The limits of HCD:reimagining the anthropocentricity of ISO 9241-210

Human-centred design (HCD) is just that: human-centred. As we approach the limits of Earth's biophysical systems, it no longer feels appropriate to place humans at the centre of design decisions. Yet HCD and its ISO—ISO-9241-210:2010—continue to be powerful and popular tools within many computing and design departments, as well as in their affiliated industries. These design approaches are perpetuating the trend of incremental improvements to the living standards of the already privileged and digitally connected whilst ignoring the broader environmental and socio-political effects of digital technologies. In this paper, we attempt to reimagine HCD and its ISO by drawing on fields and concepts such as sustainable interaction design (SID), animal-computer interaction (ACI), and object oriented ontology (OOO). Through this, we contribute a preliminary set of proposals about what needs to change with HCD and its ISO. We close by discussing the ISO development process and suggesting routes for environmentally concerned researchers to influence the evolution of HCD's ISO

Cost-Effectiveness of Rotavirus Vaccination in France-Accounting for Indirect Protection.

BACKGROUND: Vaccination against rotavirus has shown great potential for reducing the primary cause of severe childhood gastroenteritis. Previous economic evaluations of rotavirus vaccination in France have not modeled the potential impact of vaccines on disease burden via reduced transmission. OBJECTIVE: To determine the cost-effectiveness of the introduction of pentavalent rotavirus vaccination into the French infant vaccination schedule. METHODS: We developed an age-structured model of rotavirus transmission calibrated to 6 years of French gastroenteritis incidence and vaccine clinical trial data. We evaluated the cost-effectiveness of pentavalent rotavirus vaccination considering that 75% of infants would receive the three-dose vaccine course. RESULTS: Our model predicts that rotavirus vaccination will decrease rotavirus gastroenteritis incidence and associated clinical outcomes in vaccinated and unvaccinated individuals, delay the seasonal peak of infection, and increase the age of infection. From the societal perspective, our base-case scenario predicts that vaccination coverage would be cost-effective at €115 or €135 per vaccine course at €28,500 and €39,500/quality-adjusted life-year (QALY) gained, respectively, and suggests that almost 95% of the financial benefits will be recouped within the first 5 years following vaccination implementation. From the third-party payer perspective, incremental cost-effectiveness ratios ranged from €12,500 to €20,000/QALY, respectively. Our uncertainty analysis suggests that findings were sensitive to various assumptions including the number of hospitalizations, outpatient visits, and the extent of QALY losses per rotavirus episode. CONCLUSIONS: Introducing pentavalent rotavirus vaccination into the French infant vaccination schedule would significantly reduce the burden of rotavirus disease in children, and could be cost-effective under plausible conditions

The Limits of Evaluating Sustainability

Designing technology with sustainability in mind is becoming more and more important, especially considering future scenarios of limited resources where the world’s current lifestyle of wasteful consumption needs to change. But how can researchers believably argue that their solutions are indeed sustainable? How can consumers and technology users reliably acquire, understand, and apply information about environmental sustainability? Those questions are difficult to answer, especially in research domains where the impact on sustainability is not immediately measurable, such as sustainable HCI. The evaluation of sustainability is an ongoing problem that is often glossed over, but we believe the community needs to intensify its efforts to articulate its evaluation methods to other disciplines and external stakeholders. Even if those disciplines and stakeholders understand the importance of designing for sustainability, we need convincing arguments – such as validation through thorough evaluations – to showcase why a specific design solution works in the real world. In this paper, we analyze this problem by highlighting examples of sustainable HCI research in which evaluation of sustainability failed. We also look at previous research that sought to address this issue and discuss how their solutions can be generalized – and when they might fail. While we do not have the final answer, our intention is to start a discussion as to why sustainable HCI research is oftentimes not doing enough to justify the validity of its solutions. We close our paper by suggesting a few examples of what we believe to be potential ways to address those issues and take action to improve the evaluation of sustainability

Marginalized Youths Constructing Identities: A Literature Review of STEM Discourses

