Computer Ethics and Information Systems

â€Å"Computer Ethics and Information Security† a. Introduction The consideration of computer ethics fundamentally emerged with the birth of computers. There was concern right away that computers would be used inappropriately to the detriment of society compromising information security, or that they would replace humans in many jobs, resulting in widespread job loss. Ethics- Guidelines or rules of conduct that govern our lives, work, behavior and communication in both public and private undertaking. Ethics are a set of moral principles that govern an individual or a group on what is acceptable behaviour while using a computer.Computer ethics is a set of moral principles that govern the usage of computers. One of the common issues of computer ethics is violation of copyright issues. Duplicating copyrighted content without the author’s approval, accessing personal information of others are some of the examples that violate ethical principles. Security – is the deg ree of protection to safeguard a nation, union of nations, persons or person against danger, damage, loss, and crime. Security as a form of protection are structures and processes that provide or improve security as a condition.Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction Computer Ethics- is a branch of practical philosophy which deals with how computing professionals should make decisions regarding professional and social conduct. b. Discussion Computer Ethics Ethics deals with placing a â€Å"value† on acts according to whether they are â€Å"good† or â€Å"bad†. Every society has its rules about whether certain acts are ethical or not.These rules have been established as a result of consensus in society and are often written into laws. When computers first began to be used in society at large, the absence of ethical s tandards about their use and related issues caused some problems. However, as their use became widespread in every facet of our lives, discussions in computer ethics resulted in some kind of a consensus. Today, many of these rules have been formulated as laws, either national or international. Computer crimes and computer fraud are now common terms. There are laws against them, and veryone is responsible for knowing what constitutes computer crime and computer fraud. The Ten Commandments of computer ethics have been defined by the Computer Ethics Institute. Here is our interpretation of them: 1) Thou shalt not use a computer to harm other people: If it is unethical to harm people by making a bomb, for example, it is equally bad to write a program that handles the timing of the bomb. Or, to put it more simply, if it is bad to steal and destroy other people’s books and notebooks, it is equally bad to access and destroy their files. ) Thou shalt not interfere with other people's computer work: Computer viruses are small programs that disrupt other people’s computer work by destroying their files, taking huge amounts of computer time or memory, or by simply displaying annoying messages. Generating and consciously spreading computer viruses is unethical. 3) Thou shalt not snoop around in other people's files: Reading other people’s e-mail messages is as bad as opening and reading their letters: This is invading their privacy. Obtaining other people’s non-public files should be judged the same way as breaking into their rooms and stealing their documents.Text documents on the Internet may be protected by encryption. 4) Thou shalt not use a computer to steal: Using a computer to break into the accounts of a company or a bank and transferring money should be judged the same way as robbery. It is illegal and there are strict laws against it. 5) Thou shalt not use a computer to bear false witness: The Internet can spread untruth as fast as it can spread truth. Putting out false â€Å"information† to the world is bad. For instance, spreading false rumors about a person or false propaganda about historical events is wrong. ) Thou shalt not use or copy software for which you have not paid: Software is an intellectual product. In that way, it is like a book: Obtaining illegal copies of copyrighted software is as bad as photocopying a copyrighted book. There are laws against both. Information about the copyright owner can be embedded by a process called watermarking into pictures in the digital format. 7) Thou shalt not use other people's computer resources without authorization: Multiuser systems use user id’s and passwords to enforce their memory and time allocations, and to safeguard information.You should not try to bypass this authorization system. Hacking a system to break and bypass the authorization is unethical. 8) Thou shalt not appropriate other people's intellectual output: For example, the programs you write for the projects assigned in this course are your own intellectual output. Copying somebody else’s program without proper authorization is software piracy and is unethical. Intellectual property is a form of ownership, and may be protected by copyright laws. ) Thou shalt think about the social consequences of the program you write: You have to think about computer issues in a more general social framework: Can the program you write be used in a way that is harmful to society? For example, if you are working for an animation house, and are producing animated films for children, you are responsible for their contents. Do the animations include scenes that can be harmful to children? In the United States, the Communications Decency Act was an attempt by lawmakers to ban certain types of content from Internet websites to protect young children from harmful material.That law was struck down because it violated the free speech principles in that country's constitution. T he discussion, of course, is going on. 10) Thou shalt use a computer in ways that show consideration and respect: Just like public buses or banks, people using computer communications systems may find themselves in situations where there is some form of queuing and you have to wait for your turn and generally be nice to other people in the environment. The fact that you cannot see the people you are interacting with does not mean that you can be rude to them. Ethical Issues :- †¢Computers in the Workplace Computer Crime †¢ Privacy and Anonymity †¢ Intellectual Property †¢Professional Responsibility †¢Globalization Computers in the Workplace. Computers can pose a threat to jobs as people feel they may be replaced by them. However, the computer industry already has generated a wide variety of new jobs. When computers do not eliminate a job, they can radically alter it. In addition to job security concerns, another workplace concern is health and safety. It is a computer ethics issue to consider how computers impact health and job satisfaction when information technology is introduced into a workplace.Computer Crime. With the proliferation of computer viruses, spyware, phishing and fraud schemes, and hacking activity from every location in the world, computer crime and security are certainly topics of concern when discussing computer ethics. Besides outsiders, or hackers, many computer crimes, such as embezzlement or planting of logic bombs, are committed by trusted personnel who have authorization to use company computer systems. Privacy and Anonymity. One of the earliest computer ethics topics to arouse public interest was privacy.The ease and efficiency with which computers and networks can be used to gather, store, search, compare, retrieve, and share personal information make computer technology especially threatening to anyone who wishes to keep personal information out of the public domain or out of the hands of those who are perce ived as potential threats. The variety of privacy-related issues generated by computer technology has led to reexamination of the concept of privacy itself. Intellectual Property. One of the more controversial areas of computer ethics concerns the intellectual property rights connected with software ownership.Some people, like Richard Stallman, who started the Free Software Foundation, believe that software ownership should not be allowed at all. He claims that all information should be free, and all programs should be available for copying, studying, and modifying by anyone who wishes to do so. Others, such as Deborah Johnson, argue that software companies or programmers would not invest weeks and months of work and significant funds in the development of software if they could not get the investment back in the form of license fees or sales.Professional Responsibility and Globalization. Global networks such as the Internet and conglomerates of business-to-business network connecti ons are connecting people and information worldwide. Such globalization issues that include ethics considerations include: †¢Global laws †¢Global business †¢Global education †¢Global information flows †¢Information-rich and information-poor nations †¢Information interpretation The gap between rich and poor nations, and between rich and poor citizens in industrialized countries, is very wide.As educational opportunities, business and employment opportunities, medical services, and many other necessities of life move more and more into cyberspace, gaps between the rich and the poor may become even worse, leading to new ethical considerations. Common Computer Ethics Fallacies Although computer education is starting to be incorporated in lower grades in elementary schools, the lack of early computer education for most current adults led to several documented generally accepted fallacies that apply to nearly all computer users.As technology advances, these f allacies will change; new ones will arise, and some of the original fallacies will no longer exist as children learn at an earlier age about computer use, risks, security, and other associated information. There are more than described here, but Peter S. Tippett identified the following computer ethics fallacies, which have been widely discussed and generally accepted as being representative of the most common. The Computer Game Fallacy. Computer users tend to think that computers will generally prevent them from cheating and doing wrong.Programmers particularly believe that an error in programming syntax will prevent it from working, so that if a software program does indeed work, then it must be working correctly and preventing bad things or mistakes from happening. Even computer users in general have gotten the message that computers work with exacting accuracy and will not allow actions that should not occur. Of course, what computer users often do not consider is that although the computer operates under very strict rules, the software programs are written by humans and are just as susceptible to allowing bad things to happen as people often are in their own lives.Along with this, there is also the perception that a person can do something with a computer without being caught, so that if what is being done is not permissible, the computer should somehow prevent them from doing it. The Law-Abiding Citizen Fallacy. Laws provide guidance for many things, including computer use. Sometimes users confuse what is legal with regard to computer use with what is reasonable behavior for using computers. Laws basically define the minimum standard about which actions can be reasonably judged, but such laws also call for individual judgment.Computer users often do not realize they also have a responsibility to consider the ramifications of their actions and to behave accordingly. The Shatterproof Fallacy. Many, if not most, computer users believe that they can do littl e harm accidentally with a computer beyond perhaps erasing or messing up a file. However, computers are tools that can harm, even if computer users are unaware of the fact that their computer actions have actually hurt someone else in some way. For example, sending an email flame to a large group of recipients is the same as publicly humiliating them.Most people realize that they could be sued for libel for making such statements in a physical public forum, but may not realize they are also responsible for what they communicate and for their words and accusations on the Internet. As another example, forwarding e-mail without permission of the author can lead to harm or embarrassment if the original sender was communicating privately without expectation of his message being seen by any others. Also, using e-mail to stalk someone, to send spam, and to harass or offend the recipient in some way also