  • Description: Digital audio networks are becoming the preferred solution for the interconnection of professional audio devices. Prominent amongst their advantages are: reduced noise interference, signal multiplexing, and a reduction in the number of cables connecting networked devices. In the context of professional audio, digital networks have been used to connect devices including: mixers, effects units, preamplifiers, breakout boxes, computers, monitoring controllers, and synthesizers. Such networks are governed by protocols that define the connection management rocedures, and device synchronization processes of devices that conform to the protocols. A wide range of digital audio network control protocols exist, each defining specific hardware requirements of devices that conform to them. Device parameter control is achieved by sending a protocol message that indicates the target parameter, and the action that should be performed on the parameter. Typically, a device will conform to only one protocol. By implication, only devices that conform to a specific protocol can communicate with each other, and only a controller that conforms to the protocol can control such devices. This results in the isolation of devices that conform to disparate protocols, since devices of different protocols cannot communicate with each other. This is currently a challenge in the professional music industry, particularly where digital networks are used for audio device control. This investigation seeks to resolve the issue of interoperability between professional audio devices that conform to different digital audio network protocols. This thesis proposes the use of a proxy that allows for the translation of protocol messages, as a solution to the interoperability problem. The proxy abstracts devices of one protocol in terms of another, hence allowing all the networked devices to appear as conforming to the same protocol. The proxy receives messages on behalf of the abstracted device, and then fulfills them in accordance with the protocol that the abstracted device conforms to. Any number of protocol devices can be abstracted within such a proxy. This has the added advantage of allowing a common controller to control devices that conform to the different protocols.

  • Description: Psychobiographies use psychological theory as a paradigm within which to re-awaken an individual’s life story. The psychobiographical approach historically tended to be neglected within the South African context. The aim of the current study was to explore and describe the life of Ralph John Rabie through the use of psychobiography. Ralph John Rabie (1960 – 2002) was a South African Afrikaans singer-songwriter, journalist and playwright, also known as Johannes Kerkorrel. He challenged the cultural system and the government and was arguably the most prominent member of the Alternative Afrikaans Movement until his suicide on 12 November 2002. To some he betrayed the identity of post-apartheid Afrikanerdom and to others he became an icon in the homosexual community. No existing literature to date has adopted a psychological stance on this controversial South African figure. His own writings and published material by others were utilized to illuminate his life and its many dimensions. Richard C. Schwartz’s Internal Family Systems Model (1995) was used to analyze the multiplicity and inner workings of Rabie’s personality. The influence of external systems is also discussed. The data collection and analysis were conducted according to Yin’s (1994) analytic generalization, which consists of using theoretical guidelines as a framework to select relevant data and develop a matrix as a descriptive framework for organizing and integrating the data. Alexander’s (1988) nine proposed guidelines assisted in the process of data analysis, together with the Internal Family Systems Model (1995). The findings of the study indicate that subpersonalities in different roles could be identified in Rabie’s life as described by Schwartz (1995). The different subpersonalities interacted with each other and assumed roles to protect Rabie. The findings of the study also indicated that these subpersonalities used stories to obtain power and influence within Rabie’s personality structure. The subpersonalities were successful in making Rabie influential and famous within the Afrikaans music industry and they helped Rabie change rigid Afrikaans cultural beliefs that were present within the Apartheid system. The findings further indicate how important it is for subpersonalities to work together and how a fragmented system is difficult to contain.

