  • Description: Previous studies conducted on wool production in the communal areas of the Eastern Cape have concluded future research should focus on whether the observed differences in average wool price received between shearing sheds are due to differences in clip preparation (i.e. classing) or differences in the quality of the wool being produced (i.e. genetics).The objective of this study was to establish whether there are indeed geographical differences in the average wool price received by communal wool producers in the Eastern Cape and, if so, whether this difference in earnings is attributable to differences in the quality of wool produced and/or clip preparation. The current research explored eight years of wool production records of communal wool farmers (2009/10 to 2016/17) obtained from BKB, the largest wool broker in South Africa. Statistical analyses included descriptive statistics, analysis of variance, parametric tests (i.e. t-test) and multiple regression analysis. The conclusions drawn from this study are: that there are indeed statistically significant differences in the average wool price received between the different geographic areas of the Eastern Cape communal regions, and that the primary determining factor is wool quality, while clip preparation also plays an important but secondary role. The study identified specific geographic areas where developmental interventions are most critical, with specific emphasis on improving the genetic composition of the wool sheep flocks. Specific strategies are recommended, namely:Removing inferior-quality rams and replacing them with superior-quality rams to prevent any inferior nondescript rams from breeding and producing progeny; Replacing the inferior-quality nondescript ewes in specific areas with superior-quality ewes, and Improving the survival rate of lambs and thereby contributing towards expediting the rate of genetic improvement of the communal wool sheep flocks.

  • Description: The unique historical stressors linked to South Africa’s apartheid legacy, continues to manifest in the form of economic exclusion, social exclusion, inequality and poverty, with parents being subjugated to service users and extenders rather than included as service advocates, particularly in the child justice system. Furthermore, policies and practices do not include, engage and support parents on an intra and interpersonal level. Parents of children in conflict with the law, experience their children’s charge or arrest as well as their subsequent journey through the child justice system as a crisis resulting in their need for emotional, informational, practical and professional support during the child justice process. The similarities and differences between the contexts of child protection and child justice in supporting parents illuminates the existing gaps in child justice legislation, policy and practice resulting in a lack of support for parents during the child justice process. In the Children’s Act 38 of 2005, it is recognised that parents have a legal responsibility towards their children and that in fulfilling this responsibility parents can access support services to assist them when they face challenges in fulfilling this responsibility. In contrast, despite 80 percent of children in conflict with the law being released into parental care and parents expressing the need for support in fulfilling their parental responsibility, in this regard the Child Justice Act 75 of 2008 fails to make provision for parents to access support services. The child justice system’s narrow focus on parents as service extenders contributes to parents’ being excluded from targeted support services resulting in parents’ support needs not being addressed. The lack of programmes and services aimed at supporting parents highlight the need for coordinated services that address the multiple stressors parents are exposed to. To this end, this study was aimed at coconstructing a practice model for supporting parents of children in conflict with the law. The theoretical lenses employed in the current study namely; the Ecological systems model and the Buffering effect model describes the various systems parents need support from and the type of support they need from their family, community and professionals. Guided by a qualitative approach, the present study integrated applied research, in particular intervention design and development with participatory action research as it allowed systematic collaboration during the research process to ensure rigour. This study involved participants from two research sites namely, the Nerina One- Stop Child Justice Centre in Port Elizabeth and the Reception, Assessment and Referral office at the Uitenhage magistrates’ court. Employing a non-probability purposive sampling method, this study facilitated the participation of parents of children in conflict with the law and child justice officials who met the inclusion criteria, in the co-design and development of a practice model for supporting parents of children in conflict with the law. Participants assumed an expert and collaborative role, which enabled the co-construction of knowledge, meaning and innovation of the practice model. Qualitative data collection methods namely, twelve focus groups and thirty two participant observations, were used to explore, co-construct, describe and design a practice model for supporting parents of children in conflict with the law during the child justice process. Thematic analyses was employed to condense the data, search for codes, categories, themes, relationships and patterns in the data. Due to the research approach and design, data analysis was ongoing and informed design and development of the practice model. Based on the thematic analysis and synthesis both descriptive and analytic themes emerged. To ensure trustworthiness, this study employed various strategies to strengthen commitment, rigour, transparency and coherence. In addition, the participative research process, the inclusion of multiple forms of qualitative inquiry and the significance of the study contributed to the validity and quality of the study. Ethical considerations applicable to the study included participants’ voluntary participation, their informed consent and ensuring participants’ privacy or maintaining confidentially. Various strategies were employed to prevent or minimise risk to participants. The findings showed that formal sources of support, in particular, offer opportunities for parents to access individual and family counselling, parenting advice, and peer support. The study also highlighted the importance of recognising parents as a subsystem in the child justice system offers potential opportunities for inclusion of parents as co-facilitators of parenting programmes or support groups, as peer supporters during the child justice process. Parents’ inclusion as a partner in the child justice system is highlighted as an opportunity for parents to be able to vi participate in child justice fora, oversight committees and accreditation committees to influence policy, services and budget allocations for services to support parents of children in conflict with the law. This study’s contribution to the existing body of knowledge is an integrated, multidisciplinary, multi-phase co-constructed practice model that would enable inclusion of, and support for, parents of children in conflict with the law prior to, during and after the child justice. The co-constructed practice model (a) involves a continuum of parent-centred support for and inclusion of parents prior to, during and after the child justice process; (b) advances an inclusive and collaborative child justice system that views parents as important stakeholders in determining the type of services they need and being involved in developing practice; and (c) promotes parents as equal partners in decision making and policy making to influence legislation, policy and practice in the child justice system.

