Soil Liquefaction Dangers During Arthquake

Ground shaking and shifting can cause major damage, tearing apart houses, buildings, and roads. †¢Flooding that arises from broken water dams or river levees is another hazard. †¢Tsunamis, triggered by an undersea earthquake as well as seiches – waves coming from lakes shaken by a temblor – can submerge whole communities, sweep away edifices, topple trees and drown people. †¢Fire is another seismic hazard. It can flare up from broken gas and power lines, or from overturned wood, coal, or gas stoves. But there’s another major earthquake danger that not many are familiar with. Soil liquefaction is a phenomenon that occurs when soil mixes with groundwater during a moderate or strong earthquake, turning the ground into quicksand in minutes. Soil Liquefaction in Low-Elevation Areas Because the soil must be saturated for liquefaction to take place, it is more likely to occur in low-lying areas that are near bodies of water such as rivers, lakes, bays and oceans. It happens most often in areas with sandy soil, where water takes hours to wend its way through the tiny channels of the mixture. More resistant to liquefaction are large-grained, permeable soils like gravel, which drains quickly, and clay soil, where particles are packed closely together.. It was in 1964, when earthquakes shook Niigata, Japan, and Anchorage, Alaska, that soil liquefaction was recognized as a major cause of earthquake damage. Scientists have since linked it to major historical earthquakes worldwide. Soil liquefaction inflicts great damage to property. Since the ground is too unstable to withstand pressure, anything resting above the mush—a building, a bridge, a house, a pier, a runway, a nuclear power plant, an earth dam—may lean, tip over, split open, or sink several feet. Ways to Reduce Soil Liquefaction Risks What can be done if a soil has been identified as susceptible to liquefaction? An undergraduate research paper written by Alisha Kaplan lists three ways to reduce liquefaction risks when constructing new buildings and structures. †¢Avoid building on liquefaction-susceptible soils. Besides soil tests, vulnerable places can also be pinpointed by investigating past events in an area. Soils that had liquefied in previous seismic events can liquefy again if another quake occurs. †¢Erect liquefaction-proof structures. If construction on weak soil cannot be avoided, the structure’s foundation should be designed to resist the damaging effects of liquefaction. The building must be made ductile, equipped with adjustable supports, and constructed to withstand large deformations and span soft locations on the ground. †¢Improve the soil. Improvements should increase ground strength, density and draining capacity. Installing vibroflotation, vertical wick drains, compact piles, and stone columns can lower the possibility of liquefaction. Soil liquefaction cannot be taken lightly, especially by those living in suspected liquefaction-prone areas. With earthquakes seemingly in the news more often, it serves residents and authorities alike to take a look around them and assess if they are standing on firm ground, literally. Taking safety measures in advance can save lives and property should a calamity strike.

Name and briefly describe the three basic processes of respiration. Ans:1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. Link to: 22. 3 Inhalation and exhalation 58. Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. Ans:Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse. Link to: 22. 3 Inhalation and exhalation Inhalation and exhalation, 22. 5: Oxygen and carbon and 22. 6: Respiration 59. In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue. In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. Ans:Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients). Other answers may be acceptable. Human a&P Ch. 22 Respiratory System Name:Â   Date:Â   Link to: 22.1 Inhaled air travels in the upper respiratory system 1.

Name and briefly describe the three basic processes of respiration. Ans:1. Pulmonary ventilation is the movement of air in and out of the lungs due to contraction and relaxation of muscles that control the size of the thoracic cavity. 2. External respiration is the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. 3. Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissues. Link to: 22. 3 Inhalation and exhalation 58. Describe the inward forces of elastic recoil, and explain why the lungs do not normally collapse during expiration. Ans:Elastic recoil is the recoil of elastic fibers stretched during inspiration and the pull of the surface tension of alveolar fluid. Intrapleural pressure is always subatmospheric during normal breathing, which tends to pull lungs outward and to keep alveolar pressure from equalizing with atmospheric pressure. Surfactant in alveolar fluid decreases surface tension to help prevent collapse. Link to: 22. 3 Inhalation and exhalation Inhalation and exhalation, 22. 5: Oxygen and carbon and 22. 6: Respiration 59. In chronic emphysema, some alveoli merge together and some are replaced with fibrous connective tissue. In addition, the bronchioles are often inflamed, and expiratory volume is reduced. Using proper respiratory system terminology, explain at least four reasons why affected individuals will have problems with ventilation and external respiration. Ans:Answers could include: reduced compliance (reduces ability to increase thoracic volume); increased airway resistance (decreases tidal volume); decreased diffusion due to increased diffusion distance, decreased surface area, and changes in partial pressures of gases (altering gradients). Other answers may be acceptable.

