Dimensions Of Parenting And Children’S Conduct Problems: The Importance Of Considering Children’S Callous–Unemotional Traits, Carolina Facci, Andrea Baroncelli, Paul J. Frick, Enrica Ciucci

Faculty Publications

Research has clearly indicated that the development of serious behavioral problems in children and adolescents is influenced by parenting. However, recent research has refined the role of parenting by showing the importance of distinguishing between different types of parenting and in considering the role of callous–unemotional traits (CU traits) and conduct problems (CP) of the children. In the current study, we advance this research by distinguishing between emotional (e.g., parental warmth; parental hostility) and behavioral (e.g., use of positive reinforcement; inconsistent discipline/harsh discipline) aspects of parenting and by considering the way parents respond to children’s emotions (i.e., coaching and dismissing). …

Squeezing Blood From Stones? A Comparative Analysis Of Tax Relief For Victim-Survivors In Australia And The United States, Christine Speidel, Leslie Book, Ann Kayis-Kumar

Faculty Publications

Women who leave abusive relationships generally do so with increased debt, reduced assets, insecure housing and longer-term economic insecurity. Most of these women will be experiencing economic abuse even after the relationship has ended, and many cite financial instability as a key factor driving them back into abusive relationships. So, it is imperative that the tax and transfer system helps rather than hinders (albeit inadvertently) this cohort of financially vulnerable taxpayers. However, this is not always the case, with victim-survivors of economic abuse often liable for tax debts incurred by former partners operating businesses in the victim-survivor's name.

A Theory Of Genetic Dimensions In The Law, Yaniv Heled, Liza Vertinsky, Ana Santos Rutschman

Faculty Publications

Since the biotechnology revolution of the 1970s, genetic science and genetic technology have captured the public imagination. They have become a centerpiece of how we understand ourselves, our relationship with other humans, other living beings, our environment, and—indeed—with the universe. Through this evolution of understanding, genetic phenomena have acquired many meanings, some rooted in objective reality and others subjective and dependent on individual perceptions and sentiments.

However, legal decision-making and policymaking have not kept pace and reflect only a partial understanding of the multiple dimensions of genetic phenomena, which are forced into narrowing legal pathways, neglecting vital interests. As the …

The Business Of Abortion: Access To Capital Post Dobbs, Itay Ravid, Jonathan Zandberg

Faculty Publications

Access to credit—that is, the ability to receive financial leverage that could help jump-start businesses—is one of the most significant barriers preventing millions of American women from opening new businesses. Congress has attempted to address this issue since the 1970s, with legislation like the Equal Credit Opportunity Act (ECOA). Nevertheless, studies continue to show a persistent gender gap in access to credit. Scholars have offered a host of explanations for this gap, focusing on both the supply and demand sides of the equation.

This Article contributes to this growing scholarly exploration by offering a new, overlooked explanation for this gap: …

Mobile devices (e.g., tablets and smartphones) have been rapidly integrated into the lives of children and have impacted howchildren engage with digital media. The portability of these devices allows for sporadic, on-demand interaction, reducing theaccuracy of self-report estimates of mobile device use. Passive sensing applications objectively monitor time spent on a givendevice but are unable to identify who is using the device, a significant limitation in child screen time research. Behavioralbiometric authentication, using embedded mobile device sensors to continuously authenticate users, could be applied toaddress this limitation. This study examined the preliminary accuracy of machine learning models trained on iPad …

Trophic Interactions In Microbiomes Influence Plant Host Population Size And Ecosystem Function, Jiaqi Tan, Na Wei, Martin M. Turcotte

Faculty Publications

Plant microbiomes that comprise diverse microorganisms, including prokaryotes, eukaryotes and viruses, are the key determinants of plant population dynamics and ecosystem function. Despite their importance, little is known about how species interactions (especially trophic interactions) between microbes from different domains modify the importance of microbiomes for plant hosts and ecosystems. Using the common duckweed Lemna minor, we experimentally examined the effects of predation (by bacterivorous protists) and parasitism (by bacteriophages) within microbiomes on plant population size and ecosystem phosphorus removal. Our results revealed that the addition of predators increased plant population size and phosphorus removal, whereas the addition of parasites …

