浓墨重彩述时代殚心竭力写春秋--兼谈《秦安县志》的编修

编写地方志是中华民族的优良传统.20世纪80年代,甘肃省在全省范围内开展了第一届新编地方志工作,至2000年,全省修志任务基本完成.《秦安县志》就是本届修志的优秀成果之一.总结《秦安县志》编修的过程与体会,在一定程度上就是在总结本届修志经验和教训.编修方志必须严把篇目关、资料关、编写关和审稿关,注意地方特色的体现,这样才能编修出胜人一筹的地方志来.

PowerUp!: A Tool for Calculating Minimum Detectable Effect Sizes and Minimum Required Sample Sizes for Experimental and Quasi-Experimental Design Studies

Abstract

This paper and the accompanying tool are intended to complement existing supports for conducting power analysis tools by offering a tool based on the framework of Minimum Detectable Effect Sizes (MDES) formulae that can be used in determining sample size requirements and in estimating minimum detectable effect sizes for a range of individual- and group-random assignment design studies and for common quasi-experimental design studies. The paper and accompanying tool cover computation of minimum detectable effect sizes under the following study designs: individual random assignment designs, hierarchical random assignment designs (2-4 levels), block random assignment designs (2-4 levels), regression discontinuity designs (6 types), and short interrupted time-series designs. In each case, the discussion and accompanying tool consider the key factors associated with statistical power and minimum detectable effect sizes, including the level at which treatment occurs and the statistical models (e.g., fixed effect and random effect) used in the analysis. The tool also includes a module that estimates for one and two level random assignment design studies the minimum sample sizes required in order for studies to attain user-defined minimum detectable effect sizes.     

An algorithmic approach for system decomposition and balanced realized model reduction

This paper deals with the development of an algorithm for unstable continuous/discrete-time system decomposition into completely stable and completely unstable subsystems using real Schur transformation technique. The application of the proposed algorithm is investigated for unstable LTI plant or controller reduction and the available balanced realized model reduction theories applicable for stable systems are extended for unstable, continuous/discrete-time systems. The algorithm and its applications are illustrated with MATLAB-based computer-simulated results for continuous and discrete-time systems.     

高职教育园区管理协同效应及其实现途径

随着高职教育园区的迅速发展以及对高职园区办学效益的日益重视,高职教育园区自身管理能力及资源共享、能力互补和产学研一体化方面产生的协同效应得到普遍关注。推进高职园区加快集约化发展,快速形成协同效应,关键在于充分发挥政府主导和财政导向作用,明确各利益方的责、权、利,促进和吸引园区各办学主体加快开放共享资源,实现优势互补。同时,各校也要注重特色建设,避免协同发展的负效应。
