Uncovering the key bilateral trade linkages in the U.S. domestic food supply chain through disruption simulations

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This paper uses counterfactual simulations to examine the impact of bilateral trade linkage disruptions on the U.S. agricultural and food trade system. Using an econometric gravity model, we estimate the relationship between disruptions and trade flows, identify critical state‐to‐state trade linkages whose disruption would significantly impact

The Non‐Professional Virtues of the Hospice Volunteer

Journal of Applied Philosophy, EarlyView.
ABSTRACT Volunteers have long played a significant role in hospice care. Much of the care volunteers provide consists of weekly hour‐long in‐home visits. Home‐visiting hospice volunteers are not professionals, nor are they strangers or intimates. Hospice volunteers will not typically face moral dilemmas, nor be called upon to make dramatic decisions ...

Spatial As Deep: Spatial CNN for Traffic Scene Understanding

, 2017
Convolutional neural networks (CNNs) are usually built by stacking convolutional operations layer-by-layer. Although CNN has shown strong capability to extract semantics from raw pixels, its capacity to capture spatial relationships of pixels across rows

Turning the Tables: Leveraging Purpose as a Strategic Advantage for SMEs

Strategic Change, EarlyView.
ABSTRACT When executed well, purpose can become a transformative force, turning a business into a breakout success. Despite the wave of purpose‐driven businesses in recent years, the concept of purpose remains underdeveloped. Purpose is a core component of business models but is difficult to retrofit into large corporations, which makes it especially ...

Optimizing Coordinated Vehicle Platooning: An Analytical Approach Based on Stochastic Dynamic Programming

, 2020
Platooning connected and autonomous vehicles (CAVs) can improve traffic and fuel efficiency. However, scalable platooning operations require junction-level coordination, which has not been well studied. In this paper, we study the coordination of vehicle

Anti-rollover Artificial Potential Field Motion Planning Method of an Autonomous Heavy Truck Optimised by Game Theory

Chinese Journal of Mechanical Engineering
Anti-rollover is a critical factor to consider when planning the motion of autonomous heavy trucks. This paper proposed a method for autonomous heavy trucks to generate a path that avoids collisions and minimizes rollover risk. The corresponding rollover

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting
