- Description: The studies described in this thesis, as far as could be ascertained, were the first to investigate the physiological and mechanistic characteristics of all-out running using the critical speed concept specifically applied to field-sport athletes. In the first study the oxygen uptake (𝑉̇𝑂2) kinetics of linear and shuttle all-out running were investigated. The 𝑉̇𝑂2 kinetic parameters were also related to parameters derived from a graded exercise test. No differences were observed in all 𝑉̇ 𝑂2 kinetic parameters between all-out linear and shuttle running, even though differences in all-out testing parameters were evident. The study was novel in that it was, as far as could be ascertained, the first to implement and investigate differences in 𝑉̇𝑂2 kinetics applied to all-out running. The second study investigated whether the parameters derived from all-out linear and shuttle running were representative of aerobic fitness, and the extent to which the all-out test (AOT) related to already established evaluations of aerobic fitness (e.g., graded exercise test [GXT] and the Yo-Yo intermittent recovery test [YYIR1]). It was also investigated whether the parameters from the AOTs could be used to predict the time to completion (tLIM) of shuttle-based performances. The outcomes of this study showed that both the linear and 50-m AOTs were indeed valid for the aerobic assessment of fitness by showing high correlations with maximal pulmonary oxygen uptake (𝑉̇𝑂2𝑚𝑎𝑥). Both the linear and 50-m AOT could therefore be used as surrogates for the evaluation of aerobic fitness. Interestingly, in terms of the tLIM prediction, the 25-m AOT showed the greatest utility. This study was novel on several fronts in that it was the first to: (1) investigate the physiological link between linear and shuttle AOTs and the GXT, (2) investigate the difference between AOTs and the YYIR1, and (3) investigate the application of the AOT methodology to field-based athletes such as rugby players. The third study investigated the energetic cost (EC) of locomotion as well as the metabolic power (𝑃̇) required to run at given speeds. The energetic approach provides a more robust evaluation of the differences between linear and shuttle running due to the all-out nature of the tests. Conventional methods of energy assessment often fall short due to the preclusion of a physiological steady-state, hence requiring more robust mathematical models to evaluate all-out running performance. The results of this study showed that differences between linear and shuttle AOTs are more likely neuromuscular as opposed to physiological. Peak EC and 𝑃̇ were significantly greater for shuttle running compared to linear running, showing clear non-linear increases with each successive increase in running speed. However, the mean EC and 𝑃̇ were not different, showing that all-out shuttle running ‘balances’ the lower running speeds (implying a lower physiological load compared to linear running) with the higher metabolic load imposed by the intense directional changes. This study was novel as it was, as far as could be ascertained, the first to apply the energetic approach to all-out running as well as investigate the differences in energetics between linear and shuttle AOTs. The fourth study provided a means by which the speed-time characteristics of all-out running could be objectively quantified. A novel bi-exponential model was applied to both the linear and shuttle speed-time curves and allowed various mechanistic aspects of the speed-time curve to be characterized. Conventional assessment of the AOT allows for the derivation of only two key parameters, namely critical speed (CS) and the finite distance achievable at speeds exceeding CS (D’). The application of the bi-exponential model expands the number of useful parameters that can be derived from an AOT to seven. The additional useful parameters include: maximum speed [𝑆𝑚𝑎𝑥], time to maximum speed [𝑡𝑐], amplitude of the difference between 𝑆𝑚𝑎𝑥 and CS [𝐴𝑑], curvature constant of the exponential decay [𝜏𝑑] and the asymptote of the exponential decay function [𝑆0], fatigue index showing the percent decline between 𝑆𝑚𝑎𝑥 and CS [FI%], and the finite capacity for running at speeds exceeding CS [D’; representing the area under the curve that is above CS]. The CS and D’ parameters derived from the bi-exponential model were not different to the CS and D’ parameters derived using the conventional method of analysis, thereby showing that the bi-exponential model is a valid means of assessing the curvature characteristics of the AOT, as well as providing additional information that cannot be gleaned from the traditional approach.

- Description: Due to generational differences in organisations, it is sensible to determine the learning preferences of professional employees across generations so that organisations can provide learning opportunities that these employees will embrace. The purpose of this study was therefore to determine the personal development preferences of professional employees from different generations within corporate organisations in Cape Town. The research intends to aid organisations that upskill their employees and to ensure they are utilising the most effective and efficient methods. To this effect, a survey with a self-administered questionnaire was provided to 59 professional employees across several generations utilising a Likert scale where the participants were able to rate the different developmental strategies based on their preferences. The results revealed that similarities existed between the generations in relation to their preferences; however, younger generations were more likely to be open to several personal development strategies, whereas older generations had a refined preference they have developed over the years. It is consequently recommended to organisations to customise their training methods to the different generational groups, based on their preferences and thereby to use this method to aid professional employees in understanding each other.

