Summaries in Afrikaans and English / Die tradisionele benadering tot bestuur het die Suid-Afrikaanse korrektiewe sisteem sedert sy ontstaan gedomineer. Die vraag wat ontstaan, is of daar enige praktiese, werkbare altematiewe is, veral omdat die huidige strategiese ingesteldheid, argitektuur en menslike hulpbronne onder verdenking is. Hierdie navorsing bevestig die vermoede dat 'n nuwe benadering tot strategie, struktuur, kultuur, bestuursfilosofie, werkspraktyke en mense te voorskyn kom en dat dit alleenlik gemobiliseer kan word deur organisasievernuwing. 'n Penologiese sisteem wat 'n deelnemende bestuursbenadering aanvaar, sal as 'n wereldleier geklassifiseer word. / The traditional approach to management has dominated the South African correctional system since its conception. The question arises whether there are any practical workable alternatives, especially as the present strategic intent, architecture and human resources are under suspicion. This research confirms the supposition that a new approach to strategy, structure, culture, management philosophy, work methods and people is emerging and that this approach can be enabled only by organisational renewal. A penological system that adopts a participative management approach would be classified as a world leader. / Penology / M.A. (Penology)

The study is conducted to determine practical modelling and simulation techniques to perform dynamic stability and performance analysis on a 3 Degrees of freedom aircraft model using a Modelica-based commercial tool called Modelon Impact. This study is based on a conceptual aircraft model where in-depth details about the aircraft configuration are unknown and the aim is to determine a suitable model that can capture the longitudinal dynamics and aerodynamic constraints of the aircraft during the conceptual design phase. Requirements include short execution time, easy model development, and minimal data requirements. Therefore, this thesis aims at developing plant and control architectures in  Modelon Impact which can be utilized for the rapid development of aircraft concepts with adequate fidelity in a longitudinal mission-based tracking environment. In a conceptual aircraft design environment, to identify a suitable methodology that mitigates the limitations of a traditional feedback controller, two methodologies are considered for comparison: Sequential DAE resolution (SDR) and Dynamic inversion (DI) control which is discussed from an object-oriented aircraft model. The advantages and shortcomings of each of the models discussed above are compared by conducting several experiments in increasing order of longitudinal mission complexity, and the most appropriate model among the two for a conceptual stage of aircraft design development is ascertained. The two methodologies discussed are compared for their level of complexity, code structure, readability, and ease of usability.

Les récentes percées technologiques dans les domaines de l’actionnement, de la perception et de l’intelligence artificielle annoncent une nouvelle ère pour l’assistance à la conduite et les véhicules hautement automatisés. Toutefois, dans un contexte où l’automatisation demeure imparfaite, il est primordial de s’assurer que le système d’automatisation de la conduite puisse maintenir la conscience de la situation du conducteur afin que ce dernier puisse accomplir avec succès son rôle de supervision des actions du système. En même temps, le système doit pouvoir assurer la sécurité du véhicule et prévenir les actions du conducteur qui risqueraient de compromettre sa sécurité et celle des usagers de la route. Il est donc nécessaire d’intégrer dès la conception du système automatisé de conduite, la problématique des interactions avec le conducteur en réglant les problèmes de partage de tâche et de degré de liberté, d’autorité et de niveau d’automatisation du système. S’inscrivant dans le cadre du projet ANR-CoCoVeA (Coopération Conducteur-Véhicule Automatisé), cette thèse se penche de plus près sur la question de la coopération entre l’automate de conduite et le conducteur. Notre objectif est de fournir au conducteur un niveau d’assistance conforme à ses attentes, capable de prendre en compte ses intentions tout en assurant un niveau de sécurité important. Pour cela nous proposons un cadre général qui intègre l’ensemble des fonctionnalités nécessaires sous la forme d’une architecture permettant une coopération à plusieurs niveaux de la tâche de conduite. Les notions d’attribution des tâches et de gestion d’autorité avec leurs différentes nuances sont abordées et l’ensemble des fonctions du système identifiées dans l’architecture ont été étudiées et adaptées pour ce besoin de coopération. Ainsi, nous avons développé des algorithmes de décision de la manœuvre à effectuer, de planification de trajectoire et de contrôle qui intègrent des mécanismes leur permettant de s’adapter aux actions et aux intentions du conducteur lors d’un éventuel conflit. En complément de l’aspect technique, cette thèse étudie les notions de coopération sous l’angle des facteurs humains en intégrant des tests utilisateur réalisés sur le simulateur de conduite dynamique SHERPA-LAMIH. Ces tests ont permis à la fois de valider les développements réalisés et d’approfondir l’étude grâce à l’éclairage qu’ils ont apporté sur l’intérêt de chaque forme de coopération. / The recent technological breakthroughs in the actuation, perception and artificial intelligence domains herald a new dawn for driving assistance and highly automated driving. However, in a context where the automation remains imperfect and prone to error, it is crucial to ensure that the automated driving system maintains the driver’s situation awareness in order to be able to successfully and continuously supervise the system’s actions. At the same time, the system must be able to ensure the safety of the vehicle and prevent the driver’s actions that would compromise his safety and that of other road users. Therefore, it is essential that the issue of interaction and cooperation with the driver is addressed throughout the whole system design process. This entails the issues of task allocation, authority management and levels of automation. Conducted in the scope of the projet ANR-CoCoVeA (French acronym for: "Cooperation between Driver and Automated Vehicle"), this thesis takes a closer look at the question of cooperation between the driver and automated driving systems. Our main objective is to provide the driver with a suitable assistance level that accounts for his intentions while ensuring global safety. For this matter, we propose a general framework that incorporates the necessary features for a successful cooperation at the different levels of the driving task in the form of a system architecture. The questions of task allocation and authority management are addressed under their different nuances and the identified system functionalities are studied and adapted to match the cooperation requirements. Therefore, we have developed algorithms to perform maneuver decision making, trajectory planning, and control that include the necessary mechanisms to adapt to the driver’s actions and intentions in the case of potential conflicts. In addition to the technical aspects, this thesis studies the cooperation notions from the human factor perspective. User test studies conducted on the SHERPA-LAMIH dynamic simulator allowed for the validation of the different developments while shedding light on the benefits of different cooperation forms.

