Effect of team rank and player classification on activity profiles of elite wheelchair rugby players     

James M. Rhodes  Barry S. Mason  Laurie A. Malone 《Journal of sports sciences》2015,33(19):2070-2078

The aim of the current study was to establish which indicators of mobility are associated with successful wheelchair rugby performance and determine whether these indicators differed across classification. Data were collected from 11 international teams during 30 matches (353 match observations) using a radio-frequency-based, indoor tracking system across two tournaments. Players (n = 111) were first grouped by team rank as determined by their International Wheelchair Rugby Federation (IWRF) world ranking (LOW, MID, HIGH) and then into one of four groups based on their IWRF classification: Group I (0.5), Group II (1.0–1.5), Group III (2.0–2.5) and Group IV (3.0–3.5). The volume of activity (relative distance and mean speed), peak speed and time spent within classification-specific arbitrary speed zones were calculated for each individual. Although no differences were identified in the volume of activity, playing time was significantly reduced in LOW (34:51 ± 8:35) compared to MID (48:54 ± 0:51) and HIGH (45:38 ± 9:53), which was further supported by the greater number of substitutions performed by LOW. HIGH achieved greater peak speeds (3.55 ± 0.40 m · sˉ¹) than LOW (3.27 ± 0.42 m · sˉ¹) and MID (3.45 ± 0.41 m · sˉ¹). Peak speed was further shown to be classification-dependent (P ≤ 0.005), whereby HIGH Groups III and IV players achieved greater peak speeds than LOW and MID. The time spent performing high-intensity activities was also greater in HIGH compared to LOW and MID, whilst further influenced by classification (P ≤ 0.0005). To conclude, peak speed and the ability to perform a greater number of high-intensity activities were associated with successful performance in wheelchair rugby.  相似文献   

Assessment of Classroom Environments in Reformed Calculus Education     

Joiner  Keith F.  Malone  John A.  Haimes  David H. 《Learning Environments Research》2002,5(1):51-76

Research was conducted to determine if current reforms in calculus education are more inclusive of students of different genders, personalities, attributional beliefs, mathematical abilities, and computer attitudes. Two types of calculus reform are examined: a computer-assisted, student-centred and inductive reform based on the Calculus and Maple (C&M) package; and a teacher-only, teacher-centred and deductive reform. Both methods emphasise student participation in the learning and employ collaborative-learning groups mixed by ability and the assessed sociometric measures, but not mixed by gender. The classroom environments of the reform classes were assessed qualitatively using free-form surveys, interviews and classroom observations, and assessed quantitatively using the College and University Classroom Environment Inventory (CUCEI). The classroom environment of reform classes was compared qualitatively to the normal lecture environment. Students assessed the classroom environment as being significantly less favourable than preferred, confirming general dissatisfaction with socio-emotional aspects of university classes, even when adopting modern educational reforms. Differences in the actual and preferred classroom environments were observed in all class sub-divisions (i.e. gender, personality) and across all environment scales of the CUCEI. The research illustrates the psychosocial diversity of reforms for university classrooms and the desirability of evaluating such reforms using a learning environment inventory as well as conventional qualitative measures.  相似文献   

Puberty Predicts Approach But Not Avoidance on the Iowa Gambling Task in a Multinational Sample          下载免费PDF全文

According to the dual systems model of adolescent risk taking, sensation seeking and impulse control follow different developmental trajectories across adolescence and are governed by two different brain systems. The authors tested whether different underlying processes also drive age differences in reward approach and cost avoidance. Using a modified Iowa Gambling Task in a multinational, cross‐sectional sample of 3,234 adolescents (ages 9–17; M = 12.87, SD = 2.36), pubertal maturation, but not age, predicted reward approach, mediated through higher sensation seeking. In contrast, age, but not pubertal maturation, predicted increased cost avoidance, mediated through greater impulse control. These findings add to evidence that adolescent behavior is best understood as the product of two interacting, but independently developing, brain systems.  相似文献   

Variability in the Play of Preschoolers with Cognitive Delays Across Different Toy Sets     

D. Michael Malone  John Langone 《International Journal of Disability, Development & Education》1998,45(2):127-142

The variability in the play of 30 preschool children with cognitive delays associated with different toy sets was examined. Twelve dependent variables representing categorical and sequential play were coded from videotaped home‐based independent play sessions using a continuous 15 s interval coding procedure. Analyses of toy effect were conducted both across and within toy sets. Sex by toy set interaction effects emerged for exploration, pretend, ordered multischeme sequences, and global play sophistication. Main effects across toy sets were noted for nonplay, functional play, construction, overall proportion of play, time spent sequencing activities, and length of play sequences. The pattern of play observed within each toy set was strikingly similar across each of the three toy sets. The implications of these results for practice are discussed.  相似文献   

