Laboratory and field host utilization by established biological control agents of Lantana camara L. in South Africa

- Description: Varieties of Lantana camara (lantana) have been introduced into many countries of the world as ornamental plants and have become invasive weeds in many countries including South Africa. In South Africa, it mostly invades the sub-tropical eastern and northern range. Mechanical and chemical control options are expensive and ineffective. A biocontrol programme was initiated in South Africa in 1961. To date, 22 insect species, and a fungus have been introduced, of these 10, and the fungus have established. Three indigenous lepidopteran species and an exotic generalist pest mealybug are also associated with the weed. The variable success of some of the agents released on L. camara worldwide has been ascribed to a few factors. One important aspect is the large range of varieties encountered in the field. It is therefore essential to be able to predict the possible establishment and impact of agents on many varieties. Laboratory trials on five of the established agents showed clear varietal preferences. In the field, most of the biocontrol agents had limited geographic ranges, linked to altitudinal conditions, as higher populations were recorded at low lying warm summer rainfall areas. A pink and orange flower corolla lobe and throat colour combination and plants with few to medium leaf hairs were most abundant in South Africa. Most of the agent species had individual preferences towards different flower colour combinations, as the agents built up different population levels on varieties in the field, within the suitable geographic region for the insect species. Eight agents preferred smooth leaved varieties, while three preferred hairy leaves, and three had no specific preference to leaf hairiness. Varietal preferences thus did play a significant role in agent populations and accompanied impact achieved in the field. New candidate agents need to be proven specific under quarantine conditions and the results extrapolated to predict specificity in the field, while avoiding potential non-target effects. Many authors have questioned the validity of laboratory host specificity trials. The conventional wisdom is that insects portray a far wider host range in the laboratory than what they would do in the field. In other words, laboratory studies measure the physiological host range of an agent and are conservative and usually don’t reflect the ecological host range of agents in the field. To avoid unnecessary rejections of biocontrol agents, this study has made a retrospective study of the host specificity of agents established in the field. Their laboratory and field host ranges were compared and it was found that virtually all the agents reflect similar or less non-target effects in the field than predicted during multiple choice trials. Of the 14 agents, only one introduced species, Teleonemia scrupulosa, and the indigenous species, Hypena laceratalis and Aristea onychote were able to sustain populations on non-target species in the field in the absence of L. camara. Insect populations on non-target species were much reduced compared to that on L. camara. Furthermore non-target effects were only recorded on plant species closely related to the target weed. The multiple choice trials therefore predict field non-target effects accurately. Predictions of non-target effects of candidate agents can therefore be accurately predicted by laboratory studies, in terms of species likely to be affected and to what extent. One field that need further study though is the impact of non-target effects, especially on Lippia species by L. camara biocontrol agents.

- Description: South Africa is 10 years into its new democratic order. An aspect of the country's political transformation has been an official political commitment to gender trans-formation. While great strides have been made towards greater gender equality at the institutional and legal level of society, the present article suggests that highly unequal power relations between men and women continue to be perpetuated in unexpected ways among those whom we would most expect to be capable of resistance. This paper is about how subtle yet deeply embedded ideologies and practices within heterosexual relationships serve to keep highly educated, apparently empowered and liberated women ‘in their place’, ensuring that they do not fulfil their potential. Traditionally women were socialised into assuming their positions in the home as caregivers and unpaid household labourers. The hope of feminism was that education, economic empowerment and an ideology of ‘can do’ independence would liberate women. However, for many women, it is in the most intimate aspects of their lives—in their sexual relationships with men—that this hope continues to be thwarted.

- Description: South Africa is a multilingual country with 11 official languages. However, English dominates as the language of access and power and although the Language-in- Education Policy (1997) recommends school language policies that will promote additive bilingualism and the use of learners' home languages as languages of learning and teaching, there has been little implementation of these recommendations by schools. This is despite the fact that the majority of learners do not have the necessary English language proficiency to successfully engage with the curriculum and that teachers frequently are obliged to resort to using the learners' home language to mediate understanding. This research investigates the classroom language practices of six Grade 8 science teachers, teaching science through the medium of English where they and their learners share a common home language, Xhosa. Teachers' lessons were videotaped, transcribed and analysed for the opportunities they offered learners for language development and conceptual challenge. The purpose of the research is to better understand the teachers' perceptions and problems and to be able to draw on examples of good practice, to inform teacher training and to develop a coherent bilingual approach for teaching science through the medium of English as an additional language.

