Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Prevalence and determinants of hip pain in non-ambulatory cerebral palsy children: a retrospective cohort study
BACKGROUND: Hip pain is common in cerebral palsy children, particularly at Gross-Motor Function Classification System level IV-V. It is associated to hip displacement and relates to the migration percentage. Recent literature suggested early reconstructive bone surgery, as the best approach to prevent hip luxation, then hip pain. Still, high rates of hip pain are reported.AIM: To investigate prevalence and determinants of hip pain in an Italian cerebral palsy sample.DESIGN: Single-center retrospective cohort study.SETTING: Inpatient and outpatient. POPULATION: Patients with spastic or dyskinetic cerebral palsy, Gross-Motor Function Classification System level IV or V, age 0-18.METHODS: A chart review was implemented to report hip pain, as a dichotomous variable (pain/no pain), age, sex, cerebral palsy subtype, Gross-Motor Function level, lumbar scoliosis, migration percentage, previous orthopedic surgery, or botulinum injections, oral or intrathecal baclofen, drug-resistant epilepsy, assistive devices for standing or walking. Descriptive statistics and a multivariate logistic stepwise regression were performed.RESULTS: A total of 504 subjects were included: 302 level V, 209 females, 432 spastics. The mean length of follow-up was 6 years. The overall prevalence of hip pain was 8.9% (6.3% were at level V) and of hip dislocation was 19% (15.9% were at level V). Just 39% of dislocated hips were painful. Children at spastic subtype and level V were predominantly affected. Botulinum and soft tissue surgery related to lower rates of hip pain, without statistical significance. Age (OR 1.19, 95%CI 1.14-1.25, P value 0.000), sex (OR 1.72, 95%CI 1.18-2.52, P value 0.005), migration percentage (OR 1.02, 95%CI 1.02-1.03, P value 0.000) and lumbar scoliosis (OR 1.32, 95%CI 0.86-2.01, P value 0.200) resulted significant independent determinants of hip pain. CONCLUSIONS: Hip pain relates with the migration percentage, but not all dislocated hips become painful. Hip pain may be transient and requires a targeted and individualized approach. Children at spastic subtype and level V were predominantly affected. Age and sex are confirmed as determinants. Specific validated measures are to be implemented to assess hip pain.CLINICAL REHABILITATION IMPACT: Considering severe non-ambulatory cerebral palsy patients, pain and quality of life should be con-sidered as outcomes, in the management of hip luxation.(Cite this article as: Faccioli S, Sassi S, Ferrari A, Corradini E, Toni F, Kaleci S, et al.

Appropriate Similarity Measures for Author Cocitation Analysis
We 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
La compensatio lucri cum damno in ambito medico: analisi di tre fattispecie emblematiche alla luce della più recente giurisprudenza
Il contributo sviluppa una riflessione sulla compensatio lucri cum damno muovendo da tre fattispecie, riferibili al complesso panorama della responsabilità medica, in cui è stata richiamata, per lo meno in via ipotetica, la citata figura: i) il concorso tra risarcimento del danno patrimoniale ed identità c.d. di accompagnamento in ipotesi di invalidità derivante da colpa medica; ii) il concorso tra risarcimento del danno alla salute ed indennità ex l. n. 210/1992 (con particolare riguardo alle emotrasfusioni e alla somministrazione di emoderivati infetti); iii) concorso di danno e vantaggi nel caso di nascita c.d. indesiderata
Equinus foot classification in cerebral palsy: an agreement study between clinical and gait analysis assessment.
BACKGROUND: Excessive ankle plantar flexion (equinus foot) is a common problem in cerebral palsy (CP) and several treatment options can be considered depending on the equinus type. Few attempts have been made to classify different forms of equinus foot for specific treatment.AIM: This study is aimed at defining equinus foot types in CP patients according to the Ferrari classification, integrating clinical and instrumental assessments. The hypothesis is that clinical differentiation of equinus foot can be evidenced by recurrent anomalies identifiable through gait analysis (GA), which can make the assessment, usually based only on clinician semeiotics, more objective.DESIGN: Clinical and instrumental assessments were performed separately by a senior CP physiatrist and a senior GA physiatrist, the latter was blind to the clinical diagnosis of equinus type.SETTING: OutpatientsPOPULATION: Twenty patients, 16 diplegics and 4 hemiplegics (mean age 11 years, SD 4 years 11 months).METHODS: Clinical assessment by means of Modified Ashworth Scale, Gross Motor Function Measure (GMFM), Observational Gait Analysis (OGA), and measurement of lower limb muscle strength by dynamometer were used to classify the equinus type. Gait analysis assessed the kinematics and EMG of affected lower limbs.RESULTS: Ten different equinus types were identified. Since various forms of equinus can be present in the same patient, we were able to classify a total of 61 types of equinus in 36 feet. Substantial agreement was found between Clinical and Gait Analysis equinus assignment matched in 50 out of 61 types (Index of agreement with Fleiss' Kappa 79.3 % ). In some case only Gait Analysis was able to identify the equinus type, while in others it did not confirm clinical assignment.CONCLUSION: Gait analysis is able to distinguish different equinus types according to Ferrari classification, making the clinical decision less arbitrary. CLINICAL REHABILITATION IMPACT: Correct objective diagnosis of equinus foot in CP patients is of paramount importance when choosing suitable rehabilitative interventions

Dispelling the Myths Behind First-author Citation Counts
We 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
