Mining contexts involving Indigenous peoples have become complex terrains for ethnographic research, marked by a high degree of politicisation, conflict, and a dense landscape of social actors. As spaces of both encounter and dissonance, or misencounter, between asymmetrical actors, these settings demand a critically situated reflection on the positionality of the researcher, the purposes of the research, and the forms of engagement adopted in the field. This article is situated within the socio-environmental conflict surrounding the Pascua Lama binational mining project (2000- 2021), alongside the simultaneous process of political and legal recognition of the Diaguita of Huasco Alto as an Indigenous people (Atacama Region, north of Chile). Drawing on long-term ethnographic research, this text reflects on the methodological, ethical, and epistemological challenges of fieldwork in Indigen...

This article denotes a socially relevant problem that is related to the absence of women and their history in the official curricular constructions of Chile and Peru. The method followed is related to the postulates of Critical Literacy, adapting leading questions for the construction of categories of analysis and documentary research. Among the main conclusions, it can be stated that both curricula, from comparative perspectives, do not propose or offer sufficient spaces for the inclusion of women and their history. In addition, the curriculum construction is framed in traditional perspectives that reveal the protagonism of white men with political, economic and / or military power, where women, when they are referred, are carried out from subordinate positions and linked to the domestic and private. We can argue that although women are visible in some areas of the curriculum, such pres...

El presente artículo denota un problema socialmente relevante que tiene relación con la ausencia de las mujeres y su historia en las construcciones curriculares oficiales de Chile y Perú. El método seguido se relaciona con los postulados de la Literacidad Crítica, adaptando preguntas conductoras para la construcción de categorías de análisis y pesquisa documental. Entre las principales conclusiones se puede afirmar que ambos currículos, desde perspectivas comparadas, no plantean ni ofrecen espacios suficientes para la inclusión de las mujeres y su historia. Además, la construcción curricular se enmarca en perspectivas tradicionales que relevan el protagonismo de los hombres blancos con poder político, económico y/o bélico, donde las mujeres cuando son referidas, es realizado desde posiciones subordinadas y ligadas a planos domésticos y privados. Podemos plantear que, aunq...

En el presente trabajo, se problematiza la forma en la que se articulan ejercicios de memoria urbana, posicionando a la literatura dentro de las disputas de la memoria, desde donde se puede visibilizar el pasado no resuelto y reaccionar ante los relatos hegemónicos que se pretendieron instalar en después de la dictadura cívico militar (1973-1990). Para ello, se analiza la obra El palacio de la Risa, texto publicado en 1994 en el que Germán Marín reconstruye la historia de Villa Grimaldi, espacio utilizado por el régimen de Pinochet como un centro de detención, tortura y exterminio bajo el nombre de Cuartel Terranova. Desde las ruinas de un espacio baldío en el presente postdictatorial, va develándose una memoria traumática que la transición política quería olvidar. Al análisis se suma bibliografía teórica y crítica sobre el mismo tema, con el objetivo de reflexionar ace...

La cerámica pintada/engobada es uno de los elementos más emblemáticos del Complejo El Vergel del Sur de Chile (1000-1550 d.C.). Si bien se ha abordado su variabilidad desde aspectos tipológicos, decorativos y tecnológicos, faltaba integrar más información respecto a las distintas elecciones en su manufactura para observar la distribución de los modos de hacer. Con aquello como objetivo, se procedió a analizar las pinturas y engobes de material cerámico fragmentado pintado/engobado de cinco sitios domésticos de diferentes áreas geográficas. Estas se analizaron mediante LA-ICP-MS, dando cuenta de las distintas «recetas» utilizadas en su confección. Sobre la base de lo anterior, se identificaron distintos grupos composicionales en engobes y pinturas que se comparten en ciertos ejes geográficos y que pueden responder a una circulación de conocimientos, materias primas y/o v...

