The purpose of this thesis is to determine whether or not focused funds can outperform bigger and more diversified funds, both in mean return and in its relation to risk taking. The data used in this thesis consist of 67 Swedish mutual funds, one benchmark index and 129 stocks. All data is from the period 2007-2011. The fund data is retrieved from FactSet, the benchmark index from SIX-Telekurs an
Air pollution is a serious problem today, both from an environmental and from a health point of view. Especially in cities, particles smaller than 10 µm in aerodynamic diameter (PM10) can reach high concentrations. These particles are dangerous, even at low concentrations, since they are small enough to enter the lungs. In order to estimate the concentration of air pollutants, different measureme
The U.S.-China trade war, which began in 2018, remains a critical issue in global trade, with Trump’s return to office in January 2025 heightening tensions as he threatens to impose further tariffs on, and beyond, China. This thesis investigates both the direct effects of U.S. tariffs on trade between the U.S. and China and the indirect effects on Vietnam. The primary focus is to examine Vietnam&#
Trots att forskningen kring transpersoner har ökat exponentiellt de senaste decennierna så vet vi fortfarande lite om den könsbekräftande vården utanför samhällets dominerande institutioner. Utifrån gruppintervjuer och självbiografiska inslag möjliggör denna uppsats en ökad förståelse för de som utför hormonbehandlingar utanför det officiella vårdsystemet. Uppsatsen fokuserar främst på hur den sveAlthough the field of transgender studies has grown exponentially during the last decades, little is still known about gender affirmative medication outside institutionalized settings. Based on group interviews and autoethnographic accounts, this thesis sheds light on the experiences of practitioners of unprescribed hormone replacement therapy. The focus will be put on how the Swedish welfare stat
The market for cryptocurrencies has been known to be volatile with an asymmetrical return distribution where occasional extreme returns appear. In later years options have been introduced on the asset; but due to the characteristics of cryptocurrency returns, researchers have found it troublesome to value these options. Primarily, research has been advocating for advanced pricing models and sugges
Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with mark
This study analyses the influence of environmental and individual conditions on the quality and the speed of entrepreneurial re-entries in emerging economies after a business failure. We propose a conceptual framework supported by the institutional economic theory to study the influence of environmental conditions; and human and social capital to study the influence of individuals’ skills, experie
The study of students' use of representations is one of the main topics of physics education research and is guided by the overarching field of semiotics. In this paper we compare two semiotic frameworks, one coming from didactics of mathematics and one from physics education research; the theory of registers of semiotic representations and social semiotics, using the networking of theories method
We present an analysis of atmospheric transport impact on estimating CO2 fluxes using two atmospheric inversion systems (CarboScope-Regional (CSR) and Lund University Modular Inversion Algorithm (LUMIA)) over Europe in 2018. The main focus of this study is to quantify the dominant drivers of spread amid CO2 estimates derived from atmospheric tracer inversions. The Lagrangian transport models STILT
This essay posits artistic and curatorial strategies as modes of social improvisation that operate in relation to social and political imaginaries. It considers compositional mechanisms of artistic work as models of intervention that bear the potential to produce critical instances of an ephemeral de-instituting. I seek to develop further the term “destituent spaces” as a model for current curator
Space tourism is an industry with risks including health and safety, space debris, biological hazards, and sustainability concerns. However, there is limited research on the perceived risk of participation in space tourism, particularly regarding age and gender differences. An integrated research model was created and tested with four perceived risk dimensions using fuzzy-set Qualitative Comparati
We investigate the effects of three events with major importance for climate policy on energy sector stocks: the Paris Agreement, the Trump election and presidency, and the Biden election. By combining event studies with impulse-indicator saturation methods, we show that the Paris Agreement and the election of Mr. Biden benefited renewable industries, while the election of Mr. Trump had negative e
Background: Patients with bacteraemia caused by gram-positive bacteria are at risk for infective endocarditis (IE). Because IE needs long antibiotic treatment and sometimes heart valve surgery, it is very important to identify patients with IE. Objectives: In this narrative review we present and discuss how to determine which investigations to detect IE that are needed in individual patients with
The assessment of entrepreneurship education outcomes should move beyond a focus on firm creation and associated economic impact to consider a more nuanced view that pays attention to graduates and their entrepreneurial competencies. There is currently limited understanding to what extent entrepreneurial competencies developed through entrepreneurship education are applied in graduates’ subsequent
