- Description: There are a number of recent exciting developments in the Johannesburg alternative art scene. Alternative or experimental art spaces often exist as an alternative to commercial galleries and government or privately funded galleries as well as museums. They are therefore governed through a different set of rules, rules that often aim to transgress the institutional. These spaces, including the Parking Gallery, the Keleketla! Library and arguably the Wits School of Art's Substation gallery, invite debates about alternative art programming, collaborative art making and the necessity of institutional funding in order to maintain such spaces. In addition to these questions, it is pertinent to first determine what it is that classifies a space as alternative.

- Description: Developing an identity with self-esteem and a sense of self-worth is a child’s fundamental right (Vandenbroek, 2001). To encourage identity formation children need to ask and answer questions such as: ‘Who am I?’, ‘Where do I belong?’ and ‘Is it ok to be who I am?’ A child’s identity is shaped largely by his/her experiences with regards to relationships and belonging within communities and familial structures. However, South Africa faces a host of problems, including poverty, violence, HIV/AIDS, all of which contribute to the breakdown of these familial and community structures. Utilising a participatory action framework, this research aims to provide insight into how children living in a disadvantaged community negotiate identity and belonging. This insight into children’s perceptions of identity and belonging is useful for identifying resources within the community which promote a positive sense of identity and belonging, and also to identify areas where support and intervention are required. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2013

- Description: In 1996, Zimbabwean graphic designer Chaz Maviyane-Davies created a set of human rights posters which represent several articles of the Universal Declaration of Human Rights, from what he calls an “African perspective”. In this study I investigate how Maviyane-Davies has constructed ‘African-ness’ and probe what he refers to as the “alternative aesthetic” that he is trying to create. I use a visual social semiotic approach to examine the discourses he draws on to re-image and re-imagine Africa and Africans in a manner that contests the stereotypical representations found in political, news and economic discourses about Africa, paying particular attention to the ways he uses images of the body. My analysis of the posters shows how complex and difficult it can be to contest regimes of representation that work to fix racialised and derogatory meanings. In response to the pejorative stereotypes of the black body, Maviyane-Davies uses images of strong, healthy, and magnificent people (mostly men) to construct a more affirmative representation of Africa and Africans. Significantly, he draws on sports, touristic, traditional and hegemonic discourses of masculinity in an attempt to expand the complexity and range of possible representations of African-ness. In so doing he runs the risk of reproducing many of the stereotypes that sustain not only the racialised and gendered (masculinist) representations of Africa, but also a sentimentalisation and romanticisation of a place, a people and their traditions. Apart from women in prominent positions, other conspicuous absences from these images include white people and hegemonic references to Western modernity. I do not believe he is discarding whites and modernity as un-African, but is rejecting the naturalisation of whiteness as standing in for humanity, and particular icons of Western modernity as significations of ‘modernity’ itself

- Description: 1. This study outlines the development of a qualitative risk assessment method and its application as a screening tool for determining the risk of establishment and spread of the invasive Nile tilapia, Oreochromis niloticus (Linnaeus, 1758), within the central sub-catchment of the Limpopo River basin in northern South Africa. 2. The assessment used known physiological tolerance limits of O. niloticus in relation to minimum water temperature, presence or absence of dams, seasonality of river flows, and the presence of indigenous fish species of concern to identify river systems that would be suitable for O. niloticus establishment. 3. River sections along the Limpopo main river channel and the immediate reaches of its associated tributaries east of the Limpopo/Lephalala river confluence along the Botswana–South Africa–Zimbabwe border were identified as being highly vulnerable to O. niloticus invasion. Rivers in the upper Bushveld catchment (Upper Limpopo, Mogalakwena, Lephalala, Mokolo, Matlabas and Crocodile rivers) were categorized as of medium ecological risk, while headwater streams were considered to be of low ecological risk. The decrease in vulnerability between lowveld and highveld river sections was mainly a function of low water temperatures (8–12˚C) associated with increasing altitude. 4. Oreochromis niloticus is already established in the lower catchment of the Limpopo River basin where indigenous congenerics are at an extinction risk through hybridization and competition exclusion. Oreochromis niloticus, therefore, poses an ecologically unacceptable risk to river systems in the upper catchment where it is yet to establish. The current risk assessment model provides a useful preliminary framework for the identification of river systems that are vulnerable to an O. niloticus invasion where conservation measures should be directed and implemented to prevent its introduction and spread within the Limpopo river system.