- Description: Citrus sinensis, Citrus reticulata and Citrus clementine are citrus species that belong to a large family Rutaceae. Citrus leaves and peels are often regarded as waste products. In view of the environment pollution impact, the search for end use of citrus waste products for economic value and medicinal purposes was sort after. The aim of this study was to investigate chemical composition of citrus waste products (leaves and peels) essential oils and determine biological active volatile compounds from Citrus sinensis, Citrus reticulata and Citrus clementine Leaves and peels of Citrus sinensis, Citrus reticulata and Citrus clementine collected twice from citrus farm were extracted for essential oils using hydrodistillation method and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) for plant samples collected in 2016 and, gas chromatography (GC) and gas chromatography-triple quadrupole-mass spectrometry (GC-MSMS) for plant samples collected in 2017. The oil yield for Citrus sinensis was 0.19 - 0.85 %v/w for fresh and dried leaf and peels for samples collected in 2016 and 0.26 – 0.87% v/w for those collected in 2017. Analysis of the essential oils analyses identified sabinene (20.4% GCMS, 22.6% GCMSMS), terpinen-4-ol (13.2% GCMS, 6.8% GCMSMS) and linalool (7.6% GCMS, 19.3% GCMSMS) as major compounds in fresh leaves essential oils while β-elemene (16.3% GCMS, 21.4% GCMSMS) and sabinene (10.7% GCMS, 20.8% GCMSMS) were major compounds characterized in dried leaves essential oils. Fresh and dried peels essential oils had limonene as the major constituent (49.6% GCMS, 87.1% GCMSMS) and (73.6% GCMS, 88.3% GCMSMS) respectively. Citrus reticulata essential oils percentage yield range between 0.44-0.80% v/w for fresh and dried leaf and peel oils. Analyses of the GCMS and GCMSMS chromatogram of the volatile oils analyses revealed linalool (33.4% GCMS, 19.6% GCMSMS), (+)-spathulenol (15.2% GCMS, 10.1% GCMSMS) and terpinene-4-ol (4.5% GCMS, 11.9% GCMSMS) as major compounds in fresh leaf essential oils while, sabinene (20.8% GCMS, 32.5% GCMSMS) and linalool (17.2% GCMS, 20.4% GCMSMS) were the major compounds found in dried leaf essential oils. Limonene (55.2%, 75.4% GCMS; 39.5%, 80.8% GCMSMS) was the major prominent compound identified in the C. reticulata peel essential oils in fresh and dried peels respectively, followed by linalool (12.8%, 2.9% GCMS; 48.4%, 7.4% GCMSMS). Percentage yields for the essential oils from C. clementine fresh and dried leaves and peels ranges from 0.40-0.62% v/w for. Fresh and dried leaves volatile oils had sabinene (22.7-27.1%) for GCMS and GCMSMS respectively), linalool (18.5- 20.9% GCMS and GCMSMS) and terpinene-4-ol (6.5- 11.8% GCMS and GCMSMS) as main compounds while fresh and dried peels oils were dominated by limonene (38.9- 86.5% GCMS and GCMSMS). Phytochemical screening experiment of the three citrus species leaves and peels aqueous extract reveal the prominent presence of flavonoids and phenolic compounds in high concentrations. C. reticulata and C. clementine peels and leaves volatile oils exhibited higher antioxidant activity as DPPH free radical scavengers and Ferric reducing power (FRAP) ability, when compared to C. sinensis essential oils which exhibited minimum antioxidant activity. Antioxidant activity of leaves and peels essential oils maybe due to the presence of oxygenated monoterpenes and high limonene content. C. sinensis peels oils showed non-toxic to extremely very low toxicity effect at highest dose 2000 mg/kg. C. reticulata and C. clementine peels oils showed toxicity effect in mice at high dose levels. It is suggested that citrus volatile oils could be safe to use at lower dose levels. Citrus species peels and leaves volatile compounds limonene linalool and sabinene exhibited antiinflammatory activity by significantly reducing rats paw oedema size induced by fresh egg albumin. The study suggests the use of Citrus waste products (leaves and peels) as natural antioxidants with antiinflammatory properties for medicinal value and volatile oils compounds for aroma in beverages and cosmetic industries.

