Feasibility Of Brief Hospital-Based Interventions For Postpartum Depression : Effects On Depressive Symptoms, Perceived Support, & Treatment Utilization, Sabra N. Abboud

PCOM Psychology Dissertations

It is estimated that 10-20% of childbearing women develop postpartum depression (PPD), affecting up to 400,000 women in the United States each year. As many an 82% of women diagnosed with PPD decline recommended treatment, primarily due to a lack of knowledge about PPD, to societal stigma and to practical barriers. The objective of this study is to evaluate the feasibility of conducting a large-scale study examining the impact of screening measures and a supportive approach immediately postpartum on utilization of recommended care, levels of depression and perceived social support. Women were randomly assigned (N=40) on a maternity unit to …

Rooted: A New Generation Of Farmers And Ranchers In Montana, Beth Jeannette Gibson

Graduate Student Theses, Dissertations, & Professional Papers

Rooted tells the stories of a new generation of farmers and ranchers in Montana through still photography and written profiles; the project is the result of 13 site visits and interviews. I define “new farmer” as a person operating their own agricultural business for 10 years or fewer, though this definition gets blurred and complicated when referring to people who return to their family’s farm or ranch. Admittedly, this project features only a few of the beginning farmers and ranchers in Montana. My intention is not to provide an exhaustive study of the next generation of farmers and ranchers in …

A Higher-Order Spectro-Temporal Integration Model For Predicting Signal Audibility, Qing Yang, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

A higher-order model to determine audibility of audio signals is presented. Previous models have been energy based (second order) and adequate only for stationary, narrow-band signals. Music, speech and other audio signals are nonstationary and wideband so traditional energy models poorly predict the audibility of these sounds. The predictions from the higher-order model are compared to actual subjective listening tests to show that the higher order, wide-band technique outperforms previous models. ©2010 IEEE.

Discrete-Time Multi-Scale Systems, Daniel Alpay, Mamadou Mboup

Mathematics, Physics, and Computer Science Faculty Articles and Research

We introduce multi-scale filtering by the way of certain double convolution systems. We prove stability theorems for these systems and make connections with function theory in the poly-disc. Finally, we compare the framework developed here with the white noise space framework, within which a similar class of double convolution systems has been defined earlier.

Limit On Continuous Neutrino Emission From Neutron Stars, Itzhak Goldman, Shmuel Nussinov

Mathematics, Physics, and Computer Science Faculty Articles and Research

The timing data of the binary pulsar PSR1913+16, are used to establish an upper limit on the rate of continuous neutrino emission from neutron stars. Neutrino emission from each of the neutron stars of the binary system, increases the star binding energy and thus translates to a decrease in their masses. This in turn implies an increase with time of the binary period. Using the pulsar data we obtain an upper limit on the allowed rate of mass reduction: vertical bar M vertical bar < 1.1 x 10(-12) yr(-1) M, where M is the total mass of the binary. This constrains exotic nuclear equations of state that predict continuous neutrino emissions. The limit applies also to other channels of energy loss, e. g. axion emission. Continued timing measurements of additional binary pulsars, should yield a stronger limit in the future.

Effectiveness Of Deer Repellents In Connecticut, Jeffrey S. Ward, Scott C. Williams

Human–Wildlife Interactions

Browsing by overabundant herds of white-tailed deer (Odocoileus virginianus) can cause significant economic damage to agricultural crops and landscape plantings. In many instances, for both commercial growers and homeowners, commercially available repellents may be an appealing alternative to physical exclusion and lethal control of animals. We tested 10 different commercially-available repellents (Chew-Not®, Deer Off®, Deer-Away® Big Game Repellent, Plantskydd®, Bobbex®, Liquid Fence®, Deer Solution®, Hinder®, Repellex® systemic tablets, and coyote urine) on yews (Taxus cuspidata Densiformis) at 2 different locations in Connecticut. The study included both positive (fence) and negative (no treatment) controls. We planted yews in …

Driver Knowledge, Beliefs, And Attitudes About Deer–Vehicle Collisions In Southern Michigan, Alix Marcoux, Shawn J. Riley

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are one of the most frequent and costly human– wildlife conflict throughout the range of white-tailed deer (Odocoileus virginianus). We conducted a self-administered, mail-back survey of Michigan drivers to determine: (1) driver attitudes and knowledge about DVCs; (2) reporting rates of DVCs; and (3) effects of being in a DVC on attitudes toward desired deer population levels. From a sample of 3,600 randomly selected licensed drivers >18 years of age in southeast Michigan, we obtained 1,653 completed questionnaires (48% response rate). Although 18% of respondents reported experiencing >1 DVC within 5 years of the survey …

