Description: During the 1990’s many South African companies experienced the need to change and adapt. This was largely because of the environmental changes brought about by a new political regime. One of these changes was the exposure of South African companies to global competition. Because the South African business environment had remained relatively static during the 1980’s, many companies had no idea of how to manage change when it became necessary for economic survival. This inability led to the demise of many organisations. As change as a business concept covers a vast area, the main objective of this study was to isolate one area of change and examine it in a practical context. The chosen area was the relationship, if any, between strategy and organisational structure. The practical context chosen was an organisation, which had recently undergone strategic change. The research methodology for this study included the conducting of an intensive literature study, to determine the academic stance on the strategy/structure relationship. Various academic theories were examined to determine whether there was a relationship between the two concepts, and if so, what the relationship should be. This provided a background for the practical evaluation. Literary opinion showed consensus that there was indeed a relationship between the two; in fact the one was integral to the success of the other. That is, if an organisation chooses to consider adopting a change strategy, it should carefully consider its impact on organisational structure. To summarise, in a situation of change, structure should support strategy to ensure a successful transition. An empirical study was then conducted at Pennypinchers (Pty) Ltd , which had recently undertaken to implement a change strategy. The focus of the empirical study was the relationship between the chosen change strategy and organisational structure.

Description: publisher version , Environmental policy development and implementation has become a ‘hot topic’ in southern Africa, following global imperatives for countries around the world to articulate their intentions to become more sustainable through public policy. Many policies in the region have been developed with the support of large scale donor funding. Much of the funding is often allocated to policy development processes rather than policy implementation processes, and many countries have experienced ‘gaps’ between policy intention and policy playing out in the field. Recently the Southern African Development Community’s Regional Environmental Education Programme (SADC REEP) appointed an environmental education policy advisor to influence regional policy (our Guest Editor, Charles Obol).This edition of the journal, funded by SADC REEP, aims to provide perspective on the policy-in-practice nexus in southern Africa.

Description: Thermal responses were measured in cicadas collected in the Eastern Cape Province of South Africa. The thermal responses of 22 species from 5 biomes were determined. Shade-seeking temperature was the most variable and related to the various biomes. Mean shade-seeking temperature was greatest for species inhabiting the thicket biome and lowest for species inhabiting the forest biome. The animals that live in the thicket biome may adapt to the greater thermal stress to take advantage of a habitat that permits lower predation pressure. There is a correlation between body size and shade-seeking temperatures with smaller species exhibiting lower thermal responses within a particular habitat. This may be related to the greater heat exchange in smaller species. Heat torpor temperatures did not differ between the various biomes.

Description: This study focuses on entrepreneurs within the SME sector using large format digital printing (LFDP) because of the changes in technology that influences the decisionmaking processes of the entrepreneur in the purchasing of a new LFDP. These fast changes are likely to continue and can cause technologies to become obsolete overnight. The entrepreneurs within the LFDP industry find themselves in the midst of these fast changes and are faced with a dilemma. On the one hand, they need to make sure that the technology used produces consistent and quality products. On the other hand, the entrepreneur needs to ensure an optimal return on investments. From the literature and the findings of the study, the researcher recommends a change to an existing model on a consultant involvement purchase of high technology products, which is then adapted to integrate resource-forecasting areas together with timing and type of information required as well as external environment scanning. The existing model’s focus is on the individual’s ability to make decisions based on their own knowledge. However, by integrating technology forecasting components, and scanning the business environment and resource forecasting needed the decision-maker will be better equipped to make decisions that also takes into account the external environment. This will also allow them to plan and manage growth in a systematic way. Therefore the proposed model takes into account individual capabilities and technology forecasting components that can facilitate the decision-making process. The adapted model on decision-making clearly delineates that the combination of entrepreneurial qualities and technology forecasting techniques in the LFDP industry will ultimately assist the entrepreneur on various levels in deciding on a new LFDP.

