- Description: I argue that a specific version of Theory theory is necessary and sufficient for attributions and predictions of others' emotions. Theory theory is the view that we attribute and predict others' mental states on the basis of a (tacit) body of generalisations about mental states, their situational input, and behavioural output. Theory's antagonist, Simulation theory, is the view that we ascribe mental states to others by simulating - or running ' off-line ' - their doxastic, emotional, and contextual situations. My argument for Theory's necessity and sufficiency develops in three stages: First, I show that some version of Theory is necessary for predictions of all mental states on the basis of the ascriber's knowledge of the subject's other mental states. The linchpin of the arguments here consists of considerations from relevant similarity between the ascriber's and the subject's mental states. Simulation cannot provide criteria for such similarity, and so, I argue, predictions must advert to Theory. Second, I develop a sui generis model of emotions, according to which (i) emoticns' necessary objects and typical causes are concern-based construals; and (ii) emotions qua attitudes are (a) complex states embedded in a narrative structure, (b) characterised in terms of their object, their expressive behaviour, and their phenomenology. Third, I show that, considering the nature of the objects of emotions, some Theory is necessary for emotion-predictions and -attributions. Moreover, I develop a version of Theory, based on my analysis of emotions and narrative structures, and argue that this version of Theory is both necessary and sufficient for emotion-predictions and -attributions.

- Description: The aim of this study was to create a profile of the agricultural tourism industry in the Garden Route area of South Africa, and to determine what general influence agricultural tourism has on the macro environment (rural area) with regard to socio- economic development, as ell as on the micro environment (farm) with regard to the generating of additional income. This study only includes agricultural operations (farms) in the Garden Route area that practice tourism activities. Out of 54 potential agricultural units that were identified, 46 were willing to participate in the study. Information from only 40 of the abovementioned units was finally included in this study. Six agricultural units could not supply sufficient information during the surveys. Data were gathered by means of a scientifically compiled questionnaire. All the individuals involved in this study completed this questionnaire by means of a personal interview. The aspects investigated in order to compile a profile were the characteristics of the suppliers, activities and the extent of the agricultural tourism industry. In order to determine the contribution of agricultural tourism on micro- and macro levels, aspects such as the contribution to farming turnover were investigated as well as the socioeconomic contribution in view of the infrastructure development, job creation, education and housing. The results of this study indicate that 78% of respondents are aged 40 years and older, are mainly male, and, in most of the cases, married (95%). Agricultural tourism enterprises in the Garden Route area are, in most cases (60%), managed by the farmers’ wives. The business type whereby respondents’ agricultural tourism enterprises are conducted, is as follows: in 72.5% of the cases a sole ownership, 17.5% a private company, 5% a partnership, 2.5% a closed corporation and the other remaining 2.5% is managed as a trust. The majority (65%) of persons involved in the management of the agricultural tourism enterprise has received some form of tertiary education. A degree of statistical significance (p = 0.0728) exists between the education level of the type of person/persons that manages the tourist branches and the type of activity category that is offered. In 65% of the cases the farms that offered agricultural tourism, were smaller than 500 hectare. A negative correlation (r² = -0.31700; p<0.0001) was found between farm size and the total farming turnover per year. This trend is even more distinctive (r² = -0.47156; p<0.0001) for farms smaller than 1 000 ha. A statistically meaningful (p = 0.0115) relationship exists between farm size and the number of activities that were offered. This occured in cases where farms were smaller than 1 000 ha. In 25% of the cases only one agricultural tourism activity was offered, 12.5% of these farms were 100 ha or smaller. The maximum number of activities that were offered was 11 and it was found in 3.13% of the cases. A highly statistically meaningful (p = <0.0001) connection exists between the percentage tourism turnover per year and the different types of activity categories that were offered. In 35.75% of the cases these activity categories earned between 1 and 10% of the yearly tourism turnover. A highly statistically meaningful (p = 0.0036) connection also exists between the degree of popularity and the type of activity category that was offered. In 53.07% of the cases the most popular activities were those that are nature-based, followed by accommodation-based activities (23.46%). In 82.5% of the cases additional income was the main reason for offering agricultural tourism. Other distinctive reasons were the love for people (50%) and the desire to share the farm life and beauty with others (25%). The tourism activities that were offered on the farms were respectively, guest houses (62.5%) followed by hiking trails (57.5%) and swimming opportunities (32.5%). Wildlife viewing was the activity that has been offered for the longest period of time, some 11,5 years. The general location of the agricultural tourism operations were 21.9 km from towns and 9.65 km from main routes. Word-of-mouth was the most successful marketing method, followed by the use of own brochures (90%) and local tourism bureau brochures (87.5%). A degree of statistical significance (p = 0.0902) exists between the number of marketing methods and the average percentage of the tourism branch as a total part of the total farming turnover per year. A positive correlation (r² = 0.29118; p<0.0001) exists between the number of marketing methods and the total farming turnover per year. Visitors to the agriculture tourism operations were in 55% of the cases mainly domestic tourists, followed by 25% that includes both domestic and foreign tourists, and a further 20% that mainly includes foreign tourists. The majority (67.5%) of operations indicated that agricultural tourism formed less than 30% (between 2% and 30%) of their annual agricultural turnover, 5% between 30% - 50%, 25% between 80% - 100% of their turnover, while 2.5% generated no income from agricultural tourism. A highly statistically meaningful (p = 0.0010) relationship exists between the percentages that the tourism branch contributes as a total of the farming turnover per year and the number of years that the respondents hade been involved in the offering of agricultural tourism. A positive correlation (r² = 0.30005; p<0.0001) exists between the number of years involved with the offering of agricultural tourism and the average percentage of the total farming turnover per year. New infrastructure was created by 40% of the providers, a further 12.5% partially created new infrastructure, while 47.5% made use of infrastructure that was already in place. Thus far job opportunities have been created for 58 people of whom 13.79% are male and 86.21% are female. A statistically meaningful (p = 0.0406) relationship exists between the number of workers that had to be appointed additionally and the number of activities that were offered. In 17.5% of the cases it was only needed to appoint one worker, followed by 2.5% that appointed three workers each, 5% that had to appoint four workers each and a further 2.5% that had to appoint seven workers each. There are 27.5% of agricultural tourism providers that had to appoint additional workers, 20% provided education to those workers and 36.36% of the above-mentioned provided housing to those workers and their dependants. A statistically meaningful (p = 0.0209) relationship exists between education provided to workers that had to be appointed additionally and the type of activity combination that was presented. A degree of statistical significance (p = 0.0691) exists between housing provided to additional workers and the number of activities that were presented. A statistically meaningful (p = 0.0455) relationship further exists between housing provided to workers that had to be appointed additionally and the type of activity combination that was presented. From the results of this study it appeared that the development of agricultural tourism in the Garden Route area has a positive impact on the micro- and macro environments of the rural areas. This impact can make a direct or indirect contribution to the socio-economic development of this region and it can induce the generation of additional income, infrastructure development, job creation, education and housing. This study suggests that there is significant potential for the further development and exploitation of agricultural tourism.

