Hur upplever gymnasieelever sin informationssökning? En studie på en skola utan tillgång till skolbibliotek

This masters thesis aims to investigate how upper secondary school pupils experience their information seeking in a school context without access to a school library. It is the pupils own thoughts and opinions about information seeking and criticism of the sources that is the main focus. The literature that has been used consists of material from research concerning youth and different aspects of information seeking such as the information seeking process, information seeking on the web, criticism of the sources and how pupils interact with other people in order to acquire information. The method that has been used is group interviews. Twelve pupils from an independent school without access to a school library have been interviewed in groups of three.

Metod för systemutveckling till småföretag

Systemutvecklingsmetoder har funnits för att utveckla system ochprogramvaror sedan vattenfallsmodellen gjorde sin introduktion på dentiden då IT kallades för data processning. Sedan dess har det funnits ettantal metoder, vissa av dem används än idag. Gemensamt för de flestametoderna är att de är anpassade till mycket komplexa system som användsinom stora organisationer. Inom det Svenska samhället så fanns det år 2005över 890 000 småföretag (0-49 anställda) enligt statistiska centralbyrån.Det är lätt att förstå att småföretagen är viktiga för Sverige. För att Sverigessmåföretag skall kunna överleva i en allt tuffare konkurrenssituation så ärdet viktigt att de hela tiden effektiviserar sina verksamhetsprocesser medexempelvis innovativa IT lösningar.

Hit och tillbaka : En studie om vägvisning på evenemang med fokus på Siestafestivalen.

Back and forth is a study on wayshowing at events focusing on the Siesta festivalin Hässleholm. For several years the interest in festivals has increased, whichhas contribute to expansion among festivals. The Siesta festival in Hässleholm istoday one of the major festivals in Sweden, attracting 10 000 visitors each year.The festival?s strong expansion has contributed to disorientation in the festivalarea, because it has never been constant from year to year. A side effect of this isthat the orientation is a constant problem.Therefore this study aims to investigate how a clearer route guidance systems onthe Siesta Festival can be designed based on existing designprinciples onguidance and orientation and how the information can be accessable towheelchair users and those with some kind of colourblindness?Surveys among festival visitors and interviews with the festival organizers for thefestival showed which navigation strategies that are most used on festivals.

Kan D-vitamintillskott minska depressiva symtom?

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

Utvärdering av Jönköpings kommuns beslutsstödssystem QlikView

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

Intranät - en kunskapskälla i arbetet?

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

Kunskapssamhället och skolan - vilken framtid möter våra lärare, elever och bibliotekarier?

The essay concerns "the knowledge society", IT and the possibilities of school being changedto meet the future. The purpose was to reflect the ideas of researchers and authorities concerningwork and education in "the knowledge society" and to illuminate/shed light on theimportance of information technology in this connection, to map organizational and pedagogicalshortcomings in the current school system and the changes that can be needed, and to investigatehow these changes can affect teachers, pupils and librarians.The investigation, which was a text analysis of normative and futurist sources, was especiallydirected towards how modem information technology can influence education/teaching.The differences between researchers and authorities were most obvious in the view of theimportance of knowledge of facts and central control mechanisms for standards or grading.For the authorities, who were devoid of a thought out/carefully prepared and consequent viewof knowledge and by that also of pedagogics, the information technique was the foremostcause of a change in pedagogy. The researchers also perceived the possibilities of IT, butemphasized the importance of pedagogical innovations irrespective of the technology.

Väljaren i centrum? En jämförande studie om valkretsrepresentation

In this essay I discuss and analyse if we can witness any signs on regional dimension due to regional representation from our elected representatives in the five constituencies Malmö, Blekinge, Norrbotten, Uppsala and Stockholm. Two seperate terms of office between 1991-94 and 1998-2002 has been compared. In political science there has been much debate about the relationship between voters and their elected. By measuring each and everyone elected representatives in the work of produce introduced bills towards their own constitiency during both terms I have tried to see if there is an occurence of a regional dimension.The theory that´s been applied is based on geographical representation where one might aspect that central metropolitan areas and peripheral regions is somewhat over-represented in legislatures. By using a method of comparison between the five chosen constituencies and theirs elected representatives I have come the the conclusion that there is a weak tendency that this might be the case seen to a regional dimension perspective..

