Accuracy of weightbearing at three target levels during bilateral upright stance in patients with neuropathic feet and control subjects

The purposes of this study were to (1) describe errors in weightbearing at three target levels for patients with neuropathic feet and control subjects, (2) compare the absolute errors at the three target levels between groups, and (3) identify predictor variables of errors in weightbearing by the neuropathic group. The groups of 26 subjects were matched for age and height. Weightbearing was measured with digital scales while subjects attempted to adjust their weight through a designated lower extremity to each target level (25, 50, and 75% of body weight). Analysis of variance indicated no significant difference in the percentage weightbearing between groups at the three target levels. There was a significant difference in errors made in weightbearing by the groups at the three target levels. Mean errors ranged from 8.5 to 9.7% for the neuropathic group and from 2.4 to 6.6% for the control group. The findings cast doubt on the utility (in the absence of feedback) of requesting individuals, particularly those with neuropathic feet, to weightbear at specific target levels.     

Distinguishing between conduct problem and emotionally disturbed students in secondary school: a five-instrument discriminant analysis

Five instruments, the Differential Test of Conduct and Emotional Problems, Louisville Behavior Checklist, Personality Inventory for Children, 16 PF Test, and Tennessee Self-concept Scale, were given to differentiate between 50 conduct problem and 48 emotionally disturbed students assigned in public school to secondary level classes for the severely emotionally handicapped. Discriminant analysis of each test's rate of classification germane to both a pre-assessment categorization as conduct problem vs emotionally disturbed and a post-assessment classification as no problem vs conduct problem vs emotionally disturbed vs combined problem is presented. The analysis indicated that the Differential Test of Conduct and Emotional Problems, Louisville Behavior Checklist, and Personality Inventory for Children can, with variable effectiveness, significantly classify adolescents into groups using such pre- and post-assessment information.     

Parent interaction after divorce: Comparison of mediated and adversarial divorce processes

The interactions and perceptions of two groups of divorcing parents using different dispute resolution processes were compared at final divorce and at 1 and 2 years post-divorce. Using objective and standardized measures, the effectiveness of a comprehensive divorce mediation process was contrasted to the more customary two attorney adversarial process. The 153 parents at final divorce were part of a larger, longitudinal study of 435 divorcing men and women who were followed from the beginning of divorce to 2 years post-divorce. Parents in the divorce mediation group reported less conflict during the divorcing period, and less conflict, more contact and communication, and a more positive attitude toward the other parent at final divorce, results which remained significant after controlling for several baseline group differences. The majority of differences favoring the mediation intervention continued through the first year after divorce, and disappeared by the 2 year post-divorce data collection. The nature of the mediation process is discussed in relation to these parental behaviors and attitudes.

Fourier components of moving gratings

In designing experiments in which the proximal stimulus is a moving grating (including cases in which the distal stimulus is stationary but eye movements play a significant role), one must consider the effects of the motion of the stimulus on its Fourier components in the spatiotemporal frequency domain. Some of these effects are unexpected and counterintuitive. For example, the Fourier components of a moving grating do not include its stationary (or “instantaneous”) spatial frequency. Thus there is no linear filter that can extract a stationary grating from a moving one. Several useful relations are given for analyzing such stimuli.     

Are high levels of religiosity inconsistent with a high valuation of science? Evidence from the United States,China and Iran

We asked whether high levels of religiosity are inconsistent with a high valuation of science. We explored this possibility in three countries that diverge markedly in the relation between the state and religion. Parents in the United States (n = 126), China (n = 234) and Iran (n = 77) completed a survey about their personal and parental stance towards science. The relation between religiosity and the valuation of science varied sharply by country. In the U.S. sample, greater religiosity was associated with a lower valuation of science. A similar but weaker negative relation was found in the Chinese sample. Parents in the Iranian sample, by contrast, valued science highly, despite high levels of religiosity. Given the small size of our United States and Iranian samples, and the non-probabilistic nature of our samples in general, we caution readers not to generalise our findings beyond the current samples. Despite this caveat, these findings qualify the assumption that religiosity is inconsistent with the valuation of science and highlight the role of sociocultural context in shaping adults' perception of the relation between religion and science.
