Unravelling the relationship between anxiety, autonomic nervous system dysfunction and fibromyalgia: a systematic review
No full textFibromyalgia (FM) is a chronic condition characterised by widespread musculoskeletal pain accompanied by various somatic and psychological debilitating symptoms. Dysfunction of the autonomic nervous system (ANS), as measured by heart rate variability (HRV), including reduced HRV at rest and dysfunctional HRV response patterns, has been consistently reported in patients with FM. Additionally, FM patients commonly exhibit elevated anxiety symptoms and comorbid anxiety disorders. This systematic review aimed to explore the potential relationship between elevated anxiety symptoms and reduced HRV in patients with FM. Through a comprehensive analysis of the literature, the association between anxiety symptoms and HRV was investigated in FM patients under resting conditions and in response to various interventions. The results suggest that the association between reduced HRV and elevated anxiety symptoms in FM patients at rest is widely supported by most studies. Interventions focused on improving HRV, such as exercise, psychotherapy, and mind-body therapies, also appear to be effective in reducing symptoms of anxiety. These findings suggest the presence of a possible common underlying mechanism contributing to the high comorbidity of ANS dysregulation and elevated anxiety symptoms in FM. The observed interconnection between anxiety and HRV highlights the need to develop targeted, multimodal interventions aimed at simultaneously reducing anxiety and improving HRV to enhance the overall quality of life for individuals affected by this complex condition. Collectively, this systematic review underscores the importance of recognising and addressing the intricate interplay between psychological and physiological factors in the management of FM
Imparare ad imparare: Decostruire una storia per costruire la nostra storia
No full textDescriviamo una esperienza di avvio al pensiero computazionale attraverso attività di programmazione in ambiente Scratch realizzata in una classe seconda di scuola secondaria di I grado con insegnanti che stavano frequentando un corso di aggiornamento delle loro competenze digitali. Obiettivo di questa specifica esperienza è stato abituare alunni ed insegnanti ad imparare, da quello che già funziona, come risolvere i problemi che sorgono nella realizzazione di un nuovo progetto. Il modus operandi è decostruire una attività, nel caso in questione un programma realizzato in Scratch, andando ad individuare la soluzione ad un problema di interesse, astrarre questa soluzione e poi specializzarla a quanto interessa a noi realizzare. Così facendo ci uniamo a Dewey nel “...far conquistare agli allievi la pratica di scoprire come risolvere un problema da soli” [5] esercitando una forma dell’imparare ad imparare.
Si evidenzia come l’uso dell’ambiente Scratch faciliti l’individuazione, in particolare la verifica, della componente che in una attività funzionante può essere utile per una attività in costruzione.We describe an experience introducing computational thinking through programming using the Scratch environment. The activity has been carried out in a second grade middle school class with teachers who were undergoing a course for upgrading their digital skills. The objective of this specific experience was to get both students and teachers to learn how to solve the problems that arise in the implementation of a new project from programming activities already working. The modus operandi is to deconstruct an activity, in our case a Scratch program, in order to find in it the solution to a problem, then abstracting this solution and finally specializing again the abstraction into what interests us to have in the new project. By doing so, we join Dewey in "... making students learn the practice of finding out how to solve a problem on their own" [5] by exercising a form of learning to learn. We point out how using the Scratch environment facilitates the identification of the component that, in an already running activity, can be useful for another activity under implementation. In particular the Scratch environment simplifies verifying that the component works in the new context
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
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
