We note with great enthusiasm the recent cabinet decision on the roll-out of antiretrovirals (ARVs) in South Africa. According to information from the Treatment Action Campaign (TAC) on the cabinet document, ‘Treatment Options to Supplement Comprehensive Care for HIV/AIDS in the Public Health Sector’ presented to MINMEC on 9 May 2003, we note, among other items, that the document may underestim...

Based on a simplified nonlinear lumped element model of the electrodynamic loudspeaker in either a closed or a vented cabinet, a new nonlinear controller is derived, simulated and implemented on a DSP. The Volterra series expansion, a well known functional expansion to model nonlinear systems, is used to estimate the nonlinear parameters from distortion measurements. The controller is directly ...

According to Olson’s concept of encompassing organizations, strong two-party, plurality oriented political systems should create more ‘responsible’ public policies than ‘weak’ multi-party governments based on proportional representation. An empirical measure of ‘encompassment’, termed popular cabinet support, is developed and tested in a multivariate controlled statistical analysis of 18 indust...

Political parties bargain over the allocation of cabinet portfolios when forming coalition governments. Non-cooperative theories of legislative bargaining typically predict that the “formateur” enjoys a disproportionate share of government ministry positions. However, empirical evidence indicates that parties receive shares of portfolios proportional to their share of legislative seats that a g...

Objective: In this article, we analyze the formal rules of cabinet decision-making processes within and across constitutions in parliamentary and presidential systems. Argument: We argue that the degree of power sharing between chief executives and cabinet ministers should be considered in a continuum scale, and that the level of dominance of the chief executive over cabinets varies from a cent...

On 9 December 2002, the then minister of education, Professor Kader Asmal, announced that the cabinet had approved the final proposals for the restructuring of the institutional landscape of higher education in South Africa. These proposals were the culmination of a wide-ranging consultative process on the restructuring of the HE system that had begun in the early 1990s, and which had produced ...

In order to eliminate the internal condensation of enclosed switchgear cabinet, this paper introduced a subminiature and high-performance dehumidifier based on semiconductor refrigeration technology. This equipment utilized a Fuzzy self-tuning PID intelligent controller to monitor the humidity change in the cabinet continuously and judged the dehumidifier start-stop automatically. Besides, real...

Laboratory work with pathogenic microorganisms should be performed in a ventilated safety cabinet. A minimum airflow of 0-5 metres per second through the working aperture has been recommended, with discharge of the exhaust air through a filter, then into the open air (Department of Health and Social Security, 1970). Such a unit must be permanently installed. There are possible advantages to a p...
