    The Power, Structure, and Practice of Gratitude in Education: A Demonstration of Epistemology and Empirical Research Working Together

    Full text link
    A growing body of philosophical, psychological, and educational research shows that gratitude has positive effects on mood, relationships, and learning. This paper explores the power of gratitude, investigates how the ontological (inward), teleological (forward), and metaphysical (upward) structure of gratitude can enhance learning, and then highlights a research study revealing teachers’ perspectives on the impact of practicing gratitude in the classroom environment. Four themes emerged from the empirical study that support the gratitude structure: two themes relate to the impact on teachers (enhanced well-being and calm amidst stress), and two themes relate to the impact on students (enhanced classroom environment and strengthened learning). Together, the epistemological framework and the empirical evidence demonstrate that using the structure and the practice of gratitude together in the context of the classroom environment bolsters educational pursuits

    Homotopy decompositions and K-theory of Bott towers

    Full text link
    We describe Bott towers as sequences of toric manifolds M^k, and identify the omniorientations which correspond to their original construction as toric varieties. We show that the suspension of M^k is homotopy equivalent to a wedge of Thom complexes, and display its complex K-theory as an algebra over the coefficient ring. We extend the results to KO-theory for several families of examples, and compute the effects of the realification homomorphism; these calculations breathe geometric life into Bahri and Bendersky's recent analysis of the Adams Spectral Sequence. By way of application we investigate stably complex structures on M^k, identifying those which arise from omniorientations and those which are almost complex. We conclude with observations on the role of Bott towers in complex cobordism theory.Comment: 26 page

    Widespread depolarization during expiration: A source of respiratory drive?

    Get PDF
    Respiration influences various pacemakers and rhythms of the body during inspiration and expiration but the underlying mechanisms are relatively unknown. Understanding this phenomenon is important, as breathing disorders, breath holding, and hyperventilation can lead to significant medical conditions. We discuss the physiological modulation of heart rhythm, blood pressure, sympathetic nerve activity, EEG, and other changes observed during inspiration and expiration. We also correlate the intracellular mitochondrial respiratory metabolic processes with real-time breathing and correlate membrane potential changes with inspiration and expiration. We propose that widespread minor hyperpolarization occurs during inspiration and widespread minor depolarization occurs during expiration. This depolarization is likely a source of respiratory drive. Further knowledge of intracellular and extracellular ionic changes associated with respiration will enhance our understanding of respiration and its role as a modulator of cellular membrane potential. This could expand treatment options for a wide range of health conditions, such as breathing disorders, stress-related disorders, and further our understanding of the Hering–Breuer reflex and respiratory sinus arrhythmia

    Walking as Do-It-Yourself Urbansim

    This article develops a series of theoretical notions arising in the context of an urban art project that took place in London in the summer of 2004 under the title “Where do you breathe?”1 As a participatory urban intervention, the project challenged the notion of authorship in public space by casting the act of walking as a transformation of urban space, and examined the potentials for a practice of photography based on interaction rather than passive representation
