The peer context is a central focus in research on adolescent risk behaviors but few studies have investigated the role of the peer context in the perpetration of adolescent dating violence. This longitudinal study examined between-subjects and within-person contemporaneous and lagged effects of peer attributes, measured with social network analyses, on trajectories of dating violence perpetration and determined if effects varied by grade and/or sex of the adolescent. Data are from adolescents who participated in a five-wave panel study beginning when they were in 7 through 9th grade and ending when they were in 10 through 12th grade (n = 3,412); half were male, 40.5 % were white, 49.9 % were black and 10.4 % were of another race/ethnicity. Significant between-subjects effects indicate that adolescents who typically have friends who use dating violence, and girls who are typically high in social status, are at increased risk for using dating violence throughout adolescence. Adolescents who typically have high quality friendships and girls who typically have friends with pro-social beliefs are at decreased risk for using dating violence throughout adolescence. Significant within-person contemporaneous effects indicate that both boys and girls reported lower levels of dating violence than usual at times when they had more friends with pro-social beliefs, and reported higher levels of dating violence than usual at times when they had higher social status. None of the lagged effects were significant and none of the effects varied across grade. These findings suggest that the peer context plays an important role in the development of the perpetration of adolescent dating violence. 相似文献

This article examines the preliminary findings of an oral history project on women's working lives in three Irish counties in the period 1936-1960. By employing a feminist analysis of the narratives, the authors endeavour to investigate the extent to which the reality of married women's working lives corresponded with the rhetoric of Irish womanhood generated by political and religious discourses of the day. The analysis reveals that while the women did accept the home-based motherhood role prescribed for them, in many cases financial necessity dictated that they combine this role with that of part-time and in some cases, full-time participation in the labour market. 相似文献

Technology‐based economic development programs have become a salient feature of the state policy landscape since the 1980s. While much research exists on the topic, little attention has been given to the processes of policy formation. State programs have moved towards high technology areas emphasized at the federal level over the past decades, and nanotechnology became one of the latest targets. This paper examines the eight‐year process through which Pennsylvania adopted a “state‐wide strategy,” culminating in the Pennsylvania Initiative for Nanotechnology. In this process, programs that responded to the interests of multiple agents came first, and a state policy was formulated after the fact. This pattern of “rationalized policy formation,” as opposed to rational policy formation, may be more common than suspected. Its strengths and weaknesses in this Pennsylvania case are discussed. 相似文献

Parties willing to engage in cross-ethnic political cooperation are essential for the stability and democracy of ethnically divided post-conflict states. The investigation of voting in Macedonia and Bosnia, which are similarly small, impoverished, ethnically fragmented and threatened states that arose out of Yugoslavia, helps uncover factors that encourage voters to support parties willing to engage in cooperative multiethnic governance. Analysis of survey data suggests that supporters of the non-nationalist challengers in the first post-violence elections expressed both strong positive associations with the past communist system and clear negative assessments of the governing record of the incumbent nationalists, sentiments that were stronger among Macedonians than among Bosniaks. Data, however, call into question popular contentions that voters' support for non-nationalists is rooted in their social tolerance or engagement in civil society. The finding that Macedonian support for non-nationalist parties is partly due to negative voting combines with difficult domestic social and economic conditions, unfriendly neighbours and uncertain regional integration processes to suggest continuing challenges for Macedonia. 相似文献

The National Institute of Forensic Toxicology, Oslo, receives blood and urine samples from all Norwegian drivers apprehended on suspicion of driving under the influence of alcohol or drugs. In 1983 we received samples from 1446 drug-suspected drivers, out of which 445 underwent toxicological analysis. The drugs found most frequently were tetrahydrocannabinol (THC) (n = 199), diazepam (n = 166) and amphetamine (n = 102). A cautious interpretation of the data indicate that about 200 of the 445 subjects selected for toxicological analysis drove under severe influence of drugs. Because of the high percentage of submitted cases not analysed for drugs, this figure represents a minimum estimate. Compared with the results from 1978, we found a several-fold increase in detections of THC and amphetamine in 1983. The number of diazepam detections did not increase in a similar way, but we estimated that the diazepam detections would have increased 3-fold if we had analysed as frequent for this drug in 1983 as in 1978. 相似文献

Classification system of frontal sinus patterns by radiography. Its application to identification of unknown skeletal remains 总被引:4,自引:0,他引:4
Frontal sinuses of Japanese skulls were radiographically examined from the view point of identifying individuals. The system of classification of sinus was proposed, basing on the area size, the bilateral asymmetry, the superiority of side, the outline of upper borders, the partial septa and the supraorbital cells. Frontal sinus patterns could be divided into above 20,000 possible combinations by combining the class numbers in each classification item described above. The frontal sinus pattern of a given person was formulated as a code number which was determined by arranging the class numbers in each classification item as serial numbers. This identification system by the frontal sinus pattern should allow one to characterize each person. The application of this identification system to an actual criminal case was also described. 相似文献

Detection of diatoms in blood by a combination of membrane filtering and chemical digestion 总被引:2,自引:0,他引:2
An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically. 相似文献

A series of fatal motorcycle accidents from a 7-year period (1977-1983) has been analyzed. Of the fatalities 30 were operators of the motorcycle, 11 pillion passengers and 8 counterparts. Of 41 operators 37% were sober at the time of accident, 66% had measurable blood alcohol concentration (BAC); 59% above 0.08%. In all cases where a pillion passenger was killed, the operator of the motorcycle had a BAC greater than 0.08%. Of the killed counterparts 2 were non-intoxicated, 2 had a BAC greater than 0.08%, and 4 were not tested. The results advocate that the law should restrict alcohol consumption by pillion passengers as well as by the motorcycle operator. Suggestions made to extend the data base needed for developing appropriate alcohol countermeasures by collecting sociodemographic data on drivers killed or seriously injured should be supported. 相似文献