European Starling Preferences For Bait Substrates Used In Drc-1339 Applications, H. Jeffrey Homan, George M. Linz, Scott Beckerman, Anthony G. Duffiney, Thomas D. Halstead

Human–Wildlife Interactions

Additional bait substrates for the avicide, DRC-1339 Concentrate (3-chloro-4- methylaniline hydrochloride), could provide USDA/Wildlife Services with more fl exibility when managing nuisance populations of European starlings (Sturnus vulgaris) at livestock facilities. From January 11 to 21, 2008, we conducted 11 2-choice preference tests with 6 bait types at a feedlot in central Kansas. The baits included cracked corn mixed with lard (2 concentrations), 2 forms of distiller’s grain (wet powder and pellets), 2 types of livestock feed (calf-starter pellet and sweet-feed mix), and a custom-produced poultry pellet (carrier pellet) made by USDA specifically for baiting starlings. We evaluated …

An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer

Human–Wildlife Interactions

Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the …

Metapopulation Dynamics Of Mid-Continent Lesser Snow Geese: Implications For Management, Lise M. Aubry, Robert F. Rockwell, David N. Koons

Human–Wildlife Interactions

The rapid increase in abundance of lesser snow goose (LSG; Chen caerulescens caerulescens) numbers and their devastating effects on arctic and subarctic habitats has inspired much research on the use of population models for defining appropriate management policies. We use the not yet considered metapopulation approach to examine the elasticity of mid-continent LSG population dynamics to changes in underlying vital rates to determine whether management efforts aimed at decreasing burgeoning numbers should be reevaluated. After considering a variety of geographic scenarios in the metapopulation model, we found that changes in survival would still have a larger impact on population …

Bulldozers And Blueberries: Managing Fence Damage By Bare-Nosed Wombats At The Agricultural–Riparian Interface, Philip Borchard, Ian A. Wright

Human–Wildlife Interactions

Fence damage by bare-nosed wombats (Vombatus ursinus) can be a serious problem for farmers wishing to reduce herbivory by other herbivores on valuable crops. We investigated the effectiveness of exclusion fencing to prevent the incursion of unwanted native and feral herbivores and the use of swinging gates designed to allow wombats to pass through the fence without having to damage it. We also examined the temporal response of animals toward exclusion fencing and wombat gates. The 10-month study took place on the interface between natural riparian vegetation and a 22-ha blueberry (Vaccinium corymbosum) orchard in southeastern …

Bullet Fragmentation And Lead Deposition In White-Tailed Deer And Domestic Sheep, Marrett D. Grund, Louis Cornicelli, Leah T. Carlson, Erika A. Butler

Human–Wildlife Interactions

In February 2008, a private physician in North Dakota radiographed hunterharvested venison and found that 60 of 100 packages contained metal fragments. This discovery had implications for public-funded venison donation programs, and it prompted several Midwest states to examine their programs. Approximately 500,000 deer hunters harvest >200,000 deer annually in Minnesota, and the state has a donation program similar to North Dakota’s program. Therefore, we analyzed fragmentation patterns and lead deposition in carcasses of 8 white-tailed deer (Odocoileus virginianus) and 72 domestic sheep (Ovis aries). We fired 5 different bullet types from centerfire rifles, and we …

Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, Troy M. Radtke, Charles D. Dieter

Human–Wildlife Interactions

Geese, especially when they are flightless, can cause significant crop damage. We determined the effects of shoreline characteristics on foraging site selection by flightless Canada geese (Branta canadensis) in South Dakota. Distance from edge of crop field to wetland and visual obstruction by vegetation were important determinants of pathway selection by geese. Geese used crop fields for foraging that were closer to water than unused fields. Geese accessed those fields along pathways with less visual obstruction by vegetation than unused pathways. Our data suggest that this distance of crops to wetlands is the most important shoreline characteristic determining …

Survival And Harvest Characteristics Of Giant Canada Geese In Eastern South Dakota, 2000–2004, Charles D. Dieter, Jeffrey S. Gleason, Bobby J. Anderson, Spencer Vaa, Paul W. Mammenga

Human–Wildlife Interactions

The population of giant Canada geese (Branta canadensis maxima) in eastern South Dakota has increased substantially since reintroduction efforts began in the 1960s. Breeding population estimates of Canada geese exceeded the population management objective of the South Dakota Game, Fish and Parks by the mid-1990s and has continued to increase at an estimated rate of 3 to 5% per year. Goose-related crop damage complaints have also increased. In 1996, a September hunting season (September 1 to 15) was implemented in 10 counties in eastern South Dakota and was expanded in 2000 to include most of eastern South Dakota. …

Fate Of Captive-Reared And Released Mallards On Eastern Long Island, New York, Carrie E. Osborne, Bryan L. Swift, Guy A. Baldassarre

