      Detailing the opportunities and challenges of omnichannel business, this paper serves as an editorial note to the corresponding special issue. We advance a framework that delineates extant literature on omnichannel business into four predominant research streams according to their perspective (i.e., consumer versus retailer) and research orientation (i.e., diagnostic versus prescriptive). For each of the four research streams, we articulate its current state of research and describe how select articles assembled in this special issue enhance the stream.

  • Mindfully going omni-channel: An economic decision model for evaluating
           omni-channel strategies

      In the digital age, customers want to define on their own how to interact with organizations during their customer journeys. Thus, many organizations struggle to implement an omni-channel strategy (OCS) that meets their customers' channel preferences and can be operated efficiently. Despite this high practical need, research on omni-channel management predominantly takes a descriptive perspective. What is missing is prescriptive knowledge that guides organizations in the valuation and selection of an appropriate OCS. Most existing studies investigate single facets of omni-channel management in detail while neglecting the big picture. They also require customer journeys to follow sequential and organization-defined purchase decision processes. To address this research gap, we propose an economic decision model that considers online and offline channels, the opening and closing of channels, non-sequential customer journeys, and customers' channel preferences. Drawing from the principles of value-based management, the decision model recommends choosing the OCS with the highest contribution to an organization's long-term firm value. We applied and validated the decision model based on real-world data from a German bank.

      The purpose of this study was to develop a model of factors associated with healthcare data breaches. Variables were operationalized as the healthcare facilities' level of exposure, level of security, and organizational factors. The outcome variable was the binary value for data breach/no data breach. Because healthcare data breaches carry the risk of personal health information exposure, corruption or destruction, this study is important to the healthcare field. Data were obtained from the Department of Health and Human Services database of healthcare facilities reporting data breaches and from a large national database of technical and organizational infrastructure information. Binary logistic regression was utilized to examine a representative data breach model. Results indicate several exposure, security and organizational factors significantly associated with healthcare data breaches.

      The purpose of this study is to investigate the impact of flow and psychological ownership on security education, training, and awareness (SETA) effectiveness, self-efficacy, and security compliance intention. The important role of experiencing flow in SETA is presented as focal antecedents of psychological ownership, self-efficacy, SETA effectiveness, and security compliance intention. To achieve these goals, we propose a theoretical framework and analyze survey data to test the hypotheses. Flow components in SETA are extended to include challenge, feedback, autonomy, immersion, and social interaction. The results illustrate that experiencing flow in SETA shows significant relationships with SETA effectiveness and psychological ownership, which in turn positively influence security compliance intention. Appropriate theoretical contributions and managerial implications are also discussed.

      This paper investigates the factors that influence the adoption of IT platforms by software developers and how those factors differ from those that influence IT adoption by end-users. We take a multi-methodological approach, beginning with an interpretive field study where we interview mobile application developers. In the initial interpretive phase, we identify a comprehensive set of influences on developers' platform adoption, comparing them with the factors that have been identified in previous studies of end-user adoption, noting key differences. In the second phase, we empirically test the factors identified in our interviews. We find several key differences between end-user adoption of IT and developer adoption of IT platforms. Most notably, we observe the importance of network externality considerations when developers make an adoption decision, a consideration that is largely absent for end-users. Our study is among the first to comment on B2B and B2C issues in the adoption phenomenon where developers adopt a platform as technology producers (a B2B consideration) in order to ultimately provide mobile applications to end-users who are technology consumers (a B2C consideration).

  • Can irrelevant benchmark information help when making business decisions
           under uncertainty' An empirical investigation of the newsvendor game

      Firms often compensate employees based on their relative performance in the most recent business period. These firms need to consider what type of performance information to share with their employees in order to obtain better outcomes in the long run, without diminishing staff motivation. In this paper, we empirically investigate the impact of sharing irrelevant benchmark “information” (e.g., information about the interim winner's performance) when individuals are making repeated decisions under uncertainty. The decision-making context used is the newsvendor problem, which is a canonical framework for operations management decision making. The newsvendor problem occurs in many business contexts, such as buying fashion goods for retail, setting safety stock levels, setting target inventory levels for perishable goods, selecting the right capacity for a service facility, and overbooking customers. Theoretically, information about the interim winner's performance has no value for making improved decisions in future rounds, and it might even be misleading. Surprisingly, we find that displaying such irrelevant benchmark information results in significantly improved decisions overall, as compared to a control group; this additional display may motivate participants to perform better. We also identify two personality traits related to impulsivity which moderate this positive information display effect.

