Hur återspeglar läroböckerna tysk språkkultur i valet av tilltal? : En studie av tyska 1 och tyska 3.

Gütter, Ulrich January 2014 (has links)
Syftet med detta arbete är att visa hur tilltalet gestaltas i vardera tre läroböcker för gymnasieskolans nybörjartyska, tyska 1, och fortsättningstyska från grundskolan, tyska 3. Tilltalet i tyska summeras i orden Sie, som på svenska betyder ni, och du som i överensstämmelse med svenskan heter du. För att ta reda på hur tilltalet framställs beräknas dels andelen Sie- respektive du-dialoger, dels andelen tilltalsord i undersökta dialoger, en kvantitativ undersökning. Dessutom undersöks i varje lärobok hur olika åldersgrupper finns representerade i konversationer. Arbetet studerar även kvalitativa data. Ger böckerna instruktioner kring hur tilltalet i allmänhet bör praktiseras? I enskilda frågor observeras skillnader mellan de två språknivåerna. Resultaten visar att samtliga böcker i nybörjartyska tar upp tilltalsfrågan och varierar kommunikationen mellan olika åldersgrupper. I fortsättningstyska tar endast en lärobok upp tilltalet medan viss åldersvariation presenteras i ett läromedel. Presentationen av tilltalet visar överlag brister och lämnar frågor öppna för lärare och elev. Vad beträffar procentuellt utfall i dialoger och tilltalsord är det svårt att dra slutsatser om du- eller Sie-tilltal vinner mark på någon av språknivåerna. Hänsyn måste här även tas till åldersrepresentationen i böckerna vilken tenderar påverka resultatet. Tilltalet är en del av den tyska språkkulturen och läroboken bör uppmärksamma det i enlighet med Ämnesplan och kursplaner.

Drömmen om Asien : en studie om hur svenskar prövar sina vingar på andra sidan jorden för en framtida karriär

Lindman, Petra, Reibring, Anna January 2014 (has links)
Denna uppsats presenterar ett relativt nytt identifierat fenomen – Self-Initiated Expatriate (SIE) – en subgrupp inom expatriering, ur ett svenskt perspektiv. Författarna har undersökt vilka möjligheter och utmaningar nyutexaminerade svenska SIEs möter när de söker anställning i en region de tidigare bedrivit utbytesstudier i, med fokus på Asien. Studien är begränsad att undersöka Hongkong som representant för världsdelen. För studiens utförande har författarna besökt Hongkong för insamling av reell information. Data har erhållits via intervjuer, företagsbesök och tidigare forskningsresultat inom ämnet expatriering och självinitierat utlandsarbete. Utifrån dessa har författarna konstruerat ett teoretiskt ramverk, vilket sammanställs i en modell för att identifiera och tydliggöra erhållna resultat. Resultaten påvisar att de möjligheter som föreligger en SIE är framförallt dess inneboende vilja att utmanas, motivation och kulturella anpassningsförmåga, medan utmaningar främst utgörs av brist på såväl operationell erfarenhet som professionellt nätverk. Avslutningsvis presenterar författarna förslag på vidare forskning inom fenomenet och förekommande implikationer för detta.

Vers une nouvelle méthode efficace et respectueuse de l'environnement pour la protection contre la corrosion des alliages de magnésium pour l'industrie aéronautique

