Analogue atomic spectral lines from different isotopes display a small shift in energy, commonly referred as the frequency isotope shift. One of the components of the isotope shift is the field shift, which depends on the extent and the shape of the nuclear charge density distribution. In this work, we investigate how sensitive field shifts are with respect to variations in the nuclear size and sh
The purpose of this paper is to explore how competency is evaluated in the process of recruiting and selecting corporate leaders and managers. Another perspective is to understand the role of diversity in the process and how it affects the outcomes of hiring decisions. Qualitative interviews were analyzed from a single case study of eight leaders from the manufacturing sector. Empirical data regar
The turbulent market environment experienced over the last decades has attracted the broad interest of institutional and retail investors towards non-directional and absolute return investment strategies. The scope of this paper mainly concerns the investigation of whether a pairs trading strategy based on the cointegration approach generates excess returns on the Swedish equity market or fails to
The purpose of this thesis is to estimate the parameters in a stochastic volatility model in order to hedge derivatives based on underlying assets under the real probabilities as opposed to the standard method of esti- mating them under the risk neutral probabilities. We choose a common and reasonable but not to complex model of stock prices and other traded nancial assets, the Heston model, as we
Bakgrund Hållbarhet är ett koncept som har fått uppmärksamhet och som har gått från att vara ett ”modeord” till något som är integrerat i de flesta företags strategi. Författarna är intresserade av hur affärsmöjligheter kan bli utvärderade från ett hållbarhetsperspektiv och hur hållbara produkter kan skapa ett marknadsvärde. Företaget, som är verksamma inom kemi industrin, är intresserade av att k
Neurodegenerative disorders (NDDs) such as Huntington's disease (HD) and the spectrum of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are characterized by progressive loss of selectively vulnerable populations of neurons. Although often associated with motor impairments, these NDDs share several commonalities in early symptoms and signs that extend beyond motor dysfunction
The engram encoding the interval between the conditional stimulus (CS) and the unconditional stimulus (US) in eyeblink conditioning resides within a small population of cerebellar Purkinje cells. CSs activate this engram to produce a pause in the spontaneous firing rate of the cell, which times the CS-conditional blink. We developed a Bayesian algorithm that finds pause onsets and offsets in the r
he effect of viscosity on the nasal absorption and biological response to desmopressin was studied in humans. Nasal solutions of desmopressin with and without the addition of 0.25% (w/v) methylcellulose were administered by a precompression nasal spray pump to 10 volunteers. Plasma levels of desmopressin were assayed by radioimmunoassay and the biological response was measured by determination of
This work investigates the interaction between cultural norms and neighborhood characteristics, in the context of the gender gap in math. Using high-quality Swedish administrative data, I estimate the effect of mothers’ country-of-origin gender norms on the gender gap in math among second-generation immigrant siblings and exploit a refugee placement policy to obtain random variation in regional ch
In his contribution to the infuential “Architecture and the Computer”conference in 1964, Christopher Alexander summarised the reorganisation of intellectual labour that, beginning in the 19th century,became fnally concretised in the technologies of the computer. Inhis opinion, computers should be regarded as nothing else than hugearmies of clerks, stupid and without initiative, but able to follow
Echoes of Empire: Nationalism and Identity in the Late Ottoman Era (1898-1918) delves into the complex and transformative period of the late Ottoman Empire, exploring the rise of nationalistic movements that reshaped its multi-ethnic landscape. This book provides a detailed examination of the various national identities that emerged - with a special focus on Kurdish nationalism - their struggles f
This chapter acts as an introduction to the book by introducing fundamental concepts relevant to the debate. It aims to provide a structure to think about the topic. A structure that has also influenced the structure of the book. Moreover, it provides a background to the debate and summarise the most important findings of the different chapters.
Background: TDP-43 proteinopathies represent a spectrum of neurological disorders, anchored clinically on either end by amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). The ALS–FTD spectrum exhibits a diverse range of clinical presentations with overlapping phenotypes, highlighting its heterogeneity. This study was aimed to use disease progression modeling to identify nov
The food industry is vital manufacturing sector globally, with an ever-increasing reliance on digitalisation and technology-driven processes. However, this advancement introduces inherent cyberattack risks, encompassing data breaches and system disruptions, which can severely impact production and disrupt the entire food chain. Consequently, cyber threats can evoke fear and mistrust among consumer
Sovereign is who decides; and who decides is responsible. The book develops these two arguments by comparing Carl Schmitt's and Dietrich Bonhoeffer's theories of sovereignty.Carl Schmitt was an influential jurist of Nazi Germany. Dietrich Bonhoeffer was a Lutheran priest hanged for his involvement in a plot to assassinate Adolf Hitler. In many ways, the two men could not be more different. But the
The dominant road traffic particle sources are wear particles from the road and tire interface, and from vehicle brake pads. The aim of this work was to investigate the effect of road and brake wear particles on pulmonary function and biomarkers in isolated perfused rat lungs. Particles were sampled from the studded tire wear of three road pavements containing different rock materials in a road si
Firms have been increasingly relying on online user communities (OUC) to access external, distant knowledge and expertise. Previous research on OUC has largely investigated the influence of individuals' social capital on their knowledge sharing behavior. In this study, we propose a spiral view on the relationship between social capital and knowledge contribution. We suggest that there are two-way