Government and Media in Cuba Essay

In between the Caribbean Sea and the North Atlantic Ocean lies the island of Cuba. It is a small island with a total land area of 110,860 square km, yet it is so powerful enough to catch the attention of United States and to strengthen its security measures. The country was first ruled by the Spanish government and its history was marked by revolutions and uprising. Finally, in 1902, through the intervention of the US government, Cuba achieved its independence from the Spanish rule. However, the proclamation of independence did not end the uprising and rebellious activities because the country was not freed from leadership of corruption and military-rule. The real independence, as recognized and celebrated by Cubans, was achieved when Fidel Castro took office. Fidel Castro was the leader of rebel army that has been fighting the corrupt government and established a communist form of government. At present, Cuba is under the rule of Castro and the state remains to be a communist government having three branches namely; the chief of state, legislative and judiciary. General Raul Castro currently holds the chief of state which is comprised of Council of State and Council of Ministers (â€Å"The World Factbook†). On the economic aspect, the embargo that has been imposed upon the country has not yet been lifted. Currently, Venezuela is the main partner of the country and the main source of its petroleum needs. The living standard also remained low as a result of the embargo and discontinuance of foreign aids from several countries (â€Å"The World Factbook†). However, it has agricultural, trading, industrial and manufacturing enterprises where it sources out its economic and financial needs. As of July of the present year, the country is occupied by an estimate of 11,451,652 people having different racial descent including Africans, Spanish, Westerns and Asians (â€Å"The World Factbook†). Despite changes that have been introduced in the country, there are still issues that have been bothering the nation and even its citizens. Through its communist form of government, many activities were hardly exercised by the citizens because of government suppression. The most suppressed and monitored activity is the expression of one’s thoughts and ideas. The right to express one’s self is being curtailed by the government especially when it contains ideas that are against the government. The role of media is to protect the government as it is founded only to voice out words that the government desires to hear. In contrary to the role played by media in many countries, the Cuban media does not serve as the voice and protector of the people from the government but as an ally of the state. The treatment of the media people is also despicable in the eyes of the international community and of the journalists themselves. Hence, this paper will present the relationship of the media and government as well as the role it plays in the country. Concomitant to that is the life of journalists under the communist government of Cuba. Role of Media Media has been recognized as indispensable tool in communication. Mass media, as defined, is â€Å"the technological means of sending information, ideas, opinion, etc. through the mass communication device to a diverse audience† (â€Å"Impact of Media on Culture†). Various means used by mass media in transmitting information effectively and swiftly includes television, radio, newspapers, magazines, and internet. Notably, internet has been the most preferred and ideal means of mass media because of its ability of reaching a wider audience and is laxly monitored. In addition, internet is most preferred because it does not require profession to enable any individual to express his or her ideas. Among other nations, mass media is recognized as the fourth department of the government because of the role it plays in the political and social aspect. The mass media usually fills in the gap between the government and the people. It voices out the sentiments or thoughts of the people to the government while it also brings to the people the sentiments and plans of the government for the country. In some instances, mass media becomes a watchdog against government abuses and activities that are definitely out of reason. Furthermore, mass media has continually become the source of information about things, persons, places, and events, among others. Due to the indispensable role of mass media in the society, it need to be free and not controlled by any person or agency nor can be regulated by the government. Instead, it should be free in order to properly carry out its objective. Apart from that, it should not be controlled to ensure its impartiality and neutral role. Historical Background of Media in Cuba The epoch of mass media in Cuba can be traced back during the Spanish regime. The history also of the country’s press has undergone five periods (Browning). The Colonial period which stated from 1723 to 1868 is recognized as the first period. During that period, the first newspaper entitled Gazeta de la Habana was released in 1782 and become the nation’s publication (Browning). In 1790, the newspaper was followed by the very first magazine entitled Papel Periodico de la Habana (Browning). Both were regulated by the Spanish government but enjoyed less restriction because of the French Revolution affecting the government power of Spain over Cuba. The second period began in 1869 when Independence was first craved for and ended in 1902. The period is also called the Independence Revolution (Browning). During that period, press was given full freedom purposely to win the support of the reformists. Eventually periodicals containing ideas about reform began to evolve which includes El Cubano Libre, Estrella Solitaria, El Mambi, and El Boletin de la Guerra (Browning). Notably, during the second period, more revolutionaries were inspired to fight for their independence through the influence of Jose Marti who writes in several newspapers such as Patria, La Nacion, and New York Sun (Browning). The second period was marked by independent exercise of expression through publications that is direct, immediate and constant (Browning). The third period started when called the Republican period which started from 1902 and ended in 1930. The third period was ruled under the dictatorship of Gerardo Machado (Browning). During his era, freedom of expression was enjoyed by journalists. Newspapers, publications and other dailies thrived in the city of Cuba, Havana. This period was also marked by prosperity because political parties sponsored lots of publications and added to the benefit of the country’s economy. However, the exercise of the freedom was shaken by the plan of Machado to assimilate and provide government subsidies in exchange for support in 1928 (Browning). The following years was marked by economic downturn and political unrest that further led to the end of freedom enjoyed by the Cuban journalists. The fourth period started after Machado was overthrown in 1930 until 1959 (Browning). For 29 years, Batista ruled the nation. During the reign of Batista, the freedom of expression was experiencing threat of extinction. Though, technological innovations in journalism were introduced in the country. Among these includes increased commercial sophistication and steam-powered printing presses (Browning). However, at the latter part of Batista’s reign, the freedom of expression has finally faded because the government took control of the press. The fifth period started when Batista was overthrown by the communist group led by Castro in 1959 and continues at the present era (Browning). Since the beginning of Castro era, the freedom of expression was already curtailed. Eventually, the press and media were finally controlled by the government and journalists were not given freedom to voice out their thoughts against the government. The government’s strict control over media started in 1930. No independent journalists were freed to release publications which have the effect of criticizing the government. During that period, journalists tried to oppose the move of the government but to no avail. Finally, in 1990’s through the introduction of Internet, independent journalists have found new medium to castigate the government’s control of information (Browning). However, the media, private and public, are still under the control of the government. Information dissemination is still suffering strict regulation. Independent journalists also continue to struggle and risk their lives for an independent journalism. It can be observed that since the evolution of media, the government already held control of it. The changes in phases under several governments have made media limited and restricted. Some of the actions that the government had done in curtailing free press and flow of information were censorship and closure of newspapers (Browning). Until now, the freedom of information remains evasive and independence of journalists is still obscure to be enjoyed. Current Status of Media in Cuba In Art. 53 of the 1976 Cuban constitution, freedom of press and expression have been explicitly stated. However, such freedom is subjected to limitations as contained in Art. 62 Art. 5, further, contains that all communication should be controlled by the Communist Party for the benefit of the country (Browning). As an effect, information was regulated and controlled by the government. Journalists were also restrained from publicizing without the knowledge of the state. Apart from that, journalists were arbitrarily imprisoned for exercising their freedom of expression. Mass media in Cuba is definitely not free. In the field of print media, the nation maintains three newspapers which are fully regulated by the government. These nation’s newspapers are Granma, Juventud Rebelde and Trabajadores (Browning). Granma is the official publication of the Communist Party which was founded in 1965 (Browning). Juventud Rebelde usually contains the same youth-oriented stories covered in Granma but in simplified and summarized manner. The Trabajadores, on the other hand, is more politically inclined publication as it contains Marxist principles (Browning). Notably, Granma’s circulation has widened in some other parts of the world through the power of internet. The website is called Digital Granma Internacional (Browning). It is also noteworthy that during the recognition of the press, the Union de Periodistas de Cuba (Union of Cuban Journalists) was founded in July 15, 1963 (Browning). It is a nongovernment organization which engages the membership of professional journalists in order to work in distinguished media in the country. However, such organization has already been controlled by the government and its constitution also dictates that editorial line of journalists must follow that of government. On this era of technological innovations, independent journalists found internet as a means of voicing out their cries and redress against the Cuban government. However, the control of the government in curtailing unwanted information has also reached the World Wide Web and several independent journalists have been imprisoned for such exercise of expression. It is noteworthy that 21 journalists have been recorded to have been imprisoned after a closed-door trial (â€Å"Attacks on the Press in 2008†). Among the journalists that suffered the harshness of the state is Yoani Sanchez, 33-year old blogger (â€Å"Attacks on the Press in 2008†). Sanchez, at first, found freedom through her blog called Generation Y which contained observations about hurricane devastation, politically motivated arrest, and food shortages (â€Å"Attacks on the Press in 2008†). Her blog has been read abroad but has also been made known by the government. Thereafter, her passport was confiscated and was not allowed to leave the country. Today, state authorities has started to regulate internet cafes to track down individuals with the purpose of publishing dissent against the government through internet. Another independent journalist that has experienced the government’s cruelty is Victor Rolando Arroyo (â€Å"Cuban Journalist in Second Week of Hunger Strike†). Arroyo, who writes in Union de Periodistas y Escritores de Cuba, was arrested during the fight for independence press in March 2003 (â€Å"Cuban Journalist in Second Week of Hunger Strike†). He caught the world’s attention when he took hunger strike for almost two weeks because of the maltreatment and indecent treatment of prisoners like him.

