- Description: The development of the National Forestry Action Programme (NFAP) and promulgation of the National Forests Act (NFA) have established a new vision for the care, management and distribution of benefits from South Africa's woodlands. The Department of water Affairs and Forestry is mandated with ensuring this vision is put into practice. However, historically the Department has had little to do with woodlands, and suffers from a lack of capacity and expertise, a situation which it readily acknowledges. Additionally, the legal definition of a woodland within the NFA is problematic. Within this context, this paper examines oft cited definitions of woodlands and seeks to find an appropriate one for the South African context. It then briefly reviews the major classifications of woodland types at a national scale, as the minimum basis for homogenous reporting units for which monitoring of the success of the NFAP and the NFA should be pursued. Finally, a brief description of moist/dystrophic and arid/eutrophic woodlands is presented.

- Description: This Review and project will discuss and demonstrate the use made of Biotechnology in the production and reduction of metals. It will look at how and why metal binding takes place, known platinum group metal speciation will be included. Examples of how to improve metal binding efficiency will be discussed by stimulating ligand activity by polarisation. Various biotechnical options available, with emphasis placed on the use of the aquatic fern and algae will be given as examples of biological treatment of heavy metals in particular the aquatic fern Azolla. The method of standard preparation and the use of Inductively Coupled Plasma Emission Spectrophotometer (ICP) used for analytical analysis will be included so that consideration can be given to the collection of analytical data in the provision of evidence to support or provide a conclusion. The outcome of the test work utilising the aquatic plant Azolla has proven that it can be used to remediate platinum refinery effluent. This process can offer an alternative to the classical chemical method normally used, which is economically viable and environmentally friendly in comparison to the common methods of refinery effluent treatment. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Biotechnology, 200u

- Description: The South African Schools’ Act of 1996 terminated segregated education in South Africa. Multi-cultural education has become a reality in the new democratic South Africa. As a result of this major shift in policy, the researcher probed for an answer to the following question: “How does the teacher, especially the teacher already in service, experience this new situation regarding multi-cultural education?” To find an answer to this question, a literature study and empirical research, making use of a representative sample of respondents in the Southern Cape, were undertaken. The researcher has personally experienced the challenges of having to adapt from a mono-cultural teaching environment to a multi-cultural teaching environment at school level, hence a further interest in this research problem. Relevant terminology was highlighted and a brief historical synopsis of the course that multi-cultural education took in Western societies such as the USA, Canada, Australia and Britain was studied. These sources were utilised to draw a comparison with the South African situation. A concise synopsis of the history of multi-cultural education in South Africa was also undertaken to highlight the complexity of the educational situation presently being experienced in South Africa. The empirical research, with a target group representing teachers in the Southern Cape, was undertaken by means of a self-compiled questionnaire to make an analysis of teachers’ attitudes, expectations and perceptions of multi-cultural education as experienced in the classroom. The information obtained from the respondents indicated a generally positive attitude towards multi-cultural education amongst teachers. A great need for in-service training also became evident. xvi The researcher has thus made recommendations regarding in-service training that she thinks is of utmost importance. The practical problems that were highlighted during the research, make a vital contribution towards the successful implementation of multi-cultural education in South Africa. , Thesis (DEd) -- Faculty of Education, 1999

- Description: Adsorptive cathodic stripping voltammetric (AdCSV) studies of gold(III) on a glassy carbon electrode and in the presence of yeast mannan are reported. These studies give evidence of the formation of a complex between gold(III) and mannan in acid media as judged by the enhancement in the AdCSV currents and shift in the reduction peak of gold(III) in the presence of mannan. The AdCSV currents were linearly dependent on gold(III) concentrations ranging from 7.0 × 10−7 to 3.0 × 10−4 mol dm−3. A detection limit of 6.0 × 10−8 mol dm−3 was obtained. Interferences of copper(II) were observed in the presence of mannan, but there was no significant interference of silver(I).

- Description: Studies on the catalytic reduction of nitrite on carbon electrodes modified with Co(II) tetra-2,3-pyridinoporphyrazine (CoTppa, 1), N,N′,N′′,N′′′-tetramethyltetra-2,3-pyridinoporphyrazine ([CoTm-2,3-tppa]4+, 2) and Co(II) N,N′,N′′,N′′′-tetramethyltetra-3,4-pyridinoporphyrazine ([CoTm-3,4-tppa]4+, 3) are reported. There is a close correspondence between the proximity of the methyl groups to the porphyrazine ring and the catalytic activity of the porphyrazine complexes. Bulk electrolysis gave ammonia and hydroxylamine as some of the products. The catalytic activity of the cationic complex, 3, towards the detection of low concentrations of nitrite (less than 10−9 M) in water containing sodium sulfate, was compared with the activities of the anionic cobalt(II) tetrasulfophthalocyanine ([CoTSPc]4−, 4) and the mixed [CoIITm-3,4-tppa]4+·[CoTSPc]4− (5) complexes. Complex 5 showed the best catalytic activity of the three in that large currents were obtained for very low concentrations of nitrite.

