We consider two-dimensional travelling water waves over flows with constant vorticity and critical layers. We use global analytic bifurcation theory to show the existence of a global curve of solutions which either approaches a solitary wave or forms a critical point along the surface. In contrast to most of the previous studies, we fix the Bernoulli constant and use the wavenumber as a bifurcatio

This thesis investigates how immigrant tour guides negotiate identity and belonging through the act of guiding tourists from their country of origin in their country of residence. The study frame tours not merely as cultural encounters but as performative and affective spaces of self-representation. Focusing exclusively on the guides’ perspectives, it draws on semi-structured interviews with immig

This research characterized the barrier properties and transport mechanisms of multilayer films comprising polylactide (PLA), chitosan, and nanocelluloses extracted from agricultural by-products. The investigation employed complementary analytical techniques to evaluate water vapor and oxygen transport behavior, comparing cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) derived from cor

This thesis examines the scope of the law of State immunity from enforce-ment, with the intention of determining if the frozen assets and reserves of the Central Bank of Russia can be confiscated without implicating State immuni-ty. State immunity from enforcement has its legal basis in customary interna-tional law and is generally understood to protect State property from being subjected to pre-

LGBTQ+ tourism has attracted many tourists. As more and more tourists share their feelings and comments on social media, tourist experiences regarding this type of “niche tourism” are essential to be studied. Among all forms of LGBTQ+ tourism, pride events, one of the most popular LGBTQ+-related activities, are unique to pay attention to since they are usually held in public areas and are easy to

This thesis investigates the dynamics of systematic risk in publicly listed private equity(PLPE) firms, a hybrid asset class that combines private capital exposure with public market liquidity. Using daily data from 2015 to 2024 and a score-driven modeling framework, we show that beta is highly time-varying and firm-specific, particularly during macroeconomic shocks such as the COVID-19 crisis and

This thesis explores how young consumers navigate consumer guilt within the context of social media-narrated consumption. While social media platforms like Instagram and TikTok are known to stimulate desire and shape consumer identity, less is known about how they influence emotional responses after consumption, particularly guilt. Existing literature has largely treated social media and consumer

This thesis analyzes Socialstyrelsens (Swedish Social Services) guidelines for endometriosis healthcare, with the aim of understanding the social aspects of the medicalized field of endometriosis. Former research on transnational and Swedish endometriosis experience, studies on endometriosis guidelines and Socialstyrelsens’ guidelines for healthcare, is presented to contextualize the project. The

This thesis addresses state regulation of assisted reproductive technology in Sweden. Particularly the assessment of parental potential, which according to Swedish law is mandatory when seeking to reproduce with donor gametes through assisted reproduction. Theoretically the study enters into a critical dialogue with a reproductive justice framework, theories on reproductive racism, along with Jasb

Svenska tillståndsprocessen - hjälper eller stjälper Sveriges hållbarhetsarbete? Vindkraftsentreprenörer har länge högljutt tvekat på legitimiteten och effektiviteten av den svenska tillståndsprocessen för vindkraftsetablering. Har deras skrupler någon grund i verkligheten av dagens tillståndsprocesser eller är problematiken överdriven? Sverige har idag god tillgång till förnybar och fossilfri eWind power is crucial for achieving climate and energy targets, but prolonged permitting processes can impede its expansion. This thesis examines whether Sweden’s permitting process is an unreasonable obstacle to wind power development, with the new (2023) EU requirements under the Renewable Energy Directive III (RED III) as the benchmark. The research identifies RED III’s demands on permitting, e

The road freight sector’s significant contribution to greenhouse gas emissions necessitates emission mitigating strategies to meet climate targets, such as the Paris Agreement’s goal of 43% emission reduction. While Battery Electric Trucks (BETs) show great potential to reach these goals, their successful integration hinges on optimization and route planning. This thesis investigates the condition

The third sector encompasses organisations that are highly value-driven and oriented toward social change, often addressing needs overlooked by governmental bodies. This thesis explores the leadership experiences of women in this sector, focusing on their motivations for attaining leadership roles, self-leadership strategies used, and whether they encounter gender-based barriers throughout their l

Purpose: This thesis aims to investigate how customers’ pre-existing brand loyalty influences their perceptions of four characteristics – Perceived Usefulness (PU), Perceived Ease of Use (PEoU), Perceived Trustworthiness (PT), and Perceived Human-likeness (PH) – of AI chatbots used in customer service. In turn, we strive to examine how those perceptions affect overall customer satisfaction towards

Research question: "How do young women construct and perform aspirational identities through the Clean Girl aesthetic on digital platforms?" Purpose: The purpose of this study is to expand the understanding of how trendy aesthetics on digital platforms like TikTok shape users’ identity construction and self-performance. Theoretical perspective: Two main theoretical fields, aspirational

Purpose: The purpose of this study is to explore how consumers navigate and justify their consumption habits while striving for a more sustainable identity. The study examines the internal dilemmas that arise when sustainable values confront the realities of identity expression and social influence. Methodology: A qualitative research approach was adopted, in the form of in-depth interviews, invo

This study investigates how early-career professionals construct their professional identities within the context of graduate development programs. As organizations increasingly rely on graduate development programs to attract and develop high-potential graduates, these programs have become an important talent development strategy for cultivating future leaders. Yet, despite the growing prevalence

Society is undergoing a great transformation with regard to the climate crisis, where electrification plays a crucial role in decarbonizing. To meet the future energy demand, improving power grid utilization is essential. This thesis develops standardized methods to evaluate and identify key parameters in terms of impact and branch loading, and to determine the probability of load flow scenarios u