- Description: Larvae of Sarcophaga (Liosarcophaga) tibialis Macquart were raised on chicken liver under six different constant temperatures. Maximum survival indicated an optimal developmental temperature of near 20°C, while trends in mortality, larval length and larval mass implied that the thermal window for successful development lay between 15°C and 30°C. Using a recently described method to estimate a simple thermal summation model, it was found that the timing of the end of the feeding phase could be estimated by a developmental zero (D0) of 5.2°C (S.E. = 1.21) and a thermal summation constant (K) of 106.4 d°C (S.E. = 8.31) and of the end of the wandering phase by D0 = 4.1°C (S.E. = 0.39) and K = 126.7 d°C (S.E. = 3.28). Published development times at constant temperatures were compiled for 19 other species of flesh flies, and the developmental constants were calculated for six species for which sufficient data were accumulated.

- Description: Effective change leadership is important to any organisation undergoing fundamental transformation. In particular, the ability of senior public sector leaders to successfully drive strategic change is crucial to meeting the developmental and service delivery challenges faced by the Province of the Eastern Cape in ensuring the effective, efficient and innovative government demanded by all its various stakeholders. The creation on 3 October of a Shared Legal Service situated in the Office of the Premier provided a unique opportunity to examine the leadership of this change initiative in the context of the organisational culture that existed in the provincial public service. This thesis consequently probes the phenomenon of effective change leadership by means of an examination of the understandings of the three change agents involved in driving the transformation of the provision of legal advisory services to the provincial administration and its constituent departments. The picture which emerges from the insights of the participants is one that casts a shadow over the validity of the contemporary theory of transformational leadership. Furthermore, the research conducted has identified the need to view the nature of effective change leadership through a more nuanced, situation-specific lens: one that appreciates the role of relationships and emotions, and that recognises the importance of culture and its impact on the success of organisational transformation. The case study of the Shared Legal Service change initiative provides useful insights into the many and varied challenges faced by public sector leaders in driving strategic transformation in the provincial administration. It offers an example of successful change leadership and demonstrates the need for change agents within the public service to harness more emotionally resonant and relational forms of leadership if they are to soar to new heights in meeting the service delivery expectations of all who look to provincial government to deliver the fruits of democracy.

This is a significant move towards a more social orientation and away from an approach that focused almost exclusively on the technical aspects of WRM. This set of two books asks what a social orientation means in practice. Since the National Water Act became law in 1998, how have WRM practitioners involved people in the process of managing water? What have we learnt so far? And how can we use these lessons to move forward? The content of the books is based on research that looked in some depth at national and local participatory practice in South Africa, and also broadly at international trends. The research was conducted by three WRM practitioners and two researchers in the field of participatory approaches.

Living condition in informal settlements: the case of Imizamo Yethu informal settlement in Cape Town, South Africa

- Description: The study examines the issue of living conditions in informal settlements, using the case study of Imizamo Yethu informal settlement in Cape Town. Affordability, lack of space, job related issues, a relatively small formal housing stock available in many urban centres, and deregulation, in terms of both access to land and finance, forced lower income groups to seek accommodation in informal settlements. Here people are exposed to unhealthy living conditions. The study reveals that living in informal settlements often poses significant health risks. Sanitation, food storage facilities and drinking water quality are often poor, with the result that inhabitants are exposed to a wide range of pathogens and houses may act as breeding grounds for insect vectors. In informal settlements people often live in temporary homes constructed with impermanent, basic materials. These inhabitants frequently have little option but to live on marginal land (flood plains or steep slopes, for example), with the consequence that they are the first to suffer the effects of cyclones and floods. In addition, a combination of overcrowding, the use of open fires and flammable buildings leads to danger from accidental fires, burns and scalding. The post-apartheid South African government has tried a number of housing initiatives to help alleviate the housing problem since 1994 when it came to power. These have included the Botshabelo Accord (1994), the Housing White Paper in 1995, the National Urban and Reconstruction Housing Agency in 1995, the Housing Subsidy Scheme in 1995, the Housing Act No. 107 of 1997 and the Policy on People’s Housing Process (1998). The government set itself a target of delivering one million houses within five years. By all indications the government did not fully comprehend the gravity of the problem in relation to available resources. In 2004, the Department of Housing declared its intention to eradicate informal settlements in South Africa by 2014. This followed the unprecedented housing backlog, proliferation of informal settlements, social exclusion and the inability of municipalities to provide basic infrastructure to urban poor households. However, despite these bold interventions by government, the study demonstrates that the provision of low-cost housing can be viewed as a wicked problem. Wicked problems are described to be “ill-defined, ambiguous, and associated with strong moral, political and professional issues”. The study, therefore, concludes that given the complexities surrounding the provision of low-cost housing in South Africa, the government’s ambitions to resolve housing backlogs by 2014 appear to be a far-fetched dream.

