Learners are often reported not to be motivated enough to attend to teacher feedback. Teachers also  tend  to  grade  learners’  writing  samples  when  providing  them  with  corrective  feedback though  they  know  it  may  divert  their  attention  away  from  teacher  feedback.  However,  not grading learner writings does not seem to be an option due to both learners’ demands for it and ins...

It is often wrongly assumed that the provision of teacher corrective feedback naturally entails learners' attendance to and application of it, but learners have repeatedly been reported not to pay attention to teacher feedback due to lack of motivation and the distracting effect of the grades they receive. The present study was an attempt to tackle this problem. To do so, the technique named Dr...

drafts of major primary tillage implements were measured in a clay loam soil using a tension loadcell. implements consisted of a moldboard, a disk and a chisel plow each equipped with one tillage unit. a photoelectric speed sensor was used for actual forward speed measurements. during the study, the effects of forward speed and tillage depth on draft requirements were investigated. a general re...

We will establish lower bounds in terms of the level for the number of holomorphic cusp forms of weight k > 2 whose various L-functions do not vanish at the central critical point. This work generalizes the work of W. Duke [1] which was for the case of weight 2.

Let H0 be an arbitrary self-adjoint n × n matrix and H(n) be an n × n (random) Wigner matrix. We show that t 7→ Tr exp(H(n)−itH0) is positive definite in the average. This partially answers a long-standing conjecture. On the basis of asymptotic freeness our result implies that t 7→ τ(exp(a − itb)) is positive definite whenever the noncommutative random variables a and b are in free relation, wi...
