Recruitment of minority group students and women.

Examined recruitment efforts of 65 fully approved American Psychological Association doctoral programs in clinical psychology. Results suggest that the programs were ambivalent about the recruitment of minority groups and of women in particular. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-consistently computed magnetization patterns in thin magnetic recording media

A model involving head motion is given for self-consistently computing magnetic recording medium magnetization patterns. The reduction in demagnetizing field due to the presence of the high-permeability head structure is included, as is record head removal, read head replacement, and computation of the readback voltage. The model is capable of handling an arbitrary record current waveform. Optimum record-current amplitude for nonreturn to zero (NRZ) digital recording is first determined, and then single-, double-, and quadruple-transition computations are performed using two different values of hysteresis loop squarenessM_{r}/M_{s}and both linear and exponential current reversals. Results are primarily for the Karlquist fringe field, but the recording properties of a head exhibiting regions in which the fringe field reverses sign are also briefly investigated.     

DIFFUSION COEFFICIENT OF OXYGEN IN LIQUIDS

The laminar dispersion of a solute in a capillary tube is used to measure diffusion coefficient of oxygen in liquids. A Polarographic type oxygen microelectrode is used to detect the pulse. Such a procedure overcomes the problems of measuring dissolved gases and makes it possible to apply this well known technique to oxygen-liquid systems. The results are in agreement with literature values     

Acute pretreatment with pyrazole and ethanol: effects on glucose-induced changes in insulin and glucagon

Ethanol suppressed, in a dose-related manner, glucose-induced insulin (IRI) release and thus delayed the disappearance of glucose from the blood of rats. Pretreatment with pyrazole, an alcohol dehydrogenase inhibitor, exacerbated the effect of ethanol on IRI release, glucose tolerance and glucagon (IRG) release. These results suggest that ethanol produces glucose intolerance by inhibiting glucose-induced IRI release and by augmenting IRG release. Moreover, these findings indicate that ethanol does not have to be metabolized completely in order to produce these effects.     

Readmission discount factors in program evaluation. An output value analysis of an adult psychiatry program

The application of output value analysis, a type of benefit/cost analysis, to a psychiatric patient population is reported. A method for discounting the value of the program if a patient was readmitted within a year after discharge was introduced. The application of this discount factor reduces the value produced by the program and thereby reduces both productivity and effectiveness indices. When applied to groups known to differ in readmission rates, such as first admissions and readmissions or voluntary and involuntary admissions, the discount factor can accentuate group differences markedly. When selected diagnostic groups were compared, the discount factor could even reverse the relative standing of the groups.     

Void formation and solute segragation in Ti-14.4 at% Al

An alloy of Ti-14.4 at% Al was irradiated with 3.0 MeV ⁵⁸Ni ions at temperatures near 600°C and to damage levels from 1.3 to 14.7 dpa. TEM examination of these specimens showed the damage produced voids, dislocation loops and network dislocations. The undersize aluminum solute atom segregated to the voids, grain boundaries and the irradiated surface, causing enhanced precipitation of γ'-Ti₃Al at these sinks for point defects. Shells of $\text{α}{}_2\text{~ 75}\text{A}\text{?}$ thick coated the voids and a continuous film of γ' was observed on the irradiated surface and on some grain boundaries. The surface film of α₂ contained $\text{1}\text{3}\text{a 〈11}\text{2}\text{?}\text{0〉}$ antiphase boundaries. Voids have not been previously observed in irradiated hcp Ti and this is the first observation of substantial irradiation-induced segregation in an hcp alloy.
