Description
Many methodological approaches have been utilized to predict student retention and persistence over the years, yet few have utilized a Bayesian framework. It is believed this is due in part to the absence of an established process for guiding educational researchers reared in a frequentist perspective into the realms of Bayesian analysis and educational data mining. The current study aimed to address this by providing a model-building process for developing a Bayesian network (BN) that leveraged educational data mining, Bayesian analysis, and traditional iterative model-building techniques in order to predict whether community college students will stop out at the completion of each of their first six terms. The study utilized exploratory and confirmatory techniques to reduce an initial pool of more than 50 potential predictor variables to a parsimonious final BN with only four predictor variables. The average in-sample classification accuracy rate for the model was 80% (Cohen's κ = 53%). The model was shown to be generalizable across samples with an average out-of-sample classification accuracy rate of 78% (Cohen's κ = 49%). The classification rates for the BN were also found to be superior to the classification rates produced by an analog frequentist discrete-time survival analysis model.

Description
Although U.S. rates of college enrollment among 18-24 year olds have reached historic highs, rates of degree completion have not kept pace. This is especially evident at community colleges, where a disproportionate number of students from groups who, historically, have had low college-completion rates enroll. One way community colleges are attempting to address low completion rates is by implementing institutional interventions intended to increase opportunities for student engagement at their colleges. Utilizing logistic and linear regression analyses, this study focused on community college students, examining the association between participation in institutional support activities and student outcomes, while controlling for specific student characteristics known to impact student success in college. The sample included 746 first-time, full-time, degree-seeking students at a single community college located in the U.S. Southwest. Additional analyses were conducted for the 440 first-time, full-time, degree-seeking students in this sample who placed into at least one developmental education course. Findings indicate that significant associations exist between different types of participation in institutional interventions and various student outcomes: Academic advising was found to be related to increased rates of Fall to Spring and Fall to Fall persistence and, for developmental education students, participation in a student success course was found to be related to an increase in the proportion of course credit hours earned. The results of this study provide evidence that student participation in institutional-level support may relate to increased rates of college persistence and credit hour completion; however, additional inquiry is warranted to inform specific policy and program decision-making at the college and to determine if these findings are generalizable to populations outside of this college setting.

Description
This research addressed concerns regarding the measurement of cyberbullying and aimed to develop a reliable and valid measure of cyberbullying perpetration and victimization. Despite the growing body of literature on cyberbullying, several measurement concerns were identified and addressed in two pilot studies. These concerns included the most appropriate time frame for behavioral recall, use of the term "cyberbullying" in questionnaire instructions, whether to refer to power in instances of cyberbullying, and best practices for designing self-report measures to reflect how young adults understand and communicate about cyberbullying. Mixed methodology was employed in two pilot studies to address these concerns and to determine how to best design a measure which participants could respond to accurately and honestly. Pilot study one consisted of an experimental examination of time frame for recall and use of the term on the outcomes of honesty, accuracy, and social desirability. Pilot study two involved a qualitative examination of several measurement concerns through focus groups held with young adults. Results suggested that one academic year was the most appropriate time frame for behavioral recall, to avoid use of the term "cyberbullying" in questionnaire instructions, to include references to power, and other suggestions for the improving the method in the main study to bolster participants' attention. These findings informed the development of a final measure in the main study which aimed to be both practical in its ability to capture prevalence and precise in its ability to measure frequency. The main study involved examining the psychometric properties, reliability, and validity of the final measure. Results of the main study indicated that the final measure exhibited qualities of an index and was assessed as such. Further, structural equation modeling techniques and test-retest procedures indicated the measure had good reliability. And, good predictive validity and satisfactory convergent validity was established for the final measure. Results derived from the measure concerning prevalence, frequency, and chronicity are presented within the scope of findings in cyberbullying literature. Implications for practice and future directions for research with the measure developed here are discussed.

Description
Maintaining sexual desire as the marriage endures is a challenge, especially as it involves the interplay of seemingly opposing tensions of novelty, autonomy, and closeness. Difficulties can arise when autonomy, which requires spousal distancing, is perceived as a martial threat and therefore suppressed. This dissertation investigates whether prosocial marital distancing can nurture autonomy and promote sexual desire.
Torah-observant Jewish married couples practice family purity, a Jewish law forbidding sexual relations during menstruation and shortly thereafter. During this time couples often avoid sleeping in the same bed, physical touch, and behaviors that can instigate a sexual encounter. These distancing restrictions are lifted when the wife immerses in a ritual bath. The process repeats at the next menstruation.
This research examined the effects of family purity’s marital distancing through two studies. The first involved qualitative interviews of family purity wives (N = 10) guided by relational dialectics theory (Baxter & Montgomery, 1996). Study one findings suggest that family purity wives navigate the three tensions of integration, expression, and certainty. Study one also revealed a new tension, the dialect of restraint. The dialectic of restraint appears to enhance marital communication, heighten the appreciation for the mundane, and help sustain sexual desire.
Study two, the quantitative phase of the research, applied self-expansion theory (Aron & Aron, 1986) to investigate differences between family purity and non-family purity couples. A sample of 90 married Jewish dyads (N = 180) participated in a cross-sectional online questionnaire. Findings suggest that while non-practicing couples report greater self-expansion, family purity couples report greater sexual closeness. Family purity couples also report the same closeness and sexual closeness ideals, whereas non-practicing couples reported divergent ideals. Non-practicing family purity husbands had the greatest reported discrepancy between ideal and actual sexual closeness.
The combined findings suggest that sanctioned prosocial distancing as practiced by family purity couples enables the integration of cognitive growth and mitigates the threat of autonomy. Prosocial distancing within the family purity marriage appears to provide the wife space for autonomy that in turn provokes novelty and sexual desire. Findings are discussed in relation to theoretical contributions, study limitations, and future directions.
