Quality incentive based congestion control for multimedia communication over IP networks

In this paper we introduce a framework for using quality as an incentive to promote proper application level congestion control. Through integrating a joint-source channel coder and feedback-based congestion control scheme, we are able to construct accurate and efficient quality incentives. The framework is applicable in all network architectures where end-to-end congestion control may be used, and is as such not specific to either best-effort or traffic class-based architectures. The concept is presented along with preliminary simulations that highlight the resulting rate control accuracy. We also discuss how to implement some well-known congestion control schemes within our framework.     

Self-Expression,Social Roles,and Faculty Members’ Attitudes towards Online Teaching

There is a widening gap between administrators’ and faculty members’ attitudes towards online education. This post-positivist grounded theory study explored features of the experiences that shaped sixteen faculty members’ attitudes towards online education. Two features are identified: (a) they strived to express subject matter of personal significance, and (b) they strived to take on various social roles. The degree to which these efforts were facilitated – or thwarted – shaped their attitudes towards online education. This analytical focus recognizes that online education changes not only how faculty members teach; it also introduces new activities that affect the meaning of teaching for faculty members.