  • Description: While the value of psychobiographical research continues to be debated, interest in this area is growing on an international basis. From the ever increasing number of studies being conducted in connection with academic institutions in South Africa, the vitality and worthiness of studying lives lived in conjunction with the applicability of psychological theories is showing itself to be an exciting world in which to participate. This particular research study aimed to explore and describe the developmental life stages of Paul Jackson Pollock. Pollock was, and continues to be, a controversial figure in the art world as there is much debate over the artistic merit of his paintings. Unconventional in all that he did, Pollock challenged the art world by moving beyond paintbrush and easel to throwing paint across canvasses laid out on the floor. Around these emerging artworks he would move in a staccato dance, mesmerising those present by the way he made art immediate using his entire body to create the abstract image. Pollock is credited with being the pioneer of abstract expressionism in the United States, and to date his paintings are credited as being among the most expensive ever sold. He struggled with alcoholism and emotional instability throughout his teens and adult life. His alcoholism eventually caused his death at the age of 44 when, while heavily intoxicated, he drove his car into a tree a few metres from his home. No known literature has adopted an exclusively psychological stance when studying the life of this individual. The progression of Pollock’s lifespan development was filtered through Erikson’s (1950) theory of psychosocial stages. Erikson’s (1950) theory takes a holistic, biopsychosocial approach to human development, with an emphasis on ego development. Data was collected from both primary and secondary sources to enhance internal validity, and the data was then analysed according to Miles and Huberman’s 1994 general approach, taking Alexander’s (1990) nine identifiers of salience into necessary consideration. Using this framework, it was found that Jackson Pollock’s development coincides with Erikson’s theoretical psychosocial stage constructs, lending weight to Erikson’s theory. While Pollock’s life paralleled Erikson’s (1950) theory in many ways, the theory failed to provide enough definition with regards to constructs and intrapsychic processes. However, this study has also shown that there is great value and relevance to be found in Erikson’s (1950) theory, even though it was developed over fifty years ago.

  • Description: Organisations or individuals that lend money (banks and micro lenders) or that sell goods on credit (retailers) are classified as credit providers. The debtor enters into a contractual agreement with a credit provider, or creditor, with the obligation to repay the loan amount, fees and interest according to a predetermined schedule. The contractual agreement, also known as a credit agreement, is as a general rule very complex. Legislation protecting debtors in various ways is an international phenomenon. In South Africa, the National Credit Act, Act 34 of 2005 (NCA) was enacted in 2005. The NCA changed the playing field for credit providers participating in the South African consumer credit market to a great extent. Consumer lending is the sleeping giant of the financial sector. The key to successfully unlock this enormous market is the credit provider's ability to accurately assess the creditworthiness of a potential customer during the customer acquisition phase. The creditworthiness of the customer is related to the risk of default, i.e. a debtor's non-payment of debt in terms of the credit agreement. The risk of default is also known as credit risk. Real People Investment Holdings (Pty) Ltd (RPIH) classifies credit risk as the single largest risk the Group is exposed to. They recognise that the intelligent and responsible management of credit risk makes it the Group's largest profit driver. Credit risk scorecards are excellent decision aids during the customer acquisition phase. The characteristics and behaviour of merchants submitting credit applications to RPIH for assessment have a definite impact on the credit risk of the Group. The merchant plays a pivotal role in the debtor-creditor-supplier business model. The merchant influences the customer's sales experience and subsequent level of satisfaction with the transaction. A satisfied customer constitutes a lower level of credit risk for the creditor, in this case RPIH. The research is conducted with a positivistic paradigm. The cross-sectional study approach is used. The merchant is the unit of analysis. A sample of 77 merchants is selected from the population of 244 merchants who submitted credit applications to RPIH during the observation period. Questionnaires are used as the data collection method in this research project. The predictive ability of fourteen merchant related characteristics are demonstrated through this empirical study.

  • Description: Service-oriented architectures (SOA) are being adopted by organisations in order to integrate disparate computational assets. A major hurdle they face is the decision on how to integrate the UI in an SOA. In addition, technological advances have allowed complex applications and complex user interfaces (UIs) to be realised and the increase in accessibility to computers enables a diverse population of users with different characteristics, preferences and needs to use these complex computer applications. Adaptive user interfaces (AUIs) have been proposed as a solution to cater for the differences in user traits by adapting the UI to meet the diverse needs of users. AUIs have, however, traditionally been developed using client/server architectures This research, therefore, set out to investigate how to develop an AUI using a service-oriented architecture (SOA). In order to successfully achieve the goal of this research, literature concerning SOAs was investigated to gain an understanding of SOAs. A literature review of AUIs was also undertaken to gain an understanding of AUIs. A model-based approach was used to develop a model for UI adaptation using knowledge gained in the literature reviews. The model generates different UIs depending on various users‘ inferred level of expertise. The model describes the interaction between AUI services that use design-time documents and run-time user-interaction to adapt the UI. A prototype of the model was implemented and evaluated using an evolution strategy devised to assess different aspects of the research. The evaluation strategy proved the following: The service components of the prototype adhere to SOA design principles; The implementation was effective based on software engineering metrics; and, The implementation was usable and did not negatively affect the performance of users. The successful implementation of the prototype provides evidence that the design of AUIs using SOA is feasible. This dissertation therefore makes a contribution to the development of AUIs using SOAs. The model could be used to provide UI adaptation for business software applications.

