The Effects Of Public Commitment And Group Feedback Of Curbside Recycling, Iser Guillermo Deleón Dec 1993

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 …

The Slip Velocity Of Coating Formulations Using The High-Shear Viscometer, Daniel Parker Krieger Dec 1993

The Slip Velocity Of Coating Formulations Using The High-Shear Viscometer, Daniel Parker Krieger

Masters Theses

When using a cup and bob viscometer, it has long been recognized that errors in the viscosity measurement can arise from several factors, among them slip. Slip is a phenomenon which occurs when there are slipping layers in the fluid under shear, causing a non-uniform velocity gradient to be generated across the gap of the cup and bob viscometer. A layer of fluid at either the bob or cup wall moves faster than the adjoining layers, causing the slipping effect. This leads to a low viscosity calculation for the fluid.

In this study, experiments with coating formulations were conducted using …


Evaluation And Implementation Of Asynchronous Adders, Poornima Y. Shankarreddy Dec 1993

Evaluation And Implementation Of Asynchronous Adders, Poornima Y. Shankarreddy

Masters Theses

The need for high speed addition is forcing digital system designers to trade off space. If speed is used as a criterion to judge adders, then the Ripple Carry Adder (RCA) and the Carry Look Ahead Adders (CLAAD) will rank last and first respectively. On the other hand, if space is used, then the order of these two is reversed. The rest of the adders rank between these two. This paper evaluates RCA, CLAAD, and some of the other well documented adders. Both space and speed are used to judge the merits of each of these, and whether or not …

Effects Of Cocaine On Fixed-Ratio Responding Of Rats: Modulation By Required Response Force, Malath Makhay Dec 1993

Effects Of Cocaine On Fixed-Ratio Responding Of Rats: Modulation By Required Response Force, Malath Makhay

Masters Theses

The effects of acute cocaine administrations (5. 6 to 32 mg/kg) were determined in rats responding under a multiple fixed-ratio 15 fixed-ratio 15 schedule of food delivery. The minimum response effort required in one schedule component was 25 g, whereas in the other component it was 200 g. Cocaine produced generally dose-dependent decreases in rate of responding and increases in pre-ratio pause times under each component. There was, however, a significant interaction between force and drug dose, and the magnitude of drug effects were larger in the component requiring 200 g for lever operation. Although a number of other parameters …

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 …


Karma In Theodicy, Joji Watanabe Dec 1993

Karma In Theodicy, Joji Watanabe

Masters Theses

The study of religion explicates fascinating aspects of human history. From the past through the present to future times, in every area of human history a person's religious views provide his or her specific world view: How to consider the meaning of life or world. In a sense, suffering has come up as one of major problems in religion. This is because how a group of people finds release from suffering explains the specific aspect of each religious tradition.

With the above as a basis, theodicy was set not as God's justice in the Judeo-Christian tradition but as a broad …

Primary Coolant Flow Characteristics As It Exits The Palisades Reactor, Gregory Alan Baustian

Masters Theses

During fuel cycles 9 and 10 at the Palisades Nuclear Power Plant, new phenomena have been observed using the resistance temperature devices installed in the reactor coolant piping. Oscillations in the temperature readings have been observed leading to the assumptions that there is temperature stratification of the coolant in the reactor hot-legs and that the coolant rotates as it leaves the reactor. In addition, oscillations in the bulk coolant flow within the two hot legs have been postulated. This report outlines work performed using computational fluid dynamics modelling which predict the observed and assumed flow characteristics of the Palisades reactor …

Contracts In Conflict: Perestroika And The Decline Of Soviet Legitimacy, Karl Glenn Hokenmaier Aug 1993

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 …


A Classification Of Ecosystem Desertification Using Satellite Imagery, Dzheltyrbas Gulf, 1980-1989, Marni D. Cavis Aug 1993

A Classification Of Ecosystem Desertification Using Satellite Imagery, Dzheltyrbas Gulf, 1980-1989, Marni D. Cavis

Masters Theses

This study focused on the development of a land cover classification method for the Dzhiltyrbas Gulf region southeast of the Aral Sea in the former Soviet Union. Desertification of the region was mapped based on ecosystem descriptions taken from a database defining four stages of desertification. Landsat MSS images (bands 1, 2, and 4) were used as the basis for classification. Standard unsupervised and supervised classification methods did not distinguish the level of detail required to map each stage of desertification in each ecosystem. Therefore, the ecosystems had to be defined and classified as separate entities (based on SBI and …

This research examines the philosophy of William Morris, how this influenced his founding of the Society for the Protection of Ancient Buildings (S.P.A.B.) in 1877, and how this Society functioned in Victorian Great Britain. Two case studies, specifying the S.P.A.B.'s involvement with Westminster Abbey and Edinburgh Castle, are highlighted to detail how the Society operated in secular and ecclesiastical situations. The research concludes with an appraisal of the S.P.A.B. in the twentieth century.

This research emphasizes primary source materials, such as letters and annual reports, from the S.P.A.B archive in London. These materials demonstrate how the S.P.A.B. met their goals …


Community Development Corporations And Their Contributions To Democracy In Chicago, Carl E. Hanssen Aug 1993

Community Development Corporations And Their Contributions To Democracy In Chicago, Carl E. Hanssen

Masters Theses

Community development corporations (CDCs) are non-profit, neighborhood-based, real estate developers. They share a common mission to improve social conditions in communities where they work. CDCs were developed based on two distinct models: (1) an intervention model, and (2) a grass-roots model.

This work was predicated on a theory of political science: high levels of social conditions correspond with high levels of democracy. High levels of democracy will be demonstrated by high voter participation. The work of CDCs and their impact on communities in Chicago was analyzed to test this theory.

Four CDCs and corresponding communities were chosen for this study. …

Inhibition Of Cytochrome P-450 But Not Neutrophil Depletion Prevents The Pulmonary Toxicity Associated With 1-Nitronaphthalene, Steven Michael Green

Masters Theses

1-Nitronaphthalene (1-NN) is an environmental contaminant that has been shown to cause pulmonary toxicity in rodents. To examine the contribution of cytochrome P-450 to the metabolism and subsequent toxicity of 1-NN, rats were pretreated with chloramphenicol, a suicide substrate of P-450. To determine if inflammation plays a role in 1-NN toxicity, rats were pretreated with cyclophosphamide to deplete neutrophils. In both experiments, morphological analysis of the lower airways was performed with light and electron microscopy. A second group of animals was examined for biochemical indicators of inflammation and cell damage. The parameters examined were cell content, protein content and lactate …
