Pregnancy Intentions And Happiness Among Pregnant Black Women At High Risk For Adverse Infant Health Outcomes, Susan M. Blake, Michele Kiely, Charlotte C. Gard, Ayman El-Mohandes, M. Nabil El-Khorazaty, Nih-Dc Initiative

Publications and Research

CONTEXT:Unintended pregnancy is associated with risk behaviors and increased morbidity or mortality for mothers and infants, but a woman's feelings about pregnancy may be more predictive of risk and health outcomes than her intentions.

METHODS: A sample of 1,044 black women who were at increased risk were enrolled at prenatal care clinics in the District of Columbia in 2001-2003. Bivariate and multivariate analyses assessed associations between pregnancy intentions or level of happiness about being pregnant and multiple psychosocial and behavioral risk factors, and identified correlates of happiness to be pregnant.

RESULTS: Pregnancy intentions and happiness were strongly associated, but …

Tempo-Spatial Patterns Of Land Use Changes And Urban Development In Globalizing China: A Study Of Beijing, Yichun Xie, Chuanglin Fang, George C.S. Lin, Hongmian Gong, Biao Qiao

Publications and Research

This study examines the temporal and spatial changes in land use as a consequence of rapid urban development in the city of Beijing. Using a combination of techniques of remote sensing and GIS, the study identifies a substantial loss of plain dryland and a phenomenal expansion of urban construction land over the recent decade. Geographically, there is a clear shifting of urban construction land from the inner city to the outskirts as a consequence of suburbanization. The outward expansion of the ring-road system is found to be one of the most important driving forces explaining the temporal and spatial pattern …

Cell Death In Health And Disease, Richard A. Lockshin, Zahra Zakeri

Publications and Research

Cell death is clearly an important factor in development, homeostasis, pathology and in aging, but medical efforts based on controlling cell death have not become major aspects of medicine. There are several reasons why hopes have been slow to be fulfilled, and they present indications for new directions in research. Most effort has focused on the machinery of cell death, or the proximate effectors of apoptosis and their closely associated and interacting proteins. But cells have many options other than apoptosis. These include autophagy, necrosis, atrophy and stepwise or other alternate means of self-disassembly. The response of a cell to …

Deafness Mutation Mining Using Regular Expression Based Pattern Matching, Christopher M. Frenz

Publications and Research

Background: While keyword based queries of databases such as Pubmed are frequently of great utility, the ability to use regular expressions in place of a keyword can often improve the results output by such databases. Regular expressions can allow for the identification of element types that cannot be readily specified by a single keyword and can allow for different words with similar character sequences to be distinguished.

Results: A Perl based utility was developed to allow the use of regular expressions in Pubmed searches, thereby improving the accuracy of the searches.

Conclusion: This utility was then utilized to create a …

Novel In Silico Method For Teaching Cytoarchitecture, Cellular Diversity, And Gene Expression In The Mammalian Brain, Raddy L. Ramos, Phoebe T. Smith, Joshua C. Brumberg

Publications and Research

Neuroanatomy can be a challenging topic for undergraduates, making the development of new methods of instruction an important goal of neuroscience educators. In the present report we describe the utility and versatility of the Allen Brain Atlas as a novel tool for instruction of several important anatomical principles of the mammalian central nervous system. Using this digital database, we detail how instructors of laboratory or lecture-based courses can demonstrate cytoarchitecture, cellular diversity, and gene expression profiles of the brain.

Northeast Under/Graduate Research Organization For Neuroscience (Neuron): Our Third New York City Meeting, Sharon Ramos Goyette, Kassandra L. Edinger, Vicki Luine, Jason Young, Cheryl A. Frye

Publications and Research

The NorthEast Under/graduate Research Organization for Neuroscience (N.E.U.R.O.N.) promotes preparation, education, and undergraduate research in Neuroscience. The N.E.U.R.O.N. Conference was initially held at undergraduate institutions primarily in New England. Then, for the previous two years, to broaden its impact and increase diversity, the meeting moved to Hunter College, CUNY, New York. This year represents the first year in which two N.E.U.R.O.N. meetings were held, one in Boston and one in New York City. The following is a report of the New York City meeting which was held at Hunter College on April 28, 2007. Eminent Neuroscientist, Dr. Carol Sue Carter, …

