The main objective of this article is to examine how the links between trade unions and affiliated political parties of the left influenced the strategies of labour during the transition and the early years of democracy in Spain. It argues that political partisanship is a key factor for understanding the unions' strategies. After a period of intense labour conflict during the transition to democracy, labour mobilization decreased and Spain's unions and other social actors initiated distinctive processes of social bargaining, starting in 1979. The central argument is that the relationship of unions and political parties in the authoritarian and transition periods was a major factor in conditioning strategies in the post-authoritarian period. In the end, the consolidation of Spanish democracy has led to the strengthening of the main trade unions. Contrary to what happened in other historical periods they used this power to contribute to governability and the consolidation of the new democratic regime.  相似文献

While the literature on peacekeeping has mostly focused on whether peacekeeping actually keeps the peace, few studies have systematically addressed the question of what explains variations in unintended consequences of peacekeeping, such as sexual exploitation and abuse (SEA). This study presents the Sexual Exploitation and Abuse by Peacekeepers data, a new dataset covering the 36 international peacekeeping missions by the UN, NATO, ECOWAS, and the African Union, active in the years 1999–2010. Using this dataset, it also presents the first statistical study that explores the issue of what can account for variations in reported SEA across peacekeeping operations. The systematic analysis of this data indicates that SEA was more frequently reported in situations with lower levels of battle-related deaths, in larger operations, in more recent operations, the less developed the country hosting the mission, and in operations where the conflict involved high levels of sexual violence. Our discussion and conclusion highlights data restrictions and identifies key challenges for future research.  相似文献

ABSTRACT

In the conceptual literature on terrorism, there is no shortage of answers to the question: “What is terrorism?” Indeed, the terrorism literature has been heavily criticized for a deluge of definitions. And yet the booming quantitative terrorism literature generally examines a narrow set of “what is terrorism?”: how country-level factors explain variation in the number of terrorist attacks. This article demonstrates the variety of ways in which scholars currently operationalize terrorism and compares them to the ways it could be operationalized. I replicate studies using alternative operationalizations of terrorism to examine the consequences of the terrorism literature’s collective bet to focus on attack counts at the country level. Finally, I discuss the implications of the narrow set of operational choices with an eye towards how a greater variety of approaches would produce a more robust research agenda.  相似文献

In this article, wavelet tools and economic sentiment indicators are used to study the similarity and synchronization of economic cycles in the eurozone. The time‐varying and frequency‐varying patterns of business cycles synchronization are assessed and the impact of the creation of the European monetary union (EMU) in 1999 is tested. Among several results, it is found that: the EMU is associated with a significant increase in the similarity and synchronization of the economic sentiment in the eurozone; and the hard‐peg of its currency to the euro led to a comparable effect on Denmark's economic sentiment after 1999, different from what happened in the United Kingdom.  相似文献

本文概览了澳大利亚、加拿大、新西兰、香港等四个主要的环太平洋普通法系国家和地区的传闻法律改革,尤其关注与先前不一致陈述相关的改革。指出先前不一致陈述事关\"被告人获得公平对待\"以及\"证人的人权\"等基本原则,因此,如何对待先前不一致陈述将成为一项有效的指标,通过该指标。我们得以评价传闻法律改革中的关键原则以及个人权利在大多数严重犯罪的起诉、审判过程中的境况。认为无论借助成文法还是借助先例,公正的传闻法改革应当适用某些相互一致的基本原则,包括放宽采纳传闻的条件决不能以错案数量增长或不公正审判为代价,将传闻改革与保护被告人、证人的基本权利紧密联系起来,保护证人不受任何形式的强迫或不当侦查行为的干扰,辩护律师必须能够无拘束地对陈述可采性加以质疑,通过充分、及时地开示证据来分析有争议的证据的可采性等。  相似文献

A method for the simultaneous determination of cocaine (COC) and cocaethylene (CE) in human hair was developed, using solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) as analytical technique to identify and quantify the drugs. Selected ion monitoring (SIM) mode was used to obtain higher sensitivity. The deuterated-labeled analogues were used as internal standards. The detector response was linear for the drugs studied over the range 0.4-15 ng/mg, with correlation coefficients higher than 0.995. The coefficients of variation oscillated between 0.65% and 14.18% and the accuracy was in the range from 0.73% to 11.20%. The limits of quantitation and detection were found to be acceptable. Finally, this method was applied to 15 hair samples from cocaine users, obtaining positive results in all cases. The mean concentrations were 5.39 ng/mg (range: 0.43-8.98 ng/mg) for cocaine and 1.11 ng/mg (range: 0.42-2.23 ng/mg) for cocaethylene.  相似文献

This study addresses how and why individuals in Somalia get involved in piracy activities, and how and why some of these individuals eventually disengage from such criminal groups. Based on qualitative interviews with 16 ex-pirates and pirate associates and a number of other locals and experts, the study provides first-hand insights into some of the conditions, circumstances, and processes which may serve to discourage involvement and continued engagement in piracy. Furthermore, it analyses factors and circumstances which may encourage and facilitate disengagement from these criminal activities and reintegration into non-criminal economic activities and social relationships. The lack of employment and livelihood motivated individuals to engage in piracy. However, disappointment about the lack of expected profit, coupled with the prospect of a licit income, influenced some to end their piracy involvement. Another important factor was the strong statements by local Muslim leaders that piracy was haram (forbidden). This was often reinforced by family and community objections to their involvement in piracy. Family members also played important roles in facilitating their disengagement. The ‘Alternative Livelihood to Piracy’ project played a positive role in facilitating disengagement from piracy, working closely with local religious leaders and the communities.  相似文献

Abstract

This article assesses the prospects for Costa Rica's new Biodiversity Law. We believe that this analysis could also provide a valuable case study of national implementation of the Convention on Biological Diversity (CBD). The article is not intended to be a primer on the CBD, nor will it defend its precepts. The authors believe that each nation must formulate a legal framework to regulate biodiversity that reflects their unique national circumstances.  相似文献
