Description
Dynamic Bayesian networks (DBNs; Reye, 2004) are a promising tool for modeling student proficiency under rich measurement scenarios (Reichenberg, in press). These scenarios often present assessment conditions far more complex than what is seen with more traditional assessments and require assessment arguments and psychometric models capable of integrating those complexities. Unfortunately, DBNs remain understudied and their psychometric properties relatively unknown. If the apparent strengths of DBNs are to be leveraged, then the body of literature surrounding their properties and use needs to be expanded upon. To this end, the current work aimed at exploring the properties of DBNs under a variety of realistic psychometric conditions. A two-phase Monte Carlo simulation study was conducted in order to evaluate parameter recovery for DBNs using maximum likelihood estimation with the Netica software package. Phase 1 included a limited number of conditions and was exploratory in nature while Phase 2 included a larger and more targeted complement of conditions. Manipulated factors included sample size, measurement quality, test length, the number of measurement occasions. Results suggested that measurement quality has the most prominent impact on estimation quality with more distinct performance categories yielding better estimation. While increasing sample size tended to improve estimation, there were a limited number of conditions under which greater samples size led to more estimation bias. An exploration of this phenomenon is included. From a practical perspective, parameter recovery appeared to be sufficient with samples as low as N = 400 as long as measurement quality was not poor and at least three items were present at each measurement occasion. Tests consisting of only a single item required exceptional measurement quality in order to adequately recover model parameters. The study was somewhat limited due to potentially software-specific issues as well as a non-comprehensive collection of experimental conditions. Further research should replicate and, potentially expand the current work using other software packages including exploring alternate estimation methods (e.g., Markov chain Monte Carlo).

Description
This study reports on the interrelations among several domains of gender typing (e.g., masculinity, sexualization, and sexism) as well as their relationships to self-esteem. A group of undergraduates (113 women and 54 men) between the ages of 18-42 were administered online questionnaires asking them about masculinity beliefs, internalized sexualization, sexist beliefs, and self-esteem. A positive relationship was found between masculinity beliefs and hostile sexism. Also, a positive relationship was found between sexualization through self-compromise and self-esteem. These findings differ from relationships found in adolescence, which suggests a developmental change that affects these beliefs in young adults. Implications for understanding gender development in emerging adults are discussed.

Description
Aggression is inherently social. Evolutionary theories, for instance, suggest that the peer group within which an aggressor is embedded is of central importance to the use of aggression. However, there is disagreement in the field with regard to understanding precisely how aggression and peer relationships should relate. As such, in a series of three empirical studies, my dissertation takes a relational approach and addresses some of the inconsistencies present in the extant literature. In Study 1, I examined how qualities of youth's close friendships contributed to the use of aggression, both concurrently and over time. I found that youth with large friendship networks were more aggressive, whereas those with highly interconnected friendship network decreased in aggression over time. Using a dyadic mediation model, the second study considered the precursors to aggressors' friendships with peers. Specifically, I explored aggressive youth's interactions with unfamiliar peers and assessed how the interactions that unfold affected the quality of the relationship. I found that dyads who were highly discrepant in their tendencies toward aggression failed to collaborate well with one another, and this led to less positive perceptions of one another. Whereas the first two studies concerned aggressors' relationships with their friends (Study 1) and acquaintances (Study 2), Study 3 focused on a different type of relationship – the relationship between an aggressor and his or her victim(s). In the third study, I explored how power dynamics operate within an aggressor-victim dyad and assessed whether differences in the balance of power between the aggressor and victim affected the strength of their relationship. I found that more aggressor-victim dyads were characterized by a relative balance than imbalance in power, and that power balanced dyads had stronger and more sustained aggressor-victim relationships. By taking a relational approach to the study of aggression, this dissertation has advanced extant work in the field. That is, these findings move away from the simplification and aggregation of relational constructs (e.g., relationships, friendships), and instead consider the nuances of specific types of relationships or interactions with specific peers, allowing for a better understanding of the relational nature of aggression.

