Harry Potter And The Chronicles Of Narnia - 1163 Words

Growing up everyone is forced to read. First, children start by being read to by their parents and then slowly over time and learning, read for themselves. Children usually at this point either quit reading all together or continue to endure and learn into classical readings such as: Harry Potter, or The Chronicles of Narnia. Kids who go through school are forced to read to increase their comprehension skills, and the ones who read on their own outside of school as well, usually have an increased score than others. Mostly people who do not read on their own have trouble connecting with the books or reading that they try. They seem to not be able to stay focused on the book, and easily become distracted with other things. Growing up I was a kid like this. I still to this day struggle with not becoming distracted with other things while I am trying to read. I always start with good intentions and then halfway down any certain page, I find myself daydreaming about something random like what I had for dinner the night before. I always had this problem, until now. During this summer literature course I have had a new inspiration for reading. From the first short story we read, The Notorious Jumping Frog of Calaveras County, to the last I was surprised how interested I was in the stories. I didn t find myself daydreaming in the middle of these stories, and instead, I was focused and intrigued on how it would end.

Freedom of the Press Versus Right to Privacy Free Essays

Privacy has become a big issue in contemporary jurisprudence. The â€Å"right to privacy† is enshrined in the United Nations Declaration of Human Rights, and guaranteed by Article 8 of the European Convention on Human Rights. But Article 8 is balanced by Article 10, which guarantees â€Å"free expression of opinion†. We will write a custom essay sample on Freedom of the Press Versus Right to Privacy or any similar topic only for you Order Now So what right has priority when they conflict? Under what circumstances, for example, is it right to curtail press freedom in order to protect the right to privacy, or vice versa? The same balance is being sought between the right of citizens to data privacy and government demands for access to personal information to fight crime, terrorism, and so on. Freedom of speech is a fundamental democratic liberty. It is a necessary protection against abuses of power and cover-ups of wrongdoing by public officials. It was never more effectively displayed than in the Watergate investigation, which brought down Richard Nixon in 1974. But one can have too much press freedom. Over the years, the tabloid press has become increasingly intrusive, claiming the right not just to expose corruption and incompetence in high places, but to titillate readers with scandalous revelations about the private lives of the famous. What started off as entertaining gossip about royalty and film stars has burgeoned into a massive assault on privacy, with newspapers claiming that any attempt to keep them out of the bedroom is an assault on free speech. The issue has just been tested in Britain’s High Court. In March, Britain’s leading scandal sheet, The News of the World, published an â€Å"exclusive† front page story, under the headline â€Å"F1 Boss Has Sick Nazi Orgy With 5 Hookers†. It told how Max Mosley, President of the Federation Internationale de l’Automobile (FIA, the body that oversees world motoring and racing) and son of the former British fascist leader, Sir Oswald Mosley, had, two days earlier, taken part in a sadomasochistic â€Å"orgy† with a â€Å"Nazi theme† in a private apartment in London. The story was accompanied by photographs taken clandestinely by one of the women in cooperation with the News of the World, which readers were invited to download from the paper’s website. Max Mosley admitted participating in this (not illegal) happening, but sued the News of the World for breach of privacy; the newspaper argued that it was in the â€Å"public interest† that Mosley’s sexual activities be disclosed. The presiding judge, Justice Eady, rejected the newspaper’s defense, and awarded Max Mosley 60,000 English pounds ($115,000) compensation for the invasion of his privacy, the highest damages so far given for a complaint brought under Article 8. There is a curious aspect to Eady’s judgment. He rejected the News of the World’s â€Å"public interest† defense, because he found no evidence that the sadomasochistic party had a â€Å"Nazi theme†. This implies that had there been a Nazi theme, it could have been legitimate to publish it, given Mosley’s position as FIA president. But surely the particular nature of Mosley’s private fantasies is irrelevant to the case. It is hard to see why I am less entitled to privacy because I am turned on by a Nazi uniform than I would be if I were excited by a pair of knickers. What Eady’s judgment did accomplish was to highlight the crucial distinction, necessary for all clear thinking about privacy, between what interests the public and what is in the public interest. So how can this distinction be made effective? France has a privacy law that explicitly defines both the scope of privacy and the circumstances in which the law applies. By contrast, in Britain it is left to judges to decide what the â€Å"right to privacy† means. There is a natural fear that specific legislation designed to protect privacy would muzzle legitimate press inquiries. At the same time, it is widely acknowledged (except by most editors and journalists) that a great deal of media intrusion is simply an abuse of press freedom, with the sole aim of boosting circulation by feeding public prurience. A law that curtails the abuse of press power while protecting its freedom to expose the abuse of political power would be difficult, but not impossible, to frame. The essential principle is that the media should not be allowed to pander to the public’s prurience under cover of protecting the public interest. What famous people – indeed ordinary people, too – do in private should be off limits to the media unless they give permission for those activities to be reported, photographed, or filmed. The only exceptions would be if a newspaper has reasonable grounds for believing that the individuals concerned are breaking the law, or that, even if they are not breaking the law, they are behaving in such a way as to render them unfit to perform the duties expected of them. Thus, a pop star’s consumption of illegal drugs may be reported, but not his or her sexual habits (if they are legal). The private life of a politician may be revealed if it is expected to have consequences for the way the country is being governed; that of a top executive of a public company if it may affect the returns to shareholders. This should be the only â€Å"public interest† defense available to a media outlet that is sued for invasion of privacy. The media might become a bit drearier, but public life would be far healthier.

