Infuence of green marketing mix on sustainable consumption and customer loyalty in Polokwane, South Africa
No full textMarketers throughout all industries are investing enormously towards developing and promoting green products and the retail sector is not exempted from this growing trend. The study aimed to investigate the influence of green marketing mix elements (green product, green price, green promotion and green distribution or place) on sustainable consumption and customer loyalty. To achieve the objective, the research study employed a positivist research paradigm anchored by a quantitative approach using descriptive research design. A structured self-administered survey questionnaire was randomly distributed to retail customers of a sample size of 265 respondents. The data was analysed using SPSS for descriptive statistics and Smart PLS for Structural equation modelling. The key findings reveal that all five hypothesised relationships are positive, however, only four are significant. The strongest relationship was found between sustainable consumption and customer loyalty (β=0.432) while the weakest (yet positive) relationship was between green place and sustainable consumption (β=0.078). The study equips the retailers about the key predictors of consumers’ green sustainable consumption behaviour enabling them to tailor their product offerings and formulate marketing strategies to encourage green buying behaviour. The current study can further assists policymakers to ground their discussions when developing regulations that govern how retail industries should promote, price and distribute their green products.Thesis (Masters) -- Faculty of Economics and financial Sciences, 202
Justification of chest mobile radiographic examinations: : experiences of radiographers in a private radiology practice in the Nelson Mandela Bay Health District
Get PDFThe principle of justification in radiographic imaging aims to best answer a medical question while evaluating the expected benefits of radiation exposure against the probable detriment to the individual patient. The implementation of justification in radiography requires the assessment and evaluation of chest mobile radiographic requests against justification criteria, considering the underpinning principles of radiation: justification, optimisation and authorisation. Diagnostic chest mobile radiographic imaging has been part of healthcare for the last century. Medico-legal requirements by the professional registration body, the Health Professions Council of South Africa (HPCSA), identify justification as an advocated and obligatory practice among radiographers. Yet, justification remains an inconsistent practice among South African radiographers due to several challenges in the healthcare setting. The aim of this study was to investigate the experiences of radiographers regarding the justification of chest mobile radiographic examination requests in a private radiology practice in the Nelson Mandela Bay Health District (NMBHD). A qualitative, exploratory-descriptive and contextual research design was used to gain in-depth data of the experiences of South African radiographers regarding the justification of chest mobile radiographic requests. Data were gathered from the participants using unstructured, open-ended, in-depth individual interviews. Data were transcribed verbatim and coded using Tesch’s eight steps of data coding and analysis process. Two principal themes were constructed during data analysis. Theme one identified the barriers and associated affective responses related to the appropriate implementation of justification of mobile chest radiographic examinations. Theme two recognised recommendations to enhance the implementation of justification by radiographers for mobile chest radiographic examinations. The research study was governed by methods to ensure trustworthiness and ethical practices. Based on the findings of this study, four recommendations were developed to assist radiographers to establish whether a request for mobile radiographic chest examinations is appropriately justified, which can contribute to establishing a radiation safety culture in the research setting pertaining to chest mobile radiography.Thesis (MSc) -- Faculty of Health Science, School of Clinical Care Sciences, 202
Synthesis and characterization of high energy milled silicon nanoparticles for electronic applications
Get PDFThis study demonstrates that high energy milling using a planetary disc mill offers a new simple route to the production of polycrystalline silicon nanoparticles which are suitable for electronic applications. By manipulating process variables such as milling duration and mass of the feedstock load, the microstructure of the nanoparticles can be tuned to meet requirements. The internal structure of the nanoparticles prepared by high energy milling was found to predominantly consist of nanocrystalline silicon and their surfaces are characterised by a disordered layer of silicon sub-oxides and an insignificant proportion of fully oxidized silicon. X-ray diffraction (XRD) patterns and Raman spectra were used to calculate the average crystallite size and correlating it to the milling process variables. The surface chemistry of the nanoparticles was elucidated using X-ray photo spectroscopy (XPS) and was also related to the milling parameters. The internal structure, agglomeration and aggregation of the particles were tested using high resolution transmission microscopy (HRTEM) and complemented by scanning electron microscopy (SEM). Conductivity tests were done on the particles to ascertain their suitability for electronic applications. It is demonstrated that the longer the milling time, the smaller the sizes of particles and crystals. The sizes also depended on the mass of feedstock load. 30 g feedstock loads resulted in average nanoparticle size which were 30 - 40 % larger than for 10 g loads. The average size of nanoparticles produced were in the range 50 – 80 nm as measured by SEM. The distribution of the size of particles became less polydisperse with increase in milling time and a reduction in feedstock load. The particles were devoid of significant SiO2 layer and hence were confirmed by conductivity tests to be electrically active. Data from XPS indicate that the silicon nanoparticles have a unique surface chemistry which is consistent with the silicon surfaces being dominantly oxygen terminated.Thesis (Masters) -- Faculty of Commerce and Administration, 202
