Fostering Spatial Ability Development In And For Authentic Stem Learning, Caiwei Zhu, Chloe Oi-Ying Leung, Eleni Lagoudaki, Mariana Velho, Natalia Segura-Caballero, Dietsje Jolles, Gavin Duffy, Gunter Maresch, Marianna Pagkratidou, Remke Klapwijk

Articles

Empirical interdisciplinary research has explored the role of spatial ability in STEM learning and achievement. While most of this research indicates that fostering spatial thinking in educational contexts has the potential to positively impact students’ enrollment and performance in STEM subjects, there is less agreement on the best approach to do so. This article provides an overview of various types of effective spatial interventions and practices in formal or informal educational contexts, including targeted training of STEM-relevant spatial skills, spatialized curricula embedded in schools, integrated STEM practices addressing students’ use of spatial skills, and spatial activities in informal STEM education. …

Lightnet: A Novel Lightweight Convolutional Network For Brain Tumor Segmentation In Healthcare, Dongyuan Wu, Junyi Tao, Zhen Qin, Rao Asad Mumtaz, Jin Qin, Linfang Yu, Jane Courtney

Articles

Diagnosis, treatment planning, surveillance, and the monitoring of clinical trials for brain diseases all benefit greatly from neuroimaging-based tumor segmentation. Recently, Convolutional Neural Networks (CNNs) have demonstrated promising results in enhancing the efficiency of image-based brain tumor segmentation. Most current work on CNNs, however, is devoted to creating increasingly complicated convolution modules to improve performance, which in turn raises the computing cost of the model. This work proposes a simple and effective feed-forward CNN, LightNet (Light Network). Based on multi-path and multi-level, it replaces traditional convolutional methods with light operations, which reduces network parameters and redundant feature maps. In the …

Optical Properties Of Periodically And Aperiodically Nanostructured P-N Junctions, Z. Taliashvili, E Łusakowska E Łusakowska, S. Chusnutdinow, A. Tavkhelidze, L. Jangidze, S. Sikharulidze, Nima Ghadiri, Z. Chubinidze, R. Melkadze

Articles

Recently, semiconductor nanograting layers have been introduced and their optical properties have been studied. Spectroscopic ellipsometry has shown that nanograting significantly modifies the dielectric function of c-Si layers. Photoluminescence spectroscopy reveals the emergence of an emission band with a remarkable peak structure. It has been observed that nanograting also alters the electronic and magnetic properties. In this study, we investigate the quantum efficiency and spectral response of Si p-n junctions fabricated using subwavelength grating layers and aperiodically nanostructured layers.

Analysis Of Degradation Of Sb2se3 Thin Film Solar Cells Deploying A Time-Dependent Approach Linked With 1d-Amps Simulation, Ming-Lang Tseng, Malek Gassoumi, Nima Ghadiri

Articles

In this paper, we have developed a time-dependent model to study defect growth in the absorber layer of Sb2Se3 thin film solar cells. This model has been integrated with the AMPS-1D simulation platform to investigate the impact of increasing defect density at different positions within the Sb2Se3 layer on the electrical parameters of the solar cell. We adopted the Gloeckler standard model for thin films in AMPS to represent Sb2Se3 materials. The study focuses on tracking the degradation of device performance parameters as donor-like mid-gap states accumulate in the Sb2Se3 layer over time. We monitored the variation of key electrical …

An Evaluation Study On The Analysis Of People's Domestic Routines Based On Spatial, Temporal And Sequential Aspects, Aitor Arribas Velasco, John Mcgrory, Damon Berry

Articles

The concept of collecting data on people's domestic routines is not novel. However, the methods and processes used to decipher these raw data and transform them into useful and appropriate information (i.e., sequence, duration, and timing derived from monitoring domestic routines) have presented challenges and are the focus of numerous research groups. But how are the results of the decoded transposition received, interpreted and used by the various professionals (e.g., occupational therapists and architects) who consume the information? This paper describes the inclusive evaluation process undertaken, which involved a selected group of stakeholders including health carers, engineers and end-users (not …

