The Geopolitics Of Infrastructuralized Platforms: The Case Of Alibaba, Hong Shen, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

Contemporary digital platforms have become increasingly infrastructuralized, and started to raise geopolitical tensions with their global expansion. Amidst the heightened geopolitical competition between the US and China, the growing power of Chinese infrastructuralized platforms has made them the center of recent geopolitical dynamics. Drawing from an exploratory case study, this paper discusses Alibaba, one of the most prominent Chinese Internet giants, as an infrastructuralized platform, and highlights its geopolitical struggles. Often perceived as an e-commerce company, Alibaba has become ‘infrastructuralized’: its now-massive digital empire has moved beyond e-commerce, expanding into almost every aspect of China’s and global digital economy such …

The Law Of Scale Independence, Jonathan D. Phillips

Geography Faculty Publications

Geography and geosciences deal with phenomena that span spatial scales from the molecular to the planetary, and temporal scales from instantaneous to billions of years. A strong reductionist tradition in geosciences and spatial sciences tempts us to seek to apply similar representations and process-based explanations across these vast-scale ranges, usually from a bottom-up perspective. However, the law of scale independence (LSI) states that for any phenomenon that exists across a sufficiently large range of scales, there exists a scale separation distance at which the scales are independent with respect to system dynamics and explanation. The LSI is evaluated here from …

A Global Survey Of Infection Control And Mitigation Measures For Combating The Transmission Of Covid-19 Pandemic In Buildings Under Facilities Management Services, Hadi Sarvari, Zhen Chen, Daniel W. M. Chan, Ellyn A. Lester, Nordin Yahaya, Hala Nassereddine, Aynaz Lotfata

Civil Engineering Faculty Publications

Facilities management along with health care are two important aspects in controlling the spread of infectious diseases with regard to controlling the outbreak of global COVID-19 pandemic. Hence, with the increasing outbreak of COVID-19 pandemic, the importance of examining the relationship between the built environment and the outbreak of infectious diseases has become more significant. The aim of the research described in this article is to develop effective infection control and mitigation measures to prevent the transmission of COVID-19 pandemic in the built environment. This study seeks to answer the question of how the facilities management industry can help reduce …

Futurological Fodder: On Communicating The Relationship Between Artificial Intelligence, Robotics, And Employment, Michael E. Samers Dr

Geography Faculty Publications

This article examines the debate concerning the employment implications of the so-called ‘Fourth Industrial Revolution’ (FIR) or the increasing presence of artificial intelligence and robotics in workplaces. I analyze three ‘genres’ associated with this debate (academic studies including neo-classical and heterodox/post-human approaches, the ‘gray literature’, and popular media) and I argue that together they represent ‘futurological fodder’ or discourses and knowledges that ‘perform’ the FIR and its purported consequences. I contend further that these genres involve a complex mix of ethics and politics, and I conclude with a reflection on the political implications of the FIR debate.

“We Just Need The Developer To Develop”: Entrepreneurialism, Financialization And Urban Redevelopment In Lexington, Kentucky, Kevin Ward, Andrew Wood

Geography Faculty Publications

Since the 1980s US city governments have increased their use of more speculative means of financing economic redevelopment. This has involved experimenting with a variety of financial and taxation instruments as a way of growing their economies and redeveloping their built environments. This very general tendency, of course, masks how some cities have done well through the use of these instruments while others have not. The work to date has tended to pivot around a “winner-loser dichotomy”, which emphasises either the capacity of US cities to be able to experiment and speculate through the use of one financial instrument or …

Trends In Land Surface Phenology Across The Conterminous United States (1982-2016) Analyzed By Neon Domains, Liang Liang, Geoffrey M. Henebry, Lingling Liu, Xiaoyang Zhang, Li-Chih Hsu

Geography Faculty Publications

Tracking phenological change in a regionally explicit context is a key to understanding ecosystem status and change. The current study investigated long-term trends of satellite-observed land surface phenology (LSP) in the 17 National Ecological Observatory Network (NEON) domains across the conterminous United States (CONUS). Characterization of LSP trends was based on a high temporal resolution (3-d) time series of the two-band enhanced vegetation index (EVI2) derived from a long-term data record (LTDR) of the Advanced Very High Resolution Radiometer (AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS). We identified significant trend patterns in LSP and their seasonal climate and land …

