Twenty-Four-Hour Intermittent Fasting Extends Lifespan At The Expense Of Fecundity In Daphnia, Meridith L. Smith

Undergraduate Honors Theses

Dietary restriction (DR) is a well-established intervention for extending lifespan, yet the specific efficacy of intermittent fasting (IF) and its associated trade-offs remain under-explored in many Daphnia magna. This study investigated the effects of three IF intervals—2h, 24h, and 48h—on the longevity and fecundity of two clones of Daphnia. We hypothesized that longer fasting intervals would significantly extend lifespan at the cost of reproductive output, consistent with the disposable soma theory of resource allocation.
Our results demonstrate that 24h IF significantly increased longevity relative to ad libitum controls, even outperforming caloric restriction (CR) by reducing late-life mortality. In …

Investigating The Synergistic Effects Of Mental And Physical Exhaustion On Learning And Attention In Emergency First Responders: An Eye-Tracking Study, Kayla Page

Electronic Theses and Dissertations

ABSTRACT

Exhaustion is known to impair cognitive functioning and performance, yet its effects on learning during video-based instruction among first responders and military service members remain underexplored. This study examined how mental, physical, and combined exhaustion independently influence learning outcomes and visual attention in a physically active sample drawn from military, public safety, and emergency service roles. Visual attention was measured utilizing eye tracking, focusing on fixation duration (FD) and fixation rate (FR). Participants completed instructional tasks under each exhaustion condition, allowing comparison of learning and gaze behavior across fatigue states. Results indicated that mental and physical exhaustion were associated …

The Disruption Of Gastrointestinal Hormonal Control Of Digestion In Nile Tilapia By Omeprazole, Rema Abutaha

Theses and Dissertations (Comprehensive)

Stomach acidity is a critical feature of the digestive system, facilitating the breakdown of protein through the activation of the protease pepsin. Gastric acid is secreted by H⁺/K⁺ ATPase, the gastric proton pump. A previous study on Nile tilapia (Oreochromis niloticus) showed that inhibiting the production of stomach acid using the proton pump inhibitor omeprazole (omz), reduced growth that correlated with an acceleration of the rate of gastric emptying. This contrasts with omz exposure studies in mammals in which there is a delay in gastric emptying and no impact on growth. To understand the mechanism …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Long-term impacts of this Program include an improved food economy and enhanced patient disease management autonomy. This project aimed to increase the percentage of eligible adult medicine clinic patients enrolled in the Food Security Program by 25%, or 11 patients per month, based on the mean enrollment for the first four months of the Program (May to August) of nine patients. The intervention was based on bi-monthly performance reports, making the goal include enrolling …

Sympathetic-Cardiovascular Stress Reactivity In Adults With Major Depressive Disorder, Ashley Darling

Kinesiology Dissertations - Archive

Major depressive disorder (MDD) is a mood disorder characterized by persistently depressed mood and/or anhedonia that causes significant functional impairment in daily life. MDD affects nearly 15% of adults in their lifetime, and since 2019, prevalence estimates have increased up to ~30% in young adults (18-25 years old). In addition to its debilitating effects on daily functioning, epidemiological studies link MDD to ~3 times greater risk of cardiovascular disease (CVD), followed by accelerated CVD progression and mortality. Although the mechanisms contributing to MDD-CVD comorbidity are unclear, there is evidence of stress system dysfunction in adults with MDD.

Accordingly, the aim …

Effects Of Equine Interaction On Mutual Autonomic Nervous System Responses And Interoception In A Learning Program For Older Adults, Ann L. Baldwin, Lisa Walters, Barbara K. Rector, Ann C. Alden

People and Animals: The International Journal of Research and Practice

Equine-assisted learning (EAL) may improve the health of older adults, but scientific data are sparse. This study investigated whether people aged 55 and older show increased heart rate variability (HRV) during EAL and awareness of bodily sensations that are overall pleasant. Subjects (n = 24) participated in mindful grooming during which they slowed their breathing and brushed a horse while noticing sensations in their body and watching the horse’s reactions. The subject’s and horse’s HRV were recorded simultaneously before, during, and after mindful grooming. For control, the same subjects performed mindful grooming with a plush simulation horse. During exit …

The Influence Of Temperature And Body Size On Food Consumption In Prairie Lizards (Sceloporus Consobrinus), Morgan Pelley

Biological Sciences Undergraduate Honors Theses

Understanding the effect of temperature on physiological and digestive processes, such as voluntary consumption rate, is critical for assessing the impact of climate change. Food consumption is required for lizard survival and reproduction and its rate is dependent on temperature. For ectotherms, as temperatures increase, the amount of food consumed to meet the energy requirements related to survival and reproduction must also increase. Information on the amount of food voluntarily consumed may aid in determining if lizards can meet energy requirements. Such information could also aid in predicting survival of lizard populations, through construction of predictive climate change models. In …

The Role Of Spine In Causing Lameness In Horses, Raja Zabeeh Ullah Khan

International Programs

Lameness is one of the most important problems of horses. It influences all communities who keep horses. Recent studies have shown the significance of spinal muscles and vertebrae in inducing lameness in horses. The field has not been explored much and requires application of biomechanics to define the role of spine in inducing lameness in horses. This presentation highlights the importance of spine in inducing lameness in horses by relating the solution with biomechanics.

