- 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.

Investigating a rural community's use of communication technology: a study of Nakaseke Community Multi-media centre in Uganda

- Description: An assumption that Information and Communication Technologies (ICTs) and economic development have an automatic linkage has gained wide acceptance over the last decade. As a result, developing countries are under pressure to apply this prescription as a solution to poverty. With the help of development partners in the developed world and the United Nations, developing countries have embraced this call to increase access to ICTs to bridge the ever-widening gap between the ‘information rich’ and ‘information poor’ (Castells, 2001). One of the strategies has been the establishment of telecentres where the least privileged people might access ICTs for their own development needs. However, this strategy has tended to overlook contextual factors and circumstances in developing countries. ICTs are thus being introduced in an environment of mass poverty, illiteracy and poor infrastructure, exacerbating existing inequalities in some cases. Much attention has been focussed on initiatives aimed at expanding the ICT infrastructure for wider population access without addressing what the users actually do with such access. This study aims to make a contribution in that direction. The study focuses on Nakaseke Community Multi-media Centre(CMC), the first telecentre introduced in Uganda in 1997. Using a combination of quantitative and qualitative research techniques, the study sets out to develop deeper insights into how the Nakaseke community uses, engages with and relates with communication technologies installed at the telecentre. It probes whether these practices advance the dominant view that ICTs are a panacea for rural development. The findings indicate that while access to communication technology has expanded, albeit at a slow pace, the benefits might take very long to have a significant effect as many targeted users do not make use of the facilities because they lack the human skills and financial resources to exploit the technologies. Other problems such as poor electricity supply and sustainability also actively militate against the potential of the project to deliver. Besides, people tend to appropriate technology in ways different from those intended by its promoters. As Burton (2002) explains through the concept of ‘affordances’ and ‘culture’, some users perceive technologies essentially as something that bestows the status of being modern or sophisticated on their community, rather than as a development tool. In conclusion, it is argued that if used for development, ICTs can indeed make a difference in the lives of rural people. However, besides investing in technology, there is need to invest more in empowering the people themselves with skills, particularly literacy, to enable them use ICTs productively.

- Description: Since independence in 1990, various efforts have been made to improve the quality and management of Namibian schools, including the Basic Education Project (BEP-Project). In collaboration with the Geselschaft fur Technische Zusammenarbeit (GTZ), the BEP-Project has supported the implementation of important Government programs, such as Lower Primary reform and the cluster system. In 1995 the BEP-Project began to address educational needs in the Rundu education region. It was believed that Rundu had in the past been the most neglected region, especially with regard to education. The school cluster system was devised to facilitate new ways of education service delivery and to address the question of improving education standards. The purpose of this research is to answer the question: "How do the management and staff of a secondary school in the Rundu region of education experience a school cluster system?" To this end, the research seeks to determine what potential the cluster system holds and how that may be realised, and to also establish whether there is any evidence of change in management practices. A case study method has been employed to gain insight into the cluster system as a management tool. Ten respondents, all of whom have been employed at the school in question for a considerable period of time, were interviewed before and after the implementation of the cluster system. The research disclosed that disparities and tension in the school were legacies of the colonial education system, but that the cluster system had bridged the gap and enhanced uniformity and cooperation. Sharing of ideas on educational issues and constant interaction created a conducive environment for academic performance. The case study further disclosed that parental involvement in decision making is still a course for concern and that the cluster system has not yet addressed this issue. The study has shown that decentralisation has taken place and that rural schools are no longer operating in isolation. A lack of innovative ideas has hampered training as a cluster activity. From the research, it is evident that schools have previously operated on an individual basis, but that the cluster system has created the opportunity for schools to interact on a regular basis. This study is timely and of national importance. I anticipate that this study will be of use to policy makers in making decisions for the future development of the cluster system.

