Influence of Water Depth on the Rate of Expansion of Giant Cutgrass Populations and Management Implications
Giant cutgrass (
Zizaniopsis miliacea
(Michx.) Doell. &
Asch.), a tall emergent grass native to the southeastern United
States, was studied in Lake Seminole where it formed
large expanding stands, and Lake Alice where it was confined
to a stable narrow fringe
U.S. Foreign Policy and Its Development
The remarkable group of men who presided over our national defenses when our Republic was very young were wholly cognizant of the relation between armed force and foreign policy. They knew why the infant republic on the overseas periphery of the Western European civilization area had a chance to grow to maturity

Historical Development of U.S. Foreign Policy
If there is any one continuing theme which will run through my remarks, it is that the basic attitudes which Americans bring to perplexing problems of foreign policy has changed remarkably little since the early days of the Republic. The world, however, and especially the United States itself, has changed a good deal, and it is therefore hardly surprising to find that American foreign policy has changed along with it, for if one applies old ideas to new situations, one is likely to get new policies
Report to Governor’s Blue Ribbon Commission on Tax Reform by Economic Consultants
Excerpts from the executive summary:
Two basic points come from our analysis of Kentucky’s tax system: a broader tax base is needed so that revenue can keep pace with future economic growth, and changes are needed to improve Kentucky’s economic competitiveness.
Without fundamental reforms Kentucky could face a $1 billion shortfall by 2020, and could find itself at a competitive disadvantage to neighboring states for business growth, retention, and recruitment.
The options we present below can improve future revenue growth and economic competitiveness—which are evaluated with respect to other important factors, such as fairness and simplicity. The Commission should view these options as alternative routes to a different tax system, but with varying implications for adequacy, elasticity, competitiveness, fairness, and simplicity
Seasonal Sediment Migration and Sediment Dynamics on Sandy Point Beach, San Salvador Island, Bahamas
A study of the dynamics of Sandy Point Beach along the southwestern corner of San Salvador Island over an eighteen-month period, beginning in June, 1990, has revealed that two seasonal phases of sediment transport are operative. Based primarily on analyses of the grain-size parameters of sand samples collected from the beach in June, 1990, a northerly direction of sediment transport was detected. This is herein termed the Spring/Summer phase of transport, and it results from the energy of waves generated by the prevailing easterly trade winds. Continued profiling of the beach in December, 1990, and January, 1992, revealed that a strong southerly transport direction is dominant during the fall/winter months.The energy for this phase of sediment transport comes from northwesterly storms. It appears that during such events, large amounts of sediment can be moved rapidly toward the southern end of the beach
Long-Term, Seasonal, and Event-Driven Sediment Movement on East Beach, San Salvador Island, Bahamas
East Beach is a modern, medium-energy shoreline located on the northeast coast of San Salvador Island, Bahamas. Stake and horizon profiles were made at 9 sites along a 1-km section of the beach in June, 1990, and every six months thereafter through January,1992. These observations appear to confirm that East Beach is a prograding shoreline, building onto the eastern shelf of the island. Seasonally corrected volume calculations indicate that between June, 1990 and January, 1992 approximately 14,000 m3 of new sand per kilometer were added to the East Beach system, with most of the sand likely derived from the nearshore shelf area. Visual evidence for progradation could be seen in the formation of a heavily vegetated berm along the backshore, that by June, 1991 had reached a maximum height of 40 cm before its destruction by the powerful storm that hit San Salvador in late October, 1991. Seasonal topographic measurements and volume calculations indicate a minimum of 8,600 m3/km of sediment moving offshore in response to higher average wave energies in the winter, and returning to build a wide foreshore and pronounced berm during the summer months. The late October storm battered East Beach with waves that entrained meter-sized blocks of coral, cut back the primary dune line by an average of 5.1 m, and washed over approximately 1,500 m3of sediment into the primary dune swale. Storm damage was measurably less severe at northern stations, possibly because of sheltering by Northeast Point and Man Head Cay, or by baffling action of the dense patch reefs offshore, or both
