Institutional development has become a core component of international development programmes. Yet, institutional reforms have, to date, had a disappointing impact on poverty reduction in the South. The causality of the links between institutions and poverty reduction and how exactly the institutional environment and development outcomes affect each other is still unclear. A lack of analytical consensus has resulted in vague policy recommendations and a dearth of clear operational guidelines for international development practitioners. This article provides an overview of the main current institutional development debates and gaps in existing research, and identifies some key organisations working on institutional issues in the academic and practitioner spheres.

Using data from an experimental evaluation of the New Hope project, an anti‐poverty program that increased employment and income, this study examined the effects of New Hope on entry into marriage among never‐married mothers. Among never‐married mothers, New Hope significantly increased rates of marriage. Five years after random assignment, 21 percent of women assigned to the New Hope condition were married, compared to 12 percent of those assigned to the control group. The New Hope impact on marriage was robust to variations in model specification. The program also increased income, wage growth, and goal efficacy among never‐married mothers, and decreased depression. In non‐experimental analyses, income and earnings were associated with higher probability of marriage and material hardship was associated with lower probability of marriage. © 2006 by the Association for Public Policy Analysis and Management  相似文献

This study explored the impact of victim and perpetrator alcohol consumption on police officers' evaluations of an alleged sexual assault and their reported likelihood of charging the perpetrator. Two hundred and twelve police officers were presented with a vignette depicting an acquaintance rape in which the beverage consumption (beer, cola) of both the victim and perpetrator was systematically varied. Results indicated that the officers' perceptions of the complainant's intoxication level, as well as the gender of the officer, influenced officers' evaluations of the alleged sexual assault. The more intoxicated the complainant was perceived to be, the more negatively she was viewed. Female police officers evaluated the victim more favorably than male officers. The only factors related to the officers' likelihood of charging the perpetrator, however, involved their assessment of the complainant's credibility and their perception of the likelihood that the perpetrator would be found guilty in a court of law.  相似文献

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.  相似文献
