In this paper we are concerned with the convergence analysis of splitting methods for nonautonomous abstract evolution equations. We introduce a framework that allows us to analyze the popular Lie, Peaceman-Rachford and Strang splittings for time dependent operators. Our framework is in particular suited for analyzing dimension splittings. The influence of boundary conditions is discussed.

Abstract in UndeterminedThe popularity of the Internet and marketers' increased investments in Internet advertising have raised some questions concerning a marketer's power to influence children and young people's consumption through new media technology. This article, based on a recent explorative study of 15-year-old Swedish teenagers, aims to discuss their exposure-potential, actual, and percei

The purpose of this thesis has been to study biological and social factors of importance for Attention Deficit Hyperactivity Disorder (ADHD). Thirty children (age 6-11) with ADHD were examined with parent ratings, neurological examination, cognitive testing, cerebral blood-flow, and EEG. These children together with 14 other children the same age with ADHD, were video-taped during family-tasks be

Capabilities-based planning and capability assessment are high on the agendas of several countries and organisations as part of their risk management and emergency preparedness. Despite this, few definitions of capability exist, and they are not easily related to concepts such as risk, vulnerability and resilience. The aim of the present study was thus to broaden the scientific basis of the risk f

The transverse momentum (p(T)) spectra and ratios of identified charged hadrons (pi(+/-), K-+/-, p, (p) over bar) produced in root s(NN) = 200 GeV Au + Au and d + Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p(T) = 6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p(T) = 4 GeV/

Deputation compounds (DCs) are added to passive air samplers (PAS) prior to deployment to account for the wind-dependency of the sampling rate for gas-phase compounds. This correction is particularly useful for providing comparable data for samplers that are deployed in different environments and subject to different meteorological conditions such as wind speeds. Two types of PAS-the polyurethane

Based on the constructivist international relations (IR) approach, the authors study Sweden’s engagement with the DPRK as a unique case to understand motivations for engaging in a so-called fragile state. Besides having its embassy in Pyongyang and serving as a protecting power for the U.S., Sweden has provided capacity building programs for North Korean government officials and scholars. It has a

Reproductive events are associated with important physiologic changes, yet little is known about how reproductive factors influence long-term health in women. Our objective was to assess the relation of reproductive characteristics with all-cause and cause-specific mortality risk.

This study aimed at examine the number of planned and acute hospital admissions during 1 year among people 65+ and its relation to municipal care, outpatient care, multimorbidity, age and sex. Four thousand nine hundred and seven individuals having one or more admissions during 2001 were studied. Data were collected from two registers and comparisons were made between those having one, two and thr

This paper deals with the varying roles of producer services in economic transformation during the last 30 years in Sweden, and analyses unique longitudinal data on eight service sectors. The theoretical background for the analysis is inspired by the technology shift thesis of economic historians, and we show that the renewal and transformation of producer services has taken place later than for t

Despite a broad theoretical literature on multidimensional inequality and a widespread belief that welfare is not synonymous to income - not the least in a developing context - empirical inequality examinations rarely include several welfare attributes. We explore three techniques on how to evaluate multidimensional inequality using Zambian household data on consumption, education, health and land

Popular Abstract in Swedish Sambanden mellan kostens sammansättning och risk för hjärt-kärlsjukdom är i många fall oklara. En kost rik på fleromättade fettsyror har ansetts kunna ge skydd mot hjärt-kärlsjukdom, men resultaten från olika studier är motstridiga. En anledning till detta kan vara för att man inte har tagit hänsyn till de genetiska skillnader som finns mellan individer. Omega-3 och oIn previous studies, a high quality diet has been associated with a reduced risk of cardiovascular disease (CVD) compared to a low diet quality, and specific “healthy” diet components, such as polyunsaturated fatty acids (PUFAs), have been hypothesized to reduce the risk of CVD. However, results from epidemiological studies have been conflicting. This may be due to individuals having varied geneti

The logic of the two principal ways of defining a genre - the classificatory and the historical is described. The problems concerning the classificatory definitions are analyzed. The distinction natural language and meta-language is evoked,and the fact that natural languages is defying this distinction,always mixing the levels,the classificatory genres do not. The historical genres belong to the n

Summertime measurements of CO2 and CH4 fluxes were carried out over a range of high-arctic ecosystem types in the valley Zackenbergdalen since 1996 using both chamber and eddy covariance methodology. The net ecosystem CO2 exchange and CH4 flux data presented reveal a high degree of inter-annual variability within the dominant vegetation types in the valley, but also show distinct differences betwe

Det övergripande syftet med avhandlingen var att belysa och kontextualisera fysioterapeutiska insatser för personer med schizofreniforma psykoser utifrån aktuell forskning om psykomotorisk funktion och självmedvetande. Självmedvetandeforskning, både experimentell och fenomenologisk, kopplar de mest grundläggande självmedvetandenivåerna till vårt kroppsliga ursprung; hur vi via den sensomotoriska f

This paper takes issue with a recent proposal due to Shogenji (Synthese 184:29-48, 2012). In his paper, Shogenji introduces J, a normatively motivated formal measure of justification (and of confirmation), and then proceeds to recruit it descriptively in an explanation of the conjunction fallacy. We argue that this explanation is undermined by the fact that it cannot be extended in any natural way

In Sweden and in other countries, building owners are encouraged to help reduce energy consumption, both in order to contribute to national energy saving goals and, in terms of their own interests, to reduce the costs of heating and operation of the building. However, it is important to pursue the most optimal strategy available so as to achieve cost-effective energy usage while simultaneously mai

Introduction The incidence of perforated peptic ulcer remains high in low and middle-income countries. Mortality can be significant, and early surgical management with careful evaluation of pre-operative risk factors is essential. The purpose of this study was to describe the clinical outcomes of surgical treatment for perforated peptic ulcer disease in Liberia and to explore risk factors for adve