Comparative economic systems Essay Example | Topics and Well Written Essays - 2500 words

Comparative economic systems - Essay Example With industrialization came the need for a skilled and diverse workforce where traditional work arrangements were no longer feasible. During the Cold War period the world was divided into two main camps with the West (USA, W. Europe) embracing a free market economic system and the East (USSR, China) embracing a command economic system. In a free market economic system a nation’s economic activities are the result of individual decisions by buyers and sellers reflected in the price of products and services in the marketplace. People have the freedom to develop their talents and abilities and take up work or enter professions according to individual choice. They can also produce and supply goods and services as private businesses freely within legal and contractual obligations. The free market economic system of the West adumbrating free enterprise has been (and continues to be) referred to as capitalism. Up until the end of the Cold War, capitalism was a term of opprobrium to the East where communism ( a term of opprobrium to the West) was the term used for a command economy where all economic activity of the nation was controlled centrally by the government (mediated by the Communist Party). No private individuals were allowed to own and operate the means of production of goods and services. Public ownership, except in very small scale, local economic activity, was the norm. As everyone knows, USA exemplifies the paradigmatic capitalist state while Soviet Russia and China used to exemplify communism. Things have changed for Russia and China since the 1980s (although the latter still holds onto the communist label) and what these changes are, how they have been adopted and the progress achieved are the concern of this paper. A third kind of economic system called socialism is adopted by some countries with most of the major industries,

A specific function of an element of the U.S.Department of Homeland Research Paper

A specific function of an element of the U.S.Department of Homeland Security...I want to ICE - Research Paper Example However, it seems that many had barely looked at the surface, while credits for the many accomplishments in the preservation of national security were enjoyed by renowned groups only. There is more to ICE than meets the eye. Crime has many forms, and until one is committed, authorities may not be instigated to design the appropriate laws and the organization to enforce them. The establishment of the Immigration and Customs Enforcement (ICE) entails a long history of trial and error. From a small unit, it evolved into an all-encompassing crime-busting organization, and front-liner in the operation against terrorism. In fact, before 9/11, immigration and customs authorities were not widely recognized as an effective counterterrorism tool in the United States. ICE changed this by creating a host of new systems to better address national security threats and to detect potential terrorist activities in the United States. ICE targets the people, money, and materials that support terrorist criminal activity (Fay, 2007, p. 591) So much was the impact of the 9-11 tragedy that the Government addressed areas of â€Å"national security† before all other concerns. Intelligence planned to engage in strategies to monitor all means of communications and dissemination of information. The President made efforts to build close relationships with his counterparts abroad to extend the nation’s scope of alliance. Federal authorities created ICE to ensure that whatever the cause of the blunder was, it will not happen again. Today, although ICE is hardly ever portrayed in the big screen like the FBI and CIA, and thus is not identified by many, it is always included in the cast when national security is at risk. They perform such functions that affect millions of lives, directly and indirectly. Since then, the United States has not been subjected to anymore instance of terrorist attack, and the question lies on whether it was due to ICE’s effective performance, or

DISCUSS THE CONCEPT OF HEALTH PROMOTION AND ITS CONTRIBUTION TO Essay

DISCUSS THE CONCEPT OF HEALTH PROMOTION AND ITS CONTRIBUTION TO POSITIVE HEALTH - Essay Example In some cases, the drivers of such actions are individuals; whereas, in other cases, such as alcoholism and smoking, a collective mindset and use of force is necessary. Such cases may require use of coercion to enforce the corrective action. A significant aspect of health promotion is health education which aims at creating learning experiences for people by imparting knowledge related to the various elements of health and demonstrating what actions are needed to maintain good health (Green & Kreuter, 1999). Health education maybe an individual or a collective effort; it may result in direct benefit (to the person who is suffering from health problems) or indirect benefit/ positive externality (to people other than the person being educated) (Bandura, 1977). What distinguishes health education from secondary learning is that health education is a methodical, planned learning exercise which is proactively undertaken in order to make people aware of the various risks associated with he alth and their possible solutions (Ottoson & Green, 1987). The concept of health promotion; however, extends beyond that of health education in that the former attempts to facilitate the high quality of life outcomes proposed by health education . It provides the necessary organizational, political, social and economic mechanisms needed to achieve the objectives proposed by health education. In other words, one may infer that health education is a pre requisite to health promotion; without self-awareness regarding health-related issues health promotion is futile. Without health education, health promotion would be limited to a politically manipulated activity marked by death of the â€Å"social† aspect of health promotion needed to avoid the manipulation. Over the years, there has been a growing shift of responsibility associated with positive health outcomes from the government and environmental agencies to individuals (Bunton, 1993). Thus the balance has tilted from environ mental activists, medical agencies and public service institutions to individuals, schools, and households (Bunton, 1993). This has been made possible by the rapid influx and falling prices of technology, greater awareness through media as well as high levels of community support for such health promotion programs. Schools are not volunteering in educating students about healthy diet and issues such as obesity, AIDS, as well as preventing the use of drugs and alcohol (Tonin, 1980). Community organizations have sprung up in order to promote better standards of living for its members. Such action involves greater co ordination and communication across various sectors of the society (Thorogood, 1992). However, in order to achieve the intended outcomes and attain maximum efficiency, health promotion must be simultaneously achieved at both levels (the individual and collective) (Thorogood, 1992). Thus, all groups pursuing health promotion ought to decide their share of contribution to th e overall effort in the context of local culture and lifestyle (Thorogood, 1992). Victims of poor health are a vital component of this decision-making process and their views on which group should attain maximum responsibility ought to be taken into account (Green, 1986) (Flynn et al.,

The Benefits of the Universitys Agricultural Patents Article

The Benefits of the Universitys Agricultural Patents - Article Example The cell line defends stops the growth of mycotoxins. Within the global food environment, Mycotoxin-infected agricultural products precipitate economic losses (DAR, 2006). University of Illinois (2013) offers Agriculture-based courses for farm enthusiasts and entrepreneurs. With the ARS and-University of Illinois patent partnership, the outcome is the improvement of our nation’s agriculture product outputs. The partnership ensures there is abundantly safe top quality food on the American people’s tables. The service helps its citizens, communities, and entities generate economic gains from agriculture transactions. The service scientifically conducts research to solve the nation’s agricultural problems. Solving includes protecting the agricultural products from identified pests (DAR, 2006). The purpose of the patent is to improve the nations’ agricultural food product scene. The improvement includes reducing the economic loss from infected agricultural food products. The research finds ways to reduce or eliminate the harmful effects a certain aflatoxin strain. Aflatoxin reduces the agricultural food products’ quality (DAR, 2006). Further, the ARS partners with University of Illinois to create anti-toxin defenses. Certain fungi produce mycotoxins. The mycotoxins crop up and develop on certain plant types. The plant types include barley, corn, wheat. Aflatoxin is one type of mycotoxin, a toxin (having ill effects) substance (DAR, 2006). The patent has many future applications. The patent will ensure an increase in farm plant outputs. With the anti-toxin patent, the University of Illinois and the United States Governments Agricultural Research Service increases the supply of plant food. With more food, the U.S. Governments hunger statistics is reduced. More food supply contributes to the reduction of farm food prices.  

Effective Team and Performance Management Essay - 5

Effective Team and Performance Management - Essay Example 362). Therefore, an organization must always look for ways of bringing together all the departments to ensure that the specific goals and objectives are achieved. According to Furnham et al, (1993, p. 245-257), in an organization setting, the sources of conflict are varied. Many conflicts are related to psychological factors such as wrong attitudes towards accomplishing given tasks. Some members will normally not co-operate in various areas of an organization due to psychological factors that they pose. Some members may also have emotional problems which will be expressed at most times while the employees are working together. For example, some may show signs of ranging temper, some resentment while others become indifferent during moments of team work. They may not be able to bring forth their ideas with ease, hindering team work. There are also several behavioral practices that work contrary to team work (Kaplan & Miller 1987, p. 346-360). For example, some members may withdraw fro m the team, others choosing to choose the team members that they would want to work with. This will obviously hinder cooperation in the organization. Leadership plays a key role in the achievement of team work within the corporate world. A leader is any individual who is able to influence the employees towards a specific direction. Leadership may come from any level or department within an organizations setting (Kaplan & Miller 1987, p. 346-360). It is important that appropriate leadership is given, so that all the employees move towards the same direction. In this report, I reflect on various activities that have we have undertaken as a group, in the bid to learn more on the topic of team work. I use the tasks to understand how well team work can be accomplished within an organization. The outcomes of the teamwork within our group indicate the issues that surround cooperation and cohesion within the organizations. Reflection of various the tasks undertaken During our class work, we were called upon to take various tasks as groups. They would either be seminar activities or weekly activities. One of these activities included the egg flying contest. In this case, I and other team members were called upon to use all the resources that were available to ensure that an egg would not breaking after being dropped from a height of 2 meters. Several resources were availed to us, which included: six straws, one balloon, three elastic buds six cotton buds, and four papers; each one and a half centimeters. The task ahead was to be able to put our minds together and see how the materials available to us were of use. The team members had to use the resources ahead of them with a lot of care. The resources were limited, yet the given task had to be accomplished. There was need for the team to give way for a leader, one who everybody would listen to and who would give direction on how exactly to use the materials to accomplish the task ahead. In such a moment, most members f eared to fail, they wanted to be correct and perform the task to success. Therefore, a strong leader, one who would take into considerate the task ahead was needed. Our next exercise involved investigation of Cambridge crime. In this case, the team was supposed to investigate a crime scene that had happened in the nearby location. The accurate information in such a scenario was of great

