Description
Hand-coding systems of measuring facial expressions were developed to study and analyze human emotions, but they are time-intensive and thus seldom used. As technology has advanced, new computer software programs, such as Affectiva, were developed to code facial expressions automatically using artificial intelligence and machine learning. Since this technology is still new, Affectiva and its validity remain understudied, and no psychological research has been conducted to compare Affectiva computer coding and hand coding of children’s emotions. The purpose of this study was to compare hand and computer coding of children’s expressions of emotion during a videotaped parent-child interaction. The study answered the following questions: 1) Do hand and computer coding agree?; and 2) Are hand and computer coding in higher agreement for some emotions than others? The sample included 25 pairs of twins from the Arizona Twin Project. Facial expressions were coded from videotape by a trained and reliable human coder and using the software Affectiva. The results showed that hand and computer coded emotion were in agreement for positive, but not negative emotions. Changing the context of the interaction to elicit more negative emotion, and using the same indicators of each emotion in computer and hand coding are suggested to improve the comparison of computer and hand coding.

Description
Women are twice as likely as men to develop Major Depressive Disorder (MDD), and current MDD therapies are only effective for about a third of patients. Hormonal transitions, specifically those involving estradiol (E2), have been found to contribute to this increased vulnerability in women. This study aimed to investigate potential mechanisms underlying the sex differences seen in MDD vulnerability, specifically the role of E2. The brain region-specific changes induced by chronic stress differ for female rats than for male rats. Therefore, we aimed to determine the effects of sex and chronic stress on E2 expression in four brain regions: the hippocampus, medial prefrontal cortex, amygdala, and cerebellum. Sprague-Dawley rats (n = 48, 24 males, 24 females; n=12/Tx group) were subjected to daily wire mesh restraint stress (6 h/21 days), and were euthanized and dissected the day following the end of chronic restraint stress (day 22). Ultra high-pressure liquid chromatography-mass spectroscopy was used to directly measure E2 in the brain regions. Quantitative real-time PCR was used to indirectly assess E2 expression via mRNA for aromatase (ARO-L) and estrogen receptors (ERβ, ERɑ, and GPR30), as well as expression of inflammatory cytokines (IL-1β and TNF-ɑ). Our findings suggest that chronic stress may lead to changes in local estradiol expression in the brain that are both sex-dependent and brain region-specific, while the data are preliminary given the small sample size. We found that expression of ARO-L mRNA, a measure of local E2 production, tended to increase in the HIPP, but decrease in the mPFC following chronic stress, and in the mPFC this pattern was only observed in males. Local estradiol production in the brain seems to act as a potential compensatory mechanism in the hippocampus, but as a protective mechanism in the mPFC, which is highly sensitive to chronic stress.

Description
Previous research demonstrated the overall efficacy of an embodied language intervention (EMBRACE) that taught pre-school children how to simulate (imagine) language in a heard narrative. However, EMBRACE was not effective for every child. To try to explain this variable response to the intervention, the video recordings made during the four-day intervention sessions were assessed and emotion was coded. Each session was emotion-coded for child emotions and for child-researcher emotions. The child specific emotions were 1) engagement in the task, this included level of participation in the activity, 2) motivation/attention to persist and complete the task, as well as stay focused, and 3) positive affect throughout the session. The child-researcher specific emotions were 1) engagement with each other, this involved how the child interacted with the researcher and under what context, and 2) researcher’s positive affect, this incorporated how enthusiastic and encouraging the researcher was throughout the session. It was hypothesized that effectiveness of the intervention would be directly correlated with the degree that the child displayed positive emotions during the intervention. Thus, the analysis of these emotions should highlight differences between the control and EMBRACE group and help to explain variability in effectiveness of the intervention. The results did indicate that children in the EMBRACE group generally had a significantly higher positive affect compared to the control group, but these results did not influence the ability for the child to effectively recall or moderate the EEG variables in the post-test. The results also showed that children who interacted with the researcher more tended to be in the EMBRACE group, whereas children who did not interact with the researcher more frequently were in the control group, showing that the EMBRACE intervention ended up being a more collaborative task.

