Un besoin mondial d’enseignement supérieur professionnel court
Authors: Majid Zayer El 
Published: May 2016

Malgré des difficultés persistantes, le système d’enseignement supérieur professionnel court au Maroc bénéficie aujourd’hui d’un climat favorable car il répond en partie à des besoins d’une économie en constante évolution et permet, dans un contexte de fort chômage des jeunes diplômés de l’enseignement supérieur, d’offrir des opportunités d’emploi et d’insertion aux sortants. Le pays s’est engagé dans un processus continu de réformes politiques, économiques et sociales avec le déploiement de plans stratégiques sectoriels. La formation professionnelle doit encore relever quelques défis : la réorganisation de la politique d’orientation et d’information destinée aux jeunes et à leurs familles ainsi que la mise en place d’un observatoire des emplois et des qualifications.
Stochastic Collocation vial1-Minimisation on Low Discrepancy Point Sets with Application to Uncertainty Quantification
Authors: Liu Yongle , Guo Ling 
Published: May 2016

AbstractVarious numerical methods have been developed in order to solve complex systems with uncertainties, and the stochastic collocation method usingl1-minimisation on low discrepancy point sets is investigated here. Halton and Sobol' sequences are considered, and low discrepancy point sets and random points are compared. The tests discussed involve a given target function in polynomial form, high-dimensional functions and a random ODE model. Our numerical results show that the low discrepancy point sets perform as well or better than random sampling for stochastic collocation vial1-minimisation.

Abstract. The radiative role of ice clouds in the atmosphere is known to be important, but uncertainties remain concerning the magnitude and net effects. However, through measurements of the microphysical properties of cirrus clouds, we can better characterize them, which can ultimately allow for their radiative properties to be more accurately ascertained. Recently, two types of cirrus clouds differing by formation mechanism and microphysical properties have been classified – in situ and liquid origin cirrus. In this study, we present observational evidence to show that two distinct types of cirrus do exist. Airborne, in situ measurements of cloud ice water content (IWC), ice crystal concentration (Nice), and ice crystal size from the 2014 ML-CIRRUS campaign provide cloud samples that have been divided according to their origin type. The key features that set liquid origin cirrus apart from the in situ origin cirrus are higher frequencies of high IWC ( > 100 ppmv), higher Nice values, and larger ice crystals. A vertical distribution of Nice shows that the in situ origin cirrus clouds exhibit a median value of around 0.1 cm−3, while the liquid origin concentrations are slightly, but notably higher. The median sizes of the crystals contributing the most mass are less than 200 µm for in situ origin cirrus, with some of the largest crystals reaching 550 µm in size. The liquid origin cirrus, on the other hand, were observed to have median diameters greater than 200 µm, and crystals that were up to 750 µm. An examination of these characteristics in relation to each other and their relationship to temperature provides strong evidence that these differences arise from the dynamics and conditions in which the ice crystals formed. Additionally, the existence of these two groups in cirrus cloud populations may explain why a bimodal distribution in the IWC-temperature relationship has been observed. We hypothesize that the low IWC mode is the result of in situ origin cirrus and the high IWC mode is the result of liquid origin cirrus.
Wind speed response of marine non-precipitating stratocumulus clouds over a diurnal cycle in cloud-system resolving simulations
Authors: Kazil Jan , Feingold Graham , Yamaguchi Takanobu 
Published: May 2016

