In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.  相似文献

Sixteen major evaluations of programs to prevent school bullying, conducted in 11 different countries, are reviewed in detail. Of these 16 evaluations, 8 produced desirable results, 2 produced mixed results, 4 produced small or negligible effects, and 2 produced undesirable results. These varying findings may reflect variations in programs, in implementation, in assessment methods, or in evaluation designs. It is concluded that high-quality evaluations are needed in the future, with randomized designs, theoretically grounded interventions, multiple measures of bullying, and attempts to disentangle the effectiveness of different program components.  相似文献

Toxicologic findings in the USS Iowa disaster.   总被引:5,自引:0,他引:5  
The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims.  相似文献

Veto Players and Civil War Duration   总被引:1,自引:0,他引:1  
Civil wars show a remarkable variation in how long they last. Some end within days; others continue for decades. What explains the extreme intractability of some wars while others are resolved quickly? This article argues that conflicts with multiple actors who must approve a settlement (veto players) are longer because there are fewer acceptable agreements, information asymmetries are more acute, and shifting alliances and incentives to hold out make negotiation more difficult. This veto player approach to explaining variation in civil war duration is tested using a new dataset containing monthly data on all parties to each civil war begun since World War II. The statistical analysis shows a strong correlation between the number of veto players and the duration of civil war.  相似文献

Though many years in the making, the UN Human Rights Norms forCorporations only registered on the radars of most states, corporationsand civil society organisations in August 2003 when they beganto move up the ladder of the United Nation's policy-making processes.Since then they have been subject to intense, and sometimesintemperate, debate, scrutiny and controversy. A particularlegal feature of the deliberations has been the focus on theclosely related questions of the legal standing of the Normsin their present format (namely, an imperfect draft, and therefore,of no direct legal force), and what they might become (possibly—thoughnot likely soon—a treaty that speaks to corporations butbinds states). A potent mix of distrust and suspicion, vestedinterests, politics and economics has given rise to a greatdeal of grand-standing and cant concerning these questions andhow they might be answered. In this article, the authors explorethe history of the Norms and the form and content of the debatethat surrounds them, in their attempt to disentangle the legalfrom the rest. That said, the article also focuses on the realpoliticking of the circumstances in which the Norms now findthemselves and it seeks to offer some guidance as to where theNorms—or at least their substance, if not their form—mightgo from here.  相似文献

Two hundred thirty four adult male inmates entering prison were randomly assigned to an early release program in either a correctional boot camp or a large, traditional prison in the Maryland state correctional system. Boot camp releasees had marginally lower recidivism compared to those released from the traditional prison. A pre-test, post-test self report survey indicated the boot camp program had little impact on criminogenic characteristics except for a lowering of self control. In contrast, inmates in prison became more antisocial, lower in self control, worse in anger management, and reported more criminal tendencies by the end of their time in prison. Criminogenic attitudes and impulses were significantly associated with recidivism. The impact of the boot camp diminished to non-significance when antisocial attitudes or anger management problems were added to the models predicting recidivism. Implications for jurisdictions considering whether to operate correctional boot camps are discussed.  相似文献
