AFRIKAANS: In hierdie navorsing is deur aksienavorsing ondersoek ingestel na strategieë wat vir opvoeders bruikbaar is in die hantering van leerders met emosionele en gedragsbehoeftes binne die opset van insluitende onderwys. Leerders in Suid-Afrikaanse skole en klaskamers openbaar ʼn wye verskeidenheid emosionele en gedragsbehoeftes, en hierdie behoeftes word as een van die vernaamste knelpunte deur alle belanghebbendes in die land se onderwys uitgesonder. Anders as in die verlede word daar nou van opvoeders verwag om die primêre hulpverleners te wees van leerders met behoeftes in die konteks van die insluitende klaskamer. In die lig hiervan benodig opvoeders bemagtiging om die leerders te hanteer deur ’n verskeidenheid strategieë te kan gebruik. Die navorsing het deur verskeie fases verloop waar die aanvanklike behoeftes van die opvoeders bepaal is, asook die stand van sake voor die intervensie. Op grond hiervan is ʼn implementeringsprogram saamgestel wat gefokus het op die ontwikkeling van strategieë vir opvoeders van die twee skole, die toepassing daarvan in hul klasse/skool en die effek wat dit op die klasse/skool gehad het. Die implementering is op verskeie sistemiese vlakke gemoniteer – deur die opvoeders in hul eie klasse, maar ook deur eksterne waarnemers en die navorser. Gedurende die fases is die intervensie voortdurend aangepas namate nuwe behoeftes bekend geraak het. Die deelnemers het ook insette gelewer ten opsigte van strategieë en hoe dit aangepas kon word. Nuwe gemeenskaplike kennis van strategieë het tydens die intervensie ontstaan. Na afloop van die program het opvoeders die strategieë vir die hantering van leerders met emosionele en gedragsbehoeftes kwantitatief beoordeel, op grond van die bruikbaarheid daarvan in die skool- en klasopset. Uit my bevindinge het dit geblyk dat opvoeders bemagtiging benodig om met leerders met emosionele en gedragsbehoeftes te werk. Die indiensopleidings-program waaraan 47 opvoeders van twee skole deelgeneem het, het daartoe bygedra dat die opvoeders se ingesteldheid teenoor leerders verander het. Na die opleiding was hulle bekend met meer strategieë om leerdergedrag te hanteer en het ‘n gevoel van sukses beleef in die klas, wat bygedra het tot ‘n positiewe belewenis van die klassituasie. Van die strategieë wat as die bruikbaarste beoordeel is, het gehandel oor klaskamerpraktyke en strategieë om taakgerigtheid te bevorder. Ander strategieë het aspekte rondom skoolbestuur en ondersteuning aan ouers ingesluit. Enkele opvoeders het ook meer gevorderde strategieë, soos kognitiewe en gedragstegnieke gebruik. Opvoeders het positiewe reaksie aangemeld van leerders waar die strategieë toegepas is. Hierdie studie is deur ‘n proses van aksienavorsing uitgevoer en kwalitatiewe en kwantitatiewe navorsingsmetodes is gebruik. Die resultate is van toepassing binne hierdie bepaalde konteks. Volgens die navorser kan hierdie opleidingsprogram aangepas word om aan die behoefte vir indiensopleiding vir opvoeders te voorsien. Opleiding kan moontlik fokus op ʼn kleiner aantal strategieë wat deeglik ingeoefen en vasgelê kan word. Dit is verkieslik dat al die personeel van ‘n skool, insluitend die skoolbestuurspan, aan die opleiding moet deelneem om dit ‘n skoolontwikkelingsprojek te maak. Deur twee skole op verskillende vlakke van implementering saam op te lei, kan opvoeders mekaar stimuleer en kan die toepassing van idees bevorder word. ENGLISH: Learners who exhibit emotional and behavioural needs (e.g. ADHD and depression conduct disorder) seem to present a major challenge for educators in the inclusive mainstream class and educators feel that they are not adequately prepared and trained for these challenges. Action research was chosen as research method. The purpose of this research was to useful strategies which educators could implement in supporting and managing these learners, in the inclusive classroom environment. Learners with emotional and behavioural needs exhibit a wide variety of behaviours at school. In the inclusive education environment educators are expected to be the primary supporters of learners with needs. Although this expectation exists, up till now educators have received little or no training on how to support learners with needs. The research process conducted in this study followed different phases. Firstly, a needs analysis was conducted to determine the current state of affairs, the needs of educators, and strategies currently in use. Information that became evident through the needs analysis and literature research prescribed the format and aspects to be included in the initial intervention programme. During the execution of this programme, current strategies were adapted and new ones developed. Needs that came to the fore during the implementation were recognised and incorporated. The implementation was monitored on different levels, for example by teachers who implemented the strategies in their classrooms and provided feedback, by the researcher, and also by external observers. The focus was not only on the strategies, but also on processes. Changes that were observed in the different systems were assessed. During the final step of the implementation phase, educators, based on their practical experience, were required to rate the usefulness of all the different strategies that were either part of the initial presentation or were generated during the