- Description: This book of poems ranges in style from narrative to condensed lyric moment, and shifts in perspective from observation to introspection. Thematically, these poems explore everyday life through its many manifestations – memory, nature, marriage, faith and death – with an emphasis on finding meaning in absolutely ordinary things. Though their tone is often vulnerable and tender, even when it is more distant the poems are always searching.

- Description: The aim of the study was to explore the effects of the absence of an overarching national information policy on information services in Malawi. The objectives of the study were to: find out the effects of the absence of an overarching national information policy on information access in Malawi; establish factors impeding the development of an overarching national information policy in Malawi; find out the extent to which the absence of an overarching policy has affected capacity building in information services in Malawi; and identify the legal and regulatory framework implications of the absence of such a policy in Malawi. The study adopted an exploratory research design. Data were collected using document analysis, observations and in-depth interviews. Eighty-two face-to-face interviews were conducted with policy makers in government, Members of Parliamentary committees on legal and media issues, information scientists, information service providers, academicians, legal experts and information users. Purposive sampling was used to select participants. An interview guide comprising closed and open ended questions was used to interview respondents. Data were analysed using quantitative and qualitative methods. The findings of this study may be used by Government in developing relevant national information policies that would enhance free access and utilisation of information. Furthermore the study is significant in identifying factors that may impede the development of a national information policy. The study revealed that Malawi has a brittle national information policy framework for the provision of information services. Malawi doesn’t have an overarching policy framework for the sector and as a result, there is no policy guidance to drive the development of sectoral policies and supporting legislation. Policy development in Malawi is more reactive to issues than systematic and very slow. Consequently, access to and utilization of information is low; capacity building is low in terms of competencies and infrastructure and; the legal and regulatory framework for information services is weak. The study also revealed that factors impeding the development of an overarching national information policy include: motivation for the development of sectoral information policies; lack of an institutional framework to guide the development of policy; lack of finances and technical capacity; lack of sustained political will; level of economic development; existence of overarching government development plans; international trends; and the diverse nature of the information sector. The general recommendation emanating from the findings of the study is that Malawi needs an overarching national information policy which would articulate and address issues regarding access to information, capacity building in terms of skills and infrastructure, and the legal and regulatory framework. Information is a cross-cutting issue requiring an all-encompassing policy. However, specific recommendations from the findings of this study are that government should expedite the development of policies and enactment of relevant pieces of legislation which are not yet in place to enhance free access and utilisation of information and ICTs; government should speed up the introduction of information literacy in the school curriculum starting from primary school level to university; government should develop a library policy to promote the development of school libraries in both primary and secondary schools, and public libraries in all towns, district assemblies and rural growth centres which should be well resourced including Internet facilities; and government should constantly review and harmonise policies and legislation in the information sector so that they are in line with current trends.

- Description: The majority of South African public schools are not performing well considering the overall learner success rates in specifically so called disadvantaged schools. Many factors contribute to this situation, however, all education stakeholders contribute in some way to the success or failure of schools. In this regard alumni of disadvantaged schools in South Africa have not played an active role in supporting their alma maters. This research sought to identify the various roles alumni can play in the development of disadvantaged schools. As innovative strategies to the public education crisis in South Africa are required, one such strategy is to involve a neglected stakeholder group such as alumni to share their skills and resources towards improving the different aspects of school development. There are very few examples of functioning alumni associations at previously disadvantaged schools in the Eastern Cape. Sharing information on a study of two selected schools with already established alumni associations could be of value to other schools in the establishment of their own alumni associations in order to support school improvement and development initiatives. Therefore, based on the findings of this study and from evidence in literature, the researcher concludes that alumni associations can play a meaningful role in developing and transforming disadvantaged schools in a young and developing democracy as in the case of South Africa. This study looked at, amongst other aspects, at the roles and contributions that alumni may play in the development of their alma maters and finally offer guidelines in the establishment of alumni associations.

- Description: When the Arab Spring took place, it took the world by surprise and sparked renewed interest in the idea of revolution. With differing opinions on what caused such a revolutionary wave throughout the North African and Middle Eastern region, many began looking at their own countries, and South Africa was no different. A debate was sparked in South Africa, as to whether there would be a revolution or not. What I originally set out to accomplish is to find out which side of the debate would be correct through the philosophical context of revolutionary theory. Initially, we attempted to define and consider the history of revolutionary theory. We found that revolutionary theory has gone through four generation and that even finding a theoretically informed definition is difficult. Following this, we considered some social-psychological theories of revolution as well as theories of moral indignation. We found that these theories were incredibly informative and that they provide some insight into the reasoning for revolutionary fear in the South African debate. Through the use of opinion pieces, we then considered the South African debate, and – using socialpsychological theories and the theories of moral indignation - found that both sides of the argument had valuable points, however, they often lacked some foresight. With tentative agreement, we found that the side arguing that there would a revolution in South Africa had a more valuable argument, despite its limitations. However, far more research is required before one can – with more accuracy – predict a revolutionary occurrence in such a way as was done in South Africa.

