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.

Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet

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.

Befolkningstillväxtens mosaik i Umeå kommun

The purpose of this thesis is to present and analyze population developments within Umeå municipality during the period 1992 to 2012. The study also aims to discuss growth trends presented in previous papers to seek common factors and get a deeper understanding.Data for 1992, 2002 and 2012 on a sub area level supplied by Umeå municipality was used. The study shows a continued positive development across almost all sub areas, but a differing growth rate from centre to periphery, and also a diversified medium age among the inhabitants.While the city center continues to have the highest growth of population during the studied years, a recent trend seems to point to a growing popularity to settle in the outskirts of the municipality, primarily near the coast..

Bostadssektorns koldioxidutsläpp

Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.

Genomisk selektion inom köttraser

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.

Är den starkt växande vildsvinspopulationen ett hot mot tjäderns reden?

This case study is based on a previous documented method of manufacturing artificial nest containing pre-colored hen eggs. This method is going to be used to find, if the wild boar population, which is growing in number, is a threat to the capercaillie population.  In comparison to the wild boar population, the capercaillie population is diminishing in different parts of Sweden.  In order to find out if they are affect by each other, the case study was carried out during the months of April to May 2009. 100 artificial nests were placed out on various locations on the Södertuna estate just in the outskirts of Gnesta. The unique aspect of this study is that a fenced environment to keep out wild animals is used to conduct this study, which has been previously known to be free from wild boar, but the area outside has sittings of wild boar. So to fully understand how this affects the capercaillie population, 50 of the nests were placed outside the fence area, while the other 50 nests were placed inside the fenced area. The sites were visited on two separate occasions, and were noted of the changes inside and outside the fenced compounds.

Gäddan & fisket i Ringsjöholm : en osteologisk metodstudie i säsong & bevarande

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

Öppenhet och kostnad för eget kapital: En studie på den svenska marknaden

Previous research has discussed how voluntary disclosure relates to the cost of equity capital. Theories of estimation risk support a negative association between disclosure and cost of equity capital, as empirically documented by Botosan (1997) among others. In this Bachelor thesis we investigate whether such a relationship exists on the Swedish capital market. Using the CAPM to estimate the cost of equity capital and a disclosure index based on Aktiespararen?s annual evaluation of corporate disclosure, we test a model where disclosure explains cost of equity capital.

Etnisk diskriminering på den svenska arbetsmarknaden

This thesis examines the Swedish labour market with a focus on the immigrant part off the population. There are big differences between the immigrant and particular non-European immigrant part off the population and native Swedes. In the first part off this thesis I will show that immigrants in Sweden have a higher rate of unemployment, lower rate off employment, lower wage incomes, higher risk off unemployment and are overrepresented in low skilled, low status jobs. Even when controlling for different factors such as education level, knowledge in the Swedish language, age etc. a big gap remains.

Den öländska älgstammens förvaltning : en granskning av förvaltningsplanerna och jaktens upplägg

To Swedes in general and, to hunters in particular, there is a great interest for moose (Alces alces), witch is Sweden?s largest deer species. In the province of Öland (Sweden?s second largest island) the local people show a great interest for the moose existence, both for consumptive (hunting) and non-consumptive use (tourism). This became apparent in 2002 when the moose hunters on Öland voluntary agreed to temporarily postpone the moose hunt on the island.

Regionala och sociala skillnader i hälsotillstånd : En jämförelsestudie av Danderyd och Rinkeby

Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County.    The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review.      The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.

Seroprevalens av antikroppar mot Encephalitozoon cuniculi hos friska tamkaniner :

The aim of this study was to determine the prevalence of antibodies against the intracellular protozoan Encephalitozoon cuniculi in healthy pet rabbits. Encephalitozoonosis is an important differential diagnosis to ascending infection with Pasteurella multocida in the ears since a common symptom is vestibular syndrome. Samples were collected from healthy rabbits that were brought to an animal clinic in Stockholm for some kind of prophylactic procedure. The samples were analysed by an India-ink Immunoreaction test / Carbon Immunoassay. Of 106 rabbits 7 (6.6%) were seropositve.

Den licensierade vargjaktens betydelse för vargstammen

In October 2009, a new decision was made concerning the administration of predators which resulted in a new wolf policy in Sweden. This meant that the wolf population now should be limited to 210 individuals by harvest. The new policy also recognized that the public acceptance of this species must increase and the genetic status improved. In the 17th of December a decision was taken by the Swedish parliament that it should become legal to hunt wolves in Sweden. The wolf hunt resulted in debate on a large scale amongst people, some thought of it as a good decision while others thought it was wrong.

Hur har utvecklingen av andelen pension?rer i befolkningen p?verkat Tysklands arbetskrafts storlek fr?n 2000 till 2022?

Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.
