    Postgraduate critical mass for sustainable development : experiences from Durban University of Technology
    (Business Perspectives, 2015) Chule, Siyabonga Goodwill; Dzwairo, Bloodless; Moyo, Sibusiso
    Human capacity growth is analyzed quantitatively and tackled critically for the functional purpose of meeting the chal-lenges of sustainability in the South African context. The progression of Bachelor of Technology degree (BTech) stu-dents is studied for the academic period 2004-2014 as these form a potential pool of postgraduate candidates at the Durban University of Technology (DUT). The first objective of the research study involved analyzing the enrolment and graduation rates. The second objective was to assess the type of enrolments (part-time/full-time) and to correlate the gender, the ethnic groups and the demographic factors. The third objective was to quantify the academic year fre-quencies for graduates in the enrolled qualifications and finally the authors evaluated and scaled the popularity of qua-lifications in the respective faculties. The findings in this research indicated a ‘strong growth’ of expertise for the human capacity development, presented by a concentrated large number, at an erratic progress for sustainability of the potential pool of postgraduate students. The indicated ‘strong growth’ was found in the Management Sciences Faculty within the Business Studies Unit, and in Civil Engineering in the Civil Engineering and Surveying Department. The lack of strong growth in other areas within some of the qualifications in faculties could be due to a lack of the diverse expertise in other disciplines of Manage-ment Sciences and Engineering amongst other reasons. In the Applied Sciences the low numbers of scientists indicates the low throughput as a reflection of low enrolments. The enrolments numbers are low but there is a huge potential as demand continues to increase so to realize the skills targets in the knowledge economy as outlined by the South African National Development Plan targets for 2030. Addi-tionally, the high numbers of engineers are key towards South Africa’s infrastructure development.

    Computations in determining a financial proxy which optimizes de-trended stochastic asset prices under fixed-mix portfolio strategies
    (2014) Chule, Siyabonga Goodwill; Moyo, Sibusiso; De Beer, Marie
    The performance of portfolios of a fixed-rate asset and a risky asset of major companies in a South African market index the FTSE/JSE with strategies which rebalances fixed proportions of wealth in every rebalancing period is analysed in a long term. Recent findings in portfolio management theory by Dempster, Evstigneev and Schenk-Hoppé (2010, 2008, 2007, 2003) and by Browne (1988) note optimality of fixed-mix portfolios which assert fast exponential growth in stationary markets. A quantitative analysis is performed to analyse quantifiable measures in order to optimize the application of self-financing constant rebalanced portfolio strategies that contribute to the financial engineered prospects suggested by Dempster et al. (2010) for fixed-mix portfolios. The comparative performance of fixed-mix portfolios with a proxy strategy and without proxy strategy relative to a buy and hold strategy shows the superiority of fixed-mix portfolios in generic market conditions. The research extends the utilization of constant rebalanced self-financing portfolio investment strategies by assessing the market price of risk under the mean-variance model of Markowitz (1952). Effective implementation tactics of the strategy are examined by focusing on the market risk and the financial risk. The frequent reversals and trending of stochastic asset prices in the financial market are analysed to adjust the market price of risk by considering tradable financial securities to determine the financial proxy of de-trending. The proxy hypothesis which evaluates the stationary financial condition in a fixed-mix portfolio is validated by an option-based myopic strategy using a lookback straddle option. A myopic strategy is a strategy which considers a single period ahead, Fabozzi, Forcardi and Kolm (2006). The realised growth under a financial proxy is found to have a linear strategic asset allocation with a low degree of concavity relative to a buy and hold performance in the market risk of self-financing portfolio strategies.
