The Kids Are Online: Teen Social Media Use, Civic Engagement, and Affective Polarization
Ayla Oden & Lance Porter
Social Media + Society, July 2023 

Abstract:

Teen users outpace adults in social media use across several platforms. Though much scholarship has considered the negative effects of social media use on teen well-being, this study considers how participation on Twitter, Instagram, Facebook, and TikTok is influencing teens' political interests and behaviors. Compared to traditional resources, we find that social media use across these platforms positively correlated with political interest and civic online and offline engagement, while Twitter and Facebook use had positive relationships with affective polarization. TikTok and Instagram each correlated with higher levels of interest and civic engagement, and the platforms had no relationship with polarization. We discuss these implications and what they mean for political participation among teens online.


Effects of confidential access to oral contraception in late adolescence on work and earnings
Randy Cragun
Journal of Labor Economics, forthcoming 

Abstract:

This article uses state-specific timing of legal changes and data from the Current Population Survey and National Longitudinal Survey of Young Women to estimate effects of confidential access to the pill in late adolescence on earnings, labor force participation, and human capital accumulation over the life cycle, finding no evidence of effects. These results are contrary to past research, which imposed a restriction on the regression model that this article shows explains the past results.


Child survival and contraception choice: Theory and evidence
Joydeep Bhattacharya, Shankha Chakraborty & Minkyong Kim
Journal of Macroeconomics, forthcoming 

Abstract:

This paper asks whether increases in child survival bring down fertility and incentivize couples to switch from traditional to modern methods of contraception. Our parsimonious model predicts the answer in each case is, yes. We test these connections using household-level Demographic and Health Surveys from recent fertility transitions using arguably exogenous variation in child survival at the regional level. We find a 1% increase in ambient child survival leads to a fertility drop of 1.2%. The same raises the chance of switching to modern birth control (and sticking to it) by 0.4%. Our finding supports the notion that prevailing rates of child survival influence the effectiveness of family planning programs that promote modern contraceptive use.


Nostalgia Promotes Parents' Tradition Transfer to Children by Strengthening Parent-Child Relationship Closeness
Yige Yin et al.
Personality and Social Psychology Bulletin, forthcoming 

Abstract:

Parental tradition transfer to children is pivotal for their socialization, identity formation, and culture perpetuation. But what motivates parents to transfer traditions to their children? We hypothesized that nostalgia, an emotion strengthening interpersonal bonds, would promote tradition transfer through parent-child relationship closeness. We tested these hypotheses using cross-sectional (Studies 1 and 4), cross-lagged (Study 2 and preregistered Study 5), and experimental (Studies 3 and 6) designs. In Studies 1 to 3, nostalgia was associated with, had lagged effect on, and promoted tradition transfer. In Studies 4-6, parent-child relationship closeness mediated the link between nostalgia and tradition transfer. The findings enrich our understanding of the vertical transmission of knowledge, customs, and values, offering insight into how intergenerational bonds are reinforced and cultural heritage is maintained.


Predicting Successful Placements for Youth in Child Welfare with Machine Learning
Kimberlee Trudeau et al.
Children and Youth Services Review, forthcoming

Abstract:

Out-of-home placement decisions have extremely high stakes for the present and future well-being of children in care because some placement types, and multiple placements, are associated with poor outcomes. We propose that a clinical decision support system (CDSS) using existing data about children and their previous placement success could inform future placement decision-making for their peers. The objective of this study was to test the feasibility of developing machine learning models to predict the best level of care placement (i.e., the placement with the highest likelihood of doing well in treatment) based on each youth's behavioral health needs and characteristics. We developed machine learning models to predict the probability of each youth's treatment success in psychiatric residential care (i.e., Psychiatric Residential Treatment Facility [PRTF]) versus any other placement (AUROCs > 0.70) using data collected in standard care at a behavioral health organization. Placement recommendations based on these machine learning models distinguished between youth who did well in residential care versus non-residential care (e.g., 80% of those who received care in the recommended setting with the highest predicted likelihood of success had above average risk-adjusted outcomes). Then we developed and validated machine learning models to predict the probability of each youth's treatment success across specific placement types in a state-wide system, achieving an average AUROC score of greater than 0.75. Machine learning models based on risk-adjusted behavioral health and functional data show promise in predicting positive placement outcomes and informing future placement decisions for youth in care. Related ethical considerations are discussed.


Intergenerational Effects of Lay Beliefs: How Parents' Unhealthy = Tasty Intuition Influences Their Children's Food Consumption and Body Mass Index 
Barbara Briers et al.
Journal of Consumer Research, forthcoming 

Abstract:

Childhood obesity is a major problem worldwide and a key contributor to adult obesity. This research explores caregivers' lay beliefs and food parenting practices, and their long-term, intergenerational effects on their children's food consumption and physiology. First, a cross-cultural survey reveals the link between parents' belief that tasty food is unhealthy (Raghunathan, Naylor, and Hoyer 2006) and the use of extrinsic rewards to encourage their children to eat healthily, with adverse downstream consequences for the children's body mass indices. Next, two studies demonstrate the mechanism by which this strategy backfires, as providing extrinsic rewards ironically increases children's unhealthy food consumption, which in turn leads to an increase in their body mass indices. The final two studies demonstrate potential solutions for public policy and health practitioners, either by manipulating "unhealthy = tasty" beliefs directly or by breaking the association between these food beliefs and the use of extrinsic rewards through an intervention.