Abstract. Observed and projected trends in large-scale wind speed over the oceans prompt the question: how do marine stratocumulus clouds and their radiative properties respond to changes in large-scale wind speed? Wind speed drives the surface fluxes of sensible heat, moisture, and momentum and thereby acts on cloud liquid water path (LWP) and cloud radiative properties. We present an investigation of the dynamical response of non-precipitating, overcast marine stratocumulus clouds to different wind speeds over the course of a diurnal cycle, all else equal. In cloud-system resolving simulations, we find that higher wind speed leads to faster boundary layer growth and stronger entrainment. The dynamical driver is enhanced buoyant production of turbulence kinetic energy (TKE) from latent heat release in cloud updrafts. LWP is enhanced during the night and in the morning at higher wind speed, and more strongly suppressed later in the day. Wind speed hence accentuates the diurnal LWP cycle by expanding the morning–afternoon contrast. The higher LWP at higher wind speed does not, however, enhance cloud top cooling because in clouds with LWP ⪆ 50 g m−2, longwave emissions are insensitive to LWP. This leads to the general conclusion that in sufficiently thick stratocumulus clouds, additional boundary layer growth and entrainment due to a boundary layer moistening arises by stronger production of TKE from latent heat release in cloud updrafts, rather than from enhanced longwave cooling. We find that large-scale wind modulates boundary layer decoupling. At nighttime and at low wind speed during daytime, it enhances decoupling in part by faster boundary layer growth and stronger entrainment and in part because shear from large-scale wind in the sub-cloud layer hinders vertical moisture transport between the surface and cloud base. With increasing wind speed, however, in decoupled daytime conditions, shear-driven circulation due to large-scale wind takes over from buoyancy-driven circulation in transporting moisture from the surface to cloud base and thereby reduces decoupling and helps maintain LWP. The total (shortwave + longwave) cloud radiative effect (CRE) responds to changes in LWP and cloud fraction, and higher wind speed translates to a stronger diurnally averaged total CRE. However, the sensitivity of the diurnally averaged total CRE to wind speed decreases with increasing wind speed.
Visualising DEM-related flood-map uncertainties using a disparity-distance equation algorithm
Authors: Brandt S. Anders , Lim Nancy J. 
Published: May 2016

Abstract. The apparent absoluteness of information presented by crisp-delineated flood boundaries can lead to misconceptions among planners about the inherent uncertainties associated in generated flood maps. Even maps based on hydraulic modelling using the highest-resolution digital elevation models (DEMs), and calibrated with the most optimal Manning's roughness (n) coefficients, are susceptible to errors when compared to actual flood boundaries, specifically in flat areas. Therefore, the inaccuracies in inundation extents, brought about by the characteristics of the slope perpendicular to the flow direction of the river, have to be accounted for. Instead of using the typical Monte Carlo simulation and probabilistic methods for uncertainty quantification, an empirical-based disparity-distance equation that considers the effects of both the DEM resolution and slope was used to create prediction-uncertainty zones around the resulting inundation extents of a one-dimensional (1-D) hydraulic model. The equation was originally derived for the Eskilstuna River where flood maps, based on DEM data of different resolutions, were evaluated for the slope-disparity relationship. To assess whether the equation is applicable to another river with different characteristics, modelled inundation extents from the Testebo River were utilised and tested with the equation. By using the cross-sectional locations, water surface elevations, and DEM, uncertainty zones around the original inundation boundary line can be produced for different confidences. The results show that (1) the proposed method is useful both for estimating and directly visualising model inaccuracies caused by the combined effects of slope and DEM resolution, and (2) the DEM-related uncertainties alone do not account for the total inaccuracy of the derived flood map. Decision-makers can apply it to already existing flood maps, thereby recapitulating and re-analysing the inundation boundaries and the areas that are uncertain. Hence, more comprehensive flood information can be provided when determining locations where extra precautions are needed. Yet, when applied, users must also be aware that there are other factors that can influence the extent of the delineated flood boundary.
Frozen debris lobe morphology and movement: an overview of eight dynamic features, southern Brooks Range, Alaska

