Is Time Real Essay Example for Free

Is Time Real Essay Is Time Real The aspects of time that we can understand are only based on what we can perceive, observe, and calculate. Every day we look at our watches or clocks. We plan our day around different times of the day. Time tells us when to eat, when to sleep, and how long to do things for. Is time real? To answer this question, let me explain what time is first. Time is defined as a measured or measurable period, a continuum that lacks spatial dimensions. This broad definition lacks the simple explanation that humans are searching for. There are many scientists, philosophers, and thinkers who have tried to put time into understanding terms. In the following paragraph, I will discuss the meaning of time perceived and theorized by two of the greatest minds of human kind ? Einstein and Kant. Albert Einsteins theory of relativity (study guide, 53) came up with the idea that both space and time were relative to the observer, or the state of motion of the observer (Broadcast). If there are two chairs, and you see someone sitting in one, when you turn away, you can not be sure that he or she is still there. You also can not be sure that they are not in two chairs at the same time, or what point in time they are in them. This all leads up to Einsteins theory that time is relative. What Einsteins theory seemed to tell us was that time is not absolute and universal. It can be changed by motion. Each observer carries around his own personal scale of time and it does not absolutely agree with anybody elses. However, some philosophers have argued that all time is unreal. Kant, for example, claimed that time both the subjective time we experience as flowing, and objective time as the fixed series of all events ? is a construct of the human mind (Manuel Velasquez, 244). For Kant space and time are not real things, but are modes of experience. Kants solution was to say that there is something in our mind, that makes everything that we experience to our sense be located in time so that the physical world is simply bound to be temporal because of the way our minds works (Broadcast). From my point of view, time is definitely real, only our experience of time is subjective. For example, we see a train with blue color followed by yellow color followed by blue and so on. We will at first be able to distinguish the blue from the yellow as the train starts moving. After a while, the train moves very fast that the sequence appears to be simultaneous to our eyes and mind and we see green. We can see time is real because blue follows yellow, but our perception of time is subjective because we dont see a sequence of blue following yellow, but something else entirely. In conclusion, time is not easily explained or understood by anyone. Einstein and Kant have expanded their minds by coming up with possible theories for the unknown. We can theorize, and calculate our own, but I think it will always be an unknown. The mysteries of the universe will in my opinion be just that, a mystery. Resources: Manuel Velasquez.

Effects of Excessive Petroleum Use

Effects of Excessive Petroleum Use Researches shown that in 2014, the world’s oil consumptions would reach 90, 78 million barrels per day. This indicates the importance of the oil in every country, both developing and developed countries. But in the same research, the supply of oil in one day in the world’s only estimated about 89, 74 million barrels per day, which means the supply will soon can’t afford the usage of oil in the world. This lack of supply can easily cause the exhaustion of petroleum and then it may lead to the power crisis. Petroleum supply exhaustion is one of the biggest problems in every country in the world, governments and scientists are trying to find ways to solve this issue. Amongst some effort that have been done to solve the supply exhaustion problem, this essay will argue about the degradation of the oil’s quality in some area and improve the quality is one of the best way to put an end to the hardness. Litten by oil was shown to have been used in the ancient Chinese. In the 8th century, the oil production had appeared in Iraq where people use pitches, a waste of petroleum to cover the streets. The first oil drilling was said to be around Baku, Azerbaijan. But it was not until the beginning of the 19th century that oil exploitation was strongly developed. At that time, the main fuel was the spermaceti but it was too expensive, none can afford it except the rich people. Although the price was very high but it had a very bad smell so that people want to find a replacement. In the middle of the 19th century, scientists found many ways to exploit the crude oil efficiently. The first modern drilling was in 1859 in Pennsylvania and it put a start to our current petroleum industry. As the crude oil is becoming one of the most important thing for our lives, it is being overexploited that lead to the supply exhaustion, one of the biggest and the most significant problem in petroleum industry. Over two centuries, trillion of oil barrels have been exploited, this number is not decrease but it increase significantly in the last two centuries and it’s becoming more and more. In some researches, scientists have pointed out that people used 30 billion barrels of oil per year; this horrible number shows that people are using too much oil but the supply and the reserves do not enough for us to use. According to the chart posted by Michael Morrison, the world supply and demand change repidly from 2008 to the first quarter of 2012, in 2008 and 2009, the demand and supply are very similar, but from the first quarter of 2010 to the first quarter of 2012, the demand always higher than the supply, even in some times, the differences reach 3 million barrels per day. With those evidences, the exhaustion of petroleum is becoming more and more serious. It is said that the lack of petroleum supplement is becoming more and more severe, and the causes of this problem is observable. Supply exhaustion come from both subjective and objective reasons. One of the reason why the petroleum supplies deficiency than the need is the usage of everybody in the world. As we have known, oil is used in most aspect of our life. People use petroleum or at least its waste to process it into products such as all leather foot, aspirin, waxen, chewing gums, and the most important apply of oil is fuel and gas; two of the most important power resources in the world. Since oil has become so important and the products which made of oil are becoming more useful, its high usage is understandable. We all know that it is easier to use than make, so that the supply always have to follow the need. The next main reason is about the use of the low quality crude oil. Low quality oil contains a great amount of sulfur, a toxic. According to Greg Karras, low quality oil can increase the greenhouse gas emission by as much as 17 %-40 %( Environ. Sci. Technol, 2010, 44). Some statistics have shown that Middle East is the region which has the most oil reserves in the world, but in some others statistics; the Middle East’s oil has the worst quality (G. Houlton, 2010). Most of the imported oil in the world comes from Middle East, which means we are using the low quality oil; this can cause significantly bad effects to our health and our environment. This can cause severe damage to the supplement of oil. Petroleum industry is not the only one that suffers from this, industries, people, social and even some governments also have trouble with this hardness. The aspect which will be affected the most serious is the economics. The most adverse effect is price of petroleum will have to be increased. If the price of petroleum is increased, since some industries have to use the products of petroleum as its materials, those industries will be in