Measurements of V/STOL aircraft noise mechanisms using pressure cross-correlation techniques in a reverberant wind tunnel

A 3.8 cm. model jet was operated in a wind tunnel with cross-flow in order to determine the effect on jet noise radiated characteristics. A method was developed for the determination of noise radiating characteristics of sources within reverberant wind tunnels; cross-correlation measurements were used. The averaging time in the cross-correlation is determined by the amount of background noise within the wind tunnel. It was found that cross-flow increases the radiated noise by 10 db. There was some indication of downstream radiation exceeding the sideline radiation

R.A.V. v. City of St. Paul: The Continuing Confusion of the Fighting Words Doctrine

Communication contributes to the marketplace of ideasI which is the only way to promote the discovery of truth in society. The importance of communication has led the United States Supreme Court to herald freedom of expression as the matrix, the indispensable condition, of nearly every other form of freedom. Indeed, the Court protects few other constitutional rights with such fervor. First Amendment protection is not absolute, however, and the United States Supreme Court consistently has asserted that certain forms or classes of expression may be regulated without violating the Constitution. Generally speaking, the Court has carved exceptions to First Amendment protection when the expression makes no contribution to the marketplace of ideas. One such class of unprotected speech is fighting words. Unfortunately, the Court has experienced great difficulty distinguishing fighting words from merely offensive ideas that clearly are entitled to the highest level of First Amendment protection

Acoustic interference fields in the ocean

Two areas of underwater acoustics are investigated: ocean-bottom scattering and acoustic fields in geometrically dispersive sound channels. The purpose is to describe and provide an understanding of the physical mechanisms in these two areas by comparing analyzed results from ocean experiments with theoretical computations. Experiments using directive 19.5-kHz transducers illustrate temporal and spacial behavior of signals scattered from the ocean bottom. The signals fluctuate, as a function of acoustic geometry, in linear relation to source and receiver motion and to signal frequency. Spacial structure of the acoustic field depends on frequency and acoustic geometry and is independent of motion and bottom roughness. Data supporting these observations are included as well as data showing the effects of bottom type on the scattered returns, that is, the existence of subbottom returns in some data. Volume-scattering-strength profiles are also provided from data obtained in these experiments. Continuous-wave (CW) and impulsive sources covering frequencies 5 to 260 Hz were towed and deployed respectively over ranges up to 3000 km, with reception on fixed hydrophones. Analyses of measured propagation losses of these low-frequency acoustic signals in the dispersive channel provide insights into the nature of the propagation and the acoustic channel. Both the CW signals and the arrivals of the impulsive signals are analyzed in terms of transmission loss, convergence-zone structure, source-motion effects, interference structure, and channel characteristics. The systematic variation (internal tides) of the medium and its influence on the interference field are discussed. The state of modeling, both simple and complicated, is reviewed and compared with results of the ocean experiments. Relationships are provided between this work and the broader field of underwater acoustics. Suggested areas for future research are made

Addressing the Disparaity of Outcomes for Economically Disadvantaged Students at Central Intermediate School: An Applied Research Study Related to the Implementation of AVID Process

The purpose of this applied action research study was to close the achievement gap between economically disadvantaged (ED) students and their non-disadvantaged peers (non-Ed) through the implementation of the Advancement Via Individual Determination (AVID) system of processes. This study utilizes both quantitative and qualitative data to answer four core research questions. While the initial implementation of the plan failed to attain the targeted goal of closing the achievement, there were positive indicators for future success. ED students did appear to be effectively engaged with the AVID implementation. This engagement was validated through data about student participation in key AVID strategies, classroom observations, lesson plan analysis, and focus group interviews. Data collected also revealed implementation problems which serve as a basis for recommendations for continuation and improvement of the ongoing AVID implementation. Lastly, data revealed strong reasons to believe the AVID implementation had a positive impact on collaborative organizational capacity toward bettering outcomes for all students

Includes extensive research on preschool nationwide, the state of California, and in Pomona. Within the paper a new preschool curriculum and specific teacher practices are discussed. Intended as a model for a new school. or to be adapted for use in educational policy

Teaching Today\u27s Diverse Student Population in Schools

The primary purpose of this study was to investigate teacher candidates\u27 attitude and knowledge level toward the adequacy of their teacher training for meeting the needs of a diversified school population and to make recommendations for any restructuring in a University teacher training program. A survey research method using a convenience sample size of (N = 240) was used to collect data for this study. The sample of 240 participants included graduate and undergraduate teacher candidates who had completed student teaching and alumni from the last five years. A self-developed questionnaire with 35 Likert-type questions and four open-ended questions was used to collect data for this study. Eighty-three percent of the 240 surveys were scorable, leaving 200 scorable surveys. One-way analysis of variance and Chi-square were used to analyze the relationship between attitude, knowledge, and several demographic and experiential variables such as ethnicity, clinical experience, level of education, and discipline of specialization. Additionally, the open-ended questions were analyzed using themes and inter-rater reliability. The hypotheses were tested using a significance level of .05. The results showed that although the overall attitudes of teacher candidates toward a diversified population was positive, they felt there was a need for additional training in order to successfully teach a school population made up of students from various ethnic, religious, and language backgrounds. The results of this study also clearly indicate there is a need to offer more courses that better prepare teacher candidates to effectively teach a population of students who come from increasingly diversified backgrounds
