An Alternative to India's Reservation Policy: A Unified Framework for Rigorous and Adaptive Measurement of Socio-Economic Status 印度保留政策的替代方案:社会经济地位严格和适应性衡量的统一框架
Dhruv Sinha, Ojas Sahasrabudhe, Dhruv Agarwal, Debayan Gupta
Affirmative action in the form of reservations is a divisive and contentious topic of policy in India. In this paper, we aim to create a principled and data-driven model to design the reservations policy in India. We look at some arguments against current policy and try to resolve them. We use statistical modeling to create our new framework, RAMSES (Rigorous and Adaptive Measurement of Socio-Economic Status). RAMSES measures the multidimensional disadvantage faced by an individual as an "adjusted income", which attempts to calibrate the quantum of compensatory aid in the form of reservations for that individual to have a level playing field. We illustrate our model using a case study.
保留形式的平权行动在印度是一个分裂和有争议的政策话题。在本文中,我们的目标是创建一个有原则和数据驱动的模型来设计印度的预订政策。我们着眼于一些反对当前政策的论点,并试图解决它们。我们使用统计建模来创建我们的新框架,RAMSES(严格和适应性的社会经济地位测量)。RAMSES以“调整后收入”来衡量个人面临的多维劣势,它试图以保留的形式校准补偿性援助的数量,以使个人拥有公平的竞争环境。我们使用一个案例研究来说明我们的模型。

Wildlife conservancies across the globe are increasingly recognizing their need to support their surrounding communities to sustainably operate. Rapidly shifting environmental and sociopolitical climates increasingly stress existing resource and service provisions, forcing wildlife conservancies to co-manage with local communities shared resources like water, wildlife, soil, pollinators, and security. This work presents a case study in Laikipia, Kenya on Ol Pejeta Conservancy's use of text-based technologies to provide services and build relationships with the many widely-dispersed communities on its borders. Through technology deployments, staff interviews, and community focus groups, we investigate a potential role for basic mobile phone services, like SMS and USSD, to help conservancy personnel disseminate accurate and timely information, gather community feedback, address grievances, and improve accountability. Our findings show that communication with locals requires intense and ongoing effort from conservancy staff. Partially successful deployments of phone services provide a proof-of-concept for their utility in community relations but highlight particular design challenges for wildlife conservancies; having critical needs for broad inclusive engagement; clear, deliberate communication; and careful trust-building.
世界各地的野生动物保护协会越来越认识到他们需要支持周围社区的可持续运作。快速变化的环境和社会政治气候对现有资源和服务供应的压力越来越大,迫使野生动物保护协会与当地社区共同管理水资源、野生动物、土壤、传粉媒介和安全等共享资源。这项工作介绍了一个在肯尼亚莱基皮亚的案例研究,关于奥佩杰塔保护协会使用基于文本的技术来提供服务,并与边界上许多广泛分布的社区建立关系。通过技术部署、员工访谈和社区焦点小组,我们调查了基本移动电话服务(如短信和USSD)在帮助管理人员传播准确及时的信息、收集社区反馈、解决不满和改善问责制方面的潜在作用。我们的研究结果表明,与当地人的沟通需要保护人员不断努力。电话服务的部分成功部署为其在社区关系中的效用提供了概念验证,但突出了野生动物保护的特殊设计挑战;迫切需要广泛的包容性参与;清晰、深思熟虑的沟通;小心地建立信任。

RoadCare
Saurabh Tiwari, Ravi Bhandari, B. Raman
Roads form a critical part of any region's infrastructure. Their constant monitoring and maintenance is thus essential. Traditional monitoring mechanisms are heavy-weight, and hence have insufficient coverage. In this paper, we explore the use of crowd-sourced intelligent measurements from commuters' smart-phone sensors. Specifically, we propose a deep-learning based approach to road surface quality monitoring, using accelerometer and GPS sensor readings. Through extensive data collection of over 36 hours on different kinds of roads, and subsequent evaluation based on this, we show that the approach can achieve high accuracy (98.5%) in a three-way classification of road surface quality. We also show how the classification can be extended to a finer grained 11-point scale of road quality. The model is also efficient: it can be implemented on today's smart-phones, thus making it practical. Our approach, called RoadCare, enables several useful smart-city applications such as spatio-temporal monitoring of the city's roads, early warning of bad road conditions, as well as choosing the "smoothest" road route to a destination.