- Description: In recent decades, Pacific Region indigenous sea tenure regimes have received considerable attention from social scientists who believe thatmarine-localized common entitlements and fishing practices can aid modern littoral fisheries management. The endorsement of sea tenure institutions as managerial tools, however, has proceeded without adequate consideration of their vulnerability to social and economic changes. The general view held by researchers is that Pacific Island Sea tenure regimes are generally undermined by the influence of exogenous forces resulting in an open-access commons. In this article, it is argued that the contemporary transformation of sea tenure regimes emerges not only from exogenous agency, but from a complex set of autochthonous processes. A case study from New Georgia, Solomon Islands, is presented to show how sea tenure regimes can vary within an ethnically and culturally homogeneous region. Three tenure models are presented to show how different pre- and post-European contact regional settlement patterns, localized processes of political expansion and contraction, and dynamic indigenous sociocultural principles have resulted in institutional differences between each sea tenure model. The effect of the market economy on the organizational structure and managerial outcomes of each model also is discussed.

For most of the excipients (magnesium stearate, stearic acid, Explotab®, Ac-Di-Sol®, Encompress® and Ludipress®, lactose and Starch 1500) disappearance or broadening of the melting endotherm of the drug indicated interactions. Lubritab® was the only 'inert' excipient tested. Mixtures of prochlorperazine and the cyclodextrins gave incomplete inclusion complexation as shown by only partial disappearance of the melting endotherm of the drug.

- Description: Spectroscopic changes observed on addition of nitrite to solutions of cobalt(II) tetra-sulfophthalocyanine ([Co(II)TSPc]4-) in the presence of N− 3 or ClO− 4 are reported. There is spectroscopic evidence for the oxidation of [Co(II)TSPc]4- to a [Co(III)TSPc]3- species in the presence of nitrite ions. Equilibrium and kinetic studies for the interaction between [Co(II)TSPc]4- and NO− 2 are reported. The rate was found to be first order in both [Co(II)TSPc]4- and NO− 2. The rate constant for the forward reaction, k f=1.6 × 10−4 dm3mol−1s−1 was determined at 20°C for the interaction between nitrite ions and [Co(II)TSPc]4- in the presence of NO3 − or ClO4 − ions.

- Description: The aim of this thesis is to promote the dramatological approach, as opposed to a literary critical one, for the analysis of dramatic texts for the purposes of staging. The reason for such a promotion is that the dramatological approach upholds the integrity of the text in interpretation for the performance text by its detailed and semiotic analysis. The focus of such an approach is on the analysis of discourse, that is a micro-proairetic approach (illuminating the extralinguistic action and interaction gained from speech events and deixis), rather than a macro-proairetic approach (that is, plot and story-line) which a literary critical approach would take into consideration. In Chapter one the focus is on the justification for the dramatological approach as well as a review of prominent literary criticism to the playwright’s work (used as an example of dramatic text in this thesis). Rather than the promotion of ordinary literary theory in relation to the need for a performance methodology, explanation for their negation is offered here. Chapter two focuses on the actual methodology of the dramatological approach. In section one of this chapter, we find that basic to dramatological methodology is the linguistic function appropriate to the dramatic: that is the semantic, rhetorical and pragmatic principles of dramatic dialogue. In addition, we find that it is a formal and systematic approach which imposes restrictions on dualisms thereby upholding the integrity of the text. Moreover, that it focuses on the “performative-deictic” character (that is extralinguistic, kinesic and indexical orientations) of the dramatic text - analysis of which is crucial for the purposes of staging. In this way, the analysis of the interpersonal, interactional and contextual areas of dramatic texts is promoted. Thus section one offers an overview of the analytical criteria appropriate to such investigation in order to illuminate dramatic discourse. Section two offers a guide to the application of the methodology, utilizing an extraction of text. Central to the application is the formation of a preliminary analytical ‘grid’ from the range of criteria discussed in section one; that is, how these may be put together. A micro-segmentation of text is utilized to illustrate the application of the methodology. Chapter three offers an application of the methodology to a whole text, that is The Dumb Waiter. The results and benefits for the theatre practitioner of such application are directly illustrated in the deictic (that is section one) and proairetic (that is section two) segmentations of the text since what the text and discourse signify is illustrated in a detailed manner as opposed to paraphrase. That is, the interpersonal, contextual and interactional levels of the drama are defined. From this, typologies of discourse, character and interrelationships are drawn, as well as a creation of the dramatic world (that is section three) constructed as a result of the discourse, interrelationships and dramatic action. Finally the Conclusion offers an evaluation of the dramatological approach by applying it to a practical situation for the theatre practitioner (that is, director or actor). , Thesis (MA) -- Faculty of Humanities, Drama, 1999

