    Vito Volterra (1860-1940) was one of the most famous representatives of Italian science in his day. Angelo Guerragio and Giovanni Paolini analyze Volterra’s most important contributions to mathematics and their applications, as well as his outstanding organizational achievements in scientific policy. Volterra was one of the founding fathers of functional analysis and the author of fundamental contributions in the field of integral equations, elasticity theory and population dynamics (Lotka-Volterra model). He delivered keynote lectures on the occasion of the International Congresses of Mathematicians held in Paris (1900), Rome (1908), Strasbourg (1920) and Bologna (1928). He became involved in the scientific development in united Italy and was appointed senator of the kingdom in 1905. One of his numerous non-mathematical activities was founding the National Research Council (Consiglio Nazionale delle Ricerche, CNR). During the First World War he was active in military research. After the war he took a clear stand against fascism, which was the starting point for his exclusion. In 1926 he resigned as president of the world famous Accademia Nazionale dei Lincei and was later on excluded from the academy. In 1931 he was one of the few university lecturers who denied to swear an oath of allegiance to the fascistic regime. In 1938 he suffered from the impact of the racial laws. The authors draw a comprehensive picture of Vito Volterra, both as a great mathematician and an organizer of science

    Per più di mezzo secolo, il matematico Vito Volterra (1860-1940) è stato la figura più rappresentativa della scienza italiana. Gli autori ricostruiscono i suoi più importanti contributi allo sviluppo della scienza e delle sue istituzioni, in Italia e nel mondo: lo sviluppo dell'analisi funzionale, lo studio della dinamica delle popolazioni con il modello Lotka-Volterra, l'insegnamento universitario, la fondazione del CNR. Nel dopoguerra Volterra non prova alcuna simpatia per il fascismo. Comincia così la sua emarginazione. Nel 1926 è allontanato dalle presidenze del CNR e dell'Accademia dei Lincei. Nel 1931 è uno dei pochissimi docenti universitari a rifiutare il giuramento di fedeltà al regime. Nel 1938 le leggi razziali lo colpiscono in quanto ebreo. Un grande matematico e un manager scientifico di altissimo livello, che sa rinunciare al potere per coerenza con la propria storia personale e i propri principi.For more than half a century, the mathematician Vito Volterra (1860-1940) was the most representative figure of Italian science.

After the war, Volterra feels no sympathy for fascism. Thus begins his exclusion. In 1926 he was turned away by the Presidencies of the CNR and the Accademia dei Lincei. In 1931 he was one of the few academics to refuse the oath of loyalty to the regime. In 1938 the racial laws as they affect the jew. A great mathematician and a manager of a very high scientific level, who knows how to give up power for consistency with his own personal history and principles

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    La psicogenesi dei concetti matematici

    Nella pubblicazioni delle voci di matematica redatte per l'Enciclopedia Italiana, Federico Enriques rivela un grande interesse per gli studi psicologici; in particolare, si rivolge alla psicofisiologia wundtiana ed helmholtziana per definire il problema della strutturazione della conoscenza scientifica. Enriques propone un'originale interpretazione relativa alla genesi psicologica dei concetti matematici