Communication & E-Communication Strategies †Myassignmenthelp.Com

Question: Discuss About the Communication E-Communication Strategies? Answer: Introduction Communication plays a very vital role in any organization, effective communication channel is the key to success of any organization. In an organization, communication is used to communicate with the employees, suppliers, customers and public. Various methods of communication are used by an organization, the standard methods of communication (Kaul 2014). E-communication E-communication means electronic communication, it is the process through which message is transferred through advanced electronic techniques, like computers, modems, facsimile machines, voice mail, electronic mail, teleconferencing, video-cassettes and private television network. E-communication has gained popularity from the very beginning of the millennium. In the recent times, there has been an increase in the usage of modern methods of technology for communication through electronic devices, like computers. E-communication speeds up the communication process( Kaul 2014). Non-E-communication Non-Electronic communication methods are those in which the communication is done without the usage of electronic devices, in formal communication Non-electronic communication is done either orally or through written communication (Kaul 2014). Communication strategies of Apple The communication strategies used at Apple Inc are designed to support the processes and operations of the organization, within its premises also beyond the premises of the organization to communicate with its employees, suppliers, customers and public (Apple.com 2017). Non-electronic communication used by Apple To communicate with its employees, the non-electronic methods that Apple uses are oral and written communication methods. The oral methods of communication are mostly used by Apple Inc. includes speaking. Most of the information and instructions are transferred through oral communication, by speaking. Even the employees mostly communicate and share information related to work orally. Oral communication saves time and one gets instant feedback in oral communication within the premises of Apple, whenever there are a need for quick feedback the employers and the employees use oral communication. The upper management communicates mainly by speaking, all that messages that are of less significance are usually communicated through speaking (Apple.com 2017). Whenever the employers want to provide organization related information it is communicated through notices. Important information about meetings, events are put on the notice boards of the all the offices of Apple. Circulars are issued in Apple, to its employees to communicate the dress code, new changes in the company policies, information about date, timing of meetings and luncheons. The Company issues formal letters to the employees when the employers want to communicate to any employees and the message is not directed to other employees. Employees whenever they want to communicate to the employers, regarding leave and other issues, all the communication from the employees to the employers are done through an application or formal letters, like leave application, resignation and many more Communication with the suppliers is mostly done through electronic communication methods. The non-electronic method that Apple uses to communicate with its suppliers are mainly written, the Compa ny uses formal business letters. Apple Inc. writes formal letters to its suppliers, for making queries related to supplies, price quotations, which are very confidential matters are communicate through formal letters. Written form of communication serves as evidence in case of legal obligations, therefore business letters are used by Apples for future records (Patrutiu-Baltes 2016). Apple communicates with its customers through a number of methods the Company mostly uses electronic methods. To communicate with its customers, there are few non-electronic methods that Apple uses for communication are using, newspapers, magazines and business letters. Newspapers and magazines are used for advertisements and promotional purposes, the company business letters are used to advice, suggest the customers in responses to the queries made by them (Cosman 2013). To communicate with the public, the non- electronic method used generally depends on the purpose of communication, for issuing its annual report the company uses written communication, advertisements and promotional activities are done through the help of print media as well like, publications in books, journals, magazines, newspapers, billboards and many more (Olson and Olson 2014). The Electronic methods used by Apple for communication Apple communicates with its employees, mostly through electronic methods, mainly e-mails, and telephonic conversations. Apple Inc uses e-mails for communicating information, related to work, company policies and code of conduct and other important information. To communicate with the suppliers emails are used. Formal letters are also sent through e-mails. Telephonic conversations are used to communicate with the employees. Meetings are conducted through video conferencing to solve the distance barriers. To communicate with the suppliers Apple writes a business letters through emails, for its suppliers Apple Inc. its uses its website to communicate to its customers and public( Bell and Muir 2014). SWOT analysis of communication methods followed by Apple Inc. Strengths- Apple uses both electronic and non-electronic methods of communication, to communicate to its employees, suppliers, customers and public. Written communication serves as an evidence for future in case of any legal obligations. Apple uses many new and efficient technologies for communication within the organization and also outside the organization. Apples channel of communication with its customers is very good, they communicate through chats and calls as well, which is very good for customers because they get instant feedback and hence they are satisfied with the communication practices. Apple also uses social networking sites for communicating with its customers and public (Newcombe et al. 2015). Weaknesses- Apple Inc is very much dependent on electronic communication, which is not good, in case of technical faults, or network issues the electronic communication completely fails. The electronic communication is very costly because it includes costly devices. Oral communication cannot be used in transmitting important and confidential messages, also it cannot be showed as evidence in future, if the company faces any legal obligation. Written communication because of it being formal in nature, it is a very complex process, the sender of the message needs to focus on the format and the standard pattern of the business letters, notices and circulars (Locker and Kienzler 2013). Opportunities- With more new technologies in the future there is an opportunity of Apple to improve its communication practices with its staffs, customers, suppliers and public. Threats- Most of the electronic methods of communication needs network and internet connections, problem arises due to poor network connections. Cyber security issues often pose threat and disrupt the proper communication process. Noises often disrupt the communication process. Various communication barriers also pose a threat to the communication process (Kuehn 2016). It is seen that communication strategies and the practices adopted by Apple is quite efficient, except for few loopholes, like too much dependence on electronic methods of communication, using oral communication very often, which is not good because oral communication does not serve as evidence for future, unless it is being recorded (Kiesler 2014). Communication practices of the competitors of Apple Inc Samsung Group One of the main competitors of Apple is samsung variety of electronic products, including mobile phones, televisions, laptops, computers and many more. The company is a south Korean head-quartered in Seoul, South Korea. The communication methods and practices of Samsung group is not much different from that of Apple (Samsung.com, 2017). Samsung also uses both electronic and non-electronic methods for communication with their employees, staffs, suppliers and customers. The communication strategies of Samsung for advertisements are very impressive, Samsung uses online banners for advertising, and they focus on the variety of electronic goods they offer to the customers. One such new strategy adopted by Samsung which is a part of their overall corporate communication strategy. Samsung realized their drawbacks in communication system and they knew that there is a requirement of fully interactive system. The new communication system is very effective, keeps the whole department updated, about the progress of the various departments (Kaul 2014). Sony Mobiles Sony Mobiles is another competitor of Apple Inc., it is a multinational tele communications company and a joint venture between Sony and Ericsson, the company has its headquarter in Tokyo Japan, the company is Wholly owned by Sony. Under the brand name Sony Mobiles the company smart phones with impressive features (Sony Xperia Blog 2017). The communication methods used by Sony Mobiles include both electronic communication and non-electronic communication methods, to communicate with its, employees, customers, suppliers and public. Sony Mobiles have a website, which the company uses for business communication with its customers and public, for advertisements brand promotion and also to resolve the queries of customers. To communicate with its suppliers the company uses business letters, to communicate within the organization they have a fine communication practice comprised of electronic communication methods, like use of emails, video conferences for meetings and telephonic communication. The non-electronic methods of communication used by Sony Mobiles include notices, letters and circulars (Dinnie 2015). Recommendations for effective communication methods Apple Inc. should follow a communication strategy that is a combination of both electronic and non-electronic communication system, too much dependence on any one of them might not be an effective communication practice. Devices used for electronic communication should be checked from time to time or else there will a disruption in communication process. Whenever the company is communicating important information to their employees, suppliers, customers and public they should use written form of communication. In the organizational meetings the company should record everything that is communicated for future records. For oral communication the place selected should be free from all kinds of noises, so the communication process is successful. In written communication the message should be very clear and jargons should be avoided. References Apple.com. 2017. Apple Info - Apple.

Farewell To Arms Essays - Ernest Hemingway, A Farewell To Arms

Farewell To Arms The book A Farewell to Arms, written by Ernest Hemingway, is a classic about the love story of a nurse and a war ridden soldier. The story starts as Frederick Henry is serving in the Italian Army. He meets his future love in the hospital that he gets put in for various reasons. I thought that A Farewell to Arms was a good book because of the symbolism, the exciting plot, and the constant moving of the main character. The symbolism in A Farewell to Arms is very much apparent. Ernest Hemingway has always been one who is big on the symbolism of night as being bad. To the main character in Hemingway's novels, nights have always been a sign of death, or something negative to happen. Another one of the symbolisms in A Farewell to Arms is when Henry tries to escape from the Italian army by jumping off one of the ships the army was traveling on and running away from the army. This symbolism was the water that he jumped into was a symbolism of the new, clean life that he was going to live from now on. At this time, Henry goes off and finds his wife to be. The plot in A Farewell to Arms was always active. They were never staying in one place too long. It had a very good story line, which was a love story that ended up in a tragedy. The main character's wife got pregnant and she was off to have her baby when problems started occurring. They had to have a caesarean, and the baby dies, and when the mother of the child starts to hemorrhage Henry knows that it was over for his wife and he was right. From the beginning of the book until the end, the action was up. Ever since the front page Henry was traveling around to different towns so it was not boring for the reader. That made it very interesting for the reader because it was always a new town coming up so they were being introduced in the new characters quite often. As the story goes on, the reader is not introducing as many new people, but they are still traveling around quite a bit. Hemingway has a way with arranging the plots of all his stories. They all have that right timing to them. He always introduces only people that will affect the story, he does not introduce someone who will be in the scene for five minutes and then leave. I felt that the author's planning on putting this novel together was very good. Ernest Hemingway has always been one of the world's best known classic writers. His style and technique of symbolism is much different than others. He uses then in very strong ways that you the reader does not always pick up. I am sure that I missed some of the symbolism that went on in the book. I picked up a few though and they were very interesting. I recommend this to anyone who is interested in a love story that does not get too intimate.

Free Essays on Ancient Greek Theater

For example, when native people talk to foreigners, they tend to speak more slowly or when adults talk with children and babies, they use simple language (Griffin, 2008). When put into context, it means that people accommodate others by adjusting their communicational behavior to match the level of those they are with, in a conversation. The results of accommodation are ultimately either divergence or convergence. As their names suggest, a convergence result is where a person moves their speech to be closer to that the other person’s. On the other hand, a divergence result is when the speech move away from each other. Convergence result allows the reduction of the social distance between the two conversing parties. It allows a person who is of a higher class to tone down their speech so that they can communicate effectively with the lower class person. On the contrary, the divergence resul t increases the distance between people. The divergence result emphasizes the differences that exist between people. The accommodation theory has many existing and available means by which it may be applied. Currently the accommodation theory is applied to many communication processes. Gasiorek and Howard (2013, 15) opines that in a company or an organization that has different levels of employees, the accommodation theory can be applied to aid the communication between the management and the employees. For instance, it is used for horizontal communication amongst the employees and in vertical communication between employees and senior management. To test this theory, Giles came up with several theories that served to test why people change

