Femton svenskars skäl till att de slutat rösta på de politiska partierna

Dag, Simon January 2020 (has links)
Mindre än hälften av svenska väljare uppger att de har stort förtroende för politiker. Kvantitativa data har legat till grund för tidigare forskning som sett samband mellan politikerförtroende och en mängd demografiska variabler. Kvalitativa studier inom ämnet saknas. Syftet med denna studie var att undersöka skäl till att deltagare som haft förtroende för politiker tappat förtroendet i den utsträckningen att de inte röstat alternativt röstat blankt i 2018 års riksdagsval. Totalt intervjuades 9 män och 6 kvinnor med varierande ålder (25-63) och utbildningsnivå. Materialet analyserades tematiskt och följande teman identifierades: Politiker har låg trovärdighet, Missnöjd med systemet, Saknar partiidentifikation och En oacceptabel nivå. Deltagare gav ofta specifika exempel på situationer som lett till tappat politikerförtroende. Förtroende har åtminstone delvis tappats då deltagare inte anser att politiker är ärliga och att politiker inte lever upp till deltagarnas förväntningar. Fortsatta studier inom området rekommenderas för att ge en helhetsbild över tappat politikerförtroende.

Desenvolvimento e implementação de metodologia de otimização da geometria do blank em processos de conformação de chapas metálicas. / Development and implementation of a blank shape optimization methodology in sheet metal forming processes.

Moreno, Mariano Eduardo 25 May 2000 (has links)
Os processos de conformação de metais, apesar de sua extensa aplicação na indústria, tem seus projetos baseados principalmente em técnicas experimentais. Com o desenvolvimento e facilidade de acesso a computadores mais potentes, tornou-se viável a utilização de soluções numéricas como ferramentas de otimização das características do produto, do processo, bem como de seu custo. Um método numérico amplamente utilizado para simulação do processo de conformação é o Método dos Elementos Finitos, que permite a previsão do comportamento do fluxo de material durante a operação de conformação de chapas. Considera-se um blank com perfil ideal aquele onde a peça produzida a partir de sua conformação possua uma flange constante, minimizando ou eliminando a operação de retirada da rebarba. Com o objetivo de se obter o blank com perfil ideal para operação de conformação de chapas, desenvolveu-se uma metodologia de otimização geométrica da forma do blank, que trabalha integrada a um software comercial de análise pelo Método dos Elementos Finitos, o ANSYS/LS-Dyna3D. Apresentam-se os resultados aplicados à simulação da estampagem de uma peça prismática de base quadrada, como meio de validação da metodologia de otimização proposta. / The metal forming processes have extensive industrial application although their projects are based mainly in experimental techniques. With the development of more powerful computers, the use of numerical methods to design, simulate and optimize costs of such processes has become possible. Among the numerical methods, the Finite Element Method have large application in forming simulation, since it allows the prediction of the material flow during the sheet metal forming process. Ideal blank shape is that one which produces a part with constant flange, minimizing or eliminating trimming operations. In order to determine the ideal blank shape, this work developed a methodology to blank shape optimization. This optimization methodology has been integrated to a commercial Finite Element analysis software, the ANSYS/LS-Dyna3D. The results applied to a simulation of a square cup part are showed and discussed in order to validate the proposed optimization methodology.

The Role of Theodore Blank and the Amt Blank in Post-World War II West German Rearmament

Lowry, Montecue J., 1930- 05 1900 (has links)
During World War II, the Allies not only defeated Germany; they destroyed the German army and warmaking capability. Five years after the surrender, Theodor Blank received the responsibility for planning the rearmament of West Germany starting from nothing. Although Konrad Adenauer was the driving force behind rearmament, Theodor Blank was the instrument who pushed it through Allied negotiations and parliamentary acceptance. Heretofore, Blank's role has been told only in part; new materials and the ability now to see events in a clearer perspective warrant a new study of Blank's role in the German rearmament process. Sources for this dissertation include: Documents on Foreign Relations of the United States; memoirs, among them those of Konrad Adenauer, Georges Bidault, Lucius Clay, Dwight D. Eisenhower, Anthony Eden, Ivone Kirkpatrick, Harold MacMillan, Kirill Meretskov, Jules Moch, Sergei Shternenko, Hans Speidel, Harry S. Truman, Alexander Vasilevsky, and Georgiy Zhukov; contemporary reports from newspapers, among them the Times (London), New York Times, Le Monde, Pravda, Frankfurter Algemeine Zeitung, Suddeutsche Zeitung, and Das Parlement; Parliamentary Debates; official records; and interviews. Rearmament involved the interrelationship of vast, diverse interests: the conflict between East and West, national and international fears, domestic problems, and the interplay of leading personalities. When the Amt Blank, the planning organization, became functional on 1 December 1950, it consisted of nineteen people; in 1955, when it became the Defense Ministry with Theodor Blank the Defense Minister, it had a staff of one thousand. Cast in the milieu of the Allied negotiations on West German rearmament, this dissertation chronologically focuses on the role that Blank and the Amt Blank personnel played in the planning, negotiations, and domestic issues related to rearmament. Blank's diplomatic skills and managerial ability were key factors in transforming West Germany from a conquered area to a sovereign state, a member of NATO with approval for its own armed force, within a five-year period.

Směnka v současné praxi se zvláštním zaměřením na druhy a přípustnost kauzálních námitek a rozhodování o nich / Bills of exchange in the recent practice with special regard to types and admissibility of causal objections and relating decision-making

Švarc, Jan January 2011 (has links)
in English The thesis aims especially on questions concerning law of exchange which are not satisfactorily answered yet neither by academical community nor by judicial decisions made by the Czech courts and those which should be, from the point of my view, answered differently. In the first chapter, I tried to critically review various doctrinal definitions of bill of exchange and to draw up my own definition which affects bill of exchange complexly in its entireness. Second chapter is divided into three subdivisions chronologically. First subdivision refers to proofs of ancient documents congenial to contemporary bills of exchange. I have come to conclusion that the existence of bills of exchange can be proven as far as the beginning of the first millenium. Institute simmilar to the one of bill of exchange may be found in the Roman civil law. The second subdivision of second chapter assays medieval bills of exchange very thoroughly more than any other thesis on the same subject. All my ideas given are supported by quotations. The third subdivision briefly explains development of law of exchange in the modern period. The third chapter is dedicated to the general purpose of law of exchange and its modern usage with extra amount of attention paid to blank bills of exchange and collateral drafts....

My Trip to Notan

Chapman, James M 08 April 2012 (has links)
My Trip to Notan charts my own journey from the rawness and acceptance of multiple life losses into understanding, and finally, renewal. The key result of this project is a prototype book, a 48-page digital Print-On-Demand (POD) publication, which also includes a DVD that inserts into book’s back and features live demonstrations, interviews and other segments related to the book. Additionally, the body of work from which the book was gleaned was presented at the thesis exhibition. Ultimately, My Trip to Notan is a sketch of my understanding of the framework that threads through design, physics and philosophy, inspired by the simplicity of the ancient art of Notan, and upon my own fragmentary observations gathered from the journey. My hope was to reveal some sense of the pulse that drives the inquiry, rather than the suggestion of any sort of destination.
