Published: October 2017

Introdução: O crescente uso das redes sociais na internet por agentes políticos e eleitores configuram a entrada do país nos moldes de uma cultura digital participativa, constituindo-se uma esfera rica para o desenvolvimento de pesquisas sobre o desempenho dos candidatos em meio digital e a participação política do cidadão. O presente trabalho se propõe a verificar o desempenho no Facebook do candidato à Prefeitura de Maceió, Rui Palmeira nas eleições de 2016. Método: A pesquisa tem caráter exploratório, de abordagem mista e cunho descritivo, com coleta de dados realizada pela ferramenta Netlytic e a análise por meio da categorização das publicações e compreensão das interações em sua página no Facebook. Resultados: A maior parte das postagens realizadas diz respeito à Agenda do candidato (24,6%), a Agradecimentos/Cumprimentos (16,7%) e Propostas (15,8%). Apesar disso, as postagens que tiveram maior interação dos eleitores são as de Cunho Pessoal, que compreenderam apenas 5,7% do total de postagens. Conclusão: As mídias sociais começaram a ser ocupadas e tratadas com relevância no tocante ao cenário político, o que pode ser notado pela diversificação das categorias de postagens. O candidato em questão conseguiu compreender algumas premissas da Web 2.0 quanto à interação e colaboração, no entanto, é necessário destacar que há um longo caminho a percorrer no que tange à responsividade do candidato e interação direta com os eleitores via a ferramenta.

Published: October 2017

A Cartografia Social afigura-se em um importante procedimento metodológico voltado para a construção do conhecimento territorial a partir da valorização dos múltiplos saberes dos sujeitos sociais. Este artigo objetiva tecer uma teorização baseada em práticas voltadas à construção de mapeamentos sociais por agricultores e agricultoras do Município de Apodi - RN sendo elencados um conjunto de conflitos socioambientais vivenciados no território. Os procedimentos metodológicos tiveram referencial teórico fundamentado nos estudos de Gorayeb, Meireles, Silva (2015); Bargas, Cardoso, (2015); Cubides (2009), dentre outros, onde os procedimentos técnicos consistiram na utilização da técnica de overlay para a elaboração dos mapas sociais. Diante do exposto pode-se afirmar que, i) a Cartografia Social propiciou o aprofundamento no reconhecimento das características, conflitos, problemas e proposições voltadas à garantia de direitos sociais das diferentes regiões existentes no município de Apodi, ii) houve a fortificação das relações comunitárias durante as atividades voltadas à formação geocartogáfica e, iii) foi perceptível integração entre os saberes populares e o conhecimento cientifico que culminaram na construção dos mapas sociais sob o prisma da coletividade.

A relação do turismo global com os nativos determina a produção desse trabalho, no o qual tem o objetivo geral de discutir os efeitos produzidos pelo turismo na comunidade Barra Grande, no município de Cajueiro da Praia, no Norte do Piauí. Ademais, busca-se analisar como o modelo de turismo globalizado atua sobre os nativos, a partir dos aspectos positivos e negativos da atividade. A metodologia partiu do contato direto por meio de uma pesquisa de campo qualitativa, realizada com a aplicação de questionários fechados, finalizando com a observação simples. A pesquisa identificou que a atividade turística tem impactado a vida dos nativos, provocando alterações nos modos tradicionais de vida, bem como nas atividades laborais e no acesso à renda, uma vez que o setor de turismo não tem admitido os nativos nos postos de empregos gerados. Desste modo, percebem-se deficiências quanto às formas de desenvolvimento do turismo, tendo em vista que a atividade tem beneficiado capitalistas , e potencializando a desigualdade e exclusão social, gerando relações conflituosas entre turistas, nativos e empresários. Assim, à para melhor gestão do turismo local, é imprescindível que haja uma maior participação dos nativos na organização, na participação e no desenvolvimento da atividade.

