Portrait Of The Scientific Journals In Germany: 1930-1936, Paul Eugene Gesling Jr.

Institute for the Humanities Theses

The focus of this .study is to note and measure any discernible changes within the character of scientific publications in Germany after the elevation of the National Socialists to power. To detect any such changes, a classification scheme was established to categorize formal papers appearing in six journals between 1930-1936. The results are subject to variance as the journals examined did not fare identically. Certain journals declined in output while others prospered. Suggestion~ of ideological tampering remain largely absent. Indeed, the wide latitude of interests expressed by these papers suggest a preference on the part of German scientists and editors …

Lineament Analysis And Tectonic Interpretation For The Central Tharsis Region, Mars, Robert C. Anderson

OES Theses and Dissertations

Lineament studies conducted for the Central Tharsis Region of Mars (JOON and JOOS latitude; 450w to 157.50W longitude) indicate two major events controlled the formation of the Tharsis Dome: 1) a pre-Tharsis fracture system consisting of North-West (3150) trending fractures; and 2) a Tharsian fracture system containing North-South (355°) and East-West (275°) trending fractures. The North-West (3150) trending fractures represent a crustal weakness zone which controlled the early formation of the Tharsis Dome. Analytical studies suggest four centers of uplift: 1) 6°N, 124°W; 2) 0.5°N, 114°W; 3) 5°S, 105°W; and 4) 7°S, 104°W. Each of these uplifting centers is associated …

Comparison Of An Improved Plankton Sampler To The Standard Conical Plankton Net, Ronald S. Schmidt

OES Theses and Dissertations

A comparison of field and tank tests between the standard conical plankton net and an improved version of a plankton sampler is presented. The improved sampler was shown to filter larger quantities of water than the standard net without having the filtration efficiency reduced below 85%. The improved sampler was also shown to capture an increased number of plankton per volume sampled, as a result of eliminating increased avoidance activity by zooplankton. It was not shown that. the improved sampler capture either larger maximum sizes of zooplankton or additional species.

Conodont Biostratigraphy Of The Cambrian-Ordovician Boundary Interval In The Northern Shenandoah Valley Of Virginia, U.S.A., Randall C. Orndorff

OES Theses and Dissertations

Conodonts collected from two measured sections in the northern Shenandoah Valley of Virginia indicate that locally the Cambrian-Ordovician boundary is within the upper part of the Conococheague Formation and that the Conococheague-Stonehenge formational contact as defined in this study, is diachronous in relation to the boundary. Using the generally accepted definition of the CambrianOrdovician boundary as at the base of the trilobite Missisguoia Zone or within the conodont Hirsutodontus hirsutus Subzone of the Cordylodus proavus Zone, it is found here that the boundary is 230 ft (70 m) below the formational contact at the Narrow Passage Creek section. Several North …

An algorithmic procedure is developed here for BTS pass networks which is very efficient in terms of both execution time and memory space. Based on these networks, the necessary and sufficient conditions are derived for the design of multiple-output pass networks. …

Depositional Model For The Auriferous Gravels In The Payan Mining District Department Of Narino, Columbia, South America, Jim R. Garrett

OES Theses and Dissertations

Unlike placer deposits in arid and semi-arid environments where gold concentration is closely tied to the position of the bedrock, Payan placer deposits have no association with bedrock. Gold concentration values show highest gold concentrations occur at the contact of a coarse sand unit and its underlying gravel unit. Comparisons of the size and shape distributions of gold grain populations with their associated black sand populations indicate the gold and black sand were not deposited in hydraulic equilibrium. The mean size of each gold population is consistently coarser than the mean size of its associated black sand population despite the …

Social Support Networks: The Effects Of Sex And Personality Variables On Utilization Of Resources, S. Dee Treschuk