- Description: It is critical in this dynamic and changing environment that both the leadership and educators of schools and organisations are well equipped with the skills and knowledge to create high performance teams (HPT). High performance teams can be defined as those highly motivated team players in the organisation or school that maximise their people integrated knowledge, skills and values to a shared purpose or vision of their stakeholders. In this mixed method research an analysis of the whole school operational teams of some secondary schools including all educators, head of departments, administrators and principals was undertaken. Four secondary schools from two quintile groups situated in various areas of the Nelson Mandela Bay Metropolitan were the sampling units and the sample size was eighty one. Both quantitative and qualitative data was collected utilising a carefully constructed questionnaire based on a theoretical conceptual framework of enabling factors for HPT in business contexts. The theoretical framework of the Kenexa High Performance Model was utilised in this study. A questionnaire was constructed based on the factors of the High Performance Work Index (HPW) study done by the Australian Business School. This model was adjusted to utilise factors aligned to those factors within the school operational context. Using other literature references further factors were included into the survey instrument. The School High Performance Work Index (SHPWI) was the dependent variable while the independent variables included organizational commitment, and employee engagement. These were literature based measures and the questionnaire items were taken from previous research studies, thereby allowing construct validity. The other independent variables included Communication, Leadership, Strategic Management, School Organizational Climate, Positive Practices, Conflict Management, Motivation and Trust. A statistical analysis was undertaken on each school’s team response data. Reliability and validity of the constructed questionnaire was shown by using the Kenexa employee engagement index and the Organizational Commitment measure, which were highly correlated with the SHPWI. In literature, high performance teams (HPT) show common patterns in business and in this study it was seen that a number of common factors contributed towards a HPT in school operational teams. In this research study the main enabling factors in whole school operational teams that could lead to the formation of HPT’s involved factors of leadership, communication and motivation. The SHPWI showed a high correlation with employee engagement and organizational commitment. The HPT profile involved innovation (freedom of thinking), employee (educator) engagement, fairness, leadership, learner needs, communication, trust, conflict management, school organizational climate, positive practices, strategic management and motivation. In the correlation between the SHPWI and the independent variables the highest correlation (statistically significant at p < 0.05 N = 81; r > 0. 500) occurred between the School High Performance Index and Leadership (0.822), Communication (0.785) and Motivation (0.766). In the multiple linear regression (MLR) of the results of this study the highest correlations with a value of R2 = 0.774 was obtained with variables of Leadership, Communication, Motivation and Strategic Management factors. Qualitative data was coded and linked with the factors in the quantitative data and the top five factors were selected and summarised for each school. Merged data showed that each school exhibited a different profile of strengths and weaknesses. Recommendations were outlined for each school operational team. Different schools in different quintiles have different needs and gap factors that require improvement. It is therefore imperative that schools analyse their strengths and weaknesses within their school operational teams. This research study aimed therefore to start research on a human resource metric that can be further developed to allow school operational teams to examine and analyze their own HPT profile, so that specific interventions may be implemented.

- Description: Adventure tourism (AT), defined as “a broad spectrum of outdoor touristic activities,often commercialized and involving an interaction with the natural environment away from the participants’ home range and containing elements of risk,” (Hall, 1992, p. 143) is currently one of the fastest growing sub-sectors of the tourism industry (Buckley 2010). Because it has emerged relatively recently as a field of study, a number of scholars have called for ongoing research in the area, see Swarbrooke (2003), Pomfret (2006), Buckley (2010), Rogerson (2007), and Williams & Soutar (2005). Much of this research, to date, has focused on marketing, injury caused by AT participation, environmental impacts, and the broad notion of “risk” associated with AT. The problem is that little of this work has focused on the significance of the environment in adventure tourism – an important element inherent in its definition. Thus, this thesis aims to move beyond a general risk-based analysis of AT, and focus on the role of the environment. This is done through a human-environment interaction approach undertaken in Tsitsikamma Village where five adventure tourist operations are based. The first step in operationalizing this approach was to develop a conceptual framework that integrated adventure tourism into a general framework on humanenvironment interaction. The second step was to use a research instrument which enabled one to examine the influence of the environment on human motivations and adventure tourism experiences, and not only the influence of humans on the environment. The former was accomplished through questionnaires based on external, environmental elements that attract adventure tourists as well as inherent personality traits impel such tourists to participate in AT. The latter, based on interviews and participant perceptions, sought to establish the significance of impacts on the environment as well as initiatives taken by AT companies to minimize environmental damage. The findings show that although risk/thrill does play a role, AT motivations and experiences are complex and multidimensional. The environment does significantly influence both motivations and even more so AT experiences. Furthermore, there are distinct differences between the motivations and experiences of participants in different types of AT activities, indicating that generalizing the industry as whole neglects these significant differences. In terms of influences on the environment, the results show that most AT operators in the Tsitsikamma have some consideration for environmental protection and take some initiatives to minimize environmental damage, though the degree to which this occurs differs significantly. Furthermore, activity participants do not believe that the activities have a strong negative impact on the environment, though the majority acknowledge small impacts. The types of impacts observed by participants vary significantly between companies. This thesis demonstrates the manner in which the two-way relationship between humans and the environment manifests itself in the commercial AT industry. The result is a well-rounded examination of the influence of human-environment interaction on AT participants.

