This thesis muses the question; how do we understand firm growth in immigrant owned firms? Two literature streams are proposed to be relevant. Firstly, theimmigrant entrepreneurship field, which is developing and becoming increasinglysophisticated. Though despite appeals from within the field, that we need a widerspan of concepts to explain the changing heterogeneity and fabric of immigrantentrepr
An improvement in our process-based understanding of carbon (C) exchange in the Arctic and its climate sensitivity is critically needed for understanding the response of tundra ecosystems to a changing climate. In this context, we analysed the net ecosystem exchange (NEE) of CO2 in West Greenland tundra (64°N) across eight snow-free periods in 8 consecutive years, and characterized the key process
Background & Aims Predniso(lo)ne, alone or in combination with azathioprine, is the standard-of-care (SOC) therapy for autoimmune hepatitis (AIH). However, the SOC therapy is poorly tolerated or does not control disease activity in up to 20% of patients. We assessed the efficacy of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy for patients with AIH. Methods We performed a r
In this paper, we consider positioning with observed-time-difference-of-arrival (OTDOA) for a device deployed in long-term-evolution (LTE) based narrow-band Internet-of-things (NB-IoT) systems. We propose an iterative expectation- maximization based successive interference cancellation (EM-SIC) algorithm to jointly consider estimations of residual frequency- offset (FO), fading-channel taps and ti
Background: Response to modern treatment strategies, which combine cytotoxic compounds with immune stimulatory agents and targeted treatment is highly variable among MCL patients. Thus, providing prognostic and predictive markers for risk adapted therapy is warranted and molecular information that can help in patient stratification is a necessity. In relapsed MCL, biopsies are rarely available and
The global cobalt cycle in society was modelled using an integrated systems dynamics model, WORLD6, integrating several earlier system dynamics models developed by the authors. The COBALT sub-model was used to assess the long-term sufficiency of the available extractable cobalt and address the effect of different degrees of recycling on cobalt supply. The extraction of cobalt is mostly dependent o
Continuously monitoring its position in space relative to a goal is one of the most essential tasks for an animal that moves through its environment. Species as diverse as rats, bees, and crabs achieve this by integrating all changes of direction with the distance covered during their foraging trips, a process called path integration. They generate an estimate of their current position relative to
The fate of phosphate in the environment is governed by reactions at particle surfaces. These adsorption and desorption reactions display biphasic kinetics involving an initial rapid reaction followed by a substantially slower one extending over long time periods. In this study we have investigated the molecular mechanisms of desorption kinetics of phosphate from ferrihydrite and goethite nanopart
Fractures of the distal end of the radius are common and occur in many different forms. The long-term results after conservative treatment of fracture of the distal end of the radius in younger adults with special reference to degenerative changes and function are investigated in 76 patients (Paper I). After 30 years, 81% of the patients made no difference between the fractured and the non- fractu
This thesis addresses three different topics in wind power plant operation. Most of the research is focused on controlling a wind farm that is required to meet a power set-point. In this mode of operation, the wind turbines are able to vary their power production as long as the total power demand is met. The research investigates how this freedom can be used in order to reduce the fatigue loads e
The two major aims of this study are (1) To test the performance of the Landscape Reconstruction Algorithm (LRA) to quantify past landscape changes using historical maps and related written sources, and (2) to use the LRA and map reconstructions for a better understanding of the origin of landscape diversity and the recent loss of species diversity. Southern Sweden, hemiboreal vegetation zone. The
In optically controlled quantum computers it may be favorable to address different qubits using light with different frequencies, since the optical diffraction does not then limit the distance between qubits. Using qubits that are close to each other enables qubit-qubit interactions and gate operations that are strong and fast in comparison to qubit-environment interactions and decoherence rates.
Popular Abstract in Swedish Trots ett sunt leverne med regelbunden motion och nyttig mat kan vi inte alltid förhindra risken att drabbas av vissa typer av cancer som till exempel hjärntumörer. Den vanligaste formen av elakartade hjärntumörer heter glioblastoma multiforme och är också den mest aggressiva. Symptomen varierar beroende på tumörens storlek och var i hjärnan den växer, och patienter kanGlioblastoma multiforme (GBM) is the most common and aggressive primary malignant brain tumor in adults. Despite standard treatment including surgery, radiotherapy and temozolomide (TMZ)-based chemotherapy, the prognosis for GBM patients is dismal, and there is a need for novel treatments. One possible therapeutic treatment modality presented here is immunotherapy, either alone or combined with in
This article considers the challenges faced by digital evidence specialists when collaborating with other specialists and agencies in other jurisdictions when investigating cyber crime. The opportunities, operational environment and modus operandi of a cyber criminal are considered, with a view to developing the skills and procedural support that investigators might usefully consider in order to r
How can tools help structure tasks to make them cognitively easier to perform? How do artefacts, and our strategies for using them, develop over time in cognitively beneficial ways? These are two of the main questions that are explored in the five papers collected in this thesis. The first paper details an ethnographic study conducted on people cooking in their homes. The study is a first pass ov
This dissertation aims to investigate and analyze people's preparation for retirement. The study has been made through semi-structured interviews with 78 people born between the years 1931-1981 regarding their preparations for retirement. The analysis is based on the model Reflexive Planning for Later Life, coping, bounded rationality, behavioural finance and the concept of governmentality, and
In the wake of the atrocities of the twentieth century, the standard account of the Enlightenment, as a warranty of universal ideals of rationality and morality, has been challenged from a number of different angles. In line with these critical discourses, the present article investigates how, to a significant extent, two of the greatest philosophers of reason, Kant and Hegel, underpin their unive
Background: Worldwide, insulin-dependent type 1 diabetes is one of the most frequently diagnosed long-term endocrine disorders found in children and the incidences of this diseased is still increasing. In Sweden the routines are, according to national guidelines, when the child is diagnosed with type 1 diabetes, the child and its family remains at the hospital for about two weeks. There is limited
We analysed satellite tracking data to reveal the daily travel schedules of Hobbies Falco subbuteo migrating between northern Europe and southern Africa. By comparing movements during short-time intervals of 1-8 h at different times of the day between the three different regions Europe, Sahara Desert and tropical Africa, we found significant higher hourly speeds in the Sahara compared to the other
Background: Selective dorsal rhizotomy (SDR) is an operation method that decreases the degree of spasticity with long-lasting beneficial effects for children with spastic diplegia. Children undergoing SDR are postoperatively in severe pain, a pain related to both the extensive surgical exposure with multilevel laminectomy and the nerve root manipulation. Various pain management strategies for chil
