On the costs of accessible attitudes: detecting that the attitude object has changed.

The present research examined whether individuals with more accessible attitudes have more difficulty detecting that the attitude object has changed. While being repeatedly exposed to photographs of undergraduates, participants either rehearsed their attitudes toward each photo or performed a control task. They then saw these original photos and computer-generated morphs representing varying degrees of change in an original. Participants in the attitude rehearsal condition required more time to correctly identify morphs that were similar to the original as "different" (Experiment 1) and made more errors in response to such morphs (Experiment 2). Experiment 3 revealed that participants with accessible attitudes perceived relatively less change; they were less likely to view a morph as a photo of a novel person and more likely to view it as a different photo of a person seen before. The costs and benefits of accessible attitudes are discussed.

Consumer education in discharge planning for continuity of care.

The need to establish continuity of care for patients in transition from the hospital; to community is essential for adequate community adjustment. The Resource Group model of discharge planning is based upon a consumer education model with emphasizes the responsibility of the individual in discharge planning. In these groups, the partial hospitalization program staff representative and the clinical pharmacist, in conjunction with inpatient clinical social workers, begin discharge planning with inpatients during the early phase of hospitalization. Increased utilization of partial hospitalization services has resulted in greater continuity of care.

Energy transfer between terbium and iron bound to transferrin: reinvestigation of the distance between metal-binding sites.

The addition of trivalent iron, gallium, and terbium ions to the metal binding sites of human transferrin has been investigated by fluorescence and spectrophotometric measurements. Results are consistent with the possibility that the addition of ferric nitrilotriacetate to apotransferrin does not lead to a random distribution of iron bound to the two metal-binding sites on the protein, but rather an asymmetric distribution with iron bound mainly to one of the sites. The subsequent addition of terbium leads to the binding of terbium ions to the vacant sites on monoferric transferrin molecules, and observations of the intensity of terbium fluorescence from such samples provides clear evidence of transfer of excitation energy from the terbium site to the iron site. These results lead to the estimate that the two metal-binding sites of human transferrin are separated by a distance of 25 +/- 2 A, in disagreement with an earlier report (Luk, C. K. (1971), Biochemistry 10, 2838) that the sites were separated by more than 43 A. Consideration of the dimensions of transferrin indicates that the two sites lie relatively close to each other on the macromolecule.
