- Description: The average non-profit organisation is faced with the same cybersecurity challenges as an international multi-corporation that generates income. However, it may lack the competencies or resources to fully utilise, implement, monitor, or evaluate cybersecurity governance to a satisfactory or acceptable level. A literature review revealed limited publicly accessible documents to guide NPOs in particular in the task of cybersecurity governance. Therefore, the problem addressed by this research is the lack of a framework to guide cybersecurity governance efforts in non-profit organisations. This real-world problem was approached using the design science paradigm. It was important to identify, firstly, factors unique to the general context of non-profit organisations, including the constraints and limitations faced by non-profit organisations. Secondly, the key cyber risks for non-profit organisations and how they can materialise through the use of emails, social media, and BYODs in the NPO context, were identified. As a third step, available cybersecurity governance guidelines were analysed to determine best practices. This investigation also revealed the people, process, and technology elements as the pillars of information security. This resulted in the development of a framework (the PotLer framework) to guide cybersecurity governance efforts in non-profit organisations based on the input of the three points mentioned above. The framework was constructed around four conceptual elements, namely information security governance; people, process, and technology; governance elements; and key risks. The PotLer framework expands the high-level generic constructs beyond the conceptual space and provides implementation guidance in the form of a questionnaire to be completed by NPOs. The questionnaire was developed as an interactive spreadsheet that requires “Yes” or “No” responses from participants and generates a recommendation based on these answers. To evaluate the PotLer framework, the aforementioned questionnaire was completed by four NPOs. An additional questionnaire obtained their input on the utility and comprehensiveness of the framework.

- Description: In the past decade, increased attention has been paid to the changing role of counselling psychology in South Africa. The aim of this study is to contribute to the debates about the social responsiveness, scope and focus of the field. The following research question was formulated: What lessons about a social justice approach can a counselling psychologist learn from a youth unemployment community engagement activity? Through engagement with a group of unemployed young people about their status and exploring the role that a counselling psychologist might take, a collaborative action research approach was employed. Data were generated through collaborative action research cycles, semi-structured interviews, social media communications and the researcher’s reflective journal. Template analysis was used to make sense of the data and generate preliminary themes. Process findings illustrated the supportive and constraining role of the academic research process, the time frame and the characteristics of the target group. The content-related findings illustrated the impact of contextual and demographic factors on the participants’ unemployed status. The findings confirmed the negative effect of unemployment on psychological well-being despite support from family, friends and community members. Factors such as education and socioeconomic status influenced the job seeking behaviour of participants and although participants were aware that societal change is needed, there was evidence of internalised self-blame. Recommendations emphasise the inclusion of relevant social justice models for the context of South Africa in the training of counselling psychologists; and a pressing need to engage in micro-, meso- and macro-level advocacy to collaboratively debate the identity and scope of practice of the profession and the review of professional and ethical guidelines.

- Description: The study presents a systematic literature on contributing factors leading to prison escape. The purpose of this study is to systematically review the contributing factors that are associated with escape from correctional centre. Objectives of the study: To investigate the impact of social and cultural dynamics and triggers that motivates inmates to escape from correctional centre e.g. the internal factors and the external factors and to establish prevention strategies to deal with escapes. Method: Secondary data was employed in the study. The researcher collected the data using qualitative approach from different sources, including newspaper, prison journals, articles and the data that was originally collected for other research purposes on prison escape, both internationally and nationally. Specific data within the studies and articles is used to determine the contributing factors leading to prison escape. Data was analysed using thematic analysis. Findings: External factors such as: (family problems, missing family, the external environment and contact with the external environment, residency, loss loved ones, loss of liberty and lack of stimulation and loss of control), and internal factors such as: structural factors (e.g., crowding and size of prison, transfers, loss of security); management practices (e.g., management style, staff culture, inadequate institutional management); and environmental influences (e.g., alcohol and drug abuse, institutional crisis situations, parole problems, institutional misconduct and punishment, institutional programs, violence in prison (vulnerability to violence and gang related), limitation of goods and services, limitation of autonomy, sexual deprivation, inadequate facilities, unnatural environmental conditions are contributing factors leading to prison escapes. Conclusion: The more closely the conditions of imprisonment approximate those normally seen outside, the better the inmates can learn to survive without resorting to criminal. This allows them to also learn the ways that will help them survive outside the correctional centre and function as normal citizens. More opportunities must be created for inmates to pursue a meaningful life in prison and the existing programmes should be continuously checked if they are being practised properly. Encourage inmates to keep contact with relatives and mends so that they do not lose contact with the outside world. Correctional staff and administrators pay close attention to the policies and practices for circumstances in which violence is likely to occur, such as during inmate transport.

