Gottfredson and Hirschi (A General Theory of Crime, Stanford University Press, Stanford, CA, 1990) have proposed a general theory of crime to explain a set of behaviors they refer to as acts of force and fraud. Central to their theory is the claim that force and fraud are both manifestations of the individual's unrestrained pursuit of short-term gratification. At the same time, research from numerous disciplines suggests that the correlates of violence differ somewhat from those of property crime. The present study therefore uses data from the National Youth Survey to explore whether force and fraud can legitimately be viewed as manifestations of a single underlying construct among American adolescents. Overall, findings from confirmatory factor analyses suggest that they cannot. Rather, they suggest that multi-factor models of force and fraud improve significantly upon the fit of single-factor models and that force and fraud may therefore reflect overlapping, but empirically distinct, constructs. 相似文献

Allele frequencies for 09 STR autosomal loci (D3S1358, D5S818, D7S820, D8S1179, D13S317, D18S51, D21S11, FGA and VWA) included in the AmpFlSTR Profiler Plus were obtained from a sample of unrelated individuals from Rio Grande do Sul (southern Brazil). 相似文献

The recent global rush for farmland in Latin America has produced a dramatic increase in the level of foreign investment in land in Brazil. The current trend accentuates the ongoing process of foreignization of agriculture associated with the production of grains, sugar, ethanol and other commodities, increasing land prices. In response, the Brazilian government reestablished a legal mechanism for ‘controlling’ land-based foreign investment which has proven neither efficient nor effective in solving land concentration. This paper examines this issue by analyzing the causes of the increase in investment as well as the consequences of this process with respect to land prices, critically situating land-based investments and the government's policy response in a broader discussion of the demands of agrarian social movements. 相似文献

Stutter products generated during DNA amplification by the polymerase chain reaction (PCR) may complicate mixture interpretation. The PCR amplification of the DYS392 locus typically results in three distinct detectable PCR products: the true allele product (N), a stutter product three bases smaller (N-3), and a reproducible low-level product, three bases larger (N+3). Sequence analysis of the N+3 product demonstrated that its sequence is one TAT repeat longer than the true allele product. Our experiments demonstrated that the quantity of both N-3 and N+3 stutter increased as the allele number increased. The percent stutter also increased as the magnesium concentration was increased in the reaction, as well as when the amount of input DNA was decreased. As both stutter products behave in a similar and reproducible fashion, the same rules that apply to the interpretation of N-3 stutter products in short tandem repeat analysis, can be applied to N+3 stutters. The characterization of the DYS392 N+3 product is the first detailed published study of a stutter product larger than the true allele. 相似文献

Using data from a new household survey on environmental attitudes, behaviors, and policy preferences, we find that current weather conditions affect preferences for environmental regulation. Individuals who have recently experienced extreme weather (heat waves or droughts) are more likely to support laws to protect the environment. We find evidence that the channel through which weather conditions affect policy preference is via perceptions of the importance of the issue of global warming. Furthermore, environmentalists and individuals who consult more sources of news are less likely to have their attitudes toward global warming changed by current weather conditions. These findings suggest that communication and education emphasizing consequences of climate change salient to the individual's circumstances may be the most effective in changing attitudes of those least likely to support proenvironment policy. In addition, the timing of policy introduction could influence its success. 相似文献

Legal socialization theory predicts that attitudes mediate the relation between legal reasoning and rule-violating behavior
[Cohn, E. S., & White, S. O. (1990). Legal Socialization: A Study of Norms and Rules. New York: Springer-Verlag]. Moral development theory predicts that moral reasoning predicts rule-violating behavior directly
as well as indirectly [Blasi, A. (1980). Bridging moral cognition and moral action: A critical review of the literature. Psychological Bulletin, 88, 1–45]. We present and test an integrated model of rule-violating behavior drawing on both theories in a longitudinal study
of middle school and high school students. Students completed questionnaires three times during the course of 1 year at 6-month
intervals. Legal and moral reasoning, legal attitudes, and rule-violating behavior were measured at times one, two, and three
respectively. Structural equation models revealed that while moral and legal reasoning were directly and indirectly related
to rule-violating behavior among high school students, legal reasoning bore no direct relation to rule-violating behavior
among middle school students. The implications for an integrated model of reasoning and rule-violating behavior are discussed. 相似文献
