- Description: Trafficking in human beings is a major problem worldwide. Human trafficking is as a result of a complex set of interrelated push and pull factors. Push factors includeinter alia poverty, a lack of opportunities, dislocation of families, gender, racial and ethnic inequalities and the break-up of families. Research shows that pull factors include the promise of a better life, consumer aspirations and lack of information on the risks involved, established patterns of migration, porous borders and fewer constraints on travel. It is as a result of the global epidemic of this trafficking in persons that certain instruments on an international level as well as legislation on a national level have been enacted. The question which arises is: are these pieces of legislation effective in dealing with the scourge of human trafficking? Every legislation passed will have its strengths, as well as weaknesses but the main objective of such legislation should always be to combat, criminalise and prosecute the specific criminal act. Furthermore, the enacted legislation should be designed to effectively combat the challenges which threaten to exacerbate the criminal act. Failing to fulfil this intention will render such legislation nugatory. This treatise will be looking at various international instruments that have been passed abd v adopted by various countries, which specifically deal with trafficking in humans generally and specifically in relation to the children. International instruments that will be discussed include inter alia, slavery Convention, Convention on the Rights of the child, Worst forms or Child Labour Convention, Parlemo Protocol, United Nations Transnational Organised Crime Protocol to mention but a few. All these instruments have in a way dealt with and made provisions for the criminalisation of the act of trafficking in humans and a the scrounge of trafficking escalates the international governments strive to enact instruments that are going to be able to curtail this pandemic of trafficking. As more focus will be on the South African legislation this treatise is also going to examine all the relevant piece of legislation that have been passed by the South African government in order to deal with human trafficking. These will include the discussion of the Constitution, Child Care Act, Children’s Act, Children’s Amendment Act, Criminal Law (Sexual Offences) and Related matters. Amendment Act Prevention of Organised Crime Act as well as the Prevention and combating of Trafficking in Persons Bill. The treatise will listen critically discuss the Bill in so far as its strengths and weaknesses are concerned.

- Description: Despite extensive research into shift work, workers working under rotating shift conditions are still plagued by the effects of the desynchronisation resulting from working against their natural circadian rhythms. Additionally, modern industries are shifting towards tasks requiring greater cognitive demand with less manual labour incorporated into the tasks. Research into operator based tasks, and hence those of a sedentary cognitive base both during day and night shifts, has been focusing on the effectiveness of the standard rest/break schedule. Research indicating that the standard rest break schedule is often ineffective in eliminating operator discomfort and performance deterioration, with these affects argued to be more pronounced during a night shift schedule. Therefore current research set out to investigate alternative rest break schedules, incorporating a short bout of physical activity and stretching exercises which are proposed to enhance performance and subjective mood, while eliminating operator discomfort for sedentary based cognitive tasks. Three conditions were tested during a three day habituation shift cycle within a laboratory, incorporating two night shift groups (control and experimental) and a control day shift group. Twelve subjects made up each group, with the two night shift groups completing the shift schedule together. The control groups followed a typical 8 hour shift schedule while the experimental group performed a booster break (exercise and stretches) activity for 7.5 minutes every hour during the night shift schedule. Over the course of the shift, subjects completed a battery of six tests providing data on physiological measurements (heart rate and temperature), performance criteria (reaction time responses, memory and neurobiological) and subjective measures. Responses obtained for all the different parameters measured indicated a strong circadian influence for the majority of the variables, indicating the course of natural down regulation within physiological and performance criteria over the night shift. The booster break significantly improved reaction time performance, subjective ratings and resulted in a high sustainable activity level. Day shift comparisons indicating that within subjective measures and reaction time performance, the booster break resulted in similar responses to those of the day shift workers, while the control night shift groups reported significantly lowers results. Additionally, the booster break had positive influences during the circadian nadir, significantly improving parameters of performance and subjective ratings of sleepiness. The results of this study indicating which variables are strong predictors and indicators of the oscillations in performance and subjective ratings due to the circadian changes. The booster break interventions had positive effects on subjective ratings and reaction time performance, while also being argued to decrease the burden placed on the cardiac system as a result of increased sympathetic tone during the night shift, while additionally resulting in similar responses to those of day shift workers. Further studies are required, however, to provide conclusive evidence particularly within a working situation over a longer shift schedule.

