Spiritual Chemistry: The Theosophic Roots Of Newtonian Alchemy, Jeffery Tucker

The Thetean: A Student Journal for Scholarly Historical Writing

The popularization of mathematics in the Modern Era and the subsequent proliferation of technologies have created a cultural environment in which the meaning of 'science' is often assumed to be self-evident. Philosophically, this presumptive consensus derives many of its arguments from Popperian criteria, which seek to delineate the critical differences between 'science' and 'non-science.' These demarcations imply that 'science' is an empiric reality, discoverable in both its methods and qualities. Although Kuhnian relativism has attenuated the robustness of these assertions, the fact remains that many individuals purport to have an intuitive ability to state definitively, "This is science." Such claims …

Chinese University Students’ Growth In Critical Thinking: Accounting For School Transition And Selection Effects, Jinwen Luo, Minjeong Jeon, Hong Shen

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

Evaluating cognitive ability and skills development in higher education presents challenges because the focal outcome often serves as, or at least is reflected in, selection criteria for college admission decisions. Additionally, the baseline abilities and skills gained from earlier educational experiences impact students' further learning outcomes. To address these challenges, we propose an integrated framework for estimating students' growth that accounts for lasting transition effects and varying selection effects. Using a nationally representative longitudinal sample of Chinese university students, we found that students experienced medium-sized growth (0.67) in critical thinking skills, with a large effect size observed for evaluating the …

Association Between Psychiatric Diagnosis And Academic Major In College Students, Maryam Ali, Ambika Menon, Amani Carson, Larry Tupler

Research Day

Introduction: Prior literature has highlighted the high prevalence of psychiatric diagnoses amongst college students. We propose that developmental influences that shape the emergence of psychiatric disorders amongst individuals are reflected in early intellectual pursuits. Furthermore, we propose that collegiate institutional stressors relating to these pursuits can further the declaration of a disorder in students with a psychiatric diathesis. Methods: We acquired data anonymously from 1,133 colleges via a Web-based survey of 17,425 students who were ≤ 22 years old. We report the association between psychiatric disorder and choice of academic major in the first collegiate year to illuminate early developmental …

Detecting Stellar Rotation With The Synchrosqueezing Wavelet Transform, Cassandra Mcginley, Mariel Lares Martiz, Terry Oswalt, Derek Buzasi

Discovery Day - Daytona Beach

The main goal of Gyrochronology is to determine stellar ages by understanding how stars slow down in their rotation as they age. In order to achieve such a goal, rotation periods must be determined with high precision. Various tools are available for determining stellar rotation periods, such as the AutoCorrelation Function (ACF), Lomb Scargle periodograms, or Classical Wavelet analysis. However, each method has strengths and weaknesses when applied to determining stellar rotation rates. One weakness of Classical Wavelet analysis is the relatively low precision with which periods are determined. A new algorithm for wavelet analysis, called Synchrosqueezing Wavelet Transform (SWT), …

Newborn mammalian cardiomyocytes quickly transition from a fetal to an adult phenotype that utilizes mitochondrial oxidative phosphorylation but loses mitotic capacity. We tested whether forced reversal of adult cardiomyocytes back to a fetal glycolytic phenotype would restore proliferative capacity. We deleted Uqcrfs1 (mitochondrial Rieske iron-sulfur protein, RISP) in hearts of adult mice. As RISP protein decreased, heart mitochondrial function declined, and glucose utilization increased. Simultaneously, the hearts underwent hyperplastic remodeling during which cardiomyocyte number doubled without cellular hypertrophy. Cellular energy supply was preserved, AMPK activation was absent, and mTOR activation was evident. In ischemic hearts with RISP deletion, new cardiomyocytes …
