This thesis uses real data from the Bank of International Settlements to create financial networks for the interbank market using five different methods for network reconstruction. The goal is to analyze how defaults propagate to assess the importance of banks and to examine how the network’s structure affects the system’s vulnerability. By applying network theory, communicability theory, and the

Heating, ventilation, and air-conditioning (HVAC) systems are ubiquitous and are one of the major components responsible for energy consumption in a typical building system. In light of the imminent energy crisis, there is an increasing demand to revisit the building systems and save as much energy as possible. In this regard, the scope of the thesis is to explore opportunities for data-driven opt

This study aimed to examine how healthcare workers, who have taken part in internal reflection meetings, and counselors, who lead the meetings, describe their experience, their understanding of the purpose of these meetings, and what this means for the healthcare workers' motivation to participate in the internal reflection meetings. The method used was a case study with semi-structured interv

Climate change and biodiversity loss present critical challenges for humanity, yet biodiversity often remains overlooked in corporate sustainability strategies. This study, conducted within Schneider Electric’s environ- mental team, aims to address this gap by comparing the carbon intensity and biodiversity impacts of new production processes for aluminum and steel against conventional methods. Ut

The present study investigates the influence of psychological safety and team trust on work motivation on a small scale among Information Technology (IT) professionals in Sweden and Denmark. Data was collected from 57 participants using the survey method and the scales used were Workplace Trust Survey (WTS), Motivation at Work Scale (MAWS) and Psychological Safety Scale. The results showed a signi

The thesis focuses on the design of a laboratory setup for a 100 kW fuel cell system, intended for heavy-duty vehicle applications. The increasing interest in Proton Exchange Membrane (PEM) fuel cells as a viable alternative for long-haul transport stems from the limitations of battery-electric vehicles, particularly due to the weight and energy density constraints of current battery technologies.

Magnetic resonance imaging (MRI) is a medical imaging technique used to generate 3D cross-sections of body parts for medical diagnosis and monitoring. MRI scanners have a resolution that depends on the strength of their magnetic field, measured in Teslas (T). Most clinical scanners have a resolution of 1.5T and 3T resolution is used in wealthy hospitals and for research. A few research centers als

Esta investigación analiza la feria agroecológica UNIMINUTO, un ejemplo destacado de economía solidaria y de consumo sostenible en Bogotá, Colombia. Al utilizar la teoría de las prácticas sociales y entrevistas semi-estructuradas con 10 consumidores frecuentes, este estudio identifica las principales motivaciones de los consumidores para asistir a este espacio, que incluyen el apoyo a los productoThis research examines the UNIMINUTO agroecological fair, a prominent example of solidarity economy and sustainable consumption in Bogotá, Colombia. Employing a social practice theory lens and semi-structured interviews with ten frequent attendees, this study identifies key consumer motivations, including support for local producers, product quality, health benefits, knowledge acquisition, and the

With the acceleration of climate change and biodiversity loss in recent years, the neoliberal economic response to environmental challenges has been to integrate nature into market mechanisms, hoping to account for ecological degradation while funding nature conservation and restoration. This study critically examines the resulting financialisation of conservation, focussing on Scotland in particu

Peru grapples with severe water insecurity due to climate change and ecosystem degradation. In response, the government implemented the Ecosystem Services Compensation Mechanism for Water Security (MERESE), employing Payment for Ecosystem Services to incentivize nature-based solutions. Central to MERESE are Good Governance Platforms, multi-stakeholder bodies overseeing implementation and ensuring

This thesis explores Danish social workers' sensitivity to the risk of committing microaggressions towards nonbinary clients. The theoretical framework primarily relies on microaggression theory. As a point of departure, the author developed a Microaggression Scale for Nonbinary Clients, which includes eight microaggressions that nonbinary clients might experience from social workers. The empi

Continued digitization has seen the banking sector which is positioned as a national critical infrastructure face an ever-growing number of cyber-threats. This, has necessitated the need for proactive measures for detection and prevention, owing to an expanded threat landscape. This thesis proposes an approach centered on leveraging data analysis and Machine Learning (ML) to analyze and predict th

In central Budapest, when the city of Pest was developing, urban policy led to small plots built on all four sides mak- ing up the larger neighborhood block structures. Each small lot was centered around its even smaller courtyard, lead- ing to a myriad of small open spaces with little sunlight or activity. Many of these plots today have fallen into disrepair, becoming parking lots or unused p

This master thesis explores the neural encoding of speech features for hearing aid users. The study utilizes electroencephalography (EEG) and audio data from an experiment that stimulates a Cocktail Party scenario. This is a complex auditory scene, especially difficult for individuals with hearing impairments. The primary objective of the study is to investigate how different acoustic and linguist

In this project, I investigate the combination of Natural Language Processing (NLP) with Item Response Theory (IRT) to advance the assessment and scoring of open response items. Traditional psychometric assessments are grounded in well-defined quality standards, yet assessments based on natural language have missed meeting these standards. To address this gap, I integrate NLP processed open respon

Solen skiner, det är tidigt på morgonen och det känns redan varmt i staden. En sådan dag är det många som söker svalkan, men vart ska de gå i städerna? Stadsmiljön domineras ofta av bebyggelse, gator och andra hårdgjorda ytor som kan upplevas väldigt varma. Många söker sig till områden i städer där de kan svalka sig och undkomma värmen, vilket blir allt viktigare för invånare i urbana områden och Recent years of reoccurring heatwaves in urban areas have led to an awareness of the negative effect heat can have on people and ecosystems. Trees play an important role in cooling urban areas but need to maintain their vitality to do so. Therefore, this paper aims to investigate the resilience of the tree community in Malmö from the perspective of an increased mean annual temperature (MAT). In th

With increasing country-level gender equality, country-level gender differences in personality are found to increase. This is known as the Gender-Equality-Personality-Paradox (GEPP). Possibly, the GEPP is a methodological artefact. So far, the personality trait scoring method has not been investigated as a potential source of the GEPP. Three kinds of scores were investigated in the present study:

A lack of full scalar measurement invariance (MI) across groups of test takers is widely assumed to render sum scores incomparable between groups. Computing factor scores from partial-scalar-MI models has been proposed as a remedy. To what extent this scoring method affects personality assessment in diagnostic contexts has yet not been investigated. The present master thesis explored this question