Human–Wildlife Interactions

We studied captive-reared mallards (Anas platyrhynchos; CRMs) released on eastern Long Island, New York, in 2006 to 2007 and 2007 to 2008 to determine: (1) survival rates of CRMs; (2) contribution to hunter harvest; (3) local movements; and (4) pair status, reproductive behavior, and production of CRMs. We banded and released 100 CRMs in November 2006 of which 20 were radio-marked. In November 2007, we banded and released 299 CRMs of which 60 were radio-marked. We used Program MARK to determine weekly survival estimates (0.53 to 1.00) up to 24 weeks after release; cumulative survival from November to …

Estimating Annual Vertebrate Mortality On Roads At Saguaro National Park, Arizona, Kenneth Gerow, Natasha C. Kline, Don E. Swann, Marin Pokorny

Human–Wildlife Interactions

Road-killed vertebrates are a conspicuous effect of roads on animals, particularly in natural preserves where wildlife is protected. Knowledge of the number of vertebrates killed by vehicles in a national park or other natural area is important for managers, but these numbers are difficult to estimate because such mortality patterns vary greatly in space and time and by taxonomic group. Additionally, animals killed by vehicles may be difficult to observe, particularly during driving surveys, and carcasses may not persist between surveys due to scavenging and other factors. We modified an estimator previously developed for determining bird mortality at wind turbines …

Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, Crissa K. Cooey, Jesse A. Fallon, Michael L. Avery, James T. Anderson, Elizabeth A. Falkenstein, Hillar Klandorf

Human–Wildlife Interactions

There is no reliable method for determining age for most species of long-lived birds. Recent success using the skin chemical pentosidine as a biomarker has shown promise as an aging tool for birds. Pentosidine levels have been determined only from the breast tissue of carcasses, and we sought to refine the procedure with respect to biopsy size and location for safe and effective use on living birds. We compared pentosidine concentrations in 4 skin-size samples (4, 6, 8, and 20-mm diameter biopsies) from the breast of black vulture (Coragyps atratus) carcasses. We also compared pentosidine levels from breast …

Examining Resistance, Accommodation And The Pursuit Of Aspiration In The Indian It‐Bpo Space: Reflections On Two Case Studies, M. N. Ravishankar, Laurie Cohen, Amal El-Sawad

All Works

This article is based on case studies of two organisations: an India-based information technology (IT) services company and a financial services company located in the UK and India. Although they operate in different sectors and have some notable contrasts, both can be seen as typifying aspects of India's new economy. Our article explores the lived experience of working in this economy—a perspective that has been relatively neglected in the extant literature. Drawing on Homi Bhabha's notions of ambivalence and mimicry, and V. S. Naipaul's powerful illustrations of these concepts in his fiction and non-fiction works, we report on how respondents …

Taxes And Death: The Rise And Demise Of An American Law Firm, Milton C. Regan

Georgetown Law Faculty Publications and Other Works

Misconduct by lawyers in law firms is often attributed to pressures from increasing competition for legal services. Modern firms do face fierce competitive pressures. We can gain more subtle insights, however, by focusing on the specific markets in which particular firms operate and the ways in which forms of influence in law firms interact with common patterns of behavior in organizations.

This paper, a chapter in the collection Law Firms, Legal Culture, and Legal Practice, draws on this type ofanalytical framework to provide a case study of the experience of Jenkens & Gilchrist, a national law firm that had …

Disparate Impact, Girardeau A. Spann

Georgetown Law Faculty Publications and Other Works

There has been a lot of talk about post-racialism since the 2008 election of Barack Obama as the first black President of the United States. Some have argued that the Obama election illustrates the evolution of the United States from its unfortunate racist past to a more admirable post-racial present in which the problem of invidious racial discrimination has largely been overcome. Others have argued that the Obama election illustrates only that an extraordinarily gifted, mixed-race, multiple Ivy League graduate, Harvard Law Review President was able to overcome the persistent discriminatory racial practices that continue to disadvantage the bulk of …

The Unity Of Interpretation, Lawrence B. Solum

Georgetown Law Faculty Publications and Other Works

What is interpretation? One can imagine a range of answers to this question. One answer might begin with the observation that the English word “interpretation” is used to refer to a variety of human activities. Translators at the United Nations interpret remarks made in French when they offer an English translation. Literary critics interpret novels when they investigate the deep and sometimes unconscious motivations of the author. Conductors interpret a score when they make decisions about meter, tempo, and dynamic range. Actors interpret a screenplay when they improvise new lines based on their understanding of the characters. Judges interpret statutes …

