Unified Power Quality Conditioner For Grid Integration Of Wind Generators, Jayanti Navilgone Ganesh

Doctoral

A Unified Power Quality Conditioner (UPQC) is relatively a new member of the custom power device family. It is a comprehensive custom power device, with integrated shunt and series active filters. The cost of the device, which is higher than other custom power/FACTS devices, because of twin inverter structure and control complexity, will have to be justified by exploring new areas of application where the cost of saving power quality events outweighs the initial cost of installation. Distributed generation (such as wind generation) is one field where the UPQC can find its potential application. There has been a considerable increase …

Drop Photometer Design., Kevin Tiernan

Doctoral

The tensiograph drop analyser, operating in the mode of ultraviolet-visual absorption photometer, was re-engineered to improve measurement accuracy. As well as instrumentation re-design, the other objective of the research was to analyse tensiograph signals to explore how their features are defined by drop properties. Using fibre optic technology, the tensiograph emits a light beam into a growing pendant drop whereupon it undergoes a number of internal reflections. A portion of the reflected light energy is coupled to a photodiode producing a proportional current that is electronically processed and transferred to a computer for analysis. The signal produced, known as the …

Development Of Fiber Bend Loss Edge Filter, Pengfei Wang

Doctoral

This PhD thesis addresses several aspects of macrobending loss in single-mode optical fibers. The context for the work is the development of an edge filter for a rapid wavelength measurement system. Based on scalar approximation theory and the beam propagation method, a simulation platform is developed and used to predict the macrobending loss of singlemode fiber with single or multiple coating layers. A single-mode step index fiber macrobending loss edge filter is investigated theoretically in terms of baseline loss, discrimination range and polarization dependent loss (PDL). The theoretical analysis is supported by a range of experimental investigations and results. The …

The Influence Of The Servicescape On Post-Consumption Processes, Daire Hooper

Doctoral

The physical and atmospheric cues in service environments have long been accepted as potent contributors to consumers’ overall evaluations of their service experiences. Theoretical frameworks conceptualising how these environmental cues impact on both emotional and cognitive processes have been put forward, yet the empirical work supporting these theories has become highly disjointed with a great deal of confusion regarding what should be classified as an environmental stimulus. By integrating the extant literature, this dissertation attempts to overcome theoretical ambiguities and proposes a second order factor model of service environments, also known as the servicescape, which is subsequently tested using a …

Factors Affecting The Information Quality Of Personal Web Portfolios, P. Katerattanakul, Keng Siau

Research Collection School Of Computing and Information Systems

Personal Web portfolios have become a popular information source and an effective method for individuals to present themselves to others in cyberspace. Thus, the quality of personal Web portfolios is critical and affects the perception that others have of the individuals. But how do we measure quality of personal Web portfolios? What are the important factors affecting quality of personal Web portfolios? This study presents the development of an instrument measuring factors affecting information quality of personal Web portfolios. The proposed instrument, based on the Information Quality framework, was refined and validated to assess its construct validity, convergent validity, and …

Beating The Spin-Down Limit On Gravitational Wave Emission From The Crab Pulsar, B. Abbott, R. Abbott, R. Adhikari, P. Ajith, B. Allen, G. Allen, R. Amin, S. B. Anderson, W. G. Anderson, M. A. Arain, M. Araya, H. Armandula, P. Armor, Y. Aso, S. Aston, P. Aufmuth, C. Aulbert, S. Babak, S. Ballmer, H. Bantilan, B. C. Barish, C. Barker, D. Barker, B. Barr, P. Barriga, M. A. Barton, M. Bastarrika, K. Bayer, J. Betzwieser, P. T. Beyersdorf, I. A. Bilenko, Tiffany Z. Summerscales

Faculty Publications

We present direct upper limits on gravitational wave emission from the Crab pulsar using data from the first 9 months of the fifth science run of the Laser Interferometer Gravitational-wave Observatory (LIGO). These limits are based on two searches. In the first we assume that the gravitational wave emission follows the observed radio timing, giving an upper limit on gravitational wave emission that beats indirect limits inferred from the spin-down and braking index of the pulsar and the energetics of the nebula. In the second we allow for a small mismatch between the gravitational and radio signal frequencies and interpret …

First Joint Search For Gravitational-Wave Bursts In Ligo And Geo 600 Data, B. Abbott, R. Abbott, R. Adhikari, P. Ajith, B. Allen, G. Allen, R. Amin, S. B. Anderson, W. G. Anderson, M. A. Arain, M. Araya, H. Armandula, P. Armor, Y. Aso, S. Aston, P. Aufmuth, C. Aulbert, S. Babak, S. Ballmer, H. Bantilan, B. C. Barish, C. Barker, D. Barker, B. Barr, P. Barriga, M. A. Barton, I. Bartos, M. Bastarrika, K. Bayer, J. Betzwieser, P. T. Beyersdorf, Tiffany Z. Summerscales

