Purpose: The purpose of this research is to find out if there is connection between current financial position of banks and level of risk disclosure in their annual reports. Methodology: The thesis is based on an abductive approach. Research strategy of this research is a qualitative method. Learning of annual reports is used as a method of collecting empirical data. Comparison was based on a sele

We investigated allozyme variation in 34 populations of the perennial herb Silene nutans from Sweden and northern Finland, areas that were ice-covered during the last (Weichselian) glaciation. The present geographical structure of genetic variation in S. nutans in Sweden and northern Finland appears to have been mainly shaped by ancient historical processes. Patterns of variation in allele frequen

Secondary objectives:Secondary objectives:P Primary objective: To assess whether head midline position compared with any other head position is more effective in prevention or extension of germinal matrix-intraventricular hemorrhage in infants born at ≤ 32 weeks' gestational age. Secondary objectives: To perform subgroup analyses regarding gestational age, birth weight, intubated versus not intuba

Background: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure an

Until relatively recently, a diagnosis of probable Alzheimer's disease (AD) and other neurodegenerative disorders was principally based on clinical presentation, with post-mortem examination remaining a gold standard for disease confirmation. This is in sharp contrast to other areas of medicine, where fluid biomarkers, such as troponin levels in myocardial infarction, form an integral part of the

Popular Abstract in Swedish Denna avhandling behandlar tillväxt av och elektriska mätningar på halvledande nanotrådar av indiumarsenid (InAs) och kombinationer av InAs och indiumfosfid (InP). En nanotråd är som namnet antyder en tunn solid tråd, som påminner om ett hårstrå fast med en diameter på typiskt 50 nm (en nanometer är en miljarddels meter, 10^-9 m) och längden kan vara allt från 100 nm upIn this thesis, semiconductor nanowires are studied from the point of view of growth and electrical properties. The growth of nanowires is done by chemical beam epitaxy (CBE), an ultra-high vacuum technique allowing a precise control of precursor deposition and low growth rates. In conventional epitaxy, growth is usually two or three- dimensional, depending on growth conditions and material combin

Thesis Purpose: The purpose of this thesis is to reveal and enable a deeper understanding of the intersections of the three fields of Employer Branding, Social Media, and Generation Y. Moreover, the connecting points of these fields and in particular the concrete activities that are incorporated by Employers of Choice in order to attract Generation Y’s high potentials via a Social Media Employer

This thesis deals with the dynamical processes in atoms and small molecules initiated by the absorption of ultrashort, coherent light pulses. The studied phenomena takeplace on the femtosecond (1 fs = 10−15 s) and attosecond (1 as = 10−18 s) timescales and critically depend on the properties of the light fields that drive them. Wework with infrared (IR) femtosecond laser pulses, which we manipulat

Organic-inorganic heterostructures play a pivotal role in modern electronic and optoelectronic applications including photodetectors and field effect transistors, as well as in solar energy conversion such as photoelectrodes of dye-sensitized solar cells, photoelectrochemical cells, and in organic photovoltaics. To a large extent, performance of such devices is controlled by charge transfer dynami

ABSTRACT AND INTRODUCTION Theories of text and discourse have long assumed the existence of semantic objects called discourse referents, "things being talked about and referred to by pronouns and definite noun phrases"(cf. e.g. Karttunen (1976), Sigurd (1982), Sidner (1983)). Such referents are also often alluded to in sentence grammars, above all in theories of pronominalization and control -ofte

The paper presents Referent Grammar (RG), a version of generalized phrase structure grammar. RG uses descriptive labels for defective categories (categories tacking a constituent) instead of slash expressions and needs no null (empty, zero) categories. RG uses both functional and categorial representations and the grammar rules, written in the Prolog DCG formalism, relate these two levels. The fun

Retinal dystrophies (RD) constitute a group of blinding diseases that are characterized by clinical variability and pronounced genetic heterogeneity. The different nonsyndromic and syndromic forms of RD can be attributed to mutations in more than 200 genes. Consequently, next generation sequencing (NGS) technologies are among the most promising approaches to identify mutations in RD. We screened a

This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. This spectrum is subsequently modeled to pass thr

Traditional high level synthesis is able to yield high computational resource utilisation and short critical paths. The shortcomings of the generated designs usually lies in the memory architecture. To achieve good performance on a FPGA, the data must reside in the fast on-chip memories, but these are commonly too small for the data being processed. Traditional high level synthesis cannot cope wit

Generation of clusters of free eosinophil granules (Cfegs), through lysis of eosinophils, has recently been proposed as a major paradigm for ultimate activation of airway mucosal eosinophils. In the present study involving patients with seasonal allergic rhinitis, we have investigated whether generation of Cfegs in the nasal mucosa is a feature of allergic rhinitis. Nasal mucosal biopsies were obt