Genius and Intellectual Mentality in America Essay

Genius and Intellectual Mentality in America - Essay Example The program The Big Bang Theory is a social experiment that is not only entertaining, but reveals a great deal about a sub-culture that has emerged that is child-like in their social habits, but have intellects that exceed the average. The Big Bang Theory revolves around four males and one female. The four males all work at the same university as research scientists and two of them live in an apartment as roommates. The third male lives with his mother and the fourth male lives in an apartment by himself. A more detailed character analysis will be within this essay, just as it will be important for clear definitions to be created for the words nerd and geek, which is the foundation of the identities of the four male characters. It is in the conflict between the social status of the men to the young woman that provides the opportunity for humor and social exploration. Definitions According to Anderegg, the definitions of a nerd or a geek are often interchangeable, but the specific def initions are actually quite different. A nerd is defined by someone who tends to be focused on academics and as a result is socially awkward. A geek is defined by someone who is more focused on sub-cultures that are not as socially accepted, but are still part of pop culture. Anderegg states that â€Å"nerds and geeks possess arcane knowledge that few other people possess† (n.p.). The types of knowledge that they have often mean extensions of popular culture products, which can mean computer and electronics. This also includes playing games such as World of Warcraft, collecting action figures, reading and becoming absorbed in alternative universes through books, comic books, and graphic novels, as well as being fans of cult favorite programs such as Star Trek, Stargate, and Battlestar Galactica. One of the reasons that nerds and geeks are attracted to alternative universes is that they are not completely comfortable in the social structures of the real world. In learning abou t and inserting themselves in the fantasies of new universes, the possibilities of being a welcomed member or an imagined hero allows for the social awkwardness to be minimized (Pustz 250). In learning about those who engage in online gaming, it is possible to see that the social problems of not having the appearance of a sexually attractive body falls away with the opportunity to build an avatar that allows the individual to express their identity in a safe space, where it is arguably easier to become the more authentic self. In creating and ‘living’ a life in a fantasy world, the social problems that have impeded them from expressing themselves is melted away and they can sink or swim according to who they are on the inside (Waggoner 10). Character Analyses The lead character who exhibits the most realistic characteristics and against whom the caricatures of the other three males are balanced is Leonard. Leonard is played by Johnny Galecki who previously was on the Am erican program Rosanne, which also was a reflection of contemporary culture (IMDB). He has a realistic appearance which is not overly good looking, nor unattractive. Through the prop of a pair of glasses that dangle near the end of his nose, only to be repeatedly pushed up again, he is transformed

The Company Yahoo Essay Example | Topics and Well Written Essays - 750 words

The Company Yahoo - Essay Example As the discussion stresses, the company was on the height of its success at the time of dot-com boom in 2000 when its stock price plunged to record high. Yahoo! also started its free mail service in response to the release of Google’s Gmail in 2004. In the following year, the company took over Flickr, a thriving photo sharing service. Yahoo! continued to expand by acquiring and purchasing innovative business in need of capital. The range of services offered by Yahoo! also rose in the year 2005 when the company stepped into Web 2.0 services. MSN Messenger and Yahoo! Messenger became interoperable in 2005 which was another great achievement for the company. Yahoo! also allowed its mail users unlimited free space in 2007 as it removed the barrier of 1GB storage. In 2008, in the time of recession, the company announced the layoff of 1000 employees. The company was facing difficulties in competing with the efficient Google. The main revenue model for the company was advertising ini tially. Afterwards, the company started making money from the augmented services that it offered. Efficient management of capital and reduction in expenditure helped the company to gain its profitability in the pure internet business. In 2008, the company was approached by Microsoft for the offer of a merger. However, Yahoo! rejected the offer of Microsoft as the share price being offered was very low. Recently, Yahoo! webpage is seen to be changed and a new version is launched called the Metro. This new look also has links to famous applications such as Facebook.com and Netflix. E-commerce website like Yahoo! needs to constantly innovate and develop new features on the website to attract more users and subscribers. The company right now faces lack of originality as it is engaged in merging and acquiring already established businesses like Flickr. The customer data which is private should not be used by the company to be sold to marketing agencies.

Saving Private Ryan Movie Review Example | Topics and Well Written Essays - 1000 words

Saving Private Ryan - Movie Review Example A subjective point of view usually shows the viewer what the main character is experiencing in the story. To create this point of view, Spielberg had to show us shots of Captain Miller looking at something and then shows us how the captain reacts to what the captain witnesses. This subjective point of view, not only appears during the first epic battle scene but also in other battle scenes throughout the film. There is another remarkable battle scene later in the film where the soldiers encounter German troops in the bombed-out remains of a French town. Spielberg is keen to show the viewer that men who fight in the war put their life on the line for others, not for heroism, but because it is their duty to do so. He clarifies this point by using Captain Miller’s point of view. Miller is a delightful, soft-spoken individual that experiences the horrifying violence of the battle scene as he sees other soldiers lose their lives. As the leader of his group, Captain Miller lets us i n on the importance of winning the war and at the same time shows the viewer on his determination to complete his mission of saving Ryan’s life so that he can go back home. Question 2 One controlling motif in the film is the use of noise and silence. This motif is clearly brought out especially since Spielberg uses Captain Miller’s point of view. ... This happens during the first battle scene on the beach where a soldier tries to ask him for orders, and he snaps out of the silence back to the noise. The elimination of sound is an effective expression of Captain Miller’s state of mind at that time. It could be logically significant because his hearing could have been damaged by the blasting noise of the battle machines, or a psychological trauma of his emotional pain. This motif helps to enhance the subjectivity of the film as well as the theme of courage. In a way, a soldier has to face his opponents and to Miller blocking out all the noise so as to see things clearly helps him to be courageous to face the battle. By alternating between the noise and silence during battle, Spielberg shows his mastery of sound editing while he lets the viewer experience what the soldiers are going through on the battlefield. It is doubtless to say the Spielberg expertly uses this motif to enhance the theme of the film as well as carry the v iewer through the battle experience. Question 3 Spielberg uses Tom Hanks as Captain Miller and in doing so succeeds in portraying him as a human. He conveys his humanity through his ability to lead his group of men in their quest to save the life of one man. In doing so, they need to stay alive amid exploding bombs and flying bullets. Captain Miller knows that it is necessary to win the war but what drives him is the desire to survive it all and go home to his wife and family. This desire drives him to complete his mission because he knows that family is an extremely fundamental aspect of one’s life.

