  • 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: 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: Literature shows that there is a relationship between health expenditure and a country’s level of development. The labour productivity depends on health and the level of education of the employees. Given this background, the study’s main objective was to examine the impact of public healthcare expenditure on economic development in South Africa for the period 1996- 2016 utilising the Autoregressive Distributed lag Model. The empirical results show that there is a positive relationship between Public Health Expenditure and Human development Index. This shows that an increase in government expenditure on health increases economic development in South Africa. The results are consistent with other previous studies such as Wang (2015) and Riayati and Unaidah (2016). The study recommends that the government should increase public health expenditure. This will increase economic development. The government can do this by building hospitals and rolling out more funds to improve the healthcare in South Africa. The study also recommends that the government should reduce unemployment. Unemployment has been seen to have an undesirable impact on economic development

  • Description: There has been increasing recognition in the past few decades that rural households in developing countries are not limited to the agricultural sector, but also depend on other, nonagricultural activities. Rural households are understood to pursue multiple livelihood strategies which involve juggling different economic pursuits as a means of reducing risk and maintaining options. In South Africa, the importance of multiple livelihood strategies is widely appreciated, on the other hand there is a common perception in policy circles that agricultural development can become an important route out of poverty, for instance as part-time small-scale farmers become larger and more commercialised. The purpose of this dissertation is to attempt to better understand the relationship between households’ participation in agriculture and nonagricultural activities. The point of departure is the observation that there is a great deal of flux into and out of agriculture in a way that is difficult to understand in terms of prevailing theories and frameworks. The study makes use of four waves of data from the National Income Dynamics Study (NIDS), and employs a variety of analytical approaches, including transition matrices, multinomial logistic regression, and panel data econometric models. The findings are mixed. In the one hand, there is evidence that households enter agriculture as other income sources become available, and leave agriculture again when those sources dry up. On the other hand, there is also evidence that participation in agriculture compensates for the absence or loss of other income sources, in which case agriculture can be thought of as a ‘residual’ sector that is activated when other options fail.

  • 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 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: 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 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.

  • Description: The aim of the study was to investigate the role of the Child Support Grant (CSG) in enhancing the quality of life of beneficiaries in the Dimbaza Community, Buffalo city Municipality. The study utilised the quantitative research method through questionnaires to collect data from 150 beneficiaries of Child Support Grant (CSG), using the non-probability sampling method. The findings of the study highlight the fact that indeed, the beneficiaries of the child support grant are truly dependent on the Child Support Grant (CSG) income, and their livelihood depends on the grant and how they use it. Another important finding of the study is that most beneficiaries (CSG) are not fully satisfied with how the Child Support Grant fulfils the gap in terms of their needs e.g. in healthcare and schooling, amongst others. The study recommends that the government should focus more on the issue of healthcare of beneficiaries through access to private doctors whenever there is an emergency - in order to address the issue the of inaccessible doctors in public hospitals.

  • 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: Expansion of woody vegetation results in the transformation of a grass-dominated ecosystem to a tree-dominated ecosystem causing land degradation in most semi-arid areas. The imbalance in the natural ecosystem between herbaceous plants and woody vegetation poses a threat to the natural environment. Such changes alter the flow, availability and quality of nutrient resources in the biogeochemical cycle. Most of the dominating woody plants are often unpalatable to domestic livestock. Therefore, the objective is to assess the spatial extent of woody vegetation over time. Knowledge of the spatial and temporal characteristics of woody vegetation dynamics will enable the development of management plans. These characteristics can be derived using remote sensing techniques which have become efficient in such studies. This study aimed to characterize woody vegetation dynamics along the route between Alice and King Williams’s town in Eastern Cape Province South Africa using Landsat data. This aim was achieved by focussing on three specific objectives. The first objective was to compare the performance of multispectral data and Normalized Difference Vegetation Index (NDVI) data of Landsat imagery in mapping woody vegetation cover. The second objective was to investigate the effect of the spatial resolution of remotely-sensed data on discrimination of woody vegetation from other land cover types. The third objective characterised woody vegetation dynamics between 1986 and 2013/2014 using the results from the first objective. The study used Landsat imagery acquired in November or February of 1986, 1994/1995, 2002/2003 and 2013/2014. Due to lack of data which covered the study area two separate dates (November and February) where used for the study resulting in naming the study area western and eastern parts. Unsupervised classification was performed on the multispectral, NDVI and pan-sharpened images to generate four generic land cover classes, namely water, bare land, grassland and woodland. Accuracy assessments of the classified images was done using error matrix. The results showed that the classification based on NDVI images yielded a better overall accuracy than the classification based on multispectral images for the western (83 percent and 75 percent, respectively) and eastern (82 percent and 76 percent, respectively) parts of the study area. Similarly, pan-sharpening resulted in better overall classification accuracy than multispectral, but comparable to the classification of the NDVI images for both the western (82 percent) and eastern (83 percent) parts of the study area. Remote sensing is an effective tool in assessing changes in the physical environment. Landsat imagery is suitable in assessing land cover dynamics given the long-term and free availability of the image. In addition, the large spatial coverage it provides, enables Landsat data to be used on studies that have wide spatial coverage. Classification for the purpose of time-series analysis was then performed on the NDVI images of each date (1986, 1994/1995, 2002/2003 and 2013/2014). Both woody vegetation and grassland experienced changes from 1986 to 2013/2014 with grassland occupying (75 percent) compared to woodland (17 percent) in 1986. In the year 2013/14 grassland occupied 32 percent and woodland occupied 51 percent of the study area. The increase in woody vegetation in the study area can be attributed to livestock rearing and migration of people from the rural to urban areas post-Apartheid. The study output will aid in the development of a database on land cover distribution of the area between King William’s town and Alice town, providing useful information to decision-making and further studies on woody vegetation.

