- Description: Gender-based violence has been recognized as a pressing mental health problem that is prevalent within South African society. Non-governmental organizations play a major role in addressing and highlighting the issue. These organizations make use of volunteers in order to assist in meeting their goals. The modernist perspective has been the dominant investigative mode when research into volunteers has been conducted. However, this study has been conducted with an emphasis on narrative. In its use of this constitutionalist and deconstructive perspective, it examines the identity of the research participants within the dominant social and cultural discourses that story their lives. This presents a major challenge to the modernist framework. In examining the life stories of the participants an emergent nature of identity is noted. Through the process of storying their lives and ascribing meaning to their experiences and understandings, the participants engaged in a process of constructing their identity. This research recognizes that identity is both multi-sited and multi-storied. The emphasis on personal agency enables the participants to restory their lives in the light of challenging prevailing discourses. It is in this process of challenge that they reauthor their lives and are in a position to change their own lives and the lives of others.

- Description: This research report is an edited version of a thesis written by Charlotte van Hees for a Master’s degree in organisational anthropology. The degree was awarded by the University of Utrecht, the Netherlands in May 2000. The fieldwork for her thesis was carried out in the first half of 1999 when Charlotte joined the Institute of Social and Economic Research (ISER) project team investigating development opportunities for local youth. For a town of its size Grahamstown has an exceptionally large number of development organisations and community initiatives. In short, it is the ideal setting for an organisational anthropologist. Over a six-month period Charlotte met with members of local organisations to compile a directory or, as she prefers to call it, a ‘social map’. The social map, published as ISER Research Report No. 3, sets out the manner in which local organisations are linked in their activities and services. Report No. 3 should be read in conjunction with this report. In her thesis Charlotte analyses the ideal characteristics of youth organisations and matches local examples to the ideal. On a ladder of perfection, an organisation run by youth for youth optimises youth development. Youth will benefit most if organisations join forces to offer comprehensive and coordinated services. Charlotte observed that although Grahamstown boasts a large number of organisations serving the youth, their services tend to be fragmented or overlapping. As a young outsider, Charlotte van Hees has the advantage of ‘seeing’ the local maze of organisations from a fresh vantage point. Her sizing up of the local situation has benefited from her considerable experience of youth work in the Netherlands. Apart from theoretical insights the report offers practical guidelines to enhance the success of local initiatives for youth. One recommendation, which youth volunteers might wish to adopt as their project, is to continuously update the social map. South Africa is a country experiencing rapid social change. Charlotte’s analysis is based on time- bound observations and a particular constellation of organisations. There have been major changes in the local government system since the study was written up which will inevitably affect the operations of organisations serving the youth. However, the basic lessons to be learnt from her analysis will remain valid in future and continue to serve as useful pointers for scholars and practitioners. Charlotte revisited Grahamstown briefly in April 2000 to present results to local organisations which had participated in the social mapping research. The workshop participants asked the ISER to make Charlotte’s analysis more widely available to stimulate debate and action among local youth and their organisations. It is in response to this wish that ISER has published this report. Thanks go to ISER’s publication officer, Nova de Villiers, for undertaking to edit Charlotte’s thesis for this publication. Anjanette Haller assisted with typing. Readers will appreciate their handiwork. This report is dedicated to the youth of Grahamstown. It is hoped it will revitalise their enthusiasm for personal development, and shape fresh ideas and action to make Grahamstown a better place to grow up in. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

