A gaze to rural education according to scientific discourses during the last decade

He largest proportion of illiteracy and lack of access to education in the world is concentrated in rural areas; therefore it is important to ensure there is access to quality education in these spots. This challenge is assumed by different branches of social research and it is reflected within the publication of articles in scientific journals. In the present document the scientific discourse surrounding the theme of rural education during the last decade was analyzed. To do this, the paper focuses on three aspects: the countries that set the agenda, the geographical areas that represent most of the attention and the prevalent themes within continents. It was observed that USA was the most productive country in terms of scientific writings with 30%; that Asia is really interested in health issues associated to rural education; that in Europe gender issues are on the table and that the African and Asian continents, as well as Latin America, are interested only on their own issues, as 100% of the times they only wrote about themselves.

COMUNICAÇÃO INSTITUCIONAL E UNIVERSIDADE: diretrizes para a divulgação científica no estado de Mato Grosso

O estudo visa identificar as iniciativas de Divulgação Científica empreendidas pela Universidade Federal de Mato Grosso (UFMT) e Universidade do Estado de Mato Grosso (Unemat), com vistas à atualização e ao aperfeiçoamento da comunicação institucional, maior interação com interlocutores e fortalecimento da imagem do estado como produtor de CT&I. Foram empreendidas pesquisas bibliográficas e documentais, áreas prioritárias de fomento e difusão científica; entrevistas; auditoria de imagem na mídia estadual; diagnóstico dos principais produtos de jornalismo científico desenvolvidos pela UFMT e Unemat, assim como iniciativas conjuntas (revista Fapemat Ciência e Rede de Divulgação Científica). O método investigativo adotado pode ser caracterizado como Pesquisa Participante, concebido em estreita associação com resolução de problemas, tomada de consciência ou produção de novos conhecimentos (THIOLLENT, 1996, 1997). Tal estratégia agrega distintas técnicas de pesquisa social, definidas em função de cada fase do processo de investigação. A partir da análise dos conteúdos científicos publicados nos jornais estaduais, foi possível verificar que essas IES públicas ainda não ocupam lugar relevante em tais veículos, o que pode ser justificado pela inadequação de linguagem ou canais de relacionamento, assim como, pela necessidade de uma política de divulgação mais eficiente. O mapeamento dos portais e canais de mídias sociais institucionais evidenciou que a utilização desses veículos ainda pode ser mais bem dinamizada. Por fim, as conclusões apontam que diferenças culturais e institucionais entre as duas IES inviabilizam a adoção de uma Política de Comunicação Científica integrada, comum entre UFMT e Unemat. O que pode ser considerado, é o desenvolvimento de ações para a dinamização de divulgação dessas instituições, no âmbito do Sistema Estadual de CT&I.

Cladistic association analysis of Y chromosome effects on alcohol dependence and related personality traits

Association between Y chromosome haplotype variation and alcohol dependence and related personality traits was investigated in a large sample of psychiatrically diagnosed Finnish males. Haplotypes were constructed for 359 individuals using alleles at eight loci (seven microsatellite loci and a nucleotide substitution in the DYZ3 alphoid satellite locus). A cladogram linking the 102 observed haplotype configurations was constructed by using parsimony with a single-step mutation model. Then, a series of contingency tables nested according to the cladogram hierarchy were used to test for association between Y haplotype and alcohol dependence. Finally, using only alcohol-dependent subjects, we tested for association between Y haplotype and personality variables postulated to define subtypes of alcoholism—antisocial personality disorder, novelty seeking, harm avoidance, and reward dependence. Significant association with alcohol dependence was observed at three Y haplotype clades, with significance levels of P = 0.002, P = 0.020, and P = 0.010. Within alcohol-dependent subjects, no relationship was revealed between Y haplotype and antisocial personality disorder, novelty seeking, harm avoidance, or reward dependence. These results demonstrate, by using a fully objective association design, that differences among Y chromosomes contribute to variation in vulnerability to alcohol dependence. However, they do not demonstrate an association between Y haplotype and the personality variables thought to underlie the subtypes of alcoholism.

