Music Vs Modern Music A Lesson From The Past Generation

October 3, 2017 1975s music VS Modern music A lesson from the past generation. †¢ Recent days, I have heard some interesting arguments about Vietnamese music in the past and music that popular these days. Originating from the comments of people from the past generations and the new generation on Face book. In their opinions, some of them consider that popular music these days have lowered the value of the melody and did not appreciate the aesthetic taste of music anymore. Some other, mostly the youth consider the opposite. They think that the new era music is more fitting for the taste of people these days. †¢ I have to admit that, from 2000 to 2008, when I often listen to the old songs, which back in my time people called†¦show more content†¦I realized one thing; I miss it, Vietnamese music from 1975s, and the songs from the era that was called the most glorious periods of the music of Vietnam. For me to understand more about this issue. Today I have a meeting with Mrs. Ha Tran, who is aware and spend a lot of time to analyze the differences between Vietnamese music during the 1975s and now. ________________________________________ †¢ â€Å"Young musicians these days play so many roles. Most of them are from professional musicians, and then went on to become singers, then later producers, sometimes music critics. Also, they follow the trend that influenced the Western music, or pop dance music. It can be said that the compositions of young musicians and singers are commendable in the age of the music trends, that prevalent in the world. However, there are two most important things that young musicians are missing from the older generation of musicians. They are composer s creative environment and the uniqueness of the music† Mrs. Tran said. †¢ First, the young composer s creative environment is not an environment that allows true liberal arts to be created, because they are bound by cultural censorship by the government. Most of their songs are composed only based on limited topics. For example, love, friendship, education, or to express the nationalism inside them. Unlike the US or other Western countries, all swear words are forbidden.

Defects of Education in India Free Essays

EDUCATION in its broadest, general sense is the means through which the aims and habits of a group of people lives on from one generation to the next. Education as a science cannot be separated from the educational traditions that existed before. Adults trained the young of their society in the knowledge and skills they would need to master and eventually pass on. We will write a custom essay sample on Defects of Education in India or any similar topic only for you Order Now In pre-literate societies this was achieved orally and through imitation and story-telling etc . Oral language developed into written symbols and letters. Schooling in this sense was already in place in Egypt between 3000 and 500BC The gurukula system was the ancient system of education. A gurukula is a type of school in India, residential in nature, with shishyas living in proximity to the guru, often within the same house. In a gurukul, shishyas reside together as equals, irrespective of their social standing, learn from the guru and help the guru in his day-to-day life. They did not accept fees ONLY ASMALL GURUDAKSHINA WHICH MAY NOT BE MONETARY. INDIA S ANCIENT GURUKUL SYSTEM IS WORTH EMULATING BY ALL INTERESTED IN IMPARTING EDUCATION. THE GURUKUL SYSTEMBRINGS A SENSE OF RESPECT AND COMMITMENT FROM THE TEACHERS AND THE STUDENTS Nalanda and Takshishila universities were the oldest university-system of education in the world. Indian education suffered a huge blow as Western education became ingrained into Indian society with the establishment of the British empire. the British so cleverly played their cards that even after fifty years of independence we still continue to exist in a state of stupor, unable unwilling to extricate ourselves from one of the greatest hypnoses woven over a whole nation. Indian curriculum is criticized for being based on rote learning. Our present day education system gives no chance to creativity. It is marks , grades and competition all the way . It should inculcate good values in the minds of students. Emphasis should also be given on physical and vocational training. Teaching of ethics should be incorporated in the curriculum right from kindergarden through high school. Children should be allowed to choose their own subjects acc. to their interests. They must be made to interact with each other in groups and express their views on various topics. Instead of taking notes from voluminous books , teachers etc they must be made to get information by themselves and share it with the class. This will help them to develop good analytical skills and reading habits . Children must have practical experience . They can be taken on trips to museums, labs, etc where they can learn by interacting with experienced people. Education is to gain and share knowledge. Sharing without communication is impossible. English should not be banned at the primary level as it remains the global language. Learning hindi, the national language and the state language helps in internal communication. The system of Education in India should focus on learning and not exams. Unfortunately Education has become a lucrative business destroying the real purpose of itself. The bad quality of education in govt schools have given a thrust to the the rise of commercial coaching classes all over India. Students today hardly think of being a teacher due to less perk†¦ many who are hardly passionate about engineering and medicine are studying just for the sake of getting a fat salary and package along with it. Middle class parents pay what is demanded by the coaching classes, this has alarmingly turned out to b an industry in our nation. Statistically 25% of the Indian population is illiterate, only 7% of the population that goes to school manage to graduate and 15% manage to make it to high school. 80% of schools are managed by the Govt. , private schools are expensive and out of reach for the poor Another reason for poor quality of education is the poor quality of teachers in government schools . Government schools are unable to attract good quality teachers due to inadequate teaching facilities and low salaries. To improve the quality of education , the government needs to spend more money from its coffers on education. The really critical aspect of Indian public education system is its low quality. The actual quantity of schooling that children experience and the quality of teaching they receive are extremely insufficient in government schools. A common feature in all government schools is the poor quality of education, with weak infrastructure and inadequate pedagogic attention. Conclusion School teachers SHOULD BE PAID high SALARIES and, every care is to be taken that these teachers keep on upgrading. The government should realize that these are the people who shape their future generations. All over India the syllabus must be same, because partiality occurs between students. . Frankly it would be foolhardy to believe that a syllabus consisting a bit of maths bit of science, arts and literature is a foolproof way to educate whole of India. Our present day system of education can be revamped and changes incorporated by getting a group of experienced teachers from various parts of our country. The task is best done by them and not by a bunch of politicians who do not have any training in education. Hope to see the Indian system of education reach its zenith like it did in ancient times!