Faculty Publications

We present the results of the first joint search for gravitational-wave bursts by the LIGO and GEO 600 detectors. We search for bursts with characteristic central frequencies in the band 768-2048 Hz in the data acquired between 22 February and 23 March, 2005 (fourth LSC Science Run-S4). We discuss the inclusion of the GEO 600 data in the Waveburst-CorrPower pipeline that first searches for coincident excess power events without taking into account differences in the antenna responses or strain sensitivities of the various detectors. We compare the performance of this pipeline to that of the coherent Waveburst pipeline based on …

Schoolyard Improvements And Standardized Test Scores: An Ecological Analysis, Russ Lopez, Richard Campbell, James Jennings

Gastón Institute Publications

Boston MA’s schoolyards had seriously deteriorated since the middle of the 20th century resulting in dangerous and unusable outdoor spaces. Beginning in the mid 1990s, a program to renovate these schoolyards has resulted in approximately half of the schools now having outdoor recreational, learning and garden spaces. This study compared the 4th grade test score results in renovated vs. unrenovated schools. Controlling for school demographics, schools that had a renovated schoolyard had more of their students passed the state mandated math test (1.06, 95% confidence interval = .00012, .12). Effects on the state mandated English language arts test were not …

Punishing Family Status, Jennifer M. Collins, Ethan J. Leib

Faculty Journal Articles and Book Chapters

This Article focuses upon two basic but under-explored questions: when does, and when should, the state use the criminal justice apparatus to burden individuals on account of their familial status? We address the first question in Part I by revealing a variety of laws permeating the criminal justice system that together form a string of family ties burdens, laws that impose punishment upon individuals on account of their familial status. The seven burdens we train our attention upon are omissions liability for failure to rescue, parental responsibility laws, incest, bigamy, adultery, nonpayment of child support, and nonpayment of parental support. …

Voluntarism, Vulnerability, And Criminal Law: A Response To Professors Hills And O'Hear, Ethan J. Leib, Dan Markel, Jennifer M. Collins

Faculty Journal Articles and Book Chapters

This Response addresses the criticisms of our project by Professors Rick Hills and Michael O'Hear. Before we address those challenges, we first want to reiterate our gratitude to the B.U. Law Review for hosting an exchange based on our article, Punishing Family Status (forthcoming BU LR, December 2008), and to Professors Hills and O'Hear for their careful and subtle analysis of that article.

Additionally, it's worth recapitulating what our bottom-line conclusions are so we can better see if there are any practical disagreements with our critics. Summarizing quickly: we support decriminalization in the cases of parental responsibility laws (based on …

Amp-Activated Protein Kinase Is Involved In Hormone-Induced Mouse Oocyte Meiotic Maturation In Vitro, Jing Chen, Stephen M. Downs

Biological Sciences Faculty Research and Publications

We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro. The present study was carried out to determine whether AMPK activation is involved in hormone-induced maturation. Follicle-stimulating hormone (FSH) and the EGF-like peptide, amphiregulin (AR), are potent inducers of maturation in cumulus cell-enclosed oocytes (CEO). Within 3 h of FSH treatment, phospho-acetyl CoA carboxylase (ACC) levels were increased in germinal vesicle (GV)-stage oocytes when compared to non-stimulated controls and remained elevated throughout 9 h of culture, indicating AMPK activation. A similar response to AR was observed …

The African-American Child Welfare Act: A Legal Redress For African-American Disproportionality In Child Protection Cases, Jessica Dixon Weaver

Faculty Journal Articles and Book Chapters

This article proposes a radical change in the way African-American children and families are handled within the legal system when abuse and neglect are at issue. African-American disproportionality in child protection cases is significant for the United States because documentation shows that African-American children are overrepresented in the child welfare system in forty-eight states, although research shows that there is no difference in the occurrence of child abuse and neglect among the races. The first part of the article presents an overview of disproportionality by presenting the national statistics and research, revealing where racial bias and disparate treatment occurs within …

One Share, One Vote And The False Promise Of Shareholder Homogeneity, Grant M. Hayden, Matthew T. Bodie

Faculty Journal Articles and Book Chapters

Shareholder democracy has blossomed. The once moribund shareholder franchise is now critical in takeover contests, merger decisions, and board oversight. However, the mechanisms of this vote remain largely undertheorized. In this Article, we use voting rights and social choice theory to develop a new approach to the corporate franchise. Political democracies typically tie the right to vote to the level of a person's interest in the outcome of the election. Corporate democracies, on the other hand, tend to define the requisite institutional interest quite narrowly, and thus restrict the right to vote to shareholders alone. This restriction has found its …

The Failure Of Title Vii As A Rights-Claiming System, Deborah L. Brake, Joanna L. Grossman

