Rural Electrification And Development In South Korea, Terry Van Gevelt
Rural Electrification And Development In South Korea, Terry Van Gevelt
Research Collection College of Integrative Studies
In fifteen years, South Korea went from providing only 12% of rural households with electricity to providing 98% of rural households with electricity for lighting and productive uses. This paper provides an analysis of rural electrification and development in South Korea from 1965 to 1979 and finds that rural electrification contributed to a significant increase in rural household income levels and improved the quality of life in villages substantially. At the same time, rural electrification did not benefit the poorest quartile of rural households, increased economic and social inequality, led to a significant increase in household debt, and accelerated migration …
Optimal City Hierarchy: A Dynamic Programming Approach To Central Place Theory, Wen-Tai Hsu, Thomas J. Holmes, Frank Morgan
Optimal City Hierarchy: A Dynamic Programming Approach To Central Place Theory, Wen-Tai Hsu, Thomas J. Holmes, Frank Morgan
Research Collection School Of Economics
Central place theory is a key building block of economic geography and an empirically plausible description of city systems. This paper provides a rationale for central place theory via a dynamic programming formulation of the social planner's problem of city hierarchy. We show that there must be one and only one immediate smaller city between two neighboring larger-sized cities in any optimal solution. If the fixed cost of setting up a city is a power function, then the immediate smaller city will be located in the middle, confirming the locational pattern suggested by Christaller. We also show that the solution …

Urban Planning Process: Can Technology Enhance Participatory Communication?, Rojin Vishkaie, Richard Levy, Anthony Tang

Oftentimes, within the urban planning process, urban planners and GIS experts must work together using desktop Computer-Aided Design (CAD) and Geographic Information System (GIS). However, participatory communication and visualization which are important in the urban planning process, are not a central focus in the design of current computer-aided planning technologies. This study tends to provide an understanding of technological challenges and complexities urban planners and GIS experts encounter while engaging in a participatory environment during the urban planning process. This study also explores the perceptions of urban planners and GIS experts about the potential impact and usefulness of interactive surfaces …
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang
The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang
Research Collection School Of Economics
The fundamental law of highway congestion states that when congested, the travel speed on an expanded expressway reverts to its previous level before the capacity expansion. In this paper, we propose a theory that generalizes this statement and finds that if there exists a coverage effect, that is, the effect of longer road length on traffic conditional on capacity, then the new equilibrium travel speed could be lower than its previous level. Given the fundamental law, the theory predicts that the elasticity of traffic to road capacity is at least 1. We estimate this elasticity for national expressways in Japan …
Seasonal Dynamics Of A Suburban Energy Balance In Phoenix, Arizona, Winston T. L. Chow, Thomas J. Volo, Enrique R. Vivoni, G. Darrel Jenerette, Benjamin L. Ruddell

Observations of local-scale urban surface energy balance (SEB), which include fluxes of net all-wave radiation (Q*), and eddy covariance measurements of sensible (QH) and latent heat (QE) were collected in an arid Phoenix, AZ suburb from January to December 2012. We studied diurnal variations in SEB partitioning over four distinct seasons: winter, equinoxes, and summer; the latter period is further subdivided into (1) months prior to and (2) months occurring during the North American Monsoon. Largest flux densities were observed in summer, with most available energy partitioned into QH. Much less energy is partitioned into QE, but this term is …
Community-Based Management Of Tricholoma Matsutake: A Case Study Of South Korean Mountain Villages, Terry Van Gevelt
Community-Based Management Of Tricholoma Matsutake: A Case Study Of South Korean Mountain Villages, Terry Van Gevelt
Research Collection College of Integrative Studies
Tricholoma matsutake (S. Ito and S. Imai) Singer commercialisation provides significant economic benefits to rural communities, mainly in China, Japan and South Korea. Recently, a growing body of research has questioned the impact of commercialization on harvesting behavior and the supply of matsutake. One key question arising from this literature is whether or not community-based management (CBM) has a positive impact on matsutake supply. I surveyed nine mountain villages in Gangwon and North Gyeongsang provinces in South Korea. Four villages were found to have begun CBM of matsutake in the mid-1980s to early-1990s. All four villages continued to engage in …
