Grading the ‘cultural literacy’ project

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.     

Isoluminance and contingent color aftereffects

In the typical induction of the orientation-contingent color aftereffect (CCAE), the stimuli are composed of elements that differ in both color and luminance. Three experiments are reported that show that chromatic contrast between stimulus elements is insufficient for the induction of the orientation-CCAE and that luminance contrast is necessary. These experiments expand on previous research concerned with the role of luminance contrast in the induction of orientation-CCAEs by eliminating alternative explanations.     

Psychometric Properties and Clinical Utility of the Scale for Suicide Ideation with Inpatient Children

The purpose of the current study was to examine the psychometric properties and clinical utility of the Scale for Suicide Ideation (SSI) for children. The SSI was administered to 100 children who were hospitalized. Data were not used from 13 subjects due to the presence of a psychotic disorder or IQ less than 70, leaving 87 participants. The SSI was examined regarding its internal consistency, concurrent validity, construct validity, and factor structure when used with children. Based on the findings, the SSI appears to have adequate psychometric properties and can be used by clinicians and researchers examining children in an inpatient setting. Recommendations for clinicians are included to help make the SSI more functional in use for children.     

Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

HOW FAR SHOULD WE GENERALIZE?

Abstract— A conceptual model based on staffing theory was applied to previously collected survey data from a representative sample of American workers The model links organizational size, workload, work experience variables (felt responsibility and involvement, assessments of work associates), and work outcomes (job satisfaction, work self-esteem, stress symptoms) Path analyses indicated that the model fit data from all waged and salaried workers relatively well When the model was applied to subsamples of new and established employees and of employees from two contrasting occupational groups (professional-technical workers and operative workers), somewhat different patterns emerged The study illustrates the benefits of applying psychological theories across subdisciplines, as well as the limitations of generalizing research findings across different categories of workers We suggest that localized theories and fine-grained analyses of workplace events could help to make research more applicable to work settings     

Mental comparisons involving abstract attributes

Adult subjects in two experiments were presented pairs of stimuli that differed in varying degree on an abstract semantic attribute, and were required to choose the one with the higher value on the given dimension. Subjects in Experiment 1 chose the more pleasant member of a pair of pictures, concrete nouns, or abstract nouns. Those in Experiment 2, presented a pair of pictures or concrete nouns, chose the one whose referent had the higher monetary value. Theoretical interest centered on the effects of semantic distance, stimulus mode, and individual differences in imagery and verbal ability on choice time. In both experiments, response times (1) decreased with increases in semantic distance, (2) were faster for pictures than words (and for concrete than abstract words in Experiment 1), and (3) were faster for high- than for lowimagery participants. The results are completely consistent with a dual-coding (image vs. verbal) interpretation: Pleasantness and value, though conceptually abstract, are attributes of things rather than words, and they are accordingly represented in and processed by a system specialized for dealing with nonverbal information.     

A relay driver and contact closure sensing interface for an LSI-11 DRV11 parallel I/O board

A simple input and output circuit is described that allows users to sense contact closures and to drive relays from a Digital Equipment Corporation LSI-11 DRV 11 parallel interface board or a signal-compatible equivalent.