- Description: With the rapid development of wireless technologies, traditional mobile devices, such as pagers and cellular phones, have evolved from a purely communications and messaging-oriented medium to one that supports mobile data communication in general and acts as an application platform. As shown in a recent survey conducted by MDA, easy access to the present-day wireless Internet has resulted in mobile devices gaining more and more attention and popularity. The growth of and demand for mobile Web applications is expected to increase rapidly in the near future, as a range of software companies and mobile device manufacturers release increasingly accessible tools for creating mobile Web application and services. From a variety of possible development environments of this kind, the author has selected and examined two leading contenders, the J2ME and the Microsoft .NET mobile Web application development environments. This document reports the product life cycle of pilot mobile web applications, designed and implemented in each host environment in tum. A feature-by-feature investigation and comparison of the J2ME and .NET environments was carried out, covering the range of issues necessary for a complete mobile Web application development life cycle. The resulting analysis addresses features and efficiencies of the application development environment and the target deployment environment, the degree to which the resultant services are compatible on a variety of platforms, and the ease with which applications can be designed to be extensible. The thesis offers an objective evaluation of the J2ME and the .NET mobile development environments, which highlights their strengths and weaknesses, and suggests guidelines for designing, creating, and deploying high quality mobile Web applications. The research uncovers no clear winner across all categories assessed. J2ME currently favours situations in which bandwidth is limited and client side processing power is relatively sufficient, it exerts the processing power of mobile devices over distributed network environments. .NET requires a less constrained network throughput, but performs adequately on clients with more limited processing power, supports a more diverse target platform range, and offers a more efficient, in terms of development time, development environment. Both technologies are likely to receive significant user support for some time. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The aim of this study was to generate useful isokinetic normative data for various cervical musculature strength, range of motion and ratio variables based on different positional categories in a sample of senior elite South African rugby players. Normative data was generated for the following variables: peak torque, power generated at 0.2 of a second, active and passive range of motion, the ratio of peak torque flexion to peak torque extension (PTF/PTE), the ratio of peak torque lateral flexion left to peak torque lateral flexion right (PTL/PTR), the ratios of peak torque to body weight (PT/BW) and the ratios of peak torque to lean body mass (PT/LBM). Furthermore, the data gathered from the senior elite players was compared to similar data obtained from a sample of schoolboy rugby forwards to detect statistically significant differences (p < .05). A normative survey design was used in which 189 subjects from eight provincial unions participated in a one off evaluation session. The evaluation session comprised of various anthropometrical measurements and an isokinetic cervical musculature assessment. The normative data, displayed in Stanine tables, was generated for four positional categories: the front row (# 1-3), the second row (# 4-5), the back row (# 6-8) and the backline (# 9 -15). The second row positional category performed the best on the peak flexion torque variable (44.04 Nm). The front row positional category achieved the largest average peak extension torque (65.6 Nm). The second row positional category achieved the largest average peak lateral flexion right torque (69.42 Nm). A similar result was observed with the measurement of peak lateral flexion left torque, with the second row positional category achieving the largest average peak lateral flexion left torque (66.31 Nm). The backline positional category achieved the lowest averages on all the abovementioned peak torque variables. The front row positional category performed the best on the flexion power generated at 0.2 of a second variable (160.92 W). The front row positional category again achieved the largest extension power generated at 0.2 of a second average (237.02 W). The second row positional category achieved the largest lateral flexion right power generated at 0.2 of a second average (269.81 W). Similar results were observed with the measurement of lateral flexion left power generated at 0.2 of a second. The second row positional category achieved the largest lateral flexion left power generated at 0.2 of a second average (259.62 W). Again the backline players achieved the smallest power generated at 0.2 of a second averages for all the above-mentioned power variables. The measurement of passive (PROMFE) and active (AROMFE) range of motion for flexion to extension revealed that the second row had the largest average PROMFE (125.44°). The measurement of AROMFE revealed a similar result. The second row again had the largest average AROMFE (108.45°). The measurement of passive (PROMLF) and active (PROMFE) range of motion for lateral flexion left to right revealed smaller and different results to those found for PROMFE and AROMFE. For the variable of PROMLF the backline players had the largest average PROMLF (119.44°). Conversely, the second row had the largest average AROMLF (106.96°). The calculation of the various ratios revealed great variation between the positional categories. This can be attributed to the functional requirements the players have to adhere to, to be successful in their position. Various other statistical calculations were performed to draw the average force distance graphs for the positional categories for the peak torque variables. Furthermore the force distance graphs were assessed to determine the players’ ability to maintain 80% of peak torque. All the senior elite positional categories proved to be significantly (p < .05) older and heavier than the schoolboy forwards. The senior elite forward positional categories were also significantly (p < .05) taller than the schoolboy forward. There however proved to be no significant difference (p > .05) in stature between the backline and schoolboy forwards. All the positional categories proved to have significantly thicker (p < .05) necks, but significantly shorter (p < .05) cervical spines than the schoolboy forwards. The forward positional categories demonstrated to be significantly stronger (p < .05), on all peak torque measures, than the schoolboy forwards. The same was observed between the backline and schoolboy forwards, however no statistically significant difference (p > .05) was observed between the respective sample groups for the measure of peak lateral flexion left torque. For all the measures of power generated at 0.2 of a second, the senior forward positional categories proved to be significantly more powerful (p < .05) than the schoolboy forwards. The senior backline, although significantly more powerful (p < .05) in the flexion movement pattern, proved to be significantly less powerful (p < .05) than the schoolboy forwards in the lateral flexion right movement pattern. No statistically significant differences (p < .05) were found to exist between the senior backline and schoolboy forwards for the extension and lateral flexion left power generated at 0.2 of a second variables. All positional categories proved to have significantly smaller (p < .05) active and passive ranges of motion compared to the schoolboy forwards. Conversely, the senior elite players had significantly larger (p < .05) ratios (PTF/PTE, PTL/PTR, PT/BW and PT/LBM) than the schoolboy forwards. Literature has identified schoolboy rugby as having a much higher incidence of cervical spinal injuries than senior rugby. It can thus be inferred from the above information that the variables of peak torque and power generated at 0.2 of a second play a important role in safeguarding a player from injury on the field of play. Furthermore, calculated ratios show that senior players, especially the forwards, have undergone adaptive changes in cervical musculature strength to meet the requirements of the position they play in, thereby safeguarding themselves from cervical spinal injury. Proper cervical musculature conditioning has been cited in the literature as being an effective but neglected method of preventing cervical spinal injuries. The generation of normative data, concerning cervical musculature performance, can thus be used to prevent the occurrence of cervical injuries and re-injury of the cervical spine by providing a standard of musculature strength for safe participation in rugby, and possibly other collision type sports, and a quantified guide for successful patient rehabilitation respectively.

