Center for Earth Systems Engineering and Management


A collection of scholarly work published by and supporting the Center for Earth Systems Engineering and Management (CESEM) at Arizona State University.

CESEM focuses on "earth systems engineering and management," providing a basis for understanding, designing, and managing the complex integrated built/human/natural systems that increasingly characterize our planet.

Works in this collection are particularly important in linking engineering, technology, and sustainability, and are increasingly intertwined with the work of ASU's Global Institute of Sustainability (GIOS).

In the construction industry the management of knowledge is becoming an increasingly important element for success. The successful management of knowledge helps general contractors to better compete which ultimately leads to more contracts and potentially greater prots. The Life Cycle Costing assessment presented here, is a small step in understanding the complex decision of investing in BIM from general contractor's perspective. This assessment has identified the cost components for BIM and has allocated the cost for a typical project.

While the scientific study of religion is not new, the topic has yet to be approached by Lifecycle Assessment (LCA). This work demonstrates a method for assessing the personal “cost” of “manufacturing” a mature religious adherent, or, a believer committed to a particular faith. By measuring such inputs as personal importance of faith, prayer, religious service attendance, religious experiences, and scripture reading, an assessment can be made of the quantity of such inputs required to engender enduring religious devotion. Ultimately, this study has demonstrated that the data typically collected in longitudinal surveys are insufficient to adequately support any firm quantitative …

An inter-temporal life cycle cost and greenhouse gas emissions assessment of the Los Angeles roadway network is developed to identify how construction decisions lead to embedded impacts and create an emergent behavior (vehicle miles traveled by users) in the long run. A video of the growth of the network and additional information are available at www.transportationlca.org/losangelesroadways/

In recent years, concerns have grown over the risks posed by climate change on the U.S. electricity grid. The availability of water resources is integral to the production of electric power, and droughts are expected to become more frequent, severe, and longer-lasting over the course of the twenty-first century. The American Southwest, in particular, is expected to experience large deficits in streamflow. Studies on the Colorado River anticipate streamflow declines of 20-45% by 2050. Other climactic shifts—such as higher water and air temperatures—may also adversely affect power generation. As extreme weather becomes more common, better methods are needed to assess …

This report updates Supplementary Information section 2.1.2.2 (Recirculating Cooling) of Bartos and Chester (2015). Extraneous derivations have been removed and an error corrected. Impacts of Climate Change on Electric Power Supply in the Western U.S., Matthew Bartos and Mikhail Chester, Nature Climate Change, 2015, 4(8), pp. 748-752, doi: 10.1038/nclimate2648, http://www.nature.com/nclimate/journal/v5/n8/full/nclimate2648.html

The goal of this working paper is to provide the methodological background for several upcoming reports and peer-reviewed journal publications. This manuscript only provides background methodology and does not show or interpret any of the results that are being generated by the research team. The methodology is consistent with the transportation LCA approach developed by the author in previous research. The discussion in this working paper provides the detailed background data and steps used by the research team for their assessment of Los Angeles Metro transit lines and a competing automobile trip.

Building energy assessment often focuses on the use of electricity and natural gas during the use phase of a structure while ignoring the energy investments necessary to construct the facility. This research develops a methodology for quantifying the “embedded” energy and greenhouse gases (GHG) in the building infrastructure of an entire metropolitan region. “Embedded” energy and GHGs refer to the energy necessary to manufacture materials and construct the infrastructure. Using these methods, a case study is developed for Los Angeles County.

Most would agree that telecommunications systems are socially constructed. Since “communication” tends to involve people, it seems obvious that people should impact the creation of such systems. But it is far less obvious that the specifications for such systems should be noted for their social construction. As marvelous and technical as the system is, we must not forget the important technological artifact known as the specification that came before it. This paper tells the story of the social construction of the IRIDIUM system specification as viewed through the eyes of a popular socio-technical systems (STS) analysis tool. Actor-Network Theory (ANT) …

Essay scoring is a difficult and contentious business. The problem is exacerbated when there are no “right” answers for the essay prompts. This research developed a simple toolset for essay analysis by integrating a freely available Latent Dirichlet Allocation (LDA) implementation into a homegrown assessment assistant. The complexity of the essay assessment problem is demonstrated and illustrated with a representative collection of open-ended essays. This research also explores the use of “expert vectors” or “keyword essays” for maximizing the utility of LDA with small corpora. While, by itself, LDA appears insufficient for adequately scoring essays, it is quite capable of …
