- Description: Anecdotal reports in the South African citrus industry claim higher populations of false codling moth (FCM), Thaumatotibia (Cryptophlebia) leucotreta (Meyr) (Lepidoptera: Tortricidae), in orchards during the first three to five harvesting years of citrus planted in virgin soil, after which, FCM numbers seem to decrease and remain consistent. Various laboratory studies and field surveys were conducted to determine if, and why juvenile orchards (four to eight years old) experience higher FCM infestation than mature orchards (nine years and older). In laboratory trials, Washington Navel oranges and Nova Mandarins from juvenile trees were shown to be significantly more susceptible to FCM damage and significantly more attractive for oviposition in both choice and no-choice trials, than fruit from mature trees. Although fruit from juvenile Cambria Navel trees were significantly more attractive than mature orchards for oviposition, they were not more susceptible to FCM damage. In contrast, fruit from juvenile and mature Midnight Valencia orchards were equally attractive for oviposition, but fruit from juvenile trees were significantly more susceptible to FCM damage than fruit from mature trees. Artificial diets were augmented with powder from fruit from juvenile or mature Washington Navel orchards at 5%, 10%, 15% or 30%. Higher larval survival of 76%, 63%, 50% and 34%, respectively, was recorded on diets containing fruit powder from the juvenile trees than on diets containing fruit powder from the mature trees, at 69%, 57%, 44% and 27% larval survival, respectively. Bioassays were conducted to determine if differences in plant chemistry between fruit from juvenile and mature trees will have an impact on the susceptibility FCM to entomopathogenic nematodes (EPN), entomopathogenic fungi (EPF) and Cryptophlebia leucotreta granulovirus (CrleGV). No significant differences in the susceptibility of larvae reared on diets containing 15% fruit powder from juvenile and mature trees to EPN and EPF were recorded. Mortality of neonate larvae was significantly lower when placed on diets containing 15% fruit powder from mature trees (45% mortality) than diets containing 15% fruit powder from juvenile trees (61% mortality), after larvae ingested the lowest virus concentration tested, being 2 x104 OBs/ml. Data collected from field surveys showed significantly lower egg parasitism, virus infection of larvae and EPF occurrence in juvenile orchards than mature orchards. Egg parasitism was between 11% and 54% higher in mature orchards than juvenile orchards, with the exception of Mandarins during 2015, where egg parasitism was slightly higher in juvenile orchards, but not significantly so. A significantly higher proportion of larvae retrieved from mature orchards (7% of larvae) were infected with CrleGV than larvae retrieved from juvenile orchards (4% of larvae). A significantly higher occurrence of EPF was recorded in non-bearing and mature orchards, with 40% and 37% occurrence respectively, than in juvenile orchards, with 25% occurrence recorded. EPF occurrence in juvenile orchards increased significantly by 16% to 32% from the first to the third year of sampling. In contrast to results recorded in laboratory trials, similar or higher pest pressure in juvenile orchards than mature orchards did not always result in significantly higher levels of FCM damage under field conditions. FCM damage in juvenile orchards may have been lower than expected, as greater extremes of temperature and lower humidity were recorded in juvenile orchards, which would increase larval mortality. Results of this study showed that juvenile and mature orchards are significantly different and should be managed differently.

- Description: The acceptability of zero tillage amongst small-scale farmers is a challenge in the Eastern Cape Province as farmers have different strategies on how to manage residue. This situation is due to the limited information available on the benefits of implementing zero tillage, such as improving soil health. The Department of Agriculture and Agrarian Reform have been assisting small-scale farmers by subsidising them with the latest innovations, such as zero tillage. The main essence of these initiatives was to compensate farmers that are previously disadvantaged as a result of the apartheid system prior to 1994. Zero tillage has recently gained more attention as one of the most important farm practices due to its benefits for soil conservation and the elimination of greenhouse gases. The study was conducted at Magadla and Nkawu villages in Matatiele, Eastern Cape. The objective of the survey was to examine the influence of current residue management practices amongst Matatiele farmers in the light of the adoption of zero tillage practices. The data was collected using questionnaires and group discussions. The statistical package SPSS and Microsoft Excel were used to analyse data. The findings showed that the adoption percentages of zero tillage by small-scale farmers was 34 percent and 65 percent in Magadla and Nkawu villages respectively. Amongst the challenges that non-adopters faced were shortage of inputs, weak communication channels between farmers and coordinators, residue benefits to livestock and lack of proper monitoring and evaluation. Binary logistic model was adopted and used to analyse 13 independent variables that influence the adoption of mulching in the study area.

