buy custom Computer usage is a Threat to Human Health essay Most organizations all over the globe are embracing technology to ensure that the quality of their output improves. Computer usage is picking up at a higher rate in most of these organizations. The continuous usage of computers in most organizations is in turn posing a great threat to human health. For instance, it leads to back problems, eyesight problems, and leads to E-thrombosis. Opponents claim that computers are not harmful to human health as they promote speed and ensure accuracy of transactions in the organization. They see computer usage in organizations to be composed of only positive results. This paper explicates continued computer usage and the resulting health hazards. Computer usage leads to back problems. Computer usage involves a lot of bending of the back when typing the information into the computer. This could result in back pains in the end. This is especially rampant where the users sit on chairs that do not offer enough comfort. In most organizations, an individual is expected to work using the machine the whole day. This means these individuals spend the whole day bending thus straining their backs. This is a common occurrence in the busiest departments where computers are used to achieve faster and efficient processing of orders (Oja and Parsons, 104). Individuals are thus exposed to back problems that result in immense pain and could make individuals unable to work efficiently in the future. This dangerous health problem could result in a slower generation because these individuals are not able to carry out their normal activities. The back problems are becoming an increasing problem among the youth. The back problems are thus a serious threat to the countrys future. It leads to eyesight problems. Individuals stare at the computer screens every day they are on duty. Continuous staring at the computers while working could result in eyesight problems. This is because individuals are exposed to the computers bright light. They also have to strain especially when reading vital information from the computers. This continued exposure to the computer light leads to untreatable eyesight problems. The eyes could ache, and the individual could eventually lose effective eyesight (Shelly, Cashman and Gunter, 497). The unregulated computer light is dangerous and continued exposure to it leads to the indivdual even totally losing out the eyesight. Doctors have raised alarm that the eyesight problems resulting from computer usage are increasing at a faster rate. They also fear that these problems are becoming harder to tackle. The eyesight problems lead to loss of quality labor. This problem is prevalent among the whole generation; children and the youth could be affected posing a serious threat to the countrys hope. The loss of eyesight due to computer usage is could be avoided by regulating the number of hours one spends in front of the computer. Computer usage for longer periods could lead to E-thrombosis. This condition is associated with spending too many hours sitting in front of the computer. E-thrombosis leads to the swelling of the blood veins in the legs. Individuals who spend longer hours attending to computer activities without standing to exercise their legs risk suffering from this condition. In addition, the individual could be exposed to other conditions such as frequent collapsing and the inability to lead a normal life. Research asserts that individuals who spend longer hours at the computers without taking a break to exercise their legs risk the effect of blood clots in their veins thus the inability to walk later on. This means the flow in the veins is restricted, and the individual could lose his life. The unstable blood flow could lead to the eventual death of the individual due to the inefficiency of the lungs to operate effectively. Computer usage for longer hours could limit most people from participati ng in other activities and could permanently lose the ability to walk (Oja and Parsons, 112). Amputations could also result from this problem. This problem could be averted by taking off some time to exercise the leg muscles for effective blood flow. On the other hand, computer usage improves the speed of working. Computers are the main electronic devices that support faster processing of data in any given organization. This means that transactions and information is processed at a faster rate for effective decision making in the organization. Use of computers ensures that vital business opportunities are not missed by the organization. This could in turn lead to faster implementation of all the organizational activities for the achievement of goals and objectives. The required information between various departments can also be relayed faster hence boosting the speed at which efforts are coordinated form the achievement of results. Computers improve the general speed of working and communication in the organization thus improving the organizations performance. The speed at which computers work would enable the management saves a lot because only a few individuals are required to operate the computers. Individual efforts in ensur ing that speed is achieved are minimized as the computers perform all the tasks. This ensures that people are less tired hence reducing the level of negative effects on their health. Computers promote accuracy in the organizations. Computers contribute to the accuracy of different documents in the organization. They are not prone to errors like humans. They could calculate technical situations and effectively detect errors. This ensures that an organization is in a good position to make sound decisions with accurate information. Their output is reliable because of its accurate nature. The accurate information provided by computers is vital to the management as it gives the organizations correct picture for decision- making. Accuracy is enhanced by the set of programs that are installed in these computers. Opponents claim that it eases human stress by reducing their levels of reasoning concerning the accuracy of information. In addition, the accuracy of the information enhances reliability on the information. The management is in a better position to put in place corrective measures in cases where errors occur because the information gives the proper direction. In conclusion, continuous computer usage poses many health problems but their usage cannot be stopped because of their positive side. Computer users are likely to be exposed to many problems that result in permanent loss of their vital body parts. For instance, individuals exposed to back problems are unable to perform other activities that require the support of the back. They are unable to bend and perform other tasks hence leading to inefficiency in the utilization of activities. Individuals lose their eyesight resulting to a generation that is unable to see. The loss of eyesight means individuals are unable to read or write in the normal course of their lives. On the other hand, computers promote the speed of working and ensure that accuracy of the output is achieved. Computer usage for longer periods is generally harmful to an individuals health.