  • Description: Mobile phones have become an integral part of standard of living. Users and customers expect sensible and very useful applications in less time. In this competitive market, it is an enormous challenge to develop high performance mobile applications that might meet the expectations of end users. Despite the fact that development of new applications for each mobile operating system in short time is fairly an issue, mobile operating systems vendors are giving their best available resources for creating applications in additional convenient ways. These days, there is a common tendency to look for less complex and quicker solutions that could be used in the process of software development. Developers of a new mobile application have to undertake variety of selections and decisions, including the target platform as well as the development technology to utilize. Mobile application development frameworks contribute in solving this problem. Several frameworks have emerged, which we classify and evaluate their appropriateness. In order to compare existing development frameworks solutions in this research, we compiled a set of criteria to assess mobile application development approaches. In view on these criteria, we evaluated five frameworks that is, PhoneGap, Xamarin, App Inventor, Sencha Touch and DragonRad. For proof of concepts, the chosen framework from the five evaluated mobile development frameworks was used to develop application for water usage management. The research will equip mobile application developers to gain more insight into mobile development frameworks available, therefore helping them to choose the most appropriate framework for their project.

A comparative study of artificial neural networks and physics models as simulators in evolutionary robotics

  • Description: The Evolutionary Robotics (ER) process is a technique that applies evolutionary optimization algorithms to the task of automatically developing, or evolving, robotic control programs. These control programs, or simply controllers, are evolved in order to allow a robot to perform a required task. During the ER process, use is often made of robotic simulators to evaluate the performance of candidate controllers that are produced in the course of the controller evolution process. Such simulators accelerate and otherwise simplify the controller evolution process, as opposed to the more arduous process of evaluating controllers in the real world without use of simulation. To date, the vast majority of simulators that have been applied in ER are physics- based models which are constructed by taking into account the underlying physics governing the operation of the robotic system in question. An alternative approach to simulator implementation in ER is the usage of Artificial Neural Networks (ANNs) as simulators in the ER process. Such simulators are referred to as Simulator Neural Networks (SNNs). Previous studies have indicated that SNNs can successfully be used as an alter- native to physics-based simulators in the ER process on various robotic platforms. At the commencement of the current study it was not, however, known how this relatively new method of simulation would compare to traditional physics-based simulation approaches in ER. The study presented in this thesis thus endeavoured to quantitatively compare SNNs and physics-based models as simulators in the ER process. In order to con- duct this comparative study, both SNNs and physics simulators were constructed for the modelling of three different robotic platforms: a differentially-steered robot, a wheeled inverted pendulum robot and a hexapod robot. Each of these two types of simulation was then used in simulation-based evolution processes to evolve con- trollers for each robotic platform. During these controller evolution processes, the SNNs and physics models were compared in terms of their accuracy in making pre- dictions of robotic behaviour, their computational efficiency in arriving at these predictions, the human effort required to construct each simulator and, most im- portantly, the real-world performance of controllers evolved by making use of each simulator. The results obtained in this study illustrated experimentally that SNNs were, in the majority of cases, able to make more accurate predictions than the physics- based models and these SNNs were arguably simpler to construct than the physics simulators. Additionally, SNNs were also shown to be a computationally efficient alternative to physics-based simulators in ER and, again in the majority of cases, these SNNs were able to produce controllers which outperformed those evolved in the physics-based simulators, when these controllers were uploaded to the real-world robots. The results of this thesis thus suggest that SNNs are a viable alternative to more commonly-used physics simulators in ER and further investigation of the potential of this simulation technique appears warranted.

  • Description: There has been a significant increase in the prevalence of Ransomware attacks in the preceding four years to date. This indicates that the battle has not yet been won defending against this class of malware. This research proposes that by identifying the similarities within the operational framework of Ransomware strains, a better overall understanding of their operation and function can be achieved. This, in turn, will aid in a quicker response to future attacks. With the average Ransomware attack taking two hours to be identified, it shows that there is not yet a clear understanding as to why these attacks are so successful. Research into Ransomware is limited by what is currently known on the topic. Due to the limitations of the research the decision was taken to only examined three samples of Ransomware from different families. This was decided due to the complexities and comprehensive nature of the research. The in depth nature of the research and the time constraints associated with it did not allow for proof of concept of this framework to be tested on more than three families, but the exploratory work was promising and should be further explored in future research. The aim of the research is to follow the Hybrid-Malware analysis framework which consists of both static and the dynamic analysis phases, in addition to the digital forensic examination of the infected system. This allows for signature-based findings, along with behavioural and forensic findings all in one. This information allows for a better understanding of how this malware is designed and how it infects and remains persistent on a system. The operating system which has been chosen is the Microsoft Window 7 operating system which is still utilised by a significant proportion of Windows users especially in the corporate environment. The experiment process was designed to enable the researcher the ability to collect information regarding the Ransomware and every aspect of its behaviour and communication on a target system. The results can be compared across the three strains to identify the commonalities. The initial hypothesis was that Ransomware variants are all much like an instant cake box consists of specific building blocks which remain the same with the flavouring of the cake mix being the unique feature.

  • Description: Following the establishment of graphene quantum dots as potential phthalocyanine supports in photoactive membrane preparation for phthalocyanines lacking linkage functional groups, the practical efficiency of p-p stacking versus covalent linkage was investigated. Synthesized materials were characterized using FT-IR, Raman, powder X-ray diffraction, and UVeVis spectroscopies and also by transmission electron and scanning electron microscopies. Phthalocyanine loadings onto graphene quantum dots of 0.40 mg/mg and 0.14 mg/mg (Pc mass/conjugate mass) for the p-p stacked and covalent linked conjugates respectively were observed. Covalent linkage to graphene quantum dots proved to be functionally superior to p-p linkage, where singlet oxygen quantum yield value of the phthalocyanine in the membrane for the covalent linked conjugate was approximately twice that of the p-p stacked membrane.

  • Description: Brassica spp. are cultivated all over the world, commercial species include: cabbage, broccoli, kale, kohlrabi and turnip. In this study the focus was on broccoli (Brassica oleracea) production in the Western Cape province of South Africa and its economically important pests and diseases: sugar beet cyst nematode (Heterodera schachtii), diamondback moth (Plutella xylostella), white blister (Albugo candida) and clubroot (Plasmodiophora brassicae), and the different methods to control these pests and diseases. The control methods focused on in this study included a commercial chemical control programme, a biological control programme and a holistic approach. Other factors were bio-fumigation and chemical fumigation and different crop rotation practices including rotation crops versus no rotation crops. The experimental design was a strip split plot design, with different pest and disease management strategies as the main plot treatment and fumigation and rotation treatment combinations arranged in strips across the main plot treatments. The main plot design was a randomized complete block with four programmes (Control, Holistic, Chemical and Biological) replicated four times and laid out in a Randomised Complete Block Design (RCBD). The treatment design of the strip plot factors was a 2x2 factorial with two fumigations (fumigated chemically and fumigated biologically) and two rotations (crop rotated and monoculture) randomly allocated across main plot treatments. Each experimental unit consisted of 40 plants. Plants were evaluated weekly for the incidence of white blister and diamondback moth. Incidences of clubroot and white blister infection of heads of broccoli were recorded 78 days after planting. Baseline soil samples were analysed to establish the soil chemical properties. Post-trial soil samples were also analysed to investigate the effect of the different practices and programmes on the soil chemical properties. Nematodes were extracted pre-trial and post-trial, and the effect of fumigation and crop rotation on plant parasitic nematodes and the nematode population diversity investigated. In the post-trial soil chemical analysis, a significantly higher concentration of Na was recorded for the biological programme when crop rotation was included compared to the no rotation treatment. The concentration of K was also significantly higher in the no rotation compared to the rotation treatment. The nematode results showed very high numbers of bacterial feeders in all the samples. Overall nematode diversity was lacking and showed very few fungal feeders, omnivores and predators. The nematode indices for all of the samples showed that nematodes were highly enriched and unstructured. Of the plant parasitic nematodes, only Heterodera spp. were obtained in the pre-trial analysis, and incidences of these nematodes were lower at the end of the trial. Low numbers of other plant parasitic nematodes viz. Pratylenchus, Paratrichodorus and Tylenchorhynchus were reported for the post-trial analysis of the soil. Because of the low numbers of plant parasitic nematodes, it was not possible to analyse the data statistically. With regard to diamondback moth and the fungal diseases, crop rotation and fumigation did not significantly affect the incidence of white blister and diamondback moth. A significant “days after planting by control programme” interaction was reported for the incidence of white blister on foliage and the incidence of diamondback moth. All three control programmes significantly reduced the incidence of diamondback moth with the chemical programme being significantly more effective than the other two programmes. All three programmes also significantly reduced the incidence of white blister on foliage and the holistic and biological programmes significantly reduced the incidence of white blister on broccoli heads with the holistic programme being significantly more effective than the biological programme. There was no clubroot infection in the trial for any of the treatments. Results of this study showed that it is possible to manage diseases and pests of broccoli using a holistic approach. However, long term trials are needed to confirm the results obtained in this study.

  • Description: The increase in global rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) has had far reaching effects on healthcare services around the world. According to the 2017 statistics released by UNAIDS, South Africa has the largest HIV epidemic in the world. The South African Department of Health provides an HIV counselling and testing (HCT) service to patients in order that they may know their HIV status and endeavours to educate patients so that they may adapt their behaviours and lifestyles. The goal of this study is to develop a support programme for nurses to assist them in coping emotionally with their day-to-day activities when providing HCT services to patients attending primary healthcare clinics. The paradigm used as a lens to view the phenomenon is Kinlaw’s cyclical growth of empowerment theory. The researcher used a qualitative,explorative, descriptive and contextual design. The study involves three phases: (a) empirical research that explores nurses’ experiences of performing HCT in primary healthcare rural clinics, (b) the development of a conceptual framework for a support programme using the survey list of Dickoff et al. (1968:427). (c) the formalisation of the Comprehensive Support Programme to help nurses to cope emotionally with working with HCT on a long-term basis. Chinn and Kramer (2005118) were used to evaluate the programme. . The empirical findings revealed registered nurses experienced HCT both positively and negatively. They felt overwhelmed by the expectation that all patients attending primary healthcare clinics should be offered HCT routinely and the time constraints involved. They described how the emotional trauma attached to HCT affected their work patterns, leading to low productivity, and affected them outside work, leading to stress and sleep disturbances. They feltl disturbed that even when informed, people choose not to adopt safer sex practices and that how patients responded to a positive diagnosis cannot be predicted. Participants showed signs of stress, frustration, despair and sadness because most tested clients show positive test results and the number of clients testing positive is increasing. While participants felt helpless to improve the situation, at the same time, HCT was experienced as rewarding because it enabled diagnosis of medical conditions of which people weree not aware. The goal of the study was achieved with the development and formalisation of an extensive, relevant and applicable Comprehensive Support Programme for implementation for registered nurses to enable them cope emotionally when conducting HCT based on the empirical findings.

