I en tid då AI-språkmodeller används alltmer i vår vardag, blir det relevant att undersöka hur det påverkar samhället. Denna studie undersöker, utifrån teorier om etik och jämställdhet, hur AI-språkmodeller i sina texter ger uttryck för mångfald, icke-diskriminering och rättvisa. Studien fokuserar på att identifiera och analysera förekomsten av könsbias i AI-språkmodellernas svar samt hur det påverkar människors förtroende för dessa system. En fallstudie genomfördes på tre AI-språkmodeller - ChatGPT 3.5, Gemini och Llama-2 70B, där data insamlades via intervjuer med dessa modeller. Därefter gjordes intervjuer med mänskliga informanter som reflekterade över AI-språkmodellernas svar. AI-språkmodellerna visade en obalans i hur de behandlar kvinnor och män vilket kan förstärka befintliga könsstereotyper. Detta kan påverka människors förtroende för AI-språkmodeller och informanterna lyfte problematiken om vad neutralitet och rättvisa innebär. För att skapa mer ansvarsfulla och rättvisa AI-system krävs medvetna insatser för att integrera etiska och jämställdhetsperspektiv i AI-utveckling och användning. / In a time when Large Language Models (LLMs) are increasingly used in our daily lives, it becomes important to investigate how this affects society. This study examines how LLMs express diversity, non-discrimination, and fairness in texts, based on theories of ethics and gender equality. The study focuses on identifying and analyzing the presence of gender bias in the responses of LLMs and how this impacts people's trust in these systems. A case study was conducted on three LLMs: ChatGPT 3.5, Gemini, and Llama-2 70B, where data was collected through interviews with them. Subsequently, interviews were conducted with human informants who reflected on the LLMs’ responses. The LLMs showed imbalance towards gender, potentially reinforcing existing gender stereotypes. This can affect people's trust in LLMs, and the informants highlighted the issue of what neutrality and fairness entail. To create more responsible and fair AI systems, conscious efforts are required to integrate ethical and equality perspectives into AI development and usage.

Recently, South African company law underwent a dramatic overhaul through the introduction of the Companies Act 71 of 2008. Central to company law is the promotion of corporate governance: companies no longer are accountable to their shareholders only but to society at large. Leaders should direct company strategy and operations with a view to achieving the triple bottom-line (economic, social and environmental performance) and, thus, should manage the business in a sustainable manner. An important question in company law today: In whose interest should the company be managed? Corporate governance needs to address the entire span of responsibilities to all stakeholders of the company, such as customers, employees, shareholders, suppliers and the community at large. The Companies Act aims to balance the rights and obligations of shareholders and directors within companies and encourages the efficient and responsible management of companies. The promotion of human rights is central in the application of company law: it is extremely important given the significant role of enterprises within the social and economic life of the nation. The interests of various stakeholder groups in the context of the corporation as a “social institution” should be enhanced and protected. Because corporations are a part of society and the community they are required to be socially responsible and to be more accountable to all stakeholders in the company. Although directors act in the best interests of shareholders, collectively, they must also consider the interests of other stakeholders. Sustainable relationships with all the relevant stakeholders are important. The advancement of social justice is important to corporations in that they should take into account the Constitution, labour and company law legislation in dealing with social justice issues. Employees have become important stakeholders in companies and their needs should be taken into account in a bigger corporate governance and social responsibility framework. Consideration of the role of employees in corporations entails notice that the Constitution grants every person a fundamental right to fair labour practices. Social as well as political change became evident after South Africa's re-entry into the world in the 1990s. Change to socio-economic conditions in a developing country is also evident. These changes have a major influence on South African labour law. Like company law, labour law, to a large extent, is codified. Like company law, no precise definition of labour law exists. From the various definitions, labour law covers both the individual and collective labour law and various role-players are involved. These role-players include trade unions, employers/companies, employees, and the state. The various relationships between these parties, ultimately, are what guides a certain outcome if there is a power play between them. In 1995 the South African labour market was transformed by the introduction of the Labour Relations Act 66 of 1995. The LRA remains the primary piece of labour legislation that governs labour law in South Africa. The notion of industrial democracy and the transformation of the workplace are central issues in South African labour law. The constitutional change that have taken place in South Africa, by which the protection of human rights and the democratisation of the workplace are advanced contributed to these developments. Before the enactment of the LRA, employee participation and voice were much-debated topics, locally and internationally. In considering employee participation, it is essential to take due cognisance of both the labour and company law principles that are pertinent: the need for workers to have a voice in the workplace and for employers to manage their corporations. Employee participation and voice should be evident at different levels: from informationsharing to consultation to joint decision-making. Corporations should enhance systems and processes that facilitate employee participation and voice in decisions that affect employees. The primary research question under investigation is: What role should (and could) employees play in corporate decision-making in South Africa? The main inquiry of the thesis, therefore, is to explore the issue of granting a voice to employees in companies, in particular, the role of employees in the decision-making processes of companies. The thesis explores various options, including supervisory co-determination as well as social co-determination, in order to find solutions that will facilitate the achievement of employee participation and voice in companies in South Africa. / LLD, North-West University, Potchefstroom Campus, 2015

