One of the proposals to contribute to the achievement of this goal is the expansion of the school day. Although the debates on the subject can refer to an idea of recent and innovative proposal, in Brazil, experiences with full-time education focused for less economically favored social classes are realities for at least five decades. During this period, there were beginnings and closures cycles with these experiences. However, although there are several debates between advocates and opponents of this educational policy, there are not so many researches that address the impacts of these activities for teachers and students involved in these proposals. Through research that discusses and reflects on expansion programs of the school day, it is expected to be possible to ascertain whether the practice performed contributes to the goals proposed for the program. In this sense, through this study, it is intended to determine whether the activities in the area of environmental education, linked to programs of expansion of the school day in state schools of Cascavel-PR, contribute to the achievement of the main objective of the journey expansion programs school: reduce educational inequalities (BRAZIL, 2010). Therefore, Scientific Literacy indicators will be used to enable verifying the level of scientific literacy of students in the subjects addressed in the extracurricular activities they are enrolled. Analysis of the legislation was made which regulates the expansion of the school day, in the proposals of activities in the field of environmental education and also interviews with teachers and students involved in the activities. The different stages of the research show that some gaps in the legislation that regulates the extracurricular activities can negatively impact the development and results of the activities. Among the five analyzed activities, it was possible to realize the contribution of only one for Scientific Literacy of the students. It is noticed that there is still a long way to go in order that the extracurricular activities, at least in most cases, contribute to student learning and, consequently, for education. / Proporcionar uma educação que possa formar cidadãos críticos, atuantes e transformadores da sociedade, longe de ser um desafio contemporâneo, há muito permeia debates e inspiram teorias educacionais. Uma das propostas que visam a contribuir para o alcance desse objetivo é a ampliação da jornada escolar. Embora os debates acerca do tema possam remeter a uma ideia de proposta recente e inovadora, no Brasil, experiências com o ensino em tempo integral voltado para classes sociais menos favorecidas economicamente são realidades há pelo menos cinco décadas. Nesse período, houve inícios e encerramentos de ciclos com essas experiências. No entanto, embora haja vários debates entre os defensores e opositores dessa política educacional, não há muitas pesquisas que contemplem os impactos dessas atividades para professores e alunos envolvidos nessas propostas. Através de pesquisas que discutam e reflitam sobre programas de ampliação da jornada escolar, espera-se ser possível verificar se a prática realizada contribui para os objetivos propostos para o programa. Neste sentido, através da presente pesquisa, pretendeu-se verificar se as atividades na área de Educação Ambiental, vinculadas aos programas de ampliação de jornada escolar nas escolas estaduais de Cascavel-PR, contribuem para o alcance do principal objetivo dos programas de ampliação da jornada escolar: diminuir as desigualdades educacionais (BRASIL, 2010). Para tanto, os indicadores da Alfabetização Científica serão utilizados para possibilitar verificar o nível da Alfabetização Científica dos alunos nos temas abordados nas atividades em contraturno em que estão matriculados. Foram realizadas análises da legislação que regulamenta a ampliação da jornada escolar, nas propostas das atividades na área de Educação Ambiental e também entrevistas com professores e alunos envolvidos nas atividades. As diferentes etapas da pesquisa mostraram que algumas lacunas na legislação que regulamenta as atividades em contraturno podem impactar de forma negativa o desenvolvimento e resultados das atividades. Dentre as cinco atividades analisadas, foi possível perceber a contribuição de apenas uma para a Alfabetização Científica dos alunos. Percebe-se que ainda há um longo caminho a ser percorrido para que as atividades contraturno, pelo menos em sua maioria, contribuam para aprendizagem dos alunos e, consequentemente, para a Educação

