What makes targets redundant?

Two letter-classification experiments that investigated target-redundancy effects on reaction time (RT) were conducted. Both experiments were replicated with choice reaction time (CRT) and go/no-go (GNG) procedures. In each experiment, there were two single-target conditions, one with a noise letter and one without. In one experiment, the letter classes were two letters that could be of either case. In the second experiment, each class consisted of two different capital letters. In both experiments, there were two redundant-targets conditions, one with identical targets and one with the different members of a class. In both of the GNG experiments, redundancy gains were obtained comparing the different-targets condition with the no-noise, single-target condition. Redundant stimuli are ones that lead to the same response. Visually different stimuli may be processed in parallel and jointly activate a response. GNG procedures are more sensitive than CRT in the investigation of redundancy effects.

Using an integrated physician-nurse medical record.

Of all the issues surrounding collaborative practice, the integrated medical record perhaps is the most controversial one for physicians. This article explains how a patient record system that integrates the observations, judgements, and actions of both nurses and physicians can facilitate nurse-physician communication and contribute to the care of the patient. It also explains some problems encountered with implementation and some ongoing concerns.

Biological values of the infant, juvenile, and adult agouti (Dasyprocta sp) with emphasis on microbial flora.

Normal values for intestinal flora were determined on four adult, two juvenile, and four infant agoutis (Dasyprocta sp) maintained at our institution. Serologic, hematologic, biochemical, and histologic observations were also made on these same agoutis, and serologic, microbiologic, and endoparasitic tests were made on serum and fecal samples from agoutis maintained at other institutions. Streptococci, lactobacilli and nonenteropathogenic Escherichia coli were isolated from cecal contents of all age groups. Gaffkya tetragena and Bacillus sp were recovered from infant agoutis, Proteus mirabilis from juvenile agoutis, and Proteus mirabilis and Micrococcus sp from adult agoutis. Infant agoutis showed marginal antibody titers to reovirus type 3 and Toolan's H-1 viruses, and Theiler's GDVII antibodies were detected in juvenile agoutis, but no antibody titers to murine viruses were found in the adult agoutis maintained at our institution. Hematologic, biochemical, and histologic data for these agoutis were comparable to those of other hystricomorph rodents. Serologic tests of the agoutis maintained at other institutions disclosed antibodies for GDVII virus in all of 17 animals tested, while marginal titers were found for Sendai virus in four and for reovirus type 3 in eight of the 17 animals. Only low incidences of pathogenic bacteria (Salmonella, Pseudomonas, and Citrobacter) were isolated from the agoutis maintained elsewhere. The endoparasites found in these agoutis were Ascaris, Toxascaris, Strongyloides, Trichuris, and Trichomonas.

Murine virus susceptibility of cell cultures of mouse, rat, hamster, monkey, and human origin.

Studies were initiated to determine the practicality of using various tissue cultures for the propagation of murine viruses isolated from laboratory animals. The cytopathogenic effects of 10 murine viruses known to cause disease in laboratory rodents were compared in monolayer cultures of L929, BHK-21, WI-38, BSC-1, and Vero cells. The susceptibility of primary hamster embryo, hamster kidney, mouse embryo, mouse kidney, and rat embryo cell cultures was also tested. Seven of the viruses produced effects in at least 1 of the cell substrates. The remaining 3 viruses, namely H-1, K, and mouse hepatitis, produced no effects in the cell cultures tested.
