Ligita, Titan; Harvey, Nichole; Wicking, Kristin; Francis, Karen; Nurjannah, Intansari – Health Education, 2021
Purpose: This paper aims to explicate one of the major findings of a research study seeking to understand how Indonesian people with diabetes learn about their disease. The one key finding discussed in this paper is how families influence the learning and self-management processes adopted by Indonesian people with diabetes.…

Schacher, Samuel; Hu, Jiang-Yuan – Learning & Memory, 2014
An important cellular mechanism contributing to the strength and duration of memories is activity-dependent alterations in the strength of synaptic connections within the neural circuit encoding the memory. Reversal of the memory is typically correlated with a reversal of the cellular changes to levels expressed prior to the stimulation. Thus, for…

Martinková, Patricia; Drabinová, Adéla; Liaw, Yuan-Ling; Sanders, Elizabeth A.; McFarland, Jenny L.; Price, Rebecca M. – CBE - Life Sciences Education, 2017
We provide a tutorial on differential item functioning (DIF) analysis, an analytic method useful for identifying potentially biased items in assessments. After explaining a number of methodological approaches, we test for gender bias in two scenarios that demonstrate why DIF analysis is crucial for developing assessments, particularly because…

Lai, Lufanna C. H.; Cummins, Robert A. – Social Indicators Research, 2013
Two studies investigate subjective wellbeing (SWB) homeostasis. The first investigates the contribution of job satisfaction (JS) and partner satisfaction (PS) to the homeostatic defense of SWB. The extant model of homeostasis does not include either variable. The second study investigates the relationship between Homeostatically Protected Mood…

Snow, Wanda M.; Cadonic, Chris; Cortes-Perez, Claudia; Chowdhury, Subir K. Roy; Djordjevic, Jelena; Thomson, Ella; Bernstein, Michael J.; Suh, Miyoung; Fernyhough, Paul; Albensi, Benedict C. – Learning & Memory, 2018
The brain has a high demand for energy, of which creatine (Cr) is an important regulator. Studies document neurocognitive benefits of oral Cr in mammals, yet little is known regarding their physiological basis. This study investigated the effects of Cr supplementation (3%, w/w) on hippocampal function in male C57BL/6 mice, including spatial…

Sundman, Eva; Olofsson, Peder S. – Advances in Physiology Education, 2014
Neural reflexes support homeostasis by modulating the function of organ systems. Recent advances in neuroscience and immunology have revealed that neural reflexes also regulate the immune system. Activation of the vagus nerve modulates leukocyte cytokine production and alleviates experimental shock and autoimmune disease, and recent data have…

Cooper, Robert A. – American Biology Teacher, 2015
This paper presents an activity that engages students in model-based reasoning, requiring them to predict the behavior of the trp and lac operons under different environmental conditions. Students are presented six scenarios for the "trp" operon and five for the "lac" operon. In most of the scenarios, specific mutations have…

Qun, Dominic Koh Jing; Ling, Tan Aik – Teaching Science, 2019
According to the World Economic Forum (2016), "more than one third (36%) of all jobs across all industries" (p.21) need problem-solving as a key skill. Trilling and Fadel (2009) noted the shift from industrial to knowledge-based economies, requiring students not only to possess content knowledge but also have skills that enable them to…

Semsar, Katharine; Brownell, Sara; Couch, Brian A.; Crowe, Alison J.; Smith, Michelle K.; Summers, Mindi M.; Wright, Christian D.; Knight, Jennifer K. – Advances in Physiology Education, 2019
We describe the development of a new, freely available, online, programmatic-level assessment tool, Measuring Achievement and Progress in Science in Physiology, or Phys-MAPS (http://cperl.lassp.cornell.edu/bio-maps). Aligned with the conceptual frameworks of Core Principles of Physiology, and Vision and Change Core Concepts, Phys-MAPS can be used…

Tripto, Jaklin; Ben-Zvi Assaraf, Orit; Snapir, Zohar; Amit, Miriam – International Journal of Science Education, 2016
This study examined the reflection interview as a tool for assessing and facilitating the use of "systems language" amongst 11th grade students who have recently completed their first year of high school biology. Eighty-three students composed two concept maps in the 10th grade--one at the beginning of the school year and one at its end.…

Snapir, Zohar; Eberbach, Catherine; Ben-Zvi-Assaraf, Orit; Hmelo-Silver, Cindy; Tripto, Jaklin – International Journal of Science Education, 2017
Science education today has become increasingly focused on research into complex natural, social and technological systems. In this study, we examined the development of high-school biology students' systems understanding of the human body, in a three-year longitudinal study. The development of the students' system understanding was evaluated…

Ziegler, Aaron; Van Swearingen Jessie; Jakicic, John M.; Abbott, Katherine Verdolini – Journal of Speech, Language, and Hearing Research, 2019
Purpose: This study investigated whether metabolic respiratory requirements (treadmill workload) affected glottal valving in phonation, based on aerodynamic measures, when a sound pressure level (vocal SPL) is dictated as a target goal. Consistent with a theory of action, we hypothesized that adjustments in glottal valving as measured by laryngeal…

Choi, Annette; Wang, Mengqi; Hrizo, Stacy; Buckley, Martin S. – Biochemistry and Molecular Biology Education, 2018
Exposure of organisms to high temperatures and various chemical and physical stressors can cause protein misfolding and aggregation. In turn, this can disrupt the functions of proteins, threatening both development and homeostasis. To overcome this, cells can initiate the highly conserved heat shock (HS) stress response pathway. In eukaryotes,…

Painter, Julia E.; Temple, Brandie S.; Woods, Laura A.; Cwiak, Carrie; Haddad, Lisa B.; Mulligan, Mark J.; DiClemente, Ralph J. – Health Education & Behavior, 2018
Licensure of an HIV vaccine could reduce or eliminate HIV among vulnerable populations. However, vaccine effectiveness could be undermined by risk compensation (RC), defined by an increase in risky behavior due to a belief that the vaccine will confer protection. Interest in an HIV vaccine for reasons indicative of RC may serve as an indicator of…

Mason, Kevin; Evans, Brian – Science Teacher, 2017
The "plasma membrane," which controls what comes in and goes out of a cell, is integral to maintaining homeostasis. Cell transport of small molecules across the cell membrane happens in several different ways. Some small, nonpolar molecules cross the plasma membrane along the concentration gradient directly through the "phospholipid…
