The First Principles Of Chinese Civilization: Relationalism And Pragmatism, Sai Zhang, Yongnian Zheng

Comparative Civilizations Review

This article examines the first principles of Chinese civilization, relationalism and pragmatism, through Liah Greenfeld’s (2024) definition of civilization as a distinct cultural reality. By comparing Chinese civilization with others, particularly in the context of globalization, we seek to identify its distinctive characteristics. Our overview analysis draws on interdisciplinary literature (including linguistics, philosophy, sociology, political economy, and social psychology). We argue that the complexities of Chinese civilization require a nuanced understanding of its first principles, which are codified in language and cognition. The article explores how these principles manifest in mainstream thoughts such as Confucianism and Legalism, influencing social structure …

Essays In Applied Microeconomics, Md Tahmeed Hossain

Economics Theses and Dissertations

This dissertation contributes to empirical economics research by examining three settings in which historical shocks, behavioral constraints, and localized public events affect social relations, decision quality, and public safety. The first chapter examines the persistence of historical religious conflict in contemporary Hindu–Muslim relations in India. The second chapter studies how time pressure affects decision quality in online chess. The third chapter analyzes the localized traffic-safety externalities of NFL game days.

Middle Management Diplomacy: An Examination Of Us Foreign Policy Analysis In Middle-Echelon Diplomatic Professionals, Isaac R. Silvino

Master's Theses

This study analyzes the role which managerial level U.S. military Foreign Area Officers and Foreign Service Officers play in shaping and implementing U.S. foreign policy. By analyzing the individual professional at the middle-echelons of an organizational hierarchy, we make an effort in dispelling ourselves from obscured perceptions of IR centered on character and state idealization driven narratives. Doing this may help bridge the foundational gap between academics and practitioners while shifting towards a paradigm of IR analysis focusing on human agency and decisions.

Result

Individual managerial echelon diplomats do not directly make policy, but rather play a crucial role in …

A Review Of Video Game Effects And Uses, David Corso

Caravel Undergraduate Research Journal

Video games are versatile in their form and function. Whether they’re training doctors or offsetting Alzheimer’s disease, video games can exercise both mental and physical features, train specific skills for a number of jobs, educate players about events and phenomenon in our world, research and understand natural human processes, and they can be designed for a number of other purposes. Multiple studies have demonstrated the effects of video games on physiological and cognitive levels—positive, negative, and everything in between. This paper identifies various physical and psychological effects that video games produce, and it suggests ways in which video games can …

Impostor Thoughts At Work: Examining The Relationship Between Impostor Thoughts, Employee Well-Being, And Coworker Support, Nikitha Sara Mohan

Theses, Dissertations and Culminating Projects

Most individuals experience impostor thoughts; however, limited construct clarity has hindered efforts to effectively examine their relationship with employee outcomes (Gullifor et al., 2021). To address this limitation, the present study adopts a sociocognitive perspective, conceptualizing impostor thoughts as beliefs that others overestimate one’s competence at work (Clance & Imes, 1978; Tewfik, 2022). Specifically, this research investigates workplace impostor thoughts and their associations with indicators of employee well-being, including job-related negative affect, burnout, physical symptoms, and perceived self-competence. Additionally, the study examines coworker support as a potential moderating factor in these relationships. A mixed-methods approach was employed. Quantitative data were …

Hemispheric Processing Of Words And Unfamiliar Symbol Strings, Karoline Curlo

Celebrating Scholarship and Creativity Day (2018-)

This study investigates the role of each cerebral hemisphere in processing word forms to better understand how the brain decodes letter strings. Participants completed a same-different judgment task for four-character word and symbol (Orkhon) pairs presented unilaterally. On different trials, a single character was substituted at the first, second, third, or fourth position in the string. Results showed a sameness advantage in the left hemisphere (LH) and a difference advantage in the right hemisphere (RH) - effects only observed with word stimuli. Performance was best when the substituted character occurred at the beginning or end of words and symbols, rather …

Unleashing Stress: The Effects Of Training, Bond Strength, And Stress On Pet Dog Behaviors And Health, London Maria Wolff

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Humans and dogs have formed a unique ability to communicate with each other through evolutionary and developmental mechanisms. This increased communication serves to form dynamic interspecies bonds by facilitating learning and training over the lifetime of a dog. However, it is not known what factors permit the unique capacity of dogs to form bonds with, and learn from, their human companions. Odor is a notable candidate for interspecies communication about emotional states, with studies showing that both dogs and humans use odor information to detect human emotions (Calvi et al., 2020). Possibly, this may include detection of both acute and …

The Sentience Of The Horse And The Philosophy Of Natural Horsemanship: Implications For Hrd Leadership, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

