Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?
The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.
Undersökning av förekomst av okända virus hos svenska fjällrävar med encefalit :
The artic fox is under threat of extermination in Europe. The population decreased strongly at the beginning of the twentieth century because of intensive hunting. The artic fox was placed under protection by law 1928 in Sweden but despite this the population has had difficultly to recover. This can depend on several reasons, but the main threats are shortage of food and competition from the red fox. Along with Norway and Finland, Sweden has carried out a project called SEFALO (Saving the Endangered Fennoscandian Alopex lagopus), whose objectives were to prevent continued decreased populationnumbers and through, for example supplementary feeding, help the population to recover.
Hultsfredsfestivalen : Hur ett evenemang kan inspirera, påverka och utveckla en ort.
Purpose: The purpose with this study is to clarify what importance a co-occurrence event can have on a smaller town, and also what positive and negative consequences it can have on the town seen from a social, economic and political aspect. I will also look at what magnitude the festival have on the local commercial and industrial life and how it affects those who live there. I will also determent how the moving of the festival might come and affect the local businesses, the local population and the community it-self.Method: I will thorough-out this study work with qualitative research methodology. I will there-for process the empirical data that will be collected and used for this study from a qualitative research methodology point of view. I will likewise go through with two deep-going interviews with people well familiar with the subject to increase and strengthen the validity of my study.
Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?
Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.
Effektivitet i team : omsorgsgrupper jämförda med andra svenska arbetsgrupper från en större population
The aim of the study was to look at the differences in groups in Karlskrona Kommun in comparison to a larger population of work-groups in Sweden. The instrument used was the Team Diagnostic Survey developed by Ruth Wageman, J. Richard Hackman and Erin Lehman (2005) in order to diagnose the strengths and weaknesses in work-groups, as well as explore the group?s behaviours and effectiveness. The results show that there was a significant difference between the Karlskrona Kommun groups and the larger population of Swedish groups in the following areas: stable, clarity, challenge, diversity, whole task, resources and availability..
Kartläggning av symtom på depression hos patienter med hjärtrytmrubbningar
Cardiac arrhythmias and heart diseases can result in a limited performance capacity which could lead to anxiety and depression. Objective: The aim of this study was to investigate the prevalence of symptoms of depression among patients with cardiac arrhythmias. The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

Kartläggning av depressiva symtom hos patienter med arytmi
Objective: The aim of this study was to study the prevalence of depression among patients with arrhythmia, and to investigate if there was any gender difference in the study population regarding depression. Furthermore, differences considering depressive symptoms between patients with arrhythmia and the general population were to be investigated. Method: The self-rating scale MADRS-S was distributed during two weeks to 24 patients with arrhythmia. Twenty-one patients completed the study. Results: 28.5 % of the participants showed symptoms of some level of depression.
Effekt av biotopvård på öringpopulationen i två vattendrag
I have done a follow up study of the restoration of two rivers, Röälven and Grundan, in order to evaluate the effects of the restoration on the endemic population of trout. Both rivers have been used for timber floating during many years throughout the 20th century, and because of this, had all obstacles such as rocks and wood parts removed. In 2004-2005 both rivers were restored, and rocks and wood were put back into the rivers. Spawning grounds were created and boulder dams were constructed to promote the streaming water. The result showed that the trout population of both rivers increased after the restoration, but also that the trout population of Röälven increased more than that of Grundan.
Den sociala rörligheten bland frälse- respektive skattebönder i Björklinge socken 1786?1848
Between 1750 and 1850 the population of Sweden doubled. The increase was very unequally distributed among the different social groups of the rural population. The number of peasants grew very little, while the numbers of the landless (crofters, bordars etc.) more than quadrupled. This study examines whether Christer Winberg's thesis of the landless growth can be applied to Björklinge parish in Uppland. Winberg believes that it was mainly children of tenant farmers who became landless.
Hållbart nyttjande av vattenresurser på Gotland : vision och verklighet
Fresh water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.
Balis trädgårdar
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Local stakeholders? willingness to conduct actions enhancing a local population of Grey Partridge on Gotland ? an exploratory interview study
The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.
