The role of science in a crisis: Talks by political leaders during the COVID-19 pandemic.

During the COVID-19 pandemic, science has been prominently featured in institutional communication and political agendas as never before. Governments substantially relied on scientific experts to analyze pandemic trends, develop anti-COVID-19 vaccines and adopt containment strategies. In this paper, we analyze speeches by three political leaders-Boris Johnson (Prime Minister, UK), Sergio Mattarella (President of the Republic, Italy), and Ursula von der Leyen (President, European Commission)-between February 20, 2020, and February 20, 2022, to identify how science was addressed and framed. The results of the quantitative and qualitative exploration of the speeches highlight three main ways in which political leaders view science: a national pride narrative-i.e., science as an instrument and indicator of national pride and international standing of the country; an ethical narrative-i.e., science as an agent of social growth; an integration narrative-i.e., science as a driving force of both European integration and stronger collaboration between knowledge production and industry. The predominant narrative varies in relation to the political leaders' different institutional contexts and roles.

Give science and peace a chance: Speeches by Nobel laureates in the sciences, 1901-2018.

The paper presents the results of a quantitative analysis of speeches by Nobel laureates in the sciences (Physics, Chemistry, Medicine) at the Prize gala dinner throughout the whole history of the Prize, 1901-2018. The results outline key themes and historical trends. A dominant theme, common to most speeches, is the exaltation of science as a profession by the laureate. Since the 1970s, especially in chemistry, this element becomes more domain-specific and less related to science in general. One could speculate whether this happens chiefly in chemistry because its area of activity has been perceived to be at risk of erosion from competing fields (e.g. physics, biology). Over time, speeches become more technical, less ceremonial and more lecture-oriented. Emphasis on broad, beneficial impact of science for humanity and mankind (as emphasised in Nobel's will) is more present in laureates' speeches during the first half of the XXth century, while its relevance clearly declines during the last decades. Politics and its relationship with science is also a relevant topic in Nobel speeches. Particularly between the two World Wars, science is seen as terrain where nationalistic stances and fights among nations could actually find a context for peaceful competition and even cooperation.