- Description: The hand is one of the most complex of all of the anatomical structures in the human body. It has been found that hand injuries are among the most frequent injuries that occur to the body, predominantly during industrial activities. It has therefore been concluded that more research is needed into protective factors, such as glove use. The design features of a glove emphasise either protection or performance. There is often a trade-off between increased safety and performance capability when donning gloves. It has been determined that gloves which are fitted and comfortable for the worker may provide the best compromise between protective functions and decreased performance. This investigation aimed to assess the influence of glove fit on the performance attributes of industrial tasks, as well as on the responses of the human operator. Glove fit was analysed as 35 male participants donned three different glove sizes during each test, including a best-fitting glove, a glove one size smaller than best-fitting, and a glove one size larger than best-fitting. For each glove size, gloves of two differing materials were tested, namely nitrile and neoprene. A barehanded condition was also tested, totalling seven gloved/barehanded conditions for each test. The seven conditions were assessed in a laboratory setting in a battery of tests. This consisted of components of task performance, including maximum pulling and pushing force, maximum torque, precision of force, tactility, speed and accuracy and dexterity. The performance responses were recorded, as well as participants’ perceptual responses using the Rating of Perceived Exertion scale, and muscle activity. Six muscles were selected: Flexor Digitorum Superficialis, Flexor Pollicus Longus, Extensor Carpi Ulnaris, Extensor Carpi Radialis, Flexor Carpi Ulnaris and Flexor Carpi Radialis. The results revealed that glove fit does affect certain spects of performance, and influences human operator responses for selected task components. Furthermore, discrepancies were distinguished between orking barehanded and working with an optimally fitted glove. There was also a glove material effect established. Overall, it was found that muscle activity when exerting maximum force in a pushing and pulling direction was optimal with the nitrile glove material. Maximum torque performance was enhanced with the use of a best-fitting glove, as compared with an ill-fitting glove or barehanded work. Force precision was preferable when barehanded, as opposed to the tactility task which rendered optimal results with a best-fitting glove. The same was found for speed and accuracy results, as glove fit appeared to have no effect on performance, but performance was improved when participants were barehanded. Dexterity performance was the most conclusively influenced by the conditions, resulting in barehanded performance being optimal. However, should a glove be necessary for a given task, an optimally-fitted glove which is of a thinner material would be recommended. It is necessary to distinguish the performance components of a task within industry and select the most appropriate glove for optimal performance and the least risk of overexertion.

- Description: Less than two decades ago, Zimbabwe was a symbol for the rest of the world of what Africa could become (Dell, 2005). DiSilvio (2007) contends that independent Zimbabwe was an economic success on route to attaining status of the most “developed country” in Africa. Contrary to expectations, by 2003 the Zimbabwean economy was shrinking faster than any other economy in the world at 18 percent per year (Richardson, 2005). Reports indicate that the Zimbabwean economy is in crisis and has since been set back by more than 50 years (Matikinye, 2005). This phenomenon necessitated the need for an investigation to ascertain its cause in Zimbabwe. As a result, the research identifies and presents hyperinflation as the root cause of the crisis in Zimbabwe and illustrates the validity of this assertion with a focus on the Zimbabwean construction industry. As part of the research inquiry, a review of related literature was conducted. The literature review illustrated the generic effects of hyperinflation as well as the effects of this phenomenon in action in Zimbabwe. The literature study was followed by a questionnaire survey. The questionnaire was completed by 23 contractors and 7 clients from a census of contractors and clients in Zimbabwe. The questionnaire consisted of a number of variables, which the respondents were asked to rate vis-à-vis the effects of hyperinflation in the construction industry. In summary, the questionnaire sought to determine the causes of hyperinflation in Zimbabwe, its specific effects on the construction industry and how respondents thought the phenomenon could be mitigated so as to revive the Zimbabwean construction industry. The techniques of re-scaling, in conjunction with descriptive and inferential statistics, ranking and quadrant analysis were applied to the data. Results from these analyses revealed a high degree of agreement among respondents vis-à-vis the effects of hyperinflation on the Zimbabwean construction industry. The interpretation of the results further revealed that hyperinflation has undoubtedly led to the collapse of the Zimbabwean construction industry. In conclusion, the research, applying the interpretations of v the survey findings, prescribes a number of ways in which the Zimbabwean construction sector may be resurrected. Among the recommended prescriptions, there are a number of debatable issues that arise that the researcher proposes should be subject to future study.

