For over two decades now, the application of Citizen Science to Education has been evolving, and fundamental topics, such as the drivers of motivation to participate in Citizen Science projects, are still under discussion. Some recent developments, though, like the use of Artificial Intelligence to support data collection and validation, seem to point to a clear-cut divergence from the mainstream research path. The objective of this paper is to summarise the development trajectory of research on Citizen Science in Education so far, and then shed light on its future development, to help researchers direct their efforts towards the most promising open questions in this field. We achieved these objectives by using the lens of the Affordance-Actualisation theory and the Main Path Analysis method.

The Russian invasion of Ukraine and the recognition of the rising challenge from China have resulted in a closer alignment of American, British and French strategic interests. This policy paper explores how the strategic relationship between the United States, the United Kingdom and France has evolved amid this changed threat environment. The Russia–Ukraine war exposed the limitations of France's policy of 'strategic autonomy' and reasserted the importance of an American role in European security. The war has re-focused attention upon the Lancaster House framework in which the UK and France have the potential to enhance their contribution to European defence. The UK still regards its 'special relationship' with the US as being of critical importance to its foreign policy. But the UK's diminishing military power makes it a less valuable ally to the US whose attention is increasingly upon the Indo-Pacific region. The paper argues that the alignment between the three countries has been closer over the Russian war in Ukraine compared to attitudes towards China, where tensions between France and the 'Anglo-Saxons' persist. France has been unwilling to adopt the American approach towards China and has stuck to its vision of a multipolar world. The AUKUS deal arranged between the US, UK and Australia had the effect of alienating France. The policy paper contends that the temporary alignment between US, UK and French interests will erode as long-standing conflicts of interest re-emerge. In particular, the unpredictability of US leadership will damage the trilateral relationship if Donald Trump regains the presidency in November 2024. [ABSTRACT FROM AUTHOR]

Economic inequality, in terms of income or wealth, is one of the most complex and perplexing challenges of our current capitalist economic system. While the dynamic relationship between income inequality and economic growth has been extensively investigated (since the beginning of the last century), the dynamic link between wealth inequality (or wealth concentration) and economic growth has been largely ignored in the literature, taking more attention in recent years. This paper asserts that the accumulation of non-productive assets/luxury goods is an important determinant of wealth inequality, as well as a determinant of the relationship between wealth inequality and economic growth. In this paper our aim is to show that an increase in wealth inequality is associated with a slowdown in economic growth. In particular, the paper shows that there is a negative relationship between wealth inequality and economic growth in France because poor households own a relatively large fraction of non-productive luxury goods. Nevertheless, this is not the case in the US, which is what explains that such negative relationship is not observed there. We conclude that a redistribution of wealth (from the rich to the poor) is important for attaining a sustained economic growth performance. • This paper contributes to the analysis of economic growth and wealth inequality in France and the United States. • We propose a macroeconomic model that includes both productive and non-productive assets. • Economic growth slows as the aggregate stock of non-productive assets increases as wealth inequality increases. • Redistribution will enrich the poorest households and therefore decrease their propensity to own unproductive assets. • Wealth inequality and economic growth may have a non-linear relationship.

Recent Sustainable Development Goals (SDG) reports have highlighted the inadequacy of environmental sustainability efforts. Thus, it is clear that current efforts towards environmental sustainability (SDG 13) and affordable and clean energy (SDG 7) policies are insufficient and a comprehensive policy agenda is needed. Existing literature limitedly addresses the determinants of environmental sustainability but relatively ignores the impact of nuclear energy research and development investments (NCI) and green environment on environmental quality. The motivation of this study is to fill this research gap and propose an overarching policy structure to achieve SDGs. In this context, this study investigates the effects of green environment, economic growth, human capital, and NCI on environmental sustainability comparatively for the United States and France through the Asymmetric Autoregressive Distributed Lag, which considers structural break. Based on the empirical analysis results, economic growth and trade openness harm environmental sustainability, while positive shocks in NCI improve environmental quality in both countries. Negative NCI shocks deteriorate environmental quality in the United States but not France. In conclusion, this study provides detailed environmental sustainability policies for the United States and France. [ABSTRACT FROM AUTHOR]
