The development of consultation skills lags far behind the development of counseling skills in most counselor education programs. Some of the reasons why consultation training is not emphasized are examined, and some remedies are suggested. 相似文献

The development of expert and decision support systems requires the collection, organization, codification, and storage of a body of specialized knowledge. The development, using reconstructive methods, of two such knowledge bases, the first containing the current scientific literature and the second containing an expert’s knowledge, is described for an automated decision support system, the Mental Retardation-Expert. This system provides practitioners with assistance in the treatment of aggressive, self-injurious, and destructive behaviors displayed by individuals with mental retardation or developmental disabilities. The average interobserver reliability of the expert knowledge base ranged from 92.5% to 95.0% when calculated across four clinicians’ assessments of 31 abstracted cases. 相似文献

In an attempt to account for morale and job satisfaction among 314 nurses, this study investigated the influence of work-related and interpersonal variables. Morale on the unit was directly related to supervisor support, co-worker relationships, and work recognition. Personal morale was accounted for by recognition, physical environment, the job itself, and pay. Job satisfaction was predicted by personal morale, work commitment, job clarity, work pressure, and innovation. Suggestions for improving nurse morale and job satisfaction are made. 相似文献

Body image or body images?: Comparative, multidimensional assessment among college students 总被引:2,自引:0,他引:2
A major criticism of research on body image concerns the dubious assumptions of the unidimensionality of the construct and the equivalence of body-image measures. Our study of 125 male and female college students compared multiple measurement methods within each of two modalities of body image: (a) perceptual (body-size estimation) and (b) attitudinal (body-image affect and cognition). Clinically relevant indices of psychological adjustment and eating disturbance were included. Results clearly supported the distinction between attitudinal and perceptual modalities of body image and indicated more convergent and discriminant validity for the former than for the latter. Whereas one method of assessing size-estimation accuracy and most body-image attitudes produced relationships with maladjustment, only attitudinal body image and perceptual, self-ideal discrepancy measures were significantly linked to eating disturbance. Relationships were generally more consistent for women than for men. Implications are discussed in the context of extant and future research on body image with clinical and nonclinical populations. 相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise. 相似文献

Proofs and Refutations is Lakatos's masterpiece. This article investigates some of its central themes, in particular: the nature of proofs ('Proofs do not prove, they improve'); the nature of definitions (real, not nominal); and the consequences of all this for ontology (platonism vs Popper's World Three). 相似文献

Summary When a line (the pointer) is collinear with a dot, the addition of a second line (the induction line) contiguous with the dot or near it may cause the pointer to appear to be collinear with a point further along or nearer to the induction line. The geometrical relations upon which this effect, which we call attraction-caused misalignment, depends have been studied with the Obonai and Wundt-Loeb (Hotopf, 1981; Hotopf & Brown, 1988) figures. Drawing upon the studies of misalignment in the Morinaga figure carried out by Restle (1976), Day, Bellamy, and Norman (1983), and Day and Kasperczyk (1985), as well as upon two new experiments, we show that misalignment in the Morinaga figure is also attraction-caused misalignment, as previously defined. We conclude with a discussion of a number of theories that aim at accounting for attraction misalignment. 相似文献

Multidimensional scaling (MDS) was used to compare perceptual maps for 10 synthetic English vowels in humans and Old World monkeys (Macaca fuscata andCercopithecus albogularis). Subjects discriminated among the vowels using a repeating background procedure, and reaction times were submitted to an MDS analysis to derive measures of perceived similarity. The dimensions that emerged related to the frequencies of the first(F1), second(F2), and third(F3) formants. Human data indicated a good match to previous MDS studies using rating procedures or confusion matrices: The dominant dimension mapped onto vowelF2, the phonetically most important formant, and the second and third dimensions mapped ontoF1 andF3, respectively.For monkeys, equal weightings occurred forF1 andF2, andF3 was not clearly represented. Monkey sensitivity to the formants appeared to relate to formant amplitudes. If monkeys are giving an accurate representation of the psychoacoustic relations among the formants, then our human results suggest that species-specific mechanisms, reflecting the salience of the phonetic feature of advancement, may contribute to vowel coding in humans. 相似文献