Analyze one week of world economy - Essay Example Also to be noticed is the fact that these figures were much better from those reported during the previous period. Moreover, the Yen strengthened during the second week of February, with the yen opening against the dollar at 119.4, and closing at 118.7. The Chinese economy portrayed a rosy picture, and showed that the Central Bank of the country is good at managing the affairs of the country. Consumer Price Index or inflation figures for the month of January showed China was able to keep its prices well in control with inflation clocking in at 0.8% YoY, compared to 1.5% during the previous year. Although MoM inflation remained the same as during the last period at 0.3%, it was still better than broad market expectations of 0.3% ("Economic Calender"). As far as the European Union is concerned, a rough view of the region can be made up by looking at the performance indicators of a few nations within the Union. Germany posted trade surplus for December (with figures being released on 9th Feb) of 21.8bn Euros, amidst market expectations of 18.3bn Euros. The betterment was witnessed on back of 3.4% increase in exports, while imports went down by 0.8%, this widening the balance and resulting in a trade surplus. Though 4Q GDP growth for Germany came in at 1.6% compared to expectations of 1.00%, a deceleration of 0.4% YoY portrayed a worrying picture for the economy. On the other hand, UK’s economy did not perform up to the mark, with industrial production growing not as strong as expected (0.7% vs 0.5%). The BRC Retail Sales Monitor also portrayed signs of worries as sales for January went down 0.2% YoY, amist market expectations of a 5% YoY growth. On an overall basis, the world economy does not seem to be in a very healthy position. With the US jobless claims going up and retail sales going down, it seems that customers lack the purchasing power to be

Use Of Language Learning Strategies English Language Essay

Use Of Language Learning Strategies English Language Essay The concept of language learning strategy use is important in second language acquisition. Since the first studies conducted in the 1970s, many scholars have revealed the complex processes of developing language competency. Many researchers found that language learning strategy use and successful language learners are correlated. Using this concept, some researchers examined the correlation between language learning strategy use and language proficiency in English as a second or foreign language. These outcomes were different depending on other factors such as age, gender, and nationality. This paper will examine what language learning strategies are used by successful language learners. It also will examine what factors affect favorable language learning use. Introduction Language learning strategies are crucial key for learners and teachers to consider in order to develop students language competency. In the classroom, teachers tend to deal with a group of students at one time, but language learning occurs differently in different individuals. Therefore, one learning strategy works for some students, while that learning strategy may not work for other students. Many researchers have tried to reveal what kinds of factors affect the favored language learning strategy use (Cohen, 1998; Cook, 2001; Macao, 2001; Wenden, 1987; OMalley Chamot, 1990; Oxford, 1990). Different factors, such as age, motivation, nationality, gender and so on, are related to different uses of language learning strategies across individual language learners. However, it is important for teachers to pay more attention to creating the learning spaces for any students in the classroom in order to make them successful language learners. Using language learning strategies not only hel ps students learn the language efficiently and effectively, but also helps teachers use the language learning strategies as a tool in the classroom in order to build their language skills. Once students know their preferred language learning strategy, they can apply this to any situations to accelerate their language competency by themselves. Moreover, knowing what strategy works for particular students may give teachers some ideas for the teaching methods or teaching techniques in the classroom for teachers preparation effectively. Therefore, it is important for both students and teachers to examine what kinds of language learning can facilitate effective learning. Literature Review Definition of language learning strategies The term, language learning strategies, has various definitions according to different researchers. Some researchers stated that learning strategies are processes selected by students in order to improve their learning in their own ways (Cohen, 1998; Cook, 2001; Nunan, 1999; Oxford, 1990). The learners decide to choose which learning strategies to use in their learning. Cohen (1998) emphasized that it is important for learners to choose the elements because those things give them their particular preference learning strategies. In support of the definition of learning strategies, Cohen (1998) added that learning strategies can be actions through the storage, retention, recall, and application of information about that language (p.4). The learning strategies are one of the outcomes from using the language. Moreover, OMally Chamot (1990) argued that the learning strategies are the special thoughts or behaviors that individuals use to help them comprehend, learn, or retain new informat ion (p.1). Therefore, the definition of learning strategies focuses learners on how they are able to learn the language consciously and subconsciously. Types of language learning strategy Research on language learning strategy came originally from the field of the cognitive psychology (Mitchell Myles, 2004). In cognitive psychology, some scholars are interested in the information-processing in learners brains with a first or second language use. At the same time, they also were interested in how learners were able to have control over the information by themselves. By knowing the process that learners would take, language educators and researchers have been looking for the effective language learning strategy demanded by ELLs and teachers in order to make them successful language learners. It is important to categorize language learning strategies. At the beginning of the classification of language learning strategies, Rubin (1981) made two categories of language learning strategies. One category is direct learning strategies, such as memorization, monitoring, guessing and so on. The other category is indirect learning strategies, such as creating opportunities for p ractice, using formulaic interaction and so on. In the same vein, Oxford (1990) suggested her own system of language learning strategies. She classified the language learning strategies into two classes and six groups. In the two classes, she used the direct class and indirect class. As for the direct class, the groups are memory strategies, cognitive strategies, and compensation strategies. On the other hand, for the indirect class, the groups are social strategies, affective strategies, and meta-cognitive strategies. This classification provides a comprehensive organization for understanding language learning strategies. Moreover, it is a useful way to analyze language learning strategy use by teachers and learners. In this current study, Oxfords classification system is used in order to determine the language learning strategies. Studies on language learning strategies Researchers and educators started to explore the language learning strategies in the 1970s (Macao, 2001). In the early research about learning strategies, researchers conducted research in the use of language learning strategies in relation to a good language learner. (Macao, 2001; Wenden, 1987). Studies have shown cognitive and meta-cognitive strategies are used the most among all strategies (Green Oxford, 1995; Hong-Nam Leavell, 2006; Rahimi et al, 2008) However, after a few decades, research studies have started to investigate the use of language learning strategies connected to other factors, such as the proficiency of the language, gender, and ethnicity. In in English in the English as Foreign language (EFL) settings, researchers found that successful learners tended to employ language learning strategies more than less successful learners (Green Oxford, 1995; Lai, 2009). In English as a Second Language (ESL) settings, Hong-Nam Leavell (2006) found that students in the intermediate level used the most language learning strategies of the three different English proficiency levels. It is important to see that learners tend to employ the language learning strategies to develop their language learning both in the EFL setting and in the ESL setting. Moreover, learners at different levels of English proficiency have showed their preferable strategies use (Green Oxford, 1995; Lai, 2009; Hong-Nam Leavell, 2006). The more proficient students are, the more they tend to choose meta-cognitive or cognitive strategies to use. On the other hand, the less proficient students are, the more they tend to use social or memory strategies. The profici ency level is related to the choice of learning strategies made by the learners. Other studies focused on the use of language learning strategies in relation to gender (Green Oxford, 1995; Lai, 2009; Hong-Nam Leavell, 2006, Rahimi et al, 2009, Reid, 1987). Many researchers found that women tend to use language learning strategies more than men. However, Rahimi et al. (2009) found that there was no difference of strategy use between genders. One of the reasons for this could be the participants age. Rahimi et al. used post-secondary students as their participants, while other studies used university students as their participants. It is also important to consider the age factor concerning the strategy use. In addition to this, Hong-Nam Leavell (2006) gave the evidence that gender differences affect students preferable language learning strategies differently. Therefore, there may be some relationship between the language learning strategy use and the gender factor. There are also some research studies about the use of language learning strategies in relation to learners ethnic background. Hong-Nam and Leavell (2006) found that most students preferred to use meta-cognitive strategies. On the other hand, Chinese students preferred to use the social strategy. In the same vein, Macaro (2001) found that Italian students reported social strategy use more than English students. However, it is hard to say that there is a particular favored learning strategy use by different learners nationalities. In addition to this, patterns across nationality or ethnicity may be related to different factors like personal characteristics, culture, and received learning strategy use in the class. The purpose of the study The purpose of this current study is to extend the existing literature to investigate the use of language learning strategies for ESL students in the university level in the ESL setting. In this study, participants have already entered the university as undergraduate or graduate students. The study examines what kinds of language learning strategies are most commonly used by the students in order to succeed in academic classes at universities. This study will use multiple variables, such as age, gender, ethnicity, and the English proficiency level, in order to see some relationship between the use of language learning strategies and the other variables. In addition to this, the study will examine how the use of language learning strategies may be related to the length of time in the United States and the length of time studying in the United States. This study tries to answer these questions. What language learning strategies are used by university ESL students in order to succeed in academic classes at the university level? Are there any different uses of language learning strategies between undergraduate students and graduate students? Are these any different uses of language learning strategies between genders? Are there any differences for the language learning strategy use by each nationality? Does the length of time studying in the United States or the length of time in the United States predict the university ESL students language learning strategy use? Methods This current study used mixed methods in order to identify the use of language learning strategies for English as Second Language (ESL) Learners at the university level. Data were collected by using an online survey site. Sample and Site Selection The study involved 300 international students enrolled at University of Nevada, Reno as undergraduate or graduate students. They came from over 30 different countries and they have a variety of majors. The participants are male (160) and female (140). All the participants are only taking academic classes and are full time students with student visa (F-1) status at the University of Nevada, Reno. In order to take only academic classes at University of Nevada, Reno, all international students need to have a score of at least 61 on the Test of English as a Foreign Language (TOEFL) internet based test for both undergraduate and graduate school. In addition to this, they need to pass the bridge test given by the Intensive English Language Center (IELC). If students do not pass the bridge test, they need to take bridge English classes in order to build their English skills. All the participants in this study passed the bridge test or have taken a bridge classes. Additionally, some students recently arrived at the United State to start the school, while some students have been the United States for over five years. The selected site for this study was at the University of Nevada, Reno. It had a total of 553 international students enrolled on the fall 2010. The number consisted of 217 students for undergraduate school and 336 students for graduate school. They came from 66 different countries to study at University of Nevada, Reno. The school offers over 145 degree programs and three different education levels. Instruments In this study, a participants self-reported questionnaire, short answer questions about the use of language learning strategies, and a background information questionnaire were used. For the participants self-reported survey, the Strategy Inventory for Language Learning (SILL version 7.0 for ESL/EFL) developed by Oxford (1990) was used. According to Oxford and Burry-Stack (1995), Cronbachs alpha for the SILL studies has been .85-.95 in order to show the degree of precision on an instrument. These numbers were high, but it showed that the measurement error is minimal (Oxford Burry-Stack, 1995, p.7). The SILL has 50 strategy items and is divided into six categories: Memory strategy, cognitive strategy, compensation strategy, metacognitive strategy, affective strategy and social strategy. The SILL used a 5-point scale for each strategy item ranging from 1, never or almost never true of me to 5, always or almost always true of me. After rating all the items and adding the score for each category, the reporting score can identify which categories of language learning strategies were used the most by each participant. Looking at the results of the scores, there was a basic scale developed by Oxford (1990). The high frequency rate of strategy use was a range from 3.5 to 5. The medium frequency rate was a range from 2.5 to 3.5. The low frequency rate was a range from 2.4 to 1.0 using this scale Additionally, the qualitative questions about the use of language learning strategies were added by the researcher. These questions focused on when to use, and how to use, learning strategies in their academic context, and how they are used differently in English or in their native language. The background information questionnaire was created by the researcher based on an Individual Background Questionnaire (IBQ) developed by Hong-Nan and Leavell (2006). The questionnaire asked for information about age, gender, nationality, native language, the TOEFL score, time of English study, time in the United States, time of schooling, and rate of English proficiency. As instruments for this study, these three different kinds of questions took 40 -50 minutes of the participants time. Data collection and analysis An online survey with all three components of questions was created using Qualtrics Labs, Inc. software, Version 15877 of the Qualtrics Research Suite. Participants were invited by email to complete the online survey at the middle of the semester. They were asked to take the online survey by the end of the semester. In order to increase the rate of their responses on online surveys, email reminders were sent several times. In the email, the researcher explained the purpose of the study and the data collection procedure to the participants and included the URL link for the survey. Their answers in the online survey will remain completely anonymous. The Data analysis has two different parts in this study: the quantitative and the qualitative analysis. In the quantitative analysis, the Strategy Inventory for Language Learning (SILL) and background information were used to calculate the overall strategy use by looking at the computation of descriptive statistics in order to know which language learning strategies were used most commonly. ANOVA analysis was used in order to find out whether there were any differences between the use of language learning strategies and the other factors . The independent variables were these factors such as, such as age, gender, nationalities, the educational levels, the time spent the United States, and the time studying in the United States, while the dependent variable was the use of language learning strategies. In the qualitative analysis, the short answer questions in the online survey were used in order to support recurrent themes for quantitative analysis. Appendix A. Short answer questionnaire.