A case study of multigrade teaching in Canada: implications for South Africa

- Description: This study examines multigrade teaching in selected schools in Canada and its implications for improving multigrade teaching in South Africa, where over 50 % of primary schools are multigrade and the teachers have not received preparation in multigrade teaching. The case study method was adopted because it allowed for 'an intensive, holistic description and analysis' of the multigrade classroom. The approach is interpretivist, based on the assumption that social phenomena are 'socially constituted' and 'valuationally based'. Research techniques included a literature review, interviews and observations. Four classrooms with grade combinations ranging from two grades to eight grades (Kindergarten to grade 7) were studied. Despite problems such as the lack of official recognition, inadequate teacher education and support - problems common to both Canada and South Africa - the Canadian teachers managed their classrooms effectively. This was indicated by their understanding of the children's needs, their integration of the curriculum for teaching across the grades and the learning areas, their use of effective instructional strategies and their involyement of parents in the classroom. A reason for their success may be that their teacher education includes child-centred, activity based approaches, integration of the curriculum, critical thinking, flexibility and effective instructional strategies, which they may adapt for effective multigrade teaching. The study found that successful multigrade teaching depended on the teacher. For South Africa, this may imply that intervention programmes should focus on relevant preparation and support for multigrade teachers. The emphasis on material resources in the implementation of Curriculum 2005 has not been balanced with adequate training on policy, curriculum and instructional strategies. Teacher education should include methodologies that are experiential, reflective and participatory. A variety of instructional strategies should be employed in the multigrade classroom. The respondents in the study believed further that multigrade teaching is more beneficial than single-grade teaching because it caters for the diversity of needs amongst children and allows for peer tutoring, thereby exploiting Vygotsky's theory of the 'zone of proximal development'. Thus, instead of viewing multigrade teaching as a temporary phenomenon, it should be viewed as an opportunity for improving school effectiveness.

- Description: A cognitive behavioural treatment program for chronic lower back pain was designed, implemented and evaluated. The outpatient treatment program included education sessions, goal setting, graded activity training, physical exercise, relaxation training, cognitive techniques, social skills training, and medication reduction. Three participants volunteered to participate in the eightweek treatment program. Of the three participants, only one completed the program successfully. The results were used to critically discuss and evaluate the literature. The successful participant showed significant improvement in activity levels, decrease in subjective levels of pain, as well as decreased levels of anxiety and depression. It was shown that correcting cognitive distortions (e.g. selective abstraction, catastrophising, misattribution) and challenging early maladaptive schemas of abandonment, emotional deprivation and emotional inhibition (Young, 1990) assisted in enhancing coping mechanisms and the belief that the pain episodes would be short-lived and could be controlled. There was considerable improvement for the second participant, although he chose to withdraw from the program prior to its completion. The components of the psycho-education, relaxation and stress management and exercise program were beneficial for him. The third participant failed to accept the treatment formulation, and did not engage collaboratively in the treatment program. The case is presented as a point for examining therapeutic ailures.

- Description: The aim of establishing the Transkei Teachers’ In- Service College (Trinset) in 1986 by the former Transkei Department of Education, was to alleviate the problem of inappropriately qualified teachers. This problem was seen as impacting negatively on the performance of matriculation candidates in the final examinations. In the twelve years since the college’s inception there has been no formal evaluation, this despite the perception of the importance of evaluation as an integral part of planning and implementation for any educational endeavour (Mc Naught, Taylor & O’Donoghue, 1990). This study analyses the courses offered at Trinset with particular reference to the subject of Geography. The aim is to explore how best these courses can support educators in the light of the current changes in South African education. The analysis of the in-service courses used a multifaceted approach guided by the participatory principle underlying Fourth Generation Evaluation. The analysis of the in-service courses offered by Trinset, in particular by the Geography Department, has served to raise questions and to highlight issues that are seen as particularly valuable in the reconfiguration of Trinset that is part of the current educational transformation process in South Africa in terms of the provision of in-service education.

- Description: Many schools in South Africa suffer from the consequences of bad leadership and management practices. A contributing factor to this problem is the inadequate preparation of school leaders for the wide variety of challenges facing them. This study formed part of a three-year project to develop a preparation programme for school leaders in the Southern Cape area of South Africa. Its aims focussed on the identification of principles for the design of preparation programmes leading to improvements in practice. Twelve teachers and principals participated in the project. They enrolled for a programme in school leadership designed and offered by the University of Port Elizabeth in consultation and cooperation with the Southern Cape Learning Resource Unit in George. Five sources were utilized for the provision of data: - The existing literature on the development of preparation programmes; - The group of twelve participants of the programme; - The four school principals in the group who acted as a focus group; - The staff and certain documents from the schools where these four principals are employed; - Local stakeholders with an interest in the success of the programme. Research methods typical of the interpretive tradition were utilized in orderto arrive at a better understanding of the needs of participants and of those elements of programmes which have the greatest impact on practice. Among the insights to have emerged from the study are the following: - The fact that the preparation of school leaders is a complex and multifaceted process which is enhanced by variety, continuous interaction between presenters and participants, flexibilityt o respond to changing needs and contexts, and an ongoing implementation in and feedback from practice ; - The central role played in the professional and academic growth of participants by individuals and groups around them; - The importance of action research as a tool in the accomplishment of a variety of goals in the preparation of school leaders. The main contributions of this study include: - A framework for the development of preparation programmes, ensuring the inclusion of a wide range of elements enhancing the effectiveness of the course; - A framework for the establishment of professional networks supporting participants in preparation programmes.

