The internet of toys: a posthuman and multimodal analysis of connected play

Background: The study that is reported in this paper focuses on an exploration of the role and nature of play in young children’s use of toys that connect physical and digital domains. Purpose: The purpose of the paper is to explore the nature of the connections that are made in play that transverses physical and virtual domains. The paper draws on post-human theory in order to explain some of the complexity of the play that occurs in these contexts. Research Design: The research took place in the UK and the overall study consisted of four distinct stages: (i) A survey of 2000 parents of children aged 0-5, focusing on children’s access to and use of tablet apps; (ii) Case studies of pre-school children’s use of apps in six families (iii) Observations of children aged 3-5 in a school using apps (iv) Content and multimodal analysis of apps. The focus of this paper is on (ii), although some of the survey data from the first stage of the study are also shared in order to provide context. Data Collection and Analysis: The focus for this paper is the play of a threeyear old girl, Amy. In addition to ethnographic data constructed over a 2- month period (field notes, interviews, photographs and films), Amy’s mother collected data between the researchers’ visit by making films of her daughter’s use of apps. Amy also collected data herself by wearing a GoPro Chestcam. The data that informs the analysis in this paper is a film created by Amy (11.05 minutes) and a video filmed by Amy’s mother (5.21 minutes). Data were both inductively analyzed using multimodal (inter)action analysis and deductively analysed, utilizing a posthumanist approach. Findings: Amy’s play connected digital and non-digital components in complex ways. An app and related physical object that typify the Internet of Toys provided opportunities for Amy’s play to take place across physical and digital domains, and the inorganic objects embedded in the electronic toy and related app were an important element of this play, shaping Amy’s responses at times. However, Amy’s play was not always determined by the design of the electronic objects and she demonstrated agency within play episodes. There were multiple connections made across a variety of domains/ dimensions, which added to the complexity of the play. Conclusions/Recommendations: Young children’s play increasingly connects digital and non-digital domains and post-humanist theories can enhance understanding of how connections across these time/spaces are made

Statistical analysis plan for the OPTIMUM study: optimising immunisation using mixed schedules, an adaptive randomised controlled trial of a mixed whole-cell/acellular pertussis vaccine schedule

Objective: The purpose of this double-blind, randomised, controlled trial is to compare allergic outcomes in children following vaccination with acellular pertussis (aP) antigen (standard of care in Australia) given at 2 months of age versus whole cell pertussis (wP) in the infant vaccine schedule. Participants: Up to 3000 Australian infants 6 to <12 weeks of age born ≥32 weeks gestation. Interventions: The intervention is a wP containing vaccine as the first scheduled pertussis vaccine dose instead of an aP containing vaccine. Outcomes: The primary outcome is a binary indicator of history of IgE-mediated food allergy at the age of 12 months confirmed, where necessary, with an oral food challenge before 18 months of age. Secondary outcomes include (1) history of parent-reported clinician-diagnosed new onset of atopic dermatitis by 6 or 12 months of age with a positive skin prick test to any allergen before 12 months of age, (2) geometric mean concentration in pertussis toxin-specific IgG before and 21 to 35 days after a booster dose of aP at 18 months of age, and (3) sensitisation to at least one allergen by 12 months of age. Results: Operating characteristics of trial decision rules were evaluated by trial simulation. The selected rules for success and futility approximately maintain type I error of 0.05 and achieved power 0.85 for a reduction in the primary outcome from 10% in the control group to 7% in the intervention group. Discussion: A detailed, prospective statistical analysis plan (SAP) is presented for this Bayesian adaptive design. The plan was written by the trial statistician and details the study design, pre-specified adaptive elements, decision thresholds, statistical methods, and the simulations used to evaluate the operating characteristics of the trial. Application of this SAP will minimise bias and supports transparent and reproducible research. Trial registration: Australia & New Zealand Clinical Trials Registry, ACTRN12617000065392.

The impact of parent-created motivational climate on adolescent athletes' perceptions of physical self-concept

This is a preliminary version of this article. The official published version can be obtained from the link below.Grounded in expectancy-value model (Eccles, 1993) and achievement goal theory (Nicholls, 1989), this study examined the perceived parental climate and its impact on athletes' perceptions of competence and ability. Hierarchical regression analyses with a sample of 237 British adolescent athletes revealed that mothers and fathers' task- and ego-involving climate predicted their son's physical self-concept; the father in particular is the strongest influence in shaping a son's physical self-concept positively and negatively. It was also found that the self-concept of the young adolescent athlete is more strongly affected by the perceived parental-created motivational climate (both task and ego) than the older adolescent athlete's self-concept. These findings support the expectancy-value model assumptions related to the role of parents as important socializing agents, the existence of gender-stereotyping, and the heavy reliance younger children place on parents' feedback

