Full text linkAfter the outbreak of Covid-19, galleries and museums have been experimenting with new ways to engage a potential audience remotely. This study focuses on the level of engagement of virtual tours in museums looking at the representation of architectural space, representation artifacts, and ease of use as possible correlated factors. A sample group of eighty early-career experts in the field of art, architecture, or design assessed their visit to the archaeological museum of Troya Müzesi in Çanakkale, Turkey; half of the participants resided in Turkey, while the other half in Italy. This paper has addressed the following research questions with an online multi-level study: how is the online exhibition platform evaluated by its audience? Can regular employment of virtual tours engage new visitors in the long term? Is the representation of a museum, in the form of a virtual twin, an adequate surrogate that creates an immersive visiting experience
Intervertebral disc calcification in childhood: Case report and review of relevant literature
Full text linkThe authors report the case of a 10-year-old girl with intervertebral disc calcifications from the levels C6/C7 to Th1/Th2, presenting with a herniated calcified intervertebral disc at the C7/Th1 level, causing spinal cord compression with subsequent progressive paresis and sensory loss of her left leg. After anterior cervical discectomy and fusion the neurological deficits completely resolved within 2 weeks. It can be concluded that calcification of an intervertebral disc is a rare syndrome in childhood, causing progressive neurological deficit only in a few reported cases. Although the treatment of choice is conservative, surgery is required in patients who develop progressive neurological deficit
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
Convexal subarachnoid hemorrhage and acute ischemic stroke: a border zone matter?
Full text linkBackground Convexal subarachnoid hemorrhage (c-SAH) is an infrequent condition with variable causes. c-SAH concomitant
to acute ischemic stroke (AIS) is even less frequent, and the relationship between the two conditions remains unclear.
Methods Between January 2016 and January 2018, we treated four patients who were referred to our stroke unit with ischemic
stroke and concomitant nontraumatic c-SAH. The patients underwent an extensive diagnostic workup, including digital subtraction angiography (DSA).
Results All four patients developed acute focal neurological symptoms with restricted MRI diffusion in congruent areas. In three of
the patients, infarcts were in a border zone between the main cerebral arteries and c-SAH was nearby. The fourth patient showed a
small cortical infarct, and c-SAH was in a border zone territory of the contralateral hemisphere. An embolic source was discovered or
strongly suspected in all cases. One patient was treated with intravenous thrombolysis, but this treatment was not related to c-SAH.
None of the four patients showed microbleeds or further cortical siderosis, thus excluding cerebral amyloid angiopathy. In addition,
DSA did not show signs of vasculitis, reversible cerebral vasoconstriction syndrome, or intracranial arterial dissection.
Conclusions We proposed the embolism or hemodynamic changes of the border zone arterioles as a unifying pathogenetic
hypothesis of coexisting c-SAH and AIS
Effetti psicologici della taurina in epilettici con crisi parziali a semeiologia complessa
No full textSono state studiate mediante batteria di test neuropsicologici le modificazioni psicologiche indotte dalla taurina in 10 pazienti con epilessia. La taurina è stata somministrata alla dose di 150mg/kg/die e.v.. I risultati sono stati confrontati con quelli ottenuti in un gruppo di controllo di 10 pazienti con epilessia trattati con placebo. Il trattamento con taurina ha indotto un aumento dei punteggi dei test riferiti alle prestazioni intellettive in toto, in particolare la vivacità e prontezza intellettiva, l'interessamento all'ambiente, la motivaizione, le capacità attentive, mnemoniche e psicomotorie
