Responding To Secondary Traumatic Stress: A Pilot Study Of Torture Treatment Programs In The United States, Adeyinka M. Akinsulure-Smith, Eva Keatley, Andrew Rasmussen

Publications and Research

Providers who care for torture survivors may be at risk for secondary traumatic stress, yet there has been little documentation of the effects of repeated exposure to traumatic issues on their emotional health or exploration of the support systems and resources available to address their emotional needs. This study assessed the secondary stress experiences of service providers (N = 43) within the National Consortium of Torture Treatment Programs in the United States and examined the supports offered by their organizations. The study found a significant correlation between rates of anxiety and depression among providers, r(34) = .49, p = .003. …

Dismantling The Monolith: Post-Media Art And The Culture Of Instability, Nora Almeida

Publications and Research

Art that falls under the “new media” paradigm is problematic, or rather, it renders many traditional assumptions about art as problematic. In a practical sense, new media art raises fundamental questions about the nature of curation and preservation and the role of cultural heritage institutions as stewards of digital assets. Curation and preservation challenges, while significant, are fundamentally a symptom of a more catastrophic failure of concepts and language to adequately address changing relationships between art, materiality, and audiences. This article explores how burgeoning concepts in information and media theory may help shape curation contexts and redefine approaches to preservation. …

Transforming Student Engagement Through Documentary And Critical Media Literacy, Jessie Daniels

Publications and Research

Young people entering college today have grown up in a multimedia environment, yet the classroom they most often encounter reflects nineteenth-century pedagogy. This paper explores the paradigm shift that is making documentaries more widely accessible for use in the classroom; describes a pedagogical strategy for connecting a critical media literacy ‘reading’ of documentaries with more traditional reading of written texts; investigates the effectiveness of this method to engage students through critical media literacy in ways that encourage transformation. Effectiveness was measured in a voluntary, self-reported questionnaire, emailed to students after the semester they took Introductory Sociology. Students in the sample …

Where From Here? Ideological Perspectives On The Future Of The Civil Rights Movement, 1964-1966, Kristopher B. Burrell

Publications and Research

Many civil rights movement activist-intellectuals declared that the movement was in a state of "crisis" by the mid-1960s. This article discusses how four black intellectuals--Kenneth Clark, Bayard Rustin, George Schuyler, and Malcolm X--from different ideological perspectives responded to the perception that the movement was in crisis and examines how their ideological underpinnings affected their policy proposals for achieving black equality in the United States. These leaders also wanted to ensure the continued relevance of the movement for racial equality in the United States.

Estimation Of Phosphorus Bioavailability In The Water Column Of The Bronx River, New York, Jingyu Wang, Hari K. Pant

Publications and Research

Phosphorus (P) is a primary limiting nutrient in rivers and streams, and excessive P results in eutrophication of freshwater systems, in turn, excessive algal growth/toxic algal blooms, oxygen depletion, and water quality degradation. This study analyzed P pool, and hydrolysis of organic P (OP) by native phosphatases (NPase) in the water samples collected in the Bronx River. The soluble reactive P (SRP) of most of the sites’ water collected in 2006 and 2007 were higher (average 67 µg·L–1 and 68 µg·L–1, respectively) than the US Environmental Protection Agency’s (EPA) standard of 15 µg·L–1. The SRP% (SRP/TP%) average was 27% in …

Delegated Performance: Outsourcing Authenticity, Claire Bishop

Publications and Research

An essay is presented on delegated performance in which nonprofessionals are hired to perform at a particular time on behalf of the artist on his or her instructions. The author stated that this social turn started since 1990s in contemporary art against the tradition of 1960s and 1970s where artists like Chris Burden, Vito Acconci and Gina Pane performed themselves. The author referred to the trend of live installation started in Europe in 1990s in which guards for exhibition were hired. The Italian artist Maurizio Cattelan assembled a soccer club of foreigners to play local matches in 1991.

From Art On The Wall To Something For All: How An Academic Library Turned Its Art Collection Into A Campus Attraction, Miriam B. Deutch, Jill Cirasella

Publications and Research

An important feature of the Brooklyn College Library is its art collection, the college’s only permanent art collection. In this article, we explain how the library came to have an art collection; how we supplemented the collection with museum-style wall labels, an online catalog, and an audio tour; and how we promoted the collection and sparked student creativity with an annual art contest. We pay particular attention to the decisions and details that might help other libraries working on similar projects.