Taxis and Accessible Services Division †Free Samples to Students

Question: Discuss about the Taxis and Accessible Services Division. Answer: Introduction: In 2008, Garret Camp sold StumbleUpon to eBay while hanging out with a fellow entrepreneur called Travis Kalanick. The camp was interested in solving Taxi problem in San Francisco. The original idea was to first obtain drivers, a parking spot in a garage, and a Mercedes S class. The cost would be split among the entrepreneurs alongside an iPhone application. By March 2009, the two businessmen came up with a name which was UberCab. In June 2009, Camp hired Kalanick as the Ubers chief incubator as the former ran a full-time gig at Stumble Upon. Seven months later, Oscar Salazar, Camp and Kalanick changed the name of the company to Uber tested the prototype of the service on the streets of New York. With the help of investors, Uber raised $11in February 2011. Over the next six months, Uber spread its wings to Boston, Washington D.C, Seattle, and Chicago and later on went global. By 2016, Uber was offering its services to over 540 cities (Chokkattu, 2016). Probably the most recognized startup companies, that demonstrated the potency of the internet and possesses a really inorganic progress is Uber. It is an app which recognized as a business that has the biggest number of automobiles yet, it never possesses a single vehicle on its own. Uber is a ride application which takes the place of people needing to leave their residences to hail a taxi. Currently, the taxi arrives to your doorstep. Uber features an amazing and low costs plan for its customers making it a popular application for the regular and even random travelers. A lot of office going masses are now frequently choosing an Uber cab rather than driving to work on their own. Strengths Uber is an accepted Brand Worldwide with reputation in more than 50 nations. Uber has now overtaken Automobile titans such as General Motors. Together with growing internet penetration, Uber is anticipated to expand quickly in the forthcoming years (Hartmans McAlone, 2016). Uber, as an aggregator, will not need higher fixed investment and thus it can be much easier for Uber to incorporate much more cities to their network (Alley, 2016). Uber has constantly prioritized client satisfaction. Uber has recognized it is serving within a completely client motivated industry where there is competition. To maintain an advantage over the opponents, it requires to offer far better client satisfaction and improved user experience. Uber has implemented the vibrant pricing technique that operates within the demand and supply theories of economics (SFMTA, 2016). High demand, High price. This gets to be advantageous for the business as well as the operators. In the busier hours, operators make a lot of money. Uber can also be seen to adjust perfectly to business situations. Due to its worldwide exposure, Uber faces numerous issues in several regions. Uber is an intelligent marketer and has adjusted well anywhere it has set up its enterprise. It possesses a high level associated with service, approved operators and vehicles. Uber Black customers take pleasure in extremely high levels of service. Possesses an unlimited number of vehicles. Typical Taxi service rules are not pertinent for Uber. Almost no competition. A significant rival is Lyft. Dual ranking system increases trust and security. Weaknesses Operators are definitely the image of the organization and therefore the organizations impression is dependent upon the conduct of operators towards the client. This can be a highly unrestrainable circumstance even though stringent rules are given to the operators. Uber is intensely reliant on online connectivity to increase and develop within developed nations. Therefore, it is confronting difficulties within developing as well as emerging nations where internet is poor and very slow. Digital Literacy within the developing countries is low and therefore technology dependent applications like Uber just serve individuals who are technologically up-to-date. Controversies: Uber has experienced controversies previously for the reason their drivers' behavior. This impacts the impression of the organization and trust falls within the clients minds. Uber is at a market in which the barriers to entrance are incredibly low therefore it will encounter competition in several fronts. The partnership involving Uber along with the drivers is ethically dubious. Therefore, expected trustworthiness between Uber and its operators is fairly low. Furthermore, the business and its clients do not have bonding. Motivation to stay with Uber is definitely low. There exist privacy issues. Uber keeps records of where clients board the taxis from. Additionally, it documents where he or she goes. Opportunities Clients are unhappy using the unorganized Taxi market. This provides a chance for Uber to fully make use of. This is certainly the primary reason behind UBER's success. Local cab operators are regarded as rude and don't conform. Growing online penetration: In India, the government is working to digitize the country. The number of smartphones tend to be growing and technology dependent programs like Uber may increase their products and services to some other cities and expand their presence within the country. Increasing income: Along with increasing disposable income, clients are prepared to spend more on convenience. Alternative transport: Uber chopper was launched in several nations and may try to find additional transport method catering for local requirements. A bus aggregator can be introduced in India. Poor transport by the government: In countries such as China and also India with huge populations, individuals are fed up with making use of general public transport, Uber offers a type of personal privacy and relief in which the customers get their own space. Logistics: Uber may introduce movers assistance where individuals may look up for movers within the nearby region through Uber. Clients are usually disappointed with conventional cab businesses due to higher rates and long holding out time. It may take advantage of new and large markets in nations such as India whereby the taxi industry is troublesome and costly. Tapping developing markets within suburban locations where taxi services are certainly unavailable. Uber may raise the valuation. This could attract considerably more investors. Consequently, Uber may have additional money to work with. Less expensive electric automobiles may be used. It is going to reduce the price and boost the operators profit margin. Special transport: Extra services such as hauling elderly patients to medical centers, transporting kids to school and also transporting domestic pets to the veterinarian could be provided. Threats Unclear government regulations: The main point of difference involving cab aggregators and also government bodies concern their legal standing and if they ought to be handled as traditional taxi firms or as IT firms. Retention of customers as well as switching of brands: As levels of competition increase, it gets harder to retain clients and also operators of Uber. Any kind of economic benefit may swing the customers along with operators from Uber. Low profit margins for drivers: Uber assists the drivers to acquire a large number of daily trips but it rarely has a huge-profit margin to offer its drivers and therefore they can effortlessly be poached. This also puts off other drivers who would like to join UBER (Hall Krueger, 2015). The unorganized industry of cab operators may revolt against companies like UBER that happen to be depriving them of their source of income. Such revolt will jeopardize UBER's operations (Cramer Krueger, 2016). A number of new laws in nations such as Germany may suspend UBER from carrying out its activities. Issues with local government councils can result in penalties. It will likewise lead to a negative PR. Rising levels of competition will inevitably lower prices. This can dissuade drivers from becoming members of UBER in new marketplaces. This may bring about lack of clients. Ubers profits will fall. Self-driving automobiles, for example Google Cars, may eradicate the requirement for Uber (Basker, Foster Klimek, 2015). Over-valuation can bring about Over-investment in places that have no space for an identical venture. Target marketing Uber guarantees long lasting customer connections and roll-outs new techniques to take care of the ones that are still to be attained. Ubers style of selection demonstrates how the business adopted ensuring numerous products for each segment. Positioning could be described by 4Ps of marketing. Product: transport service industry Price: Surge pricing; whenever more customers are available, the prices increase as compared to when customers are few; Surge pricing. Place: This could be comprehended through the geographic segmentation perspective. Uber has a tendency of focusing more in to the cities because of its increased population and also increased possibility of drivers and luxury transportation needs from passengers. Promotion: Uber advances its recognition through word-of-mouth, Hilton, Microsoft Outlook, connecting with services such as google, along with other market sectors such as eating places. The marketing strategy implemented by Uber is the single segment. It is inclined to make sure all feasible demographics within the segment are searched into in depth and client responses and simplicity becoming their greatest concern. With all the increasing reputation, the idea of Uber continues to be replicated by diverse establishments through the globe. The most popular Uber business structure is currently known as Uberification. Lyft along with Ola are a handful of primary rivals of Uber. Ola which is Indian based, posed a threat to Ubers share in the market however, the quality expertise that Uber offers, individuals developed comfortable spot for the company. Products within Uber's marketing mix Uber offers individuals with the choice to ride on cabs reserved using mobile phone apps or personal computer web site (Berger Frey, 2016). Uber has turned the transport service to be much more accessible and comfy. Wi-Fi facilitated cabs as well as car-pooling take client experience to another level (Akerman, Gaarder Mogstad, 2015). A number of the different services offered by Uber that individuals are making use of on every day basis around the world include: Uber-Moto: The service enables individuals to reserve bike rides and wander across the city at a very cheap price. Uber Go: It is probably among the most popular Uber service. You may reserve your personal car as well as move from place to place and being able to access Wi-Fi. Uber Pool: This is actually the car-pooling service that allows you to journey along with other travelers moving in exactly the same direction like yours (Kopp, Gerike, Axhausen, 2015). This can be less expensive and helps to decrease the number of vehicles on the road. Uber X: That's where Uber win the hearts of many. You can reserve expensive vehicles using Uber X get treated to the very best of comfort as well as style. Places in Ubers marketing mix Uber started out in United States but conquered other parts of the world (Berger Frey, 2015). In India, Uber has changed how individuals travel to their places of work and back. It is cost-effective, comfy and more secure than any other modes of transport. Uber operates in Three Tiers within every nation, where cities are classified cities according to infrastructure, population and development (Lin, 2011). Uber extended to Paris. Its there that an international experience was put to test which provided them with the self-assurance to develop internationally. With the global operations, Uber grew to become one of the most valuable start-up on the globe. Individuals from all over the world wanted a change and Uber has offered that. Uber obviously utilizes Penetration pricing. It has eliminated the exploitation of travelers. Consumers now access Uber and travel peacefully. Since one vehicle can be utilized by 10-11 individuals daily, population levels decrease due to decrease in vehicles on the road (Uber, 2017). Pricing remains to perform an important role in the interest in Uber globally; the organization provides probably the most comfortable trips at the lowest price. Individuals are pretty pleased with the prices and are utilizing the choices that are available such as Uber Go, Uber pool and the Uber-Moto (Greiner, 2016). In order to get to know the system of potential growth in the United States, more so the transport industry, it requires the utilization of Porter's five forces. It is a developing transport company that has a huge presence in NY. Within years after its inception, the company gained trust from customers which has guaranteed expansion and opportunity to offer better services (Casadesus-Masanell Didiomov, 2015). It encounters very stiff competition from other firms such as Lyft Risk of New Entrants Uber is not protected from firms that are entering the market that could unreasonably bill a lesser rate a similar mileage. During its inception, the co-founders injected substantial amounts of investment. Uber's plan is to provide their software at no cost to ready clients (Beaudry, Doms Lewis, 2010). The services may be changed at absolutely no charge. Since the need to balanced out cost gets to be forthcoming. This can be very since it decides the business's success within the industry. Uber does not own any vehicle within its fleets. As a result, the firms business structure is extremely reliant on operators and associates possessing their very own cars. Uber makes use of an outsourcing method for its labour and also resources to individuals that fulfil the requisites to use their first web application. It is additionally difficult to substitute certain operators. Vehicle owners tend to be allowed the liberty to select from the company or competitors therefore can make a deal for a considerably better focus on the expenditure of the firm. Therefore, it is actually irrefutable that the vendors possess an advantage in affecting Ubers overall performance. In comparison with various other porters forces, bargaining power of supplier is reasonable in Ubers situation. Clients do not always need Uber services regularly. In fact, only particular instances such as lateness which make the clients to request Uber services. Clients can easily choose from Lyft, Uber, or perhaps other rising organizations. The transfer charge is also reduced for clients since Ubers free of charge application just needs client sign up. Ubers clients are very sensitive to changes in rates granted the existence of alternatives and rivals (Casadesus-Masanell Didiomov, 2015). Because of such elements, the buyers huge power may restrict the earnings for the firm, therefore strengthening it as a powerful force. An alternative is a very common force within a competing business condition. As a result, existence of variety can be sufficient to limit the firm from increasing their prices. It is important to note that a minor raise of Uber prices may result in client adoption of its nearest competitors as well as replacements. Besides, general public methods of transportation that provide identical services at the cheapest price may jeopardize Uber's presence. A continuing risk of substitutes is now a fragile force with regards to Uber. Lyft is a primary rival to Uber. The business possesses a virtually similar business structure as well as functions (Fedorchenko, 2017). The two firms do not just compete for a bigger market share but also for clients. A contemporary enterprise environment calls for companies to focus on a client base in a particular physical region to reduce the operations expense. This is actually the scenario regarding Lyft as well as Uber. It features an established system as well as huge capital investment (Casadesus-Masanell Didiomov, 2015). Essentially, this is the market leader, although minor differentiation approaches restrict the firms possibilities. Due to the domination of Uber, competition is not a strong force. Uber is definitely a force to reckon within the transportation industry. Nevertheless, it needs to improve on its creativity approaches so that it can benefit. Transportation business within the United States features a lot of substitutes as well as competing organizations. Lowering of operational costs is essential to refrain from increasing client charges in order to survive. Conclusion Uber business model has been a benchmark to many businesses. There are other organizations that are offering identical services as those of Uber. It encounters several difficulties that include legal and regulations in the United States and beyond. Regardless of the difficulties, Uber has continued to gain popularity among users. Its loyal clients assert that Uber is currently bring a transformation in the transport industry. Investors on the other are confident that Uber will cement its place in the market in future. Uber needs to implement protocols that ensure that their drivers as well as riders are safe, independent contractors utilizing their application program adhere to the required laws. The bright future belongs to Uber only if it sorts out this existing concern in order to strengthen their clients trust and attain long-term achievement.

