Words like pirates and anti-pirates are becoming common features in the cultural political debate of today, and the file-sharing phenomenon has become a more and more delicate and disputed subject. The fact that people are organizing in networks to swap computerfiles with each other has, among other things, led film and music companies from all over the world to initiate a number of anti-piracy organizations, assigned to protect the right to culture and information. The industrial organization Antipiratbyrån (the Anti-pirate Bureau) and the network Piratbyrån (the Pirate Bureau) have on several occasions been used to represent the prevailing conflict in Sweden. The purpose of this study is to apply a sociological perspective to the collective act of file sharing. Additionally, the purpose is to argue that the activity can be understood as a social movement, although it is rarely referred to as such.

Songs from the Crypt: Mapping the Forces that Hinder the Digital Revolution of Music Distribution This paper seeks an explanation to the low market share growth of the commercial digital music distribution in Sweden. The analysis identifies a spectrum of obstacles that hinder the digital distribution technology from becoming the main form of music distribution in Sweden. These obstacles make the digital music distribution less favourable in comparison with physical distribution from the consumer?s point of view. The authors suggest that in order for the digital distribution of music to become competitive the digital product would either have to be developed further to offer more customer value or the so called a là carte retail model would have to be replaced by a subscription-based distribution model.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

The aim of this study was to comprehend and explain the idea and function of Case Management and its diffusion in Swedish municipalities. More specifically its aim was to investigate factors for the diffusion of Case Management and its differences to similar professional roles. The study was based on interviews with four managers at various levels and two case managers representing two municipalities in Sweden. Five themes were identified that were especially interesting when discussing the function of Case Management, its differences to similar professional roles and its diffusion in Swedish municipalities. The themes were: shortcomings in the welfare system, the functions of Case Management, differences to similar professional roles, descriptions of Case Management and factors for the diffusion.

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

The purpose of this thesis is to examine a new music downloading service called Musikwebben, which is now available in many Swedish libraries. It focuses on the differences and similarities between this service and illegal music sharing services. The question is raised, whether the appeal of Musikwebben is high enough for it to be able to ?recruit? users from similar, illegal services. To answer this question, a qualitative content analysis is used, to explore various views on what legal downloading services have to offer and how these differ to illegal alternatives.

Denna rapport undersöker krav, tagna från ett ramverk för evaluering av CASE-verktyg i ett kontextuellt sammanhang, i två representativa CASE-verktyg. Ramverket utnyttjar en modell som föreslagits av Lundell och Lings för att extrahera både krav och förväntningar som en organisation (www.it.volvo.com) hade på vad ett CASE-verktyg är och kan utföra.Ramverket extraherar krav i ett organisationell kontext, dvs. utvärderingen utfördes innan verktyget som evaluerades användes i organisationen. Detta indikerar på att kraven inte är knutna till ett specifikt verktyg, samt att CASE-verktyg inte säkert stödjer dessa krav.Resultatet för denna rapport är att viss semantisk förlust uppstod vid transformering av kod och modeller..

The purpose of this study was to find out why the law that regulates downloading copyrighted material does not work and which of the most important main reasons lies behind downloading behaviour. The phenomenon being well investigated earlier has actualized a new demand for normative investigation in connection with the hot debated IPRED-law.Using qualitative method comprising of interviews with three typical file sharers and anchored in Max Webers action typology, rational choice theory and the norm model followed by two assessment models, we found that four important reasons lies behind downloading behaviour: 1) economical reasons was the most central and frequent determinant followed by 2) accessibility and comfort, and 3) social acceptance and moral and also 4) habits. Although the content of the law was correctly provided by the interviewees, it was clear that they did not perceive the impact of the law as meaningful or threatening.The results, being compatible with previous research, are discussed in terms of the named theories and assessment models. We suggest further research to take into account peoples norms as the new IPRED-law soon will be functional as well as studies from a perspective of the legal rights of the individual..

The purpose of our study is to examine the case managers reasoning and descriptions of empowerment as a method in their social work from a comprehensively perspective including family members. To manage with this purpose we interviewed two case managers, two clients with mental disabilities and five family members. We have come to the conclusion that the case managers works more consist of advocacy than empowerment. Despite that we have found that the long term goal for the case mangers work is to give the clients tools for empowerment. Our results also show that the clients feel that they have gained and increased their ability to do things by themselves and to be a part of the community.

The purpose of this thesis is to compare mass digitization and qualitative digitization, to see how the digitization process and the digitalized material differ. The study emanates from the mass digitization as it is performed at the National Library in Norway, and the qualitative digitization at the Royal Library in Sweden. The method used is document studies combined with mail interviews. The focus is upon the practical operation, to which counts: ?purpose & selection?, ?preparation, image capturing and processing?, ?metadata & text encoding?, ?quality assessment?, ?storage of digital originals and copies? and ?display?.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

Detta examensarbete ger en introduktion till området systemutveckling. Kravhantering har i alla tider varit en viktig del i systemutveckling. För att kunna lyckas med kravhanteringen under ett systemutvecklingsprojekt är det viktigt att använda sig av rätt teknik. En teknik som finns för att kunna hantera de krav som ställs på ett system är Use Case som härstammar från UML. Syftet med detta examensarbete var att ta reda på de för och nackdelar som har upplevts av användare som har arbetat med Use Case i samband med kravhantering.

Ett effektivt användande av ett informationssystem förbättrar informationshanteringen inom en verksamhet. För att ett informationssystem ska kunna fungera effektivt krävs att det motsvarar de krav som ställts på informationssystemet av olika intressenter.Requirements Engineering (RE) är en viktig del av systemutvecklingsprocessen för att kunna säkerställa en väl fungerande kravhantering. Use case är en teknik som kan användas som hjälpmedel i RE-processen för att identifiera och dokumentera krav.Syftet med detta examensarbete är att undersöka om use case är tillräcklig som enda teknik för att identifiera och dokumentera krav samt vilka eventuella kompletterande tekniker som används bland systemutvecklare. Resultatet av undersökningen visar att use case-tekniken inte är tillräcklig utan måste kompletteras med andra tekniker för att möjliggöra att samtliga krav kan identifieras och dokumenteras..