Enhancing Seismic Resilience of Water Pipe Networks 提高供水管网的抗震能力
Taoan Huang, B. Dilkina
As disasters such as earthquakes and floods become more frequent and detrimental, it is increasingly important that water infrastructure resilience be strategically enhanced to support post-disaster functionality and recovery. In this paper, we focus on the problem of strategically building seismic-resilient pipe networks to ensure direct water supply to critical customers and certain proximity to water sources for residential areas, which we formalize as the Steiner Network Problem with Coverage Constraints. We provide complexity statements of the problem and present an efficient mixed-integer linear program encoding to solve the problem. We also investigate the problem of planning partial network installments to maximize efficiency over time and propose a fast and effective sequential planning algorithm to solve it. We evaluate our algorithms on synthetic water networks and also apply them to a case study on a water service zone in Los Angeles, which demonstrate the effectiveness of our methods for large-scale real-world applications.
随着地震和洪水等灾害变得更加频繁和有害,从战略上加强水利基础设施的复原力以支持灾后功能和恢复变得越来越重要。在本文中,我们重点研究战略性地建设地震弹性管网的问题,以确保直接向关键客户供水,并在一定程度上接近居民区的水源,我们将其形式化为具有覆盖约束的斯坦纳网络问题。我们给出了该问题的复杂性表述,并提出了一种有效的混合整数线性程序编码来解决该问题。我们还研究了局部网络安装的规划问题,以最大限度地提高效率,并提出了一个快速有效的顺序规划算法来解决这个问题。我们在合成供水网络上评估了我们的算法,并将其应用于洛杉矶供水服务区的案例研究,这证明了我们的方法在大规模实际应用中的有效性。

COVID-19 on Facebook Ads: Competing Agendas around a Public Health Crisis Facebook广告上的COVID-19:围绕公共卫生危机的竞争议程
Yelena Mejova, Kyriaki Kalimeri
In the age of social media, disasters and epidemics usher not only devastation and affliction in the physical world, but also prompt a deluge of information, opinions, prognoses and advice to billions of internet users. The coronavirus epidemic of 2019-2020, or COVID-19, is no exception, with the World Health Organization warning of a possible 'infodemic' of fake news. In this study, we examine the alternative narratives around the coronavirus outbreak through advertisements promoted on Facebook, the largest social media platform in the US. Using the new Facebook Ads Library, we discover advertisers from public health and non-profit sectors, alongside those from news media, politics, and business, incorporating coronavirus into their messaging and agenda. We find the virus used in political attacks, donation solicitations, business promotion, stock market advice, and animal rights campaigning. Among these, we find several instances of possible misinformation, ranging from bioweapons conspiracy theories to unverifiable claims by politicians, to the sale of face masks which may not necessarily protect the wearer. As we make the dataset available to the community, we hope the advertising domain will become an important part of quality control for public health communication and public discourse in general.
在社交媒体时代,灾难和流行病不仅给现实世界带来破坏和痛苦,而且还促使数十亿互联网用户获得大量信息、意见、预测和建议。2019-2020年的冠状病毒疫情(COVID-19)也不例外,世界卫生组织警告称,可能出现假新闻的“信息大流行”。在这项研究中,我们通过在美国最大的社交媒体平台Facebook上宣传的广告,研究了围绕冠状病毒爆发的不同叙事。使用新的Facebook广告库,我们发现来自公共卫生和非营利部门的广告商,以及来自新闻媒体、政治和商业的广告商,他们将冠状病毒纳入他们的信息和议程。我们发现这种病毒被用于政治攻击、募捐、商业推广、股票市场咨询和动物权利运动。其中,我们发现了几个可能存在错误信息的例子,从生物武器阴谋论到政客们无法证实的说法,再到口罩的销售,这些口罩不一定能保护佩戴者。随着我们将数据集提供给社区,我们希望广告领域将成为公共卫生传播和公共话语质量控制的重要组成部分。