- Description: The store industry is globally the main distribution channel for grocery items to reach final consumers. Specifically for South Africa and Zimbabwe the store industry greatly contributes to the countrys economic growth. However, increasing competition in developed countries has forced store chains with a competitive edge in terms of promoting their brands and building market share such as Walmart and Spar to expand into the growing African market. Concomitantly, growing African store chains such as Choppies of Botswana are moving into new African markets such as South Africa and Zimbabwe. Following this increasing competition, Pick n Pay a leading store chain in South Africa has responded by opening stores in African townships and other African countries such as Zimbabwe. This has resulted in Pick n Pay customers’ cultural diversity, and how to build and maintain market share through effective promotional and brand building strategies being areas of concern. Therefore the primary objective of this study is to determine the influence of Pick n Pay customers’ cultural orientations on their buying behaviour towards monetary- and non-monetary sales promotions and store equity in South Africa and Zimbabwe. From a comprehensive literature review, a hypothesised model was developed to determine the customers’ cultural orientations that might influence the buying behaviour towards monetary- and non-monetary sales promotions and Pick n Pays store equity in South Africa and Zimbabwe. Four customers cultural orientations were investigated namely, ubuntu/unhu, power distance, uncertainty avoidance and status consumption. This quantitative research approach study sought the perceptions of Pick n Pays customers on their cultural orientations, buying behaviour towards monetary- and non-monetary sales promotions and on store equity in South Africa and Zimbabwe. A survey was conducted with the aid of a structured hardcopy questionnaire, distributed via fieldworkers in both countries using a combination of convenience- and snowball sampling. A final usable sample of 500 respondents was obtained. The items in the questionnaire were validated by conducting exploratory factor analysis, where after the Cronbachs alpha values were calculated for each of the valid constructs to confirm inter-item reliability. Descriptive statistics in the form of frequency distributions was used to summarise the demographic profiles of the respondents and to describe the means and standard deviations of the valid constructs. The Pearsons product moment correlations revealed moderate correlations between monetary- and non-monetary sales promotions as well as non-monetary sales promotions and store equity in the full sample, and for the South African and Zimbabwean samples. Moderate correlation was also found in South African sample between Ubuntu ubuntu/unhu cultural orientation and non-monetary sales promotions. Multi-collinearity diagnostics testing was conducted prior to multiple regression analysis to confirm that there is no evidence of collinearity between the independent-, mediating- and dependent variables. The multiple regression analysis revealed eight statistical significant relationships between the independent-, mediating- and dependent variables for the full sample while for the South African and Zimbabwean samples four and nine were found respectively. Although the full sample and Zimbabwean sample had similar statistically significant relationships, the relationship between an uncertainty avoidance cultural orientation and store equity was unique to the Zimbabwean sample only. There was only a statistically significant relationship between a power distance cultural orientation and store equity for the South African sample. Structural equation modelling was used as the main statistical procedure to test for mediation in the study. Only two relationships found in the multiple regression analysis were not confirmed in the structural equation modelling results, namely the relationships between an confirmed in the structural equation modelling results, namely the relationships between an uncertainty avoidance cultural orientation and monetary sales promotions, as well as with non-monetary sales promotions. Six path relationships were confirmed in the structured equation modelling. These statistical significant path relationships were between an ubuntu/unhu- cultural orientation with monetary- and non-monetary sales promotions, as well as with store equity. A statistical significant path relationships were also found between a status consumption cultural orientation with non-monetary sales promotions and store equity. The sixth statistical significant path relationship was between non-monetary sales promotions and store equity. Furthermore, SEM confirmed full mediation of monetary sales promotions in the relationship between a status consumption cultural orientation and store equity. On the other hand, there were partial mediations of non-monetary sales promotions in the relationships between an ubuntu/unhu and status consumption cultural orientations with store equity. The SEM results also confirmed that the data fits the complete model. Multi-variant analysis of variance was carried out to determine if respondents’ demographic profiles influenced their cultural orientations and buying behaviour towards monetary-and non-monetary sales promotions. Post-hoc Scheffe tests identified sixteen statistically significant mean differences between the demographic data groups and the cultural orientation and sales promotions variables. Subsequently, the Cohens d analysis confirmed thirteen practical significant relationships, of which only three had large practical significance. Based on the MRA and SEM confirmed relationships, several suggestions are made. Ubuntu/Unhu and status consumption cultural orientations influenced buying behaviour towards non-monetary sales promotions. For ubuntu/unhu orientated customers, it is suggested that Pick n Pay keeps its non-monetary sales promotions open and accessible to most customers and sponsor more popular events such as competitions for baking, cooking and soccer. To target status consumption orientated customers, Pick n Pay should position its non-monetary sales promotions in line with their expectations such as promoting healthy living to appeal to its healthy conscious customers. Pick n Pay should also avoid making price the focal point when communicating to status consumption orientated consumers but rather focus on image building selling points such as store service. For ubuntu/unhu orientated customers, Pick n Pay should underscore the interdependence value in its communication of monetary sales promotions by offering monetary promotions with benefits for all family members. To entrench brand equity, Pick n Pay should engage ubuntu/unhu brand ambassadors from influential family members, friends and community groups such as church groups and provide after-sales service using 24hr customer service hotlines and social media to promote customer interaction any time of the day. Pick n Pay must consider entrenching the status consumption health conscious customers into interaction between themselves or the store through chatrooms or clubs to make sure they remain loyal to the store. It is recommended that Pick n Pay conduct non-monetary sales promotion by creating awareness campaigns for its organic and finest private brands in their Fresh Living Magazine so that customers have product knowledge and encourage them to become regular buyers. In-store distribution of product samples can also help build interest in the brands. Furthermore, employing data mining techniques on customer databases provided in Smartshopper and Rich Rewards loyalty programmes can help understanding specific target customer groups and developing target marketing campaigns. For status consumption orientated customers, Pick n Pay can incentivise the adoption of online shopping through sales promotions such as free delivery for first time shoppers. The store can also have personalised free rewards for its most loyal customers. For ubuntu/unhu orientated customers, it is recommended that Pick n Pay engage in corporate social responsibility that target the needy in the society such as donating to elderly and orphanages and request their customers to donate their loyalty points to charities of their own choices. It is suggested that Pick n Pay promote excellent service and a wide variety of quality products to ensure their status consumption orientated customers remain loyal to the store. They can also offer a suggestions box for these customers to make them feel heard. Their employees should be selected based on contemporary skills such as digital- and green marketing and healthy living product knowledge and they should train their current employees on these areas to enable addressing customers’ queries confidently. This study has added to scarce academic literature on customers’ cultural orientations, sales promotion buying behaviour and store equity in Africa in general. From the hypothesised model developed in this study, a significant contribution has been made in the body of knowledge on the influence of customers’ culture on buying behaviour towards sales promotions and store equity, especially in the retail field for stores such as Pick n Pay. This study was also the first to identify the major role demographics can play in customers’ cultural orientations and sales promotion buying behaviour. The recommendations can be useful to assist with developing marketing strategies suitable for any retail store such as Pick n Pay which wants to venture into African markets.

