- Description: The spotted grunter (Pomadasys commersonnii) is an important, estuarine-dependent, fishery species in southern Africa. Since estuaries are essential habitats in the life history of this species, the quantification of area use patterns and movements is important for fisheries management. In this study, acoustic telemetry was used to investigate movements, use of habitat and home range dynamics of spotted grunter in the small intermittently open East Kleinemonde Estuary on the Eastern Cape coast of South Africa. Nine spotted grunter (range: 326-489mm TL) were surgically equipped with uniquely coded acoustic transmitters. Positional fixes were obtained by manual tracking tagged individuals on six days and six nights during five tracking sessions from March to November 2004. In addition, five stationary data-logging receivers, moored at specific locations from the mouth to the top of the estuary provided additional long-term monitoring. Kernel home ranges (95% UD) varied in size (26 296-165 321m²) but were all located in a common high use area situated between 300-1 300m from the estuary mouth, which coincided with the highest abundance of prey items. There was no significant variation in home range size [C² (N = 9, df = 4) = 4.18; p = 0.38] between the temporally segregated tracking sessions (over nine months). The persistence of these home range estimates were confirmed by the long-term data-logging receivers. There was no significant diel variation in home range size [F(4, 64) = 0.05, p = 0.99] or core area size [F(4, 64) = 1.40, p = 0.25]. Fish length showed negative, although not significant, relationships between home range size (p = 0.225); number of home range areas (p = 0.065); core area size (p = 0.512) and home range length (p = 0.320). Use of habitat and home range dynamics of spotted grunter in the East Kleinemonde Estuary were consistent over the nine month study period, and they appeared to be influenced more by biotic than abiotic factors. However, when the mouth opened at the end of the study, most tagged fish vacated their home ranges and emigrated to sea.

- Description: This study investigates short stories published in South Africa and in Zimbabwe before the turn of the twenty-first century. The short story as a genre provides a more accessible and shorter means of viewing literary trends after the official end of the hostilities of apartheid and colonialism. Because of their brevity and specific focus, these short stories from many voices allow a glimpse of different arenas affecting contemporary reality. Post-independence stories reveal that in the process of navigating or directing hope after independence, people are sometimes left bereft as disenchantment with politics sets in, leaving people to search for hope in areas of their everyday lives such as marriage, birth and friendship. But because their lives are also fraught with conflict, hate and betrayal, hope may remain uncertain and prospects frightening. Chapter One embarks on a brief historical and political background of South Africa and Zimbabwe. This chapter also conceptualizes the issues of hope and disillusionment in the South African and Zimbabwean socio-historical contexts. Chapters Two and Three analyze selected stories from South Africa and Zimbabwe, respectively, focusing on issues with which the writers are preoccupied, especially how they explore hope and disillusionment. The analyses of the stories in these two chapters are structured chronologically depicting events in the stories. Thus the study creates its own narrative of South African and Zimbabwean life towards the new millennium. These two chapters discuss how meanings, significances and ramifications of the post-colonial community are negotiated and re-negotiated in selected stories, highlighting the challenges and engagements with hope and disillusionment dramatized in short prose fiction. Chapter Four will undertake to conclude with comparisons of the selected stories, discussing the implications of the study for South African and Zimbabwean contemporary societies at the turn of the twenty-first century. Granted, it is always difficult to generalize about a society from such highly individual, personal stories. But my study suggests that at the turn of the twenty-first century in South Africa, disillusionment is beginning to displace the heady expectation many felt at the 1994 election. And perhaps even more unlikely, given the current crisis, Zimbabwean stories from recent years show people hopefully waiting for the new millennium, a dawning of new, unpredictable possibilities.

- Description: Trees within the homestead area provide many functions to rural households. However, within the semi-arid regions of southern Africa, there has been only limited examination of the correlates between the socio-economic attributes of rural households and the density, species richness and types of trees they keep. This paper reports on a multivariate analysis of household attributes in relation to homestead tree holdings from six rural villages in South Africa. In terms of density of trees per household, gender of the household head was the only significant correlate, with female-headed households having significantly fewer trees than their male-headed counterparts. This was especially so for the density of indigenous trees.

