Accurate prediction of the postmortem interval requires an understanding of the decomposition process and the factors acting upon it. A controlled experiment, over 60 days at an outdoor site in the northwest of England, used 20 freshly killed pigs (Sus scrofa) as human analogues to study decomposition rate and pattern. Ten pigs were hung off the ground and ten placed on the surface. Observed differences in the decomposition pattern required a new decomposition scoring scale to be produced for the hanging pigs to enable comparisons with the surface pigs. The difference in the rate of decomposition between hanging and surface pigs was statistically significant (p = 0.001). Hanging pigs reached advanced decomposition stages sooner, but lagged behind during the early stages. This delay is believed to result from lower variety and quantity of insects, due to restricted beetle access to the aerial carcass, and/or writhing maggots falling from the carcass.  相似文献

An examination of self-report scales of 160 men and 76 of their partners or former partners found significant correlations between jealousy and abusiveness (for coupled dyads) or intrusiveness (for separated dyads). Jealousy was related to borderline personality and to MCMI-II measures of Post Traumatic Stress Disorder. Rejection sensitivity leading to pathological acts, such as abusiveness and intrusiveness, is seen as originating in early insecure attachment and exposure to shaming experiences.  相似文献

Extending from the organizing crime perspective, we study how legitimate world actors contribute to structuring a criminal network. This focus also underscores the facilitating role that some participants have in criminal settings. Based on a case study of an illegal drug importation network that was monitored by law-enforcement investigators over a two-year period, we find that although most legitimate actors (or non-traffickers) had nominal roles and contributed minimally to the criminal network's structure, a minority of these actors were critical to the network in two ways: (1) they were active in bringing other participants (including traffickers) into the network; and (2) they were influential directors of relationships with both non-traffickers and traffickers. The presence of such influential participants from legitimate occupational settings illustrates how upperworld figures can facilitate criminal enterprise beyond the mere contributions of legitimate status and expertise.  相似文献

In this article a middle class adolescent peer group is studied in a community setting using ethnographic techniques. The purpose of the study is to describe the group's relationship to adults and to uncover the adult reference group after which the group modeled itself. Although this group was organized to help poor people in the United States and abroad and had extensive contact with adults who could be described as change agents working to close the economic gap between rich and poor, this group modeled itself after middle class adult managers. The youths were attracted to the change agent adults only in so far as they satisfied their desire for equal status interaction with adults. Attempts by the group to establish closer contact with their adult models were in conflict with their desire to maintain autonomy from adult domination. The concluding section compares the findings of this study to two ethnographic studies of adolescent groups that used secondary school sites.Received her Ph.D. from Northwestern University. Main research interest is applying ethnographic techniques to the study of educational process. Currently studying the urban principalship with a grant from the Spencer Foundation.  相似文献

Survey reports of police stops and driving behavior are a potential methodology for examining the magnitude and prevalence of the “Driving While Black” phenomena. However, estimates of the magnitude or correlates of racial disparity in police stops from self-reported survey data are potentially compromised if the accuracy of self-reports of police stops and driving behavior differ by race. We report on the results of a reverse record check survey in which we directly assess the degree and consequences of differences by race in self-reports of police stops. In our sample of drivers who had been cited for speeding in the preceding year, we found that 77% of the White respondents and 71% of the African American respondents admitted to being stopped. While both groups underreport stops, African Americans do so at a higher rate. This finding is consistent with many past studies which report stronger social desirability effects on survey responses among African Americans. Thus, survey data will tend to underestimate the magnitude of the “Driving While Black” phenomena.
