Simplified Framework Evaluation Of Large Water Resource Project Impacts, Brian Woodbridge Clowes

Dissertations and Theses

The document most frequently used to support a water resource project's economic feasibility is the commercial benefit-cost analysis, which quantifies tangible and direct project consequences. The objective of this type of analysis is simply to maximize net monetary benefits. This analysis assigns an arbitrary monetary value to ecological and social disruptions, if it does not ignore these effects entirely. An improvement on this method is the social benefit-cost analysis, which assesses sane intangible costs such as air and noise pollution. Unfortunately, even the social analysis usually neglects the sometimes profound effects that a large water resource project has upon quality …

An Empirical Assessment Of The Center-Periphery Hypothesis In International Economic Relations, Fazlollah Bonakdar Shirazi

Dissertations and Theses

Modification Of The Ca²⁺ Release System Of Skeletal Muscle Sarcoplasmic Reticulum Vesicles Via Sulfhydryl Oxidation And Tryptic Proteolysis, Jonathan Lee Trimm

Dissertations and Theses

Isotopic and spectrophotometric assays show that micromolar concentrations of heavy metal ions (particularly Ag⁺ and Hg²⁺) stimulate ATPase activity but inhibit Ca²⁺ uptake in isolated SR vesicles. Both effects are caused by increased Ca²⁺ permeability of the membrane, apparently the result of activation of the Ca²⁺ release system of the vesicles due to heavy metal binding to a critical sulfhydryl group associated with the Ca²⁺ release channels. CU²⁺catalyzed co-oxidation of this sulfhydryl with exogenous cysteine to form a mixed disulfide also results in activation of the Ca²⁺ release system. The rate and extent of Cu²⁺/cysteine-induced release is maximal at physiological …

The Tensile Strength Of Liquid Helium Four, Joel Alan Nissen

Dissertations and Theses

It is well known that most liquids exhibit a tensile strength which is much smaller in magnitude than the tensile strength predicted by homogeneous nucleation theory. This lack of agreement is usually attributed to the difficulty of preparing liquid samples free from foreign gases which act as heterogeneous nucleation sites. Liquid helium occupies a unique place among liquids for tensile strength measurements because all foreign gases are frozen out at liquid helium temperatures. Furthermore, superfluid 4He should fill all crevices on solid surfaces, eliminating the chance of heterogeneous nucleation on helium vapor pockets. Despite the quantum mechanical nature of liquid …

The Socialization Of Cpep Teachers: Implications For Administration, Jim L. Kuhlmann

Dissertations and Theses

The competencies and needs of those entering the teaching profession have become the subject of public debate since the release of A Nation at Risk. Subsequently many comprehensive and comparative reviews have documented the socialization of those entering the teaching profession especially student teachers and first-year teachers. The problems of beginning teachers have produced survival and self-oriented concerns. Internships and induction programs have been developed to ease the socialization of beginning teachers and mediate these concerns. As internships are developed and induction programs implemented, descriptive field studies which examine the processes of beginning teacher socialization are needed. Particularly, studies which …

A Study Of The Capability Of The Computerized Visi-Pitch When Investigating Prosodic Features Of Motherese, Denise Leslie Clemens

Dissertations and Theses

With commercial availability of non-real and real-time spectrum analyzers, the speech-language pathologist has the means to objectively extract and measure pitch taken from speech samples. Though both types of spectrum analyzers provide the clinician with viable methods of measuring fundamental frequency and frequency range values, pitch extraction using real time allows for greater efficiency in acoustic measurements. The Kay Elemetrics Visi-Pitch is one such real-time spectrum analyzer that is less expensive and more accessible than other real time speech science hardware. The purpose of this study was to investigate the capability of a computerized Visi-Pitch to reflect elevation of fundamental …

Patterns In Creativity : An Examination Of Viennese Culture And Politics At The Turn Of The Century, Allen Nolan Hauser

Dissertations and Theses

This examination explores the Viennese cultural milieu at the turn of the century in an effort to show the commonality of backgrounds and interests among those who created the culture during that period. In this the study aims at illustrating the similarities among those artists, intellectuals, and politicians in spite of the fact that their ideas helped lay the basis for the breakdown in integration of twentieth century culture which was illustrated by Carl E. Schorske in his Fin-De-Siecle Vienna: Politics and Culture. All this is in pursuance of the overall issue of the origin of the ideas which have …

Adolescent Shoplifting And Situational Stimuli, James A. Chambers

Dissertations and Theses

Adolescent shoplifting has provoked limited and somewhat controversial perspectives within the sociological and psychological literature. These controversies center around the empirical variables used for analysis. A companion argument focuses on the subjective and objective measurement of these variables. This research explicated variables from the sociological literature to test their relationship, using multiple linear regression, to adolescent shoplifting behavior. These variables and situational stimuli were operationalized in a simultaneous model to demonstrate a proximate occurrence of the attitude-situation-behavior reciprocal. This reciprocal is a learning theory which suggests that direct and vicarious experiences accompanied by rewards and punishment, in one's environment, lead …

Fractional Representation Design Of Dynamic Output Controllers For Multiple Time Scale Systems, Robert Stephen Jaffe

Dissertations and Theses

This dissertation addresses the design of controllers for multi variable finite-dimensional, linear, autonomous dynamical systems with distinct sets of slow and fast dynamics, which thus display multiple time scale behavior. It seeks, specifically, to compose overall controllers from lower-order dynamic output compensators, which are designed separately for slow and fast approximating models of the given plant. Reduction of the dynamic order of the design problem and the avoidance of numerically ill-conditioned interaction between modes of disparate orders of magnitude are among the patent advantages which pertain to such a design. As is well known, the explicit singularly perturbed systems, as …

The Development Of A Social Network Following Geographic Relocation, Joan E. Starker

Dissertations and Theses

The United States is a strikingly mobile nation. Every year almost 20% of its population changes residence and about 45% moves at least once every five years. Economic considerations are a major reason for relocation as persons seek new employment or are transferred by their corporations. Relocation, however, can be a stressful life experience. It removes individuals from daily routines, alters social networks, and may be accompanied by a mixture of sadness, excitement, anger and anxiety. It requires an enormous investment of physical and emotional energy to reestablish order and stability to one's life in a new city. At the …

Martin Pollard, who graciously allowed me to examine original copies of the newspaper and gave me the benefit of his personal historical expertise about both the paper and Br. Colestin. For my research on the newspaper I did not use the original bound copies of the Blatt, which were too sensitive and brittle to …

The Phonology Of Kisi Ideophones, George Tucker Childs

Applied Linguistics Faculty Publications and Presentations

The category of words which I consider in this paper performs a function often neglected in linguistic analyses, namely, the expressive function: the expression of one's own personal feelings towards the message, Besides expressing the personal feelings or attitudes of the Speaker, ideophones serve the poetic function as well. They add an extra dimension of artistry or play. Expressiveness typically occurs only in special types of discourse, such as in Nootka songs, and possesses a systematicity of its own (Sapir 1915 [1949-188]). Because of the special pragmatics of expressive language, it has often been neglected in more restricted analyses. This …
