The Effects of Different Percentages of Incentive Pay to Base Pay on Work Productivity

Description: This experiment investigated how different percentages of incentive pay affected performance on a number-entering task. It was hypothesized that the critical factor in incentive pay systems was the absolute amount of money that could be earned in an incentive pay paradigm. A counterbalanced single-subject reversal design was employed to examine effects of incentives on performance. Twelve subjects were used in the experiment with three subjects assigned to one of four experimental paradigms. Tw… more

The Effects of Differential Outcomes on Audio-Visual Conditional Discriminations in Children with ASD

Description: The differential outcomes effect (DOE) refers to an observed increase in rates of acquisition of simple or conditional relations when the contingencies of reinforcement arrange for reinforcers to be uniquely correlated with a particular stimulus or response relative to conditions where the reinforcers are not uniquely correlated with either stimulus or response. This effect has been robustly documented in the literature with nonhuman subjects. This study asked whether the DOE would be observed … more

The Effects of Diphenylhydantoin on the Lymphoreticular Tissues of the Rat

Description: A study was made of the effects of diphenylhydantoin (DPH) and the carrier solution on the spleen, lymph node, and thymus. DPH was injected i.p. at concentrations of 5 and 10 mg./100 gm. for 30 and 60 days. Hematologic effects observed were leucocytosis, neutrophilia, eosinophilia, and lymphopenia. Respiratory measurements of lymph node tissue slices were made using the oxygen electrode method. The carrier solution was found to cause a marked increase in oxygen consumption. A DPH effect on lymp… more

Effects of Disasters on Local Climate Actions: Climate Change Mitigation and Adaptation Actions

Description: This dissertation investigates the effects of natural disasters and political institutions on municipalities' climate change policies. Although most theoretical frameworks on policy adoption highlight the roles of extreme events as exogenous factors influencing policy change, most studies tend to focus on the effects of extreme events on policy change at the national level. Additionally, the existing theoretical frameworks explaining local policy adoption and public service provision do not pay… more

Effects of Discharge Tube Geometry on Plasma Ion Oscillations

Description: This study considers the effect, on plasma ion oscillations, of various lengths of discharge tubes as well as various cross sections of discharge tubes. Four different gases were used in generating the plasma. Gas pressure and discharge voltage and current were varied to obtain a large number of signals. A historical survey is given to familiarize the reader with the field. The experimental equipment and procedure used in obtaining data is given. An analysis of the data obtained is presented al… more

The Effects of Discipline-Based Art Education upon Reading Test Scores of Suburban North Texas Second Grade Children

Description: This study examines the effects that discipline-based art education has upon reading test scores of public school second grade children. The progress in language arts of an experimental group and a control group were followed for two six week grading cycles. The experimental group was treated with DBAE instruction for one six weeks, while the control group received only studio production exercises. Both groups received no art instruction for another six weeks. Gains between mean pre-test and po… more

Effects of Dissipation on Propagation of Surface Electromagnetic and Acoustic Waves

Description: With the recent emergence of the field of metamaterials, the study of subwavelength propagation of plane waves and the dissipation of their energy either in the form of Joule losses in the case of electomagnetic waves or in the form of viscous dissipation in the case of acoustic waves in different interfaced media assumes great importance. with this motivation, I have worked on problems in two different areas, viz., plasmonics and surface acoustics. the first part (chapters 2 & 3) of the disser… more

The Effects of District Expenditure Per Pupil and Low Socio-Economic Status on the Grade 10, 2000 and 2002 Disaggregated Student Performance Scores on the TAAS

Description: Educators can no longer simply look at student totals to distribute instructional dollars. Databased decision-making must be instituted to overcome achievement gaps between white and non-white students. In low-socioeconomic (SES) settings, districts must increase expenditure per pupil (EPP) as low-SES rates rise for all students as district administrators must be in a position to show product rather than process. It was attempted to determine if a positive or negative relationship existed betwe… more

The Effects of EDTA Chelation Therapy on Plaque Calcium and Mineral Metabolism in Atherosclerotic Rabbits

Description: New Zealand albino rabbits exhibited calcified aortic plaques and maximum average serum cholesterol levels of 1200 mg percent after twenty-three weeks on an atherogenic diet (250 to 500 mg percent cholesterol in ten percent corn oil; 200,00 I.U. vitamin D3 per month). One month following termination of the atherogenic diet, rabbits were treated with disodium edetate (Na2EDTA, 50 mg/kg body weight) via the marginal ear vein, on alternating days for a total of twenty infusions each. Aortae were e… more

The Effects of Electrochemical Therapy on Colon-25 Tumors in Balb-C Mice

Description: The purpose of the research was to treat immunodeficient mice, implanted with colon-25 tumors, with continuous and interrupted electrochemical therapy (ECT). ECT involves the placement of two electrodes, an anode near the center of the tumor and a cathode into the tumor periphery. A constant voltage is applied across the electrodes for a given period of time. The data showed that the interrupted and continuous ECT resulted in a decrease in mean tumor growth as compared to that of the sham contr… more