Book review of perspectives on organizational fit by Cheri Ostroff and Timothy A. Judge (Editors)

From the first moment you set your eyes on this book, you are aware that it is a serious endeavor. Edited by two of the most published people in the field and sporting an imposing black and lime green dust cover containing an image of a swarm of black skull-headed moths, it contains chapters written by virtually all of “the good and the great” of the field. A flick through the pages reveals hundreds of pages of narrow margins and dense typescript interspersed with equations and three-dimensional graphs. This is a book that demands attention

Implementation and second-year impacts for New Deal 25 Plus customers in the UK Employment Retention and Advancement (ERA) demonstration

This report presents findings on the implementation and effectiveness of Britain's Employment Retention and Advancement (ERA) demonstration programme for New Deal 25 Plus customers (ND25 Plus) two years after entering the programme. The effectiveness of this programme is being evaluated using a random assignment research design. Over 16,000 people were randomly assigned onto the programme, making this study one of the largest randomised social policy trials ever undertaken in Britain. The analysis relies heavily on data from two waves of a longitudinal customer survey administered at 12 and 24 months respectively, following each individual's date of random assignment (when they entered the study). The survey respondents (around 6,000) are a representative sub-sample of the full sample of ND25 Plus customers enrolled in the study. The analysis also used data on employment, earnings and benefits receipt from administrative records for the entire sample. To provide a richer understanding of the Jobcentre Plus offices' experience of implementing ERA and customers experiences of ERA, the analysis also uses qualitative research involving in-depth interviews with ERA staff and customers

Shapes of the 192,190^{192,190}Pb ground states from beta decay studies using the total absorption technique

The beta decay of $^{192,190}$Pb has been studied using the total absorption technique at the ISOLDE(CERN) facility. The beta-decay strength deduced from the measurements, combined with QRPA theoretical calculations, allow us to infer that the ground states of the $^{192,190}$Pb isotopes are spherical. These results represent the first application of the shape determination method using the total absorption technique for heavy nuclei and in a region where there is considerable interest in nuclear shapes and shape effects

Smartphone Apps for Measuring Human Health and Climate Change Co-Benefits: A Comparison and Quality Rating of Available Apps.

BACKGROUND: Climate change and the burden of noncommunicable diseases are major global challenges. Opportunities exist to investigate health and climate change co-benefits through a shift from motorized to active transport (walking and cycling) and a shift in dietary patterns away from a globalized diet to reduced consumption of meat and energy dense foods. Given the ubiquitous use and proliferation of smartphone apps, an opportunity exists to use this technology to capture individual travel and dietary behavior and the associated impact on the environment and health. OBJECTIVE: The objective of the study is to identify, describe the features, and rate the quality of existing smartphone apps which capture personal travel and dietary behavior and simultaneously estimate the carbon cost and potential health consequences of these actions. METHODS: The Google Play and Apple App Stores were searched between October 19 and November 6, 2015, and a secondary Google search using the apps filter was conducted between August 8 and September 18, 2016. Eligible apps were required to estimate the carbon cost of personal behaviors with the potential to include features to maximize health outcomes. The quality of included apps was assessed by 2 researchers using the Mobile Application Rating Scale (MARS). RESULTS: Out of 7213 results, 40 apps were identified and rated. Multiple travel-related apps were identified, however no apps solely focused on the carbon impact or health consequences of dietary behavior. None of the rated apps provided sufficient information on the health consequences of travel and dietary behavior. Some apps included features to maximize participant engagement and encourage behavior change towards reduced greenhouse gas emissions. Most apps were rated as acceptable quality as determined by the MARS; 1 was of poor quality and 10 apps were of good quality. Interrater reliability of the 2 evaluators was excellent (ICC=0.94, 95% CI 0.87-0.97). CONCLUSIONS: Existing apps capturing travel and dietary behavior and the associated health and environmental impact are of mixed quality. Most apps do not include all desirable features or provide sufficient health information. Further research is needed to determine the potential of smartphone apps to evoke behavior change resulting in climate change and health co-benefits

Pinning of a solid--liquid--vapour interface by stripes of obstacles

We use a macroscopic Hamiltonian approach to study the pinning of a solid--liquid--vapour contact line on an array of equidistant stripes of obstacles perpendicular to the liquid. We propose an estimate of the density of pinning stripes for which collective pinning of the contact line happens. This estimate is shown to be in good agreement with Langevin equation simulation of the macroscopic Hamiltonian. Finally we introduce a 2--dimensional mean field theory which for small strength of the pinning stripes and for small capillary length gives an excellent description of the averaged height of the contact line.Comment: Plain tex, 12 pages, 3 figures available upon reques
