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
Recovery from vegetative state of patients with a severe brain injury: a 4-year real-practice prospective cohort study
No full textPatients who have suffered severe traumatic or nontraumatic brain injuries can show a progressive recovery, transitioning through a range of clinical conditions. They may progress from coma to a vegetative state (VS) and/or a minimally conscious state (MCS). A longer duration of the VS is known to be related to a lower probability of emergence from it; furthermore, the literature seems to lack evidence of late improvements in these patients. This real-practice prospective cohort study was conducted in inpatients in a VS following a severe brain injury, consecutively admitted to a vegetative state unit (VSU). The aim of the study was to assess their recovery in order to identify variables that might increase the probability of a VS patient transitioning to MCS. Rehabilitation treatment included passive joint mobilisation and helping/placing patients into an upright sitting position on a tilt table. All the patients underwent a specific assessment protocol every month to identify any emergence, however late, from the VS. Over a 4-year period, 194 patients suffering sequelae of a severe brain injury, consecutively seen, had an initial Glasgow Coma Scale score ≤ 8. Of these, 63 (32.5%) were in a VS, 84 (43.3%) in a MCS, and 47 (24.2%) in a coma; of the 63 patients admitted in a VS, 49 (57.1% males and 42.9% females, mean age 25.34 ± 19.12 years) were transferred to a specialist VSU and put on a slow-to-recover brain injury programme. Ten of these 49 patients were still in a VS after 36 months; of these 10, 3 recovered consciousness, transitioning to a MCS, 2 died, and 5 remained in a VS during the last 12 months of the observation. Univariate analysis identified male sex, youth, a shorter time from onset of the VS, diffuse brain injury, and the presence of status epilepticus as variables increasing the likelihood of transition to a MCS. Long-term monitoring of patients with chronic disorders of consciousness should be adequately implemented in order to optimise their access to rehabilitation services
Sarcopenic dysphagia: a narrative review
No full textSarcopenia and dysphagia are two disabling conditions sharing several etiological risk factors and their coexistence has captured the scientific interest in the last few years. Malnutrition, aging and inactivity have been considered the main risk factors underlying sarcopenia and dysphagia; however they are not sufficient to fully elucidate the patho-physiological mechanisms underpinning these two conditions. Recent studies showed that sarcopenia could be a main cause of dysphagia and similarly dysphagia might directly induce or worsen sarcopenia. Indeed, these two pathological conditions are widely considered independent risk factors for each other. Recently, the term "sarcopenic dysphagia" was introduced to identify a condition characterized by the loss of muscle mass and strength of deglutition musculature, with consequent impairment in swallowing function. However precise diagnostic criteria and treatment indications are lacking. Further evidence is needed to define unequivocal diagnostic criteria and the role of a multi-disciplinary treatment, also known as "rehabilitation nutrition", in the management of sarcopenic dysphagia
Evaluation of the safety profile of intra-articular treatment with Oxygen-Ozone therapy in knee arthrosis: controlled randomized study
No full textBuccal hemineglect: is it useful to evaluate the differences between the two halves of the oral cavity for the multidisciplinary rehabilitative management of right brain stroke survivors? A cross-sectional study
No full textBackground: Unilateral spatial neglect (USN) is the most frequent cognitive impairment after right brain stroke, characterized by inattention to sensory stimuli in the opposite hemispace. It has been recently hypothesized a novel condition defined as "buccal hemineglect," a particular form of USN with detrimental oral effects on right stroke survivors.Objective: The aim of our study was to compare the oral hygiene between the two halves of oral cavity in right stroke survivors.Methods: In this cross-sectional study, we assessed a cohort of right-handed subjects affected by right brain stroke with left hemiparesis, divided into two groups based on the presence of USN. We administered an evaluation protocol, including New Method of Plaque Scoring, Oral Hygiene Index (OHI), Gingival Index, Oral Food Debris Index, and Winkel Tongue Coating Index (WTCI). All outcome measures were assessed in the entire cohort considering both left and right halves of oral cavity.Results: Of the 21 patients included (mean aged 64.19 ± 7.60 years), the 14 affected by USN (mean aged 64.50 ± 8.06 years) had significantly worse values in all outcome measures in the left oral cavity compared to the right one (P < .01). On the other hand, the seven patients not affected by USN (mean aged 63.57 ± 7.16 years) showed statistically significant differences only in OHI (P = .03) and WTCI (P = .03).Conclusion: Hygiene of left oral cavity was significantly worse than contralateral in right brain stroke survivors with USN. This study highlights the need to develop an adequate oral rehabilitation program in these patients
