Summary: Competition among analysts for forecast accuracy can have varying effects on forecast informativeness. If prior uncertainty of the economic state is high and analysts' private signals are positively correlated, competition may impair informativeness. The intensity of competition and the number of competing analysts are important factors influencing the informativeness of forecasts.

Summary: This study investigates the potential of connected and automated vehicles (CAVs) and infrastructure-to-vehicle (I2V) communication to improve traffic safety and mobility at both intersection and road segment levels. The impact of en-route locational information updates on system-level safety and mobility is studied using a two-stage stochastic traffic equilibrium model. Real traffic and accident data from the Orlando transportation network are used to test the proposed methodology. Different I2V information sharing strategies are analyzed to gain insights on the optimal design of traffic information sharing systems.

Summary: Cyberchondria refers to excessive online searches for medical information, often accompanied by emotional distress or anxiety. This study proposes a theoretical framework to explain why cyberchondria develops when seeking medical information from different online sources. Findings from a panel survey suggest that using online search engines for health information increases online information overload, while seeking health information from social media platforms and health-specific websites increases online information trust. Both online information overload and online information trust are related to the development of cyberchondria.

Summary: Drawing on the resource-based view, this study examines the impact of big data use on firm legitimacy. Using panel data from Chinese firms over the period 2012-2019 and employing Tobit instrumental variable regression, the results show a positive association between big data utilization and firm legitimacy, with an increase of one point in big data utilization leading to a 27.4% increase in firm legitimacy. This effect is stronger for firms operating in highly competitive industries. Overall, this study contributes to the emerging literature on big data and provides insights on how firms can leverage data-driven insights to manage their organizational environment.

Summary: This paper proposes an innovative operational framework for strategic online en-route operations, capturing the interactions of traffic flow and strategic conflict managements in a more harmonized way. The framework includes a traffic situation awareness method based on digital airspace and a trajectory selection model. Numerical experiments show that integrating traffic flow and strategic conflict managements significantly improves airspace capacity utilization and reduces the number of trajectory conflicts. This method provides a new reference for developing operational frameworks in high-density en-route airspace.

Summary: This paper examines the impact of online interactions between retail investors and firm management on financial leverage using a sample of Chinese A-share listed companies from 2010 to 2021. The findings show that retail investors' interaction with management significantly decreases firms' financial leverage by reducing information asymmetry. Moreover, the negative relationship is stronger for firms with more opaque information environments, indicating the importance of information disclosure reform in emerging capital markets.

Summary: Advancements in technology have had a significant impact on road safety and communication. However, the emergence of Facebook police location pages and groups raises concerns about the potential for illegal and dangerous driving behaviors to go unpunished. This study examined two Facebook police location groups and three pages from Queensland, Australia, and found that some users had personal experiences of evading punishment for drug driving and lacked knowledge about safe time intervals between drug consumption and driving. The findings highlight the need for greater responsibility from Facebook and the government to address these issues.

Summary: This article reinvestigates the mathematical formulations of traffic assignment problems with perception stochasticity and demand elasticity, proposing a pair of dual general formulations. The equilibrium or optimality conditions of these problems can be redefined as a combination of equations, and the solutions of the primal and dual formulations have been proven to be equivalent and unique. Algorithmic analysis and numerical tests suggest that the dual formulation-based algorithm, the Cauchy algorithm, is more suitable for large-scale problems and converges faster than the primal formulation-based Frank-Wolfe algorithm.

Summary: Mobility-as-a-Service (MaaS) is an emerging business model that integrates various travel modes into a single on-demand mobility service. This study proposes a MaaS ecosystem that provides both mobility and instant delivery services by sharing the same multimodal transport system. A bilaterial surcharge-reward scheme (BSRS) is introduced to manage the integrated mobility and delivery demand, and a solution algorithm is developed to optimize the system equilibrium costs.

Summary: This paper proposes a generalized multi-modal multi-provider market equilibrium model to evaluate the operation of transport systems. The model includes various modes of transportation such as private vehicles, walking, public transport, ride-sourcing, and ridesharing. The economic behaviors of service providers and a network operator are modeled using optimization problems and user equilibrium conditions, forming a complementarity formulation for the market at equilibrium. Extensive computational experiments demonstrate the model's applicability in handling various market responses to technological improvements, demand changes, emissions restrictions, and cultural barriers.

Summary: This paper presents a novel multi-objective mixed integer linear programming model that considers the selection of suitable suppliers, inventory management practices, and order quantities to optimize the trade-off between procurement cost and material delay impacts. The proposed model treats material prices, supplier capacities, and delays as fuzzy scenario-based parameters and is validated through numerical testing. The sensitivity analysis shows the importance of accurate estimation for uncertain parameters. The paper also demonstrates the higher performance of the proposed model compared to deterministic market conditions.

Summary: This study examines the theoretical connections between off-site construction (OSC) and lean, and investigates the impact of OSC strategies on flow, completion times, and simplification in construction. The findings show that OSC can significantly reduce schedule durations and minimize the number of parts on-site, but flow variability remains unchanged compared to traditional construction. This study contributes to the existing knowledge by quantifying the impact of OSC strategies on flow and empirically examining their benefits from a simplification perspective.

Summary: In the context of Mobility-as-a-Service (MaaS), the transportation sector is shifting towards user-centric business models that prioritize user experience and customized mobility solutions. This study proposes an auction-based mechanism and optimization models for the demand-side management of MaaS systems. The mechanism allows users to bid for mobility services based on their willingness to pay and experience-related preferences, and the optimization models aim to maximize social welfare by optimally allocating mobility resources in real-time. Extensive simulations using realistic mobility data demonstrate the benefits of the proposed mechanism.
