Mjukvarukvalitet i öppen programvara - en explorativ och kvalitativ studie av uppfattningar om mjukvarukvalitet
Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.
Världen vill bedras... : Lärare och elever om källkritik
The aim with this study is to examine how students and teachers value source criticism. Partly, this regards how teachers practice this in their teaching and how students work with it during lessons ? but also how students value source criticism in situations where the teacher not has pointed out that this topic is part of the actual assignment. Moreover, there is a focus on investigating how students who are critical of the sources take this into account in their daily lives; for example, when they surf on the Internet or when they discuss news articles or other media. This essay is based on interviews with students and teachers, using a qualitative method. The results of this study show that both students and teachers find source criticism to be of major importance.
How do intrinsic and extrinsic motivation correlate with each other in open source software development?
Open source is growing outside the boundaries of hackers, amateurs and software development, creating a humongous potential in many different areas and aspects of society. The intrinsic and extrinsic motivations that drives open source have been in the subject of much research recently, but how they affect each other when paid and unpaid contributors come together is still hidden in obscurity. In this study I investigate how intrinsic and extrinsic motivation correlates with each other and how those correlations affect paid and unpaid open source software contributors. The literature synthesis is based on of systematic reviews through searches in library databases, identification of articles by searching on the Internet and by reading relevant books. My results indicate that intrinsic and extrinsic motivations continuously affect each other and that paid contributors are more vulnerable since their extrinsic motivation in terms of money is reached only when many other motivations are fulfilled.

Syftet med denna undersökning är att erhålla relevanta frågeställningar som ska utgöra engrund för att ge en rekommendation på en pedagogisk Open Source-programvara som stödjere-learning. En utvärderingsmodell skapas för att få fram ett relevant resultat baseras på svarenpå dessa frågeställningar. Utvärderingsmodellen tillämpas i en fallstudie för att visa enpraktisk användning av modellen. Det framgår vad som är relevant att tänka på vidinförskaffande av en Open Source-programvara som ska vara så pedagogisk som möjligt..
Optimisation of a method for isolation of Clostridium difficile from faeces
Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.
How do intrinsic and extrinsic motivation correlate with each other in open source software development?
Open source is growing outside the boundaries of hackers, amateurs and software
development, creating a humongous potential in many different areas and aspects
of society. The intrinsic and extrinsic motivations that drives open source
have been in the subject of much research recently, but how they affect each
other when paid and unpaid contributors come together is still hidden in
obscurity. In this study I investigate how intrinsic and extrinsic motivation
correlates with each other and how those correlations affect paid and unpaid
open source software contributors. The literature synthesis is based on of
systematic reviews through searches in library databases, identification of
articles by searching on the Internet and by reading relevant books. My results
indicate that intrinsic and extrinsic motivations continuously affect each
other and that paid contributors are more vulnerable since their extrinsic
motivation in terms of money is reached only when many other motivations are
fulfilled.

Undersökning av open source GIS programvaror : Med hänsyn till MSB?s användningsområden internt och för RIB Karta
MSB stands for Swedish Civil Contingencies Agency. It?s a government organization that deals with emergencies and crises. MSB has developed a software package where the newest software version is called RIB 2012. The package includes the program RIB Karta.
Fria och öppna programvaror inom kommunal verksamhet : Vägen mot öppna standarder?
This report deals with the attitudes within municipalities of open source software and open standards and if open source software may be an option to gain open standards. The aim has been to find out if open source software and open standards would be able to solve the lock-in problems that municipalities have against proprietary software. The study is conducted as an exploratory, inductive and qualitative study with depth interviews of subjectively selected informants as data collection method. A literature review has also been implemented by the relevant books and articles. Some economic determinants of municipalities to make use of open source software have not been considered in this study.
Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster
The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
Border Gateway Protocol : Implementationer på stubnätverk
Arbetet tar upp BGP-multihoming för mindre organisationer. Den jämför ett kommersiell alternativ mot open source-alternativ. Detta är för att se vad som krävs en av open source-lösning för ge konkurrens på routermarknaden, samt besparingar för organisationer som ska använda denna lösning.Praktiska och teoretiska jämförelser görs där Cisco-lösningar jämförs med OpenBGPD. Datan utifrån dessa tester används för att svara på problemfrågan. Sammanfattningsvis har open source produkter en fördel hårdvarumässigt på grund av lägre kostnader medan kommersiella har stora fördelar då de förlitar sig på nyare standarder..
När kritiska elever är målet. Att undervisa i källkritik på gymnasiet
This essay examines teaching in source criticism in upper secondary school history education. Two questions are to be answered: 1. What are the conditions like for teaching source criticism? 2. What opportunities for further development in teaching source criticism are there? In order to set a standard for what knowledge and skills in source criticism the students need, I design a four step model for good source criticism based on the historical science.
Informationssökning i elektroniska informationskällor Valmöjligheternas vånda
The purpose of this thesis is to examine which factors influence librarians selection of electronic information sources, and to investigate whether librarians use of search strategies and search tactics changes depending on which information source they use. The electronic information sources are: online databases, Online Public Access Catalogues OPAC, World Wide Web, and CD-ROM databases. The theoretical framework is based on step 3 Select a source and step 4 Formulate a Query in Marchioninis information seeking model. The search strategies are divided into two categories: analytical and browsing strategies. In order to supplement the theoretical framework with empirical facts, 8 librarians were interviewed.
Vattenskydd och krisberedskap hos allmän dricksvattenproduktion : Skydd av täkter, tillgång till reservvattentäkter och andra nödvattenlösningar hos svenska vattenproducenter
The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking water production, in case the commonly used water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their water sources and for many sources the protection was not satisfactory.
Magnetiska egenskaper hos Öje-Diabasen, Dalecarlia
A study of paleomagnetic remanence and anisotropy of magnetic
susceptibility (AMS) has been performed on the Öje-Diabase
in Dalarna, Sweden, and on basic dikes associated with the
alkaliquartzsyenite/granite Noran-pluton in central Sweden.
Based on isolation of directions of characteristic magnetization
in the basic rocks, a division into three different groups (A,B,C)
has been made. Group Aconsists of dolerites of Jotnian origin,
both dolerites from the Öje-Diabase and dikes associated with
the Noran-pluton are included in this group, making them coeval.
Group B is suspected to show a re-magnetization from the later part
of the Svekonorwegian orogeny. Group C belongs to the
Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of
dolerites revealed two different types of demagnetization behaviours,
one where magnetite clearly was the source of the remanence, and an
other with a linear decrease in magnetization intensity. The measurements
of magnetic anisotropy reveals a magnetic fabric with an almost
horizontal foliation and a lineation that indicates a fairly uniform NNW/
S-SE flow direction of the magma..