L'industrie du ciment est l'une des principales sources d'émission de dioxyde de carbone. L'industrie mondiale du ciment contribue à environ 7% des émissions de gaz à effet de serre dans l'atmosphère. Afin d'aborder les effets environnementaux associés à la fabrication de ciment exploitant en permanence les ressources naturelles, il est nécessaire de développer des liants alternatifs pour fabriquer du béton durable. Ainsi, de nombreux sous-produits industriels ont été utilisés pour remplacer partiellement le ciment dans le béton afin de générer plus d'économie et de durabilité. La performance d'un additif de ciment est dans la cinétique d'hydratation et de la synergie entre les additions et de ciment Portland. Dans ce projet, deux sous-produits industriels sont étudiés comme des matériaux cimentaires alternatifs: le résidu de silice amorphe (RSA) et les cendres des boues de désencrage. Le RSA est un sous-produit de la production de magnésium provenant de l'Alliance Magnésium des villes d'Asbestos et Thedford Mines, et les cendres des boues de désencrage est un sous-produit de la combustion des boues de désencrage, l'écorce et les résidus de bois dans le système à lit fluidisé de l'usine de Brompton située près de Sherbrooke, Québec, Canada. Récemment, les cendres des boues de désencrage ont été utilisées comme des matériaux cimentaires alternatifs. L'utilisation de ces cendres comme matériau cimentaire dans la fabrication du béton conduit à réduire la qualité des bétons. Ces problèmes sont causés par des produits d'hydratation perturbateurs des cendres volantes de la biomasse quand ces cendres sont partiellement mélangées avec du ciment dans la fabrication du béton. Le processus de pré-mouillage de la cendre de boue de désencrage avant la fabrication du béton réduit les produits d'hydratation perturbateurs et par conséquent les propriétés mécaniques du béton sont améliorées. Les approches pour étudier la cendre de boue de désencrage dans ce projet sont : 1) caractérisation de cette cendre volante régulière et pré-humidifiée, 2) l'étude de la performance du mortier et du béton incorporant cette cendre volante régulière et pré-humidifiée. Le RSA est un nouveau sous-produit industriel. La haute teneur en silice amorphe en RSA est un excellent potentiel en tant que matériau cimentaire dans le béton. Dans ce projet, l'évaluation des RSA comme matériaux cimentaires alternatifs compose trois étapes. Tout d'abord, la caractérisation par la détermination des propriétés minéralogiques, physiques et chimiques des RSA, ensuite, l'optimisation du taux de remplacement du ciment par le RSA dans le mortier, et enfin l'évaluation du RSA en remplacement partiel du ciment dans différents types de béton dans le système binaire et ternaire. Cette étude a révélé que le béton de haute performance (BHP) incorporant le RSA a montré des propriétés mécaniques et la durabilité, similaire du contrôle. Le RSA a amélioré les propriétés des mécaniques et la durabilité du béton ordinaire (BO). Le béton autoplaçant (BAP) incorporant le RSA est stable, homogène et a montré de bonnes propriétés mécaniques et la durabilité. Le RSA avait une bonne synergie en combinaison de liant ternaire avec d'autres matériaux cimentaires supplémentaires. Cette étude a montré que le RSA peut être utilisé comme nouveaux matériaux cimentaires dans le béton. / Abstract : Cement manufacturing industry is one of the carbon dioxide emitting sources. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmosphere. In order to address environmental effects associated with cement manufacturing and constantly depleting natural resources, there is necessity to develop alternative binders to make sustainable concrete. Thus, many industrial by-products have been used to partially substitute cement in order to generate more economic and durable concrete. The performance of a cement additive depends on kinetics hydration and synergy between additions and Portland cement. In this project, two industrial by-products are investigated as alternative supplementary cementitious materials (ASCMs), non-toxic amorphous silica residue (AmSR) and wastepaper sludge ash (WSA). AmSR is by-product of production of magnesium from Alliance Magnesium near of Asbestos and Thetford Mines Cities, and wastepaper sludge ash is by-product of combustion of de-inking sludge, bark and residues of woods in fluidized-bed system from Brompton mill located near Sherbrooke, Quebec, Canada. The AmSR is new industrial by-products. Recently, wastepaper sludge ash has been used as cementitious materials. Utilization of these ashes as cementitious material in concrete manufacturing leads to reduce the mechanical properties of concretes. These problems are caused by disruptive hydration products of biomass fly ash once these ashes partially blended with cement in concrete manufacturing. The pre-wetting process of WSA before concrete manufacturing reduced disruptive hydration products and consequently improved concrete mechanical properties. Approaches for investigation of WSA in this project consist on characterizing regular and pre-wetted WSA, the effect of regular and pre-wetted WSA on performance of mortar