Creating A Field-Wide Forage Canopy Model Using Uavs And Photogrammetry Processing, Cameron Minch, Joseph S. Dvorak, Joshua J. Jackson, Stuart Tucker Sheffield

Biosystems and Agricultural Engineering Faculty Publications

Alfalfa canopy structure reveals useful information for managing this forage crop, but manual measurements are impractical at field-scale. Photogrammetry processing with images from Unmanned Aerial Vehicles (UAVs) can create a field-wide three-dimensional model of the crop canopy. The goal of this study was to determine the appropriate flight parameters for the UAV that would enable reliable generation of canopy models at all stages of alfalfa growth. Flights were conducted over two separate fields on four different dates using three different flight parameters. This provided a total of 24 flights. The flight parameters considered were the following: 30 m altitude with …

Mapping Complex Land Use Histories And Urban Renewal Using Ground Penetrating Radar: A Case Study From Fort Stanwix, Tyler Stumpf, Daniel P. Bigman, Dominic J. Day

Anthropology Graduate Research

Fort Stanwix National Monument, located in Rome, NY, is a historic park with a complex use history dating back to the early Colonial period and through the urban expansion and recent economic revitalization of the City of Rome. The goal of this study was to conduct a GPR investigation over an area approximately 1 acre in size to identify buried historic features (particularly buildings) so park management can preserve these resources and develop appropriate educational programming and management plans. The GPR recorded reflection events consistent with our expectations of historic structures. Differences in size, shape, orientation, and depth suggest that …

Detecting Recent Crop Phenology Dynamics In Corn And Soybean Cropping Systems Of Kentucky, Yanjun Yang, Bo Tao, Liang Liang, Yawen Huang, Christopher J. Matocha, Chad D. Lee, Michael Sama, Bassil El Masri, Wei Ren

Geography Faculty Publications

Accurate phenological information is essential for monitoring crop development, predicting crop yield, and enhancing resilience to cope with climate change. This study employed a curve-change-based dynamic threshold approach on NDVI (Normalized Differential Vegetation Index) time series to detect the planting and harvesting dates for corn and soybean in Kentucky, a typical climatic transition zone, from 2000 to 2018. We compared satellite-based estimates with ground observations and performed trend analyses of crop phenological stages over the study period to analyze their relationships with climate change and crop yields. Our results showed that corn and soybean planting dates were delayed by 0.01 …

Undoing Mastery: With Ambivalence?, Jess Linz, Anna J. Secor

Geography Graduate Research

In this commentary, we respond to Derek Ruez and Daniel Cockayne’s article ‘Feeling Otherwise: Ambivalent Affects and the Politics of Critique in Geography’. We do so by picking up ambivalence—or more precisely, ambivalence about ambivalence—as a tool with which Ruez and Cockayne leave us. We find this tool somewhat difficult to grasp, but we understand this as part of its design. Ambivalence undoes the subject’s mastery. In doing so, we find that an airing of ambivalence gives other kinds of entangled, indeterminate, and unknowing relations room to breathe.

Challenges When Identifying Migration From Geo-Located Twitter Data, Caitrin Armstrong, Ate Poorthuis, Matthew Zook, Derek Ruths, Thomas Soehl

Geography Faculty Publications

Given the challenges in collecting up-to-date, comparable data on migrant populations the potential of digital trace data to study migration and migrants has sparked considerable interest among researchers and policy makers. In this paper we assess the reliability of one such data source that is heavily used within the research community: geolocated tweets. We assess strategies used in previous work to identify migrants based on their geolocation histories. We apply these approaches to infer the travel history of a set of Twitter users who regularly posted geolocated tweets between July 2012 and June 2015. In a second step we hand-code …

