No full textMental Images and School Learning: A Longitudinal Study on Children
Full text linkRecent literature have underlined the connections between children’s reading skills and capacity to create and use mental representations or mental images; furthermore data highlighted the involvement of visuospatial abilities both during math learning and during subsequent developmental phases in performing math tasks. The present research adopted a longitudinal design to assess whether the processes of mental imagery in preschoolers (ages 4–5 years) are predictive of mathematics skills, writing and reading, in the early years of primary school (ages 6–7 years). The research lasted for two school years; in the first phase, the general group of participants consisted of 100 children, and although all participants agreed to be part of the research, in the second phase, there was a mortality rate of 30%. In order to measure school learning and mental imagery processes four batteries of tests were used. The mental imagery battery evaluated mental generation, inspection and transformation processes. Data underlined that the different aspects in which mental imagery processes are articulated are differently implied in some skills that constitute school learning. These findings emphasize the potential usefulness of a screening for mental imagery ability for schoolchildren to adopt effective measures to increase their mental imagery abilities
Development of the Mental Imagery Scale for Preschool Children using Classical Test Theory and Item Response Theory
No full textThis study aimed to develop a measure of mental imagery evaluation in preschool children. Three studies were conducted: Study 1 focused on the exploration of the factorial structure, reliability, and Item Response Theory (IRT) discrimination on a sample of children from 4 to 5 years old (N = 100; 50% males and 50% females); Study 2 focused on the confirmation of results about dimensionality on a sample of children from 4 to 7 years old (N = 170; 50% males and 50% females); and Study 3 focused on verifying criterion validity on a sample of children from 4 to 5 years old (N = 70; 47.1% males and 52.9% females). The results confirmed the hypothesis of three reliable factors underlying the scale for the three tasks: Blind Touch, Are Letters and Forms Similar?, and Snail’s Walk. Findings from item parameterization showed a reasonably good discrimination power and low difficulty. Overall, our research has shown that the Mental Imagery Scale for Preschool Children (MIS-PC) is a valuable tool for measuring preschoolers’ mental imagery and encourages its application in the educational context
Wanna Bet? Investigating the Factors Related to Adolescent and Young Adult Gambling
No full textFor many adolescents and young adults, gambling can represent an attractive and exciting form of entertainment, a way to take risks and explore new experiences. However, gambling also poses a significant risk for this age group. Research suggests that adolescents and young adults are particularly vulnerable to the negative consequences of gambling, including addiction, financial difficulties, and mental health issues. This paper aims to critically examine data on adolescent and young adult gambling, focusing on the risk factors associated with gambling behavior. A total of 326 subjects (Mage = 19.01; SD =2.72), of whom 65.5% were female, completed a protocol containing a demographic sheet, the Lie/Bet Questionnaire, the Seven Domains Addiction Scale (7DAS), a subscale of the Addictive Behavior Questionnaire and the Coping Inventory for Stressful Situations (CISS). Specifically, we explored the impact of sociodemographic, environmental, psychological, and cognitive factors on adolescent and young adult gambling behavior. Clinical implications and future directions are discussed
Psychological status of infertile patients who had in vitro fertilization treatment interrupted or postponed due to COVID-19 pandemic: a cross-sectional study
No full textPurpose: To explore the psychological status of infertile women and men who had in-vitro fertilization (IVF) treatment interrupted or postponed because of the COVID-19 emergency.
Materials and methods: An electronic survey (NCT04395755) was e-mailed between April and June 2020 to couples whose IVF treatments have been interrupted or postponed due to the COVID-19 pandemic. The presence and severity of symptoms suggestive of anxiety and/or depression were assessed using the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9). Subjects with preexisting psychiatric disorders were excluded.
Results: Overall, 524 out of 646 patients completed the survey. The prevalence of anxiety and/or depression feelings was significantly higher in women, mainly if aged more than 35 years and with a previous IVF attempt. The occurrence of these psychological symptoms was significantly associated with the time spent on COVID-19 related news per day and partner with evidence of psychological disorder and, in females, with a diagnosis of poor ovarian reserve, diagnosis of endometriosis or uterine fibroids.
Conclusions: The psychological impact of the COVID-19 pandemic on the infertile couples who should have undergone IVF treatment has been significant. IVF centers should systematically offer these couples adequate psychological counseling to improve mental health
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
Le lacrime delle matrone nella tarda repubblica tra emotività, clichés rappresentativi ed esigenze di comunicazione.
No full textIl contributo indaga la funzione del pianto nelle dinamiche comunicative delle matrone romane nella tarda repubblica. Tradizionalmente connesso all’emotività femminile e divenuto
elemento topico nella rappresentazione delle donne, il pianto assunse una funzione fondamentale nelle dinamiche comunicative femminili tra II e I secolo a.C., quando le matrone agirono in politica, costrette dalla guerra civile in atto ad assolvere una funzione per loro esclusa dal codice di comportamento tradizionale
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