Slang In America Essays - Sociolinguistics, Slang,

Slang In America For hundreds of years, English has been continuously changing. Words that were unacceptable 300 years ago are now commonplace. English has always had a trademark of being a comfortable language, the language of the common people (MacNeil 143). Change in the grammar and diction of a language is natural, and English is always confronted with changes. Among them are the use of slang, clipped word endings, and new dialects. Some Conservatives do not like changes because they claim that standard English is a perfect language; they do not want to corrupt it. Others simply do not like change. Neither group of Conservatives has any new arguments, and nothing to fear from change. Slang worries Conservatives the most because it affects the vocabulary of English. American English, especially, is always adding new words to its vocabulary for social, scientific, or artistic reasons. The scientific and artistic words do not bother these people; only the social, or slang, words do. Slang is usually created by children or teens who seek social status (Morrow 137). Because kids are the source of new slang, some adults look down on it with the assumption that kids are unintelligent and simply rebelling against established English grammar and diction. However, most of the adults did the same thing when they were children. Adults have been frowning on slang for generations (Crystal 104). Conservatives also look down upon slang because slang is not used by people of high status. If they hear someone speaking in Jive, they will be angry because Jive is not the way that high class people speak. People who do not like slang are usually prejudiced as well. They do not want to hear other ways of talking because it deviates from the way they talk. Also, much slang comes from other languages, of which Conservatives might also be prejudiced. The dialect that a person uses may make him comfortable, but this is not considered. If a language is not comfortable, why would you want to speak it? Language has always changed to fit the paradigms of society (Crystal 105). For example, in Shakespeare's time, many contractions used today were considered poor English. Rarely could a person of high social status be found using "don't" in a sentence. Today, however, people may use contractions without fear of being scorned by society. This simply illustrates The same types of people who opposed contractions in the past are opposing slang and new dialects of English. They do not realize that the way they speak differs from the way that their predecessors spoke. People opposed to language change only defend their dialect, which will die out anyway, and prove their intolerance of change. Language will be thought of differently in the future because new mediums of communication will be used, the largest one being the Internet. Today, many people are using the Internet to "talk" to people all over the world. The Internet has its own language, which Conservatives view as computer slang. No matter what diction or dialect you speak, you still have to type out an Internet message in standard Internet. There are words used specifically for the Internet, usually acronyms that are universally understood, that will probably appear in dictionaries in the future. Conservatives have no reason to bother with whether a person's dialect or diction will be understood in spoken language, because most communication will be typed, not spoken, in a neutral Internet language. Conservatives claim that the lack of standard English is due to an education deficiency. They explain that the reason some slang is created by kids in inner-city areas is that the kids drop out of school, because the kids are stupid, and therefore never learn standard English. In reality, the kids drop out of school because they are told that the way they speak is stupid (Seymour 123). The Conservatives are not willing to help the kids with "bad" dialects. Perhaps this is because of a prejudice, sort of "once slang, always slang" mentality. The Conservatives should use the kids' dialects to help the kids learn standard English. Conservatives have one reason to oppose language progression: fear. Conservatives have a fear that the language they speak will not be the primary one. For this reason, they will put down other dialects simply because these dialects are not standard English. Standard English is just another dialect, however, and thinking one dialect greater than another is mere bigotry. If Conservatives had their way, people would never be able to express themselves in new ways because there would never be

Stalin essays

Stalin essays Stalin did not demonstrate truly wise and honourable leadership of his country, and it was only because of the unstable nature of Europe at this time that the people of Russia trusted and put their faith in him. Stalin was the son of an alcoholic cobbler and a washerwoman, and was all too aware of the privileges of class. He came to loathe anyone wealthier than himself (he even annihilated the Kulaks, a wealthy peasant class) and was obsessed with a vision of liberating his native Georgia from the rule of the Tsars. Trotsky wrote that Stalins hatred of the oppressors was much stronger than his love of the oppressed, and even Lenin did not want Stalin to succeed him. Stalins has often been compared with Hitler, but while Hitler only left graves, devastation and degradation in Germany, Stalin turned a starving, destitute land into a powerful industrial state. However, this gain, and Russias increase in territory in Eastern Europe, came at enormous cost to the Russian people. To understand why Stalin led Russia in the way that he did after the war it is first necessary to go back and see how he operated during World War Two. When the Second World War broke out, Stalin decided to claim neutrality. His idea was that if all the countries of the world went to war with Germany by the end of the war they would all be financially and politically exhausted. Russia, having been at peace, could then rise to be the greatest power in the world and eliminate capitalism. When Stalin decided that it was actually in Russias interest to enter the war he intended to side with a nation(s) that opposed Nazi expansion, but due to his distrust of the west, he ended up as an ally of Germany. He considered Germany to be the lesser of two evils, and Nazi Germany offered him something he could not refuse when it took control of areas of Soviet interest and was willing to give the Baltic States and part of Poland to R...