Pattern And Polarization Diversity Multisector Annular Antenna For Iot Applications, Abel Zandamela, Nicola Marchetti, Max Ammann, Adam Narbudowicz, Wroclaw University Of Science And Technology

Articles

This work proposes a small pattern and polarization diversity multisector annular antenna with electrical size and profile of ka=1.2 and 0.018λ, respectively. The antenna is planar and comprises annular sectors that are fed using different ports to enable digital beamforming techniques, with efficiency and gain of up to 78%and 4.62 dBi, respectively. The cavity model analysis is used to describe the design concept and the antenna diversity. The proposed method can produce different polarization states (e.g., linearly and circularly polarized patterns) and pattern diversity characteristics covering the elevation plane. Owing to its small electrical size, low-profile and diversity properties, the …

Remote Justice & Domestic Violence: Process Pluralism Lessons From The Pandemic, Andrea K. Schneider, Heather Hlavka, Sameena Mulla, Erin Schubert, Aleksandra J. Snowden, Jennica Webster

Articles

Domestic violence procedures, like so many court processes around the world, were forced to go online and remote during the pandemic. The impact was dramatic-there were fewer restraining order petitions filed in the first place and an even lower amount granted. In short, domestic violence survivors, among the most vulnerable in our court system, were even more challenged in the last two years. Like many court systems, Milwaukee will never go back to being fully in-person for all procedures in conjunction with domestic violence. The evolving hybrid choices could provide additional access to justice, or these processes could create additional …

Bringing The Past To Life: Co-Creating Tourism Experiences In Historic House Tourist Attractions, Jacqui Doyle, Felicity Kelliher

Articles

This ethnographic study concentrates on the co-creation of experiential value between the tourist and tour guide in a single historic tourism site; Huntingdon Castle, Ireland. Built upon the principles of service dominant logic, the research explores how storytelling acts as an engagement platform and value enhancing strategic resource. In doing so, it impels the value co-creation journey and shapes the tourist’s experience. Observation is coupled with qualitative interviews to capture the dual perspective of both guides and tourists. Findings exhibit the co-creation process through the performance of stories; how and when people derive pleasure (value); the influencing aspects of the …

Structural And Solution Speciation Studies On Selected [Cu(Nn)(Oo)] Complexes And An Investigation Of Their Biomimetic Activity, Ros Generation And Their Cytotoxicity In Normoxic, Hypoxic And Anoxic Environments In Mcf-7 Breast Cancer-Derived Cells, Hollie Jenkins

Articles

Reactive oxygen species(ROS) generation with subsequent DNA damage is one of the principle mechanisms of action assigned to copper-based anticancer complexes. The efficacy of this type of chemotherapeutic may be reduced in the low oxygen environment of tumours. In this study the cytotoxicity of three complexes, [Cu(dips)(phen)] (1), [Cu(ph)(phen)]·2H2O (2) and [Cu(ph)(bpy)]·H2O (3) (disp: 3,5-diisopropylsalicylate, phen: 1,10- phenanthroline, ph: phthalate, bpy: 2,2′-bipyridyl) were assessed for anticancer activity in the breast-cancer derived MCF-7 line under normoxic, hypoxic and anoxic conditions. In an immortalised keratinocyte HaCaT cell line, the cytotoxicity of complexes 2 and 3 was significantly reduced under both normoxic and …

Peptidases Are Potential Targets Of Copper(Ii)-1,10-Phenanthroline-5,6-Dione Complex, A Promising And Potent New Drug Against Trichomonas Vaginalis, Graziela Vargas Rigo, Fernanda Gomes Cardoso, Matheus Mendonca Pereira, Michael Devereux, Malachy Mccann, Andre L.S. Santos, Tiana Tasca