Leleu, Samuel 06 April 2018 (has links) (PDF)
Les alliages de magnésium représentent une alternative à l’utilisation d’alliages d’aluminium ou de matériaux composites, en particulier dans le secteur aéronautique dans l’objectif de réduire la masse des structures. Ces travaux de thèse ont pour but de participer au développement de nouvelles méthodes de protection des alliages de magnésium, plus efficaces et respectueuses de l’environnement. Pour mener à bien ces travaux, des techniques électrochimiques, en particulier la spectroscopie d’impédance électrochimique, ont été couplées à des mesures par microscopie à force atomique (AFM), à des analyses par spectroscopie d’émission atomique à plasma induit (ICP-AES) et par spectroscopie de masse d’ions secondaires à temps de vol (Tof-SIMS) ainsi que des essais normalisés industriels. Tout d’abord, la résistance à la corrosion en milieu Na2SO4 de trois alliages de magnésium contenant des terres rares (WE43, EV31 et ZE41) a été étudiée et comparée à celle de deux alliages riches en aluminium (AZ31 et AZ91) et à celle du magnésium pur. Pour tous les alliages, il a été montré que les particules intermétalliques agissent comme des cathodes locales. Cet effet de couplage galvanique est plus marqué pour les particules riches en terres rares, en particulier dans le cas de l’alliage EV31. Conjointement, la corrosion est contrôlée par la dissolution de la matrice riche en magnésium et par le recouvrement progressif de la surface métallique par un film d’oxydes/hydroxydes. Ce film est plus protecteur pour les alliages que pour le magnésium pur mais cet effet bénéfique n’est toutefois pas suffisant pour compenser le rôle néfaste joué par les particules intermétalliques. Au final, l’ajout de terres rares augmente la vitesse de corrosion des alliages de magnésium en milieu Na2SO4 par rapport à celle des alliages AZ ou celle du magnésium pur. Dans le cas de l’alliage WE43, qui a été retenu pour la suite de l’étude, il a été montré que le film protecteur d’oxydes est plus mince et plus stable que celui formé sur le Mg pur, en particulier en présence d’ions chlorure. Ces résultats ont été expliqués par l’incorporation des éléments d’alliages, comme l’yttrium, qui serait responsable de la formation d’un film d’oxydes plus compact. Puis, plusieurs méthodes de protection ont été envisagées dans le but d’obtenir une résistance à la corrosion compatible avec les exigences de l’industrie aéronautique. Un traitement d’anodisation, développé par la société Prodem et appelé CEP, en combinaison avec plusieurs primaires de peinture sans chromate, proposés par la société Mapaéro (hydrodiluable ou haut-extrait sec) ont été évalués et comparés aux solutions de référence chromatées. Il a été montré que les traitements de conversion actuels, même en présence de primaire chromaté, ne permettent pas une protection efficace des alliages de magnésium. Le traitement CEP, de par sa structure poreuse, permet une bonne adhésion avec les primaires. Les meilleures performances ont été obtenues pour le traitement CEP revêtu par le primaire haut-extrait sec. Des analyses supplémentaires ont montré que l’ajout d’un vernis permettait d’obtenir un système de protection prometteur pour le remplacement des systèmes de référence sur la base des exigences clés aéronautiques.

CONSISTÊNCIA DAS INFORMAÇÕES ARQUIVÍSTICAS REFERENTES AO REGISTRO E ÀS ALTERAÇÕES DE PROJETOS NO SIE PATRIMÔNIO DOCUMENTAL DA UFSM / CONSISTENCY OF THE FILE INFORMATION RELATED TO THE REGISTER AND THE ALTERATION OF PROJECTS IN SIE DOCUMENTARY PATRIMONY OF UFSM