Entre Nos Essay Example | Topics and Well Written Essays - 1000 words

Entre Nos - Essay Example The movie proves to us that lack of immigrants’ cultural understanding, close friendship and interpersonal relationship in a city results to frustrations, mistreatment and suffering of immigrants in the cities. As Zukin (1995) analyzes, culture is a powerful tool for controlling cities. Culture is a summation of social, economic, linguistic, and political aspects of life and how people in a particular setting execute these components in their unique way. The video is an account of an experience by Mariana; a wife and mother of two young children, Gabriel and Andrea. Mariana’s husband, whom they have immigrated to live with in New York City, abandoned the naive family at the city. Unable to settle bills, Mariana is evacuated from their rented apartment to the streets and things get worse when she discovers that she is pregnant. In addition to her lack of knowledge of the language spoken in the vicinity, she has not employment or work experience. Language is a powerful to ol in life and immigrants are sometimes constrained and limited when they can not express themselves in the middle of strangers. Inability to understand the language of New York makes it difficult for the family to adapt to the culture of the city given that culture is inculcated largely through language. One of the inevitable thing that city immigrants should establish is social network; a powerful tool that members of the society can use for survival. In the vast urban environment, such as that of New York where Mariana and her two kinds were struggling to survive, social network could have been a way of soliciting for support from friends and neighbors. For example, immigrants should have a way of communicating and associating with their fellow immigrants, neighbors or those close to them. For example, if Mariana had known another fellow immigrant in the town, she could have been assisted because not all immigrants suffered the tragedy. In fact, the story would have been differen t if her husband stayed and continued to support his family. Another survival tactic, which ensures safety and security when one gets to a vast urban environment is creating close friendships with the people one is close to; either neighbors, workmates or associates. Close friendships makes a person to acquire and amass enough social, political and even economic security because friends can help in finding a solution in extreme cases instead of learning the hard way like Mariana. Moreover, close friendship is a significant part of social life and, as noted from the movie, much of the agonies that Mariana and her two kids underwent were as a result of lack of close friendship. As it is known, men are created solitary beings, but necessity forces them to create social networks because there is no survival in isolation. In this case, cities are depicted in an influential cinema as tragic places where people are not concerned much about their neighbors. In cities like the one Mariana wa s living, the owners of property such as tenants in urban areas are exceptionally capitalistic, and they are only concerned with their economic gains and not social welfare of their tenants; it is an economic regime that does not consider those who do not have. Economic challenges are, therefore, not a concern of the owners of resources in cities. For example, we see the owner of the apartment where Mariana and

Reflection on christianity Essay Example | Topics and Well Written Essays - 250 words

Reflection on christianity - Essay Example Loving the Lord God with all the heart, mind and soul is expounded in the law given to Moses where people are supposed to honor God first and foremost. Making graven images for people to worship is an act of dishonor to the God who made all things therefore, God commanded against it. Moreover, God teaches the people not to dishonor Him with their words but to praise Him with their lips instead and also to follow his footsteps, resting on the The second greatest commandment on the other hand encompasses the other commandments in the Law of Moses. It instructs the people how they are supposed to show their love and respect to each other by not murdering, slandering, nor committing adultery.

