Sacred Spaces: A Narrative Analysis of the Influences of Language and Literacy Experiences on the Self-Hood and Identity of High-Achieving African American Female College Freshmen
Late-adolescent African American students face unique difficulties on their journey to womanhood. As members of a double minority (i.e., African American and female) (Jean & Feagin, 1998), certain limiting stereotypes relevant to both race and gender pose challenges to these students. They must overcome these challenges in order to excel within the various and changing environments they move through on a daily basis (hooks, 1981, 1994). Within the context of social justice, this dissertation provides insight into the role that language and literacy practices play to help enable the positive and affirming development of self-hood of African American college freshmen. This research is qualitative and employs critical narrative inquiry to analyze data collected from six academically high-achieving African American female freshmen college students attending Ivy League, Historically Black Colleges, and private and state universities in the United States
The Resilience Of Black Female Leaders In Higher Education And Racial Microaggression
This study explored the experiences of Black female leaders in higher education and their encounters with racial microaggression. Additionally, the opportunity to understand the effects of racial slights within the workplace as either a mid to senior level leadership was also explored. Regardless of the multiple diversity, equity, and inclusion (DEI) trainings within higher education, Black female leaders are experiencing their share of racial inequality based on their race, gender, or both (DeCuir-Gunby et al., 2019). The unique experiences of racial microaggression encountered by Black women, aligned with the framework of both the Black feminist theory and intersectionality theory respectively. These theories were used to illustrate the daily occurrences of racial microaggression, within the workplace settings, where Black female leaders are not always seen as an equal to their White colleagues. Results of the study revealed that stereotypes can create a discomfort within the workplace, especially for a mid or senior level leader who is expected to remain professional regardless of their experiences with racial slights. The educational accomplishments of each participant, in addition to their professional years of experience, have been questioned or undermined either by their colleagues or subordinates. Participants expressed their experience of emotional distress caused by racial microaggression, along with a wage gap as part of their lived experience as they navigate the impact of microaggressions. Recommendations include dismantling racial microaggression within the workplace with more in-depth DEI training, along with promoting accountability towards colleagues who partake in racial slights within the workplace
Elevated CO2 concentration and leaf growth: a biophysical and biochemical analysis of cell expansion
Summary of Dissertation Recitals: Three Programs of Collaborative Music
Three collaborative piano recitals were performed in lieu of a written dissertation. The three recitals contained music written by a single composer whose compositional output is stylistically distinct. The particularities of each composer demand unique approaches to collaboration from the pianist, reflecting the changing role of the collaborative pianist through the 19th and 20th centuries. In Hugo Wolf’s Italienisches Liederbuch, showcased in the first recital, the counterpoint between pianist and singer bespeaks equal partnership, a co-inhabiting of the same musical spirit and voice. Wolf’s modernistic approach to the German lied stands alone, though it owes much to Schubert, whose music was the subject of the second dissertation recital. Franz Schubert’s Schwanengesang and his sonata for arpeggione and piano thrive on a deftly nuanced supportive engine created by the pianist; in this second recital, words and the beauty of sung melody are paramount. In stark relief to these two styles is the music of the third recital by Hungarian composer Béla Bartók, whose first violin sonata is a clamorous discord of adrenalized folk music clothed in a labyrinthine post-tonality. This third recital included a lecture which explored motivic chromaticism in Bartók’s first violin sonata and his “expressionist” period.AMUMusic: PerformanceUniversity of Michigan, Horace H.

An exploration of the experiences and utility of functional electrical stimulation for foot drop in people with multiple sclerosis
Purpose: Functional electrical stimulation (FES) is effective in improving walking in people with multiple sclerosis (MS) with foot drop. There is limited research exploring people’s experiences of using this device. This study aims to explore the utility, efficacy, acceptability, and impact on daily life of the device in people with MS.
Methods: An interpretative phenomenological approach was employed. Ten participants who had used FES for 12 months were interviewed. Transcripts were analysed, and emergent themes identified.
Results: Nine participants continued to use the device. Three relevant super-ordinate themes were identified; impact of functional electrical stimulation, sticking with functional electrical stimulation, and autonomy and control. Participants reported challenges using the device; however, all reported positive physical and psychological benefits. Intrinsic and external influences such as; access to professional help, the influence of others, an individual’s ability to adapt, and experiences using the device, influenced their decisions to continue with the device. A thematic model of these factors was developed.