- Description: Abalone poaching is a major problem in South Africa. The South African abalone, Haliotis midae, rates as an extreme example of high levels of illegal harvesting. The research aimed at examining the role of the different role players in preventing poaching of the species in the East London area of the Eastern Cape Province of South Africa and determining the challenges the officers faced as there was an increase in poaching in the area. To achieve this aim, the research techniques including questionnaires, interviews and focus groups were used. Fisheries compliance and enforcement faces challenges of the illegal harvesting of abalone since 1994. In the past 18 years (1994-2012), and more specifically in the past nine years (2004-2012), poaching of abalone has increased at an alarming rate along the East London coastline. The failure of the state to issue fishing rights and conduct effective sea-based compliance, combined with the incentives to fish abalone created the conditions for rapid emergence of illegal harvesting. The uncontrolled fishing had a dramatic effect on the stock, and the average size of abalone decreased significantly. The Eastern Cape Province abalone cultivation industries were developed due to the decline in harvesting of abalone. Government departments such as the Department of Agriculture, Forestry and Fisheries; the Department of Economic Development, Environmental Affairs and Tourism; the South African Police Services together with the Eastern Cape Parks and Tourism Agency have conducted joint operations to combat the illegal harvesting of abalone. These operations have led to many arrests of abalone poachers along the East London coastline. The quantity of confiscated abalone has increased from 2007 to 2011. The positive results achieved by the departments during joint operations showcase robust efforts to eradicate the environmental transgression in the East London Coastline. Joint operations are encouraged by all the departments to save the species for future generations. Workshops involving different stakeholders had to take place and the policies in place must have a bottom-up approach where communities are involved.

- Description: Researchers hold numerous perceptions of the educational aspirations and future career choices of teenage girls. Studies argue that factors such as the curriculum, teachers' and parents' attitudes, the impact of HIV/AIDS, and teenage pregnancy, influence girls' future educational and occupational hopes and dreams either positively or negatively. Other researchers claim that learners' career choice is limited by their potential and school performance. The existing literature also suggests that girls have lower self-esteem and levels of achievement than boys. This research seeks to gain insight into high school girls' perceived academic and vocational prospects. The research was carried out in an interpretive paradigm. Six secondary school female learners from one school participated in the study. Semistructured interviews were the core method of data collection, supplemented by questionnaires and a focus group interview. As teenagers, the girls were expected to already have started to think about their future hopes and dreams. The findings revealed that all the girls seemed to experience school as a place where they could acquire knowledge about what they needed to make them autonomous and successful in adult life. For them, their parents remained their major significant others. They regarded fear of poverty as a major factor motivating them to achieve their educational and vocational aspirations. Peer pressure appeared not to be a major determinant of these girls' successes in school. The girls believed that there is a relationship between their academic performance and their future vocational choice. In addition, the girls did not see boys as a threat to their climbing the ladder of success.

- Description: The move towards greater democracy and participation in our education system is legislated quite succinctly in our South African Schools Act. The Act furthermore, and more importantly for this case study, posits that decision-making should be democratic in nature and our schools should eventually become governed in a collaborative and co-operative manner. Other policy texts such as the Labour Relations Act and the South African Constitution canonise the demand for a democratic South African society. This study investigates how democratic decision-making practices are taking place in an East London Secondary School namely Ebenezer Majombozi High. Even though distinct links exist between management and governance arms of schools, this study concentrates predominantly on decision-making within the school governing body and touches briefly on management thinking trends as a theoretical background to the kind of management at the school. What makes the school interesting as a case study is its rich history and its location in a deprived and impoverished township environment. The school was also part of the ex-Department of Education and Training, the black educational department of the past apartheid state. The kind of research undertaken was in the form of unstructured personal interviews with influential stakeholders at the school. Some of these stakeholders fonn part of the school governing body and the questions asked probed forms of governance at the school and how decision-making impacted on the overall school governance. The research findings acknowledges that decision-making does occur democratically at the school but that the practical implementation of positive consensual decisions are rarely realized. The school governing body only meets to deal with crises underpinned by a lack of learning and teaching and has not even debated the policies within the South African Schools Act. The study also argues that only by building capacity within the school and empowering the stakeholders, can constructive participation by all become a reality.

