- Description: Publisher version , In this article we compare and contrast the figure of the migrant, central to Dan Jacobson’s short story ‘A Long Way from London’ ([1953] 1958. A Long Way from London and other stories. London: Weidenfeld & Nicholson), and to Jean Rhys’s short story ‘Let Them Call It Jazz’ ([1962] 1987. The Collected Stories. New York: Norton), both of which are set in London in the early to mid-twentieth century. The main argument is that these figures, as migrants in London from South Africa and the Caribbean respectively, similarly occupy a liminal space despite stark differences in class, race and gender. In both stories this liminal space is described through evocations of London as a hostile diasporic space, lacking in hospitality, and experienced by the migrant figure as a place of confinement and incarceration. Also, both stories utilize the technique of silence or lacunae when it comes to issues of specific discrimination and abuse, such as racism or sexual exploitation. For the purposes of comparison, the character Manwera from ‘A Long Way from London’ and, Selina, the protagonist of ‘Let Them Call It Jazz’, are selected for analysis. Particularly, their respective responses (Manwera’s pride and dignity, and Selina’s recovery after a breakdown, and her musical talent) to the exigencies of migration are suggestive of ‘adaptive strength’ (Steve Vertovec and Robin Cohen [1999] 2001. Migration, Diasporas and Transnationalism. Cheltenham and Northampton MA: Elgar Reference Collection, xviii), a common feature in transnational literature which attempts to celebrate liminality and multiplicity as key characteristics of a transnational subjectivity. In addition, the protagonist of ‘A Long Way from London’, Arthur, offers a contrast to Manwera and Selina, not only because of race and class, but because he is depicted as having adapted to and assimilated into British culture, while being strangely detached from and ambivalent about both homeland and diasporic home. Varying forms of adaptive strength are portrayed in both stories, but they close with intimations of bleak futures for the migrant figures. The essay thus concludes with the observation that in these two stories, the figure of the London migrant is rendered as facing further grave challenges, and that all three figures ‘belong nowhere’ (Rhys [1962] 1987 Rhys, Jean. [1962] 1987. The Collected Stories. New York: Norton. [Google Scholar] , 175).

- Description: publisher version , The rapid expansion of social protection in the South provides a rich diversity of experiences and lessons on how best to reduce poverty and ultimately eradicate it. Knowledge on how best to ‘grow’ social assistance, understood as long-term institutions responsible for reducing and preventing poverty, is at a premium. This article examines the expansion of social assistance in Brazil and South Africa, two of the middle income countries widely perceived to have advanced furthest in ‘growing’ social protection. It examines three aspects: the primacy of politics in explaining the expansion of social protection and assistance, the tensions between path-dependence and innovation in terms of institutions and practices, and the poverty and inequality outcomes of social assistance expansion. The article concludes by drawing the main lessons for other developing countries.

‘Gender’ and constructions of spousal mourning among the AmaXhosa in the Eastern Cape

