Ecotoxicological Effects Of Sunscreen Derived Organic And Inorganic Uv Filters On Marine Organisms: A Critical Review, Anneliese A. Hodge, Frances E. Hopkins, Mahasweta Saha, Awadhesh N. Jha

School of Biological and Marine Sciences

Sunscreens are topical personal care products that provide protection against the sun's ultraviolet A (UVA) and ultraviolet B (UVB) radiation. Ultraviolet (UV) filters are compounds added to sunscreens to block, absorb, or reflect the sun's UV rays, but are of major emerging concern due to their widespread use and global distribution. They pose a significant risk to marine organisms owing to their chemical properties, including high lipophilicity which increases their bioavailability. The present review identifies and summarises the factors that contribute to UV filter pollution, their sources, pathways, and effects on marine organisms. We identify and evaluate the current knowledge …

New Ethereum-Based Distributed Pki With A Reward-And-Punishment Mechanism, Chong Gee Koa, Swee Huay Heng, Ji Jian Chin

School of Engineering, Computing and Mathematics

This paper explores the critical role of Public Key Infrastructure (PKI) in ensuring the security of electronic transactions, particularly in validating the authenticity of websites in online environments. Traditional Centralised PKIs (CPKIs) relying on Certificate Authorities (CAs) face a significant drawback due to their susceptibility to a single point of failure. To address this concern, Decentralised PKIs (DPKIs) have emerged as an alternative. However, both centralised and decentralised approaches encounter specific challenges. Researchers have made several attempts using blockchain-based PKI, which implements a reward and punishment mechanism to enhance the security of traditional PKI. Most of the attempts are focused …

Mesoscale Modeling For Predicting Effective Properties And Damage Behavior Of Geopolymer Concrete, Feiyu Shi, Shanshan Cheng, Longyuan Li

School of Engineering, Computing and Mathematics

Geopolymer concrete is a sustainable construction material and is considered as a promising alternative to traditional Portland cement concrete. However, there is still not much research on the effective properties and damage behavior of geopolymer concrete with consideration of its heterogeneous characteristics by means of mesoscale models combined with the regularized microplane damage model. Here, in this research, an easy and simpler approach for generating concrete mesoscale models and characterizing the angular characteristics of aggregate particles is presented. After the proposed mesoscale modeling was validated by numerical, experimental and theoretical models, it was employed further to predict the effective properties …

Is Sparse Local Ecological Knowledge Accurate Enough For Policy? A Seagrass Mapping Case Study From Five Greek Islands In The Eastern Aegean Sea, Konstantis Alexopoulos, Tim J. Grandjean, Anastasia Miliou, Theodoros Tsimpidis, Abigail Mcquatters-Gollop

School of Biological and Marine Sciences

The low cost, high applicability and community-based nature of Local Ecological Knowledge (LEK) data for mapping marine benthic habitats has become increasingly popular in recent years. Nonetheless, due to persisting technocratic distrust of LEK often stemming from the unquantifiable nature of bias, the embedding of empirical data at policy levels often lags. Currently, protocols rely on high participation from stakeholders, however, such quotas are often unfeasible, with common limiting factors being the low numbers of knowledgeable individuals in remote parts of the world, and the lack of community trust in the conservation mechanism. In this study, we test whether data …

Restoration Of River Connectivity Enables Long-Distance Spawning Migrations In A Potamodromous Fish, Dagmara Błońska, Ali Serhan Tarkan, Demetra Andreou, Jonathan D. Bolland, Peter Davies, Jamie R. Dodd, Phillipa Gillingham, Catherine Gutmann Roberts, Fatima Amat-Trigo, Sadi Aksu, Andrew Hindes, O. Jonas Palder, Mark Yeldham, J. Robert Britton

