Conversion within the Mexican-descent, Catholic community of the United States is a reinforcement of existing values through a recommitment to the worldview of this people by means of an explicit, personal and public retrieval of its kinetics achieved by an innovative adaptation of its formal themes. Three rites of this community's popular spirituality are analyzed in order to discern the crisis in each context of culture, Christianity, and the world which may occasion conversion.Kenneth Davis is working with the Hispanic team of the staff of the International Office of RENEW. He has recently been inducted into the Academy of Hispanic Catholic Theologians of the United States (AHCTUS).  相似文献

Although visuoconstructive impairment has been reported in both Alzheimer's (DAT) and Huntington's (HD) disease, there is little knowledge concerning how this cognitive deficit differs quantitatively and qualitatively in these two progressive dementias. To address this issue, the present study compared performances on the Clock Drawing Test (CDT: command and copy) of 25 DAT patients, 25 equally demented HD patients, and 25 elderly normal controls (NC). In the command condition, both patients groups were significantly impaired compared to the NC group. Although there was no significant difference between DAT and HD patients' total quantitative scores, a qualitative error analysis revealed a number of dissociations between the two patient groups. Graphic difficulties, very common in HD patients, were virtually absent in DAT patients; in contrast, conceptual errors were almost exclusively seen in DAT patients and were related to the severity of their dementia. Perseveration and "stimulus-bound" responses were also more frequent in DAT patients, and both groups made visuospatial errors. In the copy condition, the DAT, but not the HD, patients evidenced a marked improvement in performance. These results indicate that while both DAT and HD patients have significant visuoconstructive difficulties even in the early stages of their disorders, the specific cognitive processes underlying their quantitative impairments are quite different. It is possible that the DAT patients' conceptual errors are yet another indicator of the deterioration of their semantic knowledge.  相似文献

Although substantial legal difficulties can face anyone trying to recover compensation from counsellors for breach of their legal duties, such claims can in principle succeed. Counsellors ought to take particular care to provide a physically safe setting for the counselling session. Advice given to the client can lead to liability both to the client and to third parties who may be affected. The impact of the client's actions on third parties can justify, and less often compel, departures from confidentiality. The importance of keeping client records has to be balanced against legal obligations imposed on counsellors in various situations to make such records available for inspection by the client or third parties.  相似文献

A 3×2×2 incomplete factorial design was employed to test the effects of sex, dominance, and their interaction on leader emergence. The factors included dominance distribution (high/high, high/low, middle/middle), sex (male-female), and dyad composition (mixed sex-same sex). The subjects were all Caucasians and were pretested on the California Psychological Inventory Dominance Scale. The data revealed that dominance was a predictor of leader emergence in same-sex conditions where high-dominant individuals assumed the role of leader in much greater proportions than their low-dominant partners. In mixed-sex dyads, sex appeared to be a more potent predictor with males becoming leaders at levels greater than would be suspected given dominance levels.  相似文献

Measures of spatial cognition, neighborhood knowledge, and neighborhood use from the research described by Walsh, Krauss, and Regnier (1981) were examined to determine if laboratory tests of spatial cognition were significant predictors of older adults' use of their neighborhoods. The overall results show that laboratory-based measures of spatial cognition and subjects' knowledge of their neighborhoods are both significant predictors of their use of neighborhood goods and services. The ability to learn and remember the location and orientation of objects, when contextual cues were not provided at test, was more predictive of the participants' neighborhood use than either the participants' number of years in the neighborhood or their mobility. Spatial memory as measured by the Educational Testing Service Building Memory task predicted neighborhood knowledge, which was predictive of neighborhood use.  相似文献

Adult age differences were explored on 3 short tests of the ability to generate and manipulate mental images. Age-related decrements were found in all 3 tests and were especially marked on the Clock Test. The tests are all reliable, as shown by test-retest reliability coefficients. Correlations also revealed that the Brooks Letter Test and the East-West Test appear to tap one common underlying ability, whereas the Clock Test measured a somewhat different ability. The East-West and Clock tests, in particular, may provide rapid and easily administered assessments of age-related changes in aspects of mental imagery.  相似文献

Research into the victims of crime is of fairly recent origin and has been centred in America. However, a review of research into the experience of the elderly as the victims of crime, and their anxiety about crime, reveals a paradox. Numerous studies show that while the elderly are less likely to be the victims of crime than are the other age groups, they are among those who exhibit most anxiety over crime. The research is discussed in the context of theories of why the elderly appear as a low-risk group and in terms of an attempt to explain the paradox.  相似文献

Systems of care for children with serious emotional disturbance and their families have generally lacked intensive community-based programs. We describe three types of newly established community-based programs in New York State and present a general evaluation plan for determining which programs work for various children and their families. The three community-based programs are Intensive Case Management, Family-Based Treatment, and Family-Centered Intensive Case Management. Process and outcome evaluations are being conducted for each of these programs. These evaluations make use of common intake and termination instruments, based on a minimum data set, standardized assessment instruments, and a common logic model, thus facilitating the comparison of findings across evaluations.  相似文献
