Breast motion asymmetry during running

Breast asymmetry is common in females, despite a similar driving force; dynamic activity may result in asymmetrical breast motion. This preliminary study investigated how breast categorisation (left/right or dominant/non-dominant) may affect breast support recommendations and its relationship with breast pain. Ten females ran on a treadmill at 10 kph in three breast supports (no bra, everyday bra, sports bra). Five reflective markers on the thorax and nipples were tracked using infrared cameras (200 Hz) during five running gait cycles in each breast support. Multiplanar displacements of both breasts were calculated relative to the thorax. Although the maximum individual participant difference was 2.4 cm (mediolaterally) between the left and right breast, no left/right differences were found in any direction or support condition. Notably, correlations between breast pain and anterioposterior breast displacement were stronger with the left breast (r = 0.614) and moderate with the right breast (r = 0.456). Following participant categorisation according to the greatest magnitude of superioinferior breast displacement (dominant breast), results showed significant differences in displacement for all directions across different breast supports. When using breast kinematic data to examine relationships with breast pain or to recommend breast support requirements, data on both breasts should be collected.     

Instructing First-Grade Children on Patterning Improves Reading and Mathematics

Research Findings: In each of 16 public school classrooms serving multiethnic low-income neighborhoods, 2 first graders were assigned to be taught patterning, 2 to be taught reading, 2 to be taught mathematics, and 2 to be taught social studies for 15-min sessions 3 days per week for 6 months. Assignment within each classroom was randomized. The children's mean age was 6 years, 5.19 months. Patterning instruction included instruction on symmetrical patterns, patterns with increasing numbers of elements, and patterns involving the rotation of an object through 6 or 8 positions. In May, the 120 children still available were tested on patterns, reading, and mathematics. Patterning instruction had large, fully mediated effects on both reading and mathematics. There were no significant differences on some individual scales, but on others children who received patterning instruction scored best, often by grade equivalents of 4 to 8 months. Extant explanations of the efficacy of patterning instruction are reviewed, and the potential importance and limitations of its role in early education are discussed. Practice or Policy: Patterning instruction should be extended to more complex patterns than the alternations currently used in elementary schools in order to produce important improvements in both reading and mathematics.     

Documentation and Universal Instructional Design: A Partnership Supporting Diverse Learners in Higher Education

Universal Instructional Design (UID), an approach to curriculum and pedagogy that promotes multiple means of access and expression in the classroom, allows instructors to better prepare diverse learners with twenty-first-century skill sets through nontraditional assignments. However, these nontraditional approaches can be difficult to assess. Videotaped, written, and visual documentation in a UID classroom allows higher education instructors to both formatively and summatively assess students. The authors explore four examples of various modes of documentation that allow them to capture snapshots of student learning as well as promote deeper reflection for themselves and their students on the learning process.     

How do professional learning communities aid and hamper professional learning of beginning teachers related to differentiated instruction?

Research has shown that adequate support from the school environment is necessary to help beginning teachers in applying differentiated instruction (DI), but how schools can aid in this process remains unclear. This qualitative study explores how professional learning communities (PLCs), an indicator of a supportive school environment, can enhance beginning teachers’ professional learning in DI. Furthermore, it examines how structural and cultural school conditions foster the development of PLCs in the schools’ organization. Semi-structured interviews were conducted with school leaders, special needs coordinators, and beginning teachers in primary schools. A comparative analysis was carried out in three schools with high (case A), medium (case B), and low (case C) levels of beginning teachers’ professional learning in DI, as assessed by changes in practice (i.e. teachers’ flexibility in adapting their classroom behaviour). The comparative analysis indicated that the three cases could be situated at different stages of PLC development. Case A had reached the mature stage, whereas case B was in the evolving stage and case C was still in the beginning stage of PLC development. Also, the analysis indicated that structural and cultural school conditions in the three cases were related to the different stages of PLC development. Finally, the results revealed that in the three cases, leadership of both the principal and special needs coordinator played a key role in the development of the structural and cultural school conditions.     

Craig Alternative School: A Case Study in Therapeutic Educational Intervention

Craig Alternative Middle/High School is an academic/therapeutic multi‐categorical exceptional education program for eighty‐five high risk male and female students who, because of their atypical behaviours, have not been successful in a less restrictive educational environment. The staff consisting of teachers, paraprofessionals, psychologists, social workers, probation officers and a psychiatrist, co‐ordinate the students' therapeutic, vocational and academic programs within a day school setting in an attempt to maximize positive behavioural change.     

Weak Ties in Networked Communities

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals–is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities.     

Boys Bonding: Same-sex friendship,the unconscious and heterosexual discourse

This article aims to explore some of the ways in which the cultural meanings and practices of gender, sexuality and relationships intersect with and are reworked in the same-sex friendships of children aged nine to eleven. Using material from an ethnographic study, it focuses on two boys, Ben and Karl, who identified themselves as best friends. The article argues that, while the boys clearly knew, positioned themselves in and deployed heterosexual discourse, their relationship to this was complex. In particular, they appeared to use it to distance themselves from the feminine and to build their friendship as a pleasurable, intimate and exciting space. The article uses psychoanalytic arguments to explore this material, tentatively suggesting that the boys' access to the cultural practice of 'best friendship' mobilised identifications that both reinforced conventional versions of heterosexual masculinity and questioned these. In particular, the article suggests that the boys' friendship may have involved 'over-inclusive' gender identifications - ones that indicate the existence of boyhood masculinities that are more capacious and flexible than those hegemonic in teenage and adolescent cultures.
