Isolation contributes to deteriorating health outcomes during the first 1000 days of a child's life (the period from conception to two years). Mothers and their growing babies are at risk of pregnancy-related complications and malnutrition during this sensitive period due to inadequate information. This study describes how a faith-based organization (FBO) in Cape Town leverages available resources in both physical and virtual spaces to support mothers through antenatal classes. We observed seven small groups in their physical spaces, interviewed seven mothers and analyzed fifteen WhatsApp chat groups to understand the group structure, dynamics, and interactions. When the model was introduced to the mothers in the physical and virtual spaces simultaneously, cohesion was achieved and sustained. However, during the COVID-19 pandemic, where strong indications of stress and isolation were evident, a strange paradox was noted: all groups showed weak ties (with minimal communication among members). It was hard to explain the non-commitment despite efforts from the moderators to encourage sharing among mothers. We identified two underlying causes: a minimal sense of belonging to the group and bandwidth constraints. Further analysis showed that bandwidth constraints digitally excluded some mothers from active participation. These findings indicated the need for HCI and technology designers to design less bandwidth-intensive interactive platforms for inclusivity.
在儿童生命的头1000天(从受孕到两岁),孤立会导致健康状况恶化。在这一敏感时期,由于信息不足,母亲及其成长中的婴儿面临与妊娠有关的并发症和营养不良的风险。本研究描述了开普敦的一个基于信仰的组织(FBO)如何利用物理和虚拟空间的可用资源,通过产前课程为母亲提供支持。我们在他们的物理空间中观察了7个小组,采访了7位母亲,分析了15个WhatsApp聊天群,以了解群体结构、动态和互动。当模型同时在物理空间和虚拟空间中引入母亲时,实现了凝聚力并保持了凝聚力。然而,在2019冠状病毒病大流行期间,有明显的压力和孤立迹象,人们注意到一个奇怪的悖论:所有群体都表现出弱联系(成员之间的沟通很少)。尽管主持人努力鼓励母亲们分享,但很难解释这种不投入的现象。我们确定了两个潜在的原因:对群体的归属感和带宽限制。进一步的分析表明,数字带宽限制使一些母亲无法积极参与。这些发现表明,HCI和技术设计师需要设计更少带宽密集型的交互平台,以实现包容性。

Algorithmic Waste Reduction 算法减少废物
Pub Date : 2022-06-29 DOI: 10.1145/3530190.3534815
J. C. Aguma, Michael Demirev
Motivated by a desire for waste reduction through surplus redistribution, we explore the paradox of overproduction of resources that are wasted at several levels of the supply chain and the concurrent lack of access to, in most cases, overproduced basic resources by low income socioeconomic classes to whom resource access is normally only available through donation centers. To that end, we contrast two surplus redistribution solutions to this paradox. (1) Local independent donations between producers and donation centers. (2) Redistribution by way of a global redistributor (what we will call a core redistributor) who collects donations from all available producers and redistributes the surplus to all donation centers respective of their demanded quantities. We mathematically show that an optimal allocation of the surplus that minimizes waste and maximizes social welfare is only possible with a core redistributor. As this is a deeply social and economic problem rather than mathematical, we also qualitatively study two cases; (1) food waste and food insecurity in the UK, and (2) Los Angeles County’s project RoomKey: a pandemic effort to house covid-vulnerable unhoused persons in vacant hotels and motels. Both case studies give more support for a core redistribution as a solution to waste from overproduction and lack of access to essential resources.
在通过剩余再分配减少浪费的愿望的激励下,我们探讨了在供应链的几个层面上浪费的资源生产过剩的悖论,以及在大多数情况下,低收入社会经济阶层无法同时获得生产过剩的基本资源,他们通常只能通过捐赠中心获得资源。为此,我们对比了这一悖论的两种盈余再分配解决方案。(1)生产者与捐赠中心之间的地方自主捐赠。(2)通过全球再分配者(我们称之为核心再分配者)的方式进行再分配,该再分配者从所有可用的生产者那里收集捐赠,并根据其需求数量将剩余部分重新分配给所有捐赠中心。我们在数学上表明,只有在核心再分配者的情况下,才能实现使浪费最小化和社会福利最大化的剩余最优分配。由于这是一个深刻的社会和经济问题,而不是数学问题,我们也定性地研究了两个案例;(1)英国的食物浪费和粮食不安全;(2)洛杉矶县的RoomKey项目:一项为空置的酒店和汽车旅馆安置易受疫情影响的无家可归者的大流行努力。这两个案例研究都更加支持核心再分配,作为解决生产过剩和无法获得基本资源造成的浪费的办法。

