Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)

Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate deciduous forest.

Controlled traffic for grass silage production : an economic evaluation for dairy farmers

The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.

Vattensork och åkersork - skadegörare i svensk fruktodling

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Att utvecklas inom sitt yrke : Om den högre utbildningens inverkan på den erfarna pedagogen

This work is based on qualitative interviews with four educationists who before their university studies lack education in their own field of work. The study aims to explore how higher learning influenced and affected these people. As a theoretical point of view the concept of implicit learning and Aristotle?s epistemological approach was used. The study gives an idea that the concept of knowledge is advanced and can go from practical experience to more theoretical understandings.

En studie om klagomålsbeteende i den virtuella världen

The thesis ?Vi fixar och trixar oss fram till att hjälpa människor? focuses on social work in the field of prostitution and human trafficking in Sweden. Through semi-structured interviews with social workers in the municipalities of Stockholm, Göteborg and Malmö working with persons selling and buying sex, and through discourse analysis, the author analyses the perceptions among these social workers of the relation between human rights, prostitution and human trafficking, and the social work which they conduct.The thesis concludes that although the social workers perceive prostitution and human trafficking and social work in this field as human rights related, they are not explicitly using a human rights based approach in their work.The thesis concludes that the social workers identify several aspects that infringe on the rights of their clients in relation to the human rights principles of Universality, Non-discrimination, Accountability and Rule of law and the principle of Participation and Inclusion. They portray the human rights situation of street based sellers, especially those not being Swedish citizens and those affected by human trafficking, as severe.The thesis concludes that the social workers find several obstacles (legal as well as structural) that diminish their ability to strengthen their clients? human rights situation.

Bostadsgården : att se till de boende vid utformningen av bostadsgårdar - en litteraturstudie kring bostadsgårdens betydelse

This candidate essay is built on literature studies and discusses the meaning of the residential yard along with what you, as a landscape architect, should think about when you are designing functional residential yards. To do this I found it necessary to figure out what it is that makes people step outside their own apartment and out into the city?s public places. The reasons for this are numerous and many times individually affected. Something that plays a role in people?s outdoor life and prevents them from spending time outside is the lack of time, the technique of today and the feeling off insecurity.

Att försvara sitt ursprung - en musikalisk resa i Transsylvanien

Title: Defending one's origin ? a musical journey to Transylvania.A journey to the Transylvanian part of Romania was pursued with the intent to investigate the cultural aspects of the historically and politically rooted set of relations between the Hungarian peaking minority and the majority of the population, the Romanian speaking group. Music pedagogical ambitions within the two cultures were used as reflections of these phenomena. In trying to shed light on my questions and extract the relations between the dominating and the dominated in this specific cultural and social context I have used the central themes of Bourdieu ? capital, habitus and field.

Utvärdering av informationssystem vid företagsförvärv: Synergiers påverkan på informationssystems integrationsroll

The numbers of mergers and acquisitions have increased significantly in the last period of time. Although this popularity for mergers and acquisitions, most of the mergers and acquisitions fail to create value. One explanation to this failure of value creation is, according to several studies, how companies treat integration of information systems in the pre-merger evaluation. The research within the field argues that information system integration should have a proactive role in mergers and acquisitions, meaning that information system integration should support the organizational change and normally be considered in the premerger evaluation. The aim of this thesis is to study issues that affect whether companies choose to consider information system integration proactively, when involved in mergers and acquisitions.

Vad innebär digitalisering av kulturarvet? En ideologianalys av tre svenska digitaliseringsprojekt

This Masters Degree thesis aims at giving an answer to what underlying ideologies are at work in digitizing our cultural heritage. Other questions to be answered are who are benefiting from a digitized cultural heritage and who are not, and what different opinions about digitizing our cultural heritage can be identified. Two studies are made in this thesis, one of Swedish political documents that concern digitizing our cultural heritage, libraries, museums and archives, and the other one is a study of documentation of three Swedish digitizing projects. In the first study three different, but closely associated ideologies are identified, namely a preserving, b giving access and c a mixture of both, and these are shown in a model. In the second study this model is then used to identify the ideologies of one project from each sector of the so called ABM-sector Archives, Libraries and Museums.

Genomisk selektion och uppbyggnaden av avelsprogram hos mjölkkor

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

Gränssnitt, användbarhet och sökmotorer: ett experiment

This aim of this thesis is to measure the effect of the user interface in real searches on the Internet through a small experiment. Theories on web and search usability and psychological factors concerning usability were first explored. Then three interfaces were constructed, one "good" that followed usability guidelines and had multiple search functions, one "bad" that completely disobeyed those guidelines and had only a simple and small search field, and one "intermediate" interface that was a mix of the two. The search field was set to different sizes, with the shortest in the "bad" interface, a medium field in the "intermediate" interface and several long fields in the "good" interface. All three interfaces were then attached to the same web search engine, Altavista.

Selen och incidens av typ 2-diabetes - en systematisk översiktsartikel

Background: Type 2 diabetes is a disease which causes vascular damage, stroke and premature death.Oxidative stress may play a role in the development of insulin resistance and diabetes. Selenium is amineral involved in the protection against oxidative stress, and has been thought to be favorable in theprevention of the disease. However, this has changed since trials observed positive correlationsbetween high selenium levels and incidence of type 2 diabetes.Objective: To examine the studies that investigates seleniums effect on the incidence of typ 2 diabetesSearch strategy: Searches have been done in PubMed and Scopus.Selection criteria: Included studies were human studies in English/Swedish with RCT or cohortdesign with the aim to investigate the correlation between selenium and incidence of type 2 diabetes.Excluded studies were studies whose aim was to investigate the role of selenium in patients withexisting diabetes. Studies regarding pregnant women, animals or children and with in vitro design werealso excluded. Of the studies found in Scopus where MeSH terms were available, the ones who did notinclude relevant terms were excluded.Data collection and analysis: Studies were collected according to the aforementioned criteria.
