- Description: This study investigated the implementation of Professional Development Programmes for Grade R teachers in four primary schools in Amathole West Education District. The interpretive paradigm was employed in this study because it focused on the teachers’ professional development and their participation in a social learning interaction as community of practice. Furthermore, a qualitative approach was used for the collection of data so as to gain in-depth information on the implementation of professional development programmes. Semi-structured interviews and document analysis were used as a form of collecting data. The participants were purposively selected for the sample of this study and comprised of 4 Principals, 1 Subject Advisor and 4 Teachers. Data analysis was done in line with the research questions, aims and objectives of the study. Through the participants’ answers from schools under study, a transcript was formulated, coded and categorized in view of the implementation of Professional Development Programmes for Grade R teachers. The data revealed that Grade R teachers under study were under qualified such that none of the teachers had the recommended Diploma in Grade R qualification as stated by the Department of Basic Education. It was also found that there was diversity in the teachers’ qualifications, colleges and the length in training. The study also indicated that although professional development programmes were held, these were however not properly monitored. Findings also revealed that the intervention strategies through professional development programmes and the support given by the district and the schools were strategies through professional development programmes and the support given by the district and the schools were not adequate and consistent. As a result the participants encountered a number of challenges regarding the implementation of professional development programmes for Grade R teachers. Namely: (1) lack of appropriately qualified personnel to support the teachers both at school and the district (2) lack of adequate follow up support visits and feedbacks from both the school and the district (3) lack of proper management by the schools and (4) lack of collaboration ii and team work in the schools. Thus, there were variances in schools under study especially with regards to late release of funding for teaching and learning materials, support offered to the principals by the Department of Education. As a result, recommendations from the study suggested that the Department of Education and the District have to come up with more strategies of continuously training the teachers and the principals and offering strong and adequate support. The study also recommended the engagement of NGOs for job embedded professional development with longer in-service training periods as compared to the shot in-service professional development programs of once- off workshops. Also another suggestion that the district must monitor school based professional development programs regularly was raised in the study

- Description: Food security situation in Zimbabwe is deteriorating despite the efforts made by the government for embarking on agrarian reforms in terms of redressing colonial imbalances and taking on the major trading investment risks. The government assured the resettled farmers that if they invest in maize production, they would not be stranded by lack of marketing services as the markets are liberalized. However, this market liberalization policy occurring in maize sector has resulted in A1 resettled farmers becoming more vulnerable to traders preying on their weaknesses as the policy is not living up to expectations and is failing to bring dramatic increases in agricultural growth. This may mean that sending children to school is a nightmare for those who depend on farming for educating their children, inadequate food in the home, unpaid loans and subsequent impoverishment. The resettled A1farmers will remain trapped in the poverty cycle as long as institutions are not corrected. The general aim of the study was to evaluate institutional factors influencing maize production and marketing by A1 resettled farmers of Marondera district in Mashonaland East province of Zimbabwe. Using a sample of 343 farmers randomly selected in Marondera District, different econometric models like Data envelopment Analysis, Cob Douglas, Binary logistic, and Tobit as well as descriptive statistics were used to analyse the data. Institutional variables were captured in two ways: as a dummy showing whether farmers have access to institutional variables and as a continuous variable indicating importance of institutions on maize production and marketing. The study found out that, most of the A1 farmers are old, with a mean age of 47 years and a maximum of 55 years of farming experience. It is also dominated by male farmers who are literate. Results also showed that most of A1 farmers from the sample are married and very few separated. These farmers sell most their maize and keep little for consumption though they are still using convectional farming methods. Most of the farmers from the sample generate their incomes from farming activities only and they have good access to market and production information as well as extension xvi messages through training .They however have poor access to financial credit and weak social capital as well as low contract farming. Results also indicated that A1 farmers pursue the formal supply chains than informal supply chains. It is noted that, A1 farmers participate in a number of markets that include agricultural inputs markets seed, fertilizers, chemicals.; credit markets which includes banks as well as labour markets which can in the form of (maricho). In terms production and marketing efficiency, the study found out that A1 farmers are technically, allocatively and economically inefficient. The maximum efficient score is 1 while the minimum score is 0.01 for both production