- Description: South Africa is living is turbulent times at present. Non-government educational organisations are challenged by changes in education policy and by scarcity of donor funding for their work. This study focuses on the management of organisation change in a non-government organisation (NGO) working in rural areas of the Eastern Cape Province. I undertook the research to gain a clearer understanding of the management of organisational change. I used a third-wave change management approach, the future search conference, to conduct the process of change with the NGO. It focuses on the positive aspects of the organisation, its potential and its desired future. I conducted both the study and the future search conference as participatory action research, which involved the participants in the cycles of planning, action, observation and reflection and thus built ownership of the solutions they generated. I used the accounts of the activities arising from the future search conference, minutes of meetings, semistructured interviews and observation of behaviour to gather data. I analysed the data using triangulation, and in particular, space triangulation, to minimise the impact of the differences in culture and language use in the facilitator and participants. Analysis of the data collected revealed in the NGO that change and transformation are slow processes requiring ongoing support from the OD consultant. The staff defined organisational effectiveness, the goal of organisational change initiatives, in terms of fundraising ability. This ability embraces many of the qualities of a learning organisation and open systems thinking, two requirements for successful organisational change. In the NGO both organisation development and transformation were processes as well as products, and changes could not easily be measured until after the processes were completed. Organisational culture, and in particular the juxtaposition of the values of the organisation and staff and those of its partners and clients, played an important role in transformation. The differences lay in a ‘being’ and a ‘task’ orientation and the staff’s responsibility lay in building connections between the two. The staff received the approach of the future search conference well and there was an equally good fit between the future search conference and participatory action research. This needs to be investigated further with regard to change management in South African organisations.

- Description: This thesis investigates the policing activities of the South African Police (SAP) in Port Elizabeth from the formation of the SAP in 1913 to the creation of two separate police districts in the city in 1956. It begins with the recruitment and training of police personnel, outlining the difficulty in obtaining sufficient white recruits for most of the period while at the same time stressing the ease with which the Force was able to obtain black recruits. The preponderance of Afrikaner policemen serving in Port Elizabeth from the 1920s onwards is made clear, as is the para-military nature of the SAP, which was maintained and reinforced as a result of training methods and the process of socialisation. As state servants, police personnel were expected to serve loyally and obediently a state becoming increasingly repressive towards its black citizens. Generally inadequate conditions of service remained the norm throughout the period yet the SAP’s commitment to the state never wavered, bar one isolated, short-lived incidence. The administration and functioning of policing in Port Elizabeth is explored by focussing on specific organisational features pertinent to the city and the changes wrought by the police hierarchy to deal with the city’s demographic and spatial expansion.

- Description: This thesis investigates the policing activities of the South African Police (SAP) in Port Elizabeth from the formation of the SAP in 1913 to the creation of two separate police districts in the city in 1956. It begins with the recruitment and training of police personnel, outlining the difficulty in obtaining sufficient white recruits for most of the period while at the same time stressing the ease with which the Force was able to obtain black recruits. The preponderance of Afrikaner policemen serving in Port Elizabeth from the 1920s onwards is made clear, as is the para-military nature of the SAP, which was maintained and reinforced as a result of training methods and the process of socialisation. As state servants, police personnel were expected to serve loyally and obediently a state becoming increasingly repressive towards its black citizens. Generally inadequate conditions of service remained the norm throughout the period yet the SAP’s commitment to the state never wavered, bar one isolated, short-lived incidence. The administration and functioning of policing in Port Elizabeth is explored by focussing on specific organisational features pertinent to the city and the changes wrought by the police hierarchy to deal with the city’s demographic and spatial expansion. The SAP tended to employ three different forms of policing in the city as a result of its apartheid-driven agenda which compelled it to differentiate between the various population groups in terms of maintaining law and order. The privileged white community experienced routine, civil policing whereas the black community was policed largely in a socially and politically oppressive manner; this was in line with government policy.

