Prevost(1984).The interaction of generalized thermoelastic waves with anisotropic media was studied by Banerjee and Pao(1974),and Sharma et al.(1986;1989)Guided waves were considered by several researchers.Nayfeh and Nemat(1971),Sinha(1975)studied thermoelastic Rayleigh waves.Harinath et al.(1976)studied Stonely-type waves.Mondal et al.(1973),Massalas(1986)considered the propagation of generalized thermoelastic waves in thin plates.Erby and Sunhubi(1986)studied the problem of longitudinal waves in a circular rod.In contrast,little work has been conducted on thermoelastic waves in layered/or composite media.Sve(1971)used the classical theory of thermoelasticity treat obliquely travelling waves in a bilaminated isotropic medium.His analysis was conducted by using potential functions.The results were given in the form of an exact dispersion relation resulting from the vanishing of a selfthorder determinant.Example2:4.1 Analysis on example2A methodological approach the

Neile Osmans work with Australian immigrants(Osman,1959).As a movement,however,it did not really survive the attack made on it by Wilkins in the early 70s(e.g.Wilkins,1973).Wilkins main objection therefore is that the situational approach is superficial.Widdowson,for instance,observes that The danger of such analysis is that.Recent work by Ventola(1983;1984),Martin(1985),Coupland(1983)and others opts for.Current trends are towards reconstructing accounts that include.Speech community has been an evolving concept.and the variety of.criteria has been discussed by Hudson(1980),Saville-Troike(1982)and especially by Braithwaite(1984).At the outset,a speech community was seen as being composed of those who share similar linguistic rules(Bloomfield,1933).Later,Labov will emphasize shared norms.(Labov,1966:7).Finally,there are those such as Hymes who argue for multiple criteria.4.1 Example 1The situational ahowever,it did not