are harmful uses of computers.Software piracy is yet another example of using computers to, in effect, hurt others. Generally, the shatterproof fallacy is the belief that what a person does with a computer can do minimal harm, and only affects perhaps a few files on the computer itself; it is not considering the impact of actions before doing them. The Candy-from-a-Baby Fallacy. Illegal and unethical activity, such as software piracy and plagiarism, are very easy to do with a computer. However, just because it is easy does not mean that it is right.Because of the ease with which computers can make copies, it is likely almost every computer user has committed software piracy of one form or another. The Software Publisher's Association (SPA) and Business Software Alliance (BSA) studies reveal software piracy costs companies multibillions of dollars. Copying a retail software package without paying for it is theft. Just because doing something wrong with a computer is easy does not mean it is ethical, legal, or acceptable. The Hacker's Fallacy.Numerous reports and public ations of the commonly accepted hacker belief is that it is acceptable to do anything with a computer as long as the motivation is to learn and not to gain or make a profit from such activities. This so-called hacker ethic is explored in more depth in the following section. The Free Information Fallacy. A somewhat curious opinion of many is the notion that information â€Å"wants to be free,† as mentioned earlier. It is suggested that this fallacy emerged from the fact that it is so easy to copy digital information and to distribute it widely.However, this line of thinking completely ignores the fact the copying and distribution of data is completely under the control and whim of the people who do it, and to a great extent, the people who allow it to happen. Hacking and Hacktivism Hacking is an ambivalent term, most commonly perceived as being part of criminal activities. However, hacking has been used to describe the work of individuals who have been associated with the open -source movement. Many of the developments in information technology have resulted from what has typically been considered as hacking activities.Manuel Castells considers hacker culture as the â€Å"informationalism† that incubates technological breakthrough, identifying hackers as the actors in the transition from an academically and institutionally constructed milieu of innovation to the emergence of self-organizing networks transcending organizational control. A hacker was originally a person who sought to understand computers as thoroughly as possible. Soon hacking came to be associated with phreaking, breaking into phone networks to make free phone calls, which is clearly illegal.The Hacker Ethic. The idea of a hacker ethic originates in the activities of the original hackers at MIT and Stanford in the 1950s and 1960s. Stephen Levy outlined the so-called hacker ethic as follows: 1. Access to computers should be unlimited and total. 2. All information should be free. 3. A uthority should be mistrusted and decentralization promoted. 4. Hackers should be judged solely by their skills at hacking, rather than by race, class, age, gender, or position. 5. Computers can be used to create art and beauty. . Computers can change your life for the better. The hacker ethic has three main functions: 1. It promotes the belief of individual activity over any form of corporate authority or system of ideals. 2. It supports a completely free-market approach to the exchange of and access to information. 3. It promotes the belief that computers can have a beneficial and life-changing effect. Such ideas are in conflict with a wide range of computer professionals' various codes of ethics. Ethics Codes of Conduct and ResourcesSeveral organizations and groups have defined the computer ethics their members should observe and practice. In fact, most professional organizations have adopted a code of ethics, a large percentage of which address how to handle information. To prov ide the ethics of all professional organizations related to computer use would fill a large book. The following are provided to give you an opportunity to compare similarities between the codes and, most interestingly, to note the differences and sometimes contradictions in the codes followed by the various diverse groups. Information SecurityInformation security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction Information Security Attributes: or qualities, i. e. , Confidentiality, Integrity and Availability (CIA). Information Systems are decomposed in three main portions, hardware, software and communications with the purpose to help identify and apply information security industry standards, as mechanisms of protection and prevention, at three levels or layers: physical, personal and organizational.Essentially, procedures or policies are implemented to tell people (administrators, users and operators)how to use products to ensure information security within the organizations. Confidentiality Confidentiality is the term used to prevent the disclosure of information to unauthorized individuals or systems. For example, a credit card transaction on the Internet requires the credit card number to be transmitted from the buyer to the merchant and from the merchant to a transaction processing network.The system attempts to enforce confidentiality by encrypting the card number during transmission, by limiting the places where it might appear (in databases, log files, backups, printed receipts, and so on), and by restricting access to the places where it is stored. If an unauthorized party obtains the card number in any way, a breach of confidentiality has occurred. Confidentiality is necessary (but not sufficient) for maintaining the privacy of the people whose personal information a system holds. [citation needed] IntegrityIn information security, integrity means that data cannot be modified undetectably. [citation needed] This is not the same thing as referential integrity in databases, although it can be viewed as a special case of Consistency as understood in the classic ACID model of transaction processing. Integrity is violated when a message is actively modified in transit. Information security systems typically