- Description: This research is premised on the understanding that alternative forms of media emerge to deal with specific ideological projects and, as such, must be seen as satisfying a specific need at a specific point in time. Using the case of a weekly newspaper, The Southern Star which was in circulation from January 2012 to June 2012, this study sought to understand the factors that led to the establishment of the newspaper, what it sought to achieve, how it went about putting that into practice, its message in relation to debates emanating from the ‘Matabeleland Question’ and also the factors that led to the its collapse. In order to address my research questions, I adopted a two stage research design qualitative content analysis and semi structured in depth interviews. In locating the study within the qualitative epistemic understanding of research, it was clear from the qualitative content analysis of 13 editions of the publication and in depth interviews held with 15 respondents that the newspaper was set up with the aim of serving a marginalised section of the population (in this instance the Ndebele) by providing them with a platform to articulate issues affecting them. It also sought to ‘speak’ the ‘unspoken’ within the mainstream media by focusing on Matabeleland identity politics. It achieved this by creating content around the Gukurahundi genocide, Matabeleland development, Matabeleland history and Matabeleland heroes. The newspaper also sought to emancipate the people from the South by advocated for social, cultural, economic and political justice as a resolution to the ‘Matabeleland Question’. However, the newspaper failed to sustain operations due to lack of advertising revenue. As a result of the constraining political environment in which the newspaper operated, potential advertisers were afraid of placing advertisements in the newspaper because of the nature of the content produced, which in view of Zimbabwe’s rival ethnic history, could easily be labelled ethnically divisive. Also, being a new player in the market worked to their disadvantage as prospective advertisers opted to place their adverts in “tried and tested” publications (Zimpapers and Alpha Media Holdings). Additionally, because of poor management, roles were not clearly defined and hence the newspaper failed to operate as a business enterprise. As noted during interviews with junior reporters, there was little or no experience at management level. The paper lacked a coordinated circulation strategy and from inception, was never officially launched, which resulted in the failure to reach significant audiences.

A phenomenological investigation of a female leader's perceptions and experience of discrimination in the work place

- Description: Women are now making their mark in virtually every economic sector including traditionally male strongholds of engineering, heavy transport, construction and manufacturing. Probably the most spectacular progress by women has been in the public sector. Many women now have voting rights, follow careers which demand that they work outside of the home, enjoy professional status equal to their male compatriots, occupy top leadership positions in their societies and, furthermore, fulfil their traditional roles of wife and mother. The present study is an attempt to explore a female eader’s perceptions and experience of discrimination in her place of work. The problem has been that although there have been significant changes in women’s increased representation in recent years, it is believed that women who succeed in obtaining top management posts still have to deal with unfair barriers. These need to be more carefully explored and understood. In this study I focus on one female leader’s perceptions and experiences of leadership in an institution of higher learning. The advantages and disadvantages of such a small case study are discussed later. A phenomenological approach was used for obtaining information pertaining to the phenomenon “female leadership”, because phenomenology does offer ways of understanding not offered by other research methodologies. It enables the researcher to enter the lived world of the researched, and understand events and perceptions from a fresh point of view. A semi-structured interview was used to allow the respondent freedom to elaborate on responses in whatever manner she wished. The results obtained indicate that women are in a life-world in which, apart from the general experiences shared with their male counterparts, they are also exposed to many other forms of discrimination. Some of these are subtle, and result from years of socialisation into perceived gender role expectations. I hope that what I have discovered may help to contribute to the small but growing body of literature that seeks to understand women leaders’ experiences, and perhaps in time play a role in enhancing their relative position in education and society at large.

(See Acts 15, Galatians 2, etc.) It has since then known division into East and West, into Roman Catholic and Protestant, and into the hundreds and even thousands of denominations and sects which we know today, not to speak of the schisms between 'modernism' and 'fundamentalism', between Calvinism and Arminianism, and between 'High' and 'Low' churchmanship.

