Escala de detección de olvidos. Una herramienta de rastrillaje para el deterioro cognitivo leve
Full text linkEn los últimos años han incrementado las consultas por fallas de memoria, dado que ha aumentado la expectativa de vida.
La prevalencia de trastornos mnésicos en la edad adulta, requiere instrumentos de rastrillaje sensibles, específicos y de
rápida administración para la detección del deterioro cognitivo. El fin de dichos instrumentos es que puedan ser
administrados por médicos generales y aún otros profesionales de la salud siendo de fácil interpretación, para la
discriminación entre olvidos patológicos y olvidos asociados al envejecimiento normal. Permitiendo la derivación o el
estudio más exhaustivo de aquellos sujetos que presenten indicios de deterioro cognitivo. Objetivo: Establecer la validación
de la Escala de Detección de Olvidos (EDO-10), un breve cuestionario para ser completado por el informante del paciente,
que sirve detectar sujetos con deterioro cognitivo leve. Es un instrumento que puede ser administrado de manera sencilla y
posee la ventaja de no necesitar la presencia del paciente. El cuestionario posee 10 preguntas de rápida respuesta, para ser
contestadas por SI/NO. Método: Se evaluaron 44 pacientes con deterioro cognitivo leve y 40 controles normales apareados
por edad y nivel educacional. Se administró la EDO-10 y una Batería Neuropsicológica extensa. Resultados: Los pacientes
se diferenciaron significativamente de los controles en la EDO (p < .001), el MMSE (p < .001), en la Lista de Rey (p <
.001) y el CDR (p < .001). La EDO-10 presentó una significativa correlación con el CDR (r = .524; p < .001), con RAVLT
(r = -.551; p < .001) y con el FAQ (r = .705; p < .001). El área bajo la curva ROC de la escala fue 0.835 y con un puntaje
de corte de 4 tuvo una sensibilidad 0.75 y una especificidad de 0.78 para detectar deterioro cognitivo leve. Conclusiones:
La EDO-10 es un instrumento de rápida y fácil administración con adecuadas propiedades psicométricas para ser usado en
la clínica, para la detección de DCL.Fil: Cervino, Cecilia. Fleni. Departamento de Neurología. Servicio de Neurología Cognitiva, Neuropsicología y Neuropsiquiatría.

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
Utility of a spanish version of three words-three shapes test to detect memory impairment in primary progressive aphasia
No full textIntroduction: Three Words-Three Shapes (3W3S) is a bedside test that assesses verbal and non-verbal memory and has proven useful in staging memory decline in amnestic disorders and primary progressive aphasia. Given its simple structure, the 3W3S can be easily adapted to other languages maintaining the original shapes and only modifying the words. We aim to validate a Spanish version of the 3W3S test and establish whether memory loss patterns present in amnesic disorders associated with Alzheimer's etiology and PPA were correctly characterized. Method: The translation and adaptation of the 3W3S were performed according to standardized guidelines and applied to a cohort of patients with Dementia of Alzheimer's type (DAT = 20), mild cognitive impairment (aMCI= 20), primary progressive aphasia (PPA = 20), and healthy controls (HC = 20). Results: In verbal memory performance, PPA patients' score was lower than that of MCI and HC and similar to DAT's in the effortless encoding (p < 0.001), delayed recall (p < 0.001), and recognition (p < 0.012). For non-verbal performance, PPA patients performed better than DAT and similar to HC and MCI subjects (p < 0.001). Conclusions: Results show good applicability of 3W3S to determine memory function in PPA patients, independently from language ability. Visual and verbal components of memory are dissociated in PPA.Fil: Calandri, Ismael Luis. Fundación para la Lucha contra las Enfermedades Neurológicas de la Infancia; ArgentinaFil: Crivelli, Lucia.

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
