Morphologie et évolution des cavernes et formes superficielles dans les quartzites du Roraima
Authors: Galan Carlos , Lagarde J 
Published: April 2017

Cet article décrit les caractéristiques des formes superficielles et des
cavités dans les quartzites précambriens du Groupe Roraima de la i Guyane vénézuélienne et fait suite à la contribution de Pouyllau et Seurin I (cf. Karstologia 1985, n°5). On présente les mécanismes qui interviennent dans leur genèse, en particulier le rôle de la dissolution intergranulaire qui i attaque le ciment de silice authigénique. En surface, le processus de dissolution-désagrégation agit à partir du "réseau de fractures et transforme le sommet des tepuys en champs de crevasses et de tourelles. i La genèse des cavités, notamment i en bordure de falaise (fissures de i décompression), s'accompagne du processus de soutirage ("piping") et d'effondrements (ex : système perte-émergence de la Sima Aonda). L'hypothèse i "hydrothermaliste", envisagée pour la formation de certaines cavités, reste à démontrer. Les surfaces d'érosion étagées du Roraima se sont élaborées au [ cours du Secondaire et du Tertiaire ; le recul des falaises a permis le recoupe¬ ment de cavités très anciennes comme celles du Cerro Autana.

Abstract
Bandon Marsh National Wildlife Refuge, Oregon, completed construction of a large-scale tidal marsh restoration project on the Ni-les'tun Unit within the Coquille River estuary in 2011. To understand the initial effects of restoration construction and establish a baseline for long-term monitoring, we documented the assemblage of fish species 3 y before and 2 y after restoration construction. The overall fish assemblage in the Ni-les'tun Unit was substantially different after restoration construction, with an increased abundance, frequency, and richness of estuarine and diadromous fish species. Threespine Stickleback Gasterosteus aculeatus and species of Sculpin (family Cottidae) dominated the Ni-les'tun Unit and control area in both relative abundance and capture frequency throughout this study. Among salmonids, Coastal Cutthroat Trout Oncorhynchus clarkii and Coho Salmon Oncorhynchus kisutch had the highest frequency of occurrence and relative abundance both before and after restoration construction. Fish occupied newly constructed channels within 2 y. Species found in new channels included freshwater species (e.g., juvenile salmonids), introduced species (e.g., Mosquitofish Gambusia affinis), and estuarine species (e.g., Sculpin, Threespine Stickleback, and Shiner Perch Cymatogaster aggregata). Changes were likely due to improved access and changing habitat created by the reintroduced tidal regime. We recommend long-term monitoring to assess the trajectory of the biological response to the restoration over time.

Abstract. Present and future satellite observations offer great potential for monitoring air quality on a daily and global basis. However, measurements from currently orbiting satellites do not allow a single sensor to accurately probe surface concentrations of gaseous pollutants such as tropospheric ozone. Combining information from IASI (Infrared Atmospheric Sounding Interferometer) and GOME-2 (Global Ozone Monitoring Experiment-2) respectively in the TIR and UV spectra, a recent multispectral method (referred to as IASI+GOME-2) has shown enhanced sensitivity for probing ozone in the lowermost troposphere (LMT, below 3 km altitude) with maximum sensitivity down to 2.20 km a.s.l. over land, while sensitivity for IASI or GOME-2 alone only peaks at 3 to 4 km at the lowest.In this work we develop a pseudo-observation simulator and evaluate the potential of future EPS-SG (EUMETSAT Polar System – Second Generation) satellite observations, from new-generation sensors IASI-NG (Infrared Atmospheric Sounding Interferometer – New Generation) and UVNS (Ultraviolet Visible Near-infrared Shortwave-infrared), to observe near-surface O3 through the IASI-NG+UVNS multispectral method. The pseudo-real state of the atmosphere is provided by the MOCAGE (MOdèle de Chimie Atmosphérique à Grande Échelle) chemical transport model. We perform full and accurate forward and inverse radiative transfer calculations for a period of 4 days (8–11 July 2010) over Europe.In the LMT, there is a remarkable agreement in the geographical distribution of O3 partial columns between IASI-NG+UVNS pseudo-observations and the corresponding MOCAGE pseudo-reality. With respect to synthetic IASI+GOME-2 products, IASI-NG+UVNS shows a higher correlation between pseudo-observations and pseudo-reality, which is enhanced by about 12 %. The bias on high ozone retrieval is reduced and the average accuracy increases by 22 %. The sensitivity to LMT ozone is also enhanced. On average, the degree of freedom for signal is higher by 159 % over land (from 0.29 to 0.75) and 214 % over ocean (from 0.21 to 0.66). The mean height of maximum sensitivity for the LMT peaks at 1.43 km over land and 2.02 km over ocean, respectively 1.03 and 1.30 km below that of IASI+GOME-2. IASI-NG+UVNS also shows good retrieval skill in the surface–2 km altitude range. It is one of a kind for retrieving ozone layers of 2–3 km thickness, in the first 2–3 km of the atmosphere. IASI-NG+UVNS is expected to largely enhance the capacity to observe ozone pollution from space.
Assessment of 222radon progeny loss in long tubing based on static filter measurements in the laboratory and in the field
Authors: Levin Ingeborg , Schmithüsen Dominik , Vermeulen Alex 
Published: April 2017