- Description: The aim of this study was to characterise and cryopreserve semen of the indigenous Namaqua Afrikaner breed, and to compare it to that of Dorper and Dohne Merino sheep, whose semen is commercially frozen on a large scale. The study was conducted between January and August 2015. September 2013-born Namaqua Afrikaner (12), Dohne Merino (12) and Dorper (9) rams were used in the study. The rams were kept under kraal conditions with adequate shade, and they received a high protein, high energy diet. Originally it was envisaged to collect semen samples using the artificial vagina (AV) method, which proved to be problematic with the Namaqua Afrikaner rams. Semen samples were subsequently collected twice a week by either AV (Dohne Merino and Dorper) or electro-ejaculation (EE; all three breeds). Macroscopic sperm traits were assessed and sperm concentration determined immediately after collection. Each semen sample was diluted with Triladyl® (1:3) and subsequently frozen in liquid nitrogen vapour in straws. Frozen straws were thawed and evaluated at 7, 30 and 90 days after cryopreservation. A droplet (0.5 ml) from each thawed sample was assessed microscopically for post-thaw motility and percentage live sperm. Nigrosin-Eosin smears were prepared of fresh, diluted and frozen-thawed semen samples for determination of percentage live sperm. Data of all the traits were analysed with the GLM and CHI-SQUARE procedures of the SAS statistical package. Breed had a significant effect on ejaculate volume of fresh semen collected either via electro-ejaculation or artificial vagina. Dorper rams (1.37 ± 0.08 ml) and Dohne Merino rams (1.20 ± 0.08 ml) produced ejaculates with higher (P <0.05) semen volume than Namaqua Afrikaner rams (1.09 ± 0.08 ml) when using the EE. With the AV method, Dohne Merino rams (1.46 ± 0.08 ml) produced a higher (P <0.05) ejaculate volume than Dorper rams (1.22 ± 0.08 ml). Motility of the frozen-thawed semen samples was lower than that of the fresh and diluted samples for all breeds and collection methods. Furthermore, motility 3 hours after thawing was also lower than motility assessed immediately after thawing for all breeds and collection methods. Motility of frozen-thawed semen collected with an AV and evaluated at 7, 30 and 90 days after freezing was significantly higher than that collected via EE. Dorper rams had the lowest sperm concentration (1.10 ± 5.29x109 sperm/ml) and the Namaqua rams the highest sperm concentration (1.22 ± 5.20x109 sperm/ml) (P ˂0.05). The AV samples had a higher (P >0.05) sperm concentration (1.20 ± 3.68x109 sperm/ml) than the EE samples (1.11 ± 3.51x109 sperm/ml). The percentage live sperm in the fresh semen samples did not differ among Namaqua Afrikaner (67.76 ± 1.94percent), Dohne Merino (68.59 ± 1.94percent) and Dorper (72.82 ± 1.98percent) rams. The percentage live sperm for all three breeds dropped considerably after freezing to 17.76 ± 2.03percent, 17.86 ± 2.03percent and 22.72 ± 2.07percent respectively. It remained constant for all the breeds from 7 until 90 days after freezing, indicating that length of storage should not have an effect on percentage live sperm for semen collected via AV or EE. Percentage live sperm of the frozen-thawed semen of the Namaqua rams was lower than that of the Dorper rams, indicating that the Namaqua semen collected via EE did not freeze as well as that of the Dorper semen. In conclusion, neither fresh nor frozen-thawed Dorper and Dohne Merino semen collected via EE did differ significantly. Furthermore, except for semen volume, Dorper and Dohne Merino semen collected via AV did not differ significantly whether evaluated as fresh or frozen-thawed semen. However, both Dorper and Dohne Merino rams produced semen with higher motility and a higher percentage live sperm post-thaw when the semen samples were collected via an AV than via EE. From these results it can therefore be postulated that if Namaqua semen were collected via AV it could have a higher post-thaw percentage live sperm than if semen was collected via EE. Advanced further studies are necessary to investigate the reason for the lower post-thaw survival rate of sperm of the Namaqua Afrikaner rams. This is necessary as semen stored in a cryobank for breeding and conservation purposes for this endangered breed has to be of high quality. Such resources as cryobanks are expensive and funds cannot be wasted on preserving inferior samples that could not fertilize an ovum when needed. The low percentage of live sperm obtained with the frozen-thawed samples in this, as well as other studies on indigenous breeds, is an indication that further research is needed into more suitable freezing protocols. It can be concluded that Namaqua Afrikaner semen cannot be frozen successfully for the purpose of storage in a cryobank, when using a freezing protocol based on Triladyl® as extender. Furthermore, any increase in post-thaw survival rate of sperm will be beneficial and it is therefore suggested that all efforts be made to solve the problem of the Namaqua Afrikaner rams that do not want to ejaculate into an artificial vagina.

