- Description: News in our contemporary newspapers has come to be associated more and more with what the elites do and say. Both their deeds and misdeeds are treated as newsworthy events and in the process they become newsmakers, both actors and sources of news. Even when they are not directly involved in news events they are sought out by journalists to validate those events and to interpret the social reality to the readers as news sources. This study is about the selection of news sources in the Daily Nation, a contemporary, independent newspaper based in Nairobi, Kenya. In this study, I set out to unravel the complex processes that underlie newsmaking and source selection. This study is informed by the theory of news values and the paradigm of the role of media in democracy. Based on qualitative interviews, observations and content analysis of the front-page stories, it investigates the process of news and source selection in front-page stories. Through these approaches, I established that news values are significant criteria that inform journalists in both the selection of front-page news stories and the sources of these stories. I also established that social values of the society in which this newspaper operates are heavily embedded in the news. For example, the journalists preferred male politicians as sources of news in the front-page stories to women, and the elites to ordinary people, and this reflected on the social structures and cultural norms that are prevalent in this society. This study, further, established that the news values of this newspaper share commonly with the Western news media in terms of journalistic conventions and ways of interpreting the social reality in the news. Ideally, the newspaper embraces the principles of democracy in news reporting, but in practice it does not satisfactorily adhere to the full requirements of its democratic role in terms of source selection. The democratic principles in news reporting require, among other things, that the newspaper should allow a diversity of views in the news, representing various groups that are found in real society including the elites, non-elites, women, ordinary people and minorities. In the case of the Daily Nation, a tiny group of elite male professional politicians made up the largest majority of its front-page news sources.

- Description: Cyclizine is a piperazine derivative with anti-emetic activity that is useful in the prevention and treatment of nausea and vomiting associated with motion sickness. A liquid chromatography-tandem mass spectrometry (LC-MS-MS) method is presented for the quantitation of cyclizine in serum. Sample pretreatment involved liquid-liquid extraction of 200 μl of serum with dichloromethane after the addition of 100 μl each of ammonium hydroxide and internal standard solutions. The extracts were analyzed by HPLC on a Luna ® C18 reversed-phase column and an ion-trap mass spectrometer with an electrospray interface. A limit of detection of 1 ng/ml was determined which allowed for the reliable measurement of cyclizine in the serum of human subjects. The method was found to be linear over the calibration range of 2.5-100 ng/ml. The applicability of this method was demonstrated by the analysis of serum obtained from a human volunteer following administration of a single 50 mg cyclizine hydrochloride tablet. The reported method was observed to have the necessary sensitivity, selectivity, precision and accuracy for monitoring cyclizine concentrations in human subjects following oral administration.

- Description: “We often spend too much time coping with problems along our path that we forget why we are on that path” Peter Senge This study describes and analyses the implementation of Organisation Development (OD) to a previously disadvantaged school. OD is a relatively new method of planned change in South Africa. Unlike more traditional change initiatives, OD promotes collaboration; it tries to involve all members of an organisation in problem solving and decision-making. It is an applied behavioural science discipline dedicated to improving organisations and the people in them. Previously disadvantaged schools in South Africa continue to be disadvantaged. Ten years after the introduction of democracy there have been few changes in some of these schools and some seem to be getting worse. This study was an attempt to introduce a process of planned change to one such school. Since 1994 many changes have been imposed on our schools with new curricula, increased class sizes, changes in systems of assessment and teaching methods and the abolishment of past procedures such as corporal punishment. Teachers have had little say in any of these changes and this has resulted in resistance, resignation, frustration and in many cases a lack of ability to cope. OD was introduced to Acacia High School in the form of a Survey Data Feedback (SDF). An action research process followed and a diagnosis was made followed by action planning and then the execution of a plan. My study follows this process and the implementation of the plan describing its successes. Sadly change was not sustained and I highlight some of the challenges that face the school in order to bring about real long-term improvement in the culture of learning and teaching.

