Retrospective review of cervicovaginal (Pap) smears of women with known sexual histories affords an opportunity to assess the potential for postcoital sperm recovery for large numbers of individuals. This study reviewed 542 individuals' Pap smears with accompanying sexual histories. Three hundred forty-nine respondents reported at least one act of sexual intercourse during the five days preceding the Pap smear. Unlike a previous report, the current study showed very poor sperm recovery (maximum of 25% during the first postcoital day). The observed results roughly correlate with the incidence of sperm noted on screening of large numbers of routine clinical Pap smears in a private reference laboratory. Routine Pap smears can detect sperm but do not appear to be an ideal method to substantiate recent sexual intercourse. 相似文献

Explanatory models of malingering strive to understand the primary motivation underlying attempts to feign. Rogers, Sewell, and Goldstein (1994) provided empirical support for the conceptualization of pathogenic, criminological, and adaptational models. In the current study, a prototypical analysis of 221 forensic experts results in a slightly refined formulation: the adaptational model was decomposed into its two broad dimensions (cost–benefit analysis and adversarial setting). An important finding is that the factor structure for the explanatory models remained stable when applied to both forensic and nonforensic cases. As a first investigation, significant differences were observed in prototypical cases of malingering by the category of referral (forensic or nonforensic) and by type of feigning (mental disorders, cognitive impairment, and medical syndromes). Surprisingly, the feigning of medical syndromes appeared to play a relatively prominent role in both forensic and nonforensic cases and to be influenced by the apparent adversarial context of the assessment. Finally, important gender differences were observed, especially with nonforensic prototypical cases of malingering. 相似文献

In this article I draw on public sector reform knowledge in the United States, New Zealand and Australia. I argue that we, as practitioners, do not need to immerse ourselves in academic debates about 'positivism' or 'post-positivism'. These are frameworks for examining knowledge capable of validation. Instead, we are now engaged in using diverse forms of knowledge to spread the word on what works and does not work to deliver outcomes. Such knowledge is not above reproach; it is not acceptable merely because it exists but nor is it unacceptable because it cannot be rigorously validated in a positivist way. 相似文献

What impact can economic incentives have on difficult international security problems, such as nuclear proliferation? This article first discusses theories of the effectiveness of incentives. It then examines the case of the 1994 Agreed Framework accord between the United States and North Korea. It argues that, despite cheating by Pyongyang, the American effort to use incentives in this case was on balance more successful than many now believe, especially in view of the bleak alternatives. If incentives can have an impact in such a "least likely" case, there is reason to believe they could be helpful in resolving other cases of proliferation. 相似文献

A series of side chain regioisomers of 3-methoxy-4-methyl- and 4-methoxy-4-methyl-phenethylamines have mass spectra essentially equivalent to the controlled drug substance 3,4-methylenedioxymethamphetamine (3,4-MDMA), all have molecular weight of 193 and major fragment ions in their electron ionization mass spectra at m/z 58 and 135/136. The acetyl, propionyl and trifluoroacetyl derivatives of the primary and secondary regioisomeric amines were prepared and evaluated in GC–MS studies. The mass spectra for these derivatives were significantly individualized and the resulting unique fragment ions allowed for specific side chain identification. The trifluoroacetyl derivatives provided more fragment ions for molecular individualization among these regioisomeric substances. These trifluoroacetyl derivatives showed excellent resolution on a non-polar stationary phase such as Rtx-1. 相似文献
