An interpretation of the landsliding process affecting the town of Roccella Valdemone
No full textThe western slope of the small town of Roccella Valdemone, in Sicily, is affected by a landslide that in 1950 reached the urban centre, subsequently propagated uphill up until 1996, and destroyed many constructions. The mass movement involves essentially stiff tectonised clays and heterogeneous argillaceous debris. The causes and the evolution of the landsliding process are discussed in the paper, in which the devised, and par-tially implemented, remedial measures are also outlined
Interventi di adeguamento di alcune banchine del Porto di Messina
No full textIl Porto di Messina comprende banchine realizzate con muri di sponda e banchine a giorno. Sulle banchine sono stati eseguiti nel passato interventi di vario tipo. Recentemente è stato eseguito uno studio sistematico sui terreni di fondazione delle banchine, sulla consistenza delle opere di fondazione e sullo stato di degradazione delle strutture. Le condizioni di sicurezza della maggior parte delle opere sono risultate insoddisfacenti. È stata di conseguenza necessaria l’attuazione di interventi di consolidamento. Nella memoria si illustrano i risultati delle indagini e delle valutazioni concernenti la sicurezza delle opere, i criteri di scelta e di verifica degli interventi di consolidamento. Si riportano infine i risultati delle sperimentazioni in situ e delle osservazioni sul comportamento delle opere durante e dopo l’esecuzione dei lavori di stabilizzazione e adeguamento eseguiti
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
The cerebellar role in attention
No full textBackground: Clinical and functional neuroimaging studies showed a cerebellar involvement in different attention tasks. Nevertheless, most studies have focused on single aspects of attention and it is still lacking a consensus regarding the overall cerebellar contribution to this function.
Methods: A computerized battery (“Test-Battery of Attentional Performance”, TAP) was administered to cerebellar patients and healthy subjects well-matched for age and education, to analyze various components of attention.
A one-way ancova was used to evaluate eventual differences between patients’ and controls’ performances. Simple tapping reaction time was used as covariate to exclude the influence of the motor component on the cognitive performance.
Results: Cerebellar patients were significantly impaired in divided attention, flexibility and sustained attention tasks, while there were no differences between patients and control groups in go-nogo, working memory, spatial attention and ocular movements tasks. These results demonstrate that cerebellar damage produces deficits in attentional domain that may be the consequence of the existence of discrete parallel circuits that connect specific cerebellar portions with specific areas of the cerebral cortex.Background: Clinical and functional neuroimaging studies showed a cerebellar involvement in different attention tasks.

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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
