Communication between individuals of a species is likely to increase the capacity to acquire skills useful for survival and propagation and thus may confer important selective advantages. Since interaction occurs between two or more individuals, the selective process is frequency dependent, and the analysis shows that communication cannot initially increase at a reasonable rate when it is limit...

Adaptive Playout is a solution in IP-based communication clients to compensate network issues using a dynamic receiver buffer. Whereas small buffers provoke loss artefacts due to delayed packets, large buffers result in high delay and loss of interactivity. Existing Voice over IP clients balance the trade-off between low delay and loss artefacts based on empirical values. Most often the degree ...

In the context of public introductions to emerging technologies, this study examined effects of priming and website interactivity on adolescents’ attitude development and information processing. In a four (priming) by three (interactivity levels) experiment, participants (N = 273) were required to search for and process web-based information about ecogenomics. Results showed that priming ecogen...

This chapter discusses one of the main features of ICT—interactivity. Drawing from many years of Web-based course design and delivery at the University of Hong Kong, it is argued that enhanced interactivity is the single most important reason why teachers should practice Web-based teaching. The notion of conversational learning community (CLC) as a kind of constructivist learning environment is...

We introduce online interactive proofs (OIP), which are a hierarchy of communication complexity models that involve both randomness and nondeterminism (thus, they belong to the Arthur–Merlin family), but are online in the sense that the basic communication flows from Alice to Bob alone. The complexity classes defined by these OIP models form a natural hierarchy based on the number of rounds of ...

BACKGROUND Hospital websites are considered as an appropriate system for exchanging information and establishing communication between patients, hospitals, and medical staff. Website character, website contact interactivity, shopping convenience, as well as care and service are the factors that the present study investigated as far as the patient relationship management is concerned. METHODS ...

Driven by the evolution of consumer-to-consumer (C2C) online marketplaces, we examine the role of communication tools (i.e., an instant messenger, internal message box and a feedback system), in facilitating dyadic online transactions in the Chinese C2C marketplace. Integrating the Chinese concept of guanxi with theories of social translucence and social presence, we introduce a structural mode...

Guided by interpersonal deception theory and the principle of interactivity, this investigation examined whether communication modalities differentially affect the extent to which group members develop trust or are vulnerable to manipulation and deceit, based on the degree of interactivity the modalities afford. According to the principle of interactivity, involvement and mutuality should incre...

This study assists Higher Education Institutions to gain a better understanding of the online communication strategies that influence students in developing a brand image of their universities. First, the concept of online communication strategies in HE was defined and supported by the literature review. Then, a conceptual framework that links brand equity of the university with its online stra...
