The Economic Importance of the Bristol Bay Salmon Industry
By any measure, the Bristol Bay sockeye salmon fishery is very large and valuable. It is the world’s most
valuable wild salmon fishery, and typically supplies almost half of the world’s wild sockeye salmon. In
2010, harvesting, processing, and retailing Bristol Bay salmon and the multiplier effects of these activities
created 165 million in direct
harvest value alone. That represented 31% of the total Alaska salmon harvest value, and was greater
than the total value of fish harvests in 41 states. Salmon processing in Bristol Bay increased the value by
390 million. The total value of Bristol
Bay salmon product exports in 2010 was about 500 million in income. For every dollar of direct output
value created in Bristol Bay fishing and processing, more than two additional dollars of output value are
created in other industries, as payments from the Bristol Bay fishery ripple through the economy. These
payments create almost three jobs for every direct job in Bristol Bay fishing and processing.
United States domestic consumption of Bristol Bay frozen sockeye salmon products has been growing
over time as a result of sustained and effective marketing by the industry, new product development and
other factors. This growth is likely to continue over time, which will result in even greater output value
figures for the industry’s economic impacts across the U.S.
The economic importance of the Bristol Bay salmon industry extends far beyond Alaska, particularly to
the West Coast states of Washington, Oregon and California.Bristol Bay Regional Seafood Development Associatio
UA Research Summary No. 15
Utterly worthless. That’s how a congressman from Missouri
described Alaska in 1867, when the U.S. bought it from Russia. A
lot of Americans agreed. For almost 100 years, hardly anyone—
except some Alaskans—wanted Alaska to become a state.
But Alaska did finally become a state, in 1959. Today, after
142 years as a U.S. possession and 50 years as a state, Alaska has
produced resources worth (in today’s dollars) around 7.2 million for Alaska, equal to about $106 million
now. For perspective, that’s roughly what the state government
collected in royalties from oil produced on state-owned land in just
the month of March 2009.
To help mark 50 years of statehood, this publication first takes
a broad look at what’s changed in Alaska since 1959. That’s on
this page and the back page. We’ve also put together a timeline
of political and economic events in Alaska from 1867 to the present.
That’s on the inside pages. There’s an interactive version of the
timeline—with photos, figures, and more—on ISER’s Web site:

Representation to the accident and emergency department within 1-year of a fractured neck of femur
Background:
The fractured neck of femur (NOF) is a leading cause of morbidity and mortality. The mortality attendant upon such fractures is 10% at 1 month and 30% at one year with a cost to the NHS of £1.4 billion annually. This retrospective study sought to examine rates and prevailing trends in representation to A&E in the year following a NOF fracture in an attempt to identify the leading causes behind the morbidity and mortality associated with this fracture.
Methods:
1108 patients who suffered a fractured NOF between 1 January 2002 and 31 December 2007 were identified from a University Hospital A&E database. This database was then used to identify those patients who represented within 1-year following the initial fracture. The presenting complaint, provisional diagnosis and the outcome of this presentation were identified at this time.
Results:
234 patients (21%) returned to A&E on 368 occasions in the year following a hip fracture. 77% (284/368) of these presentations necessitated admission. Falls, infection and fracture were the leading causes of representation. Falls accounted for 20% (57/284) of admissions; 20.7% of patients were admitted because of a fracture, while 56.6% of admissions were for medical ailments of which infection was the chief precipitant (28% (45/161)).
Discussion:
The causes for representation are varied and multifactorial. The results of this study suggest that some of those events or ailments necessitating readmission may be obviated and potentially reduced by interventions that can be instituted during the primary admission and continued following discharge
Additional Ultracool White Dwarfs Found in the Sloan Digital Sky Survey
We identify seven new ultracool white dwarfs discovered in the Sloan Digital
Sky Survey (SDSS). The SDSS photometry, spectra, and proper motions are
presented, and additional BVRI data are given for these and other previously
discovered ultracool white dwarfs. The observed colors span a remarkably wide
range, qualitatively similar to colors predicted by models for very cool white
dwarfs. One of the new stars (SDSS J1251+44) exhibits strong collision-induced
absorption (CIA) in its spectra, while the spectra and colors of the other six
are consistent with mild CIA. Another of the new discoveries (SDSS J2239+00A)
is part of a binary system -- its companion is also a cool white dwarf, and
other data indicate that the companion exhibits an infrared flux deficiency,
making this the first binary system composed of two CIA white dwarfs. A third
discovery (SDSS J0310-00) has weak Balmer emission lines. The proper motions of
all seven stars are consistent with membership in the disk or thick disk.Comment: Accepted for Astrophysical Journal. 16 pages (includes 3 figures
Accretion of gas by globular cluster stars
Some recent observations of the abundances of s-process, r-process, and alpha
elements in metal-poor stars have led to a new scenario for their formation.
According to this scenario, these stars were born in a globular cluster and
accreted the s-process enriched gas expelled by cluster stars of higher-mass,
thereby modifying their surface abundances. Later on, these polluted stars
evaporated from the globular cluster to constitute an important fraction of the
current halo population. In addition, there are now many direct observations of
abundance anomalies not only in globular cluster giant stars but also in
subgiant and main-sequence stars. Accretion provides again a plausible
explanation for (at least some of) these peculiarities. Here we investigate
further the efficiency of the accretion scenario. We find that in concentrated
clusters with large escape velocities, accretion is very efficient and can
indeed lead to major modifications of the stellar surface abundances.Comment: 11 pages; accepted for publication in Astronomy and Astrophysic