Humanities - The Heart of Liberal Education Essay -- Education Philoso

I justify the humanities by sketching four views of knowledge in which the idea of an academy or an integration of disciplines might be understood. I assume that every system of higher education inevitably appeals to concepts of knowledge. Such concepts cannot be isolated from political and civic dimensions of life as well as from personal cultivation and character. Nonetheless, older views based on these aspects are open to serious criticism. The four views considered are Aristotelian-Thomistic, Cartesian-positivist, Kantian, and "traditionalist" (in a liberal and hermeneutic sense). The paper describes key elements in each of these views and notes several objections, with a marked preference for Kantian and "traditionalist" views. Kant provides for rehabilitation of the humanities, especially ethics and literature (the moral and aesthetic), within a framework in which modern science displaces ancient teleological nature. "Tradition" is justified on practical grounds--by the need to appropriate for oneself the knowledge and experience of past generations (without which human life loses continuity and meaning). Further, the humanities save the great texts from oblivion to which "progress" would otherwise consign them. The humanities counteract the tendency of science to undermine the conditions of its own possibility, as well as the discipline, knowledge, and virtue required for its own origin. Two questions are urgently posed to the modern academy: what is the justification for congregating all the disciplines of modern knowledge under one roof as if they belonged integrally together—if, that is, there is one? For perhaps it is merely a convenience. And secondly, what is the justification—if there is any—for insisting upon th... ...ndered unnecessary by its existence. Technology makes perpetual adolescents of us, because of the ease with which it puts great power in our hands; its power diminishes our desire (and thus our capacity) for responsibility. In the face of this fact of modern life, the traditionalist view of education seeks to reverse this effect, without denying the legitimacy of science. It cultivates liberal virtues by keeping the classics and all the great texts alive, including the classics of science itself (physical and human), abandoned by later science. Traditional stances like those of (1), (2), and (3), may be suspicious of it because it declines the attempt to found education upon the dogma of a metaphysics or an epistemology. But it may well be the most practical way pedagogically that the aims and content of those approaches can be sustained within a modern environment.

