Anisotropy of the permittivity field inferred from aspect-sensitive radar echoes

An attempt is made to draw some quantitative conclusions regarding the anisotropy of the clear-air back-scattering mechanism based on the measured variation of echo power with zenith angle. The measurements were made by the SOUSY group of the Max Planck Institute for Aeronomy at Lindau, FRG. They installed their 47-MHz transmitter and antenna feed in the 300-meter diameter reflector at Arecibo. The resulting 1.7-degree beam was stepped successively through seven 1.7-degree intervals from 1.7 to 11.7 degrees in zenith angle, obtaining about four minutes of data at each setting. This procedure was carried out in an eastward pointing azimuth and in a northward pointing azimuth, the entire set of measurements consuming an hour and twenty minutes. Range resolution was 150 meters

Visual direction finding by fishes

The use of visual orientation, in the absence of landmarks, for underwater direction finding exercises by fishes is reviewed. Celestial directional clues observed directly near the water surface or indirectly at an asymptatic depth are suggested as possible orientation aids

Time Portals, Love Machines, Land Oracles: Hybrid Geography and the Situated Digital

London‐based digital art collective Furtherfield creates events and space that encourage cultural flowering through the celebration of difference and otherness. Executive director Tim Waterman, a senior lecturer in landscape history and theory at the Bartlett School of Architecture, University College London, takes us on a journey, starting with the organisation's inception, then projecting us into the future with an outline of its projects for the next few years

Omaha Public High Schools\u27 Graduates Attending UNO

During the 1986-87 school year, the University of Nebraska at Omaha/Omaha Public Schools (UNO/OPS) Liaison Committee requested a study to determine how high school graduates from the Omaha Public Schools were progressing in their college careers at UNO. The author was asked to work with Paul Malcom of the Research Department of Omaha Public Schools to determine how the study might be conducted. Possible research questions were shared with the committee. The author met with Malcom to obtain lists of names of high school graduates. Earlier, OPS conducted a survey of its high school graduates and developed a list of high schools graduates who reported attending UNO. More than one-third of the names listed as attending UNO were not found in UNO records. Of the one-third missing from UNO records, half had arranged to send American College Test (ACT) scores to UNO, although they had not registered for classes. Apparently, some students who intended to go to UNO decided to work for a period of time before they registered at the university. (The follow-up study with its self-reporting procedures presented too many problems, and was not used in this study.

Program Evaluation of the Calvin Ed-U-Care, Inc.

Calvin Ed-U-Care Center is a child development facility designed to provide quality day care to children who are toddlers (under age 3) up to age 12. Organized and incorporated in 1969, the Center is housed in the Calvin Memorial Presbyterian Church at 3105 North 24th Street, Omaha, Nebraska 68110. Mrs. Flossie Miller was its first director; Mrs. Carmen Parson has been director since 1971. Mr. William Grayson, assistant director, has been in his position since 1970. The Center is designed to provide a safe environment for children of working mothers in the low-income community. Virtually all of its clients are from welfare families, and the majority of the children come from homes where the mother is the single parent

A Case Study in the Development of Educational Training Programs

The purposes of the report are twofold: (1) to provide a final report of the contractor for the records and accountability of the Teacher Corps, and (2) to provide insights into the nature of development-a case study that should be helpful to educational planners in other organizations
