User's guide for atmospheric carbon monoxide transport model
In the winter months of Fairbanks, Alaska, a highly stable air temperature
inversion creates high levels of carbon monoxide (CO) concentrations. As an aid
to understanding this problem, a CO transport computer model has been created
which provides a useful tool when used in conjunction with other measurement and
analytic studies of traffic, meteorology, emissions control, zoning, and parking
management. The model is completely documented and illustrated with several
examples. Named ACOSP (Atmospheric CO Simulation Program), it predicts expected
CO concentrations within a specific geographic area for a defined set of CO
sources. At the present time, the model is programmed to consider automobile
emissions as the major CO source and may include estimates of stationary sources.
The model is coded for computer solution in the FORTRAN programming language and
uses the finite-element method of numerical solution of the basic convective-diffusion
equations. Although it has a potential for real-time analysis and control,
at the present time the model will be most valuable for investigating and understanding
the physical processes which are responsible for high CO levels and for
testing remedial control measures at high speed and low cost
Controlled Environment Agriculture: A Pilot Project
The controlled-environment agricultural (CEA)
project discussed in this report was first conceived for
the Wildwood Air Force Station in Kenai, Alaska, in
1972. The region contained high unemployment and a
U.S. Air Force Station that had just closed. The Kenai
Native Association, Inc. (KNA), was to take possession
of the Air Force Station through land transfers associated
with the Alaska Native Claims Settlement Act,
and this corporation was interested in expanding
business and employment opportunities for local
people. The University of Alaska Agricultural Experiment
Station (AES) contacted KNA to determine if it
had a facility which might be adaptable for use in a
research and development program in controlled-
1
environment agriculture. It was determined that such
a facility was available. Subsequently, AES and KNA
contacted the General Electric Company (GE) in
Syracuse, New York, to determine its interest in such a
project. GE had extensive background in lighting technology
and environmental control systems and the
engineering capability to develop a total system for
CEA production. It was agreed that GE would provide
technological expertise and AES would provide horticultural
and economic expertise for the growing and
marketing of a variety of salad crops. KNA would
manage the project, employ the nontechnical people,
and provide the building.
The Wildwood site was selected because it contained
two buildings which were thought to be well
suited for CEA production. One building would provide
sufficient inside space for a 1/4-acre pilot production
plant, nine small research modules , a laboratory ,
offices, a training area, and space for preparing the
crop for shipping. A second building near the first
contained three diesel generators which were to be
converted to natural gas to provide power for the
production facility.The Controlled Environment Agriculture Project
at Wildwood Village, Kenai, Alaska, spanned a period
of five years. During that time, three agencies: Kenai
Native Association, Inc.; General Electric Company;
and University of Alaska Agricultural Experiment Station
, were responsible for the management, research,
and production activities. Many persons from these
agencies who participated in all phases of the project
are acknowledged for their participation and support.
This report summarizes work began in 1972 and
concluded in 1977 on controlled-environment agriculture
in facilities located at Wildwood Village, Kenai,
Alaska, managed by the Kenai Native Association , Inc.

Reconciling Ethnicity and Nation: Contending Discourses in Fiji's Consitutional Reform
The process of Fijiâs recent constitutional reform highlighted the dilemma of reconciling a principle of indigenous Fijian paramountcy with an imperative to shape a multiethnic nation for which non-Fijian, particularly Indian, contributions have long been crucial. The article addresses this dilemma in a discussion of the dominant themes in public discourse about constitutional change, and the relation of these themes to the values, pressures, and opportunities of three arenas: ethnic, national, and international. Three contrasting paradigms for the nation are identified: a universalist vision grounded in international human rights ideology, an exclusionary Fijian ethnonationalism affirmed most strongly in the army coups of 1987 and their aftermath, and an interethnic accommodation and partnership in which leading Fijian chiefs continue to have a stabilizing and legitimating function. The last model prevailed in the constitutional reform, demonstrating a continuity with trends in the shaping of political culture during colonial and early postcolonial times. The story of the constitutional reform is in part the saga of how the ethnonationalist coup maker who became prime minister, Sitiveni Rabuka, has tried to remake himself as a national leader. In the crucial role he eventually assumed as overseer of reform, he depended on support from chiefs and their councils. The paper concludes, against much of the postcoup literature on Fiji, that over the long term the major significance of the chiefs in the national political arena is not as a privileged âvested interestâ group obstructing a solution to the problem of establishing a viable democratic polity, but as part of this solution
A Look Back At The Veterinary Student
Editors note: This was a wonderful letter to receive because it so nicely commented on the people and situations that produce a publication such as this. It made this staff feel good about not only where the ISU Veterinarian is going, but from whence it came.
Half a century may sound like a long time, but memories of the early days of The Veterinary Student (the original name of the Iowa State University Veterinarian) are as vivid as they are persistent. The staff was proud of this pioneering venture and flattered to be imitated by Student AVMA chapters over the nation

Determining what materials to develop
How do you determine what materials to develop? By using a new model that is so efficient and effective, it practically guarantees the production of relevant high-quality CBE materials at the lowest possible cost. The SCID model was carefully developed to incorporate the critical tasks needed to develop the kinds of CBE curriculum and instructional materials needed to train tomorrowâs work force today. Twenty-three componentsâa few optional but most essentialâare grouped into five phases: Curriculum analysis, Curriculum design, Instructional Development, Training Implementation, and Program Evaluation. This model has been used since 1990 to train over 1000 curriculum specialists, and training and development specialists from schools, colleges, companies, and government agencies, domestically and internationally. SCID is a process that works