A single centre study evaluating adherence to methotrexate monitoringguidelinesin patients with rheumatoid arthritis
Get PDFIntroduction: Methotrexate (MTX) is considered a first-line agent for the treatment of rheumatoid arthritis (RA) and regular blood test monitoring is advised in treatment guidelines to identify potential toxicity. Failure to adhere to monitoring guidelines for methotrexate use may compromise patient care. Identifying and correcting variability in care may optimise the safe use of this medication and improve patient outcomes. Aims: This study aimed to evaluate adherence to guidelines on methotrexate safety monitoring in rheumatoid arthritis patients at an Eastern Cape hospital and to establish whether a dedicated rheumatology outpatient department (OPD) performs this task more effectively than a general medical outpatient department (MOPD). Method: This retrospective cross-sectional single-centre study was conducted at Frere Hospital in the Eastern Cape over one year from 1 January 2019 to 31 December 2019. Adult patients over the age of 18 years who received methotrexate for rheumatoid arthritis during the study period and attended either the rheumatology OPD or the MOPD at Frere Hospital were included in the study population. Permission to undertake this study was obtained through the Faculty of Health Sciences Research Ethics and Bio-safety Committee at Walter Sisulu University and the Cecilia Makiwane and Frere Hospitals Research and Ethics Committee. The random sample generator tool on Microsoft Excel was used to select patients from the Frere Hospital Pharmacy Database who was prescribed methotrexate for rheumatoid arthritis. Laboratory test results were accessed through the Labtrak system of the National Health Laboratory Service (NHLS). The number and type of blood test done as recommended in a South African Methotrexate use guideline by Hodkinson et al, was documented on a data collecting sheet. Two or more blood tests done within a three-to six month period was considered adherent to the guideline. The hospital management system version two (HMS2) was used to see which clinic the patient attended. iii Results: There was 53% adherence (95% Confidence Interval 42-65%) overall to guideline. In the study sample, 64% of patients were from Rheumatology OPD and the remainder were from MOPD. There was 78% (95% CI 62-89%) adherence in the Rheumatology OPD compared to 22% (95% CI 11-38%) in MOPD. No significant association was found between the number of FBC tests and the site of testing (p-value = 0.346) or for Creatinine tests (p-value = 0.078). However, a significant association was found with ALT tests and the site of testing (MOPD or rheumatology OPD) with p-value = 0.010, although this is likely a chance finding. Conclusion: Adherence to a South African guideline for methotrexate safety monitoring was found to be suboptimal at the study centre. Adherence was better in the dedicated Rheumatology OPD compared to a general medical OPD. Education regarding the correct use of guidelines in different health settings by medical professionals is advised.Thesis (Masters) -- Faculty of Medicine and Health Sciences, 202
Housing market dynamics and economic growth in South Africa (1994 – 2019)
No full textThe housing market contributes significantly to economic growth. On this background, the study examined South Africa’s housing market dynamics, particularly determinants of demand, supply, and formal housing prices. Furthermore, the study looked at the impact of housing prices on economic growth from 1994:Q1 to 2019:Q2. The study period is important as it covers the new political dispensation in South Africa where the country entered a new democracy in 1994. The first three objectives of the study were to identify the determinants of housing demand, supply, and prices. The theory of demand and supply provided the theoretical framework for these models. Estimation of the housing demand, supply and price models was done by the employing Seemingly Unrelated Regression (SUR) technique. The Three Stage Least Squares (3SLS) model was estimated for robustness. Findings from SUR and 3SLS confirmed that Housing Demand (HD) is negatively and significantly influenced by residential Building Costs per Square Meter (BCSM), Housing Supply (HS) and Financial Costs (FC); and positively influenced by House Prices (HP). In addition, HS is negatively affected by BCSM, HD, Production Costs (PC) and Urban Population (UP); and positively influenced by HP and Residential Construction Confidence (RC). Lastly, HP are negatively affected by Prime Overdraft Rate (POR) and RC; and positively influenced by BCSM, HS, HD, Coincident Business Cycle Indicator (CBC) and residential Valuation (VAL). The fourth objective was to examine the impact of house prices on economic growth. An economic model was specified with Gross Domestic Product (GDP) as its dependent variable. The new growth theory provided the theoretical framework for this model. The Johansen co-integration technique confirmed a long run-term relationship between economic growth and house prices. The Vector Error Correction Model (VECM) was estimated to analyze the long and short run relationship among the variables. Empirical results confirmed that house prices have a positive impact on economic growth. Results further confirmed that CBC and Unemployment Rate (UR) are also positively related to GDP. POR and Leading Business