  • Description: The global working environment has transformed significantly over the last two decades, with rapid advancements in technology and information as well as the levels of diversity in the workplace. This process of adaptation, the failure to adapt or weaknesses in adaptation can be an underlying cause of conflict within organizations. For an organization to be successful, there must be effective conflict management techniques in place in order to resolve or keep the conflict at a minimum. The aim of this exploratory case study was to therefore explore the management of conflict between employees in an Information Technology company in Johannesburg. The human needs theory, which states that the deprivation of human needs is a major source of conflict, was used as the theoretical framework guiding this study. A mixed methods approach, also known as methodological triangulation, was used, which involved combining qualitative and quantitative research methods in order to achieve triangulation of data. The qualitative research method that was used comprised individual semi-structured interviews with two Human Resources managers and the quantitative research method involved the completion of self-administered questionnaires by 94 employees of the IT company. The researcher used a purposive sampling design for the interviews and simple random sampling for the questionnaires. Ethics permission for this research was received from Nelson Mandela University’s Research Ethics Committee and the study was conducted in accordance with the university’s Policy on Research Ethics. The findings of this study have revealed that the type of conflict mainly experienced in this organization was employee conflict, due to interpersonal clashes relating to personality differences. The employees were unanimous that conflict can have both a positive and negative effect. The interviews confirmed that the IT company makes use of negotiation and mediation to resolve workplace conflict, with the literature review providing evidence that negotiation and mediation are useful means of managing conflict between employees. However, the results from the completed questionnaires revealed that employees attempt to manage conflict by avoiding the conflict, which could be due to employees having limited awareness of the organization’s procedures to address conflict. This study can therefore potentially be beneficial to organizations and assist the latter in developing conflict management skills and practices, which can enhance organizational performance, productivity and employee retention.

