We conduct a comprehensive review of embeddedness in entrepreneurship research. Although the term “embeddedness” is frequently used in this field of study, less is known about the ways in which it is operationalized and applied. Using criterion sampling, we analyse 198 articles in order to investigate how embeddedness is conceptualized and what role it plays in the extant entrepreneurship literatu
IntroductionAn important hallmark of cancer is escaping the immune system. Despite advances in immunotherapy, only a subset of patients experiences clinical benefits. It was shown that adoptive T cell or checkpoint inhibition therapy rely on the presence of conventional dendritic cells type 1 (cDC1). cDC1 excel in recruiting and priming protective CD8+ T cells through cross-presentation. However,
BACKGROUND: There has been a growing body of evidence associating consumption of ultra-processed foods (UPF) with adverse health outcomes including depression, cardiovascular disease, all-cause mortality. However, whether UPF are associated with dementia is unknown. The authors investigated the associations between UPF and dementia incidence in UK biobank.METHODS: We included 72,083 participants (
This paper offers a two-zone, physical, NOx model with low computational cost, implemented in C on an embedded system. The model is able to compute NOx-emission formation with high time resolution during an engine cycle. To do this the model takes cylinder pressure and injected fuel amount as inputs and produces NO concentration as output. The model as such is not new, nevertheless the physical ba
I denna forskningsöversikt kartläggs svenskproducerad och kvalitetsgranskad forskning om svensk forskarutbildning i syfte att illustrera forskningsfältets fysiska och vetenskapliga formering 2000–2020. Databasen Swepub användes för att identifiera licentiatavhandlingar, doktorsavhandlingar och refereegranskade artiklar som sedan analyserades med deskriptiv statistik och tematisk analys. Fältets fyIn this scoping review we map Swedish research on Swedish doctoral education in order to illustrate the physical and scientific configuration of the field from 2000 to 2020. The database Swepub was used to identify licentiate theses, doctoral theses, and peer reviewed articles. Subsequently the material was analysed through descriptive statistics and thematic analysis. The physical configuration o
The Personal Software Process (PSP) is launched as a means for improving software development capabilities for the individual engineer. It is proposed that it should be used in software engineering curricula: some authors propose it to be used already during the first student year: The PSP course is successfully given for graduate students at Lund University since 1996. During the spring semester
On a planetary scale, the D/H ratio on Mars is a key diagnostic for understanding the past history of water on the planet; locally, it can help to constrain the sources and sinks of water vapor through the monitoring of condensation and sublimation processes. To obtain simultaneous measurements of H2O and HDO lines, we have used the Echelle Cross Echelle Spectrograph (EXES) instrument aboard the S
In solid mechanics, linear structures often exhibit (local) nonlinear behavior when close to failure. For instance, the elastic deformation of a structure becomes plastic after being deformed beyond recovery. To properly assess such problems in a real-life application, we need fast and multi-query evaluations of coupled linear and nonlinear structural systems, whose approximations are not straight
Background Patients with acute intracerebral hemorrhage who are receiving factor Xa inhibitors have a risk of hematoma expansion. The effect of andexanet alfa, an agent that reverses the effects of factor Xa inhibitors, on hematoma volume expansion has not been well studied. Methods We randomly assigned, in a 1:1 ratio, patients who had taken factor Xa inhibitors within 15 hours before having an a
Background: Risky sexual behavior (RSB) is one of the major youth sexual and reproductive health problems globally, including in Ethiopia. RSB among youth increases the risk of HIV infection, other sexually transmitted infections (STIs), unintended pregnancy, and unsafe abortion. Therefore, the aim of this study was to examine RSB and its associated factors among university students in Ethiopia. M
Micron-sized aluminum (Al) particles have recently been proposed as promising carbon-free energy carriers. To facilitate the application of micron-sized Al particles as fuel in practical energy generation system, this study experimentally investigates the underlying mechanisms of the ignition, stabilization and particle-particle collision in lifted Al particle cloud flames. High-resolution shadowg
BACKGROUND: Obesity, assessed by body mass index (BMI), is an established risk factor for 13 cancers. We aimed to identify further potential obesity-related cancers and to quantify their association with BMI relative to that of established obesity-related cancers.METHODS: Using Cox regression models on 4,142,349 individuals in Sweden (mean age 27.1 years at weight measurement), we calculated hazar
The processes responsible for the formation of Earth's most conspicuous diversity pattern, the latitudinal diversity gradient (LDG), remain unexplored for many clades in the Tree of Life. Here, we present a densely sampled and dated molecular phylogeny for the most speciose clade of damselflies worldwide (Odonata: Coenagrionoidea) and investigate the role of time, macroevolutionary processes, and
This work establishes a computational framework for the quantification of the effect of uncertainty of material model parameters on extremal stress triaxiality and Lode angle values in plastically deformed devices, whereby stress triaxiality and Lode angle are accepted as key indicators for damage initiation in metal forming processes. Attention is paid to components, the material response of whic
The electronic structure of high-quality van der Waals multiferroic CuCrP2S6 crystals was investigated by applying photoelectron spectroscopy methods in combination with DFT analysis. Using X-ray photoelectron and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy at the Cu L2,3 and Cr L2,3 absorption edges, we determine the charge states of ions in the studied compound. Analyzing the
PurposeIn oculoplastic surgery the eyelid tissue is frequently stretched in order to repair defects after tumor surgery. However, there is a paucity of research regarding how stretching affects eyelids. The purpose of this study was to gain insight into how traction force affects eyelid stretch as well as tissue perfusion, using a laser-based in vivo monitoring technique.MethodLower-lid pentagonal
