Abstract We reconsider the decomposition of comparative statics effect a factor price increase on (unconditional) demand into substitution and size (or level) effect. While for own go same negative direction, cross cannot be signed unambiguously, in general. But two cases regularity, homotheticity complementarity, is negative. furthermore show by example that both special effects are still ambi...
It is verified that, at small Zeeman energies, the charged excitations in the vicinity of 1/3 filled Landau level are skyrmions of composite fermions, analogous to the skyrmions of electrons near filling factor unity. These are found to be relevant, however, only at very low magnetic fields. PACS numbers: 73.40.Hm Typeset using REVTEX 0Accepted for publication in Solid State Communications (199...
This study sought to compare the metacognitive knowledge profile of weak and strong students in problem solving. For achieving this purpose, one hundred students of the second educational District of Tehran were chosen by cluster sampling. They responded individually to the questions of "the Metacognitive Questionnaire Interview" and in the next step their performance in the pendulum problem so...
