A growing number of studies in international relations use experiments. Roth (1995) discusses at least three purposes for experiments: (i) testing theoretically derived models, or ''speaking to theorists''; (ii) data generation, which he called ''searching for facts,''; and (iii) ''searching for...

As a key task of fine-grained sentiment analysis, aspect-based sentiment analysis aims to analyse people's opinions at the aspect level from user-generated texts. Various sub-tasks have been defined according to different scenarios, extracting aspect terms, opinion terms, and the corresponding...

Motivated by Fresh Hema, we consider a distribution system in which retailers replenish perishable goods from a warehouse, which, in turn, replenishes from an outside source. Demand at each retailer depends on exogenous features and a random shock, and unfulfilled demand is lost. The objective...

This paper explores how a strategic retailer (e.g., Best Buy) monetizes its showrooming service and its impact on brands' (e-tailers') competition and social welfare. We conduct an equilibrium analysis of duopoly brands in a horizontal market and a vertical market, and compare the results to...

We consider the classic continuous-review N-stage serial inventory system with a homogeneous Poisson demand arrival process at the most downstream stage (Stage 1). Any shipment to each stage, regardless of its size, incurs a positive fixed setup cost and takes a positive constant leadtime. The...

In this paper, we develop FinBERT, a state-of-the-art large language model that adapts to the finance domain. Using a sample of researcher-labeled sentences from analyst reports, we document that FinBERT significantly outperforms the Loughran and McDonald dictionary and other machine learning...

Nanocrystallization can significantly improve the strength and hardness of metallic materials, but usually sacrifice ductility due to low work hardening capability. Heterostructured materials are an emerging class of materials with superior performances, because of their outstanding work...

Self-propelled autonomous devices have great significance in energy, environment, and biomedical engineering, and thus vast achievements have been made in recent years. However, conventional propulsion often requires special chemicals or external energy, which restricts their practical...

A 7-year multisite field experiment was performed to assess the relative importance of climate, soil, and microbial properties in crop production in a wheat cropping system under contrasting fertilization management (i.e., continuous organic vs. chemical fertilization). The results showed that...

There are numerous evidence showing that consumers usually experience emotional dissonance (e.g. purchase regret) and anticipate it in consideration set formation process. Our paper investigates how anticipated regret affects consumers' consideration set formation and the relevant implications...