No. of bitstreams: 1 Henrique Araujo Costa.pdf: 2539931 bytes, checksum: 9c873ec9e2f361932a9e422dd0b34bea (MD5) Previous issue date: 2012-05-03 / This text proposes a comparative study of English and Brazilian civil procedure. The research approaches the judge powers, specifically the case management powers. Considering the issue s delimitation, new statutes and its practice are compared through the perspective of both countries. In conclusion, these judge powers have become similar due to the blending practices seen among different law families, as well as between different countries of the same family. However despite the convergence towards strengthening these powers the problems to be solved by these countries have distinct roots. In England the cost problem is the biggest one, while in Brazil the biggest problem is the delay. Moreover, despite their early convergence, the cultural roots of each system keep them somehow apart from one another. Thus it is not possible to state which would the best system (since they are unique) and the adoption of the English model by the Brazilian legislation should be done with caution (since the problems to be solved are different) / O presente trabalho é uma proposta de estudo comparado do direito processual civil inglês e do brasileiro. A tese é centrada no tema dos poderes do juiz, notadamente nos case management powers. Dentro do recorte proposto, são comparadas as normas e a prática judicial recentemente instituídas pelo direito de cada um dos mencionados países. Conclui-se que os poderes desses juízes tornaram-se bastante semelhantes em decorrência da assimilação mútua de práticas judiciais entre diferentes famílias do direito, bem como entre países distintos de mesma família. No entanto a despeito da convergência em torno do fortalecimento dos poderes do juiz os problemas a serem solucionados pelos referidos países têm raízes distintas. A Inglaterra tem como maior problema o custo, enquanto o Brasil tem como maior problema a demora. Ademais, a raiz cultural de cada sistema os mantém de alguma forma diferentes, apesar da aproximação recente. Por isso não é possível dizer qual dos sistemas seja melhor (já que são incomparáveis) e eventual importação do modelo inglês pela legislação brasileira precisaria ser feita com ressalvas (já que os problemas a serem solucionados são distintos)

The legal historical development of fairness in the South African common law of contract is investigated in the context of the political, social and economic developments of the last four centuries. It emerges that the common law of contract is still dominated by the ideologies of individualism and economic liberalism which were imported from English law during the nineteenth century. Together with the theories of legal positivism and formalism which are closely related to parliamentary sovereignty and the classical rule of law, these ideals were transposed into the common law of contract through the classical model of contract law which emphasises freedom and sanctity of contract and promotes legal certainty. This approach resulted in the negation of the court’s equitable discretion and the limitation of good faith which sustain the social and economic inequalities that were created under colonialism and exacerbated under apartheid rule. In stark contrast, the modern human rights culture grounded in human dignity and aimed at the promotion of substantive equality led to the introduction of modern contract theory in other parts of the world. The introduction of the Constitution as grounded in human dignity and aimed at the achievement of substantive equality has resulted in a sophisticated jurisprudence on human dignity that reflects a harmonisation between its Western conception as based on Kantian dignity and ubuntu which provides an African understanding thereof. In this respect, ubuntu plays an important role in infusing the common law of contract with African values and in promoting substantive equality between contracting parties in line with modern contract theory. It is submitted that this approach to human dignity should result in the development of good faith into a substantive rule of the common law of contract which can be used to set aside an unfair contract term or the unfair enforcement thereof. / Private Law / LL.