- Description: This thesis presents a value-laden understanding of development that acknowledges that development is human centered. The study re-emphasizes that human development which has become a powerful element of current development discourse is not just a social, economic and technological challenge; it is also an institutional and political challenge. The study therefore analyzes the notion of human development with the intention of improving it by placing more emphasis on the aspect of politics and human agency (the ability to act and be an agent of one‘s life). Politics here is understood beyond its usual institutional focus or identification with government, politicians and parliaments to include a much wider and much more important and dynamic range of activities found in all human groups such as institutions and societies. The study then demonstrates that since development is a process, individuals need to work collectively towards a common good so as to realize their development potential. This means creating a confederation of development where governments, citizens and non-governmental organizations work in partnership guided by a culture of collectiveness (civic culture) in order to produce more empowered citizens. The major argument in this study is the concern for citizens to effectively participate in areas that affect and impact on their lives and consequently be in a position to hold accountable institutions that affect their decision making capabilities. Hence human agency in this study signifies and can be justified as an important aspect of the process of participation leading to empowerment. , Thesis (PhD) -- Faculty of Management and Commerce, 2008

These two biological treatment processes are each characterised by groups of micro-organisms and their associated enzymes. Hydrolytic enzymes secreted by these micro-organisms are vital for the rate-limiting step of hydrolysis in the treatment of highly polymeric substrates present in sewage sludge. In this mini-review, the effects of mass transfer limitation, metabolic intermediates, extracellular polymeric substances (EPS), electron acceptor conditions and pH and temperature on the activity of these enzymes are summarised. The most salient and current perspectives of the significance and the role that hydrolytic enzymes play in sewage sludge treatment are highlighted.

- Description: In this thesis mass spectral and chromatographic techniques were developed and applied to identify and characterise numerous novel platinum(II) and (IV) compounds designed as anticancer agents. In a novel method for the synthesis of cis-oxalato(trans- -1,2- cyclohexanediamine)platinum(II) or oxaliplatin these techniques could be applied to differentiate between the molecular complex and the autoionised analogue (viz. Ptdach2 2+Ptox2 2-). In another novel synthetic method for the same compound the ligand exchange reactions at various temperatures could be investigated and kinetic curves obtained served to illuminate the chemistry involved, indicating the role of small amounts of water in the essentially non-aqueous solvent systems dmf and isoamyl alcohol respectively. These allowed ligand exchange without resulting in hydrolyses even up to 85°C. The ionisation rate of divalent platinum halide complexes was determined for various amine ligands as well as N-S chelate ligands. A comparison of these could suggest why N-S complexes have poor anticancer action. Ionisation was not only studied for neutral molecular species but also for monocationic ones. Relationships could be found with stereochemical aspects of the chelates used. By investigating results of EV-CAD studies thermodynamic data could be obtained which indicated that bond strength decreases from chloro to iodo analogues although extent of ionisation in aqueous solution, i.e kinetic stability, is the reverse. Products formed by the reaction of NO2 gas with Platinum(II) compounds could be identified and separated which greatly contributed to the understanding of the chemistry involved in the formation of mononitro platinum(IV) complexes. Some of these proved to have exceptional anticancer properties. Studies of the interaction of thiol containing biomolecules were performed as a function of time. The results contributed to the understanding of the action of the anticancer agents.

- Description: To the Editor: The use of maggots to clean necrotic wounds, known as maggot debridement therapy (MDT), has long been known to the scientific world. Its use has been recorded since the 1500s when soldiers’ wounds were often infested with maggots. Napoleon’s surgeon, Baron Dominic Larrey, reported that wounds that were infested with maggots appeared to heal faster than those without maggots.1 William Baer is considered to be the founder of modern MDT. While treating soldiers in World War I, he noted the good condition of wounds that had been infested with maggots, and was the first doctor on record to experiment with the use of maggots in treating infections.1 MDT even featured in the recent version of the film ‘Spartacus’. Various species of flies have been used for MDT,1 the most commonly used being Lucilia sericata, a greenbottle blowfly (Figs 1 and 2). This fly is closely related to another greenbottle, L. cuprina, but L. cuprina feeds on live as well as necrotic tissue, which is undesirable in MDT. L. cuprina is commonly named the ‘sheep blowfly’ because it is responsible for fly-strike in sheep, a form of massive, usually rectal myiasis that can kill sheep. A recent article2 suggested that L. cuprina was being used successfully for MDT at the Eugene Marais Hospital Wound Care Centre (EMHWCC). As this would be inconsistent with international experience in MDT and at odds with the usual biology of L. cuprina, it was decided to check the identity of these flies.

