Infant Mental Health Journal: Infancy and Early Childhood, Volume 44, Issue 2, Page 200-217, March 2023., 2023 Abstract Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment‐based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring ...

A modified Post Widder operators preserving eᴬˣ
, 2022 In the present paper, we discuss the approximation properties of modified Post-Widder operators, which preserve the test function eᴬˣ. We establish weighted approximation and a direct quantitative estimate for the modified operators.

Infant Mental Health Journal: Infancy and Early Childhood, Volume 40, Issue 5, Page 640-658, September/October 2019., 2019 ABSTRACT Latina immigrant women are vulnerable to traumatic stress and sexual health disparities. Without autonomy over their reproductive health and related decision‐making, reproductive justice is elusive. We analyzed behavioral health data from 175 Latina immigrant participants (M age = 35; range = 18–64) of the International Latino Research ...

Summability of a Tchebysheff system of functions
Journal of Function Spaces, Volume 8, Issue 1, Page 87-102, 2010., 2010 We consider a special type of Tchebysheff systems of functions {ui(⋅)}in=0 and {Vi(⋅)}in=0 defined on the intervals (0, 1] and [1,+∞), respectively, such that ui(t)=tα0∫t1t1α1∫t11t2α2…∫ti−11tiαidtidti−1…dt1 and ui(t)=tβ0∫1tt1β1∫1t1t2β2…∫1ti−1tiβidtidti−1…dt1.

On simultaneous approximation for some modified Bernstein‐type operators
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 71, Page 3951-3958, 2004., 2004 We study the simultaneous approximation for a certain variant of Bernstein‐type operators.

A note on integral modification of the Meyer‐König and Zeller operators
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 31, Page 2003-2009, 2003., 2003 Guo (1988) introduced the integral modification of Meyer‐Kö nig and Zeller operators Mˆn and studied the rate of convergence for functions of bounded variation. Gupta (1995) gave the sharp estimate for the operators Mˆn. Zeng (1998) gave the exact bound and claimed to improve the results of Guo and Gupta, but there is a major mistake in the paper of ...

Lp‐inverse theorem for modified beta operators
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 20, Page 1295-1303, 2003., 2003 We obtain a converse theorem for the linear combinations of modified beta operators whose weight function is the Baskakov operators. To prove our inverse theorem, we use the technique of linear approximating method, namely, Steklov mean.

Solution of time‐varying singular nonlinear systems by single‐term Walsh series
Mathematical Problems in Engineering, Volume 2003, Issue 3, Page 129-136, 2003., 2003 A method for finding the solution of time‐varying singular nonlinear systems by using single‐term Walsh series is proposed. The properties of single‐term Walsh series are given and are utilized to find the solution of time‐varying singular nonlinear systems.

Extension of the best approximation operator in Orlicz spaces and weak‐type inequalities
Abstract and Applied Analysis, Volume 6, Issue 2, Page 101-114, 2001., 2001 We consider an extension of the best approximation operator from an Orlicz space L φ to the space L φ′, where φ′ denotes the derivative of φ, and we prove a weak‐type inequality in this space. Further, we obtain some strong inequalities for suitable L ψ spaces.