- Description: In the New South Africa, as in other developing countries, the equitable distribution of public resources is a priority. The case for public support of the arts is thus difficult to make because it has been shown and borne out by South African research, that arts audiences tend to represent the better educated, more prosperous minority of society, not the majority of the very poor, mainly African-origin population. Using data from willingness to pay studies conducted at two South African arts festivals, this paper shows that, when the positive externalities provided by the arts are included in their valuation, it can be shown that both high and low income earners benefit. However, as suggested by Seaman (2003), it is also found that some of what the WTP figure is capturing is current and expected future economic benefit from the event.

- Description: The rule excluding evidence of opinion is traditionally stated in broad and general terms, subject to a more or less closed list of exemptions. Stephen says that a witness’s opinion is “deemed to be irrelevant”. A witness may depose to the facts which he has observed, but he may not ordinarily state any inferences which he has drawn from those facts, or opinions founded upon facts of which he has no personal knowledge. The general rule is that the evidence of opinion or belief of a witness is irrelevant because it is the function of a court to draw inferences and form its opinion from the facts; the witnesses give evidence as to the facts and the court forms its opinion from those facts. The opinion of an expert is admissible if it is relevant. It will be relevant if the witness’s skill, training or experience enables him materially to assist the court on matters in which the court itself does not usually have the necessary knowledge to decide. Where the topic is such that an ordinary judicial officer could be expected to be able, unassisted, to draw an inference, expert evidence is superfluous. In principle, there is no rule that a witness cannot give his opinion on an issue that the court has to decide ultimately. It is not experts alone who may give their opinions on ultimate issues but, in practice, there is a strong tendency to regard the evidence of lay persons on ultimate issues as constituting prima facie evidence only. If such lay testimony remains unchallenged, it may be of greater significance. It is generally true that relevant evidence is admissible and irrelevant evidence is inadmissible. At this stage the following question may be posed: is the opinion of any witness – whether from an expert or lay person – admissible evidence? Should an opinion be admitted for purposes of persuading the court to rely on it in deciding the issue at hand? The basic answer is that relevance remains the fundamental test for admissibility. Certain issues simply cannot be decided without expert guidance. Expert opinion evidence is therefore readily received on issues relating to ballistics, engineering, chemistry, medicine, accounting and psychiatry, to mention only a few examples. The problem which arises is this: what is the best way of cross-examining the expert witness? Although the concept of skilful cross-examination conjures up the image of the crossexaminer destroying the expert witness in the witness box, total annihilation of expert evidence in court occurs only rarely. In reality, lawyers who are expected to cross-examine experts are often at a disadvantage in that they do not possess sufficient in-depth knowledge of the specific field of expertise to enable them to cross-examine the witness. Despite the expert nature of the evidence, it is suggested that the true basis of crossexamination should not be abandoned when dealing with experts. The effectiveness of crossexamination is enhanced by keeping the number of questions to a minimum as well as opening and concluding with good strong points. At the outset it should be mentioned that there is a distinction between matters of scientific fact and matters of mere opinion. On matters of scientific fact experts seldom differ but within the province of opinion one encounters difficulties. Lengthy cross-examination concerning expert’s theoretical knowledge is usually inefficient and should rarely be attempted. Cross-examination should be directed at pure logic or scientific analysis. The cross-examiner should always have relevant authority with him in court so as to confront the expert with these. The whole effect of the testimony of an expert witness can also be destroyed by putting the witness to test at the trial as to his qualifications, his experience and his ability and discriminations as an expert. A failure to meet this test renders his evidence nugatory.

