Betydelsen av utfodring under sintiden, sintidens längd och kalvningsintervallet med avseende på kons hälsa under kommande laktation
This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.
Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager
It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006). Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.
Bilden av "Balkan" : Krigen i forna Jugoslavien på svenska ledarsidor 1995
This paper examines the existence of two different discourses on the causes of the wars in former Yugoslavia 1991-1995 in the editorial pages in Swedish newspapers. One discourse is titled "ancient hatreds" and explains the wars as a result of old historical ethnic conflicts typical of the "Balkans" and the second discourse, "poor political leadership," explains the wars as a result of deliberately conducted nationalistic policies by political leaders.Parallel to this discourse analysis is a media theory perspective of how news is selected and processed in the newspaper's editorial texts.The paper also examines the link between each discourse and a specific view on the necessity of foreign military intervention in former Yugoslavia.The starting point of the investigation are two high-profile events in 1995 and the impact they made in the 29 editorial texts in the metropolitan newspapers that were studied.The paper shows that none of the discourses clearly dominated in these editorial texts and that a clear link between a certain discourse and the advocated measure in the form of foreign intervention couldn´t be established in the material as a whole. However, the four texts that clearly belonged to the "ancient hatreds" discourse were all in favour of foreign military intervention.The essay concludes that there is evidence of a medial feedback which means that the news to a high degree influences what is discussed in the editorials and that the evaluation and selection of news, is similar in all the studied newspapers..
Folkbibliotekens webbplatsers grafiska användargränssnitt Kvalitativa intervjuer med webbansvariga
The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.
Man eller kvinna - Låt myter om förövaren försvinna : En diskursanalytisk studie av hur personer som begått sexualbrott mot barn framställs i svenska dagstidningar
The aim of this study is to identify the dominating discourse in Swedish newspapers concerning perpetrators who committed sexual offence against children. The study is based on the idea that the media representation play a significant role to the public opinion and awareness of the perpetrators. The study is based upon a selection of 103 articles published between January 2003 and November 2013, taken from four of the biggest daily newspapers in Sweden; Aftonbladet, Dagens Nyheter, Expressen and Svenska Dagbladet. The methodological and theoretical approach in the study has been the one of discourse analysis through which one dominating discourse along with two subsidiary discourses could be identified. The discourse considered to be dominating is the one who presents the perpetrators through the discrepancy between the actions committed and the description of the perpetrator.
Vertikal trädgård i kallt klimat : en undersökning av ståndort, växtval och vinteraspekt
I takt med att städer förtätas och befintliga grönytor försvinner växer behovet av att hitta innovativa och fungerande lösningar för annan typ av grönska i städer. Utomhusväxtväggar har kommit att bli ett allt vanligare fenomen i södra Europa och andra delar av världen. I det bistra svenska klimatet är dock ståndorten på vertikala ytor att betrakta som extrem och vissa växter som trivs på det horisontella planet har inte en chans att överleva i det vindutsatta läget med stora temperaturskillnader. Detta arbete syftar till att underlätta växtvalet så att det blir möjligt att skapa såväl fungerande som estetiskt tilltalande utomhusväxtväggar i framtiden. Genom studier av litteratur på ämnet samt intervjuer med aktiva inom området undersöker detta arbete huruvida det finns gemensamma egenskaper hos de arter som faktiskt kan överleva under de tuffa förhållandena.
Resultatet påvisar att vissa samband i härdighet och naturståndort går att se men att många faktorer har betydelse för växternas överlevnad och att för få växtarter ännu testats.
LIDESK : En materialstudie för Edsbyverken
Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.

Könsselektering av spermier från lantbrukets husdjur
Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.
Varumärkesidentitet och image ? En studie om Lindex och Prada
Competition is keen in the fashion industry of today. Homogenous products and prices aredriving competition and most firms are struggling hard to attract customers. Brands havebecome one of the most important assets for success and are often critical for the choices of theconsumers. A strong brand is often considered as a substantial value in the eyes of the consumerand gives the individual firm a competitive advantage in the marketplace.

Informationssökning och lärare: En studie av 4-9-lärare i övergången från utbildning till yrkespraktik
The main purpose of this Masters thesis is to contribute to the understanding of high school teachers information seeking behaviour in the transition from university studies to occupational practice. The theoretical framework encompasses theories of professional socialization, the sociology of knowledge, of professions, and of library and information science. The empirical material has been collected through interviews with six recently qualified high school teachers in different subjects. The interviews have been analysed on two different levels; first on a descriptive level and then on a theoretical level. The major findings are that the academic context limited the student teachers information seeking and they did not have the opportunity to choose cognitive authorities on their own initiative.

Anorexia Nervosa - en fast identitet i en flytande modernitet? : En kvalitativ undersökning av individer som utvecklat anorexia
The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.
Användarvänlig design av bibliotekskataloger på webben.
The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.
