Shakespeare And The Cultural Olympiad: Contesting Gender And The British Nation In The Bbc’S Hollow Crown, L Monique Pittman Jan 2016

Shakespeare And The Cultural Olympiad: Contesting Gender And The British Nation In The Bbc’S Hollow Crown, L Monique Pittman

Faculty Publications

As part of the 2012 Cultural Olympiad celebrating both the Queen's Diamond Jubilee and the London Olympics, the BBC launched a season of programs, entitled Shakespeare Unlocked, most notably presenting the plays of the second tetralogy in four feature-length adaptations released under the unifying title The Hollow Crown. These plays so obviously engaged with the question of English nationalism suited a year in which the United Kingdom wrestled with British identity in a post-colonial and post-Great Recession world. Through its adaptative and filmic vocabularies, however, The Hollow Crown advances a British nationalism unresponsive to the casualties — often women and …


One Person, One Weighted Vote, Ashira Pelman Ostrow Jan 2016

One Person, One Weighted Vote, Ashira Pelman Ostrow

Hofstra Law Faculty Scholarship

This Article argues that weighted voting should be used to comply with the constitutional one-person, one-vote requirement while preserving representation for political units on the legislative body. First, this Article demonstrates that weighted voting satisfies the quantitative one-person, one-vote requirement by equalizing the mathematic weight of each vote. Second, this Article demonstrates that weighted voting has the potential to remedy several negative consequences of equal-population districts. Specifically, this Article argues that by preserving local political boundaries, weighted voting eliminates the decennial redistricting process that gives rise to claims of partisan gerrymandering, enables local governments to function both as administrative arms …


Branded, Irina D. Manta Jan 2016

Branded, Irina D. Manta

Hofstra Law Faculty Scholarship

Marks are traditionally said to serve three functions that are separate from the goals of other forms of IP: source identification, advertising, and guarantee of quality. The story, however, that patents and copyrights incentivize creation and that trademarks do not fulfill that purpose does not withstand scrutiny. This Article argues that brands have evolved in such a way that they serve important incentivizing purposes of their own, and that trademark law influences their ability to do so. This Article identifies three generally neglected functions of trademarks. The first pertains to the creation of original, unique marks and brands in and …


The Need For Annotated Corpora From Legal Documents, And For (Human) Protocols For Creating Them: The Attribution Problem, Vern R. Walker Jan 2016

The Need For Annotated Corpora From Legal Documents, And For (Human) Protocols For Creating Them: The Attribution Problem, Vern R. Walker

Hofstra Law Faculty Scholarship

This paper argues that in order to make progress today in automating argumentation mining from legal documents, we have a critical need for two things. First, we need a sufficient supply of manually annotated corpora, as well as theoretical and experimental evidence that those annotated data are accurate. Second, we need protocols for effectively training people to perform the tasks and sub-tasks required to create those annotations. Such protocols are necessary not only for a team approach to annotation and for quality assurance of the finished annotations, but also for developing and testing software to assist humans in the process …


Beyond Arl Diversity Initiatives: Peer Mentoring, Genevia Chamblee-Smith, Christian I.J. Minter Jan 2016

Beyond Arl Diversity Initiatives: Peer Mentoring, Genevia Chamblee-Smith, Christian I.J. Minter

Posters and Presentations: Leon S. McGoogan Health Sciences Library

Background: The purpose of this research project is to highlight the benefits of peer mentoring as an ongoing resource for career advancement and retention among alumni of the Association of Research Libraries’ Career Enhancement Program (CEP) and Initiative to Recruit a Diverse Workforce (IRDW) program. We define peer mentoring as informal mentoring that happens between individuals to promote career success. This project is in response to “White Librarianship in Blackface: Diversity Initiatives in LIS” in which one of Hathcock’s criticisms of current diversity initiatives is the focus on increasing numbers without addressing long-term retention.

