We introduce a new convolution operator L-a(lambda) (b, c; beta). Several SUBORDINATION and superordination results involving this operator are proved. 

In the present paper, we introduce and investigate a new result connected to subclasses of normalized and univalent functions in the open unit disk. Some majorization results and geometric properties such as radii of starlikeness, convexity, pre-Schwarzian norm and coefficient estimates are obtained.

The object of this paper is to investigate some inclusion relationships and a number of other useful properties among certain subclasses of analytic and p-valent functions, which are defined here by certain integral operator.

With numerous variables mediating the way learners interact with teacher corrective feedback (TCF), one may not comment on its efficacy before such intervening variables are adequately addressed and learners’,attendance to TCF is ensured. Among those variables, motivation is one of the most prominent ones largely affecting the degree to which students benefit from TCF. Draft-Specific Scoring (DSS), a scoring system giving learners’,a reason to notice TCF by rewarding them for the revisions they make through a flexible system of scoring, was implemented to investigate if TCF could help learners improve their use of subordinate clauses. To do so, two groups of students studying English Language Literature at the University of Tehran, consisting of 55 participants who were randomly assigned as treatment and control groups, were studied. The results of the gain analysis indicated an improvement for both groups over time in the total number and accuracy of the SUBORDINATION clauses used,however, the treatment group significantly outperformed the control group. While the two groups did not differ in their use of noun clauses, the DSS group was found to outperform the non-DSS group regarding the adverb and adjective clauses. This indicates that motivation to attend to teacher feedback is of great importance if TCF is to be effective.

In this paper, the authors investigate a new subclass of meromorphic functions associated with q-Analogue of Liu-Srivastava operator and differential SUBORDINATION. Some properties in the form of coefficient inequality, Integral representation, Radii of starlikeness and convexity, and partial sum concept are introduced.

In the present paper, we introduce a new subclass of normalized analytic and univalent functions in the open unit disk associated with Sigmoid function. Coefficient estimates, convolution conditions, convexity and some other geometric properties for functions in this class are investigated. Also, SUBORDINATION and inclusion results are obtained.