- Description: South Africa and other developing countries are grappling with high levels of poverty as a result of slow to negligible rural development. Irrigation development is one essential component that can be used to address the challenges faced by smallholder farmers in rural areas. In the President‟s “State of the Nation Address” in 2011, the President of South Africa outlined measures to reduce hunger and poverty in communal areas through enhanced government‟s expenditures in rural infrastructure developments, especially for such amenities as irrigation and roads, with a view to promoting food security. The broad objective of this study is to assess livelihood strategies and opportunities with regard to farming in Qamata area of Intsika Yethu Local Municipality. The stratified random sampling method was applied in order to choose a sample of 70 household that were interviewed by means of semi-structured questionnaires. Out of these, 53 belonged to the irrigation project and 17 farmers were non-irrigation farmers. The results show that women play an active role in agriculture. The Multiple Regression model was used to assess the relative importance of different livelihood strategies adopted by both irrigation and non-irrigation farmers in improving household food security and welfare in Qamata. More specifically, the study assessed the impact of different livelihood strategies on production of butternut, goats, maize and poultry (Chicken) in Qamata. The results show increased agricultural production, crop diversification and higher incomes from irrigation farming as compared to dry land farming. Irrigation farming has enabled many households to diversify their sources of income and therefore include activities and enterprises that contribute to enhanced household welfare. The study showed that household size is crucial in crop production, followed by gender of the household head. The government and research institutes need to come up with programmes to train people on ways to produce crop and livestock products more efficiently.

The broad objective of this study is to assess livelihood strategies and opportunities with regard to farming in Qamata area of Intsika Yethu Local Municipality. The stratified random sampling method was applied in order to choose a sample of 70 household that were interviewed by means of semi-structured questionnaires. Out of these, 53 belonged to the irrigation project and 17 farmers were non-irrigation farmers. The results show that women play an active role in agriculture. The Multiple Regression model was used to assess the relative importance of different livelihood strategies adopted by both irrigation and non-irrigation farmers in improving household food security and welfare in Qamata. More specifically, the study assessed the impact of different livelihood strategies on production of butternut, goats, maize and poultry (Chicken) in Qamata. The results show increased agricultural production, crop diversification and higher incomes from irrigation farming as compared to dry land farming. Irrigation farming has enabled many households to diversify their sources of income and therefore include activities and enterprises that contribute to enhanced household welfare. The study showed that household size is crucial in crop production, followed by gender of the household head. The government and research institutes need to come up with programmes to train people on ways to produce crop and livestock products more efficiently.

- Description: Background: The National Department of Health realised that its TB control efforts had been ineffective and joined its international counterparts by adopting Directly Observed Treatment short course [DOTs] strategy to fight the spread of TB. DOT is the only globally recognised strategy for effective TB control. This strategy ensures that infectious TB patients are identified and cured using standardised drug combinations. Treatment supporters observe patients as they swallow their drugs daily (SA Tuberculosis control Programme practical guide, 2000). Objectives of the study are: to assess the relevancy and quality of training for DOT supporters at InxubaYethemba and Tsolwana sub – districts,to identify challenges faced by TB DOT supporters during the execution of their duties and to assess satisfaction of TB DOT supporters, with their remuneration packages and other conditions of employment. Method: A quantitative descriptive convenient design was conducted for this study. A self - administered questionnaire was used.The researcher’s targeted sample was 42 participants although only 39 filled in the questionnaires. The questionnaires were personally distributed by the researcher to TB DOT supporters. Items in the questionnaire included the following: Demographic data, working hours per day, distance covered, meeting with managers, salary and remuneration issues and acceptance by community members. Results: The research findings indicated that the TB DOT Supporters are generally not happy with the conditions they are working under. From the 100 percent (n=39) TB DOTS responses, 8 percent (n=11) received a three days training, which is not in line with the Department of Health’s guidelines, and resulted in rendering ineffective delivery of DOT programme. Of the 100 percent ) 23.1 percent (n=9) walk 8kilometres, 51.3 percent percent(n=20) walk 7kilometers, 12.8 percent (n=5) walk 5kilometers, 10.3 percent (n=4) walk 4kilometers. This is against the required distance allowed to travel by foot which is five kilometres. Conclusion:According the results of this study, the effectiveness of TB DOT Supporters is being distracted by many factors, such as: Not having transport for doing home visits, Less number of hours worked per day, few number of community health workers working as TB DOT supporters, not having meetings with the management to discuss their challenges, and most of all not being given a clear explanation as far as their salaries are concern. The mentioned factors render D OT Support programme is rendered in effective at the Chris Hani District. According to Tuberculosis, A training Manual proven for Health Workers (1998:13) the most effective means of controlling TB known to us is a strategy known as Directly Observed Treatment Short Course (DOTS). This strategy enables tuberculosis clients to complete their treatment and has four areas of strength when compared to previous TB control strategies in South Africa. Recommendation: The results from this study proves that there is a definite need for improvement of working condition amongst TB Co-ordinators, TB Managers and the TB DOT Supporters. It is clear that increased number of MDR/XDR is due to the challenges that were mentioned above. There is a need for the additional number of TB DOT Supporters, as the area is big for only two TB DOT Supporters in each area. Hours worked by TB DOT needs to be extended considering their salaries as well.Therefore it is essential to empower TB DOT Supporters with more knowledge and skills so that they can be able to make an impact in TB service delivery system.