During disasters, emergency shelters play a central role in emergency management, providing both a secure environment and centralized sites for the distribution of information, material relief supplies, and access to health and human services. Despite their importance, challenges such as physical access, public awareness, and peoples’ willingness to relocate limit the impact of both shelters managed by emergency responders and informal locations created by affected communities. This paper presents research conducted as part of a long-term project aimed at designing digital tools to assist communities and formal responders plan and manage emergency shelters. Working with partners in Puerto Rico, we developed and distributed cultural probes in three communities with recent experience of hurricanes and earthquakes to better understand the needs and resources of disaster affected people related to shelter. This approach yielded novel insights that challenge and expand traditional views of emergency shelters and identified several areas where HCI research and design can contribute to the sector.
在灾害期间,应急避难所在应急管理中发挥核心作用,既提供安全的环境,又提供集中的地点,以便分发信息、物资救济用品以及获得保健和人力服务。尽管它们很重要,但诸如实际进入、公众意识和人们重新安置意愿等挑战限制了应急人员管理的庇护所和受影响社区创建的非正式地点的影响。本文介绍了作为一个长期项目的一部分进行的研究,该项目旨在设计数字工具,以帮助社区和正式响应者规划和管理紧急避难所。我们与波多黎各的合作伙伴合作,在最近经历过飓风和地震的三个社区开发并分发了文化探测器,以更好地了解受灾人民在住房方面的需求和资源。这种方法产生了新的见解,挑战和扩展了对紧急避难所的传统看法,并确定了HCI研究和设计可以为该部门做出贡献的几个领域。

Research articles published in medical journals often present findings from causal experiments. In this paper, we use this intuition to build a model that leverages causal relations expressed in text to unearth factors related to Sjögren’s syndrome. Sjögren’s syndrome is an auto-immune disease affecting up to 3.1 million Americans. The uncommon nature of the disease, coupled with common symptoms with other autoimmune conditions make the timely diagnosis of this disease very hard. A centralized information system with easy access to common and uncommon factors related to Sjögren’s syndrome may alleviate the problem. We use automatically extracted causal relationships from text related to Sjögren’s syndrome collected from the medical literature to identify a set of factors, such as “signs and symptoms” and “associated conditions”, related to this disease. We show that our approach is capable of retrieving such factors with a high precision and recall values. Comparative experiments show that this approach leads to 25% improvement in retrieval F1-score compared to several state-of-the-art biomedical models, including BioBERT and Gram-CNN.
发表在医学杂志上的研究文章通常是因果实验的结果。在本文中,我们利用这种直觉建立了一个模型,利用文本表达的因果关系来挖掘Sjögren综合征的相关因素。Sjögren综合征是一种自身免疫性疾病,影响着多达310万美国人。这种疾病的罕见性质,加上与其他自身免疫性疾病的常见症状,使得这种疾病的及时诊断非常困难。一个集中的信息系统,可以方便地获取与Sjögren综合征相关的常见和不常见因素,可能会缓解这个问题。我们使用从医学文献中收集的与Sjögren综合征相关的文本中自动提取的因果关系来识别与该疾病相关的一组因素,如“体征和症状”和“相关条件”。我们表明,我们的方法能够以较高的精度和召回值检索这些因素。对比实验表明,与几种最先进的生物医学模型(包括BioBERT和Gram-CNN)相比,该方法的检索f1分数提高了25%。

