Psychometric properties of the Brief-COPE for the evaluation of coping strategies in the Chilean population

The Brief-COPE is an abbreviated version of the COPE (Coping Orientation to Problems Experienced) Inventory, a self-report questionnaire developed to assess a broad range of coping responses. Currently, it is one of the best validated and most frequently used measures of coping strategies. The aim of this study was to validate a culturally appropriate Chilean version of the Brief-COPE, assess its psychometric properties and construct and congruent validity. The Spanish version of the Brief-COPE was administrated in a community sample of 1847 Chilean adult (60.4% women) exposed to a variety of stressful experiences. The factorial structure of the inventory was examined by comparing four different models found in previous studies in Latin American population. The results of confirmatory factor analyses revealed, as in the original studies, a 14-factor structure of the Brief-COPE. These dimensions showed adequate internal structure and consistency. The factorial invariance comparing women and men confirmed strict invariance. Additionally, the results showed significant correlation between some Brief-COPE scales, such as denial and substance use, with perceived stress and emotional support and active coping with subjective well-being. Overall, the present work offers a valid and reliable tool for assessing coping strategies in the Chilean population.This study was funded by CONICYT/FONDECYT (grant number 1180134) awarded to Felipe E.

Characterization of secondary deposits of columbite-tantalite minerals found in the city of Rorainópolis (RR), Brazil

Many of the studies about mineral deposits are bringing great information to the scientific community, providing, for example, general characteristics of these deposits, possible source areas and its used in some cases as prospective tools to help in geological mapping. In this way, this study aimed to characterize the alluvial secondary deposits of columbite-tantalite that were found near vicinal 12, about 50km north/northeast of Rorainópolis city, between the BR-174 and BR-210 roads, in the state of Roraima (Brazil), bases on 4 samples that were brought by a resident of the region. To fulfill these objectives, some chemical and mineralogical methods were performed, like: magnetic separation, X-ray diffraction, X-ray fluorescence and petrographic description. The deposits of the region end up being characterized by having a large amount of Fe and Ti (mostly), containing in some places also a large concentration of Niobium and Tantalum. Not all samples have columbite-tantalite, showing that their concentration in some areas of the deposit is quite low. There are samples with less than 1% Nb and Ta and also samples with more than 20% Nb and 6% Ta concentration. These minerals were poorly transported, being identified by the degree of roundness and granulometry of the samples. A weathering cap on some minerals could also be verified. This research work turned out to be relevant, as it provides new data that add to the knowledge of the mineral potential, which has not been fully explored yet

A corpus-based analysis of referentiality in Mapudungun: Preliminary Report

Este artículo expone los lineamientos metodológicos y algunos resultados parciales del estudio de la referencialidad en mapudungun, una lengua aislada hablada en Chile y Argentina con distintos grados de vitalidad. La referencia en el discurso abarca dos operaciones básicas: la individuación de los referentes y su anclaje en el discurso. La presente investigación es parte de un proyecto más amplio que busca identificar los recursos estructurales utilizados por las lenguas en estas operaciones referenciales. Investigamos un conjunto de parámetros estructurales y semánticos de expresiones referenciales tal como ocurren en un corpus de textos en mapudungun pertenecientes a diferentes géneros. Algunos de los hallazgos pueden representar patrones generales de la referencia en textos naturales, otros pueden ser representativos de géneros mapuches específicos. A nivel metodológico, nuestra investigación muestra que es posible fundamentar hipótesis sobre la referencia y la estructura del discurso relacionada con la referencia cuantitativamente, caracterizar los géneros textuales mediante propiedades semánticas y estructurales medibles y descubrir nuevos fenómenos que requieren una explicación.This report presents the methodological guidelines as well as some partial results of the study of referentiality in Mapudungun, a language isolate spoken in Chile and Argentina with different degrees of vitality. Reference in discourse encompasses two basic operations: the individuation of the referents and their anchorage in the discourse. Our research is part of a wider project which seeks to identify the structural resources used by the languages in referential operations. We investigate a set of structural and semantic parameters of referential expressions as they occur in a corpus of Mapudungun texts belonging to different genres. Some of the findings may represent general patterns of reference in natural texts, while others may be representative of specific Mapudungun genres. At a methodological level, our research shows that it is possible to substantiate hypotheses on reference and on discourse structure related to reference by hard figures, to characterize text genres by measurable semantic and structural properties, and to discover new phenomena which demand an explanation.Fil: Golluscio, Lucia Angela.

