Reflecting on Hybrid Events: Learning from a Year of Hybrid Experiences

The COVID-19 pandemic led to a sudden shift to virtual work and events, with the last two years enabling an appropriated and rather simulated togetherness - the hybrid mode. As we return to in-person events, it is important to reflect on not only what we learned about technologies and social justice, but about the types of events we desire, and how to re-design them accordingly. This SIG aims to reflect on hybrid events and their execution: scaling them across sectors, communities, and industries; considering trade-offs when choosing technologies; studying best practices and defining measures of "success"for hybrid events; and finally, identifying and charting the wider social, ethical, and legal implications of hybrid formats. This SIG will consolidate these topics by inviting participants to collaboratively reflect on previous hybrid experiences and what can be learned from them

Providing real-time assistance in disaster relief by leveraging crowdsourcing power

Crowdsourcing platforms for disaster management have drawn a lot of attention in recent years due to their efficiency in disaster relief tasks, especially for disaster data collection and analysis. Although the on-site rescue staff can largely benefit from these crowdsourcing data, due to the rapidly evolving situation at the disaster site, they usually encounter various difficulties and have requests, which need to be resolved in a short time. In this paper, aiming at efficiently harnessing crowdsourcing power to provide those on-site rescue staff with real-time remote assistance, we design and develop a crowdsourcing disaster support platform by considering three unique features, viz., selecting and notifying relevant off-site users for individual request according to their expertise; providing collaborative working functionalities to off-site users; improving answer credibility via “crowd voting.” To evaluate the platform, we conducted a series of experiments with three-round user trials and also a System Usability Scale survey after each trial. The results show that the platform can effectively support on-site rescue staff by leveraging crowdsourcing power and achieve good usability

Equivalência transcultural de três escalas utilizadas para estimar a aptidão cardiorrespiratória: estudo em idosos Cross-cultural equivalence of three scales used to estimate cardiorespiratory fitness in the elderly

O objetivo deste estudo foi realizar a equivalência transcultural de escalas empregadas para a avaliação do nível de atividade física e que são utilizadas como estimativas da aptidão cardiorrespiratória, para posterior utilização em indivíduos idosos. Três escalas foram determinadas após revisão sistemática: Veterans Physical Activity Questionnaire (VSAQ), Rating of Perceived Capacity (RPC) e Physical Activity Rating (PA-R). Para a análise da equivalência, utilizou-se o modelo proposto por Herdman et al. Como parte do processo, a confiabilidade teste-reteste foi avaliada em uma amostra composta por 12 idosos com idade de 74,5 ± 3,5 anos, pelo cálculo dos coeficientes de concordância de Lin (CCL) e de correlação intraclasse (CCI). Detectou-se uma boa reprodutibilidade das escalas com exceção do RPC. Apesar de a quantidade de indivíduos não permitir conclusões mais aprofundadas, os resultados podem indicar necessidade de mudanças na estrutura de algumas escalas originais. Por fim, acredita-se que os resultados obtidos no presente estudo sugerem a adequação das versões das escalas para a língua portuguesa, havendo, todavia, a necessidade de um estudo de validade de critério das escalas.<br>This study aimed at establishing the cross-cultural equivalence of scales used to evaluate physical activity level and measure cardiorespiratory fitness, for further application in elderly subjects. Three scales were identified after systematic review: Veterans Physical Activity Questionnaire (VSAQ), Rating of Perceived Capacity (RPC), and Physical Activity Rating (PA-R). The model proposed by Herdman et al. was applied to analyze equivalence. Test-retest reliability was calculated in a sample of 12 elderly subjects (74.5 ± 3.5 years) using Lin's concordance coefficient and intraclass correlation coefficient. Good reproducibility was detected in all scales except RPC. Due to the small sample size, hardly any conclusions can de drawn, but the results point to the need for changes in the original scale's structures. The findings also suggest the adequacy of the scale's Portuguese-language version, although further validity studies appear to be necessary
