Properties Of Left-Separated Spaces And Their Unions, Eric Scheidecker

Dissertations and Theses @ UNI

Left-separated spaces are topological spaces which can be well ordered such that every initial segment is closed. In this paper, we examine what topological properties imply left-separation, and under what circumstances left-separation is preserved by unions. We also introduce several known theorems regarding elementary submodels as they are one of the primary tools that we use. We prove that for a topological space X;

1. If X has a point-countable base, then X is left-separated if and only if X has closed intersection with any elementary submodel M such that X ∈ M.

2. If every elementary submodel …

An Experimental Study Of Non-Metallic Inclusions Precipitation And Its Effect On Impact Toughness Variations In Low Alloy Steel Subjected To Complex Deoxidation, Pavel Bizyukov

Dissertations and Theses @ UNI

A low level of non-metallic inclusions in steel is the key requirement in the concept of clean steel. Although the concept has received its name quite recently, it has been implemented at the large-scale steel mills for more than 40 years. Production of clean steel became possible due active development and adoption of the post-melting treatment of molten metal in the teeming ladle. Ladle metallurgy, an umbrella term for various methods of treatment, includes operations that cannot be performed during primary metallurgical processes such as melting in an electric arc, basic oxygen, or air induction furnace. Initially, the most common …

The Sum Is More Public Domain Than Its Parts: Us Copyright Protection For Works Of Applied Art Under Star Athletica's Imagination Test, Jane C. Ginsburg

Faculty Scholarship

In Star Athletica v. Varsity Brands, the Supreme Court granted certiorari to resolve confusion in the lower courts regarding the "separability" predicate to copyright protection of decorative features of useful articles. Adopting the Gordian imagery evoked by other appellate courts, the Sixth Circuit in Varsity Brands lamented "[c]ourts have twisted themselves into knots trying to create a test to effectively ascertain whether the artistic aspects of a useful article can be identified separately from and exist independently of the article's utilitarian function." Star Athletica involved the "surface decorations" of stripes, chevrons, and color blocks applied to cheerleader uniforms. While the …

Criminal Deterrence: A Review Of The Literature, Aaron Chalfin, Justin Mccrary

Faculty Scholarship

We review economics research regarding the effect of police, punishments, and work on crime, with a particular focus on papers from the last twenty years. Evidence in favor of deterrence effects is mixed. While there is considerable evidence that crime is responsive to police and to the existence of attractive legitimate labor-market opportunities, there is far less evidence that crime responds to the severity of criminal sanctions. We discuss fruitful directions for future work and implications for public policy.

Antitrust Via Rulemaking: Competition Catalysts, Tim Wu

Faculty Scholarship

In its March 26, 2016 issue, The Economist magazine announced that "America needs a giant dose of competition." Its study of industry concentration and profits suggested that, after decades of consolidation, competition had decreased across a broad range of the American economy. An April 2016 issue brief by the Council of Economic Advisors reached similar conclusions, stating that "competition appears to be declining" due to "increasing industry concentration, increasing rents accruing to a few firms, and lower levels of firm entry and labor market mobility."

The promotion of competition in the American economy is a task that has traditionally fallen …

If It Ain't Broke, Don't Fix It, Kathryn Judge

Faculty Scholarship

A prescription is only as good as the diagnosis on which it is based. This is just as true in finance as it is in medicine. And, in Hal Scott's assessment, the reforms adopted in the wake of the 2007-09 financial crisis ("Crisis") are based on a fundamental misunderstanding of the reasons for that crisis. The future is accordingly bleak.

Historical Gloss, Constitutional Conventions, And The Judicial Separation Of Powers, Curtis A. Bradley, Neil S. Siegel

Faculty Scholarship

Scholars have increasingly focused on the relevance of post-Founding historical practice to discern the separation of powers between Congress and the executive branch, and the Supreme Court has recently endorsed the relevance of such practice. Much less attention has been paid, however, to the relevance of historical practice to discerning the separation of powers between the political branches and the federal judiciary—what this Article calls the “judicial separation of powers.” As the Article explains, there are two ways that historical practice might be relevant to the judicial separation of powers. First, such practice might be invoked as an appeal to …

How International Is International Law: Remarks By Lori F. Damrosch, Lori Fisler Damrosch

