Fire at the dry southern margin of the Amazon rainforest could have major consequences for regional soil carbon (C) storage and ecosystem carbon dioxide (CO2) emissions, but relatively little information exists about impacts of fire on soil C cycling within this sensitive ecotone. We measured CO2 effluxes from different soil components (ground surface litter, roots, mycorrhizae, soil organic matte
In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label
Climate warming has caused the seasonal timing of many components of ecological food chains to advance. In the context of trophic interactions, the match–mismatch hypothesis postulates that differential shifts can lead to phenological asynchrony with negative impacts for consumers. However, at present there has been no consistent analysis of the links between temperature change, phenological async
Global biogeochemical cycles and their interactions are an important parts of climate research. Investigations during the last decades emphasize the key role of diatoms – siliceous phytoplankton – in the silicon (Si) cycle as they are important carbon sequesters in both marine and lacustrine environments. Terrestrial Si cycling and especially fluxes across the vegetation-soil interface are highly
This study explores entrepreneurship discourses in literature about entrepreneurial learning in Swedish elementary school and what subjects these aim to shape. The aim is to examine what motivates changes to entrepreneurship, how it is defined, and what political notions of the social and gender it establishes by using feminist theoretical premises, analytic categories of hegemony and subject form
This Master Thesis project is a pilot study in developing a collision avoidance function for an autonomous underwater vehicle, also called AUV. A collision avoidance function is necessary to ensure safe operation of an AUV. The AUV gets information about the surroundings through an active sonar. The image from the sonar has to be processed to extract information about the environment, e.g., detect
The purpose of this thesis is to investigate how the autonomy in an acquired subsidiary affects the integration process within an M&A process. The study uses a qualitative and deductive method by conducting a case study in a major Swedish technological company. We have made five different hypotheses based on three prominent articles within the M&A research area that deal with the subject o
Illegal timber harvest and trade is one of the main challenges in the context of global deforestation and sustainability. Different governance and self-governance initiatives throughout the history with the aim to regulate global forest commons have received plenty of criticism. This research investigates the potential of genetic timber tracking technologies as a tool to enhance existing systems a
The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicl
Background: Non-motor symptoms (NMS) are integral to Parkinson's Disease (PD) and management remains a challenge. Safinamide is a novel molecule in relation to addressing NMS due to its multifocal mechanism of action with both dopaminergic and non-dopaminergic properties. Objective: To investigate the efficacy of safinamide on NMS and its burden in PD patients with motor fluctuations after 6 month
Although rooted in the history of humankind, child labour has become a matter of increasing global attention. Significant steps have been taken in the international arena to combat the problem. However, its prevalence gives reasons for concerns. According to latest estimates of the International Labour Organization, 215 million children in the world are still caught up in child labour and 115 mill
Världen blir alltmer globaliserad och statsgränsen har inte samma betydelse. Det internationella samfundet växer snabbt där stater blandar sig i varandras angelägenheter alltmer. Humanitära interventioner sker i större utsträckning och intresset att ingripa har ökat mycket senaste åren. Uppsatsen ämnar göra en jämförande fallstudie med interventionerna Kosovo och Libyen som studieobjekt. Med utgån
The aim of this study is to examine the role of PR firm Qorvis as an intermediary actor in Saudi Arabian public diplomacy. Qorvis, an American registered company, has been on the kingdom's pay list since the events of 9/11, providing it with services such as strategic communication and international outreach. Since the launching of Saudi Arabia’s Vision 2030 in 2016, Qorvis has played a decisi
This paper discusses the potential economic consequences of the countervailing duty imposed on solar panels imported from China by the EU. The paper is motivated by recent studies that indicate potential future costs from a world energy market that is characterized by technics that give rise to high relative levels of carbon dioxide. The intention is to discuss the potential effect that countervai
Sustainable development has been recognized as a global concern by the majority of the countries around the world. The importance of education for sustainable development for reaching sustainability has been recently emphasized by the international community. As a result of this recognition, the decade of education for sustainable development has been initiated by UN. The purpose of this thesis i
In times of globalization, cultural contact is a phenomenon that occurs on a daily basis. Immigration is a big contributor to the cultural contact. The phenomenon of immigration brings about many essential questions that can be hard to adjust to. The acculturation process itself is dependent of factors such as the contemporary societal climate as well as the active role of the immigrant. Questions
Sustainable development as a policy concept has during the last twenty years developed into a huge field where the environmental, economic and social areas of society are being intertwined. And the aim of these policies is to reach the goal of a global sustainable future for all. Even though, the social aspects of sustainable development has been shown to often be neglected in the analysis, and no
Abnormally phosphorylated tau proteins are known to be a major indicator of Alzheimer's Disease (AD) with strong association with memory loss and cognitive decline. Automated generation of pixel-wise accurate neurofibrillary tangles (NFTs) and neuropil threads (NTs) segmentation is a challenging task, due to lack of ground truth segmentation data of these abnormal tau pathology. This problem is mo
Purpose: Serious mental illnesses (SMIs) exert a considerable financial burden on health-care systems. In this study, the resource utilization in mental illness (RUMI) tool was developed and employed to evaluate resource utilization in patients with SMI. Materials and methods: Data from 107 patients with SMI treated in four psychiatric outpatient clinics in Sweden were collected. The relationships