- Description: This paper is divided into two distinct sections. The first being an analysis of the legal protection of temporary employees as things currently stand. It deals with the various labour laws that currently regulate temporary employment as well as the temporary employment contract and the common-law. The second section summarises and analyses the provisions of the Labour Relations Amendment Bill and the Basic Conditions of Employment Bill as they apply to fixed-term employees. Temporary employees are protected by the general protection extended to all employees in terms of section 23(1) of the Constitution of the Republic of South Africa, 1996, guaranteeing all employees the “right to fair labour practice”. The Labour Relations Act has as one of its main objectives to give effect to and regulate the fundamental rights contained in the Constitution. Thus the Labour Relations Act must not only give effect to constitutional rights but it must also ensure that it in no way unreasonably or unjustly denies or limits constitutional rights. Temporary employees have a number of labour laws protecting their interests. Where the provisions of the Basic Conditions of Employment Act, a Bargaining Council Agreement or a Sectoral Determination do not apply the employee will rely on the terms of the fixed-term employment contract and thereafter the common law for protection. The only protection offered to temporary employees contained in the Labour Relations Act is in section 186(1)(b), where a dismissal is defined to include the non-renewal of temporary contracts of employment where there is a reasonable expectation of renewal on the same or similar terms. This provision has proved to be highly controversial in that it does not expressly cater for temporary employees who harbour reasonable expectations of indefinite employment. An analysis is made of the most important cases relating to section 186(1)(b). The second section unpacks and critically analyses the Labour Relations Amendment Bill and the Basic Conditions of Employment Bill which have been long in the offing and when they are finally enacted, will bring with them sweeping changes for atypical employment . The amendments will drastically change the way employers make use of fixed-term employees as well as the way in which Temporary Employment Services may conduct business if they are in fact able to keep working at all. There is very little literature of substance written about the Labour Relations Amendment Bill as it applies to atypical employment. The fact that the proposed amendments have changed so many times over such a long period of time might have deterred many writers from investing time and effort in attempts to analyse and summarise the amendments. Articles posted on the internet are in the main short and have very little content. No books were found with any discussion that pertains to the amendments. The amendments divide employees involved in atypical employment into two different categories. These categories consist of employees earning above the threshold in terms of section 6(3) of the Basic Conditions of Employment Act and those earning below this threshold. All fixed-term employees may rely on the provisions of section 186 of the Labour Relations Act. Employees earning below the threshold are considered to be the most vulnerable and have been afforded additional protections in terms of sections 198(A), (B) and (C).

- Description: Even though the post-apartheid democratic government introduced a “social model” approach to address disability, there is still low employment rate of People with Disabilities. Government has enacted different legislation aimed at the inclusion of people with disabilities into the mainstream of society; however, the majority of people with disabilities are unemployed and often denied employment opportunities. The study seeks to evaluate employment of people with disabilities, identify challenges facing the government departments and local municipalities in employing people with disabilities, and to determine what measures can be taken to improve the employment of this group. A purposive sampling was used to select the government departments and the municipalities. A total of seven organisations, participated in the study consisting of four government departments and three local municipalities of the Joe Gabi District. During the interviews, a semi-structured interview guide was used to generate in-depth interpretation from the participants. The data was then analysed using quantitative methods such as graphs and tables and qualitative methods such as data coding through Tech's (1990) framework as described in (Creswell, 2003). The findings of the research revealed that government departments and municipalities still experience challenges in recruiting and providing employment opportunities to people with disabilities. There are a number of factors perceived by participants as challenges to low recruitment and employment of people with disabilities. These include: A lack of clear internal policies and guidelines at district levels of the government departments; Tendency by the government departments and municipalities to use the Employment Equity Plans only as a tool for compliance with legislation; A lack of effective recruitment strategies especially for people with disabilities. The participants also suggested a number of ways to improve employment and recruitment of people with disabilities, which include partnering with relevant organisations that could help in providing work-seekers who are persons with disability, developing effective internal recruitment strategies, HR managers to be trained in disability management and all relevant legislation and finally departments to fund posts specifically for people with disabilities.

