In two recent cases, Grutter v. Bollinger, 539 U.S. 306. (2003) and Gratz v. Bollinger, 539 U.S. 244. (2003), the Supreme Court held that the Equal Protection Clause permitted state schools to use race-sensitive admissions in order to obtain the educational benefits that flow from a diverse student body. The diversity-based argument for race-sensitive admissions, scholarships, awards, and other opportunities at universities should have been rejected because it does not consider the full range of costs and benefits and because the more narrow educational effects probably weigh against such programs. However, this does not suggest that applicants’ race, ethnicity, and gender should be ignored. Rather the same consideration that led to the defeat of the diversity argument, i.e., reasoning capacity, supports the consideration of demographic factors. However, attention to such factors further undermines the consequentialist case for affirmative action.  相似文献

The pure sociology perspective invented by Donald Black, a general theoretical framework for the prediction and explanation of social reality, has considerable potential for the scientific understanding of criminal behavior. Several scholars have profitably drawn upon Black’s proposal that a significant amount of crime is a form of disputing or social control, especially to explain violent conflict. However, pure sociology has not yet been extended and applied to criminal behavior more broadly. A pure sociology of predatory behavior, for instance, would address the location and direction in social space of predators, prey, and third parties. In expanding criminological thought, however, pure sociology also challenges it. Pure sociology explanations are not restricted by time or place, a feature not easily realized with a concept so closely tied to a relatively recent social invention: the state. Additionally, the supra-psychological, -anthropocentric, and -teleological nature of pure sociology generates explanations of behavior that are at odds with many of the assumptions of traditional criminology. Ultimately, then, pure sociology yields a new paradigm for the explanation of behavior the state defines as criminal. Presented at the annual meeting of the American Society of Criminology.

In this paper we examine the legal aspects of corporate computer usage policies including their creation, management, and their relevance to corporate computer forensic investigations. Misuse of corporate computing facilities cannot only lead to a reduction in employee productivity and network bandwidth, but can also increase the risk of infection of such facilities by computer viruses and other malicious code. Moreover, it may lead to the risk of liability and legal action.  相似文献

Since the 1990s there has been a long-standing concern in government towards public sector accountability, management, efficiency and service delivery. A number of studies have attempted to analyse the multitude of individual changes and their manifestations through analyses based on a variety of institutional, policy and governmental distinctions. This paper attempts to specify the changes with particular reference to planning, and to consider the evolution of the public service ethic in planning towards more openness, scrutiny, transparency and efficiency with particular reference to the changing ethos of the professional employee. We first explore the  main impacts upon local government, the public service ethic and professional planning as a consequence of the Modernization agenda and freedoms and flexibilities initiative. We then look at how such changes have impacted upon the ethos and values in public service and planning. We draw on some evidence of Ombudsman cases to highlight issues of professional values in planning practice over the past decade before finally drawing these strands together in some conclusions. Our principal findings indicate that the much-trumpeted decline of services and standards may not have been as apparent as is sometimes portrayed and that internal professional attitudes and values towards the external changes may not have significantly altered over the same period.  相似文献

The purpose of this study was to investigate how different types of child maltreatment, independently and collectively, impact a wide range of risk behaviors that fall into three domains: sexual risk behaviors, delinquency, and suicidality. Cumulative classification and Expanded Hierarchical Type (EHT) classification approaches were used to categorize various types of maltreatment. Data were derived from Wave III of the National Longitudinal Study of Adolescent Health (Add Health). Our sample consisted of White, Black, Hispanic, and Asian females ages 18 to 27 (n = 7,576). Experiencing different kinds of maltreatment during childhood led to an extensive range of risk behaviors within the three identified domains. Women experiencing sexual abuse plus other maltreatment types had the poorest outcomes in all three domains. These findings illustrate that it may no longer be appropriate to assume that all types of maltreatment are equivalent in their potential contribution to negative developmental sequelae.  相似文献

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.  相似文献
