Background: Iron deficiency (ID) is the most prevalent nutritional deficiency in the world. In children, both inadequate iron and fatty acid (FA) status have been found to have an effect on cognitive and behavioural function, including physical activity behaviour and attention deficit hyperactivity disorder (ADHD)–related behaviour. Aim: To investigate the effects of supplementation with iron and omega–3 fatty acids (n–3 FAs), alone and in combination, on spontaneous motor activity and ADHD–related behaviour in iron deficient primary school children in KwaZulu–Natal. An additional aim was to evaluate the use of the Actical accelerometer as a tool to assess physical activity behaviour. Methods: The study design was a 2x2 factorial, randomized, double–blind and placebo–controlled trial. Iron deficient school children aged six to ten years with or without mild anaemia were included in the study (n = 321). Subjects were randomly assigned to receive one of the following supplement combinations: (1) 420mg docosahexaenoic acid (DHA)/80 mg eicosapentaenoic acid (EPA) + 50mg of iron as ferrous sulphate (Fe); (2) 420mg DHA/80mg EPA + placebo; (3) 50mg of Fe + placebo; (4) placebo + placebo. Supplements were provided four times a week for a duration of 8.5 months (excluding school holidays). Physical activity of a subgroup of subjects (n=98) was recorded on four random school days at baseline, midpoint and endpoint (12 days in total) during three different time periods namely class time 1 (08h00-10h30), break time (10h30–11h00) and class time 2 (11h00–12h00). Classroom behaviour of study subjects was assessed by teachers at baseline and endpoint using the Conners’ Teacher Rating Scale–Revised: Short Forms (CTRS). Iron status indicators and red blood cell (RBC) FA composition were measured at baseline and endpoint. Treatment effects were assessed for activity and CTRS scores. Furthermore, the relationship between activity, CTRS scores and iron/FA status indicators was determined using bivariate correlation and multivariate linear regression analysis. Results: Overall activity of all subjects varied over time from baseline and midpoint to endpoint. A significant cycle x age interaction (P = 0.005) as well as a significant cycle x time period x gender interaction (P = 0.036) was observed on overall activity. There were no significant interactions of cycle or time period with treatment. However, there was a significant main effect of DHA/EPA supplementation for lower class time 1 activity at endpoint (P = 0.014). Biological markers indicating better or poorer iron status were positively and negatively associated with activity at break time, respectively. Subjects in the group receiving both iron and DHA/EPA supplements showed a significant improvement from baseline to endpoint on the cognitive problems/inattention subscale (P = 0.005) of the CTRS. Hyperactivity scores increased iv significantly from baseline to endpoint in all groups (P = 0.006). DHA (r = –.203; P = 0.040) and EPA (r = –.199; P = 0.044) content of RBC were negatively associated with activity at class time 1. No significant associations were observed between activity and CTRS scores at baseline. At endpoint, class time 1 activity was positively associated with all CTRS subscale scores except for the cognitive problems subscale, which only bordered significance (correlation, P = 0.051; regression, P = 0.073). Conclusions: These findings suggest that n–3 FA supplementation may have an influence on ADHD–related behaviour during class time. During school break time when subjects were allowed to move around freely, iron status was positively associated with spontaneous motor activity. Furthermore, the accelerometer might be a useful complimentary tool for assessing both classroom and break time activity behaviour in school children. / Thesis (M.Sc.