Since undoubtedly, everyone would want to be loved, the second commandment simply says to love other people as one would love

Effective Research Essay Example for Free

Effective Research Essay Research is a structured and systematic approach of looking for answer to questions and producing intended results. The methods used to research a particular topic should directly relate to the aims described in the topic. One should develop a clear, thoughtful, and organized study plan that tests the vital hypothesis. Describe any work concept, tools, and approaches for the anticipated studies. Discuss the possible limitations and difficulties of the anticipated procedures and alternative advances to achieve the aims. Tim Ireland (2008) adds that a tentative sequence for the project ought to be given. An overview of the conceptual framework and proposed design should be included. Study goals ought to relate to the projected hypothesis. Required statistical techniques, proposed timeline, and work plan should be included. Finally, one should be clear about the methods and investigation design used and should avoid correlative experiments. The ways of assessing and evaluating ones research is by checking for correct spelling, general neatness, parts in a reasonable and correct order with nothing missing, proper citation of borrowed material and the support of any arguments or thesis materials with evidence. One can also use rubric; it allows one to see what excellent, acceptable, good, and poor work looks like. Information from research is included in writing by putting all your gathered information together in a presentable format. One should put all his/her notes together according to the order they will come into view in their project (Albert and Podgy 1984). Another is strategy is the use of paraphrasing where one only uses the most important words, synonyms, and highlights and crosses out words (Ireland, 2008). Paraphrase: A good university should focus on equipping students with critical and analytical skills which form an integral part of what is expected of higher learning (Zein 2008).

Environmental Causes of Schizotypal Personality Disorder :: essays research papers

The Environmental Causes of Schizotypal Personality Disorder   Ã‚  Ã‚  Ã‚  Ã‚   Schizotypal personality disorder (SPD), is considered by many as part of the schizophrenic spectrum. It is characterized by discomfort with other people, peculiar patterns of thinking and behavior, and eccentricity. These may take the form of cognitive or perceptual disturbances. Yet, unlike schizophrenia, these psychotic symptoms are not as fully developed as delusions or hallucinations but instead can be characterized as perceptual illusions. A person suffering from SPD might become extremely anxious in social situations, especially those involving strangers. Schizotypal patients also tend to be overly suspicious of others and are not prone to trust others or to relax in their presence. Another characteristic of the disorder is that schizotypes are often odd and eccentric. They often harbor absurd superstitions such as a belief in ESP and many other psychic or paranormal phenomenons that are outside the boundaries of accepted thought. In some cases Schizotypes believe that they possess magical powers, such as the ability to control other people with their thoughts. (Buss 2002) As a result of these symptoms, people diagnosed with SPD have great difficulty with social relationships, and are often alienated from mainstream society. This paper aims to investigate the suspected causes of this strange disorder, focusing on environmental and hereditary factors.   Ã‚  Ã‚  Ã‚  Ã‚  Some recent studies have found a correlation between the use of street drugs and instances of SPD. Researchers in New Zealand found that people who commonly used cannabis were more than three times as likely to develop schizophrenia and or schizotypal disorder later in life. There have been 30 published research experiments linking cannabis to these disorders. The increase in this evidence during the past decade has been attributed to increases in the potency of marijuana. (Allebeck 1993)   Ã‚  Ã‚  Ã‚  Ã‚  Some street drugs are credited with not only increasing the risk of developing SPD, but actually in some cases have triggered the onset of the disorder. SPD and schizophrenia can some times be brought on by heavy use of hallucinogenic drugs, especially LSD; but it appears that a person has to have a predisposition towards developing SPD for this to occur. There is also some evidence suggesting that a person suffering from SPD but undergoing treatment can have a relapse episode by taking LSD. Methamphetamine and PCP are also known to mimic the symptoms of SBD, and can therefore bring about symptoms of the disorder without a previous diagnosis. (Allebeck) Some other research has found that enriched educational, nutritional and social environments substantially lower the risk of developing SPD.