Methodology: The project was conducted through …


The Anatomy Of The Human Rights Framework For Intellectual Property, Peter K. Yu Jan 2016

The Anatomy Of The Human Rights Framework For Intellectual Property, Peter K. Yu

Faculty Scholarship

Since the U.N. Sub-Commission on the Promotion and Protection of Human Rights adopted Resolution 2000/7 on "Intellectual Property Rights and Human Rights" more than fifteen years ago, a growing volume of literature has been devoted to the debates on the human rights limits to intellectual property rights, intellectual property and human rights, and intellectual property as human rights. Commentators, myself included, have also called for the development of a human rights framework for intellectual property. Thus far, very few commentators have explored the place of patent rights in this framework. Very little research, if any, has also been devoted to …


A Bipartisan Tax Reform?, Reuven S. Avi-Yonah Jan 2016

A Bipartisan Tax Reform?, Reuven S. Avi-Yonah

Articles

A Bipartisan Tax Reform?By Reuven S. Avi-YonahIf one listens to what Democratic and Republicancandidates for president are saying on the cam-paign trail, it would appear that the chances for taxreform in 2017 and beyond are minimal. A biparti-san approach is essential for tax reform to passbecause even if there are majorities from the presi-dent’s party in both houses, major tax reform wouldnot likely get through the Senate without 60 votes.But the parties seem very far apart on tax reform.Democrats are focused on using the tax system toreduce inequality and are determined to raise thetax rates at the top of the …


Back To 1913?: The Ryan Blueprint And Its Problems, Reuven S. Avi-Yonah Jan 2016

Back To 1913?: The Ryan Blueprint And Its Problems, Reuven S. Avi-Yonah

Articles

From the Revolutionary War to the late 19th century, the federal government was financed primarily through regressive tariffs on imported goods. The exception was the income tax enacted during the national emergency of the Civil War, which was allowed to expire in 1872. The rise of an industrial economy in the post- Civil War era led to significant increases in inequality, which the tariffs exacerbated by falling primarily on the working class. ‘‘Robber barons’’ like J.P. Morgan, Andrew Carnegie, and John D. Rockefeller did not consume most of their income, and their intangible wealth avoided state-level personal property taxes as …


Disparate Impact And The Role Of Classification And Motivation In Equal Protection Law After Inclusive Communities, Samuel Bagenstos Jan 2016

Disparate Impact And The Role Of Classification And Motivation In Equal Protection Law After Inclusive Communities, Samuel Bagenstos

Articles

At least since the Supreme Court’s 2009 decision in Ricci v. DeStefano, disparate-impact liability has faced a direct constitutional threat. This Article argues that the Court’s decision last Term in Texas Department of Housing and Community Affairs v. Inclusive Communities Project, Inc., which held that disparate-impact liability is available under the Fair Housing Act, has resolved that threat, at least for the time being. In particular, this Article argues, Inclusive Communities is best read to adopt the understanding of equal protection that Justice Kennedy previously articulated in his pivotal concurrence in the 2007 Parents Involved case—which argued that …


Confronting Power In Public Law, Kate Andrias Jan 2016

Confronting Power In Public Law, Kate Andrias

Articles

In his important and provocative Foreword, Professor Daryl Levinson criticizes American constitutional law for failing to attend sufficiently to questions of power, which he defines as “the ability to effect substantive policy outcomes by influencing what the government will or will not do.” As Levinson details, structural constitutional law has focused on how power is distributed among governmental institutions. It has not consistently or adequately considered how power is — or should be — distributed among social groups. Ultimately, Levinson suggests that the narrow focus of separation of powers law and theory on “equalizing the power of government institutions” lacks …


Robust Multi-Criteria Optimal Fuzzy Control Of Discrete-Time Nonlinear Systems, Xin Wang, Edwin E. Yaz Jan 2016

Robust Multi-Criteria Optimal Fuzzy Control Of Discrete-Time Nonlinear Systems, Xin Wang, Edwin E. Yaz

Electrical and Computer Engineering Faculty Research and Publications

This paper presents a novel fuzzy control design of discrete-time nonlinear systems with multiple performance criteria. The purpose behind this work is to improve the traditional fuzzy controller performance to satisfy several performance criteria simultaneously to secure quadratic optimality with an inherent stability property together with a dissipativity type of disturbance reduction. The Takagi–Sugeno-type fuzzy model is used in our control system design. By solving a linear matrix inequality at each time step, the optimal control solution can be found to satisfy mixed performance criteria. The effectiveness of the proposed technique is demonstrated by simulation of the control of the …


A Computationally Efficient Method For Calculation Of Strand Eddy Current Losses In Electric Machines, Alireza Fatemi, Dan M. Ionel, Nabeel Demerdash, Dave A. Staton, Rafal Wrobel, Yew Chuan Chong Jan 2016

A Computationally Efficient Method For Calculation Of Strand Eddy Current Losses In Electric Machines, Alireza Fatemi, Dan M. Ionel, Nabeel Demerdash, Dave A. Staton, Rafal Wrobel, Yew Chuan Chong