Of Mice and men Essay Memories? Yeah, Ive had plenty, seen men come an go on this ranch, so many I cant hardly remember them, but two stick in my mind like it was only yesterday, but must be near on twenty years ago oh Im Slim, I lead the mule team, sure does beat busting a gut bucking barley now where was I? Yeah, thats right these two guys Came in one Friday, Boss was sure mad cos they were late. Youve never seen such an odd pair George, he was small, neat, quick witted but Lennie, my was he huge! Funny thing was his name was Small! He was like a great bear and he wasnt too clever either. Funny how he and George strung along together. Anyway, they come in Friday, Boss had been given us hell all mornin! I was out on the fields when they came out. Candy was with them and seemed to be showing them around the barn. Lennie seemed excited bout somethin. George came over and introduced them, Hi, Im George and this big fella here is Lennie. Lennie then tried whispered something to George but I heard every word, George, George, ask him bout dem dogs, please George? George looked a bit embarrassed. Candy tells us you got some new born pups. If theres one goin spare, you reckon Lennie could have it? George asked. Yeah sure you can Lennie, I said Come by the barn later and you can pick one out. He went all shy, with a smile from ear to ear, almost like a little kid. Lennie came down to the barn after he had finshed buckin, he sure was on hell of a worker, and he picked out his Pup. I tried to explain that he shouldnt be taken out of the box , but the big bastard didnt take no notice of it, ha, gawd he must have been the stupidest guy I have ever met. Now where was I oh right, so Lennie had got his Pup an it must have been dusk so we all headed back to the bunkhouse, and little did we know how much was gonna happen that night. We sorry my throats a lil dry, could ya pour us a drink? Cheers. Ah, thats better. Anyway, me and George were headed back to the bunkhouse and I started talkin to George bout Lennie, He sure is some worker, aint he? I mean when you said he were a good worker, I thought you meant he just didnt complain, but by golly, he must have beat every bucker on the ranch, with one hand! George chuckled. If only he wasnt so stupid I could be livin a dream. He said and looked in to the stars. So, how come you travel with him, I mean I aint never seen no-one that looks out for anyone as much as you look out for him. He looked a lil taken back by that but he simply answered, I promised his aunt I would look after him, an by god Ive had too. But he will do anything I tell him too, George started to smile, I once told him too jump in a river, and I knew he couldnt swim but he still did it and nearly drowned cos o me. Ever since then I havent done anything to him that might hurt him. He stared into the ground, almost as if he regretted doin that to him. I broke the silence, So, how come youve ended up here? I asked. He didnt want to tell me, I could tell by his face, but I think he new that he could trust me. You wont tell no-one, will ya? He asked Course I wont I replied Well He started off, We were working in weed, and Lennie was settin under some trees havin a break cos we had finished our morning load in an hour and a half. He smiled with a great sense of pride, Then one of the bosss daughters came over and started talkin to him, and the stupid bastard ended up touchin her dress and the dumbass didnt let go. The daughter ended up shoutin Rape, rape! everyone looked over and saw a girl strugglin with a guys hands all over her. I literally had to smack the big guy to get him off her. We then had to run for a lives. We ended up squatin in a river in some reeds. They went straight past us an never saw us, but there still after us. Luckily I think thats about 100 miles away, thank god. He sighed with relief. Lennie then brought this puppy into the bunkhouse, George, George look at da puppy, Slim gave it to me. George turned aroun and went psycho at him, Lennie, you dumb bastard! You gotta leave the pup in the box with its mum other wise your gonna kill im! Do you wanna kill him? Do ya? Lennie cowered away into the corner. Of course not George. Ill put him back straight away now, He ran out, an nearly hit his head on the top door, ha. Candy then cam in the bunkhouse. He was an old guy, busted his arm and had to stay there, or so he said. He came in with his dog, which wouldnt be so bad, but the old thing stank. Carlson, one of the buckers, offered Candy an option, You should shoot that old dog, Candy. I mean hes no good to any of us. Candy looked at his dog, I couldnt shoot him, Candy said, Ive had him since he was a pup Why dont I shoot him then? Carlson asked, Ye, Ill take him out to the forest and jus shoot him in the back of his head. He wont feel a thing, I swear. Your probably puttin him through more torture keepin him alive than shootin him. A tear was wellin up in Candy. This pup was his only friend. Candy relented and Carlson took the dog and you then heard a shot in the distance. We all looked at Candy, he was starin at the wall. I offered him a new puppy but he didnt answer. Crooks, the niggah entered and told me tha Lennie was messin with the pups. George looked at me and told me to kick him out if hes causin trouble. I went off and made sure he werent doin nothin stupid. Well stupid even for him. I was in the stables, makin sure all the pups were alrigh after Lennie had been messin with em, when Curley came stormin in, shoutin something bout his wife. I didnt want notin to do with it so I went to the bunkhouse but he kept on about how his wife is always sneakin off without his permission, and how he suspected me of havin an affair with his bitch. Ha, if I ever had an affair, it would be with Marilyn Monroe rather than that tart. I went into the bunkhouse and he still wouldnt let it drop so I said to him, Curley, I would never even think about touchin your bitch, cos I dont like that type of tart. All then men a fallin bout laughin and joined in with havin a lil dig at Curley. Sadly though, Lennie was smiling about something, he was in his own lil world, but Curley saw him an thought he was laughin at him. What are you laughin bout you yellow bellied bastard? Curley was squarein up to him and Lennie didnt know what to do. You bastard! Curley smashed the poor fella round the face and knocked him over. Lennie just stood up and did nothing bout it. He looked at George and was screamin at him to make Curley stop. I knew George didnt want no trouble so he kept quiet, but Curley was smashin Lennies head in. Then suddenly George screamed, Get im Lennie! Get im! Then Lennie switched, he grabbed Curleys hand and just squeezed, looked as if he was killin the bastard. George was smackin im tellin im to let go but he wouldnt budge. Lennie had im about 2 ft off the ground. We had to pull the big fella off of Curley. I went over to see Curleys hand and Lennie had jus disintegrated the bone, twas jus skin, not a bone in it. I knew that George and Lennie would get their asss busted for this so I thought Id have a heart to heart wit Curley, I said, If this gets out, Lennies gonna get canned for it. But your reputation as a tough guy will be ruined as well. Now if you say your hand was caught in a machine, then we will say that too, but if you dont, we will ruin your reputation til nobodys gonna be scared o you, you got that? He nodded his head, whilst screamin, and I told the guys to take him to doctors fast. That, thank God, was the end of that night. The next day, notin too much happened. We went into town and Candy, Crooks and Lennie stayed at the ranch. Thankfully that was all that happen that day. Next day was the horseshoe tournament. I never used to be that good at them, but they sure were good fun. Crooks did tell me that Lennie was looking at his pup, but not doin anthin to harm em. We had jus finished the tournament and George went to get som water. He came back, but didnt look to good. I was jus gonna ask him if hes alrigh but then Candy came out of the stables waving his arms bout screamin that somthin had happened to Curleys wife. We all went to see what was wrong, and it werent a pretty site. She was layin on the hay, at first ya thought she were sleepin, but then ya noticed her neck was bent in a bad way. Curley didnt look much sad, more angry then shouted, Im gonna kill the son o a bitch! Everyone started to get agitated and some people started shoutin, Lets get im, and Ill go get ma gun! George had gone real pale and Curley said to im, Your gonna stick wit me, so I don think you were involved, alrigh? George nodded. Curley told Crooks to get all the horses ready, seemed like it were a search party. Well it was but not the usual search party, it was more o a search an kill sorta party. Me, Curley, Carlson and George headed south whilst the others headed west, jus in case. I knew George knew where Lennie was, an we strayed away from Curley and co.. We ended up near this river and George said hell go in alone. I stood by some trees an saw everythin that happened. George went up to Lennie, pulled out Carlsons luger and told Lennie to look out toward the horizon. Lennie was smiling talkin to himself I think, George looked hesitant but found som courage and pulled the trigger. Lennie fell down the bank, and jus lay there. George walked over and didnt look to good. Curley and Carlson came over, makin up som story to tell the others. But I knew that George didnt wanna have to shoot Lennie, so I went and had a chat wit him. I simply said, It had to be done. He looked at me, and seemed glad that someone had said that to him, but still looked troubled. We got back to the ranch an everyone wanted to know what happened. Carlson was leading the story, and half of werent even real. The next couple o days was hard on George. He seemed to be in a completely different world, starin into space. He did get over it though, took him a couple o weeks, and he turned back to the ol George. God, that weekend was the longest weekend I have ever had.

