This thesis investigates whether firm-level innovation predicts both stock returns and future profitability among Swedish listed firms, an area that remains underexplored and inconclusive despite its growing importance. Using patent-based measures of innovation, I analyze the impact through portfolio analysis and Fama–MacBeth regressions. The results show that innovation is positively associated w

The digitalisation and introduction of social media is a factor that today affects children’s lives a lot. So called “kidfluencers” are a phenomenon that is booming and that is becoming more and more frequent. The aim of this essay is to look into the impact that social media and “kidfluencers” may have on children in Sweden today. An interview study has been done, in which parents and educators

This study aims to understand how work towards equality and diversity within trade unions represents different problems that need to be overcome in order to reach gender equality and equality overall. Swedish trade unions play an important part in writing the collective agreements between workers and employers, and therefore play an important part in equality within the field and our society as a

While the original ideals of sport were rooted primarily in recreation and physical competition, they have since long been complemented, potentially even overshadowed, by elements of entertainment and commercialization. At the center of professional sports stand sports governing bodies, typically or- ganized as non-profit organizations, which are responsible for regulating their respective discipl

In 1972 Hajnal and Kertész published a paper proving that the Axiom of Choice is equivalent to the assertion that a groupoid structure can be defined on every set. This thesis aims to provide the necessary background needed for this proof. In the first part basic concepts in set theory such as the Well-Ordering Theorem are derived. This culminates in a lemma by Hartogs (1915) in which it is shown,

This thesis explores the use of revolving doors in emergency evacuations, focusing on their function, public understanding, and associated safety risks. Although revolving doors are common in many buildings, their role in evacuation strategies remains unclear and varies between facilities. Through literature review, observations, and interviews with both passers-by and individuals with experience

Research suggests maturing adolescents’ development of Internalizing Problems like Anxiety and Depression, might be due to impaired Executive Functions. However, most knowledge on the topic is non-causal, within clinical context and predominantly focused on Executive Functions assessed with performance tasks and not everyday Executive Problems assessed using questionnaires. Therefore, we cond

Legal abuse is an underrecognized form of domestic violence and coercive control in the legal system, with laws recognizing its proliferation only recently being sparsely enacted. At the same time, the conversation about coercive control as a form of domestic violence has been rising both domestically and internationally. This exploratory, qualitative study endeavors to understand if that rising c

When particles are dispersed in a microfluidic device, its resonant frequencies can be used to manipulate their positions at will. This practice, called acoustophoresis, has been shown to successfully control multiple particles simultaneously with a single vibrating actuator, which is a low-cost and contactless alternative to existing particle manipulation methods, and whose applications include i

This thesis investigates the parallels between experiences of left-handed individuals and queer individuals to explore how societal norms are constructed and maintained through prejudice. The study draws on theories such as social constructivism, labelling theory, symbolic interactionism, Foucault’s concept of power and knowledge, and the sociological concepts of stigma and norms. Through surveys

This thesis approaches the cryptoporticus of private roman architecture in the context of the rural villa and urban domus, with the explicit purpose of examining how the functions and roles of this multifaceted structure differs in these settings. In order to accomplish this goal, the thesis employs a comparative methodology where specific attributes of eleven buildings with a cryptoporticus are p

What makes a place meaningful to a community, and what happens to those meanings when the city changes? This thesis investigates architecture's role as both keeper and creator of collective memory in urban environments. Building on sociological theories, this research explores how memories are stored in the built environment, not as static entities but continuously formed, repeated, and trans

Denna uppsats undersöker hur Lean Startup-principer kan stödja snabb filtrering och tidig validering av entreprenöriella idéer i osäkra sammanhang. Även om det empiriska fokuset ligger på digital finansiell utbildning för unga yrkesverksamma, är det övergripande målet att bedöma om en strukturerad, hypotesdriven metodik kan främja välinformerat beslutsfattande i de tidiga faserna av affärsutveckliThis thesis explores how Lean Startup principles can support the rapid filtering and early validation of entrepreneurial ideas in uncertain contexts. While the empirical focus is placed on digital financial education for young professionals, the broader objective is to assess whether a structured, hypothesis-driven methodology can support informed decision-making in the early stages of venture des

Denna uppsats undersöker hur parader genomförda av nordirländska protestanter både påverkar och formas av den kulturella kontext de genomförs inom. Genom att applicera grounded theory på kvalitativ information inhämtad via intervjuer och skriftliga svar från protestantiska informanter har deras reflektioner om paradens skiftande roll inom en kollektiv protestantisk identitet analyserats, huvudsakl

This thesis examines the influence of a foreign-born background on students’ educational choices in Sweden, focusing on the selection between vocational and university preparatory programmes in upper secondary education (gymnasium). Recognising that personal experiences and social contexts shape such decisions, a qualitative methodology was adopted to explore the underlying motivations and influen

This thesis investigates the performance of two model predictive control (MPC) variants for autonomous racing, using a 1:10-scale vehicle as a testbed for reference path-tracking experiments. The platform is equipped with a single inertial navigation system (INS) sensor, providing highly accurate odometry measurements. The controllers under study are the standard gradient-based MPC and a sampling-

This thesis is a theoretical study of thinking with water in relation to feminist theory of care, solidarity and ethics. The thesis is inspired by Astrida Neimanis’ concepts of hydrofeminism (2012) and bodies of water (2017) and has these as its starting point and main theory. The thesis asks: what can we learn from water in relation to relationality, difference, responses to the climate crisis, e

This paper is an empirical study on the effect that different weather conditions have on electricity prices in Denmark between the 29th of April 2023 and the 29th of April 2025. The study analyses how daily time series data for wind speed, temperature and solar exposure impacts daily electricity prices in respective bidding areas. The findings of this paper concludes that each of the measured weat

The availability of light pulses down to the attosecond timescale has led to the development of spectroscopic methods capable of resolving the dynamics of electrons. By studying the interference of electron wave packets (EWP) on their natural timescales, greater understanding of the dynamics can be gained. An attosecond pump-probe technique has been applied previously in Lund to study attosecond