Viral Data, Agnieszka Leszczynski, Matthew Zook

Geography Faculty Publications

We are experiencing a historical moment characterized by unprecedented conditions of virality: a viral pandemic, the viral diffusion of misinformation and conspiracy theories, the viral momentum of ongoing Hong Kong protests, and the viral spread of #BlackLivesMatter demonstrations and related efforts to defund policing. These co-articulations of crises, traumas, and virality both implicate and are implicated by big data practices occurring in a present that is pervasively mediated by data materialities, deeply rooted dataist ideologies that entrench processes of datafication as granting objective access to truth and attendant practices of tracking, data analytics, algorithmic prediction, and data-driven targeting of individuals …

Predicting And Mapping Plethodontid Salamander Abundance Using Lidar-Derived Terrain And Vegetation Characteristics, Marco Antonio Contreras, Wesley A. Staats, Steve J. Price

Forestry and Natural Resources Faculty Publications

Aim of the study: Use LiDAR-derived vegetation and terrain characteristics to develop abundance and occupancy predictions for two terrestrial salamander species, Plethodon glutinosus and P. kentucki, and map abundance to identify vegetation and terrain characteristics affecting their distribution.

Area of study: The 1,550-ha Clemons Fork watershed, part of the University of Kentucky’s Robinson Forest in southeastern Kentucky, USA.

Materials and methods: We quantified the abundance of salamanders using 45 field transects, which were visited three times, placed across varying soil moisture and canopy cover conditions. We created several LiDAR-derived vegetation and terrain layers and used these …

Towards An Economic Geography Of Fintech, Karen P. Y. Lai, Michael Samers

Geography Faculty Publications

In this paper, we identify the ways in which the existing literature has examined financial technology (FinTech). Using the frame of the ‘FinTech Cube’, we examine how FinTech unfolds through the intersections of key actors, technologies and institutions. We demonstrate the relevance of FinTech for two areas of geographical enquiry: i) the reshaping of global production and financial networks, and ii) financial inclusion and poverty reduction in poorer countries. In doing so, we accord particular attention to the significance of FinTech for theoretical and empirical research in economic geography.

Covid-19 Is Spatial: Ensuring That Mobile Big Data Is Used For Social Good, Age Poom, Olle Järv, Matthew Zook, Tuuli Toivonen

Geography Faculty Publications

The mobility restrictions related to COVID-19 pandemic have resulted in the biggest disruption to individual mobilities in modern times. The crisis is clearly spatial in nature, and examining the geographical aspect is important in understanding the broad implications of the pandemic. The avalanche of mobile Big Data makes it possible to study the spatial effects of the crisis with spatiotemporal detail at the national and global scales. However, the current crisis also highlights serious limitations in the readiness to take the advantage of mobile Big Data for social good, both within and beyond the interests of health sector. We propose …

A Visual Typology Of Abandonment In Rural America: From End-Of-Life To Treading Water, Recycling, Renaissance, And Revival, Jason P. Holcomb, Paul Frederic, Stanley D. Brunn

Geography Faculty Publications

The contemporary American rural landscape reflects a mix of ongoing economic changes in agricultural land use, population change, and built environments. The mix depends on past and recent change which represent landscapes of memory and silence to those experiencing economic and demographic renaissance. We develop a typology of five stages that reflect the contemporary rural scene and conduct field transects in Northwest Iowa and Central Maine. Features of the dynamics in rural America are evident in photographs of residences, land use changes, and commercial structure. The study calls for additional studies on rural settlement populations, economies, and society in different …

Global Pattern And Change Of Cropland Soil Organic Carbon During 1901-2010: Roles Of Climate, Atmospheric Chemistry, Land Use And Management, Wei Ren, Kamaljit Banger, Bo Tao, Jia Yang, Yawen Huang, Hanqin Tian

Plant and Soil Sciences Faculty Publications

Soil organic carbon (SOC) in croplands is a key property of soil quality for ensuring food security and agricultural sustainability, and also plays a central role in the global carbon (C) budget. When managed sustainably, soils may play a critical role in mitigating climate change by sequestering C and decreasing greenhouse gas emissions into the atmosphere. However, the magnitude and spatio-temporal patterns of global cropland SOC are far from well constrained due to high land surface heterogeneity, complicated mechanisms, and multiple influencing factors. Here, we use a process-based agroecosystem model (DLEM-Ag) in combination with diverse spatially-explicit gridded environmental data to …