  • Description: Corporate Social Responsibility (CSR) requires companies to fulfil certain responsibilities in society that are outside of the core operational activities of the company. The socio-economic dynamics of the region or country that the company operates from, as well as the pressures those stakeholders tend to apply, have a bearing on the direction that the CSR development takes. Mirvis and Googins (2006) described the CSR developmental path followed by international companies. Before that Carroll (1991) had suggested a developmental pyramid that suggested that philanthropy represented the highest level of CSR development. This pyramid was later revised by Visser (2005) in order to suit the African environment. In South Africa CSR development is mainly driven by legislation through the BEE Act of 2003. This has resulted in the birth of industry charters that guide the development of CSR in different industries. To fulfil the requirements of the charter and score vital B-BBEE points, companies have to engage with both internal and external stakeholders, holistically. One such industry is the telecommunications industry, which formed the basis for this research, with special emphasis on the mobile telecommunications industry. The research set out to explore how the industry charter and company practices compared with the existing literature on CSR. The aim of this research was therefore to analyse the existing CSR practices in the mobile telecommunication industry in South Africa, where the B-BBEE Act plays a pivotal role in influencing practice. Using publically available documents, this research conducted an analysis of the B-BBEE components in the telecommunications charter as the catalyst to development of CSR in the South African mobile telecommunications industry, with the three dominant companies, - MTN, Vodacom and Cell C – being utilised as case studies. Key research findings were that transformation is still low in terms of equitable gender and racial representation at the top management level. The industry charter attempts to address these and other social challenges and economic problems. However, it does not address ecological issues that may emanate from the industry operations. Therefore, a CSR assessment framework that addresses all stakeholders for sustainable economic development is proposed.

  • Description: This study forms part of a larger project investigating attitudes towards intimate partner violence, dating violence and other forms of gender-based violence with the Rhodes University context. The primary purpose was to establish a baseline descriptive understanding of participants‟ attitudes towards and perceptions of gender-based violence. With the aim to generate results that would somehow inform the larger project, the current study sought to investigate whether a relationship exists between gender-role ideology and attitudes towards gender-based violence amongst a university population which was inclusive of registered students and employees of the university (n = 308). Four samples were categorised: student sample, academic staff sample, administrative support staff sample and operational support staff sample. A once-off, cross sectional survey design was used to obtain the data. The results of the study revealed that the participants in the study uphold largely non-traditional gender-role ideologies, are generally intolerant of dating violence and are rejecting of rape myths. As predicted in the literature, the study revealed that demographics such as gender, religion, age, level of education, number of years spent in the institution, race, and student accommodation have an impact on the relationship between adherence to traditional gender-role ideology and tolerance towards dating violence, as well as on the relationship between adherence to traditional gender-role ideology and rape myth acceptance and the relationship between rape myth acceptance and tolerance towards dating violence. The study contributes to the growing body of knowledge on gender-based violence in institutions of higher learning and could help improve sexual violence prevention programmes in such contexts.

  • Description: The sugar cane industry has for many years been a lucrative business with a booming global market. In Zimbabwe, the sugar cane industry is no exception, as it has been regarded as one of the most efficient in the region and even in the world. The sugar cane farms and mills in Zimbabwe are located in Triangle and Chiredzi, in the south-eastern part of the country and they are under the ownership of Tongaat Hullet and the Zimbabwean A2 farmers. The focus of this is on the A2 fast track farms in Hippo Valley, which are now owned by black farmers but as out-growers for Tongaat Hullet. The crucial question addressed in the thesis is whether the A2 sugar cane farmers and their workers, located at the production end of the sugar cane global value chain, are benefitting from their involvement in this value chain. A number of scholars argue that global value chains lead to economic and social upgrading at the production end of the chain, based on thoughts contained in modernisation and trickledown theory. There is an assumption, then, that integration into the global economy leads to economic upgrading which translates into social upgrading. In drawing upon critical global value theorists, bolstered by the Marxist perspective, considers the importance of a more critical view of global value chains in relation to the sugar cane industry in Zimbabwe, with the particular focus on A2 farms. Thus, the main objective of the thesis is to consider the lives and livelihoods of A2 sugar cane farmers and sugar cane workers through a case study, in the context of global value chains and arguments around economic and social upgrading. This is pursued through a case study of six A2 farms, which involved interviewing farmers, supervisors, and both permanent and temporary workers. The thesis concludes that there is no significant evidence of social upgrading amongst the labour force, and that the A2 farmers are in constant tension with Tongaat Hullet in seeking to engage in economic upgrading of their status as commercial farmers.

