 1970’s, only 15% of action adventure movies cast female leads. The movie was directed by Pitof and was released on July 23 by Warner Bros. and Village Roadshow Pictures. The cast members include Halle Berry, who plays Catwoman, Benjamin Bratt, Sharon Stone and Frances Conroy. I have chosen to analyse this movie because females are not usually given dominant roles in superhero movies, especially as the lead character. There are many stereotypes that surround women, and I believe this movie challenges those. The film was inspired by the DC comics villain of the same name, however stars a new character, Patience Phillips. There are several similarities to the original character. For example, she has similar office job and is killed by someone she works for. In the 1992 movie staring Michelle Pfeiffer, she uncovers a dark secret in the company and is thrown to her death from a great height. The plot for the more recent movie is very like its predecessor. In both versions she is brought back to life by a group of wild cats. However the most relevant similarity is her appearance and costume. Throughout the film, Catwoman is dressed in a tight black latex costume, black connoting mystery and evil. This material is often associated with sexuality; it clings to her body and shows off her curves. Over the years her costumes have become even more provocative, with this Catwoman being more fetish than ever. These clothes represent Catwoman as a sexual image to be looked at by the opposite sex. Laura Mulvey describes this as the Male Gaze. She explains â€Å"In their traditional exhibitionist role, women are simultaneously looked at and displayed with their appearance, coded for strong visual and erotic impact so it can be said to connote to-be-looked-at-ness. † (1975, p33). It is arguable that woman in the genre of action, drama and super hero are not represented as women, rather an object of sexual desire. The women featured in such genres are slim, pretty, and all wear tight clothing. Lillian Robinson refers to woman super heroes as a pin up girl in a cape, rather than genuine characters (2006). The skimpy outfit has great erotic significance (Richard Reynolds 1994) and could create a negative portrayal of females, as well as being a very bad influence for the young women and girls who watch the movie, or read the comics. Clearly, the media heavily influences teenagers already. They follow the latest fashion trends from celebrities, coolest haircuts, and they diet and loose weight to look like the people they see on TV and in magazines. They look up to the people in the media, and the image of Halle Berry in the cat suit, may encourage young girls to objectify themselves in a similar way. Already, Playboy as a brand has become a fashionable thing, for young girls even at the age of 8. They have the playboy bunny pencil cases, posters and duvet covers. Just like this, cat woman may encourage youthful girls to dress inappropriately with increased sexuality. Even Catwoman’s make-up connotes sexualisation. Her lips are painted scarlet red, which draws your attention straight to her mouth, as well as being the colour of lust to stimulate sexual arousal. This idea is due to the fact men and women have more blood flowing through their lips whilst aroused, turning them a darker shade. Halle Berry was most likely cast because of her beauty. Her eyes, lips, body and sex appeal come before everything else in the movie, (Roger Ebert, 2006). The director of this movie has chosen to portray her as an object of sexual desire for men, rather than a role model for the power and liberation of women. Typical of Hollywood movies, the overtly sexualised view of women is rooted in the darkest chamber of male desire, (Kevin Maher, 2005). She appears powerful and dominant, however, she is in fact the opposite, and inferior to the gaze of men. Laura Mulvey says in her book Visual Pleasure and Narrative Cinema, â€Å"Women as image, men as bearer of the look†, (1975). Personally this idea is predictable and brings nothing new to the genre. Wonder Woman first appeared on screen wearing a gold bra and blue knickers, and in those 36 years gone by, you have to ask yourself, why do superheroes need to be dressed so provocatively? Why can’t the action hero fight crime and ‘kick ass’ in a baggy jumper and a pair of dungarees? Kevin Maher, 2005). I believe the reason behind this is due to the fact that the representation of characters such as Catwoman and Wonder Woman where created by those with power over women. The institution DC comics created both in the 1940’s, which was largely if not entirely controlled by men. Women had no control over their creation and as powerful as Catwoman may be, she is still just an image of the male gaze. Created in a time where females had no authority, they where not able to argue against what could be considered as an unfair representation. Angelia McRobbie has a theory in defence of this sexualised representation, and believes men did not create this image. Women have gained the equality they where fighting for, and now they are using their assets to their advantages. In this case, Catwoman is willingly showing of her body to attract the male gaze, because it gives her power over men. She summarises that post feminism positively draws on and invokes feminism, (1994). However it’s not all negative, Over time things have changed, the presence of female leads in the super hero genre has increased, and to an extent therefore, time has favoured the female lead. Some 50 years ago, males where seen as the hero, there to protect the fragile women. Superman and Lois Lane are a classic example of where the lead role is given to a man, he is strong and courageous, while Lois is inferior to him, she has no special abilities and relies on him completely. However, the number of women in this genre proves a success for the feminist woman and an improvement in today’s society. Iconic actresses such as Angelina Jolie and Uma Thurman have stared as the female lead in modern action movies. Lara Croft, Tomb Raider and Kill Bill are both examples of woman taking active roles, and how accepting it is in this particular genre. Jolie also stared in Mr and Mrs Smith, which showed her as an equal to her husband, just as strong and just as capable of fulfilling the dominant lead. Catwoman has evolved over time, first known as The Cat in DC comics; she then progressed onto TV screens. Her sexual appearance made her an object of desire to the eyes of the male audience, and a role model to girls who wanted to be her, Suzan Colon (2004). In the Halle Berry adaptation, Catwoman is reborn a new woman, sleek, sexy, ambitious and not held back by the restraints of society. She is rebellious and follows her own desires as a feline crime fighter. This representation of Catwoman forces the question that perhaps contemporary women are constrained by the rules of society and are not free. Catwoman challenges the female stereotype and adopts the masculine lead role in this superhero movie. She is a protagonist, independent and capable of standing alone. A crucial scene in the movie shows Catwoman arguing with a large masculine looking man. She demands he turn down his music, which results in her physically attacking him. The argument ends with him lying on the floor with her foot on top of him. This scene portrays her as superior to the man, and the physical pose makes him vulnerable to her. This scene is important, because when she was her human self, known as Patience, the man would not listen to her. As Catwoman, her voice is heard. Simone de Beauvior Invokes ‘the independent women’ who wants to be active, wants to take things for themselves and refuses the passivity men try and want to impose on her. The modern woman accepts masculine values; she prides herself on thinking, getting a job and working to pay her own way, existing on the same terms as man, (1949). Catwoman does exactly that. She completely demolishes feminine stereotypes at the end of the movie when she rejects the love interest and chooses to be a free independent woman. She is not reliant on anyone, especially a man and because of that, I believe this movie demonstrates a victory for women. â€Å"Freedom is power† (Catwoman, 2004). Motivated by revenge, no man stands in her way. However another scene tells a very different story and shows off Catwoman as purely a vision of sexual desire. As she is transformed from patience Phillips, into Catwoman, supposedly now free and independent, we are reminded of her physical qualities. ‘Reminded’ is an understatement actually; it’s thrown in our faces. As she walks across a rooftop the camera angle starts from her feet, moves up her legs and to the top of her body. Paying particular attention to her bum, first impressions are everything! This scene completely confirms Mulvey’s theory, and as Liz Wells suggests, certain films objectify the female star, (2004). However Catwoman is not the only dominant female in this movie. Hedare Beauty is the company Patience works for, and is run by a man named George, or so you are made to believe. Yet in fact, the one calling all the shots is his wife, Laurel. She is controlling the strings of her puppet husband and forces him to her way of thinking. She is an evil, sinister character, full of greed, and in the end she kills her husband in cold blood. She is the villain in this movie, but also a woman in power and free from the constraints of society. In the early 1970’s, after the second wave of feminism, more women were gaining better professions and breaking out of the stereotypical roles. The post modern figure of a female became more appealing to both genders, and resulted in women wanting to achieve higher status in the world of work. An example of such acceptance was seen in the recently released song by male pop artist Ne-Yo, called ‘Miss Independent’. This continues the suggestion of the need for change in the way female super heroes where represented in order to capture the post-modern audience. Catwoman and Laurel Hedare are both great examples of female presence in superhero movies and the result of female empowerment. Judith Butler brings an interesting theory to the table. She believes gender is free floating, rather than fixed, that males and females aren’t simply masculine and feminine. She says that gender is a performance, rather than an aspect of our identity and we behave differently on different occasions. This theory suggests Catwoman isn’t necessarily challenging gender roles by taking on the masculine super hero, but rather an act she’s choosing to play. Women can be masculine because the individual chooses their gender identity. â€Å"When the constructed status of gender is theorized as radically independent of sex, gender itself becomes a free floating artifice, with the consequence that man and masculine might just as easily signify a female body as a male one, and woman and feminine a male body as easily as a female one† (Judith Butler, 1990, p6). Interestingly she suggests that if there where no longer conventional roles for either gender it would be considered the norm for a woman to be in a position of power at work or for a man to stay at home looking after the children. After looking into the history of Catwoman, her creation, and other adaptations in the past, I believe her image is over sexualised. The film is centralised around a beautiful woman, wearing the sexy, tight black costume to do none other than attract male attention. They do however promote that she is a powerful woman and has the freedom to do as she pleases. The fact that a female is the lead role in a movie of this genre is a positive thing. Although the message left behind is that to have freedom and power, you have to entail being objectified. In the end, this movie has done the same as its predecessors, portray woman in a sexualised, unrealistic and in a possibly insulting way.

