Intervenir en EPS pour développer l’entretien de soi. Une étude de cas d’un enseignant expérimenté qui débute
Authors: Loizon Denis
Published: December 2015

À partir d’une étude de cas portant sur un professeur d’éducation physique et sportive, notre recherche tente de montrer le poids des déterminants personnels (le « déjà-là ») qui agissent dans l’activité didactique du sujet en situation d’enseignement de musculation et de step. En utilisant le cadre théorique et méthodologique de la didactique clinique, nous mettons en évidence le poids du « déjà-là expérientiel » qui est déterminant dans l’engagement de cette enseignante. Ses différentes expériences en course d’orientation, constitutives de son expérience personnelle et professionnelle, structurent grandement ses conceptions de l’EPS organisée autour de quelques mots-clés : engagement physique, plaisir et compétition. L’enseignement des activités centrées sur l’entretien de soi lui fait revivre une position d’enseignante débutante alors qu’elle est déjà expérimentée. Elle s’organise alors au plan didactique pour conserver son statut de sujet supposé savoir, tout en étant très divisée entre deux intentions : développer la motricité et permettre à l’élève d’acquérir des connaissances sur lui dans ces deux activités.
Les compétences sociales à l’école primaire : essai de mesure et effets sur la réussite
Authors: Morlaix Sophie
Published: December 2015

Ce projet de recherche vise à proposer une mesure et une définition a posteriori de compétences dites sociales à l’école primaire, et à montrer l’intérêt de la prise en compte de ces compétences transversales aux apprentissages dans l’explication des différences de réussite entre élèves. Il repose sur une approche pluri-disciplinaire, permettant d’affiner les outils aussi bien conceptuels que méthodologiques servant à définir et à opérationnaliser les compétences sociales. En ce sens il mobilise des concepts ou des méthodologies empruntés à des disciplines variées (économie, sociologie, psychologie), mais dont la préoccupation commune repose sur une meilleure compréhension de la variabilité des acquisitions scolaires. Ce projet se décomposera en plusieurs points : il permettra dans un premier temps d’établir une typologie de ces compétences sociales, il proposera par la suite une mesure empirique de ces différents types de compétences sociales par des modèles économétriques appropriés, et s’attachera dans une dernière étape à mesurer leur impact sur la réussite scolaire en fin d’école primaire
La justice pénale internationale a 70 ans : entre âge de fer et âge d’or
Authors: Hubrecht Joël
Published: December 2015

Nuremberg crée le principe moderne de justice pénale internationale, dans un contexte très spécifique. Les années 1990 sont celles d’une renaissance, en particulier avec l’ex-Yougoslavie et le Rwanda. C’est la convention de Rome qui constitue une percée majeure, en créant une Cour permanente. Celle-ci est critiquée, et son statut n’est pas ratifié par la majorité des membres du Conseil de sécurité. Mais à 70 ans, l’idée de justice pénale internationale est jeune, et toujours une espérance.
Le droit à réparation devant la CPI : promesses et incertitudes
Authors: Guillaumé Jules
Published: December 2015

L’avènement de la Cour pénale internationale a permis la pleine reconnaissance de la place de la victime dans le procès international, avec l’affirmation d’un droit à réparation pour le crime de génocide, les crimes contre l’humanité et les crimes de guerre. À l’heure des premières condamnations prononcées par la Cour, la question demeure toutefois entière de savoir non pas seulement s’il est possible de réparer l’irréparable, mais comment tenter de le faire.
Présidentielles américaines : ce que nous disent les primaires
Authors: Nardon Laurence
Published: December 2015

Bien que critiquées, les primaires américaines sont importantes. Côté républicain, la multiplicité des candidatures traduit d’abord le rejet de l’ establishment , en dépit d’un certain affaiblissement des Tea Parties . Côté démocrate, la candidature de Hillary Clinton semble aujourd’hui renforcée. L’opinion américaine apparaît très divisée, entre une partie rurale, blanche et conservatrice, et une population urbaine et côtière, plus progressiste.

