To test the proposition, college Ss were first asked to list the names of 15 campus friends. Then S was requested to rank them, according to preference as a study partner ("scholastic esteem"), desire to have them join a club of S's ("social esteem"), and desire to give them esteemable social or scholastic information about self. The results indicated a significant correlation between social esteem and the desire for the esteemed to have esteemable social and scholastic information. The scholastically esteemed were more a target for scholastic than social data. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

A simple, rapid, and specific high-performance liquid chromatographic (HPLC) procedure is described for the analysis of the chemical sweetener L-aspartyl-L-phenylalanine methyl ester (aspartame). Using a strong cation exchange column and pressures less than 1000 psig, an analysis can be performed in less than 15 min. The technique has been applied to a wide range of food products and formulations. No interferences were found in the samples studied. Recoveries are quantitative, and the coefficients of variation for replicate analyses are less than or equal to 2.5%.  相似文献

The clinical and histological features of oncocytic adenomatous hyperplasia, papillary adenoma, and papillary adenocarcinoma of the oral cavity are described, and the literature is reviewed. Histological features which may be of value in distinguishing between benign and malignant variants are described, and in view of the slow growth rate of most of these tumours, the importance of long-term follow-up is stressed.  相似文献

Reactions involving reactive species produced in electric discharges are frequently characterized by the emission of visible light of many different colors. Some typical afterglows and atomic flames have been photographed, and the observed colors (or spectral distributions) are discussed with regard to the reactions from which they arise. Laboratory studies of this sort are helpful for the understanding of the energy transfer processes which occur in flames, in electrical discharges, and in the upper atmosphere.  相似文献

From time to time, there is presented evidence on who did what first in psychology. In this column, I should like to submit five entries dating back from 2000 B.C. to 400 B.C. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This paper considers the scattering of very high frequency (VHF) electromagnetic waves from a random weakly corrugated surface by the perturbation method. The calculations show that the scattering has a resonant nature, i.e., only certain Fourier components of the surface shape are responsible for scattering in every given direction. Experiments carried out in a water basin confirmed the results of the calculations. The backscattered intensity is proportional to the spectral density of those Fourier components of the surface oscillation that have a resonant space period. In these experiments, resonant maxima of the reflected signal corresponding to the second-order approximation of the perturbation method were also observed. The frequency spectrum of the scattered electromagnetic field is also investigated. It is shown that the spectrum of the scattered radiation is shifted from the incident frequency by a certain value related to the phase velocity of the resonantly scattering Fourier component of the surface shape. The experimentally observed dependence of the scattered intensity on frequency and the theoretically predicted one are very much alike.  相似文献

The author tested 3 theorems from his own book: (a) successful leadership is related more to ability in effective compared to ineffective groups, (b) successful leadership is related more to esteem in effective compared to ineffective groups, (c) discrepancies between esteem and self-esteem are manifested in unsuccessful leadership. "The 51 groups of ROTC cadets, each evaluating 10 problems, provided data concerning 510 discussions. These 510 discussions were divided into the 255 most publicly effective discussions and 255 least publicly effective. Then, the 1250 measures of relative success as a leader drawn from the 255 effective discussions among five members each were correlated with their scores for initial accuracy." The data were interpreted to substantiate all 3 theorems. From Psyc Abstracts 36:01:3GF20B. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Acidosis, alkalosis, and aqueous humor dynamics in rabbits   总被引:1,自引:0,他引:1  
Systemic acidosis induced by intravenous administration of hydrochloric acid lowered intraocular pressure in unanesthetized rabbits. Aqueous humor flow was reduced by approximately 50%, as measured by the iodide method and as calculated from tonographic data. Outflow facility, episcleral venous pressure, plasma osmolality, blood pressure, pulse, and body temperature were not altered by systemic acidosis. Systemic alkalosis induced by intravenously administered sodium bicarbonate was associated with an increased intraocular pressure. Aqueous humor flow following systemic alkalosis was increased by approximately 100%, as measured by the iodide method and as calculated from tonographic data. Alkalosis was not associated with alterations in outflow facility, episcleral venous pressure, plasma osmality, blood pressure, pulse, or rectal temperature.  相似文献

Measurements are presented of the thermopowerS of pure Al and dilute Al alloys from 2 to 6 K in magnetic fields up to 20 kG. For all samples the data are consistent with the equationS(H)=A(H)T+B(H)T 3 , allowing a separation of the electron diffusion thermopower componentS e (H)=A(H)T from the phonon-drag componentS g (H)=B(H)T 3 . Zero-field characteristic values ofS e were obtained for the impurities Cu, Cd, Tl, and Sn:S e (Cu) =–0.6T×10–8 V/K;S e (Cd)=–4T×108 V/K;S e (Tl)=–3T×108 V/K;S e (Sn) =–2T×108 V/K. The phonon-drag coefficientB was found to vary from impurity to impurity, a variation attributed to anisotropic electron-impurity scattering. Upon application of a transverse magnetic field,A(H) was found first to become more positive, and then to saturate in value at high fields. The quantity A=A(H)–A(H=0) was found to be very nearly the same for all impurities, varying in value only from 2.1–2.6×108 V/K. Both the general behavior ofA(H) and this magnitude for A are shown to be determined primarily by the form of the Fermi surface of pure Al.B(H) was also observed to vary with magnetic field. This variation is tentatively attributed to a combination of a changing importance with magnetic field of electrons in the second and third Brillouin zones of Al and anisotropic electron-impurity scattering, but no detailed explanation is yet available. Finally, the Wiedemann-Franz ratio of an impure Al-Cu sample is found to have the value 2.43 5 ±0.02×108 W·/K 2 at 4.5 K, independent ofH up to 20 kG, the highest field used. This value is in good agreement with the expected value :L 0 =2.45×108 W·/K 2 .This work was supported in part by the U.S. Atomic Energy Commission under Contract No. AT(11-1)-1247 and in part by the N.S.F. under Grant No. GH-34124. Based primarily upon a thesis submitted by one of us (R.S.A.) in partial fulfillment of the requirements for the Ph.D. degree at Michigan State University.  相似文献
