- Description: The optical behavior of bis-{2(3), 9(10), 16(17), 23(24)-(tetrapyridin-4-yloxy phthalocyaninato)} lanthanum (III) (2) and its ytterbium (3) counterpart in dimethyl sulfoxide are presented and compared to bis-{1(4), 8(11), 15(18), 22(25)-(tetrapyridin-4-yloxy phthalocyaninato)} ytterbium (III) (4). We report on the third-order susceptibility, second-order hyperpolarizability and the limiting threshold values. The nonlinear optical limiting threshold values of complexes 2, 3 and 4 showed improvement in the solid state (thin films), with complex 4 giving the best value at 0.033 J cm−2.

- Description: This work presents the development of a multifunctional hybrid nanoparticle made of L-glutathione capped quantum dots (GSH-CdSe@ZnS), amino functionalized Fe3O4 magnetic nanoparticles and indium octacarboxy phthalocyanine (ClInPc(COOH)8). In this work we investigate the photophysical properties of the individual components and the hybrid nanoparticle, in addition we study the energy transfer (Förster Resonance Energy Transfer (FRET)) in the complex. FRET efficiencies of ~48 % were obtained for energy transfer between the QDs (when alone or linked to MNPs). Both triplet yields and lifetimes of ClInPc(COOH)8 increase in the nanocomposite, with a decrease in fluorescence lifetime. The hybrid nanoparticle showed improved photophysical properties and as a result can be used in photodynamic therapy.

- Description: According to the former president of the International Federation of Theatre Research (IFTR), Brian Singleton, the study of ‘[i]nterculturalism as a practice and a theory gained currency with Richard Schechner’s anthropologically-inspired new discipline of performance studies’ (p. 79). Schechner’s new discipline led to the formation of the annual Performance Studies International (PSI) conferences, and earlier this year I attended the twentieth instalment in Shanghai, which was held under the rubric of ‘Tradition and the Avant-Garde’. One of the things which struck me was the extent to which the (relatively) newly economically empowered Chinese theatre makers were creating grand productions based on Western theatre traditions. For example, many of the presentations for delegates were based on Western texts (such as Hamlet, Miss Julie and even a play by Woody Allen). And yet these productions were performed in Mandarin, using purist Chinese forms, such as Beijing Opera. During the discussions there seemed to be an awkward defensiveness from some of the Chinese hosts who insisted they were not ‘copying’ Western theatre, but that they were using it to express a pure Chinese aesthetic. There were also other performances at the conference, such as a series of parables called Confucius Disciples, which told didactic tales with content very foreign to a Western audience. A visiting troupe from Bulgaria presented their own version of some of these parables, using a strongly East European aesthetic to convey a Chinese message. In this way, experiments with cultural forms and content were clearly foregrounded by the conference presentations.

- Description: The background to the present discussion is the prevalence of political and personal criticisms in philosophical discussions about Africa. As philosophers in South Africa—both white and black—continue to philosophise seriously about Africa, responses to their work sometimes take the form of political and personal criticisms of, if not attacks on, the philosopher exploring and defending considerations about the African continent. One of us (TM) has been the target of such critiques in light of his work. Our aim in this conversation is not to diminish or deflect such critiques. On the contrary, our aim is to understand them, to make them as strong as possible, and to bring them into the cooler realm of philosophical discussion.

- Description: Optimisation of the benefits from urban forestry and greening to urban dwellers and the environment rests on proactive and appropriate management planning, implementation and resourcing. Yet, lessons from the developed world show marked variability in development and adoption of urban tree and green space (UTGS) strategic plans and systematic monitoring and maintenance. Although financial and human resources for UTGS may be constrained in developing world contexts, there is no knowledge of the extent to which local authorities engage in appropriate and timely planning, management and monitoring. Here we examine the UTGS resourcing, planning, maintenance and integration across 28 local municipalities in the two poorest provinces in South Africa. It was revealed that most local municipalities were not managing their UTGS in a planned or systematic manner due to constraining factors such as insufficient funds, insufficient personnel, lack of equipment and lack of political support. Only 7% of the surveyed municipalities had an urban tree management plan and an estimate of the urban tree stock; 32% had tree policies; 21% had tree planting schedules; 11% had tree maintenance schedules. Over 65% claimed to engage other stakeholders in tree planting, but much was passive receipt of trees for planting rather than citizen engagement around species, places and values. Generally, the prevalence of most planning and maintenance elements increased with increasing size of the municipality and the presence of personnel specifically for UTGS management. It is likely that the prevalence of planning and maintenance functions will increase with greater political support from municipal councillors which may also decrease funding challenges.

