Climate change influences population demography by altering patterns of gene flow and reproductive isolation. Direct mutation rates offer the possibility for accurate dating on the within-species level but are currently only available for a handful of vertebrate species. Here, we use the first directly estimated mutation rate in birds to study the evolutionary history of pied flycatchers (Ficedula
Public preferences for sustainable land use policy instruments and the motivations behind such preferences are important to make appropriate policies. Based on survey data (n = 309) from northeastern Somalia, we examined preferences for a set of land use policy instruments relative to no policy (i.e. the current status quo) and how cultural worldviews predict such preferences. We used a multinomia
This study contributes to fill the gap in the existing community health worker literature by offering a more nuanced perspective on performance motivation of healthcare workers from rural South Africa. Specifically, it focuses on the various work incentives and perceived organization support that shape work performance of healthcare workers and, therefore, organizational effectiveness. By followin
This thesis is essentially a project in theory- and method-building. It engages the strengths of Vaughan-Williams’ alternative border imaginary under the name of the generalised biopolitical border (GBB) in accounting for the complexity of border phenomena in contemporary global politics. However, it identifies two major shortcomings related to Vaughan-Williams’ application of the GBB to various e
Purpose: Most studies on paediatric pharyngotonsillitis focus on group A streptococci. This study, however, analyses a broad spectrum of bacteria and viruses related to paediatric pharyngotonsillitis and evaluates their associated clinical symptoms and courses. Methods: This observational prospective study in primary healthcare includes 77 children aged < 15 with a sore throat and 34 asymptomatic
Overuse of resources is accelerating today’s negative trends in climate change, ecosystem destruction, and biodiversity loss. The ultimate result is contemporary human societies are reaching or exceeding the limits of planetary boundaries. It is therefore imperative to articulate a new theoretical understanding of resources and the ethical, political and environmental conditions of their use. In t
Growth and hydrogen production by two extreme thermophiles during sugar fermentation was investigated. In cultures of Caldicellulosiruptor saccharolyticus grown on sucrose and Thermotoga elfii grown on glucose stoichiometries of 3.3 mol of hydrogen and 2 mol of acetate per mol C6-sugar unit were obtained. The hydrogen level was about 83% of the theoretical maximum. C. saccharolyticus and T. elfi
Supercritical heat transfer deterioration can be found in active regenerative cooling processes. Thermal pyrolysis occurs once the temperature of the hydrocarbon fuel exceeds a certain value. To investigate the influence of thermal pyrolysis on the heat transfer behavior and flow-upward characteristics in a rectangular channel, the wall temperature distribution, thermal acceleration, mass fraction
The etiology of hereditary ataxia syndromes is heterogeneous, and the mechanisms underlying these disorders are often unknown. Here, we utilized exome sequencing in two siblings with progressive ataxia and muscular weakness and identified a novel homozygous splice mutation (c.3020-1G > A) in neurofascin (NFASC). In RNA extracted from fibroblasts, we showed that the mutation resulted in inframe ski
Äldre anställdas ställning på arbetsmarknaden är onekligen osäker. I detta arbete försöker jag att räta ut och förstå hur äldre arbetstagare är skyddade på arbetsmarknaden genom att undersöka hur gällande rätt är designat. Detta görs genom en komparativ studie mellan Sverige och Kina, där en rad olika undersökningsområden kopplat till anställningsskydd för äldre bearbetas. Arbetet berör och förklaThe status of the elderly on the labour market is undeniably precarious. In this thesis, I am trying to straighten out how the elderly are protected on the labour market and how the legislation to protect them is designed. This is done through a comparative study between Sweden and China, where a number of research areas associated with employment protection for elderly are processed. I am, in thi
Due to globalization, increasing amounts of water are traded across borders as virtual water embodied in traded products. The thesis traces global water trade patterns at different levels of income between 1990 and 2015 in order to test whether developed countries outsource their water-intensive production to less developed countries increasing global water use in the process. The research problem
Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. However, quantitative relationships between barrier and inland production well have not been re
In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. The DPAs are designed using AWR design environment with virtual source (VS) models of In(Ga)As nanowire transistors and 50 nm gate length. Th
By testing theories from the likes of Seymour Martin Lipset and Francis Fukuyama, this thesis aims to illuminate the correlations between the size of a nation’s middle class and the stability and rigor of its democracy. Using quantitative data on democracy and middle class size in the time surrounding the financial crisis of 2008-2010, this thesis illustrates the parallel declines in both democrac
Multiple techniques for quantification of hippocampal subfields from in vivo MRI have been proposed. Linking in vivo MRI to the underlying histology can help validate and improve these techniques. High-resolution ex vivo MRI can provide an intermediate modality to map information between these very different imaging modalities. This article evaluates the ability to match information between in viv
The inclusive Higgs boson production cross-section is measured in the di-photon and the ZZ∗→ 4 ℓ decay channels using 31.4 and 29.0 fb - 1 of pp collision data respectively, collected with the ATLAS detector at a centre-of-mass energy of s=13.6 TeV . To reduce the model dependence, the measurement in each channel is restricted to a particle-level phase space that closely matches the channel’s dete
The major aim of the study was to investigate whether differences concerning acceptance of dental treatment and amnesia after rectal sedation with midazolam can be explained by temperament traits in the child. Fifty children (1.5- 4.0 years), consecutively referred for dental extractions because of dental trauma or caries, were sedated with midazolam 0.3 mg kg(1) rectally. Level of sedation (state
