Digital play: a new classification

Abstract

This paper draws on an ESRC-funded study of play and creativity in preschool-aged children’s use of apps in the UK. The main objectives of the study were to collect information about access to and use of apps in the home, establish the most popular apps and identify the features of those apps that are successful in promoting play and creativity. A mixed-method approach was used to collect data, including video filming of children using the most popular apps. In identifying play types that emerged in the analysis of data, the team utilised an established taxonomy, which outlines sixteen play types. This taxonomy was reviewed and adapted to analyse data from the project relating to digital play. Through this process, an additional type of play, transgressive play, was identified and added to the taxonomy. The paper outlines the implications of the revised taxonomy for future studies of play.     

A General 3-Step Maximum Likelihood Approach to Estimate the Effects of Multiple Latent Categorical Variables on a Distal Outcome

The 3-step approach has been recently advocated over the simultaneous 1-step approach to model a distal outcome predicted by a latent categorical variable. We generalize the 3-step approach to situations where the distal outcome is predicted by multiple and possibly associated latent categorical variables. Although the simultaneous 1-step approach has been criticized, simulation studies have found that the performance of the two approaches is similar in most situations (Bakk & Vermunt, 2016). This is consistent with our findings for a 2-LV extension when all model assumptions are satisfied. Results also indicate that under various degrees of violation of the normality and conditional independence assumption for the distal outcome and indicators, both approaches are subject to bias but the 3-step approach is less sensitive. The differences in estimates using the two approaches are illustrated in an analysis of the effects of various childhood socioeconomic circumstances on body mass index at age 50.     

Migrants and minorities in Europe: implications for adult education and training policy

During the 1980s, individual member state government policy and that of the eu as a whole began to emphasise integration and multiculturalism, often in an attempt to diffuse tensions resulting from continued hardship and unemployment amongst minority communities. Although this signalled a move away from former assimilation approaches, there remains an ambiguity in policies which now advocate highly restrictive border controls on the one hand, and integration for those already ‘in’ on the other. Criticisms levelled at the eu's inability to acknowledge inequalities within migrant communities in the field of vocational training have recently increased, particularly in discussions about post‐1992 harmonisation and the benefit, if any, open borders will have on such communities. Current provision aiming to right these wrongs is primarily emphasising the insertion or re‐insertion of individuals into the labour market. Attempts have been made to link vocational training courses to labour market opportunities. Positive action strategies, positive career routes and job creation also play roles in this process. Funding however, especially from government sources, still tends to favour traditional providers, in spite of recent studies which have found that strategies emanating from the community ('consumer‐led') have a much more positive image amongst participants and tend to be more successful in their outcomes. Ideally, communities would set up their own projects, but failing this they can be empowered to do so by training professionals working in close collaboration with minority groups.     

Magic memories: young children's verbal recall after a 6-year delay

This report describes the first prospective study specifically designed to assess children's verbal memory for a unique event 6 years after it occurred. Forty-six 27- to 51-month-old children took part in a unique event and were interviewed about it twice, after 24-hr and 6-year delays. During the 6-year interview, 9 children verbally recalled the event, including 2 who were under 3 years old when the event occurred. This may be the most convincing evidence to date that such early experiences can be verbally recalled after long delays. These data have important implications for current theories of memory development and childhood amnesia and underscore some of the problems associated with evaluating the veracity of early memories under less controlled conditions.     

The accuracy of computational fluid dynamics analysis of the passive drag of a male swimmer

The aim of this study was to build an accurate computer-based model to study the water flow and drag force characteristics around and acting upon the human body while in a submerged streamlined position. Comparisons of total drag force were performed between an actual swimmer, a virtual computational fluid dynamics (CFD) model of the swimmer, and an actual mannequin based on the virtual model. Drag forces were determined for velocities between 1.5 m/s and 2.25 m/s (representative of the velocities demonstrated in elite competition). The drag forces calculated from the virtual model using CFD were found to be within 4% of the experimentally determined values for the mannequin. The mannequin drag was found to be 18% less than the drag of the swimmer at each velocity examined. This study has determined the accuracy of using CFD for the analysis of the hydrodynamics of swimming and has allowed for the improved understanding of the relative contributions of various forms of drag to the total drag force experienced by submerged swimmers.
