Business-related human rights violations are a recurring problem in the world. Just over 10 years ago, Sweden adopted the UN's guiding principles for business and human rights, in 2015 Sweden presented an action plan for business and human rights, and in 2016 there was a law regarding sustainability reporting for companies.  The Swedish government repeatedly states that business and human rights go hand in hand and expresses high expectations for Swedish companies to respect human rights.  In order to carry out the study of both the Swedish state's and Swedish companies' compliance with the UN's guiding principles, the Uyghurs' exposure to forced labor in Xinjiang and three Swedish companies are used as study objects. The result of the study leaves much to be desired from the Swedish state's side, as it acted very passively in the matter.

The purpose of this work is study of mediation as a new methodological approach to interaction with audience of art museum. The first chapter is devoted to complex analysis of the spectrum of socio-cultural conditions that led to a change of visitor’s role in the museum communication and an emergence of a new vision of museum’s mission. A general characteristic is given of a new approach that focuses on the audience as a center of museum's activities and thus makes a search of new methods of interaction with the public a problem of current interest. The second chapter explores the concept of "cultural mediation": different connotations of the term are given and inconsistencies in its use are removed; an author’s definition of the concept is offered. In the third chapter key characteristics of mediation as a specific method of interaction with the public are analyzed, and this method is compared to the traditional forms of gallery education (guided tours, lessons). The task of applied research is to develop a curriculum of training of mediators for the 3rd Ural Industrial Biennale of Contemporary Art. The list of professional competences and goals of training for a mediator is formed based on the analysis of the experience of mediators at the Manifesta 10 Biennial and the study of the professional documents of the European associations of mediators. Additionally, the main principle of studying and representing works of art is explained, which is the basis of mediators training. / Целью работы является исследование медиации как нового методологического подхода к взаимодействию с аудиторией художественного музея. Первая глава посвящена обобщению и системному анализу спектра социо-культурных предпосылок, приведших к изменению роли зрителя в музейной коммуникации и возникновению нового представления о миссии музея. Дается общая характеристика нового подход, акцентирующего роль аудитории как центра деятельности музея и делающего актуальной проблему поиска новых методов взаимодействия со зрителем. Во второй главе исследуется понятие «культурной медиации»: разбираются различные коннотации термина и снимаются разночтения в его использовании, предлагается авторское определение понятия. В третьей главе анализируется специфика медиации как метода работы с публикой на музейной экспозиции, выявляются его отличия от традиционных форм образовательной деятельности в художественном музее (экскурсия, музейно-педагогическое занятие). Прикладной задачей работы является разработка учебной программы подготовки медиаторов для 3-ей Уральской индустриальной биеннале современного искусства. На основе анализа опыта медиаторов на Манифесте 10 и изучения профессиональных документов европейских ассоциаций медиаторов выделяются профессиональные компетенции и задачи подготовки медиатора для выставки современного искусства. Раскрывается принцип взаимодействия медиатора с произведениями (содержанием экспозиции) и их репрезентации, ложащийся в основу его профессиональной подготовки.

The text discusses the Framework for the Implementation of the Corporate Sustainability Due Diligence Directive (CSDD) proposed by the European Union. The directive, aligned with UN and OECD guidelines, imposes obligations on companies to ensure respect for human rights and the environment. The due diligence obligation involves identifying and addressing the negative impacts of business activities, establishing internal complaint mechanisms, and publicly communicating efforts. The directive emphasizes integrating these activities into corporate policies and strategic decisions throughout the value chain. Companies must assess and address negative impacts in their supply chains, with measures tailored to the severity, likelihood, size, resources, and capabilities of the undertaking. The text highlights the complexity of sustainability as a long-term, multifaceted process, calling for collective responsibility from various stakeholders to navigate challenges in ecological and digital transitions, social inclusion, and energy and food security.

Operating through complex supply chains and multiple jurisdictions, today’s business enterprises can outsource manufacturing to different parts of the world where they can take advantage of low labour- and production costs. In the global quest for businesses to maximise their profits, deteriorating working conditions for offshore labour workers are increasing the risks of human rights abuses. Such abuses often take the form of ‘modern slavery’, which refers to situations of exploitation in which labour workers are trapped and unable to leave due to threats, violence, deception, abuse of power or other forms of coercion. In 2015, the United Kingdom (UK) enacted the Modern Slavery Act (MSA), aimed at combatting modern slavery by requiring business enterprises to be transparent with the steps they have taken to ensure that modern slavery is not taking place within their supply chains. By putting pressure on business enterprises to display their actions taken to address adverse human rights impacts, the MSA has brought the responsibility of business enterprises to conduct ‘human rights due diligence’ (HRDD) – as stipulated in the UN Guiding Principles on Business and Human Rights (UNGPs) - into domestic law. While the MSA has been regarded as a ‘world-leading instrument’ and a ‘historic milestone’ by the UK government, its effectiveness in counteracting modern slavery has been questioned in various studies, pointing towards a risk that the MSA is allowing human rights abuses to prevail under a form of a legal veil. Bearing in mind the country’s long colonial history, the enactment of the MSA can be seen as carrying an important symbolic value for the UK when it comes to taking accountability for human rights abuses committed overseas. However, adopting weak or ineffective legislation could instead, paradoxically, reflect an interest by the UK government to maintain beneficial trade relationships based on exploitative working conditions in a manner that reflects a continuation of former colonial power structures. This thesis is set out to examine this potential paradox by analysing the MSA’s level of compliance with the UNGPs from a postcolonial perspective.

