Joint Lm Test For Homoskedasticity In A One-Way Error Component Model, Badi H. Baltagi, Georges Bresson, Alain Pirotte

Center for Policy Research

This paper considers a general heteroskedastic error component model using panel data, and derives a joint LM test for homoskedasticity against the alternative of heteroskedasticity in both error components. It contrasts this joint LM test with marginal LM tests that ignore the heteroskedasticity in one of the error components. Monte Carlo results show that misleading inference can occur when using marginal rather than joint tests when heteroskedasticity is present in both components.

Ranking Inequality: Applications Of Multivariate Subset Selection, William C. Horrace, Joseph T. Marchand, Timothy M. Smeeding

Center for Policy Research

Inequality measures are often presented in the form of a rank ordering to highlight their relative magnitudes. However, a rank ordering may produce misleading inference, because the inequality measures themselves are statistical estimators with different standard errors, and because a rank ordering necessarily implies multiple comparisons across all measures. Within this setting, if differences between several inequality measures are *simultaneously* and statistically insignificant, the interpretation of the ranking is changed. This study uses a multivariate subset selection procedure to make simultaneous distinctions across inequality measures at a pre-specified confidence level. Three applications of this procedure are explored using country-level data …

Concepts Learning Using Technology For Rapid Feedback And Student Engagement, John Chen, Jennifer A. Kadlowec, Dexter C. Whittinghill

Mechanical Engineering

In this project our goal is to improve student learning in the foundation mechanics course Statics. In this case improved learning is defined as knowledge retention (durability) and knowledge application in a different environment (transferability). We aim to do this by providing rapid feedback to students of their understanding of key concepts and skills being presented. The feedback system acts as the focal point and catalyst to encourage students to assist each other in correcting misconceptions or deepening each other’s understanding of the topic or skill at hand. Furthermore, the system allows the professor to assess the students’ level of …

Constitutionalization, Girardeau A. Spann

Georgetown Law Faculty Publications and Other Works

Students of constitutional law tend to suspect pretty early on that the Constitution simply means whatever the Supreme Court says that it means. Rather than fight that intuition, I think it is best to treat the student insight as one of the basic starting assumptions when teaching a course in Constitutional Law. The goal then becomes to help students figure out how best to maneuver and feel comfortable in a legal universe where the Constitution has only contingent meaning.

What the Supreme Court does when it clothes its political policy preferences in the garb of constitutional law can be described …

Telling Stories And Keeping Secrets, Abbe Smith

Georgetown Law Faculty Publications and Other Works

Nothing is better than a good story. You don't need to be a trial lawyer to know this, but you wouldn't be a very good trial lawyer if you didn't. There is a reason trial lawyers are favored dinner party guests: if the food is a flop, the energy level low, and the people in attendance do not have much in common, there will at least be a good story for entertainment. Good trial lawyers have the gift of gab and a bounty of endless material.

Criminal trial lawyers have it even better. They don't just recount tales involving conflict …

Direct Vs. Indirect Obligations Of Corporations Under International Law, Carlos Manuel Vázquez

Georgetown Law Faculty Publications and Other Works

International law today addresses the conduct of private corporations in a variety of areas. With very few exceptions, however, international law regulates corporate conduct indirectly--that is, by requiring states to enact and enforce regulations applicable to corporations and other non-state actors. Only a small number of international legal norms--primarily those relating to war crimes, crimes against humanity, and forced labor--apply directly to non-state actors. Scholars have argued forcefully that international law should move in the direction of directly imposing obligations on corporations. These arguments overlook important aspects of the problem. If international legal norms were extended to corporations and backed …

Gay Is Good: The Moral Case For Marriage Equality And More, Chai R. Feldblum

Georgetown Law Faculty Publications and Other Works

The struggle for marriage equality in this country is ripe for an intervention. If the effort continues along in the manner in which it has been headed, gay couples may or may not succeed in gaining access to civil marriage. But even if gay couples succeed in "getting marriage," the gay rights movement may have missed a critical opportunity-a chance to make a positive moral case for gay sex and gay couples. In other words, it will have missed the opportunity to argue that "gay is good."

