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

Based on the evolution and institutional transformation of the Welfare State and its relationship with the Third Sector of Social Action, the present article describes and analyzes the aspects of the financial crisis and resources that the sector is currently suffering. In regards of these structural transformations the evolution, characteristics, limitations and opportunities offered by ‘civic crowdfunding’ in Spain between the years 2011 and 2015 as an innovative social practice for the increase of the own funding between the entities of the Third Sector of Social Action and the changes that must be experienced by the sector in order to optimize and improve its self-funding ratios through this mechanism are examined. The high index of success of financing social projects (96.5%) through this tool, and the annual growth during the analyzed period shows the potential of civic crowdfuding. On the other hand, the small size of the bankable projects (95.2% less than 10,000 euros), as well as the low total amount collected (2,665,384 euros) indicates that civic crowdfunding is still an insufficient mechanism to mitigate the severe public resource cuts suffered by the entities of the Third Sector of Social Action and also to bring these entities closer to the objective of self-financing. Finally, we formulated a series of recommendations aimed at improving the self-financing ratios of the Third Sector of Social Action, including a more efficient and cooperative use of civic crowdfunding. 相似文献

Educational approaches that enable students to actively and directly participate in “real-world” projects are increasingly recognized as valuable pedagogical tools and, as such, being incorporated into university curriculums worldwide. Though not traditionally associated with political science courses, project-based international service learning presents a tremendous opportunity to bring classroom concepts and theories to life, provide an active approach to addressing international challenges, and assist students in the development of the hands-on, problem-solving, team-based, critical-thinking skills that are increasingly important to employers across all sectors. This article seeks to encourage political science faculty to incorporate international service learning—and/or project-based approaches—into their educational offerings. Through examination of the course Global Synthesis in Liberal Arts and Engineering Studies at California Polytechnic State University, we have identified multiple factors that can help promote successful execution of project-based international service learning as a pedagogical tool, and provide additional suggestions for faculty interested in adopting specific aspects of these educational approaches, and/or in doing so closer to home. 相似文献

Now in its sixth year, the war in Syria has triggered the largest humanitarian and refugee crisis of our time. For most refugees and migrants, Turkey is the main transit country to reach Europe, where Syrian refugees hope for a better future. However, this journey has been hampered as several European countries closed their borders following the arrival of an unprecedented number of migrants and asylum seekers in 2015. In response, a deal was struck with Turkey to stem the migrant flow to Europe in exchange for some concessions. By outsourcing the management of migration flows to Turkey, the EU is failing to take its fair share of responsibility for refugee protection. Furthermore, as a result of the political situation in Turkey and the unmet promises under the deal, relations between Turkey and the EU have touched their lowest point since the start of accession negotiations in 2005. While survival of the deal is of critical importance as the EU needs Turkey’s assistance in curbing migration flows and Turkey is keen on revitalising its accession negotiations, the deal has exposed serious flaws that need to be addressed and must not be replicated with other countries. 相似文献

It is a well-known fact that the transition to and consolidation of democracy in Latin America have been problematic, especially at the subnational level. It is also commonplace to equate an independent media system with a strong democracy. While each of these fields has witnessed important developments in the last decade or so, there have been sparse attempts to draw the theoretical links between them. In this article, I argue that there are important insights to be gained from such an endeavour. Bahia, a state in north-eastern Brazil, is an ideal case study to bring these perspectives together. This study offers fresh insights on state–society relations at the subnational level and on the contemporary interaction between the public and the private spheres in Latin America. Last but not least, it will also provide a better grasp on the challenges democratization faces at the subnational level and the role of the media in them. 相似文献

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method. 相似文献

Undocumented Border Crosser (UBC) deaths in Arizona are a major issue faced by medicolegal authorities. Currently, the Maricopa County Office of the Medical Examiner (MCOME) is in possession of over two hundred unidentified individuals, more than half of whom are presumed to be UBCs. The primary goal of this study was to address the growing number of UBC deaths in Maricopa County in order to provide a more comprehensive picture of this important anthropological issue within the state of Arizona. Of the 107 total UBC cases evaluated for the study, the majority were male and age estimates for all individuals were between 15 to 60 years old. Modeled after the recording system established by the Pima County Office of the Medical Examiner, the biographic and geographic data for these cases were entered into a new UBC database at MCOME and later added to the online Map of Migrant Mortality. 相似文献

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation. 相似文献