and concrete. The high content of amorphous silica in AmSR is excellent potential as cementitious material in concrete. In this project, evaluation of AmSR as cementitious materials consists of three steps. Characterizing and determining physical, chemical and mineralogical properties of AmSR. Then, effect of different rates of replacement of cement by AmSR in mortar. Finally, study of effect of AmSR as partial replacement of cement in different concrete types with binary and ternary binder combinations. This study revealed that high performance concrete (HPC) incorporating AmSR showed similar mechanical properties and durability, compared to control mixture. AmSR improved mechanical properties and durability of ordinary concrete. Self-consolidating (SCC) concrete incorporating AmSR was stable, homogenous and showed good mechanical properties and durability. AmSR had good synergy in ternary binder combination with other supplementary cementitious materials (SCMs). This study showed AmSR can be use as new cementitious materials in concrete.

Ce travail s'intéresse à l'organisation fonctionnelle du système sensorimoteur. La somatotopie est une caractéristique essentielle de M1, mais l'organisation fonctionnelle des autres aires motrices (PM, SMA, et IPL) n'est pas encore clairement établie. Premièrement, nous avons exploré par IRMf l'organisation fonctionnelle sensorimotrice chez des sujets sains exécutant des mouvements simples. Nos résultats montrent que les représentations motrices sont organisées selon des synergies musculaires et qu'une organisation somatotopique, différente de celle de M1, existe dans l'IPL. Bien qu'elle fasse régulièrement l'objet de critiques, la DES est à la base de la plupart de nos connaissances sur le cortex moteur, que confirme les études en IRMf. Ainsi, en réponse au débat en cours, nous avons passé en revue les arguments récents confortant la confiance que nous pouvons accorder à la DES. Des études récentes concluent à l'implication du PPC dans l'intention motrice, mais le débat reste ouvert sur la relation entre intention et préparation motrices. Certains prétendent que l'intention serait le sous-produit de la préparation motrice, ne laissant aucune place à la volonté dans le contrôle moteur. Pour étudier cette question, nous avons mis en place une expérience comportementale, incluant des tâches de réaction simple et de Libet pour comparer les deux processus cognitifs. Nos résultats montrent que le temps de réaction entre intention interne et réaction motrice est égal à celui séparant commande externe et réaction motrice. Cela contredit donc l'affirmation selon laquelle la préparation motrice précèderait l'intention et donc que l'intention émergerait du processus d'intention motrice / In this thesis, I am interested in the functional organization of human cortical sensorimotor system. Somatotopy is the prominent structure of the functional organization in sensory and motor cortex. However, the structure of the functional organization in higher order motor area, such as IPL is little known. Therefore, in the first part, I study the functional organization of human sensory- and motor- related brain regions using fMRI, by guiding healthy subjects to perform simple repetitive movements of different body parts. Our results demonstrate that, 1) motor synergy is the neural basis represented in the motor cortex; and 2) somatotopic organization also exists in IPL but with different structure from that of sensorimotor cortex. Despite continuous criticism on DES, most of our primitive knowledge of the sensorimotor cortex comes from DES studies, and our fMRI result supports the findings of DES. In response to the ongoing debate on DES, in the second study, we review recent evidence to re-establish the confidence on DES. Accumulating evidence indicates that PPC is related to the emergence of motor intention. However, debate on the relation between motor intention and preparation never stops, some claims that motor intention is the byproduct from motor preparation, thus denying the volition of human motor control. Besides this complexity, we design a straightforward behavior experiment, including simple reaction task and Libet task, in order to compare the cognitive process of motor preparation and motor intention. Our result shows that RT from internal motor intention to motor output is equal to the RT from external cue to motor output, thus rejecting the possibility that motor preparation starts in advance of motor intention and doesn't support that motor intention arises from the process of motor intention

