The hypothalamus pituitary adrenal (HPA) axis and the human genome are important components of the biological etiology of externalizing disorders. By studying the associations between specific genetic variants, diurnal cortisol, and externalizing symptoms we can begin to unpack this complex etiology. It was hypothesized that genetic variants from the corticotropine releasing hormone receptor 1 (CRHR1), FK506 binding protein 51 (FKBP5), catechol-O-methyl transferase (COMT), and dopamine transporter (DAT1) genes and diurnal cortisol intercepts and slopes would separately predict externalizing symptoms. It was also hypothesized that genetic variants would moderate the association between cortisol and externalizing. Participants were 800 twins (51% boys), 88.5% Caucasian, M=7.93 years (SD=0.87) participating in the Wisconsin Twin Project. Hierarchical Linear Modeling (HLM) was used to separate the variance associated with state and trait cortisol measured across three consecutive days and trait cortisol measures were used. There were no main effects of genes on externalizing symptoms. The evening cortisol intercept, the morning cortisol slope and the evening cortisol slope predicted externalizing, but only in boys, such that boys with higher cortisol and flatter slopes across the day also had more externalizing symptoms. The morning cortisol intercept and CRHR1 rs242924 interacted to predict externalizing in both boys and girls, with GG carriers significantly higher compared to TT carriers at one standard deviation below the mean of morning cortisol. For boys only there was a significant interaction between the DAT1 variable number tandem repeat (VNTR) and the afternoon slope and a significant slope for 9/9 carriers and 9/10 carriers such that when the slope was more steep, boys carrying a nine had fewer externalizing symptoms but when the slope was less steep, they had more. Results confirm a link between diurnal trait cortisol and externalizing in boys, as well as moderation of that association by genetic polymorphisms. This is the first study to empirically examine this association and should encourage further research on the biological etiology of externalizing disorder symptoms.

ABSTRACT The present study examined the relationship between the experience of trauma during childhood (ages birth -12 years) and life satisfaction in adulthood (ages of 30-45) in a sample of convenience consisting of eight (8) adults, six (6) women and two (2) men, who volunteered to participate in this qualitative study, and self-identified as having experienced trauma between birth and age 12 years. Participants were asked to describe the trauma(s) they experienced in childhood and to discuss their thoughts and feelings about present circumstances in their lives, and how their lives have been impacted by the trauma they experienced. Data were collected via in-person interviews that were audio-taped and transcribed. The data were analyzed using a process of thematic coding. Nine (9) emotional themes were identified: aggression, anger, fear, frustration, helplessness, insecurity, irritability, loneliness and sadness. Participants reported a variety of traumas experienced, and their responses to difficult experiences were varied. Participants reported being impacted differently in eight domains of life that were examined in the study: mood related problems, self-care, social support, primary partner relationship, career, decision to have children, parenting and adult life satisfaction. All participants stated they had been impacted by early life trauma, and all stated that early-experienced trauma(s) had an impact on their life satisfaction in adulthood. Inter-coder reliability for emotional thematic codes and domains of life impacted by early trauma was .82.

Description
Children are five times more likely to be overweight at the age of 12 years if they are overweight during the preschool period, and 60% of overweight preschoolers are overweight at the age of 12 years (Matusik & Malecka-Tendera, 2011).

Children are five times more likely to be overweight at the age of 12 years if they are overweight during the preschool period, and 60% of overweight preschoolers are overweight at the age of 12 years (Matusik & Malecka-Tendera, 2011). Primary care interventions are urgently needed to improve healthy lifestyle behaviors in families. Parental influence plays an important factor in the development of healthy behaviors in children. Cognitive behavioral interventions have demonstrated preliminary success in promoting healthy lifestyle behaviors in both adults and children. Mobile technology used to supplement interventions aimed at behavior change offers an outlet to bridge gaps in health disparities and generate innovative evidence. Therefore, the purpose of this research was to establish the feasibility, acceptability, and preliminary effects of a cognitive-behavioral intervention (TEXT2COPE) synergized with mobile technology on the healthy lifestyle behaviors of parents of overweight and obese preschoolers. Primary aims of the proposed pilot study were to (a) examine the feasibility and acceptability of the TEXT2COPE program among parents of overweight or obese preschoolers with mobile phones; (b) evaluate the preliminary effects of the TEXT2COPE program on healthy lifestyle behaviors in families with overweight or obese preschoolers; and (c) evaluate the relationship among the study variables (i.e., cognitive beliefs, perceived difficulty, and healthy lifestyle behaviors). Findings indicate that this program is feasible and acceptable in this population. The intervention improved healthy lifestyle beliefs and behaviors in parents. Further supported are the interconnected relationships between parental beliefs, thoughts, and behaviors.