Published: October 2017

O estudo das fragilidades ambientais é essencial para a verificação da suscetibilidade do ambiente aos processos geomorfológicos. Nessa perspectiva, o principal objetivo dessa pesquisa foi mapear e interpretar a fragilidade ambiental potencial e emergente da cidade de Santa Maria/RS, com a finalidade de contribuir para o planejamento urbano e ambiental da cidade. O método de pesquisa aplicado à determinação dos graus de fragilidades ambientais, potencial e emergente teve como embasamento a metodologia do mapeamento da paisagem em Unidades Ecodinâmicas Instáveis e Unidades Ecodinâmicas Estáveis propostas por Ross (1994). Os resultados da pesquisa mostraram que, na cidade de Santa Maria/RS, existem diversos graus de fragilidades ambientais potenciais, desde o muito fraco até o muito forte, devido às características dos elementos físicos que compõem a paisagem e essas fragilidades tornam-se emergentes, em diferentes graus, desde o muito fraco até o muito forte, dependendo do nível de alteração da paisagem. A classe de fragilidade ambiental emergente mais representativa da cidade de Santa Maria/RS é a classe fraca, distribuída principalmente nos setores oeste, sul e leste da cidade, os quais se configuram como vetores de crescimento urbano e no setor norte, cuja vegetação é de florestas densas. No entanto, os locais que apresentam graus de fragilidade ambiental emergente forte e muito forte são os causam preocupação em termos de suscetibilidade aos desastres geomorfológicos desencadeados pelos processos da dinâmica de encostas e da dinâmica fluvial, uma vez que esses processos acarretam riscos para os habitantes desses locais, podendo causar danos materiais e perdas de vidas.
ALUÍSIO AZEVEDO E O DETERMINISMO SOCIAL NA CONSTRUÇÃO DO ESPAÇO URBANO: REFLEXÕES À LUZ DA GEOGRAFIA HUMANISTA E CULTURAL
Authors: Moreira Jorgeanny de Fátima Rodrigues
Published: October 2017

Nesse artigo propõe-se a leitura das três mais importantes obras de Aluísio Azevedo, O Cortiço, Casa de Pensão e O Mulato, a partir da geografia humanista e cultural. Com base em uma análise voltada para os aportes teórico-conceitual do existencialismo sartreano far-se-á um contraponto à literatura de Azevedo, que foi influenciada pelo cientificismo, darwinismo e determinismo social. Nas obras listadas o autor descrevia a degradação do meio urbano brasileiro, em que a miséria e a pobreza eram grandes responsáveis pela degradação moral do homem. Em decorrência, atitudes ligadas a violência, promiscuidade e vícios justificavam-se pela natureza das relações sociais no espaço degradado. Com isso pretende-se contribuir com reflexões acerca da produção do espaço urbano e social brasileiro, e as explicações científicas a que eram dadas na época, em que o positivismo e o cientificismo apresentavam um sentido generalizado nas ciências e na literatura do país. A interpretação, aqui exposta, a partir das leituras de Jean-Paul Sartre tem o intuito de explicar os conflitos sociais a partir do homem, em detrimento do meio. Levar-se-á em consideração as ações humanas como próprios de suas experiências e essência, ao contrário da literatura naturalista que considera a “natureza” humana. Tal estudo foi subsidiado, por uma metodologia qualitativa de teor descritiva e analítica.
CARACTERÍSTICAS E CONTRADIÇÕES DAS CIDADES NO CONTEXTO DO AGRONEGÓCIO: UMA ANÁLISE DAS CIDADES DE SAPEZAL (MT) E CHAPADÃO DO SUL (MS)
Authors: Melo Danilo Souza
Published: October 2017

O processo de ocupação do antigo Mato Grosso promovido pelo Estado resultou na transferência de grandes quantidades de terras para capitalistas que posteriormente fundaram núcleos urbanos para dar suporte à venda de terras. Alguns destes núcleos ganharam destaque pelo grande crescimento econômico resultante do agronegócio, estas cidades passaram a ser chamadas por alguns pesquisadores de “Cidades do Agronegócio”. Este trabalho tem como objetivo discutir as características e contradições resultantes da reprodução da agricultura capitalista nas cidades de Sapezal (MT) e Chapadão do Sul (MS) no contexto das chamadas cidades do agronegócio. Para tanto, utilizamos uma metodologia baseada em revisão bibliográfica, analise de dados estatísticos e trabalhos de campo com a utilização de entrevistas. Neste trabalho foi possível compreender que a cidade e o campo compõem um território do capital, no qual, intensas contradições são resultantes do seu desenvolvimento.
OS CASSACOS MIGRANTES DE TAMBOARA – PR: REFLEXOS DA MODERNIZAÇÃO CONSERVADORA
Authors: Ribeiro Vitor Hugo
Published: October 2017

Este artigo, resultado de um trabalho de doutorado em Geografia, objetivou-se em estudar a mobilidade de trabalhadores e trabalhadoras rurais migrantes do município de Tamboara – PR, levando-se em consideração algumas características sociais bem como as motivações desse fluxo populacional. Averiguou-se, por meio de trabalho de campo, que a exclusão social por que passam esses trabalhadores são reflexos da modernização conservadora e do processo de reestruturação produtiva do capital em nosso país. Tais elementos foram desencadeadores de uma força de trabalho rural de baixa escolarização e excludente do mercado de trabalho formal, que tem adquirido, por meio dos fluxos migratórios, as oportunidades de conquistarem melhores condições de vida e anseios.

