Protophormia terraenovae (Robineau‐Desvoidy) (Diptera: Calliphoridae) and Phormia regina (Meigen) (Diptera: Calliphoridae) are morphologically similar blow fly species commonly used for estimating postmortem intervals. Field collection and storage of adults can result in color changes, in particular on calypters and palps; often collected specimens show damage such as wing fray or fungal growth. We measured the frons width: total head width ratio using photographs (ImageJ version 1.49) to differentiate these two species. Both sexes were distinguishable to species, with the greatest difference between males: 12.34% P. terraenovae versus 1.62% P. regina, less so for females: 40.25% P. terraenovae, versus 33.65% P. regina. Incorporating this feature into future blow fly keys would help with distinguishing field‐caught specimens when other features are obstructed. 相似文献

Bullying in secondary schools is a serious concern for educators and parents. The relationship between bullying and school climate has been identified and strategies to improve school climate are available. The importance of leadership in shaping school climate has been well documented. This exploratory study explores the role of leadership in implementing an approach to school climate change (positive behavior intervention and supports) in comprehensive Southwestern high schools participating in a federal school safety grant. Leadership involvement in the change process appears to be a key component leading to student-reported behavior change. Our findings suggest that although changes in school climate should lead to changes in bullying behaviors, the opposite is the case. Implications for practice and further research are discussed. 相似文献

The U.S. Supreme Court's recent revival of state sovereign immunityis usually cited as a significant development in modern U.S.federalism. These decisions giving states a powerful defenseagainst lawsuits lead to the question: How will the states reactto the Court's rulings? How likely is it that states will consentto be sued? This article discusses the consequences of the Court'ssovereign immunity rulings specifically concerning state legislativedebates over immunity waiver bills. It explains why some stateshave been willing to waive immunity, despite the Court majority'sfears of a flood of lawsuits if states did not enjoy immunity. 相似文献

Over the past decade, much has been written about the results of reinventing government. Most research has examined the effects of executive or managerial perspectives. Using David Rosenbloom's competing perspectives model, we examine Medicaid managed care programs for children with special health care needs to illustrate the influence of legislative and judicial institutional perspectives on the reinvention movement. Legislative and judicial responses to the reinvention of Medicaid managed care reveal the outer limits of what managed care and related executive reforms can accomplish in a Constitutional system that is based on checks and balances among competing institutional perspectives. Furthermore, relative to Medicaid managed care, legislative and judicial responses conserve public responsibility to society's most vulnerable populations. In the long run, the balance of institutional perspectives and values—not managerial innovation per se—will influence public administration. 相似文献
