Studying the neurobiology of social interaction with transcranial direct current stimulation--the example of punishing unfairness.

Studying social behavior often requires the simultaneous interaction of many subjects. As yet, however, no painless, noninvasive brain stimulation tool existed that allowed the simultaneous affection of brain processes in many interacting subjects. Here we show that transcranial direct current stimulation (tDCS) can overcome these limits. We apply right prefrontal cathodal tDCS and show that subjects' propensity to punish unfair behavior is reduced significantly.

Associations of perceived body image and subjective social status with levels of physical activity in Mexican American adolescents

The current study is a secondary data analysis of a prospective cohort study that examined demographic and psychosocial variables and their associations with physical activity levels in Mexican-American adolescents in Houston, Texas. Body image, subjective social status, and anxiety were the main variables of interest. The sample included 952 unrelated Mexican-American adolescents in Houston, Texas. The majority (84.2%) of the study population did not meet physical activity standards prescribed by the CDC.^ In a multivariate model controlling for age, socioeconomic status, gender, general body image, preferred body image, subjective social status, and anxiety, gender and subjective social status were found to be the strongest determinants of physical activity levels. Males and those with a high subjective social status were more likely to participate in physical activity than those with low subjective status. Lower levels of anxiety and a more positive body image were also found to be associated with higher levels of physical activity. In multivariate analyses gender and subjective social status showed the strongest associations with physical activity.^

La entrevista como herramienta para una práctica democratizadora de las relaciones sociales : algunas consideraciones teórico-epistemológicas para el trabajo social

Este trabajo intenta realizar un análisis crítico a los contenidos teórico-epistemológicos de la entrevista, en tanto técnica fundamental en Trabajo Social. A través de los aportes de la Filosofía de la Liberación y de la Lógica de los Campos de Bourdieu, se analizan los discursos implícitos en las estrategias comunicacionales, así como las relaciones de poder inmersas en el campo. Se propone el desafío de conjugar con el Otro potencialidades, experiencias, trayectorias y estrategias para la construcción de un proyecto histórico común y emancipador. La entrevista se convierte de esta manera en una herramienta democratizadora de las relaciones sociales.

Effects of inspections in small world social networks with different contagion rules

Inspections are used to prevent tax evasion or any other unlawful behavior. ? The effect of inspections depends on the network topology and the contagion rule. ? The network is modeled as a Watts?Strogatz Small World that is tuned from regular to random. ? Two contagion rules are applied: continuous and discontinuous. ? The equilibrium populations of payers and evaders are obtained in terms of these system parameters.

The relevance of harmonising the technical level of social housing with the urban level of the neighbourhood through the example of the 500 dwellings in Albacete

The Architecture and Household Trade Union built nearly 2,000 subsidized dwellings in Albacete from 1941 to 1971. It was the responsible entity from the end of the Civil War until the beginning of Democracy of the social policy programs in Spain. Later on, and together with the National Housing Institute, were responsible for the construction activity. Its limited budget, scarcity of technical and human resources and an urgent need for new housing developments, constituted the basis for producing a vast housing market of low construction qualities. However, thanks to the true architectonic expertise of some of the professionals, some of the developments were designed with a clear urban strategy and in direct relation with the city, which characterizes them to be studied and conserved. This is the case for the selected development for the analysis, the urban complex of the 500 dwellings in Albacete, the Hermanos Falcó Neighborhood. Designed and built between 1963, Alfonso Crespo and Adolfo Gil architects, and 1977 second reformed project by the architect Fernando Rodríguez. It is characterized by its layout on the territory, its controlled relation with the city and its different types of open blocks. Above all, its spatial and human scale strengths, directly related to the European post-war proposals, have to be emphasized; although its technical deficiencies affect the interior quality of the houses. This paper examines its virtues and failures and proposes, using current tools, its renovation. This proposal main aims are to extend its lifetime and develop the particular and urban sustainability levels.

Unemployment is the scourge, not youth unemployment per se. The misguided policy preoccupation with youth. CEPS Policy Brief No. 294, 26 June 2013

This Policy Brief argues that too much effort and political capital is being spent by the Commission and member states on being seen to be doing something quickly about youth unemployment when, in fact, the structural measures proposed will only have long-term effects. Expectations of immediate relief are running well above what can be delivered, especially at the EU level. Given the macroeconomic situation, no policy option will deliver a significant dent in either youth unemployment or unemployment in general. The EU policies on the table that are supposed to have an immediate effect, such as increased lending from the European Investment Bank to SMEs for the hiring of young people, will only have a very marginal impact on youth unemployment. Moreover, this impact will come mostly to the detriment of older unemployed persons excluded from such a scheme. Given the perceived need to ‘be seen to be doing something’, we fear that policies subsidising young workers de facto at the expense of older workers or, even worse, policies that subsidise older workers for not taking young people’s jobs, will proliferate. In fact, it is not at all clear that young people suffer more from being unemployed than older people, or even disproportionately more than older unemployed individuals. In particular, it is not clear that the much-publicised notion of a ‘lost generation’ with permanent ‘scars’ is relevant only to the young generation. The paper ends by highlighting the much-neglected policy option of encouraging labour mobility within the internal market. Although the Commission is ‘upgrading and modernising’ its tools, much more could be done in this area – to the benefit of the individuals concerned, the member states, and European integration in general.
