A review based on a biased collection of studies is likely to produce biased conclusions. As such, a central component of a quality systematic review is a comprehensive document search. Three issues are explored in this paper that underpin the importance of such a search. First, the evidence of publication selection bias clearly establishes that peer-reviewed journal articles are more likely to show statistically significant results than less formally published studies. Second, the presence of grey literature studies that cannot be discovered through a search of bibliographic databases is demonstrated using Campbell Collaboration systematic reviews, and third, the logical and empirical problems with using publication status as a proxy for methodological quality are examined. More robust methods of identifying research conducted in the social sciences are needed if we are to take seriously the accumulation of knowledge, such as the development of a priori registries of research studies.  相似文献

In its recently published “Smart and Integrated Ticketing Strategy”, the Department for Transport (DfT) set out its vision for a seamless transport ticketing infrastructure across England by 2020, built on smart card ticketing technologies. This article discusses the core aspects of the DfT's strategy, the existing jigsaw of discrete ticketing schemes in the UK, and the challenges of integration. The authors review both legal and commercial risks associated with the procurement of new ticketing infrastructures and outline the key contractual issues to be addressed by operators in smart card ticketing projects.  相似文献

Intellectual property typically involves claims of ownership of types, rather than particulars. In this article I argue that this difference in ontology makes an important moral difference. In particular I argue that there cannot be an intrinsic moral right to own intellectual property. I begin by establishing a necessary condition for the justification of intrinsic moral rights claims, which I call the Rights Justification Principle. Briefly, this holds that if we want to claim that there is an intrinsic moral right to φ, we must be able to show that (a) violating this right would typically result in either a wrongful harm or other significant wrong to the holder of the right, and (b) the wrongful harm or other wrong in question is independent of the existence of the intrinsic right we are trying to justify. I then argue that merely creating a new instance of a type is not the kind of action which can wrongfully harm the creator of that type. Insofar as there do seem to be wrongs involved in copying a published poem or computer program, these wrongs presuppose the existence of an intrinsic right to own intellectual property, and so cannot be used to justify it. I conclude that there cannot be an intrinsic right to own intellectual property.  相似文献

This study examines the features of effective school-based prevention of crime, substance use, dropout/nonattendance, and other conduct problems. It summarizes, using meta-analytic techniques, results from 165 studies of school-based prevention activities that ranged from individual counseling or behavior modification programs through efforts to change the way schools are managed. The results highlight several inadequacies in the existing research for guiding policy and practice, the most notable of which is that many popular school-based prevention approaches have not been well studied to date. The study shows, however, that school-based prevention practices appear to be effective in reducing alcohol and drug use, dropout and nonattendance, and other conduct problems. The size of the average effect for each of the four outcomes was small and there was considerable heterogeneity across studies in the magnitude of effects, even within program type after adjusting for measured method and population differences. Non-cognitive-behavioral counseling, social work, and other therapeutic interventions show consistently negative effects, whereas self-control or social competency promotion instruction that makes use of cognitive-behavioral and behavioral instructional methods show consistently positive effects. Also effective are noninstructional cognitive-behavioral and behavioral methods programs. Environmentally focused interventions appear to be particularly effective for reducing delinquency and drug use.  相似文献

As the architect of racial disparity, racism shapes the vulnerability of communities. Socially vulnerable communities are less resilient in their ability to respond to and recover from natural and human-made disasters compared with resourced communities. This essay argues that racism exposes practices and structures in public administration that, along with the effects of COVID-19, have led to disproportionate infection and death rates of Black people. Using the Centers for Disease Control and Prevention's Social Vulnerability Index, the authors analyze the ways Black bodies occupy the most vulnerable communities, making them bear the brunt of COVID-19's impact. The findings suggest that existing disparities exacerbate COVID-19 outcomes for Black people. Targeted universalism is offered as an administrative framework to meet the needs of all people impacted by COVID-19.  相似文献

Drawing on multiple qualitative case studies of evidence‐based health care conducted in Sweden, Canada, Australia, and the United Kingdom, the authors systematically explore the composition, circulation, and role of codified knowledge deployed in the organizational enactment of evidence‐based practice. The article describes the “chain of codified knowledge,” which reflects the institutionalization of evidence‐based practice as organizational business as usual, and shows that it is dominated by performance standards, policies and procedures, and locally collected (improvement and audit) data. These interconnected forms of “evidence by proxy,” which are informed by research partly or indirectly, enable simplification, selective reinforcement, and contextualization of scientific knowledge. The analysis reveals the dual effects of this codification dynamic on evidence‐based practice and highlights the influence of macro‐level ideological, historical, and technological factors on the composition and circulation of codified knowledge in the organizational enactment of evidence‐based health care in different countries.  相似文献

To award delegates in their presidential primary elections, the US Democratic Party uses Hamilton’s method of apportionment after eliminating any candidates (and their votes) that receive less than 15% of the total votes cast. We illustrate how a remaining candidate may have his or her delegate total decline as a result of other candidates being eliminated; this leads to a new elimination paradox. We relate that paradox to the new states, no show, and population paradoxes and show that divisor methods are not susceptible to the elimination paradox. We conclude with instances in which the elimination paradox may occur in other contexts, including parliamentary systems.