  • Disentangling consumer recommendations: Explaining and predicting airline
           recommendations based on online reviews

      Consumer recommendations of products and services are important performance indicators for organizations to gain feedback on their offerings. Furthermore, they are important for prospective customers to learn from prior consumer experiences. In this study, we focus on user-generated content, in particular online reviews, to investigate which service aspects are evaluated by consumers and how these factors explain a consumer's recommendation. Further, we investigate how recommendations can be predicted automatically based on such user-driven responses. We disentangle the recommendation decision by performing explanatory and predictive analyses focusing on a sample of airline reviews. We identify core and augmented service aspects expressed in the online review. We then show that service aspect-specific sentiment indicators drive the decision to recommend an airline and that these factors can be incorporated in a predictive model using data mining techniques. We also find that the business model of an airline being reviewed, whether low cost or full service, is also an applicable consideration. Our results are highly relevant for practitioners to analyze and act on consumer feedback in a prompt manner, along with the ability of gaining a deeper understanding of the service from multiple aspects. Also, potential travelers can benefit from this approach by getting an aggregated view on service quality.

  • Failure pattern-based ensembles applied to bankruptcy forecasting
    • Authors: Philippe du Jardin
      Pages: 64 - 77

      Bankruptcy prediction models that rely on ensemble techniques have been studied in depth over the last 20 years. Within most studies that have been performed on this topic, it appears that any ensemble-based model often achieves better results than those estimated with a single model designed using the base classifier of the ensemble, but it is not uncommon that the results of the former model do not outperform those of a single model when estimated with any other classifier. Indeed, an ensemble of decision trees is almost always more accurate than a single tree but not necessarily more than a neural network or a support vector machine. We know that the accuracy of an ensemble used to forecast firm bankruptcy is closely related to its ability to capture the variety of bankruptcy situations. But the fact that it may not be more efficient than a single model suggests that current techniques used to handle such a variety are not completely satisfactory. This is why we have looked for a method that makes it possible to better embody this diversity than current ones do. The technique proposed in this article relies on the quantification, using Kohonen maps, of temporal patterns that characterized the financial health of a set of companies, and on the use of an ensemble of incremental size maps to make forecasts. The results show that such models lead to better predictions than those that can be achieved with traditional methods.

  • The interplay between emotion, cognition and information recall from

      Websites are increasingly used for information dissemination and web sites can include cues such as images that stimulate emotional responses in users and aid recall of information that can be utilized in decision making. However, these images may be more or less relevant in the context of the information provided. In such cases there is likely to be a complex interplay between users' emotional and cognitive responses and the degree of information recall. This study used event-related electroencephalography (EEG) to shed light on these inter-relationships. Images providing emotional cues influenced emotions and EEG responses and these responses were in turn related to the degree of information recall. Importantly, the study shows that the neural correlates of emotion vary depending on whether the emotion-inducing image is relevant to the information provided or not and that these correlates are significantly related to recall.

  • Investors' inertia behavior and their repeated decision-making in online
           reward-based crowdfunding market
    • Abstract: Publication date: Available online 1 June 2018
      Source:Decision Support Systems
      Author(s): Shengsheng Xiao, Qing Yue
      Extending recent work on individual-level decision in the emerged reward-based crowdfunding market, we formulated a Panel Vector Auto Regression Model with exogenous variables to examine whether investors' Inertia Behavior (IB) exists in their repeated investment decisions (i.e., which reward tier to select and when to invest). If so, how to quantify the effect of this behavior and how investors' heterogeneity moderates the effect of this behavior. We collected a novel and individual-level dataset from a leading crowdfunding market. Our analysis suggests the existence of investors' IB. Furthermore, we also found that (1) Investors' IB in reward tier selection seems to be stronger than that in investment timing selection. (2) Investors' platform tenure significantly accentuates their IB reward tier selection, but weakens that in investment timing selection. (3) Project attributes related factors have different impacts on investors' decision-making and peer investors' influence have stronger impact on backers' investment timing selection when compared with fundraisers' marketing efforts. Our results provide implications for crowdfunding participants including investors, fundraisers and the crowdfunding intermediaries hosting them.

  • Business value-aware task scheduling for hybrid IaaS cloud
    • Abstract: Publication date: Available online 1 June 2018

      Author(s): Helan Liang, Yanhua Du, Fanzhang Li
      Since an Infrastructure as a Service (IaaS) provider has limited resources, it faces the challenge of scheduling tasks to meet the peak demand. For this issue, the task scheduling problem for hybrid cloud from an IaaS provider's perspective should be properly addressed. However, existing research does not consider either process tasks with slack temporal constraints or the business value from an IaaS provider's perspective, or it has to specify the type of Virtual Machine (VM) for each task prior. In this paper, we first formalize the problem in which both process tasks with slack temporal constraints and VM type selection optimization are considered, and business value is taken as the objective to comprehensively measure the earned value of an IaaS provider. Second, a novel Evolutionary Algorithm for Task Scheduling in a Hybrid IaaS Cloud (EATSHC) is proposed to solve the problem. Finally, several experiments show our approach performs more effectively and efficiently than existing research.