Authors: Elzakil Maisa , Gareeballah Awadia , Gameraddin Moawia , Burai Mowada , Alagab Fathelrehman
Published: October 2017

Background: Thyroid gland morphology and disorders were affected with chronic kidney diseases (CKD). The study aims to assess thyroid gland disorders and morphology in patients with CKD on regular hemodialysis.Materials and methods: A cross-sectional study included 71 participants divided into two groups. The study group included 51 patients with known chronic kidney disease on hemodialysis and healthy group included 20 participants. The exclusion criteria were thyroid disorders. The thyroid gland was scanned with ultrasound using a 7 MHz probe.Results: The thyroid is enlarged in 21.57% of patients and heterogeneous echotexture in 31.4%. The prevalence of thyroid nodules and cysts were 9.8% and 7.8% respectively. A positive linear correlation existed between duration of hemodialysis and thyroid volume. Thyroid volume and echotexture were significantly increased with duration of hemodialysis (p = .001 and .00 respectively). Thyroid nodules and cysts were not significantly correlated with duration of hemodialysis (p = .06 and .28 respectively).Conclusions: In conclusion, enlargement of thyroid gland and heterogeneity of thyroid tissue were the most common morphological changes in patients with chronic renal failure undergoing hemodialysis. The prevalence increased with longer duration of hemodialysis. Periodic ultrasound assessment of thyroid volume and texture are recommended in hemodialyzed patients to avoid complications.

Authors: Abu Raddaha Ahmad H. , Obeidat Arwa , Al Awaisi Huda , Hayudini Jahara
Published: October 2017

Background: Despite worldwide expanding implementation of electronic health record (EHR) systems, healthcare professionals conducted limited number of studies to explore factors that might facilitate or jeopardize using these systems. This study underscores the impact of nurses’ opinions, perceptions, and computer competencies on their attitudes toward using an EHR system.Methods: With randomized sampling, a cross-sectional exploratory design was used. The sample consisted of 169 nurses who worked at a public teaching hospital in Oman. They completed self-administered questionnaire. Several standardized valid and reliable instruments were utilized.Results: Seventy-four percent of our study nurses had high positive attitudes toward the EHR system. The least ranked perception scores (60.4%) were linked to perceiving that suggestions made by nurses about the system would be taken into account. Nurses who reported that the hospital sought for suggestions for customization of the system [OR: 2.54 (95% CI: 1.09, 5.88), p = .03], who found the system as an easy-to-use clinical information system [OR: 6.53 (95% CI: 1.72, 24.75), p = .01], who reported the presence of good relationship with the system’s managing personnel [OR: 3.59 (95% CI: 1.13, 11.36), p = .03] and who reported that the system provided all needed health information [OR: 2.97 (95% CI: 1.16, 7.62), p = .02] were more likely to develop high positive attitudes toward the system.Conclusions: To better develop plans to foster the EHR system’s use facilitators and overcome its usage barriers by nursing professionals, more involvement of nurses in system’s customization endeavors is highly suggested. When the system did not disrupt workflows, it would decrease clinical errors and expand nursing productivity. In order to maximize the utilization of the system in healthcare delivery, future research work to investigate the effect of the system on other healthcare providers and inter-professional communications is pressingly needed.
Patterns, Trends and Policy Implications of Private Spending on Skills Development in Mexico and the United States
Authors: Székely Miguel , Mendoza Pamela
Published: October 2017

This paper explores families’ investment in skills development through education in a high-inequality, low-educationquality country such as Mexico, comparing it to a lower-inequality, higher-quality education country such as theUnited States. The paper uses a series of Household Income and Expenditure Surveys for both countries spanningaround 20 years and different methodological approaches. Of particular interest is the analysis of educationexpenditure patterns along the income distribution. Policy implications for both cases are discussed. While in Mexicostimulating private spending in education through public resources might be regressive, the contrary might be thecase in the United States.
An Interpretation of Mary in the Shadow of Colonialism in Doris Lessing’s—The Grass is Singing
Authors: Zhang Yechun
Published: October 2017