  • Description: This study reports on a social-realist analysis of collaborative curriculum development in a journalism and media studies (JMS) department at a South African university. Archer's social-realist meta-theoretical framework is used to theorise about mechanisms that influence collaborative curriculum development within the context of the JMS Department. The thesis examines the cultural, structural and agential conditions that influenced the process of developing a JMS curriculum that aimed to integrate theory and practice. Bernstein's theories of knowledge recontextualisation and disciplinary knowledge structures are used in the analysis. Bernstein argues that knowledge recontextualisation constitutes a site of struggle. This thesis is an examination of the "struggles" for the epistemic-pedagogic device (Maton's elaboration of Bernstein's epistemic device) during the recontextualisation process that aimed to integrate media studies (MS) and media production (MP) in the JMS curriculum. Traditionally academic work has been an individual endeavour. However, given the growing need to work in disciplinary and inter-disciplinary teams, it is imperative to develop knowledge of the mechanisms that influence such practices. This thesis is a contribution to knowledge of collaborative processes at the level of an academic department in a university. It contributes to knowledge of cultural, structural and agential mechanisms that enable or constrain collaborative curriculum development within a particular kind of context. In addition it contributes to knowledge of the nature of leadership that may be necessary to facilitate productive collaborative relationships and practices in such a context. The curriculum development project reported on in this thesis was initiated in 2003; however, data collection for the study was conducted in 2006 when the curriculum for the fourth year (JMS 4) of the Bachelor of Journalism degree was developed. Since the JMS course prepares students to work as journalists or media workers it is necessary for the curriculum and pedagogy to be oriented both towards the academy and towards the media industries. The aim of the JMS degree is to develop students who will be critically reflexive journalists or media workers. As such the course is both theoretical (MS) and practical (MP). One of the findings of this research project is that the integration of MS and MP is a complex project given that the knowledge of the two disciplines is structured differently. MS is concept-dependent and some aspects of it can be applied to journalism and media practice, while MP is practical and thus context-dependent, though underpinned by theory. A further finding is that both the collaborative work and the integration project required different identity shifts from the lecturers in the JMS Department. Some were more able to make the shifts than others. The thesis shows that the knowledge recontextualisation struggles in the curriculum development processes of the Department of JMS centred around, inter alia, the setting of boundaries between the department and the media and journalism industries, between MS and MP and between MS theory and journalism theory. In addition, existing boundaries between MS and MP lecturers had to be traversed. These boundaries were circumscribed by, amongst other things, unequal power relations emanating from the higher status traditionally accorded to theoretical knowledge by universities, the tensions around the nature of journalism education and training and the differential properties and powers of the various lecturers within the department. The existence of a strong regulative discourse was found to be an important unifying mechanism in a tension-ridden context.

