The Successive Lives of Eka-Manganese aka Element 43" DESCRIPTION:Livestream https://youtu.be/Egi8CmGJ6SM \nSeries: Chemistry \nSpeaker: Brigitte Van Tiggelen (Science History Institute) \nTalk: « It’s Not Elementary! The Successive Lives of Eka-Manganese aka Element 43 » \nAbstract \nIn 1988\, a contribution appeared in the journal Nuclear Physics\, signed by the Belgian nuclear chemist Pieter Van Assche with the title “The ignored discovery of the element Z = 43”. The author claimed that the Italian physicists Carlo Perrier and Emilio Segrè were wrongly credited with the first observation of the element with atomic number 43\, and that he was providing convincing arguments that the Berlin-based research team Walter Noddack\, Ida Tacke and Otto Berg who had announced to have discovered the element along with element 75 back in 1925 should in fact be credited with its discovery. Less than ten years later\, a paper by the Japanese radiochemist Kenji Yoshihara published in Radiochemica acta revisited the case of nipponium\, a new element that another Japanese chemist\, Masataka Ogawa had claimed to have discovered in 1908. Yoshihara suggested that the new element Ogawa had isolated and observed could have been what is now called rhenium\, or dvi-manganese\, and not eka-manganese as initially claimed. The story of nipponium bears some similarities with that of masurium: a claimed discovery that was never confirmed\, it has also caught the attention of scientists and historians alike over the last 25 years\, triggering passionate debates\, the unearthing of hitherto untapped historical material and the reappraisal of the scientific evidence. Masurium\, nipponium\, but also lucium\, davyum\, ilmenium\, pelopium or polinium\, are often mentioned in the « biography » of Tc (technetium). This talk will use this biographical approach to the chemical elements to examine what it tells about discoveries\, their context and their narratives.

Modelling the urban metabolism in light of the concept of 'agency'" DESCRIPTION:Livestream https://youtu.be/Nd81pK9G1u8 \nSeries: Urban Metabolism \nSpeakers: Nicola Bertoldi\, Ehsan Ahmadian\, Elisabetta Rosa\, and Daniela Perrotti (UCLouvain\, Urban Metabolism lab) \nAbstract \nAs part of the “AISt-nexus” project\, this session presents work-in-progress research aiming to establish a model decision system for supporting support researchers\, practitioners\, and policymakers interested in studying metabolic dynamics at the urban level. This model decision system is informed by a conceptualization of how different kinds of stakeholders as agents shape and are shaped by such dynamics. Users can provide as input a specification of the agents and dynamics in which they are interested based on a characterization of those same agents\, which is built into the system’s structure. The output they receive is a selection of models or possible combinations of models – such as material flow analysis (MFA)\, life-cycle analysis (LCA)\, etc. – that are best suited to represent those same agents and dynamics. The present session focuses on how the analysis of the concept of “agency” that underlies the decision system’s structure can inform the output of such a selection process. \nTo this aim\, we will present how the system’s structure was established as a result of the cross-fertilization between two components: (1) a characterization of the concept of “agency” relative to urban metabolism studies through computational methods and critical analysis of urban metabolism literature (across urban\, industrial\, and social ecology) and foundational texts in social systems theory and systems ecology; (2) a literature-based characterization of urban metabolism models describing how different modelling methods engage with the concept of “agency” at various levels and according to indicators such as boundary-spanning across disciplines\, specificity\, and inclusiveness with respects to the kinds of agencies modeled and model’s depth of analysis. The articulation between (1) and (2) will be discussed to show how the decision system can bridge existing gaps between the conceptualization and modeling of stakeholders’ influence on metabolic dynamics\, especially from a “stock-flow-practice nexus” perspective. \nThis work is supported by the Fonds de la Recherche Scientifique – F.S.R.-FNRS\, Belgium\, under Grant(s) n° MIS-F.4536.22\, Mandat d’Impulsion Scientifique / Incentive Grant for Scientific Research.
