Begreppet plattformar har under de senaste åren seglat upp som ett av de mest centrala begreppen i den digitala ekonomin. Digitala plattformar möjliggör mängder av nya, effektiva sätt att organisera samhället – med långtgående konsekvenser för en rad centrala samhällsfunktioner. Detta ställer en rad frågor om medbestämmande och reglering, om innovationens förutsättningar och hur en plattformsmedve
Target Temperature Management (TTM) is standard care following out of hospital cardiac arrest (OHCA). The aim of the study was to evaluate if treatment temperature (33°C or 36°C) or other predefined variables were associated with the occurrence of bleeding in the TTM study. This study is a predefined, post hoc analysis of the TTM trial, a multinational randomized controlled trial comparing treatme
The use of interactive visualization techniques in Digital Humanities research can be a useful addition when traditional automated machine learning techniques face difficulties, as is often the case with the exploration of large volumes of dynamic—and in many cases, noisy and conflicting—textual data from social media. Recently, the field of stance analysis has been moving from a predominantly bin
INTRODUCTION: Preeclampsia (PE) is an important cause of fetal and maternal morbidity and mortality. It is considered a two-stage disease, the first stage characterized by a defect placentation and the second stage by maternal manifestations. Details of the patho-physiology behind the transition from stage one to stage two remain unclear.OBJECTIVE: Was to study first trimester placental gene expre
BACKGROUND: Depressive disorders are associated with immune system alterations that can be detected in the blood. Cytokine concentrations in cerebrospinal fluid (CSF) and their relationship to aspects of suicidality have previously not been investigated. METHODS: We measured interleukin-1beta, interleukin-6 (IL-6), interleukin-8, and tumor necrosis factor-alpha (TNF-alpha) in CSF and plasma of sui
The diffractive photoproduction of J/psi mesons is measured with the HI detector at the ep collider HERA using an integrated luminosity of 78 pb(-1). The differential cross section dsigma(gammap --> J/psiY)/dt is studied in the range 2 < < 30 GeV2, where t is the square of the four-momentum transferred at the proton vertex. The cross section is also presented as a function of the photon-proton cen
Popular Abstract in Swedish Denna doktorsavhandling består av fyra fristående artiklar. Artiklarna har det gemensamt att de alla använder Bayesiansk ekonometri, i kombination med s.k. Markov chain Monte Carlo (MCMC) metoder, för att studera olika problem inom finansiell ekonomi. De första två artiklarna är ytterligare relaterade till varandra genom att de båda handlar om portföljvalsteori och skatThis PhD thesis consists of four separate papers. What these papers have in common is that Bayesian Econometrics, in combination with Markov chain Monte Carlo (MCMC) methods, is applied to study various problems in financial economics. The first two papers are further related in that they both deal with portfolio selection and estimation risk, as are the last two papers in that they both deal with
The aim of this study is to explore the use and perceived unfilled need for assistive technology (AT) for everyday life in three age-groups during the ageing process. Data on use and perceived unfilled need for AT from three age-groups were used; the very old age-group; 81-90, n=314, the oldest old age-group; 85-94, n=154 and younger agegroup, 67-71. The results show that the proportion of users h
In this paper we propose a test planning scheme for corebased 3D stacked integrated circuits where the total test cost for wafer sort of each individual chip and the test cost of the complete stack at package test is minimized. We use an Integer Linear Programming (ILP) model to find the optimal test cost, which is given as the weighted sum of the test time and the test access mechanism (TAM). As
Popular Abstract in Swedish INLEDNING – Människans hörsel är beroende av att öra, nervsystem och hjärna alla fungerar som de skall. Det inkluderar mellanörat; med hörselben och trumhinna, innerörat; med sina sinnesceller, hörselnerven och hörselcentrum i hjärnan. Det är välkänt att ändrat omgivningstryck påverkar örat - vi får till exempel alla lock i öronen och hör dåligt om vi inte kan tryckutjäResults from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. The focus is on the emergence of the pressure gradients betwe
After decades of development of information systems dedicated to health professionals, there is an increasing demand for personalized and non-hospital based care. An especially critical domain is cardiology: almost two third of cardiac deaths occur out of hospital, and victims do not survive long enough to benefit from in-hospital treatments. We need to reduce the time before treatment. But sympto
The infrastructure for the third generation of mobile telephony, UMTS, is under construction in Sweden. Within three years four operators were to build competing systems to cover 99,98 % of the population. The case of the 3G infrastructure illustrates how sustainability issues are handled in planning and environmental management, with conflicting goals between institutional levels and contradict
In order to qualify a subscriber loops for xDSL transmission, basic parameters like transfer function, scattering parameter S11 and characteristic impedance should be known. The aim of this paper is to present a test methodology for measurements of these basic parameters. The characteristic impedance is measured by open/short method and it is compared with the terminated measurement method defined
This paper describes a general picture of efforts to provide women with equal opportunity both on a national political level, and within academia. A report of recent activities within the newly formed National Division for Women in Physics within the Swedish Physical Society is also given
