Previous interventions have successfully increased levels of stair climbing in publicaccess settings (e.g. malls). This study used robust methods to establish the magnitude of intervention effects amongst a specific target group – the overweight. Ascending stair/escalator users (N=20,807) were observed in a mall. A two-week baseline was followed by a five-week intervention in which message bann...

OBJECTIVES To examine specific behaviors used by older adults while ascending and descending stairs and to assess the relationships between confidence and stair performance. DESIGN Cross-sectional. SETTING Center for Locomotion Studies, The Pennsylvania State University. PARTICIPANTS Sixteen male (mean age=82.7, range= 77-89) and 16 female (mean age=82.2, range=77-87) community-dwelling a...

Since the discovery of pregnancy reversal by Dale) and Cushny,2) it is widely believed that progesterone plays a cardinal role for the maintenance of pregnancy in mammals by keeping the estrogen-dominated uterus quiescent and hyposensi tive to any given stimulation till term. If so, what is the mode of action of pro gesterone on the uterine muscle? Taking advantage of findings and methods used ...

OBJECTIVE Posttraumatic stress disorder (PTSD) related to childhood abuse is associated with features of affect regulation and interpersonal disturbances that substantially contribute to impairment. Existing treatments do not address these problems or the difficulties they may pose in the exploration of trauma memories, an efficacious and frequently recommended approach to resolving PTSD. The a...

In order to predict a pedestrian’s walking speed on stairs from his/her characteristics of and those of the stairs, the relationship between the walking speed of a pedestrian on stairs and his/her characteristics, and the relationship between the pedestrians’ walking speeds on stairs and the stair-gradients were investigated. It is suggested that Leg Extensor Power shows a strong correlation to...

INTRODUCTION In this study we investigate the influence of diabetic neuropathy (DN) on lower limb electromyography (EMG) and kinematics during stair negotiation. METHODS Forty-six adults (healthy and DN) performed stair ascent and descent tasks. Kinematic and EMG data were assessed unilaterally. RESULTS DN patients had lower ankle dorsiflexion while ascending and plantarflexion while descen...

OBJECTIVE The proliferation of studies using motivational signs to promote stair use continues unabated, with their oft-cited potential for increasing population-level physical activity participation. This study examined all stair use promotional signage studies since 1980, calculating pre-estimates and post-estimates of stair use. The aim of this project was to conduct a sequential meta-analys...

Using an analogue of the Robinson-Schensted-Knuth (RSK) algorithm for semi-skyline augmented fillings, due to Sarah Mason, we exhibit expansions of non-symmetric Cauchy kernels ∏ (i,j)∈η(1 − xiyj) −1, where the product is over all cell-coordinates (i, j) of the stair-type partition shape η, consisting of the cells in a NW-SE diagonal of a rectangle diagram and below it, containing the biggest s...

BACKGROUND This study tested the effectiveness of a stair use promotion strategy in visible and hidden stairwells during intervention and post intervention follow up. METHODS A quasi-experimental study design was used with a 1 week baseline, a 3 week intervention, and post intervention at 2 and 4 weeks in 4 university buildings in San Antonio, Texas with stairwells varying in visibility. Part...