This has resulted in Pick n Pay customers’ cultural diversity, and how to build and maintain market share through effective promotional and brand building strategies being areas of concern. Therefore the primary objective of this study is to determine the influence of Pick n Pay customers’ cultural orientations on their buying behaviour towards monetary- and non-monetary sales promotions and store equity in South Africa and Zimbabwe. From a comprehensive literature review, a hypothesised model was developed to determine the customers’ cultural orientations that might influence the buying behaviour towards monetary- and non-monetary sales promotions and Pick n Pays store equity in South Africa and Zimbabwe. Four customers cultural orientations were investigated namely, ubuntu/unhu, power distance, uncertainty avoidance and status consumption. This quantitative research approach study sought the perceptions of Pick n Pays customers on their cultural orientations, buying behaviour towards monetary- and non-monetary sales promotions and on store equity in South Africa and Zimbabwe. A survey was conducted with the aid of a structured hardcopy questionnaire, distributed via fieldworkers in both countries using a combination of convenience- and snowball sampling. A final usable sample of 500 respondents was obtained. The items in the questionnaire were validated by conducting exploratory factor analysis, where after the Cronbachs alpha values were calculated for each of the valid constructs to confirm inter-item reliability. Descriptive statistics in the form of frequency distributions was used to summarise the demographic profiles of the respondents and to describe the means and standard deviations of the valid constructs. The Pearsons product moment correlations revealed moderate correlations between monetary- and non-monetary sales promotions as well as non-monetary sales promotions and store equity in the full sample, and for the South African and Zimbabwean samples. Moderate correlation was also found in South African sample between Ubuntu ubuntu/unhu cultural orientation and non-monetary sales promotions. Multi-collinearity diagnostics testing was conducted prior to multiple regression analysis to confirm that there is no evidence of collinearity between the independent-, mediating- and dependent variables. The multiple regression analysis revealed eight statistical significant relationships between the independent-, mediating- and dependent variables for the full sample while for the South African and Zimbabwean samples four and nine were found respectively. Although the full sample and Zimbabwean sample had similar statistically significant relationships, the relationship between an uncertainty avoidance cultural orientation and store equity was unique to the Zimbabwean sample only. There was only a statistically significant relationship between a power distance cultural orientation and store equity for the South African sample. Structural equation modelling was used as the main statistical procedure to test for mediation in the study. Only two relationships found in the multiple regression analysis were not confirmed in the structural equation modelling results, namely the relationships between an confirmed in the structural equation modelling results, namely the relationships between an uncertainty avoidance cultural orientation and monetary sales promotions, as well as with non-monetary sales promotions. Six path relationships were confirmed in the structured equation modelling. These statistical significant path relationships were between an ubuntu/unhu- cultural orientation with monetary- and non-monetary sales promotions, as well as with store equity. A statistical significant path relationships were also found between a status consumption cultural orientation with non-monetary sales promotions and store equity. The sixth statistical significant path relationship was between non-monetary sales promotions and store equity. Furthermore, SEM confirmed full mediation of monetary sales promotions in the relationship between a status consumption cultural orientation and store equity. On the other hand, there were partial mediations of non-monetary sales promotions in the relationships between an ubuntu/unhu and status consumption cultural orientations with store equity. The SEM results also confirmed that the data fits the complete model. Multi-variant analysis of variance was carried out to determine if respondents’ demographic profiles influenced their cultural orientations and buying behaviour towards monetary-and non-monetary sales promotions. Post-hoc Scheffe tests identified sixteen statistically significant mean differences between the demographic data groups and the cultural orientation and sales promotions variables. Subsequently, the Cohens d analysis confirmed thirteen practical significant relationships, of which only three had large practical significance. Based on the MRA and SEM confirmed relationships, several suggestions are made. Ubuntu/Unhu and status consumption cultural orientations influenced buying behaviour towards non-monetary sales promotions. For ubuntu/unhu orientated customers, it is suggested that Pick n Pay keeps its non-monetary sales promotions open and accessible to most customers and sponsor more popular events such as competitions for baking, cooking and soccer. To target status consumption orientated customers, Pick n Pay should position its non-monetary sales promotions in line with their expectations such as promoting healthy living to appeal to its healthy conscious customers. Pick n Pay should also avoid making price the focal point when communicating to status consumption orientated consumers but rather focus on image building selling points such as store service. For ubuntu/unhu orientated customers, Pick n Pay should underscore the interdependence value in its communication of monetary sales promotions by offering monetary promotions with benefits for all family members. To entrench brand equity, Pick n Pay should engage ubuntu/unhu brand ambassadors from influential family members, friends and community groups such as church groups and provide after-sales service using 24hr customer service hotlines and social media to promote customer interaction any time of the day. Pick n Pay must consider entrenching the status consumption health conscious customers into interaction between themselves or the store through chatrooms or clubs to make sure they remain loyal to the store. It is recommended that Pick n Pay conduct non-monetary sales promotion by creating awareness campaigns for its organic and finest private brands in their Fresh Living Magazine so that customers have product knowledge and encourage them to become regular buyers. In-store distribution of product samples can also help build interest in the brands. Furthermore, employing data mining techniques on customer databases provided in Smartshopper and Rich Rewards loyalty programmes can help understanding specific target customer groups and developing target marketing campaigns. For status consumption orientated customers, Pick n Pay can incentivise the adoption of online shopping through sales promotions such as free delivery for first time shoppers. The store can also have personalised free rewards for its most loyal customers. For ubuntu/unhu orientated customers, it is recommended that Pick n Pay engage in corporate social responsibility that target the needy in the society such as donating to elderly and orphanages and request their customers to donate their loyalty points to charities of their own choices. It is suggested that Pick n Pay promote excellent service and a wide variety of quality products to ensure their status consumption orientated customers remain loyal to the store. They can also offer a suggestions box for these customers to make them feel heard. Their employees should be selected based on contemporary skills such as digital- and green marketing and healthy living product knowledge and they should train their current employees on these areas to enable addressing customers’ queries confidently. This study has added to scarce academic literature on customers’ cultural orientations, sales promotion buying behaviour and store equity in Africa in general. From the hypothesised model developed in this study, a significant contribution has been made in the body of knowledge on the influence of customers’ culture on buying behaviour towards sales promotions and store equity, especially in the retail field for stores such as Pick n Pay. This study was also the first to identify the major role demographics can play in customers’ cultural orientations and sales promotion buying behaviour. The recommendations can be useful to assist with developing marketing strategies suitable for any retail store such as Pick n Pay which wants to venture into African markets.

