Since the 1950s the Ngorongoro Conservation Area (NCA) has experienced several changes in land use policy. In the early 1990s the NCA’s policy was changed for the last time and the area became considered an experimental multiple land use system. This has resulted in conflict between the government and conservationist groups, who argued that allowing people to reside within the protected area will

Purpose: The purpose of this thesis is to describe sustainability reporting practices in Brazilian corporations listed on B3. Methodology: The investigation for thesis was based on a content analysis. Sustainability information was defined according to the GRI standards provided by the Global Reporting Initiative and measured through the number of pages, words, tables, figures and diagrams. Theore

In this study, the relationship between the returns of stock indices for renewable energy, oil & gas and technology is analysed in a European context with the use of a DCC GARCH model. Results show that conditional correlations peaked during four years following the 2008 financial crisis but has since then reverted to pre-crisis levels. Hedge ratios imply that renewable energy stocks can be sh

Detta examensarbete undersöker hur ett visuellt designverktyg för byggande av användargränssnitt till iOS, Android, och webben kan konstrueras. Även fast det finns en hel del verktyg för att designa och bygga mobil- och webbappar, så finns det i nuläget inga visuella designverktyg för att bygga en gemensam app för alla tre plattformar. Utöver detta, så undersöker arbetet potentiella lösningar till This thesis investigates how a visual design tool for building cross-platform application interfaces for iOS, Android, and web can be constructed. While there are plenty of tools for building and designing mobile and web apps, there are currently no visual design tools for building cross-platform apps for all three platforms. Beyond this, the thesis explores potential solutions for problems relat

Bus Rapid Transit (BRT) är en benämning på ett högkvalitativt kollektivtrafiksystem som utvecklades under mitten av 1900 – talet och blev känt efter att det framgångsrikt implementerades i staden Curitiba i Brasilien. I Sverige används BRT som ett komplement till övrig kollektivtrafik medan det i stora städer runt om i världen fungerar som stommen i kollektivtrafiksystemet. För BRT i Sverige finnsBus Rapid Transit (BRT) is a name for a high – quality public transport system that was developed in the middle of the 19th century and became known after it was successfully implemented in the city of Curitiba in Brazil. In Sweden, BRT is used as a complement to other public transport, while in large cities around the world it functions as the frame of the public transport system. For BRT in Swed

What do customers want from an energy supplier application? To meet the increasing digitalization of the society, the energy supplier Kraftringen strives to create a new application that will match the customer’s needs and Kraftringen’s vision. This thesis was performed in order to present a user interface proposal of Kraftringen’s new application, to improve the user experience. The goals include

Latin America is and has been one of the most unequal regions in the World. Since the end of the Second World War, income inequality has been influenced by the high dependency on exports of agricultural products and raw materials, an early deindustrialization and the rise of low productivity service sectors. In this regard, this study aims to understand the impact of this structural change on inco

Exponering av polyklorerade bifenyler (PCB) kan orsaka hälsoeffekter hos människor. PCB från byggnadsmaterial har visats kunna läcka ut i inomhusluften. Det finns dock inga riktvärden för PCB i inomhusluften i Sverige. Studiens första syfte är att sammanställa och analysera riktvärden från andra länder. Studiens andra syfte är att uppskatta av hur många byggnader i Sverige (magnitud) som kan ha ko

Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t

The personal is still political as heterosexual romantic relationships are permeated by gender power dynamics. Previous research has shown that men tend to exploit women’s love, appropriate their care, and not reciprocate. This study looks at the impact of feminist values on these established patterns in Switzerland, a country known for being one of the last in western Europe to give women the rig

In this thesis, we consider a 2-Higgs-doublet model with a gauged Froggatt-Nielsen mechanism as an extension of the standard model. We assume that (i) the theory at the electroweak scale is the low energy limit of a theory defined at a scale $\Lambda_{FN}$ (ii) the Yukawa couplings at $\Lambda_{FN}$ are generated by the Froggatt-Nielsen mechanism. The first assumption is enforced by requiring that

Syftet med denna studie var att undersöka hur homosexuella män upplever surrogatmoderskap samt hur de påverkas av samhällets syn på surrogatmoderskap. Jag tar i detta sammanhang upp förarbetet - Olika vägar till föräldraskap (SOU 2016:11) och hur rapporteringen från olika media påverkar parens inställning i surrogatmoderskapsfrågan. Materialet i denna studie består av kvalitativa intervjuer med ho

Female entrepreneurs have been reported to choose self-employment for a variety of reasons, such as the flexibility of combining work and childcare. However, paradoxically female entrepreneurs may face double-bind situation where they are responsible for their business and are primary care givers of the family. Family farming is considered to be a very masculine occupation and the rural agricultur

This paper contributes to sustainability transitions studies in delivering stronger focus and relevance on culture and discursive features to apprehend social resistances towards transition agendas, and the unprecedented emergence of the challenging antagonism of the ‘end of the world’ versus ‘the end of the month’ revealed by the case study of the Yellow Vests crisis in France since November 2018

This thesis proposes a new effective Hamiltonian to represent the interactions taking place in the atomic nucleus. This estimated Hamiltonian is analogous to the Pairing-Plus-Quadrupole model and this work is focused exclusively on the quadrupole part, with the aim of describing nuclear structure in a computationally efficient way. We have compared the accuracy of our proposed expression with the

Kvantkromodynamik har blivit accepterad som den mest välfungerande teorin för den starka växelverkan. Vid höga energier kan kvarkarna i viss mån ses som fria partiklar och den starka kopplingskonstanten,αs, blir så pass liten att kvantkromodynamiken kan analyseras med en expansion i αs, en procedur känd som störningsteori. Denna metod fungerar inte längre vid låga energier då αs kan närma sig ett We perform a fit to three loop order (NNNLO) in Chiral perturbation theory of the pion mass and decay constant. In particular we investigate if the NNNLO fit is an improvement of the fit to two loop order (NNLO) to lattice QCD data, which was done in a lattice gauge group collaboration. We take several steps to improve our fits, one of them being the inclusion of finite volume corrections. They t

The literary heroic ideal changed with the Great War, as the Victorian hero ideal was no longer plausible in a post-war world. The new ideal was pacifist and non-heroic but not everyone who had been through the Great War agreed that there was no heroicism. This essay discusses the development of the heroic ideal in the mid twentieth century in relation to the two brothers Boromir and Faramir in J.
