Accuracy of the judgment of facial expression of emotions as a function of sex and level of education

The purpose of this study is to examine the recognition of facial expressions of six emotions as a function of sex and level of education (high school, college, university) of the subjects. Three hundred French-speaking citizens of Quebec had to judge which emotion was expressed in various facial stimuli presented on slides. Results show that overall, the recognition of emotions was very good. However, there were significant and strong differences between emotions and sex and levels of education did not have strong effects on the results.This research was supported by grant EQ-1717 from Fonds FCAC (Gouvernment du Quebec).     

Validation of Fear of Partner Scale

Therapists have a responsibility to ascertain if psychological aggression, physical aggression, sexual aggression exist, and if there is fear of the partner. A fear of partner measure was evaluated in 100 couples who sought relationship feedback. Fear of partner's psychological, physical, and sexual aggression was related to actual reports of such behavior. For both men and women, fear of speaking in front of partner and fear of being in therapy with partner were related to reports of psychological aggression perpetrated by the partner, dominance, and isolation by the partner, and one's own marital dissatisfaction. Among respondents who were aggressed against, more men than women reported fear of participating in therapy with their partner. The measure herein can be used to determine the extent of fear of aggression by partners and to assist in the decision‐making about the appropriateness of marital therapy and divorce mediation.     

Predictors of Substance Use and Mental Health of Children of Divorce

Abstract

This short-term longitudinal study examined psycho-social influences on substance use and mental health among children of divorced parents. The sample consisted of ethnically diverse fifth and sixth grade students, and compared children of divorced parents (CODPs; N = 176), who were an average of four years post-divorce, with children of married parents (COMPs; N = 213) who had never divorced. CODPs reported more life stress, less problem-focused coping, and more substance-using friends and family members than COMPs. Further, these variables were significantly related to CODPs' greater reported substance use, aggressive behavior, and depression than COMPs cross-sectionally, and longitudinally, four months later. The results suggest the importance of including both substance use and mental health outcomes in preventive interventions for CODPs.

Theoretical Comparisons of Forms of Exchange

A recent program comparing negotiated and reciprocal forms of social exchange offers important implications for theory development. Results of these investigations show that the form of exchange studied—negotiated or reciprocal—affects many of the processes and assumptions underlying contemporary theories of exchange. Three such effects are discussed here. First, the form of exchange affects the causal mechan– isms underlying power use and the relation between network structure and power. Second, whether exchange is negotiated or reciprocal affects the relative emphasis on learning or rational–choice models and the breadth of motivations assumed for "self–interested" actors, including reward maximization, loss avoidance, and reciprocity. Third, the form of exchange affects the salience of the cooperative and competitive "faces" of exchange, influencing actors' subjective xperiences with exchange. These results show the limitations of theories based on any single form of exchange and the need for greater understanding of the full range of exchange forms that characterize social life.     

Assessment of the Familial Relationships of Young Adult Children of Separated Parents

The aim of this work was the psychometric study of six scales designed to assess the familial relationships of young adult children of separated parents. The analyzed constructs are interparental conflict, loyalty conflict, coalition, parentification, children's perceptions of the parent–child relationships, and young adult perception of the separation–individuation process. Internal consistency and factorial validity was studied through a sample of 535 Spanish young adults from disrupted and nondisrupted families who were between 20 and 30 years old. The confirmatory factor analyses showed a certain acceptability of the original structures of all scales, with Bentler–Bonett Nonnormed Fit Index, Bentler–Bonett Normed Fit Index, and comparative fit indexes above .90 in all cases, and root mean square error of approximation below .05 in the multifactorial scales and slightly higher in the unifactorial ones. The internal consistency values were between .89 and .94 in the unifactorial scales, and between .70 and .92 in the multifactorial ones. The estimations found for the factor saturation supported the acceptability of the original structures. It is concluded that all the scales within this set present acceptable properties, in terms of dimensionality and internal consistency. The limitations are pointed out.     

An Assessment of the Psychometric Properties of Italian Version of CPGI

The aim of this study was to adapt to the Italian context a very commonly used international instrument to detect problem gambling, the canadian problem gambling index (CPGI), and assess its psychometric properties. Cross-cultural adaptation of CPGI was performed in several steps and the questionnaire was administered as a survey among Italian general population (n = 5,292). Cronbach’s alpha reliability coefficient was 0.87 and can be considered to be highly reliable. Construct validity was assessed first by means of a principal component analysis and then by means of confirmatory factor analysis, showing that only one factor, problem gambling, was extracted from the CPGI questionnaire (an eigenvalues of 4,684 with percentage of variance 52 %). As far as convergent validity is concerned, CPGI was compared with Lie/Bet questionnaire, a two-item screening tool for detecting problem gamblers, and with both depression and stress scales. A short form DSM-IV CIDI questionnaire was used for depression and VRS scale, a rating scale, was used for rapid stress evaluation. A strong convergent validity with these instruments was found and these findings are consistent with past research on problem gambling, where another way to confirm the validity is to determine the extent to which it correlates with other qualities or measures known to be directly related to problem gambling. In sum, despite the lack of a direct comparison with a classic gold-standard such as DSM-IV, the Italian version of CPGI exhibits good psychometric properties and can be used among the Italian general population to identify at-risk problem gamblers.     

Mobility of students and attractiveness of universities. The case of Sapienza University of Rome

Human mobility is a complex and multifaceted phenomenon. While labour migration has been widely and deeply investigated – through theoretical and empirical analysis – other forms of mobility have received much less attention. Students' mobility is a peculiar form of temporary movement that can be considered as neither migration nor tourism. It is rapidly growing: in the period 1975–2005 the number of tertiary education students abroad increased fourfold, from 0.61 million to 2.73 million, following the trend of the internationalization of economy and globalization of culture. In 2009 almost 3.7 million tertiary students were enrolled outside their country of origin, an increase of more than 6% from the previous year.

In this paper we analyse the international mobility of university students, using a unique data set built through surveys conducted at the Sapienza University of Rome. The data collected cover a rich array of information on students' characteristics and backgrounds, provenance places, family conditions, individual aspirations, and job preferences. The empirical analysis of those data offers an opportunity for understanding a relevant part of mobility decisions of (prospective) highly qualified workers. The Sapienza University, moreover, is at present the largest university in Europe for number of students and a pole of attraction for both European and non-European students. This allows us to enlarge our analysis at a global level.