- Description: International relations has recently seen new developments which are unpredictable and in their infant stage. The causes of these developments are plentiful, the consequences stemming from waning unipolarity to the emergence of new fora creating their own spaces. Whatever the case, international relations is not as it was in the period just after the Cold War. As a result, the terms of global governance established after 1990 have come under serious scrutiny. This transition has the makings of a new world order, an interpolar world order. This study asserts that we no longer live in a unipolar world, nor do we live in a world which can only be described as multipolar. It makes the argument that although multipolarity is a crucial element of the world, it only offers a partial description of today’s order. The study asserts that it is interpolarity which is closest in accounting for today’s world. Not only does it describe the world as multipolar, it also describes it as interdependent. To this end, the study provides a detailed account of what is meant by an interpolar world order and how differently it explains international events. It also provides an account of factors which can develop in an interpolar world. One of these includes allowing room for emerging powers to create their own spaces in efforts of avoiding co-option while continuing to realise the importance of operating within a context of continuity. This means that emerging countries create their own spaces but they also realise the importance of working with already established regimes such as the G20. BRICS (Brazil, Russia, India, China and South Africa) is used as a case study to indicate one of the new developments afforded by an interpolar order-the emergence of new fora. The study asserts that although BRICS is rife with internal dissimilarities, it has indicated some degree of political will in one aspect; that is; advocating for the reform of the terms of global governance, advocating for more representative forms of global governance. The study thus explores factors of a world whose contours are gradually changing but which are unpredictable and in flux. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2015

- Description: Stress-inducible protein 1 (STI1) otherwise known as Hop (Hsp70/Hsp90 organising protein) is a highly conserved abundant co-chaperone of the Hsp70 and Hsp90 chaperones. STI1 acts as an adapter protein, where it regulates the transfer of protein substrates from Hsp70 to Hsp90 during the assembly of a number of chaperone-client protein complexes. The role of STI1 associating independently with non-chaperone proteins has become increasingly prominent. Recent data from colocalisation and co-sedimentation analyses in our laboratory suggested a direct interaction between STI1 and the cytoskeletal protein, actin. However, there was a lack of information on the motifs which mediated this interaction, as well as the exact role of STI1 in the regulation of cytoskeletal dynamics. Two putative actin binding motifs, DAYKKK (within the TPR2A domain) and a polyproline region (after the DP1 domain), were identified in mammalian STI1. Our data from in vitro interaction studies including surface plasmon resonance and high speed co-sedimentation assays suggested that both TPR1 and TPR2AB were required for the STI1-actin interaction, and peptides corresponding to either the DAYKKK or the polyproline motif, alone or in combination, could not block the STI1-actin interaction. Full length mSTI1 was shown to have ATPase activity and when combined with actin an increase in ATPase activity was seen. Ex vivo studies using STI1 knockdown shRNA HEK293T cells and non-targeting control shRNA HEK293T cells showed a change of F-actin morphology as well as reduction in levels of actin-binding proteins profilin, cofilin and tubulin in the STI1 knockdown cells. These data extend our understanding of the role of STI1 in regulating actin dynamics and may have implications for cell migration. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2015

- Description: The Trade in and Household Use of Phoenix reclinata Palm Frond Hand Brushes on the Wild Coast, South Africa. This paper reports on an investigation of the harvesting, trade, and use of hand brushes made from fronds of the wild palm, Phoenix reclinata. We considered both the abundance of the resource as well as the demand. Within the harvesting areas, there were approximately 141 palm plants per hectare, of which almost two-thirds showed no signs of frond harvesting. During harvesting, most fronds (82%) were left on the plant, 16% were removed to make brushes, and 2% were cut and discarded. Although the number of harvesters had increased during the last decade, most felt that the number of palm plants had remained stable or even increased over the same period. There was strong consensus that cut fronds were replaced within two months, after which a particular stem could be harvested again. Harvesting and trade were practiced largely by middle-aged to elderly women, who had limited formal education, skills, and employment prospects. Most had entered the trade because of cash income poverty. The main markets for selling the palm brushes were in nearby urban areas. The income earned from the trade was modest, but still rated highly by the traders, for most of whom it was the second most-important source of cash income. For many users, the palm brushes was found to be the only type of brush suitable for cleaning mud and cow-dung flooring and, most importantly for many, their use forms part of a long household use history and culture.