Attentional Social Media: Mapping The Spaces And Networks Of The Fashion Industry, Ate Poorthuis, Dominic Powers, Matthew Zook

Geography Faculty Publications

In this article we use big data methods to analyze the attention paid to the fashion industry on social media. The article argues that for the fashion industry, like many industries, the core product is a form of knowledge that is dependent on gaining and holding people’s attention. To understand this attentional economy, social media offers a unique window because it is increasingly a central space within which fashion knowledge is created and shared. Using long-term, geotagged big data from Twitter, we analyze the hitherto difficult-to-explore spaces and places of the global fashion industry. The article suggests that the data …

Geographic And Climatic Attributions Of Autumn Land Surface Phenology Spatial Patterns In The Temperate Deciduous Broadleaf Forest Of China, Weiguang Lang, Xiaoqiu Chen, Liang Liang, Shilong Ren, Siwei Qian

Geography Faculty Publications

Autumn vegetation phenology plays a critical role in identifying the end of the growing season and its response to climate change. Using the six vegetation indices retrieved from moderate resolution imaging spectroradiometer data, we extracted an end date of the growing season (EOS) in the temperate deciduous broadleaf forest (TDBF) area of China. Then, we validated EOS with the ground-observed leaf fall date (LF) of dominant tree species at 27 sites and selected the best vegetation index. Moreover, we analyzed the spatial pattern of EOS based on the best vegetation index and its dependency on geo-location indicators and seasonal temperature/precipitation. …

Bittencourt-Silva, María Torres-Sánchez, Mark Wilkinson, Jeffrey W. Streicher, Simon T. Maddock, Ramachandran Kotharambath, Hendrik Müller, Francesca Nicole Angiolani Larrera, Diego Amieda-Reinoso, Santiago R. Ron, Diego Francisco Cisneros-Heredia

Neuroscience Faculty Publications

Since 1984 there have been no records of Rhaebo colomai (Hoogmoed, 1985) within the territory of Ecuador. This species was known from 2 localities in the province of Carchi, northwestern Ecuador, and the department of Nariño, southwestern Colombia, which were reported in 1979 and 2015, respectively. We report the recent sightings of R. colomai at 3 new localities in Ecuador and discuss and evaluate this species’ extinction risk and conservation status.

The Digital Knowledge Economy Index: Mapping Content Production, Sanna Ojanperä, Mark Graham, Matthew Zook

Geography Faculty Publications

We propose the construction of a Digital Knowledge Economy Index, quantified by way of measuring content creation and participation through digital platforms, namely the code sharing platform GitHub, the crowdsourced encyclopaedia Wikipedia, and Internet domain registrations and estimating a fifth sub-index for the World Bank Knowledge Economy Index for year 2012. This approach complements conventional data sources such as national statistics and expert surveys and helps reflect the underlying digital content creation, capacities, and skills of the population. An index that combines traditional and novel data sources can provide a more revealing view of the status of the world’s digital …

Hacking Code/Space: Confounding The Code Of Global Capitalism, Matthew Zook, Mark Graham

Geography Faculty Publications

Information-technologies are essential for global capitalism to function at speed across scale, space and complexity. The importance of software and algorithms in the governance of these systems is reflected in the attention of scholars to the ways digital code and materiality (re)combine to create hybrid digital/material spaces of economic activity, movement and everyday life. This paper extends this work in two key ways: first by emphasising the relational aspect of these code/spaces, and second by showing how the digital algorithms of code/spaces are hackable rather than hegemonic. Using the case study of frequent flyer programmes we demonstrate how networked knowledge-sharing …

Spatial Distribution Of Partner-Seeking Men Who Have Sex With Men Using Geosocial Networking Apps: Epidemiologic Study, Angel B. Algarin, Patrick J. Ward, W. Jay Christian, Abby E. Rudolph, Ian W. Holloway, April M. Young

Epidemiology and Environmental Health Faculty Publications

Background: Geosocial networking apps have made sexual partner-seeking easier for men who have sex with men, raising both challenges and opportunities for human immunodeficiency virus and sexually transmitted infection prevention and research. Most studies on men who have sex with men geosocial networking app use have been conducted in large urban areas, despite research indicating similar patterns of online- and app-based sex-seeking among men who have sex with men in rural and midsize cities.

