Exploring mathematics and computational thinking with (Un)plugged activities with children from 6 to 9 years old

This article presents an exploratory research, with a qualitative approach, on the use of (un)plugged activities to teach computing and mathematic concepts during the social isolation period imposed by the Covid-19 pandemic. The objective of this research was to analyze the use of such activities as extra resources in the context of remote education to teach computational thinking and mathematics skills to 6-to-9-year-old children. The results showed children's great engagement in the activities, and the acceptance of unplugged activities by both the children and their families. © 2023, Centro de Estudos Educacao e Sociedade - CEDES.

Dead Users' Profiles on Facebook: Limited Interaction Beyond Human Existence

Death has become increasingly visible on social networks, especially after COVID-19, and Facebook addresses that with double standards: while some profiles remain active, others turn into memorials. This article investigates how Facebook's system deals with dead users' profiles either to support or restrict interactions concerning users' deaths. Our qualitative analysis of data from 54 public profiles of people who died between June 2020 and March 2021 showed that (i) Facebook fails to communicate the criteria for transforming profiles into memorials;(ii) no information about their contacts of deceased users' profiles is given;(iii) the frequency of interaction with memorials and with active profiles is different;(iv) profiles' privacy settings shape interaction. Our results exemplify how a sociotechnical system influences people's interactions with dead users' profiles. We herein highlight implications for interaction design and evaluation, besides the need to consider interaction as existence, which raises big challenges to the Human Computer Interaction (HCI) community.

O Impacto Da Pandemia Covid-19 Na Manutencao Do Estoque De Sangue Em Um Hemocentro No Ceara

Introducao: A doacao de sangue e um ato voluntario e altruista, necessaria para a manutencao de estoque minimo de seguranca de hemocomponentes destinados ao suporte de pacientes clinicos e cirurgicos. Durante o auge da pandemia do COVID-19, as doacoes de sangue e hemocomponentes diminuiram consideravelmente em todo o Brasil. Nesse cenario, foi necessario utilizar o plano nacional de contingencia, pois alguns estados nao conseguiram manter o estoque minimo, como preconizado pelo Ministerio da Saude (MS), definido como o numero de Concentrados de Hemacias (CH) necessarios para manter o atendimento transfusional por 3 dias. Uma plataforma do MS, chamada Hemovida, e utilizada para o gerenciamento do estoque na hemorrede nacional. A partir das informacoes de estoque enviadas diariamente por todos os hemocentros, e possivel realizar a transferencia de hemocomponentes em situacoes de emergencia. Objetivos: O objetivo deste trabalho e descrever como o Centro de Hematologia e Hemoterapia do Ceara - HEMOCE manteve seu estoque seguro e como contribuiu no remanejamento de hemocomponentes dentro do Brasil no auge da pandemia da COVID-19. Material e metodo Trata-se do relato das acoes do HEMOCE nos anos de 2020 e 2021. Resultados: Com algumas estrategias criadas pelo hemocentro coordenador, o estado do Ceara nao sofreu um grande impacto, apesar de ter sido um dos primeiros estados a decretar lockdown, visto a utilizacao do gerenciamento de estoque na hemorrede estadual. Como a capital foi a primeira cidade atingida pela pandemia, os hemocentros regionais, como Crato, Quixada, Iguatu e Sobral, conseguiram manter um bom numero de doacoes e suprir toda a necessidade do estado. Quando o pico da pandemia chegou no interior do estado o hemocentro coordenador ja havia preparado VARIAS estrategias: a) Promocao da seguranca ao doador, com coletas por agendamento;disponibilizacao de alcool e mascaras, demarcacao de cadeiras para adequado distanciamento;b) Promocao da captacao: uso do aplicativo Whatsapp, intensificacao de ligacoes telefonicas, criacao do portal do doador, estabelecimento de novas parcerias para coletas externas;c) Otimizacao da producao e da distribuicao de hemocomponentes: coleta por aferese no interior do estado;centralizacao da producao em tres hemocentros;redistribuicao de hemocomponentes na hemorrede, intensificacao das acoes de gerenciamento de sangue do paciente e uso racional de hemocomponentes, controle da liberacao de concentrado de plaquetas, com avaliacao obrigatoria de hemoterapeuta;intensificacao dos contatos com medicos prescritores. Essas acoes permitiram manter o estoque de no minimo de 6 dias. Discussao e conclusoes Dessa forma, o HEMOCE conseguiu remanejar CH para outros estados, que se encontravam em situacao de emergencia, como Parana, Sao Paulo e Minas Gerais, com o apoio do MS. Ao total, foram 3225 CH remanejados por todo o pais, sendo 1118 (35%) provenientes do HEMOCE. Copyright © 2022

Perspectives on interaction with dead users' profiles on Facebook

With the Covid-19 pandemic, death has become an increasingly present and visible phenomenon on social networks. On Facebook, there is not a homogeneous treatment of death among deceased users' profiles: some remain active, whereas others are turned into memorials, but the criteria for this transformation are not clear. In both cases, privacy settings limit the interaction. These different possibilities give rise to different interactions and reactions among users. This paper addresses how dead users' profiles, multiplied due to the current pandemic, have been treated by Facebook's social-technical system, in comparison to possible posthumous interactions in the physical world. Our main objective is to understand to what extent Facebook's technical system supports or restricts social interactions concerning users' deaths. We carried out a qualitative exploratory analysis of data from 54 Facebook profiles belonging to people who passed away between June 2020 and March 2021. Among other results, we noticed: that Facebook fails to publicize the criteria for transforming active profiles into memorials and who are their heir contacts;that there is a difference in the amount and frequency of interactions between profiles transformed into memorials and those that remain active;and that profiles' privacy settings interfere with social interaction. This situation directly influences the ways other users relate or not with such profiles, which is an object of paramount importance in Human-Computer Interaction studies, especially when considering interaction as existence. © 2021 ACM.