- Description: The local governance system has undergone positive changes since 1994 when the Government of National Unity took over power in Rwanda. The government has instituted democratic changes in the structure and functioning of local government through decentralisation. Since 2000 when the decentralisation policy was launched, Rwanda has evolved a model of local governance that has come to be emulated by its neighbouring countries. Since 2000, when the Local Government Act affected the decentralised structures of local government, some changes have occurred, challenges have emerged and constraints have been experienced in the implementation of the policy of decentralisation. Methodology used in the impact assessment study The researcher administered questionnaires, conducted interviews and documentary analysis. The assessment covered (3) three districts which were purposively selected on the basis of criteria that were considered sufficiently representative and based on the rationale of the study. Key findings of the study The study established that the restructuring exercise streamlined the structures of local governments, aligned mandates to the structures, and graded jobs in line with responsibilities. These reforms have improved the performance of the local governments. Despite notable improvements, the study established that there were still gaps in the local government system that needed to be addressed. These included: i. There is a big skills gap in most local governments. Some positions in local government are not filled due to inadequate resources. ii. Some local governments are finding it difficult to attract qualified and competent personnel to take up jobs at technical and managerial levels. iii. Local government lack attractive working environments. iv. There are limited career growth opportunities in local government service. xiv v. There is low local revenue. This has imposed limitations to accountability, supervision and monitoring of local government programmes. vi. Professional staff in local government is not adequately facilitated to do their work efficiently and effectively. vii. The existing capacity building programmes contribute marginally to career growth of individual staff members. viii. New reform programmes for improving service delivery such as results oriented management (ROM) and fiscal decentralisation strategy (FDS) have been rolled out but are not yet utilised in some of the local governments.

Impediments to the delivery of socioeconomic rights in South Africa

- Description: [from the Introduction] The purpose of including Second and Third Generation (STG) rights in a constitution is to provide guidelines to lawmakers to formulate policy and to enable the courts to intervene where these policies are not being implemented satisfactorily. In theory these rights allow citizens to demand from the state access to basic needs, such as adequate land, housing, education, health care, nutrition, and social security. However, this inclusion of rights in the constitution often does not translate into action. The first reason for this is that Second and Third Generation rights may clash with First Generation rights. For example the right to private property may, and in South Africa does, contradict the need for land for the majority. The major problem is whether the policies flowing out of Second and Third Generation rights are pursued with enough vigour by governments, the private sector, primary groups and individuals to overcome this contradiction. In many countries in the world it is the poorest sections of the population, and as Mamdani (1996) pointed out, migrant non-citizens, that bear the brunt of administrative and bureaucratic bungling and neglect.

- Description: This is an exploratory study on the implementation of the Domestic Violence Act No 116 of 1998 in South Africa. It is a case study of two townships in the Nkonkobe Municipality District, Eastern Cape Province. The study was conducted at Ntselamanzi and Upper Qhumashe townships in Nkonkobe Municipality District, Eastern Cape. Since this is a qualitative exploratory study, in-depth interviews were conducted on a sample of ten women in abusive relationships and focus group interviews were conducted on five service providers for a triangulation. A study of related literature focused on African women in battered relationships. An African women’s perspective on the experiences of abuse have been explored. Gender based radical feminist views were discussed and legislations and conventions were analyzed from a human rights perspective. The implementation of the Domestic Violence Act and the role of service providers were also looked into. The findings suggest that African women experience abuse in partner relationships. They sustain grievous bodily harm, psychological, emotional and financial abuse. The patriarchy system, alcohol abuse, infidelity, traditional practices and failure to maintain children have been cited as some of the reasons. The social networks and service providers assisted these women to some extent. However, there is need for ethnic sensitive interdisciplinary training approach on African communities on the Act and a legal system that is accessible to rural women in order to curb further abuse. Various recommendations have been put forward. The study indicated a need for ethnic sensitive empowerment programs for the abused, rehabilitative programs that take into cognizance human rights violations of these women and the abusers, and effective legal remedies to prohibit women abuse.