Viana, Gilberto Fladimar Rodrigues 05 May 2011 (has links)
The objective of this work is to analyze the present situation of the registers and alterations in the file information concern to projects from Arts and Letters Center CAL, of the Federal University of Santa Maria UFSM, which compose the databases of the institution. So that, file information related to projects, collected through the access to documents and written reports from the databases of UFSM were used. Also, a questionnaire, addressed to teachers from CAL, was applied. Based on the analysis of the surveys, written reports and the questionnaire some conclusions were reached. Through the description of the system of the register of the projects it was observed that the screen participants offer much information about this participation, reflecting in the academic life of teachers and students. Another result refers to the increase evolution in the number of projects registered since the beginning of the system working. In addition, it was verified, by applying the questionnaire to teachers, many situations like those related to titles and the implications involved in the register of the projects. The analysis of the declarations collected through interviews addressed to responsible people for SIE in the CPD and PROPLAN contribute to the diagnosis of the system, mainly focusing on the authenticity and reliability of the file information available. These evidences allow presenting, in the end of the work, some recommendations to SIE improvement. So, it will hope that the results obtained in this research can be considered referential as the UFSM as other institutions that have interest in this work. / Este trabalho tem por objetivo analisar a situação atual dos registros e alterações das informações arquivísticas, pertinentes aos projetos do Centro de Artes e Letras CAL, da Universidade Federal de Santa Maria UFSM, que fazem parte do banco de dados da instituição. Para tanto, foram utilizadas informações arquivísticas a respeito de projetos, obtidas através do acesso a documentos institucionais e de relatórios do banco de dados da UFSM. Também foi aplicado um questionário dirigido aos professores do CAL. A partir da análise dos levantamentos, dos relatórios e desse questionário, chegou-se a algumas conclusões. Pela descrição do sistema de registro de projetos, observou-se que a tela participantes traz várias informações referentes a essa participação, com repercussões na vida acadêmica de seus discentes e docentes. Outra constatação é a crescente evolução do número de registro de projetos ao longo do funcionamento do sistema. Verificou-se, ainda, através da aplicação do questionário aos docentes, várias situações como aquelas que estão relacionadas à titulação e às implicações que envolvem o registro de projetos. A análise dos depoimentos obtidos através de entrevistas dirigidas aos responsáveis pelo SIE no CPD e na PROPLAN contribuiu para o diagnóstico do sistema, principalmente sob o enfoque da autenticidade e da fidedignidade das informações arquivísticas por ele disponibilizadas. Essas constatações possibilitaram apresentar, ao final do trabalho, algumas recomendações para aprimoramento do SIE. Espera-se, portanto, que os resultados obtidos nesta pesquisa possam ser considerados como referencial, tanto para a UFSM, quanto para outras instituições que tenham interesse neste trabalho.

Reuse of construction materials : Environmental performance and assessment methodology

Roth, Liselott January 2005 (has links)
Reuse is a measure for resource-saving materials and energy use, which is stressed in the concept of kretsloppsanpassning, or societal industrial ecology (SIE), as it will be termed in this thesis. Reuse is here used as a general term for any kind of reuse and divided into recirculation, upgrading and cascading, according to the degradation of the inner material structure. Reuse of construction materials in society is mainly done with the belief that any kind of reuse is environmentally beneficial. However, this assumption is seldom critically assessed. The aim of this thesis was to examine under which conditions reuse of construction materials in the Swedish building and transportation sectors is beneficial to the environment. In order to identify critical conditions, the environmental performance of actual building projects that to a large extent utilised reused building materials was assessed (Papers V-VI). To better understand the practice of SIE and how it was implemented, the transportation sector was studied (Paper I). In order to address the issue of assessing the environmental performance of construction material reuse, method development became an important part of this thesis. Methods and tools employed in this thesis were required to be able to simultaneously address different system boundaries and also involve simplification. Studying the implementation of SIE revealed the lack of a holistic approach in environmental management, though it is present in the overall objectives of the SIE concept (Paper I). This was concluded by studying the energy and material stocks and flows in a life-cycle perspective in the environmental management of the Swedish National Rail and Road administrations. The study showed that the SIE-related measures implemented were outflow oriented, while the material inflows were generally quantified. Overall, the management and use phases were addressed, while the construction and deconstruction phases were poorly considered. Studying environmental assessment methods showed that an important characteristic is the system boundaries, which to a large extent decide which issues could be addressed and what actually could be studied (Paper II). Environmental assessment methods applied to reuse of construction materials were organised in an assessment framework of four system levels: the material level, the local environment level, the narrow life-cycle level and the industrial system level. It was concluded that mainstream environmental assessment of construction material reuse that is performed in the process of development consent and also in research, mainly addresses the narrow scope of the material level. In order to apply a holistic approach to environmental assessments of reuse of construction materials, the system boundaries needed to be widened. When selecting system boundaries, methods and indicators, researchers indirectly decide on which environmental pressures we consider the most important (cf. Papers II - III). There are trade-offs between making broad or deep environmental assessments. To accomplish an environmental assessment wide in its scope requires abundant resources and is complicated to carry through. Simplifications of the complex reality are always needed. However, to counteract the risk of problem shifting, the simplified methods and indicators need to be balanced for environmental relevance and used with knowledge of what they reflect and what is left out (Paper III). One example of such method simultaneously environmentally relevant and capable to cope with wide system boundaries is the study of primary energy use in a life cycle perspective, applied to a material an energy use context (see Papers IV-VI). In searching for a tool to prioritise building materials in building research and environmental management of the building sector, the total amount of building materials present in the Swedish building material stock was multiplied by their embodied energy coefficients (Paper IV). This product was normalized for the building materials’ service life. The accounting resulted in an ordering of building material categories according to their energy intensity. These are, in decreasing order: wood materials, bricks and other ceramics, concrete and steel. After calculating energy use in a life-cycle perspective for the recirculation, upgrading and cascading of larger building reuse projects of concrete and clay bricks, it is not self-evident that reuse is beneficial for the environment (Paper V, VI). It mainly depends on the use of auxiliary materials and their embodied energy, but also the primary energy use for the reuse processes, such as transportation distance and mode between the deconstruction and construction sites. In order to improve the environmental benefits of reuse, primarily the auxiliary materials used in current reuse projects should be minimised. Otherwise, there is a risk that the energy use for these materials turns reuse into an unfavourable process for the environment. Furthermore, reuse should preferably be environmentally assessed with a wide scope before implementation. What is included in such environmental assessment is significant for the outcome and the pictured environmental performance. / On the day of the public defence of the doctoral thesis the status of article III was: Accepted.

