Antioxidant Activities Of The Extracts And Components Of Teucrium Orientale L. Var. Orientale, Ahmet Çakir, Ahmet Mavi̇, Cavi̇t Kazaz, Ali̇ Yildirim, Ömer İrfan Küfrevi̇oğlu

Turkish Journal of Chemistry

The effects of the developing stages of Teucrium orientale L. var. orientale on the antioxidant and DPPH radical scavenging activities of the extracts obtained with different organic solvents were investigated. The aerial parts of the plant samples were collected at the budding, flowering and vegetative stages and then the plant samples were extracted separately with petroleum ether, chloroform, acetone and methanol. The antioxidant activities of the extracts were evaluated using 2 different tests: the thiocyanate method and scavenging of the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The acetone and methanol extracts of all of the harvesting stages and chloroform extracts of the budding …

Fear Of Democracy: A Cultural Evaluation Of Sunstein On Risk, Donald Braman, Dan M. Kahan, Paul Slovic, John Gastil

GW Law Faculty Publications & Other Works

What dynamics shape public risk perceptions? What significance should such perceptions have in the formation of risk regulation? In Laws of Fear: Beyond the Precautionary Principle (2005), Cass Sunstein catalogs a variety of cognitive and social mechanisms that he argues inflate public estimations of various societal risks. To counter the impact of irrational public fears, he advocates delegation of authority to politically insulated experts using economic cost-benefit analysis. Missing from Sunstein's impressive account, however, is any attention to the impact of cultural cognition, the tendency of individuals to form risk perceptions that reflect and reinforce their cultural worldviews. Relying on …

Planning Options For The Daily Care Of A Minor In The Event Of An Adult's Incapacity Or Death, Naomi R. Cahn

GW Law Faculty Publications & Other Works

While most children grow up in their families of origin with at least one of their parents, what happens when the parents die or are incapacitated? While they are alive, parents are presumed to be the legal guardians for their children, and if one dies or has had his/her parental rights terminated, then the surviving parent is generally the sole legal guardian. Even if that parent remarries, the stepparent is not the legal parent.

As this chapter shows, parents can give to other adults some of their legal caretaking responsibilities while they are still competent. There are three different methods …

The Relevance Of The Nlra And Labor Organizations In The Post-Industrial Global Economy, Charles B. Craver

GW Law Faculty Publications & Other Works

As the United States continues to transition from a manufacturing to a post-industrial service-oriented economy that is directly affected by global competition, the strength of domestic labor organizations has declined and private sector union membership has fallen to below 8 percent. Most unions continue to behave like the craft and industrial organizations of the mid-1900s. They employ appeals that once worked well for blue collar manufacturing workers to appeal to new-age white collar and service personnel who view traditional unionization as working class. If labor organizations hope to appeal to twenty-first century employees, they must devise strategies that will resonate …

Privacy Issues Affecting Employers, Employees, And Labor Organizations, Charles B. Craver

GW Law Faculty Publications & Other Works

Privacy issues arise regularly in employment environments. Employers frequently assert privacy rights when denying non-employee union organizers access to employment premises and limiting the distribution of union literature or the solicitation of authorization cards by current employees. On the other hand, when employers desire to monitor employee computer usage on firm computers to be sure they are not accessing inappropriate sites or engaging in other inappropriate electronic behavior, they give short shrift to employee privacy claims. When employer premises are open to the general public, non-employee access to external areas such as parking lots might provide an appropriate accommodation between …

Engineering A Deal: Toward A Private Ordering Solution To The Anticommons Problem, F. Scott Kieff, Troy A. Paredes

GW Law Faculty Publications & Other Works

The problems of the intellectual property ("IP") anticommons are infamous. Many people fear that the potential for vast numbers of IP rights to cover a single good or service will prevent an enterprise from even attempting to launch a business for fear of being unduly taxed or retarded or simply held up. This Article offers a solution based on private ordering within the context of existing laws. This approach uses a limited liability entity structured so that IP owners are given an actual stake in the operating business and thus an incentive to participate in the enterprise; and yet at …

Social Play In Kakapo (Strigops Habroptilus) With Comparisons To Kea (Nestor Notabilis) And Kaka (Nestor Meridionalis), Judy Diamond, Daryl Eason, Clio Reid, Alan B. Bond

