The resolution of the phylogenetic relationships within the order Teloschistales (Ascomycota, lichen-forming-fungi), with nearly 2000 known species and outstanding phenotypic diversity, has been hindered by the limitation in the resolving power that single-locus or two-locus phylogenetic studies have provided to date. In this context, an extensive taxon sampling within the Teloschistales with more
Prophylactic treatment in severe hemophilia is very effective but is limited by cost issues. The implementation of 2 different prophylactic regimens in The Netherlands and Sweden since the 1970s may be considered a natural experiment. We compared the costs and outcomes of Dutch intermediate-and Swedish high-dose prophylactic regimens for patients with severe hemophilia (factor VIII/IX < 1 IU/dL) b
Biogenic silica (BSi) is used as a proxy by soil scientists to identify biological effects on the Si cycle and by palaeoecologists to study environmental changes. Alkaline extractions are typically used to measure BSi in both terrestrial and aquatic environments. The dissolution properties of volcanic glass in tephra deposits and their nanocrystalline weathering products are hypothesized to overla
Objectives: To evaluate screening for retinopathy of prematurity (ROP) in Sweden and to investigate possible modifications of the present screening guidelines. Methods: Infants in Sweden with a gestational age (GA) of 31 weeks + 6 days or less are screened for ROP. Data from the Swedish national register for ROP (SWEDROP) during 2008 and 2009 were extracted and compared with a national perinatal q
The purpose of this paper is to present the optimal number of windows and window lengths using multiple window spectrogram for estimation of non-stationary processes with shorter or longer duration. Such processes could start in the EEG as a result of a stimuli, e.g. steady-state visual evoked potentials (SSVEP). In many applications the Welch method is used with standard set-ups for window length
The Rostanga-1 core from west-central Scania provides the most complete succession of the Sandbian (Upper Ordovician) through lower Telychian (Silurian, Llandovery) strata of southern Scandinavia. The Hirnantian is identified in the Kallholn Formation by the presence of a Metabolograptus persculptus Biozone fauna. The Akidograptus ascensus, Parakidograptus acuminatus, Cystograptus vesiculosus and
Thermal-optical analysis is a conventional method for determining the carbonaceous aerosol fraction and for classifying it into organic carbon, OC, and elemental carbon, EC. Unfortunately, the different thermal evolution protocols in use can result in a wide elemental carbon-to-total carbon variation by up to a factor of five. In Europe, there is currently no standard procedure for determining the
OBJECTIVE: The concordance index (c-index) is the standard way of evaluating the performance of prognostic models in the presence of censored data. Constructing prognostic models using artificial neural networks (ANNs) is commonly done by training on error functions which are modified versions of the c-index. Our objective was to demonstrate the capability of training directly on the c-index and t
We present a validated protocol for manual segmentation of the thalamus on T1-weighted magnetic resonance imaging (MRI) scans using brain image analysis software. The MRI scans of five normal control subjects were randomly selected from a larger cohort recruited from Lund University Hospital and Landskrona Hospital, Sweden. MRIs were performed using a 3.0T Philips MR scanner, with an eight-channel
The purpose of this paper is to compare a collection of control variates for Monte Carlo-valuation of spread options on three assets with a view towards energy markets and to lay a foundation for continued research on control variates, e.g. combinations of control variates and adaption for quasi-Monte Carlo. The paper builds upon previous research on option pricing using Monte Carlo-simulation and
In a progressively globalized world the catapults of economic globalization, is in large, due to increased flows of foreign direct investments (FDI) across the world. FDI flows are considered essential vehicles for economic growth and development. The complex entities that embody a multinational company (MNC ) are often simplified to encompass either an exploitation approach of LDCs by MNCs or the
The aim of this thesis has been to investigate the legal conditions and process for triggering Credit Default Swaps, which are derivative instruments to shift credit risk exposure between parties in an underlying financial instrument. The condition is called credit event and a case study has been done on the Greek credit event in 2012. The thesis shows that there is a clear and robust framework o
This essay addresses the needs of so called ‘climate migrants’. It focuses exclusively on the relocation of the population of Kiribati, a small island nation in the Pacific Ocean whose very existence is threatened by the effects of climate change. With the principles of causality, morality, capacity and community, Miller’s Connection Theory provides the study with a framework for discussing the di
In this paper, we investigate evidence of market discipline from contingent convertible (CoCo) issues. Previous research has focused on the monitoring aspect of market discipline, by testing risk sensitivity of market prices (subordinated notes and debentures (SND)) to accounting measures of bank risk. We take a similar approach using CoCo spreads and additionally use issue specific features. We a
Title: Implementing Change In Organisations: A Study on Limiting Factors for Managers in the Service industry. Purpose: The overall purpose of this study is to have a deeper understanding of how change affects employees and an organisation and what are the factors could hinder such a change. This study will draw on the theory of Change Management, in particular, the model of Prosci ADKAR. Method
Though the diffusion of electric vehicle (EV) is high on the global agenda, and there are efforts to speed up the shift: some countries intend to ban the sale of internal combustion engine vehicles (ICEV), and some OEMs (original equipment manufacturers) have announced the goal of electrification, the diffusion of EV is slowly. Technological innovation theory explains that we need to harmonise tec
In this thesis, we introduce a theoretical framework that can act as a foundation when develop-ing and adopting a BYOD policy. Using BYOD within organizations is a growing concept and continues to evolve as technology gets better, cheaper and more advanced. Our literature study indicates that the biggest advantage in regard to implementation of BYOD is cost reduction, moving the actual cost to the
Purpose: The purpose of the study was to understand the key managerial challenges associated with Big Data. The research aimed to look at the possible obstacles that managers need to overcome while implementing Big Data. The main research question is : What are the main managerial challenges associated with Big Data and what steps are needed to overcome those? Methodology: Based on the concepts of
Sustainability has long been serving dominant political and economic interests under the guise of sustainable development. This political and economic co-option of sustainable development has given rise to a new slogan: “system change, not climate change”. Our crisis is no longer just an environmental one, but a structural one, in which our means of living have outdistanced the ends for which we l