and marketing stage. The mean scores for production stage are 0.195, 0.504 and 0.072 for technical, allocative and economic efficient respectively. The mean scores for marketing are 0.103, 0.688, and 0.068 for technical, allocative and economic efficiency respectively. Farmers are performing better at production stage than at marketing technically while there is better allocative and economic efficiency at marketing stage. Results for determinants of technical, allocative and economic efficiency at production stage showed that, cattle ownership, farming experience, access to financial credit and (member of farmer organisation) which was used as a proxy indicator for social capital ,access to information, contract farming, distance to input market ,area planted to maize and quantity of seed used influences marketing efficiency of A1 maize farmers in Marondera District. Access to credit, Access to market, distance to market, road infrastructure, farming experience and access to information influences technical, allocative and economic efficiency at marketing stage. Cooperative membership, road infrastructure, contractual farming arrangements, and access to financial credit and transport cost to market influence choice of marketing channel respectively. Finally results from the non linear cob Douglas reveals that, maize production is significantly influenced by contract with value chain actors, access to market xvii information, access to financial credit, total topdressing used , total basal fertilizer used, total herbicides used, and total area put under maize production. The results showed that, future of A1 resettled farmers depends on correcting the institutions which are of paramount importance for maize production and marketing. The study therefore recommended the government to improve institutional environment that has direct link with institutional innovations necessary for sustainable maize production and marketing. This can be done through correcting inefficiencies and ineffective institutions by creating and maintaining both environment and arrangement that will transform maize production and marketing systems to operate efficiently. The study presents policy options to address both production and marketing of maize arguing that new direction of production and marketing of maize depends on correcting dysfunctional institutions. Policy options include increasing A1 farmers access to financial credit by removing the stringent collateral requirements which are not attainable by most A1 farmers as their asset endowment is limited to non capital. Addressing imperfections in the input markets by improving the supply of chemical fertilisers and seed at affordable prices as this influences total area put under maize production. The other policy is for private companies and NGOs to offer contract farming to A1 maize farmers as this will help them to increase total area put under maize production, access to market, access to credit, and access to information and reduces long distances to purchase inputs. Introducing focused training to motivate resettled A1 farmers on formation farmer organisations as this assists in social capital which is an important asset in maize production and marketing.Improving road infrastructure by creating a fund that would be used to maintain the road rather waiting for DDF only.

- Description: Lack of access to essential medicines has proven to be a persisting problem which is in conflict with the goal of realising the right to health envisaged by the South African constitution and international human rights instruments. With more than twenty years of democracy, South Africa is still plaguing with a multiplicity of pandemics such as HIV and AIDS, cancer, malaria, tuberculosis, among others, leading to premature death and untold suffering of the people. According to a 2015 United Nations AIDS (UNAIDS) Gap report, South Africa is still regarded as the epicentre of HIV and other infectious diseases. The 2015 UNAIDS Gap report states that South Africa has more women than men living with HIV and AIDS. The report further indicates that the impact of this pandemic is worsened by the inaccessibility of essential medicines that are vital for life saving. This dissertation posits that the epidemiological health crisis described above can be largely eradicated through the utilisation of the right to health. The right to health, according to this dissertation, contains a legal and transformative power which can be utilised to limit the negative impact of patent laws on access to essential medicines in South Africa. This dissertation validates the long held view that World Trade Organisation (WTO) intellectual property laws have contributed to the inaccessibility of essential medicines through causing patent ever greening, patent linkages and pharmaceutical company’s monopolies. Consequently, many marginalised groups in South Africa lack access to essential medicines owing to the higher prices charged for such medicines thus violating the right to health, life and other fundamental human rights. The right to health which is the immediate right infringed when there is lack of access to essential medicines form the core theme of this dissertation. This dissertation argues that access to essential medicine is a fundamental part of the right to health protected under international and national human rights instruments. This dissertation further argue that the right to health imposes obligations which requires South African government to take reasonable legislative and other measures, within its available resources, to provide access to essential medicines. The dissertation‘s key contribution is its proposed solutions on how to ensure that patents rules in South Africa are tamed with obligations consistent with the right to health. If properly implemented, these solutions have the potential to give greater specification to the normative commitments imposed by the right to health in the patent claims scenarios.

