Deterministic Chaos: Some Interesting Points of View from the Philosophy of Science. A comparatively simple example is used to present some of the main features of deterministic chaos. From the point of view of the philosophy of science, three questions are dealt with: if the equations of motion of chaotic systems are falsifiable in a strict sense; whether experiments on chaotic systems are reproducible; to what extent the development of chaotic systems is predictable. It emerges that in these respects chaotic systems, though being deterministic, behave essentially in the same way as stochastic (indeterministic) systems do.  相似文献

This paper provides a Genzten style formulation of the game logic framework GLm (0 m ), and proves the cut-elimination theorem for GLm. As its application, we prove the term existence theorem for GL used in Part I.  相似文献

The effect of informational feedback and graphing on reducing the number of arithmetic worksheet errors was investigated. The present study replicated and extended earlier findings with other populations (Journal of Applied Behavior Analysis, 1974, 7 , 547–555; 1970, 3 , 1–4; 1970, 3 , 235–240) to a first-grade classroom. Ten first-grade pupils (four males and six females) served in an ABAB design. During the feedback-only phase, subjects were provided informational feedback, in the form of a written number, on the number of errors made on individual arithmetic worksheets. The feedback-only phase lasted seven days and was followed by the feedback-plus-graphing phase, during which subjects graphed the number (of errors written at the top of the individual worksheet) daily on individual graphs on their desks. The feedback-plus-graphing phase lasted 10 days and was followed by a reversal to feedback only for 10 days. The final phase was a replication of the feedback-plus-graphing phase. All subjects showed a change in number of worksheet errors, in the predicted direction, during the feedback-plus-graphing phases. An overall mean difference of ?2.66 was found to be statistically significant (P < 0.01), using a Wilcoxson Matched-Pairs Sign Test. The results were interpreted as being empirical support for earlier findings in other populations. In addition, the present findings represented a successful extension of feedback and graphing interventions to the management of academic behaviors in a first-grade classroom.  相似文献

This study was designed to determine whether the asymmetry in children's acquisition of polar adjective pairs is based on linguistic factors related to differences in adult usage and frequency or on an underlying conceptual difference. 24 children, aged 3;7–4;11, took part in a concept-learning task in which nonsense syllables replaced English words for the positive and negative ends of four dimensions: size, height, length, and thickness. The data indicate that the syllables for the negative end of each dimension have a longer learning period and a greater prelearning error rate. These results support the hypothesis that the asymmetry observed in the acquisition of polar adjectives is based on an underlying conceptual asymmetry.  相似文献

This study was designed to investigate the development of knowledge about categorical and associative relationships as reflected by the presence or absence of semantic priming effects. Kindergarteners and second-graders were shown pairs of pictures, one picture at a time, and asked to name each picture as rapidly and accurately as possible. Picture pairs were of four types which reflected the factorial combination of associative relatedness (high and low) with categorial relatedness (high and low). An analysis of naming times revealed a significant main effect of associative relatedness, i.e., second pictures or “target” pictures in high-associative pairs were named faster than those in low-associative pairs. This reduction in naming latency, or priming effect, was independent of developmental level. However, the effects of category relatedness varied with developmental level, i.e., target pictures in high-categorical pairs were named significantly faster than those in low pairs by second-graders, but not by kindergarteners. These findings are discussed in terms of previous estimates of children's semantic competence.  相似文献

This study examined the effect of achievement goals and achievement emotions on sport satisfaction, performance and effort among competitive athletes. Participants were 200 athletes. Structural equation modeling was used to test the indirect effect of mastery-approach goals on satisfaction with sport experience and performance, the direct effect of mastery-approach goals on enjoyment and effort, the direct effect of performance-approach and performance-avoidance goals on performance, and the direct effect of mastery-avoidance goals on effort. Results showed a positive direct effect of mastery-approach goals on enjoyment and an indirect effect, through enjoyment, on satisfaction, performance, and effort. We did not find support for the hypothesized effect of performance-approach or performance-avoidance goals on performance. The applied implications of endorsing mastery-approach goals are discussed.  相似文献

春秋战国是汉字字体由篆到隶的重要时期,齐金文素以其精严整饬的美化藻饰体著称,但这只是其字体演变中的一个环节。齐金文字体演变在书写便捷的原动力下,通过体势趋扁趋方打破篆体长圆体势,通过短直的笔画分解篆体圆转的笔画,与其他地域的金文字体一起推动了汉字字体的演变,并以其鲜明的地域个性丰富了汉字字体面貌。  相似文献
