    The impact of prepartum pandemic-related perceived stress on anxiety symptoms in the postpartum: The role of perceived childbirth experiences

    No full text
    Postpartum anxiety is a significant component of postpartum maternal distress and is related to adverse outcomes for both the mother and the child. Although previous research reported higher anxiety symptoms in pregnant women during the Covid-19 pandemic, no studies evaluated the negative impact of pandemic-related perceived stress on postpartum anxiety symptomatology over time. This study aimed to examine the impact of prepartum pandemic-related stress on postpartum anxiety and to evaluate the role of subjective labor and delivery experiences on this relationship. A sample of 172 pregnant women completed an online questionnaire evaluating pandemic-related perceived stress and anxiety symptoms in the second or third trimester of pregnancy. In the postpartum, they completed a second questionnaire retrospectively evaluating their childbirth experience and assessing anxiety symptoms in the last two weeks. A mediation analysis was conducted. Prepartum pandemic-related perceived stress was significantly associated with postpartum anxiety symptoms. Moreover, childbirth experiences significantly and partially mediated this relationship. Findings highlighted the importance of evaluating perceived stress levels during pregnancy to prevent negative consequences on postpartum mental health. Clinicians need to foster better management of factors included in the childbirth experience that may potentially trigger or counteract anxiety risk

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Vital exhaustion, sonno e qualità della vita nei caregiver di pazienti affetti da malattia di Alzheimer

    La letteratura internazionale ha evidenziato come i caregiver di pazienti con malattia di Alzheimer presentino un benessere psicologico e una salute fisica inferiore rispetto alla popolazione generale. Alcuni studi evidenziano che nei caregiver di pazienti con demenza il minore benessere psico-fisico è in relazione ad una minore qualità del sonno. Un’altra variabile spesso associata allo stress cronico e correlata allo sviluppo di patologie fisiche (es. cardiache) è la vital exhaustion, un costrutto costituito da un’eccessiva affaticabilità, irritabilità e demoralizzazione. Non ci sono però studi che valutano l’effetto di questa variabile nella salute fisica e mentale dei caregiver. Il presente studio longitudinale intende indagare l’associazione tra caregiver burden e qualità della vita (sia fisica che mentale) e il possibile ruolo mediatore della vital exhaustion e qualità del sonno. Sono stati coinvolti nello studio 108 caregiver (M=62,54, DS±14,47 anni) a cui è stato somministrato un questionario self-report in tre occasioni diverse: alla baseline (t1), tre mesi dopo (t2) e un anno dopo (t3). Gli strumenti utilizzati sono stati: lo Screen for Caregiver Burden, il Maastricht Vital Exhaustion Questionnaire, il Pittsburgh Sleep Quality Index e il Short Form-36 Questionnaire. Dalle analisi di regressione e mediazione è emerso che il caregiver burden a t1 ha un effetto indiretto significativo sul benessere fisico e mentale (t3) mediante la qualità del sonno e la vital exhaustion a t2; in particolare più il caregiver è stressato peggiore sarà la sua salute fisica (effetto completamente mediato dalla vital exhaustion e dalla qualità del sonno) e mentale (effetto parzialmente mediato dalla vital exhaustion e dalla qualità del sonno). In conclusione, un maggiore interesse deve essere dato al costrutto della vital exhaustion nell’analisi dell’esperienza di caregiving, in quanto costrutto a sé stante e con un effetto indipendente sulla salute del caregiver

    Variations on the Author

    “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

    We 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

    We 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 text
    We 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
