Item Risk factors associated with HSV-2 sero-prevalence and, the level of symptom recognition among women in inner city Johannesburg - implications for public health interventions(2009-11-13T14:13:48Z) Mlaba, Nonkululeko ZamaximbaBackground: Herpes Simplex Virus type 2 (HSV-2) is a common cause of genital ulcers worldwide and has emerged as a co-factor in human immunodeficiency virus (HIV) acquisition and transmission. A study was conducted to determine the prevalence of HSV-2, its correlates, the accuracy of reported history of genital ulcer disease (GUD) to predict HSV-2 infection and the extent of symptom recognition in a clinic population in Johannesburg. Methods: 210 women aged 18 years or older were interviewed and socio-demographic, sexual behaviour and clinical information collected. Serological testing for HSV-2 and HIV infections was performed, but only where sera were available for the latter. Factors associations with HSV-2 infection were assessed using logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI). The sensitivity, specificity, predictive values and likelihood ratios of a history of GUD were calculated. Results: The estimated sero prevalence of HSV-2 was 73% (95% CI 67% - 79%). Few participants, 13/206 (6%) participants had knowledge of genital herpes. Only 9/203 (4%) participants recognised lesions of genital herpes following education and counselling about HSV-2 infection. HSV-2 infection was associated with older age(>25 years of age) OR 2.6 (95% CI 1.4-5.0), spending more than 2 nights away from home, OR 6.0 (95% CI 1.0-62.7), having more than 2 sexual lifetime partners, OR 2.2 (95% CI 1.1-3.9), a history of an STI in the past 3 months ,OR 3.6 (95% CI 1.2-9.5) and HIV infection, OR3.3( 95%CI 1.4-7.9). A history of genital ulceration performed poorly as a predictor of HSV-2 seropositivity; the sensitivity was 7% and specificity was 96%. Conclusion: HSV-2 prevalence was high and few participants were aware of their infection. HVS-2 infection was associated with risky sexual behaviour .A history of genital ulcer disease was not sufficient as a diagnostic tool for HSV-2 infection. Public health interventions should focus on behavioural modification and increasing awareness of genital herpes. HSV-2 management should be incorporated into HIV care and STI protocols.Item Cities of refuge: the emergence of temporal urbanism(2009-09-21T11:35:08Z) Leong, TerenceIn the era of globalisation we are required to negotiate a large series of global flows. These include the flow of capital ideas, imagery, goods and people. Contemporary culture has increasingly become nomadic, and the idea of place has become transitive. This condition stands in contradiction to the time-honoured notion of the city as a stable entity. Whether brought about by natural catastrophe or initiated by choice, instant cities emerge, only to disappear again just as rapidly. This has given rise to new terms such as relief urbanism, deadline urbanism or event urbanism. This shift from notions of fixed locality to temporary accommodation for mass migration requires equivalent forms of flexibility in planning. (Weiss 2007:3) This thesis will focus on the particular flow within this contemporary situation which has the biggest implication for architecture, namely the movement of people. Since the world war, migrancy has rapidly become more global in scope and scale with there being more mobility than any other period in history. (Cairns 2004:3) Contemporary migrancy involves the movement of immigrants, emigrants, guest workers, refugees and asylum seekers. The effects of migrancy are also being more intensely felt and widespread than ever before. Nowhere are the impacts more evident than in Africa where the movement of people as a result of war, poverty and persecution are central to the continent’s economics and politics. While migrancy is rapidly transforming Africa the region lacks the capacity to understand and manage these movements. (Forced Migration Studies Programme 2008) So the focus of this thesis will be on refugees and asylum seekers seeking refuge in South Africa and the impacts it is having on displaced people themselves and the local population made terrifyingly manifest in the recent Xenophobic attacks plaguing the country. Following a discussion of the many problems faced by refugees and the root causes of the Xenophobic attacks in Johannesburg this thesis will look at the alleviation of some of these problems culminating in the design of a Prefabricated Housing Prototype and System which can be implemented in a combination of contexts. The system will be developed using 3 test studies. The first will be as an infill project in an dense urban context providing cheap rental unit options for the urban poor including South African low income earners and refugees in the inner city, the second will be a housing model for upgrading stable South African informal settlements and the third as an alternative