The reader-centredness of translated HIV/AIDS texts into isiXhosa

Mabeqa, Thokozile Valencia 04 1900 (has links)
Thesis (M.Phil.)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: HIV/AIDS is a disease that affects millions of people in South Africa. Various strategies have been implemented to try and curb this epidemic. One of the strategies 'used is the dissemination of information pertaining to the prevention of contracting HIV/AIDS. One of the measures of disseminating such information is through pamphlets and brochures in all eleven official languages of South Africa. This research endeavours to establish whether translated HIV/AIDS brochures are communicative towards its target readers or not. The aim of producing these brochures is to educate people about ways to prevent the spread of HIV/AIDS. On investigating translated Xhosa HIV/AIDS brochures, the researcher established that some brochures are poorly translated and fail to accomplish their purpose. Various factors contribute to the non-communicativeness of these brochures towards their intended target readers. The microstructure as well as the macrostructure of the texts tend to be problematic as far as understanding and reader-friendliness are concerned. In the end the people for whom these texts are intended do not understand the information they so desperately need. The skopos theory has been recommended by functionalist scholars as an appropriate translation approach, as it considers the culture of the target readers as well as the intention of the text. It is also concerned with whether target readers actually understand the target text. Therefore the skopos theory is promoted in this thesis for the translation of informative and instructive medical brochures and pamphlets, especially those translated into Xhosa. / AFRIKAANSE OPSOMMING: MIV/VIGS is 'n toestand wat miljoene mense in Suid-Afrika affekteer. Verskeie strategieë is reeds geïmplementeer om hierdie epidemie te probeer beheer. Een hiervan is die verspreiding van inligting met betrekking tot die voorkoming van MIVNIGS. Inligting oor die voorkoms en beheer van MIV/VIGs word, onder andere, versprei deur middel van pamflette en brosjures in al elf amptelike tale van Suid-Afrika. Hierdie navorsing probeer vasstelof vertaalde MIVNIGS brosjures effektief met hul teikenlesers kommunikeer. Die doel van hierdie brosjures is om mense op te voed oor maniere om die verspreiding van MIVNIGS te bekamp. Deur 'n studie te maak van vertaalde Xhosa MIVNIGS brosjures, het die navorser die slotsom bereik dat sommige brosjures baie swak vertaal word en daarom nie hul doel bereik nie. Verskeie faktore dra by tot die gebrekkige kommunikasie tussen vertalers van hierdie brosjures en hul teikenlesers. Die mikro- sowel as die makrostruktuur van die tekste skep probleme met betrekking tot begrip en lesersvriendelikheid. Uiteindelik kry die persone wat die inligting desperaat benodig, nie toegang daartoe nie. Die skoposteorie word as die aangewese benadering aanbeveel deur kenners van die funksionalistiese vertaalteorie, aangesien dit die kultuur van die teikenlesers sowel as die doel van die teks in ag neem. Hierdie benadering het ook ten doel dat die teikenlesers werklik die teks sal begryp. Die skoposteorie word dus in hierdie tesis voorgehou as die geskikte benadering vir die vertaling van informatiewe en instruktiewe mediese brosjures en pamflette, veral in Xhosa.

Disabled persons : predictors for the risk of contracting HIV/AIDS and primary prevention strategies