- Description: The Wild Coast of the Eastern Cape is renowned for its cultural landscapes, stunning scenery and remarkable biodiversity. It is also one of the least developed regions of South Africa, which underpins the small productive base and limited economic opportunities for the hundreds of rural communities scattered along the hilltops. It is not surprising therefore, that many inhabitants make extensive use of natural resources, such as firewood, reed mats, medicinal plants and wild vegetables, in their daily lives, as well as for sources of income when the opportunity arises.

- Description: This paper presents a case study on the severely degraded Boksburg Lake’s (Gauteng, South Africa) social–ecological system, and on an environmental-education initiative that aimed to support the lake’s transformation with a view to its improved social and ecological well-being. In this case study, three key characteristics of the initiative which appeared to support the transformative process are discussed, namely: 1. Learning was aligned with the local social–ecological context; 2. Human-to-human and human-to-ecological connections were encouraged; and 3. The youth played a key role in initiating and effecting transformation.

In this case study, three key characteristics of the initiative which appeared to support the transformative process are discussed, namely: 1. Learning was aligned with the local social–ecological context; 2. Human-to-human and human-to-ecological connections were encouraged; and 3. The youth played a key role in initiating and effecting transformation.

- Description: The nature of the sustainability challenges currently at hand is such that dominant pedagogies and forms of learning that characterize higher education need to be reconsidered to enable students and staff to deal with accelerating change, increasing complexity, contested knowledge claims and inevitable uncertainty. In this contribution we identified four streams of emerging transformative, transgressive learning research and praxis in the sustainability sciences that appear generative of a higher education pedagogy that appears more responsive to the key challenges of our time: (1) reflexive social learning and capabilities theory, (2) critical phenomenology, (3) socio-cultural and cultural historical activity theory, and (4) new social movement, postcolonial and decolonisation theory. The paper critiques the current tendency in sustainability science and learning to rely on resilience and adaptive capacity building and argues that in order to break with maladaptive resilience of unsustainable systems it is essential to strengthen transgressive learning and disruptive capacity-building.

I touched his arm, and we joked about the broad blunt strokes of the casiotone the old dame played for the lunch-eaters next door. Uncle Noodle had always been my favourite. In a world where adults were always certain, ready to disdain and judge and pass verdict – I loved it that he was indecisive, insecure, unsure. Often wretched, often defeated. His heart had chasmed in the wake of his wife‟s leaving, finally dividing him from all his hopes, collapsing his dignity destroying his happiness machinery.

- Description: This research study examined: 1. the attitudes and perceptions of female university students towards unplanned pregnancies, their (pregnancies’) associated influences and their social economic consequences on the participants and their family. 2. The level of knowledge, the sources thereof, and the girls’ attitudes and perceptions toward contraception, abortion and their actual use as possible barriers in the prevention of unplanned pregnancies. 3. The possible interventions in curbing the phenomenon of unplanned pregnancies. Data for the study was gathered through in-depth-interviews with ten female undergraduate students at the University of Fort Hare in East London campus, who had the experience of unplanned pregnancy while studying. Selection of participants was done through snowball sampling. A number of factors responsible for the unplanned pregnancy are revealed, including: Inadequate and inconsistent use of contraceptives, ignorance about contraception or rejection of contraceptive use due to religious beliefs. Influential factors regarding unplanned child bearing include: The role of the mother and the boyfriend, traditional and religious beliefs, and the desire for child bearing and motherhood. Although the majority of the girls are knowledgeable about contraception, and their right to abortion, a number of barriers hinder them from putting this knowledge into practical use. Some of the most highlighted consequences of unplanned/unwanted pregnancy are the financial burden on the family and loss of study time. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2015