Les accords multilatéraux sur l’environnement sont généralement caractérisés par leur autorité normative atténuée en raison des difficultés pour les États de garantir leur application effective et efficace. La procédure de non-conformité, expérimentée pour la première fois par le Protocole de Montréal sur les substances qui appauvrissent la couche d’ozone et étendue depuis, tente d’apporter des solutions appropriées aux particularismes de cette branche du droit international public. L’étude de son développement, de son évolution et de sa sophistication à travers sa nature, sa place et sa fonction permet ainsi de déterminer si cette technique exécutive contribue au renforcement de l’autorité des accords multilatéraux sur l’environnement. / Multilateral agreements on the environment are generally characterized by their normative authority diminished because of the difficulties for states to ensure their effective implementation and efficiency. The non-compliance procedure, for the first time experienced by the Montreal Protocol on Substances that Deplete the Ozone Layer and extended since then, attempts to provide appropriate solutions to the peculiarities of this branch of public international law.The study of its development, its evolution and sophistication through its nature, its place and function and to determine whether this technique helps to strengthen executive authority of multilateral environmental agreements.

This Doctoral thesis entitled the Constitutionality of Employers' Investigative Procedures and Disciplinary Hearing Processes with Specific Reference to Dismissal of Employees on the Basis of Criminal Misconducts in South Africa, focusses on individual labour law principles of fair labour practices entrenched in section 23(1) of the Constitution. The thesis deals with fairness in situation where an employee who is suspected of committing a criminal act is investigated and subsequently goes through a disciplinary hearing for dismissal. It determines the extent to which an employee’s criminal guilt is decided before dismissal. As such, the thesis is based upon South African judicial interpretation of the right to fair dismissal. In the process the thesis examines the application of principles informing the employer’s duty to provide fair reason concerning the dismissal of employees criminal suspects. In examining if employers observe constitutional transformative objective when conducting criminal investigations and disciplinary hearings - the thesis reviews the extent to which the employer respects constitutional rationales of equity based on the principles of natural justice. These natural justice principles are the basis upon which section 23(1) fairness is founded. Section 23 (1) is implemented through the LRA provisions. The thesis then concludes that, only one principle of natural justice - audi alteram partem is respected within employer flexibility-based fairness while the other principle - nemo judex in propria sua causa is ignored. It is this denial that causes serious procedural challenges in the quest for equity intended in section 23(1) fair labour practices. It is upon these foundational equity concerns that this thesis opposes the flexibility in employer’s criminal investigations and disciplinary hearing processes entrenched in item 4 (1) of Schedule 8 of the LRA fair procedure for dismissal of employees suspected of criminal acts. The thesis interlinks labour law and criminal law to advocate for the missing constitutionally justiciable fairness for employees who have committed criminal misconducts. It argues that the current judicial interpretation of labour law fairness is based upon the principle of flexibility underlying dismissals, asserting that fairness based on flexibility breeds informal procedural processes which exempt employers from observing crucial constitutional fairness principles expressed through proportionality-based prescripts. The thesis concludes that the practice of including the right against self-incrimination in employment law, done in other common law countries be introduced into the South African labour law through section 39 of the Constitution so that the identified procedural challenges are regulated. / Mercantile Law / LL.D.

<p dir="ltr">Several incidents report misuse of synthetic speech for impersonation attacks, spreading misinformation, and supporting financial frauds. To counter such misuse, this dissertation focuses on developing methods for speech forensics. First, we present a method to detect compressed synthetic speech. The method uses comparatively 33 times less information from compressed bit stream than used by existing methods and achieve high performance. Second, we present a transformer neural network method that uses 2D spectral representation of speech signals to detect synthetic speech. The method shows high performance on detecting both compressed and uncompressed synthetic speech. Third, we present a method using an interpretable machine learning approach known as disentangled representation learning for synthetic speech detection. Fourth, we present a method for synthetic speech attribution. It identifies the source of a speech signal. If the speech is spoken by a human, we classify it as authentic/bona fide. If the speech signal is synthetic, we identify the generation method used to create it. We examine both closed-set and open-set attribution scenarios. In a closed-set scenario, we evaluate our approach only on the speech generation methods present in the training set. In an open-set scenario, we also evaluate on methods which are not present in the training set. Fifth, we propose a multi-domain method for synthetic speech localization. It processes multi-domain features obtained from a transformer using a ResNet-style MLP. We show that with relatively less number of parameters, the proposed method performs better than existing methods. Finally, we present a new direction of research in speech forensics <i>i.e.</i>, bias and fairness of synthetic speech detectors. By bias, we refer to an action in which a detector unfairly targets a specific demographic group of individuals and falsely labels their bona fide speech as synthetic. We show that existing synthetic speech detectors are gender, age and accent biased. They also have bias against bona fide speech from people with speech impairments such as stuttering. We propose a set of augmentations that simulate stuttering in speech. We show that synthetic speech detectors trained with proposed augmentation have less bias relative to detector trained without it.</p>
