Running to behavior change

Levels of overweight and obese individuals have been seen as rising across the globe. This has caused concerns with regard to how active individuals are and realization that a high percentage of the population do not meet the weekly requirement of physical activity. Current focus has been on the capabilities that new technologies can offer as an intervention technique. This paper offers an initial investigation into one such technology, namely the iPod Nike+ kit, which acts as a tracker for running behaviors. This scoping study was conducted via a questionnaire and analysis of customer reviews. Participants were assessed on their stage of change for physical activity behavior, based on the Transtheoretical Model of Change (TTM), before and after using the technology. The results from this study showed that the technology was received positively from those who used it and the predominant outcome was that individuals were more enthusiastic about running

What difference does dance make? Critical conversations across dance, physical activity and public health

Critical conversations concerning if and how dance ‘fits’ within current (dominant) discourse across physical activity (PA), public health (PH) and sport policy are presented here in the form of commentaries from a ‘collective’ research base and individual ‘worldviews’ that includes the director of an established community-based dance organisation, a local authority PH commissioner and three academic researchers (a sociologist, cultural geographer and technologist). Dynamic dialogue between all parties has been encouraged throughout the research process (January–December 2015). From our viewpoints, discursive differences and occasional disciplinary dilemmas are regarded as potentially knowledge producing. We share transcribed parts of our critical conversations to illustrate how evaluating dance as PA represents opportunities for challenging if not disrupting some discursive terrain, whilst concurrently being somewhat constrained by that terrain. Our broader research remit contributes to ongoing debates surrounding ‘what works’ in relation to PA. Our dynamic interactions are thus constitutive of and productive within wider circuits or discourses of policy and provision. Paradigmatic rivalry or epistemological ‘tensions’ may well be hindering attempts to demonstrate that dance does have positive impacts on health. Acknowledgement and engagement with these tensions can arguably inform policy and practice in effective and meaningful ways and contribute further to debates regarding an evidence base seeking to ‘prove’ the benefits of activity-based programmes and interventions as we look across PA, PH and sport

Changing eating behaviors through a cooking-based website for the whole family

This paper reports on the results of a study investigating how nutritional eating behaviors can be improved by presenting a cooking-based website for parents to use with their children. Participants' eating behaviors were closely monitored via questionnaires and food diaries. Results show that over the course of the study, children's willingness to consume fruit and vegetables had improved and they enjoyed participating in food preparation. This was supported by the participants' food diaries, which showed a statistically significant increase in the number of portions of fruit and vegetables consumed by both children and parents. An attempt was made to place participants in a stage of change before and after the study (Transtheoretical Model). This was flawed, however, due to inaccurate measurements and the short study duration. Overall, this study provides support for the use of educational websites, in particular a cooking website, to improve nutritional eating behaviors in children. © 2013 Springer-Verlag Berlin Heidelberg

Participatory Methods to Engage Autistic People in the Design of Digital Technology: A Systematic Literature Review

Purpose Many technology designers strive to involve end users in the design process, aiming to produce better outcomes. However, designers may struggle to engage autistic users effectively due to a lack of understanding of autistic characteristics and preferences. This systematic literature review aimed to identify how autistic adolescents and adults can best be engaged in effective participatory design activities. Methods Seven databases were searched for articles reporting technology design involving autistic people, returning 276 results. Using the PRISMA approach, 258 were excluded due to not meeting the inclusion criteria. The remaining 18 articles were then quality assessed. Results A thematic analysis revealed five core themes: (1) Engagement: the importance of investment in, and ownership of, the design process to create engagement, (2) Relationships: building relationships through collaboration and careful facilitation, (3) Skills development: the development of personal skills such as teamwork, design and self-advocacy in order to grow confidence, (4) Structure: providing context and structure to make the design experience feel safe and predictable, and (5) Support: the importance of support and consideration of individual needs as well as discouraging negative behaviours. Conclusion Valuing participants as equal partners in design emerged as an, arguably, universal principle. The specific needs and preferences of autistic people must be understood and respected by designers. This goes beyond obvious accommodations such as providing a quiet and safe environment, and requires a deeper, more personal engagement with the individuals and their interests. We provide tangible recommendations for increasing engagement and aiding the design process

A modified beam-to-earth transformation to measure short-wavelength internal waves with an acoustic Doppler current profiler

Author Posting. © American Meteorological Society 2005. This article is posted here by permission of American Meteorological Society for personal use, not for redistribution. The definitive version was published in Journal of Atmospheric and Oceanic Technology 22 (2005): 583–591, doi:10.1175/JTECH1731.1.The algorithm used to transform velocity signals from beam coordinates to earth coordinates in an acoustic Doppler current profiler (ADCP) relies on the assumption that the currents are uniform over the horizontal distance separating the beams. This condition may be violated by (nonlinear) internal waves, which can have wavelengths as small as 100–200 m. In this case, the standard algorithm combines velocities measured at different phases of a wave and produces horizontal velocities that increasingly differ from true velocities with distance from the ADCP. Observations made in Massachusetts Bay show that currents measured with a bottom-mounted upward-looking ADCP during periods when short-wavelength internal waves are present differ significantly from currents measured by point current meters, except very close to the instrument. These periods are flagged with high error velocities by the standard ADCP algorithm. In this paper measurements from the four spatially diverging beams and the backscatter intensity signal are used to calculate the propagation direction and celerity of the internal waves. Once this information is known, a modified beam-to-earth transformation that combines appropriately lagged beam measurements can be used to obtain current estimates in earth coordinates that compare well with pointwise measurements.A.

Fusarium oxysporum f. sp. cubense tropical race 4 (TR4) is reported for the first time in northern Queensland, the centre of Australia’s commercial banana production. The identity of the pathogen was confirmed by vegetative compatibility group testing, TR4 specific PCR tests and sequencing. Although presently confined to a single property, the disease poses a serious threat to Australia’s banana industry

NMReDATA, a standard to report the NMR assignment and parameters of organic compounds

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. Open access articleEven though NMR has found countless applications in the field of small molecule characterization, there is no standard file for the NMR data relevant to structure characterization of small molecules. A file format is introduced to associate the NMR parameters extracted from 1D and 2D spectra of organic compounds to the assigned chemical structure. These NMR parameters, which we shall call NMReDATA, include chemical shift values, signal integrals, intensities, multiplicities, scalar coupling constants, lists of 2D correlations, relaxation times and diffusion rates. The file format is an extension of the existing SDF (Structure Data Format), which is compatible with the commonly used MOL format. The association of an NMReDATA file with the raw and spectral data from which it originates constitutes an NMR record. This format is easily readable by humans and computers and provides a simple and efficient way for disseminating results of structural chemistry investigations, automating the verification of published result, and for assisting the constitution of highly needed open-source structural databases
