The history of education in many developing nations is a template of ineffectual and expensive instruction. Despite nearly half a century of higher education in the Pacific, up to 50% of the teachers in many countries such as the Federated States of Micronesia and the Republic of the Marshall Islands still have no more than a high school education. Similar trends are found in Asia and Africa. P...
A new layout of the U-shaped automated terminal is more convenient to connect between and railway. In this study, a sort cluster scheduling method for multiple equipment yard railway proposed. The innovation points are as follows: (1) Considering that rail gantry crane (RGC), intelligent guided vehicle (IGV), double cantilever (DCRC) usually work in groups, they grouped cluster-scheduled. (2) h...
We present an algorithm selection benchmark based on optimal search algorithms for solving the container pre-marshalling problem (CPMP), an NP-hard problem from the field of container terminal optimization. Novel features are introduced and then systematically expanded through the recently proposed approach of latent feature analysis. The CPMP benchmark is interesting, as it involves a homogene...
A capability to determine the availability of nitrogen in organic amendments is necessary to ensure that such materials will provide sufficient nitrogen to the growing crop and cause minimal environmental degradation. Greenhouse bioassays were used to evaluate N availability of organic by-products, including several employed in the field study of this research. Tall fescue was grown in greenhou...
OBJECTIVE We investigated the effectiveness of a theoretically motivated intervention at reducing procedural errors in train yard operations, where making these errors could be costly or life-threatening. BACKGROUND A widespread and persistent memory error that people commit on a daily basis is the postcompletion error (PCE), that is, forgetting to complete the final step of a procedural task...
142 words) Firms face an environment changing at an increasingly rapid pace. Market opportunities in particular can arise and disappear in a short time. Unfortunately, the speed with which organizations can adapt their strategies and competencies to meet these opportunities remains limited. We argue that firms can address these individual limitations by cooperating with others for access to mar...
and in the meetings of boards of education, nor what is taking shape in the back of the superintendent's head. Even were they afforded the utmost opportunity and gifted with unusual perception, it is not likely that without convenient summaries and condensed statements they could form any idea of the public school system as a whole. If the school report is at once the evidence and test of the s...
There is a long liberal political tradition of marshalling arguments aimed at convincing Christians that distinctively Christian reasons for issuing coercive laws are not sufficient to justify those laws. In the first part of this paper I argue that the two most popular of these arguments, attributable to Locke, will not reliably convince committed biblical Christians, nor, probably, should the...
received the volume under review. He has found his introduction to this book a very pleasant experience. An index of differential diagnosis must be an extremely difficult book to plan and to edit. You cannot just turn to the specialist and ask him to write on his own subject; the contributors must be men who have had a wide general experience; for this reason we think that the editor of this pa...
