PCR amplification of tetrameric short tandem repeats (STRs) can lead to Taq enzyme slippage and artefact products typically one repeat unit less in size than the parent STR. These back stutter or n ? 4 amplification products are low-level relative to the amplification of the parent STR but are widely seen in the forensic community where tetrameric STRs are employed in the generation of DNA profiles. To aid the interpretation of DNA mixtures where minor contributor(s) might be present in comparable amounts to the back stutter products, the typical amounts of back stutter generated have been well characterised and guidelines for interpretation are in place. However, further artefacts thought to be Taq enzyme slippage leading to products with one repeat unit greater than the parent sequence (n + 4 or forward stutter) or two repeats less (n ? 8 or double back stutter) also occur, but these have not been well characterised despite their potential influence in mixture interpretations. Here we present findings with respect to these additional artefacts from a study of 10,000 alleles and include guidelines for interpretation.  相似文献

This article asks the following questions. Which terrorism threats, challenges and responses did key players consider to have been decisively changed by 9/11? On close inspection now, nearly two decades after those attacks, how are we to assess such claims? What did 9/11 really change regarding terrorism and counterterrorism? And what remained unaltered? The article’s central argument is this: some western states exaggerated the extent to which terrorist threats and challenges had been changed by 9/11 and, as a consequence, they did significantly alter some of their responses to terrorism; but at the heart of this ironic process was the tragic reality that, had there been a more serious-minded and historically sensitive recognition of how little had necessarily been changed by 9/11 in terms of terrorist threats and challenges, then the twenty-first-century experience of non-state terrorism would have been much less painful than has been the case in practice.  相似文献

This paper examines a political struggle in the Australian federal sphere over parliament's right, exercised through the Office of the Auditor-General, to oversee the accounts and management practices of the executive and entities created by legislation to deliver public services. The period from the early 1970s witnessed a dramatic shift in the method of delivering government services to the community and an increasing attention to economy, efficiency and effectiveness in their administration and delivery. The Australian government has increasingly used private sector organisational models and modern management and accounting practices to deliver a wide range of services. The rise of these 'new public management' practices resulted in an erosion of traditional parliamentary oversight of government management and reporting activities. This historical analysis is based upon Porter's (1981) processual analytical framework. The analysis focuses on the action of groups such as the executive, parliamentary committees and the Office of the Auditor-General as evidenced in documents produced in response to critical events. Models developed by Funnell and Cooper (1998) are used to characterise the transition of public sector audit from a traditional administrative model to a corporatist model.  相似文献

Expressive suppression is regarded as a generally ineffective emotion regulation strategy and appears to be associated with the development of depressive symptoms among adolescents. However, the mechanisms linking suppression to depressive symptoms are not well understood. The main aim of this study was to examine two potential mediators of the prospective relationship from depressive symptoms to expressive suppression among adolescents: parental support and peer victimization. Structural equation modelling was used to construct a three-wave cross-lagged model (n?=?2,051 adolescents, 48.5?% female, at baseline; 1,465 with data at all three time points) with all possible longitudinal linkages. Depressive symptoms preceded decreases in perceived parental support 1?year later. Decreases in parental support mediated the relationship between depressive symptoms and increases in expressive suppression over a 2-year period. Multi-group analyses show that the mediation model tested was significant for girls, but not for boys. No evidence for other mediating models was found. Although initial suppression preceded increases in depressive symptoms 1?year later, we did not find any evidence for the reversed link from suppression to depressive symptoms. Clear evidence for a reciprocal relationship between depressive symptoms and parental support was found. However, only limited and inconsistent support was found for a reciprocal relationship between depressive symptoms and peer victimization. Finally, although some evidence for a unidirectional relationship from parental support to increases in suppression was found, no significant prospective relationship was found between peer victimization and suppression. The implications of our clear results for parental support, and mostly lacking results for peer victimization, are discussed.  相似文献

A decade after the United Nations conferences on gender equality and social development, this paper explores their policy origins and discusses their differential impact on international aid since 1995. The author draws on her direct experience to consider why Copenhagen led to Poverty Reduction Strategies and the first Millennium Development Goal, whereas Beijing has become largely invisible in the mainstream world of aid. She argues that the powerful influence of economic rational choice theory associated with bureaucratic modes of thought has meant that the central debate in development policy has remained that of growth versus equity. Beijing's agenda of societal transformation offered another paradigm of development that has remained marginal. The paper concludes with a proposal. If international aid policy could handle more than one paradigm and thus be more open to different ways of thinking about economy, society and politics, aid agencies would be better able to support transformative processes for social justice.  相似文献

The purpose of this study was to extend work seeking to improve research definitions of chronic maltreatment by contrasting a definition based on patterns of CPS reports across childhood developmental stages to a previously used definition based upon duration of the period including reports, using teacher-estimated peer relations to represent an extrafamilial outcome domain of social adaptation. The sample includes 387 children who are participating in a multi-site longitudinal study and had been reported for abuse or neglect to CPS between birth and age 8. CPS records from this time period provided the basis of two chronicity constructs: 1) an ordinal categories (OC) definition based upon four Eriksonian stages, and 2) a durational definition (time between first and last reports). Block-wise regression analyses were conducted to examine the relative degree to which the two chronicity definitions contributed to prediction of teacher-estimated peer relations at the age 8 interview. Chronicity characterized with reference to developmental stages significantly predicted troubled peer relations, with child age, sex, and minority status, family income, geographic location, and time of first report taken into account. The effect was pronounced with regard to aggressive peer relations. Duration of maltreatment reports also predicted aggressive peer relations, but significantly less so than did the OC definition. The findings support the view that maltreatment chronicity is usefully defined by taking children’s development into consideration to characterize patterns of maltreatment across developmental stages. Practice and research implications are suggested.  相似文献
