The direct methods of ratio estimation and magnitude estimation and the indirect method of pair comparison were used to construct scales of liberalism and conservatism. It was found ( a ) that the scales of conservatism are linearly related to each other and ( b ) those of liberalism are also linearly related to each other but with a discontinuity in the middle of the range; one linear function for the conservative statements and another for the liberal statements, with the discontinuity occurring in the middle of the subjective scale. Liberalism vs. conservatism was found to be reverse. The linear function between all kinds of scales as well as the reverse relation between liberalism vs. conservatism suggest that the continuum of political preferences is metathetic. 相似文献

In this paper a method is outlined for measuring the diversity of the results of applied R&D with the use of IPC (International
Patent Classification). The method has been tested in the contexts of the academic physical, engineering, and chemical institutes.
The trend of applied research at a given institute increases both at the level of classes and subclasses, and at the IPC level.
Inventions developed within specializations at each institute have a greater efficiency than other forms of inventive activity.
The objective was to seek the optimal extent of diversification of applied R&D, which would simultaneously ensure the preservation
of the scientific specialization of an institute, the high level of scientific research associated with developing innovations,
and the high overall efficiency of each institute. 相似文献

Finland has followed the Scandinavian model of the welfare state in which the level of state activism is high, the economic
pressures on the scientific activities are strong, and the left-wing parties and the Center Party have formulated the main
ideas. In the 1970s welfare ideology was adopted in science policy by emphasizing the promotion of socially relevant scientific
activities and the expansion of the university system as a means of effecting equal opportunity. Currently, the trend is toward
a mixed welfare economy. Programs have been prepared in spite of the radical cut in government expenditure, and without a
consideration of the long-term consequences. 相似文献

When an observer views a moving scene binocularly, both motion parallax and binocular disparity provide depth information. In Experiments lA-1C, we measured sensitivity to surface curvature when these depth cues were available either individually or simultaneously. When the depth cues yielded comparable sensitivity to surface curvature, we found that curvature detection was easier with the cues present simultaneously, rather than individually. For 2 of the 6 subjects, this effect was stronger when the component of frontal translation of the surface was vertical, rather than horizontal. No such anisotropy was found for the 4 other subjects. If a moving object is observed binocularly, the patterns of optic flow are different on the left and right retinae. We have suggested elsewhere (Cornilleau-Pérès & Droulez, in press) that this motion disparity might be used as avisual cue for the perception of a 3-D structure. Our model consisted in deriving binocular disparity from the left and right distributions of vertical velocities, rather than from luminous intensities, as has been done in classical studies on stereoscopic vision. The model led to some predictions concerning the detection of surface curvature from motion disparity in the presence or absence of intensity-based disparity (classically termedbinocular disparity). In a second set of experiments, we attempted to test these predictions, and we failed to validate our theoretical scheme from a physiological point of view. 相似文献

Paradigmatic complexes in family psychotherapy have been indicating a revolutionary change and the creation of new paradigms for the past thirty years. Starting with the application of the general systems theory and the development of those concepts that have been emerging regarding psychosomatic illnesses we discuss the epistemological confusion created, the methodological problems and the dissociation between theory and practice. We suggest a double process of investigation of the family structure using a knowledge of the basic attitudes and the development of a psychotherapy programme within the family of the psychosomatic patient. 相似文献

Tested a 7-month, media-based, community intervention among Hispanics in San Francisco designed to change levels of information on the damaging effects of cigarette smoking and on the availability of culturally appropriate cessation services. Three community-wide surveys of Hispanics were conducted with independent random samples, two as baselines (n = 1,660 and 2,053) and one postintervention (n = 1,965). Results showed that changes in the level of awareness of cessation services had taken place after implementation of the intervention. Furthermore, those changes took place primarily among the less acculturated Spanish-speaking Hispanics who were the target of the intervention. The changes in information reported here demonstrate that a culturally appropriate information dissemination campaign that utilizes multiple channels can produce changes in a community's level of information even when the campaign is implemented for a relatively short period. 相似文献

Earlier research has shown that extraverts tend to increase their visual evoked potential amplitudes with increasing light intensity (augmenting), while introverts reach their maximum amplitude at lower intensities (reducing). The evoked response has normally been measured from association areas of the brain (at the vertex). The present study measured VEP amplitudes over visual cortex and at the vertex, using four light intensities in two conditions, where attention was either directed towards the light stimuli, or away from them by a concurrent auditory task. Forty subjects were classified as extraverts or introverts based on the Eysenck Personality Inventory. The results show that attention interacted significantly with extraversion. Introverts exhibited a narrower focus of attention, while higher amplitudes and amplitude-intensity functions when attending to the light flashes and lower when distracted. Extraverts showed smaller differences between conditions, indicating a more evenly distributed attention. Higher arousal in introverts is the probable cause of their narrower focus of attention. There were marked differences in the distribution of activity between vertex and occipital cortex. Introverts showed relatively stronger occipital responses and extraverts stronger vertex responses across all intensities and in both conditions. The predisposition for mainly perceptual responses to aversive stimuli in introverts, and for general alerting and motor preparatory responses in extraverts, are interpreted as supportive of Brebner and Cooper's hypothesis that introverts are ‘geared to inspect’ and extraverts are ‘geared to respond’. 相似文献

Recently, several studies have addressed the question of whether depression affects priming in implicit memory tasks. The main aim of this experiment was to assess the presence of a bias for negative information in explicit memory (free recall) and implicit memory (word-stem completion) tasks among subclinically depressed subjects compared to nondepressed subjects, using the typical levels of processing manipulation. The results of this study show the existence of a mood-congruent memory bias for both implicit and explicit memory in depressed subjects. The theoretical implications of these findings for implicit and explicit memory biases associated with depressed mood are discussed. 相似文献

The relational communication of sixteen dropout versus sixteen continuation sessions of solution-focused therapy was studied using two different coding schemes. On the Topic Initiation/Topic Following coding scheme (Tracey, 1986) no differences were found between dropout and continuation sessions, whereas the Family-Relational Communication Control Coding Scheme (Heatherington and Friedlander, 1987) yielded a number of significant findings. Both in 'successful' and in 'unsuccessful' dropout sessions, therapeutic interaction was found to be more conflictive than in continuation cases, with clients showing more domineering behaviour in dropout than in continuation sessions. Markovian and lag sequential analysis are used to clarify some of these findings, and their implications are discussed. 相似文献

In this review, we consider three possible criteria by which knowledge might be regarded as implicit or inaccessible: It might be implicit only in the sense that it is difficult to articulate freely, or it might be implicit according to either an objective threshold or a subjective threshold. We evaluate evidence for these criteria in relation to artificial grammar learning, the control of complex systems, and sequence learning, respectively. We argue that the convincing evidence is not yet in, but construing the implicit nature of implicit learning in terms of a subjective threshold is most likely to prove fruitful for future research. Furthermore, the subjective threshold criterion may demarcate qualitatively different types of knowledge. We argue that (1) implicit, rather than explicit, knowledge is often relatively inflexible in transfer to different domains, (2) implicit, rather than explicit, learning occurs when attention is focused on specific items and not underlying rules, and (3) implicit learning and the resulting knowledge are often relatively robust. 相似文献
