Insect pollination of oilseed rape

Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. To determine the value of enhanced crop pollination as a means of ecological intensific

Effects of agricultural intensity and landscape complexity on plant species richness

Jordbrukets intensitet har under de senaste decennierna ökat genom effektiviserad teknikanvändning och ökade insatser av pesticider och växtnäring. Detta har inte bara lett till ökade skördar utan även till negativa konsekvenser för den biologiska mångfalden i jordbrukslandskapet.I denna studie inventerades förekomsten av kärlväxter i 160 höstvetefält (Triticum aestivum L.) på 32 gårdar i Uppsala-

International Trade and Labor Market Integration of Immigrants

We examine if international trade improves labor market integration of immigrants in Sweden. Immigrants participate substantially less than natives in the labor market. However, trading with a foreign country is expected to increase the demand for immigrants from that country. By hiring immigrants, a firm may access foreign knowledge and networks needed to overcome information frictions in trade.

Impacts of Clear-Cutting of a Boreal Forest on Carbon Dioxide, Methane and Nitrous Oxide Fluxes

The 2015 Paris Agreement encourages stakeholders to implement sustainable forest management policies to mitigate anthropogenic emissions of greenhouse gases (GHG). The net effects of forest management on the climate and the environment are, however, still not completely understood, partially as a result of a lack of long-term measurements of GHG fluxes in managed forests.

Life Cycle Assessment of an Office Building Based on Site-Specific Data

Life cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building. The goal of this project was to calculate the environmental releases for a whole office building and investigate the contribution in terms of environmental impact for different parts of the building, as well as the impact from different stages of the life cLife cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building.

The Origin and Destination Principles as Alternative Approaches towards VAT Allocation : Analysis in the WTO, the OECD and the EU Legal Frameworks

When it comes to determining the jurisdictional reach of VAT, two principles are used by the OECD, EU policy makers and scholars, namely, the origin principle and the destination principle. These principles can mean different things. One problem is that different constructions thereof can result in confusion in the communication between legal actors and, more importantly – in different legal outco

Self-compatible blueberry cultivars require fewer floral visits to maximize fruit production than a partially self-incompatible cultivar

Effective pollination is a complex phenomenon determined by the outcome of the interaction between pollen transfer and a plants' pollinator dependency, yet most studies investigate pollinator effectiveness without consideration of plant mating system differences. We investigated pollinator effectiveness in three types of blueberry that differed in their degree of pollinator dependency as measured

Karriär och profession. : Om positioner, statushierarki och mobilitet inom socionomyrket.

Samhällsreformer och utvecklingen inom den svenska offentliga sektorn har omformat förutsättningarna för socionomyrket och andra professioner samt förändrat socionomernas arbetsområde. Jag har använt begreppet karriär för att undersöka förändringar inom socionomprofessionen, eftersom det ger ett perspektiv för att belysa stabilitet och förändring samt kan fånga både externa och interna krafter i pSocietal reforms and development within the Swedish public sector have reframed the prerequisites for social workers, and other professions, and changed the area of work practice. I have used the career concept in order to investigate professional change because it provides a conceptual lens to illuminate stability and change and it captures both external and internal professional processes.