Refugee camp in an emergency or cross border context. It will examine the role of architecture as a means to sustain dignity and create a sense of belonging for people with very few social connections. The facility will aim to help people regain control of their lives by helping them to contribute to the market economy. It will also aim to be an architecture that is against alienation and will facilitate healing.Item Inner-city ritual centre: reflect + facilitate culture(2009-09-21T09:02:24Z) Mavunga, TatendaThe built environment is a product of man’s rationales and understandings of space. It is on the basis of these understandings that man builds, to facilitate his ways of life. These “understandings”, are the discourses that each individual is born into and the “ways of life” are the cultural practices resulting from these discourses. Architecture being a product of cultural discourse is intended to facilitate cultural practices. Post 1994 South Africa, has inherited a Johannesburg inner-city built environment, which is predominantly a product of apartheid and colonial discourse. During this era, black people were marginalised and excluded from the inner city, both physically and through architectural representation. The inner city was built in accordance with western (white) discourse to facilitate western cultural practices. Today the inner city is predominantly inhabited by black people, who were excluded and marginalised in its conception. Post colonial theorists assert that, while black people have embraced “modernity” and “western urbanity”, it has not resulted in a complete acceptance or appropriation of western cultural practices and discourses. Due a process termed “post colonial hybridity” these people merge the two seemingly irreconcilable cultural discourses and practices to form new cultural hybrids. The consequence of hybridity in the inner-city is; while the appropriated western cultural practices and discourses are inherently reflected and catered for, the retained aspects of black cultural practice and discourse remain marginalised. The built environment, which is meant to facilitate and reflect, negates and marginalises aspects of black discourses and cultural practices. “To be truly expressive, a building should grow out of its natural, social, and civilization context. It should reflect not only the personal values, needs and interests of its dwellers but also its relation to its natural and architectural site. Thus the formal organization of a building cannot be imposed on a people from the outside; it should originate from the context of human life in the given region. In this origination the process of spatial articulation results from a thought- full grasp of the dynamic interaction between the material elements of the architectural work and the human vision which guides this activity.” (Mitias 1994:103) In order to make a contribution to the creation of a more inclusive built environment this paper proposes the development of a hybrid building prototype that would facilitate and reflect the hybrid cultural practices and discourses of the city’s black inhabitants. The building prototype named the “Inner City Ritual Centre” aims to facilitate some of the marginalised practices of black people living in the city and to reflect some of the excluded spatial understandings of black people. The paper proposes a method of practice that utilises postcolonial hybridity, to include excluded and marginalised practices and discourses into the architectural representation of the city. This paper uncovers and highlights a few of these discourses and practices and demonstrates how the use of postcolonial hybridity in architecture would result in a more inclusive built environment.Item Reclaiming the city: housing for inner-city Johannesburg(2009-09-16T10:03:07Z) Harrison, MariannaThe way in which a city is spatially laid out effects the natural environment of the planet (for example: pollution and the depletion of natural resources) as well as the social environment (the community and daily life) of its residents. Through the exploration of various modern urban planning theories, I will begin to look at some different approaches to urban planning. This document favours the compact city approach which advocates higher densities, mixed use development, public transport and community living. This approach relates to initiatives currently underway in the inner city of Johannesburg. This document is about the exploration of how people live in the city and the issues surrounding housing in the urban context. The proposed architectural project is a housing scheme located in Newtown, Johannesburg. Central concepts include: urban regeneration, inner city living, visual variety in the urban realm, street edge conditions and public to private hierarchiesItem Chaos and order: transport interchange / link(2009-09-16T06:17:21Z) Bhengu, Nkululeko ThabaniNo abstractItem Item Item Item Item