      Ensemble learning can improve the performance of individual classifiers by combining their decisions. The sparseness of ensemble learning has attracted much attention in recent years. In this paper, a novel multiobjective sparse ensemble learning (MOSEL) model is proposed. Firstly, to describe the ensemble classifiers more precisely the detection error trade-off (DET) curve is taken into consideration. The sparsity ratio (sr) is treated as the third objective to be minimized, in addition to false positive rate (fpr) and false negative rate (fnr) minimization. The MOSEL turns out to be augmented DET (ADET) convex hull maximization problem. Secondly, several evolutionary multiobjective algorithms are exploited to find sparse ensemble classifiers with strong performance. The relationship between the sparsity and the performance of ensemble classifiers on the ADET space is explained. Thirdly, an adaptive MOSEL classifiers selection method is designed to select the most suitable ensemble classifiers for a given dataset. The proposed MOSEL method is applied to well-known MNIST datasets and a real-world remote sensing image change detection problem, and several datasets are used to test the performance of the method on this problem. Experimental results based on both MNIST datasets and remote sensing image change detection show that MOSEL performs significantly better than conventional ensemble learning methods.

      The adoption of IT-based performance measurement systems (PMS) has increased in recent times. The proliferation of business intelligence (BI) has significantly impacted performance measurement in organizations. In this paper a novel process-based framework is proposed to enable end-to-end analysis of technology driven PMS implementation in an organization. The framework has been used to study PMS implementation in a large manufacturing firm in India. The analysis of the case provides key lessons about successful planning, execution and adoption of a BI based PMS as well as identification of critical success factors (CSF) in the implementation of PMS, that would be of interest to organizations planning to implement a similar system.

      P2P online lending platforms provide services where individuals lend money to others without the involvement of traditional financial institutions. Due to its convenience, the platforms have gained in popularity. However, these platforms may suffer a significant loss if they cannot make good loan decisions based on default prediction results. In this paper, we aim to support the loan decision on P2P platforms based on meta-level phone usage data when the information asymmetry exists for mass borrowers. We extract variables from phone usage data, and use an empirical study to analyze the relationship between these variables and loan default. Then a default prediction method is conducted for P2P lending based on the AdaBoost algorithm. The data used in this study are from the generalized used mobile phones, which make the method applicable to a wide range of users. The empirical study shows that phone usage patterns, including telecommunication patterns, mobility patterns, and App usage patterns contain predictive capability of loan default. The experiments on prediction method demonstrate satisfying performance, which suggests the proposed method has favorable potential being implemented in real-world P2P lending platforms.

  • Disaster early warning and damage assessment analysis using social media

      Author(s): Desheng Wu, Yiwen Cui
      Societies are confronted with destructive natural disasters of increasing frequency. Social networks are playing an increasingly important role as early warning systems, aiding with rapid disaster assessment and post-disaster recovery. There is a need for both the public and disaster-relief agencies to better understand how social media can be utilized to assess and respond to natural disasters. However, existing research on the role of social media in society's response to natural disasters is neither holistic nor systematic. In this study, we conduct a hierarchical multiscale analysis based on multiple data resources, combining social media data, economic losses, and geo-information. We verify the role played by social media before, during, and after a natural disaster. We investigate whether the combination of social media and geo-location information can contribute to a more efficient early warning system and help with disaster assessment. This paper draws attention to the fact that during a disaster, citizens turn to social media and the majority of tweets contain information about the hurricane and/or its impact with negative sentiment. We demonstrate that the severity of damage in one area is positively correlated with the intensity of disaster-related activity. Meanwhile, the coastal areas and areas with close proximity to Hurricane center tend to suffer from higher losses during a disaster. Our findings explore the role played by social media from individuals in affected populations and how they respond to unfolding natural disasters. Results hold significance with regard to providing timely assistance for both official institutions and netizens.

      Telecommunication system providers offer many special number commodities, and all marketing staff sell the commodities and special number combinations according to their marketing experience; consequently, telecommunication retailers find it difficult to consider both user demands and profits in their marketing strategies. This study proposes a classification model integrating K-means Particle Swarm Optimization (KPSO) and C5.0. The particles' PSO only followed pbest and gbest when moving, resulting in the disadvantage that PSO may easily fall into a local optimal solution. First, clustering analysis is carried out using the KPSO clustering method. Second, classification rules for clustering results are formulated by the C5.0 classification method, and a classification model is established in order to achieve effective descriptions of the clustering rules. The methods proposed herein can help retailers find and utilize complementary tariff products for mobile numbers as the basis for future sales and procurement. This study also analyzes the best media for customers' mobile phone purchase methods and utilizes different groups of buyers of the omnichannel. The proposed model is also able to categorize new future tariffs and can further conceptualize the clustering results in the analysis of telecom tariffs and product mix. Finally, the results effectively assist the telecommunications retail industry when considering procurement, product projects, sales, and marketing solutions.

