Conventional methods for the identification of different body fluids like blood, semen and saliva from biological stains involve immunological or enzymatic detection of certain proteins. In this study, we investigated potential RNA markers with the aim of developing Real-Time polymerase chain reaction (PCR) based methods to allow differentiation between several body fluids. Total RNA samples from artificially stained swabs and from various pieces of evidence from case work were extracted, amplified and analyzed with several RNA markers. Three assays detecting the body fluids of interest were selected: hemoglobin-alpha locus 1 (HBA), kallikrein 3 (KLK) and mucin 4 (MUC). With this approach, we demonstrate that specific Real-Time PCR assays are useful in identifying the source of the biological stain. Furthermore, RNA profiling of various body fluids was even possible on samples stored over a long period of time at ambient temperature. The stability and sensitivity of the applied method outlines a novel application for Real-Time PCR within the forensic field.  相似文献

This paper combines two recent developments in just world research: the conception of belief in a just world (BJW) as a resource for coping and well-being in everyday life, and the distinction between two different facets of BJW, namely belief in immanent justice (BIJ) and belief in ultimate justice (BUJ). Moreover, these two aspects are adapted to the school context and educational psychology. Scales for measuring ultimate and immanent justice in schools were developed within a German pilot reform project with a sample of 1274 pupils. The two facets could be distinguished by means of factor analysis. The reliability of the two scales is satisfactory, and their validity is confirmed by their differential correlational patterns. Results show that not every form of BJW automatically functions as a coping resource. In fact, only BUJ is able to protect pupils' mental well-being, whereas immanent justice can actually jeopardize well-being. Similarly, BUJ is associated with the perception of solidarity and learning enjoyment in class, whereas BIJ is more closely associated with the experience of rivalry and competition in class. Finally, the socialization of the two justice beliefs is considered. The cross-sectional data provide some evidence to suggest that friendly and supportive parenting styles can promote BUJ, whereas strict parenting styles may further BIJ. More longitudinal research is needed to obtain further insights into these phenomena.  相似文献

Relying on rarely analyzed public opinion data from the 1930s and early 1940s, we take issue with the notion popular in contemporary liberal circles that the New Deal era represented a period of expansive commitment to the security and well-being of the poor and politically disenfranchised. At least where the public is concerned—as opposed to the progressive policy makers in the Roosevelt administration—the jobless were regarded with suspicion, immigrants should be forced to “go home,” women belong in the kitchen not on the shop floor. The harsher the economic conditions (by state), the more conservative were the public attitudes. Hence New Deal legislative victories accrued despite rather than because of public support.

The paper assesses the influence of electoral rules on vote choice and election outcomes using a quasi-experiment conducted during a recent Canadian provincial election. Respondents were invited to vote under three voting systems (first past the post, alternative voting and proportional representation) and to answer a short questionnaire. We examine how the distribution of votes and seats is affected, and we ascertain how much of the total difference is due to psychological and mechanical effects. We find that a PR system would have increased legislative fractionalization by the equivalent of one effective party and that the mechanical effect is much more important than the psychological effect. As for AV, its mechanical and psychological effects act in opposite directions.  相似文献

This article argues that Spain has been the driving external force in the advancement of LGBT rights in Latin America, from marriage in Argentina to the regional recognition of “sexual diversity rights” as human rights. Acting as “norm entrepreneurs,” Spanish activists and organizations, relying on development aid, have promoted their perspectives through two approaches: strategic consulting and resource transfer. Their diffusion is illustrated primarily by the Argentine case. There, activists underwritten by Spanish resources have borrowed Spanish strategies to achieve “the same rights with the same names.” Besides broadening our understanding of the struggle for LGBT equality in Latin America, this article deepens the explanation of norm diffusion, focusing on emergence. In this stage, specific individuals and organizations deliberately select appropriate “targets” for and moments of intervention. But norm “receptors” must also be ready for action.  相似文献
