The cost price of expertise as an objective index of the work-share coefficient of the forensic medical expert]

The author suggests a method for estimating the net cost of a forensic medical expert investigation, consisting in calculation of an objective real coefficient of the ratio of various expert investigations to the reference value. The ratio between forensic medical investigation budget and the total number of these investigations forms the basis for the estimation of the net cost of an expert evaluation.     

Report of a European collaborative exercise comparing DNA typing results using a single locus VNTR probe

A collaborative exercise was carried out in 1989 among 12 European forensic laboratories using the single locus VNTR probe pYNH24, the restriction enzyme HinfI, the same set of human genomic DNA samples, and a standardized DNA size marker. The objectives of the exercise were: (1) to study the degree of variation within and between laboratories, (2) to obtain information on requirements for technical standardization allowing the exchange of typing results and (3) to compare different approaches for the identification of allelic DNA fragments of unknown size. Each laboratory carried out up to 10 independent typing experiments using the same DNA samples. The results were analysed independently by two laboratories using three different methods. The results of the exercise demonstrate the correlation of typing that can be achieved within and between laboratories under conditions of minimal standardization.     

Media influence on attitudes toward guns and gun control

This study employs the 1995 National Opinion Survey of Crime and Justice to examine the effect that media consumption (hours of television viewing per week, regular viewing of crime drama, and primary source of crime news) has on attitudes towards guns and gun control. Logistic regression results indicate that regular viewers of crime shows are more likely to oppose gun control and believe that firearms prevent crime. Respondents who receive their primary crime news from the print media are more likely to disagree with making it easier to conceal firearms. The author suggests that violent depiction of crime on television may influence viewers’ attitudes toward guns and gun control.     

The polymerase chain reaction and post-mortem forensic identity testing: application of amplified D1S80 and HLA-DQ alpha loci to the identification of fire victims.

The application of DNA typing methods after amplification by the polymerase chain reaction (PCR) of DNA derived from body tissues from charred fire victims was investigated. A total of 26 different tissue specimens from ten extensively burned individuals were analyzed. The samples included femoral muscle, psoas muscle, bone marrow and blood. The post-mortem period varied from 38 to 183 h. After amplifying the DNA by PCR from the various tissues, the D1S80 locus was analyzed with a high resolution polyacrylamide gel electrophoresis technique followed by silver staining and the alleles of the HLA-DQ alpha locus were detected by using a reverse dot blot format. All samples could be typed for both loci and the genotypes were consistent in the various tissues from each individual. A parentage test was performed in two cases and Mendelian inheritance of the alleles for both loci was observed.     

The Economics of Prisons

This survey scans the English language research on prisons published since the appearance of Becker's (1968) seminal piece. After first describing the economic nature of prison and parole, issues concerning comparative institutional analysis and organizational design are discussed, including the role of private prisons. Empirical evidence on production functions for prisons, recidivism and offender rehabilitation programs is reviewed. A brief overview of policy issues and suggestions for future research concludes the survey.     

The characteristics of injuries to the thoracic spine in children with a forward flexion

Excessive flexure of the thoracic spine in childhood may result in latent lesions of the middle thoracic vertebra and intervertebral disks visible by X-ray and on sagittal cuts. The prior deformation may be judged by their morphological signs. Ability of infantile vertebral bodies to recover their form after load removal reduces reliability of mathematical processing of X-ray data. Use of X-ray method for examination of thoracic spine in expert practical work makes it possible to detect lesions and mechanism of their formation.     

Cultural and institutional determinants of economic growth: A cross-section analysis

Economic growth rates for the period 1968–1987 are analyzed for ninety countries. Culture, political and economic arrangements, and personal freedoms are statistically significant determinants of growth. Personal freedom is shown to be a normal good whose demand might be affected by cultural influences. Democracies raise personal freedoms,ceteris paribus, and, consequently, grow more quickly than non-democratic regimes. Evidence is found for the convergence hypothesis; other things equal, lower income countries grow more rapidly than higher income countries.
