Striking a Balance: Harnessing Both the Business and Informational Value of Online Reviews through Resource-matching

A majority of consumers now are getting used to consulting reviews before making any purchase decisions. Although we have witnessed fruitful studies in this stream of literature, there lacks sufficient knowledge regarding whether and how we can realize the information and business values simultaneously. We undertook to bridge this gap. Drawn from the cognitive tuning theory and resource-matching theory, we posit that review sentiment would intertwine with the information richness of a review to affect consumers’ judgment of review helpfulness and purchase decision. Our empirical results demonstrate that the information richness of a review, overall, moderates the U-shaped relationship between review sentiment and review helpfulness, as well as the inverted U-shaped relationship between review sentiment and consumer purchase likelihood. These findings unravel certain conditions under which increasing both purchases and review helpfulness could be achieved, which, therefore, offer non-trivial insights into business practice about review-featuring designs

On the large time asymptotics of bi-laplacian Schr\"odinger equation with general data

We study the bi-laplacian Schr\"odinger equation with a general interaction term, which can be either linear or nonlinear, and is time-dependent. We prove that the global solutions for this equation are asymptotically given by a free wave and a weakly localized part. The proof relies on constructing the Free Channel Wave Operator in a new way, based on the method developed from recent studies \cite{SW20221}.Comment: 27 pages. Comments welcom

Brake or Step On the Gas? Empirical Analyses of Credit Effects on Individual Consumption

Understanding the effects of credit on consumption is crucial for guiding users’ consumption behavior, designing financial marketing strategies, and identifying credit\u27s value in stimulating the economy. Whereas several studies have endeavored on this issue, most simply utilize observations of a single credit channel and/or focus on an overall effect without considering the potentially heterogeneous short-term and long-term consumption changes. This study, leveraging a quasi-experimental design with high-resolution transaction data, examines how people respond to credit in both short- and long-term periods. Results show that credit users’ consumption amount significantly expand by 51.74% after getting access to credit in the short term. However, they ultimately cut their consumption by 4.02% to cope with financial constraints in the long term. We also reveal and quantify the spillover effects of credit on consumption with savings channels. We draw on regulatory focus theory to rationalize the changes on consumers’ consumption behavior after credit activation

Monomeric ephrinB2 binding induces allosteric changes in Nipah virus G that precede its full activation.

Nipah virus is an emergent paramyxovirus that causes deadly encephalitis and respiratory infections in humans. Two glycoproteins coordinate the infection of host cells, an attachment protein (G), which binds to cell surface receptors, and a fusion (F) protein, which carries out the process of virus-cell membrane fusion. The G protein binds to ephrin B2/3 receptors, inducing G conformational changes that trigger F protein refolding. Using an optical approach based on second harmonic generation, we show that monomeric and dimeric receptors activate distinct conformational changes in G. The monomeric receptor-induced changes are not detected by conformation-sensitive monoclonal antibodies or through electron microscopy analysis of G:ephrinB2 complexes. However, hydrogen/deuterium exchange experiments confirm the second harmonic generation observations and reveal allosteric changes in the G receptor binding and F-activating stalk domains, providing insights into the pathway of receptor-activated virus entry.Nipah virus causes encephalitis in humans. Here the authors use a multidisciplinary approach to study the binding of the viral attachment protein G to its host receptor ephrinB2 and show that monomeric and dimeric receptors activate distinct conformational changes in G and discuss implications for receptor-activated virus entry
