    Participatory sense-making in deep disagreements: enriching multi-modal theory of argumentation with the enactive approach to linguistic bodies
    (Elsevier BV, 2026-07) Candiotto, Laura; Kiš, Serhij
    Deep disagreements – conflicts that concern issues of existential importance – pose a challenge for traditional argumentation theories. This paper explores how such disagreements unfold in dialogical exchanges, particularly in emotionally and existentially charged contexts. Using the movie We Live in Time (2024) as a case study of deep disagreement on procreation, we note that the multi-modal theory of argumentation seems initially promising but is ultimately limited as far as overcoming deep disagreements is concerned. This paper aims to remedy these limits of multi-modal argumentation by utilizing the enactive tool of participatory sense-making. While multi-modal argumentation facilitates resolution through mutual understanding and seeking of interlocutor’s shared grounds in most mundane disagreements, we argue that it remains insufficient in deep disagreements. This is because in deep disagreements the shared grounds between the interlocutors' respective positions are missing. By discussing qualitative sociological research on reproductive decision-making, we argue that what is needed in such cases is co-creation of new meanings between interlocutors. We propose integrating the enactive approach to participatory sense-making with multi-modal argumentation and we test the efficacy of this intervention by analyzing some crucial scenes of We Live in Time. Our final picture explains how participatory sense-making can help couples transform their deep disagreements into new meanings over a span of a shared form of life.

    Ligand-engineered ZnS quantum dots synthesized from substituted thioureas: scalable production, polymer grafting, and emissive film fabrication
    (Royal Society of Chemistry) Jemelka, Jiri; Loghina, Liudmila; Frumarova, Bozena; Rodriguez- Pereira, Jhonatan; Slang, Stanislav; Houdek, Jakub; Kurka, Michal; Jambor, Roman; Vlcek, Miroslav
    Zinc sulfide (ZnS) quantum dots (QDs) were synthesized using a series of substituted thioureas as single-source sulfur precursors in a high-temperature 1-octadecene medium. The hot-injection method offered excellent reproducibility and enabled straightforward scale-up to multigram quantities without compromising particle size or optical characteristics. The as-prepared ZnS QDs exhibited a high organic content (∼46 wt.%), originating from in situ-generated surface ligands, which was quantitatively determined through acid digestion. This surface composition provided a versatile platform for subsequent ligand exchange. Functional ligands, including 2-mercaptopropionic acid (2-MPA), bis[2-(methacryloyloxy)ethyl] phosphate (BMEP), and 10-(phosphonooxy)decyl methacrylate (PODM), were successfully introduced, yielding hydrophilic, hydrophobic, and polymer-reactive ZnS QDs. Structural analysis (XRD, STEM, EDS, FTIR, XPS) confirmed the formation of cubic ZnS QDs with uniform particle sizes (6-8 nm) and verified the incorporation of the new ligands without altering the ZnS core. Optical measurements revealed size-dependent absorption and emission properties across the thiourea series, as well as pronounced ligand-dependent modulation of photoluminescence intensity and decay kinetics. Finally, pristine and functionalized QDs were incorporated into PMMA, PVK, PEG, and methacrylate-based copolymers to form uniform emissive thin films, with AFM demonstrating smooth surface morphology for most systems. These results establish substituted thioureas as effective precursors for scalable ZnS QD synthesis and highlight ligand engineering as a powerful tool for tuning surface chemistry and enabling direct polymer integration.
