Destination Integration: Linking Physiology, Histology, And Embryology Content In Foundational Sciences, Jennifer F. Dennis, Bradley A. Creamer

Faculty Publications

Anatomy and physiology are tightly linked disciplines that complement each other, however, in medical education delivery of this content is often siloed and divided. To address this, we created combined anatomy and physiology content for the female reproductive system, and team-taught designated histology and embryology topics integrated with the physiology content. Collectively, this created a more holistic incorporation of topics for student learning. Here we describe the format and approach for this teaching innovation.

Covid-19 Return To Sport: Collegiate Baseball Injury Prevalence Analysis, Troy B. Puga, Joshua Schafer, Grace Thiel, Laura Ramaker, Tejas Patel, Kevin Treffer

Faculty Publications

In the spring of 2020, the COVID-19 pandemic rapidly brought college baseball to a halt. Most college baseball players saw disruption of their training and development due to interruptions of their seasons. With these interruptions, it is necessary to examine the effects of the COVID-19 pandemic on collegiate baseball injury epidemiology. Data from a small-school Midwest collegiate conference was tallied for the number of collegiate conference injuries per year, and for the injuries per anatomic region. An unpaired t-test was conducted upon the overall conference mean injuries per year and on each anatomic region for the mean injuries per region …

Research Report: High Tunnel Tomato Fruit Cluster Pruning, Caterina Roman, Rebecca G. Sideman

Faculty Publications

Tomatoes are a high value crop grown worldwide. Indeterminate varieties are commonly grown in high tunnel structures throughout New England for the fresh market. Indeterminate tomato plants often suffer from a phenomenon called ‘June drop’ in which the plant’s first four to five cluster of fruit set perfectly but the subsequent two to three clusters have poor set and plant productivity drops suddenly. While cluster thinning (e.g., reducing the number of fruit allowed to mature per cluster) has been successfully shown to increase fruit size, it has generally not increased marketable yield. We hypothesized that reducing the fruit load by …

Faculty Publications

Background:

Sport injuries have been common among athletes across the globe for decades and have the potential to disrupt athletic careers, performance, and psyche. Many health professionals and organizations have undertaken injury mitigation strategies to prevent sport injuries through protective equipment, training protocols, and a host of other evidence-based practices. Many of these specialized training methods were disrupted due to protocols to mitigate the spread of COVID-19. This research examines the effects of the COVID-19 pandemic in relation to the prevalence of athletic injuries in the National Football League (NFL).

Objective:

During the COVID-19 pandemic, NFL teams and athletes across …

Reinvigorating A Technical Countering Weapons Of Mass Destruction Distance Learning Graduate Certificate Program, James C. Petrosky, Gaiven Varshney, Jeremy Slagley, Sara Shaghaghi

Faculty Publications

Current Countering Weapons of Mass Destruction (CWMD) demands can be divided broadly into policy and science. The science of chemical, biological, and radiological/nuclear weapons informs the limits of development, production, employment, operation, detection, risk characterization, human and material protection, and medical intervention. In short, the science of weapons of mass destruction (WMD) should precede and inform the development of policy. It is to this end that the Air Force Institute of Technology (AFIT) CWMD program was re-established, providing a technical educational option for practitioners to understand the science behind a very technically challenging subject.

Analysis Of The Cody Rnome Reveals Rsad As A Stress-Responsive Riboregulator Of Overflow Metabolism In Staphylococcus Aureus, Yoann Augagneur, Alyssa N. King, Noëlla Germain-Amiot, Mohamed Sassi, John W. Fitzgerald, Gyan S. Sahukhal, Mohamed O. Elasri, Brice Felden, Shaun R. Brinsmade

Faculty Publications

In Staphylococcus aureus, the transcription factor CodY modulates the expression of hundreds of genes, including most virulence factors, in response to the availability of key nutrients like GTP and branched‐chain amino acids. Despite numerous studies examining how CodY controls gene expression directly or indirectly, virtually nothing is known about the extent to which CodY exerts its effect through small regulatory RNAs (sRNAs). Herein, we report the first set of sRNAs under the control of CodY. We reveal that staphylococcal sRNA RsaD is overexpressed >20‐fold in a CodY‐deficient strain in three S. aureus clinical isolates and in S. epidermidis. …

Betting & Hierarchy In Paleontology, Leonard Finkelman

Faculty Publications

In his Rock, Bone, and Ruin: An Optimist’s Guide to the Historical Sciences, Adrian Currie argues that historical scientists should be optimistic about success in reconstructing the past on the basis of future research. This optimism follows in part from examples of success in paleontology. I argue that paleontologists’ success in these cases is underwritten by the hierarchical nature of biological information: extinct organisms have extant analogues at various levels of taxonomic, ecological, and physiological hierarchies, and paleontologists are adept at exploiting analogies within one informational hierarchy to infer information in another. On this account, fossils serve the role …

Physiological Indicators Of Pathologic Video Game Use In Adolescence, Sarah M. Coyne, W. Justin Dyer, Rebecca Densley, Nathan M. Money, Randal D. Day, James M. Harper

Faculty Publications

Purpose: Pathologic video game use (PVGU) has been associated with a host of negative psychological, physical, and social outcomes during adolescence; however, little research has examined physiological predictors of such use. The purpose of the study was to examine physiological predictors of the development of PVGU across adolescence.

