Background: Adolescents and young lesbian, gay and bisexual (LGB) present additional challenges in their development compared to their heterosexual peers which exposes them to high levels of stress and distress that can lead to sexual risk behaviors. Aim: To analyze the sexual behavior, personal characteristics and sexual orientation in adolescents that attended in a center of sexual and reproductive health. Methods: Analytical cross-sectional study conducted in an adolescent population. Data were collected in 2000-2012. Multiple logistic regression was used to quantify comparisons of sexual behaviors and personal variables between LGB and heterosexual adolescents. Results: In total, 5,143 adolescents (median age 16 years, 91.5% women and 97.5% students) were studied, 127 were LGB teenagers. LGB adolescents reported risk having more sexual partners and sexual debut earlier than their heterosexual peers. This risk increased by catholic teenagers. Using contraception methods showed no risk in catholic teenagers but adolescents assigned to another religion or no religion which was a risk factor. Conclusions: The results of this study show that the LGB and heterosexual adolescents are not identical in terms of sexual risk. LGB engages in riskier sexual behaviors than heterosexual counterparts. Healthcare providers and the education sector need to be sensitive to these differences and their implications for health and counseling of adolescents. Source

This paper describes a large obsidian deposit located along the southern banks of Laguna Blanca, on the eastern slope of the Jarellón volcanic caldera near the Chilean-Bolivian border. The obsidian at this site occurs in flows or sheets of deflated black or reddish to brown pebbles, redeposited on the shores of a lake. Blocks of obsidian are only found around the caldera rim. Here we analyze the shape of the obsidian pebbles and their geochemistry, comparing them with previously published data. The results indicate that the geochemical composition of the samples strongly matches previous analyses of obsidian from cultural contexts. This obsidian source was one of the most important sites of obsidian procurement since at least the Formative Period in the Atacama Puna region. © 2010 Wiley Periodicals, Inc. Source

Talca was one of the cities with the greatest housing damage after the F-27 earthquake. Its historical center and 15 surrounding old neighborhoods had most of their housing damaged or destroyed. Two years after the earthquake, most of the destruction remains visible in downtown Talca; however, there is not enough data to illustrate this situation. This paper is focused on analyzing reconstruction policies in view of the current state of reconstruction in the downtown neighborhoods of Talca. Preliminary findings suggest an inadequate reconstruction process, both because a large percentage of urban areas have not yet been intervened and because a considerable number of families are still living in precarious conditions, in emergency housing, in semi-destroyed housing or in self-help built shacks. Likewise, there is a marginal number of solid housing built with subsidy in the downtown area. Lastly, such a reconstruction has been mostly financed by the families themselves, who have decided not to use a State financing system that is regarded as insufficient. Source

Background. Teaching practices of health professionals have been poorly studied from the didactic transposition of disciplinary contents as much in Chile as in Latin America. The logic of the knowledge object and the logic of teaching act converge dialectically at the university classroom. Objective. To describe analytically the representations that health professionals have about their own teaching practices in the disciplinary subjects within the classroom. Materials and methods. A descriptive qualitative design was set up based on the grounded theory, constant comparative method, and the triangulation and convergence principle. The collection techniques of information were: the semi-structured interview, text reading and ethnographic observations. From this analysis ten categories came up: a) Relevance in the teaching knowledge, b) The aim of teaching, c) Appraisal of prior knowledge assessment, d) Usability of didactics, e) Teaching and learning results, f) Disciplinary contents mastery, g) Improvement, h) Teaching style, i) Effectiveness criteria with in the class, j) Slightest knowledge for teaching. To process the verbal data it was used Altlas-ti 6.0 version for the qualitative analysis. Results. The teachers require teaching knowledge to improve the quality of teaching. The concepts of teaching methodology are mainly claimed to the methods and the use of international technology resources. The most use strategy in the teaching process within the classroom is the exhibiting class which is focused on the teacher and close to the behaviorism approach. Conclusion. The dominant pedagogical model is focused on the teacher and it is close to the behaviorism approach, for instance the teaching practices do not represent a systematic teaching task neither is enshrined in the current educative approaches.

Broussonetia papyrifera (L.) Vent. (Magnoliophyta: Urticales), or paper mulberry, is a species of Asian origin dispersed by humans throughout the Pacific. Our aim is to evaluate the genetic variability of this plant in order to determine its potential as a commensal species for studying the mobility and/or migratory movements of the people that carried it. For this study, we analysed the non-coding transcribed spacer sequences (ITS) of ribosomal nuclear DNA found in samples of B. papyrifera collected in Remote Oceania and Taiwan. Our results show three genotypes: the Pacific samples form a distinct and homogenous subgroup, while the Taiwanese accessions present two genotypes. We discuss the relevance of these results in the context of the dispersal of B. papyrifera in the Pacific and its association with Austronesian migration history. © 2011 The Royal Society of New Zealand.