Tips for Teachers on Creating a Dyslexia-Friendly Classroom

Tips for Teachers on Creating a Dyslexia-Friendly Classroom A dyslexia  friendly classroom begins with a dyslexia friendly teacher. The first step toward making your classroom a welcoming learning environment for students with dyslexia is to learn about it. Understand how dyslexia impacts a childs ability to learn and what the main symptoms are. Unfortunately, dyslexia is still misunderstood. Many people believe that dyslexia is when children ​reverse letters and while this can be a sign of dyslexia in young children, there is much more to this language-based learning disabilities. The more you know about dyslexia, the better you can help your students. As a teacher, you may worry about neglecting the rest of your class as you institute changes for one or two students with dyslexia. It is estimated that 10 percent to 15 percent of students have dyslexia. That means you probably have at least one student with dyslexia and possibly there are additional students that have never been diagnosed. The strategies you implement in your classroom for students with dyslexia will benefit all of your students. When you makes changes to help students with dyslexia, you are making positive changes for the entire class. Changes You Can Make in the Physical Environment Have an area of the room designated as a quiet area. Carpeting this area will help keep down noise. Minimize distractions to allow students with dyslexia to have an area they can read or concentrate on class work. For students with dyslexia who are showing signs of anxiety, this can be a time-out area when they are feeling very nervous, upset or frustrated.Place analog and digital clocks on the wall, right next to each other. This will help students see both ways of showing time, connecting the digital time with how it looks on a clock.Set aside several areas of the board for daily information. Write down the day and date each morning and post the days homework assignments each morning. Use the same spot each day and make your writing large enough for them to easily see it from their seats. Large writing helps students with dyslexia find their place when copying information into their notebooks.Post high-frequency words and information that is used often around the room. For younger children, this could be the alphabet, for elementary age children it could be the days of the week, for older children it could be word walls of vocabulary words. Strips with this information can be taped to the students desk as well. This helps to reduce memory work and lets children with dyslexia focus on other skills. For younger children, add pictures to the words to help them connect the written word with the object. Have children with dyslexia sit near the teacher. This doesnt necessarily mean they must sit in the first seat but they should be able to easily see the teacher using peripheral vision. Students should also be seated away from talkative children to minimize distractions. Teaching Methods Use slower speech and simple sentences. Students with dyslexia may need a longer time to process information, use pauses when speaking to give them time. Integrate examples and visual representations in lessons to help aid in comprehension.Provide worksheets for organizing information for writing assignments. Have templates with different types of writing frames and mind maps that students can choose from when preparing a writing assignment.Do not require a student with dyslexia to read aloud in class. If the student volunteers, let him read. You might want to offer a student the opportunity to read aloud and give her a few paragraphs to read and practice at home before speaking out loud.Integrate different ways for students to show their knowledge of a subject. Use visual presentations, powerpoint projects, poster boards and discussions to help a child participate without feeling embarrassed or fearing failure.Use multi-sensory lessons. Students with dyslexia have been found to lear n better when more than one sense is activated. Use art projects, skits, and hands-on activities to reinforce lessons. Assessments and Grading Allow students with dyslexia to use electronic helpers when completing class work or tests. Examples include an electronic dictionary, speller or thesaurus, computers and talking calculators.Do not take off points for spelling. If you mark spelling errors, do so separately and create a list of words frequently misspelled for students to refer to during writing assignments.Offer oral testing and extended time for formal assessments. Working Individually with Students In the beginning of the school year, work closely with a student to assess their knowledge of phonics and set up a plan and specific practice sessions to help strengthen weak areas.Assess a students strengths and weaknesses. Use teaching methods to help build on strengths. Children with dyslexia may have strong reasoning and problem-solving skills. Use these as building blocks.Praise a childs achievements, no matter how small.Use positive reinforcement programs, instituting rewards and consequences to help a child learn to cope with symptoms of dyslexia.Supply a schedule of the school day. For younger children include pictures.Above all, remember that students with dyslexia are not stupid or lazy.

Was The Black Panther Party a successful force for change during the Essay

Was The Black Panther Party a successful force for change during the civil rights years - Essay Example its aims and policies (Wikipedia.org), rejecting armed resistance and instead focusing on tackling matters relating to social, economic and political inequality not only of African Americans, but also other minority groups in the country. The BPP efforts, however, were not only unappreciated, but also vehemently opposed by the government, Federal Bureau of Investigation {FBI} and the police, resulting in its unfortunate and untimely demise after a promising span of just 14 years. While it lasted, the BPP undoubtedly represented a successful force for change during the civil rights years. The general situation refers to the circumstances prevailing in the country since the Civil War ended. The War, hailed as the destroyer of slavery of blacks after having suffered years of oppression, did not in fact result in the anticipated assimilation of blacks into American mainstream society. Oppression of blacks continued in the form of Ku Klux Klan atrocities, widespread lynching of blacks and the de facto refusal to grant them all civil rights. Blacks responded by non-violent means, forming representative organizations to put forward their protests. The National Association for the Advancement of Colored People {NAACP} was created to foster assimilation of blacks into mainstream American society. The Universal Negro Improvement Association {UNIA} headed by Marcus Garvey was established to foster independence of blacks. Not only did these associations prove ineffective, the response of white Americans – violent, suppressive and unbending – showed no signs of com promise. Blacks continued to live in oppression in the United States (Blackpanther.org). The specific situation followed the groundbreaking Civil Rights Act that the United States Congress enacted in 1964. It prohibited racial discrimination in public facilities. The Act was the culmination of the Civil Rights Movement spearheaded by Dr. Martin Luther King Jr. – a struggle that involved nonviolent blacks being

Plato vs Aristole Political Philosophy Essay Example | Topics and Well Written Essays - 1500 words

Plato vs Aristole Political Philosophy - Essay Example Philosophers were prominent people to those societies since they were influential to the people. Plato and his student Aristotle are well known for their efforts and contribution to the society on matters concerning governance and leadership. This paper will therefore, analyze the views of Aristotle and Plato towards governance. The essay will focus on their views towards self-interest and property. Philosophers around the world consider Plato as the greatest philosopher of western civilization. Although western civilization was characterized by a by democracy and capitalism, Plato considered communism government and lifestyle as the most appropriate. According to Plato, democracy and capitalism were just experimental ideologies that were not practical (Benardete 134). Plato considered communism as the most applicable lifestyle in people’s lives. According to his utopian society, the success of a government can only be defined by the success of its people. Plato also considers that a society is best governed by its best minds. A society can only be ruled by its best mind when there is limited competition or self-interest within the society. In such society, people would be working towards the realization of a common goal. This is the basis of communism according to Plato. The best minds of a society are the kings or philosophers within that society. Plato considers a socialist society as a society that is governed by wisdom and proved knowledge. A society that is different from Plato’s society is governed on un-established knowledge. The philosopher considers a socialist society to be better than a capitalist society. A communist society as described by Plato is a selfless society such society people work towards the realization of common goals. According to Plato, a utopian society can only be realized if people adapt knowledge. Plato acknowledges that people in an ideal society have no desire for power and common interests and goals drive them. People need knowledge to tame their desire for power and self-interest. According to Plato, people with self-interests are uneducated and therefore, quality education will eliminate people desire for power. Educating people will make them change their attitude towards the community and the country and, this will eliminate their desire for power. Application of knowledge is power; an educated person will be able to visualize the relationship between power and knowledge. According to Plato, relevant education will make the people understand the relationship between power and knowledge. This will make people compete for power based on their knowledge. People with less knowledge therefore consider themselves less appropriate to take leadership positions The love for the public is the second strategy that Plato proposes to use in order to tame people’s desire for power. Plato proposes that creating the love towards the nation among people makes them have an obligation towards the nation. This is followed by a separation of self-interests from national issues. People who have love for the nation assume responsibility over the nation and, this eliminates their desires for power. People who are hungry for power cannot establish an ideal nation that Plato proposes. People can only live satisfactory lives if they establish a gap between their self-interests and national interests (Allen 76). Plato is confident that acquisition of knowledge can tame desires for power and sel