The front row positional category performed the best on the flexion power generated at 0.2 of a second variable (160.92 W). The front row positional category again achieved the largest extension power generated at 0.2 of a second average (237.02 W). The second row positional category achieved the largest lateral flexion right power generated at 0.2 of a second average (269.81 W). Similar results were observed with the measurement of lateral flexion left power generated at 0.2 of a second. The second row positional category achieved the largest lateral flexion left power generated at 0.2 of a second average (259.62 W). Again the backline players achieved the smallest power generated at 0.2 of a second averages for all the above-mentioned power variables. The measurement of passive (PROMFE) and active (AROMFE) range of motion for flexion to extension revealed that the second row had the largest average PROMFE (125.44°). The measurement of AROMFE revealed a similar result. The second row again had the largest average AROMFE (108.45°). The measurement of passive (PROMLF) and active (PROMFE) range of motion for lateral flexion left to right revealed smaller and different results to those found for PROMFE and AROMFE. For the variable of PROMLF the backline players had the largest average PROMLF (119.44°). Conversely, the second row had the largest average AROMLF (106.96°). The calculation of the various ratios revealed great variation between the positional categories. This can be attributed to the functional requirements the players have to adhere to, to be successful in their position. Various other statistical calculations were performed to draw the average force distance graphs for the positional categories for the peak torque variables. Furthermore the force distance graphs were assessed to determine the players’ ability to maintain 80% of peak torque. All the senior elite positional categories proved to be significantly (p < .05) older and heavier than the schoolboy forwards. The senior elite forward positional categories were also significantly (p < .05) taller than the schoolboy forward. There however proved to be no significant difference (p > .05) in stature between the backline and schoolboy forwards. All the positional categories proved to have significantly thicker (p < .05) necks, but significantly shorter (p < .05) cervical spines than the schoolboy forwards. The forward positional categories demonstrated to be significantly stronger (p < .05), on all peak torque measures, than the schoolboy forwards. The same was observed between the backline and schoolboy forwards, however no statistically significant difference (p > .05) was observed between the respective sample groups for the measure of peak lateral flexion left torque. For all the measures of power generated at 0.2 of a second, the senior forward positional categories proved to be significantly more powerful (p < .05) than the schoolboy forwards. The senior backline, although significantly more powerful (p < .05) in the flexion movement pattern, proved to be significantly less powerful (p < .05) than the schoolboy forwards in the lateral flexion right movement pattern. No statistically significant differences (p < .05) were found to exist between the senior backline and schoolboy forwards for the extension and lateral flexion left power generated at 0.2 of a second variables. All positional categories proved to have significantly smaller (p < .05) active and passive ranges of motion compared to the schoolboy forwards. Conversely, the senior elite players had significantly larger (p < .05) ratios (PTF/PTE, PTL/PTR, PT/BW and PT/LBM) than the schoolboy forwards. Literature has identified schoolboy rugby as having a much higher incidence of cervical spinal injuries than senior rugby. It can thus be inferred from the above information that the variables of peak torque and power generated at 0.2 of a second play a important role in safeguarding a player from injury on the field of play. Furthermore, calculated ratios show that senior players, especially the forwards, have undergone adaptive changes in cervical musculature strength to meet the requirements of the position they play in, thereby safeguarding themselves from cervical spinal injury. Proper cervical musculature conditioning has been cited in the literature as being an effective but neglected method of preventing cervical spinal injuries. The generation of normative data, concerning cervical musculature performance, can thus be used to prevent the occurrence of cervical injuries and re-injury of the cervical spine by providing a standard of musculature strength for safe participation in rugby, and possibly other collision type sports, and a quantified guide for successful patient rehabilitation respectively.

