A comparison of traditional and modified Summated-Heart-Rate-Zones models to measure internal training load in basketball players

The Summated-Heart-Rate-Zones training load (SHRZ TL) model is used to measure internal loading; however, a major limitation of this approach is the use of broad heart rate (HR) zones to quantify exercise intensity. Therefore, this study aimed to compare SHRZ TL outcomes derived using the traditional model and modified approaches using smaller HR zones. HR responses were monitored in 15 semi-professional basketball players during preparatory training to calculate SHRZ TL using the traditional approach with 10%HR_max zones (SHRZ₁₀) and modified approaches with 5%HR_max zones (SHRZ₅) and 2.5%HR_max zones (SHRZ_2.5). Significant (P < 0.001) differences were evident in SHRZ TL between SHRZ₁₀ (254.2 ± 41.7 AU) and SHRZ₅ (275.9 ± 43.3 AU, unclear, small) as well as SHRZ_2.5 (286.7 ± 44.3 AU, very likely, moderate). Use of SHRZ_2.5 provides novel insight regarding internal loading in basketball players and may carry greater sensitivity for detection of maladaptive and adaptive responses to training.     

Living with imperfect comparisons: The challenges and limitations of comparative paralympic sport policy research

In this article, the authors explores the challenges and limitations of conducting cross-comparative management/policy research in the Paralympic sporting domain. The comparative sport policy debate in able-bodied sport has emerged, in part, due to the increasing complexity, uncertainty, and competitive nature of high performance sport environments and a desire to understand why some countries are more successful than others at international sporting competition. The same issues and questions have also emerged within the Paralympic context. As a precursor to establishing a research agenda in this area, however, it was deemed important to begin to address the epistemological, methodological, and practical issues in comparative sport research. The analysis draws upon the broader sociological literature and examples from the Paralympic sporting context to identify and discuss the challenges and limitations of the comparative approach as well as recommendations for mitigating against them.     

Matjabala Mali’ Buku-Ruŋanmaram: implications for archives and access in Arnhem Land

This article traces the efforts of a research team led by the Yol?u elder and scholar, Neparr?a Gumbula, to investigate his people’s recorded history in the University of Sydney Archives. This research has identified some of the earliest photographic and written records of Yol?u life in Arnhem Land, Australia. Though consultations with the source communities of Mili?inbi (Milingimbi) and Galiwin’ku (Elcho Island), it has also determined appropriate ways of maintaining ongoing local access to these rare archived materials. The article contextualises this research within broader international initiatives to locate and provide access to other early ethnographic records from Arnhem Land. It considers the role of digital technologies in providing remote community access, and how various access protocols can be implemented to ensure appropriate use.     

Improving Achievement Using Digital Pedagogy: Impact of a Research Practice Partnership in New Zealand

This present study reports the impact of a research–practice partnership among nine collaborating schools and researchers in Auckland, New Zealand. The goals of the partnership were to refine digital instruction in ways that would result in improved learning processes and achievement. The partners employed a design-based research approach to iteratively develop and test changes to the pedagogy. Results indicate moderate to large effect sizes in writing, and small effect sizes in reading and mathematics. Results also indicate increasing effects over time in reading and writing, but not in mathematics. Educational effects included greater use of discussions by teachers and greater use of open-ended activity types. These outcomes are discussed in relation to features of the partnership as well as digital pedagogy.     

Spelling without phonology: A study of deaf and hearing children

To what extent does phonology play a role in spelling English words? The written responses of deaf students and groups of hearing children to five tasks were subjected to quantitative and qualitative analyses. The first three tasks were used to see if deaf students utilized phonology when they generated their own words and to compare their spelling performance with that of hearing subjects. The fourth and fifth tasks were designed to compare the spelling performance of deaf and hearing subjects when they were required to reproduce visually presented common words. Results showed that deaf students, who were chronologically much older, were not better spellers than hearing children from the fifth grade. Analysis of data revealed little evidence that the deaf students involved in the present study utilize phonology in spelling. Nor did word-specific visual memory for entire words appears to play a role in spelling by deaf students. Rote visual memory for letter patterns and sequences of letters within words, however, appears to play a role in the spelling by deaf students. It is concluded that sensitivity to the stochastic-dependent probabilities of letter sequences may aid spelling up to certain point but phonology is essential for spelling words whose structure is morphophonemically complex.

     

Participation in Dissection Affects Student Performance on Gross Anatomy Practical and Written Examinations: Results of a Four-Year Comparative Study

The role of human dissection in modern medical curricula has been a topic of intense debate. In part, this is because dissection can be time-consuming and curricular hours are being monitored more carefully. This has led some to question the efficacy and importance of dissection as a teaching method. While this topic has received considerable attention in the literature, the question of how dissection impacts learning has been difficult to evaluate in a real-world, high-stakes setting since participation in dissection is often one of many variables. In this study, this challenge was overcome due to a change in the curriculum of a Special Master Program (SMP) that permitted a comparison between two years of students that learned anatomy using prosection only and two years of students that participated in dissection laboratories. Since each class of SMP students took courses in the medical school, and the medical school anatomy curriculum was constant, medical student performance served as a control throughout the study period. Results demonstrate that SMP students who learned through prosection had lower performance on anatomy practical and written examinations compared to medical students. When the SMP program changed and students started participating in dissection, there were measurable improvements in both practical and written examinations. These findings provide evidence of dissection’s role in learning and applying anatomy knowledge both within and outside the gross anatomy laboratory.     

The Uses and Gratifications of Language in Social Media among the Indian Subcontinental Diaspora in the U.S.

This study examines the uses and gratifications of language in social media among the Indian subcontinental diaspora in the United States, based on data collected from an online survey of 535 adult immigrants following a snowballing technique. Results showed the use of native language is related to the use of home country media, while the use of English language is related to emotional adjustment. This study contributes to the literature on social media, community, and language preference by opening avenues for conducting further research on the usage of language in social media among the Indian subcontinental diaspora in the United States. The findings of this study contribute to an understanding of the influence of social media on language preference.     

Effects of two instructional sets on the validity of the Kaufman assessment battery for children–nonverbal scale with a group of severely hearing impaired children

The purpose of the study was to investigate the use of the Kaufman Assessment Battery for Children (K-ABC)–Nonverbal Scale with severely hearing impaired children. The K-ABC was administered to 49 children enrolled at a public residential school for the deaf. Test instructions were given to one group employing American sign language (ASL), plus pantomime and gestures, while the other group received pantomime and gesture (PG) instructions only. No significant difference was found between the two group mean nonverbal K-ABC scores. Also, neither group scored significantly different from the K-ABC norms. Both groups scored significantly lower than K-ABC norms on the Spatial Memory subtest. Significant correlations were found between the K-ABC and Wechsler Intelligence Scale for Children-Revised (WISC-R). A significant correlation also was found between K-ABC scores and Reading Comprehension. A post hoc analysis of data found that, regardless of the instructional set, the children scored significantly lower on the Nonverbal K-ABC than they did on the WISC-R Performance Scale. The study provides support for the appropriateness of the K-ABC for use with deaf children.
