Fri utfodring av halm som strategi för att förhindra stereotypier hos uppbundna kvigor :

At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle. The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals. Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.

Undersökning av självspridning av contortatallen i norra Sverige

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

?där var jag ett barn, nu känner jag mig som en man? - En kvalitativ studie om ensamkommande barns sociala situation och identitetsutveckling

The purpose of our research was to explore the social situation of unaccompanied children. We also aimed to reveal the relation between their social situation and their identity development. The overall purpose were to describe their social situation, the value of significant others, how different languages influence their identity development and finally how their origin affects their future dreams.In order to achieve the best result in our research a qualitative method was used. This was based on qualitative interviews and was disposed around a very loose set of questions in order to let the interviewees lead the way. The analysis of the result was conducted on the basis of a set of theories and concepts in order to understand the identity development.

Från Rio via Kyoto, till Marrakech. Hur har rättviseproblematiken tolkats i anpassningsdiskussionerna?

Global climate change is one of the greatest challenges in our history. As the average temperature is rising due to anthropogenic emissions, impacts such as floods, droughts and hurricanes, affect the lives of millions of people. Though the least developed countries are least responsible for emissions, they are the worst affected. This thesis focuses on environmental justice in the adaptation discourse. By outlining the adaptation discourse from the United Framework Convention on Climate Change principles, to the Marrakesh Accords, via the Kyotoprotocol my ambition is to analyse how environmental justice has been interpreted in relation to the adaptation discourse.

Kvantitativ studie om knappsatsdesign och knappstorlekars påverkan på träffsäkerhet

A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.

Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Gud, magin och vetenskapen : En analys av August Strindbergs Inferno

This literature review aims to investigate, expose and explain August Strindberg's religious position in his partly autobiographical work Inferno, published in Swedish in 1897, in relation to Peter Berger's socialization theory. Strindberg says in the beginning of Inferno that he goes from being an atheist, occultist and Swedenborgian to finally return to his ancestral religion, Christianity. This is questionable, as Strindberg seems to be religious in its atheistic era, and occultist during his Christian period. Strindberg's own religious views seem not always match what he portrays, compared to what he writes in his correspondence and diary entries. This literature review aims to highlight the influences of Strindberg affected to clarify his religiosity which is implicitly and explicitly depicted in Inferno.

Regeln som splittrar - Om barnfamiljer och regeln om uppehållstillstånd före inresa utifrån internationella konventioner och svensk policy

Swedish migration law states that a person who wants to seek a residence permit based on family ties has to apply from the home country. This essay applies to cases when families that live in Sweden have to come apart when one parent has to return to the home country to seek a permit to which he or she is entitled.The rule causes families unnecessary suffering. This essay analyzes the reasons behind the rule and argues that it is compatible neither with Swedish policy of children's rights and gender equality nor with the international conventions that have been ratified.Furthermore, it is investigated whether the migration authorities act in compli-ance with the intentions behind the law. It is concluded that the Migration Board, despite their own critique of the rule, makes an unnecessarily restrictive interpre-tation. This results in a situation where no one takes responsibility for the conse-quences for the affected families.

Idiopatisk epilepsi : en fallstudie

Epilepsy is a common neurological condition in dogs, being a common reason for death in the statistics from the insurance company Agria in Sweden. Among the different types of epilepsy, idiopathic epilepsy (IE) is the most common and is characterized by the fact that a veterinary examination does not reveal a cause for the seizures. This study has been conducted through studies of medical records and interviews with dog owners. From a total number of 103 dogs that were neurologically examined for seizures, 42 dogs met the inclusion criteria, being classified as having idiopathic epilepsy. When the study was performed, 28 dogs had died, while 14 were still alive.

