ESTRUTURA RETÓRICA DE UMA REDAÇÃO DO ENEM
Authors: Cavalcante Filho Luciano , Nogueira Márcia
Published: October 2020

O presente trabalho fundamenta-se na Teoria da Estrutura Retórica do Texto (Rhetorical Structure Theory – RST). De acordo com Mann e Thompson (1988), a RST corresponde a uma ferramenta teórica profícua para a descrição das relações entre as cláusulas de um texto, a análise dos sentidos de conjunções no processo de combinação de orações, o estudo da coerência e a identificação das proposições relacionais que, embora não estejam muitas vezes marcadas, acabam por emergir da estrutura durante o processo de interpretação textual. Com o aparato teórico da RST, analisamos a composição estrutural e as proposições relacionais explícitas e inferidas que emergem em uma redação do ENEM selecionada pelo INEP como exemplo de texto que obteve nota máxima em 2017. Nosso estudo é um exercício de análise textual pautado na RST, com o objetivo de demonstrar como esse aparato teórico pode orientar a análise de uma produção textual de natureza tão específica, explicitando relações entre cláusulas, bem como entre porções textuais maiores, tais como período e parágrafos. Assim, observamos que a redação do ENEM apresentou estrutura retórica condizente com a tipologia textual dissertativo-argumentativa. Foram identificadas relações que estão diretamente envolvidas no desenvolvimento temático e argumentativo, tais como evidência, lista, conclusão e elaboração.
O QUE BRASILEIROS DIZEM ACERCA DE USOS DE CONSTRUÇÕES COM VERBO-SUPORTE?
Authors: Travassos Pâmela Fagundes , Machado Vieira Marcia
Published: October 2020

Focalizamos padrões construcionais com verbo-suporte DAR, enquanto operador de verbalização de elementos não-verbais do tipo (um(a)) X-[a/i]da, (um(a)) X-[a/i]dinha, (um(a)) X-adela e (um(a)) X-(z)inh[o/a], tal como em dar uma escapadinha e dar uma olhadela. Baseamo-nos em pressupostos da Linguística Funcional-Cognitiva e da Gramática de Construções. Utilizamos dados retirados de situações reais de comunicação, do acervo online do jornal O Globo (1925 a 2015), para lidar com o problema da avaliação subjetiva. A metodologia é a de pesquisa experimental baseada em usos observados nesses textos. Os objetivos consistem em observar quais valores são associados por brasileiros a usos dessas construções e descrever características formais e funcionais desses predicadores complexos considerando também a ótica do usuário sobre eles. Resultados apontam que essas construções põem em evidência não só aspectualidade, mas, principalmente, o valor modal, e tais valores são reconhecidos pelos informantes.
ABORDAGEM FUNCIONAL DOS ADVÉRBIOS E ADVERBIAIS DE TEMPO E ASPECTO EM RELATOS
Authors: Santana Jhonathan , Damasceno Gesieny
Published: October 2020

Este artigo objetiva analisar e descrever o comportamento de advérbios e adverbiais de tempo e aspecto, sob a ótica dos processos de divergência (HOPPER, 1991), em reportagens acerca de relatos de violência homofóbica, veiculadas por jornais de circulação online. O tratamento dispensado aos dados foi de natureza holística, seguindo a tendência das pesquisas funcionalistas nas quais a pesquisa se ancora (MARTELOTTA, 2009; 2012; CASTILHO et al., 2014), a fim de que se pudesse efetuar o estudo descritivo desses elementos adverbiais. A investigação revelou, dentre outros aspectos, que a relação semântica mais realizada pelos advérbios/adverbiais de tempo é a de localização temporal definida do evento (80%) e já no que tange aos aspectuais, a relação mais presente foi a de duração do evento (46,8%). Alguns circunstanciadores, em menor proporção, apresentaram um ingrediente de foricidade, atuando na cadeia coesiva do texto.
PRÁTICAS DE ENSINO DE PORTUGUÊS PARA FALANTES DE OUTRAS LÍNGUAS
Authors: Julião da Silva Sérgio
Published: October 2020