  • Description: The object of this thesis is to provide guidelines relating to the tax benefits that are available to investors in immovable property in South Africa. This was done by analysing the various sections of the Income Tax Act, as well as case law and South African Revenue Service guidelines that interpret these sections, which provide for expenditure which may be deducted by taxpayers from their income when conducting the trade of letting immovable property in order to reduce their overall tax liability. The thesis also includes a chapter dealing with the four different types of vehicles that taxpayers may use when investing in property. It was found that there are significant tax benefits available to investors in immovable property through the general deductions provided in terms of section 11(a) of the Act, as well as the specific deductions that the legislature has promulgated for investors in immovable property. It was also found that each of the four vehicles has its own advantages and that a taxpayer’s personal circumstances will dictate which of the vehicles will best suit his or her needs.

  • Description: This research examined the concept of base erosion and profit shifting in the context of tax schemes employed by multinational corporations. The objective of this thesis was to identify weaknesses within South Africa’s income tax legislation, based on these schemes, and further to propose recommendations to counter the occurrence of base erosion and profit shifting by multinational companies. The research also comprised of a limited review of current global and South African initiatives to address the problem of base erosion and profit shifting. It was concluded that there are a number of weaknesses in the definitions and provisions of the South African income tax legislation that need to be addressed in order to reduce base erosion and profit shifting. Brief recommendations were proposed in relation to each of the weaknesses, in order to address them.

  • 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.

Perceptions of being a learner: an investigation into how first year Journalism students at a South African university construct themselves as learners

  • 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: Marine and coastal ecosystems face widespread degradation largely because market failure hides the economic value of the goods and services provided by them. Marine protected areas (MPAs) can serve as a structure that ensures the continuing function of marine and coastal ecosystem goods and services. Yet, to be effective and sustainable, MPAs must be able to prove their economic worth and generate revenue. User-fees are a common system used to partially finance multi-use MPAs. This study applies contingent valuation as a method of economic valuation within an MPA in southern Mozambique. The objectives of this study are to determine the willingness to pay of combined user groups and of individual user groups for use of the Ponta do Ouro Partial Marine Reserve and to investigate the potential for the reserve to increase revenues for conservation through the implementation of a user-fee for marine based activities. The payment card contingent valuation method was employed to determine willingness to pay of dolphin swim tourists, scuba divers and fishermen. Data was collected by face-to-face interviews of 120 respondents within two popular tourist locations in the PPMR. Results show that visitors within the PPMR are mainly South Africans, loyal to the area. Probit and OLS regressions were used to determine the effects of various independent variables on willingness to pay. Results from the Probit model indicate that African residency, activity and environmental awareness were significant factors that influenced visitors being WTP more than R20 per person per day as a user fee within the PPMR. The OLS model examined independent variables that influenced visitors being willing to pay as well as the impact of the variables on the amount visitors were willing to pay. The OLS model found income, African residency and environmental awareness to be significant factors influencing visitors being willing to pay. The mean WTP was R43.75 per person per day. Using data supplied by the PPMR, conservative estimated annual revenues based on the implementation of this fee amount would range between R1.46m – R 3.3m.

  • 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.
