This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single
sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction works
out the unsolved problem pointed out by Hansson in [Han99, pp. 369].

Abstract : "North‐South" divides usually overlook the fact that Latin America was also part of the New World. It was only after WW II that these countries were lumped together in a large bunch called "third world." For the sake of simplicity, this paper restricts itself to the period when Liberation Theology made its appearance until now. Even though the seventies devised an autonomous Christianity, with its own traits and purposes, nowadays the churches are back in the mainstream. Issues that engage Christians there are not unlike their counterparts in "the North," thanks to globalization. Demographic changes are still more important than cultural ones, and economic prospects are more likely to interfere in the shape of Christianity than the will and emotions of leaders and the faithful alike. 相似文献

The primary aim was to explore and compare the dimensionality of personal epistemology with respect to climate change across
the contexts of Norwegian and Spanish students. A second aim was to examine relationships between topic-specific epistemic
beliefs and the variables of gender, topic knowledge, and topic interest in the two contexts. Participants were 225 Norwegian
and 217 Spanish undergraduates enrolled in psychology or education courses, and the dimensionality of topic-specific personal
epistemology was explored through factor analyses of the scores on a 49-item questionnaire. Hierarchical multiple regression
analyses were used to predict scores on the epistemic belief dimensions emerging from the factor analyses with gender, topic
knowledge, and topic interest, respectively. Even though considerable cross-cultural generalizability in dimensionality was
demonstrated, this research also draws attention to the cultural embeddedness of topic-specific epistemic beliefs. Moreover,
differences in the predictability of topic knowledge and topic interest in Norway and Spain, suggest that factors constraining
or enhancing adaptive epistemic beliefs concerning particular topics may vary across cultures. 相似文献

When a stimulus appears in a previously cued location several hundred milliseconds after the cue, the time required to detect that stimulus is greater than when it appears in an uncued location. This increase in detection time is known as inhibition of return (IOR). It has been suggested that IOR reflects the action of a general attentional mechanism that prevents attention from returning to previously explored loci. At the same time, the robustness of IOR has been recently disputed, given several failures to obtain the effect in tasks requiring discrimination rather than detection. In a series of eight experiments, we evaluated the differences between detection and discrimination tasks with regard to IOR. We found that IOR was consistently obtained with both tasks, although the temporal parameters required to observe IOR were different in detection and discrimination tasks. In our detection task, the effect appeared after a 400-msec delay between cue and target, and was still present after 1,300 msec. In our discrimination task, the effect appeared later and disappeared sooner. The implications of these data for theoretical accounts of IOR are discussed. 相似文献

Thirty-two male and thirty-two female high school counselors in a large metropolitan school district were provided with routine student profile data and asked to make predictions about the student's potential for post-high school education and to suggest occupations for the student to explore. All data reviewed by the counselors were identical except for a photograph of the student attached to the profile. Within counselor sex groups, counselors were randomly assigned to one of the following four photograph conditions: (a) attractive female; (b) unattractive female; (c) attractive male; and (d) unattractive male. Male subjects were found to discriminate on the basis of student sex when they suggested occupations for the student to explore. Predictions of post-high school education and the social status of suggested occupations were not found to be related to counselor sex, student sex, or student attractiveness. 相似文献

Memory for action events in the bottlenosed dolphin 总被引:2,自引:0,他引:2
We investigated whether a bottlenosed dolphin’s ability to recall and repeat actions on command would immediately generalize
to actions performed with specified objects. The dolphin was tested on her ability to repeat 18 novel behaviors performed
with potentially interchangeable objects specified using an artificial gestural language. Such “action events” were correctly
repeated at above chance levels, indicating that the dolphin had access to memories of those events. Performance levels were,
however, lower than in previous tests. The dolphin appeared to have difficulty recalling which object an action was performed
with. Previous research has demonstrated that animals can recall features of their environment and features of their actions
independently of one another. The results of this study demonstrate (1) that the dolphin’s concept of repeating extends beyond
simply accessing memories of movement patterns, and (2) that dolphins’ memories of past events incorporate representations
of both self-performed acts and objects, locations, or gestural instructions.

The present work is part of a decade-long study on the spontaneous use of stones for cracking hard-shelled nuts by a semi-free-ranging group of brown capuchin monkeys (Cebus apella). Nutcracking events are frequently watched by other individuals--usually younger, less proficient, and that are well tolerated to the point of some scrounging being allowed by the nutcracker. Here we report findings showing that the choice of observational targets is an active, non-random process, and that observers seem to have some understanding of the relative proficiency of their group mates, preferentially watching the more skilled nutcrackers, which enhances not only scrounging payoffs, but also social learning opportunities. 相似文献

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4–5 years old children's motor development (both fine and gross motor skills), and its relation to language and mathematical development. A total of 219 Colombian Caribbean children (105 boys and 114 girls) aged 4 and 5 years participated in this study. Results revealed higher motor skills among girls, although differences by gender were not notable. Positive and significant correlations were found between motor skills and language and mathematical skills, although most of the correlations were weak or moderate. Also, it was observed that fine motor skills were less related to language or mathematical development in comparison with gross motor skills, especially among boys. These results suggest that among Colombian Caribbean children gross motor skills could have a higher influence on the development and acquisition of some language and mathematical skills in comparison with fine motor skills. 相似文献
