A Geographic Analysis Of Crime Rate In Southwestern Michigan: 1967·1973, James F. Lee Apr 2025

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: …


The Study Of A Service Area, Mary Wegner Apr 2025

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 …

The Geographical Bulletin

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 Apr 2025

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.

"County Seats In The Middle Western Urban System, Thomas J. Baerwald Apr 2025

"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 …


Precipitation Efficiency Under Varying Atmosph Eric Con Oitions, Jeffrey T. Lutz Apr 2025

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 …

A Survey Of Sampling Methods For Hyperspectral Remote Sensing: Addressing Bias Induced By Random Sampling, Kevin T. Decker, Brett J. Borghetti Apr 2025

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 …

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 Method For Describing The Problem Of Physician Distrbution In Rural Areasralph Ekwall, Ralph Ekwall Apr 2025

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 …

The Evaluation Of Four Time Intervals Applied To A Synoptic Weather Situation In The United State, Fred E. Kohle

The Geographical Bulletin

synoptic meteorology almost always utilize the easily acquired National Weather Service weekly series of daily weather maps, issued every 24 hours at 7 A.M. eastern standard time (E.S.T.). These daily surface maps provide students with weather data from hundreds of weather stations in the continental United States. Students can use each map to compare and contrast weather patterns affecting several different parts of the country. A sequence of these daily maps allows students to attempt general weather forecasting using well-known weather relationships associated with the model middle latitude cyclone. They can then evaluate their forecasts by referring to the next …


Application Of 700 Millibar Synotic Climatology To Drought Analysis, B. Dey Apr 2025

Application Of 700 Millibar Synotic Climatology To Drought Analysis, B. Dey

The Geographical Bulletin

Large areas of the earth's surface experience occasional climatic fluctuations. Such fluctuations, integral to the weather system, often lead to drought or flood, and this influences crop production and commodity prices. Drought is a contributor to economic, social, and, on occasion, even political instability in both commercial and subsistence agricultural econ­omics. Particularly affected are areas such as India, China, parts of Europe, and the American Great Plains which include the Canadian "Prairies". Because of its dominantly agricultural economy, and because of its location well within a zone of frequent drought, the Canadian Prairies section has been selected for study. Past …


Diffusion Of The Decision To Drain Agricultural Land In Delaware County, Indiana, T. Silas Kasambira, Jr. Apr 2025

Diffusion Of The Decision To Drain Agricultural Land In Delaware County, Indiana, T. Silas Kasambira, Jr.

The Geographical Bulletin

The amount and quality of land are vital production factors in agriculture. In some Indiana counties, the agricultural land resource base is limited by the presence of excess water. The decision to drain potential agricul­tural land in Delaware County, In­diana, and the subsequent diffusion of that innovation has increased the amount and quality of land available for agriculture. Draining agricultural land is a practice which began in the eastern United States and diffused rapidly across the country during the 1800's. The practice was introduced into northern Indiana, which has a great deal of flat, marshy terrain as early as 1850. …

Jonas Wenger Hoover - 1889-1979 Dr. Commeaux, Malcolm Commeaux

The Geographical Bulletin

Jonas Wenger Hoover, a faculty member at Arizona State University from 1924 to 1943 died recently at the age of 90. His life was somewhat like a roller coaster, reaching highs and lows; for the first half of his life he was considered a gifted, in­telligent, and well-rounded man, and he was highly regarded as an author and teacher, but for much of his life he lived in obscurity and near the bottom of society. He is a forgotten man today, but his life can be a lesson to us all. Mr. Hoover was considered gifted in several respects. He …


Social Gaps & Urban Divides: How Social Factors Shape Economic Disadvantage In American Cities, Parker J. Peterson, Ruth Kerry Apr 2025

Social Gaps & Urban Divides: How Social Factors Shape Economic Disadvantage In American Cities, Parker J. Peterson, Ruth Kerry

FHSS Mentored Research Conference

This research examines the relationship between nonmarriage, education, and socioeconomic disadvantage across census tracts in Boston, Los Angeles, and Salt Lake City. Statistical analyses reveal significant differences in never-married proportions between cities, with strong correlations between nonmarriage and community disadvantage. Even when controlling for other factors, nonmarriage remains a significant predictor of disadvantage, though spatial regression shows education is the strongest predictor in Boston.