      Although omnichannel retailing has gained significant interest among academics and practitioners, the mechanisms through which customers react to Cross-Channel Integration (CCI) in omnichannel retailing remain unclear. To this end, this study builds on the Push-Pull-Mooring (PPM) framework to unpack the processes through which uncertainty, identity attractiveness, and switching costs of omnichannel retailers play pushing, pulling, and mooring roles in shaping customers' reaction to CCI. We further explore the moderating influence of showrooming in these relationships. Survey findings reveal that uncertainty, identity attractiveness, and switching costs of omnichannel retailers partially mediate the effect of CCI on customer retention while fully mediating the relationship between CCI and interest in alternatives. We also uncovered that customer showrooming strengthens the negative relationship between CCI and retailer uncertainty. We conclude this paper with theoretical and practical implications of our findings.

      In the literature, researchers and practitioners can find a manifold of algorithms to perform a classification task. The similarity classifier is one of the more recently suggested classification algorithms. In this paper, we suggest a novel similarity classifier with multiple ideal vectors per class that are generated with k-means clustering in combination with the jump method. Two approaches for pre-processing, via simple standardization and via principal component analysis in combination with the MAP test and Parallel Analysis, are presented. On the artificial data sets, the novel classifier with standardization and with transformation power Y = 1 for the jump method results in significantly higher mean classification accuracies than the standard classifier. The results of the artificial data sets demonstrate that in contrast to the standard similarity classifier, the novel approach has the ability to cope with more complex data structures. For the real-world credit data sets, the novel similarity classifier with standardization and Y = 1 achieves competitive results or even outperforms the k-nearest neighbour classifier, the Naive Bayes algorithm, decision trees, random forests and the standard similarity classifier.

  • How self-service technology experience evaluation affects waiting time and
           customer satisfaction' A moderated mediation model
    • Abstract: Publication date: Available online 23 April 2018
      Source:Decision Support Systems
      Author(s): Souad Djelassi, Mbaye Fall Diallo, Stephan Zielke
      The effects of increasingly ubiquitous self-service technologies (SSTs) on customer satisfaction are ambivalent and poorly understood. In the retail sector, such technologies often provide decision support as main purpose (information terminals) or side effect (self-scanning). This research investigates how SST experience evaluation affects customer satisfaction with the store indirectly, through the mediation of waiting time satisfaction and satisfaction with SSTs, as well as whether the SST type moderates these processes. Satisfaction with SSTs strongly mediates the effect of SST experience evaluation on store satisfaction; both cognitive and affective waiting time satisfaction also mediate the relationship between SST experience evaluation and satisfaction with SSTs. These effects differ across SST types: The mediation of satisfaction with SSTs on the SST experience evaluation–store satisfaction link is stronger for less interactive technologies (self-checkout), whereas the mediating influence of affective waiting time satisfaction on the SST experience evaluation–satisfaction with SSTs relationship is stronger for more interactive technologies with supplementary decision support functions (self-scanning). If retailers or service providers aim to strengthen the link between SST experience and SST satisfaction via perceived waiting time, they should therefore consider to increase interactivity of SSTs by integrating interactive decision support functions (even if decision support is not the main purpose of the SST).

      The development of new data analytical methods remains a crucial factor in the combat against insurance fraud. Methods rooted in the research field of anomaly detection are considered as promising candidates for this purpose. Commonly, a fraud data set contains both numeric and nominal attributes, where, due to the ease of expressiveness, the latter often encodes valuable expert knowledge. For this reason, an anomaly detection method should be able to handle a mixture of different data types, returning an anomaly score meaningful in the context of the business application. We propose the iForestCAD approach that computes conditional anomaly scores, useful for fraud detection. More specifically, anomaly detection is performed conditionally on well-defined data partitions that are created on the basis of selected numeric attributes and distinct combinations of values of selected nominal attributes. In this way, the resulting anomaly scores are computed with respect to a reference group of interest, thus representing a meaningful score for domain experts. Given that anomaly detection is performed conditionally, this approach allows detecting anomalies that would otherwise remain undiscovered in unconditional anomaly detection. Moreover, we present a case study in which we demonstrate the usefulness of our proposed approach on real-world workers' compensation claims received from a large European insurance organization. As a result, the iForestCAD approach is greatly accepted by domain experts for its effective detection of fraudulent claims.

      Can language usage help determine which model approach is best suited to provide decision makers with desired insights' This research addresses that question through an investigation of Linguistic Inquiry and Word Count (LIWC), which calculates the presence of >80 language dimensions in text samples, and permits construction of custom dictionaries. This article demonstrates use of LIWC to ensure better problem/model fit within the context of selecting a decision support tool. We selected two simulation tools as research instruments to investigate a broader question on the usefulness of LIWC to guide choice of DSS tool. The tools selected were System Dynamics (SD) and Discrete Event Simulation (DES). First, we tested LIWC to analyze practitioners' language use when developing models. LIWC pointed out significant linguistic differences consistent with prior theoretical work, based on model development approach in a number of dimensions. These differences provided a basis for developing a custom dictionary for use on the second part of our study. The second part of the study focused on language used by decision makers in problem statements and used the linguistic clues identified in the first part of the study to ensure problem/model fit. Results indicated problem statements contained linguistic clues related to the type of information desired by problem solvers. The article concludes with a discussion about how LIWC and similar tools can help determine which DSS tools are suited to particular applications.

