Leveraging Learning To Improve Disaster Management Outcomes, Denise D. P. Thompson

Publications and Research

Disaster management agencies should be exemplars of learning given the volatility of their operating environment. However, there are cognitive, social, and organizational barriers that prevent these organizations from learning. The purpose of this article is to use the Caribbean Disaster and Emergency Management Agency (CDEMA) as an example of an organization that achieves double-loop learning in spite of known barriers. This research shows significant learning variations in the CDEMA organization from the regional to the national level. The results demonstrate that the CDEMA Coordinating Unit and a few national member agencies achieve double-loop learning, while the opposite is true for …

A Kitchen Of One's Own: The Paradox Of Dione Lucas, Kathleen Collins

Publications and Research

First appearing on the air in 1947, Dione Lucas was one of the earliest television cooking-show hosts. As a business owner, single mother, influential salesperson, and highly respected professional in her field (Julia Child referred to Lucas as “the mother of French cooking in America”), Lucas was a pioneer and potentially powerful role model. Given this profile, however, she was an anachronism and out of sync with the majority of contemporary women and home cooks. She was likewise out of sync with her television peers, as most homemaking programs were hosted by home economists and were contexts wherein thrift and …

Hyphens For Disambiguating Phrases: Effectiveness For Young And Older Adults, Inge Anema, Loraine Obler

Publications and Research

The purpose of this study was to investigate whether hyphens that disambiguate phrasing in ambiguous sentences influence reading rate and reading comprehension for younger and older adults. Moreover, as working memory (WM) has been implicated in age-related changes in sentence comprehension for both auditory and written materials, we asked if it contributed to comprehension of our sentences with hyphenated and non-hyphenated ambiguous noun phrases (NPs), predicting that the hyphens would reduce WM load. Twenty younger (M = 24 years) and 20 older (M = 73 years) adults read sentences with either ambiguous or non-ambiguous NPs that were either hyphenated or …

This chapter evaluates the ways DH practices, embodied in a series of pedagogy projects at the City University of York (CUNY), have been used to reshape teaching and learning in college classrooms.

Digital Video: Engaging Students In Critical Media Literacy And Community Activism, Jessie Daniels

Publications and Research

This article presents a strategy for teaching health communication that fosters critical media literacy through the strategic combination of digital video, documentary film, video worksheets, and peer-reviewed journal articles. Given the media-saturated environment in which notions of health are shaped, critical media literacy skills are crucial to students in health-related fields. Cases of key concepts illustrated through documentary films and the peer-reviewed literature are presented. The article then explores how one class took the lead in designing a community event that critically engaged both a YouTube video and a documentary film about police brutality as a public health issue.

Topic Modeling And Figurative Language, Lisa M. Rhody

Publications and Research

Located at the center of Jorie Graham’s collection The End of Beauty, “Self Portrait as Hurray and Delay” crafts a portrait of the artist, poised at a precarious moment in which thought begins to take shape. Like Penelope, Graham entertains the illusion, if only momentarily, of a choice between bringing a creative impulse into form or allowing it to come undone. A weaver of language, Graham subtly, deftly, but unsuccessfully attempts to delay the inevitable moment in poetic creation in which complexity of thought adopts form through language, and so realized is also reduced. In The End of Beauty, the …

The Social Life Of Musical Instruments, Eliot Bates

Publications and Research

Accordion Crimes, a novel by E. Annie Proulx, traces the life of and routes travelled by a green diatonic button accordion: its birth in Sicily in the workshop of “The Accordion Maker,” its numerous changes of ownership in the Americas during encounters between various immigrant communities, and its death when it finally falls into disrepair in the town of Old Glory, Minnesota. There are other accordions in the book, and many temporary human owners, but it is one particular green accordion that is the book’s protagonist. We meet and experience other characters largely through their interactions with the green accordion, …

Arsenic Migration To Deep Groundwater In Bangladesh Influenced By Adsorption And Water Demand, K.A. Radloff, Y. Zheng, H.A. Michael, M. Stute, B. C. Bostick, I. Mihajlov, M. Bounds, M. R. Huq, I. Choudhury, M. W. Rahman, P. Schlosser, K. M. Ahmed, A. Van Geen

Publications and Research

Drinking shallow groundwater with naturally elevated concentrations of arsenic is causing widespread disease in many parts of South and Southeast Asia. In the Bengal Basin, growing reliance on deep (>150 m) groundwater has lowered exposure. In the most affected districts of Bangladesh, shallow groundwater concentrations average 100 to 370 μg L−1, while deep groundwater is typically < 10 μg L−1. Groundwater flow simulations have suggested that, even when deep pumping is restricted to domestic use, deep groundwater in some areas of the Bengal Basin is at risk of contamination. However, these simulations have neglected the impedance of As migration by adsorption to aquifer sediments. Here we quantify for the first time As sorption on deeper sediments in situ by replicating the intrusion of shallow groundwater through injection of 1,000 L of deep groundwater modified with 200 μg L−1 of As into a deeper aquifer. Arsenic concentrations in the injected water were reduced by 70% due to adsorption within a single day. Basin-scale modelling indicates that while As adsorption extends the sustainable use of deep groundwater, some areas remain vulnerable; these areas can be prioritized for management and monitoring.