This paper advances a biologically grounded philosophy of leadership through the lens of Natural Horsemanship. It reframes leadership as an embodied, sentient process rather than a purely cognitive or behavioral construct. Drawing from neuroscience, affective biology, sociology, and human resource development (HRD), it proposes that the horse–human relationship provides a living model for relational intelligence. The horse’s exquisite attunement to human emotion— mediated through limbic regulation and bio-behavioral synchrony—reveals that influence arises not from authority but from coherence. Leadership, like horsemanship, is a reciprocal act of co-regulation in which trust, safety, and communication are revealed through physiology before language. By …

Sociolooking: A Theory Of Looking Together And Choreographing Looking Experiences, Avigail Shimshoni

Educational Studies Dissertations

Abstract

This dissertation addresses gaps in understandings of looking in research and practice by creating and defining sociolooking. Sociolooking is a theory of looking together and choreographing looking experiences. Researchers, educators, and practitioners across many fields value close looking and have offered step-by-step strategies for facilitating looking. While these strategies and related research are instrumental in understanding discrete aspects of looking and learning to look, they do not fully acknowledge or explore the underlying social and dynamic ways people engage in looking in everyday situations. This leads to the creation of one-dimensional, potentially inaccessible, or ineffective experiences. On the …

The Impact Of Emotional Factors On The Functioning Of Selected Muscles: Facial Muscles, Trapezius Muscle, Diaphragm And Therapy Suggestions For Physiotherapists. A Systematic Review, Kacper Chojowski, Wojciech Janik, Piotr Steuer, Maciej Tomik, Michał Kuszewski

Baltic Journal of Health and Physical Activity

Background: Extensive research has identified muscles that are particularly susceptible to emotional stimuli, namely the facial muscles, trapezius, and diaphragm. These muscles can respond to emotional stimuli by affecting the viscoelastic properties of muscles, especially stiffness. This study attempts to identify suggestions in evidence-based physiotherapy (EBP) for treating muscles that are particularly susceptible to emotions. Materials and methods: In order to achieve the goals, studies available in PubMed, PEDro, and Elsevier and Springer databases were analyzed. In the critical literature review, the following word combinations were selected: "muscle psychological stress," "muscle tonus stress," "trapezius stress," "diaphragm stress," "facial muscles stress." …

A Computational Approach To Graduated Centrifuge Profiles For Partial Gravity Planetary Environments, Cabell W. Jones

Mechanical & Aerospace Engineering Faculty Publications

Missions such as NASA’s Artemis and SpaceX’s Starship aspire towards creating permanent settlements beyond Earth. In order to achieve this goal, it must be considered that the gravity present on planetary surfaces such as the Moon (0.165 g) and Mars (0.378 g) may be insufficient to support human physiology for long term habitation. On near-Earth missions, issues such as muscular atrophy, neuro-ocular changes, cardiopulmonary variations, and bone mineral density loss have been observed proportional to the duration spent in microgravity. Further studies have suggested that the severity of these conditions scales linearly with decreasing gravity, meaning that astronaut health can …

Music To Move You: Comparing Effects Of Music Genre On Subjective Performance Of Football Players In A Practice Setting, Devin Deturk

PCOM Psychology Dissertations

Optimizing athletic performance has increasingly extended beyond conditioning to include psychological, health-related, and environmental interventions aimed at enhancing peak mental and physical fitness. However, advanced training mechanisms targeting these factors may not be readily available to all programs, necessitating cost-effective, accessible, and ethically sound adjuncts. Thus, music emerges as a potential solution that remains underutilized in applied sport settings but may be leveraged to address pervasive challenges such as fear of failure, burnout, and over-professionalization. The present dissertation investigated the effects of music in a practice setting, with particular emphasis on its capacity to enhance subjective performance, motivation, and positive …

Metabolic Mind: A Critical Literature Review On The Influence Of Mindset On Metabolic Health, Jordan Daniel M.A., M.S.

Selected Full Text Dissertations, 2011-

Evidence has demonstrated that psychological processes can influence metabolic functions, which are essential to overall health, as impaired energy metabolism can compromise physiological systems (Bobba-Alves N et al., 2022). Metabolic health is defined as a state of well-being characterized by optimal levels of blood glucose, lipids, cholesterol, blood pressure, and adiposity and is the absence of metabolic dysfunction, which encompasses but is not limited to cardiovascular diseases, type 2 diabetes mellitus, obesity, and metabolic syndrome. A powerful psychological construct that has demonstrated its influence on health is a mindset. Defined as core beliefs or assumptions about oneself and the world, …

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …

Daily Rhythms In Psychosocial Stress, Sleep, And Mood: A Multimethod Approach To Transdiagnostic Psychopathology Risk And Intervention, Gabriel Gilmore

Theses and Dissertations--Psychology

Rhythms are central to nearly every core physiological and psychological process and have profound influences on overall health and well-being, particularly in the context of mood disorders. This dissertation emphasizes a rhythm-centered framework for understanding transdiagnostic psychopathology, proposing that the temporal organization of psychosocial stress, sleep, and mood provides crucial information for the development and treatment of mood disorder symptomology. Current literature relies primarily on mean symptom levels, overlooking day-to-day patterns in psychosocial experiences. To address this key methodological gap, three studies are examined. Study 1 develops and validates the Psychosocial Stress Regularity Measure (PSRM), a brief single-item measure of …

