Abstract: Burial environment, in particular soil moisture, has a significant impact on the type, rate, and extent of bone degradation, which ultimately affects estimations of the postmortem interval (PMI). The purpose of this research is to determine the effects of soil moisture on the color, weight, condition, and texture of bone as it relates to the PMI. Bone changes occurring over two different time intervals (2 and 5 months) were examined using 120 sus scrofa leg bones. During each time interval bones were buried in two soil environments, one of which was drier than the other. The bones in both environments lost weight over time but the net weight loss was greater for bones in the higher moisture environment. There was no change in color, texture, or overall condition, indicating that 150 days is not long enough for such alterations to occur, regardless of the moisture level of the burial environment. 相似文献

Abstract: Literature regarding bone color is limited to determining location of primary and secondary dispositions. This research is the first to use bone color to interpret the sequence of events surrounding body disposition. Two scenarios were compared—bones buried and then exposed on the ground surface and bones exposed then buried. Forty juvenile pig humeri with minimal tissue were used in each scenario with an additional 20 controls to determine if decomposing tissue affects bone color. Munsell Color Charts were used to record bone color of surface and 2.5 cm cross‐sections. Results reveal five main surface colors attributed to soil, sun, hemolysis, decomposition, and fungi. Fungi on buried bones suggests prior surface exposure. Cross‐sections of strictly buried bones are identical to buried then exposed bone, stressing the importance of bone surface analysis. Cross‐sectioning may help verify remains have been exposed then buried. Decomposition of excess tissue creates minimal color staining. 相似文献

Although research has demonstrated connections between experiencing abuse as a child and being in a violent relationship as
an adult, the specific mechanisms through which this transmission occurs are unclear. The purpose of this study was to identify
the relationship between certain personal factors (self-appraisals and mental/substance use disorders) and experiencing violence
as an adult. Data from the National Comorbidity Survey (NCS) 1990–1992 were utilized. Respondents who reported experiencing
childhood abuse or victimization and were in a current intimate partnership (N = 590) were selected for analysis. Multivariate logistic regression indicated that low self-esteem, past year PTSD, and past
year alcohol dependence were significantly associated with intimate partner violence after controlling for other self-appraisals
and mental disorders. 相似文献

Since 1989, federal law requires states to have presumptive child support guidelines and review them using economic data on child-rearing costs at least once every 4 years. This article reviews the child support guidelines models adopted by states, how they relate to estimates of child-rearing expenditures, the extent that states are updating their guidelines, and some of the more controversial guidelines provisions (i.e., adjustments for shared-parenting time, additional dependent children, and low-income nonresidential parents). We find that many states are not updating their core formulas and schedules. As a result, several state guidelines produce support award amounts that are below the costs of raising children. 相似文献

This study prospectively evaluated perpetrator risk factors for sexual assault perpetration, including peer influences, beliefs and attitudes about sexuality, alcohol use, and token resistance. Perpetration of sexual assault was evaluated at three time periods: pretest, 3-month follow-up, and 7-month follow-up. Retrospective and prospective analyses yielded differential predictors of sexually aggressive behavior. However, perpetration of sexual assault at any particular assessment period was a predictor of perpetration during the subsequent follow-up period. Furthermore, several variables that have previously been demonstrated in the literature to be related to the perpetration of sexual assault were not significant in regression analyses, indicating that these variables may be rendered insignificant when accounting for past perpetration in prospective analyses. These findings may have significant potential impact on development of sexual assault prevention programming with men. 相似文献