  • Description: Several Schiff base ligands, N, N‟-(aryl)benzyaldiimine ligands (R-BEN); N, N‟-(aryl)benzyaldiamine dihydrochloride ligands (R-BENH•2HCl); N, N‟-(aryl)benzyaldiamine ligands (R-BENH); N, N‟-bis(cinnamaldiimine) ligands (R-CA2EN) were synthesized for the investigation of the electronic effect of the substituents at para-position of the Schiff base ligands and their copper complexes. The synthesis of Schiff bases was carried out by reacting a series of para-substituted benzyaldehyde, and para-substituted cinnamaldehyde with ethylenediamine. The imine group of Schiff bases, N, N‟-(aryl)benzyaldiimine ligands and N, N‟-bis(cinnamaldiimine)ligands were reduced to corresponding amines with sodium borohydride in methanol These ligands, N, N‟-(aryl)benzyaldiamine ligands (H-BENH), N, N‟-bis(cinnamaldiimine)ligands (CA2EN) were reacted with copper(II) dihalide and copper(I) monohalide ions respectively to form complexes. The ligands and their complexes were analysed using elemental analyses, FT-IR spectroscopy (mid-IR), UV/vis in aprotic and protic solvents,while mass spectrometry, 1H-NMR and 13C-NMR were used to further analyse the ligands. By using substituent parameters, both the single and dual substituent parameters with the spectroscopic data obtained from the spectroscopic techiques mentioned above, it was hoped to monitor and determine whether the electronic effects (resonance or inductive effcets) was predominantly within the Schiff base ligands and copper complexes. The NMR studies with dual substituent parameters suggest that the effects of the substituents are transimitted through the ligands, via resonance effects and that the phenyl group is nonplanar with the azomethine in N, N‟-(aryl)benzyaldiimine ligands. The presence of an extra double bond in Schiff base {(N, N‟-bis(cinnamaldiimine) ligand)} altered the electron density. The UV/vis studies showed that the symmetry of the N, N‟-bis(4-R-benzyl)-1, 2-diaminoethanedihalidecopper(II) complexes were predominantly tetrahedral for both chloro and bromo complexes. The correlation studies from mid-infrared were beneficial in monitoring the effect experienced by N, N‟-(aryl)benzaldiimine ligands, the studies suggest that the inductive effect is more pronounced at the C=N.

  • Description: The strategy of the organisation and its entrepreneur’s expectations of the organisation should be aligned in order to create an environment in which all entrepreneurs are motivated and work towards common goals. Furthermore, the entrepreneur’s life stages and personal life plans should be synchronised with the needs of the organisation to achieve the goals. As organisations pass through different stages of growth; they require different resources to assist in progression to next stages. As with organisations and their growth phases; entrepreneurs also undergo growth stages in many different areas of their lives. Entrepreneurs being individuals each have their own set of characteristics in terms of personality, leadership style, entrepreneurship type, skills, life stage and career stages. The challenge of an organisation is to create a strategy that best matches the expectations of all the entrepreneurs and members. The resources of the organisation need to be aligned in order to achieve the common strategy. The problem is as to how the organisation makes use of its leaders and entrepreneurs to achieve strategy; and how does it deal with inconsistencies in goals of entrepreneurs and shortfalls of specific skills or resources that it will require to sustain or grow the organisation?

  • Description: There has been only limited scholarly analysis of Malawi’s foreign policy since its independence in 1964 with key texts focusing primarily on the early years of the new state. Perhaps due to its relatively small stature – economically, politically and militarily – in the region, very little attention has been paid to the factors informing Malawi’s apparently uncritical foreign policy response to the Zimbabwe crisis since it began in the late 1990s. This thesis addresses this deficit by locating its understanding of Malawi’s contemporary foreign policy towards Zimbabwe in the broader historical and contemporary context of bilateral relations between the two states and the multilateral forum of SADCC and SADC. It is argued that the Malawi’s long-standing quest for socio-economic development has forced it to manoeuvre a pragmatic but sometimes contentious foreign policy path. This was also evident until the end of the Cold War and the concomitant demise of apartheid in South Africa in the early 1990s. Malawi forged deliberate diplomatic and economic relations with the region’s white-ruled Zimbabwe (then Southern Rhodesia) and South Africa in pursuit of its national economic interests while the majority of southern African states collectively sought the liberation of the region by facilitating the independence of Zimbabwe and countering South Africa’s apartheid and regional destabilization policies. In the contemporary era, there has been a convergence of foreign policy ambitions in the region and Malawi now coordinates its regional foreign policy within the framework of SADC, which itself prioritizes the attainment of socio-economic development. However, to understand Malawi’s response to the Zimbabwe crisis only in the context of SADC’s “quiet diplomacy” mediation efforts obscures important historically rooted socioeconomic and political factors that have informed relations between Malawi and Zimbabwe and which cannot, it is argued, be ignored if a holistic understanding of Malawi’s position is to be sought. This study argues that the nature of historical ties between Malawi and Zimbabwe and the role of Malawi’s leaders in driving its long-standing quest for socioeconomic development have not only informed its overall foreign policy behaviour in the region but underpin its contemporary relations with Zimbabwe.