provide message integrity in addition to data confidentiality. Accessibility For any information system to serve its purpose, the information must be available when it is needed.This means that the computing systems used to store and process the information, the security controls used to protect it, and the communication channels used to access it must be functioning correctly. High availability systems aim to remain available at all times, preventing service disruptions due to power outages, hardware failures, and system upgrades. Ensuring availability also involves preventing denial-of-service attacks. Authent icity In computing, e-Business, and information security, it is necessary to ensure that the data, transactions, communications or documents (electronic or physical) are genuine.It is also important for authenticity to validate that both parties involved are who they claim they are. Non-repudiation In law, non-repudiation implies one's intention to fulfill their obligations to a contract. It also implies that one party of a transaction cannot deny having received a transaction nor can the other party deny having sent a transaction. Electronic commerce uses technology such as digital signatures and public key encryption to establish authenticity and non-repudiation. c. ConclusionImpact of Computer Ethics on Information Security The relationship between information security and computer ethics does not look, on the surface, readily obvious, and even appears remote. It is, however, credible. Culture, customs, trust and privacy that characterize security fall within the realm of ethics. Computer ethics alert information security management to ethical considerations and warn potential offenders of ethical consequences in situations where the technical tools or the legal measures fail.In these cases, an ethical decision may be helpful in bringing about a solution. Furthermore, this conclusion is consistent with the following premises with respect to technical controls, computer laws and computer ethics: †¢Premise 1: The information security management community has applied control tools to meet the information security objectives of safeguarding confidentiality against unauthorized access, upholding integrity and maintaining availability. However, detecting computer crime is difficult, because the act is either traceless or difficult to trace.Quantifying the damage is problematic since the victims all too often withhold reporting the crime for reasons including fear of recrimination and bad publicity. 8 Therefore, the technical control tools are ineffective, wi th respect to legal issues. †¢Premise 2: Computer laws have been enacted in various nations at an ever-increasing rate since the late 1980s, when business and the society at large were forced to face the magnitude and severity of damage not experienced prior to computer crimes. There has been a dramatic increase in specialized legislation to combat criminal behaviors related to computer crime, which include traditional crimes committed with the use of a computer and a variety of new, technologyspecific criminal behaviors spawned by the rapid emergence of computer technologies and the exponential expansion of the Internet. 10 However, despite the additional new laws, prosecution is deterred because the legal proceeding is a tardy, time-consuming and expensive process, even when there are well-justified intentions to proceed with legal action.Also, legislation always lags behind the event such that either no appropriate laws are found or the new law is too late for the case in ha nd. Hence, computer laws are at best a deterrent to computer crime, not a guardian of information. †¢Premise 3: Computer ethicists assert, on the one hand, that special ethical issues are raised because computers are special technology, and query, on the other hand, why there should be computer ethics since, for example, there is no such thing as telephone ethics even though the telephone is a special technology that makes a profound change on the way individuals communicate with others. 1 However, information security is worthy of ethical consideration as many decisions in information technology affect a wide range of stakeholders. National and international computer societies have promoted codes of ethical practice and even written these codes into their constitutions. As technology advances, computers continue to have a greater impact on society.Therefore, computer ethics promotes the discussion of how much influence computers should have in areas such as information securit y, artificial intelligence and human communication. As the world of computers evolves, computer ethics continues to create ethical standards that address new issues raised by new technologies.

Pros Cons of Free Trade Essay

I think Free Trade has its good and it’s bad. A good example is, the Auto industry. Here in Indiana we have a lot of foreign auto manufactures such as Subaru, Toyota, and Honda, just to name a few. As for American there is Chrysler and Ford. This can decrease the value of the American car, because of all the choices from the foreign market. This could eventually cause a loss of sales and money for the American manufactures, which could cause layo%s and loss of income for their employees in the future. However, overall the advantages of free trade de&nitely outweigh the disadvantages, by crea’ng more jobs. Pro â€Å"Indiana workers need trade to maintain and create jobs. In 2010, 761,500 jobs in Indiana depend on trade. In 2008, 20. 5 percent of jobs in Indiana depended on trade, up from 10. 0 percent from 1992. Indiana’s trade-related employment grew more than &ve ‘mes faster than total employment from 2004 to 2008. †(Business Roundtable, 2010). Con â€Å"Free trade is a convenient, well-packaged ideology that resonates well with consumers, and lines the pockets and ambi’ons of CEO’s and poli’cians. † (He%ner, Thomas, May 2012) As a result, in Indiana and the US nearly 50 percent of all new cars now sold are foreign. Unfortunately, because of Free Trade more people think buying an American product is cheap or not good quality. As a result of this the middle-class that rely on an American industry for employment and opportunity is being destroyed and falling further into debt.

