Polyaniline Nano Films Synthesis In One Step Via Chemical Oxidative Polymerization, Amal Shakir Abbood, Ibraheem Jaleel Ibraheem

Baghdad Science Journal

Polyaniline films were successfully synthesized in this study using an oxidative polymerization method at temperatures ranging from 0 to 4 ° C. Polyaniline films were deposited using a single step of chemical oxidative polymerization rather than electrochemical polymerization. The polyaniline was examined using FTIR, XRD, SEM, AFM, and Four Point Probe. This result demonstrates that polyaniline synthesized using this method has a uniform morphology, small size (17 to 40) nm, high crystallinity, and high conductivity (9.42 s/cm).

The Role Of Chlorella Vulgaris In Reducing Some Pharmaceutical Wastes Toxicity In Clam Pseudodontopsis Euphraticus, Zahraa H. Obaid, Nuha F. Kadhim, Jasim Mohammed Salman

Baghdad Science Journal

Applications of microalgae in environmental studies have recently increased. Current uses of immobilized microalga Chlorella vulgaris include reducing pharmaceutical substances such as amoxicillin AMX and potassium dichromate K2Cr2O7 on freshwater clam Pseudodontopsis euphraticus as a biotic model. Recent research pointed out a change in biomarkers of oxidative stress in an evaluation of induced toxicity. Where clams were exposed to different concentrations100, 200, and 400 mg/L for 7 days and 20, 30, and 50 mg/L for 5 days of amoxicillin and potassium dichromate, respectively. The results showed that exposure to AMX and K2Cr2O7 led to a significant change in the activity …

The Affective Embeddings Of Gacha Games: Aesthetic Assemblages And The Mediated Expression Of The Self, Orlando Woods

Research Collection School of Social Sciences

This paper argues that the motivations for investing money in gacha games can be a function of the affective embedding of players within the game, and the game within broader circuits of cultural affinity and appeal. Whilst research on gacha games – and the specific role of loot boxes therein – has emphasised their associations with gambling, I contend that affect is another trigger that can motivate seemingly irrational playing behaviours. The affective embeddings of gacha games motivate players to curate aesthetic assemblages of virtual content that enable the mediated expression of the self. Drawing on qualitative data generated amongst …

Public Service Motivation And Job Satisfaction Amid Covid-19: Exploring The Effects Of Work Environment Changes, Seulki Lee, Chongmin Na

Research Collection School of Social Sciences

The COVID-19 pandemic has brought critical changes to job demands and resources, which in turn affect employee motivation and outcomes. This study explores how COVID-19–induced work intensity and COVID-19–related organizational support influence public service motivation (PSM) and job satisfaction. Using survey data from a nationally representative sample of 1,430 South Korean central government employees collected during the pandemic (May–June 2020), we find that COVID-19–induced work intensity is positively associated with PSM, which in turn has a positive association with job satisfaction. We also find that COVID-19–related organizational support has both direct and indirect associations with job satisfaction through PSM. These …

Merit And Inequality: Confucian And Communitarian Perspectives On Singapore's Meritocracy, Sor-Hoon Tan

Research Collection School of Social Sciences

This paper compares criticisms of Singapore’s meritocracy, especially against its impact on income disparities and class divisions, with Michael Sandel’s critique of the meritocratic ethic in the United States. Despite significant differences in their history and politics, meritocracy has similar dysfunctions in both societies, allowing us to draw theoretical conclusions about meritocracy as an ideal of governance. It then contrasts Sandel’s communitarian critique of meritocracy with recent Confucian promotion of political meritocracy and meritocratic justice and argues that the Confucian principle of “promoting the virtuous and talented” is different from the contemporary conception of meritocracy. Textual evidence indicates that a …

Artificial Intelligence Model Predicts Sudden Cardiac Arrest Manifesting With Pulseless Electric Activity Versus Ventricular Fibrillation, Hoang Nhat Pham, Angelo Salvucci, Jonathan Jui, Kyndaron Reinier, Piotr J Slomka, Sumeet S Chugh

Faculty, Staff and Student Publications

BACKGROUND: There is no specific treatment for sudden cardiac arrest (SCA) manifesting as pulseless electric activity (PEA) and survival rates are low; unlike ventricular fibrillation (VF), which is treatable by defibrillation. Development of novel treatments requires fundamental clinical studies, but access to the true initial rhythm has been a limiting factor.

