Activity patterns of preschool-aged children at risk for obesity

BACKGROUND Although the prevalence of obesity in young children highlights the importance of early interventions to promote physical activity (PA), there are limited data on activity patterns in this age group. The purpose of this study is to describe activity patterns in preschool-aged children and explore differences by weight status. METHODS Analyses use baseline data from Healthy Homes/Healthy Kids- Preschool, a pilot obesity prevention trial of preschool-aged children overweight or at risk for overweight. A modified parent-reported version of the previous-day PA recall was used to summarize types of activity. Accelerometry was used to summarize daily and hourly activity patterns. RESULTS "Playing with toys" accounted for the largest proportion of a child's previous day, followed by "meals and snacks", and "chores". Accelerometry-measured daily time spent in sedentary behavior, light PA, and moderate-to-vigorous PA (MVPA) was 412, 247, and 69 minutes, respectively. Percent of hourly time spent in MVPA ranged from 3% to 13%, peaking in the late morning and evening hours. There were no statistically significant MVPA differences by weight status. CONCLUSIONS This study extends our understanding of activity types, amounts, and patterns in preschool-age children and warrants further exploration of differences in physical activity patterns by weight status.

A review of preschool children's physical activity and sedentary time using objective measures

CONTEXT: Identifying current physical activity levels and sedentary time of preschool children is important for informing government policy and community initiatives. This paper reviewed studies reporting on physical activity and time spent sedentary among preschool-aged children (2-5 years) using objective measures. EVIDENCE ACQUISITION: Databases were searched for studies published up to and including April 2013 that reported on, or enabled the calculation of, the proportion of time preschool children spent sedentary and in light- and moderate to vigorous-intensity physical activity. A total of 40 publications met the inclusion criteria for physical activity and 31 met the inclusion criteria for sedentary time. Objective measures included ActiGraph, Actiwatch, Actical, Actiheart, and RT3 accelerometers, direct observation, and Quantum XL telemetry heart rate monitoring. Data were analyzed in May 2013. EVIDENCE SYNTHESIS: Considerable variation in prevalence estimates existed. The proportion of time children spent sedentary ranged from 34% to 94%. The time spent in light-intensity physical activity and moderate to vigorous-intensity physical activity ranged from 4% to 33% and 2% to 41%, respectively. CONCLUSIONS: The considerable variation of prevalence estimates makes it difficult to determine the "true" prevalence of physical activity and sedentary time in preschool children. Future research should aim to reduce inconsistencies in the employed methodologies to better understand preschoolers' physical activity levels and sedentary behavior.

Prediction of activity type in preschool children using machine learning techniques

Objectives Recent research has shown that machine learning techniques can accurately predict activity classes from accelerometer data in adolescents and adults. The purpose of this study is to develop and test machine learning models for predicting activity type in preschool-aged children. Design Participants completed 12 standardised activity trials (TV, reading, tablet game, quiet play, art, treasure hunt, cleaning up, active game, obstacle course, bicycle riding) over two laboratory visits. Methods Eleven children aged 3–6 years (mean age = 4.8 ± 0.87; 55% girls) completed the activity trials while wearing an ActiGraph GT3X+ accelerometer on the right hip. Activities were categorised into five activity classes: sedentary activities, light activities, moderate to vigorous activities, walking, and running. A standard feed-forward Artificial Neural Network and a Deep Learning Ensemble Network were trained on features in the accelerometer data used in previous investigations (10th, 25th, 50th, 75th and 90th percentiles and the lag-one autocorrelation). Results Overall recognition accuracy for the standard feed forward Artificial Neural Network was 69.7%. Recognition accuracy for sedentary activities, light activities and games, moderate-to-vigorous activities, walking, and running was 82%, 79%, 64%, 36% and 46%, respectively. In comparison, overall recognition accuracy for the Deep Learning Ensemble Network was 82.6%. For sedentary activities, light activities and games, moderate-to-vigorous activities, walking, and running recognition accuracy was 84%, 91%, 79%, 73% and 73%, respectively. Conclusions Ensemble machine learning approaches such as Deep Learning Ensemble Network can accurately predict activity type from accelerometer data in preschool children.

A time for everything : reviewing an institution’s virtual learning environment

This paper outlines a review carried out at Queensland University of Technology (QUT) in 2013 to identify the extent to which the centrally supported virtual learning environment met current and future learning and teaching needs. A range of consultation and investigation activities occurred from May to November to encourage open stakeholder feedback as well as to allow for reflection on alternative digital technologies, systems and strategies. This resulted in the development of nine recommendations, which, following a planning phase, will commence being implemented from mid-2014.