Managing & Enhancing Care in Rapidly Changing & Complex Situations Leadership Essay

Introduction to the folder of Evidence This assignment is an analysis of my leadership development though my training, and to assist me to adapt from a student nurse to a staff nurse confidently. This, along with an action plan (appendix 1) is completed though out my module 8 placement in accident and emergency. My leadership skills are developed by shadowing my mentor whilst she is in charge of shifts for 3 weeks, as well as accurately and confidently handing over patients to other members of the multi-disciplinary team. In this setting, skills such as communication, decision making, prioritising care and time management are necessary, therefore this placement has assisted me in developing those skills. This assignment relates to learning outcome 2-Utilise a range of therapeutic approaches and problem solving skills when planning, implementing and evaluating care to enhance quality of life for patients and carers, 3- Utilise effective coaching skills in the support of patients, carers and less experienced colleagues, and 4- Analyse and develop professional care, management and leadership roles within the context of multidisciplinary and collaborative care delivery in meeting health and social care needs for patients with increasing levels of dependency. (MSG, 2011) I will develop my leadership skills by shadowing her whilst she is triaging patients, in charge of shifts, and when she is handing over, along with accurate communication skills. Though out the placement, I will gain feedback from my mentor on my progress in order to help me to achieve sufficient leadership skills. Introduction The aim of this reflective account is to analyse leadership skills that have been developed throughout my module 8 placement in Accident and Emergency. I will debate the motives for my choice of actions, and evaluate the extent which it has enabled me to improve my leadership skills. I will discuss what I have discovered about my leadership skills, how I’ve developed as a leader, and what effect this has on the care given to my patients. This assignment, in collaboration with the practise assessment document, will assist me in identifying skills developed, with significance to learning outcomes 2, 3, and 4. The identified skills along with leadership literature will be evaluated using the Gibbs Reflective Cycle (1988) which comprises of description, feelings, evaluation, analysis, conclusion, and action plan. There are many definitions of leadership, such as being a ‘’function of knowing yourself, having a vision that is well communicated, building trust among colleagues, and taking effective action to realize your own leadership potential ‘’. (Bennis, 1959), ‘Leadership involves the use of interpersonal skills to influence others to accomplish a specific goal.’ (Sullivan and Garland, 2010). All of these definitions gave me a great idea of leadership, and allowed me to choose an aspect of leadership skills within my placement. This allowed me to focus on my leadership skills whilst making decisions in the clinical setting. Clinical decision-making is a process that nurses undertake on a daily basis when they make judgements about the care that they provide to patients and management issues. (Banning, 2007). NMC 2008 states that you must ‘‘Provide a high standard of practice and care at all times’’. This reflective account is also based on my leadership skills whilst leading handover. Clinical handover refers to the transfer of information from one health care provider to another when a patient has a change of location or venue of care, and/or when the care of/responsibility for that patient shifts from one provider to another (ACSQHC, 2005). The NMC (2008) states that ‘’you should be aware of, and develop, your ability to communicate effectively within teams. The way you record information and communicate is crucial. Other people will rely on your records at key communication points, especially during handover, referral and in shared care.’’ Stage 1: Description of the event Decision making plays an important role in the A&E department. This determines the care each patient receives. My mentor asked me to triage a patient in the minors department. No names are mentioned in this piece in order to respect dignity and privacy as stated by the NMC (2008). I began to triage a 29 year old female who presented with abdominal pain and vaginal bleeding. This patient was 7 weeks pregnant. As I was assessing the patient I noticed that she was hypotensive at a blood pressure of 95/65. Following this, I informed my mentor of my patient and my findings. Following a discussion with my mentor, we decided that this patient was high priority. Whilst my mentor inserted a cannula and took bloods, I was given the responsibility of allocating the patient to a bed. Following the discussion with my mentor, I felt that it was necessary to place the patient in majors, and on a monitor bed. As this was being put into action, my mentor and I noticed that all monitored beds were tak en up. I then had to liaise with the nurse in charge to decide if all patients on the monitored beds were required to stay on monitors. After organising a monitor bed for the patient, I then bleeped the gynecologist on call for further advice. After the patient was assessed by other members of the multi-disciplinary team, it was decided that the patient was to be admitted for further tests, as the gynecologist was querying an ectopic pregnancy. My mentor then allowed me to liaise with the bed manager to organise a bed on a suitable ward for the patient. After a bed was arranged, I then escorted the patient to the ward and gave a full handover to the nurses under my mentors supervision. Handover is another very important aspect of communication in the clinical setting, as it ensures the correct information is given to the nurse, and therefore, care for the patient will be organized accurately. Stage 2: Feelings When my mentor allocated me to triage patients, I felt that I was given a lot of responsibility. Porterfield (1999) states that empowering employees is an important part of employee development and can in turn produce a higher level of employee satisfaction. I questioned my ability to assess to as I was not used to this level of responsibility. I mentioned this to my mentor and she reassured me by discussing what assessment tools to use, and  mentioning that she and the rest of the nursing team