Genus bland tomtar och troll : Så framställs kön i sagoböcker

Eriksson, Veronika, Norberg, Tanja January 2013 (has links)
I denna studie studeras sex sagoböcker för barn ur ett genusperspektiv. Studien syftar till att undersöka och jämföra hur kön framställs och hur fördelningen mellan könen ser ut i sagoböcker ur serien Bland tomtar och troll. Böckerna är utgivna 1966, 1974, 1983, 1993, 2003 och 2012. För att besvara studiens frågeställningar har en kvantitativ innehållsanalys och kvalitativ textanalys genomförs. Vi har räknat förekomsten av båda könen och studerat vad könen framställs med för egenskaper. Resultatet av denna studie visar att det finns en förändring mellan fördelning och förekomst av könen från 1966 till 2012, då det 2012 till skillnad mot tidigare finns nästan lika många kvinnliga karaktärer som manliga. Flickor har fått en mer framträdande roll och framställs med egenskaper som tidigare varit förbehållna pojkar. Pojkar framställas fortfarande som äventyrliga och modiga. Även om det skett en förändring från 1966 är fortfarande manliga karaktärer i majoritet 2012 och traditionella könsroller är fortsatt framträdande.

The feat is understood here how the official public description of the governmental action, appreciated and diffused as a form of legitimation, and practice from the power of State and a specific administration. We realize that the second government of Cid Ferreira Gomes in state of Ceará operate a notion of modernization how a standard of development, creating at the same time a new shape of exposition of administrative realizations in the direction and adept system a codified lore to all that are out of a imediate production. We also understand that the news, as an institutional action, construct the feat always as positive facts, creating a short of curriculum for the State and the government and appropriating the politic culture based in the image´s relevance and validation through the mass communication. / Observando a realidade textual da notícia como objeto sociológico, o trabalho em questão discute os modos pelos quais um governo estadual produz uma imagem de si e de seu papel por meio de narrativas oficiais de noticiamento.

Por feito, entende-se aqui a descrição pública e oficial de uma ação governamental, valorizada e difundida como forma de legitimação das práticas do poder do Estado e de uma gestão específica. Percebe-se, assim, que o segundo governo de Cid Ferreira Gomes, no Ceará, opera uma noção de modernidade como bandeira do desenvolvimento, criando, ao mesmo tempo, um novo formato de exposição das realizações administrativas no sentido de um sistema perito – um saber codificado para todos os que estão fora de sua produção imediata. Compreende-se, também, que a notícia, como ação institucional, constrói os feitos sempre como fatos positivos, criando uma espécie de curriculum para o Estado e para o governo e apropriando-se de uma cultura política fundada na relevância da imagem, da validação por meio da comunicação massiva.

Développement d’un prototype préindustriel de thermofrigopompe de petite à moyenne puissance / Development of a pre-industrial prototype of a heat pump for simultaneous heating and cooling small to medium heating power

Ghoubali, Redouane 28 November 2013 (has links)
Dans le contexte actuel de durcissement de la réglementation thermique visant à améliorer l’efficacité énergétique des bâtiments, il est nécessaire de repenser les installations de chauffage, de rafraîchissement et d’eau chaude sanitaire. Un système thermodynamique multifonction, appelé thermofrigopompe (TFP), produisant simultanément de l’énergie frigorifique et calorifique, semble alors une solution intéressante. L’emploi d’un fluide frigorigène à faible potentiel de réchauffement global (le GWP exprimé en émissions équivalentes de CO2), dans les machines frigorifiques, permet de répondre de manière efficace à la problématique de réduction des émissions de gaz à effet de serre. Cette thèse présente un prototype préindustriel de thermofrigopompe utilisant le propane comme fluide frigorigène. Le propane (R290) est intéressant d’abord pour son faible impact environnemental (ODP nul et GWP100ans =3) et pour ces performances énergétiques. Le prototype est le fruit d’une collaboration entre le Pôle cristal, centre technique froid et génie climatique de Dinan, et le laboratoire LGCGM de Rennes. Une nouvelle architecture du circuit frigorifique de la TFP est proposée avec une réduction significative du nombre d’électrovannes. Cette architecture permet une récupération efficace de la charge en fluide frigorigène lors des basculements entre les différents modes. Les besoins en chauffage, rafraîchissement et eau chaude sanitaire de trois types de bâtiments situés dans différents climats sont obtenus par simulation sous TRNSYS. La nature du bâtiment ainsi que le climat influencent fortement le caractère simultané des besoins. Un indicateur de besoins simultanés (TBS) est proposé afin d’identifier le bâtiment le plus adapté à une solution de production simultanée. Des essais en chambre climatique ont permis de valider le fonctionnement du prototype et de caractériser ses performances. Ces résultats expérimentaux ont servis à calibrer les modèles de composants et de machines frigorifiques pour chaque mode de fonctionnement développés avec le logiciel EES. Un bâtiment résidentiel collectif et un immeuble de bureaux ont été choisis dans l’étude comparative, afin d’évaluer l’influence de la nature des besoins sur les performances de la TFP. Les performances annuelles simulées par la méthode de corésolution (EES-TRNSYS) de la TFP sont comparées à une solution référence qui combine une PAC air/eau réversible pour le chauffage, et le rafraîchissement et un ballon thermodynamique pour l’ECS. Les résultats des simulations des performances saisonnières ont démontré que la piste des bureaux est intéressante dans le cas de zones nécessitant un fort besoin en rafraîchissement tout au long de l’année. / In the current context of hardening of thermal regulations to improve the energy efficiency of buildings, it is necessary to reconsider the heating, cooling and domestic hot water installations. A multifunctional heat pump system for simultaneous heating and cooling (HPS), which simultaneously produces cooling and heating energy, seems to be an interesting solution. The use of a refrigerant with low global warming potential (GWP expressed in equivalent emissions of CO2) in the refrigeration machinery can respond effectively to the problem of reducing greenhouse gas emissions. This work presents a pre-industrial prototype of HPS using propane as refrigerant. Propane (R290) is interesting firstly for its low environmental impact (zero ODP and GWP100 = 3) and for the energy performance. The prototype is the result of the collaboration between the Technical Centre for refrigeration and HVAC, Pôle Cristal and LGCGM laboratory. A new architecture of the refrigerant circuit of the HPS is proposed with a significant reduction in the number of valves. This architecture allows for efficient recovery of the refrigerant charge when switching between modes. The needs for heating, cooling and domestic hot water for three types of buildings in different climates are obtained by simulation using TRNSYS. The nature of the building and climate strongly influence the simultaneous nature of the needs. A ratio of simultaneous needs (RSN) is proposed to identify the most suitable building for the simultaneous production of heating and cooling energy. Climate chamber tests were used to validate the operation of the prototype and characterize its performance. These experimental results were used to calibrate the models of components and refrigerating machines for each operation developed with EES software. A collective residential building and an office building were selected in the comparative study, in order to evaluate the influence of the nature of the requirements on the performance of the HPS. Annual performance simulated by the co-solving method (EES-TRNSYS) of HPS is compared to a reference solution that combines a reversible air / water heat pump for heating, cooling and thermodynamic water heater for domestic hot water. The simulation results of the seasonal performance showed that the office building is interesting in the case of areas requiring a strong need for refreshment throughout the year.

