Comparative Essay The Secret Life of Walter Mitty Essay

Any movie based upon a piece of literature can make or break its source of inspiration. Some movies do no mercy toward the book, while some exceed the quality of the novel. The movie, The Secret Life of Walter Mitty, directed by Norman Mc Lean, was a much better piece of work than the short story, â€Å"The Secret Life of Walter Mitty,† written by James Thuber, because the video had a satisfying conclusion, more action, and a much more developed and advanced plot. The conclusion of the story left you unsatisfied and discontent because it didn’t really tell you what happens to the protagonist; it just ends, while the movie ends with Walter, the protagonist, finding love. Walter also overcomes his low self-esteem towards his boss and says, â€Å"The smartest thing you ever did was hire me!† He goes further in saying that all his boss does is make money of his ideas. The confidence Walter shows at the end of the movie gets him to a higher a position at work. In addition, the movie also leaves you feeling satisfied because the bad guys, the antagonists, are caught and put in prison. Therefore the movie had a more rewarding conclusion than the short story’s inconclusive ending. The movie had much more action, partly because it was more developed, interesting and exciting. The plot involved more than just Walter going to the store to pick up some items for his wife, as in the story. The movie included bad guys chasing Walter throughout the movie because he accidentally took possession of a precious notebook. In addition, it also incorporated Walter committing death-defying feats such as falling out of, and climbing through sky-high building windows, and tiptoeing along the edge of these buildings. Action was also added through the extra daydreams Walter  experienced during the movie, such as the shoot-out near the end of the movie and the Mississippi gambler. Moreover, action was added with Walter running from the bad guys while setting up various booby traps, consequently getting caught in them himself. This caused skepticism in the audience’s faith of Walter’s defeat of the bad guys, but in the end Walter pulled through. As a result of thes e qualities in the movie, action was added, while the short story was dry and exclusive of action. A well-developed plot must have some sort of love interest, action, and a climax, and humor can help. The story did not include these fundamentals. On the other hand, the movie stuck Walter in a very awkward position, which advanced the plot tremendously. Walter’s mother chose Walter’s fiancà ©, whom he did not have feelings for. Then he met Virginia Mayo, the woman of his dreams, with whom he fell in love and ended up marring by the end of the movie. The short story didn’t have a plot; it was just a series of thoughts and daydreams with no climax, conclusion or real development of setting. There was nothing to the book; it just explained a day in the life of Walter Mitty, compared to the movie which involved Walter overcoming chases through windows and through warehouses, his nasty boss, and his over protective, bossy mother. The movie also had a lot of humor in Walter’s clumsy attics, such as when he was running from the bad guy and knocked over the water dispenser, when he broke the window after slamming it behind him, and when he fell through the window in the office during the business meeting. Another example would be when he set up the booby traps for the bad guys and then ended up setting them off himself! With all of these modifications to the short story, the movie’s plot was much more enhanced and developed. The movie, The Secret Life of Walter Mitty, was a more enhanced composition than the story because the movie had a much more fulfilling conclusion, more action and a more complex and advanced plot. The quality of the movie, The Secret Life of Walter Mitty, far exceeded that of the short story upon which it was based.

After commencing their operation in Bangladesh, Banglalink captured a large number of customers. So, other mobile operators’ customers switched the brand. But now from our research we are finding a complete different scenario. In person we are the customers of Banglalink. So, we conducted our research on our friends & the different students’ group of AIUB to get quick access to the information. Our research shows that for the last few years Banglalink’s performance is falling gradually & failing to meet the customer’s requirement. †¢ Most of our respondents have agreed that Banglalink’s call rate is not so high with compare to other operators. But there is also a larger group of respondents who didn’t comply with this statement. †¢ Banglalink’s offered packages are somewhat attractive according to our respondents. A major portion of respondents have agreed that Banglalink is good at promotional activities. †¢ Banglalink’s customer care services are satisfactory in the view of the respondents. †¢ Banglalink has developed its internet facility recently. So, the current customers are satisfied with new services. †¢ In terms of network s ystem there are different opinions among the respondents. In the cities & towns the network is good, but at villages or remote places this service is very bad. As our all respondents are from Dhaka city, the respondents are satisfied with the network service. Banglalink has somewhat contribution in social development regarding our respondent’s view. †¢ There are a few large telecom companies in our country. For the last few years GrameenPhone has been holding the market leader’s place. From our research we can see that Banglalink has no possibilities to become the market leader. Conclusion: In the country Banglalink has come with the mission of â€Å"Din Bodoler Pala†. At their market entrance they showed huge possibilities to become the market leader. They captured the most of their customers within their first two years of operation. But with times customers are leaving Banglalink. Recently a new operator has penetrated into the telecom industry. Besides the former operators are diversifying their packages & offerings. But Banglalink had failed to cope up these new changes in the industry. They also offered some new packages, but those are not sufficient to cope up the situation. To attract different group of customers, Banglalink should take different approaches to gain new customers. Recommendations: Banglalink is a large organization & they are skilled & well experienced to take any decision. Our research shows that dissatisfaction is generating among the customers of Banglalink. So, we have come up with some recommendations: Bibliography To prepare our report we took help from several internet based websites.

Bilingual education benefits everyone Essay Example | Topics and Well Written Essays - 500 words

Bilingual education benefits everyone - Essay Example The political shifts of the 20th century greatly curtailed bilingual efforts and recent political views against it have raised the issue once again. Advocates of an English only system have pointed to the need for national identity, but this approach has led to the sink or swim attitude of educating our students and the effect on the student and society can be detrimental and the cost is certainly high. Students need to progress into our language as well as our society. With a bilingual program, students are taught the desired English, yet have the chance to explore other subjects in their native tongue. This keeps the student on pace and their additional knowledge aids in the learning of English. If a student gets left behind in the sciences, math, or current events due to a lack of English skills, that student will not develop the necessary skills and requirements at an important point in their education. Students who are not struggling with the language barrier are more interested and involved with the material and subsequently perform better. Bilingual education is not a replacement for English, it is a valuable addition to the curriculum. Bilingual education not only provides the only workable approach to teaching non-English speaking students, it also has advantages.

The history of circumcision in the Jewish religion Research Paper

The history of circumcision in the Jewish religion - Research Paper Example The significance of this practice is also subject to various interpretations and theories, largely with religious and social connotations. It is hypothesized that the ancient Egyptians considered circumcision to be a rite of passage from youth to manhood and an initiation into religious rites. Another perspective sees it as a method of purification which may also have aimed to reduce sexual pleasure. There is conjecture that the practice may be linked to phallic worship, being an offering to the deity of fertility or as a substitute for human sacrifice. The fact that the priests of Egypt and the elite of the Aztec and Celebes tribes practiced circumcision, suggests that is may have been a sign of nobility or superior social status. Practical motives, such as cleanliness and freedom from disease are also offered as an explanation for the practice. Some historians argue that it may have been a form of social control exerted by the church. Others see it as a mark of cultural identity, l ike a tattoo, or a sign of slavery. It is even given a psychological significance as a device of ‘pain imprinting’ through which the infant develops a greater threshold of pain and its chances of survival are enhanced. The root of the word is linked to words referring to preparation for the marital state and to purification. Ancient sources link the practice to reasons of hygiene and also as a test of endurance before entry into the adult world. It can only be concluded that circumcision is an initiatory rite with religious significance.