Mouton, Jeannie 12 1900 (has links)
On t.p.: Master of Arts (Clinical Psychology) / Thesis (MA)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: Progress has been made in the approach to combating the spread of HIV/AIDS with regards to the Department of Health's presentation of the HIV/AIDS/STD Strategic Plan for South Africa. However, deep concem exists with regards to specific marginalized groups such as disabled persons within the South African sector threatened by the spread of HIV/AIDS. The aim of this paper was to review published academic papers on the specific ways in which disabled people are at risk for contracting HIV/AIDS, and the existence of primary prevention programmes designed and specifically aimed at the disability sector. The roles of non-governmental and other organisations were also looked at. The first section of the review focused on high-risk behaviour among disabled persons for contracting HIV/AIDS. Existing literature covered mainly areas of intellectual disability and psychiatric disability. Disabled persons struggle with the same issues of good education, workers' rights, gender equality, health care and social support and well-being as the general population. These issues are however exacerbated by struggles unique to those living with a disability. Inadequate public and social support increase disabled people's vulnerability to issues such as poverty, lack of resources, and inadequate education, heightening their risk of contracting HIV/AIDS. The second section of the review discusses the area of primary prevention, explaining why prevention programmes should be tailormade for specific needs such as those of disabled persons. Examples of prevention programmes from the literature are looked at, as well as a prevention initiative launched in South Africa. / AFRIKAANSE OPSOMMING: Vooruitgang is gemaak op die gebied van die voorkoming van die verspreiding van MIVNIGS met die bekendstelling van die Departement van Gesondheid se MIVNIGS/STD Strategiese Plan vir Suid-Afrika. Daar is wel steeds kommer oor spesifieke gemarginaliseerde groepe, soos gestremde persone, binne die Suid- Afrikaanse sektor wat bedreig word deur die verspreiding van MIVNIGS. Die doel van die studie was om 'n oorsig te kry van akademiese materiaal wat gepubliseer is oor die spesifieke wyses waarop mense met 'n gestremdheid in gevaar verkeer om MIVNIGS op te doen, asook primêre voorkomingsprogramme wat spesifiek ontwerp en gemik is op die gestremde sektor. Daar is ook gekyk na die rol van nie-regerings- en ander organisasies. Die eerste deel van die studie fokus op hoë risiko gedrag van gestremde persone wat hulle in gevaar mag stel vir die opdoen van MIVNIGS. Bestaande literatuur handel meestaloor die areas van intellektuele gestremdheid en psigiatriese siektes. Gestremde persone moet dieselfde uitdagings oorkom as diegene in die algemene populasie, soos byvoorbeeld die gebrek aan goeie onderwys, arbeidsregte, diskriminasie op grond van geslag, gesondheidssorg, asook sosiale steun en algemene welsyn. Gestremde persone se kwessies word egter vererger deur sekere uitdagings wat uniek is aan 'n lewe met 'n gestremdheid. Gestremde persone ontvang meestalonvoldoende publieke en sosiale steun wat dikwels armoede, gebrek aan hulpbronne en onvoldoende opvoeding tot gevolg het. Laasgenoemde verhoog gestremde persone se kanse om MIVNIGS op te doen. Die tweede deel van die studie bespreek primêre voorkomingsprogramme en waarom dit noodsaaklik is om voorkomingsprogramme te ontwerp wat uitsluitlik gemik is op spesifieke populasies. Daar word dan ook gekyk na voorbeelde van primêre voorkomingsprogramme in die literatuur, asook 'n voorkomingsinisiatief wat in Suid-Afrika geloods is.

SURVIVING SURVIVAL: A THEORY OF LIVING WITH THE THREAT OF AIDS (IMMUNE DEFICIENCY).

DUFFY, PAM REID. January 1987 (has links)
The purpose of this study was to generate a grounded theory explaining the social and psychological processes employed by gay men in living with the threat of Acquired Immunodeficiency Syndrome (AIDS). As members of the high risk group for AIDS, gay men are living with a prolonged threat of unprecedented complexity which has unknown demands on health. An exhaustive preliminary literature review revealed a dearth of theoretical or empirical data addressing this problem. Theory discovery was accomplished using the grounded theory methodology. Two major data collection procedures were utilized: The conduct of increasingly structured interviews of healthy gay men, and an ongoing, progressive literature and media search. Data were sampled theoretically, as guided by the emergent theory. The constant comparative method of analytic induction was used for the analysis of data, in order to identify the elements and structure of the theory. Multiple procedures were incorporated into the analysis to ensure its trackability and credibility. A basic social process, Surviving Survival, was identified as the core category of the theory. Surviving Survival is the continuous process used by gay men to ensure mortal survival as well as outlive the extremity of the AIDS threat. The process is comprised of three subcategories: Vigilance, Safeguarding, and Balancing. The subcategory of Vigilance explains the work of monitoring the threat of AIDS and has both personal and social components. Safeguarding explains the behavior of protecting self and others from the AIDS threat, including AIDS' eventuality. The subcategory of Safeguarding contains Safer Sex, Reassuring Others, and Forecasting. The subcategory of Balancing explains efforts to conserve energy required to sustain affirmation of life and living in spite of the AIDS threat. In continuous interaction, the subcategories of Surviving Survival are interwoven into multiple aspects of gay living. This theory explains the profound impact AIDS has on the mental health of gay men, who both survive and perceive the extremity of the AIDS threat on a daily basis. These findings provide a knowledge base for the nursing discipline in becoming an informed and informing resource for the men who are outliving the threat of AIDS.