- Description: Indications of poor quality in students’ written work necessitated the need for deeper investigations aimed at designing and applying appropriate teaching/learning and assessment innovations in the course curriculum. The project-exercise engaged a conceptual-explorative approach through: reviews/investigations; educational diagnosis; design/application of innovations and evaluation processes. In addition to other challenges, diagnosed problems included: students’ ignorance on key curriculum components; imbalance in teaching/learning and assessment tasks engaging all 3-learning domains; less intensiveness of the e-learning mode; and superficial formative feedback. Included a “Student-Curriculum-Discourse” self-tutorial guide, and tasks alignment of the teaching/learning and assessment. Learners’ performance can be improved through a curriculum-discourse self-tutorial exercise, complemented with: intellectual, social, experiential, and emotional structures. Both educators and learners share specific responsibilities in the teaching/learning environment. There is need to expand/probe the theoretical dimension within which the on-line distance education occurs.

A tale of two neglected systems-structure and function of the thin- and thick-walled sieve tubes in monocotyledonous leaves

- Description: There is a large body of information relating to the ontogeny, development and the vasculature of eudicotyledonous leaves. However, there is less information available concerning the vascular anatomy of monocotyledonous leaves. This is surprising, given that there are two uniquely different phloem systems present in large groups such as grasses and sedges. Monocotyledonous leaves contain marginal, large, intermediate, and small longitudinal veins that are interconnected by numerous transverse veins. The longitudinal veins contain two metaphloem sieve tube types, which, based upon their ontogeny and position within the phloem, are termed early (thin-walled) and late (thick-walled) sieve tubes. Early metaphloem comprises sieve tubes, companion cells and vascular parenchyma (VP) cells, whilst the late metaphloem, contains thick-walled sieve tubes (TSTs) that lack companion cells. TSTs are generally adjacent to, or no more than one cell removed from the metaxylem. Unlike thin-walled sieve tube (ST) -companion cell complexes, TSTs are connected to parenchyma by pore-plasmodesma units and are generally symplasmically isolated from the STs. This paper addresses key structural and functional differences between thin- and thick-walled sieve tubes and explores the unique advantages of alternate transport strategies that this 5–7 million years old dual system may offer. It would seem that these two systems may enhance, add to, or play a significant role in increasing the efficiency of solute retrieval as well as of assimilate transfer.

- Description: After many years of the oppressive apartheid government, the new democratic era came into being in 1994. Lot of policy changes came into being, including language policy. This new language policy of the post-apartheid era recognises eleven official languages which include the nine indigenous African languages which were previously recognised as regional languages in the different homelands. The present study investigates the progress of Tshivenda in terms of status and development since it was accorded the official status in South Africa. Literature investigating the status of Tshivenda is generally sparse. This study investigates the status of Tshivenda in South Africa to explore how minority languages which are also recognised as official languages are treated. In most multilingual countries, there are issues which affect the development of minority languages, but the South African situation is interesting in that some of the minority languages are recognised as official languages. This study is a comparative in nature. Firstly, the study compares the level of corpus planning and development in Tshivenda and other indigenous South African languages. Secondly, it compares how people use Tshivenda in a rural area of Lukalo Village where the language is not under pressure from other languages and in Cosmo City, an urban area in Gauteng where Tshivenda speakers come into contact with speakers of more dominant languages such as isiZulu and Sesotho. Language use in different domains like, media, education, government and the home is considered in order to establish how people use languages and the factors which influence their linguistic behaviours. The study also establishes the perceptions and attitudes of the speakers of Tshivenda as a minority and those of the speakers of other languages towards Tshivenda’s role in the different domains such as education and the media. This study was influenced by previous research (Alexander 1989, Webb 2002) which found out that during the apartheid period Tshivenda speakers used to disguise their identity by adopting dominant languages like isiZulu and Sesotho in Johannesburg. Accordingly, the present research wanted to establish how the language policy change in the democratic era has impacted on the confidence of Tshivenda speakers regarding themselves and their language. This study establishes that although Tshivenda is now an official language in post-apartheid South Africa, it still has features of underdevelopment and marginalization that are typically of unofficial minority languages. Translation, lexicographic and terminological work in this language still lags behind that of other indigenous South African languages and there is still a shortage of school textbooks and adult literature in this language. As a result, using the language in education, the media and other controlling domains is still quite challenging, although positive developments such as the teaching of the language at university level can be noted. The Tshivenda speakers generally have a positive attitude towards their language and seem prepared to learn and use it confidently as long its functional value is enhanced, which is currently not happening. As a result, some Tshivenda speakers still regard English as a more worthwhile language to learn at the expense of their language

