Health Services and Informatics Research

Media use during childhood has quickly become a norm across the United States and in other countries. One area still not well understood is the development of problematic (or maladaptive and disruptive) media use in children. This research examines the role of attachment security as a central component in the development of problematic media use over time in a sample of 248 parent-child dyads (9.50% African American, 20.66% Hispanic, 62.81% White, 2.07% Asian, 4.96% other ethnicities). We examined the relationship between attachment security and problematic media use one and 2 years later. We then constructed a mediation model examining parent …

The Conceptual Review On The Effect Of Corporate Governance Monitoring Mechanisms On Tax Avoidance, Eveana Mosuin, Nor Balkish Zakaria, Yvonne Joseph Ason

ASEAN Journal on Science and Technology for Development

Taxes are the primary source of revenue for many nations in order to increase budget revenues and fund national development. Taxation serves multiple purposes because it can positively impact a nation's investment, education, social and economic development. However, tax authorities require assistance with the issue of tax non-compliance, which impedes tax administration and collection. One of the categories of tax non-compliance is tax avoidance, which is one of the company's strategies for legally reducing its tax burden by exploiting loopholes in tax regulations to minimise tax liability. Tax avoidance is when a company follows a particular tax strategy in the …

One-Pot Microwave-Assisted Approach Of Polydiacetylene/Zinc Oxide Nanocomposite For Reversible Thermochromic, Chanita Khanantong, Thanutpon Srinopkun, Thitirut Boonmak, Jintana Siriboon

Journal of Metals, Materials and Minerals

This study introduces a new technique to fabricate the reversible poly(PCDA/ZnO) nanocomposites thermochromism. Our preparation process is the solution-mixing method, which is supported by microwave synthesis time instead of ultrasonic bath or stirrer. The presence of ethanol molecules in aqueous media in the solution-mixing method induces dipolar polarization. In addition, the presence of Zn2+ leaking out of the ZnO can produce ionic polarization. These factors affect the shape of poly(PCDA/ZnO) nanocomposites based on their thermochromic properties. The optical properties of poly(PCDA/ZnO) nanocomposite were determined through UV-Vis absorption spectroscopy. The morphology of this nanocomposite was examined by scanning electron microscopy, and …

The Meme Stock Fenzy: Origins And Implications, Dhruv Aggarwal, Albert H. Choi, Yoon-Ho Alex Lee

Articles

In 2021, several publicly traded companies, such as GameStop, Bed Bath & Beyond, and AMC, became “meme stocks,” experiencing a sharp rise in their stock prices through a dramatic influx of retail investors into their shareholder base. Analyses of the meme stock surge and its implications for corporate governance have focused on the idiosyncratic creation of online communities around particular stocks during the COVID-19 pandemic. In this Article, we argue that the emergence of meme stocks is part of longer-running and more structural digital transformations in trading, investing, and governance. On the trading front, the abolition of commissions by major …

Research Access To Social Media Data: Lessons From Clinical Trial Data Sharing, Christopher J. Morten, Gabriel Nicholas, Salomé Vilgoen

Articles

For years, social media companies have sparred with lawmakers over how much independent access to platform data they should provide researchers. Sharing data with researchers allows the public to better understand the risks and harms associated with social media, including areas such as misinformation, child safety, and political polarization. Yet researcher access is controversial. Privacy advocates and companies raise the potential privacy threats of researchers using such data irresponsibly. In addition, social media companies raise concerns over trade secrecy: the data these companies hold and the algorithms powered by that data are secretive sources of competitive advantage. This Article shows …

Rethinking Innovation At Fda, Rachel E. Sachs, Nicholson Price, Patricia J. Zeitler

Articles

In several controversial drug approval decisions in recent years, the Food & Drug Administration (“FDA”) has publicly justified its decision partly on the ground that approving the drugs in question would support innovation in those fields going forward. To some observers, these arguments were surprising, as the Agency’s determination whether a drug is “safe” and “effective” does not seem to depend on whether its approval also supports innovation. But FDA’s use of these innovation arguments in drug approval decisions is just one example of the ways in which the Agency has come to make many innovation-related judgments as part of …

Brief Of A Former Federal Judge, Fair And Just Prosecution, 17 Law Professors, And 4 Domestic Violence Researchers And Advocates As Amici Curiae In Support Of Petitioner, Jamie Abrams

Amicus Briefs & Court Filings

While amici are not formally affiliated with each other and come from a variety of professional fields, they are all keenly aware of the pernicious effects of gender bias against female defendants in American courtrooms. Each is deeply familiar with the toll that gender bias exacts not only on the individual women whose interactions with the criminal legal system are tainted by it, but also on the quality, reliability, and fairness of the criminal legal system. Together they have a distinct interest in ensuring that inflammatory and prejudicial gendered stereotypes about how women should look, act, and comport themselves are …

Diversity And Inclusion Trainings As A Public Relations Imperative: Addressing The Faragher - Ellerth Test Via Interest-Convergence And Targeted Universalism, Mary Marston

American University Journal of Gender, Social Policy & the Law

This Article argues that courts must adopt a nuanced and culturally sensitive approach when addressing discrimination claims related to culturally and racially significant hairstyles. Specifically, it suggests incorporating immutable characteristics of racial and religious expression as a foundational standard in evaluating such cases. This approach aims to ensure equitable consideration in the adjudication of Title VII sexual harassment claims and Title VII racial discrimination claims.

