Social taggning: En studie av en webb 2.0 tjänst i OPAC

The aim of this thesis is to study social tagging in an OPAC by looking at the tags of Ann Arbor District Library?s catalogue. In this thesis I analyse the possibilities of social tagging. The main questions to be answered are what is the distribution of tags in different categories, what are the differences between fiction and non-fiction and how do the social tags differ from the terms of the professional indexing practice. Studying 500 tags I find that subject matter was the most frequent category for tags assigned to fiction and non-fiction.

Minskande andelar kraftfoder i foderstaten under betesperioden : effekt på mjölkavkastning och betesbeteende hos mjölkkor

Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.

Produktutbud av lignoser för norra Norrland :

Ett begränsat utbud av växter kan antas påverka privatpersoners trädgårdsintresse negativt. För norra Norrland begränsas utbudet av lignoser till dem som har tillräcklig härdighet. Det kan dock antas att fler lignoser utöver de som säljs idag, har potential att användas i denna del av landet. Detta examensarbete har som syfte att ta reda på hur försäljningen av lignoser i norra Norrland ser ut idag. Vidare undersöks också om en utveckling av lignosutbudet pågår och hur arbetet med denna utveckling i så fall ser ut. Vem eller vad som kan påverka så att fler härdiga lignoser kommer ut på marknaden har varit en central frågeställning.

Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna

This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.

Högt uppsatta kvinnliga chefer. : ? En studie om valet att sluta på ett stort svenskt företag.

Det finns idag fler personer som heter Johan som är VD i börsnoterade bolag än vad det finns kvinnliga VD:ar i Sverige. Uppsatsen är skriven om ett stort svenskt företag i näringslivet. Syfte med studien var att utvärdera varför kvinnliga chefer på höga positioner inom ett större svenskt företag i näringslivet har valt att sluta samt vad företaget kan förbättra för att bli en mer jämställd och attraktiv arbetsplats för kvinnor i chefsbefattningar. Forskning visar på att det idag 2013 fortfarande finns en hel del ojämställda arbetsplatser. Via kvalitativa semi-strukturerade intervjuer med sju kvinnliga före detta chefer på företaget har en bild av vad detta kan bero på skapats.

Utvärdering av traktplanering på Holmen Skog

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Att leta efter kännskap : Hur lärare ser på utemiljön som en miljö för lärande

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

En bättre värld genom faith? : En studie om hur organisationen DIAN Interfidei arbetar för att skapa fredliga relationer i Indonesien

En bättre värld genom faith? En studie om hur organisationen DIAN Interfidei arbetar för att skapa fredliga relationer i Indonesien [A better world through faith? A study about how the organization DIAN Interfidei works to pursue peaceful relations in Indonesia]. The aim of this study has been to analyze how an Indonesian NGO called DIAN Interfidei works with peacebuilding through faith in order to bring harmony between the various ethnic and religious groups of people that inhabits the nation. Through interviews and the study of Interfideis own source-material could their methods and problems be explored, and later on related to contemporary research in the field of conflict-resolution and peace-making. The conclusions that could be drawn from this study is that Interfidei primarily targets two specific groups (teachers of religion in schools and future religious leaders) in their programmes, because these groups in turn have the potential to affect several people in their own work.

Hur värderar människor utemiljön och dess funktioner? : två fallstudier - Tarapoto, Peru, och Uppsala, Sverige

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

Lämplighet i familjehem : En kvalitativ studie av godkända familjehemsutredningar

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.