- Description: Media coverage of the poor state of this country's education system has described public images of the teaching profession which provide a context for the research described in this paper. The research is concerned with how and to what extent work identity is reflected in the life stories of five female teachers from a rural village in the Eastern Cape. A social constructionist approach is taken to the meaning and construction of identity, and the paper describes the process of a narrative method of analyzing and interpreting the stories. An initial analysis reveals that the participants had few career options and little choice of career. Further analysis is concerned with interpreting how the teachers create coherence in their stories around this lack of choice as well as within the larger social and historical context. Simultaneously there is an interpretation of the participants' work identity. The teachers create coherence in their narratives around their families and their socioeconomic or cultural circumstances, but make no explicit reference to the political context of their work choices, which were made in the context of the restraints of the Apartheid era. From each teacher's story an understanding of their unique work identity emerges. These alternative understandings provide a contrast to the images constructed by the media.

- Description: With the disappearance of the superpower conflict that characterised the Cold War era, many observers have begun to question whether the Non-Aligned Movement (NAM) has a role to play in the post Cold War era. However the emergence of a number of issues on the international agenda, such as United Nations peacekeeping operations, global environmental issues and an increasing unwillingness on the part of the major economic powers to abide by GATT/WTO rules, have increasingly become of concern to non-aligned states. However whilst the United States has recognised that these issues require leadership in dealing with them, it has not been willing to supply that leadership. It shall therefore be argued that the changing nature of hegemony in world politics has set conditions that allow non-aligned middle powers and institutions greater scope for action and influence. The emergence of these issues has provided a scope for non-aligned middle powers, acting in accordance with their interests to play alternate leadership roles within an expanded scope for institutions, such as organisations, regimes and multilateralism, in addressing the interests of non-aligned states. Firstly in looking at an expanded role for organisations, the United States has increasingly been unwilling to play a leadership role within UN peacekeeping operations. The continuing importance of the neutrality of UN peacekeeping operations has provided a scope for nonaligned middle powers to play a burden-sharing role with the great powers in addressing the concerns of non-aligned states with regard to these operations. Secondly in looking at an expanded scope for regimes, the emergence of a regime in the issue of ozone depletion may provide a foundation to analyse how non-aligned middle powers may play a bridge-building role between North and South in the issue of climate change. Middle powers could therefore play this role in the absence of United States leadership within this issue. Thirdly, the role of the Cairns Group within the Uruguay Round in addressing non-aligned states’ interests of maintaining stable agricultural trade, can be seen as a model of small group multilateralism in bridging the divide between the major powers in issue specific areas.

Such variation is observed in different cohorts and populations, and explains why several names have been applied to the same species. Larvae of P. glaucum also have considerable ecological tolerance, accounting for the abundance and widespread distribution of the species in the Afrotropical Region. New records from Kenya, Lesotho, Namibia and Zimbabwe are provided.

