  • Description: During the last two decades, political change in South Africa has resulted in significant changes to higher education (HE) admission policies. Increased admission into South African universities has meant an increase in student diversity and different levels of preparedness of the students negotiating their way through their academic studies. Academic success of students remains a focus and one way of addressing this has been the introduction of various extended programmes at South African universities. Extended programmes have various academic development initiatives embedded in the coursework. These are designed to assist the academic progress of students. However, student success remains elusive as so many factors may impact. The purpose of this study therefore, was to investigate the perceptions of the National Diploma (Engineering: Electrical) Extended Programme students with regard to the benefits of the academic development initiatives offered by the NMMU, in order to gain a deeper understanding of their experiences as Extended Programme students. An exploratory sequential research design was employed, consisting of two phases of data collection, following each other successively (Creswell, 2012). The first phase of the data collection involved both quantitative and qualitative data. This was followed by a consecutive collection of qualitative data with the aim to enhance the themes that emerged from the first phase of this study. This mixed-methods research design facilitated the gathering of rich data to answer the research questions. The results indicated that these students perceived the academic development initiatives they received as positive and beneficial to their development. In addition, they felt adequately prepared for the mainstream curriculum; acquired and applied many skills relative to their field; and considered themselves to be at an advantage when comparing themselves to their mainstream counterparts.

  • Description: A swarm of granitic pegmatites occurs in Mzimba district from northern Kasungu to Kafukure near the western international border with Zambia. The granitic pegmatites are hosted by a mobile belt, within the Mozambiquan orogenic belt (c. 900 - 1800 Ma). They have been dated as 485 Ma. They intruded metasediments of high to medium grade metamorphic rocks of a Precambrian Basement Complex. The dominant trend of the pegmatites is NW - SE, exhibiting a cross-cutting relationship with the country rocks and their contacts with the latter are usually sharp. The six pegmatites investigated in this study are inhomogeneous, composed of a massive quartz core, an intermediate zone composed of a blocky pink K-feldspar rich sub-zone and muscovite rich sub-zone and a wall zone composed of quartz - pink K-feldspar - muscovite mineral assemblage. The Mzimba pegmatites are classified as lithium-caesium-tantalum (LCT) family of rare element granitic pegmatites as described by Černý and Ercit (2005). They belong to the beryl-columbite subtype and beryl-columbite-phosphate subtype of the rare element pegmatites. It is suggested that the pegmatites are the product of magmatic differentiation and that they form roofs of granite plutons lying deep below the current level of erosion. The six pegmatites were sampled and minerals analysed using standard analytical methods such as petrographic microscopy, X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis. Mineralogy of the granitic pegmatites indicates that they are predominantly composed of perthitic K-feldspar (perthite), Na-plagioclase (albite), quartz and muscovite as main mineral phases and accessory minerals including beryl, tantalite-columbite (ferrotantalite), iron-titanium oxides (ilmeno-rutile and ilmenite), tourmaline (schorl), garnet (almandine-spessartine) and triplite. Triplite is a very rare mineral found in a few pegmatites around the world, and this is the first reported account of this mineral in the Mzimba pegmatites and probably in Malawi. These minerals are being exploited by artisanal and small scale miners. Trace elements in K-feldspar and muscovite are significant indicators for the evaluation of economic potential of pegmatites as well as for the differentiation degree and origin of the magma. The K/Rb ratio for K-feldspars ranges between 12.72 and 109.38, while for muscovites it is between 16.66 and 82.36 indicating that the pegmatites are moderately evolved. The Ta versus Cs and the Ta versus K/Cs discrimination diagram indicates that all the investigated pegmatites plot above the 20 ppm threshold suggesting that the pegmatites have potential for Ta and Nb mineralization.

  • Description: Despite according high priority to regional economic integration and being clustered by regional economic schemes, Africa’s regional economic integration record is not inspiring. With the transformation of the OAU to the African Union (AU), the New Partnership for Africa`s Development (NEPAD) was adopted as the development program of the continent to drive the impetus of economic integration through trade. At the time NEPAD was adopted, regional integration schemes in Africa were facing problems of low intra-regional trade levels despite trade being identified as the engine of activity and economic growth for regional economic integration. The study was centered on Southern Africa with precise attention on SADC. Even though trade is accepted as a vital engine of economic growth and development, this is not the case with SADC. The study was looking at the contribution of NEPAD in intra-regional trade in Africa with special focus on SADC. This was prompted by the fact that regional integration is business as usual within the sub region while problems that have been confronting regional schemes are continuing unabated after the adoption of NEPAD. The study used the historical approach because it provides the study with an advantage of accessing existing literature with regards to what is really stalling intra-regional trade in SADC. The study findings noted that NEPAD has not fully addressed the problems of intra-regional trade within SADC and the continent at large. The study lastly concludes by giving a way forward for NEPAD to respond to the specific needs of SADC for the promotion of intra-regional and equitable trade.

