Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Allmänhetens arkiv? : En studie av tre participatory archives

The aim of this study is to examine how and in what way users of the public participate and affect the archival information that is to be preserved for the future through the examination of three archival projects involving public participation. The study seeks to examine if participation of the public could lead to increased democracy and diversity of information in the archives. The study will be performed through the examination of three participatory archives all tied to traditional archival institutions.The study is based on the theoretical framework of Benn and Gaus and their notions of public and private which they discuss using the key words access, agency and interest. The study also takes into consideration Laura Millar?s theories of social memory as a means for the public good.

Bayesiansk klassificering av ursprung för fångster av sill

Sammanfattning I september 2008 fångades 311 juveniler (unga individer) av arten sill (Clupea harengus) in vid fyra olika områden på den svenska västkusten; Råssö, Hunnebo, Askerö- och Gullmarfjorden. Genetiska, kemiska och morfologiska data (längd och vikt) samlades in i syfte att bestämma vilka populationer de härstammade ifrån. Fångster av sill är så gott som alltid av blandat ursprung eftersom individer bara samlas i de populationer de stammar ifrån vid den tid på året då det är dags för parning (lek). I den här uppsatsen klassificerar jag juvenilerna till tre regioner i vilka populationerna ingår, genom att jämföra de data som samlats in från juvenilerna med motsvarande data i en stor databas över populationer i Nordsjön, Skagerrak, Kattegat och Östersjön samt med ytterligare en population, Risør, som inte ingår i denna databas. Data om populationerna kommer från samples och de sanna populationsparametrarna (dvs.

Parkkaraktärer : ett verktyg för planering och gestaltning av grönområden

An increasing number of peole are resisting the attraction of living around nature and opting instead to spend their lives in cities. Parks and green areas play an important part in our well-being and we become fascinated with the diversity of nature, in which we find a peacefulness that is unique. Amongst other things, being surrounded by nature can reduce high blood presure, lower the production of stress hormones and stimulate the mind and our ability to concentrate. It is therefore vitally important to entice city residents to parks and green areas to improve their physical and mental well-being. Previous research has shown that humans are seeking for certain characteristics in the parks and green areas which they are visiting.

Mellan digitalt arkiv och socialt forum - en idéanalys av visionerna bakom biblioteksportalen Europeana

Digitizing and digital libraries create great opportunities toprovide access to cultural heritage globally, but the quicklychanging information technology environment also raises manyquestions. The aim of this bachelor thesis is to analyse whatvisions and ideas behind one specific digital library, Europeana,that can be found in documentation related to the project. Whatideas can be identified concerning aspects such as userparticipation, access to information, knowledge andinformation literacy? What is the project?s role in relation toeducation, preservation of cultural heritage and democracy?The method used to answer these research questions is adescriptive idea analysis. The empirical material, consisting ofprimary sources written in relation to the project, has beencategorized within dimensions and analysed according toDouglas Raber?s three public library strategies: social activism,the conservative response and the populist initiative.

Liv i d?d ved: En unders?kning av f?rh?llningss?tt till d?d ved p? ?ppeltr?d i tr?dg?rdshandb?cker och bland yrkesverksamma tr?dbesk?rare

In this essay, several factors in apple tree care (specifically in relation to whether dead wood should be kept or removed) are highlighted for example, aesthetics and biodiversity. To present some background, the essay begins by introducing some previous literature on dead wood. This leads into how dead wood is treated within forestry. Next, previous research on dead wood in fruit trees is mentioned. Cultural and historical management methods are also highlighted.

Genetisk bakgrund till ataxi hos hund

Ataxi är då hunden har svårt att koordinera sina rörelser och orsakas av att nervsystemet inte fungerar som det ska och degenereras. Degeneration av cerebellum och då specifikt purkinjecellerna och granulacellerna ger en form av ataxi kallat cerebellär ataxi. Denna typ av ataxi uppvisas genom att hunden (Canis lupus familiaris) står bredbent, har muskelkramper, obalanserad gång och ögonrullningar. Den genetiska bakgrunden till cerebellär ataxi hos hund finns beskriven hos flera raser, däribland beagle, finsk stövare, old english sheepdog, gordonsetter och coton de tuléar. Hos alla dessa raser nedärvs sjukdomen autosomalt recessivt och de orsakande mutationerna ger olika dysfunktioner inom nervcellerna som gör att de inte kan fungera som de ska och degenereras.