- Description: Research shows that maternal depression has adverse effects on mother-infant attachment and subsequent infant development (Cogill, Caplan, Alexandra, Robson & Kumar, 1986). The mechanisms through which this comes about are unclear. Murray & Cooper (1997) suggest an impaired pattern of mother-infant communication is responsible. Within this, Murray proposes that maternal speech may be a key factor. This study constitutes a preliminary exploration into the mechanisms through which maternal depression effects mother-infant interaction in South Africa. 147 predominantly Xhosa-speaking mother-infant dyads that took part in a broader epidemiological study on post-partum depression in Khayelitsha (Cooper, Tomlinson, Swartz, Woolgar, Murray & Molteno, 1999) made up the subjects. Maternal depression was assessed according to the Structured Clinical Interview for DSMIV (SCID). Maternal speech recorded from standard, five-minute, face-to -face mother-infant interactions was translated and analysed according to a coding system developed by Murray (Murray, Kempton, Woolgar & Hooper, 1993). The speech of depressed mothers to their two month old infants was compared to the speech of non-depressed mothers on dimensions of focus, affect and agency, and the role of infant gender was assessed. Results revealed no significant group differences for depression. Maternal speech to male infants was found to hold significantly less ascription of agency than to female infants. Findings suggest that maternal speech may be too narrow a marker of maternal depression in this context and that broader indices are needed. It is recommended that future research control for measures of social adversity, factor in cultural and language particularities, and consider contextual aspects of mother-infant interaction / attachment processes, in investigating the mechanisms through which post-partum depression leads to negative infant outcome in the developing world.

- Description: On July 29 2000, Uganda held a referendum to decide whether to continue with the ruling Noparty Movement system or to revert to the Multi-party platform. This research entails a qualitative content analysis of the role the media played in driving debate and understanding of the referendum and its role in the country’s democratisation process. The research is informed by Jurgen Habermas’s public sphere paradigm as well as the sociological theory of news production. The research covers Uganda’s two English dailies – The New Vision and The Monitor, examining whether they provided a public sphere accessible to all citizens and devoid of ideological hegemony. It concludes that the newspapers were incapable of providing such a sphere because of the structural nature of Ugandan society and the papers’ own capitalistic backgrounds and ownership interests. The research concludes that such English language newspapers published in a country with a low literacy rate and low income levels, can only provide a public sphere to elite and privileged sections of society. A case is then made that multiple public spheres would be better suited to represent the views of diverse interest groups.