- Description: Access to clean and safe water is essential for the survival of human beings. Nevertheless pollution from wastewater treatment plants (WWTPs) effluents often impacts the microbiological qualities of surface waters. Availability of freshwater resources is indispensable for preventing waterborne diseases. The current study evaluated the physicochemical properties and abundance of Vibrio species in selected rivers and WWTPs in the Eastern Cape Province of South Africa, over a one year sampling regime (December, 2016 to November, 2017). Water samples were collected monthly at designated locations along the banks of two rivers, treated effluents from 500 m upstream and downstream discharge points of two WWTPs and examined for physicochemical qualities, prevalence of Vibrio pathogens and their antibiogram profiles using both cultural and molecular techniques. The findings reveal the qualities of Tsomo and Great Fish river qualities with respect to electrical conductivity (EC) (137.75 – 377.69 mg/l), total suspended solids (TSS) (52.00 – 725.19 mg/l) and temperature (12.7 – 23 oC) and the treated effluents of WW-AD and WW-CR WWTPs with respect to EC (525.73 – 1071.89 mg/l), free chlorine (0.00 mg/l – 0.68 mg/l), temperature (12.4 – 28.8 oC), TSS (14.67 – 276.44 mg/l) exceeds the permissible limits set for effluent discharged to freshwater by South Africa guidelines. Other physicochemical qualities such as turbidity (63.11 – 797.17 NTU), BOD (3.30 – 5.26 mg/l) and TDS (68.88 – 148.14 mg/l) for Tsomo and Great Fish river and turbidity (20.33 – 310 NTU), biological oxygen demand (BOD) (1.28 – 4.96 mg/l), and total dissolve solid (TDS) (262.89 – 534.89 mg/l) for WWTPs WW-AD and WW-CR did not comply with WHO and EU standards as no regulation is set for them in the South African guidelines for domestic water usage. Statistical analysis revealed that pH, electrical conductivities, dissolved oxygen and total dissolved solid were significantly different whereas temperature did not differ significantly with respect to the four seasons (P < 0.05). The Vibrio densities for Great Fish river ranged between 0 and 3.29 log10 CFU/ml with the highest obtained in the spring. The Tsomo River Vibrio densities varied between 0 to 3.56 log10 CFU/ml and the maximum densities recorded during summer. The presumptive Vibrio densities in WW-AD and WW-CR WWTPs ranged from 0 to 3.67 log10 CFU/ml and 0 to 4.42 log10 CFU/ml with autumn and spring having the highest loads respectively. Molecular identification of the presumptive Vibrio species revealed 424 positive for the Vibrio genus. Of these, 21.69 percent, 11.79 percent, 8.25 percent and 2.12 percent were confirmed as V. cholerae, V. mimicus, V. parahaemolyticus and V. fluvialis respectively. The presence of potentially Vibrio pathogens in the rivers and treated effluents suggests potential public health threat to the communities relying on receiving watersheds where the effluents are discharged. Results of antibiotic sensitivity testing revealed high sensitivities against Ofloxacin (85.54 percent), Cefuroxime (81.93 percent), and Ciprofloxacin (74.70 percent), whereas resistance against other antibiotics follow this order: Imipenem (42.17 percent), Amoxicillin-Clavulanic Acid (54.17 percent), Ampicillin (63.54 percent), Nitrofurantoin (71.79 percent) and Polymyxin B (97.44 percent). Surprisingly, the resistance of Vibrio species against the known effective Carbapenems was relatively high (Meropenem (38.54 percent) and Imipenem (58.88 percent). Multiple antibiotic resistance phenotypes (MARP) of the isolates were resistant to two or more antibiotics whereas the calculated multiple antibiotic resistance index (MARI) ranged from 0.2 to 0.7. The observed high multiple antibiotics index suggest the recovered Vibrio pathogens are of high antimicrobial usage origin. Increase in antimicrobial resistance profiles towards conventionally used antibiotics as indicated in this study calls for adequate sanitation facilities and proper surveillance programs towards monitoring of antimicrobial resistance determinants in wastewater treatment effluents and receiving watersheds. This will in turn enhance early detection of resistant strains of public health importance, and supports the prompt notification and investigation of outbreaks. It further advocates the need for constant monitoring programme by the relevant regulatory agencies to ensure total compliance of the wastewater treatment facilities to the stipulated standards.