Le pouce opposable de la main joue un rôle essentiel dans le comportement humain, permettant une prise bien plus précise que celle des singes avec les pouces opposables. Comment le cerveau contrôle t-il les mains aussi précisément? Dans le cadre de cette thèse, nous avons étudié comment différentes régions du cerveau dédiées au contrôle moteur, en particulier le cortex moteur (M1) et l’aire motrice supplémentaire (AMS), contribuent à une pince pouce-index précise. Les résultats de nos études révèlent que des neurones dans l’AMS, en complément de ceux dans M1, communiquent directement avec les motoneurones de la moelle épinière contrôlant les muscles de la main. De plus, SMA communique aussi efficacement que M1 avec les muscles de la main, alors que chez le singe, celle avec M1 est plus efficace. Cette différence fonctionnelle dans la voie AMS-muscles entre le singe et l’Homme pourrait expliquer la plus grande capacité de ce dernier à contrôler finement la force produite par les doigts. / The human hand's opposable thumb plays a large role in human behavior, allowing for a grip far more precise than that of monkeys with opposable thumbs. However, it isn't well understood how the brain controls the hands in such a precise way. In these studies, we investigate how different parts of the brain dedicated to motor tasks, in particular the motor cortex (M1) and the supplementary motor area (SMA), contribute to a precise thumb-index finger grip. Our experiments suggest that some neurons in the SMA, in addition to those well-described in M1, may connect directly to the motoneurons in the spinal cord controlling the hand muscles. Moreover, we found that SMA communicates with the hand muscles as efficiently as M1, while in monkeys, SMA communicates less efficiently than M1. This functional difference in the SMA-muscles pathway between monkey and human may account for the higher capacity of the latter to precisely control the force produced by digits.

This thesis is focused on products used to cover the needs of the people in retirement in the conditions of the Czech Republic, which can be a suitable complement to the constantly decreasing values of the retirement pension paid by the State. At first I will describe the current situation of the Czech pension system and its compulsory transformation into a multi-pillar system. The following chapters are devoted to analyzing individual products in terms of making savings for retirement. In the last chapter I compare different products and try to find out the best way how to secure individuals savings for life in the retirement according to a particular state revenues and expenditures.

Les régimes de protection sociale complémentaire constituent des outils à la disposition des employeurs afin de fidéliser leurs salariés. S’inspirant directement des principes encadrant le fonctionnement des régimes de base de la sécurité sociale, l’opération de prévoyance se caractérise, en partie, par une forte dimension collective. La création et la mise en oeuvre des couvertures de prévoyance et de frais de santé s’accompagnent de la poursuite d’idéaux d’égalité, de solidarité et de mutualisation. L’adoption des textes fondateurs en la matière,les lois Evin et Veil, a conduit à l’institution de mécanismes propres à l’opération de prévoyance reflétant cette dimension collective. L’influence du droit des assurances est certaine et sa maîtrise indispensable pour assurer la pérennité des mécanismes de protection sociale d’entreprise. Terrain d’application de droits divers, l’opération de prévoyance se caractérise par la complexité des relations entre ses intervenants et des règles régissant son support, le contrat de d’assurance de groupe. L’optimisation de son coût pour l’employeur est au prix d’un effort de conciliation de ces différents instruments / Supplementary social protection schemes are tools which employers can decide to utilize inorder to retain their employees. Corporate social protection systems are directly based on the principles which rule the functioning of the basic social security scheme. Understandably, they are characterized by a strong collective dimension. Design and implementation of corporate social protection are therefore associated with the pursuit of ideals of equality,solidarity and risks or resources pooling. The enactment of the founding legislation in this area – i.e. the Evin and Veil Acts* – led to the setting up of mechanisms peculiar to corporate social protection systems and whose very existence is revealing of this collective dimension.The influence of insurance law is indisputable and having full command of it is naturally instrumental in ensuring the viability of corporate social protection. Corporate social protection systems indeed find themselves at the crossroad of several legal domains. They are therefore distinguished by the complexity of the relations between their actors as well as that of the rules governing the collective insurance contract through which they are implemented. Optimizing its cost is a performance employers can only achieve through a careful conciliation of these instruments.