Published: May 2016

Abstract. Frozen debris lobes (FDLs) are elongated, lobate permafrost features that mostly move through shear in zones near their bases. We present a comprehensive overview of eight FDLs within the Dalton Highway corridor (southern Brooks Range, Alaska), including their catchment geology and rock strengths, lobe soil characteristics, surface movement measurements collected between 2012 and 2015, and analysis of historic and modern imagery from 1955 to 2014. Field mapping and rock strength data indicate that the metasedimentary and metavolcanic bedrock forming the majority of the lobe catchments has very low to medium strength and is heavily fractured, thus easily contributing to FDL formation. The eight investigated FDLs consist of platy rocks typical of their catchments, organic debris, and an ice-poor soil matrix; massive ice, however, is present within FDLs as infiltration ice, concentrated within cracks open to the surface. Exposure of infiltration ice in retrogressive thaw slumps (RTSs) and associated debris flows leads to increased movement and various stages of destabilization, resulting in morphological differences among the lobes. Analysis of historic imagery indicates that movement of the eight investigated FDLs has been asynchronous over the study period, and since 1955, there has been an overall increase in movement rates of the investigated FDLs. The formation of surface features, such as cracks, scarps, and RTSs, suggests that the increased movement rates correlate to general instability, and even at their current distances, FDLs are impacting infrastructure through increased sediment mobilization. FDL-A is the largest of the investigated FDLs. As of August 2015, FDL-A was 39.2 m from the toe of the Dalton Highway embankment. Based on its current distance and rate of movement, we predict that FDL-A will reach the Dalton Highway alignment by 2023.

Published: May 2016

The aim of the study was to evaluate the oxidative stability (TBARS method) of breast and thigh muscle after application of feed mixtures enriched by phytogenic additives. The experiment started with 150 pieces one-day-old chicks of Cobb 500 hybrid combination. They were divided into one control (C) and two experimental groups (1st EG and 2nd EG). Each group included 50 chicks. In experimental groups, feed additives were applied as followed: 100 mg.kg-1 Agolin Poultry (in the 1st EG) and 500 mg.kg-1 Agolin Tannin Plus (in the 2nd EG). Experimental broiler chickens were fed during 42 days by ad libitum. Chicken meat samples of breast and thigh muscle were analysed in the 1st day, 1st, 2nd, 3rd, 4th, 5th and 6th month of storage in frozen storage at -18 °C. We recorded positive influence on chicken meat oxidative stability in all experimental groups with application of phytogenic feed additives. Obtained results showed that applied phytogenic additives had positive influence on oxidative stability of breast and thigh muscles. At the end of frozen storage (in 6th month), we found higher malondialdehyde (MDA) values and lower oxidative stability (p <0.05) of breast muscle in control group (0.167 mg.kg-1) compared to experimental groups (from 0.150 mg.kg-1 in 1. EG to 0.155 mg.kg-1 in 2. EG). In the thigh muscle, we found similar tendency of oxidative changes as in the breast muscle. At the end of frozen storage (in the 6th month), MDA average values of thigh muscle were higher (p <0.05) in control group (0.181 mg.kg-1) compared to experimental groups (1. EG 0.164 mg.kg-1 and 2. EG 0.169 mg.kg-1). Significant differences (p <0.05) between the control and experimental groups were found from the 5th month of storage in thigh and breast muscle. Obtained results indicate positive influence of phytogenic additives applied in chicken nutrition, namely on stabilization of fatty substance to degradation processes.

Published: May 2016

Changes in the composition, physical and mechanical properties occur in grape berries during the ripening process, but the heterogeneity of the grapes harvested at different ripening stages affects the reliability of the results obtained. The characterization of the mechanical properties of grape berries seems to be an important parameter for understanding grape ripening. In this work, these changes were studied in seven grapevine varieties (Riesling, Blaufränkisch, Pinot Noir, Cerason, Malverina, Laurot, and Hibernal) harvested during six consecutive weeks. Mechanical behaviour was measured using compression and puncture tests using of TIRATEST 27025 testing machine. Skin mechanical properties were evaluated using a puncture test carried out on the equatorial side. The dependence of these properties on the chemical composition has been evaluated. These parameters of force/time curves were studied by puncture test: the berry skin break force, the needle displacement at the skin break and the berry skin break energy. The crushing force, the plate displacement at the crushing strength and the berry crushing energy were studied from force/time curves by compression test. Results of the puncture test shows that there the skin break strength and the acidity content are monotonic functions of the time. A comparison of different varieties from the point of the value of the crushing force was obtained by vertical and transversal loading. The crushing force is monotonically decreasing function of the harvesting time like the break force evaluated at the puncture test. The correlation between the skin break strength and the sugar content is significant namely for the varieties: Hibernal, Riesling, Malverina, and Cerason.

