Uno studio pilota per la rilevazione della velocità di lettura in modalità silente: implicazioni per la valutazione di adolescenti e adulti con dislessia
No full textComprendere i meccanismi che sottendono la velocità di lettura in modalità silente (silent reading fluency – SRF) è di primaria importanza, considerato che la lettura silente è la principale modalità di lettura degli adolescenti e degli adulti. Abbiamo valutato le abilità di lettura in modalità silente di 68 soggetti adulti di età compresa tra i 18 e i 48 anni: 24 erano normolettori con alto livello di scolarizzazione (diploma di laurea; media degli anni di scuola 17,45, DS = ,93); 22 normolettori con un più basso livello di scolarizzazione (diploma di scuola superiore; media degli anni di scuola 12,95, DS = ,65); 22 lettori dislessici (con almeno il diploma di scuola superiore; media degli anni di scuola 12,59, DS = 1,71). Tutti i soggetti leggevano più velocemente nella modalità silente che in quella ad alta voce. Tuttavia, tra i lettori dislessici, si è osservato un minore incremento percentuale della velocità di lettura che è stato di appena il 25% contro il 62% dei normolettori con un livello di scolarizzazione più elevato e del 51% dei normolettori con un più basso livello di scolarizzazione. La presente ricerca suggerisce che i disturbi specifici di lettura sono interferenti con la comune capacità di incrementare la velocità di lettura in modalità silente
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
Should we screen for cognitive decline and dementia?
No full textDue to increased life expectancy, the prevalence of cognitive decline related to neurodegenerative diseases and to non-neurological conditions is increasing in western countries. As with other diseases, the burden might be reduced through personalized interventions delivered at early stages of the disease. Thus, there is an increasing demand, from both social and healthcare systems, for instruments and strategies to recognize cognitive decline, and possibly distinguish the precursor of serious neurodegeneration from "benign senile forgetfulness" or the temporary consequences of illness or trauma. However, this goal faces both technical and ethical issues. In this article we deal with the following: (i) re-definition of cognitive decline and its relationship with frailty definitions, starting from the recent work of international consensus groups for presymptomatic Alzheimer disease recognition; (ii) ethical problems concerning anonymous and personalized cognitive screening and the need for appropriate counselling; (iii) the need for more sensitive and specific tools to detect and distinguish pathological levels of cognitive decline and delineate the contribution of non-pathological decline to accumulated frailty impacts and (iv) the potential of the language domain and spontaneous speech analyses
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
