Adolescents Coping with Poverty-Related Family Stress: Prospective Predictors of Coping and Psychological Symptoms

Examined prospective associations among poverty-related family stress, coping, involuntary stress reactivity, and psychological symptoms in a sample of 79 rural, low-income adolescents. Poverty-related family stress predicted adolescents’ anxious/depressed and aggressive behavior 8 months later, controlling for prior symptoms. Coping interacted with initial symptoms and involuntary stress reactivity to predict changes in symptoms over time, showing that primary and secondary control coping were most strongly associated with changes in symptoms for adolescents with low initial symptoms and involuntary stress reactivity. The only significant predictor of coping over time was prior coping, suggesting that coping is not symptom-driven and may be somewhat trait-like. Implications for interventions and additional research are offered. Assistant Professor, University of Denver. Received PhD from University of Vermont.

Variation in state education policies and effects on student performance

There have been few systematic studies of the effects that education policies adopted at the state level have on the quality of schooling within the state. This article, building on a framework developed by Eric Hanushek and Lori Taylor, measures the effects of state policies—in particular, the effects of state teacher certification requirements on SAT performance across states. In an examination of SAT data from 1972 to 1990, the results suggest that students in states with a master's degree requirement for teacher certification had lower SAT scores than students in states without a master's requirement. The empirical model accounts for inputs such as family background and other school factors typically used in education production functions.     

Distinguishing Between Legally and Illegally Produced Gold in South Africa

The identification of gold‐bearing material is essential for combating the theft of gold in South Africa. Material seized in police operations is generally a mixture of gold from different mines, and as such cannot be traced back to a single location. ICP‐OES analysis of material dissolved by acid dissolution provided a database of gold compositions comprising gold from South African mines, illegal gold stolen from the mines, and commercial gold alloys and jewelery. Discrimination between legal and illegal gold was possible due to the presence of Pb, As, Sb, Sn, Se, and Te in the stolen material, elements which are not present in legally produced gold. The presence of these elements is a quick and simple way to distinguish between gold alloys based on refined gold, such as in commercially manufactured jewelery, and gold alloys containing a proportion of unrefined and therefore illegally obtained gold.     

Culture,Sustainability, and Medicine in the Twenty-first Century. Re-grounding the Focus of Medicine Amidst the Current “Global Systemic Shift” and the Forces of the Market: Elements for a Contemporary Social Philosophy of Medicine

This article analyzes the role and the status of medicine within the “post-modern” culture(s) of the West. As we know, culture is a major factor that influences the perception, the interpretation, and the expectations toward medicine, medical institutions, medical politics, and the persons involved with them. When culture changes, the social construct called “medicine” changes. Today, the Western condition of “post-modernity” finds itself in a process of rapid change due to the “global systemic shift” that is manifesting since a couple of years within all four main systemic logics and discoursive patterns of Western societies: in culture, religion, politics, and economics. In this situation, the article tries to elaborate on crucial questions about how a contemporary social philosophy of medicine can be delineated within the current “global systemic shift” and what some consequences and perspectives could be. It pleas for an integrative philosophy of medicine which has to strive to re-integrate the “(de) constructivist” patterns of “nominalistic” post-modern thought (dedicated primarily to freedom and equality) with the “idealistic” patterns of “realistic” neo-humanism (dedicated primarily to the “essence” of human dignity and the possibility of intersubjective morality). Only the institution of a balanced “subjective-objective” paradigm can ensure medicine its appropriate place, role, and status within our rapidly changing society.     

Metabolism and toxicological detection of the designer drug N-(1-phenylcyclohexyl)-3-methoxypropanamine (PCMPA) in rat urine using gas chromatography-mass spectrometry

Studies on the metabolism and the toxicological detection of the phencyclidine-derived designer drug N-(1-phenylcyclohexyl)-3-methoxypropanamine (PCMPA) in rat urine are described using gas chromatographic-mass spectrometric (GC-MS) techniques. Based on the identified metabolites, the following metabolic pathways could be postulated: N-dealkylation, O-demethylation partially followed by oxidation of the resulting alcohol to the corresponding carboxylic acid, hydroxylation of the cyclohexyl ring at different positions, and aromatic hydroxylation. The formed metabolites were identical to those of the homologue N-(1-phenylcyclohexyl)-3-ethoxypropanamine (PCEPA) with exception of the mono hydroxyl metabolites of PCEPA. All PCMPA metabolites were partially excreted in conjugated form. An intake of a common drug users' dose of PCMPA could be detected in rat urine by the authors' systematic toxicological analysis (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction and microwave-assisted acetylation. The STA should be suitable for proof of an intake of PCMPA also in human urine assuming similar metabolism.     

A comparison of hair colour measurement by digital image analysis with reflective spectrophotometry

While reflective spectrophotometry is an established method for measuring macroscopic hair colour, it can be cumbersome to use on a large number of individuals and not all reflective spectrophotometry instruments are easily portable. This study investigates the use of digital photographs to measure hair colour and compares its use to reflective spectrophotometry. An understanding of the accuracy of colour determination by these methods is of relevance when undertaking specific investigations, such as those on the genetics of hair colour. Measurements of hair colour may also be of assistance in cases where a photograph is the only evidence of hair colour available (e.g. surveillance). Using the CIE L^*a^*b^* colour space, the hair colour of 134 individuals of European ancestry was measured by both reflective spectrophotometry and by digital image analysis (in V++). A moderate correlation was found along all three colour axes, with Pearson correlation coefficients of 0.625, 0.593 and 0.513 for L^*, a^* and b^* respectively (p-values = 0.000), with means being significantly overestimated by digital image analysis for all three colour components (by an average of 33.42, 3.38 and 8.00 for L^*, a^* and b^* respectively). When using digital image data to group individuals into clusters previously determined by reflective spectrophotometric analysis using a discriminant analysis, individuals were classified into the correct clusters 85.8% of the time when there were two clusters. The percentage of cases correctly classified decreases as the number of clusters increases. It is concluded that, although more convenient, hair colour measurement from digital images has limited use in situations requiring accurate and consistent measurements.     

Was It Worth It? The Territorial Reform in the Canton of Glarus

This paper examines the financial impact of the 2011 reform of the local governments and jurisdictions in the canton of Glarus. After a popular vote 70 public entities were reorganized to form three large uniformed communes. Previous research showed that amalgamations do not automatically lead to savings in public expenditures and economies of scale. We empirically apply the synthetic control method and show that the territorial reform realized some savings in public expenditure. However, the effect of the reorganization of tasks and responsibilities between the canton and the communes was more influential. The reform must be understood as a horizontal and vertical venture that encompasses both the communes and the canton, much more far‐reaching than a pure local territorial reform.     

Ernesto (Che) Guevara: The Last “Heroic” Guerrilla

We take the opportunity presented by the fiftieth anniversary of the death of Che Guevara to reexamine his life and revolutionary program and the legacy he left behind. Attention is given to the formative influences that led to his introduction to Fidel Castro and his involvement in the Cuban revolution. We take a close look at the stylized theory of revolution that emerged from this experience, his reflective writings on the subject, and his subsequent attempts to generalize and apply his revolutionary model in the Congo and Bolivia. This model is critically interpreted and evaluated through the lense of his eleven month Bolivian campaign. We conclude by examining the ‘paradox’ of Che Guevara. He was a failed guerrilla who remains an iconic symbol of the revolutionary Left. He was an authentic true believer who dreamed that it might be possible to one day forge a utopian society of ‘new men’ and yet, fifty years after his death, his revolutionary project is farther away from being realized than ever. His heroic image, in the meantime, has evolved to become one of the most successful capitalist brands in history.