The US Presidential Electoral System Essay Example | Topics and Well Written Essays - 1500 words - 1

The US Presidential Electoral System - Essay Example This research will begin with the statement that the United States Electoral College system is the method that is used to translate the individual votes for a candidate into votes for the office of the presidency. While the system of electoral votes generally reflects the national will, it has the capacity to elect a president with a minority of the popular votes. Since its inception at the birth of our constitutional government, the Electoral College has been an issue that has been widely debated. While some see it as a stabilizing force in our two-party system, others see it as a vehicle that promotes unfair spending and inappropriate voter pandering. Intuition will tell us that in a democracy the popular vote should be the all-important component in the presidential election. Yet, the popular vote can bring the risk of chaos and splintered political parties. The US electoral system is in need of reform, and simple popular vote would be a move towards eliminating the current system 's inadequacies. The Electoral College system of electing a president uses a system where each state has a number of electoral delegates that are equal to the number of the members of the House of Representatives plus two. The voters then vote for a bloc of delegates that represent the individual candidates. After the election, the delegates cast their electoral vote and the winner is decided. This system was necessitated at the birth of the nation when counting a national popular vote was impractical.

Scientific considerations of carbon footprint Essay

Scientific considerations of carbon footprint - Essay Example This is a reason for the alert signal the global warming has created the worldover. The CO2 emission in UK households is shown below, the transport and energy consumption being the biggest emitters (Fig. 1 . from Weidmann and Minx 2007 from SEI et. al. 2006). FIG. 1 1.2 Aims and Objectives of the Report The present report is an attempt to search for the answers of the following: 1. What are the probable effects of climate change on our economy 2. What are the options to the local authorities to reduce carbon footprint of their area.What are their strengths and constraints 3. How do corporate can help combat global warming. Can they be model for cognitive approach to this issue. 4. How sustainable development is linked to environment management 1.3 Effects of Climate Changes on our Economy The climate change due to carbon emission may affect the world economy as follows: - The productivity of food to be reduced, increasing the prices of all basic commodities along with food - Increasing the household and business consumption of energy and costs since coolinguses more energy than heating. - Increasing heat related illnesses and infectious diseases affecting quality of life - Damage to the natural environment and disturbing the biodiversity - Parts of Africa and Asia may become uninhabitable through drought or flooding as aresult other parts of world coming under pressure due to migration (Man.CityCouncil,2008)). 2. Role of Local Bodies in Tackling Climate Change Issue 2.1 OPTIONS AND INITIATIVES Consider an example of Manchester in UK. The Manchester City Council (2008) quotes DEFRA (2004)... Weidmann and Minx (2007) include only CO2 in the analysis though greenhouse gases are a mixture methane, nitrous oxide, sulphur dioxide etc.,along with CO2, many of these cannot be measured like CO2. Moreover, they feel when all gases included it should be termed 'climate footprint' instead since many of the gases do not even have carbon. The emission of greenhouse gases cause global warming i.e. the global temperature may increase more than 2oC by the end of this century. The government has proposed a Climate Change Bill whereby a target of reducing CO2 emissions by 60% by 2050 has been set. But there are doubts about this target as the research indicated that reduction in carbon footprint should exceed 60% to keep temperature increase within 20C. This is a reason for the alert signal the global warming has created the worldover. The CO2 emission in UK households is shown below, the transport and energy consumption being the biggest emitters (Fig. 1 . from Weidmann and Minx 2007 from SEI et. al. 2006). Consider an example of Manchester in UK. The Manchester City Council (2008) quotes DEFRA (2004) that the city emits over 3.3 million tonnes of CO2 annually. The break up is 47% commercial, 30% domestic and 23% transport.

Non-Malignanat Palliative Care -Assignment 2 Assignment

Non-Malignanat Palliative Care - 2 - Assignment Example lignant conditions which need palliative care because of the degree of suffering in the end-stage. One such disease is chronic obstructive pulmonary disease (Croft, 2005). Patients with this condition develop many symptoms which cause great discomfort and despair not only to the patient but also their dear ones. According to Deane (2008), "patients with chronic obstructive pulmonary disease follow a slowly-declining disease trajectory, punctuated by acute episodes of ill health, until the acute episode that proves to be the fatal one." â€Å"More often than not, death is sudden and unexpected† (Deane, 2008). The only solace to such patients would be to provide a comprehensive care which takes care of the physical, psychological, emotional, spiritual and religious needs of the patients so that they lead a peaceful life until their death (Croft, 2005). Such a care is known as palliative care. In this project various aspects of palliative care will be discussed which are individu alized and tailor-made to a 85 year old patient by name James with chronic obstructive pulmonary disease in end-of-life situation. Palliative care needs of patients with COPD James is a known patient of chronic obstructive pulmonary disease and suffers from severe breathlessness, distress, despair and discomfort. Chronic obstructive pulmonary disease or COPD is a devastating medical illness which causes a great degree of human suffering (GOLD, 2008). It characterized by non-reversible airway obstruction due to either emphysema or chronic bronchitis or both. It is not only a major health issue but also a significant source of economic and social burden (Fromer and Cooper, 2008). One of the most frightening and debilitating symptom of COPD is breathlessness which is progressive. The most common cause of COPD is cigarette smoking (Silvermann and Speizer, 1996). This condition affects about 15% of cigarette smokers (NICE, 2004). Many patients with COPD do not receive appropriate end-of0 life care because of the unpredictable course of their disease (Deane, 2008). Along with these symptoms, patients with COPD have other co morbidities which need to be managed too (Deane, 2008). Though the clinical course of COPD is not predicable, end-of-life care is yet possible. In the last year of life, patients like James with COPD are likely to suffer from chronic dyspnea, low mood, weakness, easy fatiguibility and pain (Deane, 2008). COPD most commonly presents as acute infection of the lungs or cough that is productive. The disease is progressive and eventually, the patient develops breathlessness which, over the course of the disease because the most predominant and distressing syndrome. The patient also begins to suffer from exercise intolerance and also easy fatiguibility. All these symptoms make the life of the patient miserable and helpless. The main reason for breathlessness is poor oxygenation of the lungs and ventilation perfusion defects.

The IKEA Business in the UAE According to the Market Demand Research Paper

The IKEA Business in the UAE According to the Market Demand - Research Paper Example In order to acquire the market share and to be labelled as one of the leading businesses in the world, IKEA has its control over the channels of production and distribution (BusinessWeek 2005). Due to the significance of marketing channels for market acceptance and profitability, developing a formal planning process for formulating and choosing channels is vital (Stern & El-Ansary 1982, p. 222). Much of this control is spelt out in its code of conduct that it calls â€Å"The IKEA Way on Purchasing Home Furnishing Products† (IKEA 2010). This code was launched in 2000 (IKEA 2010). It indicates what suppliers should look forward to from IKEA and suggests what IKEA should expect from its suppliers (IKEA 2010). It not only spells out its expectations in terms of legal requirements, working conditions, external environment, and forestry management but also puts a great deal of emphasis on the active prevention of child labour (IKEA 2010). These policies and guidelines will be utiliz ed when implementing the IKEA business in the UAE. As previously mentioned, IKEA’s biggest competitive advantage over other home stores is its low prices. The low prices are the single element that drives IKEA’s cost reduction strategy. This strategy provides the company with its greatest opportunity but also its greatest challenge. The firm is passionate about cutting costs and transferring savings to the customer. This cost-cutting governs the process of design. Therefore, unless a design can be made affordable, it will not end up in IKEA’s showrooms or catalogues no matter how otherwise marketable the item might be.