- Description: One problem of intensive fish culture systems is the progressive build-up of toxic wastes such as ammonia. The possibility of improving aquaculture water quality using two kinds of zeolite is discussed. Zeolites are alumino-silicates whose framework allows them to exchange cations. Ion exchange has been demonstrated to be competitive with other methods of ammonia removal due to the high selectivity for ammonia exhibited by zeolite materials. In this study an unknown Zambian zeolite (identified as laumontite by X-ray diffraction techniques) and Pratley clinoptilolite (a South African zeolite) were tested under laboratory conditions and in a fresh water recirculating system. Ammonia cation exchange capacities (CEC) and suitable application rates for efficient water treatment were determined using the batch and column ion exchange procedures. Estimated ammonia uptake, the most important criterion used to assess performance of zeolite filters was strongly influenced by zeolite type, particle size, pre-treatment, regeneration and ion exchange method used. Statistical analysis showed significant differences in average ammonia CEC values between clinoptilolite (14.94 mg g⁻¹) and laumontite (2.77 mg g⁻¹), with the former displaying a higher Na⁺ ® NH₄⁺ exchange rate especially in the early reaction stages. This difference accords with the higher purity of clinoptilolite, 47% as opposed to 4.7% for laumontite, which makes it a better zeolite for ammonium removal. CEC increased linearly as particle size of the clinoptilolite was reduced resulting in a linear regression model (y = 18.29 – 3.704 x; r² = 74%). Pre-treatment of clinoptilolite using 1N NaCl significantly improved the ammonia CEC of clinoptilolite. Overall performance of both the batch and column methods achieved after regeneration (18.3 mg g⁻¹) was 25% higher than the estimated CEC values (13.0 mg g⁻¹) for the unregenerated samples of clinoptilolite. Comparison of CEC estimates using Pratley clinoptilolite, showed that average batch CEC estimates were significantly lower than the column method estimates. The average ammonia CEC values estimated in a fresh water recirculating system (5.80 mg g⁻¹ and 4.12 mg g⁻¹ for the 0.7-1.0 and 1.0-1.4 mm particle sizes, respectively) were significantly lower than the column and batch estimates for the same particle sizes (P < 0.05). Some nitrite (NO₂) and nitrate (NO3) build up was experienced probably due to the growth of autotrophs in the filters. Mass balance of nitrogen (N) for the three treatments of the fish trial (0.7-1.0 mm, 1.0-1.4 mm and the control treatment that had no zeolite in the filter) indicated that less that 10% of the N was retained for growth. It was found that 60% of the NH₄-N present associated with the soluble N was available for absorption by the zeolite filter or biological nitrification and that a total of approximately 22% of NH₄-N available was absorbed by clinoptilolite. The results indicate that the rate of nitrification can be deductively estimated by allowing a zeolite filter to become a biological filter. It is concluded that water treatment by ion exchange using natural zeolites, provides a reliable and efficient method for ammonia removal and appears to be a viable supplementary water treatment method for fresh water systems.

- Description: This thesis analyses the law of child maintenance in South Africa with particular reference to the effects of marriage, death and divorce on such an obligation. In the introductory section, the types of South African family are demographically and statistically sketched, from a socio-legal perspective with some reliance on interdisciplinary research to assess the prevalence of the AID/HIV epidemic in South Africa, and the effects of poverty and ageing on the incidence of marriage and death. In the second part of the thesis, the parental child maintenance obligation is analysed in the common law context. The effects of serial marriage and arificial conception are also analysed with regard to their effect on the concept of biological parent. The nature and definition of parenthood is examined and the diverse and fluid nature of parenthood in South African society is stressed, particularly in relation to children's welfare. One of the aims of the thesis is to indicate how parenthood refers to a fluid set of social practices which are both biologically and culturally situated and thus have a complex effect on the maintenance obligation. The procedural problems of enforcement are also analysed in the light of recent amendments to the law in terms of the Maintenance Act 99 of 1998 (not yet in force) and some further proposals for reform in this area are proposed. The third part of the thesis examines the state obligation to maintain children, especially in the light of the state's commitments to children in terms of the Constitution of the Republic of South Africa Act (l08 of 1996) and its international commitments in terms of the United Nations Convention on the Rights of the Child which was ratified by the South African government on 16 June 1995. In the fourth part of the thesis, there is some comparative analysis, firstly, of the procedural law reforms proposed in Namibia as a result of detailed research done there. Secondly, alternative methods of assessing and enforcing child maintenance obligations in Australia and England are examined and briefly assessed in relation to their possible implementation and efficacy in a South African context. Finally, the thesis concludes with an overall synopsis of the position in this country and some proposals for reform in the light of the international and constitutional commitments of the state.

In the introductory section, the types of South African family are demographically and statistically sketched, from a socio-legal perspective with some reliance on interdisciplinary research to assess the prevalence of the AID/HIV epidemic in South Africa, and the effects of poverty and ageing on the incidence of marriage and death. In the second part of the thesis, the parental child maintenance obligation is analysed in the common law context. The effects of serial marriage and arificial conception are also analysed with regard to their effect on the concept of biological parent. The nature and definition of parenthood is examined and the diverse and fluid nature of parenthood in South African society is stressed, particularly in relation to children's welfare. One of the aims of the thesis is to indicate how parenthood refers to a fluid set of social practices which are both biologically and culturally situated and thus have a complex effect on the maintenance obligation. The procedural problems of enforcement are also analysed in the light of recent amendments to the law in terms of the Maintenance Act 99 of 1998 (not yet in force) and some further proposals for reform in this area are proposed. The third part of the thesis examines the state obligation to maintain children, especially in the light of the state's commitments to children in terms of the Constitution of the Republic of South Africa Act (l08 of 1996) and its international commitments in terms of the United Nations Convention on the Rights of the Child which was ratified by the South African government on 16 June 1995. In the fourth part of the thesis, there is some comparative analysis, firstly, of the procedural law reforms proposed in Namibia as a result of detailed research done there. Secondly, alternative methods of assessing and enforcing child maintenance obligations in Australia and England are examined and briefly assessed in relation to their possible implementation and efficacy in a South African context. Finally, the thesis concludes with an overall synopsis of the position in this country and some proposals for reform in the light of the international and constitutional commitments of the state.

