Description
In this study, potential differences in the manifestation and rates of eating disorders and symptoms (body dissatisfaction, weight and shape concerns, food restriction, and compensatory behaviors) in college women across sexual orientations were examined. The sociocultural model of eating disorders was also examined for these women across sexual orientations. The participants were organized into three different sexual orientation groups for analysis: heterosexual (group 1), bisexual, pansexual, and polysexual (group 2), and lesbian, gay, queer, transsexual, asexual, and other (group 3). Using cross-sectional data, it was revealed that there were significant group differences when comparing the three sexual orientation groups on loss of control over eating, but no significant group differences on body dissatisfaction, thin ideal internalization, and weight-related eating pathology, and total eating disorder symptoms scores. The sociocultural model was not predictive of eating disorder symptoms among non-heterosexual groups. Longitudinal analyses revealed that the sociocultural model of eating disorders prospectively predicts eating disorder symptoms among heterosexual women, but not non-heterosexual women. Both cross-sectional and longitudinal analyses indicate that non-heterosexual women may be protected from societal pressure to subscribe to the thin ideal and its subsequent internalization. However, the comparison group of heterosexual women in our study may not have been completely representative of undergraduate women in terms of total eating disorder symptoms or eating pathology. Additionally, regardless of sexual orientation, our sample reported more total eating disorder symptoms and emotional eating than previous studies. These findings have both clinical and research implications. Future research is needed to determine what risk factors and treatment target variables are relevant for non-heterosexual women.

Description
Company X has developed RealSenseTM technology, a depth sensing camera that provides machines the ability to capture three-dimensional spaces along with motion within these spaces. The goal of RealSense was to give machines human-like senses, such as knowing how far away objects are and perceiving the surrounding environment. The key issue for Company X is how to commercialize RealSense's depth recognition capabilities. This thesis addresses the problem by examining which markets to address and how to monetize this technology. The first part of the analysis identified potential markets for RealSense. This was achieved by evaluating current markets that could benefit from the camera's gesture recognition, 3D scanning, and depth sensing abilities. After identifying seven industries where RealSense could add value, a model of the available, addressable, and obtainable market sizes was developed for each segment. Key competitors and market dynamics were used to estimate the portion of the market that Company X could capture. These models provided a forecast of the discounted gross profits that could be earned over the next five years. These forecasted gross profits, combined with an examination of the competitive landscape and synergistic opportunities, resulted in the selection of the three segments thought to be most profitable to Company X. These segments are smart home, consumer drones, and automotive. The final part of the analysis investigated entrance strategies. Company X's competitive advantages in each space were found by examining the competition, both for the RealSense camera in general and other technologies specific to each industry. Finally, ideas about ways to monetize RealSense were developed by exploring various revenue models and channels.

Females are highly vulnerable to the effects of methamphetamine, and understanding the mechanisms of this is critical to addressing methamphetamine use as a public health issue. Hormones may play a role in methamphetamine sensitivity; thus, the fluctuation of various endogenous peptides during the postpartum experience is of interest. This honors thesis project explored the relation between anxiety-like behavior, as measured by activity in an open field, and conditioned place preference to methamphetamine in female versus male rats. The behavior of postpartum as well as virgin female rats was compared to that of male rats. There was not a significant difference between males and females in conditioned place preference to methamphetamine, yet females showed higher locomotor activity in response to the drug as well as increased anxiety-like behavior in open field testing as compared to males. Further study is vital to comprehending the complex mechanisms of sex differences in methamphetamine addiction.

Description
The relationship of attachment style to both the selection and efficacy of emotion management strategies in adult dyadic contexts is not well elucidated. In non-romantic contexts, the interplay between emotion management and individual attachment style may provide a better understanding of how affect can be mitigated in daily life. The present study investigated these interactions by studying 56 pairs of college age women who were close friends. Participants were asked to have a conversation about a current source of concern/distress to one partner, while seated in the laboratory. After the conversation, participants were asked to report their subjective experience of several emotions during the conversation, such as ‘sadness,’ ‘joy,’ and ‘fear.’ Participants were also asked to complete a questionnaire assessing adult attachment style, specifically attachment anxiety and avoidance. Behavior during the conversation was coded for co-rumination and co-cognitive reappraisal by the “listener.” Listener attachment insecurity showed a trending association with increased use of co-detached reappraisal, for both avoidance (p=0.14) and anxiety (p=0.14). Listener attachment insecurity also predicted lower use of co-rumination, for both anxiety (p=0.10) and avoidance (p=0.02). Speaker attachment insecurity moderated the relationship between co-detached reappraisal and speaker emotion. Greater co-detached reappraisal predicted higher reports of non-fear negative and positive emotions, but only for high-avoidance speakers. Greater co-detached reappraisal also predicted greater non-fear negative emotions among speakers high, but not low, on attachment anxiety. Greater listener use of co-positive reappraisal was associated with higher reports of speaker fear; this effect was not moderated by speaker attachment style. These findings are discussed in relation to theoretical conceptions of attachment style, and in terms of the impact of context on emotion.