Abstract. Aerosol loss in air intake systems potentially hampers the application of one-filter systems for progeny-based atmospheric 222radon (222Rn) measurements. The artefacts are significant when air has to be collected via long sampling lines, e.g. from elevated heights at tall tower observatories. Here we present results from a study, determining 222Rn progeny loss from ambient air sampled via 8.2 mm inner diameter (ID) Decabon tubing in the laboratory and from pre-installed 10 mm ID tubing at the Cabauw meteorological tower in the Netherlands. Progeny loss increased steeply with length of the tubing, decreasing sampling efficiency to 66 % for 8.2 mm ID rolled-up tubing of 200 m length at a flow rate of ca. 1 m3 h−1. Preliminary theoretical estimation of the loss yielded a sampling efficiency of 64 % for the same tubing, when taking into account turbulent inertial deposition of aerosol to the walls as well as loss due to gravitational settling. At Cabauw tower, theoretical estimates of the loss in vertical tubing with 10 mm ID and 200 m lengths with flow rate of 1.1 m3 h−1 yielded a total efficiency of 73 %, the same value as observed. 222Rn progeny loss increased strongly at activity concentrations below 1 Bq m−3. Based on our experiments, an empirical correction function for 222Rn progeny measurements when sampling through long Decabon tubing was developed, allowing correction of respective measurements for this particular experimental setting (tubing type and diameter, flow rate, aerosol size distribution) with an estimated uncertainty of 10–20 % for activity concentrations between 1 and 2 Bq m−3 and less than 10 % for activity concentrations above 2 Bq m−3.
O desmonte das políticas de seguridade social e os impactos sobre a classe trabalhadora: as estratégias e a resistência
Authors: Granemann Sara 
Published: April 2017

Tem sido parte da militância de dezenas de docentes – menos do que seria necessário dadas as condições de miserabilidade da classe trabalhadora brasileira – dispor os resultados de suas pesquisas realizadas, sobretudo, em universidades públicas, à disposição daqueles que produzem a riqueza social que mantém as universidades - públicas e privadas - e que, não raro, jamais a conseguem frequentar. Assim, parece-me importante que não somente o empresariado se beneficie dos conhecimentos gerados nas universidades, mas que também as lutas sociais possam se beneficiar do conhecimento produzido pela ciência. Penso que este seminário objetiva, ao propiciar a reflexão de um tema do tempo presente, juntar as necessidades da classe trabalhadora, suas demandas e lutas com as respostas que as pesquisas, a produção de conhecimento, pode ajudar a construir.
Cláusulas relativas na fala espontânea do português do Brasil: Um estudo exploratório baseado no corpus c-oral-brasil