- Description: Issues relating to energy use, renewable energy introduction and climate change have received a lot of attention from governments throughout the world in the past two decades. Many developing nations like South Africa heavily rely on coal and other non-renewable resources for their production of energy. The processing of the non-renewable resources into secondary energy forms is according to many energy experts a chief contributor to climate change. Climate change is affecting agricultural production in many developing countries that entirely rely on rainfall for their production. The loss in production in South Africa is increasing the level of poverty in low-income earners and unemployed people. Also a lot of households found in rural areas of South Africa have no access to electricity. Electricity in South Africa is generated and distributed by Eskom a state owned company. In April 2008 Eskom failed to meet power demand and started introducing load shedding to maintain and upgrade their power plants. The load shedding stopped for while and was introduced again in 2014 when the power utility faced the challenge of failing to produce power to meet demand again due to problems with their power stations. The ongoing energy provision problems in South Africa can be alleviated by introducing alternative sources like renewable energy. Introduction of renewable energy in poorly developed areas like Nkonkobe Municipality can help households‘ access electricity and reduce load on the national grid. The aim of this study was to locate suitable sites for setting up wind farms in Nkonkobe municipality in South Africa. Wind energy as a resource is abundant in many areas of South Africa and areas to set wind farms for optimum harness of wind power were identified using GIS, remote sensing and multi-criteria decision making techniques. Wind speed, distance from settlements, distance from main roads, distance from national, slope and land use/land cover were chosen as the factors to consider in selecting a suitable site. Data was collected from South Africa Weather Services, University of Fort Hare and online free data sources. Thematic maps for all the factors were developed in ArcGIS and fed into Nkonkobe Municipality database developed for the study. Thematic maps were assigned weights before being overlaid using weighted overlay tool. Weights for the factors were determined using Analytical hierarchy Process‘ pairwise comparison approach. Weighted overlay of the thematic maps produced a map showing suitable areas based on the weight influence of each factor. The output map was compared to results obtained from using Boolean approach and weighted sum method as a way of checking the accuracy of obtained suitable sites. Results showed there are three sites that can be used for setting up wind farms in the study area. , Thesis (MSc) (Applied Remote Sensing and GIS) -- University of Fort Hare, 2015

- Description: In this paper, I am concerned with elucidating and expanding our attitudes toward our own death. As it is, our common attitudes toward our death are the following: we fear our premature death, and we dread our inevitable death. These attitudes are rational, but I want to argue that our attitudes toward death should be more complicated than this. A condition upon our value, our preciousness, as creatures is that we are vulnerable, and our vulnerability is, at bottom, a vulnerability to death. A corollary of this is that we could not be loved, either by ourselves or by others, for one cannot love—be concerned for—a being invulnerable to death. As a consequence, death plays a deep and abiding role in our value systems. Our susceptibility to premature and inevitable death is a condition upon our being valuable creatures and, in turn, it is a condition upon our being loved. Given the high value that we place on being valuable creatures who deserve love, we should equally place a high value on the constitutive conditions for being precious and loved. If, as I suggest, one of these conditions is that we will die, we should see our deaths not simply as something to fear or dread, but as something of great importance in our lives. Our deaths should be treated with awe, respect, and even praise.

It begins by exploring the use of free writing exercises as a means of nurturing the emergence of physical (audible) voice in creative writing classes before assessing some of the ramifications and implications of the trope, both diachronically and synchronically. A key issue of this discussion is whether voice is regarded as individual or social.

- Description: This article examines women's role as combatants in national liberation forces in South Africa. Three categories – guerrilla girls, combative mothers and the in-betweeners – are introduced to underscore the varied ways in which women have participated in combat within the national liberation movements. Factors such as age and one's ability to leave the country affected whether women could participate in combat as ‘guerrilla girls’ or if it limited them to fighting apartheid violence from home, or if there were women who can be defined as having fallen somewhere in between these categories. These categories are used to theorise women's combat roles in the anti-apartheid struggle, thus broadening and challenging the dominant notions of combat that often hide women's contributions in war. In this regard, different periods of struggle, physical location, as well as age, determined the methods of activism available to men and women.