This project explored the question of whether or not the employment of off-duty police officers should be regulated. It includes two surveys, a statewide survey of agency regulations and a survey of Fontana Police Department personnel.

El objetivo de este estudio fue encontrar los factores de riesgo para la baja adherencia a la suplementación con multimicronutrientes (MMN) en niños de 6 a 35 meses de edad. Se analizó una base de datos secundaria de la vigilancia centinela realizada durante los años 2009-2011 en las regiones de Apurímac, Ayacucho y Huancavelica por el Centro Nacional de Epidemiologia, Prevención y Control de Enfermedades del Perú (CDC). Se incluyeron los datos demográficos además de otras variables que se recogieron mes a mes durante la vigilancia. Estas son si recibió consejería nutricional, si asistió a la sesión demostrativa de preparación de alimentos con MMN, si percibió alguna mejoría en el niño, si el niño presentó algún evento adverso relacionado al consumo de MMN, si recibió visitas domiciliarias, y el alimento en el que se agregó los MMN. Para el análisis estadístico se usó la regresión de ecuaciones de estimación generalizadas (GEE). Los resultados que se encontraron son que asistir a la sesión demostrativa (p=0.005), que el niño presente eventos adversos relacionados a la ingesta de MMN durante los seis primeros meses de suplementación (p<0.001) y agregar los MMN en alimentos líquidos (p=0.001) disminuyen la adherencia a la suplementación en 1.27%, 17.00% y 1.51% respectivamente. Residir en Huancavelica (p<0.001) y que la madre note a su niño más despierto (p=0.039) incrementan la adherencia en 2.51% y 0.95% respectivamente. Concluimos que se deben realizar intervenciones que aborden estos factores de riesgo, y recomendamos que se realicen más estudios en esta área. / The objective of this study was to find the risk factors for poor adherence to multimicronutrient supplementation (MMN) in children 6 to 35 months of age. A secondary database of sentinel surveillance carried out during the years 2009-2011 in the regions of Apurímac, Ayacucho and Huancavelica by the National Center for Epidemiology, Prevention and Disease Control of Perú (CDC) was analyzed. Demographic data was included in addition to other variables that were collected month by month during the surveillance. These are if they received nutritional counseling, if they attended the food preparation demonstration session with MMN, if they perceive any improvement in the child, if the child presented any adverse event related to MMN consumption, if they received home visits, and the food in which the MMNs were added. Regression of generalized estimating equations (GEE) was used for statistical analysis. The results that were found are that attending the demonstration session (p = 0.005), that the child presents adverse events related to the ingestion of MMN during the first six months of supplementation (p <0.001) and adding MMN in liquid foods (p = 0.001) decrease adherence to supplementation by 1.27%, 17.00% and 1.51% respectively. Residing in Huancavelica (p <0.001) and having the mother notice the child more awake (p = 0.039) increases adherence by 2.51% and 0.95% respectively. We conclude that interventions that address these risk factors should be performed, and we recommend that further studies be conducted in this area. / Tesis

