Family matters: family social capital in immigrants’ entrepreneurial opportunity creation processes

This paper conducts an inductive case study to develop theory on the role of family in the host and home country in the process of immigrant entrepreneurs’ creation of entrepreneurial opportunities. We employ the perspectives of the opportunity creation process and family social capital. We conducted four cases of immigrant entrepreneurs from Lebanon, Syria, Cameroon and Mexico, that launched busi

The neuroprotective effects of 17β-estradiol pretreatment in a model of neonatal hippocampal injury induced by trimethyltin

Hippocampal dysfunction plays a central role in neurodevelopmental disorders, resulting in severe impairment of cognitive abilities, including memory and learning. On this basis, developmental studies represent an important tool both to understanding the cellular and molecular phenomena underlying early hippocampal damage and to study possible therapeutic interventions, that may modify the progres

Opportunity creation as a mixed embedding process: A study of immigrant entrepreneurs in Sweden

Entrepreneurial opportunities are frequently noted and addressed in the literature of immigrant entrepreneurship; however, little is known about how these entrepreneurial opportunities come into existence and how immigrant entrepreneurs create such opportunities. The purpose of this thesis is to examine why and how immigrant entrepreneurs create entrepreneurial opportunities through embedding proc

Family embeddedness in immigrants' entrepreneurial opportunity creation process

Family contributes to immigrant entrepreneurs’ business development in different ways. Family provides financial resources, accept lower salaries and offer volunteer based work. However, there is a lack of research investigating the role of family in the oppoertunity creation process.Thereby the aim of this paper is to explore how family influences the process of entrepreneurial opportunity create

Nano-scale Infrared Imaging of β-sheet Structures in Synaptic Junctions of Primary Neurons Isolated from Transgenic Mice

Aβ is a class of aggregation-prone proteins, which may misfold into stable, β-sheet rich fibrils. Aβ is linked to the development of synaptic pathology in Alzheimer's disease (AD). However, a main question in the AD field is how Aβ contributes to AD neuropathology? Up to now there is little evidence for protein structural changes in diseased neuron. Our aim is to study the distribution of β-sheet

Association between paternal smoking at the time of pregnancy and the semen quality in sons

BACKGROUND: Maternal smoking during pregnancy has repeatedly been associated with decreased sperm counts in sons. Nevertheless, our team recently detected a lower total sperm count in the sons of smoking fathers as compared to sons of non-smoking fathers. Since paternal and maternal tobacco smoking often coincide, it is difficult to discriminate whether effects are mediated paternally or maternall

Heat Loss Analysis for Various Piston Geometries in a Heavy-Duty Methanol PPC Engine

Partially premixed combustion (PPC) in internal combustion engine as a low temperature combustion strategy has shown great potential to achieve high thermodynamic efficiency. Methanol due to its unique properties is considered as a preferable PPC engine fuel. The injection timing to achieve methanol PPC conditions should be set very close to TDC, allowing to utilize spray-bowl interaction to furth

Solvability of subprincipal type operators

In this paper we consider the solvability of pseudodifferential operators in the case when the principal symbol vanishes of order k ≥ 2 at a nonradial involutive manifold Σ2. We shall assume that the operator is of subprincipal type, which means that the kth inhomogeneous blowup at Σ2 of the refined principal symbol is of principal type with Hamilton vector field parallel to the base Σ2, but trans

Effect of Piston Geometry on Stratification Formation in the Transition from HCCI to PPC

Partially premixed combustion (PPC) is an advanced combustion strategy that has been proposed to provide higher efficiency and lower emissions than conventional compression ignition, as well as greater controllability than homogeneous charge compression ignition (HCCI). Stratification of the fuel-air mixture is the key to achieving these benefits. The injection strategy, injector-piston geometry d

A revised ontogeny of the early Ordovician trilobite Leptoplastides salteri (Callaway, 1877)

The ontogeny of the pelturine olenid trilobite Leptoplastides salteri (Callaway, 1877) from the Shineton Shales, Shropshire, England, was first described in 1925 by Frank Raw. Since that time, scanning electron microscopy and other new technologies have revealed many more details of structure, of early developmental stages in particular, than were available to Raw. Whereas protaspides are not pres

What Encourages Academic Staff to Engage in Systematic, Sustained Change in Teaching Practices?

Representing an international, multi-institutional research team, the panel presents a theoretical framework for understanding what prompts academic staff/faculty to change towards sustained use of pedagogies that make a meaningful difference in student learning. The theory grows out of a synthesis of literature on: the role of leadership and resources in emerging changes to teaching practices (Gi

Review findings included diminished coronary flow reserve after surgery in children with congenital heart disease and inflammation

Aim: The aim of this review was to develop a deeper knowledge of the physiology of coronary blood flow and coronary flow reserve in young patients with congenital heart disease and inflammatory diseases. Methods: We searched for papers published in English on coronary blood flow and coronary flow reserve using the PubMed and Google search databases. This identified 42 papers extending back to 1976

Osteoarthritis-related walking disability and arterial stiffness-results from a cross-sectional study

OBJECTIVES: To compare 6 minute walking distance (6MWD) in a population-based osteoarthritis (OA) cohort with matched peers from the general population, and to explore the associations between walking ability and CVD risk (arterial stiffness) in the OA cohort.DESIGN: This cross-sectional study included participants (40-80 years) who self-reported OA (n=500) in a population-based study and age- and

A hospital-based observational cohort study exploring pain and biomarkers in patients with hand osteoarthritis in Norway : The Nor-Hand protocol

INTRODUCTION: We have limited knowledge about the underlying disease mechanisms and causes of pain in hand osteoarthritis (OA). Consequently, no disease-modifying drug exists, and more knowledge about the pathogenesis of hand OA is needed, as well as a validation of different outcome measures. Our first aim of this study is to explore the validity of various imaging modalities for the assessment o
