Sur l'existence de paléo-crypto karsts dans le bassin de l'Oubangui (République centrafricaine)
Authors: Boulvert Yves , Salomon Jean-Noël 
Published: April 2017

La présence de multiples indices
de formations carbonatées (signales par de nombreux naturalistes) et notamment celle de nombreuses dépressions fermées à allure de dolines, mais développées dans des formations altéritiques superficielles, laissait présumer l'existence de crypto-karsts anciens dans le bassin de l'Oubangui. La mise en évidence par sondage de la série carbonatée (200 m de puissance) dite de Bakouma, à la fin des années 1960, a confirmé l'existence d'un paléokarst très ancien. D'autres pourraient exister notamment là où en surface les dépressions fermées se multiplient. Le problème est de savoir quelle est la part qui revient à l'hydrocompaction et quelle est celle qui est fonction du soutirage karstique dans l'élaboration du modelé. Les auteurs suggèrent une voie de recherche par les analyses d'eau, car les premiers résultats obtenus sur l'Oubangui sont encourageants. Enfin, grâce au recoupement des nombreux indices, une première cartographie des formations carbonatées en Centrafrique est proposée.

Abstract
The management of wintering North American waterfowl is based on the premise that the amount of foraging habitat can limit populations. To estimate carrying capacity of winter habitats, managers use bioenergetic models to quantify energy (food) availability and energy demand, and use results as planning tools to meet regional conservation objectives. Regional models provide only coarse estimates of carrying capacity because habitat area, habitat energy values, and temporal trends in population-level demand are difficult to quantify precisely at large scales. We took advantage of detailed data previously collected on wintering waterfowl at Edwin B. Forsythe National Wildlife Refuge and surrounding marsh, New Jersey, USA, and created a well-constrained local model of carrying capacity. We used 1,223 core samples collected between 2006 and 2015 to estimate available food. We used species-specific 24-h time-activity data collected between 2011 and 2013 to estimate daily energy expenditure, morphometrically corrected for site- and day-specific thermoregulatory costs. To estimate population-level energy demand, we used standardized monthly ground-surveys (2005–2014) to create a migration curve, and proportionally scaled that to fit aerial survey data (2005–2014). Crucially, we also explicitly incorporated estimates of variance in all of these parameters and conducted a sensitivity analysis to diagnose the most important sources of variation in the model. Our results indicated that at estimated mean levels of supply (2.34 × 109 kcal) and cumulative demand (3.4 × 109 kcal), refuge resources were depleted before the end of the wintering season. However, at one standard error greater in supply and one standard error less in demand, 1.33 × 109 kcal remained on the landscape at the end of winter. Variation in model output appeared to be driven primarily by uncertainty in food abundance in high marsh habitats. This model allows for relative assessment of biases and uncertainties in carrying capacity modeling, and serves as a framework identifying critical science needs to improve local and regional waterfowl management planning.
T Cells in Celiac Disease

Published: April 2017

Abstract
Celiac disease is a human T cell–mediated autoimmune-like disorder caused by exposure to dietary gluten in genetically predisposed individuals. This review will discuss how CD4 T cell responses directed against an exogenous Ag can cause an autoreactive B cell response and participate in the licensing of intraepithelial lymphocytes to kill intestinal epithelial cells. Furthermore, this review will examine the mechanisms by which intraepithelial cytotoxic T cells mediate tissue destruction in celiac disease.
Best proximity points of contractive mappings on a metric space with a graph and applications
Authors: Sultana Asrifa , Vetrivel V. 
Published: April 2017

We establish an existence and uniqueness theorem on best proximity point for contractive mappings on a metric space endowed with a graph. As an application of this theorem, we obtain a result on the existence of unique best proximity point for uniformly locally contractive mappings. Moreover, our theorem subsumes and generalizes many recent fixed point and best proximity point results.

