EVALUATION OF AN INPATIENT PROGRAM AIMED AT PREPARING “HARD-TO-PLACE” CHRONICALLY MENTALLY ILL FOR THE COMMUNITY

A program designed to prepare long-stay “hard-to-place” psychiatric inpatients for successful community placement was evaluated. Fifteen patients in the Intensive Learning Center (ILC) program were assessed at 5- and 10-month intervals following baseline. In addition, their functioning was compared to a criterion related comparison group of 26 patients who had been transferred to community placements 18 months earlier. Two informant driven measures were used: The Rehabilitation Evaluation of Hall and Baker (REHAB), (Baker & Hall, 1988) and, Adaptive Behavior Scale (ABS), (Nihira, Foster, Shellhaas, & Leland, 1975). The results indicated significant improvement in the ILC patients adaptive functioning after 5 months, but this improvement was not consistently sustained at the 10 month follow-up. Comparisons between the ILC and community groups were made at 10 months and suggested considerable overlap in functioning between the two groups. The implications of the findings for program development and implementation as well as for discharge planning are discussed.     

New agendas for agricultural research in developing countries: Policy analysis and institutional implications

This article argues that the goals of agricultural research in poor countries have changed substantially over the last four decades. In particular they have broadened from the early (and narrow) emphasis on food production to a much wider agenda that includes poverty alleviation, environmental degradation, and social inclusion. Conversely, agricultural research systems have proved remarkably resistant to the concomitant need for changes in research focus. As a result many, at both the national and international level, are under great strain. In terms of public policy the article goes on to suggest that shortcomings of existing conceptual approaches to technology development could be supplemented by adopting analytical principles that view innovation in systemic terms. An approach where flows of knowledge between institutional nodes is a key to innovative performance (the “National Systems of Innovation” approach) is suggested as one such conceptual framework that might help supplement conventional policy analysis. An earlier version of this paper was presented at a workshop “New Policy Agendas for Agricultural Research: Implications for Institutional Arrangements” held on 28 March 2000 at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, India. The workshop was supported by the UK Department of International Development (DFID) Crop Post-Harvest Programme as an output of the project “Optimising Institutional Arrangements.”     

Status,Gender, and Nonverbal Behavior in Candid and Posed Photographs: A Study of Conversations Between University Employees

Ninety-six male and female university employees (93% White, 6% African American, 1% Asian) were photographed in dyads while they conversed about working at their university (candid photographs) and again while they deliberately faced the camera (posed photographs). Eight nonverbal behaviors were coded from the photographs, and relative status was ascertained from a postexperimental questionnaire. Status differences were found for upward (chin-up) head tilt and for resting elbows on leg or furniture; candid versus posed differences were found for upward head tilt, smiling, and raising the eyebrows; and gender differences were found for smiling, erect posture, forward lean, and touching self. Interactions involving gender, candid/posed photographs, and/or status suggested limitations to generalizations about main effects.     

Vicarious desensitization of test anxiety

students fail in the university environment due to an inability to perform in testing situations because of anxiety associated with tests (Suinn, 1968). Systematic desensitization has been found to be effective in the treatment of test anxiety, and attempts are being made to improve both the efficiency and effectiveness of this procedure (Mann and Rosenthal, 1969; Suinn and Hall, 1970). This study evaluates the relative effectiveness of four methods of systematic desensitization in the treatment of test anxiety. Specifically, two changes were investigated which may lead to: (a) more rapid forms of treatment (massed treatment versus distributed treatment); (b) more easily administered forms of treatment (vicarious desensitization versus active desensitization).     

Evidence for auditory feature integration with spatially distributed items

Recent auditory research using sequentially presented, spatially fixed tones has found evidence that, as in vision for simultaneous, spatially distributed objects, attention appears to be important for the integration of perceptual features that enable the identification of auditory events. The present investigation extended these findings to arrays of simultaneously presented, spatially distributed musical tones. In the primary tasks, listeners were required to search for specific cued conjunctions of values for the features of pitch and instrument timbre. In secondary tasks, listeners were required to search for a single cued value of either the pitch or the timbre feature. In the primary tasks, listeners made frequent errors in reporting the presence or absence of target conjunctions. Probability modeling, derived from the visual search literature, revealed that the error rates in the primary tasks reflected the relatively infrequent failure to correctly identify pitch or timbre features, plus the far more frequent illusory conjunction of separately presented pitch and timbre features. Estimates of illusory conjunction rate ranged from 23% to 40%. Thus, a process must exist in audition that integrates separately registered features. The implications of the results for the processing of isolated auditory features, as well as auditory events defined by conjunctions of features, are discussed.     

Relationship between perceptual style and ability to reproduce a standard work task

The present study examined the relationship between perceptual style and perception of physical effort. Perceptual style of 10 men and 10 women was assessed by the rod-and-frame apparatus. Perception of physical effort was defined as the difference in heart-rate responses between a standard work task and the subject's self-selected task. Heart-rate response on the pre-selected standard work task on a cycle ergometer (600 kpm.min.-1) was extremely variable, ranging from 111 to 188 beats per minute (M = 153 +/- 23.5). However, average error between heart rate during the standard work task and the subjects' self-adjusted workload was extremely low (range 0 to 18 beats per minute; M = 5.4 +/- 5.5 beats per minute). Pearson correlation of .78 showed a moderate relationship between heart rate and rating of perceived effort, but was nonsignificant (-.12) between perceptual style and perception of physical effort. The data confirm the absence of a significant relationship between perceptual style (i.e., field dependence-independence) and ability to reproduce a standard work task. In addition, these results suggest that there has been possible bias in studies of relationships between heart rate and rating of perceived effort or workload and rating of perceived effort during incremental testing.     

Cosmology and therapy

Sociological concepts are used to demonstrate applications of views of the cosmos to everyday living. Optimal recovery in therapy is defined as increased participation and increased life-satisfaction in family and society, with meaningful motivation and orientation to the universe.Cosmology and therapy concepts are applied to five different kinds of marital relationships in order to clarify possibilities and define contrasts. Family processes which evolve as shifts in views of the cosmos, beliefs, and behavior occur are described. Strengths and weaknesses of this therapy are discussed, and attention is paid to ways in which beliefs provide motivation, meaning, and direction for behavior.     

Unilateral olfactory conditioning in 6-day-old rat pups

The potential that early olfactory learning might be laterally organized in the brain was investigated in 6-day-old rats. This hypothesis is based on the finding that the commissural systems that subserve bilateral olfactory communication do not mature until the second week of postnatal life. Pups were trained with pairings of cedar odor and intraoral infusions of milk while one nostril was occluded. Animals expressed a conditioned orientation towards cedar if tested with the trained nostril open. No such conditioning was observed if the untrained nostril was open during testing. Further, when individual pups received cedar odor/milk pairings with one nostril open and orange odor/milk pairings with the other open, they expressed a conditioned preference for orange when tested with the orange-trained nostril open, and a preference for cedar when tested with the cedar-trained nostril open. Classically conditioned oral responses (mouthing) also appeared to be lateralized. However, no such unilateral conditioning occurred with respect to behavioral activation, which is also conditioned in this paradigm. Increases in activity to the odor CS were observed regardless of whether the trained or untrained nostril was open during testing. These results suggest that in developing rodents, olfactory memories may be partly represented in structures that can be unilaterally accessed during training and testing. They provide a starting point for isolation of neural substrates of the olfactory conditioning process.
