- Description: Regional financial integration (RFI) is perceived as the other avenue through which the financial sector of member countries can develop given the vast benefits which associated with it. These benefits include mobilization and allocation of efficient resources to productive sectors within the region which plays a very important role in the development process. Given this background, the study examines how regional financial integration promotes financial sector development in the SADC region utilizing the panel data model for the period 1996 to 2015. The empirical results revealed that regional financial integration does have an impact on the financial sector development in the member countries in the region. Furthermore, the results showed that regional financial integration require a certain degree of institutional quality for RFI benefits to accrue. The empirical results imply that the countries in the SADC region should pursue regional financial integration. This can be achieved through commitment by all authorities in the region. There should be a firm commitment to broader economic integration and building on existing networks and build the necessary infrastructure.

- Description: Adverse childhood experiences (ACEs) are of great concerns in public health. They are traumatic experiences that occur during childhood. ACEs include various forms of abuse and maltreatment which can be emotional, physical, verbal and sexual, different degrees of household dysfunction such as growing up with substance abuse like drugs and alcohol, witnessing domestic violence, mental illnesses, crime in the home and parental disharmony. Although childhood adversities and traumatic experiences occur before the individual is 18 years of age, the effects of such experiences can last a lifetime causing mental and chronic medical illnesses. Resilience is perceived as an antidote to the detrimental effect of ACEs. It is a situation in which an individual displays a high level of effectiveness after a significant misfortune or adversity. This study was conducted to assess the level of resilience towards adverse childhood experiences among public secondary school children in Alice. Data were collected with the aid of a wellstructured questionnaire from 418 public high school students using Convenience sampling method. Factors influencing resilience among the learners were examined. Consequently, the data collected were analyzed using descriptive statistics and ordered logit regression model. From the results, it is observed that the majority of the learners live with their grandparents and the most prevalent form of ACEs is emotional abuse, followed by sexual abuse while community violence is the least common childhood adversity. This study further reveals that some of the respondents experienced more than one form of adverse childhood experience. In addition, irrespective of what the students have been through, they are largely observed to be resilient. Analysis from the ordered logit regression model shows that age, class in school, gender, religion, race and who the student lives with are significantly related to resilience. The study, therefore, recommends a functional counseling unit in the schools while student-teacher relationship must be encouraged

- Description: In Primary Health Care system there are different categories of nurses that have different roles to play within their facilities, such as registered nurses, enrolled nurses and enrolled nursing assistants, operational managers at functional level within the Primary Health Care Clinics and also overall supervisors. The study focus was on operational managers as they are the key role players in quality client care within Primary health Care clinics, King William’s Town in Buffalo City Health District in Eastern Cape Province. The aim of the study was to describe the role of nurse managers in ensuring client satisfaction within the Primary Health Care Clinics at Buffalo City Health District in order to ensure effectiveness of Health Core Standards. The research questions were: The research questions that was addressed in this study Main question: “What is the role of nurse managers in ensuring client satisfaction within Primary Health Care Clinics at Buffalo City Health District?” Sub questions: How do you ensure client safety in your facility? How do you monitor client waiting time in your facility? What strategies can assist in the improvement of client satisfaction in Primary Health care clinics? The objectives were to explore and describe role of nurse managers in ensuring client satisfaction regarding safety within the Primary health Care clinics in Buffalo City Heath District, explore and describe role of nurse managers in client satisfaction about waiting time within Primary Health Care Clinics and to recommend strategies to improve client satisfaction within the Primary Health Care clinics in order to improve client satisfaction. A descriptive, explorative, qualitative, contextual design was used to describe and explore the role of operational manager in ensuring client satisfaction regarding client safety and waiting time within Primary Health Care Clinics. Purposive sampling method was used to select seven operational managers. Six operational managers participated in the study as one of them was bereaved during the interview period. One on one interviews with operational managers was used to collect the data. Data was collected until it reached saturation. Data collected was analyzed using Tesch’s steps of data analysis for qualitative research. vi The results were that the operational managers are performing their roles, but find it difficult to fully satisfy clients as they experience some roles’ related challenges in ensuring client satisfactory services. Related roles’ challenges were unavailability of enough nursing staff to cover all the programmes due to shortage of staff, poor infrastructure in some of the clinics, lack of support and appreciation from some of their supervisors, absenteeism of staff that negatively affect operational manager’s planning and organisation role, failure to deliver medication in time. They recommended some strategies regarding improvement of client satisfaction within the Primary Health Care clinics. The recommendations were, the department of health to fill in nurses and staff vacant posts, facilitation of prompt delivery of medication to Primary Health Care Clinics, the department to attend to poor infrastructure, District office to consider staff satisfactory survey, commitment of clinic supervisors in their monthly visits and the study findings be used when conducting further studies related to ensuring client satisfaction regarding safety and waiting time

- Description: In order to formulate or implement relevant food security programmes in rural areas, it is important to have a deep understanding of the food security status of rural households. Accordingly, this study was conducted to assess the food security status of rural households in Raymond Mhlaba Local Municipality. The study also sought to identify the socio-economic characteristics that influence household food security status. The research relied on primary data. Primary data were collected by using a structured questionnaire, which covered both demographic features of respondent households, and their recent food consumption patterns. The household survey was conducted among 272 participants of Raymond Mhlaba Local Municipality. Statistical tools employed in this study included both descriptive and inferential statistics. The main descriptive statistics used were frequency tables, means and percentages in relation to a number of demographic characteristics and food security indicators. The main indicator of food security/insecurity used in the study was the Household Dietary Diversity Score (HDDS). After calculating the HDDS for each household, households were defined as either food secure or insecure depending on whether their HDDS was above or below the average HDDS. A logistic regression model (binary or dichotomous) was then used to identify socio-economic factors that influence some households to have above-average rather than below-average food security levels. The Binary logistic regression model revealed that four out of eight variables included in the model were significant in explaining the variation in the food security situation of households in the study areas, namely age of household head, education level of household head, household income and household size. Of these, the first three were positively associated with aboveaverage food security status, while household size had a negative association. A Tobit model was further used to identify the determinants of the household dietary diversity score. The exact same variables were significant from the Tobit analysis, and in the same manner.

