Department of Anthropology Faculty Scholarship and Creative Works

The loss and degradation of forests and other ecosystems worldwide threaten both global biodiversity and the livelihoods of people who use natural resources. Understanding how natural resource use impacts landscape provisioning services for both people and wildlife is thus critical for designing comprehensive resource management strategies. We used data from community focus groups, botanical plots and an inventory of plant species consumed by the Critically Endangered red-ruffed lemur (Varecia rubra) to assess the availability of key provisioning services for people and endemic wildlife on the Masoala Peninsula, a rainforest transformation landscape, in northeastern Madagascar (Masoala National Park and 13 surrounding …

The Challenges Of The Increasing Institutionalization Of Climate Security, Judith N. Hardt, Dhanasree Jayaram, Cameron Harrington, Duncan Mclaren

Open Access archive

A rapid and widespread institutionalization of climate security is underway, led by powerful states and international organizations. Recognition of the climate crisis by security actors as a serious threat to humanity is long overdue, but it is imperative that this institutionalization is critically scrutinized. This commentary highlights specific dangers that accompany the institutional mainstreaming of climate security, including a non-reflexive integration into traditional security paradigms, a growing geopolitical separation between discourses emerging from the Global South and North, and policymaking that tends to draw from a narrow view of the science. Science-based and actionable research informed by pluralistic understandings of …

The Effects Of Land Use Change On Ant Communities In New England, Amelia K.L. Curry, Joseph A. Nelsen, Dale R. Stevens, Kaitlyn A. Mathis

Biology

Urbanisation and agricultural expansion are two of the most prevalent and intense forms of land use change worldwide and can have dramatic consequences on biodiversity and biotic community structure. Ants are extremely widespread, ecologically diverse and small ectotherms that are sensitive to changes from a wide range of environmental factors. Therefore, ants make an ideal study organism to examine the effects of anthropogenic land use change on biotic communities. In this study, we examined differences in ant species richness and community composition between urban parks, farms and forest fragments, and related these differences to environmental factors that vary among each …

Procedures For Rangeland Condition Assessment In The Pilbara And Southern Rangelands 2022, Department Of Primary Industries And Regional Development

Natural resources published reports

To define the procedures used in 2022 by DPIRD to complete rangeland condition assessment (RCA) in the Pilbara and southern rangelands region which has predominantly shrub-based pastures. For the rest of the pastoral estate, DPIRD uses the Procedures for RCA in the Kimberley which has grass pastures.

RCA is the process DPIRD uses to make systematic, lease level assessment of rangeland. Rangeland condition considers both the condition of pastures (as defined in the Pasture condition and management guide for the Pilbara rangelands or Southern rangelands pasture condition and management guides) and soils (as determined by erosion, using the erosion assessment …

On Fire And Water: The Intersection Of Wetlands And Burning Strategies In Managing The Anthropogenic Plant Communities Of Yosemite National Park, Douglas Deur, Rochelle Bloom

Anthropology Faculty Publications and Presentations

The existing literature confirms that Native American tribes historically enhanced culturally preferred plant communities through periodic burning in what is today Yosemite National Park; in turn, beginning with nineteenth-century park development, fire suppression contributed to conifer and shrub encroachment on anthropogenic meadows and other culturally significant habitats. However, we contend that traditional burning practices cannot be understood without considering the pronounced cultural role of wetland habitats and species, and the intersection between burning practices and wetland plant communities among tribes of the Sierra Nevada Range. Our ethnographic investigations revealed that a majority of culturally important plants identified by tribal members …

The Evolution Of Agrarian Landscapes In The Tropical Andes, Courtney Shadik, Mark B. Bush, Bryan G. Valencia, Angela Rozas-Davila, Daniel Plekhov, Robert D. Breininger, Multiple Additional Authors

Anthropology Faculty Publications and Presentations

Changes in land-use practices have been a central element of human adaptation to Holocene climate change. Many practices that result in the short-term stabilization of socio-natural systems, however, have longer-term, unanticipated consequences that present cascading challenges for human subsistence strategies and opportunities for subsequent adaptations. Investigating complex sequences of interaction between climate change and human land-use in the past—rather than short-term causes and effects—is therefore essential for understanding processes of adaptation and change, but this approach has been stymied by a lack of suitably-scaled paleoecological data. Through a highresolution paleoecological analysis, we provide a 7000-year history of changing climate and …

Novel Methods For Modeling And Treating Biofilm Infections, Emily Lazarus

Theses

Biofilms are responsible for the development of chronic infections, which are 10-1000 times more resistant to antimicrobial agents than two-dimensional (2D) planktonic culture. Traditionally, 2D planktonic cultures are used to study efficacy of antimicrobial treatments but 2D cultures have several shortcomings such as increased sensitivity to treatments, lack of complexity of the three-dimensional (3D) environment, limited host defense mechanisms, and lack the structural thickness of natural biofilms. Biofilm-related infections play a critical role in the delayed healing process of chronic skin wounds, and while treatments for chronic skin wounds exist, including negative pressure wound healing (NPWT), biofilm infections still prevail. …