Tables' data analysis Essay Example | Topics and Well Written Essays - 1000 words

Tables' data analysis - Essay Example The sub-rows consist of the options for answers and the columns consist of the reasons for the answers. The items marked with an asterisk (*) represent those responses which are not only correct, but are explained rightly too. As in example 1, 70.5% of students selected the right answer and the right reason for their answer. All other values imply either a wrong answer, or the wrong reason, or both. The values in bold (in question 1, 14.1%) provide the percentage of students who answered wrongly and that percentage exceeds 10%. Jian Wang (2006) stated that the role of teachers is perceived as a very strong one in mentoring students. This would also involve a reform minded teaching that would have many challenges. According to experts in the field, a substantial set of these alternative conceptions, i.e., a wrong answer set of more than 10%, is considered a significant alternative conception (Chandra, 2005). These significant alternative conceptions require further study into them, as these are mistakes made by a significant group, pointing to weak basic concepts. If none of the wrong responses total more than 10%, there is no significant alternative conception, as in question 8. In some cases, when there is no response in a particular field, it is represented with a '-'. A surprising fact is that this quiz was taken by pre-service science teachers. Unfortunately, this shows us that even aspiring teachers are not always clear with their concepts, leading to the realization that "Teachers often subscribe to the same alternative conceptions as their students." as per a previous research, Alternative Conceptions, Concept Change, and Constructivism, These teachers, in turn would pass on the misconception, or alternate conception, to their students, causing a network of misinformed science students. These tables help professionals to avoid situations like those, by restricting the spread of these alternate conceptions. The above table gives us an insight into the percentage of students, who got the first part of the question right, but got the second part, the reason, wrong. As a multiple choice question always has the possibility of chance (33% in most of these questions), this table helps getting a finer look at how often chance comes into play here. Getting one answer out of three is much easier than getting one answer out of six options. This is made evident by the drastic difference in percentages between students getting only the first part right and those getting both right. Another important aspect of this table is that it helps realizing how many students truly understand the underlying concepts behind the questions. An answer can be answered with just a little knowledge, but actually explaining it poses a much bigger problem for students. There is an approximate average of 12% difference between the two percentages. This reflects not only chance, but also raw knowledge with a feeble conce ptual base. Certain questions, namely 11 and 15, have no difference in the two percentages. These imply specific knowledge required for the question, possessed only by those who got the answers right. But most of the questions show an opposite

Music Tastes - Assignment Example Did the musicians seem well prepared for the concert?)   ***Compare the pieces from this performance with other compositions you have studied in class, noting similarities and differences. (Note: In selecting a composition from class, you may want to look for a piece by the same composer, from the same style period, or of the same genre as the piece(s) from the performance.)   ***Describe the behavior of the performers and the audience. What, if any, interaction occurred between the two? What kind of behavioral expectations do performers and audiences bring to the concert? How are these expectations satisfied or frustrated?   On October 15, I attended a concert by the NDR Symphony Orchestra of Hamburg at the New Jersey Performing Arts Center. The performance consisted of only two pieces, yet both were met with enthusiastic applause and praise. †¨Ã‚   The first piece performed was the Violin Concerto in D major, Op. 35, by Piotr Ilyich Tchaikovsky, with the violinist Midori as the featured soloist. The piece was divided into three movements, the first being Allegro moderato. The Concerto opened with the orchestra playing a crescendo until the appearance of the soloist, who presented the principal themes. From this point, the texture varied between the monophony of the solo violin and the homophony heard from the full orchestra. The melody introduced by the violin was then repeated in various instruments with large contrasts in dynamics and tempo, although the predominating tempo was allegro. When the solo violin returned it was accompanied by the other violins playing a background of staccato notes. The high point of the first movement occurred when the solo violin produced an extremely high pitch in pianissimo and slowed down to a static pace, demonstrating her ability on the instrument. This movement ended with the entire orches tra playing fortissimo with a strong beat.

Global Warming - Case Study Example Still, it is even more ironic to acknowledge that though global warming is closely linked to Industrial Revolution, which added to human affluence, yet, global warming is surely poised to wrench out a heavy economic cost from both the developed and developing economies. The sad thing is that if one takes into consideration the places worst impacted by global warming, one realizes that it is the poorest and least developed of nations like Bangladesh, Myanmar, Honduras, Vietnam, Nicaragua, etc that are to bear the brunt of this imminent calamity of human making. Global warming is ravaging the developing world in the form of natural disasters like droughts and floods and the consequent epidemics, hunger and large scale human migration and poverty. The thing that needs to be feared is that such calamities and disasters are bound to get more pervasive and pan-global, if something is not urgently done to ameliorate the situation.

Choose a business whose main focus is in the manufacture of renewable Essay

Choose a business whose main focus is in the manufacture of renewable energy technology - Essay Example Aelos Wind Turbine Company may undertake strategic decisions such as defining the objective and policies of the company. Executives of the company are relegated with the task of analysing new markets and consequently designing new marketing strategies (Panneersalvam, 2006, p.2). They acknowledged the increasing demand in the wind energy industry; thus, they decided to offer their products to different countries. In addition, they have created alternative approaches to manufacturing. These executives established a long-term strategy that ensures sufficient financing. They focused on improving the technical features of the product. Lastly, executives at Aelos Wind Turbine Company designed strategies for recruitment, training, benefits, and salary. These are considered as strategic decisions as it determines the purpose, goal, and direction of the business organization (Panneersalvam, 2006, p.2). Meanwhile, tactical decisions are performed at the middle management level. Tactical decisions of Aelos Wind Turbine Company may include determining a suitable plant location, new product establishment, monitoring of budget, and acquisition of resources. Executives compare the overall performance of the company to the standard marketing plan. They analyzed summary reports that compare standard performance or overall plan for productions (Panneersalvam, 2006, p.2). In addition, they are concerned with information on actual versus the budgeted cost of error rates and processing accounting data. Lastly, these executives concentrate in variance analysis of firing and hiring, cost of training, and cost of recruitment (Panneersalvam, 2006, p.2). These decisions can be considered as tactical as those only affect a single department in the company. These decisions are frequently made by middle managers, which include heads of the departments (Panneersalam, 2006, p.2). Lastly, operational decisions are undertaken on the bottom management level. The operational decisions

Similarities and Differences in Mitosis and Meiosis Essay

Similarities and Differences in Mitosis and Meiosis - Essay Example Mitosis comprises of standard steps of Interphase, Prophase, Prometaphase, Anaphase and Telophase. Interphase is the process where cell prepares material for cell division. In this phase chromosomes are unseen, but chromatin granules are seen clearly.(Lehninger, 2008) In the Prophase in mitosis, four chromatids combine to form a pair of chromosomes which are joined by a centromere. Comparatively in Meiosis Prophase I, four chromosomes instead of chromatids combine to form two tetrads. The chromosomes in the tetrad cross over each other, allowing them to exchange genetic material. In the Metaphase in Mitosis, the two chromosomes line up in the center and split up into four chromatids which move to both of the poles. In Parallel, in meiosis, the two tetrads line up in the center and split up into four chromosomes which go to both poles. In the Telophase, all the material that has migrated to the poles gets enclosed by the nuclear envelope in Mitosis as well as meiosis. Mitosis is compl eted at this stage. Meiosis then proceeds to Meiosis II which is identical to mitosis. DNA replication is skipped in interphase and the cells proceed to divide exactly by the mechanism of mitosis. Thus mitosis involves a single nuclear division which gives rise to two identical daughter nuclei. Meiosis on the other hand involves two successive nuclear divisions and hence one diploid cell gives rise to four haploid cells. Consequently for mitosis to occur, the mother cell can be either haploid or diploid. However for meiosis to occur the mother cell has to be necessary diploid so that the chromosome number can be halved. Mitosis generally occurs in all somatic cells of the body whereas meiosis occurs only in the sex cells in the body. The number of chromosomes per nucleus remains the same after division i.e n remains n and same applies for 2n. The meiotic products contain a haploid (n) number of chromosomes, in contrast to the 2n mother cell. Mitosis is preceded by an S-phase in which the amount of DNA is duplicated. Only meiosis I is preceded by an S-phase. (Radboud University, 2003) Meiosis II proceeds without a pre S phase. Homologous chromosomes remain independent in mitosi s. On the other hand complete

Historiography Paper II Essay Example | Topics and Well Written Essays - 750 words

Historiography Paper II - Essay Example Following the end of World War Two, the US still faced a real threat from the USSR; this is where the foreign policy came in. Leading US politicians, statesmen and agencies designed a foreign policy that would cushion the country from negative ramifications brought about by its rapid rise as a global power. Specifically, the policy aimed at winning as many â€Å"friends† as possible and alienating hard-line anti-American nations. The Good Neighbor Policy, which the United States employed in its dealings with Latin American countries2. This policy was the embodiment of the objective of US policy at that time: to stem negative historical reactions to American interventions and promote cohesion between the United States and other countries. Over the course of global war, American policy went from benevolence (through grants and loans) and mild aggression to open intimidation and â€Å"bullying.† As it amassed more power, the US discarded the good neighbor approach in Latin America and engaged in explicit and blatant acts of aggression by sponsoring coups and armed rebellions in Latin American countries like Nicaragua, Panama, Chile, and Cuba. US policy went from maintaining world peace through peaceful interventions to sparking conflicts using armed interventions that embodi ed the â€Å"new† America3. Domestic influences had a significant influence on US international policy. Isolationist factions maintained that countries and regimes that openly and strongly opposed US policy should be maligned and marooned so that they would adhere to the ‘rules.† It is during this time that the United States started employing sanctions as a tool for exercising its military and economic influence4. It is safe to say that isolationist views were the architects of America’s high affinity for sanctions from the 1960s onwards. The international views held that America should embrace all countries regardless of their affiliations and ideologies. The

