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
Forensic and psychopathological framing of complex suicides: A retrospective study over the last 30 years
No full textComplex Suicide (CS) is defined as an unusual form of suicide in which several harmful methods are used, simultaneously or in succession, whose purpose is to avoid the possible ineffectiveness of one of the methods used to produce a certain fatal outcome. The study of CS is of great interest and plays a fundamental role in characterizing the knowledge of these rare events. We have retrospectively evaluated all CS cases examined at the Institute of Forensic Medicine of Milan from 1993 to 2022 (n = 75) with the aim of characterizing the deceased who have resorted to it. We also compared the sample of 75 CS cases with a sample of paired 115 “simple” suicides (with a single method). Our analysis revealed that the CS cases were carried out by a “typical” subject identified as an adult male, between 41 and 50 years old, suffering from psychiatric disorders and, in particular, major depressive disorder. The most frequent harmful mode was plastic bag suffocation associated with self-poisoning. CS cases used less violent methods than simple suicide controls. The pathological-forensic approach has brought to light elements that can be useful both for forensic professionals (pathologists and psychiatrists) in correctly classifying these unusual and challenging events and for clinicians working on the front line. Some profiles have been outlined that can be used to identify potentially vulnerable individuals who could benefit from increased health surveillance to treat and prevent suicide
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
Is It Correct to Consider Caustic Ingestion as a Nonviolent Method of Suicide? A Retrospective Analysis and Psychological Considerations
Full text linkBackground: Suicide methods chosen by victims are particularly critical in suicide risk
research. To differentiate suicide deaths, it is usual to categorize them as violent and nonviolent
depending on the detrimental method chosen by the victims. Caustic ingestion, for example, is
traditionally considered as a nonviolent suicide method. It results in severe consequences for
the human body and it is associated with high levels of lethality. Methods: In this study, we
retrospectively analyzed suicides that occurred between 1993 and 2021 in Milan (Italy) and that
underwent autopsy. We compared a sample of 40 victims that ingested caustic substances with a
sample of 460 victims of other chemical ingestion, and a sample of 3962 victims from violent suicide.
Univariate analyses and univariate logistic regression models were performed. Suicides from caustic
poisoning were significantly older, had a higher mean number of diseases and were more affected
by psychiatric diseases compared to other chemical ingestion victims. By contrast, caustic suicides,
compared to violent suicides, had a more balanced gender ratio, a higher mean number of diseases,
were more affected by psychiatric diseases, had a higher rate of complex suicides (more than one
modality), and had victims who died more frequently inside instead of outside. In logistic regression
models, age was the only feature differentiating caustic from other chemical ingestion suicides while
the features differentiating caustic from violent suicides were gender, mean number of diseases and
suicide place. Conclusions: Suicides by caustic ingestion showed substantial differences compared to
violent suicides, with a higher severe profile. However, some differences were reported comparing
caustic ingestion to other chemical ingestion as well. Thus, we argue whether it is more appropriate
to differentiate the suicidal ingestion of caustics from both violent and nonviolent suicide methods
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