Faculty Journal Articles and Book Chapters

This Article takes a comprehensive look at the failure of Title VII as a system for claiming nondiscrimination rights. The Supreme Court's recent decision in Ledbetter v. Goodyear Tire & Rubber Company, 127 S. Ct. 2162 (2007), requiring an employee to assert a Title VII pay discrimination claim within 180 days of when the discriminatory pay decision was first made, marks the tip of the iceberg in this flawed system. In the past decade, Title VII doctrines at both ends of the rights-claiming process have become increasing hostile to employees. At the front end, Title VII imposes strict requirements on …

Examining The Pipeline: A Contemporary Assessment Of Private Investments In Public Equity ('Pipes'), Marc I. Steinberg, Emmanuel Obi

Faculty Journal Articles and Book Chapters

This article analyzes the practical and theoretical underpinnings as well as recent regulatory developments impacting PIPEs. Specifically, the authors examine the traditional capital financing alternatives, primarily the registered offering and private placement option, the PIPE as a relatively new and emerging alternative to traditional avenues of capital formation, and the recent regulatory changes that are bound to have a tremendous impact on the long-term viability of the PIPE as a means for effectively raising capital. The authors conclude that, on balance, the PIPE, as a distinct capital financing mechanism, may be advantageous to both PIPE investors and affected issuers, particularly …

Disney Goes Goofy: Agency, Delegation & Corporate Governance, Marc I. Steinberg, Matthew D. Bivona

Faculty Journal Articles and Book Chapters

In the wake of the corporate debacles that have occurred in the last decade, there has been an increasing legislative and judicial focus on the reform of corporate governance standards. Such reforms, including the Sarbanes-Oxley Act, sing the praises of independent directors in effectuating meaningful corporate governance. The Delaware courts as well have emphasized the importance of independent directors in the corporate governance framework.

The Delaware Supreme Court’s decision in Disney seems to be a reaffirmance of the business judgment rule as applied to corporate directors; however, the court’s highly-publicized decision ignores a crucial component of the case: the Delaware …

Vladimir Putin And The Rule Of Law In Russia, Jeffrey D. Kahn

Faculty Journal Articles and Book Chapters

During his two terms as President of Russia, did Vladimir Putin further the net development of a legal culture in Russia? This article is based on public lectures given in late 2007 and early 2008 at Oxford University, the Norwegian Institute of International Affairs (NUPI), and the Kennan Institute at the Woodrow Wilson International Center for Scholars.

This article examines three "windows" into the development of Russia's legal culture under Vladimir Putin: (1) the Second Chechen War; (2) Russian membership in the Council of Europe; and, (3) renewed efforts under Putin at codification of law, as evidenced by the creation …

Russia's Criminal Procedure Code Five Years Out, William Burnham, Jeffrey D. Kahn

Faculty Journal Articles and Book Chapters

After a long delay in drafting, a new Criminal Procedure Code for Russia was passed in 2001 and went into effect in 2002. The new Code contains some striking innovations, most notably changes at the trial stage, which implement the constitutional requirements of adversarial principles. However, it also retains several throwbacks to the past, particularly its preservation of the formal pretrial investigation, during which evidence is parsed and collected in a dossier, which then dominates the trial of the case. The result is that old and new constantly contend with each other. Implementation of the new adversarial procedures is also …

Clarifying The Boundary Between The Parol Evidence Rule And The Rules Governing Subsequent Oral Modifications, Gregory S. Crespi

Faculty Journal Articles and Book Chapters

In this article, the author analyzes the rules that govern the legal effectiveness of oral agreements that purport to modify written contracts. The article includes a discussion of four situations that raise difficult questions of whether oral agreements should be regarded as pre-written contract agreements (rather than as subsequent oral modifications) for purposes of the parol evidence rule. The author concludes that no doctrinal changes are called for in the contract formation timing rules currently applicable to these situations unless such changes are accompanied by broader judicial enforcement of no-oral-modification clauses.

Codification Of Late Roman Inheritance Law: Fideicommissa And The Theodosian Code, Joshua C. Tate

Faculty Journal Articles and Book Chapters

It has long been known that most of the private law content of the Theodosian Code has not been preserved independently of the Lex Romana Visigothorum, or Breviary of Alaric. Certain constitutions, not contained in the Breviary but dating to the period covered by the Theodosian Code, have survived in the Code of Justinian. There has been debate, however, as to whether all of these constitutions were contained in the Theodosian Code.

