- 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.

- 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: This research was carried out in order to gain a better understanding of the practice of governance in a technical or vocationally oriented college and the critical role played by the principal as a college manager within the governance system in which industrialists and head office are also key players. Conceptual literature relating to issues of governance and management within the education scenario is examined. The wider issues of governance are critically analysed in the context of power and control mechanisms initiated by the Ministry of Higher Education as the responsible authority for the colleges. The influence of the industrial sector as the consumers of skilled labour force is analysed through college advisory councils set up in terms of the relevant pieces of legislation. The research is qualitative and takes the form of three case studies of technical and vocational colleges in Zimbabwe. Data were collected through multiple methods from varied sources with a view to ensuring triangulation. The multiple-case design enabled me to dig beneath the surface of what apparently happens in these organisations and unearth issues and concerns at the wider governance and management levels. Views and experiences of participants are captured and explained through in-depth interviews, observations and documentary sources. Results are discussed in relation to the relevant literature allowing grounded theory to emerge. The research highlights the roles of key players in governance and the issues of relationships among these actors. What emerges is a desperate situation of ineffectiveness, problematic processes in governance and poor responsiveness of these colleges to the labour market demands. The potential for generalisability and transferability is discussed in the report and possible corrective intervention strategies are recommended. The thesis demonstrates that managers of these colleges and indeed senior officers in head office who are at the centre of governance and will need transformational leadership development in order for them to come to terms with such things as people’s feelings, abandoning ‘outdated’ policies, managing change, and handling communication effectively. Various strategies for revitalisation of governance and management in technical and vocational colleges are suggested.

- 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.

- Description: A business needs to be dynamic and adjustable to survive in the ever-changing marketplace in which it operates. The environment is no longer merely the immediate domestic business environment within which the specific business operates but also, with the advent of information technology and globalisation, overseas markets. 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: A business needs to be dynamic and adjustable to survive in the ever-changing marketplace in which it operates. The environment is no longer merely the immediate domestic business environment within which the specific business operates but also, with the advent of information technology and globalisation, overseas markets. 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.

- 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.

- Description: Owners and vendors are increasingly publishing their materials in digital form. Because such materials can be exactly copied, a mechanism is required that will protect the legitimate owners of these works, by providing proof of original ownership. Digital watermarking has now become one accepted method of establishing ownership of digital materials. The owner of a work embeds a pattern, called a digital watermark, in the content. This embedded watermark is normally undetectable, but its presence can be demonstrated by the owner of the work or his agent, thereby proving ownership. Digital watermarking has been used for many types of multimedia content, primarily audio, video and flat images. Recently, interest has been shown in applying digital watermarking schemes to 3D surfaces, in various formats. In this paper, we examine a method whereby a digital watermark can be embedded in a Bezier surface. A prototype watermarking method for such surfaces is presented, with some experimental results, and a discussion of directions for future research.

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: Multimedia applications today make use of virtual humans. Generating realistic virtual humans is a challenging problem owing to a number of factors, one being the simulation of realistic hair. The difficulty in simulating hair is due to the physical properties of hair. The average human head holds thousands of hairs, with the width of each hair often smaller than the size of a pixel. There are also complex lighting effects that occur within hair. This paper presents a LightWave 3D plug-in for modeling thousands of individual hairs on virtual humans. The plug-in allows the user to specify the length, thickness and distribution of the hair, as well as the number of segments a hair is made up of. The plug-in is able to add hairs to a head model, which the user then modifies to define a hairstyle. The hairs are then multiplied by the plug-in to produce many hairs. By providing a plug-in that does most of the work and produces realistic results, the user is able to produce a hairstyle without modeling each individual strand of hair. This greatly reduces the time spent on hair modeling, and makes the possibility of adding realistic long hair to virtual humans reasonable.