This research was aimed at the lack of knowledge with regards to the nature, causes and disruptive behavioural patterns as a consequence of adolescents with self-destructive behaviour, and the way in which it limits effective intervention. A lack of research and literature, especially within the South-African context, contributes to this lack of knowledge. As a result, therapists tend to distance themselves, misinterpret and even ignore this behaviour. Some therapists, especially social workers, fear this behaviour, are frustrated by and even disapprove of clients who present self-destructive behaviour. The goal of this study was to address the lack of knowledge with regards to self-destructive behaviour in adolescents within a social work perspective. A knowledge framework has been developed by investigating the nature, causes and disruptive behavioural problems as a consequence in adolescents, which will serve as a reference for therapists. In order to reach the required goal, a number of objectives were set. This included the development of a knowledge framework by means of a literature study as well as consultation with experts in the field of self-destructive behaviour in adolescents. An empirical study was undertaken during which a collective case study was utilised as strategy for the gathering of data. During these interviews, the researcher tried to gather information about the nature, causes and disruptive behavioural problems as a consequence in adolescents who demonstrate with this behaviour. Three participants took part and the three case studies were compared. Applied research was used as the researcher aimed to explore the problem (namely adolescents with self-destructive behaviour) scientifically in order to develop a knowledge framework. The researcher used a qualitative research approach and in this way, qualitative empirical information was gathered. This study embraced research of a relatively unknown research field. This led to the researcher utilising an exploratory study design in order to investigate a research question, which comprises of limited information. The research question that was formulated for the means of this research was: What are the nature, causes and disruptive behavioural problems as a consequence of self-destructive behaviour in adolescents? Empirical data was gathered by means of case studies and led to the development of a research framework which contains the following information: 1. The nature of self-destructive behaviour 2. The causes of self-destructive behaviour 3. The link between self-destructive behaviour and suicide 4. The “therapeutic value” of self-destructive behaviour Thus, the research indicated that adolescent self-destructive behaviour is a common problem which therapists must face without appropriate knowledge and skills. Therefore, it is of outmost importance that social workers be trained accordingly in order to handle the problem of self-destructive behaviour in a constructive manner. / Dissertation (MSD (Play Therapy))--University of Pretoria, 2006. / Social Work / unrestricted

Education is essential in providing future human capital that is much needed to build a sustainable, competitive economy. However, the importance of a quality education is often underestimated. In order to enhance working conditions of educators, it seems essential to investigate the role of the positive psychology paradigm by means of developing teachers’ areas of deficiencies and capitalising on their strengths in order for them to reach their full potential and flourish. The current study aimed to adapt and validate the recently developed Strengths Use and Deficit Improvement Questionnaire (SUDIQ) in an attempt to make it suitable for educators. The general objective of this research study was to establish the psychometric properties of the SUDIQ by means of confirmatory factor analysis (CFA), convergent, discriminant and empirical validity. A cross-sectional field survey design and a convenience sample of educators from several educational institutions in the Gauteng Province (N = 502) was utilised to gather the data. CFA was used to test the factorial validity of the adapted SUDIQ scale. In order to prove convergent and discriminant validity, the relationships between the SUDIQ dimensions and similar theoretical constructs (job resources, strengths use, psychological capital, proactive behaviour and person-job fit) as well as constructs postulated to be unrelated to the SUDIQ dimensions (age and education) were determined. Finally, the relationship between the SUDIQ dimensions with vigour, dedication, emotional exhaustion and depersonalisation was determined by using multiple regression analysis. The results confirmed that the SUDIQ comprised a four-factor structure. These four factors were perceived organisational support for strengths use, perceived organisational support for deficit improvement, proactive behaviour towards strengths use and proactive behaviour towards deficits improvement. These dimensions were positively related to the scales such as the strengths use scale, autonomy, supervisor and colleague support, psychological capital, proactive behaviour, and person-job fit. Anticipated perceived organisational support for deficit improvement and proactive behaviour towards strengths use and proactive behaviour towards deficit improvement were unrelated to age. The scales were also relatively weakly related to education. Furthermore, the results revealed that perceived organisational support for strengths use, proactive behaviour towards strengths use and proactive behaviour towards deficit improvement were significant predictors of both vigour and dedication. However, it was found that the only SUDIQ dimension that predicted emotional exhaustion and depersonalisation was proactive behaviour toward strengths use. Recommendations were made to be applied in practice, as well as for future research. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2014

