This paper analyses the short-term effects of El Niño and La Niña weather shocks simultaneously, using the El Niño Southern Oscillation (ENSO) cycle and imposing assumptions on the econometric VAR model. We contribute to the climate macroeconomics literature by examining the impact of weather anomalies on commodity and food prices using monthly data. Our result for the world provides an overall in
This paper explores the relationship between geographical diversification and derivative hedging, as well as their impact on corporate value. We employed multivariate regression analysis using a sample of 211 publicly listed U.S. companies on the S&P 500 index from 2019 to 2023 to examine this relationship. Our focus is foreign exchange hedging and the interaction between hedging and firm
This thesis investigates labor exploitation within China's food delivery industry, focusing on dominant platforms such as Meituan and Eleme amid the rapid growth of the digital economy. The study is motivated by concerns about the working conditions of delivery workers, who often lack formal contracts and protections, leaving them vulnerable to exploitation, especially through the use of algor
Much of contemporary organisational life is enacted in meetings. Yet, our understanding of meetings and coworkers’ role in them remains limited and influenced by the dominant functionalist and linear perspectives on communication. Such an approach is, however, problematic as it obscures the constitutive role of coworker’s voicing in meetings and how it produces and reproduces work teams, organisat
The purpose of this study is to examine how responsibility is distributed in a bottom-up and network forms structure. Our qualitative study followed the interpretivist tradition together with an inductive approach in one organization. The empirical data was collected at “Bright Solutions” through 8 semi-structured interviews over a two week period. This paper is examined through the lens of bottom
The credit spread puzzle has long been a well-researched topic within the literature of fixed income securities, focusing on the factors contributing to credit risk to explain credit spreads. This study provides a new perspective on the subject by specifically examining corporate bonds issued by Swedish real estate companies during the years 2019 to 2023. It is investigated whether explanatory var
This study examines whether aid policies aimed at promoting national interests are more effective at generating economic growth in Least Developed Countries (LDCs) than traditional aid policies. Compared to traditional aid, these policies rely heavily on trade, as the effectiveness of foreign aid has long been under scrutiny. We assess the effectiveness of these aid policies by empirically investi
This project uses proton-proton collision data from the ALICE experiment at CERN to investigate the differences between three ways to classify events, known as event shape classifiers. The event shape classifiers that were investigated are RT , spherocity and flattenicity. The motivation behind this is the consistent use of these classifiers to select events when investigating the heavy-ion like
This research is part of a larger project exploring the use of surface modified microcarriers, specifically polystyrene and PDMS, as a chromatographic medium to enable high resolution liquid state NMR-analysis of biological samples such as blood and plasma. The purpose of the microcarriers is to bind proteins and lipids, which distorts the NMR-spectrum, hence enabling identification of metabolites
This study explores the influence of sustainable entrepreneurship education (SEE) on the ability to recognize sustainable business opportunities. Using a series of semi-structured qualitative interviews, data was collected from participants in a SEE program at Lund University. The findings reveal that SEE enhances the ability of students to identify and evaluate sustainable business opportunities
This thesis explores the contemporary cultural and political influences that both compete for and contribute to the shaping of England’s national identity. Amidst recent politicisation of nationhood and belonging, counter-narratives to prevailing regressive discourses have emerged and this thesis aims to elevate the progressive discourses that better represent modern-day, multicultural England. Th
Thesis Purpose: The purpose of this research was to explore the opinion of consumers from Asia and Europe about data privacy concerns while receiving personalised marketing campaigns. We aim to contribute in existing literature on this specific domain for future researchers and companies who want to invest in these unexplored regions. Methodology: This study has used qualitative research methodo
Given the pressing environmental crisis, marked by climate change, biodiversity loss, and deforestation, precise land cover monitoring has become crucial. In this thesis, we explore the use of privileged information to enhance land cover classification using deep neural networks. Our study specifically focuses on how to best utilise all available data, by leveraging a machine learning framework kn
Parallel to the intensified digitization of financial transactions, an ancient informal system continues to operate in the shadows, exerting a significant influence on global financial structures. Hawala, as this system is known, is recognized for its dual nature, allowing it to function as a legitimate financial system, while its informal structure, particularly its lack of governmental oversight
The QR decomposition is used to solve least squares problems, systems of equations and other important linear algebra tasks. We consider the computation of the QR decomposition for tall-skinny matrices, using the Cholesky decomposition as an intermediate step. To improve efficiency, we introduce randomised numerical linear algebra and sketching as a tool for improving computational efficiency. Num
The synthesis of small organic molecules in the pharmaceutical industry necessitates efficiency and selectivity. For obtaining selectivity in C(sp2)-H functionalization, thianthrenation has emerged as a promising method for furnishing electrophilic substrates, with thianthrene acting as a linchpin that facilitates selective functionalization through subsequent displacement reactions. This thesis u
This study delves into the role of films, particularly animated films, in shaping and reshaping international audiences’ perceptions and tourist intention of a destination.Data were collected qualitatively through semi-structured interviews with multicultural participants studying at Lund University, both before and after watching the movie.Movie attributes model (Place-Performance-Personality mod
Traditional mechanical methods for the recycling of polyethylene terephthalate (PET) fail to produce high-quality materials suitable for upcycling. Alternatives like chemical recycling face challenges due to the high energy demands, concerns, and the cost of specialized equipment. Enzymatic recycling has emerged as a promising alternative, offering a simple process under environmentally friendly c
This study explores the potential of thermophoresis as a method of translating silicon nanowires in a liquid. Thermophoresis, the movement of particles against a temperature gradient, provides a scalable method of manipulating the particles. Simulations conducted in COMSOL examined both spherical and cylindrical approximations of nanowires, focusing on their translation under varying temperature g
This paper investigates the impact of Trump’s opinion polls on U.S. Treasury yields during the 2016, 2020, and 2024 presidential elections. Focusing on both 2-year and 10-year yields, the study examines short- and long-term perspectives and compares the effects across the 2016 and 2024 elections. Using a GARCH-in-Mean model and the “Trump-Head-to-Head Momentum” (THHM) variable, we test three hypot