Securing protein for the approximate 10 billion humans expected to inhabit our planet by 2050 is a major priority for the global community. Evidence has accrued over the past 30 years that strongly supports and justifies the sustainable use of insects as a means to produce protein products as feed for pets, livestock, poultry, and aquacultured species. Researchers and entrepreneurs affiliated with universities and industries, respectively, from 18 nations distributed across North and South America, Europe, Asia, Africa and Australia contributed to the development of this article, which is an indication of the global interest on this topic. A brief overview of insects as feed for the aquaculture industry along with a review of the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae), as a model for such systems is provided.
Liaisons entre art et science : les spécificités de l’art biotechnologique
Authors: Prunet Camille
Published: December 2015

Art et science s’enrichissent mutuellement depuis de nombreux siècles, cependant le 20ème siècle a particulièrement séparé ces champs disciplinaires en privilégiant la spécialisation. Pourtant, au cours des années 1960, certains projets à finalité artistique ont commencé à associer artistes et scientifiques en s’inspirant largement des avancées scientifiques de leur époque. En se penchant plus spécifiquement sur les œuvres empruntant aux biotechnologies, leur production apparaît complexe car elles sont fragiles, souvent instables ou mortelles, et nécessitent des précautions lors de l’exposition. Par ailleurs, elles demandent des connaissances poussées et un équipement de pointe. A travers les œuvres de Jun Takita, Art Orienté objet, et Eduardo Kac, il s’agit de se pencher sur cette spécificité qu’est le recours à un élément vivant comme médium. L’utilisation du concept de médium permettra de souligner à quel point le recours aux biotechnologies dépasse la simple question logistique du support. En effet, le médium sert un objectif hybride entre matérialité et concept permettant notamment d’interroger l’épistémologie de l'histoire de l’art et de la science, et semble pertinent à souligner lors de l’exposition.
La devoción del salvaje. Religiosidad zapatista y silencio gráfico
Authors: Arnal Ariel
Published: December 2015

Durante el periodo oficial de la Revolución mexicana, 1910 a 1919, el movimiento armado encabezado por Emiliano Zapata fue constantemente objeto de tema gráfico en la prensa de la Ciudad de México. Salvo en el corto periodo del gobierno Convencionista en la ciudad capital (1915), por lo general la fotografía sobre el zapatismo fue repetidamente utilizada para denostar al Ejército del sur, en oposición a los valores tradicionales de nacionalismo, religión y familia. Sin embargo, durante el periodo descrito, existe un tema que nunca aparece publicado, la utilización de símbolos religiosos por parte de los surianos. En contraste, en archivo encontramos infinidad de fotografías que documentan el profundo sentimiento religioso del ejército zapatista y de sus caudillos. En este sentido, tanto la utilización de dichos símbolos por los alzados como la omisión en la prensa capitalina de esta valiosa información gráfica, nos hablan de la construcción de un discurso editorial sustentado paradójicamente en el silencio, silencio que se constituye en un verdadero actor dramático profundamente elocuente.
Arte y fotografía en la prensa mexicana. La primera exposición de arte de los fotógrafos de prensa en 1911
Authors: Escorza Rodríguez Daniel
Published: December 2015

El propósito de este trabajo es explorar la condición estética de la fotografía producida por los fotógrafos de la prensa en esa primera década del siglo XX. Específicamente vamos a revisar cómo se organizó y desarrolló la primera Exposición de Arte Fotográfico, auspiciada por la Sociedad de Fotógrafos de la prensa Metropolitana e inaugurada en la ciudad de México el 8 de diciembre de 1911. Más allá de la descripción del evento y de la posible identificación de las imágenes que ahí se presentaron, el interés de este trabajo se orienta al análisis de la noción de arte y de fotografía entre los fotógrafos que expusieron por primera vez en esa ocasión, como Agustín Casasola, Manuel Ramos, Gerónimo Hernández, Ezequiel Álvarez Tostado, Antonio Garduño y Samuel Tinoco, entre otros fotógrafos mexicanos de los inicios del siglo XX.
Em foco a galeria dos condenados da casa de correção: diferentes modos de ver
Authors: Nogueira da Silva Marilene Rosa
Published: December 2015

Numa das oficinas da Casa de Correção do Rio de Janeiro, criada em 1850, um dos apenados transforma prisioneiros em modelos peculiares. Os retratos que marcaram a utilização pioneira no Brasil da fotografia como instrumento de identificação criminal, compõem os álbuns da Coleção Dona Theresa Christina- Sessão de Manuscritos da Biblioteca Nacional. O experimento fotográfico, coordenado pelo médico Luis Vianna de Almeida Valle, diretor da prisão, emerge articulado a um projeto de classificação antropológica das fichas médico psicológicas com informações sobre a personalidade e hereditariedade dos prisioneiros. Ilumino do conjunto escravos prisioneiros identificados por suas procedências. De imagem de prisioneiros à mostra tecnológica, exibida na Exposição Internacional de 1876 na Filadélfia, constitui-se na atualidade em arquivo histórico e, como tal, materialidade de uma pesquisa que estuda a prisão como lugar da punição na cidade do Rio de Janeiro.
Los quehaceres de los fotohistoriadores mexicanos:¿eurocentristas, americanistas o nacionalistas?
Authors: Monroy Nasr Rebeca
Published: December 2015

