图的L(s,t)-标号的概念来自频道分配问题.设s和t是2个非负整数.图G的一个L(s,t)-标号是一个从G的顶点集到整数集的映射,满足:①任意2个相邻顶点对应的整数相差至少为s;②任意2个距离为2的顶点对应的整数相差至少为t.给定图G的一个L(s,t)-标号f,的L(s,t)边跨度定义为max{|f(u)-f(v)|:(u,v)∈E(G)},记为βst(G,f).图G的L(s,t)边跨度定义为min{βst(G,f):f取遍图G的所有L(s,t)-标号},记为βst(G).设T是一棵最大度为△(≥2)的树.证明了:若2s≥t≥0,则βst(T)=([△/2]-1)t s;若0≤2s<t且△为偶数,则βst(T)=[(△-1)t/2];若0≤2s<t且△为奇数,则βst(T)=(△-1)t/2 s.同时完全确定了2条路的笛卡儿乘积图和正四边形格图的L(s,t)边跨度.  相似文献

This article examines challenges in writing histories of feminist reforms in schooling and educational administration. The focus is gender equity reforms in Australian schools since the 1970s, looking at how those earlier interventions are now remembered, represented and forgotten, in policy memory and collective narratives. Such feminist endeavours were part of the policy landscape and the administration of schools during the 1970s and 80s. I argue that feminist agendas can also be examined as themselves sites for managing the conduct of teachers and students and for regulating new forms of identity and social relations. These paradoxical aspects of feminist reform are analysed through a Foucauldian lens. The discussion identifies contextual themes in JEAH before considering debates within gender and feminist history. A revisiting mood has initiated a stocktake of the stories told not only about feminism but also the accounts feminism gives of itself. Extending this, I propose that critical attention to memory and the movement of received and revised historical narratives is vital for analysing the legacies of feminist reforms and how they might be (re)animated in the present. More broadly, it is suggested that attention to policy memory offers fruitful directions for historical studies of educational administration.  相似文献

对于给定图G顶点集上一个非负整数函数f,满足:若dG(u,v)=1,f(u)-f(v)≥d;若 dG(u,v)=2,f(u)-f(v)≥1.称f 为L(2,1)-标号.这是由频道分配问题抽象出来的数学模型.本文主要研究该标号问题的一个参数,即边跨度,记作βd(G)=minf max{f(u)-f(v):u∈V(G)},即对于所有正常的L(d,1)-标号,使得相邻顶点标号之差的最大值达到最小.本文主要讨论了圈Cn、树T、 k-部完全图、正三角形网格、 正四边形网格以及弦图等图类的边跨度,并给出了确切的数值.  相似文献

Students with or without expertise in the domain of investments were tested on recall of a list of words containing both investment terms and other terms not related to the domain of investment. Consistent with predictions derived from the expert memory literature, the memory illusion literature, and the ascribed characteristics of implicit associative responses, experts recalled more investment-related words and, paradoxically, also made more false recalls in that domain. This pattern of results paralleled the pattern of differences between another sample of experts and novices in strength of word associations in the two domains.  相似文献

Mayer多媒体学习的认知理论模型涉及感觉记忆、工作记忆、长时记忆三大基本部件和五大认知加工过程,但其科学基础仍有待深入考察。认知神经科学对感觉记忆、工作记忆和长时记忆的探索成果为多媒体学习认知理论奠定了更为深层的科学基础。认知神经科学认为,感觉记忆中的视觉记忆和声觉记忆在信息存储量、表征与编码、保持时间等方面存在互补,为多媒体学习认知理论中"双重通道假设"提供了更深层次的科学基础。工作记忆是多媒体学习认知加工过程的主要处理单元,认知神经科学基于脑成像技术提出的工作记忆加工成分结构及其功能定位模型和语音短时记忆功能模型,揭示了工作记忆中的信息处理机制,进一步推进了对工作记忆的基础研究。认知神经科学将长时记忆分为陈述性记忆和程序性记忆,长时记忆中信息存储的层次网络模型、激活扩散模型、集理论模型等更深入地推进了多媒体学习认知加工过程的科学基础。德国心理学家Schnotz从描述性表征和描绘性表征两个方面提出了多媒体学习"图文理解整合模型"(ITPC),这一模型揭示了图文理解的过程机制,是当前多媒体学习认知理论模型的最新发展成果。  相似文献

This study analyzes the influence of Michael Moore's Fahrenheit 9/11 in coordination with presidential debate viewing on the outcome variable of confidence in George W. Bush's policy positions. In addition, the combined influence of these competing persuasive appeals is assessed across three political ideology groups: liberals, moderates, and conservatives. There is a statistically significant experimental stimulus-by-political ideology interaction, with Bush making substantial gains among political moderates who viewed Moore's film prior to a Bush-Kerry debate. The study also reveals similar patterns of influence for liberals and conservatives.  相似文献

What sorts of images and narratives of cosmopolitanism are circulating in our cultural discourse? Stories and ideas based on experiences of migration, travel, and exile are considered in relation to the Italian city of Naples, to propose an example of “South-centric” cosmopolitanism. Two different journeys in the Mediterranean, as narrated by Moroccan writer Tahar Ben Jelloun and by Neapolitan film director Vincenzo Marra, engage with the experience of travel through stories that in opposite directions—the first from North Africa to Naples, and the second from Naples to North Africa—cross territories and lines of logic of Northern and Southern boundaries and deal with notions of belonging and homecoming.  相似文献