difficulty and with the higher and higher prices of crude oil, the producer’s prices raised significantly. It is followed by every other product must increase their price which lead to the restructuring of the economics and damage directly to the life of the social groups, products excess and even economics crisis ( Kiseok Lee, Shawn Ni, 2002). Plus, the countries those who focus on export petroleum such as Russia, Arabia, UAE, etc†¦ will be suffered from the raise of the price of petroleum for some countries can’t afford it. Furthermore, some countries have the intensifying unemployment rates and the taxes collected from citizens are lower because of the low employment and with the raise of the petroleum, those countries now have to face a very pernicious problem. To sum up, the lack of supply of petroleum has many causes. Although the impact of this problem at the present is not so serious and some solutions have been given out. However, people have to overcome this soon to prevent the problem from being severely. In the case of the lack of supply, people have to take action to control this problem, not only during the event but also after it. These are the most fundamental solutions. First, the government should control the usage of petroleum in each country. There are four main ways I want to suggest to reduce the usage of petroleum. Petroleum is known to have been the most used fuel in the world and most of the products of petroleum are used to make fuel. In the event of the number of the vehicles are rising, the world need more and more fuel to run those vehicles, which lead to the explosion of the oil demand. In order to solve this, the scientists have found some replacements for the petroleum such as biofuel, power source from sticks; carrots; †¦ (R.J.Kopp, 2006). Apply those replacements in the real life will surely ease the pressure on the petroleum supplement. The next way to reduce the usage of petroleum in life is the change in people’s using habits. People have used some organic, green products instead of products made from oil. Avoid using personal vehicles to travel from place to place and replace it by cycle or public transport, using packaged without plastic products; recycle and re-use bottles, etc†¦ (J. Lucie, 2010). Plus, some industries which use petroleum as its raw materials should decrease the usage of petroleum and manipulate some others resources as the main raw materials (NASEO). It will followed by the lowered of the demand. In addition, to reduce the use of petroleum in the world, scientists should find alternatives to petroleum products. There are many sources that can replace the petroleum and petroleum-based products like electric, natural gas, hybrid gas, bio-diesel; a little known replacement to diesel fuel which is made out of used vegetable oil and can be burned in diesel cars and in home oil burners (Baltimore Monthly Meeting of Friends, Story Run, 5116 N. Charles St., Baltimore, MD 21210). I would add that photovoltaic, passive solar, wind turbines and some others renewable fuels can be used to replace fuel. These are some alternatives for petroleum fuel which people can use it to reduce the usage of petroleum. However, most of those alternatives are little-known ones, only a little people know about it, then how can they use it There should be some propaganda campaigns that help the people know about the situation of the petroleum supplement then show them the advantages of using the alternati ves for oil, this could help people reduce using petroleum as their most important power source. Last but not least, a very effective way to reduce the use of petroleum in people and teen is some programs that the government should set up such as â€Å"weekend without oil†. This is a program which was set up by dosomething.org, an organization help young people to tackle against some impact from their own behaviors and habits. These programs should aim to helps people to recognize the ways that their daily routines help increase the oil consumption and provide the people how to avoid it (C. Tackett, 2010). This is not only help to reduce the use of oil but also make the people to be more active with some outdoor activities such as walk or ride a bike,†¦ Although all these solutions are very effective, but it’s also have some disadvantages. There’s one most optimal solution that I have given, and it is:† people should use alternatives fuel†. This is the most effective way to restrict the usage of petroleum; it’s also the best way to improve the quality of our environment which is being severely damage by the over-using of petroleum. In this solution, people can reduce their petroleum usage by using others kind of power source such as solar energy, power of the wind, biofuel, biodiesel†¦ and especially fuel for driving vehicles. As most of the amount of petroleum is used as the fuel to run the vehicles, changing the fuel of the vehicles is the best ways to reduce the petroleum usage, which biodiesel and solar energy can be the best one. Using these alternative can help reduce the reliance on petroleum of most of the country in the world. Plus, some alternatives are renewable resources while petroleum is non-renewable resources, which mean we can use as much as we can without worry about the exhaustion of those resources. Furthermore, those alternatives’s bad effects are extremely small while petroleum can cause huge damage for our environment, every year; using and exploiting petroleum emit 381.740.601lbs of toxic air pollution, 3.3 trillion lbs of CO2 (J.Sandry,2013). Using alternatives for petroleum is very useful and it’s also the easiest way to reduce our reliance on petroleum so that we can solve the petroleum-exhaustion problem, and even the environment problems. Biofuels is an example, these are result from the photosynthesis of plants which convert solar energy into chemical energy, its green and renewable though their slightly less energy than oil and gasoline but much cleaner (ecoreps). Some researches shown that using solar energy instead of petroleum in 25 years can help reduce 199.679lbs of CO2, 2316 trees can be planted with the surplus and help the drivers saving 208.166 miles driven (RGS energy,2014). This way is not being limited in any country but for every country in the world, everyone can use these replacements, it’s even cheaper than the cost of the petroleum, then why shouldn’t people use these alternatives, for both themselves and the world. However, the only downfall of this solution is that it can’t be spread through some dev eloping countries, people should find some way to widespread these alternatives to developing countries to help them. In order to reduce petroleum usage and saving our environment, replace petroleum in most of aspect in our lives is the best way to achieve our goal. In conclusion, supply exhaustion in petroleum is a significant problem in every phase of petroleum industry, but this is a most severe time when the surplus between supply and demand is at the highest ever. Industries, power, products, etc†¦ now have to rely too much on petroleum and its waste which is the most fundamental reason for this problem. This reliance does not damage the petroleum industry with the depletion of supply but also damage the economics with the raise of the cost of petroleum. However, the most significant effect is the damage our environment with the use and the waste of petroleum. In that consequence, people have to reduce their use of petroleum to save them from the reliance on petroleum. The best way to reduce the use is using alternatives, solar energy; wind energy; biofuels†¦ are very effective alternatives that people should consider to use them instead of using too much petroleum. This is not only to save the petroleum industry but also our envi ronment. Everyone should join hand to solve this problem.