Description
Segregation into own-gender peer groups, a common developmental pattern, has many potentially negative short- and long-term consequences. Understanding the social cognitive processes underlying intergroup processes may lead to a better understanding of, and a chance to improve, intergroup relations between boys and girls; however, until recently gender-typed cognitions have not received a lot of attention. Therefore, in two complementary studies, this dissertation examines developmental patterns and predictors of a particular type of social cognition, gender-based relationship efficacy (GBRE). The first study examines mean-level and interindividual stability patterns of GBRE longitudinally in two developmental periods: childhood and pre-adolescence. Specifically, the first study examined children’s and pre-adolescents’ GBRE toward own- (GBRE-Own) and other-gender (GBRE-Other) peers over a one-year period. Using a four factor repeated measures analysis of variance, the results indicated that GBRE-Own is significantly higher than GBRE-Other across both cohorts. GBRE-Other, however, increased from childhood to pre-adolescence. Stability and cross-lag effects were examined using a multi-group panel analysis and revealed that GBRE-Own and GBRE-Other were stable. Additionally, high levels of GBRE-Own led to lower levels of GBRE-Other one year later, but high levels of GBRE-Other led to higher levels of GBRE-Own. Implications for understanding segregation processes and suggestions for future research are discussed.
The second study examined potential affective/cognitive, behavioral, and contextual predictors of GBRE-Other in pre-adolescence. Several hypotheses were tested using panel models and regression analyses, but there was limited support. Results indicated that GBRE-Other predicted more positive attitudes toward other-gender peers and higher preferences for other-gender peer interaction and that, for boys, anxious attitudes toward other-gender peers negatively predicted GBRE-Other and, for girls, parental attitudes toward their children’s other-gender friendships negatively predicted GBRE-Other. The lack of significant findings in the second study should be interpreted cautiously. In general, GBRE is an important construct and more research is needed to fully understand the developmental progression and implications.

Description
The overall goal of this dissertation was to examine teacher characteristics, teachers’ beliefs, and contextual factors that may motivate teachers’ decisions to engage in high quality teacher-child interactions. I use two complementary studies to meet this goal. These two studies provide insight into several aspects of early childhood teachers’ and children’s interactions including the complexity of the conversations and teachers’ supportive practices. Findings from both studies reveal that teachers are selective in how they distribute their time and attention across various types of high-quality interactions with children. Study 1suggests that teachers’ perception of how often children interact with one another motivates their decisions to engage in high quality teacher-child interactions (i.e., facilitate children’s peer interactions). Study 2 suggests that teacher well-being, specifically teacher depression, limits the extent to which teachers engage in high quality interactions (i.e., complex conversations with children). Importantly, this dissertation also showed that teachers’ motivation for engaging in teacher-child interactions does not stem from their own characteristics or perceptions alone. In addition to these factors, contextual aspects of teacher-child interactions also appear to influence teachers’ motivation to engage in high-quality teacher child interactions. Study 1 revealed that the gender composition of the children involved in each teacher-child interaction was associated with the extent to which teachers use facilitative practices, as well as with the direction and magnitude of both quality and frequency effects on teachers’ facilitation. Moreover, Study 2 revealed that the relation between teacher depression and complex conversations is changed when teachers and children are engaged in academic activities (e.g., math, books, language) relative to play or routine activities. In both Study 1 and 2, I used a teacher-focused observational coding system. Use of this observational coding system contributes novel, objective information about teacher-child interactions, as prior work on teacher-child interactions has most often relied on teachers’ self-reports of how often they interact with students. Findings from this dissertation will contribute new knowledge about teacher and contextual classroom characteristics and teacher-child interactions that will inform efforts to promote positive teacher child interactions and, in turn, student and teacher well-being.

Description
The present study was designed to extend previous research on early adolescents' involvement in electronic aggression and victimization. A new measure for electronic victimization and aggression was created for this study in order to better assess this type of peer harassment in early adolescence. The first goal of the study was to describe young adolescents' involvement in electronic aggression and victimization by exploring the links between electronic victimization and aggression and (a) youth demographic characteristics (e.g., gender, ethnicity), (b) involvement in traditional forms of aggression and victimization, and (c) gender of the aggression/victimization context (i.e., same-sex aggressor -victim versus other-sex aggressor- victim dyad). The second goal was to examine how electronic victimization and aggression were associated with self-esteem and relationship efficacy. Participants were 826 (49.9% female) 7th and 8th grade students (M age = 12.5 years old; SD = .67). Students were administered surveys during school hours. Results indicated that girls were more likely to be involved in both electronic aggression and victimization than boys. Further, girls were more likely to be both electronic aggressors and victims simultaneously than boys. Finally, those involved with electronic aggression reported higher levels of relationship efficacy than their peers and involvement as an aggressor/victim was associated with lower self-esteem than any other involvement category.