Teacher Preperation Programs are Failing to Preapare General Education Essay

Teacher Preperation Programs are Failing to Preapare General Education Teachers for Students With Disabilities - Essay Example It is, therefore, very important that all general teachers get general training and additional skills on how to deal and handle cases of disabilities in their classrooms. This is because they are assured that sometimes they will have to encounter such students with disabilities either now or later in their career. Despite this, most colleges do not always provide general teachers with the necessary skills and developments to deal with students with disabilities. Most of the courses offered do not put much effort on the special needs students. Most college courses have insufficient coursework and requirements for proper preparation. Despite the fact that majority of colleges have adopted and developed basic courses on disabilities, there is a general belief that these courses are insufficient to provide knowledge to meet the needs of inclusive students (Kaya & Indiana University, Bloomington, 2008). The classes are just too basic and only introductory that in most cases do very little in providing the necessary knowledge to deal with inclusive students. Most of these coursework are also theoretical and do not provide any relevant life experience where teachers are required to have general knowledge on how to develop a one on one interaction technique with inclusive students. Most of the college curriculums do not also encourage the development and training of teachers. Most of college curriculums were developed before there was a need for inclusive students and therefore in most cases lack the necessary mechanisms of delivering to the students with special needs. It is important that all teachers be well trained on the various ways of communicating with students with different forms of disabilities. For example augmentative and alternative communication systems, communication boards and talking various colleges must install word processors (Sprankle & Wilmington University, 2009). These will

Discrimination Based on Sexual Orientation Presentation Essay Example for Free

Discrimination Based on Sexual Orientation Presentation Essay Discrimination is prejudice toward members of minority or subordinate groups without considering the effects of prejudice and discrimination, discrimination often affects minority groups on the basis of age, race, religion, sex, sexual orientation, etc. If a person or group of people are treated unfairly in areas of public life such as employment, recruitment, customer service and advertising on the basis of their sexual orientation then this is unlawful discrimination. Discriminators don’t always consider the effect of prejudice and discrimination. * Sexual discrimination is also known as ‘homophobia’, this means it  covers a wide range of different viewpoints and attitudes Towards lesbian, gay, bisexual and transgender people. * Homophobia is generally defined as hostility towards and or fears of gay people, however it can also refer to social ideologies which stigmatise homosexuality. This type of Discrimination begins with Negative feelings or attitudes towards non-heterosexual or (non straight) behaviour, identity, relationships and community, this can lead to homophobic behaviour and attitudes. * This is the root of the discrimination experienced by many lesbian, gay, bisexual and transgender or (LGBT) people for short. * Homophobia manifests itself in different forms, for example homophobic jokes, physical and verbal attacks, discrimination in the workplace and negative press coverage. Discrimination against anyone is wrong this chart shows how serious this form of bulling is and how deadly the consequences can be : * Although in many societies gay men and lesbians are more accepted now than they were in the past, homophobia continues to be prominent around the world and in different cultures it is i llegal to be gay, bisexual and transgender. * Heterosexist and homophobia are the result of ignorance about sexual orientation and gender identity issues. Educating society about these issues can help combat fear and discrimination against gay, lesbian, bisexual, and transgender people * Lgbt people are more likely to experience depression and rejection by friends and/or family, acceptance and understanding can even be a matter of life and death, since the risk of suicide in lgbt adolescents is two to three times greater than in their straight counterparts Statistics show thatgt; This shows how discrimination can affect people’s mental health. Direct discrimination Direct discrimination is to directly treat a person or group of people differently because of their sexual orientation and it is against the law in the UK. Direct discrimination occurs when a person treats you less favourably than he or she treats or would treat other persons and it’s based on the grounds of your sexual orientation. * One example of this in employment is where a person is dismissed on the grounds of his or her sexuality. In a non-employment sit uation, this would include situations like refusing to allow a lesbian or gay man to stay in holiday accommodation. Bourn and Whitmore define direct discrimination as: â€Å"Discrimination which entails treatment of a person on one of the aforementioned grounds (for example, gender), which has an adverse impact on him or her by comparison with the treatment afforded to persons not of the group in question†. * Because of the Sexual Orientation Regulations Act 2003, there have been a number of employment tribunal decisions relating to discrimination and harassment of lesbian and gay men. Most people involved used overt homophobic language, and homophobic treatment over a period of time. However there is no requirement for discrimination to be overt or even conscious so even if someone isn’t aware that they are using derogatory terms they are still breaching this act. Indirect Discrimination * Indirect discrimination occurs when an employer or service provider imposes a specific criterion, provision or practices which may apply equally to people of any sexual orientation and does in fact place people of the same sexual orientation as you at a particular disadvantage. * To rely on these regulations you must have personally suffered that disadvantage. As an employer or service provider may be able to argue that the disadvantage was justified, but only if it is a proportionate means of achieving a legitimate end. * One example of potential indirect discrimination would be the provision of benefits referring to marital status since same sex couples can not marry they can however have a civil partnership. It is now no longer lawful to provide such benefits to married persons without providing equal access to such benefits for civil partners. Victimisation can occur if a claim of discrimination has been made. * Victimisation happens when a person treats you less favourably than he or she treats, or would treat, someone else in those particular circumstances because you have done any of the following: * Brought legal actions against the discriminator or any other person under the regulations. * If you have given evidence or information in connection with legal proceedings brought by any person against the discriminator or any other person under the regulations. otherwise done anything under or by reference to the regulations in relation to the discriminator or any other person; or * Alleged that the discriminator or any other person has committed an act which would amount to a violation of the regulations. * Victimisation also occurs where you are treated less favourably because the discriminator knows or suspects that you intend to do any of those things this is known as intimidation. * Allegations of discrimination must be made in good faith so to be protected by the victimisation provisions of the regulations. The extent of individual homosexual discrimination * Individual discrimination is discrimination fuelled by certain attitudes about a minority group, causing the individual to target that group, seeing them as lazy, unproductive, harmful, or unwanted in the society because of their sexuality and background. * Individual homosexual discrimination is discrimination against one person. * For example if a male patient was to refuse medical treatment from a male gay doctor that would be individual homosexual discrimination. One case of individual discrimination I found was: Lesbian police officer wins sex discrimination case against her senior Lesbian police officer court win A lesbian police officer who suffered relentless homophobic abuse at the hands of her sergeant has won her sex discrimination claim. PC Tracey West was regularly taunted by Sergeant Michael Service who claimed gay officers were p**fs and freaks. Sgt Service also made a jibe that her sexuality was an illness and spoke about her civil partnership, asking who would wear the trousers in the relationship. PC West was so traumatised by her six-month ordeal she resigned from Dumfries and Galloway Constabulary then emigrated to Australia. The 42 year-old sued the force and Sgt Service for discrimination on the grounds of sexual orientation. She has now won her case after an employment tribunal ruled she was subjected to a relentless series of homophobic conduct. Sgt Service has been ordered to pay PC West ? 7500 while her former employers must pay ? 2500in compensation. A hearing in Glasgow was told the abuse started in early 2007 at the force headquarters in Dumfries. Sgt Service first made a remark to PC West that he would pass paperwork over the dyke to her at the office they shared. PC West later joined the Gay Police Association. Sgt Service claimed members of the group were all p**fs and freaks. He also told her that a fellow representative from another force could not come into their office. Sgt Service claimed he did not want the p**f in the room and that any money for tea and biscuits was not to come out of his budget. Ms West told the hearing: He apologised for making the p**fs comment and said he didnt know that the term was offensive. He then smirked. He knew what it meant and he was laughing. The sergeant also said that when he spoke about a colleague sounding so gay he meant happy. The mother-of-two made an official complaint in August 2007 after more than six months of constant abuse. Sgt Service was forced to resign in April 2008 after 20 years in the force as a result of the proceedings raised against him. He claimed at the hearing that PC West was lying and that she had made up the accusations to help fund her move to Australia, where her and her partner remain in the police. In a written judgment, employment judge Raymond Williamson said: The claimant was subjected to a relentless series of homophobic conduct by Sergeant Service for more than six months and that she suffered significant distress and hurt feelings. The behaviour contributed to the claimant deciding to emigrate to Australia and remove herself as far away as possible from the unhappy circumstances of life in Dumfriesshire. Institutional discrimination Institutional discrimination is characterized by societal-level conditions that limit the opportunities and access to resources by socially-disadvantaged groups. Institutional discrimination occurs when the culture, policies, systems and procedures in an organisation inherently discriminate against a group or groups of people. This happens because the systems and processes were designed without taking into account the diverse needs of groups within the community in relation to e. g. their sexual orientation. One case of this institutional discrimination I found was: UK Catholic adoption agency loses battle to stop same sex couples adopting. The UK adoption agency Catholic Care has lost its five-year fight to reserve its services for heterosexual couples only, in a landmark court ruling, reports the  Catholic Herald. The adoption agency based in Leeds, had taken its case to the Upper Tribunal in order to win the right to maintain charitable status while being permitted to refuse to place children with same-sex couples, in accordance with the charity’s Catholic ethos. However, they were defeated today as the Charity Commission argued that the charity’s stance is â€Å"divisive, capricious and arbitrary† and undermined the dignity of homosexual couples whose parenting abilities are â€Å"beyond question†. The tribunal concluded that Catholic Care had failed to come up with â€Å"weighty and convincing reasons† as to why the agency should be allowed to discriminate against gay couples who were trying to access their services. Emma Dixon, who was representing the Charity Commission, told tribunal judge, Mr Justic Sales, that Catholic Care’s desired arrangement would iolate Article 14 of the European Convention on Human Rights, which outlaws discrimination on the grounds of sexual orientation and other characteristics. She said: â€Å"A requirement to operate within the tenets of the Church cannot constitute Article 14 justification. â€Å"To do so would be to offer protection to the substance of the Church’ s belief that homosexuality is sinful.