- Description: The study examines the issue of living conditions in informal settlements, using the case study of Imizamo Yethu informal settlement in Cape Town. Affordability, lack of space, job related issues, a relatively small formal housing stock available in many urban centres, and deregulation, in terms of both access to land and finance, forced lower income groups to seek accommodation in informal settlements. Here people are exposed to unhealthy living conditions. The study reveals that living in informal settlements often poses significant health risks. Sanitation, food storage facilities and drinking water quality are often poor, with the result that inhabitants are exposed to a wide range of pathogens and houses may act as breeding grounds for insect vectors. In informal settlements people often live in temporary homes constructed with impermanent, basic materials. These inhabitants frequently have little option but to live on marginal land (flood plains or steep slopes, for example), with the consequence that they are the first to suffer the effects of cyclones and floods.

- Description: The purpose of this study is to look at instilling discipline of learners at schools after corporal punishment was abolished by identifying causes of disciplinary problems, alternatives to corporal punishment, and the attitudes of learners, teachers and parents towards alternatives. Data were collected through questionnaires, interviews and observation. Data were collected from learners, teachers and parents. Two neighbouring schools in the Mthatha District of Education were used. A qualitative research approach was used in the study. Findings reveal and support literature consulted that there is a wide range of causes of disciplinary problems at schools. According to the findings, the outstanding difference between respondents on causes of disciplinary problems was on home background. Learners are not in agreement with literature, teachers and parents who all agree that background is the cause of misbehaving of learners at school. The study reveals that learners, teachers and parents hold different views about alternatives to corporal punishment. While teachers, parents and literature are in agreement on using parental involvement as an alternative to caning, learners do not want parents to be involved. Teachers, the findings reveal, are not in favour of alternatives that need to be supervised by them. The final outcome of this study focuses on positive alternatives to corporal punishment. These include parental involvement, manual work, the application of school rules and enforcement of the code of conduct. Learners would also like to be disciplined and parents are in favour of being involved in the maintenance of discipline in schools.

- Description: This study investigates the popular pleasures produced by readers of men's magazines, focusing primarily on the publication, Men's Health, which represents a new type of magazine catering for men. Using qualitative research methods such as textual analysis and reception analysis, the study explores the pleasures produced by both men and women from the consumption of such texts. The theoretical perspective of cultural studies informs this project, an approach that focuses on the generation and circulation of meanings in society. Focusing on the notion of the active audience and Hall's encoding/decoding model, this study examines readers' interpretations of the Men's Health text, focusing on the moment of consumption in the circuit of culture. Reception theory proposes the existence of "clustered readings" produced by interpretive communities that are socially rather than individually constructed. As a critical ethnography, the study interrogates these meanings with particular reference to questions of gender relations and power in society. Access to different discourses is structured by the social position of readers within relations of power and this study takes gender as a structuring principle. Therefore, this study also explores the particular discursive practices through which masculine and feminine imagery is produced by the Men's Health text and by its readers. The research findings support the more limited notion of the active audience espoused by theorists such as Hall (1980) offering further evidence to suggest that readers produce readings other than those preferred by the text and that therein lies the pleasure of the text for male and female readers. The research concludes that the popularity of Men's Health derives from the capacity of its readers to make multiple meanings of the text.

