Magnetic Flux Expulsion In Superconducting Radio-Frequency Niobium Cavities Made From Cold Worked Niobium, Bashu D. Khanal, S. Balachandran, S. Chetri, P. J. Lee, P. Dhakal

Physics Faculty Publications

Trapped residual magnetic field during the cooldown of superconducting radio frequency (SRF) cavities is one of the primary source of RF residual losses leading to lower quality factor. Historically, SRF cavities have been fabricated from high purity fine grain niobium with grain size ~50 - 100 μm as well as large grain with grain size of the order of few centimeters. Non-uniform recrystallization of fine-grain Nb cavities after the post fabrication heat treatment leads to higher flux trapping during cooldown, hence the lower quality factor. We fabricated two 1.3 GHz single cell cavities from cold-worked niobium from different vendors and …

Verification Dilemmas In Law And The Promise Of Zero-Knowledge Proofs, Kenneth A. Bamberger, Ron Canetti, Shafi Goldwasser, Evan J. Zimmerman

Faculty Scholarship

Individuals who wish to access a website or qualify for a loan are expected to expose personally identifying information, undermining their privacy and security. Firms share proprietary information in dealmaking negotiations which, if the deal fails, may be used by the negotiating partner for a competitive advantage. Regulators are expected to disclose their algorithmic tools to comply with public transparency and oversight requirements, a practice that risks rendering these tools circumventable and ineffective. Litigants might have to reveal trade secrets in court proceedings to prove a claim or defense. Such “verification dilemmas” — costly choices between opportunities that require the …

Legal Coding Beyond Capital?, Katharina Pistor

Faculty Scholarship

Capital, I argue in ‘The Code of Capital: How the Law Creates Wealth and Inequality’, is coded in law. Legal coding is a process that adapts and molds formal law over time, often without explicit ex ante sanctioning by a legislature or a court. Several characteristics of formal law make it susceptible to coding, including its inherent incompleteness, the strong endorsement for private autonomy, and decentralised access to a state’s consolidated means of coercion. Would a progressive European Code of Private Law (EPL-code), as proposed by Hesselink, alter any of this and what would it take to ensure that the …

Federalism And Equal Citizenship: The Constitutional Case For D.C. Statehood, Jessica Bulman-Pozen, Olatunde C.A. Johnson

Faculty Scholarship

As the question of D.C. statehood commands national attention, the legal discourse remains stilted. The constitutional question we should be debating is not whether statehood is permitted but whether it is required.

Commentators have been focusing on the wrong constitutional provisions. The Founding document and the Twenty-Third Amendment do not resolve D.C.’s status. The Reconstruction Amendments — and the principle of federated, equal citizenship they articulate — do. The Fourteenth Amendment’s Citizenship Clause, as glossed by subsequent amendments, not only establishes birthright national citizenship and decouples it from race and caste but also makes state citizenship a constitutive component of …

A Tale Of Two Civil Procedures, Pamela K. Bookman, Colleen F. Shanahan

Faculty Scholarship

In the United States, there are two kinds of courts: federal and state. Civil procedure classes and scholarship largely focus on federal courts but refer to and make certain assumptions about state courts. While this dichotomy makes sense when discussing some issues, for many aspects of procedure this breakdown can be misleading. Two different categories of courts are just as salient for understanding American civil justice: those that routinely include lawyers and those where lawyers are fundamentally absent.

This Essay urges civil procedure teachers and scholars to think about our courts as “lawyered” and “lawyerless.” Lawyered courts include federal courts …

Illiberalism And Administrative Government, Jeremy K. Kessler

Faculty Scholarship

Driven by the perception that liberal democracy is in a state of crisis across the developed world, political and legal commentators have taken to contrasting two alternatives: “illiberal democracy” (or populism) and “undemocratic liberalism” (or technocracy). According to the logic of this antinomy, once an erstwhile liberal-democratic nation-state becomes too populist, it is on the path toward illiberal democracy; once it becomes too technocratic, it is on the path toward undemocratic liberalism.