- Description: The aim of this study was to characterise and cryopreserve semen of the indigenous Namaqua Afrikaner breed, and to compare it to that of Dorper and Dohne Merino sheep, whose semen is commercially frozen on a large scale. The study was conducted between January and August 2015. September 2013-born Namaqua Afrikaner (12), Dohne Merino (12) and Dorper (9) rams were used in the study. The rams were kept under kraal conditions with adequate shade, and they received a high protein, high energy diet. Originally it was envisaged to collect semen samples using the artificial vagina (AV) method, which proved to be problematic with the Namaqua Afrikaner rams. Semen samples were subsequently collected twice a week by either AV (Dohne Merino and Dorper) or electro-ejaculation (EE; all three breeds). Macroscopic sperm traits were assessed and sperm concentration determined immediately after collection. Each semen sample was diluted with Triladyl® (1:3) and subsequently frozen in liquid nitrogen vapour in straws. Frozen straws were thawed and evaluated at 7, 30 and 90 days after cryopreservation. A droplet (0.5 ml) from each thawed sample was assessed microscopically for post-thaw motility and percentage live sperm. Nigrosin-Eosin smears were prepared of fresh, diluted and frozen-thawed semen samples for determination of percentage live sperm. Data of all the traits were analysed with the GLM and CHI-SQUARE procedures of the SAS statistical package. Breed had a significant effect on ejaculate volume of fresh semen collected either via electro-ejaculation or artificial vagina. Dorper rams (1.37 ± 0.08 ml) and Dohne Merino rams (1.20 ± 0.08 ml) produced ejaculates with higher (P <0.05) semen volume than Namaqua Afrikaner rams (1.09 ± 0.08 ml) when using the EE. With the AV method, Dohne Merino rams (1.46 ± 0.08 ml) produced a higher (P <0.05) ejaculate volume than Dorper rams (1.22 ± 0.08 ml). Motility of the frozen-thawed semen samples was lower than that of the fresh and diluted samples for all breeds and collection methods. Furthermore, motility 3 hours after thawing was also lower than motility assessed immediately after thawing for all breeds and collection methods. Motility of frozen-thawed semen collected with an AV and evaluated at 7, 30 and 90 days after freezing was significantly higher than that collected via EE. Dorper rams had the lowest sperm concentration (1.10 ± 5.29x109 sperm/ml) and the Namaqua rams the highest sperm concentration (1.22 ± 5.20x109 sperm/ml) (P ˂0.05). The AV samples had a higher (P >0.05) sperm concentration (1.20 ± 3.68x109 sperm/ml) than the EE samples (1.11 ± 3.51x109 sperm/ml). The percentage live sperm in the fresh semen samples did not differ among Namaqua Afrikaner (67.76 ± 1.94percent), Dohne Merino (68.59 ± 1.94percent) and Dorper (72.82 ± 1.98percent) rams. The percentage live sperm for all three breeds dropped considerably after freezing to 17.76 ± 2.03percent, 17.86 ± 2.03percent and 22.72 ± 2.07percent respectively. It remained constant for all the breeds from 7 until 90 days after freezing, indicating that length of storage should not have an effect on percentage live sperm for semen collected via AV or EE. Percentage live sperm of the frozen-thawed semen of the Namaqua rams was lower than that of the Dorper rams, indicating that the Namaqua semen collected via EE did not freeze as well as that of the Dorper semen. In conclusion, neither fresh nor frozen-thawed Dorper and Dohne Merino semen collected via EE did differ significantly. Furthermore, except for semen volume, Dorper and Dohne Merino semen collected via AV did not differ significantly whether evaluated as fresh or frozen-thawed semen. However, both Dorper and Dohne Merino rams produced semen with higher motility and a higher percentage live sperm post-thaw when the semen samples were collected via an AV than via EE. From these results it can therefore be postulated that if Namaqua semen were collected via AV it could have a higher post-thaw percentage live sperm than if semen was collected via EE. Advanced further studies are necessary to investigate the reason for the lower post-thaw survival rate of sperm of the Namaqua Afrikaner rams. This is necessary as semen stored in a cryobank for breeding and conservation purposes for this endangered breed has to be of high quality. Such resources as cryobanks are expensive and funds cannot be wasted on preserving inferior samples that could not fertilize an ovum when needed. The low percentage of live sperm obtained with the frozen-thawed samples in this, as well as other studies on indigenous breeds, is an indication that further research is needed into more suitable freezing protocols. It can be concluded that Namaqua Afrikaner semen cannot be frozen successfully for the purpose of storage in a cryobank, when using a freezing protocol based on Triladyl® as extender. Furthermore, any increase in post-thaw survival rate of sperm will be beneficial and it is therefore suggested that all efforts be made to solve the problem of the Namaqua Afrikaner rams that do not want to ejaculate into an artificial vagina.