  • Description: The Lower Permian Ecca Group formations of the Karoo Basin of South Africa have recently been identified as a target for shale gas exploration. These units, named the Prince Albert, Whitehill and Collingham formations, comprise organic-rich shales with occasional associated carbonate deposits, and siliciclastic facies. Mineralogical and geochemical investigations were conducted into carbonaceous shales and associated sedimentary rocks in the Jansenville area of the southern Karoo Basin with the ultimate aim to decipher the paleoenvironment and post-depositional conditions of these shales and their associated features such as prominent intra-formational carbonate deposits. Sediments of the main Karoo Basin were deposited from ~350 Ma to ~182 Ma, the end of sedimentation being marked by eruption of basaltic lava. This period, which began with the Dwyka continental glaciation, included tectonism of the Cape Fold Belt, the end-Permian mass extinction at ~250 Ma, and major intrusion of dolerite associated with the lavas of the Karoo Large Igneous Province. Subsequent to this, the basin experienced faulting associated with Gondwana breakup, uplift and intrusion of small volume kimberlite and melilite magmas, and erosion resulting in formation of a major escarpment. Each episode was imprinted upon the Karoo rocks and to a greater or lesser extent erases the signature of older episodes. To decipher the depositional paleoenvironment and post-depositional conditions of the black shales and the dolomite concretions posed a challenge due to deformation, orogeny, metamorphism, and weathering and erosion. Therefore, deep borehole core-logging and sampling was generally preferred over surface fieldwork, and trace elements backed up by scanning electron microscopy-based petrography was the method most relied upon to decipher the redox conditions of the black shales and the intra-formational carbonates. Relevant sections from three SOEKOR boreholes SP1/69, AB1/65 and QU1/65 were logged and carbonate concretions localities studied in four field locations. Samples collected from the core and field localities were prepared for thin section optical, SEM petrographical analysis, mineral identification, modal estimation by XRD, major, and trace element analysis by XRF and Laser Ablation-ICPMS, and acid leaching of a sample subset to determine the degree of pyritization (DOP). Logging of the SOEKOR boreholes indicates that in the western part of the basin all three lower Ecca formations, namely the Prince Albert, Whitehill and Collingham, overlie the tillites of the Dwyka Group, whereas near East London only the Whitehill Formation is present. Dwyka diamictites occur in all the studied boreholes overlying the crystalline basement in AB 1/65 and QU 1/65 boreholes whereas in the SP 1/69 the tillites rest above the quartzite of Witteberg Group of the Cape Supergroup. The shale consists of discontinuous, wavy and straight parallel laminae. Parallel, discontinuous and elongate micro-lenses of very fine-grained quartz are diagnostic and suggest late-stage silicification. Thin laminae of black shale are interlaminated with grey clay. The black shales are composed of quartz and clay minerals (illite and chlorite) as the major crystalline minerals with minor quantities of sulphides and heavy minerals. Organic matter occurs as unstructured, anhedral patches of amorphous material. It contains abundant small (~10nm) and less common larger (~100 nm) pores of subsphaeroidal shape. Carbonates occur as cementation and concretions. Heavy minerals identified by SEM include detrital zircon, thorite, titanite, authigenic fluorite, galena, sphene, and sphalerite and apatite, monazite and epidote-group minerals that appear to be of later stage metamorphic origin, some a product of hydrothermal feldspar alteration. Zircon and monazite show evidence of partial corrosion and/or new overgrowth. Titanite occurs in greater abundance in the SP1/69 section than other boreholes, where it exhibits a porphyroblastic texture suggesting secondary growth. These features all suggest modification of detrital minerals by metamorphic fluids and therefore some possible modification of bulk geochemical composition. Pyrite is abundant, commonly occurring as framboidal and occasional euhedral grains. Pyrite-bearing, calcite veins are common in the Whitehill Formation. Some pyrite is metamorphosed to pyrrhotite in the shales adjacent to dolerite intrusions. The carbonate deposits in the lower Ecca occur mostly as large concretions of 0.5-2.5 m in diameter at intensely faulted areas, and as laterally continuous beds at less intensely faulted areas. They consist of dominant dolomite with calcite (differentiated by thin section staining) and minor associated quartz veins, and appear to have formed in an early diagenetic stage of the black shale. Five different dolomite-rock textures were identified indicating varying crystal growth conditions. Calcite cementation types accompany these dolomite textures. The major types include mosaic, sparry and bladed/prismatic calcite cement. Calcite occurs mainly as cement in pores and grain replacement, as well as crudely radial septerian veins. XRD indicates that the carbonate concretions are made up of more than 90% dolomite, especially within the intensely folded areas. The remaining 10% consist of post-depositional quartz veins and secondary calcite associated with the quartz veins. In one locality (VAAL) the carbonate samples are dominates by bladed/prismatic calcite. The black shales in this study have similar geochemical signature to previously analysed samples from the Karoo Basin and to black shales worldwide. The geochemical signature results from the combined input of detrital sedimentary materials as well as enrichment or depletions acquired from pore water, biological activity and during diagenesis. Positive correlation of K2O, Na2O with Al2O3 suggests control by the detrital contribution. CaO and P2O5, have a negative correlation with Al2O3 suggesting a biogenic source. Elemental ratios suggest that the sediments derive from felsic source rock, most likely Cape Supergroup and underlying crystalline basement. These shales exhibit different degrees of trace-element enrichment relative to global average shale, the approximate order being Pb> V> Zn> Cr> Cu> Co > Ni. Assessment of selected trace elements, V/(V+Ni), V/Cr, Ni/Co and EF Mn ratios describes the paleoenvironment of these sediments to have been partially oxygenated before sulphate reduction interface. The pyrite size distribution, DOP, Fe and S correlation points to an organic matter limited environment, where the main sulphur sink is pyrite rather than organic matter. The DOP and Fe/Al indicated that the sediments became anoxic at the sediment-water interface (early diagenetic stages). V/Cr assessment of the dolomite concretions suggested partially oxygenated environment corresponding to the black shale deposition. The occurrence of concretions at the base of the Whitehill Formation, which has the highest TOC content of 14% compared to other associated formations, is evidence that organic matter preservation was important to their origins. The parameters used here to assess the redox conditions of the black shales and the dolomite concretions in this region of the Karoo Basin suggest a normal marine redox environment, rather than the anoxic Black Sea-type environment. The conditions that affected the lower Ecca formations varied from semi-oxygenated to oxygen depletion environment. The oxygen depletion environment occurred during the deposition of the Whitehill Formation of which organic matter preservation was favoured..

  • Description: The purpose of this research was to investigate the reasons for non-adherence to the ISP and to measure the current level of adherence to the ISP. The research revealed that non adherence to the ISP is caused by lack of training or awareness, and through non-communication of the ISP to employees. The study was conducted at Capricorn District Municipality, Polokwane Local Municipality, Molemole Local Municipality and Blouberg Local Municipality. A web-based questionnaire (QuestionPro) was developed and it was directed to every official who uses or interacts with municipal information, to quantify the level of adherence to ISP by employees. An email with the questionnaire link administered by www.questionpro.com was then sent to the population of 152 employees. Presently ISP adherence is one of the key concerns that are faced by organisations. Employees are perceived as one of the reasons that there are security breaches within organisations; hence, it is of paramount importance that these security breaches are noticed, as well as technical matters. Most researchers have reasoned that non-adherence to ISP is one of the major challenges faced by organisations. The non-adherence to ISP will lead to potential information security threats and unauthorised access to information that might compromise municipal business operations. The Information Security Officer together with the help of management must educate employees regarding the value of IS and why it is crucial to adhere to these policies. The proposed strategy summarises the various concepts required in the promotion of awareness and adherence to an effective ISP. Ultimately, this research study concludes that if management continually trains employees, raising awareness about ISP and monitoring their adherence to ISP, this should increase the adherence level.