Las acciones promocionales de las diversas plataformas online logran que el usuario considere realizar una compra no esperada. Sin embargo, en algunas ocasiones sienten temor con respecto al método de pago. Por ello, la mayoría de las empresas tienen certificado de protección de datos para que el usuario confíe en el sitio web y realice el proceso de compra. Estudios anteriores mencionan que las compras generan beneficios de placer a los consumidores online, lo cual hace referencia al valor hedónico. Dichos consumidores son captados por promociones online que incluyen obsequios, puesto que activan los deseos hedónicos. Además, existen usuarios que realizan actividades de compras orientadas a objetivos utilitarios. Dichos consumidores perciben un mayor nivel de riesgo en compras en línea. Por otro lado, existen barreras en las acciones promocionales, ya que algunos usuarios online no están dispuestos a comprar en línea debido a problemas relacionados con la privacidad de sus datos. A partir de ello, se puede interpretar que el comercio electrónico se puede concretar si los consumidores están satisfechos y se sienten seguros en el canal online. La investigación está enfocada en los usuarios que compran promociones de la categoría electrodomésticos en las páginas de ecommerce de los supermercados y tiendas por departamento de Lima metropolitana. El estudio es de tipo cuantitativo basado en una muestra de 400 participantes, los cuales mediante una encuesta se les evaluará su experiencia online. / The promotional actions of the various online platforms make the user consider making an unexpected purchase. However, sometimes they are fearful about the payment method. For this reason, most companies have a data protection certificate so that the user trusts the website and performs the purchase process. Previous studies mention that shopping generates pleasure benefits for online consumers, which refers to hedonic value. These consumers are captured by online promotions that include gifts, since they activate hedonic desires. In addition, there are users who carry out purchasing activities oriented to utilitarian objectives. These consumers perceive a higher level of risk in online purchases. On the other hand, there are barriers in promotional actions, as some online users are not willing to buy online due to problems related to the privacy of their data. From this, it can be interpreted that electronic commerce can be achieved if consumers are satisfied and feel safe in the online channel. The research is focused on users who buy promotions in the household appliances category on the ecommerce pages of supermarkets and department stores in metropolitan Lima. The study is quantitative based on a sample of 400 participants, who through a survey will evaluate their online experience. / Trabajo de investigación

