Venezuela has experienced quite a rapid rate of change at mid century but has not been able to attain real economic development. Yet the desirability of progress is a commonly shared value, although there are important differences within the society; for example, in the ways in which work is conceived, or the degree to which the common Latin American values are ascribed. Besides, the concern with power, which is also identified as important within Venezuelan society and often gets combined with the socio-centric values into ‘political partisanship’, is a factor affecting organizational functioning, particularly in the public sector. Examples are given of unsuccessful and successful organizations, pointing out the need to take into account the commonalities and diversities in values identified within the society in the search of organizational alternatives more viable within the particular context.  相似文献

Heart rate and motor responses were recorded in cats of different ages during classical conditioning. A deceleratory-acceleratory heart rate pattern observed during the CS-US interval in one and four-week-old kittens is an alpha conditioned response, a potentiated original response to the CS. At eight weeks of age two new distinct patterns of pure acceleration or pure deceleration are acquired during conditioning and in the absence of motor learning. At 12 weeks of age and in adult subjects, heart rate patterns during the CS-US interval become more complex and conditioned motor responses can be observed. A covariance of HR acceleration and motor responses during the CS-US interval is absent in eight-week-old subjects, but quite high in 12-week-old subjects and adult cats. The data are interpreted as suggesting separate elicitatory mechanisms of HR and motor responses which may show synchrony later in ontogeny.  相似文献

The relationship between operant level (base rate) and asymptotic reinforced instrumental responding was investigated in several contingencies in which licking was contingent upon running, under different FR schedules. For Group I the relationship was examined by selecting rats who naturally differed in their running base rates and for which the licking base rates were equivalent. For Group II the relationship was examined by selecting rats with equivalent running and licking base rates, but whose running rates were eventually made to differ by manipulating wheel-torque requirements. Asymptotic reinforced instrumental responding was found to be linearly related to pre-contingent running base rates, for all FR schedules, and independent of the procedures used to obtain differing running base rates. The results support Premack's contention that asymptotic reinforced instrumental responding is a joint function of the reinforcing response and the operant level of the instrumental response.  相似文献

Previous findings indicate that natural category size affects cued recall but not recognition performance. Words that define or belong to larger categories are not as likely to be recalled in the presence of an extralist cue. However, category size has no effect on recognition in the presence of the target as the cue. Theoretically, this difference could be due to inherent differences between these tasks, to the use of different types of test cues, or to differences in the nature of the required responses (naming compared with “yes/no”decisions). Three experiments indicated that none of these factors is a sole determinant. Natural category size effects were found in cued-recall and recognition tasks, with extralist and target cues and regardless of the required response. The critical factor is whether the testing conditions require or encourage subjects to search the category defined by the cue. With the initiation of such a search, information represented in semantic memory is likely to influence memory for episodic information.  相似文献

Several programs have been written in the FOCAL, FORTRAN, and BASIC languages for reformatting and analyzing SKED data. These programs include selection and explicit labeling of sets of recording counters representing distributions and/or total counts of events, several general manipulations of distributional data, and standard statistical treatment of distributions.  相似文献

This case report describes an unusual combination of speech and language deficits secondary to bilateral infarctions in a 62-year-old woman. The patient was administered an extensive series of speech, language, and audiologic tests and was found to exhibit a fluent aphasia in which reading and writing were extremely well preserved in comparison to auditory comprehension and oral expression, and a severe auditory agnosia. In spite of her auditory processing deficits, the patient exhibited unexpected self-monitoring ability and the capacity to form acoustic images on visual tasks. The manner in which she corrected and attempted to correct her phonemic errors, while ignoring semantic errors, suggests that different mechanisms may underlie the monitoring of these errors.  相似文献

Children (75 female, 52 male) in grades 2 through 8 completed the Fear Survey Schedule for Children (FSS-FC). Their mothers completed the same questionnaire twice: once for themselves and a second time to estimate their children's fears. Spearman's rhos indicated that there was a high degree of correspondence between the mothers' rank-ordered estimates of their children's fears and the children's rank-ordered self-reports (=.86 for males, =.96 for females.However, mothers' overall estimates of their children's general fearfulness were significantly correlated only with their daughters' fearfulness, not with their sons'. Further analyses showed that mothers could generally identify their children's highest-rated fears. All test-retest measures were significant. In summary, these results suggest that mothers may provide useful clinical information about their children's specific fears and that the FSS-FC is a reliable instrument with which to assess children's fears.  相似文献