Analysis of of Quercetin in Camellia Sinensis Extracts

Analysis of of Quercetin in Camellia Sinensis Extracts ABSTRACT A precise and feasible reversed-phase high-performance liquid chromatographic (RP-HPLC) method for the novel analysis of of Quercetin in aqueous and alcoholic extracts of Camellia sinensis extracts with internal standard has been developed. The analysis was carried out on a Phenomenax-C18 column (250 Ãâ€" 4.6mm, 5ÃŽ ¼m). reversed-phase column, using a mixture of acetonitrile and 0.1% orthophosphoric acid in water at 60:40 ratio as the mobile phase; Propyl paraben was used as the internal standard. The linearity range of the Quercetin was found to be in 1-25  µg/ml and the retention times were found to be 3.3 and 5.6 min for Quercetin and Propyl paraben respectively. The accuracy was good and recovery values for Quercetin ranged from 100 to 102% respectively. The proposed novel method is precise and feasible for the determination of Quercetin with internal standard in a short analytical runtime. The method seems to be suitable for routine analysis in quality control laboratories an d research institutes. Keywords: Quercetin, HPLC, Propyl paraben, Validation. Introduction Quercetin (Fig. 1) chemically 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one is a plant pigment (flavonoid) found in many plants and foods, such as red wine, onions, green tea, apples, berries,  Ginkgo biloba. It is used for treating conditions of the  heart  and  blood  vessels including â€Å"hardening of the  arteries† (atherosclerosis),  high cholesterol,  heart disease, and circulation problems (1-3). It is also used to treat inflammation,  asthma,  gout,  viral infections,  chronic fatigue  syndrome (CFS), preventing  cancer, and for treating chronic infections of the  prostate (4-7). Quercetin is also used to increase endurance and improve athletic performance. Tooth decay is most common infectious oral disease that afflicts 95% of the human beings. The flavonoids Quercetin found in green tea can stop the formation of dental plaques and tooth decay. Fig.1 : Chemical structure of Quercetin Some analytical methods were developed for analysis of quercetin by spectrophotometric (8-10), HPLC (11-13), HPTLC (14-16), electrochemical detection (17). In spite of its wide economical importance, a rapid and efficient method forits identification and quantification is necessary. To the best of our knowledge, there is no published method for the determination of quercetin in Camellia sinensis extracts with propyl paraben as internal standard. The aim of the present study was to develop a rapid, economical, precise and accurate reversed-phase HPLC method for quantifying quercetin in aqueous and alcoholic extracts of Camellia sinensis. Materials and Methods Acetonitrile (HPLC grade, MERCK), Water (HPLC grade, Thomas Baker) and orthophosphoric acid (HPLC grade), Quercetin and Propyl paraben are procured from local analytical laboratories. Instrumentation and chromatographic conditions HPLC is a chromatographic technique used to separate a mixture of compounds in analytical chemistry and biochemistry with the purpose of identifying, quantifying purifying the individual components of the mixture. The system consisted of UFLC-Shimadzu make LC-20AD with PDA detector. The data acquisitionwas performed by LC solutions software. The chromatographic separation was achieved on Phenomenax-C18 column (250 Ãâ€" 4.6mm, 5ÃŽ ¼m) column. The elution was isocratic with mobile phase of 0.1% orthophosphoric acid in water and acetonitrile (60:40, v/v). The flow rate was 1.0 mL/ min and yielded a backpressure of about 57 bar. The column temperature was maintained at 40 °C, the detection was monitored at a wavelength of 262 nm and injection volume was 10  µL. UFLC is suitable for separation of Quercetin with propyl paraben as internal standard. The chromatographic conditions are shown in Table 1. Table 1: The chromatographic conditions of the developed method Plant material (Camellia sinensis) Dried leaves of Camellia sinensis i.e Green tea are collected from Doddabetta Tea Factory, Ooty, Tamilnadu and identified by Dr. K. Mruthunjaya, Asst. Professor, Department of Pharmacognosy, JSSCP, Mysore. The procured leaves were used for the preparation of alcoholic and aqueous extract. Extraction Methodology: Alcoholic Extract of Camellia sinensis Alcoholic extract was prepared by hot reflux extraction method on a water bath temperature maintained at 78 °C for 2 hours. The dried coarsely powdered leaves of Camellia sinensis (550g) were extracted in 3 batches (150g each). The obtained extract was filtered and solvent was distilled out up to required concentration and combined extract was spray dried to get alcoholic extract of Camellia sinensis and stored in a dessicator. Aqueous Extract of Camellia sinensis Aqueous extract was prepared by hot reflux extraction method on a water bath temperature maintained at 80 °C for 2 hours. The dried coarsely powdered leaves of Camellia sinensis (550g) were extracted in 3 batches (150g each). The obtained extract was filtered and solvent was distilled out up to required concentration and combined extract was spray dried to get aqueous extract of Camellia sinensis and stored in a dessicator. Drying of Extract: Prepared extracts were dried using Spray dryer. Parameters maintained for Spray drying are Inlet temperature maintained at 70-80 °C, Outlet temperature maintained at 50-60 °C, aspiration rate 1200 rpm per min, feed pump 2ml per min respectively. PREPARATION OF SOLUTIONS Preparation of mobile phase The content of the mobile phase was prepared from Acetonitrile, filtered and degassed mixture of and water and orthophosphoric acid in the ratio of 60:40 v/v. Preparation of standard solutions About 10 mg of pure standards of Quercetin and Propyl paraben were accurately weighed and dissolved separately in two 10 mL standard flask and dissolved in methanol to get standard stock solutions of concentration of 1 mg/mL (1000  µg/mL). From the prepared stock solution an intermediate stock solution was prepared which contains 100  µg/mL of Quercetin. From this intermediate stock solution serial dilutions were made to obtain final concentrations of the solutions in the range of 1, 5, 10, 15, 20 and 25  µg/mL of Quercetin. Propyl paraben solution was made to a concentration of 25 µg/mL and used as an internal standard throughout the methodology. Preparation of Camellia sinensis extracts sample solutions 100 mg of extract sample was weighed and transferred in to 10ml volumetric flask and dissolved in a mixture of 5ml of 6M HCl and 5ml of mobile phase and sonicated for 15min. The obtained solution was filtered through a 0.45  µ pore size filter into a HPLC vial and loaded to the instrument. Method development and optimization The chromatographic conditions were optimized by changing the mobile phase compositions; buffer used in the mobile phase column stationaryphase and organic solvent. Finally a mixture of 0.1% orthophosphoric acid in water, acetonitrile and C18 column were used. A typical chromatogram obtained by using the aforementioned mobile phase and column are shown in fig. 2 of blank chromatogram and standard drug quercetin chromatogram is illustrated in Fig. 3. Method validation When a method has been optimized it must be validatedbefore put into practical use. By following the ICH guidelinesfor analytical method validation e Q2 (R1), the system suitability Test was performed and the validation characteristics elinearity, accuracy, precision, specificity, limits of detectionand quantitation were addressed. Preparation of calibration curve Aliquots of quercetin (containing 10- 250  µg/ml) were pipetted into series of 10ml volumetric flask from 100 µg/ml of stock solution followed by addition of propyl paraben containing 250 µg/ml and made up to 10ml with HPLC grade methanol to obtain the final concentrations of 1, 5, 10, 15, 20 and 25  µg/ml of quercetin and 25 µg/ml of propyl paraben solutions were prepared. The responses were measured at 262 nm. The calibration curve was established by plotting the peak areas of Quercetin versus their concentrations. Assay Procedure The column was equilibrated for at least 30 min, with the mobile phase flowing through the system with a flow rate of 1ml/min. Detector was set at a wavelength of 262 nm. Two sets of the sample solutions were prepared containing aqueous and ethanolic extracts with mobile phase mixture. The retention time of Quercetin and Propyl paraben in bulk drug in two replicate samples were found to be 3.3 and 5.6 mins. The peak area of the Quercetin in sample was obtained and the regression equation of the drug concentration over the peak areas was calculated. The RP-HPLC method was used to estimate the amount of Quercetin in aqueous, ethanolic extracts of Camellia sinensis. The typical chromatograms of alcoholic and aqueous extracts are shown in fig. 4 and 5 respectively. It is found that alcoholic and aqueous extract contains 7.35  µg and 4.31  µg per 100 grams of the extract respectively. System suitability The system suitability test ensures the validity of the analyticalprocedure as well as confirms the resolution betweendifferent peaks of interest. A data from six injections ofstandard solutions were utilized for calculating system suitability parameters like %RSD (0.19), tailing factor (1.2), theoretical plates (10728) and resolution (7.8). Linearity and range To assess the linearity, calibration plots of quercetin in each dilution were constructed in the concentration range 1-25 µg/mL the correlation coefficients of quercetin was 0.9998 respectively. Accuracy and precision The accuracy and precision of the developed method was evaluated and results are expressed as percent recoveries 99.3 -101.7%. The precision study of intra-day and interday relative standard deviation was less than 2%, stating that method is more precise. Specificity The specificity test demonstrated that the used excipients did not interfere with the peak of the main compound. The results showed that the developed method was selective for determination Of Quercetin in Camellia sinensis extracts. Sensitivity The limit of detection and limit of quantitation decide aboutthe sensitivity of the method. Tests for the procedure wereperformed on samples containing very low concentrations of analytes based on the visual evaluation method. In thismethod, LOD (signal to noise ratio of 3:1) is determined by theanalysis of samples with known concentration of analyte and by establishing the minimum level at which the analyte can be reliably detected. Accordingly, the LOQ (signal to noise ratioof 10:1) is determined by the analysis of samples with known concentration of analytes and by establishing the minimumlevel at which the analyte can be quantified with acceptableaccuracy and precision (RSD RESULT AND DISCUSSION We developed and validated a simple and efficient reversed phase HPLC method for analysis of Quercetin in Camellia sinensis extracts. Method conditions were optimized by changing the mobile phase compositions; buffer used in the mobile phase, stationary phase and organic solvent. Finally a mixture of 0.1% orthophosphoric acid in water and acetonitrile and C18 column were used. In this study UFLC instrumentation with PDA detection, which is readily available in most analytical and pharmaceutical laboratories, was used. The analytical method was validated as per current International Conference on Harmonization (ICH) guidelines. In addition, in the present study,an internal standard was used to provide higher accuracy and precision of several substances tested, propyl paraben was chosen as the most appropriate internal standard. This substance is stable and does not interfere with the excipients present in of samples and composition of the diluent.Indeed, in the developed method, Propyl paraben was adequately separated from Quercetin. Moreover, its elution time was shorter, which resulted in a short run time of less than 10 min. In the accuracy of the method, recovery is in the range of 98.3-101.7% and standard deviation was less than 2% proves that method is more accurate and precise. The LOD and LOQ values of quercetin are 0.03  µg/ml and 0.05  µg/ml respectively. The described HPLC method was successfully applied for the determination of Quercetin in Camellia sinensis plant extracts.

