‘Multiple Forecast Visualizations (MFVs): Trade-offs in Trust and Performance in Multiple COVID-19 Forecast Visualizations’
“The prevalence of inadequate SARS-COV-2 (COVID-19) responses may indicate a lack of trust in forecasts and risk communication. However, no work has empirically tested how multiple forecast visualization choices impact trust and task-based performance. The three studies presented in this paper ( N=1299 ) examine how visualization choices impact trust in COVID-19 mortality forecasts and how they influence performance in a trend prediction task.” Read “Multiple Forecast Visualizations (MFVs): Trade-offs in Trust and Performance in Multiple COVID-19 Forecast Visualizations” and see the full list of authors in IEEE Transactions on Visualization and Computer Graphics.

‘Image-Text Embedding Learning via Visual and Textual Semantic Reasoning’
“As a bridge between language and vision domains, cross-modal retrieval between images and texts is a hot research topic in recent years. It remains challenging because the current image representations usually lack semantic concepts in the corresponding sentence captions. To address this issue, we introduce an intuitive and interpretable model to learn a common embedding space for alignments between images and text descriptions.” Read the paper and see the full list of authors IEEE Transactions on Pattern Analysis and Machine Intelligence.

‘Data Lake Organization’
“We consider the problem of building an organizational directory of data lakes to support effective user navigation. The organization directory is defined as an acyclic graph that contains nodes representing sets of attributes and edges indicating subset relationships between nodes. A probabilistic model is constructed to model user navigational behaviour. The model also predicts the likelihood of users finding relevant tables in a data lake given an organization.” Read the paper and see the full list of authors in IEEE Transactions on Knowledge and Data Engineering.

‘Not Your Average App: A Large-Scale Privacy Analysis of Android Browsers’
“Mobile browsers may present contradicting privacy behaviors. On the one end, they can have access to (and can expose) a unique combination of sensitive user data. … However, on the other end, they also are in a unique position to protect users’ privacy by limiting data sharing with other parties by implementing ad-blocking features. In this paper, we perform a comparative and empirical analysis on how hundreds of Android web browsers protect or expose user data during browsing sessions.” Read the paper and see the full list of authors in the Proceedings on Privacy Enhancing Technologies Symposium.

‘GenoREC: A Recommendation System for Interactive Genomics Data Visualization’
“Interpretation of genomics data is critically reliant on the application of a wide range of visualization tools. A large number of visualization techniques for genomics data and different analysis tasks pose a significant challenge. … Since genomics analysts typically have limited training in data visualization, their choices are often based on trial and error or guided by technical details. … To address these challenges, we designed GenoREC, a novel visualization recommendation system for genomics. GenoREC enables genomics analysts to select effective visualizations.” Read the paper and see the full list of authors in IEEE Transactions on Visualization and Computer Graphics.

‘Photosensitive Accessibility for Interactive Data Visualizations’
“We systematically gathered and tested 1,132 interactive and animated visualizations for seizure-inducing risk using established methods and found that currently available methods for determining photosensitive risk are not reliable when evaluating interactive visualizations, as risk scores varied significantly based on the individual interacting with the visualization. To address this issue, we introduce a theoretical model defining the degree of control visualization designers have over three determinants of photosensitive risk in potentially seizure-inducing sequences: the size, frequency, and color of flashing content.” Read the paper and see the full list of authors in IEEE Transactions on Visualization and Computer Graphics.

‘Learning How To Listen: Automatically Finding Bug Patterns in Event-Driven JavaScript APIs’
“Event-driven programming is widely practiced in the JavaScript community. … Concentrating on the problem of detecting dead listeners, we present an approach to learn how to use event-based APIs by first mining a large corpus of JavaScript code using a simple static analysis to identify code snippets that register an event listener, and then applying statistical modeling to identify anomalous patterns, which often indicate incorrect API usage.” Read the paper and see the full list of authors in IEEE Transactions on Software Engineering.

MRI studies of ‘nonword repetition’ provides insight into brain function of autistic children
Researchers have “used functional magnetic resonance imaging (fMRI) to investigate the brain bases for nonword repetition challenges in autism.” Nonword repetition, or the ability to repeat sounds not associated with a meaning-laden word, is “a common clinical measure of phonological working memory.” Also employing “Multivoxel pattern analysis within the speech production network,” researchers found that their “findings suggest that atypical function in speech production brain regions may contribute to nonword repetition difficulties in autism.” Find “Altered engagement of the speech motor network is associated with reduced phonological working memory in autism” and the full list of authors in NeuroImage: Clinical.