Faculty Scholarship

Our moderator's questions begin with “in what sense is international law and in what sense isn't it universal?” and continue with whether international law may be “different in different places” and what the implications of such differences may be. I am here to defend the “universalist” perspective, as the immediate past president of the American Society of International Law and before that, editor-in-chief of the American Journal of International Law. Though both the Society and the Journal have “American” in their titles and our geographic headquarters is in the United States, the Society's mission statement commits us to pursue …

The Strange Life Of Stanley V. Illinois: A Case Study In Parent Representation And Law Reform, Joshua Gupta-Kagan

Faculty Scholarship

This Article helps describe the growth of parent representation through an analysis of Stanley v. Illinois — the foundational Supreme Court case that established parental fitness as the constitutional lynchpin of any child protection case. The Article begins with Stanley’s trial court litigation, which illustrates the importance of vigorous parental representation and an effort by the court to prevent Stanley from obtaining an attorney. It proceeds to analyze how family courts applied it (or not) in the years following the Supreme Court’s decision and what factors have led to a recent resurgence of Stanley’s fitness focus.

Despite Stanley …

Stanley V. Illinois'S Untold Story, Joshua Gupta-Kagan

Faculty Scholarship

Stanley v. Illinois is one of the Supreme Court’s more curious landmark cases. The holding is well known: the Due Process Clause both prohibits states from removing children from the care of unwed fathers simply because they are not married and requires states to provide all parents with a hearing on their fitness. By recognizing strong due process protections for parents’ rights, Stanley reaffirmed Lochner-era cases that had been in doubt and formed the foundation of modern constitutional family law. But Peter Stanley never raised due process arguments, so it has long been unclear how the Court reached this …

Introduction To Symposium On Unauthorized Military Interventions For The Public Good, Monica Hakimi

Faculty Scholarship

On April 6, 2017, the United States launched fifty-nine Tomahawk missiles against an air base in Syria, after evidence surfaced that Bashar Al-Assad’s regime had again used chemical weapons against its people. President Trump announced that the strikes were intended “to prevent and deter the spread and use of deadly chemical weapons.” But as of this Symposium’s publication, the United States has not articulated a formal legal justification for the strikes. Instead, it reportedly circulated a document that listed several case-specific considerations that, in its view, justified the use of force. Yet the global reaction was overwhelmingly positive. Many states …

Reply On The Work Of International Law, Monica Hakimi

Faculty Scholarship

Thanks to the Harvard International Law Journal for hosting a symposium on my Article and to the four respondents for their thoughtful contributions. In the Article, I distill and then criticize a prominent view about the role of international law in the global order. The view — what I call the “cooperation thesis” — is that international law serves to foster a particular kind of cooperation, specifically to help the participants achieve their common aims and curb their disputes. Lawyers who subscribe to this view of course appreciate that international law is, like all law, often contentious in operation. But …

The Work Of International Law, Monica Hakimi

Faculty Scholarship

This Article crystallizes and then critiques a prominent view about the role of international law in the global order. The view — what I call the “cooperation thesis” — is that international law serves to help global actors cooperate, specifically by: (1) curbing their disputes, and (2) promoting their shared goals. The cooperation thesis often appears as a positive account of international law; it purports to explain or describe what international law does. But it also has normative force; international law is widely depicted as dysfunctional when it does not satisfy the thesis. In particular, heated or intractable conflict is …

The Role Of National Courts At The Threshold Of Arbitration, George A. Bermann

Faculty Scholarship

There is a broad consensus that national courts of the arbitral seat have some kind of role to play during the pendency of an arbitration, though the exact contours of that role may differ from jurisdiction to jurisdiction. Similarly, it seems clear that national courts have a role to play on a post-award basis. While jurisdictions may vary as to the extent of control in annulment actions, the New York Convention brings a high degree of consensus over the role of courts in the recognition and enforcement of foreign awards, even though the Convention may receive different interpretations in different …

Tribute To Alfred Hill, Harold Edgar

Faculty Scholarship

Alfred Hill, a great legal scholar and one of Columbia’s treasures for nearly 50 years, died in 2015 at the age of 98. The Columbia Law Review honored him on his retirement from active teaching in 1991, but Al continued to write important work even into the twenty-first century.

