Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The baroreceptor reflex is a multi-input, multi-output physiological control system that regulates short-term blood pressure by modulating nerve activity between the brainstem and the heart. The computational model by Park et al. (2020) is the most recent iteration in our exploration of the system. However, the contributions of”the little brain of the heart”, the intrinsic cardiac nervous system (ICN), to local control of the heart and to the integration of sensory information is unknown and has been overlooked in previous models. We have incorporated a high-fidelity representation of the ICN into a model of the baroreceptor reflex based on anatomical, …

The Scientific Study Of Positive Psychology, Religion/Spirituality, And Physical Health, Kevin S. Masters, Julia K. Boehm, Jennifer M. Boylan, Kaitlyn M. Vagnini, Christina L. Rush

Psychology Faculty Books and Book Chapters

Humans have long been interested in relations among religion/spirituality (R/S), positive psychological constructs, and physical health. Furthermore, many religions attempt to influence behavior through health-related prescriptions about food choices, sexual activity, substance use, and resting. Similarly, positive psychological constructs have been discussed in light of their presumed benefits on both mental and physical health (Ryff & Singer, 1998). However, R/S and positive psychological constructs have only recently become objects of scientific investigation of their associations with physical health.

The effect of the pyrolysis temperature between 400–900 °C and of the CaO/digestate mass ratio between 0–0.5 was discussed, as well. The CHEMCAD application allowed to investigate …


A Framework For Creating And Using Teaching Philosophy Statements To Guide Reflective And Inclusive Instruction, Steven D. Taff Jan 2023

A Framework For Creating And Using Teaching Philosophy Statements To Guide Reflective And Inclusive Instruction, Steven D. Taff

Journal of Occupational Therapy Education

A teaching philosophy statement (TPS) is a brief, deeply personal narrative that gives insight into an educator’s perspective on the teaching enterprise. A TPS is typically comprised of a reflection on the educator’s values and beliefs, a description of what happens during the learning process, and statements about how teachers and learners ideally interact. Use of a TPS clarifies the bridge between theory/philosophy and practice which strengthens education as an interactive phenomenon and in so doing evokes an ethical purpose for the teaching-learning dynamic. This article describes the theoretical underpinnings of, and process for, an innovative framework occupational therapy educators …


Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne Jan 2023

Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne

UNF Graduate Theses and Dissertations

BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with …
