Lakatos and Hersh on Mathematical Proof
مفهوم اثبات در چند دهۀ اخیر مناقشهآمیز شده است. به طوری که افراد نظریه‌های مختلفی دربارۀ چیستی اثبات ارائه دادهاند. لاکاتوش و هرش از جملۀ این افراد هستند. نظریه‌های این دو فیلسوف شباهتها و اختلافات قابل توجهی دارند. به نظر می‌‌رسد که با مقایسه و بررسی نقادانۀ این دو نظریه فهم بهتری از مفهوم اثبات ریاضیاتی به دست خواهد آمد. دو وجه شباهت مهم بین این دو نظریه عبارتند از: دوگانه‌انگاری در اثبات ...
متن کاملA New Proof of FDR Control Based on Forward Filtration
For multiple testing problems, Benjamini and Hochberg (1995) proposed the false discovery rate (FDR) as an alternative to the family-wise error rate (FWER). Since then, researchers have provided many proofs to control the FDR under different assumptions. Storey et al. (2004) showed that the rejection threshold of a BH step-up procedure is a stopping time with respect to the reverse filtration g...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولPoly[μ6-(naphthalene-2,6-dicarboxylato)-bis(aqualithium)]
The title compound, [Li2(C12H6O4)(H2O)2] n , crystallizes with one half of the molecular entities in the asymmetric unit. The second half is gererated by inversion symmetry. The crystal structure has a layered arrangement built from distorted edge-sharing LiO3(OH)2 tetra-hedra parallel to (100), with naphthalenedi-carboxyl-ate bridging the LiO3(OH)2 layers along the [100] direction. Hydrogen bo...
متن کاملPoly[μ6-pyridine-2,4-dicarboxylato-barium]
In the title complex, [Ba(C(7)H(3)NO(4))](n), the coordination geometry around the Ba(II) ion can be described as a distorted bicapped trigonal-prismatic BaNO(7) arrangement. The pyridine-2,4-dicarb-oxy-lic acid ligands exhibit a new coordination mode. Adjacent metal centers are linked by the O atoms of the pyridine-2,4-dicarb-oxy-lic acid ligands, and then form a three-dimensional supra-molecu...
