    <jats:p>Baby-Led Weaning (BLW) is a new and emerging method of introducing complementary feeding in solid consistency, without the use of a spoon and entirely guided by the baby. This study aims to analyze the implementation of the BLW approach in relation to compliance with basic components and sources of information in Chilean families. Using a cross-sectional design, we assessed early nutrition, including breastfeeding and foods offered, maternal/child characteristics and sources of information on BLW among a non-probabilistic sample of mothers of children &lt;24 months who reported practicing BLW (n = 261, median age = 28 years) in Chile. We found that 57.5% of mothers reported their child ate the same food as the family, 44.1% shared ≥3 meals with the family, 84.7% offered ≥3 foods at each meal and 75.6% reported only occasionally offering food with a spoon. The majority reported obtaining information on BLW from social media (82%). Moreover, 56% had offered cookies, 32% added salt and 9% sugar in the first 2 years. Exclusive breastfeeding for 6 months related to higher odds of consuming family foods (OR = 2.45, 95% CI 1.24–4.84), while having received information from professional sources and social media related to lower odds (OR = 0.45, 95% CI 0.22–0.88 and OR = 0.31, 95% CI 0.15–0.66, respectively). Those who had appropriate weight gain had lower odds of consuming ≥3 foods in meals (OR = 0.35, 95% CI 0.13–0.96). Among mothers who reported practicing BLW with their children, we observed a wide variety of feeding habits, sources of information and low compliance with the studied components. Eating the same food as the family was the most prevalent component and social media was the main source of information on BLW.</jats:p>

    <jats:p>Adolescent suicide is a pressing problem in Chile that has not yet been sufficiently addressed, as suicide rates have stagnated in recent years. One possible explanation could be linked to the adult-centered paradigm that continues to prevail in relation to adolescent health initiatives. In light of this, programs that seek to promote youth mental health should consider incorporating adolescents in the design process using participatory methodologies, to ensure that these initiatives are well-suited for the population. In line with this recommendation, a group of seven adolescents, 13 to 20 years of age, were incorporated into a research team to actively guide the design, development, and validation of a technology-based intervention, known as Project Clan, which was piloted to reduce adolescent suicide in schools in Chile. This group was known as the “Group of Experts,” in acknowledgment of their role as experts by experience on adolescence. A qualitative case study was conducted to explore their lived experiences, through semistructured individual in-depth interviews with six members of the group. Results showed that the adolescents had a high level of interest in mental health and had experienced problems of their own or accompanied friends who were struggling, which motivated their participation in the study. They had a critical view of the previous interventions they had received through educational institutions and valued their role in the promotion of their peers' mental health through the Group of Experts. They also highlighted the importance of creating tools that complement their daily lives and provide an alternative to existing social networks, by respecting their anonymity, providing a secure place for divulgation and self-expression, and facilitating access to professional support. We conclude that programs that address issues that affect adolescents should incorporate adolescents in the decision-making and design processes to ensure the acceptability and effectivity of their interventions.</jats:p>

    Herding Friends in Similarity-Based Architecture of Social Networks
    (2020)
    Tamas David-Barrett
    <jats:title>Abstract</jats:title><jats:p>Although friendship as a social behaviour is an evolved trait that shares many similarities with kinship, there is a key difference: to choose friends, one must select few from many. Homophily, i.e., a similarity-based friendship choice heuristic, has been shown to be the main factor in selecting friends. Its function has been associated with the efficiency of collective action via synchronised mental states. Recent empirical results question the general validity of this explanation. Here I offer an alternative hypothesis: similarity-based friendship choice is an individual-level adaptive response to falling clustering coefficient of the social network typical during urbanisation, falling fertility, increased migration. The mathematical model shows how homophily as a friend-choice heuristic affects the network structure: (1) homophilic friendship choice increases the clustering coefficient; (2) network proximity-based and similarity-based friendship choices have additive effects on the clustering coefficient; and (3) societies that face falling fertility, urbanisation, and migration, are likely go through a u-shaped transition period in terms of clustering coefficient. These findings suggest that social identity can be seen as an emergent phenomenon and is the consequence, rather than the driver of, homophilic social dynamics, and offer an alternative explanation for the rise of “fake news” as a societal phenomenon.</jats:p>

    Network Effects of Demographic Transition
    (2019)
    Tamas David-Barrett
    <jats:title>Abstract</jats:title><jats:p>Traditional human societies use two of biology’s solutions to reduce free-riding: by collaborating with relatives, they rely on the mechanism of kin-selection, and by forming highly clustered social kin-networks, they can efficiently use reputation dynamics. Both of these solutions assume the presence of relatives. This paper shows how social networks change during demographic transition. With falling fertility, there are fewer children that could be relatives to one another. As the missing kin are replaced by non-kin friends, local clustering in the social network drops. This effect is compounded by increasing population size, characteristic of demographic transition. The paper also shows that the speed at which reputation spreads in the network slows down due to both falling fertility and increasing group size. Thus, demographic transition weakens both mechanisms for eliminating free-riders: there are fewer relatives around, and reputation spreads slower. This new link between falling fertility and the altered structure of the social network offers novel interpretations of the origins of legal institutions, the Small World phenomenon, the social impact of urbanisation, and the birds-of-a-feather friendship choice heuristic.</jats:p>