  • Description: The base metal massive sulfide deposits of the Aggeneys-Gamsberg (A-G) District are hosted within the Mesoproterozoic Bushmanland Group of the Namaqua-Natal Metamorphic Complex in the Northern Cape Province of South Africa. The district displays an apparent eastward trend in the economic concentration of base metals (+ barite) from relatively Cu-Pb-rich, Ba-poor mineralisation at Black Mountain to Zn- and Ba-rich ores at Gamsberg. Base metal sulfides at Gamsberg are restricted to the so called Gams (Iron) Formation which comprises a sulfidic mineralized unit (“B”) enveloped within a sequence of meta-sedimentary units (“A” and “C”). The aim of the study was to shed further light on the genesis and chemical evolution of the sulfide mineralisation at Gamsberg in the context of the entire A-G District, by interrogating further the apparent district-wide trend in base metal distribution. The Gams Iron Formation was sampled and studied from one key drill core intersection (“G1”) which intersects the largest part of it as described elsewhere; a small number of additional samples from a second drill core (“G2”) complemented the main sample suite. Minerals that make up the silicate assemblages across the studied section include quartz, garnet, pyroxene, pyroxenoid, phyllosilicates, carbonates, amphiboles, oxides (chiefly magnetite) and graphite. In a stratigraphic context, the mineralogical variations conform directly to those documented in the relevant literature from the Gamsberg locality. These are coupled, where possible, with mineral-chemical profiles of selected silicate species which replicate those of bulk-rock compositions, particularly with respect to Mn, Fe and Ca in the upper C Unit of the studied section. These signals collectively track the characteristic transition from a terrigenous, siliciclastic sediment-dominated footwall to an exhalative sediment-dominated hanging wall to the sulfide mineralisation as also seen in similar deposits elsewhere, particularly with respect to the characteristic Mn-rich signature increasingly observed in the hanging wall C Unit. The foregoing suggests that the examined section faithfully records the interpreted primary stratigraphy of the deposits, despite the complex structural and metamorphic overprint that characterises the region. This facilitates a stratigraphic analytical approach on the sulfidic Unit B, through a combination of mineral-chemical and stable isotope analyses. Dominant sulfides in Unit B are sphalerite and pyrite, with lesser pyrrhotite and minor galena. Sphalerite shows high and generally invariant contents of Fe (mean 12.18wt%, as FeS) whereas Zn anti-correlates with Mn (mean 5.58wt%, as MnS). Isotopic analyses for S, Fe and Zn in hand-picked sphalerite and pyrite separates were used with a view to providing new evidence for chemical and isotopic variation within the sulfide ore-body in a vertical (i.e. stratigraphic) sense, discuss the implications thereof, and ultimately interpret the new data in light of similar existing data from the A-G District and elsewhere. The δ³⁴S data for pyrite (plus a single pyrrhotite grain) and sphalerite from both cores G1 and G2 show comparable compositional ranges between 22.9 and 30.4‰ and between 27 and 30.1‰ respectively. The δ⁵⁶Fe data for pyrite show a range between -1.85 and 0.19‰, whereas seven sphalerite separates have a very narrow range of δ⁶⁶Zn from 0.06 to 0.20‰. The atypically high sulfur isotope data reported in this study are interpreted to reflect sedimentary deposition of primary sulfide ore at Gamsberg from an isotopically highly evolved seawater sulfate source through large-scale Rayleigh fractionation processes. Thermogenic sulfate reduction is proposed to have been the main reductive mechanism from seawater sulfate to sulfide, given the absence of very low δ³⁴S data for sulfides anywhere in the A-G District. By contrast, the δ⁶⁶Zn values for sphalerite are for all intents and purposes invariant and very close to 0‰, and therefore suggest little Zn isotope fractionation from an original exhalative fluid source. On this evidence alone, Zn isotopes therefore appear to hold little promise as a proxy of the chemical and isotopic evolution of SEDEX deposits in space and time, although this can only be verified through further application in the broader A-G District and similar deposits elsewhere. The apparent decoupling of Zn and S isotopes in the Gamsberg sulfide deposit, however, points towards diverse sources of these two components, i.e. ascending metalliferous brines versus seawater respectively. Finally, pyrite δ⁵⁶Fe data do show a stratigraphic trend of generally declining values up-section, which are interpreted to reflect the influence of broadly coeval precipitation of isotopically heavy Fe-oxides on a broader-scale – now preserved as abundant magnetite through metamorphism. Further work on the iron isotope composition of silicate-and oxide-hosted Fe on a local-to-district scale will assist in testing this interpretation.

