- Description: Regular strike action has become a central characteristic of the South African industrial relations system. Whilst in the 1950s strikes were mostly isolated outbursts of relatively short duration, strikes in the 1980s were challenges of unprecedented duration and intensity. It is argued that despite this dramatic change, reflecting a series of discontinuities in both the political and economic arenas, strike action in South Africa does follow distinct patterns, and can be ascribed to a combination of identifiable causes. Principal causal factors include wage aspirations, past experiences and the subjective interpretation thereof, and the role of the union movement. Contingent factors include the prevailing political climate, industrial relations legislation, the amount of information opposing sides possess of their adversaries' intentions as well as spatial issues, such as the internal dynamics of individual communities. Partially as a result of South Africa's political transformation, the late 1980s and early 1990s saw further changes in the industrial relations environment. Reflecting these developments, it is argued that a new type of trade unionism has developed, "coterminous unionism" . This will have far-reaching implications for the nature of industrial conflict. However, it falls fully within the theoretical parameters outlined in this thesis. Despite significant developments in social theory in the 1980s and 1990s, there have been few attempts accordingly to update theories of strike action. One of the objectives of this thesis has been to attempt such an update. It is hoped that the constructs developed will shed light on a widely prevalent form of social conflict, assist in the analysis of future outbreaks, and enable the identification of those situations where a high propensity to engage in strike action may exist.

- Description: The Labour Party was a prominent political party amongst coloured people for more than twenty-five years. Formed in 1965 to contest elections for the Coloured Persons' Representative Council (CRC), the Labour Party at the outset adopted an anti-apartheid, anti-separate representation and anti-eRe stance. During the first five years of its existence, the party tried to muster coloured support for its policies. Its promise to cripple the CRC by refusing to occupy seats in the council became the rallying call. The Labour Party won a majority of the elected seats in the first CRC election in 1969 but the government nominated progovernment candidates to all the nominated seats, depriving the Labour Party of an overall majority. Thwarted in their bid to "wreck" the CRC, Labour Party members instead took their seats in the council, vowing to destroy it from within. For the next five years the Labour Party pursued a policy of "confrontation. " By using a "boycott" strategy, it not only hamstrung the effective working of the CRC but thwarted the government in other areas of its "coloured" policy. In the 1975 election the Labour Party won an outright victory, giving it the power to cripple the CRC. However, it did not seize this opportunity. Its decision to "govern" in the CRC constituted a decisive step in the change from confrontation to cooptation. The Labour Party's continued support of the CRC drew widespread criticism from supporters and opponents alike. Its leaders tried to hold together a disaffected party and eventually agreed to the dissolution of the CRC in 1980 in an effort to paper over the cracks in party unity, and to forestall growing coloured opposition to the CRC at the next election. In 1983, the Labour Party displayed a decisive shift in its anti-separate representation stance by lending support to the tricameral system. By doing so, it laid itself open to the same charge of collaboration it had levelled at the other CRC parties. This thesis will examine the history of the Labour Party from its formation in 1965 as an anti-government party, to one of cooperation with its erstwhile opponent by 1984.

Constituent processes contributing to stress induced β-carotene accumulation in Dunaliella salina

