Description
The function and purpose of higher education has changed over the last decade. COVID-19 exacerbated that change, but well before Coronavirus exploded on the world stage, standard operations at most colleges and universities were in flux. In 2013, a New York Times article predicted many colleges and universities would shutter their doors or merge with another institution. A new paradigm for post-secondary education is emerging akin to what American community colleges have been doing since their inception; they work closely with industry and the community in which they are situated to ensure they teach skills students need to receive a living wage job upon graduation. Change and disruption have engendered problems at times tantamount to chaos in the higher education space. To make meaningful modifications in higher education, the chaos of change should be harnessed to devise a better system, as transformative chaos works its power to create a more cohesive model. Moreover, if change is not managed with expertise, it has the potential to run amok, leaving organizations in ruins. The purpose of this study was to examine how a nine-week workshop based in mindfulness and gentle movement affected College of Eastern Idaho staff members’ ability to manage constant change to see if it might augment their coping, competence, self-efficacy, resiliency and reframe the chaos of change to opportunity for their careers, their department, and the college. Mixed methods of inquiry were utilized; data sources included two pre- and post-intervention staff surveys, a focus group interview with four participants, participant journals they kept throughout the nine-weeks, and the researcher’s field notes from individual one-on-one check-ins with participants. This study demonstrated that staff members at College of Eastern Idaho had difficulty efficaciously performing their jobs because of the constant change and initiative fatigue. The study found that a nine-week Mindfulness from the Mat workshop positively impacted staff members coping, competence, self-efficacy, resiliency, and their attitudes about change. Moreover, the workshop had unexpected benefits of positively impacting participants personal lives, too. The discussion includes implications for future practice and research and potential explanations for the findings.

Description
Adults with autism spectrum disorder (ASD) face heightened risk of co-occurring psychiatric conditions, especially depression and anxiety disorders, which contribute to seven-fold higher suicide rates than the general population. Mindfulness-based stress reduction (MBSR) is an 8-week meditation intervention centered around training continuous redirection of attention toward present moment experience, and has been shown to improve mental health in autistic adults. However, the underlying therapeutic neural mechanisms and whether behavioral and brain changes are mindfulness-specific have yet to be elucidated. In this randomized clinical trial, I utilized functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to characterize fMRI functional activity (Study 1) and connectivity (Study 2) and EEG neurophysiological (Study 3) changes between MBSR and a social support/relaxation education (SE) active control group. Study 1 revealed an MBSR-specific increase in the midcingulate cortex fMRI blood oxygen level dependent signal which was associated with reduced depression. Study 2 identified nonspecific intervention improvements in depression, anxiety, and autistic, and MBSR-specific improvements in the mindfulness trait ‘nonjudgment toward experience’ and in the executive functioning domain of working memory. MBSR-specific decreases in insula-thalamus and frontal pole-posterior cingulate functional connectivity was associated with improvements in anxiety, mindfulness traits, and working memory abilities. Both MBSR and SE groups showed decreased amygdala-sensorimotor and frontal pole-insula connectivity which correlated with reduced depression. Study 3 consisted of an EEG spectral power analysis at high-frequency brainwaves associated with default mode network (DMN) activity. Results showed MBSR-specific and nonspecific decreases in beta- and gamma-band power, with effects being generally more robust in the MBSR group; additionally, MBSR-specific decreases in posterior gamma correlated with anxiolytic effects. Collectively, these studies suggest: 1) social support is sufficient for improvements in depression, anxiety, and autistic traits; 2) MBSR provides additional benefits related to mindfulness traits and working memory; and 3) distinct and shared neural mechanisms of mindfulness training in adults with ASD, implicating the salience and default mode networks and high-frequency neurophysiology. Findings bear relevance to the development of personalized medicine approaches for psychiatric co-morbidity in ASD, provide putative targets for neurostimulation research, and warrant replication and extension using advanced multimodal imaging approaches.

Description
Research on self-regulatory variables like mindfulness and effortful control proposes strong links with physical and mental health outcomes across the lifespan, from childhood and adolescence to adulthood and old age. One pathway by which self-regulation may confer health benefits is through individual differences in reports of and emotional responses to daily negative and positive events. Mindfulness is broadly defined as non-reactivity to inner experiences, while effortful control is broadly defined as attentional and behavioral regulation. Mindfulness and effortful control have both been conceptualized to exert their beneficial effects on development through their influence on exposure/engagement and emotional reactivity/responsiveness to both negative and positive events, yet few empirical studies have tested this claim using daily-diary designs, a research methodology that permits for examining this process. With a sample of community-dwelling adults (n=191), this thesis examined whether dispositional mindfulness (i.e., non-reactivity of inner experience) and effortful control (i.e., attention and behavioral regulation) modulate reports of and affective reactivity/responsiveness to daily negative and positive events across 30 days. Results showed that mindfulness and effortful control were each associated with reduced exposure to daily stressors but not positive events. They also showed that mindfulness and effortful control, respectively, predicted smaller decreases in negative affect and smaller increases in positive affect on days that positive events occurred. Overall, these findings offer insight into how these self-regulatory factors operate in the context of middle-aged adults’ everyday life.
