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 AIDS Risk Reduction Model (ARRM) is a conceptual model designed to explain the influence of knowledge and attitudes about AIDS/HIV on risk-related behaviors. This article measures the influence of the primary concepts associated with the ARRM (labeling, commitment, and enactment) on high-risk adolescent's knowledge, attitudes, and self-reported behaviors. Data were collected from 393 adolescents incarcerated in juvenile detention facilities. Ordered probit and ordinary least squares (OLS) analyses were conducted to determine which of several independent variables have the most impact on acceptance of the ARRM. Results indicated that the ARRM is effective for understanding the factors that influence AIDS risk avoidance. Findings also indicate that previous life experiences should be formally integrated into the model. Moreover, specific forms of enactment are associated with different factors. Suggestions as to how the ARRM may prove useful for promoting behavioral change among high-risk adolescents are provided. 相似文献

Around the world and especially in English-speaking countries there has been a wave of contract-based public sector management following on the heels of a wave of corporatisation and privatisation. 相似文献