- Description: From Introduction: Today I’m presenting some of the preliminary findings of a study about voluntary childlessness conducted with Indian, Polish, and fellow South African collaborators. Voluntary childlessness is also frequently referred to as being childless by choice or childfree. The term childfree (as opposed to ‘childless’) is intended to show that not having children “can be an active and fulfilling choice”, and to indicate agency and freedom from social obligation. The distinguishing feature of voluntary childlessness is the deliberate avoidance of parenthood, and this is precisely what opens up childfree people, especially married heterosexuals, to greater stigma than the temporarily or involuntarily childless, since it is seen as willing and deliberate deviation from the norm. Having children is seen as a natural consequence of being a “normal” heterosexual woman or man, as well as an expected outcome of marriage. Parenthood is therefore normalised by regulative discourses around sexuality and gender. This process of normalisation is reinforced by pronatalist discourse. According to Meyers, pronatalism rests upon twin strategies: The first is the valorisation or glorification of parenthood, which supports the belief that having children is the only true path to fulfilment. The second strategy is the denigration of non-reproduction in which childlessness is cast as horrific. The result of these dual strategies is to eliminate deliberate childlessness as a possibility. Parenthood, as the only truly viable option for a fulfilling life, is therefore a non-choice. This is compounded by nationalistic and religious rhetoric that constructs childbearing as an obligation or duty. Consequently, as my previous research showed, people often do not reflect on whether to have children or not, but see it more as a matter of timing.

- Description: From Introduction: Today I’m presenting some of the preliminary findings of a study about voluntary childlessness conducted with Indian, Polish, and fellow South African collaborators. Voluntary childlessness is also frequently referred to as being childless by choice or childfree. The term childfree (as opposed to ‘childless’) is intended to show that not having children “can be an active and fulfilling choice”, and to indicate agency and freedom from social obligation. The distinguishing feature of voluntary childlessness is the deliberate avoidance of parenthood, and this is precisely what opens up childfree people, especially married heterosexuals, to greater stigma than the temporarily or involuntarily childless, since it is seen as willing and deliberate deviation from the norm. Having children is seen as a natural consequence of being a “normal” heterosexual woman or man, as well as an expected outcome of marriage. Parenthood is therefore normalised by regulative discourses around sexuality and gender. This process of normalisation is reinforced by pronatalist discourse. According to Meyers, pronatalism rests upon twin strategies: The first is the valorisation or glorification of parenthood, which supports the belief that having children is the only true path to fulfilment.

- Description: Information on the movement behaviour and habitat use by non-native invasive African catfish Clarias gariepinus is crucial in understanding and possibly mitigating its potential impacts. The aim of this study was to examine catfish movement and habitat selection within an invaded impoundment in the Eastern Cape, South Africa. Acoustic telemetry data for 10 tagged catfish were analyzed to identify spatial patterns in home ranges and seasonal changes in habitat associations. Long-distance movements were observed for most catfish from common central release point, whereas short-distance movements defined their home ranges and utilization distributions that were categorized as localized within single or multiple habitats. Habitat selection was non-random with most catfish utilizing the shallow river mouth and upper section of the reservoir that were dominated by a rocky substratum interspersed with submerged trees. These localities were likely to be preferred for spawning and/or feeding. Utilization of these habitats by catfish is likely to be associated with probable impact due to predation and interference competition for feeding and breeding grounds with other species. Although most catfish maintained their home ranges throughout the study, seasonal shifts in habitat use, which was reflected by the utilization of deep and silt-dominated habitats, were also observed for some catfish. Non-random habitat use and homing behaviour within single and multiple habitats by non-native sharptooth catfish suggests that its impact within the invaded habitats may be associated with particular habitats both at broad spatial and temporal scales. Protection of habitats from catfish invasion should be considered as a management option to conserve native biota.

