A pillar of the Youngstown community: The Public Library of Youngstown and Mahoning County engages in the Harwood practice

ABSTRACT

The Harwood Institute arrived in Youngstown, Ohio, in 1999; and today, over 18 years later, its teachings have made a profound effect upon the city. The Youngstown Public Library, through the leadership of Carlton Sears and Heidi Daniel, has wholeheartedly embraced the methods and ideology of the Harwood Institute, helping to reinvigorate and power a city working its way back to prosperity.     

The IR Has Two Faces: Positioning Institutional Repositories for Success

This article describes the ongoing efforts at University of Nevada, Las Vegas (UNLV) Libraries to evolve the role of the institutional repository (IR) and to effectively position it within the context of the Libraries’ collections, research support, and scholarly communication services. A major component of this process is re-examining the fundamental aims of the IR and aligning it to the Libraries and the campus strategic goals. The authors situate UNLV Libraries’ experience within the context of the current literature to provide background and reasoning for our decision to pursue two, at times conflicting, aims for the IR: one for scholarly communication and another for research administration.     

Methodological Choices in the Content Analysis of Textbooks for Measuring Alignment With Standards

With the recent adoption of the Common Core standards in many states, there is a need for quality information about textbook alignment to standards. While there are many existing content analysis procedures, these generally have little, if any, validity or reliability evidence. One exception is the Surveys of Enacted Curriculum (SEC), which has been widely used to analyze the alignment among standards, assessments, and teachers’ instruction. However, the SEC can be time‐consuming and expensive when used for this purpose. This study extends the SEC to the analysis of entire mathematics textbooks and investigates whether the results of SEC alignment analyses are affected if the content analysis procedure is simplified. The results indicate that analyzing only every fifth item produces nearly identical alignment results with no effect on the reliability of content analyses.

韩国政府为了实现在21世纪成为“世界超一流国家”的宏伟目标，在对现存教育与人力资源开发体制进行反省的基础上，决定把强化人力资源开发作为国家发展的核心战略。2001年12月制定出台了《人、知识、跨越：国家人力资源开发基本计划》，确立了“提高国民生活质量和国家竞争力”的人力资源开发目标和一系列政策保障措施。     

国外图书馆战略规划调研分析及其启示

[目的/意义]科学化、规范化、定期化的图书馆战略规划对我国图书馆而言仍处于初始发展阶段,调查研究并吸收和借鉴国外图书馆战略规划的相关成果,将加快我国图书馆战略规划的理论与实践发展。[方法/过程]调研国外39份最新图书馆战略规划,以之作为研究样本,分别从战略规划时间长度、战略规划体例、战略规划文本词频等维度进行较为深入的分析与研究。[结果/结论]国外图书馆重视图书馆战略规划工作,重视图书馆战略规划文本的产生与执行,重视战略环境分析以及战略制定过程中各种因素的协调作用,其开展战略规划图书馆之广泛、战略规划时间之连续以及战略规划体例之规范都为我国图书馆战略规划的制定提供了重要启示和宝贵参考。     

黑龙江省冰雪装备制造业创新成长影响要素与战略研究

随着我国成功申办2022年冬奥会,我国将大力发展冰雪运动,并会随之带动旅游、经济和冰雪装备制造业的发展。而冰雪装备制造业的发展直接影响我国冰雪体育事业的开展。采用文献资料、调查、系统分析等研究方法,针对黑龙江省冰雪装备制造业的创新成长问题进行研究,并对黑龙江省的冰雪装备制造业创新成长影响要素以及企业创新成长存在的问题进行分析与总结,认为黑龙江省冰雪装备制造业创新成长的总体状况是良好的,但企业存在资金短缺,经营、管理、技术等方面人才匮乏,企业产品结构单一、产品科技创新意识和能力不强,欠缺可持续发展理念等问题。通过分析影响冰雪装备制造业创新成长的原因,提出引进与自我创新相结合、注重品牌质量、发扬政府主导优势等战略,旨为冰雪装备制造业在黑龙江省的发展提供理论依据。     

创建neighbor-joining进化树的快速算法

为了改善Saitou和Nei提出的neighbor-joining进化树算法(SN)及Studier和Keppler的改进算法(SK),降低计算的时间复杂度,设计了一种快速算法.该算法涉及3种技术第一,引入一个线性数组A[N],用于存储距离矩阵每一行的值,以减少许多重复计算;第二,A[i]的值在算法开始时全部计算,在迭代步中间只进行更新3个变化的值;第三,设计了一个紧凑的公式用于计算OTUs之间的边长,并对该公式进行了证明.实验结果表明随着节点数的增多,该算法比SN算法快几十倍到上百倍,比SK算法快2倍以上;在一台桌面计算机上,该算法能在3min左右创建具有2000个节点的进化树.以空间换时间,减少最内层循环的计算量是设计多重循环算法的基本思路.