- Description: Landscape stewardship offers a means to put social-ecological approaches to stewardship into practice. The growing interest in landscape stewardship has led to a focus on multistakeholder collaboration. Although there is a significant body of literature on collaborative management and governance of natural resources, the particular challenges posed by multifunctional landscapes, in which there are often contested interests, require closer attention. We present a case study from South Africa to investigate how collaborative stewardship can be fostered in contested multifunctional landscapes. We conducted this research through an engaged transdisciplinary research partnership in which we integrated social-ecological practitioner and academic knowledge to gain an in-depth understanding of the challenges of fostering collaboration. We identified five overarching factors that influence collaboration: contextual, institutional, social-relational, individual, and political-historical. Collaborative stewardship approaches focused on the development of formal governance institutions appear to be most successful if enabling individual and social-relational conditions are in place. Our case study, characterized by high social diversity, inequity, and contestation, suggests that consensus-driven approaches to collaboration are unlikely to result in equitable and sustainable landscape stewardship in such contexts. We therefore suggest an approach that focuses on enhancing individual and social-relational enablers. Moreover, we propose a bottom-up patchwork approach to collaborative stewardship premised on the notion of pluralism. This would focus on building new interpersonal relationships and collaborative capacity through small collective actions. Taking a relational, pluralistic approach to fostering collaborative stewardship is particularly important in contested, socially heterogeneous landscapes. Drawing on our study and the literature, we propose guiding principles for implementing relational, pluralistic approaches to collaborative stewardship and suggest future research directions for supporting such approaches.

- Description: Studies have shown that the practice of formative assessment is a challenge for many teachers in South Africa. Teachers are either entrenched in their old habits and methods of assessment, or they have not been adequately trained and supported to apply formative assessment in the instructional process. The aim of this research was to explore Physical Sciences teachers’ perceptions of formative assessment and the usefulness of Concept Cartoons as a formative assessment instrument to assist teachers in their practice of formative assessment. The perceptions of eight Grade 11 Physical Sciences teachers on formative assessment were sought before and after an intervention. During the intervention, the teachers were trained to use Concept Cartoons as a formative assessment instrument. The teachers’ perceptions were also sought after an implementation phase where they implemented Concept Cartoons as a formative assessment instrument in their own classrooms. The teachers were purposefully selected from six schools in the Port Elizabeth area. A qualitative case study approach, informed by a constructivist perspective, was applied in this study. Data were collected through open-ended questionnaires, semi-structured interviews, and the participants’ post-implementation written reflections. These data were analysed and presented in both narrative and tabular formats, supported by verbatim quotes from the participants. The conclusion that can be drawn from this study is that the use of Concept Cartoons as a formative assessment instrument had a substantially positive influence on the Physical Sciences teachers’ understanding and practice of formative assessment. The data also suggest that Concept Cartoons supported both learner- and teacher learning, thus functioning as an Educative Curriculum Material (ECM). Another finding in this study was that a relatively short intervention (i.e. a workshop) could make a difference in teachers’ learning and professional development. Support, however, is needed, particularly in the form of teaching resources or materials, so as to ensure the translation of knowledge into practice. Though the findings are presented within the context of the six sampled schools, and focussed on Grade 11, further research may determine these findings to be informative for other institutions within similar settings.

- Description: Electronic information is critical to Municipalities, the City of Johannesburg (Road sector) rely on computerised systems to perform their operations and deliver services to its inhabitants. Disaster recovery planning for the City of Johannesburg is crucial and urgent, as it will ensure that the organisation is able to recover the core business functionality of its software, data, and systems after the occurrence of a natural or man-made disaster. Municipalities should have adequate recovery strategies in place in case of disasters. Planning for recovery from a disaster is quickly becoming recognized as a necessity, however organisational leaders are not putting recovery strategies as a priority and thus result in challenges when implementing the recovery processes i.e. Lack of resources, overlooking risk management, lack of leadership commitment to continuity processes and lack of understanding the concept of DRP and BCP. Disruption can happen when not anticipated, It is impossible to foresee what may hit an organisation. It is thus necessary and compulsory for organisation to plan for disasters most especially with ever-increasing dependence of business processes on technology services. The purpose of this research was to assess the adequacy of the Disaster recovery plan at the City of Johannesburg (Road sector) and to develop a strategy to effectively manage the DRP. The research revealed that the DRP at the City of Johannesburg (Road sector) is not comprehensive and that there are other processes that are not effectively implemented. There is a lack of resources for implementing the DRP. The dedicated staff is not adequately technically skilled to implement the disaster recovery processes. This study has revealed that the challenges noted were common to other institutions. An adequate DRP is crucial; capacity management and seamless procurement processes are also crucial for the success of the disaster recovery processes. Theoretically, this research adds to the literature on disaster recovery management and highlights the challenges and complexities involved. Practically, the research provides several lessons and guiding principles that the organisation may consider around disaster recovery management.

