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
Ictal and peri-ictal cardiorespiratory abnormalities in paediatric seizures: possible relation with SUDEP?
No full textEcological and behavioral drivers of supplemental feeding use by roe deer Capreolus capreolus in a peri-urban context
Full text linkWinter supplemental feeding of ungulates potentially alters their use of resources and
ecological interactions, yet relatively little is known about the patterns of feeding sites use by target
populations. We used camera traps to continuously monitor winter and spring feeding site use in a
roe deer population living in a peri-urban area in Northern Italy. We combined circular statistics with
generalized additive and linear mixed models to analyze the diel and seasonal pattern of roe deer
visits to feeding sites, and the behavioral drivers influencing visit duration. Roe deer visits peaked at
dawn and dusk, and decreased from winter to spring when vegetation regrows and temperature
increases. Roe deer mostly visited feeding sites solitarily; when this was not the case, they stayed
longer at the site, especially when conspecifics were eating, but maintained a bimodal diel pattern
of visits. These results support an opportunistic use of feeding sites, following seasonal cycles and
the roe deer circadian clock. Yet, the attractiveness of these artificial resources has the potential to
alter intra-specific relationships, as competition for their use induces gatherings and may extend the
contact time between individuals, with potential behavioral and epidemiological consequences
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
Delayed appearance of interictal EEG abnormalities in early onset childhood epilepsy with occipital paroxysms.
No full textChildhood epilepsy with occipital paroxysms is an age-related idiopathic focal epilepsy. Occipital EEG paroxysms are considered necessary for diagnosis. We carried out a close clinical and EEG follow-up (range, 2-12 years; mean, 6 years 7 months; median, 7 years) in 24 patients (age range, 4-19 years; mean, 11 years 8 months; median, 11 years). In five children with early seizure onset and particularly benign prognosis without any treatment, EEG abnormalities appeared 3-10 months after the first seizure. Four of them exhibited the ictal pattern of versive seizures with vomiting. Our findings confirm that in the early idiopathic focal seizure disorders, interictal EEG abnormalities may be lacking at the beginning of the disorder
