Patterning nanowire and micro-∕nanoparticle array on micropillar-structured surface: Experiment and modeling

DNA molecules in a solution can be immobilized and stretched into a highly ordered array on a solid surface containing micropillars by molecular combing technique. However, the mechanism of this process is not well understood. In this study, we demonstrated the generation of DNA nanostrand array with linear, zigzag, and fork-zigzag patterns and the microfluidic processes are modeled based on a deforming body-fitted grid approach. The simulation results provide insights for explaining the stretching, immobilizing, and patterning of DNA molecules observed in the experiments.     

The diagnostic and prognostic utility of the dual-task tandem gait test for pediatric concussion

Background:The tandem gait test has gained interest recently for assessment of concussion recovery.The purpose of our study was to determine the prognostic and diagnostic use of the single-and dual-task tandem gait test,alongside other clinical measures,within 10 days of pediatric concussion.Methods:We assessed 126 patients post-concussion(6.3§2.3 days post-injury,mean§SD)at a pediatric sports medicine clinic and compared them to 58 healthy controls(age:15.6§1.3 years;43%female).We also compared the 31 patients with concussion who developed persistent post-concussion symptoms(PPCS)(age=14.9§2.0 years;48%female)to the 81 patients with concussion who did not develop PPCS following the initial assessment(age:14.1§3.0 years;41%female).All subjects completed a test battery,and concussion patients were monitored until they experienced concussion-symptom resolution.The test battery included tandem gait(single-task,dual-task(performing tandem gait while concurrently completing a cognitive test)conditions),modified Balance Error Scoring System(mBESS),and concussion symptom assessment(Health and Behavior Inventory).We defined PPCS as symptom resolution time>28 days post-concussion for the concussion group.Measurement outcomes included tandem gait time(single-and dual-task),dual-task cognitive accuracy,mBESS errors(single/double/tandem stances),and symptom severity.Results:The concussion group completed the single-task(mean difference=9.1 s,95%confidential interval(95%CI):6.1-12.1)and dual-task(mean difference=12.7 s,95%CI:8.7
16.8)tandem gait test more slowly than the control group.Compared to those who recovered within 28 days of concussion,the PPCS group had slower dual-task tandem gait test times(mean difference=7.9 s,95%CI:2.0-13.9),made more tandem-stance mBESS errors(mean difference=1.3 errors,95%CI:0.2-2.3),and reported more severe symptoms(mean difference=26.6 Health and Behavior Inventory rating,95%CI:21.1-32.6).Conclusion:Worse dual-task tandem gait test time and mBESS tandem stance performance predicted PPCS in pediatric patients evaluated within 10 days of concussion.Tandem gait assessments may provide valuable information augmenting common clinical practices for concussion management.     

Widening the gap? The challenges for equitable music education in Scotland

Exposure to and potential to engage in music is now very different for children and young people from more middle-class and affluent backgrounds compared to those from working-class or poor households. Middle-class children and young people have access to opportunities to learn an instrument and engage in performance, predominantly for intrinsic reward and on occasion as the basis of a future career. Children and young people from more working class or poor backgrounds are more likely to be excluded from these opportunities and are less likely to take advantage of opportunities within the wider world of music industries. This research draws on in depth case studies of three local authorities in Scotland to reveal the ways in which local provision for music education is largely being reshaped by economic factors and restraints. Drawing on aspects of critical theory it discusses the ways in which economic-based decisions are interacting with the dominant social and cultural values to influence provision. It makes the argument that in an era of austerity the social and cultural values of the middle class are dominant and effectively increasing inequality in access to music. Children and young people from poor or working class households are increasingly excluded from opportunities to engage with formal music provision.