- Description: The aim of the study was to establish a deeper understanding on the stratigraphy, sedimentology, petrology, organic geochemistry and diagenesis of the Ecca Group, and to provide new insight on the shale gas occurrence and potential of the Ecca Group, Karoo Supergroup in the southern Karoo Basin. The Ecca Group stratigraphy is divided into five formations from the bottom upwards, namely the Prince Albert, Whitehill, Collingham, Ripon and the Fort Brown Formations. The stratigraphy of the five studied stratigraphy’s formations is now sub-divided into two new different members each. These subdivision was based on field investigation of lithological features, sedimentary structures, facies characteristics and stratigraphic correlation points. Each member has been assigned a lithological name. Sixteen sedimentary facies have been identified in the study area and were subdivided into six distinctive facies associations (FA 1, FA 2, FA 3, FA 4, FA 5 and FA 6). Sedimentological characteristics of facies associations identified indicate that the Ecca Group sediments initially accumulated in a deep marine environment, progressed through turbidite, shallow marine and ended in lacustrine and deltaic environments. The stratigraphic succession of the Ecca Group constitutes a perfect regression sequence, indicating that the marine water gradually retreated and the sea-level gradually dropped. Grain size analysis was performed on twenty four Ecca Group sandstone samples. Statistical parameters of grain-size statistical parameters, linear discriminate functions, passega diagrams and bivariate analysis were used to reveal the hydrodynamic conditions and depositional environments. The results indicated that the Ecca Group sandstones are mostly fine to very fine grained, near-symmetrical, mesokurtic and indicative of dominance of low energy environments. The linear discriminate function analysis for the Prince Albert, Whitehill, Collingham and Ripon Formations samples indicates that the majority of the deposits were by turbidity currents all in a deep marine environment; whilst of the Fort Brown Formation samples are lacustrine/deltaic deposits. The depositional mechanism C-M plot indicates that majority of the Ecca Group sediments clustered in the PQ and QR field suggesting deposition mainly by suspension, rolling or saltation as well as graded suspension. Modal mineral composition analysis indicates that the main framework grains of the Ecca Group sandstones are quartz, feldspar as well as lithic fragments derived from metamorphic, igneous and sedimentary rocks with a few from volcanic origin. The Ecca Group sandstones iii are immature compositionally and can be classified as feldspathic wackes and lithic wackes. The QFL ternary diagram revealed a dissected and recycled orogen arc provenance; whereas QmFLt ternary diagram point to dissected arc and transitional arc sources to an active continental margin as well as recycled provenance. These provenance characteristics suggest a metamorphic and plutonic terrains influence as the main source rock with minor debris derived from recycled sedimentary rocks. The weathering diagram and semi-quantitative weathering index suggests that the sandstones from the Ecca are mostly from a plutonic source area under arid to humid climatic conditions. The detrital modal compositions of these Ecca Group sandstones are related to a strike-slip setting, back arc to continental margin setting. Diagenetic features of the Ecca sandstones and shales are subdivided into early, late (burial) and uplift-related diagenetic stages. Mechanical compaction, recrystallization, cementation, replacement and the dissolution of framework grains or cements are some of the main diagenetic processes that largely affected the Ecca sediments. Early diagenetic processes include cementation, point/planar contact, formation of pyrite, hematite cements and mineral inversions. Recrystallization, replacement, compaction, overgrowth, albitization, seritisation, illitization, concave-convex and suture contacts as well as dissolution took place mostly in the later diagenetic stage due to increase of temperature and pressure as burial depth increased. The uplift-related diagenetic stage was mostly affected by deformation and fracturing, calcitization, dissolution, erosion and weathering. Diagenetic processes largely affected the porosity and permeability of the reservoir rock properties of the Ecca Group. Organic geochemistry results indicate that the sediments were highly weathered and the TOC values ranging from 0.10 to 7.35 wt% with mostly less than 0.5%, which indicate the source rocks have poor oil potential. The majority of the Ecca Shales have HI values less than 50 mg HC/g, TOC indicating Type-IV kerogen mostly derived from reworked organic matter with very little hydrocarbon generation potential. The relatively high Tmax (oC) and vitrinite reflective values indicate that most shales are thermally over-matured thus they have low hydrocarbon pontential.