Can crowdsourcing create the missing crash data? 众包能创造缺失的坠机数据吗?
S. Milusheva, R. Marty, Guadalupe Bedoya, Elizabeth Resor, Sarah Williams, Arianna Legovini
UPDATED---June 1, 2020. Road traffic crashes (RTCs) are the primary cause of death among children and young adults. Yet data on RTCs is incomplete, hindering effective road safety policymaking in many developing countries where mortality is purportedly highest. We web-scrape 850,000 tweets to create crash data and develop a machine learning algorithm to geolocate RTCs. Our algorithm is nearly twice as precise as a standard geoparsing algorithm in identifying the set of locations that include the crash location. Above and beyond, it identifies the unique location of a crash from the set of possible locations in a majority of cases. We dispatch a set of motorcycle drivers to the site of the presumed crash in real time to verify the validity of the crowdsourced data and document the performance of the algorithm. The study can be used as a proof of concept for countries interested to improve RTC data at low cost through a machine learning approach and substantially increase the data available to analyze RTCs and prioritize road safety policies.
更新至2020年6月1日。道路交通事故是儿童和青年死亡的主要原因。然而,关于rtc的数据不完整,阻碍了许多据称死亡率最高的发展中国家有效的道路安全政策制定。我们从网上抓取了85万条推文来创建崩溃数据,并开发了一种机器学习算法来定位rtc。在识别包括坠机地点在内的一系列地点方面,我们的算法几乎是标准地质解析算法的两倍。除此之外,在大多数情况下,它从一组可能的位置中识别出崩溃的唯一位置。我们派遣一组摩托车司机到假定的撞车现场实时验证众包数据的有效性,并记录算法的性能。对于有兴趣通过机器学习方法以低成本改进RTC数据的国家来说,这项研究可以作为一种概念证明,并大幅增加可用于分析RTC和优先考虑道路安全政策的数据。

Practitioners and ICTD: Communities of Practice Theory in Technology Interventionism 实践者与ICTD:技术干预主义的实践理论共同体
Anthony Poon
ICTD is a field with a long history of interventionist research in a broad set of domains, including health, agriculture, education, and civics. A common thread between many of these interventions is that they addressed the knowledge and actions of practitioners who were engaged in development activities in their contexts. In this paper, I survey the past literature of ICTD interventions targeting practitioners to identify a common typology that spans domain and context. I use Lave and Wenger's Communities of Practice (CoP) theory as a way to understand the situated and social aspects of practice and describe how ICTD interventions have often engaged with such communities. I discuss how a CoP lens may intersect with other theoretical lenses in ICTD and related fields, specifically around concepts of agency, intrinsic motivation, amplification, and sustainability. I describe how such intersections may inform future interventionist research in the Global South.
ICTD是一个在包括卫生、农业、教育和公民在内的一系列广泛领域进行干预主义研究的历史悠久的领域。许多这些干预措施之间的一个共同点是,它们针对的是在其背景下从事发展活动的从业人员的知识和行动。在本文中,我调查了过去针对从业者的ICTD干预的文献,以确定跨越领域和背景的共同类型。我使用Lave和Wenger的实践社区(CoP)理论来理解实践的情境和社会方面,并描述ICTD干预措施如何经常与这些社区接触。我将讨论CoP视角如何与ICTD及相关领域的其他理论视角相交,特别是围绕代理、内在动机、放大和可持续性等概念。我描述了这些交叉点如何为未来全球南方的干预主义研究提供信息。