- Description: Recently, bankers have come to realise that banking operations, especially corporate lending, affect and are affected by the natural environment and that consequently, the banks might have an important role to play in helping to raise environmental standards. Although the environment presents significant risks to banks, in particular environmental credit risk, it also perhaps presents profitable opportunities. Stricter environmental regulations have forced companies to invest in environmentally friendly technologies and pollution control measures and in tum generated lending opportunities for bankers. This research examines the corporate practices of three of the four dominant banks in South Africa with respect to the environment, focusing on issues of climate change and environmental risk management by way of reporting and disclosure to all stakeholders. The emphasis on environmental reporting by South African banks has been reinforced by the latest release of the King III Report on Corporate Governance in South Africa. Global governance requires that the triple-bottom line should be applied in all corporate undertakings due to globalisation and trade liberalisation; however, the banking sector has responded poorly to the clarion call. The false view that the banks have no significant relationship with environmental degradation is being disproved. Environmental management is a huge and massive reconstruction of what has gone wrong with nature by human influence. The South African banks have had to face with the challenging tasks of reporting on the direct and mostly the indirect impacts of their environmental activities. Based on the three sampled banks which incidentally had greater percentages of the market capitalizations, the banks have fairly performed in environmental reporting. For example, Standard Bank (SA) Ltd has just signed the Equator Principles in 2007 implying corporate lending was done in 2007 without any respect to environmental impact assessments by corporate borrowers. Consequently, environmental reporting was not done to facilitate informed decision-making by stakeholders mostly shareholders and the communities where borrowers tun businesses. The objective of this research study is to investigate the extent and quantity of/voluntary environmental disclosures in the annual and sustainability reports of the banks listed on Johannesburg Stock Exchange. The periods examined were those subsequent to the release of the Exposure Draft Coalition for Environmentally Responsible Economies (CERES) Global Reporting Initiatives (GRI) issued in 1999. Using content analysis to focus on the environmental aspects, the research study compared three annual reports and three sustainability reports of 2007 year for the three sampled banks in order to evaluate reporting practices in the period surrounding this intervention. The results suggest a trend to triple bottom-line reporting and the extent and quantity of environmental information, albeit in specific categories.

- Description: Social Interaction Technologies (SIT) have broadened the horizon of communication in terms of the way people are able to communicate. It is now possible to interact with others across the world and engage in numerous activities ranging from dating to political movements, hobbies and even professions (Chigona, Chigona, Ngqokelela, & Mpofu, 2009). Adolescents and pre-adolescents especially are inclined to make use of SIT in their social lives with the most popular mode of communication, apart from email, being instant messaging (IM) (Brown, Mounts, Lamborn, & Steinberg, 1993; Bryant, Sanders-Jackson, & Smallwood, 2006; Madden & Rainie, 2003). Adolescents tend to use IM regularly as a tool to maintain relationships and girls especially, use it as a tool to socialise (Jennings & Wartella, 2004; Lenhart, Rainie, & Lewis, 2001). The mobile phone or cell phone, which is another example of an SIT-based communication, has become an established medium of technical, social and commercial communication in South Africa. It has given rise to the development and vast growth of a mobile youth culture who consider it an essential tool for communicating (Bosch, 2008). In South Africa, instant messages may be sent via mobile phone using one of two methods: MXit and the SMS (short messaging service). MXit and the SMS are considered convenient tools of communication as an ongoing conversation in the form of a text message may be maintained in the present (Yoshii, Matsuda, Habuchi, Dobashi, Iwata, & Kin, 2002).

The Palmgren – Miner damage accumulation hypothesis is widely used in determining the fatigue life of components exposed to variable loading conditions. Modifications have been made to this hypothesis trying to achieve a greater degree of accuracy, of these the Liu – Zenner modification has been the most successful. In this report the systematic process of fatigue life prediction using the Liu – Zenner modification to achieve reliable results is calculated. A representative stress time history measured in service on the component forms the basis for defining a flight cycle which is the chosen unit in which to express the fatigue life. Rainflow cycle counting performed on the stress time history allowed the formulation of a load spectrum to which the component is exposed in one cycle. Combining the load spectrum with the developed SN curve of the component and using the Liu – Zenner modification to the Palmgren – Miner rule a reliable fatigue life in cycles is predicted.