- Description: This study used a quantitative approach to evaluate the application of the performance management and development system in the Eastern Cape Department of Health, from the perspective of employees. The evaluation report has three sections that are designed as interrelated but stand-alone documents. Section One is written as a report directed to the Eastern Cape Department of Health. Section Two is a review of the relevant literature that was conducted to review the existing literature related to the application of performance management and development systems, and underpinned the construction of the questionnaire. Section Three provides a description and justification of the design of the research, as well as describing the research procedure followed. Pertinent components of Sections Two and Three are extracted from these sections and included in the report in Section One. The literature review focused on the following areas: the purpose of performance management, components of the performance management process, challenges/ criticism of performance management systems, integration of performance management with other systems and the effectiveness of performance management system. The results revealed that about 74% of employees disagree that management is committed towards the successful application of the performance management system. This finding concurs with the literature. For example, De Waal and Counet (2009:367) argue that one of the problems in the application of performance management system is that the management lacks commitment to the implementation of a performance management system. Systematic sampling (Leedy and Ormrod, 2010) was used to select 120 participants in three Departmental programmes or clusters from grade levels six to 15. The researcher distributed the questionnaires to every fifth person of the population electronically using SurveyBob, which is an on line survey tool. The collected data was then analyzed using Excel software. The findings indicated that although overall employees are not satisfied with the application of the PMDS system in the Eastern Cape Department of Health, there were some successes. Nevertheless, the challenges outweighed successes of the system. The challenges that resulted in the failure of the system include poor communication, a lack of understanding of the system by the employees and a lack of knowledge with regards to the integration of PMDS with other initiatives and plans already in place. Page 4 There were positive views with enabling factors and these were work plans that are mutually agreed upon between the employee and their supervisors and are aligned to departmental strategic priorities. Constraining factors included the low levels of commitment of the management to the application of the PMDS processes, review meetings not being undertaken on a quarterly basis, and a lack of written outcome reviews. The majority of the study participants believe that the PMDS lacks fairness in its implementation. Recommendations were made on the basis of the gaps that were identified so as to improve the application of the performance management system in the Eastern Cape Department of Health. It is therefore recommended that the Department should ensure that training and development of employees on the PMDS takes place to enhance manager’s understanding of the policy. This will enable managers to understand the important role played by performance management in their day to day activities. A performance management and development system needs to be integrated with all other processes to be effective. On-going communication of the PMDS policy should be considered. Accountability of managers to the Accounting Officer and submission of quarterly reports are imperative to ensure their compliance. In conclusion, dissatisfaction outweighs satisfaction of the employees with regards to the implementation of the PMDS system.

- Description: This study aimed to assess the implementation of citizen centric strategies for social grant service delivery in the Chris Hani District and if SASSA is still living up to its promise. SASSA claims it will always pay the right social grant, to the right person, at the right time and place. This study aimed to understand and assess the different strategies of SASSA towards enhancing citizen experience in delivering social grants. The study’s objective was to assess citizen experience regarding the SASSA social grant payment systems, the social grant application processes, and SASSA communication and advocacy programmes. To conduct this study, a qualitative research methodology was employed. The population sample comprised of SASSA officials in the Chris Hani District. Semi-structured interviews were conducted with SASSA officials. The findings of this study reveal that SASSA did well to improve application turnaround time from 90 days to one day. Even so, payment methods must be improved. The recommendations suggest that SASSA should consider insourcing the function of paying social grants and consider opening the closed pay-points, as beneficiaries are struggling to travel to the remaining opened pay-points. The findings also proposed aligning the SocPen and MIS.

- Description: The purpose of this study was to investigate the extent to which the Beacon Bay Community Police Forum in the East London area has implemented the Community Police Forum (CPF) uniform constitution. The main research question of this study was: To what extent has the Beacon Bay Community Police Forum in the East London area implemented the uniform Community Police Forum (CPF) constitution? The theoretical framework that guided this study was the broken windows theory. The literature review looked into the following: existing knowledge based on the assessment of the implementation of the uniform CPF constitution by the Beacon Bay Community Police Forum, the regulatory framework and an overview of the role and functions of the community police forum (CPF) in South Africa, lack of awareness and representativeness as challenges to community police forums effectiveness, inadequate resources in the implementation of an effective community policing forum, lack of trust between the police and the community and the issue of corruption as challenges in the implementation of CPF. The qualitative research method was used in this study. The case study design was also used. The researcher used the purposive sampling technique to select six community members and four community executives of the Beacon Bay CPF in the East London area. Face-to-face in-depth individual interviews were used to gather in-depth data. The manual method of analysis was used. The researcher analysed the data by capturing the patterns and direct words of the participants who were interviewed through note taking. Themes were drawn from the responses of the participants and analysed. Some of the findings were that: Community members did not know exactly when the CPF was implemented, the CPF was not effective, community members did not attend CPF meetings and had negative attitudes towards CPF, the police worked better with the rich people rather than the poor ones and there were some influences of politics in the CPF. In addition, the resources lacking at the CPF were: SAPS staff, shortage of police stations and insufficient vehicles at the police stations. Furthermore, some police worked hand-iniv hand with the criminals and the repercussions of poor trust between the community and the police included: community members taking the law into their own hands, poor handling of criminal cases, and escalation of crime in the community. Some community members noted the positive effect that the implementation of the community police forum had as they could now engage the police directly on matters relating to crime and how they think such challenges can be addressed. The researcher made some recommendations towards an effective implementation of the Community Police Forum in Beacon Bay in East London.

