Fenologia e dannosità di Heliothrips haemorrhoidalis (Bouché) (Thysanoptera Thripidae) nell'Italia nord-orientale
Biologia di Ceroplastes ceriferus (Fabricius) (Hemiptera, Coccoidea) e possibilità di controllo
Vengono riportati distribuzione italiana, piante ospiti e ciclo biologico di C. ceriferus, cocciniglia esotica dannosa a piante ornamentali, segnalata per l’Italia nel 2001. Per la sua potenziale dannosità a ornamentali e fruttiferi, la specie è stata inserita nella EPPO Alert List nel 2003. La specie risulta attualmente acclimatata in tre regioni (Lombardia, Veneto, Emilia Romagna). Compie una generazione annuale con svernamento sostenuto da femmine adulte. La fenologia dei diversi stadi è stata studiata per due anni consecutivi allo scopo di individuare il periodo di presenza sulla pianta dei diversi stadi di sviluppo. Prove di lotta chimica mediante impiego di tre diversi principi attivi hanno dato buoni risultati
Prime indicazioni sull’efficacia di alcuni insetticidi nel controllo delle infestazioni di Acizzia jamatonica (Kuwayama), psilla dell’albizzia
Prove di lotta contro Ceratocystis fimbriata f.sp.platani mediante iniezioni di fitofarmaci al tronco
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
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
