Color-blindness in Calabria (Southern Italy): A north-south decreasing trend
No full textThe frequency of color-blindness (CB) in 13,072 males from 409 towns in Calabria is 5.42%. Regional variation in CB within the three provinces of Calabria was studied: Cosenza (northern), Catanzaro (central), and Reggio Calabria (southern). There is a decreasing trend of mean frequencies of CB from Cosenza to Reggio Calabria through Catanzaro: 6.23%, 4.65%, and 3.43%, respectively. The mean frequencies do not take into account the two ethnic minorities present in Calabria: Albanians and Grecanicans. The frequency of CB mean Albanians (7.40%) and the indigenous Calabrian population (5.25%) differs significantly. Moreover, the Albanians do not show the protoanomalous phenotype. The small sample size of Grecanicans does not permit an evaluation of mean CB frequency. Thus, from the perspective of CB, the Calabria region may be considered a mixture of "genetic isolates" reflecting its historical, sociocultural, demographic, and genetic features. Am. J. Hum.

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
Affective temperaments and clinical course of bipolar disorder: An exploratory study of differences among patients with and without a history of violent suicide attempts
No full textBackground and Objectives: Suicide is the leading cause of death in patients with Bipolar Disorder (BD). In particular, the high mortality rate is due to violent suicide attempts. Several risk factors associated with suicide attempts in patients with BD have been identified. Affective temperaments are associated with suicidal risk, but their predictive role is still understudied. The aim of this study is to assess the relationship between a ff ective temperaments and personal history of violent suicide attempts. Materials and Methods: 74 patients with Bipolar Disorder type I (BD-I) or II (BD-II) were included. All patients filled in the short version of Munster Temperament Evaluation of the Memphis, Pisa, Paris and San Diego (short TEMPS-M) and the Temperament and Character Inventory, revised version (TCI-R). The sample was divided into two groups on the basis of a positive history for suicidal attempts and the suicidal group was further divided into two subgroups according to violent suicide attempts. Results: Violent suicide attempts were positively associated with the cyclothymic temperament and inversely to the hyperthymic one. BD-I patients and patients with a clinical history of rapid cycling were significantly more represented in the group of patients with a history of violent suicide attempts. Conclusions: Our study highlights that several clinical and temperamental characteristics are associated with violent suicide attempts, suggesting the importance of a ff ective temperaments in the clinical management of patients with BPI
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
The de Clérambault syndrome: more than just a delusional disorder?
No full textThe de Clérambault syndrome, commonly known as erotomania, is a delusional disorder in which the patient is convinced that another person has fallen in love with him or her. The syndrome is more frequent in female patients, who usually believe that their lover is a man belonging to a higher social and economic class, or is married, unknown, or even imaginary or deceased person. The course of the syndrome is usually chronic, with serious problematic behavioural consequences, including stalking behaviours, such as repetitive calling, unexpected visits or continuous attempts to send gifts or letters. According to the DSM-5, this syndrome is included in the erotomanic type of the delusional disorder, however, it is usually neglected in psychiatric practice and almost forgotten by modern psychiatrists
