Storskaliga markinvesteringar - framgångsrik utvecklingsstrategi eller hot mot lokala försörjningar? : En fallstudie av Kalangala palmoljeprojekt i Uganda

Education systems face a number of challenges regarding social justice, diversity, difference, and inclusion and membership for all students in the groups that schools create. This invokes questions of how well these challenges are met in curricula and teaching materials. Through discourse analysis of eight Swedish geographical textbooks, this essay aims to seek out the perspectives surrounding difference within the subject of geography. It concludes that the idea of fixed homogenous cultures as meaningfull in differentiating among people dominates throughout the latter half of the 20th century and during the last decade. In addition, it concludes that the discourse surrounding diversity in Swedish geographical teaching materials mainly has a binary liberal view of plurality focused around tolerance.

The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

Jordlöparfaunan i bestånd av contortatall (Pinus contorta) och svensk tall (P. sylvestris) 1987 och 2010

In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity. Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase. In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.

Lärande genom lärorika och lustfyllda metoder i dagens förskola. : En kvalitativ studie om pedagogers reflektioner kring deras dagliga arbete med barns lärande

I want to investigate different preschool teachers' views of their daily work in terms of the diversity of children and learning, and the methods and strategies of preschool teachers use in their everyday lives, to meet every child's individual needs. I also want to investigate preschool teacher?s perceptions of children's social skills as this is included in the pre-school assignments relating to a favorable social environment for all children.To find this out, I have compiled three issues.What are the views interviewed preschool teachers to learning and different lustful methods that make the educational activities meaningful for all children?? What pedagogical strategies do preschool teachers to respond to the diversity of children?? What opinions have interviewed preschool teachers about children's social interaction with other children in preschool?The conclusion is:all children are different and learn in different ways. Teachers have the responsibility to ensure every child's development and adapt the business to the children's level and needs in a way that could inspire children to learn new skills. It is teachers' responsibility to provide children with good opportunities to express their views and feelings.

Förändring av grönområden i Västerås tätort det senaste seklet : Konsekvenser av att grönområden förändras

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal

There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.

Genetic study of cryptorchidism in Swedish Icelandic and Standardbred horses

Samodling är en odlingsmetod som kan användas för att förbättra dagens odlingssystem. Metoden innebär att två eller flera kulturer odlas tillsammans under en större del av växtsäsongen. Samodling kan användas på flera olika sätt för att förbättra odlingsförhållandena för antingen huvudgrödan eller hela odlingen. Den har en bevisad effekt på olika skadegörare och kan minska angreppen i odlingen. Samodling kan även användas för att minska ogrässpridningen, förbättra mikroklimatet, samt öka antalet maskar och naturliga fiender i odlingen.

Spridningsmönster och potentiella spridningsytor hos invasionsarten stor bockrot (Pimpinella major) i Tullgarns naturvårdsområde : ett framtida problem för områdets diversitet?

An organism that is transferred from one place to another, causing major problems to the native species is termed invasive. Its natural dispersal across barriers may have been prevented but as man has turned able to rapidly travel all over the world organisms are brought to sites where they were never before observed. Adding the increasing global warming organisms may find it necessary to move around even further. This might cause major disturbance to the biological diversity, and hybridization and homogenization is one of many scenarios that could disturb the native diversity. In Sweden more that 2/3 of all alien plant species have been introduced to disturbed areas and the major introduction mechanism is gardening.

Avelsarbete med mjölkproducerande getter ? fokus på Norge och Frankrike

The main part of the goats in the world is located in developing countries, whereas active breeding programs are mainly restricted to Northern America and Europe. Goat milk can be processed to several products and goat cheese is the main product. An organized breeding program is carried out in France and Norway but is not present in Sweden. Important selection traits for milk producing goats include milk, protein and fat yield along with protein and fat content. Functional traits have been more important the past years and they have large economic importance for the farmers.

Beskrivning och analys av superovuleringsresultat och andra fertilitetsregistreringar vid Nötcenter Viken :

Recording and analyses of superovulation results and fertility records at the nucleus herd Viken The development of different reproductive technologies aim at increasing the number of progeny per individual parent, and in that improving the possibility of genetic progress. One technique, embryo transfer, have facilitated genetic dissemination and shortened the generation interval also in females. Nötcenter Viken is a company that run embryo collection and embryo transfer in the breeds Swedish Red and Swedish Holstein. It is located outside Falköping. Information is continuously gathered about cows tested at the nucleus herd.

Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL

This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Det levande biblioteket ? retorik kring fördomar och möten. En argumentationsanalys i relation till folkbibliotekets mångfaldsuppdrag.

The living library started in Denmark at the festival of Roskilde in 2000. It was initiated by the youth organisation ?Stop volden? (?Stop the violence?). Since 2005 the idea of lending a human being who represents a prejudice has also become a practice in a few public libraries in Sweden. I found it interesting to analyse the living library in relation to the mission of diversity in the public library.

Diskurser om kultur under EU-rationalisering: En historisk policyanalys.

The aim of this master?s thesis is to study the discourses on culture as developed by EU Commission. The method applied is a discoursebased historical analysis, where analysis of arguments and metaphors are functional to the enlightening of the construction of discourses within EU cultural policy. EU official documents constitute the empirical material studied. The theoretical framework of the thesis draws upon cultural public sphere theory as well instrumentalist cultural policy research.

Våtmarker i urbana miljöer : växtgestaltning och planering

The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability. Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do. The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.