La liberté de circulation et la liberté d’établissement sont reconnues comme fondamentales et intrinsèquement liées au principe de dignité humaine. Pourtant, au nom de la souveraineté nationale, les États imposent des limites à la mobilité humaine. La mobilité de la main-d’œuvre est nécessaire au fonctionnement de l’économie et peut répondre en partie aux enjeux de pénurie de travailleurs. Notre thèse propose une recherche en droit positif visant à circonscrire la portée du droit à la mobilité en droit canadien. De fait, l’article 6 (2) de la Charte canadienne des droits et libertés reconnaît aux citoyens et résidents permanents au Canada la liberté de circulation et le droit de gagner leur vie. Toutefois, l’alinéa 6 (3) a) de la Charte contient une restriction à ces droits. Les provinces demeurent autorisées à légiférer pour limiter la mobilité, tant qu’elles n’imposent pas de discrimination basée sur la province de résidence. Nous soutenons que dans l’état actuel de la jurisprudence canadienne, le droit à la mobilité n’est pas considéré comme une liberté fondamentale. Pour leur part, les accords de commerce entre les membres de la confédération, sur le plan national, et les accords bilatéraux, régionaux et multilatéraux entre le Canada et ses partenaires contiennent des dispositions encadrant la mobilité de la main-d’œuvre. Lors des négociations constitutionnelles qui ont précédé et suivi le rapatriement de la constitution canadienne en 1982, le développement de l’union économique au pays et l’inclusion du droit à la mobilité ont été au cœur des débats. Or l’analyse des décisions de la Cour suprême du Canada portant sur l’article 6 (2) démontre pourtant que c’est uniquement la non-discrimination sur la base de la province de résidence qui est garantie par la Charte. Les instruments internationaux relatifs aux droits de la personne établissent le droit à la mobilité comme un droit fondamental, mais la recension des différents accords de libre-échange permet de conclure que la mobilité de la main-d’œuvre est favorisée essentiellement pour répondre aux besoins économiques. Le droit à la mobilité ne devrait pas uniquement répondre aux besoins des aléas économiques. Dans cette perspective, la reconnaissance des compétences et des qualifications s’avère impérative pour que le droit à la mobilité soit réellement effectif. / The rights to move, the right to take up residence, and the right to gain a livelihood are recognized as fundamental and are intrinsically linked to the principle of human dignity. Yet, in the name of national sovereignty, states impose limits on human mobility. Labor mobility is a pillar of world economy and can address many aspects of workforce shortages. Our research examines current constraints to, and the scope of, the right to mobility under Canadian law. Indeed, section 6 (2) of the Canadian Charter of Rights and Freedoms recognizes the right to move and the right to gain a livelihood for citizens and permanent residents of Canada. However, section 6 (3) a) of the Charter contains a limitation on these rights. Provinces remain authorized to limit mobility, as long as they do not discriminate on the basis of province of residence. We argue that, as Canadian jurisprudence currently stands, mobility rights are not considered a fundamental freedom. On the other hand, trade agreements between members of confederation, at the national level, and bilateral, regional, and multilateral agreements between Canada and its international partners, contain provisions regulating labor mobility. During the constitutional negotiations that preceded and followed the repatriation of the Constitution Act, 1982, the development of the economic union in Canada and the inclusion of mobility rights were at the heart of the debate. However, an analysis of the Supreme Court of Canada's decisions on section 6(2) shows that the Canadian Charter guarantees non-discrimination on the basis of province of residence. International human rights instruments establish the mobility rights as a fundamental right, but a review of various free trade agreements suggests that labor mobility is promoted primarily to meet economic needs. Mobility rights should not uniquely answer economic requirements. Against this background, the recognition of skills and qualifications is imperative to ensure that mobility rights are effective.

When recently graduated psychologists leave the profession, it can have a negative impact on the quality and continuity of care as well as resulting in socioeconomic costs. This study set out to investigate what personal and contextual factors affect newly graduated psychologists' intention to leave the profession (ITLP) over time. Longitudinal data was collected using a survey over three waves: 2017, 2018 and 2019. The participants were newly graduated psychologists in Sweden (n=346) who had answered two consecutive surveys. Logistic regressions were made, with the dependent variable ITLP. The independent variables were: sector (public or private), occupational self-efficacy, work related psychological flexibility, role stress. emotional demands, job satisfaction, social support (from colleagues, supervisor and family), transition between studies and internship, transition between internship and employment and sickness absence. Results showed that job satisfaction, social support from supervisors and the transition between internship and employment had a significant effect on the newly graduated psychologists’ ITLP over time. Due to data limitations some hypothesized relationships might not have been detected. Further research is needed to clarify what affects psychologists’ ITLP over time. / Att psykologer väljer att lämna yrket kan påverka vårdkvalitet och kontinuitet, dessutom innebär det samhällsekonomiska kostnader. Denna studie undersöker vilka faktorer det är som påverkar huruvida psykologer har en intention att lämna yrket (ITLP) eller inte. Longitudinell data samlades in i tre omgångar: 2017, 2018 och 2019. Deltagare var nyligen examinerade psykologer i Sverige (n=346) som hade svarat på två efterföljande enkäter. Logistiska regressioner genomfördes med den beroende variabeln ITLP. De oberoende variabler var: sektor (offentlig eller privat), arbetsrelaterad self-efficacy, arbetsrelaterad psykologisk flexibilitet, rollstress, emotionella krav, arbetstillfredsställelse, socialt stöd (från kollegor, överordnad och familj), övergång mellan studier och praktisk tjänstgöring, övergång mellan praktisk tjänstgöring och arbete samt sjukfrånvaro. Resultatet visade att arbetstillfredsställelse, socialt stöd från överordnad och transitionen mellan praktisk tjänstgöring och arbete hade en signifikant effekt på ITLP över tid. Begränsningar i data kan ha gjort så att vissa av de samband som hypotiserats inte kunde identifieras. Mer framtida forskning behövs för att klargöra vilka faktorer som påverkar psykologers ITLP över tid.

