Abstract The ability of amorphous metallic alloys to resist irradiation-induced structural changes will depend on the composition of the alloy and the particle fluences used. In this paper we show that a fast neutron fluence of 1020 cm?2 can induce local crystallization in a refractory NiTi glass. For specimens irradiated with lower fluences, the mode of crystallization of the amorphous matrix is changed from that of a primary process to a eutectic mechanism. 相似文献

This paper provides an overview of an interdisciplinary programme of research started more than 20 years ago at the University of Tokyo. A major aim of this programme was (and still is) to develop methods and related forms of quantitative analysis that provide rigorous evaluations of infant behaviour from a particular theoretical perspective. In one part of the programme telethermography is used to measure emotional changes in young infants. Contrary to the accepted view in attachment theory, infants as young as 2–3 months showed evidence of stress following separation from the mother (as indexed by a drop in the skin temperature of the infant's forehead). In another part, we established the presence of interpersonal synchrony between arm movements of the newborn and the speech of the mother and other adults, using computer assisted pattern recognition techniques. On the basis of this finding, we have proposed a simulation model of mother-infant interaction from the perspective of system information theory. In general, our programme of research provides a theoretically driven set of techniques and analytical approaches that may provide deeper insights into early development and parenting. 相似文献

In his commentary, Heine has done a thorough job of reviewing research on self–enhancement biases in Japan. Insofar as he conducted much of the work he reviewed, we assume he has characterized the findings fairly and accurately and see no need to comment further upon them. Instead, we will take this opportunity to discuss the nature of self–enhancement more generally, including its affective basis and its manifestation in different cultural contexts. In so doing, we hope to clarify the manner in which Japanese satisfy their self–enhancement needs. 相似文献

The present study explores to what extent Asian elephants show “means–end” behavior. We used captive Asian elephants (N = 2) to conduct four variations of the Piagetian “support” problem, which involves a goal object that is out of reach, but
rests on a support within reach. In the first condition, elephants were simultaneously presented with two identical trays
serving as the “support”, with the bait on one tray and the other tray left empty. In the next two conditions, the bait was
placed on one tray, while additional bait was placed beside the other tray. In the last condition, both trays contained bait,
but one of the trays had a small gap which prevented the elephants from reaching the reward. Subjects were required to choose
and pull either tray with their trunk and to obtain the bait (i.e. goal). Results showed that one elephant performed all of
the support problems significantly above chance after several sessions, suggesting that the elephant was capable of understanding
that pulling the tray was the “means” for achieving the “end” of obtaining the bait. This study showed that elephants show
means–end behavior when subjected to a Piagetian “support” task, and indicates that such goal-directed behavior occurs in
species other than primates. 相似文献

This study investigated whether Asian elephants can make relative quantity judgment (RQJ), a dichotomous judgment of unequal
quantities ordered in magnitude. In Experiment 1, elephants were simultaneously shown two baskets with differing quantities
of bait (up to 6 items). In Experiment 2, elephants were sequentially presented with baits, which could not be seen by elephants
in their total quantities. The task of elephants was to choose the larger quantity in both experiments. Results showed that
the elephants chose the larger quantity with significantly greater frequency. Interestingly, the elephants did not exhibit
disparity or magnitude effects, in which performance declines with a smaller difference between quantities in a two-choice
task, or the total quantity increases, respectively. These findings appear to be inconsistent with the previous reports of
RQJ in other animals, suggesting that elephants may be using a different mechanism to compare and represent quantities than
previously suggested for other species. 相似文献

Although evidence abounds in American criminology that young males are more prone to deviance than females, relatively little is known about the magnitude of the gender gap in deviance across cultures. Drawing on the literature concerning “risk taking” in power-control theory and on theory and research concerning cultural variability in “uncertainty avoidance,” we offer a rationale for predicting that the gender differences in levels of deviance are less among Japanese youth than Americans. Among Japanese, the level of male deviance should be closer to that of females because “uncertainty avoidance” is a strong component of Japanese culture that affects socialization of both males and females. Analysis of identical survey data from college students in Japan and the United States provides strong support for our argument. 相似文献

The present study examined the effect of intertextual conflict resolution on learning from conflicting texts. In two experiments, participants read sets of two texts under the condition of being encouraged either to resolve a conflict between the texts' arguments (the resolution condition) or to comprehend the arguments (the comprehension condition). Experiment 1 found that participants in the resolution condition surpassed participants in the comprehension condition at the understanding of the controversial subjects and succeeded in the understanding of the intertextual relationships. Experiment 2 found that participants in the resolution condition recalled compatible and incompatible information from the texts more than did participants in the comprehension condition. The recalled information from one text was also positively correlated with that from the opposite text. These results suggest that intertextual conflict resolution facilitates successful integration of conflicting arguments in texts in terms of the documents model framework (e.g., Britt & Rouet, 2012). 相似文献
