Using the Princeton nuptiality index Im, we analyzed historical developments in the proportion of married women of reproductive age in Spain. We show the internal diversity in nuptiality patterns and offer an explanatory statistical model based on panel data analysis to identify the main variables influencing these changes over more than a century (1887–1991). We found that Spain has been the developed country with the greatest contrasts in its provincial nuptiality patterns (measured by Im), although this diversity has lessened over the course of time. We also found that some socioeconomic variables (the gross domestic product per capita and the percentage of population living in cities) do not have a linear relationship with female nuptiality but rather have a U shape or an inverted U shape. This may partly account for some of the controversy that has raged on this topic over the past few decades on an international level.  相似文献

This article analyses the relationship between stigmatisation, violence and marginality, and its limits to social justice and citizenship. It involves a critical reflection on the way groups living in ‘a social and symbolical shade’ are represented and treated by governments and their institutions, and the way such practices reinforce a cycle of socio‐symbolical marginality and the limits to life in the city. The article will explore the findings of a research within drug gangs in which I have been involved ( Observatório de Favelas, 2006 ; Silva et al., 2009 and, Silva and Urani, 2002 ), and my own research on violence, urban marginality and stigmatisation ( Fernandes, 2009, 2012 ).  相似文献

Recent studies on European Union (EU) Enlargement have emphasised the importance of usages of ‘Europe’ by domestic actors as a necessary condition for the EU to have an impact on domestic politics. We study the usages of Europe in the critical case of Turkey’s nuclear energy policy. We analyse the narratives and actions of domestic actors in Turkey to identify if they use ‘Europe’ (the EU and the idea of Europe). We reach the counter-intuitive finding of usages by both state and non-state actors, which illustrates that usages of Europe can persist despite enlargement stasis in candidate states.  相似文献

While the January 2015 Paris terrorist attacks presented a crucial opportunity for far-right mobilisation, the focus on liberal democratic values and Charlie Hebdo’s non-conformist progressive profile presented challenges for right-wing discourse. Taking Italy as a paradigmatic case of public controversies on cultural and religious affairs, this article examines the opportunities and constraints generated by multicultural crises for far-right framing choices. A qualitative frame analysis analyses the discourse of three types of far-right actors. While the populist radical right, extreme right, and ultra-religious right groups disagree on crucial criteria for outgroup exclusion, they collectively employed the Charlie Hebdo controversy to redefine their exclusionary discourse on liberal grounds with the goal of gaining legitimacy in the mainstream public sphere.  相似文献

The paper investigates party-union relationships in Italy (1946–2014) by hand-coding parties’ parliamentary speeches and trade unions’ congress motions. In line with the cartel party thesis, a time series analysis shows that the ideological closeness between the left-wing Italian General Confederation of Labour and left-wing parties deteriorated when the Italian Socialist Party (1980) and the heirs of the Italian Communist Party (1998) converged toward the centre of the ideological spectrum. Conversely, the closeness between the Catholic-inspired Italian Confederation of Workers’ Unions and the heirs of Christian Democracy increased after 1994, when the former party’s leftist factions became the major part of the Italian Popular Party.  相似文献

Research on autocracies has gained new momentum in the last decade. One element of this research is the observation that some autocracies are characterised by structural conditions that are normally conducive for democracy. These ‘anomalous autocracies’ have high levels of socioeconomic development and democratic neighbour countries. The study of these cases might expose factors that are decisive for autocratic stability and studying them might give us a better understanding of barriers towards democratisation. This paper contributes to the growing literature on autocracies by mapping anomalous autocracies during the third wave of democratisation, thereby paving the way for systematic case selection in future studies. A large-N analysis of 159 cases (1975–2008) identifies Belarus, Chile, China, Cuba, Morocco, North Korea, Peru, Singapore, Swaziland, Togo and Zimbabwe. In a second step, the paper lays out a theoretical framework that centres on actors and institutions. Rulers must establish elite–elite and elite–mass interaction, and this papers argues that they can do so through quasi-compliance of elites and the masses based on traditional institutions woven into a dominant party. The paper uses the framework to tentatively examine the resilience of authoritarian rule in Swaziland and Morocco, two most-different anomalous cases. In both cases, an elaborate traditional institution has co-opted government, business and rural elites and coordinated interaction within elite circles and with the masses, in turn enabling the remarkable regime resilience.  相似文献

Short tandem repeat (STR) profiling is one of the mostly used systems for forensic applications. In certain circumstances, STR profiling is time-consuming and costly, which potentially leads to delays in criminal investigations. LGC (Laboratory of the Government Chemist, UK) Forensics has developed a robust STR profiling platform called the ParaDNA® Intelligence Test System which can provide early tactical intelligence and aid investigators in making informed decisions on sample prioritization for detection. Here, we validated the ParaDNA intelligence test for its application in forensic cases using a range of mock evidence items following guidelines set by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Specifically, we tested the sensitivity and accuracy of the ParaDNA intelligence test, as well as the success rates for detecting mock samples and for use in case scenarios. Our findings demonstrate that the ParaDNA intelligence test generates useful DNA profiles, especially for samples such as blood, saliva, and semen that contain ample DNA, indicating the benefits of including ParaDNA as a prior step in forensic STR profiling pipelines.  相似文献