  • Description: The main objective of this study was to explore non-governmental organisations (NGOs) and poverty reduction strategies in Zimbabwe through an assessment of the activities of the Catholic Development Commission (CADEC) in the Binga district in the Matabeleland North province. The research method used was triangulation and the theoretical framework combined insights of both the Basic Needs Approach and the Capability Theory. The core argument which has emerged is that despite criticisms levelled against NGOs that they cater for immediate relief and basic needs, the operation of CADEC in Binga shows in contrast that NGOs can operate in such a way that the capabilities of the participants can be enhanced or expanded such that the Binga district can be capable of independently engaging in sustainable livelihoods and development. This study argued that participation in projects has enabled CADEC to realise and expand people’s capabilities and participation was identified as a means of gaining a sustainable livelihood. To achieve the objectives of the study the researcher collected data using a survey questionnaire and in-depth interviews. The study was framed within the concept of Fundamental Human Needs by Manfred Max-Neef and the Capabilities Approach of Amartya Sen. The concept of Fundamental Human Needs argues that human needs do not change but the ways of satisfying the needs do change and unsatisfied needs results in poverty. The Capabilities approach on the other hand, sees poverty as caused by the deprivation of human capabilities. These theories were utilized for this study because they complement each other. Max-Neef believed that development should focus on promoting community agency where beneficiaries are the primary actors for development. Development for him is people-centred, participatory and environmentally sound whilst the Capability Approach of Sen is of the view that development is about developing or expanding human potentials. Being anchored on these two theories this study found out that CADEC use supplementary feeding, sustainable projects such as gardens and livestock production, educational initiatives, the provision of shelter and participatory development as strategies to alleviate poverty in the Binga district. CADEC’s long term projects that focus on farming practices and sustainable livelihoods have enabled Binga people to respond to their poverty. Thus, the results of this study substantiated the views on Max-Neef and Sen since CADEC does not only provide for basic needs but also enhances the capabilities of the people in Binga. However, even if the majority of the respondents believed that CADEC has managed to reduce poverty in Binga, a lot still needs to be done since poverty is still the main problem in the district.

  • Description: The study aims at interrogating the self - perceptions of journalists in Nigeria. The study is an attempt to answer some questions as: what contributions have journalists made to the democratization of Nigeria from 1960 to date? What role(s) did the media play during and after the transition to democracy? To what extent have the activities of politicians and the business class affected t he media’s social responsibility? What are the self-perceptions of journalists working in Nigeria’s The Guardian newspaper? The studies on normative theories of the press, Journalism Culture, and the perceived influences on journalism practice in a democra cy were adapted to answer the afore-listed questions. The works on how elite continuity and transitology models affect the perceptions of journalists in new democracies were also used to answer the questions posed. Since the field of research of the preced ing works is the West, the Nigerian experience points to issues that were not addressed in the prior studies because of the latter’s unique socio-political, historical, economic and ethno-religious structures . The data were collected and analyzed according to the QualitaQualitative paradigm, using in-depth semi-structured individual interviews with journalists working at The Guardian newspaper. The findings suggest that the journalists have made positive contributions to Nigeria’s democratization. The journalists that support this thesis claim that the self-perceptions of their role have changed from an adversarial position to a democratically-defined social responsibility role. This is because journalists ensure that government policies are implemented and the iss ues that affect the masses are reported. The findings show that in spite of the shift to democratization some challenges have remained, for example the journalists’ lives are not safe ; they collect bribes which are popularly called brown envelopes in Nigeria, write biased stories, and hold partisan relationships with the politicians and entrepreneurial elites and so on. The study acknowledges that democratization is in a continuum and that (the stakeholders or) civil society, journalists, the state and the entrepreneurial elites must contribute to deepen Nigeria’s democracy. The study suggests a self-perception theory that uses individual structures and institutions of a country to guide the stakeholders to play roles that will deepen democracy.

