Klövhälsa registrerad vid rutinmässig verkning i lösdrift eller uppbundna system med ekologisk eller konventionell mjölkproduktion :

KRAV-certified organic dairy herds generally have a lower milk yield than conventional dairy herds. A high-level of milk yield requires a feeding regime with high amounts of concentrates, a factor known to contribute to the development of claw lesions (Bergsten, C. 2003). The aim of this study was to compare claw health between organic and conventional dairy herds in free and tie stall systems. The number of herds from different domestic animal health associations was chosen in proportion to the association´s total portion of Swedish dairy producing herds of each type, respectively.

Maximerande av ekosystemtj?nster i urbana kulturmilj?er: En fallstudie om tr?dval i Pommerska tomten i Mariestad

The purpose of this work has been to explore what ecosystem services a small green area in an urban environment can offer and whether specific trees can be used to maximize regulatory ecosystem services in a cultural-historical environment. Additionally, it investigates whether there is any difference in ecosystem services depending on whether these trees, or trees that better fit into the cultural-historical environment, are used. Through simulations and comparisons with existing trees in Pommerska tomten, Mariestad, Sweden, a pocket park within a national interest area, different hypothetical tree planting options are analyzed and evaluated. To measure ecosystem services, the website My-Tree, developed by the US equivalent of the Department of Agriculture, was used. By inputting data about the tree, such as location, species, vitality, stem diameter, and solar exposure, My-Tree calculates some of the ecosystem services the tree provides.

Att gå en gyllene medelväg. Nio barnbibliotekariers resonemang kring Wahlströms långserieböcker på folkbibliotek

The aim of this masters thesis is to examine how some childrens librarians in public libraries reason about Wahlströms series books. During the 1970s, there was a discussion about the series books, and the general meaning was, among other things, that the books should not be available at libraries. Therefore, we also want to study if the arguments for and against the series books presented today are any different than those presented in the 1970s. For this examination, two methods have been used. We have done qualitative interviews with nine childrens librarians, and in order to find the arguments presented in the 1970s, we have studied the literature regarding the mentioned discussion.

Standardisering av brukarrelaterade indata för energiberäkningar på kommersiella lokaler

In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.

Betets avkastning på olika typer av naturbetesmark : en fält- och metodstudie

AbstractA prerequisite to be able to use semi-natural pastures in an optimal way is knowledge about their conditions and properties. One thing to consider is the amount of herbage mass that can be produced during one season on different types of semi-natural pastures. That knowledge makes it easier to choose which type of animals and how many you are able to have in each paddock to maintain a high biodiversity and achieve the desired production of the animals at the same time.This study was performed in nine different semi-natural pastures around Uppsala. The paddocks were already mapped with regard to different vegetation types. Exclosure cages were placed on previously fertilized, mesic, dry, shaded and wet vegetation.

Good cop - bad cop? : - en jämförelse i ilska och aggression hos polisstudenter och universitetsstudenter

The main purpose of this study was to compare the levels of anger and aggression between male and female Police Academy students (N=106) and male university students (N=100), using 2 psychometric anger instruments; Novaco Anger Scale-1998-S (NAS-1998-S) and Aggression Questionnaire-S (AQ-S). Another aim was to examine if there was a difference in anger and aggression between male and female Police Academy students. Questionnaires were handed out to Police Academy students in Växjö and the result was compared to university students from a previous study by Lindqvist, Dåderman & Hellström (2003). Analyses using a series of Independent sample t-tests showed a significantly lower level of anger and aggression in the Police Academy sample. There were no significant difference in anger and aggression between males and females with the exception of two subscales of the NAS-1998-S and AQ-S; females scored significantly higher on NAS Arousal and males scored significantly higher on AQ Physical aggression..