Convolutional Codes Simulation Using Matlab Computer Science Essay

Convolutional Codes Simulation Using Matlab Computer Science Essay Abstract: In order to reduce the effects of random and burst errors in transmitted signal it is necessary to use error-control coding. We researched some possibilities of such coding using the MATLAB Communications Toolbox. There are two types of codes available Linear Block Codes and Convolutional Codes. In block coding the coding algorithm transforms each piece (block) of information into a code word part of which is a generated structured redundancy. Convolutional code uses an extra parameter (memory). This puts an extra constraint on the code. Convolutional codes operate on serial data, one or a few bits at a time. This paper describes basic aspects of Convolutional codes and illustrates Matlab encoding and decoding implementations. Convolutional codes are often used to improve the performance of radio and satellite links. Key words: Convolutional codes, error-control coding, radio and satellite links. 1. Introduction Convolutional codes are commonly specified by three parameters (n,k,m): n = number of output bits; k = number of input bits; m = number of memory registers. The quantity k/n called the code rate, is a measure of the efficiency of the code. Commonly k and n parameters range from 1 to 8, m from 2 to 10 and the code rate from 1/8 to 7/8 except for deep space applications where code rates as low as 1/100 or even longer have been employed. Often the manufacturers of convolutional code chips specify [1] the code by parameters (n,k,L), The quantity L is called the constraint length of the code and is defined by Constraint Length, L = k (m-1). The constraint length L represents the number of bits in the encoder memory that affect the generation of the n output bits. The constraint length L is also referred to by the capital letter K, which can be confusing with the lower case k, which represents the number of input bits. In some books K is defined as equal to product the of k and m. Often in commercial spec, the codes are specified by (r, K), where r = the code rate k/n and K is the constraint length. The constraint length K however is equal to L 1, as defined in this paper. Even though a convolutional coder accepts a fixed number of message symbols and produces a fixed number of code symbols, its computations depend not only on the current set of input symbols but on some of the previous input symbols. In general, a rate R=k/n, k  £ n, convolutional encoder input (information sequence) is a sequence of binary k-tuples, u = ..,u-1, u0, u1, u2,à ¢Ã¢â€š ¬Ã‚ ¦, where . The output (code sequence) is a sequence of binary n-tuples, v = ..,v-1, v0, v1, v2,à ¢Ã¢â€š ¬Ã‚ ¦, where . The sequences must start at a finite (positive or negative) time and may or may not end. The relation between the information sequences and the code sequences is determined by the equation v = uG , where is the semi-infinite generator matrix, and where the sub-matrices G i , 0 £ i £ m, are binary kXn matrices. The arithmetic in v = uG is carried out over the binary field, F 2 , and the parts left blank in the generator matrix G are assumed to be filled in with zeros. The right hand side of v= uG defines a discrete-time convolution between u and , hence, the name convolutional codes [2]. As in many other situations where convolutions appear it is convenient to express the sequences in some sort of transform. In information theory and coding theory [3], [4] it is common to use the delay operator D, the D-transform. The information and code sequences becomes and They are related through the equation , where is the generator matrix. The set of polynomial matrices is a special case of the rational generator matrices. Hence, instead of having finite impulse response in the encoder, as for the polynomial case, we can allow periodically repeating infinite impulse responses. To make the formal definitions for this case it is easier to start in the D-domain. Let F 2((D)) denote the field of binary Laurent series. The element contains at most finitely many negative powers of D. similarly, let F 2[D] denote the ring of binary polynomials. A polynomial contains no negative powers of D and only finitely many positive. Given a pair of polynomials x(D), y(D)Æ’Å ½ F 2[D], where y(D) ¹0, we can obtain the element x(D)/y(D)Æ’Å ½ F 2((D)) by long division. All non-zero ratios x(D)/y(D) are invertible, so they form the field of binary rational functions, F 2(D), which is a sub-field of F 2((D)). A rate R = k/n (binary) convolutional transducer over the field of rational functions F 2(D) is a linear mapping which can be represented as v(D)=u(D)G(D), where G(D) is a k X n transfer function matrix of rank k with entries in F 2(D) and v(D) is called the code sequence corresponding to the information sequence u(D). A rate R = k/n convolutional code C over F 2 is the image set of a rate R = k/n convolutional transducer. We will only consider realizable (causal) transfer function matrices, which we call generator matrices. A transfer function matrix of a convolutional code is called a generator matrix if it is realizable (causal). It follows from the definitions that a rate R = k/n convolutional code C with the k X n generator matrix G(D) is the row space of G(D) over F((D)). Hence, it is the set of all code sequences generated by the convolutional generator matrix, G(D). A rate R = k/n convolutional encoder of a convolutional code with rate R = k/n generator matrix G(D) over F 2(D) is a realization by linear sequential circuits of G(D). 2. Convolutional encoder simulation The Convolutional Encoder block encodes a sequence of binary input vectors to produce a sequence of binary output vectors. This block can process multiple symbols at a time. If the encoder takes k input bit streams (that is, can receive 2k possible input symbols), then this blocks input vector length is L*k for some positive integer L. Similarly, if the encoder produces n output bit streams (that is, can produce 2n possible output symbols), then this blocks output vector length is L*n. The input can be a sample-based vector with L  =  1, or a frame-based column vector with any positive integer for L. For a variable in the MATLAB workspace [5], [6] that contains the trellis structure, we put its name as the Trellis structure parameter. This way is preferable because it causes Simulink [5] to spend less time updating the diagram at the beginning of each simulation, compared to the usage in the next bulleted item. For specify the encoder using its constraint length, generator polyno mials, and possibly feedback connection polynomials, we used a poly2trellis command within the Trellis structure field. For example, for an encoder with a constraint length of 7, code generator polynomials of 171 and 133 (in octal numbers), and a feedback connection of 171 (in octal), we have used the Trellis structure parameter to poly2trellis(7,[171 133],171). The encoder registers begin in the all-zeros state. We configured the encoder so that it resets its registers to the all-zeros state during the course of the simulation: The value None indicates that the encoder never resets; The value On each frame indicates that the encoder resets at the beginning of each frame, before processing the next frame of input data; The