“…The estimated and actual prices of items could therefore be compared 170 times, rather than 188 times (47 × This result indicates that, over the periods of comparison, more prices increased at a rate slower than the rate of inflation than at a rate faster than the rate of inflation. No systematic trend of actual prices exceeding estimated prices is discernable over this period of 32 years, therefore indicating no basis for low inflation credibility as was reported in Rossouw and Padayachee (2007). The two most noteworthy trends over the period of comparison are that the actual prices of:…”

“…A paper in an earlier edition of this Journal (Rossouw & Padayachee, 2007) has shown that inflation credibility in South Africa records low readings when measured in terms of inflation credibility barometers (see also Rossouw & Joubert, 2005a; or Rossouw & Joubert, 2005b in this regard). The central finding of the earlier paper was that official inflation figures are often not viewed as accurate indicators of average price increases in the domestic economy.…”

As inflation credibility in South Africa records low readings when measured in terms of inflation credibility barometers, this note aims at assessing whether actual price movements provide any grounds for low inflation credibility. It compares the price movements of similar items with the rate of inflation over a period of 32 years, i.e. from 1974 to 2006, and discusses the use of an inflation accuracy indicator to compare estimated price levels adjusted by the rate of inflation and actual price levels. Over the period of comparison no systematic over-or under-reporting of changes in prices in terms of the rate of inflation could be detected and the analysis suggests that little or no basis can be found to justify low inflation credibility. Inflation credibility is more likely than not influenced by the most recent purchasing experiences of consumers. Doubts concerning the accuracy of inflation figures could nevertheless result in the general public concluding that monetary policy aiming at the achievement of an inflation target brings only the pain of high interest rates without the tangible benefits of lower inflation, thereby jeopardising the usefulness of an inflation-targeting monetary policy framework.

“…This trend is confi rmed in a previous study by Rossouw and Joubert (2005) who found that dissemination of information improves the understanding of infl ation and increases the credibility of infl ation fi gures. One of their recommendations is that policy initiatives must be supported by means of communication strategies aimed at improving the general level of understanding of infl ation and its measurement (Rossouw & Padayachee, 2007). The inclusion of the concept of infl ation in the ML curriculum will undoubtably increase the awareness of the concept.…”

“…Thus perceptions affect expectations, confi dence, and saving behaviour. A South African study (Rossouw & Padayachee, 2007) focused on infl ation credibility (degree of acceptance of infl ation fi gures by respondents as an accurate refl ection of price increases) among university students, and found that students who studied in the economics fi eld displayed the highest credibility. This trend is confi rmed in a previous study by Rossouw and Joubert (2005) who found that dissemination of information improves the understanding of infl ation and increases the credibility of infl ation fi gures.…”

734This article reports on a study carried out with a group of 83 Mathematical Literacy teachers who were enrolled for an Advanced Certifi cate in Education programme at a South African university. The purpose of this study was to explore the teachers' conceptions of the infl ation rate. Data for the study was generated from the teachers' responses to specifi c test items that formed part of their classroom assessment. The study was interpretative in nature, utilizing a document analysis of the teachers' written responses. The analytic framework was drawn from Sfard's processobject understanding theory. The fi ndings reveal varying levels of engagement with the concept. One quarter of the teachers were able to move easily between using the infl ation rate signifi er both as a process and as an object, another quarter of the teachers were able to access a process understanding of the infl ation rate concept but struggled to use the infl ation rate signifi er as an object. Two other groups of teachers displayed fundamental problems with the process-object duality of the concept of percentage, which limited their use of the infl ation rate signifi er.

Biodegradable materials suitable for medical application with improved corrosion resistance and good biocompatibility along with enhanced mechanical properties are the need of the hour. Such properties in Mg-Zn-Ca glass forming alloy used as a metal matrix can be obtained through proper reinforcement. Hydroxyapatite (HA) which is a mineral constituent of natural bone has a wide range of medical applications because of its excellent biocompatibility and bioactivity. They promote bone cell adhesion and osteoblastic proliferation. In the present study, the influence of HA particle (HA p ) addition on the glass forming ability, corrosion resistance, mechanical behavior and cytocompatibility of Mg 66 Zn 30 Ca 4 alloy has been investigated. The addition of HA p decreases the glass forming ability of Mg 66 Zn 30 Ca 4 alloy. Significant improvement in corrosion resistance along with marginal improvement in mechanical properties is observed upon addition of HA p . Moreover, HA p incorporation into Mg 66 Zn 30 Ca 4 metallic glass has enhanced the cell viability and cell adhesion of human osteoblast-like cell (MG63) cells, complementing the excellent biocompatibility, bioactivity, osteoconductivity and osteoinductivity of hydroxyapatite mineral due to its biomimetic nature. HA reinforcement is not only a promising approach to improve the corrosion resistance, but also offers a biomimitic interface to enhance osseointegration and overall competence of orthopedic implants.