- Description: Global trends in teleost fisheries indicate significant population declines. Thus, alternative fisheries are being developed to meet the growing economic and nutritional demands of the expanding human population. Recently, it has been established that elasmobranch fisheries may fulfill these demands. As many elasmobranchs possess life-history characteristics that make them particularly vulnerable to overfishing, it is imperative to develop management strategies prior to the inception of these fisheries to ensure sustainable resource utilisation. In South Africa, elasmobranchs have been commercially exploited since the 1930s. Although generally considered an under-exploited resource, the potential for growth within these fisheries has been recognized. In 2005, the commercial shark fishery will undergo a transition from medium to long-term rights allocations. This represents an ideal opportunity for scientists and managers to develop precautionary species-specific management plans for commercially exploitable elasmobranch species. The soupfin shark (Galeorhinus galeus) is one of the principal target species in South Africa’s shark fisheries. Given its inherent susceptibility to overexploitation, G. galeus was selected as a management priority by South Africa’s regional fisheries organisation. The purpose of this study was to examine and describe the stock status of G. galeus in South Africa, and to develop a precautionary fishery management plan to ensure the sustainability of this resource. Age, growth, and mortality calculations for G. galeus were made from research survey data collected between 1996 and 1999. A small sample size precluded independent analyses of females. The maximum recorded age for G. galeus was 33 years. Estimated von Bertalanffy growth parameters from observed length-at-age for males and combined sexes were: L∞ 1542.8 mm TL, K 0.21 year⁻¹ , t₀ -2.79 year⁻¹ and L∞ 1560.3 mm TL, K 0.19 year¹, t₀ -3.03 year⁻¹, respectively. The age-at-50% maturity was determined to be 6 years, corresponding to 1011 mm TL for males and 1100 mm TL for combined sexes. Natural mortality was calculated as 0.126 yr⁻¹. The rate of instantaneous total mortality was calculated as 0.27 yr⁻¹. Catch trend analysis showed that catches and CPUE of G. galeus are increasing in the demersal longline fishery, and decreasing in the handline fishery. Decreasing catches and CPUE were observed in fishery-independent research survey data. The status of the soupfin shark stock was modelled using per-recruit analysis. The SB/R model indicated the soupfin shark is being optimally exploited and spawner biomass is at 43% of preexploitation levels. Current fishing levels ( F = 0.14 yr⁻¹) approximate the Fsb₄₀ level (F = 0.17 yr¹); thus, an increase in fishing pressure may lead to stock collapse. It was determined that the current age-at-capture (7.9 years) should be increased to 10 years, or 1420 mm TL, to maximize yield and minimize the possibility of recruitment failure. The results of this study indicate a need for immediate scientific and management intervention in South Africa’s soupfin shark fishery. An assessment report and fishery management plan for G. galeus was compiled, and several management options were proposed. These include the implementation of licence and size restrictions, as well as seasonal/area closures. The potential for an experimental gillnet fishery should be investigated.