Doris Lessing, one of the most popular writers of British literature in the second half of the twentieth century, is famous for her changeable styles of works and different perspectives all over the world. Reviewing from Doris Lessing’s works, Marginal Man is the main clue in her literary creation. Most of characters she created in her works are living in the cracks of changeable era and cultural transformation. From the race of blacks and whites to the free female under the colonial background in 1950s and 60s; and then from the spiritual alienation under culture shock in 1970s and 80s to the difficult living conditions of the middle-aged and the aged in her later works, all of these characters are the unique microcosm of the Marginal Man created by means of blending Lessing’s own experiences and emotional imagery. All of these novels transmit the rise and fall of deep culture and the sense of vicissitudes of life.This thesis elaborates Mary, a Marginal Man in Doris Lessing’s The Grass is Singing from three points of view—Mary’s drifting, Mary’s Constraints and Fears, Mary’s Fleeing and Awakening. From it, we can understand that fleeing as her surviving way is to get rid of the shackles of life, moreover she bares the double loss coming from the external world and the innermost, and then she eventually makes for resistance and comes to her spiritual salvation in order to seek for her spiritual home. This thesis makes a good reflection on the real living conditions of marginal groups and guides people to establish correct social values to realize the social problems caused by marginal people and make some measures to solve some of them.

Published: October 2017

We study some algebraic properties of Toeplitz operators  with radial and quasi homogeneous symbols on the pluriharmonic Fock space over $\mathbb{C}^{n}$. We determine when the product of two Toeplitz operators with radial symbols is a Toeplitz operator, the zero-product problem for the product of two Toeplitz operators.  Next we characterize the commutativity of Toeplitz operators with quasi homogeneous symbols and finally we study finite rank of the product of Toeplitz operators with quasi homogeneous symbols.

Authors: Aneas Assumpta , Rubio María José , Vilà Ruth
Published: October 2017

El objetivo de la investigación presentada ha sido conocer la percepción que tienen los alumnos que se encuentran en cuarto curso del grado de Pedagogía de la Universidad de Barcelona sobre sus competencias transversales antes y después de haber realizado la asignatura de Prácticas Externas con el uso de un portafolios digital. Mediante un diseño de pretest y postest, se ha desarrollado una investigación por encuesta con la cohorte de alumnos que empezaron el grado durante el curso 2011-2012 y que lo finalizaron durante el curso 2014-2015. El instrumento de recogida de datos ha sido el Cuestionario de apreciación de desempeño de competencias (12 ítems Likert-6 puntos según el nivel de aplicación de las competencias). Después de que los estudiantes hayan participado en las prácticas externas y de que hayan utilizado el portafolios digital en su evaluación, perciben que han conseguido un mayor nivel de autonomía en todas las competencias transversales. Se identifican dos perfiles de alumnado: un grupo que inicialmente tenía una percepción sobre su desarrollo competencial bastante bajo y que, en gran medida, mejora su percepción al finalizar la experiencia con portafolios digital, y otro grupo que tenía autopercepciones de un mayor desarrollo competencial al inicio y que, al finalizar, solo las mejora ligeramente.
Los entornos activo-colaborativos de aprendizaje como buenas prácticas en el desarrollo de competencias transversales en la formación profesional de la Comunidad Autónoma del País Vasco
Authors: Eizagirre Sagardia Ana , Altuna Urdin Jon , Fernández Fernández Idoia
Published: October 2017

Este artículo analiza el modo en que las orientaciones prescriptivas generales sobre competencias transversales se están llevando realmente a la práctica en los centros de formación profesional de la Comunidad Autónoma Vasca. Se realiza un estudio de caso en el que se transita desde una detección previa de carácter cuantitativo hasta un análisis cualitativo de las prácticas en las que las citadas competencias han sido desarrolladas con éxito según la percepción del profesorado, del alumnado y de los equipos directivos implicados. Como resultado, se han identificado tres niveles de sistematización y desarrollo institucional de las competencias transversales: el individual, el de ciclo y el de centro. La comparación entre estas tipologías resultantes revela que las prácticas innovadoras a nivel de ciclo, y más en concreto en los ciclos de alto rendimiento (ETHAZI), concentran unas características que representan un salto cualitativo en la concepción, el desarrollo metodológico y la evaluación de las citadas competencias, y que, por tanto, pueden servir de guía para ir superando los obstáculos que, a nivel práctico, encuentra el desarrollo real de las competencias transversales en el ámbito de la formación profesional.

