Social welfare as small-scale help: evolutionary psychology and the deservingness heuristic

Public opinion concerning social welfare is largely driven by perceptions of recipient deservingness. Extant research has argued that this heuristic is learned from a variety of cultural, institutional, and ideological sources. The present article provides evidence supporting a different view: that the deservingness heuristic is rooted in psychological categories that evolved over the course of human evolution to regulate small-scale exchanges of help. To test predictions made on the basis of this view, a method designed to measure social categorization is embedded in nationally representative surveys conducted in different countries. Across the national- and individual-level differences that extant research has used to explain the heuristic, people categorize welfare recipients on the basis of whether they are lazy or unlucky. This mode of categorization furthermore induces people to think about large-scale welfare politics as its presumed ancestral equivalent: small-scale help giving. The general implications for research on heuristics are discussed.     

Skin changes following defibrillation. The effect of high voltage direct current

Previously, electrical injuries have been suggested caused only by the concomitant heat developed during the passage of an electrical current. Recent experimental studies on fully anesthetized pigs and the study of one human case have, however, shown typical electrical alterations. The purpose of the present study was further to evaluate the histology of electrically induced changes in the skin in humans. In addition, supplementary in vivo methods for evaluation of skin changes as high-frequency ultrasound and Raman spectroscopy were used. The skin of 11 patients treated with a defibrillation of the heart was examined for macroscopic changes, the skin of eight of them also for histologic changes and for changes observable via supplementary methods. Immediately and 7 days after the defibrillation, fractions of a narrow red ring were observed along the periphery of the tin-foil electrode. Epidermis showed signs previously observed following electrical influence: segmental alterations often related to the openings of sweat ducts, darkstaining or "empty" nuclei and homogeneous cytoplasm, eosinophilic or pale. Dermis did not show the specific sign of electrical influence: deposits of calcium salts on dermal fibres, neither via histologic examination nor via high-frequency ultrasonography and Raman spectroscopy. Fractions of a narrow red ring along the periphery of the electrode showing histological signs of electric influence in epidermis thus appear to be characteristic of high voltage electrical injury.     

Studying the emergence of depression and depressive symptoms during adolescence

The special issue on the emergence and maintenance of depression and depressive symptoms is introduced. The special issue considers two typically separate lines of research, one focusing on severe clinical depression and another on depressive symptoms. The biological, social, and cognitive factors contributing to the emergence of depression in adolescence are highlighted in this special issue.Received Ph.D. from the University of Pennsylvania. Research interests include biological and social development of adolescents and changes in development over a series of life cycle transitions.Received Ph.D. from the University of Chicago. Research interests include biopsychosocial aspects of adoleslcent development.     

The Municipal Bond Market in a Changing Economy

Due primarily to the Tax Reform Act of 1986, the municipal bond market has undergone great changes in the last two years. Because of severe limitations on the purposes for which and processes by which tax-exempt bonds can be issued, the volume of new issues has fallen dramatically. Interest rates, while volatile, have been declining. The municipal market, although dealing with various cross-currents of unrest emanating from credit quality problems, changing buyers, disclosure concerns, and adverse court decisions, nevertheless appears well positioned to concentrate its resources on its traditional role in the financing infrastructure.     

Pubertal timing and grade effects on adjustment

Effects on adjustment of biological maturation and social timing were compared using data from a longitudinal sample of 335 young adolescents, who were followed from the sixth through eighth grades. Biological maturation was estimated from the relative timing of the adolescent growth spurt. Social timing was assessed by grade in school. Five adjustment constructs were examined: school achievement (course grades in five subjects), family relations (a 17-item scale), peer relations (a 10-item scale), body image (an 11-item scale), impulse control (an 8-item scale), and psychopathology (an 11-item emotional tone scale and an 11-item general psychopathology scale). All but one adjustment construct showed grade effects, but only three of the six constructs showed pubertal timing effects. There were no grade by pubertal timing effects. Although there were gender differences for some of the adjustment constructs, there were no gender by pubertal timing effects. The results are discussed in terms of the life-span developmental perspective.Received Ph.D. from the University of Chicago in 1973. Research interest is biopsychosocial development in early adolescence, with a focus on sex differences.Received Ph.D. from the University of Chicago. Research interests are social development, biosocial interactions in early adolescence, and sex differences.     

Estimating the Impact of Education on Political Participation: Evidence from Monozygotic Twins in the United States,Denmark and Sweden

In this study we provide new evidence on the much-discussed effect of education on political participation by utilizing the quasi-experiment of twinning. By looking at the relationship between education and participation within monozygotic (MZ) twin pairs we are able to circumvent traditional sources of confounding of the relationship rooted in genes and early life family environment because MZ twins share both. The results of within-twin pair analyses based on surveys from the United States, Denmark and Sweden show that while the relationship between education and political participation is highly confounded by genes and/or familial environment in all three countries, a positive impact remains of years of education in the US and of high school completion in Denmark. No effect is found in Sweden. Robustness checks suggest that the observed effect is not confounded by within-twin pair differences in prenatal environment nor differential treatment during childhood, and, if anything, that it most likely constitutes a lower bound estimate.     

Facilitators and obstacles to cooperation in international development networks: a network approach

This paper draws attention to the value of a network approach for understanding cooperation in international development networks. The approach emphasises the impact of social interaction, and the values, ideas, and behaviours of individuals on the achievement of development goals. Social network analysis is used to analyse the social structure and dynamics of interaction in an aid-funded development network organisation that aimed to develop optometry capacity in Mozambique. The analysis shows the value of combining quantitative and qualitative methods in a complementary way to identify factors facilitating (network consciousness and social skill) and hindering (power dynamics) cooperation.
