Investigating the Potential of Fluorescent Fingerprint Powders as a Marker for Blow Fly Larvae (Diptera: Calliphoridae) 下载免费PDF全文
Jennifer Y. Rosati Ph.D. Scott D. Robinson B.Sc. Richard Devine 《Journal of forensic sciences》2015,60(3):653-658
Four fluorescent fingerprint powders (RedWop?, GreenWop?, Basic Yellow?, and Yellow Powder?) were evaluated as a marker for blow fly larvae. Administration methods included ingestion (high vs. low concentration) or topical. Ingestion of high concentrations of Basic Yellow? and RedWop? caused higher larval mortality. Basic Yellow? delayed development and adult emergence while RedWop? and Yellow Powder? had a significant effect on particular stages of development, however, emergence time was not altered. Optimal administration is through ingestion at low concentration levels (<10%) or topically, with GreenWop? demonstrating minimal adverse effects. Optimum wavelength for discrimination between powders was 450 nm. This research can aid in investigative training to increase visibility of larval and pupal blow flies. It can also be used in entomological studies to differentiate between larval blow flies (or other dipteran) species or individuals to further understand complex interactions and behavior during larval development. 相似文献

The complexity of the modern information ecosystem raises many questions for public organizations. In the context of emergency management, information (such as warning messages) is communicated not only from a source of authority to the public but also between members of the public. The authors use a series of storms that affected Oklahoma in the spring of 2016 to test propositions related to how information about tornado warnings reached the public and who received and shared information about the storm, as well as to identify how gender and age mediate the influence that exposure to an extreme weather event has on the sharing of this information. Overall, the authors find that reported exposure to a tornado increases information sharing through a variety of media and technology. The effect of the tornado erases the otherwise present gender gap in sharing information, while it has little effect on the media platforms that are most popular among older respondents. 相似文献

Physicians use the American Medical Association's Guides to the Evaluation of Permanent Impairment, 5th edition to evaluate millions of disability applicants each year. As major contributors to the chapter in the Guides devoted to assessing impairment associated with pain, we confronted the difficulties of incorporating pain into the Guides' overall evaluation system. Analysis of these difficulties is complicated by the paucity of research on the Guides, and by ambiguities and contradictions that pervade it. We propose that the ambiguities can be reduced if impairment is consistently defined in terms of organ or body part derangement, and disability in terms of activity limitations at the level of the whole person. We also propose a distinction between objective factors that may influence a person's ability to perform activities following injury. We suggest that when physicians examine disability applicants, they should evaluate both objective measures of organ or body part dysfunction and subjective reports of applicants -- especially ones regarding pain. We conclude that a comprehensive medical evaluation of disability applicant encompasses more than an impairment assessment. 相似文献

Mock jurors were permitted to take notes during a trial simulation and to have those notes available during an individualized test of recall. Compared to non-notetakers, those who took notes showed superior recall and were more involved in the trial proceedings. The quantity of notes taken, their accuracy, and their organization all correlated positively with accuracy of recall. 相似文献
