I examine how consumers' purchase' decisions and intentions of purchases are affected by uncertainty about future deals (temporary price cuts or sales) for a product and how these results affect retailers' optimal pricing and marketing strategies. First I look at the effects of uncertainty about the timing of deals (i.e....
In this thesis we study protein folding with external force. In Part I we simulate the folding or unfolding procedure based on the two-state model. For constant-velocity experiments, the simulation results fit the experimental results. For constant-force experiments, we introduce cooperativity between domains to explain the different behavior between single...
This study examined the effects of swallow task on swallow physiology, respiratory phase relationships, and oxygen saturation in healthy adult males. This study hoped to provide a building block to clinically relevant research with individuals with compromised swallowing and respiration. Subjects included 40 healthy adult males with no history of...
Various methods for solving the partial contact of surfaces with regularly periodic profiles-- which might arise in analyses of asperity level contact, serrated surfaces or even curved structures--have previously been employed for elastic materials. A new approach based upon the summation of evenly spaced Flamant's solution is presented here to...
Northwestern University developed copper-precipitation-hardened, high-performance weathering steel (NUCu 70W Steel) that is produced by hot rolling after casting and then air-cooling. Due to simple processing the steel is fabricated at lower cost than competing high-performance steels that require quench and tempering. NUCu 70W steel can be easily welded without pre-...
The endothelial cell (EC) lining of the pulmonary vascular system forms a semipermeable barrier between blood and the interstitium and regulates various critical biochemical functions. Collectively, it represents a prototypical biomechanical system, where the complex hierarchical architecture, from the molecular scale to the cellular and tissue level, has an intimate...
Increasing evidence points to associations between light-dark exposure patterns, feeding behavior, and metabolism. This study aimed to determine the acute effects of 3 hours of morning versus evening blue-enriched light exposure compared to dim light on hunger, met-abolic function, and physiological arousal. Nineteen healthy adults completed this 4-day inpatient protocol...
Touch screen devices such as smartphones and tablets are now ubiquitous in the lives of American children. These devices permit very young children to engage interactively in an intuitive fashion with actions as simple as touching, swiping and pinching. Yet, we know little about the role these devices play in...
Background
Over-testing and overtreatment in older adults may lead to harm. Clinician decision support redirecting attention to possible harms and engaging social and reputational concerns might reduce overuse.
Methods
We performed an 18-month pragmatic cluster-randomized trial in 60 primary care practices with 371 clinicians, comparing behavioral-science-informed point-of-care clinical decision support...
