This thesis aims to advance our understanding of how directors’ values influence board decision-making and firm behavior by developing and testing a model that integrates insights from behavioral perspectives on boards of directors and corporate governance. Ideally, boards engage in intensive and open discussions that utilize the full cognitive capacity of their members. However, in practice, they

Solution combustion synthesis (SCS) is a rapid and scalable synthetic pathway for producing metallic and oxide nanoparticles and thin films, resulting from the exothermic combustion between a metal cation, chelating organic fuel, and an oxidant. However, understanding the divergence in SCS between thin-film and unconfined bulk combustion, as well as in situ experiments probing the reaction progres

BACKGROUND:Detection of ischemia and intracranial hemorrhage (ICH) directly after endovascular thrombectomy (EVT) could enable earlier diagnosis and treatment. We evaluated whether post-EVT Sine Spin cone-beam computed tomography (CBCT) on the Siemens ARTIS Icono biplane system at the end of the procedure can predict ischemia and ICH on subsequent follow-up computed tomography (FUCT) within 48 hou

Background: Precise radiotherapy relies on accurately targeting tumours while minimising exposure to healthy tissue, yet patient and organ motion complicate treatment delivery. To address intra-fractional motion, multi-leaf collimator (MLC) tracking systems have recently been adopted, adapting beam shapes in real-time. The American Association of Physicists in Medicine (AAPM) Task Group 264 (TG-26

We consider random graphs on the set of N2 vertices placed on the discrete 2-dimensional torus. The edges between pairs of vertices are independent, and their probabilities decay with the distance ρ between these vertices as (Nρ)−1. This is a versatile example of an inhomogeneous random graph that is not of rank 1. Here, we study the critical phase: the main result is the weak limit of the size of

Introduction: Survivors of critical illness commonly experience physical, cognitive, and psychological impairments. Early rehabilitation may mitigate these impairments; however, how rehabilitation practices are perceived and implemented by healthcare professionals in intensive care unit (ICU) remains insufficiently described. This study aimed to describe healthcare professionals' perceptions of re

Ti-MXene (Ti3C2Tz) is the most common member of a larger family of 2D materials widely explored due to a variety of possible applications. MXenes are mostly synthesized using strong acids like HF and HCl or using procedures that require elevated temperatures. Here, we present a new method for Ti3C2Tz preparation with a weak acid solution, which is more beneficial for mass production with reduced e

Introduction: Therapeutic proteins are crucial in the treatment of a wide range of diseases. However, the proteins are sensitive to chemical degradation reactions, particularly deamidation and isomerization, which can compromise efficacy and safety. Formulation excipients, such as sugars and non-ionic surfactants, are commonly used to enhance stability, yet their effects on chemical degradation re

Drawing and sounding both rely on bodily movement as a basis for artistic expression. Movement provides the underlying spark that brings both visual and sonic practices to life. As part of a long-term research project titled ‘Sonic Kinesthetic Forest’, this paper reflects on a collaborative exchange between three researchers who use moving, drawing and sounding practices to deepen human relationsh

We developed a collagen microfiber-based 3D cancer tissue model that included monocytes. Using a sedimentation culture method, normal human dermal fibroblasts, endothelial cells, cancer cells, and THP-1 cells—that is, the human monocytes cell line—were cocultured under a high collagen density. THP-1 cells were differentiated into macrophages and showed M2-like polarization in the 3D tumor microenv

Invariant natural killer T 1 (iNKT1) cells are prototypic interferon γ-producing, innate-like T lymphocytes that play crucial roles in protection against pathogen infection and cancer. In the thymus, where these cells develop, iNKT cells contribute to the recruitment of antigen-presenting cells and promote T cell tolerance. Although the transcriptional programs guiding iNKT cell specification are

This scoping review aims to systematically explore the extent, nature, and gaps in the existing literature on self-care practices among adolescents and young adults aged 10–24 years living with type 1 diabetes mellitus (T1D) in Sub-Saharan Africa. The review will examine self-care knowledge, attitudes, practices, perceived barriers and facilitators, and interventions developed to support self-care

For the Inner Tracking System 3 (ITS3) upgrade, the ALICE experiment at CERN requires monolithic active pixel sensors of dimensions up to 97 mm×266 mm, occupying a large fraction of a 300 mm wafer. To manufacture such a wafer-scale device, larger than the single design reticle size, stitching is employed. The MOnolithic Stitched Sensor (MOSS) is a prototype silicon pixel sensor of 14 mm×259 mm siz

Alterations in cortical morphology have consistently been reported in obsessive-compulsive disorder (OCD). However, the microstructural properties of the cortex in OCD, including intracortical myelination, remain far less explored. The contrast between signal intensity in gray and subjacent white matter from T1-weighted magnetic resonance imaging (MRI), i.e. the gray/white matter contrast (GWC), i

IntroductionChanges in long-term survival after stroke at the population level are incompletely characterized, particularly using recent data and stratified by stroke type.Patients and MethodsThis nationwide, register-based cohort study used data from the Swedish Stroke Register (Riksstroke) and the Swedish Causes of Death Register. Adults (≥18 years) hospitalized with ischemic stroke or intracere
