The effect of electrode position in electrocochleography
Clinical Otolaryngology, 1996This study assessed the effect of needle electrode position on the human cochlear summating potential (SP) obtained by transtympanic electrocochleography (ECochG). Electrocochleography was performed on 10 subjects with large central tympanic membrane perforations with good cochlear function, and in whom a needle electrode could be accurately placed in ...

The positive effect of explicit positive evidence
Instructed Second Language Acquisition, 2018The study investigates questions central to the field of second language (L2) acquisition and instruction: Does the first language (L1) influence the L2 grammar? Can wrong patterns be restructured? Is Universal Grammar accessible during L2 acquisition? And can L2 acquisition, rather than learning (in Krashen’s sense), be triggered by explicit positive ...

Position effect variegation in yeast
BioEssays, 1994AbstractClassically, position effect variegation has been studied in Drosophila and results when a euchromatic gene is placed adjacent to either centromeric heterochromatin or to a telomeric domain. In such a circumstance expression of the locus variegates, being active in some cells and silent in others. Over the last few years a comparable phenomenon

The Effects of Positive Mood on Memory
International Journal of Plant Sciences, 1999The results of four studies examining the effect of mood on the learning of brand names show that a positive mood enhances the learning of brand names in relation to a neutral mood. Respondents' clustering of the brand names they recalled suggests that a positive mood fosters relational elaboration by prompting the classification of brands on the basis

The positive inotropic effect of aconitine
Naunyn-Schmiedeberg's Archives of Pharmacology, 19831. The inotropic and electrophysiological effects of aconitine were measured in the isolated, isometrically contracting guinea-pig papillary muscle during the prearrhythmic phase of alkaloid action. 2. In muscles stimulated continually at 1 Hz, 1 mumol/l aconitine produced a positive inotropic effect that reached 38 +/- (SEM) 9% immediately before the ...

Position effect and related phenomena
Current Opinion in Genetics & Development, 1992Position-effect variegation in Drosophila, the mosaic expression of genes juxtaposed to heterochromatin, remains an enigmatic long-range phenomenon. While the chromatin-conformation model has been challenged, compelling contrary evidence is lacking.

Effects of Positioning on Ankle Edema
Journal of Orthopaedic & Sports Physical Therapy, 1986The purpose of this study was to determine the effects of positioning on ankle edema during a 20-minute treatment period. Fifty subjects were alternately assigned to one of two groups. Members of group A lay supine with their legs elevated, group B subjects sat with their legs dependent.
