Item Land Use in Charles County(1962) Langen, John S.; Van Royen, W.; Geography; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)The land use of Charles County does not basically differ from that in the past. Land in forest and land in farms are the two categories of land utilization. The great demand for tobacco on the overseas markets in the early days of the county's history, led to the introduction of this crop. Because of the favorable climate and soils, tobacco became soon the mainstay of the county's economy, a situation which still exists today. The purpose of the thesis was to determine which geographical factors and others accounted for the use of the land. In addition to field work, use was made of detailed statistical data. It was found, that the county could be divided into three sections. In the western section, land in forest was the dominating land use form. In the central section, land in forest and land in farms were about equal in areal extent, whereas in the eastern section, land in farms dominated. The reason was that soils in the western part became exhausted, and a shift to the eastern section took place. Landforms contributed much to the distribution of land in crops, especially for tobacco. Recently, a change in the use of the land is taking place. The encroachment of the Washington Metropolitan area, and the building of a major highway, connecting the North with the South, have induced farmers to sell their lands, which are converted into residential areas.Item Juvenile Delinquency and the Negro in Charles County, Maryland(1966) Seaman, Thomas W.; Lejins, Peter P.; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Are there differences between Negro and white juvenile delinquents? This was the question that constituted the basis for this exploratory study. The objectives of the project were to determine if Negro juveniles were proportionately overrepresented among juvenile delinquents and if there were differences in types of offenses committed by Negro and white delinquents. The differences found were analyzed in the light of socio-economic class differences between Negro and white delinquents. Previous research has tended to indicate that racial differences disappeared when socioeconomic class was held constant. The area selected for the project was Charles County, Maryland, because of the writer's access to court records and knowledge of the area. Delinquency rates were developed to determine if Negroes were proportionately overrepresented among delinquents and/or if lower class juveniles were overrepresented among delinquents. Delinquent offenses were divided into four types: offenses involving theft or attempted theft of property, offenses involving violence, offenses involving the destruction of property, and offenses injurious to the child himself. Delinquency rates were developed for Negro and white delinquents in each socio-economic class for each type of offense. A simple ecological investigation was conducted to determine if there were any significant patterns in the spatial distribution of the delinquents. The findings show that Negro juveniles were not significantly overrepresented among delinquents even though Negro delinquents were overrepresented among lower-lower class delinquents. White delinquents were found to be overrepresented among delinquents from the lower-middle and upper-lower classes. The analyses of types of offenses revealed that types of offenses could be identified with certain levels of the socio-economic structure regardless of race, but that differences existed between Negro and white delinquents within socio-economic classes. The ecological investigation indicated that there was no significant ecological pattern among county delinquents.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 A Comparative Study of Certain Personality Characteristics of College Women Participating in Basketball and Modern Dance(1965) Bird, Anne Marie; Johnson, Warren R.; Health Education; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)Twenty-five college women attending the University of Maryland during the spring semester of 1963 were studied in an effort to determine whether or not there were any identifiable personality characteristics among those (14) who chose to participate in basketball, as compared to those (13) who chose to participate in modern dance. The subjects used in this study voluntarily chose the activity in which they participated. The California Psychological Inventory was used to evaluate the personality characteristics of the subjects. Analysis of the data showed that the basketball group scored significantly higher, at the 5 percent level of confidence, on the community scale. The modern dance group scored significantly higher, at the 5 percent level of confidence, on the scales measuring flexibility and femininity. A comparison of the group means for all other scales proved insignificant at the 5 percent level of confidence.Item An Empirical Analysis of the Determinants of Initial Occupational Choice by Male High School Graduates(1986) Cox, Donald Francis; Brechling, Frank; Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)This dissertation consisted of an empirical analysis of the determinants or initial occupational choice by male high school graduates. The approach used was based on the theory of random utility. According to this approach, the individual selects a particular outcome from a set of possible outcomes based on both observed and unobserved characteristics of the individual and the particular possible