The Climate Impact Of Tropical Peatland Degradation, René Dommain, Steve Frolking, Aurich Jeltsch-Thömmes, Fortunat Joos, John Couwenberg, Paul Glaser, Alexander Cobb, Charles Harvey

Faculty Publications

Southeast Asia is a global hotspot of peatland degradation and related greenhouse gas emissions. Anthropogenic impacts, mainly associated with agricultural conversion, shift Southeast Asian peatlands from carbon sinks to significant carbon sources. Here we first describe the impacts of anthropogenic drainage on landscape-scale carbon dynamics of individual peatlands and then use an impulse‐response model of radiative forcing to quantify the climate impacts of peat-carbon losses. Whereas water-table elevation (i.e. drainage depth) determines the magnitude of CO2 emissions at the site-scale, the geometric arrangement of artificial drainage networks determines carbon losses on the landscape-scale. Among all peatland greenhouse gas fluxes, the …

Faculty Publications

Cold-climate urban areas often face severe air pollution events in wintertime because of residential heating and vehicle emissions into shallow surface inversion layers. Many state-of-the-art regional chemistry-transport models cannot capture the small spatio-temporal scale of the transport and chemical processes occurring in these environments.Here we introduce a new version of our one-dimensional atmospheric chemistry and transport model, PACT-1D that includes continuous exchange of atmospheric air with the interstitial air of a snow layer and a kinetic treatment of multi-phase chemical processes in air and snow. PACT-1D allows modeling and assessment of the interaction of transport, chemistry, and emissions on the …

Air Quality Improvements Can Strengthen China's Food Security, Xiang Liu, Bowen Chu, Rong Tang, Yifan Liu, Xing Li, Jingfeng Xiao, Ankur Desai, Haikun Wang

Faculty Publications

China, with nearly 20% of the world's population, achieves self-sufficiency in major grain production using only about 10% of the global arable land. To further ensure food security in China, it is crucial to gain a deep understanding of the driving factors behind grain production. Climate change, water scarcity, and air pollution pose serious threats to food production. Air quality in China is among the poorest in the world, thus quantifying its impact on grain production not only holds significance for maintaining its food security but also provides valuable insights into future air quality management policies. Here, we conducted a …

Beyond Climate In Placencia, Belize: Navigating Environmental Change In The Anthropocene, Rory E. Mckenna

USF Tampa Graduate Theses and Dissertations

Examining opportunities for climate resilience requires an evaluation of lived experiences of environmental change which benefits from transdisciplinary perspectives. This research examines those experiences through the lens of anthropogenic change which allows for a critical focus on local conditions of environmental change specific to Placencia Village, Belize, over time. An anthropology of the anthropocene framing shifts the focus from the results of the global phenomenon responsible for climate change to the implications of local human-caused environmental change on natural systems, human-environment relationships and dynamics, and the future trajectories of these relationships. Through the use of interviews, go-alongs, participatory mapping, transdisciplinary …

Creating A Sense Of Place When Implementing A New Emergency Department In Denmark: A Qualitative Study, Jeanette Wassar Kirk, Per Nilsen, Ove Andersen, Nina Thórný Stefánsdóttir, Mette Bendtz Lindstrøm, Byron J Powell, Tine Tjørnhøj-Thomsen

2020-Current year OA Pubs

BACKGROUND: Physical locations play an essential yet often overlooked role in healthcare implementation processes. Implementation Science frameworks such as the Theoretical Domains Framework, the Consolidated Framework for Implementation Research, and the Implementation in Context framework acknowledge the importance of the physical environment, but they often treat it as a passive backdrop for change. However, from a cultural geographic perspective, spaces and places are dynamic, influencing behavior, social structures, and the acceptance of new practices. This study aims to explore how managers and emloyees develop a sense of place in a new emergency department (ED) and how these spatial dynamics influence …

The Stranger Society: The Case Of Economic And Social Development In The Tropics, Peter Murphy

Budhi: A Journal of Ideas and Culture

The economic and social prosperity of nations are usually attributed to functional requirements—such as honest government, effective transport and communication networks, health care and education—and development strategies such as investment in infrastructure. However, beyond a certain point peak economic and social success relies as much on human ingenuity as on capital investment. The article proposes that the world’s most prosperous societies have three recurring characteristics that foster such ingenuity: (1) they are all closely connected to trading portals, (2) they nourish paradoxical belief systems that underscore a proclivity for intellectual abstraction and pattern-based interaction, and (3) they are stranger societies …

Ritual Purification And Bathing: The Location And Function Of Siloam Pool And Solomon’S Pool In Second Temple Period Jerusalem, Nahshon Szanton

