Purpose: The purpose of this study is to investigate how the current green bond standards influence the use of proceeds obtained from the issuance of green bonds. We also aim to explore the limitations of the standards and how the standards can be further improved to promote the development of the green bond market. Methodology: A qualitative research approach was used, consisting of a literature
The 21st century has been marked by repeated financial crises that have challenged the effectiveness of traditional portfolio management strategies. Events such as the 2008 financial crisis, the Eurozone debt crisis, and the COVID-19 pandemic have exposed the vulnerabilities of conventional models, such as the widely used Markowitz (1952) mean-variance framework. Since this model balances risk and
The theory of the Investment Development Path (IDP) by John H. Dunning suggests that as a country develops, its composition of inward and outward foreign direct investment change both regarding to quantity and type of investment. The theory consists of 5 stages a country passes as its OLI-advantages develop. In this paper we have applied the theory of the IDP on the case of Brazil in order to eval
”Cross-boundary Antifashion - Subversive fashion and subcultural styleicons as a source of inspiration within contemporary mainstream fashion” is a bachelor thesis themed, as the name suggests, on how subversive fashion is diffused to a mainstream context. The main purpose of this thesis is to contribute to the current discourse and earlier studies of subcultural fashion by filling a gap of knowle
The aim of this thesis is to find an efficient simulation method of the Heston model of stochastic volatility to price path dependent derivatives. The volatility process in this model has an exact transition density defined as a scaled non central chi2 density. By implementing classic approaches of approximating the non central chi2 distribution, and modifying Andersen's Quadratic Exponential
Popular Abstract in Swedish Den här avhandlingen behandlar unionens statsstödskontroll och dess tillämpning på statliga stöd till banker. Den huvudsakliga problemställningen i avhandlingen berör vilka villkor som måste vara uppfyllda för att bankstöd ska kunna förklaras förenliga med den gemensamma markanden, enligt unionens statsstödskontroll i artikel 107 3 FEUF. Avhandlingen behandlar alla bankThis thesis examines the state aid rules of the European Union and the application of these rules on banks. The primary problem that is addressed is what conditions should be fulfilled in order for state aid to banks to be declared compatible with the Common Market according to article 107 3 FEUF. The thesis addresses all kinds of state aid to banks and these have been divided into the following g
This study investigates the impacts of nuclear and renewable energy consumption on Sweden’s environmental quality from 1965 to 2022. The study employs an Autoregressive Distributed Lag (ARDL) approach combined with a Bounds test to examine the validity of the Environmental Kuznets Curve (EKC) and Load Capacity Curve (LCC) hypotheses simultaneously. This is conducted within the context of Sweden

Tadpoles from two types of ponds, temporary and permanent, were raised in a common garden experiment. There was no clear effect of pond type on development rate (time for metamorphosis). From each sibship, one group was raised under a constant water regime (deep tanks) and one was subject to simulated pond drying (shallow tanks). The tadpoles exhibited a plastic response to pond drying: they metam
Popular Abstract in Swedish Kryptering kan användas när man vill hålla något viktigt meddelande hemligt, till exempel vid en bankbetalning på Internet. Men hur vet man att krypteringsalgoritmen (sättet att kryptera på) är tillräckligt säker? Hur vet man att ingen kan läsa vårt meddelande eller ändra i det så att, till exempel, en överföring av pengar från ett konto till ett annat går till någon heThe aim of this dissertation is to show some cryptanalytical results on a selection of stream ciphers. We have grouped theory and results into three main parts. The first part focuses on the FCSR-based constructions X-FCSR and F-FCSR-H v3. For the X-FCSR family of stream ciphers we perform a severe state recovery attack. This attack works for both X-FCSR-128 and X-FCSR-256. We then develop a gen
Popular Abstract in Swedish Denna avhandling fokuserar förändringar inom den arbetsmarknadspolitik som erbjuds arbetslösa socialbidragstagare mellan 1989 och 2002 i Sverige. Denna förändring beskrivs som en process där kommunerna tar allt mer ansvar för arbetsmarknadspolitiken. Denna grupp arbetslösa kategoriseras som en speciellt problematisk grupp och hänvisas till kommunerna. Detta sker utan tyThis dissertation focuses on changes in labour market policies that were provided for unemployed recipients of social assistance between 1989 and 2002 in Sweden. This change is described as a process where the municipalities gradually take greater responsibility for the labour market policies. This group of unemployed is categorized as a particularly problematic group and has been referred to the
The continuing growth of female life expectancy has resulted in a marked increase of women in years beyond the menopause. Women can nowadays expect to live one-third of their lives in a potential hormonal deficiency state. Women over 50 comprise 17% of the total population of any country in the modern western world. Any decision regarding their health issues will have a great impact on our limited
Intrastriatal delivery of the tyrosine hydroxylase gene by viral vectors is being explored as a tool for local delivery of L-dopa in animals with lesions of the nigrostriatal pathway. The functional effects reported using this approach have been disappointing, probably because the striatal L-dopa levels attained have been too low. In the present study, we have defined a critical threshold level of
Popular Abstract in Swedish Malign hypertermi, ärftligt och farligt vid narkos – hur diagnostiseras det ? I april 1960 sövdes en yngling i Australien. Han var mycket orolig därför att tio släktingar dött av eter-narkos. Han sövdes i stället med ett nytt medel – halotan, det höll på att kosta även honom livet. En kortfattad fallbeskrivning i Lancet fick stor uppmärksamhet och på andra ställen i väMalignant hyperthermia (MH) susceptibility is a rare inherited muscular disorder, which may cause a lethal increase in metabolism during anaesthesia with certain commonly used anaesthetic. Susceptible individuals are without any signs or symptoms. It is important to identify individuals at risk, since the MH reaction is preventable. Susceptibility to MH is diagnosed with an in vitro contracture te
OBJECTIVES: Non-heart-beating donation (NHBD) has the potential to increase the number of patients treated with lung transplantation. Our study investigated, in a simulated clinical situation in the uncontrolled NHBD setting, whether or not heparin administration after death affects the donor lung function. METHODS: Twelve Swedish domestic pigs underwent ventricular fibrillation and were left unto
Purpose – Despite a growing interest in both women and university academic entrepreneurship, there are very few studies addressing women's academic entrepreneurship. The authors address this gap by focusing on university incubators for women's academic entrepreneurship. The purpose of this paper is to examine and analyze the significance of university incubators for the promotion and development o
BACKGROUND: Measuring microstructure alterations with diffusion tensor imaging in PD is potentially a valuable tool to use as a biomarker for early diagnosis and to track disease progression. Previous studies have reported a specific decrease of nigral fractional anisotropy in PD. However, to date the effect of disease progression on nigral or striatal diffusion indices has not been fully explored
Biomolecular and pharmaceutical downstream processing is dominated by chromatographic separation, which is associated with high product quality, low capacity and high costs. The separation can be optimized to minimize the costs while achieving a high purity. This paper presents an experimental validation of a discretized multi-level elution (DiME) trajectory, implemented on commercially available
All industrial facilities and large warehouses require some sort of lighting solution. They have ongoing activities with workers and trucks moving around at various speed, and to avoid accidents these lighting solutions are often very bright and energy consuming. The most common solution is fluorescent light. These lights are energy consuming and not dimmable. Turning these off by night or when th