The Religion of Paul the Apostle by John Ashton Essay Example for Free

The Religion of Paul the Apostle by John Ashton Essay This book is the outcome of the author’s conviction that an important way of understanding Saint Paul has been neglected. He mentions the idea expressed in 1888 by Hermann Gunkel, that Paul’s life experiences are the key to understanding his teaching about the spirit. On page 198 Ashton quotes Heinrich Weinel as saying :-   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Whenever the early church speaks of spirit and spirits it is always a matter of a perception based on frequent occurrences of real experiences. We see therefore that this book is much more an attempt to explain Paul’s experiences than yet another examination of his theology. The blurb on the back of this unusual book says in the author’s own words :- Paul did, I think, found a religion, and this book is largely concerned   with the question of how he came to do so. Besides being a study of comparative religion it is also proffered as a contribution towards the   history of early Christianity. Some would argue with that definition – it seems to remove Christ from the picture and also the work of other evangelists. Paul has such a prominent position in the New Testament not necessarily because he was more important than other evangelists, but because, in Luke, he had such an excellent biographer. A look at the Bible references in the back of the book reveals how many times Paul’s life or words are referenced in comparison to the relatively few references taken from the gospels and the Old Testament. The book is very concerned with definitions, in particular with the difference between   religion – defined as experience, and theology – defined as the thinking that comes as a result of that experience. This is a scholarly work as can be seen immediately from the background of the author and the number of works by other scholars that he has consulted .John Ashton was formerly a lecturer in New Testament Studies at Oxford University. He had previously taught at the universities of London, St Andrews and Edinburgh. At the time of writing this book ( 2000) he was Emeritus Fellow of Wolfson College, also in Oxford. He is best known for writing about John’s gospel – ‘Understanding the Fourth Gospel’, ‘Approaches to the Fourth Gospel’ etc ‘The religion of Saint Paul the Apostle’ was originally a series of 8 lectures which the author had been asked to give at Oxford University in 1998. These were the annual ‘Wilde Lectures in Natural and Comparative Religion’, founded under a trust deed in 1908. The nature of the lectures has changed over the years   as Ashton explains. Once upon a time they sought to distinguish the higher religions from the lower, but this second part of the description was dropped in 1969, probably in an attempt not to appear racist or judgmental. He uses material both from Paul himself, but also from contemporaries of his from both Jewish and Hellenistic, i.e. pagan, backgrounds. Ashton describes how from the 1880’s onwards there had been attempts to study the New Testament as objectively as one might study any other historical sources, but also goes on to say that the people were concerned were actually theologians rather than historians and were in the main Christians. It is however a subject t upon which it is very difficult to remain objective whatever one’s background as believer, atheist, agnostic or member of another religion.   Ashton’s main argument in this work is that Paul’s personal mystical experiences, especially the events on the Damascus road recorded by Luke in Acts 9, may be of more importance than the somewhat unsystematic theology of his letters. The book seeks to show how important aspects of Paul’s life and ministry should be seen in the light of his religious experience. He quotes Schweitzer who said of Paul’s mysticism that it ‘marks the last stage of the battle fought by the idea of resurrection to establish its place in eschatology’. He examines closely what he sees as shamanistic elements of Paul, both in his teaching and his letters and mentions how, from the1880’s onwards there have been those who have sought to prove that Paul was greatly influenced by pagan mystery religions which abounded at the time giving as an example his theology of baptism which it could be argued was very similar to that of the re-enactions of the death and rebirth of various gods such as Attis,   a Phrygian god of vegetation and Adonis,   a Greek deity. These ideas would be familiar to Paul, bought up as he was in a world where Greek influence was important, but his main influence   must have been his Jewish background, although Ashton believes that Paul’s religion was rather more than a mere modification of Judaism. On page 135 Ashton describes baptism as practised in the churches that Paul founded as being no more than a token when compared to the rites of passage practised in other religions of the time. Some would disagree with this minimalisation of what they see as an important part of Christian ritual, and in many churches it is only undertaken after a period of instruction which may be quite prolonged. Ashton says that the starting point for Paul’s thinking on the subject comes not from his knowledge of baptismal practices in Judaism, but was a result of his dramatic death life experience on the Damascus road and the subsequent resurrection to a new life in Damascus.   In chapter 7 he explains the part that the spirit world played in ancient times – anything that could not be explained was deemed to be the work of spirits and gods – for good or ill. Mention is made of how demons were believed to be behind and to explain all sorts of happenings that deviated from the norm such as storms, plagues, riots, unhappy love affairs and much more. Paul does not mention demons much, though he does refer to what he sees as his one great adversary – Satan. Ashton explains the role of the spirit both in Paul’s life and in that of his converts. He also examines the role of Christ himself in a passage which he realises may cause offence as it is entitled ‘Jesus the Shaman’.   In order to mitigate any offence he states that shamanism was not the most important aspect of Jesus’ ministry, but says that Jesus’ life as a wandering healer fits in with shamanistic practices even more than does the work of Paul. He claims that Jesus was not unique in this quoting several sources. There is detailed reference to the various words used to describe Jesus’ actions in ‘muzzling’ evil spirits. This, Ashton says, merely places Christ alongside other exorcists of the time. The difference was how he did it according to Mark chapter 3 v 11 and 12 where we are told that â€Å" Whenever the evil spirits saw him they fell down before him and cried out ‘You are the Son of God’.† On page 69, still discussing the shamanism of Christ, Ashton reminds us that in all three synoptic gospels the two incidents of the baptism of Christ and the temptation in the wilderness are recorded in that order and   he admits that for the purposes of his argument it would be better if they had been   recorded in the reverse order which would have fitted in better with the usual shamanistic experience of struggle followed by call or empowerment but a t least the two are associated.   Although in chapter 2, entitled ‘Paul the Enigma’ the question is asked ‘Was Paul a shaman?’ the answer is quickly given ‘Not really’. A shaman is a member of a tribal society who acts as a medium between the natural world and the spiritual one. A shaman is limited in his influence and also his periods of spirit filled ecstasy are limited and transitory. He uses magic to control events in the natural world, whether for good as in healing, or for bad as in curses. Paul did use his powers to control nature as when on the isle of Malta ( Acts 27) to cure many people, but it was available widely and not used in a negative way. Yet the author insists that some of Paul’s practices were shamanistic in nature and quotes the example of a picture of Paul struck blind from ‘Trà ¨s Riches Heures du Duc de Berry.’ Under the picture are the words ‘The inspired priest or shaman is usually called to his vocation   by a traumatic experience.’ Ashton sees the role of the shaman in two parts – the shaman’s personal experience and his ability to persuade other people of his exceptional gifts. This latter aspect is described as the social aspect. Ashton quotes at length from a Japanese work on the subject which states that a shaman is one who receives a gift from the spirit world. Usually this is from one spirit who becomes a companion or guide and after receiving the gift the shaman may experience a period of hysteria afterwards which results in illness. The process involves a complete change of character, perhaps like that described at the time of Paul’s meeting with the risen Christ. Whatever happened to Paul he himself saw it as a vision and a call – see Galatians 1. On page 243 Ashton mentions the finding of the documents now known as the Dead Sea Scrolls in 1947. One of these ‘Songs of the Sabbath Sacrifice’ was finally published only in 1985. He states that as early as 1971 John Bowker had put forward the proposition that Paul’s vision took place while he was engaged in a period of merkabah mysticism as mentioned in the scroll. He then mentions the doctoral thesis published in 1980 by Seyoon Kim ‘The Origin’s of Paul’s Gospel† which seems able to prove a link between Ezekiel 1, a key passage in the study of such mystic practises, and the verse in the Second letter to the Corinthians   ( 4 v 6) where it says ‘For God who said â€Å"Let light shine out of darkness† made his light shine in our hearts’. Ashton further argues that Paul’s ability to discuss spiritual matters is important in understanding the continuing popularity of his writings. The aim is to define Paul – a convert, a prophet, a mystic, an apostle, a charismatic, a shaman. Whichever definition one prefers Ashton argues that Paul acted as he did because of the set of circumstances in which he found himself. In chapter 4, entitled ‘Paul the Mystic’ Ashton is concerned with Paul’s mystical experiences, especially the rapture which he described in 2 Corinthian 12 as being carried up to the third heaven. The trances in which visions like these occur were well known in Judaism, but as Ashton points out, are a feature of shamanistic activities throughout the world. Despite this Ashton admits on his final page that any observable resemblances between Paul’s life and features of shamanism are coincidence only. Another aspect of the book is the examination of why, according to Ashton, Paul generally seemed to prefer to speak to Gentile audiences rather than the Jews of whom he was one, and, alongside this, there is an examination of Paul’s attitude to traditional Judaism, which it is possible he never officially renounced. See 2nd Corinthians 11 v 22 ‘Are they Hebrew? So am I’   Ã‚  Ashton seems fascinated with the idea of the symbiosis of Judaism and its younger offspring Christianity as when Paul spent three weeks at Thessalonica explaining how Jesus had to die and rise again, using the Jewish scriptures to do so.( Acts 17 v 1-4). Christians today read Paul’s words after 2000 years of the church developing his ideas into what we call Christian theology, something that was not in place before Paul – says Ashton, but he pays little attention to the theology of Christ found in the gospels. Ashton believed that Paul was a religious thinker in the sense that his thoughts were reflection upon his experiences rather than a pure theologian. In his introduction Ashton discusses various previous ways of looking at Paul and his influence i.e. a studies of his conversion and subsequent work in founding and building Christian communities; those who aim to present a systematic account of his thinking; Paul’s psychology and finally those who seek to put his work in a historical or/and sociological perspective. He concludes that none of these approaches quite fits his purpose, without stating precisely what his purpose is at this point. Chapter 2 describes Paul as an enigma – a puzzle. He questions how much shamanistic practices, already present in Judaism back until the time of the Judges, affected Paul. Ashton quotes passages from I Samuel describing prophets and seers, a translation which Ashton believes to be wrong. and quotes much later passages, in Isaiah and Jeremiah where the practices of mediums and so on were condemned e.g. Isaiah 8 v 19. Like many others of Christ’s followers Paul was an exorcist and a prophet. On page 36 Ashton concludes that there is no evidence that Paul picked up shamanistic practices from another   shaman, unless, as some such as Andrew Wilson believe, he did meet Christ in life and copied his practices. Among the many works quoted is Karl Barth’s commentary on Romans in which Ashton says that Barth deplores any attempt to describe Paul as a religious figure. Also mentioned is   J. Louis Martyn who aims in his commentary to dispel the idea that Paul was in any way anti-Jewish. Barth in particular splits religion absolutely from theology, but although it is possible to study the subject in a totally objective way, just as one might study chemistry, I do not feel that this is true of Paul. His theology sprang very definitely from his personal experience of the Saviour and the Holy Spirit working within him. Ashton also tries to explain the huge success of Paul’s message in bringing about change in the lives of both individual’s and communities. On page 234, in a chapter entitled ‘Paul the Possessed’ Ashton quotes Paul’s words in his letter to the Galatian church , Galatians 4   v14, where he describes how, despite his physical difficulties, he was welcomed ‘as if I were an angel of God’ i.e. as a messenger directly from God.   George Bertram is quoted as saying that this passage is the key to Paul’s own understanding of his role.    ‘He is entitled   to speak in this way’ says Bertram , ‘because Christ is manifested in him, in his body, in his missionary work’. On page 236 Evans-Pritchard’s statement about how, when a man is seized by a spirit, the event may be a temporary one, is quoted. Evans-Pritchard went on to say that if it is a permanent possession, the person becomes a prophet capable of healing, of exorcism and having foresight into events. The presence of the Holy Spirit was the ruling factor in Paul’s life. Consider for instance his words in Romans 8 v 14 -16:-‘Those who are led by the Spirit of God are the sons of God ‘ and ‘the Spirit itself testifies with our spirit that we are God’s children’. Yet this is the same Paul who described himself in 1st Timothy as ‘the worst of sinners.’ (I Tim. 1 v 16). How great the change must have been. If we take Luke’s word in Acts 28 where he describes how Paul, right up until what may have been the end of his life, continued to teach and preach and quoted Isaiah who spoke about how the Holy Spirit spoke the truth, then in Paul’s case the change that occurred on the Damascus road was very permanent and influenced all that he both did and said.   Professor Ashton claims on page 162, in a chapter concerned with the apostleship of Paul, that Luke, as biographer, has no interest in the question that intrigues him. The story Luke is telling is that of how Christ, rejected by the Jews, was proclaimed to the Gentiles. Luke was eager to show how Paul used scripture to make his point. Ashton describes Paul, on page 162, as the chief witness and as such he was not reluctant to use spiritual power to do so.( I Corinthians 2 v 5) Just as Luke uses the phrase ‘in the power of the spirit’ to describe how Jesus returned to Galilee, Paul uses the same phrase to describe his own activity. Luke also tells us that Christ gave the apostles power and how Paul manifested similar power. Ashton mentions the passage in 2nd Corinthians 12 v 12 that he feels is the key to Paul’s ability to gain a hearing and also to convince –‘The things that mark an apostle – signs, wonders and miracles – were done among you with great perseverance.’ The people were convinced because his words had authority behind them – an authority he claimed came from the Messiah himself. Ashton mentions the work of Ramsey MacMullen in describing how religious fairs would convince people to join pagan religions. Their senses would be assaulted by all kinds of wonders. Ashton claims that Paul’s career begun in a similar way as a wonder worker and, although Luke tells us that Paul preached the word it seems likely that it was his spiritual acts that were the first attraction and only later did promises of salvation and forgiveness take root. Ashton concludes his unusual book by saying that he is a historian, and having looked at Paul using history and comparative anthropology as an alternative to the work of theologians, he hopes that if the book is noticed at all it will show that the way of the theologian is not the only way to come to an understanding of Paul the Apostle. This is not an easy book to either read or review. Not because it is difficult to follow the arguments, whether or not one agrees with them, but because it is so easy to get sidetracked along paths that one has not perhaps explored before such as the influence of Jewish mysticism on the early church or what other commentators say about a passage  Ã‚   such as that in Ezekiel chapter 1. Bu t if it rouses interest in this subject it has done its job even if the author is rather divident to whether or not or not he has proved his point.       Bibliography and Works Cited Ashton, John, Approaches to the Fourth Gospel ( Oxford University Press, Oxford 1994) Ashton, John, The Religion of Paul the Apostle ( Yale University Press, New Haven and London, 2000) Ashton, John, Understanding the Fourth Gospel (Clarendon Paperbacks, Oxford, 1994) Bertram,G. ,Paulus Christophoys:Ein anthropologisches Problem des Neuen Testaments in Stromata: Festgabe des akademischen Verreins zu Giessen im Schmalkaldener Kartell anlà ¤ÃƒÅ¸lich seines 50.

