Item Internal Migration to Osaka Prefecture, Japan(1956) Lewis, David Michael; Hoffsommer, Harold; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Item Battery Studies with Particular Reference to Organic Depolarizers(1955) Monson, William L.; Huff, W. J.; Chemical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Since Volta's invention of the first primary cell, using silver and zinc, numerous other cell combinations have been studied, covering a wide variety of anode and cathode materials. The latter have included both inorganic and organic substances capable of electrochemical reduction, although, historically, organic cathode materials have received very much less attention than the inorganic. It was the purpose of this investigation to study the actual behavior of a selected number of quinones as depolarizers in primary cells. Performance of experimental cells was compared with cells of the usual dry cell composition but of the same size and construction as cells of experimental composition. The results show that certain substituted anthraquinones possess good depolarizing ability as measured by discharge voltage and coulombic capacity. Energy output in some cases was higher than that of the manganese dioxide control cells (zinc anodes in all cases) because of higher effective coulombic capacities. A qualitative study of the effect of substituents on the discharge voltages of various quinones showed that cell working voltages were much more sensitive to quinone substitution than were the calculated reversible potentials. Also, in the case of nitro-substituted anthraquinones more coulombic capacity was obtained than could be accounted for by the simple reduction to the corresponding hydroquinone. The possibility of a reduction of the nitro-group of this compound was considered. Substances investigated were benzoquinone, naphthoquinone, anthraquinone, and certain of their derivatives, using various electrolytes. The size of the experimental cells was such that about 0.2 gram of the various depolarizers could be studied conveniently.Item History of Public Education in Baltimore from 1860-1890(1943) Krausse, Harry W.; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Several studies of public education have been made in Maryland and Baltimore; among them being "History of Education in Maryland," "Secondary Education in Maryland before 1800," "Public Educational Work in Baltimore," "Baltimore, 1870 to 1900: Studies in Social History." However, there is no detailed account of the development of the Baltimore City school system covering the period of the Civil War and the years following this war. During this time significant educational hlstory was made as events of great educational importance took place, which events were to affect the future of the Baltimore public schools as well as the future of children attending these schools.Item Henry Theodore Tuckerman as Revealed in his Published Works(1959) Ellsworth, Richard Grant; Beall, Otho T.; American Civilization; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)Henry Theodore Tuckerman, as revealed in his published works, was, in many ways, a model of the mid-nineteenth century American. In his travel accounts, his historical and biographical scholarship, his social and political attitudes, his artistic and literary criteria, is revealed his sincere allegiance to the Romantic Idealism which dominated his day. This allegiance is shown in his belief in the fundamental goodness and inevitable progress of mankind; in his basic individualism, an almost transcendental egocentrism, which mystically identified the human soul with God, and interpreted self-reliance in terms of intuitional supranatural apprehension; in his dichotomization of his realities, separating the Ideal from the practical, the intuitive from the reasonable, the commonplace from the beautiful, the here and now from the distant and the past; in his acceptance of Nature as the representation of the Ideal, and of the feminine as the symbol of the Beautiful; in his fealty to emotion and sympathy as the mystical keys to all human relationships; in his strict and didactic morality; and in his professed national ism and proclamation of divine purpose and destiny in America . Yet, he was conservative in his personal refusal to become involved in reformism, in either outright abolitionism or feminism; in his determined and maintained attitude of Brahmin aloofness from "the herd" and "the multitude"; in his willingness to submit himself to governmental mandate, to support, at least nominally, what was legal and generally accepted; and in his overly-developed and almost unnatural reticence which prevented his from ever achieving that intense ego-exploration imperative within the Romantic philosophy. His published works reveal him to have been profoundly influenced by three major factors in his private live: his mother's death, his Italian residence, and his deep aversion for the commercial life. Possibly, in his need for social (and, especially, feminine) acceptability, his adoration of the ideal woman, and, perhaps, his easy acceptance of the sentimental and the emotional. His Italian travels and residence introduced him to the artistic experience and instilled in him a determination to devote his life to the Beautiful and to the encouragement of its creation and appreciation. And His aversion to the common precepts and standards demanded by American commercialistic enterprise influenced this decision, and shaped his life philosophy in its declaration of an over-stressed materiality in American life, and consequent under-development of the spiritual and the intellectual. With the exception of some of his better poems, Tuckerman's travel accounts best reveal his personal attitutdes and feelings toward his time and his world. As a scholar, Tuckerman read widely, but not deeply. His recorded perceptions almost always appear to be reflections of the parallel conclusions of his greater contemporaries. But he considered his theories his own, and, although he often documented a though or a conclusion, he never admitted to an intellectual debt or spiritual guidance. Tuckerman's greatest significance is in his constant effort to popularize the Beautiful, and thus to enrich American life. He sought always to broaden the public perceptions, to increase American aesthetic appreciation, to combat American reoccupation with commercialism. He was ever the propagandizer for good taste and cultural cultivation. His published works all evidence this. As a recorder of travels, he encouraged an appreciation for European cultural achievement. As a historian and biographer, he was narrative and moralistic. As a literary and art critic, he ever diligently encouraged the writer and the artist, and always sympathetically explained and interpreted to their audience. As a poet and author in his own right, although he often proved sympathetic with the sentimental demands of his age, he, nevertheless, in spite of such lapses, always strove to broaden the public outlook toward the Beautiful and the Cultural as he perceived them to be. That his audience appreciated his effort is readily apparent in his evident contemporary popularity. But his death and the end of his social influence, the broad standard and contemporary nature of his appeal , and the swiftly changing public interest, all combined