In this work, we examine a novel forecasting approach for COVID-19 case prediction that uses Graph Neural Networks and mobility data. contrast to existing time series models, the proposed learns from single large-scale spatio-temporal graph, where nodes represent region-level human mobility, spatial edges based inter-region connectivity, temporal node features through time. We evaluate on US county level dataset, demonstrate rich information leveraged by graph neural network allows model...

Graph neural networks (GNNs) have emerged as a powerful approach for solving many network mining tasks. However, learning on large graphs remains challenge -- recently proposed scalable GNN approaches rely an expensive message-passing procedure to propagate information through the graph. We present PPRGo model which utilizes efficient approximation of diffusion in GNNs resulting significant speed gains while maintaining state-of-the-art prediction performance. In addition being faster, is...

In order compare on dimensions, MANCOVAs computed using age, duration,...

This qualitative study documents incidents of discrimination and violence among LGBTQ + youth experiencing homelessness along with their adaptation strategies. Using intersectionality theory, this analysis is based on individual interviews conducted 17 aged to 25. According stories, experienced various types in the context homelessness. Youth report anticipating physical psychological from passersby public spaces, causing them hide gaze others. They also that police profiling racialized...

To reflect the complex phenomena of child sexual abuse (CSA), studies should examine possible gender specificities and explore potentially explanatory mechanisms. The current study aimed to test moderating effect in mediated relationship between CSA, self-esteem, delinquency during adolescence. A moderated mediation model was tested among a representative sample 8,194 high school students (57.8% girls 42.2% boys) age 14 18 province Quebec Canada. Results showed that self-esteem has an...