Isolation And Biophysical Study Of Fruit Cuticles, Subhasish Chatterjee, Sayantani Sarkar, Julia Oktawiec, Zhantong Mao, Olivia Niitsoo, Ruth E. Stark

Publications and Research

The cuticle, a hydrophobic protective layer on the aerial parts of terrestrial plants, functions as a versatile defensive barrier to various biotic and abiotic stresses and also regulates water flow from the external environment.1 A biopolyester (cutin) and long-chain fatty acids (waxes) form the principal structural framework of the cuticle; the functional integrity of the cuticular layer depends on the outer 'epicuticular' layer as well as the blend consisting of the cutin biopolymer and 'intracuticular' waxes.2 Herein, we describe a comprehensive protocol to extract waxes exhaustively from commercial tomato (Solanum lycopersicum) fruit cuticles or to remove epicuticular and intracuticular waxes …

Nongenomic Mechanisms Of Pten Regulation, Jimmie E. Fata, Shawon Debnath, Edmund C. Jenkins, Marcia V. Fournier

Publications and Research

A large amount of data supports the view that PTEN is a bona fide tumor suppressor gene. However, recent evidence suggests that derailment of cellular localization and expression levels of functional nonmutated PTEN is a determining force in inducing abnormal cellular and tissue outcomes. As the cellular mechanisms that regulate normal PTEN enzymatic activity resolve, it is evident that deregulation of these mechanisms can alter cellular processes and tissue architecture and ultimately lead to oncogenic transformation. Here we discuss PTEN ubiquitination, PTEN complex formation with components of the adherens junction, PTEN nuclear localization, and microRNA regulation of PTEN as essential …

Using Avhrr-Based Vegetation Health Indices For Estimation Of Potato Yield In Bangladesh, Rahman A., Kaiser Khan, Nir Y. Krakauer, Leonid Roytman, Kogan F.

Publications and Research

We developed a model correlating Advanced Very High Resolution Radiometer (AVHRR)-based Temperature Condition Index (TCI) and Vegetation Condition Index (VCI) with potato yield in Bangladesh. Weekly TCI and VCI Indices for 1993–2005 along with official potato yield statistics were used for model development. We found a strong correlation between inter annual variation in potato yield and TCI and VCI during the critical period of potato growth (vegetative phase and tuber initiation), mid-December to mid-January. Principal component regression (PCR) was used to construct a model to predict potato yield as function of TCI and VCI. The model explained about 75% of …

In Pursuit Of The Individual In The Field Of Knowledge Management, Isabel D. W. Rechberg, Jawad Syed

Publications and Research

The aim of this paper is to explore the focus on individuals in the field of knowledge management (KM). Through a meta-review of the KM literature, we identify a relative disregard of the individual in the KM literature while information technology (IT) oriented concepts are widely represented. Our review indicates the need for a greater emphasis on individuals in KM as knowledge is based on individuals’ ability and willingness to create, share and transfer knowledge. We offer suggestions on how to integrate individuals into theorising and enacting KM and also identify some avenues for future research.

Using Equivalence-Based Instruction To Increase Efficiency In Teaching Neuroanatomy, Carolyn L. Pytte, Daniel M. Fienup

Publications and Research

A goal of all instruction is to efficiently allocate time spent teaching -- balancing redundancy that enhances learning with redundancy that is irrelevant to increasing student understanding. Efficient allocation of time allows the instructor to present additional material and go into more detail about the information being presented. Here we borrow laboratory research on concept formation and apply these formal principles in teaching introductory neuroanatomy within a lecture course on Behavioral Neuroscience. Concept formation is taught by pairing multiple stimuli, for instance brain name, location, and function, in such a way that novel associations within a category emerge without direct …

Entropy And The Complexity Of Graphs Revisited, Abbe Mowshowitz, Matthias Dehmer

Publications and Research

This paper presents a taxonomy and overview of approaches to the measurement of graph and network complexity. The taxonomy distinguishes between deterministic (e.g., Kolmogorov complexity) and probabilistic approaches with a view to placing entropy-based probabilistic measurement in context. Entropy-based measurement is the main focus of the paper. Relationships between the different entropy functions used to measure complexity are examined; and intrinsic (e.g., classical measures) and extrinsic (e.g., Körner entropy) variants of entropy-based models are discussed in some detail.