Non-Destructive Hhxrf Archaeometry For Grouping Individuals Via Trace Element Analysis Of Dental Remains, Griffon G. Binkowski

Graduate Studies Theses and Dissertations 2026

Handheld X-ray fluorescence (HHXRF) spectrometry has been validated as an accurate, non-destructive method for analyzing archaeological osseous materials. This study utilizes HHXRF to address key bioarchaeological questions, including population differentiation, individuation, and the interpretation of bioaccumulated trace elements versus diagenetic impacts. Using dental enamel from the Maya site of Altun Ha, Belize (n=20) and several Roman-Christian sites in the Dakhleh Oasis in Egypt (n=6), the occlusal surface of molar crowns was assayed in air using a Bruker Tracer III- equipped with a 12 mil Al, 1 mil Ti, 6 mil Cu filter. Semi-quantitative trace element ratios (Sr/Ca, Fe/Ca, and Zn/Ca) …

Organ Chips And Translational Research: Identifying And Examining New Ethical Issues, Melanie Jeske

Center for Medical Ethics and Health Policy Staff Publications

Organ chips, also known as organ-on-a-chip devices, tissue chips, or microphysiological systems, have emerged over the last decade as a promising translational technology amidst growing concern about the translational crisis between laboratory research and patient bedside. Pointing to high rates of failure between nonhuman animal models and safety and efficacy in humans, organ chips and similar new approach methods have attracted substantial public and private investment. As human-cell-based alternatives to animal models, organ chips promise more predictive, efficient, and ethical platforms for pharmaceutical and toxicity testing. Engineered cultivation systems that enable cells to assemble into tissue-like structures (e.g. kidney, brain, …

The Impact Of Social Factors On Vagally Mediated Parasympathetic Activity, Andrew Scot Proctor

Theses and Dissertations

Loneliness and social disconnection are recognized risk factors for morbidity and mortality, yet the psychophysiological pathways remain contested. This dissertation examines how social factors relate to vagally mediated parasympathetic activity indexed by heart rate variability (HRV) and tests whether conversational interventions with a human or a large-language-model (LLM)-based companion can acutely reduce loneliness and enhance connection. Across two university sites (BYU, UCSD), N=297 participants (18-27 years) were randomized to (a) a reciprocal self-disclosure conversation with a trained human confederate, (b) a parallel, vocalized LLM chatbot conversation, or (c) a non-social, vocal reading control. Resting HRV (RMSSD, SDNN, HF-HRV) was recorded …

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. …

Investigating The Practice Of A Somatic, Mindful Christian Prayer And Breathing Practice On Public Speaking Anxiety, Robyn L. Middleton

Doctoral Dissertations and Projects

This randomized controlled trial investigated the effectiveness of a mindful Christian prayer practice (The Jesus Prayer) combined with slow diaphragmatic breathing on communication anxiety. Participants (N = 80) included university students and members of the general public aged 18-60 who experience public speaking anxiety. Measurements included self-reported speech anxiety and heart rate variability (assessed via the WellHero app). Repeated measures ANOVAs revealed that the mindful prayer practice had no significant effect on participants' self-reported speech anxiety or RMSSD heart rate variability. A statistical trend of lower Baevsky’s Stress Index (another variable WellHero provided) was observed in the intervention group. This …

Health And Weather In Unfavourable Environments: Exploring The Historical Dynamics Of Colonial Medical Meteorology In Nineteenth-Century Tropical Asia, Fiona Williamson

Research Collection College of Integrative Studies

Medical meteorology had a long precedent in medical thought across Eastern and Western traditions. This article considers the tradition of medical meteorology that was favoured by Western doctors in the nineteenth century, which was often applied within colonial contexts to the understanding of new climates and how they might impact on human health. Looking at British-held tropical and sub-tropical colonies of the Straits Settlements and Hong Kong respectively, medical meteorology was stimulated by the new pathological and atmospheric conditions that European explorers and settlers now inhabited in the name of the British Empire. They brought with them concepts of disease …

Physiological Regulation And Paths To Social Status In Chimpanzees, Megan F. Cole

Anthropology ETDs

In this dissertation, I leverage longitudinal comparative data from naturalistic chimpanzee populations to examine the evolutionary context for healthy aging and cooperative leadership. First, I use health data from semi-free-ranging chimpanzees living at African sanctuaries (2012-2023) to demonstrate that the effects of diet and exercise that promote healthy aging in humans are shared with chimpanzees. Semi-free-ranging chimpanzees exhibit a slower pace of biological aging compared to sedentary laboratory chimpanzees (Chapter 2). Sanctuary chimpanzees also have healthier inflammatory profiles, with no evidence of chronic inflammaging (Chapter 3). Second, I use hormonal and behavioral data from wild chimpanzees at Kanyawara (2005-2019) to …