- Description: Among the AmaXhosa the death of a person is marked by a tradition called ukuzila - the equivalent of the mourning process. As a sign of spousal mourning, and to show respect, the remaining spouse has to put on a marker (be visible). However, it is mostly the woman who is under obligation to show her mourner status by wearing ‘clothes of mourning’. The discriminatory nature of the practice, especially pertaining to visibility and some of the detrimental effects on the widows’ health and safety have been documented by some researchers, but the reasons for the continuity of visibility remain largely unexplored. Taking into account the dynamic nature of ‘culture’, this research explored the discourses deployed in men and women’s constructions of ukuzila specifically focusing on spousal mourning and the continuity of widows’ visibility in spite of their resistance to it. The research used postcolonial feminism drawing on postructuralism as its theoretical lens. This theoretical lens provided useful concepts such as hybridity, visibility, surveillance and power with which to examine spousal mourning and conceptualised people’s subject positions as multiple, fluid and contingent. Furthermore, the research employed thematic and discourse analysis at its methodology. Discourse analysis was employed to identify and analyse the discourses utilised in the constructions of spousal mourning. The research was conducted through focus group discussions held with younger and older urban and rural men and women, as well as interviews held with widows and widowers and key cultural informants. Concerning the question of constructions of spousal mourning for men and women, visibility of the mourner emerged as a central and contentious issue. Some participants were of the view that one could show mourning by engaging in culturally appropriate mourning behaviour, whilst others were of the view that showing one’s mourning had to be visible by publicly displaying mourning through a marker. Another group proposed mourning “by heart”, whereby the mourners’ status could either be inferred from their behaviour, whereas others maintained that behaviour was not mandatory. Various justifications for the continued visibility of widows were advanced. These justifications included showing love and respect to the deceased husband; showing respect to the ancestors; and helping to monitor their own behaviour in order to ensure that it is in line with appropriate mourning behaviour. The continued visibility of widows was also used to regulate the widows’ sexuality. Widows were coerced to put on ‘clothes of mourning’ in order to ‘protect’ them from being approached by men for a relationship during the mourning period. The regulation of the movement of widows was also managed through visibility. Widows’ movements were restricted in order to protect the community from pollution or bad luck. For example, they were not allowed to visit places of entertainment or visit other households. Key discourses identified were the familial-‘ukwenda’, respect-‘hlonipha’, and male sexual drive (MSD) discourse. The familial - ‘ukwenda’ discourse is centred on the idea that one is ‘married to the household’, which includes the nuclear family and wider extended family including ancestors. According to the respect-‘hlonipha’ discourse, respect is due to others on the basis of their age, status, and more especially their gender. Showing respect (hlonipha) necessitates the avoidance of all forms of behaviour and utterances that could be deemed disrespectful. The MSD holds a widespread view of sexuality as a biological drive that resides within each male and it was drawn on to make sense of discontinued visibility among widowers, whilst visibility of widows continued. It is argued that it is these discourses, embedded in the ‘culture’ of the AmaXhosa and upheld by the family that sustain the discriminatory nature of the practice, especially concerning the continued visibility of widows in spite of the resistance that has been voiced.

- Description: This article examines the practical adequacy of the recent defining of a normative framework for the South African National Curriculum Statement that focuses on the relationship between human rights, social justice and a healthy environment. This politically framed and socially critical normative framework has developed in response to socio-political and socio-ecological histories in postapartheid curriculum transformation processes. The article critically considers the process of working with a normative framework in the defining of environmental education teaching and learning interactions, and seeks not only to explore the policy discourse critically, but also to explore what it is about the world that makes it work in different ways. Drawing on Sayer’s perspectives on the possibilities of enabling ‘situated universalism’ as a form of normative theory, and case-based data from a teacher professional development programme in the Makana District (where the authors live and work), the article probes the relationship between the establishment of a ‘universalising’ normative framework to guide national curriculum, and situated engagements with this framework in/as democratic process. In this process it questions whether educators should adopt the ‘norms’ as presented by society and simply universalize and implement them as prescribed by curriculum statements, or whether educators should adopt the strategies of postmodernists and reduce normative frameworks to relations of power situated in particular contexts.

- Description: Al Wunder's biography, in his own words: I had four lucky breaks that precipitated my becoming a teacher of improvised movement theatre. Between the ages of eight and fourteen I broke my right leg four different times. In 1962, I began modern dance classes with Alwin Nikolais as a physical therapy. His choreography and improvisation sections of class inspired me to teach and perform professionally. I spent eight years studying, teaching, choreographing, and performing with Nikolais. 1970 saw me move to the San Francisco Bay area where I opened a dance studio teaching Nikolais dance technique and improvisation. In 1971, I joined forces with Terry Sendgraff and Ruth Zaporah creating The Berkeley Dance Theater and Gymnasium. My focus was to create a way to teach dance technique through improvisation. I met my Australian wife, Lynden Nicholls, in 1981 when she came to study Motivity at Terry’s studio in Berkeley. In 1982, I moved to Melbourne, Australia where Lynden and I set up a dance studio. My focus changed from teaching dance technique improvisationally to teaching improvised movement theatre performance