The Economy Of Delta State In Nigeria Economics Essay

The Economy Of Delta State In Nigeria Economics Essay Nigerian economy, at first was based mainly on agriculture; it exported agricultural products like cocoa, rubber, palm products, cotton, groundnut, hides and skin etcetera. But then oil was discovered in the south-south of Nigeria i.e. Rivers, Bayelsa, Edo and Niger Delta states, and agric production was abandoned. The essay question is What are the economic cost and benefits of oil industry in Delta, Nigeria? The objective of this essay is to find out what the economy cost and benefits of the oil industry in Delta state, Nigeria, and also I will examine just how the state has put up with the production of oil and also the effects i.e. the cost and benefits. 1.1 State Background Delta State is named after the delta region of the River Niger. Its capital is Asaba  [1]  . It is found in the south-south areas of Nigeria. Delta state consists of different ethnic groups like Urhobo, Igbo, Ezon, Isoko and Itsekiri but consist mainly of the Igbo people.Nigeria has a population of 151, 870, 000 people of which Delta state has a population of 4, 098, 291; the males are up to 2, 674, 306 while the females are up to 2, 024, 085  [2]  . Delta state is the second oil producing state in Nigeria after Rivers State, of which this oil production tends to be the most dangerous business in this economy. The local governments that produce oil in the Delta state are Warri North and South, Burutu, Isoko North and South, Ughelli North and South, Okpe, Ethiope East and West, Sapele and Ndokwa East and West  [3]  . The biggest oil refinery is found in Warri, which is a local government in Delta. 1.2 Map showing the location of Delta state in Nigeria: 4Delta State. 1.3 Research Methodology My process of research was divided into two methods; primary research and secondary research. 1.3.1 Primary Research My primary research involved The use of a questionnaire: The questionnaire was created addressing specific questions like; what has the government put in place to help the economy? and also what has the economy benefited from the oil production? A survey was used to get more personal information like; Government share of income and income of Petroleum Company. Interview was done; I interviewed the people living in the villages, the leaders of the town/villages. Asking them what the costs and benefits has been for oil production. I also interviewed employees from the Petroleum company (SHELL) I took pictures of the benefits from the oil production. 1.3.2 Secondary Research Secondary information was gained from the various websites, textbooks and articles. The information includes: a study of economic theory relating to externalities. Textbooks were used to get definitions. The internet was used to review other information that is relating to this topic. The reason for this is to see how this state is managing with its externalities. Internet was used to get background information on the state Internet was also used to get the cost of oil production in the state Images of the cost of oil production in the villages were gotten form the internet. The use of articles in the newspapers was used to get information on the current situation Problems Proposed Solutions Interviews and with the people in villages and the leaders of villages Language barrier Finding someone to help in translating. Interview with the employees of SHELL Release of private company information Use of other sources to get information like the radio, internet, newspapers etcetera Sharing of questionnaire and survey on land Riots in these areas were questionnaires were being distributed Go to areas where there is no riot to distribute questionnaires and do a survey.1.3.3 Possible difficulties and proposed solutions. 2 PRIMARY DATA ANALYSIS The employees and few people living in Delta were given questionnaires to find out certain information, about what the oil industries and the government have done with the economy from the benefit of oil production. The questionnaire was given to 20 employees at SHELL who were randomly selected from various departments and 20 people living in the economy. This section is showing the sets of results gotten from these individuals. Table 1: Results concerning responsibility by individuals in the community Issues Number of people Government Politicians Oil Industries Who do you think is responsible for the pollution in Delta? 20 2 0 18 90% of the people living in the community believe that the oil industries are the cause of the pollution which is right, and it is good to know that only 20% believe that the government is responsible which is not true. Table 2: Results concerning responsibility by SHELL employees Issues Number of people Agree Disagree Unsure Do you think it is your responsibility to make it right? 20 10 4 6 In the above pie chart 50% of the employees at Shell think it is their responsibilty to make things right in the economy that means they sould be able to stop the pollution the oil company is causing. This illustrates that half of the people in company are taking respnsibility for their actions. Table 3: Results concerning responsibility by the individuals in the community Issues Number of people Agree Disagree Unsure Do you think it is your responsibility to make it right? 20 5 7 8 40% of the individuals in the community are not sure whose responsibility it is to stop the pollution in Delta, 35% of the individuals dont think it is their responsibility to control pollution in the economy. This illustrates that most of the people in this community could be seen as ignorant since it is a few that are ready to take some responsibility to make things right. Table 4: Results concerning government action by the individuals in the community Issues Number of people Agree Disagree Unsure Is the government doing anything about the situation? 20 5 12 3 From the pie chart it has been shown that government is not taking action from the negative externality taken place in the state which is not good. From the primary data analysis it is seen that there are some problems Delta such as pollution etc and this is due to market failure. From the economic theory it is seen that if the marginal social benefits is > the marginal social costs or vice versa there would be market failure  [5]  . Market failure is due to the positive and negative externalities in the economy. The next section in this essay is going to state those economic cost and benefits of the oil production in Delta State. 3 INDENTIFICATION OF ECONOMIC COSTS AND BENEFITS. This section will contain the analysis of the economic costs and benefits in Delta state. There are a lot of problems in Delta state such as oil spills, waste dumping and gas flaring. The main problem in Delta is the oil spillage. The type of oil produced in the south-south is deep sea oil, which causes oil spillage and then leads to pollution; air, land and water pollution, the cause of this pollution has led to the damage of soil, water and air. The oil spills has caused farmers in the area not to fish and farm again because the pollution has spread in their sea and lands, thus thousands of people have been affected especially the poor people and those who rely on traditional way of living such as fishing and agriculture. But there are not only costs in the oil production there are also benefits in the fact that the state is making a lot of money in producing oil since oil is needed in a lot of countries. Externality occurs when the production or consumption of a good or service has an effect upon a third party  [6]  . If this effect is dangerous it can therefore be called a negative externality but if the effect is advantageous it is said to be a positive externality. Negative externalities bring about external costs and positive externalities bring about external benefits. The production of oil in Delta state can bring about both external costs and external benefits. 3.1 External Costs from Oil Industries. The people in the economy have endured oil spillage for years now. Oil spills are caused by corrosion of oil pipes, poor maintenance of infrastructure, and leaks during processing at refineries.  [7]  This oil spillage usually happens on the land and in the sea. The cause of oil spills in water is that, the oil has contaminated the water, so the fishes in the sea would die that means there wouldnt be any fishing or it would become poisonous and if it is poisonous when it is eaten the people in the economy would get ill. It could also harm the plants; plants could die because of oil spills and also animals that drink from the water. Also some places in Delta are not yet developed; in those places the people that live there usually have their bath in the sea so if they do that where the water has been affected the people could get skin disease. The oil spills on land would destroy crops; damage the soil the farmers use in farming for their family. The production of oil is making th e rich to get richer and the poor to stay poor and die of poverty. Gas flaring is when gas is burnt unsteadily. Gas flaring occurs when oil is pumped from the ground, this oil burnt then produces gas and the gas produced is burnt as waste in enormous flares. Thus the burning of this gas results to the damage of the environment, especially the areas which are nearest to the oil industries. The government and the industries have done nothing to stop the people from burning the gases and also they havent given any solution to the situation. People in that area are now having health problems; there would be air pollution thus leading to people inhaling chemicals that are not good for their health and sanitation problems; there would be water pollution, chemicals from the gas flare would make water dirty, that is the water the people in the area used to take their bath is going to affect their hygiene because the water would very dirty. The people in this area do not have money for medical bills and they do not have health insurance. The farms of these p eople living in this area have been destroyed so there is no other source of getting money to pay medical bills so this leads to the increase in death rate in that area. When oil is made from the industries, waste are also produced these waste are then dumped on the land and in the sea, thus destroying the environment and weakening the peoples right in their standard of living. The government have not tried anything to stop people from disposing this waste on the land and the sea, they have not realised that the sea has been contaminated by the various mixture of the oil and if they had they would have treated their water. These chemical substances in oil are very toxic and it can affect the people living in the area. People in this areas are dying of hunger, because their farms have been destroyed so there is nowhere else to get food from, farmers are now unemployed because their plants are dying so they have nothing to plant and sell to make money, hunters are also unemployed because the animals are dying due to them drinking water from the sea or eating plants that were poisonous. The children of these hunters and farmers cannot go to school again because there is no money to pay their school fees. Poverty hits these innocent people who depend on livelihoods Due to the negative impacts on the production of oil there have been a lot of complaints by the local communities, because of these complaints it has made some people from this community to become militants. Since the production of oil has caused poverty it has led some of these militants too undergo criminal acts like stealing the oil that has been produced; militants steal this to make money out of it, and also illegal bunkering of oil; that is shipping oil illegally to another country to make money without the consent of the government. Also another cause of militancy due to the production of oil is because the government, the industries and the politicians have refused to do something about the oil spillage, the government has not done anything to develop the state practically because they are gaining from the oil production and keeping the money to themselves; the people from the economy have watched these politicians, governments and the industries get richer so this now leads the militants among them in kidnapping the rich peoples children, there are also armed robberies; these militants rob the rich, and if people are being too aggressive when they are being robbed then the militants might kill them, so this could lead to death, they also take on fights with the Nigerian security forces; this makes the security force to fight back extremely and not considering the people in that area. Militants could go into fraud also known as 419 in Nigeria, they could do business that could cheat people and by cheating them, they could get money from them. All negative things are done because of the government, the industries and the politicians ignorance to the situation. Picture below shows gas flare at Ughelli West, Delta State, Nigeria. 