The Investigation Of Police Corruption

The Investigation Of Police Corruption One cannot separate police corruption from police abuse of force. Whenever an officer uses force, that officer needs to be able to justify the use of force. Law enforcement ethics go far beyond an officer choice to accept a cup of coffee, or a free car wash. The fact remains that whenever an officer lowers the ethical, and morals standards it affects every area of police operations and adversely affects the ability of law enforcement agencies to perform the mission that the community has entrusted them to do. When police misuse their power, and authority it lowers the departments professional competence; and at worse it spreads corruption through the department. Tract: The job of a law enforcement officer can be tough. Law enforcement officer are sometimes plagued with situation that test their ability to enforce the law and maintain order. Law enforcement officers today face a constant battle to establish and maintain higher ethical standards for police personnel. This mission becomes tougher each day when one considers the importance of fighting terrorism, drugs, human trafficking, and many other major issues. In the last few years, ethical issues in law enforcement have been affected by three critical factors-the growing level of temptation stemming from the illicit drug trade, the challenges posed by decentralization, and the potentially compromising nature of the police organizational culture. These factors make managing for ethics today far more different and demanding than it was in the past. How can law enforcement fight the war on crime and maintain personal liberties? One can examine the social stigmas and stereotypes that either further or reduce police corruption to help develop a better understanding of police corruption. Finally what is the solution to effectively control police corruption, enforce proper ethics, and ensure law and order? Terrorism is a new issue for law enforcement personnel today. Terrorism has had a great impact on the police mission here in the United States. Experts now are debating the proper way to address terrorism in America without creating ethical dilemmas. Can federal law enforcement hold all suspected terrorist within the United States in jail until they are cleared? Not legally. Would it be ethically okay to arrested terrorist, and allow them to be tried within the United States without legal counsel? No. Can the federal Government issue wire tapes on citizens phones without creditable evidence. No. What is the correct way to handle the issues on terrorism? The Police Executive Research Forum has outlined key ways to handle the war on terrorism. First, in order to prevent terrorist acts on U.S. soil the public must understand that Federal Law enforcement cannot do it alone. State, and Local law enforcement along with the general public must work together to gather intelligence on suspect ed terrorist. Local Law enforcement can use the community policing method to establish citizen engagement, partnership, trust, information sharing, and collaborative problem solving. With a relationship developed with the community, police can better identify potential suspects, and become proactive in the war on terrorism. Law enforcement can ethically address the war on terrorism. The problem is that social stigmas can play a key role in either furthering police corruption or reducing it. Social stigmas impact the way police perform because police sometimes use social stigmas to be proactive rather than being reactive to crime. For example, an officer may approach a young man walking around a suburban community with his hat turned to one side, and his pants below his knees. The office may see the social stigma of a thug, someone who is considered to be up to no good. When police use social stigmas in this way, the community will view it as good police work. However the use of social stigmas can also bring on police corruption. Some officer may violate human rights, with racial profiling, or just mistreating someone because of their outer characteristic. For example, whenever an officer sees someone with big rims and loud music he assumes they sell drugs. So the officer pulls the young man over and treats him like he is a criminal. First the officer ask for identification, then removes the young man from the car and performs an illegal search of the car and finds drugs . Now the officer will be forced to falsify reports, which is a form of police corruption. Social stigmas are no better than stereotypes; one person may fit the stereotype or social stigma, but one should never conclude that a stereotype or social stigma applies to everyone. When officer begin to apply a social stigma to everyone, they can easily fall into police corruption. With that being said, citizens should not apply social stigmas to all police officer. One can conclude that some police officers are involved in police corruption but not all. The ethical issues seen in police corruption can also be seen in police abuse of force. One cannot separate police corruption from police abuse of force. Whenever an officer uses force, that officer needs to be able to justify the use of force. Law enforcement ethics go far beyond an officer choice to accept a cup of coffee, or a free car wash. The fact remains that whenever an officer lowers the ethical, and morals standards it affects every area of police operations and adversely affects the ability of law enforcement agencies to perform the mission that the community has entrusted them to do. When police misuse their power, and authority it lowers the departments professional competence; and at worse it spreads corruption through the department. Although only a few officers may be involved in an act or corruption or abuse of force; the community will perceive all members of that department as incompetent, corrupt, or brutal. It is important to know that a few incidents of corrupt or brutal police behavior can overshadow or even negate years of efficient and honest po lice service, and cause long-term damage to an agencys reputation. Illegal and unethical acts by police officers, create community increased antagonism toward what appears to be an unappreciative or even hostile public, less citizen cooperation, more friction in police-citizen interactions, more invitations to corruption, and more confrontations that may lead to the use of excessive force. It is a classic vicious cycle, with worsening community relations, an increase in hostility between police and citizenry, and a concomitant growth of public contempt for the police all generating a downward spiral that far too often ends in tragedy. Many ethical factors that are behind police corruption can be found in police abuse of powers, and excessive force. Police corruption is sometimes motivated by an officers desires for money, respect, and power. Likewise, the use of excessive force can be used to ensure and officer receives money, maintains power, and respect from the community. Many officers who are involved in corrupt activities will often use force to maintain and protect their corrupt activities from reaching the public or media. In addition to that, officers who are under a lot of stress can fall into corruption, and are more likely to use excessive force. When police use excessive force, or fall into police corruptions it only hinders the overall mission or law enforcement. The only way to prevent corruption and police abuse is to train officer in ethical standards to strengthen the foundation of police ethics. To strengthen ethical standards officers need to be trained in the correct ways to change moral standards of contemporary society. The world today has lowered the moral and ethical standards of citizens, and police alike. The lack of moral standards, has allowed the community, and law enforcement to take justice in their own hands. Secondly, police need to know and respect the organizational expectations of the police. Society has certain perceptions, images, and expectations of the police. Some of the expectations that the community have of police may not be accurate or realistic. Misinformed or conflicting perceptions of the proper role of the police and conflicting expectations about what is or should be expected from the police often contribute to an environment of confusing built on mixed or even conflicting goals and objectives. As a result , the working environment of police, their morals, and their susceptibility to corruption and brutality are closely watched by the public and the media. With this in mind, police can better handle situation that propose ethical dilemmas. For example, officer now know that the community expects police to be corrupt, and to abuse their powers, so if a officer does the complete opposite, he or she can help raise the standard, and avoid some of those ethical factors that are behind police corruption, and police abuse of powers, and excessive force . Formal training programs can help to ensure that officers understand their departments code of ethics and related expectations Elevate the importance of ethics throughout an agency Underscore top managements support, and Provide specific assistance in areas directly related to ethical behavior (e.g., stress management, use of force, violence reduction, and behavioral science classes). Although more study is need- ed in this area, some empirical evidence supports the contention that formal ethics training fosters improved ethical behavior. One recent study found that officers specifically trained in anger management had fewer incidents of excessive force in making arrests. A distinct but related topic is whether higher education promotes ethical behavior. Clearly, advanced formal education enhances the maturity and professionalism of police officers. The question is whether those positive attributes spill over into the ethical arena.Some research suggests a positive relationship. Adva nced formal education appears to reinforce previously established ethical values in individuals. At the organizational level, one study identified a commitment to learning as one of the three most prominent characteristics common to highly ethical organizations. In conclusion, police corruption anywhere, hurts police everywhere. Police are held to a higher standard by the citizens, and the media. Police officers need to be aware of the social stigmas working against them. Law enforcement Officer need to be trained, and educated on how to hand ethical situation. If the law enforcement community seeks to change the image of police in American they must first become aware the ethical problems and avoid them. Secondly, Police with the help of education one maybe able to avoid the use of excessive force, and corruption. Lastly, law enforcement must correct, their attitude toward those who may fit a certain social stigma. Resource Page

