How do political parties react to foreign security threats? There has been very little attention paid in the literature generally to how parties react to international events, particularly how parties react to foreign policy threats. Using data from the Comparative Manifesto Project, we examine how political parties in countries in Europe have reacted to Russian actions in terms of their emphasis on security issues. Based upon our analysis of the manifestoes from 331 parties in 36 countries we find that, generally, interstate threats have no significant effect on the military position adopted by political parties, although these effects vary by party type and by the type of threat. Russian based threats appear to be associated with the Far Left becoming more dovish (which is consistent with what would be expected by the literature) and the Far Right becoming significantly less hawkish. 相似文献

As transgender and gender-expansive (TGE) youth and young adults (YYA) navigate challenging environments, they often seek spaces for safety and acceptance. This study explores ways in which a group of TGE YYA who were engaged with a community-based service organization make sense of their experiences, challenges, and successes in ways that illuminate the factors and processes associated with resilience. Secondary data analysis was conducted on qualitative responses from 85 TGE YYA ages 13–24. The themes that emerged provide insight into the ways community-based programs and providers can understand and support the resilience of TGE YYA. 相似文献

With increasing frequency, relatively small, fragmentary evidence thought to be osseous or dental tissue of human origin is submitted to the forensic laboratory for DNA analysis with the request for positive identification. Prior to performing DNA analysis, however, it is prudent to first perform a presumptive test or "screen" to determine whether the questioned material may be eliminated from further consideration. When material is shown not to be consistent with bone/teeth, DNA testing is not performed. When such determinations cannot be made from gross morphological features, elemental analysis can be indicative. This presumptive test is made possible by applying scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) in conjunction with an X-ray spectral database recently developed by the FBI laboratory. This database includes spectra for many different materials including known examples of bone and tooth from many different contexts and representing the full range of taphonomic conditions. Results of SEM/EDS analysis of evidence can be compared to these standards to determine if they are consistent with bone and/or tooth and, if not, then what the material might represent. Analysis suggests that although the proportions and amounts of calcium and phosphorus are particularly important in differentiating bone and tooth from other materials, other minor differences in spectral profile can also provide significant discrimination. Analysis enables bone and tooth to be successfully distinguished from other materials in most cases. Exceptions appear to be ivory, mineral apatite, and perhaps some types of corals. 相似文献

The analysis of policy change has produced a number of contrasting theoretical approaches, each offering a lens through which to view policy phenomena. This article suggests that the existing menu of approaches for understanding change can be usefully complemented by an understanding of the role played by value conflict. Using institutionalist analysis, I argue that the need to make value‐choices in a nondisruptive way shapes large areas of government activity, particularly in Westminster systems, and explains many observed patterns of stability and change. Building on work by Thacher and Rein, I describe and characterize six types of response to value conflict, giving examples of the role and implications of each. It is not claimed that all policy change can be understood in this way—simply that some types of change reflect the value‐based nature of public policy itself, and the fact that political and bureaucratic systems must evolve mechanisms for dealing simultaneously with thousands of competing and conflicting policy values. 相似文献