This is true for all businesses and no less so in respect of family businesses. Balshaw (2003:23) lists the many issues which impede family businesses as, amongst others: Unresolved family and personal issues; Dysfunctional relationships; Poor communication; Lack of commitment; No succession plan or timetable; Inability of the senior generation to relinquish control; No unifying vision or dream in the family; Open conflict; Nonexistent decision-making and governance structures; Lack of transparency and openness; Failure to plan strategically. In addition to this the business must be aware of and react to the changing circumstances in the environment.

- Description: The development of standards for education and training is regarded as a very important activity by many countries. Any country that sets standards for education and training is trying to define its training system and avoid duplication of training by providers who do not see eye to eye. National standards are public documents accessible to anyone interested in education and training. Namibia introduced standards setting as a core activity of administering the National Qualifications Framework in 1996 after the passing of the Namibia Qualifications Act by parliament. This research attempts to gain an understanding of how the process of developing standards for the Life Assurance Sector in Namibia was managed by focusing on the experiences of three persons who took part in the process of developing the said standards. The case study approach enabled me to gain considerable insight into management issues that may have influenced the process of developing these specific standards. The findings illuminate the management and leadership issues which characterised the process for the LA Industry. Several management issues emerge as key elements in the process. These include: A strong emphasis on transformational leadership through clear vision crafting; empowerment through emancipatory thinking; OD features such as problem solving and effective communication; the importance of organisational structure; the concept of a learning organisation and benchmarking as well as collegiality. This research explores the relationship between management thinking generally, and the management of the standards development process in particular.

A generic simulation of energy consumption of automobile air conditioning systems

- Description: The air conditioning system in a car is, in addition to the heating system, installed to increase the comfort in the passenger compartment. Comfort is not the only reason for automotive air conditioning systems, as road safety also improves with the comfort of the driver, as a pleasant environment reduces driver fatigue. The rising environmental problems and, hence, resulting stringent legislation are forcing the automobile industry to develop cars with ever decreasing fuel consumptions. The question of better fuel consumption and energy utilisation does not stop with the engine and aerodynamics, but is required of the air-conditioning system as well. Thus, incessantly innovative technologies are developed to decrease the energy required by the air-conditioning systems. The interaction of the refrigerant cycle components and the rapidly changing operating conditions of the car (speed, revolutions per minute, etc.) places extensive demands on the control system. In addition, the air-conditioning system is also designed for high ambient temperatures (cool down), but is mostly used in fairly moderate conditions. This operation allows for energy saving control strategies such as externally controlled compressors, blower motor control, etc. The experimental comparison of different air-conditioning systems, components or control strategies is very time consuming and extensive, and the use of an air-conditioned wind tunnel is inevitable when experiments need to be done with reproducible ambient conditions.This, combined with the high costs of installation and operation of a wind tunnel is a major problem. Furthermore, the effect of component or control strategy enhancements should be available as soon as possible in the early stages of design. The above considerations have prompted the rapid development of new powerful simulation tools, but in most cases the simulation tools are focused on one specific component or problem only. A more holistic approach would be to combine the calculations of two or more programs. This implies the adaptation of the model to more programs which leads to a lack of transparency. Obviously, the entire development work cannot be done entirely by simulation, especially in the later phases of the development where it would still be necessary to build prototypes to evaluate the done work experimentally. However, in the early stages of development, it would be advantagous to work without expensive prototypes.

