A study assessing the effects of synchronous and asynchronous computer-mediated communication on subsequent face-to-face discussions was conducted. Participants were asked to read a short article about internet censorship. Then they were randomly assigned to one of three groups: a synchronous (internet chat) group, an asynchronous (internet discussion board) group and a control group. Both the ...

The Community of Inquiry (COI) theoretical framework suggests that successful higher education experiences are supported by the presence and interaction of cognitive, social and teaching elements. Since the COI model has been widely used for examining quality of asynchronous computer-mediated communication (CMC) educational interactions, its applicability to synchronous CMC interactions is rela...

Byzantine agreement is typically considered with respect to either a fully synchronous network or a fully asynchronous one. In the synchronous case, t + 1 communication rounds are necessary for deterministic protocols whereas all known probabilistic protocols require an expected large number of rounds. In this paper we examine the question of how many initial synchronous rounds are required for...

Computer Mediated Communication (CMC) researchers often cite a dichotomy that distinguishes synchronous and asynchronous media. We examine the historical development of this bifurcated classification, as well as present evidence about the manner CMC media is actually used in the field. We speculate about the evolutionary and biological basis for this behavior. We suggest that synchronicity shou...

This paper presents a low-communication overhead and high-performance data parallelism implementation of the Everglades Landscape Fire Model (ELFM) in a network of workstations (NOWs). ELFM is parallelized under Message Passing Interface (MPI). Checkpointing and rollback technologies are used to handle the spread of re which is a dynamic and irregular component of the model. A parallel applicat...

In this paper we show that every real-time system speciied in a certain subset of Duration Calculus 24] can be decomposed into an untimed system communicating with suitable timers. Both asynchronous and synchronous communication are considered.

Secure multi-party computation (MPC) allows several mutually distrustful parties to securely compute a joint function of their inputs and exists in two main variants: In synchronous MPC parties are connected by a synchronous network with a global clock, and protocols proceed in rounds with strong delivery guarantees, whereas asynchronous MPC protocols can be deployed even in networks that deliv...