- Description: In South Africa there is pressure to deliver green building due to environmental issues such as climate changes, the energy crisis, as well as persistent water shortages. Although awareness and promotional effort have increased drastically concerning the adoption of green buildings, the South African design and construction industry is still lagging due to the conservativeness and slow rate of change in the construction industry. While enablers / facilitators have been recognised as opportunities to advance green building development, the South African built environment has not extensively explored the various possibilities to initiate enablers / facilitating conditions to enhance the adoption of green building. This study therefore investigates the critical factors impeding the adoption of green building and to explore the economic and non-economic facilitators / enablers regarded as the most important to stimulate stakeholders’ behavioural intentions to adopt green building. After an extensive review of literature with respect to barriers and factors that engender green building adoption, coupled with theoretical arguments relating change agents to construction innovation and sustainability theory, an exhaustive mixed-mode research approach was adopted. The sampling frame for the study was limited to four provinces, namely the Eastern Cape, Gauteng, Kwazulu–Natal, and Western Cape, given that 99% of the green building accredited professionals registered with the GBCSA are from these four provinces. The quantitative data was analysed using descriptive and inferential statistics, namely paired sample test, ANOVA test, Factor Analysis (FA), and logistic regression analysis (LRA). The qualitative data obtained across individual cases by means of a semi-structured interview was analysed using content analysis. In total, 106 professionals participated in the survey, and three respondents indicated their willingness and availability to be interviewed, hence three case studies were conducted. The results emanating from the study, inter-alia, indicate that the factors constraining the adoption of green building are categorised as: lack of information and incentives; inadequate skilled professionals; behavioural barriers; regulatory and steering factors, and the cost of green building. The results also indicate that green building consultants and environmental groups are classified as ‘innovators’, whilst architects are ‘early adopters’. However, government; municipalities, and general contractors are characterised as ‘late majority’. It was also evident from the empirical findings that the key attributes of adopters that encourage the adoption of green building were classified as: qualities of consultant team and contractor, and developers / clients’ experience. The perceived benefits of green buildings emanating from the findings were categorised as socio-economic, financial, and health and community benefits. The enablers that engender the adoption of green building were also categorised as: extended knowledge base and technical capacity; research and training of professionals; green lending incentives; progressive green building policy; economic incentives, and reward scheme and technical assistance. Two models have been developed using logistic regression model (LRM), model one (1) examined the predictable effect of economic and non-economic factors on the intention to adopt green building, whereas model two (2) examined the likelihood of the extent of green building adoption. The LRM results revealed five predictors and two control variables made a unique statistically significant contribution to model 1. The strongest predictor to enhance the intention to adopt green building was financial benefit (FB), recording an odds ratio of 9.1, which indicates that the likelihood to adopt is approximately 9.1 times more if financial benefits is evident. With respect to Model two (2), the LRM results showed that only two of the independent variables and three control variables contributed significantly to the model. The strongest predictor that determines the extent of adoption of green building was research and training of professionals (RTP), with odd ratio equal to 2.9. In effect, to engender the adoption of green building within the South African built environment, there is the need for an integrated and holistic approach forecasting on the importance of economic and non-economic enablers / facilitators in enhancing decision to adopt green building.