Articles

Trichomonas vaginalis is responsible for 156 million new cases per year worldwide. When present asymptomatically, the parasite can lead to serious complications, such as development of cervical and prostate cancer. As infection increases the acquisition and transmission of HIV, the control of trichomoniasis represents an important niche for the discovery and development of new antiparasitic molecules. This urogenital parasite synthesizes several molecules that allow the establishment and pathogenesis of infection. Among them, peptidases occupy key roles as virulence factors, and the inhibition of these enzymes has become an important mechanism for modulating pathogenesis. Based on these premises, our group recently …

Comprehensive Genomic Characterization Of Cronobacter Sakazakii Isolates From Infant Formula Processing Facilities Using Whole-Genome Sequencing, Zeinab E.Mousavi, Leonard Koolman, Guerrino Macori, Séamus Fanning, Francis Butler, University College Dublin

Articles

Cronobacter sakazakii is an opportunistic pathogen linked to outbreaks in powdered infant formula (PIF), primarily causing meningitis and necrotizing enterocolitis. Whole-genome sequencing (WGS) was used to characterize 18 C. sakazakii strains isolated from PIF (powdered infant formula) manufacturing plants (2011–2015). Sequence Type (ST) 1 was identified as the dominant sequence type, and all isolates carried virulence genes for chemotaxis, flagellar motion, and heat shock proteins. Multiple antibiotic resistance genes were detected, with all isolates exhibiting resistance to Cephalosporins and Tetracycline. A significant correlation existed between genotypic and phenotypic antibiotic resistance. The plasmid Col(pHAD28) was identified in the isolates recovered from …

Taxes, Administrative Law, And Agency Expertise: Questioning The Orthodoxy, Scott Schumacher

Articles

One of the foundations of administrative law is that federal agencies and their employees are experts in their respective fields. In addition, the many judgments and decisions made by these experts are based on a thorough record after extensive factfinding. As a result, so the theory goes, courts, particularly courts of general jurisdiction like the United States District Courts, should give deference to the determinations made by these experts. But what if the facts underpinning this foundation are not true in all cases? Should courts nevertheless provide deference to decisions by agencies when it is evident that an agency's determinations …

Due Process Deportations, Angelica Chazaro

Articles

Should pro-immigrant advocates pursue federally funded counsel for all immigrants facing deportation? For most pro-immigrant advocates and scholars, the answer is self-evident: More lawyers for immigrants would mean more justice for immigrants, and thus, the federal government should fund such lawyers. Moreover, the argument goes, federally funded counsel for immigrants would improve due process and fairness, as well as make immigration enforcement more efficient. This Article argues the opposite: Federally funded counsel is the wrong goal. The majority of expulsions of immigrants now happen outside immigration courts— and thus are impervious to immigration lawyering. Even for those who make it …

I Owe My Teaching Career To Peter Henning, David A. Moran

Articles

In the late 1990s, I was very happily working as an appellate public defender in Detroit when the then-dean of Wayne State University Law School, Jim Robinson, contacted me to ask if I could teach a section of Criminal Procedure at night. Joe Grano, who had taught at Wayne for many years, had fallen ill, and so a replacement was needed. Dean Robinson was a close friend of Ralph Guy, the judge for whom I had clerked some years earlier, and Judge Guy had recommended me. I accepted the offer.

Even though I was just a lowly adjunct scheduled to …

Feedback Loops: E-D-I-T (Continued), Patrick Barry

Articles

In the "Feedback Loops" column back in March, we introduced the "E-D-I-T" framework:

• Find something to Eliminate
• Find something to Decrease
• Find something to Increase
• Find something to Try

This new column will discuss each category more in depth.

Dethroning Langdell, Beth H. Wilensky

Articles

I come not to bury the case method. I come merely to dethrone it. While the case method’s monopolistic hold on the law school classroom has loosened somewhat in recent years, it is still the dominant approach to pedagogy in many law school classrooms—and especially in the first-year law student experience. That is also true of the case method’s traditional pedagogical partners, the Socratic method and the cold call: their dominance has declined somewhat, even while they still have remarkable staying power.