- Description: This thesis describes the development and application of a neural network based ionospheric model for the bottomside electron density profile over Grahamstown, South Africa. All available ionospheric data from the archives of the Grahamstown (33.32ºS, 26.50ºE) ionospheric station were used for training neural networks (NNs) to predict the parameters required to produce the final profile. Inputs to the model, called the LAM model, are day number, hour, and measures of solar and magnetic activity. The output is a mathematical description of the bottomside electron density profile for that particular input set. The two main ionospheric layers, the E and F layers, are predicted separately and then combined at the final stage. For each layer, NNs have been trained to predict the individual ionospheric characteristics and coefficients that were required to describe the layer profile. NNs were also applied to the task of determining the hours between which an E layer is measurable by a groundbased ionosonde and the probability of the existence of an F1 layer. The F1 probability NN is innovative in that it provides information on the existence of the F1 layer as well as the probability of that layer being in a L-condition state - the state where an F1 layer is present on an ionogram but it is not possible to record any F1 parameters. In the event of an L-condition state being predicted as probable, an L algorithm has been designed to alter the shape of the profile to reflect this state. A smoothing algorithm has been implemented to remove discontinuities at the F1-F2 boundary and ensure that the profile represents realistic ionospheric behaviour in the F1 region. Tests show that the LAM model is more successful at predicting Grahamstown electron density profiles for a particular set of inputs than the International Reference Ionosphere (IRI). It is anticipated that the LAM model will be used as a tool in the pin-pointing of hostile HF transmitters, known as single-site location.

- Description: mLAN is a networking technology based on the IEEE 1394 standard that allows for the transport of audio and music control data between audio devices. In the original implementation of mLAN, software within each mLAN node hosted by an audio device contained high level plug abstraction and connection management software. mLAN-B is the next generation mLAN architecture that splits the connection management function between workstation and device. The high level connection management and plug abstraction capability resides on the workstation, while a thin low level connection management capability is left on the device. This approach reduces cost and complexity on the device side and ensures that mLAN systems can be easily upgraded.

- Description: In recent years the World Wide Web has transformed into a dynamic, interactive medium, exposing a proliferation of on-line services that dis-tribute large quantities of multimedia. This has increased awareness of the need to select an appropriate Web programming technology when creating Webbased services. This paper compares three dynamic Web programming technologies from the point of view of performance in multimedia distribution. In particular, this paper examines Sun Microsys-tem’s Java Server Pages (JSP), Microsoft’s Active Server Page’s (ASP) and the more recent ASP .NET. The comparison is based on testing applications that distribute multiple images from an Oracle 9i database to Web-enabled clients. Previous research conducted by Oracle indi-cates that JSP and the underlying Java platform outperform ASP. The results in this paper, however, do not agree with Oracle’s statement as JSP tends to be marginally slower than ASP.

- 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.

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.

