Piophila megastigmata McAlpine, 1978, for many years only known from South Africa, was recently recorded in Spain. The present work reports for the first time the occurrence of P. megastigmata in human corpses in Portugal. The species was also collected in succession studies conducted with piglet carcasses, where it coexisted with Stearibia nigriceps (Meigen, 1826), showing similar periods of presence in the carcass. However, P. megastigmata was more abundant than S. nigriceps in autumn, with the opposite in summer. During winter neither species was able to colonize carrion and in spring, only S. nigriceps. This first record of P. megastigmata in human corpses confirms it as a potentially useful forensic species in Europe. The species, well established in the Iberian Peninsula, probably has a wider distribution but has been previously overlooked and possibly confused with Piophila casei (Linnaeus, 1758) in many studies. 相似文献

Abstract: Most studies of long‐term chondrocytes survival were for tissue banks. They showed a gradual reduction in the viable chondrocytes percentage as a function of time and ambient temperature, but the samples were harvested under optimal conditions. The aim of our study was to determine the most reliable combination of cartilage source and assay for the in vitro postmortem chondrocyte viability analysis in the conditions that imitate a dead body. Osteochondral cylinders were procured from femoral condyles and talar trochleas of three male donors and stored in the cell culture media at 4 ± 2°C and 23 ± 2°C. The samples were analyzed by a cell viability analyzer and a confocal laser scanning microscope (CLSM) initially 24–36 h after death and then in 4‐week intervals. The results reconfirmed the significant influence of time (p = 0.0002), but not of the temperature (p = 0.237). The largest reproducibility was presented for the knee joint and the CLSM. 相似文献

This article examines the judicialization of electoral politics in Asia, an important but understudied trend, as demonstrated in Thailand and Indonesia. Though the constitutional courts in both have similar histories and institutional arrangements, their electoral interventions vary radically. We argue that the diffusion or concentration of power among post‐transition elites determines whether the effect of judicial activism will be to shore up or undermine electoral governance. Where power is diffused, as in Indonesia, political actors, less able to impose their own will on the judiciary, seem to prefer a credible referee, which fosters electoral competition. Where power is concentrated, as in Thailand, elites have both the motive and the means to turn judicial activism to antidemocratic ends. By focusing on the ends, rather than the means, of judicial activism, this account goes beyond personalities and institutional design to enhance understanding of the role of the courts in transitional democracies. 相似文献

The main purpose of this study was to present changes occurring between 2002 and 2004 in the prevalence of psychosocial constraints and interpersonal violence at work among officers working in correctional facilities in Quebec. Results suggest that in the absence of specific organizational intervention aimed at improving a deleterious work situation, exposure to low decision latitude remained similar between 2002 and 2004, while exposure to high psychological demands improved somewhat, for both men and women. In 2000, rates of exposure of correctional officers in Quebec to high psychological demands, low decision latitude and the combination of high psychological demands and low decision latitude (job strain) were significantly higher than those obtained for the entire population of workers in Quebec in contact with the public. Exposure of correctional officers in Quebec to intimidation at work increased substantially between 2002 and 2004, among both men and women. Globally speaking, rates of exposure to intimidation by colleagues and superiors practically doubled between 2000 and 2004. Rates of exposure to intimidation among correctional officers in Quebec were particularly high in 2004 (71% among men 66% among women) compared to rates in another study conducted among federal correctional officers (48%) by Samak. The present study also showed that in 2004, correctional officers in Quebec were more likely to present signs of psychological distress linked with work when they were exposed to high psychological demands, low decision latitude, job strain and poor social support from superiors and colleagues. Psychological distress was also shown to be greater when reward at work was scarce and when there was an imbalance between effort and reward at work. Finally, in 2004, psychological distress among correctional officers was also associated with intimidation and psychological harassment at work. 相似文献

While intersectionality is a recurrent theme in the literature on women's political representation, few studies empirically disentangle who are the women who get elected to parliaments. An argument on biases in recruitment practices suggests that those who are members of more than one outgroup, such as young women, benefit from an ‘outgroup advantage’. In elections, a candidate with two outgroup features might attract more voter support than a candidate with just one outgroup feature. Hence, nominating a candidate that is both young and female could be a rational move by (male) elites in political parties that allows them to open fewer seats to newcomers. These expectations are tested on data for all members of the European Parliament since 1979. Not only is it found that women's presence increased steadily throughout the parliament's history, but also that women's representation is consistently highest among the group of young representatives, lower among middle-aged Members of the European Parliament and lowest among older representatives. 相似文献

Global diffusion of regulatory reforms in telecommunications has prevailed in many countries, engendering major institutional changes and entailing the establishment and/or reform of regulatory agencies. Although the triggers and timing of such agentification processes have been more or less similar, agency independence displays significant cross-country variation. Seeking to explain such variation based on a sample incorporating middle-income countries (MICs), this paper examines the impact of political-institutional settings in which the agencies operate, in addition to the impact of economic parameters. Regression analysis reveals that political rights appear as the central parameter, while their impact is more robust in MICs than in advanced countries. The results underscore considerable cross-national variation in regulatory governance, along with a noteworthy decoupling between MICs and advanced countries. Concurring with the regulatory regionalism perspective, the paper delineates distinct regional clusters, albeit remaining agnostic about the determinants of such clusters. 相似文献