A abordagem funcionalista e sua aplicação a práticas didáticas viabilizaram a expansão do ensino de língua para além da gramática prescritiva e a inclusão de diversos aspectos das práticas cotidianas de conversação. O contexto da interação ganha relevância e o ensino de línguas incorpora, assim, elementos que vão além do sintagma ou da frase isolada. O presente trabalho busca demonstrar, através de um estudo de caso com aprendizes de Português para Falantes de Outras Línguas (PFOL) com inglês como língua materna, como um curso baseado exclusivamente na gramática prescritiva apresenta limitações. Para minimizar tais limitações, apresentamos uma proposta de viés funcionalista para o planejamento e a condução de um curso de PFOL. A proposta visa a instrumentalizar os aprendizes com competências não somente linguísticas, mas também sociolinguísticas e pragmáticas.
VARIAÇÃO E MUDANÇA LINGUÍSTICA
Authors: Martins Dall'Orto Lauriê , Durço Ana Paula , Lacerda Patrícia
Published: October 2020

O presente trabalho tem por finalidade discutir a variação e a mudança linguística no âmbito da construcionalização gramatical sincrônica. Para tanto, apresentamos evidências empíricas de dois fenômenos da língua portuguesa – construções com “então” e construções avaliativas com “super”, “mega”, “hiper” e “ultra”. Tomamos como base os postulados da Gramática de Construções nos termos de Goldberg (1995, 2016), de Croft (2001) e de Traugott e Trousdale (2013), no contexto da Linguística Funcional Centrada no Uso. Utilizamos, para as análises qualitativa e quantitativa dos dados, um corpus sincrônico de investigação, composto por textos retirados de blogs, de revistas disponíveis na internet e da mídia social YouTube. Os resultados apontam que, a depender do objeto de análise e dos objetivos do pesquisador, é possível falarmos em mudança e em variação, sob o enfoque do mecanismo da neoanálise e do mecanismo da analogização, mesmo a partir de uma perspectiva sincrônica de análise da construcionalização gramatical.

Authors: SUSANTEZ Çiğdem , CALDEIRA Aldelio
Published: October 2020

In this paper, the thermal comfort of a container with PCM walls has been investigated numerically for a hot summer day in Rio de Janeiro. Four different cases have been investigated. These cases are: (i) container made by Polyurethane plates, which is the reference solution, (ii) RT 22 HC plates, (iii) RT 25 HC plates and (iv) RT 28 HC plates. Analyses have been performed for 10 hours from 08:00 to 18:00 h, and dimensionless numerical results for all investigated cases have been presented. Nondimensional governing equations have been solved by COMSOL Multiphysics finite element modeling and simulation software. Results show that although thermal conductivity of polyurethane is one-eighth of that of PCM, the container with PCM walls present considerably better performance. It has been observed that the average value of the dimensionless temperature inside the container is equal to its initial value at the end of the investigation time for the cases of RT 22 HC and RT 25 HC are used. On the other hand, this value shows increments of 0.1235 (2.35oC) and 0.7710 (14.65oC) respect to initial temperature, respectively for the cases of RT 28 HC and polyurethane are used at the end of that time

Published: October 2020

A cross sectional prospective study was done on 104 patients admitted in the Department of Obstetrics and Gynaecology, Holy Family Red Crescent Medical College Hospital during specific period of one year. The practice of hysterectomy dates back to the middle of 19th century following myomectomy. The indications for hysterectomy were to save life of the patient, relieve sufferings or to correct deformity of organs. Pre-tested structured clinical data sheet was used to obtain necessary data along with records of histopathological reports. The patients who undergone abdominal hysterectomy were mostly between the age 41 to 45 years with Inclusion criteria of Leiomyoma, dysfunctional uterine bleeding. chronic cervicitis, adenomyosis, pelvic inflammatory disease, cervical polyp, post-menopausal bleeding, pelvic endometriosis, choriocarcinoma and ovarian cyst. Most frequent indication was leiomyoma and the chief complain was menorrhagia. Both ovaries had to be removed in most of the patients (72) out of total 104 cases. In some cases one ovary was preserved as per clinical indications. The complications of hysterectomy in present study was found 24% which was much lower than the other studies done earlier as 37% and 35%14. This finding may be due to increased use of prophylactic antibiotic, surgical techniques and improvement of overall aseptic and antiseptic measures taken pre, per and post operative period.