  • Description: The research was conducted to contribute towards the knowledge base on the potential for geothermal energy in the Soutpansberg Basin, located in the Limpopo Province of South Africa. The focus area was Siloam, an area that hosts a hottest spring with the highest recorded temperature of 67.5°C. The research involved visits to the Soutpansberg Basin, water sampling, carrying out ground geophysical surveys, and high-level processing of airborne magnetic data to determine depths and temperatures of magnetic sources. The water samples from the hot springs were found to be enriched in sodium, bicarbonate and chlorine with very low concentrations of other element species. The chemical composition of the spring water indicated a source chemistry comprising of the Na-ClHCO3 water assemblage that is a typical signature for deep circulating groundwater of meteoric origin. The circulation depth was inferred to be 2.0 km. The increased resolution of the ground magnetic, electrical resistivity tomography, and electromagnetic conductivity methods data made it possible to delineate subsurface structures at the spring such as dykes, sills, faults and fractures from generated depth models. Modelling of ground magnetic data showed that the Siloam hot spring occurred between two interpreted north dipping dykes approximately 150 m apart. The minimum depth extent of the dykes was interpreted to be 650 m. The magnetic susceptibility values determined from rock measurements and modelling of magnetic data indicated the presence of volcanic and metamorphic rocks. Electromagnetic profiling data showed that there were three main high conductivity zones in the study area with values above 100 mS/m; A central zone associated with the spring; A zone to the south of the spring and a north zone associated with the Siloam Fault. Ground geophysics survey results confirmed the existence of the Siloam Fault. Two artesian boreholes with water warmer than 40 °C were identified to the south of the Siloam hot spring. Both electromagnetic conductivity and electrical resistivity tomography surveys delineated lateral and vertical variation in the bedrock to depths of 40 m to 60 m. Water bearing structures that could be faults, or fractures were identified. Layering due to weathering and water content was found to be in the depth range of 20 m to 40 m. The depths of the potential heat sources were computed from the radially averaged power spectrum of airborne magnetic data for square blocks with side dimensions L of 51 km, 103 km, and 129 km. Spectral analysis based approaches namely Centroid method, Spectral peak method, and the Fractal based approach were used for computing depth and temperatures to heat sources. Airborne magnetic data sets with larger window sizes were preferred for depth computations, as they preserved spectral signatures of deeper sources and reduced the contribution of shallower sources. The size of the data windows did not have a marked effect of depth and temperature values. Shallower magnetic sources depths of approximately 2.0 km were delineated using the Euler deconvolution method. An anticlinal feature at depths of 2.0 to 4.5 km was 4 Final Submission of Thesis, Dissertation or Research Report/Project, Conference or Exam Paper delineated in the central part of the basin. Spectral analysis results indicated that the depth to the top of magnetic sources was at 3.5 km to 6.2 km; the centroid of the basement at 7.92 km to 13.41 km, and the basal below 11.09 km and 14.08 km. The lower end depth spectrum was determined from application of the Centroid method with the deeper being results from the Fractal based approach. The Spectral peak method was useful for determining the depth to the top of magnetic sources. The temperature of the top of magnetic sources and basement centroid were computed to be in the range 234.00 °C to 281.34 °C. Magnetic source depths and basal temperatures that were in the Curie point range within which rocks lose magnetism due to heat were determined, using a computation approach that utilised fractal parameters, to be 21.39 km and 577.42 °C, respectively. Increasing the value of the fractal parameter β from 0 to 4, had an effect of retaining deeper depths and higher temperatures. The fractal parameter β range of 3 to 4 that gave the Curie point parameters indicated basal rock types with an igneous predisposition. The research highlighted evidence for the existence of the Soutpansberg Basin Geothermal Field (SBGF). The area around Siloam is a potential target for drilling exploration geothermal energy boreholes based on the occurrence of hot springs, shallow heat source depths, anticlinal structure, high formation temperatures, deep circulating water and the achieved Curie point temperature.

