Scenes from a mall: Retail training and the social exclusion of low-skilled workers

In this article we examine how post-industrial Britain and Denmark undertake vocational training for low-skilled retail workers. Specifically, we evaluate whether leaders in training skilled industrial workers are also doing the best job with low-skilled service workers. While Danish retail is increasingly becoming a haven for low-skilled workers, British workers are gaining in skills levels with the transition to services even in the retail sector. While some suggest that social democratic countries have sacrificed the political interests of low-skilled workers in order to protect core manufacturing workers, we find no evidence of this. Rather, the high expectations of vocational training in Denmark have forged barriers to the easy admission of low-skilled service workers, while the British system provides more entry points for vocational training at different levels. The structures of coordination that had narrowed the gap between white-collar and blue-collar manufacturing workers during the industrial age are creating new cleavages in the post-industrial economy.     

Use of subpopulation data in Australian forensic DNA casework

DNA profiling evidence presented in court should be accompanied by a reliable estimate of its evidential weight. In calculating such statistics, allele frequencies from commonly employed autosomal microsatellite loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. Typically this occurs at broadly defined bio-geographic categories, such as Caucasian or Asian. Datasets are commonly administered at the jurisdictional level. This paper focuses on Australian jurisdictions and assesses whether this current practice is appropriate for Aboriginal Australian and Caucasian populations alike. In keeping with other studies we observe negligible differences between Caucasian populations within Australia when segregated geographically. However segregation of Aboriginal Australian population data along contemporary State and Territory lines appears to mask the diversity that exists within this subpopulation. For this reason datasets collated along more traditional lines may be more appropriate, particularly to distinguish the most genetically differentiated populations residing in the north of the continent.     

Sensitive and specific quantification of human genomic deoxyribonucleic acid (DNA) in forensic science specimens: casework examples.

We describe the forensic science application of a method for quantification of human genomic deoxyribonucleic acid (DNA). The two cases cited in this report involve DNA samples extracted from skin tissue and bloodstained clothing recovered from different crime scenes. High-molecular-weight DNA was recovered from both specimens, and the concentrations of these DNAs were estimated to be approximately 0.5 microgram/microL by ethidium bromide/agarose gel electrophoresis. Using the human-specific DNA probe p17H8 (locus D17Z1) to quantify the amount of human genomic DNA in these samples, it is shown that less than 1% of the DNA isolated from the skin tissue is of human origin and that the DNA isolated from the bloodstained clothing is effectively devoid of human DNA sequences. These case examples illustrate the need to quantify not only the total amount of DNA recovered from forensic casework material, but also the proportion of the DNA that is of human origin.     

Applications of isoelectric focusing in forensic serology

The typing of certain polymorphic proteins present in human body fluids is an important aspect of the analysis of serological evidence. This is particularly true when dealing with evidence related to violent criminal activity such as homocide, assault, or rape. Until recently, the routine analysis of the genetic polymorphisms of interest relied upon conventional electrophoretic techniques such as horizontal starch or agarose slab gel or both, cellulose acetate, and vertical polyacrylamide gradient gel methods. These techniques adequately separate a limited number of common variants. In some cases, these methods are still those of choice. However, as a result of the nature of the conventional approach, problems with time required for analysis, resolution, diffusion of bands, sensitivity of protein detection, and cost are often encountered. Isoelectric focusing (IEF) offers an effective alternative to conventional electrophoresis for genetic marker typing. This method exploits the isoelectric point of allelic products rather than charge-to-mass ratio in a particular pH environment. The advantages of employing IEF include: reduction of time of analysis, increased resolution of protein bands, the possibility of subtyping existing phenotypes, increased sensitivity of detection, the counteraction of diffusion effects, and reduced cost per sample.     

A survey of the incidence of missing anterior teeth: potential value in bite mark analysis.

Bite mark analysis involves comparison of individual dental characteristics between a dentition and the bite injury. A bite mark injury may result from sexual assault, or physical assault, and defensive injuries, and as such can be used to link a suspect to a victim or vice versa. Missing teeth are one of the characteristics that could implicate or exclude a suspected biter. However frequency data for use by forensic odontologists can only be collated from epidemiological studies. Therefore an audit was undertaken of missing anterior teeth in adult patients (n = 1010) attending for treatment, gathering data that could be more relevant to odontology. One in five of the sample presented with missing teeth that were either replaced with a denture (11%), not replaced (6%) or missing with the gap closed (2%).     

Sexual asphyxia in siblings

We present an accidental autoerotic asphyxiation of a 24-year-old man. Further investigation revealed that 18 years earlier, his brother, then 13, had been found dead, hanging in the family bathroom. Although that death had been ruled a suicide, reevaluation of the death scene indicates that this was also an autoerotic asphyxiation. This is the first reported case of sexual asphyxia involving siblings.     

Latinos/as in the criminal and juvenile justice systems

With few exceptions, prior explanations of racially disparate punishment have followed a dichotomous approach (i.e., African American versus Caucasian), due in part to the limitations of existing data. Researchers have either excluded Latino/a, defendants or treated them as a monolithic group. Consequently, there is not much on Latinos/as, whose experiences with the criminal and juvenile justice systems differ from those of African American and Caucasian. This article expands on current literature by providing a thorough overview of existing literature on Latino/as. It critiques this body of literature and lists ten common methodological flaws that may contribute to findings of equal treatment. Finally, it provides a concise summary of the main subgroups within the umbrella term ‘Latino/a’ to highlight the heterogeneity within this classification.