      We present a probability-based metric for semantic consistency using a set of uncertain rules. As opposed to existing metrics for semantic consistency, our metric allows to consider rules that are expected to be fulfilled with specific probabilities. The resulting metric values represent the probability that the assessed dataset is free of internal contradictions with regard to the uncertain rules and thus have a clear interpretation. The theoretical basis for determining the metric values are statistical tests and the concept of the p-value, allowing the interpretation of the metric value as a probability. We demonstrate the practical applicability and effectiveness of the metric in a real-world setting by analyzing a customer dataset of an insurance company. Here, the metric was applied to identify semantic consistency problems in the data and to support decision-making, for instance, when offering individual products to customers.

      The Hospital Readmissions Reduction Program (HRRP) established by the Centers for Medicare & Medicaid Services (CMS) penalizes hospitals that have excessive readmission rates. Research is needed to determine if there are factors that influence readmission penalties but may be out of the control of hospitals. In this study, we compare a set of geo-demographic, hospital, and quality of care characteristics of hospitals penalized by HRRP with those not penalized, and determine these characteristics' association with the likelihood of penalization as well as the extent of penalties. We collected and integrated data from multiple sources such as the HRRP Supplemental Data File, the Hospital Compare database, CMS Impact files, the HCAHPS survey, and the U.S. census. We followed a two-step estimation procedure. First, we estimated a logistic regression model to find the relationship between various characteristics and whether a hospital was penalized. Second, we estimated a linear regression model to find the relationship between these characteristics and the extent of penalties. Results show that both the likelihood and the extent of penalties varied across several characteristics related to geo-demographics (such as location in the census division, urban vs. rural location, and racial make-up of the area), hospitals (such as ownership, bed capacity, teaching status, and case mix index), and quality of care (such as quality of communication by doctors and information provided at the time of discharge). Although quality of care characteristics are under hospitals' control and can be improved, geo-demographic and hospital characteristics are likely consistent over time and largely out of the control of hospitals. The study supports the case for a comprehensive revision of HRRP's scoring methodology to calculate readmission penalties.

      With the development of mobile technology, spatial crowdsourcing has become a popular approach in collecting data or road information. However, as the number of spatial crowdsourcing tasks becomes increasingly large, the accurate and rapid allocation of tasks to suitable workers has become a major challenge in managing spatial outsourcing. Existing studies have explored the task allocation algorithms with the aim of guaranteeing quality information from workers. However, studies focusing on the task allocation rate when allocating tasks are still lacking despite the increasing unallocated rates of spatial crowdsourcing tasks in the real world. Although the task package is a commonly known scheme used to allocate tasks, it has not been applied to allocate spatial crowdsourcing tasks. To fill these gaps in the literature, we propose a real-time, budget-aware task package allocation for spatial crowdsourcing (RB-TPSC) with the dual objectives of improving the task allocation rate and maximizing the expected quality of results from workers under limited budgets. The proposed RB-TPSC enables spatial crowdsourcing task requester to automatically make key task allocation decisions on the following: (1) to whom should the task be allocated, (2) how much should the reward be for the task, and (3) whether and how the task is packaged with other tasks.

      This paper describes TaxNet, a decision support system for tax evasion discovery, based on a powerful visual language and on advanced network visualization techniques. It has been developed in cooperation with the Italian Revenue Agency, where it is currently used. TaxNet allows users to visually define classes of suspicious patterns, it exploits effective graph pattern matching technologies to rapidly extract subgraphs that correspond to one or more patterns, it provides facilities to conveniently merge the results, and it implements new ad-hoc centrality indexes to rank taxpayers based on their fiscal risk. Moreover, it offers a visual interface to analyze and interact with those networks that match a desired pattern. The paper discusses the results of an experimental study and some use cases conducted with expert officers on real data and in a real working environment. The experiments give evidence of the effectiveness of our system.

      Author(s): Min Chen
      It is well known that website success relies heavily on its usability. Previous studies find that website usability depends greatly upon its visual complexity which has significant effects on users' psychological perception and cognitive load. In this study, we use a page's outdegree as one measurement for its visual complexity. In general, outdegrees should be kept not too high in page design as large outdegrees are often signs of high page complexity which can adversely affect user navigation. This is particularly desirable and critical for maintaining website structures, because as a website evolves over time, the need for information also changes. Website structures must be updated periodically to align with users' information needs. In this process, obsolete links should be removed to avoid clustering of links that could cause information overload to users. However, the need to slim down website structures is understudied in the literature. In this paper, we propose a mathematical programming model that reduces information load by removing links from highly clustered pages while minimizing the impact to users. Results from tests on a real dataset indicate that the model not only significantly reduces page complexity with little impact on user navigation, but also can be solved effectively. The model is also tested on large synthetic datasets to demonstrate its remarkable scalability.

