Physical prototypes in cross-functional team collaboration : a study of the Model-T2 concept car project

Virtual and physical prototypes play a significant role in the design of artifacts. This is particularly true in cross-functional team collaboration, where diverse disciplines come together to contribute to the concept, design and development of an artifact. While the role of prototyping in design and cross-functional collaboration has been widely studied independently, little is known of the role that physical prototypes play during cross-functional team collaboration. This paper reports on a study of virtual and physical prototyping strategies used by a cross-functional team comprising engineers and designers working on a concept car project. The paper provides a background of the collaborative design process and details the role of physical prototyping methods during the design of the concept car.

Homework through the eyes of children : what does visual ethnography invite us to see?

Whilst the notion of children’s rights and an entitlement to express their views and participate as global citizens is threaded throughout the international policy field, children’s perspectives on the near ubiquitous practice of homework, and its effects on their daily lives and learner subjectivities, remain under-researched. Drawing on the Bourdieuian concepts of practice, habitus, capital and field, this article develops a cross-cultural analysis of homework practices in Australia, Denmark and Britain to make visible the embodied habitus and agentic possibilities shaping the reproduction of educational advantage and disadvantage for variously located students. Using video data generated by children in primary schools, the article explores children’s visual representations of their compliance and resistance to homework’s regulatory functions. It demonstrates the affordances of visual ethnographic methods as a form of participatory research with children which foregrounds students’ experiences and opinions and makes visible the inclusionary and exclusionary effects of homework on children in diverse socio-cultural settings.

Anxiety is more common in children with asthma

Objective There are a variety of reasons why there may be an association between asthma and anxiety in children. Research into the relation between asthma and anxiety has been limited by the sole use of parent-reported or self-reported asthma symptoms to define asthma status. The objective of this study was to determine if children with physician-defined asthma are more likely to suffer anxiety than children without asthma.

Design A population-based, cross-sectional assessment, of self-reported anxiety symptoms.

Setting and participants Children aged 5–13 years from Barwon region of Victoria, Australia. Asthma status was determined by review with a paediatrician. Controls were a sample of children without asthma symptoms (matched for age, gender and school).

Outcome measure The Spence Children's Anxiety Scale (SCAS) written questionnaire. The authors compared the mean SCAS score, and the proportion of children with an SCAS score in the clinical range, between the groups.

Results Questionnaires were issued to 205 children with asthma (158 returned, response rate 77%), and 410 controls (319 returned, response rate 78%). The SCAS scores were higher in asthmatics than controls (p<0.001); and were more likely to be in the clinical range (OR=2.5, 95% CI 1.1 to 5.8, p=0.036). There was no evidence that these associations could be explained by known confounding factors.

Conclusions Children with asthma are substantially more likely to suffer anxiety than children without asthma. Future studies are required to determine the sequence of events that leads to this comorbidity, and to test strategies to prevent and treat anxiety among children with asthma.

Cultural feelings and the making of meaning

Cultural feelings are an undertheorised area of the human experience which are recently gaining attention and which need to be understood in the context of museum visitor studies where they are largely ignored. Drawing on a long-term narrative study of global visitors to the Museum of New Zealand Te Papa Tongarewa (Te Papa), this paper unearths the conditions of meaning-making or hermeneutic foundations that facilitate the subsequent processes of meaning-making or interpretations. It argues that the engagement with a museum space starts on a sensory, emotive and embodied level. Visitors’ narrations of their visit to the museum reveal that emotions and feelings are not separate stages of the museum experience but are continuously interwoven with intellectual and interpretive processes. Importantly, the empirical evidence shows that certain meanings remain on an embodied level as an ‘internal understanding’ and resist any verbal ‘expressibility’. The conditions flow into the processes of meaning-making during cross-cultural encounters within the material museum world. Here, feelings enter into the realm of culture and thus into the experience of heritage.

