Indagine sull'abbassamento del fiume Po. Analisi morfometrica dello stato attuale e tendenza evolutiva dell'alveo.
No full textLo studio riporta i risultati di una ampia indagine sullo stato del F. Po ed in particolare analizza l'evoluzione morfologica recente sulla base di numerose sezioni trasversali e profili longitudinali rilevati nell'ultimo secolo. L'analisi dei dati acquisiti ha consentito di stimare l'evoluzione futura dell'alveo sulla base delle condizioni osservate e le tendenza passate

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
Bed footboard peroneal and tibial neuropathy. A further unusual type of Saturday night palsy.
No full textAbstract
An uncommon cause of bilateral tibial and peroneal compression neuropathy is reported. After taking alcohol and drugs, a young heroin-addicted man lay unconscious overnight in supine position, with both legs crossing the wooden board at the end of the bed, the posterior aspect of the flexed knees pressing against its edge. The following day, he had weakness of foot flexion and extension and a sensory loss consistent with a bilateral tibial and peroneal neuropathy. Symptoms resolved rapidly in the left side; in the right side, a conduction block was still demonstrable 3 weeks later.

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
Description (reporting the actual words used in written letters) of the neuropsychological and psychopathological modifications produced by dopaminergic treatment in a young patient with Parkinson's disease.
No full textAbstract
Although it is an undeniable fact that dopaminergic therapy has greatly improved the quality of life and prognosis of patients with Parkinson's disease, various and serious adverse events correlated to dopaminergic drugs are not uncommon. Among these, those of neuropsychological and psychopathological nature are of particular importance, being capable of causing an upheaval in the basic personality of the patient. To this regard, the authors report the actual words of a patient himself that are far more convincing that any considerations we may express. In our opinion, the overwhelming impact of dopaminergic treatment on the psychopathological and neuropsychological equilibrium of all parkinsonian patients should unfailingly be carefully evaluated and pondered, particularly in the early onset forms of the disease.