A study to explore the factors influencing a female students ability to adopt safe sexual practice at a university in Southern China.

Rosling, Lesley Elizabeth Annette January 2005 (has links)
There are estimated to be 840,000 people living with HIV in China (1) of whom 65% are estimated to be in the 16-29 year age group. Since the end of the Cultural Revolution and the opening of China to Western influence, traditional cultural norms have rapidly eroded and China is described as being in the middle of a sexual revolution (2). People are increasingly engaging in behaviours exposing them to the risk of contracting HIV which is spreading from the traditionally high risk populations to the general population via the heterosexual route (3). Comprehensive prevention strategies are necessary to prevent further spread (4). There is evidence that the observed increase in sexual activity is not accompanied by adequate knowledge of HIV transmission. 79% of 18-25 year olds know that HIV/AIDS can be transmitted by sexual intercourse, but a mere 30% know that correct and consistent condom use can protect against HIV transmission (5).<br /> <br /> This exploratory study investigated the factors that influence safe sexual practices amongst female Chinese university students, enabling or preventing them from taking responsibility for their reproductive health. The literature search revealed this to be a largely unexplored area. The study was undertaken amongst third year male and female students, recruited from the Department of Comparative Literature and Media Studies at the Zhongshan University in Guangzhou, China. Data was predominantly collected using two male and two female focus group discussions. Three key informant interviews supported and contextualised the findings. The study revealed that the factors influencing female students&rsquo / ability to adopt safe sexual practices are complex. The recognised shortcomings of sex education in China (6) are compounded by the taboo of sex and the pressure placed on students for the achievement of good grades.<br /> <br /> The university environment exerts a powerful influence. The ease with which mutually beneficial same sex friendships develop in the dormitory can be contrasted with the difficulties faced by couples attempting to conduct relationships. The restrictive university environment has the effect of driving relationships underground. Gender roles are deeply entrenched. The need to conform to the ideal pure, na&iuml / ve, and non-inquiring female stereotype affects a female student&rsquo / s ability to source sexual health information, negotiate safe sex, and to adopt safe sexual practices. Two distinct male stereotypes emerged: the traditional more gender equal male, and the liberal male who believes in an earlier age of sexual initiation and condones multiple sexual partners. All students are aware of HIV but have misconceptions about the specifics of HIV transmission, believing that HIV can be transmitted by kissing, from unclean baths and from doctors. Some students were of the belief that poor personal hygiene is an indicator of possible HIV positive status. Students were confused by condom quality issues. As they had received no formal condom training students relied on reading the package instructions or working it out for themselves.<br /> This small exploratory study resulted in the production of rich and surprising findings. These are incorporated into recommendations for future research and a comprehensive sex education programme at the university. Abstinence and mutual monogamy should be emphasised. Gender stereotypes that influence behaviour and choice of sex education materials should be acknowledged. Negotiation skills training should be incorporated together with condom and contraceptive advice. A sexual health page on the student website and a training programme for students to become peer-to-peer sex educators should be introduced.

The leadership role of principals in managing HIV and AIDS at schools of the Western Cape Education Department.