- Description: The United Congregational Church of Southern Africa (UCCSA) was established in 1967 through the combination of Church bodies in the Congregational Union of Southern Africa (CUSA), The London Missionary Society (LMS) and Bantu Congregational Church of Southern Africa (BCCSA). The vision of the founders of the UCCSA (LMS) in 1799 was to establish the two Congregational Churches, complete the groundwork through erecting church buildings, provide training to Church Ministers and fund the churches until they became self-sustainable. Thereupon fruitful ways needed to be established to raise funds for the mission of the church. One of the primary methods of raising money was from financial giving of members. The Congregational Church that is the focus of this study forms part of the UCCSA, which includes the church bodies within Southern Africa. The financial statements of this church were scrutinised and it was found to be making losses in the prior 3 financial years (2015-2017). However, in the 2018 financial year the members’ contributions increased by 35 percent compared to the previous financial year. The study therefore explored the factors influencing financial giving behaviours among members at a Congregational Church in Port Elizabeth, taking into consideration a significant positive shift in financial giving in the 2018 financial year in comparison with the prior 3 financial years (2015-2017). Based on this exploration, recommendations will be developed that could assist in enhancing the financial position of the Congregational Church as well as its sustainability as a religious organisation in future. A qualitative, explorative and contextual design was used for the study. The causal model for financial giving described by Finke, Bahr and Scheitle (2006) was used as basis for a theoretical framework. Using purposive sampling, 12 church members that were aged between 18 and 60 years and had recently financially contributed through pledging (tithing), and other monetary donations as part of their church membership were chosen to participate in two focus group discussions, thereby ensuring the data collected was rich with context. The data was analysed by using ATLAS.ti software which has been proven to guarantee the reliability of results. To ensure a high standard of qualitative research, the study adhered to the main principles of trustworthiness by Lincoln and Guba, including dependability, transferability, confirmability and credibility of the research process. Ethical principles of beneficence and non-maleficence, informed consent, privacy, anonymity and confidentiality of data, as well as obtaining ethical clearance, were adhered to in the study. The study yielded data that gave rise to eleven main themes and five sub-themes with regard to the factors that influenced financial giving behaviours of church members. These included: blessings members received from God, church attendance, belonging to a church community and church size, church financial needs (sub-themes included leadership, transparency about the financial position of the church and historic influences), stewardship (sub-themes included non-financial giving behaviours and other financial giving responsibilities), church involvement, tithing, member’s budget, spirituality, and stages of life. Participants were in agreement that blessings from God, belonging to a church community, transparency about the financial position of the church, member’s budget, and spirituality positively influenced their financial giving behaviours in the church. Factors that negatively influenced their giving behaviours included church size, historic influences, non-financial giving behaviours and other financial giving responsibilities. Church involvement, the member’s budget, as well as stages of life both positively and negatively influenced their financial giving behaviours. Participants were not in agreement whether church attendance, leadership and tithing influenced their financial giving behaviours in the church. Finke et al. (2006)’s conceptual model could be used to explain the findings. However, additional factors were identified to be influencing financial giving behaviours among members at the church under study. Some of the main recommendations made, based on the objectives of the study, are: For the Church Council to remain transparent with communication to church members of the financial position of the church; To continue with the stewardship campaign on a yearly basis to encourage members to give financially and of their time and talents to the church; Communicate with members of the church regarding the financial position of the church if it again experiences financial difficulties.

- Description: Hypolithic habitats are important for the persistence of fauna that utilize these habitats as refuges and resource patches. Little is known, however, about the composition and structure of this community in the semi-arid Karoo. The current study therefore aims to explore the patterns and processes behind hypolithic communities, through determining the effect of rock size and baboon presence on the hypolithic community, the influence of rock size on the microclimate experienced under rocks, as well as determining the short- (over five days) and long- (over 12 months) term colonisation of the hypolithic habitat following a rock rolling disturbance, in a semi-arid Karoo environment. The hypolithic fauna encountered, and the temperature and moisture content experienced under a range of rock sizes were measured. Additionally, hypolithic fauna under rocks that were rolled to mimic rock rolling by baboons were sampled after a set period (i.e. over five days and 12 months). Large rocks were found to provide a more stable microclimate than small rocks. The probability of hypolithic fauna presence was influenced by rock size and season, and hypolithic fauna abundance (except in the dry season), richness, body size and biomass did not correlate with rock size. Additionally, the probability of detecting hypolithic fauna under intermediate sized and larger rocks was greater in the presence of baboons than in the absence of baboons, and in the presence of baboons hypolithic fauna richness increased with rock size. Furthermore, it was shown that hypolithic fauna abundance and biomass did not differ under rolled rocks over a short- (i.e. over five days) or long- (i.e. over 12 months) term period. The short-term colonisation of hypolithic habitats was not influenced by season or rock density. Lastly, most of the change in hypolithic community composition (over 12 months) occurred in the first three months and thereafter the hypolithic community composition approached pre-disturbance levels in month 12. The hypolithic habitat was shown to be influenced by a variety of conditions and processes affecting hypolithic community composition and structure. This study therefore contributes to our understanding of the hypolithic invertebrate community in the eastern Karoo, and the influence of rock size, baboon presence, microclimate and colonisation on hypolithic community composition and structure.

- Description: Hypolithic habitats are important for the persistence of fauna that utilize these habitats as refuges and resource patches. Little is known, however, about the composition and structure of this community in the semi-arid Karoo. The current study therefore aims to explore the patterns and processes behind hypolithic communities, through determining the effect of rock size and baboon presence on the hypolithic community, the influence of rock size on the microclimate experienced under rocks, as well as determining the short- (over five days) and long- (over 12 months) term colonisation of the hypolithic habitat following a rock rolling disturbance, in a semi-arid Karoo environment. The hypolithic fauna encountered, and the temperature and moisture content experienced under a range of rock sizes were measured. Additionally, hypolithic fauna under rocks that were rolled to mimic rock rolling by baboons were sampled after a set period (i.e. over five days and 12 months). Large rocks were found to provide a more stable microclimate than small rocks. The probability of hypolithic fauna presence was influenced by rock size and season, and hypolithic fauna abundance (except in the dry season), richness, body size and biomass did not correlate with rock size. Additionally, the probability of detecting hypolithic fauna under intermediate sized and larger rocks was greater in the presence of baboons than in the absence of baboons, and in the presence of baboons hypolithic fauna richness increased with rock size. Furthermore, it was shown that hypolithic fauna abundance and biomass did not differ under rolled rocks over a short- (i.e. over five days) or long- (i.e. over 12 months) term period.

- Description: Around the globe, fossil fuels remain the primary source of energy at around 78% of the world’s total energy consumption. However, the associated carbon emissions, environmental impact, the depletion of fossil fuels and price and cost volatility are factors influencing the growing popularity of research into renewable energy. Solar power is acknowledged as the fastest-growing renewable energy, but the uncertainty surrounding the long-term projections of solar irradiance available for energy conversion is a hindrance when discussing the financial risk with potential investors. This study investigates the quality of freely available solar resource data in South Africa as well as proposes techniques for potential solar farm site comparisons. Tolerance intervals derived within a Bayesian framework provide information on the future available solar resource across multiple sites. These techniques capture the inherent variability in the available solar resource which equips investors with statistical methods that lead to the better understanding of the solar resource and thus aids in better decision-making.