Business Etiquette Essay -- GCSE Business Marketing Coursework

Business Etiquette The Importance of Etiquette Etiquette has always been an important part of life, be it social or business. However, it seems that business etiquette is has become more important in the last decade. This is mainly due to the fact that the business world is becoming more global and that â€Å"relationship selling† has become must for success. Etiquette is important for a variety of reasons. It helps to ease what might become and uneasy situation and can make or break business relationships that are worth millions of dollars. In essence, etiquette helps people to understand what is appropriate in any situation. It is also important to know the difference between business protocol and business etiquette. Business protocol determines what actions you take in a situation. Etiquette tells you how to take those actions. According to Ann Marie Sabath, there are a few guidelines that professionals should follow. Firstly, be proactive. Find ways to establish relationships with clients before they need to purchase something from you. Secondly, send a thank-you note. If someone is willing to give you 15 minutes of their time than they deserve a written thank-you. And thirdly, be a good sport. Even if you have been turned down by a client, thank them for giving consideration to your company (Bass, 2000). The Effects of Social Etiquette on the Business World The business world of the past encompasses a predominantly male environment with innate, discerned guidelines. Today, the business arena has changed with the civil rights movement and the entry of women into the workplace. The changes continue to evolve with other sociocultural issues. In order to be successful in the business world a masterization of business etiquette is imperative. There is a sizeable difference between social etiquette and business etiquette. Social etiquette is primarily based on chivalry, which includes the concept of protecting women. Business etiquette, on the other hand, includes military origins based on hierarchy of power. This effects the behavior in the business world in as much as men and women are treated equally as peers. For example, if one should hold the door open for a woman, he/she should open a door for a man in the same situation. Regardless of gender doors are held open for superiors, clients, peers following close on one heel... ... integral part of our daily lives. It is very easy to slip into â€Å"casual speak† when dealing with business e-mails. However, business professionals should keep in mind that they are dealing with other businesses and the same formality use when face-to-face should be used for writing and sending business e-mails. It may also be a good idea to take a few tips from the pros†¦literally. There are several services that provided by etiquette consultants. Many of these services can be found online or in your nearest bookstore. Knowledge it the most important aspect of good business etiquette. Works Cited 1. Alihan, M. (1970). Corporate Etiquette.

Calcium Absorption Essay

In order to determine the content of calcium and magnesium in an unknown sample of limestone, the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry, emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured?. The calcium concentration or ppm can be measured using the absorbance of the solution and comparing it to a standard curve for calcium?. Whereas magnesium, needs to be determined using the standard addition method. The concentrations of each respective molecule can be presented as CaO and MgO percentages of the unknown limestone sample. Materials and Methods The compound calcium carbonate (CaCO3, CAS: 471-34-1, 204. 89ppm) was utilized to compare its absorbance to the unknown sample of limestone # 8066 on the standard curve. Moreover, magnesium sulfate heptahydrate (MgSO4*7H2O, CAS: 10034-99-8, 40. 8ppm) was also utilized to compare its absorbance against that of the unknown. Lab personnel from the CSU Eastbay department of chemistry stockroom performed all calibrations on the Perkin Elmer AAnalyst 300 atomic absorption spectrometer. All chemicals used in this experiment were obtained from the CSU Eastbay department of chemistry stockroom. A Denver Instrument Co. Sargent-Welch analytical balance was used to determine the mass of the unknown, mass of calcium carbonate, and mass of magnesium sulfate heptahydrate. A Perkin Elmer AAnalyst 300 atomic absorption spectrometer equipped with a Lumina Calcium and Magnesium Lamp was used to determine the absorbance. The instrument used Argon and Acetylene as the carrier gas and oxidant gas, respectively.

Light-Induced Transformation of Amyloplasts Into Chloroplasts

Plant Physiol. (1984) 75, 142-145 0032-0889/84/75/0 142/04/$01. 00/0 Light-Induced Transformation of Amyloplasts into Chloroplasts in Potato Tubers' Received for publication November 9, 1983 and in revised form January 19, 1984 YU S. ZHU, DENISE L. MERKLE-LEHMAN, SHAIN D. KUNG* Department of Biological Sciences, University of Maryland Baltimore County, Catonsville, Maryland 21228 ABSTRACT The transformation of amyloplast into chloroplasts in potato (Solawum tuberosum L. ) tuber tissue can be induced by light.Excised potato tuber discs illuminated with white light of 3000 lux bepgn to synthesize chlorophyll after a lag period of 1 day, and continued to synthesize chlorophyll for 3 weeks. In this paper we present evidence, based on ultracentrifugal sedimentation and immunoprecipitation, that the lightmediated synthesis of Ribulose-1,5-bisphosphate carboxylase began 1 day after illumination with white light. When illuminated the chloroplasts isolated from light-grown potato tuber tissue incorporated I3SImethionine into polypeptides, one of which has been idenified as the large subunit of Ribulose-1,5-bisphosphate carboxylase.These chloroplasts are functional as determined by 02 evolution in the Hill reaction. A great deal of data is now available on the biochemistry of the development of chloroplasts from etioplasts (6). Much less is known about the development of chloroplasts from amyloplasts, a starch storing organeile, which exists in storage tissue, roots, and some callus. It is well known that potatoes turn green on exposure to light for several days.Not only does the study of the organelle transformation and light-regulated gene expression stimulate theoretical interest, but the greening of potato also has some practical importance, since the greening of the potato is accompanied by the formation of the poisonous alkaloid, solanine (5). The morphological and ultrastructural changes in the development of chloroplasts from amyloplasts were described in several electron microscopic studies (3, 11). In this communication we present some biochemical evidence to show the function of chloroplasts from potato tuber based on the biosynthesis of Chl, RuBPCase,2 and Hill activity. lates in sterile Petri dishes (9 cm), 40 discs per dish. The discs were illuminated at room temperature by fluorescent tubes with intensity of 3000 lux. Chlorophyll and RuBPCase Determination. Chl was determined according to Arnon (2). RuBPCase was detected with a Model E analytical ultracentrifuge, as previously described (9). Schlieren pictures were taken at 44,770 rpm, 10 min after attaining this speed. An Ouchterlony double diffusion test was employed to determine the RuBPCase specifically. The antiserum was prepared against RuBPCase from tobacco (15).Light-Driven Protein Synthesis in Choroplasts. Ten g of green potato tuber discs which had been exposed to white light for 7 d were homogenized in a Waring Blendor with cold isolation buffer (sucrose 0. 35 M, Hepes-NaC l 25 mm, EDTA 2 mM, isoascorbateNa 2 mm, pH 7. 6) and filtered through 2 layers of Miracloth. The resultant filtrate was centrifuged at 30g for 1 min to remove starch granules, and the supernatant was then centrifuged at 2500g for 1 min. The pellet was resuspended in 1 ml of KCI suspension (KCI 0. 2 M, Tricine-KOH 66 mm, MgCl2 6. 6 mM).The chloroplast suspension was transferred to a Petri dish (3 cm in diameter) and incubated with [135S]methionine (10 ,uCi) at room temperature under white light (4000 lux). During a 2 h incubation, the incorporation of [35S]methionine into proteins was measured. After the 2 h incubation the radioactive polypeptides were separated on an SDS-polyacrylamide gradient gel (815%), followed by fluorography as described by Blair and Ellis (4). 02 Evolution Assay. The ability of chloroplasts from potato tuber discs to evolve 02 was measured in the Hill reaction ccording to the procedure of Marsho et al. (12). The incubation system consisted of ferricyanide 1. 7 mm, methylamine 3 mm, glyceraldehyde 10 mm, and chloroplasts corresponding to 15 yg of Chl in a total volume of 0. 6 ml. The reaction was initiated by irradiation with red light (22. 4 mw/cm2). The 02 evolution was measured and recorded with a polarograph.