Psychology Theses & Dissertations

The purpose of the study was to evaluate the effects of sex and various personality characteristics on the utilization of social support resources for four types of problems (day to day problems, "most serious" problem, emotional and material problems). An interview format was used in order to assess actual events in peoples' lives. Chi-square tests were performed to determine significant differences. Gender differences were found in the use of specific network members for day to day problems. As predicted, females utilized the family more than males; and males named "no one" more than females. For emotional problems, females utilized "love" …

Attributions Of Martial Conflict Among College Students, Gary Franklin Sigler

Psychology Theses & Dissertations

A study of single college student attitudes toward conflict was conducted to determine the attributions (internal versus external) they make regarding marital conflict scenarios (of mild to moderate to extreme severity). Between group differences of persons from divorced versus non-divorced homes were predicted as I well as sex differences with men making more external and females making more internal attributions. As expected, female actors did score higher than male actors on internal attribution. And females from both groups did rate the scenarios as more serious than males from both groups, as indicated by their higher mean rating of seriousness. However, …

Small Farmers' Cooperatives In Brazil, 1964-1984 Reasons For Success Or Failure, Henry H. Gerber

Graduate Program in International Studies Theses & Dissertations

This study is concerned with cooperative business enterprises of small farmers. The topic has been chosen because peasants' association in supply and marketing cooperatives is considered an essential element in rural development. The author's field experience leads him to agree in principle with this assumption. But, as exemplified by Brazil, a variety of factors (ecological, sociohistorical, legal, economic and so forth) may hinder or help the inception and survival of cooperatives.

Thus, if a government aims at integrating the small producer into the national economy as supplier and consumer (as in Brazil), measures to implement t~is policy must not be …

Both high temperature and low temperature properties of GdIG have been studied. The magnetization is along (111) direction over this temperature range. The internal magnetic fields at Fe⁵⁷ sites in GdIG gave two values for the octahedral(a), site which differ by 4-6 KOe and one value for the tetrahedral (d), site at each temperature. Measurements of the total isomer shift in the spectra show that the shift of the center of the spectra consists …

Minimal Norm Constrained Interpolation, Larry Dean Irvine

Mathematics & Statistics Theses & Dissertations

In computational fluid dynamics and in CAD/CAM a physical boundary, usually known only discreetly (say, from a set of measurements), must often be approximated. An acceptable approximation must, of course, preserve the salient features of the data (convexity, concavity, etc.) In this dissertation we compute a smooth interpolant which is locally convex where the data are locally convex and is locally concave where the data are locally concave.

Such an interpolant is found by posing and solving a minimization problem. The solution is a piecewise cubic polynomial. We actually solve this problem indirectly by using the Peano kernel theorem to …

Controlling The Big Stick: The United States Navy And The Cuban Intervention Of September 1906, Christopher A. Abel

Graduate Program in International Studies Theses & Dissertations

A case study method is used to examine the role played by the United States Navy in bringing about the Second Cuban Intervention of 1906-1909. The 1906 American navy had a distinct lack of centralized direction during the September crisis in Cuba. As a consequence, initiative in the crisis passed to the several naval officers representing the United States in Cuba at the time. These officers acted in consonance with the navy's own institutional agendas and contrary to the objectives of the Theodore Roosevelt administration. In so doing these officers were supported and even rewarded for their actions by the …

Curtain Of Silence Japanese In Soviet Custody, 1945-1956, William F. Nimmo

Graduate Program in International Studies Theses & Dissertations

The Soviet Union attacked- and defeated Japanese forces in Northeast Asia in the final days of the Second World War, and 2,100,000 Japanese soldiers and civilians suddenly fell into the hands of the Red Army. This thesis examines the experiences of Japanese in Soviet custody, efforts to obtain their release, and their eventual return to Japan. Repatriation of civilians from Soviet-controlled areas was slow, and military personnel were taken to the USSR for use as forced labor for several years. The Soviets conducted an intensive Marxist-Leninist indoctrination program for prisoners of war, and a professed acceptance of communism was a …
