The Compulsive Obsessive Disorder: many clues, still little evidence
Get PDFThe Obsessive-Compulsive Disorder (OCD) is a debilitating psychiatric condition characterized by intrusive, distressing obsessions and repetitive, ritualistic compulsions. Despite its relatively high prevalence, elucidating its pathogenesis remains a significant challenge. The present study aims to review the current understanding of OCD's pathophysiological mechanisms focusing on the role of cortical and subcortical structures and their connections, proposing that obsessions may be a consequence, rather than a trigger, of compulsions. For this reason, the syndrome might be rebadged as the Compulsive Obsessive Disorder (COD). This will be explored, from a neurocognitive point of view, as an imbalance between goal-directed and habitual behaviour. Moreover, the issue of refractoriness will be addressed - with emphasis on the complex mechanisms that underlie refractory OCD and the cruciality of developing targeted interventions. This review discusses the potential contributors to treatment resistance, including neurobiological alterations, comorbid psychiatric conditions and the duration of untreated illness, a potential modifiable parameter which influences clinical outcomes. Innovative interventions offer hope for individuals with refractory OCD. The evolving landscape of OCD treatment will be overviewed, ranging from pharmacology to neurostimulation and novel psychotherapeutic techniques tailored to refractory cases which have shown promise in ameliorating symptoms when traditional approaches fall short
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
Suicide risk and suicide risk factors among immigrants in Italy: A bi-center matched sample study
No full textItaly has the third-largest immigrant population of European Union countries, but only a few research papers have examined suicide risk in immigrant psychiatric patients in Italy. The main aim of this paper was to compare suicidal ideation and suicide attempts in a sample of 304 psychiatric patients. We included 152 immigrant patients matched with 152 Italian patients admitted to the same wards during the same time period by age, gender, and diagnosis. We also investigated sociodemographic and clinical characteristics of the two samples including psychiatric diagnosis, age of illness onset, duration of illness, previous hospitalizations, length of hospitalization, previous suicide attempts, and substance and alcohol abuse. There were no differences between immigrant and Italian patients in either suicidal ideation (previous or current) or suicide attempts (previous or current). Immigrant patients were more likely to have a shorter duration of illness than the Italian patients and Italian patients were more likely to report substance abuse than were immigrant patients. Despite similar suicide rates between immigrants and Italian psychiatric inpatients, appropriate assessment of suicide risk in these patients is essential in implementing therapeutic suicide prevention strategies
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
Impact of longitudinal social support and loneliness trajectories on mental health during the COVID-19 pandemic in France
Get PDF(1) Background: Little is known about how the COVID-19 pandemic has impacted social support and loneliness over time and how this may predict subsequent mental health problems. This study aims to determine longitudinal trajectories of social support and loneliness in the French general population during the first year of the COVID-19 pandemic and study whether variations in these trajectories are associated with symptoms of depression and anxiety; (2) Methods: Analyses were based on data from 681 French participants in the international COVID-19 Mental Health Study (COMET) study, collected at four periods of time between May 2020 and April 2021. Group-based trajectory modelling (GBTM) was used to determine social support and loneliness trajectories. Associations between the identified trajectories and symptoms of depression and anxiety, measured with the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7), were tested through multivariate linear regression models; (3) Results: Social support trajectories revealed four stable groups: ‘poor’ (17.0%), ‘moderate’ (42.4%), ‘strong’ (35.4%) and ‘very strong’ (5.1%). Loneliness trajectories also identified four groups: ‘low stable’ (17.8%), ‘low rising’ (40.2%), ‘moderate stable’ (37.6%) and ‘high rising’ (5.0%). Elevated symptoms of depression were associated with poor social support as well as all identified loneliness trajectories, while high levels of anxiety were associated with moderate stable and high rising loneliness trajectories; (4) Conclusions: High and increasing levels of loneliness are associated with increased symptoms of depression and anxiety during the pandemic. Interventions to address loneliness are essential to prevent common mental health problems during the pandemic and afterwards
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