‘Charmer boys’ and ‘cream girls’: children’s construction of the (hetero)sexual self through football and implications for Life Orientation sexuality education

- Description: Due to the adult-centric ‘common-sense’ view of primary school children as non-sexual, research on schooling, gender and sexuality in South Africa rarely addresses primary schools. In contrast, this paper explores how nine-to-ten year-old children in a working-class, township primary school near Durban (hetero)sexualise their gendered identities through football. By illuminating the different ways in which the young children in the study construct themselves as both gendered and sexual beings in their everyday playground and sometimes ‘underground’ cultures at the school, the paper calls into question the ‘common-sense’ discourse of childhood which (re)produces primary schools as sexuallyfree contexts. Findings raise pertinent implications that call for the (re)conceptualisation of children; from being seen simply through the discourse of sexual innocence to being conceptualised as people who are capable of expressing sexual agency. This, in turn, calls for the development of new ways of working with the young children in Life Orientation sexuality and HIV/AIDS education which are empathetic and sympathetic to the children’s own constructions of themselves as both gendered and sexual beings.

- Description: Ritual male circumcision is among the most secretive and sacred of rites practiced by the Xhosa of South Africa. Recently, the alarming rate of death and injury among initiates has led to the spotlight of media attention and government regulation being focused on traditional circumcision. While many of the physical components of the ritual have been little altered by the centuries, its cultural and social meanings have not remained unchanged. This paper attempts to understand how some of these cultural and social meanings have shifted, particularly with respect to attitudes towards sex and the role that circumcision schools traditionally played in the sexual.

- Description: The success of Nigeria’s 2015 general elections was unexpected, given the tense political and security climate in which the polls were conducted. It is against this backdrop that this study explores the contribution of four newspapers (The Guardian, Vanguard, Independent and Leadership) and, in particular, their editorials, to the relatively peaceful and mostly credible 2015 general elections in Nigeria. This qualitative study, located with an interpretivist tradition, draws on both in-depth individual interviews with editorial writers, and thematic content analysis of selected editorials to explore three themes: - violence-free polls, rational voting and credible electoral process. These newspaper editorials made moral and ethical appeals urging “supra-national” and patriotic attitudes as well as more detailed process interventions. Drawing from the theories of argumentation, the research suggests that three kinds (forensic, epideictic and deliberative) of arguments were made and three modes of argumentation (logos, pathos and ethos) were used by editorial writers to advance their arguments. This study examines what the editorial writers hoped to achieve and the normative ideals they drew on in the discharge of what they saw as their editorial duties. Drawing on theoretical insights from normative theories of journalism, and particularly social responsibility theory, this research posits that editorial writers hoped to arrest the spate of violence in the Nigerian polity, raise the level of discussion and redirect the attention of politicians in particular to core issues confronting ordinary Nigerians. The study finds a correlation between the editorials written and the normative ideals embodied in the social responsibility theory, which, the study finds, is the most influential normative ideal in the ‘mainstream’ Nigerian news media, at least in print. This study thus argues that in view of the range and frequency of focus on three core themes, and the persuasive power of writing, a case can be made for the editorials of these four major newspapers playing a constructive and positive role and making some contribution to the eventual peaceful and credible outcome of 2015 national elections in Nigeria.