- Description: Over the past few decades, it has become widely recognized that the management strategies of world fisheries must ensure sustainability of bycatch as well as of target species. South Africa implemented a pilot observer programme from 1995 to 2000 to collect data on the levels and patterns of bycatch and discards in the demersal trawl fishery. Here, the results of that programme are used in conjunction with information on bycatch value and compliance to assess the issues and problems regarding bycatch and discarding in the fishery. In general, bycatch components can be placed into one of three categories (discarded bycatch, retained bycatch, and processing waste), each of which present different management problems and require different management approaches. The results were used to formulate a bycatch management plan for the demersal trawl fishery in South Africa. Given the need to continue monitoring bycatch, the performance of the pilot observer programme is reviewed, and the levels of sampling effort required for a national programme are discussed.

- Description: This study focuses on the concept or phenomenon of nihilism, given the regularity with which it manifests itself (to anyone who is aware of it in more or less theoretical or philosophical terms) in all kinds of cultural artifacts such as films, television shows or series, books such as novels or philosophical texts, and magazines. Most of these artifacts can be grouped together under the heading of the media in the present era. The objective of the study is to use the concept of nihilism to identify and analyse selected cases in contemporary media -- in the form of films and television series – to answer the question, with what kinds of nihilism people would come face to face if they knew how to recognize them. The study begins with an outline of a theoretical framework concerning the concept of nihilism. A number of thinkers’ work is used to come to grips with the complex phenomenon, but mostly it is Nietzsche whose thought seems to be valuable for present purposes. In the second chapter the spotlight falls on what is called (in this study) ‘capitalist nihilism’, which seems to belong with what Nietzsche called ‘passive nihilism’, but also seems to exhibit some aspects of ‘active nihilism’. The third chapter is an examination of nihilism in a foreign (Japanese) culture by concentrating on Japanese anime, to test the differences between Western (historically Christian) culture and one with a different cultural and religious history. The last chapter consists of the analysis of a specific (Western) film, I ‘heart’ Huckabees, which was selected because of the variety of ‘nihilisms’ found in it. The study seems to confirm that nihilism is indeed widespread in contemporary, postmodern culture.

- Description: The security of its citizens is often regarded as the democratic state's primary raison d'etre. However, with increasing crime and perceptions of insecurity among citizens, along with actual and perceived state policing inadequacies, citizens around the world have sought to make alternative arrangements for their security. The explosion of private alternatives to state policing has resulted in the need for the replacement of former static definitions of policing by more fluid understandings of what policing entails. Policing is no longer an activity undertaken exclusively by the 'state police.' Policing needs to be understood within a framework which recognises the existence of a variety of state, commercial, community groups and individuals which exist within loose and sometimes informal, sometimes formal, networks to provide for the security of citizens. Preceding the country's transition to democracy in 1994 'state' policing in South Africa was aimed at monitoring and suppressing the black population and as a result it conducted itself in a largely militaristic way. When the government of national unity assumed power in 1994 it was indisputable that the South African Police had to undergo major reform if it was to play an effective, co-operative and accountable role in a democratic South Africa. While state policing has unquestionably undergone enormous changes since the advent of democracy in 1994, so too has non-state policing. It is widely accepted that the dividing line between state and non-state policing in South Africa is increasingly blurred. Policing, by its very nature, holds the potential to threaten democracy. Consequently it is important that policing is democratically controlled. According to the Law Commission of Canada four values and principles - justice, equality, accountability, and efficiency - should support policing in a democracy. This thesis is a case study of policing in Grahamstown, a small city in South Africa's Eastern Cape province. It will be shown that the policing problem that currently plagues Grahamstown, and by extension South Africa, is not simply the result of a shortage of providers but rather a problem of co-coordinating and monitoring security governance to ensure that the city does not further develop into a society where the wealthy have greater access to security than the poor.

