Bortglömda nyheter : En pilotstudie om hågkomsten av nyheterna i Dagens eko kvart i fem

In this essay a pilot study on the memory of Swedish Public Service radio news is presented. 30 subjects participated in the study, which was performed during three days, 18 to 20 of November 2013. The material which formed the basis for the study consisted three newscasts of Sweden's most popular radio newscast ?Dagens eko?, which is broadcasted live at 16.45 every day in the Public Service channels SR P1 and SR P4. The subjects listened to the broadcasts each day, and their memory of them was tested the day after each broadcast.The aim of the thesis is to find out which properties of the audience that affect how much ? and what parts ? of a newscast that the audience remember.

Micro plastics in the oceans and their effect on the marine fauna

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Simulering av valkar i pappersrullar : och analys av de slappa stråk som uppkommer

A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.

Instrumenteffekt inom användbarhetstestning : Mätinstrumentets påverkan på ett systems användbarhet

Fältet för användbarhetstestning är fullt av metoder, men av någon anledning är det en väldig brist på studier som jämför metoderna mot varandra och kontrollerar om dessa metoder, som utger sig för att generera samma typ av data, faktiskt är likvärdiga. Denna studie jämförde två användbarhetstestningsmetoder vid namn SUS och PSSUQ. Först jämfördes metodernas metamedelvärde med varandra för att se om det fanns signifikanta skillnader mellan metodernas rådata och sedan utökades analysen till att jämföra metodernas resultat med den normativa mall som respektive metod ger tillgång till. Dessa två olika jämförelser gjordes ett flertal gånger med olika antal försöksdeltagare vid varje iteration.Resultatet av studien visade att inga statistiskt signifikanta skillnader fanns mellan metodernas metavärde (värden transformerade till en skala mellan 0 och 100) och att inga statistiskt signifikanta skillnader hittades mellan dessa två mätinstrument då deras resultat jämfördes mot de normativa mallar som metoderna ger tillgång till, men även om inga statistiskt signifikanta skillnader hittades visar resultatet på en viss skillnad i hur ett system uppfattas beroende på vilken metod som används, vilket innebär att liknande studier borde genomföras..

Bloggtider för bibliotek och bibliotekarier? - Studie om bloggars användbarhet i bibliotekssektorn

The usability of the Internet increases for every year. The Weblog phenomenon makes it possible for anyone to easily publish, find information and get in touch with other people through the net. This Essay treats the possibilities the Weblog medium offer Swedish libraries and librarians in library contexts. The purpose of the study is to examine the Web phenomenon: Weblogs, and their significance for a total of eleven Library Heads and librarians together with their view on the Weblog activity at each library connected Weblog, to get comprehension and new knowledge on the usability of Weblogs in the library sector. The foundation for the Essay consists of a qualitative interview study, built on asynchronous e-mail interviews and telephone interviews with blogging librarians and Heads of libraries.

Utveckling av beslutsstöd för kreditvärdighet

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.

Indexeringens dilemma. En analys av förutsättningarna för ämnesindexering av skönlitteratur i förhållandet mellan indexeringen och dess objekt.

This thesis analyses the conditions for subject indexing of fiction by studying the relationship between the nature of fiction and the properties of subject indexing. The analysis is founded on a reading of a recently published Swedish subject headings list and uses a theoretical framework of Adornos theory of modern reason. The study is conducted through a qualitative text analysis in three steps. In the first step the subject headings list is analysed by examining how it provides subject access to fiction by the aspects of form, frame and subject. In the second step of the analysis these aspects of subject access are analysed and discussed by relating them to relevant research of subject indexing of fiction.

V?RMEAKTIVERADE TISSUES P? TRANSPARENT PAPPER En j?mf?rande studie vid revlagning

Works on transparent paper, also commonly known as tracing paper, have been described as ephemeral or temporary working documents and they usually number large quantities in archival and museum collections. They have therefore previously been considered of lower priority and can be found in poor condition due to a lack of treatment or suitable storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common solution in archives for the treatment of water-sensitive works on paper has been the use of heat-activated tissues as they can be applied without the introduction of solvents. There is little published about the use of heat-activated tissues on transparent paper and is mentioned only briefly in existing literature.

Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

Iterera, iterera, iterera : En studie om hur en upprepande designprocess kan förbättra användbarheten i Provbankens interaktiva distansprov

Provbanken är en del i ett nationellt provsystem som är tänkt att vara ett bedömningskomplement till existerande prov i gymnasieutbildningen. Växjö universitet har varit delaktig i utvecklingen av prov för de yrkesinriktade ämnena sedan 1997. Eftersom innehållet i dessa numera webbanpassade prov är det väsentliga, måste utformningen av provet göras lättförståelig. Användbarheten måste m a o vara självklar och inte ställa till problem för användaren. Som en av utvecklarna av dessa interaktiva prov, ville jag finna ett sätt att minimera problemen och öka användbarheten.

TV-stativ med nytt ställdon

The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.