outcome. In this analysis, the occupational choice set contained three possible outcomes. These possibilities were civilian sector employment, military service and college enrollment. For empirical analysis, a sample of 1,748 male high school graduates was drawn from the National Longitudinal Survey of Youths (1979-1981). The empirical model consisted of a mixed discrete/continuous simultaneous 4 equation system. Three estimation strategies were used. The first was a sample two stage logit/ordinary least squares procedure. The second was a modified two stage logit/ordinary least squares procedure that corrected for self-selectivity bias. the third strategy consisted of a modified two stage logit/ordinary least squares procedure that corrected for both self-selectivity and choice-based sampling bias. The estimation results indicate that the decision to enlist is most sensitive to the net income of the individual's family and the predicted civilian sector wage. The military experience of the individual's father and the desire to acquire additional training are also important in this decision. In addition, the differences in the estimates across the three estimation procedures illustrate the importance of correcting for sample biases.Item THE RELATIONSHIP BETWEEN SENSATION SEEKING, ANXIETY, SELF-CONFIDENCE AND AIDS-RELATED SEXUAL RISK-TAKING IN A COLLEGE STUDENT SAMPLE(1994) Isralowitz, Stuart Adam; Teglasi, Hedwig; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, MD)The researcher investigated how the personality traits of sensation seeking, anxiety, and self-confidence are associated with AIDS-related sexual risk-taking of college students. It was hypothesized that individuals who exhibited high levels of sensation seeking, low anxiety, and low self-confidence in specific domains would participate in a significant amount of sexual risk-taking. If this were true, then preventive approaches could be geared toward helping risk-takers cope with the characteristics that place them at-risk. The researcher administered the following measures to 313 college students: the Sensation Seeking Scale Form V (SSS V), the Endler Multidimensional Anxiety Scales-Trait (EMAS-T), the Personal Evaluation Inventory (PEI), a modified Sexual Behavior Questionnaire, and a demographic questionnaire. Two aspects of sensation seeking (Disinhibition and Boredom Susceptibility) on the SSS V were significantly associated with AIDS-related sexual risk-taking. High sensation seekers engaged in more sexual risk-taking than low sensation seekers in these areas. In addition, moderate sexual risk-takers only exhibited less anxiety than low risk-takers in the Daily Routines aspect of anxiety on the EMAS-T. Moderate risk-takers displayed greater self-confidence regarding Romantic Relationships than low risk-takers on the PEI. The association between sensation seeking and anxiety was negative. High sexual risk-takers showed a greater worry about getting AIDS and higher perception of AIDS risk than low sexual risk-takers. No gender differences were found in sexual risk-taking. Implications for research included conducting studies regarding sensation seeking and AIDS-related sexual behavior with gay and lesbian college students, and with individuals of college age not attending college. Studies measuring the psychometric qualities of the SSS V and the PEI were also suggested. A practical outcome of this study was the proposed use of an updated measure to assess participation in novel, varied, and risky activities. Clinicians could employ this measure in public schools and college counseling centers, under certain circumstances.Item The Origins and Implementation of the 1992 Nuclear Suppliers Group (NSG) Agreement(2002) Perry, Todd E.; Quester, GeorgeThe 1992 Nuclear Suppliers (NSG) Agreement remains the only multilateral forum, with the exception of the complementary Zangger Committee, in which states capable of supplying nuclear and nuclear-related technologies attempt to constrain the flow of these technologies to countries of proliferation concern. This study reviews the history of multilateral nuclear nonproliferation export control cooperation and complementary international safeguards systems leading up to the conclusion of the 1992 NSG Agreement. This review reveals that nuclear-related crises like the Indian nuclear explosion of the 1974 and the discovery of the Iraqi near-proliferation in 1991 have been the most proximate causes of multilateral reforms, but that U.S. domestic politics has been the primary filter through which these crises have been interpreted and subsequently translated into domestic and multilateral export control arrangements. This study therefore asks the question as to whether or not the "feedback loop" between proliferation-related crises and multilateral export control reform remains in place. To evaluate the main variables responsible for reform and the evolving relationships between them, three increasingly stringent stages of multilateral export controls on nuclear weapons-related technology from 1943 to 1992 are analyzed. These variables are then reviewed for the 1992-2002 period and compared to the three earlier stages of reform to assess the continued relevance of the determinative factors of Cold War-era export control reforms to the export control challenges of the 21st century. This study concludes that the crisis-reform dynamic is unlikely to repeat itself due to changes at the U.S. domestic level, but that knowledgeable bureaucrats and outside experts remain prepared to pursue reform