current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
A new family of generalized Stirling and Bell numbers is introduced by considering powers (V U)n of the noncommuting variables U, V satisfying UV = V U +hV s. The case s = 0 (and h = 1) corresponds to the conventional Stirling numbers of second kind and Bell numbers. For these generalized Stirling numbers, the recursion relation is given and explicit expressions are derived. Furthermore, they a...
The Stirling numbers of the second kind { n k } (counting the number of partitions of a set of size n into k non-empty classes) satisfy the relation
In this paper, we consider the degenerate forms of Catalan–Daehee polynomials and numbers by Volkenborn integrals obtain diverse explicit expressions formulas. Moreover, show in terms ?-Daehee numbers, Stirling first kind Bernoulli polynomials, also a relation covering second kind. addition, prove an implicit summation formula symmetric identity, derive expression for including polynomials.
Garsia and Remmel (JCT. A 41 (1986), 246-275) used rook configurations to give a combinatorial interpretation to the q-analogue of a formula of Frobenius relating the Stirling numbers of the second kind to the Eulerian polynomials. Later, Remmel and Wachs defined generalized p, q-Stirling numbers of the first and second kind in terms of rook placements. Additionally, they extended their definit...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
In this article, we derive representation formulas for a class of r-associated Stirling numbers the second kind and examine their connections with generalized Bernoulli polynomials. Herein, use Blissard umbral approach familiar Bell Links available literature on subject are also pointed out. The extension to bivariate case is discussed.
the purpose of this study is identifying effective factors which make customers shop online in iran and investigating the importance of discovered factors in online customers’ decision. in the identifying phase, to discover the factors affecting online shopping behavior of customers in iran, the derived reference model summarizing antecedents of online shopping proposed by change et al. was us...
An inductive method has been presented for nding Stirling numbers of the second kind Applications to some discrete probability distributions for nding higher order moments have been discussed
A remarkable multiple analogue of the Stirling numbers of the first and second kind was recently constructed by the author. Certain summation identities, and related properties of this family of multiple special numbers are investigated in the present paper.
