An extensive public health literature has linked the low take-up of healthcare services in developing countries with measures of accessibility such as distance, duration and cost of travel to the nearest health facility. However, causality has been difficult to prove, given the endogeneity of factors influencing access, such as the availability and quality of roads and transportation. Using a natu

This study examines how descriptive, predictive, and prescriptive analytics are applied in decision-making during stable operations and disruptive events, focusing on the Swedish food retail sector during the Covid-19 pandemic. Using a qualitative case study approach with semi-structured interviews and pattern-matching analysis, the research reveals key differences in analytics usage. During stabl

The aim of this Master Thesis was to develop an anti-slip controller for a small single person electric vehicle to prevent slipping during acceleration. Due to limited space on the vehicle it is not possible to fit sensors for measuring the vehicle’s speed, and thus the traditional way of calculating slip by comparing wheel and vehicle speed is not possible. Another difficulty was the fact that th

Populationen av västerländska akademiker och studenter visar tecken på ideologisk bias i termer av sin sammansättning och villighet att självcensurera. Denna studie undersökte en svensk population av studenter (N = 89), huvudsakligen från samhällsvetenskapliga områden, i termer av ideologi (Moral Foundations; MFQ-20 och Social Dominance Orientation; S-SDO). Studien undersökte också relationen mellThe population of western scholars and students shows signs of ideological bias in terms of its composition and willingness to self-censor. This study surveyed a Swedish student population (N =89) of predominantly social scientists on ideology (Moral Foundations; MFQ-20 and Social Dominance Orientation; S-SDO). The study also explored the relation between self-censorship (SC), age, gender and univ

Bakgrund: Den kulturella mångfalden i Sverige har ökat under de senaste decennierna, främst som en konsekvens av migration. Denna utveckling påverkar hälso- och sjukvården, som möter en alltmer varierad befolkning. Socioekonomiska och kulturella skillnader har en inverkan på tillgången till vård och på vårdens kvalitet. Det anses nödvändigt att vården anpassas för att kunna bemöta de skiftande beh

That an additional tariff of 25 percent could go unnoticed in global trade might seem unlikely, but the findings of this study suggest exactly that. Against the backdrop of escalating trade tensions between the EU and the US, this study examines both the immediate and short-term effects of the EU's temporary additional tariff of 25 percent on the import of exercise equipment. By focusing on th

Täppt näsa, halsont och nysningar är symtom du säkert har upplevt vid en förkylning. Förkylningar är vanligast under våren och hösten och orsakas oftast av Rhinovirus. Även om en förkylning oftast är en lindrig åkomma för de flesta så kan den ha allvarliga konsekvenser för personer med nedsatt immunförsvar eller underliggande sjukdom. Förkylning sprids via direktkontakt, indirekt kontakt (såsom Airborne viral diseases have long been neglected but with the recent devastating impact of the COVID-19 pandemic serving as a catalyst for new science, additional viruses are examined. This thesis investigates the infectivity of Rhinovirus, the virus causing common cold, in differently sized bioaerosols. The experimental setup utilized a bio-aerosol nebulizing generator (BANG) to generate droplets

This paper investigates the application of a Long Short-Term Memory (LSTM) model to construct a forward-looking risk factor for asset pricing. The LSTM model's predictions are utilized to create a novel risk factor, derived from long-short portfolios, offering an innovative approach to decomposing asset returns. For comparative analysis, the Fama-French three-factor (FF3) and Carhart four-fact

Den europeiska textilindustrin står inför stora förändringar när EU:s nya förordning "Ecodesign for Sustainable Products Regulation" (ESPR) träder i kraft. En central del av regleringen är förbudet mot förstörelse av osålda konsumentprodukter, en åtgärd som syftar till att minska miljöpåverkan och öka hållbarheten inom modeindustrin. Studiens mål är att undersöka hur textilindustrin förbStatistics show that approximately 2,71 billion people have at some point shopped for clothes online (Sellers Commerce, 2022). E-commerce is becoming more and more common rather than to buy and try on clothes in a physical store which has led to many clothes being returned for various reasons (poor fit, free returns, etc.). The fast fashion industry generates significant textile waste, with unsold

Nya katalysatormaterial för vätgasproduktion I kampen mot de pågående klimatförändringarna behöver vi byta ut fossila bränslen mot hållbara alternativ. Med hjälp av avancerade mikroskop kan man studera nya partiklar som kan bli viktiga i framställningen av förnybart bränsle. Ett attraktivt alternativ på förnybart bränsle är vätgas, eftersom det enda utsläppet som bildas vid förbränningen är vattAchieving efficient production of hydrogen through the hydrogen evolution reaction is an attractive source of non-fossil fuel. However, this reaction is inefficient and therefore requires catalysts with the most commonly used one being Pt. Due to the high cost and rarity of Pt, research into alternative catalyst materials such as transition metal phosphides has been conducted in the recent years.

Economic sanctions, a key foreign policy tool in global diplomacy, present both challenges and opportunities, yet relatively underexamined in scholarly research. Unlike previous sanctions aimed at natural resources, the US-China trade war targets labour-intensive manufacturing, creating unique opportunities for investment relocation to labour-abundant countries. Vietnam’s success in attracting sub

Recent research in organo-metallic cages composites (MOCs); discrete, self-assembled coordination compounds; has highlighted their significant potential in host-guest chemistry and catalysis. New studies focus on synthesizing multifunctional MOCs by combining more than one ligand. However, due to the unpredictable nature of coordination-driven self-assembly, intricate strategies were imperative to

Denna studie undersöker hur makroekonomiska faktorer påverkar volymen av M&A-transaktioner i USA, Storbritannien och Tyskland mellan 1993 och 2023. Genom en kvantitativ analys med en vektor-autoregressiv (VAR) modell identifieras real BNP, inflation, ränta och aktieindex som betydande faktorer, vars inverkan varierar mellan länderna och över tid.

On the other hand, the multitude of pressures on the environment, are eroding environmental resilience and increasing vulnerabilities to disasters. To counteract these pressures on the humanitarian syst

Bakgrund: Hos vuxna personer med autism kan den sociala delaktigheten vara bristfällig. Många söker sig inte till vidareutbildning och har ofta svårt att skaffa eller behålla ett arbete. Detta skapar en risk att hamna i socialt utanförskap. Syfte: att undersöka vilka aktivitetsbaserade interventioner som finns och dess påverkan på aktivitetsengagemang och social delaktighet hos vuxna med autism. MBackground: Social participation is often deficient for adults with autism. Many do not seek further education and often find it difficult to get or keep a job. This creates a risk of social exclusion. Aim: to investigate which occupation-based interventions exist and their impact on occupational engagement and social participation in adults with autism. Method: A general literature study includin

This thesis uses the unsupervised deep learning method of generative diffusion models to generate images of paperboard surfaces. As the images are intended to be used as input to various simulations by food packaging company Tetra Pak, simply looking at them is not sufficient to determine their quality. For this reason, some new evaluation metrics, specific to paperboard images, are proposed and u
