  • Description: Before independence Namibia's education system was predominantly teacher-centred. Soon after its independence Namibia embarked on education restructuring and transformation. A new education system, leamer-centred education, was introduced to cater for the needs of all Namibian learners. It was seen as an effective antidote to the stifling teacher-centred practices of the previous education system. A new programme, the Basic Education Teacher Diploma (BETD) was introduced to prepare teachers to teach in a leamer-centred approach. Research has, however, indicated that many Namibian teachers have a somewhat shallow or naIve understanding oflearner-centred education. This small-scale case study, conducted in Oshikoto region, focuses on two Grade 4 teachers. The study examined the two teachers ' perceptions and experiences oflearnercentred education and the teaching strategies they use to develop learners' understanding. The study uses a qualitative approach in its exploration of teachers ' lived experiences of becoming learner-centred. The data emerging from this case study identify a number of misconceptions and understandings of leamer-centred education and its implementation. The findings suggest that teachers ' misconceptions are caused by a lack of deep understanding about the epistemology and theory of learning which underpins Namibia's reform policies and principles.

Selecting stories to tell: the gatekeeping of international news at SAfm

  • Description: The premise of this thesis is that the selection of international news to be aired on the bulletins of SAfm by SABC Radio News staff is influenced by more complex factors than could be seen solely from the prism of an empirical journalistic paradigm. Drawing from data obtained through participant observation and interviewing, it is noted that there has been a revolution from a propagandist approach during apartheid to a professional approach following the demise of apartheid, in the selection of international news for bulletins on SAfm. Using Lewin's theory of forces in decision making and locating it within four out of five levels of a framework of gatekeeping analysis provided by Shoemaker (1991) and Shoemaker et al (200 I), it is concluded that the delimiting well-tested routines of newsmaking act as powerful companions of individuals' selection decisions of international news broadcast on SAfm's bulletins. However, these routines are adapted to meet the organisational demands of the SABC, which as a Public Service Broadcaster (PBS) has embraced the discourse of South African nationalism/panAfricanism, as a major philosophy underpinning the Corporation's coverage of the world. Therefore, some individual, routine and organisational factors influencing the se lection of international news broadcast on SAfm's bulletins, are predetermined and co-determined by the social system (the ideological/discursive structure), which is promoted by certain social institutions. Instances of spokespersons of such institutions as governments, international governmental and non-governmental organisations, etc., officiating the news abound; the gatekeepers use them to meet routine professional standards of journalism. This potentially works to sustain the hegemonic discourses of the powerful in international affairs (in tenns of core/peripheral nations relations, and elite classlruled majority relations) though there is a conscious oppositional effort to modify or dwarf stories that explicitly promote imperialism and to hold rulers accountable to the public. It is posited that the time is ripe for newsworkers responsible for the production of bulletins for SAfm to take the risk that may be necessary to inject a few changes in routine practices that could limit the engineering of consent to the powerful elites in the international arena.

  • Description: Presently in the South African automotive industry competition is becoming more fierce. It is becoming more important for companies to concentrate on thier competitive strategies to ensure that they remain competitive in this industry. Military strategy techniques have always been successful in defeating an anemy opponent. An enemy in a military sense could be considered as a competitor in a business sense. There is currently a potential for an improvement of the competitive strategies that South African organisations, in particular the South African automotive industry uses to remain competitive. Military strategists such as Sun Tzu and Carl von Clausewitz have provided valuable strategy theories and philosophies to many military institutions. Military strategies such as Attrition and Maneuver have long been used by these institutions in battle to defeat the enemy. Military strategies could provide the edge that companies ranging from manufacturers, suppliers of components and dealerships need, to remain competitive in the automotive industry.

  • Description: During the apartheid era, that is, before 1994, the education management system in South Africa was fragmented, authoritarian and top-down. Principals were expected to manage schools on their own without consulting the rest of the staff. The birth of political democracy in 1994 resulted in many changes in the education system. These changes include the creation of one national department. In line with this democratisation came the concept of school management teams (SMTs). Because of the democratic nature of this kind of a structure (SMT), it is required that educators work co-operatively and as a team. This has been problematic in some schools where the principal has traditionally felt comfortable taking decisions on his or her own without any input from relevant stakeholders. Furthermore, through the legacy of apartheid, teachers themselves have dogmatically been oriented to being the recipients of instructions and to view management as the prerogative of the principals only. The formalisation of SMTs thus brings new challenges to both principals and staff members, essentially the notion of democratic or team-management. The object of this study is to find out how the concept of democratic management is being received. This study includes all the government-aided high schools in Grahamstown (ten of them). Studying all 10 high schools - 6 from the local township, 3 ex-model C schools, and 1 from the coloured township – has produced a broad and varied picture of how SMTs are being received in Grahamstown secondary schools. The study was framed within the interpretive approach, and sought to unpack the perceptions of SMT members with regard to SMTs. An interpretive paradigm made it possible for me to gain an in-depth understanding of SMT members’ perceptions of team-management within their contexts. I used questionnaires, interviews and observation as research tools to gather data. This study has found that, although the concept of team management is well-received, there are significant obstacles to the acceptance of teamwork as an alternative form of management. Many of these may be the result of decades of disempowering governance strategies, resulting in impoverished notions of school ownership and joint responsibility. Some relate to the political nature of schools as organisations. Despite these problems, the study has confirmed that team-management is the preferred approach for a variety of reasons. Team-management usually results in enriched decision-making, the sharing of responsibilities and higher levels of support. A major systemic shortcoming highlighted by the study is the absence of meaningful training in democratic educational management.