- Description: The alga Dunaliella salina possesses the unique ability to accumulate up to 14 % of it's dry weight as β-carotene in response to stress conditions. This hyper-accumulation of β-carotene has led to the commercial exploitation of this alga for the biotechnological production of this important carotenoid. In order to maximise β-carotene production, a dual-stage process which separates the distinctive growth phase from the β-carotene accumulating stress phase has recently been patented. Preliminary laboratory studies showed that although stress factors such as high salinity and nutrient limitation enhance β-carotene accumulation in D. salina (± 10 pg.cell⁻¹), high light intensity was the single most important factor contributing to the induction of β-carotene accumulation in this alga (± 20 pg.cell⁻¹). Moreover, it was demonstrated that β-carotene accumulation can be further stimulated by exposing the alga to a combination of high light intensity, salt and nutrient stresses (± 30-60 pg.cell⁻¹). The response of D. salina to stress was shown to occur in two phases. The first phase occurred within 24 hours and was characterized most importantly by higher rates of β-carotene accumulation for all the stresses investigated. In cells exposed to multiple stress factors in mass culture, the β-carotene accumulation rate was as much as 9.5 pg.cell⁻¹.day⁻¹ in the first phase compared to only 3 pg.cell·day⁻¹ in the second phase. Since the rate of β-carotene accumulation was higher within the first 24 hours after exposure to stress, the first phase was considered crucial for stress-induced β-carotene accumulation. Characterization of this phase revealed that the stress response was multifaceted. Transition of cells from the growth stage to stress conditions was characterized by the following: 1) Change in cell volume. Hypersalinity caused cell shrinkage while cells exposed to nutrient limitation and/or high light intensity caused cells to swell. Restoration of cell volume was shown to occur within 8 hours for all stresses investigated. 2) Altered photosynthesis. Inhibition of both carbon fixation and oxygen evolution was demonstrated in cells immediately after exposure to multiple stress factors. 3) Production of abscisic acid. Intracellular ABA levels increased within 6-8 hours after exposure to all stresses investigated. The rise in intracellular ABA levels coincided with an increase or return to starting cell volume. High intracellular ABA levels were however transient and within 24 hours ABA began to partition into the culture medium. 4) Change in pigment composition. Changes in xanthophyll cycle pigment content was demonstrated soon after exposure to stress conditions. In hypersalinity shocked cells, initial epoxidation of zeaxanthin to violaxanthin and subsequent de-epoxidation to zeaxanthin occurred, whereas exposure to high stress resulted in an immediate and continued decrease in the epoxidation state indicating accumulation of zeaxanthin. A rapid rate of chlorophyll depletion was also demonstrated. In addition to the above responses a rapid decrease in growth rate during this phase was also noted. An interrelationship between cell volume change, ABA production, maintenance of xanthophyll cycle operation and β-carotene accumulation therefore appeared to exist. ABA production was shown to be stoichiometrically related to changes in xanthophyll content with r² = 0.84 and slope of the curve = 0.91 being achieved for high light stressed cells. This study therefore presents strong circumstantial evidence in support of a carotenoid origin for ABA in Dunaliella. In addition, enhanced β-carotene content was achieved by the application of exogenous ABA and related compounds suggesting a role for ABA as a regulator of the overall stress response. Furthermore, zeaxanthin accumulation was shown to be positively correlated ( r²≥ 0.81) to β-carotene accumulation for all the stresses investigated. The second phase was characterized by a return to homoeostasis of the physiological processes mentioned above, indicating acclimation of the cell to prevailing conditions. This stage was characterised by continued β-carotene accumulation and a decreased epoxidation state of the xanthophyll cycle which together appeared to sustain photosynthesis, allowing this organism to tolerate stress conditions.

- Description: This study explores severe mental illness in a South African ru~al district, moving, as with a zoom lens, from the macroperspectives of (i) Xhosa culture, and (ii) biomedicine, to the lived experience of the individual. Its methodology, predominantly qualitative, employed anthropological and psychological procedures. The fieldwork (1988-1989)encompassed a three month stay in the village of Msobomvu. Patients continued to be tracked informally until June, 1995. The empirical research has three parts. In part one, the person with a mental illness was contextualized within Xhosa cosmology and social attitudes. The cognitive and social ecologies were tapped through the narratives of high school and university students at different stages of a Western-biased education. Social attitudes regarding mental illness, and confidence in treatment by traditional healers and the hospital, were also evaluated. Traditional attitudes and supernatural beliefs of illness causation persisted in spite of Eurocentric education, with a concurrent increase in the acceptance of Western-type causal explanations commensurate with continued education. Part two considered the the patients in relation to (i) the biomedical framework (the mental and local hospitals), and (ii) their readjustment to the community after hospitalization. Data came from patient charts, interviews with medical staff, and follow-up visits in the villages. Socio-political and economic issues were salient. Part three case-studied people identified by the village residents as having a mental illness. Resources for treatment - traditional healers, mobile clinic, and village health workers - were the focus. The traditional healing system, and biomedicine, were compared for effectiveness, through the course of illness events. While biomedicine was more effective in containing acute psychotic episodes than treatment by the traditional healer, lack of appropriate resources within the biomedical setting had disastrous results for patient compliance and long-term management of the illness, particularly in people with obvious symptoms of bipolar disorder. The mental hospital emerged as an agent of control. While Xhosa culture provided a more tolerant setting for people with a mental illness, the course of severe mental illness was by no means benign, despite research suggesting a more positive outcome for such conditions in the developing world.

