Duelling prospecting rights: a non-custodial second?

This decision of the Northern Cape division dealt with competing "old order prospecting rights" and prospecting rights in terms of the Mineral and Petroleum Resources Development Act 28 of 2002 (MPRDA). The decision represents an important contribution to the resolution of tensions between the old mineral law order and the new regime of Act 28 of 2002

Banking customers’ attitudes toward complaining : their likelihood of voicing a complaint and service recovery they consider appropriate.

This paper measures the attitude of banking customers towards complaining and their likelihood to complain when a service failure is experienced at their current and another bank. Insight is also provided into the service recovery responses customers consider appropriate when a service failure is experienced. The target population included individuals in the Gauteng Province of South Africa who hold a bank account in their personal capacity. An interviewer-administered survey was used to collect data using non-probability quota sampling based upon population group and gender. A demographic profile of respondents, as well as the findings in terms of the aforementioned constructs and related hypotheses is provided. The study found that respondents have a positive attitude towards complaining, and that they are significantly more likely to voice a complaint when experiencing a service failure at their current bank than at another bank. Significant differences also exist with regard to the individual responses respondents consider appropriate when confronted with a hypothetical service failure experienced at their current bank and another bank

Description of a new species of Afroedura (Loveridge) (Reptilia: Gekkonidae) from the south-western Cape

A new gekkonid species, Afroedura hawequensis, is described from the south-western Cape (South Africa). The three species groups recognized in the genus are discussed

Is Brain Gym an Effective Educational Intervention?

Brain Gym® (BG) (BGI, 2008) is a popular commercial program sold by Brain Gym® International (BGI). Making extravagant claims for improved intellectual and physical development, it used in more than 80 countries. While BGI’s claims are persuasive, to date there is little empirical evidence validating the approach. We examine some theoretical assumptions from which BGI was developed, review the efficacy literature, and provide suggestions for making informed decisions about the judiciousness of investing time and resources in this program

The Use of Silver Phenyl Benzyl Phosphate for the Synthesis of Monophenyl Esters of Phosphatidic Acids

Hessel, Morton, Todd, and Verkade have shown that dibenzyl esters of a-glycerophosphatidic acids I (D = acyl group), when shaken at room temperature in an ethanolic medium with hydrogen under slightly more than atmospheric pressure in the presence of a palladium/ active carbon catalyst according to Verkade, Cohen, and Vroege are smoothly hydrogenolyzed; 2 moles of hydrogen per mole of ester are rapidly absorbed, resulting in the formation of the corresponding phosphatidic acids and toluene

A Bayesian analysis for censored Rayleigh model using a generalised hypergeometric prior

Based on a type II censored sample, Bayesian estimation for the scale parameter of the Rayleigh model is carried out under the assumption of the squared error loss function. A generalised hypergeometric distribution with its versatile shape of tails is introduced as a prior, and beta special cases are examined. A simulation study is carried out to investigate the sensitivity of four special cases of this beta prior family in terms of bias, frequentist coverage and mean square error and to determine their effect on robustness. Prediction bounds are derived for the lifetime of unused components using this beta prior family. A data set is used to illustrate and support some of the findings

Susceptibility of Grapevine Sucker and Green Shoot Wounds to Trunk Disease Pathogens

Grapevine trunk disease fungi infect vines through openings, primarily pruning wounds. The main objective of this study was to understand the role of sucker wounds and wounds made by the removal of green shoots from the stems of potted grapevines as potential points of infection for grapevine trunk disease pathogens. Six wine and four table grape vineyards of different ages were sampled in differentproduction areas in the Western Cape grape region of South Africa. Isolations were made from 161 sucker wounds, and fungal pathogens were identified using morphology and DNA sequence analysis of the internal transcribed spacers (ITS1 and ITS2) and the 5.8S ribosomal RNA gene, the translation elongation factor 1alpha or the partial β-tubulin gene. The results show that 62% of the sucker wounds were infected by trunk disease pathogens, including Diaporthe ampelina, Diplodia seriata, Phaeomoniella chlamydospora, Phaeoacremonium minimum, Eutypella microtheca, Cryptovalsa ampelina and Neofusicoccum australe.  Diaporthe ampelina was the most common, followed by D. seriata and P. chlamydospora, in both the wine and table grape sucker wounds. Under glasshouse conditions, wounds made by the removal of young green shoots on one-year-old potted grapevine plants were inoculated with spore suspensions of D. ampelina, E. lata, N. parvum, P. minimum and P. chlamydospora. After four months, all the inoculated pathogens could be re-isolated. This study shows that grapevine sucker and green shoot wounds are susceptible to different grapevine trunk disease pathogens and may therefore play a role in the epidemiology of trunk diseases

The influence of cell phone users' relationship intentions on expectations and perceptions of service recovery

With the first-time cell phone user market quickly shrinking, it is becoming increasingly important for South African cell phone network providers to retain customers by building long-term relationships with them and consistently offering quality service. Despite cell phone network providers' best intentions, service failures do occur. Not all customers want to build relationships with cell phone network providers, and therefore it is important to consider the influence of customers' relationship intentions within a service failure and recovery setting. The purpose of the study was to determine the influence of relationship intention on expectations and perceptions of two service recovery scenarios within the cell phone industry. Non-probability convenience sampling was used to collect data from 605 cell phone users residing in Gauteng. Results indicate that as respondents' relationship intentions increase, so do their expectations that their cell phone network providers should take service recovery action. It was also found that respondents with high and moderate relationship intentions perceived service recovery strategies of their cell phone network providers including an acknowledgement, apology, explanation and rectification of the problem more favourable, compared to a service recovery strategy only rectifying the problem, than those respondents with low relationship intentions
