  • Hello, I’m Kelsi Dayle Anderson and I’m a Master’s candidate at the Humphrey School of Public Affairs in Science, Technology, and Environmental policy. My interest lies in promoting public engagement, specifically towards environmental policy, through science communication and education. At the Institute on the Environment’s Dialogue Earth program, I am developing a methodology to identify the characteristics of *this* subset of news stories with the goal of then using those findings to guide scientists’ engagement with the public. “This* subset of news stories is particularly interesting because they “make it” in both the traditional and emerging media, thereby reaching the largest audience. This research will form the basis of my thesis, which I’m beginning this semester and plan to defend in next December.
  • I want to let you know that the majority of the research that I’m going to be citing is not my own . I’m sharing the work of others who have been studying technology use, learning and social media – and it’s a huge field – and some who have looked at parents. In my own lab we have ongoing research and planned research on 1) how and which parents use which technology for parenting, a baseline survey , 2) we’re evaluating existing online sites for parents – MN Parents Know, JITP, 3) we’re going to be creating social networking, geomapping technology for parents related to locating and sharing information about activities for young children, and 4) we’re looking at professional parents educators’ integration of technology . From use to product to evaluation to integration in practice. Perhaps if I run into you in a year I’ll have some of our results to share. You may have noticed the survey on your table . This is part of a study – looking at community-based educators’ attitudes about technology If you would fill it out during the talk, I’d appreciate it. There’s an information sheet on the table that tells more about the study. It’s optional of course, but I’d love your voice and experience to be considered in the research. Thanks very much.

Currently, more than 530 providers (chiefs of cardiology, chiefs of medicine, chiefs of staff, clinicians, researchers, nurse practitioners, physician assistants, pharmacists, facility and VISN leadership, and others) from 150 facilities participate in this network. Questions: How is the HF network organized? What is the impact of the HF networks activities on patient care? Does this impact vary by activity, degree of participation and location in the network? <ul><li>Activities </li></ul><ul><li>Share experiences with HF care programs </li></ul><ul><li>Exchange HF tools </li></ul><ul><li>Collaborate on registries and improvement </li></ul><ul><li>Support collaborative research on HF care </li></ul>
