This article measures the degree to which academic economists have engaged in unethical behavior and the degree to which academic economists believe the profession as a whole engages in unethical behavior. Three main types of unethical behavior are examined: (1) falsification of research; (2) expropriation of graduate student research or including an undeserving co-author on a research paper; and (3) exchange of grades for gifts, money, or sex. Using a unique data set gathered at the 1998 American Economic Association (AEA) meetings, we find that there is a significant amount of misconduct, particularly in the second category.  相似文献

Abstract

The health maintenance organization (HMO) is likely to have a prominent position under national health insurance, which will have a strong systematizing effect on the nation's health services. Over the past two years the University of Massachusetts mental health services have provided benefits at both the university and a private medical group practice. Experience has shown that a university which already provides broad services to a large student population can extend itself to the university community including its faculty and staff. Several advantages of this development, as well as some significant problems, are discussed. As the HMO grew and quality services were established, it became feasible for the private medical group to develop its own mental health component. Based on this and other experiences in mental health delivery systems, certain conclusions are drawn about the ways universities can develop HMOs and some recommendations are made for national mental health planning.  相似文献

Objective: To assess the safety of meningococcal group B (MenB)-4C vaccine. Participants: Undergraduates, dormitory residents, and persons with high-risk medical conditions received the MenB-4C vaccine two-dose series during mass vaccination clinics from 12/2013 through 11/2014. Methods: Adverse events (AEs) were identified by 15 minutes of observation postvaccination, spontaneous reports, surveys, and hospital surveillance. Causality was assessed for serious adverse events (SAEs). Results: 16,974 persons received 31,313 MenB-4C doses. The incidence of syncope during the 15-minutes post-dose 1 was 0.88/1000 persons. 2% of participants spontaneously reported an AE (most common were arm pain and fever). 3 SAEs were suspected of being caused by the vaccine, including one case of anaphylaxis. Conclusions: Most AEs reported were nonserious and consistent with previous clinical trial findings. Measures to prevent injury from syncope and to treat anaphylaxis should be available wherever vaccines are administered. Our safety evaluation supports the use of MenB-4C in response to outbreaks.  相似文献

The Alvey Report has resulted in a growing interest in the UK in ‘expert systems’. It is fairly generally accepted, at least in the UK, that such systems function in a particular type of way, i.e. they arrive at decisions through a process of rule based inference. It is suggested that it may be more fruitful to regard rule based inference as one approach to the construction of expert systems, and that proven techniques of operational research may well be more useful in constructing other types of expert system. Alternative applications of expert systems are derived on the basis of a broader definition of an expert system in terms of what it does rather than how it does it. A parallel is drawn between these applications and some typical concerns of business research. It is suggested that a useful aid in identifying promising business applications of expert systems is to set up four ‘dimensions’ along which different types of system differ. Examples are given of where other techniques might conceivably be useful in applications of expert systems.  相似文献

The Internet has brought, among other things, the online betting exchange. From desks in the City or from laptops on sunny beaches, those in the know or out of it can place bets with each other on anything under the sun, whether likely—Australia beating England at cricket—or the reverse. If you have a hunch that a genetically engineered Tyrannosaur will wander down Oxford Street next year, and if you want to put money on it, Internet betting exchanges will find someone to accommodate you. Leighton Vaughan Williams explains how a simple change in tax regime has brought something other than just a more efficient gambling system. It has created a strangely accurate way of foretelling the future.  相似文献

The placing of a bet is a classic example of decision-making under uncertainty. A betting market is also an example of a simple financial market, but one which possesses the advantage that each bet is characterised by a well-defined end point at which it possesses a definite value, i.e. the amount won or lost. Leighton Vaughan Williams explains the implications for our understanding of economic decision-making of the observed tendency for the expected returns on bets to differ markedly at different odds levels.  相似文献

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients.  相似文献

The examination of dreams should properly be a legitimate topic of sociological investigation. We argue that there are four basic principles of dream-life that suggest that dreams are external to the individual mind and are collective enterprises: 1) dreams are not willed by the individual self; 2) dreams reflect social reality; 3) dreams are public rhetoric; and 4) dreams are collectively interpretable. With the development of sociological approaches that examine topics previously defined as psychological, such as the sociology of emotion and cognition, the seemingly idiosyncratic components of these nocturnal productions should not exclude them from social analysis.  相似文献