This section addresses some of the different terminology used by members of the LGBTQ community to describe their gender identity, including the relatively well-known term “nonbinary” and continuing through to the less concrete term “queer.” Section II looks at the history of state action policing queer bodies and identities. It outlines statutes enacted to prevent individuals from hiding their identities and how such laws were used to target queer individuals. Section III discusses the case of Grimm v. Gloucester County School Boardand the two approaches …

The Very Interstate Nature Of The Internet? Establishing Uniform Requirements For Internet Transmissions Within Interstate And Foreign Commerce, Catherine Beal

American University Journal of Gender, Social Policy & the Law

This Comment argues that federal statutes, including the jurisdictional nexus of “transmission in interstate or foreign commerce,” should require evidence that a transmission actually traveled through interstate commerce to establish the required federal nexus. Part II of this article describes what threatening internet speech is, the development of the circuit split, and the statutory criteria at issue. Part III analyzes each side of the split and examines when statutory language permits an assumption of interstate or foreign transmission. Part III also proposes adopting a strict definition of “transmission in interstate and foreign commerce” for Internet-based speech and requiring evidence that …

Why Play? Exploring The Realities Of Play-Based Learning In Kindergarten, Sofia Josephine Steele

Honors Program Theses

By nature, children are curious and love to explore the world around them. Play is one way that children can fulfill that innate curiosity. Through play-based learning, educators can utilize that innate curiosity and wonder in children to create valuable learning experiences that will engage and teach them. This pedagogical approach is used in early childhood education to help children develop their academic, social, and emotional skills through appropriate learning experiences that consider their abilities and interests. However, in recent years, there has been a shift away from play-based learning in kindergarten classrooms. The reasoning behind this shift may be …

Efficient Synthesis Of Thiazole-Fused Bisnoralcohol Derivatives As Potential Therapeutic Agents, Subrata Roy, Hansa Raj Kc, Sanjay Adhikary, Alexander N. Erickson, Mohammad Abrar Alam

Chemistry Faculty Research and Publications

Thiazole derivatives are known for a wide range of therapeutic properties. Bisnoralcohol is an inexpensive natural product obtained by the biodegradation of sterols. This article describes an efficient synthesis of a library of thiazole-fused bisnoralcohol derivatives. These novel compounds have been studied for their antineoplastic and antibacterial properties, which led to the discovery of hit compounds with therapeutic potential. The antibacterial compound is noncytotoxic and nonhemolytic against cancer cell lines and sheep red blood cells, respectively. Several of the antineoplastic compounds showed activity against human cancer cell lines with growth inhibition at submicromolar concentration.

Screen Time And Problematic Behavior: Piloting A Family- Based Intervention, Naomi Morissette

PCOM Psychology Dissertations

School-aged children are increasingly growing up in a technology-driven society. The amount of time children spend engaged with screens is problematic, as is the subsequent impact on the development of their executive functioning skills. The current study investigated the feasibility of an online, asynchronous, family-based intervention to limit screen usage for elementary-aged children. It was hypothesized that removing screens from children’s bedrooms and one hour before bedtime was a feasible strategy to limit screen use and would result in positive behavior change, specifically regarding the ability to self-cue the use of executive skills. Additionally, it was hypothesized that an online …

Determinants Of Medical Cannabis Use For The Treatment Of Anxiety: A Qualitative Study, Catherine Blasi

PCOM Psychology Dissertations

Anxiety is a disorder characterized by feelings of tension, excessive fear, and physiological changes. Specific classes of anxiety disorders have been recognized, including social anxiety disorder, generalized anxiety disorder, agoraphobia, specific phobia, panic disorder, and separation anxiety disorder. Cannabis is the most commonly used federal substance in the U.S. In recent years, medical cannabis has been increasingly utilized as a treatment option following approval in many U.S. states. At present, no literature addresses explicitly why individuals with anxiety choose to utilize medical cannabis as a treatment option instead of other longstanding treatment options, including psychotherapy and medication. Therefore, the purpose …

The study used a case study research design to document the faculty's experiences discussing and reflecting on their practice and perceptions of …

Diversity Across Disciplines: Student Response To Dei Content In College Curricula, Angela Pettitt

Theses and Dissertations

Discussion and inclusion of diversity-related topics in higher education are often confined to specific courses designated as fulfilling a university-mandated diversity requirement such as courses in women's studies, Black history or literature, Eastern religions, among others. Mainstream general education courses in disciplines such as psychology, chemistry, or communications typically do not address diversity, equity, and inclusion (DEI) topics as part of the curriculum, even if individual textbooks, courses, or faculty work to improve such courses' pluralism. However, as the U.S. population becomes both more diverse and segregated, and as DEI initiatives come under fire from state legislators, students receive conflicting …
