Advantages And Disadvantages To Javascript Computer Science Essay

Advantages And Disadvantages To Javascript Computer Science Essay The ability to make site inspection data and real-time response, it should use the technology called AJAX Asynchronous JavaScript and XML. AJAX is a name for a group of technologies, including JavaScript, CSS and XML. It can run in Web browsers, enhanced interactivity, ease of use and speed. JavaScript may be a client-side scripting language developed by Netscape development. JavaScript is published since 1996. At the time, it supports Netscape Navigator 2.0 and Internet Explorer 3.0. XML (Extensible Markup Language) is designed to improve the data description, storage and exchange. It is published by the W3C in 1998. Its conceptual design and hierarchy node to provide good support for data storage. CSS (Cascading Style Sheets) is a style sheet language. It is used to separate the data layer and display layer in HTML. In other words CSS can provide a solution to be defined and looked at the web page format. The most important is the use of AJAX, use XHR (XMLHttpRequest) for playing Web server. XHR object created when a user will establish a connection to the Web server. XHR object occurs between the Web browser and Web server. XHR object will listen to the web server updates the Web page production part of the update. XHR then be adopted by the update to the web browser to update the Web page is part of it. This mechanism successfully reduced bandwidth usage and data processing. Widespread use of AJAX interactive Web pages, such as Google Maps, Google search suggested that the stock price quote. In our system, we will use JavaScript for validation, because JavaScript is a scripting language. JavaScript is the ability to use the function to verify the clients data input incorrect data and we want. For example, if you enter the correct date, month and year. In addition, JavaScript can prevent users from submitting data, if the data does not meet the system asks. In order for the site have the ability to validate data and respond in real time, it was a technology called AJAX (Asynchronous JavaScript and XML) to use. AJAX is a name of a group of technologies, including JavaScript, CSS and XML. It could run on a web browser and increase interactivity, user friendliness and speed. JavaScript could be a client-side scripting language developed by Netscape. JavaScript has been published since 1996. At that time, she supported Netscape Navigator 2.0 and Internet Explorer 3.0. XML (Extensible Markup Language) has been design, improve data description, storage and exchange. It published in 1998 by W3C. His concept nodes and the hierarchical structure also provide support for data storage. CSS (Cascading Style Sheets) is a style sheet language. It is used to separate the data layer and layer display in HTML. to provide other word to define a CSS could be fixed method and format to search the site. The most important use of AJAX is playing with XHR (XMLHttpRequest) to deal with web server. A XHR is made, user must connect to the Web server. The XHR object is passed between web browsers and web servers. The XHR object is heard on the Web Server Update Web site update a part. Then XHR will be going in the update to the web browser on the part of the web site to renew. This mechanism successfully, the bandwidth decreases with and data processing. AJAX has been cited widely by using interactive Web page, such as Google Map, Googles proposal and the share price. In our system, we will use JavaScript to do the validation, because JavaScript is a scripting language. JavaScript is able to function, but want that data, client input with real data confirm we are not. For example, it is input the correct day, month and year. In addition, JavaScript could prevent users from sending data when the data was not met, the system inquires. Pic 2.2 Create the variable At the beginning, the script would built a lot of variables that we will use (Pic 2.2). Pic 2.3 The validation function Then, we shall use the procedure to do the validation (Pic 2.3). On line 19, the code was used to begin checking by if loop with the conditions. The code on line 22 alert user à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"Please select date for meter reading!à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚ , if user have not enter the day. From line 25 to 41, the function was setup to notice user whether they are input the incorrect year, day, month, also the meter reading. Pic 2.4 The validation to the meter reading From line 52, the JavaScript will check the meter reading input. It will alert if user input the meter reading is less then previous or it is not a number. Pic 2.5 These code will disable the submit button From line 120 to 136, JavaScript will have the result from the script we have mention above. If user input incorrect data, the submit button will gray out to prevent user to press it. If the information is correct, the function will change the button to normal status and user can click it. Pic 2.6 The submit button The script of the line 147 to 160 on the send button. The Send button is with JavaScript (line 152), are playing to validate information. Since there is, if the browser do not play with JavaScript, allow line 155-158 users submit button without JavaScript. With JavaScript, there are some advantages and disadvantages. On the negative side, there are security and reliability problem. Because JavaScript runs on the client computer, they will be used in a position for malicious purposes such as: Dead code insertion code conversion, register re-allocation Some people stop running JavaScript, it will affect the system running. In addition, the results of its portable, it is fully operational and rely completely on the client side web browser. That is, when client browser does not support JavaScript, or not enough new version of some script failed in the current. Although JavaScript has some weaknesses, there are many positive feature to help developers become the first choice. First, JavaScript is not on the server side to load the current resources and increase server capacity to save. In other words, client JavaScript functions can immediately instead of waiting to respond Server. Second, JavaScript is relatively easy to learn and implement. It is an open source high-level language is, it is easy to implement, compared to other programming languages such as Python, Perl, C # Finally, a well-tolerated JavaScript language. It may be written in other web page in another language, like PHP and Perl. It may interact with other language for a variety of applications to play well. Finally, AJAX (JavaScript and XML in particular) offer the ability to validate our system, greatly reduce the occurrence of bad data, do. And cost reduced compatibility with PHP much development time. Finally, because it can run on the client side, saving them directly to server computing resources. It indirectly reduce administrative costs, hardware investment costs and save development costs.