Electrical and Computer Engineering Faculty Research and Publications

In this paper, a fast finite element (FE)-based method for the calculation of eddy current losses in the stator windings of randomly wound electric machines with a focus on fractional slot concentrated winding (FSCW) permanent magnet (PM) machines will be presented. The method is particularly suitable for implementation in large-scale design optimization algorithms where a qualitative characterization of such losses at higher speeds is most beneficial for identification of the design solutions which exhibit the lowest overall losses including the ac losses in the stator windings. Unlike the common practice of assuming a constant slot fill factor, sf, for all …


Right-Sided Congenital Diaphragmatic Hernia And Myelomeningocele: A Rare Association, Syed Rehan Ali, Shakeel Ahmed Jan 2016

Right-Sided Congenital Diaphragmatic Hernia And Myelomeningocele: A Rare Association, Syed Rehan Ali, Shakeel Ahmed

Department of Paediatrics and Child Health

Congenital diaphragmatic hernia (CDH) is a rare birth defect with a prevalence of < 0.5 per 1,000 live births. Majority of these defects are left-sided as most studies suggest that frequency of right-sided CDH was 10% of the total. The association of CDH with myelomeningocele (MMC) is extremely rare; as in Sweed's study of 116 consecutive cases of CDH, the incidence of associated MMC with CDH was stated as 4.3%. There has been one previous case report of leftsided CDH, MMC and hydrocephalus prenatally diagnosed; but to the best of authors' knowledge, this is the first reported case of the above constellation with a right-sided CDH diagnosed prenatally.


Atrial Thrombus In A Premature Newborn Following Cardio-Pulmonary Resuscitation, Syed Rehan Ali, Shakeel Ahmed, Nadeem Aslam, Heeramani Lohana Jan 2016

Atrial Thrombus In A Premature Newborn Following Cardio-Pulmonary Resuscitation, Syed Rehan Ali, Shakeel Ahmed, Nadeem Aslam, Heeramani Lohana

Department of Paediatrics and Child Health

Critically ill newborns, whether term or preterm, are at great risk for developing symptomatic thromboembolic disease. Comorbidities like inflammation, DIC, fluctuations in cardiac output, congenital heart disease, as well as central venous or arterial catheters, are the predisposing risk factors. Clinically symptomatic or asymptomatic cases are usually picked up by echocardiography, usually done for other indications. Management usually comprises of observation, heparin therapy, thrombo-embolectomy, and catheter directed revascularization. We present a case of premature neonate who developed thrombus at inter-atrial septum as a possible consequence of cardiopulmonary resuscitation, detected by echocardiography. Conversely, there is always a possibility of paradoxical emboli …


Mumps Myocarditis: A Forgotten Disease?, Sheraz Hussain, Mohammad Faizan Zahid, Arshalooz J. Rahman, Mehnaz A. Atiq, S. H. Ibrahim Jan 2016

Mumps Myocarditis: A Forgotten Disease?, Sheraz Hussain, Mohammad Faizan Zahid, Arshalooz J. Rahman, Mehnaz A. Atiq, S. H. Ibrahim

Department of Paediatrics and Child Health

Mumps is an acute viral illness that follows a self-limiting course but up to 10% of cases have a complicated course with the involvement of other organ systems. Myocarditis is reported as a complication but the incidence has greatly fallen ever since the development of the mumps vaccine. A child presented to our department with parotid swelling and fever. Persistent tachycardia with irregular pulse led to further cardiac work up which showed decreased ejection fraction and raised serum cardiac enzymes, indicating myocardial damage. With ionotropic agents and supportive care, there was complete normalization of ejection fraction and serum cardiac enzyme …

Evaluation Of Solar Disinfection Of Water Intervention Delivered Through Lady Health Workers In Reduction Of Diarrheal Episodes In Under Five Children, Shabina Ariff, Ubaidullah Khan, Ali Turab, Imtiaz Hussain, Atif Habib, Tarab Mansoor, Dania Mallick, Zamir Suhag, Zaid Bhatti, Imran Ahmed, Sajid Bashir Soofi, Zulfiqar A Bhutta

Department of Paediatrics and Child Health

Background: Solar Water Disinfection (SODIS) is a simple, inexpensive and sustainable means of daily household treatment for drinking and storage of water. Globally, over a billion people lack access to safe drinking water. As many as half million under five children die annually due to diarrheal illnesses. Most of these deaths are concentrated in Africa and South Asia. Unsafe water is one of the most critical risk factors for diarrhoea. Systematic reviews indicate that interventions to improve the microbial quality of drinking water in households are effective at reducing diarrhoea illnesses and thereby contribute significantly in reducing deaths due to …