Description: An in depth chemical investigation of the major and minor pyrroloiminoquinone metabolites produced by four species of endemic South African Latrunculid sponges, collected from Algoa Bay and the Tsitsikamma Marine Reserve off the south eastern coast of South Africa, yielded eleven new and twelve known pyrroloiminoquinone metabolites. The structures of the new metabolites were determined using standard spectroscopic techniques. Tsitsikamma pedunculata was shown to contain 7,8-dehydro-3-dihydro-discorhabdin C (2.1), 14-bromo-7,8-dehydro-3-dihydro-discorhabdin C (2.2), discorhabdin S (2.3), 14-bromo-1-hydroxy-discorhabdin S (2.4), 1-bromo-2-hydroxy-4-debromo-discorhabdin S (2.5), and 2,4-debromo-3-dihydro-discorhabdin C (2.6), together with the known compounds 14-bromo-discorhabdin C (1.51), 14-bromo-3-dihydro-discorhabdin C (1.52) and 3-dihydro-discorhabdin C. The metabolites from T. pedunculata were characterised by the presence of a reduced C-3 carbonyl and bromination at C-14. Compounds isolated from a second Latrunculid sponge, Latrunculia lorii, ranged from a substituted bicyclic pyrrolecarboxylic acid, makaluvic acid A (1.47), to the simple tricyclic known pyrroloiminoquinones makaluvamine C (1.33) and damirone B (1.20) and the more complex discorhabdin D type metabolites, discorhabdin M (3.2), 1-amino discorhabdin D (3.3), 1-methoxy discorhabdin D (3.4) and 1-alanyl discorhabdin D (3.5). Discorhabdin G* (3.1) was also isolated and characterised. This is the first reported occurrence of the known compounds 1.20, 1.33 and 1.47 in a Latrunculia sponge. Discorhabdin and bis-pyrroloiminoquinone type compounds predominated in Tsitsikamma favus. Three known, tsitsikammamines A (1.71) and B (1.72), 1.52, and five new pyrroloiminoquinones, tsitsikammamine N-oxime (4.1), tsitsikammamine B N-oxime (4.2), 2.1, 2.4 and 2.6, were isolated from this sponge. A fourth Latrunculid sponge (Strongylodesma sp.) yielded three known compounds, discorhabdins A (1.57), D (1.61) and 1.53, and one new pyrroloiminoquinone 3.3. The dual role of these metabolites as cytotoxic agents and pigments resulted in an attempt to relate the photochemical properties of these metabolites to their cytotoxicity. The pyrroloiminoquinone metabolites studied exhibited moderate singlet oxygen quantum yields, while three compounds (1.57, 4.1 and 4.2) were shown to be capable of producing radicals at a wavelength of 532 nm. The possibility of a correlation between the electrochemical properties and anti-cancer (HCT-116) activity of selected pyrroloiminoquinones was explored. A study of the oesophageal and ovarian cytotoxicities of two pyrroloiminoquinones (1.57 and 1.72), together with an investigation into the intercalation and topoisomerase I inhibitory activity of the bis-pyrroloiminoquinones (1.71, 1.72, 4.1 and 4.2), are presented.

Description: Quality-of-life studies are ideally suited to fulfilling the new international youth research agenda, which focuses on ‘positive youth development’ to make recommendations for policy and practice. The paper reports a South African case study conducted among disadvantaged youth for this purpose. A sample survey of close on 900 African youth, aged 15-24 years, sought to identify indicators of positive development to serve as goals of youth and community work in Grahamstown East/Rini, in the Eastern Cape province of South Africa. The setting is unique. This mainly rural province is among the poorest, least developed, and has one of highest unemployment rates. Nevertheless, Grahamstown may offer special development opportunities for local youth due to the proximity of the city centre and diverse extension projects for youth. The survey found that development opportunities were unequally distributed with the materially advantaged youth being more exposed to development opportunities through their schools, spare time activities, and community contacts. They were more ambitious than others and more aware of risks facing contemporary youth. Advantaged youth also reported higher levels of subjective well-being and optimism, findings consistent with earlier studies conducted among adult populations, which report remarkable congruence between material and subjective well-being among South Africans. The analysis used overall life satisfaction as key indicator of successful youth development to learn more about major youth aspirations and goals. In conclusion, the study was able to identify a youth development initiative based on the aspirations of the youth, which might be pursued as a researcher-practitioner partnership project in line with the new international youth research agenda.

Description: [From the introduction]: Most male cicadas produce a calling song in order to attract conspecific females. These songs have been shown to differ in closely related species (e.g. Alexander & Moore 1962; Villet 1988, 1989; Boulard 1995; Marshall & Cooley 2000; Sanborn & Phillips 2001) and in species which share habitats (e.g. Sueur 2002). The former is an inevitable part of the divergence of recognition signals that characterizes the speciation process in animals using acoustic signals (Villet 1995), while the latter would be expected from a signal that acts as a reproductive isolating mechanism (Claridge 1985; Marshall & Cooley 2000). Calling songs are therefore of value in resolving taxonomic problems in the cicadas.

