Porr och rasistisk propaganda på svenska folkbibliotek : skall folkbiblioteken tillåta ett fritt internetanvändande eller skall man kontrollera sina internetterminaler?
This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.
Svensk kunskapsorganisationsforskning 1990-2002
The purpose of this study is to characterize the research in the field of Knowledge Organization, during the period of 1990-2002, focusing on the subject and the epistemology of these studies. The result shows that studies concerning representation, e.g. subjects such as classification, indexing and bibliographic description, are the most frequently researched areas throughout the period. Classification was more popular in the beginning of the period, but later bibliographic description, mostly with studies on metadata, became more visible, together with a growing interest in information retrieval. The theoretical discussions in the studies focused primarily on document analysis and the organization of digital documents.
Ett verktyg för konstruktion av ontologier från text
With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.
MEASUREMENT OF C-REACTIVE PROTEIN IN CANINE SERUM ON KONELABAUTOANALYZER 20
An inflammatory reaction is induced after release of proinflammatory mediators such asinterleukin 1 and 6 and tumour necrosis factor ?. These mediators stimulate the liver tosuppress the syntheses of albumin and endure the syntheses of acute phase protein forinstance C-reactive protein. The aim of this paper was to perform a method validation on animmune turbidimetric assay to quantify C-reactive protein in canine serum at the laboratory atSkara Animals Hospital, Skara, Sweden. The validation involved evaluation of the assaylinearity, precision, stability and recovery.The method was proved to be linear for both TruLab control and Medinor control.
A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT
Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls.
Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem.
The diabetic pigs were insulin treated and responded well.
Jämförelse av olika veterinärers bedömning av hälta hos häst
The most common reason for a horse owner to seek veterinary care for their horse is related to the musculoskeletal system. Assessment of the horse's movement pattern is essential in the equine veterinary work. How uniformly veterinarians evaluate the lame horse may have both diagnostic and prognostic significance, such as follow up examination by the same or different veterinarian. The purpose of this study was to evaluate whether there are between-veterinarian differences in assessing lameness in the same horse. In total 12 veterinarians evaluated 80 video sequences of 4 horses with induced lameness and made an evaluation of the affected limb as well as the degree of lameness.
Är läraryrket en bortglömd profession? : En kvalitativ studie av styrreformernas påverkan på läraryrket
The study takes place in the capital of Sweden, Stockholm. It focuses on how the past reforms since the 90s have changed the teachers? occupation as a profession.The study is partially based on analysis of prior research and documents related to the thesis. The cornerstone of it is based on four immerse interviews carried out in three different schools. Two of which were private schools and the third is a municipal school.
Platsbaserad sökning : En metod fo?r filtrering och sortering av so?kresultat
Informationsso?kningar av olika slag sker dagligen va?rlden o?ver och so?kresultatet kan ma?nga ga?nger vara sa? stort att anva?ndarna har sva?rt att veta vilka so?kresultat som a?r relevanta. I denna uppsats har syftet varit att underso?ka hur so?kresultat kan filtreras och sorteras med hja?lp av platsbaserad so?kning fo?r att det ska bli mer relevant fo?r anva?ndaren. Genom litteraturstudie och intervjuer har det blivit mo?jligt att ta reda pa? hur ett so?kresultat skulle kunna filtreras och sorteras fo?r att mo?ta anva?ndarnas fo?rva?ntningar.
Ämnesindexering av spelfilm
The aim of this thesis is to examine possibilities concerning subject access to fiction film, i.e. appropriate ways to describe fiction film for subject retrieval. Problems regarding subject indexing in general, and subject indexing of fiction film in particular, are identified, as well as the uniqueness of fiction film and film genres. Four types of subject aspects are discussed: form and genre, fictitious characters, setting, and general topics. Several guidelines, form- and genre lists, and subject headings lists are examined and treated as potential indexing tools.
Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Weblogindex: En studie av weblogindex utifrån Lancasters processmodell över traditionell indexering.
Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.
Kvinnors och mäns upplevelser av abort
Bakgrund: Den svenska abortlagen från 1 januari 1975, ger den gravida kvinnan rätt att själv bestämma om hon vill avbryta graviditeten. Mannens roll och behov nämns inte alls.Syfte: Att belysa kvinnors och mäns upplevelser och behov av stöd under abortprocessen.Metod: En systematisk litteraturstudie med 16 vetenskapliga artiklar analyserades och kvalitetsgranskades.Resultat: Litteraturstudien visade på abortupplevelsen som en jobbig period i livet men det resulterade även i en beslutsamhet och mognad.Diskussion: Resultatet tyder på att det är nödvändigt att få en ökad förståelse för den individuella vårdtagarens behov och förväntningar av vården och behandlingen. För att få en förståelse för mångsidigheten i abortsituationen bör man synliggöra både mannens och kvinnans delaktighet.Konklusion: Männens upplevelser av abortprocessen är föga outforskade. Sjuksköterskans roll i processen är betydelsefull och därför är det oerhört viktigt att personalen innehar kunskap och intresse att kunna bemöta dessa patienter..
Kunskapsteori och kunskapsorganisation: En diskursanalys
This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.
Förbättrad manuell styrning av staplingskran
Detta examensarbete är utfört hos Swisslog under våren 2013. De hade problem med den manuella styrningen av deras pallstaplingskran för höglager, som upplevdes ryckig och svår att kontrollera vid låga hastigheter.Huvudsyftet var att undersöka varför detta fenomen uppstod och hur det kunde lösas med både hård- och mjukvarumässiga metoder. Utöver detta undersöktes hur produktionskostnaden, för delarna av kranen som rör den manuella styrningen, kunde reduceras.Det upplevda fenomenet är känt som biodynamic feedthrough. Det innebär att konstruktionens acceleration matas genom operatörens kropp och skapar en återkoppling till styrdonet, i detta fall en joystick. Operatörens hand ger en oavsiktlig störsignal som gör systemet instabilt som i sin tur skapar en oscillation som ökar i amplitud och är svår eller omöjlig att stoppa.Den föreslagna lösningen är att digitalt lågpassfiltrera styrsignalen från joysticken.
Geoenergilösning för DN-huset
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.