Leadership Challenges Of Today Essay

The role of leaders today has become increasingly easier and yet more challenging at the same time.   With the level of technology that is available today as opposed to what was previously available, a leader is able to communicate much faster with the other members of the team and coordinate the work within large teams more effectively and efficiently (Bennis, 2001).    With the advances in communication technologies and all the new gadgets designed to ease to work load and make people function for efficiently, there are more and more demands of a leader today.   Factor in the fact that there are an increasing number of multi-cultural working environments today and it becomes apparent just how much more different the leadership scene is today from previous years (Bennis, 2001).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   One of the main challenges of a leader today that has been brought about by the development of technology is that a leader is now expected to do more.   A leader is always expected to make the most of whatever resources are available (Covey, 1999).   In previous years, the constraints of communication problems made the expectation much lower than it is today.   With the relative ease in communication and the devices that are currently available, more output is expected from a leader.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another challenge which was not present in the leadership scene in previous years is the existence of a growing number of multi-cultural teams in the work place.   The diverse environments in the work place today demand that a leader be able to cope with the different cultural background and communication skills of his team members (Bennis, 2001).   This creates a more challenging working environment as leaders must try to adjust to the needs of working in a multi-cultural environment.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Finally, with the level of competition brought about by globalization, it is becoming increasingly difficult for leaders to cultivate a company culture that promotes job satisfaction and reduces the turnover rate of employees.   The relative ease of finding other jobs in other companies and markets and the level of competition demands that a leader must be able to play a critical role in keeping the team members happy as well as ensuring a certain level of productivity to remain competitive (Covey, 1999).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   While it may be argued that these leadership challenges were already present in the workplace before, it must be pointed out that these challenges only existed to a minimal extent and were not a major factor until now.   It is expected that as the world markets expand and the level of competition increases, the role of a leader today will only become more challenging and stressful.

Public Relation Core Values Essay

Public Relations Society of America (PRSA) has extremely important core ethical values that include advocacy, honesty, expertise, independence, loyalty, and fairness. All of which will help further a public relations practitioner in their career. Every practitioner handles every job differently, in a way thats going to benefit both the company they are working for as well as the public. Honesty should be the most important core value for every practitioner. Not only should it be the most important core value in the work field, it should also be the most important core value in everyones life as well. On the other hand, practitioners tend to ignore their core values while working. One of the biggest values they tend to ignore or overlook is fairness. Mark Twain once said, â€Å"Honesty is the best policy; when there is money in it. This quote should be every public relations practitioner motto because being honest will always lead you to conducting better business with clients. Clients want honest individuals working for them because the company expects the practitioner to represent the company in a way thats going to gain the publics trust. When the public has your trust, they are going to shop at your company rather than one who puts out false advertisement and has a poor look in the publics eyes. Not only does the quotes speak for itself, but honesty is simply the best way to conduct business. Some practitioners try their hardest to provide equally fair service to every client. Fairness is a core value that all practitioners respect but is hard to do at times. When dealing with clients, employers, peers,vendors, competitors, and most important the public, its hard to keep everyone happy. Lets say a practitioner is dealing directly with a company for the release of a new product. The company producing the item may not want competitors knowing about it so they can keep the technological edge on its competitors but also at the same time they want the public to hear about what’s new. Since they manage what information the public hears, its essential what they say. No matter what they say or don’t say, someones always going to want more. With that being said, someone’s not going to be happy. Life in general isn’t always fair, so when faced with a situation that can cause grey areas with others, do what you ethically think is the right thing.

