This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.

I Sverige och utomlands har man på senare tid sett framväxten av ett nätverk av s.k. Science Centers (SC). Dessa SC har som viktigaste syfte att öka besökarnas naturvetenskapliga intresse. När det gäller elever från högstadiets senare år kan detta ökade intresse för naturvetenskap t ex visa sig i form av en ökad benägenhet hos eleverna att söka sig till ett naturvetenskapligt inriktat gymnasieprogram.Vi har utvecklat och använt en enkät-baserad metod för att undersöka den påverkan på elevers intresse för naturvetenskap som ett besök på SC har. Enkäten är lämplig att användas för elever från grundskolans senare årskurser.

In today's social work there is an ambition to work evidence-based in order to improve quality and competency in business. This study is made in a disability administration which has introduced a common approach towards users for all employees. The approach is called low arousal approach. The purpose of the study is to investigate how a method takes hold and implements within an organization. The empirical data is analyzed by theories of professionalization, idea dissemination and translation.

Technological advancements in information and communication technologies (ICT) have resulted ina need to use ICT in schools. Sweden has actively promoted ICT in schools since the early 1980's.In Japan, 1994 saw the government's first step towards active promotion of ICT in education. In thisstudy, we have compared the strategies used to promote the use of ICT in elementary and secondaryschools in Sweden and Japan. Our findings suggest that a similar 3-step approach was used in bothcountries: 1, infrastructure; 2, effective use of ICT; 3, implementation of ICT. A significantdifference was found in the way the two countries planned their strategies.

Detta examensarbete behandlar affärssystem (även kallade ERP-system) och implementering av dessa. ERP betyder Enterprise Resource Planning och innebär ett integrerat system som innefattar hela företagets verksamhet.Att införa ett affärssystem i en organisation är en stor investering och ofta en komplicerad uppgift, det är därför bra om tidigare erfarenheter från liknande implementationer kan utnyttjas. I mitt arbete har jag undersökt vilka faktorer en organisation bör beakta för att erhålla en lyckad implementering. Arbetet har bedrivits i form av en fallstudie där jag genom intervjuer med projektdeltagare har studerat den implementation som Volvo Lastvagnar Komponenter AB i Skövde nyligen har genomfört av affärssystemet SAP R/3.Resultatet av undersökningen kan sammanfattas i tre övergripande områden; planering, utbildning och resurser. Dessa områden är alla viktiga att beakta i samband med en implementering av ett affärssystem för att implementeringen skall nå ett, för företaget, lyckat resultat..

AbstractOur purpose for making this study is to study the implementation, the use of and the effects of Lean within our case objects.  We chose to make this thesis by case studies. The three themes mentioned above is also the main research questions that we aim to find an answer to by this study. We have chosen to do a cross section analysis where we conducted structured interviews to find answers to these questions. The theoretical reference frame consists partly of traditional theoreticians within Lean but also more recent research within the subject as well as theory specifically for Lean within the Health Care sector.The result of this study shows in all our case studies that the Management has been supporting the implementation, but that the implementation process proceeds faster if also the professionals are involved in the process.  To succeed with the implementation there is a great need for good reasons and strives that can benefit the professionals. By the use of Lean our case studies have evaluated its processes, with the main intentions being to reduce waste activities and to create flows with ?pull systems?.

The purpose of this paper was to investigate what young behavioral science students, born in the 1980s, think is important in their future work life. The purpose has also been to investigate what attitudes the behavioral science students have towards their future work life, and what place work has in the young behavioral science students lives. After clarification of above, the aim has also been to compare the results with former research. Thereafter the purpose has been to investigate whether traditional work motivation and job satisfaction theories are applicable for young people today. The empirical material is based on interviews with six women who study behavioral science at various levels.

Detta examensarbete utfördes hos företaget Syntronic i mjärdevi. Uppgiften de ville ha utförd var en undersökning och implementation av ny funktionalitet i en redan existerande android applikation som de har utvecklat. Uppgiften i denna applikation var att undersöka möjligheterna till IP-telefoni, eller VOIP som det kallas, så att de kunde ringa varandra via applikationen genom datanätet istället för det ordinära nätet, samt att implementera detta.Detta examensarbete utfördes hos företaget Syntronic i mjärdevi.

The thesis of this essay is that the concept of governance is a product of the neo-liberal dominant ideology and that the implementation of governance ideas will lead to a weaker nation-state. Using critical theory the essay constructs an ideal type of neo-liberalism and compares its core values with these of the governance concept as treated by the main literature in the area. The essay then focuses on the issue of the state, and discusses whether the changes leading to a demand for governance have actually weakened the state. Furthermore, the essay presents the practical use of the term governance in the EU and Sweden and problemizes the changes that the neo-liberal domination has led to in terms of power and democracy. Finally the essay discusses alternative views on the changing role of the state.

Då mängden information bara ökar, så ökar även behovet att ha åtkomst till informationen lättillgängligt. Detta skapar då ett behov för ett gränssnitt som kan söka bland informationen. I detta arbete har det undersökts om en implementation av Vector Space Model ger mera relevanta resultat jämfört mot en enklare implementation som inte baseras på Vector Space Model. Sökningen utförs i en relationsdatabas med ett inverterat index, databasen fylls med data ifrån internetforumet Stack Overflow. Genom att bygga en sökmotor som returnerade två olika resultatlistor för varje sökning så fick tio användare testa och utvärdera resultatens relevans.

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.

Av dagens affärssystem krävs det att spårbarheten är större och mer pålitlig än tidigare. På grund av att affärssystem blir allt vanligare, infinner sig på fler marknader och kan i vissa fall vara kärnan i ett företag är detta ett krav. Examensarbetet är utfört på Infor i Linköping som tillhandahåller affärssystemet M3. Efter Enron-skandalen skapades flertalet regleringar och lagar som företag måste anpassa sig efter. Vi har undersökt vad som krävs för att tillmötesgå dessa krav och försökt hitta en minsta gemensam nämnare för flertalet lagar och myndigheter.