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

A review of the Kalahari group: an aid to Kimberlite exploration in this medium

- Description: The Kalahari Group sediments cover vast portions of the Archean Kaapvaal and Congo cratons that are considered highly prospective for economic kimberlites. In southern Africa, the term Kalahari refers to a structural basin, a group of Cretaceous to recent terrestrial continental sediments and an ill-defined desert, all of which have been grouped together as the Mega Kalahari by Thomas and Shaw (1993). The Mega Kalahari grouping includes sediments stretching from South Africa in the south to the Democratic Republic of Congo in the north, and from eastern Namibia to western Zimbabwe. This sand sea, at 2.5 million km², is the largest on earth and presents significant obstacles and challenges to the kimberlite explorationist attempting to locate bedrock-hosted diamondiferous kimberlite bodies. The Mega Kalahari sediments represent an ancient depositional environment with a complex history in which the stratigraphy and age of the deposits are not particularly well constrained or understood. Low fossil content, limited exposure, poor differentiation of the dominant surficial Kalahari Sand and a limited comprehension of an extensive duricrust suite has delayed the understanding of the sedimentological and environmental history of the basin. This sequence of sediments has accumulated and evolved through fluvio-deltaic, aeolian and groundwater processes, with characteristics due to primary deposition and subsequent modification being difficult to distinguish. Deposition in the Kalahari Basin has been subject to tectonic influences, changes in drainage directions and source areas of sediments, river capture and numerous large and small climatic fluctuations both in the basin and surrounding areas. It bears the imprint of recurring cycles during which the same sediments were reworked, sometimes by different agencies, all of which exacerbate attempts to correlate sedimentary units across the sequence. The Mega Kalahari is a series of contiguous Phanerozoic sedimentary basins situated within the African Superswell. The Superswell has dominated the gross geomorphology of southern Africa and contributed significantly to the present character of the Mega Kalahari and the evolution of the drainage systems. Overall, the tectonic framework established in southern Africa by the division of Gondwanaland led to the creation of a dual drainage system, with the hingeline acting as a watershed between a coastally-orientated exoreic system and an endoreic system draining into the interior. Deposition of sediments started in the late Cretaceous. Neo-tectonic activity expressed in the rifting in central Botswana, further influenced sedimentation rates and exerted a strong control over paleo-drainage directions. This revIew presents the complexities of the Kalahari cover sequence. The most Important geomorphological and sedimentary factors to be considered when designing and implementing kimberlite exploration programs within the Mega Kalahari environment are outlined and discussed. New data from exploration drilling programs are presented on the thickness of the Kalahari within portions of northern Namibia, western Zambia and Botswana. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The Superswell has dominated the gross geomorphology of southern Africa and contributed significantly to the present character of the Mega Kalahari and the evolution of the drainage systems. Overall, the tectonic framework established in southern Africa by the division of Gondwanaland led to the creation of a dual drainage system, with the hingeline acting as a watershed between a coastally-orientated exoreic system and an endoreic system draining into the interior. Deposition of sediments started in the late Cretaceous. Neo-tectonic activity expressed in the rifting in central Botswana, further influenced sedimentation rates and exerted a strong control over paleo-drainage directions. This revIew presents the complexities of the Kalahari cover sequence. The most Important geomorphological and sedimentary factors to be considered when designing and implementing kimberlite exploration programs within the Mega Kalahari environment are outlined and discussed. New data from exploration drilling programs are presented on the thickness of the Kalahari within portions of northern Namibia, western Zambia and Botswana. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This study explores the history of sex communication and education over a period of fifty years (1950 to the present), in a deep rural area of the Eastern Cape. It describes patterns of sex communication between peers, between siblings, between children and parents and between young people and other non-familial agencies within communities. Communication trends are traced from the period before contraception was introduced, through to the introduction of female birth control methods into the HIV/AIDS era where the focus has been on attempting to introduce condoms. Twelve semi-structured interviews and two four-person focus groups were conducted to gather information on how the participants acquired information about sexuality and their responses to the same. The findings of the present study suggest that the widespread use of injectable contraceptives has had a marked effect on the sexual culture of the community under investigation. It has led to the collapse of the regulatory practices which were previously in place. This in turn has significantly affected the sexual communication and negotiation context. Furthermore, it has had a determining influence on male involvement in sexual reproductive health matters and has created a poor context for the adoption of condoms as a prophylactic. There were no major changes in the sexual communication context within families and within communities in that education has always been limited to instructions to avoid pregnancy. Of note was a culture of collusion between adults and children surrounding sexuality, which absolved the parties involved in addressing sexuality. These factors are understood have mediated response to HIV/AIDS prevention efforts, and need to be taken into consideration in the development of sex communication and education programmes.

A study of the powers of the Swazi monarch in terms of Swazi law and custom past, present and the future

- Description: The thesis covers the branches of law known as Constitutional law and Customary law. It focuses on the powers of the Swazi monarch, which are based on a combination of the received Western law and Swazi custom. For the purposes of this study, therefore, Swazi law and custom shall be taken to include both the statutory law and the yet unwritten customary law. Swaziland is black Africa's only remaining traditional monarchy, ruled as it is by the Ngwenyama, an indigenous institution, whose origin is derived from custom. The resilience of this ancient system of government in a continent where modernisation and constitutional democracy among other factors have led to its extinction is phenomenal, particularly because some commentators have described traditionalism in modern Africa as an "embarrassing anachronism.' In Swaziland the monarchy continues to be a vibrant system and the nation is currently engaged in a process of not only codifying the customary law but also of drafting the constitution of the country. One of the key areas of concern is the question of the distribution of power between the monarch and the people under the proposed constitution. Traditionalists are of the view that the powers that the King currently exercises should remain intact as they are a reflection of the Swazi law and custom. Progressives, on the other hand, are of the view that the current position makes the King an absolute monarch and are thus proposing a change from an absolute to a constitutional monarch. In other words they want some kind of checks and balances in the envisaged system of government. The study will show that the constitutional evolution of Swaziland and the exigencies of synthesising modern and traditional systems of governance have over the years obscured the true nature of the powers of the monarch in terms of Swazi custom. Thus before we can consider whether the future of the monarchy in Swaziland depends on the harmonisation of modern and traditional systems of governance, it is necessary to revisit the past to determine the powers of the monarch in their embryonic form, for it is from this period that we can extrapolate the powers of the Ngwenyama in terms of Swazi custom. The thesis has been arranged as follows: The first chapter will review the precolonial political system of Swaziland with a view to establishing whether monarchical authority was founded on command or consensus. The various theories, which seek to explain the foundations of the monarchical system of government, will be outlined. The second chapter will focus on European influence on the Swazi traditional system of government. The third chapter will be an analysis of the powers of the monarch under the 1968 independence constitution. The fourth chapter will focus on the effect of the repeal of the 1968 independence constitution by the Monarch. The fifth chapter will focus on the constitutional reforms under the reign of king Mswati III. The sixth and last chapter focus on proposals for reform. The research method used was in the main, an analysis of relevant legal principles as contained in textbooks, legislation, journals, the scant case law that is available in this area of the law and other relevant materials. A comparative survey of ancient African kingdoms will be done, with emphasis on those Kingdoms, which later became British colonial possessions. It is hoped that this comparative analysis will help explain the evolution of these traditional structures alongside modern governmental institutions.

