What do government and non-profit stakeholders want to<br />

know about nuclear fuel cycle? A semantic network<br />

analysis approach<br />

Effective risk analysis is critical to improving policy decisions<br />

on complex technologies with a potential <strong>for</strong> catastrophic<br />

consequences. To accurately assess technological risks, it<br />

becomes increasingly important <strong>for</strong> policymakers to incorporate<br />

stakeholder beliefs into the policymaking process. Current<br />

debates on the merits and drawbacks of different nuclear fuel<br />

cycle scenarios in the U.S. and abroad present a challenge to<br />

integrate various concerns of stakeholders with distinct<br />

interests. In this study, we adopted a semantic web analysis<br />

approach to analyze the different sets of beliefs held by<br />

government and non-profit stakeholders about the risks<br />

associated with different aspects of nuclear fuel cycle. In<br />

particular, we conducted in-depth cognitive interviews with six<br />

stakeholders working <strong>for</strong> federal government and six working<br />

<strong>for</strong> non-profit organizations. Participants were asked to freely<br />

talk about the key issues related to nuclear fuel cycle (e.g.,<br />

economics, safety, resources recycle, and non-proliferation). An<br />

artificial neutral network program CATPAC II was used to<br />

analyze the 42 pages transcripts of the twelve one-hour-long<br />

interviews. Results showed that the major concerns of<br />

government stakeholders significantly differ from those of<br />

non-profit stakeholders. While government stakeholders had<br />

salient concerns about the security of transporting nuclear<br />

materials and the implication of nuclear fuel cycle at the state<br />

level, non-profit stakeholders did not assign priority to these<br />

issues. Moreover, although both groups highlighted the<br />

importance of the back-end of nuclear fuel cycle, government<br />

stakeholders focused on the feasibility of recycling nuclear<br />

material, whereas non-profit stakeholders emphasized the<br />

challenges presented by reprocessing. These differences are<br />

illuminated through the use of a hierarchical cluster analysis of<br />

47 unique concepts <strong>for</strong> each group of stakeholders and a visual<br />

representation of the associated mental concepts. Implications<br />

<strong>for</strong> risk analysis and policymaking related to the nuclear fuel<br />

cycle are discussed.<br />

Ambient air pollution and Attention Deficit Hyperactivity<br />

Disorder (ADHD) among children<br />

Attention Deficit Hyperactivity Disorder (ADHD) is the most<br />

commonly diagnosed neurobehavioral disorder of childhood.<br />

Animal studies suggest that traffic-related air pollution may<br />

have adverse neurologic effects, but studies of neurobehavioral<br />

effects in children are still in need. The purpose of this study is<br />

to assess the potential adverse health effects of air pollution<br />

during maternal pregnancy related to childhood ADHD. There<br />

are two databases used in this study: 1) Longitudinal Health<br />

Insurance Database 2005 (LHID2005) and 2) Environmental<br />

Protection Agency (EPA) air monitoring database. Geographic<br />

In<strong>for</strong>mation Systems (GIS) will be used in estimating air<br />

pollution exposure. Furthermore, Cox proportional hazard<br />

regression models will be used in adjusting sex, geographic<br />

area, urbanization level, household Environmental Tobacco<br />

Smoking (ETS) exposure and lead concentrations in air. All<br />

statistical analyses will be per<strong>for</strong>med with the SAS version 9.2<br />

(SAS Institute, Cary, NC, USA). A p-value of less than 0.05 is<br />

set to declare statistical significance. The results showed that<br />

air pollution could be related to childhood ADHD, especially<br />

traffic-related air pollution. Air-pollutant trimester-specific<br />

effect was found. Further research is suggested.<br />

The Role of Dietary Zinc in Cadmium Nephrotoxicity<br />

Background: Animal studies have shown that cadmium (Cd) and<br />

zinc (Zn) are associated with increased and decreased renal<br />

risk, respectively. Goal: To examine the joint effect of Cd<br />

exposure and Zn intake on renal risk. Methods: The data were<br />

obtained from 5,205 adults aged 50 years and older from the<br />

Third National Health and Nutrition Examination Survey<br />

(NHANES III, 1988-94). Results: Logged urinary Cd is positively<br />

associated with albuminuria (odds ratio=1.29; p=0.01). Despite<br />

an apparent protective effect of Zn intake, the finding is not<br />

significant. However when considered jointly with Cd, there<br />

was a significant inverse association between albuminuria and<br />

the Zn-to-urinary Cd ratio (p