Lentsoane uses the title of his narrative to highlight the theme. Special attention is paid to this. The suspense is captured in the clash between the traditional attitude to life held by the Bapedi and the modem philosophy of life held by the younger generation. Lentsoane effectively uses the concept of a journey to convey his message to his reader. The visit of the antagonist Kgoteledi to the homeland is especially important in this regard, as her family there is conservative and thus strongly supports her actions. But it is also here that she becomes aware of change. Other important techniques used by Lentsoane are: contrast, symbolism, shifting of focus, mirrorimages, naming, summary and retardation, foreshadowing, but also the reference to related matters. This latter technique has an important emphasising function. Although conflict is emphasised all the time, the climax is reached with the announcement that Mihloti, Dikgoneng's girlfriend, is pregnant. The mother (and therefore also the rest of the family) hereby accept that change has also become part of their lives. Kgoteledi comes to terms with the situation and passes away. AFRIKAANS : In hierdie verhandeling word Lentsoane se novelle, Megokgo ya Lethabo, as 'n liefdesverhaal besktyf waarin die liefdesverhouding tussen die minnaars nie deur die jongman se familie goedgekeur word nie, omdat die jong meisie lid van 'n ander etniese groep is. Die beskrywings model wat vir die ondersoek gevolg word, is 'n aangepaste narratologiese model. Boonop word slegs twee van die struktuurlae ondersoek, nl. die inhouds- en die samestellingslae. In die beskrywing van die inhoudslaag is die vier epiese elemente, karakter, handeling, tyd en plek, noukeurig nagegaan, en t.o.v. die onderwerp wat die outeur gekies het, beskryf. Die onderwerp bepaal die onderlinge verhouding tussen die verskillende karakters, en verdeel die handeling in drie groot aksiekategorieë, t.w. die liefdesverhouding, die besware van die jongman se familie, en die uiteindelike troue. Die tydsbegrip word omskryf in terme van 'n tydstip, tydsverloop en tydsomstandighede. Vir die beskrywing van die samestellingslaag van die werk is daar twee kernbegrippe wat uitgelig word, nl. die temabegrip en die tegniek begrip wat 'n verhoudingsbegrip is en nie eenduidig in verwysing is nie. Die tema wat hier vooropgestel word, is die van verandering, en slaan op die voortdurende verandering in die lewe van mense en kulture. Die karakter van die protagonis, Dikgoneng, word in terme van noodsaaklike en bykomende kenmerke beskryf. Die noodsaaklike kenmerke hou met die verhaalsoort of genre verband, terwyl die outeur met die bykomende kenmerke sy Ieser tot vereenselwiging met die protagonis oorhaal. Die antagonis word slegs t.o.v. die noodsaaklike kenmerke beskryf. Lentsoane gebruik die verhaaltitel as 'n belangrike outeursmiddel om die tema van sy werk na vore te bring. Besondere aandag word hieraan afgestaan. Die spanningselement lê opgevang in die botsing tussen die tradisionele lewensopvattings van die Bapedi en die modeme lewensbeskouing van die jong geslag. Lentsoane maak effektief van die reisbegrip gebruik om sy boodskap aan sy leer tuis te bring. Hier is dit veral die antagonis, Kgoteledi, se besoek aan die tuisland, wat belangrik is, omdat haar familie daar behoudende mense is, en haar dus in haar saak sterk steun. Maar dis dan ook hier waar sy van verandering bewus raak. Belangrike ander tegnieke wat Lentsoane gebruik, is kontrastering, simboliek, fokusverskuiwing, spieëlbeeldstelling, naamgewing, tydsversnelling en vertraging, vooruitskouring, maar veral die verwysing na verwante geleenthede wat 'n sterk beklemtoningsfunksie het. Hoewel konflik deurentyd aan die orde is, word die hoogtepunt met die aankondiging bereik dat Mihloti (Dikgoneng se nooi) swanger is. Die moeder (en daarom ook die res van die familie) aanvaar hiermee dat verandering ook deel van hulle lewens geword het. Kgoteledi berus haar hierin en sterwe. / Dissertation (MA)--University of Pretoria, 1999. / African Languages / unrestricted
