Sedentary Behavior and Public Health: Integrating the Evidence and Identifying Potential Solutions

Abstract: In developed and developing countries, social, economic, and environmental transitions have led to physical inactivity and large amounts of time spent sitting. Research is now unraveling the adverse public health consequences of too much sitting. We describe improvements in device-based measurement that are providing new insights into sedentary behavior and health. We consider the implications of research linking evidence from epidemiology and behavioral science with mechanistic insights into the underlying biology of sitting time. Such evidence has led to new sedentary behavior guidelines and initiatives. We highlight ways that this emerging knowledge base can inform public health strategy: First, we consider epidemiologic and experimental evidence on the health consequences of sedentary behavior; second, we describe solutions-focused research from initiatives in workplaces and schools. To inform a broad public health strategy, researchers need to pursue evidence-informed collaborations with occupational health, education, and other sectors.

Globalization and science education: The implications of science in the new economy

Abstract: Science has seen considerable change in recent decades with the emergence of a new economic and sociopolitical contract between science, the nation, state, and private commercial interests. Generally regarded as having been precipitated by globalization, these changes in the sciences are beginning to be documented by a range of commentators. Clearly, science's changing forms hold profound implications for the development of science education. As there is little science education scholarship exploring the implications sciences' altering forms, this paper attempts to investigate the relationship at more depth. Detailing this relationship is important because it can help formulate new questions, and methods for their investigation, relevant to the work of science education in the newly global world. © 2008 Wiley Periodicals, Inc.

Future thinking improves prospective memory performance and plan enactment in older adults

Abstract: Efficient intention formation might improve prospective memory by reducing the need for resource-demanding strategic processes during the delayed performance interval. The present study set out to test this assumption and provides the first empirical assessment of whether imagining a future action improves prospective memory performance equivalently at different stages of the adult lifespan. Thus, younger (n = 40) and older (n = 40) adults were asked to complete the Dresden Breakfast Task, which required them to prepare breakfast in accordance with a set of rules and time restrictions. All participants began by generating a plan for later enactment; however, after making this plan, half of the participants were required to imagine themselves completing the task in the future (future thinking condition), while the other half received standard instructions (control condition). As expected, overall younger adults outperformed older adults. Moreover, both older and younger adults benefited equally from future thinking instructions, as reflected in a higher proportion of prospective memory responses and more accurate plan execution. Thus, for both younger and older adults, imagining the specific visual-spatial context in which an intention will later be executed may serve as an easy-to-implement strategy that enhances prospective memory function in everyday life.
