Adolescent pregnancies in the Amazon Basin of Ecuador: a rights and gender approach to adolescents' sexual and reproductive health

In the Andean region of Latin America over one million adolescent girls get pregnant every year. Adolescent pregnancy (AP) has been associated with adverse health and social outcomes, but it has also been favorably viewed as a pathway to adulthood. AP can also be conceptualized as a marker of inequity, since it disproportionately affects girls from the poorest households and those who have not been able to attend school

Evolution in Australasian Mangrove Forests: Multilocus Phylogenetic Analysis of the Gerygone Warblers (Aves: Acanthizidae)

The mangrove forests of Australasia have many endemic bird species but their evolution and radiation in those habitats has been little studied. One genus with several mangrove specialist species is Gerygone (Passeriformes: Acanthizidae). The phylogeny of the Acanthizidae is reasonably well understood but limited taxon sampling for Gerygone has constrained understanding of its evolution and historical biogeography in mangroves. Here we report on a phylogenetic analysis of Gerygone based on comprehensive taxon sampling and a multilocus dataset of thirteen loci spread across the avian genome (eleven nuclear and two mitochondrial loci). Since Gerygone includes three species restricted to Australia's coastal mangrove forests, we particularly sought to understand the biogeography of their evolution in that ecosystem. Analyses of individual loci, as well as of a concatenated dataset drawn from previous molecular studies indicates that the genus as currently defined is not monophyletic, and that the Grey Gerygone (G. cinerea) from New Guinea should be transferred to the genus Acanthiza. The multilocus approach has permitted the nuanced view of the group's evolution into mangrove ecosystems having occurred on multiple occasions, in three non-overlapping time frames, most likely first by the G. magnirostris lineage, and subsequently followed by those of G. tenebrosa and G. levigaster

Capital social en áreas rurales: adaptación al español y validación factorial de una escala

El capital social se considera un determinante estructural de desarrollo y bienestar social. Su componente cognitivo evalúa el grado de confianza de la población en sus sistemas de organización social, así como las interacciones comunitarias que estructuran respuestas sociales a los problemas sociales. Existen pocas escalas disponibles para la medición de este constructo. Este trabajo presenta los resultados de la adaptación al español y validación psicométrica de una escala para la medición de capital social en contextos rurales. Se adaptó al español la escala de capital social cognitivo de Wang. Se aplicaron 1200 cuestionarios a adultos en 12 veredas de Tierralta (Colombia) seleccionados con muestreo aleatorio simple estratificado. Se realizó análisis factorial de la escala a partir de una matriz de correlación policórica. El análisis factorial exploratorio sugiere la existencia de dos factores principales distribuidos así: 7 ítems para el factor 1 (confianza) (valor propio 3.23.) y 2 ítems para el factor 2 (desconfianza) (valor propio 1.40). Como fue observado por Wang, Q9 y Q10 parecen preguntas ambiguas que no aportan suficiente a ninguno de los factores. Se presenta la primera validación factorial al español de la escala de capital social de Wang en el contexto social de la Colombia rural

A multi-site collaborative study of the hostile priming effect

Data Accessibility Statement: See Table 1.Supplementary data: Peer Review History - docx file - available online at: https://online.ucpress.edu/collabra/article/7/1/18738/116070/A-Multi-Site-Collaborative-Study-of-the-Hostile#supplementary-data .In a now-classic study by Srull and Wyer (1979), people who were exposed to phrases with hostile content subsequently judged a man as being more hostile. And this “hostile priming effect” has had a significant influence on the field of social cognition over the subsequent decades. However, a recent multi-lab collaborative study (McCarthy et al., 2018) that closely followed the methods described by Srull and Wyer (1979) found a hostile priming effect that was nearly zero, which casts doubt on whether these methods reliably produce an effect. To address some limitations with McCarthy et al. (2018), the current multi-site collaborative study included data collected from 29 labs. Each lab conducted a close replication (total N = 2,123) and a conceptual replication (total N = 2,579) of Srull and Wyer’s methods. The hostile priming effect for both the close replication (d = 0.09, 95% CI [-0.04, 0.22], z = 1.34, p = .16) and the conceptual replication (d = 0.05, 95% CI [-0.04, 0.15], z = 1.15, p = .58) were not significantly different from zero and, if the true effects are non-zero, were smaller than what most labs could feasibly and routinely detect. Despite our best efforts to produce favorable conditions for the effect to emerge, we did not detect a hostile priming effect. We suggest that researchers should not invest more resources into trying to detect a hostile priming effect using methods like those described in Srull and Wyer (1979).We have no funding to declare for this project

Condiciones para el acceso universal a la salud en América Latina: derechos sociales, protección social y restricciones financieras y políticas Conditions for universal access to health in Latin America: social rights, social protection and financial and political constraints

Tras una sucinta problematización de la equidad en salud, sus determinantes sociales y sectoriales, se analizan aspectos macroeconómicos del comportamiento reciente del gasto en salud en la región. Dadas las importantes tensiones contemporáneas respecto de los derechos y la definición de prestaciones de salud, se tratan tres experiencias emblemáticas, de sistemas de salud muy diversos: Chile, Colombia y México. Ellas abarcan distintos aspectos: la garantía de las prestaciones, la reducción de formas de racionamiento implícitas y/o de barreras de entrada, o bien aspectos de calidad.<br>After a brief review of the concept of health equity and its social and sectoral determinants, some macroeconomic aspects of health expenditure in Latin America are considered. Given the significant contemporary tensions with regard to social rights and the definition of health benefits, three emblematic experiences are analyzed in very different health systems, namely those of Chile, Colombia and Mexico. They cover different aspects, such as the guarantee of health benefits, the reduction of forms of implicit rationing and/or barriers to admission, and also aspects related to the quality of services
