Emotional dysregulation, affective status and personality traits in a sample of migraine patients
Full text linkBackground: Several studies hypothesize emotional dysregulation in subjects with migraine related to a generalized hyperexcitability both to sensory and emotional stimuli, involving the cortical-limbic system. The aim of the study was to investigate Emotional Reactivity by means of the International Affective Picture System (IAPS), in a sample of migraineurs in order to evaluate differences between the patients and a healthy reference group and the relationships with clinical evaluations: personality traits, psychopathological symptoms, empathy, affective status, coping and resilience strategy and with the severity of the headache disorder. Methods Twenty patients with migraine (14 females, 6 males) and fifteen healthy subjects (9 females, 6 males) matched for age and gender were recruited. Emotional Reactivity was tested using International Affective Picture System (IAPS); Clinical Global Impression evaluated behavioral disturbances. Clinical evaluation, by using the Zung Self-Rating Anxiety Scale, the Beck Depression Inventory II, the Empathy Quotient, the brief TEMPS-M temperament questionnaire, the Millon Clinical Multiaxial Inventory III, the Symptom Check List 90, the Brief Cope, the Resilience Scale 14 and the Migraine Disability Assessment, was performed. Results: The mean arousal ratings of the clinical group were significantly higher than those of the control group for unpleasant and socially unpleasant pictures. The arousal scores of socially unpleasant pictures showed numerous significant correlations with psychometric scores, since higher arousal is associated with higher migraine disability. Valence to unpleasant images was similarly related to migraine disability, while arousal was inversely related to the Brief Cope score. Conclusions: The association between personality traits and emotional dysregulation in migraine patients is worth of attention because it could represent the cause of an increased susceptibility to many negative stimuli, may worsen the course and prognosis of the headache disorder and may amplify the vulnerability to psychopathology
Facial functional outcome in monitored versus not-monitored patients in vestibular schwannomas surgery.
Full text linkOBJECTIVE:
Even though advances in surgical techniques have improved facial nerve outcomes, functional preservation is still an issue because injury to the facial nerve has significant physical and psychological consequences for the patient. We retrospectively review our data in VS surgery to compare the facial outcome in intraoperative facial monitored versus not-monitored patients.
MATERIALS AND METHODS:
51 consecutive patients with unilateral vestibular schwannoma in the period from 2005 to 2010 were treated in our Institution. In according to the type of neurophysiological tool used during surgical procedures, two patients groups were identified: Group 1 (facial stimulator only) and Group 2 (stimulator and facial monitoring). Statistical comparison of the two groups was made with the t- test, and facial function results were evaluated with the Fisher's exact test.
RESULTS:
In the Group 1, of the 22 patients with anatomically preserved facial nerves, 3 (13.6%) showed excellent facial nerve function, 14 (63.6%) showed intermediate function, and 5 (22.7%) showed poor function. In the Group 2, all the 27 patients got anatomically preserved facial nerves, and 18 (66.7%) showed excellent facial nerve function, 9 (33.3%) showed intermediate function, and no one showed poor function.
CONCLUSIONS:
We found that retrosigmoid approach associated with continuous EMG facial monitoring combined with the use of bipolar stimulation is a safe and effective treatment for vestibular schwannomas

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
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
