Reconfigurable Solid-State Dye-Doped Polymer Ring Resonator Lasers, Hengky Chandrahalim, Xudong Fan

Faculty Publications

This paper presents wavelength configurable on-chip solid-state ring lasers fabricated by a single-mask standard lithography. The single- and coupled-ring resonator hosts were fabricated on a fused-silica wafer and filled with 3,3′-Diethyloxacarbocyanine iodide (CY3), Rhodamine 6G (R6G) and 3,3′-Diethylthiadicarbocyanine iodide (CY5)-doped polymer as the reconfigurable gain media. The recorded lasing threshold was ~220 nJ/mm² per pulse for the single-ring resonator laser with R6G, marking the lowest threshold shown by solid-state dye-doped polymer lasers fabricated with a standard lithography process on a chip. A single-mode lasing from a coupled-ring resonator system with the lasing threshold of ~360 nJ/mm² per pulse …

Coupled-Oscillator Associative Memory Array Operation For Pattern Recognition, Dmitri E. Nikonov, Gyorgy Csaba, Wolfgang Porod, Tadashi Shibata, Danny Voils, Dan Hammerstrom, Ian A. Young, George I. Bourianoff

Electrical and Computer Engineering Faculty Publications and Presentations

Operation of the array of coupled oscillators underlying the associative memory function is demonstrated for various interconnection schemes (cross-connect, star phase keying and star frequency keying) and various physical implementation of oscillators (van der Pol, phase-locked loop, spin torque). The speed of synchronization of oscillators and the evolution of the degree of matching is studied as a function of device parameters. The dependence of errors in association on the number of the memorized patterns and the distance between the test and the memorized pattern is determined for Palm, Furber and Hopfield association algorithms.

Defensive Routines In Engineering Managers And Non-Engineering Managers -- A Case Analysis, Tyria Riley, Elizabeth A. Cudney

Engineering Management and Systems Engineering Faculty Research & Creative Works

There is a perception that engineers experience challenges in areas such as communication, conflict resolution, and leadership. Defensive routines are actions implemented as a result of being in an embarrassing or threatening situation. This research uses a case study approach to measure whether defensive routines are more common in engineering managers or non-engineering managers. Twenty-seven managers created case studies based on their unique experiences as managers. These case studies were scored, and the results of this research indicate that engineering managers employ defensive routines more commonly than non-engineering managers.

Network And Device Forensic Analysis Of Android Social-Messaging Applications, Daniel Walnycky, Ibrahim Baggili, Andrew Marrington, Jason Moore, Frank Breitinger

All Works

In this research we forensically acquire and analyze the device-stored data and network traffic of 20 popular instant messaging applications for Android. We were able to reconstruct some or the entire message content from 16 of the 20 applications tested, which reflects poorly on the security and privacy measures employed by these applications but may be construed positively for evidence collection purposes by digital forensic practitioners. This work shows which features of these instant messaging applications leave evidentiary traces allowing for suspect data to be reconstructed or partially reconstructed, and whether network forensics or device forensics permits the reconstruction of …

Applying The Transtheoretical Model Of Change To Ergonomic Intervention, Charmaine A. Beckford

Theses and Dissertations

This applied dissertation identified a more effective method of preventing workplace injuries for the employees in a large, private not-for-profit university, in southern Florida. The study lasted over the course of two months, allowing employees’ ample time for effective participation in a structured study design and interviewing the employee participants.

The study evaluated the effects of the transtheoretical model of change (TTM) on ergonomic intervention. The model established the relationship of individual decision making self-efficacy and characterized (a) the relationship between tailoring interventions to match a person’s readiness (stage of change) and ergonomic intervention; (b) the TTM in symptoms occurrence; …

Coercing Pregnancy, A. Rachel Camp

Georgetown Law Faculty Publications and Other Works

Intimate partners coerce thousands of women in the United States into pregnancy each year through manipulation, threats of violence, or acts that deliberately interfere with the use of, or access to, contraception or abortion. Although many of these pregnancies occur within the context of otherwise abusive relationships, for others, pregnancy serves as a trigger for intimate partner violence. Beyond violence preceding or resulting from pregnancy, women who experience coerced pregnancies often suffer other physical, financial and emotional harms. Despite its correlation to domestic violence, reproductive coercion fits imperfectly, if at all, within our existing laws designed to combat domestic violence …

The Making Of A Libertarian, Contrarian, Nonobservant, But Self-Identified Jew, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

Many academics are unaware that I am Jewish, no doubt due, in part, to my last name as well as to my politics, Yet growing up as a Jew in Polish-Catholic Calumet City, Illinois and as a kid from Calumet City attending Temple in Hammond, Indiana made me quite conscious of the tyranny of the majority. This environment, together with the influence of my father, had a deep affect on my views of liberty, justice, individual rights, and the U.S. Constitution. In this brief essay, prepared for a symposium on “Judaism and Constitutional Law: People of the Book,” held at …

3 Critical Challenges For Global Health Security, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

International institutions are poised to make one of the most momentous decisions about the future of global health security since the formation of the World Health Organization (WHO) in 1948.