- Description: The aim of the study was to evaluate school children’s attitudes towards Physical Education in selected Mutare city schools. In order for the children to benefit from the Physical Education program, the study hypothesized that children must develop the right attitudes towards Physical Education. This observation has also been emphasized in other studies that children, who possess the right attitude towards Physical Education, develop positive attitudes towards physical activities. This suggestion has also been reported by Portman, (2003) and McKenzie (2003) that one of the benefits of Physical Education is sustained participation in physical activities outside the school. This study involved 400 children from Mutare Junior, Chancellor, Zamba, Dangamvura, Sakubva, Chikanga, Mutanda and Murahwa Primary Schools in Mutare city. The children’s age ranged between 12 - 14 years old. The primary data were collected from questionnaires, interviews and focus group discussions, while secondary data were based on related literature review. The results indicated that the teacher, curriculum content and delivery, the learning environment, siblings, type of school, location of residences, proximity of facilities and support from parents were some of the factors associated with children’s attitudes towards Physical Education and Physical Activity at school and home respectively. In many ways, these factors affected children’s sustainable participation in physical activities after school.

- Description: Discovery has shown that many deaths arising from cardiovascular disease often show early symptoms of high blood pressure, which makes it the leading risk factor of cardiovascular diseases. There is a distressing rate of 970 million hypertensive patients worldwide, a higher ratio of 640 million are from developing countries, if proper measures are not taken, there will be a higher growth of cardiovascular disease in adults by 2025. The focus of this study was to compare the therapeutic potentials of the anti-hypertensive therapies, drug A (amiloride + furosemide) and drug B (hydrochlorothiazide + enalapril) used in the treatment of cardiovascular disease patients for their capability to lengthen remission duration and survival time. All patients were diagnosed with a type of cardiovascular disorder, therefore patient records were followed up and blood pressure was being monitored for a period of two years. The retrospective data gotten from the public health facility was analysed using survival analysis methods. The results revealed that there was no statistical significance in the distributions of the length of remission and survival time of drug A and drug B patients. Also, in the age category, CVD patients that are 55 and above recover faster with drug A, while CVD patients below 55 shows a better survival with drug B. Then again, estimates from the gender category show a better survival in males using drug A, while the females thrive slightly better using drug B. Among all the risk factors considered in the study, only employment status showed a strong impact on survival time (remission). The findings from this study may help to formulate interventions and strategies that will increase the lifespan of cardiovascular patients and reduce early mortality due to cardiovascular diseases.

- Description: The use of herbaceous legumes such as Mucuna (Mucuna pruriens) can assist to recapitalize soil fertility depletion and improve livestock productivity in the small holder farming sector of South Africa. The objective of the study was to investigate the effect of phosphorus fertilizer application (0, 20, 40 and 60 kg P/ha) on the dry matter yield and nutritive value of Mucuna pruriens. The study was conducted at University of Fort Hare Research farm in Alice, South Africa. The research design was a randomized complete block design with three replicates per treatment. Data collection included biomass production and nutrient content of Mucuna pruriens. The forage legume was harvested at flowering stage of growth and analysed for chemical composition. The results showed that with the application of 60 kg P/ha Mucuna had the highest (P < 0.05) fresh and dry matter yield of 19.58 kg/ha and 5.41 kg/ha, respectively compared to other treatments. However, all the other treatments differed from one another. Similarly, the fresh stem and leaf fractions yield and their dry matter yields showed the same trend with application of 60 kg P/ha having the greatest yield compared to the other treatments. Nevertheless, all the treatments differed (P<0.05) from one another with P0 having the least yields. The leaf to stem ratio did not show any significant (P>0.05) difference among all the treatments ranging from 1.44 to 1.62 in fresh forage and ranging from 1.31 to 1.50 in the dry forage. In terms of dry matter content, the control treatment had the highest dry matter content of 37.78percent, however, all the other treatments did not differ significantly (P < 0.05) from each other. There was no significant effect of P application (P > 0.05) in terms of ash, EE, ADF, CP, Ca, Mg, K, Na, P, Zn, Cu, Mn and Fe of the whole plant forage among the treatments. The application of 40 kg P/ha fertilizer significantly (P < 0.05) increased the NDF (51.16percent) of the whole plant of Mucuna compared to the other treatments which did not differ (p>0.05) among themselves. Within the stem fraction there were no significant (P > 0.05) differences among the treatments for the ash, EE, ADF, NDF, and CP, hemicellulose, Ca, Mg, K, P, Zn, Cu, Mn and Fe contents. However, the application of 40 kg P/ha fertilizer significantly (P < 0.05) increased the Na (0.05percent) content of the Mucuna stem fraction. In the leaf fraction of Mucuna there was no significant (P > 0.05) differences in terms of ash, EE, ADF, NDF, CP, hemicellulose, Ca, K, P, Zn, Cu, Mn and Fe among the treatments. However, the application of 20 kg P/ha fertilizer significantly (P < 0.05) increased the Mg (0.52percent) of the Mucuna leaves compared to the other treatments. Therefore the study has shown that increase in P application (60 kg P/ha) has no major effect in the nutrient content of Mucuna. Furthermore, it is recommended that Mucuna can be grown as a protein supplement, based on the CP content values that were recorded in this study and to provide maintenance requirements for ruminants. It was therefore concluded that phosphorus fertilization particularly 60 kg P/ha is necessary and required for optimum growth of Mucuna pruriens in order to increase forage yield. Based on the nutrient content result it was concluded that there was no effect of P fertilizer application levels on the nutrient content of Mucuna pruriens in Alice.