- Description: Purpose: with the recent establishment of Small Business Development department, the ministry is tasked and will be responsible for ensuring that the business environment is enabling for new Small to Medium businesses. The real issue and the point of interest in researching this particular dissertation is the available literature around the issue of the SME sector which indicates that new SMEs in South Africa do not move from the first stage (existence) to other stages such as survival, success, take off and resource maturity. The study seeks to inaugurate two specific challenges (difficulties in accessing finance and to examine if there is sufficient non-financial SME incubators and mentorship programs post funding allocation). The area of study focused on SMEs that are concentrated in highly populated areas of Gauteng. Methodology: The study was conducted using qualitative research and a questionnaire was used as a data collection tool. The researcher was able to get valuable information on stakeholders in the SMME sector. This was done through the use of questionnaires to businesses, government funders and incubators. Results: when posed with a question of the start-up capital, a mere 17% responded to having obtained financial assistance from government institutions, 20% from friends and family while a massive 60% indicated they have used own capital to start businesses. When the researcher posed the question of the reasons that often leads to failure, approximately 23% of businesses mentioned lack of working equipment as the core reasons for the business failure while 17% indicated that lack of business opportunities or rather contracts of supply from government departments as the main impeding factor which resulted to failure. In terms of the availability of incubators, approximately 67% of respondents indicated that there were no business incubators available in their areas of business. Approximately 57% of businesses mentioned the inability to obtain loans from government funding institutions was the major business constraint that often leads to failure. The researcher posed a question to business incubators personnel that participated in the study to gain perspective as to why do they think SMEs fail within the first year of operation. Approximately 40% of respondents alluded that, barriers to entry by big corporates in South Africa force Small and Medium Enterprises out of businesses. Other participants added that the South African government procurement system does not provide opportunities to small businesses due to lack of experience. All government funding institutions participants mentioned that in most cases SMEs finance applications are rejected due to the fact that businesses fail to present viable business proposals that show the ability for business to remain operating for a long time Implications: The above analysed study findings indicate that there is a huge gap between small businesses and government funding institutions in terms of the awareness of the available financial support to SMEs. From the government perspective, it was indicated that businesses submit business plans that are not viable. There needs to be the middle ground where business plans compilation support currently provided by SEDA awareness should be spread across SMEs operating in the highly populated areas of Gauteng. Recommendations: Access to finance is a major constraint hindering the growth and success of small enterprises. The South African government has established a number of financial support programmes aimed to assist SMEs. With these financial support programmes, most of the SMEs are unsuccessful due to the fact that they cannot easily access those funds and as a result they remain stagnant for a very long time or end up shutting down. Conclusion: The effect of credit rationing is the potential loss of opportunity and or reduction in the scale of a business, neither of which is a desirable outcome. At the most fundamental level, there are lost opportunities for the borrower and the lender. There are implications for the wider economy also. SMEs are a key source of innovation, competition and choice.

- Description: Purpose: with the recent establishment of Small Business Development department, the ministry is tasked and will be responsible for ensuring that the business environment is enabling for new Small to Medium businesses. The real issue and the point of interest in researching this particular dissertation is the available literature around the issue of the SME sector which indicates that new SMEs in South Africa do not move from the first stage (existence) to other stages such as survival, success, take off and resource maturity. The study seeks to inaugurate two specific challenges (difficulties in accessing finance and to examine if there is sufficient non-financial SME incubators and mentorship programs post funding allocation). The area of study focused on SMEs that are concentrated in highly populated areas of Gauteng.