  • Description: Data Quality (DQ) in Electronic Health Records (EHRs) is one of the core functions that play a decisive role to improve the healthcare service quality. The DQ issues in EHRs are a noticeable trend to improve the introduction of an adaptive framework for interoperability and standards in Large-Scale Databases (LSDB) management systems. Therefore, large data communications are challenging in the traditional approaches to satisfy the needs of the consumers, as data is often not capture directly into the Database Management Systems (DBMS) in a seasonably enough fashion to enable their subsequent uses. In addition, large data plays a vital role in containing plenty of treasures for all the fields in the DBMS. EHRs technology provides portfolio management systems that allow HealthCare Organisations (HCOs) to deliver a higher quality of care to their patients than that which is possible with paper-based records. EHRs are in high demand for HCOs to run their daily services as increasing numbers of huge datasets occur every day. Efficient EHR systems reduce the data redundancy as well as the system application failure and increase the possibility to draw all necessary reports. However, one of the main challenges in developing efficient EHR systems is the inherent difficulty to coherently manage data from diverse heterogeneous sources. It is practically challenging to integrate diverse data into a global schema, which satisfies the need of users. The efficient management of HER systems using an existing DBMS present challenges because of incompatibility and sometimes inconsistency of data structures. As a result, no common methodological approach is currently in existence to effectively solve every data integration problem. The challenges of the DQ issue raised the need to find an efficient way to integrate large EHRs from diverse heterogeneous sources. To handle and align a large dataset efficiently, the hybrid algorithm method with the logical combination of Fuzzy-Ontology along with a large-scale EHRs analysis platform has shown the results in term of improved accuracy. This study investigated and addressed the raised DQ issues to interventions to overcome these barriers and challenges, including the provision of EHRs as they pertain to DQ and has combined features to search, extract, filter, clean and integrate data to ensure that users can coherently create new consistent data sets. The study researched the design of a hybrid method based on Fuzzy-Ontology with performed mathematical simulations based on the Markov Chain Probability Model. The similarity measurement based on dynamic Hungarian algorithm was followed by the Design Science Research (DSR) methodology, which will increase the quality of service over HCOs in adaptive frameworks.

  • Description: The University of Fort Hare Alice campus experiences high crime rates. To address this problem, and add to the literature, this study applied the Crime Prevention through Environmental design (CPTED) model to measure the effectiveness of the crime prevention strategies at the University of Fort Hare (Alice campus). The aim of this study was to evaluate the sufficiency of surveillance and visibility, target hardening, maintenance and management at the University of Fort Hare, which contribute to the reduction of criminal activities around campus. The study further sought to evaluate the perceptions of students regarding their safety on campus by way of soliciting their experiences and observations. This study used the quantitative method, and questionnaires were distributed to the students in the Alice campus to collect data. The study found that whilst a marginal majority of students felt safe, a large proportion of students felt unsafe on campus. The study also found that students were dissatisfied with the service and found the security officers to be incompetent and un-trained. The study evaluated the sufficiency of crime prevention measures implemented within the university. One crucial aspect that emerged from the study is that CPTED principles were not sufficiently implemented to their fullest and the perception of the majority of students was that security personnel were not functioning in the way that they should, and measures such as adequate lighting were lacking. As a result, students felt unsafe on campus, especially during the night .The study concluded that there are clear increased feelings of vulnerability among students at the University of Fort Hare. The measures that are currently in place are not sufficient; therefore there is need for implementation of CPTED principles. It was recommended that the University increases number of CCTV surveillance cameras on campus, Social gathering places be surrounded by security guards for patrols, lighting recommendations that are modern and in proper design, keep up with repairs, make necessary replacements, paint, trim, current campus buildings e updated to meet recent CPTED practises etc.

  • Description: Long-term strategies for private-land conservation are experiencing a surge in scholarly attention. This interest is timely and justified. Globally, many important biodiversity values occur on private lands and are therefore subject to private land use decisions that can threaten their persistence in the absence of protection. Public and private actors spend billions of dollars annually to ensure the long-term protection and enhancement of public ecosystem services on private lands. Many governments recognize and strengthen “privately protected areas” (PPAs) as part of long-term protection obligations under the Aichi Biodiversity Targets (Stolton, Redford, and Dudley, 2014). As public policy makers deliberate over the best strategies to enhance private-land protection, they need to understand how cost-effective these different policy options are, and how they compare to each other.

