This paper provides rigorous evidence (for 12,130 participants in a series of naturally occurring randomized lotteries) that a large‐scale high school reform initiative (New York City's creation of 100+ small high schools of choice between 2002 and 2008) can markedly and consistently increase high school graduation rates (by 9.5 percentage points overall and for many different student subgroups) for a large population of educationally and economically disadvantaged students of color without increasing annual school operating costs. These findings are directly relevant to current debates by policymakers and practitioners about how to improve the educational prospects of disadvantaged students in the United States. 相似文献

This article uses empirical evidence from rural Tuscany in the 15th century to compare three frameworks for conceptualizing household strategies: Chayanov's analysis of the domestic economy, Bourdieu's treatment of social reproduction, and Weber's distinction between budgetary units and profit-making enterprises. Although Bourdieu's framework did not work well in this context because there was little evidence that peasants employed strategies to prevent the division of land, there was considerable evidence to support Chayanov and Weber. As Chayanov predicted, many households allocated labor according to a tradeoff between providing for family members and avoiding drudgery. The Weberian perspective also worked well because it explained why these smallholders often divided their holdings and used money in their household strategies. 相似文献

There is growing interest in understanding how different research methods are perceived by victims of violence and what survivors will reveal to researchers (termed meta-research or meta-studies). The purpose of this project was to conduct a qualitative meta-study on why rape survivors chose to participate in community-based, face-to-face interviews. Participants mentioned four primary reasons for why they decided to participate in this study: (a) to help other survivors, (b) to help themselves, (c) to support research on rape/sexual assault, and (d) to receive financial compensation. Implications for designing research recruitment protocols are discussed. 相似文献

First-in-Human Trial Participants: Not a Vulnerable Population, but Vulnerable Nonetheless 总被引:1,自引:1,他引:0

The 21st-century translational science campaign could lead to an increase in first-in-human (FIH) trials. As tests of investigational interventions move from the laboratory to human research, scientists, officials, and review committees should address ongoing concerns about the ethics of FIH trials. In this article, I describe three ethical considerations relevant to all FIH trials: (1) the requirement for adequate preclinical research; (2) study design safeguards; and (3) choice of subject population. I also examine specific ethical considerations relevant to the three subject populations (healthy volunteers, seriously ill patients lacking standard treatment options, and stable patients) involved in FIH research. I recommend a variety of actions that could increase subject protection and the value of the information generated in FIH trials. 相似文献

In an effort to examine how higher education institutions have provided women with resources to handle issues that disproportionately
affect them, this study assessed the availability of women’s resource centers on college campuses within the United States,
with a particular focus on sexual assault-related resources. A website content analysis was conducted, through which we coded
to assess ease of use, clarity, and comprehensiveness of the programs and information made available to women. Although many
universities had sexual assault literature, few had women’s resource centers. In addition, the quality of literature and programs
varied greatly among the universities. Future research should attempt to explain organizational differences in college responses
to the call for resources, as well as examine women’s experiences with resources on campus.
Portions of this research were presented at the 2006 meetings of the American Society of Criminology in Los Angeles, CA and
at the 2006 meetings of the Midwest Sociological Society in Omaha, NE.

Under current U.S. law, physicians may prescribe drugs and devices in situations not covered on the label approved by the Food and Drug Administration. Those supporting this system say that requiring FDA approval for off-label uses would unnecessarily impede the delivery of benefits to patients. Patients do benefit from off-label prescribing that is supported by sound scientific and medical evidence. In the absence of such evidence, however, off-label prescribing can expose patients to risky and ineffective treatments. The medical community and federal authorities should more actively promote patients' interests in receiving beneficial off-label treatments. To exercise responsible self-regulation, members of the medical community must determine whether available evidence justifies specific off-label uses and must promote information-gathering when the evidence is inadequate. Physicians should also discuss with patients the uncertainties accompanying off-label uses. Federal authorities should more closely monitor the effects of off-label prescribing and adopt other measures to reduce harm and enhance benefits produced by off-label prescribing. 相似文献

Purpose. The current study examined whether several factors related to the job and demographic profile of police officers are associated with adherence to best‐practice guidelines when interviewing children. Method. One hundred and seventy‐eight police officers completed a standardized (simulated) interview regarding an allegation of abuse by a 5‐year‐old child. Immediately prior to this interview, details were obtained from the officers' regarding their job status, gender, interview experience, the timing and nature of prior training/supervision, and experience outside the policing profession with young children. Results. The results showed that timing of training was the only factor that related to interview performance. The proportion of open‐ended questions among participants who completed their interviewer training course less than 1 month prior to the simulated interview was better than those who completed the training earlier. Interestingly, the performance of the latter group was identical to that of a group of participants who had not yet received any formal interview training. The implications of the findings are discussed, along with directions for future research. 相似文献

This study is concerned with the relationship between witnesses testifying in the Special Court for Sierra Leone and their legal teams. Other research conducted with witnesses in international war crimes tribunals suggests that this relationship has a significant impact on the experience of such witnesses. A structured interview was administered to 171 witnesses who had testified in the Special Court for Sierra Leone. Witnesses generally felt their lawyers' attitude towards them was extremely good. Emotional support and good preparation for testifying seem to be particularly important predictors of witnesses' relationship with their lawyers, as does the level of respect they felt they received from court staff. However, communication between witnesses and their legal teams after the testimony is over did not have a significant impact on witnesses' evaluations of their lawyers' attitude towards them. 相似文献

By analyzing why English local governments have made extensive use of long-term market loans with embedded derivatives, this paper seeks to contribute to the growing literature on local government financialization. Using an original, large-N panel dataset for the period from 1998 to 2014, we show that the configuration of the local political economy is an important driver of financialization processes: a Labour Party majority as well as fiscal and economic stress make it more likely that councils adopt risky financial instruments. As the use of financial innovations has also diffused geographically, policy diffusion impacts local governments as well. Highlighting the conditional effect of finance sector power, which only increases the use of financial innovations in very large councils, as well as the temporal dimension of fiscal and economic stress, we create ample avenues for further research. 相似文献
