A "thermic law" postulating a relationship between violent crime and hot weather or southern climates is one of the oldest propositions in criminology. On the question of homicide and seasonality, modern research produces contradictory findings—some studies support a seasonal pattern of homicide but others reject such a pattern. A review of studies on the seasonality of homicide and an analysis of Uniform Crime Reports data and data on homicide in Baltimore from 1974 to 1984 are undertaken in order to resolve the issue. The contradictory results are not explained by differences in definitions nor by differences in data or methodology; nor are they explained on the bases of regional differences or an urban bias present in most studies. The nature of the question asked, however, is critical to the results obtained. The conclusion reached is that there is no season to homicide. The months of December, July, and August are significantly more likely to be among the months in which homicide is high for any given year, but the number of homicides during those months may not be significantly higher than in other months. 相似文献

J. P. Rushton has done research indicating that predominantly black nations have higher rates of violent crime than predominantly white nations, which have higher rates than predominantly Asian nations. He attributes these differences to constitutional, inheritable factors on which the races vary. This article discusses the numerous problems with Rushton's use of international crime data and analysis, foremost of which are his use of one-way analysis of variance and lack of consideration of other causes of variation. Regression analysis-including dummy race variables and other relevant explanatory variables-indicates no significant association between race and cross-national homicide rates, the best and probably only valid indicator of cross-national variation in violent crime. This is the case whether reanalyzing Rush-ton's data or analyzing properly adjusted, inspected, and selected homicide rates. 相似文献
