- Description: This work critically interrogates the portrayal of masculinity in plays written by both male and female Nigerian playwrights. Selected plays (three from each author) of Wole Soyinka, Femi Osofisan, Tess Onwueme and Tracie Utoh-Ezeajugh were studied in order to proffer answers to certain critical questions, some of which include determining whether the way male playwrights construct the psychosocial temperament of lead male characters differs from how such is depicted in the works of female authors. The study also sought to ascertain how the concept of masculinity has evolved through the careers of three generations of playwriting in Nigeria. While evaluating the differences that exist in the portrayal of masculinity in the male lead characters in the works of selected male playwrights when compared to those of their female counterparts, the study equally examines the portrayals of male identities in the selected texts. It also evaluates the notion of masculinity shift among the three generations of Nigerian playwrights with a view to ascertaining how textual portrayals of characters and events reflect the changing values that are held about male identities in different Nigerian societies. In executing these objectives, the study adopts a qualitative method, and then eclectically employs Raewyn Connell’s (1995) Theory of Masculinity, Judith Butler’s (1990) Theory of Performativity, and Louis Athan Althusser’s (1970) Idea of Interpellation as the Theoretical Framework to guide the analysis and interpretation of the selected texts. Furthermore, the study follows a constructivist model that involves several stages including the identification of the selected plays as the main texts, a perusal of the plays, review of the literature on gender portrayals in the plays, and a critiquing of the portrayal of masculinity in them. The findings of the analysis reveal that masculinity is a conditional, provisional and elusive subject. It is created in a certain socio-cultural and historical context and evolves according to situations. The studied texts demonstrate the artistic agency of women in constructing men’s masculinity. They imply that masculinity and femininity are like Siamese twins in the building of a peaceful, strong, and new nation. Moreover, the playwrights under study divulge that power is the key factor in (de)constructing and (re)defining of masculinity of men. Through their plays, the dramatists challenge and attempt to change the stereotypical constructs of men, dismantle the traditional gender roles and propose a new way of envisioning gender, where hegemonic principles can be nullified. It is therefore the submission of this work that Soyinka, Osofisan, Onwueme and Utoh-Ezeajugh do not affirm the social construct of masculinity but rather interrogate them. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Green leafy vegetables are important in human nutrition, but their cultivation is limited to a few staple ones. These vegetables possess high nutritious and therapeutic properties that could help in achieving nutritional security and alleviating the burden of some diseases. A typical example is Celosia argentea, which in South Africa, is little known and grossly under-utilized despite its numerous nutritional and pharmacological values. The present study investigated the cultivation, nutritional and pharmacological potentials of C. argentea at three stages of maturity of two trials. Evaluation of cultivation in the greenhouse towards possible domestication of C. argentea included seed viability test, seed germination under varying temperatures (5, 10, 15, 20 25 30, 35, 40°C), light conditions (continuous light, continuous darkness, alternating light and dark (12h light/12 dark photoperiod) and sowing depths (0, 1, 2, 3, 4 and 5cm). The nutritional evaluation assessed the proximal, mineral, vitamins and antinutrient content of the plant; while pharmacological potentials of C. argentea were evaluated by investigating the ultramorphology, phytochemical content, anti-oxidant, antimicrobial, toxicity and cell-based anti-inflammatory properties of the plant at different stages of growth. Germination experiment revealed that optimum seed germination requirements for C. argentea were 25°C, alternating light and dark regime and a sowing depth of 1cm. Microrphological assessment of C. argentea revealed that the leaves were amphistomatic; with the abaxial surface having higher stomata density. Characteristic, distinguishing protuberances were observed at the polar ends of the stomata on the adaxial surface of the plant epidermis, and the major elements on the foliar epidermis were beryllium, carbon, oxygen and potassium; while pigmentation and colouration, showing localization of bioactive compounds were mostly at the site where trichomes were abundant. Growth parameters and yield potential (plant height, stem girth, leaf area, number of leaves, number of branches, number of days to flowering, number of flowers as well as dry and fresh weight) of C. argentea showed that for agricultural practices on the field, increase in growth parameters should be expected around 4-5 weeks after transplanting while higher yield should be expected around 7-9 weeks after transplanting. The results encouraged cultivation during summer or late spring for best farm management. Proximal, mineral, vitamins and anti-nutrients content of C. argentea at three different maturity stages of two trials were performed using AOAC, ALASA and inductively coupled plasma-optical emission spectrometer techniques. Results revealed that the pre-flowering stage of growth had the highest ash (28.15± 0.10 percent) and crude protein (25.80 ± 0.20 percent) contents. While post-flowering stage had the highest carbohydrate (28.51± 0.20 percent and 36.16± 0.22 percent), crude fibre (33.41± 0.87 percent) and energy (435.28± 27.6 percent) with low fat and moisture (8.43± 0.15 percent and 6.35±0.09 percent) contents respectively; while no marked demarcation in most mineral contents in all the growth stages was observed. Zinc was highest at the flowering stage of growth, while vitamin contents decreased as the plant approached maturation. Antinutrients content of the plant was not dependent on growth stage. Total phenols, flavonoids