Risk disclosure is generally regarded as crucial in order for investors to make informed decisions in the resource allocation process. Our study is the first to empirically investigate the value-relevance of corporate risk disclosure. We focus on the disclosure of foreign exchange (FX) risk, which is an activity notorious for its lack of transparency. Our empirical analysis involves a FX risk disc

We have calculated the reorganization energy for the intramolecular electron transfer between the reduced type 1 copper site and the peroxy intermediate of the trinuclear cluster in the multicopper oxidase CueO. The calculations are performed at the combined quantum mechanics and molecular mechanics (QM/MM) level, based on molecular dynamics simulations with tailored potentials for the two copper

Popular Abstract in Swedish I vår egen tid finns ett stort intresse för släktforskning och historia hos många. Men man tänker sällan på att även människor i gångna tider kunnat blicka tillbaka på sitt förflutna och fundera på sin egen plats i släktleden. Vad var de ville minnas och hur mindes de i en tid utan skriv- och läskunnighet? Det är frågor som ställs i avhandlingen och där svaren söks i deThis thesis examine how farm-dwellers in the Mälaren region during the late Iron Age and early Middle Ages created, transferred, and preserved memory by deliberately placing new houses and graves on the houses and graves of previous generations. Focus is on memory as a social phenomenon and culture-specific resource created by these deliberate practices. The culture-specific element is oral cultur

Land development usually induces large changes in flood peak and infiltration properties, thus affecting the entire hydrological environment of the area. In order to evaluate such negative effects caused by land-use change, it is necessary to estimate the changes in surface runoff and groundwater recharge rate. The effects of land-use changes on the parameter values of a groundwater recharge model

Crystallization of amorphous Y67Fe33 into the YFe2 C15 Laves phase via a novel 'YFe' intermediate phase has been observed through to completion using time-resolved small angle neutron scattering (SANS). The nucleation and growth kinetics of the phase transformations have been studied at annealing temperatures below the crystallization temperatures for both the 'YFe' phase and the YFe2 phase. The S

In the year 2000, the alcohol habits of 1460 Swedish university students living in residence halls were assessed. The students had a mean age of 23.8 years, and 64% were male. The results from this baseline assessment show that the mean AUDIT score (± sd) was 10.3 ± 5.2 for males and 8.1 ± 4.7 for females. AUDIT stands for Alcohol Use Disorders Identification Test and is used world-wide to assess

The negative impacts of surface ozone (O(3)) on vegetation are determined by external exposure, leaf gas exchange and plant antioxidant defence capacity, all dependent on climate and CO(2) concentrations. In this study the influence of climate change on simulated stomatal O(3) uptake of a generic crop and a generic deciduous tree at ten European sites was investigated, using the LRTAP Mapping Manu

Tunas make sharp descents and ascents around dawn and dusk called spike dives. We examine spike dives of 21 southern bluefin tuna (Thunnus maccoyii) implanted with archival tags in the Great Australian Bight. Using a new way to categorize this behavior, we show that spike dives are similar among all the fish in the study. The dive profiles are mirror images at dawn and dusk and are precisely timed

The tracking of small avian migrants has only recently become possible by the use of small light-level geolocators, allowing the reconstruction of whole migration routes, as well as timing and speed of migration and identification of wintering areas. Such information is crucial for evaluating theories about migration strategies and pinpointing critical areas for migrants of potential conservation

Objective: A voluminous umbilical cord has been described in diabetic pregnancies. The aim of this study was to see if measurements of cord diameters might be of value in the evaluation of diabetic pregnancies and especially those suspected of a large for gestational age (LGA) fetus. Methods: In an observational, prospective study umbilical cord areas and vessel diameters were measured between ges

Popular Abstract in English Sweden’s elderly population is growing, propelled by a continuous decline in old-age mortality, while coupled with a persistent replacement level fertility. This changing age structure increases the per worker cost of providing a given age-vector of per capita benefits, encompassing costs for pensions, health care, and all other type of old-age welfare services, which pSweden’s elderly population is growing, propelled by a continuous decline in old-age mortality, while coupled with a persistent replacement level fertility. This changing age structure increases the per worker cost of providing a given age-vector of per capita benefits, encompassing costs for pensions, health care, and all other type of old-age welfare services, which presents a looming challenge

AimsTo determine whether antivirus and/or islet cell antibodies can be detected in healthy pregnant mothers without diabetes and/or their offspring at birth in two winter viral seasons. MethodsMaternal and cord blood sera from 107 healthy pregnant women were tested for islet cell autoantibodies using radioligand binding assays and for anti-rotavirus and anti-CoxB3 antibody using an enzyme-linked i

Aims. We describe how the C IV lambda 1548.18 line pumps the 1548.20 and 1548.41 angstrom channels of Fe II in symbiotic stars through the process known as photo-ionization by accidental resonance (PAR). We describe where and why Fe II fluorescence arises in symbiotic stars and whether the Fe II lambda 1548.41 channel can only be activated when there is a white-dwarf wind present in the system. Fu

We present a set of spectrally and temporally resolved clinical fluorescence data-with two separate excitation wavelengths-that was recorded in vivo. We demonstrate that data in the spectral and temporal domains are in certain ways coupled and provide a method for integrated and effective parameterization of spectrally and temporally resolved fluorescence (i.e., time-resolved emission spectra). Th

A survey on household waste sorting and disposal habits was conducted in Sweden to investigate behavioral patterns of recycling in a context in which wide measures are taken to promote and encourage pro-environmental behavior by making it easy and convenient. 207 residents of three cities in southern Sweden, Lund, Malmö and Helsingborg, responded to an online questionnaire survey. Relations betwee

Most climate change scenarios predict that the variability of weather conditions will increase in coming decades. Hence, the frequency and intensity of freeze-thaw cycles in high-latitude regions are likely to increase, with concomitant effect on soil carbon biogeochemistry and associated microbial processes. To address this issue we sampled riparian soil from a Swedish boreal forest and applied t

Tasquinimod, an orally active quinoline-3-carboxamide, binds with high affinity to HDAC4 and S100A9 in cancer and infiltrating host cells within compromised tumor microenvironment inhibiting adaptive survival pathways needed for an angiogenic response. Clinical trials document that as low as 0.5-1mg tasquinimod/day is therapeutic against castrate resistant metastatic prostate cancer. Tasquinimod i
