Criteria families use to select nursing homes

The study is conducted to determine families' rankings of characteristics they consider most important when selecting a nursing home. Friedman's two-way analysis of variance is used to test for differences in the rankings. In response to a mailed survey, 231 families rank the characteristics in the following order: quality of care, appearance, atmosphere, location, reputation, building safety, quality of food, cost, and activities. Relationships are also found between the rankings and the demographic characteristics: gender, marital status, education, income, number of homes available, patient/respondent relationship, and distance respondent lived from the chosen home.     

想象力与古典诗词教学--古代文学教学与创新思维培养研究论文之三

想象力是发展创新思维的翅膀。古代文学教学,应当充分利用古典诗词所具有的想象空间,从引导学生储备丰富的记忆表象、培养敏锐的理解领悟力、激发创造性的形象思维力和拓展多样的情感空间等方面入手,在赏析作品的过程中培育学生的想象力,将知识的传授与能力的培养紧密结合起来。     

长期雇佣、异质型人力资本与企业核心竞争力

长期雇佣是异质型人力资本形成的前提,异质型人力资本是构建企业核心竞争力的源泉。由于异质型人力资本具有非竞争性、难以模仿性、价值性、稀缺性等特点,以及异质型人力资本与企业核心竞争力之间存在着路径依赖性、社会复杂性、因果关系模糊性,导致企业形成内化和差异化的核心竞争力,最终形成持久、稳定的竞争优势。长期雇佣、异质型人力资本与企业核心竞争力的契合、匹配,受许多因素的制约和影响。

Learning from Japanese Experience in Aged Care Policy

Like Singapore, Japan is projected to age rapidly. Japan is the first country in the world where more than 20% of the total population is over 65. Even as Japan adapts from western Europe and America where population ageing is more advanced up till now, it has been pioneering its own aged care policy, given the differences in sociocultural and political contexts. Of particular interest is its introduction of long-term care insurance and its effectiveness in meeting the needs of the long-term care of the aged and their family caregivers. In this article I seek to compare and contrast Singapore and Japan in terms of their demographic changes leading to rapid ageing, and their respective policy and program responses to a rapidly ageing population, drawing lessons from the Japanese experience.     

How can we Define the Concept of Long Memory? An Econometric Survey

In this paper we discuss different aspects of long memory behavior and applicable parametric models. We discuss the confusion that can arise when the empirical autocorrelation function decreases in a hyperbolic way.     

建筑的道德记忆承载功能

作为一种实用艺术,建筑能够通过建筑空间与相关主体自身背景的共鸣,给予相关主体丰富而深刻的艺术审美感受。在建筑审美中,个人的道德记忆起到了重要作用。建筑承载的道德记忆最初来自于特定个体,但通过时间的积累沉淀,它最终会提升为一种集体道德记忆。建筑具有传承性特征,并且具有传承道德记忆的能力。人类的建筑审美活动高度依赖其自身的建筑道德记忆,承载道德记忆的建筑大都具有历史和道德教育作用。从道德记忆理论的视角来看,现代建筑使建筑本身承载人类道德记忆的功能被严重弱化,甚至对建筑的道德记忆承载功能起着严重的破坏作用。当代建筑师既应该向人类的建筑道德记忆学习,也应该给子孙后代留下有价值的建筑道德记忆。     

言语领域内隐认知研究述评

内隐认知在言语“习得”中不仅具有存在性、普遍性 ,而且同外显认知一样还具有功能上的相对独立性 ;外显认知和内隐认知在认知中相互协同 ,在一定条件下它们可以相互转化
