- Description: Using the Bondi-Sachs formalism, the problem of a gravitational wave source surrounded by a spherical dust shell is considered. Using linearized perturbation theory, the geometry is found in the regions: in the shell, exterior to the shell, and interior to the shell. It is found that the dust shell causes the gravitational wave to be modified both in magnitude and phase, but without any energy being transferred to or from the dust.

- Description: This working paper covers a survey conducted between 16 and 30 January 1980 of 3 171 black Sub A and Sub B pupils 8 years old or younger, at schools in both the rural and urban areas of the Albany Magisterial District, Eastern Cape. The survey, under the auspices of the Institute of Social and Economic Research (ISER), Rhodes University, was carried out as a result of a request from Dr J. D. Krynauw, Regional Director of Health Services in the Eastern Cape, to assess levels of nutrition of black children. Newspaper reports (see Appendix 1) of low levels of nutrition and high infant mortality rates among young black children in the Eastern Cape appeared to suggest a chronic nutritional situation, a situation not perceived as such by the Department of Health. A comprehensive pilot study was instituted on written request from Dr Krynauw in late October 1979. A report of the pilot study findings was presented in May 1980 to the Department of Health (Fincham, 1980). The present paper elaborates on that report and also includes analyses of data not presented before. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: State control over the labour market usually results in the creation of different categories of labour, each having partial and unequal access to that market. In the Third World, typically, justification for control arises from an over-supply of unskilled rural labour and a small demand for such labour in the wage economy. To reduce massive urban unemployment, the state attempts to control the process of rural-urban migration by, inter alia, manipulating the labour market. ^ In South Africa, the civilised labour policy of the Pact government and the highly sophisticated system of black influx control introduced after the Second World War are two examples of such state control. In these cases, racial categories of labour, having differential access to the labour market, were created. The policy of Coloured Labour Preference is another South African example which is of particular interest since it is applied solely to one region of the Republic. Since 1962, when it was administratively coordinated for the first time, this policy has been applied in the Western Cape, a region comprising the 68 magisterial districts situated south-west of Port Elizabeth, Kimberley and the Orange River. In this region, black work-seekers' access to the labour market is severely curtailed. A series of regulations, particular to the Western Cape, are applied with the object of restricting the number of blacks resident in the region; denying blacks permanent rights of sojourn in the region; restricting the scope of employment for blacks in the region; and favouring coloured above black work-seekers throughout the region. In short, the policy aims to replace black by coloured labour and thereby aims to reduce to a minimum the number of blacks in the region. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

Code of Conduct for Australian companies with interests in the Republic of South Africa

- Description: This is the first report under the voluntary Code of Conduct for Australian companies in South Africa. It marks Australia's entry into an area of monitoring and public reporting where the United States of America, the European Community (particularly the United Kingdom) and Canada have had Codes of Conduct since 1976 to 1978. Each of the countries concerned has companies with investment in South Africa and a physical presence there - through subsidiaries that operate as part of South African industry and that employ South African workers, including black workers. The Codes are intended to secure that companies from outside South Africa do not, when employing non-white (and particularly black) workers in South Africa, exploit the apartheid system. On the contrary, the objective is to work towards the elimination of discrimination at the industrial level - in pay rates, opportunities and otherwise - and at the same time to try to imp rove the position of the employees outside the work place. Those who press for stronger sanctions against South Africa and for active disinvestment policies criticise the Codes as weak palliatives for apartheid. In past years that might have been charged more forcibly. Today the existence of the Codes does not seem to be affecting decisions on sanctions. And the converse also seems to be true; with the sanctions that are presently operating the Codes continue to operate. Of course, when companies do disinvest, the Codes have fewer companies to cover and could eventually wither on that account. To the extent, therefore, that the Codes operate on the fact of foreign companies being in South Africa, they could be thought inconsistent with any policy of rapid disinvestment. However, there are at present no such policies operating at the level of Governments. A question arising from that is whether foreign companies, if they do remain in South Africa, should be subject to Codes and to reports back home as to their conduct, it being recognised that those reports, depending on their content and their reception, may either quieten or stir pressures for further disinvestment.

- Description: The study of local history in South Africa is still in its infancy and has not been accorded the same recognition as elsewhere. There is no convenient manual to guide the would-be local historian of the Cape. There are few models that provide an insight into the main problems encountered by the local historian of a Cape community. In such local histories as exist, attention has been focussed predominantly on the foundation and physical growth of towns, the naming of streets, the establishment of schools and hospitals. Many of these accounts were written for publicity purposes or to commemorate the founding of towns. Although there is no history of the Dutch Reformed Church in Graaff-Reinet, the history of local congregations of the Dutch Reformed Church has generally been well covered in the form of Gedenkboeke and other studies. These frequently have a particular relevance as many towns such as Burgersdorp and Colesberg were founded as a result of the initiative of the church.

- Description: The focus here is upon the 1 169 white men and the twelve white women who were elected or nominated to the South African Parliament in Cape Town between 1910 and the conclusion of the 1970 general and Senate elections.1 Because of the integrated nature of government at the national level in South Africa, an examination of all parliamentarians concurrently produces information on all cabinet ministers during the same period, and for most if not all of the top leaders of the major political parties as well. Hence, recognizing the unitary structure of the South African regime - sometimes expressed in the principle of the 'sovereignty of Parliament' - it seems possible to designate these 1 181 persons as the formally ascendant South African political elite during the country's first six decades. Moreover, there is no reason to doubt that this number includes nearly all of the persons who exercised disproportionately great real power during these years, excepting, of course, those few non-whites who may be thought to have been politically influential at the national level. Every indication is that political life in South Africa centred on these individuals, or at least on some of them, for clearly not all were of equal political importance. Yet even the leaders within this select group, whom we shall also consider separately in detail, frequently (although not in every case) rose to prominence within the institution of Parliament, in part on the basis of their ability to influence and control its deliberations. An understanding of the backgrounds of all parliamentarians thus not only helps to describe the body itself, but may also contribute a new appreciation of the political power of the country's top leadership. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