Description
Pediatric chronic pain is surprisingly common and impactful, prospectively predicting poorer mental and physical health outcomes. Internalizing symptoms represents one such outcome. It is the most common cluster of symptoms in children, it is related to poorer child functioning, and it has been linked to future functioning/psychopathology. The psychosocial mechanisms through which child pain may impact internalizing have yet to be fully elaborated, but withdrawal from social engagement with peers has been proposed as one possible mechanism. Additionally, sibling relationships may play a role in enhancing or diminishing a child’s social engagement while they are in pain. The current study aimed to examine whether child social engagement at age 8 mediates the relation between child chronic pain at age 8 and internalizing symptoms at age 9. Further, the study tested whether sibling warmth and sibling conflict act as moderators between child chronic pain and child social engagement. The physical and emotional health, quality of sibling relations, and extracurricular social engagement of 491 twin children from 247 families were assessed at age 8 and age 9 via surveys completed by the children’s primary caregivers. Findings showed that child pain at age 8 did not predict lower levels of social engagement, and social engagement did not predict child internalizing at age 9. Sibling warmth, but not conflict, significantly moderated the pain—social engagement relation. Together, these findings indicate that the relation between chronic pain and internalizing functions differently in children than in adults through a variety of cognitive, environmental, and social factors. More longitudinal research in this area will help establish changes in the relation between pain and internalizing from childhood into adulthood.

Description
With opioid use disorder (OUD) being an epidemic, it is important to investigate the mechanisms as to why this is so. This study established a self-administration paradigm to model and investigate the mechanisms of polysubstance, sequential use in conjunction with the analysis of withdrawal symptomatology driven by opioid withdrawal. The independent variables were dichotomized into the control group (food/cocaine) and the experimental group (oxycodone/cocaine). We hypothesized that more cocaine would be self-administered on the first day of oxycodone withdrawal. In addition, we hypothesized that somatic signs of withdrawal would increase at 16 hours post-oxycodone self-administration. Finally, we hypothesized that cocaine intake during oxycodone withdrawal would potentiate subsequent oxycodone self-administration. Our findings revealed that animals readily discriminated between the active (food or oxycodone) and inactive levers - but will however require more animals to achieve the appropriate power. Further, the average cocaine infusions across phases exhibited significance between the oxycodone/cocaine and food/cocaine group, with the average cocaine infusions being lower in food than in oxycodone-experienced animals. This implies that the exacerbation of the sequential co-use pattern in this case yields an increase in cocaine infusions that may be driven by oxycodone withdrawal. Further, to characterize withdrawal from oxycodone self-administration, somatic signs were examined at either 0 or 16 hrs following completion of oxycodone self-administration. The oxycodone/cocaine group exhibited significantly lower body temperature at 16 hrs of oxycodone withdrawal compared to 0 hrs. No differences in somatic signs of withdrawal in the food/cocaine group was found between the two timepoints. Oxycodone withdrawal was not found to potentiate any subsequent self-administration of oxycodone. Future research is needed to uncover neurobiological underpinnings of motivated polysubstance use in order to discover novel pharmacotherapeutic treatments to decrease co-use of drugs of abuse. Overall, this study is of importance as it is the first to establish a working preclinical model of a clinically-relevant pattern of polysubstance use. By doing so, it enables an exceptional opportunity to examine co-use in a highly-controlled setting.

Description
There is a widely held assumption that a good chief executive in the business world will
be a good chief executive in the government. In the past, there have been many Chief Executives
in the government who have had either military experience, or some congressional experience.
President Ulysses S. Grant was a General, President Zachary Tayler was a Major General,
President Herbert Hoover was the Secretary of Commerce, and contributed to the Treaty of
Versailles, and therefore cannot be criticized on the basis of having no practical government
experience, as well as President Dwight D. Eisenhower, who was also a Commanding
General. On the other hand, with many well-known entrepreneurs, people tend to focus on the
achievements that those people accomplish, and thus see that as something that can be
transitioned from business to politics. However, I would argue that this is generally not the case.

Description
Sophia’s Stuffed Friends is a book written for children of divorce, aged five to eight years. The story deals with anxiety, depression, and misappropriated guilt in the form of character traits in Sophia’s stuffed animals. The story takes place in a dream world after the stuffed animals are thrown into the washer of the new family house. The washer acts as a portal to the dream world. The lessons of the story are learned through flashbacks to Sophia’s life when she personally experienced anxiety, depression, and guilt. Each character learns coping mechanisms and strategies to overcome those feelings.
Squeakie is a positive influence on the way the other characters perceive themselves. The shadow turns each character’s self-doubt and negative feelings into fuel, which he stores in a paintbrush. When he takes the fuel from the character, it fades their body color. Phan has anxiety and uses the 4-7-8 breathing technique to overcome her panic attacks. Her range of color is blue to light blue. Ovid feels guilty and exercises to take his mind off his guilty thoughts. Ovid is either red or light pink. Amelia is depressed and reframes her way of thinking to overcome her inability to fly. Visually she is green or light green. The shadow is later revealed as a misguided character who was just looking to escape the dream world and find friends.
The story is resolved by the stuffed animals joining forces with the perceived antagonist, the shadow, to operate a plane. They each use their strength of color to fuel the plane, which takes them back to the real world. When Sophia’s mom pulls the stuffed animals out of the washer, the shadow comes with them. The shadow, now a cat with rainbow patches, is instantly loved by Sophia. The story ends with the stuffed animals drying on the porch bench while Sophia plays with the shadow in the new backyard.

