Reducing inner-city women's AIDS risk activities: A study of single, pregnant women.

Abstract: Behavioral change reduces risk of HIV infection and development of AIDS. We compared 206 inner-city women who were randomly assigned to a 4-session AIDS-prevention group or to one of two controls, a health-promotion group or a no-intervention group. AIDS-prevention and health-promotion groups provided information, behavioral competency training, and social support. Only the AIDS-prevention group focused on AIDS-specific knowledge and skills. The AIDS-prevention group produced moderate, consistent increases in knowledge and safer sex behaviors in comparison with either the health-promotion or no-intervention group. Self-report and objective changes were sustained 6 months after intervention for both African-American and European-American women.

Verbal aggressiveness: Messages and reasons

Abstract: The nature of verbal aggression is discussed with an emphasis on its destructiveness. A need to learn more about people who are verbally aggressive is argued because past research has tended to emphasize the situation rather than the person. A study of 181 college students is reported which explored the types of verbally aggressive messages used, the types of messages received, perceptions of the hurt produced by the messages, and the reasons for using verbal aggression which differentiate high from low verbal aggressives. The results identified types of messages used, beliefs about hurt and reasons for use which distinguish high from low verbal aggressives. The results are discussed in terms of understanding the nature of trait verbal aggressiveness. Speculations are advanced as to why high verbal aggressives are prone to using self‐concept attacking messages.

On the limit sets of cellular automata

Abstract: The limit sets of cellular automata, defined by Wolfram, play an important role in applications of cellular automata to complex systems. A number of results on limit sets are proved, considering both finite and infinite configurations of cellular automata. The main concern of this paper is with testing membership and (essential) emptiness of limit sets for linear and two-dimensional cellular automata.

The cytochemical reduction of nitro blue tetrazolium as an index of pollen viability

Abstract: A B S T R A C T A new technique for estimating pollen viability utilizing Nitro Blue Tetrazolium (Nitro-BT) is given. Pollen of 16 taxa was studied and scored for stainability. A comparison was made between Nitro-BT-stained pollen samples and aniline-blue-lactophenol-stained samples, because the validity of the latter stain has been questioned in recent years. It is demonstrated that Nitro-BT can discriminate between pollens which have a capacity for oxidative metabolism, representing potential viability, and those which do not. Suggestions for pollen stainability studies are given. POLLEN stainability data, as indicated by Lawrence (1951), may be a valuable tool for the taxonomist in attempting to distinguish putative hybrids from nonhybrids. This is based on the fact that pollen of many hybrids is shrunken and flaccid and, therefore, nonstainable and nonviable. In contrast, viable pollen grains possess intact nuclear and cytoplaslmic material and stain readily with 12KI, aceto-carmine, and aniline (cotton) blue in lactophenol. The validity of pollen stainability tests has been questioned in recent years. King (1961) emphasized that the most widely used techniques for staining pollen grains give results which have not been associated with viability. Long (1959) indicated that the aniline-blue-lactophenol technique can be considered only as a rough indicator of relative fertility. Little difficulty is encountered in determining
