This article examines an informal online community dedicated to The Tudors, a historical television show, and the ways in which its members engaged with a variety of sources in their discussions of the drama’s real-life past. Data were collected over a 5-month period. The analysis included the types of sources used in conversation; members’ purpose for invoking and reaction to sources; as well as topic, participation, and response patterns in the discussion forum. The community is a space in which popular culture and the discipline of history meet. Members come together because of a fictional depiction of the past, yet a desire to corroborate, clarify, contextualize, or uncover what really happened leads users to participate in detective-like inquiry work and the learning of new topics they had not previously considered. Members also challenge and critique one another’s positions and the sources other members invoke in multiple ways, including by using more formal disciplinary heuristics in this informal setting. Key differences emerge in members’ purpose for invoking sources, with popular media used more frequently for illustrating a point or asking a question and nonfiction works most invoked to support and argue historical claims.  相似文献

It is increasingly important for government agencies to collaborate across jurisdictional and functional boundaries. Interorganizational systems supporting interagency collaboration must accommodate a wide range of factors from the external environment and participating organizations as part of their design and operation. This paper presents the findings from a case study of CapWIN, a collaborative network created to enable first responders to share information across jurisdictional and functional boundaries as they work together during emergencies and other critical events. The study examines how aspects of the external environment and the agency context impeded or facilitated the CapWIN collaborative network and the interorganizational system (IOS) that supports it. We identify factors affecting information sharing and collaborative processes, and describe how these factors interact to enable and constrain an IOS. The paper concludes with suggestions for further research on the interplay of environmental, organizational, and technical aspects of interagency collaboration networks as they evolve over time.  相似文献

This paper examines how teachers responded when some organizational constraints on their work were loosened and why they responded as they did. It first reviews the sociological literature on teacher work to identify the main determinants studied. It then presents results of an ethnographic study of teachers in an urban school. The literature tends to portray teacher work as overly determined and may remove more responsibility from teachers for determining their own work than is warranted.  相似文献

A study is made of the orthogonal polynomials on certain curves in the complex plane. Necessary and sufficient conditions for a set of polynomials to be orthogonal on the curves are obtained in terms of symmetric matrices. The relations of the symmetric matrices to Toeplitz matrices and innerwise matrices are shown.  相似文献

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children's self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children's preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children's self-regulation as a hypothesized mediator for children's gains in academic readiness. Implications for programs and policies that support young children's behavioral health and academic success are discussed.  相似文献
