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
Peripheral neuropathy in styrene-exposed workers
Full text linkBackground The toxicity of styrene on the peripheral nervous system is still debated. Cases The paper presents two cases of peripheral sensorimotor neuropathy in styrene-exposed workers. Exposure, evaluated by biological monitoring, ranged between 100 and 150% of the current limits proposed by the American Conference of Governmental Industrial Hygienists (ACGM). The subjects complained of leg weakness and numbness, cramps, and paresthesia. Electrophysiology revealed a moderate peripheral sensorimotor neuropathy of a demyelinating type. Color-vision testing showed a subclinical deficit. Common inherited and acquired causes of peripheral neuropathy and dyschromatopsia other than styrene were ruled out by personal history, medical examination, laboratory data, and chest X-ray. Conclusions The results suggest that long-term occupational exposure to environmental levels of styrene that are equal, or slightly above, the ACGM limits can induce a clinical form of peripheral neuropathy and a subclinical impairment of color vision. As a consequence, a careful reappraisal of the real preventive meaning of the current ACGM occupational limit for styrene, at least on an individual basis, is needed

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
Le indagini palinologiche
No full textNell’ambito degli studi interdisciplinari previsti per ottenere maggiori informazioni sull’icona bizantina, è stato programmato il campionamento palinologico e il successivo studio di alcuni campioni per rilevare l’eventuale presenza di pollini e, di conseguenza, poter valutare la componente vegetazionale - ambientale mettendo in evidenza le probabili relazioni esistenti con l’azione e l’attività dell’uomo. Le analisi effettuate hanno permesso di evidenziare la presenza di un apprezzabile contenuto pollinico, particolarmente nel campione prelevato dall’orditura del tessuto nella parte superiore dell’icona, condizione indispensabile per fornire indicazioni relative alla vegetazione che ha prodotto una determinata pioggia pollinica. Sulla base dei reperti rinvenuti, la componente vegetale emersa dagli spettri risulta essere costituita da un buon numero di taxa e, considerando la loro specificità, si può dire che l’icona ha registrato nelle aree circostanti i luoghi in cui si è trovava la presenza di una discreta vegetazione arborea caratterizzata da due distinti gruppi di piante: quelle tipiche del piano basale, rappresentate dal querceto misto e, in sottordine, quelle caratteristiche della vegetazione tipica delle zone mediterranee. In particolare il querceto, presente con valori apprezzabili, indica la permanenza dell’icona in zone tipiche del piano basale, come quello che circonda la città di Venezia, dove l’icona risulta essere stata esposta per alcuni secoli e quello di Treviso, dove l’icona è tuttora custodita. La presenza, in sottordine, di specie tipiche della fascia mediterranea, quali Olivo, Leccio, Cisto, potrebbero invece indicare il soggiorno e/o il passaggio dell’icona per paesi del bacino del Mediterraneo e, potrebbe quindi avvalorare l’ipotesi della provenienza dell’icona da zone del vicino oriente. Si documenta inoltre una discreta concentrazione di pollini appartenenti alle famiglie delle Liliacee e delle Asteroidee, famiglie a cui appartengono numerose piante da fiore come l’astro, l’iris, ecc.; questi pollini potrebbero provenire da offerte votive di tipo floreale fatte all’immagine sacra rappresentata nell’icona.
La rilevante concentrazione di specie antropiche indica che l’icona è stata esposta per periodi prolungati in aree caratterizzate da una forte attività legata all’uomo, in particolare l’abbondante percentuale di pollini di cereali (grano, orzo segale) indica un’intensa attività agricola collegata alla loro coltivazione; probabilmente la presenza dei cereali potrebbe testimoniare l’esistenza, nelle vicinanze del luogo di esposizione dell’icona, di edifici in cui essi venivano stoccati per essere lavorati o venduti. Un’ipotesi suggestiva potrebbe essere invece quella che l’icona durante i suoi numerosi spostamenti sia stata trasportata insieme a carichi di cereali.
Infine, il rinvenimento di reperti pollinici di numerose piante da frutto (Gelso nero, Noce, diversi tipi di Pruno, ecc.) e di piante ornamentali (Platano, Tasso, ecc.) indica rispettivamente la presenza di orti e di giardini o viali alberati nelle vicinanze dell’ambiente in cui l’icona è stata custodita