- Description: The purpose of the study was to explore and describe the strategies used by nurses to implement the national treatment guidelines to prevent, detect and manage multi-drug resistant tuberculosis (MDR-TB) patients. Tuberculosis remains one of the leading infectious diseases and the major cause of death worldwide with estimates of 9.2 million new TB cases in 2008 and 1.7 deaths including 200 000 in clients co-infected with HIV. South Africa is currently ranked 3rd among the 22 high TB burden countries in the world. The HIV/AIDS epidemic contributes significantly to the upward trend in TB morbidity and it is estimated that more than 50% of TB patients are also HIV positive (South African Department of Health 2009:10). The current rate of tuberculosis infections as a result of new infections as well as re-infections of patients is of concern to the disease control and policy making bodies of South Africa. Questions regarding the effectiveness of tuberculosis policies and programmes emerge at all times (Luhulima, Netshandama and Davhana-Maselesele, 2008: 36). Patients with multidrug-resistant (MDR) tuberculosis (TB) are at high risk of treatment failure. It is anticipated that early identification of MDR-TB and appropriate treatment will improve patient outcome and disease control. This study intends to explore the effectiveness of health systems in the prompt identification and management of MDR patients. This study was conducted using a qualitative, explorative and descriptive design. A purposive sample of clinics and professional nurses was selected, and voluntary participation was ensured. The data was collected through individual interviews which were audio taped and then transcribed verbatim. Findings revealed that MDR-TB guidelines were available at the clinics. The professional nurses implemented the guidelines to prevent, detect and manage multi-drug resistant tuberculosis, by screening and testing symptomatic high risk groups, contact tracing and monitoring, providing initial counselling and education to patients and family, preparing patients for admission when indicated and coordinating referrals to the centralised MDR-TB unit. However, there were notable constraints with regards to the management of MDR-TB patients and the overall TB programme. These included MDR-TB specific training, staff shortages, dysfunctional community DOT programme, shortage of beds at the MDR-TB treatment centres, and patient factors like defaulting, migration for various reasons, alcoholism. All these constraints call for intensified strategic management at both policy and facility level. It is also necessary that all policies related to patient management need extensive scientific study to monitor and evaluate their effectiveness. More research studies are required on policy analysis and utilization.

The first is that court decisions (especially those in which a written judgment is handed down) need to be clearly reasoned and logically articulated to be understandable, effective and to have value in a system of precedent that finds its ultimate lodestar in the rule of law. There is no constitutional or statutory requirement that a court in all cases must furnish reasons, or even written reasons, for its decision But the practice of doing so, the Constitutional Court has said, supports the rule of law, ensuring that judicial decision-making does not occur in a manner that is arbitrary, and ensures that judges may be held accountable for their decisions. The second requirement is a technical rule – the rule of majority: if the case is heard by a full bench, and where differing opinions are handed down by the judges hearing the case, the ratio decidendi can only be identified from those judges whose reasoning is in the majority.

- Description: Education institutions globally are increasingly expected to explore avenues for the implementation of service-learning into their curricula. A second-year undergraduate organic chemistry laboratory experiment, in which the undergraduate students make azo dyes, can provide a vehicle for a service-learning module in which university undergraduate students then teach students from resource-limited secondary schools how to make azo dyes. Evidence is provided to show how the theory is reinforced for both sets of students through a shared practical experience. The practical application of chemistry is conveyed through the use of the synthetic azo dyes to dye tshirts. The results of this study show that the service-learning experience clearly assists undergraduate students to appreciate the role of chemists in the broader society while at the same time increasing awareness of the inequalities in school education systems.