Moreover, to the extent that the struggle for marriage equality focuses solely on …

The Place Of The User In Copyright Law, Julie E. Cohen

Georgetown Law Faculty Publications and Other Works

Copyright doctrine . . . is characterized by the absence of the user. As copyright moves into the digital age, this absence has begun to matter profoundly. As I will show, the absence of the user has consequences that reach far beyond debates about the legality of private copying, or about the proper scope of user-oriented exemptions such as the fair use and first sale doctrines. The user's absence produces a domino effect that ripples through the structure of copyright law, shaping both its unquestioned rules and its thorniest dilemmas. The resulting imbalance - empty space where one cornerstone of …

Squaring The Circle? Reconciling Sovereignty And Global Governance Through Global Government Networks (Review Of Anne-Marie Slaughter, A New World Order), Kenneth Anderson

Book Reviews

This book review summarizes and critiques A New World Order, offering both an internal critique of the argument's consistency as well as an outside critique of the argument from the standpoint of the value of democratic sovereignty. The review locates Slaughter's argument within the debate over international relations realism and idealism, and further locates it within a continuum of seven idealized positions in the debate between global governance and sovereignty, with pure sovereignty at one extreme and world government at the other, with the most relevant positions of democratic sovereignty and liberal internationalism located in the middle. The article concludes …

Neoclassicism, Artificial Intelligence, And The Marginalization Of Ethics, John B. Davis

Economics Faculty Research and Publications

Purpose – The paper examines the dependence of the positivist and welfarist preference satisfaction paradigm of neoclassical economics upon an implicit functionalist philosophy of mind. Functionalism is the doctrine that mental states are strictly materialistic and understandable in cause-effect terms. An important aspect of functionalism is the multiple realizability thesis, namely, that mental states can be realized in any type of hardware, whether human brain or computer.

Design/methodology/approach – The approach used involves investigating the fact-value distinction after Robbins in terms of the positivist meta-ethical view known as emotivism, and then explaining emotivism as inherently functionalist. Functionalist thinking itself is …

Drum Source Separation Using Percussive Feature Detection And Spectral Modulation, Dan Barry, Derry Fitzgerald, Eugene Coyle, Robert Lawlor

Conference papers

This papers presents a method for the separation and resynthesis of drum sources from single channel polyphonic mixtures. The frequency domain technique involves identifying the presence of a drum using a novel percussive feature detection function, after which the short-time magniture spectrum is estimated and scaled according to an estimated time-amplitude function derived from the percussive measure. In addition to producing high quality separation results, the method described is also a useful pre-process for drum transcription techniques such as Prior Subspace Analysis in the presence of pitched instruments.

Comparison Of Signal Reconstruction Methods For The Azimuth Discrimination And Resynthesis Algorithm, Dan Barry, Robert Lawlor, Eugene Coyle

Conference papers

The Azimuth Discrimination and Resynthesis algorithm (ADRess) has been shown to produce high quality sound source separation results for intensity panned stereo recordings. There are however, artifacts such as phasiness which become apparent in the separated signals under certain conditions. This is largely due to the fact that only the magnitude spectra for the separated sources are estimated. Each source is then resynthesised using the phase information obtained from the original mixture. This paper describes the nature and origin of the associated artifacts and proposes alternative techniques for resynthesising the separated signals. A comparison of each technque is then presented.

Audio Time-Scale Modification Using A Hybrid Time-Frequency Domain Approach, David Dorran, Eugene Coyle, Robert Lawlor

Conference papers

Frequency-domain approaches to audio time-scale modification introduce a reverberant artefact into the time-scaled output due to a loss in phase coherence between subband components. Whilst techniques have been developed which reduce the presence of this artifact, it remains a source of difficulty. A method of time-scaling is presented that reduces the presence of the reverberation by taking advantage of some flexibility that exists in the choice of phase required so as to maintain horizontal phase coherence along frequency-domain subband components. The approach makes use of appealing aspects of existing time-domain and frequency-domain time-scaling techniques.

Multi Pitch Estimation By Using Iir Comb Filters, Mikel Gainza, Robert Lawlor, Eugene Coyle

Conference papers

A technique for detecting the pitches of a polyphonic signal is presented. The system utilises modified IIR comb filters, which are generated to ensure that a null (stop band notches) exists at multiples of note frequencies and that a very flat pass band is present in the remain of the spectrum. Thus, the signal spectrum is not distorted after applying the filters to the audio signal, which is the case when using FIR comb filters. the presented approach improves upon an existing multi pitch detection model based on a FIR comb filter framework.

