Steroid Use and School Violence,School Violent Victimization,and Suicidal Ideation Among Adolescents
Rebecca L. Elkins Keith King Laura Nabors Rebecca Vidourek 《Journal of school violence》2017,16(4):399-410
School violence, school violent victimization, and suicidal ideation among adolescents are serious public health concerns. This pilot study investigated the influence of steroid use on problem behaviors. Secondary data analyses of the 2014 PRIDE Questionnaire were performed based on information collected from 38,414 high school adolescents. Results indicated high rates of school violence, school violent victimization, and suicidal ideation. Steroid use was directly related to all three problem behaviors. Results varied based on sex, race, grade level, and ethnicity. Health professionals, schools, and prevention specialists may benefit from the findings of this study. Examination of other factors related to steroid use in relation to the aforementioned problem behaviors is imperative. 相似文献

Mitochondrial DNA Profiling of Illegal Tortoiseshell Products Derived from Hawksbill Sea Turtles

The hawksbill sea turtle (Eretmochelys imbricata) is a highly endangered species, commonly poached for its ornate shell. “Tortoiseshell” products made from the shell are widely, although illegally, available in many countries. Hawksbills have a circumglobal distribution; thus, determining their origin is difficult, although genetic differences exist geographically. In the research presented, a procedure was developed to extract and amplify mitochondrial DNA from tortoiseshell items, in an effort to better understand where the species is being poached. Confiscated tortoiseshell items were obtained from the U.S. Fish and Wildlife Service, and DNA from 56 of them was analyzed. Multiple mitochondrial haplotypes were identified, including five not previously reported. Only one tortoiseshell item proved to be of Atlantic origin, while all others corresponded to genetic stocks in the Indo‐Pacific region. The developed methodology allows for unique, and previously unattainable, genetic information on the illegal poaching of sea turtles for the decorative tortoiseshell trade. 相似文献

Subcutaneous bruises caused by blunt injury are common findings in medicolegal case work. If the hematoma involves the anterior thoracic wall, bruises are mostly absent in the region of the nipples and the surrounding areola. A similar phenomenon has already been described for hypostatic skin hemorrhages. A possible explanation for both phenomena is the special tissue texture in the nipple–areola complex. Based on four cases from the forensic autopsy material and two cases from clinical forensic examinations, the macromorphological findings and the histological correlates are presented. 相似文献

During World War II, German naval codebreakers in the B-Dienst made extensive breaks into Naval Cypher No. 3, an enciphered code used by the Allies for the vital Atlantic convoys. It is often suggested that they did not discover that Cypher No. 3 was insecure until May 1943. This article shows that the British had learned about this much earlier, in August 1942, and that they informed the US Navy then. British solutions of messages encrypted with the Wehrmacht's Tunny teleprinter cipher machine had revealed that the B-Dienst was solving Naval Cyphers Nos. 3 and 4. Surprisingly, those ciphers were not replaced until June 1943. 相似文献

This article introduces the new Australian Alcohol Advertising Review Board (AARB) Code and assesses television advertising practices against its advertising content provisions. The Code is administered by independent experts to provide an alternative to the industry‐led Alcohol Beverages Advertising Code Scheme that has attracted substantial criticism. The new Code aims to balance the alcohol industry's right to promote a legal product against critical protections for young people and public health. To assess whether the new Code will require substantial changes to alcohol advertising practices, a content analysis was conducted of alcohol advertisements aired prior to its introduction on all four free‐to‐air commercial television channels over two months. A majority of the analysed advertisements (48 of 64) contained at least one element that could be construed as a breach of the AARB Code. The largest numbers of potential breaches were for the provisions relating to the association of alcohol with success and using appeals that are likely to be attractive to young people. The results demonstrate that the Australian alcohol industry will need to reassess current advertising practices to achieve compliance with the new Code. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The presence of a sizeable expatriate African population constitutes a potentially exploitable, if undeveloped, resource that represents a significant developmental challenge for the continent. Problematically the global division of labour and power, as well as differences of region, class, generation, ethnicity and race, are not properly recognised within the existing scholarship or development policy. What is clear is that diasporas do have a substantial role to play in development on the African continent. Further theoretical and empirical investigation is necessary to investigate the practical significance, nature and content of diasporic identifications and activities. By setting these against the structural backdrop of the global economy and the closely associated ideology of globalisation, this paper seeks to provide a new basis for understanding the role of the diaspora in development. This has considerable policy implications as to which diasporic populations should be targeted for developmental purposes. 相似文献

Abstract While the pages of Criminal Justice Matters frequently examine and assess criminal justice policies and often make recommendations on how to reform the system, this edition takes a more reflexive approach. Rather than focus on the nature of criminal justice reforms, this issue of cjm shines a spotlight on the reformers. 相似文献