Conclusions: This study has contributed to our understanding of people with MS experiences of using the device and will help inform prescribing decisions and support the continued, appropriate use of FES over the longer term
The Impact of Simulated Altitude on Selected Elements of Running Performance
Background: Simulating altitude at sea level is increasingly more popular among recreationally-trained athletes across the sports spectrum. The AltO2Lab is a commercially-available, handheld, rebreathing apparatus purported to simulate altitude. Currently, there is an overall dearth of evidence regarding the efficacy of the device. Purpose: The goal of this study was to add evidence supporting or challenging the effectiveness of the device to improve selected running performance-related variables and to investigate the time-course of changes should benefits be evidenced. Methods: The 37-day protocol included familiarization, baseline, and 2 follow-up visits during which time hematological (hematocrit and lactate), physiological (running economy, maximal VO2, and heart rate), and psychological (Borg RPE) variables were monitored at rest, during relative submaximal, and/or maximal treadmill exercise. Altitude training days (18 days; one hour each day) were fitted within the 37-day time-line to occur after the baseline visit but before the respective follow-up visits. Specifically, the altitude training took place in 3, 6-day blocks of device usage with exposure, monitored by oximetry, intensifying across the days and blocks. Twelve days of altitude training were completed before the first follow-up visit while the final 6 days of altitude training were completed between the first and second follow-up visit. In this manner, the follow-ups could serve to evaluate the potential effectiveness of the device and narrow the time course of changes to a specific usage duration. Results: Six, recreationally-trained athletes (Females = 4; Males = 2; Age = 22.0 ± 2.9 yrs.; Baseline VO2max 52.7 ± 6.7) enrolled in the study. One subject was removed due to noncompliance. Overall, simulated altitude at the prescribed, intensifying dosage, failed to change both hematocrit (p = 0.469) and VO2max (p = 0.184) when analyzed by repeated measures analysis of variance. Additionally, no differences were found for secondary variables including: running economy, heart rate, lactate or RPE (all p \u3e 0.05). Conclusion: Presently, the AltO2Lab failed to improve selected variables related to running performance. This finding is in contrast to previous investigations with the device but it does align with the knowledge that a stronger stimulus might be necessary to induce HIF-mediated erythropoiesis to the extent that the cascade could alter hematological and subsequently performance ability through enhanced oxygen-carrying capacity. These results are preliminary and a final cohort will complete testing before concluding results will be disseminated
Pre-Prandial Vinegar Ingestion Improves Two-Hour Glucose Control in Older, Type II Diabetics More Than Post-Prandial Walking
Background: Exercise engagement benefits diabetic patients through an insulin-like effect on muscle. Literature indicates that vinegar consumption may lower blood glucose levels. It is not currently clarified whether a relative amount of vinegar ingestion or a walking bout is more effective at controlling glucose in older, Type II diabetics during the acute phase following a meal. Purpose: The aim was to directly compare the impact of preferred-pace walking (15 min, postprandial) versus ingestion of a relative quantity of vinegar (0.3 g/kg) on two-hour glucose control. Methods: The two arms of the trial were completed in a randomized, crossover manner. Six Type II diabetic patients (Females = 5; Males = 1; Age = 70.5 ± 9.0 yrs.) enrolled and underwent baseline finger pricks to establish glucose levels. The test meal consisted of an 85 g bagel, 13 g of butter, and 237 mL of orange juice. On the respective days, the vinegar was diluted into 59 mL of orange juice and ingested before the meal or the subject completed a 15-min walk at 15 min post-meal. For both trials, glucose was checked every 30 min following the test meal. Results: One subject was removed from all present analysis due to medication-related non-compliance. For the vinegar trial, the resting heart rate was 72.0 (± 9.5) and baseline, 30-, 60-, 90-, and 120-min average blood glucose levels were: 117 (±12), 149 (±39), 172 (±49), 185 (±49), and 180 (±44) mg/dl. For the preferred walking speed phase, the resting heart rate was 75.5 (±15.6) and baseline, 30-, 60-, 90-, and 120-min average glucose levels were: 113 (±10), 147 (±53), 180 (±53), 208 (±72), and 206 (±71) mg/dl. Preferred walking speed was found to average 3.1 (± 1.5) kph and total steps averaged 1418 (±376). The between-arm comparison of glucose at 120-min trended towards significance (p = 0.081). Conclusions: Compared with a bout of walking, a relative quantity of vinegar may serve as a more suitable mechanism for older Type II diabetics to control acute spikes in glucose after a high carbohydrate meal. With an adequately-powered analysis, between-arm comparisons at multiple time-points would likely have achieved statistical significance. Nevertheless, the meaningfulness of the glucose control exhibited should not be lost due to the lack of statistical significance. Finally, the slow absolute preferred walking pace of many older adults may undermine the ability for walking to result in sufficient energy expenditure capable of subsequent glucose control
The Need for Reporting Metabolic Sampling Interval in Publication: An Example Using Maximal VO2 Values and Running Economy
