Quantified Self for Sustainability (paper)

The topic of my two previous blog post were papers that we submitted to the upcoming ICT for Sustainability (ICT4S) conference. This blog post is about yet another paper I submitted to that same conference (the third and last). The paper "Quantified Self for Sustainability: Limitations and Possibilities" is written by Björn Hedin, Daniel Pargman and Miriam Börjesson Rivera. We are all at the KTH Royal Institute of Technology but while me and Björn work at the School of Computer Science and Communication, Miriam work at the School of Architecture and the Built Environment. Me and Miriam have on the other hand sat next to each other at the premises of the Center for Sustainable Communication (CESC) for the better part of two years while Björn sits at the Department of Media Technology and Interaction Design (MID) - one floor above from me and Miriam.

The paper primarily builds on the first two authors' work in the project "Improved energy counseling and energy habits by Quantified Self Assisted Advisory". This paper does however not report on the results of any particular project but is rather a synthesis of us thinking about quantified self (QS) for a long time and in may sub-projects. The main contribution of the paper is the presentation of a framework "which can be used to develop and assess QS solutions". We really think we are on to something but it could be that we could sharpen the discussion and the conclusions further (it was a bit hectic in the end).

Quantified Self for Sustainability: Limitations and Possibilities

Quantified self has been described as “any individual engaged in the self-tracking of any kind of biological, physical, behavioral, or environmental information” in order to obtain information and act upon it. Some aspects of our lives such as walking is easy to track, for example by using a step counter. Other aspects such as greenhouse gas emissions (CO2e) generated by different decisions in our everyday lives are much harder to track. Such aspects must instead be derived from other data sources, such as when calculating CO2e emitted when driving a car, or from eating a meal. The transformations that are required are in most cases based on templates, simplifications and assumptions that all introduce uncertainties, making the results deceptively precise. In this paper, we present a framework that can be used to understand and express these uncertainties. The framework highlights limitations of how derived data can be used and what can and cannot be framed as “facts” with a reasonable degree of certainty. However, by explicitly acknowledging and presenting the reasons for the uncertainty, we argue that Quantified Self can - with proper knowledge of its strengths and weaknesses - be a powerful tool for reflective learning and pro-environmental behavior change.

  1. My husband and I have been having lots of problems living together, he never gives me attention or makes me happy because he has fallen in love with another woman outside our marriage. I tried my best to make sure that my husband leaves this woman but the more I talk to him about it the more he makes me feel sad and unhappy, My marriage started leading to divorce because he no longer gives me attention. I wanted to forget him but i love him and didn't want to lose him. We have been married for years and he is all I could call a true best friend and best in all, the man that handles my problems perfectly, the man that makes sacrifices for ,my happiness. I wanted him back in my life badly and I was so confused. My Friends told me to buy books about relationships, so I went online for relationship books while I came across a spell caster called Dr Emu. I read testimonies and reviews about him so I contacted him immediately, explained my problems to him. Same day , he casted a spell for me and assured me for 2 days that my husband will return to me and to my greatest surprise the third day my husband came knocking on my door and begged for forgiveness. I am so happy that my love is back again and not only that, we are about to get married again, he proposed. I wouldn't stop talking about him. Contact him today if you need his help via email: emutemple@gmail.com and you will see that your problem will be solved without any delay. Website: https://emutemple.wordpress.com/
