A framework for integrated design of process and operation is proposed for metal-degreasing process in metal processing. In metal degreasing, a significant amount of cleansing agents is released to the environment, and local risks and global impacts originated in the cleansing agents have been crucial issues. The framework enables the engineers on site to perform rigorous risk assessments by us...

Managers often lament that their employees are risk averse and do not take sufficient risks. While in some instances employees might in fact be too risk averse, we explore situations in which managers may incorrectly judge their employees to be overly risk averse or timid. In two studies, we find evidence of a timidity bias in evaluations--evaluators judge target decision makers to be risk aver...

Conducting a barriers analysis is an important first step when designing proenvironmental behavior change interventions. Yet, detailed information on common barriers to energy conservation campaigns remains unavailable. Using a pair of original surveys, we leverage the theory of planned behavior to report on the most important barriers for fourteen energy conservation behaviors common in univer...

Parametric design is an emerging research issue in the design domain. However, our current understanding of creativity in relation to either a process or product standpoint is limited. This paper presents a formal approach for the description and identification of creativity from both perspectives. The framework combines: (i) protocol analysis for encoding cognitive design activities, providing...

At the invitation of Prof. Robert Bea, of the Deepwater Horizon Study Group (DHSG), the following technical summary of the "Golden Zone" concept (Buller et al, 2005; Nadeau, 2011), its applications in the US Gulf of Mexico basin, implications for drilling safety, and lessons learned particularly over the last 6 months, has been prepared. It is hoped that this Working Paper with further advance ...

Studies have consistently found that safety and security are major public concerns; however, crime is rarely considered as an outcome in public health. The recent shift by planning policy towards promoting compact, 'walkable' communities close to public transport aims to redress many of the problems associated with urban sprawl. However, communities that do not feel safe are less likely to be a...

Much of the production in firms takes place over time. This paper seeks to understand the value of interim performance information on long projects. In particular, the model explores the sorting effects of performance evaluations. Conducting an interim performance evaluation increases efficiency by providing the option to end projects with low early returns. The main result: It is efficient to ...

A disaster is a failure of resilience to an event. Mitigating the risks that a hazard will progress into a destructive event, or increasing the resilience of a society-at-risk, requires careful analysis, planning, and execution. The Disaster Logic Model (DLM) is used to define the value (effects, costs, and outcome(s)), impacts, and benefits of interventions directed at risk reduction. A Risk-R...