METHODS: Using demographics and detailed clinical variables, we trained and tested an AI model (extreme gradient boosting) to differentiate PEA-SCA versus VF-SCA in a novel setting that provided the true initial rhythm. A subgroup of SCAs are witnessed by emergency medical services personnel, and because the response time is …

Major Questions About Presidentialism: Untangling The “Chain Of Dependence” Across Administrative Law, Jodi L. Short, Jed Handelsman Shugerman

Faculty Scholarship

A contradiction about the role of the president has emerged between the Roberts Court’s Article II jurisprudence and its Major Questions Doctrine jurisprudence. In its appointment and removal decisions, the Roberts Court claims that the president is the “most democratic and politically accountable official in Government” because the president is “directly accountable to the people through regular elections,” an audacious new interpretation of Article II; and it argues that tight presidential control of agency officials lends democratic legitimacy to the administrative state. We identify these twin arguments about the “directly accountable president” and the “chain of dependence” as the foundation …

Sports Participation By Athletes With Cardiovascular Disease, Matthew W. Martinez, Michael J. Ackerman, George J. Annas, Aaron L. Baggish, Sharlene M. Day, Kimberly G. Harmon, Jonathan H. Kim, Benjamin D. Levine, Margot Putukian, Rachel Lampert

Faculty Scholarship

Millions of young people participate in competitive sports, with well-documented physical and psychological benefits.1 Athletes may be diagnosed with cardiovascular disease (CVD) during evaluation of symptoms, routine preparticipation screening, or clinically indicated family screening. When this occurs, decisions about return-to-play (RTP) are difficult, especially in circumstances when risk may exist or be unknown. Historically, expert consensus documents such as the Bethesda Conference Proceedings,2 provided a “yes/no” approach to RTP after a diagnosis of a CVD such as hypertrophic cardiomyopathy (HCM) or long QT syndrome (LQTS). These recommendations were made with a paucity of data, and were predicated on a zero-risk …

Effect Of Chloropicrin And Metam Sodium On Soil Nitrogen Dynamics In California Strawberry Production, Colin Timothy Koubek

Plant Sciences

California strawberries (Fragaria x ananassa Duch.) bring in ~3 billion yearly for the state's economy. Strawberry growers use fumigants like chloropicrin and metam sodium to manage a variety of soilborne diseases in conventional production. The yield-boosting effects of fumigation on strawberries are often attributed to disease management, but the ‘fertilizer effect’ from mineralization may play an equally significant role. This experiment conducted in a grower field sought to find out the influence that fumigation had on the mineralization of soil organic nitrogen and if preplant fertilizer application affected early season nitrogen (N). There were six treatments: control, control with controlled …

Deconstructing Burglary, Ira P. Robbins

Scholarly Articles in Law Reviews & Journals

The law of burglary has long played a vital role in protecting hearth and home. Because of the violation of one’s personal space, few crimes engender more fear than burglary; thus, the law should provide necessary safety and security against that fear. Among other things, current statutes aim to deter trespassers from committing additional crimes by punishing them more severely based on their criminal intent before they execute their schemes. Burglary law even protects domestic violence victims against abusers who attempt to invade their lives and terrorize them.

However, the law of burglary has expanded and caused so many problems …

Investigating The Effects Of Alcohol Consumption On Manual And Automated Driving: A Systematic Review, Miaomiao Dong, Yuni Lee, Jackie Cha, Gaojian Huang

Mineta Transportation Institute

There are direct correlations between drunk driving and car-related injuries, disabilities, and death. Autonomous vehicles (AVs) may provide useful driver support systems to prevent or reduce road accidents. However, AVs are not yet fully automated and require human drivers to take over the vehicle at times. Therefore, understanding how alcohol affects driving performance in both manual and automated driving is important because manual drives may offer insights into the takeover process in AVs. A systematic review of 53 articles from eight databases was conducted. Findings were categorized based on the human information processing model, which can be extended to the …

Understanding Workforce Diversity In The Transit Industry: Establishing A Baseline Of Diversity Demographics, Asha W. Agrawal, Evelyn Blumenberg, Anastasia Loukaitou-Sideris, Brittney Lu

Mineta Transportation Institute

This study provides baseline data on the status of the racial/ethnic and gender diversity of the transit agency workforce in the U.S. and identifies potential barriers and promising practices for diversifying this workforce. Public transit agencies function best when the diversity of their workforce represents the communities they serve, yet previous research finds an underrepresentation of women and minorities in senior and managerial roles, along with an overconcentration of men and workers of color—particularly Black workers—in operational roles (e.g., drivers, janitors).