Nyheternas födelse : En kvantitativ undersökning av källor till lokala nyheter i lokaltidningar

The purpose of this thesis was to study the origin of the local news in local newspapers. Do the news originate mostly from the police, the municipality, from press releases or from the reporters own ideas? We also wanted to find out what kind of content predominated in texts with its origin in press releases respectively the reporters own ideas. Of course we also wanted to find out if there were any similarities or differences between the two studied newspapers.We used a type of constructed week, but with non random selection instead of random. We chose one of each weekday the newspapers were published and studied the news covered in the papers that specific day.

Effects of two different light programs on milk yield, prolactin, IGF-1 and sleep in dairy cows

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Vilka faktorer påverkar ett mjölkföretags tillväxt? : en jämförelse mellan Sverige och Danmark

Dairy farms have during a long time been under pressure and this situation was aggravated during the spring and summer of 2009, when profitability declined to historically low levels. Lower milk price and relatively high input prices have caused Swedish dairy farms great liquidity concerns and profitability problems. For a long time, Denmark has been identified as a leading country for the agrarian development with a leading structural rationalization and willingness to grow. In 2009, it was shown that the Danish agriculture, which is generally more leveraged, has difficulties in maintaining profitability and when market price of land started to fall, the proportion of technically insolvent agricultural enterprises rose dramatically. In light of this prevailing situation, this study highlights differences between Denmark and Sweden with the hope to learn from each other.

EU som demokratifrämjare? : En jämförande studie av Europeiska Unionens demokratifrämjande politik gentemot Makedonien, Kroatien och Turkiet

 In this essay the aim was to investigate how the EU is trying to function as a democracy promoter in three particular countries, the so called candidate-countries Croatia, Macedonia and Turkey. The aim was also to analyze if there exist any differences in how the EU functions in these countries as a democracy promoter with a focus on how acts of democracy promotion is taken place. In order to fulfil the purpose of the essay two questions were addressed, how does the EU perform in promoting democracy in the three candidate-countries Croatia, Macedonia and Turkey? And also, is it possible to identify any differences in how the EU functions as a democracy promoter in those three countries?The method used to fulfil purpose and answering research-questions was qualitative text-analysis.  The results of the study were that the EU does perform in a number of ways to promote democracy in the three countries. The main differences are that the EU is using primarily political tools in Croatia and Macedonia which are channelized top-down and economic tools in Turkey channelized mainly top-down to promote democracy.

Argumentera för den agila metoden : Att stärka argumentationen till beställaren i förespråkandet av agil projektmetodik

Syftet med arbetet är att identifiera svårigheter med att argumentera för den agila projektmetodiken till en beställare. Arbetet har även till syfte att ge rekommendationer på hur en organisation kan stärka sin argumentation för den agila metoden ut mot beställaren. För att uppnå arbetets syfte har den kvalitativ forskningsintervju och en litteraturgenomgång tillämpats. Resultatet visade att svårigheterna är att alla yrkesroller internt inom organisationen inte har en och samma definition över vad den agila metoden innebär. Den nuvarande agila modellen ansågs också av flertalet respondenter inte vara tillräckligt utarbetad.

The overall aim with this study was to examine the impact of health promotion on work related well-being and stress in an industrial company. The focus was on employee experience of and participation in company initiated wellness activities. A quantitative cross-sectional study was conducted in which parts of the Copenhagen Psychosocial Questionnaire (COPSOQ II) were used to examine factors in the psychosocial work environment, and well-being was examined with the Satisfaction with Life Scale (SWLS). In all 303 employees (50 %) responded to the survey.

Att bita den hand som föder en? EU-kritiska parlamentarikers arbete i Europaparlamentet

The study seeks knowledge about the Swedish euro-scepticism and about the work of the Swedish euro-sceptical Members of the European Parliament (MEPs). How do they work in an environment where the norm is to have a positive attitude towards a future federal state of Europe? How do they regard their own situation and possibilities to make a change?The study includes a debate on today's Swedish euro-scepticism as background. My finding about the MEPs? work is that their way of acting in the European Parliament does not distinguish from other MEPs? in large.