Description: It is beyond debate that each job lost due to restructuring means a lost taxpayer, and hence lost tax revenue, more poverty and increased crime. South Africa and the world at the large have to deal with this problem head – on in view of the acute need to better the lives of people and encourage investment. Technological advancement should be embraced and used to benefit people and stimulate economies, and that is further challenge in its own right. In Chapter 8 of the White Paper on Transformation of the Public Service dated 15 November 1995 (hereinafter, the White Paper), it is said that: “The Government of National Unity has embarked upon a concerted and comprehensive programme of administrative restructuring and rationalisation (my emphasis) with the object of: (a) Creating a unified and integrated service. (b) Creating a leaner and more cost-effective service.” Various strategies are listed in the White Paper, and the fundamental approach advocated is to right size, adjust remuneration structures, retrench and contract – out services.

The nature and potential effect of the Labour Relations Amendment Act 2002

Description: It took 18 months of intensive negotiation at the Millennium Labour Council, NEDLAC and the Labour Portfolio Committee before the Labour Relations Amendment Act of 20021 completed its passage through Parliament, taking effect on 1 August 2002. Fifty-seven amendments to specific sections of the Labour Relations Act2 and its schedules cure some obvious anomalies in the original version. It is further apparent that the legislature has taken cognisance of the observations by judges and arbitrators, who voiced their criticism in respect of certain aspects of the original "Act". The amended "Act"3 does appear to be a genuine commitment by both business and organised labour to improve efficiency in the labour market, to promote employment creation and to protect vulnerable workers. Improved dispute resolution mechanisms, enforcement mechanisms and the resurgence of an unfettered discretion in awarding compensation go some way to improving the application of the "Act". The most dramatic amendments have taken place in the law regulating retrenchments by large employers, inclusive of the controversial introduction of a right to strike after retrenchments of this nature have been effected, and the regulation of the transfer of a business as a going concern and its impact on workers. Critics indicate that business and organised labour have subscribed to the package of amendments despite respective reservations and due to certain time constraints. The nett result is a package of amendments that could be described as failing to address, in certain respects, or intentionally overlooking, areas of the "Act" that have traditionally been shown wanting in the past. In the individual employment law sphere specifically, the failure to address the meaning of "benefits" in the definition of unfair labour practices; to allocate a precise meaning to the concept of the transfer of a going concern; or to regulate the conduct of employers when transferring employees, remain some of the areas for concern. It appears that the legislature has decided that certain issues should be resolved by the Labour Court, and ultimately the Labour Appeal Court, on a case-by-case basis rather than by legislative intervention. Whilst this approach has merit, it does present problems to those seeking to apply the provisions of the amended "Act" 5 in everyday practice. On the whole, the amendments do not, nor were they designed to, mark a major shift in the government's labour market policy. The changes clearly focus on correcting and clarifying sections of the "Act", which have resulted in unintended consequences, or lost touch with commercial reality, over the past seven years.

Description: This research considers the relationship between tourism and development, and how tourism can be used as a means of promoting development. In order to explore this relationship, two districts in the Eastern Cape province of South Africa, the Albany and Peddie Districts have been selected as case study areas. Both the Albany and Peddie Districts are in need of development which can meet the economic and social development of the districts. One such option for the two districts is tourism-based development. This research examines the current status of tourism in both districts through the use of secondary data analysis and primary data gathered from questionnaires and interviews undertaken with tourists and representatives of key stakeholders in the tourism industry. This data was used to establish the current and future potential of tourism in the districts in terms of the availability and diversity of attractions and the tourism assets and facilities in the districts. It was also used to determine whether or not tourism, by promoting infrastructural and economic development, may lead to the socio-economic upliftment of the Albany and Peddie Districts. The results obtained from this research highlight the significant lack of tourism infrastructure in the Peddie District, and the reality that the tourism potential of the district remains untapped. With the marketing and promotion of tourism to the district, and the associated tourist requirements such as accommodation, and other facilities, tourism does hold a potential key to the socio-economic development of the district. The Albany District, however, has a well-established tourism industry, but the development spin-ofts are minimal, and the potential for further tourism-based development in the future would therefore appear to be somewhat limited. A GIS (Geographic Information System) was use to determine and detail possible tourism routes, a final outcome of the investigation being the proposal of two tourism routes to draw people into and through the study area, based on the current assets and attractions of the two districts. These routes highlight one of the options available in the districts to promote much needed development in the two districts through the use of the tourism industry. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

This complex showed five quasi-reversible/reversible, diffusion-controlled redox couples. Solution voltammetry of 1a showed little contrast with that of its alkythiol-derivative, octabutylthiophthalocyaninatozinc(II) [ZnPc(SC4H9)8] (1b) in that both thiol-substituents tend to show electron-withdrawing influence on the phthalocyanine ligands; complex 1a showing easier reduction and more difficult to oxidation when compared to 1b and other alkyl derivatives. The voltammetric features of the solid ultrathin films of 1a and 1b, immobilized on gold electrodes via the self-assembling technique, are also presented. Interestingly, the self-assembled films are stable and reproducible and provide good suppression to the following Faradaic processes; gold surface oxidation, solution ion species and underpotential deposition (UPD) of copper.