'Atiqot

Excavations at the southern tip of the ancient city of Jerusalem uncovered four pools from the Early Roman period: two, Silwan Pool and Birkat el-Ḥamra, within the city walls, and two smaller pools on the outskirts of the city. This paper provides archaeological data that supports the identification of Birkat el-Ḥamra with Solomon’s Pool and the Silwan Pool with the Siloam Pool, both of which are mentioned in contemporary historical sources. Furthermore, the function of the pools is discussed: the larger, Solomon’s Pool, seems to have been an open swimming pool, while the Siloam Pool was used for ceremonies and …

Scale-Dependent Effects Of Urban Canopy Cover, Canopy Volume, And Impervious Surfaces On Near-Surface Air Temperature In A Mid-Sized City, Carson Ralls, Anne Y. Polyakov, Vivek Shandas

Geography Faculty Publications and Presentations

Cities are significantly warmer than their surrounding rural environments. Known as the ‘urban heat island effect’, it can affect the health of urban residents and lead to increased energy use, public health impacts, and damage to infrastructure. Although this effect is extensively researched, less is known about how landscape characteristics within cities affect local temperature variation. This study examined how tree canopy cover, canopy volume, and impervious surface cover affect daytime near-surface air temperature, and how these effects vary between different scales of analysis (10, 30, 60, 90 m radii), ranging from approximate street corridor to city block size. Temperature …

Economic Foundations Of Contraceptive Transitions: Theories And A Review Of The Evidence, Mahesh Karra, Joshua Wilde

Urban Studies and Planning Faculty Publications and Presentations

We review the foundations of the economic development–contraception nexus, focusing on the pathways through which economic factors drive contraceptive adoption and change. We investigate the channels through which the relationship between economic development and contraceptive dynamics is mediated. Using global data, we document the correlations between economic development and contraception transitions over time and across geographies. We briefly examine the evidence of the role of fertility, both desired and realized, as a central pathway through which the relationship has been historically theorized and empirically verified. We also discuss a range of mechanisms through which economic development drives contraceptive use independently …

Paul Ricoeur's Anthropology Of Forgiveness, Guillermo R. Dionisio

Budhi: A Journal of Ideas and Culture

In his philosophical anthropology Paul Ricoeur sees man’s innate goodness, despite his propensity for evil, ramifying into many capacities, among them, forgiveness. The capacity to forgive, for Ricoeur, lies between the paralysis of the power to act due to human fault, and the possible lifting of this incapacity through the separation of the offending agent from his or her evil deeds. But if forgiveness obtains in isolating offenders from their evil deeds, their self-understanding, sense of responsibility, and identity might become distorted and inaccurate, and would make us question whether forgiveness should be horizontal, that is, conditional; or vertical, that …

Spatial Gap-Filling Of Himawari-8 Hourly Aod Products Using Machine Learning With Model-Based Aod And Meteorological Data: A Focus On The Korean Peninsula, Youjeong Youn, Seoyeon Kim, Seung Hee Kim, Yangwon Lee

Institute for ECHO Articles and Research

Given the complex spatiotemporal variability of aerosols, high-frequency satellite observations are essential for accurately mapping their distribution. However, optical remote sensing encounters difficulties in detecting Aerosol Optical Depth (AOD) over cloud-covered regions, creating data gaps that limit comprehensive environmental analysis. This study introduces a spatial gap-filling method for Himawari-8/Advanced Himawari Imager (AHI) hourly AOD data, using a Random Forest (RF) model that integrates meteorological variables and model-based AOD data. Developed and validated over South Korea from 1 January to 31 December 2019, the model effectively improved data coverage from 6% to 100%. The approach demonstrated high performance in blind tests, …

“It’S Essential We Learn How To Grow For Ourselves”: The Legacies Of Black Gardening In Racialized Food Systems., Funmi Odumosu

USF Tampa Graduate Theses and Dissertations

In this thesis, I aim to investigate the impact of food racism on Black communities, with a specific focus on the importance of gardening in combatting food apartheid and fostering holistic connections to nature and community in school-aged children. Inequitable access to major retail supermarkets and unequal distribution of healthy food options are intentionally occurring patterns in the food spaces of predominately Black communities. These food system inequities exacerbate a lack of consumption and potential consequences on the health and well-being of children of color particularly during critical physical and cognitive developmental periods.