Implementation of Probabilistic Neural Network using Approximate Entr ximate Entropy to Detect Epileptic Seizur o Detect Epileptic Seizures
Authors: Sille Roohi , Sharma Garima , Pradhan N.
Published: October 2020

Epileptic seizures detection is largely based on analysis of Electroencephalogram signals. The ambulatory EEG recordings generate very lengthy data which require a skilled and careful analysis. This tedious procedure necessitates the use of automated systems for epileptic seizure detection. This paper proposes one such automated epileptic seizure detection technique based on Probabilistic Neural Network (PNN) by using a time frequency domain characteristics of EEG signal called Approximate Entropy(ApEn). Our method consists of EEG data collection, feature extraction and classification. EEG data from normal and epileptic subjects was collected, digitized and then fed into the PNN. For feature extraction, the wavelet coefficients are derived using Discrete Wavelet Transformation. For the feature selection stage a new methodology is proposed, which is, comparing the ApEn values of wavelet coefficients of different EEG data. The experimental results portray that this proposed approach efficiently detects the presence of epileptic seizures in EEG signals and showed a reasonable accuracy.

Published: October 2020

A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks [1]. One of the main advantages of the usage of web services is its ability to integrate with the other services through web service composition and realize the required functionality. This paper presents a new paradigm of dynamic web services composition using network analysis paired with backtracking in the perspective of tour planner where booking for flight, car, hotel room, scenic spots, etc are to be done. An algorithm called “Zeittafel” for the selection and scheduling of services that are to be composed is also presented.
A Novel Review on Routing Protocols in MANETs
Authors: Kaur Robinpreet , Rai Mritunjay Kumar
Published: October 2020

Mobile means moving and ad hoc means temporary without any fixed infrastructure so mobile ad hoc networks are a kind of temporary networks in which nodes are moving without any fixed infrastructure or centralized administration. MANETs are generating lots of interest due to their dynamic topology and decentralized administration. Due to the diverse applications which use MANETs for wireless roaming it is a current research issue. There are different aspects which are taken for research like routing, synchronization, power consumption, bandwidth considerations etc. This paper concentrates on routing techniques which is the most challenging issue due to the dynamic topology of ad hoc networks. There are different strategies proposed for efficient routing which claimed to provide improved performance. There are different routing protocols proposed for MANETs which makes it quite difficult to determine which protocol is suitable for different network conditions as proposed by their Quality of service offerings. This paper provides an overview of different routing protocols proposed in literature and also provides a comparison between them.

Formación docente bajo sospecha. Análisis curricular de las Ciencias Sociales en el trayecto formativo de los maestros en la última dictadura cívico-militar en Uruguay (1973 – 1985)
Authors: Bordoli Eloísa , Estala Cecila
Published: October 2020

El presente artículo tiene por objetivo analizar los principales cambios ideológicos y epistémicos que en la última dictadura cívico–militar desarrollada en Uruguay (1973-1985) se operaron a nivel de la formación docente, especialmente en magisterio. El foco empírico se asienta en el análisis de los cambios institucionales y curriculares que se efectuaron a partir de la segunda mitad de los años setenta. Interesa, apreciar el entramado discursivo que sustentó las reformas. Los significantes guerra interna y peligro ante el avance del marxismo internacional se estructuraron en el marco de la llamada Doctrina de la Seguridad Nacional que sirvió de fundamento de las reformas institucionales y curriculares del período. Asumiendo que los currículos se configuran en discursos normativos en el espacio escolar procurando prescribir lo representable y transmisible en cada contexto histórico – social se hará foco en las finalidades formativas, en los contenidos y en la bibliografía de los planes y programas de la formación docente. Se hará énfasis en la asignatura Ciencias Sociales de Formación del núcleo básico común del plan de formación docente en tanto en esta se condensan, los lineamientos propositivos e ideológicos del régimen. La hipótesis que guía el trabajo heurístico se puede formular de la siguiente manera: la lógica estructuradora interna que predominó en el plan y en los programas del núcleo común de 1977 de magisterio se caracterizó por un énfasis ideológico que supuso una minimización epistemológica y un desconocimiento del trabajo acumulado, especialmente, en determinadas disciplinas del área social como el de las Ciencias Sociales.