After centrifugation at 12,000g for 10 min, 20 Ml of the supernatant were used for assay of RuBP Case. hundredth of the Chl content in normal leaves. This is primarily due to fewer chloroplasts per cell. The chloroplasts were not distributed uniformly in discs and were probably linked to some specific ultrastructure in the cortex. Microscopic observation revealed that the amyloplasts were comprised of two types: large (55 x 80 Mm) and small (5-20 Mum). Most of them were stainable with I2-KI. Upon exposure of the discs to light the small amyloplasts only turned greenish.RuBPCase Biosynthesis in Potato Tuber during Greening. Since RuBPCase is the most abundant soluble protein in the chloroplasts (10), it can be used as an important biochemical marker of chloroplasts. The de novo synthesis of RuBPCase was clearly demonstrated by ultracentrifugal sedimentation (data not shown) and specific immunoprecipitation (Fig. 2). The Schlieren pattern of extracts from normal leaves consists of four peaks representing 80S cytoplasmic ribosomes, 70S chloroplast ribosomes, 18S Fraction I protein (RuBPCase), and 4 to 6S Fraction II proteins (8, 9).The extract from potato tuber stored in the dark lacked the peak of RuBPCase, whereas a small peak was observed in discs exposed to 3 d of light, indicating the light one initiated the synthesis of RuBPCase (data not shown). The biosynthesis of RuBPCase was also demonstrated by an Ouchterlony double diffusion assay (Fig. 2). The light-mediated synthesis of RuBPCase started at 1 d after illumination and increased during greening. The RuBPCase content was estimated to be -6 ,ug/g fresh potato tuber tissue, whereas the RuBPCase content of a typical green leaf is 5 to 10 mg/g fresh tissue (10).Further evidence for the de novo synthesis of RuBPCase in light-treated potato tuber was obtained from the experiment on light-driven protein synthesis in chloroplasts. The chloroplasts, isolated from potato tuber discs after illumination for 7 d, exhibited a higher activity of protein synthesis, as demonstrated by the incorporation of [35S]meth ionine into proteins (Fig. 3). In contrast to light-driven protein synthesis in chloroplasts, the chloroplasts in the dark and especially amyloplasts, either in the light or dark, exhibited a very low protein synthesis activity.A number of radioactive polypeptides synthesized in the chloroplasts in the light were recognized on SDS-polyacrylamide gels followed by fluorography (Fig. 4). It was observed that some chloroplast polypeptides (mol wt 39,000, 50,000, 52,000, 55,000, 94,000, 96,000) were synthesized more readily in the light than in the dark. One of these polypeptides co-migrated with purified unlabeled LS of RuBPCase (mol wt 52,000), and was identified as the LS, based on this and results presented in Figure 2.There is also one strongly light-initiated polypeptide (mol wt 64,000) which does not appear in the dark. 02 Evolution of Chloroplasts from Light-Induced Potato Tubers. Upon illumination with red light, the chloroplasts, isolated from light-treated potato tuber discs a fter 3 weeks of light treat- 144 Plant Physiol. Vol. 75, 1984 ZHU ET AL. sure to light, the amyloplasts are transformed into chloroplasts, which have a different function. The changes in ultrastructure of potato tuber amyloplasts during greening were investigated by electron microscope.It was shown that the main developmental features were elongation of vesicles into thylakoids, the differentiation of grana and the appearance of ribosomes in the stroma (3), although the ultrastructure is generally less well developed compared to that for normal leaves. On the other hand, there is very little information on biochemical alterations in potato tuber during greening. To confirm the transformation of amyloplasts into chloroplasts, this study provides some biochemical evidence: (a) the synthesis of photosynthetic pigments, (b) the synthesis of RuBPCase and other proteins, and (c) Hill reaction activity.Before illumination the potato tubers contain no Chl or Pchl, but do contain carotenoid which increases during greening (1). Very low light intensity (400 lux) was required to initiate greening. The light may penetrate into the potato tuber discs and evoke the development of chloroplasts from amyloplasts. During the development of chloroplasts from amyloplasts, assembly of Chl into the newly synthesized membranes occurs. Cold storage may cause the breakage of membranes (13); however, some studies suggested that amyloplast membranes remain intact in cold storage (14).It was frequently observed that the chloroplasts were formed as streaks in the potato tuber discs, suggesting a special structure is linked to the chloroplast development. The Schlieren pattern of the extracts from light-induced potato tuber tissue as well as its immunoprecipitation reaction with antiserum to RuBPCase demonstrated that RuBPCase, an important enzyme in the photosynthetic carbon cycle, was de novo synthesized during greening. This result was further confirmed by the active light-dependent pro tein synthesis in the isolated chloroplasts.The biosynthesis of RuBPCase during greening suggests the involvement and operation of CO2 assimilation in the chloroplasts. Furthermore, the photosynthetic function of electron transport and 02 evolution in isolated chloroplasts from potato tuber was shown by the high Hill reaction activity. The transformation of amyloplasts into chloroplasts is absolutely light-dependent. The fact that red light did not stimulate this transformation indicates that phytochrome may not participate in this regulation. This coincides with the result that potato tuber does not have phytochrome (7).What is the photoreceptor in this light-induced organelle transformation? How does light turn on the genes for the development of chloroplasts, and turn off the genes for the development of amyloplasts? Undoubtedly, this system provides an attractive and challenging model for investigations into the molecular mechanisms underlying the photoregulation of development and gene expression. FIG. 4.

Arrows indicate the mol wt of light-stimulated polypeptides and band corresponding to LS. Although the dark-incubated sample was more concentrated than the light-incubated sample (R), the fluorograph (L) indicates there was more incorporation of [35S]methionine into the light-induced polypeptides than into the dark-initiated polypeptides, demonstrating that more polypeptides were synthesized in the light than in the dark.

