A new literary programme has been started in the West AfricanService of the B.B.C., and this article is a reprint of oneof the talks. The Ibo speaker was formerly in the Customs, andqualified as a barrister last November: he is also the authorof numerous poems in English, and of a novel, The Prince ofUtete. The other two are schoolmasters working as Assistantsat the School of Oriental and African Studies. For technicalreasons, the orthography is not quite complete.  相似文献

This article assesses the effects of one jurisdiction's attempt to control its lockup population through creation of a separate processing center designed to expedite initial processing of individuals charged with misdemeanors and minor felonies. In the new center, cases were screened and initial hearings held around-the-clock, seven days per week. “Before” and “after” samples of arrestees are compared on prosecutorial screening time, time to court, and time in custody. The results show significant reductions in case screening and length of time to initial court hearing. Individuals released on recognizance and those with no charges filed spent significantly less time in custody and saved considerable bed space for the jurisdiction. Individuals with bond set experienced no reductions in length of custody. Collateral consequences of the new facility included improved procedural justice, expanded detention capacity in the county, and an end to part of the federal litigation.  相似文献

In this article we explore how much state is necessary to make governance work. We begin by clarifying concepts of governance and the “shadow of hierarchy” and we follow this clarification with a brief overview of empirical findings on governance research in developed countries. We then discuss the dilemmas for governance in areas of limited statehood, where political institutions are too weak to hierarchically adopt and enforce collectively binding rules. While prospects for effective policymaking appear to be rather bleak in these areas, we argue that governance research has consistently overlooked the existence of functional equivalents to the shadow of hierarchy. We assert that governance with(out) government can work even in the absence of a strong shadow of hierarchy, we identify functional equivalents to the shadow of hierarchy, and we discuss to what extent they can help overcome issues of legitimacy and effectiveness in areas of limited statehood.  相似文献

In this article a practical case is described when gunshot directions and position of a victim's body at the moment of each shot were determined by natural simulation using an LG-78 laser (made in the form of a gun).  相似文献

A mock jury study was conducted to test the hypothesis that perceptions of a witness can be biased by presumptuous cross-examination questions. A total of 105 subjects read a rape trial in which the cross-examiner asked a question that implied something negative about the reputation of either the victim or an expert. Within each condition, the question was met with either a denial, an admission, or an objection from the witness's attorney. Results indicated that although ratings of the victim's credibility were not affected by the presumptuous question, the expert's credibility was significantly diminished—even when the question had elicited a denial or a sustained objection. Conceptual and practical implications of these findings are discussed.This research was supported by funds provided to the first author by the Bronfman Science Center.  相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.  相似文献

An important national initiative in juvenile justice is Juvenile Offender Reentry (JOR). The renewed emphasis on offender reintegration has generated significant attention to juvenile justice practices, with the notable exception of juvenile confinement facilities. Juvenile detention and, to a lesser degree, juvenile corrections practitioners are involved but not invested in reentry, having made very few programmatic changes to accommodate JOR initiatives largely because these initiatives have been external to the institution and its staff. Yet, reentry is a powerful concept for juvenile facility practitioners, and the application of reentry principles could have a profound impact on daily operations. This article addresses a range of issues about investing juvenile institutions in reentry practices. Several reentry models are discussed along with their implications for daily operations and programs.  相似文献