Composing affect: reflection on configurations of body, sound and technology in contemporary South African performance

- Description: This thesis engages with experiential performance modes through the lenses of phenomenology and affect theory. Because experiential performance relies per definition on personal, subjective ‘experience’, specific responses cannot be anticipated. However, by attempting to compose ‘affect’, a performance has the potential to ‘move’ an attendant towards response. Deleuze and Guattari define ‘affect’ as “an ability to affect and be affected….a prepersonal intensity corresponding to the passage from one experiential state of the body to another and implying an augmentation or diminution in that body’s capacity to act” (1987: xvi). One current strategy for manifesting affect in performance seems to be the ways in which different configurations of body, sound and technology are employed. The body is the means through which sound is received or ‘experienced’ in the phenomenological sense, but it can also act as a source for sonic material. The body is furthermore the means by which sonic technology is manipulated. It is the complex, reverberating relationships between body, sound and technology, and their potential for eliciting affective transformation, which is the focus of my enquiry. In the first chapter I unpack the roles of the natural phenomena, body and sound, and their complex relationships to affect. The chapter serves as philosophical basis for the rest of the investigation, and draws largely on works by philosophers Susan Kozel, Maurice Merleau-Ponty, Brian Massumi, Gille Deleuze and Félix Guatarri and sound theorists Don Ihde, Marshall McLuhan, Brandon LaBelle and Frances Dyson.In the remaining three chapters I discuss current South African theatre works that employ the strategy of placing emphasis on sound, sonic technology, and its relationship to the human body. These works are my own piece herTz (2014), Jaco Bouwer’s pieces Samsa-masjien (2014) and Na-aap (2013), and First Physical Theatre Company’s Everyday Falling (2010). While they range from being plays to physical theatre performances to performative experiments, they all place specific emphasis on sonic devices, drawing attention to sound by revealing microphones, speakers, midi boards, etc. to the attendants, and including the generation and manipulation of sound in the action of the performance.

- Description: This study aimed at evaluating the effects of heated Mucuna pruriens seed meal on the blood serum lipid profile and bone quality parameters of broiler chickens. A total of 120 day-old unsexed Cobb 500 broiler chicks were randomly allocated for the 4 treatment diets (T1, T2, T3 and T4) containing 0, 10, 15, and 20% heated Mucuna pruriens seed meal. The birds were reared on wood shaving floor pens for 35 days. Birds were humanely slaughtered by severing the jugular vein using a sharp knife. Blood was collected into a tube, centrifuge and analyzed for a lipid profile analysis (total cholesterol (TC), high density lipoproteins (HDL), low density lipoproteins (LDL), triglycerides (TCD) as well as aspartate transaminase (AST) and alanine transaminase (ALT)) by enzymatic diagnostic kits (Diasys diagnostic kits). Both drumsticks severed using a sharp knife. After boiling in the water at 100°C for 10 mins the tibia bones were taken, air-dried for 96 hrs at room temperature and measured for weights. Bone length, strength, moisture and ash content as well as morphology were measured. The blood lipid profile of birds fed T1 was high (P < 0.05) for all the parameters measured, while T3 had the lowest (P < 0.05) profile. T2 and T4 had the same profile. ALT was found to be highest (P < 0.05) for T4 (5.27 ± 0.207/L) and lowest (P < 0.05) for T2 (4.67 ± 0.333/L) while AST was highest (P < 0.05) for T2 (320.13 ± 28.851/L) and lowest (P < 0.05) for T3 (208.47 ± 10.059/L). Treatment diet 3 (T3) was observed decreased bone quality among all diets; with the lowest (P < 0.05) bone strength (188.55 ± 12.039N), bone length (8.59 ± 0.131cm) and morphology (1.69 ± 0.058). Mucuna pruriens seed meal inclusion in broiler diets reduces blood serum lipids and 20% inclusion levels have no adverse effects on the bone quality attributes