should U.S. leaders attempt to pursue reform in the absence of the public pressures created by a nuclear-related crisis.Item Changing Lifestyles Towards a Low Carbon Economy: An IPAT Analysis for China(MDPI, 2011-12-27) Hubacek, Klaus; Feng, Kuishuang; Chen, BinChina has achieved notable success in developing its economy with approximate 10 percent average annual GDP growth over the last two decades. At the same time, energy consumption and CO2 emissions almost doubled every five years, which led China to be the world top emitter in 2007. In response, China’s government has put forward a carbon mitigation target of 40%–45% reduction of CO2 emission intensity by 2020. To better understand the potential for success or failure of such a policy, it is essential to assess different driving forces such as population, lifestyle and technology and their associated CO2 emissions. This study confirms that increase of affluence has been the main driving force for China’s CO2 emissions since the late 1970s, which outweighs reductions achieved through technical progress. Meanwhile, the contribution of population growth to CO2 emissions was relatively small. We also found a huge disparity between urban and rural households in terms of changes of lifestyle and consumption patterns. Lifestyles in urban China are beginning to resemble Western lifestyles, and approaching their level of CO2 emissions. Therefore, in addition to the apparent inefficiencies in terms of production technologies there is also a lot of room for improvement on the consumption side especially in interaction of current infrastructure investments and future consumption.Item Operational Automatic Remote Sensing Image Understanding Systems: Beyond Geographic Object-Based and Object-Oriented Image Analysis (GEOBIA/GEOOIA). Part 1: Introduction(MDPI, 2012-09-14) Baraldi, Andrea; Boschetti, LuigiAccording to existing literature and despite their commercial success, state-of-the-art two-stage non-iterative geographic object-based image analysis (GEOBIA) systems and three-stage iterative geographic object-oriented image analysis (GEOOIA) systems, where GEOOIA ⊃ GEOBIA, remain affected by a lack of productivity, general consensus and research. To outperform the degree of automation, accuracy, efficiency, robustness, scalability and timeliness of existing GEOBIA/GEOOIA systems in compliance with the Quality Assurance Framework for Earth Observation (QA4EO) guidelines, this methodological work is split into two parts. The present first paper provides a multi-disciplinary Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis of the GEOBIA/GEOOIA approaches that augments similar analyses proposed in recent years. In line with constraints stemming from human vision, this SWOT analysis promotes a shift of learning paradigm in the pre-attentive vision first stage of a remote sensing (RS) image understanding system (RS-IUS), from sub-symbolic statistical model-based (inductive) image segmentation to symbolic physical model-based (deductive) image preliminary classification. Hence, a symbolic deductive pre-attentive vision first stage accomplishes image sub-symbolic segmentation and image symbolic pre-classification simultaneously. In the second part of this work a novel hybrid (combined deductive and inductive) RS-IUS architecture featuring a symbolic deductive pre-attentive vision first stage is proposed and discussed in terms of: (a) computational theory (system design); (b) information/knowledge representation; (c) algorithm design; and (d) implementation. As proof-of-concept of symbolic physical model-based pre-attentive vision first stage, the spectral knowledge-based, operational, near real-time Satellite Image Automatic Mapper™ (SIAM™) is selected from existing literature. To the best of these authors’ knowledge, this is the first time a symbolic syntactic inference system, like SIAM™, is made available to the RS community for operational use in a RS-IUS pre-attentive vision first stage, to accomplish multi-scale image segmentation and multi-granularity image pre-classification simultaneously, automatically and in near real-time.Item Operational Automatic Remote Sensing Image Understanding Systems: Beyond Geographic Object-Based and Object-Oriented Image Analysis (GEOBIA/GEOOIA). Part 2: Novel system Architecture, Information/Knowledge Representation, Algorithm Design and Implementation(MDPI, 2012-09-20) Baraldi, Andrea; Boschetti, LuigiAccording to literature and despite their commercial success, state-of-the-art two-stage non-iterative geographic object-based image analysis (GEOBIA) systems and three-stage iterative geographic object-oriented image analysis (GEOOIA) systems, where GEOOIA ⊃ GEOBIA, remain affected by a lack of productivity, general consensus and research. To outperform the Quality Indexes of Operativeness (OQIs) of existing GEOBIA/GEOOIA systems in compliance with the Quality Assurance Framework for Earth Observation (QA4EO) guidelines, this methodological work is split into two parts. Based on an original multi-disciplinary Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis of the GEOBIA/GEOOIA approaches, the first part of this work promotes a shift of learning paradigm in the pre-attentive vision first stage of a remote sensing (RS) image understanding system (RS-IUS), from sub-symbolic statistical model-based (inductive) image segmentation to symbolic physical model-based (deductive) image preliminary classification capable of accomplishing image sub-symbolic segmentation and image symbolic pre-classification simultaneously.