- Description: The genome is the complete set of an organism's hereditary information that contains all the information necessary for the functioning of that organism. Complete nuclear, mitochondrial and plastid DNA constitute the three main types of genomes which play interconnected roles in an organism. Genome sequencing enables researchers to understand the regulation and expression of the various genes and the proteins they encode. It allows researchers to extract and analyse genes of interests for a variety of studies including molecular, biotechnological, bioinformatics and conservation and evolutionary studies. Genome sequencing of Rhodophyta has received little attention. To date, no published studies are focusing on both whole genome sequencing and sequencing of the organellar genomes of Rhodophyta species found in along the South African coastline. This study focused on genome sequencing, assembly and annotation mitochondrial and plastid genomes of Gelidium pristoides. Gelidium pristoides was collected from Kenton-on-Sea and was morphologically identified at Rhodes University. Its genomic DNA was extracted using the Nucleospin® Plant II kit and quantified using Qubit 2.0, Nanodrop and 1% agarose gel electrophoresis. The Ion Plus Fragment Library kit was used for the preparation of a 600 bp library, which was sequenced in two separate runs through the Ion S5 platform. The produced reads were quality-controlled through the Ion Torrent server version 5.6. and assessed using the FASTQC program. The SPAdes version 3.11.1 assembler was used to assemble the quality-controlled reads, and the resultant genome assembly was quality-assessed using the QUAST 4.1 software. The mitochondrial genome was selected from the produced Gelidium pristoides draft genome using mitochondrial genomes of other Gelidiales as search queries on the local BLAST algorithm of the BioEdit software. Contigs matching the organellar genomes were ordered according to the mitochondrial genomes of other Gelidiales using the trial version of Geneious R11.12 software. The plastid genome was also selected following the same approach but using plastid genomes of Gelidium elegans and Gelidium vagum as search queries. Gaps observed in the organellar genomes were closed by amplification of the relevant gap using polymerase chain reaction with newly designed primers and Sanger sequencing. Open reading frames for both organellar genomes were annotated using the NCBI ORF-Finder and alignments obtained from BlastN and BlastX searches from the NCBI database, while the tRNAs and rRNAs were identified using the tRNAscan-SE1.21 vi and the RNAmmer 1.2 servers. The circular physical map of the mitochondrial genome was constructed using the CGView server. Lastly, in silico analysis of cytochrome c oxidase 3 and Heat Shock Protein 70 was performed using the PRIMO and the SWISS-MODEL pipelines respectively. Their phylogenies were analysed through Clustal omega and the trees viewed on TreeView 1.6.6 software. Qubit and Nanodrop genomic DNA qualification revealed A260/A280 and A230/A260 ratios of 1.81 and 1.52 respectively. The 1% agarose gel electrophoresis further confirmed the good quality of the genomic DNA used for library preparation and sequencing. Pre-assembly quality control of reads resulted in a total of 30 792 074 high-quality reads which were assembled into a total of 94140 contigs, making up an estimated genome length of 217.06 Mb. The largest contig covered up to 13.17 kb of the draft genome, and an N50 statistic value of 3.17 kb was obtained. The G.pristoides mitochondrial genome mapped into a circular molecule of 25012 bp, with an overall GC content of 31.04% and a total of 45 genes distributed into 20 tRNA-coding, 2 rRNAcoding genes and 23 protein-coding genes, mostly adopting the modified genetic code of Rhodophyta. The SecY and rps12 genes overlapped by 41 bp. This study presents a partial plastid genome composed of 89 (38%) fully annotated genes, of which 71 are protein-coding, and 18 are distributed among 15 tRNA-coding, 2 rRNA-coding and 1 RNaseP RNA-coding genes. Sixty-one (26%) partial protein-coding genes were predicted, while approximately 84 (36%) genes are not yet predicted. In silico analysis of the cytochrome c oxidase and heat shock protein 70 showed that the gene sequences obtained in this study and the resultant transcribed protein have sequences and structures that are similar to those from several other different species, thus validating the integrity of the genome sequences. This study provides genomic data necessary for understanding the genomic constituent of G.pristoides and serve as a foundation for studies of individual genes and for resolving evolutionary relationships.

Pre-assembly quality control of reads resulted in a total of 30 792 074 high-quality reads which were assembled into a total of 94140 contigs, making up an estimated genome length of 217.06 Mb. The largest contig covered up to 13.17 kb of the draft genome, and an N50 statistic value of 3.17 kb was obtained. The G.pristoides mitochondrial genome mapped into a circular molecule of 25012 bp, with an overall GC content of 31.04% and a total of 45 genes distributed into 20 tRNA-coding, 2 rRNAcoding genes and 23 protein-coding genes, mostly adopting the modified genetic code of Rhodophyta. The SecY and rps12 genes overlapped by 41 bp. This study presents a partial plastid genome composed of 89 (38%) fully annotated genes, of which 71 are protein-coding, and 18 are distributed among 15 tRNA-coding, 2 rRNA-coding and 1 RNaseP RNA-coding genes. Sixty-one (26%) partial protein-coding genes were predicted, while approximately 84 (36%) genes are not yet predicted. In silico analysis of the cytochrome c oxidase and heat shock protein 70 showed that the gene sequences obtained in this study and the resultant transcribed protein have sequences and structures that are similar to those from several other different species, thus validating the integrity of the genome sequences. This study provides genomic data necessary for understanding the genomic constituent of G.pristoides and serve as a foundation for studies of individual genes and for resolving evolutionary relationships.

