How Social‐Symbolic Work Changes Places
Journal of Management Studies, Volume 62, Issue 8, Page 3425-3460, December 2025.Abstract We advance the social‐symbolic work perspective by developing an understanding of places as objects characterized by location, materiality, function, and symbolic meaning and which can be changed through social‐symbolic work. Drawing from a longitudinal study of the ‘Empty Homes’ Programme in England, our analysis identifies an unfolding ...

Heavy‐duty conceptual engineering
Noûs, Volume 59, Issue 4, Page 902-920, December 2025.Abstract Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to ...

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.Die Adsorption von flüchtigen und sehr flüchtigen organischen Verbindungen ((V)VOCs) mithilfe von hypervernetzten Polymeren, deren chemische Funktionalitäten gezielt variiert wurden, wird untersucht. Durchbruchsexperimente mit Mehrkomponentengemischen zeigen, wie die Polymerchemie die Sorption unter trockenen und feuchten Bedingungen beeinflusst.

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.Der Einbau verschiedener Chalkogenatome (O, S, Se oder Te) in häufig verwendete Isochalkogenharnstoff‐Organokatalysatoren ermöglicht die Feinabstimmung ihrer Nucleophilie und Basizität. Kinetische und thermodynamische Deskriptoren für die molekularen Eigenschaften der Katalysatoren werden als Werkzeuge zur Vorhersage ihrer Effizienz eingeführt und in ...

Angewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.The adsorption of volatile and very volatile organic compounds ((V)VOCs) is investigated using hypercrosslinked polymers with varied chemical functionalities. Mixed‐analyte breakthrough experiments reveal how polymer chemistry governs sorption under dry and humid conditions. Amine‐functionalised networks outperform commercial benchmarks, offering broad

Angewandte Chemie International Edition, Volume 64, Issue 48, November 24, 2025.Incorporation of different chalcogen atoms allows for the fine‐tuning of nucleophilicity and basicity of commonly used isochalcogenourea organocatalyst scaffolds. Kinetic and thermodynamic descriptors for the molecular properties of the catalysts are introduced as tools to predict their efficiency and tested in acyl transfer and allenoate activation ...
