A New Method To Bridge New Materialism And Emotional Mapping: Spatio-Emotional Experiences In Disaster-Affected Brazilian Favelas, Gemma Sou, Juliana Carvalho, Natalia Cidade, Maria Eugenia

The Qualitative Report

Within the field of emotional mapping, and mapping more broadly, nonhuman things are often understood as mere instruments - they have utility but not agency to shape meaning-making. In this paper we experiment with a new method that aims to challenge the dualism between human and non-human things by bridging new materialism and participatory emotional mapping. We experimented with this “new materialist methodology” during a one-day workshop to explore residents’ spatio-emotional experiences in a disaster-affected favela in Rio de Janeiro, Brazil. Reflecting on this one-day workshop, we argue that materials with diverse colors, textures, shapes, densities, weights, and smells are …

Travel Agencies And Tourist Guides Adapting To Crisis: The Portuguese Case, Ilídia C. G. Carvalho

International Journal of Tour Guiding and Visitor Attraction Research

Tourism is constantly changing and new paradigms arise. Most recently, travel agencies and tourist guides have been facing difficulties and have had to quickly adapt themselves to be able to keep a position in the tourism market. COVID-19 brought major changes to travel and experience in destinations and it certainly increased the use of technology, which has totally changed communication systems and relationships in tourism. For this paper, interviews with Portuguese travel agents and tourist guides were carried out and were later analysed allowing the author to gain insights into the current situation regarding these two stakeholders, which were previously …

Smart City Tours As An Innovative Way To (Re)Discover Urban Environments In An Italian Context, Miriam L. Weiß

International Journal of Tour Guiding and Visitor Attraction Research

This article explores the foundations upon which to build innovation and further professionalise the tour guiding sector in an Italian context. It is based on a cooperation initiative started in March 2020 just at the beginning of the Covid-19 pandemic which proposes smart city tours as innovative, sustainable, and creative ways to (re)discover urban environments with the expected impact to make tour participants think, influence post-tour behaviour towards sustainability, and to provide a differentiated view of a visited place. The study is designed as a formative evaluation prior to introducing measures that allow further exploitation of the potential for smart …

Tour Guides And Access To Trails: Problems In The Baħrija Area Of Malta, David Pace

International Journal of Tour Guiding and Visitor Attraction Research

The Maltese islands barely cover an area of 300 square kilometres and yet, they enjoy a varied landscape characterised by cliffs, ridges, hills and valleys. There are over a hundred valleys on the main island of Malta and many provide important waterways during the rainy season and present some of the most beautiful and varied scenery. The most accessible include the Qlejgħa valley and White Poplar Valley (Wied il-Luq). Both are frequented by thousands of visitors, particularly during the weekends and are also quite popular with tourists during the winter months. Malta’s high population density, the influx of millions of …

Many humans live in large, complex political centers, composed of multi-scalar communities including neighborhoods and districts. Both today and in the past, neighborhoods form a fundamental part of cities and are defined by their spatial, architectural, and material elements. Neighborhoods existed in ancient centers of various scales, and multiple methods have been employed to identify ancient neighborhoods in archaeological contexts. However, the use of different methods for neighborhood identification within the same spatiotemporal setting results in challenges for comparisons within and between ancient societies. Here, we focus on using a single method—combining Average Nearest Neighbor (ANN) and Kernel Density (KD) …

Modeling Airport Catchment Areas: Using Spatial Analysis Approach, Sitong Chen

The Journal of Purdue Undergraduate Research

Th e airport catchment area is the geographic area from which an airport can reasonably expect to draw commercial air service passengers. Th e purpose of this interdisciplinary research is to estimate airport catchment areas using a spatial analysis method for informed airport management. In order to ensure the comprehensiveness and reliability of the research, we chose to analyze the catchment areas for five airports of different sizes and in different geographic locations in the United States. The Huff model, which is usually used in marketing, economics, and retail research, was adopted in this study. We applied this model in …

Who’S Cooking Tonight? A Time-Use Study Of Coupled Adults In Toronto, Canada, Bochu Liu, Michael J. Widener, Lindsey G. Smith, Steven Farber, Dionne Gesink, Leia M. Minaker, Zachary Patterson, Kristian Larsen, Jason Gilliland

Geography & Environment Publications

Understanding how coupled adults arrange food-related labor in relation to their daily time allocation is of great importance because different arrangements may have implications for diet-related health and gender equity. Studies from the time-use perspective argue that daily activities such as work, caregiving, and non-food-related housework can potentially compete for time with foodwork. However, studies in this regard are mostly centered on individual-level analyses. They fail to consider cohabiting partners’ time spent on foodwork and non-food-related activities, a factor that could be helpful in explaining how coupled partners decide to allocate time to food activities. Using 108 daily time-use logs …

National Forest Visitation Preferences And Avenues To Participation For Urban Hispanic Recreationists In The Portland Metropolitan Area (Usa), Lee Cerveny, Rebecca Mclain, David Banis, Matthew Helmer

Geography Faculty Publications and Presentations

Health benefits of outdoor recreation have been broadly demonstrated and land managers recognize the equity implications of providing safe and inclusive outdoor spaces. Data on public lands visitation and outdoor participation show that Hispanic recreationists are less likely to engage in outdoor leisure than White persons. Early studies of outdoor preferences of Hispanic persons identified a desire for large-group settings and social activities. To update our understanding of outdoor recreation needs, preferences, and constraints, we collaborated with a Latinx organization in Portland, Oregon (USA). We collaboratively designed three focus groups that combined structured engagement, cognitive sorting, and participatory mapping to …

Faculty Publications

The COVID-19 pandemic has exerted unprecedented impacts on the world. Since its onset, China has established a network of fever clinics as an effective strategy to aggressively isolate and screen possible patients with COVID-19 symptoms. This study presents two fever clinic maps that visualize the uneven responses to the COVID-19 pandemic at the city level in mainland China. The maps highlight more resources in the southwest, northwest, east, and south China, and paucity in the far west parts of southwest and northwest China and in the north and northeast China.

