Electrochemical Methods for Investigating Catalysis by Semiconductors

Over the past two decades there has been a large effort to establish a relationship between the catalytic and electrical properties of solids.     

Adherence-health status relationships in childhood diabetes.

Examined the relationship between adherence (ADH) behavior (to a diabetes regimen) and health status in 78 6–19 yr olds with insulin-dependent diabetes mellitus. 13 ADH measures were grouped into 6 ADH factors (Injection, Exercise, Diet Type, Testing/Eating Frequency, Calories Consumed, and Concentrated Sweets). Prevailing glucose levels were indexed, and fasting triglycerides (TRIG) and total cholesterol (CHOL) assays were used to estimate lipid metabolism. Adolescents were generally less adherent than younger Ss. Only Calories Consumed showed any predictive power. No significant regression equations emerged for CHOL. In contrast, TRIG was significantly associated with most ADH factors; in all cases, ADH interacted with the Ss' metabolic status, suggesting that ADH had different effects for Ss in good vs poor diabetes control.

Age differences in free recall and subjective organization.

Previous studies concerned with subjective organization occurring during free-recall learning have not provided consistent evidence for a hypothesis of organizational deficiency in the elderly. To assess the role of recall conditions in this discrepancy, the free-recall learning of younger and older adults was examined under conditions where the recalled words were either visible or not visible. Also, 5 measures of subjective organization, including measures used in earlier studies, were used to assess the role of measurement factors in producing the inconsistent findings. Younger adults, regardless of recall condition, recalled more words and showed more subjective organization than did the older adults with each of the measures. List length, rather than type of recall trial or measure of subjective organization, seems to be responsible for the conflicting findings obtained by other investigators.

Sequential and maximally parallel multiset rewriting: reversibility and determinism

We study reversibility and determinism aspects and the strong versions of these properties of sequential multiset processing systems and of maximally parallel systems, from the computability point of view. In the sequential case, syntactic criteria are established for both strong determinism and strong reversibility. In the parallel case, a criterion is established for strong determinism, whereas strong reversibility is shown to be decidable. In the sequential case, without control all four classes—deterministic, strongly deterministic, reversible, strongly reversible—are not universal, whereas in the parallel case deterministic systems are universal. When allowing inhibitors, the first and the third class become universal in both models, whereas with priorities all of them are universal. In the maximally parallel case, strongly deterministic systems with both promoters and inhibitors are universal. We also present a few more specific results and conjectures.
