Smith, Craig L. Katz, Vansh Sharma, Dennis S. Charney, Robin Herbert, Jacqueline Moline, Benjamin J. Luft, Steven Markowitz, Iris Udasin, Denise Harrison, Sherry Baron, Philip J. Landrigan, Stephen M. Levin, Steven Southwick

Publications and Research

Background The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a large cohort of WTC rescue, recovery, and cleanup workers. We previously documented extensive pulmonary dysfunction in this cohort related to toxic environmental exposures. Objectives Our objective in this study was to describe mental health outcomes, social function impairment, and psychiatric comorbidity in the WTC worker cohort, as well as …

Rejuvenate Pointcut: A Tool For Pointcut Expression Recovery In Evolving Aspect-Oriented Software, Raffi Khatchadourian, Awais Rashid

Publications and Research

Aspect-oriented programming (AOP) strives to localize the scattered and tangled implementations of crosscutting concerns (CCCs) by allowing developers to declare that certain actions (advice) should be taken at specific points (join points) during the execution of software where a CCC (an aspect) is applicable. However, it is non-trivial to construct optimal pointcut expressions (a collection of join points) that capture the true intentions of the programmer and, upon evolution, maintain these intentions. We demonstrate an AspectJ source-level inferencing tool called rejuvenate pointcut which helps developers maintain pointcut expressions over the lifetime of a software product. A key insight into the …

An Integrated Intervention In Pregnant African Americans Reduces Postpartum Risk: A Randomized Trial, Ayman El-Mohandes, Michele Kiely, Jill G. Joseph, Siva Subramanian, Allan A. Johnson, Susn M. Blake, Marie G. Gantz, M. Nabil El-Khorazaty

Publications and Research

Objective—To evaluate the efficacy of an integrated multiple risk intervention delivered mainly during pregnancy, in reducing such risks (smoking, environmental tobacco smoke exposure, depression and intimate partner violence) postpartum.

Design—Data from this randomized controlled trial were collected prenatally and on average 10 weeks postpartum in six prenatal care sites in the District of Columbia. African Americans were screened, recruited and randomly assigned to the behavioral intervention or usual care. Clinic-based, individually tailored counseling was delivered to intervention women. The outcome measures were number of reisks reported postpartum and reduction of these risks between baseline and postpartum.

The Contribution Of Advective Fluxes To Net Ecosystem Exchange In A High-Elevation, Subalpine Forest, Chuixiang Yi, Dean E. Anderson, Andrew A. Turnipseed, Sean P. Burns, Jed P. Sparks, David I. Stannard, Russell K. Monson

Publications and Research

The eddy covariance technique, which is used in the determination of net ecosystem CO₂ exchange (NEE), is subject to significant errors when advection that carries CO₂ in the mean flow is ignored. We measured horizontal and vertical advective CO₂ fluxes at the Niwot Ridge AmeriFlux site (Colorado, USA) using a measurement approach consisting of multiple towers. We observed relatively high rates of both horizontal (F_hadv) and vertical (F_vadv) advective fluxes at low surface friction velocities (u_*) which were associated with downslope katabatic flows. We observed that F_hadv was confined to …

Donning The Cloak: Safavid Figural Silks And The Display Of Identity, Nazanin Hedayat Munroe

Publications and Research

Introduction

In a red world bathed in shimmering gold light, a man sits with his head in his hand as wild beasts encircle him. He is emaciated, has unkempt hair, and wears only a waistcloth—but he has a dreamy smile on his face. Nearby, a camel bears a palanquin carrying a stately woman, her head tipped to one side, arm outstretched from the window of her traveling abode toward her lover. Beneath her, the signature “Work of Ghiyath” is woven in Kufic script inside an eightpointed star on the palanquin (Fig. 1).

Dynamic Surface Activity By Folding And Unfolding An Amphiphilic Α-Helix, Vikas Jain, Angela Jimenez, Charles Maldarelli, Raymond S. Tu

Publications and Research

We describe a rationally designed peptide with tunable surface activity, where the dynamics of surface activity are an outcome of helical folding. Our rationally designed model peptide is surface-active only as an α-helix. We apply circular dichroism to show that the folded population can be controlled with changes in electrolyte concentration, and we apply pendant bubble tensiometry to explore dynamic surfactant activity. This study shows a peptide that responds to environmental stimuli with dynamic folding and surface activity. Extending this concept to selective binding peptides will lead to new tools, where dynamic surface activity is coupled to targeted binding.

