<p>The privatization of public prisons has caused much controversy in South Africa as well as internationally. However, it should be noted that the level of resistance to privatisation within the South African context has been minimal by international standards. It is not clear what might have contributed to this quiet approach given the fact that there are many anti-privatisation campaigns driven by the labour movement and civil society groups in South Africa. This research investigation focused on the privatisation of prisons and prison services in South Africa and has explored the various advantages and disadvantages that exist in this respect.</p>

Community service as an alternative to imprisonment at its inception was taken up very strongly by the judiciary as part of the reform of the criminal justice system in Uganda. The successful enactment of the Community Service Act, Act no: 5/2000, was an achievement towards the implementation of the programme in the country. However, its implementation as an alternative sentence is currently proceeding at a slow pace. The Ugandan law still allows courts to exercise their discretionary powers with regard to either using prison sentences or community service. Courts still seem to prefer to use imprisonment irrespective of the nature of the offence, thus leading to unwarranted government expenditure and prison overcrowding. An additional problem is that some offenders come out of prison having been negatively affected by their interaction with even more serious offenders. This study was undertaken to establish whether community service as an alternative to imprisonment can be effective with regard to reducing recidivism and to accelerating reconciliation and reintegration of minor offenders back into their communities.

This study was designed to determine whether chis-quared based tests for independence give reliable estimates (as compared to the exact values provided by Fisher's exact probabilities test) of the probability of a relationship between the variables in 3 X 3, 3 X 4 , and 3 X 5 contingency tables when the sample size is 10, 20, or 30. In addition to the classical (uncorrected) chi-squared test, four methods for continuity correction were compared to Fisher's exact probabilities test. The four methods were Yates' correction, two corrections attributed to Cochran, and Mantel's correction. The study was modeled after a similar comparison conducted on 2 X 2 contingency tables and published by Michael Haber.

The problem this investigation deals with is how The Echo functions as a communication vehicle within the TDC. Information was gathered through visits, interviews and a questionnaire. Organization is as follows: Chapter I, introduction, Chapter II, history and development; Chapter III, analysis of questionnaire data; Chapter IV, content; Chapter V, summary and conclusions. The study found that The Echo is often the sole source of TDC information to inmates, frequently aids administrators in providing inmates with information, provides an outlet for creativity, and enjoys little censorship. The report concludes that The Echo is an effective information medium, and that future study is possible in the role of the prison press in influencing rehabilitation, its contact with the outside public, and in inmate-produced magazines and journals.

In the present work the vacuum polarization and the circular dichroism of hydrogen-like atoms are studied. We derive equations for the Fourier transforma- tion of the vacuum expectation value of the charge density. We use it to derive Uehling potential and calculate energy shifts caused by it. Then we discuss effects of vacuum polarization in higher orders of α. In second part we define circular dichroism and we express it in terms of reduced matrix elements. Then we derive the formula for parity vilating potential which is generated by weak interaction and together with other results we use it to find the expression for circular dichro- ism in terms of hydrogen radial functions. 1

M.A. / Community corrections or correctional supervision, which falls under the Department of Correctional Services and was established in 1991 in South Africa, serves as an alternative sentence and to cater for people who are on parole. This study aims to explore the effectiveness of a life skills programme at Johannesburg Community Corrections rendered to probationers by social workers. Probationers are people who have been given a sentence of correctional supervision by the court. The probationers are compelled to attend one of the established programmes, for example, life skills programmes, as one of the conditions of their sentence. Community corrections B-Order (1991: 34) states that programmes are directly focused on the typical problem area or behaviour of the probationer and shall be aimed at: • preventing further crime perpetration; • improving general sense of responsibility; • acquiring social skills; • improving family relations; and • preventing alcohol and drug abuse. The aim of this study was to evaluate a life skills workshop presented by Johannesburg Community Corrections to probationers in 2000. A representative sample of twenty respondents who attended a life skills programme from April to May 2000 was used for this study. The findings indicated that the programme addresses the above-mentioned problem areas for probationers. From the findings of the study, it can be concluded that most of the probationers, after being exposed to the programme, show great improvement when it comes to the acquisition of social skills, a general sense of family responsibility, attitude towards crime, and family relations. They are positive about their future and they perceive the wrongs they have done as a learning experience. The research design was both quantitative and qualitative in nature and an interview schedule was completed for the purpose of data collection. The results of this study indicated that the programme is effective. The majority of the respondents stated that after being exposed to the programme, their perception, attitude, thinking and life style had changed. The programme has to be modified, as it does not address entrepreneurial and business management skills. Furthermore, it does not include entrepreneurial skills training, which would ultimately help and assist probationers to gain employment or to be self-employed through training in terms of being self-reliant and self-employed. / Prof. J.B.S.

Nesta dissertação, estudamos implicações geradas pela quebra da simetria de Lorentz na Eletrodinâmica Quântica. Analisamos férmions interagindo com um campo eletromagnético nos contextos da mecânica quântica e ao efetuar correções radiativas. Na mecânica quântica, os termos de quebra da simetria de Lorentz foram tratados como perturbações à equação de Dirac, e seus valores esperados no vácuo foram obtidos. Nas correções radiativas, a quebra da simetria de Lorentz foi introduzida nessa interação para que o termo tipo Chern-Simons pudesse ser induzido em (3+1) dimensões. Também discutimos as consequências geradas por este termo sobre as velocidades de propagação de fótons clássicos. / In this dissertation, we study the implications generated by the Lorentz breaking symmetry in quantum electrodynamics. We analyze fermions interacting with an electromagnetic field in the contexts of quantum mechanics and we make radiative corrections. In quantum mechanics, the terms of the Lorentz breaking symmetry were treated as perturbations to the Dirac equation, and their expected values were obtained in a vacuum. In the radiative corrections, the Lorentz breaking symmetry was introduced in this interaction for the Chern-Simons like term could be induced in (3 +1) dimensions. We also discussed the consequences generated by this term on the propagation speeds of classic photons.