were there for any guidance throughout the assessment. Once the patient was assessed and allocated to majors, I felt quite confident in my decision making skills. My mentor mentioned that I had triaged the patient successfully and competently and this was very reassuring. As I continued care for the patient, I became to feel more confident in the care I was providing. After a clinical decision was made and the patient was to be handed over to the nursing staff on the ward, I felt slightly nervous in regards to ensuring the correct and accurate information is being given to the staff, as well as the essential information in regards to the patient. As I proceeded to begin handover, I became more confident as I had been with this patient since the beginning, and had a good insight to the care that was given and the care that was to be given. I gave the nurses a full handover in regards to the patient, including what examinations were carried out and the results of the examinations, and what the patient is required in order to keep comfortable. I also mentioned that this was the patient’s first pregnancy and reassurance is vital. Following handover, my mentor gave me feedback on how I handed over the patient. We discussed my communication skills, and my mentor mentioned that I gave an accurate and well-spoken handover, and mentioned all relevan t information in regards to the patient. After receiving that feedback, I felt that my style of leadership tailed was transformational. Stage 3: Evaluation Leaders are often described as being visionary, equipped with strategies, a plan and desire to direct their teams and services to a future goal (Mahoney, 2001). Decision making is a fundamental element of nursing, and is essential to understand. (Reilly, 2003). By my mentor allowing me to make clinical decisions on patient care, leadership skills whilst making decisions were put into practice. With the support of my mentor and all the staff, I was able to analyze clinical situations and make a decision based on best practice, as well as evidence based practice. By gaining feedback from peers, it allowed me to evaluate how effective my decision making and communication skills were. Communication can be identified as a vast field with the nursing setting. (Donnelly and Neville, 2008). Throughout handover, my delivery of information was accurate and precise, and the level  of communication between the nursing staff receiving handover from I was approached to in a professional manner. I feel that, throughout the experience, my confidence levels were low and adverse. Dao (2008) states that self-confidence is the fundamental basis from which leadership grows. Although, I received positive feedback from peers, being given such important tasks made me doubt my competency as a nurse. Stage 4: Analysis The Gibbs et al (1988) reflective model encourages the analysis stage to break down the event into its components so they can be explored separately. In order to analyze, becoming aware of the variety of learning theories and styles will assist in evaluating. Timmins (2006) states that critical analysis should analyse current practice along with examining the research base of practice and exploring theories that update nursing. I feel by exploring various leadership styles, I achieved this throughout my placement. An effective leader should be able to adopt, either consciously or unconsciously, various leadership styles in various situations (Bennett et al. 2010). By approaching the range of leadership theories, I feel that I have obtained the transformational leadership technique. Transformational leadership style is made up of 4 elements, Idealized influence, Inspirational motivation, Intellectual stimulation, and Individual consideration. In comparison, Transactional leadership style is made up of 2 elements, Contingent Reward and management by exception. Aarons (2006) states transformational leadership inspires and motivates followers, whereas transactional leadership is based more on reinforcement and exchanges. I feel that I built a professional relationship with not only my mentor, but with other colleagues in the department, and had the support necessary to assist me in making decisions and handing over. In terms of patient’s safety, accurate decision making and hand over is an essential. The NMC (2008) states that you must ‘’provide a high standard of practice and care at all times’’. By obtaining a transformational leadership style, this ensures that whilst decision making, that all decisions are made with rationale and in the best interest of the patient. When handing information of care of patients over to colleagues, effective co-ordination and communication is essential. Clinical decision-making is a complex activity that requires practitioners to be knowledgeable in relevant aspects of  nursing, To have access to reliable sources of information and appropriate patient care networks and to work in a supportive environment. (O’Neill, Dluhy & Chin, 2005). However, although being supervised whilst making decisions and handing over, I was expected to do these tasks independently and professionally, and based on the best interest of the patient. This allowed me to gain further insight to the transition of student nurse to staff nurse. Stage 5: Conclusion In conclusion I feel the time I spent working within the Accident and Emergency team facilitated greatly in assisting me to develop my leadership skills. The stated event reflected best shows how I incorporated two aspects of my new leadership skills. I feel by studying the styles and skills involved in leadership I gained a good knowledge of leadership styles which I presented during my time here. I received feedback from my mentors and colleagues in regards to the skills, which have given me confidence to practice these skills in the future as a staff nurse. I have come to realise that a variety of leadership styles of leading best work in a hospital setting. In the future I will strive to further develop my leadership skills. Stage 6- Action Plan I plan to continue developing my leadership skills by observing and taking part in handover throughout the rest of my placements. I also hope to continue developing my decision making skills by shadowing my mentor and other colleagues throughout triaging and deciding patient care. As a self-regulated learner, I plan to gain feedback from both mentors and colleagues and focus on areas of further development. REFERENCES Aarons, G. (2006).