Moving from medical to health systems classifications of deaths : extending verbal autopsy to collect information on the circumstances of mortality

Funding A Health Systems Research Initiative Development Grant from the UK Department for International Development (DFID), Economic and Social Research Council (ESRC), Medical Research Council (MRC (and the Wellcome Trust (MR/N005597/1) funds the research presented in this paper. Support for the Agincourt HDSS including verbal autopsies was provided by The Wellcome Trust, UK (grants 058893/Z/99/A; 069683/Z/02/Z; 085477/Z/08/Z; 085477/B/08/Z), and the University of the Witwatersrand and Medical Research Council, South Africa.

Using rare mutations to estimate population divergence times: A maximum likelihood approach

In this paper we propose a method to estimate by maximum likelihood the divergence time between two populations, specifically designed for the analysis of nonrecurrent rare mutations. Given the rapidly growing amount of data, rare disease mutations affecting humans seem the most suitable candidates for this method. The estimator RD, and its conditional version RDc, were derived, assuming that the population dynamics of rare alleles can be described by using a birth–death process approximation and that each mutation arose before the split of a common ancestral population into the two diverging populations. The RD estimator seems more suitable for large sample sizes and few alleles, whose age can be approximated, whereas the RDc estimator appears preferable when this is not the case. When applied to three cystic fibrosis mutations, the estimator RD could not exclude a very recent time of divergence among three Mediterranean populations. On the other hand, the divergence time between these populations and the Danish population was estimated to be, on the average, 4,500 or 15,000 years, assuming or not a selective advantage for cystic fibrosis carriers, respectively. Confidence intervals are large, however, and can probably be reduced only by analyzing more alleles or loci.

The asymptotic distribution of canonical correlations and vectors in higher-order cointegrated models

The study of the large-sample distribution of the canonical correlations and variates in cointegrated models is extended from the first-order autoregression model to autoregression of any (finite) order. The cointegrated process considered here is nonstationary in some dimensions and stationary in some other directions, but the first difference (the “error-correction form”) is stationary. The asymptotic distribution of the canonical correlations between the first differences and the predictor variables as well as the corresponding canonical variables is obtained under the assumption that the process is Gaussian. The method of analysis is similar to that used for the first-order process.

Re-Examining the Stop-Signal Task to Test Competing Theories of AD/HD

The current study tested two competing models of Attention-Deficit/Hyperactivity Disorder (AD/HD), the inhibition and state regulation theories, by conducting fine-grained analyses of the Stop-Signal Task and another putative measure of behavioral inhibition, the Gordon Continuous Performance Test (G-CPT), in a large sample of children and adolescents. The inhibition theory posits that performance on these tasks reflects increased difficulties for AD/HD participants to inhibit prepotent responses. The model predicts that putative stop-signal reaction time (SSRT) group differences on the Stop-Signal Task will be primarily related to AD/HD participants requiring more warning than control participants to inhibit to the stop-signal and emphasizes the relative importance of commission errors, particularly "impulsive" type commissions, over other error types on the G-CPT. The state regulation theory, on the other hand, proposes response variability due to difficulties maintaining an optimal state of arousal as the primary deficit in AD/HD. This model predicts that SSRT differences will be more attributable to slower and/or more variable reaction time (RT) in the AD/HD group, as opposed to reflecting inhibitory deficits. State regulation assumptions also emphasize the relative importance of omission errors and "slow processing" type commissions over other error types on the G-CPT. Overall, results of Stop-Signal Task analyses were more supportive of state regulation predictions and showed that greater response variability (i.e., SDRT) in the AD/HD group was not reducible to slow mean reaction time (MRT) and that response variability made a larger contribution to increased SSRT in the AD/HD group than inhibitory processes. Examined further, ex-Gaussian analyses of Stop-Signal Task go-trial RT distributions revealed that increased variability in the AD/HD group was not due solely to a few excessively long RTs in the tail of the AD/HD distribution (i.e., tau), but rather indicated the importance of response variability throughout AD/HD group performance on the Stop-Signal Task, as well as the notable sensitivity of ex-Gaussian analyses to variability in data screening procedures. Results of G-CPT analyses indicated some support for the inhibition model, although error type analyses failed to further differentiate the theories. Finally, inclusion of primary variables of interest in exploratory factor analysis with other neurocognitive predictors of AD/HD indicated response variability as a separable construct and further supported its role in Stop-Signal Task performance. Response variability did not, however, make a unique contribution to the prediction of AD/HD symptoms beyond measures of motor processing speed in multiple deficit regression analyses. Results have implications for the interpretation of the processes reflected in widely-used variables in the AD/HD literature, as well as for the theoretical understanding of AD/HD.