- Description: The aim of this thesis is to promote the dramatological approach, as opposed to a literary critical one, for the analysis of dramatic texts for the purposes of staging. The reason for such a promotion is that the dramatological approach upholds the integrity of the text in interpretation for the performance text by its detailed and semiotic analysis. The focus of such an approach is on the analysis of discourse, that is a micro-proairetic approach (illuminating the extralinguistic action and interaction gained from speech events and deixis), rather than a macro-proairetic approach (that is, plot and story-line) which a literary critical approach would take into consideration. In Chapter one the focus is on the justification for the dramatological approach as well as a review of prominent literary criticism to the playwright’s work (used as an example of dramatic text in this thesis). Rather than the promotion of ordinary literary theory in relation to the need for a performance methodology, explanation for their negation is offered here. Chapter two focuses on the actual methodology of the dramatological approach. In section one of this chapter, we find that basic to dramatological methodology is the linguistic function appropriate to the dramatic: that is the semantic, rhetorical and pragmatic principles of dramatic dialogue. In addition, we find that it is a formal and systematic approach which imposes restrictions on dualisms thereby upholding the integrity of the text. Moreover, that it focuses on the “performative-deictic” character (that is extralinguistic, kinesic and indexical orientations) of the dramatic text - analysis of which is crucial for the purposes of staging. In this way, the analysis of the interpersonal, interactional and contextual areas of dramatic texts is promoted. Thus section one offers an overview of the analytical criteria appropriate to such investigation in order to illuminate dramatic discourse. Section two offers a guide to the application of the methodology, utilizing an extraction of text. Central to the application is the formation of a preliminary analytical ‘grid’ from the range of criteria discussed in section one; that is, how these may be put together. A micro-segmentation of text is utilized to illustrate the application of the methodology. Chapter three offers an application of the methodology to a whole text, that is The Dumb Waiter. The results and benefits for the theatre practitioner of such application are directly illustrated in the deictic (that is section one) and proairetic (that is section two) segmentations of the text since what the text and discourse signify is illustrated in a detailed manner as opposed to paraphrase. That is, the interpersonal, contextual and interactional levels of the drama are defined. From this, typologies of discourse, character and interrelationships are drawn, as well as a creation of the dramatic world (that is section three) constructed as a result of the discourse, interrelationships and dramatic action. Finally the Conclusion offers an evaluation of the dramatological approach by applying it to a practical situation for the theatre practitioner (that is, director or actor). , Thesis (MA) -- Faculty of Humanities, Drama, 1999

- Description: After years of isolation from the international sporting arena, South African sports teams have recently achieved much success. This article is concerned specifically with managing for organisational effectiveness in South African cricket According to the theory of transformational leadership, there should be a positive relationship between this style of leadership and organisational effectiveness. The Multifactor Leadership Questionnaire was used to collect information about leadership while data for organisational effectiveness, the dependent variable, was collected using the Effectiveness Survey for Cricket Administration. Most of the results regarding the relationship of the transformational leadership factors and organisational effectiveness were significant. On the other hand, most of the results regarding the relationship of the transactional leadership factors and organisational effectiveness were not significant. The overall results provide general support of Bass' (1990) argument of the universal application of the transformational leadership theory.

- Description: A viable synthetic route to camphor-derived imino lactones as precursors for the asymmetric synthesis of a-amino acids has been established. Several synthetic strategies have been investigated and the required regioisomeric imino lactones were finally obtained via the step-wise condensation of JV-(carbobenzyloxy)glycine with the a-ketols, 3-exo-hydroxycamphor and 2-exo- hydroxy-3-bomanone. Enolates of the camphor imino lactones, generated using potassium tert- butoxide, were reacted with a range of alkyl halides. Dialkylation was observed using the 2-imino lactone, while the regioisomeric 3-imino lactone derivative gave monoalkylated products with diastereoselectivities, shown by NMR spectroscopy, to range from 43% d.e. for the methylated product to > 99% d.e. for larger alkyl groups. The expected preference for endo-alkylation is supported by NMR (chemical shift, coupling constant and NOE) data and was confirmed by acidic hydrolysis of the pentylated 3-imino lactone to afford the known acid. Computer modelling, with the software package HYPERCHEM®, was used to explore the conformational properties of the alkylated products and their enolate precursors. Exploratory work on the enantiomeric beneficiation of racemic amino acids, using alkylated imino lactone derivatives, revealed preferential exo-protonation of the enolate intermediates. Asymmetric Baylis-Hillman reactions between a novel camphor-derived acrylic ester and a range of aldehydes afforded the corresponding 2-(hydroxyalkyl)acrylates in up to 59% d.e., the observed stereoselectivities being sensitive to both steric and electronic factors. Attempts to prepare imino lactone derivatives from ketopinic acid, although unsuccessful, led to the isolation of two novel W-(carbobenzyloxy)glycinates, whose structures were established by 1- and 2-D NMR spectroscopy. Attempts to prepare "BINAP" analogues from dibomyl ether's also proved unsuccessful, but the investigation led to the discovery of a third, novel dibomyl ether. , Thesis (PhD) -- Faculty of Science, Chemistry, 1998