- Description: South Africa and other African countries are faced with high levels of food insecurity and poverty levels as a result of slow growth of the macro economy and weak or sluggish rural development. Irrigation scheme development is seen as an important strategy to address the challenges faced by households in rural areas and restores growth and enhanced livelihoods. While the international experience shows that Irrigation schemes are potentially transformative of poor communities and have been operational for many years now, there is no marked improvement in living conditions of rural households in terms of livelihoods and income. This raises the question as to whether or not the schemes are viable from a socio-economic perspective and whether or not there are reasons for concern and revision of the policy framework for smallholder irrigation schemes. As a result of that, the broad objective of the study was to evaluate the contribution of smallholder irrigation schemes to household income and food security of rural households in Idutywa village of the Eastern Cape Province in South Africa. Specifically, this research investigated the major factors that influence their performance, impact of irrigation farming on rural livelihood and household food security as well as identifying the possible opportunities of production that would improve their performance. The study was carried out in Idutywa villages of the Eastern Cape Province in South Africa and employed survey data obtained from 107 households. The study employed a cross-sectional research design and the study employed stratified random sampling. The study made use of descriptive and inferential statistics to estimate the central tendency and dispersion as well as testing the hypothesis that there is a difference in the contribution between irrigators and non-irrigators using STATA and SPSS. Probit regression model was used to estimate factors that influenced the performance of smallholder irrigation schemes. The descriptive statistics employed included means, percentages and frequencies on the socio-economic characteristics of households in the study areas. The results show that females were dominant with a representation of 66.7 percent. The majority of households were aged and the mean age was 65 years. High level of illiteracy in the project area was revealed by the data. The average number of years, households spent in school was between 6 years to 10 years in school. Farming was found to be the major agricultural economic activity. Sixty-three (63 percent) were full time farmers. The results further show that household size ranges between 1 to 5 persons. The households were shown to be mostly dependent on social grant with household income hovering around R 1 000. The results from propensity score matching revealed that irrigation exerts a positive impact on household income. This provides sufficient evidence that irrigation schemes do make a contribution to rural livelihoods through their effect on household income and food security. This implies that government should continue investing in irrigation schemes as part of a strategy to grow the rural economy and improve rural livelihoods. This is in line with the Agricultural Policy Action Plan (APAP) and National Development Plan (NDP) of South Africa. Probit analysis suggests that age of the households, household size and market were some of the key determinants that positively influenced households’ decision to participate in smallholder irrigation schemes while access to credit had significant but negative effect on households’ decision to participate in smallholder irrigation schemes. Based on the findings highlighted above, it is recommended that addressing such barriers may create enabling conditions that would encourage households to access and participate more effectively in smallholder irrigation schemes.

- Description: Change is a common phenomena in business organisations today. The turbulent environment is exerting a significant influence on organisations to make continuous changes in their internal environment in an attempt to improve performance and achieve competitiveness in the marketplace. The human factors which confront organisations undergoing change have not been thoroughly investigated in Sub-Saharan Africa. The present study aimed at investigating human issues affecting the performance ofan organisation located in an Afiican country. Data was collected using semi-structured interviews and focus groups. Twenty interviews were conducted with employees randomly selected from all the levels of the company, namely attendant, operator, supervisory, middle and top management. Five focus groups were carried out with employees from different employee categories. Both sets of data were analysed using grounded theory. The findings showed that there were several problems in the company including insecurity, lack of opportunities for employee development, autocratic management style, lack of participation in decision making, substandard performance, ineffective human resources systems and lack of adaptation to technology. It was suggested that the problems resulted from the clash between organisational cultures in the company. At one level, there was a clash between the local workers' socialist organisational culture and the expatriates' capitalistic organisational culture. At a more deeper level, the clash appeared to be between the local employees' collectivistic sociocultural values and the expatriates' individualistic value system. These findings have significant implications for managing change in organisations with diverse cultures.

- Description: This study was conducted as a case study at the rural Ethridge Junior Secondary School which is located in the Eastern Cape Province of South Africa. The aim of the study was to investigate how school gardens could be used to teach environmental activities in the Technology Learning Area at senior phase. The study examined how environmental activities in the school garden can be used to develop technological concepts and knowledge and for developing technological problem-solving abilities. Furthermore, it examined the relationship between technology, society and environment, and how structural and socio-cultural factors influence the use of environmental activities in the school garden. The overall approach was a case study. The data was generated using qualitative methods such as interviews, observation, workshops and document analysis of learners’ work. Of all the research tools used, the interviews and observations were the most fascinating and informative methods. The study focused on various activities undertaken by Grade 8 learners in their Technology Learning Area. These activities were compost making, planting and irrigating. The study showed how learners from poor rural homes can use available resources and suitable technology processes to plant vegetables. In terms of resources, virtually all resources used in the study were free, sourced locally and/or borrowed. This indicated that even in poor, rural areas materials are available to make structures and complete activities. In terms of available suitable technology, learners in the study explored the use of old car tyres for planting containers that can be easily transported. They also, using easily available resources such as tin cans, explored how to design and construct an effective, low-water consumption, low cost irrigation devise. The study explored the achievement of Learning Outcomes (LO) using the school garden. This study uses the school garden as a teaching aid to achieve the three main LO’s in the Technology Learning Area (LA). This study has also indicated that LO’s are sometimes intertwined, that is to say that more than one can be achieved at the same time. The three activities (compost making, planting and irrigation) were used to attain the required LO’s. The study indicates that LO 1 (related to applying technological processes and skills ethically and responsibly) can easily be achieved by designing a compost box and a compost heap, making them and evaluating the process. LO 2 (related to understanding and applying relevant technological knowledge) could easily be achieved in the irrigation activity, and LO 3 (related to demonstrating interrelations between science, technology, society and environment) could easily be attained in both compost making and planting. The study also showed that curriculum activities, such as those used in this study, are influenced by socio-cultural and structural factors that influence the curriculum contextualizing process. The main findings of the study are captured in five analytical statements. These form the basis for a set of recommendations to inform the use of school gardens as a resource for technology teaching in Ethridge Junior Secondary School, and possibly for other rural schools.