- Description: The thicket mosaic vegetation type known as Calcrete Bontveld is now only found at three sites within the Eastern Cape Province. Consisting of thicket-like bushclumps scattered among grassy dwarf shrubland, this vegetation is isolated from other systems due to its unique geographical location and the surrounding Valley Thicket. A strong similarity between the bushclumps of Calcrete Bontveld and the adjacent Valley Thicket has led to the aim of this study, which was to demonstrate that an association exists between these two vegetation types. To investigate this, two sites, namely Grassridge (natural vegetation on a mine) and Shamwari (natural due to its status as a reserve), were selected. This provided a unique comparison of the functionality of the two vegetation types and identified key processes responsible for the existence of this association. In terms of edaphic variables, soil organic content and field capacity, values were similar between bushclumps and thicket while soil depth was the greatest in thicket at both sites. At both sites, life forms, diversity and similarity indices were similar for bushclumps and thicket. By utilizing the Island Biogeography Theory, these bushclumps show an island-type origin and the distance between them and the adjacent Valley Thicket (mainland-type), as well as their size, influenced the association between the two vegetation types. Commonality of species between thicket and bushclumps are postulated to be tied to their dispersal mechanisms and fruit types. Bushclump isolation on flat-topped ridges excluded thicket species dispersed by autochory and anemochory. Zoochorous dispersal (by birds and mammals) was the common factor in the transfer of species between thicket and bushclumps as the latter is a large resource patch for fauna. The size of the bushclumps and their distance from the thicket influenced zoochorous dispersal. Larger and closer bushclumps attracted more birds and mammals than the small or more distant ones. These effects differ at the two sites due to the complex animal interaction that occurs in the Shamwari Game Reserve as opposed to the reduced animal interaction at Grassridge. This study suggests that an association exists between the bushclumps of Calcrete Bontveld and the adjacent Valley Thicket, and is reliant on the natural zoochory that occurs at each site.

- Description: Widespread reports of the poor governance within the State-Owned Enterprises (SOEs) has proliferated the media in South Africa over recent years. This progressive decline of governance structures has raised varied concerns, most of which are expressed as questions of note. For example, questions exist about the reasons why laws, regulations and policies that aim to ensure effective corporate governance practices have largely been ignored. Secondly, questions exist about the identities of those employees / executives within these enterprises, who are responsible for ensuring that good corporate governance practices are maintained within an organisation. Similarly, there is need to clarify the role of the audit committees in upholding good corporate governance practices within SOEs? This study aims to identify, describe and clarify the role(s) of the audit committee in preventing corporate governance failures within SOEs. A qualitative research methodology was utilised as the basis for collating data to develop an in depth understanding of the audit committee’s oversight responsibility within SOEs. In-depth individual interviews (n=6) were conducted with board members as well as members of the audit committee of a specifically selected SOE that had a history of compromised corporate governance practices and suffered severe financial losses. From the interpretation of the collated data, it was noted that the presence of a strong audit committee enables a more accountable environment that requires senior management to account for their actions openly and transparently. SOEs need to appreciate corporate governance as an asset to a company’s operations rather than as a poorly rationalised compliance requirement.

- Description: The aim of this research study is to explore the subjective views and experiences of black men who were perpetrators of domestic violence and have gone through a rehabilitation programme as a result. This paper also explores the connection between masculinity and domestic violence, and how perpetrators make sense of the concept of domestic violence and abuse. The reason underlying the study is to contribute to the fight against domestic violence, perpetrated by males, by understanding the root cause of the problem. This topic emerged due to the lack of sufficient academic papers on men as perpetrators of domestic violence, therefore the intention is to progressively close the gap and contribute to the already existing knowledge on the issue of domestic violence. The study comprised of four research participants gathered from different NGOs and thus different backgrounds. The sample comprised of two Black males and two Coloured males. It is worth noting that for the purpose of this study, black men refers to all men of colour. Thus, both African males and Coloured males fall under the same umbrella of Black men. An Interpretive Phenomenological Analysis from the Qualitative paradigm was used to analyse the data received from semi-structured interviews. The themes that arouse from the study were 1) Learning gender roles through observation; 2) Masculinity learned through teachings; 3) Misinterpreting African values; 4) Intoxication makes it easier to hit a woman; 5) Difficulty dealing with deep emotions; 6) Control and ownership in the relationship; 7) Gender roles forced by society; 8) Lack of consequences; and 9) Masculinity matures. The findings of the study is that masculinity is connected to men perpetrating domestic violence through misinterpreting African values that are taught by elders. Even though masculinity is taught to boys at a tender age, it was discovered that for some of the participants, masculinity is not stagnant but rather constantly changing as the individual grows in personality and life experiences, and thus their values change. As a result of this discovery, masculinity is also individualistic. These findings could assist in future research. Perhaps a much larger research focusing on evaluating, and later, developing rehabilitation programmes that speak to the individual experiences and beliefs of different South African males in order to accommodate the diverse cultures, and thus the beliefs that South Africa shares amongst its people.

