Climate Change And Nighttime Heat Stress: Tales Of Two Cities In The U.S. Midwest, Woonsup Choi

Geography Faculty Articles

This study explores nighttime heat stress in two Midwestern regions in the United States, encompassing the cities of Minneapolis and Milwaukee. Daily minimum temperature data were obtained from the MACAv2-METDATA dataset at a 4-km resolution. Data were downloaded both for the historical (1950- 2005) and RCP (Representative Concentration Pathways) 4.5 (2006-2099) simulations from 11 global climate models. MODIS land cover data at a 5'x5' resolution were used to delineate urban and non-urban areas. Heat stress was indicated by the occurrence of hot nights in two ways. First, the number of days with daily minimum temperatures above 300 K (27°C) was …

Using Drones To Generate New Data For Conservation Insights, Paul Lorah, Alice Ready, Emma Rinn

International Journal of Geospatial and Environmental Research

Human impact on the environment is driving a decline in biodiversity that heightens the need for informed management of conservation lands. Unmanned aerial vehicles (UAVs), also known as drones, are an increasingly cost-effective tool for generating high-quality data used to map landscape features, analyze land cover change and assess the effectiveness of conservation efforts. Traditional sources of remotely sensed data such as satellites and aircraft can be costly, inflexible and unable to detect fine-scale surface variation. This paper explores the advantages (and challenges) of analyzing data collected by drones to generate useful conservation management insights. We focus on three key …

The Invisible Crisis: Framing The Remediation Of Milwaukee's Lead Laterals, Isabella Rieke

Theses and Dissertations

When Milwaukee’s municipal water system was developed in 1874, one-half-inch lead pipes were used to convey water from the mains in the street to a customer’s home; the City has since acknowledged that nearly 100,000 such lead pipes are still in use today, a revelation which has opened for debate whether or not these pipes pose a galvanizing public health risk with far-reaching policy and infrastructure implications. This study explores the community response to Milwaukee’s lead laterals through the efforts of the Freshwater for Life Action Coalition (FLAC). How do Milwaukeeans understand the risks posed by the lead laterals? In …

The Tale Of Two Cities: A Feminist Critique Of Economic Development & Neoliberal Multiculturalism In Milwaukee, Yui Hashimoto

Theses and Dissertations

In this dissertation, I examine how race articulates with economic development in Milwaukee, Wisconsin. Drawing on two years of participant observation with the Milwaukee Fight for 15; participant observation of public meetings and days of action; semi-structured interviews with City officials, business leaders, non-profit professionals, and community organizers; and media and document analysis, I find that normative discourses of race underpin economic development in Milwaukee even as City officials and boosters give nominal recognition to racial inequality and purport to embrace diversity and colourblindness.

First, I trace historical and contemporary trajectories of economic development and segregation to show how the …

Uncertainty Assessment Of Spectral Mixture Analysis In Remote Sensing Imagery, Yingbin Deng

Theses and Dissertations

Spectral mixture analysis (SMA), a scheme of sub-pixel-based classifications, is one of the widely used models to map fractional land use and land cover information in remote sensing imagery. It assumes that: 1) a mixed pixel is composed by several pure land cover classes (endmembers) linearly or nonlinearly, and 2) the spectral signature of each endmember is a constant within the entire spatial extent of analysis. SMA has been commonly applied to impervious surface area extraction, vegetation fraction estimation, and land use and land cover change (LULC) mapping. Limitations of SMA, however, still exist. First, the existence of between- and …

Measured Expectations: An Examination Of Urban Agriculture Development And Operations In Milwaukee, Wi, Jamison Ellis

Theses and Dissertations

Urban agriculture has begun to shape urban spaces throughout the United States. Building from research on urban agriculture projects in Milwaukee I argue that in order for researchers to better understand urban agriculture, they must more thoroughly examine the various developmental and operational strategies that urban agriculture nonprofit organizations implement. The research questions that guides my thesis are the following: first, how do the developmental and operational strategies of urban agriculture projects differ? Second, how do different stakeholders perceive the implications of these approaches for creating positive and negative effects? To do this, I collected data through interviews and participant …

Critical Citizenship Education Through Geography, Jung Eun Hong

International Journal of Geospatial and Environmental Research

In a current globalized world, citizens are expected and encouraged to understand cultural diversity and respect individual differences. Furthermore, they are also expected to become responsible citizens for recognizing and actively participating in issues on social justice and human rights at local to global scales. That is, our diverse society demands “critical” citizens who are interested in public affairs, concerned about inequality and injustice, and motivated to change and improve our society. In response to an increased need for actively engaged and participating citizens in a today’s world, critical citizenship education has been suggested as a new framework for the …

Findings confirm that students taught by both paper and digital media showed improvement in spatial thinking skills …

Role Of Geography Courses In Improving Geospatial Thinking Of Undergraduates In The United States, Kanika Verma, Lawrence Estaville

International Journal of Geospatial and Environmental Research

This national study utilizes the Geospatial Thinking Survey (GTS) to assess the geospatial thinking abilities of undergraduates in the United States. A survey of 1479 students from 61 public universities provided the data. The mean score of geography majors was the highest, while that of criminal justice majors was the lowest. The mean score of students who studied at least three college geography courses was significantly higher than those students who took less than three college geography courses. College geography courses apparently bolster student geospatial thinking abilities, thereby corroborating the stronger geospatial thinking skills of geography majors. Moreover, individual questions …

Vegetation Land Cover/Use Dynamics And Their Effects In Mbulu And Karatu Districts In The North-Eastern Highlands Of Tanzania, Leonia John Raphael