Improving Adaptation Of Deep Learning With Inductive Bias, Xiajun Jiang

Theses

Human intelligence is strong at adapting to a small number of observations, partially because of the human ability to 1) use given knowledge and 2) distill knowledge from related but different data to guide learning for future tasks, where such ability is the inductive bias during learning. Deep learning shows a promising solution to artificial intelligence. However, generalizing or adapting deep learning models to heterogeneous tasks remains an open question. Existing data-driven models often ignore prior knowledge about the underlying problems of interest, or have limitations in incorporating complex knowledge into neural networks. The one-size-fit-all formula assumes the training and …

Hierarchical Parameterization In Spherical Domains For Deforming Feature Alignment, Lizhou Cao

Theses

The growing interest in immersive technology and lifelike virtual worlds has underscored the importance of creating automated methods to generate characters with a wide range of morphological variations. Traditional methods have either depended heavily on manual effort or simplified the challenge by only addressing static meshes or basic deformation transfers, without supporting dynamic shape morphing with deformation. In this work, we introduce a novel method that leverages cross-parameterization to semi-automate the creation of characters that are not only morphologically varied but also capable of synthesized deformation and animations. The key innovation of our work lies in the parameterization of deforming …

What Can We Learn About Teaching Excellence From Our Students? Lessons From Six Years Of Teaching Award Data, Christopher Shortell, Kris Henning, Carl Christiansen

Criminology and Criminal Justice Faculty Publications and Presentations

Teaching excellence in higher education can be defined and studied in different ways, but research efforts to date have often focused on institutional or instructor perspectives. This article uses a data set of over 500 open-ended comments submitted by Political Science undergraduates as part of a teaching award process to identify themes that matter most to students. We find that being supportive, bringing humor, enthusiasm, and passion to the classroom, and engaging students with relevant, challenging, and exciting activities are what defines teaching excellence from a student’s perspective. Building on these themes and using quotes to illustrate key concepts, we …

Exasperated But Not Exhausted: Unlocking The Trap Set By The Exhaustion Doctrine On The Fda’S Rems Petitioners, Michael Krupka

Vanderbilt Law Review

When health is at stake, bureaucratic delays can be disastrous. This is especially true in the field of pharmaceutical regulation. Fortunately, concerned parties—ranging from research institutions and universities to doctors and pharmaceutical companies—can file citizen petitions to urge the Food and Drug Administration (“FDA”) to regulate potentially risky drugs through Risk Evaluation and Mitigation Strategies (“REMS”) programs. But despite submitting comprehensive citizen petitions calling for changes to REMS determinations, petitioners regularly await the FDA’s response for years. When these petitioners, still awaiting an FDA determination, have sought recourse in the courts, the agency has argued that these petitioners have not …

Parallelized Quadtrees For Image Compression In Cuda And Mpi, Aidan Jones

Senior Honors Theses

Quadtrees are a data structure that lend themselves well to image compression due to their ability to recursively decompose 2-dimensional space. Image compression algorithms that use quadtrees should be simple to parallelize; however, current image compression algorithms that use quadtrees rarely use parallel algorithms. An existing program to compress images using quadtrees was upgraded to use GPU acceleration with CUDA but experienced an average slowdown by a factor of 18 to 42. Another parallelization attempt utilized MPI to process contiguous chunks of an image in parallel and experienced an average speedup by a factor of 1.5 to 3.7 compared to …

Spiritual Fathering: Does It Really Make A Difference?, Jeffrey A. Jacob

Doctor of Ministry (DMin)

The importance and impact of having a father in the home is undisputable. Statistics dictate that the effect of fatherlessness on children is devastating. Could it be that having a spiritual father or mother involved in a believer’s life makes a verifiable difference as well? This dissertation will investigate the effects of spiritual fathering as evidenced by the spiritual disciplines of those who identify as having a strong spiritual father or mother. The Apostle Paul said, “Even if you had ten thousand guardians in Christ, you do not have many fathers, for in Christ Jesus I became your father through …

The Great Cultural Commission: Fulfilling The Command Of Jesus To Lead And Create A Culture Different Than The World’S, Kevin D. Geer

Doctor of Ministry (DMin)

Jesus gathered his disciples together and shared with them how the leaders of this world love to use their influence, power, and titles to rule over those they lead. Jesus told his disciples “among you it will be different” (Matt 20:26) compared to the leadership of the world. Jesus called his disciples to the Great Culture Commission, a call to servant leadership in which one uses their opportunities, gifts, and advantages to lift everyone else around them. This call creates a culture that propels the Great Commission while cultivating servant-hearted leadership. The intent of this dissertation is to discover the …

This project aims to tackle the issue of discipleship and formation by exploring the development and application of a practical, spirit-led model of spiritual formation for the 21st-century North American Church. By drawing on the rich traditions of monastic, mystical, and sacramental spirituality, this project seeks to create a Pentecostal model of spiritual formation that is communal, charismatic, and embodied, revealing that discipleship is not an end in itself but a …