- Description: publisher version , A set of eight-membered benzannelated heterocycles containing two heteroatoms (O,O, NR,NR and O,NR where R=protecting group) was synthesized by ring-closing metathesis from the corresponding ortho-bis-allyl precursors. In this manner, 7-methoxy-2,5-dihydro-1,6-benzodioxocine, 1,2,5,6-tetrahydro-1,6-benzodiazocines, 5,6-dihydro-2H-1,6-benzoxazocines and 5,6,9,10-tetrahydropyrido[2,3-b][1,4]diazocine were synthesized. A number of these compounds were then treated with the catalyst [RuClH(CO)(PPh3)3] to facilitate isomerization of the alkene into conjugation with the heteroatoms in the eight-membered ring. Quite surprisingly, an equal ratio of regioisomers was obtained, even if the heteroatoms were different.

- Description: This book aims to examine the conceptions and practices of security adopted by Regional Organisations (ROs) across the globe. Since the end of the Cold War, there has been an increased focus on regions as a relevant realm for security, with actors within regional contexts identifying a significant degree of interdependency between one another. As a consequence, international security has taken on a distinct regionally institutionalised character, as seen by the increase in calls for greater utilisation of ‘Chapter VIII: Regional Arrangements’ of the UN, in order to create a devolved UN-led system of global security management. However, the idea of a system of global security management is a remote prospect, because divergence seems to be as important as commonality in terms of regional security.

- Description: Pre-print , This article represents the next in a series of five-year overviews of children’s rights in the courts in South Africa. Using the Convention on the Rights of the Child and the African Charter on the Welfare of Children as a point of departure, the study suggests that it is in the public sphere that children’s rights have had their most impact in the period under review. The article highlights eight areas of distinction in this five-year period: these include judicial approval of resource mobilisation for the fulfilment of children’s rights, emphasis on the quality of and standards in education; the development of innovative remedies to deal with unreasonable state measures affecting children, and an increasing focus on the right to dignity of the child. The authors conclude that the scope of the cases cited points to the growing insertion of children’s rights considerations in increasingly diverse areas of legal interaction. Furthermore, the authors posit that the CRC and ACRWC – together with non-binding sources of international law – have substantively informed and enriched the jurisprudence of South African courts.

- Description: publisher version , From Introduction: The world faces a food security challenge with approximately 868 million people undernourished and about two billion people suffering from the negative health consequences of micronutrient deficiencies [1]. Yet, at least one-third of food produced for human consumption is lost or wasted along the food chain between farm and fork [2–7]. Food waste refers to wholesome edible material intended for human consumption, arising at any point in the food supply chain that is instead discarded, lost, degraded or consumed by pests [8]. Food loss is defined as the decrease in food quantity or quality which makes it unfit for human consumption [9]. According to the European Commission [10], food waste is composed of raw or cooked food materials such as vegetable peelings, meat trimmings and spoiled or excess ingredients or prepared food as well as bones, carcasses and organs. However, food waste can be measured only for edible products that are directed to human consumption [6]. Food losses take place at production, postharvest and processing stages in the food supply chain and the food losses that occur at the end of the food chain (retail and final consumption) are called “food waste” [11]. In our study food waste refers to food losses that occur at the end of the food chain (final consumption at household or consumer level) which include edible products that are directed to human consumption and are discarded when not consumed for various reasons. It is related to consumers’ behaviour [6,11] and it includes food loss before, during or after meal preparation in the household. , The research was funded by VW foundation under the Livelihoods Urbanisation and Natural Resources in Africa (LUNA) project through Freiburg University, Germany.

- Description: A growing literature describes a wide range of negative impacts of climate change on marine resources and the people and communities they support, including species range changes, changes in productivity of fisheries and declines in economic performance (Doney et al. 2012; Poloczanska et al. 2013). These impacts, many of which are projected to increase in future, are compounded by growing pressures on marine resources (Halpern et al. 2008; Maxwell et al. 2013). An estimated 260 million people are involved directly or indirectly in global marine fisheries (Teh and Sumaila 2013) with many of the resources for capture fisheries already fully (&57 % in 2009) or over exploited (30 %) (FAO 2012). Nevertheless, production of marine resources will need to increase to accommodate the demands of a growing population, and the impacts of climate change on food security will need to be minimised (FAO 2009). Identifying opportunities and threats, and developing adaptation options in response to climate change impacts in the marine realm, is essential for optimising the benefits that society can continue to derive from the goods and services provided by marine resources.
