Comparison of Indirect Calorimetry- and Accelerometry-Based Energy Expenditure during Object Project Skill Performance

This study compared the energy expenditure (EE) levels during object projection skill performance (OPSP) as assessed by indirect calorimetry and accelerometry. Thirty-four adults (female n = 18) aged 18–30 (23.5 ± 2.5 years) performed three, 9-min sessions of kicking, over-arm throwing, and striking performed at 6-, 12-, and 30-sec intervals. EE was estimated (METS) using indirect calorimetry (COSMED K4b2) and hip-worn accelerometry (ActiGraph GT3X+). EE using indirect calorimetry demonstrated moderate-intensity physical activity (3.4 ± 0.7 METS––30-sec interval, 5.8 ± 1.2 METS––12-sec interval) to vigorous intensity physical activity (8.3 ± 1.7 METS––6-sec interval). However, accelerometry predicted EE suggested only light-intensity physical activity (1.7 ± 0.2 METS––30-sec interval, 2.2 ± 0.4 METS––12-sec interval, 2.7 ± 0.6 METS––6-sec interval). Hip-worn, ActiGraph GT3X+ accelerometers do not adequately capture physical activity intensity levels during OPSP, regardless of differences in skill performance intervals.     

A Cognitive Model for Examining Teachers' Instructional Practice in Mathematics: A Guide for Facilitating Teacher Reflection

The purpose of this exploratory study was to develop a model to examine teachers' instructional practice in secondary school mathematics in relationship to their underlying cognitions. The instructional practice and cognitions of seven experienced and seven beginning teachers of secondary school mathematics were examined as a basis for the creation of the model. To examine instructional practice a Phase-Dimension Framework for the Examination of Mathematics Teaching was developed. Data were obtained through observations, lesson plans, videotapes and audiotapes of structured interviews during the course of one semester. The value of the model lies in its usefulness as a guide for enabling teachers to reflect on their instructional practice and underlying cognitions in a structured, comprehensive manner.This revised version was published online in September 2005 with corrections to the Cover Date.     

Process and progress: working with born-digital material in the Wendy Cope Archive at the British Library

This article considers the processing of the born-digital archive of the English poet Wendy Cope, deposited at the British Library in 2011. Using the Cope Archive as a template, the authors set out a six-part workflow to acquire, preserve, process and make it accessible. The Cope Archive, which contains several types of digital media, presented various problems. The authors, however, were able to successfully apply their workflow and outline the various software and methods used at each stage. They conclude that, though each born-digital archive presents a unique set of issues, the proposed workflow is a successful framework that would be applicable to most.     

Student views on transition to higher education in Ireland: Challenges,impacts and suggestions

This paper examines students’ perspectives on the main transitional challenges experienced when commencing higher education. It explores which students are most affected by the transition and is the first paper to provide an overview of student recommendations to help improve the transition in an Irish context. The study involves large‐scale surveys and focus groups across four higher education institutions and explores a range of transitional challenges (including academic, social and course‐specific aspects). Over 1,100 student suggestions to improve transition are analysed and many of these recommendations could be easily implemented beyond Ireland. Ten overall recommendations are made which include, among others, specific supports for mature students and those with longer commuting distances, course‐specific introductory skills modules to be given by current students, a first year ‘starter’ pack with course‐specific orientation materials, and the introduction of a student‐shadowing programme for prospective students.     

Arts enrichment and school readiness for children at risk

Arts enrichment provides varied channels for acquiring school readiness skills and may offer important educational opportunities for students from diverse backgrounds and with diverse needs. Study 1 examined achievement within an arts enrichment preschool that served low-income children. Results indicated that students practiced school readiness skills through early learning, music, creative movement, and visual arts classes. Students who attended the preschool for 2 years demonstrated higher achievement than those who attended for 1 year, suggesting that maturation alone did not account for achievement gains. Across 2 years of program attendance and four time points of assessment, students improved in school readiness skills, and there were no significant effects of race/ethnicity or developmental level on achievement growth. Study 2 compared students attending the arts enrichment preschool to those attending a nearby alternative on a measure of receptive vocabulary that has been found to predict school success. At the end of 1 year of attendance, students in the arts program showed greater receptive vocabulary than those at the comparison preschool. Results suggest that arts enrichment may advance educational outcomes for children at risk.     

The status model of racial identity development in African American adolescents: evidence of structure, trajectories, and well-being

Although the identity formation model is widely used to assess adolescent ethnic identity development, the model propositions have rarely been tested. The existence of the identity statuses (diffuse, foreclosed, moratorium, achieved), the proposed developmental trajectories, and whether youth in the achieved status report higher levels of psychological well-being were examined among a longitudinal sample of 224 African American adolescents, aged 11-17. Cluster analyses were used to create 4 identity statuses consistent with the theoretical model at both time points. The findings indicate that some adolescents progressed, while others regressed or remained constant across time periods. Lastly, the results generally support the assumption that individuals in the achieved status had the highest levels of psychological well-being at both time periods.