Ender Book Report Compassion vs Ruthlessness Essay

In the novel Ender’s game, Orson Scott Card attempts to convey the message of the conflict between compassion and ruthlessness. For one thing Ender often compares himself to his ruthless brother Peter every time he himself does something mean and cold hearted. But Ender also has a compassionate personality. he shows his compassionate personality in many cases. He also shows that Ender may have a bit of a ruthlessness in him, but resents himself for it. He then also shows that compassion beats ruthlessness when Enders overtops ruthless Peter in almost everything they do. Therefore Orson used the theme compassionate vs. ruthlessness by exhibiting Ender’s success and Peter’s failures to exhibit the theme compassion vs. ruthlessness. Peter has more of an influence in Ender’s life then he realized, He even acknowledges it one point when thanks Peter in his mind for teaching him how to hide his feelings. Often Ender compares himself to Peter especially when he ends up hurting or killing something or someone. After he beats up Stilson. He thinks that he’s like Peter. â€Å"Ender leaned against the wall of the corridor and cried until the bus came. ‘I am just like Peter. Take my monitor away and I’m just like Peter. ‘† (page 8) Ender realizes with anguish that he’s turning into Peter. He finds this really sad. Another time he feels like Peter is when is when he’s flying to battle school. On the way there, a boy kept harassing him. Ender then proceeds to harm the boy and break his arm. â€Å"Just as the next blow was coming, Ender reached up with both hands, snatched the boy by the wrist, and pulled down on the arm, hard†¦ I am Peter. I am just like him. And Ender hated himself. † (page 122) Ender, even though he was defending himself, broke a kid’s hand and compared himself to Peter. He also hated himself for it. At one point, after Ender see’s a reflection of Peter staring at him on a mirror in a reality game that shows your perspective of reality, the teacher’s acknowledge it. â€Å"‘But why. His brother is dangerous, his bother was rejected for the program because he’s one of the most ruthless human beings we ever laid hand on. Why is he so important to Ender? why after all this time? ‘† (page 122) Peter is clearly important to Ender because Ender always keeps comparing himself to him, bares such a resemblance, and resents Peter, and himself. In conclusion Peter had a major influence in Ender’s life, in a sense of a bad role model, in Ender’s mind. Ender, all though often comparing himself to ruthless Peter, was actually very compassionate in many senses. When fellow student, and victim Shen is being bullied by Bernard, Ender interferes. Ender makes Bernard look stupid by sending stupid messages in Bernard’s name to make Bernard look stupid and make Shen happy † Cover your butt. Bernard is watching -God. Bernard went red with anger. ‘ Who did this! ‘ he shouted ‘God, ‘ said Shen. (page 50) Ender shows compassion by making Shen have a little bit of a victory, and making Bernard look plain stupid. Also, at one point Ender, when Bonzo and Ender are having an argument, Ender shows some kindness. â€Å"‘But if you want, I’ll pretend that you won this argument. Then tomorrow you can tell me you changed your mind’ ‘I don’t need you to tell me what to do. ‘ ‘I just don’t want the other guys to think you backed down. Then tomorrow you can tell me you changed your mind. ‘ Bonzo hated him for it, for the kindness. Ender tried to understand why. † (page 87) Ender shows kindness, even to Bonzo who his giving him a hard time. He makes sure that Ender wins the argument yet making Bonzo not look foolish in front of his boys. This shows many characteristics including kindness, compassionate, and also leniency. Also Ender shows compassion when he continued to train with the launchies (basically a group of kids that are new to the battle school. Ender was one of them but Ender quickly advanced ahead of his class. ) â€Å"‘Now your really in an army. ‘ said Alai ‘You don’t need have to keep practicing with us. ‘ ‘From you I can learn things nobody knows,’ said Ender ‘Dink Meekr is the best. I hear he’s your toon leader. ‘ ‘ Then let’s get busy. I’ll teach you from what I learnt today. ‘† (page 103) Even when Ender is finally part of an army that actually uses him, he is still trained with the launchies, his former friends. He did not forsake them and showed many attributes such as caring, compassion, and kindness. In conclusion even though Ender may have a bit of Peter’s influenced ruthlessness he is still very kind and compassionate. Compassion is shown to top ruthlessness when Ender succeeds in achieving in everything that Peter failed in. Ender is first more successful then Peter when he keeps his monitor longer then Peter. â€Å"But Peter would not soothed. ‘Like us? He keeps the little sucker till he’s six years old. When did you lose yours? You were three. I lost mind before I was five. He almost made it, little bastard, little bugger. ‘† (page 10) Ender kept his monitor longer then Peter. Peter noticed this and pretty much snapped at his brother. This shows that Peter was both mad and jealous. The second time when he overtops Peter is when Ender is invited personally to battle school by Colonel Graff â€Å"‘My name is Graff Ender. Colonel Hyrum Graff. I’m director of the primary training at the battle school in the Belt. I’ve come to invite you to enter the school. ‘† (page 19) The director of the battle school came himself to invite Ender to the battle school, which is a rare honour which most boys, including Peter always wanted; to go to battle school and learn how to fight the buggers. The final time when final major accomplishment is when he defeats the buggers. â€Å"‘ Ender, for the past few months you have been battle commander of our entire fleet. This was the third invasion. There was no games, the battles were real, and the only enemy you fought was the buggers. You won every battle and today you finally fought them at their home world, where the queen was, all the queens from all their colonies. They all were there and you destroyed them completely, They’ll never attack us again. You did it. You'† ( 296-297) Ender was able to defeat the buggers, and win a whole entire war single handily He achieved every boy’s dream, to beat the buggers and save mankind. In conclusion Ender prevailed over ruthless Peter, which made him more successful then Peter. In conclusion Orson exhibits the them Compassion vs Ruthlessness by exhibiting the success of Ender and the failure of Peter. He shows this by comparing Ender to Peter and making Ender hate himself for it. But also exhibiting Ender’s overwhelming compassion to his other students. He also shows this by most importantly compassionate Ender vs ruthless Peter and how Ender overtopped him in everything he (Peter) did. Ender succeeded in everything Peter wanted to do. Even if though you need ruthlessness to do something dreadful, if you have enough compassion, you win out in the end.

5 Important Oedipus Rex Quotes Explained

5 Important Oedipus Rex Quotes Explained Oedipus Rex  (Oedipus the King) is a famous play by the great ancient Greek tragedian  Sophocles. The play was first performed around 429 BCE and is part of a trilogy of plays which also include Antigone and Oedipus at Colonus. In a nutshell, the play tells the story of Oedipus, a man doomed from birth as a result of a prophecy which states that he will murder his father and marry his mother. Despite his familys attempts to stop the prophecy from being fulfilled, Oedipus still falls prey to fate. The simple plot of the play can be easily summed up in just five key quotes. Oedipus Rex has influenced artists and thinkers around the world for more than two millennia. Its the basis for  Sigmund Freuds psychoanalytical theory, appropriately named the Oedipus complex; as Freud notes of Oedipus in his seminal work The Interpretation of Dreams: His destiny moves us only because it might have been ours- because the oracle laid the same curse upon us before our birth as upon him. It is the fate of all of us, perhaps, to direct our first sexual impulse towards our mother and our first hatred and our first murderous wish against our father. Our dreams convince us that this is so. Setting the Scene Ah! my poor children, known, ah, known too well,The quest that brings you hither and your need.Ye sicken all, well wot I, yet my pain,How great soever yours, outtops it all. Oedipus exclaims these sympathetic words at the beginning of the play to the people of Thebes. The city is beset with a plague and many of Oedipuss citizens are sick and dying. These words paint Oedipus as a compassionate and empathetic ruler. This image, juxtaposed with Oedipuss dark and twisted past, revealed later in the play, makes his downfall even more striking. Greek audiences at the time were already familiar with the story of Oedipus; thus Sophocles skillfully added these lines for dramatic irony. Oedipus Reveals His Paranoia and Hubris The trusty Creon, my familiar friend,Hath lain in wait to oust me and subornedThis mountebank, this juggling charlatan,This tricksy beggar-priest, for gain aloneKeen-eyed, but in his proper art stone-blind.Say, sirrah, hast thou ever proved thyselfA prophet? When the riddling Sphinx was hereWhy hadst thou no deliverance for this folk?And yet the riddle was not to be solvedBy guess-work but required the prophets artWherein thou wast found lacking; neither birds nor sign from heaven helped thee, but I came.The simple Oedipus; I stopped her mouth. This speech by Oedipus reveals a lot about his personality. A clear contrast from the first quote, Oedipus tone here shows that he is paranoid, has a short temper, and is pompous. Whats happening is that Teiresias, a prophet, refuses to tell Oedipus who the murderer of King Laius (Oedipuss father) is. A bewildered Oedipus reacts by angrily taunting Teiresias for being stone-blind, a charlatan, a beggar-priest, and so on. He also accuses Creon, the person who brought Teiresias, for planning this perplexing scene in an attempt to undermine Oedipus. He then continues to belittle Teiresias by saying how useless the old prophet, as it was Oedipus who defeated the Sphinx who terrorized the city.   Teiresias Reveals the Truth Of the children, inmates of his home,He shall be proved the brother and the sire,Of her who bare him son and husband both,Co-partner, and assassin of his sire. Provoked by Oedipuss offensive words, Teiresias finally hints at the truth. He reveals that not only is Oedipus the murderer of Laius, but he is both brother and [father] to his children, both son and husband to his wife, and the assassin of his [father]. This is the first piece of information Oedipus gets in discovering how he unwittingly committed incest and patricide. A humbling lesson- Sophocles shows how Oedipus hot temper and hubris provoked Teiresias and set his own downfall in motion.    Oedipus Tragic Downfall Dark, dark! The horror of darkness, like a shroud,Wraps me and bears me on through mist and cloud.Ah me, ah me! What spasms athwart me shoot,What pangs of agonizing memory? In a grotesque scene, Oedipus screams these lines after he blinds himself. At this point, Oedipus has realized that he indeed killed his father and slept with his mother. He is unable to cope with the truth after he has been blind to it for so long, and so symbolically blinds himself physically. Now, all Oedipus can see is darkness, like a shroud. The Conclusion of One Story and Beginning of the Next Though I cannot behold you, I must weepIn thinking of the evil days to come,The slights and wrongs that men will put upon you.Whereer ye go to feast or festival,No merrymaking will it prove  for you Oedipus utters these words to his daughters, Antigone and Ismene, at the end of the play before being cast out of the city. The introduction of these two characters foreshadows the plot  of another famous play by Sophocles, Antigone.