- Description: Tuberculosis is an epidemic disease which is regarded as the tenth leading cause of death in the world (World Health Organization, 2014). New 580 000 cases of multidrug resistant tuberculosis have been reported by WHO (2014). Patients diagnosed with rifampicin/multi-drug resistant tuberculosis were usually treated for 18-24 months if they convert within the designated period of 4-6 months. Several trials were conducted in other countries like Burundi, Cameroon, Central African Republic, etc. on the use of short regimen of 9-12 months. Short regimen was introduced in January 2017 in South Africa and it has not been evaluated for its effectiveness in Buffalo City Metropolitan, South Africa. This study was conducted to examine RR/MDR TB outcomes following the introduction of a short regimen and the outcomes were based on the set target of 50% MDR TB success rate and 5.4% TB client lost to follow up rate as per the Annual Performance Plan (APP) of 2017/18. The conversion rate was also examined though the target was not set in APP. A retrospective study using a descriptive design was used to collect data at Nkqubela TB and Duncan Village Day hospitals which are in Buffalo City Metropolitan. The population of the study were all records of patients diagnosed, registered and initiated on rifampicin/multi-drug resistant TB in a short regimen in Nkqubela TB Hospital and Duncan Village Day Hospital between January 2017 and July 2017. All 118 patient records that met the inclusion criteria were enrolled in the study therefore convenience sampling was used. Ethical approval was obtained from the University of Fort Hare (ethical clearance number: MUP101SSOM01). Approval to conduct the study was also approved by the Eastern Cape Department of Health Ethics, BCM Health District Manager and two public hospitals. Two research assistants and one data capture signed oath of confidentiality prior data extraction. Unique codes were used to ensure anonymity and privacy and all data was treated in a confidential manner. Data was collected using a self-designed structured questionnaire which was tested for validity and reliability through pilot study. Data analysis was done by a statistician using Statistical Packages for Social Sciences version 24. RR/MDR TB outcomes of participants who were initiated on short regimen between January and July 2017 were examined between January and July 2018 at the end of 12 months. Findings showed that the majority of the affected age group was between the ages of 36-45 years in both genders (34.7%) with males (n=71) being highly affected than females (n=47). Bisho/King William’s Town sub-district was the most affected in Buffalo City Metropolitan (n=61). The majority of participants that were affected were the Africans (98.3%), unemployed (51.7%), people living with HIV/AIDS (62.7%) and those previously treated for TB (57.6%). Records revealed that participants living with HIV had a mean CD4 count of 194.5 and 202.4 and mean viral load of 203183.0 and 651888.7. Smokers and alcohol users were higher in males (20.3% and 16.9% respectively) than in females (2.5% and 5.1% respectively). Two patient records were missing and other four patient records were incompletely recorded to determine data on smoking and alcohol consumption. Findings revealed a smear conversion rate of 68.5% excluding 47 participants who had negative baseline smear results and one participant who had extra-pulmonary TB. Twenty one percent of the participants did not have consecutive smear results during the intensive phase. TB client lost to follow up rate was 13.5% (n=16) and 10 of all TB clients lost to follow up interrupted treatment for ≥5 months. Eleven TB clients lost to follow up were from Buffalo City Municipality Metropolitan. TB client lost to follow up was high in males (n=13). Rifampicin/multidrug resistant TB treatment success rate was 72.9% with mean response to treatment of 17.2 weeks. Weight (p0.005 and CI 2.750, 15.189) and body mass index (p0.004 and CI 1.232, 6.242) as well as duration of treatment interruption (p0.000 and CI -14.785, -8. 644) and duration of treatment (p0.001 and CI -65.385, -16.403) were statistically significant to treatment success. Based on these findings, it is therefore concluded that short regimen is effective in the management of RR/MDR TB despite high TB client lost to follow up rate. Decentralisation of drug resistant TB management; primary health care reengineering; use of NIMDR-trained nurses; tracing of TB interrupters; HIV management; electronic patient management system and review of how EDR register works; proper record keeping and proper recording; extensive and ongoing counselling, patient support, health education and patient monitoring; and political involvement; is recommended. Further research is recommended to identify patient and service related factors that affect TB treatment outcomes.

- Description: Social media is 21st century phenomenon has captured the attention of millions of people across the globe and has hitherto, permeated through all facet of our contemporary life. It has become the important conduit through which people far and near interact. Sharing of information, communicating, collaborating, engaging are some of the visible highlights of Social Media. Social media usage cut across different demographics. This is due to the unique characteristics of social media which includes openness, participation and sharing. The purpose of this study is to investigate the impact such usage have on less advantaged communities and how it can be used to further their cause in achieving socioeconomic parity. This study is qualitative in nature and it relied on semi-structured interviews and observations to collect data. Purposive and convenience sampling was used to select respondents. The findings of the study indicate that utilizing social media for the utmost gain is imperative in that the presence of new technologies has revolutionised the way people socialise beyond real time and boundaries. It was also noted that social media is the new norm as such societies far and beyond need to harness the potential not only for the social media generation but for the communities within its reach. Thus, researching into the impact this phenomenon has on the poorest communities is of great importance for both the public and policy makers. This study however recommends regulation of social media in order to contain security risks that it poses. It is therefore important to enhance internet security to protect the privacy threats. It is also important to invest more on issues of information and communication technology on low-income communities

- Description: Lithological mapping of areas is crucial for both mineral resource identification and determination of ore concentrations. Without adequate knowledge on the extent of an area’s lithology, the above applications cannot be meaningfully accomplished. Spectroscopy-based mapping of rocks involves the use of portable reflectance spectrometers and digital maps to analyze, assess and map changes in rocks. Thereafter, understand and interpret the geochemical, physical and environmental processes that have an impact on the reflectance of the rocks while also making spatial and spectral links. Mapping lithology using remote sensing involves identification of rocks in remotely sensed images with lithological mapping being achievable through field and laboratory spectroscopy and creation of a spectral library. The main goal of this study was to measure, extract and analyze spectral signatures of dominant rocks within the Balfour Formation in order to create a spectral library that is capable of enabling, fast and cost-effective mapping of the spatial distributions of rocks within the Balfour Formation. The spectra of dominant rocks of the Balfour Formation were measured using the SR 3500 spectroradiometer. Different pre-processing techniques were applied to the acquired spectra such as smoothing, scatter correction and outlier detection. Random Forest classifier was used in the classification of the different rocks. Analysis of Variance and Bonferroni post hoc test were applied on the spectral signatures of different rocks to ascertain if there were any spectral differences between the absorption features in the spectra of the rocks. Landsat 8 imagery was used for classification of the different rocks within the Balfour Formation, maximum likelihood and spectral angle mapper were the two classifiers that were XI used. Maximum likelihood presented an accuracy of 76.19 % and 66.67 % for spectral angle mapper.

