Self-Regulating Intellectual Processes and Outcomes: A Social Cognitive Perspective

Abstract: At the dawn of the 21st century, many educational and psychological researchers are seeking to move beyond scientific understanding of human intellectual functioning based on correlations between motivational constructs and academic outcomes to a deeper understanding based on analyses of the causal interdependence of specific learning experiences, motivational beliefs, and academic outcomes. As research on strategy training has shown (Pressley, Borkowski, & Schneider, 1987), instructional efforts that lead to positive learning outcomes do not always produce sustained motivation, and conversely, instructional efforts to boost motivation of students without simultaneously improving their learning processes or competencies do not always produce sustained achievement (Schunk, 1991). Solving the reciprocity issue between learning and motivation is thus crucial to the advancement of educational practice.

s, S Policies for a Dynamic Inventory Model with Stochastic Lead Times

Abstract: This study analyzes a stochastic lead time inventory model under the assumptions that a replenishment orders do not cross in time and b the lead time distribution for a given order is independent of the number and sizes of outstanding orders. The study extends the existing literature on the finite-horizon version of the model and yields an intuitively appealing dynamic program that is nearly identical to one that would apply in a transformed model with all lead times fixed at zero. Hence, many results that have been derived for fixed lead time models generalize easily. Conditions for the optimality of myopic base-stock policies, and for the optimality of s, S policies are established for both finite and infinite planning horizons. The infinite-horizon model analysis is extended by adapting the fixed lead time results for the efficient computation of optimal and approximately optimal s, S policies.

Onset of reproduction in plants: size-versus age-dependency

Abstract: Understanding the roles of age and size in the timing of first reproduction or flowering in plants has become a goal for those investigating the evolution of life cycle patterns in general. Here I review the studies that are helping to clarify these roles, and indicate some directions for future research.