Sexuality, Rights And Personhood: Tensions In A Transnational World, Dina M. Siddiqi

Publications and Research

Background This article discusses what happens when normative ‘global’ discourses of rights and individuated sexual identity confront the messiness of ‘local’ realities. It considers the tensions that emerge when the relationship between sexual and social identities is not obvious and the implications of such tensions for public health and sexual rights activism. These questions are addressed through debates over the naming of male-to-male sexualities and desires in the context of globalization and the growth of a large NGO (non-governmental organization) sector in urban Bangladesh. Methods The material in the paper draws on a research project undertaken in 2008-9 in Dhaka, …

Publications and Research

Background Abnormal white matter development may disrupt integration within neural circuits, causing particular impairments in higher-order behaviours. In autism spectrum disorders (ASDs), white matter alterations may contribute to characteristic deficits in complex socio-emotional and communication domains. Here, we used diffusion tensor imaging (DTI) and tract based spatial statistics (TBSS) to evaluate white matter microstructure in ASD. Methods/Principal Findings DTI scans were acquired for 19 children and adolescents with ASD (∼8–18 years; mean 12.4±3.1) and 16 age and IQ matched controls (∼8–18 years; mean 12.3±3.6) on a 3T MRI system. DTI values for fractional anisotropy, mean diffusivity, radial diffusivity and axial …

Phylogenomics Of Reichenowia Parasitica, An Alphaproteobacterial Endosymbiont Of The Freshwater Leech Placobdella Parasitica, Sebastian Kvist, Apurva Narechania, Alejandro Oceguera-Figueroa, Bella Fuks, Mark E. Siddall

Publications and Research

Although several commensal alphaproteobacteria form close relationships with plant hosts where they aid in (e.g.,) nitrogen fixation and nodulation, only a few inhabit animal hosts. Among these, Reichenowia picta, R. ornata and R. parasitica, are currently the only known mutualistic, alphaproteobacterial endosymbionts to inhabit leeches. These bacteria are harbored in the epithelial cells of the mycetomal structures of their freshwater leech hosts, Placobdella spp., and these structures have no other obvious function than housing bacterial symbionts. However, the function of the bacterial symbionts has remained unclear. Here, we focused both on exploring the genomic makeup of R. parasitica and on …

Solution Structure And Dna-Binding Properties Of The Phosphoesterase Domain Of Dna Ligase D, Aswin Natarajan, Kaushik Dutta, Deniz B. Temel, Pravin A. Nair, Stewart Shuman, Ranajeet Ghose

Publications and Research

The phosphoesterase (PE) domain of the bacterial DNA repair enzyme LigD possesses distinctive manganese-dependent 3'-phosphomonoesterase and 3'-phosphodiesterase activities. PE exemplifies a new family of DNA end-healing enzymes found in all phylogenetic domains. Here, we determined the structure of the PE domain of Pseudomonas aeruginosa LigD (PaePE) using solution NMR methodology. PaePE has a disordered N-terminus and a well-folded core that differs in instructive ways from the crystal structure of a PaePE•Mn(2+)• sulfate complex, especially at the active site that is found to be conformationally dynamic. Chemical shift perturbations in the presence of primertemplate duplexes with 30-deoxynucleotide, …

Progesterone-Induced Changes In The Phosphoryl Potential During The Meiotic Divisions In Amphibian Oocytes: Role Of Na/K-Atpase, Gene A. Morrill, Terry L. Dowd, Adele B. Kostellow, Raj K. Gupta

Publications and Research

Background Progesterone triggers resumption of the first meiotic division in the Rana pipiens oocyte by binding to the N-terminal external loop of the catalytic subunit of Na/K-ATPase, releasing a cascade of lipid second messengers. This is followed by internalization of specific membrane proteins, plasma membrane depolarization and nuclear membrane breakdown, culminating in arrest at second metaphase. Results Progesterone initiates an increase in phosphoryl potential during the first meiotic division, resulting in the accumulation of high energy protein phosphate by second metaphase arrest. 31P-NMR, with saturation transfer, demonstrates that the phosphocreatine level rises ~2 fold and that the "pseudo" first order …

Migration And Invasion Of Brain Tumors, Richard A. Able, Jr., Veronica Dudu, Maribel Vazquez

Publications and Research

Recent advances in molecular biology have led to new insights in the development, growth and infiltrative behaviors of primary brain tumors (Demuth and Berens, 2004; Huse and Holland, 2010; Johnson et al., 2009; Kanu et al., 2009). These tumors are derived from various brain cell lineages and have been historically classified on the basis of morphological and, more recently, immunohistochemical features with less emphasis on their underlying molecular pathogenesis (Huse and Holland, 2010). The detailed molecular characterization of brain tumors has laid the groundwork for augmentation of standard treatment with patient-specific designed targeted therapies (Johnson et al., 2009; Kanu et …

Time Reversal Optical Tomography: Locating Targets In A Highly Scattering Turbid Medium, Binlin Wu, W. Cai, M. Alrubaiee, M. Xu, S. K. Gayen

Publications and Research

A time reversal optical tomography (TROT) method for near-infrared (NIR) diffuse optical imaging of targets embedded in a highly scattering turbid medium is presented. TROT combines the basic symmetry of time reversal invariance and subspace-based signal processing for retrieval of target location. The efficacy of TROT is tested using simulated data and data obtained from NIR imaging experiments on absorptive and scattering targets embedded in Intralipid-20% suspension in water, as turbid medium. The results demonstrate the potential of TROT for detecting and locating small targets in a turbid medium, such as, breast tumors in early stages of growth.