Introduction to the microbial world history of microbiology Essay

Part A. This letter is in response to your story which was published in your website and broadcasted in your stations regarding Edward Jenner as the most prolific microbiologist that ever lived and have contributed much to the improvement of microbiology and public health. I would like to make a point that several other scientists have contributed much to that of the works of Jenner on eradicating small pox virus by vaccination. He may have started the use of vaccines which led to its eradication years later; however, it should not be mistaken to be the most significant microbiological contribution. Take an example the work of Joseph Lister on 1867 regarding antiseptics (Prescott et al., 2005). Like any other scientist during his time, works on antisepsis was not an overnight job; he worked carefully and tested his theories over and over again, until such time that he perfected it (Roediger, 1990). By thoughtfully thinking of what may cause pus formation in surgical wounds, he experimented with rags and phenol and used it as wound dressings. Sure enough, his patients did not develop gangrene after being dressed with carbolic acid or phenol treated rags. Later on, he improved on excluding bacteria from his operating suite by incorporation of clean environment as a prerequisite in aseptic surgery (Lister, 1909). See more: how to write an academic introduction In modern days, Lister’s work on antiseptic surgery had decreased much of the deaths caused by hospital-acquired infections brought about by practicing of good science (Pasteur and Lister, 1996). By applying his notion of the germ theory via his promotion of environmental cleanliness and sanitation, he inculcated the modern medical practitioners with standards of disease prevention that ultimately lead to reduction of major infections like tuberculosis (Osborn, 1986). Most notably, in his honor, Listerine ® was named after him. In recognition of his efforts, the British Medical Journal recently stated that â€Å"he saved more lives by the introduction of this system than all the wars of the 19th century together had sacrificed† (Nester et al., 2007). To conclude that Lister was more prolific than Jenner, the Jenner Institute of Preventive Medicine in Britain was changed to its current name, the Lister Institute of Preventive Medicine (The Lister Institute). Another notable scientist is in the persona of Dr. John Snow. John Snow, in 1849 published his works entitled, â€Å"On the mode of communication of cholera.† In his research, Snow began to hypothesize that cholera was indeed transmitted by a common source, and sure enough he pin pointed it to a contaminated water pump in Broad Street (Thrusfield, 22007). Though highly criticized and much of his researches were dismissed, he never did falter in seeking out the truth. Despite of these obstacles, he never faltered to show the good qualities of an epidemiologist: good record keeper, determined, dedicated and highly skilled (Stanwell-Smith, 2002). A good record keeper, he was a very keen observer and he never did forgot to take into accounts this minute details that allowed him to solve the mystery of the cholera epidemic in London. Moreover, determined and dedicated to his work even though criticisms were all around him and yet a highly skilled scientist never did show attitudes that will hinder him from succeeding (Prescott et al., 2005). His works have led people to dub him as â€Å"the father of epidemiology.† Sure enough, epidemiology and public health cannot have gone a million step without the initiative of the medical doctor who was once criticized for hypothesizing something at that time which cannot be proven until later years where, the bacteria responsible for the disease was isolated. It may be another story of another scientist, but without Snow, nothing not even the prevention and determination of the occurrence of diseases can progress (Stanwell-Smith, 2002). Sure enough, Jenner may have helped in improving disease prevention by first creating the vaccine and subsequent studies leading to its development, it cannot be disclosed that Lister and Snow, did more achievements in the field of microbiology and public health per se. It may be fitting to say that Jenner may be a great microbiologist, it is only proper to also uphold and acknowledge other note taking efforts of these other microbiologists. Part B. In the summer of 1999, the first human case of West Nile Encephalitis in the western hemisphere was documented. By the end 0f 2002, the WNV epidemic have resulted to at least a total 4,156 human cases (with 2,943 meningoencephalitis case and 284 deaths), 16,741 dead birds, 6,604 infected mosquitoes and 14,571 equine cases. This epidemic was the largest recognized arboviral meningoencephalitis epidemic in the Western Hemisphere (CDC, 2003). The Virus Western equine encephalitis is a member of the Genus Flavivirus under the Family Flaviviridae (Tortora et al., 2007). The virions are spherical and around 50 nm in diameter. It is widely distributed throughout the Americas, especially after the onset of the epidemics in 2002. It is maintained in an endemic cycle involving domestic and passerine birds and Culex sp. serving as the vector host (Murphy et al., 1999 ).   WNV infection in humans produces either asymptomatic infection or mild febrile disease, sometimes accompanied by rash, which should be differentiated from dengue hemorrhagic fever. The human case-fatality rate in the U.S. has  been 7% overall with 10% of patients having neuroinvasive WNV disease (CDC, 2003). The Outbreak Although unknown how or when WNV was introduced into North America, international travel of infected people, importation of infected birds or mosquitoes or migration of infected birds are all possibilities and cannot be ruled out. Overwintering mosquitoes during the winter of 1999 to 2000 have been the mode wherein the virus has propagated throughout New York. It has then undergone several cycles of overwintering and by the end of 2002 has affected 44 states, including the District of Columbia. It has now been proven that the mosquito carry the virus and have traveled initially from New York to nearby states infecting other animals, most notably humans. (CDC, 2003). Control and Prevention Prevention and control of WNV encephalitis was accomplished effectively through a series of comprehensive efforts and programs including integrated pest management. It should be taken into consideration that the priority prevention for this type of disease is destruction of mosquito habitats which serve as the main vector. Likewise, sanitation and water management greatly reduced the total number of cases from that of 2002 to a tolerable one. (CDC, 2003)