- Description: Effects of feeding Moringa oleifera leaf meal as an additive on growth performance of chicken, physico- chemical shelf-life indicators, fatty acids profiles and lipid oxidation of broiler meat The main objective of the study was to determine the effect of M.oleifera leaf meal (MOLM) as an additive on growth performance, carcass characteristics, physico-chemical shelf-life indicators (colour, ultimate pH, driploss), fatty acids profiles and lipid oxidation of meat from broilers. A total of 432 1day old unsexed broiler chicks (Aviane 48) were randomly allocated to four dietary treatments (TRTS) in 72 cages. There were 18 cages per treatment and each cage allocated 6 chicks. Water and feed was provided at ad libitum. The feeding phases were, prestarter (0-7 Days), starter (8-18 Days), grower (19-28 Days), finisher (29-35 Days). The four TRTS contained graded levels of MOLM at 1000g/ton, 750g/ton, 500g/ton, and 0g/ton (control), respectively. The birds were slaughtered at 35 days of age. Breast muscles were sampled for meat, ultimate pH (pHu ), colour, drip loss over a 7 days shelf-life test. After each day’s test sub-samples were dipped in liquid nitrogen and kept at -180 C for thiobarbituric acid reactive substances determination. On Day1 and Day 7 extra sub-samples were also kept at -180 C for fatty acids analysis.The TRTS had no effect on average feed intake (AFI), feed conversion efficiency (FCE), and on average daily gain (ADG). Slaughter weight (SW), carcass weight (CW), dressing percentage and gizzard weight (GW) values were similar in all TRTS. Liver weight (LW), heart weight (HW), and gastro-intestinal fat (GIF) differed in all the TRTS, with treatment 2 having the highest value of HW (28.3±2.55), and LW (44.2±1.60) was the highest on treatment 4 . The pH values in all TRTS were constant from Day1 to Day5, reached peak on Day6, and then declined on Day7. Meat from broilers given treatment 1 with MOLM (1000g/ton) had the highest lightness (L*) values. The redness (a*) values were the highest in meat from treatment 2 (750g/ton MOLM). Treatments had no effect on yellowness (b*) values and on drip loss of the breasts. During storage L* values were high from Day1 to Day5 and decreased from Day6 to Day7. Drip loss increased with storage time as expected. Treatment 4 (control) had the highest proportions of poly-unsaturated fatty acids (PUFA) (30.3±1.87). Treatment 1 (1000g/ton) had the highest proportion of saturated fatty acids (SFA) (60.9±1.87). Treatment 1 (1000g/ton) had the highest proportion of SFA (60.9±4.30). Treatment 2 (750g/ton) had the highest n-6/n-3 ratio than other TRTS. Days had no effect (P>0.05) on PUFA, SFA, and n-6/n-3 ratio. Treatment 1 had a highest amount of malondialdehyde (MDA), treatment 4 had no effect (P>0.05) on MDA . Storage time had an effect (P<0.05) on MDA levels, except for on Day1 and Day7. Day2 had the highest amount of MDA (0.7±0.08). The use of MOLM as an additive in broiler diets reduced lipid oxidation in meat, and maintained the quality of the broiler meat during storage. It also did not have any adverse effects on the growth performance of broilers. Therefore, it has the potential to be used as an additive in broiler diets.

Treatment 2 (750g/ton) had the highest n-6/n-3 ratio than other TRTS. Days had no effect (P>0.05) on PUFA, SFA, and n-6/n-3 ratio. Treatment 1 had a highest amount of malondialdehyde (MDA), treatment 4 had no effect (P>0.05) on MDA . Storage time had an effect (P<0.05) on MDA levels, except for on Day1 and Day7. Day2 had the highest amount of MDA (0.7±0.08). The use of MOLM as an additive in broiler diets reduced lipid oxidation in meat, and maintained the quality of the broiler meat during storage. It also did not have any adverse effects on the growth performance of broilers. Therefore, it has the potential to be used as an additive in broiler diets.