Free Essays on John Donne

Death, commonly viewed as an all-powerful force against life, is otherwise described in John Donne’s Holy Sonnet 10. As found in any English Sonnet, there is a rhyme scheme and a standard meter. Although the standard meter is iambic pentameter, as in most English Sonnets, the rhyme scheme differs a little from the usual, consisting of ABBA ABBA CDDC AE. Sonnets convey various thoughts and feelings to the reader through the different moods set by the author. In this case the speaker having to confront Death and defeat it, sets the mood. Throughout existence, there have been many theories regarding exactly what role Death plays in the lives of those who experience it. Some think Death is the ultimate controller of all living things, while others believe it is nothing more than the act of dying once your time has come. Donne, on the other hand, has his own philosophy. The entire Sonnet, Donne speaks directly to Death.

Mesopotamia Creation Stories Essay Example | Topics and Well Written Essays - 2500 words

Mesopotamia Creation Stories - Essay Example This is because a text's genre serves to channel writers and readers by providing a common ground to determine the production and interpretation of specific texts. Biblical and Mesopotamian creation stories are linguistically, culturally, and historically very different from modern day ways of thinking, experiencing and interpreting the world. So as to correctly as possible interpret the writings of Genesis it is necessary to school oneself in other Near Eastern creation stories. The present paper will compare and contrast Mesopotamian creation stories with that of the Bible. Firstly, the creation story, "Epic of Creation" will be used to develop the Mesopotamian interpretation of how the cosmos and humankind came to be. Secondly, the Biblical interpretation of creation of this universe and humans will be presented. Next, issues of translation will be addressed. Finally, a conclusion shall synthesize the main arguments of the paper, and demonstrate the critical need for comparative analysis of creation stories in the Near East. The Mesopotamian myth of creation is quite violent, especially with regard to later civilizations, such as Egypt, and the later Biblical Creation Story. ... In turn these serpents produced Anshar, the heavens, and Kishar, the earthly world. And from these two came the great gods, Anu, Enlil, and Ea, as well as the other gods of the sky, earth, and the underworld. Many of these new gods were noisy, which upset Apsu and Tiamat, since they could not rest. These primordial goddesses then discussed whether they should annihilate their progeny. When Ea, the all-knowing, learned of Apsu's plan to destroy the gods he used his magic to capture her and Mummu. Tiamat was furious and created a monstrous army of gods and freak creatures to punish Ea and his cohorts. Ea went to his father Anshar, and Anshar advised him to send Anu to fight Tiamat. But both Anu and Ea were afraid of the goddess and her army. Then Ea called Marduk forth. Marduk promised to conquer Tiamat if he were given supreme authority over the gods. The gods agreed that he was to have lordship scepter, the throne, and an invincible weapon. Armed with bow and arrows, lightning, the winds, a hurricane, and a special net, Marduk rode forth to meet Tiamat in his chariot, which was a tempest, drawn by four fearsome steeds. They clashed and Marduk caught Tiamat in his net. When she opened her mouth to swallow him, Marduk let loose the hurricane, which filled her jaws and belly, thereby stunning her. The Marduk shot an arrow into her belly and killed her. Tiamat's army fled in confusion at her downfall, but Marduk caught them in his net, chained them, and cast them into the underworld. As he was cutting up Tiamat's body, Marduk conceived a plan. From one half he made the dome of the heavens, and with the other half he made the earth. He

Psychological Survival - Cohen and Taylor Essay Example for Free

Psychological Survival Cohen and Taylor Essay 1) Aim of the study Obtain a phenomenological picture of long term imprisonment i.e. the analysis of the every day life of long term prisoners. The smooth patterning of every day life is the result of social interactions and learning about routines and the different domains of life. But some situations are outside the routines (death, sense of self or world view threatened). Disturbed orderliness brings meaning of life into question and often individuals rely on a different domain. Long term prisoners cannot do this. Theirs is a life in cold storage. Psychologically hard to deal with life outside. Some people go in when 20 and don’t leave before they’re 40, so a lot has gone on in everyday life and they’ve missed it. 2) Cohen and Taylor not really interested in the crime committed and the moral issues behind it. They are just interested in how prison affects this group of people. Society has been taken away from these people. Some of the people are well known, but they put aside what these people have been convicted on, they just want to know about their psychological survival. 3) Life inside Metaphor of a submarine: Impregnability, empty, claustrophobic, lifeless, bland no natural light, TV cameras. Things we take for granted in normal life, sociability and privacy, are not there. Not many friends you can have or choose to have. Relationships between guards and prisoners, maybe from a similar social backgrounds, have a lot to talk about. In the E-wing case there was a very pronounced geographical divide, north and south. Prisoners have a public profile outside, quite famous and it sets them aside from the guards. A sense of celebrity in some of the prisoners. This creates a division between guards and prisoners. New power dynamic. Not only hard to create and maintain relationships inside hard to do so with the external world. The prisoners were more worried about getting letters rather than receiving them. No physical contact, e.g. members of your family. Not allowed to talk about conditions in the prison maybe that is why they wanted to get their stories heard with Cohen and Taylor. Isolating experience. 5) different people fulfil different social roles. Obviously there was a small pool in prison. One friend had to fulfil many different roles, which made friendship very strong and intense. Some people were moved constantly and losing your one friend can be traumatic. Intensity of relationships and falling out, which will have an impact on the group and on you. No privacy no time. Can’t develop intimacy with other people. Constantly surrounded by others. Interactions regulated within the group to make sure nobody got harmed. 6) time means different things. For us it’s a resource. Living the present they don’t face or think of the 20 years ahead. Marking time in different ways: mood, seasons, unusual markers. Make time pass faster: body building, university courses, etc. promise of a visit. 8 weeks visit for e.g. 7) deterioration obsessive concern about their physical and psychological condition. 8) history of riots, rebellions and security. Cohen and Taylor interested in solidarity. The resentment towards guards held the group together, helped with bonding. Fight back together. 9) authority and unity different situations lead to different types of solidarity 10) fighting back 11) different criminal careers lead to different ways of psychological survival. Notes from a lecture and seminar on Psychological Survival.