- Description: Citrus is among the most important fruit crops worlstwide, and therefore the preservation and improvement of citrus germplasm is of the essence. Citrus breeders are often faced with the difficulty of distinguishing between new and existing cultivars because of the ambiguous nature of morphological traits due to environmental influences and error in human judgement. The protection of new varieties is very important to the breeder. New varieties cannot be patented in South Africa, but it can be protected by Plant Breeders' Rights, only if it is genetically distinguishable and significantly different economically from existing varieties. Cultivars in four genera (c. sinensis, C. paradisi, C. grandis and C. reticulata) included in the Citrus Improvement Programme (CIP) or cultivars awaiting recognition of Plant Breeders' Rights by the International Union for the Protection of New Plant Varieties (UPOV) were analyzed with Isoenzymes, Restriction Fragment Length Polymorphism (RFLP) and Random Amplified Polymorphic DNA (RAPD). Five enzyme systems (PGM, PGI, MDH, GOT and IDH) were analyzed and founded to be suitable for grouping together cultivars belonging to the same genera. It was not suited for routine discrimination of cultivars in a particular genus. RFLP studies were conducted on five grapefruit cultivars, using cDNA clones from a genomic library of Rough Lemon. RFLP studies were valuable for the discrimination of closely related cultivars which probably originated from a common ancestor by bud mutations. This technique was, however, abandoned due to its biohazardous nature and replaced by the PeR-based Random Amplified Polymorphic DNA. RAPDs are easy to perform and gave promisin& results which were exploited to reveal polymorphisms between cultivars within the various groups. Although the interpretation of data produced by this method is often suspicious, it is the best method currently available for cultivar identification. It can playa complementary role in the protection of new varieties when classical morphological interpretation of differences is not capable of determining sufficient distinctness for the awarding of Plant Breeders' Rights.

- Description: Ever since the earliest times much emphasis has been placed on the physical appearance of women. Particularly in western cultures idealized images of perfection are constantly promoted and the message that comes across in various media outlets is that a woman ought to have a 'perfect' appearance in order to be competent and desirable. This puts a great deal of stress on women and particularly on adolescent girls who are going through a phase of increased sensitivity about their appearance. The literature suggests that people, and women in particular, are fundamentally affected by the way they view their bodies. The body image furthermore has a strong relationship with the self concept, which affects other areas of a person's life such as her academic achievement and her social 'life. Against this background an attempt was made in this study to determine the relationship between the body image of adolescent girls and their academic achievement, their sport participation and their social involvement. The subjects were 180 girls drawn from two rural secondary schools. The survey involved the completion of two questionnaires, namely an adapted form of the Physical Self Subscale of the Tenessee Self Concept Scale (used to determine a score for body image) and a questionnaire on social involvement and sport participation, which was drawn up by the researcher. Biographic data as well as academic scores were gathered from school records. Data was analysed statistically by means of the BMDP Software Version 1990: programme (Sun Unix). Pearson's chi square tests of independence, as well as a one-way analysis of variance with co-variate were carried out. The results reveal that the body image and academic achievement of this group of girls are not significantly correlated. There are, however, significant correlations between the body image and social involvement of these girls, between their body image and sport participation, as well as between their social involvement and sport participation. iv These findings have important implications for"'e"ducation and consideration is given to addressing these issues in schools.

- Description: Ever since the earliest times much emphasis has been placed on the physical appearance of women. Particularly in western cultures idealized images of perfection are constantly promoted and the message that comes across in various media outlets is that a woman ought to have a 'perfect' appearance in order to be competent and desirable. This puts a great deal of stress on women and particularly on adolescent girls who are going through a phase of increased sensitivity about their appearance. The literature suggests that people, and women in particular, are fundamentally affected by the way they view their bodies. The body image furthermore has a strong relationship with the self concept, which affects other areas of a person's life such as her academic achievement and her social 'life. Against this background an attempt was made in this study to determine the relationship between the body image of adolescent girls and their academic achievement, their sport participation and their social involvement. The subjects were 180 girls drawn from two rural secondary schools. The survey involved the completion of two questionnaires, namely an adapted form of the Physical Self Subscale of the Tenessee Self Concept Scale (used to determine a score for body image) and a questionnaire on social involvement and sport participation, which was drawn up by the researcher. Biographic data as well as academic scores were gathered from school records. Data was analysed statistically by means of the BMDP Software Version 1990: programme (Sun Unix).