- Description: The aim of this research is to evaluate the process and impact of outsourcing information technology (IT) services of Eastern Cape Treasury Department (ECTD) to State Information Technology Agency (SITA). This research study has been prompted by the fact that the South African Government through the National Department of Public Service and Administration has established SITA with a sole purpose of improving service delivery by all national, provincial and local government departments. The researcher’s concern is whether the relationship between SITA and these departments is working or not. The research paradigm adopted is a constructivist approach and the ontological position adopted assumed multiple realities. The research method used in this study is the evaluation research method. Key to the research procedure was the fact that four senior officials were interviewed using audio recording, where in two were each chosen from SITA and ECTD. The researcher used document analysis and interviews as a means of collecting data. Separate open-ended questions for SITA and ECTD were structured in such a way that it would be easy to extract themes describing the details of a particular question. The researcher made use of thematic analysis. The theory drive-code development process was key in the research analysis. ECTD outsourced to SITA the following IT services, namely, provision or maintenance of a private telecommunication network (PTN) or a value-added network (VAN); transversal information systems and its data-processing or associated services; training in IT/IS; application software development; maintenance services for IT software or infrastructure; data-processing or associated services for specific IT applications or systems such as website development; and IT support. The interviewed officials from ECTD contend that they used the SCM Guide and SITA ACT when pursuing IT outsourcing for projects such as those listed above. One of the key projects outsourced to SITA is the IFMS, which is a project programme of the National Treasury Department working closely with provinces (e.g. ECTD), National Department of Public Service and Administration (NDPSA) and SITA. The IFMS project has been implemented following the SCM guidelines. The key SCM Guide components are demand, acquisition, logistics, and disposal management. The engagement model used by SITA to guide them on the process of engaging in an IT outsourcing relationship has, according to the officials interviewed, been a success. SITA uses a standard contract wherein other specific contracts receive minor adjustments. The impact of IT outsourcing has shown increases in customer satisfaction improvement, transformation of government procurement and provisioning practices, appointment of Consultants, interpretation of the Preferential Procurement Policy, promotion of the consistent application of Best Practices, information systems security environment, and improving service delivery.

- Description: In July 1987, Eskom gave large wage increases, up to 35% for a general worker. General workers suffered a big fall in the buying power of their wages in the late 1970's but now their wages are higher than ever. The graph shows the buying power, also called "real wages", of wages from 1974 to 1987 for grade 1 and grade 5 workers at Eskom in the group 1 non-shift (national) category.

Prime near-ring modules and their links with the generalised group near-ring

- Description: In view of the facts that the definition of a ring led to the definition of a near- ring, the definition of a ring module led to the definition of a near-ring module, prime rings resulted in investigations with respect to primeness in near-rings, one is naturally inclined to attempt to define the notion of a group near-ring seeing that the group ring had already been defined and investigated into by, interalia, Groenewald in [7] . However, in trying to define the group near-ring along the same lines as the group ring was defined, it was found that the resulting multiplication was, in general, not associative in the near-ring case due to the lack of one distributive property. In 1976, Meldrum [19] achieved success in defining the group near-ring. How- ever, in his definition, only distributively generated near-rings were considered and the distributive generators played a vital role in the construction. In 1989, Le Riche, Meldrum and van der Walt [17], adopted a similar approach to that which led to a successful and fruitful definition of matrix near-rings, and defined the group near-ring in a more general sense. In particular, they defined R[G], the group near-ring of a group G over a near-ring R, as a subnear-ring of M(RG), the near-ring of all mappings of the group RG into itself. More recently, Groenewald and Lee [14], further generalised the definition of R[G] to R[S : M], the generalised semigroup near-ring of a semigroup S over any faithful R-module M. Again, the natural thing to do would be to extend the results obtained for R[G] to R[S : M], and this they achieved with much success.

- Description: This research is the first of its kind to investigate the utilisation of a multi-threading software-based countermeasure to mitigate Side Channel Analysis (SCA) attacks, with a particular focus on the AES-128 cryptographic algorithm. This investigation is novel, as there has not been a software-based countermeasure relying on multi-threading to our knowledge. The research has been tested on the Atmel microcontrollers, as well as a more fully featured system in the form of the popular Raspberry Pi that utilises the ARM7 processor. The main contributions of this research is the introduction of a multi-threading software based countermeasure used to mitigate SCA attacks on both an embedded device and a Raspberry Pi. These threads are comprised of various mathematical operations which are utilised to generate electromagnetic (EM) noise resulting in the obfuscation of the execution of the AES-128 algorithm. A novel EM noise generator known as the FRIES noise generator is implemented to obfuscate data captured in the EM field. FRIES comprises of hiding the execution of AES-128 algorithm within the EM noise generated by the 512 Secure Hash Algorithm (SHA) from the libcrypto++ and OpenSSL libraries. In order to evaluate the proposed countermeasure, a novel attack methodology was developed where the entire secret AES-128 encryption key was recovered from a Raspberry Pi, which has not been achieved before. The FRIES noise generator was pitted against this new attack vector and other known noise generators. The results exhibited that the FRIES noise generator withstood this attack whilst other existing techniques still leaked out secret information. The visual location of the AES-128 encryption algorithm in the EM spectrum and key recovery was prevented. These results demonstrated that the proposed multi-threading software based countermeasure was able to be resistant to existing and new forms of attacks, thus verifying that a multi-threading software based countermeasure can serve to mitigate SCA attacks.