- Description: Global trends in teleost fisheries indicate significant population declines. Thus, alternative fisheries are being developed to meet the growing economic and nutritional demands of the expanding human population. Recently, it has been established that elasmobranch fisheries may fulfill these demands. As many elasmobranchs possess life-history characteristics that make them particularly vulnerable to overfishing, it is imperative to develop management strategies prior to the inception of these fisheries to ensure sustainable resource utilisation. In South Africa, elasmobranchs have been commercially exploited since the 1930s. Although generally considered an under-exploited resource, the potential for growth within these fisheries has been recognized. In 2005, the commercial shark fishery will undergo a transition from medium to long-term rights allocations. This represents an ideal opportunity for scientists and managers to develop precautionary species-specific management plans for commercially exploitable elasmobranch species. The soupfin shark (Galeorhinus galeus) is one of the principal target species in South Africa’s shark fisheries. Given its inherent susceptibility to overexploitation, G. galeus was selected as a management priority by South Africa’s regional fisheries organisation. The purpose of this study was to examine and describe the stock status of G. galeus in South Africa, and to develop a precautionary fishery management plan to ensure the sustainability of this resource. Age, growth, and mortality calculations for G. galeus were made from research survey data collected between 1996 and 1999. A small sample size precluded independent analyses of females. The maximum recorded age for G. galeus was 33 years. Estimated von Bertalanffy growth parameters from observed length-at-age for males and combined sexes were: L∞ 1542.8 mm TL, K 0.21 year⁻¹ , t₀ -2.79 year⁻¹ and L∞ 1560.3 mm TL, K 0.19 year¹, t₀ -3.03 year⁻¹, respectively. The age-at-50% maturity was determined to be 6 years, corresponding to 1011 mm TL for males and 1100 mm TL for combined sexes. Natural mortality was calculated as 0.126 yr⁻¹. The rate of instantaneous total mortality was calculated as 0.27 yr⁻¹. Catch trend analysis showed that catches and CPUE of G. galeus are increasing in the demersal longline fishery, and decreasing in the handline fishery. Decreasing catches and CPUE were observed in fishery-independent research survey data. The status of the soupfin shark stock was modelled using per-recruit analysis. The SB/R model indicated the soupfin shark is being optimally exploited and spawner biomass is at 43% of preexploitation levels. Current fishing levels ( F = 0.14 yr⁻¹) approximate the Fsb₄₀ level (F = 0.17 yr¹); thus, an increase in fishing pressure may lead to stock collapse. It was determined that the current age-at-capture (7.9 years) should be increased to 10 years, or 1420 mm TL, to maximize yield and minimize the possibility of recruitment failure. The results of this study indicate a need for immediate scientific and management intervention in South Africa’s soupfin shark fishery. An assessment report and fishery management plan for G. galeus was compiled, and several management options were proposed. These include the implementation of licence and size restrictions, as well as seasonal/area closures. The potential for an experimental gillnet fishery should be investigated.

- Description: An analysis of the current monetary policy framework in South Africa, which followed the exampie of a number of developed countries by implementing an inflation-targeting regime in 2000, is presented. The primary goal of the framework is to establish price stability, with financial stability a secondary objective. However, as has been evident in other countries, price stability does not guarantee financial stability. Movements in asset prices and the development of asset price bubbles have resulted in a number of episodes of financial instability, which negatively impacted on the growth and development of the countries involved. In addition, the majority of these episodes have occurred in periods of low and stable inflation. The dissertation analyses whether monetary policy would be more efficient if asset price movements were incorporated within the inflation-targeting regime. International experience indicates that early intervention of monetary policy can dampen the negative effects that result when an asset price bubble "bursts". However, if the monetary authorities act too early the effects on the economy can be just as disruptive. The literature is scrutinized to establish what the most effective form of monetary policy should be. The results are then transposed within the South African context to establish how the South African Reserve Bank can best ensure both price and financial stability.

- Description: It is clear from these and other definitions that development, no matter how it is conceived, involves change. However, it is also clear that not all change constitutes development. A particular change could be part of a process of development, but could also be part of several other processes, such as those of alteration, modification, deformation, adaptation, regression, degradation and the like. Thus it is necessary to differentiate between changes that can be said to be part of a process of development, and those that cannot. In an attempt to make such a distinction and in line with the above-mentioned definitions of development one could say that changes that are part of development are changes that bring about increased likeness to some more advanced or better state of being. A six-year-old child who, after years of talking, becomes mute is regressing rather than developing; and a child whose behaviour changes such that she begins to act like a dog would be considered to be in some kind of disordered state. However, when a child’s behaviour undergoes changes that lead to increased similarity to some conception of adult behaviour, then that child can be said to be developing. When assessing whether changes in a child’s behaviour constitute development, or some other kind of process, one has to have in mind some conception of what the child ought to be becoming.