Bajo este título me propongo revisar de manera puntual algunos textos de los historiadores de la fotografía mexicana, de aquellos que han venido trabajando la historia gráfica desde los últimos años del siglo XX y principios del XXI, con la idea de poder analizar la manera en que se está historiando la fotografía en México. La propuesta se basa en la posible comparación de los trabajos primigenios con los iniciáticos, sus cambios, propuestas, diferencias y semejanzas entre los años ochenta y los primeros diez de la presente centuria. En un ejercicio analítico desde su metodología, conceptualización, desarrollos, apropiaciones y propuestas particulares, de tal modo que con algunos textos paradigmáticos sea posible encontrar si los historiadores mexicanos han avanzado en completar, falsificar, imitar o proponer elementos a la mesa del análisis histórico con imágenes. La cultura visual, la historia social y la historia cultural como marcos referenciales de análisis, pero también el marco de la estética y lo documental de la fotografía entrarán en juego en el análisis de la lectura de los textos historiográficos mexicanos.

Published: December 2015

El proyecto de análisis es identificar acciones para la transmisión de imágenes fotográficas del siglo XIX y XX. La propuesta central indica que las fotografías definen un punto de modernidad cultural impregnado, afectando a la representación personal y el paso de lo privado a lo público. Este camino implica aspectos morales, culturales y mediáticos para resituar el papel de la fotografía en un país como Chile.
Analogías: Fotografía y literatura en Mario Bellatin
Authors: de los Ríos Valeria
Published: December 2015

Este artículo es una aproximación a dos textos de Mario Bellatin que incluyen fotografías: Las dos Fridas y Los fantasmas del masajista. Bellatin se inscribe en una tradición que incluye en Latinoamérica la fotografía tanto retórica como materialmente. Su innovación consiste en alejarse de los modelos tradicionales de la fotografía como documento o registro (las nociones de referencialidad e indexicalidad del discurso fotográfico), instalándose en una visión más analógica de la fotografía que apunta a las relaciones entre sujetos y circunstancias a veces impensadas.
Curiosas páginas negras

Published: December 2015

Este ensayo aborda dos posibles antecedentes de las páginas negras incluidas en Tristram Shandy del autor inglés Lawrence Sterne (1713-1768). Una de las fuentes serían las páginas de duelo del siglo anterior, algunas de ellas con textos blancos sobre fondo negro, o completamente negras. Otra de las fuentes sería el libro Utris Cosmi, Maioris scilicet et Minoris Metaphysica, Physica atque Technica Historia, un tratado sobre el macro y microcosmos de Robert Fludd.

Development of synovial membrane in the temporomandibular joint of the human fetus
Authors: Carvalho de Moraes L.O. , Tedesco R.C. , Arraez-Aybar L.A. , Klein O. , MÃ©rida-Velasco J.R. , Alonso L.G.
Published: December 2015

The development of the synovial membrane was analyzed in serial sections of 21 temporomandibular joints of human fetuses at 9 to 13 weeks of gestation. Sections of two fetuses at 12 weeks of development were used to perform immunohistochemical expression of the markers CD68 and Hsp27 on the synovial lining. Macrophage-like type A and fibroblast-like type B cells, which express CD68 and Hsp27, respectively, were observed at the twelfth week of development. Our results suggest that the development of the synovial membrane is related to the vascularization of the joint and the formation of the articular cavities.
Specific Echocardiographic Findings Useful for the Diagnosis of Common Pulmonary Vein Atresia
Authors: Nagasawa Hiroyuki , Hirata Kazuhiro
Published: December 2015

In this paper, we report a case of common pulmonary vein atresia, which is a very rare disease characterized by cyanosis, heart failure and pulmonary hypertension. Reverse flow in the pulmonary artery at end-diastole as well as in the isthmus of the aorta from early systole to end-diastole detected by echocardiography were found to be specific features useful in diagnosing the disease.
Confirmed organophosphorus and carbamate pesticide poisonings in South African wildlife (2009–2014)
Authors: Botha Christo J. , Coetser Heleen , Labuschagne Leonie , Basson Andre
Published: December 2015