Navigating pathways for academic staff development : implications for institutions and academic ranks

BACKGROUND As engineering schools adopt outcomes - focused learning approaches in response to government expectations and industry requirements of graduates capable of learning and applying knowledge in different contexts, university academics must be capable of developing and delivering programs that meet these requirements. Those academics are increasingly facing challenges in progressing their research and also acquiring different skill sets to meet the learning and teaching requirements. PURPOSE The goal of this study was to identify the types of development and support structures in place for academic staff, especially early career ones, and examine how the type of institution and the rank or role of the staff member affects these structures. DESIGN/METHOD We conducted semi - structured interviews with 21 individuals in a range of positions pertaining to teaching and learning in engineering education. Open coding was used to identify main themes from the guiding questions raised in the interviews and refined to address themes relevant to the development of institutional staff . The interview data was then analysed based on the type of institution and the rank/ role of the participant. RESULTS While development programs that focus on improving teaching and learning are available, the approach on using these types of programs differed based on staff perspective. Fewer academics, regardless of rank/role, had knowledge of support structures related to other areas of scholarship, e.g. disciplinary research, educational research, learning the institutional culture. The type of institution also impacted how they weighted and encouraged multiple forms of scholarship. We found that academic staff holding higher ranking positions, e.g. dean or associate dean, were not only concerned with the success of their respective programs, but also in how to promote other academic staff participation throughout the process. CONCLUSIONS The findings from this stud y extend the premise that developing effective academic staff ultimately leads to more effective institutions and successful graduates and accomplishing this requires staff buy - in at multiple stages of instructional and program development. Staff and administration developing approaches for educational innovation together (Besterfield - Sacre et al., 2014) and getting buy - in from all academic staff to invest in engineering education development will ultimately lead to more successful engineering graduates.

Learning about and taking action for the environment : child and teacher experiences in a preschool water education program

Water education and conservation programs have grown exponentially in Australian primary and secondary schools and, although early childhood services have been slower to respond to the challenges of sustainability, they are catching up fast. One early program targeted at preschools was the Water Aware Centre Program in northern New South Wales developed by the local water supply authority. This paper reports on a qualitative study of children’s and teachers’ experiences of the program in three preschools. The study’s aim was to identify program attributes and pedagogies that supported learning and action taking for water conservation, and to investigate if and how the program influenced children’s and teachers’practices. Data were collected through an interview with the program designer, conversations with child participants of the program, and a qualitative survey with early childhood staff. A three-step thematic analysis was conducted on the children’s and teachers’ data. Findings revealed that the program expanded children and teachers’ ideas about water conservation and increased their water conservation practices. The children were found to influence the water conservation practices of the adults around them, thus changing practices at school and at home.

A stakeholder analysis of one institution’s assuring learning experience – is the promise and the practice worth the price?

Universities around the world are rushing to implement assurance of learning policies and practices with varying degrees of success. One School investigated its own policy and practice development through the eyes of its key stakeholders to identify whether the practice was worth the price. Findings indicate that although the key stakeholders considered different needs and viewed their experiences differently, value did abound and was in the eye of the beholder.

Masculinity, sexuality, theology and child sexual abuse by personnel in Christian institutions

There growing recognition that a contributor to the repeat crises of child sexual abuse (CSA) by personnel in Christian institutions (PICIs), is the often gendered culture of Christian institutions themselves. This work explores theological discursive constructions of masculinity and sexuality and their implications for addressing CSA by PICIs. The perspectives discussed here are of PICIs who participated in a research project conducted in Australia. From these perspectives male gendered and sexual performance is constructed through discourse as both an explanation and solution to offending behaviour. Similarly, sexuality is viewed as God-given, heteronormative and legitimately expressed only within the bounds of marriage. This work draws on Foucault and feminist discourses as they relate to CSA by PICIs and institutional discourses. This work offers a perspective of PICIs that may not otherwise be heard in the common discourses of CSA in Christian Institutions.

In and out of preschool learning with iPads

In this chapter we describe and explain the ways we negotiated these same epistemological tensions and structural realities as we implemented the iPad loan component of the project reported in this book (hereafter: “iPad loan program”).Children who participated in the iPad loan program were able to take home one of the project iPads used in their preschool centre, much as they were able to take home books and puzzles. This component was one reflection of the ethos of “digital inclusion” that infused the project. As we noted in the introduction to this book, there is international recognition of the role that schools can play in ensuring all communities can participate in digital culture and the digital economy (e.g., European Commission, 2014; United States Government, 2013). Accordingly, we conducted the project in preschool centres where at least some groups of children were thought to enjoy less access to learning on digital platforms than others. Our goal was to put the iPad into the hands of children who might not otherwise have had access to it, while supporting teachers and parents in capitalising on the learning potential of the device for all the children. Centres nominated for the project by administrators in the preschool system all served communities that were either affected by poverty and/or diverse in language and culture.