International Journal of Geospatial and Environmental Research

Vegetation Land Cover/Land Use dynamics (VLC/LU) are the result of complex and compound interactions between the human (cultural, socioeconomic, and political) and the physical environment at different spatial scales. The present study assesses the spatial distribution of VLC/LU dynamics from 1987 to 2015 in the North-Eastern highlands of Tanzania using both qualitative (in-depth interviews and focus group discussions) and quantitative techniques (spatio-temporal analysis through GIS). The qualitative approach was used to elicit information on the main drivers of VLC/LU changes by land users as transitions occurred with time. The spatio-temporal analysis was used to assess the systematic vegetation land losses, …

Accuracy Evaluation Of The Canadian Openstreetmap Road Networks, Hongyu Zhang, Jacek Malczewski

International Journal of Geospatial and Environmental Research

Volunteered geographic information (VGI) has been applied in many fields such as participatory planning, humanitarian relief and crisis management. One of the reasons for popularity of VGI is its cost-effectiveness. However, the coverage and accuracy of VGI cannot be guaranteed. The issue of geospatial data quality in the OpenStreetMap (OSM) project has become a trending research topic because of the large size of the dataset and the multiple channels of data access. This paper focuses on a national study of the Canadian OSM road network data for the assessment of completeness, positional accuracy, attribute accuracy, semantic accuracy and lineage. The …

Examining Urban Heat Island Effect And Its Public Health Implications With Remotely Sensed Data, Yang Song

Theses and Dissertations

The Urban heat island (UHI) as a byproduct of urbanization has long been studied utilizing remote sensing technologies. However, issues remain to be addressed. Land surface temperature (LST) as the indicator of surface UHI can be retrieved from remotely sensed data, but its accuracy is limited as existing studies neglect the neighboring effect. Further, while LST serves well as an indicator of surface thermal condition, it lacks the ability to reveal human heat stress, which is an environmental hazard that can seriously affect productivity, health or even survival of individuals. Although human heat stress has long been studied and can …

Specifically, this study aimed to answer the following research questions: (1) What are the temporal trends of meteorological and streamflow droughts identified by drought indicators? (2) How do the drought indicators manifest drought propagation? Meteorological droughts were identified using the Effective Drought Index (EDI), and streamflow droughts were identified using a threshold-level approach. The intensity and duration of both types of drought were found to have decreased over …

Variation Of Groundwater Divides During Wet And Dry Years In The Wolf River Basin, Northeastern Wisconsin, Susan A. Borchardt

International Journal of Geospatial and Environmental Research

Groundwater divides and surface-water divides do not always coincide, and groundwater divides are not as easy to detect as surface-water divides. Groundwater divides are also dynamic, moving in response to environmental and anthropogenic stresses. This study will investigate how different hydrological stresses can change the size and shape of the study basin and whether the stresses together mitigate or intensify the basin’s response. This study looks at three factors that may affect the size and shape of the Wolf River basin: annual precipitation, soil permeability, and the presence of high-capacity wells. This study examined four groundwater basins that represent the …

Community Perspectives On Neighborhood Characteristics And Home-Buying Decisions, Madhuri Sharma

International Journal of Geospatial and Environmental Research

This paper analyzes households’ perceptions of neighborhoods according to Brown and Chung’s framework of Market-Led Pluralism (M-LP). Using household survey responses from 100 respondents in Columbus, Ohio and Milwaukee, Wisconsin, I empirically test MLP’s utility in understanding consumers’ decision making processes on where to live and who to live with. Consumers from all races/ethnicities ranked these attributes similarly, closely aligning with the M-LP. The quality of schools, safety of neighborhoods, price and affordability generally mattered to all consumers. However, African Americans’ perceptions of certain attributes as more valuable than others’ are likely due to their lower socio-economic status and the …

Validating Geospatial Regression Models With Bootstrapping, Lam T. Tran, Phoebe Tran

International Journal of Geospatial and Environmental Research

Spatial statistical models have been used extensively in many geospatial and environmental studies over several decades. While being very important, the issues of testing and validation in spatial statistical models are rarely investigated carefully in spatial environmental studies. Often strict theoretical asymptotic assumptions used in those models are left unexplored or unanswered in many studies. This study is to explore if bootstrapping is capable of providing more realistic statistical inference for spatial regression models while dealing with several common issues with spatial data, such as spatial dependence and unknown heteroscedasticity. With experiments on both simulated and real-world datasets, the study …

International Journal of Geospatial and Environmental Research

Vertical height estimates of earth surface features using an Unmanned Aerial System (UAS) are important in natural resource management quantitative assessments. An important research question concerns both the accuracy and precision of vertical height estimates acquired with a UAS and to determine if it is necessary to land a UAS between individual height measurements or if GPS derived height versus barometric pressure derived height while using a DJI Phantom 3 would affect height accuracy and precision. To examine this question, height along a telescopic height pole on the campus of Stephen F. Austin State University (SFASU) were estimated at 2, …

Effects Of Urban Imperviousness Scenarios On Simulated Storm Flow, Feng Pen, Woonsup Choi, Jinmu Choi

Geography Faculty Articles

The amount and distribution of impervious surfaces are important input parameters of hydrological models, especially in highly urbanized basins. This study tests three different methods to input impervious surface area information to a semi-distributed hydrological model in order to examine their effects on storm flow. The three methods being evaluated include: (1) a constant value for impervious surfaces in the entire urban area, (2) constant values of imperviousness for commercial and residential land uses, respectively, and (3) different imperviousness for the residential land use in each subbasin. Storm flow of the Milwaukee River Basin in southeastern Wisconsin (USA) was modeled …