8 Picture below shows the militants with their guns 9 Picture below shows damage of crops because of oil spills. 10 Figure 1: Diagram showing external cost of oil production in Delta State. Price of oil Welfare loss MSC MPC Negative externality P* a p1 Q* Q2 Quantity of oil. In figure 1, it shows that the marginal private cost of the industry is lower than the marginal social costs because of the pollution that was brought about when oil was produced, this pollution might have caused breathing problems for people and also poisoned food like fish. The industry would just be concentrating on its own private costs; because of this the industry would produce at Q1. At Q* marginal social cost is equal to the marginal social benefit resulting to a market failure. Too much oil is being produced at too low a price; this causes the misallocation of the societys resources. There is welfare loss i.e. where marginal social cost is greater than marginal social benefits. There are also negative externalities of consumption i.e. the pollution that is caused and how it affects the consumers. Negative externalities would make marginal social benefits less than the marginal private benefits. Figure 2: Diagram showing negative externality of consumption. Price of oil Welfare loss MSC P1 P* MPB Negative externality MSB Q* Q1 Quantity demanded. In figure 2 it shows that the oil industry keep on producing oil, and there is still oil spillage, they pay no attention to the negative externality they are creating, Marginal social cost becomes equals to marginal private cost. There is over-use of oil from Q* to Q1, there is also a welfare loss because Marginal social cost is greater than Marginal social benefits. It is difficult to reduce this pollution. First of all the costs of pollution are external in the sense that the cost of pollution are not paid for by the agents causing it, so there is no economic incentive in the market system to cause them to stop Second of all the people benefiting from the activities; those are the people producing the oil, they are causing pollution and imposing some costs on others. So the pollution needs to be reduced although the victims are meant to be compensated. 3.2 External Benefits from Oil Industries. The oil industries may have destroyed the communities in Delta but they have also made a lot of money for the state because of the production of their oil. As it is said above Delta state is the second oil producing state after Rivers state. The economy has benefited from the oil production. The money used from the oil production has been used for the improvements of infrastructural facilities such as construction of roads, bridges and provision of pipe borne water which benefits the villagers, increased use of electricity, better transport facilities and usefulness of petroleum products. The biggest oil company in the Delta state, The Shell Petroleum Development Company (Shell), a subsidiary of Royal Dutch Shell, is the main operator on land. Shell is located in Warri. Many Nigerians specifically those from Delta state are employees of Shell, working in an oil company means that those employees would be making a lot of money this means that there would be an increase in income per capita thus an increase in urbanization that means Delta would be more developed in the standard of living. Shell has provided a lot of benefits for the economy and for the workers. Such benefits is the provision of education for the children of the employees at the shell company, provision of houses, cars and also they pay for all the bills of the employees. Shell has contributed money to the construction of new private and public schools, schools for people of low and high classes. There are also schools for the residents of the state that is for those who could not afford to go to school. This is thus increasing the literacy rate in the economy. Educational competitions are organised and also sports to promote academic and physical excellence which benefit the individuals in the state. SHELL has also benefited from its own production of oil such as increased revenue from sales; their increase in production brings about huge profits to the company. There is also an increase in development in the SHELL Company; there is now advance technology like drilling equipment in which they can use to prevent or stop the oil spills. There is also an improvement in International relations such as an increase in production which has led to an agreement with oil consuming economies such as the United States and China. The oil company shell has tried to do its best in developing the economy but because of the corruption problems in Nigeria it affects the economy. The money used for infrastructure development has been taking by the government or the politicians for their own benefits. Pipe borne water that has been installed for the villagers has broken and the government take the money that has been giving to use it to fix it. Oil spills caused by the production of oil has spoilt the road, the money contributed by the economy to fix the roads has been stolen by the government. The public schools where children are meant to be going for free the government waste time in paying teachers their salaries, so these teachers go on strike and refuse to teachers these children, thus making the literacy rate unstable. There are benefits from the production of oil, but because of corruption by the government all the benefits are not taking place. If the benefits take place, there would be positive externalities because of the oil produced. Since there are positive externalities it means that the there would be welfare gain i.e. the marginal social benefit is greater than marginal social cost. The diagram below illustrates where the welfare gain is and that is between Q1 and Q*, it also shows that oil is produced at Q1 , if the production of oil is increased to Q* more welfare would be gained. Figure 3: Diagram showing positive externality. Price Welfare gain MPC P1 MSC P* MSB Q1 Q* quantity. Picture below shows an over-head bridge in Delta. Picture below shows house of a shell employee in Delta Picture showing a factory in Delta Picture below shows one of the good roads in Delta. 4 THE FUTURE This section is going to impose ways the government can control the negative externalities in the state. There are different ways the government can control these negative externalities but first of all the government should stop being ignorant and help the economy. If government stops being ignorant they can enforce laws to control and monitor pollution in the villages; introduce more national and marine; ensure that forestry companies re-plant trees; regulate use of contaminated land. Government can impose tax on oil companies to increase the private costs, if the government should do that the Marginal private would move upwards, there might still be welfare loss but it would be less than before. There should also be subsidies that is the amount of money paid by the government to a producer, it lowers the firms cost, these subsidies could be inform of grants, reduced taxation etcetera. With the money gotten from oil production government can use it to compensate victim of the negative externalities of oil production so that victims would not sue the offending firms. The government can pay damages to victims through free health coverage. Also since oil has now taking over the agricultural production which has caused the farmers and fishermen their jobs cause of the pollution, the government should build centers where they bring in professionals to teach them skills like mechanics, welding, painting, etcetera. If government cant find professionals they can encourage companies there to teach them the skills. If the government does this there would be fewer crises because those people would no longer be unemployed and there would now be less kidnapping, armed robbery, fraud etcetera. But if the oil industry continues with its act of polluting the environment the government should control their output in some way because it will not be possible to ban, if that doesnt work out the government could make new environmental laws and if the oil industry dont follow it then they would have to pay some amount of money since they have disobeyed the law, paying the money would increase their private costs. The diagram below shows the result if the oil industry has to pay tax. Figure 4: Diagram showing negative externality. MSC Price P* welfare loss MPC + tax P2 MPC P1 Q* Q2 Q1 Quantity of oil. Firms should also be able to help, at the moment in Delta state the oil industry that is really helping in the negative externalities in the economy is SHELL. Other firms should take part in helping and do things like changing its production of its techniques and operation like economizing on the amount of waste disposal from the oil production. Changing the materials used in packaging the oil, something that can be recycled should be used that it would be used again thus prevent burning of waste disposal. If government does this for the state there would a short term effect of pollution but in long term there will be no pollution. Therefore there would be less cost on the production of oil and also an increase in economy growth. But if government takes no action there would be a long term effect of oil production, and also a decrease in economy growth and an increase in the negative externalities of the economy. In conclusion it is only the government that has the power in stopping the increase of negative externalities in the economy especially if the industries do no take action, but if government takes no action and continues taking bribes or being corrupt the economy would therefore be suffering for the costs of oil production.

