Significance of an integrated rehabilitative approach: case report of a child with cortical visual impairment in cerebral palsy
No full textMuscle eye brain disease: case report
No full textThe objective of this presentation is to describe a case of an
Italian child with muscle eye brain (MEB) disease. It is known
from the literature that MEB is a rare congenital muscular
dystrophy, which until now has been described mostly in
Northern European countries, especially Finland. It is characterized
by hypotonia, muscular weakness, and learning
disability. The visual impairment consists in severe myopia,
retinal degeneration, and optic atrophy. MRI shows brain
malformation of a cobblestone-like cortex and hypoplasic
pons; the visual evoked potentials are significantly high. A
child, diagnosed with Santavuori disease, presented at our
centre when she was 7 months old. The baby was very hypotonic
and she was not rolling, nor sitting, and was not interested
in anything except in her hands and feet. Ocular
findings showed a retinal detachment in the left eye and a
corioretinic atrophy in the right one. A rehabilitative project
commenced which focused on sensory (especially visual)
functions, started. The aim was to integrate sensory and
motor skills. In these two years, despite the slowness of the
progresses, the child has made quite a few improvements.
She is now 33 months old and is able to go on all fours and to
make a few steps alone, especially to reach her mother. She
now appears more motivated to explore the environment to
look for her preferred toys; she also understands and
responds to simple requests made by the therapist. She is
able to organize the first simple constructive movements of
the hands, even if she still prefers to play on the light-box.
She is increasing in using both hands and recently started to
play with a doll. She also began to show interest in images on
an adapted screen of a personal computer and recognized an
image imitating the movement on the screen. In conclusion,
even if psychomotor delay is still present, we think that early
rehabilitation is important to help the child have the best
quality of life compatible with the disease
Visual assesment in multidisabled infants
No full textThe importance of an early visual assessment during infancy is due to the main role of vision in comprehensive development and to the correlation between early rehabilitative intervention and progress in visual function. More than 50% of children with low vision have also other impairments, therefore the visual assessment requires a multidisciplinary approach. Here we propose for discussion and comparison a detailed protocol we use at the Robert Hollman Foundation for multi-disabled infants from birth to 3 years old. This protocol is functional-diagnostic with the aim of individuating visually impaired children to give them the chance to start an early rehabilitation programme. It is composed by a diagnostic neuropthalmological assessment, which is done at the Centro Regionale per Ipovisione of Padua Hospital, and by a functional/rehabilitative assessment, which is done at the Robert Hollman Foundation. Particular importance is given to create the comprehensive conditions to enable the child to give his/her best performance during the assessment. In fact it has already been shown how the environmental conditions and the kind of stimuli are determinant in permitting an accurate evaluation of the visual situation of the infant. Moreover, in multi-disabled children, aspects like postural and non-verbal signs become fundamental in the visual assessment
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