- Description: The purpose of this study was to explore students’ perceived experiences of flipped classrooms at a traditional South African university in comparison to the traditional classroom. Universities across the world are confronted with a variety of problems. One of these challenges include the massification of higher education as more students now have access to universities resulting in larger class sizes and lower through put rates. Universities have traditionally made use of the face-to-face model of lectures and tutorials as a passive mode of course instruction and delivery. However, due to the massification of higher education, it has become very difficult for lecturers to communicate and collaborate with students. One of the ways that lecturers have attempted to overcome the problem of massification is to make use of technology to increase the delivery of course content. When lectures are made available online while the traditional class time is used to build conceptual understanding and cognitive skills among students, the approach is known as ‘flipping’ the classroom. Several studies have shown that this type of active classroom approach can perform better than traditional lectures when learning outcomes are compared. There is also a very limited body of knowledge available regarding students’ perceived experiences of flipped classrooms at traditional South African universities. The theoretical frameworks guiding this study are the Activity Theory and Constructivism, whilst a pragmatic paradigm was employed. The flipped classroom was used in one course of the Management and Commerce Faculty at a traditional university in South Africa. The study was divided into three cycles: The first cycle involved 4 weeks of traditional lectures, the second cycle of 4 weeks introduced blended learning into the course, while the third cycle of 4 weeks changed the content delivery method to a flipped classroom. At the end of each cycle a formal evaluation through focus groups interviews (with 10 students per cycle) and a questionnaire (that was administered to the class) was conducted to inform the next cycle. Throughout the research process, the researcher also kept detailed field notes to as an account of the planning, execution and reflection for each class. The researcher also observed the behavior of the students during the various research cycles to provide a ‘snapshot’ of the classes. The results of the study suggest that students prefer the use of the flipped classroom is it enables them to communicate with their peers and the lecturer, and providing them with opportunities to better understand learning content through discussions and reasoning, rather than the means of receiving information. Barriers that were identified included difficulty with learning strategies and technical assistance when students needed assistance. However, students were positive about both the use of the flipped classroom as opposed to the use of the traditional classroom.

- Description: The purpose of the study was to explore the effects of substance abuse on the academic performance and professional behaviour of students at a public nursing college in order to develop guidelines for the prevention of substance abuse. The design that was chosen as most suitable for this study was the qualitative research design. The researcher chose this method as she sought to explore the effects of substance abuse on the participants in this study. A purposive sampling method was used to select participants on the basis of their knowledge of the phenomenon.The participants who were utilised were 3rd and 4th year level students in the four year diploma in nursing. A pilot study was conducted and participants with similar characteristicsto the study population were utilised. Individual interviews were used as the means to collect data during which participants were given an opportunity to discuss issues with the intention of eliciting their views and opinions. One broad, open ended question was used to gather information from the participants and subsequent questions were used to probe further for clarity. Data were collected until saturation pointwas reached. Transcriptions were done within two days of the interview. The researcher repeatedly listened to audio recordings of the data until completely satisfied with verbatim interpretation of data. Data analysis was done manually. The researcher used the process of bracketing during data analysis and remained neutral, setting aside previous knowledge and beliefs about the phenomenon under study. The participants were allowed freedom to conduct their lives as autonomous agents, without control, coercion or exploitation. The findings revealed that: firstly, substance abuse has a negative impact of on both the academic performance and professional behaviour of the public nursing college students; secondly, that guidelines are needed for the prevention of substance abuse amongst students so as to focus on a ‘substance abuse free college environment’. vi The academic performance is negatively affected as substance abuse results in cognitive impairment, failure to meet the 85% lecture attendance requirement resulting in them repeating a year of study or being excluded from the course, and resulting in a missed opportunity to acquire scientific knowledge in nursing. The students’ academic aspirations get derailed. Students also experience strained relationships with lecturers due to drunkenness and bunking classes. Studentlecturer strained relationships are incompatible with academic achievement. Students whose professional behaviour is negatively affected by substance abuse demonstrate unethical conduct and professional misconduct in the clinical setting for experiential learning. The students fail to inculcate the values of the nursing profession and thus tarnish the image of the profession. Such students behave unprofessionally as they either absent themselves from duty, come on duty drunk or continue taking substances while on duty. They are also rude and swear at colleagues, supervisors, other staff members and patients. The students steal from colleagues and display insubordination. Their dress code is unprofessional and they are incompetent with poor standards of care towards the patients. The purpose of this study was to develop guidelines to prevent substance abuse at the college and this has been achieved. The results show that the college environment should be made substance abuse free by: firstly, identifying and mitigating the predisposing factors or reasons for substance abuse, for example: establish a proper and aesthetic infrastructure conducive to learning and teaching at the students’ residences and classrooms, set up mentorship programmes and introduce the house-mother model at residences; secondly, developing a policy on prevention of substance abuse within college premises including disciplinary measures; thirdly, developing stress management programmes for students to prevent abuse of substances as a coping mechanism, e.g. decongest the curriculum, curriculum review to be consultative, develop support groups, grant mid-year breaks and provide recreational and sporting facilities; fourthly, engage the services of a vii professional therapist for students who are already abusing substances or referral to the therapist; fifthly, clinical accompaniment should be strengthened for effective correlation of theory and practice; and, lastly, engage the services of a financial advisor to give guidance on income and expenditure with regard to student stipend instead of spending it on substances.