Published: April 2017

Este artigo sistematiza o resultado de investigações exploratórias sobre as cláusulas relativas encontradas no minicorpus de fala espontânea do português do Brasil (PB), etiquetado informacionalmente, extraído do corpus C-ORAL-BRASIL. A seleção dos dados enfocou a identificação dos enunciados nos quais as cláusulas relativas ocorrem. Para essa tarefa, utilizou-se a plataforma DB – IPIC (Panunzi & Gregori, 2011). Em seguida, para triagem das cláusulas relativas, empregou-se a ferramenta computacional AntConc (Anthony, 2013). Para verificação da estrutura informacional dos enunciados, adotou-se o programa WinPitch (Martin, 2004). Os resultados encontrados: (i) corroboram, em termos prosódicos, a diferença entre cláusulas relativas restritivas e relativas não-restritivas – as primeiras ocorrem linearizadas numa mesma unidade informacional e as últimas, padronizadas em mais de uma unidade informacional; e (ii) demonstram que no PB, ambas ocorrem preferencialmente na unidade de COM, e mesmo o padrão informacional preferencial das relativas não-restritivas é resultado da combinação com uma unidade informacional de COM. Além disso, o artigo apresenta uma descrição de cláusulas relativas através de um modelo diagramático que permite alcançar: (i) as relações internas entre cláusula relativa e principal; e (ii) a estrutura informacional definidora da estrutura interna dos enunciados – escopo de realização das cláusulas relativas.
Pesquisa escolar significativa e o bibliotecário: questão essencial para a infoeducação
Authors: Pieruccini Ivete 
Published: April 2017

Introdução: A pesquisa escolar e as dificuldades para torná-la prática qualificada e efetiva no cotidiano da educação de crianças e jovens, em nosso país, é tema recorrente tanto para bibliotecários, como para professores e demais educadores em geral.Objetivo: A partir da problematização de enfoques que apontam causas de ordem pedagógica e metodológica para tais dificuldades, o artigo apresenta e defende a concepção de pesquisa significativa, noção que alarga perspectivas da pesquisa como ato de conhecimento pelos mais variados segmentos infantis e juvenis.Metodologia: Ancorando-se nos fundamentos da Infoeducação, a noção de pesquisa significativa é discutida a partir do papel essencial dos dispositivos informacionais educativos e do bibliotecário, tomado como mediador cultural.Resultados: O estudo mostrou que a pesquisa significativa encontra-se em relação direta com os chamados dispositivos informacionais dialógicos, uma vez que tais instâncias de mediação cultural, por serem orientadas por princípios da apropriação informacional, conforme proposto pela Infoeducação, são capazes de resignificar relações dos sujeitos com a informação e o conhecimento. A ordem resultante das articulações entre ambiente, linguagens, repertórios, práticas informacionais e pedagógicas, nesses dispositivos, constituem mediações que favorecem processos de construção de vínculos entre os sujeitos e o conhecimento, implicando de modo específico os saberes e fazeres do bibliotecário, na contemporaneidade.Conclusões: A noção de pesquisa significativa faz frente a situações em que crianças e jovens realizam buscas esvaziadas de sentido, restituindo ao ato de conhecer seu papel de ação sobre o mundo material e imaterial, objetivo e subjetivo, forma ativa e necessária à apropriação de informação, de sentidos, à construção de identidades. Trata-se de mudança paradigmática que envolve a redefinição de dispositivos informacionais educativos, tais como bibliotecas escolares e públicas (especialmente), tanto quanto o papel do bibliotecário, em contextos educativos.
Malhas da hospitalidade
Authors: Teixeira Faustino 
Published: April 2017

<p>O século XXI depara-se com um dos desafios mais candentes de todos os tempos. Como reagir aos impasses que acompanham o ciclo do Antropoceno, com todas as suas consequências nefastas e necrófilas ? Duas possibilidades se apresentam: a conformidade diante da situação ou a reação crítica e profética, com base na esperança da hospitalidade e do diálogo. Num tempo marcado pelo crescimento dos etnocentrismos, xenofobismos e fundamentalismos, a provocação do diálogo e da acolhida ao outro urge com um significado único. Diálogo e Hospitalidade são expressões que se interagem e complementam. Diante do quadro atual, marcado pelo apelo da interligação, há que ampliar as malhas dessa acolhida, envolvendo não apenas os humanos, mas abrindo o leque para a dimensão mais ampla de toda a criação. O ser humano está relacionado, está vinculado na rede maior que tece o universo. Habitar a Terra ganha, assim, um significado novo, de inserção do humano no mundo da vida.</p><p> </p><p><strong>Summary:</strong></p><p>The 21st century faces one of the most singular challenges of all times. How to react to the obstacles that follow the cycle of the Anthropocene, with all its disastrous and putrid consequences? There are two possible ways: acceptance of the situation or the critical and prophetic reaction, that lies on the ground of hospitality and dialogue. When ethnocentrism, xenophobia and fundamentalism grow, dialogue and acceptance of the other urge with a special meaning. Dialogue and Hospitality are expressions that interact and complement each other. Facing the current situation, that is asking for interconnection, we must broaden the fabrics of this reception, including not only human beings, but opening the scope to a wider dimension of all creation. Humankind is related, is linked to a larger web that weaves the universe. Inhabiting the Earth gains a new meaning, to be part of life itself.</p><p><strong> Key words:</strong></p><p> Hospitality; Dialogue; Care; Spirituality; Interconnection</p>
Physical disgust, germ aversion and antifat attitudes: the mediational effect of perceived controllability of weight
Authors: Magallares Alejandro , Morales Jose Francisco 
Published: April 2017

