The Effects Of Public Commitment And Group Feedback Of Curbside Recycling, Iser Guillermo Deleón

Masters Theses

Several methods for increasing recycling have been presented in the psychology literature. However, many rely on incentive systems that require individual response monitoring for differential delivery of consequences, thus rendering them prohibitively expensive on a community-wide scale. This study examined the effects of three community interventions which may circumvent this limitation: public commitment, group feedback, and a combination of both. The Commitment Only intervention produced no substantial increase in recycling when superimposed upon a curbside recycling baseline. The Feedback Only intervention and the Combined Intervention produced increases of 25.47% and 40.00%, respectively. A no-intervention Control Group decreased in amount recycled …

Assassination In Modern America: Political Participation Through A Gun Barrel?, Richard Grossenbacher

Masters Theses

Assassination has been a constant companion of the world's societies from the beginning of recorded history. Only relatively recently have social scientists begun empirical study of these acts in an effort to reveal any commonalties and possible predictive traits. Investigation of the assassination phenomenon assumed a special urgency in America as violence seemed to escalate in the 1960s, which resulted in some notable research.

The present research collected data of presidential and non-presidential assassinations and attempts that occurred from 1969 through 1992 and compared the findings with the results of earlier studies.

The data indicate that presidential assaults increased in …

A Study Of Aquifer Sensitivity And Vulnerability In Kalamazoo County, Michigan Based On Hydrogeologic And Agricultural Factors, Steven Douglas Chidester

Masters Theses

Groundwater in Kalamazoo County, Michigan has been impacted by human activities. This study presents a statistical method for predicting aquifer sensitivity/vulnerability within a glacio-hydrogeologic system.

Computerized data including 3620 water well records with partial chemical analyses, soil surveys, land use maps, and hydrogeologic reports were used to quantify aquifer parameters, nitrate-N contaminant concentrations, soil factors, and agricultural practices. Statistical analyses included simple t-tests , correlation, ANOV A, and multiple regression analyses.

The results indicate that there are statistically significant relationships between nitrate-N concentrations and depth of well submergence, well depth, clay thickness, partial clay thickness, land use, and soil slope. …

Separation Of Copper And Iron In Natural Waters By Solid-Phase Extraction, Charles Bui

Masters Theses

A separation scheme has been developed by utilizing Solid-Phase Extraction cartridges in order to isolate and characterize the charge of metals and their complexes in natural waters. These species can be analyzed by Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma (ICP), and Ultraviolet-Visible Spectrophotometry (UVVIS).

This separation scheme would permit the determination of the concentration of metals, as well as providing information about the forms in which the metals exist, e.g., charge of metallic complexes.

Synthetic metal complexes were prepared in the laboratory in order to study the separation scheme as well as trying to understand the binding stability of …

A Literature-Based Approach To Reading, Cheryl L. Lester

Using authentic literature, students were taught reading content, prioritized strategies, and necessary reading skills. Progress was assessed using theme tests, periodic reading surveys, skills surveys, observation checklists and forms, student portfolios, and standardized tests.; The results of this study indicated that a primarily literature-based approach inspired and motivated children to become successful readers and writers. The literature produced, emphasized, and enforced positive learning experiences. The assessments used demonstrated that the class became stronger and more enthusiastic …

Size Imperfections In One-Dimensional Periodic Optical Arrays, Yan Zhong

Masters Theses

The concepts of band theory for electrons can also be employed to describe the behavior of electromagnetic waves propagating in periodic dielectric structures. These periodic structures can produce photonic band gaps in which the propagation of electromagnetic waves is strictly prohibited. The introduction of impurities in such system gives rise to donor and acceptor gap modes in electron system and to energy gap modes in photonic system.

In my thesis, the impurity modes in one-dimensional, periodic, dielectric system will be studied. These modes are introduced in the 1-d dielectric structure by altering the thickness of one slab in an otherwise …

Contracts In Conflict: Perestroika And The Decline Of Soviet Legitimacy, Karl Glenn Hokenmaier

Masters Theses

Gorbachev's perception of the Soviet Union's socio-economic crisis and his subsequent actions to correct the economy and reform the political system were linked with attempts to renegotiate the social contract between the state and the Soviet people. However, reformulation of the social contract was incompatible with the conditions of a second arrangement between the leadership and the nomenklatura--the Soviet ruling class. The failure of Gorbachev's reforms and the decline of Soviet legitimacy were linked to the irreconcilability of the nomenklatura's "political contract" and the social contract.

The construct of the social contract was utilized to represent the Soviet state-society relationship …

Attitudes Of Occupational Therapy Students Toward The Mentally Disabled, Patricia Mccarthy

Masters Theses

Thirty-nine undergraduate occupational therapy and fifty-seven entry-level graduate occupational therapy students from eight randomly selected academic programs were surveyed using the Opinions About Mental Illness Scales ([OMI], Cohen and Struening, 1959) and the Mental Health Information Questionnaire ([MHIQ], Nunnally, 1961). Results revealed that both student groups’ knowledge toward the mentally disabled was more similar to the general public’s knowledge. Using a one-tailed t-test to compare the MHIQ factors revealed there was no statistically significant difference between the occupational therapy student groups.