Leading With the Relationship: The Role of the Therapeutic Relationship in Motivational Interviewing

Motivational Interviewing (MI) is a brief evidence-based treatment that is most commonly used to treat addictive behaviors and to encourage diet and lifestyle changes and treatment adherence in health care settings. In recent years MI's use has been expanded to multiple other client populations in clinical psychology, as well as to other sectors, such as in education, and international non-profit work (Hettema at al., 2005). MI was inspired by research that demonstrated a high correlation between therapist application of the client-centered skill of accurate empathy and a reduction in drinking behaviors (Miller et al., 1980). MI contains both relational and technical components that are intended to operate synergistically. Despite a large body of research on MI treatment outcomes, variation in effectiveness has been found among studies, and the active ingredients of MI, particularly the relational aspects, are not well understood. As a result, the use of MI in many treatment settings is limited to the technical components of MI without a theory-based integration of the therapeutic relationship. This paper focuses on the contribution of the relational component to the effectiveness of MI, and explores the synergistic relationship between the technical and relational components of MI. A literature review of MI and the trans-theoretical literature on the therapeutic relationship is followed by two case illustrations. The paper concludes with recommendations for the field.

Estudo de alterações estruturais cerebrais em pacientes com esquizofrenia crônica e de primeiro episódio através de imagens por ressonância magnética com morfometria baseada no voxel

Introdução: Embora alterações estruturais cerebrais na esquizofrenia venham sendo repetidamente demonstradas em estudos de ressonância magnética (RM), ainda permanece incerto se tais alterações são estáticas ou progressivas. Enquanto estudos longitudinais são tradicionalmente utilizados na avaliação da questão da progressão, estudos transversais de neuroimagem comparando diretamente pacientes com esquizofrenia crônica e de primeiro episódio a controles saudáveis têm sido bastante raros até o presente. Com o recente interesse em meganálises combinando dados multicêntricos de RM visando-se a maior poder estatístico, o presente estudo multicêntrico de morfometria baseada no voxel (VBM) foi realizado para avaliar os padrões de alterações estruturais cerebrais segundo os diferentes estágios da doença, bem como para avaliar quais (se alguma) dessas alterações se correlacionariam especificamente a moderadores clínicos potenciais, tais como exposição cumulativa a antipsicóticos, tempo de doença e gravidade da doença. Métodos: Selecionou-se uma ampla amostra de pacientes com esquizofrenia (161, sendo 99 crônicos e 62 de primeiro episódio) e controles (151) a partir de quatro estudos prévios de RM (1,5T) realizados na mesma região do Brasil. O processamento e análise das imagens foi realizado usando-se o software Statistical Parametric Mapping (SPM8) com emprego do algoritmo DARTEL (diffeomorphic anatomical registration through exponentiated Lie algebra). Os efeitos de grupo sobre os volumes regionais de substância cinzenta (SC) foram analisados através de comparações voxel-a-voxel por análises de covariância em modelos lineares gerais, inserindo-se, em todas as análises, o volume total de SC, protocolo do scanner, idade e sexo como variáveis de confusão. Por fim, foram realizadas análises de correlação entre os aludidos moderadores clínicos potenciais e os volumes cerebrais globais e regionais. Resultados: Os pacientes com esquizofrenia de primeiro episódio apresentaram reduções volumétricas sutis em comparação aos controles, em um circuito neural circunscrito e identificável apenas em análises SVC (small volume correction) [p < 0.05, com correção family-wise error (FWE)], incluindo a ínsula, estruturas têmporo-límbicas e corpo estriado. Os pacientes crônicos, por outro lado, apresentaram um padrão de alterações extensas comparativamente aos controles, envolvendo os córtices frontais orbitais, superiores e inferiores bilateralmente, córtex frontal médio direito, ambos os córtices cingulados anteriores, ambas as ínsulas, e os córtices temporais superior e médio direitos (p < 0.05, análises whole-brain com correção FWE). Foram encontradas correlações negativas significantes entre exposição cumulativa a antipsicóticos e volumes globais de SC e substância branca nos pacientes com esquizofrenia, embora as correlações com reduções regionais não tenham sido significantes. Detectaram-se, ainda, correlações negativas significantes entre tempo de doença e volumes regionais relativos da ínsula esquerda, córtex cingulado anterior direito e córtices pré-frontais dorsolaterais nas análises SVC para os grupos conjuntos (esquizofrenia crônica e de primeiro episódio). Conclusão: Os achados supracitados indicam que: a) as alterações estruturais associadas com o diagnóstico de esquizofrenia são mais disseminadas na forma crônica em comparação à de primeiro episódio; b) reduções volumétricas regionais em áreas específicas do cérebro podem variar em função do tempo de doença; c) a exposição cumulativa a antipsicóticos associou-se a alterações volumétricas globais, e não regionais