Description
Popular culture tends to downplay strong female characters to favor a plethora of male figures that children look up to as heroes. This creates a gender imbalance in exposure to inspirational characters that children can look up to as role models. For our team's creative project, we chose to write and illustrate a children's book mainly targeted at young girls, ages eight to twelve that focuses on the stories of selected female figures of Norse mythology. The five stories in our collection focus on the figures Frigg, Skadi, Elli, Idunn, and Freya and are inspired by the mythology contained in the Prose Edda by Snorri Sturluson and selected medieval texts on the Germanic Lombard tribe. Through our book, Women of Norse Myth: For Little Goddesses, we wanted to introduce children to Norse mythology, a branch of myth that is often overshadowed by more popular mythologies such as Roman and Greek. Additionally, our goal was to bring light to the female figures within Norse myth that are generally given less attention than their male counterparts. Keeping in mind these goals, the stories were adapted from the original myths in a manner that would be suitable for a young audience as well as our aim for female empowerment. The final manuscript contains an introduction to Norse cosmology, introductions to the figures, a glossary of Norse terms used, and the illustrated stories themselves. Together with our combined talents, interests, and goals, Women of Norse Myth: For Little Goddesses was completed, and we hope that someday it can be published and serve as a fun and inspiring storybook for children to read and learn from.

Description
Social Networking Sites (SNSs), such as Facebook and Twitter, have continued to gain popularity worldwide. Previous research has shown differences in online behaviors at the cultural level, namely between predominantly independent societies, such as the United States, and predominantly interdependent societies, such as China and Japan. In the current study I sought to test whether self-construal was correlated with different ways of using SNSs and whether there might be SES differences within the US that were analogous to previously observed cross-cultural differences in SNS use. Higher levels of interdependence were linked with using SNSs to keep in touch with family and friends, and providing social support to others. Interdependence was also correlated with Facebook addiction scale scores, using SNSs in inappropriate situations, and overall SNS use. Implications for assessing risk for Internet addiction, as well as understanding cultural variations in prevalence of Internet addiction are discussed.

Abstract
Diagnosing psychogenic non-epileptic seizures (PNES) requires admission to an epilepsy monitoring unit, which is a lengthy and expensive process. Despite the cost of and time commitment to this inpatient evaluation, a definitive diagnosis at the end isn’t always guaranteed. Therefore, predictor variables such as demographic information and psychological testing scores can help improve the accuracy of diagnosing PNES or epilepsy at the end of a patient’s EMU admission. Locke et al. have demonstrated that the SOM scale and SOM-C subscale on the Personality Assessment Inventory (PAI) are the best indicators for predicting PNES diagnosis, with an optimal cut score of T≥70 on both of these scales. The aim of the current study was to determine whether evaluating male and female performance separately on these relevant PAI scales improves the accuracy of diagnosing PNES. The results support the hypothesis, such that male optimal cut scores on the SOM and SOM C scales are T=80 and T=75, respectively, and female optimal cut scores on the SOM and SOM C scales are T=71 and T=72, respectively. Utilizing the results of this study can help clinicians diagnose patients with PNES or epilepsy at the end of EMU evaluation with more certainty.

Description
The transition from high school to college is marked by many changes, one of the most significant being the increased accessibility of alcohol, putting college students at high risk for alcohol-related consequences. It is imperative to identify factors that can protect young adults against these risks during this critical period. Although peers become increasingly influential in college, extant literature has shown that parents still have an impact on their children's behavior during this time. While parents spend less time with their children after college matriculation, they may indirectly protect against risky drinking behaviors by instilling certain values into their children before they make this transition. Using data from a large sample of students during their senior year of high school and their freshman year of college, the current study sought to examine interactive effects of parental communication and parental knowledge and caring on drinking behavior, and the extent to which internalization of personal drinking values mediate these effects. The primary study hypotheses were tested using path analysis conducted in Mplus 7.0. Full information maximum likelihood (FIML) estimation was utilized to estimate missing data and bootstrapping was used to address non-normality in the data. Results showed that, for those whose parents were high in knowledge and caring, higher levels of communication were associated with lower risk for alcohol use and problems at wave 3 through less permissive drinking values at wave 1. This finding has important implications for prevention approaches designed to reduce risk for heavy drinking and related problems during the transition to college.

Description
Often learning new skills, such as how to throw a basketball or how to play the piano, are better accomplished practicing with another than from self-practice. Why? We propose that during joint action, partners learn to adjust their behavior to each other. For example, when dancing with a partner, we must adjust the timing, the force, and the spatial locations of movements to those of the partner. We call these adjustments a joint body schema (JBS). That is, the locations of our own effectors and our own movements are adapted by interaction with the partner. Furthermore, we propose that after a JBS is established, learning new motor skills can be enhanced by the learner's attunement to the specifics of the partner's actions. We test this proposal by having partners engage in a motor task requiring cooperation (to develop the JBS). Then we determined whether a) the JBS enhances the coordination on an unrelated task, and b) whether the JBS enhances the learning of a new motor skill. In fact, participants who established a JBS showed stronger coordination with a partner and better motor learning from the partner than did control participants. Several applications of this finding are discussed.

Description
The relationship between parent and child is one that has been studied intensively for years. Much of the previous research in this field has quantified the parent-child relationship through self-report measures, with a subsample coding behavior from videotape and averaging individual scores across the entire parent-child interaction. Using a dynamic systems approach, we attempted to gain a deeper understanding of the parent-child relationship by quantifying the relationship in terms of dyadic patterns using the software Gridware. We then used these dyadic patterns to predict internalizing and externalizing behaviors in eight-year-old twin children. Dyadic relationship patterns predicted externalizing behaviors such as aggression and conduct disorder (i.e., frequency and stability within negative attractor states, and infrequency and low stability in positive attractor states), but not internalizing behaviors. Findings provide a method for capturing variance in parent-child interactions that is important for children's externalizing behaviors. Future studies should utilize these patterns in understanding risk and resilience family processes for children's mental health and well being.