Text in Afrikaans / This study is aimed at the development of a guiding framework for fathers and their adolescent sons by focusing on male identity as the main binding factor in the relationship between father a and son. The establishment, as well as the confusion regarding male identity, have been stated as starting point and problem statement of the study. The need regarding the way in which the father and son can be guided within this dynamic relationship in order to establish male identity, has been stated as motivation for the study. The need regarding the guidance of fathers and their sons was thus the primary aim with the research question, namely what the most applicable factors in a guiding framework should be that would guide fathers and their sons in order to support the formation of male identity within the sons. The research methodology that has been followed, was from a Gestalt perspective as meta theoretical assumption from which qualitative, explorative and descriptive strategies were followed. The qualitative strategy consisted of an auto-ethnography and semi-structured interviews. The trustworthiness of the research has been strengthened by a quantitative component of the research by utilizing questionnaires, after which data was collected and analysed. A purposive sample was drawn that included respondents from the Drakenstein municipal area in the Boland district. Categories that were identified from data from the semi-structured interviews, as well as indicators from the questionnaires, have been integrated, from which propositions were constructed. Six themes and resulting guiding strategies were presented in the form of a guiding framework. / Hierdie studie is gerig op die ontwikkeling van 'n begeleidingsraamwerk vir vaders en hulle adolessente seuns deur te fokus op manlike identiteit as die samebindende faktor in die verhouding tussen vader en seun.

The theme running through this dissertation is intended to prove that the Supreme Court has a role to play in the promotion, enforcement and sustenance of a proper democratic system of government, good governance and fundamental human rights and freedoms in Ghana. The Study would therefore address the role of the Supreme Court in the development of Constitutional Law in Ghana, with particular emphasis on the court's contribution to the underlying concepts of the Fourth Republican Constitution of 1992; the guiding principles of constitutional interpretation and the vexed issue of whether the court should adopt a mechanical and literal approach to the interpretation of the Constitution or adopt a liberal, beneficent and purposive approach. The Supreme Court has asserted in the locus classicus decision: Tuffuor v Attorney-General [1980] GLR 637 that the 1979 Constitution as the supreme law, must be construed as a living political document capable of growth. Is there any evidence now to support that claim? The study shall also investigate the question of the power of the Supreme Court to review legislative and executive action. We shall also examine the role of the Supreme Court in the interpretation and enforcement of the Constitution and Fundamental Human Rights and Freedoms in relation to the rights and obligations of the individual and the State with the view to achieving good governance. The 1992 Constitution itself is founded on the premise that there are limitations to the enjoyment of fundamental human rights and freedoms. What is the extent of such limitations as determined by the Supreme Court? What has been the Supreme Court's contribution to the sustenance of political stability and democratic governance and, especially, in matters relating to coup d'etats and to enforcement of the Constitution itself as distinct from the enforcement of fundamental human rights and freedoms? Has the Supreme Court power to enforce the Constitution and the existing law where there is proven case of injustice and illegality? Has the Supreme Court power to enforce Directive Principles of State Policy as formulated in chapter 6 of the 1992 Ghana Constitution? / Jurisprudence / LL.D.

Light can exert optical forces on matter. In the macroscopic world these forces are minuscule, but on the microscopic or atomic scale, these forces are large enough to trap and manipulate particles. They may even be used to cool atoms to a fraction of a degree above absolute zero. This thesis details a number of experiments concerned with the optical manipulation of atoms and micron-size particles using free space light beams and photonic crystal fibres. Two atom guiding experiments are described. In the first experiment, a spatial light modulator is used to generate higher blue-detuned azimuthal Laguerre-Gaussian LG) beams, which are annular beams with a hollow core. These LG beams are then used to guide laser cooled rubidium-85 atoms within the dark core over a distance of 30 mm. The second atom guiding experiment involves attempting to guide laser cooled and thermal rubidium atoms through a hollow-core photonic crystal fibre using red-detuned light. Hollow-core photonic crystal fibres are fibres that are able to guide light with low attenuation within a hollow core. For this experiment a hot wire detection system was designed, along with a number of complex vacuum systems. The first dual-beam fibre trap for micron-size particles constructed using endlessly single-mode photonic crystal fibre (ESM-PCF) is described. The characteristics of dual-beam fibre traps are governed by the fibres used. As ESM-PCF has considerably different properties in comparison to conventional single- or multimode fibres, this dual beam ESM-PCF trap exhibits some novel characteristics. I show that the dual beam ESM-PCF trap can form trapping, repulsive and line potentials; an interference-free ‘white light’ trap; and a dual-wavelength optical conveyor belt.

