In 1993, the skeletal remains of a female corpse were found in Burgenland, Austria. Initial identification of the approximately 25–35-year-old female appeared impossible, but the case was reopened 23 years later. By applying biogeochemical isotope methods to her body tissues, the geographical origin of the unknown corpse could be predicted. The results of the C, N, S, H, Sr, and Pb isotope analyses suggested that the female did not originate from Europe and most likely spent her youth in the northern Caribbean. Using these findings, the police were able to identify the woman within 2 weeks. The female came from the Dominican Republic and resided in Austria for only a short period before she was murdered. This case shows that isotope biogeochemistry investigations can provide the police with crucial information that enables unknown persons to be identified.
Keypoints
- C-N-S-H and Sr-Pb isotope analyses were applied to human remains associated with a cold case.
- It was possible to determine the region of origin of the unknown deceased individual as the northern Caribbean.
- After 23 years, the murder victim was successfully identified.

The changing shape of sustainability governance has been a key academic and policy concern in the past two decades, as part of a wider debate on the interactions between public and private authority in governing the economy, society, and the environment. In this article, we contribute to these debates by examining how these interactions operate locally and across jurisdictions in three conservation and development initiatives in Tanzania and what impact they have on the functional quality of sustainability governance. We find that clear division of responsibilities, coupled with material incentives for communities and equal and transparent distribution of benefits, are key positive contributors to functional quality. These factors underpin the complementary interactions (collaborative at the local level; institutional layering across jurisdictions) that are needed to successfully negotiate and implement the compromises needed to balance conservation and development goals. We also find that competitive dynamics are harmful to functional quality, especially those taking the form of local institutional duplication and of dominance by central government across jurisdictions. These tend to appear especially when sustainability initiatives involve multiple stakeholders with wide discrepancies in resources, interests, and power, which leads to compromises determined in a top-down manner. 相似文献

This paper presents a natural experiment, comparing the effects of two-round (TR) and proportional representation (PR) voting rules in French cantonal and regional elections. A series of rigorous model estimations demonstrates that the two electoral types clearly produce distinct outcomes. TR systems bring about less extremist party voting, less party competition, and perhaps less vote turnout, when compared to PR systems. These findings call into question the lack of attention to TR effects, and the notion that TR is not really a distinct electoral form. 相似文献

This essay introduces the contributions of the volume “Social Media, Political Marketing and the 2016 U. S. Election.” Using a variety of methodological approaches, the authors investigate the communication strategies of the Democratic and Republican candidates for president together with the responses of their audience. Collectively, this research offers insights into how new communication technologies are changing both political marketing and the ways candidates and voters interact. 相似文献
