Towards a Prescriptive Framework of Sharing Platform Models

While research on the sharing economy has sought to illustrate business models within the sharing economy, the focus of this research has largely been on unicorns Airbnb, Uber, and other technology-driven market platforms. Furthermore, inductive approaches to study business models in the sharing economy fail to distinguish between the multitude of practices – in particular, those practices that pr

Novel Pharmacological Targets for Combat PTSD-Metabolism, Inflammation, The Gut Microbiome, and Mitochondrial Dysfunction

INTRODUCTION: Current pharmacological treatments of post-traumatic stress disorder (PTSD) have limited efficacy. Although the diagnosis is based on psychopathological criteria, it is frequently accompanied by somatic comorbidities and perhaps "accelerated biological aging," suggesting widespread physical concomitants. Such physiological comorbidities may affect core PTSD symptoms but are rarely th

HFSZEEMAN95—A program for computing weak and intermediate magnetic-field- and hyperfine-induced transition rates

HFSZEEMAN95 is an updated and extended Fortran 95 version of the HFSZEEMAN program (Andersson and Jönsson, 2008). Given relativistic atomic state functions generated by the GRASP2018 package (Fischer et al., 2019), HFSZEEMAN95 together with the accompanying Matlab/GNU Octave program MITHIT allows for: (1) the computation and plotting of Zeeman energy splittings of magnetic fine- and hyperfine stru

Life Satisfaction in Persons With Late Effects of Polio : A Test-Retest Reliability Study

Background: The Life Satisfaction Questionnaire (LiSat-11), including one global item and 10 domain-specific items, is used to evaluate life satisfaction in persons with the late effects of polio (LEoPs). However, there is a lack of knowledge about its psychometric properties. Objective: To evaluate the test-retest reliability of the LiSat-11 and the associations between the global and domain-spec

Hip displacement and dislocation in a total population of children with cerebral palsy in Scotland

AIMS: The purpose of this study was to compare the prevalence of hip displacement and dislocation in a total population of children with cerebral palsy (CP) in Scotland before and after the initiation of a hip surveillance programme. PATIENTS: A total of 2,155 children with CP are registered in the Cerebral Palsy Integrated Pathway Scotland (CPIPS) surveillance programme, which began in 2013. Phys

Backward lasing of singly ionized nitrogen ions pumped by femtosecond laser pulses

We report on the observation of backward lasing at 391.4 nm of nitrogen ions pumped by linearly polarized intense femtosecond pulses at 800 nm. The strongly enhanced spectral intensity at 391.4 nm, as well as the amplification of an externally injected backward seeding pulse, confirm that the backward 391.4 nm signal is due to optical amplification in the nitrogen gas plasma. Compared to the forwa

Re-evaluation of HER2 status in 606 breast cancers—gene protein assay on tissue microarrays versus routine pathological assessment

Human epidermal growth factor receptor 2 (HER2) status in breast cancer is routinely determined through immunohistochemistry (IHC) and/or in situ hybridisation (ISH) performed on whole tissue sections (WS). The purpose was to evaluate whether a gene protein assay (GPA) combining IHC with ISH, performed on breast cancer tissue microarray (TMA), is suitable for large-scale retrospective HER2 status

On phase retrieval via matrix completion and the estimation of low rank PSD matrices

Given underdetermined measurements of a positive semi-definite (PSD) matrix X of known low rank K, we present a new algorithm to estimate X based on recent advances in non-convex optimization schemes. We apply this in particular to the phase retrieval problem for Fourier data, which can be formulated as a rank 1 PSD matrix recovery problem. Moreover, we provide a theory for how oversampling affect

Law, Society and Corruption: Lessons from the Central Asian Context

This book presents new socio-legal perspectives and insights on the social life of corruption and anti-corruption in authoritarian regimes.This book takes up the case of Uzbekistan—an authoritarian regime in Central Asia and one of the most corrupt countries in the world according to Transparency International’s Corruption Perceptions Index—and examines the corruption that developed in a tightly c

Decentralized Massive MIMO Processing Exploring Daisy-Chain Architecture and Recursive Algorithms

Algorithms for Massive MIMO uplink detection and downlink precoding typically rely on a centralized approach, by which baseband data from all antenna modules are routed to a central node in order to be processed. In the case of Massive MIMO, where hundreds or thousands of antennas are expected in the base-station, said routing becomes a bottleneck since interconnection throughput is limited. This

Perspectives in fluid biomarkers in neurodegeneration from the 2019 biomarkers in neurodegenerative diseases course - A joint PhD student course at University College London and University of Gothenburg

Until relatively recently, a diagnosis of probable Alzheimer's disease (AD) and other neurodegenerative disorders was principally based on clinical presentation, with post-mortem examination remaining a gold standard for disease confirmation. This is in sharp contrast to other areas of medicine, where fluid biomarkers, such as troponin levels in myocardial infarction, form an integral part of the

Neonatal BCG vaccination and child survival in TB-exposed and TB-unexposed children : A prospective cohort study

Objectives To assess the association between neonatal BCG vaccination and mortality between 28 days and 3 years of age among tuberculosis (TB)-exposed and TB-unexposed children. Design Prospective cohort study. Setting Bandim Health Project runs an urban Health and Demographic Surveillance site in Guinea-Bissau with registration of mortality, vaccination status and TB cases. Participants Children

When objects are talking : How tacit knowing becomes explicit knowledge

The objective of this paper is to build a model of how tacit knowing is externalised and becomes reflected external knowledge. Knowledge Management (Nonaka, 1991, 1994; Nonaka, Toyama, & Konno, 2000) is an important field in Business Administration. Based on the model provided by Nonaka and his colleagues (Nonaka, 1994; Nonaka & Takeuchi, 1995; Nonaka et al., 2000) researchers and practiti
