Does Applying Deep Learning In Financial Sentiment Analysis Lead To Better Classification Performance?, Tao Wang, Changhe Yuan, Cuiyuan Wang

Publications and Research

Using a unique data set from Seeking Alpha, we compare the deep learning approach with traditional machine learning approaches in classifying financial text. We apply the long short-term memory (LSTM) as the deep learning method and Naive Bayes, SVM, Logistic Regression, XGBoost as the traditional machine learning approaches. The results suggest that the LSTM model outperforms the conventional machine learning methods on all metrics. Based on the tSNE graph, the success of the LSTM model is partially explained as the high-accuracy LSTM model distinguishes between positive and negative important sentiment words while those words are chosen based on SHAP values …

In this study, researchers observed the impact of various promotional materials, such as print flyers, social media, email, and other web platforms, to market three electronic resources at a mid-sized, urban, commuter college academic library. Links to article databases were shortened and then tracked through a link shortening tool, which were observed over a two month period. The results created a data-driven picture of users’ promotional preferences, highlighting strengths, areas for improvement, and best practices in marketing e-resources. These best practices can be implemented at other libraries and the study methodology can be applied to other institutions tailoring their promotional …

Beyond The Market: A “Public-Commons-Partnership” For Housing, Arielle Lawson

Publications and Research

The commodification of housing has led to new levels of unaffordability for tenants all over the country. With skyrocketing rents and an explosion of homelessness, we are faced with the glaring failures of our capitalist housing system to meet people’s most basic human needs. Recognizing the inherent limitations of “affordable housing” within a profit-driven system, we need a paradigm shift around housing that can change the terms of the debate, and advance a real alternative to the speculative market. A growing housing justice movement — combined with a renewed politicization of tenants — is leading the way. From new rent …

The White Album As Neo-Victorian Fiction Of Loss, Lucas Kwong

Publications and Research

Although much has been written about the Beatles' celebration of Victorian culture on the album Sgt. Pepper's Lonely Hearts Club Band, little scholarship, if any, has focused on the White Album’s relationship to the late Victorian period. This paper examines the White Album through the lens of what Victorian studies scholar Stephen Arata has called “fictions of loss,” a body of late Victorian texts depicting intertwined processes of “national, biological, [and] aesthetic” decline. Through examining songs like "Helter Skelter" and "Revolution Number 9," I argue that the White Album deserves consideration alongside Dracula and She as a “fiction of loss,” …

The Ends Of Medicine And The Experience Of Patients, D. Robert Macdougall

Publications and Research

The ends of medicine are sometimes construed simply as promotion of health, treatment and prevention of disease, and alleviation of pain. Practitioners might agree that this simple formulation captures much of what medical practice is about. But while the ends of medicine may seem simple or even obvious, the essays in this issue demonstrate the wide variety of philosophical questions and issues associated with the ends of medicine. They raise questions about how to characterize terms like “health” and “disease”; whether medicine’s goals should be extended to include enhancement beyond normal human function; and whether the ends of medicine are …

Supporting Twenty-First-Century Students With An Across-The-Curriculum Approach To Undergraduate Research, Patrick Corbett, Jody R. Rosen

Publications and Research

An across-the-curriculum (ATC) approach to undergraduate research (UR) is a productive addition to UR ecosystems at equity-oriented institutions. The ATC approach is differentiated from mentored UR experiences and laboratory course-based UR experiences by its ability to employ experiential, problem-based skills and practices for a broad variety of informal research activities at all levels of curriculum and without special facilities. In doing so, the ATC model encourages faculty to make the application of twenty-first-century student learning outcomes explicit for students who are new to research so that they see how inquiry, knowledge creation, and other aspects of problem-solving are used in …

Out Of The Archives And Into The Streets: Teaching With Primary Sources To Cultivate Civic Engagement, Jen Hoyer

A Micro-Optic Stalk (Muos) System To Model The Collective Migration Of Retinal Neuroblasts, Stephanie Zhang, Miles Markey, Caroline D. Pena, Tadmiri Venkatesh, Maribel Vasquez

