Investigating self-reported food allergy prevalence in Waterloo Region,Canada

While food allergy prevalence has been studied at the national level, we know little of food allergy prevalence or perceptions of prevalence/management at the local level. This paper uses Waterloo Region as a case study to 1) document self-reported individual and household food allergy and sensitivity prevalence at the local level; 2) investigate perceptions of food allergy prevalence; and 3) explore perceived confidence in anaphylaxis management. Survey data were collected from January to March 2019. Respondents (n = 500) self-reported individual and household food allergy and sensitivity, estimated the percentage of Canadians with food allergy, and were queried about their knowledge of food allergy management. Prevalence estimates were weighted to the structure of the 2016 Canadian Census, and univariate and bivariate analysis were conducted. Prevalence of self-reported food allergy was 12.1% (95%CI, 8.8%-15.3%), and prevalence of self-reported food sensitivity was 26.3% (95%CI, 21.9%-30.7%). When asked to estimate the percentage of Canadians with food allergy, the mean perceived percentage was 35.1% (SD = 22.96). Self-reported prevalence of food allergy appears higher in Waterloo Region, and the estimated percentage of Canadians with food allergy is inflated. Understanding prevalence and perceptions at the local level is important for targeted allocation of public health resources to ensure safe spaces for individuals with food allergy.

A Bayesian approach to rapid seismic vulnerability assessment at urban scale

The seismic vulnerability of city centers is commonly assessed by extending the study methods applied to single buildings to urban aggregations. This approach is not always applicable at territorial scale, as it is uneconomical in terms of time and costs. An innovative method provides reasonable large-scale a priori estimation of parameters not directly evaluable from the exterior of buildings by elaborating values which can be measured from the outside. Those parameters are treated as continuous variables, by assigning them a suitable probability density function. The Bayesian approach is adopted, which allows the update of initial hypotheses by using new data gathered during on-site surveys. In this regard, a rapid survey form for the on-site data collection is proposed. An example of its application to a façade of a building structural unit in Santo Stefano di Sessanio in L’Aquila province (Italy) is proposed, showing promising preliminary results for buildings belonging to Italian historical centers.     

The Irish rent … and mended: transitional textual communities in nineteenth-century America

In this paper, traditional folkloric forms that were ritualised and practised in pre-Famine Ireland are examined. So, too, are the strategies that storytellers employed in disseminating the imaginative aspects of the oral tradition to their audiences. Following the disruption of the storytelling tradition precipitated by the Great Famine and emigration, the fabric of Irish storytelling lay threadbare, both in Ireland and abroad. Of interest is the fact that in America the less “heroic” and more subtle strands of Irish folklore resurfaced in the theatrical venues that developed during the second half of the nineteenth century, namely, minstrelsy, Vaudeville, and Tin Pan Alley. By the turn of twentieth century, the Irish were responding to other “heroic” depictions of themselves, not only with protestation but also with “tongue-in-cheek” laughter. Their grounding in a variety of folkloric texts in Ireland enabled them to transition to multiple kinds of accommodation and expressive resistance.