- Description: This thesis offers an original sociological analysis of regional Non-Governmental Organisations (RNGOs) responding to the HIV epidemic in the Southern African Development Community (SADC) in respect of their emergence, constitution, role, function, embeddedness, accountability and practice of being regional in the HIV response. In doing so, it offers propositions on the conceptualisation of RNGOs and the concept being regional in clarifying regional HIV programming in the context of regionalisation. It also highlights the nexus between regional HIV work, and country and global HIV governance and programming as components of the global architecture of development regime under the tutelage of the United Nations as influenced by the dominant powers. The analysis is based on a hybrid of social systems, actor systems dynamics, institutional and network theoretical analytical frameworks. A triangulation of these frameworks provides a comprehensive grounding on which it is possible to identify and analyse RNGOs as social systems, institutions, actors and nodes that constitute part of the global architecture of the HIV response. This also facilitates the conceptualisation of being regional as both a programmatic typology and state of existence of RNGOs, thus locating these regional actors in the framework of the global HIV governance and programming. It locates them in the resultant web of social relations connecting various development agents in hierarchical and institutionalised structures constructed around HIV governance and responses. Social embeddedness and hence accountability of RNGOs is thus presented as determined by this complex context. Based on an extensive use of organisational documents as well as key informant interviews, the thesis reveals the dominance of funding organisations in determining regional and national HIV programme design and content as well as structuring the organisational practices of RNGOs and other development agents in the HIV response. Because of the demands by donors for accountability on the part of RNGOs for funds received, upward accountability becomes a major preoccupation of RNGOs and becomes privileged compared to downward accountability to their programme beneficiaries. However, RNGOs still enact agency in seeking to manoeuvre their way through the worldwide development system in order to advance the HIV response while also ensuring their own organisational sustainability.

- Description: Why, despite evidence to the contrary, does the narrative of the negative consequences of teenage pregnancy, abortion and childbearing persist? This book outlines a critical view of "teenage pregnancy" and abortion, arguing that the negativity surrounding early reproduction is underpinned by a particular understanding of adolescence. The book traces the invention of "adolescence" and the imaginary wall that the notion of "adolescence" constructs between young people and adults. It examines the entrenched status of "adolescence" within a colonialist discourse that equates development of the individual with the development of civilisation, and the consequent threat of degeneration that is implied in the very notion of "adolescence". Many important issues are explored, such as the ideologies and contradictions contained within the notion of "adolescence"; the invention of teenage pregnancy as a social problem; the construction of abortion as the new social problem; issues of race, culture and tradition in relation to teenage pregnancy; and health service provider practices, specifically in relation to managing risk. In the final chapter, an argument is made for a shift from the signifier "teenage pregnancy" to "unwanted pregnancy". Using data gathered from studies from four continents, this book highlights central issues in the global debate concerning teenage pregnancy. It is suitable for academics, postgraduate and undergraduate students of health psychology, women’s studies, nursing and sociology, as well as practitioners in the fields of youth and social work, medicine and counselling.

- Description: Doreen Baingana’s Tropical Fish explores the migratory experiences of the main narrator-focalizer, Christine Mugisha, as she travels from Uganda to the United States of America. Although the analyses of home, exile, and migration by writers like Edward Said and Paul Tiyambe Zeleza tend to be ungendered; Baingana seems to elaborate on these concerns by reflecting on the gendered experience of travel. As Carole Boyce Davies has argued, the act of travelling and migration opens up new spaces and possibilities for black women writers as they come into contact with multiple places and cultures. In their encounters with migration, black women are able to negotiate and re-negotiate their identities. This article focuses on how Tropical Fish, interrogates complex, contradictory, ambiguous and often conflicted questions of home and migration with their concomitant issues of belonging and alienation/ estrangement and how they are intimately tied to the maternal bond.

- Description: The advancements in virtualization technologies have provided a large spectrum of computational approaches. Dedicated computations can be run on private environments (virtual machines), created within the same computer. Through capable APIs, this functionality is leveraged for the service we wish to implement; a computer power service (CPS). We target peer-to-peer systems for this service, to exploit the potential of aggregating computing resources. The concept of a P2P network is mostly known for its expanded usage in distributed networks for sharing resources like content files or real-time data. This study adds computing power to the list of shared resources by describing a suitable service composition. Taking into account the dynamic nature of the platform, this CPS provision is achieved using a self stabilizing clustering algorithm. So, the resulting system of our research is based around a hierarchical P2P architecture and offers end-to-end consideration of resource provisioning and reliability. We named this system μCloud and characterizes it as a self-provisioning cloud service platform. It is designed, implemented and presented in this dissertation. Eventually, we assessed our work by showing that μCloud succeeds in providing user-centric services using a P2P computing unit. With this, we conclude that our system would be highly beneficial in both small and massively deployed environments. , KMBT_223 , Adobe Acrobat 9.51 Paper Capture Plug-in

