Weaning patterns are reflected in strontium-calcium ratios of juvenile skeletons

As human milk is exceptionally low in strontium-calcium ($\text{Sr}\text{Ca}$) ratios, but solid foods are relatively high, it should be possible to examine the pattern of dietary supplementation and the age of weaning in prehistoric groups by reference to the $\text{Sr}\text{Ca}$ ratios of juvenile skeletons. The data are presented that support this rationale, along with an investigation of the Sr/Ca values of juvenile and adult skeletons from a medieval Arab graveyard. The $\text{Sr}\text{Ca}$ data from these skeletons are shown to coincide with the age-curves expected in theory, suggesting that new palaeodemographic information is indeed obtainable from $\text{Sr}\text{Ca}$ studies. However, until further research is conducted, the technique provides a functional estimate of weaning patterns that is only suitable for comparative purposes. Additional research should clarify the relationship of functional to actual estimates of dietary supplementation and weaning.     

Pandemics,transformations and tourism: be careful what you wish for

Abstract

Disease outbreaks and pandemics have long played a role in societal and economic change. However, the nature of such change is selective, meaning that it is sometimes minimal and, at other times, and change or transformation may be unexpected, potentially even reinforcing contemporary paradigms. A comprehensive overview of pandemics and their effects is provided. This is used to help contextualise the COVID-19 pandemic, its impact on tourism and government, industry and consumer response. Drawing on the available literature, factors that will affect tourism and destination recovery are then identified. Some measures will continue or even expand present growth orientations in tourism while others may contribute to sustainability. It is concluded that that the selective nature of the effects of COVID-19 and the measures to contain it may lead to reorientation of tourism in some cases, but in others will contribute to policies reflecting the selfish nationalism of some countries. However, the response to planetary limits and sustainable tourism requires a global approach. Despite clear evidence of this necessity, the possibility for a comprehensive transformation of the tourism system remains extremely limited without a fundamental transformation of the entire planet.     

ENERGY,ENVIRONMENT AND INTERNATIONAL FINANCIAL INSTITUTIONS: THE EBRD'S ACTIVITIES IN THE WESTERN BALKANS

This article examines the relationship between the EBRD's project portfolio in the Western Balkan energy sector, and the region's main energy and environment problems. It argues in favour of geographically centred appraisals of the environmental sustainability of multilateral energy investment. Empirical analyses have been placed within the context of this bank's broader policy mandate to support the reconstruction and development of, among other aspects, energy operations in the post‐socialist states of Eastern Europe and Central Asia, while promoting environmental sustainability. The article categorizes the Western Balkans' energy and environment problems into two main groups: the failure to shift away from carbon‐emitting sources of energy, and the inability to introduce efficient technologies in the generation, transmission, distribution and consumption of energy. It investigates the level to which these issues have been represented in the Bank's energy investment activities in the region. The EBRD's ability to fund energy and environment projects has been affected by, among other factors, the decision‐making process within the relevant governments and the Bank itself. These processes are related to the structural legacies of central planning and the organizational cultures embedded within the EBRD at its inception.     

Race and hospitality: Allied troops of colour on the South African home front during the Second World War

Though often marginalised in histories of the Second World War, South Africa, in addition to contributing manpower and economic support to the Allied war effort, was a transport hub and a site for military training. Millions of Allied servicemen and women spent time in South Africa, which became an important node in both imperial and Allied wartime networks. Examining the varied experiences of Allied personnel of colour in South Africa, with a focus on the Māori battalion, this essay, working towards a transnational social history of the conflict, highlights the ways in which wartime hospitality both reflected and subverted ideologies and practices of racial segregation.