- Description: This article presents and discusses the results of a survey of a sample of Xhosa-speaking students at the University of Fort Hare regarding their attitudes towards the possible introduction of Xhosa as a medium of instruction at this institution. The research takes into account, among other things, the students' attitudes towards English and Xhosa and their opinions and beliefs about the introduction of dual-mediumship and its possible consequences. The survey was conducted with questionnaires and interviews and the results were first analysed as a whole, and then split into different categories according to gender, year of study, subject studied etc. This analysis indicates that while English is recognised as the dominant language in South Africa and, more specifically, in the domain of education, some categories of respondents acknowledge the usefulness of Xhosa as an additional medium of instruction. This survey clearly shows that it would make little sense to present Xhosa-speaking students at Fort Hare with a rigid choice between the existing English-medium and a dual-medium (English and Xhosa) policy and that more nuanced options would need to be offered. For example, respondents seem to consider the use of Xhosa as a medium of instruction more appropriate in the first years of study, for selected subjects and in some domains within the academic context rather than others. This study can be fruitfully compared with similar research carried out at other South African institutions. Moreover, the results of the present research can be used to inform future decisions regarding language policy at the University of Fort Hare.

- Description: The research problem in this study was to look at barriers confronting small and micro tourism enterprises of the previously disadvantaged entrepreneurs in the Nelson Mandela Metropole. To achieve this objective, literature on the barriers confronting these enterprises, was reviewed. The empirical results obtained indicate a strong concurrence with the literature study emphasizing the importance of the barriers identified and the possible ways of resolving them. The main problems identified in the literature review were: lack of institutional support, legislation, lack of access to finance, and lack of entrepreneurial skill (planning and organizing, marketing, training and human resources, time management, conflict resolution and negotiation skill). These barriers identified in the literature study were then used to develop a questionnaire to test the extent to which small and micro tourism enterprises are constrained by barriers when starting up and how these barriers can be resolved. A sample of 18 small and micro tourism businesses was taken, one from Uitenhage and 17 from Port Elizabeth. The main results were that there are few small and micro tourism businesses of the previously disadvantaged entrepreneurs in the Nelson Mandela Metropole. The main reason for this is that previously disadvantaged entrepreneurs are not given adequate support by government institutions created for that purpose. iv Most of these businesses are not getting enough financial support during start-up because of problems with the owners’ credit records. The results also indicate that small and micro tourism businesses of the previously disadvantaged entrepreneurs view legislation intended to develop them, as actually stifling their development, such as the municipal credit laws. The study recommends that more institutional support should be given to small and micro tourism businesses that are starting up, and government institutions responsible for the development of small and micro businesses need to target the previously disadvantaged communities with their marketing. The Nelson Mandela Metropolitan Municipality and the Small Enterprise Development Agency (SEDA) need to conduct research on alternative non-collateral financing for small and micro businesses. More training programmes on business skills have also to be conducted.

- Description: The Population Registration Act of 1950, in the apartheid period of South African history, defined a coloured person as “a person who is not a White person or a Black”. In differentiating coloured from white, coloured from black, and black from white, somatic appearance obviously played a crucial role. So, for instance, a white person was defined as “a person who (a) in appearance obviously is a White person, and who is not generally accepted as a Coloured person; or (b) is generally accepted as a White person and is not in appearance obviously not a White person”.1 It follows that the body of the individual was read as a signifier of racial identity, a hermeneutic practice still prevalent in present-day South Africa. My argument in this essay is that Zoë Wicomb’s David’s Story2 shows how the trope of “pure blood” in the discourse of race not only reduces the body of the individual coloured person to a material sign of racial difference, but also inscribes a history of shame on that body.

The liminal space is used as a means of figuring and reading artworks that appear to be in a process of becoming and disappearing. A dialectical and reciprocal reading is made of Bourgeois’ “neo-Baroque” artwork Spider (1997) and Michelle Key’s Betwixt-in-Between (2004). Liminality here is discussed within the theoretical framework of several key conceptual concerns, including abjection (as examined principally by Julia Kristeva), Baroque thought (as discussed by Mieke Bal, Gilles Deleuze, Jacques Lacan and Slavoj Žižek) and allegory (as figured primarily by Walter Benjamin and commentators on Benjamin’s writings). What links these concerns are their focus on indeterminacy, instability, and process as opposed to certitude and finitude. The exploration of the inscription of time in space; that is the temporal process, which gives rise to, which produces, the spatial dimension, is attempted in order to make meaning, however provisionally, of what may be argued to destabilise meaning and to consider possibilities for both art-making and interpretation that would engage critically with this instability.