Rayners, Sharlene January 2006 (has links)
<p>The HIV and AIDS epidemic is deemed the single greatest threat to South Africa's future and its growth in one of the most rapid in the world. The South African government has marked 2006 as the year of accelerated HIV and AIDS prevention. It was against this background that the leadership role of principals was articulated as the focus of this research. This study was aimed at gaining an understanding of the challenges facing school principals and of the unique role they could play in addressing the HIV and AIDS epidemic.</p>

Transforming masculinities into an asset for HIV prevention : a case study of how Mabutho's (The UCCSA men's organization) teachings on masculinities can mediate HIV prevention in the UCCSA-Mozambique.

Macule, Salvador Armando. January 2012 (has links)
This study explores whether and how Mabutho’s (The UCCSA men’s organization) teachings on masculinities can mediate HIV prevention in the Mozambique Synod of the United Congregational Church of Southern Africa (UCCSA). It begins by showing the importance of Mabutho in church and society in order to establish whether this male-dominated Christian organization can play a role in HIV prevention. The study is premised on the growing literature which suggests that organized religion (especially Christianity and Islam)*[¹], which are the main religious institutions in the world, and in Africa in particular, have been the birth place for the patriarchal ideologies which are critical in the promotion of the HIV pandemic. Through a close analysis of Mabutho’s teachings, the study will show that though most of Mabutho’s teachings are sustained by a patriarchal ethos, Mabutho have agency, and can be an asset in the prevention of the HIV pandemic. It further argues that Mabutho, just like other men’s organizations which play a pivotal role in the life of many churches, can be used as a space for the liberation of harmful notions of masculinities in the era of the HIV pandemic. The study concludes by recommending that the UCCSA in Mozambique improve in the pre- and post-marital teachings on marriage and sexuality. *[¹] See Manda, D.

The impact of HIV/AIDS on children in Swaziland : opportunities for, and constraints on, scaling up interventions

Jones, Lynne January 2007 (has links)
This research focuses on vulnerable children in Swaziland, the country with the highest level of adult HIV prevalence in the world, where nearly 25 percent of children will be orphaned by 2010. It investigates the experiences of relatively poor urban children growing up in the epidemic and the coping strategies the children and their adult carers adopt. Through the lens of both children and adult carers, it explores the ways sexual knowledge is gained and used by older children in the context of HIV/AIDS as well as the experience of coping with widespread bereavement. In this way, it adds to the literature on childhoods in the 'South' and the increasing recognition of the heterogeneity of children's lived experiences. Rather than being seen as passive, the agency of both vulnerable children and their adult carers emerges as they seek to improve their livelihoods. The way this agency connects with government, NGO and community structures is revealed by showing the opportunities for and constraints on gaining access to education and health-care. The interwoven roles of government, international donors, NGOs and civil society is explored by assessing the relative merits of supporting vulnerable children by either welfare assistance to poor families or new forms of 'community' care structures or institutionalised residential care. The critical importance of relationships and power relations between key actors in different organisations and the effect this has on implementation of interventions for children is discussed as well as the relevance of these findings to vulnerable children in other settings.

Screening and phytochemical characterization of a South African herbal concoction for anti-HIV-1 activity