School of Biological and Marine Sciences

Rivers across the world are increasingly fragmented due to anthropogenic barriers, with the restoration of connectivity often using fish passes. Fish passes are, however, usually designed for anadromous species, despite ecologically important non-anadromous species being present in the communities impacted by fragmentation. To assess the outcomes for non-anadromous fishes of the installation of multiple fish passes and weir modifications, the movements of the potamodromous European barbel Barbus barbus were evaluated in the lower River Severn basin, western Britain, which was fragmented by six weirs (two on a tributary, four on the Severn mainstem). Movements of individual fish were measured using …

A Unified, Data-Informed Model For Shoreline Evolution Due To Longshore And Cross-Shore Processes, Mark Davidson, Emily Hunt, Nieves Valiente

School of Biological and Marine Sciences

Due partially to a changing global climate, there is an increasing need to develop a modelling approach capable of providing warnings of coastal evolution, including erosion at storm, interannual and decadal timescales and in complex coastal settings. This research presents a reduced complexity model with a common approach to predicting shoreline change due to cross-shore and longshore processes. The model architecture is designed to be flexible and data-informed, incorporating an Extended Kalman (eKF) for the assimilation of field measurements of shoreline change. Depending on the values of the optimised model free parameters resulting from the eKF assimilation, the longshore and …

State Space Model Of Airflow In The Human Vocal Apparatus, Ian Howard

School of Engineering, Computing and Mathematics

To simulate both airflow and air pressure required for speech production, we developed a nonlinear state-space model of airflow in the human speech apparatus. We modeled the lungs as a mechanical, force-driven piston pump venting into a simplified larynx model, represented as a valve with time-varying resistance to airflow. The pump incorporates the effects of elasticity, viscosity, friction, and inertia, as well as differential air pressure. To maintain a constant target airflow through the larynx, a proportional-derivative (PD) controller applies force and regulates the piston. The model was implemented in MATLAB. Simulation results demonstrate that the model can maintain a …

Developing An Artificial Intelligence Framework For Identifying Fusion Blood-Based Biomarkers In Alzheimer's Disease, Ali H. Al-Nuaimi, Mohammed Kamal Nsaif, Shaymaa Al-Juboori

School of Engineering, Computing and Mathematics

Alzheimer’s Disease (AD) is an irreversible neurological disorder, a major cause of disability among the elderly, with no effective therapeutic options currently available. It is an asymp-tomatic disease in the prodromal stages and begins many years before clinical appearances. Early diagnosis of AD allows patients to obtain appropriate healthcare assistance, accelerating the development of new medications. A biomarker that evaluates the alterations in the brain cells produced by AD in its preliminary periods might be significant for its early identification. Blood-based biomarkers (BBBMs) facilitate the early detection of AD. The BBBMs detection procedure is cost-efficient and minimally invasive. The aim …

School of Biological and Marine Sciences

Global calls for greater ocean protection have sparked renewed interest in very large marine protected areas (VLMPAs, >100,000 km²) to achieve management targets; however, their conservation value is debated. We assessed the suitability of a VLMPA (640,000 km²) in the Indian Ocean for capturing the movements of resident mobile marine megafauna. We found that 95% of foraging, breeding and/or locally migrating individuals occurred within the VLMPA despite variable habitat use; adult hawksbill turtles (Eretmochelys imbricata, n = 22, 6124 tracking days) foraged on mesophotic banks (>30 m depth), reef manta rays (Mobula alfredi, n = …

Speech-Aided Facial Video Super Resolution With Accurate Lip Motion And Enhanced Frequency Details, Shailza Sharma, Vivek Singh, Abhinav Dhall, Vinay Kumar

School of Engineering, Computing and Mathematics

Despite recent breakthroughs in face hallucination, video face hallucination remains a challenging task due to the issue of consistency across video frames. The temporal dimension in videos makes it difficult to learn facial motion and maintain color uniformity throughout the sequence. To address these challenges, we propose a novel audio-visual cross-modality support based video face hallucination network. The framework excels in learning fine spatiotemporal motion patterns by leveraging the correlation between movement of the facial structure and associated speech signal. Another significant challenge generic to face hallucination is blurriness around the key facial regions, such as mouth and lips. These …

