A NOTE ON THE EFFECTS OF POPULATION DENSITY AND UNEMPLOYMENT ON URBAN CRIME

This note presents a brief review of reported studies analyzing the effects that population density and unemployment may have on urban crime rates. Very few such empirical studies have been conducted. and their Jindings have been quite contradictory and not entirely conclusive. However, for certain types of crimes, the evidence seems to indicate that the unemployment rate has a positive effect on the crime rate, while the effect of population density, if significant at all, is a negative one.     

Asian transnational organized crime and its impact on the United States: Developing a transnational crime research agenda

Undertaken on behalf of the National Institute of Justice between July 2003 and August 2004, the research goals of this study were to (a) determine high priority areas for research on Asian transnational organized crime (TOC); (b) assess the impact of Asian TOC on the United States; (3) identify relevant data and information sources in Asia; and (4) identify potential collaborative research partners and institutions in Asia. The aim was thus not to examine in detail the organized crime situation in this region, but rather to lay the foundation for a research agenda and strategy that would accomplish that purpose. In seeking to achieve this aim, the researchers used a variety of techniques as part of an overall exploratory methodology. They included four months of interviews (andfield observations) with experts in eight Asian sites, including law enforcement officials, policymakers, and scholars, as well as American officials in each site. Meetings were also held with Asian crime experts in the United States. Interviews and site visits were supplemented with surveys and analyses done by local Asian researchers, an analysis of U.S. indictments, and the review of a large volume of literature. The sites covered by this research are China, Hong Kong, Macau, Taiwan, Japan, Philippines, Thailand, and Cambodia. The major findings are first, that there is little consensus among the Asian authorities on just wliat their main organized crime problems are. Whereas the Asian authorities give higher priority to traditional organized crimes, e.g., gambling, extortion, prostitution, etc., the American authorities focus more on transnational crimes. Consistent with this view, Asian authorities do not see much linkage between the local or regional crime groups about which they are most concerned, and transnational organized crime. Next, contrary to the views and expectations of some American authorities, the commonly expressed view among the respondents in this study is that there is no collaboration or linkage between transnational organized crime groups and terrorists. Finally, the transnational organized crime networks operating in the region are said to be highly specialized, with any overlapping of criminal activities occurring mostly at the level of transportation of goods or people. It is recommended that future collaborative research efforts focus on trafficking in women and children, human smuggling, and drug production and trafficking. These are likely to continue to have the most impact upon the United States and upon U.S. interests in the region. It is further recommended that these research efforts be both bi-lateral (principally with China) and multi-lateral in nature. A wide variety of potentially willing research partners are identified and their strengths and weaknesses are assessed. Finally, a specific strategy for accomplishing the research agenda is proposed. Support for this research was provided by TDL# 1700-215 from the National Institute of Justice.

The expanding galaxy of performing arts: extending theories and questioning practices

This paper introduces the Special Issue on the languages of performing arts and is therefore aimed at designing how the context of the latter can be illuminated by socio-semiotic and multimodal approaches to communication. In this Special Issue, performances and performing arts are described as multimodal semiotic acts that co-deploy a range of semiotic resources to produce and construct meanings across different cultures and ages. Seen as dynamic and interactive processes of meaning-making, their analysis calls for new and multidisciplinary frameworks which are collected in this Special Issue. The introduction gives an overview of these papers and discusses their range of diverse phenomena, both live and recorded, including theatre performances and films, art installations, opera, as well as reading out aloud. By outlining the significance and contribution of different disciplines and fields of studies to the broad area of performance studies, the chapter argues the case for innovative approaches that can extend theories and analyse aesthetic and performative practices in context. With the help of some case studies, it provides guidelines for the reading and interpretation of the several theoretical discussions and practical case studies presented to encourage further multidisciplinary research on these domains.     

Participation in Prison Activities: An Analysis of the Determinants of Participation

The positive associations of participation in prison activities (e.g. socio-cultural activities, educational courses, sports activities, vocational training, etc.), including reduction of recidivism, improvement of wellbeing and contributions to self-worth, are increasingly recognized. However, little is known about the characteristics by which participants differ from non-participants. In response to this research gap, this study aims to examine the determinants of inmate participation in prison activities. The determinants are categorized as outlined by the importation (individual characteristics) and deprivation (prison life characteristics) frameworks. Survey data derived from a research project in a remand prison in Belgium (N?=?486) provided the empirical evidence for the multiple linear regression analyses. The findings indicate that individual deprivation variables are more likely to predict participation. However, our findings also highlight that the combined effects of importation and deprivation characteristics are more powerful in explaining activity participation. The article concludes by discussing some paths for future prison research and implications for theory and practice. It provides impetus to organize and increase participation in prison activities, taking into account the diverse characteristics, needs and competences of the prison population.     

Pulmonary Cement Embolism After Kyphoplasty

Pulmonary polymethylmethacrylate (PMMA) cement embolism after kyphoplasty (KP) surgery is a quite frequent event as well as the pulmonary embolization of central venous catheter fragment. This report shows the case of a subject who, after KP, developed pulmonary embolism and who underwent thoracic surgery. After hospital discharge, the subject advanced a claim for damages toward the hospital where he was operated, complaining sensation of tenderness at the chest surgical scar and esthetic damage. To understand the nature of the embolism (either central venous catheter fragment or cement), chemical investigations were then ordered. Spectrometry identified the PMMA cement used for KP. When doubts rise about the origin of the embolized material, chemical investigations may reveal important data not only for clinical but also for forensic purposes.     

The Application of Voltammetric Analysis of Δ9‐THC for the Reduction of False Positive Results in the Analysis of Suspected Marijuana Plant Matter

The development of methodologies using inexpensive, fast, and reliable instrumention is desirable in illicit drug analysis. The purpose of this study was based on cyclic voltammetry technique to differentiate the electrochemical behavior of ?⁹‐THC, the psychoactive substance in marijuana, and five different extract plants to yield false positive results after analysis protocol for cannabinoids using thin‐layer chromatography and Fast Blue B salt. After applying a deposition potential of ?0.5 V in a glassy carbon working electrode, the results indicated an anodic peak current at 0.0 V versus Ag/AgCl after addition of ?⁹‐THC solution in the electrochemical cell, and limits of detection and quantification were 1.0 ng mL^?1 and 3.5 ng mL^?1, respectively. Other interfering plants showed distinct amperometric responses. This methodology was useful to detect ?⁹‐THC even in the presence of the Fast Blue B salt, which avoided false positive results for all the studied extract plants.     

Forensic Investigation of Formaldehyde in Illicit Products for Hair Treatment by DAD‐HPLC: A Case Study

The illegal use of formalin (commercial formaldehyde) in cosmetic products harms the health of individuals exposed to this substance. Over the last years, the commercial availability of these products, especially those containing irregular dosage of formaldehyde, has increased in Brazil. This work analyzes some products for hair treatment available in the Brazilian market and verifies their safety. The adopted analytical methodology involved sample derivatization with 2,4‐dinitrophenylhydrazine, followed by high‐performance liquid chromatography with ultraviolet detection (UV–VIS) at λ = 365 nm. The limit of quantification is 2.5 × 10^?3% w/w, and the recovery tests were around 93%. Some of the samples contained high and illegal formaldehyde levels ranging from 9% to 19% (w/w) and others presented suitable concentrations of the analyte. On the basis of the results, this work discusses the efficiency and practicality of this analytical method for forensic purposes.