Innovation, The State And Private Enterprise: A Corporate Lawyer's Perspective, Charles M. Yablon Jan 2016

Innovation, The State And Private Enterprise: A Corporate Lawyer's Perspective, Charles M. Yablon

Articles

This is a review essay based on an important recent book, The Entrepreneurial State: Debunking Public vs. Private Sector Myths, by Mariana Mazzucato, a Professor of the Economics of Innovation. In that book, Professor Mazzucato explains how the U.S. Government, acting as an “entrepreneurial state” has made the critical investments in technologies that have given rise to multi-billion dollar new industries. Mazzucato argues that only the State currently has the funds and incentives necessary to finance the earliest and most important phases of the innovation process, investments the private sector cannot and will not make. Mazzucato’s defense of the centrality …


Hillenmeyer, "Convenience Of The Employer," And The Taxation Of Nonresidents' Incomes, Edward A. Zelinsky Jan 2016

Hillenmeyer, "Convenience Of The Employer," And The Taxation Of Nonresidents' Incomes, Edward A. Zelinsky

Articles

In Hillenmeyer v. Cleveland Board of Review, Ohio’s Supreme Court unanimously declared that Cleveland’s municipal income tax violated the Due Process Clause of the U.S. Constitution by taxing a nonresident athlete under the “games-played” method rather than the “duty-days” method. According to the Ohio court, the games-played approach overtaxed Mr. Hillenmeyer by allocating to Cleveland Mr. Hillenmeyer’s compensation from the Chicago Bears using the percentage of the Bears’ games played in Cleveland. By this approach, Cleveland taxed Mr. Hillenmeyer extraterritorially, reaching income he earned from services he performed for the Bears outside of Cleveland’s borders. Due Process, the Ohio …


Legal Capacity For All: Including Older Persons In The Shift From Adult Guardianship To Supported Decision-Making, Rebekah Diller Jan 2016

Legal Capacity For All: Including Older Persons In The Shift From Adult Guardianship To Supported Decision-Making, Rebekah Diller

Articles

For the last several decades, guardianship has been the subject of continual calls for reform, often spurred by revelations of guardian malfeasance and other abuses in the system. Recent developments in international human rights law pose a more fundamental challenge to the institution. Under Article 12 of the United Nations Convention on the Rights of Persons with Disabilities (CRPD), governments may not deprive individuals of their “legal capacity”—or right to make decisions and have those decisions recognized as legally binding—on the grounds of disability. In the wake of the CRPD, the concept of supported decision-making has gained growing acceptance as …


The Entrepreneurial Commons: Reframing The Relationship Between Intellectual Property And Entrepreneurship, Michael J. Burstein Jan 2016

The Entrepreneurial Commons: Reframing The Relationship Between Intellectual Property And Entrepreneurship, Michael J. Burstein

Articles

Reconceptualizing entrepreneurial activity as a knowledge commons leads us to ask a different set of questions than previous studies have, and to utilize a different set of methodological tools. As Part II described, existing approaches to understanding the relationship between IP and entrepreneurship focus on the firm and its reactions to various IP laws. By contrast, to the extent that the exemplar entrepreneurial activities described in Part III can be described as instances of commons governance, the analysis must necessarily be broader. The knowledge commons framework forces us to acknowledge that much of information production and dissemination depends on relationships …


A Theory Of Copyright Authorship, Christopher Buccafusco Jan 2016

A Theory Of Copyright Authorship, Christopher Buccafusco

Articles

The U.S. Constitution gives Congress the power to grant rights to “Authors” for their “Writings.” Despite the centrality of these terms to copyright jurisprudence, neither the courts nor scholars have provided coherent theories about what makes a person an author or what makes a thing a writing. This article articulates and defends a theory of copyrightable authorship. It argues that authorship involves the intentional creation of mental effects in an audience. A writing, then, is any fixed medium capable of producing mental effects. According to this theory, copyright may attach to the original, fixed, and minimally creative form or manner …


The Day Doctrine Died: Private Arbitration And The End Of Law, Myriam E. Gilles Jan 2016

The Day Doctrine Died: Private Arbitration And The End Of Law, Myriam E. Gilles

Articles

This story begins in 1980, when a budding anti-lawsuit movement found an energetic champion in a new conservative President. Over time, the movement became a dominant feature of political life, as its narrative of activist judges, jackpot justice, and a thriving lawsuit industry stirred partisan passions. And yet, some thirty years on, it is clear that the primary legacy of the anti-lawsuit movement is the movement itself--not legislative achievements, which have been few and far between, but committed adherents, including future Supreme Court Justices, lower court judges, and business leaders.