Recruitment and Selection Strategies Essay Example | Topics and Well Written Essays - 2500 words

Recruitment and Selection Strategies - Essay Example It starts with the hunt for new employees and it continues till a pool of application is generated out of which new employees are selected. To develop a good strategy an organization an organization should always keep itself updated on the opening that are present in it , openings that may be required and positions that are potentially going to be vacant in the future. An organization should target the positions needed immediate fillings first, but it is best to predict the vacancies and plan for recruitment as this ensures that the quality of recruitment activities stays good. Requirements for a certain type of position should be fully understood for better recruitment. The performance level required, the experience needed by the potential employee should ne properly be established. The organization should identify that the vacant post can be best filled by external recruitment or internal recruitment. Some organizations feel that employee referrals are very effective forms of recruitment source (Lisa Guerin, 2007). Vacancies are mostly properly advertised. Human resources personnel involved in recruitment should have proper training and experience so that they can judge the skills and parameters required for the job and determine if they are present in the candidate or not. Evaluation methods of candidates should be described (Linda L. Neider, 2003). The most popular evaluation methods are written tests, interviews, psychometric tests (Carter, 2004) or a combination of these. Things that affect the recruitment process are the organizations objectives and policies, the government policies and labor laws, the source of recruitment traditionally used by an organization, the current needs of the organization and the costs affiliated with the recruitment (Rouse, 2007) The recruitment challenges faced by organizations are that the labor in some countries has aged and the pension costs are becoming high. In the modern day the organizations invite employees from all around the world (Hook, 2008), to generate a larger candidate pool the organizations use modern sources like outsourcing. Organizations outsource their recruitment activities to another organization which screens candidates initially according to organizational requirements given to it so that its employer organization can select employees from its screened candidate pool (Ian Beardwell, 2007). The advantage of this is that even if the company is not planned for a vacancy it can forward its need to the outsourcing organization and get a desired employee in lesser amount of time. It also creates competitive advantage by speeding up the process of recruitment; it helps the management to stay focused on other things rather then the generation of a candidate pool. These organizations usually negotiate salaries on the behalf of their employers to save time and resources of its employers. Poaching and raiding is also another way of acquiring talent, in this the organizations attract and employee a person who is already an

How can cities become more sustainable Compare and contrast cities in Essay - 1

How can cities become more sustainable Compare and contrast cities in the developed world and cities in the developing world - Essay Example Most of these cities had less than one million population in the beginning of 19th century; that surpassed to more than 10 millions in subsequent periods causing great distress on resources of water, clean air, energy. Situation in some of the cities in developing countries such as Shanghai, Mumbai or Sao Paulo is different. The density of these urban centers is more than double of that seen in the London or New York. All these cities are growing at the rate of 2 to 6 percent per annum and likely to cause further stress on the resources and derail the ecosystem. If this continues, the sustainability of the cities is in jeopardy unless some new ways are found. Cities in the Developed World London, Paris, California, New York all have become the huge unrestrained consumption centers of cheap energy and profligate material supplies that has caused ecological imbalances in those countries. As mentioned by Rees, William (2009) in Scientific American in its March issue, â€Å"Politicians and planners have shaped cities with no regard for resource use or ecological concerns. Over the years building and infrastructure have consumed more than 40 percent of material and a third of energy.† He warns that all this must end. ... Rees is of the opinion that sprawling land areas for living increase the energy need by way of unnecessary transportation for work and shopping. Reliance on automobiles and cars should be reduced by providing path ways for cycling, and walking. Public transport system should be made efficient to avoid the use of personal vehicles. Recycling of used materials is a necessity and that should be done to lessen the use of fresh material so that natural resources can be conserved for a longer period of time. Cogeneration of electricity and waste heat recovery is need of a day to reduce per capita consumption of fresh energy. Energy efficiency and renewable energy are the good propositions but the big question is that city like San Francisco releases 78 percent of its greenhouse gases from the cars and transportation and only 17 percent from buildings and this is true for all major cities of North America. The solution essentially lies at using mass transit system and eliminating the use of personal vehicles as much as possible. Personal vehicle density in most of the US cities is so high that this is a single most cause of green house gases across all major US and cities of Europe. And solution lies in reducing or eliminating the use of these personal vehicles that can help reduce the green house emissions drastically and put the eco system in balance. Cities of Developing World In contrast to the cities of developed economies, there are cities of developing countries such as Sao Paulo, Shanghai, and Mumbai, where issues are, more than green house gases, inadequate availability of potable water, absence of proper sanitation facilities to slum dwellers, and cleanliness. More than one million people is said to have been living in slum area within
