Il prototipo di orientamento risultato dalla validazione sul campo del modello sperimentale
No full textNel capitolo si presenta il prototipo di orientamento risultato della rielaborazione del modello messo a punto nella prima fase della ricerca e rivisto alla luce degli esiti della seconda fase della ricerca-azione, che è stata dedicata alla validazione sul campo del modello. In particolare la sperimentazione ha riguardato la validità sia dell'impostazione concettuale e metodologica del modello, sia l'operatività dell'insieme delle schede predisposte come strumenti per gli orientatori, sia l'appropriatezza del mix delle figure professionali da includere le processo di orientamento per l'inserimento professionale dei disabili psichici e degli immigranti con disabilità
Comparison of the Accuracy of Markerless Motion Analysis and Optoelectronic System for Measuring Lower Limb Gait Kinematics
No full textBackground: Marker-based Optical motion tracking is the gold standard in gait analysis, for their detailed biomechanical modelling and accuracy. Today, in light of developing remote telemonitoring applications, markerless solutions are growing rapidly. Algorithms like Openpose can track human movement from a video. However, only few papers assess the validity of gait analysis using Openpose.Objective: The purpose of this study was to assess the Openpose reliability to measure kinematics and spatiotemporal gait parameters and to evaluate the minimum technical requirements.Methods: This analysis used video and optoelectronic motion capture simultaneously recorded. We assessed 4 healthy adults. To compare the accuracy of Openpose respect to optoelectronic system we computed the following indexes: the absolute error (AE) for spatiotemporal parameters and lower limbs kin, the lower limbs Range (ROM) of Motion's intraclass correlation coefficients (ICC), the cross-correlation coefficients (CCC) of normalized gait cycle joint angles computed with two systems.Results: The spatiotemporal parameter showed an ICC between good to excellent and the absolute error was very small: cadence AE < 0.56 step/min, Mean Velocity AE < 0.11 m/s, Stride length AE < 0.14 cm. The ROM of the lower limbs during gait showed a good to excellent agreement in the sagittal plane. Also the normalized gait cycle CCC value shown a strong coupling in the sagittal plane.Conclusion: We found Openpose to be accurate and reliably for sagittal plane gait kinematics and for spatiotemporal gait parameters in healthy adults
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