  • Description: This paper explores climate as variable natural forces driving seasonal cycles1 that many African cultures had adjusted themselves to within intergenerational knowledge practices of longue durée. The study points to the need to re-orientate and expand climate science education so that it is centred on the seasonal cycles and intergenerational learning to better align transitioning to future sustainability with these in our southern African contexts of climate change today. The narrative touches upon historical accounts of knowledge practices amongst the Krobo, Bemba, Shona, Zulu and Xhosa, briefly pointing to how each, as an African culture, is situated as a social-ecological entity within the climatic tapestries of our African landscapes. It takes note of how cultural articulation within the seasonal cycles of regional climate have a long history with adaptive change in some contexts in more recent times. The review suggests that our learning in relation to emerging climate change should be informed by these histories of intergenerational knowledge practice. It notes how a better grasp of these could be important drivers of a widening cultural response to the changing dynamics in our climatic surroundings today. The brief study suggests that southern Africa is a special place with many unique and interesting climatic processes and associated socio-ecological systems and practices. These can provide engaging perspectives for informing education to mitigate or adapt to climate change. Here, a situated exploration of seasonal cycles can draw on both the latest in modern climate science and the rich social-ecological heritage of Africa briefly touched upon in the study. A model of process is offered for how both can be used in a seasonal cycles approach climate change education. This better situated and more inclusive approach can enable us to contemplate how we might best adjust our social-ecological dispositions and practices in the changing world that we all share.

  • Description: For most rare marine species, abundance trends are poorly estimated. This uncertainty often translates into disagreement on management regulations, impeding conservation efforts when they are most urgently required. The world’s largest sea bream, the red steenbras Petrus rupestris, has undergone a substantial and widely acknowledged decline during the 20th century. Standardised probability of encounter over the last 3 decades was used to track red steenbras abundance trajectories in 2 regions, which together represent the species’ distribution. The results predicted a reduction in abundance of 44% in the East region and 96% in the South-West region, from what was already considered to be a collapsed population at the start of the time series. The species is now largely confined to areas in the centre of its historical abundance. Content analysis of a recreational angling magazine revealed a concurrent 50% decrease in reported size between 1984 and 2012. Shore-based observer data (2009-2010) indicate that the impact of recreational fishers on this species far exceeded that of commercial fishers at the time. Regulations in the form of progressively more stringent catch and effort restrictions appear to have been largely ineffective, too lenient, implemented too late or were unsuitable to control fishing mortality for this species. This study highlights 2 fundamental challenges in management of rare marine fish species: (1) providing decision makers with a credible measure of abundance for species whose rarity limits data availability and (2) implementing effective policy changes before the specific measures become ineffective and obsolete.

  • Description: The main aim and objective of the study was to conduct an evaluation of Performance Management and Development System with reference to South African Social Security Agency Eastern Cape Regional Office. In order to achieve the objective, the study applied stratified random sampling to draw a sample of 44 participants and 4 key informants representing the four PMDS Moderation Branch Committees. The study utilized questionnaires and semi-structured interviews as data collection instruments. Data analysis was conducted using descriptive statistics in terms of frequencies and percentages of occurrences. Data was also analyzed using thematic content analysis and a number of themes were identified. The main findings of the study, were that there was alignment of individual key performance areas to their unit’s Operational Plan and ultimately to goals and objectives of the Agency. There was lack of performance feedback sessions between supervisor and supervisee, which resulted in training of employees not being conducted. PMDS Moderation Committee members were not equipped in terms of how to assess employee performance. The main recommendation of the study is for the Human Capital Development unit as custodians of the implementation of PMDS, to conduct regular workshops on the application of the PMDS Policy for the employees as well as training of the PMDS Moderation Committee members. This would be done in an effort to ensure that the implementation of PMDS leads to the achievement of the goals and objectives of the Agency. The implementation of the PMDS Policy at SASSA Eastern Cape Regional Office has the potential to contribute to improved service delivery and by implication, the improvement of the quality of life of the millions of the recipients of social grant.

The objectives of the study were to find out the extent to which records management is practised; to find out what records management programme exist; to find out the infrastructure available for records management; and to identify the challenges, if any, facing records management in Albany Museum. The records life cycle and the records continuum formed the theoretical framework. The study adopted qualitative and quantitative research approaches. The state accountant, senior administrator, fossil excavator, receptionist and the postgraduate researcher formed the sample of the study. Quantitative data were coded and analysed using Microsoft Office Excel 2013 while the qualitative data were analysed using thematic analysis. The major findings showed that records management Albany Museum is very weak, which makes it difficult for the museum to derive or benefit from effective records management as well as experiencing delays in decision-making, loss and misplacement of records. Also, it was revealed that there was no personnel responsible for the records management. The study recommended for recruitment of personnel for records management in the museum to improve on records management as well as the development of a functioning records management program

