Rigidity Analysis Of Protein Biological Assemblies And Periodic Crystal Structures, Filip Jagodzinski, Pamela Clark, Jessica Grant, Tiffany Liu, Samantha Monastra, Ileana Streinu

Computer Science: Faculty Publications

Background: We initiate in silico rigidity-theoretical studies of biological assemblies and small crystals for protein structures. The goal is to determine if, and how, the interactions among neighboring cells and subchains affect the flexibility of a molecule in its crystallized state. We use experimental X-ray crystallography data from the Protein Data Bank (PDB). The analysis relies on an effcient graph-based algorithm. Computational experiments were performed using new protein rigidity analysis tools available in the new release of our KINARI-Web server http:// kinari.cs.umass.edu. Results: We provide two types of results: on biological assemblies and on crystals. We found that when only …

Towards Accurate Modeling Of Noncovalent Interactions For Protein Rigidity Analysis, Naomi Fox, Ileana Streinu

Computer Science: Faculty Publications

Background: Protein rigidity analysis is an efficient computational method for extracting flexibility information from static, X-ray crystallography protein data. Atoms and bonds are modeled as a mechanical structure and analyzed with a fast graph-based algorithm, producing a decomposition of the flexible molecule into interconnected rigid clusters. The result depends critically on noncovalent atomic interactions, primarily on how hydrogen bonds and hydrophobic interactions are computed and modeled. Ongoing research points to the stringent need for benchmarking rigidity analysis software systems, towards the goal of increasing their accuracy and validating their results, either against each other and against biologically relevant (functional) parameters. …

Governing The Post-Socialist Transitional Commons: A Case From Rural China, Shitong Qiao

Faculty Scholarship

When the collective declines, who manages the collective-owned land? When the socialist state fails, who possesses the state-owned river? This Article concerns the governance of land and natural resources that are still owned by collectives or the state in rural China. No effective community governance has evolved in rural China to fill the authority vacuum left by the dissolution of the people’s commune system. As a result, such land and natural resources have become real commons. In describing these I use the term “transitional commons” to indicate both the crucial influence of the transitional political legal environment in their emergence …

Predicting Application Performance Using Supervised Learning On Communication Features, Nikhil Jain, Abhinav Bhatele, Michael P. Robson, Todd Gamblin, Laxmikant V. Kale

Computer Science: Faculty Publications

Task mapping on torus networks has traditionally focused on either reducing the maximum dilation or average number of hops per byte for messages in an application. These metrics make simplified assumptions about the cause of network congestion, and do not provide accurate correlation with execution time. Hence, these metrics cannot be used to reasonably predict or compare application performance for different mappings. In this paper, we attempt to model the performance of an application using communication data, such as the communication graph and network hardware counters. We use supervised learning algorithms, such as randomized decision trees, to correlate performance with …

Authentication Of Social Media Evidence, Paul W. Grimm, Lisa Yurwit Bergstrom, Melissa M. O'Toole-Loureiro

Faculty Scholarship

The authentication of social media evidence has become a prevalent issue in litigation today, creating much confusion and disarray for attorneys and judges. By exploring the current inconsistencies among courts' decisions, this Article demonstrates the importance of the interplay between Federal Rules of Evidence 901, 104(a), 104(b), and 401-all essential rules for determining the admissibility and authentication of social media evidence. Most importantly, this Article concludes by offering valuable and practical suggestions for attorneys to authenticate social media evidence successfully.

The Crucial But (Potentially) Precarious Position Of The Chief Compliance Officer, Deborah A. Demott

Faculty Scholarship

This Article, written for a symposium on compliance issues in financial-services firms, focuses on the role of the chief compliance officer (“CCO”). Contrasting the position with that held by a firm’s general counsel or Chief Legal Officer (CLO), the article argues that a CCO’s position holds distinct challenges. Additionally, although internal compliance systems and personnel may be characterized as functional substitutes for external regulation, assessing the strengths and weaknesses of internal compliance requires a willingness to look deep within firms. The article argues that the law and regulation may enhance firms’ incentives to invest in effective internal compliance but may …

The Nagoya Protocol And Synthetic Biology Research: A Look At The Potential Impacts, Margo A. Bagley, Arti K. Rai

Faculty Scholarship

This report, prepared for the Synthetic Biology Project at the Woodrow Wilson International Center for Scholars, analyzes the 2010 Nagoya Protocol to the Convention on Biological Diversity and how it may affect U.S. researchers working in the field of synthetic biology. The objective of the Protocol is to provide a transparent framework for the acquisition and sharing of genetic resources on fair and equitable terms that facilitate the conservation of biological diversity and associated traditional knowledge. The report finds significant uncertainty surrounding the temporal scope of the Agreement as well as the types of genetic material that will be covered …

A General Defense Of Erie Railroad Co. V. Tompkins, Ernest A. Young

Faculty Scholarship

Erie Railroad Co. v. Tompkins was the most important federalism decision of the Twentieth Century. Justice Brandeis’s opinion for the Court stated unequivocally that “[e]xcept in matters governed by the Federal Constitution or by acts of Congress, the law to be applied in any case is the law of the state. . . . There is no federal general common law.” Seventy-five years later, however, Erie finds itself under siege. Critics have claimed that it is “bereft of serious intellectual or constitutional support” (Michael Greve), based on a “myth” that must be “repressed” (Craig Green), and even “the worst decision …

