Potenziali uditivi evocati del tronco in bambini normoudenti con turbe del linguaggio
No full textThe auditory brainstem responses (ABR) of 57 normally hearing children (age 1-6) suffering from a retarded language development were evaluated. Thirtytwo out of 57 children were suffering from previous diagnosed pathologies (CNS lesions, perinatal, congenital syndrom), 27 had a psychomotor retard. ABR was evaluated in terms of inter-peack I-V latency and V/I amplitude ratio. While the amplitude parameters were normal, 40% of cases showed I-V intervals exceeding the normal boundaries. These findings did not correlate either to pathology nor to psychomotor retard. The I-V intervals showed a bimodal distribution troughout the four age subgroups the children population had been subdivided, with a first peack corresponding to the normal mode, and a second one above the normal limit. This latter approximated the normal range of I-V interval in the age subgroup above 4 years. Assuming the I-V intervals changes as index of the maturation processs in the brainstem auditory pathway, our results seem to indicate that the retarded language development may be frequently associated to a delay in CNS maturation
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
COVID-19 in school settings: webinar aimed at both teachers and educators
No full textIn the COVID-19 era, we designed the webinar "COVID-19: instructions for use" with the aim of providing clear and actionable information to school staff about the characteristics of the disease, the preventive measures to adopt and the path for early detection and control of COVID-19 in primary schools of Modena province
A lightweight linked data implementation for modeling the Web of Things
No full textIn recent years, common-use devices' equipment has seen a leap transition in terms of shipped technology, introducing the so called 'smart things' to the consumer market. To take full advantage of opportunities arising from connectivity, smart things approached the application realm bringing the novel Web of Things vision to life. In this paper, we propose an approach for modeling and implementing the Web of Things for a Smart City environment that relies on a lightweight implementation of Linked Data. We represent a smart thing as a graph of granular and individually addressable information pieces called IDN-Document. IDN-Documents are structured web resources that can be aggregated, reused and combined to build collaboration oriented services. IDN-Documents can be managed by the InterDataNet (IDN) middleware, which allows to easily publish and handling resources on the web by leveraging the Linked Data and Representational State Transfer paradigms. We also provide a tool suite for supporting developers with easy-to-use tools in designing and developing web applications according to our Web of Things implementation approach. These technologies are currently under experimentation in the real smart city of Santander, Spain, in the context of the SmartSantader European project
