Unfortunately, an essential part of this life cycle assessment method, col- lecting inventory data, is extremely time consuming. The quality of manually conducted LCA studies is often limited by uncertainty in the inventory data or narrow scope. Past attempts to overcome these challenges through automation of data collection utilizing the Internet of Things have relied on fully centralized architectures. The drawback of a central repository is the complex coordination between all involved actors in supply chains of products and services. This paper proposes an alternative hybrid approach combining a primary distributed system supplemented with a central repository reducing the need for coordination. This hybrid approach is named \"the Footprint of Things\". We present a system design that embeds the automatic reporting of life cycle inventory data, such as energy and material flows, into all product components involved in a service delivery. The major strength of our novel system design, among others, is its capacity for real-time and more precise impact calculation of ICT services.","PeriodicalId":149859,"journal":{"name":"ICT for Sustainability","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133383462","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}

How to improve it, however, still lacks evidence. Specifically, the impact of code smell refactoring on energy efficiency has been scarcely investigated. In the pilot study here reported, we investigate the impact on performance and energy consumption of refactoring well-known code smells on Java software applications. In order to understand if software metrics can be used as indicators of the energy impact of refactoring, we also measured the variation caused by refactoring on a set of well-established software metrics. We conducted a controlled experiment using state-of-the-art power measurement equipment. Statistical hypothesis testing and effect size estimation were performed on the experimental results. Results show that in one out of three applications, refactoring each smell significantly impacted power- and energy consumption. Specifically, refactoring Feature Envy and Long Method smells led to a 49% energy efficiency improvement. No software metrics significantly correlated with execution time, power or energy consumption. In conclusion, refactoring code smells can significantly improve software energy efficiency. The magnitude of the impact may depend on application properties, e.g. size or age. Further research is needed to understand the relationship between software metrics and energy efficiency.","PeriodicalId":149859,"journal":{"name":"ICT for Sustainability","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115185573","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}

Recognizing that information and communication technology (ICT) is shaping our modern society, there is a need to understand the impact of ICT on sustainability. On the one hand this can be achieved, for example, by extending classic software development approaches to cover sustainability issues. This can be coined sustainability in ICT . On the other hand, innovative ICT approaches oﬀer the potential of directly addressing sustainability issues ( sustainability by ICT ). Within the ICT4S community, both perspectives are addressed. What is missing, is an overarching perspective that helps to identify interlinkages. In this contribution, we present the case of an online-shop selling ICT hardware products as an community exemplar. We exemplify the usefulness as an overarching example, by relating parts of our existing work on ICT sustainability to it: a process model of the sales process, as well as a representation of sustainability risks related to the sold ICT products. Additionally, we show how ICT4S papers from 2016 can be mapped to the exemplar. We conclude with presenting a community website, where we invite fellow researchers and practitioners to contribute to a growing wealth of sustainability insights.","PeriodicalId":149859,"journal":{"name":"ICT for Sustainability","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123326532","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}

In recent years, social changes mediated by the development of information and communication technologies have pivoted new types of civic actions, which have enabled an expansion in the breath of citizen science applications. This civic technology has become a genuine interactive and inclusive opportunity for engaging citizens in the continuous collection of data relevant to science, governance, businesses, communal living, as well as individual concerns. This article presents the practices, trends and challenges of 108 ICT enabled citizen science projects. In addition, we present a palette for participation in ICT enabled citizen science that depicts the shapes civic participation is currently taking in different contexts. We discuss the potential uses of this palette for improving the engineering of ICT citizen science platforms to better fit the needs of volunteers and build opportunities for active engagement.

Despite this, previous research has highlighted that our rather excessive Internet use is not sustainable or even always socially beneficial. In this paper, we carried out an exploratory study on how Internet disconnection affects our everyday lives and whether such disconnection is even possible in today’s society. Through daily surveys, we captured what Internet use means for ten participants and how this varies when they are asked to disconnect by default, and re-connect only when their Internet use is deemed as necessary. From our study, we found that our participants could disconnect from the Internet for certain activities (particularly leisure focused), yet they developed adaptations in their lives to address the necessity of their Internet use. We elicit these adaptations into five themes that encompass how the participants did, or did not, use the Internet based on their necessities. Drawing on these five themes, we conclude with ways in which our study can inspire future research surrounding: Internet infrastructure limits; the promotion of slow values; Internet non-use; and the undesign of Internet services.","PeriodicalId":149859,"journal":{"name":"ICT for Sustainability","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115551774","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}