- Description: A number of outcrops of the Witteberg Group and lowermost Karoo Supergroup rocks were studied in the area south of the Darlington Dam, Jansenville District, with the aim of documenting structural characteristics of the area. All lithologies are folded with fold styles varying from gentle to near isoclinal (based on interlimb angle). Fold axes are either sub-horizontal or plunging at gentle to moderate angles whereas axial planes dip gently to vertically (predominantly steep to sub-vertical). Folds verge predominantly towards the north but where southward verging they are associated with faulting or strongly folded areas. Folds plunge gently to the east-southeast and west-northwest. The area consists of a large anticlinorium with both first and second order folds occurring. Eastwest striking faults occur in the study area and are classified as normal, reverse and thrust faults. A study of the joint sets shows that there are four dominant joint directions, namely 18o, 33o, 97o and 107o (in order from least to most important). An interpretation of the tectonic history is presented in which the relationships between faults and folds show that faults formed during and after folding. Folding, and reverse and thrust faulting, occurred during the compressional events that formed the Cape Fold Belt, whereas the normal faults formed during the relaxation of these compressional forces or during the break-up of Gondwana.

- Description: This research reports on two action research case studies of participatory materials development in two rural community contexts in Zambia, namely Chiawa and Nalusanga. It aims to explore and articulate the relationships between community-based environmental education and participatory materials development in the WWF Zambia Education Project context; clarify participatory materials development processes by identifying the roles of different ‘actors’ in these processes and identify and analyse the contextual and other factors that may influence development and use of environmental education materials in rural communities. These aims were explored by means of a number of action research cycles of inquiry in the two communities. The study also articulates the significance of considering ambivalent globalising influences such as international conferences, debates, overseas development aid, national policies and how these shape and influence materials development work in a local context. In order to gain more insight into the local contexts, I developed contextual profiles on the two communities. These capture the contextual factors that influenced the participatory materials development processes. They include issues such as language, ethnicity, literacy, power relations and the local social economy, amongst others. Although this study has been predominately guided by the socially critical orientation to research and education, I have drawn on aspects of other research orientations. I have also explored some of the emerging critiques of the socially critical orientation. The findings of this study reveal the different roles participants can play in participatory materials development; participatory materials development processes as a learning process; the dynamics of participation in an African context; the role of language and literacy in materials development; the need for open-ended process models of learning amongst adult learners and the importance of merging expert and local knowledge in participatory materials development. This study opens up possibilities for further exploration of participatory materials development processes within the WWF ZEP context and beyond.

- Description: Photojournalism in South Africa is in the process of undergoing a shift from an analogue past to a fully digital future. This shift to digital has already been completed by many of the newspapers in the United States of America and Europe, and the new technology is seen to have made fundamental differences in the way that journalists do their job. This thesis attempts to explore the differences brought about, as well as the problems experienced by the photographic department at the Sowetan newspaper as a result of the shift to digital. How the development of technology has affected the photojournalist throughout is focused upon in a brief history of photojournalism and examples of how technology has shaped different aspects of journalism in both a positive and negative manner is considered. Exactly what digital photography is, how it has been integrated into American Photographic departments and the changes that the new technology has prompted are also explained. The manipulation of images in the past as well as the relative ease of digital manipulation are covered and concerns are raised about the future implications of digital manipulation. By conductlng participant observation and holding interviews, research data was compiled which allowed conclusions to be drawn about the impact that the shift to digital had had on the Sowetan photographic department. Intentional and unintentional consequences were expected and revealed in the research. The job of the photojournalist and photographic editor was found to have changed but perhaps not as dramatically as expected. Third world factors such as crime, poverty and lack of education were discovered to have resulted in problems that differed noticeably from those experienced by American and European photographic departments. Some expected difficulties were not experienced at all, while other major obstacles, specifically the repairs that must constantly be made to the digital cameras, continue to hamper the operations of the new digital department. Some understanding of the problems that might be encountered by future photojournalism departments that are considering making the shift to digital are arrived at, in the hope that they may be foreseen and overcome.

