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

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

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

The interrelationships between customer satisfaction, brand loyalty and relationship intentions of Generation Y consumers towards smart phone brands

Smart phone marketers are finding it difficult to maintain market share in a market characterised by fierce competition and continued new product development. Generation Y consumers generally have a good command of technology and engage in technology-related behaviour such as texting, tweeting and web-surfing. When it comes to the adoption of smart phone applications, it is believed that Generation Y is leading the way. To retain Generation Y consumers, it is critical for organisations to ensure that customer satisfaction is achieved, brand loyalty has to be generated and meaningful long-term relationships with these consumers should be established. In this regard, this study aims to determine the interrelationships between customer satisfaction, brand loyalty and the relationship intentions of Generation Y smart phone users. Self-administered questionnaires were fielded among 395 Generation Y smart phone users living in Gauteng, South Africa. Results indicate significant and positive interrelationships between customer satisfaction, brand loyalty and relationship intention

Remarks on the modelling of molecular binding forces in the Glue-DNT interaction

948-951The interactions between cyanoacrylate type of glue and model compounds for dinitrotoluene (DNT) and trinitrotoluene (TNT) are investigated using mainly spectroscopic techniques. Electrostatic fields emanating from dispersion and dipole interactions are thought to dominate the energy of interaction without any evidence for hydrogen bonding between the glue and any of the substrates. Vibronic spectral data strongly suggests polarization of the vibrational manifolds of the substrates. Careful analysis of nuclear magnetic resonance (nmr) spectral data reveals a good correlation between the nmr chemical shifts and the measured infrared shifts in the glue matrix. This profound observation may have implications for theoretical calculations of nmr chemical shifts

Venous bicarbonate and creatine kinase as diagnostic and prognostic tools in the setting of acute traumatic rhabdomyolysis

Background. Myorenal or crush syndrome often develops following soft-tissue traumatic injury. It is a spectrum of disease that may result in severe renal dysfunction and kidney injury requiring renal replacement therapy.Objectives. To review a large cohort of patients with so-called myorenal or crush syndrome and assess the biochemical markers of venous bicarbonate and creatine kinase as predictors for the development of acute kidney injury (AKI).Methods. All patients with myorenal syndrome who presented to Khayelitsha District Hospital, Cape Town, South Africa (SA), and Ngwelezana Hospital, Empangeni, KwaZulu-Natal, SA, between January and December 2017 were identified and reviewed.Results. A total of 212 patients were included in the study. At both hospitals, 94% of the patients were male. Using the Pearson correlation coefficient, we compared creatinine kinase (CK) against serum creatinine. The mean CK level was 5 311.8 U/L and the mean creatinine level 133.457 μmol/L. The r-value was 0.2533. Although this is a technically positive correlation, the relationship between the variables is weak. Using the Pearson R Calculator, we inserted the r-value to calculate the p-value. The p-value was 0.000208. When comparing venous bicarbonate (HCO3) against creatinine, the mean HCO3 level was 22.296 mmol/L and the mean creatinine level 162.053 μmol/L. The r-value was –0.3468. Although this is a technically negative correlation, the relationship between the variables is weak. Using the Pearson R Calculator, we inserted the r-value to calculate the p-value. The p-value was 0.000013. The inverse ratio shown with HCO3 v. creatinine, although still a weak correlation, is significantly better in predicting an increase in creatinine compared with the weak positive correlation of CK v. creatinine.Conclusions. Although both venous HCO3 and CK showed a weak correlation with creatinine, the former performed significantly better in predicting AKI. In a resource-constrained system, we recommend that HCO3 be measured to assess patients with crush injury and that CK be regarded as a complementary modality

Cohomogeneity one manifolds and selfmaps of nontrivial degree

We construct natural selfmaps of compact cohomgeneity one manifolds with finite Weyl group and compute their degrees and Lefschetz numbers. On manifolds with simple cohomology rings this yields in certain cases relations between the order of the Weyl group and the Euler characteristic of a principal orbit. We apply our construction to the compact Lie group SU(3) where we extend identity and transposition to an infinite family of selfmaps of every odd degree. The compositions of these selfmaps with the power maps realize all possible degrees of selfmaps of SU(3).Comment: v2, v3: minor improvement

Regularity of Cauchy horizons in S2xS1 Gowdy spacetimes

We study general S2xS1 Gowdy models with a regular past Cauchy horizon and prove that a second (future) Cauchy horizon exists, provided that a particular conserved quantity $J$ is not zero. We derive an explicit expression for the metric form on the future Cauchy horizon in terms of the initial data on the past horizon and conclude the universal relation A\p A\f=(8\pi J)^2 where A\p and A\f are the areas of past and future Cauchy horizon respectively.Comment: 17 pages, 1 figur
