Menopause and sexual desire: the role of testosterone

The present short review underlines the role of testosterone (T) in the motivational and satisfaction components of women's sexuality and critically discusses the strategies to treat hypoactive sexual desire disorder (HSDD), a condition of low desire associated with personal and/or interpersonal difficulties, which is more common in surgical menopausal women. There are multiple ways androgens target the brain regions (hypothalamic, limbic and cortical) involved in sexual function and behaviour. Even though circulating available androgens have been implicated in several domains of sexual response, they seem to be related weakly to symptoms, such as low sexual desire, poor sexual arousal, orgasm and diminished well-being in postmenopausal women. The possibilities of treating low sexual desire/HSDD are multifaceted and should include the combination of pharmacological treatments able to maximize biological signals driving the sexual response, and individualized psychosocial therapies in order to overcome personal and relational difficulties. Transdermal T has been shown to be effective at a dose of 300 μg/day both in surgically and naturally menopausal women replaced with estrogen or not, without any relevant side-effects. However, the decision to treat postmenopausal women with HSDD with T is mainly based on clinical judgement, after informed consent regarding the unknown long-term risks.     

Reconsidering two-agent Nash implementation

In this paper, we reconsider the full characterization of two-agent Nash implementation provided in the celebrated papers by Moore and Repullo (Econometrica 58:1083–1099, 1990) and Dutta and Sen (Rev Econ Stud 58:121–128, 1991), since we are able to show that the characterizing conditions are not logically independent. We prove that an amended version of the conditions proposed in these papers is still necessary and sufficient for Nash implementability. Then, by using our necessary and sufficient condition, we show that Maskin’s impossibility result can be avoided under restrictions on the outcomes and the domain of preferences much weaker than those previously imposed by Moore and Repullo (Econometrica 58:1083–1099, 1990) and Dutta and Sen (Rev Econ Stud 58:121–128, 1991).     

Exploring the Link between Mindfulness and Relationship Quality: Direct and Indirect Pathways

This study serves to advance the empirical research on predictors of relationship quality by considering the role of trait mindfulness in combination with measures of stress and positive relationship behaviors among a diverse sample of men and women in couple relationships. Multi-group structural equation models tested both direct links and indirect pathways and found stronger evidence for an additive model of trait mindfulness, perceived stress, and positive couple behaviors uniquely associated with men's and women's reports of relationship quality. Furthermore, positive relationship behaviors are comparatively the most closely linked with relationship quality for both men and women in our sample. As more clinicians are incorporating mindfulness training with clients, these types of explorations can serve to inform practices on relative value of intervention strategies and possible pathways for enhancing couple relationship quality.     

Pool size and the sustainability of optimal risk-sharing agreements

We study a risk-sharing agreement where members exert a loss-mitigating action which decreases the amount of reimbursements to be paid in the pool. The action is costly and members tend to free-ride on it. An optimal risk-sharing agreement maximizes the expected utility of a representative member with respect to both the coverage and the (collective) action such that efficiency is restored. We study the sustainability of the optimal agreement as equilibrium in a repeated game with indefinite number of repetitions. When the optimal agreement is not enforceable, the equilibrium with free-riding emerges. We identify an interesting trade-off: welfare generated by the optimal risk-sharing agreement increases with the size of the pool, but at the same time the pool size must not be too large for collective choices to be self-enforcing. This generates a discontinuous effect of pool size on welfare.     

International migrations and care provisions for elderly people left behind. The cases of the Republic of Moldova and Romania

International migrations are posing numerous challenges to care systems in both sending and receiving countries. Based on a multi-method research conducted between 2011 and 2013, this article looks at how the care provisions for elderly people are rearranged in two Eastern European countries affected by the care drain phenomenon (the Republic of Moldova and Romania). The author charts and compares how transnational families, but also the other facets of the care diamond, such as the public sector, the market and the not-for-profit sector, provide care to elderly people left to cope at home alone because their close relatives have migrated. The main findings of the article are that transnational families are the principal welfare provider for elderly people left behind, while there is a serious delay in the adoption of specific policies for the elderly.     

The Relation Between Participatory Social Practices and Social Representations of Citizenship in Young Adulthood

The concept of citizenship is used both as a synonym of social action when referencing to an active form of citizenship as well as to indicate a form of civic obligation (formal citizenship). According to these premises, citizenship can be formalized in a large number of activities that contribute to building it in different ways. The aim of the present work is to explore how the concepts of citizenship and being a citizen are co-built by Italian young adults. Two groups of young adults are considered (engaged vs. not engaged). Eighty-nine young adults participants aged 18–36 completed a self-administered mixed-method questionnaire. A content and thematic analysis was conducted and a composite representation of citizenship emerged. Results of the present work can clarify the concept of citizenship by exploring how it is cognitively and socially represented in young adults and how this representation changes in engaged and not engaged young adults.

A Hierarchical Model for Analysing Consumption Patterns in Italy Before and During the Great Recession

The paper aims to explore how the Great Recession of the twenty-first century has impacted on the consumption behaviour of Italian households. Following a hierarchical approach, the study investigates differences in consumption behaviour at both household and regional levels. Using micro data on Italian Household Expenditure for the years 2002, 2006, 2010 and 2012, multilevel and two-step regression models have been estimated. The analysis has been performed for four different consumption categories: food, housing, work-related and leisure. The analysis reveals that the economic crisis led to increasing income elasticity for each category of consumption, especially for food, the most essential basic good. The crisis also created more marked regional disparities in the average level of expenditure.     

Newborns' Face Recognition: The Role of Facial Movement

This study investigates the role of dynamic information in identity face recognition at birth. More specifically we tested whether semi‐rigid motion, conveyed by a change in facial expression, facilitates identity recognition. In Experiment 1, two‐day‐old newborns, habituated to a static happy or fearful face (static condition) have been tested using a pair of novel and familiar identity static faces with a neutral expression. Results indicated that newborns manifest a preference for the familiar stimulus, independently of the facial expression. In contrast, in Experiment 2 newborns habituated to a semi‐rigid moving face (dynamic condition) manifest a preference for the novel face, independently of the facial expression. In Experiment 3, a multistatic image of a happy face with different degrees of intensity was utilized to test the role of different amount of static pictorial information in identity recognition (multistatic image condition). Results indicated that newborns were not able to recognize the face to which they have been familiarized. Overall, results clearly demonstrate that newborns' face recognition is strictly dependent on the learning conditions and that the semi‐rigid motion conveyed by facial expressions facilitates identity recognition since birth.