Approaches to Understanding Indigenous Content Production on Wikipedia 理解维基百科本地内容生产的方法
Manasvini Sethuraman, Rebecca E. Grinter, E. Zegura
With over 6 million articles and 38 million editors, English Wikipedia is one of the largest peer produced and edited encyclopedias on the Internet. Some attribute this success to the peer production process which allows many to contribute. However, not all articles are created equally, or evolve similarly, in terms of quality and amount of attention they receive from the editing community. We examine pages with geotagged content in English Wikipedia in four categories, places with Indigenous majorities (of any size), Rural places, Urban Clusters, and Urban areas. We find significant differences in quality and editor attention for articles about places with Native American majorities, as compared to other places.
英文维基百科拥有超过600万篇文章和3800万编辑,是互联网上最大的同行制作和编辑的百科全书之一。一些人将这种成功归因于允许许多人贡献的对等生产过程。然而,并不是所有的文章都是平等的,或者在质量和从编辑社区获得的关注量方面都是相似的。我们将英语维基百科中带有地理标记内容的页面分为四类:土著居民占多数的地方(任何规模)、农村地区、城市集群和城市地区。我们发现,与其他地方相比,关于印第安人占多数地区的文章在质量和编辑注意力方面存在显著差异。

The Role of In-Group Bias and Balanced Data: A Comparison of Human and Machine Recidivism Risk Predictions 群体内偏见和平衡数据的作用:人类和机器再犯风险预测的比较
Arpita Biswas, M. Kołczyńska, Saana Rantanen, Polina Rozenshtein
Fairness and bias in automated decision-making gain importance as the prevalence of algorithms increases in different areas of social life. This paper contributes to the discussion of algorithmic fairness with a crowdsourced vignette survey on recidivism risk assessment, which we compare to previous studies on this topic and to predictions of an automated recidivism risk tool. We use the case of the Correctional Offender Management Profiling for Alternative Sanctions (COMPAS) and the Broward County dataset of pre-trial defendants as a data source and for purposes of comparability with the earlier analysis. In our survey, each respondent assessed recidivism risk for a set of vignettes describing real defendants, where each set was balanced with regard to the defendants' race and re-offender status. The survey ensured a 50: 50 ratio of black and white respondents. We found that predictions in our survey---while less accurate---were considerably more fair in terms of equalized odds than previous surveys. We attribute it to the differences in survey design: using the balanced set of vignettes and not providing feedback after responding to each vignette. We also analyzed the performance and fairness of predictions by race of respondent and defendant. We found that both white and black respondents tend to favor defendants of their own race, but the magnitude of the effect is relatively small. In addition to the survey, we train two statistical models, one trained with balanced data and other with unbalanced data. We observe that the model trained on balanced data is substantially more fair and possess less in-group bias.
随着算法在社会生活不同领域的普及,自动决策中的公平性和偏见变得越来越重要。本文通过对累犯风险评估的众包调查来讨论算法公平性,并将其与先前关于该主题的研究和自动累犯风险工具的预测进行了比较。为了与之前的分析比较,我们使用了惩教罪犯管理分析替代制裁(COMPAS)案例和布劳沃德县审前被告数据集作为数据来源。在我们的调查中,每个受访者评估了一组描述真实被告的小插曲的再犯风险,其中每一组都是根据被告的种族和再犯身份进行平衡的。该调查确保了黑人和白人受访者的比例为50:50。我们发现,我们调查中的预测虽然不那么准确,但就平均赔率而言,比以前的调查要公平得多。我们将其归因于调查设计的差异:使用平衡的小插曲集,而不是在回应每个小插曲后提供反馈。我们还根据被告和被告的种族分析了预测的效果和公平性。我们发现,白人和黑人受访者都倾向于支持自己种族的被告,但影响的幅度相对较小。除了调查之外,我们还训练了两个统计模型,一个是用平衡数据训练的,另一个是用不平衡数据训练的。我们观察到,在平衡数据上训练的模型实质上更公平,并且具有更少的群体内偏见。