During a six-year period (from January 2009 to December 2014), specimens collected from 344 cases of suspected organophosphorus and carbamate pesticide poisonings in wildlife, including birds, were submitted to the Toxicology Laboratory (ARC-OVI) for analysis. A positive diagnosis was made in 135 (39%) of these cases. The majority of cases were from birds, which included Cape vultures (Gyps coprotheres) and African white-backed vultures (Gyps africanus) and bateleur eagles (Terathopius ecaudatus). In one incident 49 vultures were killed when a farmer intentionally laced carcasses with carbofuran in an attempt to control jackal predation. There were 22 incidents of poisoning in helmeted guineafowl (Numida meleagris). On nine different occasions blue cranes (Anthropoides paradiseus) were poisoned, in one incident 14 birds were reported to have been killed. Over the period of investigation, there were 20 cases of poisoning involving mammalian species, the majority being vervet monkeys (Chlorocebus pygerythrus). The carbamate pesticides were responsible for 57 incidents of poisoning. Aldicarb, carbofuran and methomyl were detected in 26, 18 and 12 cases respectively. The majority of organophosphorus pesticide poisonings were caused by diazinon (n = 19), monocrotophos (n = 13) and methamidophos (n = 10).
DDA: A Novel Network-Based Scoring Method to Identify Disease-Disease Associations
Authors: Suratanee Apichat , Plaimas Kitiporn
Published: December 2015

Categorizing human diseases provides higher efficiency and accuracy for disease diagnosis, prognosis, and treatment. Disease-disease association (DDA) is a precious information that indicates the large-scale structure of complex relationships of diseases. However, the number of known and reliable associations is very small. Therefore, identification of DDAs is a challenging task in systems biology and medicine. Here, we developed a novel network-based scoring algorithm called DDA to identify the relationships between diseases in a large-scale study. Our method is developed based on a random walk prioritization in a protein-protein interaction network. This approach considers not only whether two diseases directly share associated genes but also the statistical relationships between two different diseases using known disease-related genes. Predicted associations were validated by known DDAs from a database and literature supports. The method yielded a good performance with an area under the curve of 71% and outperformed other standard association indices. Furthermore, novel DDAs and relationships among diseases from the clusters analysis were reported. This method is efficient to identify disease-disease relationships on an interaction network and can also be generalized to other association studies to further enhance knowledge in medical studies.

Published: December 2015

We report a case of squamous cell lung cancer with transbronchial dissemination in a 73-year-old man. Bronchoscopic examination revealed multiple bronchial mucosal nodules that existed independently of one another. We reviewed 16 previous cases of endobronchial metastasis in lung cancer. All patients were men. Among the reports that described the smoking history, most patients were smokers (6/7), and the most frequent histological type of cancer was squamous cell carcinoma (11/17). Although hematogenous and lymphogenous routes have been reported as metastatic mechanisms, no previous cases involving transbronchial dissemination have been described. Transbronchial dissemination may be an alternative pathway of endobronchial metastasis.
Desmodium adscendens . De l’usage traditionnel camerounais contre les hépatites à l’accompagnement des chimiothérapies

Published: December 2015

Desmodium adscendens (Da) est une espèce pantropicale qui jouit d’une réputation de plante médicinale pratiquement dans tous les pays où elle croît. C’est en 1965 que le Dr P. Tubéry, alors médecin coopérant au nord Cameroun recueillit de la bouche d’un tradipraticien des informations concernant son usage contre les hépatites et son mode de préparation. Convaincu de l’efficacité de cette espèce et de son intérêt en thérapeutique, le Dr P. Tubéry l’introduisit en France et, avec la collaboration de Mme J. Ragot, pharmacienne, mena des travaux afin de mieux cerner ses indications thérapeutiques, sa pharmacologie et sa composition chimique, ce qui conduisit à la production d’une formulation galénique reproduisant l’efficacité thérapeutique de la préparation traditionnelle. La réputation de Da s’étendit progressivement jusqu’à connaître un grand succès, et actuellement en Europe, cette espèce est devenue une référence incontournable à l’instar du Chardon Marie (Silybum marianum L. Gaertn.), en particulier pour toutes ses applications dans les pathologies du foie (atteintes chroniques ou aiguës, en tant qu’agent curatif et/ou préventif), mais aussi pour d’autres indications. Le but cet article est de faire le point sur les travaux réalisés sur cette espèce, dans un but de validation et de recommandations d’usage.
Limited effect of anthropogenic nitrogen oxides on secondary organic aerosol formation