While the meanings of liberalism and democracy are historically and conceptually fraught, the contemporary discourse of liberal democratic crisis assumes a few minimal definitions. Within this discourse, liberalism …

Courts And Effective Governance, Mark Tushnet, Madhav Khosla

Faculty Scholarship

Governments are put in place to carry out policies. Effective governance means that they have the capacity to implement those policies. As Samuel Huntington observed, “[t]he most important political distinction among countries concerns not their form of government but their degree of government.” For our purposes, state capacity is the ability of a government-in-place to develop and implement policies that its leaders believe will improve national well-being. The capacity to govern includes having the required material resources, the personnel for whatever is necessary to deliver the policies to their beneficiaries, and a bureaucratic organization that enables high-level officials to implement …

Countering The New Election Subversion: The Democracy Principle And The Role Of State Courts, Jessica Bulman-Pozen, Miriam Seifter

Faculty Scholarship

Among the threats to American democracy, the most serious may also be the most banal: future elections will be compromised by quiet changes to the law. State legislators across the country have introduced bills that give them power to reject the will of voters. They have established sham audits and investigations. And they have created new criminal offenses that undermine professional election administration. While power-shifting legislation, audits, and criminal penalties advertise their fealty to law, they threaten the franchise and electoral integrity, as well as nonpartisan, expert election administration. Because of its ostensibly legal, even legalistic, character, however, the new …

Education Is Speech: Parental Free Speech In Education, Philip A. Hamburger

Faculty Scholarship

Education is speech. This simple point is profoundly important. Yet it rarely gets attention in the First Amendment and education scholarship.

Among the implications are those for public schools. All the states require parents to educate their minor children and at the same time offer parents educational support in the form of state schooling. States thereby press parents to take government educational speech in place of their own. Under both the federal and state speech guarantees, states cannot pressure parents, either directly or through conditions, to give up their own educational speech, let alone substitute state educational speech. This abridges …

Ending Cps Home Searches' Evasion Of The Fourth Amendment, Joshua Gupta-Kagan

Faculty Scholarship

Every year, Child Protective Service (CPS) agencies investigate about 3 million families around the country for alleged neglect or abuse of their children. Under agency policies, all of those millions of investigations include searches of families’ homes. CPS investigators knock on the door (usually unannounced), look in every room of the house, open kitchen cabinets, sometimes inspect children’s bodies, and generally look for any evidence of child maltreatment. Yet CPS agencies rarely seek a warrant, and typically act as if that is unnecessary. (P. 18 & n.86.)

The Essential Meaning Of The Rule Of Law, Thomas W. Merrill

Faculty Scholarship

We have heard much in recent times about the rule of law. Everyone seems to be in favor of it. Everyone seems to think that those with whom they strongly disagree are violating it. Let me remind you of a few examples.

President Obama, frustrated by Congress’s failure to adopt immigration reform, stated at a cabinet meeting that he still had a “pen and a phone.” He proceeded to announce a policy called DACA, short for Deferred Action for Childhood Arrivals, which effectively adopted a type of amnesty for some 700,000 persons who had arrived in the country as children …

Tributes To Family Law Scholars Who Helped Us Find Our Path, Ann Laquer Estin, Melissa Murray, June Carbone, Barbara A. Atwood, Paul M. Kurtz, J. Thomas Oldham, Bruce M. Smyth, Brian H. Bix, Elizabeth S. Scott, R.A. Lenhardt, Jessica Dixon Weaver, Solangel Maldonado, Sacha M. Coupet

Faculty Scholarship

At some point after the virus struck, I had the idea that it would be appropriate and interesting to ask a number of experienced family law teachers to write a tribute about a more senior family law scholar whose work inspired them when they were beginning their careers. I mentioned this idea to some other long-term members of the professoriate, and they agreed that this could be a good project.

So I reached out to some colleagues and asked them to participate. Many agreed to join the team. Some suggested other potential contributors, and some of these suggested faculty members …

New Democracy: Finding Hope In The Past And Heavy Lifting For The Future, Kate Andrias

Faculty Scholarship

Bill Novak has written a remarkable book that debunks the myth that the American state was weak and unconcerned with providing for social welfare until it was transformed by the extraordinary leadership of President Franklin Delano Roosevelt. He shows with compelling detail that the New Deal was not a magical or anomalous moment, but rather came about because of legal, institutional, socioeconomic, and democratic “heavy lifting” that occurred over the course of the preceding seventy years.

Adversarial Scrutiny Of Evidentiary Statistical Software, Rediet Abebe, Moritz Hardt, Angela Jin, John Miller, Ludwig Schmidt, Rebecca Wexler

Faculty Scholarship

The U.S. criminal legal system increasingly relies on software output to convict and incarcerate people. In a large number of cases each year, the government makes these consequential decisions based on evidence from statistical software — such as probabilistic genotyping, environmental audio detection and toolmark analysis tools — that the defense counsel cannot fully cross-examine or scrutinize. This undermines the commitments of the adversarial criminal legal system, which relies on the defense’s ability to probe and test the prosecution’s case to safeguard individual rights.

Responding to this need to adversarially scrutinize output from such software, we propose robust adversarial testing …

In Search Of Good Corporate Governance, Dorothy S. Lund

Faculty Scholarship

In this Forum Response, Dorothy Lund considers whether the “corporate governance gap” between large and small public companies is the product of harmful or beneficial forces, and in so doing, rejects the idea that there is a single governance framework that is optimal for all public companies.

