This paper examines the effects of public and bank debt financing on firm performance in emerging markets. Using data on 742 publicly traded firms from the BRIC countries, it is documented that bank debt may have a positive effect on operating performance of a firm. This effect is more pronounced for financially distressed firms and during the crisis period. It is also found that bank debt has a U

Med sin ökade tillgänglighet på den kommersiella marknaden har eye-tracking blivit ett allmänt tillgängligt system för att analysera ögonrörelser. Detta har öppnat upp för nya möjligheter för utvärdering av usability inom humancomputer interaction, som tidigare har varit dyrt, tidskrävande och ofta utfört baserat på dåligt dokumenterade standarder och mål. Tidigare forskning har visat att eye-tracWith its increased availability on the commercial market, eye-tracking has become a widely accessible system for analysing eye-movements. This has opened up new possibilities in evaluation of usability in human-computer interaction, which has had a history of being expensive, time-consuming and often performed based on poorly documented standards and objectives. Previous research has indicated the

The growing need for green investments has contributed to the increased issuance of green bonds. This research investigates if green bonds are priced differently from conventional bonds by measuring yield spread discrepancies. To estimate the potential yield premium, we perform a matching method and a fixed effect generalized least squares estimator from October 2016 to December 2020. We observe t

In this work, lactoferrin was studied as a function of pH, starting at a low pH of 5.5 with 5 mM salt, in terms of interactions and dynamics with small angle X-ray scattering (SAXS), static and dynamic light scattering (SLS and DLS). Under these conditions lactoferrin was expected and found to have a strong electrostatic repulsion and behaved similar to an isotropic colloid. The glass transition w

Modern society is characterized by rapid population growth and urbanization. The urban population is exposed to many risks connected to the urban way of living such as the effects of climate change, loss of biodiversity and health risks. Sustainable urban planning where ecosystem services and nature-based solutions are included can mitigate these risks. The purpose of this study is to investigate

User-centered design and usability engineering are two concepts that both roughly date back to the 1990s, and both of which have had a large impact on the practices of software-engineering and the field of software-design. How much effort is required to take these concepts and apply them, without much prior experience, to today's interconnected and geographically distributed working environmen

With the increasing use of nanomaterials in industrial production, the concept of Nanosafety has acquired importance for human and environmental protection. A complete evaluation on the potential risks of a determined nanomaterial cannot prescind from the molecular mechanism of interaction between nanomaterials and biomolecules. In this project, the interaction between a nanomaterial used in sola

This study investigated the relationship between perception of transformational leadership and burnout experience and determined the mediation effect of organizational factors on this specific relationship within a Swedish construction company. Further, differences between blue- and white-collar workers in the perception of transformational leadership and burnout experiences were examined. It was

National image as one important source of soft power has been paid close attention in China. This thesis examines China’s new national image shaping in the framework of ambitious Belt and Road Initiative (BRI), in the same time, how other countries like Pakistan and India respond to China’s self-image are discussed. By using Fairclough and Foucault’s critical discourse analysis, the thesis argues

The triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. The enzyme attracts interest in industrial applications of the catalytic behavior it possesses, such as in food and pharmaceutical industries. Thus, understanding the interface which is controlling

Denna uppsats strävar efter att undersöka det budskap som en vald läsebok, Nya Pojken och Tigern av Lars Westman (2002) förmedlar. Målet är att studera och identifiera de diskursiva praktiker som i boken konstruerar kategorierna kvinna och man. Teori delen förklarar med stöd i Judith Butlers och Julia Kristevas teorier att genus är en fortgående process som måste iscensättas gång på gång för att h

We construct and analyze Dirichlet-Neumann iterations for the 1D Poisson equation. Specifically, we wish to gain insight into how the convergence depends on material coefficients when solving coupled linear heat equations on three non-overlapping domains. We first consider the two-domain case and then extend the method to three domains. A finite element method is used to discretize the Laplacian.

There is a common notion that economic freedom has a positive effect on economic development. However, despite formal institutions considered beneficial for economic freedom being increasingly recognised there persists large differences in economic development across the globe. A possible explanation can be found within the framework of informal institutions. Economic freedom being a transmission

The problem studied in this thesis is the impact of the principle of mutual trust on the possibility of EU nationals to claim asylum and avoiding extradition for political offences within the EU. The principle of mutual trust presumes that human rights are not violated in any EU Member State. The difficulty arises if and when human rights are actually violated. It is not clear to what extent funda

Due to high usage of fossil fuels the emissions of greenhouse gases has increased to dangerous levels during the last century. Something is needed to be done soon in order to reduce emissions and stabilize the climate. The transportation sector stands for a large part of these emissions and one way to reduce these could be to instead use electric vehicles. Unfortunately, today batteries limit the

In 2019 it was estimated that 50 million tonnes of e-waste was produced of which only 20% was officially recycled which has made the e-waste problem one of the most pressing environmental issues. As the current approaches to deal with the accelerating e-waste issue seemingly is falling short, the importance of utilizing alternative measures can no longer go unrecognized. Cloud computing has the ca
