APEC labour markets: Structural change and the Asian financial crisis

This study examines the impacts of longer-term structural changes on the labour markets of Asia Pacific Economic Cooperation (APEC) member economies, as well as the short-run labour market consequences of the Asian financial crisis. All APEC economies have experienced significant structural change in the process of development. A major factor in this structural change has been increased trade intensity (increase in exports and imports as a share of GDP) that has occurred over the last 20 years. Because these structural changes have been extensively induced by trade liberalisation, this study provides insights into the likely consequences of the implementation of APEC's agenda on trade and investment liberalisation and facilitation. The impact of structural change is examined using a range of data, such as disaggregated changes in output and employment by industry and occupation over the period 1980 to 1997, and data on changes in trade intensity for each of the APEC nations. Other data, such as changes in rates of urbanization, are also used to indicate the other important concomitant effects of economic transformation. For several Asian economies, the linear path of growth and structural change was severely disrupted by the Asian financial crisis. This article examines the impact of this crisis on Asian labour markets, in general, and those most affected by the crisis, in particular. In many countries within the region, a failure of education and training systems to respond to often rapid shifts in the skill composition of labour demand is leading to industry and occupation specific labour shortages. International labour migration within the APEC region is viewed as a product of these structural changes and a mechanism that assists in filling gaps in the labour markets of the region's economies.     

Development of a Protein‐based Human Identification Capability from a Single Hair

Shed human hair (lacking root nuclear DNA) frequently contributes important information to forensic investigations involving human identification. Detection of genetic variation observed in amino acid sequences of hair proteins provides a new suite of identity markers that augment microscopic hair analysis and mitochondrial DNA sequencing. In this study, a new method that completely dissolves single hairs using a combination of heat, ultrasonication, and surfactants was developed. Dissolved proteins were digested and genetically variant peptide (GVP) profiles were obtained for single hairs (25 mm) via high‐resolution nanoflow liquid chromatography‐based mass spectrometry and a novel exome‐driven bioinformatic approach. Overall, 6519 unique peptides were identified and a total of 57 GVPs were confirmed. Random match probabilities ranged between 2.6 × 10^?2 and 6.0 × 10^?9. The new bioinformatic strategy and ability to analyze GVPs in forensically relevant samples sizes demonstrate applicability of this approach to distinguish individuals in forensic contexts.     

Optimal storage conditions for highly dilute DNA samples: a role for trehalose as a preserving agent

DNA extraction from trace samples or noninvasively collected samples often results in the recovery of low concentration solutions of DNA that are prone to DNA degradation or other loss. Because of the difficulty in obtaining such samples, and their potentially high value in wildlife and forensic studies, it is critical that optimal methods are employed for their long-term storage. We assessed the amplification yield of samples kept under different storage conditions with the addition of potential preserving agents. We stored dilutions of known concentration human placental DNA, and gorilla fecal DNA, under four conditions (+4 degrees C, -20 degrees C, -80 degrees C, dry at room temperature), and with three additives (Tris EDTA (TE) buffer, Hind III digested Lambda DNA, trehalose). The effectiveness of the treatment methods was tested at regular intervals using qPCR to assess the quantity of amplifiable DNA, and a PCR assay of a larger 757 bp fragment to evaluate the quality of that remaining DNA. The highest quantity of DNA remained in samples stored at -80 degrees C, regardless of storage additives, and those dried at room temperature in the presence of trehalose. Surprisingly, DNA quality was best preserved in the presence of trehalose, either dried or at -80 degrees C; significant quality loss occurred with -20 degrees C and +4 degrees C storage.     

Predictions of Future Dangerousness in Capital Murder Trials: Is It Time to “Disinvent the Wheel?”

Although recent U.S. Supreme Court decisions regarding the death penalty (e.g., Atkins v. Virginia, 2002) have renewed interest in mental health issues, one topic that has not received much attention recently is the ongoing use of expert testimony to support claims that defendants represent a continuing threat to society. In this article, we (a) review prior research relevant to determining the accuracy of clinical predictions that capital defendants will commit future acts of criminal violence; (b) summarize new data from current and former death row inmates in Texas that bolster the claim that such predictions are gross overestimates of risk; and (c) review extant research addressing the potential utility of various risk assessment instruments that increasingly are being used to reinforce clinical predictions in capital trials. Despite significant recent advances in the field of risk assessment, clinical assertions that a defendant is likely to commit future violent acts appear to be highly inaccurate and ethically questionable at best. Moreover, available research offers little support for the claim that the accuracy of these predictions will be appreciably improved by relying on more structured risk assessment measures that have some demonstrated predictive validity in other contexts.Portions of this article were written while the first author was a member of the Department of Psychology at Sam Houston State University.
