Acute arsenic poisoning: clinical, toxicological, histopathological, and forensic features

This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.     

Semen analysis using methods of molecular genetics--a case report

The presented case report describes the exclusion of the suspect of a sexual offence by means of methods of molecular genetics. Pretests for prostate-specific antigen performed at the beginning of the investigation and cytological sperm tests were negative. Nevertheless, by combining the methods of differential lysis and DNA quantification a small number of spermatozoa could be demonstrated in the trace evidence. Subsequently, the profile of the woman's boyfriend, with whom she had had unprotected vaginal intercourse two days before the incident, could be detected in the fraction of the hard lysis.     

Variability in Citizens’ Reactions to Different Types of Negative Campaigns

Do negative advertisements lower voters’ evaluations of the targeted candidate? We theorize that there is much to be gained by examining the variance in the content and tone of negative campaign messages and the variance in voters’ sensitivity to negative political rhetoric. We employ data from the 2006 Cooperative Congressional Election Study to investigate the impact of negative campaigning in U.S. Senate campaigns. We sampled 1,045 respondents in 21 of the 28 U.S. Senate races featuring a majority party incumbent and challenger. In addition to the survey data, we collected contextual data regarding the political advertisements aired during the campaigns and the news coverage of these campaigns in state newspapers. The evidence suggests that the impact of negative information is multifaceted, and under some circumstances, substantial. We find that uncivil and relevant negative messages are the most powerful, especially for people with less tolerance for negative political rhetoric.     

The Gapology of the Obama Vote in the 2008 Democratic Presidential Primaries

In their competition for the 2008 Democratic nomination, Barack Obama and Hillary Clinton developed distinct demographic bases of support. This study will analyze the demographic divides in the 2008 Democratic presidential primaries, focusing on the “gaps” that emerged in the support of Obama. Obama’s demographic bases of support were African-Americans, younger voters, educated voted, those with no religion affiliation, wealthier voters, males, political independents, and ideological liberals. Despite the considerable amount of attention given to the gender gap, a number of demographic gaps were more significant. Race was by far the most important gap and a key component of Obama’s victory was his tremendous support from African-American voters.     

Labor union membership and voting across nations

Despite a large literature on voter turnout around the world, our understanding of the role of labor union membership remains muddled. In this paper, we examine the relationship between union membership and voting. Using individual level International Social Science Program (ISSP) data from thirty-two countries, we find that union members are more likely to vote and that the substantive effect rivals that of other common predictors of voting. This relationship is also largely invariant across an array of demographic factors, indicating that unions tend to be “equal opportunity mobilizers.” We also find that unions have “spillover” effects: controlling for a variety of other factors, even non-union members are more likely to turn out to vote in countries with higher union densities. In sum, we find that labor unions have a consistent political influence across a wide set of countries.     

Contracting for Indigenous Health Care: Towards Mutual Accountability

In Australia and other industrialised countries, governments contract with the non‐government sector for the provision of primary health care to indigenous peoples. Australian governments have developed policies and funding programs to support this health sector, but the current arrangements are unduly complex and fragmented. The results of our study show that the complex contractual environment for Aboriginal Community‐Controlled Health Services (ACCHSs) and their funders is an unintended but inevitable result of a quasi‐classical approach to contracts applied by multiple funders. The analysis in this article highlights potential policy and program changes that could improve the effectiveness of funding and accountability arrangements, based on the use of an alliance contracting model, better performance indicators and greater clarity in the relative roles of national and jurisdictional governments.     

Estimation of stature from static and dynamic footprints

The ability to estimate accurately from known parameters is a fundamental aspect of science and is evident as an emerging approach in the area of footprints and stature estimation within the field of forensic identification. There are numerous foot dimensions that have been measured in the literature to predict stature with varying degrees of confidence but few studies have tried to link the strength of estimation to anatomical landmarks. Such an approach is utilised in this study which estimates stature from the right footprints of sixty one adult male and female UK participants. Static and dynamic footprints were taken from each volunteer using the 'inkless paper system'. The prints were digitised and twelve length, width and angle measurements were chosen for the analysis. The highest correlations with stature were shown to be the heel to fourth toe print for the static group of footprints (r=0.786, p<0.01), and the heel to fifth toe print in the dynamic footprints (r=0.858, p<0.01). Collinearity statistics suggest the heel to fifth toe print length measurement is independent and not influenced by any other variables in the estimation of stature for the dynamic prints. Linear regression equations for this measurement presented the smallest standard error of estimate (SEE) and highest shared variance (R(2)) of all included variables (SEE 4.16, R(2) 0.74). Our study discusses a potential anatomical explanation as to why the lateral border of the foot and hence the impression it makes upon a hard surface, is a more stable indicator in the estimation of stature. The investigation recommends the use of Calc_A4 and Calc_A5 length measurements when estimating stature from footprint impressions.     

Analysis with the Combur-Test--special aspects in forensic trace examination

The Combur Test is a ready-made and easy-to-use pretest for blood. It is based on the oxidation of tetramethylbenzidine (TMB), which is catalysed by haemoglobin and its derivatives. Despite its high sensitivity, there are many known substances which are responsible for false positive and false negative test results. On the basis of experiments of our own, case reports and the pertinent literature special aspects of the application of the Combur Test in the forensic routine case work are discussed.