  • Description: For a number of decades now, development non-governmental organisations (DNGOs) have been central to the world-wide development system which involves funding from international donors. Overall, DNGOs rely quite fundamentally on their donors for organisational sustainability, such that upward accountability to donors is inevitable. At the same time, as development agents, DNGOs are often celebrated for the deep participatory methodologies used when engaging with the beneficiaries of their programmes, leading to significant downward accountability – as least potentially. Often, for DNGOs, an awkward tension between upward and downward accountability exists. This thesis considers this tension by examining a DNGO in South Africa, namely, the East Cape Agricultural Research Project (ECARP), which focuses on questions around land redistribution. ECARP works with farm labourers and dwellers on commercial farms and small-scale farmers on redistributed farms. In the context of a broader understanding of ECARP’s mission, capacities and programmes, the thesis looks specifically at ECARP’s food security and sovereignty programme amongst small-scale farmers on redistributed farms. By drawing upon Interface theory, the thesis discusses in detail the diverse manner in which ECARP uses participatory methodologies in this particular programme. The thesis concludes that there is a reasonable degree of downward accountability in this programme, but that this does not distract from the fact that ECARP remains within the tension-riddled space marked by dual demands for accountability.

  • Description: Learning is a process that involves building on prior knowledge, enriching and exchanging existing understanding where learners’ knowledge base is scaffolded in the construction of knowledge. Research on the teaching and learning of geometry in mathematics suggests that physical manipulation experiences, especially of shapes, is an important process in learning at all ages. The focus of the study was the migration of Grade 8 learners from one Van Hiele level to the next as a result of teachers incorporating visualisation processes and Van Hiele phases of instructions in their teaching. The study underpinned by the social constructivist’s theory, therefore aimed at teachers developing visual materials and using Van Hiele’s phases of instruction to teach two dimensional figures in Geometry. The study was carried out in Namibia, Zambezi region in Bukalo circuit. It involved four schools, with 93 learners and three teacher participants. The research is an interpretive case study of a planned intervention programme, which took a four weeks to complete. Participating learners wrote a Van Hiele Geometric test prior and post the intervention programme to determine their geometric level of thought. Participating teachers all received training on visualisation in mathematics and the Van Hiele theory before the intervention. During the intervention, teacher planned and each taught three lessons on two-dimensional figures. Qualitative data was collected from classroom observation, stimulus recall interviews and focus group interviews. Quantitative data came from the pre and post-test of learners. This study found that on average, Grade 8 learners who participated in the study were operating at levels lower than expected of pupils at their stage of schooling. This study also found that, visualisation processes and the Van Hiele phases are effective when used in geometry lessons to migrate learners from lower Van Hiele levels to higher. For teachers in the same circuit, partnership and planning of difficult topics on an agreed regular basis is recommended. When planning lessons teachers are encouraged to take advantage of the Van Hiele phases of instructions. This study thus recommends the incorporation of visualisation strategies of teaching geometry in particular at primary and lower secondary levels. Mathematics teachers are further encouraged to design visual materials such as Geoboards to use for every topic in geometry. Such visual materials should be carefully developed and evaluated to ensure that their use in the classroom is effectively linked to concepts under discussion in a given lesson.

  • Description: Cryptocurrencies are decentralised virtual currencies, using blockchain technology to process peer-to-peer electronic payments. In 2009, the first successful cryptocurrency, Bitcoin, was established. As a result of the Internet, cryptocurrencies had soon made their way into South Africa. As such, cryptocurrencies are currently not included under the definition of a legal tender and therefore remain unregulated by the legal framework. This issue is examined within this research project. The objectives were to understand the concepts of cryptocurrency, the relevance in the financial sector, the associated risks and to establish whether regulatory interference is necessary for the operation of cryptocurrency. The legal and regulatory framework of cryptocurrencies within Canada, the United States of America and the European Union were compared to that of South Africa. The research explained that cryptocurrencies are decentralised convertible currencies which are secured by cryptography. It highlighted the risks associated with cryptocurrencies, some of which are detrimental due to the wide use of cryptocurrencies. One of the risks included using cryptocurrencies to launder money. In order to mitigate these risks, jurisdictions such as Canada, the United States of America and the European Union have begun to regulate cryptocurrencies by establishing a legal framework for its operation. However, no such legal framework existed in South Africa for the regulation of cryptocurrencies. As a result, the South African Reserve Bank and National Treasury released position papers, which warn consumers of the associated risks. Therefore, the conclusion was made that regulatory intervention is necessary in South Africa. Following this, the recommendation was made to integrate cryptocurrencies into relevant existing legislation. It was recommended that regulation is the most effective method of combatting money laundering using cryptocurrencies.

