多分销中心供应链模型及其牛鞭效应的H∞控制

本文在文^[1]具有一个分销中心供应链模型的基础上,建立了具有多个分销中心的供应链结构模型,采用供应链上游库存与订货偏差波动之和与下游顾客需求偏差波动之比描述牛鞭效应。提出顾客末端需求波动最差条件下H_∞控制方法,以抑制牛鞭效应。这一方法本质就是供应链末端需求波动最差情况下,制定供应链管理的最优决策。并且以一个石油分销系统为对象进行了供应链牛鞭效应的H_∞控制仿真实验。

绘本游戏阅读活动开展的意义及其指导策略

游戏式阅读活动旨在充分发挥绘本中的游戏精神和教育价值,让幼儿在获得充分的游戏体验的同时,促进其各种能力的发展。教师在游戏式阅读活动中指导的关键在于能否正确看待绘本中的游戏精神与教育价值,满足幼儿“阅读游戏”的体验,把握“游戏式阅读”的指导要点,避免陷入重知识传授、轻游戏体验的教学误区。     

边疆民族地区小学教师校本培训评估

借鉴柯氏四级评估法的评价指标,运用问卷调查法和访谈法实地调研了边疆民族地区小学教师及学校管理者,从参训教师及学校管理者的不同视角对校本培训的反应层、学习层、行为层、结果层四个层级来评价培训的实施成效。评估结果显示,边疆民族地区小学教师校本培训的改进方向是确定教师培训需求、优化培训内容以及维持受训教师行为水平。     

From victims to winners: strategies of negotiation among relocated residents in demolition-compensation events in local China

It has been well documented by researchers that in China’s continual quest for modernisation and urbanisation, many urban and rural residents became displaced and portrayed as victims. A more important question however needs to be explored: do evicted residents learn from others to develop strategies to protect themselves from becoming victims? Through in-depth interviews, primary data collection, documentary research, this study has confirmed that for some evicted residents in Southern China’s urban fringes, when their land was appropriated by local government and developers and they were offered resettlement elsewhere, they did not behave passively to accept the terms of compensation dictated. Instead, they actively learnt from other dwellers who were evicted earlier to become well-organised, resourceful, and sophisticated negotiators in bargaining for their compensation. The group of rural residents proved that they could do better than the evicted urban residents, especially in terms of compensation-negotiation.     

汉语古诗词中缺省现象的认知解读和翻译策略

汉语古诗词往往通过设置空白激发丰富的言外之意。从认知的角度看,这些空白是诗人考虑到与读者共享一些知识而留在文中的缺省信息,也是读者在阅读过程中所激活的认知结构的空位,他们必须调用认知结构的默认信息(包括框架的默认值、脚本的隐含序列、隐含的隐喻源域或目标域、隐含的转喻次域或主域)填补空白才能获取其中的言外之意。在翻译过程中,译者须考虑到译入语读者的认知知识和文化传播的目的,采取明示或保留缺省信息的翻译方法,也就是认知默认值的显译或隐译策略。

Asymptotic relative efficiency of the linear discriminant function under partial nonrandom classification of the training data

This paper considers the problem where the linear discriminant rule is formed from training data that are only partially classified with respect to the two groups of origin. A further complication is that the data of unknown origin do not constitute an observed random sample from a mixture of the two under- lying groups. Under the assumption of a homoscedastic normal model, the overall error rate of the sample linear discriminant rule formed by maximum likelihood from the partially classified training data is derived up to and including terms of the first order in the case of univariate feature data. This first- order expansion of the sample rule so formed is used to define its asymptotic efficiency relative to the rule formed from a completely classified random training set and also to the rule formed from a completely unclassified random set.