Labor and Childbirth - The Event of a Lifetime Essay -- Observation Ess

Childbirth - The Event of a Lifetime A description can never be as vivid as an event that has been experienced. An experience can never be as defining as an event that has left you changed. Under the intensity of childbirth, you're more likely to remember details that would otherwise go unnoticed. All the scenes come together to leave a permanent imprint on the mind's eye. The hospital room holds all the usual scenery: rooms lining featureless walls, carts full of foreign devices and competent looking nurses ready to help whatever the need be. The side rails of the bed smell of plastic. The room is enveloped with the smell of plastic. A large bed protrudes from the wall. It moves from one stage to the next, with the labor, so that when you come to the "bearing" down stage, the stirrups can be put in place. The side rails of the bed provide more comfort than the hand of your coach, during each contraction. The mattress of the bed is truly uncomfortable for a woman in so much pain. The eager faces of your friends and family staring at your half naked body seem to be acceptabl...

Divine Comedy - Autobiographical Journey in Dante’s Inferno Essay examp

Dante’s Inferno - Autobiographical Journey    The Inferno is more than just a fictional story about someone traveling through the universe. It is actually more like an autobiographical journey of life through its author, Dante Alighieri’s eyes. Written in the early 1300s by a disgruntled Dante living in exile, he literally describes a man who has been trapped, and must find a way to escape. Allegorically, he’s telling us about the terrible moment of crisis that occurs in each one of our lives â€Å"when evil inside and outside of ourselves seems to block any hope for further constructive development†. Written originally as a long poem separated into cantos or songs, he basically wrote with the personal purpose of recording where all of the people he came in contact within his life, will go when they die. This could be one of three places; Hell, Purgatory, or Heaven. He went on to design specific, fitting punishments or rewards based on the life each person led. Dante then tied this all togethor and made hims elf a character that walks the entire length of the conceptualized...

1950’s/ 60’s in Music

The 1950’s and 1960’s represented a turning point for music – it was the first time when teenagers started to have there own image and as a result, their own music. The instrumentation, subject material for lyrics and use of harmony changed drastically in the 50’s and continued to develop into the 60’s. New genres developed at the same time as this turning point such as rock, R&B, swing and pop. The use of electric guitar, drum kit, keyboard, bass guitar and vocals as a common set up started in the 60’s with The Beatles.Songs such as â€Å"Hey Bulldog† and â€Å"Sgt Pepper’s Lonely Heats Club Band† saw the transition from twelve bar blues to rifts and rock. Other genres such as R&B saw use of horns, piano, vocals, background vocals and electric guitar before its demise in the 60’s. Subject material for lyrics in the 50’s tend to be about romance and sorrow. â€Å"AA boy without a girl† by Frankle Aval on contains themes of both love and sorrow, through lyrics such as â€Å"†¦And since you've come to me All the world has come to shine, Cause I found a girl who’s mine. The Beatles broke away from this tradition with their nonsense lyrics in â€Å" I am the Walrus† but other bands did not replicate this. Another trend in the late 50’s early 60’s was to sing about dance and freedom such as â€Å"Jailhouse Rock† by Jerry Leiber and Mike Stoller for Elvis, one of the later songs to continue the use of twelve bar blues. The 50’s progression was a chord progression and turnaround used in the 50’s and early 60’s by doo-wop and later rock. The progression follows the pattern I vi IV V.Well known examples of the progression include The Beatles â€Å"Strawberry Fields Forever† and Penguins â€Å" Earth angel†. A modern version of the progression can be heard in Green Day’s â€Å" Jesus of Suburbia† and Justin Bieber’s â€Å"Baby†. Most classic rock in the 50’s saw use of the twelve bar blues. Twelve bar blues is a chord progression, which most often follows the pattern of I I I I IV IV I I V V I I. With the end of the 60’s came a demise of classic rock and the emergence of new genres such as funk and disco.