The life history patterns of the polychaete, Terebrasabella heterouncinata, a pest of cultured abalone

  • Description: Terebrasabella heterouncinata is a small K-selected sabellid polychaete. It is a simultaneous hermaphrodite with a semi-continuous mode of reproduction, producing relatively few large eggs that are brooded within the parental burrow until the larvae emerge, to settle on the growing edge of the abalone shell. Despite its low fecundity, this worm has become problematic on abalone farms in South Africa. The present study was conducted to gain an understanding of the life history patterns of T. helerouncinata to determine how they contributed to the success of these worms under altered conditions. This study demonstrated that conditions prevalent on abalone farms were conducive to enhancing the reproductive success of this worm, and suggests that larger, more fecund worms may have been selected for in the decade that these worms have been present on the farms. Increased nutrient availability, and possibly the increased stability of the farm environment relative to its natural environment, has led to a 1.5-fold increase in the average size of the worms. Body size was found to be positively correlated with brood size, and this resulted in worms on farms brooding 3 to 4.5 times more offspring at a time than worms from wild abalone. The ability to increase the number of eggs produced at a time may have been limited by the fact that these worms have only two ovaries. Thus, the increase in fecundity may have been related primarily to the increase in the rate at which the eggs were laid by the worms on the farms, and the increase in the coelomic space available for the storage of these rapidly developing eggs. The ability to increase the rate at which oocytes develop may be related to the vitellogenic mechanisms employed by these worms. Vitellogenic oocytes are able to incorporate high molecular weight yolk precursors from the surrounding coelomic fluid through endocytotic activity. This may allow the oocytes to increase the rate at which they incorporate yolk material under conditions of nutrient enrichment. The increase in fecundity did not occur at the expense of offspring size and, presumably, quality. The increased reproductive output on the farms was compounded by a proportionate increase in the number of reproducing worms within the population. In addition, these worms are long-lived (worms from farmed abalone reached a maximum age of approximately 40 months) and exhibit negligible senescence. Thus, their reproductive output did not change significantly with an increase in age. Furthermore, the proportion of the reproductive worms did not decrease with an increase in age. Thus, within the age range tested, worms of all ages have the potential to make equal contributions to population growth. While diet and abalone stocking density could not be identified as having a significant effect on reproductive output and infestation rate under intensive culture conditions, it was demonstrated that in a naïve abalone population, the total intensity of infestation increased exponentially with time. This increase may be a consequence of an increase in fertilisation success. These worms continuously produce entaquasperm that are released into the water column. The sperm are collected by other individuals that then store the sperm in a single spermatheca. The ability to store sperm relieves individuals of a dependence on the synchronisation of spawning of eggs and sperm. As the population size and density increases, there could be more individuals releasing sperm into the water column, resulting in a continuous supply of sperm. The increased production of eggs would therefore not be constrained by a lack of sperm. The stored sperm are released into the brood chamber to fertilise eggs as they are laid, and this would probably increase the fertilisation success in the species. This study also provides evidence to suggest that reproduction in this worm has a seasonal component. Future studies should concentrate on measuring fertilisation success in greater detail, measuring the effect of season on reproduction, determining whether there are genetic differences between worms on farmed and wild abalone and determining whether wild worms have similar life-spans and age-related fecundity as worms on farms.

  • Description: This study reports the findings on the effect of Microcystin-LR (MCLR) on the gastrointestinal tract cells of mice and on two different cell lines, Caco2 and MCF-7. The cyanobacterium Microcystis aeruginosa produces the potent toxin, MCLR. This toxin has been implicated in a number of cases of ill-health. It was decided to investigate whether microcystin-LR induced apoptosis in the gastrointestinal tract of mice and also which possible mechanisms were involved in the induction in vitro. Balb/c mice were given a 75% LD50 intraperitoneal dose of pure microcystin -LR and sacrificed at 8, 16, 24 and 32 hours post-exposure. The small intestinal sections were stained with haematoxylin and eosin and examined for apoptotic cells. There was a time-dependent increase in the number of apoptotic cells with most in the duodenum and the jejunum. No change in glycogen content was evident at 24 hours post exposure when PAS-stained sections were examined. To determine that microcystin was the agent responsible for the changes, fluoroscein isothiocyanate (FITC) immunostaining for the toxin was done on the sections. Apoptosis in vitro was investigated in Caco2, a cell line that behaves like normal enterocytes when the cells are differentiated at confluency, and MCF-7, a breast cancer cell line deficient in pro-caspase-3, cells by 3-[dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays and by staining with DAPI and Rhodamine 123. MCLR exposure induced apoptosis, as seen in decreased cell viability and increased leakage of LDH, as well as mitochondrial damage shown by Rhodamine staining. The MCF-7 cells, deficient in pro-caspase-3, and Caco2 cells did not show cleavage of poly(ADP)ribose polymerase (PARP) after exposure to 50μM MCLR after 72 hours exposure. Both micro- and milli-calpain activity was however significantly increased in both cell lines exposed to the toxin. There was a significant increase in H2O2, one of the key reactive oxygen species, production during the first 30 minutes that the cells were exposed to 50 mM MCLR.

