Design for the Frail Old: Environmental and Perceptual Influences on Corridor Walking Behaviors of Assisted Living Residents

Regular walking has several physical and psychological benefits for frail older people. However, many residents in long-term care facilities are too sedentary to achieve these benefits. Indoor walking appears to be a feasible way to promote active living among these residents and yet, there is little research that has been done in this regard. The researcher conducted two studies in Central Texas to explore how corridor design features influenced indoor walking behaviors among assisted living residents. In the first study, the researcher carried out six focus groups with 50 assisted living residents, discussing how they perceived the indoor corridor as "walkable." Residents reported that a walkable corridor should be safe, comfortable, and having beautiful/interesting things to see. In the second study, the researcher further examined the relationship between the built environment and walking behaviors among 326 residents from 18 facilities in a major city of Texas. The results indicated that 'perceived looped corridor' and 'number of stories' were significantly associated with residents' frequencies of indoor recreational walking. In addition, the availability and quality of sitting space around mailbox areas influenced the number of "walking to mailbox" trips. This research provides empirical evidence to develop activity-friendly facility design guidelines, and to create environmental interventions to facilitate active lifestyles among long-term care residents

Asymptotic estimate on the distance energy of lattices

Since the well-known breakthrough of L. Guth and N. Katz on the Erdos distinct distances problem in the plane, mainstream of interest is aroused by their method and the Elekes-Sharir framework. In short words, they study the second moment in the framework. One may wonder if higher moments would be more efficient. In this paper, we show that any higher moment fails the expectation. In addition, we show that the second moment gives optimal estimate in higher dimensions.Comment: We show that the higher moments in Guth-Katz framework of Erdos distinct distances do not help, and some mor