  • Description: This study investigates parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Eastern Cape Province. The research study was conducted in three high schools in Zwelitsha Township. These schools are Nompendulo Senior Secondary, Thembalabantu High School and Xolani Senior Secondary School. Questionnaires were designed and distributed to the principals, educators and parents whose children are learners in these schools. The interview questions were designed and distributed to parents whose children are learners in these selected schools, educators and school principals and members of the school governing body from each school. Respondents were asked about the levels of parental involvement in their schools, parents’ awareness of school governance and the relationship between schools and communities. However, the objectives of the study were to: Assess parental involvement in school governance in selected high schools in Zwelitsha, King Williams Town District in the Province of the Eastern Cape; To determine the nature and extent of parental participation in school academic activities; To examine the role of parents in the school governing body; To determine measures that can be taken to encourage the participation of parents in school governance These objectives have been achieved by providing empirical evidences which shows that the levels of parental involvement in the previously disadvantaged high schools are very low. This is related to the parents’ level of education. Parents who are literate are more involved than those are illiterate. This research also reveals that high v. levels of working parents contributes to the low levels of parental involvement in school governance. Most parents in this area know nothing about school governance and those that are aware are not keen to be involved. The class structure of the society has an influence in the participation of parents in school governance. Parents’ meetings that are held on Sunday afternoon are a challenge to parents that come from the villages outside Zwelitsha because of the scarcity of transport on this day. and these situations discourage them from being actively involved in their children’s education. The study provides the factors that cause non-involvement of parents in school governance. Subsequently, the following strategies for participation of parents in school governance were given:  Capacitating of parents Establishment of teacher-parent collegiality  Recognition of cultural capital Establishment of parent organisations  Utilisation of non-governmental organisations Establishment of centres of learning. This study also indicates the following strategies that may assist to enhance the parental involvement in school governance: Parents engagement and empowerment Co-operation between schools and parents Collaboration with other community, private and other public institutions Invitation of complaints and welcoming of criticism. In conclusion, the findings provide clear indication that the participation of parents in school governance is low. Recommendations that could assist the schools to encourage and to enhance parents to participate in school governance are given.

  • Description: Rural-urban migration appears to be an ongoing process in South Africa. This is attributed to various reasons. In itself, the process contributes towards an ongoing demand for services such as housing, water, sanitation and transportation systems. Rural – urban migration plays a key role in urbanization. The living conditions in rural areas appear to be the main contributing factors towards rural-urban migration. This indicates that the challenges facing rural communities include the creation of conducive environments within those communities. Hence, the issue of rural-urban migration should be addressed from the spatial and socio – economic perspectives. In an attempt to address human settlements needs, South Africa has a policy framework which supports the right to housing as it has been accorded to South African citizens by their Constitution. The objective is to ensure that there is adequate housing for South Africans. This study investigated and analysed the relationship between rural-urban migration and housing delivery in Clermont Township in the Province of KwaZulu-Natal. The participants included the residents of Clermont Township and the representatives of the eThekwini Municipality. Among others, the study found that rural-urban migration is an ongoing process which affects housing delivery in urban areas. As a result it continues to make the objective of ensuring that there is adequate housing for South Africans unattainable. Hence, attention should be paid to the effects of rural-urban migration in housing delivery.

