The problem of scheduling jobs to minimize total weighted tardiness in flowshops,
with the possibility of evolving into hybrid flowshops in the future, is investigated in
this paper. As this research is guided by a real problem in industry, the flowshop
considered has considerable flexibility, which stimulated the development of...
This talk will introduce this special session on coastal and marine spatial planning (MSP). An overview of how MSP is interpreted and implemented in the United States at different geographic scales will be discussed. An emphasis on data and research needs will be given as well as context for the...

My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...
Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...
The use of terbacil for weed control was adapted by a high percentage
of Oregon peppermint growers soon after its introduction in
1967. To help clarify some of the implications of terbacil usage,
three studies were undertaken to collect information concerning (a)
the movement and build-up of terbacil in various...
The objective of this study was to identify visual or easily
measured morphological characters associated with seed yield or its
components in a spaced-plant nursery of tall fescue (Festuca arundinacea
Schreb.). In 1977, 26 plant characteristics were observed on 210 plants
from seven different geographic regions of origin. Each origin...
The Asian isopod Ianiropsis serricaudis is now well established in fouling communities, often associated with introduced ascidians, throughout the Northern Hemisphere but has gone largely unnoticed because of its diminutive size (typically less than 3 mm in length) and the difficulties of identifying small peracarid crustaceans. Known locations include the...
Appearing in this issue of the Journal of Physical Oceanography are three papers that present new observations of a distinct, narrow band, and diurnally varying signal in temperature records obtained in the low Richardson number shear flow above the core of the equatorial undercurrent. Moored data suggest that the intrinsic...

"The success of Mysis introduced in Kootenay Lake, British Columbia, prompted their introduction in many kokanee lakes in the Western states. Oregon introduced Mysis into eleven waters during the period 1965-67. Several states have conducted intensive studies to evaluate Mysis introductions. Many studies have concluded Mysis have had a negative...
Here we present a phylogeny of beetles (Insecta: Coleoptera) based on DNA sequence data from eight nuclear genes, including six single-copy nuclear protein-coding genes, for 367 species representing 172 of 183 extant families. Our results refine existing knowledge of relationships among major groups of beetles. Strepsiptera was confirmed as sister...