Hlatshwayo, Vincent Nkosinathi January 2017 (has links)
A dissertation submitted to the Faculty of Science under the School of Molecular and Cell Biology, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master in Science. Johannesburg, June 2017. / In South Africa, the anti-HIV-1 activity of various indigenous plants has not been studied extensively. Most of the phytochemical screening work has focused on anti-cancer activity with less attention given to infectious diseases. A large proportion of South Africans (70-80%) still rely on traditional medicines for treatment of various ailments. And, therefore, there is a need to evaluate and validate the effectiveness of the traditional medicines. The aim of this study was to identify, screen, phytochemically characterize and isolate bioactive compounds from a South African herbal extract that exhibit the best anti-HIV-1 activity. Three extracts were prepared: an ethanol extract, a dereplicated ethanol extract and an aqueous extract from a herbal concoction comprised of a mixture of six plants. These herbal concoctions were investigated for anti-HIV-1 subtype C activity. Phytochemical profiling of the ethanol- and dereplicated ethanol- extracts from the herbal concoctions showed the presence of intermediate polar compounds (flavonoids, alkaloids, sugars and terpenes) for both extracts, while the aqueous extract contained predominantly highly polar compounds. Anti-HIV-1 screening of the three extracts showed that the ethanol and dereplicated ethanol herbal- extracts had the best anti-reverse transcriptase activity. The ethanol extract had mean IC50 values of 56.53, 53.96 and 55.39 μg/ml against MJ4, Du179 and CM9 HIV-1 subtypes C isolates, respectively. The dereplicated ethanol extract had mean IC50 values of 51.87, 47.56 and 52.81 μg/ml against MJ4, Du179 and CM9 HIV-1 isolates, respectively. The aqueous extract was inactive against HIV-1 activity. Moreover, both the ethanol- and dereplicated ethanol- extracts showed activity against HIV neutralization. The ethanol- and dereplicated ethanol- extracts had mean IC50 values of 36.33 and 32.06 μg/ml, respectively. Furthermore, they also potently neutralized Vesicular stomatitis virus (VSV) yielding mean IC50 values of 24.91 and 20.82 μg/ml for ethanol- and dereplicated ethanol- extracts, respectively. All extracts were inactive against Murine leukemia virus (MLV). The isolation and phytochemical characterization of the bioactive compound(s) was done by utilizing various chromatographic and spectroscopic methods. Four homoisoflavanoids were isolated and tested for anti-HIV-1 subtype C activity. Three compounds (1, 3a and 3b) were inactive while compound 2 was found to be bioactive against HIV-1 reverse transcriptase (RT) and yielded mean IC50 values of 7.23 ± 1.88, 12.83 ± 0.41 & 12.81 ± 0.10 μg/ml for MJ4, CM9 and Du179 HIV-1 subtype C isolates, respectively. Compound 2 had a mean CC50 value of 23.08 ± 0.1981 μg/ml against HEK293T cells. Overall, the data suggested that ethanol- and dereplicated ethanol- herbal extracts possess direct and indirect anti-HIV-1 activity. They possess a cocktail of phytochemicals that can inhibit HIV-1 RT, HIV-1 entry. Furthermore, these extracts possess phytochemicals that can lower the activation of inflammatory responses during an infection and, hence, reduction in the number new cells infected during the course of HIV-1 infection. Moreover, they possess phytochemicals that have antioxidant activity which, in relation to HIV infection, results in a boosted immune system response in order to ward off the virus. / MT 2017

HIV-1 subtype C proteases: overexpression, structural, kinetic and thermodynamic characterisation

