Family disruption and academic functioning in urban,black youth

The purpose of this study was to examine from an ecological perspective the relationships between multiple levels of family disruption and children's academic functioning in a sample of 390 urban, Black adolescents at age 14. Subjects in this cohort have been followed longitudinally since before their birth. Data from previous assessments at birth and age 7 years allowed for control of important correlates in this analyses. Examination of this unique sample, using multisource data collection procedures, provides important information about the many family disruptions among urban, low‐income families and the effects of these disruptions on academic outcomes. Results revealed several consistent findings, the most notable of which is that, when parents were married, adolescents demonstrated significantly higher grades, mediated through paternal involvement. Of all variables studied, the role of fathers in the lives of these adolescents was the most influential on academic outcomes. In this unique sample, even variables such as involvement with child protective services were not significantly related to outcomes after important control variables were factored into analyses. Results of this study have important implications for future research and for prevention and intervention efforts in urban, at‐risk samples. Emphasis is made for work in the school context, particularly for school psychologists. © 2011 Wiley Periodicals, Inc.     

Researching Telemedicine: Capturing Complex Clinical Interactions with a Simple Interface Design

Telemedicine has been shown to be an effective means of managing follow-up care in chronic diseases such as depression. Exactly why telemedicine calls work, however, remains largely unknown because there are no adequate research tools to describe the complex communicative interactions in these encounters. We report here an ongoing project to investigate the efficacy of telemedicine in depression care, arguing that technical communication specialists have unique contributions to make to this kind of research.     

Assessing Students With Disabilities: Issues and Evidence

Historically, many students with disabilities were excluded from large-scale assessments. Recent federal and state policy initiatives, including the most recent reauthorization of the Individuals With Disabilities Education Act, require that the large majority of students with disabilities be included in the statewide assessments used in accountability systems. Although most observers agree that educational outcomes for students with disabilities were inadequate before the new policies were implemented, the research undergirding the new policies is limited. The reforms have spurred a rapid increase in relevant research, but more and improved research is needed. This article reviews the status of research on issues that are central to the new reforms and recommends directions for future research.     

One Hundred Strong: A Colloquium on Transforming Natural History Museums in the Twenty‐first Century

In February 2012, the Smithsonian's National Museum of Natural History (NMNH) convened 100 colleagues from 43 organizations to initiate a collaborative learning research agenda focused on examining important areas for innovation to better serve twenty‐first‐century audiences. The conference organizers anticipated that scientists, educators, exhibit professionals, and other members of the natural history community would identify and prioritize research questions about what, how, why, when, and where people learn about natural history. We prepared to engage in a conversation about how natural history museums could change what they do. The participants' overwhelming passion for their work, and for natural history museums and their transformative potential for society, quickly turned the conversation toward how natural history museums should change what they are. The result was an emergent learning research agenda situated within a broader vision for natural history museums.     

Value Chain Adjustments in Educational Publishing

This paper looks at at the impacts and implications of new technology for educational publishing in the context of major growth in e-Learning. Although it acknowledges the continuing influence of textbooks both on how emerging technologies will drive changes to courses and the pace at which courses evolve, the major focus is upon the impact of technological and organisational change upon the value chains for e-Learning and educational publishing. It reviews relevant developments in technology, e-Learning and educational publishing and the connections between them, using recent examples. Fundamental to the nexus between technology, e-Learning and publishing is the search for value and for new means of creating and leveraging value in a turbulent higher education marketplace. The subjective nature of value is recognised in the context of different stakeholders. The paper then links changing perceptions of value to a perceived shift within educational publishing, which entails moving from the more or less homogeneous delivery of packaged content towards the provision of truly customised learning services combining use of the latest technologies with access to high quality content. The kinds of value, old and new, provided by educational publishers are compared in a table. This shift in value is then explained in the context of value chains for e-Learning and for educational publishing. So far as educational publishing is concern there are signs of both disintermediation and reintermediation in the value chain. Amidst these changes, the position of educational publishing appears set to improve through its potential to provide a new range of integrated technology and content services.     

Should great lakes city build a new power plant? How youth navigate socioscientific issues

There is a growing consensus that simply learning enough science to decipher public debates on socioscientific issues will not make citizens better equipped to handle the complex and ill‐structured problems these controversial issues present. This study highlights the interaction and complex interplay between youth authored and appropriated frames for making sense of socioscientific issues. To do so, we analyze how two middle‐school aged youth, in an after‐school program focused on green energy technologies, made sense of and took a stance on whether their city should build a new hybrid power plant over the course of a 13‐week unit. Using critical sociocultural perspectives on learning and qualitative case study, we examined how the two youth navigated the issue and the resources, scientific and otherwise, they leveraged in defining the problem spaces involved in whether their city should build a new power plant. Our findings indicate that the scientific knowledge youth brought with them and acquired over the course of the investigation influenced how they made sense of the issue, but their knowledge was deeply connected to a range of personal and public discourses that influenced how they defined the issue and why it mattered to them. In particular, it was through how they framed their range of knowledge and experiences that they were able to recognize the multi‐dimensional nature of the problem and propose complex solutions resonant with the science they understood. Our study offers conceptual tools for teaching and learning socioscientific issues. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 541–567, 2012     

Characterizing disability in Head Start programs: Not so clearcut

Head Start programs are required to set aside at least 10% of program slots for children with disabilities, but the percentage of children with disabilities served varies depending on the criteria used and source of the information. This study used the Head Start Family and Child Experiences Survey (FACES) 2000 data for a nationally representative sample to identify subgroups of children meeting three different criteria for having a disability or developmental delay. Results indicated that about one-third of children in Head Start (33%) met one or more of the criteria for a disability or delay, about one-third of those children (33%) met criteria for two or for all three of the subgroups. However, only 8% of children in Head Start had an Individualized Education Program (IEP). Children with disabilities or delays, regardless of the subgroup criteria used, had higher levels of many other risk factors associated with poor developmental and school readiness outcomes. They also exhibited poorer performance on early literacy, social, and behavioral measures both at entry into Head Start and at the end of kindergarten compared with children not in each of those subgroups. Implications of the findings for screening and assessment, serving children in Head Start programs, and the need for linkages between Head Start programs and the preschool special education system are discussed.     

Multiphysics extension to physically based analyses of pipes with emphasis on frost actions

Pipes, especially buried pipes, in cold regions generally experience a rash of failures during cold weather snaps. However, the existing heuristic models are unable to explain the basic processes involving frost actions. This is because the frost action is not a direct load but one that causes variations in pipe-soil interactions resulting from the coupled thermohydro-mechanical process in soils. This paper developed and implemented a holistic multiphysics simulation model for freezing soils and extended it to the analysis of pipe-soil systems. The theoretical framework was implemented to analyze both static and dynamic responses of buried pipes subjected to frost actions. The multiphysics simulations reproduced phenomena commonly observed during frost actions, e.g., ice fringe advancement and an increase in the internal stress of pipes. The influences of important design factors, i.e., buried depth and overburden pressure, on pipe responses were simulated. A fatigue cracking criterion was utilized to predict the crack initialization under the joint effects of frost and dynamic traffic loads. The frost effects were found to have detrimental effects for accelerating fatigue crack initialization in pipes.