      Author(s): Mercedes Boncompte
      This paper reflects on the concept of the “expected value of perfect information” (EVPI) and the procedure used to determine it. It is widely accepted that this value is the difference between the expected value when we have perfect information and the best expected value provided by alternatives. However, this difference often results in values that no rational decision-maker would accept. Here, we overcome this difficulty by defining the “value of perfect information for the problem” (VPIP) where we consider not only the price of perfect information (EVPI) but also two additional parameters: the “loss to be avoided” and “the most favourable payoff in the worst scenario”. In this way, we are able to obtain a more accurate value of the amount a decision-maker might be willing to pay for perfect information. We also seek to show that the indiscriminate employment of probability theory, based by definition on the repetition of the experiment, can be misleading in the case of decisions which, owing to the very nature of the problem, are unrepeatable.

      To assist consumers in product search and selection while shopping online, many e-commerce retailers have implemented web-based product recommendation agents (PRAs). However, consumers are empowered to the extent that the PRAs provide true personalization by recommending products based solely on, and thus best representing, consumers' preferences. This study constructs and empirically tests a theoretical model that examines how biased recommendations from PRAs influence consumers' decision quality and decision effort. The results of an online experiment show that consumers are extremely vulnerable to biased personalized recommendations from online PRAs. In addition, our results extend prior research by identifying perceived personalization as a critical mechanism driving the influence of biased PRA on consumers' decision quality and decision effort. This study fills a void in the literature and calls attention to an insidious form of manipulation made possible by innovative technologies supporting e-commerce.

      A substantial portion of internet usage today involves social media applications. Aside from personal use, given the vast amount of content stored, and rapid diffusion of information, in social media, businesses have begun exploiting social media for competitive advantage. Its popularity has led to the recognition of Social Media Analytics (SMA) as a distinct, albeit formative, sub-field within the Analytics field. Against this backdrop, we examine available characterizations of SMA that collectively identify various considerations of interest. However, their diversity suggests the need for adopting a concise, unifying SMA definition. We present a definition that subsumes salient aspects of existing characterizations and incorporates novel features of interest to Business SMA. Further, we examine available conceptual frameworks for Business SMA and advance a framework that comprehensively models the Business SMA phenomenon. We also conduct a survey of recently published SMA research in the premier, academic Management Information Systems journals and use some of the surveyed papers to validate our framework.

      In the United States, approximately 4000 fatalities due to truck and bus crashes occur each year. Of these, up to 20% are estimated to involve fatigued drivers [48]. However, no model currently exists that incorporates a measure of drowsiness or fatigue into the Truck Driver Scheduling Problem (TDSP). We introduce a fatigue-aware model for determining the optimal schedule for a driver while maintaining an acceptable level of alertness as well as abiding by time windows and hours of service (HOS) regulations. Additionally, we examine a shortcoming in existing regulations, specifically related to assumptions made about the rest and alertness of a driver at the start of the workweek.

      Shoplifting is the largest contributor to inventory depletion in the US retail sector. To effectively mitigate and prevent such criminal activity, one needs to understand the shoplifter's perspectives on the suitability of the retail products targeted for shoplifting. Extending Routine Activity Theory (RAT) from criminology literature to include usefulness of online information, we analyze shoplifters' perceptions regarding future target suitability by considering a retail item's value, inertia, visibility, and accessibility (VIVA). We also examine how online information about a target's disposal and guardianship can influence shoplifters' decisions. In this paper, the Partial Least Squares (PLS) method was used to analyze data collected in the Western New York area over a one-year period. The results show positive effects of value and reverse inertia on target suitability. Interestingly, the relationship between target suitability and the usefulness of online information about post-shoplifting disposal activity was negative. Implications for future research and practical applications for shoplifting prevention are discussed.

      With the rapid development of e-commerce, a new type of secondhand e-commerce website has appeared in recent years. Any user can have his or her own shop and list superfluous items for sale online without much supervision. These secondhand e-commerce platforms maximize the economic value of secondhand markets online, but buyers risk conducting unpleasant transactions with low-reputation sellers. The main contribution of our research is the design of a text analytics framework to assess secondhand sellers' reputation. In addition, we develop a new aspect-extraction method that combines the results of domain ontology and topic modeling to extract topical features from product descriptions. We conduct our experiments based on a real-word dataset crawled from XianYu. The experimental results reveal that our ontology-based topic model method outperforms a traditional topic model method. Furthermore, the proposed framework performs well in different item categories. The managerial implication of our research is that potential buyers can prejudge the reputation of secondhand sellers when making purchase decisions. The results can support a more effective development of online secondhand markets.