Evaluation of Genetic Diversity of Golden Apple Snail, Pomacea Canaliculata

ABSTRACT Genetics is a trend these days especially that, DNA barcoding has been developed. DNA barcoding is an important tool in categorizing the taxa of different species and it tells so much about the species’ traits, including genetic diversity. The Pomacea canaliculata was introduced in different parts of Asia and had been an invasive species and a pest in different ecosystems ever since the introduction. In understanding this species of snails, samples were collected, DNA’s were extracted, undergone PCR and electrophoresis, and was sequenced and analyzed.The analysis was qualitative In the Philippines while quantitative in China. In the Philippines, the cytochrome oxidase subunit 1 (COI) genes was used and compared among the species collected and when it was sequenced, it showed differences due to localized gap, mismatch and non-correspondence of bases. And in China, the diversity was analyzed by means of Nei’s gene diversity, Shannon’s information in dex, percentage of polymorphic bands (PPB) an AMOVA anlysis. Both the quantitative and qualitative showed that there was diversification within and among the populations of these snails.INTRODUCTION Genetics is the study of the genes, and the heredity and variation of individuals. Understanding the genome, which is the complete set of chromosomes or the entire genotype of an individual, is important because it helps in the taxonomy of species, especially nowadays wherein advancements in science needs more specific information, and that basing on morphological features is not enough. Life is specified by genomes which contain all the biological information which is encoded in its deoxyribonucleic acid (DNA) and divided into units or the genes.The genes are the blueprint for life because it is the particulate determiner of hereditary traits. Hence, DNA barcoding became a trend for scientists and researchers for the understanding of the different variations in the traits of different o rganisms. The golden apple snails (Pomacea canaliculata) originated from the South America, Central America, the West Indies and the Southern USA (Pain 1972) and was spread in the past decades to the different parts of Southeast Asia, namely Philippines, China, Thailand, Cambodia, Hong Kong, Indonesia and Japan.The introduction of the P. canaliculata without prior studies caused damages to the different plants and it became an invasive species which resulted to becoming pests to humans and competitors to other local snails, example of which are those from the genus Pili. The P. canaliculata was observed to have different growth and reproduction in different parts of Asia, together with their external characteristics due to the different habitats and environmental conditions (Keawjam, 1986 and 1987), therefore there is the possibility to misidentify two sympatric species as one.On the other hand allopatric populations inhabiting different habitats may show ecomorphological variations and questionable species status and it was also suggested that the golden apple snails had high adaptability hence it was easier for them to form new populations (Dong et al. 2011). The understanding of the genomes of different species is a trend for scientists these days but the information about the different mollusks is still limited. The basic information on the number of species and/or population is of help for conservation programs (Carvalho and Hauser, 1994) and for building appropriate management schemes.In contribution, the studies aims are to evaluate the genetic diversity of the golden apple snail population in Asia, namely, Philippines and China via molecularly characterizing the P. canaliculata and to find different ways of analyzing the gathered data from the sequenced DNA of the said species. REVIEW OF RELATED LITERATURE Genetic diversity (Reed 2005) The significance of genetic diversity arose from two necessities: genetic diversity is required for populations to evo lve in response to environmental changes and heterozygosity levels are linked directly to reduce population fitness via inbreeding depression.The amount of genetic variation a population contains is predicted to correlate with current fitness and, in the case of heritabilities (which can remain high or even increase despite severe reductions in population size) with evolutionary potential. This correlation between fitness and levels of genetic variation, however, may be weak or nonexistent due to the neutrality of molecular markers used in estimating heterozygosity, nonadditive genetic variation and the purging of deleterious alleles because of increased selection against homozygotes.There is a body of literature that suggests that allozyme heterozygosity is a good measure of population fitness and adaptive potential. Others caution though that such molecular genetic data generally reflect only a small portion of genome and thus may not be indicator of adaptive genetic differences. But molecular markers may be useful for assessing the extent of genetic drift. Moreover, deleterious alleles, in mutation-selection balance, are responsible for at least half of the genetic variation in fitness.Selection has the tendency to purge the population of the deleterious recessive alleles which in theory creates inbred populations with a higher fitness than their outbreed progenitor. In other words, inbred populations with less genetic diversity would have higher fitness if the population is not kept small enough for a long enough to allow the fixation of deleterious alleles to occur. Fitness and future adaptability are reduced in smaller populations of plants and animals due to drift and inbreeding depression.Commonly used surrogates for fitness such as heritabilities, heterozygosity, and population size, significantly correlate with fitness and explain 15-20 % of the variation in fitness. Correlations suggest that many populations have reduced fitness as a result of inbre eding depression and genetic drift. There is much fuss and concern thus, over genetic variation because of the fact that endangered species typically have lower levels of heterozygosity and the loss of adaptive genetic variation and inbreeding depression puts wildlife populations at an increased risk of extinction.Finally, this increase occurs as a result of the reduction of productive fitness because of inbreeding depression or due to the failure of tracking the change in abiotic and biotic environment of the population as a result of the loss of genetic variation through drift. DNA barcoding (Moritz & Cicero 2004) At the very core, the purpose of DNA barcoding is for large scale screening of one or a few reference genes in order to assign unknown individuals to species and enhance discovery of new species.In the hope of developing a comprehensive database of sequences that will serve as a comparison tool to sequences from sampled individuals, proponents used DNA barcoding. There i s, however, nothing new with DNA barcoding as it is an offshoot of the use molecular markers for the very same purpose except, in DNA barcoding, there is an increased scale and proposed standardization. The selection of one or more reference genes characterizes standardization, with regards to microbial community and in stimulating large scale phylogenetic analyses if of proven value, though whether or not one gene fits all remain to be a question.Presently, most methods of DNA barcoding are tree-based and can fall into two broadly defined classes. One class is the distance-based, wherein it is based on the degree of DNA sequence variation within and between species. This kind of approach converts DNA sequences into genetic distances and then uses these distances to establish identification schemes. It further defines a similarity threshold below which a DNA barcode is assigned to a known or a new species. There is also the mention by several authors of a â€Å"barcoding gap† , a distance-gap between intra- and interspecific sequences, for species identification.However, the distance-based approach seems to be ill suited as a general means for species identification and the discovery of new species. One reason is that substitution rates of mitochondrion DNA vary between and within species and between different groups of species. The varied substitution rates can result in broad overlaps of intra- and interspecific distances, and hinder the accurate assignment of query sequences. Another class which is the monophyly-based requires the recovery of species as discrete clades (monophyly) on a phylogenetic tree and is used to assign unknown taxa to a known or new species.Similarly, some issues complicate the use of monophyly in a barcoding framework. For example, the long-recognized problem of incomplete lineage sorting will yield gene genealogies that may differ in topology from locus to locus. The recently divergent taxa may not be reciprocally monophyletic due to lack of time needed to coalesce. In addition, the gene trees are not necessarily congruent with species trees, and the monophyly, while a discrete criterion is arbitrary with respect to taxonomic level.Moreover, there is a recently applied new technique that has been proposed as an alternative to tree-based approaches for DNA barcoding, the so called character-based DNA barcode method, which is based on the fundamental concept that members of a given taxonomic group share attributes that are absent from comparable groups. It is the kind of method that characterizes species through a unique combination of diagnostic characters rather than genetic distances. The four standard nucleotides (A,T,C,G) if found in fixed states in one species can be used as diagnostics for identifying that species.This way, species boundaries can be defined by a diagnostic set of characters which can be increased to any level of resolution by applying multiple genes. Presently, character-based DNA b arcode method has been proved useful for species identification and discovery of several taxa. In the view that single-gene sequence should be the primary identifier of species, a contention arises that if that is the case then there’ll be a real need to connect different life history stages and increase the precision and efficiency of field studies involving diverse and difficult-to-identify taxa.Although the DNA barcoding community has put emphasis on the importance of large-scale sequence database within the existing framework and practice of systematics, it should be bore in mind that DNA barcoding is not the primary answer in resolving the tree of life. Furthermore, as much as the term â€Å"DNA barcoding† appealing, it implies, however, that each species has a fixed and invariant characteristic. But this kind of implication renders unrest to the minds of evolutionary biologists.In evaluating thus, the promise and pitfall of DNA barcoding, two areas of application should be distinguished: the molecular diagnostics of individuals relative to described taxa and DNA-led discovery of new species. And although there is little doubt that large-scale and standardized sequencing, when integrated with existing taxonomic practice, can contribute significantly to the challenges of identifying individuals and increasing the rate of discovering biological diversity as presented by this study, the general utility of DNA barcoding still requires further scrutiny.PCR (Moore 2005) In rapidly copying a selected template sequence from a DNA mixture in vitro, PCR offers a wide range of applications such as sequence detection and isolation for research, forensics and species identification through the PCR itself and in combination with other techniques. PCR's new technique uses flourescent probes to monitor the amounted product at end of every cycle and PCR machines look for the cycle at which the can readily detect flourescence.PCR is also being used to monitor RNA through the addition of reverse transcriptase enzyme at the beginning to generate DNA template. In addition, there are now new applications of PCR like single nucleotide polymorphism detection and screening. Cytochrome Oxydase subunit 1 (COI) (Buhay 2009) COI plays a significant role in documenting biodiversity and remains to be the choice for phylogenetic and phylogeographic studies. COI is a mitochondrial protein-coding gene which is a widely accepted marker for molecular identification across diverse taxa.Mitochondrial DNA (mtDNA) have a relatively fast mutation rate, thus they result in significant differences between species. With respect to this, the mitochondrial cytochrome c oxidase subunit I (COI) gene with ~700bp was proposed to be a potential barcode or marker for molecular identification across various taxa. Furthermore, COI is a protein coding gene that has an open reading frame and in thecase of barcoding, COI can be highly divergent from the actual COI sequences which may cause major problems because species identification is based on sequence similarity.Pomacea canaliculata (Cowie 2002) The Pomacea canaliculata belongs to the family