Rummaging through dustbooks: An analysis of independent small presses

Conclusion Small presses are a colorful and wildly variegated lot. They offer materials on every imaginable topic to suit almost any taste and are springing up in towns and hamlets all over the country. New presses are being founded at a furious rate, though their ability to survive is as yet unknown. Clearly, many presses exist for other than purely commercial reasons. Our analysis suggests that only about a sixth of the 1700-odd publishers for which we have data are serious commercial enterprises; well over half, perhaps as many as two-thirds of them, exist for other reasons—personal interests, hobbies, or special causes.     

Bridging the Partisan Divide? Exploring Ambivalence and Information Seeking Over Time in the 2012 U.S. Presidential Election

Research has shown that holding conflicted attitudes (ambivalence) about political decisions may lead people to act as ideal citizens. One example of this normatively ideal behavior is seen in research linking ambivalence to information seeking. To expand on this line of inquiry, this study examines the over-time relationship between ambivalence and information seeking. We use three-wave panel data collected during the 2012 election to determine whether over-time relationships exist between these variables and test the causal direction of these relationships. We find that use of counterattitudinal information increases ambivalence, which leads people to seek out more counterattitudinal information. We also find that use of pro-attitudinal media decreases levels of ambivalence.     

Reading and the Neurocognitive Bases of Statistical Learning

ABSTRACT

The processes underlying word reading are shaped by statistical properties of the writing system. According to some theoretical perspectives, reading acquisition should be understood as an exercise in statistical learning (SL). SL involves the extraction of organizing principles from a set of inputs. Several lines of research provide convergent evidence supporting the connection between SL and reading acquisition. An obstacle to fully appreciating the theoretical and educational implications of these findings is that SL is itself not well understood. In this article, we review the current literature on SL with a particular focus on organizing this literature by grounding it in theories of learning and memory more generally. This approach can clarify the nature of SL and provide a framework for understanding its role in reading, reading acquisition, and reading disorders.     

基于PCA-CMAC的设备性能退化评估

提出了一种用于设备性能退化评估的PCA-CMAC(主成分分析-小脑模型节点控制器)模型.该模型利用PCA进行特征提取,去除多个传感器信号特征的冗余信息,并且减少CMAC的输入维数;利用CMAC的局部泛化能力定量地评估设备的性能退化.给出了模型的实现过程,并将模型应用于钻削过程刀具状态的评估,试验结果证明该模型能基于刀具的正常状态,对刀具的磨损状态进行定量的评估.分析了CMAC中泛化参数g和量化参数r对评估结果的影响,g越大,CMAC的泛化能力越好,但各退化状态之间的区别越不明显;r越小,各退化状态之间越容易区分,但所需的权存储空间越大.2个参数的基本选择原则是CMAC的权存储空间应尽量小,与此同时,各退化状态之间应容易区分.     

CoRE: A conceptual model for incorporating conflict resolution into teacher education

Abstract

School districts throughout the United States have responded in different ways to recent acts of violence. Responses vary from external security measures, which include metal detectors, see‐through backpacks, and fences, to programs that train teachers and students to recognize potentially dangerous threats and behavior. Literature indicates that teacher education programs have generally failed to address this issue in preservice teacher education. The purpose of this article is to present a conceptual model for incorporating conflict resolution in preservice teacher education. The CoRE model offers teachers conflict resolution/ peer mediation skills in a four‐level approach: Foundational Knowledge, Integration, Contextual, and Implementation.