Papers in Behavior in Biological Sciences

The play behavior of the critically endangered kakapo (Strigops habroptilus; Aves: Psittaciformes: Psittacidae) is here compared to that of its closest relatives, the kea (Nestor notabilis) and the kaka (Nestor meridionalis). Contrasting kakapos, which are relatively solitary, with the more social Nestor parrots provides an attractive test of the relative contributions of phylogeny and sociality to the evolution of play. Overlapping cluster analysis of play sequences using a hypergeometric similarity metric indicated that kakapo play is generally less complex, lacking the intensity, duration, structure, and reciprocity of play in the Nestor parrots. Kakapos have …

Effects Of Husbandry Parameters On The Life-History Traits Of The Apple Snail, Marisa Cornuarietis: Effects Of Temperature, Photoperiod, And Population Density, John Aufderheide, Ryan Warbritton, Nadine Pounds, Sharon File-Emperador, Charles Staples, Norbert Caspers, Valery E. Forbes

Valery Forbes Publications

These experiments are part of a larger study designed to investigate the influence of husbandry parameters on the life history of the apple snail, Marisa cornuarietis. The overall objective of the program is to identify suitable husbandry conditions for maintaining multigeneration populations of this species in the laboratory for use in ecotoxicological testing. In this article, we focus on the effects of photoperiod, temperature, and population density on adult fecundity and juvenile growth. Increasing photoperiod from 12 to 16 h of light per day had no effect on adult fecundity or egg hatching and relatively minor effects on juvenile growth …

Ecology In A Cost-Benefit Society: The Issues, Valery E. Forbes, Peter Calow

Valery Forbes Publications

Is there a role for ecology in a cost-benefit society? As a prelude to a collection of papers arising from a conference on this theme held at Roskilde University in June 2004, this paper summarizes divergent approaches to public policy decision making. Whether based on strict cost-benefit analysis or wide-ranging discussion, we make the point that decisions need to be informed by an understanding of the causes behind environmental problems and their consequences, through impaired ecosystem services, on the economy. Taking this forward will require forums that bring ecologists, economists, and regulators into active and constructive dialogue.

Influence Of Biotransformation On Trophic Transfer Of The Pah, Fluoranthene, Annemette Palmqvist, Lene Juel Rasmussen, Valery E. Forbes

Valery Forbes Publications

The persistence of polycyclic aromatic hydrocarbons (PAHs) in marine sediments may be influenced by benthic invertebrate bioturbation. Through processes such as deposit-feeding and enhancement of microbial metabolic activity PAHs may be remobilized from the sediment compartment, and either transferred to organisms at higher trophic levels or to the overlying water column, both processes inevitably changing the bioavailability of the PAH. Accumulation of contaminants from one level in the food chain to the next depends on feeding rate and assimilation efficiency, two factors that basically vary with food quality and contaminant type. Though it is generally believed that pre-consumptive biotransformation will …

Justice Rehnquist And The Dismantling Of Environmental Law, Robert L. Glicksman, James May

GW Law Faculty Publications & Other Works

Chief Justice William H. Rehnquist was uniquely situated to have a profound impact on the development of federal environmental law - both because of the overlap of his tenure with the development of the field of environmental law and because of his four-decade tenure on the U.S. Supreme Court, more than one-half of which was as Chief Justice. Before his death on September 3, 2005, Rehnquist heard the vast majority of the Court`s environmental cases during the modern environmental era, penning opinions in 25% of them, and affording him an opportunity to shape environmental law, especially during its formative years, …

Using Ex Post Evaluations To Improve The Performance Of Competition Policy Authorities, William E. Kovacic

GW Law Faculty Publications & Other Works

Competition policy is a work in progress. Charting the future course of competition policy can benefit heavily from looking back and asking two fundamental questions. First, did the agency’s interventions produce good results? Second, did the agency’s managerial processes help ensure that the agency selected initiatives that would yield good outcomes? This article discusses how government competition authorities might use ex post evaluations of enforcement decisions, operational mechanisms, and organizational design to improve the quality of their work. Preparing performance measures and conducting evaluations provide valuable tools for answering critical questions about the administration of competition policy.

