Disruptive Network Innovation in Free Guided Tours

This article provides an analysis on how disruptive innovation is spurred by the dynamics of digital and analogue networks in the sharing economy. The analysis builds on a free guided tour company in Copenhagen. Data is collected in a bottom-up reiterative process, drawing on theories on disruptive innovation and network theory. Between 2013 and 2016, one of the free tour companies in Copenhagen w

Search for electroweak production of supersymmetric states in scenarios with compressed mass spectra at s =13 TeV with the ATLAS detector

A search for electroweak production of supersymmetric particles in scenarios with compressed mass spectra in final states with two low-momentum leptons and missing transverse momentum is presented. This search uses proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2015-2016, corresponding to 36.1 fb-1 of integrated luminosity at s=13 TeV. Events with same-

An analytical solution to study substrate-microbial dynamics in soils

We provide an approximate analytical solution for the substrate-microbial dynamics of the organic carbon cycle in natural soils under hydro-climatic variable forcing conditions. The model involves mass balance in two carbon pools: substrate and biomass. The analytical solution is based on a perturbative solution of concentrations, and can properly reproduce the numerical solutions for the full non

The positive net radiative greenhouse gas forcing of increasing methane emissions from a thawing boreal forest‐wetland landscape

At the southern margin of permafrost in North America, climate change causes widespread permafrost thaw. In boreal lowlands, thawing forested permafrost peat plateaus (‘forest’) lead to expansion of permafrost‐free wetlands (‘wetland’). Expanding wetland area with saturated and warmer organic soils is expected to increase landscape methane (CH4) emissions. Here, we quantify the thaw‐induced increa

Dickkopf-related protein 1 and gremlin 1 show different response than frizzled-related protein in human synovial fluid following knee injury and in patients with osteoarthritis

Objective: To explore the involvement of the wingless-type MMTV integration site (WNT) and bone morphogenetic protein (BMP) antagonists dickkopf-related protein 1 (DKK1), frizzled-related protein (FRZB) and gremlin 1 (GREM1) in knee injury and osteoarthritis (OA). Design: The antagonists were immunoassayed in synovial fluid from a cross-sectional cohort of nine knee healthy reference subjects, pat

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis of 36 blood group alleles among 396 Thai samples reveals region-specific variants

BACKGROUND: Blood group phenotype variation has been attributed to potential resistance to pathogen invasion. Variation was mapped in blood donors from Lampang (northern region) and Saraburi (central region), Thailand, where malaria is endemic. The previously unknown blood group allele profiles were characterized and the data were correlated with phenotypes. The high incidence of the Vel-negative

Public talk on personal troubles : A study on interaction in radio counselling

Denna doktorsavhandling undersöker samtal om personliga problem i mötet med en specialist i radio. I synnerhet handlar studien om den dynamiska process då förståelse skapas – när upplevelser av personliga bekymmer förklaras och definieras som problem av särskilda slag. Denna meningsskapande process undersöks i detalj så som den utspelar sig i dialoger i radio och mellan programdeltagare och radiolThe dissertation examines how personal troubles are talked about in an encounter with a professional on the public arena of radio broadcasting, where the professional has to meet the challenge of making professional advice not only useful for the person seeking help, but also relevant or interesting for the radio audience. The study explores the dynamic process of shaping an understanding of probl

Maternal immunization increases nestling energy expenditure, immune function, and fledging success in a passerine bird

Female birds transfer maternally derived antibodies (matAb) to their nestlings, via the egg yolk. These antibodies are thought to provide passive protection, and allow nestlings to avoid the costs associated with mounting an innate immune response. To test whether there is an energetic benefit to nestlings from receiving matAb, we challenged adult female tree swallows (Tachycineta bicolor) prior t

Refugee Status Determination in the Context of 'Natural' Disasters and Climate Change : A Human Rights-Based Approach

This thesis is concerned with refugee status determination (RSD) in the context of ‘natural’ disasters and climate change. Considering evidence that the legal predicament of people who seek recognition of refugee status in this connection has been inconsistently addressed by judicial bodies in leading refugee law jurisdictions, and identifying theoretical as well as doctrinal impediments to a cleaThis thesis is concerned with refugee status determination (RSD) in the context of ‘natural’ disasters and climate change. Considering evidence that the legal predicament of people who seek recognition of refugee status in this connection has been inconsistently addressed by judicial bodies in leading refugee law jurisdictions, and identifying theoretical as well as doctrinal impediments to a clea

A process for estimating minimum feature size in selective laser sintering

Purpose: Manufacturer specifications for the resolution of an additive manufacturing (AM) machine can be ten times smaller (more optimistic) than the actual size of manufacturable features. Existing methods used to establish a manufacturable design rule-set are conservative piecewise-constant approximations. This paper aims to evaluate the effectiveness of a first-order model for producing improve

Emanuel Swedenborg : Liv och tänkande

Emanuel Swedenborg (1688–1772) var en svensk naturfilosof, verksam som assessor i Bergskollegium, sedermera bibeltolkare, andeskådare och teolog. Hans kontrastrika liv, från naturvetenskap till teologi, från rationalism till mystik, från matematik till andeskådande, har förbryllat och fascinerat många. I dag är han en av de mest internationellt kända och översatta svenska författarna genom tiderna

Sustainable venture capital - Catalyst for sustainable start-up success?

To address global sustainability challenges, major investments are required in sustainable businesses that deliver triple bottom line results. Although interest in sustainable businesses is on the rise, these businesses are not yet widespread. Venture capital investment has a key role to play in the development of sustainable start-ups. The research area of 'sustainable' venture capital is still e

Frames of reference in multibody dynamics

In this paper, a discussion is undertaken concerning the use of so-called floating frames of reference in the calculation of the kinetic and elastic energies of parts in a multibody system. The use of floating frames may simplify the calculation of the elastic energy, although sometimes at the expense of more elaborate expressions for the kinetic energy. These expressions may involve terms that co