Endosymbiotic Theory in Eukaryotic Cells

Endosymbiotic Theory in Eukaryotic Cells Endosymbiotic theory- the modern, or organelle- containing eukaryotic cell evolved in steps through the stable incorporation of chemoorganotrophic and phototrophic symbionts from the domain Bacteria. The hypothesis of endosymbiosis is at present the most widely accepted theory on the evolution of the eukaryotic cell. This current theory states that the mitochondria and chloroplasts contained within the eukaryotic cell, are there due to the integration of free living bacteria which implement aerobic metabolism, chemoorganotrophic bacteria, and bacteria which implement oxygenic photosynthesis, cyanobacteria. It is thought that symbiosis, in addition to natural selection and mutations, is also a driving force in the evolution of the modern or organelle containing eukaryotic cell. This essay will describe in detail the endosymbiotic theory and its features, discuss the evidence which supports it and then discuss its major opposing theories, the hydrogen hypothesis and the syntrophy hypothesis. Short history of the endosymbiotic theory Many biologists have had a role in what is now known as the endosymbiotic theory. Firstly in 1883, Andreas Schimper proposed that particular organelles evolved from the symbiotic union of two different organisms, (this was while he was studying chloroplast division within green plants and observed a similarity between chloroplasts and free living cyanobacteria.), (Vargas-Parada, 2010). In 1905, Konstantin Merezhkovski devised the term, symbiogenesis , due to his work on lichens leading him to speculate that more complex cells evolved from a symbiotic relationship between less complex ones (2006). Then in the 1920s, Ivan Wallin suggested that organelles such as mitochondria and chloroplasts began as symbiotic bacteria and that species creation could have occurred through endosymbiosis. Finally, much later in 1967 Lynn Margulis collected various microbiological observations which supported the hypothesis of endosymbiosis. Evolution of the eukaryotic cell The current evidence for the evolution of eukaryotic cells suggests that around 4 billion years ago ancestors of Bacteria and Archea arose. It is thought that in bacteria, around 3.2 billion years ago, phototrophy occurred, with the common ancestor of many bacteria thought to be an anaerobic phototroph. Then around 2.7 billion years ago oxygen-generating cyanobacteria developed, which over time caused an increase in the atmospheric oxygen levels. The atmosphere slowly changed from anoxic to oxic due to this rise in oxygen levels. At some point during this period eukaryotic microorganisms containing organelles evolved and the oxic environment drove their evolution. Main distinguishable features of present day eukaryotes from prokaryotes In many prokaryotic cells their DNA is arranged into a single loop, is circular and unlike eukaryotes, it is not associated with histones and is therefore termed naked. Prokaryotic cells reproduce by the process of binary fission, are mainly unicellular organisms and are usually smaller than eukaryotic cells. In the nucleus of the eukaryotic cell, the DNA is organised into chromosomes, which is surrounded by a membrane. Eukaryotic cells reproduce by the means of mitosis and meiosis, are usually larger than prokaryotic cells and are usually complex and multicellular. The main distinguishing feature of eukaryotic cells is that they contain membrane bound organelles, with the most noteworthy being the mitochondria and chloroplasts. The major organelles involved in the endosymbiotic theory The endosymbiotic theory refers to the organelles mitochondria and plastids, (plastids refer to chloroplasts, chromoplasts, and gerontoplasts, to name a few), however mainly focuses on chloroplasts. The major reason for these two organelles being involved in the endosymbiotic theory is because they both contain a small genome. Moreover, both of these organelles contain the operating systems required for cellular functions such as protein synthesis, for example ribosomes and transfer RNA, and also the cellular constituents needed for translation. Mitochondria Mitochondria are the site of respiration and oxidative phosphorylation in eukaryotic cells. They are membrane bound organelles, with each cell containing thousands of them. Mitochondria show variations in their morphology, and can be rod-shaped or spherical. They are surrounded by two membranes, an outer membrane and an inner membrane. The outer membrane is made up of protein and lipid and contains channels which allow the diffusion of ions and small organic molecules. The inner membrane is less permeable and is invaginated to form cristae. Oxidative phosphorylation occurs on the inner membrane; with cristae allowing maximum surface area for ATP synthase molecules, which are involved in the synthesis of ATP (Adenosine Triphosphate), the final step of oxidative phosphorylation. It is for this reason that they are considered to be the power generators of the cell. Mitochondria possess their own DNA which is independent of the cells chromosomal DNA. The mitochondrial genome mainly encodes proteins needed for oxidative phosphorylation and also encodes ribosomal RNAs, (rRNAs), transfer RNAs, (tRNAs) and proteins necessary for protein synthesis. Mitochondria use simplified genetic codes, which seem to have arisen from selection pressure for smaller genomes (Madigan, 2009 p. 351). Even though mitochondria possess their own genome they still require proteins encoded by nuclear genes. Chloroplasts Chloroplasts are membrane bound organelles found in phototrophic eukaryotic cells. These cells are found in plants algae and some protists. Chloroplasts contain chlorophyll which is the photosynthetic pigment present within them. Chloroplasts are usually larger than bacterial cells and can differ in size and shape. Chloroplasts again like mitochondria consist of two membranes and inner membrane and an outer membrane. Their outer membrane is permeable and the inner membrane is less permeable. The inner membrane surrounds the stroma, which houses the photosynthetic pigment, chlorophyll and other cellular components needed for the process of photosynthesis in thylakoids. Thylakoids stacked into the structural units, grana. The thylakoid membrane is not permeable to ions and other metabolites, due to the light reactions of photosynthesis needing the proton motive force which is necessary for the synthesis and release of ATP. The stroma of the chloroplast holds large amounts of the enzyme RubisCO, (ribulose bisphosphate carboxylate), which catalyses the Calvin cycle or the dark reactions of photosynthesis. The Calvin cycle converts COà ¢Ã¢â‚¬Å¡Ã¢â‚¬Å¡ into various organic compounds like glucose which are needed by cells. Chloroplasts also contain their own DNA, which is also independent of the cells chromosomal DNA. The identified chloroplast genomes are all circular DNA molecules, with each chloroplast containing several matching copies of the genome (Madigan, 2009 p. 350). Genes contained within the chloroplast encode for proteins required for photosynthesis and autotrophy to occur and also rRNA and tRNA used for the processes of transcription and translation. Like mitochondria, chloroplasts have some proteins, which are encoded by nuclear genes and not just by the chloroplast genome. Introduction to the endosymbiotic theory The primary endosymbiotic theory implies that the mitochondrial ancestor was a free living facultatively aerobic alphaproteobacterium, attained by another cell and therefore giving rise to a eukaryotic cell. (Madigan, 2009 p. 520) A species of cyanobacterium is thought to be the ancestor of chloroplasts, obtained by a heterotrophic eukaryote, after eukaryotic cells had appeared around 1.5 billion years ago (Madigan, 2009 p. 520) and was obtained as an internal symbiont (Bruce Alberts, 2002). Secondary endosymbiosis refers to the event where several non-phototrophic organisms attained chloroplasts, after the primary endosymbiosis event is said to have occurred. Secondary endosymbiosis is said to have been an important factor in the evolution of eukaryotes, bringing the modern diversity of life into being (Macfadden, 2001). Features of and molecular evidence for the primary endosymbiotic theory The main point of the primary endosymbiotic theory, and which gives it its credibility, was that both mitochondria and chloroplasts both contain DNA, with rRNA, tRNA and proteins involved and needed for the respiratory chain in mitochondria and proteins needed for photosynthesis in chloroplasts, being encoded by these small genomes within mitochondria and chloroplasts. Non-phototrophic eukaryotic cells are genetic chimeras containing DNA from two different sources, the endosymbiont, which is the mitochondria, and the host cell nucleus (Madigan, 2009 p. 520). Eukaryotes which are phototrophic, for example algae and plants, have DNA from two endosymbionts, the mitochondira and the chloroplasts as well as the nuclear DNA. The majority of mitochondrial DNA and chloroplast DNA is similar to bacterial DNA in its shape, which is circular and size. The second feature of primary endosymbiosis is that genes originating from bacteria are found in the nucleus of the eukaryotic cell. This has been proven by sequencing genomes, which have shown that nuclear genes encode properties unique to mitochondria and chloroplasts, (and also which closely resemble genes of bacteria), showing that during the evolution of the eukaryotic cell these genes where transferred to the nucleus of the eukaryotic cell, from the bacterial endosymbionts, during the development of the organelle from the engulfed cell (Madigan, 2009 p. 521). The third feature of primary endosymbiosis is that the mitochondria and chloroplasts contain their own ribosomes. Ribosomes are present in eukaryotic cells and prokaryotic cells, with eukaryotic cells possessing the larger form, 80S, and prokaryotic cells containing the smaller, 70S, ribosomes. The mitochondria and chloroplast contain these 70S ribosomes. The fourth feature is antibiotic specificity. Mitochondria and chloroplast are sensitive to antibiotics which kill bacteria or are bacterial inhibitors. Some for example streptomycin do this by specifically interfering with the functions of the 70S ribosomes, which occurs in the same way in mitochondria and chloroplasts (Madigan, 2009 p. 521). Rifampicin is an antibiotic which in bacteria affects the RNA polymerase. It does not have this effect on eukaryotic RNA polymerase however does inhibit mitochondrial RNA polymerase. The fifth and final feature of primary endosymbiosis is that of molecular phylogeny. Phylogenetic studies comparing organelles and rRNA support the theory