- Description: Service quality has become a major area of attention for organisations as there is proven research that highlights a strong link between business performance, customer loyalty, profitability and customer satisfaction. Therefore, understanding factors that influences the organisations service quality becomes vital for managements (Fukey & Issac, 2014). According to (Kotler, 1991), the main objective of any transport organisation is to achieve passenger satisfaction and loyalty, as well as a superior quality service which is envisioned to keep the service provider at a competitive position in the field of passenger transportation. The primary research problem in this study is to understand perceived service quality challenges within Metrorail Western Cape. The study employs a modified SERVPERF models in developing a model suitable for testing the perception of commuter in public rail transport. In order to assess this, the study adopts a Positivistic view with the aim to produce quantifiable data, through the use of large samples and the testing of hypotheses. The study is quantitative in principle. Quantitative study supports the use of surveys as a means of data collection and because the data is quantitative, this allows the use of rigorous statistical analyses in order come to a conclusion or finding. The results of this are of a descriptive nature and can easily be used to infer to a larger population. A total of 400 questionnaires were distributed electronically using the Questionpro links and manually distributed at stations. From the distributed total, a total of 257 responses were received and analysed using software package STATISTICA with the assistance of a qualified statistician. The key findings indicate that according to the perception of commuters, Metrorail service quality is below the expected levels. The major arears of importance for commuters in Western Cape are safety, communications and reliability of the service.

- Description: This study focuses on the feasibility of exploring potential groundwater zones through assessment of catchment geo-hydrodynamic processes, using hydro-statistic principles and geographic information system-based approaches. The research work integrated analysis of hydrologic variables, geologic structures, and geomorpho-tectonic processes that provide information on spatial variability of hydrologic units in a watershed. The study is aimed at improving conceptual knowledge and presenting the technical feasibility of exploring potential groundwater zones through geo-hydrodynamic perspectives in hydrogeologically challenged environments. The study adopted a case design approach at the Buffalo hydrologic basin headwater in Eastern Cape, South Africa. The methods used in this study include: field mapping of geologic units and structures, digital processing of aeromagnetic map, cross-section profiling of borehole logs, auto-extraction of lineament, streamflow variability and recession assessment, geomorpho-tectonic analysis of surficial drainage pattern, vertical electrical sounding for imaging shallow subsurface layers, and geospatial integration of thematic maps of groundwater multi-influencing factors. The results indicate that the hydrogeological settings of Buffalo watershed comprised of good, moderate, fair, poor and very poor groundwater potential zones which cover 187 km2 , 338 km2 , 406 km2 , 185 km2 , and 121 km2 respectively. The results report that the groundwater system of Buffalo watershed is mainly hosted by the well-drained fractured dolerite and the shallow unconfined sandstone aquifer. The aquifer is bounded by two parallel impermeable valley walls in the north and south. Also, the Buffalo drainage system constitutes a variable head boundary as a groundwater discharge zone. The groundwater discharge which mostly occurs at the Tshoxa upper course, Mgqakwebe, Quencwe, Yellowwoods upper course and the Buffalo River center influence the status of the Buffalo River as a perennial river system. vi The groundwater recharge occurs through the networks of surficial lineaments and fractures concentrated on the sandstone lithosome, mostly in the northern half of the watershed. The surficial tectonic features trend in a WNW-ESE and E-W direction. The groundwater flow system is controlled by the subsurface lineaments which are oriented in west-northwest – eastsoutheast direction. Most of the groundwater recharge is driven by rain which is extreme at the north. The hydro-climatic pattern of the region influences the dendritic drainage system of Buffalo watershed. The geologic characterization and geomorpho-tectonic analysis indicate that the geologic settings are made up of upward-fining lithologic material and siliciclastic materials that were deposited as fill in paleochannels by braided and meandering fluvial systems. The variability in dissection property and the fluvial system indicates that Buffalo hydrologic and geomorphic systems are heterogeneous and complex. The possible impact of these variabilities aligns with the report of geoelectric sections which revealed the heterogeneity of the aquifer intrinsic properties and variability in groundwater yield. The electric resistivity tomography revealed the existence of a fault system and variation in the thickness of the aquifer. Hydrologic characterization indicates the vulnerability status of the rivers within the watershed. In particular, the Ngqokweni River is vulnerable to diminution while Quencwe River has the potential for a flash flood. Buffalo station is an important surface water capture zone. Delineation of groundwater potential zone should incorporate geologic, hydrologic, geophysical, geomorphotectonic, and environmental perspectives due to the inherent relationship among influencing factors. The study therefore identifies groundwater capture zones which can be further explored for groundwater development and to mitigate the stake of water shortage. The study therefore recommends the approach here to the department of water affairs for adoption to map the zones of groundwater potential at a regional scale. The study also provides resourceful information on vii groundwater recharge zones and therefore recommends that the environment and water stakeholders work together to protect the recharge zones from groundwater contamination due to land use