[C II] and 12^CO(1-0) emission maps in HLSJ091828.6+514223: a strongly lensed interacting system AT z = 5.24

We present Submillimeter Array [C II] 158 μm and Karl G. Jansky Very Large Array 12^CO(1-0) line emission maps for the bright, lensed, submillimeter source at z = 5.2430 behind A 773: HLSJ091828.6+514223 (HLS0918). We combine these measurements with previously reported line profiles, including multiple 12^CO rotational transitions, [C I], water, and [N II], providing some of the best constraints on the properties of the interstellar medium in a galaxy at z > 5. HLS0918 has a total far-infrared (FIR) luminosity L_FIR(8–1000 μm) = (1.6 ± 0.1) × 10^14 L_☉ μ^–1, where the total magnification μ_total = 8.9 ± 1.9, via a new lens model from the [C II] and continuum maps. Despite a HyLIRG luminosity, the FIR continuum shape resembles that of a local LIRG. We simultaneously fit all of the observed spectral line profiles, finding four components that correspond cleanly to discrete spatial structures identified in the maps. The two most redshifted spectral components occupy the nucleus of a massive galaxy, with a source-plane separation <1 kpc. The reddest dominates the continuum map (demagnified L_FIR, component = (1.1 ± 0.2) × 10^13 L_☉) and excites strong water emission in both nuclear components via a powerful FIR radiation field from the intense star formation. A third star-forming component is most likely a region of a merging companion (ΔV ~ 500 km s^–1) exhibiting generally similar gas properties. The bluest component originates from a spatially distinct region and photodissociation region analysis suggests that it is lower density, cooler, and forming stars less vigorously than the other components. Strikingly, it has very strong [N II] emission, which may suggest an ionized, molecular outflow. This comprehensive view of gas properties and morphology in HLS0918 previews the science possible for a large sample of high-redshift galaxies once ALMA attains full sensitivity.

Qualidade nutricional de rações para cães: Influência de Zn na absorção de Cu e na prevenção de doença hepática

