Received doctrine that permeates the literature and practice of K-12 mathematics education, if implemented uncritically, will obstruct the development of skills that are critical for the study of calculus. Two false dichotomies are of principle concern : • Blind rote is always bad and leads to error, whereas thinking about what you are doing is always good and leads to success • Solving problem...

In their target article, Triesch et al. (2006) propose a simple model to account for the emergence of gaze following behaviour in infants. They justify the simplifications of the model by asserting that they are interested in the conditions that are sufficient for the development of gaze following behaviour. I think, however, that some of these simplifications are not just sufficient but are al...

This study employs a semi-parametric Cox proportional hazard model to study the relationship between survival time and bank-specific determinants of failure of commercial and agricultural banks during the recent recessionary period. Results indicate that non-performing consumer and commercial loans have seriously impaired banks‟ financial health and survival.

In this paper, we propose the use of geometric moments to the field of nonblind image deblurring. Using the developed relationship of geometric moments for original and blurred images, a mathematical formulation based on the Euler-Lagrange identity and variational techniques is proposed. It uses an iterative procedure to deblur the image in moment domain. The theoretical framework is validated ...
