The terms Attention Deficit Disorder (ADD) or Attention Deficit/Hyperactivity Disorder (AD/HD) refer to a neurological impairment that affects the individual's ability to sustain attention and to behave in a calm, rational manner. 3 Although this disorder has long been considered to be restricted to childhood, recent research has demonstrated that many children carry it over into adult life and take it with them into the workplace. Most U.S. courts have treated AD/HD as a disability covered by the Americans with Disabilities Act (ADA). 4 However, in the summer of 1999, the U.S. Supreme Court made three decisions that will undoubtedly affect the future status of AD/HD and other impairments under the ADA. This article examines those decisions, how they affect the employment rights of AD/HD-afflicted employees, and the changes they will probably bring to litigation in this area. Because we have many reservations about the court's decisions, we not only voice our criticisms of the decisions, but also offer an alternative approach.  相似文献

The nutritional habits of UK consumers have become a cause for concern with an increasing number of people suffering from diseases related to nutrition. The way in which food is prepared may contribute to the nutritional content of the diet. Traditional methods of cooking and eating are being influenced by increased ownership of domestic appliances. This study aimed to carry out a cross sectional study of people living on Merseyside to determine the ownership and use of small kitchen domestic appliances in relation to the possible consequences the appliances may have on the nutrient intake of the individual. An opportunistic sample of 276 female adults aged 25–70 years was recruited from amongst university staff and community groups within Merseyside. Data were collected using a self‐completion questionnaire consisting of questions concerning personal details, the ownership and use of domestic appliances that may influence nutrient intake. The Liverpool John Moores University Ethics Committee granted ethical approval. Microwave ovens, electric toasters and grills were owned by 80% of the population. Coffee makers, handheld electric food mixers, sandwich makers, blenders and food processors although owned by over 45% were used by the majority only once a week or less. Newer items such as a bread maker were owned by 9% who were significantly more likely to have a professional occupation. Those with unskilled occupations were significantly more likely to own a deep fat fryer and least likely to own a food processor. Those aged 25–34 years were significantly least likely to own a handheld food mixer. Households comprised of couples with or without children were significantly more likely to own sandwich makers, bread makers, food processors and handheld food mixers. No difference in the use of the appliances was found with occupational group or age. A large percentage of people own a variety of domestic appliances, the use of which may have a beneficial effect on their nutrient intake, however, it is of concern that those in the lower socio‐economic group were more likely to own appliances that will have a negative effect on their diet.  相似文献

This work explores how network partners collaborate to innovate and innovate to collaborate and thereby achieve value. The innovation processes analyzed are within an IJV in the Chinese exhibition industry. The findings highlight that the IJV's development of a successful trade show resulted from effective co-innovation by partners which enabled the exploitation of opportunities in an industry characterized by rapid growth and continuing structural change. Partner co-innovation enabled evolving strategic and operational capabilities which has led to continued and growing market success. This co-innovation involved the targeted co-mingling of partner resources which creates value that motivated continued cooperation. The effectiveness of the partners' activities is evidenced by the growing size and prestige of their large-scale trade show as well as the expansion of the IJV into other endeavors. The paper concludes by considering the way these innovative processes can be applied in other contexts.  相似文献

We model the dynamic volatility and correlation structure of electricity futures of the European Energy Exchange index. We use a new multiplicative dynamic conditional correlation (mDCC) model to separate long‐run from short‐run components. We allow for smooth changes in the unconditional volatilities and correlations through a multiplicative component that we estimate nonparametrically. For the short‐run dynamics, we use a GJR‐GARCH model for the conditional variances and augmented DCC models for the conditional correlations. We also introduce exogenous variables to account for congestion and delivery date effects in short‐term conditional variances. We find different correlation dynamics for long‐ and short‐term contracts and the new model achieves higher forecasting performance compared \to a standard DCC model.

McConnell examines problems connected with measuring the readability of introductory economics textbooks and observes that an index of readability based on sentence length and the number of syllables per some given number of words may be deficient, misleading, and possibly counterproductive. In this connection, he observes that “virtually no work has been undertaken to determine whether the choice of textbook is a significant factor in determining student understanding and performance.” Research in this area might make it possible to substitute empirical evidence for what most instructors in their selection of a textbook attempt to intuit.  相似文献

Technology application in retailing has a considerable history, with applications for the most part aimed at labour cost reduction. The technologies now being applied in retailing and distribution however differ from these earlier ones in a fundamental way. The new technologies in micro‐electronic based computing and micro‐electronic communications differ by being general purpose and flexible and by developing very rapidly. The new technology is enabling changes to take place in the distribution channel. The areas of applications of the new technology and the applications and reasons of technology introduction are analysed in this paper.  相似文献

Corporations have been investing in academia to an extent that could be classified as a corporate takeover of universities. Intra‐university critics see this as an ethical problem, because of the degree of business control over university policies and decisions which accompanies the funding. University critics rarely suggest that the corporate funding be given up, returned, or even limited. What they protest against is corporate control, which they see as threatening university autonomy, and as inimical to the public good. Multi‐university conferences have been held focusing on this problem, and the most serious solution proposed thus far is to construct a relevant code of ethics regulating and limiting corporate involvement, through standards and guidelines which corporations will then have to subscribe to, in order to fund universities. However, there is a conflict of interest here. Universities have a public trust and a fiduciary duty not to compromise education. This implies a covenant not to cede power to outside interests, not to use university resources, or faculty and students, as a means to an educationally irrelevant end. Universities cannot sell out. However, it seems equally dishonest not to offer their students a well‐funded first‐rate, quality education in applied fields with current skills, maximum research opportunity, and the corporate ties that would allow them to obtain jobs. We examine three cases showing errors made by universities in ceding control to corporate investment, and draw some policy conclusions.  相似文献
