Outcome of different treatment mixes in a multidimensional neuropsychological rehabilitation program.

Within a clinical demonstration program, 59 traumatically brain-injured patients were treated with 1 of 3 mixes of treatment. Mix 1 included cognitive remediation (CGR), small-group interpersonal (SGI) communication training, therapeutic community activities, and personal counseling. Mix 2 was similar to Mix 1 but stressed SGI exercises and eliminated CGR. Mix 3 emphasized CGR and eliminated SGI exercises. The efficacy of the treatment mixes was evaluated with performance on neuropsychological tests, improved independence in functional activities, measures of intra- and interpersonal functioning, and vocational outcome. Ss' participation in the program, irrespective of treatment mix, yielded improvements in (1) self-image, (2) quality of interpersonal relatedness and interaction, (3) involvement with others in naturalistic settings, and (4) vocational outcome. Overall, data point to the superiority of the balanced mix (Mix 1) over Mixes 2 and 3. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

AN ITERATIVE FILTERING ALGORITHM FOR NON-FOURIER FREQUENCY ESTIMATION

Abstract. We study an iterative filtering method to estimate frequencies of random Gaussian sinusoids in white noise. The method uses higher order crossings and takes advantage of a fixed point to guide the use of bandpass filtering in an attempt effectively to increase the signal-to-noise ratio. At each iteration the expected zero-crossing rate is estimated from independent time series. Convergence occurs with any prespecified probability less than one.     

Personal resources and political uprooting: The Israeli experience.

The authors assessed distress in Israeli society before and after Israel’s disengagement from Gaza and the northern West Bank during the summer of 2005. Random samples of 701 Israelis residing in various parts of Israel (Study 1) and 246 Israelis residing in Gaza and the northern West Bank who were to be uprooted (Study 2) were interviewed by telephone several weeks before the disengagement (T1), with 462 and 124 of these respondents, respectively, reinterviewed several weeks after the disengagement (T2). Anxiety related to the national and security situation was lower at T2 than at T1 in both studies. A personal resource, namely mastery–optimism, contributed negatively to both anxiety and hostility before the disengagement in both studies. In Study 1, it also predicted lower postdisengagement anxiety. The findings underscore the importance of mastery–optimism in the adjustment to threatening political events such as forced uprooting.

Determination of trace isoflavone phytoestrogens in biological materials by capillary electrochromatography

Capillary electrochromatography using a specialty monolithic matrix was utilized in developing a rapid and highly efficient separation of isoflavones in biological materials. Without a preconcentration technique, it is relatively easy to reach ppm-ppb concentrations of these compounds in soy-based foods and verify them structurally using a photodiode array detector. With on-column preconcentration, we were able to measure low-ppb levels in human serum. Using blood samples from human volunteers, whose diet was supplemented by a soy-based product, the method has been validated for high-throughput screening of isoflavones in clinical studies.     

Edit distance of run-length encoded strings

Let X and Y be two run-length encoded strings, of encoded lengths k and l, respectively. We present a simple O(|X|l+|Y|k) time algorithm that computes their edit distance.     

Clinical assessment of attachment patterns and personality disorder in adolescents and adults.

The relevance of attachment theory and research for practice has become increasingly clear. The authors describe a series of studies with 3 aims: (a) to validate measures of attachment for use by clinicians with adolescents and adults, (b) to examine the relation between attachment and personality pathology, and (c) to ascertain whether factor analysis can recover dimensions of attachment reflecting both interpersonal and narrative style. In 3 studies, experienced clinicians provided psychometric data using 1 of 4 attachment questionnaires (2 adolescent and 2 adult samples). Attachment dimensions predicted both personality pathology and developmental experiences in predictable ways. Factor analysis identified 4 dimensions that replicated across adolescent and adult samples on the basis of a combination of interpersonal and narrative indicators: secure, dismissing, preoccupied, and incoherent/disorganized.

Reduction of polarization in electrodialysis by ion-conducting spacers

A new method to decrease polarization in electrodialysis is suggested, with the aid of ion-conducting spacers. Spacers were prepared and tested. It was found that high current efficiency can be preserved at high current densities, in the present experiments up to 30 mA/cm² for a 0.011 N dialysate. Resistance of the dialysate compartment was lower than that corresponding to a homogeneous layer of solution for dilute dialysates. An open stack design made possible by the spacer is discussed.     

On high-speed computing with a programmable linear array

It has been observed by many researchers that systolic arrays are very suitable for certain high-speed computations. Using a formal methodology, we present a design for a single simple programmable linear systolic array capable of solving large numbers of problems drawn from a variety of applications. The methodology is applicable to problems solvable by sequential algorithms that can be specified as nested for-loops of arbitrary depth. The algorithms of this form that can be computed on the array presented in this paper include 25 algorithms dealing with signal and image processing, algebraic computations, matrix arithmetic, pattern matching, database operations, sorting, and transitive closure. Assuming bounded I/O, for 18 of those algorithms the time and storage complexities are optimal, and therefore no improvement can be expected by using dedicated special-purpose linear systolic arrays designed for individual algorithms. We also describe another design which, using a sufficient large local memory and allowing data to be preloaded and unloaded, has an optimal processor/time product.An earlier version of this paper was presented at Supercomputing '88.This work was partially supported by ONR under the contract N00014-85-K-0046 and by NSF under Grant Number CCR-8906949.