Asset Managers As Regulators, Dorothy S. Lund

Faculty Scholarship

The conventional view of regulation is that it exists to constrain corporate activity that harms the public. But amid perceptions of government failure, many now call on corporations to tackle social problems themselves. And in this moment of dissatisfaction with government, powerful asset managers have stepped in to serve as regulators of last resort, adopting rules that bind corporate America on issues of great social importance, including climate change and workplace diversity. This Article describes this dynamic — where shareholders have become regulators — which has been made possible by the rise of institutional shareholding (and index investing in particular) …

The Future Of Board Time And Priorities, Janet Foutty, Eric L. Talley, Carey Oven, Erica Mitnick Klein, Maureen Bujno, Katherine Waldock, Molly Calkins, Lyssa Bantleon Little, Caroline Schoenecker

Faculty Scholarship

“Houston, we’ve had a problem.”

Popularized by the 1995 film Apollo 13, this one line signals a dramatic turning point in the story of the 1970 mission to land three people on the surface of the moon.

It recounts the pivotal moment when carefully laid plans for a 33-hour stay on the moon are about to go awry. The very purpose of the mission — two space walks, a series of geological surveys, and the placement of scientific instruments that would send data back to Earth for long after — is in jeopardy.

It is the moment when the playbook …

Coastal Wave Powered Reverse Osmosis System, Alexander Raymond Charest, Joeseph Daniel Camobreco, Tori Sweet, Sam Williams, Andrew Lepage, Devan Sack, Meagan Wiggin, Chelsea Kimball, Brendan Reagan

Honors Theses and Capstones

Part of the Marine Energy Collegiate Competition (MECC) is the optional Build and Test Challenge where teams are encouraged to build a portion of their proposed solution. After the conducted testing the laboratory results are compared to the simulated and calculated models. For the MECC the University of New Hampshire (UNH) team decided to use a wave energy converter to produce pressurized water. The pressurized water would be filtered through a reverse osmosis membrane to make it potable. Our system uses the power of the ocean waves to move a float up and down in heave motion. This motion drives …

A Collaborative Self-Study: Reflections On Convening A Sotl Community Of Practice, Rebecca Wilson-Mah Dr., Jo Axe Dr., Elizabeth Childs Dr., Doug Hamilton Dr., Sophia Palahicky Dr.

International Journal for the Scholarship of Teaching & Learning

Communities of practice (CoPs) can provide opportunities for diverse and inclusive groups to convene, share, collaborate, and support others. Using a self-study research approach combined with a visual research method, this study explores both scholarly and practice-based insights to describe the anticipated attributes of a high functioning CoP for the support of collaborative engagement in Scholarship of Teaching and Learning (SoTL). The following nine emergent attributes are identified: 1) Structures; (2) Social environments; (3) Diversity; (4) Knowledge, learning and ideas; (5) Support; (6) Shared leadership; (7) Risk; (8) Results and impact; and (9) Growth over time. This study contributes to …

Student Preferences In Using Affordable Learning Materials To Teach Research Methods Online, Phillip D. Grant, Elizabeth M. Pope

International Journal for the Scholarship of Teaching & Learning

This basic qualitative study assessed students’ perceptions of affordable learning materials in an asynchronous master’s level research methods course at a regional university. Students preferred instructor-created mini-lectures (45%) more than required readings (39%), supplementary items concerning a specific topic (7%), sample studies (5%), CITI training modules (3%), and continuing education materials (2%). We found that students tended to prefer material that offered foundational information about research methods. Students also preferred material that “translated” academic language. Students preferred materials that were compatible with their perceived learning style. Finally, students preferred materials that related research methods to their own professional practice.

Strategies To Improve Shrinkage Resistance Of Cement-Based Materials For Extrusion-Based 3d Printing, Kavya Vallurupalli

Doctoral Dissertations

"The main objective of this study is to develop new generation of shrinkage-resistant 3D printable mortar mixtures. To this end, the research work was carried out to: i) identify key material and processing parameters that affect printability; ii) investigate the influence of water-to-cement ratio, superplasticizer dosage, and welan gum content on mortar printability; iii) propose a “printability window” where rheological properties and desorptivity can secure successful printing; iv) investigate effect of shrinkage mitigation materials (expansive agent (EA), pre-saturated lightweight sand (LWS), superabsorbent polymers (SAP), and shrinkage reducing admixture) on printability and shrinkage performance of mortar; and v) evaluate the effect …