  • Description: A number of theoretical and empirically proven studies have shown that the media exert varying degree of influence on audience members. The South African media framing and coverage of foreign nationals is a good example of this. Media critics and scholars hold that the way and manner foreign nationals are represented in South African media landscape contributes to the endemic xenophobic outbreaks in the country. (Endong, 2018; George & Aidoo, 2017). This study aims to critically analyse the influence of media reporting on xenophobic behaviours among students in selected South African universities. Part of its aim is to assert if there exist xenophobic behaviours among students learning in South African universities, which are influenced by the manner in which media reports have stigmatised foreign nationals. Therefore, this study looked at three South African universities, namely the University of Fort Hare, Alice campus, the University of KwaZulu Natal, Howard college campus and the University of Johannesburg, Soweto campus. Data for the study were collected using the qualitative methods, particularly the focus groups discussions and in-depth interviews. The findings of this study have revealed that xenophobic behaviours were evident among students, in lecture-rooms, as well as student residences. The participants also confirmed that the media’s focus and reliance on negative stereotypes and generalized information when representing foreign nationals were the main contributing factors to xenophobic behaviours, including its previous adopting of the words like Amakwerekwere, Aliens and Amagrigamba. In an attempt to discourage xenophobic behaviours, this study has therefore recommended peace journalism and Ubuntu journalism as alternative models for reporting xenophobic violence and conflict.

  • Description: The work of scholars and government programme have in the last decade or more paid a considerable amount of attention to the issue of fostering social cohesion under conditions on the increase rate of community- level upheavals and localized conflict. While some studies critique the South African government’s social cohesion strategy of 2012 in the main, others seek to identify its measurements and develop barometers to track its progress.

  • Description: The aim of the study was to critically assess the implementation of community development projects in mitigating youth unemployment in Mashonaland province of Zimbabwe. The study used the mixed method which dwells beneath a social phenomenon in order to draw substantiated findings. Data was collected using three method and these include, individual face-to- face interviews, focus group discussion and questionnaire administered to youth, government officials and the local authorities. The study was underpinned by the asset based community development theory and sustainable livelihood approach. Findings highlighted that the participants and the respondents meet the characteristics and criterion for selected community development projects aimed at mitigating youth unemployment. The study revealed that there has been lack on youth involvement in the planning and initiation of the youth community development projects which aim to mitigate youth unemployment and poverty eradication. It has been found out that the implementation process of the youth community development projects was surrounded by lack of knowledge and lack of the involvement of the youths, which resulted in the failure of mitigating youth unemployment and eradication of poverty. Although accessibility (to youth) of these community development projects was for all the community youth who were unemployed, it emerged that the access was not as indicated due to factors like, lack of funding, partisan distribution of resources. The study also realized that due to lack of involvement and proper implementation, the youth community development projects were not sustainable, which was evidenced by the high rate of youth unemployment and poverty levels. Furthermore, the study revealed that effectiveness of youth community development projects in v alleviating youth unemployment in the province has also been marred with pitfalls. Thus, there has been an increase of youth unemployment and poverty. Last but not least, the findings of the study revealed that there were a couple of challenges, which are rooted in partnerships, lack of youth inclusion and involvement, as well lack of involvement of other stakeholders with expertise on implementation of youth community development projects to eradicate poverty and alleviate youth unemployment. Regardless of the brilliant ideas and strategic interventions, the government lacks the practicality of the implementation of these intervention strategies. The study found that interventions were there. However, intervention entails a process which has different facets and obligates the government to function systematically to avoid default in the process of service delivery. It is recommended amongst others that the government and various stakeholders should take cognizance and develop mechanisms and strategies for poverty alleviation, growth, development and employment creation for the youth.