  • Description: This study examines the nature of the United States intervention in Somalia, specifically the use of drone strikes that first targeted the militant Sunni Islamist transnational group, al-Qaeda, which claimed responsibility for the 11 September 2001 attacks on the United States, and now target the Somali organisation, Harakat al-Shabaab al-Mujahidin, commonly known as al-Shabaab. The use of drone strikes in the US led war on terror has raised concerns about sovereignty as the extra-judicial killings are conducted without the consent of the concerned states. Furthermore, drone strikes also raise questions about the processes of liberal intervention as the US conducts them without the approval of the United Nations Security Council. It is argued in this study that what is understood to be the “golden era” of liberal interventionism is a legacy of the post-Cold War unipolar dominance of the United States in global governance and security. It is argued that US unipolarity was accompanied by a shifting perception regarding the security position of weak states, whose weakness becomes understood as a source of global insecurity. This perception that so called “weak” and “fragile” states are sources of threats is a departure in International Relations theory, because the discipline is historically preoccupied with studying the actions of powerful states and their consequence for the global order. It is argued that the discourse on the war on terror, and its focus on “failed states” as breeding grounds for alleged terrorists, represents the height of the repositioning of less powerful states from a peripheral status in IR analysis and practice, to their current position that are now being represented as core sources of threat to international peace and security. Through life history interviews with Somali nationals in Grahamstown, Port Elizabeth and Uitenhage, South Africa, the study examines the consequences of US actions from the eyes of Somali people. The findings of this study show that despite all the controversy surrounding the legitimacy of the war on terror, the manner in which it is conducted, as well as the tactics that it employs, the majority of Somali participants showed an overwhelming support for the US intervention. Participants expressed support for the US extra-judicial killings because they are understood to undermine al-Shabaab strength which is a major source of insecurity. The study also shows that the lack of necessary collaboration between the US intelligence and the Somali ground forces has resulted in high numbers of civilian deaths, which participants fear can be used by al-Shabaab to recruit and radicalise more Somalis. The study also shows that most Somalis resent the presence of the African Union Mission in Somalia because Kenya and Ethiopia are seen as 10 pursuing national interests that are not invested in Somali peace and stability. The study concludes that US extra-judicial killings have failed to constrain the actions of al-Shabaab. Somalis expressed that the leadership of current president, Mohamed Abdullahi Mohamed Farmaajo, holds the unique possibilities of creating national unity that rises above clan divisions and the radical Jihadist ideology of al-Shabaab.

  • Description: The study examines four curriculum documents with regards to curriculum facets, further interrogated through indicators for certain facets in order to ascertain whether the documents could be considered to be educative. Comparison is made with selected resources internationally. Observed episodes in four mathematics classes are interrogated with regards to teacher facets and concomitant indicators, to assess whether the tenets proposed in the written curriculum are translated into practice in the classrooms. The four Grade 3 teachers are interviewed about their views on the curriculum, their views on teaching and their views on their own agency in teaching mathematics. The teachers’ complete selected examples from a Mathematics Knowledge for Training (MKT) questionnaire and are engaged in conversations about iii their beliefs about mathematics and their confidence in both doing and teaching mathematics. The study identifies that the current CAPS curriculum documents focus on mathematical content almost exclusively and give minimal guidance concerning pedagogical content knowledge. The agency of teachers is not addressed. The study suggests a three-dimensional model of curriculum design that encompasses new educative curriculum materials; guidance on innovative teacher practices and direction towards new beliefs in teachers which could build agency and confidence. The concern that this study uncovers is that although the school and teachers were specifically chosen to minimise linguistic and social detractors, the intended curriculum does not appear to have been universally translated into

