Psychotherapy with Holocaust survivors.

Examines the specific tasks and goals of psychotherapy in treating survivors of massive psychic trauma, emphasizing the re-emergence of the internal representation of the relationship between self and other. Establishment of an empathic dyad between patient and therapist and reconstruction of external memory must occur before the therapist can successfully assume a more traditional interpretive role. Clinical examples illustrate the implications of therapeutic work with survivors and with children of survivors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Overview of the Plasma Science and Innovation Center (PSI – Center)

The principal goal of the Plasma Science and Innovation Center (PSI – Center) is to achieve significantly improved computational predictive capability for smaller-scale devices. This is being accomplished through the refinement of existing computational tools through adding sufficient physics modeling, boundary conditions, and geometric capabilities while benchmarking results against experimental data. The work emphasizes the modeling needs of emerging concept (EC) experiments, but improved simulation capabilities for all innovative confinement concepts (ICC) are expected. A special emphasis is placed on physics effects that may extend beyond the standard analysis applied to the mainline programs.     

Calculation of light distribution in optical devices by a globalsolution of an inhomogeneous scalar wave equation

A numerical scheme is suggested for solving the scalar wave equation for optical devices characterized by a z-dependent refractive index. The homogeneous wave equation is converted into a single-column inhomogeneous linear system by applying imaginary (absorbing) boundary potentials at the device boundaries. The imposed absorbing boundary conditions enable discrete representation of the device on a compact grid. Our scheme is based on applying an efficient sparse preconditioner to the linear system, which enables its global solution (i.e., simultaneously for all z values) by fast iterative methods, such as the quasi-minimal residual algorithm. A single solution of the inhomogeneous equation with the imaginary boundary operators allows the calculation of mode-specific as well as region-specific light-intensity coupling probabilities for initial mode of interest. Numerical examples illustrate the usefulness of the suggested scheme to the optimization of optical devices     

Pyrimidinoceptor potentiation by ATP in NG108-15 cells

Regulation of inositol phospholipid hydrolysis by UTP and UDP in neuroblastoma x glioma hybrid cell line NG108-15 was potentiated in the presence of ATP. The effect of ATP was dose dependent and shifted the EC50 value for these uracil nucleotides up to three powers of magnitude, having no influence on the maximal value of the response. Adenine nucleotides (ADP, AMP, adenosine 5'-O-(3-thiotriphosphate) (ATPgammaS), beta,gamma-methyleneadenosine 5'-triphosphate (betagammaMeATP), 3'-O-(4-benzoyl)benzoyl ATP (BzATP) and 3'-deoxyadenosine 5'-O-(1-thio)triphosphate (dATPalphaS)) as well as adenosine, had no influence on the pyrimidinoceptor response. The potentiation effect was abolished by excess of EDTA. The results were in agreement with the hypothesis of pyrimidinoceptor affinity regulation via extracellular phosphorylation of the receptor protein, initiated by ATP. This mechanism may have physiological implication for functioning of uracil nucleotides as endogenous signaling molecules.     

Design and optimization of a diode-pumped fiber-coupled yb:er glass waveguide laser

An adaptive simulated annealing optimization algorithm is used to derive laser rate equation and waveguiding models with which the best design for a diode-pumped fiber-coupled, Yb:Er glass waveguide laser can be determined. Material parameters that correspond to commercially available laser-glass and diode-pump sources are used in this study. Given a continuous-wave 300-mW pump at 977 nm, approximately 48 mW of power at 1540 nm can be coupled into the LP(01) mode of an optical fiber. Fabrication and alignment tolerance analyses are presented.     

Postfailure reflectivity/impulsivity and spontaneous attention to errors.

We tested the idea that paying close attention to errors leads to improved performance on an inference task. We operationalized "attention to errors" as postfailure reflectivity, the ratio of the mean postfailure and post-success latencies on a self-paced inference task, where the interstimulus interval was subject controlled. Subjects were 9-, 10-, 11-, and 12-year-old children (N?=?378). Results reveal that (a) postfailure and reflectives show high cognitive performance during their initial exposure to the inference task; (b) postfailure impulsives have lower scores than postfailure reflectives on IQ, Raven, a test for attentional capacity, an arithmetic test, and teacher's evaluations in percentiles; and (c) "fast" versus "slow thinkers," as defined by J. Kagan's (1966) cognitive style construct, do not form homogeneous groups: fast–accurate children are postfailure reflective, and slow–inaccurate children are postfailure impulsive.

Long-term forecasting of smooth approximations to the load duration curve

This paper presents a methodology for long-term forecasting of smooth approximations to the load duration curve. The forecast results, when the approach is empirically implemented, are extremely good. Finally, while the application is limited to a functional approximation that has previously been used, there isn othing to deter its adaptation to other specifications.     

Implicit leadership theory as a determinant of the factor structure underlying supervisory behavior scales.

Examined implicit leadership theory (preconceptions about the patterning of leadership variables) in 235 college students. Ss completed the Survey of Organizations questionnnaire on a fictitious "Plant X" about which they were given little information. Factor analysis, performed on the items purported to measure 4 leadership factors, resulted in the conceptualized factor structure. Since no information was given regarding supervisory behavior in Plant X, the factor structure was attributed to an implicit leadership theory. Factor analysis on subsamples indicated the factor structure could not be attributed to either experience in organizations or previous instruction in management. It is suggested that responses to questionnaires regarding organizational variables may be contaminated by implicit theory and that multitrait-multimethod procedures may be required to validate questionnaires.
