The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Bakgrund: Postoperativa sa?rinfektioner a?r en vanligt fo?rekommande va?rdrelaterad infektion, och orsakar stort lidande fo?r patienten och stora kostnader fo?r sjukva?rden. Diabetes a?r en riskfaktor fo?r att utveckla postoperativ sa?rinfektion, och har liksom hyperglykemi fysiologiska effekter som bidrar till en o?kad risk att utveckla postoperativ sa?rinfektion.Syftet med denna studie var att underso?ka sambandet mellan diabetes, postoperativ hyperglykemi och postoperativ sa?rinfektion hos patienter som genomga?tt CABG-kirurgi.Metod: Studien designades som en kvantitativ retrospektiv studie med deskriptiv ansats. Data insamlades dels fra?n va?rdenhetens egen infektionsregistrering, dels genom granskning av 276 patientjournaler pa? den aktuella va?rdenheten.

Since Sweden joined the EU in 1995 there has been a noticeable increase in the value of arable land occurred. This paper is intended to study the inflation of farmland prices. In order to ascertain what affects the market prices so much since Sweden affiliated with the EU three regions has been selected for a detailed study on the subject. These three regions are selected because each of them represents different parts of the Swedish farmlands. The time period that has been examined is the year 1995 until 2009.The price raises in the three observed regions was overall fairly even at the end of the studied period.

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

The aim of this two years master thesis in Library and Information Science is to examine how librarians and library managers in the three Stockholm suburbs of Alby, Fisksätra and Rinkeby think and reason about the role of public libraries in the integration process. The aim is also to examine whether their perception differ from that of local politicians at the municipal level. The theoretical framework is Marianne Andersson and Dorte Skot-Hanses model for analysis of the local library profile, and Jose Alberto Diaz theory on the integration process. The method used is qualitative interviews. The interviews were recorded and the content was analyzed using qualitative content analysis. The results of this study show that the library services in the three suburbs, rather than being stipulated by the legal demand for special services towards immigrants, are based on the needs of the local population.

The proportion of women entrepreneurs in Sweden is, as in many countries, smaller than the proportion of men entrepreneurs. Sweden has therefore created political measures with the ambition to increase women entrepreneurship. However, knowledge about the determinants of women entrepreneurship is needed in order to enable the promotion of it and, at the same time one can question the treatment of women entrepreneurs as a homogenous group. The purpose of this thesis is to investigate the determinants of women entrepreneurship and whether these determinants fluctuate regionally. If this proves to be the case, a more spatial/individual approach should be used, when creating measures to promote entrepreneurship.

Över hela världen pågår en kraftig urbanisering och idag lever mer än hälften av alla människor i städer. Många utvecklingsländer hinner inte med att generera hållbara och alternativa försörjningsmetoder till den allt större urbana befolkningen. Allt fler lever i en tillvaro som präglas av fattigdom. Kraftfulla planeringsstrategier krävs för att förbättra dessa människors levnadsförhållanden och därmed också verka för en hållbar utveckling. Uppsatsen presenterar det urbana jordbruket som en i dessa avseenden möjlig strategi. Urbant jordbruk finns i alla städer och har gjort det i alla tider.

The Swedish population has the world?s largest percentage of shareholders either by direct or indirect owning. Due to the increasing interest of equity capital markets, private as well as institutional investors rely on forecasts from financial analysts. The reason for this is due to the lack of expertise among investors in this area. Due to the fact that analysts influence the Swedish stock market immensely, it?s of great interest to explore whether an analyst can be seen as a rational participant.

The aim of this study is to investigate where and why the fitness clubs, Sats and Friskis & Svettis in Stockholms county, choose to locate their facilities in certain places and which their primarily targetgroups are. Furthermore, the aim is to gain knowledge of people?s health status in areas where the facilities are located, in order to see if they are located where exercise is most needed. Interviews were conducted with members of the fitness clubs but also with non members, i.e. people who lived in areas with an absence of fitness facilities.

SyfteSyftet med studien var att undersöka inter- och intrabedömarreliabiliteten för rörelseanalysen ?9+ screening batteri? hos en grupp unga fotbollsspelande flickor med avseende totala bedömningen av rörelseutförandet. MetodTolv friska fotbollsaktiva flickor (13-14 år) deltog i studien. Testerna genomfördes vid två tillfällen med sju dagars mellanrum. Screeningbatteriet bestod av elva funktionella test samt tre tilläggstest. Utförandet bedömdes av sex sjukgymnaster som alla hade liten vana av att använda testbatteriet. ResultatGruppen hade ett medelvärde på 17.2 ± 1.3 (95 % CI; 14.4?19.9) vid testtillfälle 1 och 17.4 ± 1.8 (95 % CI; 13.4?21.5) vid testtillfälle 2 av totalt 33 poäng.

There has been almost no research on whateffects the sex education has had on the general population in Sweden. Aim: The aim for thisstudy has been to look at middle school teacher?s ways of conducting and there conditions insex education.

As an effect of increased living standards and improved health care, life expectancy has risen in many parts of the world. At the same time, welfare diseases such as diabetes and obesity increases. As the number of elderly and long-term sick rises, so will the medical care needs. E-health applications are often presented as a way to meet future medical and doing so within the scope of existing resources. By facilitating health communication and widen access to health services by offering them online, e-health applications encourages people to become more engaged in their own health, thus working proactively towards a healthier population.

Knäskador inom fotbollen är tre till fem gånger vanligare hos flickor än pojkar i ung ålder. Genom att träna balans, benstyrka, bålstabilitet och koordination kan knäkontrollen öka. Svenska fotbollsförbundet har utvecklat ett träningsprogram i syfte att förebygga skador, ?Knäkontroll, förebygg skador ? prestera bättre?. Det finns olika sätt att utvärdera knäkontroll, ?Hop for distance?, ?Square hop? och ?Side hop? är hopptester som kan användas.

Vildbiet guldsandbi (Andrena marginata F.) har en central roll i jordbrukslandkapet som en viktig pollinatör av grödor och vilda växter. I Sverige hotas artens fortlevnad av biotopförlust, habitatfragmentering och födobrist. En av de viktigaste näringskällorna är växten ängsvädd (Succisa pratensis M.) som tidigare var vanligt förekommande men som nu minskar i sin utbredning. Syftet med denna studie var att utreda om populationsstorlekarna av guldsandbi och ängsvädd är relaterade. Guldsandbinas observationsbaserad populationsstorlek uppskattades samt att ängsväddens bestånd inventerades vid fyra lokaler i Övre Klarälvsdalen, i norra Värmland.
