The EU Taxonomy on Sustainable Finance : A Major Stride Forward or a Nightmare in Practice? / EU Taxonomi för hållbara investeringar : Ett stort steg framåt eller en mardröm i praktiken?

Wallhed, Niklas January 2021 (has links)
To limit the effects of climate change and keep the global mean temperature increase of below 1.5 °C in the year 2100, the financial markets need to shift investments into low-carbon business and technologies. By integrating sustainability assessments into traditional investment analysis, sustainable investing is in this case a concept that can be used to enable this transition. The EU Taxonomy on sustainable finance is a tool and future mandatory regulation that aims to highlight sustainable investing and to help different companies, investors and project promoters make investment decisions that align with the transition to a low-carbon society. This study aims to describe how the EU taxonomy can be related to sustainable investments, and to examine how companies in different sectors are evaluated using the EU Taxonomy by using companies included in a sustainability fund as a case study. Furthermore, the study aims to examine whether the EU Taxonomy is in line with the Industrial Ecology concepts of Life cycle thinking and weak/strong sustainability. The results of the literature study of the EU Taxonomy together with the case study suggests that the implementation of the EU Taxonomy into EU regulation will lead to a greater integration of sustainable investing within the EU. Furthermore, the EU Taxonomy does in theory integrate Life cycle thinking as well as possess a strong view on sustainability. However, this does not translate into practice as the practical implementation of the EU Taxonomy as it stands right now does not implement these concepts. The results of the case study showed that there are issues associated with accessing company specific information, as the analyzed companies did not disclose how their operations relate to the EU Taxonomy. Moreover, the case study indicated that some sectors have an easier time being considered environmentally sustainable by the EU Taxonomy. The EU Taxonomy is a step in the right direction towards increased integration of environmental sustainability into investments, however, the tool and regulation as it stands right now leaves much to be desired. / För att hålla den globala medeltemperaturen under en ökning på 1.5 °C till år 2100, måste den finansiella marknaden investera i företag och teknologier som bidrar till en minskning av växthusgasutsläpp globalt. Hållbara investeringar är ett koncept som tar hänsyn till b.la utsläpp av växthusgaser i investeringsbeslut, vilket kan möjliggöra denna övergång till hållbarare samhälle. EU:s Taxonomi om hållbara investeringar är ett ramverk och framtida reglemente som ämnar att möjliggöra och hjälpa företag, investerare och projektansvariga att investera mer miljömässig hållbart. Denna studie syftar till att förklara hur EU Taxonomin kan relateras till hållbara investeringar, samt att examinera hur företag i olika sektorer kan utvärderas med hjälp av EU Taxonomin genom att genomföra en casestudie på företag inkludera i en hållbarhetsfond. Vidare ämnar denna studie examinera om EU Taxonomin är i linje med industriell ekologi med koncepten livscykeltänkande (en: Life Cycle Thinking) samt stark och svag hållbarhet. Resultatet indikerar att implementeringen av EU Taxonomin kommer att leda till en ökad integrering av hållbara investering inom EU. Vidare indikerar resultatet att EU Taxonomin har som mål att ta hänsyn till livscykeltänkande och vara i linje med stark hållbarhet, men att denna målsättning inte är inkluderat i det praktiska verktyget som EU Taxonomin använder. Resultatet av casestudien visar att det finns problem kopplade till att bedöma hur väl företag tar hänsyn till kriterierna inkluderade i EU Taxonomin, då företag inte delger den information som behövs för att göra denna bedömning. Vidare så indikerade casestudien att vissa sektorer kommer ha det lättare när det kommer till att vara i linje med EU Taxonomins kriterier. Avslutningsvis så är EU Taxonomin ett steg i rätt riktning när det kommer till att integrera miljöaspekter i investeringar, men det praktiska verktyget och ramverk som det ser ut just nu skulle kunna vara mer utvecklat och mer strikt i praktiken.

