This report investigates the multi-label classification problem of expense-related documents, aiming to be classified into nine distinct types of categories. Various machine learning methods including Naive Bayes, Logistic Regression, Support Vector Machines, Linear Discriminant Ana- lysis, k-Nearest Neighbors, Decision Trees, Random Forest, Gradient Boosting, and Recurrent Neural Networks were em

This study explores the perceptions of graphic designers regarding the impact of generative artificial intelligence (GenAI) on their profession. It aims to highlight practical examples of how GenAI is integrated into the work of graphic designers. To achieve this, qualitative data was collected through semi-structured interviews with six professional graphic designers. The findings reveal that the

I studien undersöks utmaningar och förbättringsförslag relaterade till arbetsmiljö, säkerhet och kommunikation inom byggindustrin för utländska arbetstagare, med extra fokus på länderna Polen och Litauen. Fri rörlighet för arbetstagare inom EU, som fastställs av artikel 45 i EUF-fördraget, möjliggör lika tillgång till både arbetsmöjligheter och behandling oavsett nationalitet. Syftet med studien The study examines challenges and improvement suggestions related to the work environment, safety, and communication within the construction industry for foreign workers, with a particular focus on Poland and Lithuania. The free movement of workers within the EU, as established by Article 45 of the treaty on the functioning of the European Union, ensures equal access to both employment opportuniti

In the face of global challenges such as regional conflicts, climate change and economic recession, the emergence of the Covid-19 pandemic added a unique dimension to the complex landscape that governments had to navigate. Unlike other challenges, the pandemic's solution was theoretically straightforward – the only way to stop it was mass vaccination. However, the issue of vaccine hesitancy by

This thesis explores the impact of preemptive patenting strategies on technological competition in the context of the US semiconductor industry. Employing publicly available patent data from 49 US based semiconductor firms, strategic patents serving preemptive purposes are identified through self-citations to prior art. Patent-level data is analyzed to determine whether strategic patents deter fut

In various consumption decisions, from what clothes to wear to what investments to make, individuals are influenced by the choices of others. Such peer effects sometimes lead to herd behavior in the form of, e.g., fads and financial bubbles. To understand these processes, it is crucial to understand the underlying mechanisms. The novel experimental design of this paper allows for a separation of p

The primary goal of this thesis is to understand the role of cornerstone investors in the long-run performance and survival of IPO firms issued during 2014-2023 in the Swedish market. While the phenomenon of cornerstone investors is relatively new, the trend has been increasing exponentially globally. We use several dimensions of cornerstone metrics to explain the dynamics of IPO performance and s

Minimal submanifolds constitute a central area within the realm of differential geometry, due to their many applications in various branches of physics. An illustrative example is found in the behavior of soap films, which in striving to balance pressure, naturally assume surfaces characterised by zero mean curvature. In this thesis we will employ a recent result of S. Gudmundsson and T.J. Munn t

This thesis tries to convey the point of view of migrant women living in Lund in regard to their perception of safety and experiences of violence in public spaces. To frame this case, it is necessary to consider the state of politics in Europe, which in the past few decades has seen the existing right and far-right-wing parties gaining a lot of traction. With the increase of their popularity came

Based on the European commission, climate change has become a serious threat for all aspects of our lives, urgent action needs to be taken. All the industries need to monitor their contributions, among them the building industry has the highest emission (European Commission) This study aims to compare energy efficiency and global warming potential (GWP fossil) emission in two ventilation systems i

The purpose of this paper is to investigate the exposure to transition risk within the syndicated loan market under various scenarios. The target reductions, as presented in the Paris Agreement alongside notions of reducing negative impacts of climate change provide a rationale for investigating the topic. In the investigation, data consisting of 30858 (780) observations was utilized for the respe

Wheat is our most cultivated grain and has been used as human food for thousands of years, but as the population increases, so does the demand for grain. Challenges that we face today are that the amount of cultivable arable land is decreasing, that climate change is affecting crop yields, while people's concerns are growing about the use of chemical pesticides. It is therefore of great intere

Car parking is increasingly perceived as problematic for urban landscapes; parking occupies large amounts of space and is an important motivator for car use. Private housing developers are an increasingly important player in contemporary urban development. Their responsibility for the provision of parking at new developments means that these actors will have a considerable impact on urban transpor

This paper studies heterogeneity in the euro area transmission mechanism as dependent on financial development. The topic is interesting, and research on it may provide answers to questions such as how member states can reduce their inflation rate. The hypothesis is that responses of inflation and output to discretionary monetary policy are larger in member states with a higher level of financial

This master's thesis delves into the comprehensive analysis of cost-benefit aspects pertaining to fire detection systems, with a specific application to such systems at the scientific facility CERN. Fire detection systems play a critical role in ensuring the safety and security of buildings and occupants. The study aims to evaluate with a cost-benefit methodology the tipping point at which the

Trading commodities has been around for centuries, and today, most trading is done electronically on exchanges in derivatives contracts. Over time, regulatory bodies, specifically the CFTC, have sought to implement safeguards against market manipulation by participants. One such measure has been position limits on derivatives, which since January 1st, 2023, also includes so-called economically equ

This thesis assesses the complex relationship between International Economic Organisations (IEOs), taxation, and human rights, shedding light on the impacts, obligations, and assessment practices of the World Bank, International Monetary Fund (IMF) and the Organisation for Economic Co-operation and Development (OECD). In an era of globalisation, the impact of these IEOs on financial policies, incl

Genom en ökad medvetenhet hos konsumenter om deras klimatavtryck har det blivit viktigt för företag att positionera sig som hållbara. I samband med detta har begreppet ”grönmålning” etablerats inom sammanhang som exempelvis vilseledande marknadsföring, där företag försöker framställa sig som miljövänliga utan en vederhäftig grund. För att adressera innebörden av grönmålning och finna ett tillvägagWith consumers becoming more aware of their environmental footprint, it has become important for companies to position themselves as sustainable. In this context, the term "greenwashing" has been established to describe misleading marketing practices where companies try to portray themselves as environmentally friendly without a valid basis. To address the meaning of greenwashing and fin

The upcoming EU Regulation on prohibiting products made with forced labour on the Union market is forming the occasion for this Master’s Thesis. In particular, the topic of forced labour is analysed to provide a brief insight into the necessity of the Regulation. Furthermore, a variety of international and European legal instruments are compared to the new Regulation in order to identify the actua