<p>Antifat attitudes refer to stereotyping based on people’s weight. A potential explanation for the strong negative attitudes toward obese individuals relates to people’s emotional reactions. In this study, conducted with 373 female students, it is suggested that physical disgust, germ aversion and perceived controllability of weight play a central role in explaining the individual differences that exist in antifat attitudes. Our results showed a positive relationship between physical disgust and germ aversion. Additionally, it has been found a positive correlation between physical disgust and perceived controllability of weight. Furthermore, a positive relationship between antifat attitudes, physical disgust and germ aversion was found. Finally, perceived controllability of weight was positively related with antifat attitudes. The path analysis conducted showed the mediational effect of perceived controllability of weight in the relationship between physical disgust and antifat attitudes. Finally, it is discussed the results in the frame of antifat attitudes literature.</p>
Affects, resources, culture and perceived health: what is the relationship among them?
Authors: Merino Mª Dolores , Privado Jesús , Gracia Zeus 
Published: April 2017

<p>The purpose of this research is to understand if the relationship between positive and negative affect (PA/NA) and perceived health is mediated by psychosocial resources, and, whether culture (collectivistic vs. individualistic) has a role in that relationship. Structural Equation Models were applied: The first expressed the direct and indirect relationship PA/NA to health. The second reflected indirect influence of PA/NA on health and, resources mediated between both. Both models were tested in two cultures: one individualistic (Spain) and the other collectivistic (Mexico). The results showed that models work differently in both cultures. In Spain there were no significant differences between the two models. In Mexico, the direct and indirect relationship model functions better. These results have interesting implications: The influence of PA/NA on health could be different depending on the culture, so, future research to reconsider the cultural variable, would be interesting. The way PA vs. NA influences perceived health is different; PA can influence directly and indirectly, through psychosocial resources, while NA can only influence directly. It would be fascinating if future research would replicate this, including more countries, and, using biological measurements of health.</p>

<p class="Sinespaciado1"><span lang="EN-GB">Passion at work has a great influence on the occupational health of workers.<span class="hps"> Vallerand and his collaborators have defined two types of passion, </span><em>Harmonious</em> <span class="hps">and<em> </em></span><em>Obsessive</em><span class="hps">. In the first type, people feel obliged to carry out an activity but freely decide to do it and do so in harmony with other aspects of their lives. And in the second, although the person likes the activity, they feel obliged to take part in it because of internal circumstances that exercise control over them. </span>In this context, the objective was to adapt Vallerand and Houlfort’s Passion towards Work Scale (PTW) into Spanish. The participants were 513 workers, selected through non-probability sampling. We used the FACTOR program (version 7.2) and SPSS 20.0. The results of the CFA (ESEM) for the PTW scale supported the two-factor model (Harmonious Passion and Obsessive Passion), presented adequate reliability and evidence of validity with Burnout, Irritation, Engagement and Self-Efficacy. The PTW Scale and Questionnaire are reliable and valid instruments, suitable for being used in Spanish. </span></p>
Efecto del temperamento infantil en el peso del niño preescolar: una revisión sistemática
Authors: Amaro Hinojosa Marily Daniela , Flores Pena Yolanda 
Published: April 2017