  • Description: The focus of the research was on numerical errors committed in foundation phase mathematics. It therefore explored: (1) numerical errors learners in foundation phase mathematics encounter (2) relationships underlying numerical errors and (3) the implementable strategies suitable for understanding numerical error analysis in foundation phase mathematics (Grade 3). From 375 learners who formed the population of the study in the primary schools (16 in total), the researcher selected by means of a simple random sample technique 80 learners as the sample size, which constituted 10% of the population as response rate. On the basis of the research questions and informed by positivist paradigm, a quantitative approach was used by means of tables, graphs and percentages to address the research questions. A Likert scale was used with four categories of responses ranging from (A) Agree, (S A) Strongly Agree, (D) Disagree and (S D) Strongly Disagree. The results revealed that: (1) the underlying numerical errors that learners encounter, include the inability to count backwards and forwards, number sequencing, mathematical signs, problem solving and word sums (2) there was a relationship between committing errors and a) copying numbers b) confusion of mathematical signs or operational signs c) reading numbers which contained more than one digit (3) It was also revealed that teachers needed frequent professional training for development; topics need to change and lastly government needs to involve teachers at ground roots level prior to policy changes on how to implement strategies with regards to numerical errors in the foundational phase. It is recommended that attention be paid to the use of language and word sums in order to improve cognition processes in foundation phase mathematics. Moreover, it recommends that learners are to be assisted time and again when reading or copying their work, so that they could have fewer errors in foundation phase mathematics. Additionally it recommends that teachers be trained on how to implement strategies of numerical error analysis in foundation phase mathematics. Furthermore, teachers can use tests to identify learners who could be at risk of developing mathematical difficulties in the foundation phase.

  • Description: In this thesis an ionospheric tomographic algorithm called Multi-Instrument Data Anal- ysis System (MIDAS) is used to reconstruct electron density profiles using the Global Positioning System (GPS) data recorded from 53 GPS receivers over the South African region. MIDAS, developed by the Invert group at the University of Bath in the UK, is an inversion algorithm that produces a time dependent 3D image of the electron density of the ionosphere. GPS receivers record the time delay and phase advance of the trans- ionospheric GPS signals that traverse through the ionosphere from which the ionospheric parameter called Total Electron Content (TEC) can be computed. TEC, the line integral of the electron density along the satellite-receiver signal path, is ingested by ionospheric tomographic algorithms such as MIDAS to produce a time dependent 3D electron density profile. In order to validate electron density profiles from MIDAS, MIDAS derived NmF2 values were compared with ionosonde derived NmF2 values extracted from their respective 1D electron density profiles at 15 minute intervals for all four South African ionosonde stations (Grahamstown, Hermanus, Louisvale, and Madimbo). MIDAS 2D images of the electron density showed good diurnal and seasonal patterns; where a comparison of the 2D images at 12h00 UT for all the validation days exhibited maximum electron concentration during the autumn and summer and a minimum during the winter. A root mean square error (rmse) value as small as 0.88x 10¹¹[el=m³] was calculated for the Louisvale ionosonde station during the winter season and a maximum rmse value of 1.92x 10¹¹[el=m³] was ob- tained during the autumn season. The r² values were the least during the autumn and relatively large during summer and winter; similarly the rmse values were found to be a maximum during the autumn and a minimum during the winter indicating that MIDAS performs better during the winter than during the autumn and spring seasons. It is also observed that MIDAS performs better at Louisvale and Madimbo than at Grahamstown and Hermanus. In conclusion, the MIDAS reconstruction has showed good agreement with the ionosonde measurements; therefore, MIDAS can be considered a useful tool to study the ionosphere over the South African region.

Options for eland: a multi-scale assessment of antipredatory responses of a vulnerable prey species to their dominant predator in the Eastern Cape, South Africa

  • Description: Eland Tragelaphus oryx are the largest and slowest African antelope, falling within the preferred weight range of the prey of lions Panthera leo. Little is known, however, about the antipredatory strategies employed by eland. Rapid population declines in several small reserves following the reintroduction of lions suggest that the antipredatory strategies of eland may be compromised in spatially limited areas. This emphasises the need for research aimed at investigating how eland respond to lions, particularly in the spatial context, given that lions are increasingly being reintroduced into small reserves in South Africa. This study aimed to investigate lion-eland interactions at multiple scales and determine where on the landscape eland were vulnerable to predation. Adult female eland (n = 3 per site) in breeding herds were collared with GPS satellite collars in two study sites; the Nyathi section of Addo Elephant National Park (Nyathi) and Mountain Zebra National Park (MZNP) in the Eastern Cape, South Africa. A reintroduced population of lions, comprising two males and one female, was present in each study site, with individuals fitted with GPS satellite collars. At a broad spatiotemporal scale, eland did not avoid lions and there was considerable overlap between eland and lion home ranges in both study sites. At a finer spatiotemporal scale however, eland and lion space use was asynchronous in time, except in the case of the female lion in Nyathi where there was considerable overlap at the finest temporal scale investigated (i.e. monthly). Herd-associated eland in Nyathi were killed most frequently in areas associated with high long-term use by the female lion, showing that failure to avoid the female lion at a fine scale increased predation risk for eland. Secondly, eland in Nyathi were killed most frequently in habitat types of intermediate structural density (i.e. mixed habitats), which limited the viewshed of eland but presumably offered increased forage. This habitat type was selected for by eland, despite it being associated with a higher level of predation risk. This suggested that eland in Nyathi traded off safety for forage. In MZNP, predation of herd-associated eland was low which reflected the limited spatial overlap between eland and lion at a fine scale in this reserve. In Nyathi, but not in MZNP, eland responded to lions within 1.5 km by increasing their movement rate, with this response particularly strong at night. The findings of this study show that eland responses to lions are scale-dependent and site-specific. Furthermore, eland responses to lions were shown to be lion gender-specific. This study has increased our understanding of the antipredatory behaviours of eland and demonstrated the importance of investigating prey responses to predation risk at multiple scales.