  • Description: The aim of this research was to understand the main factors that explain turnover and retention at DOA Ukhahlamba District and to recommend to the District and Provincial management the appropriate strategy for retaining staff. To be able to achieve this aim, the following research objectives have been visited, namely: a) turnover trends, b) analysis of primary and external turnover factors and c) primarily retention factors. Data for analysing turnover trends was collected from the 2004 to 2007 DPSA and DOA annual reports. Primary data on labour turnover and retention factors was collected from 41 employees across different sections at DOA Ukhahlamba District by means of a questionnaire survey. The data was analysed using statistical methods, including frequency distribution, chi-square test and Pearson product-moment correlation. The findings have revealed that there is no clear pattern of turnover trends at DOA and DPSA, and DOA percentage turnover figures are low in comparison with those of the DPSA. In terms of organizational-specific factors, the top three primary turnover factors were identified, namely: a) communication within the organisation, b) leadership and the organisation and participation in decision making. The research results further revealed that communication within the organization had a significant impact with regard to race, but division, location, and grades did not. With regard to the external factors, research results identified the following most important external labour turnover factors arranged according to their importance, namely: lack of availability and quality of health care services and infrastructural development; lack of available sport and recreation facilities; crime in the area and people living in the neighbourhood; lack of educational opportunities available for the family, and geographic location of place of employment. The findings further revealed the top three retention factors, were strongly significantly correlated to each other, namely: resource availability, use of discretion in handling customer complaints, and the impact of the job on society. These are positively related to intention to stay. The implications these results to the management would require the review of the organisational Human Resource Management Policy and the introduction of Attraction and Retention Policy because at present its is non existence at DOA Eastern Cape. Research limitations: the study did not fully explore ethnicity when analysing the communication within the organisation as a labour turnover factor despite having an organisation that is diverse in nature, future academic research should focus more on labour turnover at management level and moderating variables to external labour turnover factors as there is little research done in this area. The factors identified for labour turnover and retention should be treated with caution as it may not be applicable to all sector Departments in the Eastern Cape and may be limited to Ukhahlamba District due to its geographic location. This study will contribute to the body of knowledge as it will serve as a guide to Eastern Cape DOA and other sector Departments in choosing factors to consider when designing their retention strategy in order to reduce labour turnover. To the academic researchers, the first three primary retention factors identified in the survey have not been seen before, grouped and rated amongst the top three retention factors which therefore means that the management support becomes more important than looking more on salary package as the first priority factor as revealed by most of the research literature consulted (Gustafson, 2002; Mobley, 1982; Mobley, 1979; Herzberg, 2003). This shows that labour turnover and retention factors will not be the same to all organisations, the location of the business and surrounding environment should be considered carefully when designing the appropriate policy and retention strategy of the organisation.

  • Description: This is a tale of two in-depth stories, both produced by one Daily Dispatch journalist, Gcina Nstaluba, in 2009. One was wildly successful - it helped change the face of the government's housing policy and won Ntsaluba SA Story of the Year at the 2010 Mondi Shanduka Newspaper Awards. The other was deemed a dismal failure by Ntsaluba himself. Why? And what can these stories teach us and our students about doing journalism in South Africa?

  • Description: The extensive amount of research conducted internationally in the field of John Bowlby's attachment theory indicates that an insecure attachment between a child and the primary caregiver has a detrimental effect on both social and emotional development in childhood, as well as having a profound effect on psychological development and functioning in adulthood. The present study aimed to explore and describe the therapeutic process of a nine year old with an insecure attachment style within a therapeutic framework, namely Theraplay. The therapeutic process was embedded within Ann Jernberg's Theraplay framework and the case was further contextualized within Bowlby's attachment theory. The case study method was utilized with a purposive sampling technique employed to select the participant. Irving Alexander's content-analytic framework in conjunction with Guba's model of trustworthiness was employed for data analysis. Two needs emerged during the therapeutic process namely the need for nurturance and affection as well as the need for power, control and safety.

  • Description: Family businesses constitute between forty five and ninety percent of gross domestic product world wide. Research shows that within the next five years over fifty percent of executives will retire, highlighting the significance of successful family business successions. Family businesses founded in the “baby-boom” era are of immediate concern to researchers who are working to understand the dynamics around the succession process and ultimately the criteria preventing or enhancing successful successions. The purpose of this study was to better understand the development of successors in family businesses. A detailed literature study was conducted on family businesses and in particular the factors which both positively and negatively affect family business successions. A single case study approach was used to test whether six dynamic variables applied to this case or not. Three sibling brother successors, a sibling sister and their parents were each separately interviewed and the interviews voice recorded. They were asked questions which could be later analysed and used to uphold or negate whether the six dynamic variables applicable to successful family business succession were upheld or rejected. The data was meticulously analysed and similar answers grouped together. Answers which varied from the norm were reported separately. It was found that in all six of the propositions the responses received from the case study respondents upheld the propositions. Thus, families businesses seeking succession, may well understand and take action regarding the six dynamic variables relating to successful family business successions

