Authors: Zaversky Fritz , Rández Xabier , Baigorri Javier , Sánchez Marcelino , Ávila-Marín Antonio , Fernández-Reche Jesús , Füssel Alexander 
Published: March 2024

The CAPTure Open Volumetric Air Receiver (OVAR) design is based on ceramic stackable “free floating” absorber modules that form the receiver structure and avoid a complex metallic double membrane design. The novel receiver design has been validated at small-scale (15 kWth) at a solar simulator, as well as on the top of an experimental tower at 300 kWth, up to absorber module outlet temperatures above 900ºC. The novel OVAR concept is attractive for both the concentrated solar power (CSP) sector, as well as for high-temperature process heat supply. The thermal efficiency of the receiver concept is expected to be above 80% at outlet temperatures of 900ºC.

Fostering sustainability competences through co-creation of digital storytelling: Effects of COVID-19 on higher education students’ reflective learning
Authors: Vesala-Varttala Tanja , Pál Ágnes , Kóris Rita 
Published: March 2024

During COVID-19, online collaboration became more accessible than before, enabling higher education students and teachers to organize virtual mobility experiments and run projects with stakeholders across cultures. In this paper, we focus on three blended intensive programs, two in Finland and one in Hungary, to explore how the pedagogical approach of project-based digital storytelling combined with reflective writing contributed to students’ sustainability competence development during the pandemic and after. In these programs, multicultural teams of students worked on real-life digital storytelling projects aimed at driving sustainable changes in people’s thinking, behaviour, and lifestyles. Digital storytelling has proved effective in fostering students’ 21st century skills through engagement and co-creation with the wider world. Based on qualitative content analysis of 67 semi-structured learning journals, we explore students' developments in values-thinking, collaborative, and self-awareness competences during their digital storytelling projects. With insights from student reflections on their virtual, online, and blended learning, we discuss challenges and successes of project-based, collaborative, and reflective learning and propose best practices for using collaborative digital storytelling as a transformative method to foster sustainability competences across cultures.

Laicità e partecipazione politica

Legal secularism and political participation
ABSTRACT: As is well known, the Italian term ‘laicità’ is polysemic and cannot be adequately translated into English. The word ‘secularism’, in fact, only captures certain senses of ‘laicità’. Ultimately, we are dealing with a very complex phenomenon that surely cannot be analyzed with a dichotomic black and white concept. In this paper we are mainly interested in highlighting legal secularism, understood as neutrality. However, we must pay attention to the fact that liberal neutrality, understood as mutual tolerance and impartiality of institutions, is a “committed neutrality” which deeply differs from Max Weber’s uncommitted neutrality to which scientists aspire. On the other hand, the ideal of legal secularism comes into harsh conflict with the partisan spirit that characterizes political life. Democracy is not only respect for rules, but must come to terms with the citizens’ variegated senses of belonging to this or that community. As they say: “My country, right or wrong”. Precisely because of these limits to rational discourse, we believe that legal secularism, in a broad sense, is not fully achievable even in an open society.
