Internship at the Aquarium of the Americas
This report documents an internship that was served at the Aquarium of the Americas in New Orleans, Louisiana from 16 January 1989 through 7 April 1989. The purpose of the internship was to observe the administration of the internship organization in order to perform a managerial analysis. Another goal was to engage in administrative tasks in order to gain practical experience at a managerial level. The Aquarium of the Americas is a department of the Audubon Institute, which, in turn, is supervised by the Audubon Park Commission. As a result, those organizations are also included as subjects for analysis. The internship is a requirement of the graduate program in Arts Administration at the University of New Orleans

Media and Music: A Qualitative Content Analysis of the African American Educational Experience as Portrayed in Black-Produced Films, Songs and Print Publications
African Americans have been treated unequally and unfairly by the media. This issue deserves national attention while stressing the need for more positive messages of African Americans. The intent of this study was to examine how Black produced films, Hip-Hop songs and magazines portray the African American high school educational experience. The theory that guides this paper is critical media literacy. Critical media literacy provides an opportunity to evaluate, understand and critically analyze all forms of media. A qualitative content analysis was used to determine how African Americans are depicted by Black producers, directors and writers. Central questions worth exploring were: (a) How is the African American experience in high school portrayed by Black producers, directors and writers? (b) In what ways do film, Hip-Hop and magazines illustrate the usefulness of the educational experience for social mobility (financial attainment, career vocation attainment, and school attainment)? and (c) Do certain types of media portray the African American high school experience in a more positive or negative light? The results of the study show that African Americans high school students are often portrayed as violent, criminal, poor, uneducated, overly sexual and athletes in popular films, Hip-Hop and magazines. These negative cultural stereotypes remain a concern for many African Americans.Keywords: African American educational experience, critical media literac

The ionospheric response over the UK to major bombing raids during World War II
The Earth’s ionosphere is subject to disturbance from above (via solar variability and space weather effects) and from below (such as tectonic activity, thunderstorms and sudden stratospheric warmings). Identifying the relative contribution of these effects remains challenging, despite recent advances in spacecraft monitoring near-Earth space. Man-made explosions provide a quantifiable proxy for natural terrestrial sources, enabling their impact on ionospheric variability to be studied. In this paper, the contribution of ground-based disturbances to ionospheric variability is investigated by considering the response of the ionospheric F2-layer over Slough, UK, to 152 major bombing raids over Europe during World War II, using a superposed epoch analysis. The median response of the F2 layer is a significant decrease in peak electron concentration (~0.3 MHz decrease in foF2). This response is consistent with wave energy heating the thermosphere, enhancing the (temperature dependant) loss rate of O+ ions. The analysis was repeated for a range of thresholds in both time of bombing before the (noon) ionospheric measurement and tonnage of bombs dropped per raid. It was found that significant (~2-3σ) deviations from the mean occurred for events occurring between approximately 3 and 7 hours ahead of the noon ionospheric measurements and for raids using a minimum of between 100 and 800 tonnes of high explosives. The most significant ionospheric response (2.99σ) occurred for 21 raids up to 5 hours before the ionospheric measurement, each with a minimum of 300 tonnes of explosives. To ensure that the observed ionospheric response cannot be attributable to space weather sources, the analysis was restricted to those events for which the geomagnetic Ap index was less than 48 (Kp < 5). Digitisation of the early ionospheric data would enable the investigation into the response of additional ionospheric parameters (sporadic E, E and F1 layer heights and peak concentrations). One metric ton of TNT has an explosive energy of 4.184 109 joules, which is of the same order of energy as a cloud to ground lightning stroke. Since the occurrence of lightning has distinctive diurnal and seasonal cycles, it is feasible that a similar mechanism could contribute to the observed seasonal anomaly in ionospheric F-region electron concentrations. Further investigation, using less extreme examples, is required to determine the minimum explosive energy required to generate a detectable ionospheric response
