Samples, Power Analysis, and Design Sensitivity - Statistics Project Example A research that lacks either form of validity communicates possible deviations from actual properties of the research subjects and can therefore not be relied upon. Both external and internal validities are also susceptible to threats that must be monitored for a desired level of accuracy. The two forms of validities are therefore important in developing confidence in drawn conclusions and made inferences from a research initiative. They are however different in their specific scopes of applicability, and their threats. Internal validity for instance defines a research process’ independence from confounds that may influence observations contrary to the treatment’s causal effects while external validity defines the degree of confidence in inferring research results to a population. Another difference between internal and external validity is their sets of threats. Threats to internal validity such as â€Å"maturation,† â€Å"selection,† â€Å"instrumentati on,† â€Å"statistical regression,† and â€Å"attrition† induces bias on the causal effect relationship to impair accuracy of observation on treatment effect. Threats to external validity however include â€Å"reactive effects of testing,† â€Å"interactive effect of selection,† â€Å"reactive effect of innovation† and â€Å"multiple program interface† and induces barriers between properties of the used sample and other population segments (Fink, 2004, 78, 79). Research questions to which external validity is of primary concern are those questions that seek to establish relationships that are generally applicable to an entire population. Example is a research question to establish the relationship between gender and students performance in sciences that is psychologically hypothesized to be uniform across populations. Internal validity, however, is primary to research questions that seek to establish existence of a relationship between two

Managing strategic change Sainbury - Essay Example The threat for Sainsbury was that the removal of physical barriers to trade and the new-found freedom of movement around the European market have served to catalyse European expansion and in so doing raise the degree of European trade. To respond to new environment, the company introduced changes in management style which was brought by new executive. The new style of leadership was â€Å"more consensual, less hierarchical – but not in strategy or in corporate beliefs about the company’s place in the market† (Owen, 2003). Another innovation made by Sainsbury was reorganization and restructuring aiming â€Å"to feature only supermarkets and convenience stores, with Central and Savacentre outlets joining the main estate† (Sainsbury's makes first ever loss, 2004). In spite of planned actions, these changes failed because of inability of staff to manage change and lack of resources to adapt organization to the changes. It is possible to say that the strategy was ineffective for world’s integration and for this reason it failed at the stage of implementation. Specification in Sainsbury was determined as a result of an organization's pol ¬icy, which in turn resulted from decisions on its market policy, which in turn resulted from its consideration of the market or customer needs, requirements, and the activ-ities of competitors. The main mistake was an attempt to reorganize and restructure several organizational levels at the same time.

Legal Issues - Medical Essay Example | Topics and Well Written Essays - 500 words

Legal Issues - Medical - Essay Example A healthcare provider is considered a covered entity. The health care providers shall include the following only: doctors, clinics, psychologists, dentists, chiropractors, nursing homes, and families† (HHS.gov). Thus, in this given problem, Doctor Williams is considered to be included in the list of covered entity, due to the fact that he is a doctor of medicine who disclosed the medical report of his former patient. In the case at bar, it is clear that Dr. Williams committed a medical practice during the abortion services done to one of his patients, Joan. For fear of being sued for medical malpractice, he asked his friend’s advice by showing the medical records of his patient, who told him to talk to a medical malpractice insurer to help him overcome this problem. The act of divulging a patient’s medical record is contrary of the provisions of the HIPAA which provides: â€Å"The Privacy Rule protects all  "individually identifiable health information"  held or transmitted by a covered entity or its business associate, in any form or media, whether electronic, paper, or oral. Therefore, undoubtedly, it can be concluded that Dr. Williams committed a violation of the HIPAA. Here, there was no showing that he requested for permission from his patient to allow him to disclose the PHI. Instead, he used the information as a defense to a potential suit for medical malpractice. By giving out the information to the medical insurance carrier to, he can save himself from help him from any criminal liability for the error committed against patient for the mistake he committed. Since the doctor has identifiable health information, he may face a â€Å"criminal penalty of up to $50,000 and up to one-year imprisonment.   The criminal penalties increase to $100,000 and up to five years imprisonment if the wrongful conduct involves false pretenses, and to $250,000 and up to 10 years imprisonment if the

It is a city with the most diverse ethnic groups, consisting of Whites, Asians, Blacks, Brown (mixed people) and the Amerindian people (CIA World Fact Book 1). 4. Location E shows a sparsely and less populated area within Brazil, depicting the unevenness of the population distribution in the country. The primary factors contributing to the uneven distribution of people in the area is the high rural to urban migration that has resulted to high populations in the cities and he unfavourable climatic conditions. Most people have been moving to cities to look for employment and better living standards. As a result, the rural areas have been left without people. Most rural parts of Brazil experience high temperatures that go beyond 25Â °C. This causes frequent droughts, which have attributed to the migration of people to other regions in search of better living standards (CIA World Fact Book 1). 6.