As rações comerciais devem ser um alimento balanceado que supra todas as exigências nutricionais nas diferentes fases da vida do animal. Sua formulação deve conter ingredientes de qualidade, em proporções adequadas. É de fundamental importância o conhecimento do valor nutricional das rações, para assegurar que o cão esteja ingerindo diariamente quantidades corretas dos nutrientes. O desbalanço de elementos essenciais e a presença de elementos tóxicos podem causar desequilíbrios nutricionais, doenças e, até mesmo, consequências fatais aos cães. O cobre é um dos vários elementos de importância a ser estudado quanto aos defeitos metabólicos nos cães. O acúmulo de cobre no fígado pode ocasionar lesões progressivas nas organelas dos hepatócitos, resultando em hepatite crônica e cirrose. Diante disso, este trabalho teve como objetivos (I) quantificação dos elementos químicos com função nutricional e com potencial tóxico presentes nas rações para cães adultos e filhotes, (II) avaliação da composição centesimal das rações amostradas, (III) avaliação da variação dos elementos químicos entre as amostras de ração de um mesmo lote de produção (IV), estudo da representatividade de pequenas porções-teste, (V) avaliação da bioacessibilidade de cobre em rações, com experimento in vitro. Os elementos químicos Al, As, Br, Ca, Cl, Co, Cr, Cs, Cu, Fe, I, K, La, Mg, Mn, Na, P, Rb, Sb, Sc, Se, Ti, U e Zn foram determinados pela análise por ativação neutrônica instrumental (INAA). A composição centesimal foi avaliada de acordo com os métodos recomendados da AOAC. A homogeneidade de distribuição dos elementos químicos nas rações foi avaliada pela análise de amostras grandes (LS-NAA). A bioacessibilidade de cobre nas rações foi estimada por meio da simulação da digestão gastrointestinal in vitro. Foi possível determinar por INAA todos os nutrientes minerais, isto é, Ca, P, K, Na, Cl, Mg, Fe, Cu, Mn, Zn, I e Se, com limites estabelecidos pela Association of American Feed Control Officials. Foram notadas em algumas rações altas concentrações de Al, Sb e U, elementos com grande potencial tóxico. Cerca de 16 % das amostras de ração apresentaram, pelo menos, um parâmetro não conforme quanto à composição centesimal. Os resultados obtidos por LS-NAA e NAA convencional mostraram variação na composição entre os sacos de ração para Br, Ca, Na e Zn, com boa concordância entre ambos os métodos. O emprego da LS-NAA combinada com NAA convencional permitiu observar que pequenas porções-teste (350 mg) de ração são representativas comparadas com aquelas de 1 kg para Br, Ca, K, Na e Zn. Em todas as rações para cães, 50 % do cobre presente estava sob a forma bioacessível

Productividad científica en España sobre las profesiones de comunicación entre 1971 y 2009

A la luz de la Convergencia Europea, los títulos de grado en comunicación elaborados en España están fundamentados en las competencias requeridas para el ejercicio de cada una de las profesiones. Es necesario, pues, analizar al profesional de la Publicidad y las Relaciones Públicas, del Periodismo y de la Comunicación Audiovisual. Este trabajo pretende conocer los estudios de investigación centrados en este tema. Realiza una revisión sistemática de los artículos, libros y tesis doctorales sobre las profesiones de comunicador desde la década de los setenta hasta 2009, en las bases de datos ISOC, ISBN y TESEO. Extrae indicadores bibliométricos y sigue los criterios de evaluación mantenidos por la CNEAI (Comisión Nacional Evaluadora de la Actividad Investigadora) y la ANECA (Agencia Nacional de Evaluación de la Calidad y Acreditación) para valorar las investigaciones. Los resultados muestran que es la firma del Plan Bolonia lo que parece iniciar un ciclo de atención hacia las profesiones de comunicación. Periodismo es la profesión más estudiada. La mayoría de los estudios no cumplen con los criterios de calidad de las agencias evaluadoras. En conjunto, se observa la necesidad de aumentar la cantidad y la calidad de las investigaciones para realizar planes de estudios «basados en evidencia», así como la pertinencia de fortalecer la formación de los investigadores en la metodología de la investigación social.

How do primary health care teams learn to integrate intimate partner violence (IPV) management? A realist evaluation protocol

Background: Despite the existence of ample literature dealing, on the one hand, with the integration of innovations within health systems and team learning, and, on the other hand, with different aspects of the detection and management of intimate partner violence (IPV) within healthcare facilities, research that explores how health innovations that go beyond biomedical issues—such as IPV management—get integrated into health systems, and that focuses on healthcare teams’ learning processes is, to the best of our knowledge, very scarce if not absent. This realist evaluation protocol aims to ascertain: why, how, and under what circumstances primary healthcare teams engage (if at all) in a learning process to integrate IPV management in their practices; and why, how, and under what circumstances team learning processes lead to the development of organizational culture and values regarding IPV management, and the delivery of IPV management services. Methods: This study will be conducted in Spain using a multiple-case study design. Data will be collected from selected cases (primary healthcare teams) through different methods: individual and group interviews, routinely collected statistical data, documentary review, and observation. Cases will be purposively selected in order to enable testing the initial middle-range theory (MRT). After in-depth exploration of a limited number of cases, additional cases will be chosen for their ability to contribute to refining the emerging MRT to explain how primary healthcare learn to integrate intimate partner violence management. Discussion: Evaluations of health sector responses to IPV are scarce, and even fewer focus on why, how, and when the healthcare services integrate IPV management. There is a consensus that healthcare professionals and healthcare teams play a key role in this integration, and that training is important in order to realize changes. However, little is known about team learning of IPV management, both in terms of how to trigger such learning and how team learning is connected with changes in organizational culture and values, and in service delivery. This realist evaluation protocol aims to contribute to this knowledge by conducting this project in a country, Spain, where great endeavours have been made towards the integration of IPV management within the health system.

