Paradoxes of social mobility in London

We analyse social mobility in London and seek to address two paradoxes. Among people living in London, relative mobility, or social fluidity, appears to be remarkably low when compared with other regions of Great Britain. But social fluidity among people who were brought up in London is similar to that of people brought up elsewhere in Britain. This is our first paradox. Furthermore, it is widely held that social fluidity is higher among people with higher levels of education, yet, the proportion of people with a University degree is much higher among people living in London than in any other region: how is this compatible with its relatively low social fluidity? This is our second paradox. We address these puzzles and find that they are largely explained by patterns of migration into and out of London by two groups that have received little attention hitherto in studies of mobility in the capital: International migrants and people who were brought up in London but who no longer live there.     

A gender story of institutional disengagement of young adults in Latin America

Latin America is home to many young adults who are neither engaged in formal education nor work, controversially dubbed as “nini” (“ni” trabajan “ni” estudian, denoting neither working nor studying). At the same time, early union formation and parenthood are pervasive in the region. Theories pertaining to the linkage between parenthood and female labor force participation are heavily based on evidence found in the Global North, with limited research on the topic in settings with less stable family structures, such as Latin American countries. This study tests the role household structure and family formation play on institutional disengagement of young adults in 12 Latin American countries. We explore the gender dynamic of human capital stagnation by focusing on early parenthood and conjugal partnership for women and men aged 20–25. We use censuses from the Integrated Public-Use Microdata Series and country-specific linear regression models. Our results reveal that the intersection of class and gender is a major determinant of institutional disengagement in the region. Women from lower social origins who leave parental home to enter conjugal union and parenthood at younger ages are particularly at risk. This study highlights the urgency of contextualizing the interplay between work and family within the framework of regional family norms, prompting further dialogues concerning the social implications of perceived inactivity.     

The road to conventional tool use: Developmental changes in children's material engagement with artifacts in nursery school

The development of tool use in early childhood is a topic of continuing interest in developmental psychology. However, the lack of studies in ecological settings results in many unknowns about how children come to use artifacts according to their cultural function. We report a longitudinal study with 17 sociodemographically diverse children (8 female) attending a nursery school in Madrid (Spain) and their two adult female teachers. Using mixed-effects models and Granger causality analysis, we measured changes in the frequency and duration of children's object uses between 7 and 17 months of age and in the directional influences among pairs of behaviors performed by teachers and children. Results show a clear shift in how children use artifacts. As early as 12 months of age, the frequency of conventional uses outweighs that of all other types of object use. In addition, object uses become shorter in duration with age, irrespective of their type. Moreover, certain teachers' nonlinguistic communicative strategies (e.g., demonstrations of canonical use and placing gestures) significantly influence and promote children's conventional tool use. Findings shed light on how children become increasingly proficient in conventional tool use through interactions with artifacts and others in nursery school.