- Description: Recruitment of planktonic larvae into sedentary benthic populations regulates the population dynamics of marine invertebrates. The processes controlling recruitment, however, are poorly understood, and recruitment remains largely unpredictable, which complicates management of exploited shellfish resources. The mussels Perna perna, Choromytilus meridionalis and Mytilus galloprovincialis, found on the south coast of southern Africa, have planktonic larvae and sedentary adult stages. This thesis examines dispersal, settlement and early post-settlement growth and mortality, and their effect on recruitment and demography of intertidal mussel populations in the region of Algoa Bay on the south coast of southern Africa. Temporal and spatial variation in the body mass, density and size structure of mussels, the distribution of bivalve larvae on plankton grids in the nearshore zone and the distribution of a recently introduced invasive mussel, Mytilus galloprovincialis, were examined between 1989 and 1992. Furthermore, data on hourly or daily changes in wind strength and direction, air and sea surface temperatures and low and high tide levels in the study region, were obtained. There were 3-4 peaks in spawning (characterised by an abrupt decline in weight) and settlement activity annually. These peaks varied in exact timing, intensity and duration between sites and over time. However, at a site, spawning was followed by settlement 4-8 weeks later, and there was a significant (P < 0.05) direct correlation between spawning intensity prior to the appearance of a new cohort and the cohort density (settlement intensity). The stochastic spatial and temporal variation in breeding activity was superimposed on a more general pattern of a higher intensity of spawning and settlement in Algoa Bay than on the open coast, and a higher settlement intensity on coastal sandstone shores than on dune rock shores. Spawning was more frequent in winter and spring, and the probability of spawning and settlement peaked around the spring and autumn equinox, if temperature and wind conditions were suitable. Larval behaviour had little effect on their dispersal in the well-mixed nearshore region. Larvae were passively dispersed by currents, and their dispersal range and direction depended on prevailing winds and local topography. The sharp decline in density of recruit and adult M. galloprovincialis with increasing distance from the point of introduction, showed that some larvae were carried by wind generated currents over moderately long distances (-100 km). However, since most (76 %) M. galloprovincialis recruited within 4 km of the parent population, it is possible that larvae become trapped in small gullies and crevices around rocky shores, and have a limited dispersal range. This could explain the link between local patterns of spawning and settlement. The distribution and abundance of settlers on the shore was influenced by larval behaviour and the availability of settlement, substrata. Larvae preferred to settle primarily on foliose coralline algae and migrate to the adult mussel bed when they were larger (0.60-7 mm), but larvae also settled directly on adult mussels, possibly because the amount of coralline algae was limited. Both direct and secondary settlement were considered to be important in maintaining mussel populations since the rate of settlement was low(generally < 60 000.m-2). Cohort analyses showed that prior to maturity post-settlement growth (- 30 mm in 10 months) and mortality rates (60-100%) were high, but varied. When settlement intensity was low this variability uncoupled the relationship between spawning and recruitment intensity. Multiple regression analysis showed that together reproductive effort (gamete output), settlement intensity, growth and mortality prior to maturity, accounted for 76 % of the variance in recruitment into mature adult populations. The low settlement rate coupled with the short life span of mussels « 3 years), meant that populations underwent marked spatial and temporal variations in structure and abundance as settlement intensity varied, but there were consistent general differences between mussel populations on dune rock and sandstone shores in Algoa Bay and on the open coast. It was concluded from these results that, spawning intensity and post-settlement growth and mortality, rather than dispersal, regulated recruitment and the structure and abundance of intertidal P. perna and C. meridionalis populations along the south coast of southern Africa. On the basis of these results it is recommended that species with limited dispersal, variable recruitment and high natural mortality, such as P. perna, should be conserved by protecting a small part of the population in reserves, and controlling utilisation outside reserves to minimize disturbance to local brood stocks. Furthermore, since the potential for reseeding adjacent exploited areas is limited, several small reserves placed at regular intervals along the coast would be more effective than a single large reserve.

- Description: This work attempts to confront certain political problems created by the individualistic bias in psychoanalytic thinking, and the resulting failure to adequately theorise the importance of social processes. The thesis traces the origins of intrapsychic thinking to Freud's initial move from the seduction theory to the Oedipal theory. This development is offered as a prototype for the debates between conceptualisations of childhood traumatisation as a social problem of actual abuse occurring within dermed power relations, and theories which locate pathology purely within internal conflicts occurring inside the individual. Several criticisms of this shift are offered, and it s impact on later theory is considered. Here a contrast is offered between the theoretical approaches of Melanie Klein and Donald Winnicott, arguing for the usefulness of Winnicott's emphasis on environmental factors within psychodynamic theory. The impact of these theoretical approaches is illustrated through a critical evaluation of Freud's case study of Judge Schreber. Additional historical material is brought in to show the importance of environmental considerations ignored by Freud, and contrasting psychodynamic readings of the case are offered. As an alternative to purely intrapsychic approaches, a reinterpretation of certain strands of Critical Theory is then presented. Adorno's theory of the Authoritarian Personality and Marcuse' s concept of One-Dimensional Man are extended using Winnicott's formulations concerning psychological development. This leads to an examination of the question of the relationship between social structure and individual consciousness. Post-structuralist accounts of language and the construction of identity are explored. These are then developed drawing on theories of ideology, language and consciousness, integrating these with Winnicott's developmental theory to offer an alternative psychodynamic understanding of the relationship between social process and psychopathology. An attempt is made to reformulate - the notions of consciousness and the unconscious in terms of the possibilities and difficulties of representation within available social symbolic codes. In conclusion the it is argued that psychology needs to integrate critical social theory and contemporary understandings of the social construction of consciousness in order to become a meaning force in positive social transformation.