Authors: Cerqueira Emiliana Barros , Gomes Jaíra Maria Alcobaça
Published: October 2020

Esse estudo analisa o Índice de Vegetação por Diferença Normalizada (NDVI) de municípios do Piauí e Ceará que extraem pó de carnaúba, comparando-o nos anos em que a precipitação pluviométrica foi semelhante e avalia as taxas de crescimento da atividade econômica e da população municipal. Para tanto, usou-se as imagens NDVI/MODIS disponíveis no site da Embrapa, dados sobre pluviometria, do Instituto Nacional de Pesquisas Espaciais e variáveis econômica e demográfica, do Censo Demográfico. As imagens desvelaram supressão de vegetação em algumas localidades decorrentes do aumento da urbanização ou da escala produtiva. Assim, é importante monitorar essas áreas para estabelecer políticas públicas adequadas para a conservação da vegetação nativa, considerando o risco de remoção de carnaúbas.

Authors: Libânio Gilberto , Moro Sueli , Londe Anna Carolina
Published: October 2020

Este artigo examina a relação entre composição das exportações e crescimento econômico, para um amplo conjunto de países, entre 2000 e 2010 – década marcada por forte elevação dos preços de commodities no mercado internacional. Para tanto, propõe um índice de qualidade de exportações, a partir da classificação em categorias de intensidade tecnológica desenvolvida por Lall (2000). Considerando a presença de dependência espacial nas variáveis, estima-se a relação entre qualidade das exportações e crescimento econômico com a utilização de modelos de painel espacial. Os resultados sugerem que – a despeito da grande expansão da demanda e dos preços de commodities durante a maior parte da década – os países com estruturas exportadoras com maior conteúdo tecnológico apresentaram taxas de crescimento mais elevadas durante o período analisado.

Authors: Cancelier Janete Webler , David Cesar De , Facco Janete
Published: October 2020

A agricultura desenvolvida para a produção de alimentos dentro de áreas urbanas/periurbanas vem redefinindo o uso dos espaços, proporcionando transformações nas relações sociais, ambientais e econômicas, modificando as paisagens e as dinâmicas de produção. O crescimento da demanda por alimentos de qualidade tem possibilitado a permanência de atividades agrícolas nos espaços urbanos. O modo de vida pautado na maneira de produzir diferente passa a ser valorizado por desenvolver um sistema de produção particular e de especificidade local. Nesta perspectiva, ocorrem cultivos hortícolas em áreas periurbanas do município de Santa Maria (Rio Grande do Sul). A produção hortícola é considerada uma fonte de entrada de renda para as famílias, pois semanalmente os produtos são comercializados nas feiras, mercados e propriedades.
Processes influencing lower stratospheric water vapour in monsoon
anticyclones: insights from Lagrangian modeling
Authors: Plaza Nuria Pilar , Podglajen Aurélien , Peña-Ortiz Cristina , Ploeger Felix
Published: October 2020