Google And Yahoo Search Engine

Google And Yahoo Search Engine Web search engines are keys to the immense treasure of information. Dependency on the search engines is increasing drastically for both personal and professional use. It has become essential for the users to understand the differences between the search engines in order to attain a higher satisfaction. There is a great assortment of search engines which offer various options to the web user. Thus, it is significant to evaluate and compare search engines in the quest of a single search engine that would satisfy all the needs of the user. The main problem is facing by people, which search engine is very useful for finding reliable, relevant and fresh results. There are plenty of search engine are available for searching but, this dissertation will cover which technology are running behind Google and Yahoo!! search engine. Google and Yahoo! have their own algorithm for indexing the website. Introduction of Search Engine: In simple words a Search engine is software that searches through a database of web pages or web resources for a piece of information, keywords, concepts etcà ¢Ã¢â€š ¬Ã‚ ¦ There are many types of Different Search Engine available in Market. for example msn, Google, Yahoo!, ask etcà ¢Ã¢â€š ¬Ã‚ ¦ C:UsersJIMIT DOSHIDesktopnew dwnlddifferent-types-of-search-engines_4823.gif.jpg Figure: 1 Different Search Engine To define the concepts more descriptively we can say that Search engine is a computer program that searches for documents containing words or phrases of interest to users .The search engine itself is a virtually powerful workstation-class machine that searches a database of information collected from the Internet. Primarily software program called robots or spiders that crawl through all the files on the Internet and download them into a searchable database .These works as indexes to the literature available on the network. In the context of the Internet, Search engines usually refer to the World Wide Web and not other protocols or areas. Search engine is helpful for identifying sources, establishing notability, checking facts, and discussing what names to use for different things. There are a number of search engines available on the web. Most of the Search engines provide website reviews and homepage services in addition to keyword searches. But, in this present study two most popular search engines have been studied in terms of its available web resources with reference to Physics-India in Google and Yahoo!. Introduction of Google Google is one type of web search engine. When user wants to find something around the world using internet at that time Google comes into the picture. Google Search is the most-used search engine on the World Wide Web. So Google provide the entire information base on keyword which is put by the user in to search box of Google search engine. When user entry any keyword for search Google display all the related result of the keyword. Introduction of Yahoo! Yahoo! is one of the best known and most popular Internet portals. Originally a subject directory of sites, it now is a search engine, directory, and portal. To go to the Yahoo!! portal and main starting point, use www.Yahoo!.com. For direct access to the search engine, usesearch.yahoo.com and for the directory use www.dir.yahoo.com. This review primarily coves the search engine features. Use the table of contents on the left to navigate this review. Literature review and proposed overview: Search engine technology has had to scale dramatically to keep up with the growth of the web. In 1994, one of the first web search engines, the World Wide Web Worm (WWWW) [McBryan 94] had an index of 110,000 web pages and web accessible documents. As of November, 1997, the top search engines claim to index from 2 million (WebCrawler) to 100 million web documents (from Search Engine Watch). It is foreseeable that by the year 2000, a comprehensive index of the Web will contain over a billion documents. At the same time, the number of queries search engines handle has grown incredibly too. [1] In March and April 1994, the World Wide Web Worm received an average of about 1500 queries per day. In November 1997, AltaVista claimed it handled roughly 20 million queries per day. With the increasing number of users on the web, and automated systems which query search engines, it is likely that top search engines will handle hundreds of millions of queries per day by the year 2000. The goal of our system is to address many of the problems, both in quality and scalability, introduced by scaling search engine technology to such extraordinary numbers.[2] With the explosive growth of World-Wide-Web (WWW), publishing document on Internet has become more popular.But how to locate what we need in the ocean of information is an increasingly important and urgent problem. To simplify the problem of getting relevant results based on the search query, the Internet search engines were created that allowed searching a lot of information from the World-Wide-Web in the form of Web pages [3]. Search engines are among the most successful application on the Web today. They act as a system for searching the information available on the Web by automatically searching the contents of other systems and creating a database of the results [4]. The most famous search engines include AltaVista, Infoseek, Google, and MSN. They provide good searching ability by indexing more pages on the Web and maintaining the updated indices in their databases. Despite so many search engines are available to help user in finding the information of their interest, searching on the Web is not an easy task. The problem is due to the vast amount of data on the Web and its rapid updating and growth[5]. History of Search Engine The first Web search engine was Wandex, developed by the World Wide Web Wanderer in 1993. Another very early search engine, Aliweb, also appeared in 1993 and still runs today. One of the first engines to later become a major commercial endeavor was Lycos, which started at Carnegie Mellon University as a research project in 1994. Soon after, many search engines appeared and vied for popularity. These included WebCrawler, Hotbot, Excite, Info seek, Inktomi, and AltaVista. In some ways they competed with popular directories such as Yahoo!!. Later, the directories integrated or added on search engine technology for greater functionality. In 2002, Yahoo!! Acquired Inktomi and in 2003, Yahoo!! Acquired Overture, which owned AlltheWeb and AltaVista. In 2004, Yahoo!! Launched its own search engine based on the combined technologies of its acquisitions and providing a service that gave pre-eminence to the Web search engine over the directory. Before the advent of the Web, there were search engines for other protocols or uses, such as the Archie search engine for anonymous FTP sites and the Veronica search engine for the Gopher protocol. Recent additions to the list of search engines include a9.com, AlltheWeb, Ask Jeeves, Clusty, Gigablast, Ez2Find, Teoma, WiseNut, GoHook, Walhello, Kartoo, Snap and Mamma . Market Cover of different Search Engine :C:UsersJIMIT DOSHIDesktopnew dwnlduse of search engine chart.gif Figure: 2 search engine market As per above figure: 2 Google and Yahoo! cover most of the market of the world. Both have more popularity then other search engine. Google beat the Yahoo! at some level History of Google Search Engine: Google was co-founded by Larry Page and Sergey Brin while they were doing their Ph. D. at Stanford University in 1998 and was officially launched in the fall of 1999. This is a straightforward engine that does not support advanced search syntax making it very easy to use and retrieves pages ranked on the basis of number of sites linking to them and how often they are visited, indicating their popularity (ibid). It claims that 97% of the users find what they are looking for. C:UsersJIMIT DOSHIDesktopnew dwnldgoogle snapshot.png Figure:3 Google home page overview Its success was based in part on the concept of link popularity and PageRank. How many other web sites and web pages link to a given page is taken into consideration with PageRank, on the premise that good or desirable pages are linked to more than others. The PageRank of linking pages and the number of links on these pages contribute to the PageRank of the linked page. This makes it possible for Google to order its results by how many web sites link to each found page. Googles minimalist user interface was very popular with users, and has since spawned a number of imitators. Google has been estimated to run over one million servers in data centers around the world, and process over one billion search requests and about twenty-four petabytes of user-generated data every day Instead of ranking pages, this technology uses an algorithm that follows links on a webpage to find other pages that link back to the first one and so on from page to page. Features: Google includes the following most important features: Cached page archives. Result clustered by indention. Result displayed option, from 