- Description: The South African Health Care environment is in state of reform. Government strategy and change in legislation have been the catalyst for the development of new business models in South Africa. This report deals with the feasibility of a proposed model which is to be implemented by the Eastern Cape Department of Health at the Provincial Hospital in Uitenhage. The fundamental challenge in South Africa is the shortage of resources to support the health care industry from a public perspective. The point of departure for this research was to understand the complexity of this industry and investigate models that have evolved in South Africa and internationally. The literature research covers funding mechanisms from both a public and private perspective and takes into account the role the government plays in providing equitable health care for all. The literature provided the foundation to develop the model which is to be piloted at the hospital in Uitenhage. In terms of the research objective, a single case study methodology approach was conducted. Triangulation technique was used to gain insight from different perspectives and to test the model for validity. The core of this research focuses on the viability of the proposed model and the integration of this into the government health reform plan. The research revealed that in comparison to the existing PPP models in South Africa, this model is feasible. As a result of the analysis and the development of the proposed model, the research is concluded by offering suggestions for further research.

- Description: Selected outcrops of the Upper Devonian to Lower Carboniferous, Witteberg Group, Cape Supergroup were mineralogically and structurally analyzed. The study area is located approximately 30km northwest of Kirkwood and 10km south of Darlington Dam, Eastern Cape, South Africa. Strata predominantly consist of arenaceous Witpoort Formation, which includes the Perdepoort, and Rooirand Members. The Perdepoort Member is a thinly bedded quartzite also known as the "white streak". The Rooirand Member quartzite is a highly iron stained red-brown quartzite. The dark-grey, pyritic rich shales of the Kweekvlei Formation overlie the Witpoort Formation in the southern half of the study site. These shales are highly deformed and display closely spaced thrust faults and close folds. The study area encapsulates a range of folding from tight to open folds. Faulting consists of low angle north verging thrust fault, south verging back thrusts, south and north dipping normal faults, and strike-slip faults. Closely spaced, fore-land verging thrusts faults predominate over hinterland verging back thrusts. Normal faulting post-dates thrust faulting and utilized weaknesses in axial planar cleavage and in certain instances existing thrust fault planes. Strike-slip faulting post-dates thrusting and has in places reactivated pre-existing thrust fault planes. Macro scale folding includes overturned synclines and large anticlines which have been eroded, exposing older strata. Fold axes plunge at low to moderate angles west-southwest. This correlates with tension gashes which indicate north westward directed forces. Eastward directed forces are confirmed by the presence of tension gashes and strike-slip movement. The local geology displays north westward directed compression followed by strike-slip movement. Normal faulting post-dates all other structures and is associated with the Mesozoic break-up of Gondwana. The Perdepoort Member was sampled along strike, at different outcrop latitudes. Seven samples were selected for scanning electron microscope analysis. Samples are composed almost entirely of quartz; accessories include, biotite, muscovite, sericite, baryte, and apatite. Epigenetic hematite is present along cracks within certain samples Epigenetic hematite occur along cracks with oxides and phosphates in the form of rutile, apatite and monazite present in a number of samples. When compared to other silica extraction operations the Perdepoort Member appears viable for explotation. However, for the solar cell industry the purity of this horizon is clearly far below that required for industy.

- Description: This dissertation investigates the effects of the financial crisis on the South African economy. In order to do this, an index which describes the financial conditions of the South African economy is constructed and computed. The index indicates that domestic South African financial conditions have deteriorated substantially during the period under study and so the study investigates how this has impacted on the country’s economic growth. A VAR model with South African variables is specified and used to assess the quantitative effects of the financial crisis on South African real GDP growth. Results suggest that the South African economy was not significantly affected by the crisis, but economic growth was slowed down and may still grow substantially slower in the next few years due to the financial crisis. These results corroborate the theoretical predictions and are also supported by previous studies.