  • Description: The Navachab Gold mine, an orogenic lode gold deposit, is located in the Karibib region of the Pan-African (ca. 550-500) Damara belt of central Namibia. Gold mineralisation is developed within the steeply NW dipping limb of the Karibib dome. Here, ore envelopes trend along three main orientations: a) trends shallowly towards the NE (the down plunge extent), b) trends sub-vertically in and along the down plunge extent and c) trends sub-horizontally across the down plunge extent. The down plunge extent represents the bulk of the gold mineralisation, hosting the only high grade ores mined at Navachab. As such, past work primarily focused on establishing the controls to the mineralisation observed here. The sub-vertical and sub–horizontal ore trends are seen as secondary, lower grade, being hosted in the footwall. By cutting pushbacks into the footwall, in an effort to regain access to high grade pit bottom, future gold production almost exclusively relies upon optimally mining these ores. This underlines the importance to investigate and outline the mineralising controls to the secondary ore trends. This study identified the following prevailing quartz vein sets developed within the footwall, set (1) dips shallowly towards the NE (conjugate vein set), (2) steeply towards the NW (bedding parallel veins) and (3) steeply towards the SE (S2 foliation parallel). The NW and SE dipping sets contain high average gold grades, occurring at an infrequent vein density. The NE dipping veins, as a result of occurrence density alone, was highlighted as the dominant gold hosting set. Veining occurred during the late stages of the NW-SE directed, sub-horizontal shortening (D2) event and is associated with top-to-the-NW thrusting and NW-verging folds. Re-Os molybdenite dating from auriferous quartz veins indicates mineralisation occurred at 525-520 Ma. As crustal shortening amplified the Karibib dome, flexural flow developed fractures along bedding planes, providing the control to bedding parallel veins (NW dipping). With continued crustal compression the dome later experienced fold lock up associated with reduced mean rock stress and sub-horizontal extension occurred along the steeply NW dipping limb. Horizontal extensional gashes sucked in fluids to form the shallowly NE dipping conjugate vein set. These features suggest the regional D2 strain as the first-order control to quartz vein development, down plunge and within the footwall ores. To further define the secondary ores, lithological and structural controls were evaluated on a more detailed local scale. With equal amounts of biotite schist and calc-silicate host rock (bulk of the footwall lithology) material analysed, the biotite schist units were found to contain a larger volume amount of quartz veins. The mineralisation incurred is also developed at higher average gold grades compared to that of the calc-silicates, demonstrating biotite schist having the optimal rheology for quartz vein emplacement. Normal faulting and thrusting occurs widespread, at all scale levels, across the footwall. These were primarily observed along bedding foliations and secondly at higher angles cutting across foliation. The study did not constrain the extent of these, but can conclude faulting plays a very prominent role in re-distributing the secondary ores parallel to bedding along sub-vertical trend planes. Great care should be placed in properly modelling these with 3D software such as Leapfrog. The Navachab gold mineralisation came about as a result of convergent and collisional tectonics activating metamorphic dehydration of the crustal metapelites. As these fluids ascended they absorbed gold from the crust, emplaced by either a magmatic or paleo-placer source. The gold enriched hydrothermal fluids amalgamated in large scale 1ste order structures (shearing of the steep NW limb of the Karibib Dome, the Mon Repos Thrust Zone) that acted as primary active fluid path ways. In the case of Navachab the gold enriched fluid fluxed along these pathways while interacting with fluid sinks related to a physical throttle (brittle schist, folding, bedding parallel shears) and/or a chemical trap (marbles). By summarising and detailing the fluid sinks and active fluid pathways identified by this and previous works, it is strongly recommended that a mineral approach system be designed and implemented as targeting model to lead future exploration endeavours.

