Learning during infancy is dependent on many factors. One such factor is physiological self-regulation. This study investigated the relationship between physiological self-regulation abilities and evidence of learning based on Visual Expectation Paradigm (VExP) performance. Alterations in High Frequency Heart Period Variability (HFHPV) assessed physiological self-regulation and were hypothesized to correspond with VExP performance. Findings revealed patterns of HFHPV change during the VExP and that HFHPV change negatively corresponded with a resting measure of HFHPV and VExP performance. Results suggested that resting HFHPV was a better predictor of learning during the VExP than patterns of HFHPV change evidenced throughout the task.

One of the significant contributions of this study is its inclusion of the role of social contextual factors in determining parenting. I built on the ecological model proposed by Belsky (1984). As such, the parenting model tested in this dissertation included individual level determinants of parenting: 1) parent characteristics (e.g., developmental history), and 2) child characteristics (e.g., behavior problems). Yet, rather than include a social context domain as described by Belsky, I distinguished between within family context (e.g., interparental hostility) and external to family context (e.g., work-family conflict, neighborhood disorganization) as social contextual sources of stress and support to the parent-child relationship. A second significant contribution of this study is attention to parent gender. I included assessments of both mother and father parenting and specifically test for hypothesized differences in how the predictive model might operate differently depending on the parent’s gender. It is important to note further that the accomplishment of this examination of parent gender involved the use of a methodology that is itself an important contribution to the existing work. Specifically, my methodology involves simultaneous testing of mother and father data, something that has not typically been done in past studies. Critically, this methodology controls for any overlap or similarity between mother and father parenting and thereby allows for a better test of the uniqueness of mother and father parenting and of patterns of predicting mother and father parenting. This study employed parent reported data from the NIMH-funded Ogden Youth and Family Project, a longitudinal, sequential-cohort study of families with adolescent children (N = 933). Using structural equation modeling, we found that the model adequately fit the data while direct and indirect effects on parenting were found. The individual level parenting determinants of child behavior problems and parental depression were significantly directly associated with parenting, particularly for fathers. The within family contextual variable of covert marital conflict was directly associated with father parenting, and directly and indirectly associated with mother intrusive parenting through maternal depression. As risk factors external to the family, workfamily conflict was not significantly related to parenting, and neighborhood disorganization was indirectly related to intrusive mothering (but not her supportive parenting or to father’s parenting), through elevated levels of marital conflict and depression.

For a generation in many sociological literatures, China has provided the example of traditional family with good intra-familial relationship, filial piety and extended family support which is unusually stable and substantially unchanged. However, with the emergence of modernity, in the forms of industrialization and urbanization; capitalization and public policy transformation, the family structure has undergone changes where nuclear and asymmetrical types have emerged. At the same time, family support for the elderly is affected by the changes in family formation, family dynamics, as well as people’s values and their way of life. Do the theories concerning the relationship between modernity and family change that have been proposed and developed by western scholars, apply to Chinese societies also? Are there any differences between Western and Chinese culture in forming family organizations during modernity? For answering these questions, this study explores the impact of modernity on family structure and changing functions in terms of family support for elderly in China. The aim is to understand why and how family change in its structure and functions within modernity. To fit the purpose and nature of this study, the exploratory strategy is used. By adopting historical review in the first stage, families in six historical stages (legendary and heroic age; Neolithic age; Xia, Shang and Western Zhou dynasty; Spring and Autumn, Warring States, Qin and the Western Han dynasty; from Eastern Han to early and middle period of Qing; and Late period of Qing until more recent years) are examined to show the “macro-transformations” and “micro-adaptive adjustments” that had happened to Chinese families in history. Then, adopting the methodological concept of invariance, multiple-case (M-C) studies in three areas in China are conducted to illustrate the Chinese families in different level of modernization, namely the agrarian pre-modern (Yunnan), the transforming-mix modern (Beijing), and the capitalist modernized (Hong Kong). Based on the survey data and from analysis of semi-structured interview with 62 respondents about their own family experiences and 8 experts about their viewpoint and explanations, there is evidence showing that corresponding structure and family support for elderly changes are aiding modernization under diverse socio-economic characteristics (i.e. under developed, developing and developed localities). To explain this phenomenon under study, a geo-adaptation model is developed from both macro and micro perspective to give insight on how modernity affects the ways of family support for elderly members. It has concluded that the development of modernity, as one of the vital reasons, contribute to changes in family structure globally (i.e. from stem and extended to nuclear and diverse form), but the care function for the aged, is not destined to deteriorate. To some extent, the Chinese tradition of filial piety and the family policy could strengthen social cohesion by maintaining the core functions once provided by the stem and extended family.

Maternity leave is a critical work-family policy that affects over two-thirds of the working U.S. female population. Although it has been studied extensively, especially since the passage of the Family and Medical Leave Act of 1993, the majority of the research has focused on White, middle-class, married, and educated working mothers. There is a plethora of information about access to maternity leave, utilization of maternity leave, length of maternity leave, and compensation during leave. However, there are several limitations in the research. A majority of studies use outdated datasets; measure family leave as a proxy for maternity leave; study paid and unpaid maternity leave as one variable; and leave out contextual factors. Using intersectionality theory as a guiding framework, which poses that women's gendered experiences are shaped by the intersection of race/ethnicity and class, the purpose of this study is to identify similarities and differences in the maternity leave practices of a racially diverse sample of working mothers. The Listening to Mothers III Survey of births occurring in 2011 and 2012 will be used for this study. Bivariate and multivariate analyses were conducted to determine the factors that predict access to leave, utilization of leave, length of leave, and compensation during leave. Results show that sociodemographic factors such as household income, poverty level, and insurance are consistent predictors of access to leave, use of leave, and length of leave. Using an intersectional approach revealed that mothers' intersectional locations can increase or decrease their chances of getting access to leave, using leave, the length of leave taken, and compensation received during leave. The results of this study show that including sociodemographic factors in maternity leave research can further our understanding of how the social characteristics of working mothers impact their maternity leave experiences. Paying more attention to these factors in maternity leave research will contribute recommendations for creating more inclusive maternity leave policies.

Current data highlight significant disparities in infant and maternal health (IMH) outcomes both when comparing outcomes to other countries and between groups within the U.S. Previous studies indicate that disparities in health outcomes are caused by health inequities. Health inequities are a result of marginalized groups historically being denied resources and exposed to increased risk directly impacting health. These resources and risks are considered social determinants of health (SDoH), such as income, housing, transportation, and access to care. Although SDoH influence individuals across multiple levels of society, communities are sites where individuals directly access protective resources and are potentially exposed to risk. Therefore, given the persistence of poor IMH outcomes and the role communities play as sites in which social factors directly impact health, this study sought to understand the relationship between local-level SDoH and IMH outcomes in Florida as well as the role local health departments play in improving outcomes. To do this, a mixed methods analysis was conducted using secondary quantitative and qualitative data. The secondary quantitative data was compiled to create a dataset for variables that represent community-level SDoH and IMH outcomes, which were all analyzed statistically and utilizing geospatial visualizations. The secondary qualitative data consisted of county-level content from Healthy Start Coalition websites as well as Community Health Needs Assessments and Health Improvement Plans. Findings suggest that there are statistically significant relationships between variables utilized to measure racial residential segregation, neighborhood deprivation, housing stability, rurality and access to care and the variables utilized to measure infant health outcomes. Further, the qualitative data suggest that less than half the sample considered IMH a priority issue. Of the counties who did, many focused on implementing strategies to impact individual behaviors, however all counties in the sample did discuss SDoH and health equity to varying degrees.
