Skönlitteraturens nya kläder? Elektronisk publicering av skönlitteratur: en kvalitativ intervjustudie med nio svenska förlag och fyra andra aktörer på det litterära fältet

The main objective of this essay is to present the views of nine Swedish publishers and four other agents in the literary field regarding the possibilities of and obstacles to publishing fiction in an electronic format. Furthermore, whether or not electronic publishing is today actually a viable alternative. A substantial part of the essay functions as background to our interview findings and is based primarily on material originating from the Sociology of Literature field. The introductory chapter expounds the methodological and theoretical basis of the essay and is followed by a chapter placing our study in a larger, international media, context. Chapter three deals with the past decades? restructuring of the publishing sector, the professional functions involved in traditional publishing and Pierre Bourdieu?s theories on the cultural and economic forces at work in the literary field.

Bakhjulsupphängning, fyrhjuling

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

Gruppdynamik : en social gemenskap

The purpose of this work is to create more knowledge about the teacher's perceptions of group dynamics and its impact on school activities. How do teachers opportunities and obstacles in order to influence group dynamics among students. The questions I have answered is how the teachers see the importance of a functioning group dynamics in school, how teachers work with group dynamics and how teachers describe the opportunities and obstacles for effective group dynamics. The method I am using at work is a qualitative research method that involves obtaining the teachers' own thoughts, feelings and experiences around the right questions. I have interviewed three teachers in primary schools in the county of Stockholm to find out their particular approach.

Utvecklingen av röstigenkänningsprogram under en treårsperiod

Detta kandidatarbete är utarbetat på Blekinge Tekniska Högskola under våren 2002. I utredningen har vi jämfört röstigenkänningsprogram under en treårsperiod, program från 1999 och program från 2002. 1999 års test visade på programvaror med lång träningstid, enkla gränssnitt, stor känslighet för bakgrundsljud och låg användbarhet. Vid arbetsstart förväntade vi oss inte att hitta någon större förändring i användbarheten hos dessa program 2002, då röstigenkänningsprogram inte verkar ha stor användarskara. Utifrån följande hypotes har vi genomfört arbetet: Vi vill med vår undersökning bevisa att användbarheten inom röstigenkänningsteknologi inte har förbättrats under perioden 1999-2002. Vi har för avsikt att med hjälp av test utförda på program och demoversioner bevisa vår hypotes. I enighet med bifogad testspecifikation har vi utfört testerna. Många företag har utvecklat sina produkter och gjort dem bättre.

Informationsteknik och högskolan ? policy och verklighet

The main objective of this thesis is to examine the situation concerning information technology, computers and information resources for university students at a selection of universities, and their libraries, in Sweden. Another objective is to compare this situation to what is stated in policy documents on the subject, and if the size of the university matters regarding resources. The thesis starts with a discussion of several authors, Frank Webster, Paul F. Burton and Lars Qvortrup among others, and their views on the information society. These range from whether we are living in it, are in a transition period or are still in the Industrial Society.

När EU togs till folkhemsförsvaret - Översättningen av europeiska normer till Försvarsmakten

The Swedish Armed Forces have gone through a remarkable change. From beingan organisation built on the notion of countering a Soviet invasion it has evolvedto focusing on small, multilateral rapid reaction capabilities to be used within theframework of the European security and defence policy, ESDP.This thesis regards the change as a process of Europeanisation. Drawing fromsociological and historical institutionalism, it is shown that the Swedish ArmedForces in the post-cold war context was path dependent and unwilling to redefineits historical raison d?être. The origin of the ESDP Europeanised the nationaldefence policy, whereas the bureaucracy was still unwilling to translate the newstructural norms.

Funktionella krav på metadata: En undersökning av Dublin Cores överensstämmelse med FRBR

The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.

En Kommunikations Illustration : Interaktionen mellan deltagare i ledarlösa samarbeten

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

Förbättringsarbete på monteringsbana

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

Utvärdering av lösningar för hårddiskkryptering

Information stored on unprotected computers that gets lost or stolen, and falls intothe wrong hands, can easily be accessed by moving the hard disk to a controlledcomputer, or by booting the computer from a removable medium, in order to getaround the operating system login. This is something that largely affects companieswhere customer information, trade secrets and other sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected.

Uppleva eller leva upp till? : En studie om hur gymnasieelever upplever prestationskrav i idrott och hälsa.

AimThe purpose of the study was to investigate how upper secondary school students experience performance demands during their physical education and health classes (PE-classes). The questions were as following: Are there differing perceptions between the sexes whether students experience performance demands? In what situations do the students feel that the demands on their performance are high during PE-classes? Do the students experience of demands on performance differ whether the physical education and health teacher is male or female? Do students feel unfairly treated by the physical education and health teacher during PE-classes?MethodSeven upper secondary schools in Stockholm?s administrative district were randomly selected to participate in the survey. The principals were contacted for further information and to set a date for performing the survey. The project leaders were present during the days the surveys were taken by students in the social science and natural science programs.

E-förvaltningens roll i främjandet av demokrati. En fallstudie om offentlig förvaltnings relation till demokrati med stöd av IT

Information technology (IT) with its enormous capacity involves more and more in our daily activities and public sector is using IT to make their activities more efficient. The government goal with electronic government (e-government) among other things is increasing the availability and service to the public as well as improving the democratic process. Democracy can be strengthened by involving citizens in public decision making process but this goal has not been achieved yet and the development of e-government has mostly been focused on improving efficiency within administration and electronic services (e-services). Promoting the democratic process has been postponed in the development of e-government because of the lack of political commitment and decision. Digital divide is also preventing public sector to promote democracy with the support of IT.