Published: December 2015

Abstract. Globally, secondary organic aerosol (SOA) is mostly formed from emissions of biogenic volatile organic compounds (VOCs) by vegetation, but it can be modified by human activities as demonstrated in recent research. Specifically, nitrogen oxides (NOx = NO + NO2) have been shown to play a critical role in the chemical formation of low volatility compounds. We have updated the SOA scheme in the global NCAR (National Center for Atmospheric Research) Community Atmospheric Model version 4 with chemistry (CAM4-chem) by implementing a 4-product volatility basis set (VBS) scheme, including NOx-dependent SOA yields and aging parameterizations. Small differences are found for the no-aging VBS and 2-product schemes; large increases in SOA production and the SOA-to-OA ratio are found for the aging scheme. The predicted organic aerosol amounts capture both the magnitude and distribution of US surface annual mean measurements from the Interagency Monitoring of Protected Visual Environments (IMPROVE) network by 50 %, and the simulated vertical profiles are within a factor of 2 compared to aerosol mass spectrometer (AMS) measurements from 13 aircraft-based field campaigns across different regions and seasons. We then perform sensitivity experiments to examine how the SOA loading responds to a 50 % reduction in anthropogenic nitric oxide (NO) emissions in different regions. We find limited SOA reductions of 0.9–5.6, 6.4–12.0 and 0.9–2.8 % for global, southeast US and Amazon NOx perturbations, respectively. The fact that SOA formation is almost unaffected by changes in NOx can be largely attributed to a limited shift in chemical regime, to buffering in chemical pathways (low- and high-NOx pathways, O3 versus NO3-initiated oxidation) and to offsetting tendencies in the biogenic versus anthropogenic SOA responses.
Spatial and temporal variations of the concentrations of PM10, PM2.5 and PM1 in China
Authors: Wang Y. Q. , Zhang X. Y. , Sun J. Y. , Zhang X. C. , Che H. Z. , Li Y.
Published: December 2015

Abstract. Concentrations of PM10, PM2.5 and PM1 were monitored at 24 CAWNET (China Atmosphere Watch Network) stations from 2006 to 2014. The highest particulate matter (PM) concentrations were observed at the stations of Xian, Zhengzhou and Gucheng, on the Guanzhong Plain and the Huabei Plain (HBP). The second highest PM concentrations were observed in northeast China, followed by southern China. According to the latest air quality standards of China, 14 stations reached the PM10 standard, and only 7 stations, mainly rural and remote stations, reached the PM2.5 standard. The ratios of PM2.5 to PM10 showed a clear increasing trend from northern to southern China, because of the substantial contribution of coarse mineral aerosol in northern China. The ratios of PM1 to PM2.5 were higher than 80 % at most stations. PM concentrations tended to be highest in winter and lowest in summer at most stations, and mineral dust influenced the results in spring. A decreasing interannual trend was observed on the HBP and in southern China for the period 2006 to 2014, but an increasing trend occurred at some stations in northeast China. Bimodal and unimodal diurnal variation patterns were identified at urban stations. Both emissions and meteorological variations dominate the long-term PM concentration trend, while meteorological factors play a leading role in the short term.
Viscous organic aerosol particles in the upper troposphere: diffusivity-controlled water uptake and ice nucleation?

Abstract. New measurements of water diffusion in secondary organic aerosol (SOA) material produced by oxidation of α-pinene and in a number of organic/inorganic model mixtures (3-methylbutane-1,2,3-tricarboxylic acid (3-MBTCA), levoglucosan, levoglucosan/NH4HSO4, raffinose) are presented. These indicate that water diffusion coefficients are determined by several properties of the aerosol substance and cannot be inferred from the glass transition temperature or bouncing properties. Our results suggest that water diffusion in SOA particles is faster than often assumed and imposes no significant kinetic limitation on water uptake and release at temperatures above 220 K. The fast diffusion of water suggests that heterogeneous ice nucleation on a glassy core is very unlikely in these systems. At temperatures below 220 K, model simulations of SOA particles suggest that heterogeneous ice nucleation may occur in the immersion mode on glassy cores which remain embedded in a liquid shell when experiencing fast updraft velocities. The particles absorb significant quantities of water during these updrafts which plasticize their outer layers such that these layers equilibrate readily with the gas phase humidity before the homogeneous ice nucleation threshold is reached. Glass formation is thus unlikely to restrict homogeneous ice nucleation. Only under most extreme conditions near the very high tropical tropopause may the homogeneous ice nucleation rate coefficient be reduced as a consequence of slow condensed-phase water diffusion. Since the differences between the behavior limited or non limited by diffusion are small even at the very high tropical tropopause, condensed-phase water diffusivity is unlikely to have significant consequences on the direct climatic effects of SOA particles under tropospheric conditions.
Development of coccolithophore-based transfer functions in the western Mediterranean sea: a sea surface salinity reconstruction for the last 15.5 kyr
Authors: Ausín B. , Hernández-Almeida I. , Flores J.-A. , Sierro F.-J. , Grosjean M. , Francés G. , Alonso B.
Published: December 2015

