Hazardous Waste Policy: a Comparative Analysis of States' Enforcement Efforts

Hazardous Waste Policy: a Comparative Analysis of States' Enforcement Efforts

Date: May 1995
Creator: Okere, Lawrence N. (Lawrence Ndubuisi)
Description: The major purpose of this study is to analyze hazardous waste enforcement by the states as mandated by the Resource Conservation and Recovery Act of 1976 (RCRA). States' historical enforcement records from 1980 to 1990 are analyzed to determine the pattern of variations in enforcement. This study differs from previous studies on hazardous waste regulation in that it employs longitudinal data from 1980 to 1990 to analyze states' enforcement effort.

HIV and Duty to Protect: a Survey of Licensed Professional Counselors and Physicians

HIV and Duty to Protect: a Survey of Licensed Professional Counselors and Physicians

Date: May 1995
Creator: Johnson, Laura K. (Laura Kimberly)
Description: This study was designed to investigate what course of action therapists and physicians report they would take in reconciling their conflicting duties to maintain confidentiality and protect third parties from harm in HIV-related situations. The physicians surveyed were licensed to practice medicine in Texas and board certified in Internal Medicine. The therapists surveyed were licensed professional counselors in Texas and members of one of three selected divisions within the Texas Counseling Association. A survey instrument developed by the researcher was mailed to 200 subjects randomly selected from each group.

In Vitro Studies of Nuclear Changes in Mammalian CNS Neurons Subjected to Rapid Acceleration Impact Injury

In Vitro Studies of Nuclear Changes in Mammalian CNS Neurons Subjected to Rapid Acceleration Impact Injury

Date: May 1995
Creator: Wolf, Amy
Description: An in vitro model of Rapid Acceleration Impact (RAI) Injury was used to study the effects of multiple impact (220 g/impact, 3-5 sec intervals) trauma on cultures of murine CNS cells. Investigations with spinal cord cultures showed that 1) multiple impacts delivered tangential to the plane of cell growth caused neuronal death (12% after 3 impacts to 46% after 10 impacts); 2) multiple impacts delivered normal to the plane of cell growth were much less effective (8% dead after 10 impacts); 3) most neuronal death occurred within 15 minutes after injury 4) morphological changes observed included increased nuclear prominence and somal swelling; and 5) pretreatment with ketamine (0.1mM) reduced cell death from 51 to 14% and reduced somal swelling. Identical studies performed on cortical cultures revealed minimal differences between the two tissues in their response to multiple tangential impacts.

Intrinsic and Extrinsic Adaptation in a Simulated Combat Environment

Intrinsic and Extrinsic Adaptation in a Simulated Combat Environment

Date: May 1995
Creator: Dombrowsky, Steven P. (Steven Paul)
Description: Genetic algorithm and artificial life techniques are applied to the development of challenging and interesting opponents in a combat-based computer game. Computer simulations are carried out against an idealized human player to gather data on the effectiveness of the computer generated opponents.

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

Date: May 1995
Creator: May, Brack M. (Brack Miles)
Description: The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.

Italian Influences in the Corellisirende Sonaten of Telemann

Italian Influences in the Corellisirende Sonaten of Telemann

Date: May 1995
Creator: Chang, Young-Shim
Description: George Philipp Telemann is often thought of an experimenter with many nationalistic styles during the course of his career. His Corellian Sonatas demonstrate this facet of his work in their employment of Corelli's manner, and the cultivation of the Italian style. Telemann's Corellian sonatas are stylistically close to those of Corelli, and they do not appear to vary widely from the church and chamber sonatas of Corelli; Telemann fused the two sonata types in that dance elements are found in the church sonatas and the abstract elements of the church sonatas are inserted into the chamber sonatas. In addition to the amalgamation of internal elements, Telemann also experimented with the external features, such as the alternation of tempo and the four movement stereotype.

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type

Date: May 1995
Creator: Halbrook, Courtney (Courtney Ann)
Description: Growth of Corbicula fluminea was monitored in the laboratory. Three experiments were conducted. Experiment I utilized three substrates and one food type. Experiment II utilized three substrates and two food types. Experiments I and II were conducted to determine if substrate type or food type effected growth. Experiment III used no substrates, one food type and was conducted to determine growth response to different types of water. Clams were maintained in three substrates: sand, gravel and clay. Clams were also maintained without substrate. Growth was monitored by measuring shell length (mm) and recording the weight (mg) of clams over a period of thirty days. At the end of the test period data were evaluated for normality and homogeneity.