Published: May 2016

<p class="ber"><span lang="EN-GB">The study aims to explore the influential relationship between sports sponsorship and brand value dimensions (consumer trends, brand image and loyalty to the mark). Non-random sample is used and 345 single surveys have been distributed in Algeria. Non-random sampling is any other kind of sampling. Such methods are often used for speed and convenience, and also they do not require a sampling frame. The result suggested that there is a significant impact of sports sponsors on consumer trends (cognitive component, emotional component, component behavior). Besides, there is another impact of sports sponsors towards the brand image of sporting event. The study also detected the impact of sports sponsors on the brand loyalty for sponsors of sporting event. On the other hand, with respect to the differences between sample answers, the results suggested that there are differences in the trends sample about the impact of sports sponsors brand value dimensions (consumer attitudes towards the brand, brand image, loyalty to the mark) depending on the demographic and functional variables (age, sex, educational level, profession, trader type).In summary, the study recommended to activate the sports sponsorship process by various communication devices such as advertising and public relations. </span></p>
Bloom’s Taxonomy, Backward Design, and Vygotsky’s Zone of Proximal Development in Crafting Learning Outcomes
Authors: Sideeg Abdunassir 
Published: May 2016

<p>This article aims to present some fresh insights into one of the milestones in the field of education. For sixty years, Bloom’s taxonomy has been one of the most significant tools used in course design as it provides a rigorous framework for crafting learning outcomes and designing both assessment tasks and instructional activities aligned with these learning outcomes. Though not a panacea for all problems of course design and educational assessment, when meticulously understood and wisely used in a student-centered environment which integrates the taxonomy with other useful approaches and tools such as backward design and Vygotsky’s zone of proximal development (ZPD), Bloom’s taxonomy could provide an invaluable and indispensable roadmap for crafting effective learning outcomes that drive the whole process of course design. </p>

Published: May 2016

La educación preescolar es la base del desarrollo afectivo, social, cognoscitivo y psicomotor que favorece el desarrollo integral de la niñez, en el municipio de Estelí. Para desarrollar este trabajo se cuenta con 185 educadoras voluntarias (95 urbanas, 90 rurales) llamadas Educadoras Comunitarias, que atienden a 2,678 niños y niñas que equivalen al 65% de la niñez atendida en el nivel preescolar en el municipio. Para ser Educadora es un requisito contar con educación primaria aprobada. Estas educadoras trabajan en los preescolares entre 3 y 4 horas, cinco días por semana y no reciben salario. Están organizadas en el Movimiento de Educadoras de Preescolares Comunitarios (MOVEDUPCE).Esta investigación tiene como objetivo comprender las motivaciones individuales y colectivas que permiten que las educadoras comunitarias realicen una labor educativa integral con la niñez y la comunidad. Este estudio es de tipo cualitativo, se utilizaron métodos narrativos, como: grupos focales, y entrevistas abiertas. La investigación documental nos ubica en el contexto de la investigación y sus antecedentes históricos.Entre los resultados más significativos se identificaron dos tipos de motivaciones que las impulsa a trabajar con responsabilidad y compromiso: a) Las motivaciones personales que se relacionan con su comportamiento maternal que les permite proveer de amor a los niños y niñas que llegan a la escuela y proteger sus derechos con alegría y felicidad; b) La motivación colectiva relacionada con su compromiso con la comunidad y el desarrollo. Estas motivaciones les permiten sentirse parte importante de la comunidad y elevar su autoestima y valoración personal. La labor de estas educadoras comunitarias ha trascendido su rol pedagógico porque han demostrado su capacidad para autogestionar proyectos, realizar coordinaciones interinstitucionales, asumir liderazgo, y promover la participación comunitaria en la organización y movilización social para la defensa de los derechos de las niñas y de las mujeres.