- Description: The spatial and temporal patterns in selected components of the ichthyofauna and piscivorous avifauna in the small temporarily open/closed Riet River Estuary located on the eastern seaboard of southern Africa was investigated monthly over the period August 2005 to July 2006. The ichthyofauna within the littoral zone of the estuary was sampled using a 5 m seine net (8 stations) while a 30 m seine net (4 stations) was employed to sample the fish in the channel. Bird counts were made along repeat transects along the length of the estuary. Total ichthyofaunal abundances and biomass ranged between 1.60 and 8.67 individuals m⁻² and 0.45 to 21.76 g wwt m⁻² within the littoral zone, and between 0.08 and 0.44 individuals m⁻² and 0.58 and 36.52 g wwt m⁻² in the channel of the estuary. The highest values were generally recorded during the summer months. Results of the numerical analysis indicated that the breaching events recorded over the study period did not lead to a common trend in the ichthyofaunal community. In the absence of a link to the marine environment, the ichthyofaunal community in the littoral zone was numerically dominated by the estuarine resident species, Gilchristella aestuaria and to a lesser extent by Glossogobius callidus, which collectively accounted for ca. 54% of the total ichthyofauna sampled. The establishment of a link to the marine environment coincided with increased numbers of marine breeding species including Atherina breviceps and Rhabdosargus holubi to total fish counts within the estuary. Hierarchical cluster analysis did not identify any spatial patterns in the community structure of the ichthyofauna in the littoral zone or channel zone of the estuary, which could likely be linked to the absence of any distinct horizontal patterns in salinity and temperature within the system. A total of thirteen piscivorous bird species was recorded over the study period. Of the recorded species, six species were wading piscivores, four species were aerial divers and the remaining three species were pursuit swimmers. There were no significant correlations between the estimates of the ichthyofaunal abundance and biomass and bird numbers evident during the study (P> 0.05 in both cases). The Reed Cormorant (Phalacrocorax africanus) was the dominant species throughout the study, with a mean of 8.25 (SD ± 7.90) individuals per count. Mean values of the Pied Kingfisher (Ceryle rudis) and Giant Kingfisher (Megaceryle maximus) were 3.42 (SD ± 1.20) and 1.17 (SD ± 0.60) individuals per count, respectively. The remaining species revealed mean values < 0.5 individuals per count. The highest bird numbers were recorded in winter reflecting the migration of large numbers of the Reed Cormorant into the system. Breaching events were associated with a decrease in total bird numbers, which was most likely due to loss of potential foraging habitat (littoral zone) for waders resulting from reduced water levels. Monthly food consumption by all piscivorous birds revealed large temporal variability, ranging from 26.35 to 140.58 kg per month. The observed variability could be linked to mouth phase and bird numbers.

- Description: The current trends in sustainable development (SO) were examined in this study, which brought about the realisation that SO has become a business imperative. Mining, which is a highly impacting industry, is faced with the dilemma of implementing the principles of SO despite the realisation that its activities are severely limited by· the finite nature of the resource it is capitalising on. This reality, however, does not detract from the non-negotiable requirement for the industry to meet the increasing pressures to act responsibly towards the environment and the community in which it operates. Gold Fields has stepped up to the plate and has already taken several steps to achieve this end. These include the adoption of SO in its Vision, Values and strategies and the development and implementation of a SO framework to ensure the integration of the principles of SO into the business. Furthermore, Gold Fields has also entered into voluntary activities that further cement the commitment the company has towards so. These other initiatives include, inter alia, its International Council on Mining and Metals membership, UN Global Compact participation, becoming a signatory to the cyanide code, IS014001, and so on. This study focussed on several indicator categories and the identification of a set of supporting sustainable development indicators (SOls) for each, which included environmental, social, economic, technological, and ethics, legal and corporate governance (not in order of priority). These indicators were assessed by a carefully selected group of respondents whose collective wisdom and expertise were used to identify and weight supporting SOls for each of the indicator categories. These supporting SOls were in turn used to develop a model that is able to assist in the business's decision making processes when capital investment is being considered . A water treatment project that is currently being considered by Gold Fields was utilised to demonstrate how the decision making model can be applied to two different scenarios. The result clearly and successfully demonstrated that by proactively taking environmental, economic, social, technological, and ethics, legal and corporate governance considerations into account, a gold mining company is able to increase the level of SO of a capital investment project.

