Demographic shifts, the further commercialization of the health and human services industry, and various economic trends point to a restructuring of the systems delivering services to the aged. Emerging are approaches that offer a broad range of services under the auspices of separate organizational entities. Called continuums of care, such organizational forms use single points of entry as mechanisms to control access to the array of available services. Using the life care community as the prime example, this article examines the operations of single-point entry organizations. The authors also explore the implications of such structures for the health and human services industry, noting their potential for stratifying the aged along the dimensions of health and income. 相似文献

As a consequence of the Consent Agreement reached between the Pennsylvania Association for Retarded Children and the Commonwealth of Pennsylvania in the United States District Court for the Eastern District of Pennsylvania, school of psychologists are finding themselves increasingly in the role of expert witness in due process hearings. The paper identifies a number of problems regarding the witness behavior of psychologists in these hearings and proposes some recommendations and resolutions. 相似文献

Two experiments were performed both of which involved the same-different comparison of pairs of alphabet letters. "Same" reaction times were obtained for both physical matches (e.g., AA) and name matches (e.g., aA). The results of both experiments supported the hypothesis that individual subjects would differ with respect to whether or not they based their physical matches on a comparison of verbal codes. In Experiment I, subjects differed in the size of their reaction time difference between physical and name matches, and in Experiment II, individuals differed with respect to whether or not the frequency of usage of the letters affected their reaction time for physical matches. In both experiments, the individual differences in verbally coding physical matches were related to Hock's (1973) individual differences distinction between subjects emphasizing analytic processes and subjects emphasizing structural processes. 相似文献

To investigate the precise mechanism of control of binocular rivalry, Ss were instructed to attend actively to whichever pattern was momentarily in the nonsuppression phase. Test stimuli were presented tachistoscopically for recognition in either phase of rivalry. Because the differential recognition between nonsuppressed and suppressed phases was no greater for an active condition than for a passive viewing condition, it was concluded that control is not mediated by varying the amplitude of the suppression effect. This result was consistent with control that is exercised by selecting the eye to receive a constant amplitude suppression. In addition, it was found that visual sensitivity of rivalry nonsuppression and nonrivalry were the same for the ocular dominant eye but different for the nondominant eye. 相似文献

Acquired enuretics (children who resume wetting after a period of dryness) have been distinguished from persistent enuretics (children who were never dry) in that the wetting of the former has been viewed as symptomatic of conflict and not modifiable by conditioning procedures. The present study compares these two types on measures of conditioning outcome and effectiveness, initial pathology and post-treatment adjustment. 相似文献

Studies of tachistoscopic word perception were reviewed under two theoretical headings: the structural approach, in which the variables of interest are linguistic relations among letters, and the lexical approach, where the interest is in the availability of words in lexical memory. The results of a recent tachistoscopic recognition study question the importance of lexical availability by finding no difference in performance between meaningful words and well-structured, pronounceable nonwords. In the present study, further comparisons between words and pronounceable nonwords were performed, and a meaningfulness effect was demonstrated. The generality of this finding was discussed, and alternative models accounting for the effect were considered. Two of these were capable of explaining structural effects as well as the meaningfulness effect: a translation model and a lexical discrimination net. 相似文献

This paper presents a test for determining significance of differences between means of samples which are drawn from positively skewed populations, more specifically, those having a Pearson Type III distribution function. The quantity 2npx

For two independent samples, the larger mean divided by the smaller mean, which distributes itself asF for 2n

When a lower theoretical score limit (c) exists which is not zero, the quantity (Mean —c) should be used instead of the mean in all calculations. 相似文献

Between 65 and 75 % of juvenile-justice involved (JJI) youth present with at least one behavioral health disorder. Many communities have developed diversion programs that provide behavioral health services to JJI youth, often in lieu of detention. A key component of successful diversion programming is accurate screening and assessment. The Ohio Scales, a validated instrument designed to track service effectiveness in clinical samples of youth, are now being used with juvenile justice populations. The purpose of this study is to validate the Ohio Scales in a JJI youth population (N = 2246). The population (ages 12–18) is derived from Ohio’s Behavioral Health Juvenile Justice Initiative, a diversion program for JJI youth with behavioral health issues. We conducted Confirmatory Factor Analyses (CFA) on all forms of the Ohio Scales (parent, youth and worker) to measure fit for one factor, four factor and four factor second order solutions. We also conducted an Exploratory Factor Analysis (EFA) on the Problem Severity factor in the youth form to determine the number of appropriate sub-factors. The EFA indicated that the Problem Severity factor should be broken into three hypothesized sub-factors: Externalizing, Internalizing and Delinquency. The CFA confirmed this solution. CFA results indicated the four factor second order solution fits superior to the other two solutions. Using the Ohio Scales Problem Severity measure as a three sub-factor measure may increase clinical applicability by allowing a clinician to specifically measure and target externalizing or internalizing issues during treatment. 相似文献
