This article builds on recent contributions to the academic literature on lone wolf terrorism to critically examine key issues that are germane to the current state of play in this field of study. It finds that, overall, the recent academic literature still suffers from considerable problems regarding quality and rigor, including definitional, conceptual, methodological, and inference issues. By providing a critique of these issues, the article attempts to advance the scholarly debate on lone wolf terrorism and inspire greater dialogue and collaboration between scholars. Directions for future research are also outlined.  相似文献

This article explores the European Commission goal of improving the quality and level of accessibility in mainstream information and communication technology (ICT) goods and services available in Member States through the use of public procurement legislation and performance standards. Over the past two decades, the Commission has encouraged Member States to adopt common requirements for accessibility and to strengthen efforts to use these requirements in public procurement. In the absence of significant improvements in the level of accessibility over this time, the Commission has more recently committed to bringing forward legislative proposals to harmonize the accessibility requirements used by Member States. A new procurement directive package contains stronger obligations on public bodies to include accessibility as mandatory requirements in Technical Specifications. In parallel to this, a standardization mandate by the Commission to the European Standards Organizations (ESOs) concluded in March 2014 with the publication of the first European standard on ICT accessibility. In light of these developments, this article analyses the trajectory of European policy in the field of accessibility over the last two decades, and the interplay between European public procurement, standardization and law. It examines how far these developments have succeeded in bringing into being a public procurement eco-system that will nudge the market in Europe to producing affordable and accessible ICT products and services for persons with disabilities.  相似文献

In recent decades rural violence has escalated in many Latin American countries. Although there is a growing body of literature on the topic, there exist as yet few comparative studies. While there are undoubtedly multiple and evolving causes of violence, this exploratory article focuses on the relationship between sociopolitical violence and agrarian structure and state policy. Particular attention is paid to the impact of agrarian reform and counter-reform experiences on rural conflicts and violence. A contrast is also drawn with countries which have not undergone any significant land reform. The cases discussed are Chile, Peru, Colombia, Brazil, Mexico and several Central American countries (Nicaragua, Guatemala and El Salvador). The complexity of rural violence is demonstrated and the case for further comparative studies is argued, so as to advance our knowledge on the causes, consequences and resolution of violence.  相似文献

The EU's ineffectiveness vis‐à‐vis Libya and the southern Mediterranean crises more broadly is largely explained by the CSDP's narrow mandate centred on crisis management. The EU's emphasis on external crisis management was strategically sound given the geopolitical context of the 1990s. CSDP's quiet drift towards a ‘softer’ kind of crisis management from the middle of the first decade of the 2000s was also instrumental in highlighting the EU's differences from post‐11 September US unilateralism. That said, (soft) crisis management has become progressively obsolete in the light of a rapidly changing geopolitical environment characterised by an overall retreat of Western power globally, a weakening of America's commitment to European security, an increasingly tumultuous European neighbourhood, and Europe's financial troubles. In order to meet the demands of a changing geopolitical environment, CSDP must break away from its distinctively reactive approach to security to include all the functions normally associated with the military including, chiefly, deterrence and prevention. This would allow the EU to actively shape its regional and global milieu.  相似文献

According to Gamson’s Law, the allocation of cabinet portfolios in parliamentary democracies is proportional to the legislative seat shares of the governing parties. However, portfolio allocation departs systematically from perfect proportionality. This paper proposes a theory of portfolio allocation that seeks to explain the variance in proportionality across different bargaining situations. It argues that the degree to which the coalition formation process is characterised by uncertainty and complexity influences portfolio allocation. In uncertain and complex bargaining situations, parties that otherwise would be in an advantageous bargaining position will have a difficult time exploiting their bargaining advantage. As a result, portfolio allocation in such circumstances will be closer to proportionality. These patterns are observed in data on coalition formation in 14 West European parliamentary systems in the period 1945–1999.  相似文献

In the framework of the DRUID (Driving under the Influence of Drugs, Alcohol, and Medicines) EU-6 project, a roadside survey was performed in South-East Hungary to determine the incidence of alcohol and the most frequent illicit and licit drug consumption (amphetamines, THC, illicit and medical opiates, cocaine, ketamine, benzodiazepines, zopiclone and zolpidem) in the general driving population. All 3110 drivers stopped between 01 January 2008 and 31 December 2009 were checked for alcohol, and among them 2738 persons (87.7%) participated in the further examinations, on a voluntary basis. Licit and illicit drugs were determined from their oral fluid samples by GC–MS analysis.Illicit drugs were detected in 27 cases (0.99%), licit drugs in 85 cases (3.14%), and alcohol (cut off: 0.1 g/l) was found in 4 (0.13%) cases. Illicit drug consumption was the highest among men of the ages 18–34, during the spring, and on the week-end nights. With respect to licit drugs, the highest incidence was found among women over the age of 50, during the summer, and on the week-days. All alcohol positive cases were men over the age of 35. In comparison to international European averages, the alcohol and illicit drug consumption was low, but the licit drug consumption was over the European average.  相似文献

This article contributes to the study of legislative organisation by contrasting the process of committee chair selection in two distinct institutional environments. The goal is to verify how party loyalty affects the distribution of committee chairmanship in the Brazilian Chamber of Deputies, focusing on two distinct historical periods. The main hypotheses are tested using a data set that contains information about federal deputies' career characteristics, both inside and outside the Chamber, measured on an annual basis, in two distinct democratic periods – 1946 to 1964 and 1989 to 1998. The article's main conclusions are: first, in a situation where parties are oriented by a factional logic and where power distribution between party leaders and committee chairs is more equal, party loyalty is a crucial factor in the allocation of committee chairmanships. Second, in a broader perspective, the interaction between committees and parties cannot only be explained by incentives emanating from the electoral connection, for it also suffers from the influence of executive–legislative relations.  相似文献