Published: May 2016

É confiada ao sistema escolar Português a função primordial de contribuir para a compreensão e preservação do património, sendo que a educação patrimonial é uma componente importante da Educação Artística em Portugal. Um problema central no seu estudo é a falha do sistema escolar na consecução das finalidades atrás descritas, porque o seu ensino é feito de uma forma muito etnocêntrica*, ignorando as culturas minoritárias e as culturas não Europeias. Este artigo explora diversas abordagens educativas e apresenta estratégias utilizadas por professores de Cursos de Arte da Formação Inicial e Mestrado, que têm trabalhado com o Departamento de Educação Artística da Escola Superior de Educação, do Instituto Politécnico de Viana do Castelo (ESEVC), Portugal. Os presentes Projectos tiveram as seguintes finalidades: (1) reflectirsobre educação artística usando literatura predominantemente Anglo-Saxónica; (2) desenvolver uma prática reflexiva; e (3) utilizar os princípios fundamentais da investigação educativa. No final apresentam-se algumas conclusões e implicações para o contexto da educação em geral e especificamente para o Projecto Internacional em curso entre a ESEVC e Universidades de Ensino Superior do Brasil (e.g. Belo Horizonte, Uberaba & Campinas), intitulado Experiências D'Além Mar: Estudos Luso-Brasileirossobre Cultura, Educação e Educação em Arte.

Clement Greenberg pelo avesso
Authors: Butkus Vitor 
Published: May 2016

Este artigo é o resultado de um esforço reflexivo tendo como tema o crítico de arte norte-americano Clement Greenberg, sua obra e sua atuação no campo das artes. Esse autor de posições teóricas polêmicas é, aqui, analisado pelo seu antes e pelo seu depois. O contexto cultural em que se produziu a sua escrita é visado, não como causa, mas como fornecedor de problemas teóricos aos quais a crítica greenberguiana responderá. Apontando esse rumor teórico, contemporâneo à atividade do autor, e atravessado por questões extra-artísticas, propomos um distanciamento crítico através do qual se busca a compreensão dos principais textos de Greenberg. A plataforma analítica estabelecida pela contextualização histórica também é experimentada em um breve levantamento do legado desses textos, observando-se como as reações ao formalismo ainda reverberam na contemporaneidade.Palavras-chave : teoria da arte, crítica de arte, integração teórico-prática, Clement Greenberg
Percorrendo o labirinto com Marcel Duchamp
Authors: Cordeiro Flávia Dutra 
Published: May 2016

Demonstrar como as obras do artista Marcel Duchamp se inserem na Arte Contemporânea e como a existência de vários dos seus fragmentos, esboços e estudos são pontos centrais para a construção de mundos de devaneios que trazem conceitos intercalados de forma labiríntica. Os estudos e obras de Duchamp são parte integrante de um labirinto que percorre o espaço-tempo e cujas marcas estão fortemente associadas ao modo de se pensar a Arte Contemporânea quando inclui o outro. O que perpassa pela abrangência do outro como co-artista carrega em si algo de subjetivo, o que tornou possível aproximarem-se várias correntes de pensamento, fazendo com que eles se encontrassem através desta pesquisa cujos conceitos foram sendo delineados durante a sua realização. Analisar e pesquisar faz parte do processo desenvolvido e traz consigo a proximidade entre as obras de Duchamp e o que tenho feito durante alguns anos através da Arte.Palavras-chave : Arte Contemporânea.