- Description: In terms of the common law contract of employment an employee who is a party to a fixed term contract, unlike an indefinite period contract, cannot be dismissed. The contract terminates upon an agreed or ascertainable date determined by the parties and the conclusion of the contract. Section 186(1)(b) of the Labour Relations Act 1995, however, defines the failure to renew a fixed term contract on the same or similar terms where the employee reasonably expected the contract to be renewed, as a dismissal. In this treatise the scope and content of this provision is considered with reference to relevant case law. The factors and considerations that establish a reasonable expectation are highlighted and considered. The question as to whether or not this provision also provides for the situation where an employee expects indefinite employment is also considered and critically discussed. The author concludes that the provision should not be interpreted in such a manner that an expectation of permanent employment is created.

- Description: This study sought to investigate the effectiveness of a ‘good news’ magazine like Eastern Cape Madiba Action in promoting positive attitudes towards the Eastern Cape province as an aid to development. It investigated whether Madiba Action had any effects on its readership in terms of creating positive perceptions of the Eastern Cape as a first step towards attracting tourism and investment. This quantitative research gathered attitudinal data from readers and stakeholders via two survey questionnaires. Both stakeholders and readers expressed very positive perceptions of Madiba Action magazine as a credible source of positive information about the Eastern Cape. Readers stated that the media was the greatest influence on their perceptions of the Eastern Cape and reported that Madiba Action had positively influenced their perceptions of the province as a place to visit, live, work and invest in. Whether Madiba Action as a ‘good news’ magazine went beyond positively influencing perceptions of the Eastern Cape and actually affected behaviour in terms of increased tourism and investment was beyond the scope of this study but it does provide further opportunities for measuring the role of ‘good news’ media in assisting economic development.

- Description: The proliferation of PALs (Public Access Locations) is fuelling the development of new standards, protocols, services, and applications for WLANs (Wireless Local Area Networks). PALs are set up at public locations to meet continually changing, multiservice, multi-protocol user requirements. This research investigates the essential infrastructural requirements that will enable further proliferation of PALs, and consequently facilitate ubiquitous computing. Based on these requirements, an extensible architectural framework for PAL management systems that inherently facilitates the provisioning of multiple services and multiple protocols on PALs is derived. The ensuing framework, which is called Xobogel, is based on the microkernel architectural pattern, and the IPDR (Internet Protocol Data Record) specification. Xobogel takes into consideration and supports the implementation of diverse business models for PALs, in respect of distinct environmental factors. It also facilitates next-generation network service usage accounting through a simple, flexible, and extensible XML based usage record. The framework is subsequently validated for service element extensibility and simplicity through the design, implementation, and experimental deployment of SEHS (Small Extensible Hotspot System), a system based on the framework. The robustness and scalability of the framework is observed to be sufficient for SMME deployment, withstanding the stress testing experiments performed on SEHS. The range of service element and charging modules implemented confirm an acceptable level of flexibility and extensibility within the framework.

- Description: Women in leadership has become an increasingly popular area of research within the field of Educational Leadership and Management. As women hold more leadership roles and responsibilities in education it is increasingly important this subject is researched to enrich our understanding and knowledge of an area in which there have been silences. This research is a case study of a woman school leader in Namibia. The purpose was to explore the language she used and the impact of the discourses emerging from the text. The discourses are explained, described and interpreted through a critical discourse analysis to examine the discursive space and its relationship to the organisation. A feminist post-structural framework provided the basis for the critical orientation of this research. The findings of this study indicate that the leader occupied a discursive space of multiple positions that perpetuated and reproduced the school’s organizational structure and culture. The significance of this study lies in the possibilities for future research. The use of a poststructural framework to critically analyze discourses, combined with the use of leadership and management theory provided a means by which to explore and understand the multiple positions a woman leader takes up. By analyzing the discursive space in a discourse researchers are able to explore new ways of examining women and leadership in education.

