The onset of adult offending: A neglected dimension of the criminal career

The conventional wisdom in criminology is that adult onset of offending is a rare event. Closer examination of the extant literature that use official records, however, reveals that an average of 50 percent of adult offenders initiate offending at age eighteen or older. Although criminological research has investigated late onset offending in adolescence, there is little research on adult onset offending and the correlates of adult offending. Using police contact and interview data from the 1942 and 1949 birth cohort data from Racine, WI, this study investigated the correlates of crime for adult onset and persistent offenders. The results show that employment is the only correlate to affect the probability of adult offending differently for previously delinquent and nondelinquent offenders. This article concludes by highlighting the neglect of research on adult offenders, specifically the large percentage of adult onset offenders, and calling for more research on this topic.     

轻型颅脑损伤ABR的纵向研究

目的　探索轻型颅脑损伤的电生理学指标 ,为早期临床诊断和预后判断以及法医学活体伤害鉴定提供依据。　方法　对相关病例进行脑干诱发电位 (ABR)的动态观察 ,并对结果进行统计学分析。　结果　6 0例轻型颅脑损伤患者伤后 48小时ABR的检测 ,显示主要异常表现为I-III峰间潜伏期的延长 ,说明此类损伤可造成脑干的功能紊乱。同时通过对其中 40例进行ABR追踪检测 ,结果显示大部分患者受伤三个月后脑功能状态恢复正常。　结论　轻型颅脑损伤ABR变化具有一定的特征 ,提示可作为早期临床诊断和预后判断以及法医学活体伤害鉴定的客观依据 ,应引起关注并展开进一步研究。