10-100. Google Search Supports: Implied Boolean (+)sign, (-) sign. Double quotes () for phrases. Stop words. Other Search Options Available with Google: I m Feeling Lucky (goes directly to top ranked site in query) Google scout (bring up list of related sites) Uncle Sam (Searches govt. and Milsites) Search within results option Field searching with link only. History of Yahoo! Search Engine: Yahoo! was co-founded by Stanford University Graduate students Jerry Yang and David Filo in January of 1994.Yahoo! is a subject Directory and also a commercial portal compiled by human. It is oldest as well as largest directory on the web. C:UsersJIMIT DOSHIDesktopnew dwnldsnapshot of yahoo.gif Figure: 4 Yahoo! search engine Yahoo! allows the user to put a search query, its strength lies in the categories and each that can lead a user step-by-step to the desired subject category. Structure: Yahoo! is hierarchically organized with subject catalogue or directory of the web which is browseable and searchable. Links to various services are accomplished in two ways such as by users submissions and through robots that retrieve new links from known pages. Yahoo! indexes web pages, UseNet and e-mail address. Features: Topic and region specific Yahoo! Automatic truncation. No case sensitivity. The syntax that Yahoo! follows for searching is fairly standard among all search engines. Search Option: Users can browse Yahoo!! Simply by clicking on the various categories listed on each page, or can search Yahoo!! By entering a word into the search box that appears on every page in the directory. Again one can combine the two strategies and can browse and then search or search and then browse. Other Search Options: Yahoo!! News User may combine any of the query syntax as long as the syntax is combined in the proper order, which is +, -, t: , and *. If Yahoo! does not find any matching entries, pertaining to a query, in its main database, the query will automatically be transferred to the Inktomi database, a search engine that automatically crawls the text of the entire web. Inktomi database contains results for literally millions of individual web pages. Yahoo! thus looks for information in: Yahoo!! Categories. Websites listed in Yahoo!. WebPages indexed by Inktomi. Working of Google Search Engine: google_search_strategy1_thumb.png Figure: 5 how work Google search engine Google Search (or Google Web Search) is a web search engine owned by Google Inc. Google Search is the most-used search engine on the World Wide Web, receiving several hundred million queries each day through its various services. The order of search results on Googles search-results pages is based, in part, on a priority rank called a PageRank. Google Search provides many options for customized search, using Boolean operators such as: exclusion (-xx), alternatives (xx OR yy), and wildcards (x * x). The main purpose of Google Search is to hunt for text in Web pages, as opposed to other data, such as with Google Image Search. Google Search provides at least 22 special features beyond the original word-search capability. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie showtimes, airports, home listings, and sports scores. There are special features for dates, including range, prices, temperatures, money/unit conversions, calculation, package tracking, patents, area codes and language translation of displayed pages. Data about the frequency of use of search terms on Google (available through Google Adwords, Google Trends, and Google Insights for Search) have been shown to correlate with flu outbreaks and unemployment levels and provide the information faster than traditional reporting methods and government surveys. PageRank Googles rise to success was in large part due to a patented algorithm called PageRank that helps rank web pages that match a given search string. When Google was a Stanford research project, it was nicknamed BackRub because the technology checks backlinks to determine a sites importance. Previous keyword-based methods of ranking search results, used by many search engines that were once more popular than Google, would rank pages by how often the search terms occurred in the page, or how strongly associated the search terms were within each resulting page. The PageRank algorithm instead analyzes human-generated links assuming that web pages linked from many important pages are themselves likely to be important. The algorithm computes a recursive score for pages, based on the weighted sum of the PageRanks of the pages linking to them. PageRank is thought to correlate well with human concepts of importance. In addition to PageRank, Search Results: The exact percentage of the total of web pages that Google indexes is not known, as it is very difficult to accurately calculate. Google presents a two-line summary and also a preview of each search result, which includes a link to a cached (stored), usually older version of the page. Googles cache link in its search results provides a way of retrieving information from websites that have recently gone down and a way of retrieving data more quickly than by clicking the direct link. This feature is still available, but many users are not aware of this because it has been moved to the previews of the search results presented next to these. Non-index able data: Despite its immense index, there is also a considerable amount of data available in online databases which are accessible by means of queries but not by links. This so-called invisible or deep Web is minimally covered by Google and other search engines. The deep Web contains library catalogs, official legislative documents of governments, phone books, and other content which is dynamically prepared to respond to a query. Google Optimization: Since Google is the most popular search engine, many webmasters have become eager to influence their websites Google rankings. An industry of consultants has arisen to help websites increase their rankings on Google and on other search engines. This field, called search engine optimization, attempts to discern patterns in search engine listings, and then develop a methodology for improving rankings to draw more searchers to their clients sites. Search engine optimization encompasses both on page factors and Off Page Optimization factors (like anchor text and PageRank). The general idea is to affect Googles relevance algorithm by incorporating the keywords being targeted in various places on page, in particular the title element and the body copy (note: the higher up in the page, presumably the better its keyword prominence and thus the ranking). Too many occurrences of the keyword, however, cause the page to look suspect to Googles spam checking algorithms. Google has published guidelines for website owners who would like to raise their rankings when using legitimate optimization consultants. Functionality: Google search consists of a series of localized websites. The largest of those, the Google.com site, is the top most-visited website in the world. Some of its features include a definition link for most searches including dictionary words, the number of results you got on your search, links to other searches (e.g. for words that Google believes to be misspelled, it provides a link to the search results using its proposed spelling), and many more. Search Syntax: Googles search engine normally accepts queries as a simple text, and breaks up the users text into a sequence of search terms, which will usually be words that are to occur in the results, but one can also use Boolean operators, such as: quotations marks () for a phrase, a prefix such as + , - for qualified term or one of several advanced operators, such as site:. The WebPages of Google Search Basics describe each of these additional queries and options . Query expansion: Google applies query expansion to the submitted search query, transforming it into the query that will actually be used to retrieve results. As with page ranking, the exact details of the algorithm Google uses are deliberately obscure, but certainly the following transformations are among those that occur: Term reordering: in information retrieval this is a standard technique to reduce the work involved in retrieving results. Stemming is used to increase search quality by keeping small syntactic variants of search terms. There is a limited facility to fix possible misspellings in queries. Working of Yahoo! Search Engine: Yahoo!! Search is a web search engine, owned by Yahoo!! Inc. and was as of 2009, the 2nd largest search directory on the web. Yahoo!! Search, originally referred to as Yahoo!! provided Search interface, would send queries to a searchable index of pages supplemented with its directory of sites. Yahoo! does not use Web Crawling for retrieving the results. It uses Inktomi for getting results of keywords which are not found by the Yahoo! In 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo!! Search. Search Technology Acquisition: Seeking to provide its own search engine results, Yahoo!! acquired their own search technology. In 2002, they