In 2003, the Supreme Court handed down two landmark decisions regarding the use of affirmative action in higher education. In one case, Grutter v. Bollinger, the Court said it was constitutional to consider race in admissions decisions in order to achieve the educational benefits of a diverse student body. In stark contrast, the Court struck down in Gratz v. Bollinger the University of Michigan's undergraduate admissions policy on the grounds that too much of the decision was based on race. In this research note, we surveyed midwestern and southern institutions of higher education to see how college and university presidents in the Fifth and Sixth federal circuits have sought to implement Gratz and Grutter. We find schools in the Fifth Circuit (southern) do not consider race in admissions decisions and those in the Sixth Circuit (midwestern) utilize race to assemble a student body. We suggest that lower federal court precedent may explain why the midwestern schools consider race but the southern schools do not. 相似文献

Few studies have examined the role of managerial support in the adaptation of entrants to healthcare. The purpose of this study was to identify the job characteristic and role-related variables that mediate the effects of managerial support and personality on the mental and physical health and sickness absence in two independent groups of new recruits to a healthcare organization. Entrants to a healthcare environment (student nurses) were surveyed 25 weeks after entry. Latent variables represented neuroticism, demand, control, role clarity and affective outcome variables in a simplified version of the Michigan model of work stress (House, 1981). This study used a two-stage approach to structural equation modelling, exploring hypothesized structural models on an initial data set (N=195) prior to confirmation on an independent replication data set (N=239) using multi-sample methods. Finally the confirmed model of choice was evaluated using the combined data (N=434). Emotional distress reported at 6 months was found to be associated with dispositional characteristics of the entrant and indirectly, via job satisfaction, with managerial support from academic and clinical sources. Managerial support from academic and clinical sources had an indirect influence on job satisfaction, but by differing mechanisms involving role clarity and control. The demands perceived by the entrants arose from neuroticism and were independent of any other variable. Emotional distress had its deleterious association with sickness absence via somatic health. This study details a series of mechanisms that will subsequently be tested longitudinally. 相似文献

In this first part of the case study the authors introduced the background to the development of the planning models used by the Gulf Company. Both the Linear Programming model and the Sensitivity model are described, with discussion regarding the inter-relationship of these models and the discrete and mutual objectives behind their use. 相似文献

Intergenerational intimacy, social as well as sexual, has been studied in the United States and abroad for some time. In recent years the general trend has been to label such behavior "child sexual abuse." Interest in this type of abuse has generated a considerable amount of more or less scientific literature, some of which seems to have been produced in a "rush to judgment" attempt to build a "professional" literature that supports popular beliefs. This tradition of child-abuse-defined literature, along with the work of investigative and helping agencies which some refer to as a "child abuse industry," has fostered a one-sided, simplistic picture of intergenerational intimacy. A close look at the empirical studies in this tradition reveals flaws associated with two problems: the studies nearly always (1) maintain a narrow focus on sexual contact, and (2) proceed from the related basic assumption that sexual contact in intergenerational relationships by definition constitutes abuse. While sexual abuse certainly occurs, those who apply this assumption to all situations are ignoring empirical findings that show otherwise. Research outside the "child sexual abuse" tradition reveals a broader range of intergenerational relationships outside the family, including a number of aspects which typically are not seen when the focus is on the sexual. Some studies show clearly that even when sexual contact is involved, negative outcomes are not inevitable. This indicates the need for a much broader approach. Further research in North American society and in other cultures would help us to understand more accurately the diversity and possible benefits of intergenerational intimacy. 相似文献

This paper outlines the development of research in the domain of service(s) marketing from its birth as an area of academic study in the 1960s/1970s to the current time. It identifies four phases of development. Phases 1–3 relate to the period before 2004, which focuses on the development of service(s) marketing. In Phase 4, a greater focus on the concept of service (singular) – defined as the application of knowledge and skills – has resulted in developments and directions in service research that offer a different perspective through which to view more general marketing. This different perspective has explicit implications also for wider business and management research. The paper summarizes current research in this domain, which coalesces around three broad perspectives, namely, the service‐dominant logic of marketing, technology and service, and transformative service research. It concludes by outlining likely trends for service research into the future. Three interrelated directions are suggested: research on service in a changing context; research responding to academic schools of thought; and research responding to consumer trends. 相似文献

Although the initial euphoria about Internet‐enabled reverse auctions has given way to a cautious but widespread use of reverse auctions in business‐to‐business (B2B) procurement, there is a limited understanding of the effect of auction design parameters on buyer surplus. In this paper, we study the effect of bidding competition, information asymmetry, reserve price, bid decrement, auction duration, and bidder type on buyer surplus. We collected field data on more than 700 online procurement auctions conducted by a leading auctioneer and involving procurement items worth millions of dollars. Consistent with the predictions of auction theory, the results indicate that bidding competition, reserve price, and information sharing affect buyer surplus. Unlike previous findings in the consumer‐to‐consumer context, we find that bid decrement and auction duration have no effect in B2B procurement auctions. Our results suggest that use of the rank‐bidding format increases buyer surplus when incumbent suppliers participate in the auction. We discuss the theoretical and managerial implications of these findings for future research and for optimal design of online procurement auctions. 相似文献

This paper provides an empirical analysis of the effects of employer‐provided health insurance, Medicare, and Social Security on retirement behavior. Using data from the Health and Retirement Study, we estimate a dynamic programming model of retirement that accounts for both saving and uncertain medical expenses. Our results suggest that Medicare is important for understanding retirement behavior, and that uncertainty and saving are both important for understanding the labor supply responses to Medicare. Half the value placed by a typical worker on his employer‐provided health insurance is the value of reduced medical expense risk. Raising the Medicare eligibility age from 65 to 67 leads individuals to work an additional 0.074 years over ages 60–69. In comparison, eliminating 2 years worth of Social Security benefits increases years of work by 0.076 years. 相似文献

This paper seeks to examine the relationship between smoking bans and the propensity of tobacco firms to engage in foreign direct investment (FDI). Using international business theory based on the firm‐specific advantage/country‐specific advantage (FSA/CSA) matrix, the authors show that, contrary to what one may expect, smoking bans at home are an important institutional intervention, reducing the propensity for firms to engage in FDI, even to countries without a ban themselves. 相似文献