Objective: The goal of our research was to examine the spatial distribution of geosocial networking app usage and characterize areas with increasing numbers of partner-seeking men …

Predicting Potential Fire Severity Using Vegetation, Topography And Surface Moisture Availability In A Eurasian Boreal Forest Landscape, Lei Fang, Jian Yang, Megan White, Zhihua Liu

Forestry and Natural Resources Faculty Publications

Severity of wildfires is a critical component of the fire regime and plays an important role in determining forest ecosystem response to fire disturbance. Predicting spatial distribution of potential fire severity can be valuable in guiding fire and fuel management planning. Spatial controls on fire severity patterns have attracted growing interest, but few studies have attempted to predict potential fire severity in fire-prone Eurasian boreal forests. Furthermore, the influences of fire weather variation on spatial heterogeneity of fire severity remain poorly understood at fine scales. We assessed the relative importance and influence of pre-fire vegetation, topography, and surface moisture availability …

Language And Socioeconomics Predict Geographic Variation In Peer Review Outcomes At An Ecology Journal, C. Sean Burns, Charles W. Fox

Information Science Faculty Publications

Papers submitted by scientists located in western nations generally fare better in the peer review process than do papers submitted by scientists from elsewhere. This paper examines geographic variation in peer review outcomes (whether a manuscript is sent for review, review scores obtained, and final decisions by editors) for 3529 submissions over a 4.5 year period at the journal Functional Ecology. In particular, we test whether geographic variation in language and socioeconomics are adequate to explain most or are all of this variation. There was no relationship between the geographic regions of handling editors and the decisions to send …

Nonmeteorological Influences On Severe Thunderstorm Warning Issuance: A Geographically Weighted Regression-Based Analysis Of County Warning Area Boundaries, Land Cover, And Demographic Variables, Megan L. White, J. Anthony Stallins

Geography Faculty Publications

Studies have shown that the spatial distribution of severe thunderstorm warnings demonstrates variation beyond what can be attributed to weather and climate alone. Investigating spatial patterns of these variations can provide insight into nonmeteorological factors that might lead forecasters to issue warnings. Geographically weighted regression was performed on a set of demographic and land cover descriptors to ascertain their relationships with National Weather Service (NWS) severe thunderstorm warning polygons issued by 36 NWS forecast offices in the central and southeastern United States from 2008 to 2015. County warning area (CWA) boundaries and cities were predominant sources of variability in warning …

Crowd-Sourcing The Smart City: Using Big Geosocial Media Metrics In Urban Governance, Matthew Zook

Geography Faculty Publications

Using Big Data to better understand urban questions is an exciting field with challenging methodological and theoretical problems. It is also, however, potentially troubling when Big Data (particularly derived from social media) is applied uncritically to urban governance via the ideas and practices of “smart cities”. This essay reviews both the historical depth of central ideas within smart city governance —particular the idea that enough data/information/knowledge can solve society problems—but also the ways that the most recent version differs. Namely, that the motivations and ideological underpinning behind the goal of urban betterment is largely driven by technology advocates and neoliberalism …

The Urban Geographical Imagination In The Age Of Big Data, John Taylor Shelton

Geography Faculty Publications

This paper explores the variety of ways that emerging sources of (big) data are being used to re-conceptualize the city, and how these understandings of what the urban is shapes the design of interventions into it. Drawing on work on the performativity of economics, this paper uses two vignettes of the ‘new urban science’ and municipal vacant property mapping in order to argue that the mobilization of Big Data in the urban context doesn’t necessarily produce a single, greater understanding of the city as it actually is, but rather a highly variegated series of essentialized understandings of the city that …