Mapping and exploring health systems' response to intimate partner violence in Spain

Background: For a comprehensive health sector response to intimate partner violence (IPV), interventions should target individual and health facility levels, along with the broader health systems level which includes issues of governance, financing, planning, service delivery, monitoring and evaluation, and demand generation. This study aims to map and explore the integration of IPV response in the Spanish national health system. Methods: Information was collected on five key areas based on WHO recommendations: policy environment, protocols, training, monitoring and prevention. A systematic review of public documents was conducted to assess 39 indicators in each of Spain’s 17 regional health systems. In addition, we performed qualitative content analysis of 26 individual interviews with key informants responsible for coordinating the health sector response to IPV in Spain. Results: In 88% of the 17 autonomous regions, the laws concerning IPV included the health sector response, but the integration of IPV in regional health plans was just 41%. Despite the existence of a supportive national structure, responding to IPV still relies strongly on the will of health professionals. All seventeen regions had published comprehensive protocols to guide the health sector response to IPV, but participants recognized that responding to IPV was more complex than merely following the steps of a protocol. Published training plans existed in 43% of the regional health systems, but none had institutionalized IPV training in medical and nursing schools. Only 12% of regional health systems collected information on the quality of the IPV response, and there are many limitations to collecting information on IPV within health services, for example underreporting, fears about confidentiality, and underuse of data for monitoring purposes. Finally, preventive activities that were considered essential were not institutionalized anywhere. Conclusions: Within the Spanish health system, differences exist in terms of achievements both between regions and between the areas assessed. Progress towards integration of IPV has been notable at the level of policy, less outstanding regarding health service delivery, and very limited in terms of preventive actions.

La respuesta sanitaria a la violencia de género. ¿Adaptar el sistema o medicalizar la violencia? estudio cualitativo

Antecedentes/Objetivos: El sistema sanitario puede jugar un papel clave en la prevención y atención de la violencia de género (VG), debido a las consecuencias para la salud de la violencia y al hecho de que las mujeres afectadas acceden a los servicios de salud con mayor frecuencia que a otros servicios públicos. El objetivo de este estudio es analizar cómo entienden los profesionales encargados de la coordinación de los programas de VG en los servicios regionales de salud la integración de la respuesta sanitaria a este problema en el Sistema Nacional de Salud español. Métodos: Estudio cualitativo en el que se realizaron 26 entrevistas individuales a informantes clave del nivel gerencial, 23 de las 17 comunidades autónomas y 3 del nivel nacional, entre julio de 2012 a marzo de 2013. Las transcripciones se importaron al software informático Atlas.ti-5 y se analizaron de acuerdo al método de la Teoría Fundamentada. Resultados: Se desarrolló un modelo conceptual que explica los esfuerzos y retos cuando se intenta integrar la respuesta a la VG en el sistema sanitario, que permanece fuertemente biomedicalizado. Emergieron una categoría central: Integrando respuestas a problemas no biomédicos en sistemas de salud biomédicos, el caso de la VG; y 4 categorías relacionadas con la central: La VG es un problema complejo que genera resistencia o activismo; El mandato para integrar una respuesta sanitaria a la violencia: una prioridad no siempre priorizada; El sistema sanitario español, respetuoso con la autonomía de los profesionales, biomédico y familiarista; y Desarrollando respuestas a la integración de la violencia: adaptar el sistema de salud o medicalizar la violencia. Conclusiones: Integrar el abordaje de la VG en un sistema de salud biomédico es un reto. Los hallazgos sugieren que la motivación individual puede compensar las deficiencias en el sistema existente, en términos de ser más centrada en la persona y, por lo tanto, fomentar una fuerte relación de confianza. Sin embargo, la sostenibilidad de los procesos dependientes en la motivación e interés individual es difícil si no hay una estructura organizativa que los respalde.