Satanism Essays - Church Of Satan, Left-Hand Path, Satanism

Satanism Essays - Church Of Satan, Left-Hand Path, Satanism Satanism Sociology/Psychology I am hoping I can somehow make this seem like a psychological report without making it lose any of it's important details. My goal in writing this paper is to hopefully make people understand and agree that Satanism is not a "Devil Worshipping," animal mutilating, child scarifying cult organization. The psychological thing comes in when people say Satanism is wrong or evil, they hear the word Satan and automatically assume that it must be bad. They make these assumptions without even taking the time to find the facts and understand them. I'll start off by saying that Satanists do not worship the devil! A Satanist believe that he or she as an individual rule their own destiny and are the god of their own lives. Satanism is a religion based on the reality that man is an animal, like all others. They choose to separate themselves from a society where natural behavior is suppressed and the strong support the weak. The average Satanist disagrees with much of Christianity. In many ways Chr istians are considered the enimies. Christians say Satan is a fallen angel, not a God. All religions have gods and demons, some of which are forbidden by a typical society. Satan is one among these, originally conceived by the Hebrews, long before the birth of Jesus. Most Satanists are familiar with the teachings of Christianity, and have read the Bible or part of it. They simply consider the Bible to be false and disregard it much like Christians would disregard books which represent the foundation of another religion. Satanism is not considered a religion for the white race and should not be confused with or grouped together with skinheads, The KKK, Nazi's, Neo-Nazi's, or people who support white power. Satanists are not teenage vandals, not gang murderers, not psychopathic murders, not child molesters or vicious rapists. Satanists do not sacrifice young children or animals. The ninth and tenth of the Eleven Satanic Rules of The Earth forbid this, in fact, animal sacrifices are primarily used in the Afro-Caribbean syncretistic religions such as Voodoun, Candomble', and Santeria. Child Sacrifices are used in Television and by journalists to improve ratings. A Satanist does not practice baby breeding or child molestation. Evidence does not support what is said to occur. If the number of murders said to be committed by Satanists' was accurate some bodies would have been found by now. Members of the Church of Satan are involved and advanced exactly as their own desires, abilities, and accomplishments dictate. There are no set activities, meetings, or contacts. A new member comes into the organization ideally with his or her own goals and plans of achieving them. When being brought to the church of Satan new members are told to not let anyone tell you what to believe or what to do. Advice or recommendations are one thing; orders or commands quite another. Remember that you are a free being, not a pawn in someone's power fantasy. They believe the weaker elements of society should serve the stronger elements of society or perish. Satanists support any means of returning to the order of Darwin's Natural Selection Process, this is inclusive of elimination of welfare to selective sterilization of those weaker elements. Weak elements are determined by performance and intelligence, not race or religion. So where does Satan come into all of this? Satanists believe Satan (and other gods) is not so much an entity as a force of nature. These gods are not all concerned with the life of mortals. Satan is a very powerful word that serves as an isolation between Satanists and society. It is this separation that a true Satanist appreciates and holds dear. the separation of a society where the strong and willing work for what they need and want but are forced to support the weak through welfare and charity. Satanists' know their opinions may not be politically correct, but they still obey the laws governing man on this planet and they expect the same protection under the laws as other minorities, races and religions. There are several divisions of the believe systems of various "Satanic" groups. Satanism has changed so much from it's original form. For instance a group that are

3 Cases of Mixed Metaphors

3 Cases of Mixed Metaphors 3 Cases of Mixed Metaphors 3 Cases of Mixed Metaphors By Mark Nichol Efforts to describe something idiomatically with the use of metaphor- a word or phrase that figuratively provides an analogy- more than once in a sentence will likely distractingly interfere with reading comprehension, so avoid using more than one metaphor in a sentence, or at least ensure that they are complementary. Discussions after each example in this post explain the difficulty of using two metaphors, and revisions suggest a solution. 1. What you hear symbolizes something ominous- impending danger lurking just beneath the surface, which has been hanging over our heads in recent years. The metaphors in this sentence come at the reader from both directions, with an allusion to subterranean peril and an indirect reference to the anecdote of the sword of Damocles, in which a king suspends a sword over a courtier’s head by a single hair to teach the man a lesson about the peril of being in a position of power. To avoid this discordance, the metaphors should be consistent in imagery: â€Å"What you hear symbolizes something ominous- impending danger lurking just beneath the surface, which has percolating in recent years.† (Percolating is also a metaphor, but such one-word analogies embedded in our language do not distract as easily as more vivid imagery, and the verb is concordant with the preceding metaphor.) 2. These actions resulted in a significant redirection of market focus and gave the firms a ringside seat when the proverbial music stopped. â€Å"A ringside seat† refers to achieving a privileged position (literally, a front-row seat at a boxing match), and the phrase about music alludes to surviving a round of the game of musical chairs, in which competitors circle a group of chairs that numbers one less than the number of participants and vie to obtain a seat when music that is briefly played suddenly ceases, causing one person to be disqualified in each round. Although both metaphors deal, in a sense, with attainment of privilege, the contexts are different, and one is best abandoned in favor of the other: â€Å"These actions resulted in a significant redirection of market focus and gave the firms a ringside seat when that shift occurred.† 3. The same division within the party that derailed healthcare reform could also rear its head with respect to tax reform.   The reference to figurative derailment is at odds with the clichà ©d metaphor of a threatening creature preparing to strike. Again, sacrifice one metaphor for another (preferably, replacing the clichà © with a straightforward verb): â€Å"The same division within the party that derailed healthcare reform could also occur with respect to tax reform.† (An attempt to match the derailment reference with another train-related metaphor will only call attention to the symmetry at the expense of the point of the sentence.)

Auditing Literature review Example | Topics and Well Written Essays - 250 words

Auditing - Literature review Example lified public accountant to an organization during the period of the audit engagement but are not connected to an audit or checking of an organizations financial statement. Auditor’s independence is the foundation of the auditing profession (Miettinen, 2008). Non-audit services largely affect the auditor’s independence. Due to the non-audit, services conducted in an organization, the accuracy of the information given by the auditors’ will increase compared to when they give information without non-audit services being done (Adelopo, 2012). There also exists a relationship between non-audit service fees and auditing quality. Non-audit services increase the quality of auditing in any organization (Reckers, 2003). The quality of auditing is increased, as the auditors are aware that the documents in the organization have been scrutinized. Since the no-audit service and auditors pass through the information, number of errors containing the information is reduced (Beattie, Fearnley, and Hines, 2011). Non-audit services and auditing independence are somehow related. The non-audit services affect the independence of auditing directly as they affect how the audit is carried out. The practices are similar as both try to improve the quality of information given by scrutinizing the information of the financial statements and the report given to shareholders (Dunne and Morris, 2008).

Restoring the British Museum. Main change challenges faced by the Neil Essay

Restoring the British Museum. Main change challenges faced by the Neil McGregor from the time of his appointment in 2002 - Essay Example However, the charismatic manager exhibited numerous management and leadership qualities that countered the opposition thereby earning him the success he enjoyed. Among the major factors that threatened his success included the lack of motivation exhibited by the employees. The fact that the museum had announced a job cut that would affect more than one hundred and fifty employees of the museum demoralized the entire workforce owing to the anxiety that resulted from the announcement. Motivation refers to a set of mindset that influences the performance of the human resource in an organization. The state of the mind is a fundamental influencer of productivity since it varies the fears an individual feels thereby affecting their productivity (Mills, 1988). The other major challenge the manager faced at the facility was the cultural clash in the existing management. The structure of management that included two managers both of whom were competing for roles and responsibilities created a major confusion in the organization’s culture that threatened the future of the museum. Coupled with the unmotivated employees, Neil McGregor inherited a stagnating facility that would take more than zeal and charisma to revitalize. Neil McGregor inherited such a sluggish workforce. This became his greatest challenge since he could not reverse the mindset of the employees. One hundred and fifty is such a large number that would not only decrease the size and efficiency of the workforce but also threatened the success of Neil McGregor. Prior to his arrival at the facility, the museum had about one thousand five hundred employees. Despite such a large workforce, the rumor of one hundred and fifty employees losing their jobs threatened most of the employees who thus became withdrawn and unmotivated. Each of the employees moved about sluggishly waiting for their retrenchment. The fact the employees who faced the job cut had nothing to lose makes them among the most difficult to

Byzantine up to the Early Reniassance Essay Example | Topics and Well Written Essays - 750 words

