Vinculo Vivo : José María Arguedas, Miguel Angel Asturias och Paulo Coelho

The principal questions that are high lightened in this study are: How is the discrimination of the Indigenous people in Latin-America represented in the works of Jose María Arguedas and Miguel Angel Asturias? How are these two authors interrelated in terms of the defense of a cultural belonging? And finally, can these be associated to Paulo Coelho?s narrative content and techniques?This work shows how, as Nelson Gonzalez-Ortega names it, a narrative discourse of resistance (based on the consequences of the cultural merging of the European and Latin-American people) is expressed and transformed into modern literature. It shows how the works of these authors protect and transmit the interests and the cultural origins of the Latin-American Indigenous people. These origins are expressed by language, myths, storytelling techniques and the presentation of an alternative perspective of the world. It also shows, through analysis of their writing, how some of these authors as dual cultural human beings struggled to balance the two cultural elements they are constituted of.Focus will be on Asturias Hombrez de Maiz, Arguedas Los ríos profundos and Coelhos 11 minutos and El Zahir..

Datorspel = Lärande? : En kvalitativ studie angående gymnasieelevers attityder gällande datorspel som läromedel

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

Konstruktion av säkerhetslagerför svänghjul

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Utvärdering av metoder och modeller för att simulera växlingskomfort i entreprenadfordon

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

UML som stöd vid småskalig utveckling av ett inbyggt system

This project aims at investigating if the use of UML as a support to small-scale development ofan embedded system is relevant. The investigation is conducted by using UML during the initialphase of the development ofTelfafill, a filling machine by the company ?Telfafill AB?. The aimof the development of Telfafill is to separate the user interface from the control unit. In additionto this main objective, Telfafill AB would like possible changes to, and additions of,functionality of the filling machine to be investigated.Within the boundaries of this project, the development of Telfafill reached a full requirementspecification of the proposed system, and contact was made with potential external developers.No prototype construction had been started when the project ended.

Folkmusik på tvären - En studie av spelteknik på den åttaklaffiga traversflöjten i irländsk och bretonsk folkmusik

Title: Playing techniques of the eight-keyed traverso in Irish and Breton traditional music. The dissertation examines basic aspects of playing techniques of the eight-keyed traverso, as it is used in Irish and Breton traditional music. The background material consists of four interviews with four professional flute players as well as literature that considers the subject from different perspectives. The results reveals a consensus between those of the informants that are mainly playing Irish music while the informant that is mainly playing Breton music has a different approach to several of the technical aspects examined.Examensarbetet behandlar grundläggande spelteknik på åttaklaffig traversflöjt inom bretonsk och irländsk folkmusik. Studiens underlag består av intervjuer med fyra professionella flöjtister samt av litteratur som belyser ämnet från olika perspektiv.

Förhandlingslösning som alternativ till fortsatt militär kamp : en studie av två irreguljära parters val

The Swedish Armed Forces tend to ask themselves if it is sufficiently multinational interoperablefor participation in international operations. An equally valid question today should be whether theSwedish Armed Forces are sufficiently nationally / internally interoperable, between their branchesof service, to be able to conduct independent operations based on the joint warfare theory.The lack of ability to joint warfare in the armed forces in general and the Swedish Armed Forcesspecially constitutes the essay´s fundamental problem. By using Codners and Sjöbloms custominteroperability theory, the Swedish Armed Forces documents were analyzed to highlight anyweaknesses related to joint warfare and national interoperability between Ground and Air Forces.The survey shows weaknesses linked to the custom theory and Swedish Armed Forces governingdocuments. The ability of a national interoperability is limited between Ground and Air Forcestoday, mostly because of weaknesses in the Swedish Armed Forces strategic concept which doesnot describe the importance of joint warfare at all levels sufficiently. This leads to deficienciesreflected in doctrines, regulations, technology, techniques and exercises.

Value at Risk : En jämförelse mellan VaR-metoder

Bakgrund: I och med att Basel II har instiftats i Sverige så måste finansiella institutioner beräkna sin marknadsrisk på sina portföljer. Detta kan göras genom olika VaR metoder. Dessa ger dock olika uppskattningar på marknadsrisken. De finansiella instituten får använda sig av den metod som de anser reflektera marknadsrisken bäst. Det finns dock ingen metod som utsetts till standard.Syfte: Syftet med detta arbete är att jämföra olika VaR-metoders skattning av marknadsrisken utifrån verkligt utfall, för att urskilja vilken metod som är funktionsdugligast.Avgränsningar: Denna undersökning inkluderar fyra olika VaR metoder.

Brands Transfer of Meaning: An analysis of brands roles within product placement

Thesis purpose: The purpose of this thesis is to make a contribution, by connecting the transfer of meaning within the context of TV series. The meaning is transferred from the brand to the character in a TV series and then further to the viewer. To look at different role functions that are used in dramaturgy and narrative techniques, we will be able to see how the brand will have a specific role and thereby make the transfer of meaning more successful and effective. This role will have an important impact on product placement according to the meaning that will be transferred from the brand to the viewer, through the character. Methodology: By looking at the transfer of meaning process that is created from the brand, an unstructured observation is applied where we observed the placement and usage of different within a specific TV series. Qualitative strategy is conducted by using a case study.