β-N-Methylamino-L-Alanine is a developmental neurotoxin

- Description: β-N-methylamino-L-alanine (BMAA) has been implicated in the development of the neurodegenerative diseases Amyotrophic Lateral Sclerosis/Parkinsonism Dementia Complex (ALS/PDC), Amyotrophic Lateral Sclerosis (ALS) and Alzheimer’s Disease (AD), but to date no animal model has adequately substantiated this link at environmentally relevant or even exaggerated BMAA exposure levels. The resulting controversy over a possible role for BMAA in neurodegenerative diseases was further hampered by a lack of evidence for mechanistic explanation for the disease pathology associated with these diseases However, the different responses to BMAA that have been observed in neonatal compared to adult rats, together with the findings of epidemiological studies that exposure to environmental factors in utero or in the early stages of life may be important for the development of ALS several years later, suggested that age of exposure might be the determining factor of BMAA neurotoxicity. This study therefore specifically addresses the developmental nature of BMAA as a neurotoxin, and investigates the pathology and progressive nature of that pathology after exposure to the toxin at the most susceptible age. This study demonstrated the importance of BMAA exposure age over total BMAA dose by showing that the administration of a single neonatal dose of BMAA to rodents on postnatal day (PND) 3, 4 and 5, and not prenatally or on PND 6, 7 and 10, caused behavioural, locomotor, emotional and long-term cognitive deficits, clinical symptoms of neurodegeneration as well as pathological hallmarks of AD, PD and ALS in the central nervous system. Furthermore, the observed behavioural deficits and distribution of neuronal loss and proteinopathies in the rodent central nervous system following exposure to BMAA on PND 3, 4 and 5 (corresponding to the developing age of an infant during the third trimester of pregnancy) is consistent with that typically associated with the disruption of normal dopamine and/or serotonin signaling in the brain and the consequent alteration in normal hippocampal and striatal neurogenesis that is modulated, in part, by dopamine. The pattern of spread and rate of propagation of pathology in this neonatal rat BMAA model provided further evidence that BMAA potentially exerts its effect by acting on neurotransmitter signaling. The observed late onset of typical ALS symptoms and pathology suggest that in this BMAA model AD and/or PD related symptoms develop first, followed by the start of ALS symptoms only after the AD and/or PD neuropathological deficits have severely progressed. This study also demonstrated that BMAA exposure at different doses and at different developmental ages resulted in the development of different combinations of either AD and/or PD and/or ALS pathology and/or symptoms in rats, and it is therefore feasible that in humans the age and/or frequency of exposure as well as the BMAA dose might similarly be a major determinant of the variant of AD, PD and/or ALS that might develop in adulthood. Based on the low BMAA dose that was able to cause AD and/or PD-like neuropathological abnormalities in rats in this study, it is feasible that a pregnant human could over the course of her pregnancy, and specifically during the third trimester of pregnancy, consume sufficient BMAA to result in her unborn child developing AD and/or PD and/or ALS up to 30-50 years later. This neonatal BMAA model is the only non-transgenic rodent model that reproduces the behavioural deficits, neuropathology and clinical symptoms that are typically associated with AD, PD and ALS in humans and that, more importantly, mimics the delayed onset of disease symptoms and typical slow progression of these neurodegenerative diseases with age. It now seems very likely that BMAA is a developmental neurotoxin that, as a result of perinatal, but probably prenatal exposure, causes or contributes significantly to the development of neurodegenerative diseases in humans.