Extreme weather exposure identification for road networks – a comparative assessment of statistical methods
Authors: Schlögl Matthias , Laaha Gregor 
Published: April 2017

Abstract. The assessment of road infrastructure exposure to extreme weather events is of major importance for scientists and practitioners alike. In this study, we compare the different extreme value approaches and fitting methods with respect to their value for assessing the exposure of transport networks to extreme precipitation and temperature impacts. Based on an Austrian data set from 25 meteorological stations representing diverse meteorological conditions, we assess the added value of partial duration series (PDS) over the standardly used annual maxima series (AMS) in order to give recommendations for performing extreme value statistics of meteorological hazards. Results show the merits of the robust L-moment estimation, which yielded better results than maximum likelihood estimation in 62 % of all cases. At the same time, results question the general assumption of the threshold excess approach (employing PDS) being superior to the block maxima approach (employing AMS) due to information gain. For low return periods (non-extreme events) the PDS approach tends to overestimate return levels as compared to the AMS approach, whereas an opposite behavior was found for high return levels (extreme events). In extreme cases, an inappropriate threshold was shown to lead to considerable biases that may outperform the possible gain of information from including additional extreme events by far. This effect was visible from neither the square-root criterion nor standardly used graphical diagnosis (mean residual life plot) but rather from a direct comparison of AMS and PDS in combined quantile plots. We therefore recommend performing AMS and PDS approaches simultaneously in order to select the best-suited approach. This will make the analyses more robust, not only in cases where threshold selection and dependency introduces biases to the PDS approach but also in cases where the AMS contains non-extreme events that may introduce similar biases. For assessing the performance of extreme events we recommend the use of conditional performance measures that focus on rare events only in addition to standardly used unconditional indicators. The findings of the study directly address road and traffic management but can be transferred to a range of other environmental variables including meteorological and hydrological quantities.

Published: April 2017

Abstract. This paper compares and integrates different strategies to characterize the variability of end-of-winter snow depth and its relationship to topography in ice-wedge polygon tundra of Arctic Alaska. Snow depth was measured using in situ snow depth probes and estimated using ground-penetrating radar (GPR) surveys and the photogrammetric detection and ranging (phodar) technique with an unmanned aerial system (UAS). We found that GPR data provided high-precision estimates of snow depth (RMSE  =  2.9 cm), with a spatial sampling of 10 cm along transects. Phodar-based approaches provided snow depth estimates in a less laborious manner compared to GPR and probing, while yielding a high precision (RMSE  =  6.0 cm) and a fine spatial sampling (4 cm × 4 cm). We then investigated the spatial variability of snow depth and its correlation to micro- and macrotopography using the snow-free lidar digital elevation map (DEM) and the wavelet approach. We found that the end-of-winter snow depth was highly variable over short (several meter) distances, and the variability was correlated with microtopography. Microtopographic lows (i.e., troughs and centers of low-centered polygons) were filled in with snow, which resulted in a smooth and even snow surface following macrotopography. We developed and implemented a Bayesian approach to integrate the snow-free lidar DEM and multiscale measurements (probe and GPR) as well as the topographic correlation for estimating snow depth over the landscape. Our approach led to high-precision estimates of snow depth (RMSE  =  6.0 cm), at 0.5 m resolution and over the lidar domain (750 m × 700 m).

Diminutivos: Uma análise comparativa entre o português e o inglês
Authors: Rocha Rafael Martins , Vicente Helena Da Silva Guerra 
Published: April 2017

Diminutivos, sejam eles expressos pela forma sintética ou analítica, constituem um fenômeno comum às línguas do mundo. Em se tratando das formações morfológicas, porém, as propriedades dos afixos avaliativos podem variar a depender das particularidades de cada língua. Este artigo analisa comparativamente a expressão do diminutivo sintético no português e no inglês. Considera-se, portanto, que ambas as línguas dispõem de sufixos de diminutivo embora seja inquestionável a maior produtividade de construções morfológicas no português que no inglês. A investigação se concentra nos sufixos predominantemente empregados para a formação de diminutivos: -inho/-zinho e -ie/y, respectivamente. Uma das principais questões que têm motivado debates acerca do tema é a tentativa de classificação da morfologia avaliativa em relação às categorias flexionais e derivacionais. Baseando-se nos diversos estudos linguísticos sobre o fenômeno sob os mais variados enfoques produzidos na literatura, a comparação do diminutivo das duas línguas visa a levantar discussões quanto à natureza desse processo.
Economic Impacts of Renewable Energy Promotion in Germany
Authors: Böhringer Christoph , Landis Florian , Reaños Miguel Angel Tovar 
Published: April 2017