  • Description: This research study has emerged as a result of my concern regarding the apparent low self-efficacy amongst initial teacher education students in my mathematics education classes. It also reflects a reported renewed interest in values, and the promotion of excellence in education. The effects of a values-based approach to mathematics education towards improving students’ self-efficacy and promoting excellence have been investigated, grounded within my ontology of excellence in mathematics education, which incorporates the values of respect, fairness, accountability, honesty and compassion. An inquiry-based teaching and learning approach formed the framework within which the study took place. Notions of ‘new scholarship’, premised on the view that teaching is about engagement in participatory learning, and the development of communities of creative students, provided the theoretical framework. Both quantitative and qualitative data gathering methods were used. Data-collection tools included affective-disposition statements, interviews, journal entries, as well as a video recording of a mathematics education lesson. The quantitative and qualitative data generated suggest improved levels of self-efficacy amongst the students who participated in the study. The data also suggest that a valuesbased approach to teaching can be used as an effective approach by mathematics teachers – and mathematics teacher educators – for the purpose of promoting the pursuit of excellence. As teacher education worldwide is currently characterised by a lack of vitality in teacher preparation (Grossman, 2008), the findings of this study should provide insights for teacher educators, teachers and policy makers who wish to promote mathematics self-efficacy, excellence and facilitate enhanced vitality within the teaching profession.

  • Description: Debarking of Acacia mearnsii in South Africa has been conducted using mainly manual systems. Labour shortages and reliability of these systems has caused interest in alternative systems that might be able to debark A. mearnsii. The aim of the research is to compare three mechanised debarking technologies used to debark A. mearnsii. Research trials were conducted on the Demuth, Hyena and Hypro debarkers that would form part of semi-mechanised harvesting systems. The debarking technologies were analysed and compared in terms of productivity per productive machine hour (PMH), debarking quality, system costs and the quality of the bark that was produced. Furthermore, the effect that tree volume, strippability and form have on each of the debarking technologies was determined. The debarking technologies were affected by each of the factors researched. Decreasing tree form had a negative effect on the productivity of each of the technologies. An increase in strippability class (strengthening wood-bark bond strength) caused a decrease in the productivity of each of the machines. An increasing tree volume had a positive effect on the productivity for the three debarking technologies. After the debarking had taken place, samples of bark were analysed at a laboratory to determine if it was acceptable for the processing facilities. Each of the debarking technologies produced bark of varying dimensions, but they were all found to be acceptable. The system costs of the three debarking technologies were compared to a manual system cost at tree volumes of 0.1m³, 0.15m³ and 0.2m³. The Demuth debarker had the best system cost for a tree size of 0.1m³, while the manual system was best for tree volumes 0.15m³ and 0.2m³. The Demuth, Hyena and manual system costs were very similar for each of the tree volumes, with the Hypro being a little higher.

  • Description: Throughout the world, but especially in the African continent, international, cross-border and national conflicts are ongoing. In the majority of these conflicts child soldiers are involved in various ways. Judicial problems concerning the prosecution of commanders and leaders of armed groups, irrespective of governmental or not are being solved. Thus, underlying concern is left to the issue of accountability of child soldiers. International, Regional and National protection measures provide for certain judicial standards dealing with children under the age of eighteen. In order to fully understand the difficulties arising from the existence of universal binding measurement dealing with the accountability of child soldiers, one has to be aware of the international, regional and national legislative frameworks. In Sub Saharan Africa, especially in Rwanda, Uganda and the Democratic Republic of Congo, governments face various difficulties, such as the implantation process of international protection measures and ongoing conflicts, making it very difficult to examine the status of accountability measures for child soldiers. States have different minimum ages for accountability for child soldiers. Only a process of international co-operation between governments and non state actors can attempt to deal with the accountability of child soldiers. Not only deterrent, but rather restitution approaches and reintegration programmes should be followed in order to bring justice and achieve results in peace processes.
