In 1884, a street corner harangue by the local precinct captain precipitated a torch light parade; the coming of a presidential aspirant caused the whole countryside to erupt. This article presents some of the color, bustle, hysteria, and rhetoric which accompanied James G. Blaine's week‐long but fruitless effort to capture the electoral votes of a crucial state.  相似文献

In recent years, many U.S. states have introduced growth models as part of their educational accountability systems. Although the validity of growth‐based accountability models has been evaluated for the general population, the impact of those models for English language learner (ELL) students, a growing segment of the student population, has not received sufficient attention. We evaluated three commonly used growth models: value tables or transition matrices, projection models, and student growth percentiles (SGP). The value table model identified more ELL students as on track to proficiency, but with lower accuracy for ELL students. The projection and SGP models were more accurate overall, but classified the fewest ELL students as on track and were less likely to identify ELL students who would later be proficient. We found that each model had significant trade‐offs in terms of the decisions made for ELL students. These findings should be replicated in additional state contexts and considered in the development of future growth‐based accountability policies.  相似文献

The majority of today's scholarly papers are authored in Microsoft Word. Some of those papers include simple and/or complex math. Authors have at their disposal multiple means to insert equations in Word documents, including several of Word's native equation editors and third‐party applications, such as Design Science's MathType. Building workflows that smoothly and accurately transform all of these formats into the appropriate XML markup for use in multiple rendering environments has many challenges. This paper clarifies the different forms of equations that can be encountered in Word documents and discusses the issues and idiosyncrasies of converting these various forms to MathML, LaTeX, and/or images in the JATS XML model. It also touches on workflow alternatives for handling equations in various rendering environments and how those downstream requirements may affect the means of equation extraction from Word documents.  相似文献

Attitudes and approaches toward the collection, use, and care of color photographs have evolved enormously since the official arrival of commercially viable color photographic processes in the early twentieth century. This article traces the evolution of collection, exhibition, and preservation practices for works of art in color photography over the last few decades, as represented by one institution, The Metropolitan Museum of Art.  相似文献

ABSTRACT

This essay examines the cross-cultural communication strategies deployed by a coalition of indigenous tribes in Virginia to leverage the Quadricentennial commemoration of the founding at Jamestown in support of their sovereignty campaign. The tensions between Jamestown’s mythos as the “birthplace of democracy” and the natives’ historical and contemporary lived experiences, combined with the national and international attention focused on the events, constructed the 400th anniversary “celebrations” as a compelling location for social action. The coalition employed intercultural communicative practices—particularly cross-cultural dialogue and negotiation—as means of mobilizing these tensions to renegotiate their relationship with the federal government, illustrating the intersection of intercultural communication, memory, and identity.  相似文献