The study indicates that LO 1 (related to applying technological processes and skills ethically and responsibly) can easily be achieved by designing a compost box and a compost heap, making them and evaluating the process. LO 2 (related to understanding and applying relevant technological knowledge) could easily be achieved in the irrigation activity, and LO 3 (related to demonstrating interrelations between science, technology, society and environment) could easily be attained in both compost making and planting. The study also showed that curriculum activities, such as those used in this study, are influenced by socio-cultural and structural factors that influence the curriculum contextualizing process. The main findings of the study are captured in five analytical statements. These form the basis for a set of recommendations to inform the use of school gardens as a resource for technology teaching in Ethridge Junior Secondary School, and possibly for other rural schools.

- Description: Rosmarinus officinalis L. is known extensively for its multifunctional purposes. The essential oil has been widely used in cosmeceuticals and several ethnopharmacological values. In vitro studies have demonstrated the antibacterial activity of essential oils (EOs) of Rosmarinus officinalis L. against Staphylococcus aureus ATCC 25923, Vibrio cholerae DSM 19283, Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 27853 and Bacillus cereus. These different bacteria were screened against antibiotics such as Tetracycline, Ampicillin Sodium salt, Erythromycin and Amoxicillin, and some standards namely rosmarinic acid, carnosic acid and carnosol, and also against the methanol, acetone, chloroform and dichloromethane extracts of rosemary. The essential oils of Rosmarinus officinalis L. showed significant inhibitory properties compared to antibiotics with various degrees of growth inhibition. The standards exhibited some activities against the organisms. The GC/MS analysis of the essential oil revealed 34 compounds present with most components acting in synergy to bring about antibacterial activities. The antiplasmodial and cytotoxic activities of two leaf extracts of Rosmarinus officinalis (with hexane and dichloromethane as solvents) using standard procedure were studied. The findings justify the claims on the efficacy of plants for therapeutic uses for antifungal, antibacterial and anti-inflammatory properties. Antiplasmodial activity of Rosmarinus officinalis recorded IC50 values of 9.99 µg/ml and 9.76 µg/ml in hexane and dichloromethane respectively.

Microsatellite and morphometric analysis of chokka squid (Loligo reynaudi) from different spawning aggregations around the South African coast

- Description: Accurate information on stock structure is very important to the effective management of any commercially exploited species (Angel et al. 1994), particularly in annual species like Loligo reynaudi. Previous molecular work on a number of fish and cephalopod species has shown that stock structuring may be more complex than originally believed and while much scientific work has been conducted on Loligo reynaudi to date, molecular work has been lacking and this species’ fishery is currently managed as a single stock. The primary aim of this project was to examine the population genetics of Loligo reynaudi on a molecular level, by looking at the levels of genetic variation between different spawning aggregations along the inshore distribution of the chokka squid, with particular attention being paid to any variation between Eastern Cape and Agulhas Bank groups. The secondary aim was to conduct a morphological analysis on samples from the same major areas in order to see if any genetic variation observed would be complemented by phenotypic variation. Two separate sample sets were collected; Genetic samples were collected from 6 different spawning sites along the South African Coast between April and July, 2006 and whole individuals for morphometric analysis were collected from 4 spawning sites between April and July 2007. Samples were screened for genetic variation between different spawning aggregations along the inshore distribution of chokka squid, from Port Alfred in the Eastern Cape, to the western Agulhas Bank. After this a morphometric analysis on samples from the same major areas, Eastern Cape, Agulhas Bank and Angola, was carried out. Genetic results showed significant variation between some of the sample groups. As expected, the Angolan outgroup consistently showed significant variation from other samples, while there was evidence of differentiation between the South African samples themselves. These results could have implications for the previously documented life cycle model of Loligo reynaudi and provide a basis for further study at a finer resolution into where exactly the boundaries of these different groupings can be found. This stock structuring has implications for the management of the species and warrants further genetic research with microsatellites proving to be a powerful tool in the explanation of stock structuring. Unfortunately, due to possible errors in taking measurements, morphometric analysis did not yield useful results which can be described and interpreted in this study. It is felt that further genetic study conducted on a finer scale, should be accompanied by a repeat of the morphometric analysis.

