Ai, Equity, And The Ip Gap, Daryl Lim
Ai, Equity, And The Ip Gap, Daryl Lim
SMU Law Review
Artificial intelligence (AI) has helped determine vaccine recipients, prioritize emergency room admissions, and ascertain individual hires, sometimes doing so inequitably. As we emerge from the Pandemic, technological progress and efficiency demands continue to press all areas of the law, including intellectual property (IP) law, toward incorporating more AI into legal practice. This may be good when AI promotes economic and social justice in the IP system. However, AI may amplify inequity as biased developers create biased algorithms with biased inputs or rely on biased proxies. This Article argues that policymakers need to take a thoughtful and concerted approach to graft …
New Political Ecologies Of Renewable Energy, Sarah Knuth, Ingrid Behrsin, Anthony Levenda, James Mccarthy
New Political Ecologies Of Renewable Energy, Sarah Knuth, Ingrid Behrsin, Anthony Levenda, James Mccarthy
Geography
The critique of fossil fuel regimes has been a foundational concern for the field of political ecology, in its drives to expose the injustices and harms of energy extractivism and its early warnings of the climate crisis. However, it is increasingly evident that renewable energy sources and their infrastructures will carry their own costs and trade-offs, and that critique, resistance and alternative movement-building are needed to forge a truly just renewable energy transition. This theme issue underlines the many ways in which political ecology is well-positioned to lead critical and engaged scholarship in support of energy/climate justice. In this introduction …
Phytoplankton Bloom Stages Estimated From Chlorophyll Pigment Proportions Suggest Delayed Summer Production In Low Sea Ice Years In The Northern Bering Sea, Clare B. Gaffey, Karen E. Frey, Lee W. Cooper, Jacqueline M. Grebmeier
Phytoplankton Bloom Stages Estimated From Chlorophyll Pigment Proportions Suggest Delayed Summer Production In Low Sea Ice Years In The Northern Bering Sea, Clare B. Gaffey, Karen E. Frey, Lee W. Cooper, Jacqueline M. Grebmeier
Geography
Decreased sea ice cover in the northern Bering Sea has altered annual phytoplankton phenology owing to an expansion of open water duration and its impact on ocean stratification. Limitations of satellite remote sensing such as the inability to detect bloom activity throughout the water column, under ice, and in cloudy conditions dictate the need for shipboard based measurements to provide more information on bloom dynamics. In this study, we adapted remote sensing land cover classification techniques to provide a new means to determine bloom stage from shipboard samples. Specifically, we used multiyear satellite time series of chlorophyll a to determine …
Chinese Neoglobalization In East Africa: Logics, Couplings And Impacts, Pádraig R. Carmody, James T. Murphy
Chinese Neoglobalization In East Africa: Logics, Couplings And Impacts, Pádraig R. Carmody, James T. Murphy
Geography
The most significant case of transnational state capitalism today is China's Belt and Road Initiative (BRI) which seeks to expand/extend the country's geoeconomic and geopolitical integrations globally. We conceptualise the BRI as manifest principally through industrial offshoring, infrastructure investments and exports from China. These vectors articulate with particular places, forming transnational couplings that shape development outcomes. We examine the BRI's couplings and their development implications in the East African countries of Djibouti, Ethiopia and Kenya where China has engaged significantly. We demonstrate the contingent manner of BRI's variegations; its pragmatism, flexibility, and limitations as a hegemonic or developmental project.