Influenza and its Effects :: Journalism Media Studies Health Influenza Essays

Influenza and its Effects The latest outbreak of "Spanish Influenza" continues to have a significant impact on life both in London and throughout Europe. The economic consequences are troubling as more and more workers from textile houses, mines and other areas where people are working in enclosed and confined spaces succumb suddenly to the disease. In some cases the onset can be as little as two hours. Industrial areas like London and the Midland areas of Nottingham, Leicester and Northampton have been especially hard pressed. While rarely fatal in the middle-aged, the symptoms of influenza are still dramatic and usually keep the patient out of work for a number of days. However after this period it disappears as swiftly as it came. Already burdened by the demands of wartime production industry has taken a heavy blow. Despite effective treatment with quinine Influenza is spreading faster than doctors can keep up, and indeed now there is scarcely an area of the country left unaffected by it. In some p laces the number of workers affected is as high as 70 percent. This would be far worse for the Allies were it not that the Germans were also severely affected by this outbreak, as reported by correspondents on the Western front. Berlin is said to have upwards of 160,000 cases of influenza, half of which are children. This coincides with another influenza outbreak in India, which is depleting their work force in a similar manner to that in England. The current climate is exceedingly dry and hot and it is felt that this may be contributing to the spread of the illness. Before May few if any cases of influenza were reported in or around London or elsewhere in Europe lending credence to this association. Other nations in Europe are also significantly impacted and it is believed that this current outbreak came to Europe from the south and worked its way northwards, hence its characterization as "Spanish Influenza". The fact that half of the cases in Berlin are children is similar to the situation in England. In Birmingham several schools recently had to be closed due to influenza outbreaks and in Egham, Surrey one school reported 50 to 60 cases and another over 130. Again this is thought due both to the climate and the fact that the students are together indoors for extended periods.

