Content validity analysis of ISD-1: an instrument for social diagnosis in care homes for older persons†

This article presents the validity study for ISD-1 (Instrument for Social Diagnosis), designed to be used in the specialist field of intervention in care homes for older persons. The study has focused on the evidence regarding the validity of its content. The definition of the operative area of ISD-1 (social diagnosis in care homes), and its representativeness and relevance, are decisive aspects for its validity. Two validation procedures were used, with the participation of two independent groups of experts. Both procedures had the objective of obtaining a quantitative measure assessing the representation of the area and of the degree of association between the dimensions and the items of the instrument. We may conclude that there is a sufficient degree of evidence for the representativeness, relevance and usefulness of the content of ISD-1, meaning it may be considered a suitable instrument for the formulation of social diagnoses in care homes for older persons.     

Automatic and location-adaptive estimation in functional single-index regression

This paper develops a new automatic and location-adaptive procedure for estimating regression in a Functional Single-Index Model (FSIM). This procedure is based on k-Nearest Neighbours (kNN) ideas. The asymptotic study includes results for automatically data-driven selected number of neighbours, making the procedure directly usable in practice. The local feature of the kNN approach insures higher predictive power compared with usual kernel estimates, as illustrated in some finite sample analysis. As by-product, we state as preliminary tools some new uniform asymptotic results for kernel estimates in the FSIM model.     

The public view of immigrant integration: multidimensional and consensual. Evidence from survey experiments in the UK and the Netherlands

Despite the growing interest in immigrant integration in a wide range of scholarly literature, there is less interest in how integration might be understood by the public. Using a survey-embedded conjoint experiment in the Netherlands and the UK, we ask the public what they think constitutes successful immigrant integration. We show that the public has a multidimensional view of integration, which goes beyond a simple preference for cultural assimilation. We discover that there is a remarkably stable hierarchy of preference of integration outcomes, which is a matter of wide spread consensus in both our countries among different social groups and people with different attitudes on immigration. Using the British data we also show an integration penalty for immigrants of non-white origins. Our article places public opinion of immigrant integration at the heart of a rapidly expanding research agenda into the social and political impacts of immigration.     

Stability and Change in Youths’ Political Interest

Political interest is a key for the survival and development of democracies. Therefore, it is important to establish when political interest develops. We examined changes in political interest—when and in which directions—among youths between 13 and 28 years of age. We followed five age groups of Swedish youths over 2 years, with a total of 2621 participants. Analysis of stability coefficients supported the idea that political interest becomes more stable with age. From their early twenties, youths’ political interest was found to be as stable as has been earlier reported for adults. Among adolescents, the lowest stability rate was observed in the youngest cohort (ages 13–15). The results also showed that, when taking the increase in political interest into account, the proportion of youths losing their interest in politics corresponded to the proportion of youths gaining interest over time. On the whole, this study brings new insights on the development of political interest over time. It provides empirical evidence on when political interest is most susceptible to change and on how it is likely to change. Implications for research and intervention are discussed.     

Working with families living with autism: potential contributions of marriage and family therapists

This article introduces marriage and family therapists (MFT) to some of the common issues faced by families that have a child with autism spectrum disorder (ASD). First, autism is defined and common myths surrounding it are discussed. Next, relational challenges are presented that families report experiencing during early childhood through the elementary school years, adolescence and the transition into adulthood, and the later years of the family life cycle. Real-life stories are included to illustrate the potential contributions that MFTs can make to families that have a child with ASD.     

A Resampling Algorithm for Chaotic Time Series

In the field of chaotic time series analysis, there is a lack of a distributional theory for the main quantities used to characterize the underlying data generating process (DGP). In this paper a method for resampling time series generated by a chaotic dynamical system is proposed. The basic idea is to develop an algorithm for building trajectories which lie on the same attractor of the true DGP, that is with the same dynamical and geometrical properties of the original data. We performed some numerical experiments on some short noise-free and high-noise series confirming that we are able to correctly reproduce the distribution of the largest finite-time Lyapunov exponent and of the correlation dimension.     

An empirical analysis of the time allocation of Italian couples: are they responsive?

The literature suggests that in Italy husbands contribute less to unpaid household work than in any other European country, while women have the lowest market employment rates. Here we examine the time allocation of Italian couples on which there are surprisingly few studies to date. We analyze simultaneously the time allocated by husband and wife to market work, childcare and housework, allowing for various interactions. We use data drawn from the Italian national Time Use Survey 2002–2003 for the analysis. We find that spousal time allocation is sensitive to personal and household characteristics, such as, in particular, education and children’s age. Evidence shows that men married to more highly educated women spend more time with their children. The husband’s own characteristics have less of an effect on women’s time allocation. We also find that patterns differ substantially between weekends and weekdays. The estimated correlations between the unobservable factors affecting the couple’s time allocation suggest that the time devoted by parents to childcare is complementary and that the time they devote to housework is substitutable across weekends and other weekdays.     

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.
