Dominant Role Of Grazing And Snow Cover Variability On Vegetation Shifts In The Drylands Of Kazakhstan, Venkatesh Kolluru, Ranjeet John, Jiquan Chen, Preethi Konkathi, Srinivas Kolluru, Sakshi Saraf, Geoffrey M. Henebry, Jingfeng Xiao, Khushboo Jain, Maira Kussainova

Faculty Publications

Decomposing the responses of ecosystem structure and function in drylands to changes in human-environmental forcing is a pressing challenge. Though trend detection studies are extensive, these studies often fail to attribute them to potential spatiotemporal drivers. Most attribution studies use a single empirical model or a causal graph that cannot be generalized or extrapolated to larger scales or account for spatial changes and multiple independent processes. Here, we proposed and tested a multi-stage, multi-model framework that detects vegetation trends and attributes them to ten independent social-environmental system (SES) drivers in Kazakhstan (KZ). The time series segmented residual trend analysis showed …

Global Urban Structural Growth Shows A Profound Shift From Spreading Out To Building Up, Steve Frolking, Richa Mahtta, Tom Milliman, Thomas Esch, Karen C. Seto

Faculty Publications

We present a new study examining the dynamics of global urban building growth rates over the past three decades. By combining datasets for 1,550+ cities from several space-borne sensors—data from three scatterometers and settlement-built fraction based on Landsat-derived data—we find profound shifts in how cities expanded from the 1990s to the 2010s. Cities had both increasing building fractional cover and increasing microwave backscatter (correlating with building volume), but over the three decades, growth rates in building fraction decreased in most regions and large cities, while growth rates in backscatter increased in essentially all regions and cities. The divergence in rates …

Geographic Links And Predictable Returns, Zuben Jin, Frank Weikai Li

Research Collection Lee Kong Chian School Of Business

Using establishment-level data of U.S. public firms, we construct a novel measure of geographic linkage between firms. We show that the returns of geography-linked firms have strong predictive power for focal firm returns and fundamentals. This effect is distinct from other cross-firm return predictability and is not easily attributable to risk-based explanations. It is more pronounced for focal firms that receive lower investor attention, are more costly to arbitrage, and during high sentiment periods. The cross-firm information spillovers and return predictability are also stronger for geographic peers with economic linkages and with positive information. Our results are broadly consistent with …

Schaeffer, Roswell Schaeffer, Sarah Betcher, Donna D W Hauser, Carson R. Witte, Jessica M. Lindsay, Ajit Subramaniam, Kate E. Turner, Alex Whiting

Faculty Publications

In polar regions, sea ice is a crucial mediator of the interaction between Earth's atmosphere and oceans. Its formation and breakup is intimately connected with large-scale climatic processes, local weather patterns, and the use of sea ice in coastal Arctic regions by Indigenous people. In order to investigate the physical phenomena at the heart of this process, a set of targeted, intensive observations were made over spring sea ice melt and breakup in Kotzebue Sound, Alaska. These observations were planned and executed through a collaborative effort in which an Indigenous Elder advisory council from Kotzebue and scientists participated in co-production …

An Overview Of Environmental Themes In The Video Game Industry, Michael A. Davis

The Geographical Bulletin

Video games of the early 1990s have an appreciable depth of environmental tones that seem prophetic by today’s standards as climate change and environmental degradation have emerged as significant topics of scientific and geographic inquiry. The political and cultural environment of the late 1980s and early 1990s played a significant role in the development of environmentally-minded video games. Since the 20th century, the depiction of these environmental themes have changed with a greater understanding of environmental science literature, have incorporated educational qualities to game play, and have migrated from large video game developers (e.g., Sega and Nintendo) to independent developers …

The terms “offshore” and “open ocean” have been used to describe aquaculture sites that are further from the coast or in higher energy environments. Neither term has been clearly defined in the scientific literature nor in a legal context, and the terms are often used interchangeably. These and other related terms (for example “exposed”, “high-energy”) variously refer to aspects of a site such as the geographic distance from shore or infrastructure, the level of exposure to large waves and strong currents, the geographic fetch, the water depth, or some combination of these parameters. The ICES Working Group (ICES, 2024) on …

Essays On The Application And Improvement Of The Geographical Economics Models To Policy Analysis: The Case Of Road Infrastructure In Central America, Ignacio Penagos

Economics Theses and Dissertations

The novel models of Geographical Economy have analyzed the effects on the distribution of economic activity over the area of a given region, generated by different socio-economic shocks. For example, the costs of migrating from one place to another, as shown in Desmet et al. (2018). A key advantage of such models is that, given the structural definition of the market interactions, they can first create counterfactual scenarios based on the economic fundamentals. And second, a broad set of variables can account for that impact. These dynamic spatial general equilibrium models embody features such as measures for amenities, trade and …

Texas Gothic, Taryn Uribe Turner

Art Theses and Dissertations

The emotional and the ecological combine to create my body of work titled, “Texas Gothic.” My thesis tells the stories of my oil paintings created through personal connections to a variety of landscapes, animals and experiences that share the setting of Texas.