- Description: Eight new oxovanadium(IV) dithiocarbamate complexes, formed by the interaction of vanadyl sulfate pentahydrate and as-synthesized dithiocarbamate ligands, potassium N-morpholine-4- dithiocarbamate ligand (L1), potassium N-piperidinedithiocarbamate (L2), potassium N-(4- methoxyphenyl)dithiocarbamate ligand (L3), potassium N-diallyldithiocarbamate ligand (L4), potassium N-phenyldithiocarbamate ligand (L5), potassium N-dibenzylminedithiocarbamate ligand (L6), potassium N-(4-methylphenyl)dithiocarbamate ligand (L7), N-(1Himidazoledithiocarbamate) fluoride ligand (L8) in aqueous ethanol are described. The resulting complexes were elemental analyses, molar conductance, infrared, electronic, and nuclear magnetic resonance spectral studies. The spectral studies confirmed the formation of the ligands and complexes. Four complexes [VO(L1)2], [VO(L3)2], [VO(L6)2], and [VO(L8)2] derived from potassium N-morpholine-4-dithiocarbamate ligand (L1), potassium N-(4- methoxyphenyl)dithiocarbamate ligand (L3), potassium N-dibenzylminedithiocarbamate ligand (L6), and N-(1H-imidazoledithiocarbamate) fluoride ligand (L8) were characterized using cyclic voltammetry, to study their electrochemical behavior. Square pyramid oxovanadium(IV) complexes were proposed with the metal ion coordinated to two bidentate dithiocarbamate ligands through sulphur to complete its square pyramidal geometry. The anticancer screening of four oxovanadium(IV) dithiocarbamate complexes [VO(L1)2], [VO(L3)2], [VO(L6)2], and [VO(L8)2] are described.

- Description: he focus of this research was to synthesize and characterize carvacrol hybrid analogues. Twenty-one (21) carvacrol analogues were synthesized by reacting carvacrol with (1. 4- aminosalicylic acid, 2. ferrocene keto-butanoic acid, 3. Ferrocene butanoic acid, 4. succinic anhydride, 5. folic acid, 6. cinnamic acid, 7. leucovorin, 8. oleanolic acid, 9. artesunate, 10. cholesterol, 11. cholesterol succinate, 12. curcumin, 13. curcumin succinate, 14. zidovudine, 15. Zidovudine succinate, 16. 8-hydroxyquinoline, 17. 8-hydroxyquinoline succinate, 18. 2- (7-chloroquinolin-4-ylamino)ethyl 5-isopropyl-2-methylphenyl, 19. 2-(7-chloroquinolin-4- ylamino)ethyl 5-isopropyl-2-methylphenyl succinate, 20. 2-(2-(7-chloroquinolin-4- ylamino)ethoxy)ethyl 5-isopropyl-2-methylphenyl, 21. 2-(2-(7-chloroquinolin-4- ylamino)ethoxy)ethyl 5-isopropyl-2-methylphenyl succinate). The carvacrol analogues were characterized using FTIR, UHPLC-HRMS, 1H- and 13C-NMR spectroscopy. The antibacterial analysis was performed to evaluate the carvacrol analogues against bacterial strains. FTIR spectra of carvacrol analogues were found to exhibit peaks of C-O stretch and Ar-C in a range of 1014-1280 cm-1 and a range of 1414-1697 cm-1 which confirm the successful formation of esters. The proposed structures of carvacrol analogues were confirmed by the 1H- and 13C-NMR. The selected 1H-NMR signal for aromatic protons ranged at 6.00-8.95 ppm/δ. The selected 13C-NMR signal for ester carbon and aromatic carbons ranged at 160.0-175.0 ppm/δ and at 110.00-154.00 ppm/δ. The structures were also confirmed by UHPLC-HRMS. Carvacrol analogues exhibited the highest inhibitory effect against Gram-positive and Gram-negative tested bacterial strains.

- Description: Human capital is considered as the measure of education, skills, capacity and attributes of labour which impact people’s productive capacity and earning potential. The study used mathematics student academic performance as a proxy to measure human capital across countries using the Trends in International Mathematics and Science study (TIMSS) dataset. African countries participating in TIMSS are performing poorly as they are always at the bottom. The budget allocation of African countries is more than that of Asian countries, but the student outcomes do not correlate with the input. This is so disappointing considering the amount of money the governments invest in the education sectors. The study investigated teacher practices and human capital acquisition in four African countries that participated in TIMSS from 2007 to 2015. The four countries were South Africa, Botswana, Egypt and Morocco. In addition, the study included the best performing countries from East Asia that also participated in TIMSS. These four countries were Singapore, South Korea, Japan and Hong Kong Sar. The best performing countries were included in the analysis in order to determine best practice from the best performing countries. Using Stata 14, pooled OLS cross sections methodology was used to generate results on whether teacher practices influence students’ mathematics achievement by using grade 8 test scores per country, student and teacher background. The study found that some teacher practices significantly explain academic performance in mathematics especially in African countries whilst socio economic status significantly affect performance across all the countries. Future research will investigate some other measures that can promote good performance of mathematics in African countries.

