Undergraduate Study Abroad Perceptions Post Pandemic – A Study on BGSU Students

The purpose of this project is to answer the following research questions: 1). What benefits of doing a study abroad are most impactful in a BGSU undergraduate student’s decision on whether to study abroad? 2). What are the most significant barriers for students of taking action to study abroad at BGSU? I will be generating primary data from interviewing undergraduate students and analyzing the data using statistical tools. I will use this data to figure out which groups of benefits and which groups of barriers are most impactful for different demographic groups so I can provide insightful recommendations to policy makers in the education abroad office. Using BGSU as my research context, I have developed a questionnaire to administer to 100 undergraduate students to obtain the data and used Hofstede\u27s cultural dimensions theory to tie the data with theory-backed support. I also researched study abroad benefits and barriers across other American universities to help me develop an adequate questionnaire. Also, since there were not many Covid-related barriers that have been fully studied, I am contributing my own background to develop new research in terms of how impactful Covid-19 was to BGSU undergraduate students\u27 perception of barriers related to this specific virus

The Relationships Between Nurse Attributes, Site Characteristics, And Labor Support Attitudes And Behaviors Among Intrapartum Nurses

Most American women deliver their babies in the hospital; an opportunity for nurses to make a positive impact. However, nursing labor support has been associated with fewer positive outcomes than support performed by lay providers, doulas, or midwives. Positive outcomes associated with continuous labor support include decreased cesarean deliveries, and use of medication or epidurals for pain. It was unclear why the outcomes were not as great when nurses provided labor support. The purpose of this study was to describe the relationships between nurse attributes, organizational characteristics, and labor support attitudes, behaviors, and perception of barriers among intrapartum nurses. Conceptual frameworks for the study included the Theory of Reasoned Action and The Professional Labor Support Model. An exploratory, descriptive, mixed methods study was conducted with a purposive sample of labor and delivery nurses who work in three different hospital settings (rural, suburban, urban) in one region of a midwestern state. Participants completed the Labor Support Questionnaire (LSQ) in an online format. Participants who completed the survey were asked to participate in follow-up interviews. Responses to questions on the LSQ were statistically evaluated to identify differences between sites and significant correlations. Sixty nurses (57%) responded to the online survey and 11 participated in follow-up interviews. There were no significant differences in LSQ findings between participants in the three settings. Personal birth experiences were correlated with attitudes and intended behaviors. Data triangulation revealed that LSQ and interview findings were consistent; women-centered care, preparing women, using presence (or nonpresence), and taking charge when needed, were aspects of labor support that were highly valued by the nurses studied. However, labor support differed when women used epidurals for analgesia; use of nonpresence increased. Barriers to labor support included staffing, documentation, physicians, high-technology interventions, doulas, and birth plans. Enablers of labor support included valuing collaboration with managers, doulas, providers, education and experience. Participants placed great importance on women-centered labor support but may not be aware of personal factors that impact care they provide. Interventions that are based only on women\u27s perceived needs, and do not reflect evidence-based practice may not promote labor progress and improved outcomes

Optimization of Simultaneous Facial EMG and fMRI

The scientific study of emotion began in the 19th century with Duchenne’s study of the “universal and immutable” language of facial expressions. In The Mechanism of Human Physiognomy, he manipulates human facial expressions by electrically stimulating facial muscles. Facial electromyography (EMG) is a modern technique that is reminiscent of Duchenne’s work; it allows researchers to measure facial muscle activity through surface recording electrodes, providing a real-time measure of natural emotional reactions. Although facial EMG is a reliable measure of emotional behavior, it fails to provide any information about brain activity responsible for emotional processes. Functional magnetic resonance imaging (fMRI) can fill this gap, but facial EMG and fMRI are rarely used simultaneously because the electromagnetic field produced by MRI complicates traditional EMG recording. The present study aims to address this challenge and optimize a protocol for simultaneous EMG and fMRI recording. We plan to use a BIOPAC EMG100C-MRI amplifier to record facial EMG while participants are scanned in a 3 Tesla MRI. To reduce electromagnetic noise interference with the EMG signal, we will determine optimal scanning parameters and arrangement of electrodes and cables. Remaining noise will be removed by a series of analog and digital filters. For example, a comb band stop filter targeting the electromagnetic frequencies of the MRI could be applied during preprocessing. This novel, multi-modal approach is a logical next step for the field of emotion research. Furthermore, this protocol could be extended to other areas of research and clinical applications