Byzantine up to the Early Reniassance - Essay Example Their paintings thus entailed naturalism and reality (Lahti 10). These artists comprised Donatella, Masaccio, Giotto, Brunelleschi, among others. Their art sought to refute global gothic style diffusing during that era. Scientific relations also comprised a feature of their paintings. Their art exemplified lots of skill and prowess. The art entailed lots of influence emanating from Roman Catholic. Another feature eminent throughout the images would be use of extra light and color in paintings. This exemplifies that the paintings depicted a higher quality compared to those produced in premature renaissance. Artist enjoyed lots of funding from wealthy families and religious persons. The sponsors chipped in coupled with the target of developing the sculptures and painters while portraying their skill. Multiple Choice Questions 1) Donatella encompassed a Florentine A) Painter b) Drawer c) Singer d) Ruler 2) Renaissance expounds a practice enveloping A) Eastern Rome B) Central Rome C) Wes tern Rome d) Europe 3) Early Renaissance entailed artists that refuted art that was a) Gothic b) Natural C) realistic d) Revolutionized 4) Artists during early renaissance included a) Brunelleschi b) Leonardo da Vinci c) Michelangelo D) Raphael First Image (1427) Figure 1: The Holy Trinity, Florence. Retrieved from http://www.italian-renaissance-art.com/Masaccio.html The painting above encompasses an esteemed masterpiece during 1427. This entails one of Massacio’s works. This entails a Holly Trinity painting for Novella church that encompasses its situation in Florence. Unlike prior painting, this painting entails depictions of revolutionized art. One indispensable feature would be improved use of light. The painting differs from earlier ones with reference from the ideology that the latter just showed lines. The lines showed demarcations that unveiled different partitions of a drawing. More so, the image encompasses relations to Roman Catholic convictions (Lahti 15). This dr aws explanations from the ideology that Roman Catholic entailed a distinct religious culture. Another similarity to images and arts of this era entails their refutation to Gothic styles. This expounds that Massacio refuted the diffusing ideologies of Goth existing during that duration. Therefore, he sought making art that depicted reality and naturalism. In addition, the painting depicts human bodies in a rational manner. This draws basing from the ideology that earlier paintings comprised of images that entailed no clarity. The imager also entails depictions of societal beliefs. This exemplifies that this art correlates to Eastern Rome’s catholic beliefs. Second image (1415-1416) Figure 2: â€Å"St. George† Retrieved from http://www.italian-renaissance-art.com/Donatello.html The image above depicts a sculptor that owes its making to a renowned Florentine. Donatella encompassed a sculptor that made history in Rome. His art entails illuminations of sculptures that depic ted lots of humanism. The sculpture above represents Saint George. Unlike the belief by Catholics that saints ought to depict solemnity, Donatella refuted those arguments by making Saint George appear serious and prepared to combat the enemy. Similarities between Masaccio and Donatella’s images The images depict lots of realism (Lahti 20). This gains explanations from the ideology that they entail real features comprising a being’

The Post Office

The Post Office The Post Office is a group of three core businesses that form the UKs national postal system. It operates as a public corporation and is owned, but not managed, by the Government. Its businesses are: Royal Mail: the letters business, Post Office Counters Limited, the retail Business and Parcel force, the parcels business. It also runs Subscription Services Limited, which provides a portfolio of services to UK businesses. The group as a whole has recorded a profit for the last 19 years, and is one of the few national Postal administrations to operate without government subsidy. In 1994, following a review set up two years earlier, the Government published a discussion paper that set out proposals for the future of The Post Office. Following a prolonged and intense public debate the Government decided, in 1995, to drop plans for Royal Mail/Parcel force privatisation from its then current legislative programme but in the following year announced it was relaxing some of the financial restraints to allow The Post Office businesses to compete for new business. A brief history of the Post Office The origins of the Post Office can be traced back to 1482 when couriers carrying pacquets (royal messages) were granted the power to requisition horses and guides. By 1660 control of The Post had passed from the monarch to Parliament with the creation of the post of Postmaster General. From the introduction of the uniform penny post in 1840 the Post Office grew and took on new responsibilities until by the 1950s about 1/3 of all civil service staff were employed by the Post Office. In October 1969 the Post Office ceased to be a government department and became a corporation. The responsibility for the day to day management passed from the Postmaster General to the board of the newly constituted corporation, although the new Minister for Posts and Telecommunications still retained control of the Post Offices budget. Further reform followed in 1981 when post and telecommunication were separated and The Post Office Corporation was divided into The Post Office (responsible for postal services and National Giro Bank) and British Telecom (responsible for telephones and telecommunications). Again the argument behind this change was that it would make the Post Office more suited and responsive to the needs of the commercial modern world. The Post Office delivery services survived the mass privatisations of the 1980s. However, British Telecom was privatised in 1984 followed by the National Girobank in 1989. Although, The Royal Mail is the letters division of the Post Office, It is obliged to provide a universal service at a uniform price. This is achieved through cross subsidisation of more costly services by less costly and a monopoly on deliveries of letters costing less than  £1.00. The Royal Mail has a network of approximately 100,000 post boxes and employs approximately 80,000 postmen. Post Office Counters Ltd is a network of approximately 20,000 sub post-offices. They are mostly privately owned and run by agents (sub-postmasters), many are also shops. They sell stamps and provide other services such as pensions, etc. Parcel force is an independent division of the Post Office that operates without a monopoly and in direct competition with a number of private sector companies. Parcel force employs approximately 13, 00 staff, has 165 depots and a fleet of approximately 9000 vehicles. The reason to tell this entire story to explain the changes went through in this organisation by the time requirement. Description of nature of information systems: A Local Area Network (LAN) had been introduced in the Newcastle upon Tyne postal district 18 months earlier and was intended to link together different locations in the Newcastle area and to provide a gateway to other Post Office LANs nationwide. Initially use of this system was restricted to senior (board level) managers but with the impending restructuring and expected privatisation use of the LAN was extended to other levels in the organisation. At the initial time of the interviews there were 37 terminals in the Newcastle area and 6 at remote sites. The Newcastle LAN could also be used to link to another 20 Post Office LANs in different parts of the country. The system integrated elements of personnel, administration, recruitment and data on human resource utilisation with data on costing and the volume of business transactions. What is a network? A network is a generic term for any computer based communications system that links together a number of computers and other devices. A network may be called a LAN (Local Area Network) or a WAN (Wide Area Network). LANs are networks that connect several devices, usually through a single cabling system, within a clearly defined area such as a single building or a group of adjacent buildings. WANs on the other hand are networks used to distribute data around sites that may be scattered across or single country or the entire world. WANs may be composed of interlinked LANs and may use a number of different communications links (e.g. satellite and telephone lines) to join their component parts. Networks may take many forms although, conceptually, they only consist of two parts. Description and analysis of functional use of information systems: The networking software defines the logical structure of the network: it controls and co-ordinates certain activities in a group of otherwise independent processors (network stations). At the heart of each network is the fileserver. The fileserver treats the network stations as if they were storage peripherals (e.g. disk drives) while the network stations treat the fileserver as if it were a hard disk reading from it and writing to it as required. To each machine it appears as though the data had simply come from a disk drive. Communications software and the physical link both the network stations and the fileserver run communications software to send data to each other through the physical link. The physical link, i.e. cabling system, defines the physical structure of the network while the communications software carries the data along the physical link; together these two things act as a medium for the communication between fileserver and network station. However networks can facilitate communication between people as well as machines. Electronic mail, diaries and teleconferencing facilities can be used as a medium for communication, control and co-ordination between people. For example, e-mail allows asynchronous communication between individuals or groups and also enables the efficient distribution of text based memos or messages to a group, or groups, of recipients. Assessment of current use of information systems Security and ease of management: Networks, by their nature, impose restrictions on certain actions by certain users at particular times (e.g. two users cannot write to the same file at the same time). This greatly simplifies file management and can provide several layers of additional security, e.g. passwords and or access only via dedicated terminals. Networking software can also provide alarms and audit trails to assist dealing with security problems if they do occur. Resilience Networks are virtually unaffected by local damage. If a network station breaks down it can be simply removed without any disruption to the other users. If the data has been backed up then no data need have been lost; the user can simply move to another network station. The fileserver on the other hand is the hub of the network; if this ceases to function the whole network stops. However, once again, if all the data has been backed up and good recovery procedures exist networks can even survive a fault at the fileserver. Efficient use of resources: Networks make a more efficient use of resources as they allow the apparently simultaneous use of one application by several users. The most obvious example of this is the shared use of programs such as word processors and spreadsheets. These will only need to be installed once on a file server and can then be used on any number of machines. Networks also allow the cost of expensive but infrequently used items, such as specialist printers or tape drives, can be shared between a large numbers of users. Similarly old, unusual or otherwise obsolescent equipment can also be made use of in this way.
