The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible.

Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

Analysis Of Research On The Effects Of Auditory Stimulation On Anxiety And Stress In Clinical And General Populations, Rebecca Lee

CMC Senior Theses

The use of auditory stimulation may be a useful method in treating clinical anxiety disorders, as well as aiding in coping with daily stress among general populations. The understanding of how certain forms of auditory stimulation can increase anxiety and stress is also critical so clinicians and the general population can approach decreasing anxiety and stress in the most effective way possible. The following paper will provide a literature review on studies published after the year 2000, analyzing the various impacts of different types of auditory stimulation, including impacts of music-therapy, music and noise at different frequencies, binaural beat stimulation, …

Threshold Concepts In Quantitative Reasoning, Judith Canner, Jennifer E. Clinkenbeard

Numeracy

The idea of “threshold concepts” has been used to identify discipline-based concepts that are critical to that academic area. Threshold concepts are often difficult for students to assimilate in a meaningful way but, once done, can be powerful for the learner. In general, threshold concepts are 1) transformative to learner thinking; 2) bounded by the discipline; 3) integrative with other concepts; and 4) irreversible once understood (Meyer and Land 2003). This paper presents five threshold concepts in quantitative reasoning (QR) developed by transdisciplinary faculty workgroups that may be applicable for non-mathematics disciplines as well. They are as follows: 1) QR …

The Standing Of Anger: Insights From The Debate(S) On Constructed Emotion, Andrew Holzer

CMC Senior Theses

In her book, Anger and Forgiveness: Resentment, Generosity, Justice, Martha Nussbaum argues that anger is inherently flawed because it fundamentally contains the desire for payback. To support her argument, she posits specific metaphysical claims about the nature of emotions like anger. This thesis is an extended critique of her metaphysical foundation from the perspective of empirical research in the neuroscience of emotion. The first reason to dispute this picture is descriptive; this view of anger is based on an outdated version of cognitive appraisal theory, which sees emotions as triggered directly by static moments of cognitive appraisal. The second …

Effect Of Cross-Modal Odor-Color Associations In Stroop-Like Paradigm, Anadel Ahlvin

Scripps Senior Theses

The investigation into synesthesia and its underlying mechanisms prompts inquiry into the prevalence of cross-modal associations within the general population and their influence on our lives, yet this domain remains relatively unexplored. This study aims to elucidate the impact of odor-color associations on odor recognition utilizing a Stroop-like paradigm. Participants were tasked with establishing odor-color associations, then subsequently recalling the odors paired with congruent, incongruent, or neutral colors. Reaction times and accuracy of odor recognition were recorded, and analysis revealed a significant effect of congruent versus incongruent color condition on odor recognition accuracy, with congruent color and odor having a …

Music And Healing In Aotearoa New Zealand: The Harmony Of The Land, Placehood, And Community In Māori And Pākehā Experiences Of Healing, Katherine Elise Callahan

Honors Theses

I explore the relationship between music and healing in Aotearoa New Zealand, and how healing is administered through the triadic relationship of the land, placehood, and community, using music as a vehicle for the carriage of this healing. In January of 2024, I traveled to Aotearoa New Zealand to gain a first-hand experience and account of this relationship through my own observations, and conducting interviews with Māori (the Indigenous people of Aotearoa New Zealand) individuals, and Pākehā (non-Māori) music therapists. Within this paper, I begin by providing context for this research within the fields of medical ethnomusicology, Indigenous studies, Māori …

Characterization Of Serx: A Putative Periplasmic Binding Protein In A Selenate Respiring Bacteria, Henry Jacques, Susan E. Childers

Honors Theses

A selenate respiring bacterium, Dechloromonas sp. A34, was isolated from a seleniferous mining site in southeastern Idaho. A34 was of interest due to its ability to respire up to 20 mM selenate, the highest concentration tested. The strain has been proposed to represent a new species of bacteria within the Dechloromonas genera, with the prospective name Dechloromonas selenatirespirans (manuscript in preparation). Our research presents characterization of a putative periplasmic binding protein found within an operon that contains genes encoding a putative selenate reductase. The gene, named serX (selenate reductase gene X), is 855 base pairs and encodes a putative …

The Social Implications Of Assisted Reproductive Technologies: An Analysis Of Feminist Discourse And Popular Media, Charlotte S. Buswick

Honors Theses

Assisted reproductive technologies (ARTs) have been a valuable tool in allowing many people to have children who previously struggled with infertility. However, feminists have raised the question: what impact do these new reproductive technologies have on women? This thesis investigates the discourse around the social implications of ARTs from the seventies to the present day. Looking at both feminist literature and portrayals of ARTs in women’s magazines, I performed a discourse analysis to track how the perception of the social implications of ARTs has changed over time. I also use a science, technology, and society (STS) studies lens to look …