Claims Of Potential Expansion Throughout The U.S. By Invasive Python Species Are Contradicted By Ecological Niche Models, R. Alexander Pyron, Frank T. Burbrink, Timothy J. Guiher

Publications and Research

Background Recent reports from the United States Geological Survey (USGS) suggested that invasive Burmese pythons in the Everglades may quickly spread into many parts of the U.S. due to putative climatic suitability. Additionally, projected trends of global warming were predicted to significantly increase suitable habitat and promote range expansion by these snakes. However, the ecological limitations of the Burmese python are not known and the possible effects of global warming on the potential expansion of the species are also unclear. Methodology/Principal Findings Here we show that a predicted continental expansion is unlikely based on the ecology of the organism and …

Riordan, Wenjun Li, Santiago Juarez, Andrea M. Crabb, Thomas J. Lukas, Pan Du, Simon M. Lin, Alexandria Wise, Olga A. Agapova, Ping Yang, Charles C. Gu, M. Rosario Hernandez

Publications and Research

Purpose To determine whether optic nerve head (ONH) astrocytes, a key cellular component of glaucomatous neuropathy, exhibit differential gene expression in primary cultures of astrocytes from normal African American (AA) donors compared to astrocytes from normal Caucasian American (CA) donors. Methods We used oligonucleotide Affymetrix microarray (HG U133A & HG U133A 2.0 chips) to compare gene expression levels in cultured ONH astrocytes from twelve CA and twelve AA normal age matched donor eyes. Chips were normalized with Robust Microarray Analysis (RMA) in R using Bioconductor. Significant differential gene expression levels were detected using mixed effects modeling and Statistical Analysis of …

New Breast Milk In Old Bottles, Barbara Katz Rothman

Publications and Research

This paper identifies how the different ideologies of patriarchy, technology, capitalism, race and feminism shape how we see breastfeeding and the breastfeeding mother with child. Ultimately, while we can make good strong arguments for breastfeeding from the perspective of health, of outcome, of good scientific data, we need to appreciate that they are only rationalizations for a shared belief that the image of the breastfeeding woman with baby represents something precious and valuable. So while it may be important to make arguments that draw on what is valued in society, we need to think hard about what it is that …

Pointcut Rejuvenation: Recovering Pointcut Expressions In Evolving Aspect-Oriented Software, Raffi Khatchadourian, Phil Greenwood, Awais Rashid, Guoqing Harry Xu

Publications and Research

Pointcut fragility is a well-documented problem in Aspect-Oriented Programming; changes to the base-code can lead to join points incorrectly falling in or out of the scope of pointcuts. In this paper, we present an automated approach which limits fragility problems by providing mechanical assistance in pointcut maintenance. The approach is based on harnessing arbitrarily deep structural commonalities between program elements corresponding to join points selected by a pointcut. The extracted patterns are then applied to later versions to offer suggestions of new join points that may require inclusion. To illustrate that the motivation behind our proposal is well-founded, we first …

Laurate Biosensors Image Brain Neurotransmitters In Vivo: Can An Antihypertensive Medication Alter Psychostimulant Behavior?, Patricia A. Broderick, Helen Ho, Karyn Wat, Vivek Murthy

Publications and Research

Neuromolecular Imaging (NMI) with novel biosensors enables the selective detection of neurotransmitters in vivo within seconds, on line and in real time. Biosensors remain in place for continuing studies over a period of months. This biotechnological advance is based on conventional electrochemistry; the biosensors detect neurotransmitters by electron transfer. Simply stated, biosensors adsorb electrons from each neurotransmitter at specific oxidation potentials; the current derived from electron transfer is proportional to neurotransmitter concentration. Selective electron transfer properties of these biosensors permit the imaging of neurotransmitters, metabolites and precursors. The novel BRODERICK PROBE® biosensors we have developed, differ in formulation and detection …

Cities Of Consumption: The Impact Of Corporate Practices On The Health Of Urban Populations, Nicholas Freudenberg, Sandro Galea

Publications and Research

The increasing concentration of the world's population in cities and the growing accumulation of political and economic power by corporations create new threats to health and opportunities for improving global health. By considering the intersection of these two fundamental social determinants of well-being, we elucidate some of the mechanisms by which they influence the health of urban populations. After reviewing the changing historical impact of corporations on cities, we focus on the growth of consumption as a leading cause of mortality and morbidity and describe how the food, tobacco, automobile, and other industries promote unhealthy behaviors and lifestyles in urban …