Description: Relationship marketing has grown in importance. This growth affects all industries, including the tourism, hospitality and travel industry. Of particular importance is the bond of relationship marketing between suppliers (principals) and retailers (travel agents) in the distribution channel. The research was undertaken to: determine whether Eastern Cape travel agents perceive relationship marketing as important; establish, what the key elements of relationship marketing strategies are,according to literature; determine what marketing strategies are currently applied by Eastern Cape travel agents; provide guidelines to Eastern Cape travel agents to implement or improve their relationship marketing strategies. Fifty self-administered questionnaires were distributed to the entire population of travel agents in the Eastern Cape. A total of 30 travel agents responded. The empirical findings showed that: Most Eastern Cape travel agents perceived relationship marketing as important; Travel agents realized the importance of the management of such relationship marketing strategies; Most travel agents were aware of or used retention strategies to enhance relationship marketing strategies; Travel agents realized that to survive relationship marketing should be part of their future planning; All respondents believed that to successfully implement relationship marketing, all staff, from front-line to top-management, need to be committed to the programme. In conclusion, relationship marketing is growing in importance and all role players need to acknowledge and manage this trend. However, this research has shown that there is a paradigm shift as more travel agents are moving away from the traditional marketing to relationship marketing.

Description: The thesis is that contrary to the received popular wisdom, the combination of David Hume's sceptical enquiry and Charles Darwin's provision of an alternative theoretical framework to the then current paradigm of natural theology did not succeed in defeating the design argument. I argue that William Paley's work best represented the status quo in the philosophy of biology circa 1800 and that with the logical mechanisms provided us by William Dembski in his seminal work on probability, there is a strong argument for thr work of Michael Behe to stand in a similar position today to that of Paley two centuries ago. The argument runs as follows: In Sections 1 and 2 of Chapter 1 I introduce the issues. In Section 3 I argue that William Paley's exposition of the design argument was archetypical of the natural theology school and that given Hume's already published criticism of the argument, Paley for one did not feel the design argument to be done for. I further argue in Section 4 that Hume in fact did no such thing and that neither did he see himself as having done so, but that the design argument was weak rather than fallacious. In Section 5 I outline the demise of natural theology as the dominant school of thought in the philosophy of biology, ascribing this to the rise of Darwinism and subsequently neo-Darwinism. I argue that design arguments were again not defeated but went into abeyance with the rise of a new paradigm associated with Darwinism, namely methodological naturalism. In Chapter 2 I advance the project by a discussion of William Dembski's formulation of design inferences, demonstrating their value in both everyday and technical usage. This is stated in Section 1. In Sections 2 and 3 I discuss Dembski's treatment of probability, whilst in Section 4 I examine Dembski's tying of different levels of probability to different mechanisms of explanation used in explicating the world. Section 5 is my analysis of the logic of the formal statement of the design argument according to Dembski. In Section 6 I encapsulate objections to Dembski. I conclude the chapter (with Section 7) by claiming that Dembski forwards a coherent model of design inferences that can be used in demonstrating that there is little difference between the way that Paley came to his conclusions two centuries ago and how modem philosophers of biology (such as I take Michael Behe to be, albeit that by profession he is a scientist) come to theirs when offering design explanations. Inference to the best explanation is demonstrated as lying at the crux of design arguments. In Chapter 3 I draw together the work of Michael Behe and Paley, showing through the mechanism of Dembski's work that they are closely related in many respects and that neither position is to be lightly dismissed. Section 1 introduces this. In Section 2 I introduce Behe's concept of irreducible complexity in the light of (functional) explanation. Section 3 is a detailed analysis of irreducible complexity. Section 4 raises and covers objections to Behe with the general theme being that (neo-) Darwinians beg the question against him. In Section 4 I apply the Dembskian mechanic directly to Behe's work. I argue that Behe does not quite meet the Dembskian criteria he needs to in order for his argument to stand as anything other than defeasible. However, in Section 5 I conclude by arguing that this is exactly what we are to expect from Behe's and similar theories, even within competing paradigms, in the philosophy of biology, given that inference to the best explanation is the logical lever therein at work. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

Description: The research described in this thesis is a case study of the communicative repertoires of teachers and learners of a grade seven class in a small rural primary school. The aim of the investigation was to find out if code switching is different in content-subject classes than in an English language class. The study accomplishes this by looking at code switching in different learning areas. Different research techniques such as observations, video. recording, taking of field notes and interviews are used as the means of data collection. The study does not attempt a full linguistic description of the switches made by the research subjects.
