Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications. 相似文献

Dwight Waldo's conception of the politics–administration question might be better understood as a "relationship" that contains elements of separation and intermixture rather than a "dichotomy," according to this author-commentator.To suggest that Waldo came to support the dichotomy presumes agreement about the meaning of the concept that is missing in Waldo's writings and in the public administration literature. 相似文献

Environmental samples from indoor surfaces can be confounded by dust, which is composed largely of human skin cells and has been documented to contain roughly tens of micrograms of total DNA per gram of dust. This study complements previous published work by providing estimates of the quantity of amplifiable human DNA found in environmental samples from a typical indoor environment, categorized by the intensity of human traffic and visible quantity of dust. Dust was collected by surface swabbing standard 576 cm2 areas in eight locations, and evaluated for total DNA quantity, presence of human DNA (mitochondrial and nuclear loci using conventional PCR), quantity of human nuclear DNA using quantitative PCR, and STR analysis. The total DNA content of 36 dust samples ranged from 9 to 28 ng/cm2, and contained 0.2–1.1 pg/cm2 of human DNA. Overall, human DNA was detected in 97% of 36 dust samples and 61% of samples yielded allele distributions of varying degrees of complexity when subjected to STR analysis. The implications of this study are twofold. First, the presence of dust in evidence can be a significant contamination source in forensic investigations because the human DNA component is of sufficient quality and quantity to produce allele calls in STR analysis. This can be effectively managed by implementing stringent protocols for collection and analysis of potential biological samples. A second implication is the use of dust as a source of evidence for identification of inhabitants within a defined location. In the latter case, a number of additional studies would be necessary to identify relevant pretreatments for environmental dust samples and to develop the necessary deconvolution techniques to separate the composite genotypes obtained. 相似文献

A meta-analysis investigating the relationship between marital satisfaction/discord and intimate partner violence (IPV) in
heterosexual relationships was conducted with 32 articles. Overall, a small-to-moderate effect size (r = −0.27) indicated a significant and negative relationship existed between marital satisfaction/discord and IPV. Moderator
analyses found no differences between effect size based on construct examined (discord or satisfaction). However, the magnitudes
of observed effect sizes were influenced by other moderator variables, including the use of standardized versus non-standardized
measures, gender of the offender and victim, role in the violence (perpetrator versus victim), and sample type (clinical versus
community). The data suggests that gender is an especially important moderator variable in understanding the relationship
between marital satisfaction/discord and IPV. 相似文献
