Subordination and Superordination Results for a Class of Analytic Multivalent Functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We derive subordination and superordination results for a family of normalized analytic functions in the open unit disk defined by integral operators. We apply this to obtain sandwich results and generalizations of some known results.

Development and Integration of Community Advisory Boards to Inform Research on the Impact of Structural Racism on Racial/Ethnic Disparities in End-Stage Kidney Disease. [PDF]

open access: yesHealth Expect
ABSTRACT Introduction Community Advisory Boards (CABs) represent a critical methodological approach to center research on the experiences of patients and families and minimise power inequities between ‘researcher’ and ‘subject’. This approach can be especially important to inform work related to structural racism and racial and ethnic disparities in ...
