    Identity integration matters: The case of parents working from home during the COVID-19 health emergency

    Full text link
    Since February 2020, the world has faced a health emergency due to the rapid spread of COVID-19. Two of the first measures adopted by most countries to ensure social distancing were the closure of schools and childcare services, and the mandate to work from home. Millions of parents, while facing the threat of the virus infection, suddenly found themselves locked down in their homes managing workload and care load in single “crowded” spaces. This study tested whether relevant identity structures and individual differences (i.e., work-parent identity integration, identification with family, and identification with work) and contextual factors (i.e., work demands, family demands, and housing conditions) predicted parents’ professional, parental, and mental health outcomes during the lockdown. Data collected in April-2020 from 432 Italian parents working from home during the strict lockdown showed that the main predictor of all outcomes is work-parent identity integration. We provide recommendations for how professionals and organizations can support parents working from home due to COVID-19 or in future lockdowns

    Inversion of electrical conductivity data with Tikhonov regularization approach: some considerations

    Full text link
    Electromagnetic induction measurements, which are generally used to determine lateral variations of apparent electrical conductivity, can provide quantitative estimates of the subsurface conductivity at different depths. Quantitative inference about the Earth’s interior from experimental data is, however, an ill-posed problem. Using the generalised McNeill’s theory for the EM38 ground conductivity meter, we generated synthetic apparent conductivity curves (input data vector) simulating measurements at different heights above the soil surface. The electrical conductivity profile (the Earth model) was then estimated solving a least squares problem with Tikhonov regularization optimised with a projected conjugate gradient algorithm. Although the Tikhonov approach improves the conditioning of the resulting linear system, profile reconstruction can be surprisingly far from the desired true one. On the contrary, the projected conjugate gradient provided the best solution without any explicit regularization (a = 0) of the objective function of the least squares problem. Also, if the initial guess belongs to the image of the system matrix, Im(A), we found that it provides a unique solution in the same subspace Im(A)

    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

    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

    Full text link
    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

    How to Age More Positively? Analyzing Determinants that Shape Attitudes Towards Aging

    Full text link
    A considerable amount of research has illustrated that negative attitudes toward one’s own aging can directly hinder mental and physical well-being or lead to maladjustment in later stages of life (Swift et al. in Social Issues Policy Rev 11(1):195–231, https://doi.org/10.1111/sipr.12031, 2017). Research so far has focused on the analysis of individual factors related to attitudes toward aging, often related to personality traits. Our study proposes and tests a model of positive contact with aging (PCA). It analyses both individual and social antecedents of attitudes towards one’s own aging, hypothesizing that individual health self-efficacy directly affects attitudes towards one’s own aging and that the quality and quantity of contact with older adults indirectly impacts on attitudes towards one’s own aging through attitudes towards older adults. The model was tested in a wide sample of the Italian population (N = 753) with a varied age range. The PCA model tested showed excellent fit to the data, explaining a moderate amount of variance in attitudes toward one’s own aging (12%). This model promises to offer implications for active policies that can improve attitudes towards one’s own aging, promoting educational strategies to increase intergenerational exchanges and foster health-related self-efficacy
