SARS-CoV-2 exploits angiotensin-converting enzyme 2 (ACE2) as a receptor to invade cells. It has been reported that the UK and South African strains may have higher transmission capabilities, eventually in part due to amino acid substitutions on the SARS-CoV-2 Spike protein. The pathogenicity seems modified but is still under investigation. Here we used the experimental structure of the Spike RBD domain co-crystallized with part of the ACE2 receptor, several in silico methods and numerous experimental data reported recently to analyze the possible impacts of three amino acid replacements (Spike K417N, E484K, N501Y) with regard to ACE2 binding. We found that the N501Y replacement in this region of the interface (present in both the UK and South African strains) should be favorable for the interaction with ACE2, while the K417N and E484K substitutions (South African strain) would seem neutral or even unfavorable. It is unclear if the N501Y substitution in the South African strain could counterbalance the K417N and E484K Spike replacements with regard to ACE2 binding. Our finding suggests that the UK strain should have higher affinity toward ACE2 and therefore likely increased transmissibility and possibly pathogenicity. If indeed the South African strain has a high transmission level, this could be due to the N501Y replacement and/or to substitutions in regions located outside the direct Spike–ACE2 interface but not so much to the K417N and E484K replacements. Yet, it should be noted that amino acid changes at Spike position 484 can lead to viral escape from neutralizing antibodies. Further, these amino acid substitutions do not seem to induce major structural changes in this region of the Spike protein. This structure–function study allows us to rationalize some observations made for the UK strain but raises questions for the South African strain.

S. Grey 3 c 12 is a miscellany of Latin poems in the South African Library, Cape Town. It is one item in a collection of manuscripts, and a much larger number of printed books, given to the library in 1861 by Sir George Grey, governor of the Cape. At the time of the gift, he had relinquished his office for a similar post in New Zealand, where he had been governor also before coming to South Africa. While in New Zealand for the second time, he formed another but smaller collection of manuscripts, now in the Public Library at Auckland. Both collections are the work of an amateur bibliophile, a gentleman of private means, who assembled with intelligence and good taste.

In this article, the question in focus is the church and Christianity’s prophetic responsibility towards society, and how in the specific case of the South African-born theologian Gerald John Pillay, his prophetic voice should be characterised. The question is addressed as to whether he was an activist at the barricades or a soft-spoken intellectual in his views on society. After a brief discussion on his bio, the focus is on the phenomenon of being a prophet towards society. Then, the focus, largely based on a literature study, moves to Pillay’s perspectives on the South African and New Zealand contexts, and then a discussion of some of Pillay’s writings on being a prophetic voice follows. Finally, in the conclusion, his specific style and model of being a prophetic voice are analysed.

Scant Attention

Indigenous personality research often remains limited to its cultural context of origin. Previous cross-cultural examinations of indigenous models have typically focused on East–West comparisons and have paid scant attention to the predictive validity of indigenous models in new contexts. The present study addresses the replicability of the South African Personality Inventory (SAPI) and its predictive validity for family orientation and well-being in New Zealand European ( n = 428) and Māori students ( n = 226). The structure of the SAPI in New Zealand was equivalent to the structure identified in South Africa and had metric invariance between the two New Zealand groups. The SAPI social-relational scales explained additional variance above neuroticism, extraversion, conscientiousness, and openness in family orientation, but not in well-being. Mediation path analyses suggested that personality played a similar role for family orientation and well-being in the two groups when assessed by the SAPI, although group differences were suggested when using the Big Five Inventory. Our findings indicate that indigenously derived models, developed with the aim to represent culturally salient concepts, can be relevant well beyond their culture of origin and offer an enriched understanding of personality’s role for important outcomes across cultures.

Accounting Faculty

Purpose – The purpose of this paper is to examine the profiles of Australian, New Zealand and South African accounting faculty members. Additionally, the study investigates whether there are any differences in research productivity of the accounting faculty between countries as measured by peer-reviewed academic journal output. Design/methodology/approach – This archival study uses details obtained from webpages of Departments of Accounting in the three countries to construct a profile of accounting academics. Findings – Significant differences in the profiles of accounting academics were found that can be attributed to the institutional factors that exist in each country. Staffs at the junior lecturer and lecturer levels are more likely to be female, while senior lecturers and professors in all three countries were more likely to be male. While Australia and New Zealand had a similar percentage of staff holding PhD or equivalent academic qualifications, only a small proportion of the South African faculty held PhD or equivalent qualifications. A greater proportion of the South African faculty was professionally qualified compared to their Australian and New Zealand counterparts. New Zealand accounting faculty was more productive than their Australian colleagues, with South African academics being the least productive. Academics holding a doctoral qualification or equivalent were more productive than those that did not. Research limitations/implications – The research limitations relate to the use of websites as the primary data source. Incompleteness of information, inconsistencies in the type of information presented and a lack of comparability of information across institutions and countries may have led to some errors and omissions. However, given the relatively large sample size of 2,049 academics, this was not deemed to materially affect the final analysis. Originality/value – The paper provides an important contribution to the literature on accounting academics. It is the first of its kind to present a comprehensive “snapshot” of the profiles of accounting academics at the universities in Australia, New Zealand and South Africa.