- Description: The purpose of this research was to investigate strategies employed by primary teachers to support the non-isiXhosa speaking learners of Mthatha Education District. This was the researcher’s observation and concern emanating from the difficulties displayed by her non-isiXhosa speaking learners, as the medium of instruction in these schools is not their mother tongue. The language of learning and teaching (LOLT) is isiXhosa in the school where the research was conducted. The school is composed of non-isiXhosa speaking and isiXhosa speaking learners. The research sought to address the following questions: 1 What strategies are employed by Mthatha district teachers to support non- isiXhosa speaking learners? 2 What challenges do Mthatha teachers face in supporting the non-isiXhosa speaking learners? 3 How do Mthatha teachers overcome the challenges they face in supporting the non-isiXhosa speaking learners? The qualitative design approach was used in this study. The study was a case study of one Mthatha primary school. Face-to-face interviews were used to collect the data from the six female teachers who teach from Grade 1 to Grade 6 and one male teacher who is the principal of the selected school, and who teaches English and Life Orientation from Grade 7 to Grade 9. The interviews were tape-recorded. The data collection process began after all the ethical consideration requirements were fulfilled and approved by the relevant stakeholders of the research. The thematic approach was adopted as data analysis of the study was guided by the responses given to the questions asked of interviewed teachers. The research showed the following results which surfaced from the data provided by the respondents: (i) Teachers employed few teaching strategies to support the non-isiXhosa speaking learners in their multilingual classroom. The interviewed teachers expressed their challenges as stemming from the large numbers of learners in their classrooms; (ii) IsiXhosa as a language of learning and teaching was a challenge for the non-isiXhosa speaking learners. (iii) Absenteeism and indiscipline by non-isiXhosa speaking learners (iv) Limited or non-involvement of parents in the education of children The data also showed that there was limited support to empower teachers to deal with multilingual classrooms. The study made the following and other recommendations based on the results: teachers should use many teaching strategies in linguistically diverse classrooms. The school management teams (SMTs) should admit learners in relation to the number of teachers available in a school. It is also recommended that schools implement the language policy as it relates to the learners in each classroom. The DoE should increase parental involvement in the education of their children and also provide professional support to teachers.

- Description: Despite extensive research into the effects of alcohol consumption, there is no clear understanding into the mechanisms underlying human information processing impairment. The acute consumption of alcohol was investigated to determine the implications for human information processing capabilities, and to identify the extent to which these implications were stage-specific. Further aims included the investigation and quantification of caffeine-induced antagonism of alcohol impairment. Moreover, the aforementioned relationships were investigated in morning versus evening conditions. A test battery of six resource-specific tasks was utilised to measure visual perceptual, cognitive and sensory-motor performance, fashioned to return both simple and complex measures of each task. The tasks implemented were: visual perceptual performance (accommodation, visual detection, visual pattern recognition); cognition (memory recall- digit span); and motor output (modified Fitts‟ and a driving simulated line-tracking). Performance measures were recorded by the respective computer based tasks. Physiological variables measured included heart rate frequency, heart rate variability (RMSSD, High and Low Frequency Power) and body temperature. Saccade speed, saccade amplitude, pupil size and fixation duration were the oculomotor parameters measured. Three groups of participants (alcohol, caffeine+alcohol and control) n=36 were studied, split evenly between sexes in a mixed repeated/non-repeated measures design. The control group performed all test batteries under no influence. The alcohol group performed test batteries one and two sober, and three and four under the influence of a 0.4 g/kg dose of alcohol. Group caffeine+alcohol conducted test battery one sober, two under the effect of caffeine only (4 mg/kg), and three and four under the influence of both caffeine and alcohol (0.4 g/kg). The third test battery demonstrated the effects of alcohol during the inclining phase of the blood alcohol curve, and the fourth represented the declining phase. Morning experimentation occurred between 10:00 - 12: 45 and 10:30 -13:15 with evening experimentation between 19:00 - 21:30 and 19:30 - 22:00. Acute alcohol consumption at a dose of approximately 0.4 g/kg body weight effected an average peak breath alcohol concentration of 0.062 % and 0.059 % for the alcohol and caffeine+alcohol groups respectively. Task-related visual perceptual performance demonstrated significant decrements for simple reaction time, choice reaction time and error rate. Cognitive performance demonstrated no significant performance decrements, while motor performance indicated significant decrements in target accuracy only. Physiological parameters in response to alcohol consumption showed significantly decreased heart rate variability (RMSSD) in the modified Fitts‟ task only. A significant decrease in saccade amplitude in the memory task was the only change in oculomotor parameters. Prior caffeine consumption demonstrated limited antagonism to task-related alcohol impairment, significantly improving performance only in reduced error rate while reading. Caffeine consumption showed stimulating effects on physiological parameters, significantly increasing heart rate and heart rate variability when compared to alcohol alone. The design of the tasks allows for comparison between complex and simple task performance, indicating resource utilisation and depletion. Complex tasks demonstrated higher resource utilisation, however with no statistical performance differences to simple tasks. Physiological parameters showed greater change in response to alcohol consumption, than did the performance measures. Alcohol consumption imposed significant changes in physiological and oculomotor parameters for cognitive tasks only, significantly increasing heart rate frequency and decreasing heart rate variability, skin temperature and saccade amplitude. Caffeine consumption showed no antagonism of alcohol-induced performance measures. Physiological measures showed that caffeine consumption imposed stimulating effects in only the neural reflex and memory tasks, significantly increasing heart rate frequency and heart rate variability. Prior caffeine consumption significantly decreased fixation duration in the memory task only. The time of day at which alcohol was consumed demonstrated significant performance and physiological implications. Results indicated that morning consumption of alcohol imposes greater decrements in performance and larger fluctuations in physiological parameters than the decrements in evening experimental sessions. It can be concluded that alcohol consumption at a dose of 0.4 g/kg affects all stages in the information processing chain. Task performance indicates that alcohol has a greater severity on the early stages of information processing. Conversely, under the influence of alcohol an increased task complexity induces greater effects on central stage information processing. In addition, caffeine consumption at a dose of 4 mg/kg prior to alcohol does not antagonise the alcohol-induced performance decrements.