La gyrocinétique est un modèle clef pour la microturbulence en physique des plasmas. Elle présente encore plusieurs difficultés, qui pourraient invalider ses équations. Ce rapport de thèse clarifie trois d'entre elles. Tout d'abord, une de des coordonnées causait des soucis, d'un point de vue tant physique que mathématique ; une coordonnée adéquate est introduite, qui dissipe les difficultés et explique les structures intrinsèques sous-jacentes. Ensuite, des relations de récurrence explicites sont obtenues pour tous les ordres du développement perturbatif. Enfin, en utilisant la structure hamiltonienne de la dynamique, le couplage plasma-champ électromagnétique est implémenté d'un façon plus adaptée, avec d'importantes conséquences sur les équations gyrocinétiques.Plusieurs autres résultats sont obtenus, e.g. sur l'origine de l'invariant adiabatique centre-guide, sur une transformation centre-guide minimale très efficace, ou sur un modèle hamiltonien intermédiaire entre Vlasov-Maxwell et la gyrocinétique, dont les caractéristiques de Vlasov contiennent à la fois la dynamique lente centre-guide et la dynamique rapide du gyro-angle. Diverses méthodes de réduction sont utilisées, développées ou introduites, e.g. une transformée de Lie du mouvement, un relèvement transférant les réductions de la dynamique des particules à la dynamique des champs, ou une troncature reliée à la fois à la théorie des contraintes de Dirac et à une projection sur une sous-algèbre. Outre la gyrocinétique, cela clarifie d'autres réductions hamiltoniennes en plasmas, e.g. pour une dynamique incompressible ou électrostatique, pour la MHD, ou pour des fermetures fluides avec tenseur de pression. / Gyrokinetics is a key model for plasma micro-turbulence. It still suffers from several issues, which could imply to reconsider the equations. This thesis dissertation clarifies three of them. First, one of the coordinates caused questions, both from a physical and from a mathematical point of view; a suitable constrained coordinate is introduced, which removes the issues from the theory and explains the intrinsic structures underlying the questions. Second, explicit induction relations are obtained to go arbitrary order in the perturbative expansion. Third, using the Hamiltonian structure of the dynamics, the coupling between the plasma and the electromagnetic field is implemented in a more appropriate way, with strong consequences on the gyrokinetic equations. Several other results are obtained, for instance about the origin of the guiding-center adiabatic invariant, about a very efficient minimal guiding-center transformation, or about an intermediate Hamiltonian model between Vlasov-Maxwell and gyrokinetics, where the characteristics include both the slow guiding-center dynamics and the fast gyro-angle dynamics. In addition, various reduction methods are used, introduced or developed, e.g. a Lie-transform of the equations of motion, a litfing method to transfer particle reductions to the corresponding Hamiltonian field dynamics, or a truncation method related both to Dirac's theory of constraints and to projections onto Lie-subalgebras. Besides gyrokinetics, this is useful to clarify other Hamiltonian reductions in plasma physics, e.g. for incompressible or electrostatic dynamics, for magnetohydrodynamics, or for fluid closures including moments of order two.