Critical Embodied Praxis For Social Justice And Peace Educators: A Story Of Personal Transformation Through Analysis Of My Jewish And Settler Identities, Cara Michelle Silverberg

Capstone Collection

In this paper, I examine definitions of and relationships between violence, oppression, peace, liberation, and embodiment in the context of critical pedagogy in order to construct a theory of critical embodied praxis for social justice and peace educators. Considering the body to be a tangible vessel through which narratives and mechanisms of violence are expressed and maintained, I explore the potential of the body to be a vessel through which liberatory narratives may be generated and shared. After constructing a theory of critical embodied praxis, I illustrate this framework in action through a personal narrative that explores the intersections …

A Hybrid Cognitive Architecture With Primal Affect And Physiology, Christopher L. Dancy

Faculty Journal Articles

Though computational cognitive architectures have been used to study several processes associated with human behavior, the study of integration of affect and emotion in these processes has been relatively sparse. Theory from affective science and affective neuroscience can be used to systematically integrate affect into cognitive architectures, particularly in areas where cognitive system behavior is known to be associated with physiological structure and behavior. I introduce a unified theory and model of human behavior that integrates physiology and primal affect with cognitive processes in a cognitive architecture. This new architecture gives a more tractable, mechanistic way to simulate affect-cognition interactions …

Can A Comprehensive Transition Plan To Barefoot Running Be The Solution To The Injury Epidemic In American Endurance Runners?, Michael A. Scarlett

CMC Senior Theses

Fossils belonging to the genus Homo, dating as far back as two million years ago, exhibit uniquely efficient features suggesting that early humans had evolved to become exceptional endurance runners. Although they did not have the cushion or stability-control features provided in our modern day running shoes, our early human ancestors experienced far less of the running-related injuries we experience today. The injury rate has been estimated as high as 90% annually for Americans training for a marathon and as high as 79% annually for all American endurance runners. There is an injury epidemic in conventionally shod populations that …

Co-Modulation Masking Release Begins In The Auditory Periphery, Kareem R. Hussein, Agudemu Borjigan, Mark Sayles

The Summer Undergraduate Research Fellowship (SURF) Symposium

Understanding speech in noisy environments can be difficult, especially for people with hearing loss. The background noise can cover up the sounds of interest. Normally, the auditory system works to alleviate this problem by tagging and then cancelling the noise. Our experiments are aimed at understanding the mechanism of this noise cancellation process. We hypothesize that non-linear signal processing in the mammalian cochlea (the most peripheral part of the auditory system) is the basis of noise cancellation. To test this hypothesis, we measured the responses of auditory-nerve fibers (ANFs) to sounds embedded in background noise with different statistical properties. ANFs …

Pathological Effects Of Repeated Concussive Tbi In Mouse Models: Periventricular Damage And Ventriculomegaly, Richard H. Wolferz Jr.

Honors Scholar Theses

Repeated concussive traumatic brain injury (rcTBI) is the most prominent form of head injury affecting the brain, with an estimated 1.7 million Americans affected each year (Kuhn 2012). Neurologists have been concerned about the danger of repeated head impacts since the 1920’s, but researchers have only begun to understand the long-term effects of rcTBI (McKee 2009). Although symptoms can be as mild as dizziness, current research suggests that multiple concussions can lead to a progressive degenerative brain disease known as chronic traumatic encephalopathy (CTE) (Luo 2008, McKee 2009, Kane 2013). Research on the brain is just beginning to scratch the …

'In' Or 'As' Space?: A Model Of Complexity, With Philosophical, Simulatory, And Empirical Ramifications, Charles H. Smith

DLPS Faculty Publications

A General Systems model based on ideas originating with the writings of Benedict de Spinoza is described, starting with its philosophical underpinnings, and proceeding on to its relation to modern systems concepts, including attempts to simulate the relationships posed, and measure real world structures. Central to the idea is the notion that spatial extension may not have a prior existence, but emerges only through an entropy maximization process in which information and energy exchange is balanced among some limited number of subsystems that in sum comprise any given functioning complex system. Related published empiricism concerning geographical/geological systems – the hypsometry …

The Relationship Between Vagal Tone, A Marker Of Parasympathetic Activity, And Pro-Social Behavior, Emily A. Goodlin

Scripps Senior Theses

Vagal tone, a measure of parasympathetic activity via the vagus nerve, is known to be associated with positive emotion because it promotes social engagement and self-soothing behavior. Heart rate variability (HRV), especially high frequency oscillation, is a direct measure of vagal tone, and has been used in previous studies to test the correlation between vagal tone and positive emotion. This study aims to determine if the two major oscillations of heart rate variability, high frequency (HF-HRV) and low frequency (LF-HRV) can predict pro-social behavior, which is classified as giving donations to charities. Baseline LF- and HF-HRV levels were recorded, and …

A Movement Tool Kit For The Divergent And Convergent Cps Guidelines: Instruction Cards And Activity Floor Mats, Adela Vangelisti

Creativity and Change Leadership Graduate Student Master's Projects

A Movement Tool Kit for the Divergent and Convergent CPS Guidelines:

Instruction Cards and Activity Floor Mats

Movement is as natural to humans as breathing is, and, yet, passivity starts early in schools. We are taught to sit still and in silence for long periods of time. By the time we reach adulthood and enter the workforce, we have almost forgotten our sense of embodiment. This lack of movement is counter-productive, not only to learning but to the development of creativity as well. For this project, I designed a tool to recapture the joy and playfulness of movement. Furthermore, the …