Reframing School Dropout As A Public Health Issue, Nicholas Freudenberg, Jessica Ruglis

Publications and Research

Good education predicts good health, and disparities in health and in educational achievement are closely linked. Despite these connections, public health professionals rarely make reducing the number of students who drop out of school a priority, although nearly one-third of all students in the United States and half of black, Latino, and American Indian students do not graduate from high school on time. In this article, we summarize knowledge on the health benefits of high school graduation and discuss the pathways by which graduating from high school contributes to good health. We examine strategies for reducing school dropout rates with …

Cracking Silent Codes: Critical Race Theory And Education Organizing, Celina Su

Publications and Research

Critical race theory (CRT) has moved beyond legal scholarship to critique the ways in which “colorblind” laws and policies perpetuate existing racial inequalities in education policy. While criticisms of CRT have focused on the pessimism and lack of remedies presented, CRT scholars have begun to address issues of praxis. Specifically, communities of color must challenge the dominant narratives of mainstream institutions with alternative visions of pedagogy and school reform, and community organizing plays an important role in helping communities of color to articulate these alternative counter-narratives. Yet, many in education organizing disagree with CRT's critique of colorblindness. Drawing on five …

Perigenual Anterior Cingulate Morphology Covaries With Perceived Social Standing, Peter J. Gianaros, Jeffrey A. Horenstein, Sheldon Cohen, Karen A. Matthews, Sarah M. Brown, Janine D. Flory, Hugo D. Critchley, Stephen B. Manuck, Ahmad R. Hariri

Publications and Research

Low socioeconomic status (SES) increases the risk for developing psychiatric and chronic medical disorders. A stress-related pathway by which low SES may affect mental and physical health is through the perception of holding a low social standing, termed low subjective social status. This proposal implicates overlapping brain regions mediating stress reactivity and socioemotional behaviors as neuroanatomical substrates that could plausibly link subjective social status to health-related outcomes. In a test of this proposal, we used a computational structural neuroimaging method (voxel-based morphometry) in a healthy community sample to examine the relationships between reports of subjective social status and regional gray …

Nectin-Like Proteins Mediate Axon–Schwann Cell Interactions Along The Internode And Are Essential For Myelination, Patrice Maurel, Steven Einheber, Jolanta Galinska, Pratik Thaker, Isabel Lam, Marina B. Rubin, Steven S. Scherer, Yoshinuri Murakami, David H. Gutmann, James L. Salzer

Publications and Research

Axon–glial interactions are critical for the induction of myelination and the domain organization of myelinated fibers. Although molecular complexes that mediate these interactions in the nodal region are known, their counterparts along the internode are poorly defined. We report that neurons and Schwann cells express distinct sets of nectin-like (Necl) proteins: axons highly express Necl-1 and -2, whereas Schwann cells express Necl-4 and lower amounts of Necl-2. These proteins are strikingly localized to the internode, where Necl-1 and -2 on the axon are directly apposed by Necl-4 on the Schwann cell; all three proteins are also enriched at Schmidt-Lanterman incisures. …

A Rotating Panel Survey To Assess Quality Of Hunter College Education, Jennifer Sousa Brennan, William (Bill) H. Williams

Publications and Research

A rotating sample design is proposed to most accurately measure the perceived quality of a Hunter College education. A representative sample of Hunter College students will belong to one of six rotating panels. Students will be contacted during four rotation periods and report their assessment of the two most recent months. It is advantageous to use a rotating panel design as opposed to a fixed panel design in order to guard against the negative effects of a deteriorating response rate. Stratified sampling will help to ensure representation across major departments and academic year of study. Methods for sampling procedures, stratification, …

Human Mst But Not Mt Responds To Tactile Stimulation, Michael S. Beauchamp, Nafi E. Yasar, Neel Kishan, Tony Ro