      Recommendation systems make use of complex algorithms and methods to provide recommendations to consumers. Typically, online rating schemes use a single rating metric that captures the overall user experience with a product. Nevertheless, this might hinder the intricacies of how a product's attributes influence an individual's preferences. While it is possible to use sentiment and semantic analysis to interpret free text in user reviews, if available, to gain insight into a user's reasons for a product rating, these methods are expensive to implement and error prone, and rely on significant data input from the user. To overcome these challenges, we propose a method for inferring user preferences and generating recommendations without relying on the availability or quality of text reviews. Specifically, our method is designed to use existing product metadata and user rating patterns to shed light on how the attributes of a product correspond to individual preferences. Our method uses only the user's history of ratings and the corresponding product attributes to generate predicted ratings for products a user has not yet experienced. This work extends existing work in this area by focusing on multi-valued attributes, and considering the distinct impact of each attribute value in a user's preferences. In terms of computational complexity, our method runs in linear time, making it feasible for real-time implementations. Our experimental results showed that, compared with the two best-performing existing state of the art methods, our method provided review score predictions with up to: 47.7% greater precision, 6.9% greater recall, and 20.5% greater F-measure than existing methods.

      Online reviews provide information about products and services valuable for consumers in the context of purchase decision making. Online reviews also provide additional value to online retailers, as they attract consumers. Therefore, identifying the most-helpful reviews is an important task for online retailers. This research addresses the problem of predicting the helpfulness of online product reviews by developing a comprehensive research model guided by the theoretical foundations of signaling theory. Thereby, our research model posits that the reviewer of a product sends signals to potential buyers. Using a sample of product reviews, we test our model and observe that review content-related signals (i.e., specific review content and writing styles) and reviewer-related signals (i.e., reviewer expertise and non-anonymity) both influence review helpfulness. Furthermore, we find that the signaling environment affects the signal impact and that incentives provided to reviewers influence the signals sent. To demonstrate the practical relevance of our results, we illustrate by means of a problem-specific evaluation scenario that our model provides superior predictions of review helpfulness compared to earlier approaches. Furthermore, we provide evidence that the proposed evaluation scenario provides deeper insights than classical performance metrics. Our findings are highly relevant for online retailers seeking to reduce information overload and consumers' search costs as well as for reviewers contributing online product reviews.

      The productivity of a maritime container terminal can be improved through a model-driven decision support system (DSS) focused on a better integration among container handling operations occurring across the quay, transfer and yard areas. Integration is pursued to minimize the blocking, locking and other queuing phenomena which are unavoidable, especially when human-operated equipment is shared in a real environment subjected to several random events and activities. An integrated queuing network is proposed in this paper as the natural modeling paradigm for a DSS aimed to highlight and quantify the blocking, locking and other queuing phenomena experienced in real practice. After an in-depth discussion of the limitations of solving the queuing network model analytically, discrete-event simulation is adopted as solution method. Numerical examples referred to a case study for a real transshipment hub return reliable estimates for the above queuing phenomena. They illustrate how the queuing-based DSS may effectively support the operations manager in determining the proper operational policies and equipment management with respect to a proficient integration of container handling operations.

      Research has shown that preexisting individual biases about a product can have negative effects on future purchase behavior or use. While extensively studied in marketing, the role of informational blocking with regard to decision making about information technologies has not been investigated. This research explores the interplay of biases as a form of information blocking and explores these biased-blocking effects in the context of technology. Results show that while different types of experience have a significant effect on the decision to use a technology product, this effect is completely blocked by the preconceived bias of the individual about the technology.

      This study predicts tax avoidance by means of social network analytics. We extend previous literature by being the first to build a predictive model including a larger variation of network features. We construct a network of firms connected through shared board membership. Then, we apply three analytical techniques, logistic regression, decision trees, and random forests; to create five models using either firm characteristics, network characteristics or different combinations of both. A random forest including firm characteristics, network characteristics of firms and network characteristics of board members provides the best performance with a minimal increase of 7 pp in AUC. Hence, including network effects significantly improves the predictive ability of tax avoidance models, implying that board members exhibit specific knowledge which can carry over across firms. We find that having board members with no connections to low-tax companies lowers the likelihood of being a low-tax firm. Similarly, the higher the average tax rate of the companies a board member is connected to, the lower the chance of being low-tax. On the other hand, being connected to more low-tax firms increases the probability of being low-tax. Consistent with prior literature on firm-specific variables, PP&E has a positive influence on the probability of being low-tax, while EBITDA has a negative effect. Our results are informative for companies as to the director expertise they want to attract in their boards. Additionally, financial analysts and regulatory agencies can use our insights to predict which firms are likely to be low-tax and potentially at risk.