Antecedentes: El temperamento es una variable que recientemente ha resultado de interés por considerarse un factor de riesgo de la obesidad infantil. Algunos estudios señalan que el temperamento difícil se asocia al incremento del peso en los preescolares. <br /><br />Objetivo: Analizar la literatura disponible sobre la asociación entre el temperamento infantil y el IMC del niño preescolar.<br /><br /> Métodos: Se realizó una revisión de la literatura sobre estudios que evaluaran la asociación entre el temperamento e índice de masa corporal en el niño preescolar, la búsqueda se realizó en los meses de mayo y junio del 2016, en bases de datos como Pubmed, EBSCO host, Ovid, Springer Link y Google académico, se incluyeron estudios que no tuvieran más de 10 años de haberse publicado y que cumplieran con los criterios de inclusión y calidad en la metodología y resultados presentados, como referencia para la evaluación de los estudios se utilizó la guía Critical Apprasisal Skills Programme Español.<br /><br />Resultados: Se encontraron 784 artículos, de los cuales solo nueve se incluyeron para esta revisión, seis de los estudios evaluaban el temperamento en base a la reactividad atencional y/o rasgos, tres evaluaban el temperamento en base a la autorregulación del niño y solo uno evaluó tanto la reactividad emocional como la autorregulación. Pareciera que la reactividad negativa y la baja autorregulación son factores asociados a la obesidad infantil en la edad preescolar. <br /><br />Conclusiones: La literatura encontrada sugiere que es necesaria mayor investigación para determinar el comportamiento del temperamento en torno a la obesidad en los niños. <br /><br />
Le long cheminement vers la bien-traitance des enfants
Authors: Brisset Claire 
Published: April 2017

De tous temps, les humains ont manifesté à l’égard des enfants une double attitude, en apparence contradictoire : le besoin de les protéger pour conserver à travers eux une bribe d’immortalité; et le besoin de s’en protéger car les enfants sont une menace puisque, comme le dit l’adage, ils nous enterront tous. Les cultures humaines ont toutes vécu avec cette double conception qui leur a inspiré des mouvements divers mais le deuxième terme de la contradiction l’a toujours emporté. Le besoin de mettre les enfants à distance, de les contrôler, même au prix de la violence, a dominé pendant des siècles jusqu’au moment où a émergé, non sans mal, l’idée que les enfants avaient des droits et que ces droits devaient être protégés par des textes, au même titre que les droits de l’homme dont ils sont issus. Mais ce chemin sera encore long.
Châtiments corporels sur les enfants : conséquences légales au Canada
Authors: Laurin Geneviève 
Published: April 2017

La revue des plus récentes études psychosociales et neurologiques révèle sans équivoque que les châtiments corporels constituent une méthode de discipline qui est non seulement inefficace et sans effet bénéfique, mais qui pose au contraire un risque important d’effets préjudiciables à court, moyen et long terme pour les enfants, notamment en raison de leurs impacts négatifs sur leur santé physique et mentale de même que sur leur développement. D’autre part, l’analyse de la jurisprudence en lien avec les châtiments corporels depuis Canadian Foundation for Children, Youth and the Law c. Canada [2004] 1 RCS 76 démontre qu’en vertu de l’article 43 du Code criminel, la protection accordée aux parents canadiens qui utilisent ces méthodes de discipline est extrêmement limitée devant les tribunaux canadiens, puisque les critères stricts établis dans cet arrêt rendent cette défense pratiquement inapplicable. Pour ces raisons, la légitimité de l’article 43 du Code criminel doit être remise en cause.
Sexe, genre et contexte : Une compréhension en matière de promotion de la santé sexuelle et prévention du VIH/ITS auprès des jeunes autochtones au Nouveau-Brunswick
Authors: Dubé Anik , Boudreau Julie Émelie 
Published: April 2017

Au Canada, les jeunes autochtones sont confrontés de plus en plus aux taux importants d’infections transmissibles sexuellement (ITS) et à une épidémie du virus de l’immunodéficience humaine (VIH). Des expériences historiques et les conditions sociales actuelles interagissent pour avoir une incidence sur la vulnérabilité de la population autochtone. Le but de cette étude ethnographique était d’améliorer la compréhension de la santé publique des jeunes autochtones et leurs expériences en matière de promotion de la santé sexuelle et de prévention de VIH/ITS. Un devis qualitatif axé sur l’approche communautaire et culturelle a servi à comprendre l’expérience des jeunes pour accéder à des services de dépistage. Vingt jeunes ont participé à l’étude. L’analyse thématique a permis d’identifier quatre thèmes : financement et législation; intergénération et santé sexuelle; contexte de santé sexuelle et éducation; perceptions des services de santé sexuelle et dépistage du VIH/ITS. Il est essentiel que les prestataires de santé et les décideurs adoptent une approche culturellement adéquate et respectueuse des genres en matière de promotion et de prévention.