Human-wildlife conflict (HWC) is one of the most pressing conservation issues at present, with incidents leading to human injury and death, crop and property damage, and livestock predation. Since acquiring real-time data and performing manual analysis on those incidents are costly, we propose to leverage machine learning techniques to build an automated pipeline to construct an HWC knowledge base from historical news articles. Our unsupervised and active learning methods are not only able to recognize the major causes of HWC such as construction, pollution, and farming, but can also classify an unseen news article into its major cause with 90% accuracy. Moreover, our interactive visualizations of the knowledge base illustrate the spatial and temporal trend of human-wildlife conflicts across India for index by cities and animals. Based on our findings that most conflict zones include areas where human settlements are near forested areas, we extend our study to include satellite imagery to identify such proximity zones. We conduct a case study to use this method to identify human-elephant conflict hotspots in northern and western parts of the Indian state of West Bengal. We expect that our findings can inform the public of HWC hotspots and help in much more informed policymaking.
人类与野生动物冲突(HWC)是目前最紧迫的保护问题之一,其事件导致人类伤亡,作物和财产损失以及牲畜被捕食。由于获取实时数据并对这些事件进行人工分析的成本很高,我们建议利用机器学习技术构建自动化管道,从历史新闻文章中构建HWC知识库。我们的无监督和主动学习方法不仅能够识别HWC的主要原因,如建筑,污染和农业,而且可以将未见的新闻文章分类为其主要原因,准确率为90%。此外,我们的交互式可视化知识库以城市和动物为索引,展示了印度各地人类与野生动物冲突的时空趋势。根据我们的发现,大多数冲突地区包括人类住区靠近森林地区的地区,我们扩展了我们的研究,包括卫星图像,以确定这些接近区域。我们进行了一个案例研究,使用这种方法来确定印度西孟加拉邦北部和西部地区的人象冲突热点。我们希望我们的研究结果可以让公众了解HWC热点,并有助于更明智地制定政策。

The use of blockchain in regulatory ecosystems is a promising approach to address challenges of compliance among mutually untrusted entities. In this work, we consider applications of blockchain technologies in telecom regulations. In particular, we address growing concerns around Unsolicited Commercial Communication (UCC aka. spam) sent through text messages (SMS) and phone calls in India. Despite several regulatory measures taken to curb the menace of spam it continues to be a nuisance to subscribers while posing challenges to telecom operators and regulators alike. In this paper, we present a consortium blockchain based architecture to address the problem of UCC in India. Our solution improves subscriber experiences, improves the efficiency of regulatory processes while also positively impacting all stakeholders in the telecom ecosystem. Unlike previous approaches to the problem of UCC, which are all ex-post, our approach to adherence to the regulations is ex-ante. The proposal described in this paper is a primary contributor to the revision of regulations concerning UCC and spam by the Telecom Regulatory Authority of India (TRAI). The new regulations published in July 2018 were first of a kind in the world and amended the 2010 Telecom Commercial Communication Customer Preference Regulation (TCCCPR), through mandating the use of a blockchain/distributed ledgers in addressing the UCC problem. In this paper, we provide a holistic account of of the projects’ evolution from (1) its design and strategy, to (2) regulatory and policy action, (3) country wide implementation and deployment, and (4) evaluation and impact of the work. While the scope of the work presented in this paper is in the context of the UCC problem in India, we believe that the approach can be generalized to adopt blockchain based solutions to improve regulatory processes in other contexts and countries. We hope this account will serve as a useful case study for the stakeholders of the telecommunications ecosystem and regulators, and motivate countries across the world facing similar challenges to consider the viability of the technology, be convinced to establish it, continue efforts at addressing active research challenges, and scale the technology from our experiences.
在监管生态系统中使用区块链是一种很有前途的方法,可以解决相互不信任实体之间的合规性挑战。在这项工作中,我们考虑了区块链技术在电信法规中的应用。特别是,我们解决了对未经请求的商业通信(UCC)日益增长的担忧。在印度,通过短信和电话发送的垃圾邮件。尽管采取了一些监管措施来遏制垃圾邮件的威胁,但它仍然是用户的滋扰,同时也给电信运营商和监管机构带来了挑战。在本文中,我们提出了一个基于联盟区块链的架构来解决印度的UCC问题。我们的解决方案改善了用户体验,提高了监管流程的效率,同时也对电信生态系统中的所有利益相关者产生了积极影响。与以往处理UCC问题的方法都是事后处理不同,我们遵守规定的方法是事前处理。本文中描述的提案是印度电信监管局(TRAI)修订有关UCC和垃圾邮件的法规的主要贡献者。2018年7月发布的新法规是世界上第一个此类法规,并修订了2010年电信商业通信客户偏好法规(TCCCPR),通过强制要求使用区块链/分布式账本来解决UCC问题。在本文中,我们全面介绍了这些项目的演变过程,从(1)其设计和战略,到(2)监管和政策行动,(3)全国范围内的实施和部署,以及(4)工作的评估和影响。虽然本文所介绍的工作范围是在印度UCC问题的背景下进行的,但我们认为,该方法可以推广到采用基于区块链的解决方案,以改善其他背景和国家的监管流程。我们希望这篇文章能够为电信生态系统的利益相关者和监管机构提供有用的案例研究,并激励世界上面临类似挑战的国家考虑该技术的可行性,被说服建立它,继续努力解决积极的研究挑战,并从我们的经验中扩展技术。