Meanwhile, and also in the early 1980s, federal courts began …


A Histopathological Outlook On Nephrotic Syndrome: A Pediatric Perspective, M K. Arif, M Arif, N Amjad Jan 2016

A Histopathological Outlook On Nephrotic Syndrome: A Pediatric Perspective, M K. Arif, M Arif, N Amjad

Department of Paediatrics and Child Health

The developing world is observing changing histopathological patterns of idiopathic nephrotic syndrome (INS). However, the true burden of non-minimal change disease (non-MCD) presenting as INS remains unestimated owing to a paucity of data on renal biopsies. Data were collected from January 2006 to June 2014 on 75 children up to 16 years of age who underwent renal biopsies for INS. Mean age at biopsy was 11.2 ± 3.7 years. The male to female ratio was 1.5:1. A total of 25 (33.3%) children were steroid sensitive, 36 (48%) were steroid resistant, 10 (13.3%) were steroid dependent and 4 (5.3%) came with …


Sensor-Based Estimation Of Btex Concentrations In Water Samples Using Recursive Least Squares And Kalman Filter Techniques, Karthick Sothivelr, Florian Bender, Fabien Josse, Edwin E. Yaz, Antonio J. Ricco Jan 2016

Sensor-Based Estimation Of Btex Concentrations In Water Samples Using Recursive Least Squares And Kalman Filter Techniques, Karthick Sothivelr, Florian Bender, Fabien Josse, Edwin E. Yaz, Antonio J. Ricco

Electrical and Computer Engineering Faculty Research and Publications

This work investigates sensor signal processing approaches that can be used with a sensor system for direct on-site monitoring of groundwater, enabling detection and quantification of BTEX (benzene, toluene, ethylbenzene and xylene) compounds at μg/L (ppb) concentrations in the presence of interferents commonly found in groundwater. A model for the sensor response to water samples containing multiple analytes was first formulated based on experimental results. The first signal processing approach utilizes only RLSE (recursive least squares estimation) whereas the second, a two-step processing technique, utilizes both RLSE and bank of Kalman filters for the estimation process. The estimation techniques were …


Effect Of Mobile Phone Text Messages Reminders On Uptake Of Routine Immunization Among Children In Pakistan- Study Protocol For A Randomized Clinical Trial, Abdul Momin Kazi, Murtaza Ali, Khurram Zubair, Hussain Kalimuddin, Syed Asad Ali Jan 2016

Effect Of Mobile Phone Text Messages Reminders On Uptake Of Routine Immunization Among Children In Pakistan- Study Protocol For A Randomized Clinical Trial, Abdul Momin Kazi, Murtaza Ali, Khurram Zubair, Hussain Kalimuddin, Syed Asad Ali

Department of Paediatrics and Child Health

Introduction: Routine Immunization (RI) is considered one of the best public health interventions to decrease child morbidity and mortality. The RI coverage in Pakistan is still well below the desired level, leading to continued polio transmission, large measles outbreaks and thousands of deaths from vaccine-preventable illnesses. Different innovative and cost effective strategies are required to look into for enhancement in vaccination uptake and coverage. We plan to test the effectiveness of reminders to parents/caregivers on cell phones through short messaging system (SMS) in improving vaccine uptake and on-time routine immunization for children in Pakistan.
Methods and Analysis: A parallel-randomized controlled …

On The Analytical Formulation Of Excess Noise In Avalanche Photodiodes With Dead Space, Erum Jamil, Jeng Shiuh Cheong, J.P.R. David, Majeed M. Hayat Jan 2016

On The Analytical Formulation Of Excess Noise In Avalanche Photodiodes With Dead Space, Erum Jamil, Jeng Shiuh Cheong, J.P.R. David, Majeed M. Hayat

Electrical and Computer Engineering Faculty Research and Publications

Simple, approximate formulas are developed to calculate the mean gain and excess noise factor for avalanche photodiodes using the dead-space multiplication theory in the regime of small multiplication width and high applied electric field. The accuracy of the approximation is investigated by comparing it to the exact numerical method using recursive coupled integral equations and it is found that it works for dead spaces up to 15% of the multiplication width, which is substantial. The approximation is also tested for real materials such as GaAs, InP and Si for various multiplication widths, and the results found are accurate within ∼ …