Publications and Research

Previous reports of tactile responses in human visual area MT/V5 have used complex stimuli, such as a brush stroking the arm. These complex moving stimuli are likely to induce imagery of visual motion, which is known to be a powerful activator of MT. The area described as “MT” in previous reports consists of at least two distinct cortical areas, MT and MST. Using functional magnetic resonance imaging, we separately localized human MT and MST and measured their response to vibrotactile stimuli unlikely to induce imagery of visual motion. Strong vibrotactile responses were observed in MST but not in MT. Vibrotactile …

Msbayes: Pipeline For Testing Comparative Phylogeographic Histories Using Hierarchical Approximate Bayesian Computation, Michael J. Hickerson, Eli Stahl, Naoki Takebayashi

Publications and Research

Background Although testing for simultaneous divergence (vicariance) across different population-pairs that span the same barrier to gene flow is of central importance to evolutionary biology, researchers often equate the gene tree and population/species tree thereby ignoring stochastic coalescent variance in their conclusions of temporal incongruence. In contrast to other available phylogeographic software packages, msBayes is the only one that analyses data from multiple species/population pairs under a hierarchical model. Results msBayes employs approximate Bayesian computation (ABC) under a hierarchical coalescent model to test for simultaneous divergence (TSD) in multiple co-distributed population-pairs. Simultaneous isolation is tested by estimating three hyper-parameters that …

Comparative Mitochondrial Genomics Of Snakes: Extraordinary Substitution Rate Dynamics And Functionality Of The Duplicate Control Region, Zhi J. Jiang, Todd A. Castoe, Christopher C. Austin, Frank T. Burbrink, Matthew D. Herron, Jimmy A. Mcguire, Christopher L. Parkinson, David D. Pollock

Publications and Research

Background The mitochondrial genomes of snakes are characterized by an overall evolutionary rate that appears to be one of the most accelerated among vertebrates. They also possess other unusual features, including short tRNAs and other genes, and a duplicated control region that has been stably maintained since it originated more than 70 million years ago. Here, we provide a detailed analysis of evolutionary dynamics in snake mitochondrial genomes to better understand the basis of these extreme characteristics, and to explore the relationship between mitochondrial genome molecular evolution, genome architecture, and molecular function. We sequenced complete mitochondrial genomes from Slowinski's corn …

Violence, Vision, And Voice: A Journey From Liminal To Transgressive Spaces, Stephanie Urso Spina

Publications and Research

This paper was inspired by the author’s experiences teaching a required class about feminism to affluent, predominantly female undergraduates who vociferously considered it outdated and irrelevant to their lives until they realized, in painfully personal ways, that this was the dominant discourse speaking, not their own voices. Inspired by these women, and in the hope of further displacing the hegemonically imposed code of silence, this paper breaks the author’s tacit complicity with these societal forces of repression. Written on a bus from Boston to New York, the author weaves her narrative with a description of that trip and its passengers, …

Utility And Versatility Of Extracellular Recordings From The Cockroach For Neurophysiological Instruction And Demonstration, Raddy L. Ramos, Andrew Moiseff, Joshua C. Brumberg

Publications and Research

The principles of neurophysiology continue to be challenging topics to teach in the context of undergraduate neuroscience education. Laboratory classes containing neurophysiological demonstrations and exercises are, therefore, an important and necessary complement for covering those subjects taught in lecture-based courses. We developed a number of simple yet very instructive exercises, described below, which make use of extracellular recordings from different sensory systems of the cockroach (Periplanta americana). The compendium we developed provides students with hands-on demonstrations of several commonly taught topics of neurophysiology including sensory coding by neural activity.

Digg.Com And Socially-Driven Authority, Steven Ovadia

Publications and Research

For years, librarians have been able to distill the notion of authority, in its purest form, to two simple questions: “Who said it?” and “Under whose auspices?” The answer to either, or preferably both, of these questions could tell a researcher whether to rely on the information retrieved. Today, however, in the world of online information, the notion of authority is shifting and librarians working in an instructional capacity must understand the shift and determine ways to help students cope with the changes. Searching in today’s socially-driven information era requires a different skill set for researchers looking for authoritative information. …

Research Authority In The Age Of Google: Equilibrium Sought, Mariana Regalado

Publications and Research

The article examines the major shift in the relationship of students, instructors and librarians to information. It is argued that this shift is due to some fundamental changes to authority in the relationship in terms of Web publication, access to content and technical know-how. In addition, it also discusses the impact of the introduction of the Google search engine.

