This paper examines the “back-testability” of Expected Shortfall and if different backtesting methods produce similar results, with the aim of illuminating whether various markets have any effect on the methods’ ability to perform. In order to answer this question, the three backtesting methods – Test 1 and Test 2 by Acerbi & Szekely, and the Approximative Quantile Test by Emmer et al. – are i
Understanding the bacterial growth process – apical growth Have you ever thought about chopping yourself in half? Separating a limb maybe? If you haven’t – I don’t blame you – it would be pretty weird. But this isn’t about you or me – it’s about bacteria – and they are pretty weird. The different ways bacteria grow and proliferate are pretty diverse – one interesting, although a bit saner – is a
Prior articles and reports have named Credit Default Swap (CDS) spreads as a plausible indicator of default risk. In this report, the authors present a significant correlation between CDS spreads and two other more acknowledged methods of measuring default risk probabilities; the modified Merton model and credit ratings from the rating institute Moody’s. The tests are implemented by Spearman’s ran
The main sustainability goal of many small islands in the North Sea is to become self supplied in renewable energy in 20-30 years. The majority of the islands are trying to repeat Samsø‘s success – to make a transition towards energy sustainable system by new energy production from local renewable sources such as wind, solar and biomass. However, for other islands like Spiekeroog island, a tourist
The objective of this thesis was the impact evaluation of several parameters affecting daylight conditions in a typical cellular office in Lund, Sweden. The research approach that was followed consisted of three distinct steps; the literature review in order to specify the dependent and independent variables of the study, the simulation part to produce daylight performance data and the graphical a
Urbanization is a process where rural population move to urban places for better job opportunities and facilities. This is a natural process and more or less unavoidable. But when this process takes place rapidly and at large -scale, the urban cities will undergo various changes that will impact the environment. Rapid and large-scale urbanization is mainly observed in developing countries of Asia
The reduction of the (A root 5x root 5)R27 degrees surface oxide on Pd(100) and Pd75Ag25(100) surfaces by CO has been investigated by high-resolution X-ray photoelectron spectroscopy in combination with kinetic analysis using the Avrami-Erofeev theory. For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary
In this study we investigate the effect of programmed cross-flows on the error in the hydrodynamic radii (r(h)) determination with asymmetrical flow field-flow fractionation (AsFlFFF). Three different standard polystyrene particles (nominal radii of 30 and 40 and 50nm) are fractionated with exponentially and linearly decaying cross-flows with different decay rates. Hydrodynamic radii are calculate
The nearest neighbour level spacing distribution and the Δ3 statistic of level fluctuations associated with very high spin states (I ≳ 30) in rare-earth deformed nuclei are analysed by means of a cranked shell model. The many particle-many hole configurations created in the rotating Nilsson potential are mixed by the surface-delta two-body residual interaction. The levels in the near-yrast region
Introduction Common complications after surgical procedures include surgical site infection, wound rupture and incisional hernia. Wound healing can be influenced by the technique for abdominal access and closure. A Suture-Length to Wound-Length (SL/WLr) ratio ≥ 4 is advised to achieve a high-quality wound closure. This thesis describes the background and clinical realities of abdominal wall relate
For over 30 years GIS has been a major theme in archaeology, leading scholars to debate the way geo-spatial platforms can contribute to a better understanding of the ancient landscape and a more thorough interpretation of the archaeological record. Recently, the introduction of more advanced software and hardware solutions have made it possible to use GIS for visualizing and analysing even geometr
Background: Hyperuricemia (HU) is in the causal pathway for developing clinical gout. There are few population-based assessments of the absolute and relative risk of clinically diagnosed incident gout in subjects with HU. We aimed to explore the long-term risk of developing incident gout among asymptomatic adults with different levels of serum urate (SU). Methods: Malmö Preventive Project was a po
Today there are climate policy targets within the EU and Sweden about limiting global warming and drastically reducing greenhouse gas emissions. In order to stay within the goal of a global warming of less than 2 ºC, the industrialised countries should decrease their emissions by 80-95 % in 2050, and bring them down to zero in the longer run. Scenario studies indicate that this is possible to achi
The semiarid Punata alluvial fan is located in the central part of Bolivia. The main activity of this region is the extensive agriculture, and groundwater is the main water supply. Local villagers who use groundwater reported that in some places groundwater has a salty taste. In order to investigate the origin of this problem, several TEM soundings were performed in the study area, and they were c
In order to investigate whether oxidative damage is associated with differences in antioxidant intake, we measured the levels of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) in lymphocytes and α-tocopherol and several carotenoids in plasma of women with different dietary habits. We found that women from Granada (Spain), a region with a typically Mediterranean diet, had significantly higher leve
This paper approach participation in visual promotional strategies as a novel form of public performance. The paper examines the social rules and conventions of photography practices on visual social media platforms in a qualitative study of how 30 participants in so-called Instagram takeovers make sense of and perform photography as an embodied visual practice situated in time and space.A dramatu
The total pancreatic lipolytic capacity was determined in duodenal contents in healthy humans 10-120 min after a liquid test meal, by estimating the amount of pancreatic lipase, colipase, carboxyl ester lipase, and phospholipase A2 by means of radioimmunoassays and enzymatic assays. The molar concentrations of the different proteins were of the same order of magnitude. The relative specific activi
5-Hydroxymethylfurfural (HMF), a product of catalytic dehydration of C6 sugars, is a versatile and key renewable platform chemical. The possibility to use a high substrate concentration with high yield in a single-solvent system is one of the solutions to reduce solvent usage, energy consumption, reaction volume, and operating cost. A heterogeneous catalyst and single-solvent system were employed
Mentoring – Step Up 2013 What is Mentoring? Roots back to the Greek mythology When Odysseus le, for the Trojan War, he entrusted his friend Mentor with the task of raising his son Telemachos in his absence and to promote the boy’s development. In the English-‐language literature, mentoring is defined as: “A process whereby an