Description
Sexual violence is a problem that is present in communities worldwide for individuals of every gender identity and religious communities are certainly not immune, including Muslim communities. This project will explore how sexual violence manifests in Muslim communities while also discussing how sexual violence is rooted in cultural patriarchy rather than the religion of Islam itself. Islam is a religion of radical gender equality. The religious discrimination against women that has been witnessed throughout the past fourteen centuries is actually the remnant of unequal gender dynamics found in pre-Islamic patriarchal culture. Sexual violence is explicitly prohibited in Islam, as evidenced by the Qur’an and ahadith (records of the Prophet Muhammad’s life) and has no place in the global Muslim community, referred to as the Ummah.
This paper also delves into feminism in Islam and argues that Muslim women should not be forced to choose between their faith and their human rights; rather, women should be able to obtain an education and should play an essential role in the interpretation of religious texts.
The purpose of this thesis project is twofold: to examine the intersection of Islam, women, and sexual violence prevention as well as to develop and apply a sexual violence prevention curriculum that can be implemented within Muslim communities. The textual analysis of this project will include discussions regarding the primary source of the Qur’an as well as the secondary sources of ahadith and existing literature written by Muslim scholars, primarily female Muslim scholars. This will allow for an analysis of how women are portrayed in Islam as well as how Islamic texts and traditions challenge the patriarchy and rape culture in which sexual violence manifests. Using this foundational knowledge, the goals of the sexual violence prevention curriculum will be to facilitate a discussion between Muslims regarding what sexual violence looks like and what rape culture is, create support networks for survivors, discuss what to do if a friend discloses that they are a survivor or victim of sexual violence, reduce roadblocks to reporting, and analyze literature on feminism in Islam in order to support a movement for sexual violence prevention.

Description
Family influences are known predictors of adolescent health and well-being trajectories, yet little research has investigated how adolescents’ orientation to family may be associated with their physiological stress responses. Influenced by the strength-based approach to culture, this study evaluated 418 Hispanic adolescents' familism values and perceived life stress in family, school, and peer domains to investigate prospective associations with hypothalamic-pituitary-adrenal axis stress responses to the Group Public Speaking Task for Adolescents (GPST-A). Prior growth-mixture modeling on this sample revealed a five-class solution of cortisol responding to the GPST-A that was used here as the dependent variable: one class showed a more pronounced pattern of reactivity, potentially indicative of hyper-responsivity to the stress task; two classes showed evidence of a low to moderate cortisol response, potentially indicative of an adaptive physiological response to the challenge; and two classes showed patterns of non-responsivity, potentially indicative of hypo-responsivity. Results demonstrate that the role of familism is nuanced in the context of stressors, potentially offering both promotive and risk-amplifying effects for the physiological stress response system. This study offered several novel findings in the relation between cultural factors, salient stressors of adolescence, and HPA activity.

Description
There is a long, ongoing search for the best way to measure and promote creativity. In this study, participant’s self-reported interdependence with elicited members of their social life (Same-Sex Best Friend, Same-Sex Acquaintance, Sibling (or Relative), and Enemy) were collected alongside their performance on several iterations of J.P. Guilford’s Alternative Uses Task. It was predicted that higher scores obtained on the fitness interdependence scale would predict higher scores on the creativity tasks, and lower scores on the former would also predict lower scores on the latter. Ultimately, the results did not support our hypothesis that creative efficiency is predicted by an individual’s self-reported interdependence with members of their social circle. Although higher scores on the Same-Sex Best Friend Interdependence, Sibling (Relative) Interdependence, Acquaintance Interdependence, and Enemy Interdependence categories were found to significantly predict a higher number of alternative uses submitted in a creativity task, the fact that these four subcategories predicted the Total Volume score and not the Total Originality score shows that a better design, and more robust methods, must be used to investigate the relationship between interdependence and creative outcomes.