to prove his fame ephemeral, and to banish him to a modern obscurity unworthy of his sincere intent and effort, and obvious contemporary accomplishment. Henry Theodore Tuckerman deserves to be remembered not only for his yet-standard biographical scholarship, and his service as a historian of art and artists in America, but also for his exemplary thought and attitude, the cultured reflections of the literary and artistic standards of mid-nineteenth century America.Item Adult Education in the Social Planning of a Civic Organization(1934) Hostetler, Alice Watts; Cotterman, H.F.; Education; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)This study deals with adult education in the social planning of a civic organization. The problem is to determine the nature and extent of adult education which is the outgrowth of community planning. The study is made in order to assemble and present in usable form facts which may assist persons promoting adult education, program makers in adult organizations, and community leaders in one line or another of community betterment. More specifically, it is the purpose of the study to examine in detail the work of the Montgomery County Civic Federation of Montgomery County, Maryland, in order to discover the higher forms of adult education of informal types which accrue from the several activities of a single civic organization of recognized influence in a rural-suburban area, as these are manifest in the records of the federation and its member associations, and in changes and developments in this area. The activities of the federation, as recorded in the minutes over eight years of its existence, were examined in detail and classified under five major subjects, each having many minor topics. The major divisions are used as chapter titles and the findings, which include studies made by the federation and developments within the county, are presented under these subjects to reveal the amount and kind of adult education in social planning. The study begins with a description of the locale, Montgomery County, Maryland, which includes its location, history, governmental structure, and population. In Chapter II., the aims, history, structure, and functioning of the Montgomery County Civic Federation are described. The facts revealed by this survey of the eight-year program of the federation and of the area it influences are classified and presented as five chapters dealing with adult education in Public Welfare, County Projects, Public Schools, Government, and Outside the County. The study ends with a summary based on the findings.Item British Influence in Mesopotemia 1900-1914(1957) Amin, Abdul Amir; History; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)Although several European powers showed early interest in the Persian Gulf and Mesopotamia, its natural land extension, Britain was more successful than her rivals in exploiting commercial and political possibilities in the area, and over a period of three centuries gradually emerged as the dominant foreign power there.Item Heats of Combustion and Formation of Some Simple Aliphatic Amines(1958) Jaffe, Irving; Chemistry; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Item A Comparison of Irony in W.M. Thackeray and Thomas Mann (Until 1918)(1950) Mohr, William; Foreign Study; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)In our comparison of the irony found in Mann and Thackeray we will first discuss irony in its more concrete aspects, ironic content and then ironic form. Further, and particularly in connection with Mann, we will speak about the nature and position of the artist. This topic is actually another aspect of ironic content, but it is such an important problem in Mann's early works that it deserves special consideration. And finally, we will return to Mann's metaphysical irony.Item STANDARDS OF LIVING OF MARYLAND FARM FAMILIES(1938) Teeter, Viola; Metzger, J.E.; Welsh, Claribel; DeVault, S.H.; Family Science; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)This thesis represents the results of a standard of living study of seventy-two farm families in Carroll County, Maryland, for the year beginning in the summer of 1936 and ending in the summer of 1937. The data were collected in the summer of 1937. Carroll County is located in the northern part of the state and borders on Frederick County on the west, Howard County to the south, Baltimore County on the east and borders on Pennsylvania to the north. See Figure 1. The county is very irregular and comprises an area of 447 square miles of 286,080 acres. Topographically, the land is gently rolling to hilly with many streams. There is an excellent drainage system in the county. The area is adapted to the production of field corn, sugar corn, and other general crops, being a fertile agricultural region. Oil of Chenopodium or "worm seed oil" has been produced on many of the farms in Carroll County for the past 100 years, and is a very lucrative crop. Dairying is the principle type of farming in the county. Even though the county is definitely agricultural, several clothing, shoe, and canning factories, and a distillery flourish, thus supplying a ready market for farm produce. The county has an excellent system of public records and is served by three railways-- the Baltimore and Ohio, Western Maryland, and the Pennsylvania. No part of the county is over ten miles from a railroad. It has a splendid home market and is ideally located in relation to two of the principle markets of the East, Baltimore, and Washington. There are two local colleges to serve the youth of the county-- Blue Ridge College, located at New Windsor, and Western Maryland College, located at Westminster. The average acreage per farm was 106 acres, of which 83 acres were under cultivation. The number of tenant farms surveyed was so few that no breakdown of farms was made on an owner-operated and tenant-operated basis. The analysis was based on averages for all farms. The length of tenure on the same farm varied from 1 year to 54 years, the average tenure being 20 years. Distribution of families by length of tenure on the same farm is shown in Table 1. The purpose of the study was to determine as accurately as possible the amount of cash available for family living; now the farm families use their incomes; to judge their standards of living; and determine the adequacy of their diets according to accepted standards. The information was obtained by means of a questionnaire and a personal interview with each family. The questionnaire, or schedule, was explained and was left with the homemaker and farm operator, so that an accurate record of food consumed by the family during the week, and number of meals served to individual members of the household could be recorded. At the end of the week the worker returned for the schedule and recorded the data as given by the homemaker and farm operator.Item An Economic Study of 128 Dairy Farms on the Upper Eastern Shore of Maryland(1938) Smith, Carl B.; DeVault, S.H.; Hamilton, A.B.; Agricultural & Resource Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md)This study analyzes the second year's survey or 128 dairy farms, representative of the dairy industry on the Upper Eastern Shore of Maryland. This area, which includes Cecil, Kent, Queen Anne's, Talbot, and Caroline counties, is a part of the Philadelphia Milk Shed.
