A retrospective, cross-sectional analysis of vitreous beta-hydroxybutyrate (BHB) on 967 forensic cases over a two-year period was conducted. Cases were sorted into six categories of death: (i) sudden traumatic/non-natural (ST), (ii) sudden natural (SN), (iii) prolonged traumatic/non-natural (PT), (iv) prolonged natural (PN), (v) diabetic ketoacidosis (DKA), and (vi) alcoholic ketoacidosis (AKA). The mean BHB for all cases was 1.67 mmol/L (17.4 mg/dL; range: 0.11–18.02 mmol/L). The numbers of DKA, AKA, PN, PT, SN, and ST deaths were 21, 5, 155, 258, 275, and 253, respectively. Their mean vitreous BHBs were as follows: 11.04 mmol/L (DKA), 8.88 mmol/L (AKA), 1.56 mmol/L (PN), 1.55 mmol/L (PT), 1.26 mmol/L (SN), and 1.38 mmol/L (ST). There was a statistically significant difference between the mean BHBs of the PN and SN death groups (p < 0.001), as well as between those of the PT and ST death groups (p = 0.004). Given the overlapping ranges seen between the prolonged and sudden death groups, the identified differences did not hold clinical significance. In addition, we sought to determine a threshold value for vitreous BHB to definitely diagnose cases of ketoacidosis. BHB threshold concentrations between 2.5 and 5 mmol/L produced sensitivities >92% and specificities >96%. A receiver operator characteristic curve found 3.43 mmol/L to be the optimal cutoff value, demonstrating a specificity of 98.3% and a sensitivity of 96.2%. 相似文献

ABSTRACT Teacher turnover is a significant issue in education that negatively affects students’ academic performance and instructional continuity. While multiple factors impact turnover, the effects of violence directed against teachers on turnover have rarely been explored. The current study examines the extent to which (dis)empowerment applies to teachers who experienced incidents of violence and related intentions to leave their positions. The study includes 403 teachers from a national survey examining teacher-directed violence and teachers’ most upsetting experiences with violence. Using content analysis, results indicated teachers endorsed low levels of empowerment dimensions including status, autonomy and decision-making, and impact. Further, disempowerment was associated with turnover intentions and decisions. Future directions for research, practice, and policy are considered to increase empowerment and prevent turnover following incidents of violence. 相似文献

This article provides a critical next step in scholarship on climate change litigation's regulatory role. It creates a model for understanding the direct and indirect regulatory roles of this litigation. It then applies this model to the United States and Australia, two key jurisdictions for climate change lawsuits, in order to explore the regulatory pathways that this litigation has taken, is taking, and likely will take. This analysis helps to illuminate the ways in which litigation influences regulation and forms part of climate change governance. 相似文献

The disfranchisement of African Americans in the South during the late 19th century highlights the role that mass actors, in this case African Americans, can play as part of the enforcement mechanism to prevent elites from backtracking on democracy. This episode in US history further suggests that for democratic progress to be consolidated, vulnerable groups require sufficient economic and social power to defend their formal rights. Newly emancipated African Americans gained the franchise in 1870. They voted in large numbers for two decades. But at the turn of the century each Southern state introduced disfranchising measures. The article discusses the efforts of Southern political elites to restore the antebellum social and political order, and the reasons the national state failed to intervene to protect the rights of former slaves. Above all, the article explores the nature of African American resistance and its effect on the timing and course of disfranchisement. It also draws attention to the importance of African American resistance by comparing Southern disfranchisement with the little-known cases of attempted disfranchisement of African Americans in the antebellum North and early 20th century Maryland. The article concludes that the relative strength of African Americans in contemporary America makes another rollback of democratic rights unlikely. 相似文献

This paper argues that the ‘double-standard’ applied to male and female tourists’ sexual behaviour reflects and reproduces weaknesses in existing theoretical and commonsense understandings of gendered power, sexual exploitation, prostitution and sex tourism. It looks at how essentialist constructions of gender and heterosexuality blur understandings of sexual exploitation and victimhood and argues that racialized power should also be considered to explore the boundaries between commercial and non-commercial sex. This paper is based on ethnographic research on sexual–economic exchanges between tourist women and local men and boys in the informal tourist economy in Jamaica and the Dominican Republic. 相似文献

Although the systems of public schools differ among Australia, South Africa and the USA, all three countries recognize that religion plays a significant role in determining values. All three countries have written constitutions but only South Africa and the USA have a Bill of Rights that protects persons’ exercise of religious beliefs. In Australia, the place of religion in education has largely been shaped by state legislatures, administrative regulations and interpretations of the national constitution. In the USA, the long tradition of religious values being represented in public education has been severely restricted over the past 60 years, resulting in artificial judicial lines being drawn between private religious expression and government expression. However, even private expression can be prohibited if it interferes with the educational mission of a school. South Africa had a long tradition of Christian religious practices in government schools under apartheid. However, the post-apartheid 1996 Constitution and 1996 South African Schools Act still give these schools considerable latitude in investing religious values into the educational process. In Australia, values, religion and education have always been a preoccupation of those providing education, although the blurring of public and private education in Australia has resulted in a different direction for the role of religion than in the USA. 相似文献

This study examines the social-psychological factors of attributional styles, moral disengagement, and the value-expressive function of attitudes in relation to death penalty support and the robustness of that support. Respondents were first asked whether or not they supported the death penalty and were then presented several paragraphs of information exposing flaws or failures in the death penalty and asked how compelling they found the information and whether it impacted their death penalty attitudes. Results suggest that attributional style has little if any effect on death penalty support and that only a few aspects of moral disengagement seem to play a role. Value-expressiveness, on the other hand, appears to play a critical role in death penalty attitudes and support. Our findings suggest that when support is based on value-expressive foundations, it is more robust and unlikely to wane regardless of information or knowledge indicating problems with the death penalty. 相似文献