Methods: The article involves a 1-year longitudinal study across midadolescence. Participants were 374 adolescents and their parents from a large metropolitan area in the Northwest United States. PVGU was assessed via questionnaire, as were a number of control variables. A number of physiological indicators including respiratory sinus arrhythmia (RSA) and galvanic skin …

Mechanistic Species Distribution Modelling As A Link Between Physiology And Conservation, Tyler G. Evans, Sarah E. Diamond, Morgan W. Kelly

Faculty Publications

© The Author 2015. Climate change conservation planning relies heavily on correlative species distribution models that estimate future areas of occupancy based on environmental conditions encountered in present-day ranges. The approach benefits from rapid assessment of vulnerability over a large number of organisms, but can have poor predictive power when transposed to novel environments and reveals little in the way of causal mechanisms that define changes in species distribution or abundance. Having conservation planning rely largely on this single approach also increases the risk of policy failure. Mechanistic models that are parameterized with physiological information are expected to be more …

Wild Bearded Capuchin Monkeys (Sapajus Libidinosus) Strategically Place Nuts In A Stable Position During Nut-Cracking, Dorothy M. Fragaszy, Qing Liu, Barth Wright, Angellica Allen, Callie Welch Brown, Elisabetta Visalberghi

Faculty Publications

Humans can use hand tools smoothly and effectively in varying circumstances; in other words, skillfully. A few other species of primates crack encased foods using hammer tools and anvils. Are they skilled? Positioning the food on the anvil so that it does not fall off when struck is a component of skilled cracking. We discovered that bearded capuchin monkeys deliberately place palm nuts in a relatively stable position on the anvil before striking them. In the first experiment, we marked the meridians of palm nuts where they stopped when rolled on a flat surface ("Stop meridian"). We videotaped monkeys as …

The Nation Before Taste: The Challenges Of American Culinary History, Andrew P. Haley

Faculty Publications

Food is material and familiar, and because it is, we are often overconfident about our ability to understand the culinary past. It is easy to believe that if we can discover the recipe for some forgotten dish, the history of the dish becomes intelligible. When it does not, it tempts those who consume culinary history to impose modern sensibilities on our predecessors. The Nation before Taste" argues that historians and museum curators must be especially vigilant when presenting the history of food. Reviewing a series of historical challenges that stemmed from studying the United States in the late nineteenth and …

Psychological Pathways Linking Social Support To Health Outcomes: A Visit With The “Ghosts” Of Research Past, Present, And Future, Wendy C. Birmingham, Bert N. Uchino, Kimberly Bowen, Mckenzie Carlisle

Faculty Publications

Contemporary models postulate the importance of psychological mechanisms linking perceived and received social support to physical health outcomes. In this review, we examine studies that directly tested the potential psychological mechanisms responsible for links between social support and health-relevant physiological processes (1980s to 2010). Inconsistent with existing theoretical models, no evidence was found that psychological mechanisms such as depression, perceived stress, and other affective processes are directly responsible for links between support and health. We discuss the importance of considering statistical/design issues, emerging conceptual perspectives, and limitations of our existing models for future research aimed at elucidating the psychological mechanisms …

Retributive Justice, Restorative Justice, And Forgiveness: An Experimental Psychophysiology Analysis, Charlotte Vanoyen-Witvliet, Everett L. Worthington, Lindsey M. Root, Amy F. Sato, Thomas E. Ludwig, Julie J. Exline

Faculty Publications

This experiment assessed the emotional self-reports and physiology of justice outcomes and forgiveness responses to a common crime, using a three Justice (retributive, restorative, no justice) × 2 Forgiveness (forgiveness, none) repeated-measures design. Participants (27 males, 29 females) imagined their residence was burglarized, followed by six counterbalanced justice–forgiveness outcomes. Imagery of justice—especially restorative—and forgiveness each reduced unforgiving motivations and negative emotion (anger, fear), and increased prosocial and positive emotion (empathy, gratitude). Imagery of granting forgiveness (versus not) was associated with less heart rate reactivity and better recovery; less negative emotion expression at the brow (corrugator EMG); and less aroused …

Please Forgive Me: Transgressors’ Emotions And Physiology During Imagery Of Seeking Forgiveness And Victim Responses, Charlotte Vanoyen-Witvliet, Thomas Ludwig, David J. Bauer

Faculty Publications

We assessed transgressors’ subjective emotions and physiological responses in a within-subjects imagery study involving 20 male and 20 female participants. Two imagery conditions focused on the transgressor’s actions: participants 1) ruminated about a real-life transgression and 2) imagined seeking forgiveness from the victim. Three imagery conditions focused on the victim’s possible responses: participants imagined their victims responding with 1) a grudge, 2) genuine forgiveness, and 3) reconciliation. Compared to ruminations about one’s transgression or an unforgiving response from the victim, imagery of forgiveness-seeking and merciful responses from victims (forgiveness and reconciliation) prompted improvements in basic emotions (e.g., sadness, anger) and …

Granting Forgiveness Or Harboring Grudges: Implications For Emotion, Physiology, And Health, Charlotte Vanoyen-Witvliet, Thomas Ludwig, Kelly L. Vander Laan

Faculty Publications

Interpersonal offenses frequently mar relationships. Theorists have argued that the responses victims adopt toward their offenders have ramifications not only for their cognition, but also for their emotion, physiology, and health. This study examined the immediate emotional and physiological effects that occurred when participants (35 females, 36 males) rehearsed hurtful memories and nursed grudges (i.e., were unforgiving) compared with when they cultivated empathic perspective taking and imagined granting forgiveness (i.e., were forgiving) toward real-life offenders. Unforgiving thoughts prompted more aversive emotion, and significantly higher corrugator (brow) electromyogram (EMG), skin conductance, heart rate, and blood pressure changes from baseline. The EMG, …