The article also …

Estoppel And Textualism, Gregory E. Maggs

GW Law Faculty Publications & Other Works

How might judges who purport to adhere to textualism justify their use of estoppel to affect the application of statutes that say nothing about estoppel? This essay addresses this question. It considers six possible arguments that courts have made or might make to rationalize the recognition of unwritten exceptions to statutes in the name of estoppel. These arguments include the following: (1) Even though the statutory provision at issue says nothing about estoppel, some other legislation expressly authorizes courts to invoke equitable principles, including estoppel; (2) The legislation contains an implied term authorizing the application of estoppel principles; (3) Courts …

The Corporate Lawyer And 'The Perjury Trilemma', Thomas D. Morgan

GW Law Faculty Publications & Other Works

This paper extends Monroe Freedman's idea of the criminal lawyer's "perjury trilemma" to current issues faced by corporate lawyers dealing with perceived pressures on the attorney-client privilege. The duties of criminal defense and corporate lawyers are more similar than they often seem. Corporate lawyers' duties of honesty in dealing with third parties are closely analogous to criminal lawyers' duties of honesty in dealing with a court. Both sets of lawyers also have an important interest in fostering open communications with their clients. Where their situations differ is not with respect to lawyer obligations but with respect to their clients' rights. …

Purification And Initial Biochemical Characterization Of Atp:Cob(I)Alamin Adenosyltransferase (Eutt) Enzyme Of Salmonella Enterica, Nicole R. Baun, Jorge C. Escalante-Semerena

Department of Biochemistry: Faculty Publications

ATP:cob(I)alamin adenosyltransferase (EutT) of Salmonella

enterica was overproduced and enriched to ~70% homogeneity,

and its basic kinetic parameters were determined. Abundant

amounts of EutT protein were produced, but all of it remained

insoluble. Soluble active EutT protein (~70% homogeneous) was

obtained after treatment with detergent. Under conditions in which

cobalamin (Cbl) was saturating, _Km(ATP) = 10 µM, k_cat = 0.03 s^-1,

and V_max = 54.5 nM min^-1. Similarly, under conditions in which

MgATPwas saturating,K_m(Cbl) = 4.1µM, k_cat = 0.06 s^-1, andV_max= …

Protein Binding Site Prediction Using An Empirical Scoring Function, Shide Liang, Chi Zhang, Song Liu, Yaoqi Zhou

School of Biological Sciences: Faculty Publications

Most biological processes are mediated by interactions between proteins and their interacting partners including proteins, nucleic acids and small molecules. This work establishes a method called PINUP for binding site prediction of monomeric proteins. With only two weight parameters to optimize, PINUP produces not only 42.2% coverage of actual interfaces (percentage of correctly predicted interface residues in actual interface residues) but also 44.5% accuracy in predicted interfaces (percentage of correctly predicted interface residues in the predicted interface residues) in a cross validation using a 57-protein dataset. By comparison, the expected accuracy via random prediction (percentage of actual interface residues in …

A Taxonomy Of Privacy, Daniel J. Solove

GW Law Faculty Publications & Other Works

Privacy is a concept in disarray. Nobody can articulate what it means. As one commentator has observed, privacy suffers from an embarrassment of meanings. Privacy is far too vague a concept to guide adjudication and lawmaking, as abstract incantations of the importance of privacy do not fare well when pitted against more concretely-stated countervailing interests.

In 1960, the famous torts scholar William Prosser attempted to make sense of the landscape of privacy law by identifying four different interests. But Prosser focused only on tort law, and the law of information privacy is significantly more vast and complex, extending to Fourth …

A Brief History Of Information Privacy Law, Daniel J. Solove

GW Law Faculty Publications & Other Works

This book chapter provides a brief history of information privacy law in the United States from colonial times to the present. It discusses the development of the common law torts, Fourth Amendment law, the constitutional right to information privacy, numerous federal statutes pertaining to privacy, electronic surveillance laws, and more. It explores how the law has emerged and changed in response to new technologies that have increased the collection, dissemination, and use of personal information.

A Model Regime Of Privacy Protection, Daniel J. Solove

GW Law Faculty Publications & Other Works

A series of major security breaches at companies with sensitive personal information has sparked significant attention to the problems with privacy protection in the United States. Currently, the privacy protections in the United States are riddled with gaps and weak spots. Although most industrialized nations have comprehensive data protection laws, the United States has maintained a sectoral approach where certain industries are covered and others are not. In particular, emerging companies known as "commercial data brokers" have frequently slipped through the cracks of U.S. privacy law. In this article, the authors propose a Model Privacy Regime to address the problems …

The Wall And The Law: A Tale Of Two Judgements, Susan M. Akram, S. Michael Lynk

Faculty Scholarship

The seminal rulings in 2004 by the International Court of Justice and the Israeli High Court on the legality of the wall/barrier that Israel is building through the occupied West Bank and East Jerusalem provide a study in contrast. While both judgements were critical of the wall/barrier, their judicial approaches and legal conclusions were strikingly divergent, particularly given that the two courts were purporting to rely upon the same principles of international law. The judgements also elicited quite different political and diplomatic reactions, especially among the parties most involved in the Israel/Palestine conflict. This article explores the legal analysis and …