Publications and Research

Contemporary regenerative therapies have introduced stem-like cells to replace damaged neurons in the visual system by recapitulating critical processes of eye development. The collective migration of neural stem cells is fundamental to retinogenesis and has been exceptionally well-studied using the fruit fly model of Drosophila Melanogaster. However, the migratory behavior of its retinal neuroblasts (RNBs) has been surprisingly understudied, despite being critical to retinal development in this invertebrate model. The current project developed a new microfluidic system to examine the collective migration of RNBs extracted from the developing visual system of Drosophila as a model for the collective motile processes …

Fibration Symmetries Uncover The Building Blocks Of Biological Networks, Flaviano Morone, Ian Leifer, Hernán A. Makse

Publications and Research

A major ambition of systems science is to uncover the building blocks of any biological network to decipher how cellular function emerges from their interactions. Here, we introduce a graph representation of the information flow in these networks as a set of input trees, one for each node, which contains all pathways along which information can be transmitted in the network. In this representation, we find remarkable symmetries in the input trees that deconstruct the network into functional building blocks called fibers. Nodes in a fiber have isomorphic input trees and thus process equivalent dynamics and synchronize their activity. Each …

Feminist Pedagogy In A Time Of Coronavirus Pandemic, Alexandra Juhasz, Laura Wexler, Liz Losh, Sharon Irish

Publications and Research

FemTechNet, a network of scholars, artists, and students working on, with, and at the borders of technology, science, and feminism, has a great deal of experience thinking about pedagogy and technology. We have produced real intimacy, vibrant classes, and insurgent pedagogy since 2012. The principles of our signature Distributed Open Collaborative Courses (DOCCs) are crucial (see below). In this time of crisis, we believe we need to think again, drawing the most power possible from the radical knowledges, tactics, and commitments of feminist pedagogies of past experience. We write while schools, colleges, and universities have closed in a cascade of …

The article ends with a discussion of specific steps for teaching mathematics that put the identity of those from traditionally marginalized communities at the …

C-Di-Gmp Modulates Type Iv Msha Pilus Retraction And Surface Attachment In Vibrio Cholerae, Kyle A. Floyd, Calvin K. Lee, Wujing Xian, Mahmoud Nametalla, Aneesa Valentine, Benjamin Crair, Shiwei Zhu, Hannah Q. Hughes, Jennifer L. Chlebek, Daniel C. Wu, Jin Hwan Park, Ali M. Farhat, Charles J. Lomba, Courtney K. Ellison, Yves V. Brun, Javier Campos-Gomez, Ankur B. Dalia, Jun Liu, Nicolas Biais, Gerard C. L. Wong, Fitnat H. Yildiz

Publications and Research

Biofilm formation by Vibrio cholerae facilitates environmental persistence, and hyperinfectivity within the host. Biofilm formation is regulated by 3’,5’-cyclic diguanylate (c-di-GMP) and requires production of the type IV mannose-sensitive hemagglutinin (MSHA) pilus. Here, we show that the MSHA pilus is a dynamic extendable and retractable system, and its activity is directly controlled by c-di-GMP. The interaction between c-di-GMP and the ATPase MshE promotes pilus extension, whereas low levels of c-di-GMP correlate with enhanced retrac- tion. Loss of retraction facilitated by the ATPase PilT increases near-surface roaming motility, and impairs initial surface attachment. However, prolonged retraction upon surface attach- ment results …

Accumulation Of Unacetylatable Snf2p At The Ino1 Promoter Is Detrimental To Remodeler Recycling Supply For Cup1 Induction, Michelle Esposito, Goldie Libby Sherr, Anthony Esposito, George Kaluski, Farris Ellington, Chang-Hui Shen

Publications and Research

Chromatin structure plays a decisive role in gene regulation through the actions of transcriptional activators, coactivators, and epigenetic machinery. These trans-acting factors contribute to gene expression through their interactions with chromatin structure. In yeast INO1 activation, transcriptional activators and coactivators have been defined through intense study but the mechanistic links within these trans-acting factors and their functional implications are not yet fully understood. In this study, we examined the crosstalk within transcriptional coactivators with regard to the implications of Snf2p acetylation during INO1 activation. Through various biochemical analysis, we demonstrated that both Snf2p and Ino80p chromatin remodelers accumulate …

Microfluidic Study Of The Electrocoalescence Of Aqueous Droplets In Crude Oil, Thomas Leary, Mohsen Yeganeh, Charles Maldarelli