The Logic Of Fashion Cycles, Alberto Acerbi, Stefano Ghirlanda, Magnus Enquist

Publications and Research

Many cultural traits exhibit volatile dynamics, commonly dubbed fashions or fads. Here we show that realistic fashion-like dynamics emerge spontaneously if individuals can copy others' preferences for cultural traits as well as traits themselves. We demonstrate this dynamics in simple mathematical models of the diffusion, and subsequent abandonment, of a single cultural trait which individuals may or may not prefer. We then simulate the coevolution between many cultural traits and the associated preferences, reproducing power-law frequency distributions of cultural traits (most traits are adopted by few individuals for a short time, and very few by many for a long time), …

Queensborough Community College: Textbook Reserves, Sheila Beck

Publications and Research

This paper examines the textbook reserve collection at Queensborough Community College. Although the collection is heavily used in its current configuration, the library is looking for less labor intensive and less costly alternatives.

The cost of textbooks is skyrocketting. Textbooks are a major, unexpected bill for many students beginning college. Students and their family, used to having their textbooks provided or loaned free of charge at the start of the school year, face often large and unexpected bills when the first term begins. Many times, financial aid does not cover the cost of the books;. Even if it is covered …

Epidemiology And Management Of Depression Following Coronary Heart Disease Diagnosis In Women, Siqin Ye, Ellen-Ge Denton, Lauren T. Wasson, Karina W. Davidson

Publications and Research

Coronary heart disease (CHD) and depression are both highly prevalent in women. Importantly, depression is associated with significantly elevated morbidity and mortality in women with CHD. There are intriguing speculations about biological mechanisms underlying this association, such as endothelial dysfunction, subclinical atherosclerosis, inflammation, and autonomic dysregulation. Social and behavioral mechanisms, such as lack of social support and physical inactivity, have also been shown to play important roles. Unfortunately, many randomized clinical trials of counseling and pharmacologic interventions for depression in patients with CHD have failed to improve cardiovascular outcomes, and in fact have raised the possibility that interventions might be …

Independent Recruitment Of A Flavin-Dependent Monooxygenase For Safe Accumulation Of Sequestered Pyrrolizidine Alkaloids In Grasshoppers And Moths, Linzhu Wang, Till Beuerle, James Timbilla, Dietrich Ober

Publications and Research

Several insect lineages have developed diverse strategies to sequester toxic pyrrolizidine alkaloids from food-plants for their own defense. Here, we show that in two highly divergent insect taxa, the hemimetabolous grasshoppers and the holometabolous butterflies, an almost identical strategy evolved independently for safe accumulation of pyrrolizidine alkaloids. This strategy involves a pyrrolizidine alkaloid N-oxygenase that transfers the pyrrolizidine alkaloids to their respective N-oxide, enabling the insects to avoid high concentrations of toxic pyrrolizidine alkaloids in the hemolymph. We have identified a pyrrolizidine alkaloid N-oxygenase, which is a flavin-dependent monooxygenase, of the grasshopper Zonocerus variegatus. After heterologous expression in E. coli, …

Sendai Virus-Based Liposomes Enable Targeted Cytosolic Delivery Of Nanoparticles In Brain Tumor-Derived Cells, Veronica Dudu, Veronica Rotari, Maribel Vazquez

Publications and Research

BACKGROUND: Nanotechnology-based bioassays that detect the presence and/or absence of a combination of cell markers are increasingly used to identify stem or progenitor cells, assess cell heterogeneity, and evaluate tumor malignancy and/or chemoresistance. Delivery methods that enable nanoparticles to rapidly detect emerging, intracellular markers within cell clusters of biopsies will greatly aid in tumor characterization, analysis of functional state and development of treatment regimens.

