This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.  相似文献

The public service motivation (PSM) theory has emphasized the distinctive motivational character of public employees in serving public institutions. However, scarce research has explored whether public service motivation extrapolates to civic engagement as another way to participate in public affairs. We contend that public employees' stronger sense of public interest expands toward higher engagement levels in social, economic, political, and civic organizations. Using data from the most recent wave of the World Values Survey from 2017 to 2020 in 77 countries—this study compares the degree of civic engagement of public servants with general citizens' level of engagement. Results across all world regions, except Africa, support the hypotheses that public servants are more willing to participate in civic organizations. However, public employees' civic engagement is contingent on organizational type (modern vs. traditional) and bureaucratic rank (top- vs. street-level), for street-level bureaucrats participate more in traditional but not modern organizations.  相似文献

Aid policy and practice have been thoroughly shaken up over the past few years. One of the reform areas relates to monitoring and evaluation (M&E). In short, aid recipients are asked to elaborate result‐oriented frameworks while donors are expected to harmonise and align their policies and frameworks. This article examines the extent to which joint sector reviews (JSRs) could take the M&E reform agenda forward. JSRs are M&E exercises at the sector level which have the potential to satisfy the M&E needs of various stakeholders while, at the same time, also contributing to the M&E reform agenda. They are increasingly utilised on the ground, yet, so far, there do not exist any systematic stocktakings and/or analyses of them. Our own analysis of a sample of JSRs from the education sectors of Burkina Faso, Mali and Niger indicate that JSRs score highly on harmonisation, coordination, leadership and broad‐based participation, but poorly on alignment. They generally prioritise accountability over learning needs and largely neglect accountability and learning at the level of the sector institutional apparatus. In this article, findings from the field are contrasted with insights from evaluation theory and practice so as to provide suggestions for on the ground JSR improvements.

It is often assumed that political parties have more fluid party platforms than in the past because internal veto players – like party activists – have lost the power to restrain the office-seeking party elite. Several case studies subscribe to this view. However, there is no systematic assessment of this relationship. Using new data this research note investigates this relationship and finds a clear positive effect of leadership domination on party platform change. With leadership domination increasing over time, our model predicts increasing fluidity in party platforms. This note provides a motivational and a numerical argument in favor of this hypothesis, considers alternative hypotheses and provides empirical evidence for the claim using two different datasets.  相似文献

ABSTRACT

Intergovernmental councils (IGCs) are specific, institutionalized forums of intergovernmental relations. They provide essential horizontal and/or vertical executive channels for preparing, deciding, and implementing multilevel policies. We assume there to be variation, both across federal systems and policy domains, in the purpose they serve – from mutual influence and protection of autonomy through joint decision-making to mere exchange of information – the use that central or sub-state actors make of IGCs, as well as their effectivity. In order to map and explain such variation, this introductory article provides a framework for analysis that includes both conceptual building blocks and conjectural relationships, laying the comparative groundwork for the case studies included in this Special Issue. Findings from the case studies indicate that it is primarily the institutional architecture, but also the structure of the multilevel party system, that account for variation in the purpose and effectiveness of IGCs.  相似文献

The article presents the crisis intervention model devised by Andreoli (Geneva) which is currently being developed in most crisis units and emergency services in the French-speaking countries of Europe. Two clinical examples are presented: the Short Therapy Centre (Geneva, Switzerland) and the crisis unit of the Saint-Luc Clinic (Brussels, Belgium). The following aspects of these approaches are discussed: (a) the need for crisis intervention rather than a simple answer to emergency, (b) the need for crisis intervention in all acute psychiatric disorders and not only in psychosocial problems, (c) the need to integrate psychiatric hospitalization into a coherent mental health policy, (d) the need for well-trained and round-the-clock teams, (e) the need for continuity of care.  相似文献

Despite high revalence rates of intimate partner violence in the lives of extremely poor women with depenent children, few studies have investigated the patterns of violence that occur over time, and the characteristics of women that serve as risk markers for partner violence. This study compared 43 adult parricides and 12 adolescent parricides. Several statistically significant differences were observed. Adults suffer from severe mental disorders, have a history of violent behavior and psychiatric antecedents, and are more likely to threaten their parents. Less predictable in their acting out, adolescents present several profiles as a function of victims’ sex, number of victims, diagnostic elements, and being witness to or victim of intrafamilial violence. Results suggest different approaches should be used to understand the dynamics and course of these two groups.  相似文献

Stockholm Syndrome is a paradoxical psychological experience which both intrigues and often frustrates law enforcement and mental health professionals alike. Much attention has been directed toward understanding and defining the contextual variables associated with the development of Stockholm Syndrome. Since it appears that the formation of Stockholm Syndrome may increase the likelihood of hostage survival, discerning the factors that may encourage its occurrence is a priority for crisis negotiators. The purpose of this paper is to (1) analyze crisis situations using actual case examples in which evidence of Stockholm Syndrome has been reported and (2) examine the variables associated with the development of this phenomenon. Case information was obtained from the Hostage Barricade Database System (HOBAS) of the FBI's Crisis Negotiation Unit. Results of this analysis conclude that some, but not all, factors previously hypothesized as requisite to the development of Stockholm Syndrome find additional support from this case analysis.  相似文献