Narrative, Normativity, And Causation, Lawrence B. Solum

Georgetown Law Faculty Publications and Other Works

This essay examines the relationship between constitutional narratives, causation, and normativity in the context of Barry Friedman’s book, The Will of the People: How Public Opinion Has Influenced the Supreme Court and Shaped the Meaning of the Constitution. In his book, Friedman provides a grand narrative of American constitutional history that emphasizes the role of public opinion in the development of American constitutional law. That narrative involves both implicit and explicit claims about the causal forces that shape constitutional doctrine and about normative constitutional theory. The aim of this essay is to identify those claims, excavate their theoretical assumptions, …

In Praise Of The Guilty Project: A Criminal Defense Lawyer's Growing Anxiety About Innocence Projects, Abbe Smith

Georgetown Law Faculty Publications and Other Works

There is nothing more compelling than a story about an innocent person wrongly convicted and ultimately vindicated. An ordinary citizen is caught up in the criminal justice system through circumstances beyond his or her control, spends many years in prison, and then one day, with the assistance of a dedicated lawyer, is freed.

Often, when DNA is behind a vindication, not only is the innocent person exonerated but the true perpetrator is identified. This is a significant achievement even though it can also lead apologists for the system—even police and prosecutors implicated in the wrongful conviction—to proudly declare that the …

The Closed Rule, Michael Doran

Georgetown Law Faculty Publications and Other Works

The closed rule constitutes a critical component of managerial power in the contemporary House of Representatives and an increasingly important element of the legislative process. Subject to the approval of the full membership, the closed rule allows managers to block all amendments to a measure when bringing that measure to the floor. Despite objections from the minority, both Republicans and Democrats regularly use the closed rule when in the majority, and rank-and-file members ordinarily approve any closed rule put to a floor vote. Once rarely used, the closed rule has become managers’ preferred instrument for controlling the House floor agenda. …

To Be Muslim Or "Muslim-Looking" In America: A Comparative Exploration Of Racial And Religious Prejudice In The 21st Century, Sheryll Cashin

Georgetown Law Faculty Publications and Other Works

This Essay begins with a confession. In taking implicit association tests ("IATs") designed to measure my unconscious attitude toward two particular demographic groups, I discovered that I, an African-American, harbored a "slight automatic preference" for Europeans over blacks and for "other people" over "Arab-Muslims." Both of these results were contrary to my professed or conscious assertions of neutrality. Why would a pro-integration scholar who seeks to promote cross-racial understanding and inclusion exhibit such implicit biases? And why is it that a majority of others who take these tests register similar implicit biases? The point of my confession is to underscore …

Mapping The Issues: Public Health, Law And Ethics, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The field of public health is typically regarded as a positivistic pursuit and, undoubtedly, our understanding of the etiology and response to disease is heavily influenced by scientific inquiry. Public health policies, however, are shaped not only by science but also by ethical values, legal norms, and political oversight. Public Health Law and Ethics: A Reader (expanded and updated 2nd ed., 2010) probes and seeks to illuminate this complex interplay, through a careful selection of government reports, scholarly articles, and court cases together with discussion and analysis of critical problems at the interface of law, ethics, and public health. The …

How Should Colleges And Universities Respond To Peer Sexual Violence On Campus? What The Current Legal Environment Tells Us, Nancy Chi Cantalupo

Georgetown Law Faculty Publications and Other Works

Over the last decade or so, various legal schemes such as the statutes and court or agency enforcement of Title IX and the Clery Act have increasingly recognized that certain institutional responses perpetuate a cycle of nonreporting and violence. This paper draws upon comprehensive legal research conducted on how the law now regulates school responses to campus peer sexual violence to show that schools face much greater liability from failing to protect the rights of campus peer sexual violence survivors than of any other group of students, including alleged assailants. By encouraging their institutions to develop more victim-centered responses to …

Commandeering The People: Why The Individual Health Insurance Mandate Is Unconstitutional, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

The “Patient Protection and Affordable Care Act” includes what is called an “individual responsibility requirement” or mandate that all persons buy health insurance from a private company and a separate “penalty” enforcing this requirement. In this paper, I do not critique the individual mandate on originalist grounds. Instead, I explain why the individual mandate is unconstitutional under the existing doctrine by which the Supreme Court construes the Commerce and Necessary and Proper Clauses and the tax power. There are three principal claims.

First (Part II), since the New Deal, the Supreme Court has developed a doctrine allowing the regulation of …

Attention Must Be Paid: Commercial Speech, User-Generated Ads, And The Challenge Of Regulation, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

This Article examines the dynamics that drive advertisers to push into new formats, and the law’s ability to regulate them. I argue that it will remain possible, and constitutional, to identify advertising and subject it to prohibitions on false and misleading claims, even for ads in unconventional formats. The article also addresses the ways in which regulators were caught off-guard by these new formats. In particular, Section 230 of the Communications Decency Act, which frees online service providers and users from liability for content generated by other users, poses some unanticipated barriers to regulating advertising. Yet despite section 230’s provisions, …
