Methods To Study Activity Dependent Protein Synthesis In Autism Spectrum Disorder, Megan Webb, Karin F K Ejendal, Tamara L. Kinzer-Ursem

Discovery Undergraduate Interdisciplinary Research Internship

It is estimated by the World Health Organization that 1 in 100 children have autism spectrum disorder (ASD), a condition characterized by neurological differences that may impact a person’s learning or behavior. Clinically, ASD symptoms are alleviated with behavioral or pharmacological therapies, however, not all patients respond to these interventions. Deep brain stimulation (DBS) is a promising treatment of Parkinson’s disease that could also be effective in treating ASD. SynGAP1 is a protein involved in neuronal action that is crucial for regulating synaptic plasticity. Mutations in the SYNGAP1 gene causing haploinsufficiency can result in the manifestation of ASD symptoms. This …

Emergent Bilinguals’ Participation In Multilingual Engineering Learning Ecologies, Alberto Esquinca, Maria Teresa De La Piedra, Lidia Herrera-Rocha

Journal of Pre-College Engineering Education Research (J-PEER)

Students classified as English language learners (ELLs), many of whom are also Hispanic/Latine´/x, are at times excluded from opportunities to engage in engineering design experiences due to the emphasis on learning English. In dual language bilingual education, however, language policies that allow for the use and development of more than one language afford opportunities for ELLs that are not available in monolingual environments. We draw on a multilingual learning ecology theoretical framework to analyze data gathered from a two-year ethnographic study. During approximately 200 hours of field work, we gathered multiple forms of data through ethnographic methods, to include field …

Journal of Human Performance in Extreme Environments

With a renewed impetus and appetite for human space exploration, both government-funded agencies and private companies are focusing on longer and farther crewed missions into the solar system. Such space missions rely on highly interdependent teams living and working together in isolated, confined, and extreme (ICE) environments. Understanding the behavioral patterns of teams in ICE environments is, thus, paramount for the future success of such missions. Due to the complexity of studying ICE teams, several researchers have called for methodological innovations to advance knowledge in this area. In the current research, a proof-of-concept methodological approach is introduced that provides a …

Influence Of Core Temperature Changes During Whole-Body Warming And Cooling On Cutaneous Vascular Reactivity, Lydia Tsoutsoubi, Leonidas G. Ioannou, Stephen S. Cheung, Andreas D. Flouris

Journal of Human Performance in Extreme Environments

Objective: Endothelial function, the ability of cells of the vascular endothelial wall to secrete compounds, is linked with metabolic and cardiovascular disease risks. One of the most well-known noninvasive tests used to assess skin vascular reactivity as a measure of endothelial function is the reactive hyperemic response test (RHRT). However, there is lack of consensus regarding the impact of thermoregulation on endothelial (dys)function and the results from the RHRT. Thus, the aim of the present study was to investigate the impact of core temperature on cutaneous vascular reactivity, as assessed via the finger RHRT. Approach: Following a 15-minute baseline period, …

To assess engagement, we measure link clicks to further resources and webinar …

The Role Of Region And Religious Tradition In Predicting Individuals’ Expressions Of Faith In The Workplace, Jacqui Frost, Christopher P. Scheitle, Elaine Howard Ecklund, Denise Daniels

Purdue University Libraries Open Access Publishing Fund

While many variables might influence an individual’s willingness to express their faith in the workplace, the role of regional context has not been fully considered. The different geographical regions in the U.S. consist of unique demographics and cultures that could shape an individual’s expression of faith at work. Moreover, these regional effects might be moderated by an individual’s specific religious tradition. Using data from a survey of U.S. adults featuring oversamples of Jewish and Muslim individuals, we utilize two unique measures of religious expression—displaying/wearing religious items at work and talking about religion at work—to assess the roles of region and …
