Managed health care deliberations in Oregon point to a "civic bioethics" model to resolve allocation issues through publicly articulated community values and priorities that influence legislative action. Communication practices in the Oregon experiment provide data to develop an evaluative framework to assess public moral deliberation in value-laden contexts such as health care distribution. The Oregon experience also points to dialogical virtues to heighten citizens' ethical sensibilities and political will, discursive tools to inform ethical communication practices in a civic bioethics model.  相似文献

Three students with severe reading disabilities participated in a 3‐year intervention provided by trained tutors from first grade through third grade (175–231 hours). All three students demonstrated very low response to initial levels of intervention and were provided adjusted intensive intervention in an attempt to remedy their low response to instruction. Findings revealed that two of the three students realized limited growth and did not accelerate progress toward reducing the gap between their performance and the expected grade level performance. One student accelerated growth considerably during third grade and made accelerated progress toward grade level expectations. Information on intervention implementation and student progress as well as implications for practice and further research are discussed.  相似文献

In recent years, the landscape for wireless technology has changed substantially, with profound implications for the evolution of last-mile access infrastructure. This paper provides a high-level introduction to emerging trends in wireless technology, with a special focus on how these are impacting municipal broadband deployments. Also discussed are some of the key architectural and design choices for wireless networking systems and their implications for cost and system performance. In addition, examples are provided regarding how the new wireless technologies are being deployed by municipalities in a variety of contexts, with reference to wireless technologies currently available from vendors. The policy implications of these trends are discussed further in a companion paper in this issue.  相似文献

Universal Service: Defining the Policy Goal in the Age of the Internet   总被引:1,自引:0,他引:1  
The current universal service policies for the Internet focus almost entirely on physical connectivity. This emphasis is misplaced because the Internet is an overlay network that rides piggyback on the existing telecommunications infrastructure. The focus instead should be on Internet services and the end-user equipment and training needed to access them.  相似文献

All 12 kindergarten classrooms from a small town/rural Midwestern county were observed for the full session on the first day of school to determine teachers' language and classroom practices. Data collection included completion of a classroom checklist by the investigator and running accounts of classroom events with verbatim notes of teacher language. The findings from this study provide evidence of demands for entering kindergartners to process complex language, organize themselves and their materials, and comply with many new rules and procedures. Based on these data, the author and participating teachers present recommendations for preschool teachers, kindergarten teachers, and researchers. The findings provide convergent validity for previous surveys of teacher expectations for children at kindergarten entry. They can be used by preschool personnel to plan preschool language experiences to assist young children's transition to kindergarten. The method of classroom observation employed here can also help local personnel in varied communities to shape a more seamless system of experiences for the early years.  相似文献

Abstract

We present noncompetitive adsorption as “particles in a box with one sticky wall.” We start with a general model that can be modeled as a simple ordinary differential equation (ODE). To verify the ODE students run a computer simulation. The ODE’s solution imperfectly fits the simulation’s data. This leads to the diffusion partial differential equation. We show how to determine the diffusion constant from theory; how to determine how many terms in the Fourier series solution need to be summed; and the use of nonlinear regression. As a bonus, the physics of the model will lead us to a series representation of π.  相似文献

The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75).  相似文献