  • Description: The role and the impact of leadership in business and society is a topic of interest to many in business. This is evident by the increase in the number of studies on the topic of leadership. Organisational leaders are responsible to oversee the company’s operations including the allocation of resources, people management and to facilitate process integration to enable the organisation to achieve its stated objectives. State-Owned Enterprises (SOEs) such as Eskom has a mandate to provide infrastructure services to improve the country’s economic conditions. In particular, Eskom is responsible for electricity generation, transmission and distribution in South Africa and other neighbouring counties. Infrastructure development is much needed in South Africa (SA) to enable the country to attract investors and to grow local businesses, as its economy was downgraded to one notch above‘junk status’ in June 2017 (Mutize & Gossel, 2017). Apart from social responsibility, SOEs are required to operate efficiently in line with good corporate governance and become self-sufficient to fund their own future growth plans. Hence, the importance of SOEs to improve their own performance and efficiencies. In the past few years, Eskom has underperformed in meeting its key deliverables as stipulated in the shareholder compact. These include the electrification of households, maintenance of the current infrastructure and the building of excess electricity capacity. The poor performance has negatively affected the country economy due to planned outages when trying to balance electricity demand and supply. It has further contributed to ongoing community service delivery protests, which costs the country millions of rands (Kekana, 2017; Nyembezi, 2015). In the same period, the company faced many leadership changes which partly contribute to its not fully implementing its strategic plans. The objective of this study was to contribute to a possible improvement in Eskom’s performance by examining the influence of leadership on organisational performance, using the independent variables of the leadership conduct (authenticity), work support and performance determinants (culture, communication, change management, strategy implementation and talent management) and further to add to the current literature in explaining how leadership influences performance. The research design was positivistic asthe relationship amongst the above-mentioned variables was statistically tested. The sample consisted of 111 managerial and non-managerial employees in Eskom, across the nine provinces in South Africa. The empirical results were reported and interpreted. The results revealed that the talent management process, work support, effective communication and strategy implementation have a positive influence on employee performance, which in turn has a positive influence on organisational performance. These results were discussed in terms of the implications they hold for the leadership at Eskom. The limitations are reported, thereby providing areas for possible future research.

  • Description: The purpose of this study was to investigate the strategies schools use to maintain discipline in a low socio-economic area. Poor discipline in public schools has become a major concern following the abolition of corporal punishment by the National Department of Education. The educational authorities left educators in schools with no constructive alternatives to maintain discipline and alternative strategies had to be found and implemented. Data were collected be means of semi-structured interviews, from principals, educators and school governing body (SGB) members. Three neighbouring high schools in the Northern Areas of Port Elizabeth in the Nelson Mandela Bay District of Education were used. A qualitative research approach was employed in the study. The findings supported the literature that was consulted in that there is a wide range of causes of disciplinary problems in schools. According to the findings, there is a lack of effective strategies to maintain discipline in schools but Bronfenbrenner’s ecological systems theory is in line with the perceptions of the respondents in this study. This study opened a door for further research into effective strategies that are in line with the changing teaching environment in low socio-economic areas. The government should come on board to create an environment to promote the good life for educators and learners. The final outcome of this study focused on strategies that principals, educators and SGB members can use to maintain discipline in low socio-economic areas. These strategies can create an environment that is conducive for teaching and learning, especially in schools situated in low socio-economic areas. These include consistency, parental involvement, detention, suspension and the home environment and socio-economic circumstances. Learners must be disciplined and parents must be involved in the maintenance of discipline in schools situated in low socio-economic areas.

  • Description: This case study was conducted in a small rural community called Mpembeni, in South Africa’s KwaZulu-Natal province. It was motivated by my observation of high levels of competence in ‘cattle knowledge’ amongst children coupled with a simultaneous failure at school. I view schools as integral parts of the community and consider them as being influenced by the community, which they in turn influence. This study set out to understand that which embodied informal learning in home/pasture-based contexts as well as formalised learning processes in schools. I used Sociocultural theory as the most congruent of educational theories to surface and illuminate the intergenerational learning processes that were taking place in the area. This warranted my use of research investigation methods that could, in non-intrusive ways, expose the everyday community practices that related to cattle as a particular medium of cultural expression. Ethnography, sourced from anthropology, aided by ethnomethods, was not only compatible with my study and the way in which I wanted to write out the research report, but also with my educational theory and its counterhegemonic intents. To understand the colonialities that framed the discord that embodied home and school as learning contexts, I used postcolonial theory, not only as a lens but as a counterhegemonic response. This theory also informed my research methodology as well as afforded me the reflexivity tools for an examination of my own intergenerational learning and the relational identities of myself as ‘Other’ in the lives of the research participants. It further facilitated the exploration of the potential for potential hybrid third spaces within the bubbling meeting nodes of the socio-cultural context of school and home/pasture based settings of learning. I observed cattle herding related practices, interviewed children, their parents and/or carers, dipping tank managers, livestock inspectors, community elders and members. I also analysed some of the written and unwritten content that made up the formal and informal based learning processes and reviewed some of the most recent South African Curriculum Statements and related texts on the representations of cattle. I sought views from teachers on their interactions with the people of Mpembeni, whose children they taught. I also explored axes of tension, silences and presences on anything related to cattle in schools. I argue and make a case for the development of thought by African scholars to advance Africa’s education rather than aid mimicry and the importation of theories of little congruence and relevance to the African context and Africa’s future. The study has made some contributions to new knowledge. This is in its exploration of sociocultural intergenerational methods and techniques that are employed for learning in community contexts, highlighting the importance of surfacing and understanding of children’s knowledge and experiences. The study has gone further to deliberate the in-betweenness of school and home learning environments, highlighting and unsilencing silenced, peripherised, new, old, considered irrelevant in the past, context and time congruent and liberatory knowledges. I propose that the knowledges located in these cleavages of difference be utilised to transform and create learning bridges between home and school environments. I propose that those ways of knowing that see others as nothings, be exposed and unlearned. Methods of learning that naturally unfold at home could be replicated at school with a recognition of the intergenerational methods, techniques, practices and the learning values in a critically constructive manner that narrows difference and othering.

