Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.     

Representing creative labour and identity in Singaporean graphic novels: Sonny Liew and Troy Chin

ABSTRACT

This essay analyses two Singaporean graphic novels which represent the motivations and processes of creating and marketing cartoons, Sonny Liew's The Art of Charlie Chan Hock Chye (2015), a retrospective of the life and work of a fictional artist, and Troy Chin's ongoing autobiographical series, The Resident Tourist (begun in 2007). The analysis focuses on how Liew and Chin represent creative work and its relationship to Singaporean identity, focusing on how each negotiates one of the central contradictions of the creative industries in Singapore, the problem of how creativity can be conceptualised and practised within a society in which, for decades, pragmatism has been systematically valued and imagination devalued. There are three main ways in which both Liew and Chin construct, in very different ways, new creative worker and Singaporean identities which resonate with readers around the post-industrial world. The first is through subtle challenges to the Western, individualised ‘genius’ model of the creative worker. The second is through the creation of modes of address that encompass both Singaporean and non-Singaporean readers, and make all readers complicit in the project of constructing Singaporean identity. Third, both Liew and Chin reimagine the relationship between Singaporean and creative worker identities through simultaneously using and subverting the idea of national allegory.     

Culturally and Linguistically Relevant Readalouds

The teacher readaloud is an instructional tool established in its ability to foster children's language and literacy development. Increasing cultural and linguistic diversity and changing standards place pressure on teachers to provide literacy and language instruction relevant to children's everyday lives and learning. This article presents a framework for conducting culturally and linguistically relevant readalouds within two essential components, talk and text, in terms of developing cultural competence, maintaining high academic expectations, and fostering a critical stance. Particular attention is given to the interactive nature of these readalouds and how they can be used to promote children's active co-construction of textually-based meaning.     

Turning techno-savvy into info-savvy: authentically integrating information literacy into the college curriculum

It is no longer effective to provide information literacy instruction that is thought to be “good for” college students, but rather, instruction must focus on the learning styles and preferences of the target population. This case study reports a series of hands-on/minds-on information literacy activities that dissolve student's misconception that “techno-savvy” is synonymous with information literate. Careful and thorough instruction in the mining of popular Internet search engines for authoritative information was coupled with instruction in the use of traditional library resources. It was found that the college students studied possess a high need for clarity and a low tolerance for ambiguity, and therefore any activities assigned must be thoroughly, yet succinctly, described in order to achieve success. Combining traditional information literacy instruction with novel approaches appeals to the confidence in and reliance on Internet search engines that college students exhibit, while it moves this microcosm toward a higher level of information literacy and commitment to life long learning.
