According to Erikson (1968), adolescents and young people are greatly engaged in the process of identity development with the intentions to evade a state of diffusion and role confusion. Not much research in the areas of identity formation and career development has explored the possible relationship between these two phenomena. The purpose of this study was to investigate whether there is a relationship between gender identity formation (identity statuses) and career decision-making process among high school learners. In addition the study explored if there are gender differences between males and females on identity statuses, as well as on career decision-making process. A sample of 156 Grade 12 learners participated in the study. The Revised Extended Objective Measure of Ego Identity Status (Bennion & Adams, 1986) and the Study Choice Task Inventory were administered to the learners. Findings of the study showed correlation between the identity statuses of Diffusion, Foreclosure and Moratorium for males and females and the career decision–making process. No statistically significant differences were found between males and females on the variables, namely, identity statuses and aspects of career decision-making processes. Implications for theory and practice and recommendations for future research are provided.

Human immunodeficiency virus and acquired immune deficiency syndrome (hereafter HIV/AIDS) in South Africa are epidemic virus and disease respectively, item 1.1 of the EEA Code of Good Practice on Key Aspects of HIV/AIDS and Employment, 2000 states that HIV/AIDS are serious public health problems, which have socio-economic, employment and human rights implications on the society, employees inclusive. The Constitution of the Republic of South Africa, 1996, Employment Equity Act 55 of 1998, Labour Relations Act 66 of 1995 and Promotion of Equality and Prevention of Unfair discrimination 4 of 2000, international and regional instruments and standards provide protection to HIV positive employees in the workplace. Notwithstanding this plethora of legislation, employees are still faced with the problems of being stigmatised, unfairly discriminated against and ultimately dismissed from work for being HIV positive. Employees are subjected to HIV testing and the information about their HIV statuses is still being disclosed without their informed consent and their right to privacy and confidentiality may be violated. These possible violations of employees’ rights may affect the economy of the country. When employees are dismissed, the amount of production and profits for the employers decrease and as a result the government loses tax revenue, the unemployment and poverty rates increase. Hence it is imperative to investigate the problems of stigmatisation, unfair discrimination and dismissals in order to see to what extent are employees’ rights protected. There will be a comparative study in Canada which is experiencing the same problems as South Africa in order to find out how Canada can provide solution to South African problems. / LLM (Labour Law), North-West University, Potchefstroom Campus, 2015

Le cadre de pratique du judo est spécifique et met en scène des éléments qui rendent l'étude des divisions par sexe dans les clubs sportifs de judo particulièrement intéressante. En effet, la socialisation corporelle et l'assimilation des codes non-officiels de la pratique visent à asexuer les corps et les judokas et de ce fait, favorisent l'apparition de relations de sexe neutralisé entre les pratiquants. Ainsi, à partir d’une analyse situationnelle de la division par sexe, nous avons pu mettre en exergue que les statuts sexués sont placés en retrait, au profit de ceux directement en lien avec la pratique ou les individus eux-mêmes. A ce titre, les judokas endossent une pluralité de statuts, qui se voient imbriqués et combinés les uns aux autres. Leur prise en compte dépend de la relation en cours : de ce point de vue, les relations entre judokas dans les clubs sportifs de judo s'articulent à partir d'une hiérarchisation de leurs statuts et des rôles qui y sont associés. / The framework for the practise of judo is a particular one; it stages elements that make the study of gender division in judo sport clubs particularly interesting. Indeed, the socialisation of the body and the integration of non-official codes of the sport aim at de-Gendering the bodies and the judokas, thus promoting the emergence of neutralized gender relations between judokas. From a situational analysis of the gender division, it was then possible to highlight the fact that gendered statuses are set in the background, in favour of those directly related to the practise of the sport or to the individuals themselves. In this respect, judokas take on a plurality of statuses, which are interlinked and combined with each other. Taking them into account depends on the ongoing relation: from this point of view, the relations between judokas in judo sport clubs revolve around a stratification of their statuses and of the roles associated with them.

The objectives of the research study are to review existing subnational credit rating methodologies and their applicability in the South African context, to develop the quantitative parts of credit rating methodologies for two provincial departments (Department of Health and Department of Education) that best predict future payment behaviour, to test the appropriateness of the proposed methodologies and to construct the datasets needed. The literature study includes background information regarding the uniqueness of South Africa’s provinces and credit rating methodologies in general. This is followed by information on subnational credit rating methodologies, including a review of existing subnational credit rating methodologies and an assessment of the applicability of the information provided in the South African context. Lastly, the applicable laws and regulations within the South African regulatory framework are provided. The knowledge gained from the literature study is applied to the data that have been collected to predict the two departments’ future payment behaviour. Linear regression modelling is used to identify the factors that best predict future payment behaviour and to assign weights to the identified factors in a scientific manner. The resulting payment behaviour models can be viewed as the quantitative part of the credit ratings. This is followed by a discussion on further investigations to improve the models. The developed models (both the simple and the advanced models) are tested with regard to prediction accuracies using RAG (Red, Amber or Green) statuses. This is followed by recommendations regarding future model usage that conclude that the department-specific models outperform the generic models in terms of prediction accuracies. / PhD (Risk analysis), North-West University, Potchefstroom Campus, 2015

