title: The PEAR Tool: evaluating portion sizes of food and beverages in food advertising to children using Google Street View

authors: Porter, Jessica

subjects: Children

abstract: Previous research has established where and what types of advertising are in children’s neighbourhoods. However, no prior research has evaluated the portion sizes in advertisements or how these compare with national dietary recommendations. This study aimed to evaluate portion sizes in advertising on bus shelters surrounding schools in Auckland, New Zealand using images captured on Google Street View. Portion sizes for 265 foods or beverages in 172 advertisements on bus shelters within 500 m of Auckland schools were analysed to determine the discrepancy with nutritional guidelines. School type, decile, distance from school boundary, Walk Score® and Transit Score were analysed. Advertised foods and beverages were exaggerated in all but one advertisement. The main findings demonstrate 1) advertised food and beverage products are enlarged, and 2) advertised portion sizes exceed those deemed appropriate in national nutrition guidelines. Stricter advertising policies with revised definitions are needed to improve the food environments surrounding schools.

title: Modelling post-earthquake building recovery under human resource constraints

authors: Li, Lianyan

abstract: Demand surge phenomenon as a result of shortages of human resources needed for post-disaster recovery and reconstruction can be detrimental to recovery outcomes. To quantify the impact of human resource constraints on the recovery of an urban environment, this research introduces a novel Dynamic Stochastic Queuing (DSQ) model, revealing such dynamic interplays over time. Central to this model is the incorporation of a spectrum of socioeconomic factors to formulate optimal recovery strategies under different dynamic resource mobilisation patterns. A recovery efficiency index is defined and employed as a proxy to facilitate comparisons across diverse recovery strategies. A case study is presented to illustrate the application of the model by simulating the building recovery of a portfolio of residential buildings in New Zealand following the 2010–2011 Canterbury Earthquake Sequence (CES). The findings indicate that proactive resource mobilisation strategies can significantly enhance both recovery efficiency and speed. It becomes possible to shorten the post-disaster recovery time significantly by strategically sequencing repairs of damaged structures while taking into account resource mobilisation strategies.

title: Community-university collaborations: creating hybrid research and collective identities

authors: Cave, Jennifer Barbara Jane

subjects: collaborative

abstract: In this article we explore the politics of community-university collaborative research and activism. We are scholars based in universities as well as members of various 'communities'-queer, Pasifika and Māori-hence we regularly venture beyond the formal research spaces of the academy and enter into critical collaborative research with others working in 'the community'. In what follows we first outline collaborative community-based research literature that advocates hybrid research collectivities. Second, we give some context and background to our methodologies that have enabled us to re-think collaborative research. Third, examples from our research are offered to illustrate the ways in which collaborative research constructs new collective identities. Finally, we conclude by arguing that social science scholars working across university-community boundaries may expand and multiply hybrid research collectives, and thereby effect positive social change at many levels
