SUNET-satsningen på folkbiblioteken - en kartläggning av argumenteringen för och emot en anslutning

The purpose of this study is to analyse the offer from the ministry of education and cultural affairs to Swedish public libraries concerning a computerised connection to SUNET (the Swedish University Network). The study is based on analyses of the main texts from the campaign and interviews in order to identify arguments that caused the libraries to accept or decline the offer. My conclusions are that the marketing of the SUNET-offer was to a large extent filled with technicalities, and that the campaign failed to identify and focus on the true recipients the decision-makers. The wordings used in the written material were too negative and discouraging. In order to succeed with future concentrations concerning public libraries, it is vitally important to overcome the boundaries between the decision-makers in the local government, the people responsible for information technology and the library staff..

Analys av kvalitet i en webbpanel : Studie av webbpanelsmedlemmarna och deras svarsmönster

During 2012, the employer of this essay carried out a telephone survey with 18000 participants and a web panel survey with 708 participants. Those who partook in the telephone survey were given a choice to join the web panel. The purpose of this work is to study the participants of the telephone survey and see if they reflect the Swedish population with regards to several socio-demographic factors. Also, we intend to investigate if the propensity to join the web panel differs for participants of the telephone survey with regards to various socio-demographic affiliations. It is also of interest to study if the response pattern is different for participants of the telephone survey that would like to join the web panel and those who reject.

Expansion av sökfrågor med Svenskt OrdNät som termkälla

The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia

The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.

Klassiska populationsmodeller kontra stokastiska : En simuleringsstudie ur matematiskt och datalogiskt perspektiv

I detta tvärvetenskapliga arbete studeras från den matematiska sidan tre klassiska populationsmodeller: Malthus tillväxtmodell, Verhulsts logistiska modell och Lotka-Volterras jägarebytesmodell. De klassiska modellerna jämförs med stokastiska. De stokastiska modeller som studeras är födelsedödsprocesser och deras diffusionsapproximation. Jämförelse görs med medelvärdesbildade simuleringar.Det krävs många simuleringar för att kunna genomföra jämförelserna. Dessa simuleringar måste utföras i datormiljö och det är här den datalogiska aspekten av arbetet kommer in.

Population i isolering : en inventeringsutvärdering

Under 2005 och 2008 inventerades förekomsten av större vattensalamander(Triturus cristatus) i Gävleborgs län. Ett till synes isolerat fynd gjordes väster om Hofors. Inventeringarna utfördes med flaskfällor och visuell observation och lokaler valdes via kartblad enligt kriterier på vattenytans areal, rörelse och distans till väg. Syftet med detta arbete var att undersöka huruvida den observerade isoleringen var faktisk eller endast ett resultat av den använda inventeringsmetodiken. Detta arbete baserades på en radie kring en känd population där radien baserades på spridningsdistans, mognadsålder samt tid sedan den förra studien. Lokaler valdes sedan ut inom radien med krav på areal vattenyta och förekomsten av stillastående vatten varpå inventeringar utfördes med flaskfällor.

Hur framställs hälsa i media? : En diskursanalys av Aftonbladet, Tara och Iform.

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.

"Säg mig vad du äter och jag ska säga vem du är" : En kvantitativ studie om efterfrågan av hälsosamma livsmedel

Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.

Folkbibliotek som mötesplats för flyktingar : En undersökning av två folkbibliotek och deras potential att öka socialt kapital i samhället

This essay points at the importance of public libraries as arenas of meetings between refugees and the local population, and by this - creating social kapital in the society as a whole. The researchers Aabø, Audunson and Vårheim have created theories about low-intensive meeting places, that means ? neutral, public places where accidential meetings with different strangers can happen, which can create social capital and trust among each other. To complement these theories I also use Vårheim who have implementet social capital-theories to the sphere of public libraries. These two theories complement each other and can help me investigate two public libraries in a rural area in Sweden.

Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.

Integrationen av etniska minoriteter i de tre Baltiska staterna

This essay is a comparative empirical study of ethnic integration mainly of the Russian-speaking minorities in the three Baltic states (Estonia, Latvia and Lithuania) in a post-communism setting. As Lithuania has a Polish minority that is as large as the Russian-speaking, they too shall be included in the study but not as thoroughly as the Russian-speaking minority. Thus the problem is: to what degree are the ethnic minorities integrated with the titular nations in Estonia, Latvia and Lithuania? In order to study ethnic integration I have set up a theoretical framework largely based on Weiner?s theory of integration. The theoretical framework focuses on three dimensions: Citizenship, Identity and Segregation.

Kan grad av degenerativ hjärnsjukdom prediceras med hjälp av mått på kognitiv försämring?

Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.

Den svenska lapphunden - en ras i behov av förändring?

Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. Concerns have arisen and crossbreeding has been discussed as a way to manage gene loss. Four breeds has been taken into consideration for this purpose; schipperke, finish lapphund, Norwegian buhund and Norwegian elkhound, black. These breeds has been tested theoretical by a comparison of mentality and health.

Upplevelser av att arbeta med djur på daglig verksamhet : En kvalitativ intervjustudie bland personer med funktionsnedsättning

The central part in all public health work is health promotion and disease preventing actions among the population. Since all public health work includes the whole population, the work has to embrace disabled people as well. Within the disability policies, participation and equality are important goals, which illustrate the importance of a job. In previous studies the positive effects of animal have been detected among persons with disabilities, by better balance, better mobility, larger social network, new knowledge and most of all happiness. The aim of this study was to investigate how people with disabilities experience their health when they are working with animal husbandry at daily activities.
