AbstractDoes European soft law matter? In order to answer this question, the article investigates the processes through which the European Union (EU) affects domestic politics and policies in the eHealth sector in France, Austria and Ireland. More precisely, it shows how the hardening of EU soft law creates a new rationale for the use of European instruments by domestic actors, thus expanding their strategic opportunities for policy making at the national level. Despite the empirical diversity of the cases, similar patterns of variation in Europeanisation mechanisms emerge over time, and the data show how the varying structure of European soft instruments (i.e. their degrees of ‘hardness’) accounts for these changes. This comparative analysis includes multiple process-tracing cases of eHealth public policy making in France, Austria and Ireland in which Europeanisation processes are at work. 相似文献

In 2010, the Government of Ontario, Canada passed the controversial Far North Act. The Act purportedly aims to promote land use planning and sustainable development while recognising Aboriginal and Treaty rights. There are, however, early warning signs that the Act could be a breeding ground for future conflict between Indigenous peoples and other stakeholder groups. This article adopts a ‘sons of the soil’ conceptual framework to explore the mechanisms that could give rise to the escalation of Indigenous vs. non-Indigenous conflict. The findings provide important insights for theorising the contentious politics around land and territory in diverse settler-colonial contexts. 相似文献

ABSTRACTThis article takes as its focus the main Brazilian cultural and media product, the telenovela or soap opera, to discuss the characteristic of the Brazilian personality referred to as the homem cordial (“cordial man”). The article analyses two telenovelas: Renascer (1993) and Velho Chico (2016), which, written by the same author, but in very different historical contexts, sought to recover the trait of cordiality in its essence. In its comparison of the two telenovelas, this study presents and discusses the changes, permanencies and negotiations of a cordial tradition in the face of a particular aspect of modernity represented by both the process of urbanisation and by television itself. 相似文献

Estimating the applied power during a stabbing incident, or estimating the minimal force necessary to penetrate the body with a certain weapon is a challenging task in forensic practice. A thorough forensic evaluation of stabbing forces needs objective numerical experimental data. Stabbing tests of 12 different weapons – including knives, a pair of scissors, a fork, screwdrivers, a rasp, a corkscrew, and a utility knife blade – were performed with a Mecmesin MultiTest-dV material tester on pork loin and ballistic gel to estimate the stabbing forces and dynamics. Penetration force (Fp) and maximal force (Fmax) were recorded, and the registered force curves were analyzed. Fmax was 159.8–212.07 Newton (N), 30.56–30.58 N, 168.9–185.48 N for various knives; 171.39–190.43 N for the pair of scissors, 233.6 N for the fork; 532.65–562.65 N, 370.31–367.19 N and 314.51–432.89 N for various screwdrivers, 44.14–56.62 N for utility knife during pork loin stabbing. The butter knife, corkscrew and rasp were not able to penetrate the pork loin, and the curved fork bent during stabbing. The results prove that weapon characteristics greatly influence the force necessary for penetration. Maximal stabbing force depends mostly on tip sharpness, and the force sharply decreases after penetration occurs, which indicates that edge sharpness is not as important as tip characteristics during stabbing perpendicular to skin surface. The penetration force during stabbing with a pair of scissors is comparable to the penetration force of knives. Stabbing with screwdrivers generally needs larger force than average knives but depends greatly on screwdriver size. 相似文献

The secondary dentin deposition that occurs after the tooth formation process results in a decrease in pulp cavity volume in adolescents and adults. The purpose of this critical review was to correlate pulpal and/or dental volume on cone-beam computed tomography (CBCT) with chronological age approximation. A subobjective was to investigate which methodology and CBCT technical parameters would be most appropriate to evaluate this correlation. This critical review followed the PRISMA guidelines, and it was conducted by a search through PubMed, Embase, SciELO, Scopus, Web of Science, Cochrane Library databases, as well as gray literature. Primary studies that used pulp volume, or pulp chamber to tooth volume ratio measured using CBCT were included. Seven hundred and eight indexed and 31 non-indexed records were identified. A qualitative analysis was performed including 25 selected studies with a total of 5100 individuals, age ranging from 8 to 87 years without sex predilection. The most used method was pulp volume/tooth volume. CBCT voxel size ranged between 0.09 and 0.5. Manual segmentation associated with threshold algorithms was used in most of the studies. Correlation between the pulp volume/tooth volume ratio was moderate: −0.66 for the upper central incisors, −0.59 for upper canines and −0.56 for lower canines. High heterogeneity was observed among the studies. It is concluded that pulp volume should be used with caution in age estimation. Evidence supports the preferable use of upper incisors with pulp volume/tooth volume ratio for age estimation. There is not enough evidence that voxel size interferes in age estimation by pulp volume. 相似文献

The aim of this article is to analyse citizens’ attitudes towards governmental accountability in 24 European countries and to examine the influence of contextual and individual factors on perceptions of accountability. Using as a dataset the 2012 European Social Survey, the results show that citizens respond positively when the media provides reliable information on which to judge the government, when individuals perceive that governments perform well, when individuals live in more extensive and generous welfare states and when they live in countries where the rule of law is firmly established. In addition, the findings also provide evidence that compared to politically left-wing citizens, right-wing supporters have, on average, a higher perception of governmental accountability. In particular, the findings show strong positive evaluations of right-wing governments by right-wing voters in comparison with left-wing governments by left-wing voters. 相似文献

Rapid advances in our ability to collect, analyze, and disseminate information are transforming public administration. This “big data” revolution presents opportunities for improving the management of public programs, but it also entails some risks. In addition to potentially magnifying well‐known problems with public sector performance management—particularly the problem of goal displacement—the widespread dissemination of administrative data and performance information increasingly enables external political actors to peer into and evaluate the administration of public programs. The latter trend is consequential because external actors may have little sense of the validity of performance metrics and little understanding of the policy priorities they capture. The author illustrates these potential problems using recent research on U.S. primary and secondary education and suggests that public administration scholars could help improve governance in the data‐rich future by informing the development and dissemination of organizational report cards that better capture the value that public agencies deliver. 相似文献