Many solutions to these inequities entail implementing …

Between Autonomy And Automation: Mapping Practices Among Syrian Delivery Drivers In Beirut, Blake Atwood

Human-Machine Communication

This article studies the tension between autonomy and automation as it is experienced by Syrian refugee food-delivery drivers who work on the Toters app in Beirut, Lebanon. Central to this study are the freedom narratives these drivers construct, which reflect their ambivalent relationship with digital labor platforms. These narratives highlight how the algorithmic nature of the Toters app provides opportunities for self-employment and flexible work, crucial for refugees facing employment barriers and limited physical and social mobility in Lebanon. However, in these narratives, the drivers’ sense of autonomy is also often compromised by the app’s increasing automation, which imposes surveillance …

How Are We To Think About The Knowledge That We Should Know?, RaúL Fornet-Betancourt

Budhi: A Journal of Ideas and Culture

As a precondition of philosophical dialogue among different cultures, this essay forwards a series of questions regarding the epistemological presuppositions of the current dominant knowledge culture, which is characterized by a capitalistic, technological, and colonial ethos. By stating its presuppositions, situating these in the historical context of its development, and drawing their consequences, the essay opens up the possibility of overcoming this dominant ethos of knowledge through the recuperation of epistemological plurality by way of exchanges among a multiplicity of knowledge cultures. The essay proposes that it is philosophy’s task today to resist the dehumanization of knowledge by asking what …

Literature Engineering In West Visayas, Leoncio P. Deriada

Kritika Kultura

Language engineering involves the willful, studied—or even legislated—empowering of language to hasten its development. Literature, whose medium is language, can likewise be engineered. Certainly, an indicator of tremendous talent in the creation of contemporary literature and in nation building, the emergent writers of the region have sharpened their sense of locus just as they have succeeded in asserting their place in the nationhood of Philippine literature. Through generous funding and support, new writers have been developed and older writers invigorated. Thus, new writings have manifested themselves. For years, West Visayan writing had been only in Hiligaynon, the lingua franca, and …

Practitioners' Needs For Addressing The Challenges Of Sea-Level Rise—A Qualitative Assessment, D. Hirschfeld, K. M. Archie, E. Mateo, J. C. Arnott, J. A. Vano

Landscape Architecture and Environmental Planning Faculty Publications

Practitioners at the local and regional scale are under increased pressure to reduce risks to people and property posed by the threats of sea‐level rise (SLR) and associated impacts. To achieve this, a dialog between practitioners and scientists is imperative. Current research documents impacts of SLR, evaluates local SLR adaptation activities, identifies barriers to action, and works to assess local adaptive capacity. Despite this work, there has been little qualitative assessment of practitioners' needs when it comes to translating SLR science into local changes. To fill this gap, we used a combination of semi‐structured interviews and surveys. The interviews revealed …

Dendrochronological Dating Of The Duncan Tavern, Paris, Kentucky, Usa, Delaney Ballard, Maegen Rochner

The Cardinal Edge

Duncan Tavern is a historical structure located at 323 High Street in Paris, Kentucky in Bourbon County. The structure currently serves as the headquarters for the Kentucky Society of the Daughters of the American Revolution (KSDAR). KSDAR maintains that Duncan Tavern was originally built in the mid-1790s; the land was purchased in 1792 by Joseph Duncan, a civilian armorer in the Revolutionary War. Although Duncan Tavern has been listed on the National Register of Historical Places since 1973, a dendrochronological study of this structure was requested to quantitatively examine the legitimacy of archival and anecdotal claims about the construction history. …

Title: Comparing Climate Growth of Oak and Tulip Poplar Species in Bernheim Forest, Kentucky, USA using Dendrochronological Methods

Abstract:

With climate change, the state of Kentucky is expected to face increases in hydrological variability and extremes. To understand more about future projections, past climatic conditions can be analyzed with proxy-based data sources. Tree-rings provide annual to sub-annual resolution that can be used for proxy-based climate reconstructions. Kentucky, however, lacks tree-ring data and this leaves the state understudied from a high temporal and spatial resolution paleo perspective. …

Investigating Drought Response And Paleoclimate Potential Of A New Network Of White Oak Chronologies In Western Kentucky, Usa, Audrey J. Heichelbech, Megan Gibson, Maegen Rochner

The Cardinal Edge

In Kentucky, historic and paleo-climate data are limited, and current understanding of long-term climate change in the state relies on instrumental data spanning only 1895-present. Proxy data are necessary to extend the temporal and spatial span of climate information. One potential proxy source for Kentucky is tree ring data, but currently, only four such datasets are publicly available on the International Tree Ring Data Bank (ITRDB). Archaeological and archival timber sources may help to fill in this gap. In the 1940s, Florence Hawley-Ellis, the first woman dendrochronologist, collected samples of white oak (Quercus alba L.) from four counties in western …