Colonialism gave rise to cultures of power, positioning non-white traditions and cultures as “inferior,” including knowledge and education practices (Rosa & Mensah, 2021). As such, many children identifying with marginalized ethnic, racial, and/or gender groups, encounter sometimes contradictory and often deconstructive messaging from their educational and social orbits about their personal alignment with STEM (Cian et al., 2022). Consequently, minoritized learners are often faced with a requirement that, in order to persevere, they must adopt characteristics that the cultures of power in STEM embrace, such as girls pursuing physics disassociating themselves from femininity and highlighting masculinity in the way they present themselves (Francis et al., 2016). Furthermore, youths of color find themselves using survival strategies, such as “acting white” (McGee, 2016), in order to join STEM communities, which may result in dissonance with one’s cultural identities. In this literature review, I will unpack empirical research that illustrates how the STEM identity of youths is influenced by interactions with significant persons in the home and the school. The aim of this literature review is to inform future research in STEM identity development of youth who identify with communities marginalized in STEM spaces

Cost-effectiveness of vaccination with a quadrivalent HPV vaccine in Germany using a dynamic transmission model

Introduction Persistent infections with human papillomavirus (HPV) are a necessary cause of cervical cancer and are responsible for important morbidity in men and women. Since 2007, HPV vaccination has been recommended and funded for all girls aged 12 to 17 in Germany. A previously published cost-effectiveness analysis, using a static model, showed that a quadrivalent HPV vaccination programme for 12-year-old girls in Germany would be cost effective. Here we present the results from a dynamic transmission model that can be used to evaluate the impact and cost-effectiveness of different vaccination schemas. Methods We adapted a HPV dynamic transmission model, which has been used in other countries, to the German context. The model was used to compare a cervical cancer screening only strategy with a strategy of combining vaccination of females aged 12–17 years old and cervical cancer screening, based on the current recommendations in Germany. In addition, the impact of increasing vaccination coverage in this cohort of females aged 12–17 years old was evaluated in sensitivity analysis. Results The results from this analysis show that the current quadrivalent HPV vaccination programme of females ages 12 to 17 in Germany is cost-effective with an ICER of 5,525€/QALY (quality adjusted life year). The incremental cost-effectiveness ratio (ICER) increased to 10,293€/QALY when the vaccine effects on HPV6/11 diseases were excluded. At steady state, the model predicted that vaccinating girls aged 12 to 17 could reduce the number of HPV 6/11/16/18-related cervical cancers by 65% and genital warts among women and men by 70% and 48%, respectively. The impact on HPV-related disease incidence and costs avoided would occur relatively soon after initiating the vaccine programme, with much of the early impact being due to the prevention of HPV6/11-related genital warts. Conclusions These results show that the current quadrivalent HPV vaccination and cervical cancer screening programmes in Germany will substantially reduce the incidence of cervical cancer, cervical intraepithelial neoplasia (CIN) and genital warts. The evaluated vaccination strategies were all found to be cost-effective. Future analyses should include more HPV-related diseases

Landslide Detection in Real-Time Social Media Image Streams

Lack of global data inventories obstructs scientific modeling of and response to landslide hazards which are oftentimes deadly and costly. To remedy this limitation, new approaches suggest solutions based on citizen science that requires active participation. However, as a non-traditional data source, social media has been increasingly used in many disaster response and management studies in recent years. Inspired by this trend, we propose to capitalize on social media data to mine landslide-related information automatically with the help of artificial intelligence (AI) techniques. Specifically, we develop a state-of-the-art computer vision model to detect landslides in social media image streams in real time. To that end, we create a large landslide image dataset labeled by experts and conduct extensive model training experiments. The experimental results indicate that the proposed model can be deployed in an online fashion to support global landslide susceptibility maps and emergency response

“Sustainability... it’s just not important.”:The Challenges of Academic Engagement with Diverse Stakeholders

Research at the intersection of sustainability and computing often engages with external stakeholders, and those engagements can determine success and impact of the sustainable goals as well as the entire research. In this paper, we reflect on various stakeholder en- gagements to derive lessons for the ICT4S community that seeks to broaden its sustainable impact beyond their own field. We briefly describe our experiences with case studies from each of the individual author’s research, and then synthesize across those experiences to reflect on similarities and differences. The resulting discussion highlights what we feel were our important lessons learned, as well as some of our thoughts on how to approach collab- orations or deployments with external stakeholders in sustainable computing projects