Trade Mark Case Study Example | Topics and Well Written Essays - 5000 words

Trade Mark - Case Study Example Second life. This scenario discusses whether the following trademark owned by Georgio currently registered as a Class 15 trademark for the past decade can be protected from infringement and potentially "passing off" by Donald and Bernard and /or Trade Mark Infringement under section 10 of the Trade Marks Act 1994. It is stated in the question that Georgio has traded under this trademark as world renowned producer of the finest musical instruments in the world and is currently a favourite brand with the high and mighty of tinsel town and it is also stated that his trademark is used to convey luxury. Therefore the question has been divided into two scenarios: A&B. I have been asked to advise Georgio as to the likelihood of the actions of Barnard being construed under the law as trademark infringement as he has launched an advertising campaign on billboards aiming to sell expensive chocolate by depicting a 'Georgio' piano dripping with liquid chocolate and in which the logo is clearly visible.The Question would also like me to consider the legalities of such a scenario in the virtual world like second life. In this part of the question I have been ... The theoretical premise of Property rights and trademarks An understanding of the philosophical premises behind Property rights are necessary in the understanding of the tug of war between the owners and the users of intangible information.1 Legal Commentators have often expressed their doubts as to whether these rights are actually rights or privileges as Machlup and Penrose have noted:2 " ... those who started to use the word property in connection with inventions had a very definite purpose in mind they wanted to substitute a word with a respectable connotation, 'property', for a word that had an unpleasant ring, 'privilege'." Intellectual property as a "property" thus is an intangible category of property with boundaries that are not always clear cut and which must be actively defended by the holder against infringements. 3 Tangible property is however visible and documented, and the boundaries are more easily given than for intellectual property.4The law has developed to protect a person who holds certain intellectual property will be able to defend this property only if he/she is granted a particular right over this property. For example in relation to patents the rights are defined by the patent authorities based on what is defined in the patent claims.Like other property (tangible) one has to pay certain fees in order to have their "intellectual" property claim examined and determined and also of continuance fees paid.5 The concept of property rights thus stems from the ideas of John Locke.6Furthermore the notions of property rights developed in the 18th century as one of the core civil rights parallel to-and mutually reinforcing-the right to liberty.7However, most

Code of Ethics Paper Essay Example | Topics and Well Written Essays - 1000 words

Code of Ethics Paper - Essay Example Doctors quiet often come across with difficult situations in which they were confused of whether to inform the patient about his/her critical conditions or not. Most of the patients may develop more stress and their condition may become too bad if they came to know that their diseases are incurable and their remaining time in the earth is limited. This often prevents the doctors from informing them about their exact conditions. But as per medical ethics a patient has every right to know about his medical condition even if it is worst or good. Moreover he/she has the right to know more about his health conditions and to accept or reject treatments. In short, autonomy of the patients in accepting or rejecting treatments often been raises many ethical questions. This paper briefly analyses the feasibility of enforcing autonomy of patients in accepting or rejecting treatments in healthcare sector. Autonomy of patients and ethical theories As per the Utilitarian theory of ethics, the mora l validity of an action is determined by the outcome of the action. But as per Kantian ethical theory the purpose of morality is not to make others happy, but to do the right thing just for the sake of doing (Maccarelli, 2006). Utilitarian always assess an activity based on the utility of it. Suppose a patient is experiencing severe pain and the doctors have no hope in saving his life. Under such circumstances the patient may demand mercy killing. If the doctor accepts the patient’s demand, the patient will be benefitted or the utility of mercy killing will be positive for the patient. However, medical ethics ask the healthcare professionals to save the life of the patients rather than taking it. In other words, the doctor will be put into a dilemma when the patient demands mercy killing. But as per medical ethics the autonomy of the patient should be respected. The patient has every right to know about his/her medical condition and the doctor is liable to explain him/her abo ut the present condition and the future prospects. Legally or morally, the doctor don’ have the right to keep the health conditions of the patient as a secret. Keeping the patient optimistic about the recovery when there is no chance is one way of cheating the patient. The patient has trusted the doctor and hence it is morally wrong to give him wrong information about his/her health condition. In short, according to utilitarian ethics, the autonomy of the patient should be given prominence over the professional ethics of the doctor. According to the principles of utilitarianism, cultural, intellectual and spiritual pleasures are of greater value than mere physical pleasure. When we give autonomy to the patients in determining their future, the patients can prepare themselves for accepting the death just like Britain’s famous reality show celebrity Joe Goody did. Joe Goody has celebrated even her death and she has earned lot of money for her kids by selling the outright claim for telecasting her last moments. In short, respecting the autonomy of the patients in taking decisions about their future will bring material benefits also to the patients and the relatives. Kantian ethics also argues in favour of the autonomy of patients. Kant argued that we usually label a parson’s activity as good or evil based on our traditional beliefs and customs rather than