- Description: This thesis presents an investigation of the 4-methoxypyrrolic constituents of two South African marine invertebrates, the nudibranch Tambja capensis and the bryozoan Bugula dentata. Three known compounds tambjamine A (7), tambjamine E (13) and the tetrapyrrole (15) were isolated during this investigation. All three compounds were shown to be active against oesophageal cancer in accordance with the general anticancer and immunosuppressive properties observed for 4-methoxypyrrolic natural products. Tambjamine A (7), tambjamine E (13) and the tetrapyrrole (15), together with tambjamine K (21) and L (22) (previously isolated in our laboratory) were used as standards to quantitatively assess the presence of these tambjamines in T. capensis and B. dentata collected from three different sites along the South African coast. This study confirmed that B. dentata is the source of the 4-methoxypyrrolic natural products sequestered by T. capensis and eliminated the closely related bryozoan B. neritina as a source of these metabolites. The paucity of tambjamine L (21) and K (22) obtained in previous investigations of the sequestered chemistry of T. capensis prompted an attempt at the development of synthetic methodology that could be used to synthesize tambjamines in sufficient yield for in depth bioactivity studies. In order to by pass the extensively reported problems associated with the synthesis of this group of compound 3-methoxy-2-formylpyrrole (47), readily accessible from 3-methoxypyridine N-oxide (48), was used as the starting material in a singlet oxygen induced 2,2’ bipyrrole coupling reaction. Although 47 proved unreactive in this coupling reaction, when the N-Boc protected analogue of 47 was used, and the reaction worked up in the dark, the novel methyl 4-aza-5-oxo-6,6-di-(2-pyrrolyl)-2(Z)-hexenoate (57) was obtained in low yield. The physical properties of tambjamine (E) (13) and the tetrapyrrole (15) were investigated to further the understanding of the proposed oxidative DNA cleavage mechanism and to determine the potential of the 4-methoxypyrrolic natural products as photodynamic therapy agents.

- Description: Although several nitrification/denitrification processes are established for the removal of ammonia and nitrate from municipal and industrial wastewaters, there are few reported results on the removal of these ions from metal-processing and finishing wastewaters. Unlike municipal wastewater, there is very little organic content in metal-processing wastewaters. Sources of ammonia and nitrate in the wastewater include the use of ammonium-nitrate-fuel oil as a blasting agent, and the use of other nitrogen-containing reagents during processing. The objective of this work was to investigate a biological process for the removal of nitrogenous compounds from real metal-processing wastewater. The system comprised an aerobic continuously stirred tank reactor (CSTR) followed by an anaerobic packed column and was run using real wastewater from a metal-processing operation. The system was inoculated using humus sludge from a municipal trickling filter and a period of approximately four weeks was required for a denitrifying biofilm to develop. Results showed that ammonia removal occurred readily in the CSTR while nitrite oxidation was slower to develop. The CSTR was found to be suitable for ammonia oxidation; up to 89% ammonia removal was achieved. By employing an integrated process comprising nitrification and denitrification, high ammonia removal efficiencies can be obtained. An effluent that is low in ammonia can be obtained with this system with additional carbon introduced after the CSTR.

