Rosenlunds bankar : Erosion och förändring sedan 1960

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

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.

På vilka grunder väljer föräldrar skola?

The study is made in Nacka, a suburb of the capital of Sweden, Stockholm, and focuses on ?the parental school choice" that takes place when children start in first grade at the age of six. New differences in the number of pupils attending various municipal schools have appeared after reforms in the early 1990s giving parents free choice of elementary school for their children. Some schools are located in areas where most children have a middle class background, while others are placed in less attractive surroundings where the parents have a lower educational status, and are more often immigrants. Parents living in the latter kind of surroundings can now send their children to schools further off, but located in more attractive areas. This leads to some schools get an increasing number of pupils and others gets a decreasing.

Järnvägsstationer i Litauen 1861-2011 : Namngivare, namnbyten och språkbyten genom 150 år

The names of railway stations and halts along the earliest railway lines on Lithuanian territory have been studied, i.e. along those railway lines built between 1861 and 1873. Especially, attention has been drawn to names that are not obvious regarding the geographical location of the station or halt. Some 50 percent of the names are showing some kind of irregularity in this respect. Most common (about 30 examples) are stations or halts that are serving a population centre situated at some distance from the station, but still bearing the name of that population centre.

Den ofrivillige nationalisten : En komparativ studie av nationalism i Sverige under finanskrisen 2008-2011 utifrån dagspress

Mass communication today stands for a great number of information in the developed welfare state of Sweden. This was also the case during the social and economic financial crisis in 2008-2011. At this point, the majority of the population chose to turn to the newspapers to look for further information. This essay seeks, in a comparative and theoretical way, and with the help of two theories of nationalism, to understand how the Swedish culture and tradition can be ex­plained via newspapers, and in what way these portray nationalism. What it also sets out to in­vestigate further is what kind of impact it might exercise over the population in its position as one of the leading providers of information.

Varning för stereotyper : en studie med syfte att urskilja och diskutera identitet

Through this thesis I aimed to further investigate how we can adapt our western and modern views of masculinity and femininity in an ancient population, here on the Pitted Ware population from Ajvide on Gotland. A questionnaire survey was used to compile the modern view of masculinity and femininity. This modern view was then compared with patterns which had become visible through statistical processing of the burial gifts found on Ajvide. The thesis is mainly focused around the concept of gender, but age and status have also been discussed. Through several performed correspondence analysis, it became clear that the current view of male and female differed from the one that became visible in the archaeological record.

Vildsvinsskador inom jordbruket : hur stora är förlusterna?

Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.

Jakten på det svunna Löddeköpinge. En studie av hälsa, karakteriserad av artros, kroppslängd samt trauma, i det medeltida Löddeköpinge

The purpose of this study is to assess the state of health of the individuals living in Löddeköpinge during the middle ages, whose remains were excavated by Chintio, H., 1975-80. The location is thought to have been a trading community that ceased to flourish towards the end of the Viking age. The main focus of the essay is to examine the occurrence of osteoarthritis (sv. artros), trauma, and analysis of stature, in order to understand population health during this time period. Osteoarthritis has never been researched in Löddeköpinge and the analysis showed that, of the 60 skeletons examined, 68,3% demonstrated some change in the skeletal joints, which is much higher than in the comparative material obtained from Lund and Sigtuna.

Förvildade husdjur : möjligheter och hot

Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.

Utvärdering av Group Development Questionnaire-interventioner på svenska arbetsgrupper

Arbetsteam har blivit en allt mer vanlig tillämpad organisationsform på dagens arbetsplatser. Att utforma bra metoder för att stödja arbetsgruppers utveckling är därför av stor vikt. Group Development Questionnaire (GDQ) är en metod framställd för att arbeta med grupper ur ett utvecklingsperspektiv. Denna studie utvärderar resultaten av GDQ-interventioner som genomförts på tolv svenska arbetsgrupper, i syfte att undersöka om positiva förändringar skett i grupperna. Resultaten visade inte på några större signifikanta förändringar i gruppernas fasutveckling.

Pilot study: influence of the Samoan dog population on visitors

A range of public health and animal welfare problems has been shown to be associated with free-roaming dogs. With a high density of free-roaming dogs and with a major tourism industry, Samoan tourists are likely to be influenced by the presence of the dogs. The tourists are mainly from the Oceanic region; with New Zealand and Australia as the biggest contributors. The aim of this study was to examine the potential impacts of dogs on visitors to Samoa. A questionnaire was handed out to 281 visitors all over Samoa, collecting opinions and information on visitors? experiences and behaviour regarding the Samoan dogs.