This dissertation based on a case study explores the acquisition and the guidance of Swedish Sign Language and spoken Swedish over a span of seven years. Interactions between a pair of fraternal twins, one deaf and one hearing, and their Deaf[1] family were video-observed within the home setting. The thesis consists of a frame which provides an overview of the relationship between four studies. These describe and analyze mainly storytime sessions over time. The first article addresses attentional expressions between the participants; the second article studies the mediation of the deaf twin’s first language acquisition; the third article analyses the hearing twins acquisition of parallel bimodal bilingualism; the fourth article concerns second language acquisition, sequential bimodal bilingualism following a cochlear implant (CI). In the frame, theoretical underpinnings such as mediation and language acquisition were compiled, within a sociocultural frame. This synthesis of results provides important information; in the 12- and 13-month sessions simultaneous-tactile-looking was noted in interchanges between the twins and their mother; mediation of bilingualism was scaffolded by the caregivers with the hearing twin by inserting single vocal words or signs into the language base used at that time, a finding that differs from other reported studies; a third finding is the simultaneousness in which the deaf child’s Swedish Sign Language skill worked as a cultural tool, to build a second and spoken language. The findings over time revealed actions that included all the family members. Irrespective of the number of modes and varied types of communication with more than one child, mediation included following-in the child’s initiation, intersubjective meaningfulness and encouragement. In accordance with previous research, these factors seem to promote the acquisition of languages. In conclusion, these findings should also prove useful in the more general educational field. [1] Deaf with a capital ‘D’ is commonly used for cultural affiliation whereas lower case ‘d’, as in deaf, refers to audiological status (Monaghan, Schmaling, Nakamura &amp; Turner, 2003). / <p>Disputationen tolkas till svensk teckenspråk, hörselslinga finns.</p><p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Submitted.

L'ancienne cité maya d'Ucanal se situe à la frontière des grandes capitales et de leurs influences stylistiques pendant la majeure partie de son histoire. De plus, sa localisation sur la rivière Mopan en fait un lieu décisif pour les réseaux d'échanges puisqu'elle relie la mer des Caraïbes au golfe du Mexique. A ce titre, la ville fut convoitée par les grands centres afin de maîtriser les grands axes de communication. Cependant, ces centres n'ont jamais été assez forts pour contrôler complètement la ville d’Ucanal. Cette étude examine ces relations politiques et sociales et leurs changements du point de vue des céramiques d'Ucanal durant la période du Classique Récent (environ 600-810 DNÈ) au Classique Terminal (environ 810-950/1000 DNÈ). Nous avons établi un nouveau protocole méthodologique pour l'analyse chimique des pâtes céramiques à l'aide d’un instrument portable de Fluorescence par Rayons X (pXRF) et comparé les résultats sur les mêmes échantillons à l'aide de l’Analyse Instrumentale par Activation Neutronique (INAA), une méthode plus conventionnelle et plus précise pour les études de provenance chimique. Les résultats de ces comparaisons révèlent que le pXRF pourrait fournir des désignations de provenance préliminaires pour identifier les céramiques locales et non locales (article 1). Une analyse de la répartition des céramiques décorées et importées sur le site d'Ucanal comparant les maisonnées d'élite, de statut intermédiaire et non élite, a indiqué que les maisonnées de statut intermédiaire ont obtenu un accès croissant aux céramiques fines et importées durant le Classique Récent et le Classique Terminal, et que cette dernière était une période de grande mobilité sociale (article 2). À son tour, une analyse du point de vue des communautés de pratique des céramiques moulées de la période du Classique Terminal a révélé qu'Ucanal et sa région se trouvaient à un noeud important des réseaux de production et d'échange de céramique, ce qui a aidé à créer un paysage politique décentralisé mais fortement interconnecté (article 3). / The ancient Maya city of Ucanal sat at the frontier of larger political capitals and their stylistic influences throughout most of its history. Moreover, its localization alongside the Mopan River placed it in a decisive location for exchange networks between the Caribbean Sea and the Gulf of Mexico. As such, the city was coveted by major centers in their attempted control of this major communication axis. However, these centers were never strong enough to completely control the city of Ucanal. This research project examines these social and political relationships from the perspective of Late Classic (ca. 600-810 CE) and Terminal Classic (ca. 810-950/1000 CE) period ceramics from Ucanal. It establishes a new methodological protocol for the chemical analysis of ceramics using a portable X-ray fluorescence instrument (pXRF) and comparing the same samples with Instrumental Neutron activation Analysis (INAA), a more established and precise chemical analysis method. The results indicate that pXRF analyses can provide preliminary provenience identifications of local and non-local ceramics (article 1). A distribution analysis of decorated and imported ceramics from Ucanal that compares elite, middle-status, and non-elite household contexts reveals that middle-status households had increasing access to decorated and imported ceramics between the Late Classic and Terminal Classic periods, and that the latter was a period of substantial social mobility (article 2). In turn, an analysis of molded Terminal Classic ceramics from the theoretical perspective of communities of practice demonstrates that Ucanal and its surrounding region were situated at an important nexus of ceramic production and exchange and helped forge a decentralized but highly interconnected political landscape (article 3).