Firearm Localism, Joseph Blocher

Faculty Scholarship

Second Amendment doctrine is largely becoming a line-drawing exercise, as courts try to determine which “Arms” are constitutionally protected, which “people” are permitted to keep and bear them, and in which ways those arms and people can be regulated. But the developing legal regime has yet to account for one potentially significant set of lines: the city limits themselves. In rural areas, gun crime and gun control are relatively rare, and gun culture is strong. In cities, by contrast, rates of violent gun crime are comparatively high, and opportunities for recreational gun use are scarce. And from colonial Boston to …

Regulating Ex Post: How Law Can Address The Inevitability Of Financial Failure, Iman Anabtawi, Steven L. Schwarcz

Faculty Scholarship

Unlike many other areas of regulation, financial regulation operates in the context of a complex interdependent system. The interconnections among firms, markets, and legal rules have implications for financial regulatory policy, especially the choice between ex ante regulation aimed at preventing financial failure and ex post regulation aimed at responding to that failure. Regulatory theory has paid relatively little attention to this distinction. Were regulation to consist solely of duty-imposing norms, such neglect might be defensible. In the context of a system, however, regulation can also take the form of interventions aimed at mitigating the potentially systemic consequences of a …

Biometric Id Cybersurveillance, Margaret Hu

Faculty Scholarship

The implementation of a universal digitalized biometric ID system risks normalizing and integrating mass cybersurveillance into the daily lives of ordinary citizens. ID documents such as driver’s licenses in some states and all U.S. passports are now implanted with radio frequency identification (RFID) technology. In recent proposals, Congress has considered implementing a digitalized biometric identification card—such as a biometric-based, “high-tech” Social Security Card—which may eventually lead to the development of a universal multimodal biometric database (e.g., the collection of the digital photos, fingerprints, iris scans, and/or DNA of all citizens and noncitizens). Such “hightech” IDs, once merged with GPS-RFID tracking …

The Story Of Ewing: Three Strikes Laws And The Limits Of The Eighth Amendment Proportionality Review, Sara Sun Beale

Faculty Scholarship

In 1994 California enacted the nation's harshest "three strikes" law. Under this law, any felony can serve as a third strike, and conviction of a third strike requires a mandatory prison sentence of 25 years to life. In Ewing v. California, 538 U.S. 11 (2003), the Supreme Court held that sending a drug addict who shoplifted three golf clubs to prison for 25 years to life under the three strikes law did not violate the cruel and unusual punishment clause of the Eighth Amendment. The chapter for the forthcoming Criminal Law Stories tells the story of the Ewing case, describing …

How Markets Work: The Lawyer’S Version, Mitu Gulati, W. Mark C. Weidemaier

Faculty Scholarship

In this article, we combine two sources of data to shed light on the nature of transactional legal work. The first consists of stories about contracts that circulate widely among elite transactional lawyers. Surprisingly, the stories portray lawyers as ineffective market actors who are uninterested in designing superior contracts, who follow rather than lead industry standards, and who depend on governments and other outside actors to spur innovation and correct mistakes. We juxtapose these stories against a dataset of sovereign bond contracts produced by these same lawyers. While the stories suggest that lawyers do not compete or design innovative contracts, …

Collective Action Clauses For The Eurozone, Michael Bradley, Mitu Gulati

Faculty Scholarship

One of the primary policy initiatives instituted in response to the Eurozone sovereign debt crisis is a requirement that all Eurozone sovereign bonds issued after January 1 2013 include provisions referred to as Collective Action Clauses or CACs. These CACs allow for a super-majority of creditors to impose restructuring terms on minority holdouts. This article assesses the likely effect of this proposal on the borrowing costs of sovereign debtors. Contrary to much of the literature, we find that the presence of CACs leads to a lower cost of capital, especially for below-investment grade bonds

Happiness Surveys And Public Policy: What’S The Use?, Matthew D. Adler

Faculty Scholarship

This Article provides a comprehensive, critical overview of proposals to use happiness surveys for steering public policy. Happiness or “subjective well-being” surveys ask individuals to rate their present happiness, life-satisfaction, affective state, etc. A massive literature now engages in such surveys or correlates survey responses with individual attributes. And, increasingly, scholars argue for the policy relevance of happiness data: in particular, as a basis for calculating aggregates such as “gross national happiness,” or for calculating monetary equivalents for non-market goods based on coefficients in a happiness equation.