Accelerated Design and Deployment of Low-Carbon Concrete for Data Centers 数据中心低碳混凝土的加速设计和部署

Concrete is the most widely used engineered material in the world with more than 10 billion tons produced annually. Unfortunately, with that scale comes a significant burden in terms of energy, water, and release of greenhouse gases and other pollutants; indeed 8% of worldwide carbon emissions are attributed to the production of cement, a key ingredient in concrete. As such, there is interest in creating concrete formulas that minimize this environmental burden, while satisfying engineering performance requirements including compressive strength. Specifically for computing, concrete is a major ingredient in the construction of data centers. In this work, we use conditional variational autoencoders (CVAEs), a type of semi-supervised generative artificial intelligence (AI) model, to discover concrete formulas with desired properties. Our model is trained just using a small open dataset from the UCI Machine Learning Repository joined with environmental impact data from standard lifecycle analysis. Computational predictions demonstrate CVAEs can design concrete formulas with much lower carbon requirements than existing formulations while meeting design requirements. Next we report laboratory-based compressive strength experiments for five AI-generated formulations, which demonstrate that the formulations exceed design requirements. The resulting formulations were then used by Ozinga Ready Mix—a concrete supplier—to generate field-ready concrete formulations, based on local conditions and their expertise in concrete design.

混凝土是世界上使用最广泛的工程材料,年产量超过100亿吨。不幸的是,这种规模带来了能源、水、温室气体和其他污染物排放方面的沉重负担;事实上,全球8%的碳排放来自水泥的生产,水泥是混凝土的关键成分。因此,在满足包括抗压强度在内的工程性能要求的同时,人们有兴趣创建混凝土公式,以最大限度地减少这种环境负担。特别是对于计算,混凝土是构建数据中心的主要成分。在这项工作中,我们使用条件变分自编码器(CVAEs),一种半监督生成式人工智能(AI)模型,来发现具有所需属性的具体公式。我们的模型仅使用来自UCI机器学习存储库的小型开放数据集以及来自标准生命周期分析的环境影响数据进行训练。计算预测表明,CVAEs可以设计出比现有配方碳要求低得多的混凝土配方,同时满足设计要求。接下来,我们报告了五种人工智能生成配方的实验室抗压强度实验,结果表明配方超出了设计要求。随后,混凝土供应商Ozinga Ready mix根据当地条件和他们在混凝土设计方面的专业知识,使用所得配方生成现场可用的混凝土配方。最后,我们报告了这些公式是如何在美国伊利诺伊州DeKalb的元数据中心的建筑物和结构的建设中使用的。作为实际部署的一部分,现场实验的结果证实了人工智能生成的低碳混凝土混合物的有效性。

Unfortunately, with that scale comes a significant burden in terms of energy, water, and release of greenhouse gases and other pollutants; indeed 8% of worldwide carbon emissions are attributed to the production of cement, a key ingredient in concrete. As such, there is interest in creating concrete formulas that minimize this environmental burden, while satisfying engineering performance requirements including compressive strength. Specifically for computing, concrete is a major ingredient in the construction of data centers. In this work, we use conditional variational autoencoders (CVAEs), a type of semi-supervised generative artificial intelligence (AI) model, to discover concrete formulas with desired properties. Our model is trained just using a small open dataset from the UCI Machine Learning Repository joined with environmental impact data from standard lifecycle analysis. Computational predictions demonstrate CVAEs can design concrete formulas with much lower carbon requirements than existing formulations while meeting design requirements. Next we report laboratory-based compressive strength experiments for five AI-generated formulations, which demonstrate that the formulations exceed design requirements. The resulting formulations were then used by Ozinga Ready Mix—a concrete supplier—to generate field-ready concrete formulations, based on local conditions and their expertise in concrete design.