The Pacific Drought Knowledge Exchange: A Co-Production Approach To Deliver Climate Resources To User Groups, Ryan J. Longman, Abby G. Frazier, Christian P. Giardina, Elliott W. Parsons, Sierra Mcdaniel
Geography
Drought is a growing threat to hydrological, ecological, agricultural, and socio-cultural systems of the tropics, especially tropical islands of the Pacific where severe droughts can compromise food and water security. Overcoming barriers to knowledge sharing between land managers and researchers is a critical cross-sector strategy for engaging and mitigating or adapting to drought. Here we describe the establishment and functioning of the Pacific Drought Knowledge Exchange (PDKE), which provides users with easier access to: (1) sector- and geography-specific climate information; (2) better and more comprehensive information; (3) improved technical assistance; and (4) a more collaborative information-transfer environment through participation in …
The Influence Of Burn Severity On Post-Fire Spectral Recovery Of Three Fires In The Southern Rocky Mountains, Jaclyn Guz, Florencia Sangermano, Dominik Kulakowski
The Influence Of Burn Severity On Post-Fire Spectral Recovery Of Three Fires In The Southern Rocky Mountains, Jaclyn Guz, Florencia Sangermano, Dominik Kulakowski
Geography
Increased wildfire activity and altered post-fire climate in the Southern Rocky Mountains has the potential to influence forest resilience. The Southern Rocky Mountains are a leading edge of climate change and have experienced record-breaking fires in recent years. The change in post-fire regeneration and forest resilience could potentially include future ecological trajectories. In this paper, we examined patterns of post-fire spectral recovery using Landsat time series. Additionally, we utilized random forest models to analyze the impact of climate and burn severity on three fire events in the Southern Rocky Mountains. Fifteen years following the fires, none of the burned stands …
Addressing Big Tech’S Market Power: A Comparative Institutional Approach, Thomas A. Lambert
Addressing Big Tech’S Market Power: A Comparative Institutional Approach, Thomas A. Lambert
SMU Law Review
This Article provides a comparative institutional analysis of the three leading approaches to addressing the market power of large digital platforms: (1) traditional antitrust law, the approach thus far taken in the United States; (2) ex ante conduct rules, the approach embraced by the European Union’s Digital Markets Act and several bills under consideration in the U.S. Congress; and (3) ongoing agency oversight, the approach embraced by the United Kingdom with its newly established “Digital Markets Unit.” After identifying the general advantages and disadvantages of each approach, the Article examines how they are likely to play out in the context …

Albedo Changes Caused By Future Urbanization Contribute To Global Warming, Zutao Ouyang, Pietro Sciusco, Tong Jiao, Sarah Feron, Cheyenne Lei, Fei Li, Ranjeet John, Peilei Fan, Xia Li, Christopher A. Williams, Guangzhao Chen, Chenghao Wang, Jiquan Chen
Geography
The replacement of natural lands with urban structures has multiple environmental consequences, yet little is known about the magnitude and extent of albedo-induced warming contributions from urbanization at the global scale in the past and future. Here, we apply an empirical approach to quantify the climate effects of past urbanization and future urbanization projected under different shared socioeconomic pathways (SSPs). We find an albedo-induced warming effect of urbanization for both the past and the projected futures under three illustrative scenarios. The albedo decease from urbanization in 2018 relative to 2001 has yielded a 100-year average annual global warming of 0.00014 …

Assessing Inter-Metric Correlation For Multi-Document Summarization Evaluation, Michael Ridenour
Assessing Inter-Metric Correlation For Multi-Document Summarization Evaluation, Michael Ridenour
Maseeh Summer Undergraduate Research Experience
Background: (i) Automatic Text Summarization involves generating concise summaries of natural language text documents by using machine learning systems. (ii) Most prior research has focused on developing systems that can summarize a single document (for example a news article), but recent research has developed systems that can summarize a cluster of multiple documents (for example Tweets or customer reviews). (iii) Multi-document summarization is more challenging due to the higher diversity of information in the source documents.

“A Force Created”: The U.S. Chamber Of Commerce And The Politics Of Corporate Immunity, Myriam E. Gilles
Articles
Upon its founding in 1912, the U.S. Chamber of Commerce was conceived as a “force created” to exert “a beneficent influence upon our national life” by integrating the views of the business community into governmental policies and regulations. That a force was created is beyond question. Beneficence is a separate issue.
Moonshots, Matthew Wansley
Moonshots, Matthew Wansley
Articles
In the last half-century, technological progress has stagnated. Rapid advances in information technology disguise the slow pace of productivity growth in other fields. Reigniting technological progress may require firms to invest in moonshots—long-term projects to commercialize innovations. Yet all but a few giant tech firms shy away from moonshots, even when the expected returns would justify the investment. The root of the problem is corporate structure. The process of developing a novel technology does not generate the kind of interim feedback that shareholders need to monitor managers and managers need to motivate employees. Managers who anticipate these agency problems invest …