Cycle indicator (LEBC) are negatively related to GDP. Granger Causality test was performed to analyze the causality between house prices and economic growth. The results indicated that there is a long run unidirectional causality from house prices to economic growth. With these results, the study recommends policy formation emanating from continuous research by establishing a human settlement agency or task team. The team can establish procedures for data collection and maintain a database for all kinds of housing market data. Their mandate includes research on commissioning of new towns and/or cities to boost housing supply. The government should avail more land and relax restrictive regulations and minimize red tape to ensure that houses are supplied to meet the growing demand as well as to stabilize prices. Policies to promote confidence and stabilize building costs are needed. These variables indicated significant influence on housing dynamics. It is also recommended to incentivize households to participate on the mortgage market. This assist both households through the wealth effect which positively influence increase in economic activity in South Africa.Thesis (DCom) -- Faculty of Management and Commerce, 202
Assessing the impact of access to climate services on smallholder farmers cropping decisions and household food security in Elundini Municipality, Eastern Cape province
No full textClimate variability has significant implications for crop production and overall food security. Climate services which provide tailored and localised climate information have the potential to enhance farmers understanding of climate patterns and support informed decision making. The purpose of the study was to assess the impact of climate services on smallholder farmers cropping decisions and household food security. The study adopted a cross sectional household survey on 217 smallholder crop farming households from Elundini Municipality. Structured questionnaires and face to face interviews were used to collect the required data from the farmers. Descriptive analysis was used to identify the types of climate service accessed by smallholder crop farmers in the study area. The probit model was used to examine factors influencing smallholder crop farmers access to specific climate services. The household dietary diversity score was used to measure household food security among smallholder crop farmers. The propensity score matching model was used to assess the impact of accessing specific climate services on cropping decisions and household food security. The results indicated that most farmers 77 percent in the study area had access to climate services. The results further showed that many farmers had access to short term weather forecast 79 percent with very few accessing seasonal forecast 22 percent. The results also revealed that access to both short term weather and seasonal forecasts is positively influenced by ownership of mobile phones and access to extension services. Similarly access to short term weather forecasts is positively influenced by age monthly income ownership of radio timely climate information and perceiving that climate change has negative effects on crop production. Land size knowledge of climate change and climate services accuracy are positive and significant factors influencing access to seasonal forecasts. Most of the smallholder farming households in the study area had higher dietary diversity scores 66 percent. Moreover access to short term weather and seasonal forecasts has a positive and significant impact on cropping decisions and household dietary diversity scores. The study concludes that climate services improve cropping decisions and household food security among smallholder crop farmers in Elundini Municipality. The study recommends that there should be investments in awareness programmes that will educate farmers about the importance of climate services and how to acquire and interpret both weather and seasonal forecasts. Stakeholders interested in improving smallholder farmers access to climate services should consider whether farmers own smart phones and have access to extension services arable land knowledge of climate change and if the climate services are accurate for smallholder farmers. In addition to improve crop production and household food security in the face of climate change access to climate services by smallholder farmers should be considered.Thesis (MSc) -- Faculty of Science and Agriculture, 202
The Effects of Using English as A Language of Learning and Teaching on Learner Academic Performance in Senior Phase of Mthatha, Eastern Cape Province
No full textIn-service teachers’ lack of adequate instructional approaches to effectively teach geometric concepts and poor learner performance in geometry were the major rationale for this study. The preparedness of in-service mathematics teachers cannot be overlooked. The aim of this study was to develop in-service mathematics teachers’ skills for integrating GeoGebra in the teaching of geometry in a multiple case study of secondary schools in Oliver Reginald Tambo Inland district. The researcher employed ICTs in education, GeoGebra as a learning object, and in-service teachers as conceptual framework that undergirded the study. For the theoretical framework, this study utilised the Technological Pedagogical and Content Knowledge (TPACK), Constructivist Learning Theory, and the Teaching Change Frame (TCF). This study focused on the technological components of the TPACK framework, such as Technological Knowledge (TK), Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK) and TPACK. The researcher found that constructivism is consistent with the TPACK framework. The implementation of the TPACK was guided and assessed using the Teaching Change Frame. Regarding the methodology, the study followed the pragmatic paradigm and utilised mixed method research following the concurrent triangulation design. Due to the nature