and proanthocyanidin content of C. argentea were evaluated colourimetrically, while the antioxidant potency of the aqueous, acetone and methanolic extracts was measured using 2,2 diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), Ferric reducing antioxidant power (FRAP) and total antioxidant capacity (TAC) models. All the solvent extracts of the flowering stage had the highest total phenolic (80.75±4.21GAE/g), flavonoids (946.19±7.87QE/mg) and proanthocyanidin contents (100.90±1.29 CE/g); with the acetone extracts showing significantly higher phytochemical content. The flowering stage exhibited the best radical inhibitory activity, with the methanol extract having the highest scavenging power for ABTS and DPPH radicals, while acetone extract showed the highest inhibition against FRAP and highest total antioxidant capacity. The antimicrobial potential of the aqueous acetone and methanolic extracts of C. argentea evaluated using agar dilution method against six bacteria (Klebsiella pneumonia, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus) and four fungal strains (Candida glabarata, Candida albicans and Penicillium aurantiogriseum and Penicillium chrysogenum) showed that Streptococcus pyrogenes and P. aeruginosa were susceptible to the methanol extracts of all the growing phases of both trials at 10 mg/mL; while Klebsiella pneumoniae was susceptible at 10 mg/mL to only the methanol post-flowering extracts of both trials. C. albicans and P. aurantiogriseum were highly susceptible to all the extracts. Possible toxicity evaluated using brine shrimp lethality assay and calculation of LC50 against brine shrimp nauplii revealed that C. argentea was not toxic at any stage of maturity at all concentrations evaluated. Anti-inflammatory activities and cytotoxicity of C. argentea extracts evaluated using RAW 264.7 macrophages and 3T3-L1 cell lines revealed that the acetone extract of the flowering stage had moderate anti-inflammatory activity with no significant toxicity against activated macrophages. Findings from this study indicate that C. argentea is a safe functional leafy vegetable of high nutritional and pharmacological importance which can easily be cultivated and domesticated in South Africa. This could significantly alleviate the burden of micronutrient deficiencies among pre-school children in rural communities. , Thesis (PhD) (Botany) -- University of Fort Hare, 2019

- Description: The main objective of this study was to critically investigate the mediating role that the use of mobile technology plays in the linkage between customer satisfaction and customer loyalty in a semi-urban environment. The research problem focused on the application of mobile technology in the linkage between customer satisfaction and customer loyalty in the clothing industry in King Williams Town. In accomplishing this objective, this research study hypothesised that mobile technology plays a mediating role in the linkage between customer satisfaction and customer loyalty of customers of clothing retailers in South Africa. Multiple regression was conducted to test for the first hypothesis. The first secondary objective aimed at establishing if there is disconfirmation between customer expectations and the performance of clothing retail outlets in King Williams Town. In exploring this objective, it was hypothesised that there is negative disconfirmation between customer expectations and performance. A paired sample test was conducted to test for this hypothesis. In addition, the influence of service quality and customer satisfaction on customer loyalty was explored. To accomplish these, it was hypothesised that both service quality and customer satisfaction have an influence on customer loyalty. Pearson’s Correlation and the Chi-Square Test were applied to test the influence of service quality and Customer satisfaction on Customer loyalty. Data was analysed using the Statistical Package for Social Sciences (SPSS) statistical software. Regression analysis, chi-square tests, Paired sample tests and correlation reports were used to analyse data inferentially. Reliability and validity of the research was also tested using Cronchbach’s alpha test. The results show that mobile phones have become a basic necessity for customers and that mobile technology plays a mediating role in the linkage between customer satisfaction and customer loyalty; however, the mediation is partial. The results also show that there is positive disconfirmation between customer expectations and retailer performance; that both service quality and customer satisfaction have a positive correlation with customer loyalty and that mobile technology enhances customer loyalty. Finally, the results show that the total service experience of customers is favourable because the five components of service quality were rendered at a high level of service quality. The study offers several managerial recommendations. Firstly, retail managers should make strategic investments in mobile technology and use this technology to the full to reap the benefits of technologically advanced mobile communication. Secondly, managers should be creative in their use of this mobile technology to enhance customer satisfaction and, hence, customer loyalty. Thirdly, managers should prioritise the improvement of all five components of service quality in order to enhance customer loyalty. Finally, managers should provide a customer-centred service experience that exceeds customer expectations for service quality and mobile communication, one that maximises customer satisfaction and loyalty. The implementation of these recommendations could result in clothing retailers providing a customer-focused service experience in all five aspects of service quality. To successfully implement these recommendations, clothing retailers should: ensure that expectations created, could be accomplished or exceeded to build and enhance customer satisfaction; create expectations that are realistic to avoid negative disconfirmation and hence customer dissatisfaction; implement innovative and creative mobile communication strategies to build and enhance customer loyalty; and finally, improve loyalty programmes to enlarge the customer base. , Thesis (MA) -- Faculty of Management and Commerce, 2012