- Description: What has come to be labelled as 'the environment crisis' has roots in the structures and orientations of modern societies. True to our modernist ways we call on, or offer, education and research, experts and science, to address our socio-ecological concerns. This study set out to identify research priorities in environmental education from within the institutional setting of a university and within the context of environmental and political change in southern Africa and epistemological shifts in educational research traditions. The emergent research design allowed for a progressive clarification of theoretical vantage point: from an instrumental listing of priorities, through the participatory development of a critical and consensual framework for research, to a reflexive description of a landscape of shifting priorities. I collected data over a 3-year period, in inter alia 38 semi-structured interviews, workshops with some 150 participants, focus group discussions, documents and conferences. Participants' professional contexts included environmental education, natural resource management, social and biophysical sciences, development, formal and non-formal education, funding agencies, academic and non-academic settings. My engagement with the emerging discourses revealed patterns and inconsistencies in participants' views on research, environmental education, change and research priorities. I identified three orientations - Research for Management to Restore Order to Nature and Society, Research to Resolve Practitioners' and Communities' Problems, and Research for Radical Reconstruction - in the emerging landscape. These orientations were accompanied by change models and themes (discourses of difference and 'othering', instrumental views of education and research and accumulative knowledge, a conceptual theory-practice gap) which limited their potential for transformation towards sustainable living. They presented solutions cut from the same modernist cloth as the environment crisis. An emerging Reflexive perspective in and on environmental education research showed potential as a transitionary orientation outside modernist assumptions. I outline research priorities from this perspective. Reflexivity reveals the myths of expert-driven, instrumental and institutionalised research separated from environmental education and based upon rationalistic interpretations of science. It opens up possibilities for transformative knowledge emerging from 're-search' based versions of education as a process of, rather than a means to, social change.

- Description: Over the last thirty years, there has been considerable evolution in the thinking about gender equality issues and the actions needed to achieve real changes in the position of women vis-a-vis men. Prior to the 1970s, women were defined mainly in terms of their conventional reproductive roles, and efforts to improve women's welfare focussed on such programmes as literacy courses, home economics, child care and family planning. Though no doubt valuable, such welfare and family-oriented programmes had the effect of reinforcing women's traditional role in the family. Since the 1970s, there has been a shift to the division of labour based on sex, and the impact of development and modernization strategies on women. It is important to understand that improvements in women's status require analysis of the relations between men and women, as well as the concurrence and cooperation of men. As illustrated in the Beijing document: "Achieving gender equality and empowerment of women requires redressing inequalities between women and men and girls and boys and ensuring their equal rights, responsibilities, opportunities and possibilities. Gender equality implies that women's as well as men's needs, interests, concerns, experiences and priorities are an integral dimension of the design, implementation, national monitoring and follow-up and evaluation, including at the international level, of all actions in all areas."

- Description: Kinetics and equilibria for the reaction between pyridine and cobalt(II) phthalocyanine [CoPc] (H2Pc = phthalocyanine) in dimethyl sulphoxide (DMSO) were studied at 25°C. The complex, CoPc(py)2, is formed in two consecutive steps. The formation of the mono-substituted CoPc(py)(DMSO) occurs first with a pseudo-first-order rate constant of k1f = 7.7 ± 0.3 × 10−3 dm3 mol−1 s−1. The final disubstituted CoPc(py)2 complex is formed with k2f= 1.1 ± 0.1 × 10−4dm3mol−1−1. The equilibrium constants were found to be K1 = 160 ± 20dm3 mol−1 and K2 = 15 ± 3 dm3mol−1 for the formation of CoPc(py)(DMSO) and CoPc(py)2, respectively.