Other physicochemical qualities such as turbidity (63.11 – 797.17 NTU), BOD (3.30 – 5.26 mg/l) and TDS (68.88 – 148.14 mg/l) for Tsomo and Great Fish river and turbidity (20.33 – 310 NTU), biological oxygen demand (BOD) (1.28 – 4.96 mg/l), and total dissolve solid (TDS) (262.89 – 534.89 mg/l) for WWTPs WW-AD and WW-CR did not comply with WHO and EU standards as no regulation is set for them in the South African guidelines for domestic water usage. Statistical analysis revealed that pH, electrical conductivities, dissolved oxygen and total dissolved solid were significantly different whereas temperature did not differ significantly with respect to the four seasons (P < 0.05). The Vibrio densities for Great Fish river ranged between 0 and 3.29 log10 CFU/ml with the highest obtained in the spring. The Tsomo River Vibrio densities varied between 0 to 3.56 log10 CFU/ml and the maximum densities recorded during summer. The presumptive Vibrio densities in WW-AD and WW-CR WWTPs ranged from 0 to 3.67 log10 CFU/ml and 0 to 4.42 log10 CFU/ml with autumn and spring having the highest loads respectively. Molecular identification of the presumptive Vibrio species revealed 424 positive for the Vibrio genus. Of these, 21.69 percent, 11.79 percent, 8.25 percent and 2.12 percent were confirmed as V. cholerae, V. mimicus, V. parahaemolyticus and V. fluvialis respectively. The presence of potentially Vibrio pathogens in the rivers and treated effluents suggests potential public health threat to the communities relying on receiving watersheds where the effluents are discharged. Results of antibiotic sensitivity testing revealed high sensitivities against Ofloxacin (85.54 percent), Cefuroxime (81.93 percent), and Ciprofloxacin (74.70 percent), whereas resistance against other antibiotics follow this order: Imipenem (42.17 percent), Amoxicillin-Clavulanic Acid (54.17 percent), Ampicillin (63.54 percent), Nitrofurantoin (71.79 percent) and Polymyxin B (97.44 percent). Surprisingly, the resistance of Vibrio species against the known effective Carbapenems was relatively high (Meropenem (38.54 percent) and Imipenem (58.88 percent). Multiple antibiotic resistance phenotypes (MARP) of the isolates were resistant to two or more antibiotics whereas the calculated multiple antibiotic resistance index (MARI) ranged from 0.2 to 0.7. The observed high multiple antibiotics index suggest the recovered Vibrio pathogens are of high antimicrobial usage origin. Increase in antimicrobial resistance profiles towards conventionally used antibiotics as indicated in this study calls for adequate sanitation facilities and proper surveillance programs towards monitoring of antimicrobial resistance determinants in wastewater treatment effluents and receiving watersheds. This will in turn enhance early detection of resistant strains of public health importance, and supports the prompt notification and investigation of outbreaks. It further advocates the need for constant monitoring programme by the relevant regulatory agencies to ensure total compliance of the wastewater treatment facilities to the stipulated standards.

