The changing of the guard: Top management characteristics, organizational strain, and antitrust offending

From within an organizational strain perspective, this paper examines the effects of managerial succession, CEO background, decentralized management, and product dominant strategies on the reported corporate antitrust offending levels of 43 basic manufacturing companies over a 22-year period. In the aggregate, findings suggest that past illegal involvement predicts future offending; companies headed by finance and administrative CEOs have higher offending levels than do firms headed by CEOs from other backgrounds; a turnover in top management generally decreases offending levels; the pursuit of product dominant strategies increases the number of anticompetitive acts; and offending levels are unrelated to whether new leaders are recruited from within or outside the firm, whether the CEO is also Chair of the Board of Directors, or whether management is centralized or decentralized. The effects of some variables on corporate offending interact with firm performance.     

用乙醇和正丁醇判断豚鼠溺死时间的实验探索

本文以豚鼠为实验动物，溺死后浸泡于水温为２０℃的水缸小。运用气相色谱法测定其溺死后不同浸泡时间在心、肺、肝小＃在的乙醇和正了醇含量。实验结果表明在溺死后８天内，样本中乙醇和正了醇量随浸泡时间的延长而增加，且呈高度的直线相关。其血、肺、矸中乙醇量与溺死时间的回归方程依次为ｙ１＝－１６．８２＋１２．９５Ｘ，ｙ２＝－５８．５３＋１９．２３Ｘ，ｙ３＝－３１．９１＋４７．２９Ｘ。血、肺、肝小正丁醇量与溺死时间的回归方程依次为ｙ４＝－１０．１３＋５．８６ｘ，ｙ５＝－２９．４５＋１６．１７ｘ，ｙ６＝３．７５＋１４．３１ｘ。综合分析溺死后血、肺、肝小乙醇和正丁醇，有可能作为判断溺死时间的新指标。     

Peer pressure and adolescent substance use

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida.

The determination of cocaine in hair: a review

The explosion of literature related to the analysis of hair for cocaine and its products is reviewed. In the commonly accepted applications of hair testing for cocaine, those related to criminal or civil investigations and pharmacotoxicologic studies occupy most of the relevant published work. This review uses detailed, ‘binary’ (yes/no) tables to demonstrate trends in the literature, and allows researchers and caseworkers quick access to the literature most important for answering a variety of questions.     

Delay reduction in the federal courts: Rule 50(b) and the Federal Speedy Trial Act of 1974

During the 1970s, 94 federal district courts implemented two major policy initiatives, Rule 50(b) of theFederal Rules of Criminal Procedure and the Federal Speedy Trial Act, that were designed in Washington to combat delay in the processing of federal criminal cases. Both of these initiatives established a national priority of delay reduction in criminal cases, encouraged local district court planning for delay reduction; established reporting procedures for monitoring local compliance, and provided for the determination of quantitative goals for the time to disposition of criminal cases. Neither initiative mandated specific activities for delay reduction; this determination was left to the discretion of local federal district courts. This research examines the effectiveness of Rule 50(b) and the Speedy Trial Act by constructing a 150-month time series of three measures of case processing time. A multiple-intervention time-series model found that both of these initiatives contributed to the dramatic reduction in the time to disposition in federal criminal cases. These effects persisted after controls for changes in case characteristics and judicial resources were introduced.Points of view expressed in this research are those of the author and do not necessarily represent the official position of the U.S. Department of Justice.