By the end of this year, 5 global commissions will have published major critiques of global health preparedness, all spurred by the Ebola epidemic, which exposed deep flaws in the international system.

Is Using The Public Trust Doctrine To Protect Public Parkland From Visual Pollution Justifiable Doctrinal Creep?, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

This Article asks whether the public trust doctrine should be applied to stop the construction of a multistory commercial building that will tower over the tree line of Palisades Interstate Park. The building, which received a variance from a local New Jersey zoning commission, will ruin views of the Park, particularly from scenic overlooks across the Hudson River in New York, like the Metropolitan Museum’s Cloisters and the George Washington Bridge. To make this argument, the author draws on the work of renowned public trust scholars, Professors Joseph Sax and Carol Rose, among others. Based on the doctrine’s adaptability to …

The Social Value Of Academic Freedom Defended, J. Peter Byrne

Georgetown Law Faculty Publications and Other Works

This essay argues for the social value of academic freedom in law schools and in the university generally. It takes explicit issue with the arguments of Stanley Fish in Versions of Academic Freedom: From Professionalism to Revolution. The essay maintains that academic freedom is essential to a liberal society and deserving of constitutional protection because scholarship and teaching governed by disciplinary norms represents modernity's best secular effort at separating truth from falsehood.

What's The Harm Of Trademark Infringement?, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

For decades, the concept of actionable trademark infringement has been expanding. Source confusion, reverse confusion, approval/affiliation confusion, initial interest confusion, post-sale confusion, endorsement confusion, and so on, all have won cases for plaintiffs. Whether or not the confusion cost the plaintiff any sales, or was in any way material to consumers, our concept of trademark infringement now encompasses it. These expansions occurred for reasons that seemed sufficient to courts at the time, when advocates offered theories about how all these kinds of confusion could cause harm to the trademark owner. Primarily, courts feared that non-competing uses would preclude trademark owners …

Bank Resolution In The European Banking Union: A Transatlantic Perspective On What It Would Take, Jeffrey N. Gordon, Wolf-Georg Ringe

Faculty Scholarship

The project of creating a Banking Union is designed to overcome the fatal link between sovereigns and their banks in the Eurozone. As part of this project, political agreement for a common supervision framework and a common resolution scheme has been reached with difficulty. However, the resolution framework is weak, underfunded and exhibits some serious flaws. Further, Member States' disagreements appear to rule out a federalized deposit insurance scheme, commonly regarded as the necessary third pillar of a successful Banking Union. This paper argues for an organizational and capital structure substitute for these two shortcomings that can minimize the systemic …

Hobby Lobby: Its Flawed Interpretive Techniques And Standards Of Application, Kent Greenawalt

Faculty Scholarship

At the end of June 2014, the Supreme Court decided one of the most publicized controversies of decades. In a decision covering two cases, widely referred to as Hobby Lobby, the Court held that closely held for-profit corporations, based on their owners' religious convictions, have a right under the Religious Freedom Restoration Act (RFRA) to decline to provide employees with insurance that covers contraceptive devices that may prevent a fertilized egg "from developing any further by inhibiting its attachment to the uterus."

The result has been widely approved by those who favor an extensive scope for religious liberty and …

Sensing Performance Study Of Sic, A Wide Bandgap Semiconductor Material Platform For Surface Plasmon Resonance Sensor, Wei Du, Feng Zhao

Electrical and Computer Engineering Faculty Research & Creative Works

The sensing properties of a surface plasmon resonance (SPR) based waveguide sensor on a wide bandgap semiconductor, silicon carbide (SiC), were studied. Compared to other waveguide sensors, the large bandgap energy of SiC material allows the sensor to operate in the visible and near infrared wavelength range, while the SPR effect by a thin gold film is expected to improve the sensitivity. The confinement factor of the sensor at various wavelengths of the incident light and refractive index of the analyte were investigated using an effective index method. Since the change of analyte type and concentration is reflected by the …

Response To David S. Lindsay Regarding “Self-Archiving Of Publications From The Journal Of Parasitology”, Sue Ann Gardner

University of Nebraska-Lincoln Libraries: Faculty Publications

Response to ASP President, David S. Lindsay, regarding his editorial in volume 36, numbers 3-4, of the ASP Newsletter, titled “Self-archiving of publications from the Journal of Parasitology.” Concludes that the Society's contract with Allen Press will expire at some point and, in the interim, there is an opportunity renegotiate with them thoughtfully, or to look for a better outlet for the time-honored Journal of Parasitology. There are many publishing ventures arising from universities themselves, in libraries and academic departments, on viable and stable electronic platforms, that require very little overhead to administer. If even a fraction …

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

Uncivil Obedience, Jessica Bulman-Pozen, David E. Pozen

Faculty Scholarship

Scholars and activists have long been interested in conscientious law-breaking as a means of dissent. The civil disobedient violates the law in a bid to highlight its illegitimacy and motivate reform. A less heralded form of social action, however, involves nearly the opposite approach. As a wide range of examples attest, dissenters may also seek to disrupt legal regimes through hyperbolic, literalistic, or otherwise unanticipated adherence to their formal rules.

