This study concerns how intra-organizational networks affect the implementation of policies and practices in organizations. In particular, we attend to the role of the informal subgroup or clique in cultivating and distributing locally adapted and integrated knowledge, or know-how. We develop two hypotheses based on the importance of intra-organizational coordination for an organization's capacity for change. The first emphasizes the importance of distributing know-how evenly to potential recipient subgroups. The second emphasizes the importance of restricting know-how to flow from high know-how subgroups. We test our hypotheses with longitudinal network data in 21 schools, finding stronger support for the second hypothesis than the first. Our findings can help managers cultivate know-how flows to contribute to organizational change. The following are appended: (1) Technical Appendix; and (2) Multilevel Estimation of Main Models.

Charter schools have generated support from politicians in both major American political parties, while stimulating intense debate among interest groups. We investigate whether and how public attitudes come to mirror interest group polarization or politician consensus in order to understand what drives public attitudes as policy debates mature and citizens learn information that drives advocates to opposite sides. Using survey experiments, we assess how views change in response to policy cues. Mirroring debates among advocates, we assess whether the role of private companies and non-union teachers polarize opinion. We find that the public responds to cues linked to unions and polarizes based on liberal and conservative ideology as well as attitudes toward unions. This helps to explain how ideological polarization can grow even in the absence of strong partisan sorting among top political leaders. The report includes a bibliography.

Historically, waves of new technologies have brought Americans higher standards of living. Electrical service and hot and cold running water, for example, were once luxuries; now their absence makes a home substandard. Today, technologies for accessing the Internet are diffusing at an even faster rate than those earlier innovations once did, bringing with them commensurate transformations of Americans' way of life. Technologies that increase the speed at which data can be transmitted have had powerful effects. Most importantly, they have transformed the Internet from a tool used by a narrow group of academics and technicians into a means of interaction used by a large majority of Americans. However, Americans have not universally benefitted from better Internet access. Geography, especially the divide between rural and urban America, determines how much some Americans can benefit from the Internet. Networks have not been as extensively developed in rural areas as in urban areas. Some people in rural America still have dial-up as their best available, affordable technology, a technology that offers five percent of the capacity for what the FCC has said is the broadband threshold. Others have service that reaches the broadband level, but still does not offer the "lightning-fast" speeds advertised by Internet service providers in urban areas. Accordingly, the nation faces a "broadband gap," not only with regard to the lack of access in rural areas to service that meets the broadband threshold, but also with regard to the lack of availability of faster service between urban and rural America. This report identifies opportunity costs that arise from this gap. These costs exist today, but the pace at which data transmission capability is growing means that the inequality between the technology being newly deployed and the technology that was deployed a decade or more ago is increasing. Networks that connect research institutions in the United States can move 100,000 times more data per unit of time than the dial-up connections that some Americans still must use. The technology gap is not a fixed deficit that once filled, stays filled. The technology gap will be larger--much larger--in the future, along with the information and technology gap, unless significant action is taken to overcome it.

The rapid proliferation of technology can have profound effects on the evolution of teaching, learning, scholarship, and governance in higher education (Katz, 2008). However, instructors report that simply "keeping up" with new instructional technologies, let alone integrating them productively into one's teaching, can be a significant challenge (Sorcinelli, Austin, Eddy, & Beach, 2006; Zhu, Kaplan, & Dershimer, 2011). This Occasional Paper describes how instructors at the University of Michigan are currently using online collaboration tools (hereafter OCTs) in a variety of disciplines and teaching contexts to enhance student engagement and course management. Based on these cases and faculty interviews, the authors also outline recommendations for implementing OCTs effectively and efficiently in teaching.