This Article discusses this problem with respect to a particular topic: fideicommissa. The Article considers whether a particular constitution, CJ 6.37.21, might have been included in the Theodosian …

Inheritance Rights Of Nonmarital Children In Late Roman Law, Joshua C. Tate

Faculty Journal Articles and Book Chapters

Late Roman legislation regarding the inheritance rights of nonmarital children is a tangled web of seemingly conflicting constitutions. Focusing on the period 371-428 AD, this Article argues that, when two particular Western laws from that era are considered alongside others issued at the same time, it is possible to discern some wider legislative trends that may help to contextualize the different attitudes shown toward nonmarital children. C.Th. 4.6.4 (371), a Western law beneficial to nonmarital children, can arguably be linked with another Western law issued shortly afterward granting a privilege to the daughters of actresses, another disfavored class in the …

Christianity And The Legal Status Of Abandoned Children In The Later Roman Empire, Joshua C. Tate

Faculty Journal Articles and Book Chapters

Late Roman imperial legislation relating to abandoned or exposed children has been the subject of much debate. Some have argued that the constitutions of Constantine relating to abandoned children marked a new Christian influence, and that the years between Constantine and Justinian merely refined and explained Constantine's legislation. This paper argues that the legislation of Constantine was not distinctly Christian in content, but that some Christian influence can be seen in the rhetoric of imperial constitutions beginning in the fifth century, and that Christian ideas seem to have affected both the substance and the rhetoric of Justinian's legislation. The paper …

A Traditionalist Case For Gay Marriage, Dale Carpenter

Faculty Journal Articles and Book Chapters

This article presents an argument for same-sex marriage within traditionalism or Burkeanism school of conservatism. The author begins by describing briefly Burkean conservatism. Second, he sketches, based on that description, a case against the recognition of gay marriages. Third, the author outlines an affirmative argument for same-sex marriage. Fourth, he reconsiders, in the light of those arguments, the Burkean case against same-sex marriage. Finally, he discusses what a Burkean conservative ought to say about the pace and the process for achieving same-sex marriage.

Straight Acting, Dale Carpenter

Faculty Journal Articles and Book Chapters

This article explores the meaning of “straight acting,” a term one often hears among gay people. How, why, and by whom is it used? What purposes does it serve and what purposes does the reaction to it serve? How does its use by gays compare to the use of the term “acting white” by blacks? And, since this is a law journal, there's the necessary question: what is law's role in straight acting?

The Enigma Of Standing Doctrine In Texas Courts, William V. Dorsaneo Iii

Faculty Journal Articles and Book Chapters

This Article examines federal and Texas standing doctrine and makes recommendations for the principled application of the traditional non-jurisdictional approach of the procedural defense of standing under Texas law for common law claims and statutory rights of action and for the concomitant restriction of the jurisdictional aspects of standing to litigation brought by private persons and governmental units to enforce public rights or compel the performance of public duties. This Article also explains how the concepts of standing and capacity can be reconciled and harmonized.

Rethinking Recycling, Jeffrey M. Gaba

Faculty Journal Articles and Book Chapters

Subtitle C of the Resource Conservation and Recovery Act (RCRA) establishes the so-called “cradle to grave” regulatory program over hazardous “solid wastes.” Although not obviously wastes, the United States Environmental Protection Agency (EPA) has consistently asserted jurisdiction to regulate some class of recyclable materials under Subtitle C. It has done this through a regulatory definition of “solid waste” that establishes a complex and confusing scheme that includes, excludes, and exempts recyclable materials from regulatory requirements in an almost incomprehensible fashion. In 2008, EPA added to this complexity by promulgating a new set of conditional exclusions that exempts certain reclaimed materials …

Taxation Of Supernormal Returns, David Elkins, Christopher H. Hanna

Faculty Journal Articles and Book Chapters

In the last ten to fifteen years, a number of articles have been written on the differences between a normative income tax system and a normative consumption tax system, with much of the discussion focusing on the taxation of the risk-free rate of return and the risk premium from an investment. As is generally accepted, under certain assumptions an accrual income tax system taxes the risk-free rate of return on capital but does not tax the risk premium, while a cash-flow consumption tax system (or a wage tax system) taxes neither the risk-free rate of return nor the risk premium. …

Effect Of Ethanol On Microbial Community Structure And Function During Natural Attenuation Of Benzene, Toluene, And O-Xylene In A Sulfate-Reducing Aquifer, Kevin Feris, Doug Mackay, Nick De Sieyes, Irina Chakraborty, Murray Einarson, Krassimira R. Hristova, Kate M. Scow

Biological Sciences Faculty Research and Publications

Ethanol (EtOH) is a commonly used fuel oxygenate in reformulated gasoline and is an alternative fuel and fuel supplement. Effects of EtOH release on aquifer microbial ecology and geochemistry have not been well characterized in situ. We performed a controlled field release of petroleum constituents (benzene (B), toluene (T), o-xylene (o-X) at ∼1–3 mg/L each) with and without EtOH (∼500 mg/L). Mixed linear modeling (MLM) assessed effects on the microbial ecology of a naturally sulfidic aquifer and how the microbial community affected B, T, and o-X plume lengths and aquifer geochemistry. Changes in microbial community structure …
