Navigating the Unknown: Barriers to Evidence-Based Defence and Security Policy in the European Union
Benedict Wilkinson Maria Giulia Amadio Viceré Erin Montague 《The international spectator : a quarterly journal of the Istituto affari internazionali》2017,52(1):88-99
At a time when Europe faces numerous crises, there is a real need for rigorous evidence to underpin effective policymaking. However, a gap between academia and policy creates clear obstacles in the use of evidence in policymaking. Many of these enduring obstacles are manifest in the inherent differences between separate communities: academics have difficulty communicating research in an applicable manner, and policymakers, in turn, tend to focus on operational motivations. The gap widens considerably when foreign, security and defence policy within the complex institutional structures of the European Union is considered. In addition to these well known barriers to evidence-based policy, there are two more obstacles in the defence and security space: sovereignty and dispersed decision-making. A dialogue of best practices must be opened up to broker knowledge in the EU context. 相似文献

This article synthesizes the cross‐disciplinary literature on government transparency. It systematically reviews research addressing the topic of government transparency published between 1990 and 2015. The review uses 187 studies to address three questions: (1) What forms of transparency has the literature identified? (2) What outcomes does the literature attribute to transparency? and (3) How successful is transparency in achieving those goals? In addressing these questions, the authors review six interrelated types of transparency and nine governance‐ and citizen‐related outcomes of transparency. Based on the findings of the analysis, the authors outline an agenda for future research on government transparency and its effects that calls for more systematically investigating the ways in which contextual conditions shape transparency outcomes, replicating studies with varying methodologies, investigating transparency in neglected countries, and paying greater attention to understudied claims of transparency such as improved decision making and management. 相似文献

15 May 2011 marked the beginning of a major political and regime crisis in Spain. It has since passed through different stages – the last being the emergence of Podemos, which has become a major player in Spanish politics. The crisis of traditional mechanisms of political representation has become a crisis of hegemony of the ruling class, in the Gramscian sense of the term. The mass support for the ruling class and its traditional form of political representation has been withdrawn. This has led to an open situation with no clear outcome that can be read in terms of Walter Benjamin’s non-linear and deterministic sense of political and historical time. 相似文献

Political trust has in previous studies mainly been associated, either positively or negatively with a set of political variables, such as subjective knowledge of and interest in political issues, political efficacy, national pride, post-materialist values and corruption permissiveness. More recently, it has been debated whether or not indicators of social capital also have an impact on political trust. It has been argued that social capital helps to sustain civic virtues and that lack of it will create democratic problems like political dissatisfaction and declining political participation. While trends in social capital seem stable and high at the aggregate level in Finland, the level of political trust has varied to a much larger degree. In this article, indicators of social capital, political variables and social background variables are set against the Finns' trust in politicians and the parliament as well as their satisfaction with democracy. The analysis shows that social capital, as defined by a set of variables comprised of interpersonal trust and voluntary organisational activism, does not, en bloc, prove to be a powerful predictor of political trust. However, when the social capital items are examined as single factors, interpersonal trust seems to have strong impact on all levels of political trust, while the influence of voluntary organisational activity is less evident. 相似文献

Unpacking Acculturation: Cultural Orientations and Educational Attainment Among Mexican-Origin Youth
Given educational risks facing Mexican-origin children of immigrant parents, it is important to understand how aspects of the acculturation process influence Mexican-origin youth's educational success. Drawing from selective assimilation theory, this study examined how cultural orientations across myriad facets of acculturation were associated with the educational attainment of second-generation Mexican immigrant youth. The sample included 755 Mexican-origin youth (50% female) in the "Children of Immigrants Longitudinal Study." Results from structural equation models indicated that youth reporting greater facility in the English language and a stronger value on familism attained higher levels of education in young adulthood than did other youth. Parents' U.S. social ties and youth's value on early paid work were associated with less educational attainment. Innovative findings from this study indicate the importance of considering both Mexican and American cultural orientations across myriad facets of acculturation for understanding second-generation immigrant Mexican youth's educational attainment. 相似文献

The concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP-MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP-MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP-MS technique in forensic analysis. 相似文献