The study updates those earlier studies with newer data drawn from five discrete research tasks: 1) review of the …

Advancing Occupational Health In Mining: Investigating Low-Cost Sensors Suitability For Improved Coal Dust Exposure Monitoring, Mirza Muhammad Zaid, Nana Amoah, Ashish Kakoria, Yang Wang, Guang Xu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Exposure to coal dust in underground coal mines poses significant health risks to workers, including the development of diseases such as coal workers' pneumoconiosis and silicosis. Current available methods for monitoring coal dust exposure are expensive and time-consuming, necessitating the exploration of alternative approaches. Low-cost light scattering particulate matter sensors offer a promising solution, and its development in recent years has demonstrated some success in air quality monitoring However, its application in sensing coal particles is limited partially due to that the operating condition in a mine is different than the atmosphere. Thus, the objective of this paper is to …

Improved Subseasonal Prediction Of South Asian Monsoon Rainfall Using Data-Driven Forecasts Of Oscillatory Modes, Eviatar Bach, Venkat Krishnamurthy, Safa Mote, Jagadish Shukla, A. Surjalal Sharma, Eugenia Kalnay, Michael Ghil

Mathematics and Statistics Faculty Publications and Presentations

Predicting the temporal and spatial patterns of South Asian monsoon rainfall within a season is of critical importance due to its impact on agriculture, water availability, and flooding. The monsoon intraseasonal oscillation (MISO) is a robust northwardpropagating mode that determines the active and break phases of the monsoon and much of the regional distribution of rainfall. However, dynamical atmospheric forecast models predict this mode poorly. Data-driven methods for MISO prediction have shown more skill, but only predict the portion of the rainfall corresponding to MISO rather than the full rainfall signal. Here, we combine state-of-the-art ensemble precipitation forecasts from a …

Data Sovereignty And Trade Agreements: Three Digital Kingdoms, Henry S. Gao

Research Collection Yong Pung How School Of Law

For centuries, international lawyers have wrestled with the relationship between national sovereignty and international law. This is also the case of international trade law, where the tension between trade liberalization and national sovereignty culminated in the famous “Great 1994 Sovereignty Debate” between the late Prof. John Jackson and other leading scholars when the WTO came into being. As we enter the digital age, the issue of sovereignty resurfaced once again in the form of data sovereignty. In this paper, I will examine provisions in trade agreements which deal with data sovereignty issues, such as restrictions on data flow such as …

Research Collection College of Integrative Studies

As global warming and urbanisation intensify unabated, a growing share of the human population is exposed to dangerous heat levels. Trees and forests can effectively mitigate such heat alongside numerous health co-benefits like improved mental wellbeing. Yet, which forest types are objectively and subjectively coolest to humans, and how thermal and mental wellbeing interact, remain understudied. We surveyed 223 participants in peri-urban forests with varying biodiversity levels in Austria, Belgium and Germany. Using microclimate sensors, questionnaires and saliva cortisol measures, we monitored intra-individual changes in thermal and mental states from non-forest baseline to forest conditions. Forests reduced daytime modified Physiologically …

The Fourier–Legendre Series Of Bessel Functions Of The First Kind And The Summed Series Involving 1F2 Hypergeometric Functions That Arise From Them, Jack C. Straton

Physics Faculty Publications and Presentations

The Bessel function of the first kind JN^(kx) is expanded in a Fourier–Legendre series, as is the modified Bessel function of the first kind IN^(kx). The purpose of these expansions in Legendre polynomials was not an attempt to rival established numerical methods for calculating Bessel functions but to provide a form for JN^(kx) useful for analytical work in the area of strong laser fields, where analytical integration over scattering angles is essential. Despite their primary purpose, one can easily truncate the series at 21 terms to provide 33-digit accuracy that matches the IEEE extended precision in …