Cultivating the sense of belonging and motivating user participation in virtual communities: A social capital perspective

Virtual communities (VCs) are attracting more attention as they provide a platform for people to share experiences and knowledge, which may further impact their purchase decisions. From a social capital perspective, this study investigated factors that cultivate a VC member's sense of belonging and their effects on facilitating his participation in the VC in terms of the intentions to get and share experiences and knowledge. The results indicated that three factors that relate to three dimensions of social capital in the VC – familiarity with members in the VC from the structural dimension, perceived similarity with other members from the cognitive dimension, and trust in other members from the relational dimension – are all positively related to the sense of belonging, which affects intentions to get and share knowledge and mediates the relationships between social capital factors and a VC member's intentions to participate.     

An intervention for relational and physical aggression in early childhood: A preliminary study

A preventive intervention for reducing physical and relational aggression, peer victimization, and increasing prosocial behavior was developed for use in early childhood classrooms. Nine classrooms were randomly assigned to be intervention rooms (N = 202 children) and nine classrooms were control rooms (N = 201 children). Classroom was the unit of analysis and both observations and teacher-reports were obtained at pre and post-test. Focus groups were used to develop the initial program. The 6-week program consisted of developmentally appropriate puppet shows, active participatory sessions, passive concept activities and in vivo reinforcement periods. Preliminary findings suggest that the “Early Childhood Friendship Project” tended to reduce physical and relational aggression, as well as physical and relational victimization and tended to increase prosocial behavior more for intervention than control classrooms. Teachers and interventionists provided positive evaluations of the program and there is evidence for appropriate program implementation.     

Performance,Perseverance, and the Full Picture of College Readiness

Although college readiness is a centerpiece of major educational initiatives such as the Common Core State Standards, few systems have been implemented to track children's progress toward this goal. Instead, college‐readiness information is typically conveyed late in a student's high‐school career, and tends to focus solely on academic accomplishments—grades and admissions test scores. Late‐stage feedback can be problematic for students who need to correct course, so the purpose of this research is to develop a system for communicating more comprehensive college‐readiness diagnoses earlier in a child's K‐12 career. This article introduces college‐readiness indicators for middle‐school students, drawing on the National Education Longitudinal Study of 1988 (NELS), a nationally representative longitudinal survey of educational inputs, contexts, and outcomes. A diversity of middle‐school variables was synthesized into six factors: achievement, behavior, motivation, social engagement, family circumstances, and school characteristics. Middle‐school factors explain 69% of the variance in college readiness, and results suggest a variety of factors beyond academic achievement—most notably motivation and behavior—contribute substantially to preparedness for postsecondary study. The article concludes with limitations and future directions, including the development of college‐readiness categories to support straightforward communication of middle‐school indicators to parents, teachers, and students.     

Strategic Engagement: New Models of Relationship Management for Academic Librarians

ABSTRACT

How do we best bridge the gap between the Library and the diverse academic communities it serves? Librarians need new strategies for engagement. Traditional models of liaison, aligning solutions to disciplines, are yielding to functional specialisms, including a focus on building partnerships. This paper offers a snapshot of realignment across the Russell Group from subject support to relationship management. It then follows the journey of a newly-formed Faculty and School Engagement Team. Techniques are explored for building relationship capital, anchored to a model Strategic Engagement Cycle. Theory is contrasted with the challenges of securing real buy-in to new ways of working amid diverging agendas and assumptions, notably within the Library itself. Consideration is given to the retention of aspects of subject librarian roles. Investment in a relationship management function demands staunch and ongoing commitment to fulfil its promise, not only from its performers but from across the library community.     

‘Let's Talk Autism' –a school‐based project for students to explore and share their experiences of being autistic

Understanding what autism means on a personal level can be an important process for young people on the autistic spectrum, and being able to reflect on this and discuss with autistic peers can be particularly helpful. However, opportunities may be restricted by reluctance to talk about diagnosis and because of difficulties in communication inherent in autism. This article describes a therapeutic media project within an ASD school that attempted to support young people to reflect together about what autism meant for them and create resources to share with others. The process is described and main themes of discussions analysed using thematic analysis. Main themes emerged of making sense of diagnosis, experiences of difference and transition to adulthood. Various strategies to manage diagnosis and negotiate identity also emerged. Issues around informed consent and confidentiality and the therapeutic value of such groups are discussed.
