This thesis investigates whether integrating technical market data with fundamental accounting variables improves the out-of-sample predictability of stock returns in the highly liquid S&P 100 universe. Using an expanding window approach from 2010 to 2024, the study compares the performance of regularized linear (Ridge Regression) and non-linear (Histogram Gradient Boosting) estimators against
The aim of this research is to study three particle correlations in pseudo-rapidity for the $\Lambda^0$,$\Xi^0$, and $\Omega^-$ hyperons with a focus on their baryon and strangeness quantum numbers. The two primary questions asked are, into which particles are these quantum numbers typically conserved, and what are their correlations in momentum space. The research investigates these problems by e
This thesis project explores the significance of public spaces in shaping society, culture, and individual identity, emphasizing their role in promoting democratic values and self-realization. Public spaces, such as squares and marketplaces, serve as platforms for social interaction, economic activity, and cultural continuity. The design of these spaces reflects societal values and historical cont
There is a need to closer characterise the molecular changes associated with progression from low to high mortality stage cutaneous T cell lymphoma. This has been challenging since there is high inter-patient heterogeneity in the genetics and transcriptomics of the malignant T cell populations. Modern technology has enabled single-cell resolution as well as spatially guided cell selection for whol
Purpose of study: As both innovations and brand loyalty are becoming ever more important for companies today, it is of importance to understand how an organisation can handle the relationship between the explorative and exploitative units when working with these two constructs. The ultimate aim is to understand how service organisations can be managed in order to enhance brand loyalty through serv
Positive aspects of fathers’ involvement in parenting are broadly recognized, but challenges faced by fathers are often neglected and postpartum depression (PPD) is still mainly considered as a problem of mothers. Yet, new evidence suggests a similar prevalence of about 10 % in fathers and mothers. The present study investigated paternal PPD, its character and its links to attachment styles, paren
The communicating home concept has been defined by identifying the dominating communication technologies to/from and in the homes, the most important customer behavior and user needs, the dominating products and the dominating actors of the industry. The evaluation of the communicating home industry has been performed with a five forces framework analysis and theories regarding value migration and
Problem: Since business process management (BPM) is a very spacious concept, it is influenced from many other concepts, standards and methods that determine its constancy. Companies are asked to restructure their organisation in order to meet internal and external customer demands. The term quality comes to the fore. Organisations such as ISO and the EFQM try to certify or assess companies in term
This paper provides an answer to the requests that has been made for witness confrontations to become an accurate and reliable tool in the court. This was achieved by the development and testing of the Guilty Face Test (GFT). Facial stimuli was used in a Target Present lineup were the enhanced elicitation of the Even-Related Potential component P300 confirmed recognition of the culprit. The partic
The purpose with this essay is to investigate if there are conditions for freedom of religion in Sudan after the Comprehensive Peace Agreement of 2005. My methodology is to investigate the question of religions liberty in Sudan on the basis of three social levels: state level, religious actors and individual- level. I will use Cole Durham’s comparative Model for analyzing religions liberty and app
This CMES Regional Outlook by Pinar Dinc focuses on the recent political developments in Turkey.
Due to the large amount of accidents negatively affecting the wellbeing of the survivors and their families, a substantial amount of research is conducted to determine the causes of road accidents. This type of data come in the form of non-negative integers and may be modelled using the Poisson regression model. Unfortunately, the commonly used maximum likelihood estimator is unstable when the exp
In recent years, a growing interest in sustainable tourism and outdoor recreation has emerged in Sweden and globally. While a positive development for many reasons, it coincides with other shifting patterns in recreational nature use, influenced by climate change, social media, and experimental interventions in natural areas. These developments bring opportunities to broaden participation, but als
Atrial fibrillation and heart failure have both been suggested to increase stroke and dementia risk. However, in observational studies, reversed causation and unmeasured confounding may occur. To mitigate these issues, this study aims to investigate if higher genetic risk for atrial fibrillation and heart failure increases dementia and stroke risk. Data were obtained from the population-based Goth
Debate over the future of international science takes place in light of two trends that are frequently interpreted as standing in tension with each other. The longer-term pattern shows that science is increasingly an international endeavour, as collaboration across borders has grown. A more recent apparent re-nationalisation of science, however, raises questions over the march of international sci
The purpose of this work is to identify and analyze the key important barriers to uptake the compressed biogas (CBG) plants in India for enhancing their role as a sustainable energy source. Initially, the barriers are identified from the past academic literature using literature review process and are then validated through the fuzzy Delphi method with expert opinions. The finalized barriers were
The legal opacity of AI technologies has long posed challenges in addressing algorithmic harms, as secrecy enables companies to retain competitive advantages while limiting public scrutiny. In response, ideas such as qualified transparency have been proposed to provide AI accountability within the confidentiality constraints. With the introduction of the EU AI Act, the foundations for human-centri
A crystallogenesis study of human transthyretin using the counter-diffusion method is described as an alternative to conventional convective vapour diffusion and batch approaches for protein crystallization. The X-ray diffraction results show systematic trends that exhibit unique patterns of crystallization and high crystal quality as well as a remarkable degree of coherence within extended crysta