Lean för kortare väntetid till strålbehandling : Förbättringsarbete och enkätstudie hur det påverkar arbetsmiljön

The aim of the study was to explore the methods used in horticultural therapy gardens in rehabilitating people suffering from fatigue syndrome. Nine horticultural therapy gardens were contacted of wich three chose to participate. Using case study as method e-mail interviews was carried out with the participants about their establishment and what kind of theories they based their methods upon. The material collected from the interviews was complemented with additional data from the establishments web pages and information pamphlets. Collected data was processed trough content analysis and then formed as background for the development of a program theory for horticultural therapy.

Skogsbränsleuttag vid förstagallring och dess påverkan på beståndsutveckling : simulering i Heureka med olika skötselprogram

Stands where pre commercial thinning has been ignored or inadequate often tend to have high stem density and low average diameter when they reach heights of thinning. In such stands, it can often be expensive to do a conventional pulpwood harvest as a first thinning. This study investigates the development of the stands and the economic outcome of forest fuel extraction, or a combined harvest as alternatives to the ordinary pulpwood harvest. Simulations in Heureka StandWise were performed for two thin and dense stands, which were constructed by data from the Swedish National Forest Inventory. The simulations show that the extraction of forest fuel in first thinning at an early stage can provide higher net revenue compared to conventional pulpwood harvest at the same time or later.

Börsintroduktioner : En eventstudie av variationer mellan introduktionskurs och öppningskurs hos börsintroduktioner på Stockholmsbörsens O-lista åren 1995 till 2005.

Denna studie har som syfte att undersöka den svenska IPO-marknaden under åren 1995-2005. Studien undersöker ett fenomen som är frekvent förekommande i samband med börsintroduktioner. Fenomenet kallas underprissättning och med begreppet menas den skillnad i pris som uppstår mellan en akties introduktionspris och dess stängningskurs första dagen den handlas publikt på en aktiebörs. Underprissättningen kan ses som potentiellt kapital som ett företag går miste om. Detta på grund av att aktiens stängningskurs i viss mån representerar vad investerarna verkligen var villiga att betala för en aktie.

Utvärdering och mätning av resultat och effekter av idrottssponsring : - en explorativ studie om hur Vattenfall utvärderar och mäter sin skidsponsring

Idrottssponsring är den marknadsföringsmetod som växer snabbast på marknaden. En organisation som har anammat denna marknadsföringsmetod och lagt ner stora resurser genom att expandera sin skidsponsring, är det statligt ägda elbolaget Vattenfall. Att mäta och utvärdera effekter och resultat av genomförda sponsringssatsningar har visat sig vara en utmaning. Då det råder brist på relevanta utvärderings- och mätmetoder.Med denna explorativa studie var avsikten att undersöka och beskriva hur organisationen Vattenfall utvärderar och mäter effekter av sin skidsponsring. Vidare hade vi för avsikt att ta fram ett kompletterande mått för att kunna mäta och utvärdera resultatet och effekten av Vattenfalls skidsponsring.

This includes the help and support that they have received and also what barriers to care they have experienced during the transition back to everyday life. The theoretical perspectives of this study are social identity and stigma theory. This study was performed using a qualitative method and includes six individual interviews with active duty officers within the Swedish armed forces.

Inuit Circumpolar Conference, en till synes avvikande NGO - En fallstudie av en ursprungsbefolknings organisering kring miljöfrågor och deras sociala och kulturella rättigheter

With ever-increasing environmental problems in the world, I have with this thesis aimed at studying how the Inuit people of the Arctic organize themselves around the issue of environmental degradation. In focus for this thesis is the organization Inuit Circumpolar Conference (ICC), an NGO that focuses on saving and protecting the social and cultural rights of the Inuit people, along with the environment in the four arctic regions. This aboriginal population has a strong connection to the environment they dwell in, as the area serves as a source of income and nutrition as well as an historically important place for their culture.I will in this thesis primarily investigate the methods of operation amongst NGOs, as well as their ability to influence and interact with the UN. These are three concepts that I, as a hypothesis, considered to distinguish ICC from other NGOs. With help from three theories about NGOs, I conclude that certain central elements of ICC differ from the average NGO, making ICC a new kind of actor in global politics..
