Combined associations of sitting time and physical activity with obesity in young adults

Background:
We investigated associations of total sedentary behavior (SB) and objectively-measured and self-reported physical activity (PA) with obesity.

Methods:
Data from 1662 adults (26–36 years) included daily steps, self-reported PA, sitting, and waist circumference. SB and PA were dichotomized at the median, then 2 variables created (SB/self-reported PA; SB/objectively-measured PA) each with 4 categories: low SB/high PA (reference group), high SB/high PA, low SB/low PA, high SB/low PA.

Results:
Overall, high SB/low PA was associated with 95 –168% increased obesity odds. Associations were stronger and more consistent for steps than self-reported PA for men (OR 2.68, 95% CI 1.36–5.32 and OR 1.95, 95% CI 1.01–3.79, respectively) and women (OR 2.66, 95% CI 1.58–4.49 and OR 2.00, 95% CI 1.21–3.31, respectively). Among men, obesity was higher when daily steps were low, irrespective of sitting (low SB/low steps OR 2.07, 95% CI 1.03– 4.17; high SB/low steps OR 2.68, 95% CI 1.36–5.32).

Conclusions:
High sitting and low activity increased obesity odds among adults. Irrespective of sitting, men with low step counts had increased odds of obesity. The findings highlight the importance of engaging in physical activity and limiting sitting.

Friedrich Hayek and Michael Polanyi in correspondence

Friedrich Hayek and Michael Polanyi corresponded with each other for the best part ofthirty years. They had shared interests that included science, social science, economics,epistemology, history of ideas and political philosophy. Studying their  correspondenceand related writings, this article shows that Hayek and Polanyi were committedLiberals but with different understandings of liberty, the forces that endanger liberty,and the policies required to rescue it.

David and Michael discussed their creative inspirations, and how this original and contemporary work came about.

Management and Michael Polanyi's thought

Purpose – The purpose of this paper is to understand the role of management ideas as a resource for developing a new understanding of science and society.
Design/methodology/approach – Three important articles of Polanyi are studied in detail.
Findings – That writings of Graicunas, Foch and Liddell Hart definitely influenced the development of Polanyi’s thinking and writings of Gulick, Mooney among other management/organization theorists also likely contributed to Polanyi’s thought.
Research limitations/implications – The study opens a new seam for Polanyi intellectual – historical scholarship.
Practical implications – The article sheds light on facets of scientific life, including how scientists themselves participate in the overall management of science.
Social implications – This discussion of Polanyi deepens the appreciation of Liberal society’s functioning.
Originality/value – No other Polanyi scholar has dug deeply into the history of management, considering its intellectual value to Polanyi.
