This paper presents an innovative longitudinal study developed during three years, using a design-based approach consisting of four phases. Taking into account the analysis of students’ behavior and opinions, teachers redesigned the peer assessment (PA) strategies used in the context of a Distance Education blended learning module, of a Doctoral Program, in order to improve the effectiveness of...

Reluctance towards implementation of precision agriculture (PA) seems to be based on lackof consideration to education, extension, and research sectors. The objective of this study isto identify educational, extensional, and research requirements in application of the PAsystem. The research population included all the experts in Qazvin province who are familiarwith PA concepts and PA’s equipmen...

Description The Function performs a parallel analysis using simulated polychoric correlation matrices. The nth-percentile of the eigenvalues distribution obtained from both the randomly generated and the real data polychoric correlation matrices is returned. A plot comparing the two types of eigenvalues (real and simulated) will help determine the number of real eigenvalues that outperform rand...

5 A plot of log log antheridial hyphae vs. log concentration of A2 reveals a linear relationship. From this it follows that I = e' , where I is reaction intensity, x, the concentration of A2 and k, a proportionality constant. The author wishes to thank Dr. Leonard J. Savage for pointing out this relationship. 6 An alternate interpretation of A2 activity might be that the water-soluble fraction ...

A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α, and catalyti...
