This study sets out to investigate the relationship between two South African Rand currency indices, ZARX and RAIN, in relation to the gold prices. The ZARX is computed with the formula used to determine the USD currency index (USDX) with the latter being developed by the JSE. Albeit sets of variables have been investigated to determine if any long term relationships exist using the theory of co-integration. The findings suggest that there is no co-integrating relationship between the South African Rand currency indices and the gold price changes over the research period.

South African Rand

This study attempts to explain the source of risk management and diversification benefits that investors may gain from the South African Rand Currency Index (RAIN) as it relates to an equity portfolio with stock market exposure (locally or international). These diversification benefits may result from the negative correlation between RAIN and the South African All Share Index (ALSI). To explain and fully exploit the benefits of RAIN, the main variables that represent South Africa’s trading partner equity and bond markets movements, were identified. To account for the interaction of RAIN with the ALSI, the latter was firstly decomposed into its economic groups and secondly into its various sub-sectors. Various analyses were carried out to determine which variables describe the relationship between the ALSI and RAIN. The variables that describe the relationship with a high adjusted R2, were identified. The findings suggest that when the ALSI is decomposed into its ten economic groups and thirty-seven sub-groups, the quadratic as opposed to linear models using response surface regressions, explained the majority of the variation in RAIN over the entire period. The linear models, however, explained more of the variation in RAIN during the recent 2008/2009 financial crisis.

Social Security Agency

Public institutions, such as the South African Social Security Agency (SASSA) increasingly function in multi-project environments to translate strategies successfully into service-delivery initiatives. However, this ‘projectification’ often causes projects to be designed and executed haphazardly. This can lead to budget and schedule overruns, and the general wastage of an organisation’s resources. Project failures often occur where organisations do not ensure that specific projects are aligned with their core strategies. The purpose of this article is to combine the theories and principles of organisation, management, strategic management, and project management in an effort to pinpoint core determinants that can help establish the extent to which an organisation manages the alignment of its strategic projects. In the present study, the author applied the principles of interdisciplinarity, systems thinking, and organisational integration. The combined core determinants that were uncovered were then used in an empirical investigation of SASSA. The purpose of this investigation is to identify particular challenges the organisation faces in aligning their strategies and projects successfully. Thereafter, a number of recommendations follow to address these challenges.

The article presents a theoretical–methodological proposal to research movements and its connections based on the associations they establish. The first investigation focuses on the transformations of the South African Landless People’s Movement, the second on interactions between Brazilian rural movements and the National Institute of Colonization and Agrarian Reform, the third focuses on the transnational ties of the Brazilian National Confederation of Agricultural Workers. We produce an ontological definition of movements and the state as collectives whose existence is defined by continuous assemblages of heterogeneous and unstable elements. Those collectives are not enclosed analytical units, but contingent and contextual. Methodologically, we suggest the observation of the processes in the long term to grasp the continuous constructions of those collectives, even before they reach public expression. Controversies are analytical categories for understanding which elements allow things to take the course we analyze.

And Task

Although statistical evidence seems to be lacking. it is at present widely acknowledged that organisational culture has the potential of having a significant effect on organisational performance. An analysis of sustained superior financial performance of certain American organisations has attributed their success to the culture that each of them had developed. It has been proposed that these organisations are characterised by a strong set of core managerial values that define the ways in which they conduct business. how they treat employees, customers, suppliers and others. Culture is to the organisation what personality is to the individual. It is a hidden but unifying force that provides meaning and direction and has been defined as the prevailing background fabric of prescriptions and proscriptions for behaviour, the system of beliefs and values and the technology and task of the organisation together with the accepted approaches to these. Recent studies have indicated that corporate culture has an impact on a firm's long-term financial performance: that corporate culture will probably be an even more important factor in determining the success or failure of firms in the next decade; that corporate cultures that inhibit long-term financial performance are not rare and that they develop easily. even in firms that are staffed by reasonable and intelligent people; and that corporate cultures, although difficult to change, can be made more performance enhancing. The purpose of this study, therefore, was to establish the statistical relationship between organisational culture and financial performance.

The Relationship

This paper conducts a search for community structure in the South African company network, a social network whose elements are South African companies listed on the Johannesburg Stock Exchange. Companies are connected in this network if they share one or more directors on their respective boards. Discovered clusters, called communities, can be considered to be compartments of the network working relatively independently of one another, making their distribution and composition of some interest. We test whether the discovered communities of companies are (a) statistically significant, and (b) related to other attributes such as sector membership or market capitalization. We also investigate the relationship between the centrality of a company’s position in the network and its market capitalization.
