Few studies compared oral fluid (OF) analysis to laboratory urinalysis (UA) in real-world criminal justice environments, and no studies had collected survey data, from either specimen providers or specimen collectors, about the overall OF collection experience. In the most comprehensive toxicological comparison study conducted to date, urine and OF specimens were collected from a sample of 223 adult probationers in Baltimore City, Maryland, between March and May 2004. In addition, probationers and probation staff were surveyed about the OF collection experience. With confirmed UA as the reference standard, the Intercept Oral Specimen Collection Device® (Intercept) was 100 percent sensitive and 99 percent specific for benzodiazepines, 92 percent sensitive and 96 percent specific for cocaine, 77 percent sensitive and 96 percent specific for opiates, 39 percent sensitive and 98 percent specific for marijuana, and 75 percent sensitive and 91 percent specific for the detection of at least one drug. Seventy-two percent of the probationers and 88 percent of the probation staff rated the Intercept experience better than the collection of urine specimens. Implications for criminal justice policy and research are discussed.  相似文献

Abstract: The purpose of this study was to outline a method by which an antemortem photograph of a victim can be critically compared with a postmortem photograph in an effort to facilitate the identification process. Ten subjects, between 27 and 55 years old provided historical pictures of themselves exhibiting a broad smile showing anterior teeth to some extent (a grin). These photos were termed “antemortem” for the purpose of the study. A digital camera was used to take a current photo of each subject’s grin. These photos represented the “postmortem” images. A single subject’s “postmortem” photo set was randomly selected to be the “unknown victim.” These combined data of the unknown and the 10 antemortem subjects were digitally stored and, using Adobe Photoshop software, the images were sized and oriented for comparative analysis. The goal was to devise a technique that could facilitate the accurate determination of which “antemortem” subject was the “unknown.” The generation of antemortem digital overlays of the teeth visible in a grin and the comparison of those overlays to the images of the postmortem dentition is the foundation of the technique. The comparisons made using the GrinLine Identification Technique may assist medical examiners and coroners in making identifications or exclusions.  相似文献

试论协同型民事诉讼模式的建立   总被引:36,自引:3,他引:33  
本文侧重论述了未来民事诉讼模式的建立问题。文章认为,长期的职权主义或超职权主义现象应当结束。根据中国的国情、民事诉讼与生俱来的社会公益性以及各国改革的经验,未来的民事诉讼不应该是纯粹当事人主义而应该是协同型民事诉讼模式。  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

This study examined the intergenerational transmission of aggression across three generations in 181 community families. Regression analyses were conducted to assess the extent to which child abuse and marital abuse in the family-of-origin (G1) are predictive of child abuse potential and marital aggression in the second generation (G2), abuse in the family-of-origin is predictive of aggression in the third generation (G3), and child abuse potential and marital aggression in the second generation are predictive of aggression in the third generation. For males, exposure to aggression was predictive of aggressive behavior across all three generations. For females, the only significant prediction was from marital aggression in G1 to husband-to-wife marital aggression in G2. This study points to the importance of examining the transmission of both child abuse and marital aggression in order to assess their relative importance. It is also recommended that the transmission of aggression be assessed separately for males and females, as the data point to the family system as a factor related to aggression in males, yet do not provide the same explanation for females.  相似文献

Taiwan is known for rapid economic growth, but in 1988, the government ended 40 years of martial law, resulting in greater political and social freedoms. This paper explores the influence of economic, social, and political structures on crime in the Republic of China on Taiwan. A time series analysis examines the structural correlates of crime in Taiwan from 1964 to 1990. Both total crime and burglary/larceny rates are regressed on seven independent variables derived from various theoretical perspectives. The results support Hagan's power-control and Christie's crime-industry perspectives for total crime, while measures assessing lack of economic means and the economic deprivation were significant for burglary/larceny.  相似文献