- Description: Solanum sisymbriifolium (sticky nightshade) is a shrubby weed of South American origin that was introduced to South Africa at the turn of the century. Despite being indicative of disturbed habitats, the weed was found to be invasive in conservation, agricultural recreational and suburban areas; this, coupled with the failure of both chemical and mechanical control attempts suggested that the weed was a good candidate for biological control. A biological control programme which followed a standard protocol was initiated. Observations suggested that S. sisymbriifolium dispersed primarily by seeds. Plants produced large quantities of fleshy fruit, favoured by frugivorous birds, which facilitated the rapid spread of the weed into new habitats. The seeds germinated quickly, especially in disturbed soil, often below the parent plant where they dropped from burst fruit, and along fences where birds roost. The pre-introductory survey of the weed revealed that S. sisymbriifolium was attacked by a relatively small number of, mainly polyphagous, herbivorous insects. These were localised and sporadic in incidence and inflicted very little observable damage. The herbivore fauna of S. sisymbriifolium was depauperate even in relation to two other exotic weeds, S. elaeaglllfolium and S. mauritianum, in South Africa. The paucity of native herbivores on S. sisymbriifoliwn was ascribed to a combination of the weed's taxonomic distinctness from South African Solanum species, and the dense covering of glandular trichomes on its leaves. Although it was shown that the exudate produced by these glandular trichomes of S. sisymbriifolium seriously impeded the movement and feeding of native herbivores, there was not enough evidence to suggest that the glandular trichomes, alone could have been responsible the lack of herbivores on the weed. Two leaf-feeding Cassidinae Gratiana spadicea and MetJ-iona elatior were screened as agents for the biological control of S. sisymbrilfolium. Favourable biological characteristics for both species included a high rate of increase, long-lived adults, many generations per year, and a high per capita feeding rate. Host range was investigated in larval survival tests and adult choice tests. The larvae of both species were reared through to the adult stage on several of the native Solanum species tested, and also on eggplant (S. melongena). However, the survival of G. spadicea on the majority of these species was very low, suggesting that the beetles would be unlikely to attack them in the field. This was supported by the adult choice tests, where G. spadicea females displayed, a strong oviposition preference for their natural host. In contrast, M. elatior larvae survived well on non-host plants, and the females selected several non-host species, including eggplant for oviposition. It was argued that the conflict of interests involving eggplant was overrated because eggplant is subjected to a stringent insecticide spray regime. Based on this evidence, permission for release was granted for G. spadicea. The impact of native parasitoid host range extensions to weed biological control agents in South Africa was investigated. Native parasitoids were recorded from nearly half of the agent species that had established on their target weed. The level of concealment and taxon influenced susceptibility of the agents to parasitoid attack Poorly concealed endophagous agents were most susceptible to attack, while exposed feeders were fairly free from attack. However, native parasitoids were reported not to strongly influence weed biological control agent populations and it was concluded that no agent should be rejected based only on its susceptibility to native parasitoid attack. Finally, several predictions are made as to the potential success of G. spadicea on S. sisymbriifolium and some of the challenges facing the biological control of weeds are discussed.

- Description: Solanum sisymbriifolium (sticky nightshade) is a shrubby weed of South American origin that was introduced to South Africa at the turn of the century. Despite being indicative of disturbed habitats, the weed was found to be invasive in conservation, agricultural recreational and suburban areas; this, coupled with the failure of both chemical and mechanical control attempts suggested that the weed was a good candidate for biological control. A biological control programme which followed a standard protocol was initiated. Observations suggested that S. sisymbriifolium dispersed primarily by seeds. Plants produced large quantities of fleshy fruit, favoured by frugivorous birds, which facilitated the rapid spread of the weed into new habitats. The seeds germinated quickly, especially in disturbed soil, often below the parent plant where they dropped from burst fruit, and along fences where birds roost. The pre-introductory survey of the weed revealed that S. sisymbriifolium was attacked by a relatively small number of, mainly polyphagous, herbivorous insects. These were localised and sporadic in incidence and inflicted very little observable damage. The herbivore fauna of S. sisymbriifolium was depauperate even in relation to two other exotic weeds, S. elaeaglllfolium and S. mauritianum, in South Africa. The paucity of native herbivores on S. sisymbriifoliwn was ascribed to a combination of the weed's taxonomic distinctness from South African Solanum species, and the dense covering of glandular trichomes on its leaves. Although it was shown that the exudate produced by these glandular trichomes of S. sisymbriifolium seriously impeded the movement and feeding of native herbivores, there was not enough evidence to suggest that the glandular trichomes, alone could have been responsible the lack of herbivores on the weed. Two leaf-feeding Cassidinae Gratiana spadicea and MetJ-iona elatior were screened as agents for the biological control of S. sisymbrilfolium. Favourable biological characteristics for both species included a high rate of increase, long-lived adults, many generations per year, and a high per capita feeding rate. Host range was investigated in larval survival tests and adult choice tests. The larvae of both species were reared through to the adult stage on several of the native Solanum species tested, and also on eggplant (S. melongena). However, the survival of G. spadicea on the majority of these species was very low, suggesting that the beetles would be unlikely to attack them in the field. This was supported by the adult choice tests, where G. spadicea females displayed, a strong oviposition preference for their natural host. In contrast, M. elatior larvae survived well on non-host plants, and the females selected several non-host species, including eggplant for oviposition. It was argued that the conflict of interests involving eggplant was overrated because eggplant is subjected to a stringent insecticide spray regime. Based on this evidence, permission for release was granted for G. spadicea. The impact of native parasitoid host range extensions to weed biological control agents in South Africa was investigated. Native parasitoids were recorded from nearly half of the agent species that had established on their target weed. The level of concealment and taxon influenced susceptibility of the agents to parasitoid attack Poorly concealed endophagous agents were most susceptible to attack, while exposed feeders were fairly free from attack. However, native parasitoids were reported not to strongly influence weed biological control agent populations and it was concluded that no agent should be rejected based only on its susceptibility to native parasitoid attack. Finally, several predictions are made as to the potential success of G. spadicea on S. sisymbriifolium and some of the challenges facing the biological control of weeds are discussed.