- Description: This psychobiography focuses on the first 80 years of Gary Player’s career development. Gary Player is a famous South African golfer who has contributed towards business, sport, and charity. The psychological frame of referenced employed to interpret Player’s career development derives from Donald Super’s Life-span, Life-space Theory, which serves to substantiate this study’s focus on career development. This study employed a qualitative case study design. The research aims were (a) to describe Player’s career development, (b) to interpret it through Super’s theoretical framework, and (c) to assess whether Super’s theory is appropriate or suitable for the interpretation of an individual’s career development. Multiple primary and secondary sources of information were utilised to describe and interpret Player’s life history. These multiple sources aided in ensuring the trustworthiness and rigour of the study. The findings highlighted Gary Player’s life, with particular relevance to the periods of time that he spent on his career, lack of time that he spent on retirement, and his incorporation of his hobbies into his career. The discussion incorporated Donald Super’s theory into the findings and indicated that there are some aspects of Super’s theory relevant to describing Player’s career development, particularly within the growth stage. Throughout this study’s processes, the subject was treated ethically and responsibly during supervision by the researcher. This study contributed towards the body of knowledge on Gary Player, the on-going research of psychobiographies in South Africa, career development, and the applicability of Super’s theory.

- Description: Critiques of the ‘relevance’ of Psychology in South Africa and Africa have been raging for a number of decades now. Recent debates about decolonising Psychology and what is meant by African Psychology have been rigorous and necessary. In this commentary, I argue that in order for Psychology to move beyond Euro-American-centric epistemology and practice, these efforts need to be supplemented with the grounded praxis of research and literature collation. The epistemological, empirical, and conceptual knowledges that have been generated within the South African, African, and Global South contexts need to be brought together in coherent forms. As with other analytical processes, the grounded praxis of collating knowledges around a particular topic or approach allows for fresh insights and for the transfer of knowledges generated in context. Gaps in current research may be identified, debates on particular issues strengthened, and practice potentially improved. Drawing on two examples – textbooks and systematic literature reviews – and from my and colleagues’ work in conducting these kinds of collation work, I argue that: textbook writers should use grounded methodologies to generate texts based on South African, African, and Global South research, with reference to research conducted in the Global North being peripheral at best; and systematic reviews enable the cross-fertilisation of ideas from other social science research where psychological research is sparse. Funders should consider funding collation efforts.

- Description: Promoting high domestic savings rates in order to boost economic growth is one of the SADC macroeconomic targets. Based on both the Solow’s (1956) and the endogenous “AK” growth models that predict a positive relationship between savings and economic growth in a closed economy, and on the Aghion-Comin-Howitt’s (2006) hypothesis that assumes a positive relationship between savings and economic growth in an open economy, two separate empirical models were constructed to test the long-run relationship and the causality between savings and economic growth in the SADC region. To this end, annual time series data for ten SADC member states obtained from the World Bank Indicators over the period 1985-2015 were pooled. The Panel ARDL/Pooled Mean Group estimator developed by Pesaran, Shin and Smith (1997) was performed to analyse the data. The main findings are that domestic savings is positively related to GDP in an open economy, whereas in a closed economy, it is insignificant. In addition, the speed of adjustment revealed a bi-directional causality between savings and economic growth. However, the speed of adjustment is much slower when the model is estimated with savings as the dependent variable but faster when GDP is regressed as the dependent variable. Thus, SADC member states are encouraged to implement policies that promote domestic savings as well as attract foreign direct investments, in order to boost economic growth. GDP growth will, in turn, increase the level of domestic savings.

- Description: The study examined the impact of non-labour income, in the form of the Child Support Grant, on a mother's labour market participation. The key question aimed to determine whether the Child Support Grant had a positive or negative impact on grant beneficiaries in accessing paid work and income. The primary focus of this study is on the impact that cash transfers have on recipients’ labour market participation. The focus is on these women, mainly to identify the causal effect of receiving a child support grant on their labour market participation. Location of focus was the New Brighton and Kwa Zakhele townships, since they have the highest number of social grant beneficiaries in Nelson Mandela Metro Municipality. An analysis of 101 questionnaires reveals that most of the grant recipients are either unemployed or underemployed. These beneficiaries do understand that the grant is meant to provide for the needs of the child concerned; however, because of their socioeconomic circumstances, the beneficiaries utilize the grant for other household purposes. Many of the respondents are actively job seeking but do not utilize the money for job seeking purposes; they mostly utilize it for household expenditure like groceries and electricity. The descriptive method was used to analyze the data and to find responses to the research questions and objectives. The results showed that the determinants of labour market participation by this group are multiple: for example, behavioral, loss of hope of ever finding a job, skills shortage or lack of work experience, lack of qualifications, and so on. Secondly, lack of government support for those who are keen to start self-generating projects leads to further despondency among those trying to find ways and means of generating income.

