    Abstract: This study views corporate venture capital (CVC) investment as a form of inter‐firm rivalry. Adopting a competitive dynamics perspective, we argue that when a focal corporate investor invests in an entrepreneurial venture, that investment sends important competitive signals to its rivals, thereby increasing their likelihood of initiating a matching response. We theorize how three factors characterizing such investment—the amount of funding, industry relatedness between the corporate investor and the entrepreneurial venture, and the reputation of the corporate investor—can influence rivals' awareness of competitive threat, their motivation to respond, and therefore their likelihood of launching a matching counterattack. Our results demonstrate substantial support for our theoretical model. Managerial Summary This study views CVC investment as a form of competitive interaction, arguing that when a corporate investor participates in an investment round, it sends a competitive signal to its rival, motivating the latter to respond by also investing in CVC. Because of this counteraction, the competitive advantages of firms' CVC strategies may be temporary as rivals catch up and nullify the benefits of a CVC initiative. Thus, when planning strategy, CVC managers need to take potential rival counteractions into account and carefully assess the competitive implications of their CVC strategy, perhaps by avoiding harmful counteractions through initiatives more subtle in execution and orientation, and thus “under the radar” of rivals.

    LPPS: A Distributed Cache Pushing Based K -Anonymity Location Privacy Preserving Scheme

    Abstract: Recent years have witnessed the rapid growth of location-based services (LBSs) for mobile social network applications. To enable location-based services, mobile users are required to report their location information to the LBS servers and receive answers of location-based queries. Location privacy leak happens when such servers are compromised, which has been a primary concern for information security. To address this issue, we propose the Location Privacy Preservation Scheme (LPPS) based on distributed cache pushing. Unlike existing solutions, LPPS deploys distributed cache proxies to cover users mostly visited locations and proactively push cache content to mobile users, which can reduce the risk of leaking users’ location information. The proposed LPPS includes three major process. First, we propose an algorithm to find the optimal deployment of proxies to cover popular locations. Second, we present cache strategies for location-based queries based on the Markov chain model and propose update and replacement strategies for cache content maintenance. Third, we introduce a privacy protection scheme which is proved to achieve k -anonymity guarantee for location-based services. Extensive experiments illustrate that the proposed LPPS achieves decent service coverage ratio and cache hit ratio with lower communication overhead compared to existing solutions.

    Empirical Investigation of an Equity Pairs Trading Strategy
    Institute for Operations Research and the Management Sciences (INFORMS) ; 2019

    Abstract: We show that an equity pairs trading strategy generates large and significant abnormal returns. We find that two components of the trading signal (i.e., short-term reversal and pairs momentum) have different dynamic and cross-sectional properties. The pairs momentum is largely explained by the one-month version of the industry momentum. Therefore, the pairs trading profits are largely explained by the short-term reversal and a version of the industry momentum. The online appendix is available at https://doi.org/10.1287/mnsc.2017.2825 . This paper was accepted by Lauren Cohen, finance.

    Location-Aware POI Recommendation for Indoor Space by Exploiting WiFi Logs

    Abstract: Indoor shopping trajectories provide us with a new approach to understanding user’s behaviour pattern in urban shopping mall, which can be derived from user-generated WiFi logs using indoor localization technology. In this paper, we propose a location-aware Point-of-Interest (POI) recommendation service in urban shopping mall that offers a user a set of indoor POIs by considering both personal interest and location preference. The POI recommendation service cannot only improve user’s shopping experience but also help the store owner better understand user’s shopping preference and intent. Specifically, the proposed method consists of two phases: offline modelling and online recommendation. The offline modelling phase is designed to learn user preference by mining his/her historical shopping trajectories. The online recommendation phase automatically produces top- k recommended POIs based on the learnt preference. To demonstrate the utility of our proposed approach, we have performed a comprehensive experiment evaluation on a real-world dataset collected by 468 users over 33 days. The experimental results show that the proposed recommendation service achieves much better recommendation performance than several existing benchmark methods.

    Hierarchical Brokering with Feedback Control Framework in Mobile Device-Centric Clouds

    Abstract: We propose a hierarchical brokering architecture (HiBA) and Mobile Multicloud Networking (MMCN) feedback control framework for mobile device-centric cloud (MDC2) computing. Exploiting the MMCN framework and RESTful web-based interconnection, each tier broker probes resource state of its federation for control and management. Real-time and seamless services were developed. Case studies including intrafederation energy-aware balancing based on fuzzy feedback control and higher tier load balancing are further demonstrated to show how HiBA with MMCN relieves the embedding of algorithms when developing services. Theoretical performance model and real-world experiments both show that an MDC2 based on HiBA features better quality in terms of resource availability and network latency if it federates devices with enough resources distributed in lower tier hierarchy. The proposed HiBA realizes a development platform for MDC2 computing which is a feasible solution to User-Centric Networks (UCNs).

    Spread and control of medical rumors in a social network: A generalized diffusion model with a highly asymmetric network structure
    Wiley ; 2023

    In: Production and Operations Management, Wiley
    Abstract: Medical rumors have become a threat to modern society. To study the spread and control of rumors, nonlinear differential equations modeling with the well‐mixed assumption is commonly used. However, this approach ignores the underlying network structure which plays an important role in information spreading. We establish a generalized differential equations model to study the spread and control of medical rumors in a highly asymmetric social network. In our model, each node represents a group of people and a “weighted” and “directed” network describes the communications between these nodes. This network can be generated from real‐world data by community detection algorithms. We provide methods to numerically calculate the final size of a rumor in each node and its derivatives with respect to each parameter. With these methods, if the government has resources to influence the parameters subject to certain constraints or cost functions, one can obtain the optimal resources allocation easily through nonlinear programming algorithms. We show that the implications on the government's resources allocation from the well‐mixed special case in the literature or conventional wisdom may become inapplicable in the general situation. Therefore, the underlying network should not be ignored. Because the final size of a medical rumor is not always the best measure of its damage, we extend our results to a wide class of objectives and show that different objectives result in very different implications. While the lack of a rule of thumb may sound negative, our flexible framework provides a powerful workhorse for interested parties to work out the details in their specific situations. Finally, we provide a sufficient condition for no outbreak of rumors. This condition can serve as a heuristic that a government with abundant resources can use to prevent the outbreak of rumors.
