英语事序及其基本表达方式     

顾立志 《华侨大学学报(哲学社会科学版)》2005,(3):121-127

事序是英语的重要语言现象。事序深刻地反映一事物与他事物之间的关系，表达语篇内的命题或交际行为的句子之间的语义连贯，确切地体现作者的思想。笔者探讨了英语事序的内涵、结构要素和属性，研究了事序表达的基本方法，并归纳了事序的五个基本特点。  相似文献

国有股表决权证券化推进经济民主与政治民主     

郭洪涛 《阿坝师范高等专科学校学报》2003,(4):28-31

当前应将上市公司的国有股表决权证券化为类似于股票的国有股表决权证,并在沪深股市竞价发行后流通交易,将上市公司控制权由国家转给股民,制定《国有股被动表决权法》,政府依法管理国有股与行使上市公司政治控制权,实现政企、政经合理分开,扩大国民的经济决策参与权,使国有经济决策实现民主化与法制化,以经济民主推动政治体制改革与经济体制改革协调发展。  相似文献   

Models and Paradigms in Kuhn and Halloun     

Paul Joseph Wendel 《Science & Education》2008,17(1):131-141

In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper, I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking to another and an easy back-and-forth switch between paradigms. Since Kuhn’s paradigms are self-enclosed and incommensurable, there is no objective standard by which one paradigm can be shown to be superior to the other. But Halloun uses ‘viability’ as a standard for paradigm choice. Underlying all of this is the more basic question of whether the history of science is an appropriate metaphor for student progress in the classroom. I conclude with some brief thoughts on this question.  相似文献   

论唐宋诗词的时空结构形态   总被引：1，自引：0，他引：1  

张红运 《信阳师范学院学报(哲学社会科学版)》2002,22(2):70-74

时间和空间是一切事物同时也是古典诗词得以存在的基本形式。由此出发，章将唐宋诗词里利用时间和空间关系构章谋篇的样式归纳为三种，即时空平行、时空错综、时空隐喻；这不失为进一步透析古诗词章法意境的一个角度。  相似文献   

An efficient method for tracing planar implicit curves   总被引：1，自引：0，他引：1  

YU Zheng-sheng CAI Yao-zhi OH Min-jae KIM Tae-wan PENG Qun-sheng 《浙江大学学报(A卷英文版)》2006,7(7):1115-1123

INTRODUCTION Tracing a planar implicit curve f(x, y)=0 on a rectangular region [xl, xr]×[yb, yt] is of great interest in Computer-Aided Design and Computer Graphics. While parametric curves are easy to plot, plotting implicit curves is a challenging problem. Planar im- plicit curve plotting method can be classified into two categories (Shou et al., 2005; Martin et al., 2002; Lopes et al., 2002). In the first category are subdivi- sion methods (Shou et al., 2005; Martin et al., 2002) …  相似文献

浙江"特色产业"论     

张德存 《湖州师范学院学报》2002,24(5):60-66

特色经济的核心是特色产业。浙江的特色产业有着独特的发展思路和发展模式；它推动了浙江经济发展、富裕了浙江人民、使浙江快速完成了资本积累；它发挥了浙江优势、调整优化了浙江农村产业、产品结构，以鲜明的特色开辟了浙江独特的市场空间，避免产业趋同和不合理的重复建设；最终形成了与特色产业相配套的龙头企业和专业市场，带动周围地区加工生产进一步发展，提高了浙江农业工业化、集约化程度。这是浙江成为全国经济明星的成本。  相似文献   

The Misspecification of the Covariance Structures in Multilevel Models for Single-Case Data: A Monte Carlo Simulation Study     

Mariola Moeyaert  Maaike Ugille  John M. Ferron  S. Natasha Beretvas  Wim Van den Noortgate 《Journal of Experimental Education》2016,84(3):473-509

The impact of misspecifying covariance matrices at the second and third levels of the three-level model is evaluated. Results indicate that ignoring existing covariance has no effect on the treatment effect estimate. In addition, the between-case variance estimates are unbiased when covariance is either modeled or ignored. If the research interest lies in the between-study variance estimate, including at least 30 studies is warranted. Modeling covariance does not result in less biased between-study variance estimates as the between-study covariance estimate is biased. When the research interest lies in the between-case covariance, the model including covariance results in unbiased between-case variance estimates. The three-level model appears to be less appropriate for estimating between-study variance if fewer than 30 studies are included.  相似文献   

Comparing Student Performance and Growth in 2- and 4-Year Institutions     

Strauss  Linda C.  Volkwein  J. Fredericks 《Research in higher education》2002,43(2):133-161

This study examines the organizational characteristics of 51 higher education institutions in relationship to student performance and growth. The study first finds that organizational measures of mission, size, wealth, complexity, and selectivity are statistically represented by the 2-year versus 4-year college mission. Findings indicate that 2-year and 4-year campuses indeed do exert significantly different influences on undergraduate GPA and self-reported intellectual growth. Next, the study uses both OLS regression and HLM to examine these influences. High school percentile rank and college classroom experiences are better predictors of Cum GPA at 4-year institutions, while student effort is a better predictor of GPA at 2-year institutions. Whereas the most important predictors of Cum GPA include precollege measures such as high school percentile rank and SAT score, the most influential predictors of student intellectual growth are campus experiences including classroom vitality, peer support, student effort, commitment, and involvement. Controlling for all other variables, students at 2-year institutions receive higher grades, and students at 4-year campuses experience more growth.  相似文献