Matförgiftad? Kanske ett införande av Smiley system i Sverige skulle kunna hjälpa dig?

Most of us sometimes in life visit a restaurant to relax and eat some good food. In that case, we trust that the food they are serving is of good quality and safe which prevent food poisoning. As a consumer you mostly do not have any insight what?s happening in the kitchen at the restaurant. What is really going on when they prepare the food? An introduction of the Smiley system could help you as a consumer in the choice of restaurant.

Inte för alla -­? En kvantitativ studie om journaliststudenters representation av allmänheten i Nicaragua

In our bachelor thesis we have strived to examine the representation of journalism students in Nicaragua. The freedom of press is much lower compared to Sweden and the journalist profession is protected by a certificate. It is also a high level of corruption within the country. Our investigation concerns who has access to the journalist education and the goal is to compare that with the public in Nicaragua. To be able to examine the representation among the journalism students we have chosen seven different aspects to examine, the sex of the student, witch social class they belong to, their academic background, religion, ethnicity, geographical belonging and political view.

Framväxten av den icke-euklidiska geometrin

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Utomhusundervisning för att främja lärandet - En pedagogisk undersökning om minnet och inlärning

Grundtanken med detta arbete är att se om utomhuspedagogik möjligtvis främjar lärandet och om det går att finna stöd inom neurologisk forskning för att ta reda på om lärandet stimuleras vid användandet av utomhusundervisning. Undersökningar har genomförts för att se om lärare och elevers syn på utomhusundervisning sammanfaller. Arbetet bygger på litteraturstudier, intervjuer, en observationsstudie, samt enkätundersökningar för att besvara forskningsfrågorna. I denna studie har det framkommit att utomhusundervisning främjar lärandet, främst beroende på de multipla sinnesintryck som utomhusvistelsen skapar. Denna iakttagelse stöds även av neurologisk och pedagogisk forskning.

Chalmers oanvända datorkraft - Distribuering av arbete och energihantering med HTCondor

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Säkerhetsmedvetenhet vid daglig IT-interaktion hos hemanvändare

Dagligen interagerar människor med IT-system och internetanvändning har blivit en viktig del i många människors liv. Med fler användare än någonsin hanteras ofantliga mängder information och samhället ställer allt högre krav på IT-säkerhet. När det gäller att skydda sin integritet, tillgänglighet och sekretess vid internetanvändning fokuseras det ofta på tekniska åtgärder, såsom brandvägg och antivirusprogram. De tekniska åtgärderna skyddar användaren till viss del, men det räcker inte för att förhindra ett bekvämt och naivt mänskligt beteende. När säkerheten brister beror det oftast på den mänskliga faktorn.

 Information Hold :  Ways of preventing information overload in Scania vehicles in critical traffic situations

De tekniska system som tävlar om förarens uppmärksamhet i bilar och lastbilar ökar både i antal och komplexitet. Detta kanske inte är ett problem på en rak, lugn motorväg men minskar fokus på själva körningen och om något oväntat skulle hända kan konsekvenserna bli allvarliga eftersom föraren är distraherad och kan behöva ta in för mycket information på en gång.Syftet med projektet var att utveckla ett system för att presentera endast relevant och önskad information till förare av lastbilar och bussar i kritiska trafiksituationer. Detta för att göra det möjligt för föraren att fokusera mer på körningen och därigenom göra den säkrare och bekvämare. Å ena sidan ska systemet upptäcka vilken typ av trafiksituation lastbilen befinner sig i. Å andra sidan ska det avgöra vilken typ av information som skulle vara relevant för föraren i den situationen.Med en litteraturstudie, insamlad statistik, intervjuer och författarnas åsikter som grund identifierades ett antal händelser (som telefonsamtal och förekommande varningar) som kan inträffa i förarhytten på en lastbil och hur mycket de vardera skulle öka förarens arbetsbörda (workload).