Definition and purpose of computer accounting information system

Definition and purpose of computer accounting information system This literature review will begins with definitions and the purpose of (AIS) and discussion of the studies of general IT adoption and then reviews studies specifically focused on accounting software adoption. Then it will discuss the Uses,development and the step of AIS. The end of this literature review will discuss the effectiveness of accounting information system. Definition of computer accounting information system (AIS): The computer accounting information system (AIS) was invented by professor Karen Osterheld, It was used as a system of records for business keeps to maintain its accounting system. This includes the purchase, sales, and other financial processes of the business. [1]The purpose of AIS is to accumulate data and provide decision makers (investors, creditors, and managers) with information to make decision, while this was previously a paper-based process, most modern businesses now use accounting software such as UBS, MYOB etc. [1] IT Adoption Factors for computerized accounting: [2] Several studies (Thong 1999; Harrison, Mykytyn and Riemenschneider 1997; Cragg and King 1993; Moore and Benbasat 1991; Treadgold 1990) of IT adoption have identified a variety of motivating factors. Thong (1999) attempted to consolidate the myriad of IT adoption research by developing an integrated model of information systems adoption. This model is a useful framework in reviewing the variables that impact on business owners decision to adopt IT. Thong categorized the variables into four elements: 1. characteristics of the organizational decision makers: 2. characteristics of the technological innovation; 3. characteristics of the organization; and 4. characteristics of the environment in which the organization operates. According to the literature all of the above characteristics influence, to varying degrees, the owner- managers decision to implement IT. Characteristics of the Organizational Decision Makers In large businesses teams are typically involved in the IT decision-making process. This is in contrast to small business where the owner-manager is usually the IT decision maker (Thong 1999). In small business, therefore, the characteristics of the owner-manager are critical in determining the organisations attitude to IT (Rizzoni 1991). The particular owner-manager characteristics important to IT adoption are: innovativeness, computer self-efficacy, level of IT knowledge, education, and IT training experience (Thong 1999). Compeau and Higgins (1995) defined computer self-efficacy as a judgement of ones capability to use a computer. Small businesses that have CEOs (typically the owner) that have undertaken computer training and possess computer self-efficacy are more likely to implement IT (Delone 1988, Raymond 1988). Conversely, owner-managers can inhibit any worthwhile IT achievements through hostility or detachment toward IT (Thatcher and Perrewe 2002). Characteristics of the Technological Innovation The characteristics of the technological innovation itself are also an important determinant in the decision to adopt IT. Applying Rogers (1983) theory to the adoption of accounting software as the innovation, the software must be perceived better than the predecessor system (most likely a manual accounting system); must be consistent with the needs of the adopter, such as capable of handling GST; must be easy to learn and use; the results must be apparent; and the accounting software should be available on a trial basis. Over the past decade, the advent of powerful, low cost micro-computers coupled with user-friendly accounting software, have improved and lifted the barriers to IT innovation adoption. This has led to an increase in the adoption of IT by small business (Thong 1999). Characteristics of the Organization The characteristics of the organization are other variables that influences the decision whether to adopt IT. Organizational characteristics such as: business size, employees level of IT knowledge, industry sector, business location, and information-intensity has been analysed in previous research studies (See for examples: Fink 1999; Burgess 1998; Wenzler 1996; Attewell 1992; Yap 1990; and Delone 1988). Generally, the larger the number of employees, the greater the sales turnover, the more information-intensive the industry the more likely a small business will adopt IT innovation. Moreover, businesses tend to suffer resource poverty (Thong 1999) in terms of financial capacity, available time and IT skilled staff to facilitate innovation adoption. Characteristics of the Environment The characteristics of the environment in which the organisation operates relates to variables such as competition and external agents. For example, Link and Bozeman (2001) established that competition leads to innovative technology adoption. Treadgolds (1990) study indicated that small businesses with high IT adoption rates had been influenced by external agents such as: trade associations, wholesalers, voluntary groups and franchisors. Wenzler (1996) found that small business customers were a significant reason for implementing IT, more so than the influence of competitors. This paper extended the external agent influence to the role of accountants in the decision to adopt accounting software. Many small businesses are impeded by resource poverty, consequently the owner-manager does not have the available time or funds to source, analyze, review and implement software applications. Public Practice Accountants are in a unique position to provide systems analysis, design, implementation and support advice to their clients, thereby spreading the cost of acquiring this expertise among multiple customers. The accountant, therefore, could generally provide this service more efficiently and effectively, than if the small business owner performed the function himself or herself. Furthermore, at the time of this study, the introduction of the Goods and Services Tax (GST) was an external influence on small business owner-managers decisions to adopt a CAS (see for example Lief 2000). Motivating factors for the adoption of Accounting software [2] The advent of powerful, low cost microcomputers, together with user-friendly accounting software, has allowed a greater number of business to implement IT in recent years (Raymond and Bergeron 1992). The need to facilitate financial management is another motivating factor for adopting accounting software (McMahon and Holmes 1991; Gorton 1999). Moreover, some researchers have identified a link between the use of CAS and enhanced business performance (see Gorton 1999; Smith 1999; and Reid and Smith 2002). An alternative view is that a growing SME faces increased financial challenges and consequently there is a greater need for careful attention to financial management and financial reporting (McMahon 2001). The major benefits of implementing a CAS are to increase business efficiency and to facilitate timely information (Burgess 1997). The impediments to implementing a CAS are lack of time (Proudlock et al. 1999), owner-managers view that the CAS is costly (Head 2000), perception that the technology is not suited to the nature of the business (ABS 2000), and lack of IT expertise (ABS 2000; Burgess 1997). Accounting information systems Technology: [3] Input The input devices that needed win Accounting information systems include: standard personal computers or workstations running applications; scanning devices for standardized data entry; electronic communication devices for electronic data interchange (EDI) and e-commerce. Process Basic processing is achieved through computer systems in the personal computers to large-scale enterprise servers. However, processing model is still the double-entry accounting system . Output Output devices used include computer displays, impact and nonimpact printers, electronic communication devices for EDI and e-commerce. The output can be financial reports from budgets and tax reports to multinational financial statements. Uses of AIS [3] AISs cover all business functions from backbone accounting transaction processing systems to sophisticated financial management planning and processing systems. Financial reporting starts by capture important business transactions such as normal production, purchasing, and selling activities then these transactions are classified and summarized for internal decision making and for external financial reporting. Cost accounting systems are used in manufacturing and service company. This accounting system will help these organizations to track (measure) the costs for the production of goods and/or performance of services. In addition,it can provide advanced analyses tracking the cost of product or service. Management accounting systems are used for planning, monitoring, and control for a variety of activities . This allows managerial-level employees to have access to advanced reporting and statistical analysis. The systems can be used to gather information, to develop various scenarios, and to choose an optimal answer among alternative scenarios Development [3] The development of AIS includes five basic phases the time period associated with each of these phases can be as short as a few weeks or as long as several years. This five phases include: Phase 1 planning : In this phase the entails determination of the scope and objectives of the project, the definition of project