Working alongside people who use and manage a local charity and professional quilters, we sewed a quilted blanket which we augmented with capacitive touch sensors to turn the craft Piece into an interactive archiver. In this way, the quilt tells the story of the women who were involved in making it not only through the seams, but also with our embedded voices. We describe the process of quilting a digitally augmented social fabric and the ways in which the sewing allowed us to learn through the seams, we present a project that brings together aspects of human connection, crafted learning, and living archival practice.  相似文献

Government agencies often face trade-offs in developing initiatives that address a public good given competing concerns of various constituent groups. Efforts to construct data warehouses that enable data mining of citizens’ personal information obtained from other organizations (including sister agencies) create a complex challenge, since privacy concerns may vary across constituent groups whose priorities diverge from agencies’ e-government goals. In addition to privacy concerns, participating government agencies’ priorities related to the use of the information may also be in conflict. This article reports on a case study of the Integrated Non-Filer Compliance System used by the California Franchise Tax Board for which data are collected from federal, state, and municipal agencies and other organizations in a data mining application that aims to identify residents who under-report income or fail to file tax returns. This system pitted the public good (ensuring owed taxes are paid) against citizen concerns about privacy. Drawing on stakeholder theory, the authors propose a typology of four stakeholder groups (data controllers, data subjects, data providers, and secondary stakeholders) to address privacy concerns and argue that by ensuring procedural fairness for the data subjects, agencies can reduce some barriers that impede the successful adoption of e-government applications and policies. The article concludes that data controllers can reduce adoption and implementation barriers when e-government data mining applications rely on data shared across organizational boundaries: identify legitimate stakeholders and their concerns prior to implementation; enact procedures to ensure procedural fairness when data are captured, shared, and used; explain to each constituency how the data mining application helps to ensure distributive fairness; and continue to gauge stakeholders’ responses and ongoing concerns as long as the application is in use.  相似文献

Children seem to be natural problem solvers and delight in the challenges that are provided for them. Teachers who are careful observers of what children do can begin to provide many opportunities for helping them build their skills in problem solving. At the same time, it is important to let children create and solve some of their own newly discovered problems. A balance of both seems to be important to solving problems.Janis Bullock is Instructor of Early Childhood Education at Montana State University in Bozeman.  相似文献

OBJECTIVE: This paper explores the characteristics associated with decisions to adopt or discontinue the use of filtering software, including a critical analysis of some explanations about why it is used or not used in households with children and adolescents. METHOD: This study consisted of a national telephone survey of households in the United States with youth (10 and 17 years) who use the Internet regularly. Interviews were completed with one youth in the appropriate age group and a parent or caretaker. RESULTS: Thirty-three percent of parents reported using filtering or blocking software, with an additional 5% having discontinued its use within the past year. Parents were more likely to adopt filtering software if they had younger children (10--15 years), a high level of concern about exposure to sexual material on the Internet, more extensive knowledge of what their child did online, low trust in the child's ability to use the Internet responsibly, and if the child used America Online (AOL). Using the Internet for school assignments was associated with not having filtering software. CONCLUSION: Findings suggest the need for (1) evaluation research of filter programs used in a real family context and (2) the development of a variety of strategies to prevent exposure to inappropriate material for youth of different ages.  相似文献