- Description: In the KwaZulu-Natal (KZN) Midlands North region of South Africa, the importance and increased prevalence of endemic scarabaeids, particularly Hypopholis sommeri Burmeister and Schizonycha affinis Boheman (Coleoptera: Melolonthinae), as soil pests of sugarcane, and a need for their control was established. The development of a mycoinsecticide offers an environmentally friendly alternative to chemical insecticides. The identification of a diversity of white grub species, in two Scarabaeidae subfamilies, representing seven genera were collected in sugarcane as a pest complex. Hypopholis sommeri and S. affinis were the most prevalent species. The increased seasonal abundances, diversity and highly aggregated nature of these scarabaeid species in summer months, suggested that targeting and control strategies for these pests should be considered in this season. Increased rainfall, relative humidity and soil temperatures were linked to the increased occurrence of scarab adults and neonate grubs. Beauveria brongniartii (Saccardo) Petch epizootics were recorded at two sites in the KZN Midlands North on H. sommeri. Seventeen different fluorescently-labelled microsatellite PCR primers were used to target 78 isolates of Beauveria sp. DNA. Microsatellite data resolved two distinct clusters of Beauveria isolates which represented the Beauveria bassiana senso stricto (Balsamo) Vuillemin and B. brongniartii species groups. These groupings were supported by two gene regions, the nuclear ribosomal Internal Transcribed Spacer (ITS) and the nuclear B locus (Bloc) gene of which 23 exemplar Beauveria isolates were represented and sequenced. When microsatellite data were analysed, 26 haplotypes among 58 isolates of B. brongniartii were distinguished. Relatively low levels of genetic diversity were detected in B. brongniartii and isolates were shown to be closely related. There was no genetic differentiation between the two sites, Harden Heights and Canema in the KZN Midlands North. High gene flow from swarming H. sommeri beetles is the proposed mechanism for this lack of genetic differentiation between populations. Microsatellite analyses also showed that B. brongniartii conidia were being cycled from arboreal to subterranean habitats in the environment by H. sommeri beetles. This was the first record of this species of fungus causing epizootics on the larvae and adults of H. sommeri in South Africa. The virulence of 21 isolates of Beauveria brongniartii and two isolates of B. bassiana were evaluated against the adults and larvae of S. affinis and the adults of H. sommeri and Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae). Despite being closely-related, B. brongniartii isolates varied significantly in their virulence towards different hosts and highlighted the host specific nature of B. brongniartii towards S. affinis when compared to B. bassiana. Adults of S. affinis were significantly more susceptible to B. brongniartii isolates than the second (L2) or third instar (L3) grubs. The median lethal time (LT₅₀) of the most virulent B. brongniartii isolate (C13) against S. affinis adults was 7.8 days and probit analysis estimated a median lethal concentration (LC₅₀) of 4.4×10⁷ conidia/ml⁻¹. When L2 grubs were treated with a concentration of 1.0×10⁸ conidia/ml⁻¹, B. brongniartii isolates HHWG1, HHB39A and C17 caused mortality in L2 grubs within 18.4-19.8 days (LT₅₀). Beauveria brongniartii isolate HHWG1 was tested against the L3 grubs of S. affinis at four different concentrations. At the lowest concentration (1×10⁶ conidia/ml⁻¹), the LT₅₀ was 25.8 days, and at the highest concentration (1×10⁹ conidia/ml⁻¹) the LT₅₀ dropped to 15.1 days. The persistence of B. bassiana isolate 4222 formulated on rice and wheat bran and buried at eight field sites in the KZN Midlands North was evaluated by plating out a suspension of treated soil onto a selective medium. All eight field sites showed a significant decline in B. bassiana CFUs per gram of soil over time, with few conidia still present in the samples after a year. Greater declines in CFUs were observed at some sites but there were no significant differences observed in the persistence of conidia formulated on rice or wheat bran as carriers. Overall, poor persistence of B. bassiana isolate 4222 was attributed to suboptimum temperatures, rainfall, which rapidly degraded the nutritive carriers, attenuated fungal genotype and the action of antagonistic soil microbes. Growers’ perceptions of white grubs as pests and the feasibility of a mycoinsecticide market were evaluated by means of a semi-structured questionnaire. The study showed that the reduced feasibility of application, general lack of potential demand for a product, high cost factors and most importantly, the lack of pest perception, were factors which would negatively affect the adoption of a granular mycoinsecticide. Growers however exhibited a positive attitude towards mycoinsecticides, and showed all the relevant attributes for successful technology adoption. It is recommended that because B. brongniartii epizootics were recorded on target pests which indicated good host specificity, dispersal ability and persistence of the fungus in the intended environment of application; that a mycoinsecticide based on this fungal species be developed. What will likely increase adoption and success of a mycoinsecticide is collaboration between various industries partners to increases market potential in other crops such as Acacia mearnsii De Wild (Fabales: Fabaceae).

