The sharing economy is an emerging niche for innovation capable of disrupting established socio-technical and economic regimes. Because of this potential to cause radical changes in a wide array of domains, research in multiple disciplines addressing various aspects entailing this phenomenon is proliferating. In this emerging body of literature, the understanding and framing of the sharing economy
OBJECTIVE: To determine whether probiotic prophylaxes reduce the odds of Clostridium difficile infection (CDI) in adults and children. DESIGN: Individual participant data (IPD) meta-analysis of randomized controlled trials (RCTs), adjusting for risk factors. METHODS: We searched 6 databases and 11 grey literature sources from inception to April 2016. We identified 32 RCTs (n=8,713); among them, 18
Background: To assess the quality of life of people with dementia, measures are required for self-rating by the person with dementia, and for proxy rating by others. The Quality of Life in Alzheimer's Disease scale (QoL-AD) is available in two versions, QoL-AD-SR (self-rating) and QoL-AD-PR (proxy rating). The aim of our study was to analyse the inter-rater agreement between self- and proxy rating
MOTIVATION: Missing data present a pervasive challenge in data analysis, potentially biasing outcomes and undermining conclusions if not addressed properly. Missing data are commonly classified into Missing Completely at Random (MCAR), Missing at Random (MAR), and Missing Not at Random (MNAR). While MCAR poses a minimal risk of data distortion, both MAR and MNAR can seriously affect the results of
The combustion of conventional Jet A, alongside two alternative jet fuels, C1 and C5, is simulated with Large Eddy Simulations (LES) in a generic single-cup spray combustor during idle and cruise conditions. The spray is modeled using Lagrangian particle tracking and the combustion chemistry of each fuel is modeled by skeletal reaction mechanisms. The volatility and atomizability of each fuel dire
OBJECTIVES: The efficacy of long-term opioid therapy (LTOT) in treating patients with chronic non-cancer pain (CnCP) is questionable, and the potential risks of adverse effects are well established. The aims were as follows: (1) compare characteristics in patients exposed to LTOT vs non-exposed. (2) Regarding opioid-exposed patients, describe characteristics of patients with risk factors for opioi
Background: Eating disorders significantly impact physical health and have negative psychosocial consequences. The global burden of anorexia nervosa and bulimia nervosa among young females is estimated to account for 1.9 million disability-adjusted life years. Early identification of disordered eating attitudes is critical for preventing the progression to more severe forms of eating disorders; ho
Background: Desmoplastic melanoma (DM) is a rare subtype, accounting for less than 5% of primary cutaneous invasive melanomas. DM often arises in chronically sun-exposed skin, in older individuals. While the incidence of cutaneous melanoma has increased globally, trends specific to DM are less documented and studies on survival outcomes for DM are inconsistent. Objectives: To study patient and tum
AIMS/HYPOTHESIS: The aim of this work was to explore associations between type 1 diabetes progression from stages 1 or 2 to stage 3 and interacting ligand-receptor complexes of HLA class I (HLA-I) and KIR gene products.METHODS: Applying next-generation sequencing technology to genotype HLA-I genes (HLA-A, -B, -C) and KIR genes (KIR2DL1, KIR2DL2, KIR2DL3, KIR2DL4, KIR2DL5, KIR2DS1, KIR2DS2, KIR2DS3
The current investigation explores the surface effects of quasiatomic layer etching (Q-ALE) of silicon (Si), focusing on the interplay of process parameters, such as Ar+ ion energy, and their impact on etch rate, surface roughness, and material damage. Using a chlorine-based reactive ion etching tool at varying radio frequency bias voltages, the ion energy distribution and etching characteristics
Background: Several studies have investigated the association between metabolic syndrome (MetS) and physical activity (PA). However, further research is needed using objective measures of PA in free-living conditions, while also accounting for the time-variant nature of MetS. This study aimed to: (1) investigate the association between wearable device-measured step count and 5-year MetS incidence
Objective: To investigate the association of different aspects of cognitive impairment, depression and anxiety with walking difficulties in daily life in persons with mild PD.Background: Walking difficulties in daily life are common among persons with Parkinson’s disease (PD) and may cause falls and near falls, limitations in activity, restrictions in participation and decrease in quality of life.
Dead wood is a key element in forest ecosystems and a wide range of organisms are dependent on this substrate for development and reproduction. Saproxylic beetles are important decomposers of dead wood and serve as food for many organisms. Due to the significant forestry-related decrease of dead wood in rural areas, many species of saproxylic beetles are considered threatened. Thus, other spaces h
Leaving a sustainable society for our children is considered an arbitrary goal for the environmental work that is currently taking place in Sweden. Today, 140 million tonnes of non-hazardous waste is generated in Sweden, which is unsustainable. 31% of the non-hazardous waste is traced to the construction industry, the mining industry excluded. Today, the waste is an unused resource that is purchas
Outdoor climate has considerable impact on the indoor climate and it is therefore important to adapt the buildings to the climate. This thesis shows how to improve indoor climate in a climate which it is hot, dry in the summer and cold in the winter. My investigative unit is a middle class house in the town Baalbek in Lebanon and the purpose of the study is to come up with proposals on possible so
Popular science Using remote sensing to assess drought in Somalia Somalia, the country in East Africa in a region referred to as Horn of Africa is in a civil war, conflict and unrest since 1991. The prolonged conflict increases the impact of droughts in the country which is already prone to drought continuously. The country is frequently exposed to drought, occurring moderately every 3-4 years a
Shale gas extraction commonly known as fracking had support from the UK government with their ‘all out for shale’ policy. Despite this industry has struggled to establish itself mainly due to strong opposition from communities concerned about environmental and health impacts. Most research into the impacts of fracking is concerned with either environmental degradation or physical health impacts wh
Stjärnor sägs vara astronomins tidskapsel, genom att studera stjärnor kan vi bättre förstå många fenomen. Stjärnor är en viktig del av vårt universum från det att de skapas till det att de dör. De berikar vårt universum med olika grundämnen som krävs för att planeter ska bildas och för att liv ska uppstå. Det verkar då självklart varför man vill undersöka och förstå alla aspekter kring stjärnbildnThis is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. Matson, during an internship in collaboration with the Swedish National S
