Sense of Community, Unfairness, and Psychosomatic Symptoms: A Multilevel Analysis of Italian Schools
No full textChanging to Impress: Testing a Mediation Model from Instagram Self-presentation to Cosmetic Surgery
Full text linkBackground This study examined the relationship between false self-presentation on Instagram and consideration of cosmetic surgery through the mediating role of body image control in photos (BICP), photo manipulation, and body shame. We predicted that false self-presentation on Instagram was indirectly associated with cosmetic surgery intentions through the aforementioned constructs. Methods A total of 504 young Italian adults (28.2% males, 18-30 years) completed an online survey. They completed a questionnaire containing the Self-presentation on Instagram Questionnaire, the Body Image Control in Photos Questionnaire-revised, the Photo Manipulation Scale, the Objectified Body Consciousness Scale, and the Acceptance of Cosmetic Surgery Scale. The pattern of associations between the constructs was analyzed via path analysis. Results The results show that false self-presentation on Instagram was associated with photo manipulation, both directly and indirectly, through BICP. Furthermore, photo manipulation was linked to body shame, but neither of them was associated with cosmetic surgery intentions. Finally, false self-presentation on Instagram was associated with the consideration of cosmetic surgery only through the mediation of BICP. Conclusion Findings indicate that self-presentation styles might affect Instagram photo behaviors and individuals' cosmetic surgery intentions, suggesting that surgeons should fully examine patients' motivations before providing them with services. Furthermore, intervention programs encouraging users to present a more authentic version of themselves online might reduce the risk of self-objectification and reduce the consideration of procedures aimed at modifying one's body for purely aesthetic reasons.

“Volunteering by Chance” to Promote Civic Responsibility and Civic Engagement: Does It Work?
No full textThis study investigated the effectiveness of a program to promote civic responsibility and prevent antisocial behavior in a sample of Italian adolescents. Participants were 83 Italian male adolescents, attending the second year of high school (Mean age = 15.79; SD = 0.87). In order to test the efficacy of different strategies (in-classroom training and service activity in a voluntary organization) we divided students into two experimental groups—one classroom of students participated in both strategies (training + volunteering group) and another classroom only participated in the training (training only group)—and one control group. Process and efficacy evaluations were completed. Data were collected before and following the intervention. The process evaluation revealed that the program was highly accepted and appreciated by students. The efficacy evaluation revealed no intervention effects on civic responsibility. However, the training + volunteering group reported a significant decrease in antisocial behavior after the program. Thus, the program was effective in preventing antisocial behavior but not in promoting civic responsibility in our sample
Adolescent gambling and impulsivity: does employment during high school moderate the association?
Full text linkThe aim of the present study was to examine the potential moderating relationships between adolescent gambling and impulsivity traits (negative urgency, positive urgency, lack of premeditation, lack of perseverance and sensation seeking) with employment status. High-school students (N=400; 69% male; mean age=18.35 years; SD=1.16; past year gamblers) were surveyed to provide data on impulsivity and employment. Multiple linear regression analysis was applied to examine associations with gambling and related problems. Positive urgency was associated with stronger scores of both gambling frequency and problem gambling. Students in employment had substantially higher frequency of gambling and greater problem gambling. Moreover, the combination of having a job and low perseverance was associated with a particularly high frequency on gambling. These findings further support the importance of positive urgency and employment status in adolescent gambling. The study highlights unique moderating relationship between gambling and lack of perseverance with employment status. Youth with a low perseverance and having a job may have particular need for interventions to reduce gambling
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
Social Capital and Fear of Crime in Adolescence: A Multilevel Study
No full textHierarchical linear modeling was used to examine the relationships between social capital (at the individual, the neighborhood, and the regional levels) and adolescents' fear of crime, while controlling for the main individual (sociodemographics, television viewing, and bullying victimization), neighborhood (neighborhood size and aggregated victimization), and regional (crime rate and level of urbanization) variables. Data were analyzed using a three-level model based on 22,639 15.7-year-old (SD = 0.67) students nested within 1081 neighborhoods and 19 Italian regions. The findings revealed that individual and contextual measures of social capital, modeled at the individual, neighborhood, and regional levels simultaneously, showed negative associations with adolescents' fear of crime. Males and participants with higher family affluence were less likely to feel fear of crime, whereas victimization, both at the individual and neighborhood levels, had a positive association with fear of crime. Strengths, limitations, and potential applications of the study are discussed.</p
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