This paper contributes to the discussion of algorithmic fairness with a crowdsourced vignette survey on recidivism risk assessment, which we compare to previous studies on this topic and to predictions of an automated recidivism risk tool. We use the case of the Correctional Offender Management Profiling for Alternative Sanctions (COMPAS) and the Broward County dataset of pre-trial defendants as a data source and for purposes of comparability with the earlier analysis. In our survey, each respondent assessed recidivism risk for a set of vignettes describing real defendants, where each set was balanced with regard to the defendants' race and re-offender status. The survey ensured a 50: 50 ratio of black and white respondents. We found that predictions in our survey---while less accurate---were considerably more fair in terms of equalized odds than previous surveys. We attribute it to the differences in survey design: using the balanced set of vignettes and not providing feedback after responding to each vignette. We also analyzed the performance and fairness of predictions by race of respondent and defendant. We found that both white and black respondents tend to favor defendants of their own race, but the magnitude of the effect is relatively small. In addition to the survey, we train two statistical models, one trained with balanced data and other with unbalanced data. We observe that the model trained on balanced data is substantially more fair and possess less in-group bias.","PeriodicalId":176951,"journal":{"name":"Proceedings of the 3rd ACM SIGCAS Conference on Computing and Sustainable Societies","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124918082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of urban infrastructure development on female labour force participation among the poor and middle class in India 城市基础设施发展对印度贫困和中产阶级女性劳动力参与的影响
Ahalya Ramanathan, S. Paul
In this paper, the impact of urban infrastructure investment on female labour force participation is studied for different income groups, namely, the poor, the lower class, and the middle class. In particular, the effect of government spending on water supply/sanitation, buses, and basic household services, under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) on female labour force participation is assessed. A probit regression model, over a pooled cross sectional dataset at the district level is used for the analysis. Female labour force participation is the categorical dependent variable, while government spending on the infrastructure scheme is the main explanatory variable. The results indicate that investment on water supply and sanitation facilities in a district has a positive effect on female labour force participation among middle class women, but not on lower class women. The expenditure on dwellings, and basic services, discourages female labour force participation among poor women. The paper throws light on the role of class in determining the effect of urban infrastructure programs on female labour force participation. It shows that the poor women are not driven into labour force due to lesser burden of household chores in the presence of better water supply, and sanitation facilities, and the urban housing programs alienate poor women from job opportunities, while encouraging middle class women to participate in the labour force due to the creation of a slum free, and supposedly safe environment.
本文研究了城市基础设施投资对不同收入群体,即穷人、下层阶级和中产阶级女性劳动力参与的影响。特别是评估了政府在贾瓦哈拉尔·尼赫鲁全国城市重建任务下在供水/卫生、公共汽车和基本家庭服务方面的支出对女性劳动力参与的影响。一个概率回归模型,在一个汇集的横截面数据集在地区一级被用于分析。女性劳动力参与率是绝对的因变量,而政府在基础设施计划上的支出是主要的解释变量。结果表明,一个地区对供水和卫生设施的投资对中产阶级妇女的女性劳动力参与有积极影响,但对下层妇女没有积极影响。住房和基本服务方面的支出阻碍了贫穷妇女参与劳动。这篇论文揭示了阶级在决定城市基础设施项目对女性劳动力参与的影响方面所起的作用。研究表明,贫困妇女没有被迫进入劳动力市场,因为在有更好的供水和卫生设施的情况下,家务负担较轻,城市住房计划使贫困妇女远离就业机会,同时由于创造了一个无贫民窟的、据称安全的环境,鼓励中产阶级妇女参与劳动力市场。