For cases of m, the number of fuzzy subgroups is _rst given, from which the general pattern for G is achieved. Murali and Makamba discussed the number of fuzzy subgroups of Zpn _ Zqm using the cross-cut method. A brief revisit of the group Zpn _Zqm is done using the criss-cut method. The formulae for _nding the number of distinct fuzzy subgroups in each of the cases is given and proofs provided. Furthermore, we classify the fuzzy subgroups of the group Zp1_Zp2__ _ __Zpn for p1; p2; _ _ _ ; pn distinct primes and n 2 Z+ using the criss-cut method.

- Description: The elimination of pay discrimination and the introduction of equal remuneration has been advocated internationally since the early 1950s by conventions set out by the International Labour Organisation (ILO). The aim of the International Labour Organisation is to improve working conditions universally, remove discrimination based on gender and establish fair rates of remuneration. In South Africa, regulations were promulgated on 1 August 2014 based on the conventions set out in the ILO, in the newly-amended Employment Equity Act. The amendment to section 6(4) of the Employment Equity Act states that a difference in the conditions between employees employed by the same employer, performing the same or substantially the same work or work of equal value based on any one or more grounds of unfair discrimination listed in subsection (6)1, is unfair discrimination. The introduction of this amendment, therefore, brought about an improved legal framework for employees to bring forth unequal remuneration claims. The doctrine of equal pay for equal work is nuanced owing to the lack of understanding, widespread forms of discrimination as well as interpretation of the law. This is experienced internationally and across many jurisdictions. The jurisdictions focused on in this study include the United States of America, the United Kingdom, India and Australia. The comparative study reviews the current equal pay for equal work law in these jurisdictions, and could prove to be useful guidelines to assist with the expansion of the doctrine within the South African legal context. Pioneer Foods (Pty) Ltd v Workers Against Regression (WAR) and Others was the first case brought forth to the Commission for Conciliation, Mediation and Arbitration since the amendment to the Employment Equity Act. A comprehensive analysis of this case has been set out in the treatise. Finally, the treatise concludes with inadequacies in the current legal framework, recommendations to resolve these inadequacies, the future of equal pay for equal work and proposes practical key learnings for human resources practitioners.

- Description: This thesis reports on an investigation into the features of an English for Academic Purposes (EAP) course that may promote or constrain students’ success at the Namibia University of Science and Technology (NUST). Work by the New Literacy Studies has problematised what it means to be academically literate and has critiqued the notion of skills training in Higher Education. This study sought to develop an understanding of what the coursework writers’ and lecturers’ priorities were in designing and assessing academic literacy as expressed in the English for Academic Purposes (EAP) module, and to explain contradictions. As part of this process, it sought to identify the module’s strengths and weaknesses in terms of an understanding of literacy as a social practice, and to recommend changes if necessary. My interest in this module is a result of two interrelated factors. Firstly, as a novice part-time lecturer at NUST, I became concerned at the prevailing high EAP failure rate, which suggested that the course was not in fact promoting the academic literacy of the students. At the same time, my own attempts at ‘equipping’ students with the required academic literacy skills were frustrating. Both these factors suggested that the design and assessment of the course might be misaligned with its purported aims. To carry out this research, I employed an interpretive paradigm using a qualitative approach. I draw on theories in the field of academic literacies by Gee, Street and Lea. The methodology for the study was a document analysis of coursework materials and assessments, supplemented by interviews with available course designers. The key finding of the research is that the aims of the module are undercut by its structure and presentation. The design and assessment tasks of this module, while they aim at giving epistemological access through the development of students’ academic literacy skills, are unlikely to achieve it. This finding explains to some extent the poor throughput rate of the course.

