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

Juvenile Justice‐Translational Research on Interventions for Adolescents in the Legal System (JJ‐TRIALS) National Survey was funded in part to describe the current status of screening, assessment, prevention and treatment for substance use, mental health, and HIV for youth on community supervision within the US juvenile justice system. Surveys were administered to community supervision agencies and their primary behavioral healthcare providers, as well as the juvenile or family court judge with the largest caseload of youth on community supervision. This article presents the findings from the judges’ survey. Survey results indicated juvenile and family court judges were open to innovations for improving the court's performance, rated their relationships with collaborators highly, and appreciated the impact of screening, assessment, prevention, and treatment on judicial practices.  相似文献

This article considers whether the King's Bench decision in Godden v Hales (1686) allowing James II to dispense with the application of the Test Acts was correct. Most modern historians believe that the decision was either correct, or at least a justifiable interpretation of the legal precedents; contemporaries overwhelmingly believed the decision was wholly wrong. This article explains the nature and importance of the dispensing power, and considers the relevant case law precedents in detail. It concludes that the line of authorities forbidding the king from dispensing with the anti-simony statutes should have been applied to the Test Acts. The accusations of illegal and unconstitutional conduct relating to the dispensing power made against James II during the 1688 Revolution and in the Declaration of Rights were thus wholly justified.  相似文献

ABSTRACT: Massive enlargement of an ovarian cyst is an uncommon cause of morbidity and a rare cause of mortality due in large to part to noninvasive imaging techniques that usually permit early detection. When an ovarian cyst reaches giant proportions, it produces abdominal enlargement often with a fluid wave resulting in a condition that mimics ascites, called pseudoascites. Despite their impressive appearances, such cysts often are operable for cure. We describe a case of a middle-aged woman who presented 3 years before her death with symptoms from an undiagnosed giant cyst and given a diagnosis of ascites of undetermined etiology. She subsequently died at home unexpectedly, and at autopsy, she was found to have a massively enlarged but otherwise benign mucinous cystadenoma.  相似文献

Contemporary public service leaders are no longer the anonymous mandarins of Westminster folklore. Whether giving public speeches to outside organizations or communicating directly with the media, senior public servants are emerging from anonymity to become public actors in their own right. This article undertakes a comparative study across four Westminster jurisdictions—Australia, Canada, New Zealand, and the United Kingdom—to examine the formal rules and guidelines that apply to public servants when making public statements in their official capacity. Drawing on the late Peter Aucoin's notion of “promiscuous partisanship,” the article argues that public servants are expected to demonstrate a new level of enthusiasm when explaining or justifying government policy to the public. This has implications for the extent to which nonpartisanship can continue to effectively function within Westminster systems.  相似文献
