Risk habits among Italian university students: sensation seeking and sexual risk-taking behaviors

Using data coming from the survey on “Sexual and Emotional Life of Youths”, we aim at exploring the patterns of relationships among risk habits, in particular the sex related ones among Italian university students to identify different risk profiles by using a sequential two-step analysis. Results highlight the presence of eight different target groups of students in terms of risk habits. Among them, the 24.9% of students can be defined as “young sensation seekers” who have the highest risk habits. Conversely, the 22.8% of students have inactive sexual life. Subsequently, linear regression models defined those characteristics, attitudes and behaviours associated to these risk habits. School and sexual experiences as well as family characteristics and relations with parents result to be significantly associated to risk habits

Multiple factor analysis for time-varying two-mode networks

Most social networks present complex structures. They can be both multi-modal and multi-relational. In addition, each relationship can be observed across time occasions. Relational data observed in such conditions can be organized into multidimensional arrays and statistical methods from the theory of multiway data analysis may be exploited to reveal the underlying data structure. In this paper, we adopt an exploratory data analysis point of view, and we present a procedure based on multiple factor analysis and multiple correspondence analysis to deal with time-varying two-mode networks. This procedure allows us to create static displays in order to explore network evolutions and to visually analyze the degree of similarity of actor/event network profiles over time while preserving the different statuses of the two modes

Contributo alla validazione della versione italiana della scala del Social Support di Susan Harter

Scopo del presente lavoro è proporre una versione italiana della Social Support Scale for adolescents di Susan Harter (1985) e di testarne le proprietà psicometriche. La scala permette di valutare il grado di supporto sociale percepito dal soggetto e la considerazione che sente di riceve da parte di altri significativi. La versione italiana è stata somministrata, in fase di pre-test, a 80 soggetti. I rilievi emersi hanno condotto ad alcuni adattamenti; la versione così ottenuta è stata somministrata ad un campione di 1203 soggetti (11-18 anni). Le analisi statistiche hanno consentito di verificare la consistenza interna e la struttura fattoriale della scala. Tali analisi hanno confermato l’attendibilità e la validità della versione italiana rispetto allo strumento originario. È stato inoltre realizzato un modello di Equazioni Strutturali, al fine di verificare la presenza di una struttura fattoriale sovrapponibile a quella originaria proposta dalla Harter. I rilievi emersi sembrano indicare che anche la versione italiana della scala proposta rappresenta un utile strumento per la comprensione e lo studio del supporto che l’adolescente percepisce di ricevere da parte di altri significativi. SUMMARY. In this paper we aim to propose an Italian version of the Social Support Scale for adolescents of Susan Harter (1985) and to explore its psychometric properties. The Social Support Scale allows to estimate the subject degree of perceived social support and the consideration from significant others. The Italian version was administered, in pre-test phase to 80 subjects. The results lead to some adaptations and this version was administered to a sample of 1203 subjects (11-18 years). The statistical analyses verified the internal consistency and the factorial structure of the Italian version with respect to the structure of the original scale. It was performed a Structural Equations modelling, to assess the properties of factorial structure. These results seem to indicate proposed Italian version of Social Support Scale can be a useful instrument to study the support that the adolescent perceives to receive from significant others

investigating social support patterns of single mothers from a social network perspective

AbstractIn the present study, we discuss how social network analysis approach can be fruitful exploited to study social support within family studies. An ego-centred network approach is adopted within a case study about social support networks of low income single mothers living in a city of southern Italy. We address three main issues. First, we aim to describe and explore the structure of social relationships that single mothers activate in order to obtain different kind of supports. Second, we investigate the main factors that affect the amount and variety of resources embedded in the single mothers' support networks. Third, we analyse the relationship between the received social support embedded in the ego network and the support perceived by mothers. Beyond the description of composition and structure of ego-centred networks through network measures and factorial methods, a series of regression models was estimated to assess factors explaining received and perceived support of single mothers

Un approccio di rete all'analisi delle relazioni amicali dei disoccupati nella città di Napoli

Several studies highlight that the labour market entry is strongly influenced by informal relational networks (friendship and kinship). Given that informal networks have a relevant role in job position, the present work deals with the analysis of the relationship between social and occupational segregation in the labour market context. Starting from a panel survey on 506 unemployed people (and informal economy workers) enrolled in the database of the Labour Agency of Scampia in Naples, we define a network structure. In particular, the analysis of the affiliation matrix, where professional profiles related to undeclared works of officially unemployed people are the nodes and professional profiles of their three most important friends are the events, is performed to identify the underlying dimensions of the joint factorial map defined by both actors and events