Multi-Channel Audio Time-Scale Modification, David Dorran, Robert Lawlor, Eugene Coyle

Conference papers

Phase vecoder based approaches to audio time-scale modification introduce a reverberant artefact into the time scaled output. Recent techniques have been developed to reduce the presence of this artefact; however, these techniques have the effect of introducing additional issues relating to their application to multi-channel recordings. This paper addresses these issues by collectively analysing all channels prior to time-scaling each individual channel.

The Influence Of Parenting Styles On The Development Of Moral Judgment In College Level Adolescents, Scott M. Hawkins

Doctoral Dissertations and Projects

This research project addresses the relationship between parenting styles and the development of moral judgment in college students enrolled in a four year private University in Central Virginia. The purpose of this study is to identify the extent to which parenting styles are one of the "building blocks" for the development of moral judgment in adolescents. The instruments used are the Parental Authority Questionnaire (Buri, 1988) and the Defining Issues Test - II (Rest, 1999). The researcher hypothesized that the levels of moral judgment found in college students who perceive that they were parented by parents utilizing an Authoritative parenting …

Lay Shepherding: Developing A Pastoral Care Ministry For The Small To Mid-Sized Church, Barry G. Lawson

Doctoral Dissertations and Projects

A survey of Wesleyan churches and a review of current literature reveals that most pastors are bearing the burden of pastoral care alone. Only a few churches are effectively equipping and empowering lay persons to help provide this needed and meaningful ministry within the body of Christ. The purpose of this project is to demonstrate biblically and historically that the laity are gifted for ministry and that they are called to the task of shepherding God's flock. Further, this project seeks to present a model for implementing a lay shepherding ministry in the small to mid-sized church.

Advanced Glycation Endproducts Analysis Of Glucosamine With Reducing Sugars, Dna Nucleosides And Serum Proteins, Udayan Dutta

Open Access Dissertations

Advanced glycation endproducts (AGE) are a complex and heterogeneous group of compounds formed by the nonenzymatic reactions of reducing sugars with amino acids and proteins. The reaction is called the Maillard reaction and is central to all protein glycation studies. Accumulation of AGE in human tissue has been associated with the pathology of various diseases like diabetes, Alzheimer's disease, renal failure and ageing and has generated great interest in methods for characterizing the glycated products. Glucosamine GlcN is an unregulated high profile dietary supplement used for the treatment of osteoarthritis with few side effects. There is very little understanding on …

Validation Of A Tool To Measure Drug Knowledge: Evaluating Bioterrorism Preparedness Activities, Gregory A. Low

Open Access Dissertations

Background. Pharmaceutical supplies sufficient to protect millions of people are positioned to respond to a bioterrorist attack in the United States of America, but the educational resources, programs, material, and health professional staffing, to utilize those supplies optimally may be underdeveloped. Professionals and municipalities require objective tools to measure their ability to communicate necessary drug information to adhere to emergency prophylactic regimens. Objective. This research project created a survey tool and laid the foundation to establish the tool's validity to measure patient drug knowledge in bioterrorism preparedness activities that involve the dispensing of prophylactic medications. Methods. Test construction was based …

Minutes, reports, correspondence, financial records, program notes, newspaper clippings, membership records, publications, constitutions and bylaws, historical data, yearbooks, …

Are There Any Checks And Balances On The Government's Power To Check Our Balances? The Fate Of Financial Privacy In The War On Terrorism, Eric J. Gouvin

Faculty Scholarship

In the three years since the terrorist attacks of September 11th, 2001, the laws affecting money laundering and financial privacy in the United States have been changed to give law enforcement agencies easier access to financial information. Although the changes to the law were passed with the claim that they were needed to intercept terrorist financing, the anti-money laundering provisions enacted by the USA PATRIOT Act are being used routinely against non-terrorist criminal suspects as part of regular law enforcement processes. Although the apprehension of ordinary criminals by any means available will sound perfectly ceptable to many, it is at …
