Building on Lucas (1988) and Boucekkine et al. (2013), we develop a model in which the impact of population dynamics on per capita GDP and human capital depends on the balance of intertemporal altruism effects toward future generations and class-size effects on an individual’s education investment. We show that there is a critical level of the class-size effects that determines whether a decline in population growth will lead to a decrease or an increase in a country’s long-run growth rate of real per capita income. We take the model to OECD data, using a semi-parametric technique. This allows us to classify countries into groups based on their long-term growth trajectories, revealing patterns not captured by previous studies on the topic.

This study investigates the extent to which a group of Australian preservice and early career secondary school music teachers of East Asian heritage are likely to teach aspects of their heritage music. It is positioned against a background of national multiculturalism and approaches to cultural inclusivity in Australian society, as well as the long-standing notion of ‘Asia literacy’ in Australian education and the national cross-curriculum priority (C-CP) of ‘Asia and Australia’s engagement with Asia’. The study’s findings indicate that the participants identified with their ancestral cultures to varying extents, generally had very limited knowledge of and experience with their heritage music and in general were reluctant to teach their heritage music. The authors suggest that the slow rate of progress towards culturally diversifying Australian music classrooms is related to complex matters and attitudes surrounding race in the country. The study proposes developing Cayari’s concept of ‘Asian spaces’ as a means of increasing the presence of East Asian music in Australian schools and of supporting teachers of East Asian heritage in the workplace. Finally, the authors emphasise that culturally diversifying the content of music classrooms can be undertaken by teachers of any cultural background.

Building on the success of the Soft Drinks Industry Levy (SDIL), new tax proposals have been considered in the public health policy debate in the UK. To inform such debate, estimates of the potential impacts of alternative tax scenarios are of critical importance. Using a modelling approach, we studied the effects of two tax scenarios: (1) a hypothetical excise tax designed to tax food products included in the Sugar Reduction Programme (SRP), accounting for pack size to reduce the convenience of purchasing larger quantities at once; (2) an ad valorem tax targeting products based on the UK Nutrient Profile Model (NPM). Simulations of scenario 1 show a reduction in sugar purchased of up to 38 %, with the largest decreases observed for sweet confectionery with a tiered tax, similar in structure to the SDIL. Expected food reformulation in scenario 1 led to further decreases in sugar purchased for all categories. In scenario 2, under the assumption that the tax would not affect purchases of healthier products, a 20 % tax on less healthy products would reduce total sugar purchased by 4·3 % to 14·7 % and total energy by 4·7 % to 14·8 %. Despite some limitations and assumptions, our results suggest that new fiscal policy options hold a significant potential for improving diet quality beyond what has been achieved by the SDIL and SRP. An estimated increase in consumer expenditures in both scenarios suggests that attention needs to be paid to potentially regressive effects in the design of any new food taxes.

Greenwashing cases holding businesses to account for false or misleading eco-claims are an increasingly visible component of the business and human rights landscape globally. In the European Union (EU), the Unfair Commercial Practices Directive is the centrepiece of regulation for business-to-consumer claims. Within the European Green Deal initiative, the EU is revising this framework, first with the Directive to ‘Empower Consumers for the Green Transition,’ and second the pending proposal for a ‘Green Claims Directive,’ introducing detailed requirements on the substantiation and communication of ‘green claims’ to consumers. If fully adopted, this fundamental reform will impose greater restraints on the discretion of any authority charged with the assessment of green claims and provide more uniform criteria across the EU, resulting in more accurate environmental claims and greater clarity for consumers and businesses alike.

We prove that every locally compact second countable group G arises as the outer automorphism group $\operatorname{Out} M$ of a II1 factor, which was so far only known for totally disconnected groups, compact groups, and a few isolated examples. We obtain this result by proving that every locally compact second countable group is a centralizer group, a class of Polish groups that arise naturally in ergodic theory and that may all be realized as $\operatorname{Out} M$.

The COVID-19 pandemic showed the vital role of Emergency Medical Teams (EMTs) in international surge responses. The EMTs with their internationally skilled team members were able to meaningfully support countries facing the pandemic, especially those who were suffering from scarcity in the quality and quantity of workforce and financial resources within their health systems. This report summarizes the main operational challenges faced by UK-Med and The Polish Center for International Aid (PCPM) Emergency Medical Teams, based on experiences from their 32 COVID-19 deployments. In particular, the paper discusses the hindrances related to Ministries of Health expectations and the changing roles of EMTs during deployments.

The extensive archives of Frederick Lugard are an underused resource for reassessing Lugard himself, reconsidering his impact on specific places and issues, and uncovering African perspectives, refracted as they inevitably are by the perspective of an explorer, military officer, colonial governor, and elder statesman. Literature searches reveal that scholars seldom consult the Lugard papers. They will be of particular interest for scholars from Africa studying the effects on pre-colonial African states of British interference, the onset of foreign rule, and the efforts of African individuals, communities, and elites to resist or co-opt imperial power.

“Sovereign Objects: International Dimensions of Indigenous Repatriation in Canada” explores the complexities of cultural repatriation in Canadian museums, advocating for its recognition as an international issue. By framing repatriation this way, the study acknowledges Indigenous sovereignty and aligns with international legal standards such as the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). The international approach enhances political, social, and cultural outcomes for First Nations peoples, providing a robust legal framework and fostering greater recognition of Indigenous nations as sovereign entities. The manuscript highlights the importance of acknowledging the distinct cultural and political status of Indigenous communities, supported by historical treaties and contemporary legal recognition. It provides case studies, such as the repatriation of human remains from the Royal Ontario Museum to the Rainy River First Nations, to illustrate the practical application of these principles. The study also critically examines the challenges of adopting the discourse of “nations,” including the technical, political, social, and cultural expectations involved. By redefining repatriation as an international issue, this research promotes a deeper understanding of Indigenous sovereignty and facilitates more effective and culturally sensitive repatriation efforts. The manuscript argues that such an approach is essential for ensuring that repatriation processes are respectful, equitable, and aligned with the unique governance structures of Indigenous communities.