ABSTRACT Over the last decade Germany has boosted renewable energy in power production by means of massive subsidies. The flip side are very high electricity prices which raise concerns that the transition cost towards a renewable energy system will be mainly borne by poor households. In this paper, we combine computable general equilibrium and microsimulation analyses to investigate the economic impacts of Germany’s renewable energy promotion. We find that the regressive effects of renewable energy promotion could be attenuated by alternative subsidy financing mechanisms.
Emuna e pistis: a noção de fé no pensamento de Martin Buber
Authors: Von Zuben Newton Aquiles 
Published: April 2017

<p> paradigma estabelecido pela dualidade de “palavras-princípio” (<em>Grundwort</em>) Eu-Tu e Eu-Isso, a intuição axial do pensamento dialógico de Martin Buber se constitui como pedra angular de sua obra sobre religião: a dupla disposição de um homem-Eu e de Deus-Tu fundada num encontro recíproco. A fé – <em>Glauben </em>- é a resposta do homem a Deus, no encontro no qual Ele se mostra pela Palavra como Tu Eterno na revelação como mistério de Presença. Buber propõe duas maneiras opostas de crer: de um lado, a <em>Emunah</em>, como confiança pessoal ou abandono confiante de um povo, Israel, que se deixa guiar por Deus e, de outro lado, a <em>Pistis</em>, a qual, segundo o apóstolo Paulo, é a adesão individual a um conteúdo de fé, de um <em>credo</em> tido por verdadeiro. Os dois modos de crer, embora haja diversidade nos conteúdos de fé, podem ser apreendidos a partir de experiências vividas: tenho confiança em alguém e reconheço um fato como verdadeiro. Para tais experiências, não se consegue “dar razão” ou justificá-las. O objetivo desta comunicação é apresentar, de maneira sucinta, o pensamento de Martin Buber sobre essa questão que pode ilustrar o seu entendimento das relações entre o Cristianismo helenista e o Judaísmo. </p><p>Palavras-chave: <em>Emunah</em>; <em>Pistis</em>; Fé; Martin Buber.</p>

Published: April 2017

<p>Identifying which warning signs (WS) of intimate partner violence against girls (IPV) must be included in prevention programs is essential, since there is not an explicit consensus. Our first aim was identifying the most frequent WS included in the reviewed Spanish prevention guides by means of a content analysis performed independently by three judges. Our second aim was subjecting these to a sample of adolescents (n=60) to know: (1) if they identify them as abusive behaviours; (2) how frequently do they consider they have to occur to be WS, and; (3) how frequently they observe them in their peer environment. Among the 23 identified WS, controlling (n=11) and devaluating behaviours (n=6) are the most frequent in the reviewed literature and the formers´ the most observed in the adolescents’ environment (rank: 52.5% - 90%). The majority labelled the 23 behaviours as abusive. Four controlling and 3 devaluating behaviours had to occur <em>very often </em>to be an IPV warning sign. Therefore their tolerance to these WS is high. The outcomes are valuable for the development of prevention programs and suggest the need of investigating on the explanatory factors of such tolerance.</p>

Published: April 2017

Educación para la salud se considera un medio muy importante para ampliar los conocimientos y prácticas relacionadas con conductas saludables de los individuos. Así, el estudio tiene como objetivo caracterizar las producciones científicas y describir el trabajo de las enfermeras en las prácticas de educación en salud en la escuela. Es una revisión integradora de la literatura en las bases LILACS y BDENF. A través de los criterios de inclusión se seleccionaron 20 artículos que respondieron a la pregunta: ¿cómo la enfermera actúa en las prácticas de educación para la salud en el contexto escolar? Los resultados emergieron tres categorías para el análisis: "Educación para la salud y la cuestión de la salud pública en la escuela", "Enfermería y educación para la salud en la escuela" y "Medidas adoptadas en el ámbito escolar." A partir de 2010 se produjo un aumento significativo de publicaciones, estudios predominantemente con un enfoque cualitativo. Con todo, se percibe la complejidad de las prácticas de educación para la salud en el entorno escolar y la debilidad existente en publicaciones científicas sobre la inclusión de las enfermeras en la escuela.