- Description: Napping has been explored extensively as a means of counteracting the negative effects associated with shift work. A significant amount of this research has focused on the implementation of scheduled naps, with few studies considering flexible nap schemes. The current study therefore aimed to assess the effects of a flexible nap opportunity on the physiological, cognitive, performance, neurophysiological and subjective responses of a group of non shift workers over the course of a three-day simulated night shift regime. Additional foci were the effects of the nap condition on the extent of the circadian adaptation of the subjects to the irregular work schedule and the circadian-related influences associated with being awake during the night. 36 subjects – 18 males and 18 females – were recruited to participate in the current study. The data collection spanned twelve days, during which four, three-day long shift cycles were set up: three night shift cycles and one day shift cycle. During each night shift cycle, three separate experimental conditions were staggered, namely the nap condition, the no nap condition and a booster break condition (a collaborative study that completed the setup). The day shift served as a further comparison. Each cycle comprised of 12 subjects, which meant there were four subjects per condition during each cycle. The shifts were 8 hours in duration, with the no nap group following a standard break schedule evinced in industry. The three breaks taken during the shifts amounted to a total time of 1 hour. The nap group was afforded a 1 hour flexible nap opportunity between 00h00 and 03h00 with no other breaks. Therefore, both conditions had the same amount of work time. During the shifts, subjects performed two simple, low arousal tasks (beading and packing) and completed a test battery roughly every two hours which was comprised of physiological, performance, neurophysiological and subjective measures. It was found that the inclusion of the nap opportunity significantly improved output performance and response time during a low precision, modified Fitts tapping task over the course of three night shifts, relative to no napping. Physiologically, napping resulted in higher heart rate frequency measures by the end of the shifts, which were also accompanied by significant reductions in subjective sleepiness ratings during all iii the night shifts. The nap group’s responses in this case, did not differ significantly from those of the day shift. Both simple reaction time and memory performances improved as a result of the nap inclusion, but only during the third night shift. The majority of the measures included in the research also depicted the effects of the circadian rhythm, which was indicative of the pronounced effect that this natural biological down regulation has on performance during the night. Napping reduced the severity of these effects during beading performance and measures of subjective sleepiness. With regard to habituation, the nap opportunity also resulted in positive changes in the responses of beading performance, high precision response time, simple reaction time and both subjective sleepiness measures, relative to no napping. Sleep diary responses indicated that although sleep length and quality during the day were significantly reduced for both night-time conditions, recovery sleep (length and quality) for the nap group did not differ significantly from the no nap group. The findings of this research indicate that the inclusion of a flexible napping opportunity during the night shift had positive effects on some physiological, performance and subjective responses, and that this intervention is as beneficial as scheduled napping. Specifically, napping resulted in a significantly higher output during the beading task, relative to the no nap group despite the duration of work time being the same. As such the introduction of a flexible, self-selected nap opportunity is a practical, effective and individual-specific means of alleviating the negative effects of shift work, while improving certain performance parameters. Therefore, industries should consider its inclusion in their fatigue management programs. However, contextspecific considerations must be made, with regard work scheduling, individual differences and task demands when implementing such an intervention. This will ensure that its introduction will be well received and in time, lessen the health and work-related decrements associated with shift work.

- Description: Napping has been explored extensively as a means of counteracting the negative effects associated with shift work. A significant amount of this research has focused on the implementation of scheduled naps, with few studies considering flexible nap schemes. The current study therefore aimed to assess the effects of a flexible nap opportunity on the physiological, cognitive, performance, neurophysiological and subjective responses of a group of non shift workers over the course of a three-day simulated night shift regime. Additional foci were the effects of the nap condition on the extent of the circadian adaptation of the subjects to the irregular work schedule and the circadian-related influences associated with being awake during the night. 36 subjects – 18 males and 18 females – were recruited to participate in the current study. The data collection spanned twelve days, during which four, three-day long shift cycles were set up: three night shift cycles and one day shift cycle. During each night shift cycle, three separate experimental conditions were staggered, namely the nap condition, the no nap condition and a booster break condition (a collaborative study that completed the setup). The day shift served as a further comparison. Each cycle comprised of 12 subjects, which meant there were four subjects per condition during each cycle. The shifts were 8 hours in duration, with the no nap group following a standard break schedule evinced in industry. The three breaks taken during the shifts amounted to a total time of 1 hour. The nap group was afforded a 1 hour flexible nap opportunity between 00h00 and 03h00 with no other breaks. Therefore, both conditions had the same amount of work time. During the shifts, subjects performed two simple, low arousal tasks (beading and packing) and completed a test battery roughly every two hours which was comprised of physiological, performance, neurophysiological and subjective measures. It was found that the inclusion of the nap opportunity significantly improved output performance and response time during a low precision, modified Fitts tapping task over the course of three night shifts, relative to no napping. Physiologically, napping resulted in higher heart rate frequency measures by the end of the shifts, which were also accompanied by significant reductions in subjective sleepiness ratings during all iii the night shifts. The nap group’s responses in this case, did not differ significantly from those of the day shift. Both simple reaction time and memory performances improved as a result of the nap inclusion, but only during the third night shift. The majority of the measures included in the research also depicted the effects of the circadian rhythm, which was indicative of the pronounced effect that this natural biological down regulation has on performance during the night. Napping reduced the severity of these effects during beading performance and measures of subjective sleepiness. With regard to habituation, the nap opportunity also resulted in positive changes in the responses of beading performance, high precision response time, simple reaction time and both subjective sleepiness measures, relative to no napping. Sleep diary responses indicated that although sleep length and quality during the day were significantly reduced for both night-time conditions, recovery sleep (length and quality) for the nap group did not differ significantly from the no nap group. The findings of this research indicate that the inclusion of a flexible napping opportunity during the night shift had positive effects on some physiological, performance and subjective responses, and that this intervention is as beneficial as scheduled napping.

