Detailed Review of Rogers’ Diffusion of Innovations Theory and Educational Technology-related Studies Based on Rogers’ Theory
The process of adopting new innovations has been studied for over 30 years, and one of the most popular adoption models is described by Rogers in his book, Diffusion of Innovations (Sherry & Gibson, 2002). Much research from a broad variety of disciplines has used the model as a framework. Dooley (1999) and Stuart (2000) mentioned several of these disciplines as political science, public health...
متن کاملA Note on The Rogers-Fine Identity
In this paper, we derive an interesting identity from the Rogers-Fine identity by applying the q-exponential operator method.
متن کاملOn the function of Erdős and Rogers
The well-known Ramsey number R(t, u) is the smallest integer n such that every Kt-free graph of order n contains a subset of u vertices with no K2. Erdős and Rogers considered a more general problem replacing K2 by Ks for 2 ≤ s < t. Extending the problem of determining Ramsey numbers they defined the following function fs,t(n) = min { max{|S| : S ⊆ V (H) and H[S] contains no Ks} } , where the m...
متن کاملOn the Generalized Rogers–ramanujan Continued Fraction
On page 26 in his lost notebook, Ramanujan states an asymptotic formula for the generalized Rogers–Ramanujan continued fraction. This formula is proved and made slightly more precise. A second primary goal is to prove another continued fraction representation for the Rogers–Ramanujan continued fraction conjectured by R. Blecksmith and J. Brillhart. Two further entries in the lost notebook are e...
متن کاملOn Elementary Theories of Rogers Semilattices
Describing the elementary theories of Rogers semilattices is one of the main problems of the theory of numberings. For the classical case of computable families of computably enumerable sets, V.V. V’jugin showed in [1] the existence of infinitely many families with pairwise elementarily different Rogers semilattices. Nevertheless, the study of Rogers semilattices undertaken in recent years (see...