Kvinnliga virkesköpare inom Holmen Skog

Holmen Skog has only five out of 70 wood buyers who are women, This report is seen as a step in the process towards gender balance in the company. This is a problem that is equal over the entire forest industry in Sweden. They all think that sexual equal workplaces are very important to remain competitive, see things from different perspectives and development of the company. The survey was done by sending out questionnaires to all women who work and have worked as a wood buyer at Holmen, and as many men of both categories. These four categories became a total of twenty persons. To map the industry another questionnaire was sent out to the six largest forest companies in Sweden. The survey found that female wood buyers not finished their work earlier than men did, as they thought before.

Fantastiskt eller vidrigt? : Uppfattningar om genmodifierad mat

Med genteknik är det möjligt att ändra gensammansättningen i våra livsmedel och applikationen har väckt stort intresse, inte minst bland allmänheten. Genmodifierade (GM) livsmedel har varit föremål för diskussion sedan 1970-talet. Syftet med denna uppsats är att studera olika uppfattningar och representationer om genmodifierade livsmedel. Enligt teorin om sociala representationer har representationer dubbla funktioner. Den ena är att konventionalisera objekt och den andra innebär att representationerna intar en förutbestämd form.

Varför bor Luis i slummen? : En kvantitativ undersökning om hur folk framställs i en serie skolböcker

Teching aid in form of schoolbooks plays an importent role. The teacher uses schoolbooks as a tool in its tutoring. I have examined how and whether the pictures in the schoolbooks are presenting people and ethnic minorities biased and stereotypical. The material I have examined consisted of a series of schoolbooks (So-direkt 1-3, samhällskunskap av Bonnier 2003).To find out if that is the case I have used a theory by Stuart Hall, his theory is about people and how they are represented in different types of media, like pictures and text. I studied it by using the method of image analysis where I investigated and interpreted the denotation and konnontation of the pictures.

Offer, aktör eller överlevare? : En diskursteoretisk analys av unga tjejers utsagor om att leva med sex som självskadebeteende

The purpose of this study is that through a discourse theoretical perspective, analyze young girls 'statements about living with self-injuring by sexual behavior. The aim is to locate the discourses that surround them, visualize how discursive constructions affect these young girls' identity as victims and/or actors in relation to self-injury, the sexual violence and in meetings with the professionals within the health authorities. In addition discourse theory as an analyze method, the authors also use Nils Christie's (2001) theory of the ideal victim and Ingrid Landers (2003) theoretical perspectives on normative femininity. The authors of the study show a diversity of discourses that surround the young girls. All discourses contain normative actor- and victim?s positions that young girls constantly are obliged to relate to, which partially conflict with social constructions of the idea of victim and femininity.

Fine-Mapping of Equine Multiple Congenital Ocular Anomalies on horse chromosome 6

Multiple Congenital Ocular Anomalities (MCOA) is a genetic disease that affects primarily Silver coloured horses of breeds such as the Rocky and Kentucky mountain horses. In these breeds the Silver dapple colour is very popular leading to an increase of affected horses. The major feature of the disease is ocular cysts of variable size. Large cysts also lead to a variety of secondary syndromes, for example retinal detachment. In previous studies the locus for MCOA has been mapped to an interval of 420 kb on equine chromosome six.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Dopning vid hästbesiktning

The aim of the project was to investigate if Swedish rodents, brown rat (Rattus norvegicus), house mouse (Mus musculus), wood mouse (Apodemus spp) and water vole (Arvicola terrestris) captured in pig herds and in urban areas, constitute a reservoir for pathogenic Leptospira spp. Under Swedish conditions leptospirosis gives rise to reproductive disorders in pigs and symptoms of flu in humans. It has long been established that rodents are chronic carriers of pathogenic leptospires in their kidneys, and can spread the bacteria with urine. The old nomenclature of serovoars is still in use, but a new system of genetic classification has developed and today the genus Leptospira contains 17 species. There are several diagnostic test developed for leptospirosis.

Relationen mellan interkulturellt ledarskap och praktisk kunskap

My essay is concerned with intercultural leadership and practical knowledge. The essay is about ethical dilemmas and the diversity of issues we face constantly at the preschool. In my story I examine the different views of knowledge and the opportunities to lead people in an intercultural way, and how they relate to each other. I start by looking at the ethical ideas that form the basis for our actions and our view of knowledge. Then, I examine how the practical wisdom guides the ethical dilemmas that arise at the preschool.