bought Inktomi, a behind the scenes or search engine provider, whose results are shown on other companies websites and powered Yahoo!! in its earlier days. They purchased Overture Services Inc., which owned the AlltheWeb and AltaVista search engines. Initially, even though Yahoo!! owned multiple search engines, they didnt use them on the main Yahoo!.com website, but kept using Googles search engine for its results. In 2003, Yahoo!! Search became its own web crawler-based search engine, with a reinvented crawler called Yahoo!! Slurp. Yahoo!! Search combined the capabilities of all the search engine companies they had acquired, with its existing research, and put them into a single search engine. The new search engine results were included in all of Yahoo!!s sites that had a web search function. Yahoo!! also started to sell the search engine results to other companies, to show on their own web sites. In 2007, Yahoo!! Search was updated with a more modern appearance in line with the redesigned Yahoo!! home page. In addition, Search Assisst was added; which provides real-time query suggestions and related concepts as they are typed. In 2008, Yahoo!! Search announced the introduction of a new service called Build Your Own Search Service, or BOSS. This service opens the doors for developers to use Yahoo!!s system for indexing information and images and create their own custom search engine. Study of Web Resources of Google Search Engine: Below Table gives a description of Web resources on Physics India retrieved through the Google Search out of 100 links. The following figure shows the Graphical representation of Web resources. Result: The analysis of the data available with the below table shows that most of the Web resources under the search term Physics India retrieves the pointer pages (links to websites on the same subject) and achieves 67% among all the other kinds of resources. Secondly, relates to the journal articles by 26% of retrieved output. And the lowest percentage of search results deals with research news, news clips, databases and conference papers .Above table shows the graphical representation of the retrieved output through Google.

Similarities of Google and Yahoo! Search Engine Several similarities of Google and Yahoo! Search engines are found after visiting both websites and testing with a query. First of all, both search engines give great advantages for users; they provide optional tips or techniques to help users search efficiently. Some similar tips are found. The first technique is using specific and unique words to describe what we are looking for. If the keywords are more general or ambiguous words, the large number of irrelevant feedback documents will be retrieved. Another technique is using quotation marks around keywords so that the searchers can find the exact words and narrow the number of search results. There are several techniques to narrow the search results, including (1) limiting sites/domain as .com, .edu, or .gov, (2) specifying types of files to .htm/.html, .pdf, .doc, and .txt, (3) using operator (-) before the word that we do not need it appears in the search results, (4) using operator (+) before the word that we do need it in the search results, and (5) using Boolean operators like AND, OR, and NOT to specify searching terms. The other techniques are using additional options to get more relevant search results. For instance, users can specify updated files, countries, languages, and number of results per page. These techniques from both search engines are very helpful for users to retrieve more precise results. For example, giving the query like swine flu + unt , both search engines returned many web pages about swine flu with the word unt, which is the University of North Texas. This can reduce not only the time process the search engines, but also the time to fine the best precise search results. The second similarity of these search engines is that they provide many categories for the search results, such as web, images, videos, shopping, news, and sports. With selecting a specific category like images, a user can retrieve only images on the webs. Users can also define specific type of file like .pdf, .doc, and .jpg, which helps users to get more precise and reduce time process. Third, when typing the keywords, Yahoo! suggests the full key words as well as Google. This helps users to select the full query as fast as possible. Suggesting the full keyword is a smart task for both search engines because it is an Artificial Intelligent part, which tries to guess users what the next word of the query is. For example, when typing swine, both search engines suggested the word flu as the next word. Next, the search results of both engines are quite similar patterns, which show the title in the first line, the brief description of webpage in the next several lines, and the URL or webpage s address. This snippet for each web result is enough information that a user can quickly scan and move to find information from other web pages in the ranked results. Last but not least, after submitted a query, both search engines immediately returned the relevant results, along with the large total number of websites retrieved. This shows the ability and efficiency of both search engines. Obviously, with these advance tips for both search engines provided on their web interface, they become the most top-two popular use over the others in the world. These are the great search engines that people use to find enormous information on the Internet since they provide the ways to retrieve more relevant search results. (B.)Contrast between Google and Yahoo! Search Engine Interface, Design, and Layout : The most obvious difference between these two Web sites is about the Interface, Layout, and Design of the pages. Google offers a very Clean and simplistic interface, whereas Yahoo!!s is busy and cluttered. Simple design should always be used to avoid complexity and confusion to the user. When a user is not required excessive text and images, they will feel more at ease and comfortable while using your Web site. Ultimately, a simplified interface means that the Web site will be accessible to all types of people with different skill levels, thus increasing the potential for a significant user return. Another key aspect of Design and usability is defining or understanding the purpose of the Website. Due to the simplistic nature of the Google Web site, it is quickly apparent to the user that the

Electronic game is a famous entertainment among human no matter in which ages, the transformation design of video games and computer games had gone through a lot of changes since the first ever invented. The difference between the video and computer games is not much but the physical appearance. Video game is built through devices with a console that require a television to be played with. Compare to computer game that required a computer to run the games and with features of online gaming which video game doesn’t support. Computer game allow players to interactive to each other when play online while video game only allow interaction between friends and family. Over the years, computer games become popular compare to video games because of the variety games supported by computer where video games only support by one system and only applicable on their own game creation. Video game is an electronic gaming that display on a video display or television screen or the latest devices such as PSP and Nintendo. In the early 40s, the world first video games called â€Å"Cathode-Ray Tube Amusement† had been invented by Thomas T. goldsmith Jr. and Estle R. Mann that made a starting point to video games. The evolution of video game had been transform from graphic paper till the 2D graphic and better 3D graphic such as Microsoft XBOX, Wii and Sony Play Station. On the other hand, computer game known as PC game had not much different than video game which computer game is design to be use on a computer but not a video display television screen with keyboard as the controller. The first computer game was invented on 1952 called â€Å"TicTacToe† by A.S. Douglas on an EDSAC vacuum-tube computer. Recently in the past few years, this gaming field had be... ...t game presence positive impact on students. They conduct the research with a computer based game call â€Å"Fire Captain† that allow student to comprehend the role as a fire fighter. The result had brought out a conclusion where students who played the game beneficially learned problem solving skills, increase critical thinking and better understanding as a role of fire fighter. In addition, educational gaming guide students to a better management skills and earlier age of leadership practice through the game. On the other hand, video and computer games powerfully changed the world trend where children nowadays cannot live without a technological devices or computers game. This issue had become concerned among parents and societies where games might consists potential harmful materials such as violence, aggressive and over fascinating towards games.