But is individual well-being equivalent to happiness? The happiness literature tends to blur …

Legitimacy And Lawmaking: A Tale Of Three International Courts, Laurence R. Helfer, Karen J. Alter

Faculty Scholarship

This article explores the relationship between the legitimacy of international courts and expansive judicial lawmaking. We compare lawmaking by three regional integration courts — the European Court of Justice (ECJ), the Andean Tribunal of Justice (ATJ), and the ECOWAS Community Court of Justice (ECCJ). These courts have similar jurisdictional grants and access rules, yet each has behaved in a strikingly different way when faced with opportunities to engage in expansive judicial lawmaking. The ECJ is the most activist, but its audacious legal doctrines have been assimilated as part of the court’s legitimate authority. The ATJ and ECOWAS have been more …

Narrative, Truth, And Trial, Lisa Kern Griffin

Faculty Scholarship

This Article critically evaluates the relationship between constructing narratives and achieving factual accuracy at trials. The story model of adjudication— according to which jurors process testimony by organizing it into competing narratives—has gained wide acceptance in the descriptive work of social scientists and currency in the courtroom, but it has received little close attention from legal theorists. The Article begins with a discussion of the meaning of narrative and its function at trial. It argues that the story model is incomplete, and that “legal truth” emerges from a hybrid of narrative and other means of inquiry. As a result, trials …

Citizens’ Perspectives Of Access To The Decision Making Process And Community Improvement As Determinants Of Brownfields Redevelopment Success, Shevon Jean Letang

Theses, Dissertations and Culminating Projects

Brownfields redevelopment is acclaimed as a successful program that has revitalized struggling urban communities and returned unproductive, underutilized, and abandoned industrial and commercial properties to municipalities’ tax rolls. Despite a major brownfields' redevelopment goal being to improve the communities and their citizens' quality of life, to date, the program has not been evaluated from the mainstreams' perspective as to its impact on their neighborhoods and their quality of life. A survey of 129 citizens from urban, suburban and exsuburban municipalities in Passaic County New Jersey sought to evaluate the social outcomes of three redeveloped projects from the affected mainstreams' perspective. …

Corporate Social Responsibility And The Gold Mining Industry : The Ghana Experience, Aimann Sadik

Theses, Dissertations and Culminating Projects

In 2012, the price of gold is sky rocketing due to strong demand and tight supply. Investors have revived their interest in gold investments at the expense of financial assets such as bonds and equities because of the current financial market turbulence. In addition, the trend in price has been fuelled by the strategic reserve holdings decisions by the central banks of advanced western economies to halt the sale of their gold reserves while that of emerging markets are acquiring gold holdings to protect their wealth during a period of global financial crisis. The supply of gold has not responded …

Metaphysical Dependence And Set Theory, John Wigglesworth

Dissertations, Theses, and Capstone Projects

In this dissertation, I articulate and defend a counterfactual analysis of metaphysical dependence. It is natural to think that one thing x depends on another thing y if had y not existed, then x wouldn't have existed either. But counterfactual analyses of metaphysical dependence are often rejected in the current literature. They are rejected because straightforward counterfactual analyses fail to accurately capture dependence relations between objects that exist necessarily, like mathematical objects. For example, it is taken as given that sets metaphysically depend on their members, while members do not metaphysically depend on the sets they belong to. The set …

The Lived Experiences Of Transition To Adult Healthcare In Young Adults With Cerebral Palsy, Ellen Mclaughlin Carroll

Dissertations, Theses, and Capstone Projects

Background: Health Care Transition (HCT) describes the purposeful, planned movement of adolescents from child to adult-orientated care. The purpose of this phenomenological study is to uncover the meaning of transition to adult centered care as experienced by Young Adults with Cerebral Palsy (YA-CP) through the research question: What are the lived experiences of young adults with cerebral palsy transitioning from pediatric to adult healthcare?

Method: 6 females and 3 males, aged 19 -25 years of age, who identified as carrying the diagnosis of cerebral palsy without cognitive impairment were interviewed. Giorgi's (1985) method for analysis of phenomenology was the framework …

Teachers Working With Families: Natural Enemies Or Necessary Allies?, Kirsten Cole

Dissertations, Theses, and Capstone Projects

The complex and crucial connection between families and schools is embodied in relationship between individual teachers and their students' families. Research findings demonstrate that high levels of family engagement lead to greater success for students. Such findings drive policy mandates that hold individual teachers accountable for cultivating this relationship. However, not enough is known about how such mandates are enacted on the ground. In an era when teachers are required to adhere to the standardization of curriculum and the uniform recommendations of "best practice" pedagogic models, teachers must still draw on their whole, complex, human selves when seeking to foster …

Contact-Induced Changes In Word Order And Intonation In The Spanish Of New York City Bilinguals, Carolina Barrera-Tobón

Dissertations, Theses, and Capstone Projects

This dissertation is a variationist sociolinguistic analysis of the variable word order and prosody of copular constructions (Nicolás es feliz versus Feliz es Nicolás, Es Nicolás feliz, Es feliz Nicolás, ‘Nicolas is happy’) in the Spanish of first- and second-generation Spanish-English bilinguals in New York City (henceforth NYC). The data used for the study come from a spoken corpus of Spanish in NYC based on 140 sociolinguistic interviews (details of the corpus will be presented in Chapter Three). This dissertation addresses the question of whether secondgeneration bilinguals have a less flexible word order in Spanish …