Northern Shrimp In The Gulf Of Maine And The Impacts Of Climate Change, Alicia Hober

Honors Theses

Northern Shrimp (Pandalus borealis) populations within the Gulf of Maine collapsed in 2011 following the first year that sea surface temperature surpassed 10ºC. The population collapse resulting in a moratorium in 2014. The waters of the Gulf of Maine have been rising at a rate of 0.045ºC per year, changing predator distribution, prey distribution, as well as Northern Shrimp biological variables. There has been very little recovery to the Northern Shrimp stock despite the fishing moratorium and the answers behind the collapse and lack of recovery remains enigmatic. Therefore, this two-chapter study includes a literature review and a …

Black Rhino Conservation And Ranger Wellness In Namibia, Terra Gallo

Honors Theses

Wildlife rangers play an essential role in conserving biodiversity worldwide. Until recently, little was known about ranger working conditions and welfare. In 2019 the World Wildlife Fund (WWF) released a report that summarized survey results about ranger wellness from 7,110 rangers across multiple continents. However, the WWF study had geographic gaps and did not survey rangers from southern Africa, including the Republic of Namibia. In Namibia, rangers in the Kunene region are central to the conservation of the desert-adapted black rhino. Save the Rhino Trust (SRT) is a Namibian organization that supports rhino rangers and black rhino conservation. The aim …

Reviving Caribbean Scleractinian Corals: Medication In Ex-Situ Care, Christopher E. Cho

Honors Theses

The Caribbean basin is facing an unprecedented decline in coral reef health, with factors such as coral disease, climate change, and algal overgrowth contributing to the deterioration of these vital ecosystems. In response, land-based facilities have emerged to aid in coral conservation and restoration efforts. One aspect of these conservation efforts involves the treatment of coral ailments, which is still an emerging field within coral conservation. By medicating corals, researchers aim to combat diseases and alleviate stressors that threaten coral health. This practice holds promise for preserving genetic diversity and supporting future repopulation initiatives. This study evaluates the effectiveness of …

Interactional Queerscapes: Representations Of Men Attracted To Men In South Korea, Tegh Khosla

Honors Theses

This thesis explores the representations of men attracted to men (MAM) in South Korean media through the theoretical lens of queerscapes. Queerscapes refer to the physical and metaphorical spaces alternative queer existences occupy amidst dominant heteronormative environments. By analyzing a queer independent film, a bestselling novel, and a subversive boys’ love (BL) drama, this study examines how characters in these media actively carve out alternative spaces of existence. The first chapter delves into the concept of queerscaping as a verb to articulate direct conflict with intolerant institutions and dominant ideologies that seek to suppress non-normative sexualities. This precarious balancing act …

Sprtn Metalloprotease As A Target To Sensitize Cancer Cells To Crosslinking Chemotherapy, Cole J. Turner

Honors Theses

Bifunctional alkylating agents have demonstrated high clinical utility as a chemotherapeutic strategy against cancer. These compounds have been well-characterized for their capacity to exert cytotoxicity via interstrand DNA crosslinking. However, the same electrophilic chemistry can also form DNA-protein crosslinks (DPCs) whose contributions to these drugs’ antitumor effects have been less well-defined. Recently, the metalloprotease SPRTN has been implicated as a predominant mediator of DPC repair in mammalian cells. Previous work has demonstrated that SPRTN deficiency increases the sensitivity of cancer cells to DPC-inducing agents such as formaldehyde and cisplatin, but these findings have yet to be translated more broadly across …

Modification Of Marine Snail Microhabitats By Canopy-Forming Algae, Eleanor Mcgrath

Honors Theses

Brown algae, including the canopy-forming macroalgae Fucus distichus, are declining in abundance around the world due to stressors associated with climate change. Local extinction of Fucus impacts the intertidal community through cascading effects as the ecosystem loses a dominant primary producer at the base of the food web. However, Fucus is not only a resource species; it is also an ecosystem engineer. This thesis investigates the effect of Fucus extinction on the abundance of two herbivorous marine snails, L. saxatilis and L. obtusata, with a focus on the role of Fucus as a habitat- modifier. Specifically, I explored: …

The Physicians' Crusade: A Forgotten War On Abortion, Feminism, And The Diversification Of The United States, Lucinda B. Harden

Honors Theses

Abortion in the United States was accessible and widely practiced until the mid- nineteenth century. In 1857 the physicians’ crusade, an anti-abortion political movement led by prominent medical doctors around the country, instigated the widespread criminalization of abortion by the end of the century. I argue that physicians wielded their scientific authority to validate increasingly conservative attitudes about race and gender. They appealed to national xenophobic and sexist backlash that accompanied progressive changes like industrialization and the abolition of slavery, amplifying those fears and offering politicians a source of control over female sexuality and a growing immigrant population: the criminalization …