The Production Effect Improves Memory in 7- to 10-Year-Old Children     

Verena E. Pritchard  Michelle Heron-Delaney  Stephanie A. Malone  Colin M. MacLeod 《Child development》2020,91(3):901-913

The production effect—whereby reading words aloud improves memory for those words relative to reading them silently—was investigated in two experiments with 7- to 10-year-old children residing in Brisbane, Australia. Experiment 1 (n = 41) involved familiar printed words, with words read aloud or silently appearing either in mixed- or blocked-list formats in a within-subject design. Recognition for words read aloud was better than for those read silently, an effect consistent across both list formats. These results were confirmed in Experiment 2 (n = 40) using longer lists of printed novel nonwords. Final analyses indicated that the production effect was comparable for words and nonwords. Findings are discussed in relation to the distinctiveness account and the use of production as a mnemonic in children.  相似文献   

A snapshot of multicultural training in school psychology     

Celeste M. Malone  Kareem Z. Ishmail 《Psychology in the schools》2020,57(7):1022-1039

With the rapidly increasing racial and ethnic diversity of the school-aged population, school psychologists must be properly trained to engage in culturally competent practice; however, little is known about how school psychology programs prepare their trainees to serve diverse populations. The purpose of this study was to update Rogers et al.'s study on multicultural training by examining the extent to which school psychology programs use multicultural training recommendations noted in the literature. Thirty-eight school psychology program coordinators completed the Multicultural Environmental Inventory-Revised (MEI) to assess their perceptions of their program's multicultural environment. Participants were also asked about their training in multicultural and diversity issues and how their program conducts multicultural training. Findings suggest that programs most frequently used the integration and separate course models for multicultural training along with clinical experiences serving diverse students. In addition, multicultural coursework was associated with higher scores on the MEI Curriculum and MEI Research subscales. With regard to program environment, the percentage of racial and ethnic minoritized (REM) students was positively correlated to the percentage of REM faculty and the number of required multicultural courses. However, programs lacked specific strategies to recruit and retain diverse students. Findings and implications for training programs are discussed.  相似文献   

Exercise intensity during wheelchair rugby training     

J. P. Barfield  Laurie A. Malone  Crystal Arbo  Alan P. Jung 《Journal of sports sciences》2013,31(4):389-398

Abstract

The purpose of this study was to determine the ability of individuals with a cervical spinal cord injury to achieve and sustain a cardiorespiratory training intensity during wheelchair rugby. Nine wheelchair rugby players completed a continuous peak exercise test on a SciFit Pro I arm ergometer with stage increases each minute to determine peak heart rate and power output. Approximately one week after peak exercise testing, heart rate was recorded (every 5 s) during three regularly scheduled rugby training sessions. Data were analysed to determine the number of continuous minutes that participants spent above 70% of heart rate reserve under various rugby training activities. The percent of time spent at or above 70% heart rate reserve varied across participants and conditions. Continuous pushing was the least variable training condition among participants with the sample averaging greater than 73% of time above the target heart rate. Scrimmage training was highly variable across participants with a range of 0% to 98% of time above the criterion. Results of this study indicate that wheelchair rugby training enables some participants to reach a training intensity associated with improved cardiorespiratory fitness, and that the type (or kind) of training activity dictates the extent to which individuals sustain such a threshold.  相似文献   

Tackling a lingering infirmity: On the nature and warrant of action research in education     

Padraig Hogan  Anthony Malone 《British Educational Research Journal》2023,49(3):439-454

The BERA initiative on promoting Close-to-Practice (CtP) research raises new challenges for action research, particularly as uncertainties about the standing and rigour of action research were expressed in the report of the education panel for the 2015 Research Excellence Framework (REF) in the United Kingdom. The work of tackling these challenges is essential in advancing CtP research, and it discloses, in turn, new possibilities. In this paper we review some pioneering developments in action research and analyse the difficulties it has experienced in securing parity of standing with other forms of research. We argue that action research is more than, and sometimes other than, a social science. We seek to show that if action research is to be recognised by credentials that are its own, and judged by criteria that are proper to it, not only does it lose any lower standing. Rather, it becomes a major pathway, with deep roots in the critical traditions of Western practical philosophy, through which the defining purposes of education itself, as a distinctive human practice, are ascertained and affirmed, pursued and appraised.  相似文献   

A hospital-based patient and family education center: if you build it, will they come?     

Calabretta N  Cavanaugh S  Malone M  Swartz BJ 《Medical reference services quarterly》2011,30(1):19-30

Librarians located in a 560-bed, inner city academic medical center with 25,000?+ admissions per year planned and opened a Patient and Family Education Center (PFEC) in the lobby of a new patient care pavilion. A review of use in the first 19 months revealed that expected needs were being met while a variety of unexpected needs were identified. Ongoing use continues to be monitored by a detailed log of patron visits maintained by library staff. This article describes the evolution of the Patient and Family Education Center, outreach to the hospital community, and plans for the future.  相似文献