Composing an email : social interaction in a preschool classroom

The chapter contributes understandings of digitally mediated interactions in early childhood classrooms. Ethnomethodological and conversation analysis approaches are used to analyse a video-recorded episode of children and teacher composing an email in a preschool classroom. In their talk we find how the teacher directs the children to what counts procedurally, such as the components of an email, and the teacher’s moral work in producing a culturally correct way form of personal communication. Such considerations of situated examples can encourage investigations of digital practices that extend beyond operational skills to broader understandings of digital practices as cultural and situated activities.

Teaching manufacturing engineering at tertiary institutions in conjunction with engineering design and engineering materials

Tertiary institutions now face serious challenges. Modern industry requires engineering graduates with strong knowledge of modern technologies, highly practical focus, management skills, ability to work individually and in a team, understanding of environmental issues and many other skills and graduate attributes. Institutions in the tertiary sector change courses and modify curriculum to reflect challenges of the modern industry and make engineering graduates better prepared for the “real world”. Queensland University of Technology in the recent years introduced an innovative structure of engineering courses with a common core for Bachelor of Engineering Mechanical, Infomechatronics and Medical, where manufacturing is taught in conjunction with engineering design and engineering materials. In this paper we discuss the innovative curriculum structure, teaching and learning approaches of coherent delivery of manufacturing in conjunction with engineering design and

Changing citizen confidence: Orientations towards political and social institutions in Australia, 1983-2010 [Review]

Since the early 1980s, when confidence in institutions was first measured in an Australian academic social survey, Australia - And the world - has faced many political, social and economic changes. From corporate scandals and company collapses, to unprecedented terrorist attacks, to major ongoing international conflicts, to changes in government and all manner of political machinations, to the global financial crisis and its aftermath. One consequence of such developments has been that many major political, social and economic institutions have come under intense pressure. Using survey research data, this paper investigates how public confidence in various Australian institutions and organisations has changed over time. The results are variable and in some instances surprising. Confidence in some institutions has remained high, and in some low, over an extended period of time. In other cases, confidence has varied quite markedly at different time points. As well as looking at trends in the level of public confidence in institutions, the paper examines different dimensions of confidence together with underpinning socio-political factors. It also discusses theoretical and practical implications of the data.

Pre-packaging preschool literacy: What drives early childhood teachers to use commercially produced phonics programs in prior to school settings

Language-rich environments are key to overall quality in early childhood settings, including frequent child–staff interactions around picture books and dramatic play. In a language-rich environment, explicit teaching of literacy concepts, such as phonics, is embedded in authentic and meaningful situations where alphabet letters and sounds are taught in a context meaningful to the child. Recent research, however, suggests that the use of commercial pre-packaged phonics programs (such as Letterland and Jolly Phonics) is widespread in prior to school settings in Sydney, Australia. Little is known about why early childhood teachers choose to use such programs with children aged five and under. In the present study, thematic analysis of data from interviews with five early childhood teachers using commercial phonics programs found that their reasons were pragmatic rather than pedagogical. Motivations included the idea that the programs reduced their workload, provided tangible evidence to parents of their child’s ‘school readiness’, and served as a marketing tool to attract parents. Further analysis found that the teachers were unable to articulate what phonics and phonological awareness are and how they are learnt in early childhood.

Financial institutions using social media – do consumers perceive value?

Purpose The purpose of this paper is to examine consumer perceptions of value of financial institutions using social media to interact with consumers; if overall perceived value predicts a consumer’s intention to adopt, and if intention predicts self-reported adoption of social media to interact with a financial institution; and if perceptions of value in using social media to interact with a financial institution changes over time. Design/methodology/approach Self-administered surveys were run at two time points; 2010 and 2014. Data were analyzed using multiple and mediated regressions, and t-tests. Comparisons are made between the two time points. Findings Perceived usefulness, economic value, and social value predicted overall perceived value, which in turn predicted a consumer’s intention to adopt social media to interact with a financial institution. At Time 2, adoption intention predicted self-reported usage behavior. Finally, there were significant differences between perceptions across Time 1 and 2. Research limitations/implications The implications of the research highlight the importance of overall perceived value in the role of adoption intention, and that at Time 2, adoption intention predicted self-reported adoption to read and share content. A reduction in perceptions of value and intentions from Time 1 to Time 2 could be explained by perceptions of technology insecurity. In future studies, the authors recommend examining inhibitors to adoption including hedonic value. Practical implications The findings suggest that consumers will use social media if the sector creates and clearly articulates consumer value from using social media. The sector also needs to address technology security perceptions to increase usage of social media. Originality/value This paper is one of the first to investigate the consumer’s perspective in social media adoption by financial institutions, by exploring the role of value in consumer adoption and usage of social media.
