Clustering to reduce regional heterogeneity: A spanish case-study

Statistical methods of dimension reduction and classification are used to obtain homogeneous local-area clustering with regard to the most relevant demographic parameters. The dimension reduction is conducted in two stages using Principal Component Analysis and a modified k-mean procedure is proposed to determine the final clusters. This clustering will be useful in future demographic studies at a local level, in particular to obtain forecasts of demographic rates and population projections. The region of Castile and León in Spain is used to illustrate the method. A Poisson model is used to explore the advantages of the new clustering over the more conventional classification based on provinces.

The Role of Declarative Pointing in Developing a Theory of Mind

It has been suggested that the child's capacity to represent and influence another person's attentional state about an object or event in triadic interactions (declarative communication) is an early manifestation of social understanding in the second year of life. This study tested the following predictions: First, in typically developing children declarative pointing emerges later than imperative pointing. Second, the capacity to use declarative pointing is linked to the understanding of other's intentions (i.e., to the capacity to reproduce other's intended acts after seeing failed attempts to perform these acts). The study was conducted in 2 phases. In the first phase, the parents of 133 typically developing infants completed the Questionnaire on Pointing Gesture, which allowed the identification of babies able to use pointing in familiar contexts. Of these children, 40 participated in the experiment and were tested on 2 tasks: a new task designed to elicit production and comprehension of imperative and declarative pointing, and a modified version of Meltzoff's (1995) task designed to assess understanding of others' intentions. Tasks were administered to each participant in 2 sessions carried out at 3‐month intervals. Children were 12 months old on average at the 1st session and 15 months old on average at the 2nd session. Results showed that children produced and understood declarative pointing later than imperative pointing. Furthermore, production of declarative pointing was clearly linked to understanding of others' intentions. No relation was found between production and comprehension of imperative pointing and intention understanding. Implications from the association between declarative pointing and inferring other's intentions are discussed.     

Moving communities: A process of negotiation with a Gypsy minority for empowerment

This paper describes the process by which the relationship between university workers and members of a Gypsy community evolved. Transformation in the relationships between the two, in terms of knowledge, trust, and affect, in turn transformed the nature of the work undertaken. What started as research on the community changed into research within and of the community. The process is discussed in terms of empowerment, community psychological practice and participatory action research. Este artículo describe el proceso de cambio de la relación establecida entre miembros de una universidad y miembros de una comunidad gitana. Las transformaciones que dicha relación experimentó, en términos de conocimiento, confianza y afecto, acabaron alterando la naturaleza del propio proyecto. Lo que empezó siendo una investigación sobre una comunidad, fue transformándose en una investigación en la comunidad, con la colaboración de la comunidad. El artículo discute este proceso se discute en términos de 'empowerment', psicología comunitaria, e investigación-acción.     

What Coy Smiles Say About Positive Shyness in Early Infancy

Positive shyness is a universal emotion with the specific social function of regulating our interactions by improving trust and liking, and showing politeness. The present study examined early infant production of coy smiles during social interactions as a measure of positive shy behavior. Eighty 4‐month‐olds were experimentally observed during three types of interactions in front of a mirror in which (1) the infant only sees him or herself, (2) the infant only sees the other person (mother, father, or stranger), and (3) the infant sees both him or herself and the other person. Infants produced more coy smiles during the interaction with a stranger than during the interactions with their mother or their father, or when they could see only themselves in front of a mirror. Infants also produced more coy smiles when they could see their self‐reflection during the interaction than when they could not. Our results support the assumption that coy smiles indicate an early emerging emotional reaction with an important adaptive function during social situations involving novel persons and when special attention is given to the child.     

Emerging adulthood among former system youth: The ideal versus the real

Recent research has indicated that emerging adulthood, the late teen years and early twenties, is a distinct developmental period, which occurs gradually and is often filled with exploration, stress, uncertainty and a lack of a distinct role in life. Few studies, however, have examined how emerging adulthood tenets are experienced by young people involved with social service systems. With this in mind, fifty-nine young adults, ages 18 to 25, participated in in-depth interviews regarding their perspectives on transitioning to adulthood and adulthood. Participants were struggling with emotional difficulties, and shared a childhood history, which included a mood disorder diagnosis and utilization of public mental health and social services (e.g., child welfare, juvenile justice, and/or public welfare). The study sought to understand whether or not young adults with mental health and social service histories experience similar (or different) dimensions of mainstream emerging adulthood developmental theory during the late teens and early twenties. Theoretical thematic analysis indicated support not only for the theory of emerging adulthood, but also aspects unique to this sub-population. Implications for practice, policy and research are discussed.     

Caregiver Leave-Taking in Spain: Rate,Motivations, and Barriers

This paper aims to (1) determine the rate of (full- and part-time) caregiver leave-taking in Spain, (2) identify the reasons conducive to a more intense use of this resource, and (3) ascertain the main obstacles to its use, as perceived by caregivers. All 896 people covered by the sample were engaging in paid work and had cared for dependent adults in the last 12 years. This resource, in particular the full-time alternative, was found to be a minority option. The data showed that legal, work-related, and family and gender norm issues are the four types of factors that determine the decision to take such leaves. The most significant obstacles to their use are the forfeiture of income and the risk of losing one’s job. Our results suggest that income replacement during a leave would increase the take-up of these resources. Moreover, enlargement of public care services would promote the use of leave as a free choice of caregivers.     

Measurement Invariance of Ryff’s Psychological Well-being Scales Across Italian and Belarusian Students

Cross-cultural researches on the Ryff’s Psychological Well-being (PWB) Scales are currently not available. The aim of the paper was to investigate the measurement invariance of the 18-item version of the PWB Scales across 1,114 high school and undergraduate Italian and Belarusian students. After identifying the six correlated first-order factors and one second-order factor model of the Ryff’s PWB Scales, as baseline model for each sample, multi-groups confirmatory factor analyses were subsequently performed. All analyses were performed using the Robust Diagonally Weighted Least Squares estimation procedures, entering a polychoric correlation matrix. Multi-groups analyses showed that factor structure of the preferred model did not change across the Italian and Belarusian samples. Although the obtained results provided a preliminary support for cross-cultural structural invariance of the PWB Scales, further investigations are required to ensure its generalizability and applicability. Limitations and suggestions for future researches as well as psychosocial applications for educational context were discussed.
