Comparative Green Politics: Beyond the European Context?

It is argued that there are significant differences between green electoral politics in Europe and green developments in the affluent non-European west, and that these are such that, despite the greater political formalization of the green movement in Western Europe, there is a sense in which North American and Antipodean developments are ultimately more fundamental than those that have occurred in Europe. Loosely adopting explanatory categories employed by Rudig and Lowe in a Political Studies article, we examine evidence under four sub-heads: electoral thresholds; the historical legacy of the environment movement; the different contextual roles played by the anti-nuclear movement and wilderness experience, and ecology, Marxism and the new left.     

Psychological correlates of teenage motherhood

The social and economic consequences of adolescent motherhood are known, yet the psychological associates are largely unstudied. Clinical studies point to distressing reactions to adolescent pregnancy, and do not reflect changes in social attitudes about teenage parenting. In this study, adolescent mothers (n=62), pregnant teenagers (n=63), and non-pregnant and nonparenting (n=60) adolescents enrolled in public high schools completed measures of socioeconomic status, depression, anxiety, loneliness, self-esteem, and social supports. Findings suggest that adolescent mothers and pregnant teenagers are less distressed by their situation than was once thought. Social supports and socioeconomic status predicted psychological well-being better than parenting status. Expanded school programs for teenage mothers and renewed efforts to enhance young mothers' social and socioeconomic resources are called recommended.Funding was provided by the William T.

The Downstream Benefits of Experimentation

The debate about the cost-effectiveness of randomized fieldexperimentation ignores one of the most important potentialuses of experimental data. This article defines and illustrates"downstream" experimental analysis—that is, analysis ofthe indirect effects of experimental interventions. We arguethat downstream analysis may be as valuable as conventionalanalysis, perhaps even more so in the case of laboratory experimentation.     

Mandibular ramus height as an indicator of human infant age

There were two goals to be achieved from the analysis of 53 skeletonized infants from the Southwest Collection at the National Museum of Natural History. The first objective was to determine whether this infant sample could be aged based on a mandibular measurement. The second was to determine which dimension of the mandible, if any, most accurately predicts infant age within a six-month range. Seven osteometric measurements were applied to each mandible. Statistical analysis determined that the individuals in the Smithsonian's Southwest Collection that were under two-years-old could be accurately aged to within six months. Out of these seven measurements the most accurate age-at-death estimates were generated based on the maximum height of the mandibular ramus. This finding can potentially aid investigators in determining the age-at-death of infants.     

Role of alcohol in heroin overdose

The relationship between ethanol and risk of heroin overdosage was studied. Statistical processing of the results of forensic chemical analysis (460 expert evaluations) carried out in Chelyabinsk Regional Bureau of Forensic Medical Expert Evaluations in 2000 was carried out. The results of morphine and ethanol measurements in the blood and urine from corpses where deaths ensued from narcotic or ethanol poisoning, were analyzed. The concentrations of morphine in the blood and urine were measured on a gaseous chromatographer with mass-selective detector (Hewlett Packard HP 6890/HP-5972). Methods for measuring urinary and blood morphine are described. The results of statistical analysis demonstrated relationships between the age and ethanol concentrations in the blood and urine; blood ethanol and total urinary and blood morphine concentrations; blood concentration of free morphine and presence of 6-monoacetylmorphine in the blood. The authors conclude that the presence of ethanol in the blood together with morphine drastically augments the risk of rapid death from respiration arrest. It can also lead to a relatively high risk of overdosage in experienced narcomaniacs using heroin and ethanol.     

Analysis of ionic ratios in myocardial tissue and their relation to cardiac damage

The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process.
