The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space

2007 ), â Rethinking of Risk Communication: Lessons from the Decision
Abstract Risk communication involves three primary elements: process, content and intent. Much has been written about the first two. Much is known, for example, about the guiding principles that should be considered during the design of a risk communication. Likewise, many studies have been conducted about how best to establish the technical and informational content of a risk communication. Very little attention, by contrast, has been devoted to the intent of risk communication, which is to inform decision making for risk management. While appropriate information upon which to base risk management decisions is important, so to is an understanding of how people instinctively approach decision making under conditions of risk. Work in the decision sciences provides this oftenmissing perspective for many risk communication efforts and is, therefore, the focus of this paper
Decision Support Framework for Developing Regional Energy Strategies
In an effort to reduce âcarbon
pollutionâ as well
as prepare the U.S. for the impacts of climate change, President Obamaâs
2013 Climate Action Plan calls for changes to be made to the nationâs
energy system. In addition to focusing on alternative portfolios of
different fuels and power-generation technologies, researchers and
advisory panels have urged that changes to the nationâs energy
system be based on a decision-making framework that incorporates stakeholders
and accounts for real-world resource, supply, and demand constraints.
To date, research and development on such a framework have proven
elusive. The research reported here describes the development and
test of a potential decision support framework that combines elements
from structured decision-making (SDM) with portfolio analysis, methods
that have been used independently to elicit preferences in complex
decision contexts. This hybrid framework aimed to (1) provide necessary
background information to users regarding the development of coupled
climate-energy strategies; (2) account for usersâ values and
objectives; (3) allow for the construction of bespoke energy portfolios
bounded by real-world supply and demand constraints; and (4) provide
a more rigorous basis for addressing trade-offs. Results show that
this framework was user-friendly, led to significant increases in
usersâ knowledge about energy systems and, importantly, led
to more internally consistent decisions. For these reasons, this framework
may serve as a suitable template for supporting decisions about energy
transitions in the United States and abroad
Consumer-perceived risks and choices about pharmaceuticals in the environment: a cross-sectional study
Background
There is increasing concern that pollution from pharmaceuticals used in human medicine and agriculture can be a threat to the environment. Little is known, however, if people are aware that pharmaceuticals may have a detrimental influence on the environment. The present study examines peopleâs risk perception and choices in regard to environmental risks of pharmaceuticals used in human medicine and for agricultural purposes.
Methods
A representative sample of the U.S. population (N = 640) was surveyed. Respondents completed a hypothetical choice task that involved tradeoffs between human and environmental health. In addition, it was examined how much people would support an environment policy related to drug regulation.
Results
For agricultural pharmaceuticals, respondents reported a high level of satisfaction for a policy requiring farms to limit their use of antibiotics. In the domain of pharmaceuticals used in human medicine, we found that people were willing to consider environmental consequences when choosing a drug, but only when choices were made about treatment options for a rather harmless disease. In contrast, when decisions were made about treatment options for a severe disease, the drugâs effectiveness was the most important criterion.
Conclusions
It can be concluded that the environmental impact of a drug will be hardly considered in decisions about pharmaceuticals for severe diseases like cancer, and this may be due to the fact that these decisions are predominantly affective in nature. However, for less severe health risks, people are willing to balance health and environmental considerations.ISSN:1476-069