NHS Balanced scorecard Essay -- British Health Care, Politics

This part of the assignment will discuss balanced scorecard that has been implemented by UK National Health Service (NHS), how it has influenced and impacted upon the performance measures of this organisation. ‘Since its launch in 1948, the NHS has grown to become the world’s largest publicly funded health service. NHS employs more than 1.7m people and deals on average with 1m patients every 36 hours. It is also one of the most efficient, most egalitarian and most comprehensive. Even though NHS services in England, Wales, Scotland and Northern Ireland are managed separately and each might have some system differences, they remain similar in most respects and belong to a single, unified system. The NHS core principle is that good healthcare should be available to all, regardless of wealth.’ (NHS, 2010) Success of NHS depends on how well the organisation balance quality and customer (patient) satisfaction with adequate financing and long-range goals. Health care organisations such as NHS must deal with government oversight, managed care, new technologies, and increasing pharmaceutical prices. The NHS has adopted a performance measurement system that is based on the concept of balanced scorecard in order to obtain a broader view of performance within the organisation (Department of Health, 2001). Although, measuring performance evaluation of health care system could be difficult, it can on the other hand serve several purposes and can help facilitate change and improvements in the effectiveness and quality of health care. It seems peculiar to focus on performance measures in organisation such as NHS, but even NHS is facing increasing competitive pressures when considering ageing populations increasing demand, improved treatment... ...t in public/patient accountability, service efficiency and staff involvement to a highly prominent level. Government has developed ‘Star Ratings’ system which monitors improvements in accountability measures. The experience of the ‘Star Ratings’ system in respect of service efficiency indicates that it is prudent to act pro-actively rather than re-actively. It is vital to consider that the Government is expecting demonstrable improvements in health services rather than rhetoric alone (Radnor and Lovell, 2003). ‘Though it is intricate to demonstrably prove in quantitative terms that the balanced scorecard can deliver efficiency improvements at the start of its implementation, it can be shown in quantitative terms that a well designed fully cascaded balanced scorecard system should address the needs of a health care system. ’ (Radnor and Lovell, 2003, p. 105)

A good man is hard to find :: essays research papers

â€Å"I just know you’re a good man! You’re not at all common!†   Ã‚  Ã‚  Ã‚  Ã‚  Just some of the last pleading words of the grandmother in the story, â€Å"A Good Man is Hard to Find† by Flannery O’Connor. In the story, the author uses colloquialism, point-of-view, foreshadowing, and irony, as well as other rhetorical devices, to portray the satire of southern beliefs and religion throughout the entire piece.   Ã‚  Ã‚  Ã‚  Ã‚  Flannery O’Connor lived most of her life in the southern state of Georgia. When once asked what the most influential things in her life were, she responded â€Å"Being a Catholic and a Southerner and a writer.† (1) She uses her knowledge of southern religion and popular beliefs to her advantage throughout the story. Not only does she thoroughly depict the southern dialect, she uses it more convincingly than other authors have previously attempted such as Charles Dickens and Zora Neale Hurston. In other works, the authors frequently use colloquialism so â€Å"local† that a reader not familiar with those slang terms, as well as accents, may have difficulty understanding or grasping the meaning of the particular passage. O’Connor not only depicts a genuine southern accent, she allows the characters to maintain some aspect of intelligence, which allows the audience to focus on the meaning of the passage, rather than the overbearing burden o f interpreting a rather â€Å"foreign language.†   Ã‚  Ã‚  Ã‚  Ã‚  Another device not frequently used before O’Connor is the transition between third-person to first-person point-of-view, the first-person being through the grandmother. In the beginning of the story, she describes how the each of the characters feel towards taking a trip to Florida, as well as hint at the relationships they hold for one another. Then the narrator goes on to describe the grandmother’s personal thoughts and feelings throughout the trip, as well as how she thinks towards the end of the story. We first see the first-person point-of-view when the narrator tells how the grandmother did not want to leave the cat at home alone because he would miss her too much and she feared he would accidentally asphyxiate himself with the burners on the stove. The reason this particular part of the story is considered first-person narration is because it goes directly into the mind of the grandmother, telling why she brought the cat along with her. We als o see this first-person narration when Baily’s wife is consistently referred to as the children’s mother, rather than by her name or as Baily’s wife.

