Physical activity, and likely the motivation for it, varies throughout the day. The aim of this investigation was to create a short assessment (CRAVE: Cravings for Rest and Volitional Energy Expenditure) to measure motivation states (wants, desires, urges) for physical activity and sedentary behaviors. Five studies were conducted to develop and evaluate the construct validity and reliability of the scale, with 1,035 participants completing the scale a total of 1,697 times. In Study 1, 402 university students completed a questionnaire inquiring (...) about the want or desire to perform behaviors “at the present moment (right now).” Items related to physical activity (e.g., “move my body”) and sedentary behaviors (e.g., “do nothing active”). An exploratory structural equation model (ESEM) revealed that 10 items should be retained, loading onto two factors (5 each for Move and Rest). In Study 2, an independent sample (n= 444) confirmed these results and found that Move and Rest desires were associated with stage-of-change for exercise behavior. In Study 3, 127 community-residing participants completed the CRAVE at 6-month intervals over two years- two times each session. Across-session interclass correlations (ICC) for Move (ICC = 0.72–0.95) and Rest (ICC = 0.69–0.88) were higher than when they were measured across 24-months (Move: ICC = 0.53; Rest: ICC = 0.49), indicating wants/desires have state-like qualities. In Study 4, a maximal treadmill test was completed by 21 university students. The CRAVE was completed immediately pre and post. Move desires decreased 26% and Rest increased 74%. Changes in Move and Rest desires were moderately associated with changes in perceived physical fatigue and energy. In Study 5, 41 university students sat quietly during a 50-min lecture. They completed the CRAVE at 3 time points. Move increased 19.6% and Rest decreased 16.7%. Small correlations were detected between move and both perceived energy and tiredness, but not calmness or tension. In conclusion, the CRAVE scale has good psychometric properties. These data also support tenets of the WANT model of motivation states for movement and rest (Stults-Kolehmainen et al., 2020a). Future studies need to explore how desires to move/rest relate to dynamic changes in physical activity and sedentarism. (shrink)

Several problems that pertain to certain arithmetically well-behaved countable subsemirings of Λ, the semiring of isols, are discussed. This is relevant to the present volume memorializing the late John Myhill, in that Myhill was an early co-developer of the theory of Λ.

I have always found it a sore trial of my faith to regard suam ipsam as = suam dominant, and can only join ipsam with matrem. This leaves suam stand alone, as = suam dominam. That use is doubtless defensible of a wife or mistress in the case of a lover; but it is hardly possible of a sparrow, to whom the lady does not ‘belong’ in that relation. That one who is not lover or husband may know suos is (...) no proof that he may know suum or suam alone. (shrink)

At all times, the book was understood not only as a means of preserving and transforming knowledge, but also as a means of knowing the world around us. At the same time, from ancient times it was a subject of knowledge. Gradually its theoretical phenomenon was formed. The book essentially is the most important form of consolidation and transfer of information in space and time. From the point of view of the theory of communication, the book serves as one of (...) the forms of existence and dissemination of semantic information, a means of organizing the work of individual consciousness into a sign system for the perception of its social consciousness. After all, the evolution of the book is inextricably linked with the history of mankind. She is the foundation on which the culture of peoples is built. It helps society to grow and improve, borrow and use all the mass of knowledge accumulated by mankind. The book is the most complete and comprehensive expression of the spiritual culture of mankind, since its origin and development are inextricably linked with it. (shrink)

Open peer commentary on the article “Making Sense and Meaning: On the Role of Communication and Culture in the Reproduction of Social Systems” by Raivo Palmaru. Upshot: The author addresses implications arising from socializing observer-dependent heuristics. Above all, Palmaru’s terminology is called into question since its conceptual deficiencies with regard to the relation between an observing system and its environments cause naturalistic fallacy. The author’s reply espouses a concise reanalysis of the complementary relations of fundamentally incomparable domains, namely the observer (...) and the social system. (shrink)