Both student groups’ OMI factor scores were similar to an expert group for Factors A B, and D; however, …

Choosing And Using Children's Literature: The Rationales And Instructional Designs Of Preservice Teachers, Nancy J. Gooden

Masters Theses

This study examined the extent to which preservice teachers were aware of gender related issues in their selection and use of children's literature. The review of research provided background information on the subject of gender equity in children's literature and explored the effects of stereotyped attitudes on students' academic performance, self-esteem, and career choices. The application project used three instruments of study: a gender attitude survey, an analysis of preservice teachers' rationales for literature selection, and an examination of preservice teachers' instructional designs. The results of this study indicated that preservice teachers may benefit from additional exposure to gender issues …

Offense Perceived, Appropriate Actions And Possible Solutions: A Research Of Censorship, Sharon K. Van Poolen

Lyrics containing vulgar or sexual language or derogatory statements about religion received higher offensive ratings. Actions deemed acceptable in response to offensive lyrics include picketing and boycotting. Prevalent themes identified in the lyrics are antagonism toward religion, sexism and unhealthy sexual relations. Groups cited most frequently as potentially harmed by lyrics are children 5-12, adolescents and women. Respondents were questioned about participation in certain activities and what alternatives to direct censorship are acceptable. Most would prefer to be involved indirectly, for example, …

Laboratory Studies Of Filter Pack Grain-Size Distributions And Hydrophobic Treatments To Enhance The Recovery Of Free-Phase Floating Hydrocarbons, Hugh Garret Heuvelhorst

Masters Theses

Experiments were conducted in laboratory sand tanks to evaluate filter pack design criteria in an effort to improve free-product hydrocarbon recovery from sand aquifers. Filter sands were prepared and installed in the test tanks to examine the relative efficiency of two different grain sizes and two different grain-size distributions to imbibe kerosene from the formation sand and release it to their respective wells. Treatments of different chemical products were applied to other filter sands to create a hydrophobic coating on the grains. The hydrophobic coatings were tested on filter sands of different grain sizes and grain-size distributions and compared to …

Nonlinear Dynamic Finite Element Simulation Of Hydroelastic Mounts For Light Weight Vehicles, Talla Jayapal Reddy

Masters Theses

Modern light weight vehicles generate large noise levels, that may need bulky classical rubber mounts to suppress. Hydroelastic mounts can significantly reduce the vibration level of current production automobiles without weight penalty. However, the highly nonlinear behavior of hydroelastic mounts has not been established yet and its use is, therefore, limited to trial and error design methods.

This study discusses the implementation of nonlinear finite element simulation of hydroelastic mounts using the ANSYS finite element code. Fluid elements are limited to linear analysis and therefore are incompatible with the nonlinear hyperelastic elements. A method is proposed to simulate the fluid …

Enhanced Retroreflection Of Light From Rough Metal Surfaces, Sivakumar Natarajan

Masters Theses

The optical constants n and k measured by Johnson and Christy (1972) for the noble metals (gold, silver and copper) are used to analyze the relationship between the surface characteristics and the peak height and half-width of the backscattering peak which is observed in the angular distribution of the intensity of diffusely reflected light at a vacuum-metal interface in a direction antiparallel to the original incident beam. Surfaces with surface roughness of heights less than 200 A to 300 A will be considered and a recently developed perturbation treatment will be used in these studies.

The backscattering of light from …

A Comparison Of The Hutchings’ Low-Stress, Factor Analysis, Hand-Held Calculator, And Conventional Addition Algorithms For Speed, Accuracy, And Preference With Regular Education Students, John C. Hampel

Masters Theses

Three repeated measures experiments were conducted to determine the efficiency with which medium and low math-achieving, fourth- and fifth-grade students computed two sizes of addition problems using each of four different algorithms. The experimenter selected the conventional algorithm and the hand-held calculator because they are currently in popular use. The experimenter selected the Hutchings' low-stress and factor analysis algorithms because of their demonstrated performance enhancing characteristics and unique design features. The three written algorithms represented a design continuum that facilitated a powerful deductive analysis.