value On nonzero Rst input causes the block to have a second input port, labeled Rst. The signal at the Rst port is a scalar signal. When it is nonzero, the encoder resets before processing the data at the first input port. 3. Convolutional decoder simulation 3.1. Viterbi Decoder The Viterbi Decoder block [7], [1] decodes input symbols to produce binary output symbols. This block can process several symbols at a time for faster performance. If the convolutional code uses an alphabet of 2n possible symbols, then this blocks input vector length is L*n for some positive integer L. Similarly, if the decoded data uses an alphabet of 2k possible output symbols, then this blocks output vector length is L*k. The integer L is the number of frames that the block processes in each step. The input can be either a sample-based vector with L  =  1, or a frame-based column vector with any positive integer for L. The entries of the input vector are either bipolar, binary, or integer data, depending on the Decision type parameter: Unquantized Real numbers; Hard Decision 0, 1; Soft Decision Integers between 0 and 2k-1, where k is the Number of soft decision bits parameter, with 0 for most confident decision for logical zero and 2k-1, most confident decision for logical one. Other values represent less confident decisions. If the input signal is frame-based, then the block has three possible methods for transitioning between successive frames. The Operation mode parameter controls which method the block uses: In Continuous mode, the block saves its internal state metric at the end of each frame, for use with the next frame. Each traceback path is treated independently. In Truncated mode, the block treats each frame independently. The traceback path starts at the state with the best metric and always ends in the all-zeros state. This mode is appropriate when the corresponding Convolutional Encoder block has its Reset parameter set to On each frame. In Terminated mode, the block treats each frame independently, and the traceback path always starts and ends in the all-zeros state. This mode is appropriate when the uncoded message signal (that is, the input to the corresponding Convolutional Encoder block) has enough zeros at the end of each frame to fill all memory registers of the encoder. If the encoder has k input streams and constraint length vector constr (using the polynomial description), then enough means k*max(constr-1). In the special case when the frame-based input signal contains only one symbol, the Continuous mode is most appropriate. The Traceback depth parameter, D, influences the decoding delay. The decoding delay is the number of zero symbols that precede the first decoded symbol in the output. If the input signal is sample-based, then the decoding delay consists of D zero symbols. If the input signal is frame-based and the Operation mode parameter is set to Continuous, then the decoding delay consists of D zero symbols. If the Operation mode parameter is set to Truncated or Terminated, then there is no output delay and the Traceback depth parameter must be less than or equal to the number of symbols in each frame. If the code rate is 1/2, then a typical Traceback depth value is about five times the constraint length of the code. The reset port is usable only when the Operation mode parameter is set to Continuous. Checking the Reset input check box causes the block to have an additional input port, labeled Rst. When the Rst input is nonzero, the decoder returns to its initial state by configuring its internal memory as follows: Sets the all-zeros state metric to zero; Sets all other state metrics to the maximum value; Sets the traceback memory to zero; Using a reset port on this block is analogous to setting the Reset parameter in the Convolutional Encoder block to On nonzero Rst input. 3.2. APP Decoder The APP Decoder block [8] performs a posteriori probability (APP) decoding of a convolutional code. The input L(u) represents the sequence of log-likelihoods of encoder input bits, while the input L(c) represents the sequence of log-likelihoods of code bits. The outputs L(u) and L(c) are updated versions of these sequences, based on information about the encoder. If the convolutional code uses an alphabet of 2n possible symbols, then this blocks L(c) vectors have length Q*n for some positive integer Q. Similarly, if the decoded data uses an alphabet of 2k possible output symbols, then this blocks L(u) vectors have length Q*k. The integer Q is the number of frames that the block processes in each step. The inputs can be either: Sample-based vectors having the same dimension and orientation, with Q  =  1; Frame-based column vectors with any positive integer for Q. To define the convolutional encoder that produced the coded input, we have used the Trellis structure MATLAB parameter. We tested two ways: The name as the Trellis structure parameter, for a variable in the MATLAB workspace that contains the trellis structure. This way is preferable because it causes Simulink to spend less time updating the diagram at the beginning of each simulation, compared to the usage in the next bulleted item; For specify the encoder using its constraint length, generator polynomials, and possibly feedback connection polynomials, we used a poly2trellis command within the Trellis structure field. For example, for an encoder with a constraint length of 7, code generator polynomials of 171 and 133 (in octal numbers), and a feedback connection of 171 (in octal), we used the Trellis structure parameter to poly2trellis(7,[171 133],171. To indicate how the encoder treats the trellis at the beginning and end of each frame, its necessary to set the Termination method parameter to either Truncated or Terminated. The Truncated option indicates that the encoder resets to the all-zeros state at the beginning of each frame, while the Terminated option indicates that the encoder forces the trellis to end each frame in the all-zeros state. We can control part of the decoding algorithm using the Algorithm parameter. The True APP option implements a posteriori probability. To gain speed, both the Max* and Max options approximate expressions by other quantities. The Max option uses max{ai} as the approximation, while the Max* option uses max{ai} plus a correction term. The Max* option enables the Scaling bits parameter in the mask. This parameter is the number of bits by which the block scales the data it processes internally. We have used this parameter to avoid losing precision during the computations. It is especially appropriate for implementation uses fixed-point components. 4. Conclusions In these work we have constructed and tested in Maple convolutional encoders and decoders of various types, rates, and memories. Convolutional codes are fundamentally different from other classes of codes, in that a continuous sequence of message bits is mapped into a continuous sequence of encoder output bits. It is well-known in the literature and practice that these codes achieve a larger coding gain than that with block coding with the same complexity. The encoder operating at a rate 1/n bits/symbol, may be viewed as a finite-state machine that consists of an M-stage shift register with prescribed connections to n modulo-2 adders, and a multiplexer that serializes the outputs of the adders.

