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
Dental evidence of human remains of a Slavic soldier population deported in concentration camps during World War II
No full textAims: The aim of this paper was to analyse post-mortem dental records of a collection of 93 skeletal remains exhumed from the ossuary of Bari Municipal Cemetery, Apulia, Italy. These skeletal remains belonged to Slavic soldiers deported in 1941 during World War II in two Italian concentration camps and who died in 1946–1947. Methods: A total number of 1949 teeth were analysed according to the American Board of Forensic Odontology and the WHO methods. The majority of the victims were men (95%) between the age of 18 and 62. Results: The results showed the dental health situation of a population of soldiers of World War II, in particular the high rate of caries (35%), periodontal disease (61%), and dental wear (65%) according to the high stress level of the soldiers during the armed conflict and the subsequent deportation. Conclusions: This is the first study reported in literature that analyses the effects of war and deportation on soldiers’ pathological conditions of the oral cavity. This analysis also confirmed the usefulness of teeth for anthropological and forensic research thanks to their high resistance and preservation even after post-mortem modifications and different environmental factors
Telepsychology revolution in the mental health care delivery: a global overview of emerging clinical and legal issues
No full textSince the outbreak of the COVID-19 pandemic, remote healthcare delivery by technological devices has become a growing practice. It represented an unprecedented change in personal and professional activities, allowing health specialists to continue working online by assisting their patients from home. Psychological practice greatly benefited from this innovation, guaranteeing diagnostic and therapeutic effectiveness through cyber counseling. However, in many countries there have been no enactments of specific laws nor adaptations of the professional deontological code aimed at regulating this new psychological practice dimension, generally defined as telepsychology. This article aims to briefly review the scientific literature on this tool’s effectiveness and especially analyze the legal and operational framework in which telepsychology has been to date practiced in Italy and other national realities, thus providing a global overview that may be useful to understand how to improve this valuable but still immature practice
THE PALEORADIOLOGY IMPORTANCE IN THE STUDY OF RELICS: THE UNIQUE DENSITOMETRIC ANALYSIS OF A BONE RELIC OF SAINT NICHOLAS
No full textDXA have greatly contributed to the development of paleoradiology, a branch of diagnostic imaging that allows to obtain information about human remains in contexts of archaeological and/or forensic interest. In this manuscript we report the unique experience of DXA performed on the relic of a Saint; in particular we analyzed a skeletal fragment of St. Nicholas, kept in the Basilica of Bari (Italy) since 1087. MATERIALS AND METHODS: The bone to be examined consisted of the posterior arch of the ninth left rib that was 12cm long, 1.2cm maximum width and 1.7cm thick at the body. The data acquired from the densitometric study were performed using the anthropometric measures reported in historical records of St. Nicholas' life: sex (male), age (75 years), weight (70kg), height (167cm), and ethnicity (Caucasian). In addition to the examination of the relic, a comparison assessment was made with the rib of a healthy 60 years old man (height of 170cm, without known skeletal pathologies). This sample had a length of 19cm, maximum width at the head 1cm, and 0.7cm thick at the body. The analysis of bone fragments is different from the analysis of bones in the context of the human body (where soft tissues are placed around the skeleton); for this reason, one of the most critical issues was to create a support that would allow the analysis of bone fragments. We simulated conditions similar to those occurring in patients: a density scale was established, using a specific plexiglass phantom on which the bone fragments to be examined were placed. From the analysis it was calculated the parameter bone mineral density (BMD), express in g/cm2, that indicates the relation between mass of bone mineral content and area of examined bone segment. BMD data was compared to a range normalized by age, sex and ethnicity (BMD-N). RESULTS: The results of the scannnig of St. Nicholas' rib showed a BMD of 0.97g/cm2 with a BMD-N between 0.77 and 1.08g/cm2. Simultaneous measurements of the relic compared with a reference rib showed highlighted BMD of 0.84g/cm2 for the relic and 0.50g/cm2 for the reference rib. The St. Nicholas data are 168% higher than reference bone. All our measurements of the relic indicated a high bone mineral density, most likely due to the presence of a high concentration of calcium salts. A relatively higher mineral density of the relic was seen compared to the healthy subject's rib. From the history of St Nicholas' life, we know of the long imprisonment at the age of 51 in damp and unhealthy environment. The results of this study suggest that a good bone mineral density was maintained by the Saint even in old age. An additional element that can influence bone mineral density is diet, certainly different during the time of St. Nicholas. The good bone densitometry indicates that the Saint maintained a proper diet, with a generally fair state of health. CONCLUSION: For this first DXA analysis of the rib relic of Saint Nicholas was necessary a long and complex experimental work to modify standard technique procedure to particular and unusual sample and Create specific supports and complementary instruments. Perform DXA analysis on relics permit to obtain additional information to living conditions, economical situation, behaviours, diet, diseaes, conservations conditions of remains, change of life style in different age. Our experimental work, the first of its kind, creates the way to analyze precious relics that often include only few bone fragments and data obtained by our work can be useful for a better management and movement of fragile relics. We ourselves are working on a new challenge for the analysis of bone finds from shipwrecks found at the bottom of the sea