On the characterisation of copper indium diselenide based photovoltaic devices

- Description: Photovoltaic (PV) modules based on thin film systems of CuInSe2 (CIS) and its alloys on low cost substrates are promising candidates to meet the long term efficiency, reliability and manufacturing cost goals. The attention to the CIS solar cell technology is because of the high absorption coefficient of the solar cell absorber layer. Solar cells and PV modules are conventionally assessed by measuring the currentvoltage characteristic of the device. This thesis presents an assessment procedure developed capable of assessing the device parameters with reference to I-V measurements. This thesis then characterizes the performance of the CIS based solar cells and modules in conjunction with other PV modules of different technologies such as crystalline Silicon modules by analyzing the light and dark I-V measurements of the devices. The light and dark I-V characteristics of PV devices were investigated and device parameters were extracted from the I-V data. The extraction and interpretation of these device parameters has a variety of important applications. It has been proven that the device parameters can be used for quality control during production and to provide insights into the operation of the PV devices, thereby improving the efficiency of the devices. The assessment comprises light I-V measurements at standard test conditions (STC), irradiance dependence measurements, parasitic series and shunt resistances measurements and the dark I-V measurements of the PV devices. The PV modules assessed comprise different technologies, namely, thin film based modules (CIS and a-Si) and multicrystalline Si and Edged-defined Film-fed Growth Si (EFG-Si). The dark I-V measurements results showed that the EFG-Si module has acceptable shunt (900 W) and series (0.4 W) resistances, thereby leading to the higher power output depicted from the light I-V measurements. The low quality cells of a-Si module were so low that the fill factor was the smallest (43%). In addition, the dark I-V measurements results revealed that CIS modules are less dependent to temperature at high voltages.

The assessment comprises light I-V measurements at standard test conditions (STC), irradiance dependence measurements, parasitic series and shunt resistances measurements and the dark I-V measurements of the PV devices. The PV modules assessed comprise different technologies, namely, thin film based modules (CIS and a-Si) and multicrystalline Si and Edged-defined Film-fed Growth Si (EFG-Si). The dark I-V measurements results showed that the EFG-Si module has acceptable shunt (900 W) and series (0.4 W) resistances, thereby leading to the higher power output depicted from the light I-V measurements. The low quality cells of a-Si module were so low that the fill factor was the smallest (43%). In addition, the dark I-V measurements results revealed that CIS modules are less dependent to temperature at high voltages.

- Description: The South African coastline comprises 3 main biogeographic provinces: (1) the cool-temperate west coast, (2) the warm-temperate south coast, and (3) the subtropical east coast. The boundaries between these regions are defined by changes in species compositions and hydrological conditions. It is possible that these affect phylogeographic patterns of coastal organisms differently, depending on the species’ ecologies and modes of dispersal. In the present study, genealogies of 3 estuarine crustaceans, each characterized by a different mode of passive dispersal and present in more than one biogeographic province, were reconstructed using mtDNA COI sequences, and the impacts of biogeographic boundaries on their phylogeographic patterns were compared. The species were (mode of dispersal in brackets): (1) the mudprawn Upogebia africana (planktonic larvae), (2) the isopod Exosphaeroma hylecoetes (adult rafting), and (3) the cumacean Iphinoe truncata (adult drifting). Two major mtDNA lineages with slightly overlapping distributions were identified in U. africana (the species with the highest dispersal potential). The other 2 species had 3 mtDNA lineages each, which were characterized by strict geographic segregation. Phylogeographic breaks in U. africana and E. hylecoetes coincided with biogeographic boundaries, whereas the phylogeographic patterns identified in I. truncata may reflect persistent palaeogeographic patterns. Ecological factors and modes of dispersal are likely to have played a role in both cladogenesis of the different lineages and in the establishment of their present-day distribution patterns.