- Description: Although several nitrification/denitrification processes are established for the removal of ammonia and nitrate from municipal and industrial wastewaters, there are few reported results on the removal of these ions from metal-processing and finishing wastewaters. Unlike municipal wastewater, there is very little organic content in metal-processing wastewaters. Sources of ammonia and nitrate in the wastewater include the use of ammonium-nitrate-fuel oil as a blasting agent, and the use of other nitrogen-containing reagents during processing. The objective of this work was to investigate a biological process for the removal of nitrogenous compounds from real metal-processing wastewater. The system comprised an aerobic continuously stirred tank reactor (CSTR) followed by an anaerobic packed column and was run using real wastewater from a metal-processing operation. The system was inoculated using humus sludge from a municipal trickling filter and a period of approximately four weeks was required for a denitrifying biofilm to develop. Results showed that ammonia removal occurred readily in the CSTR while nitrite oxidation was slower to develop. The CSTR was found to be suitable for ammonia oxidation; up to 89% ammonia removal was achieved. By employing an integrated process comprising nitrification and denitrification, high ammonia removal efficiencies can be obtained. An effluent that is low in ammonia can be obtained with this system with additional carbon introduced after the CSTR. The gravel-packed column reactor was found to be unsuitable for the removal of nitrate in the configuration used (maximum 15% removal efficiency). The critical parameters for denitrification are nitrate concentration, temperature, influent flow rate and mean cell retention time. Nitrate removal did not meet the expectations projected by previous authors' work using synthetic wastewater.

- Description: Carpenter, Argyrozona argyrozona (Valenciennes, 1830), is an endemic South African sparid fish. They form an important component of the commercial linefishery on the South African east coast, where they are the third most important species landed. Recent investigations revealed that the catch per unit effort (cpue) of this species has declined markedly since the early 1900’s. Despite these declines and the importance of this resource, remarkably little biological information on this species exists for providing management advice. This thesis investigates the life history of carpenter, particularly those aspects that are used for management. This includes an investigation into the stock distribution and identification of nursery areas, and an assessment of age, growth, reproduction and movement patterns. Age and growth was assessed using methods based on both otoliths and mark-recapture. Transverse sagittal sections from the Tsitsikamma National Park showed clear opaque and translucent growth increments. Marginal growth zone analysis and mark-recapture of chemically tagged fish (Oxytetracycline) revealed that these were deposited on an annual basis: opaque in summer and translucent in winter. A. argyrozona were found to be long lived (up to 27 years) and slow growing. Within reader (between counts) and between readers average percent error (APE) was 5.3 and 1.8, respectively, showing that readability of carpenter otoliths is high. Comparison between whole and sectioned otoliths showed that the former significantly under-estimated the age of fish older than 10 years (p<0.01). A large proportion (68%) of the individual growth rates derived from mark-recapture data were below those predicted by the otolith based von Bertalanffy growth model (p<0.01). This was attributed to the negative influence of external tags, as hydroids, frequently occurring on the tags of recaptured fish, were observed to cause severe lesions and in some cases, extensive fin damage. This brings into question the use of mark-recapture studies to calculate growth of some species. The effects of sampling design and sample size on age and growth estimation were assessed. The minimum sample size required to accurately estimate growth and mortality, and the effects of using either random or stratified sampling procedures were tested. Decimal and integer ageing both produced similar estimates of von Bertalanffy growth parameters, growth curves, spawner biomass-per-recruit (SB/R) and fishing mortality (F) estimates. Sampling monthly throughout the year and collecting data in a single large sample provided similar growth curves, von Bertalanffy, F and SB/R estimates. The data showed that estimates based on less than 300 random samples were unreliable. However, accurate growth parameter estimates were achievable with less than 200 samples if the sample was stratified with 10 or more samples per 2 cm size class. An investigation into the reproductive biology of A. argyrozona within the Tsitsikamma National Park revealed that they were serial spawning late gonochorists. The size at 50% maturity (L₅₀) was estimated at 292 and 297 mm FL for females and males, respectively. Both monthly gonadosomatic indices and macroscopically determined ovarian stages strongly suggest that A. argyrozona within the Tsitsikamma National Park spawn