of the study, the quantitative method in this study had dominance over the qualitative method. The study was conducted in schools situated in OR Tambo Inland district in Eastern Cape Province of South Africa. Purposive sampling method was adopted to sample twelve schools, in the ratio of seven urban to five rural schools. The sample consisted of 29 secondary mathematics in-service teachers, 20 from urban schools and nine from rural schools. The TPACK questionnaire, training lesson evaluation form, observation schedule checklist and interview were used to collect data. Reliability and validity were ensured through Cronbach’s Alpha reliability test and a pilot study, whereas data trustworthiness was ensured through qualitative measures including member checking. Findings revealed that the intervention to integrate GeoGebra in geometry teaching impacted positively on in-service teachers with a highly statistically significant and a gain of medium to large effect size on pre- and post-intervention. Thus, the positive impact of using GeoGebra in geometry teaching resulted in significant differences before and after the training of in-service teachers. The findings obtained from the training showed that in-service mathematics teachers developed skills of integrating GeoGebra software in their teaching of geometry. After the training, participants felt that integrating GeoGebra in geometry teaching afforded mathematics teachers the opportunity to use learner-centred approaches, teach geometry with confidence, maintain learners’ attention and alertness in class, and improve learners’ performance. Further, findings obtained from observing participants demonstrating their experience in integrating GeoGebra showed that, not only did in-service teachers’ confidence of using GeoGebra improve significantly, but also their ability to use GeoGebra to set geometry questions. The researcher also observed that integrating GeoGebra when teaching geometry had positive effects on teachers’ understanding of geometric concepts. The findings showed significant difference in participants’ confidence in delivering lessons that can combine technology (T), geometry content (C), and pedagogical (P) knowledge. As a contribution, recent literature has been added to the existing body of knowledge in teacher education related to technology integration studies. Among them is the invention of a new teacher training model called Technology Integration Model for Teaching and Learning. Establishing a GeoGebra institute in teacher training institutions, and engaging Department of Basic Education (DBE) or provincial or district curriculum specialists to train mathematics teachers to integrate GeoGebra were recommended for policy and practice. For further research, the study recommends following-up on trained in-service teachers to track their adoption of GeoGebra in geometry teaching, learner’s performance in geometry, and their perceptions of being taught geometry using GeoGebra.Thesis (D.Ed) -- Faculty of Education Sciences, 202

Yet there are limited studies on how trauma survivors perceive and experience trauma-focused treatments such as prolonged exposure therapy (PE) for PTSD, especially in low- and middle-income countries (LMIC). AIM The study aimed to explore the perceptions and experiences of trauma survivors receiving prolonged exposure therapy for PTSD and the general acceptability of PE for PTSD in a LMIC
The effectiveness of the Therapeutic Sandstory Method as a focused intervention with a child: a descriptive single case study
Get PDFThis study explores and describes a phenomenological case study, illustrating a postmodern constructionist orientation to sandtray work with a South African child. The Therapeutic Sandstory Method (TSM) involves the innovative integration of a variety of tenets when working with children– constructing sandworlds, storytelling, the reflection of stories and coherent therapeutic documents in therapy collectively facilitating the healing process. This novel method enables children to translate and communicate their own personal experiences and traumas into a concrete form through storytelling and metaphoric connections constructed in their sandworld. It is anticipated that the TSM is a brief yet feasible, child-centered therapeutic engagement designed to continue the therapeutic process outside of the therapy setting, making it ideally suited for children and adolescents from under-resourced communities. The results of the study revealed improved interpersonal functioning and emotional wellbeing after eight sessions. Contextualized narrative and social constructionist findings are discussed and recommendations made pertaining to future research and practice using TSM with children in therapy.Thesis (MA) -- Faculty of Humanities, Psychology, 202
Transnational Activities of Women-Focused Civil Society Actors in Southern Africa
No full textSince the 1990s, the opening up of democratic spaces has been characterised by growing transnational activities and regionalisation of non-state actors. In Southern Africa, intergovernmental organisations (IGOs) such as the Southern African Development Community (SADC) began to recognise civil society actors and to integrate and prioritise gender and women issues within their policymaking structures. 1 This was assisted by the formulation of norms at a global level which could be diffused to regional and national policies, leading to greater non-state activity in the SADC area. It was achieved through, firstly, the establishment of an eminent group of commissioners in the early 1990s to review the situation of women across the region. Secondly, following the 1995 Beijing International Women’s Conference, a task force was created to draft a Regional Plan of Action to begin to address gendered insecurities across Southern Africa. Finally, the first meeting of the SADC Ministers Responsible for Women and Gender Affairs was convened in 1997 (Made and Morna, 2009: 34)