- Description: The main objective of this thesis is to understand and explain the ongoing construction of livelihood activities by urban households in the low-income high-density area of Budiriro, Harare, Zimbabwe in a context characterised by systemic crisis and a general decline of the national economy. The study utilised a mixed methods research approach, which combined both qualitative and quantitative research, including a survey, life histories and focus group discussions. The thesis discusses a diverse range of livelihood activities of Budiriro households, such as formal employment, informal trading and agricultural activities, and the ways in which households seeks to diversify their livelihood portfolio. It does this by way of also examining the contemporary and historical factors influencing the livelihood activities pursued by these households, along with the shocks and disturbances encountered and experienced by households in trying to construct viable livelihoods. The thesis makes useful contributions to the existing literature on livelihoods studies. Firstly, the thesis disaggregates the households by showing the existence of three wealth categories in Budiriro and the varying livelihood strategies of households in different wealth categories. Secondly, the study highlights the significance of intra-household dynamics in Budiriro for livelihoods as well as of inter-household kinship networks, which transcend the urban space and entail multi-spatial livelihoods. Thirdly, the thesis examines livelihoods over time, such that it goes beyond a strictly synchronic examination, therefore providing a diachronic analysis of diverse and complicated livelihood pathways. Finally, the Livelihoods Framework is located within broader macro-sociological theorising including the work of Pierre Bourdieu. In this respect, important insights arise about livelihood choices and practices in the light of ongoing debates within sociology about human agency.

- Description: The main objective of this thesis is to understand and explain the ongoing construction of livelihood activities by urban households in the low-income high-density area of Budiriro, Harare, Zimbabwe in a context characterised by systemic crisis and a general decline of the national economy. The study utilised a mixed methods research approach, which combined both qualitative and quantitative research, including a survey, life histories and focus group discussions. The thesis discusses a diverse range of livelihood activities of Budiriro households, such as formal employment, informal trading and agricultural activities, and the ways in which households seeks to diversify their livelihood portfolio. It does this by way of also examining the contemporary and historical factors influencing the livelihood activities pursued by these households, along with the shocks and disturbances encountered and experienced by households in trying to construct viable livelihoods. The thesis makes useful contributions to the existing literature on livelihoods studies. Firstly, the thesis disaggregates the households by showing the existence of three wealth categories in Budiriro and the varying livelihood strategies of households in different wealth categories. Secondly, the study highlights the significance of intra-household dynamics in Budiriro for livelihoods as well as of inter-household kinship networks, which transcend the urban space and entail multi-spatial livelihoods. Thirdly, the thesis examines livelihoods over time, such that it goes beyond a strictly synchronic examination, therefore providing a diachronic analysis of diverse and complicated livelihood pathways. Finally, the Livelihoods Framework is located within broader macro-sociological theorising including the work of Pierre Bourdieu. In this respect, important insights arise about livelihood choices and practices in the light of ongoing debates within sociology about human agency.

- Description: The Eastern Cape Province have high numbers of livestock but high poverty rates remain very high. This study therefore, aimed to determine the contribution of smallscale livestock farming to rural household income in the King William’s Town area in five rural areas. Literature shows that the livestock sector contributes 40 percent of global value of agricultural output and supports the livelihoods and food security of almost a billion people. The data collected for this research were both quantitative and qualitative and cross-section design was employed for the research. The study used both simple random sampling and availability sampling to select 125 sample households, 25 respondents from each village. Descriptive statistics was used in the analysis of demographic and socio economic characteristics of households where graphs and tables were used to present the relevant information. Probit regression model was used to determine factors influencing the decision to practice livestock production and marginal analysis was calculated to determine the effect of changes of individual variables. For the assessment of the contribution of small-scale livestock farming to household income Propensity Score Matching (PSM) model was fitted. Results show that the highest percentage of livestock kept by households in 5 villages is 56 percent for poultry and the lowest percentage is 2 percent for pig. The main source of income for many households in the study area was the income from pensions and grants but livestock farming is also contributing to household’s income through income generated from sales of livestock for customary events such as traditional rituals and celebrations, lobola, funerals and weddings. Many of the households have secondary education and the reason might simply be that in olden days’ parents had no money to pay school fees of their children and that limited children to go further with their studies. The results of the marginal effects estimates for the probit model suggest that changes in the number of livestock sold would have important effects on household incomes. There are various challenges that livestock producers are facing in their production and the major challenge that households are facing is parasites and diseases as they decrease number of livestock kept by households. Parasites and diseases suck blood, causing the animals to become weak and sometimes resulting in high mortality rate. It is recommended that livestock producers should be made aware of the impacts of various challenges that affect livestock farming through awareness creation programmes and suggest solutions to overcome those challenges.

