the present research aimed at investigating the interaction of the classroom talk to have a better understanding of the teachers’ practice teaching which can pave the way for reflection on teaching. the study benefitted from conversation analytic perspective to qualitatively and interpretively examine the classroom discourse of the teacher-learner interaction. the classroom talk was analyzed th...

The notion of conversations, and their associated conversation protocols, as abstract representations to be used to characterise extended agent message exchanges has been discussed in the agent community for several years now. However, there is still no consensus on an appropriate formal specification for these abstractions. This paper describes a proposed formalism based on Petri Nets that is ...

The conversation model captures interactions among the components of a composite web service. A conversation is the global sequence of messages exchanged among the components. We discuss the impact of asynchronous communication on the conversation behavior. It turns out that the conversation behavior is significantly different for synchronous and asynchronous communication and demands new techn...

Online communities are creating a growing legacy of texts. These texts record conversation, knowledge exchange, and variation in topic and orientation as groups grow, mature, and decline; they represent a rich history of group interaction and an opportunity to explore the purpose and development of online communities. The problem is how to approach and make sense of the vast amount of data stor...

Problems of conventional evaluation models can be understood as an impoverished ‘conversation’ between realities (of non-linearity, indeterminate attributes, and everchanging context), and models of evaluating such realities. Meanwhile, ideas of systems thinking and complexity science – grouped here under the acronym STCS – struggle to gain currency in the big ‘E’ world of institutionalised eva...

Nursing presence, although it involves action at times, is a humanitarian quality of relating to a patient that is known to have powerful and positive implications for both nurse and patient. However, this phenomenon has not been well understood. Three theories, drawn from the work of Paul Ricoeur and Hans-Georg Gadamer, served as the boundaries for both data collection and analysis. The theori...

We investigated whether people can identify who is speaking in multiparty conversations solely on the basis of the head orientations of the participants in the conversation. Two experiments were conducted using a virtual meeting room. Participants were shown the head orientations of four virtual humans and were asked to identify the speaker. In the first experiment participants were shown stati...
