Utvärdering av prototypen för ett kollaboratorium inom biblioteks- och informationsvetenskap

This study is a formative evaluation of a prototypecollaboratory for sharing data collection instruments inlibrary and information science (LIS). The aims were to findout: how the study participants, five hospital librarians,experienced the interaction with the prototype while workingwith predetermined tasks; and their views on the differentfunctions of the prototype collaboratory.Methods used for data collection was as a survey; followedby a think-aloud session where the participant verbalisedhis/her thoughts during the interaction with the prototype;and finally a semistructured interview. The survey wasanalysed with a frequency distribution, while the data fromthe other methods were analysed qualitatively by extractingthemes from the transcribed sessions.The results show that although the librarians expresseddifferent problems while working with the interface, mainlyrelated to the language in the prototype collaboratory anddifficulties with the page for applying metadata, all of themwere confident in being able to learn the system after using itfor a while. The librarians had a positive attitude towardssharing data collection instruments as well as comments inthe prototype collaboratory. At the same time, they wereaware that students and researchers might have differentabilities or incentives to work and share information.

?I just search the Internet?: En intervjustudie om internationella studenters informationssökning

The aim of this Master?s thesis is to investigate international students? views regarding information seeking and use of information sources. A further aim is also to investigate the possible factors influencing information seeking in relation to everyday life for international students. Interviews were carried out with eight international students, 20-35 years old from three continents. They were to stay in Sweden for at least five months for the purpose of studying.

Diskussioner inommatematikämnet : Kreativa och Imitativa diskussioneroch när de används i undervisningen

The purpose of this essay is to examine when teachers choose to discuss mathematics withstudents rather then just talk about mathematics. A definition where used to distinguish betweenan interaction that is not a discussion and an interaction that is a discussion. This definition hasbeen created by drawing ideas from other works into making a quite simple definition whichtherefore is easy to observe. The discussions are also separated into two different kinds ofdiscussions. The first and most common category of discussion are one where only imitativereasoning is used.

Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning

To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.

Hallå, är någon där? : En studie om informationsnyttjande mellan handelskanaler

Syftet med denna studie har varit att undersöka hur företag samlar in och utnyttjar kundinformation mellan försäljningskanalerna. Men även att utreda motiven bakom att bli en multikanalåterförsäljare samt produkttypens roll i beslutet. En kvalitativ fallstudie med semistrukturerade intervjuer har tillämpats, där fyra företag och en expert deltagit. Studien har visat att information om kunden har varit värdefull och har använts emellan handelskanaler för att anpassa butikens sortimentsmix, skapa välgrundade kampanjer och styra kunder till butik. De mindre företagen, sett till omsättning, har haft mer användning av kundinformation vid beslutet att öppna fysiska butiker än de större.

Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

Kontrollerad vokabulär eller naturligt språk? En empirisk studie.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

Närvarodetektor med IR och ultraljud

En närvarodetektor i form av en IR-detektor uppfyllde inte de önskade kraven och Eluw Electronic AB hade planer på att utveckla produkten vidare. IR-detektorn registrerar endast rörelse på en person vilket inte alltid är tillräckligt i företagets anläggningar. En person som inte är i rörelse måste också detekteras för att upprätthålla säkerheten runt en specifik anläggning. Företaget efterfrågade en närvarodetektor som klarade båda dessa detekteringar. Ett examensarbete på Luleå tekniska universitet löste uppgiften och en väl fungerande närvarodetektor med IR och ultraljud har utvecklats.

Samkörning av databaser-Är lagen ett hinder?

Title:Comparison of databases ? Is the law an obstacle?Authors:Alexander Ankarberg, Applied Information Science.Tutors:Lars- Eric LjungProblem: Cross running databases is getting more and more significant during the development of the information flow. There are huge benefits if we start to use the technique that already exists. The law is today an obstacle, so what would happen if the law wasn?t so stern.

Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar

In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.

Interventioner som reducerar oro inför och under anestesi hos vuxna patienter

BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal

There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.

Kvalitet på vägdata : inventering av skogsbilvägars standard samt jämförelser med lokal bedömning och SNVDB.

During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality. Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.

Integrationsprojekt på två bibliotek: mångfald, möten och möjligheter

Integration projects at two libraries: multiculture, meetings and possibilities takes its start in the fact that Sweden is populated with people from many different nations. The libraries have a unique possibility to arrange integration projects as a supplier of culture and information. This case study focuses on two integration projects arranged by two libraries; the library of Jönköping with the project Brobyggarbiblioteken, and the library of Kortedala which was involved in the project Ordbron. My purpose is to find out how these two libraries chose to work with integration, migrants and multiculture. The aim is to examine if the library could function as a passway to the Swedish society, and to find out if the library can facilitate for migrants to maintain contact with their native country.
