Social entrepreneurship research highlights the collaborative nature of social entrepreneurial efforts. Further, acknowledging the embeddedness of social ventures in the wider socio-economic and cultural context, the literature stresses the need to move our analysis from the micro-level of intra-organisational practices to the meso-level of inter-organisational dynamics. To answer to these calls,
Among the many unique flight behaviours of Common Swifts Apus apus, the most puzzling may be their ascents to high altitudes during both dusk and dawn. Twilight ascents have been hypothesized to be functionally related to information acquisition, including integration of celestial orientation cues, high-altitude visual landmarks and sampling of weather conditions. However, their exact purpose rema
Models suggest that climate change mitigation now depends on negative emissions, i.e. the large‐scale removal of carbon dioxide from the atmosphere. This assumption has been criticised in the climate policy literature for being unfeasible and unjust. This article asks how critical scholars can make sense of, and contribute to these debates. It suggests that negative emissions can be conceived of a
Selling goods and providing services in public spaces is one of the most accessible occupations for many urban poor. However, use of public space for such occupations is often prohibited by local regulations, excluding street vendors from legally using this space for their survival. While significant research has been devoted to state efforts to control informality, less is known about the everyda
Wettability gradient in radial direction and evaporation rate gradient can cause droplet motion on a solid surface. Here a theoretical model is proposed. Besides, an equation of droplet velocity is derived on a solid surface. We consider the wettability and evaporation rate gradients are mainly caused by the chemical composition and surface roughness, only along the radial direction. Surface tensi
Cd13-x;In7Sb10 (x≈2.7, Y≈ 1.5) was synthesized in the form of millsized crystals from reaction mixtures containing excess cadmium. The intermetallic compound crystallizes in the rhombohedral space group R3m with α = 12.9704(4), c= 12.9443(5) Å, V= 1886.0(1) Å3, Z=3 and is isostructural to thermoelectric ß-Zn 4Sb3 and ßCd4Sb3. However, in contrast to these last two compounds Cd13-xInySb 10 is free
This study scrutinizes gender differences in adolescent problem behaviour and its potential determinants, simultaneously taking into account the individual and contextual level, including personality, family and country characteristics. Using the 2010 EU Kids Online Survey, we estimate multilevel models on 18,027 individuals from 24 European countries. In line with earlier research, we find that b
We present high statistics MC calculations of the static potential in three-dimensional SU(2) for a wide range of β values on a 243 lattice. The deviations from area law are unambiguously demonstrated by use of 2nd lattice R derivative. After a clear crossover at β=4.5 the data show signs of an effective string roughening up to β=6.5, while scaling is not strictly obeyed in this interval. Pure fer
Purpose In this paper, the authors challenge traditional views of project management and sustainable development as purportedly complementing each other. Rather, the authors apply a projectification perspective from a multi-disciplinary approach to sustainable development. The purpose of this paper is to demonstrate how we can better understand the interface between projects and sustainable devel
Apolipoprotein M (apoM) in human plasma is mainly associated with HDL. A retained signal peptide anchors apoM to the lipoproteins. To investigate the role of the signal peptide in the transfer of apoM from the synthesizing cell to the lipoproteins, wildtype apoM cDNA and the Q(22)A mutant, introducing a signal peptidase cleavage site, were used to stably transfect HEK293 cells, which intrinsically
The neutrophil is a key player in immunity, and its activities are essential for the resolution of infections. Neutrophil-pathogen interactions usually trigger a large arsenal of antimicrobial measures that leads to the highly efficient killing of pathogens. In neutrophils, the phagocytic process, including the formation and maturation of the phagosome, is in many respects very different from that
The treatment of meniscus tears and anterior cruciate ligament (ACL) injuries are mainly considered as symptomatic. Meniscus tears can be divided into traumatic and degenerative tears, with different outcomes. A displaced meniscus with a locked knee constitutes an acute indication for arthroscopic surgery. A degenerative tear with mechanical symptoms also represents an indication for surgery. The
Cognitive and motivational effects of more neutral or androgynous-looking virtual characters versus more pronouncedly feminine-looking or masculine-looking virtual characters are explored. In a user study, 158 students aged 17-19 encountered four virtual characters that were visually manipulated to represent gender stereotypicality versus androgyny. One aim was to explore students’ attitudes towar
The paper studies the local solvability and subellipticity for square systems of principal type. These are the systems for which the principal symbol vanishes of first order on its kernel. For systems of principal type having constant characteristics, local solvability is equivalent to condition (Ψ) on the eigenvalues. This is a condition on the sign changes of the imaginary part along the oriente