Responding To Mass, Computer-Generated, And Malattributed Comments, Steven J. Balla, Reeve Bull, Bridget C.E. Dooling, Emily Hammond, Michael A. Livermore, Michael Herz, Beth Simone Noveck
Articles
A number of technological and political forces have transformed the once staid and insider dominated notice-and-comment process into a forum for large scale, sometimes messy, participation in regulatory decisionmaking. It is not unheard of for agencies to receive millions of comments on rulemakings; often these comments are received as part of organized mass comment campaigns. In some rulemakings, questions have been raised about whether public comments were submitted under false names, or were automatically generated by computer “bot” programs. In this Article, we examine whether and to what extent such submissions are problematic and make recommendations for how rulemaking agencies …
“Never Anything About The Asian Experience”: An Asiancrit Analysis Of Asian American Teachers In The Midwest, Jung Kim
Education Department Faculty Articles
Although Asian Americans are the fastest-growing racial minority group in the United States, projected to be 10% of the population by 2050, they only comprise 2% of the teaching force. There is relatively little research about the experiences, recruitment efforts, or retention of Asian American teachers. This qualitative study seeks to add to the extant literature by seeking to better under the experiences of Asian American pK-12 teachers in the Midwest, primarily in northern Illinois. This study draws upon both a sociopolitical understanding of being Asian American and three specific tenets of AsianCrit: (re)constructive history; story, theory, and praxis; and …

Data Catalog
UV is a proven decontamination tool for microbial pathogens, including the SARS-CoV-2 virus. Lower log inactivation was observed on FFRs than would have been predicted by aqueous-based UV dose-response data for MS-2 bacteriophage and E. coli. Results have demonstrated that FFR materials yield varying results in terms of effective disinfection in experiments conducted on KN95 and N95 face respirators. The highest inactivation for both surrogates was observed with respirator KN95 B. The respirator yielded 3 and 2.75 log inactivation for E. coli and MS-2, respectively at UV doses of 1500 mJ/cm2. KN95 A yielded the lowest …

Experimental Investigation Of Asphaltene Deposition And Its Impact On Oil Recovery In Eagle Ford Shale During Miscible And Immiscible Co2huff-N-Puff Gas Injection, Mukhtar Elturki, Abdulmohsin Imqam
Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works
One of the challenges in extracting oil from unconventional resources using hydraulic fracturing and horizontal drilling techniques is the low primary recovery rate, which is caused by the ultra-small permeability of these resources. Consequently, it is essential to investigate gas injection methods to produce the trapped oil in shale formations. However, the injection process can cause asphaltene depositions inside the reservoir, leading to plugging of pores and oil recovery (OR) reduction. There has been limited research on using gas injection techniques to improve oil production in tight/unconventional resources, although carbon dioxide (CO2) and gas-enhanced oil recovery methods have been used …
Chemical Modification Of Biomaterials For Local Delivery Of Anti-Biofilm Molecules, Zoe Harrison
Chemical Modification Of Biomaterials For Local Delivery Of Anti-Biofilm Molecules, Zoe Harrison
Electronic Theses and Dissertations Archive
There is a great clinical need for effective methods to prevent infection following musculoskeletal trauma caused by severe injuries or implantation surgeries. Up to 80% of infections are due to the formation of microbial biofilms, which are difficult to eradicate as they possess mechanisms to evade immune cell clearance and withstand antibiotic treatment. The persistence of biofilms as well as the rise of multi-drug resistant bacterial strains further exemplify the need for non-antibiotic therapeutics to hinder bacterial growth. By incorporating anti-biofilm agents into biomaterials, the incidence of infection will decrease, as will patient trauma and hospitalization costs. The overall research …

Factors Impacting Advanced Math Course-Taking: A Multilevel Modeling Analysis Of The Hsls:09, Shelby Gayle Roberts
Electronic Theses and Dissertations Archive
The United States continues to lag other first-world countries in the number of students prepared to enter the STEM workforce. Research has shown that taking advanced math courses during high school better prepares students to enter college STEM programs (Byun et al., 2015; Chen, 2016). Both student and school characteristics often shape which courses students take in secondary school. Previous academic achievement and performance along with motivational factors, like expectations, math identity and self-efficacy, and students’ valuation of mathematics work concomitantly to shape students’ math course enrollments in high school (Attewell & Domina, 2008; Burkman & Lee, 2003; Maltese & …

Application Of Local Knowledge For Better Characterization And Modeling Of Urban Pluvial Flooding, Koorosh Azizi
Electronic Theses and Dissertations Archive
Urban pluvial flooding (UPF) resulting from localized, intense, rainfall‐generated ponding and overland flow causes a range of socio-environmental impacts. UPF is driven by a complex set of interconnected factors, including physical, historical, social, cultural, institutional, and economic conditions. Its impacts are increasing due to both biophysical change (e.g., global warming) and the interactions between the human and physical dimensions of the urban environment (e.g., land-use change). Notwithstanding its complexity and the rather low level of attention it has received in both research and practice, UPF is an issue that needs to be tackled from a comprehensive perspective. Although different integrated …