Educational Change

Topic: Analyse a story about an educational reform happened in a secondary school and comment its effectiveness based on the organizational theories. ————————————————- 1. Introduction The Education Commission Report No. 7 released in September of 1997 suggested to build a quality culture in schools(EDB, 1997) . Since that, schools and education institutions of all levels experienced changes and reforms in various scale and kinds. Schools are no longer stable and predictable places.Schools and school systems had gradually turned into a mode of modern organization: departmentalized and bureaucratized in last century. However, in last two decades, the reform in education has been launched in all over the world. It is clearly because of the needs of new millennium – we are moving or even already in the postmodern age now. The postmodern age world is fast, compressed, com plex and uncertain(Hargreaves, 1994). Schools are places for preparing the generations of the future, therefore, changes are essential to all educational organizations.In this paper, the story about the culture reform happened in a one-through school will be told to provide a case-study of how an evolution occurred in an educational system. The dimensions, type and effectiveness of reform will be discussed. 2. Literature Review We know change is essential to postmodern education system. But change for change is not help and not what we want. An educational change, is assumed to help schools to achieve their goals more effectively, theoretically. It is important to bear in mind that change is a process, not an event(Fullan & Stiegelbauer, 1991)Literature provides the category for the change. Superficial changes , like changes in content, structure or policy, which induces improvement on something currently doing, are classified as first order change. Those changes occur on those fund amental, for example, goals and roles, are classified as second order change. (Cuban, 1988) â€Å"Educational change depends on what teachers do and think-it's as simple and complex as that†(Fullan, 1991, P. 117). While what the teachers do and think is a reflection of their basic assumption and belief or the change is just superficial.It is vital to understand the culture of the organization and how it affects the norms and behaviors. (Stoll & Fink, 1996). There are fundamental relationship between culture and effectiveness(Rossman et al. , 1988). Though school culture is powerful, schools are more comfortable to first order change than second order change (Cuban, 1988; Fullan & Stiegelbauer, 1991). But first order change would not be internalized without second order change(Leithwood, Aitken, & Jantzi, 2001). 3. A Story about Changing the School School X was a band three secondary school in a very new developed district in Hong Kong.Included School X, there were two seconda ry schools in the district, which with population of around 60,000. In the fifth year of school X being set up, a vice-principal of another school (for convenience, we called him/her W) of the same sponsoring body was sent to this school. At this time, school X was obviously in adverse position compared with another school in the district. Almost all higher banding students chose another school, over 80% of students of School X is in band 3 while over half of these students were in territorial bottom 10%.Most of the middle managers were not functioned. Teachers with negative attitude were majority. Some teachers had passion and willing to pay effort for students, but because of the norm and culture, what their effect was confined. Students lacked of interest and motivation in their learning, not mentioned to have any confidence and expectation on their own academic performance. The impression of School X was terrible in the community. â€Å"Fortunately†, the number of classes and teaching group of school X were small and still expanding with he increase of population size of the district. W already knew she would be vice-principal of school X for only one year and then would be promoted to be principal in the next year. W took the year of being vice-principal of school X to familiarize with the setting, the norm, the culture and social relationships in this school. The story of change began in the next year, W became principal of School X†¦Ã¢â‚¬ ¦ 4. Analysis of the changes Changes is a process, most researchers stated there are three broad phases involved: Initiation, Implementation and Continuation.Fullan (1991) added the idea of outcome to the process to give a come complete picture. Since the progress of educational reform occurred in School X involved numerous innovations each affected different domains of the school (Surely, this is common to all educational changes), the followed analysis will be written according to the framework shown in F igure 4. 1 . This framework is modified from the simplified overview of Fullan(1991), the titles of the points I will highlight for each phase are added to the box below each phase.Figure 4. 1 A simiplified overview for the process of change in School X No doubt, the new principal took a critical role in the initiation of change. But any educational change in school should involve all parties in school, therefore, the innovations are always not only from the principal but should be from all a stakeholders, especially from teachers and students. A group of teachers with similar belief with W were selected to act as a workforce to improve the performance and effectiveness of the school.Three teachers from this group became the new leaders for the academic, discipline and guidance department. The replacement was a quite severe step in school system. But it was also an effective way to remove the potential resistance to the change. The concept of workforce group was a successful startup . It involved teachers, the staff that would execute the change, as McGregor (1957) argued about the Theory Y of management, innovations and motivation are present in people, the manager only needed to make it possible for eople to recognize and develop. On the other hand, only small group of teachers were included in the workforce. Huberman and Miles (1984) argued that large-scale participation at the initiation phase is not productive and too much energy would be exhausted for pre-action discussion. The new department leaders, with W, leaded the group of workforce to review the rules and regulations, and drew up some new practice, then discussed these practice with the whole teaching team.Actually, the changes in rules and regulation were small, the focus was on the execution of these rules and regulations should be uniform and coherent. Though at this time the scale and degree of change on school was small, but it just like a pilot step for the consequence wave of reforming. Befo re these practices were introduced, W shared the bad news about the terrible intake of S1 in that year, over 70% of new comers are from the group of territory bottom 10%, with all teaching staff in the meeting. She also showed the data about the trend of population and development of the district in the meeting.What she pointed out was : more and more secondary schools were setting up in the district, all of them would be competitors of their school; the worst thing was, though the student population was going up that time, but it was not a long story, the population would decline after several year; they would finally face the crisis of shrink in number of classes, even being forced to close. W had capitalized on propitious moments for the change. The circumstances that call for change was dramatized to win the support and cooperation of teachers (Trice & Beyer, 1993). The results of pilot trial were satisfied.Though everything still had great room for improvement, but all of them seemed to be in progress. W celebrated the success with all staff (both of teaching and non-teaching). In the next year, some changes induced ‘externally† happened: Regional/national level: The ECR no. 7 recommended the idea of using performance indicators to assess the quality of school. This aroused the concern about effectiveness and quality of schooling in society. Local level: * School X moved to a brand-new campus equipped with extra facilities. * School X was changed from a traditional secondary school to a one-through school.School X now had its first class of primary one. These â€Å"external factors† provided good ground to fertilize the consequence changes,. Among various of innovations, the setting up of first quality circle took a critical role in the reform of School X. The quality circle was formed by a group of ten young and passionate teachers. Teachers in the circle were assigned to be the class teachers of S2 classes (the form with terrible S1 i ntake). They were empowered to design and execute the setting and rules (academic and discipline aspects) work on the whole form.Recalled the organization Y described by McGregor (1957), this was another example about â€Å"using† the motivation and potential for development already in people to direct behavior toward the organizational goal. The outcome of implementation of quality circle was inspiring. The success of the quality circle was originated from it decentralized the power to and enlarged the job of some staff in relative low position of the school hierarchy (by experience, status and responsibility), and caused a sense of satisfaction in their social and egoistic needs. The success of quality circle created a dramatic change in the