    Reviewing forgotten “Pre‐Linnaean” generic names validly published in the third volume of Diderot and d'Alembert's Encyclopédie in 1753
    (International Association for Plant Taxonomy, 2024-04)

    This paper presents a comprehensive review of previously overlooked names published in the third volume of the Encyclopédie by Diderot and d'Alembert in 1753. These names primarily originate from Tournefort's pre-Linnaean work, including textual copies of Tournefort's descriptions. We identified 21 names as having been validly published. Notably, among these are five generic names (Castanea, Chamaemelum, Chrysanthemoides, Citreum, Cydonia) wherein the taxonomic authorship shifts from Miller to Daubenton according to priority. Consequently, by our typifications, Miller's names from 1754 are later isonyms. Additionally, the generic name Chamaebuxus takes priority over Polygaloides. As a result, we propose a new combination, Chamaebuxus paucifolia and designate types for 31 generic names and isonyms: Caprifolium, Castanea, Chamaebuxus, Chamaecerasus, Chamaemelum, Chamaerhododendros, Chrysanthemoides, Cichorium, Cicuta, Cicutaria, Clandestina, Clymenum, Colocynthis, Citreum, Clematitis, Coa, Comaroides, Cydonia, Gramen, Scorpioides, and Sisarum, and lectotypes for two species names: Chamaebuxus paucifolia and Polygala uniflora.

    Brechas de género en la ciencia: un análisis de los proyectos de investigación de las Universidades radicadas en la Provincia de Buenos Aires

    Este trabajo analiza las brechas de género en la actividad de ciencia y tecnología (CyT) de las universidades de gestión pública (UUPP) radicadas en la Provincia de Buenos Aires (PBA). Se analiza la segregación ocupacional mediante la composición y roles de los equipos de investigación y la distribución de varones y mujeres entre áreas disciplinares. Se construyó una base de datos con información a nivel de integrantes y área disciplinar de los proyectos de investigación radicados en las UUPP de la PBA. La muestra incluye información sobre 2401 proyectos de investigación y 12310 personas (20 de 24 UUPP). Los resultados muestran la existencia de segregación vertical y horizontal en la CyT en las UUPP de la PBA. Las mujeres tienen menor probabilidad de dirigir proyectos de las ciencias exactas y naturales y en las ciencias agrarias e ingenierías, respecto de las ciencias sociales. La cantidad proporcional de mujeres en la muestra es 3 puntos porcentuales menor que la cantidad de mujeres que dirigen proyectos a nivel nacional. Esta diferencia aumenta cuando los equipos son dirigidos por varones. Destacamos la necesidad de seguir incorporando la perspectiva de género de manera transversal en la CyT para disminuir hasta erradicar las brechas sexo-genéricas.

    A 2-complex with contracting non-positive immersions and positive maximal irreducible curvature
    (European Mathematical Society, 2024-10)
    Blufstein, Martín Axel
    ;
    Minian, Elias Gabriel
    We prove that the 2-complex associated to the presentation ha; b j b; bab1a 2 i has contracting non-positive immersions and positive maximal irreducible curvature. This example shows that the contracting non-positive immersions property is not equivalent to the notion of non-positive irreducible curvature, answering a question raised by H. Wilton.

    Definition and demonstration in Aristotle, Posterior Analytics II 1-7
    (Editions Ousia, 2024-11)
    Mie, Fabian Gustavo
    Divisional definition is sometimes considered a key element in Aristotelian science since it seems to provide an account of species (or specific subjects), which could feature as a main principle of demonstration (Posterior Analytics II 13, 96b21-28; II 17, 99a22-23). Now, Aristotle must make clear which is actually the procedure to know species, since it cannot be demonstration. This is addressed in a preliminary, dialectical way in the rather neglected chapters II 3-7, which will be the focus of this paper. Against the common view, which sees these chapters as a rather confusing picture of the relationship between definition and demonstration – to be corrected (and for the most part discarded) from II 8 on –, I will argue that (i) these chapters manage to lay the foundations for distinguishing the logical procedure of division from deduction and demonstration (II 3-4); that (ii) II 5-6 (and 8) state that divisional definitions are not reached by deduction nor (unlike that of per se attributes) by demonstration; and finally that (iii) II 7 shows that division is necessary to know the existence (not just the essence) of specific subjects. All this proves to be a crucial prerequisite for Aristotle’s more positive theses (to be considered here in prospect only) about different kinds of definition (in II 8-10) and about division as the method for grasping explanatorily basic essential features (in II 13- 18).

    Proposal to conserve the name Molopospermum against Cicutaria (Apiaceae)
    (International Association for Plant Taxonomy, 2024-04)

    Molopospermum W.D.J. Koch (Apiaceae), is a monotypic genus, comprising M. peloponnesiacum (L.) W.D.J. Koch, an edible plant utilized in culinary practices in a similar manner to celery. This genus was originally segregated from Ligusticum by Koch (in Nova Acta Phys.-Med. Acad. Caes. Leop.-Carol. Nat. Cur. 12: 108. 1824) and is native to the southern mountainous regions of France, Italy, and Spain (Plants of the World Online, https://powo.science. kew.org/taxon/urn:lsid:ipni.org:names:844979-1, accessed 22 Jan 2024). Since its publication, the taxonomy and nomenclature of Molopospermum have remained reasonably stable. The only exception being that Otto Kuntze (Revis. Gen. Pl. 1: 266. 1891) adopted Cicutaria for Molopospermum and C. peloponnesiaca for its one species. [Kuntze adopted a 1735 (Linnaeus, Syst. Nat.) starting date for botanical nomenclature; Miller (Gard. Dict., ed. 2. 1737) had also adopted Cicutaria, but later (e.g., Miller, Gard. Dict. Abr., ed. 4. 1754) included it in Ligusticum. The current 1753 starting date was only established in the Vienna Rules (Briquet, Règles Int. Nomencl. Bot. 1906)]. The same generic name was published – but with different applications – as Cicutaria Heist. ex Fabr. (Enum.: 40. 1759) (≡ Conium L.) and as Cicutaria Moench (Meth. Suppl.: 32. 1802), nom. illeg., applying to elements of Molopospermum and Trinia, and in a more widespread usage by Lamarck (Fl. Franç. 3: 445. 1779) for what is now established as Cicuta L.
