A satisfação vital: sua relação com o preconceito, a identidade nacional, a autoestima e o bem-estar material, em imigrantes

El propósito de esta investigación fue estudiar la relación de la satisfacción vital con varios factores psicosociales corrientemente vinculados a los procesos de migración internacional. En concreto, este estudio exploró la relación de la satisfacción vital - componente cognitivo del bienestar subjetivo - con las variables prejuicio grupal percibido, discriminación personal percibida, autoestima global personal, identidad nacional y bienestar material percibido. La investigación, de tipo empírico y cuantitativo, se realizó a través de un muestreo no probabilístico con inmigrantes colombianos en varias ciudades del Ecuador (N = 185). Confirmando las hipótesis, se halló una relación positiva entre la satisfacción vital, el bienestar material percibido y la autoestima. Se confirmó así mismo una relación negativa entre la satisfacción vital, la discriminación personal percibida y la identidad nacional. Estas mismas variables; la autoestima, el bienestar material percibido, la discriminación personal percibida y la identidad nacional, emergieron como predictoras de la satisfacción vital. No se confirmó, en cambio, la relación negativa hipotetizada entre la satisfacción vital y el prejuicio grupal percibido. Se hace un análisis de dichos resultados desde la literatura psicosocial.O propósito desta pesquisa foi estudar a relação da satisfação vital com vários fatores psicossociais correntemente vinculados aos processos de migração internacional.

Specifically, this study explored the relationship between life satisfaction-a cognitivedimension of subjective well-being- and perceived group prejudice, perceived personal discrimination, global personal self-esteem, national identity and perceived material well- being. The research, of empirical quantitative type, was conducted with a non-probabilistic sample of Colombian migrants at several cities of Ecuador. As expected, the hypothesis that life satisfaction was positively related to self -esteem and perceived material well-being was confirmed. Also, a negative correlation was confirmed between life satisfaction, perceived personal discrimination and national identity. Results show that the variables self-esteem, perceived material well-being, perceived personal discrimination and national identity are significant predictors of life satisfaction. Findings didn´t confirm the expected negative association between life satisfaction and perceived group prejudice. Results are analyzed from a psychosocial perspective

A complete 3D numerical study of the effects of pseudoscalar-photon mixing on quasar polarizations

We present the results of three-dimensional simulations of quasar polarizations in the presence of pseudoscalar-photon mixing in the intergalactic medium. The intergalactic magnetic field is assumed to be uncorrelated in wave vector space but correlated in real space. Such a field may be obtained if its origin is primordial. Furthermore we assume that the quasars, located at cosmological distances, have negligible initial polarization. In the presence of pseudoscalar-photon mixing we show, through a direct comparison with observations, that this may explain the observed large scale alignments in quasar polarizations within the framework of big bang cosmology. We find that the simulation results give a reasonably good fit to the observed data.Comment: 15 pages, 8 figures, significant changes, to appear in EPJ

Social Entrepreneurship and Broader Theories: Shedding New Light on the “Bigger Picture”

This article documents the results of a research workshop bringing together six perspectives on social entrepreneurship. The idea was to challenge existing concepts of the economy, the firm, and entrepreneurship in order to shed new light on social entrepreneurship and on our existing theoretical frameworks. The first two contributions use a macro-perspective and discuss the notion of adaptive societies and the tragedies of disharmonization, respectively. Taking a management perspective, the next two focus on the limits of conventional assumptions in management theory, particularly human capital theory and resource-based view. The final two contributions follow an entrepreneurship perspective highlighting the usefulness of mobilization theory and the business model lens to social entrepreneurship. Despite this diversity, all contributions share the fact that they challenge narrow definitions of the unit of analysis in social entrepreneurship; they illustrate the aspect of social embeddedness, and they argue for an open-but-disciplined diversity of theories in social entrepreneurship research

Ralph: A Visible/Infrared Imager for the New Horizons Pluto/Kuiper Belt Mission

The New Horizons instrument named Ralph is a visible/near infrared multi-spectral imager and a short wavelength infrared spectral imager. It is one of the core instruments on New Horizons, NASA's first mission to the Pluto/Charon system and the Kuiper Belt. Ralph combines panchromatic and color imaging capabilities with IR imaging spectroscopy. Its primary purpose is to map the surface geology and composition of these objects, but it will also be used for atmospheric studies and to map the surface temperature. It is a compact, low-mass (10.5 kg), power efficient (7.1 W peak), and robust instrument with good sensitivity and excellent imaging characteristics. Other than a door opened once in flight, it has no moving parts. These characteristics and its high degree of redundancy make Ralph ideally suited to this long-duration flyby reconnaissance mission.Comment: 18 pages, 15 figures, 4 tables; To appear in a special volume of Space Science Reviews on the New Horizons missio

Factors associated with a history of treatment interruption among pregnant women living with HIV in Malawi: A cross-sectional study

Long-term care engagement of women on antiretroviral therapy (ART) is essential to effective HIV public health measures. We sought to explore factors associated with a history of HIV treatment interruption among pregnant women living with HIV presenting to an antenatal clinic in Lilongwe, Malawi. Methods We performed a cross-sectional study of pregnant women living with HIV who had a history of ART interruption presenting for antenatal care. Women were categorized as either retained in HIV treatment or reinitiating care after loss-to-follow up (LTFU). To understand factors associated with treatment interruption, we surveyed socio-demographic and partner relationship characteristics. Crude and adjusted prevalence ratios (aPR) for factors associated with ART interruption were estimated using modified Poisson regression with robust variance. We additionally present patients’ reasons for ART interruption. Results We enrolled 541 pregnant women living with HIV (391 retained and 150 reinitiating). The median age was 30 years (interquartile range (IQR): 25–34). Factors associated with a history of LTFU were age <30 years (aPR 1.46; 95% CI: 1.33–1.63), less than a primary school education (aPR 1.25; CI: 1.08–1.46), initiation of ART during pregnancy or breastfeeding (aPR 1.49, CI: 1.37–1.65), nondisclosure of HIV serostatus to their partner (aPR 1.39, CI: 1.24–1.58), lack of awareness of partner’s HIV status (aPR 1.41, CI: 1.27–1.60), and no contraception use at conception (aPR 1.60, CI 1.40–1.98). Access to care challenges were the most common reasons reported by women for treatment interruption (e.g., relocation, transport costs, or misplacing health documentation). Conclusions Interventions that simplify the ART clinic transfer process, facilitate partner disclosure, and provide counseling about the importance of lifelong ART beyond pregnancy and breastfeeding should be further evaluated for improving retention in ART treatment of women living with HIV in Malawi

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
