MANLIO GRAZIANO, Geopolitica. Orientarsi nel grande disordine internazionale, Bologna, Mulino, 2019; BARBARA LOYER, Geopolitica. Metodi e concetti, Novara, UTET, 2021
No full textLa recensione esamina due libri recenti dedicati alla geopolitica. Graziano (2019) adotta un approccio internazionalista, equiparando il fattore geografico ad altri “vincoli” all’azione politica. Loyer (2021), nella tradizione francese inaugurata da Yves Lacoste, mantiene un approccio geografico multiscalare e orientato all’analisi dei conflitti territoriali. Si conclude evidenziando che il rilancio di una geopolitica accademica in Italia non può esimersi da un confronto con gli avanzamenti maturati dalla disciplina in altri Paesi
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
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
L’integrazione dei trattamenti nel disturbo ossessivo-compulsivo: conoscenze attuali e prospettive future.
No full textRIASSUNTO. Scopo. Il trattamento del disturbo ossessivo-compulsivo (DOC) prevede l’utilizzo di inibitori della ricaptazione della serotonina (IRS) e della terapia cognitivo-comportamentale (TCC).La revisione si propone di discutere se:
a) la terapia combinata ab initio sia una strategia più efficace rispetto alle singole monoterapie; e b) la terapia sequenziale sia efficace nel trattare pazientiresponder con sintomiresidui, e nell’indurre una risposta clinica nei non responder.Metodi. Sono stati utilizzati gli archivi elettronici MEDLINE/PubMed e libri di testo scientifici prendendo in considerazione
tutti gli studi clinici controllati randomizzati scritti in inglese.In assenza di questi,sono stati considerati gli studi naturalistici in aperto. Sono stati revisionati 9 studi randomizzati e/o controllati riguardo l’utilizzo della terapia combinata ab initio versusTCC da sola; 6 tra trattamento combinato e IRS da soli. Per il trattamento sequenziale,sono stati considerati 2
studi con pazienti responder e 7 con campioni di pazienti non responder. Risultati. Dei 9 studi, 7 non ne hanno rilevato
alcun vantaggio rispetto alla solaTCC, 1 ha evidenziato una maggiore efficacia in pazienti bambini e adolescenti e 1 in pazientiseveramente depressi.Rispetto alla sola farmacoterapia, 4 lavori non hanno rilevato una maggiore efficacia della terapia combinata, mentre 2 studi erano positivi.Tutti glistudisul trattamento sequenziale erano positivi. Discussione. La
combinazione ab initio non rappresenta una valida strategia di trattamento in prima istanza nel DOC, a eccezione di pazienti adultiseveramente depressi e pazienti bambini o adolescenti.Al contrario,l’integrazione sequenziale delle due strategie di prima linea è efficace sia nel portare a remissione completa i pazienti con sintomiresiduisia nel determinare una
risposta clinica nei pazienti resistenti
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Combined treatments in obsessive-compulsive disorder: current knowledge and future prospects
No full textSerotonin reuptake inhibitors (SRIs) and/or cognitive-behavioral psychotherapy (CBT) are first-line treatments for obsessive-compulsive disorder (OCD). The study discuss whether: a) combining both treatments ab initio is more effective than either monotherapy alone; and b) a sequential treatment is effective both in responder and non responder patients.
Have been carried out a search on Medline/PubMed database, selecting clinical randomized controlled studies in English. Have been examined 9 randomized controlled studies where combined treatment ab initio was compared to CBT alone, and 6 where combination treatment was compared to SRI alone. No controlled studies were found for sequential treatments in OCD. Have been then examined naturalistic studies, 2 including responder patients and 7 including non responder patients.
Of the 9 studies, 7 didn't find any additional benefit of combining treatments as compared to CBT alone; in 1 study the combination strategy resulted more effective than CBT alone in children and adolescents, and in another in severely depressed adult patients with OCD. As compared to SRIs alone, combining treatments was not more effective in 4 studies, while in 2 studies it was more effective. All studies concerning sequential treatments found evidence of efficacy of this strategy.
Combining ab initio CBT and SRI has not been found to be clearly superior of either therapy alone, except for patients with severe depression and for children and adolescents. On the contrary, a sequential strategy may be used successfully both to treat residual symptoms in responders and to determine clinical response in resistant patients