- Description: Financial liberalization in South Africa was a process that took the form of various legal reforms very a long period of time. This study uses quarterly financial data from 1969 quarter one to 2009 quarter four to analyse this process. The data used was pertinent to the financial liberalization theorem by McKinnon (1973) and Shaw (1973). The examination of the relationships between the various macro economic variables has important implications for effective policy formulation. The empirical analysis is carried out in four phases: the preliminary analysis, the principal component analysis (PCA), the cointegration analysis and pair wise Granger causality tests. The preliminary analysis examines trends over the sample period and reports the on the correlation between the selected variables. The PCA analysis was used to create indexes for financial liberalization, taking into account the phase wise nature of legal reforms. The generated index was representative of the process of financial liberalization from 1969 to 2009. A financial development index was also created using the various traditional measures of financial development and through PCA which investigated interrelationships among the variables according to their common sources of movement. Cointegration analysis is carried out using the Johansen cointegration procedure which investigates whether there is long-run comovement between South African economic growth and the selected macroeconomic variables. Where cointegration is found, Vector Error-Correction Models (VECMs) are estimated in order to examine the short-run adjustments. For robustness, many control variables were added into the model. The results showed that there are positive long run relationships between economic growth and financial liberalization, financial development and a negative relationship with interest rates. The Granger results suggested that the MS hypothesis does not manifest accurately in the South African data. The implications of the results were that financial liberalization has had positive effects on economic growth and thus any impediments to full financial liberalization must be removed albeit with considerations towards employment and local productivity. Financial development also possessed positive long run relationships with economic growth, although results differed based on the financial development proxy used. Thus, financial development must be improved primarily through liberalizing the banking sector and spurring savings.

- Description: Gender-based Violence (GBV) has emerged as a major issue on the international human rights agenda and a major public health challenge throughout the world. A large proportion of the violence committed against women is perpetrated by their intimate partners. According to the World Health Organization’s Multi-country Study on Women’s Health and Domestic Violence, it is estimated that approximately 10% to 60% of married women have experienced physical intimate-partner violence during their lifetimes (Garcia-Moreno, Jansen, Ellsberg, Heise and Watts, 2006). Once the extent of GBV in South Africa was realised interventions were put in place to address the issue and the Domestic Violence Act No 116 of 1998 (DVA) was instituted by the South African government, aimed at protecting and combating violence against women. The notion of ending GBV was also acknowledged by the late former South African president, Nelson Mandela (Nelson Mandela’s first State of the Nation Address in Parliament in Cape Town, South Africa, 24 May 1994) said: “Freedom cannot be achieved unless the women have been emancipated from all forms of oppression." (www.ehow.com, first accessed 9 August, 2013). People Opposing Woman Abuse (POWA), a Johannesburg-based non-governmental organization (NGO), initiated interventions to address GBV. POWA offers services to women in South Africa (SA) who have experienced domestic violence, sexual harassment or rape and other forms of violence, by aiming to creating a safe society where women are powerful, self –reliant and respected. Driven by the need to create a collective space through which women could share their stories of surviving GBV, POWA established the Women’s Writing Project (WPP) in 2005. The project publishes annual anthologies with specific themes for a particular year, giving women survivors a platform and opportunity to tell their stories as an important part of the healing process. Though the first anthology was published in 2005, this thesis only provides an analysis of the POWA WWP anthologies from 2008-2013. The notion that narratives can be used as therapeutic tools had prompted the researcher to use existing narratives as a basis to investigate GBV. The study is a qualitative, interpretive study, using content analysis as a method and working within the framework of the Ecological model (1999:18) which talks about the multi-faceted nature of GBV. A total of 65 English narratives, 13 per anthology, by survivors of GBV were used and common themes that emerged were identified to obtain accounts of these selected women’s perceptions, experiences and articulations on GBV. Informed by a theoretical framework consisting of Heise, Ellsberg and Gottemoeller’s Ecological model (1999:18), the USAID GBV Life cycle model (2009:15) and the United Nations High Commission for Refugees (UNHCR) GBV health effects document (2005:23), the researcher extracted the main overarching themes which emerged from the women’s narratives. Drawing on the study’s content analysis methodology and the subsequent emerging main narrative themes, the researcher could draw certain conclusions about general similarities in the experiences and perceptions about GBV of the women who participated in POWA’s Johannesburg-based five-year Women’s Writing Project (2008-2013). The most salient of these conclusions are that the following issues are major factors contributing to GBV in the specific sample group, and by assumption also among the larger population that it represents: alcohol abuse and the absence of mother figures. Conclusions about the effects of GBV include that most women suffer from psychological health effects due to GBV experiences. Based on the selected narratives in this study the researcher could conclude that self-narrative storytelling and the recounting of traumatic experiences had therapeutic potential in the treatment and recovery of survivors of GBV. Many of the narrators said that structured self-narration and the publication of their stories had helped to construct a recovery support system not only for themselves but also for those who are possibly still suffering from the consequences of violence. In this way survivors of GBV can therapeutically construct new identities for themselves, which transcend their abuse and thereby actively participate in the construction of meaning in their lives.