Abstract. A new data set of 88 marine surface sediment samples and related oceanic environmental variables (temperature, salinity, chlorophyll a, oxygen, etc.) was studied to quantify the relationship between assemblages of coccolithophore species and modern environmental conditions in the western Mediterranean Sea and the Atlantic Ocean, west of the Strait of Gibraltar. Multivariate statistical analyses revealed that coccolithophore species were primarily related to sea surface salinity (SSS), explaining an independent and significant proportion of variance in the coccolithophore data. A quantitative coccolithophore-based transfer function to estimate SSS was developed using the modern analog technique (MAT) and weighted-averaging partial least square regression (WA-PLS). The bootstrapped regression coefficient (R2boot) was 0.85MAT and 0.80WA-PLS, with a root-mean-square error of prediction (RMSEP) of 0.29MAT and 0.30WA-PLS (psu). The resulting transfer function was applied to fossil coccolithophore assemblages in the highly resolved (~ 65 years) sediment core CEUTA10PC08 from the Alboran Sea (western Mediterranean) in order to reconstruct SSS for the last 25 kyr. The reliability of the reconstruction was evaluated by assessing the degree of similarity between fossil and modern coccolithophore assemblages and by a comparison of reconstructions with fossil ordination scores. Analogs were poor for the stadials associated with Heinrich events 2 and 1 and part of the Last Glacial Maximum. Good analogs indicate a more reliable reconstruction of the SSS for the last 15.5 kyr. During this period, several millennial and centennial SSS changes were observed and associated with sea-level oscillations and variations in the Atlantic Water entering the Alboran.
On the inclusion of GPS precipitable water vapour in the nowcasting of rainfall
Authors: Benevides P. , Catalao J. , Miranda P. M. A.
Published: December 2015

Abstract. The temporal behaviour of precipitable water vapour (PWV) retrieved from GPS delay data is analysed in a number of case studies of intense precipitation in the Lisbon area, in the period 2010–2012 and in a continuous annual cycle of 2012 observations. Such behaviour is found to correlate positively with the probability of precipitation, especially in cases of severe rainfall. The evolution of the GPS PWV in a few stations is analysed by a least-squares fitting of a broken line tendency, made by a temporal sequence of ascents and descents over the data. It is found that most severe rainfall events occur in descending trends after a long ascending period and that the most intense events occur after steep ascents in PWV. A simple algorithm, forecasting rain in the 6 h after a steep ascent of the GPS PWV in a single station, is found to produce reasonable forecasts of the occurrence of precipitation in the nearby region, without significant misses in what concerns larger rain events, but with a substantial amount of false alarms. It is suggested that this method could be improved by the analysis of 2-D or 3-D time-varying GPS PWV fields or by its joint use with other meteorological data relevant to nowcast precipitation.
The Andalusi Turn: The Nūba in Mediterranean History
Authors: Davila Carl
Published: December 2015

Variations among the contemporary North African nūba poetic-musical traditions, as well as their shifting social bases, show that migration to and elaboration within North African societies transformed the elite musical artistry of al-Andalus. Viewing the Andalusian nūba as a trans-Mediterranean phenomenon illustrates the significant diversity that lay beneath the apparent uniformity of erudite Arab-Mediterranean culture in the late medieval and early modern periods.
Legitimación cognitiva de políticas de calidad universitaria a través del proceso de aprendizaje y rendimiento académico
Authors: Rodríguez A. Sandra E.
Published: December 2015

Existe una variedad de comportamientos estudiantiles relativos al aprendizaje, más no todos conducen a un rendimiento académico avanzado. Sin embargo, las instituciones declaran en su política, estándares de calidad a cumplir por los actores que intervienen en el hecho educativo. El problema está en la construcción de esa política y cómo se disemina y arraiga en la cognición de éstos, de manera que los procesos continuos para el aprendizaje y los resultados de éstos, sean congruentes con las expectativas declaradas por la institución, ya que su visión es posicionarse frente a sus públicos, con una imagen de calidad. Para tener una ilustración se analizó la teoría de los constructos personales de Kelly (1969), para exponer la hipótesis: que con los años los niños y jóvenes encallan acciones relacionadas con hábitos de estudio, pero en la mayoría de los casos, no conducen a la excelencia. Se planteó como objetivo de la investigación-acción: explicar los procesos de aprendizaje que emplean los universitarios y en consecuencia su rendimiento académico y a partir de los resultados, intervenir en pro de la mejora de los procesos de aprendizaje.Paradigma - Revista de Investigación Educativa.

