The role of reciprocation in social network formation,with an application to LiveJournal

This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment model to study how reciprocation affects the build-up of the individual social capital of bloggers, as measured by their links and interactions with others. This allows us to measure the role of content production and relationship building in the dynamics of online social networks and to distinguish between the social networking and media aspects of blogging.     

Measurement Invariance of Ryff’s Psychological Well-being Scales Across Italian and Belarusian Students

Cross-cultural researches on the Ryff’s Psychological Well-being (PWB) Scales are currently not available. The aim of the paper was to investigate the measurement invariance of the 18-item version of the PWB Scales across 1,114 high school and undergraduate Italian and Belarusian students. After identifying the six correlated first-order factors and one second-order factor model of the Ryff’s PWB Scales, as baseline model for each sample, multi-groups confirmatory factor analyses were subsequently performed. All analyses were performed using the Robust Diagonally Weighted Least Squares estimation procedures, entering a polychoric correlation matrix. Multi-groups analyses showed that factor structure of the preferred model did not change across the Italian and Belarusian samples. Although the obtained results provided a preliminary support for cross-cultural structural invariance of the PWB Scales, further investigations are required to ensure its generalizability and applicability. Limitations and suggestions for future researches as well as psychosocial applications for educational context were discussed.     

Examining the Incidence and Clients’ Experiences of Single Session Therapy in Italy: A Feasibility Study

Single session therapy (SST) postulates that one session can be sufficient for a client to take charge of the process and work toward their own solutions. Research has been conducted worldwide corroborating SST assumptions with several mental health conditions, but not in Italy. For the first time in Italy, this paper aims to explore: (1) if the most frequent number of sessions in traditional psychotherapy (not SST) is one (Study 1); and (2) the satisfaction of clients who attend SST services and the number who consider one session sufficient to address their presenting problem (Study 2). In Study 1, the records of 476 voluntary clients referred to three different traditional (not SST) psychological services in the west-central region of Latium, Italy, were retrospectively screened, and the number of sessions attended by each client recorded. In Study 2, 85 consecutive clients who voluntarily asked for SST with seven mental health professionals across Italy received a link to an online ad hoc survey, 1–3 weeks after the consultation, evaluating their experience. Study 1 found that the most frequent number of traditional psychotherapeutic (not intentionally SST) sessions was one (124 out of 476 clients (26%). Study 2 found that 44 out of 85 clients (52%) considered one session to be enough, as they felt better or much better and chose not to attend further sessions. Of those who asked for a second session (41 clients), 33 clients (80.5%) indicated that the first session was not enough and 8 clients (19.5%) wanted to address a new problem. These results converge with previous international studies and provide encouragement for the use of SST in both private and public psychological services to address the demand for timely mental health services in Italy. Further research is needed to support the efficacy of SST and to evaluate its cost-effectiveness.     

Skill Complementarities and Migration Decisions

This paper offers an explanation of the high mobility of skilled workers based on human capital complementarities. If the skill premium is increasing in the average level of human capital of a location, and there exist fixed migration costs, in equilibrium the more skilled the workers are, the stronger the economic incentives to migrate towards the richest regions will be. Moreover, endogenously generated differences in productivity due to migration affect occupational choices and regional specialization. Empirical evidence consistent with the proposed explanation is provided using data on Italian regions. It emerges that, even after controlling for economic conditions, a high population share of individuals who completed college or high‐school in a region seems to be a relevant pull factor for the most educated migrants. In contrast, the importance of this variable, which measures the average level of human capital of a location, drops when unskilled migrants are considered. Finally, the effects of migration on the evolution of regional disparities are taken into account.