Published: October 2017

La sociedad del conocimiento es una transición de las economías industriales a las economías fundadas en el saber, que están basadas en inversiones en educación, formación, investigación y desarrollo. Por ese motivo, interesa analizar la trayectoria de egreso y los perfiles profesionales de los egresados con base en la producción académica, la satisfacción con las competencias adquiridas, el programa educativo y la institución, así como, por medio del análisis estadístico de regresión lineal, dar respuesta a la pregunta siguiente: ¿en qué medida la trayectoria de egreso se distingue por su producción académica? Los datos que se utilizan son de dieciocho universidades e instituciones de educación superior (IES) mexicanas. Las generaciones del estudio comprenden los años que van de 2006 a 2013. Se encontró que los egresados que realizaban producción académica constituían el 13,3% del total; que el 12,9% de sus productos contaba con registro de la propiedad intelectual; que el 10,5% de ellos había participado en proyectos de investigación, había difundido el conocimiento por medio de su participación en conferencias, ponencias y talleres en eventos académicos, había colaborado con colegas y pertenecía al Sistema Nacional de Investigadores en México; que el 51,7% había impartido clases, y que el 50,9% había dirigido tesis. Estos resultados determinan la formación en el posgrado por competencias científicas.

En este trabajo, se han analizado las orientaciones motivacionales en una muestra de estudiantes universitarios. Durante tres cursos académicos, participaron en ella 675 alumnos del grado de Maestro en Educación Infantil y Primaria de la Universidad de Castilla-La Mancha, un 92% de los cuales eran mujeres y entre todos tenían una edad media de 22 años. La motivación fue evaluada mediante el Cuestionario de Estrategias de Aprendizaje y Motivación (CEAM II). Se pretenden conocer las subescalas motivacionales de los estudiantes y la repercusión que sobre estos tiene compaginar sus estudios de grado con o sin un trabajo remunerado. Los datos son expuestos mediante medidas de tendencia central, de dispersión y de posición. Posteriormente, se realiza la comparación de medias independientes de tipo no paramétrico. Se contrasta la hipótesis sobre las diferencias motivacionales entre el grupo de estudiantes que trabaja y el que no trabaja. Los resultados muestran diferencias significativas en las subescalas Orientación a metas extrínsecas y Autoeficacia para el rendimiento entre los universitarios que tienen un trabajo remunerado y los que no. Como conclusión, vemos que, para lograr una intervención docente eficaz, es necesario conocer a nuestros alumnos y a sus metas para ayudarles a lograr el éxito académico.
Mixed-Phenotype Acute Leukemia: Diagnostic Criteria and Pitfalls
Authors: Charles Nathan J. , Boyer Daniel F.
Published: October 2017

Mixed-phenotype acute leukemia (MPAL) is a heterogeneous category in the World Health Organization classification that comprises acute leukemias with discrete admixed populations of myeloid and lymphoid blasts (“bilineal”) or with extensive coexpression of lymphoid and myeloid markers in a single blast population (“biphenotypic”). Flow cytometric findings suggestive of MPAL are often met with consternation by pathologists and oncologists alike, owing to unfamiliarity with the disease and uncertainty about how MPAL fits into established paradigms for treatment of acute leukemia. The purpose of this review is to explain the diagnostic criteria for MPAL, summarize its biological and clinical features, and address common diagnostic pitfalls of these unusual leukemias.
Myxoinflammatory Fibroblastic Sarcoma: Review and Update
Authors: Lucas David R.
Published: October 2017

Myxoinflammatory fibroblastic sarcoma is a rare soft tissue tumor with most occurring in the distal extremities of adult patients. It has a high rate of local recurrence and a low rate of metastasis. Because it may appear benign on clinical examination, and because the microscopic features are generally underrecognized, it is often inadequately treated and misdiagnosed. In this review, based upon experience and that of the literature, the intent is to highlight salient clinicopathologic features, detail the broad microscopic spectrum including high-grade aggressive variants, review the molecular features, and discuss its relation to hemosiderotic fibrolipomatous tumor.

