Homicide by starvation is a very rare occurrence, especially when the victim is ambulant. This paper presents a case where the death of the individual went undiscovered for more than 3 weeks. A successful conviction for murder ensued. The paper also discusses social and pathological problems associated with this crime. 相似文献

We examined the relation between personality traits and crime in two studies. In New Zealand we studied 18-year-old males and females from an entire birth cohort. In Pittsburgh we studied an ethnically diverse group of 12- and 13-year-old boys. In both studies we gathered multiple and independent measures of personality and delinquent involvement. The personality correlates of delinquency were robust in different nations, in different age cohorts, across gender, and across race: greater delinquent participation was associated with a personality configuration characterized by high Negative Emotionality and weak Constraint. We suggest that when Negative Emotionality (the tendency to experience aversive affective states) is accompanied by weak Constraint (difficulty in impulse control), negative emotions may be translated more readily into antisocial acts. We review additional evidence about the developmental origins and consequences of this personality configuration and discuss its implications for theories about antisocial behavior. 相似文献

Structural change is endemic in the Eastern European economies and the newly emerging Commonwealth of Independent States yet conventional econometric modelling techniques proceed under the assumption that there is a structurally stable ‘true’ economy to be discovered. This paper extends the analysis of Hall (1993) by exploring the consequences of endemic structural change for forecasting and building structural econometric models. We propose a model formulation which makes the econometric model itself able to adjust its parameters in the light of economic change using the Kalman Filter. The paper then illustrates this approach by building a small model of Romania and investigating its forecasting properties. 相似文献

This study examines trends in the distribution of gross earnings in Hungary since 1988, using official household budget surveys and enterprise-based earnings surveys. We find a significant growth in inequality since 1988, to levels comparable with western Europe. There is little evidence of a serious discrepancy between the two data sources used. 相似文献