- Description: The study aimed at examining teachers and learners’ perspectives towards English as a language of learning and teaching (LoLT), using two selected secondary schools in the Amathole West Education District as a case study and to see if English is indeed a language of choice among learners and teachers. The researcher employed an interpretative qualitative research paradigm and purposive non-probability sampling method was used to draw samples of participants for in-depth interviews and focus group discussions. The school principal and two teachers were purposively selected in each of the two schools, making a total of two school principals and four teachers that were interviewed. In addition, a member of the School Governing Body (SGB) was selected in each of the two schools and interviewed. The study also had one focus group discussion with learners in each of the two selected schools, making two focus groups in total. All the one-on-one in-depth interviews as well as the focus group discussions with the learners were recorded and then transcribed. The collected data was later analysed thematically to infer the meaning and present the findings. The findings revealed that most of the students in public schools are torn between two divides as they struggle with the use of English as a language of learning and teaching but seem to have no choice, as they all believed that the use of English is quite beneficial to them in many ways. Another critical finding is that some teachers find it difficult to teach in English because they do not have a good command of the language. This makes them to code-switch regularly using IsiXhosa along with English while they are supposed to teach in English. Thus, this affects the learners proper understanding of and grounding in the English language. The study also found out that the schools lack adequate support to ensure the effective use of English for learning and teaching. The study recommended that various support systems from the government are needed in order to ensure the acceptance and successful use of English as LoLT in South African public schools. In this regard, the participants assured that these would result in positive outcomes, as they would provide quality education through government support. The study concluded that English is the preferred LoLT by both teachers and learners, thus, it needs to be prioritised.

- Description: The study focuses on teachers’ perception of the integration of environmental education into grade 12 curriculum in East London education district. This study is based on empirical research. The theoretical framework of the study is based on Opportunity to Learn (OTL). The concept of OTL was formulated by international Association of Achievements (McDonnell, 1995).OTL is multiplicity of factors that create the conditions for teaching and learning, such as curricula, learning materials, facilities, teachers and instructional experiences. The research study is supported by national and international literatures based on environmental education and integration of environmental education as a component in the school curriculum, and policy documents. The study adopted qualitative research approach, using phenomenological method and interpretivism paradigm respectively. The empirical data was collected from one high school in Mdantsane Township in East London education district. The study sample consisted of 6 high school teachers. Data was collected through semi- structured interviews. According to the findings of the research, grade 12 teachers expressed disparities in their perceptions of environmental education as an integrated component into their subjects. Most of the subject teachers focused on the aspect of knowledge acquisition. According to South African education system, environmental education (EE) has been integrated into all subjects. Although there is environmental education in the GET and FET phase curriculum respectively, however it is not integrated evenly in all subjects. Some subjects like Life sciences, geography have more environmental content than other subjects. Teachers suggested that the approach adopted to integrate environmental education into the school curriculum was not favourable because teachers claimed that what is to be taught as environmental education in the various subjects is not indicated explicitly in the CAPS document. The CAPS document prescribes EE integration into all subjects which makes the teaching of EE a collective responsibility. The main actors of EE integration implementation are themselves a constraint to the success of the integration. The teacher is confronted with many challenges in the process of environmental education integration. This includes lack of teaching and learning resources, time and large class size. The role of teachers in the implementation of environmental education in developing an environmentally literate citizenry is of great significance. The responsibility of the government in ii developing a curriculum with clear goals and content, developing teachers’ capacity in the teaching of environmental education and provision of teaching and learning materials needs to be taken seriously by the government in educational plans and programs. Topics for future research on the integration of EE into grade 12 curriculums were suggested in order to improve on teaching and learning of environmental education

- Description: The purpose of this study was to investigate the views of Teachers about reading comprehension skills in grade 7 English Additional Language classrooms in Buffalo City Metropolitan, Eastern Cape. Objectives are to instil the love for reading and enabling learners to successfully learn to read and attain their full potential. The researcher was interested in exploring broader trends in reading comprehension skills, with the intention of contributing possible strategies to address the literacy level in English First Additional Language. The study was framed as qualitative in inquiry; a face-to-face semi-structured interview was used to collect data. The participants comprised of 24 learners and 4 educators. The theoretical framework utilised was Lev Vygotsky’s (1979) constructivist theory to analyse data using a qualitative analysis approach. Different tools to verify data, which comprised of semi- structured interview of open-ended questions and document analysis to obtain data from English First Additional Language teachers in four primary schools in the Buffalo City Metropolitan District, were used. Findings indicate English First Additional Language learners are not proficient in the language of teaching and learning because in other public schools mother tongue is additive language, while in other schools it does not exist. The recommendation was that the Department of education needs to introduce a reading module for English First Additional teachers who need training in this area of learning. Another recommendation highlighted by teachers is the revisiting of child development theories that will help teachers have a better understanding about the learners and which strategies to utilise during reading.