Tomescu, Mihai-Silviu 10 May 2016 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2016 / According to UNAIDS, there are ~36.9 million people infected with HIV-1 in the world. Of those, 25.8 million live in sub-Saharan Africa and 6.8 million in South Africa. HIV-1 subtype C accounts for over 95% of HIV infections in South Africa. HIV-1 retrovirus acquires mutations rapidly because of the viral reverse transcriptase. Naturally occurring polymorphisms distinguishing wild type C-SA PR from other proteases make it less susceptible to inhibitors. E35D↑G↑S is a C-SA PR variant with a double insertion in the flap region of the protease. The insertions and background mutations may decrease susceptibility to inhibitors as well as alter kinetic parameters due to increased flap flexibility. This study intended to characterise the effect of the mutations and insertions in E35D↑G↑S on structural, kinetic activity and drug susceptibility. Chemically-synthesised E35D↑G↑S autocatalyses rapidly, impeding further characterisation. There was no detectable overexpression of the E35D↑G↑S protease in Escherichia coli BL21 (DE3)pLysS and Rosetta 2® cells. If the protease is catalytically enhanced, attributed cytotoxicity may prevent overexpression of the protein. Increased autocatalytic activity could also prevent crystallisation. Inactive E35D↑G↑S D25A did not overexpress either, indicating that codon harmonisation with the expression host ought to be performed. C-SA PR was shown to be a predominantly beta-sheeted protein using circular dichroism spectroscopy. The KM of the fluorogenic substrate resembling the capsid/ p2 cleavage site for C-SA PR was 22.02 ±4.09 μM. The specific activity, catalytic turnover and catalytic efficiency of the wild-type C-SA PR protease were found to be 35.68 ±1.06 μmole.min-1.mg-1, 12.79 ±0.38 s-1 and 1.17 ±0.055 s-1.μM-1, respectively. The thermodynamics of binding of atazanavir, ritonavir and darunavir to C-SA PR were determined using isothermal titration calorimetry. The binding of atazanavir and ritonavir to C-SA PR is entropically driven and enthalpically opposed. However, the binding of darunavir to C-SA PR was found to be both entropically and enthalpically favourable. The dissociation constants of the inhibitors in the absence of substrate (Kd) are in the pico-molar range and increased by approximately one order of magnitude when saturating concentrations of substrate were introduced. Atazanavir, ritonavir and darunavir have dissociation constants (Kd) of 160.56 ±54.59 pM, 113.34 ±46.47 pM and 10.24 ±6.02 pM, respectively. Darunavir binds significantly tighter. Keywords: C-SA PR, E35D↑G↑S, insertion mutations, protease, autocatalysis, ITC.

The effect of a peer education programme on peer educators of the HIV/AIDS unit of the Cape Peninsula University of Technology (CPUT)

Kalunga, Moto Jean Bosco January 2016 (has links)
Thesis (MTech (Environmental Health and Occupational Studies))--Cape Peninsula University of Technology, 2016 / Currently, the world faces many challenges such as a food shortages, fossil fuel depletion, floods, earthquakes, recession, wars, and climate change. It also faces diseases such as Human Immune Deficiency Virus /Acquired Immune Deficiency Syndrome /Sexually Transmitted Infections and Tuberculosis (HIV/AIDS /STI and TB). This study focused on HIV/AIDS/STI and TB, and the impact of changes in sexual behaviours of student peer educators as a result of peer education programmes offered by the HIV/AIDS Unit at the Cape Peninsula University of Technology (CPUT). Although young people today have a better understanding of risky sexual behaviours, HIV remains a health problem among the youth in South Africa. HIV/AIDS is a disease that affects all sectors of the population- rich and poor, young and adult, educated and uneducated. Tertiary institutions are places where many young female and male students live independently, unsupervised by their parents or guardians, in either private accommodation or student residences. Under these circumstances it may be expected that some students will explore and experience intimacy in their relationships. Hence, universities could play a vital role in shaping students’ attitudes and behaviours towards relationships, safer practices, and respect for others. Given the current absence of a cure or vaccine for HIV/AIDS, peer education should appear as an important tool in HIV prevention strategy. It draws on several well-known behavioural theories and many researchers view peer education as an effective behavioural change strategy. A formal structured Peer Education Programme was initiated and implemented at the HIV/AIDS Unit at Cape Peninsula University of Technology (CPUT) since 2004. This initiative was in line with one of the twelve strategic objectives of the HIV/AIDS Unit at the CPUT. This study therefore, aimed to assess the reflexive effect that the Peer Education Programme had on student peer educators who volunteer their services at the HIV/AIDS Unit at CPUT. It further attempted to assess the effect of the Peer Education Programme on changes in sexual behaviours that could occur amongst student peer educators. The purpose of this programme was to explore peer educators who were based in the HIV/AIDS Unit applying their acquired knowledge and skills; so that they may become role models for their peers by practising what they taught, and not taught what they proposed to practice. The study furthermore, forms on how effective the Peer Education Programme of CPUT’s HIV/AIDS Unit is in changing sexual behaviours of the student peer educators.
