《红楼梦》中的强本节用动因有三:第一就是空架子,理省俭,须运筹谋画,建立进货环节的验收制度和付款环节的监控体系。第二就是破荷叶、草根子,应综合利用,树立开源节流的财务管理理念,探讨经营承包机制的建立。第三,登利禄,处运筹,通尧舜孔孟,提出强本之策和节用之计。在强本节用措施上分三步走:一是定人选,选项目,搞责任承包;二是辟财路,找措施,须深挖细掘;三是既遵制,又创新,共建和谐园区。  相似文献

如果f"(x)>0(a<x<b),则曲线y=f(x)[a,b]上,[1]说是凸的,[2]说是凹的,教辅书[3]说是下凸的,因此,导致三难,用起来很不方便.在拜读了叶彦谦老先生译《微积分学教程》(人民教育出版社1956年新1版)后,并思索看图习惯,函数的凸凹性应是:  相似文献

It is a widely held belief that anchor tests should be miniature versions (i.e., minitests), with respect to content and statistical characteristics, of the tests being equated. This article examines the foundations for this belief regarding statistical characteristics. It examines the requirement of statistical representativeness of anchor tests that are content representative. The equating performance of several types of anchor tests, including those having statistical characteristics that differ from those of the tests being equated, is examined through several simulation studies and a real data example. Anchor tests with a spread of item difficulties less than that of a total test seem to perform as well as a minitest with respect to equating bias and equating standard error. Hence, the results demonstrate that requiring an anchor test to mimic the statistical characteristics of the total test may be too restrictive and need not be optimal. As a side benefit, this article also provides a comparison of the equating performance of post-stratification equating and chain equipercentile equating.  相似文献

The paper uses the Integrated Postsecondary Education Data system (IPEDS) data to simulate the 2020 American Graduation Initiative (AGI) goal introduced by President Obama in the summer of 2009. We estimate community college graduation rates and completion numbers under different scenarios that include the following sets of variables: (a) internal education variables; (b) external workforce development variables; and (c) state and national environmental factors. Our analysis suggests that the likelihood of success of meeting the AGI goal increases dramatically if community colleges are able to raise graduation rates and increase completion numbers by doing the following: (a) lowering the inherent risk factors that prevent students from graduating by implementing proactive retention and completion strategies; (b) operating in economic and workforce development environments of low unemployment levels and (c) taking into consideration the ever-growing globally competitive environment.  相似文献

ABSTRACT

The majority of deaf and hard of hearing (DHH) students are educated at least part of the day in general education classrooms taught by teachers who may not have any experience working with this population. DHH students make up a unique, heterogeneous group with a wide range of communication modalities, technology utilization, early intervention experiences, and educational placements. In addition to providing direct service to support these students, teachers of students who are deaf or hard of hearing (ToDHH) collaborate and consult with classroom teachers and school staff on classroom accommodations and modifications. However, recent research shows that ToDHH often feel unprepared to engage in the consultative aspect of their role. Since the Education for All Handicapped Children Act was passed 43 years ago, the field of deaf education has increasingly called for research on consultation models to apply to their unique population and to teach in their teacher preparation programs. This article identifies the characteristics of DHH learners and synthesizes current research on consultation in the field of deaf education. Three consultation models are examined to determine their level of fit within the field of deaf education. The author ends with a call for future research that can best be met through an interdisciplinary research approach between the field of deaf education and the fields of educational and psychological consultation.  相似文献

现行司法体系中存在的行政化、地方化、低职业化等现象要求进行司法体制改革,而法检省级统管是司法体制改革的基层探索,是最终实现顶层设计的必要步骤。法检省级统管首先必须以司法体制独立、司法体系完整和司法权衡制约为实现司法公正价值的形式目标,并从主体和配套机制两方面出发完善司法体制,设立审判委员会,推行拟垂直模式,并行监督机制以构建省级统管制度。同时,严防法检省级统管中出现的制度风险,最终从价值目标和制度设计上探索司法体制改革省级统管制度。  相似文献

略论清政府经营轮船招商局的成败   总被引:1,自引:0,他引:1  
近代中国的航运业是被迫开放的最早行业之一,也正是在这个行业,清政府比较成功地利用了资本主义国家资本输出在客观上提供的有利条件,借鉴了先进的生产工具和经营管理方式,创办了中国第一个民用企业轮船招商局,招商局从成立伊始就是为外资航运业的对立面出现的,在洋务派的扶持和保护下,轮船招商局采取切可行的措施,努力扩充自己的力量,积极参与国际竞争,并取得了一定的成绩。但封建的清政府终究不能使它在竞争取得彻底的胜利。  相似文献

The characterization of complexes is particularly critical for quality control and development of gene delivery systems. Here, the method of capillary zone electrophoresis (CZE) for the characterization of DNA and poly-L-lysine (MW 28 500) or DNA and poly-L-lysine modified with polyethylene glycol (MW10000) complexes at various charge ratios in phos-phate buffer is described firstly. During the characterization, DNA complexes can be separated into various components with different charge-to-mass ratio, i.e, components with single physicochemical property. And also the size and zeta potential of complexes were characterized by using photon correlation spectroscopy. This method is useful to characterize various com-plexes formed by DNA and polycations, and has the potential to separate complexes into homogeneous component for better transfection efficiency in vitro and in vivo in future.  相似文献

宋代理学的重要支派--心学派是以"存心、养心、求放心"为其核心思想的.在此基础上,该派提出了独特的"天籁自鸣"说,其主要观点是天籁自鸣之境界的前提是作者须依据本心,心无邪思;天籁自鸣之境界产生的基础是物我一体;天籁自鸣之境界的根本特色是与雕琢造作相对应的天成自然.  相似文献