Narrative Analysis In Individuals With Parkinson’S Disease Following Intensive Voice Treatment: Secondary Outcome Variables From A Randomized Controlled Trial, Amy E. Ramage, Kathryn J. Greenslade, Kaila Cote, Jessica N. Lee, Cynthia M. Fox, Angela Halpern, Lorraine O. Ramig

Faculty Publications

Communication is often impaired in individuals with Parkinson’s disease (PD), typically secondary to sensorimotor deficits impacting voice and speech. Language may also be diminished in PD, particularly for production and comprehension of verbs. Evidence exists that verb processing is influenced by motor system modulation suggesting that verb deficits in PD are underpinned by similarities in the neural representations of actions that span motor and semantic systems. Conversely, subtle differences in cognition in PD may explain difficulty in processing of complex syntactic forms, which increases cognitive demand and is linked to verb use. Here we investigated whether optimizing motor system support …

Police-Made Law, Brenner M. Fissell

Faculty Publications

This Article presents evidence that police are writing laws that they enforce. This newly discovered phenomenon compounds the existing understanding of police “making” law through the exercise of discretion. They make law in a far more direct way, functioning as quasi-legislators at the local level—identifying a social problem, drafting an offense to address it, and directly proposing their offense for enactment. The conduct targeted, and the reasons for doing so, are diverse. For example, in one city a police chief successfully criminalized public intoxication so that intoxicated people would go to jails instead of hospitals; in another, a chief pushed …

Perspective—Surface-Display Techniques In Electrochemical Biosensor Designs For Health Monitoring, Courtney J. Weber, Megan D. Whisonant, Olivia M. Clay, Olja Simoska

Faculty Publications

Enzymatic and microbial electrochemical biosensors integrate enzymes and microorganisms as biological recognition elements into the sensor design and functionality. Enzyme-based sensors offer high sensitivity and selectivity for target analyte detection. However, these have limited stability necessary for continuous analyte monitoring. Contrarily, microbe-based electrochemical sensors provide a means for continuous analyte sensing but are associated with challenges related to analyte selectivity in complex samples. To address these limitations, surface-display methods, which bind enzymes to microbial surfaces, enhance biosensor selectivity and sensitivity. This perspective outlines the application of surface-display techniques, offering a promising avenue for health monitoring.

Toxoplasma gondii is a parasitic infection that can be transmitted in utero, resulting in fetal chorioretinitis and other long-term neurological outcomes. If diagnosed early, pregnancy-safe chemotherapeutics can prevent vertical transmission. Unfortunately, diagnosis of acute, primary infection among pregnant women remains neglected, particularly in low-and-middle-income countries. Clinically actionable diagnosis is complex due to the commonality of infection during childhood and early adulthood which spawn long-last antibody titers and historically unreliable direct molecular diagnostics. The current study employed a cross-sectional T. gondii perinatal surveillance study using digital PCR, a next generation molecular diagnostic platform, and a maternal-fetal outcomes survey to ascertain …

White Matter Trajectories Over The Lifespan, Stefania Conte, Dabriel Zimmerman, John E. Richards

Acoustofluidic Scanning Fluorescence Nanoscopy With A Large Field Of View, Geonsoo Jin, Neil Upreti, Joseph Rich, Jianping Xia, Chenglong Zhao, Tony Jun Huang

Faculty Publications

Large-field nanoscale fluorescence imaging is invaluable for many applications, such as imaging subcellular structures, visualizing protein interactions, and high-resolution tissue imaging. Unfortunately, conventional fluorescence microscopy requires a trade-off between resolution and field of view due to the nature of the optics used to form the image. To overcome this barrier, we developed an acoustofluidic scanning fluorescence nanoscope that simultaneously achieves superior resolution, a large field of view, and strong fluorescent signals. The acoustofluidic scanning fluorescence nanoscope utilizes the superresolution capabilities of microspheres that are controlled by a programmable acoustofluidic device for rapid fluorescence enhancement and imaging. The acoustofluidic scanning fluorescence …