- Description: The fishes of three small Natal estuaries, the Mhlanga, Damba and Zotsha were sampled over a period of two years. A total of 68 fish taxa representing 24 families, 39 genera and 55 species were captured during this study. Forty seven fish taxa were recorded in the Mhlanga estuary of which Gilchristella aestuaria, Oreochromis mossambicus, Valamugil cunnesius, Valamugil sp. and juvenile mugilids numerically dominated. In terms of biomass, O. mossambicus, V. cunnesius, Liza alata, Myxus capensis and Mugil cephalus dominated the ichthyofauna of the Mhlanga system. In the Damba estuary, 24 fish taxa were recorded, the most abundant being Glossogobius callidus,M. capensis and 0. mossambicus. M. capensis, M. cephalus, O. mossambicus and G. callidus dominated the fish biomass captured in the Damba system. A total of 56 fish taxa were recorded in the Zotsha estuary during this study, with the ichthyofauna numerically dominated by juvenile mugilids, G. aestuaria, O. mossambicus, Rhabdosargus holubi, Terapon jarbua, Ambassis productus and G. callidus. The species which dominated the fish biomass in the Zotsha system were 0. mossambicus L. alata, Valamugil robustus, V. buchanani, M. capensis, M. cephalus and V. cunnesius. Classifying the species according to whether they were resident estuarine, freshwater, estuarine-dependent marine or marine species revealed that the first three groups were all well represented in the systems. Oreochromis mossambicus was the dominant freshwater species in all three estuaries. Gilchristella aestuaria and Glossogobius callidus were the principal estuarine species in the Mhlanga and the Damba respectively, with G. aestuaria, A. productus and G. callidus being the dominant estuarine species captured in the Zotsha. The principal estuarine-dependent marine fishes captured in the Mhlanga were V. cunnesius, Valamugil sp., juvenile mugilids, M. capensis, M. cephalus and L. alata. In the Damba, M. capensis and M. cephalus were the dominant estuarine-dependent marine species and in the Zotsha juvenile mugilids, R. holubi, T. jarbua, M. capensis, V. cunnesius, V. robustus, M. cephalus, L. alata and V. buchanani were the principal estuarine-dependent marine species. The results of this study indicate that the estuaries are dominated at different periods by different assemblages of fishes. This is linked to the spawning and migration patterns of the various species as well as the hydrological regime of each estuary. During the winter these systems are normally closed with relatively deep waters and high food resource and habitat availability. Freshwater and estuarine species mainly inhabit the upper reaches of the systems while estuarine-dependent marine species, which dominate the fish community, mainly occupy the middle and lower reaches. When these estuaries open with the onset of the spring/summer rains, adult and sub-adult estuarine-dependent marine species emigrate to the marine environment and juveniles begin recruiting into the systems. Spring is also the peak breeding period of resident estuarine and freshwater species, resulting in an increase in the contribution of these fishes to the overall ichthyofauna during this period. When closed estuaries open the water level falls and this results in the fishes concentrating in the lower reaches of the system where moderate water depths are present, thus further contributing to an increase in the proportion of freshwater and estuarine species in this region. The breaching of closed estuaries also results in a reduction in food resources and habitat availability. Competition and possible increased vulnerability to avian predation (due to the shallow nature of the systems), may contribute to a decrease in the proportion of estuarine and freshwater species in summer. The prolonged recruitment of Of-juveniles of estuarine-dependent marine species results in an increase in the proportion of these fishes present in the estuaries during summer. In autumn, the systems normally close, water levels rise and available food resources and habitat increase. This allows the redistribution of freshwater and estuarine species upstream, leaving estuarine-dependent marine species to dominate the middle and lower reaches. Although temporarily open/closed estuaries along the Natal coast may not be as diverse as permanently open estuaries in terms of their ichthyofauna, their importance must not be underestimated, since by providing a series of sheltered habitats along the coast they may contribute significantly to the viability of estuarine-dependent marine fish stocks. , Rhodes University Libraries (Digitisation)