  • Description: Limited research exists, both internationally and in the South African context, on the use of basketball as tool for youth development through sport. In almost all sport-based youth development programs, the desired sport is football and occasionally rugby. Developing the youth is crucial for the development of a nation and the United Nations has highlighted the progress sport has had as a development tool over the past 20 years. South Africa has recently received international acclaim by becoming the focal point of the National Basketball Associations (NBA) presence in Africa by hosting the last three NBA Africa games. South Africa’s Eastern Cape province was the home of elite basketball in the early eighties and is no stranger to the sport of basketball. The study aimed to explore the possibility of using basketball as a tool for youth development in Nelson Mandela Bay in the Eastern Cape. The study employed a mixed methods research approach that was explorative, descriptive and contextual in design. The empirical data was collected by means of a questionnaire distributed to target basketball players in the Nelson Mandela Bay area. While the data analysis and literature favoured basketball as a suitable tool to be used in sport-based youth development programs, there were limitations with respect to the number of female participants in the study. It was recommended that further research be considered within this field of study and on a wider scale, in an effort to expand the knowledge base on youth development through basketball across South Africa.

  • Description: Commercial drivers have been identified as eliciting behaviours that promote non- communicable diseases and road traffic accidents. The aim of the study is to determine the prevalence and pattern of alcohol use, smoking and physical inactivity among commercial taxi drivers in Buffalo City Metropolitan Municipality, South Africa. A cross-sectional study was conducted among 403 commercial drivers using the face-to-face interviews method. The WHO STEPwise questionnaire was used to obtain the demographic data, self-reported rate of alcohol consumption, tobacco use and physical inactivity. The participants’ mean age was 43.3 ± 12.5 years. About 30% of the participants were daily smokers, 37% consumed alcohol regularly and only 18% were physically active, whilst 82% were physically inactive. The prevalence of alcohol use, smoking and physical inactivity is high among commercial drivers in East London. Workplace health education on the health effects of these lifestyles’ risky behaviours on individuals and the general public should be given to the drivers.

  • Description: The study investigates the Archives and Records Management Programmes (ARMP) in the University of Fort Hare (UFH) and Rhodes University (RU). The task of managing huge quantities of records and archives material is not an easy task when people have to use limited resources. The Research Objectives of the this study was to find out types of records created, received and maintained by university archives and records management programmes at University of Fort Hare and Rhodes University.  Establish the available infrastructure for ARMP at the UFH and RU.  Find out the legislative and regulatory frameworks that govern the ARMP at the UFH and RU.  Identify challenges if there are any facing ARMP at the UFH and Rhodes University. Interviews and questionnaires were two research instruments used in this study to collect data; additional data was collected by reading relevant documents gathered on both institutions and on their website. In this study, the sample was 26 respondents from both universities. The study dealt with administrative staff who deal with records management: Records managers/Officers and Archivists at both institutions. viii Data collected was coded and analysed using Statistical Package for Social Sciences (SPSS) and the findings were presented using pie chart , graphs. The triangulation approaches involves using more than one method to collect data and it is a way of assuring the validity of research with variety of methods to collect data. Findings revealed that respondents were unaware of ARMP in the university. And also some of the findings were the infrastructural needs such as the Lack of records storage, space, Records Preservation facilities (RH, Light), Personnel Training and Development. The challenges facing ARMP in universities includes: a lack of programmes to manage records and archives material, absence of policy that regulates archives and records keeping in the universities understudy, the existing infrastructure at hand cannot meet the requirements for regulatory framework on records and archives management. Based on these challenges mentioned above, the study recommended that both institutions should improve their infrastructure as to be able to preserve the archival material. Training and retraining of staff among others should include use of technology, filing, records creation, maintenance and disposition