This dissertation employs an ethnographic methodological approach. It explores young people's performance of a New Afrikan subjectivity, their negotiation of a multiple consciousness (American, African-American, New Afrikan and Pan-Afrikan) and the social and cultural implications for rearing children of African descent in the US within a New Afrikan ideology. Young people who are members of the New Afrikan Scouts, attendees of Camp Pumziko and/or students enrolled at Kilombo Academic and Cultural Institute were observed and interviewed. Through interviews young people shared their perceptions and experiences of New Afrikan childhood. The findings of this study discuss the ways in which agency, conformity and the spaces in between are enacted and experienced by New Afrikan children. The findings particularly reveal that in one sense New Afrikan adults aid young people in examining their racial and cultural subjectivity in US America. In another sense New Afrikan adults manipulate young people into performing prescribed roles that are seemingly uncritical of the implications of these performances beyond an adult agenda.

Being properly prepared is one of the keys to surviving an emergency or a disaster. In order to be prepared, people need appropriate education in preparedness, which includes elements of prevention, and planning. There is a definite need to better prepare our nation's citizens in order for them to safely respond in times of a disaster. It also seems likely that the earlier concepts and skills are learned, the easier those concepts and skills would be to remember and the more proficient one would become in implementing them. Therefore, it seems appropriate to teach emergency preparedness concepts and skills early on in the educational process. This means that significant efforts need to be directed toward learning, what impediments currently exist, what is helpful, and how preparedness concepts and skills can be taught to our children. A survey was distributed to third, fourth, and fifth grade teachers, asking them questions about emergency preparedness lessons in the classroom. Results indicated that the majority of teachers would be willing to teach emergency preparedness if the curriculum met current academic standards and they were given adequate resources to teach this subject. This study provides ideas, concepts and motivation for teachers to use in a cross-curricular approach to teaching emergency preparedness in the classroom. This is accomplished by presenting examples of newly developed curriculum/lesson plans that meet state academic standards, based on the current Community Emergency Response Team program and on children's fiction literature for the appropriate age group. A list of literature that could be used in this development is also provided in this study.

The purpose of this study was to explore the ways in which childhood was perceived in the circuit Chautauqua movement. The methodology followed a threefold approach: first, to trace the development of the Chautauqua movement, thereby identifying the values and motivations which determined programming; next, to identify the major tropes of thought through which childhood has been traditionally understood; and finally, to do a performance analysis of the pageant America, Yesterday and Today to locate perceptions of childhood and to gain a better understanding of the purpose of this pageant. My principal argument is that the child's body was utilized as the pivotal tool for the ideological work that the pageant was designed to do. This ideological effort was aimed at both the participants and the audience, with the child's body serving as the site of education as well as signification. Through the physical embodiment and repetition of different roles, the children who participated performed certain values and cultural assumptions. This embodiment of values was expected to be retained and performed long after the performance was over - it was a form of training through pleasure.

Understanding how interpersonal relationships, such as parenting and sibling relationships, may contribute to early sleep development is important, as early sleep dysregulation has been shown to impact later sleep behavior (Sadeh & Anders, 1993), as well as cognitive and behavioral functioning (Gregory et al., 2006; Soffer-Dudek et al., 2011). In addition, twin studies provide an optimal opportunity to estimate genetic and environmental contributions to parenting, sibling relationships and child sleep, as they are influenced by both genetic and contextual factors. As such, the current thesis examined whether parental punitive discipline and sibling conflict were associated with child sleep duration, dysregulation and daytime sleepiness at 12 months, 30 months, and five years in a longitudinal sample of young twins recruited through birth records (Lemery-Chalfant et al., 2013). Mixed model regression analyses and quantitative behavioral genetic models (univariate and bivariate) were conducted to explore bidirectional relations and estimate genetic and environmental contributions to parental punitive punishment, sibling conflict and child sleep parameters. Sleep duration and dysregulation showed stability over time. Parental punitive discipline did not predict concurrent or future sleep parameters, nor were there bidirectional relations between punitive discipline and child sleep behaviors. Greater sibling conflict at five years was associated with shorter concurrent child sleep duration and greater daytime sleepiness, suggesting that sibling conflict may be a critical interpersonal stressor that negatively impacts child sleep. Shared environmental factors also accounted for the greatest proportion of the covariance between sibling conflict and sleep duration and daytime sleepiness at five years. These findings hold promise for sleep and sibling interaction interventions, including educating parents about fostering positive sibling relations and teaching caregivers to utilize specific parenting behaviors that may encourage better child sleep behaviors (e.g., establishing bedtime routines). Future studies should aim to understand the nuances of associations between family relationships (like punitive discipline and sibling conflict) and child sleep, as well as other explore person- and family-level factors, such as child negative emotions and parenting, that may influence associations between family relationships and child sleep.