belief of teachers.After that, quality circles were set up for each form. It was institutionalized as a school policy and long term practice. After years of implementation, the behavior and academic performance of students had obvious i mprovement. The job satisfaction of teachers was greatly improved. Most items in the APASO and KPM, especially those related with the teacher and students relationship, have index better than the territory norm. Now, School X is categorized in band 2. Fullan(1991) listed 9 critical factors organized into 3 main categories affecting implementation. Figure 4. shows the interactive relationship of them: In the case of School X, for the characteristic of change: the need of change was obvious, the goal of change was clearly explained to all staff, the individual complexity on most staff was not too high to create resistance. In addition, as most rules and regulations remained the same, the practicality was acceptable. For the local characteristics, though the district and community factors could not be examined, but the principal and teachers showed positive attitude to the implementation, especially after the success of trial done in the first year.By cultural perspective, Rossman et a l. (1988) identified the culture change processes to three types: Evolutionary, Additive and Transformative, depended on the degree of explicit, conscious focus on cultural change. The change in School X involved explicitly implementation of policies and practices, it should belonged to additive or transformative. While as the cultural norm was changed in a quite big scale with some severe means (replaced the heads, restructured the school system, etc. ), the reform of School X was classified as transformative.The developmental age of School X affected the cultural change in it as well. Stoll and Fink (1996) described the mechanisms likely to bring about change in three developmental age of school: Birth and early growth, Midlife, Maturity and /or stagnation and decline. School X should belong to Midlife stage, and the description about change through explosion of myths, quality circle was an exact example of this. The idea about creating new myth also echoed by(Trice & Beyer, 1993) , the effectiveness of myth to change cultures was affirmed in his article. 5. Comment on its effectiveness 5. Classical theory vs. Human resources theory The definitions of effectiveness of the change/reform were varied. The implementation of change in School X relied on application of human resources theory mostly. Compared with the classical theory, human resources theory took much more time and sometimes the outcome may be misled to be deflected from the organizational goal as it emphasized on the managing by objective instead of control with assumption about people had motivation already inside(McGregor, 1957). However, for the setting of school, human resources theory is much more appropriate.Though in earlier of this paper, the characteristic of schools in postmodern age was subjected to change; on the other hand, schools should be stable enough to let the teachers and students feel safe and secure. The scientific management emphasizes on selecting themost qualified employees to perform the job, this may not fit for the situation of school. Furthermore, the classical theory also included sense of bureaucracy. Bureaucracy was a common practiced in modern school for many years. However, this perspective may not suitable for the postmodern age school nowadays.Bureaucratic schools are close-ended, static and balkanized, in contrast, what we need now are open-ended, evolving and collaborative learning organizations. 5. 2 Cultural perspective Rossman(1988) argued culture defines effectiveness. In this part, I will comment on the effectiveness of the change in School X by cultural perspective. 5. 2. 1The classification of change by levels of culture The culture can be distinguished to three levels , on the base of basic assumptions, values and behaviours are observable manifestations (Schein, 1985). In Table 5. 1, the change of School X in each level of culture was described.Table 5. 1. Description on the change of School X by levels of culture. Level| Descrip tion| Artifacts and creations| The appearance of students was improved. The behavior of students inside and outside the classroom was improved. The academic performance of students improved. The intake of the school improved. | Values| The senses of belonging of students increase. The self-esteem and confidence of students improved. The satisfaction of teachers about the job improved. | Basic assumptions| The impression of community on School X changed to be more positive. The mission and goal of the school became clear and evolving.Senses of collaboration and cooperation were developed among teachers and students. Teachers’ belief migrated from â€Å"students cannot be changed† to â€Å"students can be changed through education, it just needs time and effort†. | 5. 2. 2Assessing Amounts of Change To understand the amount of change, the process can be described along four dimensions: Pervasiveness, Magnitude, Innovativeness, and Duration (Trice & Beyer, 1993). T he pervasiveness in change of culture was high. All the main business within the school was affected. The behavior of majority of teachers and students were changed.Surely, some of them tried to ignore the change, but the proportion was small. The magnitude of the change was high. The old negative values and belief evolved to much more positive ones. The innovativeness was not very varied in this case. Actually, the change in rules, rites and regulation were limited. The practices implemented were also common in other schools. But the idea of decentralization of power with quality circle was innovative among Hong Kong schools. Finally, the duration, it was high and actually, School X is still evolving even now, as a culture of evolving was developed. 5. 2. 3Definitions of effectivenessAccording to the research work of Rossman et al. (1988), from the cultural perspective, the definitions of effectiveness changes refer to the norms, beliefs and values of organizations. Took Rossman â €˜s suggestion, I tried to analysed the effectiveness of reform in School X by five criteria. Firstly, the definition should be multisided; Both of the academic and the non-academic achievement should be considered. The academic performance of School X was improved and the band of it was promoted. On the other hand , the sports teams and volunteer team had outstanding performance in region. Second,  the  concern  for  order  is  essential to  all  schools.Ordered environment facilitate learning and teaching, it also brought about the sense of respect. The behavior of students was improved. The lesson time spent on dealing with the problem of classroom management was greatly reduced. It brings about the achievement of the third criterion – the quality of teaching; as teachers had more time for preparing teaching activities with higher quality. The focuses of professional training activities included the new teachers training programs and school-based trainin g activities were migrated from classroom management to some more academic purpose.The fourth one is to establish appropriate expectations for intellectual outcomes. Except the first two years of implementation, the main concerns of School X in the followed six years all about enhancing the learning and teaching effectiveness. The performances of students in public examination also have been evaluated and discussed both in the meeting at subject levels and school level. Finally, value the diversity. School X developed teams for students with different education needs, for example, special education needs, non-native Chinese speakers, gifted, etc. 6. 2. Three perspective of culture The culture strength can be described by three perspectives: Integration, Differentiation and Fragmentation(Martin, 1992). Before the implementation of change, School X should be described as differentiation, teachers , those willing to pay effort and those not, worked on their own style, belief and goal. Conflicts between colleagues happened frequently. The reform caused the culture of School X evolved much more coherent, but the characteristics of sub-groups were still kept, so it is much more likely to be fragmentation rather than integration. . 2. 5Limitations of the cultural perspective on evaluating the effectiveness of change Culture is powerful, it affects the whole setting and every members of the organization. But the cultural perspective is only a way to give better insight of the organizational culture and also about the change. It never gives any fast and promising way for change. One can have a better planning and more precise expectation on the response of the members of organization to the implementation of change. 6. End of story? Never ended†¦.As we said in the start of this paper, schools nowadays are providing training to people who will deal with the fast, complex and mercurial life in the postmodern age. Schools that keep static and satisfy with their past achievement are no longer good schools. The senses of changes should be rooted within every stakeholder of the schools and education system. The cycle of planning, implementation and evaluation now was very familiarized by each educators in every levels of institutions, it is not just for documentary purpose and dealing with school external review, it is also a key for the keeping the schools change to right way.References Cuban, L.
