Young adults’ attitudes toward online self-disclosure and social connection as predictors of a preference for online social interactions: the mediating effect of relational closeness
No full textNowadays, computer-mediated-communication (CMC) has become integral to the interpersonal relationships, but the preference for CMC might produce negative outcomes. Specifically, attitudes toward online communication have been found concurrently associated with online relational closeness (RC) and problematic preference for online social interactions (POSI). Thus, mixed evidence regarding the effect of online communication attitudes has been found. The present paper aimed at validating online communication attitudes measures and exploring their direct and indirect effect on POSI, via RC. Two studies have been conducted. Study 1 evaluated the psychometric properties of online self-disclosure (OSD) and online social connection (OSC) subscales on a young adult sample (N = 820). Study 2 (N = 588) explored the direct and indirect predictive role of OSD and OSC on POSI via RC. The OSD and OSC subscales showed good internal consistency and reliability providing reliable instruments. Concerning the mediation analyses, the findings showed that both OSD and OSC predicted POSI. RC only partially mediated the relationship between online communication attitudes and POSI. Therefore, the online communication promotes online intimacy but, concurrently, it might represent a risk factor for psychological outcomes, such as POSI. The study provided novel findings concerning CMC and contributes toward the ongoing debate on possible predictors of POSI
Catalytic hydrodechlorination of decachlorobiphenyl
No full textThe hydrodechlorination (HDCl) process of decachlorobiphenyl (the most chlorinated among polychlorinated biphenyls (PCBs)) promoted by a presulphided NiMo/γ-Al2O3 catalyst has been studied. The experimental runs were carried out in a stirred batch reactor at constant temperature and pressure using hexadecane as reaction medium. Temperature levels T=250 and 300 °C at hydrogen pressure PH2=20 bar were tested. The kinetic analysis of both the overall hydrodechlorination process (organic chlorine→inorganic chlorine) and of the partial network (decachlorobiphenyl→nonachlorobiphenyls→products) was performed and the corresponding kinetic constants have been evaluated. The HDCl process was completed in about 240 min at T=250 °C and in <60 min at T=300 °C
Portfolio choice: Evidence from new-borns
Full text linkThis paper analyzes the role of newborn gender in households’ investment decisions. The results indicate that newborn gender is a significant predictor of both the reallocation of financial wealth across different types of financial assets and households’ investment diversification. Parenting a new baby boy is associated with a higher reallocation of wealth towards cash while the share of financial wealth allocated to risky assets decreases. A new baby boy also significantly reduces the magnitude of portfolio diversification. We find no evidence that the relationship between newborn gender and investment allocation is driven by third variables that simultaneously affect gender and financial decisions. The relationship between newborn gender and the financial decisions is particularly relevant to disentangle unconscious gender bias in households' investment decisions
Women’s pathological narcissism and its relationship with social appearance anxiety: the mediating role of body shame
No full textObjective: attention to personal appearance and observers’ judgments are integral components of narcissism. however, empirical evidence focused on the association between grandiose/vulnerable traits of narcissism and social appearance anxieties is limited. Moreover, body shame represents a topic of debated interest in the field of narcissism and women’s experience of self-consciousness. the aim of the present study is to evaluate the unexplored relationship between covert and overt facets of pathological narcissism and social appearance anxiety, analyzing the mediating role of objectified body shame.
Method: pathological vulnerable and grandiose narcissism, social appearance anxiety and body shame were assessed in a convenience sample of 775 young women (m=24.1, sd=4.52).
Results: body shame fully mediated the association between pathological narcissism and social appearance anxiety, especially for vulnerable narcissists’ women.
Conclusions: as expected, vulnerable narcissism had a positive association with social appearance anxieties, and body shame acted as a mediating risky factor. Moreover, as hypothesized and differently from recent findings, also overt narcissism was related to body shame and appearance anxieties. These findings suggest that feelings of shame are essential to deeper understand the narcissistic core features and outcomes. research and clinical implications are discussed
WHICH ARE THE EFFECTS OF BODY-OBJECTIFICATION AND INSTAGRAM-RELATED PRACTICES ON MALE BODY ESTEEM? A CROSS-SECTIONAL STUDY
Full text linkObjective: According to the objectification framework, media pressure toward
body models promotes the internalization of beauty ideals that negatively influence
individuals’ body image and self-esteem. Historically, women have been the main
target of sociocultural pressures. However, research has recently suggested that
self-objectification is a male phenomenon as well, which can be inscribed in men’s
body experiences. Nevertheless, fewer studies have specifically focused on the male
experience and general consequences of body-objectification are yet to be extensively
analyzed regarding males’ body image features. The current cross-sectional study
explores the consequences of body-objectification on male body esteem, specifically
testing the predictive role of exercising/dietary habits, body-objectification features,
and SNS-related practices on male body esteem.
Method: A total of 238 male participants (mean age = 24.28 years, SD = 4.32)
have been involved in an online survey. Three hierarchical analyses were performed
to test the influence of objectified body consciousness and social networking-related
experiences (i.e. Instagram intensity use, photo manipulation, selfie feedback
investment) on young men’s body esteem with specific reference to the weight,
appearance, and attribution features of the Body Esteem Scale.
Results: Findings highlighted that body shame played an interesting key role,
influencing negatively all the body esteem dimensions, thus highlighting that
attention needs to be deserved on this feature of OBC regarding males’ experience.
On the contrary, appearance control-related dimensions positively influenced body
esteem. Overall, findings confirmed that objectification theory can adequately mark
a pathway by which media imagery is internalized also by men and may negatively
affect their body esteem.
Conclusions: Despite some limitations, this study may contribute to enlarging
our knowledge on male body image and self-objectification experience and support
literature shattering the stereotype that body dissatisfaction is a “female-exclusive”
issue. Likewise, beyond some questioning positions, these findings also encourage
further exploration of a healthier “control dimension”, including body appearance related activities and beliefs