Factores sociodemográficos relacionados con el acceso a la justicia de la mujer víctima de violencia doméstica en Honduras, año 2012
Authors: Chávez Baca Raúl Iván
Published: December 2015

La violencia contra las mujeres genera la principal demanda de acceso a la justicia para el Poder Judicial, debido a que el 57.9% de la población de mujeres vive en pareja, ya sea casada o en unión libre y por la cultura patriarcal imperante. Sin embargo, es un tema con poca trascendencia para el Poder Judicial, institución que le da mayor énfasis al acceso a la justicia a otros problemas sociales que al ser comparados con la problemática de violencia contra las mujeres son de inferior demanda de acceso. A partir de indicadores estadísticos se percibe una desigualdad en el acceso a la justicia en menoscabo de las mujeres de zonas rurales, ya que las que habitan las zonas urbanas gozan de un mejor servicio. La reducción de la fecundidad dentro de 15 años así como la transición demográfica y el aumento del nivel educativo de las mujeres indirectamente serán factores de aumento de la demanda de las mujeres de acceso a la justicia ya que estos factores generarán una mayor participación social y económica de las mujeres.Revista Población y Desarrollo: Argonautas y Caminantes, Vol. 11, 2015: 9-20
On Guidelines for College English Teaching and Challenges for College English Teachers
Authors: Li Huiyin
Published: December 2015

This article performs an exploratory study of the newly formulated Guidelines for College English Teaching (Draft Exposure)(2015)(Guidelines), aiming at exploring how different the latest Guidelines is from the previous ones, what challenges it brings to teachers and how these challenges can be countered. Therefore, comparisons are made among six syllabi to illustrate the developments college English has achieved and its existent problems as well. To address these problems, Guidelines (2015) is issued with three new features: the integration of instrumentality and humanity, the introduction of intercultural education and the system of multiple curriculum for multiple teaching objectives. Its issuing poses tremendous challenges to college English teachers, of which increasing demands on college English teachers' professional expertise, skillful employment of information technology and academic performance stand out. To help counter these challenges and difficulties, suggestions are made from three levels with the hope that improved teachers' quality can facilitate the implementation of Guidelines (2015) and guarantee the potential achievement of its expected objectives. These suggestions are: life-long learning and self-directed development consciousness, the establishment of teacher education system by faculties and universities and continued governmental support in and favorable policies to college English teacher education.

The effect of African yam bean (Sphenostylis stenocarpa) on serum calcium, inorganic phosphate, alkaline phosphatase and uric acid concentration was investigated. Eighteen male Wister albino rats were used for the experiment. The rats were divided into three groups of six rats each viz: the Baseline, Test and Control. The test group was fed with a diet prepared with 16% African yam bean, 50% maize flour, 23% groundnut cake and 10% fishmeal. The Control group received a diet without Africa yam bean but containing other components. The Baseline group was sacrificed at the onset of the study to ascertain the initial conditions. The study lasted for twenty eight days after which the serum calcium, inorganic phosphate, alkaline phosphatase and uric acid levels were estimated. The inorganic phosphate and alkaline phosphatase of the test group showed a significant (p < 0.05) increase with the values; 25.154 ± 4.329 and 506.00 ± 51.594 respectively compared to those of the Baseline and Control groups. Also there were significant (p < 0.05) reductions of the serum concentration of calcium and uric acid of the test group compared to those of the Baseline and Control groups. There were no significant (p > 0.05) differences in the serum levels of calcium, alkaline phosphatase, inorganic phosphate and uric acid of the Baseline and Control groups. These observed effects of African yam bean has gone a long way to provide an insight into the pharmacological potentials of this legume especially in the management of gout and arthritis in addition to the already known nutritional properties.

The major objective of this research paper is to synthesis sulfur nanoparticles (SNPs) by green route, which can improve plant’s growth and reduce the environmental pathogens. Sulfur nanoparticles (SNPs) were synthesized by a simple green procedure using Melia azedarach leaves aqueous extract and citric acid. The leaves of Melia azedarach aqueous extract act as a capping and stabilizing agent in the formation of sulfur nanoparticles. The synthesized sulfur nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The average particles diameter size was found to be 20 ± 4 nm. Analysis showed that the nanoparticles are crystalline in nature, with spherical shape. A preliminary field study was conducted to evaluate growth and development of Cucurbita pepo in response to sulfur nanoparticles.
Estimation of the bus delay at the stopping point on the base of traffic parameters

Published: December 2015

Contemporary methods of spatial planning of urban transport systems provide for designers enough opportunities in selecting the placement of stopping points for public transport. However in every city there exist very intense sections of the road network with a small width of the roadway. In these sections there is no opportunity to allocate special lanes for public transport. If the stop pockets on such street exist, there appear traffic conflicts when buses depart from the stopping point. Authors propose theoretical model for estimation of the bus delay at the stopping point on the base of traffic parameters. Use of the proposed model allows reducing amount of field surveys while grounding the decisions about rational variant of allocation of the bus stopping points. The paper describes some experimental results obtained with the use of the proposed model while field surveys at the most loaded streets in the central part of Kharkiv (Ukraine).