Le développement de différentes techniques pour contrôler les degrés de liberté internes et externes des molécules et pour produire (ultra-) froide, piège des moléculaire ensembles ouvrir des voies différentes à la physique et la chimie dans le régime de basse température. Il s'agit notamment de nombreux territoires en physique comme, phases quantiques de la matière, traitement de l'information quantique, les froides collisions moléculaires, les chimies froides et aussi de divers tests de haute précision pour la physique fondamentale. Cette thèse décrit diverses expériences de guidage et de décélération des faisceaux supersoniques d'atomes paramagnétiques à l’aide de champs magnétique inhomogène dépendent du temps. Ces champs magnétiques inhomogènes ont été utilisés pour exercer une force sur les atomes ou les molécules paramagnétiques, qui résultent de l'effet Zeeman. Le principe du ralentisseur Zeeman nouvellement développé est de produire un déplacement tridimensionnel du piège magnétique, à la vitesse initiale du faisceau. Le contrôle de la dépendance temporelle du champ magnétique nous permet de contrôler la vitesse du piège magnétique co-mobile, procurant ainsi une décélération d'une classe de vitesse du faisceau supersonique. Le piège magnétique co- mobile est déduit à partir d'une onde magnétique mobile, offrant un minimum de distorsion du piège lors de sa propagation. Les propriétés transverses du piège sont réglables grâce à un champ magnétique transversal quadrupolaire, qui peut être ajusté indépendamment des propriétés de vitesses et l'accélération du piège. Une grande part du travail de thèse a été consacrée à la conception, la réalisation et la construction du montage expérimental, consistant en un jet supersonique et en un dispositif complexe de bobines pour réaliser l’onde magnétique progressive, formant un piège magnétique mobile. Le jet froid pulsé d'atomes métastables est produit par expansion supersonique à travers une valve refroidie à l'azote liquide, excités dans l'état métastable par une décharge électrique. Nous avons guidé le jet d'argon au travers d’un tube capillaire le guidage et la décélération ont été démontrés. Le piège magnétique mobile est formé par la combinaison d'un champ magnétique quadrupolaire et d'un champ magnétique axial modulé spécialement. Le champ quadrupolaire est continu et un gradient de champ est dirigé seulement dans la direction transverse du jet. Le circuit plan produit une onde magnétique sinusoïdale avec un gradient de champ dans la direction axiale. Avec l'électronique fabriquée au laboratoire, ou peut produire une onde magnétique progressive d'amplitude 0.69T (avec un courant AC de 300A) et de fréquence 40 kHz. On obtient ainsi une onde qui se déplace à une vitesse de 464m/s. Plusieurs expériences de principe ont été réalisées en utilisant le jet froid pulsé d'argon métastable. Nous avons étudié les propriétés de guidage du quadrupole pour divers courants et pour différents atomes (hélium et argon) et comparé les résultats aux prédictions théoriques de simulations numériques. Le jet d'argon métastable a été guidé en 3D à des vitesses variées (464m/s, 400m/s, 392m/s) avec un décélérateur de 28cm de long. La température observée du paquet guidé est de 100mK. L'expérience de décélération a été réalisée avec le jet d'argon métastable depuis la vitesse de 400m/s jusqu’à 370m/s et depuis la vitesse de 392m/s jusqu’à 365m/s. Les résultats expérimentaux sont comparés avec les simulations numériques. / The development of various techniques to control both the internal and external degrees of freedom of molecules and to produce (ultra-) cold, trapped molecular ensembles open various avenues to physics and chemistry in the low temperature regime. These include many territories in physics like, quantum phases of matter, quantum information processing, cold molecular scattering, cold chemistry and also various high precision tests for fundamental physics.This thesis describes various guiding and deceleration experiments of supersonic beams of paramagnetic atoms using inhomogeneous time-dependent magnetic fields. Inhomogeneous magnetic fields have been used to exert a force on paramagnetic atoms or molecules, which derives from the Zeeman effect. The principle of the newly developed Zeeman decelerator is to produce a moving tridimensional magnetic trap, which moves at the initial velocity of the beam. The control of the time dependence of the magnetic field allows us to control the velocity of the so-called co-moving magnetic trap, thereby affording for a deceleration of a velocity class of the supersonic beam. The co-moving magnetic trap is inferred from a moving magnetic wave, offering a minimal distortion of the trap during its propagation. The transverse properties of the trap are tunable through a transverse quadrupolar magnetic field, which can be adjusted independently of the velocity and acceleration properties of the trap.Much of this thesis was devoted to the design, development and construction of the experimental setup consisting of a supersonic beam and complex coils to achieve a traveling magnetic wave. Using home-made electronics operating 300A AC currents at frequencies up to 40 kHz, the coils can produce a magnetic wave of amplitude 0.7T, moving at a controllable velocity up to 464m/s. Several proof-of-principle experiments have been carried out using a pulsed, cold beam of metastable atoms, excited in metastable states by an electric discharge during the supersonic expansion. We have studied the guiding properties of the quadrupolar magnetic field alone on two atomic beams (metastable helium and argon) and compared with the theoretical prediction of tridimensional numerical simulations. A supersonic beam of metastable argon atoms has been trapped in a co-moving trap at a constant velocity (464m/s, 400m/s, and 392m/s) using a 28cm-long prototype decelerator. The temperature of the guided beam packet is observed to be 100mK. Finally, Zeeman deceleration experiments have been done on metastable argon beams with an initial velocity of 400m/s, decelerated to various final velocities (392m/s, 370m/, and 365m/s). The experimental results are compared with tridimensional numerical simulations.Keywords: Supersonic beams, metastable atoms, cold molecules, atoms in inhomogeneous magnetic fields, transverse magnetic guide, co-moving magnetic trap, tridimensional guiding, Zeeman deceleration.