Risk and protective factors of peer victimization: the role of preschoolers' affiliations with peers
Description
Studies of peer victimization typically focus on behavioral characteristics of the victims, and frequently overlook the role that peers may play. The current study extended previous research by examining how time spent with two types of peers (externalizing and socially competent) can serve as a risk or protective factor for preschoolers' victimization, and how victimization may differ for boys and girls. In addition, the study explored how affiliating with same-sex and other-sex externalizing and socially competent peers may differentially relate to victimization. Results showed that girls who affiliated with externalizing female peers were significantly more at risk for victimization. In addition, boys and girls who spent time with socially competent male peers (but not female peers) negatively predicted victimization. The results indicate that children's peers, in certain circumstances, may play an important role in victimization. These findings also highlight the importance of considering children's and peers' gender when studying peer processes.

Description
It has been 30 years since research has tried to determine how adults decide if an infant is male or female (Seavey et al., 1975; Sidorowicz & Lunney, 1980), with research at that time indicating that participants tended to label infants as male. The purpose of this study is to investigate whether adults today can identify infant gender above chance, and what tools adults use to assign gender labels to babies. I hypothesize that females, social science majors, students who frequently interact with children, and students who are very confident will all assign gender labels more accurately than their counterparts. I showed a video to University students featuring five sets of parents playing with their infants. The video featuring three male and two female babies was edited to remove any gender identifying information. Students were asked to guess whether each of the infants was male or female, and to explain how they came to that conclusion. One sample t-tests revealed that students overall were able to correctly identify infant gender significantly more than what would be expected due to chance for 4 out of 5 infants. The results did not support my hypothesis that social science majors or people who frequently interact with children are better at assigning gender labels. This study did find a significant correlation between confidence and accuracy. When asked to explain how participants assigned infant gender labels, I found a significant correlation between infant physical movement and correct students labeling the infant as male. There was also a significant relationship between parental voice being and participants labeling infants as female whether the infant was actually female or not. Unlike research from the late 1970's and early 1980's, college students today can accurately assign gender labels to infants. This suggests that either the conceptualization of gender in the U.S. culture has changed enough since previous research over 3 decades ago, that there is something about parent-baby play that helps people correctly identify infant gender, or both.

Description
This thesis aimed to discover the risks of being a high achieving student, in secondary school contexts. With the growing concern for college admission, the high achieving student has become more prevalent within society. This paper sought to gain deeper understanding into the risks and implications of attempting to achieve excellence for high achievers. Interviews with three frontline personnel at two college preparatory schools and one International Baccalaureate degree program were conducted. It was found that in the studied geographic location, peer pressure and relations, parental pressure, perfectionism, extra-curricular activities, college admission, mental health implications, and coping mechanisms are themes that are highlighted through interviews with primary staff of high achieving students. Although personnel at each of these secondary schools were clearly aware of the stress experienced by their students, a disparity remained between how certain programs managed the stress and how it negatively impacted students. College preparatory faculties appear to be more involved and current on their students' stress. This study was limited and further research should be conducted in the future that expands on this concept in various sociogeographic locations.

Description
The theoretical basis of the proposed study is drawn from an ecological-transactional (Lynch & Cicchetti, 1998) systems approach to development, which focuses on contexts, and correspondingly, overlays the gender affirmative model’s (GAM) transactional model of support (Keomeier & Ehrensaft, 2018) to reveal protection in the school ecology. Combining these two approaches provides unique insights into protective factors in the school ecology, distinct from developmental systems approaches driven by the minority stress model (Meyer, 2003), which are designed to highlight the multidimensional quality of risk (Eisenberg et al., 2019). The dissertation had two central aims: 1) to report on the development of the Gender Affirmative School Climate (GASC) scale, a self-report survey designed to capture high school climate specific to the domain of gender, and 2) to explore how gender affirmative school climate (GASC) relates to student self-esteem and school belongingness. Unique from risk factors approaches the central aims sought out to identify protective factors within a developmental system ecology of the high school context.In two pilot studies (N=12; N=758; trans = 413, non-trans = 344) and primary study (N=813; trans = 482, non-trans = 328) results for scale development provide evidence to validate assumptions that the proposed (GASC) construct captures what was intended, that is, school climate specific to the domain of gender. However, measurement invariance procedure showed that not all items operated equivalently across trans and non-trans groups, and confirmed that the proposed scale meets criteria for “weak measurement invariance”. High school students that reported more positive school climate reported lower self-esteem scores. Only one protective moderator was consistent with hypotheses: More feelings of similarity to peer group gender (boys) emerged as a protective factor for transgender identified high schoolers attenuating the negative relationship between perceptions of school climate and self-esteem. Latent measurement models for each gender group demonstrated that the school belongingness construct is highly related to the proposed (GASC) construct. This demonstrated domain overlap with “feelings of school belongingness” signals that the proposed scale showed good convergent validity. The results provide insight about ways high schools can be pro-active to promote a healthier school climate for transgender students.