Desire and regret take shape as animals and figures not fully formed or real. Unreliable narratives of the past are entangled with present tensions to create a painting that haunts and stalks.

And yet, there is hope!

Through nostalgia and sweetness and burdens, my paintings confront a shrouded future. The contradictions of time passing are explored in my …

Utilizing a voluntary survey with 187 participants across three urban watershed sites, the research aimed to analyze community perceptions concerning beavers and their impact on the environment, particularly in relation to their proximity to watercourses. Findings indicate that proximity significantly affects attitudes towards beavers, with those living closer to watercourses demonstrating more …

The Demotechnic Index Of Nations (1980 - 2018) And Its Correlation With The Human Development Index (1990 – 2021), Camden Rainwater

Graduate Theses and Dissertations

The Demotechnic Index (DI) and the Human Development Index (HDI) are both useful metrics for assessing the development of nations, with each providing unique insights about a country’s standard of living. The DI, which uses energy consumption as a gauge, excels in capturing the impact of conflicts and economic disruptions. Additionally, its ability to be calculated based on different energy sources allows for evaluation of a nation's progress towards sustainable consumption patterns. Conversely, the HDI combines healthcare, education, and income dimensions, and uses them as a proxy that highlights human health crises, educational improvements, and economic growth, albeit with less …

Direct Precipitation Of Siderite In Ferruginous Environments, A Grengs, G Ledesma, Y Xiong, S Katsev, S W. Poulton, E D. Swanner, C Wittkop

Faculty Publications

Siderite (FeCO 3 ) is often assumed to precipitate from dissimilatory reduction of Fe-(oxyhydr)oxides, but geochemical and mineralogical analyses from ferruginous (anoxic, Fe-rich) Canyon Lake, USA, suggest Fe-carbonate represents a direct early precipitate unrelated to substantial oxide burial.X-ray absorption near edge structure (XANES) spectroscopy of sediment trap materials and an anoxic sediment core indicated a mixture of Fe(II) and Fe(III) in water column particulates and ferruginous surface sediments, while all Mn phases were reduced.About 60 cm below the sediment-water interface, Fe-Mn carbonates were detected by X-ray diffraction and XANES, while Fe extended X-ray absorption fine structure (EXAFS) spectra were best …

Substance Abuse: The Symbolic Geography Of Hell In The Great Divorce, Richard A. Bergen

Mythlore: A Journal of J.R.R. Tolkien, C.S. Lewis, Charles Williams, and Mythopoeic Literature

Blake’s The Marriage of Heaven and Hell is a Romantic vision of evil energy that reaches to the heavens, a geographical representation of capacity and scope and perpetual cosmic change. On the other hand, Lewis’s vision of hell in The Great Divorce is that of a land without substance: a conurbation of addiction to mental maladies, an endless mental substance abuse, an emptying of presence, and a banal stasis to the journey of the soul. Many of Lewis’s sources and inspirations for The Great Divorce, similarly, portray hell as a land of paradoxical “seeming-largeness”, while having ontological smallness. Throughout …

Urban Farm, Not Toxic Harm: East Phillips Urban Farm And The Indigenous Right To The City, Oli Palmera Tierney

Tapestries: Interwoven voices of local and global identities

The East Phillips neighborhood in South Minneapolis has been planning to transform an abandoned warehouse into an indoor urban farm for nearly a decade. When the city of Minneapolis announced it would demolish the warehouse–releasing arsenic from the soil into the community–and use the land for a public works facility, a fierce battle over environmental justice and the right to produce space (a theory popularized by Henri Lefebvre) ensued. East Phillips is a geographically significant place: It has the largest urban concentration of Indigenous people in the country, and it is the birthplace of the American Indian Movement. Indigenous land …

The American View On Global Education In Curriculum And Its Necessity For Entering The Workforce, Alison Taylor

Student Theses and Dissertations

The problem addressed in this study is the lack of globalization terminology and geography standards included in the United States’ public education system leading to a workforce that is missing key 21st century skill competency. According to social efficiency theory, it is important for education to teach the necessary employability skills in the school curriculum. Geography standards align with employability skills, but the subject is disappearing from United States classrooms. This quantitative regression study evaluates the predictive relationships between exposure to geography curriculum in the United States, American perception of the importance of geography, and recent high school graduate’s self-assessed …