Abstract. We investigate the influence of different chemical and physical processes on the water vapour distribution in the lower stratosphere (LS), in particular in the Asian and North-American monsoon anticyclones (AMA and NAMA, respectively). Specifically, we analyze effects of large-scale temperatures, methane oxidation, ice microphysics, and small-scale atmospheric mixing processes in model experiments with the chemistry transport model CLaMS. All these processes hydrate the LS, in particular over the Asian Monsoon. While ice microphysics has the largest global moistening impact, it is small-scale mixing which dominates the specific signature in the AMA. In particular, the small-scale mixing parameterization strongly contributes to the seasonal and intra-seasonal variability of water vapour in that region and including it in the model simulations results in a significantly improved agreement with observations. Although none of our experiments reproduces the spatial pattern of the NAMA seen in MLS observations, they all exhibit a realistic annual cycle and intra-seasonal variability, which are mainly controlled by temperatures. We further analyse the sensitivity of these results to the domain-filling trajectory set-up used in the five model experiments, here-called Lagrangian Trajectory Filling (LTF). Compared with MLS observations and with a multiyear reference simulation using the standard version of CLaMS, we find that LTF schemes result in a drier global LS and drier water vapour signal over the monsoon regions. Besides, the intra-seasonal variability of water vapour in the AMA is less correlated with MLS during June--August. We relate these results to the fact that the LTF schemes produce a low density of air parcels in the moistest areas of the AMA.

Abstract. In this paper, the continuous on-line measurements of isoprene in the atmosphere have been carried out by using the Differential Optical Absorption Spectroscopy (DOAS) in the band of 202.71–227.72 nm for the first time. Under the zero optical path in the laboratory, different equivalent concentrations of isoprene were measured by the combination of known concentration gas and series calibration cells. The correlation between the measured concentrations and the equivalent concentrations was 0.9996, and the slope was 1.065. The correlation coefficient between DOAS and on-line VOCs instrument is 0.85 and the slope is 0.86 in the comparison of 23 days field observation. It is estimated that the detection limit of isoprene with DOAS is about 0.1 ppb at an optical path of 75 m, and it is verified that isoprene could be measured in the ultraviolet absorption band using DOAS method with high temporal resolution and low maintenance cost.

Abstract. The Tropical Tropopause Layer (14–18.5 km) is the gateway for most air entering the stratosphere, and therefore processes within this layer have an outsized influence in determining global stratospheric ozone and water vapor concentrations. Despite the importance of this layer there are few in situ measurements with the necessary detail to resolve the fine scale processes within this region. Here, we introduce a novel platform for high resolution in situ profiling that lowers and retracts a suspended instrument package beneath drifting long duration balloons in the tropics. During a 100-day circumtropical flight, the instrument collected over 100 two-kilometer profiles of temperature, water vapor and aerosol at one-meter resolution, yielding unprecedented geographic sampling and vertical resolution. The instrument system integrates proven sensors for water vapor, temperature, pressure and cloud and aerosol particles with an innovative mechanical reeling and control system. A technical evaluation of the system performance demonstrated the feasibility of this new measurement platform for future missions with minor modifications. Six instruments planned for two upcoming field campaigns are expected to provide over 4000 profiles through the TTL, quadrupling the number of high-resolution aircraft and balloon profiles collected to date. These and future measurements will provide the necessary resolution to diagnose the importance of competing mechanisms for the transport of water vapor across the TTL.
Overview of the main radiation transport codes

Abstract. Accurate predictions of expected radiation dose levels on
Mars are often provided by specific radiation transport codes that
have been adapted to space conditions. Unsurprisingly, several of the main
space agencies and institutions involved in space research and technology
tend to work with their own in-house radiation codes. We present the
codes that are related to the simulation of the radiation on Mars' surface under different
scenarios. All of these codes have similar fields of application,
but they differ with respect to several aspects, including the energy range and types of
projectiles considered as well as the models of nuclear reactions
considered.
Numerical investigation on the kinetic characteristics of the Yigong
landslide in Tibet, China

Published: October 2020

Abstract. To analyse the kinetic characteristics of a rapid landslide that occurred on 9 April 2000 in Tibet, China, a meshfree numerical method named Smoothed Particle Hydrodynamics (SPH) is introduced, and two-dimensional and three-dimensional models are established in this work. Based on the numerical simulation, the landslide motion process is reproduced and the kinetic characteristics are analysed combined with the field investigation data. In the kinetic analysis, the landslide velocity, run-out distance, landslide accumulation, and energy features are discussed. Simulation results show that the landslide mass undergoes an acceleration stage after failure, then the kinetic energy dissipates gradually due to the friction and collision during the landslide propagation. Finally, the landslide mass blocks the Yigong river and forms a huge landslide dam and an extensive barrier lake. The peak velocity is calculated to be about 100 m/s, and the run-out distance is approximately 8,500 m. The simulation results basically match the data measured in field, thus verifying the good performance of the presented SPH model. This approach can provide a new way to predict hazardous areas and estimate the hazard intensity of rapid landslides.