Measuring climate change opinions among recreational fishers and citizen scientists
This paper hopes to understand the climatic opinions held by those involved in non-commercial fisheries. “Past research has focused on climate impacts and adaptation efforts in commercial fisheries,” the authors write, with little attention being spared for “recreational fishers and other stakeholders such as citizen scientists.” Overall, they observed that “Citizen scientists showed greater concern for climate change than recreational fishers and non-fisher/non-citizen scientists.” Read “Catching versus Counting: Comparing the Pro-Environmental Attitudes, Behaviors, and Climate Concerns of Recreational Fishers and Citizen Scientists” and see the full list of authors in Sustainability.

‘Human Motion Segmentation via Velocity-Sensitive Dual-Side Auto-Encoder’
“Human motion segmentation (HMS) aims to segment a long human action video into a bunch of short and meaningful action clips. Existing supervised learning approaches need a large amount of training data which may be costly in real-world scenario, while most unsupervised clustering methods cannot fully explore the temporal correlations among human motions and hard to achieve promising performances. In our paper, we design a novel unsupervised framework, called Velocity-Sensitive Dual-Side Auto-Encoder (VSDA), for HMS task.” Read the paper and see the full list of authors IEEE Transactions on Image Processing.

Associate professor John Bai, in the D’Amore-McKim School of Business, writing with Anya Mkrtchyan from the University of Massachusetts Amherst, uses “rich microdata” from the United States Census Bureau to examine the “relative performance” of new CEOs within a company, comparing CEOs promoted internally with those who are hired externally. Ultimately, their findings “suggest that inside successors might benefit from adopting an outside perspective, demonstrating a sensitivity to change, and challenging legacies and relationships that might diminish their effectiveness.” Read “What Do Outside CEOs Really Do? Evidence from Plant-Level Data” at the Harvard Law School Forum on Corporate Governance.

Breaking through the COVID-19 virus’ shell
A result of a collaboration between labs in Northeastern University’s departments of physics and chemistry, this paper expands on our understanding of SARS-CoV-2, the virus that causes COVID-19. Using optical tweezers, researchers gained “direct measurements” of the SARS-CoV-2 nucleocapsid protein, the “N” protein. These new observations on the virus’s binding process set the stage for future attempts at disrupting the process entirely, targeting the nucleocapsid protein and striking at the virus’s interior. See the full list of authors and read their research, “Structural domains of SARS-CoV-2 nucleocapsid protein coordinate to compact long nucleic acid substrates,” in Nucleic Acids Research.

Phonological knowledge shared by signers and non-signers
In this article, professor of psychology Iris Berent, with professor Judit Gervain from the University of Padua and Université Paris Cité, argues that the knowledge of sign language and of a non-sign language can mutually inform one another. “Informed by recent findings from adults and infants,” they write, “we argue that the phonological system is partly amodal. We show that hearing infants use a shared brain network to extract phonological rules from speech and sign.” Read this discussion paper, “Speakers aren’t blank slates (with respect to sign-language phonology)!” in Cognition.

‘Optimal Recursive Expert-Enabled Inference in Regulatory Networks’
“Accurate inference of biological systems, such as gene regulatory networks and microbial communities, is a key to a deep understanding of their underlying mechanisms. Despite several advances in the inference of regulatory networks in recent years, the existing techniques cannot incorporate expert knowledge into the inference process. … This letter models the regulatory networks using Boolean network with perturbation. We develop an expert-enabled inference method for inferring the unknown parameters of the network model using expert-acquired data.” Read the paper and see the full list of authors IEEE Transactions on Visualization and Computer Graphics.

‘Towards a Unified Drag Coefficient Formula for Quantifying Wave Energy Reduction by Salt Marshes’
“Coastal regions are susceptible to increasing flood risks amid climate change. Coastal wetlands play an important role in mitigating coastal hazards. Vegetation exerts a drag force to the flow and dampens storm surges and wind waves…. As wave height increases, highly flexible vegetation causes reduced wave attenuation, whereas relatively rigid vegetation induces increased wave attenuation. The leaf contribution to wave attenuation is highly dependent on the leaf rigidity. It is recommended that leaf properties, especially its Young’s modulus be collected in future field experiments.” Read the paper and see the full list of authors in Coastal Engineering.