  • Description: From Integrative summary: This document consists of three sections namely, an evaluation report (section 1), literature review (section 2), and research methodology (section 3). The evaluation report sets out the terms of reference for the research as well as identifying the objectives of the research. It also contains a summary of the literature review section, as well as a research methodology section summary. The literature review section contains a detailed review of the literature used in this study. This section sets out by reviewing existing literature on the topic of leadership, discussing the key elements of organisational culture and includes a short discussion on the typologies of culture. The Competing Values Framework as an organisational culture typology is discussed in greater detail, since it forms the foundation upon which the measurement and data collection tools for this research are founded. The research methodology section explains the research methodology and design employed in this study. This section also addresses some of the ethical considerations for this research, as well as how the researcher addressed them. There is also a brief discussion on the limitations of the research and the application of the results. This research focused on a business unit within Absa Business Bank, named Enterprise Business Gauteng Region, with the aim of investigating the “current organisational culture” in the business unit and the leadership competencies profile of its 11 Sales Managers. This was to provide the basis and departure point for the strategic organisational culture change that the new business unit head would have wanted to effect as the business has a history of non-performance, which the new business unit head aims to change. In order to diagnose the “current organisational culture” type, an organisational culture measurement tool based on the Competing Values Framework was used. The Competing Values Framework is a four-category organisational culture typology developed by Cameron and Quinn. The framework is based on two dimensions, how stable or flexible the organisation is, and how externally or internally focused it is. This framework was also employed to establish the leadership competencies profile of Sales Managers, as observed and experienced by the frontline staff, as well as the “desired organisational culture”, as intended by the new business unit head. Through hypotheses testing, the research revealed a statistically significant difference in perceptions of culture between males and females in the business unit. The perceptions of the female frontline staff about the “current” business unit culture indicated that they find it not to be empowering and less allowing for individuality and risk taking when compared to the male staff. The research also concluded that there is no statistically significant difference between leadership competencies associated with the four categories of the Competing Values Framework in the business unit. Comparisons between the “current” and the “desired” organisational culture revealed a misalignment. The main recommendations to the new business unit head were to get the leadership competencies of the Sales Managers aligned with the “desired organisational culture” state, and drive a purposive organisational culture change effort. To support this culture change, the espoused values of the business unit would need to be aligned to the desired culture state. To address the differences in perceptions of culture between males and females the business unit head would need to be mindful of the greater need to empower women either in their current roles, or by way of promotions to senior roles.

  • Description: The increased incidence of children committing crime and the realisation that the existing legislature dealing with offenders failed to cater for the rights and needs of child offenders gave rise to the introduction of the Child Justice Act 75 of 2008. This Act enables the South African criminal justice system to deal with children in a manner appropriate to their developmental stage. One of the initiatives introduced by the Act is termed ‘diversion’, where children are diverted from the criminal justice system into restorative developmental programmes, offered by organisations such as NICRO (National Institute for Crime Prevention and the Reintegration of Offenders). Their parents or guardians are tasked with the responsibility of monitoring their compliance with the diversion order in terms of Section 24(5) of the aforementioned Act. The monitoring responsibility assigned to the parents of diverted adolescents prompted the research question and aim of this study, namely to explore parents’ experiences in monitoring their adolescents’ compliance with diversion orders and to identify service needs in supporting parents in fulfilling their role as stipulated in the Act. This was a qualitative study that was exploratory-descriptive and contextual in nature. A non-probability purposive sampling technique was employed to identify the parents or guardians of adolescents aged 14 to 17 years that had been diverted to NICRO between June 2011 and June 2012. Individual semi-structured interviews were conducted with the selected parents, and the data collected was analysed using thematic data analysis. The trustworthiness of the research process and the findings was enhanced by employing a variety of data verification strategies. This research contributes to a greater understanding of parents’ monitoring experiences of their adolescents’ compliance with diversion orders. The study revealed that most parents experienced their role as an additional responsibility; they needed access to counseling and information on the child justice process.

  • Description: Academic support is critical in promoting success among student nurses. Support for student learning is a key element in optimizing student learning experiences, in any learning environment, and its importance has been widely discussed. Student academic support is closely related to motivation for learning, and helping students achieve their learning goals and objectives. Student nurses continue to struggle during their training, to the point of failing a year or being excluded from the course, in spite of the academic support provided through classroom facilitation, and remedial teaching provided by academic staff. They frequently complain that the course is difficult, the workload is heavy, and they are unable to integrate theory with practice. As a result they are too stressed, throughout their training. The purpose of this study is to explore and describe the perceptions of student nurses about the academic support provided to them at a public nursing college in the Eastern Cape Province. This study was guided by the Caring Curriculum Model, based on Watson‟s Theory of Caring. The core of this theory is the implementation of ten carative factors to promote health and equilibrium. Caring was endorsed as a core value in nursing education and practice, by the National League of Nursing and the American Association of Colleges of Nursing, while the centrality of a caring-healing relationship was recognized as a basis for all health professional education by the Pew Health Professions Commission. A quantitative approach, using a descriptive and explanatory design, was used to determine the perceptions of student nurses on the academic support they received from the public nursing college. Participants were selected by a simple random sampling method. A total of 189 student nurses, who registered for the 4-year diploma programme at the East London Campus of the Lilitha College of Nursing, participated in the study. Self-report data was collected by means of the Academic Support questionnaire, using a Likert scale which addressed both the performance and importance of academic support. Data were analysed using Statistical Analysis Systems version 9.3, using mean tables and graphical data analysis. The findings revealed high performance ratings for aspects relating to academic advising and teaching-learning process, indicating that there is satisfaction among students on these service attributes. Poor performance ratings were identified, relative to campus support services, indicating that student nurses were not happy with the availability and accessibility of library resources, and computer and internet services. Student nurses, at the college under study, were also not happy with aspects of service excellence relating to campus-based health care facilities, and personal student counselling services. The study identified a gap between the perceived performance and the importance of academic support at the nursing college, as the general performance was rated lower than the importance of academic support. The findings suggest the necessity for improved library facilities and resources, healthcare and counselling services and the establishment of student support programmes, to build the capacity of students and to enhance their chances of success.