- Description: The development of electronic commerce (e-commerce) is the most visible business use of the World Wide Web. The primary goal of an e-commerce site is to sell goods and services online. This project deals with developing an e-commerce platform for marginalized communities of the Eastern Cape region, South Africa. An online “shopping mall” to support the marketing of art and crafts from disadvantaged communities is presented, with Linux-Apache-MySQL-PHP (LAMP) as the development environment. Free and Open Source Software has been chosen to develop the virtual shopping mall system because the use of Open Source allows easy localization and extensions to the system developed and long term sustainability, as the source code is available. Also, it might start a “virtuous” circle, whereby young members of the communities hosting art and craft makers become involved in maintenance, and then production, of software systems. One important design constraint from the e-commerce platform presented in this thesis is the possibility for the art and craft makers to manage their shops directly, from the initial loading of their wares to the day-to-day maintenance, such as changes of price or items. The user requirement elicitation and initial field testing were conducted in Dwesa, an area on the wild coast, South Africa. The system currently comprising two shops is live at the time of writing this thesis at www.dwesa.com.

- Description: In fisheries, advice for the management of fish populations is based upon management quantities that are estimated by stock assessment models. Fisheries stock assessment is a process in which data collected from a fish population are used to generate a model which enables the effects of fishing on a stock to be quantified. This study determined the effects of various data sources, assumptions, error scenarios and sample sizes on the accuracy with which the age-structured production model and the Schaefer model (assessment models) were able to estimate key management quantities for a fish resource similar to the Cape hakes (Merluccius capensis and M. paradoxus). An age-structured production model was used as the operating model to simulate hypothetical fish resource population dynamics for which management quantities could be determined by the assessment models. Different stocks were simulated with various harvest rate histories. These harvest rates produced Downhill trip data, where harvest rates increase over time until the resource is close to collapse, and Good contrast data, where the harvest rate increases over time until the resource is at less than half of it’s exploitable biomass, and then it decreases allowing the resource to rebuild. The accuracy of the assessment models were determined when data were drawn from the operating model with various combinations of error. The age-structured production model was more accurate at estimating maximum sustainable yield, maximum sustainable yield level and the maximum sustainable yield ratio. The Schaefer model gave more accurate estimates of Depletion and Total Allowable Catch. While the assessment models were able to estimate management quantities using Downhill trip data, the estimates improved significantly when the models were tuned with Good contrast data. When autocorrelation in the spawner-recruit curve was not accounted for by the deterministic assessment model, inaccuracy in parameter estimates were high. The assessment model management quantities were not greatly affected by multinomial ageing error in the catch-at-age matrices at a sample size of 5000 otoliths. Assessment model estimates were closer to their true values when log-normal error were assumed in the catch-at-age matrix, even when the true underlying error were multinomial. However, the multinomial had smaller coefficients of variation at all sample sizes, between 1000 and 10000, of otoliths aged. It was recommended that the assessment model is chosen based on the management quantity of interest. When the underlying error is multinomial, the weighted log-normal likelihood function should be used in the catch-at-age matrix to obtain accurate parameter estimates. However, the multinomial likelihood should be used to minimise the coefficient of variation. Investigation into correcting for autocorrelation in the stock-recruitment relationship should be carried out, as it had a large effect on the accuracy of management quantities.

- Description: This study is a deliberation on students who advance from high school to a higher education institution, without demonstrating the attributes required on admission. They are granted formal access, despite being underprepared for tertiary studies. One of the qualities that they noticible lack is academic literacy. In the course of this investigation, academics had to relate what their perceptions were of the academic literacy of their students at higher education level. Initially, being literate meant the ability to read and write, but the term literacy has assumed a more varied form. The term multi-literacies is employed now, as there are several forms of literacy. These include, Information Technology, Technology, pictorial and numerical literacies, to name a few. Academic literacy constitutes more than one literacy, namely, operational or functional literacy, cultural literacy and critical literacy. These literacies are elaborated on and the role of language proficiency, together with the inter-relatedness between students' linguistic competence and their cognitive ability are discussed in depth. Alternatives are examined to assess how this problem of the lack of academic literacy can be circumvented and what mechanisms can be put in place in order that students can be assisted in their pursuit of academic literacy.

