The self-expression to empower oneself through fashion and dress is a fundamental aspect of personal identity and challenge of gender norms, particularly for non-binary individuals. As gender norms are social norms that may limit a person's choices of clothing and influence on how to express oneself, non-binary individuals may find it more difficult to find clothing that aligns with their pers

This study confronts the global urgency of sustainability challenges by evaluating the relationship between international trade and sustainable development, with a specific focus on Indonesia. As a nation deeply entangled with environmental issues and heavily dependent on natural resources, Indonesia's sustainability path under the influence of international trade is a subject of crucial i

The emergence of the Internet language has profoundly impacted everyday communication in China. This study examines the integration of Chinese Internet neologisms into everyday language. Through analysis of Baidu Index data and a questionnaire survey, the study explores the extent to which these neologisms have become part of Internet users’ linguistic repertoire. The findings indicate the success

I samband med den globala uppvärmningen har översvämningar, tropiska cykloner, värmeböljor och extrem torka har blivit allt vanligare världen över. De länder som har störst risk för extrema väderhändelser har minst resurser för att återhämta sig efter dem. Små önationer under utveckling och minst utvecklade länder står i synnerhet inför utmaningar när det gäller att hantera klimatkrisens effekter,The consequences of climate change and increasing disasters jeopardise the livelihoods and resilience of some of the world’s most vulnerable countries. Strengthened international efforts to mobilise and allocate additional climate and disaster resilience financing are required to address the needs of the countries that have least contributed to climate change and who currently are at the forefront

Electrification of processes has become the cornerstone of the strategy to decarbonise energy supply, especially in recent years. This study aims to define the main issues underlying the electrification of the European energy mix, especially those caused by an increasing share of intermittent energies. To this end, through a mix of qualitative and quantitative analysis and personal contributions v

Kombinera halvledarmaterial på atomnivå i nanotrådar Genom att växa nanotrådar och samtidigt studera detta med supermikroskop, kan man styra kristallväxten och utveckla nya materialkombinationer för att skapa framtidens material. Så kallade nanotrådar är i en stavform där diametern är i nm-skalan medan längden kan vara i µm-skalan. Dessa nanotrådar kan vara gjorda av kristallina material och genOne of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effe

This paper explores the potential and feasibility of a Ghanaian diaspora bond. The paper uses a mixed-method approach combining qualitative interviews with key incumbents in the diaspora finance sector with quantitative data from two surveys on diaspora bonds from the Commonwealth (2018) and Mensah (2019). Furthermore, the paper reviews the existing body of literature on diaspora bonds and other f

Det är av stor vikt att få en förståelse för vad sjuksköterskor upplever när patienten försöker begå suicid och vilket stöd de behöver för att klara arbetet. Syftet med studien var därför att beskriva sjuksköterskors upplevelser av att möta patienter med suicidalt beteende inom psykiatrisk vård. Studien genomfördes som en litteraturstudie med induktiv ansats och innefattar åtta vetenskapliga artik

Acute myeloid leukemia (AML) is characterized by an accumulation of immature blast cells, which outgrow the bone marrow and suppress normal blood formation. The condition is associated with poor survival, mainly caused by relapsed and refractory disease. Hence, new therapeutics are needed. Recently, SLC40A1 was identified as potentially important for AML cells in a pooled CRISPR interference scree

The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. Pebble accretion is considered a promising candidate to explain their fo

Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. Reducing these substantial emissions aligns with the objectives of

As society’s electricity demands increase, technical solutions and advancements are essential to meet energy needs. Solar energy is a promising source, and solar cells enable the conversion of sunlight into electricity. This study is in collaboration with Midsummer AB, a Swedish company that specializes in sustainable solar cells. The company employs a sputtering process for manufacturing these ce

Bakgrund Människor som drabbats av stroke eller traumatiska hjärnskador (TBI) får ofta balanssvårigheter som kan påverka aktivitet och delaktighet negativt. Mini-Balance Evaluation Systems Test (Mini-BESTest) är ett mätinstrument som kan användas för att utvärdera balansförmågan, men dess reliabilitet och validitet är inte helt klarlagt efter stroke och TBI. Syfte Syftet med studien var att under

Due to rising concerns about climate change, launching plant-based portion pack beverages is one opportunity to address this issue. Embracing this opportunity of value creation, requires a business model innovation. The purpose of this study is to improve the understanding of how companies in the food industry develop a new customer value proposition with business model innovation, and how this ca

With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. As living organisms, microbes must adapt to their environment, and their adaptations are reflected in the

Wood is increasingly being recognized as one of the most promising building materials on the market as a result of environmental challenges. Aside from the fact that wood is a sustainable material, it has the benefit of being high-quality, strong, flexible, and speedy to construct, which makes it a much more attractive material compared to its less sustainable counterpart. The latest computational

Försäkringsbolag behöver identifiera och hantera en stor mängd potentiellt bedrägliga försäkringsanspråk från deras kunder. Därför har försäkringsbolag en rad system för att försöka identifiera vilka anspråk som är bedrägliga och vilka som inte är det. Med den senaste utvecklingen inom maskininlärning och särskilt inom området för språkbehandling (NLP) kan dessa tekniker eventuellt användas för atMachine-Learning can sometimes see things we as humans can not. In this thesis we evaluated three different Natural Language Procces-techniques: BERT, word2vec and linguistic analysis (UDPipe), on their performance in detecting insurance fraud based on transcribed audio from phone calls (referred to as audio data) and written text (referred to as text-form data), related to insurance claims.