RESULTS: Experiments utilized the Sendai virus to achieve in vitro, cytosolic delivery of Quantum dots in cells cultured from Human brain tumors. Using fluorescence microscopy and Transmission Electron Microscopy, in vitro experiments illustrated that these virus-based …

Voltage Gated Ion Channel Function: Gating, Conduction, And The Role Of Water And Protons, Alisher M. Kariev, Michael E. Green

Publications and Research

Ion channels, which are found in every biological cell, regulate the concentration of electrolytes, and are responsible for multiple biological functions, including in particular the propagation of nerve impulses. The channels with the latter function are gated (opened) by a voltage signal, which allows Na+ into the cell and K+ out. These channels have several positively charged amino acids on a transmembrane domain of their voltage sensor, and it is generally considered, based primarily on two lines of experimental evidence, that these charges move with respect to the membrane to open the channel. At least three forms of motion, with …

A Swot Model Of The Challenges And Benefits Of Volunteer Involvement In Us Non-Profit Organisations During Times Of Fiscal Stress, Helisse Levine, Maria J. D’Agostino

Publications and Research

As a result of the current fiscal crisis, the US Federal Government is calling on non-profit organisations and communities across the country to contribute their service through volunteering. This study uses qualitative data retrieved from a purposive sample of New York City non-profit administrators to determine the challenges and benefits of volunteer involvement in US non-profit organisations during the economic downturn that began in 2008. Findings conclude that although US Federal Government initiatives, including $50 million of the American Recovery and Reinvestment Act allocated to the strengthening communities fund provided non-profits the opportunity to draw on an influx of a …

Aligned Layers Of Silver Nano-Fibers, Andrii B. Golovin, Jeremy Stromer, Liubov Kreminska

Publications and Research

We describe a new dichroic polarizers made by ordering silver nano-fibers to aligned layers. The aligned layers consist of nano-fibers and self-assembled molecular aggregates of lyotropic liquid crystals. Unidirectional alignment of the layers is achieved by means of mechanical shearing. Aligned layers of silver nano-fibers are partially transparent to a linearly polarized electromagnetic radiation. The unidirectional alignment and density of the silver nano-fibers determine degree of polarization of transmitted light. The aligned layers of silver nano-fibers might be used in optics, microwave applications, and organic electronics.

Pten Regulation Of Local And Long-Range Connections In Mouse Auditory Cortex, Qiaojie Xiong, Hysell V. Oviedo, Lloyd C. Trotman, Anthony M. Zador

Publications and Research

Autism spectrum disorders (ASDs) are highly heritable developmental disorders caused by a heterogeneous collection of genetic lesions. Here we use a mouse model to study the effect on cortical connectivity of disrupting the ASD candidate gene PTEN (phosphatase and tensin homolog deleted on chromosome 10). Through Cre-mediated recombination, we conditionally knocked out PTEN expression in a subset of auditory cortical neurons. Analysis of long-range connectivity using channelrhodopsin-2 revealed that the strength of synaptic inputs from both the contralateral auditory cortex and from the thalamus onto PTEN-cko neurons was enhanced compared with nearby neurons with normal PTEN expression. Laser-scanning photostimulation showed …

Serotonin 1a Receptor-Mediated Signaling Through Erk And Pkcα Is Essential For Normal Synaptogenesis In Neonatal Mouse Hippocampus, A. Mogha, Sara R. Guariglia, Priya Ranjan Debata, Guang Y. Wen, Probal Banerjee

Publications and Research

Aberrant expression of the presynaptic serotonin 1A receptor (5-HT_1A-R) because of a polymorphism in the 5-HT_1A-R gene is associated with severe depression in human, whereas its absence up to postnatal day 21 (P21) in the forebrain of mice results in heightened anxiety in adulthood. These observations collectively indicate that the 5-HT1A-R has a crucial role in brain development. To understand the mechanistic underpinnings of this phenomenon, we used organotypic slice cultures of hippocampi from C57BL6 mice (C57) at P15, which coincides with the peak of neonatal synaptogenesis. Stimulation of the hippocampal 5-HT1A-R caused a dramatic increase …

Relationships Between Urinary Biomarkers Of Phytoestrogens, Phthalates, Phenols, And Pubertal Stages In Girls, Tandra R. Chakraborty, Eilliut Alicea, Sanjoy Chakraborty

Publications and Research

Phytoestrogens, phthalates, and phenols are estrogen-disrupting chemicals that have a pronounced effect at puberty. They are exogenous chemicals that are either plant-derived or man-made, and can alter the functions of the endocrine system and cause various health defects by interfering with the synthesis, metabolism, binding, or cellular responses of natural estrogens. Phytoestrogens, phthalates, and phenols are some of the potent estrogens detectable in urine. Phytoestrogens are plant-derived xenestrogens found in a wide variety of food products, like soy-based food, beverages, several fruits, and vegetables. Exposure to phytoestrogens can delay breast development and further lead to precocious puberty. The effect of …