L'efficacité de la dépense publique en France : enjeux, bilan et perspectives / the effectiveness of public expense in France : stakes, assessment and prospects

Kharrouby, Samir 14 December 2015 (has links)
La loi organique n° 2001-692 du 1er août 2001 relative aux lois de finances (LOLF) a profondément transformé l’architecture budgétaire et comptable de l’Etat. A travers ce dispositif juridique, la France a amorcé un processus de modernisation de ses finances publiques consacrant une nouvelle conception de la gestion budgétaire et comptable de l’État inspirée des techniques de gestion de l’entreprise privée. Le décret 2012-1246 du 7 novembre 2012 relatif à la gestion budgétaire et comptable publique est venu confirmer une reforme comptable qui s’inscrit dans la démarche d’ensemble des finances publiques de l’État français. Cette reforme budgétaire et comptable conçue comme un préalable à la reforme de l’État vise essentiellement l’amélioration de l’efficacité de la dépense publique. Désormais, à la logique de moyens se substitue une gestion axée sur les résultats et la performance à même de mesurer l’efficacité de toute dépense publique en fonction d’objectifs fixés à priori / The Constitutional bylaw n° 2001-692 of 1st August, 2001 on budgets acts (LOLF) has deeply transformed the State’s budgetary and accounting structure. Through this legal device, France has begun a process of modernization of its public finances dedicating a new conception of the State’s budgetary and accounting management inspired by techniques of the private enterprise. Decree n ° 2012-1246 of 7th November, 2012 on the public budget and accounting management confirmed the accounting reform which is part of the global approach of public finances of French State. From now on, the new conception of budgetary management leans on a budgeting centered on the performance, dedicating a transition from logic of means to logic of results in the public spending. In parallel to that, Parliament sees itself confided an important place and role. Its power in the budgetary subject was strengthened.This budgetary and accounting reform conceived as prerequisite to the State’s reform, to essentially aim the improvement effectiveness of the public spending. From now on, logic of means is substituted by a management centered on the results and performance, able to measure the effectiveness of any public spending, according to objectives fixed in priori

Effects of the Consolidated Appropriations Act of 2012 Pell Grant Eligibility Requirements on Enrollment in Community Colleges

Wilson, Tracy Kathleen 06 May 2017 (has links)
Pell Grant funding is without question foundational to the American community college mission – providing access to higher education to over 9 million students. Pell Grants are particularly important in the 2-year sector, where such a large number of students are from low-income socioeconomic areas. In December 2011, then-President Obama signed into law the Consolidated Appropriations Act (2012) which significantly changed the Pell Grant program for college students by making 3 major changes to the eligibility criteria for Pell Grants. The purpose of this study was to examine the impact of these 3 changes at the national, state, and local level to estimate the impact felt by colleges and students across the United States. This quantative study utilized data from the National Center for Educational Statistics (NCES) Integrated Postsecondary Data System (IPEDS) as well as from a mid-sized urban college located in the state of Minnesota. Both regression analysis and seasonal time decomposition techniques were conducted to determine the estimated number and amount of Pell Grant award post Act compared to actual. The findings of this study indicated a significant correlation between the model and the output when used with national and local data. Not all of the state models produced significant results.
