In: Arsenic Research and Global Sustainability - Proceedings of the 6th International Congress on Arsenic in the Environment, AS 2016. - : CRC Press/Balkema. - 9781138029415 ; , s. 632-633

Conference paper (peer-reviewed)abstract
- The development of a simple and low cost technique for determination of arsenic (As) in drinking water wells is an urgent need to accelerate As mitigation policy. The aim of this study was to evaluate the potentiality of tubewell platform color as low-cost, quick and convenient screening tool for As. The result shows strong correlation between the development of red color stain on tubewells platform and As enrichment in the corresponding tubewells water compared to WHO (10 μg/L) and BDWS (50 μg/L), with 99% certainty. The red color stain in the platform indicates 98% sensitivity with WHO (10 μg/L) and BDWS (50 μg/L). With regard to WHO and BDWS, the corresponding efficiency of the platform color as screening tool for As are 97.3% and 97%. This study suggests that platform color can be potentially used for screening tubewells, help users switch to tube wells with low As and facilitate sustainable As mitigation efforts in developing countries.

A multiple ownerships diffusion model of cellular service: A study of the Swedish market
- 2011
-
In: 2nd ITS PhD symposium, Budapest. September 22-23.
-
Conference paper (other academic/artistic)abstract
- Cellular service diffusion has been widely explained using classic diffusion modeling which uses the accumulated number of subscriptions or possession of active SIM cards -often known as the cellular phone penetration rate- as the proxy. Such approach tends to overlook the presence of cellular service multiple-subscriptions as well as the problematic inaccuracies of cellular service penetration rate as the proxy. As an alternative, the present study explains the diffusion of cellular service using multiple ownerships diffusion models with longitudinal cross-section data as the proxy. Based on curve-fit estimation of the model using data obtained from nation-wide survey during 2002-2010, this study found that diffusion of cellular service with single subscriptions have higher innovation coefficient but lower imitation coefficient than one with multiple subscriptions. This indicates that the nature of demand for additional subscriptions may be different than that for first subscriptions and therefore the trend of growth should be estimated separately. Further, the multiple-unit ownership diffusion modeling offers more advantages than classic diffusion modeling as it can indicate the percentage of cellular service non-adopters in a population which can be estimated by examining the trend of cellular service adopters with single subscriptions to the population trend. The model also has a more intuitive forecasting power as it also distinguishes the growth trend projection for each type of adopters.

Energy infrastructure and the fate of the nation: Introduction to special issue
- 2018
-
In: Energy Research & Social Science. - : Elsevier. - 2214-6296 .- 2214-6326. ; 41, s. 1-11

Journal article (peer-reviewed)abstract
- In this article we introduce a Special Issue of Energy Research and Social Science focused on energy infrastructure and the political economy of national development. Many countries are experiencing transformational growth in energy infrastructure, such as transmission and distribution systems; import, export and storage facilities; the development of domestic energy resources; and construction of new power generating stations based on wind, water, coal, gas and nuclear sources. Large-scale projects like these are frequently justified by appeals to grand narratives – promoting economic growth, securing energy supply, modernizing energy service provision, and transitioning to more environmentally sustainable energy systems - in which the fate of the nation is closely tied to infrastructural development. The papers in this collection present compelling empirical evidence of how claims for energy infrastructure’s national significance and/or necessity intersect with the (re)production of political and economic power. Drawing on case material from Africa, the Americas, Asia, Australia and Europe, they highlight the capacity of different energy technologies and infrastructural assemblages to shape political and economic outcomes beyond their role in storing, transporting or transforming energy. This Introduction to the Special Issue does three things. First, it characterises the scale and significance of the contemporary ‘infrastructural moment’, observing how, in many national contexts, energy policy-making remains centralised and divorced from public participation. Second, it critically differentiates existing literature on the political economy of energy infrastructure to identify five distinctive ways in which research understands the ‘political work’ infrastructure performs. Third, it introduces the papers in the Special Issue and organises them into four key themes. Overall, the Introduction affirms the importance for social science of understanding the economically and politically constitutive power of energy infrastructures. The critical reflexivity this requires is essential to moving towards energy infrastructures that are just, equitable and sustainable.
