The aim of the present study was to examine mean HbA1c and blood pressure levels during a 5 year period in 442 type 1 adult diabetic patients in relation to the incidence and progression of retinopathy, nephropathy and to cardiovascular morbidity and mortality. The study showed, that in patients under routine care at a diabetic unit with four visits to the out-patient clinic per year, the intraind
We study theoretically the linear conductance of a quantum dot connected to ferromagnetic leads. The dot level is split due to a noncollinear magnetic field or intrinsic magnetization. The system is studied in the noninteracting approximation, where an exact solution is given, and, furthermore, with Coulomb correlations in the weak tunneling limit. For the noninteracting case, we find an antireson
The editors and contributors reflect on ethics and reflexivity in critical management research, and explore the identity of the critical researcher both as an individual and working within collaborative projects. Using contemporary accounts from those engaged in real world fieldwork they outline what critical management is, and explore its relationship to management research. The book discusses t
This paper introduces a suite of tests for linear and general non- linear serial dependence. The problem is complex as the number of variations of realistic non-linear alternatives is very large. The alternative model is dened in terms of penalized truncated polynomial splines, making the approximation capable of accurately approximating a large class of linear and non-linear processes. The asympt
Marker-based studies of inbreeding may lead to an enhanced understanding of inbreeding depression in natural populations, which is a major concern in conservation genetics. Correlations between marker heterozygosity and variation in fitness-associated traits—‘heterozygosityfitness correlations’ (HFCs)—are of particular importance and have been widely applied in natural populations. In partially in
There is need for structured evaluation of disability before and after surgery. The patients' subjective aspects of their symptoms should be one part of this evaluation, preferably captured by patient-reported outcome measures (PROMs). There are several PROMs, either generic or region-specific questionnaires, but no » gold standard « for foot or ankle evaluation. We translated the Self-reported Fo
I will start by noting that Harry Frankfurt’s concept of wholeheartedness is in conflict with the intuition that free will should be efficacious in general, rather than pertain only to a small subset of decisions. To replace wholeheartedness I introduce a heuristic account for deliberation and decisions. I will show that introspective activity can lead to the individual having two types ‘introspec
The fairly new VIX ETPs have been promoted for providing effective and easily accessible diversification, while at the same time having large negative returns. We examine the economic value of using VIX ETPs for diversification of stock–bond portfolios. Our analysis begins in 2009, when the first VIX ETPs are introduced, and therefore only considers the period after the recent financial crisis. Fo
Eldh discusses the challenges in teaching quantitative methods, in this case statistics, in interdisciplinary courses with mixed methods where both qualitative and quantitative methods are taught. Despite this, most students tend to choose to use qualitative methods in their thesis research and the author researches why this is the case. Literature suggests that students often find statistics cour
Henzinger et al. posed the so called Online Boolean Matrix-vector Multiplication (OMv) conjecture and showed that it implies tight hardness results for several basic partially dynamic or dynamic problems [STOC’15].We show that the OMv conjecture is implied by a simple off-line conjecture. If a not uniform (i.e., it might be different for different matrices) polynomial-time preprocessing of the mat
We present a parameter-free scheme to combine fixed-order multi-jet results with parton-shower evolution. The scheme produces jet cross sections with leading-order accuracy in the complete phase space of multiple emissions, resumming large logarithms when appropriate, while not arbitrarily enforcing ordering on momentum configurations beyond the reach of the parton-shower evolution equation. This
The paper proposes a new multiple window method for estimating a peaked spectrum. The multiple windows are adapted to the signal, giving a less biased estimate for estimation of peaks than does the Thomson multiple window method. Still the result from estimation of a flat spectrum shows comparable results in variance reduction. The method is based on solution of an eigenvalue problem where the eig
This article aims to examine whether it is possible to rework transversearrowheads while still hafted, in order to reuse them. Three series, eachcontaining three arrows, were shot into a target consisting of meat andbone. When possible, the arrowheads were retouched and fired again.The results of the experiments demonstrate that it is possible to reworktransverse arrowheads while they are hafted a
In this study, we revisit the factor analytical (FA) approach for (near unit root) dynamic panel data models, whose asymptotic distribution has been shown to be normal and well centered at zero without the need for valid instruments or correction for bias. It is therefore very appealing. The question is: Does the appeal of FA, which so far has only been documented for fixed effects panels, extends
Owing to the prevalence of fractal patterns in natural scenery and their growing impact on cultures around the world, fractals constitute a common feature of our daily visual experiences, raising an important question: what responses do fractals induce in the observer? We monitored subjects’ EEG while they were viewing fractals with different fractal dimensions, and the results show that significa
Spurred on by pressure to find sustainable energy production alternatives to fossil fuels, many industries have been acquiring land in order to plant crops for biofuel production. In Tanzania, biofuel development is in an early stage, and over the last decade, several foreign actors have tried to start up biofuel projects in the country (without success). Land acquisitions are seen by many as a fo
This paper investigates the effects of Brexit on export performance of the United Kingdom towards the rest of the EU15. It does so by first establishing a “hard Brexit” as the probable outcome. Using the gravity model it then establishes the effect of variables such as distance and GDP per capita on exports. These effects are found by running the regression on a sample of four non-EU countries dur