Measuring Nature’S Contributions To People Provided By Species In The Gulf Of Maine Rocky Intertidal Ecosystem, Madelyn L. Eippert

Honors Theses

Ecosystem services aim to quantify the value of nature provided to humans. However, Ecosystem services are typically measured at the level of the ecosystem as a whole and do not consider interactions between species in an ecosystem. Ultimately, the species in an ecosystem determine the services that are provided. Measuring ecosystem services at the landscape level misses the complex interactions and changing biodiversity of ecosystems. Currently, there is no accepted framework to link ecosystem services to species. In this thesis, I developed a framework to link Nature’s Contributions to People (NCP) to species. NCP includes 18 specific contributions (i.e. 18 …

Space Mining, Isabelle M. Thibault

Journal of Air Law and Commerce

The Outer Space Treaty, the leading source of law for activities in space, has laid out various limitations and regulations regarding actions in space and how space can be used. One of these limitations is commonly referred to as the “non-appropriation principle.” The non-appropriation principle prohibits nations from making claims of sovereignty over celestial bodies in space. This presents a problem as the space industry continues to progress because it causes uncertainty regarding the meaning of appropriation, what is classified as a celestial body, what acts are allowed, and who specifically is prohibited from acting. This Comment identifies these problems …

Optimizing Neural Networks For Iiot Attack Detection, Hamad Alblooshi

Theses

The Industrial Internet of Things (IIoT) stands as a revolutionary force, intertwining physical devices, sensors, and industrial systems to usher in advanced automation and data-driven decision-making across various sectors. However, this increased connectivity has exposed these systems to a growing array of cyber threats. Safeguarding IIoT environments becomes crucial to maintain the integrity, availability, and confidentiality of critical industrial processes. In response, this research explores the optimization of neural network parameters using Genetic Algorithms (GA). The application of GA has led to achieve a remarkable accuracy of 95% across various attack types. The results demonstrate a high performance in identifying …

A Comparison Of Adenosine Triphosphate With Other Metrics Of Microbial Biomass In A Gradient From The North Atlantic To The Chesapeake Bay, Alexander B. Bochdansky, Amber A. Beecher, Joshua R. Calderon, Alison N. Stouffer, Nyjaee N. Washington

OES Faculty Publications

A new, simplified protocol for determining particulate adenosine triphosphate (ATP) levels allows for the assessment of microbial biomass distribution in aquatic systems at a high temporal and spatial resolution. A comparison of ATP data with related variables, such as particulate carbon, nitrogen, chlorophyll, and turbidity in pelagic samples, yielded significant and strong correlations in a gradient from the tributaries of the Chesapeake Bay (sigma-t = 8) to the open North Atlantic (sigma-t = 29). Correlations varied between ATP and biomass depending on the microscopic method employed. Despite the much greater effort involved, biomass determined by microscopy correlated poorly with other …

Re-Evaluating Hydrogen Sulfide As A Sink For Cadmium And Zinc In The Oxic To Suboxic Upper Water Column Of The Pacific Ocean, N. R. Buckley, E. E. Black, J. A. Kenyon, N. T. Lanning, M. Sieber, T. M. Conway, J. N. Fitzsimmons, G. A. Cutter

OES Faculty Publications

Hydrogen sulfide is produced by heterotrophic bacteria in anoxic waters and via carbonyl sulfide hydrolysis and phytoplankton emissions under oxic conditions. Apparent losses of dissolved cadmium (dCd) and zinc (dZn) in oxygen minimum zones (OMZs) of the Atlantic and Pacific Oceans have been attributed to metal-sulfide precipitation formed via dissimilatory sulfate reduction. It has also been argued that such a removal process could be a globally important sink for dCd and dZn. However, our studies from the North Pacific OMZ show that dissolved and particulate sulfide concentrations are insufficient to support the removal of dCd via precipitation. In contrast, apparent …

A Model For Community-Driven Development Of Best Practices: The Ocean Observatories Initiative Biogeochemical Sensors Data Best Practices And User Guide, Hilary I.