- Description: Small-scale fisheries are known to provide food and income to millions of people around the world, but their role and existence is often ignored in development planning. The growing human demand for animal protein has become one of the foremost world challenges for which aquatic organisms have a significant role to play. In South Africa, small-scale fisheries have been recognized since the end of Apartheid, but the extent of the contribution of the sector to rural livelihoods and food security is not well understood. Using data drawn from a sample of 80 fishers in the coastal community of Hamburg, Eastern Cape, this dissertation presents an assessment of the contribution of small-scale fisheries to rural livelihoods, income and food security. The primary data were collected from the fishers using a structured questionnaire and non-probability sampling. The data were analysed with the assistance of descriptive techniques and a few simply statistical tests. The results of the study indicate that fishers in Hamburg catch a wide range of fish, which include wild kob, octopus, spotted grunter, white/black mussel cracker and white steenbras. Fishers in the study area are not solely dependent on small-scale fisheries for their livelihoods, income and food security, but generally supplement their welfare payments with fishing in order to sustain their livelihoods. About 78percent of the surveyed fishers depend on government grants, including old age grants, child support grants and social care grant. In terms of employment, 15percent of the surveyed fishers are casually employed, while 6percent are formally employed on a contract basis. Although they are not only dependent on fishing, nevertheless fishing is an important source of livelihood, income and food security. About 37percent of the fishers harvest marine resources for home consumption, while 7percent harvest solely for income, and 56percent harvest for both home consumption and income. Income generated from fisheries is approximately R935 per month and is used to buy food, electricity, fishing equipment and other household needs. The findings from this research underline the need for interventions such as coordinated institutions, improved infrastructure, improved monitoring and enforcement systems, as well as improved access to permit/fishing rights for sustainable use of marine resources.

- Description: Water hyacinth is invasive in many countries, where it reduces aquatic biodiversity and limits water resource utilisation. Biological control of water hyacinth has been successful in South Africa, but has suffered from a lack of empirical data to prove causation. Insect exclusion trials were conducted to quantify the contribution of Neochetina eichhorniae and N. bruchi to the integrated control of water hyacinth on the Nseleni River, South Africa. Insecticide was not expected to induce phytotoxicity, but would prevent weevil damage in water hyacinth plants; and weevil herbivory was predicted to reduce plant petiole length, and above/below surface biomass. Results showed that insecticide had no phytotoxic effects and excluded weevils for 3 weeks, providing a baseline for field applications. Biological control on the Nseleni River directly affected water hyacinth biomass and petiole length, but did not affect plant cover. Plants subject to weevil herbivory demonstrated reductions in above and below surface biomass and had shorter petioles compared to insect-free plants. Dead biomass was also higher in biological control treatments. Biological control strongly affects plant size, biomass and vigour; however, further integrated control is required to facilitate reduction in mat cover, which is the goalpost for successful control of floating aquatic plants.

- Description: The long history, serious and multiple negative consequences, and the global prevalence of human deception inspired the current correlational study. According to certain researchers and practitioners, the polygraph has emerged as one of the most promising methods to detect deception. Although its use has not been without controversy, it is still one of the most frequent means used to detect human deception. In an attempt to address the continued reliance on the polygraph, often in the absence of other evidence, the current study aimed to explore and describe the relationship between final polygraph test results and nonverbal behaviour observations during the pre-interview of the polygraph test. The research design was a correlational study, which explored and described the relationship between specified nonverbal behavioural observations, and deceptive and non-deceptive indicator results, of the participants taking the polygraph test. The nonverbal movements of the head, shoulders, hands and feet were the focus of the study. The research hypothesis of the study was that participants who were identified as deceptive on the polygraph would demonstrate significant statistical differences in specific nonverbal behaviours compared to non-deceptive participants. The results indicated significant statistical difference between the hand movements between the deceptive and the non-deceptive groups who participated in the study. The nonverbal behaviour related to the two groups’ hand movements was found to show significant differences, specifically related to five specific domains, hand hold symmetrical action, right arm/hand still, left hand/finger actions, touch behaviour, and thumbs up and downwards movements. The data were described and analysed by means of descriptive and inferential statistics and significant correlational findings were discussed in relation to the relevant published literature.