Artes e infância: estilos musicais de crianças num ambiente “reflexivo”

In this article the concept of “musical style” is introduced as a tool to study the relationship between children and art, and the paradigm of “reflexive interaction” as a “device” to enhance the child’s musical style. The concept of musical style will be introduced as a representation of the child’s identity, a way of expressing her/his self with sounds and music, and to be in communication with others. We will introduce the paradigm of “reflexive interaction”, a particular tool that proved able to support and reinforce the individual musical style of each child, in both child-machine and child-adult interaction. Some scenarios of reflexive interaction both in everyday life and music lessons will be introduced and discussed.Neste artigo, o conceito de “estilo musical” é introduzido como uma ferramenta para estudar a relação entre a criança e a arte, e o paradigma da “interação reflexiva” como um dispositivo para melhorar o estilo musical da criança. O conceito de estilo musical será apresentado como uma representação da identidade da criança, uma maneira de se expressar com sons e música e estar em comunicação com os outros. O paradigma da “interação reflexiva” será introduzido como uma ferramenta particular, que se mostra capaz de apoiar e reforçar o estilo musical individual de cada criança, tanto na interação criança-máquina quanto na interação criança-adulto. Alguns cenários de interação reflexiva, tanto da vida cotidiana quanto da aula de música, também serão apresentados e discutidos.Grupo de Investigación HUM-672 AREA (Análisis de la Realidad EducativA

La enseñanza de la lengua : innovación y reforma

Innovación y reforma. En un discurso acerca de la innovación en la enseñanza de la lengua y de la literatura, no se puede obviar la referencia al nuevo marco curricular establecido en la reforma de la enseñanza. Un cambio curricular implica el propósito de modificar una situación insatisfactoria -en relación con los fines sociales que se asignan a la institución escolar- mediante la revisión de los objetivos, los contenidos y los procedimientos de evaluación. En efecto, el nuevo currículum del área de Lengua y Literatura adopta un enfoque comunicativo y funcional y establece como intenciones educativas el desarrollo de las capacidades de comprensión, de expresión y de reflexión sobre los usos lingüísticos y comunicativos de la sociedad. De acuerdo con estos fines, se fijan unos bloques de contenidos que tienen como eje los saberes de tipo procedimental

Mapping hydrogen storage capacities of UK offshore hydrocarbon fields and exploring potential synergies with offshore wind

Energy storage is an essential component of the transitioning UK energy system, a crucial mechanism for stabilising intermittent renewable electricity supply and meeting seasonal variation in demand. Low-carbon hydrogen provides a balancing mechanism for variable renewable energy supply and demand, and a method for decarbonising domestic heating, essential for meeting the UK's 2050 net-zero targets. Geological hydrogen storage in porous rocks offers large-scale energy storage over a variety of timescales and has promising prospects due to the widespread availability of UK offshore hydrocarbon fields, with established reservoirs and existing infrastructure. This contribution explores the potential for storage within fields in the UK Continental Shelf. Through comparison of available energy storage capacity and current domestic gas demands, we quantify the hydrogen required to decarbonise the UK gas network. We estimate a total hydrogen storage capacity of 3454TWh, significantly exceeding the 120TWh seasonal domestic demand. Multi-criteria decision analysis, in consultation with an expert focus group, identified optimal fields for coupling with offshore wind, which could facilitate large-scale renewable hydrogen production and storage. These results will be used as inputs for future energy system modelling, optimising potential synergies between offshore oil and gas and renewables sectors, in the context of the energy transition.ISSN:0375-6440ISSN:0305-8719ISSN:2041-492

Can brands claim ignorance? Unauthorized subcontracting in apparel supply chains

Unauthorized subcontracting—when suppliers outsource part of their production to a third party without the retailer’s consent—has been common practice in the apparel industry and is often tied to noncompliant working conditions. Because retailers are unaware of the third party, the production process becomes obscure and cannot be tracked. In this paper, we present an empirical study of the factors that can lead suppliers to engage in unauthorized subcontracting. We use data provided by a global supply chain manager with more than 30,000 orders, of which 36% were subcontracted without authorization. We find that the frequency of unauthorized subcontracting across factories has a pronounced bimodal distribution. Moreover, the degree of unauthorized subcontracting in the past is highly related to the probability of engaging in unauthorized subcontracting in the future, which suggests that factories behave as if they choose a strategic level of unauthorized subcontracting. At the order level, we find that state dependence (i.e., the status of an order carrying over to the next one) and price pressure are the key drivers of unauthorized subcontracting. Buyer reputation and lead time also play a role. Finally, we show that unauthorized subcontracting can be predicted correctly for more than 80% of the orders in out-of-sample tests and for about 70% of suppliers. This indicates that retailers can use business analytics to predict unauthorized subcontracting and help prevent it

Review article: studies of fungi in the state of Amazonas, Brazil in the last 10 years

Fungi are eukaryotic beings, uni or multicellular and are present in our daily lives, both in the manufacture of food and in the proliferation of diseases. The occurrence of fungi of the phylum Basidiomycota is most frequently found in the forest, as it is in these places that fungi find the conditions that best guarantee their physiological needs, acting as the main decomposers of organic matter. The present work aims to carry out production analysis on fungi in Amazonas. The review consisted of analyzing scientific articles, dissertations and thesis in the field of mycology in the Amazon region available in the databases PubMed, Scielo, Lilacs, ScienceDirect and Google Scholar, in English and Portuguese. The data collection used the publication period between 2008 and 2018 as the inclusion criterion, the exclusion criterion was the keywords that were not in accordance with the analyzes proposed by the publication criteria. It was found that all related works on fungi are published in scientific journals in the areas of teaching (two), health (five) and the environment (four), with emphasis on the fungi Candida, Aspergillus and Penicillium. The Amazon Forest has been little investigated, mainly in relation to fungi research, which makes it urgent to know about the diversity of fungi, especially in areas of the Brazilian Amazon, where it needs to be measured
