The Effect of Content Depth and Deviation on Online Review Helpfulness: Evidence from
Double-Hurdle Model (2021)
Information and Management
Authors: Chaojing Wu, Feng Mai, & Xiaolin Li
This research examines the effect of content depth and deviation of online product reviews on the likelihood of being voted and helpfulness. Our analyses on reviews of three product categories show that reviews with more depth and less content deviation are rated more helpful. Further, the relationships are moderated by a number of factors, including the deviation of numerical rating, recency of the review, and the reputation of the reviewer. The research contributes to the literature by showing how the content of a review and the interaction of content and numerical ratings jointly create value for consumers.
A Survey Comparing Critical Path Method, Last Planner System, and Location-Based Techniques
Journal of Construction Engineering and Management
Authors: Hylton Olivieri, Olli Seppanen, Thais Alves, Natalie M. Scala, Vincent Schiavone, Min Liu, & Ariovaldo Denis Granja
This article compares and contrasts the use of Critical Path Method (CPM), Last Planner System (LPS), and Location-Based Techniques (LB) in the planning and control phases of project management (PM), and project production management (PPM). We analyze a survey of construction professionals in Brazil, China, Finland, and the United States to clarify industry benefits of each method and eliminate potential misunderstandings regarding method use. We find benefits related to critical path analysis and managing contracts using CPM and improved production control with LB and LPS. We conclude that the construction industry can benefit from aligning project scheduling methods with project needs.
The Effect of Online Reviews on Product Sales: A Joint Sentiment-Topic Analysis (2019)
Information and Management
Authors: Xiaolin Li, Chaojing Wu, & Feng Mai
This research examines the business impact of online reviews. It empirically investigates the influence of numerical and textual reviews on product sales performance. We use a Joint Sentiment-Topic model to extract the topics and associated sentiments in review texts. We further propose that numerical rating mediates the effects of textual sentiments. Findings not only contribute to the knowledge of how eWOM impacts product sales, but also illustrate how numerical rating and textual reviews interplay while shaping product sales. In practice, the findings help online vendors strategize business analytics operations by focusing on more relevant aspects that ultimately drive sales.
Eliminating the Weakest Link Approach in Army Unit Readiness (2018)
Authors: Natalie M. Scala & Paul L. Goethals
This study examines the United States Army’s readiness metrics, as outlined in AR-220-1, and proposes an improvement in the composite metric, in order to evaluate units with greater precision, flexibility, and robustness. Our desirability function approach measures readiness based upon a set of priorities, adapting for type of mission and unit. Accurate assessments of readiness are crucial, as the level of Army readiness drives federal funding, defense policy, and deployment decisions. AAM via INFORMS Green Option
A Value Model for Asset Tracking Technology to Support Naval Sea-based Resupply (2018)
Engineering Management Journal
Authors: Natalie M. Scala & Jennifer Pazour
Naval seabasing is a dense storage environment and requires specialized logistics to fulfill emergent requests for tailored resupply packages while at sea. We develop a value model to identify the preferred technology to track inventory assets while stored in this dense environment. Evaluated technologies include radio frequency identification, barcoding, internal positioning systems (IPS), and camera-aided technology. We conclude that IPS is the preferred asset tracking technology in the seabasing environment.