- Description: Globalisation raises hopes that communities will become self reliant through development success and thus become an integrated whole (Offiong 2001). But the creation of global village leads to fragmentation of communities, a loss of norms and local values. This study focuses on communities of the Eastern Cape Province, exploring the nature of and extent to which children use alcohol as a consequence of cultural rituals. The researcher aims to develop a culturally sensitive psycho-social approach to address alcohol use among children. The purpose of the research was to investigate the extent to which certain cultural practices contribute towards alcohol use among children in the rural areas of the Eastern Cape Province. Thus exploring the nature and extent to which children use alcohol as a consequence of cultural rituals and to explore whether families and communities are aware of the impact of alcohol use by children in the community. The research was qualitative in nature and through semi-structured interview schedules the researcher was able to gain insight in the area of substance use amongst children in the rural areas of the Eastern Cape Province. Community members, learners from schools, educators and probation officers formed part of the research sample. The research findings suggest that community members are aware that the traditional rituals that are carried out in the rural areas have been contributing to the issue of children using alcohol. However, the community members feel challenged as they become conflicted by their traditional rituals and this impacts upon children using alcohol.

- Description: The aim of the current study was to assess the supply chain corruption in the three metropolitan municipalities in the Gauteng Province of South Africa. Core to the assessment was to establish the causes and ramifications of supply chain corruption as well as the nature and extent of supply chain corruption in the three metropolitan municipalities. In order to meet the objectives of the current the study, a qualitative research approach underpinned by ethics and accountability theories was used. The study employed interviews and observation as a primary source of data collection as well as document review in a form of government documents, legislation and court case decisions as secondary source of data, which were then thematically analysed. The study pointed out that while supply chain corruption certainly negatively affects the day-to-day running of public affairs, it is actually the collapse of ethical behaviour together with the failure to uphold accountability and consequence management that has created fertile ground for supply chain corruption. It further, purported that in order to combat the scourge of supply chain corruption in all its manifestations, there is a need to install a Central Supplier Database application, which has been sufficiently tested to determine its effectiveness as blacklisted companies and their directors have a way of masquerading in another form, to do business with the state. South Africa needs the embodiment of ethical behaviour from its citizenry, along with anti-corruption policy enforcement and consequence management. The Kanyane Ethics Architecture should be launched in municipalities across the board as a comprehensive and all-encompassing mix model to prevent supply chain corruption, in its various manifestations, from taking place.

- Description: The aim of this study was to develop an optimum wind power output model for concentrator augmented wind turbines (CAWTs), which can operate in low wind speed areas. This study was done using computational fluid dynamics modelling (CFD), theoretical and experimental work. Currently the wind resource is contributing 2.5percent of the global electricity supply and is anticipated to increase to by 2050. Despite this, the contribution to wind energy consumption share by South Africa is still low having just exceeded in 2015. Like many other countries, South Africa agrees that climate change is one of the biggest challenges currently being faced by mankind and acknowledges that tackling it requires collaborative effort from all. The Integrated Resource Plan (IRP 2010-2030) passed in 2010 targets 26.3percent renewable energy contribution to national energy consumption by the year 2030 with 10.3percent coming from wind energy hence contributing to abatement of climate change. 1518percent 1 000 MW Small wind turbines are known for their vital contribution to providing electricity in remote areas. Their power output is mainly influenced by the turbine rotor diameter and wind speed which depend on tower height. A cost benefit analysis conducted basing on increasing wind speed by increasing the turbine tower height revealed that for small wind turbines, the optimal height is . Concentrator Augmented Wind Turbines (CAWTs) are one of several concepts that have been suggested to increase the power output per unit rotor cross-sectional area by increasing the wind speed upstream of the turbine. Although some research effort has been put in this area, the major drawback is that the effect of concentrator geometry and environmental conditions on the aerodynamics and hence ultimate performance of CAWTs is still not clear. Also, the CAWTs systems that have been made so far, do not track the wind resulting in CAWT systems receiving wind from one direction thus limiting their performance. 