course of implementation. The qualitative as well as quantitative findings indicated that the educators became more capable of supporting these learners and implemented a wide variety of strategies. Classroom management strategies and strategies to support task behaviour were found to be the most helpful. Educators also gained more than merely knowledge. Changes in the relationship between educators and these learners were noticeable and they became aware of feelings of personal achievement and competency. Changes also occurred at other systemic levels, such as in the learners, the school, the community and even in the broader education system. This study was undertaken on a small group of educators in a particular context. Whilst the findings cannot be generalised, it is suggested that this programme may also be beneficial for educators to support learners with emotional and behavioural needs in other environments. / Thesis (DPhil)--University of Pretoria, 2010. / Psychology / unrestricted

This research deals with organisation culture in the Chemical Industry, with specific reference to the culture in Gas Production. In the literature survey, the concept 'organisation culture' is studied theoretically from the perspective of Burke and Litwin. Theoretically, differences may occur between the current and desired organisation culture, between divisions and between levels of authority. The conclusion is drawn that culture change involves the whole organisation. In the empirical investigation, the Organisation Culture Index is applied to 36 employees at management level and 138 at employee level. The empirical findings show that there are significant differences. The empirical findings therefore support the theoretical findings that a single culture does not always exist in an organisation. This research also confirms that the culture in this organisation may not be appropriate for the present era. / Hierdie navorsing ondersoek organisasiekultuur in die Chemiese Bedryf, met spesifieke verwysing na die kultuur in Gasproduksie.

INTRODUCTION AND AIM - Cardiovascular disease is globally a major risk factor for morbidity and mortality. It is caused by various factors, one of which is an abnormal haemostatic process. Fibrinogen is a haemostatic factor that is considered to be an independent risk factor for cardiovascular disease. Elevated fibrinogen can be caused by environmental and genetic factors which increase the risk of the occurrence of thrombosis. The fibrinogen y' chain, which is one of the three chains of fibrinogen, has two different variants, the yA and y’. The presence of the fibrinogen y’ chain has been associated with thrombotic disorders. Many studies have investigated the fibrinogen variables in Caucasian individuals, but only a few such studies have been conducted on non-Caucasian individuals. The genetic diversity of ethnic groups differs and could cause differences in the fibrinogen variables between these groups. Fibrinogen is known to increase with age; therefore to explain changes over time in fibrinogen concentrations it was also important to investigate whether genetic determinants and possible gene–environment interactions influenced fibrinogen over time. In this study the main aim was to determine the change in the fibrinogen variables over a five-year period within a black South African cohort subdivided according to genotypes associated with fibrinogen variables, and to determine whether the observed changes were modulated by environmental factors. PARTICIPANTS AND METHODS - Data [baseline (n=2010) and follow-up (n=1288)] were collected in the Prospective Urban and Rural Epidemiology (PURE) study during 2005 and 2010 from apparently healthy black men and women aged between 35 and 65 years and residing in rural or urban settlements. Experimental methods included analysis of fibrinogen and fibrinogen y’ concentrations, single nucleotide polymorphisms (SNPs) and determination of environmental factors associated with the fibrinogen variables. RESULTS - The fibrinogen variables increased significantly from 2005 to 2010 in both the rural and urban participants, as well as in both men and women. The major environmental factors that affected the fibrinogen variables were C-reactive protein (CRP), interleukin-6 (IL-6), body mass index (BMI), glycated haemoglobin (HbA1c), age, blood lipids, human immunodeficiency virus (HIV) and tobacco use. Fibrinogen increased consistently from 2005 to 2010 in the respective genotypes of all SNPs analysed, except in the FGG 9340 T>C homozygous mutant carriers. Fibrinogen y’ also increased in general in most genotypes from 2005 to 2010, except in the FGG 10034 C>T mutant allele carriers, where a decrease was observed. It was determined that CRP was the only environmental factor that influenced the change in fibrinogen over time and that FGG 10034 C>T was the only SNP that influenced the change in fibrinogen y’ over the five years. Four gene–environment interactions also influenced fibrinogen on a cross-sectional level, i.e. FGA 2224 G>A with age, FGB Arg448Lys with HIV status, FGB 1643 C>T with urbanisation and FGB 1038 G>A with HbA1c. Only the FGG 9340 T>C with HbA1c interaction was found to predict change in fibrinogen concentrations over the five years. CONCLUSION - Both environmental and genetic factors significantly influenced the fibrinogen variables cross-sectionally as well as prospectively. It was clear that the influence of the environmental factors was mediated by genetic polymorphisms and vice versa, as can be seen by the gene–environment interactions found in this study. An important finding of this study was that the interaction of HbA1c with two SNPs on fibrinogen variables may explain the known inconsistent relationship found between fibrinogen concentrations and diabetes. / MSc (Dietetics), North-West University, Potchefstroom Campus, 2014