Assessing The Impact Of Climate Change On Harbor Seals: Haul-Out Patterns In Iceland Using Cmip6 Projections, Colin Lau

Independent Study Project (ISP) Collection

Harbor seals (Phoca vitulina) are known to exhibit a preference for specific environmental and weather conditions when hauling out, particularly during the pupping and molting cycles during summer. Climate change is projected to have a significant impact on the haul-out patterns and site conditions of harbor seals in Iceland, which could further diminish their dwindling population. A comprehensive literature review was conducted to identify and discuss the environmental variables that can affect haul-out probability. Among them, surface wind speed and air temperature are reported to have the biggest influence on harbor seal haul-out numbers between May and August. Climate projections …

Empowering Environmental Education In Portuguese Primary Schools: Energy Focused Curriculum Recommendations And Behavioral Change Framework Guided By Principles Of Developmental Psychology, Ellie Hanson

Independent Study Project (ISP) Collection

This paper explores the integration of principles of developmental psychology within the context of environmental education in Portugal to promote pro-environmental behavior, and specifically energy literacy energy conservation behaviors in primary school students. A review of current literature on the state of environmental education approaches in Portugal exhibits a significant lack of structure and direction for educators to teach students relevant topics in sustainability. Using a meta-theory of behavioral change, the present work connects the elements of the COM-B model of behavioral change to relevant aspects of middle childhood cognitive development using principles of two major theories of developmental psychology. …

Assessing The Progress And Effects Of Exotic Plant Invasions In A Sustainably Used Littoral Forest Fragment In Southeastern Madagascar, Grant Gerhardt

Independent Study Project (ISP) Collection

While it is important to conserve Madagascar’s unique natural forest environments and the biodiversity they contain, it is also essential that populations reliant on these ecosystems for their income and survival have access to the resources they provide. Sustainable use forests, designated by the IUCN as category VI protected areas, are the solution to meeting both of these conditions. At the same time, it is often the case that the use of forests invites disturbance, which in turn encourages the introduction and establishment of nonnative or invasive plant species. This study examines the degree to which the intensity of use …

Mushroom Composition Across An Elevational Gradient During The 2024 Wet Season In Mazumbai Forest Reserve, Tanzania, Christopher Brady

Independent Study Project (ISP) Collection

Mushrooms are key bioindicators that contribute greatly to ecological health, and their diversity is indicative of a healthy ecosystem. However, even with the vital role they play in ecological health, there are few studies which measure the diversity of mushrooms in Mazumbai Forest Reserve (MFR), Tanzania, Africa, and none which focus on diversity along the elevational gradient within the reserve (1300-1900m). This study measures the diversity and equitability of mushrooms growing in six elevational zones within MFR during the rainy season of 2024. A species checklist of mushrooms growing in MFR during the 2024 rainy season was created, tracking the …

Assessing The Impacts Of Anthropogenic Activities On Coral Reef Health In Ushongo, Tanzania Using Coral Diversity And Parrotfish Abundance As Indicators, Thao Mai

Independent Study Project (ISP) Collection

Coral reefs, covering two-thirds of our oceans, are vital and diverse ecosystems, earning them the nickname of “rainforests of the sea”. Despite occupying only 1% of the ocean’s floor, they support 25% of all marine species, providing shelter, nursery ground and food, all the while also protecting the coast and providing job opportunities for local communities. Considered keystone species, coral reefs are highly sensitive to disturbances caused by pollution, climate change, but also anthropogenic activities such as coastal development, destructive fishing practices and tourism, endangering their existence and the entire marine ecosystem. Parrotfish, a crucial resident of these ecosystems, often …

Sovereign Seeds: Analyzing The Sustainability Of Peasant Seeds In The Context Of Climate Change And Rural Exodus In Tunisia, Alice Carlson

Independent Study Project (ISP) Collection

How sustainable are peasant seeds? I answer this question on the basis of three elements: environment, economy, and social justice. Using interviews with farmers from various regions of Tunisia, an interview with an expert on climate change and migration, and an interview with a civil society organization working to promote sustainable agriculture, I found that peasant seeds are a sustainable solution for a suffering agricultural sector. Depleted water sources and drought are bringing to light the problems with water-intensive hybrid seeds, and farmers are losing money. As young men increasingly leave the agricultural sector, women are left behind, finding themselves …

Anuran Diversity And Abundance Across Two Sites With Varying Levels Of Light Pollution In El Valle De Antón, Coclé, Panamá, Jackson Dray

Independent Study Project (ISP) Collection

The impact of artificial light at night (ALAN) on anuran populations has been a subject of growing concern in ecological research. Anurans are particularly susceptible to the impacts of artificial light due to their nocturnal nature and an extensive exposure throughout various stages of life histories. Exposure to artificial light has been shown to impact the larval development and reproductive behavior of anurans. The impacts on anurans juvenile populations suggest a relationship between light pollution and anuran abundance. This study aimed to investigate the hypothesis that ALAN negatively affects the abundance and diversity of anurans. Field surveys were conducted in …