Editorial: Shape Shifters: Librarians Evolve Yet Again In The Age Of Google, Mariana Regalado, Jill Cirasella

Publications and Research

Like all organisms and organizations, librarians and libraries evolve by adapting to changes and pressures in their environments. From scroll to codex to online text: every upgrade in technology is matched by an adaptation in librarianship. Nevertheless, despite centuries of evolution, the activities of librarians and the mission of libraries have remained essentially constant and are still recognizable. The pace of change in libraries has been especially rapid since the introduction of computers, and an important recent change is the advent of the “age of Google.” Heralded by the arrival in 1998 of the Google search engine, with its clean …

New York Placenames In Film Titles, Jay H. Bernstein

Publications and Research

From 1914 to 2006, 396 feature films with titles containing New York place names were released. This pattern emerged during the silent era, peaked from the late 1920s to the early 1940s, and then dropped off steadily before rebounding in the 1970s. This article discusses the cinematic representation of cities and urban life in the movies and the special place of New York as an “imagined city” and a cultural icon. New York’s associations in the popular imagination help explain the frequent occurrence of themes of negativity, violence, nightlife, and grandiosity (royalty or divinity) in these titles. The use of …

You And Me And Google Makes Three: Welcoming Google Into The Reference Interview, Jill Cirasella

Publications and Research

Library patrons often approach the reference desk with indirect, incomplete, or misleading questions, known as "ill-formed" questions. Transforming ill-formed questions into well-formed ones is a crucial part of the reference interview, and Google can be an active participant in that process. This paper discusses how Google can help librarians and patrons deal with incomplete citations, incorrect citations, incorrect spellings, tip-of-the-tongue questions, and forgotten searches.

A Reduction Algorithm For Computing The Hybridization Number Of Two Trees, Magnus Bordewich, Simone Linz, Katherine St. John, Charles Semple

Publications and Research

Hybridization is an important evolutionary process for many groups of species. Thus, conflicting signals in a data set may not be the result of sampling or modeling errors, but due to the fact that hybridization has played a significant role in the evolutionary history of the species under consideration. Assuming that the initial set of gene trees is correct, a basic problem for biologists is to compute this minimum number of hybridization events to explain this set. In this paper, we describe a new reduction-based algorithm for computing the minimum number, when the initial data set consists of two trees. …

Low-Income Minority Mothers’ Reports Of Infant Health Care Utilisation Compared With Medical Records, Kennan D. Murray, Ayman El-Mohandes, M. Nabil El-Khorazaty, Michele Kiely

Publications and Research

This study aimed to investigate mothers’ reporting of the nature, location, frequency and content of health care visits for their infants, as compared with data abstracted from the infants’ medical records. It was part of a community-based parenting intervention designed to improve preventive health care utilisation among minority mothers in Washington, DC. Mothers 18 years old with newborn infants and with poor or no prenatal care were enrolled in the study. A total of 160 mother–infant dyads completed the 12-month study. Mothers were interviewed when the infants were 4, 8 and 12 months old, and were asked to recall infant …

Sensory Deprivation Alters Aggrecan And Perineuronal Net Expression In The Mouse Barrel Cortex, Paulette A. Mccrae, Mary M. Rocco, Gail Kelly, Joshua C. Brumberg, Russell T. Matthews

Publications and Research

An important role for the neural extracellular matrix in modulating cortical activity-dependent synaptic plasticity has been established by a number of recent studies. However, identification of the critical molecular components of the neural matrix that mediate these processes is far from complete. Of particular interest is the perineuronal net (PN), an extracellular matrix component found surrounding the cell body and proximal neurites of a subset of neurons. Because of the apposition of thePNto synapses and expression of this structure coincident with the close of the critical period, it has been hypothesized that nets could play uniquely important roles in synapse …