- Description: This thesis is a narrative account of how I have transformed my learning and teaching strategies for Grade 9 learners, generating my own living theory of teaching within a social context with the aim of enabling my learners to construct their own knowledge. My value-embedded practice is reflected in the values I attach to equality, inclusivity, social justice and basic human rights. These embodied values are also a reflection of my commitment to my Christian values which encompass my entire existence and have become the living standards by which I judge the quality of my research. My classroom-based action research methodology is a living transformational process which heralds a change for a more just practice and the inclusion and recognition of the individual. My findings about my learners’ and my own learning offer new conceptualisations about the capacity of my learners to learn in their own unique ways and according to their own potential. I am claiming that the significance of my research is grounded in my ability to demonstrate how I can unleash the untapped potential of learners failing to attain the desired outcomes. I show them how to learn confidently and successfully within a social context using prior knowledge, scaffolding and motivation as teaching and learning tools. This has potential inspiration for new forms of practice and theory in aiming to improve learners’ potential. A significant feature of my account is how my Christian values have been translated into my critical epistemological standards of judgement, and the development of a living theory of practice that enables me to account for educational influences in my learners’ and my own learning.

In search of a regime of responsibility and accountability for perpetrators of torture with reference to persons with special responsibility for protecting human rights

- Description: orture is a serious violation of human rights and it is strictly prohibited by numerous human rights instruments. The prohibition of torture enshrines one of the most fundamental values of a democratic society. Its prohibition in a national constitution commits the country, and specifically its law enforcement officers, to performing their duties with due regard to the essential dignity of every human being. The irony is that the law enforcement officials and the security agents who are entrusted with the responsibility of maintaining law and order in the society sometimes breach the law which they have sworn to uphold. Most of the perpetrators of acts of torture are usually those in positions of state power. In addition, other persons who wield other forms of authority or influence also perpetrate torture. It is contended that both civil and criminal responsibilities of the perpetrators should be explored by bringing them to justice in order to serve as deterrence to others. Despite being stringently outlawed, torture continues to be practised in many countries in the world. The underlying assumption is that, although the prohibition of torture has become part of customary international law, the practice of torture remains widespread. Torturers and those who order or encourage torturers to ply their trade or acquiesce in their doing so, enjoy virtual impunity from prosecution within their own jurisdictions. In many cases, the majority of the torturers go unpunished because they are, most often than not, agents or officials of the state. Nowadays, there are various international human rights instruments prohibiting torture. Violations of the provisions of these instruments by states or individuals will attract necessary and appropriate sanction. The erring state or individual will be held accountable and if found liable, sanctions as contained in the instruments banning torture will be invoked accordingly. It must be stressed that condemnation of torture is universal and its prohibition forms not only part of customary international law, but has joined that narrow category of crimes so egregious as to demand universal criminal jurisdiction. There is no save haven for perpetrators because the various mechanisms and adjudicating bodies of state parties and the United Nations have competent jurisdictions to right the wrong. Furthermore, it must be stressed that there can be no justification for torture because CAT and other important international human rights instruments assume increasing importance tools which have realistic prospects for eliminating torture.

Torturers and those who order or encourage torturers to ply their trade or acquiesce in their doing so, enjoy virtual impunity from prosecution within their own jurisdictions. In many cases, the majority of the torturers go unpunished because they are, most often than not, agents or officials of the state. Nowadays, there are various international human rights instruments prohibiting torture. Violations of the provisions of these instruments by states or individuals will attract necessary and appropriate sanction. The erring state or individual will be held accountable and if found liable, sanctions as contained in the instruments banning torture will be invoked accordingly. It must be stressed that condemnation of torture is universal and its prohibition forms not only part of customary international law, but has joined that narrow category of crimes so egregious as to demand universal criminal jurisdiction. There is no save haven for perpetrators because the various mechanisms and adjudicating bodies of state parties and the United Nations have competent jurisdictions to right the wrong. Furthermore, it must be stressed that there can be no justification for torture because CAT and other important international human rights instruments assume increasing importance tools which have realistic prospects for eliminating torture.

- Description: From introduction: Institutional loyalty, especially in the case of a university, does not mean being uncritical and denying historical truths. The inauguration of the Stephen Bantu Biko Building is, therefore, a good occasion for “a critical appreciation of where we” as Rhodes University “come from”. Credit is due to the pioneers who 104 years ago created Rhodes; to those who, under difficult and financially trying conditions, steered its subsequent development; to those who oversaw its maturation from a University College under the auspices of the University of South Africa to a fully-fledged University in 1951, and to the subsequent generations that energetically toiled to produce the Rhodes University of today’s enviable reputation.