- Description: The last decade has seen an exodus of South African nurses migrating to "greener pastures". As a result of this migration, the South African Healthcare Service has been drained of one of its most essential resources – nurses. Subsequently, the crippling flight of nurses has thrown the nursing profession into a state of crisis. The Kingdom of Saudi Arabia is one of the more popular destinations for South African nurses, the main reason being the attractive financial rewards. One agency reports that they send an average of thirty nurses a month to various hospitals within the Kingdom of Saudi Arabia. Saudi Arabia is an Islamic country. Due to the uniqueness of the enforcement of the Islamic faith and the Saudi culture, many restrictions are imposed, particularly on women. The challenges and problems facing the South African nurses were, therefore, unique compared to elsewhere in the world. This research study had a primary and a secondary objective: The primary objective of this study was to explore and describe the lived experiences of South African nurses related to living and working in Saudi Arabia; The secondary objective of this study was to develop orientation guidelines to support South African nurses working and living in Saudi Arabia. The researcher utilized a qualitative, explorative, descriptive and contextual design based on a phenomenological approach to inquiry, in an attempt to answer the question: "What are the professional and personal experiences of the South African registered nurses working and living in Saudi Arabia?" Eleven registered nurses were selected to participate by means of purposive sampling. These nurses had been living in Saudi Arabia between three and six months. Consent was obtained from participants and the ethics committee of both the Nelson Mandela Metropolitan University and King Faisal Specialist Hospital and Research Centre. The central theme emanating from the study was recognized as being 'Cultural Diversity'. The sub-themes identified related to the registered nurses’: - Religious/spiritual adaptation - Environmental adaptation - Emotional/psychological adaptation - Professional adaptation Based on the identified themes, guidelines were formulated to assist South African registered nurses when migrating to Saudi Arabia. Utilization of these should assist the South African registered nurse in assimilating into both the cultural and working environment. However, in reality, the outcome showed that no one can be prepared fully for what awaits them in Saudi Arabia.

- Description: The electrochemical and spectroscopic behavior of tantalum(V) phthalocyanine are presented. The NMR spectra is consistent with the lack of symmetry of the complex. Cyclic (CV) and square wave (SWV) voltammetries, and spectroelectrochemistry, were employed in the study of the complex. Two one-electron reductions and a simultaneous 4-electron reduction were observed. Reduction occurs first at the metal to form a Ta(IV) species, followed by ring based processes.

Complexes 5a and 5b are substituted at the non-peripheral (α) positions, whereas complexes 6a and 6b are substituted at the peripheral (β) positions. Cyclic voltammograms of all four complexes are similar, with three reversible reduction couples and three quasi-reversible to irreversible oxidations. The first two reductions are two-electron processes, confirmed by spectroelectrochemistry to be due to TiIVPc−2/TiIIPc−3 and TiIIPc−2/TiIPc−3 redox processes. Spectroelectrochemistry showed that upon oxidation, the molecule decomposes. Oxidation is expected to occur at the ring. Chronocoulometry confirmed two electron transfer at the first and second reduction steps; and a one electron transfer at the third reduction.

- Description: This thesis explores various dilemmas in making theatre performances in the context of social disruption, trauma and death. Diverse discourses are drawn in to consider issues of body, subjectivity and spectatorship, refracted through the writer’s experiences of and discontent with making theatre. Written in a fractal-like structure, rather than a linear progression, this thesis unsettles discourses of truth, thus simultaneously intervening in debates about the epistemologies of the body and of theatre in context of the academy. Chapter 1: Methodological Anxieties Psychoanalytic theory provides a way in for investigating the dynamics of theatrical performance and its corporeal presence, by focusing on desire and its implication in the notions of loss and anxiety. The theories of the unconscious and the gaze have epistemological implications, shifting definitions of “presence” and “truth” in theatre performance and writing about theatre. This chapter tries to outline the rationale for, as well as to enact, an alternative methodology for writing, as an ethical response to loss that does not insist on consensus and truth. Chapter 2: (Refusing to) Look at Trauma This chapter examines the politics that strives to make suffering visible. Discursive binaries of public/private, dead/living, and invisible/visible underlie the politics of AIDS and sexuality. These discourses impact on the reception of Bill T. Jones's choreography, despite his use of modernist artistic processes in search of a bodily presence that aims to collapse the binary of representation (text) and its subject (being). The theory of the gaze shows this politics to be a phallocentric discourse; and narrative analysis traces the metanarrative that results in the commodification of oppositional identities, so that spectators participate in the politics as consumers. An ethical artistic response thus needs to shift its focus to the subjectivity of the spectator. Chapter 3: The Screen and the Viewer’s Blindness By appealing to a transcendent reality, and by constituting spectators as a participative community, ritual theatre claims to enact change. The “truth” of ritual rests not on rational knowledge, but on the performer’s competence to produce a shamanic presence, which director Brett Bailey embraces in his early work. Ritual presence operates by identification and belonging to a father/god as the source of meaning; but it represses the loss of this originary wholeness. Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

