Mapping of wildlife habitat in Farmington Bay, Utah

Mapping was accomplished through the interpretation of high-altitude color infrared photography. The feasibility of utilizing LANDSAT digital data to augment the analysis was explored; complex patterns of wildlife habitat and confusion of spectral classes resulted in the decision to make limited use of LANDSAT data in the analysis. The final product is a map which delineates wildlife habitat at a scale of 1:24,000. The map is registered to and printed on a screened U.S.G.S. quadrangle base map. Screened delineations of shoreline contours, mapped from a previous study, are also shown on the map. Intensive field checking of the map was accomplished for the Farmington Bay Waterfowl Management Area in August 1981; other areas on the map received only spot field checking

Development of a lithium secondary battery separator

A nonporous membrane based on the polymerization of 2,3-dihydrofuran followed by crosslinking in situ was prepared. The material is compatible with rechargeable Li battery components and, when swollen with an appropriate solvent such as tetrahydrofuran, exhibits separator resistance and Li transport equivalent to Celgard

Attitudes of Elementary Teachers Toward Participation and Representation in Decision-Making

It was the purpose of this study to investigate the attitude of elementary teachers toward direct participation and representative participation in educational decision-making. A population of elementary teachers from six elementary schools were given an attitude survey concerning involvement. The results of this study suggested that elementary teachers attached more importance to direct participation than representative decision-making concerning areas of instructional leadership. Teachers were more dispersed in their attitudes toward direct and representative participation in the areas of administrative leadership, school-community relations, and professional self-improvemen

Forward Myth: Military Public Relations and the Domestic Base Newspaper 1941-1981

This dissertation explores the evolution of domestic military base newspapers from 1941-1981, a timeframe that encapsulates the Second World War, Korean War, and Vietnam War, as well as interwar and postwar years. While called “newspapers,” the United States military designed these publications to be a hybrid of traditional news and public relations. This dissertation focuses on three primary aspects of these newspapers: the evolution of the format, style, and function of these papers; the messages editors and writers crafted for and about the “common” soldier and American; and the messages for and about members of the non-majority group. Sometimes printed on private presses with ad revenue generated by civilian newspaper ad sellers, these papers sometimes marked a unique marriage between the military and traditional media outlets. However, the local presses had no control over content. That privilege went to each base’s commanding officer. Despite the wide swath of people with control over content, these papers looked the same, and in some cases carried shared stories from various government-run “news” agencies. On their pages could be found both news of the day and identity building stories and editorials, all of which conspired to inform and to a greater or lesser degree nudge readers to conclusions of what the creators of the papers thought it meant to be an American, a soldier, or the member of a racial or gender minority. Though tasked with functioning as both a journalistic and public relations vessel, these publications were inconsistent as purveyors of both news and propaganda. However, each provides a wealth of knowledge about the development of the American identity, and dominant concepts of majority and minority, as well as the integration of public relations and journalism into the military in the 20th Century

Barriers to reducing climate enhanced disaster risks in least developed country-small islands through anticipatory adaptation

© 2014 The Authors. Small Island Developing States (SIDS) classified as Least Developed Countries (LDCs) are particularly vulnerable to the projected impacts of climate change. Given their particular vulnerabilities, climate adaptation investments are being made through both national and international efforts to build the capacity of various sectors and communities to reduce climate risks and associated disasters. Despite these efforts, reducing climate risks is not free of various challenges and barriers. This paper aims to synthesise a set of critical socio-economic barriers present at various spatial scales that are specific to Least Developed Country SIDS. It also aims to identify the processes that give rise to these barriers. Drawing on theories from natural hazards, a systematic literature review method was adopted to identify and organise the set of barriers by focussing on both academic papers and grey literature. The data revealed a notable lack of studies on adaptation within African and Caribbean LDC-SIDS. In general, there was a paucity of academic as well as grey literature being produced by authors from LDC-SIDS to challenge existing discourses related to adaptation barriers. The most common barriers identified included those related to governance, technical, cognitive and cultural. Three key findings can be drawn from this study in relation to formal adaptation initiatives. Firstly, the lack of focus on the adaptive capacity needs of Local Government or Island Councils and communities was a key barrier to ensure success of adaptation interventions. Secondly, international adaptation funding modalities did little to address root causes of vulnerability or support system transformations. These funds were geared at supporting sectoral level adaptation initiatives for vulnerable natural resource sectors such as water, biodiversity and coastal zones. Thirdly, there is a need to recognise the significance of cultural knowledge and practices in shaping adaptive choices of communities in SIDS

Experimental validation of a two-dimensional shear-flow model for determining acoustic impedance

Tests were conducted to validate a two-dimensional shear-flow analytical model for determining the acoustic impedance of a liner test specimen in a grazing-incidence, grazing-flow environment. The tests were limited to a test specimen chosen to exhibit minimal effects of grazing flow so that the results obtained by using the shear-flow analytical model would be expected to match those obtained from normal-incidence impedance measurements. Impedances for both downstream and upstream sound propagation were generally consistent with those from normal-incidence measurements. However, sensitivity of the grazing-incidence impedance to small measurement or systematic errors in propagation constant varied dramatically over the range of test frequencies

A mathematical model for simulating noise suppression of lined ejectors

A mathematical model containing the essential features embodied in the noise suppression of lined ejectors is presented. Although some simplification of the physics is necessary to render the model mathematically tractable, the current model is the most versatile and technologically advanced at the current time. A system of linearized equations and the boundary conditions governing the sound field are derived starting from the equations of fluid dynamics. A nonreflecting boundary condition is developed. In view of the complex nature of the equations, a parametric study requires the use of numerical techniques and modern computers. A finite element algorithm that solves the differential equations coupled with the boundary condition is then introduced. The numerical method results in a matrix equation with several hundred thousand degrees of freedom that is solved efficiently on a supercomputer. The model is validated by comparing results either with exact solutions or with approximate solutions from other works. In each case, excellent correlations are obtained. The usefulness of the model as an optimization tool and the importance of variable impedance liners as a mechanism for achieving broadband suppression within a lined ejector are demonstrated
