Brain Emotion Systems,Personality, Hopelessness,Self/Other Perception,and Gambling Cognition: A Structural Equation Model

The aim of this study was to explore the relations between gambling, brain emotion systems, personality, self/other perception, and hopelessness in an Italian community. Dimensions of gambling, positive and negative emotions, self/other perception, personality and hopelessness were assessed in a community sample of 235 adults aged 19–59 years. Two structural models were tested. We found a significant correlation between problem gambling and impulsivity, which in association with aggressivity and negative personality dimensions may help explain the psychopathology factor, i.e. a latent variable involving neurotic personality, hopelessness, high sensation seeking, low metacognitive responsiveness, and disorganized patterns of interpersonal relationships. These results contribute to develop a theoretical framework of gambling in relation with personality factors and provide a new approach for clinical intervention of problem gambling that relies on a solid multidimensional perspective.     

Citalopram-Associated Gambling: A Case Report

Pathological gambling behaviour is a side effect of dopaminergic drugs used in Parkinson’s disease, but has seldom been reported with selective serotonin reuptake inhibitors. A 58-years-old woman with somatisation disorder since the age of 20 and recent-onset major depression (at 54 years) received 40 mg/day intravenous citalopram, thereafter switching to the same dose of oral citalopram to treat her comorbid psychiatric disorders after showing poor response to paroxetine for one year. Her anxious and depressive symptoms were moderately reduced after 7 months of oral citalopram, but simultaneously, the patient admitted gambling. We gradually discontinued citalopram and introduced pregabalin and alprazolam; this was followed by a reduction of gambling compulsions, but the somatisation and depressive symptoms did not further improve. Pathological gambling may be mediated by an interplay of 5-HT_1A serotonergic and D₂ dopaminergic mechanisms. Citalopram affects both these mechanisms in areas that were shown to be involved in gambling behaviour, but while dopaminergic effects of citalopram appear to be consistent with the induction of gambling, its serotonergic mechanisms are rather inconsistent. In our patient, mood destabilisation induced by citalopram may have contributed to the first onset of pathological gambling.

‘I'm not like all these Ecuadorians’. Promises and dilemmas of immigrants’ selective ethnicity appropriation

This article revisits my translocal ethnography of Ecuadorian immigration to Italy, building on the notions of ethnicization and selective ethnicity appropriation. The salience of an ethnic dimension, in the daily lives of the migrants I met, is explored with regard to collective identification, alignment with co-nationals and interactions with natives. By de-constructing migrants’ ethnicity from within, a range of expectations and strategies towards the receiving society emerges. While processes of ethnicization affect them in cognitive, discursive and practical terms, immigrants selectively draw from their ethnicity patterns, as their previous identities and lifestyles interact with the mainstream overseas. Their ethnicity – as a shared repertoire of habits, ways of life and common sense ideas, supported by a communal identity and background – can be purposefully negotiated in several respects, as they strive to negotiate better life conditions overseas. Why this occurs, under what conditions, and producing what effects, are the questions to be approached in this article. As I shall argue, ethnicity-related attitudes and behaviours raise opportunities and dilemmas both for migrants’ incorporation overseas and for their transnational connections.     

A Note on Two-Way ECM Estimation of SUR Systems on Unbalanced Panel Data

This article considers the two-way error components model (ECM) estimation of seemingly unrelated regressions (SUR) on unbalanced panel by generalized least squares (GLS). As suggested by Biørn (2004 Biørn , E. ( 2004 ). Regression systems for unbalanced panel data: a stepwise maximum likelihood procedure . Journal of Econometrics 122 : 281 – 291 . [Google Scholar]) for the one-way case, in order to use the standard results for the balanced case the individuals are arranged in groups according to the number of times they are observed. Thus, the GLS estimator can be interpreted as a matrix weighted average of the group specific GLS estimators with weights equal to the inverse of their respective covariance matrices.     

A New Proposal to Gauge Intergenerational Mobility: Educational Mobility in Europe as a Case Study

This paper is aimed at presenting a new intergenerational mobility index that (a) combines the intergenerational elasticity and the R-squared of the intergenerational regression and (b) enables the expression of the total degree of mobility as the weighted sum of mobility with respect to both parents. As a case study, we apply our proposal to investigate the intergenerational mobility of education in several European countries and its changes across birth cohorts. The results derived from the proposed index indicate that Nordic countries display higher levels of educational mobility than Southern countries, whereas continental countries are in an intermediate position. Moreover, it appears that the degree of mobility increases over time only in those countries with low initial levels and remains stable for the most mobile countries. Finally, for most of the countries the proposed methodology can prove that the degree of educational mobility with respect to each parent tends to converge to the same level over the course of time.

Homemaking in the public. On the scales and stakes of framing,feeling, and claiming extra-domestic space as “home”

This article reviews the emerging literature on the negotiation of home-related feelings, claims, and practices in the public urban sphere, under the rubric of homemaking in the public. This contributes to a better sociological understanding of home and illuminates long-debated societal questions such as the interaction between majority and minority groups and the shifting boundaries between what is (regarded as) public or private. While home has traditionally been understood as a private and domestic matter, it also has a major public significance. As a category of analysis, it reveals how supposedly domestic attitudes, routines, and practices are scaled up into the public domain. As a category of practice, it is a powerful discursive resource for contentious politics in the extra-domestic domain. Who is entitled and legitimated to claim a public space as “home”, and what this implies for inter-group categorizations and relations, are questions that deserve original and comparative analysis in sociology. Processes of domestication of the public sphere, of mutual interaction between public and private life realms, and of claims-making on various scales can be fruitfully revisited along these lines, by advancing an original research agenda on the ways of framing, feeling and claiming public space as home.