  • Description: The purpose of the study was to examine the perceptions of learners and teachers on the alternatives to ‘Alternatives to Corporal Punishment’ (ATPC) in particular and discipline generally in the King William’s Town Education District in two high schools. The study ascended as a result of the decline of learner’s discipline in high schools. This study is located in the interpretive paradigm and adopted a qualitative research approach using questionnaires, interviews focus groups and field notes in the collection of data. The Data revealed that schools were using different strategies to maintain learner’s discipline such as Code of Conduct, Disciplinary hearing, Safety and Security Committee, Educators, Corporal Punishment, Alternative methods to Corporal Punishment and the role of parents. It further revealed that the Department of Education is not supportive in the maintenance of discipline in the schools under study in King William’s Town District. The conclusion that was arrived at was that all the stakeholders should agree upon and be acquainted with the Code of Conduct and rules that are guiding the schools. The study came up with the proposal that learners should know the consequences of transgressing the Code of Conduct. To address disciplinary problems, the study came up with the key recommendation that all stakeholders must have ownership and to work as a team in the implementation of those policies.

  • Description: Chinese organisations are benefiting from increasing support from the Chinese government to enter into Africa. It is believed that over 2 000 Chinese organisations are operational in Africa, contributing greatly to employment within the continent. Despite the importance of Chinese organisations and their operations in Africa, very little research has been done on individual and organisational issues in Chinese organisations operating in Africa, and more specifically the local employees' organisational commitment to such organisations. The organisational commitment of South African employees within Chinese organisations in South Africa is important as it promotes the success of Chinese business, which may promote further investment into the country, as well as the use of local human resources. The primary aim of this research was therefore to conduct a literature and empirical study into the levels of and factors influencing the organisational commitment of South African employees in a selected Chinese organisation in South Africa. For the purposes of this study, a single case study approach, located within the phenomenological research paradigm, was used. A large multinational Chinese organisation with operations in South Africa agreed to participate in this study. The research made use of a descriptive case study design. To give effect to the primary aim of the study, three research objectives were identified. Firstly, to identify and describe key factors influencing local employee commitment. Secondly, to identify and describe current commitment levels amongst local employees, and lastly, to propose recommendations to improve local employee commitment and its implications for the appropriate management of human resources within the Chinese organisation. Data were collected by means of in-depth, semi-structured interviews with 20 participating employees at four organisational branches across South Africa. Moreover, although the interview transcripts were the primary source of data, the collection process was enriched with the use of organisational and participant observations. The findings of this research revealed ten factors which are perceived to influence the commitment of South African employees within the organisation, namely: Open communication, Leadership, Supervisory support, Opportunities for training and development, Compensation, Job security, Promotional opportunities, Shared values, Recognition and Trust. Certain issues were raised by the participants during the in-depth interviews, most notably the limited opportunities for training, development and promotion, as well as issues regarding the perceived limited compensation received from the organisation. Despite these issues, the general findings relating to the levels of commitment in the organisation were positive for the organisation under study, with the majority of the participants being perceived to demonstrate high levels of affective, normative and continuance commitment.

