Solar Energy Resource Potential in Alaska
Solar energy applications are receiving attention in Alaska as in
much of the rest of the country. Solar energy possibilities for Alaska
include domestic water heating, hot-water or hot-air collection for
space heating, and the use of passive solar heating in residential or
commercial buildings.
As a first analysis, this study concentrated on applying solar
energy to domestic hot-water heating needs (not space heating) in Alaska,
and an analysis of solar hot-water heating economics was performed using
the F-CHART solar energy simulation computer program. Results indicate
that solar energy cannot compete economically with oil-heated domestic
hot water at any of the five study locations in Alaska, but that it may
be economical in comparison with electrically heated hot water if solar
collector systems can be purchased and installed for 25 per
square foot.This work was made possible by a grant from the Solar Planning
Office, West, 3333 Quebec, Denver, Colorado. It was performed as the
Alaskan response to a western regional solar energy planning grant from
the U. S. Department of Energy.
The authors wish to acknowledge the support and cooperation of the
Alaska State Department of Commerce, Division of Energy and Power Development,
through whose efforts the grant was made available, especially

The GlueX Experiment: Recent Results and Future Plans
The GlueX experiment, located in experimental Hall D of Jefferson Lab, seeks
to map the spectrum of light mesons in search of exotic hybrid mesons, a
predicted class of hadronic states with explicit gluonic degrees of freedom.
GlueX is a photoproduction experiment utilizing a linearly polarized photon
beam at 8-9 GeV and a large acceptance spectrometer. The experiment
has already collected orders of magnitude more data than previous experiments
at similar energies. We show results on asymmetry measurements in the
production of pseudoscalars mesons, which refine our understanding of
production mechanisms in photoproduction at our energies. We also present
results on photoproduction, which provides model constraints on heavy
quark photoproduction and the ability to search for s-channel production of
pentaquark candidate states
Improving the Leadership of P-12 Administrative Teams
Traditional individualistic approaches to leadership and learning have failed to create the systems change and continual improvement school districts need. As a result, school districts have increasingly turned to use administrative teams to solve complex systems issues. Unfortunately, many of these groups fail to become a real team. Facilitating a groups transformation into a team that effectively engages learning is not easy.
The primary goal of this case study is to assist team leaders in improving their leadership of P-12 administrative teams, primarily by gaining the perspectives of team members. These perspectives have been gathered from ten exceptional P-12 administrative team members (five district directors and five principals). This qualitative case study uses their interviews and follow-up focus groups to delve deeper into their initial insights and perspectives on the guiding research question: What are the insights and suggestions of a team of P-12 principals and district directors that could benefit team leaders who are creating teams to collaborate and learn together? The significant findings and implications outline what leaders should do to increase the likelihood of a group becoming a high performing team, and what may hinder leaders from transforming a group into a team. The most critical finding: The leader makes or breaks the team. Fortunately, leaders can learn to be effective, transformational team leaders
Circular 64
Treatment of Alaska-produced food products by ionizing radiation may
benefit the seafood and agricultural industries and the Alaskan consumer. A
feasibility study to evaluate the potential social and economic benefits and
risks as well as the costs of using the process in Alaska on Alaskan products is being coordinated
by the Institute of Northern Engineering. A research and development project to determine
effects on the quality o f Alaskan products could be the next phase in the introduction o f a new
food-preservation technique