of mitochondria and chloroplasts deriving from bacteria. There is also other evidence in addition to what is mentioned above. Both mitochondria and chloroplast are surrounded by two membranes. It is though that the inner membrane is the original membrane which contained the prokaryotic cell and the outer membrane results from the process of endocytosis when the bacteria were taken into the eukaryotic cell. Protein synthesis in the endosymbionts begins with N- formyl methionine, the same amino acid that initiates protein synthesis in bacteria whilst in eukaryotic cells protein synthesis is initiated by methionine. Also the thylakoid membrane and the protein complexes which it contains are like those that can be found in cyanobacteria (Pyke p. 5) , and chloroplasts can divide in a way which is similar to the process of binary fission which is carried out by bacteria. This evidence all suggests that the host cell which obtained the mitochondrion by phagocytosis was an anaerobic eukaryotic cell, (which already contained a nucleus) and that the mitochondrial endosymbiont was an obligate anaerobe (Mentel, 2010). This event was later followed by the endosymbiosis of a cyanobacterium, allowing the eukaryotic cell to become photosynthetic. In this way the host eukaryotic cell attained permanent organelles which are suited to energy production. It was also mutually beneficial for the symbionts which obtained a constant and accommodating environment for their growth. Secondary endosymbiosis The primary endosymbiosis event in the common ancestor plants and in green and red algae is said to have created the modern day chloroplast. The secondary symbiotic event refers to non-phototrophic eukaryotes obtaining chloroplasts by the endocytosis of a green or red algal cell and consequently becoming phototrophic. It is thought that secondary and even further endosymbiosies lead to the diversification of eukaryotes. Problems with the endosymbiotic theory To support the endosymbiotic theory in the 1980s, Tom Cavalier-Smith proposed that certain single-celled eukaryotes which are at present still living, bear a resemblance to earlier eukaryotes, were primitively amitochondriate (Lane, 2005 p. 42),(basically eukaryotes without any mitochondria), and Cavalier-Smith named them archezoa. (He later abandoned this theory in 2002, (Cavalier-Smith, 2002)) These cells derived their energy via fermentation and prefer environments with little oxygen and were thought to be the bridge between early eukaryotic cells (as archezoa contain a nucleus) and prokaryotic cells, which would have supported the theory of a bacterial cell being phagocytised, but not digested, leading to the possession of a mitochondria in the early eukaryotic cell. It was then thought that as oxygen levels on earth started to rise, the mitochondria too, began to evolve, due to aerobic respiration being more resourceful than anaerobic respiration, which again supported that the phagocytosis of this bacterial cell was for the purpose of a more efficient way of generating energy. In March 2000, Jan and Siv Andersson proposed the Ox-Tox hypothesis to explain that aerobic respiration was the selective pressure leading to the gain of the mitochondria, originally selected for the removal of oxygen by the host cell (Andersson, 2000). This was due to research showing that the genome sequence of Rickettsia prowazekii had a strong phylogenetic relationship with mitochondrial proteins (Andersson, 2000). However in the late 1990s these hypotheses were question due to the appearance of contradictive evidence. The genomes of archezoa were sequenced and genes were found which showed that the ancestors of archezoa once had mitochondria, even though there was no physical indication of them in the cell. Some archezoa such as Giardia were found to have mitochondria but in the form of mitosomes, which still carried out mitochondrial processes (Lane, 2005 p. 47) again implying that these eukaryotes once contained mitochondria within their cells. It was then suggested that the original host in the eukaryotic merger was a methanogen, due to the structure of eukaryotic and methanogenic histones and the 3D conformation of the DNA associated with the histones being closely related (Lane, 2005 p. 48). Other problems with the endosymbiotic theory are that if a bacterium was phagocytised by a eukaryotic cell, it would definitely have been digested and neither mitochondria nor chloroplasts are able to survive independently outside of the eukaryotic cell. Chloroplasts arent the main focus when disproving the endosymbiotic theory as its thought that when the phagocytosis of a phototrophic symbiont occurred, the host cell already contained mitochondria. The alternative theories to the mainstream endosymbiotic theory The hydrogen hypothesis In 1998, William Martin and Miklà ³s Mà ¼ller proposed the hydrogen hypothesis. Unlike other hypotheses which suggested that the formation of eukaryotic cell was due to the rising oxygen levels, this hypothesis suggests that instead it was to do with hydrogen. They state that Eukaryotes are suggested to have arisen through symbiotic association of an anaerobic, strictly hydrogen dependent, strictly autotrophic archaebacterium (the host) with a eubacterium (the symbiont) that was able to respire, but generated molecular hydrogen as a waste product of anaerobic heterotrophic metabolism. (Mà ¼ller, 1998). The hydrogen hypothesis is based on hydrogenosomes which are anaerobic mitochondria, that produce ATP and with their waste products including hydrogen gas and carbon dioxide and which also are able to function in low oxygen environments. Martin and Mà ¼ller suggested that there was a methanogenic ancestry of the host (Mà ¼ller, 1998) due to methanogens needed the very products (hy drogen and carbon dioxide), which are released by hydrogenosomes and because hydrogenosomes survive in the same environment as methanogens. Due to the intimate association between the methanogen and the bacterium, the symbiosis becomes closer, due to the methanogen needing the products of respiration produced by the bacteria and it is gradually engulfed by the methanogen. By the process of lateral gene transfer from bacterium to methanogen, the methanogen is now able to carry out aerobic and anaerobic respiration (Lane, 2005). There are known examples today of bacteria which live as endosymbionts within other prokaryotes (Mentel, 2010), which again helps support this hypothesis. Another point which gives the hydrogen hypothesis credibility is that all anaerobic and aerobic mitochondria all originated from a facultatively anaerobic ancestral state (Mentel, 2010). Also according to the hydrogen hypothesis, the host cell was not required to have possessed a nucleus (Mà ¼ller, 1998). The formation of the nucleus is explained by genes for the synthesis of lipids being transferred to the host chromosome from the symbiont leading to the host synthesising these bacterial lipids and then resulting in the formation of the endoplasmic reticulum, an internal membrane system and origination of a eukaryotic nucleus (Madigan, 2009 p. 376). The effects of the hydrogen hypothesis for chloroplasts have not been considered in much depth (Allen, 2003). The syntrophy hypothesis This hypothesis was proposed by Purificacià ³n Là ³pez-Garcà ­a and David Moreira in 1999. This hypothesis is based on similar metabolic considerations as the hydrogen hypothesis proposed by Martin and Mà ¼ller (Moreira, 1999). There are some similarities between the two hypotheses. Firstly, they both maintain that the metabolic nature if the original symbiotic event involved both hydrogen and syntrophy, secondly that the hydrogen dependent autotrophic archeon must have been a methanogen (Moreira, 1999) and finally that the mosaic nature of the eukaryotic genome can be explained by lateral gene transfer and replacement over a long symbiotic life (Moreira, 1999). The difference between these hypotheses is that the syntrophy hypothesis states that the organisms involved were ÃŽÂ ´- proteobacteria, which are ancestral sulphate reducing myxobacteria, and methanogenic archaea (Moreira, 1999). The hydrogen hypothesis states that an ÃŽÂ ±-proteobacteria began the symbiosis, wherea s in the syntrophy proposal it is thought that two eubacterial types were involve, a sulphate reducing ÃŽÂ ´- proteobacteria, (which produced hydrogen for fermentation), and also an ÃŽÂ ±-proteobacterial methanotroph became symbionts and used the methane which was generated by the methanogen to produce C0à ¢Ã¢â‚¬Å¡Ã¢â‚¬Å¡. Both of these hypotheses agree that the ancestral mitochondria were of anaerobic origin (Moreira, 1999). The chimeric nature of the eukaryotic cell The hypotheses mentioned above, suggest that the modern eukaryotic cell is a chimera, which is a cell that is made up of features from both Bacteria and Archaea (Madigan, 2009 p. 376). Eukaryotes contain the same sort of lipids which are found in Bacteria and the tools they contain for transcription and translation are like those found in Archaea (Madigan, 2009 p. 376). The chimeric nature of nuclear genomes can be partially explained by the endosymbiont hypothesis of mitochondria (Hua). At some stage in eukaryogenesis, cellular and genomic combination of the two different organisms (which vary for the hydrogen and syntrophy hypothesis) happened with gene transfer from bacteria to archaea and then subsequent replacement. The bacterial genome is then thought to have condensed down and could have also dematerialised as the cell underwent evolution, (as horizontal gene transfer, which includes the introduction and loss of genes, is often seen in symbionts (Madigan, 2009 p. 377)). The de veloping eukaryotic cell must have inherited some of the archaeal-DNA processing systems, whereas the cellular metabolism systems are thought to have come from bacterial organotrophy (Hua). During its evolution the modern day eukaryotic cell has become ever more complicated and has led to the appearance of complex, multicellular life forms which are powered by mitochondria and chloroplasts in phototrophic eukaryotic cells. The progression of its evolution and how all the individual compartments of the cell occurred is expected to have taken an extensive amount of time. Variation and natural selection evidently occurred, perfecting the cell by the removal of mechanisms and cellular structures which were deemed useless, leading to biological diversity. It is still undetermined which of these hypotheses mentioned accurately describe the origin of eukaryotes and is thought that the further sequencing of genomes and phylogenetic analyses of the prokaryotic and eukaryotic genomes will provide an improved elucidation of the origin and diversity of eukaryotes.
