The impact of regime type on health: does redistribution explain everything?

Many scholars claim that democracy improves population health. The prevailing explanation for this is that democratic regimes distribute health-promoting resources more widely than autocratic regimes. The central contention of this article is that democracies also have a significant pro-health effect regardless of public redistributive policies. After establishing the theoretical plausibility of the nondistributive effect, a panel of 153 countries for the years 1972 to 2000 is used to examine the relationship between extent of democratic experience and life expectancy. The authors find that democratic governance continues to have a salutary effect on population health even when controls are introduced for the distribution of health-enhancing resources. Data for fifty autocratic countries for the years 1994 to 2007 are then used to examine whether media freedom—independent of government responsiveness—has a positive impact on life expectancy.     

Screening tablets for DOB using surface-enhanced Raman spectroscopy

2,5,-Dimethoxy-4-bromoamphetamine (DOB) is of particular interest among the various "ecstasy" variants because there is an unusually long delay between consumption and effect, which dramatically increases the danger of accidental overdose in users. Screening for DOB in tablets is problematic because it is pharmacologically active at 0.2-3 mg, which is c. 50 times less than 3,4-methylenedioxy-N-methylamphetamine (MDMA) and makes it more difficult to detect in seized tablets using conventional spot tests. The normal Raman spectra of seized DOB tablets are dominated by the bands of the excipient with no evidence of the drug component. Here we report the first use of on-tablet surface-enhanced Raman spectroscopy (SERS) to enhance the signal from a low concentration drug. Raman studies (785-nm excitation) were carried on series of model DOB/lactose tablets (total mass c. 400 mg) containing between 1 mg and 15 microg of DOB and on seized DOB tablets. To generate surface-enhanced spectra, 5 microL of centrifuged silver colloid was dispensed onto the upper surface of the tablets, followed by 5 microL of 1.0 mol/dm(3) NaCl. The probe laser was directed onto the treated area and spectra accumulated for c. 20 sec (10 sec x 2). It was found that the enhancement of the DOB component in the model tablets containing 1 mg DOB/tablet and in the seized tablets tested was so large that their spectra were completely dominated by the vibrational bands of DOB with little or no contribution from the unenhanced lactose excipient. Indeed, the most intense DOB band was visible even in tablets containing just 15 microg of the drug. On-tablet surface-enhanced Raman spectroscopy is a simple method to distinguish between low dose DOB tablets and those with no active constituent. The fact that unique spectra are obtained allows identification of the drug while the lack of sample preparation and short signal accumulation times mean that the entire test can be carried out in <1 min.     

Preliminary investigations into tris(2,2'-bipyridyl) ruthenium III as a chemiluminescent reagent for the detection of 3,6-diacetylmorphine (heroin) on surfaces

The use of tris(2,2'-bipyridyl) ruthenium (III) as a chemiluminescent spray reagent spot-test for heroin is discussed. Two forms of the reagent are investigated an aqueous and an anhydrous where both were found to give vastly different results. The aqueous reagent giving slow, low intensity chemiluminescence whilst the anhydrous reagent gave a fast, bright response in the presence of 3,6-diacetylmorphine. The anhydrous reagent is less sensitive the slow, intensity response is characteristic of only two opiates tested 3,6-diacetylmorphine and 3-monoacetylmorphine.     

Bioterrorism: processing contaminated evidence, the effects of formaldehyde gas on the recovery of latent fingermarks

In the present age of heightened emphasis on counter terrorism, law enforcement and forensic science are constantly evolving and adapting to the motivations and capabilities of terrorist groups and individuals. The use of biological agents on a population, such as anthrax spores, presents unique challenges to the forensic investigator, and the processing of contaminated evidence. In this research, a number of porous and nonporous items were contaminated with viable anthrax spores and marked with latent fingermarks. The test samples were then subjected to a standard formulation of formaldehyde gas. Latent fingermarks were then recovered post decontamination using a range of methods. Standard fumigation, while effective at destroying viable spores, contributed to the degradation of amino acids leading to loss of ridge detail. A new protocol for formaldehyde gas decontamination was developed which allows for the destruction of viable spores and the successful recovery of latent marks, all within a rapid response time of less than 1 h.     

Autosomal microsatellite allele frequencies for 15 regionally defined Aboriginal Australian population datasets

DNA profiling results presented in court must be accompanied by a statistical estimate of its evidential weight. In calculating such statistics, allele frequencies from the tested loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. This paper reports allele frequencies and the results of population genetic testing of autosomal microsatellite profiles from indigenous Australian donors. In contrast to previous practice these data have been collated according to traditional regional boundaries rather than recently imposed State and Territory borders.     

Massively parallel sequencing and the emergence of forensic genomics: Defining the policy and legal issues for law enforcement

Use of DNA in forensic science will be significantly influenced by new technology in coming years. Massively parallel sequencing and forensic genomics will hasten the broadening of forensic DNA analysis beyond short tandem repeats for identity towards a wider array of genetic markers, in applications as diverse as predictive phenotyping, ancestry assignment, and full mitochondrial genome analysis. With these new applications come a range of legal and policy implications, as forensic science touches on areas as diverse as ‘big data’, privacy and protected health information. Although these applications have the potential to make a more immediate and decisive forensic intelligence contribution to criminal investigations, they raise policy issues that will require detailed consideration if this potential is to be realised. The purpose of this paper is to identify the scope of the issues that will confront forensic and user communities.     

The relationship between peer victimization,cognitive appraisals,and adjustment: A systematic review

Underpinned by the transactional model of stress (TMS), this systematic review synthesizes research testing the role of primary and secondary appraisals in the relationship between peer victimization and adjustment. A comprehensive literature search was undertaken and 23 articles were included in the review. Primary appraisals of threat and control, but not blame, mediated the relationship between peer victimization and adjustment. Secondary appraisals of self-efficacy and perceived social support were found to mediate and moderate the relationship. The findings of the review highlight the utility of the TMS in developing our understanding of individual differences in the relationship between peer victimization and adjustment. The development of the TMS in a peer victimization context, and future areas of research are discussed.     

The Response of Chinese Intellectuals to the US War on Terror

Studying the Chinese intellectual response to the US War on Terror, and how the battle between the Chinese liberals and nonliberals fitted into the above debate, the article focuses on two cases, 9-11 and the war in Iraq. Each will be divided into the expressive response (i.e., how the intellectuals reacted physically); the ideological response (i.e., how they interpreted the incidents in ideologically); and the strategic response (i.e., how they proposed the right strategies for the party-state to manage global affairs). After studying the cases, we should discover how the Chinese intellectuals used nationalist rhetoric to disguise their real disagreements, i.e., their views on domestic politics as well as to advance their own national importance.
