Irrelevant Features Of A Stimulus Can Either Facilitate Or Disrupt Performance In A Working Memory Task: The Role Of Fluid Intelligence, Bernardo Perfetti, Marcello Tesse, Sara Varanese, Aristide Saggino, Marco Onofrj

Publications and Research

It has been shown that fluid intelligence (gf) is fundamental to overcome interference due to information of a previously encoded item along a task-relevant domain. However, the biasing effect of task-irrelevant dimensions is still unclear as well as its relation with gf. The present study aimed at clarifying these issues. Gf was assessed in 60 healthy subjects. In a different session, the same subjects performed two versions (letter-detection and spatial) of a three-back working memory task with a set of physically identical stimuli (letters) presented at different locations on the screen. In the letter-detection task, volunteers were asked to match …

Censuring The Praise Of Alienation: Interstices Of Ante-Alienation In Things Fall Apart, No Longer At Ease, And Arrow Of God, Kevin Frank

Publications and Research

Interrogating Abiola Irele’s largely unchallenged praise of alienation, this essay is bold and insightful in returning to Chinua Achebe’s African trilogy to examine the subtler, equally dangerous agent of externality: ante-alienation, or social alienation within traditional African culture, which precedes race-based, colonial alienation. This ante-alienation challenges Négritude’s paradisiacal view of Africa and raises questions about Africans always being happiest with themselves within their traditional culture.

Was The Black Death In India And China?, George D. Sussman

Publications and Research

Firsthand accounts of the Black Death in Europe and the Middle East and many subsequent historians have assumed that the pandemic originated in Asia and ravaged China and India before reaching the West. One reason for this conviction among modern historians is that the plague in the nineteenth century originated and did its worst damage in these countries. But a close examination of the sources on the Delhi Sultanate and the Yuan Dynasty provides no evidence of any serious epidemic in fourteenth-century India and no specific evidence of plague among the many troubles that afflicted fourteenth-century China.

Visualizing History: Using Museum Skills To Teach Information Literacy To Undergraduates, Sandra Roff

Publications and Research

Baruch College began an information studies minor that reinforces the principles of information literacy. However, it did not employ the visual to teach information literacy skills. To fill this gap, a new course, using the process of researching and preparing an exhibit script to teach undergraduates information literacy skills, was developed. In this course students have the opportunity to become creative, while at the same time learning the organizational and research skills needed to compose exhibit proposals, write labels and press releases and finally to produce exhibit script.

Defying De-Stalinization: Albania’S 1956, Elidor Mehilli

Publications and Research

Drawing on recently declassified Albanian, Soviet, East German, and Western archival sources, as well as a rich historiography on Nikita Khrushchev's secret speech and the Hungarian revolution of 1956, this article investigates the little-known events of 1956 in Albania. Rejecting de-Stalinization, the Albanian Communist leader Enver Hoxha was able to vindicate his position against Yugoslavia's brand of socialism abroad, fortify his rule at home, and claim more aid from Moscow, Beijing, and the Soviet bloc. This article discusses the Tirana Party Conference of April 1956, treating the Albanian Party of Labor (the Communist party) as an “information society.” The article …

Age-Related Differences In Idiom Production In Adulthood, Peggy S. Conner, Jungmoon Hyun, Barbara O'Connor-Wells, Inge Anema, Mira Goral, Marie-Michelle Monereau-Merry, Daniel Rubino, Raija Kuckuk, Loraine Obler

Publications and Research

To investigate whether idiom production was vulnerable to age-related difficulties, we asked 40 younger (ages 18–30) and 40 older healthy adults (ages 60–85) to produce idiomatic expressions in a story-completion task. Younger adults produced significantly more correct idiom responses (73%) than did older adults (60%). When older adults generated partially correct responses, they were less likely than younger participants to eventually produce the complete target idiom (old: 32%; young: 70%); first-word cues after initial failure to retrieve an idiom resulted in more correct idioms for older (24%) than younger (15%) participants. Correlations between age and idiom correctness were positive for …

Using The Open Systems Perspective To Understand Critical Incidents, Denise D. P. Thompson

Publications and Research

At the end of its Fall 2010 conference, the Academy for Critical Incident Analysis (ACIA) called for the development of frameworks that would aid in the study and analysis of critical incidents. This paper responds to that call. The paper answers the question, “is it possible to construct a framework that is generic enough to encapsulate the essential components observed in all critical incidents?” The paper utilizes the open systems perspective to develop a conceptual framework to help us delineate and understand critical incidents and how they evolve. The paper presents examples to substantiate arguments made about the framework. The …

Methods: We conducted a cross-sectional survey of 800 FSW and 1,250 female VCT clients in Rwanda, which included interviewing and testing for HIV-1/2, HSV-2 and pregnancy, and BED-CEIA and Avidity Index (AI) to identify recent infections among HIV-infected women.

