Timing Matters: Tackling Intractable Problems
I f you were at least five years old on 20 July 1969, then you know exactly where you were when Neil Armstrong became the first human to walk on the moon. With that act, America won the space race. Safely going to and returning from the moon was a long-term goal that required solving a myriad of related technical problems. It took concerted resolve to overcome this heretofore intractable scient...
متن کاملInterceptive timing: prior knowledge matters.
Fast interceptive actions, such as catching a ball, rely upon accurate and precise information from vision. Recent models rely on flexible combinations of visual angle and its rate of expansion of which the tau parameter is a specific case. When an object approaches an observer, however, its trajectory may introduce bias into tau-like parameters that render these computations unacceptable as th...
متن کاملGeolocation for Twitter: Timing Matters
Automated geolocation of social media messages can benefit a variety of downstream applications. However, these geolocation systems are typically evaluated without attention to how changes in time impact geolocation. Since different people, in different locations write messages at different times, these factors can significantly vary the performance of a geolocation system over time. We demonst...
متن کاملPatent pool formation: Timing matters
This paper addresses the problem of non-cooperative patent pool formation by owners of patents related to a standard. We develop a model in which competing manufacturers must license several patents to produce standard-compliant goods. Separate licensing creates a double-marginalization problem. Moreover manufacturers must sink a fixed cost to enter the product market, and thus face a hold-up p...
متن کاملBackchannels: Quantity, Type and Timing Matters
In a perception experiment, we systematically varied the quantity, type and timing of backchannels. Participants viewed stimuli of a real speaker side-by-side with an animated listener and rated how human-like they perceived the latter’s backchannel behavior. In addition, we obtained measures of appropriateness and optionality for each backchannel from key strokes. This approach allowed us to a...