COUPLAGE SPECTRO-ÉLECTROCHIMIQUE RAMAN-IMPÉDANCE : APPLICATION À LA POLYANILINE

Wang, Xiaodong 04 February 2009 (has links) (PDF)
La spectroscopie électrochimique d'impédance (SEI) renseigne sur les mécanismes à l'interface électrode-électrolyte, mais ne peut pas identifier la nature des espèces adsorbées à la surface de l'électrode. La spectroscopie Raman est une technique puissante pour la recherche structurale ; elle peut fournir les informations requises au niveau moléculaire, qui sont absentes des mesures de SEI. Le but de ce travail a été de mettre au point la méthode de couplage dynamique de ces deux techniques. Cette nouvelle méthode -La spectro-électrochimie Raman-Impédance- a ensuite été appliquée à l'étude d'un film de polymère conducteur. Le principe de la méthode consiste à analyser le spectre émis par l'interface, et à convertir l'intensité des bandes choisies en une tension électrique. Plusieurs fonctions de transfert ΔV/ΔI, ΔRaman/ΔV, Δ Raman/ΔI ; sont enregistrées simultanément. Les premiers résultats de cette méthode appliquée à l'étude d'un film mince de polyaniline prouvent que l'équilibre acido-basique à l'intérieur du polymère doit être pris en considération sur la base d'un mécanisme cinétique impliquant deux réactions rédox et une réaction chimique.

Bewilderments of vision : hallucination and literature, 1880-1914

Tearle, Oliver M. January 2011 (has links)
Hallucination was always the ghost story's elephant in the room. Even before the vogue for psychical research and spiritualism began to influence writers at the end of the nineteenth century, tales of horror and the supernatural, of ghosts and demons, had been haunted by the possibility of some grand deception by the senses. Edgar Allan Poe's stories were full of mad narrators, conscience-stricken criminals and sinners, and protagonists who doubted their very eyes and ears. Writers such as Dickens and Le Fanu continued this idea of the cheat of the senses. But what is certainly true is that, towards the end of the century, hallucination took on a new force and significance in ghostly and horror fiction. Now, its presence was not the dominion of a handful of experimental thinkers but the province of popular authors writing very different kinds of stories. The approaches had become many and diverse, from Arthur Machen's ambivalent interest in occultism to Vernon Lee's passion for art and antiquity. Henry James's The Turn of the Screw (1898) is the most famous text to pose a question that was, in fact, being asked by many writers of the time: reality or delusion? Other writers, too, were forcing their readers to assess whether the ghostly had its origins in some supernatural phenomenon from beyond the grave, or from some deception within our own minds. This thesis explores the many factors which contributed to this rise in the interest in hallucination and visionary experience, during the period 1880-1914. From the time when psychical research became hugely popular, up until the First World War often considered a watershed in the history of the ghost story and literature in general something happened to the ghost story and related fiction. Through a close analysis of stories and novels written by Robert Louis Stevenson, Vernon Lee, Henry James, Arthur Machen, and Oliver Onions, I attempt to find out what happened, and even more importantly why it happened at all.
