    Notes: Abstract An improved magnetic bead microrheometer based on phase contrast microscopy allowing high resolution measurements of local deformations within macromolecular networks is applied to study local viscoelastic properties of cross-linked actin networks. By embedding non-magnetic colloidal beads as probes into the networks, the spatial variation of the strain field within cross-linked actin networks can be mapped. Moreover, the Poisson ratio and shear modulus can be measured locally.

    Notes: The purpose of this meta-analysis was to quantify the effect of electrical stimulation on chronic wound healing. Fifteen studies, which included 24 electrical stimulation samples and 15 control samples, were analyzed. The average rate of healing per week was calculated for the electrical stimulation and control samples. Ninety-five percentage confidence intervals were also calculated. The samples were then grouped by type of electrical stimulation device and chronic wound and reanalyzed. Rate of healing per week was 22% for electrical stimulation samples and 9% for control samples. The net effect of electrical stimulation was 13% per week, an increase of 144% over the control rate. The 95% confidence intervals of the electrical stimulation (18–26%) and control samples (3.8–14%) did not overlap. Electrical stimulation was most effective on pressure ulcers (net effect = 13%). Findings regarding the relative effectiveness of different types of electrical stimulation device were inconclusive. Although electrical stimulation produces a substantial improvement in the healing of chronic wounds, further research is needed to identify which electrical stimulation devices are most effective and which wounds respond best to this treatment.

    Notes: This research showed that the validity of a biodata instrument developed and keyed within a single organization can generalize to other organizations. It also examines a criterion measure-rate of promotional progress-that has not been used extensively in biodata research, but has several characteristics that make its use attractive. The validity of the biodata component of the Manager Profile Record (MPR), developed and keyed within a single organization, as a predictor of rate of managerial progress was cross-validated on a sample of 7,334 managers and staff professionals in 24 organizations. Results indicate the MPR was a valid predictor of rate of promotional progress across all organizations and that validity did not vary greatly across organizations (p= .53, SDp= .05). The MPR was also a valid predictor for both sexes, as well as for managers of all age groups, lengths of company service, and education levels. These findings demonstrate that multiple-firm development and keying of a biodata instrument was not required for generalizable validity, and argue against the hypothesis of situational specificity. Suggestions for developing biodata instruments in single organizations that will generalize to other organizations include careful attention to the validity and reliability of criterion measures and developing validity at the item level.

    Notes: This study uses meta-analysis of an extensive predictive validity data-base to explore the boundary conditions for the validity of. the structured interview as presented by McDaniel, Whetzel, Schmidt, and Maurer (1994). The interview examined here differs from traditional structured interviews in being empirically constructed, administered by telephone, and scored later based on a taped transcript. Despite these and other differences, this nontraditional employment interview was found to have essentially the same level of criterion-related validity for supervisory ratings of job performance reported by McDaniel for other structured employment interviews. These findings suggest that a variety of different approaches to the construction, administration, and scoring of structured employment interviews may lead to comparable levels of validity. We hypothesize that this result obtains because different types of structured interviews all measure to varying degrees constructs with known generalizable validity (e.g., conscientiousness and general mental ability). The interview examined here was also found to be a valid predictor of production records, sales volume, absenteeism, and job tenure.

    Notes: Abstract Short-chain unsaturated chiral methyl carbinols are identified as a new class of lepidopteran pheromone components. The natural female-produced pheromone of the banded apple pigmyStigmella malella (=Nepticula malella) (Stainton) (Lepidoptera: Nepticulidae) was identified to be a mixture of (S)-(E)-6,8-nonadien-2-ol and (S)-(Z)-6,8-nonadien-2-ol. For monitoring traps, a 10:3E:Z blend at 100–1000 µg is recommended. It is suggested that pheromones with similar structures may be specific to Nepticulidae and other related microlepidopteran families.

    Notes: Abstract In the August 1993 issue ofJournal of Applied Psychology, Deniz Ones, Vish Viswesvaran, and Frank Schmidt published a monograph on the validity of integrity tests as revealed by meta-analysis. They concluded that integrity tests have substantial and generalizable predictive validity for criteria of both overall job performance and counterproductive behaviors on the job (e.g., disciplinary problems, absenteeism, rule breaking, violence on the job, theft, etc.). During the Fall of 1992, the authors sent a preprint of this study to David Lykken of the University of Minnesota, stimulating the exchange of letters that is reproduced here. The doubts, concerns, and feelings about integrity tests expressed by Professor Lykken are likely to be shared by others. The responses by Professors Schmidt, Ones, and Viswesvaran attempt to show that these worries are unfounded.

    Description: {\bf Efficient eigenmode computation for the design of integrated optical chips.}The paper deals with adaptive multigrid methods for 2D Helmholtz eigenvalue problems arising in the design of integrated optical chips. Typical features of the technological problem are its geometric complexity, its multiscale structure, the possible occurrence of eigenvalue clusters, and the necessity of quite stringent required relative error tolerances. For reasons of sheer computational complexity, multigrid methods must be used to solve the discretized eigenvalue problems and adaptive grids must be automatically constructed to avoid an undesirable blow-up of the required number of nodes for these accuracies. In view of the problem specifications, an adaptive multigrid method based on Rayleigh quotient minimization, simultaneous eigenspace iteration, and conjugate gradient method as smoother is carefully selected. Its performance in the numerical simulation of a component of a rather recent optical chip (heterodyne receiver of HHI) is documented.

    Description: We present a general technique for constructing nonlocal transparent boundary conditions for one-dimensional Schrödinger-type equations. Our method supplies boundary conditions for the $\theta$-family of implicit one-step discretizations of Schrödinger's equation in time. The use of Mikusi\'nski's operator approach in time avoids direct and inverse transforms between time and frequency domains and thus implements the boundary conditions in a direct manner.
