Climatic Preference, Jeffrey T. Lutz
The Geographical Bulletin
Researchers within the discipline of geography seek to achieve an enhanced comprehension of man's perception of the world. Therefore, environmental perception is a subject of great consequence to geographers. Understanding of the sources of environmental variance perception in is essential to an understanding of variation in man's environmental behaviors. 1 The mental image is one of the major determinants of spatial behavior; and spatial images area an individual's cognitive representation of the spatial environment, and are a summary of what he considers meaningful about the environment.' Climate is a strategic factor affecting man's responses to the complex environment, and climate …

The Diffusion Of Transportation Effects In An Urban Network, David Burik
The Geographical Bulletin
Large urban centers are served by transport networks which consist of a great number of links and nodes. Predicting what the effects of the construction of a proposed link, the abandonment of superfluous elements, or the improvement of existing links will be on the traffic flows over the entire system is currently a timeconsuming and expensive undertaking. It is nevertheless, a necessary step investment appraisal. It is for proper often the case that the amount of available capital will only allow for the completion of a relatively small scale projects. The cost of a full traffic study to assess the …

The Study Of A Service Area, Mary Wegner
The Geographical Bulletin
Valparaiso, with a population of 20,900 as of 1970, is a city which serves the inhabitants of Porter County in northwest Indiana. The exact variety and combination of its services are not duplicated anywhere else in the world. In addition to the expected municipal functions for a city of its size (e.g. street repair, police and fire protection, mail and newspaper deliveries, shopping, and recreation facilities), Valparaiso also performs functions that other towns in the immediate vicinity do not provide. Examples of such functions include serving as the county seat of Porter County; housing the only Lutheran university in the …

A Geographic Analysis Of Crime Rate In Southwestern Michigan: 1967·1973, James F. Lee
The Geographical Bulletin
In the last five years the study of the spatial dynamics of crime has become an important subfield of the geographic discipline. Numerous, well known studies have appeared, written by geographers and non-geographers alike, dealing with the geography of crime in general or with specific areal units.' While this abundance of research has been fruitful, it has, nonetheless, been haphazard. An attempt to remedy this situation was recently put forward by Phillips, who has identified several well defined research frontiers open to geographers of crime.2 Suggested by Phillips are four areas in which geographers should concentrate their crime research efforts: …

This office does not receive much mail even though there has always been an open Invitation to our readers to comment on the quality of the effort. In general, the comment which does come is favorable. However, the letter on the opposite page arrived recently. All I know is that It was mailed in Silver Springs, Maryland on Dec. 20, 1977 and after reading it I wished the writer a "Merry Christmas." Now, wasn't that gracious? At least it is time to make a few things clear again. Some time ago the Executive Board of Gamma Theta Upsilon agreed that …

Public Recreation On Private Lands, George A. Vanotten, Richard M. Highsmith Iii
The Geographical Bulletin
Not long ago most citizens of the United States had easy access to rural areas. Wooded lands, forests and pastoral settings were available to the greater portion of the populous. During the past one hundred years however, the nation's population has changed from being primarily rural to overwhelmingly urban. Therefore, the average resident of a large metropolitan area must travel considerable distance to gain access to rural recreation sites. For people In the lower Income ranges, the cost of traveling to distant recreation sites Is often prohibitive. Furthermore, demand for outdoor recreation has Increased In recent years.

Precipitation Efficiency Under Varying Atmosph Eric Con Oitions, Jeffrey T. Lutz
The Geographical Bulletin
A strategic step in the assessment of water availability for a given location is the prediction of the amounts and temporal variability of precipitation. Considering the present state of the art, long-term meteorological forecasts of precipitation are not adequately accurate or reliable for predictive use. Since most predictions are based upon simple statistical analyses of past rainfall records, they are inherently unsatisfactory In that preci pitation production processes are ignored. Determination of the causes of spatial and temporal variations in the amount of precipitation produced by particular atmospheric systems in specific locations is important in assessing water availability. A valuable …

"County Seats In The Middle Western Urban System, Thomas J. Baerwald
The Geographical Bulletin
The county seat played an important role in the development of the Middle Western urban system. Studies of the county seat's most visible expression noted the importance of the courthouse in the establishment of Middle Western urban places. Price asserted, "The courthouse was [the town's] reason for being, its first central function, the seat of its creator. Even had no town been laid off, a community of businesses and residents would have gathered around it." The frequent use of "county seats" to designate middle level places of the Middle Western urban hierarchy, places smaller than gateway cities but larger than …

Urban Heat Islands Across Major U.S. Cities: The Relationship Between Surface Temperature & Socioeconomic Status, Sarah Irish, Eliza Hammari, Megan Green
FHSS Mentored Research Conference
The urban heat island (UHI) effect is a geospatial phenomenon prevalent across major U.S. cities which has significant implications for public health, energy consumption, and environmental quality. To better understand the impacts of UHI on various communities, we analyzed the correlation between surface heat temperatures and median household income across five large cities and three urban climates (arid, humid, and tropical) in the U.S.. We gathered data from the U.S. Census Bureau and other sources to create maps using ArcGIS Pro. Based on the maps and statistical analysis, UHI intensity is correlated with socioeconomic status. Further research is recommended to …

A Survey Of Sampling Methods For Hyperspectral Remote Sensing: Addressing Bias Induced By Random Sampling, Kevin T. Decker, Brett J. Borghetti
Faculty Publications
Identified as early as 2000, the challenges involved in developing and assessing remote sensing models with small datasets remain, with one key issue persisting: the misuse of random sampling to generate training and testing data. This practice often introduces a high degree of correlation between the sets, leading to an overestimation of model generalizability. Despite the early recognition of this problem, few researchers have investigated its nuances or developed effective sampling techniques to address it. Our survey highlights that mitigation strategies to reduce this bias remain underutilized in practice, distorting the interpretation and comparison of results across the field. In …

A Method For Describing The Problem Of Physician Distrbution In Rural Areasralph Ekwall, Ralph Ekwall
The Geographical Bulletin
In recent years much attention has been given to the problem of physician shortage and physician maldistribution. The first is controversial and not all the experts believe that it exists except as a part of the maldistribution problem. There is a fundamental agreement that a problem of maldistribution exists. The general nature of the problem is that physicians are distributed too densely in small cities and large city suburbs and too sparsely in the inner city and rural areas. It is not the intent of this presentation to offer a solution to the problem, but to offer a method for …
