One of the core objectives of economic development is to improve people’s standards of living. However, both standards of living and consumption expenditures are often determined by disposable income, crude oil prices and exchange rate volatility. The current paper employed quarterly time series data from 2002 to 2020 to analyse the responsiveness of household consumption expenditure to the petrol price, disposable income and exchange rate volatility in South African. The empirical outcome suggested that a long-run relationship exists between variables under consideration. Additionally, the current level of consumption expenditure was found to be determined by income level and exchange rate volatility whilst changes in petrol price had no significant effect on short-term consumption expenditure. Based on these findings, the study suggests that the South African policymakers and government authorities implement policies and strategies that enhance both household income and exchange rate. Those strategies may include strengthening the country’s currency, production improvement, inflation rate reduction, and the creation of job opportunities.

This paper examines the long-term relationship between BRICS and US stock markets by employing the cointegration technique and Granger causality to investigate the cointegration and causality direction in the capital markets. The impulse response function it is also employed to evaluate the persistence of the shocks. In the analysis, daily spot stock index returns are used from 2010 till 2017. The main findings of the cointegration analysis indicate that the US and BRICS stock markets are cointegrated and at least one cointegration vector exists among them. The Granger causality test shows that unidirectional causality runs from the US market towards the Russian, South African and Indian stock markets, while there is a bidirectional causal relation between US and Brazil stock markets.

The South African liquid fuels industry is a significant part of the economy. Historically, government policy focused on import substitution industrialization to support industry margins. This approach is called into question by the 2006 shift from net exports to imports and by inflated downstream regulated margins. This study focuses on the regulated petrol price. Import parity pricing regulation has not kept pace with market changes. A policy shift in 1998 towards market-related pricing has not materialized. Instead, regulated margins have increased over the last 20 years in real terms, partly attributable to methodological errors in the regulatory accounting system. The long-term excess of service stations persists despite declining petrol and diesel volumes between 2005 and 2019. Estimates suggest that the petrol price could be lower by 0.70–0.80 rands/litre. Price deregulation is inhibited by political regulation and social policies entangled in regulation.

Nudaurelia capensis β virus (NβV) is an RNA virus of the South African Pine Emperor moth, Nudaurelia cytherea capensis (Lepidoptera: Saturniidae). The NβV capsid is a T = 4 icosahedron that contains 60T = 240 subunits of the coat protein (Mr = 61,000). A three-dimensional reconstruction of the NβV capsid was previously computed from visions embedded in negative stain suspended over holes in a carbon film. We have re-examined the three-dimensional structure of NβV, using cryo-microscopy to examine the native, unstained structure of the virion and to provide a initial phasing model for high-resolution x-ray crystallographic studiesNβV was purified and prepared for cryo-microscopy as described. Micrographs were recorded ∼1 - 2 μm underfocus at a magnification of 49,000X with a total electron dose of about 1800 e-/nm2.

Summary: In the past suicidal behavior among Black South Africans has been largely underresearched. Earlier studies among the other main ethnic groups in the country showed suicidal behavior in those groups to be a serious problem. This article briefly reviews some of the more recent research on suicidal behavior in Black South Africans. The results indicate an apparent increase in suicidal behavior in this group. Several explanations are offered for the change in suicidal behavior in the reported clinical populations. This includes past difficulties for all South Africans to access health care facilities in the Apartheid (legal racial separation) era, and present difficulties of post-Apartheid transformation the South African society is undergoing, as the people struggle to come to terms with the deleterious effects of the former South African racial policies, related socio-cultural, socio-economic, and other pressures.