25 m Wind has a very low energy density in nature implying that a bigger rotor area is required to harness kinetic energy for generation of meaningful electrical energy. This has resulted in higher costs of producing energy from wind than conventional sources of energy such as fossil fuels and hydro. To lower the cost of wind energy, researchers have come up with several initiatives to boost wind turbine power output. A brief review of various concepts that have been used in this study included: history of wind turbines, South Africa’s political will to abatement of climate change, wind resource assessment, power output augmentation, estimation of air density, historical development of CAWTs, fundamental parameters influencing the performance of CAWTs, mathematical modelling of wind turbines and dynamic similarity. Some facts were borrowed from these concepts to come up with the current study and explain the observations. With a view to assess any concept, it is necessary to study the fundamental basis from which it originates. Thus, it was vital to develop a fundamental basis of CAWT performance from which solutions to currently prevailing questions on the relationships among the governing parameters were obtained. The momentum theory of bare wind turbines, which is also found in literature was described. A similar approach was then used for developing the theory of CAWT systems. The theories of concentrator losses, density variation with weather conditions and turbulence modelling were also described. It was of utmost significance to evaluate the wind power potential of the Western part of the Eastern Cape Province to assess whether there would be a need for the concentrator augmented wind turbines (CAWTs) in the province and all other regions with similar or lower wind speeds in the country. In this study, five-year-long, hourly average wind speed series between January 2009 and December 2013 for six weather stations in the western part of the Eastern Cape (Bisho, Fort Beaufort, Graaff–Reinet, Grahamstown, Port Elizabeth and Queenstown) were statistically analysed using the Weibull distribution function. The dimensionless Weibull shape parameter varied from 1.7 to 2.2. All the values were low indicating that there is widely dispersed data. This means that the data tend to be distributed uniformly over a relatively wide range wind speed. Therefore, this has a positive implication on wind power generation in all the studied areas because if a suitable turbine is installed, it would get enough wind speed to run for the greater part of the year. The scale parameter varied between 3.5 and 6.3. The values for all the sites except Port Elizabeth were relatively low implying that the days of high wind speeds are few. Therefore, wind turbines that require high wind speeds for operation are not suitable here.

- Description: The purpose of this study was to analyse formative assessment challenges facing English Language (L2) Secondary school teachers in the Makoni District of Zimbabwe. Data were collected from 25 English Language secondary school teachers pooled from 5 secondary schools in the Makoni District. The study utilised the pragmatic paradigm which allowed the use of the mixed methods approach. The study used the survey research design. Quantitative data were collected through questionnaires while qualitative data were collected through follow-up interviews, documents and non-participant observations. Cross-tabulations were used to present data which were then reported mainly in percentages. While most of the qualitative data were used to buttress findings established through the questionnaires, the other data were categorised into themes and analysed accordingly. Major challenges that were revealed by this study were that teachers used the teacher – centred approach, feedback given to pupils was not detailed, there was less time to assess appropriately and that teachers were not motivated to assess effectively. Remedial activities were not being carried out and that teachers’ training in assessment was not thorough. Shortage of teaching and learning resources and high teacher – pupil ratios were some of the challenges that teachers faced. There was lack of coordination of agencies involved in assessment and that assessment was examinations – oriented. Assessment policy formulation did not involve teachers and that most pupils were not motivated to learn. On the basis of these findings, the study recommended the provision of adequate teaching and learning resources, provision of appropriate pre-service and in – service training programs as well as involving the teachers in the formulation of assessment policies.

- Description: The purpose of this study was to determine if monitoring and evaluation tools at a local level could help bring about sustainability of rural projects of the community based organizations thereby making the livelihoods of community members better in the Eastern Cape Province. To accomplish this objective, a case study of the training provided by Transversal Training Management Agency (TTMA) was assessed within the concept of the practice of evaluation and seeking to answer four research questions: To what extent should capacity development create sustainable managerial competencies for rural projects? Are monitoring and evaluation tools the key to sustainable projects? How will knowledge and application of M&E tools improve capacity development of CBOs? What are the policy lessons that can be derived from the application of M&E tools for the grass roots groups? The research design was in two parts namely the literature review which focuses on the roles of social change theory and program theory approaches of evaluation which is best applicable for the grassroots, then the case study of TTMA. This was a qualitative research whereby secondary data source was mainly used. The researcher was an employee of TTMA within the period of study, therefore, was able to validate information. Multiple community projects were studied using the secondary data analysis. This was necessary because of the geographic spread of the CBOs that were trained all around the Eastern Cape province and the language barrier would have pose a challenge to the researcher if all project members were to be interviewed. The main findings of the study shows that training was well conducted and project members gave positive feedback about training but what was absent in the training is a study of a monitoring and evaluation framework for the projects‘ members as one of the necessary managerial competencies in order for them to track progress and warning signals in the project cycle before it is too late. In conclusion some recommendations have been made amongst which is a practical handbook of M&E for the grassroots. This provides variety of tools that can best suit the literacy levels of project members that this study targeted. TTMA can therefore, adopt this as part of the training courses for project sustainability.

