Tracking the emergence and spread of SARS–CoV–2 is critical to inform public health interventions. Phylodynamic analyses have quantified SARS–CoV–2 migration on global and local scales, yet they have not been applied to determine transmission dynamics in Canada. We quantified SARS-CoV-2 migration into, within, and out of Canada in the context of COVID-19 travel restrictions. To minimize sampling bias, global sequences were subsampled with probabilities corrected for their countries' monthly contribution to global new diagnoses. A time–scaled maximum likelihood tree was used to estimate most likely ancestral geographic locations (country or Canadian province), enabling identification of sublineages, defined as introduction events into Canada resulting in domestic transmission. Of 402 Canadian sublineages identified, the majority likely originated from the USA (54%), followed by Russia (7%), India (6%), Italy (6%), and the UK (5%). International introductions were mostly into Ontario (39%) and Quebec (38%). Among Pango lineages, B.1 was imported at least 191 separate times from 11 different countries. Introduction rates peaked in late March then diminished but were not eliminated following national interventions including restrictions on non–essential travel. We further identified 1,380 singleton importations, international importations that did not result in further sampled transmission, whereby representation of lineages and location were comparable to sublineages. Although proportion of international transmission decreased over time, this coincided with exponential growth of within–province transmission – in fact, total number of sampled transmission events from international or interprovincial sources increased from winter 2020 into spring 2020 in many provinces. Ontario, Quebec, and British Columbia acted as sources of transmission more than recipients, within the caveat of higher sequence representation. We present strong evidence that international introductions and interprovincial transmission of SARS–CoV–2 contributed to the Canadian COVID–19 burden throughout 2020, despite initial reductions mediated by travel restrictions in 2020. More stringent border controls and quarantine measures may have curtailed introductions of SARS–CoV–2 into Canada and may still be warranted.

Frischenschlager, Haidinger, and Mitterauer (FHM hereafter) reported an evaluation study of predictors for success in Austrian medical undergraduates (Croat Med J. 2005;46:58-65). Since most of the international literature on medical education topics still comes from the USA and the UK, in principle this Central European contribution is much needed and to be welcomed. However, several obvious and grave study limitations make the data and findings of FHM markedly less useful than the authors suggest. Relatedly, in the current absence of other Austrian studies on that topic it is foreseeable that the FHM evidence could be used to inform policy decisions in regards to medical education issues in Austria and, possibly so, elsewhere in Central Europe. I strongly opine that, due to the study’s design deficiencies, this should be avoided. The main purpose of the present comment is therefore to elucidate the shortcomings of this study as well as to stimulate further discussion and research.

The study introduces a Hungarian economic thinker, István Varga*, whose valuable activity has remained unexplored up to now. He became an economic thinker during the 1920s, in a country that had not long before become independent of Austria. The role played by Austria in the modern economic thinking of that time was a form of competition with the thought adhered to by the UK and the USA. Hungarian economists mainly interpreted and commented on German and Austrian theories, reasons for this being that, for example, the majority of Hungarian economists had studied at German and Austrian universities, while at Hungarian universities principally German and Austrian economic theories were taught. István Varga was familiar not only with contemporary German economics but with the new ideas of Anglo-Saxon economics as well — and he introduced these ideas into Hungarian economic thinking. He lived and worked in turbulent times, and historians have only been able to appreciate his activity in a limited manner. The work of this excellent economist has all but been forgotten, although he was of international stature. After a brief summary of Varga’s profile the study will demonstrate the lasting influence he has had in four areas — namely, business cycle research and national income estimations, the 1946 Hungarian stabilisation program, corporate profit, and consumption economics — and will go on to summarise his most important achievements.

Risk analysis in the water utility sector is fast becoming explicit. Here, we describe application of a capability model to benchmark the risk analysis maturity of a sub-sample of eight water utilities from the USA, the UK and Australia. Our analysis codifies risk analysis practice and offers practical guidance as to how utilities may more effectively employ their portfolio of risk analysis techniques for optimal, credible, and defensible decision making.

This chapter points to the ‘pluralization of the lifeworld’ involved in globalization as a key context for changing dissenting spiritualities through the twentieth century. These have included a remarkable upsurge in Spirit-movements that fall under categories such as Pentecostal, charismatic, neo-charismatic, ‘renewalist’, and indigenous Churches. Spirit language is not only adaptive to globalized settings, but brings with it eschatological assumptions. New spiritualities emerge to disrupt existing assumptions with prophetic and often critical voices that condemn aspects of the existing culture, state, and church life. This chapter outlines this process of disruption of the mainstream in case studies drawn from the USA, the UK, India, Africa, and Indonesia, where charismaticized Christianity has emerged and grown strongly in often quite resistant broader cultures.

In recent decades, there has been an increasing number of national policy and strategy papers discussing arts in health in countries around the world. Some of this activity has been driven by national arts bodies, championing the value of the arts in health and wellbeing and advocating for their inclusion within core arts funding and practice. Other activity has been led by health bodies, including health departments within governments and health services themselves. This chapter explores some of the most influential documents and considers their implication for research and practice. It draws on case studies of activity within Ireland, the UK, the USA, Australia, and Nordic countries.

Despite an impressive rise in school enrolment rates over the past few decades, there are concerns about growing inequality of educational opportunity in China. In this article, we examine the level and trend of educational mobility in China, and compare them to the situation in Germany, the Netherlands, the UK and the USA. Educational mobility is defined as the association between parents’ and children’s educational attainment. We show that China’s economic boom has been accompanied by a large decline in relative educational mobility chances, as measured by odds ratios. To elaborate, relative rates of educational mobility in China were, by international standards, quite high for those who grew up under state socialism. For the most recent cohorts, however, educational mobility rates have dropped to levels that are comparable to those of European countries, although they are still higher than the US level.