OES Faculty Publications

The field of oceanography is transitioning from data-poor to data-rich, thanks in part to increased deployment of in-situ platforms and sensors, such as those that instrument the US-funded Ocean Observatories Initiative (OOI). However, generating science-ready data products from these sensors, particularly those making biogeochemical measurements, often requires extensive end-user calibration and validation procedures, which can present a significant barrier. Openly available community-developed and -vetted Best Practices contribute to overcoming such barriers, but collaboratively developing user-friendly Best Practices can be challenging. Here we describe the process undertaken by the NSF-funded OOI Biogeochemical Sensor Data Working Group to develop Best Practices for …

Interpreting An Archaean Paleoenvironment Through 3d Imagery Of Microbialites, Cecilia M. Howard, Nathan D. Sheldon, Selena Y. Smith, Nora Noffke

OES Faculty Publications

While stromatolites, and to a lesser extent thrombolites, have been extensively studied in order to unravel Precambrian (>539 Ma) biological evolution, studies of clastic-dominated microbially induced sedimentary structures (MISS) are relatively scarce. The lack of a consolidated record of clastic microbialites creates questions about how much (and what) information on depositional and taphonomic settings can be gleaned from these fossils. We used μCT scanning, a non-destructive X-ray-based 3D imaging method, to reconstruct morphologies of ancient MISS and mat textures in two previously described coastal Archaean samples from the ~3.48 Ga Dresser Formation, Pilbara, Western Australia. The aim of this …

Nitrogen Fixation At The Mid-Atlantic Bight Shelfbreak And Transport Of Newly Fixed Nitrogen To The Slope Sea, C. R. Selden, M. R. Mulholland, K. E. Crider, S. Clayton, A. Macías-Tapia, P. Bernhardt, D. J. Mcgillicuddy Jr., W. G. Zhang, P. D. Chappell

OES Faculty Publications

Continental shelves contribute a large fraction of the ocean's new nitrogen (N) via N₂ fixation; yet, we know little about how physical processes at the ocean's margins shape diazotroph biogeography and activity. Here, we test the hypothesis that frontal mixing favors N₂ fixation at the Mid-Atlantic Bight shelfbreak. Using the ¹⁵N₂ bubble release method, we measured N₂ fixation rates on repeat cross-frontal transects in July 2019. N₂ fixation rates in shelf waters (median = 5.42 nmol N L⁻¹ d⁻¹) were higher than offshore (2.48 nmol N L⁻¹ d⁻¹) …

Nitrogen Uptake Rates And Phytoplankton Composition Across Contrasting North Atlantic Ocean Coastal Regimes North And South Of Cape Hatteras, Yifan Zhu, Margaret R. Mulholland, Peter W. Bernhardt, Aimee Renee Neeley, Brittany Widner, Alfonso Macías Tapia, Michael E. Echevarria

OES Faculty Publications

Understanding nitrogen (N) uptake rates respect to nutrient availability and the biogeography of phytoplankton communities is crucial for untangling the complexities of marine ecosystems and the physical, biological, and chemical forces shaping them. In the summer of 2016, we conducted measurements of bulk microbial uptake rates for six ¹⁵N-labeled substrates: nitrate, nitrite, ammonium, urea, cyanate, and dissolve free amino acids across distinct marine provinces, including the continental shelf of the Mid-and South Atlantic Bights (MAB and SAB), the Slope Sea, and the Gulf Stream, marking the first instance of simultaneously measuring six different N uptake rates in this dynamic region. …

Diel Vertical Migration Rates Of The Dinoflagellate Species Margalefidinium Polykrikoides In A Lower Chesapeake Bay Tributary, S. Clayton, Jacqueline B. Chrabot, Michael Echevarria, Leah Gibala-Smith, Kathryn Mogatas, Peter Bernhardt, Margaret R. Mulholland

OES Faculty Publications

Margalefidinium polykrikoides is a mixotrophic dinoflagellate harmful algal bloom (HAB) species that blooms annually in the lower Chesapeake Bay. M. polykrikoides undertakes a diel vertical migration (DVM) which may give it a competitive advantage over purely phototrophic organisms who cannot access deeper nutrient pools and allow it to form large toxic blooms. Laboratory-based estimates of M. polykrikoides’ DVM rates suggest that it is one of the fastest known dinoflagellate swimmers and understanding this behavior is likely important for modeling and predicting M. polykrikoides blooms. However, to date, no field-derived estimates of M. polykrikoides’ DVM rates have been made in the …

A Proxy System Modeling Approach To Combining Tree-Ring And Sediment-Based Paleotempestological Records, Elizabeth J. Wallace, Sylvia Dee, Joshua Bregy, Kerry A. Emanuel

OES Faculty Publications

The short and biased observational record of tropical cyclones (TCs) limits scientific understanding of how these destructive storms respond to climate forcing. Paleohurricane records use natural archives (tree rings, coarse-grained sediment) to reconstruct TC properties (frequency and intensity of rainfall, wind) over the past few hundreds to thousands of years. However, different sensitivities and sampling biases in the various paleohurricane proxies restrict our ability to compile these records into regional or basin-scale TC estimates. Here we test how well pseudo tree-ring records of paleohurricanes capture TC rainfall and occurrence. Using a large set of statistically downscaled storms forced with the …