Abstract. Continental–global scale flood hazard models simulate design floods: theoretical flood events of a given probability. Since they output phenomena unobservable in reality, large-scale models are typically compared to more localised engineering models to evidence their accuracy. However, both types of model may share the same biases and so not validly illustrate predictive skill. Here, we adapt an existing continental-scale design flood framework of the contiguous US to simulate historical flood events. 35 discrete events are modelled and compared to observations of flood extent, water level, and inundated buildings. Model performance was highly variable depending on the flood event chosen and validation data used. While all events were accurately replicated in terms of flood extent, some modelled water levels deviated substantially from those measured in the field. In spite of this, the model generally replicated the observed flood events in the context of terrain data vertical accuracy, extreme discharge measurement uncertainties, and observational field data errors. This analysis highlights the continually improving fidelity of large-scale flood hazard models, yet also evidences the need for considerable advances in the accuracy of routinely collected field and high river flow data in order to interrogate flood inundation models more comprehensively.
Capitalism without Capitalism
Authors: Toscano Alberto
Published: October 2020

This article explores the theorisation of fascism across Žižek’s oeuvre, from the 1980s to the present. It situates his Lacanian response to the problematic category of ‘totalitarianism’ in its original Yugoslav context, foregrounding the critical function of the aesthetic praxis of over-identification, embodied by the Neue Slowenische Kunst and Laibach, in Žižek’s reflections. The article explores the manner in which Žižek provides distinctive answers to the classic topoi of critical theory’s confrontation with fascism: the typology and taxonomy of fascisms; the nature of fascist fantasy; the perverted utopian content and popular impact of fascism. Above all, it investigates the central place that the theorisation of fascism has in Žižek’s reformation of ideology-critique, especially in terms of the lessons it harbours about the functioning of the social law and the unconscious under capitalism.
Agresión y Resentimiento en los Estudiantes Secundarios*
Authors: Leal Francisco , Meneses Mónica , Alarcón Andrés , Karmelic Vesna
Published: October 2020

Se explora la relación entre conductas agresivas en contextos escolares de vulnerabilidad social, y resentimiento, estado de ánimo relativamente permanente que puede surgir con mayor probabilidad en contextos de discriminación, exclusión y marginación social. Se midió el resentimiento con una escala específica y se clasificó la gravedad de las conductas agresivas a partir de las observaciones en el registro escolar individual, en 270 estudiantes de segundo y tercero medio de un liceo de alta vulnerabilidad social. Los alumnos que presentaban conductas agresivas graves mostraron significativamente más resentimiento que el resto de la muestra. Se propone que las conductas agresivas podrían ser comprendidas, al menos parcialmente, como reacción a la violencia social evidente en estos liceos.
Locus de control: Evolución de su concepto y operacionalización
Authors: Oros Laura
Published: October 2020

El estudio del locus de control, un importante recurso de afrontamiento que tienegran relevancia como factor predictivo de otras variables actitudinales, afectivas ycomportamentales, se inició hace ya muchos años. Con el correr del tiempo, se haperfeccionando el entendimiento de este constructo y han ido surgiendo medidascada vez mejores del mismo. Aunque en un comienzo se lo consideraba unidimensional, hoy se han llegado a medir, por lo menos, seis modalidades diferentes que lo integran. Este artículo propone al lector retroceder hasta las primeras conceptualizaciones respecto del locus de control, delineando cronológicamente, y de manera sintética, algunos de los hallazgos que posibilitaron entender el concepto desde una perspectiva multidimensional.
“Conflicto de Rol Familia–Trabajo desde la Perspectiva de los Tipos de Jornada de Trabajo”
Authors: Baez Ximena , Galdames G. Claudia
Published: October 2020

