The authors explored the differences between African American and White college students' drinking behaviors and their attitudes toward consequences, harm-reduction strategies, and health information sources. They collected data from a randomly selected sample of 1,110 students in a large public university to examine the effects of a high-risk drinking prevention intervention. In the current analysis, they compared African American and White students on indicators of high-risk drinking, drinking consequences, harm-reduction strategies, the sources that students typically used for health information, and the believability of those sources. The African American students scored lower on drinking measures than the White students did, reported fewer negative consequences, and more regularly employed drinking-reduction strategies, with one exception--choosing a designated driver. Both African and White respondents reported that their parents were their most frequent and usual sources of health-related information and said that parents and health professionals were the most credible sources. 相似文献

A post-offer screening program jointly developed by the Occupational and Physical Therapy Departments (University of Illinois at Chicago) was first implemented in March 1998. A total of 712 screens were completed from 3-01-98 through 2-28-01. A quasi-experimental design was utilized to analyze changes in Workers' Compensation costs between the three-year period prior to, and the three-year period following program inception. Additionally, injury rates and mean cost per injury were compared between injuries sustained between 3-98 and 3-01 which were incurred by workers who had passed screening and those that had not been screened. Finally, the tabulated cost per screen and reduction in Workers' Compensation costs allowed derivation of a dollar spent/ dollar saved ratio. Dramatic declines in number of injuries, total costs and mean cost per case occurred in the three-year period following program inception. Mean cost per case also dramatically declined comparing injured workers who had passed screening versus those who had never been screened. Cost savings were over US dollars 18 per dollar spent on the program. While a number of mitigating variables may have accounted for some of the profound effects noted, decrease in average cost per case (indicating possible reduction in severity of injury) was consistent with existing literature. 相似文献

Gamma-secretase catalyzes intramembrane proteolysis of the amyloid beta protein precursor, a process closely linked to the development of Alzheimer's disease. This protease also cleaves the transmembrane domain of the Notch receptor as part of a signaling pathway that is essential for proper embryonic development. Recent findings suggest that gamma-secretase is a complex of at least four integral membrane proteins: presenilin, nicastrin, Aph-1, and Pen-2. Assembly of these four components apparently leads to autocleavage of presenilin into two subunits that together compose the intramembranous active site of gamma-secretase. Understanding the mechanism of this unusual enzyme is important, as it is both a key therapeutic target and a founding member of a newly discovered class of intramembrane-cleaving proteases. 相似文献

Despite the prevalence of goal setting in organizations, researchers have not thoroughly examined the implications of goal setting to work outcomes in interdependent work settings. A field survey (n= 442) assessed the relation of goal setting and goal sharing, the extent to which others are aware of an individual's work goal, to performance and conflict across varying levels of task interdependence. The results of moderated regression analyses demonstrate that in highly interdependent tasks, the use of goal setting resulted in lower performance levels. Moreover, goal setting and goal sharing in highly interdependent tasks resulted in individuals' reporting more somatic symptoms. The results are discussed in terms of clarifying the role of goal setting for interdependent tasks. 相似文献

A period of more rigorous strategic management is under way in consumer service businesses. In banking, insurance, lodging, media, retailing, housing, restaurants and education, more growth must come from competitive share shift. This paper b shows the need for a different set of strategies to win in services than have been shaped in the product business context. Specific illustrations show how leading U.S. consumer service companies are building strategic advantage while also improving the value of their business. 相似文献

Public opinion poll data have consistently shown that the proportion of respondents who are willing to have a nuclear power plant in their own community is smaller than the proportion who agree that more nuclear plants should be built in this country. Respondents' judgments of the minimum safe distance from each of eight hazardous facilities confirmed that this finding results from perceived risk gradients that differ by facility (e.g., nuclear vs. natural gas power plants) and social group (e.g., chemical engineers vs. environmentalists) but are relatively stable over time. Ratings of the facilities on thirteen perceived risk dimensions were used to determine whether any of the dimensions could explain the distance data. Because the rank order of the facilities with respect to acceptable distance was very similar to the rank order on a number of the perceived risk dimensions, it is difficult to determine which of the latter is the critical determinant of acceptable distance if, indeed, there is only one. There were, however, a number of reversals of rank order that indicate that the respondents had a differentiated view of technological risk. Finally, data from this and other studies were interpreted as suggesting that perceived lack of any other form of personal control over risk exposure may be an important factor in stimulating public opposition to the siting of hazardous facilities. 相似文献

