This dissertation stands at the intersection of finance and machine learning to empirically delve into the intricate relation between media sentiment and market volatility, covering various aspects of this dynamic. Through three research papers, the thesis presents a detailed investigation into how media—ranging from traditional news to social media platforms—shapes market behaviors and sentiments, ...

Over the years, international elite sport has developed into an 'arms race' with the success of national elite sport systems becoming a symbol of regime superiority. During the Cold War, the Eastern and Western Blocs battled for success in various sports disciplines. The former nations were dominating in terms of medals, symbolising the force of the socialist autocratic system. However, because of ...

Collaborative approaches to destination design require conscious and reflexive stakeholder involvement in activities and decision making. Design science studies such participatory processes by observing design teams in practice. From these observations, scientists have identified design strategies and processes that design teams use to support their work in identifying problems and developing ...

This study aimed to conduct a systematic review and meta-analysis evaluating the inclusion of β-glucan in aquaculture animal diets and its impact on their health outcomes. Relevant studies were identified from Scopus and Web of Science databases. A total of 82 primary studies published between 1996 and 2024 were reviewed, of which 70 were included in the meta-analysis. The results revealed that ...

<ol> <li>Predator–prey interactions in time and space determine stock productivity, making them an important consideration when managing marine resources, rebuilding stocks or considering reopening a fishery.</li><p> <li> We analysed fine-scale diet data from surveys conducted in 2009–2010 and 2018–2019 in three fjords in northern Norway with geostatistical models investigating how predation varied ...

Research has long aimed to identify the effects of international sporting success or event hostship on nations. Overall findings suggest that tangible benefits are marginal at best. Still, some studies find that sport may have significant intangible effects, such as bolstering (short-term) feelings of national pride or happiness. Following this strand of research, the present paper asks whether ...

Across marine ecosystems, species are redistributing as a response to increased sea temperatures. In the Arctic, rapid warming causes poleward shifts of boreal species. Which species are redistributing and the drivers of their movements can be related to their life history traits. Here, we aimed to characterize and analyze the spatio-temporal changes in the life history strategy (LHS) composition ...

Conical pots are commonly used fishing gear for capturing snow crab (Chionoecetes opilio). In these fisheries, optimal snow crab size selection is important for reducing unintended mortality of undersized individuals aiming at conserving fisheries resources and reducing sorting time onboard fishing vessels. Size selection in snow crab pot fisheries commonly takes place through pot netting meshes ...