  • Description: The World Health Organization (WHO) states that no region in the world is justified in having a caesarean section rate greater than 10-15 percent, calculated as the number of caesarean deliveries over the total number of live births. There is however, an international increase in the rate of caesarean section deliveries and this is a concern to midwives. The increase is evident in South Africa as well. Currently the rate of caesarean section deliveries in the private sector can be as high as 70 percent per total number of live births per year. As a result, the public often perceives giving birth surgically in South Africa as ‘normal’ and ‘safer’ than vaginal delivery, even for low-risk pregnancies. The lack of involvement of midwives in the care of pregnant women in the private sector is indicated as one of the reasons related to the high caesarean section delivery rates. This motivated the researcher to undertake a study to explore and describe the perceptions of private sector midwives and obstetricians regarding the feasibility of collaboration in maternity care. A literature review to support the study identified research done previously regarding collaborative maternity care. The study followed a qualitative, exploratory, descriptive, contextual design. The research population included midwives and obstetricians in the private sector in the Eastern Cape. Non-probability, purposive sampling was used. The researcher conducted semi-structured one-to-one interviews to collect information rich data. The researcher ensured that the study was conducted in an ethical manner by adhering to ethical principles such as autonomy, non-maleficence, beneficence and justice. The interviews were transcribed and Creswell’s’ data analysis spiral was used as a guide for the data analysis. Themes and sub-themes were identified and grouped together to form new categories. An independent coder assisted with the coding process. Data analysis results revealed the following results Participants perceived a collaborative working relationship as being beneficial to maternity care. Participants identified that there might be critical impediments that need to be faced in order to realize collaborative maternity care. The researcher ensured the validity of the study by conforming to Lincoln and Guba’s model of trustworthiness, which consists of the following four criteria namely credibility, transferability, dependability and conformability. The information obtained from this study assisted in developing guidelines to facilitate the implementation of collaborative maternity care between midwives and obstetricians in private practice in South Africa. The objective of the study was thus met.

  • Description: The objective of the study was to determine perceptions of the consumers on how they judged behaviour and beef quality of cattle slaughtered for traditional ceremonies in the Eastern Cape Province of South Africa. A survey was conducted where a sample of 200 consumers were randomly selected and interviewed. Fifty non-descript cattle were slaughtered during traditional ceremonies and two hundred and twenty four (224) cattle were slaughtered at 3 through-put abattoirs (high, medium and low). Meat quality attributes were determined from the cattle slaughtered for traditional ceremonies and from cattle slaughtered at the abattoirs. Data for questionnaires was summarized as frequencies for each ceremony and statistical differences were analysed using chi square test (X2). The effect of Age, breed and sex on beef pH, colour, meat tenderness, temperature and cooking loss of cattle slaughtered during traditional ceremonies, at low, medium and high throughput abattoirs were analyzed using General Linear Model (PROG GLM) of SAS (2003). There was a significant age effect (P < 0.05) on beef tenderness and cooking loss of cattle slaughtered for traditional ceremonies. Age of cattle that have milk teeth to 1 year and age of 6 years to 8 years had an effect on the beef tenderness (25.55 ± 8.05) and cooking loss (48.00 ± 4.26) of cattle slaughtered for traditional ceremonies in Table 4.1. There was no significant sex effect on beef tenderness and cooking loss of cattle slaughtered for traditional ceremonies. Non-descript and Angus cattle slaughtered at low throughput abattoir had an effect on the colour of the beef in Table 4.2. The lightness (27.49 ± 2.53) and yellowness (21.16 ± 0.79) of the beef shows that there was a significant breed effect on cattle that are slaughtered at Low throughput abattoir, however redness of the meat was not affected by breed after slaughter. Cattle that are slaughtered at high throughput abattoir between ages of 6 to 8 years and also cattle that are more than 8 years in Table 4.4 had an effect on cooking loss (p < 0.05). Age between 6 to 8 years had an effect on the beef tenderness from cattle that are slaughtered at medium throughput abattoir. It was concluded that the meat tenderness of the young cattle with milk teeth slaughtered for traditional ceremonies was affected. On the other hand the meat tenderness and cooking loss of beef from the cattle slaughtered from low, medium and high throughput abattoir were affected by sex and breed mostly.

  • Description: South Africa plays a very important role on the African continent, both politically and economically. She is often the main protagonist behind various peace-making efforts both regionally and continentally, and now she plays an even more important part in the African Union. In July 2012 South African candidate Nkosazana Dlamini-Zuma was elected as chairperson of the African Union Commission, in an election which highlighted a need to investigate the perception of South Africa in the African Union. South African foreign policy has gone through various stages, from being internationally isolated during the apartheid era to being on the forefront continentally during the successive post-apartheid presidents. The electoral discourse in 2012 however, highlighted some divergent opinions on South African foreign policy which this study investigates. What was identified during the election campaign was a possible negative perception of South African foreign policy, both politically and in terms of the private sector. The study sought to investigate how South Africa is perceived on the African continent, and in order to reach a conclusion it performed a policy analysis as well as a qualitative discourse analysis of the statements given during the election. The policy analysis contextualises and explains South African foreign policy agendas and choices, and the discourse analysis sought to reveal any negative perceptions of South African foreign policy. The findings of the study are that there is a general negative perception of South Africa and her foreign policy in Africa, due to several reasons, which will be discussed in the following study. The negative perceptions stem from the Eastern region, the Western region, as well as from South Africa itself, through political analysts and experts.