in the austral summer between November and April. The presence of post-ovulatory follicles (POF's) confirmed the six month spawning season, while monthly proportions of early (0-6 hour old) POF's showed that spawning frequency was highest (once every 1-2 days) from December to March. Although spawning season was more highly correlated to photoperiod (r = 0.859) than temperature (r = -0.161), the daily proportion of spawning fish was strongly correlated (r = 0.93) to ambient temperature over the range 9-22⁰C. Both spawning frequency and season increased with fish length. As a result of the allometric relationship between annual fecundity and fish mass a 3 kg fish was calculated to produce 5 fold more eggs per kilogram of body weight than a fish of 1 kg. In addition to producing more eggs per unit weight each year, larger fish also produce significantly larger eggs. Adult emigration and larval dispersal of A. argyrozona from the Tsitsikamma National Park (TNP), South Africa, were investigated using mark-recapture data and Acoustic Doppler Current Profiler measurements of currents. Tagging data showed that adult carpenter were mainly resident, with a small proportion (7%) leaving the TNP in both easterly and westerly directions. No relationship was found between fish movement patterns and fish size or time-at-liberty. Current patterns suggest that eggs and larvae spawned within the TNP are mainly transported eastwards towards established nursery grounds; the median estimated distance moved was 299 km (range 42-561 km) in 30 days (time to flexion). Given this pattern of ichthyoplankton dispersal together with the fact that adult carpenter within the TNP display a high degree of residency and that they are much more abundant than in adjacent fishing grounds (cpue = 23 times greater), it appears that the TNP protects a viable carpenter spawner population capable of seeding adjacent fishing grounds. Fishery independent biomass surveys and commercial linefish catch returns were used to elucidate the spatial patterns of A. argyrozona distributed along the South African continental shelf. Two distinct areas of abundance were determined, one on the central and the other on the eastern Agulhas Bank. Tagging studies revealed little exchange between them. Two distinct nursery areas were identified. These data suggest that in each area juvenile A. argyrozona settle and move inshore, and then move offshore as they grow. Otolith readability and growth rates varied between regions, with fish from the Eastern Cape having the lowest average percentage error and the slowest growth rates, readability decreased westward. L₅₀ varied between the central and eastern Agulhas Bank as did mass at length. Based on the distribution of carpenter, variability in otolith readability, mass at length, variation in growth and size at maturity, it is concluded that carpenter exist as two separate stocks, one on the central Agulhas Bank and the other on the eastern Agulhas Bank. SB/R, fecundity-per-recruit (Egg/R) and yield-per-recruit (Y/R) models were used to model both South African carpenter stocks. Owing to the allometric relationship between annual fecundity and individual size, Egg/R ratios were between 40 and 74% of SB/R at equivalent F. Egg/R ratios account for allometric increases in fecundity with size/age, and are therefore regarded as more accurate estimates of reproductive potential, and biological reference points for per-recruit analysis should wherever possible be based on this quantum. It is shown that the current length at first capture (lc) (250 mm TL) and F (at M = 0.1) will reduce Egg/R to 6.41% of the pristine value in the Eastern Cape and between 6.06 and 14.15% on the central Agulhas Bank, indicating that both stocks are heavily over exploited. An increase in lc from 250 to 350 mm TL and a 70% reduction in commercial fishing effort is recommended to attain a target reference point of 40% Egg/RF=0. Bag frequency analysis indicates that a reduction in daily bag limit from 10 to 4 fish.person¹.day⁻¹ would effect an equivalent reduction in recreational F. The trawl bycatch of carpenter is only 3% of the reported line catch, consequently restrictions to this fishery are not recommended.

- Description: preprint , “The identity of the old ANC is changing fast and its soul is becoming harder to locate” – so writes William Gumede in his best-selling account of the Mbeki presidency. This is a thoroughly admirable book, critical, informed and deeply concerned with the welfare of the people of South Africa, especially the poor – with no taint of political hagiography. The central plank of the critique concerns the ANC’s management of the economy. Gumede’s account of the genesis of GEAR and the devious way it was sprung on the tri-partite alliance is illuminating. It was done under the rubric of necessary modernization, according to Gumede, and allegiance to the Blair/Schroeder Third Way. But there were huge ancillary consequences: the loss of influence by the ordinary ANC membership, neglect of branch activity, sidelining of the parliamentary caucus, centralization of policy development in the office of the president, increasing reliance on consultants and relentless cosying up to big business.
