Journal - Energy Policy

While the journal I have chosen isn’t only for media technology, it do in fact contain it from time to time. I believe the environment is an important field where Media Technology and ICT can make a difference, as the video example at the end showcases. The journal have an impact factor of 2.7 and 5-year impact factor of 3.2 which is quite good. Although this is part due to the fact that they don’t only publish in the field of ICT, which obviously means that they can get a broader citation. Nevertheless, I think this journal is both fitting and very interesting.

Paper - Making energy visible: A qualitative field study of how householders interact with feedback from smart energy monitors

Published in Energy Policy, this particular academic paper have an impact factor of 54 according to the google scholar ratio. The paper, by Tom Hargreaves, Michael Nye and Jacquelin Burgess, is a qualitative study of household energy consumption. For a year selected households in the UK participated in a trial where they tested the effects of having monitors which displayed their energy consumption. They tried three different monitors, which differed regarding how much information that was displayed. It went from low to high information flow and different kinds of capabilities of the monitors.The most advanced one could display 100 individual units. The study is very much like the now ongoing trials of the swedish enerfy company E.ON called “Sveriges största energisparexperiment” (which can be found [in swedish] on http://experimentet.eon.se/#nyheter).


I’ll focus my critic on the findings.

To analyze the findings, they used a method called grounded theory. From my understanding, grounded theory is a way to make a relation between different qualitative data and from that formulate a hypothesis for the research. So it’s kind of opposite of traditional research. Anyhow, I think that they present the data in a way that is easily understandable. They first describe the general consensus and then point it out with a quote from the interviews. The data is selective and only showing small parts of what they have, but I think that is understandable when dealing with qualitative data, especially interviews. It isn’t easy making it understandable for the reader, and you do really get a lot of data during interviews. I think they have made a good selection of what data to show. In conclusion, they did an ok job for nine (9) pages.



Questions


  1. Sense-data is the data with which we perceive the world, eg sound, touch, sight etc.

  2. Proposition is when we know facts about an object without knowing the said object in person. Statement of fact is similar; it instead deals with properties which we are familiar with, particular and universal. In general, these two concepts deal with knowledge/facts that we ourself don’t necessarily have experienced, which is the way they differentiate from other verbal expressions.

  3. “a phrase of the form 'the so-and-so' (in the singular) I shall call a 'definite' description”. My interpretation of definite description is that it means that a person or an object, and only that, have a qualitative of some sort.

  4. The main points for chapter 13 is that the more points provided for a fact, the more likelihood of it being true is higher; also, the more something is alike another, the more doubt you’ll have about the differences. The main points of chapter 14 is that philosophy have many similarities with other sciences, but differentiates in the fact that it is very self-doubting. The second important point of the chapter is that we as a species don’t have the true abillity to know the world a priori at this point in time.

  1. Visualizing energy consumption is a popular subject at the moment, with more and more global issues regarding our use of fossil fuels. You mention that the authors seleted specific data from what they collected. I think that it is important to at least ,in some way, show or describe what type of data that they left out in the paper, to make it clear that they are not biased in any sense. As you mention, it's not possible to show all the data, but if they only show some data, you might wonder what they left out and how that data would have affected the discussion and conclusions.

    1. I think this is a problem with all journal published in the field of media technology/ICT; you can only show so much in the span of 10-20 pages. Maybe if you ask they let you see all the data, but that really depends on how they or if they have anonymized the data.

  3. I have never heard of the concept Grounded theory before reading this blogpost. After looking up the term's definition, it appears to me that the methodology of grounded theory is actually based simply on empirical research. It does not have to focus on qualitative data only, it could also be applied to qualitative data. As you say, grounded theory works in the opposite direction compared to normal scientific research. One could ask why the authors do not choose to call it an empirical study based on reverse engineering?

    1. Rule of cool. Seriously though, I think it is because the orignal crafters of this methodology wanted a name that implies that the theory you come up with has it ground in empirical data. Or something. I don't really know!

  4. It would be nice to read about the results from the study, as it was a subject we discussed during previous sustainability course. Do the energy consumption decrease with this kind of energy visualization? Grounded theory is a new word for me too, good to know it's meaning!

    1. When/if you have the time, you can search for the paper at kth.se/kthb (primo). It should be the first result.
