Contrary to the image of college campuses as “ivory towers,” the victimization of college students recently has been portrayed as a serious problem deserving policy intervention. Based on interviews designed after the National Crime Victimization Survey, which were conducted with 3,472 randomly selected students across 12 institutions, we examined both the level and sources of students'victimization. More than one-third of the sample reported being victims during the 1993–94 academic year. Informed by the lifestyle-routine activities approach, the analysis revealed that the risk of property victimization was increased by proximity to crime, target attractiveness, exposure, and lack of guardianship. The main predictor of violent victimization was a lifestyle that included high levels of partying on campus at night and the recreational use of drugs. 相似文献

The number of deaths as a consequence of orphenadine poisoning seems to increase, mostly among severely psychotic males. The lethal dose corresponds to the weekly average dose used in the treatment of neuroleptic extrapyramidal side effects. Based on the literature, the serious, rapidly incipient, cardiac, and neurologic symptoms of poisoning are emphasized. The handing out of orphenadine to suicidal persons must be restricted, and even small overdoses (1-2 g) ought to result in the immediate initiation of observation at an intensive care unit. 相似文献

The sciatic notch/acetabular index as a discriminator of sex in European skeletal remains 总被引:1,自引:0,他引:1
The sciatic notch/acetabular index and its rule of thumb application was tested on two European skeletal series of documented sex. The results showed poor consistency between documented and estimated sex. Of the two variables comprising the index, it appeared that sciatic notch width was a particularly poor discriminator of sex. It is suggested that this may be due to differences in the relationship between sciatic notch form and body size in different ethnic groups. 相似文献

External beam proton-induced X-ray emission (PIXE) analysis has been used to verify the presence of lead in the finger bone of a murder victim. The deceased, who had been buried several years, was known to have suffered a bullet wound to his right hand several years before death. X-ray radiographs of the right second proximal phalanx revealed the possible presence of metal fragments below the surface of the bone. To verify the presence of lead in a nondestructive manner, the bone was scanned with a 1.5-MeV proton beam. PIXE analysis showed that lead was present only in the vicinity of the fragments previously detected in the radiographs. A study of gunshot residue in bone shows that the distribution of lead around the bullet hole is independent of the firing distance for distances greater than 0.6 m. 相似文献

For more than two decades, economists and sociologists have pursued parallel cross-national quantitative investigations of
the determinants of economic development. These investigations have proceeded in mutual ignorance despite the often large
overlap in statistical methods and data employed. Apparently contradictory findings have resulted, especially regarding the
impacts of international trade and foreign direct investment. We find that there are two factors that account for these inconsistent
results. One key factor is the use of different variables to measure international trade and investment, the choice of which
is in turn driven by underlying differences in theoretical motivations. A second important difference involves sociologists’
greater preoccupation with more complex multivariate models versus economists’ greater willingness to focus on individual
variables in multivariate regressions while viewing others as “controls.” A major finding of our survey is that when thesame variables are used, the results of economists and sociologists tend to be consistent, rather than contradictory (as might
have occurred, for example, because of the use of different samples of countries or time periods, or the use of other variables
included in the regression equations). We also consider some studies whose purviews go beyond economic growth to consider
factors such as income inequality, physical quality of life, demographic change, and basic needs provisioning.

Detection of cocaine metabolite in perspiration stain, menstrual bloodstain, and hair 总被引:2,自引:0,他引:2
Low nanogram and picogram quantities of cocaine metabolite equivalents were detected in extracts from perspiration stains, menstrual bloodstains, and hair using radioimmunoassay. The theory of drug inclusion in hair and its significance are discussed. 相似文献

The interpretation of bloodstain patterns at crime scenes has received increased attention in recent years. Important to an understanding of this is knowledge of the fundamentals of blood droplet formation and impact dynamics. A review of the literature reveals that a considerable amount of work has been done with aqueous drop dynamics. Workers in the forensic science area seem to have been unaware of this. In addition, some of the most important and comprehensive early work with blood droplet dynamics seems to have been forgotten. It is not cited in more recent publications dealing with bloodstain pattern interpretation. This literature is reviewed and discussed as well. The present study presents results of experiments with blood droplet dynamics and high-speed photographs of blood droplet impacts on stationary target surfaces. Some longstanding misconceptions of importance to forensic scientists engaged in crime scene reconstruction are discussed. 相似文献
