A test of the proposition: We want to be esteemed most by those we esteem most highly.

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)     

Laxative-like effects of nonsteroidal anti-inflammatory drugs on intestinal fluid movement and membrane integrity

Certain nonsteroidal anti-inflammatory drugs (NSAID) of the fenamate chemical class are known to cause diarrhea in clinical use. Paradoxically, this action is shared by prostaglandins, against whose syntheses are inhibited by NSAID. This study was done to investigate the laxative potential of 5 NSAID (meclofenamate, flufenamate, mefenamate, indomethacin and aspirin). The ability to produce a laxative response was assessed by determining effects on fluid absorption in vitro in hamster everted sacs and by the enteropooling assay in hamster small intestine. In addition, the lytic action of these drugs on the erythrocyte membrane was determined to arrive at a possible mechanism of action. All of the NSAID, except aspirin, produced dose-related inhibition of fluid transport, similar to prostaglandin E1 and E2. The order of inhibition was flufenamate greater than meclofenamate greater than mefenamate greater than indomethacin. Like results were obtained when enteropooling was measured in vivo. Flufenamate and meclofenamate produced lumenal fluid accumulation comparable to two laxatives, dioctyl sodium sulfosuccinate and ricinoleic acid. Finally, the effects of these NSAID on fluid movement paralleled their lytic action on the erythrocyte membrane model, suggesting that NSAID may produce diarrhea in a manner similar to certain laxatives, by increasing mucosal permeability through membrane damage.     

Lifespace variables and managerial success.

Correlated lifespace measures with the discrepancies between original test battery forecasts (Miller Analogies Test, Nonverbal Reasoning Ability Test, Guilford-Zimmerman Temperment Survey, and Management Judgment Test) and subsequent managerial success on the job. Variables included the manager's perceived task challenge on his entry job (Modified Task Characteristics Questionnaire), his life change between test and criterion measurement (Schedule of Recent Experiences), his personality match with his first supervisor, and the success of his first supervisor. These served in combination for 140 Exxon managers (average age, 31 yrs) to account for an additional 22.7% of the variance in success after 5 to 7 yrs on the job when added to the validity of prediction (.63) by the Exxon Early Identification of Management Program battery of aptitude and personality assessments administered during the 1st 18 mo of employment. The equivalent of a multiple correlation of .79 was attained. (29 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Color Phenomena Associated With Energy Transfer in Afterglows and Atomic Flames

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.

Very high frequency radiowave scattering by a disturbed sea surface Part I: Scattering from a slightly disturbed boundary

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.     

Retrieval of aerosol refractive index from extinction spectra with a damped harmonic-oscillator band model

A new method for the retrieval of the spectral refractive indices of micrometer-sized particles from infrared aerosol extinction spectra has been developed. With this method we use a classical damped harmonic-oscillator model of molecular absorption in conjunction with Mie scattering to model extinction spectra, which we then fit to the measurements using a numerical optimal estimation algorithm. The main advantage of this method over the more traditional Kramers-Kronig approach is that it allows the full complex refractive-index spectra, along with the parameters of the particle size distribution, to be retrieved from a single extinction spectrum. The retrieval scheme has been extensively characterized and has been found to provide refractive indices with a maximum uncertainty of approximately 10% (with a minimum of approximately 0.1%). Comparison of refractive indices calculated from measurements of a ternary solution of HNO3, H2SO4, and H2O with those published in J. Phys. Chem. A 104, 783 (2000) show similar differences as found by other authors.     

Some aspects of attempted, successful, and effective leadership.

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)     

Acidosis, alkalosis, and aqueous humor dynamics in rabbits

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.     

The constitution and phase stability of overlapping melt trails in Ag- Cu alloys produced by continuous laser melt quenching

Coatings consisting of overlapping trails melted with a scanning CW CO₂ laser have been produced on Ag-Cu alloys with the following compositions: Cu 17 at. pct Ag; Cu 37 at. pct Ag; Cu 61.7 at. pct Ag; Cu 71.8 at. pct Ag; and Cu 82 at. pct Ag. The laser beam was scanned at a velocity of 34 cm s¹ and with an intensity of 3.6 MW cm^-2. Selected trails were examined by X-ray diffractometry, optical microscopy, and scanning electron microscopy in the as-irradiated condition and after annealing for various periods of time in the temperature range 100 to 450 ° C. Time-temperature-transformation diagrams based on the annealing studies are presented. Significant amounts of the metastable extended solid solution (γ) were observed in the Ag-rich alloy trails. The silver rich terminal solid solution (α) was also detected, formed probably by solid state precipitation. An α’ phase with lattice parameter lying between that ofy and α was also observed in the Cu 61.7 at. pct Ag alloy. A metastable equilibrium diagram has been constructed and is employed to interpret these observations. The most striking microstructural feature of the trails are bands marking sequential positions of the melt-solid interface. We propose that these bands are evidence for planar, oscillating - steady-state, interface motion. The observation of a periodic cellular breakdown of the planar interface in the Cu 61.7 at. pct Ag alloy is attributed to a diffusional instability previously predicted by Baker and Cahn.