- Description: The research problem addressed in this study was concerned with the identification of factors that inhibit Small and Medium Enterprises from exporting their products to South Africa’s most important trading partners. To achieve this objective, a theoretical study was conducted to establish what literature reveals to be the most important trading partners, and the problems which businesses experience when they export their products to these destinations from the Eastern Cape. The information obtained in the literature study was analysed, and, in order to resolve the main problem, the research questionnaire was divided into four parts. • Part 1 consisted of biographical questions. • Part 2 consisted of questions aimed at establishing the reasons why organisations embarked on exporting. • Part 3 was concerned with what the respondents perceived as barriers to their export operations. • Part 4 was concerned with strategic decisions and the minimising of risk. The empirical results obtained indicate that, although inhibiting factors are a reality in exporting, these remain secondary to general market forces of supply and demand. It was shown that inhibiting factors do not play as big a role in the export process as the literature suggests.

- Description: Body-In-White business forms part of the automotive industry. The industry is highly specialized and usually operates under tremendous pressure due to the competition within the industry as a result of an oligopolistic market, limited resources, short lead times and the contractual nature of the industry. The selected business has grown steadily over the last five years in terms of the number of employees that have been employed. It is said that employees are a business’s most important asset. How effectively a business is managed during growth and the relationship management has with the employees during that period are critical to a business in maintaining a competitive advantage. Effective management and sound employee relations could ensure the longterm profitability and sustainability of the business. This paper is intended to analyse the selected business to determine how effectively the business is managed and the state of employee relations within the business. Various aspects to effective management and employee relations are presented through a literature study in order to identify the means required to manage effectively and to promote and maintain sound employee relations. A two-pronged approach was undertaken in the applied research. Firstly, a survey with the aid of a structured questionnaire was undertaken among the management of the selected business to gather information. A second survey also with the aid of a structured questionnaire was undertaken among all the employees. The purpose of the two different questionnaires was to make an analysis of the business and to determine whether management and the employees held the same views, or differed on related topics. Mostly management indicated that managerial effectiveness is critical to remaining competitive. Employees indicated that management does not plan and organise an orderly workflow and that employees rely on their overtime remuneration. There was a general agreement by management and employees that more than one person attends to human resource related issues. Effective human resource planning is not enforced to maintain a motivated workforce, as human resource policies and procedures do not pay special attention to employee relations. Among the main findings, the study revealed that while there are some aspects of effective management lacking in the business, the business is mostly managed effectively. However, not enough attention is paid to effective human resource management, as training and development programs for management and employees are lacking and certain human resource issues need to be addressed.

This paper is intended to analyse the selected business to determine how effectively the business is managed and the state of employee relations within the business. Various aspects to effective management and employee relations are presented through a literature study in order to identify the means required to manage effectively and to promote and maintain sound employee relations. A two-pronged approach was undertaken in the applied research. Firstly, a survey with the aid of a structured questionnaire was undertaken among the management of the selected business to gather information. A second survey also with the aid of a structured questionnaire was undertaken among all the employees. The purpose of the two different questionnaires was to make an analysis of the business and to determine whether management and the employees held the same views, or differed on related topics. Mostly management indicated that managerial effectiveness is critical to remaining competitive. Employees indicated that management does not plan and organise an orderly workflow and that employees rely on their overtime remuneration. There was a general agreement by management and employees that more than one person attends to human resource related issues. Effective human resource planning is not enforced to maintain a motivated workforce, as human resource policies and procedures do not pay special attention to employee relations. Among the main findings, the study revealed that while there are some aspects of effective management lacking in the business, the business is mostly managed effectively. However, not enough attention is paid to effective human resource management, as training and development programs for management and employees are lacking and certain human resource issues need to be addressed.

- Description: More and more organizations are making use of teamwork. Effective teams are also important from an Information Technology (IT) perspective, since teamwork forms an integral part of all software development activities. It is therefore extremely important that IT students are able to work together as an effective team. These statements lead to the following questions – How can IT student project teams be effective and what obstacles need to be overcome in order to ensure effectiveness? This dissertation reports on an exploratory study of second and third year IT project teams and exposes factors that lead to ineffectiveness. Firstly, the problems experienced by the groups seem to have the largest detrimental effect on effective team functioning. Secondly, the project mark is also affected by the priority issue that is associated with the particular task. Thirdly, the issues of time management, communication, conflict management, compromise, social loafing and group cohesion also play an important role in team effectiveness. This dissertation sets out to prove that the key to "effectiveness" lies in empowering the student to deal with all possible dilemmas that may be faced when working in teams in the tertiary team situation. The benefits of these actions will hopefully lead to the realization of “effectiveness” in the tertiary team situation and ultimately, in the student’s work environment.