Le mythe de la femme Potomitan aux Antilles et de la Strong Black Woman aux États-Unis : une recherche-création entre cinéma de fiction et constat social

Bique, Solène 04 1900 (has links)
Mémoire en recherche-création. Co-direction. / Basé sur une approche singulière, personnelle et interdisciplinaire, le présent mémoire de recherche-création interroge l’évolution des représentations cinématographiques associées aux femmes noires, largement répandues dans le cinéma américain, français et antillais. Cette étude-essai s’appuie plus particulièrement sur les liens que maintiennent les mythes respectifs de la Strong Black Woman dans un contexte nord-américain et celui de la femme Potomitan antillaise, en retraçant : leur historicité commune bien que géographiquement éparse, les valeurs de résilience et de sacrifice qu’elles partagent, mais aussi les limites sous-jacentes que révèlent l’utilisation de ces deux figures au cinéma. Pour comprendre l'ampleur de l'influence cinématographique et sociétale de ces mythes, il est essentiel d'examiner non seulement les contextes postcoloniaux dont ils sont issus et dans lesquels ils ont évolué, mais aussi les théories féministes qui prennent en compte, ou non, la dimension raciale de ces questions. Il faut également considérer la persistance des stéréotypes qui associent ces femmes et les personnages qu'elles interprètent à l'écran à des conceptions figées et racistes. Rythmée par le dialogue qu’entretiennent les deux composantes de ce mémoire-création, alliant une étude scientifique basée sur une méthodologie comparative à la réalisation d’un court-métrage de fiction, cette réflexion apporte une critique quant au rôle que jouent de telles représentations audiovisuelles dans la construction identitaire et la perception sociale de ces femmes et des communautés afro-descendantes auxquelles elles appartiennent. Ce faisant, il s’agit ici de révéler les lacunes palpables qui animent les récits cinématographiques qui en sont faits, ainsi que leur manque prégnant de subtilité et d’inclusivité. En outre, nous suggérons d'examiner des films qui adoptent une approche moderne de ces concepts. / Based on a unique, personal, and interdisciplinary approach, this present research-creation thesis examines the evolution of cinematic representations associated with Black women, widely prevalent in American, French, and French Caribbean cinema. This study-essay relies specifically on the links between the myths of the Strong Black Woman in a North American context and that of the Potomitan woman in the Caribbean, tracing their common historicity despite being geographically opposed, the values of resilience and sacrifice they share, as well as the underlying limitations revealed by using these two figures in cinema. In order to grasp the extent of the cinematic and societal influence of these myths, it is essential to consider not only the postcolonial contexts from which they originate and within which they have evolved but also the feminist theories that take into account, or not, the racial dimension of these issues. Additionally, it is necessary to consider the persistence of stereotypes that associate these women and the fictional characters they embody on screen with fixed and racist conceptions. Structured by the dialogue between the two components of this research-creation, combining a scientific study based on a comparative methodology with the making of a fictional short film, this reflection provides a critique of the role played by such audiovisual representations in the construction of identity and social perception of these women and the Afro-descendant communities to which they belong, revealing the tangible shortcomings that animate the cinematic narratives surrounding them, as well as their lack of subtlety and inclusivity. Furthermore, we suggest examining films that advise a modern approach to these concepts.

Optical coupling effects between plasmon resonances in disordered metal nanostructures and a nanocavity

Öqvist, Elin January 2024 (has links)
Ultra-thin solar cells that incorporate earth-abundant and non-toxic materials are promising candidates in the endeavor toward sustainable energy harvesting. Methods to counteract the inevitable low absorption of thinner semiconductor layers are of high interest and have raised considerable attention in the research society. In an attempt to increase the absorption of these types of assemblies, optical coupling effects between the localized surface plasmon resonances (LSPR) of disordered Au nanostructures and a Fabry-Pérot cavity were studied using a previously established absorber/spacer/reflector stack. The disordered Au array was fabricated by evaporating a thin Au film on a substrate with a 55 nm SiO2 dielectric spacer and a 100 nm Al reflecting film, followed by thermal annealing. Nominal Au film thicknesses in the range of 5-25 Å and annealing temperatures of 200-500 oC were investigated. In situ spectroscopic ellipsometry measurements during the subsequent atomic layer deposition (ALD) of tin monosulfide (SnS) allowed analysis of how the optical properties of the SnS/Au absorber layer changed as a function of the growing SnS layer thickness. By employing the Transfer Matrix Method with the estimated optical properties from the in situ analysis, the absorptance of the absorber/spacer/reflector stacks was simulated as a function of the spacer thickness, revealing any signs of the characteristic anti-crossing behavior. It was discovered that a nominal Au film thickness of 25 Å, annealed at 450 oC, and coated with a SnS film of ∼13 nm primed toward the π-phase, resulted in strong optical coupling between the cavity mode and the LSPR. The energy difference at the avoided crossing in the specular reflectance measurement gave an estimated Rabi-splitting energy of 537 meV. This corresponded to about 40% of the original LSPR energy, placing itself within the ultra-strong coupling regime. To evaluate the relevance of the thin-layered structure in photovoltaic applications, more advanced computational methods are required to estimate the useful absorption that occurs in the SnS layer. Nevertheless, these results elucidate the realization of strong optical coupling effects between disordered Au nanostructures and a Fabry-Pérot cavity, and further the possibility of using scalable fabrication methods for this type of ultra-thin absorber/spacer/reflector stack.

