Sommario/riassunto

This title considers the special of random processes known as semi-Markov processes. These possess the Markov property with respect to any intrinsic Markov time such as the first exit time from an open set or a finite iteration of these times.The class of semi-Markov processes includes strong Markov processes, Lévy and Smith stepped semi-Markov processes, and some other subclasses. Extensive coverage is devoted to non-Markovian semi-Markov processes with continuous trajectories and, in particular, to semi-Markov diffusion processes. Readers looking to enrich their knowledge on Markov proce

Introduction: offers, refusals in postcolonial multilingual societies: new research directions -- Postcolonial pragmatics -- Offers, refusals and professional status -- Offers, refusals and age -- Offers, refusals and peer equality -- Postcolonial hybrid structures and social interaction -- Conclusion: on offer-refusal communicative acts: general implications for future research.

Sommario/riassunto

"This study offers a pragmatic dimension to World Englishes research. It is particularly timely because pragmatics has generally been understudied in past research on World Englishes, especially postcolonial Englishes. Apart from drawing attention to the paucity of research, the book also contributes to theory formation on the emerging theoretical framework, postcolonial pragmatics, which is then applied to data from two World (postcolonial) Englishes, Ghanaian and Cameroon Englishes. The copious examples used clearly illustrate how postcolonial societies realise various pragmatic phenomena, in this case offers and offer refusals, and how these could be fruitfully



explained using an analytical framework designed on the complex internal set ups of these societies. For research on social interaction in these societies to be representative, it has to take into account the complex history of their evolution, contact with other systems during colonialism, and the heritages thereof. This book does just that"--