- Description: Economical and educational problems are caused by the reversed effect of the Employment Equity Act and Affirmative Action. One such problem is called “brain drain” (Lundy, 2006), The general aim of the research was to determine whether affirmative action caused final year students of the Nelson Mandela Metropolitan University to consider overseas employment. A literature study was conducted before the empirical objectives were reached. The empirical study was of a quantitative descriptive and inferential nature. A cross-sectional survey design was used to achieve the empirical objectives. A self- administered survey package was handed out to final year students within the various disciplines at their various classes. One hypothesis was tested. The results indicated that support was found for the hypothesis. The findings are discussed in relation to the data gathered. The implications of the research and the limitations of the study are outlined in the Results chapter.

- Description: Purpose – The primary aim of the study was to establish to what extent company vision impacted on productivity, profitability, morale and the quality of product at Borbet SA. Borbet SA is an aluminium wheel manufacturer situated in Port Elizabeth, Eastern Cape, South Africa. The secondary aim of the study was to establish whether the vision would be reached by applying the company values in action at Borbet SA. Methodology – Seventy-seven respondents employed at Borbet SA completed a Likert Scale Questionnaire to measure their knowledge and application of the company vision and values. The research study made use of a combination of qualitative and quantitative research approaches. The research study was qualitative as the topic was subjective to perception of the participants. However, the data was to be analyzed quantitatively through statistical practices. Findings – Overall, the participants were 99 percent aware of the vision statement at Borbet SA. Therefore, Borbet SA had succeeded in making company vision a part of their business strategy. The successful implementation of a vision and values at Borbet SA have improved productivity, profitability, morale and quality of product at the company. The study’s main findings were that employees between the ages of 18 – 29 years were especially optimistic of the company vision and values. Employees working at Borbet SA for between 4 – 5 years and working at Borbet for between 0 – 3 years tended to be more unenthusiastic about company vision and values. Middle management, including supervisors and team leaders, were also pessimistic about certain aspects concerning the vision of the company. Research limitations – One of the limitations of the research were that only 77 of the workforce completed the voluntary questionnaire. The questionnaire was in English and this was not the first language of the majority of the employees at Borbet SA. This could have prevented them from completing the questionnaire because they might not have felt confident in responding in ii English. Educational levels could also have influenced the response to the questionnaire seeing that not all employees had the same educational levels and, thus, this could have been intimidating. Recommendations – The main recommendation was that a mentoring programme be implemented in which younger and older employees could motivate each other and build morale. The management of Borbet SA was recommended to have team building sessions with middle management, supervisors and team leaders to build morale and optimism in these groups. Employees working for 4 – 5 years needed to be evaluated and motivated as some of them could have felt stagnant in their job positions.