Published: December 2015

The article concerns on a methodological approach to design Rest and Service Areas. Because there is recorded steady growth in food cargo that require specific temperatures its resulting in an increase in demand for specialized transport. Transportation of food is usually done using vehicles equipped with refrigeration or heating. The article presents the design requirements for Rest and Service Areas (RSA), which is one of the most important elements of the road network, that condition affects the safety of drivers and cargo. Based on growth assumptions of effectiveness a functional model of RSA consisting five data bases and nine research tasks has been proposed. As a primary parameter studied in the model was the RSA effectiveness assessed by the rate of parking spaces utilization. The values of this index were estimated according to the share of traffic cars leave the motorway to the traffic flow of cars on the motorway. Evaluation of test results was based on the indicative comparative analysis of the existing and forecasted traffic flows of trucks with loads sensitive to the conditions and the time of their carriage. In the article pointed out that decisions taken in the course of modernization of the national RSA network should be reviewed and assessed through simulation studies of the transport process taking into account different boundary conditions, a risk analysis of transport depending on the type of transported cargo and analyze the efficiency and profitability of the national network creation of parking places adapted to specialized service of trucks carrying food cargo.

Published: December 2015

To increase the efficiency of transport nodes functioning taking into account the logistics management principles it is necessary to optimize the structure and capacity of transport nodes' production resources, and to develop such a method for calculating of joint schedules for vehicles and freight hubs of the transport node, which takes into account stochastic nature of the parameters of material and informational flows. For solving the problems of optimal management of transport nodes functioning processes it is proposed to use the specific efficiency indicator, which is determined as a ratio of total costs of clients servicing in transport node to the costs of production resources used while servicing. According to the used approach for formalization of the transport node internal processes, development of the simulation model was implemented on the base of object-oriented programming principles. TransportNode.dll class library has been used as basic tool for simulations. The model implemented on the base of the library allows to take into account stochastic nature of demand and probabilistic nature of technological processes in transport nodes. Some results of numeric simulations for the loading area “Amur-Gavan” of Dnipropetrovsk River Port have been described in the paper.

Repensando las narrativas nacionales: Un análisis del origen, transmisión e influencia en el aprendizaje histórico
Authors: López Rodriguez César
Published: December 2015

El formato narrativo ocupa un papel central en el ámbito de la historia, tanto en la generación del conocimiento histórico como en su transmisión y aprendizaje. Sin duda, una de las narrativas más frecuentes y dominantes en el campo son las denominadas narrativas nacionales. Estas narrativas, frecuentemente basadas en mitos y leyendas, buscan principalmente celebrar el pasado nacional, dificultando en gran medida una comprensión crítica del mismo. El presente artículo pretende contribuir a comprender el papel que juegan estas narrativas nacionales en la producción y el consumo del conocimiento histórico a través de un análisis en diferentes ámbitos: el académico, el escolar y el ámbito informal. Finalmente, se presenta una reflexión sobre algunos de los estudios empíricos más recientes que analizan la influencia de estas narrativas nacionales en el aprendizaje de los estudiantes.

The narrative format plays a central role in the field of history, both in the production of historical knowledge and its transmission and also when it comes to learning. One of the most common and dominant narratives are the so-called national narratives. These narratives, frequently based on myths and legends, aim to celebrate the nation and hinder a critical understanding of the past. This article seeks a better understanding of the role that these national narratives play in the production and consumption of historical knowledge through an analysis in different contexts: academic, school and at an informal ambit. Finally, some of the most recent empirical studies on the influence of these national narratives on students learning are discussed.
Heart Transplant Recipient with History of Chagas Disease and Elevated Panel-Reactive Antibodies
Authors: Davalos-Krebs Gleidys
Published: December 2015

Chagas disease is caused by a protozoan named Trypanosoma cruzi transmitted to humans by reduviid bugs. Severe dilated cardiomyopathy from chronic T cruzi infection is the most common finding, leading to end-stage heart failure. Heart transplant is an effective treatment for Chagas heart disease. However, T cruzi reactivation is of great concern, predisposing patients to episodes of myocarditis and rejection. A 56-year-old woman with a history of Chagas disease and elevated calculated panel reactive antibodies (CPRAs) underwent induction therapy and desensitization strategies aimed at lowering CPRAs, as elevated CPRAs have been implicated in the development of antibody-mediated rejection and reduced allograft survival. Clinical phases and signs and symptoms of Chagas disease are briefly described in an attempt to promote awareness of the disease among clinicians. In addition, serology assays approved in the United States as well as recommendations of experts on Chagas disease to assess tissues and blood specimens from endemic areas are outlined. Ultimately, the importance of ongoing surveillance is emphasized, as the future of heart transplant recipients with Chagas disease is unpredictable and the presence or reactivation of the disease requires prompt attention in an effort to prevent graft failure and death.