Is a change in mode of travel to school associated with a change in overall physical activity levels in children? Longitudinal results from the SPEEDY study

Background
Children who use active modes of travel (walking or cycling) to school are more physically active than those who use passive (motorised) modes. However, less is known on whether a change in mode of travel to school is associated with a change in children’s physical activity levels. The purpose of this analysis was to investigate the association between change in mode of travel to school and change in overall physical activity levels in children.

Methods
Data from 812 9–10 year old British children (59% girls) who participated in the SPEEDY study were analysed. During the summer terms of 2007 and 2008 participants completed a questionnaire and wore an accelerometer for at least three days. Two-level multiple linear regression models were used to explore the association between change in usual mode of travel to school and change in objectively measured time spent in MVPA.

Results
Compared to children whose reported mode of travel did not change, a change from a passive to an active mode of travel was associated with an increase in daily minutes spent in MVPA (boys: beta 11.59, 95% CI 0.94 to 22.24; girls: beta 11.92, 95% CI 5.00 to 18.84). This increase represented 12% of boys’ and 13% of girls’ total daily time spent in MVPA at follow-up.

Conclusion
This analysis provides further evidence that promoting active travel to school may have a role in contributing to increasing physical activity levels in children.

Discriminant validity of the sensory profile in Australian children with autism spectrum disorder

Objective. The discriminant validity of the Sensory Profile was evaluated by comparing the sensory processing scores of Australian children, 5 to 8 years of age, diagnosed with autism spectrum disorder (ASD) to a control group of children with typical development matched for age and gender. Method. Twenty-six parents of children with ASD and 26 parents of typically developing children without ASD completed the Sensory Profile. Sensory Profile category, factor, and quadrant scores were compared using multivariate analysis to investigate if there were differences between the two groups. Results. The results indicated that the children with ASD had significantly lower sensory processing scores on all fourteen categories, eight out of nine factors, and all four quadrants of the Sensory Profile. Conclusion. The results also provide evidence of discriminant validity of Sensory Profile scores between children with ASD and children with typical development. In addition, the study findings indicate that the Sensory Profile can be used with confidence in cross-cultural contexts, such as Australia.

Physical activity of young children

Occupational therapists concerned with the long-term health and welfare of children need be aware of the decline in physical activity of children in most Western societies. The current study examined the extent of physical activity in the lives of 50 Australian children with mean age of 7.74 years through questionnaires completed by the children’s parents and pedometer (step) data collected from the children during 4 days. The current data show that higher self-perception of physical competence, child’s levels of physical skill, and low parental perception of peer teasing were the best predictors of physical activity. Higher family socioeconomic status was found to be a significant predictor of more steps being taken on weekends, and partner’s (usually a father’s) level of exercise was an important predictor of the number of weekend steps. Children who were perceived to experience more peer teasing completed fewer steps the weekend. The findings from this study indicate that children’s physical activity levels depend on the availability of family resources, and that children in their early school years already experience negative effects from teasing that, combined with reduced self-confidence, may lay the foundation for their withdrawing from physical activity as they get older.

Cultural issues in understanding and treating obsessive compulsive and spectrum disorders

This chapter discusses the cross-cultural understanding of the obsessive compulsive and spectrum disorders. Epidemiological studies suggest a reasonably consistent prevalence of OCD around the world. The role of other culturally influenced factors in the presentation of OCD is also considered (i.e., religiosity, superstition, and beliefs), with religion considered particularly important in the presentation of OCD, although not in its prevalence per se. Treatment effect sizes across countries and within minority cultures from Western countries are outlined. The influence of cultural factors on help-seeking behaviors, assessment, misdiagnosis, and treatment are considered. Limitations of the literature base are discussed, particularly the lack of non-Western studies of treatment effects, and the low evidence base for the spectrum disorders.

Researching the relationship between physical activity and motherhood in older Somali women

This thesis explores participation in physical activity by a group of older Somali women living in Melbourne, Australia. First, it describes the methodological challenges faced by a white researcher conducting cross-cultural research; second, it explores how participants' experiences of motherhood and physical activity in Somalia and Australia influence their participation in physical activity. This research contributes data to address the scarcity of knowledge and research on physical activity amongst older African and Muslim women.
