this study considers an eoq inventory model with advance payment policy in a fuzzy situation by employing two types of fuzzy numbers that are trapezoidal and triangular. two fuzzy models are developed here. in the first model the cost parameters are fuzzified, but the demand rate is treated as crisp constant. in the second model, the demand rate is fuzzified but the cost parameters are treated ...

Tension generated by growth cones regulates both the rate and the direction of neurite growth. The most likely effectors of tension generation are actin and myosins. We are investigating the role of conventional myosin in growth cone advance. In this paper we report the localization of the two most prominent isoforms of brain myosin II in growth cones, neurites and cell bodies of rat superior c...

The last decade has seen rapid growth in the presence of computational thinking (CT) educational contexts. Those working to advance CT argue that concepts and skills associated with are e...

It is well known that a high degree of relative risk aversion induces equilibrium indeterminacy in cash−in−advance economies. I find that by endogenously adjusting the nominal money supply to output fluctuations, these equilibria can be effectively eliminated. This paper was written while I was a DFG Heisenberg Fellow. I would like to thank the Federal Reserve Bank of San Francisco for its hosp...

This article demonstrates that self-help programs are experiencing explosive growth; that psychologists are to be credited with a substantial body of research dating back to the 1970s; that this research demonstrates the potential of self-help programs; that some psychologists have failed to heed the results of studies by rushing to market with exaggerated product claims; and that the American ...

Testing the comprehension of spoken language is of primary importance. A lot of factors may affect the performance of EFL learners on listening comprehension tests, among which are the use of visual advance organizers, and types of listening passages (dialogues or monologues). As B-Ikeguchi (1997) states a few studies have been carried out on the effects of these factors on EFL learners’ listen...

T he U.S. economy continues to advance briskly, defying forecasts of more moderate growth. Beginning in March 1991, the current expansion has become the longest peacetime expansion on record and is less than a year away from becoming the longest in U.S. history. To the surprise of some observers, economic growth has been particularly robust late in the expansion. In fact, over the last three ye...
