  • A 1974 perspective of art interest among students enrolled in basic college art courses between 1968 and 1970

    Creator:
    Hardin, Priscilla
    Abstract:
    It can be hypothesized that the degree to which students value learning in the visual arts influences the amount of involvement in art oriented activities that will be pursued in later years. This investigation has compared former college students° valuations of the Basic Design course with levels of art interest...

  • The generic knapsack factory : decision rules for sequential knapsack problems with an additional constraint

    Creator:
    Hehnen, Mark Thomas
    Abstract:
    Consider the situation where one is faced with a sequence of knapsack type problems which involves additional constraints on the permissible number of certain types of knapsack fillers to be used over the sequence. This research is concerned with determining good and perhaps optimal solutions which maximize the total value...

  • Optimal policies in continuous Markov decision chains

    Creator:
    Ott, Melvin Leroy
    Abstract:
    For continuous time, finite state and action, Markov decision chains, optimal policies are studied; (i) a procedure for transforming the terminal reward vector is given and it is established that this transformation does not alter optimal policies, (ii) decision chains with absorbing states are studied and the results obtained are...

  • Untangling the complexity of nearshore ecosystems : examining issues of scaling and variability in benthic communities

    Creator:
    Schoch, G. Carl
    Abstract:
    The objective of this research was to improve our understanding of how changes in the environment affect ecological processes. Change detection is often confounded by the large variation found in ecological data due to the difficulty of finding replicates in nature. Intertidal communities were chosen for studies of biophysical interactions...

  • Physical-biological interactions in the Southern Ocean

    Creator:
    Moore, Jefferson Keith
    Abstract:
    Physical-biological interactions in the Southern Ocean were investigated using remote sensing data from several different satellite sensors. Satellite sea surface temperature data were used to study the dynamics of the Antarctic Polar Front (PF). Satellite ocean color data were used to estimate surface chlorophyll concentrations and their relation to various...

  • Studies on the spatial variability of phytoplankton physiology and biomass in the Oregon upwelling system

    Creator:
    Sanders, Rachel B.
    Abstract:
    The Oregon upwelling system is a region of high biomass and primary productivity as well as strong mesoscale variability. In order to examine the interaction of physical forcing and ecosystem dynamics, four 3-week sampling cruises were conducted in the Oregon upwelling system as part of the Northeast Pacific Global Ocean...

  • Physical and chemical factors controlling the distribution of the major phytoplankton classes at the Antarctic Polar Front, 170 °W

    Creator:
    Mengelt, Claudia
    Abstract:
    This study was part of the Antarctic Environment and Southern Ocean Study (AESOPS) program, whose main goal was to investigate the role of the biota in the carbon flux from the atmosphere to the interior of the ocean. We quantified the abundance of the major phytoplankton classes and examined the...

  • Laboratory investigations of the natural fluorescence of marine phytoplankton

    Creator:
    Laney, Samuel R.
    Abstract:
    The influence of nitrate availability and irradiance on phytoplankton natural fluorescence was investigated in laboratory cultures of the marine diatom Thalassiosira weissflogii (Bacillariophyceae). Two cultures of phytoplankton, differing only in the nitrate-limited growth rate, were compared to learn how increases in irradiance influences natural fluorescence. Instrumentation was developed for these...

  • Seconds to hour scale photosynthetic responses in marine microalgae

    Creator:
    Laney, Samuel R.
    Abstract:
    Our view of phytoplankton has historically revolved around their inability to control their location in space. The term phytoplankton itself underscores this particular difference between phytoplankton and their sessile terrestrial counterparts. Yet there are other differences between land plants and the phytoplankton that are perhaps equally important, beyond this sessile-planktonic...

  • Primary production dynamics in the North Pacific subtropical gyre

    Creator:
    Corno, Guido
    Abstract:
    The North Pacific subtropical gyre (NPSG), once considered to be a biological desert due to low primary production (PP) and its associated variability, has been found more productive and variable than previously thought. The environmental conditions controlling this relatively high PP variability are yet to be elucidated, despite important implications...
