Program evaluation in Canadian rehabilitation facilities for physically disabled persons: A national survey.

Surveyed the program-evaluation practices of 64 Canadian rehabilitation facilities (RFs) serving physically disabled children and/or adults. Of 14 program evaluation activities assessed, most RFs had implemented fewer than half as of mid-1982, although 62% of the RFs reported that they planned to implement additional evaluation elements by the end of 1983. Mean differences in current and planned evaluation activity levels between RFs located in different regions, serving different age groups, or of different facility types were modest.

Divergence control for distributed database systems

This paper presents distributed divergence control algorithms for epsilon serializability for both homogeneous and heterogeneous distributed databases. Epsilon serializability allows for more concurrency by permitting non-serializable interleavings of database operations among epsilon transactions. We first present a strict 2-phase locking divergence control algorithm and an optimistic divergence control algorithm for a homogeneous distributed database system, where the local orderings of all the sub-transactions of a distributed epsilon transaction are the same. In such an environment, the total inconsistency of a distributed epsilon transaction is simply the sum of those of all its sub-transactions. We then describe a divergence control algorithm for a heterogeneous distributed database system, where the local orderings of all the sub-transactions of a distributed epsilon transaction may not be the same and the total inconsistency of a distributed epsilon transaction may be greater than the sum of those of all its sub-transactions. As a result, in addition to executing a local divergence control algorithm in each site to maintain the local inconsistency, a global mechanism is needed to take into account the additional inconsistency Recommended by: Meichum Hsu     

Transmission Electron Microscopic Characterization of Ceramics Formed by Pyrolysis of Organometallic Polymer Precursors

Transmission lectron microscopy using bright-field and darkfield imaging and selected area electron diffraction was used to study ceramics pyrolyzed from a variety of organometallic polymer precursors. Determination of whether the pyrolyzed products were truly amorphous or microcrystalline was made and correlated to previous scanning electron microscopy or powder X-ray diffraction observations. Results indicated that most of the resultant as-pyrolyzed microstructures were amorphous, and that polymer pyrolysis presents significant opportunities for fabricating unique amorphous materials.     

"Collective induction: Social combination and sequential transition": Correction to Laughlin and Futoran.

Reports an error in "Collective induction: Social combination and sequential transition" by Patrick R. Laughlin and Gail C. Futoran (Journal of Personality and Social Psychology, 1985[Mar], Vol 48[3], 608-613). One sentence reads incorrectly on page 610. The correct sentence is provided in the erratum. (The following abstract of the original article appeared in record 1985-20078-001.) 240 undergraduates, as individuals and 4-person cooperative groups, attempted to induce a rule that partitioned a deck of standard playing cards into exemplars and nonexemplars. A trial consisted of (a) individual member hypotheses, (b) group hypothesis (omitted in individual conditions), (c) choice of any of the cards, and (d) feedback on the exemplar or nonexemplar status of the card. Ss were instructed to select cards to confirm or disconfirm the current hypothesis, or received no such instructions. Groups had significantly more correct final hypotheses, plausible final hypotheses, and overall plausible hypotheses than individuals. Performance was better for both individuals and groups under control instructions than either instructions to select cards to confirm or disconfirm hypotheses. Social combination analyses and sequential transition analyses indicated that the groups were remarkably able to recognize and adopt the correct hypothesis if and only if it was proposed by at least 1 group member on some trial. Thus, the superiority of collective induction over individual induction was due to superior hypothesis evaluation by groups rather than to superior hypothesis formation by groups.

Activity restriction and prior relationship history as contributors to mental health outcomes among middle-aged and older spousal caregivers.

In a sample of cancer patients (n?=?75) and spousal caregivers (24 men and 51 women), restriction in caregiver routine activities mediated associations between caregiving stress (patient symptom severity) and caregiver depressed affect and resentment. Moreover, the antecedents and affective consequences of caregiver activity restriction were consistent with the theory of communal relationships (e.g., M. S. Clark & J. Mills, 1979, 1993). If a relationship had been communal in the past (i.e., characterized by mutual concern for and responsiveness to one another's needs), activity restriction was predicted by intimacy and affectional loss (rather than by the severity of patient symptoms) and in turn predicted caregiver depressed affect. Among caregivers in less communal relationships, activity restriction was predicted by severity of patient symptoms (rather than by intimacy and affectional loss) and in turn predicted resentment of care recipients and the caregiving role.

Effects of task demands on implicit memory for object-location associations.

Examined the effect of task demands and the nature of the object probed on implicit and explicit memories for object location associations, in 5 experiments. 111 undergraduates probed objects (letters or symbols), 1 at a time, in 1 of 9 locations in a rectangle. They located or named the object. Each object was probed in the same location across 10 trial blocks, and then all the objects changed locations. Decrease or increase in naming times across trials was noted to find out the presence of priming for associations. Results show that implicit and explicit memory were affected differently by task demands. Priming could be obtained when the task engaged, but did not overtax, attentional capacity. Explicit memory performance was best when the task did not require much attentional capacity. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Contextually relevant aspects of meaning.

A series of six experiments investigated whether inferences about contextually relevant aspects of meaning were encoded into memory during reading. In all the experiments, subjects studied short paragraphs. Then, test sentences were presented that expressed relevant aspects of meaning that had not been explicitly stated in the paragraphs. For example, for a paragraph about searching for the correct color to paint a picture of a tomato, a relevant aspect of meaning would be that tomatoes are red. The test sentences were presented either immediately following the relevant paragraph or after a delay. With immediate testing, it was argued that the facilitation obtained in verification latency could result from processes occurring either when the context was read or when the test sentence was verified. With delayed testing, evidence was found to support the hypothesis that contextually relevant aspects of meaning are incorporated into the memory representation of the paragraph, but such evidence was obtained only when the retrieval environment encouraged the use of newly learned information in the decision process on the test sentence.
