The Need to Utilize Chaos Management Techniques in Elementary School Preparedness Assessment Program   M. H. Hassani Shalmaani, Ph.D.*   One of the most important programs in the Ministry of Education is the health and academic preparedness assessment program. It is assumed that any assessment program is so dynamic and unpredictable that makes systematic planning impossible. Thi...

We present our research on defining a correct semantics for forward chaining production systems (PS) programs. A correct semantics ensures that the execution of the program will not produce incorrect answers and execution will terminate; it also ensures that the answers are consistent. We define a class of stratified PS programs, and propose an operational semantics for these programs. We defin...

Program theory-driven evaluation science (PTDES) provides a useful framework for uncovering the mechanisms responsible for positive change resulting from participation in youth development (YD) programs. Yet it is difficult to find examples of PTDES that capture the complexity of such experiences. This article offers a much-needed example of PTDES applied to Project K, a youth development progr...

Ab initio calculations at the density functional theory (DFT) and the second-order Møller−Plessetperturbation theory levels with 6-31+G(d), 6-31G(d) basis sets for non-metal atoms and LANL2DZfor metal have been performed for the adsorption of dimethyl methylphosphonate (DMMP) on ZnOby Gaussisn 98 program. The calculated rotational constants by B3LYP/6-31G(d) are in moreagreement with the experi...

Objective: The present study examined the effect of choice theory education on the happiness and self-esteem in university students. Methods: The statistical population consisted of all students of Qom universities. The study sample consisted of 30 students (7 males and 8 females per group) with low self-esteem (0 out of 10) and happiness (14 out of 87) levels. The subjects were randomly selec...