The Strange Case Of Dr. Jekyll's Will: A Tale Of Testamentary Capacity, Stephen R. Alton

Faculty Scholarship

Robert Louis Stevenson’s classic novella, The Strange Case of Dr. Jekyll and Mr. Hyde, published in 1886, is the well-known tale of a respected scientist (Dr. Henry Jekyll) who transforms himself into an evil-doer (Mr. Edward Hyde). While the work raises issues of tort and criminal liability, this article analyzes the legal issues presented by one particular and crucial plot device that Stevenson employs—the last will of Dr. Jekyll. This will so obsesses Jekyll’s friend and solicitor, Gabriel John Utterson (through whose eyes the story unfolds), that he is impelled to seek the truth behind his friend’s relationship to Hyde. …

The Known Unknowns Of The Business Tax Reforms Proposed In The House Republican Blueprint, Michael J. Graetz

Faculty Scholarship

In 2002, referring to Iraq and its relationship to terrorism, Donald Rumsfeld declared "that there are known knowns, there are things we know we know. We also know that there are known-unknowns, that is to say we know there are some things that we do not know, but there are also unknown-unknowns – the ones that we don't know we don't know."

Localist Administrative Law, Nestor M. Davidson

Faculty Scholarship

To read the voluminous literature on administrative law is to inhabit a world focused almost exclusively on federal agencies. This myopic view, however, ignores the wide array of administrative bodies that make and implement policy at the local-government level. The administrative law that emerges from the vast subterranean regulatory state operating within cities, suburbs, towns, and counties has gone largely unexamined. Not only are scholars ignoring a key area of governance, but courts have similarly failed to develop an administrative jurisprudence that recognizes what is distinctive about local agencies. The underlying justifications for core administrative law doctrines at the federal …

A Guide To The Guide To The Republican Better Way Plan, Alex Raskolnikov

Faculty Scholarship

This special Issue of the Columbia Journal of Tax Law is bound to have both an immediate impact and a lasting significance. The immediate impact is assured because the sole focus of this Issue is the tax plan proposed by the Congressional Republicans as part of their broad reform agenda called A Better Way: Our Vision For A Confident America. As this Issue goes to print, the Better Way Plan (or the Plan for short) is being debated in the White House, on Capitol Hill, in the press, in academic circles, think tanks, the U.S. Chamber of Commerce, and …

Protean Statutory Interpretation In The Courts Of Appeals, James J. Brudney, Lawrence Baum

Faculty Scholarship

This Article is the first in-depth empirical and doctrinal analysis of differences in statutory interpretation between the courts of appeals and the Supreme Court. It is also among the first to anticipate how the Supreme Court’s interpretive approach may shift with the passing of Justice Scalia.

We begin by identifying factors that may contribute to interpretive divergence between the two judicial levels, based on their different institutional structures and operational realities. In doing so, we discuss normative implications that may follow from the prospect of such interpretive divergence. We then examine how three circuit courts have used dictionaries and legislative …

Influenza vaccines of H7N9 subtype are consistently less immunogenic in humans than vaccines developed for other subtypes. Although prior immunoinformatic analysis identified T-cell epitopes in H7 hemagglutinin (HA) which potentially enhance regulatory T cell response due to conservation with the human genome, the links between the T-cell epitopes and low immunogenicity of H7 HA remains unknown due to the lack of animal models reproducing the response observed in humans. Here, we utilized a humanized mouse model to recapitulate the low immunogenicity of H7 HA. Our analysis demonstrated that modification of a single H7 epitope by changing 3 amino acids so …

Serpentinization-Influenced Groundwater Harbors Extremely Low Diversity Microbial Communities Adapted To High Ph, Katrina I. Twing, William J. Brazelton, Michael D. Y. Kubo, Alex J. Hyer, Dawn Cardace, Tori M. Hoehler, Tom M. Mccollom, Matthew O. Schrenk

Geosciences Faculty Publications

Serpentinization is a widespread geochemical process associated with aqueous alteration of ultramafic rocks that produces abundant reductants (H₂ and CH₄) for life to exploit, but also potentially challenging conditions, including high pH, limited availability of terminal electron acceptors, and low concentrations of inorganic carbon. As a consequence, past studies of serpentinites have reported low cellular abundances and limited microbial diversity. Establishment of the Coast Range Ophiolite Microbial Observatory (California, U.S.A.) allowed a comparison of microbial communities and physicochemical parameters directly within serpentinization-influenced subsurface aquifers. Samples collected from seven wells were subjected to a range of analyses, including …
