In this study the nature and extent of the sexual assault and rape of male sentenced offenders and awaiting-trial detainees in Pretoria Local Correctional Centre were investigated. Prison gangs, overcrowding of correctional centres, the involvement of correctional officials and the sexual orientation of the potential victim were highlighted as risk factors in the sexual assault and rape of male offenders and awaiting-trial detainees. As this study focused on both the victim and the offender of male-on-male sexual assault and rape, both victimological and criminological theories were used as a theoretical basis. Creswell’s dominant-less-dominant model of combination was used in this study, with the dominant model being the qualitative methodology, and the less-dominant model the quantitative methodology. Non-purposive sampling was used, as the researcher could not identify the victims and/or perpetrators of male-on-male sexual assault and rape individually. In order to obtain in-depth information on the research participants’ experiences of sexual activities and rape in the correctional centre, face-to-face structured interviews were conducted with one hundred research participants. After the analysis and interpretation of the data, it became evident that male-on-male sexual assault and rape, as well as consensual sexual activities, do occur in this correctional centre. Research participants highlighted four types of sexual engagements in this correctional centre, namely the need for emotional sex, survival sex, compliant sex and forced sexual acts. The reasons offered for the occurrence of rape in this correctional centre include that an agreement had not been reached between inmates and because of that the rape will take place, corruption by correctional officials, the involvement of prison gangs and the use of deception by the perpetrators. Six research participants revealed that they had been the victims of rape. All the victims were raped within days or weeks after their arrival at the correctional centre. Five of the victims did not receive medical treatment after the rape, and none of the victims received counselling or therapy after the rape. Five of the research participants reported that they had sexually assaulted and/or raped other inmates. Four of the perpetrators were awaiting trial for an aggressive offence (armed robbery) and one for a sexual offence (rape). The perpetrators forced their victims to engage in oral sex, inter-femoral sex and anal sex. The aims of the study were reached and recommendations for further research were also made. Emanating from the feedback of the participants as well as the literature review, the researcher developed an Offender Sexual Assault Protocol. The Department of Correctional Services can use this protocol to reduce and manage sexual assault and rape in male correctional facilities. / Thesis (DPhil)--University of Pretoria, 2009. / Social Work and Criminology / unrestricted

Philosophiae Doctor - PhD / Tuberculosis is a bacterial infection which is a major cause of death worldwide. TB is a curable disease, however the bacterium can become resistant to the first line treatment against the disease. This leads to a disease called drug resistant TB that is difficult and expensive to treat. It is well-known that TB disease thrives in communities in overcrowded environments with poor ventilation, weak nutrition, inadequate or inaccessible medical care, etc, such as in some prisons or some refugee camps. In particular, the World Health Organization discovered that a number of prisoners come from socio-economic disadvantaged population where the burden of TB disease may be already high and access to medical care may be limited. In this dissertation we propose compartmental models of systems of differential equations to describe the population dynamics of TB disease under conditions of crowding. Such models can be used to make quantitative projections of TB prevalence and to measure the effect of interventions. Indeed we apply these models to specific regions and for specific purposes. The models are more widely applicable, however in this dissertation we calibrate and apply the models to prison populations.