In all conditions the Hutchings' low-stress algorithm produced incrementally superior performance consistent with its unique features. …

Impurity Modes In Photonic Band Structures, Yi-Fen Chang

Masters Theses

In this thesis I study a theoretical model of one-dimensional dielectric array (a layered system of dielectric slabs) which forms a periodic dielectric system in which band gaps are opened in the frequency spectrum. Specifically, we study such a one-dimensional array with linear impurities introduced in the periodic dielectric system. In these impurity structures narrow resonant modes are found in the band gaps as impurity modes and these impurity modes change with the dielectric constant. This impurity problem is similar to the donor and acceptor state problem in electronic semiconductors. The calculations presented in this thesis are based on numerically …

Improved Filter-Pack Design For Hydrocarbon Recovery Wells In Unconsolidated Aquifers, Thomas R. Barrett

Masters Theses

Laboratory sand tank experiments and two field studies were conducted to determine filter-pack designs that would increase the hydrocarbon flow rate into hydrocarbon recovery wells. Previous laboratory experiments have shown that using filter-packs of Teflon chips or sands treated with a water repellent spray will increase the rate of hydrocarbon recovery into wells in laboratory bail down test experiments.

The results of the laboratory investigations suggest that using a hydrophobic filter-pack with a median grain-size of 2.5-3.5 greater than that of the aquifer will provide the greatest rate of hydrocarbon recovery.

In two field studies, wells constructed with a hydrophobic …

Multicultural Literature: The Need For Inclusion, Barbara Gripton

Masters Theses

Since Muskegon Public Schools serves a multicultural population, and since the canon of the textbooks used in the secondary language arts classes reflects neither this diverse population nor the current publications of the diverse cultures of the society, this study, in the form of a survey will show the need for the district to include literature contributed by ethnic minority writers from the American literature scene. The study shows the increasing need for such inclusion as well as offering rationale for doing so.; Finally, this paper will propose a three year pilot class, minority literature, similar to the minority history …

Raiders Of The Lost Ark And The Hollywood Tradition: Nostalgia, Parody, And Postmodernism, Michael F. Deters

Masters Theses

The film Raiders of the Lost Ark was released in 1981 to immediate success. Using a noticeably retrospective style, Raiders appealed to the public's desire to experience once again the same kind of viewing pleasure that Hollywood offered in the classical period. Accordingly, the film's nostalgic recreation of classical Hollywood entails a reliance on type characters, tough dialogue, and stock situations--with an overarching emphasis on maintaining a breakneck pace in its action. The appeal for the viewer, then, involves the satisfaction of a need to return to a superficially "simpler" time when the movies themselves were "simpler"--as they fulfilled the …

Inhibition Of Total Gas And Methane Production In Anaerobic Digestion By Various Toxicants, Steven H. Malehorn

Masters Theses

Heavy metal inhibition of anaerobic digestion of municipal sewage sludge has been investigated over the past 50 years. Many assays began with steady-state conditions and observed the rate at which total gas or methane production decreased due to toxicant inhibition. These methods required considerable time and labor. Modified Warburg respirometers and serum bottle assays reduced much of the effort, but each method has limitations in terms of complexity, cost, and accuracy.

This series of experiments had two objectives: 1) develop a quick, inexpensive, and easy method to measure methanogenic activity in anaerobic digesters, and 2) determine median inhibitory concentrations (IC …

Economic Institutions And Economic Growth In South Africa, Lumkile Mondi

Masters Theses

The collapse of rapid growth in industrialized countries in the mid-1970s has suggested to scholars that Keynesian economic management is not the ultimate way to run a viable capitalist system. What has emerged from the crisis is the recognition that different capitalist countries have for long had distinctive patterns of development and alternative patterns of economic management.

One such form of economic management is neo-corporatism. The pillars of "neo-corporatism" are found in the tri-partite alliance between centralized trade unions, centralized employers’ organizations, and the state. These institutions coordinate the levels of investment, wage, and employment in the economy to ensure …

Phylogenetic Relationships Within The Batagur Complex (Testudines: Emydidae: Batagurinae), Jean M. Capler

Masters Theses

Relationships between 10 species of the batagurine genera Batagur, Callagur, Kachuga, Hardella, and Morenia are discussed based on a cladistic analysis of 35 morphological characters. Ocadia sinensis (Emydidae: Batagurinae) was used as the outgroup species. Four cladograms were produced with a length of 59.0 steps and a 0.75 consistency index. In contrast with previous studies, Hardella and Morenia do not appear as a monophyletic clade. Instead, Hardella is included with the remaining ingroup taxa (exclusive of Morenia) based on five synapomorphies. The present genus Kachuga was determined to be paraphyletic, having excluded the present genera Batagur and Callagur. The pangshura …

An Analysis Of Employee Print Media Content, Michelle M. Accardi

Masters Theses

This content analysis studies an area that has had limited research: university print media. University print media helps maintain communication between management and employees. Past research links three communication categories together: organizing, relationship and change. Organizing is found to be the dominant content category in business newsletters, according to past research.

The uses and gratifications theory, exchange theory and structural-functional theory all play an integral part in the communication process. Continuous two-way comunication between management and each public can lead to a successful organization. Internal communication, wants vs. needs, and finding common ground are additional variables that determine the effect …
