Willingness to Donate Organs After Death: Development and Validation of a Multidimensional Scale on Organ Donation
No full textBackground: Despite the growing number of organ transplants, there is still a significant difference between the number of donated
organs and the number of people waiting for them. Knowing the reason people decide to donate is the first step to increasing organ donation
rates. Aims: The main aim of the present study was to develop and validate a new scale for organ donation. Method: In three studies, 3,585
participants ranging in age between 14 and 89 years were selected through systematic random sampling. In the first study, we created a scale
following the organ donation model theoretical framework and submitted the scale to exploratory factor analysis. In the second study, we
performed a confirmatory factor analysis to cross-validate the hypothesized factor structure. In the third study, the scale was related to some
important variables involved in organ donation. Results: Exploratory factor analysis and confirmatory factor analysis with a good fit index and
acceptable levels of validity and reliability guarantee the quality of the scale and stable factor solution. Limitations: The main limitations are
connected to social desirability, the presence of systematic bias of the population that refused to take part in the study, and the use of the
Caucasian population. Conclusion: The resulting scale consists of 21 items in a seven-factor model (bodily integrity, fear of death, familial
beliefs, altruism, medical mistrust, trust in the health institution, and emotional support). We also observed the relationship between scale
factors, religiosity, and knowledge of organ donation with the willingness to donate organs
Vulnerable Narcissism and Sense of Community Among Adolescents: The Role of Self-Esteem and Use of Social Media
Full text linkThis study investigated the relationships among vulnerable narcissism, the use of social network sites (SNSs), self-esteem, and sense of community among adolescents. Based on a sample of 381 high school students, we explored whether vulnerable narcissism,
exacerbated by the use of SNSs and low self-esteem, contributes to difficulties in establishing community relationships. Hypotheses were tested to examine the associations among narcissism, sense of community, and self-esteem, with the use of SNSs as a moderating factor. The results indicated a negative relationship between narcissism and sense of community, with self-esteem mediating this relationship. Furthermore, the low or high use of SNSs moderates the negative relationship between narcissism and sense of community and self-esteem such that with high use of social media, the relationship becomes positive. These findings suggest that vulnerable-narcissist adolescents use social sites as facilitators of community relationships and support of their self-esteem.
Conversely, adolescents with low usage are less inclined to support real-life comparisons, perceiving the community as a dangerous testing ground to avoid. This study highlights the importance of addressing vulnerable narcissism and the use of SNSs in interventions aimed at promoting community involvement and well-being among adolescents
The role of sexting in couple wellbeing for Italian women during the second wave of the COVID-19 pandemic
Full text linkThe social isolation due to the COVID-19 pandemic had an impact on the
sexuality and quality of life of people around the world. A particularly negative
effect was detected on women’s sexual health. As a consequence, many women
began to use social media not only to stay in touch with their social networks,
but as a way of maintaining sexual contact. The main aim of this research is
to observe the positive effects of sexting in women’s wellbeing as a strategy to
manage the negative effects of a condition of forced isolation. We collected
all our data between November 2020 and March 2021 during a period of strict
restrictions in Italy due to the second wave of the COVID-19 pandemic. In Study 1,
the relationship between loneliness, sexting behaviors, and sexual satisfaction was
tested on 312 adult women. The results showed the mediator role of motivation
for sexting in the relationship between loneliness and sexual satisfaction. In Study
2, 342 adult women were organized into two groups (women who had sexting
at least once during the second wave of the pandemic = 203, and women
who did not have sexting during the pandemic = 139) and were assessed on
a couple’s wellbeing (intimacy, passion, commitment, and couple satisfaction)
and electronic surveillance. The results show that women who had sexting
during isolation had higher scores on intimacy, passion, couple satisfaction, and
electronic surveillance. These findings suggest the important role of sexting as an
adaptive coping strategy during particular conditions of social isolation
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