- Description: The purpose of this treatise is to ascertain the impact of economic downturn on Black Economic Empowerment (BEE) and Banks. This has been sparked by the huge speculations in the market as to what will happen to BEE and how will the banks cope in general with the impact of this scourge. It is imperative to understand the influence of the 2008+ economic downturn on socio-economic reconstruction and development in South Africa and the black economic empowerment and its funding mechanisms. The treatise has two phases the, namely the theoretical phase and a bit of narrative phase. In the theoretical phase the research study interrogates what the literature review reveals about the economic downturn, BEE as well as performances of different banks across the world. This shows the economic impact that the banks have had to endure during the economic downturn. This resulted in stock markets losing their value. The dividend earners were significantly affected including a sizeable number of BEE companies. The BEE companies are perceived to be too reliant on debt on to finance their deals and this treatise will look at various options of financing a BEE deal and what is deem to the most suited financing structure. The narrative phase involves semi-structured interviews that were conducted in order to ascertain the real impact that South African were faced with and how they have managed to steer clear of the turbulent waters. This also looked at how the BEE consultant views the current occurrences in the market.

- Description: Introduction: Adherence to Highly Active Antiretroviral Therapy (HAART) is critical for optimal therapeutic outcomes. A possible factor in adherence is the impact of HAART on sexual functioning. Methods: A mixed methods approach was used. A cohort of 14 people living with HIV/AIDS (PLWHA) in Grahamstown was identified. Two semi-structured interviews and two structured questionnaires were administered. In-depth interviews were conducted with two HIV counsellors in so as to obtain a different perspective on the topics. The theoretical framework used three health behaviour models: the Health Belief Model, Leventhal‘s Common-Sense Model of self regulation and the Transtheoretical model. Results: The participants were between 27 and 49 years old and had been on HAART for between 9 months and 10 years. Six participants were support staff members from Rhodes University and eight from the Raphael Centre – a local NGO which assists PLWHA.In most of the participants HAART was associated with increased libido and improved sexual functioning (sexual activity and sexual enjoyment). The use of alcohol increased risky sexual behaviour. Issues of adherence were seemingly not directly affected by the effects of HAART on sexuality. PLWHA, especially women, face challenges related to their sexuality, some of which are not directly related to their illness and treatment. The fear of transmitting drug resistant HIV or getting re-infected, stigma, disclosure issues,difficulties negotiating for safe sex among women, HAART-related lipodystrophic changes that affect one‘s sense of self and unmet reproductive needs are some of the problems that were reported. The men‘s dislike for condoms was overt and blatant. Discussion: Being diagnosed with HIV and reaching a point where treatment is requiredare life-changing events. Making decisions about one‘s life (including adherence to HAART, alcohol use and knowingly partaking in risky sexual encounters) become all the more significant in the context of AIDS. Intentional non-adherence is informed by the individual‘s assessment of the costs and benefits of taking treatment. Cultural influences,gendered power relations and misconceptions strongly influence sexual behaviours. Conclusion: The general lack of attention among health care providers concerning issues related to PLWHA‘s sexuality and reproductive issues needs to be addressed. Insights fromthe theoretical models should be integrated with empirical findings in designing adherence interventions.

- Description: This study investigates the impact of ICTs for agricultural development in the Alice rural community. The rationale for carrying out the study has to do with the limited access to ICTs by farmers residing in this rural community which in turn affects their productivity and increase in the volume of agricultural production. The core argument of the study is that the use of ICTs has positive spinoffs on agricultural development which leads to improvement in the quality and quantity of agricultural production. Conversely lack of access to ICTs can result in inability to enhance agricultural productivity in rural areas such as Alice. Furthermore, it is argued herein that technological information devices such as ICTs are essential communication and information tools; and as such, should be regarded as useful communication media for disseminating relevant agricultural information to farmers residing in rural communities. In conducting this study theoretical frameworks such as Rogers’ diffusion of innovation and development theories encompassing both the participatory approach and development support communication were presented and argued for as approaches suitable for the study. Triangulations of research methods, such as, qualitative and quantitative methods, were utilized for the collection of data for this study. As is common practice, the triangulation method was used in cross checking and supplementing data/information collected through the utilization of each of the methods. Interviews and questionnaires were used as data collection tools for this study owing to their ability to generate clear and precise responses or answers to the questions posed. The key findings of the study show that the limited access to ICTs in the Alice rural community was caused by factors such as low level of literacy, age and language barriers which in turn affected the adoption of ICTs amongst the Alice farmers. Amongst the recommendations emanating from this study is the idea that the adoption of ICTs for agricultural information can be fast-tracked through the implementation of telecentres/kiosk and information centers for easy access to information and communication services in the rural community.