Rousseau, The Anticosmopolitan?, Helena Rosenblatt

Publications and Research

Rousseau's repeated criticisms of the Enlightenment's ideal of cosmopolitanism has led to his thought being characterized as 'anticosmopolitan'. His work abounds in denunciations of the ideals of equality of treatment and universal rights supported by his contemporaries. Moreover, his liking of solitude, introspection and socialization in small circles and his preference for patriotism over equity among all men seem to set him up as the counterpoint of the universalism his contemporaries defended. However, a deeper insight into the work of the author of The Reveries of the Solitary Walker shows that, far from being incompatible with true cosmopolitanism, the moral …

Sexual Violence As The Language Of Border Control: Where French Feminist And Anti‐Immigrant Rhetoric Meet, Miriam Ticktin

Publications and Research

When I first arrived in the Paris region in 1999 to do research on the struggle by undocumented immigrants (les sans papiers) for basic human rights, discussions of violence against women were remarkably absent from the public arena. Nongovernmental organizations and researchers had begun to broach the topic, but with little public visibility. However, this changed in late 2000, with a media explosion on the issue of les tournantes, or the gang rapes committed in the banlieues of Paris. Such tournantes involve boys “taking turns” with their friends’ girlfriends, both parties usually being of Maghrebian or North …

Purloined Voices: Edgar Allan Poe Reading Samuel Taylor Coleridge, Alexander M. Schlutz

Publications and Research

This essay unfolds the complex intertextual relationship between the work of Samuel Taylor Coleridge and that of Edgar Allan Poe. References to and extended borrowings from Coleridge’s poetry and philosophical texts mark Poe’s œuvre throughout, but – as is only fitting for borrowings from the great borrower Coleridge – they are never anything as simple as plagiarisms or acts of intellectual theft. As this piece demonstrates through readings of Poe’s early poetological text “Letter to B–,” the Dupin story “The Purloined Letter,” and the late tour-de-force prose-poem Eureka, tracing the recurrence of Coleridgean poetry and prose in the work …

Las Cuestiones Sicilianas De Ibn Sab‘Īn: El Texto, Sus Fuentes Y Su Contexto Histórico, Anna Ayşe Akasoy

Publications and Research

The Sicilian Questions are the earliest pre-served text of the philosopher and Sufi Ibn Sab‘īn of Murcia (c. 614/1217-668/1270). Even though the prologue of the text claims that it is a response to questions sent by Frederick II to the Arab world, it seems more likely that it was an introductory manual for Arab students of philosophy, dealing with four specific and controversial problems as away of presenting general concepts of Aristotelian philosophy. This article analyses the structure and way of argumentation in the Sicilian Questions. Particular attention is being paid to the relationship between mysticism and philosophy and …

Articulating Identity: Refining Postcolonial And Whiteness Perspectives On Race Within Communication Studies, Gordon Alley-Young

Publications and Research

This paper juxtaposes postcolonial and whiteness scholarship to identify gaps and clarify influences on critical race scholarship within communication studies. This paper considers the multiplicity of each perspective and identifies the focus on race and the body as communicative texts as a linkage that unites the three perspectives. How each perspective informs a communicative understanding of race is explored through the constructs of Cartesian dualism, performance, and the gaze. The paper concludes with suggestions for future directions for interrogating race within the communication discipline, including a consideration of how white privilege is extended to and assumed by individuals who are …

Demonstrating Cerebral Vascular Networks: A Comparison Of Methods For The Teaching Laboratory, Raddy L. Ramos, Phoebe T. Smith, Susan D. Croll, Joshua C. Brumberg

Publications and Research

One challenge of neuroscience educators is to make accessible to students as many aspects of brain structure and function as possible. The anatomy and function of the cerebrovasculature is among many topics of neuroscience that are underrepresented in undergraduate neuroscience education. Recognizing this deficit, we evaluated methods to produce archival tissue specimens of the cerebrovasculature and the “neurovascular unit” for instruction and demonstration in the teaching lab. An additional goal of this project was to identify the costs of each method as well as to determine which method(s) could be adapted into lab exercises, where students participate in the tissue …

Host Proteins Interacting With The Moloney Murine Leukemia Virus Integrase: Multiple Transcriptional Regulators And Chromatin Binding Factors, Barbara Studamire, Stephen P. Goff

Publications and Research

Background A critical step for retroviral replication is the stable integration of the provirus into the genome of its host. The viral integrase protein is key in this essential step of the retroviral life cycle. Although the basic mechanism of integration by mammalian retroviruses has been well characterized, the factors determining how viral integration events are targeted to particular regions of the genome or to regions of a particular DNA structure remain poorly defined. Significant questions remain regarding the influence of host proteins on the selection of target sites, on the repair of integration intermediates, and on the efficiency of …