Publications and Research

In electrocoalescence, an electric field is applied to a dispersion of conducting water droplets in a poorly conducting oil to force the droplets to merge in the direction of the field. Electrocoalescence is used in petroleum refining to separate water from crude oil and in droplet-based microfluidics to combine droplets of water in oil and to break emulsions. Using a microfluidic design to generate a two-dimensional (2D) emulsion, we demonstrate that electrocoalescence in an opaque crude oil can be visualized with optical microscopy and studied on an individual droplet basis in a chamber whose height is small enough to make …

Publications and Research

The novel coronavirus COVID-19 has profoundly disrupted life in the United States. Among other challenges, jurisdictions are unlikely to be able to administer the July 2020 bar exam in the usual manner. It is essential, however, to continue licensing new lawyers. Those lawyers are necessary to meet current needs in the legal system. Equally important, the demand for legal services will skyrocket during and after this pandemic. We cannot close doors to the profession at a time when client demand will reach an all-time high.

In this brief policy paper, we outline six licensing options for jurisdictions to consider for …

Schoenfeld, Gøran Paulsen, Thomas Bjørnsen, Kristoffer T. Cumming, Per Aagaard, Brian C. Clark, Truls Raastad

Publications and Research

Low-load exercise combined with blood flow restriction (BFR) is known to induce significant gains in muscle strength and size, and this mode of training is increasingly used in both healthy and clinical populations, as documented in the recent review of Patterson et al. (2019). However, since the first training studies on BFR exercise appeared about 20 years ago, there have been some concerns about its safety, in particular with regard to the potential risk for muscle damage (Wernbom et al., 2019). In a recent editorial, Wernbom et al. (2019) briefly discussed the accumulating evidence for muscle damage and rhabdomyolysis with …

Metabolic Reprogramming By C-Met Inhibition As A Targetable Vulnerability In Glioblastoma, Trang Thi Thu Nguyen, Enyuan Shang, Georg Karpel-Massler, Markus D. Siegelin

Publications and Research

The elucidation of better treatments for solid tumors and especially malignant glial tumors is a priority. Better understanding of the molecular underpinnings of treatment response and resistance are critical determinants in the success for this endeavor. Recently, a battery of novel tools have surfaced that allow to interrogate tumor cell metabolism to more precise extent than this was possible in the earlier days. At the forefront of these developments are the extracellular flux and carbon tracing analyses. Through utilization of these techniques our group made the recent observation that acute and chronic c-MET inhibition drives fatty acid oxidation that in …

From Brooklyn To “Brooklyn” The Cultural Transformations Of Leisure, Pleasure, And Taste, Emily Holloway

Publications and Research

To tell the story of Brooklyn’s complex history in hospitality and cuisine is to tell a story about the tensions of high and low culture, of the mobility of capital and residents, and of the tremendous influence yielded by macroeconomic change. A sleepy bedroom community for the eighteenth and much of the early nineteenth centuries, Brooklyn’s waterfront (both historically and today) is deeply tied to its nineteenth and twentieth-century industrial heritage. The ad hoc economies that supported factory and dock workers, included boardinghouses, saloons, brothels, food carts, and amusement parks and drew a stark contrast to those of factory and …

Transcutaneous Auricular Vagus Nerve Stimulation-Paired Rehabilitation For Oromotor Feeding Problems In Newborns: An Open-Label Pilot Study, Bashar W. Badran, Dorothea D. Jenkins, Daniel Cook, Sean Thompson, Morgan Darcy, William H. Devries, Georgia Mappin, Philipp Summers, Marom Bikson, Mark S. George

Publications and Research

Neonates born premature or who suffer brain injury at birth often have oral feeding dysfunction and do not meet oral intake requirements needed for discharge. Low oral intake volumes result in extended stays in the hospital (>2 months) and can lead to surgical implant and explant of a gastrostomy tube (G-tube). Prior work suggests pairing vagus nerve stimulation (VNS) with motor activity accelerates functional improvements after stroke, and transcutaneous auricular VNS (taVNS) has emerged as promising noninvasive form of VNS. Pairing taVNS with bottle-feeding rehabilitation may improve oromotor coordination and lead to improved oral intake volumes, ultimately avoiding the …