This article seeks to demonstrate the evolution of the issues related to the ombudsman's offices complaints of banks, considering the size and type of control in Brazil. An exploratory research was carried out with a non-probabilistic sample of 26 public, domestic private and foreign banks. The data was collected from 1.377 complaints related to the ombudsman's offices of these banks, ended from the 1st semester of 2008 to the 1st semester of 2011 and released by the Central Bank of Brazil. Data analysis employed descriptive statistics, inferential statistics and Multiple Correspondence Analysis. It was ascertained that the complaint issue 'Ombudsman' predominated in the complaints occurrences until the 1st semester of 2009 while other complaint issues prevailed from the 2nd semester of 2009. The issues 'Term Breach' and 'Others and Dial Direct Free' were conditioned mostly to middle-size banks and domestic private ones, and 'Customer Service' was associated mostly to very large banks that are public. Results can contribute to enhance the banks' ombudsman's offices regulatory duties, and also can contribute to understand the implementation of socially responsible actions of banks to meet both customers and users as banks' stakeholders in Brazil.

This article presents the development, factor structure and discussion of a model for assessing the appropriate corporate environmental responsibility to agribusiness production chain. The empirical research was conducted with companies in the Alto Paranaíba, Minas Gerais and the data collected through questionnaire was used and scale. With the factor analysis extracted five factors: Commitment and environmental activity (COMAMB = 3.20), Environmental impacts (GIMA = 4.13), Education and environmental awareness (ECAM = 3.52), Involvement with stakeholders (ENVOLV = 3.69) and Resource economics (ECON = 4.23). The overall index of corporate environmental responsibility was 0.6885. It was observed that the companies analyzed, on average, do not care about education and environmental awareness and have a low level of commitment to actions for the preservation and protection of the environment. However, they seek to maintain an efficient management of environmental impacts and which involve such issues with their stakeholders. And so, perform 'green economy' and 'green marketing' of their activities. Finally, the debate that corporate environmental responsibility is a strategy where the companies operate, guided by a strategic and economic rationality.

This paper presents the development of an ICT framework for the management, processing and analysis of large-scale Brazilian cancer data. This was a qualitative and descriptive study conducted at Brazilian National Cancer Institute (INCA). The benefits derived from the framework implementation, so far, are: real-time knowledge access; patient’s focus and satisfaction; enhanced knowledge transfer and diffusion of best health care practices; reduction in treatment costs; relief of the INCA’s labor shortage; and finally speediness of cancer diagnosis and enhanced quality of both diagnosis and data used in epidemiological studies. The study also identifies the critical aspects that must be observed by the Brazilian health organizations in early stages of development of BI systems and thus contributes to the faster adoption of such systems.
Predicting Student Achievement Using Measures of Teachers' Knowledge for Teaching Geometry
Authors: Mohr-Schroeder Margaret , Ronau Robert N. , Peters Susan , Lee Carl W. , Bush William S.
Published: October 2017

This article describes the development and validation of two forms of the Geometry Assessments for Secondary Teachers (GAST), which were designed to assess teachers' knowledge for teaching geometry. Both forms were developed by teams of mathematicians, mathematics educators, psychometricians, and secondary classroom geometry teachers. Predictive validity for the GAST assessment was explored by observing and testing 157 teachers as well as administering pre– and post–tests to 3,698 students. The reliability coefficient for both GAST assessment forms was acceptable (r = .79). GAST assessment scores explained a statistically significant but small amount of the variance of student scores, demonstrating an effect that was greater than the number of years of teaching experience but smaller than the effect of having an advanced degree.

‘Ontology’ and Terminological Frameworks: an Overview of Issues and Term(s)
Authors: Leonardi Natascia
Published: October 2017

This paper addresses the question of the protean nature of ‘ontology’, with special attention paid to its use within the domain of terminology theories and applications. This term is widely used nowadays within various disciplines for designating different types of organising relational frameworks. Yet, its designations remain unvaried and, in this way, it causes ambiguity. The multifaceted nature of the so-called ‘ontology’ hinders the possibility of providing an unambiguous definition. This is mainly due to the multi- and interdisciplinary dimension of this notion, which is outlined here through an overview of its application within philosophy, information science, and linguistic disciplines.The reference model of ontology that is applied nowadays in various disciplines corresponds to an object, or more precisely, to various types of objects which are all based on a relational framework, and are used for organising different types of knowledge units. This view differs from the original value of ontology that was shaped within philosophy as a purely theoretical model, a global and universally-valid abstract classification of reality. Therefore, it seems appropriate that this term should acquire greater precision especially when it is used within the domain of terminology.
Applying Ontologies to Terminology: Advantages and Disadvantages
Authors: Durán-Muñoz Isabel , Bautista-Zambrana María Rosario
Published: October 2017