The Portfolio consists of seven (7) key parts. The reader of this Portfolio is courteously informed that the structure of this portfolio is to some extent differ from the thesis structure. Thus, the reader should be attentive not to weigh against the two. Further more, I hereby declare that this portfolio is my own work and that all the sources that I have used or quoted have been indicated and acknowledged by means of references indicated at the end of each part. Part 2 and 6 are the core parts of the portfolio. The focal point of part 2 is the contextual curriculum analysis of Grade 8-10 Oshindonga Curriculum in order to investigate its implementation in four educational circuits: Oshigambo, Onathinge, Onyaanya and Omuthiya in Oshikoto Region. Based on the findings of this analysis, lack of critical inquiry and reflective practice among Oshindonga teachers was identified as one of the major obstacles that preventing the effective implementation of the curriculum. Most of these teachers are Basic Education Teacher Diploma (BETD) postgraduates. Thus, part 3 and 4 were developed as supplements to inform the main research paper (part 6) which is related to teacher's professionalism in the classroom. The focus of part 3 (literature review) was on the teacher as a reflective practitioner. This is in line with the Namibian Education Policy, which identifies reflective practice as the heart of teacher professionalism. In this part, I explored a variety of views related to the notion of professionalism in teaching. I have also focused on views related to teacher's professional development both on macro and micro levels. These views provided a clarification and an underpinning framework on which to base my analysis of reflective practice as professionalism in education. Part 4 (education theories) focused on the digging of understanding of knowledge as an important theoretical domain of behaviourist and constructivist theories. I have tried to establish how the two theories (Behaviourist and Constructivist) view knowledge and its acquisition and to gain an understanding of how the two theories have been informing the practice. Subsequently, part 6 meant to investigate and assess the extent to which Basic Education Teacher Diploma postgraduate teachers are autonomously applying the theory of critical inquiry and reflective practice in the classroom. Both part 2 and 6 have findings. There is much correlation between the issues and problems in the implementation of the curriculum as identified in part 2 and the findings of the main research paper (part 6). Though critical inquiry and reflective practice is the key journey towards a high level of reflectivity and one of the significant characters of teacher professionalism in the classroom, most issues and problems identified were related to the insufficient practice of critical inquiry and reflective practices. Low correlation was found between critical inquiry and reflective practice theory and teachers' practices in the classroom. Despite to the fact that various rationales were mentioned as to why critical inquiry and reflective practice successful implementation is not taking place, the study positioned an emphasis on team working at school, cluster and circuit base that could contributed to a great extend to making teachers more competent and supporting themselves in mastering the applicable critical inquiry and reflective practice skills.

Maximum likelihood and Bayesian approaches to stock assessment when data are questionable

- Description: This study examines the use of age-structured maximum likelihood and Bayesian approaches for stock assessment of the Namibian monkfish, Lophius vomerinus, resource with questionable data, in which time series are short, abundance indices are variable, and research data conflict with commercial data. Bayesian approaches with both noninformative and informative priors are investigated to determine if they enhance estimation stability. Three data scenarios are assessed: commercial and research survey data, research survey data only, and commercial data only. Both statistical approaches show that resource abundance has decreased with exploitable biomass estimated at approximately 44% of pristine levels. The maximum likelihood and the Bayesian approach with noninformative priors result in similar estimates. As the abundance data contained little information pertaining to possible density dependence within the stock–recruit relationship, only a Bayesian approach with informative priors reduces uncertainty in the steepness parameter h. Estimated management quantities are sensitive both to the set of data sources and whether prior information was informative or not. The strengths of the Bayesian approach include the integration of prior information with uncertain data, the exploration of data conflicts, and the ability to show the uncertainty in estimates of management parameters. Its weakness is that estimation stability is dependent on the choice of priors, which alters some posterior distributions of management quantities.

- Description: This study examines the use of age-structured maximum likelihood and Bayesian approaches for stock assessment of the Namibian monkfish, Lophius vomerinus, resource with questionable data, in which time series are short, abundance indices are variable, and research data conflict with commercial data. Bayesian approaches with both noninformative and informative priors are investigated to determine if they enhance estimation stability. Three data scenarios are assessed: commercial and research survey data, research survey data only, and commercial data only. Both statistical approaches show that resource abundance has decreased with exploitable biomass estimated at approximately 44% of pristine levels. The maximum likelihood and the Bayesian approach with noninformative priors result in similar estimates. As the abundance data contained little information pertaining to possible density dependence within the stock–recruit relationship, only a Bayesian approach with informative priors reduces uncertainty in the steepness parameter h. Estimated management quantities are sensitive both to the set of data sources and whether prior information was informative or not. The strengths of the Bayesian approach include the integration of prior information with uncertain data, the exploration of data conflicts, and the ability to show the uncertainty in estimates of management parameters. Its weakness is that estimation stability is dependent on the choice of priors, which alters some posterior distributions of management quantities.