Theoretical Determination Of The Yield Curve For Unsaturated Soils, Sara Fayek

Doctoral Dissertations

"An important step to developing a good understanding of the behavior of unsaturated soils is to adopt a formal and simple constitutive framework and to conduct high-quality and short-time experiments. Barcelona Basic Model (BBM) was the first elastoplastic constitutive model for unsaturated soils. The yield curve, which separates the elastic region from the elastoplastic region, is an important aspect of constitutive modeling for unsaturated soils. Most concepts for unsaturated soils were developed based upon the results from suction-controlled triaxial (SCTX) tests. Though, the SCTX tests on unsaturated soils are costly, time-consuming, and laborious, and their results are questionable. This study …

The Contribution Of Positive Affect And Loneliness On Readiness And Self-Efficacy To Quit Smoking Among Spanish-Speaking Mexican American Smokers, Tatiana Londoño, John R. Moore, Zully C. Guerra, Nazanin M. Heydarian, Yessenia Castro

School of Social Work Faculty Publications

Background: The existing research on affective and interpersonal determinants of smoking cessation largely under-represents minority smokers, such as Latinos.

Objective: The current study examined associations between affective and interpersonal factors with intermediary smoking cessation variables among Mexican-American smokers (N = 290; 60% male).

Methods: Measures of positive and negative affect, social support, and loneliness were each examined for associations with measures of motivational readiness to quit smoking, and smoking abstinence self-efficacy. Significant predictors were entered into models simultaneously to examine their unique associations. Covariates included gender, age, and educational attainment.

Results: Negative affect (b = .68, SE b = …

Effect Of Connection State & Transport/Application Protocol On The Machine Learning Outlier Detection Of Network Intrusions, George Yuchi, Torrey J. Wagner, Paul Auclair, Brent T. Langhals

Faculty Publications

The majority of cyber infiltration & exfiltration intrusions leave a network footprint, and due to the multi-faceted nature of detecting network intrusions, it is often difficult to detect. In this work a Zeek-processed PCAP dataset containing the metadata of 36,667 network packets was modeled with several machine learning algorithms to classify normal vs. anomalous network activity. Principal component analysis with a 10% contamination factor was used to identify anomalous behavior. Models were created using recursive feature elimination on logistic regression and XGBClassifier algorithms, and also using Bayesian and bandit optimization of neural network hyperparameters. These models were trained on a …

Building Fierce Empathy, Binny Miller

Scholarly Articles in Law Reviews & Journals

In this Article I explore the process of building and sustaining empathy with clients in the context of representing juvenile lifers-- people convicted of serious crimes as children and sentenced to life or sentences that ensure that they spend most of their lives in prison--in a law school clinic. Before turning to my own lawyering experiences and those of my clinic students, I ground the discussion of empathy in the competing theories of Charles Ogletree and Abbe Smith about the value of empathic lawyering for public defenders. These theories, together with the contributions of other scholars, provide a springboard for …

Defending Democracy Through Law: The Establishment Of The Legal Service Of The European Parliment, Fernanda Giorgia Nicola Dr., Antonio Caiola

Scholarly Articles in Law Reviews & Journals

Democracy, as well as the rule of law, is one of the founding values of the European Union. With the recent rise of some authoritarian governments in Europe, scholars have focused primarily on the efforts led by the European Commission and the European Court of Justice (“ECJ”) to curb democratic backsliding. While European institutions have struggled defending the rule of law inside the Union through lawsuits and economic sanctions against those governments, the history of integration shows how the European Parliament (“EP”) led the efforts to cure the democratic deficit existing in the European institutional system. Since the end of …

Contracting For Process, David Snyder

Scholarly Articles in Law Reviews & Journals

This article introduces the concept of contracting for process and considers when it is likely to be the best contract design. Contracting for process is in widespread use, but it often goes unnoticed. Some characteristics of contracting for process suit it particularly well to situations of uncertainty, including the radical uncertainty that results from fundamental disruptions such as COVID-19. Parties can employ this design for both contracts made or renegotiated during a crisis and for contracts made in ordinary times. The concept articulated here, however, is not confined to contexts of uncertainty or complexity; it can be used to achieve …

Africana Legal Studies: A New Theoretical Approach To Law & Protocol, Angi Porter

Scholarly Articles in Law Reviews & Journals

INTRODUCTION: In 1743, a group of enslaved Africans from various estates in French colonial New Orleans gathered, held a musical ceremony sung in their native language, and discussed the actions and fate of a slaveholder named Corbin. Earlier, Corbin had threatened to shoot one of the enslaved Africans in this group, and Corbin’s brother then actually shot that person with a gun loaded with salt. Now, as the group of Africans gathered, they determined that Corbin had to die. Two months later, Corbin disappeared and was never found.