responsibilities, control requirements, project phases, project budgets, and project deliverables. Phase 2 analysis :This phase is used to both determine and document the accounting and business processes used by the organization. It include three type of analysis which are: Data analysis is a thorough review of the accounting information that is currently being collected by an organization. Current data are then compared to the data that the organization should be using for managerial purposes. Decision analysis is a thorough review of the decisions a manager is responsible for making. Then models are created to support the manager in gathering financial and related information to develop and design alternatives, and to make actionable choices. Process analysis is a thorough review of the organizations business processes. These processes can then be modified or reengineered to improve the organizations operations in terms of lowering cost, improving service, improving quality, or improving management information. Phase 3: design: The design phase takes the conceptual results of the analysis phase then develops and involves the detailed design of all inputs, processing, storage, and outputs of the proposed accounting system. Inputs may be defined using screen layout tools and application generators. Processing can be shown through the use of flowcharts or business process maps that define the system logic, operations, and work flow. Logical data storage designs are identified by modeling the relationships among the organizations resources, events, and agents through diagrams. Output designs are documented through the use of a variety of reporting tools such as report writers, data extraction tools, query tools, and on-line analytical processing tools. Phase 4 Implementation:The implementation phase consists of two primary parts: construction and delivery. Construction includes the selection of hardware, software and vendors for the implementation;building and testing the network communication systems; building and testing the databases; writing and testing the new program modifications; and installing and testing the total system from a technical standpoint. Delivery is the process of conducting final system and user acceptance testing; preparing the conversion plan; installing the production database; training the users; and converting all operations to the new system. Phase 5 support: This phase has two objectives. The first is to update and maintain the AIS. This includes fixing problems and updating the system for business and environmental changes. For example, changes in generally accepted accounting principles (GAAP) or tax laws might necessitate changes to conversion or reference tables used for financial reporting. The second objective of support is to continue development by continuously improving the business through adjustments to the AIS caused by business and environmental changes. These changes might result in future problems, new opportunities, or management or governmental directives requiring additional system modifications. The Accounting information systems is very useful for companies and businesses in order to make the accounting process easier by spacial computer program or other system . Accounting software, make it easier to accumulate financial data for use in taxes, payroll, and other bookkeeping requirements. The step of the accounting system: [4] Step1: Recording ( recording expenses and profits that are very important to keep on file). Step2: Information processed for use (when processed, it is filed in the areas where it is most important). Sep3: Communication phase (common communications of this data will be used for payroll and tax purposes). In the first step all the data recorded in the accounting system in daily basis or minute by minute as sales, profits, expenses, and many other items will be used for future use in financial reports. Much of this data has to be kept on file for a number of years for example tax purpose. The next step that is taken is processing. In this stage most accounting software or programs, have different files and categories where records can be stored this filing or storage can be done manually by the individual or group of people who work on it and can also be set to do this automatically as information is entered into the system. Certain criteria can be set up in the program to allow the program to place files and data in the places or areas where it is supposed to go. The final step is the process of communicating the data in the area in which it should be communicated. First, and most importantly, tax records that are recorded and processed can be communicated at the time that filing taxes is done. Most corporations communicate there financial information on quarterly basis, other companies especially smaller businesses on an annual basis. In large corporations, like major retailers, there are often several smaller stores or branches of the company that must share information through accounting software or systems This information can help the company forecast sales, profits, loss, and a variety of other things. Many corporations share this information on a daily, weekly, or quarterly basis. The process of communication is probably the most important stage of accounting information systems because this is the point where results are known and records will be put to use. Most of the businesses and corporations now use the accounting system and become big part of them. Using resources available through accounting information systems allows major corporations and small businesses to record transactions and other financial information for use in the future. Moreover that the use of the accounting system by this company can make: the process much smoother, save money for the business, and save a great deal of time. easy to file and send documents to the IRS or other interested individuals. no need to take paperwork or other materials to an accountant for tax and payroll purposes. Taking advantage of this type of system can provide many great benefits to a large or small business. Accounting is a very important part of running and maintaining a business and the success of a company will often heavily rely on the practices and procedures that are used in the bookkeeping efforts of the company. The effectiveness of the computerized accounting [5] (Markus- 1983) shown that successful implementation of accounting systems requires a fit between three factors [17]. A fit must be achieved with dominant view in the organization or perception of the situation. Second, the accounting system must fit when problems are normally solved, i.e. the technology of the organization. Finally, the accounting system must fit with the culture, i.e. Systems will be useful when information provided by them is used effectively in decision-making process by users. (Otley-1980)[20] argues that Accounting Systems are important parts of the fabric of organizational life and need to be evaluated in their wider managerial, organizational and environmental context. Therefore, the effectiveness of accounting information systems not only depends on the purposes of such systems but also depends on contingency factors of each organization. (Ives-1983)Accounting information systems are said to be effective when the information provided by them serves widely the requirements of the system users. Effective systems should systematically provide information which has potential effects on decision-making process [12]. Accounting information usually is categorized under two groups: information that influences decision-making and mainly used for the purpose controlling the organization and information that facilitates decision (Huber-1990) [11] argues that, integration of accounting information systems leads to coordination in organization which, in turn, increases the quality of the decisions. (Cameron-1986 / Delone-1992) show that the effectiveness of accounting information systems depend upon the quality of the output of the information system that can satisfy the users needs [3,8]. Generally, accounting information systems; 1) provide financial reports on a daily and weekly basis and; 2) provide useful information for monitoring decision-making process and performance of the organization. (Simon-1987) [22] in his study used the first part of the above statement as measure of control for management and the second part for evaluating the effectiveness of the accounting information systems via continuous monitoring. Accounting information system is a computer-based system that (Nicoloau-2000) [19] defines as a system that increases the control and enhances the corporation inside the organization. Management is engaged with different types of activities which require good quality and reliable information. They also need non-financial information such as production statistics, quality of production and so on. However,( Essex and Magal -1998 ) said that quality of information generated from AIS is very important for management [10]. (Kim-1989) [13] argues that usage of AIS depends on the perception of the quality of information by the users. Generally the quality of information depends on reliability, form of reporting, timeliness and relevance to the decisions. (Doll and Torkzadeh-1988) [9] for studying the satisfaction of users use some concepts to measure the effectiveness of the accounting information systems. These concepts are information content, accuracy, format, ease of use and timeliness.