- Description: The spatial and temporal (seasonal and diel) patterns in the hyperbenthic community structure (>500 μm) was investigated in the warm temperate, permanently open Kariega Estuary situated along the south-eastern coastline of South Africa. Spatial and seasonal patterns in the hyperbenthic community structure were assessed monthly at six stations along the length of the estuary over a period of twelve months. Data were collected using a modified hyperbenthic sledge, comprising two super-imposed nets. Physico-chemical data indicate the presence of a constant reverse salinity gradient, with highest salinities measured in the upper reaches and lowest at the mouth of the estuary. Strong seasonal patterns in temperature, dissolved oxygen and total chlorophyll-a (chl-a) concentrations were evident. Total average hyperbenthic densities ranged between 0.04 and 166 ind.m-3 in the lower net and between 0.12 and 225 ind.m-3 in the upper net. Hyperbenthic biomass values ranged between 0.02 and 11.9 mg.dry weight.m-3 in the lower net and between 0.02 and 17.4 mg.dry weight.m-3 in the upper net. A spatial and temporal pattern in total densities was detected with an increase in abundance over the period of September to October 2008 particularly in the middle reaches (Stations 3 and 4). Both the lower and upper nets were numerically dominated by decapods (mainly brachyuran crab zoeae) with the exception of June and July 2008 when mysids (mainly Mesopodopsis wooldridgei) dominated, making up 72.4 ± 58.14% of the total abundance in the lower net. A redundancy analysis (RDA) indicated that 99.2% of the variance in the hyperbenthic community structure could be explained by the first two canonical axes. Axis one, which accounted for 96.8% of the total variation detected in the ordination plot was highly correlated with sedimentary organic content and to a lesser extent the chl-a concentration within the Kariega Estuary. The correlations with the second canonical axis (2.4%) were less obvious, however, salinity and seston concentration were weakly correlated with this axis. Diel variability in the hyperbenthic community structure was assessed during March 2009. Samples were collected during the day and night (n = 6 for each period) using sampling gear described above. Total average hyperbenthic densities during the day (497.9 ± 254.1 ind.m-3) were significantly higher than night-time estimates (129.9 ± 38.5 ind.m-3; p<0.05). There were no significant differences in the average dayand night-time estimates of hyperbenthic biomass (p>0.05). A hierarchical cluster analysis identified two significantly distinct groupings, designated the day and night samples. Results from the SIMPER procedure indicated that the high densities of crab zoeae recorded during the day-time accounted for the majority of the dissimilarity between the day and night groupings (44.7%). In addition, it is apparent that several benthic species, especially from the cumacean and isopod orders, were absent from the hyperbenthos during the day-time and emerged into the water column at night.

- Description: In this project, nickel and metal-free 4β-(4-tert-butylphenoxy) phthalocyanine, biphenyl bridged binuclear 4-tert-butylphenoxy phthalocyanine and naphthalene bridged binuclear 4-tert-butylphenoxy phthalocyanine have been synthesised. The Z-scan technique has been employed to comparatively study their second order nonlinear optical (NLO) properties. This work, shows that the presence of H-aggregation in binuclear Pcs of metal-free and nickel 4β-(4-tertbutylphenoxy) phthalocyanines do not have an effect on the magnitude of second order nonlinear absorption coefficient (β) as compared to monomeric Pcs. Density functional (DFT) calculations of dipolar/octupolar contributions were performed, in order to explain experimentally determined β values. Spectroscopic and photophysical properties of the synthesised compounds have been determined using a range of different spectroscopic techniques, including magnetic circular dichroism (MCD), time correlated single photon counting spectroscopy (TCSPC), UV-visible absorption spectroscopy, mass spectroscopy and IR Spectroscopy.