T.S. Eliots use of Poetic techniques in The Lovesong of J. Alfred Prufr

T.S Eliot, widely considered to be one of the fathers of modern poetry, has written many great poems. Among the most well known of these are â€Å"The Waste Land, and â€Å"The Love Song of J. Alfred Prufrock†, which share similar messages, but are also quite different. In both poems, Eliot uses various poetic techniques to convey themes of repression, alienation, and a general breakdown in western society. Some of the best techniques to examine are ones such as theme, structure, imagery and language, which all figure prominently in his poetry. These techniques in particular are used by Eliot to both enhance and support the purpose of his poems. The theme of Prufrock is the negative, individuality repressing effect that society has on its people. The Prufrock persona illustrates this, he is alienated by the inane social rituals that define his life, â€Å"I have measured out my life with coffee spoons† and make it insignificant and useless. The Waste Land’s theme is that the world, in particular western civilisation, is a culturally and spiritually barren place. Society is portrayed as a pile of â€Å"†¦stony rubbish†¦Ã¢â‚¬ , the ruins of a once great city now reduced to rubble where nothing can grow. Lives mean nothing, but the poem also offers hope through a return to basic religious values, ending with the repeated chant of â€Å"Shantih shantih shantih†, which means, â€Å"the peace which passeth understanding†. The poems both portray the same basic idea, but they have two main differences. Firstly, there is the way in which the themes are expressed. In Prufrock , Eliot uses a pers ona as an example of the debilitating effect of living with so many expectations, rules, standards and meaningless rituals has on a the individual. In many ways, this is a very effe... .... Figuring very prominently is Dante, with the epigraph in Prufrock an exact quote from Inferno, and more subtle references found in The Waste Land that are very suggestive of a Dantean descent into hell. Dante, and to a lesser extent Joseph Conrad, from whom Eliot derives a certain amount of horror, which subtly complements his themes, have had a profound impact on Eliot’s writing. He chooses to quote or allude to parts of other works that complement his own. The techniques used by Eliot in creating both The Waste Land and Prufrock, are used in largely similar ways as far as furthering his purpose, yet differ slightly in style or small alterations when examined more closely. Some techniques, such as imagery, are more similar than others. Though he may use devices differently for each poem, it is only in such a way that makes them unique, and conveys his purpose.

Trojan War Essay -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In the book The Trojan War, by Bernard Evslin, Ulysses and Agamemnon both contribute to the Greek’s victory. Many considered Ulysses to be the real brains behind the Greek forces. Although Agamemnon was the leader of the Greeks, many would say he was not a good one. Even though Agamemnon did some good deeds during the war, many of his actions caused problems, and Ulysses often had to come to his rescue.   Ã‚  Ã‚  Ã‚  Ã‚  With Ulysses on the Greeks side they had amazing intelligence and bravery. Many great things happened because of Ulysses leadership. One example is when Ulysses dressed as a peddler, found where Achilles was hiding, and brought him back to fight in the war. Ulysses knew he had to find Achilles because the prophecies told the Greeks they couldn’t win the war without him. Secondly, Ulysses convinced the Greek forces to return and fight after Agamemnon almost lost them. He yelled to the troops â€Å"Stop! Agamemnon means battle and not retreat, you misunderstood his words† (p. 42). Lastly, Ulysses showed great smartness when he solved the riddle about the Trojan War. By him solving the riddle, the Greeks came to win the long war. Ulysses was also smart enough to think of hollowing out the horse so the Greeks could hide inside them and attack the Trojans while they were sleeping. He showed intelligence too when he pretended the horse was a sacrifice to the god Poseidon. The war may not have turned out the same if the Greeks ...

Building successful parent-teacher partnerships Essay

The problems in the school life can be solved if teachers and parents work together as a team. â€Å"The traditional concept of involving parents in the process of educating their children has typically been restricted to one-way communication approaches. Either the parent is talking at the teacher or the teacher is talking to the parent. Yet the real purpose of parental involvement in the educational process is to foster an improved learning climate and support system for the child. Parent-teacher confrontation models do little to foster the development of their environments conducive to effective interaction and learning for the child† (Swick, 7). â€Å"parents and teachers must come to realize that their behaviors are much more important than their words in affecting the child’s self-concept. When parents and teachers work in complementary, supportive type roles as partners in the development of learning climates and support systems for young children, not only are they learning, but they are a vital part of the educational process† (Swick, 7). â€Å"†¦ the parent is the first and most important influence in the child’s development. It holds that the parent, like all other teachers,must first be a growing, compassionate person in order to be an effective parent† (Swick, 7). â€Å"Parents and teachers become stronger, more insightful individuals when they participate in joint determination of the educational program in which their children have optimal conditions necessary for growth toward becoming functional and developing persons† (Swick, 8). Parents provide personal information about children’s behaviors, characteristics, talents, interests, etc. Teachers give another view about the social development of the children for example with friends and other people, progresses in school, skills, achievements, etc. Involved parents: The hidden resource in their children’s education by Anita Gurian, Ph.D. Gurian, Anita. â€Å"Involved Parents: The Hidden Resource in Their Children’s Education† NYU Child Study Center. Available: 01 May 2012. Web Page. â€Å"In adolescence, children become more independent and usually don’t want their parents in school. In middle and high school, students have to deal with more courses and more teachers in a more impersonal way, so parent involvement, although less direct, is still critical. Parents can participate in events at school, monitor homework, provide experiences and materials that supplement course work, and help children with organizational strategies. Parents can influence their children’s academic progress by encouragement, reinforcement, and modeling. Children learn from their parents’ own learning styles and activities, such as discussions, newspapers and other reading materials, television habits and quests for information and knowledge.† When parents want to be in charge and spent their time for their children, they can have the opportunity to know their child’s life better.