      Digitalization is fundamentally changing the retailing ecosystem for shopping malls as digital and analogue elements get increasingly intertwined. We conceptualize shopping malls as two-sided markets whose primary function is connecting shoppers and retailers. By means of an interpretative case study, the article then presents an omnichannel strategy typology for how shopping malls can meet the evolving digitalization challenge. We identify three generic strategies labeled digital awaiter, digital data gatherer, and digital embracer. The paper provides implications for research in omnichannel strategies, digitalization, and two-sided markets by explicating different strategies that involve physical and digital resources, and different ecosystem agents, i.e., retailers and shoppers. It also provides insights for other organizations beyond retailing and which operate under a two-sided market regime.

  • Cannibalization and competition effects on a manufacturer's retail channel
           strategies: Implications on an omni-channel business model

      This paper analyzes two effects caused by “channel conflict”, which occurs when firms newly add a direct online channel via the Internet or a mobile device. The first is an “intra-cannibalization effect” between the firms' existing retail channel and the new online channel, and the second is the “inter-competition effect” between manufacturers and retailers in the supply chain. In particular, this paper investigates a manufacturer's retailing channel strategy considering the relative market power between a manufacturer and a retailer in the supply chain, which has been rarely considered in previous studies. This paper shows the manufacturer's channel strategies: (i) if customers are very heterogeneous with regard to their receptiveness to online shopping, the manufacturer may use a multi-channel strategy. (ii) if the customer sector becomes homogeneous, the manufacturer will become more willing to adopt an omni-channel strategy. (iii) if customers are neither similar nor very different, the manufacturer uses a brick-and-mortar strategy. This paper also shows results on the issue of channel conflict in terms of market power: (i) the retailer may voluntarily limit its market power and thus, self-created competition in the retail market alleviates the problem of double-markup to some extent. (ii) the manufacturer can use an online channel when inter-competition effect becomes severe.

      Along with the rapid development of in-store technology, multichannel service is being shifted to omnichannel. By integrating different parallel channels, omnichannel service delivers customers an integrated, seamless and consistent cross-channel shopping experience. To better understand this emerging phenomenon, this study intends to explore the potential drivers of omnichannel service usage. Drawing upon Wixom & Todd framework, this study develops a research model by including object-based beliefs (i.e., channel integration quality) and behavioral beliefs (i.e., perceived fluency). In addition, behavior-based traits (i.e., internal and external usage experience) are hypothesized as moderating the effects of behavioral beliefs on usage behavior. Using an online survey of 401 omnichannel users, the findings demonstrate that channel integration quality significantly affects perceived fluency across different channels, which in turn explains 55% of the variance in omnichannel service usage. The results also show that internal usage experience weakens, whereas external usage experience enhances the effect of perceived fluency on omnichannel service usage. Limitations and implications of this study are further discussed.

  • Omnichannel businesses in the publishing and retailing industries:
           Synergies and tensions between coexisting online and offline business

      Since the emergence of the Internet, many brick-and-mortar companies from various industries have established an online business model (BM) alongside their traditional offline BM. Despite the increasing coexistence of online and offline BMs within a single company, however, most prior research has focused on studying online and offline BMs in isolation. Consequently, still little is known about the interplay of dual BMs in omnichannel businesses. We address this research gap through an empirical investigation of the synergies and tensions that arise from coexisting online and offline BMs as well as the factors that influence the emergence of such synergies and tensions. Drawing on a series of six case studies with three publishers and three retailers, we identify an extended set of BM synergies and tensions, which concern all major BM dimensions. In addition, our case analysis reveals that companies are able to exploit different synergies, but also face different tensions between their online and offline BMs. The observed differences can be traced back to the level of online-offline BM integration, online-offline product distinctions (e.g., in terms of product content and publication cycles), and general organization context factors (e.g., offline brand strength, organization structure). By uncovering both the benefits and the complexity of running online and offline BMs in parallel, our study contributes to the theoretical understanding of omnichannel businesses, and provides managers with practical guidance on how to design, integrate, and manage their dual BMs successfully.

  • Augmenting processes with decision intelligence: Principles for integrated

      Until recently decisions were mostly modelled within the process. Such an approach was shown to impair the maintainability, scalability, and flexibility of both processes and decisions. Lately, literature is moving towards a separation of concerns between the process and decision model. Most notably, the introduction of the Decision Model and Notation (DMN) standard provides a suitable solution for filling the void of decision representation. This raises the question whether decisions and processes can easily be separated and consistently integrated. We introduce an integrated way of modelling the process, while providing a decision model which encompasses the process in its entirety, rather than focusing on local decision points only. Specifically, this paper contributes formal definitions for decision models and for the integration of processes and decisions. Additionally, inconsistencies between process and decision models are identified and we remedy those inconsistencies by establishing Five Principles for integrated Process and Decision Modelling (5PDM). The principles are subsequently illustrated and validated on a case of a Belgian accounting company.