This Article asks how to make sense of these more paradoxical protests, involving not explicit law-breaking but rather extreme law following. We seek to identify, elucidate, and call attention to …

From Contract To Status: Collaboration And The Evolution Of Novel Family Relationships, Elizabeth S. Scott, Robert E. Scott

Faculty Scholarship

The past decade has witnessed dramatic changes in public atti- tudes about and legal status for same-sex couples who wish to marry. These changes demonstrate that the legal conception of the family is no longer limited to traditional marriage. They also raise the possibility that other relationships – cohabiting couples and their children, voluntary kin groups, multigenerational groups, and polygamists – might gain legal recognition as families. This Article probes the challenges faced by aspiring families and the means by which they could attain their goal. It builds on the premise that the state remains committed to social-welfare criteria for …

The Evolution Of Nutritional Co-Endosymbionts In Cicadas, James Theodore Van Leuven

Graduate Student Theses, Dissertations, & Professional Papers

Symbiosis occurs between organisms in all domains of life. The evolution of obligate symbionts from free-living bacteria typically results in the loss of genes involved in metabolic independence and an overall reduction in genome size. Outside the organelles, the most extreme examples of genome reduction come from the intracellular symbionts of sap-feeding insects. The genomes of these bacteria encode very few genes other than those involved in translation, replication, and amino acid synthesis. Candidatus Hodgkinia cicadicola (Hodgkinia) and Candidatus Sulcia muelleri (Sulcia) live in specialized insect cells (bacteriocytes) of the cicada Diceroprocta semicincta, and have undergone severe gene loss. Hodgkinia …

Vulnerable Populations' Perspectives On Climate Engineering, Wylie Allen Carr

Graduate Student Theses, Dissertations, & Professional Papers

Over the past decade, climate engineering—or the intentional, large-scale manipulation of the global environment to reduce or reverse anthropogenic climate change—has garnered increasing attention from scientists and policymakers. However, impacts from climate engineering will be unevenly distributed. Vulnerable populations already being disproportionately impacted by climate change might benefit or be made worse off. As such, legislators, members of the public, and academics alike have asserted that vulnerable populations deserve to have a say in the research and development of climate engineering technologies and the policies that will govern them. These calls have gone largely unfulfilled. The research presented in this …

Investigating The Influence Of Airborne Particulate Matter Source And Size On Health Outcomes, Matthew Darryl Ferguson

Graduate Student Theses, Dissertations, & Professional Papers

Air pollution is an environmental health concern throughout the world, and is responsible for an estimated 1 out of 8 deaths. As a common component of air pollution, particulate matter (PM) is one of six criteria air pollutants regulated by the Environmental Protection Agency (EPA), with existing ambient standards for both PM2.5 and PM10. Currently there are no health-based regulations for the size fraction between 2.5 and 10 μm, commonly known as the coarse fraction (PMc). Previous studies show that PMc can induce health effects such as increased inflammation, and may be more detrimental to susceptible populations when directly compared …

Admin, Elizabeth F. Emens

Faculty Scholarship

This Article concerns a relatively unseen form of labor that affects us all, but that disproportionately burdens women: admin. Admin is the office type work – both managerial and secretarial – that it takes to run a life or a household. Examples include completing paperwork, making grocery lists, coordinating schedules, mailing packages, and handling medical and benefits matters. Both equity and efficiency are at stake here. Admin raises distributional concerns about those people – often women – who do more than their share of this work on behalf of others. Even when different-sex partners who both work outside the home …

The Last Wolves Of Isle Royale, Kasey Rahn

Graduate Student Theses, Dissertations, & Professional Papers

Isle Royale National Park, located in Michigan, is home to a wolf population that is in decline due to complications from inbreeding. Scientists and managers struggle to decide whether to intervene. Some scientists promote bringing new wolves to the island to restore the population because they say the decline is human-caused. Others promote “watchful waiting.” To date, the National Park Service has not interceded and is currently undergoing a management planning process. The issue raises questions about what it means to manage wildlife in an era of change. Should humans intervene to protect wildlife in the face of climate change …

Do Democratic Governments Improve Environmental Quality?, Yoonsoo Nam

Graduate Student Theses, Dissertations, & Professional Papers

My research question is whether democratic countries improve the environment. This research question is important because many nowadays people are more than ever concerned about environmental quality, and researchers have produced mixed results of democratic governments’ effects on the environment. As an attempt to contribute to this area of research, I implement three different types of heterogeneity in the relationships between democratic countries and environmental quality. These three different types of heterogeneity include different environmental outcomes, separate components of democracy, and countries with different income levels. By using these three different types of heterogeneity, I may better understand the mechanisms …
