This essay tentatively buttresses Alexander Somek's view that Hermann Heller's 1933 essay, ‘Authoritarian Liberalism’, provides a useful starting point for thinking about the ongoing European crisis, in which European authorities are favouring rigid austerity and pro‐business policies while undermining basic liberal and democratic rights. Heller's unfortunate neglect, especially in Anglophone scholarship, is discussed. Nonetheless, Somek and other recent scholars who have turned to Heller to make sense of the European crisis downplay some of the tough questions raised by any attempt to apply Heller's analysis of the Weimar crisis to the contemporary setting. In particular, Heller's theory relied on a robust social democratic statism which has become increasingly unpopular even among theorists on the political left. 相似文献

This paper reflects on the use of a participatory learning and action (PLA) framework in a strategic planning process (SPP) at a primary school in rural Kenya. Successes and challenges are discussed, focusing on the barriers to fully implementing the PLA framework. Additionally, lessons learnt and ways forward for participatory SPPs are outlined. The PLA framework allowed the project stakeholders to engage in a planning process that gave participants a voice in the process. Although PLA methodology faces shortcomings, the application of this model is a step towards making community development more sustainable. 相似文献

POLICE RESPONSE TO DOMESTIC VIOLENCE: SITUATIONS INVOLVING VETERANS EXHIBITING SIGNS OF MENTAL ILLNESS* 下载免费PDF全文
Drawing on attribution theory, research on police discretion, and public attitudes toward mental illness, we examine attributional processes in police decision making in response to domestic violence situations involving veterans and nonveterans with signs of mental illness. Using data from experimental vignettes varying veteran status, victim injury, and suspect compliance administered to a sample of 309 police officers, the results indicate that 1) veterans are perceived as less responsible for troublesome behavior but more dangerous than nonveterans, 2) suspects’ veteran status has a significant effect on officers’ preference for mental health treatment versus arrest, and 3) part of the effect of veteran status on officer response is mediated by internal and external attributions for problematic behavior and by perceptions of dangerousness. The study empirically demonstrates countervailing processes in police decision making—recognition of the causes for troublesome behavior and the need for mental health treatment on the one hand and concern for community safety and enforcing the law on the other. 相似文献

Sex determination is critical for developing the biological profile of unidentified skeletal remains. When more commonly used elements (os coxa, cranium) for sexing are not available, methods utilizing other skeletal elements are needed. This study aims to assess the degree of sexual dimorphism of the lumbar vertebrae and develop discriminant functions for sex determination from them, using a sample of South African blacks from the Raymond A. Dart Collection (47 males, 51 females). Eleven variables at each lumbar level were subjected to univariate and multivariate discriminant function analyses. Univariate equations produced classification rates ranging from 57.7% to 83.5%, with the highest accuracies associated with dimensions of the vertebral body. Multivariate stepwise analysis generated classification rates ranging from 75.9% to 88.7%. These results are comparable to other methods for sexing the skeleton and indicate that measures of the lumbar vertebrae can be used as an effective tool for sex determination. 相似文献

Diagnostic Value of PSA and AP Tests for the Detection of Spermatozoa in Postmortem Swabs from the Genital and Anal Region in Males 下载免费PDF全文
Laurence Weitzig M.D. Ann Sophie Schroeder M.D. Ph.D. Christa Augustin Ph.D. Tobias Raupach M.D. M.M.E. Susanne Sehner M.Sc. Sven Anders M.D. M.M.E. 《Journal of forensic sciences》2015,60(1):41-44
The aim of this study was to clarify whether positive results for prostate‐specific antigen (PSA) and acid phosphatase (AP) occur in postmortem swabs from the genito‐anal region in males (n = 80; 4 regions) and females (n = 20; 3 regions) and to calculate the positive predictive value (PPV) concerning the presence of spermatozoa. In male subjects, the highest incidence of positive test results was found in urethral swabs (PSA 76%, AP 71%) and the lowest frequencies appeared in perianal and rectal swabs (15–20%). Microscopic evaluation for spermatozoa was positive between 39% in urethral swabs and 1% in rectal swabs. PPV regarding positive identification of spermatozoa was 33.3% for PSA and 31.5% for AP. The combination of both tests yielded a PPV of 38.2%. In female cases, no spermatozoa were identified, and one case was PSA‐ and AP‐positive in perianal swabs. Our findings indicate that PSA and AP tests are of limited value for the postmortem detection of spermatozoa in male subjects. 相似文献

The president is the most influential policy actor in US politics, and his legislative program greatly influences Congress's agenda. Yet little research has focused on what factors affect the president's choices when constructing his agenda. We develop a theory that determines when a president will include an issue in his program. We hypothesize that presidents structure their agendas around the congressional calendar for consideration of expiring laws and salient issues. Using data over 28 years and across 12 policy areas, we find presidents build their programs around these policymaking opportunities. We assert that presidential agendas are less driven by individual priorities than previous accounts have concluded. 相似文献