The assessment of company performance is one of the major dilemmas facing the strategic researcher. This paper reviews the alternative methods available, then uses one approach, peer assessment, to produce a guide to British company performance. Britain's best companies are identified and their profiles are examined. Their declared financial strengths and relative weaknesses in marketing and innovation are identified. 相似文献

Eighteen years of research using the Happiness Measures (HM) is reviewed in relation to the general progress of well-being measurement efforts. The accumulated findings on this remarkably quick instrument, show good reliability, exceptional stability, and a record of convergent, construct, and discriminative validity unparalleled in the field. Because of this, the HM is offered as a potential touchstone of measurement consistency in a field which generally lacks it. 相似文献

Conclusions After half a century of growing dominance of the large corporation by non-owning managers, the 1980s were marked by a slowing or even reversing of their quiet revolution. Professional managers had come to control the corporation on the premise that they could more efficiently produce shareholder value than the original founder-owners. They turned shareholding into a passive investment on the same premise. As companies faced increasingly competitive pressures during the 1980s, however, the legitimacy of the rule of incumbent management came under challenge. No longer could government interference be blamed for many of the problems facing business; fingers pointed at management itself. As the criticism of corporate leadership gathered momentum, a leading diagnosis focused on one of managerial capitalism's crowning achievements: the autonomous power of professional management.The critique viewed the managerial autonomy as excessively permissive, the agency system as no longer effective. Professional managers had come to show too much concern for the social welfare of various stakeholder groups, including themselves, and too little concern for the financial welfare of the only stakeholder group that should really count — the shareholders. Many of the restructuring efforts were thus undertaken in the name of returning companies to the single-minded pursuit of ownership interests. What had stood in the way of such a pursuit was less a matter of government constraint and more a matter of inadequate stockholder vigilance by their appointed agents.Mindful of the critique, incumbent managements moved during the mid- to late-1980s to improve stockholder returns by paring the workforce and cutting other costs. Corporate acquisitions and leveraged buyouts brought new management teams to the fore where others had seemingly fallen short. The resulting restructuring reached a large proportion of the nation's major companies. Half or more of the largest companies had undergone a significant reduction in their workforce. And the dollar value of company resources changing ownership hands expanded considerably. The aggregate purchase price of mergers and acquisitions of publicly-traded firms in 1988 was nearly three times greater than in 1981. Even more striking was the sharp increase in the number of publicly-traded companies and divisions that were taken private. The aggregate dollar value of such buyouts in 1988 had increased almost 25 times over that in 1981. This opening of the market for corporate control among major U.S. firms brought a significant fraction of the nation's large corporations more directly under the immediate oversight of ownership interests.The reassertion of ownership control over large corporations was usually taken in the name of improving corporate earnings. Would be takeover groups generally promised more internal discipline and stronger financial performance. Whatever the actual financial impact of the intensification of ownership interests, available research suggests that it has had organizational impact. General company strategies may come to be more centrally guided while specific operating actions are devolved further down the organization.Ownership change and other restructuring steps have also ramified into corporate social and political action. That outreach is likely to be less vigorous and more divided. It is also being redirected. During the 1970s and early 1980s, corporate energies focused on reducing government regulation and improving community opinion. Those energies are now increasingly focused on facilitating or resisting restructuring. Companies have fought legislation that would limit the process of plant closings, but they have also sought legislation to protect themselves against hostile takeovers.The evidence also suggests that considerable managerial discretion remains in shaping company response to the restructuring pressures. Although market and organizational factors are sure to act as constraints, top management, whether a relatively autonomous non-owning management group or an owner-dominated management, retains an important independent capacity to exercise strategic choice. That choice is likely to receive special shaping by the long-term ascendance of financial managers and the decline of manufacturing personnel at the executive level.Yet corporate change must not be viewed as isolated managerial responses to changing market conditions. Companies and managements frequently look to one another for guidance in coping with ambiguous circumstances. DiMaggio and Powell's analysis of organizational isomorphism, for example, suggests that firms frequently adopt organizational practices not because they are dictated by the firm's market strategies, but rather because they are already used by other companies. Similarly, Granovetter's analysis of the social embeddedness of economic action indicates that company decisions are partially shaped by top management's contacts with their counterparts in other firms. Understanding company responses to restructuring pressures therefore requires a focus on inter-company flows of ideas and doctrines as well as purely internally generated responses specific to the company. Reactions to the restructuring pressures that are collectively developed and defined in the broader business community may prove to be as critical as individually fashioned solutions in guiding management approaches to restructuring during the years to come.