El presente artículo da cuenta de un proceso de investigación sobre el conflicto derol, desde una mirada psicosocial. Su objetivo fue describir y comparar a un grupo de 263 trabajadores hombres de Antofagasta, con jornadas de trabajo ordinaria y trabajadores con jornada excepcional de las mineras que funcionan en la región, respecto del conflicto familia trabajo y de otras dimensiones psicosociales asociadas.Metodológicamente esta investigación empírica utilizó una estrategia cuantitativaque usó la encuesta social y pruebas de comparación estadística de tipoparamétrico. Se puede señalar que el grupo de trabajadores de jornada excepcional tienen un promedio más alto en el conflicto familia trabajo que los trabajadores de jornada ordinaria, y que estos dos grupos se diferencian principalmente sobre otras variables psicosociales tales como implicancia laboral, bienestar psicológico y satisfacción familiar. Desde el punto de vista de la aplicabilidad esta discusión resulta clave para la aceptación explícita del conflicto de rol familia trabajo, particularmente en el grupo de hombres trabajadores de jornadas excepcionales, que está connotando tensiones que incomodan el desempeño en ambos ámbitos. Para el caso de los trabajadores de jornadas ordinarias, si bien han aparecido con menor conflicto se observa la necesidad de abordar políticas de cuidado de la salud general de ellos y sus familias. En este punto surge un debate no resuelto, del cual dependerían las futuras medidas de intervención psicosocial, pues por el momento no queda claro a que instancia le corresponde asumir los aspectos de la salud familiar, y de cómo hacer operar medidas para la compatibilidad de roles, sobretodo cuando se relaciona a las tareas y compromisos familiares de un trabajador.
PLATINUM-BEARING PLACERS: MINERAL ASSOCIATIONS AND THEIR 190Pt-4He AND Re-Os AGES, AND POTENTIAL LINKS WITH LARGE IGNEOUS PROVINCES IN THE SIBERIAN CRATON

Placer deposits in the Siberian platform are closely associated with well-known platiniferous intrusions (Kondyor, Inagli, Noril’sk, Chiney, and Guli) but there are also abundant platinum-group mineral (PGM) placers of large areal extent in the river basins of Siberia (Vilyui, Lena, Aldan, Anabar, and Olenek) for which the primary sources are unknown. The 190Pt-4He dating method is introduced, compared with existing Re-Os isotope dating of PGMs, and applied to Pt-bearing placers of Siberia. Correlations between the 190Pt-4He and Re-Os isotope ages of the PGMs and with ages of major magmatic events in the Siberian craton show that the potential sources for some of the placers are likely buried Precambrian mafic-ultramafic intrusions of Large Igneous Provinces (LIP). The approach of this paper can be applied to other cratonic areas with alluvial PGMs of unknown origin.
Job satisfaction as a correlate of empathic behaviour among health care providers towards their patients
Authors: Iyeke Patrick
Published: October 2020

This study examined the influence of job satisfaction on empathic behaviour of health care workers towards their patients. Four research questions and five hypotheses guided the study. The study is an ex-post facto research design that adopted the correlation method. A sample size of 1,200 health care workers was selected through a multi-stage sampling method. The method of data collection is a questionnaire, whose psychometric properties were adjudged to be adequate. A total of 1,114 copies were questionnaire were returned after administration and was used for data analysis. The analysis was done using Pearson’s correlation and coefficient of determination for the research questions as well as regression and path analysis for the hypotheses at 0.05 alpha level. The result showed that job satisfaction is positively associated with emphatic behaviour of health care workers towards their patients. The study further revealed that the three components of job satisfaction; affective, cognitive and behavioural components were positively associated with emphatic behaviour and that gender does not moderate the influence of the three components of job satisfaction on empathic behaviour of health care workers towards their patients. Based on the findings, recommendations were made.
