During the spread of COVID-19, many laboratories used the “Formulation 1” proposed by the World Health Organization to prepare hand sanitizers. Taking into consideration its ingredients and the prolonged use of hand sanitizers, “Formulation 1” (P1) was compared with two gel formulations (P2 and P3) prepared with the addition of natural emollients and two different viscosity enhancers to define their chemical–physical stability, biocidal efficacy, and in vivo acceptability and tolerability. P1 resulted in the most efficient biocide but was poorly tolerated by the skin and not acceptable in volunteer hedonic evaluation, especially in terms of irritation and drying effect, with an expectable reduction in the compliance. Moreover, its liquid formulation is unpractical and can cause ethanol evaporation. P2 and P3 proved to be both good products regarding pH and alcohol strength values. However, in terms of viscosity, texture, ease of use, and application, P3 seemed to be a better gel product than P2. Moreover, they were well tolerated by the skin, increasing the hydration of the stratum corneum, due to the addition of Calendula officinalis and Aloe vera. Despite a lower ethanol concentration than P1, P2 and P3 also showed a good biocide efficiency, with better results in P2. In conclusion, these gel formulations proved to be more convenient for long-term use with a good balance between efficacy, safety, and compatibility with the skin.

As the climate crisis is turning into one of the most critical issues of our time, HCI researchers keep reflecting on the role their work can play in reducing the impact of adverse environmental changes. Suggestions have been made to expand Sustainable HCI (SHCI)’s intervention area to policy design to have a larger impact, consider non-human actors’ perspective to incorporate the value of biodiversity, develop multidisciplinary competencies and work across disciplines to understand climate change, and finally make it understandable to citizens and pave the way for their action. This workshop calls to discuss the different angles from which the problem of climate change has been addressed by the CHI community so far. We believe these different angles have several contact points, and the convergence of these different perspectives would help HCI researchers better imagine sustainable futures.

Child independent mobility (CIM) refers to the freedom and capability of children to move about their local neighborhoods without constant direct adult supervision. Our climb project combats an observed decline in CIM, offering a pervasive gameful platform for home–school mobility composed of three primary components: the first two using technology to support different levels of child independence and the third providing an element of continuous motivation for positive behavior change. This paper describes these three novel technologies: PedibusSmart, SafePath, and KidsGoGreen, and reports on four years of success with more than 1800 elementary age children, their teachers, and families. We further show how (i), disappearing, pervasive technology contributes to successful adoption, (ii), properly balancing trust and tracking leads to useful, noninvasive technological support, and (iii), in-classroom, gameful technology engages and motivates participation, with behavior changes persisting over time.

This paper investigates the challenges of designing a computer supported collaborative environment aimed at facilitating co-production processes, i.e., those collaborative processes between Public Administrations, private stakeholders and citizens that aim at the design of public services, their implementation, and their shared delivery to the community. We argue that, for such a digital platform, different types of socio-technical requirements should be considered, i.e., those related to governance models and associated collaboration dynamics; requirements that may emerge from the specific type of public service to design; as well as user and technical requirements common to all e-government platforms. This research informed the development and testing of a digital collaboration platform that offers guidance on how to organize a co-production initiative and a network of stakeholders, functionalities to support collaborative work, and enablers (in the form of reusable knowledge and digital resources) to perform the sequence of steps to produce a public service. The lessons learned from the iterative platform development process and a preliminary evaluation study conducted with three Public Administrations in different European countries pointed at specific functionalities that are perceived as most crucial and at different appropriation practices that depend on the organizational structure of the involved Public Administrations and related multi-stakeholder networks. The innovation that is brought about with respect to general-purpose platforms for computer supported cooperative work is represented by the operationalization of co-production processes, with step-by-step guidance and potential reuse (with adaptation) of ready to use resources and processes. Based on the results of our research, general guidelines are also proposed for the design of future digital platforms supporting co-production.