Globalisation on Jamaica Essay

1. Causes of globalization affecting Jamaica: * For Jamaica, the main reason for globalization was darker. The energy Crisis of the early 1970s forced the Jamaican Government to take out loans from the International Monetary Fund and the World Bank to cover the rising expenses of fuel based imports. However they weren’t interested in cooperating with Jamaica in developing native infrastructure and resources, so they enforced a short-term repayment of the debt, budget cuts in areas supporting long term development, and removing all trade barriers that favored local industry and farming. Thus, this started the forceful movement of â€Å"globalization† in Jamaica. Three negative globalization cases with causes and effects: * The first one involved Jamaica’s dairy industry. Due to free trade agreements between the United States and Jamaica, dairy farmers in Jamaica had to directly compete with American farmers without any subsidy aid from the government. This resulted in the influx of cheaper powdered milk into Jamaica from the USA, destroying its entire dairy industry altogether and farmer selling cows to the slaughterhouse at a loss. The effect of globalization on Jamaica in this case, only fostered dependency on other nations rather than focusing on its own economic development. * The second case is caused by the â€Å"Banana Wars† between Europe and America. Britain had a long-standing trade agreement with Jamaica that favored their banana exports as a way of compensating for their legacy of colonialism. This brought about complaints to the World Trade Organization (WTO) by the USA backed up by large agricultural multinational corporations like Dole, Chiquita and Delmonte who at the time already had 95% of the world’s banana trade, citing it as unconstitutional and against WTO’s policy. The ruling of WTO in USA’s favor and an international penetration of trade into Jamaica’s biggest banana market ensured yet another downfall upon one of the country’s most profitable industries due to the lack of production efficiency. * The third case came about due to the increasing economic stagnation and poverty in Jamaica. To combat this, the government agreed to create Free Trade Zones in Kingston where governmental enforcement does not apply. Ships would unload materials cut in the USA and Jamaican workers would sew garments in huge textile assembly plants near the docks for Hanes, Brooks Brothers and Tommy Hilfiger at $30 per week. These wages were not enough to sustain their standard of living and when protests emerge, the owners simply closed down their shops and relocated to Mexico, where a cheaper work force can be found. This is an example of the â€Å"race to the bottom† stemming from the effects of globalized capitalism. As a result, it leaves Jamaican citizens with lose or lose situation to either comply with unfair demands of employers or risk unemployment. 2. 3 examples in making Global Labour fair * In order to make Global Labour fair, three sectors of society, government, multinationals and civil societies must work together using their own sets of expertise. * The first example involves the Clinton administration regarding their stance on trade in 1996. The government provided the resources and the stage to gather civil societies such as human rights NGOs and trade unions, industry leaders, and its own department of labor to discuss about responsibilities in Global Labour. Civil societies present at the meetings gave ideas and insights about developing a global code of conduct in making labour fair as well as NGOs such as the Fair Labour Association provided awareness to the public about this matter. Then multinationals and industry leaders collaborated by implementing this code of conduct throughout their supply chain, terminating contracts from their suppliers if specific labour conditions are not met. Thus forcing the improvement of Labour standards. * The second example involves the New Zealand Recognized Seasonal Employers Scheme (RSE) to relieve seasonal shortages in the NZ horticulture and viticulture industry through an overseas labour force. The NZ government collaborated with other governments of the Pacific Island Regions to provide the legal requirements and immigration processes to facilitate the influx of workers. Businesses provide employment opportunities to the migrant labour force. On top of that, the government established an evaluation board which includes NGOs such as The New Zealand Council of Trade Unions to monitor key activities, evaluate outcomes and ensuring equity and respect for migrant worker rights. The collaborations between this three sectors of society (government, businesses and civil societies), made sure the benefits of global trade between NZ and Pacific Island Countries are mutual. * The last example includes the consumer goods multinational, Unilever who has taken significant strides in sustainable living regarding the 2001 mercury poisoning in Kodaikanal, India. NGOs such as Greenpeace were responsible of raising the issue to Unilever about scrap glass containing mercury from a Unilever thermometer factory being sold to a scrap dealer located nearby. This was a breach of Unilever’s procedures as workers’ health and then environment could be adversely affected. Unilever immediately closed the plant and removed the glass scraps and the soil beneath the scrap back to the factory. After negotiations, the Indian and US governments were responsible for providing Unilever legal permits for transporting and recycling these hazardous materials in the United States. The commitment of Unilever in ethical choices combined with the cooperation of civil societies and government organizations help prevent a potential fatal disaster that protected the welfare o f international labour. 