- Description: Recent collections of fishes from the South Atlantic islands of the Tristan da Cunha Group (Tristan, Inaccessible and Nightingale) and Gough Island have produced 25 new records. Fifty one species are known to occur in the near-shore waters of the islands (46 of these are documented by specimens and another 5 species are probable). A diagnosis, synonymy and in most cases, an illustration, are provided for each species. For certain species, brief notes on biology, relative abundance and seasonal distribution are included. The neritic ichthyofauna of the Subtropical Convergence (STC) region is characterized, and the importance of this frontal zone as a barrier to dispersal of species in the Southern Ocean is evaluated. Analysis of the zoogeographic affinities of the Tristan/Gough fish fauna resulted in a redefinition of the West Wind Drift Islands Province (WWDI), comprising the Tristan Group and Gough in the South Atlantic and St. Paul and Amsterdam Islands in the southern Indian Ocean. Verna Seamount (west of Cape Town) and Walters Shoal (south of Madagascar) are excluded from the WWDI Province, as the affinities of their poorly-known fish faunas appear to be more with South Africa and the tropical Indian Ocean respectively. , Rhodes University Libraries (Digitisation)

- Description: Migrant labour constitutes one of the perennial problems of the political economy of the Southern African region. The movement of people between their home countries and the gold mines in South Africa is over a hundred years old. In this sense, labour migrancy predates apartheid, and is now threatening to outlive it. Migrants working in South Africa make up a sizable proportion of the total wage earning population of the neighbouring countries (Botswana, Lesotho, Swaziland, Mozambique and Malawi). Their entrenched dependence on migrant-based revenue has made them vulnerable to fluctuations in labour flows to the gold mines (Davies, 1992) The developments since the first quarter of 1988 have altered the terms of debate on migrant labour. With the independence of Namibia and the establishment of a new government in South Africa, to name but a few, the pattern of future regional cooperation has become a central issue. Likewise, the debate about labour migrancy has entered a new phase. Given the current political changes, and yet to take place, this study constitutes a modest attempt to contribute to the debate by examining the prospects of restructuring of labour migrancy to the gold mining industry. The central aim of this undertaking will be to establish what the future holds for the foreign component of the labour force. The focus here will be on the emerging debates in this area, policy pronouncements by major stakeholders, the Chamber of Mines and the new Government of National Unity. However, an informed forecast on the future of labour migrancy is possible only if we establish the conditions that created it in the first place; how it has been constructed overtime; and the successive moments of transformation in the system. In this regard, this study will locate the origins and development of labour migration in its proper historical context ~ before drawing conclusions about the future of the system. In this scholarly pursuit one does not pretend to break a new ground but rather to re-interpret the current literature on migration and establish whether the current pattern of labour migration will change. The research will be based mainly on secondary materials, drawing extensively on published materials, journals and articles.

- Description: This study examines the wide-ranging and critical factors which have impacted on the African National Congress' (ANC) emerging foreign investment policy. It identifies and analyses the matrix of political and socio-economic factors which have combined at global and national levels to shape ANC policy perspectives towards foreign direct investment (FDI). In so doing, the study adopts an eclectic theoretical and methodological approach. It draws on various theoretical traditions to propose a framework that is heuristic and contingent, rather than axiomatic. With regard to foreign investment, in particular, it recommends a theoretical pluralism emphasising 'engagement' through praxis and sound political (state) action. The study argues that the ANC has reconsidered many of its basic assumptions on the nature of the post-apartheid economy and discusses the reasons for those shifts. The reasons include, in particular, global political and economic trends and the balance of forces in South Africa. These have combined to ensure the ANC's broad acceptance of an 'open-door policy' towards FDI so long as it occurs on terms not inconsistent with national objectives. The emerging policy sees the state playing an active role in encouraging and guiding FDI to specific areas and sectors supportive of broad-based development. Foreign investors will be encouraged to form joint ventures with emerging black businesses and agree to foster training, skills development and affirmative action. Harnessing the benefits of FDI will be important for the success of wider strategies designed to place the economy on a firmer, more sustainable growth path.