Dangerous speech on social media platforms can be framed as blatantly inflammatory, or be couched in innuendo. It is also centrally tied to who engages it – it can be driven by openly sectarian social media accounts, or through subtle nudges by influential accounts, allowing for complex means of reinforcing vilification of marginalized groups, an increasingly significant problem in the media environment in the Global South. We identify dangerous speech by influential accounts on Twitter in India around three key events, examining both the language and networks of messaging that condones or actively promotes violence against vulnerable groups. We characterize dangerous speech users by assigning Danger Amplification Belief scores and show that dangerous users are more active on Twitter as compared to other users as well as most influential in the network, in terms of a larger following as well as volume of verified accounts. We find that dangerous users have a more polarized viewership, suggesting that their audience is more susceptible to incitement. Using a mix of network centrality measures and qualitative analysis, we find that most dangerous accounts tend to either be in mass media related occupations or allied with low-ranking, right-leaning politicians, and act as “broadcasters” in the network, where they are best positioned to spearhead the rapid dissemination of dangerous speech across the platform.
社交媒体平台上的危险言论可以被认为是公然煽动性的,或者是含沙射影的。它也与谁参与其中密切相关——它可以由公开的宗派社交媒体账户驱动,也可以通过有影响力的账户的微妙推动,允许以复杂的方式加强对边缘化群体的诋毁,这是全球南方媒体环境中日益严重的问题。我们识别了印度Twitter上有影响力的账户围绕三个关键事件发表的危险言论,检查了宽恕或积极促进针对弱势群体的暴力行为的语言和信息网络。我们通过分配危险放大信念分数来表征危险言论用户,并表明危险用户在Twitter上比其他用户更活跃,并且在网络中最有影响力,就更大的追随者和验证账户数量而言。我们发现,危险的用户有更两极分化的观众,这表明他们的观众更容易受到煽动。使用网络中心性测量和定性分析的混合方法,我们发现最危险的账户往往要么从事与大众媒体相关的职业,要么与低级右倾政客结盟,并在网络中充当“广播员”,在那里他们处于最有利的位置,可以率先在整个平台上快速传播危险言论。

Phone sharing is pervasive in many low- and middle-income countries, affecting how millions of people interact with technology and each other. Yet there is very little quantitative evidence available on the extent or nature of phone sharing in resource-constrained contexts. This paper provides a comprehensive quantitative analysis of demographic variation in phone sharing patterns in Togo, and documents how a large cash transfer program during the COVID-19 pandemic impacted sharing. We analyze mobile phone records from the entire Togolese mobile network to measure the movement of SIM cards between SIM card slots (often on different mobile devices). By matching phone sharing measures derived from SIM reshuffling to demographic data from a government-run cash transfer program covering hundreds of thousands of individuals, we find that phone sharing is most common among women, young people, and people in rural areas. We also leverage randomization in the cash transfer program to find that the delivery of cash aid via mobile money significantly increases phone sharing among beneficiaries. We discuss the limitations of measuring phone sharing with mobile network data and the implications of our results for future aid programs delivered via mobile money.
手机共享在许多低收入和中等收入国家很普遍,影响着数百万人与技术以及彼此之间的互动。然而,在资源有限的情况下,关于手机共享的程度或性质的定量证据很少。本文对多哥手机共享模式的人口差异进行了全面定量分析,并记录了2019冠状病毒病大流行期间的大规模现金转移支付计划如何影响手机共享。我们分析了来自整个多哥移动网络的移动电话记录,以测量SIM卡槽之间SIM卡的移动(通常在不同的移动设备上)。通过将SIM卡重组所得的手机共享指标与政府运营的覆盖数十万人的现金转移支付项目的人口统计数据相匹配,我们发现,手机共享在女性、年轻人和农村地区的人群中最为普遍。我们还利用现金转移计划中的随机化,发现通过移动货币提供现金援助显著增加了受益人之间的电话共享。我们讨论了用移动网络数据衡量手机共享的局限性,以及我们的结果对未来通过移动货币提供的援助项目的影响。
