In this paper we present an analysis (in progress) of a dataset containing forum exchanges from three different MOOCs. The forum data is enhanced because together with the exchanges and the full text, we have a description of the design and pedagogical function of forums in these courses and a certain level of detail about the users, which includes achievement, completion, and in some instances...

Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

anti-fogging, [ 6 ] anti-icing, [ 7 ] buoyancy [ 8 ] and drag reduction. [ 9 ] By defi nition, a surface is superhydrophobic if the contact angle between a water drop and the surface at the solid/liquid/air interface is larger than 150 ° , and the contact angle hysteresis is small, i.e., drops readily slide or roll off when the surface is tilted slightly. [ 10–12 ] Here we explore the feasibili...

Railroad trespassers are persons on railroad property whose presence is prohibited or unlawful. Most trespassers are walking along or across railroad tracks. In 1997, fatalities to railroad trespassers became the leading cause of railroad-related deaths in the United States. In 1998, 513 persons were injured and 536 persons were killed while trespassing (Federal Railroad Administration, unpubli...

The paper arises from research that examined a healthcare coordination improvement initiative that was focused on increasing knowledge sharing among a network of healthcare workers involved in the care of children with complex medical needs. Part of this initiative involved a summary medical note (the SPOC) that was paper-based and carried by parents between the specialists involved in their ch...

Mobile devices can enhance learning and teaching by providing instant feedback and better diagnosis of learning problems, helping design new assessment models, enhancing learner autonomy and creating new formats of enquiry-based activities. The objective of this paper is to investigate the pedagogical impact of mobile voting tools. The authors’ research demonstrated that Student Response System...

In competitive situations, individuals need to adjust their behavioral strategy dynamically in response to their opponent's behavior. In the present study, we investigated the neural basis of how individuals adjust their strategy during a simple, competitive game of matching pennies. We used entropy as a behavioral index of randomness in decision-making, because maximizing randomness is thought...
