Abstract Rivers deliver substantial amounts of carbon (C), nitrogen (N) and phosphorus (P) to estuaries, but the effects of these inputs on the ecosystem depend on the degree to which the nutrients are bioavailable. The nutrient bioavailability is poorly known in northern regions of Scandinavia where most of the nutrients are organic. To simplify the measurements of nutrient bioavailability and
Many companies today strive to reduce their environmental impact. A potential strategy to reduce CO2 emissions is horizontal cooperation between actors on the same level of different supply chains. The strategy opens for cooperation, in for example such non-core activities as distribution and transportation, between companies with a competitive relationship. Larger transport networks increase the
Arctic ecosystems are among the most vulnerable to climate warming due to large-scale changes in temperature, followed by altered community structure. Northern birds are subject to population reduction and range contraction in Europe and many mountainous birds show negative trends. Even if global trends are clear, local studies on a detailed level are needed to obtain more information on possible
Due to the depletion of earth’s resources and the growing concern of electronic waste it is important to extend the lifespan of electronic products. Consumers often have the perception that re-used and remanufactured products are of lesser quality than new counterparts. This study aims to evaluate if a more comprehensive sustainability certification scheme for electronic products, covering criteri
Open data is broadly expected to generate innovation and economic value for both the public and private sector. Though the diffusion of open data has kept a fast pace, knowledge of visualisation and points of access of open data remains low. Moreover, literature of the private-sector application of open data is still scarce. The first objective of this thesis is to increase the knowledge about the
Utvecklingen av svensk konkurrenslagstiftning började i början av 1900-talet. Efter en lång period av motioner, debatter och utskottsrapporter skapades 1925, "Lag om undersökning angående monopolistiska företag och sammanslutningar". Uppsatsen innehåller en översikt av lagens utveckling. Uppsatsen börjar med att lyfta fram några motioner som skrevs mellan 1910 och 1920. Dessa visar den
Speech Emotion Recognition (SER) opens up the possibility to collect opinions from people in channels that have not be conceivable before, such as youtube videos, podcasts or phone calls. SER is becoming more advanced, and the SER models that have been published recently are reaching accuracy-results well beyond state of the arts. However, SER is not a simple task and it is most common that the mo
Den svenska staten bedriver affärsverksamhet via ett femtiotal företag av vilka staten äger minst 50% av företaget i 43 av fallen. År 2007 antog den svenska regeringen en rad nya riktlinjer gällande hållbarhetsrapportering för dessa företag. Dessa nya riktlinjer skulle tas i bruk från och med räkenskapsåret 2008. Hållbarhetsrapporteringen, dvs. den icke finansiella rapporteringen av dessa svenska
This study begins in the understanding of sustainable development as a complex matter open for interpretation, and continues in the notion that different dimensions of sustainability create different values that have different goals; meaning that they will sometimes unite, and sometimes collide and lead to trade-offs. The aim for this study is to add to the understanding of this matter through an