This paper aims at discussing the main advantages that ontologies bring to the field of terminology and its users, focusing on different aspects and needs. Throughout the paper ontologies are acknowledged as a valuable resource to improve quality of terminological projects as well as the content of terminologies, but it also seems appropriate to define the concept of ontologies more precisely and to outline their benefits and limitations. To do so, we firstly discuss the multidisciplinarity of ontologies and the main recent uses within different disciplines. Secondly, we focus on terminology studies and theories and depict the evolution of this resource in the terminology field during the last decades, which has brought about the appearance of new methodologies and applications. Next, we put forward the advantages that ontologies bring to terminology in general and to several linguistic phenomena in particular (multidimensionality, for example) so as to shed some light on their importance in this field and, finally, we conclude with the discussion of significant drawbacks encountered, along with some final remarks about the use of ontologies in terminology work.

Published: October 2017

Créé en 1991 par le Carrefour Culturel d’Arnaud-Bernard, le repas-de-quartier a pour objectif de favoriser le vivre-ensemble et de faire face à la tentative d’embourgeoisement du quartier organisée par la municipalité de Toulouse. L’analyse du temps spontané, éphémère et discontinu des repas-de-quartier questionne la création de liens sociaux, mais également la réalisation dans le temps long d’une manifestation de la démocratie directe : une participation citoyenne créatrice d’une communauté productrice de son lieu de vie. L’accessibilité des sources conduit le chercheur à une pratique interdisciplinaire afin d’analyser cet évènement singulier à plusieurs échelles.
Penser l’évêque au haut Moyen Âge selon une dimension régionale : le cas particulier de l’Austrasie. Bilan, perspectives et champs de recherches
Authors: Rolland Jean-Noël
Published: October 2017

L’Austrasie est une échelle régionale pour l’historien du haut Moyen Âge. Or, ce royaume du Nord-Est de la Gaule issu des partages et des conflits qui suivirent la mort de Clovis († 511) est très fuyant tant dans les sources que dans ses limites changeantes. En lien avec l’épiscopat franc, qui, tout comme l’élite aristocratique, serait le liant principal de cet espace éphémère, cette contribution propose un bilan historiographique ainsi que des pistes de recherche.
Élargissement d’échelles et nouveaux regards sur la Résistance française pendant la Seconde Guerre mondiale
Authors: Houle Vincent
Published: October 2017

Depuis 1945, les historiens de la Résistance française ont surtout cherché à déconstruire le phénomène résistant par la sélection d’échelles d’analyse qui mettent l’accent sur la singularité de leurs objets d’études. Or, un renouveau historiographique, dont la caractéristique fondamentale est l’élargissement des échelles d’analyse, permet d’étudier la Résistance dans sa globalité et rend possible une définition nouvelle de la Résistance française. Des pistes que ce changement de perspective permet d’explorer, le traitement des sujets internationaux dans l’ensemble de la presse clandestine révèle des dynamiques de développement communes à la majorité des courants résistants.
Defining the location of promoter-associated R-loops at near-nucleotide resolution using bisDRIP-seq
Authors: Dumelie Jason G , Jaffrey Samie R
Published: October 2017

R-loops are features of chromatin consisting of a strand of DNA hybridized to RNA, as well as the expelled complementary DNA strand. R-loops are enriched at promoters where they have recently been shown to have important roles in modifying gene expression. However, the location of promoter-associated R-loops and the genomic domains they perturb to modify gene expression remain unclear. To resolve this issue, we developed a bisulfite-based approach, bisDRIP-seq, to map R-loops across the genome at near-nucleotide resolution in MCF-7 cells. We found the location of promoter-associated R-loops is dependent on the presence of introns. In intron-containing genes, R-loops are bounded between the transcription start site and the first exon-intron junction. In intronless genes, the 3' boundary displays gene-specific heterogeneity. Moreover, intronless genes are often associated with promoter-associated R-loop formation. Together, these studies provide a high-resolution map of R-loops and identify gene structure as a critical determinant of R-loop formation.

