This thesis takes Pop Mart as a representative to study how emerging Chinese brands participate in the construction of global identity through visual and emotional narratives. Under the guidance of postcolonial theory, this study analyzes how Pop Mart strikes a balance between cultural expression and global appeal by designing hybrid characters that integrate East Asian aesthetics with global visu

This study focuses on the perception of Nordic brands by Chinese consumers in the context of cross-cultural brand communication, with an emphasis on the influence of the country-of-origin (COO) effect and consumer ethnocentrism on brand attitude and purchase intention. The research adopts quantitative methods, through online questionnaire surveys. Consumers’ responses from new first-tier, first-ti

This study examines how Chinese CEOs construct culturally resonant brand personas through narrative strategies and archetypal roles across multiple digital platforms, using Lei Jun as a representative case. Grounded in a constructivist communication paradigm, the research integrates cultural branding theory, archetype theory, and narrative analysis to conceptualize branding as a process of meaning

With the rapid diffusion of short video social media, a wave of rural influencers has emerged on China’s TikTok (Douyin), using short-form content to build personal brands and engage in sociocultural expression. Anchored in practice theory (Shove et al., 2012), this study adopts the “material–competence–meaning” triadic model to examine how these rural creators strategically construct personal bra

När passagerarfartyget Marco Polo gick på grund utanför Skånes kust hösten 2023 läckte olja ut i havet. Men vad händer med livet under ytan efter ett sådant oljeutsläpp? I denna studie har blåmusslor använts som naturens egna vittnen och deras skal bär på spår av hur djur anpassar sig till en förorenad värld. När ett fartyg går på grund och släpper ut olja i havet är det inte bara stränderna som Oil spills are known to cause severe ecological damage, yet the long-term effects on benthic organ-isms are still not fully understood. This study investigates how blue mussels (Mytilus edulis trossulus) were affected by the 2023 oil spill caused by the grounding of the passenger ferry Marco Polo in the Hanö bay, southern Sweden. Here I compare mussels collected from four oil-contaminated sites wi

Semiconductor nanowires with high refractive index have waveguiding properties that can enhance the excitation and the quantum yield of a surface-bound fluorescent molecule, and guide and directionally emit its optical signal. Prior work has shown that this allows for enhanced optical biosensing in transparent sample matrices, with advanced image analysis techniques further improving sensitivity.

Flexoelectric effect, or flexoelectricity, is an electromechanical property of materials that causes them to polarize when subjected to inhomogeneous deformation. Despite its significance in nanoscale systems, flexoelectricity remains poorly quantified in semiconductor materials. This study aims to develop a computational framework for investigating flexoelectric effects in thin-film semiconductor

This thesis examines brand activism's role in promoting social change through contributing to democratic debates by analyzing Oatly’s environmental brand activist campaigns in a polarized context: the United States. Therefore, the research questions chosen for this thesis examine, firstly, how Oatly discursively constructs their environmental brand activism in the United States; secondly, whet

De kallas ”evighetskemikalier” Det började med att öka flygsäkerheten på Arlanda men har idag lett till en miljömässig påverkan. De så kallade evighetskemikalierna, PFAS, sprider sig i marken och grundvattnet vid Sveriges största flygplats. Men vad är det egentligen som sker under markytan som inte syns med blotta ögat? PFAS är kemikalier som är stabila och mycket svårnedbrytbara i naturen. Det mPFAS contamination has been identified at numerous sites worldwide, particularly at firefigh-ting training facilities. Firefighting foams, Aqueous film forming foam (AFFF), used at these facilities often contain PFAS as their active substance. The aim of this study was to examine factors that influence transport of eleven different substances of PFAS. Furthermore the study aimed to see how long ti

The growing demand for corporate transparency and sustainability has intensified the need for effective sustainability reporting, especially in industries like fashion, which face significant environmental and social challenges. This study examines how Patagonia, a leader in sustainable fashion, applies the Double Materiality (DM) framework in its social media communications, focusing on Instagram

This thesis analyzes how moral brands discursively construct legitimacy and investigates the role of morality in legitimizing brand legitimacy claims and actions. By applying legitimacy theory, the study explores how Patagonia and TOMS Shoes legitimate their moral claims and actions based on discursive legitimation analysis (DLA). Findings showed the frequent and unexpected use of authorization, s

We introduce a method to enable Hamiltonian Monte Carlo (HMC) to simulate from mixed continuous and discrete posterior distributions. In particular, we show how the "Gumbel Max Trick" and the Concrete (Gumbel-softmax) distribution can be used for constructing a continuous approximation of a categorical distribution, and how this distribution can be efficiently implemented for HMC. We also illustra

Gamma-ray bursts (GRBs) are intense, short-lived bursts of gamma-ray radiation observed up to a high redshift (z ∼ 10) due to their luminosities. Thus, they can serve as cosmological tools to probe the early Universe. However, we need a large sample of high-z GRBs, currently limited due to the difficulty in securing time at the large aperture telescopes. Thus, it is painstaking to determine quickl