Problem statement Due to HIV and AIDS impacting on communities, devastating consequences have been predicted. The number of orphans and vulnerable children (OVC) in need of care is escalating, causing social workers’ caseloads to become unmanageable. These OVC who lost their parents through death are suffering multiple losses due to being orphaned. The material, protection and affection needs have to be addressed in a holistic, eco-systematic, multidisciplinary team approach. In practice social workers tend to focus mainly on the material and protection needs of OVC due to high caseloads and staff turnover, neglecting their affection needs. Social workers need to work with foster parents and children in identifying potential risk factors that could lead to risk behaviour in foster children who have lost their parents through death. The researcher designed an assessment tool that could enable social workers in practice to do an effective risk assessment of OVC in foster care. Intervention could be planned accordingly by setting goals to address risk factors timeously in an attempt to prevent future problem behaviour in OVC placed in foster care. Aim To develop an assessment tool for social workers to identify risk behaviour in foster children who have experienced multiple losses such as the loss of one or both parents. Method A mixed methods design was used, specifically the sequential and explanatory design which involved collecting and analysing both qualitative and quantitative data. These obtained data were then connected and integrated. Results It was proved that a Risk assessment tool helped social workers to identify risk factors in a team effort between social workers, foster parents and children. Meeting the psychosocial needs of OVC placed in foster care more effectively is important in order to prevent the development of negative behaviour. / PhD (Social Work), North-West University, Potchefstroom Campus, 2015

The widening of access to Higher Education (HE) with a concomitant call for more accountability in the HE sector locally and globally, has altered the former elitist status of the university and impacted the professional standing, autonomy, and working conditions of lecturers negatively. Lecturers are increasingly held to account for providing quality teaching and delivering employable graduates. Yet their work environment has been characterised by poor support, dwindling resources, lack of recognition and reward for teaching efforts and excellence, and absence of legal protection when failing to fulfil the undefined yet high accountability expectations in their teaching-related work. This state of affairs has had an inevitable influence on lecturers’ perceived security in their labour environment. The overarching purpose of this study was therefore to generate guidelines to improve the existing juridical foundation for accountability of South African (SA) HE lecturers with a view to enhance their security in their employment context. In order to assist in the fulfilment of this central purpose, the study aimed to develop understanding of how lecturers perceive their accountability and security in light of diverse teaching-related responsibilities and vagueness in terms of expected conduct; and the protection (or lack of protection) of their rights and professional status. An international perspective on these issues was imperative to shed some light on how regulation elsewhere could improve practices in the SA context. While SA lecturers are equally entitled to all the rights stipulated in the Bill of Rights, they are also subject to and accountable for upholding the provisions of the SA Constitution and derived labour legislation relevant within the HE environment. The founding values of the Constitution, namely equality, human dignity and the protection of human rights and related freedoms, form not only the basic standard for measuring lecturer conduct, but also the legal basis for challenging policy, system or conduct that might threaten constitutional or labour rights. Yet, despite the existing juridical foundation for the regulation of accountability and rights protection of SA lecturers, comprising the SA Constitution, general labour and HE legislation, there is an absence of HE-specific teaching-related accountability regulation, resulting in lecturer insecurity regarding expected conduct, professional recognition and support, and accountability expectations in their teaching-related work. In comparison, a number of Australian legal imperatives, including the Commonwealth of Australia Learning and Teaching Council’s standard for quality teaching with corresponding quality indicators, provide for more clearly defined teaching-related accountability regulation. In addition, the Mission Based Compacts, the Threshold Standards, and the national Modern Award for the Higher Education Industry, afford Australian lecturers the protection of HE-specific rights relevant to enhance security in their unique work environment. These legal imperatives proved to be significant for informing the improved juridical foundation for lecturer teaching-related accountability in the SA context to enhance the security of the SA lecturer. With a focus on the development of in-depth understanding of the phenomena of lecturer accountability and security via the perspectives and interpretations of lecturers themselves, the empirical study was grounded in an inductive qualitative methodology from an interpretive-phenomenological perspective. To ensure richness of descriptive data, lecturers actively involved in undergraduate teaching at three different local, and one Australian university, were purposively selected to participate in semi-structured individual and focus group interviews. The analysis and interpretation of the interview data included a comparative component to explore perceptions of lecturer accountability regulation and security protection in an Australian context with a view to identify inadequate legal provisioning for these phenomena in the SA HE environment. From the data analysis and interpretation, seven meaningful themes were identified, associated with either lecturer accountability or lecturer security. The findings offered not only a clear delineation of internal and external lecturer teaching-related accountability, but also a comprehensive definition of lecturer professional security that was found wanting in all legal sources and other literature studied for this thesis. Moreover, in realisation of the primary aim of this study, twelve significant guidelines are presented to establish an improved juridical foundation for lecturer accountability that will enhance lecturer security in the SA Higher Education context. Amongst these are: the development of a clear delineation of teaching-related roles and responsibilities articulated for different academic post levels; the establishment of a professional HE teaching-oriented career path affording professional recognition via a professional body for lecturers, and requiring continuous professional teaching development; and the development of minimum conditions of employment unique to the work of the HE lecturer. / PhD (Education Law), North-West University, Potchefstroom Campus, 2015