Indigo children: gestalt therapeutic guidelines for parents and caretakers; A Christian Perspective.

Grobler, Hermanus Bosman 30 June 2003 (has links)
The motivation for this study was to challenge the Indigo Child phenomenon and to view it from a Christian perspective. Throughout the study the focus was on the researcher's opinion of Christianity, supported by other authors and the Bible. The assumption of the study was that Indigo Children were ordinary children whose behaviour was formed and reinforced by societal and parental influences and guidance. The purpose of the study was to set up guidelines for parents and caretakers in order to facilitate and recommend strategic action regarding the management of these children. Guidelines were set up by using a combination of Gestalt philosophy, a Christian perspective and existing guidelines for so-called Indigo Children. For the purpose of this study Thomas's developmental research and utilization model was applied to the intervention research approach. Semi-structured interviews were used in order to gain information regarding parental styles. The information gained was combined with information found in literature in order to set up guidelines for parents. / Social Work / M.Diac. (Play Therapy)

Duality investigations for multi-composed optimization problems with applications in location theory

Wilfer, Oleg 30 March 2017 (has links) (PDF)
The goal of this thesis is two-fold. On the one hand, it pursues to provide a contribution to the conjugate duality by proposing a new duality concept, which can be understood as an umbrella for different meaningful perturbation methods. On the other hand, this thesis aims to investigate minimax location problems by means of the duality concept introduced in the first part of this work, followed by a numerical approach using epigraphical splitting methods. After summarizing some elements of the convex analysis as well as introducing important results needed later, we consider an optimization problem with geometric and cone constraints, whose objective function is a composition of n+1 functions. For this problem we propose a conjugate dual problem, where the functions involved in the objective function of the primal problem are decomposed. Furthermore, we formulate generalized interior point regularity conditions for strong duality and give necessary and sufficient optimality conditions. As applications of this approach we determine the formulae of the conjugate as well as the biconjugate of the objective function of the primal problem and analyze an optimization problem having as objective function the sum of reciprocals of concave functions. In the second part of this thesis we discuss in the sense of the introduced duality concept three classes of minimax location problems. The first one consists of nonlinear and linear single minimax location problems with geometric constraints, where the maximum of nonlinear or linear functions composed with gauges between pairs of a new and existing points will be minimized. The version of the nonlinear location problem is additionally considered with set-up costs. The second class of minimax location problems deals with multifacility location problems as suggested by Drezner (1991), where for each given point the sum of weighted distances to all facilities plus set-up costs is determined and the maximal value of these sums is to be minimized. As the last and third class the classical multifacility location problem with geometrical constraints is considered in a generalized form where the maximum of gauges between pairs of new facilities and the maximum of gauges between pairs of new and existing facilities will be minimized. To each of these location problems associated dual problems will be formulated as well as corresponding duality statements and necessary and sufficient optimality conditions. To illustrate the results of the duality approach and to give a more detailed characterization of the relations between the location problems and their corresponding duals, we consider examples in the Euclidean space. This thesis ends with a numerical approach for solving minimax location problems by epigraphical splitting methods. In this framework, we give formulae for the projections onto the epigraphs of several sums of powers of weighted norms as well as formulae for the projection onto the epigraphs of gauges. Numerical experiments document the usefulness of our approach for the discussed location problems.