Background: Knowledge of metabolic outcomes, such as maximal oxygen consumption (VO2) or running economy, has wide-ranging application. Metabolic outcomes are widely reported in literature yet the metabolic sampling interval (example: breath-by-breath, 30-sec average) utilized for collection is rarely ever stated. Purpose: The purposes of the present investigation were to probe the potential discrepancies created when analyzing running economy and VO2max raw metabolic data with four different metabolic sampling intervals. Methods: Five recreationally-active and endurance-trained subjects were included in the present analysis and four metabolic sampling intervals were analyzed: 30-sec average, 20-sec average, 8-breath, and 4-breath. Subjects engaged in 4-min running economy phases at 55 and 65% of their VO2max before entering into a maximal protocol purposed to elicit VO2max in 8-12 minutes. Utilizing the steady state and maximal VO2 data, metabolic sampling intervals were analyzed for their effect on reported VO2 values. Results: For running economy at 55%, there was no differences found (f = 0.207; df = 1.862; p = 0.799) between sampling frequencies when analyzed by repeated measures analysis of variance and corrected with Greenhouse-Geisser for a violation of sphericity. For running economy at 65%, there were also no differences found (f = 1.456; df = 3; p = 0.799) between sampling frequencies. For inspection, the relative VO2 values were: 27.2 (±3.1), 27.9 (±4.1), 28.4 (±3.6), and 28.8 (±5.1) for the 30-sec, 20-sec, 8-breath, and 4-breath average, respectively. Maximal VO2 values of 53.0 (±6.6), 55.1 (±7.2), 55.1 (±7.2), and 59.6 (±9.4) for the 30-sec, 20-sec, 8-breath, and 4-breath average, respectively, were found to be significantly different (f = 21.062; df = 1.278; p \u3c 0.001) after adjusting for a violation of sphericity (p \u3c 0.001). Bonferroni analysis indicated differences between the 30-sec average and all other averages and also the 20-sec and 8-breath averages when compared against the 4-breath average. The 4-breath average yielded the highest VO2max value. Coincidentally, the 20-sec and 8-breath averages were identical. Conclusion: In the present investigation of raw metabolic data, sampling interval was found to impact the maximal oxygen consumption (VO2max) values but not running economy values when investigating a small sample of data with four select sampling intervals. The report of maximal VO2 is rather common in the literature and knowing sample interval is vital for between-study comparison, determination of regression-related activities, or for pre-post comparison of data from the same or different labs
Multivariate brain-cognition associations in euthymic bipolar disorder
Background: People with bipolar disorder (BD) tend to show widespread
cognitive impairment compared to healthy controls. Impairments in processing
speed (PS), attention, and executive function (EF) may represent 'core'
impairments that have a role in wider cognitive dysfunction. Cognitive
impairments appear to relate to structural brain abnormalities in BD, but
whether core deficits are related to particular brain regions is unclear and
much of the research on brain-cognition associations is limited by univariate
analysis and small samples.
Methods: Euthymic BD patients (n=56) and matched healthy controls (n=26)
underwent T1-weighted MRI scans and completed neuropsychological tests of PS,
attention, and EF. We utilised public datasets to develop a normative model of
cortical thickness (n=5,977) to generate robust estimations of cortical
abnormalities in patients. Canonical correlation analysis was used to assess
multivariate brain-cognition associations in BD, controlling for age, sex, and
premorbid IQ.
Results: BD showed impairments on tests of PS, attention, and EF, and
abnormal cortical thickness in several brain regions compared to healthy
controls. Impairments in tests of PS and EF were most strongly associated with
cortical thickness in left inferior temporal, right entorhinal, and right
temporal pole areas.
Conclusion: Impairments in PS, attention, and EF can be observed in euthymic
BD and may be related to abnormal cortical thickness in temporal regions.
Future research should continue to leverage multivariate methods to examine
complex brain-cognition associations in BD. Future research may benefit from
exploring covariance between traditional brain structural morphological metrics
such as cortical thickness, cortical volume, and surface area
An Analysis of Best Practices for Sustainable Events and Venues in Columbus
Course Code: ENR 4567Experience Columbus is seeking ways to make the events and conferences industry of Columbus more sustainable. Events such as conferences, conventions, and other large gatherings are the targeted space behind our research. The City of Columbus has set a progressive goal to be carbon neutral by 2050. With that goal as our guiding principle, this report details ways in which the events industry can help reach that goal and implement sustainable practices. We analyzed three established frameworks of sustainability and used four case study examples to explore the many innovative ways event organizers can host sustainable events and conferences. We also met the Professional Convention Management Association (PCMA) to gain insight on how their team organizes sustainable events and learn more about their framework of evaluation. Using all of the research and information gathered from in depth literature reviews, we brought together many ideas and practices from the various frameworks and case studies into a synthesized list of six categories of best practices. Our six categories are energy, supply chain, waste reduction, transportation, water usage, and infrastructure. Detailed under each category are what we found to be the most effective ways to reduce the carbon footprint of events and conferences. This paper concludes with our recommendations on how to implement the various best practices described in the report as well as going into detail about the expected limitations and challenges of implementation.Experience ColumbusAcademic Major: Environment, Economy, Development, and Sustainabilit