Sentencing For The 'Crime Of Crimes': The Evolving 'Common Law' Of Sentencing Of The International Criminal Tribunal For Rwanda, Robert D. Sloane

Faculty Scholarship

Absent much prescriptive guidance in its Statute or other positive law, the International Criminal Tribunal for Rwanda (ICTR) has been developing, in effect, a 'common law' of sentencing for the most serious international crimes: genocide and crimes against humanity. While it remains, as the Appeals Chamber has said, premature to speak of an emerging 'penal regime', and the coherence in sentencing practice that this denotes, this comment offers some preliminary reflections on the substantive law and process of sentencing as it has evolved through ICTR practice. Above all, I argue, sentencing must, but has not yet, become an integral part …

Bioterror And “Bioart”: A Plague O' Both Your Houses, George J. Annas

Faculty Scholarship

Since September 11, 2001, the threat of bioterrorism has caused Congress and the President to dramatically increase research funding for countermeasures, including funding for new biosecurity laboratories. The new kind of war against non-state actors who use terror to intimidate populations has also made the creation of new ethical and legal rules for researchers seem critical. New laws have been passed, and there have been proposals for new codes of ethics for bioterrorism-related research. Almost five years after September 11, however, the outcome of the development of new research rules remains uncertain.

Intelligent Judging: Evolution In The Classroom And The Courtroom, George J. Annas

Faculty Scholarship

Religious arguments have permeated debates on the role of the law in medical practice at the beginning and the end of life. But nowhere has religion played so prominent a role as in the century-old quest to banish or marginalize the teaching of evolution in science classes. Nor has new genetics research that supports evolutionary theory at the molecular level dampened antievolution sentiment. Requiring public-school science teachers to teach specific religion-based alternatives to Darwin's theory of evolution is just as bad, in the words of political comedian Bill Maher, as requiring obstetricians to teach medical students the alternative theory that …

Spatial Analyses Of Trophic Linkages Between Basins In The Great Salt Lake, Wayne A. Wurtsbaugh, David Naftz, Shane Bradt

Watershed Sciences Faculty Publications

Although the Great Salt Lake is frequently treated as if it were a single body of water, the natural bays and transportation causeways have divided it into a system of four bays. The bays, however, do not function independently because water, nutrients and other contaminants flow between them. The purpose of our study was to analyze the water quality in three of the bays (Farmington, Bear River and Gilbert), to determine fluxes of nutrients between them, and to determine how this was influencing brine shrimp populations in the lake. Discharge and nutrient concentrations were measured at constrictions separating the three …

Sounding Of The Atmosphere Using Broadband Emission Radiometry (Saber): Sensor Design, Performance, And Lessons Learned, Steven B. Brown, Mark Jensen, Scott Jensen, Glen Hansen, Lorin Zollinger, Roy Esplin, James B. Miller

Space Dynamics Laboratory Publications

The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument, a 10-channel infrared (1.27 - 16.9 μm) radiometer, was launched on the TIMED (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) satellite in December 2001 from Vandenburg Air Force Base. SABER is being used to measure earthlimb emissions and to characterize infrared radiation, allowing calculation of cooling rates and determination of composition and temperature profiles in the mesosphere, lower thermosphere, and ionosphere (60-180 km). The SABER telescope is an on-axis Cassegrain design with a picket-fence tuning fork chopper at the first focus and a clamshell re-imager to focus the image on …

Using Citation Data To Improve Retrieval From Medline, Elmer V Bernstam, Jorge R Herskovic, Yindalon Aphinyanaphongs, Constantin F Aliferis, Madurai G Sriram, William R Hersh

Faculty, Staff and Student Publications

OBJECTIVE: To determine whether algorithms developed for the World Wide Web can be applied to the biomedical literature in order to identify articles that are important as well as relevant. DESIGN AND MEASUREMENTS A direct comparison of eight algorithms: simple PubMed queries, clinical queries (sensitive and specific versions), vector cosine comparison, citation count, journal impact factor, PageRank, and machine learning based on polynomial support vector machines. The objective was to prioritize important articles, defined as being included in a pre-existing bibliography of important literature in surgical oncology. RESULTS Citation-based algorithms were more effective than noncitation-based algorithms at identifying important articles. …
