Ethnomathematik : neue Ansätze zu ihrer Theorie und Praxis
No full textVerdugo Rohrer UA. Ethnomathematics : new approaches to its theory and application. Bielefeld (Germany): Bielefeld University; 2010.This work introduces new approaches to the theory and application of ethnomathematics. Ethnomathematics is a field of research focused on the study of different mathematics, which are specific for each (sub-)culture.
First, the author gives a detailed description of a new historiography of ethnomathematics, showing that this field of research has been studied and practiced since the 1920s, when Ewald Fettweis pursued his first research on this subject. Two other important forerunners of ethnomathematics are, according to the author, Otto Raum and Raymond Wilder.
The author proposes a new approach for the theory of ethnomathematics, namely a supplementary interdisciplinary theory that corresponds to the intersection of mathematics, its history and education, and cultural anthropology, ethnology, ethnography and ethnoscience.
Two innovating field researches, undertaken separately in Mozambique and Brazil, are presented by the author. These contribute to the consolidation of the supplementary interdisciplinarity of this field of ethnomathematics

Learning from COVID-19: A roadmap for integrated risk assessment and management across shocks of pandemics, biodiversity loss, and climate change
No full textThe COVID-19 pandemic demonstrated the fragility of international, national, regional, and local risk management systems. It revealed an urgent need to improve risk planning, preparedness, and communication strategies. In parallel, it created an opportunity to drastically re-think and transform societal processes and policies to prevent future shocks originating not only from health, but also combined with those related to climate change and biodiversity loss. In this perspective, we examine how to improve integrated risk assessment and management (IRAM) capacities to address interconnected shocks. We present the results from a series of workshops within the framework of the University of Zurich and University of Geneva. Initiative "Shaping Resilient Societies: A Multi-Stakeholder Approach to Create a Responsive Society". This initiative gathered experts from multiple disciplines to discuss their perspectives on resilience; here we present the key messages of the "Pandemics, Climate and Sustainability” thinking group. We identify a roadmap and selected research areas concerning the improvement of IRAM analysis capacities, practices, policies. We recommend the development of robust data systems and science-policy advice systems to address combined shocks emerging from health, biodiversity loss and climate change. We posit that further developing the IRAM framework to include these recommendations will improve societal preparedness and response capacity and will provide more empirical evidence supporting decision-making and the selection of strategies and measures for integrated risk reduction

Mimesis, artistic inspiration and the blends we live by
No full textThe cognitive linguists Fauconnier and Turner [Fauconnier, Gilles, Turner, Mark, 1998. Conceptual integration networks. Cognitive Science 22, 133-187; Fauconnier, Gilles, Turner, Mark, 2002. The Way We Think: Conceptual Blending and The Mind's Hidden Complexities. Basic Books, New York] have proposed that human creativity may be modeled by their theory of conceptual blending (conceptual integration). I apply blending theory to the pragmatics of fiction, showing how blending theory explains the mechanics of literary mimesis. I investigate how conceptual blends are iteratively chained, arguing that a mimetic blend can be defined as a blend that self-referentially embeds itself into subsequent blends. Using examples from Mario Vargas Llosa's novel Aunt Julia and the Scriptwriter and its cinematic adaptation as Tune in Tomorrow, I show how these mimetic blends can be a literary device whereby an author may offer metafictional social commentary on issues such as the ability of art to incite fictive emotion or even violence on the part of the art-viewer. However, blending theorists typically fail to note important methodological issues raised by whether they are modeling the person who is interpreting (as opposed to who is creating) the conceptual blends. This shortcoming leads me to propose a "space-swapping" hypothesis which argues that the differences between creativity and interpretation can be at least partly explained by the differing roles played by highly similar mental spaces.

Visualizing the Marrow of Science
No full textThis study proposes a new methodology that allows for
the generation of scientograms of major scientific domains,
constructed on the basis of cocitation of Institute
of Scientific Information categories, and pruned using
PathfinderNetwork, with a layout determined by algorithms
of the spring-embedder type (Kamada–Kawai),
then corroborated structurally by factor analysis. We
present the complete scientogram of the world for the
Year 2002. It integrates the natural sciences, the social
sciences, and arts and humanities. Its basic structure
and the essential relationships therein are revealed,
allowing us to simultaneously analyze the macrostructure,
microstructure, and marrow of worldwide scientific
output
Role of sonication pre-treatment and cation valence in the sol-gel transition of nano-cellulose suspensions
No full textSol-gel transition of carboxylated cellulose nanocrystals has been investigated using rheology, SAXS, NMR and optical spectroscopies to unveil the distinctive roles of ultrasound treatments and addition of various cations. Besides cellulose fiber fragmentation, sonication treatment induces fast gelling of the solution. The gelation is independent of the addition of cations, while the final rheological properties are highly influenced by the type, concentration and sequence of the operations since the cations must be added prior to sonication to produce stiff gels. The gel elastic modulus was found to increase proportionally to the ionic charge rather than the cationic size. In cases where ions were added after sonication, SAXS analysis of the Na(+) hydrogel and Ca(2+) hydrogel indicated the presence of structurally ordered domains in which water is confined, and 1H-NMR investigation showed the dynamics of water exchange within the hydrogels. Conversely, separated phases containing essentially free water were characteristic of the hydrogels obtained by sonication after Ca(2+) addition, confirming that this ion induces irreversible fiber aggregation. The rheological properties of the hydrogels depend on the duration of the ultrasound treatments, enabling the design of programmed materials with tailored energy dissipation response
A Tale of Two Surrogates (2025): Author Interview
No full textIn A Tale of Two Surrogates (2025), sociologist Elly Teman and anthropologist Zsuzsa Berend bring years of ethnographic research to life through the vivid and accessible medium of comics. The graphic novel delves into the complex emotional, medical, legal, and ethical terrain of assisted reproduction, following women whose lives intertwine through their experiences as gestational surrogates.
Blending scholarly insight with compelling visual storytelling, A Tale of Two Surrogates bridges the worlds of academia and popular narrative, offering both a window into the lived realities of surrogacy and a model for how comics can communicate social science.
Comics librarian and 2022 Eisner Award judge Jameson Rohrer sat down with Teman and Berend to discuss how this groundbreaking project came to be, what inspired their turn toward the graphic narrative format, and how visual storytelling can reshape the way we teach and understand ethnography
幼兒栄養指数の研究
No full textThe author examined nutritional indices obtained by measuring body length and weight of 785 children in good health (Age ; From one to seven), including brachial circumference and subcutanous fat thickness of abdomen. Indices presented here are G/L (Quetelet), G/L2 (Kaup-Davenport), G/L3 (Rohrer), yearly variations, correlated with brachial circumference and subcutanous fat thickness of abdomen. The results are as follow : 1) Kaups nutritional index (G/L2) was found to be the most suitable for childhood period, suckling period and school-age period index. 2) The curves from these indices coincided approximately with hypothetical curves as presented by T. NAKAMURA in 1952.departmental bulletin pape
