  • This paper aims to provide empirical evidence required to describe the level of achievement by analyzing students' item response in NAEP implemented in the United States in 2001. The geography assessment in the NAEP is aimed to test students of 4th, 8th, and 12th grades, and consists of content dimension and cognitive dimension, The former includes 'space and place' 'environment and society' and 'spatial dynamics and connections,' and the latter includes 'knowing' 'understanding' and 'applying,' The level of achievement is defined as three levels for each grade: Basic, Proficient, and Advanced. In this paper, descriptions of achievement is derived inductively from an analysis of student's responses to the items which were selected by using item-mapping method. As a result, there is a great difference between the level of achievement derived empirically from students' response and the level of achievement designed principally suggested by the expert committee. The former could have a contribution to the improvement in geography curriculum.

  • To address the requirements of gap analysis for species protection, as well as the needs of state and federal agencies for detailed digital land cover, a 43-class map at the vegetation alliance level was created for the state of Kansas using multi-temporal Thematic Mapper imagery. The mapping approach included the use of three-date multi-seasonal imagery, a two-stage classification approach that first masked out cropland areas using unsupervised classification and then mapped natural vegetation with supervised classification, visualization techniques utilizing a map of small multiples and field experts, and extensive use of ancillary data in post-hoc processing. Accuracy assessment was conducted at three levels of generalization (Anderson Level I, vegetation formation, and vegetation alliance) and three cross-tabulation approaches. Overall accuracy ranged from 51.7% to 89.4%, depending on level of generalization, while accuracy figures for individual alliance classes varied by area covered and level of sampling.

  • Human capital and higher education have been increasingly emphasized with the rise of a knowledge-based economy. Cities are recognized as places to attract human capital and spur economic development. Educated workforce supply is one of the critical parts to sustain IT industries, which have been leading recent economic development. This paper examines factors affecting geographies of educated workforce supply from colleges and universities to companies in U.S. metropolitan areas through questionnaire survey and interviews with IT companies and IT-related programs at colleges and universities. The results show that: (1) physical proximity between IT companies and colleges/universities enhances the degree of educated workforce supply from colleges/universities to IT companies; (2) IT companies which seek more specialized and rarer expertise recruit the workforce from colleges or universities over longer distance; (3) colleges and universities which offer a higher degree have geographically more extensive supply of educated workforce to IT companies than those which offer a lower degree; and (4) large IT companies have more geographically extensive supply of educated workforce to colleges/universities than small IT companies.

  • The proportion of overweight and obese individuals in the United States has been continuously increasing up to recently. Many studies related to obesity have concentrated on jurisdictional levels of aggregation, making it very difficult to dearly illustrate at risk regions. In other words, little research has been conducted in relation to spatial patterns considering spatial dependency and heterogeneity by spatial autocorrelation models over space. In response, this research analyzes spatial patterns between overweight/obesity and risk factors, such as high blood pressure and diabetes, over space. Specifically, the Moran''s I and Geary''s C will be conducted for global and local measures. What is more, the Ordinary Least Square (OLS) linear regression and Geographically Weighted Regression methods will be applied to identify spatial dependency and spatial heterogeneity. Data provided by the Behavioral Risk Factor Surveillance System (BRFSS) have Body-Mass Index (BMI) rates, containing 4 rates of under, healthy, overweight, and obesity. In addition, high blood pressure and diabetes rates in the United States will be used as independent variables. Lastly, we are confident that this research will be beneficial for a decision maker to make a prevention plan for obesity.

  • This study attempts to understand new immigrants' socio-economic adaptation by linking them with the restructuring economies in large US metropolitan areas. Selecting Los Angeles, New York, Chicago, and Atlanta, we examine the industrial distribution of employed Hispanic and Asian immigrant groups with respect to the industrial change experienced between 1980 and 1990, and residential concentration represented by higher location quotients. The findings are that new immigrant groups are employed in overall industrial sectors close to that of total population and their large residential concentrations are displayed near downtown as well as outlying areas. These suggest that new immigrant groups experience different socio-economic adaptation from those generalized in the previous European immigrants, concentrated in manufacturing sector and near downtown area. This study proposes that divergent economic restructuring across metropolitan areas and new immigrants' backgrounds should be considered for better understanding of immigrants' economic adaptation in the current economic restructuring and its spatial manifestation in the US contexts.

  • Recently, attention has been drawn to the issue of local community revitalization. In the U.S., CDC(Community Development Corporation) has become a main vehicle for revitalizing dilapidated inner-city communities. Using the case of Philadelphia in the U.S., this paper investigates the way in which local community revitalization or downtown revitalization can be successfully achieved through the formation of social capital and public-private partnership. Futhermore, exploring the cases of West Philadelphia CDC and University City, this paper seeks to provide insight into the dynamics of successful community development. In order to examine the dynamics, this paper focuses on local governance in terms of both the reciprocal partnerships and the close networking among participating agents. The implications of the case studies of this research for the Korean context would be that the bottom-up approach starting from the local-scale community revitalization and local governance is very crucial and indispensable for the sustainable regional or national development.

  • Humans have been searching for more comfortable places for centuries. The comfort concept which is related with vitality in Pungsu is closest to science. The comfort concept was introduced as being based upon measurable human physiological and psychological reactions. Two classification nomograms, the comfort index and the wind effect index were identified. The Pungsu concept can be applied in America, and one of them is North Cemetery located in the town of Hampton in northeastern Connecticut not far from Storrs campus, the University of Connecticut. The human reaction to comfort not only physiologically but also individually is various in various climate region. It is important to search for more comfortable places or to make up for less comfortable places with Pungsu as the adaptive strategy for the comfort.

  • It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.

  • Residential segregation is often considered to be one of the social problems that intensify urban inequality This study reviews three different frameworks about the causes of residential segregation and tests their validity in the real world. The review focuses on racial/ethnic residential segregation in U.S. cities since it has been blamed for persistent socio-economic gap among racial/ethnic groups. The three different segregation frameworks include 'spatial assimilation' that attributes segregation to low degree of assimilation and acculturation, 'place stratification' to discriminatory practices in the housing and mortgage markets such as steering, blockbusting, and redlining, and 'resurgent ethnicity' to racial/ethnic preference in residential choice, particularly in-group attraction. As an effort to test their validity, the paper examined residential pattern changes of the four major Asian nationality groups through 1990s and found that their residences got decentralized but re-cluster in some selected suburbs. This supports 'resurgent ethnicity' largely and 'spatial assimilation' only partly.

  • Using MD Property View database on 15 counties in Maryland in the U.S., this study attempts to explore the estimation process on the housing development capacity under the Maryland's urban growth management policy known as the Smart Growth Initiatives. This study also seeks to draw the implications of the estimated development capacity by individual counties on successful implementation of the urban growth management policy. The finding shows that this region has land for residential use enough to accommodate growth for the next 30 years. However, contrary to the goal of the Smart Growth Initiatives, a majority of development capacity is located not only outside the Priority Funding Area designated by the Smart Growth Initiatives but also at counties that are located far away from the major metropolitan area. In addressing this problem, the state does not need to either abolish or immediately expand the Priority Funding Area. Rather, the state requires local governments to include housing elements in their comprehensive planning, to provide periodic estimates on housing and employment capacity, and to establish and manage database on the location and the capacity of developable land.
