Public Service Employment: The Experience of a Decade
From 1971 to 1982, the federal government attempted to reduce unemployment by subsidizing positions in state and local governments. These efforts were geared toward helping the unemployed gain human capital that could lead to unsubsidized work, while helping governments provide needed services for their citizens. A variety of approaches were tried in practically every area of program design. The authors reveal what worked.https://research.upjohn.org/up_press/1125/thumbnail.jp

Phytosociological analysis of restored and managed grassland habitat within an urban national park
Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives annual mowing, as well as continued manual removal of the larger woody sprouts.
A portion of the GRAMP management area (III) was selected for intensive study of vegetation composition. A grid system was created and vegetation cover was estimated in 127, 1 m × 1 m quadrats. The quadrats were subjected to cluster analysis (CA). Eleven clusters were recognized. These clusters were treated as “plant associations.” The following types were distinguished: (native) little bluestem–dewberry grassland, six-weeks fescue annual grassland, a grass marsh, a rush marsh, a switchgrass dry grassland, and a deer-tongue panicgrass grassland; (exotic) mugwort herbland, oriental bittersweet-Japanese honeysuckle vineland, Kentucky bluegrass-mixed grassland, Japanese knotweed tall herbland, and spotted knapweed-common St. Johnswort herbland. The little bluestem–dewberry association accounted for nearly half of all quadrats; six subclusters were recognized. The plant associations determined by CA were compared with plant lists compiled during traverses of all of the map categories in the six GRAMP Areas (I, II, III, IV, V, VI). A table was created to relate the quantitative data of the plant associations to the appropriate map categories. A nonmetric multidimensional scaling ordination (NMDS) was performed on the quadrat data. Finally, the plant associations were compared with those described in the literature of local vegetation studies. The mowing program has been effective in decreasing woody plant cover and has permitted the invasion of a few taxa into monospecific communities, but attendant disturbance of the substrate is likely to cause an increase in exotic plant taxa. As earlier studies noted, mowing has caused the increase in cover of sod-forming grass, and bare ground has virtually disappeared in the managed area. This has negative implications for the maintenance of those grassland bird species that require open ground for nesting
Hydrographic observations from the US/PRC Cooperative Program in the Western Equatorial Pacific Ocean, cruises 1-4
In support of the Tropical Oceans and Global Atmosphere (TOGA) program, investigators from Woods Hole Oceanographic
Institution (WHOI), NOAA Pacific Marine Envionmental Laboratory and the State Oceanic Administration (SOA) from both
Qingdao (First Institute) and Guangzhou (South China Sea Branch) conducted hydrographic observations aboard the Chinese
Research vessels Xiang Yang Hong 5 and Xiang Yang Hong 14 in the western equatorial Pacific. The objective of this component of
the TOGA program was to document the water mass property distributions of the western equatorial Pacific Ocean and describe the
oceanic velocity field. The four cruises summarized here were conducted during the period November 1985 to June 1988 and are
the first half of an eight cruise repeated survey of the region scheduled to be completed in spring 1990. Conductivity-Temperatue-Depth-Oxygen (CTD/02) stations were collected to a minimum cast depth of 2,500 m or the bottom when shallower. The cruises reoccupied the same stations to provide temporal information. Summarized listings of CTD/O2 data together with selected physical
properties of sea water for these cruises are provided here, as well as a description of the hardware used and an explanation of the
data reduction tehniques employed.Funding was provided by the National Oceanic and Atmospheric Administration