An examination of dreams and visions in the novels of Virginia Woolf

  • Description: This thesis explores the importance of the visionary experience in five novels by Virginia Woolf. In her fiction, Woolf portrays the phenomenal world as constantly changing and she uses the cycles of nature and the passing of time as a terrifying backdrop against which the mutability and transience of human life are set. Faced with the inevitability of change and the fact of mortality, the individual seeks moments of permanence. These stand in opposition to flux and lead to the experience of a visionary intensity. Woolf's presentation of time as a qualitative phenomenon and her stress on the importance of memory as a function which allows for the intermingling of past and present make possible the narrative rendering of moments which contradict perpetual change and the rigours of sequential time. Moments of stillness 'occur in the midst of and in spite of process and allow for individual contact with an experience that defies the relentless progression of time. Necessary for this experience is not only memory but also the imagination, a faculty which has the power to perceive patterns of harmony in the midst of the chaos that characterises the phenomenal realm. Fundamental to Woolf's writing, however, is the acknowledgement that visions are fleeting, as are the glimpses of meaning that emerge from them. Therefore, while several of her novels describe the artistic effort to create a structured order as a defense against change, Woolf uses the artist's struggle as a metaphor for the difficulties attached to describing the enigma that is life. None of her artist figures is able to formulate a construction that either sums up life or provides a permanence of vision. This study presents a chronological examination of the novels in order to demonstrate that the changing forms of Woolf's fiction trace the evolution of a style that accurately portrays both the workings of the human mind and the insubstantial and fragmentary nature of life. The chronology also reveals that her novels develop in terms of their presentations of the visionary experience. Woolf's final novel incorporates into its central vision the paradoxical fact of the permanence of time's progression and acknowledges that, beyond the individually mutable life, is a continuum that links pre-history to the future. This notion, which is explored in part in the earlier novels, but developed completely in Between the Acts, suggests that consolation can be found in the greater cycles of existence despite the fact of individual mortality.

  • Description: From Introduction: In geography during the 1950's there was a definite move away from the study of unique phenomena to the study of generalized phenomena or pattern (Mather and Openshaw, 1974). At the same time interrelationships between phenomena distributed in space and time became the topic of much interest among geographers, as well as members of other disciplines. The changing emphasis initiated acceptance of certain scientific principles (Cole, 1973), and mathematical techniques became the recognized and respected means through which objective analysis of pattern, structure, and interrelationships between a really distributed phenomena could be achieved (Ackerman, 1972; Burton, 1972; Gould, 1973). Geographers, as do members of other disciplines, frequently borrow mathematical techniques developed for problems encountered in the pure sciences and apply these techniques to what are felt to be analogous situations in geography.

  • Description: The introduction provides a concise discussion of the confused condition of our Western sexuality. It is noted that this confusion has also manifested itself in ecclesiastical circles, and that the contribution of the church towards the resolution of 'moral' confusion in this sphere is in fact minimal. The study then proceeds to a more empirical investigation of certain phenomena which might enable us to demonstrate the close relationship which exists between the individual's psychological condition, or 'state of consciousness', and the type of theology or ethics he formulates or adopts. The present study was an investigation designed to determine whether Anglican clergy and Pentecostal pastors differed significantly with regard to theological orientation, level of self-actualization or the degree of flexibility they showed in the application of sexual values. Furthermore we were concerned to discover the inter-relation between these various traits. A third group of ordinands from St. Paul's College (C.P.S.A.) was also incorporated into the study. All forty eight subjects completed a series of tests and questionnaires which were scored according to eighteen different scales relating to selfactualzing traits, theological orientation and the application of sexual ethics. In brief the results showed that the Anglican clergy were significantly more self-actualizing, theologically liberal and more flexible in the application of sexual values than were Pentecostal pastors. Little difference was found to exist as a function of age and education, or between Anglican clergy and ordinands. Furthermore theological conservatism, general conservatism, dogmatism and inflexibility in the application of sexual ethics were all shown to correlate negatively with self-actualization. In the discussion of results the writer attempted to demonstrate the close relationship between the churchman's psychological make-up and the way in which he construes his world and formulates his theology and ethics. In the concluding discussion the writer once again widened the scope of concern in order to demonstrate how the findings of the present study can be fitted into the broader context of the life of the church. It has been suggested that the type of approach adopted by churchmen to problems of sexuality is very much determined by their psychological make up. Hence in this sense both the status of the church in modern society and the degree to which the church can assist in the resolution of our culture's problems in the field of human sexuality, is greatly dependent upon the 'states of consciousness' of our clergy.