Napoleon was a child of the Enlightenment Essay

Assess the validity of this statement by using specific policies and attitudes of Napoleon. During the time period of the French Revolution, many governments came and went as a result of the unorganized and often times, radical political regimes that were recklessly installed by desperate people longing for equality and liberty. The French were inspired by the new liberal notions and ideas of political and economic rights for all proposed by Enlightenment thinkers. As different forms of governments and their leaders among them passed, one man named Napoleon Bonaparte rose to power by manipulating the Directory and the French people to enable him to assume authoritative powers over his subjects and, as a side effect, majority of continental Europe. Bonaparte used his autocratic powers to maintain the rights achieved during the revolution and inject new Enlightenment he had been educated from the small island of Corsica as long as they did not interfere with his thirst for power. Napol eon Bonaparte rose to power via the arrogance of a political leader who failed to comprehend the influence of Bonaparte and his army. Napoleon Bonaparte issued a constitution, the Constitution of Year VIII, to clarify his new political intentions he would impose. With this constitution, he created an illusion to the French people that people from all fractions of the political spectrum would be content with. His constitution appealed to the common man and democratic supporters with â€Å"universal male suffrage.† An elaborate system of checks and balances between each sector of his government appealed to republican supporters. Also, the Council of State would satisfy any monarchists that remained in France. However, as an intellectually-inclined individual from his education in philosophy and military strategy, Bonaparte provided the French with a sound and stable state and what appeared to be a constitutional government in which he knew that the public would eat up his legal proposition. Bonaparte also simplified and cleaned up the French government and its legal system with reforms such as the Civil Code o f 1804, or more commonly known as the Napoleonic Code. Napoleon Bonaparte created reforms that were based off of the education he received as a boy from the Age of Enlightenment that would thus act as a tool for nation-building and continental domination. Napoleon Bonaparte demonstrated from his enlightened point of view that religion could be separate from government–but does not have to be totally eradicated from society itself to achieve such an intention–with the concordat with Pope Pius VII. He also treated all faiths equally by emphasizing that the state was supreme over whatever religion or denomination it may be like how he enacted laws on both Protestant and Jewish communities in the Roman Catholic dominated France. Bonaparte maintained the abolishment of the practice of primogeniture. Napoleon also went on a rampage all of Europe to expand his empire. As he marched throughout Europe, he liberated peasants by eliminating the economic and social practice of serfdom. Napoleon Bonaparte developed in an environment that was saturated with philosophical ideas pertaining to social and religious ideas that Enlightenment thinkers studied and discovered new ways of the ways people could interact such as religious toleration and social equality. Napoleon Bonaparte grew up in a home that was greatly influenced by Enlightenment ideas and principles. This statement can be reached with Bonaparte’s actions that were obviously liberal and new to the decades prior to the French Revolution. He did assume total control over France and the continent of Europe, but he did permit some liberty and freedom to his loyal subjects. Bonaparte used Enlightenment ideals to gain power and used them to maintain power by convincing he was still providing what the liberal bourgeois and nobility had been fighting for and along with some new ideas that did not go against his drive for authoritative powers. In all Napoleon Bonaparte utilized his Enlightenment education to manipulate the French and free many serfs and to control France and later Europe.

Police Department Roles and Functions Essay

There are many various functions of police agencies. Patron, traffic, juvenile services, intelligence and undercover, and special operations are just some of the various functions of police agencies. There are many differences between the functions of the police agencies and the federal, state, and the local levels. There are reasons of why you need to have various functions and roles of policing in any community. There are a few various functions of police agencies such as patrol, traffic, juvenile services, intelligence and undercover, and special functions. There are many functions of the patrol and consists of protecting the lives of people and their property, repression of criminal and delinquent behavior, identification, apprehension and conviction of offenders, traffic flow, collision reduction, maintenance of order and public safety. Patrol functions are a major part of policing agencies. Traffic functions consist of identifying potential traffic problems and hazards, arresti ng offenders, investigation property damage and personal injury automobile accidents, regulating parking on the streets and municipal buildings (Grant & Terry, 2008). Traffic functions keep the roads safer and make things flow better for traffic. Juvenile services are there to help juvenile offenders go to counseling and counseling for the juvenile’s families. There are also programs that can help juveniles learn about drugs, alcohol, abuse and gangs. There is a program called (D.A.R.E) Drug Abuse Resistance Education. (GREAT) Gang Resistance Education and Training is another program that is used to inform the youth group about the negative impact of gangs. Intelligence and undercover is where officers go and use a different identification so that they can get closer to suspects or fugitive or get evidence (Grant & Terry, 2008). They may have to live in different places and dress as complete different people then who they are so that they can  fit in to the environment they are trying to get close to. The last function is the special operations that consist of S.W.A.T and the canine unit. The S.W.A.T stands for special weapons and tactics and they functions are dealing with high risk law enforcement such as hostage situations and arresting people that are armed and dangerous suspects. The canine unit is having a police dog that helps on searches. Searches could be consisting of drug investigations, tracking and searching for victims or suspects, vehicle searches, and searching of buildings (Grant & Terry, 2008). The police agency functions differ from the federal, state, and local level. The federal has two main functions that split into a few different functions. The Homeland Security and Department of Justice have many functions. The Homeland Security has the Bureau of Customs and Border protection (CBP) and this helps make sure that people and cargo are crossed borders legally and safely. Bureau of Immigration and Custom Enforcement known as (ICE) works with the smuggling of drugs and weapons. It also helps remove illegal immigrants that should not be across the borders. ICE also helps protect and secure federal buildings. FEMA is the Federal Emergency Management Agency and their goal is to help prevent man-made disasters from destroying cities. FEMA also helps after man-made disasters happen with providing food, water, and shelter to the people that have homes that are destroyed or have no stores that have food remaining for them to eat or drink. Department of Justice has a few functions as well that are to help protect on a higher level than the police agencies. Drug Enforcement Administrators (DEA) deal with enforcing laws that pertain to controlled substances. The Federal Bureau of Investigations (FBI) has many functions. They protect against any kind of terrorist attack against the country, foreign intelligence operations, cyber based attacks, public corruption, and white collar crimes. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) deal with the investigations of the trafficking of illegal firearms. The ATF also enforces federal laws that pertain to federal taxes on alcohol and tobacco (Walker & Katz, 2011). The federal and the police agencies have many differences. The federal have more of a variety of different functions than the police agencies. The state does not have as many functions as the federal but still have functions that make a difference. The State has some functions that the police agencies also have. The State has different kind of  officers. There are State police and Highway patrol officers that patrol the highways statewide. They also have power to give traffic violations, criminal investigations, and arrest non traffic violators (Walker & Katz, 2011). The police agencies also do a lot of patrol just like the state police. The local levels are a lot like the police agencies. They have municipal officers, county police and they h ave sheriffs that patrol city roads. They attend to more serious crimes that are committed in the city. The local level deals with order maintenance problems and emergency services (Walker & Katz, 2011). The county police have the same functions as the municipal officers but can operate countywide. The sheriffs have more functions than the municipal officers and the county police. The sheriffs have to go to courts and deal with corrections. When it comes to the community all of the policing agencies are very important. There are many functions and roles that help keep a safe community. If there are limited policing agencies in the community it could raise the rate of crime, accidents, and deaths. With having the functions in the communities it helps make the people of the community feel safer knowing that the policing agencies are out patrolling the streets whether it is by foot, bike, car, or horse. Without having the functions of trafficking there would be more accidents on the roads or highways. If the juvenile services the younger generations may not have the resources to learn about awareness programs for drugs, alcohol, and abuse. They may not have the opportunity to change their lives by attending counseling to help better themselves. Without having undercover officers it would be a little harder to catch suspects before they actually commit a crime. Even though not all cities have the canine unit, the canine unit helps search for things that the human nose cannot detect as well as a dog can. The canine unit is a very big help for searches when victims are missing or are searching for drugs. There are many functions and roles for all police agencies no matter how big or how small the agency is. There are many differences between the police agencies and the federal, state, and local level. But there are also some functions that are the same. Without having functions of all the police agencies there would be more crime and accidents within the cities and states. Having as many functions in all the policing agencies makes this place a safer place for everyone. References Walker, S., & Katz, C.M. (2011). The police in America: An introduction (7th ed).