- Description: Learning for Sustainability is a Danish-funded project for supporting teachers in environmental education curriculum development, in the Departments of Education in the Gauteng and Mpumalanga provinces of South Africa. The Rhodes University Environmental Education Unit is responsible for its evaluation. Instead of establishing baseline data against which to compare the project outcomes, the researchers are developing contextual profiles towards a deepening understanding of the contexts in which the teachers work, and to judge the appropriateness of project activities. This paper introduces insights from the developing profile based on questionnaires; interviews; observations during project meetings and school visits; and document analysis. The emerging issues pertain to curriculum and professional development in environmental education, within the context of educational policy transformation. In particular the paper highlights the role of context in responsive reform initiatives.

- Description: The 1998 EEASA Conference-and-Workshops meeting was a sound success. The Botswana organisers must be congratulated on convening such a convivial and stimulating event. The conference gave exposure to some of the environmental education research in progress in the region. While there is an exciting level of regional research activity, this is not adequately represented in the Southern African Journal of Environmental Education, or any other published forum for that matter. The SAJEE receives a rather small number of research papers from southern Africans for review; in addition the journal's referees and editors judge an even smaller number of these as suitable for publication. What this reflects, inter alia, is the need for environmental educators in the region to write more vigorously about their research.

- Description: The in vitro release characteristics of amoxycillin from different lipophilic suppository bases were investigated using the USP rotating basket method. Suppositories containing 250 mg amoxycillin were prepared in theobroma oil and in the semisynthetic bases Witepsol W35, Suppocire A32, Novata BD, and Novata 299. Both freshly prepared and 1-month-old suppositories were tested. Analysis of amoxycillin was performed using a validated high-performance liquid chromatographic (HPLC) technique. Release profiles differed significantly between bases, with the greatest amount of amoxycillin being released from both newly made and 1-month-old Novata BD bases (87.57 ± 8.18 and 99.66 ± 6.63%, respectively), and the lowest amount released from the newly manufactured theobroma suppositories (8.82 ± 0.75%) and the 1-month-old Suppocire A32 suppositories (7.78 ± 0.27%).

- Description: The coordination of nitric oxide (NO) to cobalt(II) phthalocyanine (CoPc) in dimethyl sulphoxide (DMSO) has been studied. CoPc coordinates with NO in a 1:1 ratio, forming a CoPc(NO) species. The IR band observed at 1680 cm−1 is assigned to the coordinated NO. In the presence of excess NO, pseudo first order kinetics were followed. The observed rate constant, kf, was determined to be 15.0±0.3 dm−3 mol−1 s−1 and the equilibrium constant was K=5.4±0.4×104dm3 mol−1. Solution or adsorbed CoPc catalyses the reduction of NO. The products of reduction include NH3 and NH2OH.

- Description: Numerous researchers in the field of maritime anthropology have accepted the notion that marine tenure institutions are cultural systems designed to conserve marine resources. This idea has attained wide acceptance without the development of an ecological model to account for the occurrence of conservation and/or depletion of resources. In this study, foraging theory is offered as an alternative theoretical framework to examine the diversity of human resource exploitation strategies in coastal ecosystems. The results generated by the foraging models are considered here in relation to their significance in linking ecological evolutionary approaches in anthropology with coastal resource management.

- Description: Diphthalocyanine complexes of Nd III, EuIII, TmIII and LuIII ( [Pc (−2) Nd IIIPc (−2) ] −, [Pc (−2) EuIIIPc (−2) ] −, [Pc (−2) TmIIIPc (−2) ] − and [Pc (−2) LuIIIPc (−2) ] −, respectively) , undergo one or two-electron oxidation in the presence of thionyl chloride. The oxidation products depend on the concentration of the thionyl chloride. At low concentrations of SOCl2 (larger than 10−4 mol dm−3) one-electron oxidation occurs only upon photolysis, giving the neutral lanthanide diphthalocyanine, Pc (−2) LnPc (−1) , complexes. The Pc (−2) LnPc (−1) species undergo one-electron photooxidation to the [Pc (−1) LnPc (−1) ] + in dichloromethane and in the presence of SOCl2. At large concentrations of SOCl2 (>10−2 mol dm−3) , two electron oxidation of the [Pc (−2) LnPc (−2) ] − species directly to [Pc (−1) LnPc (−1) ] + occurs.
