An Experimental Investigation Of The Effects Of Sex And Status On Proxemic Behavior In Dyadic Interviews, Nanelle Davis Russ Jan 1976

An Experimental Investigation Of The Effects Of Sex And Status On Proxemic Behavior In Dyadic Interviews, Nanelle Davis Russ

Retrospective Theses and Dissertations

Man's perception of his personal space can be compared to a basic concept in the study of animal behavior, territoriality, defined by Hall as "behavior by which an organism characteristically lays claim to an area and defends it against members of its own species" (1966, p. 7). Territoriality was first described in 1920 by the English ornithologist H. E. Howard. He recognized events that had been noted by naturalists as far back as the seventeenth century as manifestations of territoriality (Hall, 1966). --From "Chapter 1 Introduction and Rationale."

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller Jan 1976

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller

Retrospective Theses and Dissertations

The mass loadings of pollutants common in surface waters result from the discharges of many different sources. In the last few years it has been noted that nonpoint sources contribute more pollutants than point sources. This is because in many cases the point source discharges have been, by law, reduced drastically. In the State of Florida many water quality parameters were examined to estimate the mass loadings in streams related to, drainage area, average flow, land use, soil type and management practices. A total of sixteen streams were examined. The information was first calculated for mass loadings as a function …

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin Jan 1976

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin

Retrospective Theses and Dissertations

In this paper, two methods for the design of active analog feedback bandpass filter pairs are examined. A third method is presented that does not use extra amplifiers for summation nor multicoupling. This third method uses identical bandpass amplifies and employs resistor summing to provide multicoupling. The name of this configuration is the "Dual Amplifier Bandpass Filter Employing Resistor Summing" (DABFERS). This configuration is economically attractive, has low sensitivity and better phase lag characteristics. In addition, third order prototypes are examined and a solution method for higher order prototypes is suggested.
