{"title":"Resource Scarcity and Socially Just Internet Access over Time and Space","authors":"D. Pargman, Björn Wallsten","doi":"10.1145/3080556.3084083","DOIUrl":"https://doi.org/10.1145/3080556.3084083","url":null,"abstract":"Computing within Limits is concerned with \"the impact of present and future ecological, material, energetic, and societal limits on computing\". This paper discusses limits to computing by adopting a resource perspective on the provisioning of infrastructure for computing with a particular focus on present and future availability of material resources such as minerals and energy. While making claims about resources in general, we use copper as a specific example of coping with finiteness. The first part of the paper summarizes known facts but it is also a set-up for the latter part of the paper where we problematize the concept of \"innovation\" and argue that the term needs to be both refined and broadened to also take scarcity and just access to resources into account. We suggest that in a resource-constrained world and in the area of computing, a suitable goal for innovation should be to guarantee (to the largest extent possible) internet access over space and time, e.g., to the largest number of people and for the longest duration of time.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122934852","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}

We describe trends in sustainable interaction design. We ask four fundamental questions as a synthesis of SID and SDID, namely how can we reduce environmental harm now, alter practices to reduce environmental harm in the future, alter practices to promote a healthier society, and create new technology and practices to face future challenges? We relate these questions to frameworks of analysis in SID and SDID, as well as to transdisciplinary design. To illustrate the importance of these questions, we present and relate three conceptual design scenario discussions that may be characterized in human-centered terms of analysis as (a) finding balance, (b) resistance to technologies that push more consumption, and (c) observing a day of rest.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114412785","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}

Because those who suffer the most are often the most marginalized, these communities are largely neglected by governments and national media. In rich countries, social media has enabled ordinary citizens to add their voices to the public discourse. In the Global South, access to Internet and social media technologies is extremely constrained. In this paper, we study how, despite these barriers, communities in Bangladesh that are chronically affected by riverbank erosion are managing to use Facebook to participate in \"hashtag activism.\" This activism makes some progress toward filling the information gap regarding the impacts of riverbank erosion in Bangladesh, and can inform the national media and government for taking action.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129287312","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}

{"title":"The Story of Toxic Chemicals in Computing Systems","authors":"M. Diamond","doi":"10.1145/3080556.3080570","DOIUrl":"https://doi.org/10.1145/3080556.3080570","url":null,"abstract":"Protecting human and environmental health from the effects of toxic chemicals is an element of sustainability efforts and respecting global biophysical limits. Can this goal be achieved with respect to toxic chemicals used in computing systems? It is likely no surprise that achieving this goal is a wicked problem characterized by multiple disciplinary silos, knowledge gaps, competing priorities and vested interests, problems between organizational boundaries, the need to change human behavior and economic imperatives, and the unintended consequences of solutions. This talk unpacks the challenge of protecting human and environmental health with respect to (only) one set of chemicals used in computing systems, namely organic flame retardants (FRs). I chose FRs because they are used in all computing system hardware (e.g., cell phones, computer cases, printed circuit boards, wiring), but they migrate from their source polymer with disposition in global human and ecosystem populations. Studies continue to emerge that link exposure to specific FRs with adverse health effects including loss of IQ points and other neurological and neurobehavioral effects, and reproductive effects. The story unfolds with one family of flame retardants (polybrominated diphenyl ethers or PBDEs) that are found globally in human and ecosystem populations and that have been associated with adverse health impacts. PBDEs were widely used in the exterior cases and wiring of computing systems, as well as other uses such as the foam of upholstered furniture. The major source of human exposure was considered to be foam-containing products. In North America, controls on new uses were implemented for two PBDE formulations in 2004 and a third formulation in 2013 due to their toxicity and persistence. This resulted in decreasing concentrations in most environments with the important exception of those handling a poorly quantified mass of e-waste in developed and developing countries. Here, e-waste will continue to be a source of exposure to PBDEs for at least the next decade. A secondary source of exposure to PBDEs comes from new products (e.g., my plastic kitchen spoons) that were presumably manufactured from recycled PBDE-containing polymers such as computer cases.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122564522","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}

Over the past fifteen years there has been an exponential increase in wireless data usage, a trend that is predicted to continue. The overall capacity for wireless connectivity is limited in that it operates over electromagnetic spectrum, and the usable range of spectrum is both finite and already scarce. We argue that the growth in demand that we currently see is unsustainable in the long-term, as spectrum resources will become fully exhausted. While current lines of research seek to increase spectrum efficiency, increases in the future will achieve diminishing returns. In this work we present current technologies as well as cutting-edge research related to maximizing the efficiency of wireless systems, and offer research questions that will become critical as we near the limits of wireless connectivity.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134093787","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}

However, a 2015 study in Nature predicted that climate change will dramatically slow and redistribute growth in the coming decades. This paper explores how decreased and redistributed growth may impact future information systems and digital innovation. While a long-term global slowdown is not certain, different countries will likely experience significant changes in their growth trajectories, and resulting civilizational transformations. We seek to establish quantitative and theoretical foundations for how a future characterized by climate change would impact information systems around the globe.","PeriodicalId":133595,"journal":{"name":"Proceedings of the 2017 Workshop on Computing Within Limits","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131491279","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}
