Epidemiology of foot deformities in Southern Italy: focus on Pes Planus and Pes Cavus
Background
Pes cavus and Pes Planus are two foot deformities and could be detected through baropodometrical digital techniques. In our study, we used computerized baropodometric analysis to make diagnosis of Pes planus and Pes cavus in the population of Foggia (Apulia Region, Southern Italy). The aim of our study was to calculate the prevalence of these deformities and to show significant differences due to gender or age.
Methods
We conducted a cross sectional study from January 2011 to August 2016, in the Orthopaedic Ambulatory of the LHU of Foggia, Italy. The patients were asked to sign a consent form to participate in the study. The baropodometric analysis was performed to diagnose Pes planus and Pes cavus, and additional information (gender and age) were recorded. We calculated percentages, means and standard deviation. The Chi-square test, and the calculation of Odds Ratio were used to identify differences due to these variables (sex and age).
Results
We performed 7816 baropodometric tests, and 978 patients were screened for suspected foot deformities: 668 cases of Pes cavus and 310 of Pes Planus were diagnosed. There is a statistically significant difference in the prevalence of Pes cavus and Pes Planus (p < 0.01) due to age: the young age is a risk factor for Pes Planus (OR = 1.61 CI 95% 1.22 - 2.11) but protective for Pes cavus (OR = 0.62 CI 95% 0.47- 0.81).
There is a statistically significant difference (p < 0.01) due to sex in the prevalence of hollow feet (OR = 0.44 CI 95% 0.33 - 0.59) and flat feet (OR = 2.23 CI 95% 1.68 - 2.98): beinga man reduces the risk for hollow feet, but increases the risk for flat feet.
Conclusions
Pes Planus and Pes cavus are not so spread in the general population but they represent an underestimated public health problem because these deformities negatively influence the productivity of workers. It would be interesting to continue our study evaluating also the impact of these problems on the quality of life of affected patients.
Key messages:
Pes cavus and Pes Planus are two foot deformities and the baropodometrical digital techniques are fundamental for their detection.
Pes Planus and Pes cavus are not so spread in general population but they represent an underestimated public health problem
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
Disabled students and the quality of relationships within the class
An investigation of the quality of peer relationships of disabled students within regular classes was conducted. A total of 496
students participated in the study, 40 of which disabled, enrolled in 27 public elementary and middle schools. The students filled
in the “Loneliness and Social Dissatisfaction Scale” (Asher, 1984) and responded to three questions of a sociometric test.
Disabled students significantly felt lonelier in class compared to the students with no disability. They were also often rejected or
left out during play activities, and probably due to the rejection experienced in class, over the years disabled students increasingly
expect rejection from their peers
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
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
