Longitudinal neighborhood profiles in delinquency: The decomposition of change

The methods that traditionally have been used to examine changing spatial distributions of crime and delinquency rates are not able to analyze parsimoniously the full range of within-community variation in these rates over time. In this paper, we present a variant of Bryk and Raudenbush's(Psychol. Bull. 101: 147–158, 1987) hierarchical linear model that can simultaneously examine the full range of within- and between-group variation contained in longitudinal data sets. The method is illustrated through an analysis of the delinquency rates characterizing Chicago's neighborhoods between 1930 and 1970.     

HaeⅢ和HinfⅠ酶解DNA指纹图的比较——一例乱伦案的亲子鉴定

<正> DNA指纹技术已经在法医生物物证鉴定中被日益广泛地应用。从理论上说,两种不同的限制性内切酶酶解同一个体DNA产生完全不同的指纹图,虽有这方面的一般性报道,但无进一步的研究。作者用α—珠蛋白-3’HVR探针比较了HinfI和HaeⅢ酶解的DNA指纹图,并将此结果应用于案例鉴定,报道如下。

What is procedural justice: Criteria used by Dutch victims to assess the fairness of criminal justice procedures

The study examines the meaning of procedural justice to Dutch victims of crime. Using victimological research and the group-value or relational model or procedural justice developed by Lind and Tyler, a model for procedural justice judgments is developed and tested using the structural equation model. Data used for the analysis consist of 221 interviews with victims regarding their experience with the public prosecution. Although the emerging model differs from that of Lind and Tyler, results support Lind and Tyler's assertion that procedural justice judgments are normative and not instrumental. Victims are particularly concerned about being treated with dignity and respect and are not interested in influencing the outcome of their case.     

A mechanistic model for the superglue fuming of latent fingerprints

The use of superglue vapors to detect latent fingerprints, known as superglue fuming, is a chemical process that has not been fully described. The role of the fingerprint material in the process, leading to formation of methyl cyanoacrylate polymer at the site of the fingerprint, remains to be established. Films of liquid alkanes respond similarly to actual fingerprints in the fuming experiment. Their responses depended on the hydrocarbon used, viscosity, and film thickness. Aspects such as film thickness appear to be relevant for actual fingerprints as well. A model was proposed in light of these observations. The model compares the process with gas chromatography, in which molecules partition between the gas phase and a stationary phase. Aspects such as accumulation of superglue monomers by partitioning into a thin film (or wax) are consistent with the preferential response of fingerprints on surfaces relative to the background.
