Virtual stage sets in live performing arts (from the spectator to the spect-actor)

This paper studies the added value of VR to the art of stage setting through examples and experiments. It will also analyze the link between the audience and digital sets (VR, AR), from an aesthetic point of view as well as a practical one. It is important for us to succeed in creating a theatrical set which favors the spectator's presence for him to become a live performing spectator, and thus have a stronger link with the setting in the short as well as long run

A parent focused child obesity prevention intervention improves some mother obesity risk behaviors : the Melbourne infant program

BackgroundThe diets, physical activity and sedentary behavior levels of both children and adults in Australia are suboptimal. The family environment, as the first ecological niche of children, exerts an important influence on the onset of children\u27s habits. Parent modeling is one part of this environment and a logical focus for child obesity prevention initiatives. The focus on parent\u27s own behaviors provides a potential opportunity to decrease obesity risk behaviors in parents as well.ObjectiveTo assess the effect of a parent-focused early childhood obesity prevention intervention on first-time mothers\u27 diets, physical activity and TV viewing time.MethodsThe Melbourne InFANT Program is a cluster-randomized controlled trial which involved 542 mothers over their newborn\u27s first 18 months of life. The intervention focused on parenting skills and strategies, including parental modeling, and aimed to promote development of healthy child and parent behaviors from birth, including healthy diet, increased physical activity and reduced TV viewing time. Data regarding mothers\u27 diet (food frequency questionnaire), physical activity and TV viewing times (self-reported questionnaire) were collected using validated tools at both baseline and post-intervention. Four dietary patterns were derived at baseline using principal components analyses including frequencies of 55 food groups. Analysis of covariance was used to measure the impact of the intervention.ResultsThe scores of both the "High-energy snack and processed foods" and the "High-fat foods" dietary patterns decreased more in the intervention group: -0.22 ([MINUS SIGN]0.42;-0.02) and [MINUS SIGN]0.25 ([MINUS SIGN]0.50;-0.01), respectively. No other significant intervention vs. control effects were observed regarding total physical activity, TV viewing time, and the two other dietary patterns, i.e. "Fruits and vegetables" and "Cereals and sweet foods".ConclusionsThese findings suggest that supporting first-time mothers to promote healthy lifestyle behaviors in their infants impacts maternal dietary intakes positively. Further research needs to assess ways in which we might further enhance those lifestyle behaviors not impacted by the InFANT intervention

The effect of an early childhood obesity intervention on father\u27s obesity risk behaviors: the Melbourne InFANT program

BackgroundTo investigate the effect of an early childhood obesity prevention intervention, incorporating a parent modelling component, on fathers&rsquo; obesity risk-related behaviours.MethodsCluster randomized-controlled trial in the setting of pre-existing first-time parents groups organised by Maternal and Child Health Nurses in Victoria, Australia. Participants were 460 first-time fathers mean age&thinsp;=&thinsp;34.2 (s.d.4.90) years. Dietary pattern scores of fathers were derived using principal component analysis, total physical activity and total television viewing time were assessed at baseline (infant aged three to four months) and after 15 months.ResultsNo significant beneficial intervention effect was observed on fathers&rsquo; dietary pattern scores, total physical activity or total television viewing time.ConclusionDespite a strong focus on parent modelling (targeting parents own diet, physical activity and television viewing behaviours), and beneficial impact on mothers&rsquo; obesity risk behaviours, this intervention, with mothers as the point of contact, had no effect on fathers&rsquo; obesity risk-related behaviours. Based on the established links between children&rsquo;s obesity risk-related behaviors and that of their fathers, a need exists for research testing the effectiveness of interventions with a stronger engagement of fathers.<br /