Multiscale Analysis Of Cancer Service Areas In The United States, Changzhen Wang, Tracy Onega, Fahui Wang

Faculty Publications

The purpose of delineating Cancer Service Areas (CSAs) is to define a reliable unit of analysis, more meaningful than geopolitical units such as states and counties, for examining geographic variations of the cancer care markets using geographic information systems (GIS). This study aims to provide a multiscale analysis of the U.S. cancer care markets based on the 2014–2015 Medicare claims of cancer-directed surgery, chemotherapy, and radiation. The CSAs are delineated by a scale-flexible network community detection algorithm automated in GIS so that the patient flows are maximized within CSAs and minimized between them. The multiscale CSAs include those comparable in …

Monitoring Asbestos Mine Remediation Using Airborne Hyperspectral Imaging System: A Case Study Of Jefferson Lake Mine, Us, Yongsik Jeong, Jaehyung Yu, Lei Wang, Huy Hoa Huynh, Hyun Cheol Kim

Faculty Publications

This study investigated an asbestos mine restoration project using Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) hyperspectral data. The distribution of an abandoned asbestos mine (AAM) and treatment area were analyzed before and after the remediation based on the spectral indices for detecting naturally occurring asbestos (NOA) indicators and encapsulation. The spectral indices were developed for NOA, host rock, and encapsulation by logistic regression models using spectral bands extracted from the random forest algorithm. The detection models mostly used VNIR spectra rather than SWIR and were statistically significant. The overall accuracy of the detection models was approximately 84%. Notably, the detection accuracy …

Modeling Vegetation Cover At Mount St Helens Using Highly Correlated Vegetation Indices, Sara Livingston

Geography and the Environment: Graduate Student Capstones

The eruption of Mount St. Helens in 1980 devastated the landscape and obliterated all ground vegetation within a 620 km2 blast zone radius. The destructive forces of the lateral blast, debris avalanche, tephra plume, and lahar flow created a complex mosaic of disturbance zones, that subsequently yielded various rates of landscape recovery. Remote sensing is an efficient method for monitoring landscape-scale changes by recording the distinct spectral reflectance of vegetation. Based on statistically significant correlations between Vegetation Indices and vegetation parameters, an empirical model can be developed for vegetation cover predictions. This capstone analysis found that NDVI holds the strongest …

Participatory Mapping To Address Neighborhood Level Data Deficiencies For Food Security Assessment In Southeastern Virginia, Usa, Nicole S. Hutton, George Mcleod, Thomas R. Allen, Christopher Davis, Alexander Garnand, Heather Richter, Prachi P. Chaven, Leslie Hoglund, Jill Comess, Matthew Herman, Brian Martin, Cynthia Romero

Political Science & Geography Faculty Publications

Background: Food is not equitably available. Deficiencies and generalizations limit national datasets, food security assessments, and interventions. Additional neighborhood level studies are needed to develop a scalable and transferable process to complement national and internationally comparative data sets with timely, granular, nuanced data. Participatory geographic information systems (PGIS) offer a means to address these issues by digitizing local knowledge.

Methods: The objectives of this study were two-fold: (i) identify granular locations missing from food source and risk datasets and (ii) examine the relation between the spatial, socio-economic, and agency contributors to food security. Twenty-nine subject matter experts from three cities …

Infrastructure's (Supra)Sacralizing Effects: Contesting Littoral Spaces Of Fishing, Faith, And Futurity Along Sri Lanka's Western Coastline, Orlando Woods

Research Collection School of Social Sciences

This paper explores the ways in which infrastructural development can cause the sacred to become a source of political legitimacy, and sacred authority to become a politically charged construct. For resource-dependent communities, the ecological damage caused by infrastructural development can cause ostensibly profane issues to be imbued with sacred meaning and value. With sacralization comes the expectation that figures of sacred authority will campaign for justice on behalf of the communities that they represent. However, when the authority evoked comes from outside the boundaries of institutionalized religion, processes of suprasacralization come into play. By exploring infrastructure’s (supra)sacralizing effects, I demonstrate …

Hydrological Drought Forecasting Using A Deep Transformer Model, Amobichukwu C. Amanambu, Joann Mossa, Yin-Hsuen Chen

University Administration Publications

Hydrological drought forecasting is essential for effective water resource management planning. Innovations in computer science and artificial intelligence (AI) have been incorporated into Earth science research domains to improve predictive performance for water resource planning and disaster management. Forecasting of future hydrological drought can assist with mitigation strategies for various stakeholders. This study uses the transformer deep learning model to forecast hydrological drought, with a benchmark comparison with the long short-term memory (LSTM) model. These models were applied to the Apalachicola River, Florida, with two gauging stations located at Chattahoochee and Blountstown. Daily stage-height data from the period 1928–2022 were …
