Audio Description (AD) is developing fast, becoming the norm for big streaming platforms. However, the research field remains largely underexplored. When comparing AD practices between countries, studies seem to focus on guidelines rather than how these are used, or not, by audio describers. Additionally, not enough emphasis is placed on cross-varietal differences of English AD, and in cases when

Bakgrund: Forskning visar att ett extrema inomhustemperaturer påverkar bland annat människors prestationsförmåga och förmågan att koncentrera sig. Dessutom kan ett dåligt inomhusklimat leda till hälsobesvär hos brukarna. Det är således viktigt att säkerställa att byggnader har ett bra inomhusklimat. Medeltemperaturen på jorden ökar, vilket leder också till att inomhustemperaturen ökar. Därför är Research shows that the indoor environment can have a negative impact on the users’ performance and concentration. An extreme indoor environment might lead to health problems for the users. It is therefore important to ensure that buildings have a good indoor environment. The aim of this thesis is to compare physical measurements with computer simulations regarding indoor environmental parameters.

This study examines the long-term abnormal returns of stocks following Initial Public Offerings (IPOs) and Seasoned Equity Offerings (SEOs) on the Swedish and American markets from January 2000 to March 2021. Additionally, it examines the differences between Swedish and American companies and investigates factors influencing these disparities, focusing on the importance of market capitalization at

I en tid av växande misstro till institutionella sanningsauktoriteter har alternativa verkligheter fått starkare fäste i form av konspirationsteorier. Dessa har överlappat med rörelser som till synes inte verkar ha något gemensamt med dem, och genom att undersöka dessa oväntade fall kan vi möjligtvis skapa förståelse för de fundamentala aspekterna av hur människor interagerar med konspirationsteor

Denna uppsats har med syfte att belysa några av de utmaningar som Gasellföretag ställs inför vid genomförandet av IS/IT strategier under perioder av snabb tillväxt. Studien inleds med en genomgång av funnen tidigare forskning och litteratur för att definera centrala begrepp och skapa en lägesuppfattning på ämnet. Baserat på tidigare forskning och litteratur definerades tre utmaningsområden, lednin

Kombucha, a traditional fermented tea beverage, is gaining popularity for its health benefits due to its bioactive compounds, especially glucuronic acid, known for detoxifying and hepatoprotective properties. Despite its significance, factors influencing glucuronic acid levels are not well understood. This study investigated the impact of initial sugar concentrations (4%, 6%, 8%) and tea types (bl

This thesis explores the efficacy of sentiment analysis within digital marketing, examining its role and success through qualitative methodologies, including semi-structured interviews with industry professionals. As digital marketing evolves, understanding consumer sentiment becomes crucial for tailoring strategies that resonate with target audiences. Our study delves into the application of Natu

Purpose: This study investigates the impact of personified brand strategies on consumer engagement on TikTok, a popular social media platform. The research explores how global consumer brands utilise brand anthropomorphism, with a distinction among brand ambassadors, brand spokespersons, and user-generated content (UGC), to engage with consumers on TikTok. Methodology: A quantitative content anal

Per- and Poly-fluoroalkyl substances (PFAS) are persistent environmental contaminants with significant health risks due to their resistance to natural degradation and potential adverse effects on human health. This study aims to evaluate the effectiveness of 8 commercial nano-filtration (NF) and reverse osmosis (RO) membranes in treating PFAS-contaminated drinking water. The objective was to asses

The objective of this study is to explore differences between prominent and subtle product placement (PP) interaction levels on consumer cognitive, behavioral and affective outcomes within virtual reality (VR) gaming context. Leveraging a quantitative approach, the study employs a between group experimental design to investigate the influence of in-game advertising (IGA) interactivity on advertise

Sustainability communication within the fashion industry remains constrained despite a growing focus on sustainability initiatives by brands. This master’s thesis investigates this constraint, often referred to as ‘green blushing’. Using qualitative research methods, this study examines the phenomenon through a case study of the Swedish fashion brand Kappahl. The findings reveal various factors co

Bakgrund: För att nå samhällets satta klimatmål behöver energiförbrukningen sänkas. Målet genererar ett behov att utforska nya energieffektivare ventilationslösningar. Ett alternativ är att använda markförlagd ventilation som är en mer etablerad teknik i varmare klimat och nyttan med ett sådant system i svenskt klimat behöver därför undersökas. Systemets fördelar och problematik behöver utredas saOur society needs to lower emissions and energy consumption to reach the global climate goals. One way to regulate the energy consumption in buildings is by improving HVAC installations, which makes it relevant to find new ventilation solutions with a low climate footprint. A solution frequently used in hotter climates but relatively new in Sweden is EAHE-systems (Earth-Air Heat exchangers). This

Denna studie undersöker övergången till en hållbar framtid genom att fokusera på den framväxande batteriindustrin i Sverige, med särskild fokus på Northvolt och deras etablering i Skellefteå. Målet med studien är att förstå de hinder och risker som upplevs av olika aktörer inom både den offentliga och privata sektorn, och hur dessa hanteras. Sverige har satt ett ambitiöst mål att nå nettonollutsläThis paper explores how barriers and risks are perceived by different actors involved in Northvolt's establishment in Skellefteå, Sweden, through the Multi-Level Perspective (MLP) and risk perspective. The study employs a qualitative research design and utilizes document analysis and semi-structured interviews to collect data. The findings contribute to the existing risk framework by introduci

This thesis presents an exposition of some parts of the paper: Quotients of triangulated categories and equivalences of Buchweitz, Orlov and Amiot– Guo–Keller, by Iyama and Yang. Our contribution is to present the results and applications in a way that does not require too much knowledge or familiarity with the area and to include more detail than what is usually done. The Verdier quotient is a co

Klimatförändringarna är ett faktum i världen, och för att bekämpa dem behöver vi ställa om stora delar av sättet vi lever och hur världen fungerar idag. En betydande del av våra utsläpp kommer från den höga produktion och konsumtion av produkter som ofta kräver en förpackning. Denna studie görs för att få en bättre bild av hur sex utvalda förpackningar inom dryckesindustrin kan utvärderas och klarThis study aims to investigate the ecological sustainability of different beverage packaging and compare this to consumers’ perception of the most environmentally friendly packaging type. A literature analysis was made to understand the advantages and disadvantages of different packaging as well as consumer behavior from other surveys in other studies. Lastly this study conducted and preformed its