Summaries in English and Afrikaans / Hierdie studie is onderneem om die effek van leierskap op verandering in 'n nie-winsgewende organisasie te bepaal. 'n Literatuur- en 'n empiriese studie is onderneem. Literatuur beklemtoon dat verandering 'n realiteit in 'n organisasie is, 'n veranderingsagent die proses meet dryf en dat die transformasieleierskapstyl die gewenste styl vir veranderingsbestuur is. Navorsing toon dat verandering vanwee eksterne invloede wel voorkom. Verwarring ten opsigte van wie die rol en verantwoordelikheid as veranderingsagent moet vertolk kom egter in die navorsing na vore. Die wyse en frekwensie waarop kommunikasie ten opsigte van verandering plaasgevind het, word oor die algemeen positief deur die respondente ervaar, maar respondente toon egter ook positiewe en negatiewe gedragsreaksies aan ten opsigte van verandering. Respondente toon dat die transformasieleierskapstyl met leierskapsgedrag/-kenmerke wat verband hou met integriteit toeganklikheid en objektiwiteit hul tot deelname aan verandering motiveer. Navorsing toon ook dat leierskapspotensiaal en die behoefte aan leierskapsontwikkeling by respondente teenwoordig is. Navorsing het bevestig dat leierskap 'n effek op verandering in 'n nie-winsgewende organisasie het. / This research aims to establish whether leadership has an effect on change in a not-for-profit organisation. A literature and empirical study were conducted. Literature indicated that change in organisations is a reality and that organisations need to appoint change agents in order to facilitate the change process. Research has shown that change in noHor-profit organisation was caused by external influences and indicated that confusion exists as to whom the role and responsibility of change agent belongs to. Respondents indicated that they were generally positive about the frequency and way in which change was communicated but they indicated both positive and negative behavioral reactions to change. The transformational leadership style is highlighted as the best leadership style to manage change. The transformational leadership style with leadership behavior such as integrity, approachability and objectivity motivates respondents to participate in the change process. Research also indicated that respondents have leadership potential and have a need for leadership development. This study confirmed that leadership has an effect on change in a not-for-profit organisation.

The Student RAG Community Service (SRCS), a unique non-governmental organisation (NGO) of the Potchefstroom Campus of the North-West University, aims to support and to enable other NGOs to function independently. For this reason, the communication between the SRCS and these NGOs is viewed from the sub discipline of development communication, with the participative approach currently being perceived as the normative approach to communication for development. Communication between the SRCS and representatives of the NGOs should therefore conform to the principles of the participative approach to development communication to contribute to empowerment and development. The principles of the participative approach that was identified as relevant to this study are participation, dialogue, cultural sensitivity, to enable the community to be self-reliant and community development. This study is qualitative in nature and the research methods used to gather information about the nature of communication between the SRCS and the representatives of the projects are qualitative content analysis, partially structured interviews and observer–participant reporting. Although this study has focused only on early child development projects, the nature of these projects and their communication varied to a large extent. The overall conclusion of this study is that there are gaps in the participative communication between the SRCS and the representatives of all the researched projects. The type of communication between the SRCS and early childhood development projects did not conform to the principles of cultural sensitivity, community development and the enablement of the community to be self-reliant. These gaps are attributed in part to the present documentation of the SRCS (2010 annual report, portfolio descriptions, transfer reports and minutes of 2010’s and 2011’s meetings) as well as the fact that this NGO’s training guidelines do not emphasise the importance of participatory principles, and do not offer sufficient training in the implementation of these principles to its various members. Although the results indicate that the communication between the SRCS and the representatives of the projects presently does not conform to the principles of participative communication, the organisation is committed to addressing these gaps in future. / Thesis (MA (Communication Studies))--North-West University, Potchefstroom Campus, 2013.
