Food security can be defined as stable access to food of good nutritional quality. In Sub Saharan Africa access to food is strongly linked to local food production and the capacity to generate enough calories to sustain the local population. Therefore it is important in these regions to generate not only sufficiently high yields but also to reduce interannual variability in food production. Tradit

Changes to the carbon cycle in tropical forests could affect global climate, but predicting such changes has been previously limited by lack of field-based data. Here we show seasonal cycles of the complete carbon cycle for 14, 1ha intensive carbon cycling plots which we separate into three regions: humid lowland, highlands, and dry lowlands. Our data highlight three trends: (1) there is differing

This paper focuses on the relationship between PTAs and political uncertainty. Further, it analyses if the AMU has managed to create a dampening effect and thereby maintain the intratrade flows during the Arab Spring. This can be interpreted as the cushion effect. Previous literature has not addressed this unique approach. This could be due to the belief of AMU being an inefficient trade agreement

The purpose of this thesis is to demonstrate how nonviolent methods can be successfully used in struggles against repressive regimes. This is done by examining two cases of uprisings in the Arab Spring, Egypt and Tunisia. Drawing from theories on nonviolence, mainly Gene Sharp; five elements that are considered favourable for nonviolent struggles has been selected for the analysis. The methodology

The aim of this study is to contribute to the existing literature on co-creation in investigating consumers’ motives for participation on the one hand and possible effects of this participation on brand knowledge on the other. It thus provides a link between co-creation, motivation, and branding literature. A constructionist ontological stance and interpretive epistemology led us to the research p

Syftet med denna uppsats är att undersöka effektiviteten av GDPR som ett verktyg för att skydda arbetstagare från negativa konsekvenser som kan uppstå i samband med algoritmisk arbetsledning. Algoritmisk arbetsledning är ett allmänt förekommande fenomen speciellt i plattformsekonomin, som avser användningen av automatiserade medel för att styra arbetstagare i utförandet av det dagliga arbetet. AutThe purpose of this thesis is to examine the effectiveness of the GDPR as a tool for protection for algorithmically managed workers in light of the standard of protection offered for working conditions in the EU. Algorithmic management refers to the use of automated means to direct, sanction and evaluate workers without human involvement, and it is an especially prevalent phenomenon in the platfor

Budburst models have mainly been developed to capture the processes of individual trees, and vary in their complexity and plant physiological realism. We evaluated how well eleven models capture the variation in budburst of birch and Norway spruce in Germany, Austria, the United Kingdom and Finland. The comparison was based on the models performance in relation to their underlying physiological as

Understanding the relationship between photosynthesis, net primary productivity and growth in forest ecosystems is key to understanding how these ecosystems will respond to global anthropogenic change, yet the linkages among these components are rarely explored in detail. We provide the first comprehensive description of the productivity, respiration and carbon allocation of contrasting lowland Am

The formation of industry standards for environmental issues and corporate social responsibility is gaining acceptance but the number of successfully implemented programs are few. On an individual level companies have for some time applied company standards or codes of conduct. But on a collective level cooperation seems much more difficult. Although from an economic point of view there are clear

My thesis examines the discourse and social practices of the Swedish Armed Forces in Afghanistan. The discourse analysis is used both as a theory and method and takes inspiration from Focault, Laclau, Mouffe and Fairclogh. The view on social relations and gender is that they are constructed through social interaction. The purpose is to describe and illuminate discourses and social practices which

Anonymous forms of non-art photography have received a great deal of attention in recent years. Museum exhibitions and published compilations of what is commonly referred to as ‘vernacular photography’ have appeared regularly since the late 1990s. An interest in photographs produced by anonymous amateurs is further reflected in the growing popularity of collecting snapshots that have been lost or

The thesis aims at supplementing a critique of the existing international instruments, regional responses and national legislation of the Arctic related to marine environmental protection. With this aim in view, the thesis satisfies its objective by proposing a Bipartite “Arctic Council” acting as a conglomeration of the Arctic States and the Flag States with a hybrid “Arctic treaty”, which is an

Unlike the Quebec classification system, which is based primarily on pathoanatomy, a new Swedish classification system is based on the site of functional impairment and disability. A prospective study was performed on 85 patients with whiplash-associated disorders grade II according to the Quebec classification. The patients were examined 3-36 months following trauma. A team of professionals with

Studies from our and other laboratories have over the last 2 years implicated the existence of multipotent progenitors (MPPs) with combined granulocyte-macrophage, B cell, and T cell potential, but little or no megakaryocyte-erythroid (MkE) potential in the adult bone marrow Lineage (-)SCA-1 +KIT+ (LSK) compartment of multipotent stem and progenitor cells. The evidence for the existence of LSKCD34

Almost three out of four EU citizens live in urban areas. Knowledge on the city’s environmental structure and capabilities is needed as urbanization is expected to continue. In this study, eight indicators on urban ecosystems condition (ECIs) were quantified for 305 EU cities (>100.000 inhabitants). A composite indicator (CI), based on the ECIs, indicated differences between northern and southern
