It is common for researchers using animal or human remains for scientific study to freeze samples prior to use. However, effects of freezing on bone macro‐ or microstructure are relatively unknown. The research objective of this study was to determine whether freezing could potentially bias experimental results by analyzing changes in bone mineral density (BMD) with the freezing of remains over time. Eight fetal pigs were scanned to determine their initial BMD before freezing. Three piglets underwent a freeze‐thaw cycle to assess the effects of the freezing process. Four piglets were frozen and scanned weekly for 20 weeks to assess freezing over time. The overall average between the fresh initial scan and final frozen scan was significantly different (p < 0.001). Per contra, the final thawed BMD scans did not differ from the initial fresh scan (p = 0.418). Thus, completely thawed remains are recommended for experimental studies.  相似文献

Although many countries have ethnic kin on the “wrong side” of their borders, few seek to annex foreign territories on the basis of ethnicity. This article examines why some states pursue irredentism, whereas others exhibit restraint. It focuses on the triadic structure of the kin group in the irredentist state, its coethnic enclave, and the host state, and provides new data on all actual and potential irredentist cases from 1946 to 2014. The results indicate that irredentism is more likely when the kin group is near economic parity with other groups in its own state, which results in status inconsistency and engenders grievances. It is also more likely in more ethnically homogeneous countries with winner‐take‐all majoritarian systems where the kin group does not need to moderate its policy to win elections by attracting other groups. These conditions generate both the grievance and opportunity for kin groups to pursue irredentism.  相似文献

As the only Sunni Islamic Republic in the world, Sudan's middle‐class, modernist Islamist revolution can be seen as a model for the mobilization of public consciousness about citizenship in an Islamic state. That this citizenship is consciously and conspicuously gendered is the main theme of this paper. In the north, where mobilization has been most successful, Sudanese women have both been constructed and have constructed themselves as the woman citizen— mother, Muslim, and soldier. A brief historical background reveals complicated shifts in national, local, and gender identities, from the colonial state to the present. The crux of the paper is an exploration of state hegemonic strategies, including the manipulation of gender and other identities, especially as these are manifested in the fashioning of the ‘new Muslim woman’. Women's complicity in and resistance to these constructions are among the dynamics of contemporary northern Sudan. The paper also explores the waning of ‘Arab’ identity claims in the face of state emphasis on Islamic identity and the relevance to Islamist women. Interview statements by Islamist women attest to both their complicity in and resistance to their construction as members of the Islamic nation/community.  相似文献

The investigation of sudden unexpected death in psychiatric patients and the ensuing litigation has brought to our attention many unusual features important in the evaluation of such deaths. Certain pathophysiologic mechanisms of death, rarely encountered in routine forensic science practice, may be important in determining the cause of death in psychiatric patients, especially in cases where the autopsy is unrevealing. Of particular concern is a tendency in the current literature to implicate phenothiazines as a cause of death when the death investigation and the autopsies are incomplete. Thus, based on our experience and on a review of the current literature, we have set forth factors that the forensic pathologist should consider when faced with a sudden psychiatric death. A case report illustrates these unique aspects of scene investigation and analysis of terminal events and autopsy findings.  相似文献

Recent trends in sentencing in England and Wales are discussed and related to the debate concerning the relationship between unemployment and imprisonment. The shift towards a more punitive justice system are traced to the abandonment of full employment economic policies in the mid 1970s.  相似文献