This Essay identifies one fault with our continued acquiescence to these pedagogical mainstays of law school classrooms: it …

The Utpr And The Credits, Reuven S. Avi-Yonah

Articles

Critics of the UTPR (formerly known as the undertaxed payments rule) of the G-20/0ECD/ inclusive framework base erosion and profit shifting project's pillar 2 have focused on the potential impact of the top- up tax on U.S. environmental credits enacted in the Inflation Reduction Act(IRA, P.L.11 7-169) and on credits to encourage domestic chip manufacturing in the Creating Helpful Incentives to Produce Semiconductors and Science Act (the CHIPS Act, P .L. 117-167). They argue that Congress's ability to effectively implement its chosen policy goals is undermined because the UTPR - when applied to other parts of U.S. multinational enterprises - …

Pillar 2 And The Credits., Reuven S. Avi-Yonah

Articles

The international tax provisions of the Build Back Better Act (BBB) passed by the House of Representatives represent a reasonable compromise. They are consistent with the OECD’s Pillar Two statement, and they represent a significant move toward the implementation of the single tax principle (STP). In what follows, we will discuss the proposed changes and how they fit in with the new international tax regime (ITR). We will also address the possible interactions with the ITR if BBB is not enacted.

Antitrust Concerns Vis-A-Vis Disruptive Innovation – Takeaways For Competition Commission Of India, Sudhanshu Kumar, Garima Gupta

Articles

In the era of innovation, market dynamics have evolved demanding a more nuanced analysis of market competition. Innovation in digital economy does promise new products and services but it can be an amiable reality only if it is directed towards ensuring consumer welfare and a free markets space for players. Since digital markets attract innovators and disruptors, it is important for antitrust regulators to differentiate between efforts directed towards value-creation and ones aimed at destroying or impeding the same. This paper aims at theorizing around the idea of ‘disruptive innovation’ and its implications for competition policy for India. The paper …

Book Review L Boats In A Storm: Law, Migration, And Decolonization In South And Southeast Asia, 1942–1962 By Kalyani Ramnath (Stanford University Press 2023), Anwesha Ghosh

Articles

Kalyani Ramnath’s Boats in a Storm undertakes the formidable task of retelling the histories of decolonisation in India, Burma, Malaya, and Ceylon using characters who would rarely fit the description of conventional historical actors. Ramnath departs from the rich political and diplomatic histories that celebrate the independence of nation states from the yoke of imperial rule. Instead, she focuses on the ways in which these states, with their newly re-instituted legislative, juridical, and bureaucratic regimes, wreaked havoc on the lives of itinerant migrants who straddled between ‘homes’ and places of work across the Bay of Bengal and eastern Indian Ocean …

The Early Years Of Congress’S Anti-Removal Power, Aaron Nielson, Christopher J. Walker

Articles

Judges and scholars have long debated whether the Constitution provides the President with a power to remove executive officials. The Constitution, however, undoubtedly gives Congress tools to discourage the President’s use of such power. Perhaps most notably, the Appointments Clause makes it more difficult for the President to remove principal officers—even those whose views are out of the step with the President’s—because the President cannot know whether the Senate will consent to a preferred replacement. This is an example of what we dub Congress’s anti-removal power: Even if the President can remove, a motivated Congress can discourage the President’s use …

Public Law Litigation And Electoral Time, Zachary D. Clopton, Katherine Shaw

Articles

Public law litigation is often politics by other means. Yet scholars and practitioners have failed to appreciate how public law litigation intersects with an important aspect of politics-electoral time. This Essay identifies three temporal dimensions of public law litigation. First, the electoral time of government litigants-measured by the fixed terms of state and federal executive officials-may affect their conduct in litigation, such as when they engage in midnight litigation in the run-up to and aftermath of their election. Second, the electoral time of state courts-measured by the fixed terms of state judges-creates openings for strategic behavior among litigants (both public …

Commercially Reasonable Sales In The 21st Century, David G. Carlson

Articles

It has been over 20 years since the 2000 amendments profoundly amended the foreclosure procedures in Article 9 of the UCC. This article reviews how the amendments have fared in the case law since then.

