Abstract: The large daisy tribe Gnaphalieae occurs in extra-tropical habitats worldwide, but is most diverse in southern Africa and in Australia. We explore the age and evolutionary history of the tribe by means of a phylogenetic hypothesis based on Bayesian analysis of plastid and nuclear DNA sequences, maximum likelihood reconstruction of ancestral areas, and relaxed Bayesian dating. Early diversification occurred in southern Africa in the Eocene–Oligocene, resulting in a grade of mostly Cape-centred lineages which subsequently began speciating in the Miocene, consistent with diversification times for many Cape groups. Gnaphalieae from other geographic regions are embedded within a southern African paraphylum, indicating multiple dispersals out of southern Africa since the Oligocene to Miocene which established the tribe in the rest of the world. Colonisation of Australia via direct long-distance trans-oceanic dispersal in the Miocene resulted in the radiation which produced the Australasian gnaphalioid flora. The similarly diverse regional gnaphalioid floras of Australasia and southern Africa thus exhibit very different temporal species accumulation histories. An examination of the timing and direction of trans-Indian Ocean dispersal events in other angiosperms suggests a role for the West Wind Drift in long-distance dispersal eastwards from southern Africa.

The Covid-19 pandemic is intensifying existing problems of economic asymmetry, and other injustices, between and within countries and regions around the world. It is thus imperative that sociological studies of education document its socio-cultural implications in different locations and on different scales. It is equally imperative that such studies have a historical perspective that asks what pre-existing social problems have been intensified and how such intensification is happening. This paper responds to these imperatives through the deployment of conjunctural analysis and related crisis and articulation theory. We discuss the global Covid-19 conjuncture as it emerged in the first seven months of 2020 and show how it articulated with the preceding conjuncture. Subsequently, we focus on the issues associated with closing and reopening schools and show how they were intertwined with reconfigurations of the school/home/work nexus. We consider these reconfigurations in two very different locations, Australia and South Africa. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has changed the way we go about our daily lives in ways that are unlikely to return to the pre-COVID-19 levels. A key feature of the COVID-19 era is likely to be a rethink of the way we work and the implications on commuting activity. Working from home (WFH) has been the 'new normal' during the period of lockdown, except for essential services that require commuting. In recognition of the new normal as represented by an increasing amount of WFH, this paper develops a model to identify the incidence of WFH and what impact this could have on the number of weekly commuting trips. Using data collected in eight countries (Argentina, Australia, Brazil, Chile, Colombia, Ecuador, Peru and South Africa), we developed a Poisson regression model for the number of days individuals worked from home during the pandemic. Simulated scenarios quantify the impact of the different variables on the probability of WFH by country. The findings provide a reference point as we continue to undertake similar analysis at different points through time during the pandemic and after when restrictions are effectively removed.

Australia's relationship with South Africa was founded on their being two groups of colonies, and later dominions, in the British Empire. As remote settler societies there were certain affinities, anxiously promoted by South Africa and usually resisted by Australia. Australian prime ministers played a major role in helping to bring about majority rule, but since 1994 the relationship has stiffened. For South Africa, partly for geopolitical reasons, the Commonwealth remains a functional concept; for Australia, it has lost much of its efficacy. Australia and South Africa have also exchanged two significant migrations: of Australian miners and artisans to the Rand around the turn of last century, and of South African emigrants to Australia in our own time. Trade between the two countries is increasing, and a new range and diversity in contact has occurred, with the resumption of full relations since the apartheid years. Given South Africa's disjunction from its immediate past, it is difficult at present to indicate what forms the relationship might take in future. The paper therefore sketches the whole history of interaction between the two countries, drawing attention to its phases and reconfigurations. [ABSTRACT FROM AUTHOR]