Temperature-Driven Plasticity In Boldness, Its Predictability And Learning In The Beadlet Anemone, Actinia Equina, Samantha Simpson, Dunia Gonzales, Mark Briffa

School of Biological and Marine Sciences

Variation in ambient temperature is for poikilothermic animals a key driver of behavioural variation because of its multiplicative effects on metabolic rate. Apart from the fundamental environmental source of behavioural variation, understanding the effects of temperature is also important in the context of predicted climate change scenarios. In particular, behavioural responses to extreme temperature fluctuation could represent maladaptive responses to rapidly changing environments. However, behavioural responses to moderate temperature fluctuations, within ranges that are routinely experienced, likely represent adaptive plasticity. Recent studies have addressed this question within an animal personality framework, which can quantify the effects of temperature regime across …

The Great Scrape: The Clash Between Scraping And Privacy, Daniel J. Solove, Woodrow Hartzog

Faculty Scholarship

Artificial intelligence (AI) systems depend on massive quantities of data, often gathered by “scraping”—the automated extraction of large amounts of data from the internet. A great deal of scraped data contains people’s personal information. This personal data provides the grist for AI tools such as facial recognition, deep fakes, and generative AI. Although scraping enables web searching, archiving of records, and meaningful scientific research, scraping for AI can also be objectionable and even harmful to individuals and society.

Organizations are scraping at an escalating pace and scale, even though many privacy laws are seemingly incongruous with the practice. In this …

Working Paper: Zero-Sum Thinking, Meritocratic Beliefs, And Preferences For Basic Income And Universal Healthcare, David Chavanne

Economics Faculty Publications

This study uses survey responses to explore how support for basic income and universal healthcare is linked to zero-sum thinking and meritocratic beliefs. Consistent with earlier work, I find that zero-sum thinking and weaker meritocratic beliefs both lead to greater levels of support for basic income and universal healthcare. Using a path analysis, zero-sum thinking is also found to strengthen support for basic income and universal healthcare along two separate channels -- one via zero-sum thinking’s direct effect on policy support and a second via an indirect effect, whereby zero-sum thinking is attached to weaker beliefs in meritocracy, which in …

The Military's Constitutional Role, Brenner M. Fissell

Faculty Publications

A basic principle of the American constitutional order is that civilian authority must be supreme over that of the military. The violation of this principle by the British was one of the grievances enumerated in the Declaration of Independence, and the Framers responded with a Constitution that made military rule impossible. But why is so-called “civilian control” of the military so important? This deep normative question has yet to be thoroughly answered by scholars, most of who assume it away as a given. This Article takes up that task, using contemporary political theory to defend the principle of civilian control. …

Faculty Scholarship

This Article critically examines the pervasive issue of colorism within the entertainment industry and its profound impact on dark-skinned Black entertainers. Anti-Black colorism is discrimination against Black people with darker skin tones and Afrocentric features (i.e. darker eye color, kinkier hair, broader nose, fuller lips). Tracing the historical roots of colorism from the colonial era to contemporary times, the Article emphasizes how societal preferences for Eurocentric features and anti-Black racism have created and perpetuated a hierarchy that disadvantages darker-skinned individuals. It analyzes the underrepresentation and pay disparities faced by dark-skinned Black actors and actresses. It details the industry’s preference for …

Title Ix And Athlete Compensation In The Postamateurism Era, Erin E. Buzuvis

Faculty Scholarship

This Essay argues that Title IX applies to all manners of compensation that universities provide and facilitate to their athletes because of their athletic participation. This includes paying wages (when and if that becomes permissible), paying for NIL (when that permission takes effect), and facilitating payments from booster collectives that are working on those universities’ behalf (as happens now). The statute and its implementing regulations create a structure of substantive equality that is flexible enough to address even the changing landscape of college athletics as it applies to matters of compensation that were not contemplated by the drafters of the …

The Transnationalisation Of Civil Society In East Asia’S War Redress Movement, Timothy Webster