3. Joseph Stigliz’s plans or conditions for making globalization work: * Eliminating or reducing poverty through more foreign assistance from advanced industrial countries to 0.7 percent of their GDP. Although I feel it’s a good idea for countries to redistribute wealth to disadvantaged nations in order to help make globalization work, I also think that imposing a general level of GDP assistance without consideration of a country’s individual economic conditions is unfair. In recent years, we saw the EU struggling with the financial collapse of Greece and the spread of investor uncertainty throughout its member nations. In this case, I felt that a reduction of foreign aid to focus on own problems is understandable because if developing nations lose a big trade partner such as the EU due this matter, results will be worse off in the long run for both parties. * Stigliz also suggested that this foreign assistance should be given in forms of grants instead of loans as well as and an altered approach to conditionality. I agree with this Idea as we saw earlier with Jamaica, most developing countries face the same problem of debt. Jamaica was forced by the IMF and the World Bank to open up trade barriers which forced dependency on other countries and the destruction of local industries. In addition to that, most governmental spending as well as any foreign earnings from exports is used to service this debt and its ever-growing interest instead of investing in the country’s long term development. This severely limits Jamaica from restarting its own economy, making globalization benefits one sided. * Making trade fair is also on Stigliz’s agenda. For example, removing trade tariffs of developed countries before imposing them on disadvantaged countries. I agree upon this idea and my argument can be built again based on the collapse of Jamaica’s agriculture industry. Potato, onion, carrot farmers have to directly compete with USA on a level playing field by removing trade barriers. However whether this situation is equal is questionable since the USA still maintains its large agricultural subsidies to aid its own farmers forcing down prices of their own produce. This renders Jamaican farmers uncompetitive due to high borrowing costs and lack of governmental aid. I feel this is unfair as this undermines the living standards of developing countries such as Jamaica and advanced countries only benefit from the trade. Lowering trade tariffs in developed countries first allows developing countries a fair chance to adapt to changes in the economy. * Stigliz acknowledges the limitations of liberalization are important. This is shown with the Washington Consensus based upon the concepts of liberalization forged between the World Bank, IMF and U.S Treasury which focused on the downscaling of government, deregulation, and privatization. Argentina who followed the Consensus initially had expansion of investment and export volumes. However what followed was a disappointing increase in unemployment, poverty, inequality, crime and violence. I feel that the reason the consensus failed to revitalize the economy was that they employed a one-size-fits-all mentality. There was an overemphasis on GDP measures which was inefficient in measuring living standards, growth sustainability and equality. Thus these factors are ignored and contributed to the failure of the policy. Therefore, I believe that understanding the local market, government and their individual economic problems apart from just imposing liberalization is crucial in order to make globalization work. * Stigliz mentioned protecting the environment is a growing concern for globalization. The success of economic development in China and India increases the need for energy usage and the use of resources. I agree with Stigliz’s notion that the world’s environment would not able to sustain this change. This year, there was a public outcry of Beijing’s air pollution when the Air Quality Index in the city saw a staggering reading of 755. As a comparison, any reading above 100 is considered hazardous for sensitive groups. This is attributed to the exponential increase in industrial activity in China. Although China benefits from an economic boom, I feel people must realize the cost of this endeavour to its citizens as it is irresponsible to ignore the negative health effects it causes. Enforcing people to work under these conditions is no different to taking advantage of unfair Labour consistently found within the poor working conditions in developing countries.

Ethical Dilemma Of The Antibiotic - 1657 Words

Cindy Valentin Ethical Dilemma Assignment NR-328 Pediatric Chamberlain University 05/26/17 INTRODUCTION This dilemma is for a 2 week old baby diagnosed with a gastrointestinal perforation two days after birth, which was later corrected with a temporary ileostomy.