- Description: Real exchange rates have important effects on production, employment and trade, so it is crucial to understand the factors responsible for their variations. This study analyses the main determinants of the real exchange rate and the dynamic adjustment of the real exchange rate following shocks to those determinants, using quarterly South African data covering the period 1975 to 2005. It begins with a review of literature on the determinants of the real exchange rate and provides an updated background on the exchange rate system in South Africa. An empirical model linking the real exchange rate to its theoretical determinants is then specified. In contrast to previous analyses, this study augments the cointegration and vector autoregression (VAR) analysis with impulse response and variance decomposition analyses to provide robust long run effects and short run dynamic effects on the real exchange rate. The variables that have been found to have a long run relationship with the real exchange rate include the terms of trade, real interest rate differential, domestic credit, openness and technological progress. The estimate of the speed of adjustment coefficient found in this study indicates that about a third of the variation in the real exchange rate from its equilibrium level is corrected within a quarter. The impulse response functions broadly corroborate the theoretical predictions, but only the terms of trade, domestic credit and openness have a significant impact on the real exchange rate in the short run. However, only shocks to the terms of trade and domestic credit have persistent effects on the real exchange rate. Results from the variance decompositions are largely similar to those from the impulse response analysis. The terms of trade, domestic credit and openness are the only variables found to significantly explain the variation in the real exchange rate. The most interesting result that emerged from this analysis and is supported by previous research is that among other determinants, the terms of trade explain the largest proportion of the variation in the real exchange. On balance, the evidence therefore suggests that real exchange rate fluctuations are predominantly equilibrium responses to real and monetary shocks rather than fiscal policy shocks.

- Description: Introduction and Relevant Details: This research investigates the impact of inbound logistics' activities on the operational performance of the business within the branches of the South African Post Office (SAPO) in the Eastern Cape Province. The study basically hypothesises a statistically significant positive correlation between inbound logistics' activities and the operational performance of the business with regards to revenue generation and operational costs in particular. A sample of 100 branch offices was randomly selected. A 50-item questionnaire was administered by mail to the branches to collect the data during September 2005, and statistical tests for correlation were conducted on at least five dependent variables; stock procurement costs, effects on revenue, number of stock variation occurrences, order variation occurrences and the stock holding effects. Results of Data Analysis: The results of 88 respondents (88%) showed the existence of the significant positive relationship between the inbound logistics activities and the operational performance of the business at the South African Post Office branches as proposed by the study. The Spearman Rank Correlation tests were above 0.7 for most of the tested variables, showing a strong relationship. The inbound logistics' activities were also found to be positively correlated to revenue generation as well as to the operational expenses of the business. Conclusion and Recommendations: The findings allowed the researcher to conclude also that whatever improvements are made to the inbound logistics will also impact on the operational performance of the business, while failures in the inbound logistics will do so negatively. Business endeavours to maximise revenue and minimise costs are directly affected by the inbound logistics' activities. The branches of the SAPO seemed to be dissatisfied with most of the services rendered by the Supply Distribution Centre (SOC) of the SAPO, and such services have negatively affected the achievement of revenue targets at the branches as well as the operational costs. Holistic approaches to developing positive perceptions in the branches together with improving service activities at the SOC are recommended. Collaborative initiatives between branches and the SOC, reviewing the lead-times and the establishment of proper structures to handle supply chain queries, enhanced by information system technology to provide accurate and up-to-date information to branches and related parties about stock order issues are required . Areas of further research highlighted include the inbound logistics' activities of the SOC and the effectiveness of company policies as a guide to Supply Chain Management (SCM).