Title Theft, Stewart E. Sterk

Articles

Real property owners across the country have been targeted by scammers who prepare deeds purporting to convey title to property the scammers do not own. Sometimes, the true owners are entirely unaware of these bogus transfers. In other instances, the scammers use misrepresentation to induce unsophisticated owners to sign documents they do not understand. Property doctrine protects owners against forgery and fraud—the primary vehicles scammers use in their efforts to transfer title. Owners enjoy protection not only against the scammers themselves, but generally against unsuspecting purchasers to whom the scammers transfer purported title. Recovery of title, however, involves costs and …

Concluding Remarks By Conference Co-Organizer, Richard H. Weisberg

Articles

This Article represents the concluding remarks made by Professor Richard H. Weisberg at "Disarmed, Distracted, Disconnected & Distressed," a conference on Modern Legal Education and the Unmaking of American Lawyers, hosted by the University of Pittsburgh School of Law and the Law & Humanities Institute, April 20-April 23, 2023.

Constitutional Review Of Federal Tax Legislation, Reuven S. Avi-Yonah, Yoseph M. Edrey

Articles

What does the Constitution mean when it says that “The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States” (U.S. Const. Article I, Section 8, Clause 1)?

The definition of “tax” for constitutional purposes has become important considering the Supreme Court’s 2012 decision in National Federation of Independent Business v. Sebelius (“NFIB”), in which Chief Justice Roberts for the Court upheld the constitutionality of the individual mandate of the Patient Protection and Affordable Care Act (“ACA”) under the taxing …

Hierarchy, Race & Gender In Legal Scholarly Networks, Nicholson W. Price, Keerthana Nunna, Jonathan Tietz

Articles

A potent myth of legal academic scholarship is that it is mostly meritocratic and mostly solitary. Reality is more complicated. In this Article, we plumb the networks of knowledge co-production in legal academia by analyzing the star footnotes that appear at the beginning of most law review articles. Acknowledgments paint a rich picture of both the currency of scholarly credit and the relationships among scholars. Building on others’ prior work characterizing the potent impact of hierarchy, race, and gender in legal academia more generally, we examine the patterns of scholarly networks and probe the effects of those factors. The landscape …

Résumé Review: Breadth And Depth, Patrick Barry

Articles

Nobody is born knowing how to craft an effective résumé. But because the document can play a major role in a young lawyer’s career, I often talk with law students and new attorneys about how they might revise the versions they send out to potential employers. I usually frame my advice by telling them about a concept that can give their resumes a helpful organizing structure: being “T-shaped.”

What Would Surrey Say? The Long Reach Of Stanley S. Surrey, Reuven Avi-Yonah, Nir Fishbien

Articles

Stanley S. Surrey died in 1984, two years before the enactment of the Tax Reform Act of 1986, which gave us the Internal Revenue Code of 1986 as amended. Historians have recently discovered Surrey’s work through his memoirs, published in 2022, and several articles based on the memoir and on the unpublished Surrey papers at Harvard Law School. There is no doubt that Surrey was a towering historical figure during his “Half-Century with the Internal Revenue Code.” As his protégé Donald Lubick, who served as Assistant Secretary for Tax Policy in both the Carter and the Clinton Administrations, stated, Surrey …

Why Criminal Defendants Cooperate: The Defense Attorney's Perspective, Jessica A. Roth, Anna D. Vaynman, Steven D. Penrod

Articles

Cooperation is at the heart of most complex federal criminal cases, with profound ramifications for who can be brought to justice and for the fate of those who decide to cooperate. But despite the significance of cooperation, scholars have yet to explore exactly how individuals confronted with the decision whether to pursue cooperation with prosecutors make that choice. This Article—the first empirical study of the defense experience of cooperation—begins to address that gap. The Article reports the results of a survey completed by 146 criminal defense attorneys in three federal districts: the Southern District of New York, the Eastern District …