Community Land Governance In Liberia: Implications For Tenure Security And Land Concessions, Julia R. Entwistle, Hanson Nyantakyi-Frimpong Apr 2025

Community Land Governance In Liberia: Implications For Tenure Security And Land Concessions, Julia R. Entwistle, Hanson Nyantakyi-Frimpong

Geography and the Environment: Faculty Scholarship

Throughout rural Africa, the intersection of customary traditions and statutory governance has often led to overlapping jurisdictions and conflicts over community land rights. In Liberia, this dynamic is particularly evident in the rise of commercial land concessions. This article examines the Liberian government’s approach to community land rights and its impacts on land tenure security, especially in the context of these concessions. This study employs a discourse analysis of Liberian land use policies alongside qualitative data from in-depth interviews with community members living near large-scale plantations. Despite historical erosion of community land rights, Liberian communities have adapted statutory frameworks to …

Prenatal Exposure To Pm2.5 Concentration And Risk Of Preterm Birth In New Mexico; A Seasonal Pattern And Spatio-Temporal Modeling., Onyedikachi J. Okeke

Mathematics & Statistics ETDs

This study investigates the association between prenatal PM2.5 exposure and preterm birth risk in New Mexico (2014–2021). Using descriptive statistics, time series models, and spatial analyses, findings show an average preterm birth rate of 14.87 per 1,000 live births, with moderate correlation (r = 0.727) between PM2.5 levels and very preterm births. While traditional models revealed no significant global effect, spatial methods such as Geographically Weighted Regression (GWR) and Multiscale GWR uncovered strong spatial heterogeneity. PM2.5 effects varied by county (coefficients: -0.00154 to 0.00150), with clustering evident in 2018–2019 (Moran’s I = 0.155–0.174). Results highlight the limitations of global models …


No. 39: Considering The Migration And Food Security Nexus In African Cities, Jonathan Crush, Zack Ahmed Apr 2025

No. 39: Considering The Migration And Food Security Nexus In African Cities, Jonathan Crush, Zack Ahmed

Migration and Food Security (MiFOOD) Network

International migration and food security are still treated as separate policy and research domains, yet they are deeply intertwined in the African urban context. This paper unbundles the nexus between migration and urban food security by examining how migrants and refugees navigate food systems, cope with vulnerabilities, and deploy resilience strategies to mitigate food insecurity. As rapid urbanization reshapes African cities, migrants are becoming actors in informal food economies, both as consumers and vendors. However, economic exclusion, weak social protection, and precarity often expose them to heightened food insecurity. The paper explores how migrant food security is shaped by urban …

No. 38: Informal Female Food Vendors, Covid-19, And Post-Pandemic Recovery In Kisumu, Kenya, Silvia A. Odhiambo, Patrick Mbullo Owuor, Doreen Obondo, Janet Anyango Onyango, Joyce Kiplagat, Elizabeth Onyango

Migration and Food Security (MiFOOD) Network

While there is substantial literature on the effects of COVID-19 on formal businesses, limited evidence exists on the impacts of the pandemic on informal female-owned enterprises. Additionally, no studies have explored the role of post-pandemic recovery strategies in meeting the unique challenges experienced by the informal food vendors in secondary cities in the Global South. In this paper, we explore the impacts of COVID-19 and the post-pandemic recovery strategies on female informal food vendors in Kisumu, the third largest city in the western region of Kenya. The study adopted qualitative methods – in-depth and key informant interviews and focus group …

No. 37: Harnessing Diaspora Finance For Climate Resilience In Africa, Eunice Annan-Aggrey

Migration and Food Security (MiFOOD) Network

As climate change accelerates, the costs of adaptation are rising sharply. This escalation comes at a time when financial inflows to developing countries – such as official development assistance and foreign direct investment – are declining. Meanwhile, the global political climate is becoming unfavourable to sustained climate financing commitments. In this context, the role of remittances in supporting climate adaptation and mitigation in developing countries has attracted growing interest. This paper broadens the lens to examine diaspora finance more holistically, encompassing not only remittances but also diaspora investments and knowledge transfer. It explores the potential of these various diaspora finance …


The Landowner As Change Agent In Rural Modernization: An Ecuadorean Example, Gene N. Franckowiak Apr 2025

The Landowner As Change Agent In Rural Modernization: An Ecuadorean Example, Gene N. Franckowiak

The Geographical Bulletin

In an era of impressive governmental and institutional support for rural modernization plans in developing countries, the privately financed, small-scale project can easily escape attention. A concentration of private funds and individual effort in small communities or single farms may occur for a variety of reasons ranging from humanitarian to pragmatic. Recognition may not be solicited if such gestures are designed to supplement existing law or correct difficult social problems in an environment of national political instability. Some landowners may react quite positively to highly localized problems to assure smoOlh functioning of agricultural systems where production is labor intensive. These …