Results: Prevalence of HIV-1, HSV-2, and pregnancy were 24% (95% CI: 21.0–27.0), 59.8% (56.4–63.2), and 7.6% (5.8–9.5) among FSW, and 12.8% (10.9–14.6), 43.2% (40.4–46.0), and 11.4% (9.7–13.3) among VCT clients, respectively. Thirty-five percent of FSW and 25% of VCT clients had never been HIV tested. Per national guidelines, 33% of newly HIV-diagnosed FSW and 36% of VCT clients were already eligible …

Relationships Between Self-Reported Smoking, Household Environmental Tobacco Smoke Exposure And Depressive Symptoms In A Pregnant Minority Population, Sylvia Tan, Lauren P. Courtney, Ayman El-Mohandes, Susan M. Blake, Marie G. Gantz, Jutta Thornberry, M. Nabil El-Khorazaty, David Perry, Michele Kiely

Publications and Research

This study sought to examine relationships between depressive symptoms and prenatal smoking and/or household environmental tobacco smoke exposure (HHETSE) among urban minority women. We analyzed private, audio computer-assisted self interview data from a clinic-based sample of 929 minority pregnant women in Washington, DC. Depressive symptoms were assessed via the Beck Depression Inventory Fast Screen. HH-ETSE, current smoking, and former smoking were assessed via self-report. Depression levels and demographic characteristics were compared: (1) among nonsmokers, for those reporting HH-ETSE versus no HH-ETSE; and (2) among smokers, for those reporting current smoking (in last 7 days) versus former smokers. Measures associated with …

How Does Socioeconomic Development Affect Copd Mortality? An Age-Period-Cohort Analysis From A Recently Transitioned Population In China, Jing Chen, Mary Schooling, Janice Mary Johnston, Anthony Johnson Hedley, Sarah Morag Mcghee

Publications and Research

Background
Chronic obstructive pulmonary disease (COPD) is a leading cause of death, particularly in developing countries. Little is known about the effects of economic development on COPD mortality, although economic development may potentially have positive and negative influences over the life course on COPD. We took advantage of a unique population whose rapid and recent economic development is marked by changes at clearly delineated and identifiable time points, and where few women smoke, to examine the effect of macro-level events on COPD mortality.

Methods
We used Poisson regression to decompose sex-specific COPD mortality rates in Hong Kong from 1981 to …

This dissertation studies the importance of New York City, and the black intellectuals who gathered there, to the civil rights movement of the 1950s and 1960s. Studying key activist-intellectuals from across the ideological spectrum allows for a more complete understanding of the importance of ideas propelling the movement. The dissertation also contributes to the growing literature on the civil rights movement outside of the South.

Prudence And Controversy: The New York Public Library Responds To Post-War Anticommunist Pressures, Stephen Francoeur

Publications and Research

As the New York Public Library entered the post-war era in the late 1940s, its operations fell under the zealous scrutiny of self-styled ‘redhunters’ intent upon rooting out library materials and staffers deemed un-American and politically subversive. The high point of attacks upon the New York Public Library came during the years 1947-1954, a period that witnessed the Soviet atomic bomb, the Berlin airlift, and the Korean War. This article charts the narrow and carefully wrought trail blazed by the library’s leadership during that period. Through a reading of materials in the library archives, we see how political pressures were …

Pirates And Librarians: Big Media, Technology And The Role Of Liberal Education, D. Aram Donabedian, John Carey

Publications and Research

The widespread appearance of computers in libraries during the early 1990s elicited a debate among those who welcomed new technologies and those who perceived such changes as a threat to the traditional role of academic libraries and the values of liberal education. At the same time, increasing consolidation of major media channels—including sources of scholarly communication—has allowed a small number of corporations to control distribution and access to the materials libraries offer, through tools such as licensing fees, copyright restrictions, and digital rights management. In response to these barriers, librarians and educators have embraced open access publishing and Creative Commons …

