Early Adverse Experiences and Repeated Wheezing From 6 to 30 Months of Age: Investigating the Roles of Hypothalamic–Pituitary–Adrenal Axis Functioning,Child Sex,and Caregiving Sensitivity

This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing.     

Many Voices: Building a Biblioblogosphere in Ireland

ABSTRACT

Blogging has been associated with the Library and Information Science (LIS) community for some time now. Libfocus.com is an online blog that was founded in 2011. Its goal was to create a communal communication space for LIS professionals in Ireland and beyond, to share and discuss issues and ideas. The content of the blog is curated by an editorial team and features guest bloggers from across all sectors and experience levels. Using a qualitative methodological approach, open-ended surveys were conducted with twelve previous guest bloggers, in order to explore how and why Irish-based LIS professionals choose to communicate through blogging. It is hoped that this evidence will provide a greater understanding of both the value and effectiveness of blogging as an outreach and communication tool within the profession, helping both libraries and librarians to be more strategic in their use of it as a medium.     

Storying Joanne, 1 an undergraduate mathematician

In this article two different accounts are juxtaposed. In one, we use a variety of texts to narrate the story of Joanne, a woman undergraduate student of mathematics. Like many of our mature students Joanne came to the university with a ‘non‐traditional’ academic background. We describe how Joanne developed as a learner of mathematics and connect this to our ways of working in the undergraduate mathematics classroom. We believe that our pedagogy is unusual outside (some) school classrooms and suggest it allows our students to develop positive ‘disciplinary relationships’. In the other, we grapple with the issues raised by telling other people’s stories especially when we are also characters within it. Our intention has been that, in interweaving these two threads, each helps us understand more about the other.     

What are Middle School Students Talking About During Clicker Questions? Characterizing Small-Group Conversations Mediated by Classroom Response Systems

There is a growing interest in using classroom response systems or clickers in science classrooms at both the university and K-12 levels. Typically, when instructors use this technology, students are asked to answer and discuss clicker questions with their peers. The existing literature on using clickers at the K-12 level has largely focused on the efficacy of clicker implementation, with few studies investigating collaboration and discourse among students. To expand on this work, we investigated the question: Does clicker use promote productive peer discussion among middle school science students? Specifically, we collected data from middle school students in a physical science course. Students were asked to answer a clicker question individually, discuss the question with their peers, answer the same question again, and then subsequently answer a new matched-pair question individually. We audio recorded the peer conversations to characterize the nature of the student discourse. To analyze these conversations, we used a grounded analysis approach and drew on literature about collaborative knowledge co-construction. The analysis of the conversations revealed that middle school students talked about science content and collaboratively discussed ideas. Furthermore, the majority of conversations, both ones that positively and negatively impacted student performance, contained evidence of collaborative knowledge co-construction.     

Negotiating status hierarchies in middle school inquiry science: implications for marginal non-participation

Measuring perceived social support: Development of the child and adolescent social support scale (CASSS)

The measurement of students' social support has become a popular topic in education and psychology, yet measurement tools in this area are limited. In this study, we use a large, representative sample to conduct confirmatory factor, reliability, and correlational analyses of scores on the Child and Adolescent Social Support Scale (CASSS; Malecki, Demaray, Elliott, & Nolten, 1999). These analyses revealed evidence of reliability, a four‐factor structure (Parent, Teacher, Classmate, and Close Friend subscales), and construct validity. The results of this study indicate that the CASSS covaries as predicted with the clinically important constructs of self‐concept, social skills, and behavioral indicators. There is evidence that the CASSS can be used to understand children and adolescents' perceived social support. © 2002 John Wiley & Sons, Inc.
