Explicit Self-Regulated Strategy Development Versus Reciprocal Questioning: Effects on Expository Reading Comprehension Among Struggling Readers.

The effects of 2 rigorous strategic approaches to reading comprehension for 32 5th-grade students who struggle with reading were investigated. The first approach, TWA (Think before reading, think While reading, think After reading), was taught following explicit self-regulated strategy development instructional procedures (K. R. Harris & S. Graham. 1999). The second approach, reciprocal questioning (RQ), was taught following Cooperative ReQuest procedures developed by A. V. Manzo. U. C. Manzo, and T. H. Estes (2001). Compared with RQ students, TWA students improved significantly (with medium to large effect sizes) on 5 oral reading comprehension measures. There were no significant differences, however, between groups on 3 written comprehension measures, self-efficacy, or motivation. Students were positive about each intervention.

树立职业价值观 做好读者服务工作

明确图书馆读者服务工作的内涵以及图书馆读者服务工作存在的问题,了解正确职业价值观对图书馆工作的重要作用,探讨如何以正确的职业价值观来更好地为读者服务,这对图书馆馆员提高自身的读者服务工作水平具有重要的现实意义。     

谈我院数字资源的使用与服务

影响数字化资源利用率的因素除了读者本身的原因外,还包括数据库使用的便捷程度与图书馆对读者的服务方式。通过对图书馆现有服务方式及其效果的评价,提出要提高数字化资源利用率就必须了解读者的需求、加大对数字化资源的宣传、有计划地实施读者培训与辅导答疑等。

浅论高校图书馆对大学生读者的心理优化功能

高校图书馆对大学生读者具有心理优化功能，在心理素质教育方面具有稳定和谐的感化作用。其心理优化功能表现在丰富学生情感、培养学生意志和自我意识，以及塑造学生健全性格等方面。     

论林白小说的叙述选择

真实与虚构并行、杂糅共存于文本中，采用这种叙述技巧使林白的小说充满了象征意义和语言美感。与此同时，这一技巧的运用对林白小说的意义远不止技巧层面本身。它分别作用于文本、作者、读者并使其间达到了沟通。对于文本：真实与想象杂糅赋予作品以张力，文本中的事件通过换装取消了传统意义上的本质与真实使文本呈现出象征和寓言的氛围。对于作者：林白借真实与虚构的杂糅处理和重建了与常规相对的女性的历史，她跳出了个人主义视角，将自我这一概念扩展到女性这一群体层面。对于读者：林白以一种不彻底的坦诚和不彻底的遮蔽的姿态引导读者去猜测事件的真相，这其中除了对真实本身的好奇心，更有对变幻的文本背后的象征指向的探索欲。真实与虚构的换装不应仅仅被视作炫技，而是到达象征中心的必由之路。

图书信息检索中读者兴趣偏好挖掘模型的建立仿真

针对传统挖掘模型对图书信息检索中读者兴趣偏好数据进行挖掘时,存在的挖掘效率低、耗时长等问题,提出基于聚类分析的读者兴趣偏好挖掘模型.采用分类索引分布树法对图书相似度与读者兴趣距离进行计算,通过兴趣因子对兴趣偏好度进行度量,并以此为基础,采用相关反馈模型Rocchio算法对读者兴趣图书检索进行扩展,引入聚类分析法建立图书信息检索中读者兴趣偏好挖掘模型.实验仿真结果表明,采用改进模型时,其挖掘效率、时间及误差均优于传统模型.     

Identification and Structure–Activity Relationship Studies of Small‐Molecule Inhibitors of the Methyllysine Reader Protein Spindlin1

The methyllysine reader protein Spindlin1 has been implicated in the tumorigenesis of several types of cancer and may be an attractive novel therapeutic target. Small‐molecule inhibitors of Spindlin1 should be valuable as chemical probes as well as potential new therapeutics. We applied an iterative virtual screening campaign, encompassing structure‐ and ligand‐based approaches, to identify potential Spindlin1 inhibitors from databases of commercially available compounds. Our in silico studies coupled with in vitro testing were successful in identifying novel Spindlin1 inhibitors. Several 4‐aminoquinazoline and quinazolinethione derivatives were among the active hit compounds, which indicated that these scaffolds represent promising lead structures for the development of Spindlin1 inhibitors. Subsequent lead optimization studies were hence carried out, and numerous derivatives of both lead scaffolds were synthesized. This resulted in the discovery of novel inhibitors of Spindlin1 and helped explore the structure–activity relationships of these inhibitor series.     

一种用于900MHz射频识别(RFID)读写器芯片的1.8VCMOS直接变频接收机

设计了针对解决900MHz RFID读写器收发机芯片中本地载波干扰问题而优化的直接变频接收机,并在0.18μm 1P6M混合信号CMOS工艺上实现验证.设计中使用了一种串联反馈结构的基带放大器以达到同时实现无源混频器输出缓冲,直流消除以及信号放大的功能.实际测量显示,该接收机的输入1dB压缩点为-4dBm,当中频信号解调信噪比要求为10dB时,可达到的灵敏度为-70dBm.该接收机与整个收发机集成在同一块芯片中,使用1.8V电源电压,工作时静态电流为90mA.