- Description: This research sets out to examine how entrepreneurs experience and deal with ethical dilemmas. An entrepreneur is defined as a person who creates something of value and assumes the risk of establishing and managing a business around it. An ethical dilemma comes about when the entrepreneur must choose between alternatives and where the morally correct choice is unclear. This may be due to conflicting personal values or loyalties, tensions arising out of the realization that the moral action is not in line with his self-interest, cross-cultural conflict, or moral ambiguity. Because of the nature of entrepreneurship, the entrepreneur typically lives with ever-present threats arising from limited resources, competition, and the risk of business failure. His actions must simultaneously ensure survival, maximize profit, limit risk, counter threats, optimize the use of resources, and reward him with a feeling of satisfaction. It is hardly surprising that conflicting priorities sometimes ensue. It is also widely believed that these entrepreneurial pursuits supersede the more general need to act in morally appropriate ways. This is a phenomenological study, based on interviews with seven entrepreneurs in established service-oriented ventures. They were asked to describe their business, any dilemmas they have experienced, how they were handled, and what challenges they experience as entrepreneurs in South Africa today. Using phenomenology as my vehicle for data collection and analysis, I sought to enter the lived-worlds of my participants to discover the essence of how ethical dilemmas are experienced in the entrepreneurial milieu. The study’s findings reflect that each entrepreneur has a distinctive world-view, which is represented by a complex mosaic of virtue ethics, deontology, utilitarianism and metaethical perspectives. The permutations are numerous, thus negating the possibility of typecasting entrepreneurs. Instead this research introduces the reader to aspects of entrepreneurial reality such as the complexity of cultural diversity, the freedom to limit the amount of personal energy given to business, and the existence of a more sensitive, searching inner soul beneath the apparent hard-nosed business-oriented public image. While examining entrepreneurial dilemmas in depth, this research introduces the dilemma drum as a tool to portray the argument form of any dilemma by making explicit the ethical component inherent in every business decision and facilitating its effective resolution in a non-prescriptive way. The findings identify certain individual characteristics of participant entrepreneurs that are unlike anything in the mainstream literature, dispelling notions of the entrepreneur as a societal misfit, an essential innovator with vision and flair, or a compulsive risk-taker, while confirming success as the key motivator rather than money per se, the importance of significant others, and the influence of culture and gender. They provide fresh insights into the psyche of the entrepreneur, which include: the existence of inner conviction - marrying the concept of goal-directedness with that of making a contribution to society; exercising the virtues in order to support a delicate balance between business and ethical imperatives; learning to respect energy flow; an alternative morality based on attracting and allowing benevolent or serendipitous events to happen naturally and redefining success as ‘being able to create what is needed as and when needed’; focusing one’s energy on the telos; developing a personal marketing formula suited to a culturallydiverse society; and the anxiety associated with being out-there on one’s own. The general statement, which is ultimately distilled from the seven situated descriptions, introduces a theory of entrepreneurial ethics that presents a new and different view of the lived-world of entrepreneurship, consisting of: Firstly, the key components of entrepreneurial success – having clear goals, energy, making a contribution to society, being connected, getting others on board, and work as an extension of self; secondly, what drives entrepreneurs – goal-orientation, sense of personal excitement, inner conviction, autonomy, and external recognition of success; thirdly, the entrepreneurial ethic – concern for credibility, commitment to service, contributing to quality of life; fourthly, the nature of entrepreneurial dilemmas - conflicting responsibilities, authenticity and credibility, risk and expansion, and awareness of diversity; fifthly, how entrepreneurs deal with ethical issues in their own distinctive ways – by holding fast to authentic virtues, bowing to community expectations, avoiding friction, adopting a ‘come-what-may’ or ‘what’s in it for me’ attitude, or pursuing a higher purpose where both parties benefit; sixthly, entrepreneurs’ world -views – beliefs, goals, ways of deriving satisfaction, virtuous behaviour; pen-ultimately, the challenges facing entrepreneurs in South Africa – overcoming the legacies of apartheid, containing crime, fostering an acceptable business ethic, and facilitating reconciliation between ethnic groups; and lastly, finding the power within – that illusive entrepreneurial spirit – self-reliance, looking beyond immediate obstacles, grasping opportunities, and understanding serendipity.

- Description: Every country has weed species whose presence conflicts in some way with human management objectives and needs. Resources for research and control are limited, so priority should be given to species that are the biggest problem. The prioritization system described in this article was designed to assess objectively research and control priorities of invasive alien plants at a national scale in South Africa. The evaluation consists of seventeen criteria, grouped into five modules, that assess invasiveness, spatial characteristics, potential impact, potential for control, and conflicts of interest for each plant species under consideration. Total prioritization scores, calculated from criterion and module scores, were used to assess a species' priority. Prioritization scores were calculated by combining independent assessments provided by several experts, thus increasing the reliability of the rankings. The total confidence score, a separate index, indicates the reliability and availability of data used to make an assessment. Candidate species for evaluation were identified and assessed by several experts using the prioritization system. The final ranking was made by combining two separate indices, the total prioritization score and the total confidence score. This approach integrates the plant's perceived priority with an index of data reliability. Of the 61 species assessed, those with the highest ranks (Lantana camara, Chromolaena odorata and Opuntia ficus-indica) had high prioritization and high confidence scores, and are thus of most concern. Those species with the lowest ranks, for example, Harrisia martinii, Opuntia spinulifera and Opuntia exaltata, had low prioritization scores and high confidence scores, and thus are of least concern. Our approach to ranking weeds offers several advantages over existing systems because it is designed for multiple assessors based on the Delphi decision-making technique, the criteria contribute equally to the total score, and the system can accommodate incomplete data on a species. Although the choice of criteria may be criticized and the system has certain limitations, it appears to have delivered credible results.

