Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
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

Exploring the impact of childhood trauma on obsessive-compulsive disorder: A systematic review focused on adult populations
No full textBackground: Childhood trauma has been linked to various psychiatric disorders, including obsessive-compulsive disorder (OCD). However, the relationship between specific types of childhood trauma and their impact on the subtypes and severity of obsessive-compulsive symptoms remains poorly understood. This systematic review aims to consolidate current evidence on the potential associations between childhood trauma and obsessive-compulsive symptoms. Methods: We conducted a systematic search across four electronic databases, including PubMed, Web of Science, EMBASE, and PsycINFO, to identify studies examining the relationship between childhood trauma and obsessive-compulsive symptoms. Eligible studies were screened, data extracted, and methodological quality assessed. Results: The final selection consisted of 22 studies corresponding to 5603 individuals with a diagnosis of OCD (mean age: 29.8 ± 9.9 years; 52% females). The findings suggest that individuals with OCD frequently have childhood trauma. Emotional abuse and neglect were significantly associated with higher Yale-Brown Obsessive-Compulsive Scale scores and increased prevalence of religious, sexual, and aggressive obsessions. Two studies identified potential mechanisms linking trauma to OCD, including cerebellar remodeling and dysregulation of stress-response systems. Conclusions: Childhood trauma, particularly emotional abuse and neglect, appears to contribute to OCD severity and symptom specificity, with trauma histories being more pronounced in treatment-resistant cases. These findings highlight the importance of trauma-informed care in OCD assessment and treatment. Future research should address methodological heterogeneity, explore longitudinal pathways, and investigate neurobiological mechanisms to elucidate the trauma-OCD relationship further
Traumatic Childbirth Experiences and their Association with Postpartum Psychiatric Disorders: A Systematic Review
No full textTraumatic childbirth experiences, characterized by intense fear, helplessness, or loss of control during labor or delivery, may increase the risk of postpartum psychiatric disorders. Events such as emergency cesarean sections, preterm births, and neonatal intensive care unit admissions have been associated with elevated psychological distress. This systematic review aimed to synthesize current evidence on the association between traumatic childbirth experiences and postpartum psychiatric disorders, including depression, post-traumatic stress disorder, and anxiety. A systematic search of PubMed, Web of Science, EMBASE, and PsycINFO databases was conducted. Two reviewers independently performed study selection, data extraction, and quality assessment using the Newcastle-Ottawa Scale. Eighteen studies involving 1,892 women were included. Rates of postpartum depression and post-traumatic stress disorder were consistently higher among women who experienced emergency cesarean sections compared to vaginal deliveries. Considerable heterogeneity was observed across study designs, populations, and assessment methods. This review suggests a consistent association between traumatic childbirth experiences and postpartum psychiatric disorders. Further longitudinal research using standardized methodologies is needed to clarify causal mechanisms and inform the development of effective trauma-informed interventions to support maternal mental health