- Description: Introduction and Relevant Details: This research investigates the impact of inbound logistics' activities on the operational performance of the business within the branches of the South African Post Office (SAPO) in the Eastern Cape Province. The study basically hypothesises a statistically significant positive correlation between inbound logistics' activities and the operational performance of the business with regards to revenue generation and operational costs in particular. A sample of 100 branch offices was randomly selected. A 50-item questionnaire was administered by mail to the branches to collect the data during September 2005, and statistical tests for correlation were conducted on at least five dependent variables; stock procurement costs, effects on revenue, number of stock variation occurrences, order variation occurrences and the stock holding effects. Results of Data Analysis: The results of 88 respondents (88%) showed the existence of the significant positive relationship between the inbound logistics activities and the operational performance of the business at the South African Post Office branches as proposed by the study. The Spearman Rank Correlation tests were above 0.7 for most of the tested variables, showing a strong relationship. The inbound logistics' activities were also found to be positively correlated to revenue generation as well as to the operational expenses of the business. Conclusion and Recommendations: The findings allowed the researcher to conclude also that whatever improvements are made to the inbound logistics will also impact on the operational performance of the business, while failures in the inbound logistics will do so negatively. Business endeavours to maximise revenue and minimise costs are directly affected by the inbound logistics' activities. The branches of the SAPO seemed to be dissatisfied with most of the services rendered by the Supply Distribution Centre (SOC) of the SAPO, and such services have negatively affected the achievement of revenue targets at the branches as well as the operational costs.

- Description: This treatise is a study of the methodology and the thought processes followed when buildings are designed, in order to determine to what extent, if any, designers consider the need for buildings to be maintained long after they walk off site and part with the project. The concept of taking future maintenance requirements into account as part of the design process is referred to as “designing for maintenance” (DFM). It can be assumed that, from a professional perspective, designers must keep the client’s needs in mind when designing. Facilities managers face the challenge of balancing a budget with maintaining a functional building – a dream building would be a maintenance-free building. Armed with the knowledge of DFM it is hoped that future buildings will be designed in a manner that will facilitate maintenance, thereby achieving significant savings on the life cycle costing of buildings. Buys (2004) suggests that designers should adopt a more open-minded approach toward maintenance during the design stages of buildings. Maintenance, with reference to access, methods, material and funding, could benefit from this approach, with a positive effect on the life cycle costing of a building. In order of priority when starting a building project, the design process is at the top of the list. Because this process happens right at the outset of a project, it is important to address the level of maintenance awareness that goes into designing, at this stage. The research concludes that one of the methods which could have a permanent effect on designers’ awareness of DFM would be to include it in the subjects taught at schools where designers are trained. This idea was discussed with a number of lecturers in this field and they were all in favour of this approach. There is a perception that built environment practitioners and professionals such as architects and contractors in the various fields related to the built environment, often engage in their particular task as if they exist in isolation from the project as a whole and from the rest of the project team. However, it is becoming increasingly evident that all built environment aspects are interwoven and interlinked, and that all are part of a larger context. With reference to the built environment as a whole, no action or element exists in isolation from a larger web of activity. The challenge, to nurture within students an awareness of the range and interconnectedness of elements and processes that contribute to the holistic idea, rests with the educators in the design fields, because it is clear that the final impact of any project relies to a large extent on what was specified by the designers in terms of materials and construction methods. The impact of the world’s six billion inhabitants on the environment is clearly a critical issue but does little to influence the actions of most design professionals. Documented experiences should serve as valuable tools to guide designers towards making more educated decisions on building design. Built environment professionals should educate themselves about the range of issues involved in the analysis, design and production of the built environment and the interaction between these factors.

- Description: Syncarpha recurvata (L.f.) B. Nord. (Asteraceae, Gnaphalieae) is listed as a vulnerable (intermediate priority) species. The propagation methods of achene germination, stem cuttings, air layering and micropropagation were investigated to obtain an efficient propagation method. Smoke water dilutions of 1:100, 1:50 and 1:10 significantly increased germination, with the 1:100 smoke water dilutions showing the highest germination percentage (22.4 percent). Achenes collected between August and October 2005 showed higher germination and viability than achenes collected between May and July 2006. Fifty percent of the stem cuttings and 32 percent of the airlayered branches rooted. Embryo culture was the only successful culture type out of the four attempted. Two embryos germinated and four became photosynthetic. Two of the germinated embryos also produced callus cells, a medium supplemented with 5 μM IAA may be used to test for a suitable plant regulator for organogenesis or embryogenesis. Syncarpha recurvata plants were also transplanted into pots and 60 percent survived. A growth rate of 1.466 mm y-1 was obtained from total shoot length measurements. In this study, it was found that air-layering branches of transplanted Syncarpha recurvata plants is the most efficient propagation method.