Pleaes .Requires.Overview.Paraphrase..Correct grammar - Essay Example (Pauline and Young 1984, 30) Research methodology is crucial to this research, since it assists the researcher to identify the issues and variables that are supposed to determine and the result as well as the conclusion of this study. Meanwhile it also helps the researcher to envisage how the issues and variables may bring about changes in the impacts (Weinberger 2007). In this research paper, the researcher has attempted to employ a mixed method –a term that refers to the use of both the quantitative and qualitative research tools and measures in order to draw consequential conclusions depending on the findings. Indeed a qualitative-quantitative research method focuses on an integrated data collection and analyzing system that inquires into both questionnaire and interview data and analyzes them in a single study or in multiple studies. (Cresswell et al 2002, 3) In this paper an integrated research method will be employed to collect data, through both questionnaires and inter views, which are related to maintenance and design factor and to combine, compare and analyze those data using the qualitative-quantitative research tools in the analysis chapter of this paper. ... tial since it enables both the researcher and the readers to focus on the aim of the paper, to guide themselves to the end of the paper and at the same time, to provide the readers with the scope to think on the declared aims on their own alongside the progress of the research. (Phillips and Phillips 2008) This research paper primarily focused on collecting data that are related to design and maintenance defects as well as their impacts on the maintenance and management of hospital buildings in Saudi Arabia. Secondarily, it explores the concerning roles, responsibilities, obligations, and liabilities of the agents who are involved in the design and maintenance performance. Last but not the least, the project’s humanistic aim was to make the people related to the Hospital building’s design and maintenance aware of the drawbacks and defects and to enable them to play significant roles in the economic and social well-being of Saudi Arabia through encouraging reform and imp rovement in the design and maintenance protocols associated with hospital buildings in the region. RESEARCH METHODOLOGY PLAN The areas that this research projected had targeted to focus on were of two different qualities. The maintenance area of this research project involves people’s, perception of the convenience of the building, who used the buildings more or less frequently. Therefore data for this area were collected and analyzed through the qualitative research method. Again due to the technical nature of the design defects, the data in this area will be collected and analyzed through quantitative method. Indeed both of the two research methods have merits and demerits. In the following discussion, the research methods’ advantages, reliability, validity and limitations will be discussed

Project Mgmt Essay Example | Topics and Well Written Essays - 500 words

Project Mgmt - Essay Example having at least one member of senior management represented on a steering committee (Englund & Bucero, p.88) that meets periodically to review the direction, milestones, progress, and costs of the project. A concise summary should be presented periodically to the steering committee with a clear outline of any expectations from senior management. Another way is to agree on a project sponsor within the client organization who champions the cause of the project and liaises with all stakeholders. The sponsor is then given the responsibility to maintain the â€Å"upper management link† for the project (Englund & Bucero, p.10). Underlining this involvement is continued communication while taking care that problems that could be resolved at a lower level are not escalated to the steering committee or the senior management (Lester, 2007, p. 87). Clear statement of requirements: A clear definition of requirements for the project determines the planning and direction of the entire project. Requirements must be discussed and defined thoroughly and documented in a Requirements Specification Document. This is directly linked with the list of deliverables which then sets the direction the project will take (Cleland & Ireland, 2007, p. 271). It is also essential to keep in place change control procedures as some requirements may change over time and must again be clearly stated and incorporated into the project plan if accepted (Cleland & Ireland, 2007, p. 271). Accurate documentation of requirements results from interviews and discussions and must be signed off by all stakeholders reflecting the agreement on their clarity, accuracy, assumptions, and correlation with the deliverables. An engineer at Morton Thiokol suspected that the O-rings in the space shuttle Challenger’s solid rocket boosters were faulty and would not work at low temperatures below the threshold of 53 degrees. On the ill fated day of the disaster, the temperatures were expected to be 10 degrees below
