Understanding Risk Perception Using Fuzzy Cognitive Maps, Pei Zhang, Antoine J. Jetter

Engineering and Technology Management Faculty Publications and Presentations

When making decision that can have far-researching effects, such as governmental policies or decisions on new technologies, decision-makers use their understanding of the risks that are associated with their choices to guide their decisions. Measuring how people perceive risks can be helpful for understanding and possibly improving the decision-making process. Building on a review of existing methods for investigating risk perceptions, this paper suggests Fuzzy Cognitive Maps (FCM) as a method for investigating differences in risk perception among stakeholders and stakeholder groups. The approach is illustrated with an example of wildfire risk perceptions. Results suggest that FCM can contribute to …

Improving Carbon Efficiency Through Container Size Optimization And Shipment Consolidation, Nang Laik Ma, Kar Way Tan, Edwin Lik Ming Chong

Research Collection School Of Computing and Information Systems

Purpose: Many manufacturing companies that ship goods through full container loads found themselves under-utilizing the containers and resulting in higher carbon footprint per volume shipment. One of the reasons is the choice of non-ideal container sizes for their shipments. Consolidation fills up the containers more efficiently that reduces the overall carbon footprint. The objective of this paper is to support decisions on selection of appropriate combination of container sizes and shipment consolidation for a manufacturing company. We develop two-steps model which first takes the volumes to be shipped as an input and provide the combination of container sizes required; then …

Temporal Variations Of Water Productivity In Irrigated Corn: An Analysis Of Factors Influencing Yield And Water Use Across Central Nebraska, Tony Carr, Haishun Yang, Chittaranjan Ray 2016 University of Nebraska-Lincoln

Temporal Variations Of Water Productivity In Irrigated Corn: An Analysis Of Factors Influencing Yield And Water Use Across Central Nebraska, Tony Carr, Haishun Yang, Chittaranjan Ray

Nebraska Water Center: Faculty Publications

Water Productivity (WP) of a crop defines the relationship between the economic or physical yield of the crop and its water use. With this concept it is possible to identify disproportionate water use or water-limited yield gaps and thereby support improvements in agricultural water management. However, too often important qualitative and quantitative environmental factors are not part of aWP analysis and therefore neglect the aspect of maintaining a sustainable agricultural system. In this study, we examine both the physical and economic WP in perspective with temporally changing environmental conditions. The physical WP analysis was performed by comparing simulated maximum attainable …

Effects Of Early Exposure To Sign Language On The Biomechanics Of Interpreting, Abigail Donner, Matthew Marshall, Jacqueline Mozrall

Journal of Interpretation

Sign language interpreters are routinely exposed to the high physical and cognitive demands inherent to the profession. Unfortunately, many interpreters suffer from musculoskeletal disorders as a result of this exposure. There are a myriad of factors that can contribute to the development of a musculoskeletal disorder, but many of these are not under the control of the interpreter. However, individual technique is something that affects upper extremity biomechanics and is something that an interpreter can regulate. Research with musicians has demonstrated that early exposure to musical technique can lead to the development of a technique that is more biomechanically efficient …

Engineering Management and Systems Engineering Faculty Research & Creative Works

A city's transportation infrastructure deeply affects its citizens' quality of life-from the freshness of food to the amount of frustration felt while commuting to work. Providing an optimal infrastructure has the possibility of dramatically improving the population's well-being. Since the transportation infrastructure is a system-of-systems (SoS) [1], it may be modelled and optimized for a given set of objectives [2]. In this manner, the city resources can be optimized for multiple objectives such as commute time, overall throughput, and sustainability. This is made possible by using a fuzzy assessor to map the individual objectives into a single overall fitness value …

Exploring Regional And Telecoupled Land Use Change Impacts From Environmental Shocks, Kevin Hill, Liz Wachs, Brady Hardiman, David Yu, Shweta Singh

The Summer Undergraduate Research Fellowship (SURF) Symposium

Natural disasters or environmental shocks have the potential to disrupt local agricultural systems as well as distant agricultural systems through cascading effects. In this work we selected two distinct environmental shocks and traced their cascading effects on land use change. Quantifying cascading effects is a salient issue because climate change forecasts indicate an increase in frequency and intensity of global environmental shocks. This study incorporated the concept of telecoupled systems involving interrelating ecological, economic and political/social components. A telecoupled framework involving cascading effects was implemented using three approaches. The first approach involved using bilateral agricultural trade matrix data to analyze …
