    The final phase of a satellite synthesis project is described. Several methods for generating satellite positionings with improved aggregate carrier to interference characteristics were studied. Two general methods for modifying required separation values are presented. Also, two methods for improving aggregate carrier to interference (C/I) performance of given satellite synthesis solutions are presented. A perturbation of the World Administrative Radio Conference (WARC) synthesis is presented

    The Twentieth Century Record of Inequality and Poverty in the United States

    When the twentieth century is viewed as a whole, no clear trend in income inequality emerges. Inequality was high and rising during the first three decades and peaked during the Depression. It fell sharply during World War II and remained at the lower level in the 1950s and 1960s. From the 1970s through the mid-1990s inequality steadily increased to levels not seen since World War II, though well below those during the first three decades. The rate of poverty exhibited a long-run downward trend from about 60–70 percent in the earlier years of the century to the 12–14 percent range in recent years, with considerable fluctuation around this secular trend. Changes in inequality were produced largely by demographic and technological changes, the growth and decline of various industries, changes in patterns of international trade, cyclical unemployment, and World War II. The primary drivers of the rate of poverty were economic growth and factors that produced changes in income inequality, particularly demographic change and unemployment. Public policy has reduced the market-generated level of inequality, but since 1950 has had little effect on the trend in inequality. Prior to 1950, the growth of government, and particularly the introduction of a broadly based income tax during World War II, coincided with and partly produced the sharp downward shift in inequality of that era. Government had little effect on poverty rates until 1950. Public income transfer programs have reduced poverty rates appreciably in recent decades. Since World War II, when they have been on a large enough scale to matter, changes in tax and transfer policy have tended to reinforce market-generated trends in inequality and poverty rather than offset them.

    Onboard sampling and the rockfish and lingcod commerical passenger fishing vessel industry in Northern and Central California, January through December 1994

    The Central California Marine Sport Fish Project has been collecting angler catch data on board Commercial Passenger Fishing Vessels (CPFVs) fishing for rockfish or lingcod since 1987. The program depends on the voluntary cooperation of CPFV owners and operators. This fourth report in a series presents data collected in 1994, refers to historical data from 1987 to 1993, and documents trends in species composition, angler effort, catch per unit effort (CPUE), and, for selected species, mean length and length frequency. Angler catches on board central and northern California CPFVs were sampled from 14 ports, ranging from Crescent City in the north to Port San Luis (Avila Beach) in the south. Technicians observed a total of 2053 anglers fishing on 237 CPFV trips. These observed anglers caught 24,731 fish of which samplers determined 22,615 were kept. Over 63% of these fish were caught at Monterey or Morro Bay area ports. Only 18 of the 53 species each comprised at least one percent of the catch. The top ten species in order of abundance were blue, yellowtail, rosy, chilipepper, canary, and black rockfishes, lingcod, and widow, starry and greenspotted rockfishes. Blue and yellowtail rockfishes together comprised approximately 44% of the observed catch. Overall, rockfishes represented 32 species or 60% of the 53 identified species. In general, 1994 data showed continued evidence of sustainability of the CPFV rockfish fishery with a few exceptions for some species in each port area sampled. We identified areas of concern for three nearshore species (black, blue, and brown rockfishes), three offshore species (bocaccio, chilipepper, and widow rockfish), and two wide-depth range species (canary and yelloweye rockfishes). Declining trends in CPAH in at least one port area were identified for each of these species except black and blue rockfishes, some of which may be related to natural variability in year class strength or stock movement. Mean length decreased in at least one port area for black, blue, brown, and canary rockfishes and chilipepper, although for black rockfish and chilipepper this was attributed to increased recruitment of juveniles. Positive trends identified included increased CPAH for black rockfish in the San Francisco and Monterey areas, for canary rockfish in the San Francisco area, and for brown rockfish in the Morro Bay area. Total northern and central California CPFV catch estimates, based on logbook data and adjusted by sampling data and compliance rates, indicated that port area-specific decreases have occurred since 1988 for yellowtail rockfish and lingcod (San Francisco), chilipepper (Monterey), and blue rockfish (Monterey and Morro Bay). The competing influences of the nearshore commercial hook-and-line fishery were apparent when comparing relative species composition to that of the CPFV fishery. Declines in CPAH in the CPFV fishery for some shallow water species, such as brown rockfish in the Bodega Bay area, may be related to increased commercial fishing effort. (98pp.