This transformation entails a shift from an anti-communist orientation, to an anti-Islamic orientation, and while this shift has been alluded to by several theorists, in what follows it will be dealt with more systematically. In this regard, it will be traced from its roots, in the tension between modernisation theory – as espoused by figures such as Daniel Lerner – and the anti-modernisation theory of Iranian scholars such as Ahmad Fardid, Jalal al-e Ahmad and Ali Shari’ati. Following this, the development of the anti-Islamic orientation of the fifth news filter, in the wake of the Islamic Revolution in Iran, and the ensuing Iranian hostage crisis, will be explored. This will be done as a precursor to examining the continued reflection of the related tropes and stereotypes in US mainstream film, with particular focus falling on Ben Affleck’s Argo (2012). Finally, this dissertation will conclude with a consideration of the possible effects of such representations on the tensions between the US and Iran over the latter’s nuclear ambitions.

- Description: The importance of the financial structure system, which comprises the banking sector and financial markets, to the growth of a country’s economy cannot be underestimated. It is important to analyse comparatively the contribution of each sector to the economic growth of a country. This study, therefore, empirically examined the relationship between financial markets, banks and economic growth in South Africa using time series analysis for the period 1990 to 2011. The study used the Vector Error Correction model (VECM) based causality tests to establish the link between financial structure (represented by both banks and financial markets) and economic growth. Real GDP was used as a measure for economic growth, Bank credit to the private sector was used as a proxy for the banking system, turnover ratio and value of shares traded was used as a measure for the stock market and bond market capitalisation was used as a measure for the bond market. To determine the net effects of financial structure on long run growth in South Africa, one control variable was added which was the ratio of government expenditure to GDP to control for the government’s role in the economy. The Johansen co-integration technique was also employed to obtain a long run relationship. The results from the study revealed that the stock turnover ratio, bond market capitalisation, and government expenditure have a long run relationship with economic growth while bank credit to private sector and value of shares traded showed a negative relationship with economic growth. With granger causality all the variables proved to granger cause economic growth except for bond market capitalisation where economic growth prove to granger cause bond market development. The study recommended that measures to improve liquidity, transparency and accessibility of both the banking sector and financial markets instruments should be a priority for South African authorities. The authorities should, therefore, encourage stock market development through an appropriate mix of taxes, legal and regulatory policies to remove barriers to stock market operations and thus enhance their efficiency since stock markets in Africa are underdeveloped. Strong financial regulation and supervision in banks to ensure efficiency in credit allocation should be done to enable channelling of credits to capital development rather than consumption spending.

- Description: One of the serious problems facing South Africa is that of the provision of adequate low-cost housing for the poorest of poor. Only about 56% lived in fully-owned formal dwellings in 2009. (Stats SA: 2009). The problem is not only about the inability of the government to decrease backlogs in the provision of adequate low-cost houses. These contributory factors include the standard of construction, land as well as continuous urbanisation. International commitments such as the UN’s Millennium Goals put further pressure on government to permanently resolve the issue. Adequate housing is recognised globally as a basic human right. This includes access to running water and sanitation and electricity. The aim of the study is not to investigate construction techniques or methods, specific choices of location or any other planning-related issues, but to find an approach that is more appealing to the challenge of the provision of housing as per the afore-mentioned challenges combined with, amongst others, the provision of the necessary resources and relevant political processes as well as monitoring and evaluation. The provision of low-cost housing is unique in nature as it can never be fully resolved. To assist the process because of its nature, future studies suggest systems theory as a best recognised and more successful way to address wicked problems. By investigating low-cost housing programmes in Chile and Australia, identifying the elements of systems theory used, it was possible to find pointers to help formulate a set of steps (or actions) to use to address South Africa’s low-cost housing challenge. This research report proposes that, while the challenge of housing provision in a country like South Africa will most probably always be present, it can be alleviated by applying systems thinking to the problem. The study therefore puts forth Participatory Housing Delivery Monitoring Model (PHDMM). The model will assist in providing the beneficiaries of low-cost houses space to participate in the housing process and projects. It will also necessitate accountability by various participants in housing development. Capacity building will also be part of the package.