A qualitative analysis of the need-satisfying experiences of the customers of a niche-restaurant

- Description: Tradition dictates that marketing decision-makers remain accurately aligned with the dynamic and vacillating need structures of the target markets they serve. To comply with this caveat, a time-honoured and largely unchallenged philosophy of customer orientation has been applied. Theory further strongly contends that if such a business stance is vigilantly and diligently applied, any firm is bound to gain a competitive edge in the market place. A weakness in the above marketing mindset is the perception that when a spectrum of business elements are orchestrated and focussed on customers, target audience members will automatically be satisfied and return their patronage. This so-called marketing concept has undergone major reevaluations over the past decades, and it is now becoming ever more prevalent to witness varied permutations of new marketing architecture evolving in literature and practice. The unit of analysis selected for this research study is a niche restaurant that flouts many of the rudimentary traditional rules of marketing and iconoclastically succeeds despite all counter-logic. What such organisations have been practicing, albeit unknown to themselves, is a new way of business - a stance that has only recently been taken seriously by academics, writers and marketing professionals. These intuitive marketers are succeeding in niche businesses, despite going against the tide of the ingrained paradigm mindsets of conventional marketing stalwarts. Such niche business people have discovered is that there is more to satisfying consumer needs than simply honing in and understanding what the basic needs of designated audiences are. A growing band of new age marketers have been challenging orthodox marketing philosophy. Tofler, the visionary futurist, alluded to a host of unarticulated psychic consumer needs that would emerge as society drifted into a clinical and dispassionate ‘new’ millennium. In a world geared to instant gratification, fast-paced living and mechanistic social interactions, jaded consumers seek recognition as individuals (Tofler, 1970). They quest for inclusion rather than exclusion. They need a place to feel safe and find solace. Hence, it is now clear that simply attempting to satisfy the fundamental dimensions of consumers’ needs is no longer sufficient. Consumers rather seek the fulfilment of an holistic band of experience dimensions. Increasingly, phrases such as “winning consumer hearts and minds” are entering the vocabulary of marketers on a regular basis. The present vogue is to isolate and then include a range of intangible elements that are embodied in the process of satisfying customers needs. However, despite a growing awareness of the significance of mental-need satisfiers, in the specific domain of this investigation there is sparse evidence in literature of the mechanics of such novel thinking. The study unit is a second generation restaurant where many of the hollowed cornerstones of conventional marketing are inadvertently flouted. Different sets of rules of engagement seem to apply to their customers, who are also their most ardent advocates. A unique philosophy and business ethos also appears to prevail. In the study, the idiosyncratic characteristics which socially and competitively differentiate such a business were identified, explored and expiated. The constituents were then harmonised in an effort to establish what ‘it’ was that magnetically attracted patrons back despite the owner’s unintentional dismissive predisposition towards fundamental theory. As a result of this in-depth qualitative study, an holistic model encompassing all of the dimensions of a dining out experience at a niche restaurant have been proposed. Consequently the pillars upon which a sustained, enduring, loyal staunch customer base can be bed-rocked have been identified. Further, for the study unit, a typology of its diner corpse has been developed. The owners of the establishment under investigation have succeeded to provide an intimate family haven for their patrons. They, and their diners have collectively given strong, descriptive voice to the psychogenic need satisfying elements that have always existed, but to date have been unarticulated and unrecorded. This thesis brings the milieu of the iconoclast niche restaurant marketing practitioner to life.