Hiv/Aids communication and youth behaviour in South Africa: a study of female high school students in the Eastern Cape Province

- Description: Human Immuno-Deficiency Virus and Acquired Immune-Deficiency Syndrome communication remains one of the most significant tools in the fight against HIV/AIDS given the absence of the cure to fight the growth and spread of the global pandemic. Through the use of information, HIV/AIDS communication seeks to empower recipients or societies with skills that will help reduce their risk of infection. South Africa has seen a high visibility of HIV/AIDS communication programmes or campaigns aimed at empowering different audiences, whilst paying particular emphasis on the most vulnerable. Young people, in particular young women, have a higher prevalence of HIV/AIDS in South Africa. This has prompted the development of many youth focused communication campaigns which have sought to address factors that increase young people`s vulnerability to HIV infection. However, despite the high visibility of HIV/AIDS communication campaigns targeting young people, high risk behaviours are still being seen among young women. Important to note are the high teenage pregnancy rates, growing abuse of substances and even the premature engagement of sexual activities among female youths. This, therefore, raises questions on the effect of HIV/AIDS communication programmes in encouraging protective behaviour against risky behavioural practices amongst young women. Using both quantitative and qualitative research approaches to this study, an investigation was conducted into whether current HIV/AIDS communication campaigns have been limited (in terms of effectiveness) when it comes to communicating with young women on issues relating to HIV/AIDS. Awareness of HIV/AIDS and HIV/AIDS communication programmes, relevance of HIV/AIDS communication programmes, the factors that influence the use and understanding of HIV/AIDS messages and the impact of HIV/AIDS communication on attitude and behaviour change amongst female youths is measured. A total of 350 questionnaire copies were self-administered to 350 participants, with a 100 percent response rate. From the 350 participants, seventy five took part in focus group discussions. Data obtained was analysed using SPSS (for descriptive statistics), and the grounded theory. The results of the study indicate that all participants were aware of HIV/AIDS with at least 60% of the participants aware of at least three HIV/AIDS communication campaigns. When measuring the relevance of HIV/AIDS communication campaigns, participants (58%) indicate that issues discussed in most HIV/AIDS communication campaigns increased the relevance of HIV/AIDS messages to young women although such relevance was, for some respondents, affected by limited access to communication campaigns. Results also show that levels of knowledge and understanding of factors that expose young women to HIV infections differed amongst participants in as much as the factors that hinder the use of advice contained in HIV/AIDS messages also differed. Sixty-nine percent of the participants have knowledge and a better understanding of factors that expose young females to HIV infections. Twenty-five percent of the participants identified peer pressure, whilst 23% identified limited access to HIV/AIDS communication campaigns and another 18% identified a disregard of HIV/AIDS messages as significant factors that limit the ability of individuals to implement advice contained in HIV/AIDS messages. The results also indicate that although HIV/AIDS communication campaigns seem to have played a role in empowering some participants, there is still a significant minority whom communication has not effectively communicated with. Based on these findings, the study suggests, amongst other things, the need to intensify current HIV/AIDS communication campaigns through the provision of consistent messages on appropriate condom use, the identification of easily accessible communication channels and the development of thought provoking and attention grabbing campaigns as well as the need to continue to directly involve young women in the processes of their own development.