PRDM9 binding localizes almost all meiotic recombination sites in humans and mice. However, most PRDM9-bound loci do not become recombination hotspots. To explore factors that affect binding and subsequent recombination outcomes, we mapped human PRDM9 binding sites in a transfected human cell line and measured PRDM9-induced histone modifications. These data reveal varied DNA-binding modalities of PRDM9. We also find that human PRDM9 frequently binds promoters, despite their low recombination rates, and it can activate expression of a small number of genes including CTCFL and VCX. Furthermore, we identify specific sequence motifs that predict consistent, localized meiotic recombination suppression around a subset of PRDM9 binding sites. These motifs strongly associate with KRAB-ZNF protein binding, TRIM28 recruitment, and specific histone modifications. Finally, we demonstrate that, in addition to binding DNA, PRDM9's zinc fingers also mediate its multimerization, and we show that a pair of highly diverged alleles preferentially form homo-multimers.

Limiting the juvenile phase and reducing tree size are the two main challenges for breeders to improve most fruit crops. Early maturation and dwarf cultivars have been reported for many fruit species. “Early mature” and low vigor walnut genotypes were found among seedlings of Persian walnut. Nine microsatellite markers were used to evaluate genetic diversity among “Early Mature” Persian walnut accessions and provide a comparison with “normal growth” accessions. Six maturation related characteristics were also measured in “Early Mature” samples. Phenotypic traits and diversity indices showed relatively high levels of genetic diversity in “Early Mature” seedlings and indicated high differentiation between individuals. Seedling height, the most diverse phenotypic trait, has an important role in the clustering of “Early Mature” accessions. The “Early Mature” type had higher number of alleles, number of effective allele, and Shannon index compared to the “Normal Growth” group. The two types of studied walnuts had different alleles, with more than half of produced alleles specific to a specific group. “Early Mature” and “Normal Growth” walnuts had 27 and 17 private alleles, respectively. Grouping with different methods separated “Early Mature” and “Normal Growth” samples entirely. The presence of moderate to high genetic diversity in “Early Mature” walnuts and high genetic differentiation with “Normal Growth” walnuts, indicated that “Early Mature” walnuts were more diverse and distinct from “Normal Growth” samples. Moreover, our results showed SSR markers were useful for differentiating between “Early Mature” and “Normal Growth” walnuts. A number of identified loci have potential in breeding programs for identification of “Early Mature” walnuts at the germination phase.

Households are an important location for the transmission of communicable diseases. Social contact between household members is typically more frequent, of greater intensity, and is more likely to involve people of different age groups than contact occurring in the general community. Understanding household structure in different populations is therefore fundamental to explaining patterns of disease transmission in these populations. Indigenous populations in Australia tend to live in larger households than non-Indigenous populations, but limited data are available on the structure of these households, and how they differ between remote and urban communities. We have developed a novel approach to the collection of household structure data, suitable for use in a variety of contexts, which provides a detailed view of age, gender, and room occupancy patterns in remote and urban Australian Indigenous households. Here we report analysis of data collected using this tool, which quantifies the extent of crowding in Indigenous households, particularly in remote areas. We use these data to generate matrices of age-specific contact rates, as used by mathematical models of infectious disease transmission. To demonstrate the impact of household structure, we use a mathematical model to simulate an influenza-like illness in different populations. Our simulations suggest that outbreaks in remote populations are likely to spread more rapidly and to a greater extent than outbreaks in non-Indigenous populations.
The Role of Uncertainty in Estimating Lead/Lag Relationships in Marine Sedimentary Archives: A Case Study From the Tropical Pacific

Understanding the mechanisms behind any changes in the climate system often requires establishing the timing of events imprinted on the geological record. However, these proxy records are prone to large uncertainties, which may preclude meaningful conclusions about the relative timing of events. In this study, we put forth a framework to estimate the uncertainty in phase relationships inferred from marine sedimentary records. The novelty of our method lies in the accounting of the various sources of uncertainty inherent to paleoclimate reconstruction and timing analysis. Specifically, we use a Monte Carlo process allowing sampling of possible realizations of the time series as functions of uncertainties in time, the climate proxy, and the identification of the termination timing. We then apply this technique to 15 published sea surface temperature records from the equatorial Pacific to evaluate whether we observed any significant changes in the termination timing between the east and the west. We find that the uncertainty on the relative timing estimates is on the order of several thousand years and mainly stems from age model uncertainty (90%). However, even small differences in mean termination timings can be detected with a sufficiently large number of samples. Improvements in the dating of sediment records provide an opportunity to reduce uncertainty in studies of this kind.
