In this paper we introduce certain constants that characterize exponential stability or exponential unstability of discrete linear time varying systems. We also present bounds for Lyapunov and Perron exponents in terms of the introduced constants. 相似文献

Executive functioning (EF) refers to higher order thought processes considered foundational for problem-solving. EF has both ‘cool’ cognitive and ‘hot’ emotional components. This study asks: (a) what are the relative contributions of ‘hot’ and ‘cool’ EF to children's academic achievement? (b) What are the relative contributions of ‘hot’ and ‘cool’ EF to learning-related classroom behaviors and observed engagement? (c) Do learning-related classroom behaviors and observed engagement account for the relation between EF and achievement? For a sample of 173 kindergarteners, cool EF predicted math achievement, learning-related classroom behaviors, and observed engagement. Hot EF did not predict any achievement or behavior outcomes when examined concurrently with cool EF. Children's classroom behavior did not account for the relation between cool EF and math achievement, suggesting cool EF and math performance are directly associated. 相似文献

在美国从殖民地走向独立的过程中,政治领袖们常常将教育视为国家进步的工具之一.学校和学院成为培养国家认同感和民族统一的理想场所,教育的"功用"与对国家繁荣、安全、和谐的追求紧密结合.美国革命初期,民族领袖们就教育与国家发展提出了一系列提议.其中,他们着重考虑了国立大学的提议--即建立一所确保美国立于世界开化国家之列的研究生教育机构.每一个关于国立大学的提案中都包含追求国家独立与清楚认识美国与欧洲的持续联系的深层矛盾.一些人认为欧洲能提供最好的高等教育机会,另一些人则警示国人有可能遭受来自海外的政治和学术"污染".因此.美国独立战争后主要的矛盾就在于留学海外的可知风险.本文认为,1780~1800年间,阻止未来的领导者留学海外的希望是推动美国高等教育发展的主要动力. 相似文献

Whereas a lot of studies examine cognitive processes in chess players, personality profiles of elite chess players are still not described well. The aim of this study was to examine personality of strong chess experts and its influence on chess skill. We tested elite male and female chess players with Freiburg Personality Inventory Revised (FPI-R), which also provides population norms for males and females. Elite male players' personality profile did not significantly differ from the population norms. Female players were more satisfied with life, had less physical complaints and higher achievement motivation in comparison with female population norms. Personality was also related with chess skill but showed different patterns in males and females. Stronger male players were more introverted, while we found the opposite pattern in female players. These results indicate that personality plays an important role in the highest level of complex intellectual activities. 相似文献

This article discusses regression effects that are commonly observed in Angoff ratings where panelists tend to think that hard items are easier than they are and easy items are more difficult than they are in comparison to estimated item difficulties. Analyses of data from two credentialing exams illustrate these regression effects and the persistence of these regression effects across rounds of standard setting, even after panelists have received feedback information and have been given the opportunity to discuss their ratings. Additional analyses show that there tended to be a relationship between the average item ratings provided by panelists and the standard deviations of those item ratings and that the relationship followed a quadratic form with peak variation in average item ratings found toward the middle of the item difficulty scale. The study concludes with discussion of these findings and what they may imply for future standard settings. 相似文献

An important consideration in standard setting is recruiting a group of panelists with different experiences and backgrounds to serve on the standard-setting panel. This study uses data from 14 different Angoff standard settings from a variety of medical imaging credentialing programs to examine whether people with different professional roles and test development experiences tended to recommend higher or lower cut scores or were more or less accurate in their standard-setting judgments. Results suggested that there were not any statistically significant differences for different types of panelists in terms of the cut scores they recommended or the accuracy of their judgments. Discussion of what these results may mean for panelist selection and recruitment is provided. 相似文献

This essay argues that within competitive sport zero-sum logic and the theory of mutualism are compatible and complementary. Drawing on Robert Simon’s theory of mutualism and Scott Kretchmar’s argument for zero-sum logic, this article shows how athletes can strive for a clear-cut victory and shared benefits such as athletic excellence fully and wholeheartedly at the same time. This paper will also consider how acknowledgment of this dynamic could advance understandings for ethical theories for sport. It will then conclude by describing a subjective approach that will make the affinity of zero-sum logic and mutualism more accessible for sports people. 相似文献
