Predictive validity of the K-ABC for exceptional preschoolers

This 5-year follow-up study examined the predictive validity of the Kaufman Assessment Battery for Children (K-ABC) for 39 children identified during preschool as exhibiting language impairment (n = 10), behavior control deficits (n = 13), or normal language and behavioral development (n = 16). Mean age at follow-up was 9.75 years. The results generally supported the predictive validity of the K-ABC (p<.001). However, analyses by group indicated that the relationship between baseline K-ABC and follow-up K-ABC, language, and achievement measures for the language-impaired subjects was weak (p>.05). Although these results must be interpreted cautiously because of the small sample size, they suggest that for young children likely to be referred as at risk for future learning problems, the K-ABC may not be useful for prediction of later cognitive skills. Implications for practitioners are discussed.     

Linking corporate social responsibility in sport with community development: an added source of community value

This paper investigates the attributes of Corporate Social Responsibility (CSR) programmes in sport and their potential for sustainable community development. The gap between sport-related CSR and community development needs to be filled by shifting attention to the capacity building of communities. While the neoliberal foundations of CSR are recognized, it is essential to understand the ideological varieties driving CSR that can enable inclusiveness and collaboration in fostering community benefits of CSR programmes. The paper contributes to the literature on CSR in sport advancing the discourse, and sets the stage for a community-based framework for research: (1) related to sport as a tool for social change; (2) exploring the relationship of organizational motives, stakeholder engagement and CSR programme design/implementation; and (3) evaluating the perceived benefits of CSR programmes, and the extent to which these can help achieve sustainable community development.     

Acute fatigue negatively affects risk factors for injury in trained but not well-trained habitually shod runners when running barefoot

Introduction: Many factors may contribute to running-related injury. These include fatigue and footwear, the combination of which has rarely been studied, in particular with reference to barefoot running, recently advocated as a method to reduce injury risk. Methods: Twenty-two runners (12 well-trained and 10 trained) participated in a 10?km fatiguing trial. Knee and ankle joint kinematics and kinetics and electromyography were assessed during overground running in the barefoot and shod condition. This was performed pre- and post-fatigue using a motion capture system and force platforms. Results: Initial loading rate increased in the trained runners when barefoot but not shod. Shod knee stiffness increased in both groups after fatigue, whereas barefoot knee stiffness decreased only in the trained group. A reduction in barefoot bicep femoris pre-activation was found in both groups. During stance, a reduction in vastus lateralis and biceps femoris and an increase in tibialis anterior activity were found over time in both groups and conditions. Trained runners decreased gluteus medius and increased lateral gastrocnemius median frequency for both conditions after fatigue. Conclusion: When fatigued, gait adjustments in habitually shod runners may increase injury risk when running barefoot. Training status may be a risk factor for injury, as less-trained runners experience muscular fatigue changes that may compromise ground reaction force attenuation. Caution is recommended when transitioning to pure barefoot running.     

Are gait characteristics and ground reaction forces related to energy cost of running in elite Kenyan runners?

The aim of this study was to determine whether gait cycle characteristics are associated with running economy in elite Kenyan runners. Fifteen elite Kenyan male runners completed two constant-speed running sets on a treadmill (12 km ·h^?1 and 20 km ·h^?1). VO₂ and respiratory exchange ratio values were measured to calculate steady-state oxygen and energy cost of running. Gait cycle characteristics and ground contact forces were measured at each speed. Oxygen cost of running at different velocities was 192.2 ± 14.7 ml· kg^?1· km^?1 at 12 km· h^?1 and 184.8 ± 9.9 ml· kg^?1· km^?1 at 20 km· h^?1, which corresponded to a caloric cost of running of 0.94 ± 0.07 kcal ·kg^?1·km^?1 and 0.93 ± 0.07 kcal· kg^?1· km^?1. We found no significant correlations between oxygen and energy cost of running and biomechanical variables and ground reaction forces at either 12 or 20 km· h^?1. However, ground contact times were ~10.0% shorter (very large effect) than in previously published literature in elite runners at similar speeds, alongside an 8.9% lower oxygen cost (very large effect). These results provide evidence to hypothesise that the short ground contact times may contribute to the exceptional running economy of Kenyan runners.     

Suprasegmental Phonology Development and Reading Acquisition: A Longitudinal Study

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed.     

Grade 7 Students Reading Graphic Novels: ‘You Need To Do a Lot of Thinking’

A multifaceted, classroom‐based research project explored how developing Grade 7 students’ knowledge of literary and illustrative elements affects their understanding, interpretation and analysis of picturebooks and graphic novels, and their subsequent creation of their own print texts. Analysis of two sources of data, the students’ written responses to Amulet ( Kibuishi 2008 ), one of the graphic novels read and discussed during the study, and the students’ opinions about the knowledge that is required to read and understand a graphic novel, indicated how the instruction about various graphic novel conventions had impacted the students’ awareness of and knowledge about the structural design of these multimodal texts.