Faculty Scholarship

Transnational human rights litigation is commonly associated with developments in Europe and the Americas during the 1990s. But Asian actors have used legal mobilisation to hold corporate actors to account since at least the 1970s. This chapter charts the first usages of transnational litigation in East Asia’s Word War II redress movement, akin to the Holocaust Restitution movement of the West. Korean and Chinese forced labourers liaised with Japanese attorneys, activists and academics to press compensation claims against Japanese corporations for wartime human rights abuses in Tokyo. Legal mobilisation did not succeed in the traditional sense. Yet, the formation of …

Formal Victories And Roads Not Taken: Excavating Departures And Throughlines In Challenges To The Place Of Marriage, Linda C. Mcclain

Faculty Scholarship

A decade after Obergefell, Professor Mayeri’s fascinating and meticulously detailed new book, Marital Privilege: Marriage, Inequality, and the Transformation of American Law, tells the stories of “marriage’s challengers,”from the 1960s to the beginning of the twenty-first century.¹⁶ Along with the stories of some “well-known” lawyers, advocates, and scholars, Mayeri also “rescu[es]” the stories of now “obscure” Americans who “pushed marital boundaries” to protect their parental rights, their careers, or their “freedom to make decisions about their bodies and families.”¹⁷ Such rescue allows readers to “see change as a bottom-up as well as a top-down process.”¹⁸ Mayeri …

The Power Of Subnational Actors In Enforcement Of The Convention On Long-Range Transboundary Air Pollution, Wendy Erickson

Minnesota Journal of International Law, Vols. 28:2 onward (2019-present)

The Geneva Convention on Long-Range Transboundary Air Pollution (CLRTAP) was adopted in 1979 and continues to serve as the preeminent international framework for transboundary air pollution. The international community has used a range of multilateral and bilateral cooperative arrangements to address international movement of harmful pollutants. Each has had to contend with the issue of ensuring compliance among party States. CLRTAP faces challenges in addressing transboundary pollution in non-Western countries despite clear evidence that air pollution is harmful to human health and technological developments that enable more accurate tracking of pollutants. In the absence of a model assigning liability for …

The Alien Tort Statute And U.S. Extraterritorial Jurisdiction: Legal And Economic Corporate Governance Implications Beyond Al Shimari V. Caci Int'l, Gabriel Richardson

Minnesota Journal of International Law, Vols. 28:2 onward (2019-present)

This note is divided into four overall parts. To continue with the academic dialogue regarding the ATS, the first part (Part I) deals with the historical overview and case law of the ATS, while contrasting the development of extraterritoriality in the United States with that abroad (particularly, Europe). More specifically, the first part is divided into two subparts—Subpart A provides a comprehensive background and historical legal overview of the ATS and Subpart B discusses the international trend, particularly in Europe, in extending legal mechanisms to hold corporations accountable beyond their borders, unlike the United States—which, again, was once at the …

Design Problems, Mark P. Mckenna, Jessica Silbey

Faculty Scholarship

This Essay draws on our empirical research into designers and their work to investigate the limits of intellectual property law for achieving its goal of progress in the design context. We focus on two related aspects of our research and also address a pressing doctrinal question in design patent law. The two research questions we discuss are: (1) How do designers conceive of and solve design problems through innovative design practice?; and (2) How do designers incorporate human values of coherence, inclusivity, and sustainability in their process, imbuing their practice with a kind of politics? The related doctrinal question concerns …

Normalizing Facial Recognition Technology And The End Of Obscurity, Woodrow Hartzog, Evan Selinger, Judy Hyojoo Rhee

Faculty Scholarship

This article argues that facial recognition technology is the most dangerous surveillance tool ever invented. Given the unique threats this morally suspect tool poses to privacy, civil liberties, human flourishing, and democracy, the only appropriate response is a ban. To justify our position, we explain why facial recognition is distinctive among biometrics, clarify how even seemingly benign and positive uses of the technology can trigger dangerous normalization dynamics, and pinpoint why current United States laws (with reverberations in the EU’s AI Act) are designed to accelerate a slippery slope that makes mass surveillance nearly inevitable. Our most fundamental contribution lies …
