Il mobbing questo (s)conosciuto
No full textNel volume viene affrontato il problema del MOBBING sotto quattro diversi angoli di visuale: quello sociologico, quello psicologico,quello giuridico-normativo e quello previdenziale. Si evidenzia da un lato la progressiva diffusione del fenomeno e dall'altro la carenza di legislazione e di protezione sociale a fronte di altri paesi europei che già hanno legiferato in materia
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Prove di lotta contro l’oidio del carciofo causato da Leveillula taurica.
No full textIn una prova triennale condotta in Sardegna contro l’oidio del carciofo, sono stati posti a
confronto penconazole, tebuconazole WG, tebuconazole SE ed azoxystrobin. I risultati
ottenuti dimostrano che tutti i prodotti saggiati sono in grado di contenere la malattia, ma con
differente efficacia. In generale, tebuconazole SE e penconazole hanno fornito i risultati
migliori, seguiti dall’azoxystrobin. Più ridotta l’efficacia di tebuconazole WG.In a 3-year trial carried out in Sardinia (Italy) against artichoke powdery mildew,
penconazole, tebuconazole WG, tebuconazole SE and azoxystrobin were evaluated. All
fungicides tested were able to control the disease, but in a different way as regards
effectiveness. Tebuconazole SE and penconazole gave the best results, followed by
azoxystrobin. The efficacy of tebuconazole WG was lowe
Lingual schwannoma in pediatric patients
No full textWe present the case of a 15-year-old boy who presented to our emergency department because of a soft lesion growing on the back of his tongue. On examination, a vegetant mass on the posteromidline lingual part of the body of the tongue was noticed: it was not painful, even if the boy reported discomfort because of its size; there was no bleeding or signs of infection. The magnetic resonance imaging showed the lesion as trilobated and capsulated, but was not diriment to define a diagnosis; excisional biopsy was performed under general anesthesia, and the mass was identified as a schwannoma. Schwannoma, or neurilemmoma, is a benign tumor originating from Schwann cells of the nerve sheath surrounding peripheral nerves. It is slow-growing, usually solitary, and encapsulated. Intraoral schwannomas are rare and account for 1% of lesions of the head and neck region. There is no sex predilection. The symptoms depend on size and location of the tumor. Recurrence is rare after complete surgical resection. The present study aimed to retrospectively describe our experience with a case of neurilemmoma of the tongue presenting in childhood, the diagnostic methods used, the surgical decision, and the treatment outcome and to analyze the data and review the literature available on this type of tumor. The etiology, clinical presentation, differential diagnosis, and management are discussed
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