- Description: In this research study, the researcher investigates obstacles faced by news journalists in investigative journalism in a democracy as experienced in Botswana. Investigative journalism and democracy have a symbiotic relationship. This relationship serves to make the public sensitive about, and aware of, injustices and undemocratic practices and it could, ultimately, contribute significantly to the process of democratization (Faure 2005: 155). Unfortunately, in their endeavor to keep up with the ethos of investigative journalism, journalists meet obstacles that range from legal to financial issues. The author investigates those factors that reporters in Botswana rate as having the greatest impact on their investigative efforts. The study also assesses the attitudes of journalists in the country towards the roles and responsibilities of the fourth estate, which supports investigative reporting. Investigative journalism is centered on disclosure, described by six elements: public interest, theme, accuracy, follow-up reports, consequences and questioning the status quo (Faure 2005:160; Marron 1995:1). The researcher interrogated the current practice of investigative journalism in newsrooms in the Botswana context, by means of a self-administered questionnaire. A cumulative sum of scores of each rank order for each obstacle was used to observe the one rated the most impeding by Botswana journalists. Elementary descriptive statistics in the form of percentages were used to assess attitudes of Botswana journalists towards investigative journalism. The same method was used to assess the proportion of investigative stories in four sampled Botswana newspapers. The contents of the respective newspapers were assessed against the five elements of investigative reporting that include: theme, public interest, questioning the status quo, accuracy, follow-up reports and consequences.

- Description: The aim of the research reported in this document was to explore the ways in which first year Journalism students at a South African University construct themselves as learners. The research adopted a case study approach of purposively selected first year journalism students. In exploring this area, focus group and individual in-depth interviewing were employed which illuminated important aspects of learner identity construction. In order to make sense of these self-constructions, the research was located in the larger debates on discourse as espoused by Michel Foucault who argues that discourse constructs subjectivities. The research demonstrated that there were various discourses at play which influenced how these learners spoke and behaved. The influence of these discourses on learners' experiences varied at different times of the year. For example, the awarding of the Duly Performed (DP) certificate for students who met the minimum attendance and work requirements of a particular course, the giving of tests, exercises and examinations were some of the technologies that 'forced' students into compliance. In terms of identity formation, the heterogeneous nature of 'being' a journalism 'student' revealed that the different discourses at play influenced learner behaviour and that their identities continued to change over the year. Doing additional subjects such as Sociology, Drama, Art History and others at the same time as Journalism and Media Studies also meant that the learners had to negotiate the differing role requirements.

- Description: The aim of the study was to develop preliminary normative indications for the Rey-Osterrieth Complex figure test (ROCF). The ROCF was administered in English on the performance of Xhosa-speaking, unskilled workers (N=40), from the Eastern Cape Province. As a mode of collecting data, the research study made use of convenience sampling which ultimately led to snowball sampling. The ROCF was administered and scored according to Rey Osterrieth’s initial standardised administration instructions (Meyers & Meyers, 1995a). For all trials of the ROCF (Copy, Immediate and Delayed Recall), a score of 0-2 points were allocated to each of the 18 structural elements of the figure. The total scores were calculated out of 36, as originally defined by Osterrieth. There was no statistically significant difference in performance for the quality of education for any of the ROCF test trials (p≥0.05 in all instances). Similarly, no significant difference is indicated for the Copy and Immediate Recall (IR) trial for sex indications, whilst the Delayed Recall (DR) trial shows statistically significant differences. Age effects appeared to have an influence on test performance on all ROCF test trials, as a significant difference was identified for all instances. Descriptively and statistically, the present local sample’s mean performance was compared to a demographically equivalent local study (de Kock’s study, which the present study is doing an extension on) and non-local normative studies. The results indicate the need for culturally-relevant South African psychological assessment measures. It also emphasises the importance of making a psychological measure more applicable and relevant to a specific context. Consideration of socio-cultural factors for norm purposes is strongly recommended by this study.