El trabajo de tesis desarrollado, tuvo por objetivo obtener los principales parámetros radioeléctricos de un sistema de comunicación móvil, que permita la ampliación de la red móvil 4G LTE del operador Bitel en las Asociaciones San Antonio y La Unión del sector de Viñani. Para lograr ello, se tuvo que analizar la cobertura de la red móvil existente del operador BITEL en el ámbito de estudio mediante la determinación de los indicadores de desempeño (KPI) utilizando la metodología denominada Drive Test. El resultado de las 1564 mediciones efectuadas, permitió determinar que en la zona de estudio no existió una buena cobertura de la red móvil 4G LTE existente, lo cual llevó a realizar un estudio radioeléctrico para proponer una solución tecnológica de una nueva Estación Base LTE. La propuesta de una estación base en la zona de estudio se desarrolló en dos etapas; la p...

El impacto del duelo en la vida cotidiana de las personas es relevante, sobre todo en población de estudiantes universitarios. Para la medición de este constructo se presenta la escala del Inventario del Duelo Complicado, la que tiene escasos estudios de validación en el contexto peruano. Ante esta situación, la presente investigación presenta como objetivo analizar las propiedades psicométricas del Inventario del Duelo Complicado, la cual se constituye de tres dimensiones correlacionadas de Recuerdos del difunto, Sensación de vacío y Presencia-vivencia. Para esto, se utilizó una muestra de 350 jóvenes universitarios seleccionados mediante un muestreo por conveniencia, cuya edad promedio fue de 20.3 años (DE= 2.4) y el 67.1%estuvo constituido por mujeres. Los resultados de la estructura interna fueron determinados por medio del análisis factorial confirmatorio (AFC) obtenién...

Objectives: To determine cost-effectiveness in homologous intrauterine insemination (IUI) outcomes in women 38 years or older in a human reproduction unit and compare results with those of women of similar age treated with complex assisted reproduction technology as published by the Latin American Assisted Reproductive Registry (RedLara) 2009. Design: Retrospective, comparative study. Setting: Unidad de Reproduccion Humana, Pontificia Universidad Catolica de Chile, Santiago, Chile. Participants: Women treated with homologous intrauterine insemination. Interventions: Review of results obtained in 5 421 homologous intrauterine insemina tion cycles (IUI) performed between January 2000 and September 2011. In order to analyze the impact of advanced maternal age, we compared rates obtained in women younger than 38 years old (4 000 cycles) with those of women 38 years and older (1 421 cycles). ...

In recent decades, the reflection on the teaching practices has been considered as an important means among the teacher trainers. Nevertheless, chilean research note that the universities of this country have not achieved that students of Teaching Programs may develop reflections on their pedagogical procedures systematically. This situation is no far from the reality of students of Pedagogía Media en Ciencias Naturales y Biología from Universidad Católica de Temuco. They achieve only in some cases, and intuitively, reflections that may help them improve their performance. The purpose of this research is to strengthen the levels of students’ reflection. In this context, the investigation is a qualitative one with a unique case study design. It points to the relevance of the use of class filming as a strategy which favors reflective processes on the pedagogical practice in collegiate...

En las últimas décadas, la reflexión respecto de las prácticas profesionales docentes ha sido considerada como un medio de desarrollo importante entre los formadores de profesores. Sin embargo, investigaciones chilenas dan cuenta que las universidades de este país no han logrado que los estudiantes de pedagogía desarrollen sistemáticamente reflexiones en relación a su quehacer docente. Esta situación no se aleja de la realidad que viven los estudiantes de la carrera de Pedagogía Media en Ciencias Naturales y Biología de la Universidad Católica de Temuco. Estos logran solo en algunos casos, y de forma intuitiva, reflexiones para la mejora de su mejorar desempeño. El propósito de esta investigación es fortalecer los niveles de reflexión de estudiantes de pedagogía. En este contexto, la investigación es cualitativa con diseño de estudio de caso único y evidenció la rele...

This paper analyses concessive resources with a mitigating function which are found in argumentative acts in the PRESEEA corpus from Santiago, Chile. Based on data from 36 semi-structured interviews, the behaviour of concessive-oppositional moves and concessive discourse particles in argumentative acts is analyzed, and their sociolinguistic variation is described in relation to the speakers’ gender, age and level of education. The key findings highlight that in Chilean Spanish there are at least 12 strategies that fulfill a mitigating concessive function, among which “sí, pero (yes, but) + negation”, “aunque (even though)”, “no, pero (no, but) + assertion” and “a pesar (de) que (despite the fact that)” stand out. These strategies are linked to the functions of self-protection and face prevention in the development of the argumentative act. Furthermore, it is also obser...