- Description: Since the Department of Correctional Services has been transformed into an institution of rehabilitation and skills development, there is a need for a sound classification system whereby offenders are classified according to their potential for treatment and training programmes that match their risk/needs. The study was conducted in Middledrift Correctional Centre in the Eastern Cape with the aim of examining the effectiveness of correctionally based vocational training programmes towards reducing recidivism. Research towards correctional programmes was necessitated by the extant of recidivism in South Africa. The question is where does the problem lie because offenders are provided with rehabilitation programmes to make them law abiding citizens and reintegrate well into the community up on release but, in many cases it does not become possible as many ex-offenders return to custody either for new offence or parole violation. The study used qualitative design in data collection and in explaining the results. A sample of sixteen recidivists and five correctional officials formed participants for the study selecting using purposive sampling procedures. Involvement in vocational programmes was used as a criteria for selectiong of correctional officials as participants. In-depth interviews were conducted with eight recidivists and all five correctional officials and a focus group interview was held with the other eight set of recidivists. The study examined the impact of vocational programmes on recidivism followed by the factors that hinder effective offender rehabilitation and factors that influence recidivism up on release. The findings of this study were analysed using thematic analysis with the assistance of a voice recorder as a back up for collected data. Findings revealed that a small number of recidivists attend vocational training programmes and these programmes vi (vocational) are short in the centre together with programme facilitators at the time of reporting. Offenders stated that the available vocational programmes are of no interest to them. Participantas stated that vocational training does assist in desisting criminal activities up on release as it provide skills and opportunities for employment to curb unemployment as indicated as a major factor influencing recidivism. Findings also revealed that periodic re-assesment is not adequately conducted and classification for vocational training is not likely to be sufficiently done according to offender risk/needs. The study recommends that, a large number of offenders be provided with vocational training programmes and that offender classification incorporate the principles of RNR model

- Description: Numerous international and South African scholars are critical of the dominant research on the phenomenon of schizophrenia. Rather than refuting dominant biomedical psychiatric conceptualisations of schizophrenia, there is a call for incorporating a focus on the psychology of the person diagnosed with schizophrenia. In South Africa, the integration of the psychosocial components of psychotic experiences into the understanding and treatment of psychosis are still neglected in biomedically-focused psychiatric settings. In relation to this call, the role of clinical psychologists working within these settings seems pertinent. Against this background, this study aimed to explore and describe the perceptions of clinical psychologists, working in a psychiatric setting in South Africa, in relation to the phenomenon of schizophrenia. Informed by a social constructionist theoretical framework, this study utilised a qualitative research design and a semi-structured interview schedule. In-depth, individual interviews were conducted with three clinical psychologists and the transcribed interviews were analysed using thematic analysis. From the data, perceptions were identified as largely polarised in relation to the phenomenon of schizophrenia. These polarised perceptions included: Physical impact of schizophrenia versus social impact of schizophrenia; rehabilitation of schizophrenia versus recovery within schizophrenia; diagnostic frameworks as useful versus diagnostic frameworks as limiting; and institutionally-defined identity versus self-defined identity. In terms of these polarised perceptions, an overarching theme of the medicalisation versus the demedicalisation of schizophrenia was identified. Therefore, the perceptions of clinical psychologists in this study were largely polarised towards either a medicalisation of the phenomenon of schizophrenia or a demedicalisation of it. However, perceptions were also identified that evidenced an integration of the two sides of the polarities, and a holding of tension between seemingly incompatible or incongruent frameworks. The participants perceived psychologists as positioned in the middle ground between the medicalisation and demedicalisation of schizophrenia in a biomedical psychiatric setting. In response to the call for a focus on the psychology of the person diagnosed with schizophrenia, the findings support both the value and the need for an “integration of polarised perceptions”, “holding of the tension”, and “middle ground positioning” of clinicians between medicalised and demedicalised aspects of the phenomenon of schizophrenia.

- Description: arrival of the Fourth Industrial Revolution has brought with it a vast array of new technologies that can be applied across many industries and various applications, to help solve many of the social, economic and environmental issues the world faces. However, it also heralds in an unprecedented rate of change. The agricultural industry is expected to be heavily affected by new technology. As they are run by smaller management teams they may need support from organisations to introduce technologies. The study aims to identify drivers and barriers to technology adoption in agriculture through a conceptual model based on the Technology Adoption Model, Diffusion of Innovation Theory, and a Technology-Organisation-Environment Model, along with a thorough industry analysis. The study obtained quantitative data from 59 respondents from the Eastern Cape farming community. The key findings include the identification of Perceived Usefulness and Industry Pressures as the variables with a significant driving influence on the intention to adopt new technologies. However, Perceived Ease of Use, Employee Knowledge and External Support Structures were found to have a negative relationship with the adoption of technology. It has been interpreted that improvements in these areas may enable farmers to adopt technology more easily but that farmers feel sufficient pressure to make them adopt technology despite the complexities and lack of required internal skills or external support. Due to the low number of respondents, it is not possible to infer the findings on the larger population of farmers. The findings can therefore only be used as exploratory findings which need to be verified in focus groups, with farmers, before any action is taken. However, the findings in the study can be used to aid the definition of frameworks for further studies and the development of action plans to support farmers in the adoption of technology.

- Description: There has been a positive shift in South African laws advocating for children and father’s rights to parent-child relationships. Children often get caught in the middle of their parents’ enduring battles and acrimonious separations or divorces frequently resulting in loss of contact with one parent. The term parental alienation is used to describe this phenomenon. Parental alienation can take many forms with the common thread being the negative impact that it has on the parent-child relationship and an increase in father absenteeism. The psychological effects of absent fathers on children and single parenthood are significant and contribute to social ailments such as substance abuse, violence and abuse. Extensive research has been conducted on the effects of parental alienation on children; however, there is limited research on how fathers experience parental alienation and how it shapes their perception of fatherhood. This study aimed to explore and describe the perceptions and experiences of fathers who have experienced parental alienation. A purposive sampling method was utilized using 6 participants who were sourced from a male-focused NGO in Zwide Township in the Port Elizabeth Metropolitan area. Data was collected through in-depth semi-structured audio taped interviews. Transcribed data was analysed by means of thematic analysis following Guba’s Model of Trustworthiness as a guide for data verification. All necessary ethical considerations were adhered to. Four themes emerged from the study. Participants understood and experienced parental alienation as unjust and painful; parental alienation was perceived as complex and challenging; upbringing influenced their paternal involvement and finally parental alienation affected their perception of fatherhood and their construction of paternal identity.