- Description: An annotated checklist of the species of the fish families Labridae and Scaridae is presented; 541 valid species are recognized, including 68 genera and 453 species of labrids and 10 genera and 88 species of scarids. Thirty undescribed species of wrasses and two undescribed parrotfish species are also included. A list of nominal species is given, with their present assignments; nominal species of uncertain status are placed as incertae sedis and listed separately. A list of nomina nuda is also provided. The valid genera and species are listed alphabetically, with their synonyms and distributions. Examination of the original descriptions and type material (when extant) of previously unplaced nominal species of labroid fishes led to identification of 69 new synonyms. The generic names Artisia de Beaufort, 1939 and Emmeekia Jordan & Evermann, 1896 are here recognized as new synonyms of Halichoeres Ruppell, 1835. For the Labridae, 65 new synonyms of valid species are listed. Labrus psittaculus Richardson, 1840, a valid species of Pseudolabrus, is a primary homonym of Labrus psittaculus Lacepede, 1801; the next available name for this species is Labrichthys rubicunda Macleay, 1881 and the new combination Pseudolabrus rubicundus is proposed. The following new combinations are included: Pseudojulis inornatus Gilbert, 1890 is a valid species of Pseudojuloides; Xyrichtys perlas Wellington et al., 1994 is a valid species of Novaculichthys. For Scaridae, Sparus abildgaardi Bloch, 1791 is a senior synonym of Sparisoma chrysopterum (Bloch & Schneider, 1801), but a request of the International Commission has been made to reject abildgaardi in order to conserve S. chrysopterum; and Scarus visayanus Herre, 1933 is a new synonym of Scarus tricolor Bleeker, 1847. Pseudoscarus microcheilos Bleeker, 1861 is a synonym of Chlorurus strongylocephalus (Bleeker, 1854). , Rhodes University Libraries (Digitisation)

- Description: This research will appraise the production and utility of digital atlases in an African context, using personal experience gained through the production of a digital atlas for Swaziland, the opinions obtained from other producers of African digital atlases and relevant literature. Since the 1950s, decision makers and researchers have viewed information as a powerful contributor to national development. Over the past thirty years, developed countries have increased the efficient collation and dissemination of geographic information through the utilization of the digital environment. The development of Geographic Information Systems (GIS) has increased the range of applications attainable in digital mapping projects. Applications have ranged from resource inventories to the monitoring of environmental degradation, crime patterns and service provision. The patchy history of data collection, analysis and mapping in Africa, has had a limiting effect on the ability of countries to identify, plan and control their resources efficiently. Despite the desire to automate the mapping process and reap some of the planning benefits evident in the developed world, Africa has not succeeded in mobilising full technological potential. Political instability, poor infrastructure, the absence of national policy guidelines, and a lack of skilled manpower are some of the issues which have limited utilization. Despite many of the hurdles faced by African countries, automated mapping and analysis technologies are still being pursued. The role of computers in the utilisation of data has become apparent through several means, one of which is the digital atlas. Analytical functions in many of these products allow situation modelling and provide superior graphic displays in comparison to their paper counterparts. Several African countries have embarked on the development of national digital databases and in some cases have produced digital national atlases. The potential to improve resource utilization, service provision and land use planning using these atlases, does exist. The production and utility of these atlases in an African context, however, needs closer assessment. "Computers don't clothe, don't cure, don't feed. Their power begins and ends with information. Their usefulness is therefore strictly linked to the ffectiveness of the information" (Gardner,1993:16).