Adolescent mental health problems are predicative of future problems such as depression, anxiety, ADHD, compulsive disorder, and substance use. Previous studies show that in emerging adulthood, the high prevalence and associated burdens of psychopathology increase vulnerability to disorders. These diagnoses are less common but are more severe and chronic (Tanner et al., 2009). The causes of these disorders are still being explored with recent studies showing that these mental health problems are genetically influenced. This makes understanding which gene that corresponds to what biological system is important in determining mental health. From recent studies, genes that code for calcium channels are good candidates for mental health problems. These voltage-gated channels are important mediators for physiological functions in the central nervous system and their activation provides unique responses within the brain. In a previous study, it supports the association of polymorphisms in calcium and potassium channels with the genetic risk for bipolar disorders and other mental illness (Imbrici et al., 2013). The purpose of the study was to examine if calcium channel genes influence childhood psychiatric symptoms. The first goal of this study was to form a polygenic risk score representing genetic influence on calcium channels. The second goal was to use this risk score in genetic association analyses to understand genetic risk for childhood psychopathology. Overall, the study did accomplish the goal as a polygenic risk score was created and was used to examine genetic association with child psychopathology. Based on the results, the polygenic risk score was not correlated with either parent or child- reported symptoms; however, results did show that disorders were related to each other and differed by race.

The purpose of this study was to determine the relationship between extracurricular activities and self-regulation in 400 five year old twin children. Extracurricular activities were assessed using the Health and Behavior Questionnaire, and self-regulation was assessed using the Children's Behavior Questionnaire. While there initially was a significant correlation between extracurricular activities and self-regulation, that correlation became non-significant when controlling for SES and sex in a mixed model regression model. Nearly all of the children who did not participate in extracurricular activities came from lower SES families, leading to a lack of a "control group" for the high SES families. When only taking into account the lower SES half of the sample, the correlation between extracurricular activities and self-regulation became stronger and the correlation between SES and self-regulation became non-significant. Extracurricular activities do appear to promote self-regulation in children coming from low SES families, yet their effects on children coming from high SES families is still unknown.

ABSTRACT



In this study, I analyze the construction of childhood and nature in a number of Korean Theatre For Young Audience (TFY) works and family movies produced since 2000. Studying The Tale of Haruk, Gamoonjang Baby, Oseam and The Way Home, I explore the childhood memes that surface in the analysis and how they relate to dominant cultural understandings of Korean childhood. Both nature and childhood are metaphorical spaces reflecting the specificity of the cultural context in which they are situated. And in the works I explore, the two are paired in interesting and complex ways and for ideological reasons, the study of which produces a deeper understanding of the construction of Korean childhood. The “child" in Korean TFY has not been thoroughly explored in earlier scholarly work, nor do many preceding studies explore the performance texts of Korean TFY from an analytic stance. This is a serious gap in the literature, considering the significance of the discourse on childhood as a major conceptual framework bolstering TFY and the centrality of the performative aspect of the field. Thus, this study is meaningful as one of the first doctoral works to analyze the performance texts of Korean TFY and the first work to explore Korean TFY from a childhood studies framework. The findings of this interdisciplinary work will be of interest to the field of childhood studies and TFY, broadly defined. In studying the works, my main methodology has been detailed performance analysis. Through the analysis, interesting tropes of Korean childhood emerge, some of which have not been addressed explicitly before. My work reveals Korean childhood as a hybrid cultural assemblage reflecting the complexity of the Korean cultural context, where historical, current, native and foreign ideas about childhood mingle.
