Conductance was calculated for trapezoidal nanowires with different forms and strengths of imperfection using kwant, a quantum transport software package that uses a tight-binding model. In this thesis it is found that increasing magnitudes of different imperfections such as surface charge and roughness roughen conductance steps, introduce resonances, and lower conductance overall with different c

Abstract Recent financial crises have demonstrated the importance of accurately measuring financial risks in order to be able to employ mitigating risk policies. This essay investigates the question whether a GARCH model augmented by an autoregressive conditional jump intensity component can improve value-at-risk forecasts in comparison to common GARCH models. Therefore, the VaR forecasting perfor

I provide evidence on the impact of pre-primary school expansion on maternal labour supply in the context of South Africa. I draw on administrative data from the South African National Census in 2001 and 2011, and a Community Survey in 2007, to extract household information. My identification strategy exploits the staggered timing and intensity in the expansion of pre-primary school facilities acr

The Magoye River is located in the Southern Province of Zambia. This is the most drought prone region in Zambia and a lot of water bodies dry up during the dry seasons, including the Magoye River. Small scale livestock farming is widespread in the area and low water availability during dry seasons forces local farmers to push their cattle long distances for drinking water and grazing during dry se

Regionalism, that has been always with us in different forms throughout the history and emerged as an alternative theory after the end of Cold War, enables us to explain new world order. Since the end of WWII, there are two types of regionalism explaining the dynamics of regional formations. The one that came into question from the end of WWII till end of Cold War is names as ‘old’ regionalism and

The thesis is concerning the lack of emphasis of human rights in the works and treaties of World Intellectual Property Organization. So, it looked at finding a human rights framework for World Intellectual Property Organization, which would provide greater accessibility and participation by the society. In order to frame it, the impacts of intellectual property on human rights were analyzed. The i

The corporate governance mechanism should be evaluated by both region and company levels, since legislation setting and regulatory enforcement are equally critical. It is found that Hong Kong outperforms than Mainland China at both levels, hereby more converge towards OECD Principles. There are root causes contributing to the differences and similarities of corporate governance in the regions, whi

The main purpose of this thesis is to study the impact of a number of independent variables on the cross-section of expected returns on NYSE, ALTERNEXT (formed AMEX) and NASDAQ stocks between 1990 and 2008 in the American market. The analysis is based on methods presented in a number of scientific articles, which will be dealt with below. This study starts with the formation of portfolios by pre-r

In our study we intend to investigate if there is a specific acquisition component, in line with Grinstein and Hribar’s study, in the bonus for CEOs in companies based in Sweden. The acquisition component will be studied in an international as well as in a domestic context, i.e. acquisitions of foreign and domestic companies. Using cross-sectional regression analysis, estimated with OLS, with Bonu

Abstract Saltmarshes are saline wetlands on intertidal shores and their anoxic sediments function as sinks for metals and other pollutants. Saltmarshes are listed as an endangered ecological community in Australia as a result of declines across their range, due to a number of factors including habitat destruction and pollutants. However, while saltmarshes have a high level of legislative protect

This paper characterizes the impact of the adoption of the euro on Swedish export pattern. Present papers present a new method in order to analyze trade patterns by empirically analyze the effects on trade by estimating the changes via the trade margins. In this paper I also use this method in order to analyze if the export of Swedish products has generated new trade in new goods or increased trad

This thesis investigates credit risk management in Nordic commercial banks and its effect on profitability. Two determinants of credit risk are chosen according to relevant literature, namely loan loss provision ratio and capital adequacy ratio. Thirteen banks in total are then investigated across the 16 year time frame from 2000-2015. The results seek to address two essential questions. Firstly,

In this study, we analyze the abnormal returns of Chinese acquirer's shareholders around the day of the acquisition announcement to check the impact of the cross-border acquisition by using event study method and difference-in-difference model. A total sample of 81 cross-border acquisition deals is used, and the results of two methods are consistent, we find that the occurrence of cross-border

This research contributes to the ongoing debate on whether women's education and fertility are inversely related. It is seen that during the premodern era, the number of children born per woman was high and the only thing that kept population growth low was the high death rate. However, the modernization of societies resulted in a reduction in the number of births per woman. Hence the causes o

The aim of this paper is to cover a gap identified in the literature by finding empirical evidence explaining the relationship between the target firm’s ESG score and ESG Gap and the abnormal returns registered by the acquirer. The paper uses a cross-sectional dataset based on an international sample of 171 merger and acquisition transactions, occurred between 2002 and 2020. The even-study metho

Bakgrund: Det finns en brist på studier som belyser omvårdnad inom ambulanssjukvården. Fokus ligger på den akuta medicinska behandlingen och omvårdnadsåtgärder prioriteras inte i ett akut skede. För att kunna utveckla ambulanssjukvård är det viktigt att inte bortse från omvårdnadsbehov i det akuta skedet. Syfte: Syftet med föreliggande studie var att belysa ambulanssjuksköterskors perspektiv på om
