Desperately seeking perfection: Christian discipleship and medical genetics.

The question of what, if anything, Christian theology as theology might contribute to ethical debates about appropriate uses of medical genetics has often been ignored. The answer is complex, and the author argues it is best characterized by an explanation of the analogous aspirations of the two: both have as their goal the perfection of the human being, both assert that the present disposition of the human body is on a fundamental level more often than not other than it ought to be, and both aspire to transform the present state of the body toward a future state in which present imperfections no longer exist. Given these analogous concerns, it would seem that one of the primary moral contributions that Christianity can make to debates about medical genetics is to ask whether and to what extent the Christian vision of embodied human perfection is compatible with the vision of perfection offered by the sciences pertaining to medical genetics. The author pursues a discussion of this analogy and its implications in this essay.     

EVALUATION OF A BRIEF STIMULUS PREFERENCE ASSESSMENT

We evaluated the utility of a brief (5-min) stimulus preference assessment for individuals with developmental disabilities. Participants had noncontingent (free) access to an array of stimuli and could interact with any of the stimuli at any time. Stimuli were never withdrawn or withheld from the participants during a 5-min session. In Experiment 1, the brief preference assessment was conducted for 10 participants to identify differentially preferred stimuli, and reinforcer assessments were conducted to test the reinforcing efficacy of those stimuli identified as highly preferred. In Experiment 2, a comparison was conducted between the brief preference assessment and a commonly used paired-stimulus preference assessment. Collectively, results demonstrated that the brief preference assessment identified stimuli that functioned as reinforcers for a simple operant response, identified preferred stimuli that were differentially effective as reinforcers compared to nonpreferred stimuli, was associated with fewer problem behaviors, and required less time to complete than a commonly used paired-stimulus preference assessment.     

Coping with Floods: Assessment, Intervention, and Recovery Processes for Survivors and Helpers

There has been unprecedented and destructive flooding in various parts of the United States during the past five years, particularly during the period of 1997 to 1998. Survivors' predictable emotional and physiological responses usually progress through five phases over a period of time toward either resolution or symptom development To preclude more severe and chronic symptoms, survivors should be debriefed by trained professionals within 48 hours, followed by more specific psychotherapy if they are more severely distressed. Finally, survivors and their families can benefit from participating in a unique twelve step program called SWWIM, which is described in detail in the paper.     

DISCOUNTING OF DELAYED REWARDS:

Abstract— In this study, children, young adults, and older adults chose between immediate and delayed hypothetical monetary rewards The amount of the delayed reward was held constant while its delay was varied All three age groups showed delay discounting, that is, the amount of an immediate reward judged to be of equal value to the delayed reward decreased as a function of delay The rate of discounting was highest for children and lowest for older adults, predicting a life-span developmental trend toward increased selfcontrol Discounting of delayed rewards by all three age groups was well described by a single function with agesensitive parameters (all R²s>94) Thus, even though there are quantitative age differences in delay discounting, the existence of an age-invanant form of discount function suggests that the process of choosing between rewards of different amounts and delays is qualitatively similar across the life span     

Innumeracy in social problems construction: Missing children,vanishing workers,and other statistical claims

Statistical claims are often central to the contemporary construction of social problems. The failure to subject these figures to critical analysis is a form of innumeracy, the inability to deal effectively with mathematical concepts. Two cases from the United States -estimates of the number of missing children, and projections for the workforce in the year 2000 -illustrate how the uncritical acceptance of inaccurate statistics can shape policy debates. Claimsmakers, the mass media, and the media audience all contribute to the innumerate interpretation of social statistics.     

The role of need level and/or need salience as moderators of the relationship between need satisfaction and work alienation-involvement

Contrary to previous findings documenting the importance of higher-order need satisfaction, a recent study by G. J. Gorn and R. N. Kanungo (Organizational Behavior and Human Performance, 1980, 26, 265–277) has indicated that satisfaction of lower-order needs may lead to job involvement if such needs are salient. Data from a heterogeneous sample of 632 employees from six organizations were used to test six hypotheses concerning the effects of need level (higher vs lower order) and need salience as moderators of the relationship between need satisfaction and alienation-involvement. Three different ways of operationalizing need saliency were used, including a replication of Gorn and Kanungo's procedure. Higherorder need satisfaction was correlated with alienation-involvement scores to a significantly greater degree than was lower-order need satisfaction, even for those for whom lower-order needs were most salient. Need saliency was not found to moderate the need satisfaction-involvement relationship when need level was controlled. Issues regarding the operationalization of “need salience” were discussed and a new measure of alienation-involvement (the A-I Scale) was introduced. Implications for further empirical investigations of the need saliency issue were noted, as was the universal application of job enrichment programs aimed at promoting higher-order need satisfaction.     

Attraction to a dissimilar stranger as a function of level of effectance arousal

An experiment was carried out to demonstrate that the relationship between attitudes of a stranger and attraction to that stranger can be mediated by effectance arousal and the consequent information search to reduce the arousal. The argument posited was that individuals under high effectance arousal produced by a confusing and ambiguous film would be attracted to dissimilar others as a source of information and uncertainty reduction. Results indicated that high levels of arousal produced greater attraction to a dissimilar stranger than to a similar stranger. This finding was reversed when an explanation was provided along with the confusing film, lending support to the uncertainty reduction position.     

On the prediction of confusion matrices from similarity judgments

Three observers viewed visual representations of eight complex sounds in both a pairwise similarity-judgment task and an identification task. A multidimensional scaling procedure applied to the similarity judgments yielded a three-dimensional perceptual space and the relative positions of the stimuli in that space. A probabilistic decision model based on weighted interstimulus distances served to predict well the confusion matrices of the identification task. Three conditions of the identification task, calling for identification of different subsets of the eight stimuli, led the observers to vary the weights they placed on the dimensions; they apparently adjusted the weights to maximize the percent correct identification. An additional group of 14 subjects, participating only in the similarity-judgment task, manifested the same three dimensions as the observers (corresponding to the locus of low-frequency energy, the locus of midfrequency energy, and visual contrast), and also a fourth dimension (corresponding to the periodicity, or waxing and waning, of the sound). Although not evident in the scaling analysis for the three observers, our utilization of the additional dimension increased significantly the variance accounted for in their identification responses. The overall accuracy of the predictions from a perceptual space to identification responses supplies a substantial validation of the use of multidimensional scaling procedures to reveal perceptual structure in demonstrating the ability of that structure to account for behavior in an independent task. The empirical success of this approach, furthermore, suggests a relatively simple and practical means of predicting, and possibly enhancing, identification performance for a given set of visual or auditory stimuli.     

A study of male and female soldiers' beliefs about the “appropriateness” of various jobs for women in the army

The purpose of this paper is to document the often discussed (e.g., Goldman, 1973) and recently initiated expansion of women's role in the U.S. Army and to present evidence regarding one aspect of soldiers' probable reaction to this expansion — viz., the extent to which soldiers believe certain military jobs are appropriate for women and, in particular, the extent to which these beliefs are related to respondent sex, rank, and expectation of leaving the Army before retirement.
