This chapter treats statistical methods for network evolution. It is argued that it is most fruitful to consider models where network evolution is represented as the result of many (usually non-observed) small changes occurring between the consecutively observed networks. Accordingly, the focus is on models where a continuous-time network evolution is(More)
One of the major goals of social network analysis is to discern fundamental structure(s) of networks in ways that: (i) allow us to know these structures and (ii) facilitate our understanding of network phenomena. One of the most used tools for doing this is blockmodeling, a collection of methods for partitioning networks according to well specified(More)
Power wheelchair users often use and carry multiple mobile computing devices. Many power wheelchair users have some upper body motor impairment that can make using these devices difficult. We believe that mobile device accessibility could be improved through designs that take into account users' functional abilities and take advantage of available space(More)
Interacting with touch screen-based computing devices can be difficult for individuals with mobility impairments that affect their hands, arms, neck, or head. These problems may be especially difficult for power wheelchair users, as the frame of their wheelchair may obstruct the users' range of motion and reduce their ability to reach objects in the(More)
For some individuals with executive function deficits, difficulties may be experienced when executing step-by-step procedures involving cognitive and motor skills. In this paper, we describe the design of a mobile application prototype, developed using a participatory-based approach, in order to enable individuals with executive function deficits to(More)

Wearable fitness devices have demonstrated the capacity to improve overall physical activity, which can lead to physical and mental health improvements as well as quality of life gains. Although wheelchair athletes who participate in adaptive sports are interested in using wearable fitness trackers to capture their activity, we have observed low adoption of(More)