Shamanic Knowledge: The Challenge To Information Science, Jay H. Bernstein

Publications and Research

Shamanism, a form of healing involving soul travel and trance found in many traditional societies the world over, has been studied by anthropologists and scholars of religious studies. Shamanic traditions are characterized by specialized, restricted, and esoteric knowledge domains that are encoded and communicated through condensed and mystified symbols and reproduced in ceremonies. Shamanic knowledge is acquired through direct experience of the numinous, usually in the process of overcoming personal affliction. Information science so far has been silent on shamanic knowledge. This is understandable given the latter discipline's focus on formal documentary information systems and advanced information technologies. But in …

Slow Dissociation Of A Charged Ligand: Analysis Of The Primary Quinone Qa Site Of Photosynthetic Bacterial Reaction Centers, Jennifer Madeo, Maja Mihajlovic, Themis Lazaridis, M. R. Gunner

Publications and Research

Reaction centers (RCs) are integral membrane proteins that undergo a series of electron transfer reactions during the process of photosynthesis. In the QA site of RCs from Rhodobacter sphaeroides, ubiquinone-10 is reduced, by a single electron transfer, to its semiquinone. The neutral quinone and anionic semiquinone have similar affinities, which is required for correct in situ reaction thermodynamics. A previous study showed that despite similar affinities, anionic quinones associate and dissociate from the QA site at rates ≈104 times slower than neutral quinones indicating that anionic quinones encounter larger binding barriers (Madeo, J.; Gunner, M. R. Modeling binding kinetics at …

Genomic And Karyotypic Variation In Drosophila Parasitoids (Hymenoptera, Cynipoidea, Figitidae), Vladimir E. Gokhman, J. Spencer Johnston, Chiyedza Small, Roma Rajwani, Shawn J. Hanrahan, Shubha Govind

Publications and Research

Abstract Drosophila melanogaster Meigen, 1830 has served as a model insect for over a century. Sequencing of the 11 additional Drosophila Fallen, 1823 species marks substantial progress in comparative genomics of this genus. By comparison, practically nothing is known about the genome size or genome sequences of parasitic wasps of Drosophila. Here, we present the first comparative analysis of genome size and karyotype structures of Drosophila parasitoids of the Leptopilina Förster, 1869 and Ganaspis Förster, 1869 species. The gametic genome size of Ganaspis xanthopoda (Ashmead, 1896) is larger than those of the three Leptopilina species studied. The genome sizes of …

Insightful Problem Solving In An Asian Elephant, Preston Foerder, Marie Galloway, Tony Barthel, Donald E. Moore Iii, Diana Reiss

Publications and Research

The ‘‘aha’’ moment or the sudden arrival of the solution to a problem is a common human experience. Spontaneous problem solving without evident trial and error behavior in humans and other animals has been referred to as insight. Surprisingly, elephants, thought to be highly intelligent, have failed to exhibit insightful problem solving in previous cognitive studies. We tested whether three Asian elephants (Elephas maximus) would use sticks or other objects to obtain food items placed out-of-reach and overhead. Without prior trial and error behavior, a 7-year-old male Asian elephant showed spontaneous problem solving by moving a large plastic cube, on …

Age-Related Deficits In Spatial Memory And Hippocampal Spines In Virgin, Female Fischer 344 Rats, Victoria N. Luine, Maureen E. Wallace, Maya Frankfurt

Publications and Research

Effects of aging on memory and brain morphology were examined in aged, 21-month-old, and young, 4-month-old, Fischer 344 female rats. Spatial memory was assessed using the object placement task, and dendritic spine density was determined on pyramidal neurons in the hippocampus following Golgi impregnation. Consistent with previous studies, aged females showed poorer object placement performance than young subjects. Young subjects significantly discriminated the location of objects with a 1.5-hour intertrial delay while aged subjects did not. Spine density of basal dendrites on CA1 pyramidal cells was 16% lower in the aged subjects as compared to the young subjects. No differences …

The Accuracy Of The Electrocardiogram During Exercise Stress Test Based On Heart Size, Jason C. Siegler, Shafiq Rehman, Geetha P. Bhumireddy, Raushan Abdula, Igor Klem, Sorin J. Brener, Leonard Lee, Christopher C. Dunbar, Barry Saul, Terrence J. Sacchi, John F. Heitner