[pt] As mídias sociais digitais fazem parte do dia a dia de muitas pessoas. Nestas mídias, as empresas também estão presentes, o que indica interesse destas em construir relacionamentos mais próximos com os consumidores, além de promover seus produtos/serviços. Este estudo tem como objetivo analisar a percepção de consumidores em relação aos anúncios nas mídias sociais digitais e avaliar se estes anúncios conseguem influenciar o comportamento de compra. Para entender esta influência, foi desenvolvido um modelo conceitual com os seguintes construtos: informatividade, entretenimento, irritação, credibilidade, incentivos, valor emocional, valor do anúncio e atitude em relação à anúncios em mídias sociais digitais. Foi aplicada uma survey online que resultou em uma amostra de 589 brasileiros que utilizam Instagram ou Facebook. Os dados levantados foram analisados através da modelagem de equações estruturais (SEM). Uma das contribuições teóricas deste estudo foi a proposta de analisar a influência do valor emocional sobre a atitude em relação aos anúncios em mídias sociais digitais, o que não foi identificado em estudos anteriores. Além disso, o resultado apontou que a informatividade, construto consolidado na literatura como antecedente de valor do anúncio e atitude, não apresentou efeitos significativos no modelo estimado. Ademais, foi estudada a moderação do tipo de mídia social digital (Facebook ou Instagram) sobre as relações propostas. Os resultados indicaram que, enquanto os usuários de Instagram percebem com mais intensidade o efeito do valor do anúncio sobre a intenção de compra, os usuários do Facebook percebem o efeito de atitude de forma mais intensa. O estudo também fornece contribuições gerenciais que permitem profissionais de marketing a desenvolverem anúncios em mídias sociais de forma mais eficaz. / [en] Digital social media is a daily part of many people s lives. Companies are also present in this type of media, which indicates their interest in building closer relationships with consumers, in addition to promoting their products/services. This study aims to analyze consumers perceptions of ads on digital social media and to assess whether these ads can influence purchase behavior. To understand this influence, a conceptual model was developed with the following constructs: informativeness, entertainment, irritation, credibility, incentives, emotional value, ad value and attitude towards digital social media ads. An online survey was conducted that resulted a sample of 589 Brazilians using Instagram or Facebook. The collected data were analyzed through the structural equation modeling (SEM). One of the theoretical contributions of this study was the evaluation of the influence of emotional value on attitude towards digital social media ads, a relationship that was not identified in previous studies. In addition, the results pointed out that informativeness, a construct consolidated in the literature as an antecedent of ad value and attitude, did not present significant effects in the estimated model. In addition, the moderating effects of the type of digital social media (Facebook or Instagram) on the proposed relationships were studied. The results indicated that while Instagram users perceive more strongly the effect of ad value on intention to buy, Facebook users perceive the effect of attitude more intensely. The study also provides managerial contributions that enable marketers to more effectively develop social media ads.

Many, if not all people have online social accounts (OSAs) on an online community (OC) such as Facebook (Meta), Twitter (X), Instagram (Meta), Mastodon, Nostr. OCs enable quick and easy interaction with friends, family, and even online communities to share information about. There is also a dark side to Ocs, where users with malicious intent join OC platforms with the purpose of criminal activities such as spreading fake news/information, cyberbullying, propaganda, phishing, stealing, and unjust enrichment. These criminal activities are especially concerning when harming minors. Detection and mitigation are needed to protect and help OCs and stop these criminals from harming others. Many solutions exist; however, they are typically focused on a single category of malicious intent detection rather than an all-encompassing solution. To answer this challenge, we propose the first steps of a framework for analyzing and identifying malicious intent in OCs that we refer to as malicious mntent detection framework (MIDF). MIDF is an extensible proof-of-concept that uses machine learning techniques to enable detection and mitigation. The framework will first be used to detect malicious users using solely relationships and then can be leveraged to create a suite of malicious intent vector detection models, including phishing, propaganda, scams, cyberbullying, racism, spam, and bots for open-source online social networks, such as Mastodon, and Nostr.