- Description: Aggressive behaviour among student athletes is often expressed dramatically in both males and females participating in sports. This expression of aggression may have a negative effect on their game during play as well as their psychological well-being. Being either verbally aggressive or physically aggressive during sports has social, economic and psychological consequences, which include changes in character. However, very few international studies and no South African study could be found during a literature search that addressed group differences in the life- and sport aggression among student athletes in contact, non-contact, and collision sports, and gender groups, particularly among varsity sport athletes. Consequently, the aim of this study was to investigate the differences between life- and sport aggression among student athletes in five different sports codes, categorised as collision sport (rugby), contact sport (soccer), and non-contact sports (cricket, netball, basketball), as well as gender differences at a rural university in the Eastern Cape Province, South Afric

- Description: This dissertation discusses the involvement of a community in creating development opportunities for youth in Indwe, under Emalahleni Local Municipality in the Eastern Cape. Establishing a position where community members put themselves concerning youth development is what inspired the study. The study is further motivated by trying to gain perspectives from the youth because most discourses on youth rarely feature their voices. Additionally, it seeks to gain perspectives on the stakeholder’s insights on the involvement of the community in youth development. The literature consulted was broken up into; the situation of youth in South Africa, which looked at youth unemployment and youth development policies; youth development, which looked at risk and protective factors that affect youth development. The literature further uncovered the role currently played by communities in youth development, and lastly the multi-stakeholder processes for youth development. The Quintuple Helix model was a framework used to shape this study. This framework emphasises that the natural environment and in this case, the community be added to other stakeholders to ensure a sustainable youth development. What is crucial in the framework is the overlap and cross-communication between the different helixes or sectors, sectors such as the university, the government, the private sector, the culture based media, and the natural environment. The study utilised a qualitative methodology with an interpretive and descriptive paradigm, which used focus groups and a qualitative questionnaire as a method of data collection. The data was analysed and presented following the following three themes; i.e., community involvement in youth development, indigenous knowledge for youth development, and opportunities for youth development. The findings of the study revealed that, if Indwe community provides youth with more spaces, and chances to participate in their development, the youth could challenge prominent discourses than treat them as unmotivated, and exclude them from decision-making processes, which directly affect them, and the society within which they live. The findings also revealed that the Indwe community should inform youth iv development programmes, as this would ensure sustainability, and give a sense of ownership to the community. The findings further indicated that the Indwe community could utilise its natural resources to create opportunities for youth development. Moreover, the private sector, the media, and the education system have all contributed in youth development; however, the government has taken full responsibility for youth development in Indwe, and this caused the participants to feel that it is the government’s responsibility to create opportunities for youth development. In conclusion, Indwe community has a challenge of youth development. The problem is fuelled by issues such as complexity in politics, nepotism, and a lack of opportunities. Stakeholders such as the private sector, the media based culture, and the government are involved in the creation of development opportunities for youth in Indwe. However, the sector that has taken the most responsibility for the development of youth is the government. Indwe community members are not involved in the creation of opportunities for youth development; they, however, understand that they have to be significant role players.

What is crucial in the framework is the overlap and cross-communication between the different helixes or sectors, sectors such as the university, the government, the private sector, the culture based media, and the natural environment. The study utilised a qualitative methodology with an interpretive and descriptive paradigm, which used focus groups and a qualitative questionnaire as a method of data collection. The data was analysed and presented following the following three themes; i.e., community involvement in youth development, indigenous knowledge for youth development, and opportunities for youth development. The findings of the study revealed that, if Indwe community provides youth with more spaces, and chances to participate in their development, the youth could challenge prominent discourses than treat them as unmotivated, and exclude them from decision-making processes, which directly affect them, and the society within which they live. The findings also revealed that the Indwe community should inform youth iv development programmes, as this would ensure sustainability, and give a sense of ownership to the community. The findings further indicated that the Indwe community could utilise its natural resources to create opportunities for youth development. Moreover, the private sector, the media, and the education system have all contributed in youth development; however, the government has taken full responsibility for youth development in Indwe, and this caused the participants to feel that it is the government’s responsibility to create opportunities for youth development. In conclusion, Indwe community has a challenge of youth development. The problem is fuelled by issues such as complexity in politics, nepotism, and a lack of opportunities. Stakeholders such as the private sector, the media based culture, and the government are involved in the creation of development opportunities for youth in Indwe. However, the sector that has taken the most responsibility for the development of youth is the government. Indwe community members are not involved in the creation of opportunities for youth development; they, however, understand that they have to be significant role players.

- Description: In South Africa, nearly a third of women have children before they reach the age of 20, and basic education is compulsory until the age of 16. Many learners within the South African context continue to attend school until they are at least 20. Of all those teenage girls who fall pregnant, it is estimated that only around a third stay in school during their pregnancy and return following childbirth, with the highest return rate among those in Grade 12. As a result the government is committed to enforcing legislation and policy that protects and allows for pregnant learners to exercise their rights. The rationale of the study focuses on the fact that, rights-based documents are often at odds with the hierarchical spaces within schools. In practice, teachers and school managers continue to have the power to exclude pregnant learners. Although there is excellent legislation and progressive policy, these documents do not address the larger ideological landscape that impacts on the successful implementation of policy. Often policy is contradictory, ambiguous and draws on very conservative discourse. The aims of this study were to analyze the positioning of the pregnant learner within legislation and policy. A qualitative framework utilizing positioning theory was adopted in order to understand how the pregnant learner is positioned and constructed within relevant policy and legislation. This was accomplished by critically analyzing the discourses used within policy in order to tease out various themes or discourses, for example the pregnant learner as an ‘unfit mother’, as responsible, or as rights bearing etc. This was done in order to understand how the pregnant learner is positioned and what the implications of this positioning impose upon her life. The analysis suggests that pregnant learners are positioned as shifting ‘subjects’ in order to achieve very specific aims. The study established that their rights are not always absolute but contingent on other factors, that she is positioned as transitional, vulnerable, and rights-bearing and expected to be responsible. It is recommended that these policies be amended through a process of engagement with teachers and school management in order to ensure the rights of pregnant learners in schools.
