Success,social comparison,and self-assessment: Parents' midlife evaluations of sons,daughters, and self

The literatures on sex-role socialization and social comparison theory were used to predict how parents would evaluate the life success of adult sons and daughters and how parents' assessments of themselves would be influenced by comparisons with these children. Although parents (N=215) did not report different levels of life success for 291 adult sons versus 251 adult daughters, parental well-being was more closely tied to assessments of sons' success. In addition, although parents' reported that both sons and daughters had exceeded their own life success, theparent-child comparison with daughters was the better predictor of parents' well-being. Findings are discussed in terms of parents' individual development, family processes at midlife, and cohort differences between parents and their children.     

A systems analysis of the behaviors of schooling

Summary and conclusions Thus, the existing nonsystematic system, and the various vested interests associated with it, targets groups of students rather than individuals. Prior to the advent of a science of schooling, the tutorial approach associated with the privileged or ruling classes did not seem feasible for educating the masses, simply because there was no adequate science of behavior for the individual. Even after that science showed promise for pedagogy, there was still no systems-wide science for applying what was known to groups and organizations in which the individual was pivotal. In order to determine whether behavioral conceptions of schooling work on a larger scale, we must experimentally test whether or not thoroughgoing applications are feasible to educate the masses individually. Findings from 8this research can be used to design and modify systems of schooling that are measurably effective, workable year in and year out, automatically self-correcting, and beneficial to all of the parties involved. CABAS has demonstrated how such a system can work on a small scale; other attempts may show us how to make a large scale system work. We have not yet seen what man can make of man (Skinner, 1971, p. 215).     

Computing Cohen’s kappa coefficients using SPSS MATRIX

This short paper proposes a general computing strategy to compute Kappa coefficients using the SPSS MATRIX routine. The method is based on the following rationale. If the contingency table is considered as a square matrix, then the observed proportions of agreement lie in the main diagonal’s cells, and their sum equals the trace of the matrix, whereas the proportions of agreement expected by chance are the joint product of marginals. The generalization to weighted kappa, which requires an additional square matrix of disagreement weights, both matrices having the same order, becomes possible by the use of the Hadamard product-that is, the elementwise direct product of two matrices.     

Human sensitivity to temporal proximity: The role of spatial and temporal speed gradients

Estimates of temporal proximity (sometimes called time-to-collision) from random-dot flow patterns are shown to be based upon retinal speed, rather than upon changes in dot density. Neither the spatial nor the temporal gradient of motion is essential to the task, but estimates can be made from either alone. Performance is unaffected by the addition of rotational motion, suggesting that observers axe capable of extracting the radial component of motion, which contains all the relevant information, from complex stimuli.     

Diaphragmatic spasm: A neglected cause of dyspnoea and chest pain

The study included 17 patients, 12 women and 5 men, with a recurrent symptom complex involving chest pain and dyspnoea characterized by inability to get a full breath. Some attacks had subsided spontaneously. Others had lasted hours or days. When examined by fluoroscopy during an attack, each subject was found to have a nearly maximally contracted (flat) diaphragm. In some of them the attack was promptly interrupted by a small intravenous injection of sodium amytal. In others it could be aborted by a conscious effort at full expiration. The syndrome associated with diaphragmatic spasm is discussed in comparison with other noncardiac sources of chest pain and dyspnoea.