Ampullariidae. Its structure appears to have a slight dimorphism in shape of aperture and operculum. Females have broader mouth and concave operculum while convex in male. In terms of reproduction, oviposition often takes place at night or at early morning or evening about 24 hrs after copulation up to two weeks after mating (occurs three times per week) which occurs anytime of the day or night although there may be some diurnal rhythm.On each oviposition occasion a single clutch is laid of highly variable egg number. Moreover, the interval among successive ovipositions for p. canaliculata has been reported to be about five days and hatching generally takes place about two weeks after oviposition. The P. canaliculata breeds only during summer and grows into maturity in less than two months. P. canaliculata is s aid to be prolific and hence has rapid succession of generations which leads to rapid population expansion.They relatively inhabit still water and in water temperatures above 32 degree Celsius, it has been observed that the mortality of p. canaliculata is high. Whereas in low temperature p. canaliculata can survive 15-20 days at 0 degree Celsius, 2 days at -3 degree Celsius but only 6 hrs at -6 degree Celsius. And it is sufficiently tolerant of sea water to survive long enough to be carried by currents from one stream mouth to another, thereby expanding its distribution. P. canaliculata shows preferences among food plants.Its rate of growth has a direct correlation with its feeding on the preferred plant. Moreover, it is able to detect its food plants from some distance using chemical cues in the water. P. canaliculata, however, appears to be relatively generalist and indiscriminate that it is viewed to be particularly voracious compared to other Ampullariids. METHODOLOGY Sampling S nail samples were identified and collected from 2 countries in Asia, specifically in the Philippines and in China, where the P. canaliculata was introduced. In the Philippines; Los Banos (Dong et al. 011, p. 1778), 2 barangays in Tarlac (Brgy. Cabayaoasan, Paniqui and Brgy. Pance, Ramos) and Iloilo (Chichoco & Patdu 2012, p13), 44 snail samples were collected. And in China, specifically from Yuyao and Taizhou in Zhejiang province, Fuzhou in Fujian province, Guangzhou in Guangdong province, Nanning in Guangxi province, Kunming in Yunnan province, wherein a total of 120 samples were identified with the conserved sequence by Matsukura et al. (2008) and Pan et al. (2009) and then was collected (Dong et al. 2011, p. 1778).The snails were then stored, either by wrapping in paper, freezing or preserving it in ethanol, and brought into the respective labs in each country for the next steps; DNA extraction, PCR, electrophoresis and sequencing. DNA extraction The two studies used the phenol-c hloroform method (Bergallo et al. 2006) with an alternative of the Qiagen’s Dneasy extraction kit for China. The DNA concentration was determined spectrophotometrically and adjusted by a mini-gel method (Maniatis et al. , 1982) when the extracted DNA was enough, it was stored at 4oC to -20oC until needed. PCR and ElectrophoresisThe PCR method was basically done by choosing the right primers that will yield clearly reproduced bands and they tested the proper amounts and amplification effects of the components of PCR, which were the Mg2+, dNTP’s, DNA templates and polymerase, and the primers. After the mixture of the components and the DNA extracted, it was carried out in the thermocycler programmed for pre-denaturing at 94 °C for 3 min, followed by 26 cycles of 94 °C for 10-30s, 36-52 °C for 30-45s, extension of 65-72 °C for 60-90s, and the final extension for 5-7mins at 72 °C for final extension with 38-48 cycles.After which, the amplified products together w ith negative controls were run in electrophoresis to be separated and tested for contaminations, respectively. The products were then purified later on with the respective kits present in each lab. In the Philippines, the reaction was done with 2? L MgCl2, 5? L PCR buffer, 1? L dNTP, 2. 5 ? L of the primers, which were the LCO1490 and HCO2198, distilled H2O with 22. 75 ? L, 0. 25 Taq, and 10 ? L Q-buffer. The electrophoresis was done after the ethidium bromide staining (Maniatis et al. , 1982), analyzed through 1. % agarose gels and visualized under a transilluminator. In China, they made use of the ISSR-PCR analysis where they got four primers, which produced clearly reproduced bands, out of the 90 that was screened from the University of British Columbia’s primer set and the reactions were done with a volume of 20 ? l, containing 0. 2 mM of each dNTP, 1. 5 mM MgCl2, 0. 5 ? M primers, 1 U Taq polymerase and 10 ng DNA template, and also with the determination of the optimal r eaction system of ISSR for P. canaliculata (Dong et al. 2011, p. 1779).The products’ sizes after the amplification was estimated using DNA marker DL2000 and then was run in electrophoresis, which was done on 6% polyacrylamide gels, visualized by silver staining and then photographed (Li et al. , 2009). Sequencing/ Data analysis Chichioco and Patdu (2012) sent the DNA samples to the First Base Laboratory in Singapore for sequencing and the results were sent back to the DNA barcoding Laboratory after a week. The COI sequences were aligned in the BLAST, specifically the STADEN package version 1. 5. 3 and Bioedit Sequence Alignment Editor version 7. 0. 9. 0.Aside from the sequences sampled, other sequences and their haplotypes from the GenBank were also compared and matched. In Dong’s (2011) research, he made use of the RAPD fragments by labeling them into binary matrices, used them to get the similarity index, Sxy = 2nxy / nx+ ny, where nx and ny represent the number of R APD bands in individuals x and y, and nxy represents the number of shared bands between individuals, as stated by Nei and Li (1979), then averaging it across all the possible comparisons between individuals within a geographic sample to get the within samples similarity (Si).Between sample similarity corrected by within sample similarity Si and Sj of geographic samples i and j, respectively) is also calculated between pairs of individuals across samples i and j using the equation; S’ij = 1 + Sij – (Si and Sj)/2. Genetic distance between paired samples was then calculated as D’ij = 1- S’ij (Lynch, 1990). RESULTS AND DISCUSSION In the Philippines (Chichioco & Patdu 2012, p. 18-31) The collected samples from Brgy. Cabayaoasan were found in the elevated parts of a rice paddy, specifically, it was a muddy substrate with decaying leaves from the rice plants and surrounding trees while those that was found in Brgy.Pance was in the muddy bottom of the shallow fis h pond in the roots of water lilies and grasses. The samples from the two barangays in Tarlac and Iloilo had relatively different colors and sizes. Those that were collected from Brgy. Cabayaoasan had the largest size and they are colored black while those in Brgy. Pance had brown in color and still, those in Iloilo had very small sized specimens and some of the specimens can be mistaken as Pila conica snails if not examined properly. Primers affect the amplification success greatly, since according to Hajibabaei (2005) a 95% success is necessary for barcoding.The primers LCO1490 (SENSE) and HCO2198 are generally used for the amplification of forward and reverse fragments from COI genes. The DNA samples were subjected to the PCR and agarose gel electrophoresis (AGE), and they produced single discrete bands that suggest that the fragments were homogenous and start and end at the same point (Reece 2004). The bands that were brighter and distinct are more appropriate for sequencing bec ause it means that the DNA fragments were well amplified. The best DNA’s were chosen and forwarded to the First Base Laboratory in Singapore for sequencing.At the return of the results, other sequenced DNA barcodes were also collected and was aligned and compared with the Basic Local Alignment Search Tool (BLAST) database. Fig 1. Alignment of the COI gene sequences of the Pomacea canaliculata (CPT1-5 from Brgy. Cabayaoasan, PRT 7,9,10 from Brgy. Pance, IICK & IIPC1,3 from Iloilo) from the Philippines using Bioedit Sequence Alignment and ClustalW multiple Alignment (Chichioco & Patdu 2012, p. 26) By aligning the sequenced data, it can be seen that there are both similarities and differences among the genetic make-up of the samples.The differences are due to localized gap, mismatch and non-correspondence of bases along the COI fragments as pointed out in fig. 2 Fig 2. Comparisons of the COI sequences of the P. canaliculata samples from 35bp- 120bp (Chichioco & Patdu 2012, p. 28 ) As emphasized in fig. 2, on the 55bp-58bp, a sequence from CPT1 was observed having (5’-AATT-3’) while all the others have (5’-GGTA-3’). Even though this is a noticeable difference and could have been caused by mutation or variation, the difference is still low enough and less that 1% difference to be considered significant.But on the other hand, the PCa1 sample had 36 different base pairs compared with the others, which was 5. 5% difference and is high enough and can be considered significant since it is ;4% divergent(Meyer and Paulay 2005). Then with a ~98% confidence, it could be said that PCa1 is from an independent evolutionary lineage and might indicate a divergence within or outside its population or might have occurred due to relationships and interactions among the other species.The introduction of the P. canaliculata to different places may have an effect on its intra- and interpopulation and might be why it has various genetic sequences altho ugh it goes against the theory that introduced species becomes a founding population in a new habitat thus they have a limited gene pool and as a consequence genetic drift, which removes variability since it affects all genes, and bottleneck might occur, which reduces the new species to have a reduced genetic diversity.To observe the genetic variability, the sequences collected were compared with those from GenBank with the use of the BLAST software. As a result from 81 COI barcodes and 55 haplotypes, the samples collected showed 99% and 100% similarities with the different haplotypes thus it showed that the species has a high diversity within the populations. The phylogeography within and among the species does not apply on the P. analiculata since intra- and interpopulation diversity was observed which was shown by the multiple introduction throughout the Philippines, hence the different times of the introduction contributed more to its diversity and it coincides with the migrant pool model that says that the introduced population acquires more genetic variability because of the multiple sources of genetically divergent populations as compared to that of the local species (Slatkin 1997, Sakal et al 2001). In China (Dong et al 2010) The chosen primers an average of 124. bands, since they generated a total of 498 bands, which ranged from 150-2500bp and qualifies them for barcoding, as seen in table 1. Among the 140 individuals, 435 bands were polymorphic which was different for each primer. In table 2, Nei’s gene diversity (H) varied between 0. 2612 and 0. 3340, with an average of 0. 3044, and arranged in a descending order the populations, LB ; KM ; NN ; FZ ; TZ ; GZ ; YY while the Shannon’s information index (I) ranged from 0. 3910 to 0. 4856, with an average of 0. 4499.At the species level, the values of Nei’s and Shannon’s showed the same trend as that of PPB. AMOVA analysis showed that there are highly significant (P ; 0. 001) genetic differences among the seven populations of P. canaliculata. The genetic diversity was mostly due to the differences within the population (92. 76%) while the rest was due to among populations. The analysis tells the same as that of the Nei’s and Shannon’s information, which says that there was a relatively high level of genetic differentiation among populations. CONCLUSIONGenetics of different species are studied by means of DNA barcoding, mostly of the COI gene in the mitochondria, to know the taxon of a species and to understand their trends and characteristics not only morphologically but also genetically. The diversity of a species can also be tested by means of DNA barcoding as seen in the study of the Pomacea canaliculata. The P. canaliculata was introduced in Asia for agricultural purposes and was seen for its benefits but not its drawbacks, which later on resulted to it being invasive and a pest for both humans and other species.To understand the P. can aliculata further, its diversity was studied by means of DNA barcoding and was analyzed both qualitatively and quantitatively in the Philippines and China, respectively. Both the analysis showed the same outcome, wherein the results showed high levels of genetic diversity among populations. Because invasive species tends to give a negative feedback to those species in the local area, it is important to understand these alien species and to know how diverse they are so that proper management of these species could be done.