    Roles of Social Media in the Black Lives Matter Movement During COVID-19

    By definition social movements reflect unique times in history. To fully grasp the implications of a movement the social and political climate that induce them must be understood. An intersectional model should be used when framing and studying the Black Lives Matter (BLM) movement, a modern descendant of both the NAACP and Civil Rights movement. From its inception, BLM has utilized social media as an important tool by coining #BlackLivesMatter, a hashtag that frequently comes to life offline as BLM organizers use it as a call for action and mobilization. The accessibility of social media made its role in the BLM movement even more vital during the 2019-2020 COVID-19 pandemic. With continued police brutality and the murders of Breonna Taylor, George Floyd, and countless more, the need for change was as pressing as ever during the pandemic. This comprehensive literature review on BLM\u27s antecedents and social media\u27s role in activism along with quantitative analyses of BLM affiliated Instagram pages highlights social media\u27s diverse roles in social movements and its use as a powerful tool for mobilization during and prior to a global health crisis

    Charles Peirce's Theory of Scientific Method

    Get PDF
    This book is an attempt to understand a significant part of the complex thought of Charles Sanders Peirce, especially in those areas which interested him most: scientific method and related philosophical questions. It is organized primarily from Peirce's own writings, taking chronological settings into account where appropriate, and pointing out the close connections of several major themes in Peirce's work which show the rich diversity of his thought and its systematic unity. Following an introductory sketch of Peirce the thinking and writer is a study of the spirit and phases of scientific inquiry, and a consideration of its relevance to certain outstanding philosophical views which Peirce held. This double approach is necessary because his views on scientific method are interlaces with a profound and elaborate philosophy of the cosmos. Peirce's thought is unusually close-knit, and his difficulty as a writer lies in his inability to achieve a partial focus without bringing into view numerous connections and relations with the whole picture of reality. Peirce received some of the esteem he deserves when the publication of his Collected Papers began more than thirty-five years ago. Some reviewers and critics, however, have attempted to fit Peirce into their own molds in justification of a particular position; others have disinterestedly sought to present him in completely detached fashion. Here, the author has attempted to understand Peirce as Peirce intended himself to be understood, and has presented what he believes Perice's philosophy of scientific method to be. He singles out for praise Peirce's Greek insistence on the primacy of theoretical knowledge and his almost Teilhardian synthesis of evolutionary themes. Primarily philosophical, this volume analyzes Peirce's thought using a theory of knowledge and metaphysics rather than formal logic

    The University of Louisville Photographic Archives : the first fifty years.

    The University of Louisville Photographic Archives celebrated its fiftieth anniversary in 2012. Now holding over two million images within hundreds of discreet collections, the Photographic Archives was started by Robert J. Doherty who was responsible for acquiring the very significant Roy E. Stryker Papers and Standard Oil (New Jersey) social documentary collections . First curator, Don Anderson, collected fine print photography with work by photographers like Ralph Eugene Meatyard. The extensive archives of local commercial studios Caufield & Shook and The Royal Photo Company ensured the preservation of Louisville’s visual legacy and long-time curator James “Andy” Anderson grew the collection tremendously. Assistant David Horvath published an influential study on the deterioration of acetate negatives, and darkroom manager Bill Carner worked closely with local photographer Stern Bramson to put together an influential travelling exhibition. The Archives has transitioned from traditional darkroom to digital imaging, and makes many photographs available online through Digital Collections. The Photographic Archives continues to mount regular exhibits, host lectures, and make available collection items for teaching and research purposes to university students and the general public