Publications and Research

Background Multiple studies have shown that the exercise electrocardiogram (ECG) is less accurate for predicting ischemia, especially in women, and there is additional evidence to suggest that heart size may affect its diagnostic accuracy. Hypothesis The purpose of this investigation was to assess the diagnostic accuracy of the exercise ECG based on heart size. Methods We evaluated 1,011 consecutive patients who were referred for an exercise nuclear stress test. Patients were divided into two groups: small heart size defined as left ventricular end diastolic volume (LVEDV) <65 mL (Group A) and normal heart size defined as LVEDV ≥65 mL (Group B) and associations between ECG outcome (false positive vs. no false positive) and heart size (small vs. normal) were analyzed using the Chi square test for independence, with a Yates continuity correction. LVEDV calculations were performed via a computer-processing algorithm. SPECT myocardial perfusion imaging was used as the gold standard for the presence of coronary artery disease (CAD). Results Small heart size was found in 142 patients, 123 female and 19 male patients. There was a significant association between ECG outcome and heart size (χ2 = 4.7, p = 0.03), where smaller hearts were associated with a significantly greater number of false positives. Conclusions This study suggests a possible explanation for the poor diagnostic accuracy of exercise stress testing, especially in women, as the overwhelming majority of patients with small heart size were women.

The evolution of the amniotic egg was one of the great evolutionary innovations in the history of life, freeing vertebrates from an obligatory connection to water and thus permitting the conquest of terrestrial environments1. Among amniotes, genome sequences are available for mammals2 and birds3–5, but not for non-avian reptiles. Here we report the genome sequence of the North American green anole lizard, Anolis carolinensis. We find that A. carolinensis microchromosomes are highly syntenic with chicken microchromosomes, yet do not exhibit the high GC and low repeat content that are characteristic of avian microchromosomes3. Also, A. carolinensis mobile elements are very …

Intraventricular hemorrhage (IVH) results in neural cell death and white matter injury in premature infants. No therapeutic strategy is currently available against this disorder. Bone morphogenetic protein (BMP) signaling suppresses oligodendrocyte development through basic-helix-loop-helix (bHLH) transcription factors and promotes astrocytosis. Therefore, we hypothesized that IVH in premature newborns initiates degeneration and maturation arrest of oligodendrocyte lineage and that BMP inhibition alleviates hypomyelination, gliosis, and motor impairment in the survivors of IVH. To test the hypotheses, a rabbit model of IVH was used in which premature rabbit pups (E29) are treated with intraperitoneal glycerol at 2 hours of age to induce …

Graded Index And Randomly Oriented Core-Shell Silicon Nanowires With Broadband And Wide Angle Antireflection, P. Pignalosa, H. Lee, L. Qiao, M. Tseng, Y. Yi

Publications and Research

Antireflection with broadband and wide angle properties is important for a wide range of applications on photovoltaic cells and display. The SiOx shell layer provides a natural antireflection from air to the Si core absorption layer. In this work, we have demonstrated the random core-shell silicon nanowires with both broadband (from 400nm to 900nm) and wide angle (from normal incidence to 60o) antireflection characteristics within AM1.5 solar spectrum. The graded index structure from the randomly oriented core-shell (Air/SiOx/Si) nanowires may provide a potential avenue to realize a broadband and wide angle antireflection layer

Effectiveness Of A Combined Home Visiting And Group Intervention For Low Income African American Mothers: The Pride In Parenting Program, Kathy S. Katz, Marian H. Jarrett, Ayman El-Mohandes, Susan Schneider, Doris Mcneely-Johnson, Michele Kiely

Publications and Research

Intervention strategies are needed to improve maternal and infant outcomes in minority populations living in poverty. Home visiting by nurses has improved outcomes for mothers and young children, but use of professional staff makes these programs expensive. Pride in Parenting was a randomized controlled trial of paraprofessional home visitation to provide health and developmental intervention for high-risk African American mothers in Washington, DC. This study proposed to test whether paraprofessional visitors drawn from the community could effectively influence health and mothers; parenting behaviors and attitudes. African American mothers with inadequate prenatal care were recruited at delivery and randomized to intervention …
