abstract = {La littérature académique propose un large éventail de méthodes de gestion du changement visant à identifier et réduire les résistances liées aux projets TI. Alors qu'en psychologie et sociologie, l'originalité de la méthode de l'inoculation a su séduire chercheurs comme praticiens, celle-ci n'a été que peu testée dans le domaine des systèmes d'information. Elle postule que de la même manière qu'un individu peut être vacciné contre un virus, il peut également s'autoprémunir d'influences négatives en s'exposant aux arguments avancés par les détracteurs du projet. La réfutation, à cet effet, consiste à fournir des arguments à l'individu pour l'aider à soutenir son attitude et à être capable de rejeter d'autres contre-argumentations à venir. Cette recherche dévoile les résultats d'une recherche-action menée pendant 3 ans auprès d'une société de conseil au sein de laquelle l'implémentation d'un système d'aide à la décision a été associée à de forts comportements de résistance face auxquels la technique de l'inoculation a été expérimentée pour en limiter les effets. Les résultats tendent à confirmer la contribution de ladite méthode sur la préservation des attitudes positives des partisans avec un effet « boomerang » relatif sur les détracteurs.},

abstract = {Purpose: The objective is to know what the mediating effect of the category of consumer products on sales performance is.



Methodology: Data from 216 e-commerce platforms were used using the Search-Experience-Trust (SEC) categorization. Two t tests were used to confirm significant differences between product categories and regression analyzes were performed to test the hypotheses.



Results: The results show that the ease of evaluating products before consumption has two main effects in electronic commerce: 1) they increase web traffic and 2) they decrease their conversion rate. However, the results also show that the ease of evaluating a product category directly influences online sales per visitor, since the mediating effect of the conversion rate is only partial.



Implications: This study contributes in practice to be able to determine predictive models related to the supply and demand of retail products in electronic commerce and shows a way to segment consumers who depend on their perceptions of product categories.



Originality/Value: This research, unlike what is in the literature, contributes to the study of electronic commerce from the perspective of the company, and not from the perspective of the consumer, in the performance of sales and conversion rates.



Keywords: Category Management; Information Economics; E-commerce; Perceived product quality, Conversion rate.},

abstract = {Eco-innovations are increasingly manufactured and consumed across national borders. Although global outsourcing can be financially profitable, it is questionable whether consumers respond to eco-innovations manufactured in different countries in the same way. This article introduces the ecological country-of-manufacture (COM) concept, which reflects consumers' perception of a country's commitment to sustainable development policy and practices. Drawing on schema theory, the current research examines how consumer reactions to ?ecological (in)congruence??when the sustainability reputation of a COM is a (mis)match with product eco-friendliness levels?vary across product categories (Study 1a), consumption contexts (Study 1b), and national settings (Study 2). Consumers report more preferential evaluations when there is ecological incongruence for privately consumed products and ecological congruence for publicly consumed products. The results also demonstrate the differential moderating effects of socioeconomic development factors and cultural dimensions. In emerging markets with highly embedded, hierarchical, and high-harmony cultures, consumers require ecological congruence to justify their adoption decisions, whereas in developed markets with highly autonomous, egalitarian, and high-mastery cultures, consumers are more likely to adopt eco-innovations that are ecologically incongruent.},

abstract = {To maximize the impact of an advertisement campaign on social networks, the real-time bidding (RTB) systems aim at targeting the most influential users of this network. Influence maximization (IM) is a solution that addresses this issue by maximizing the coverage of the network with top-k influencers who maximize the diffusion of information. Associated with online advertising strategies at Web scale, RTB is faced with complex ad placement decisions in real time to deal with a high-speed stream of online users. To tackle this issue, IM strategies should be modified in order to integrate RTB constraints. While most traditional IM methods deal with static sets of top influencers, they hardly address the dynamic influence targeting issue by integrating short time decision, no interchange and stream's incompleteness. This paper proposes a real-time influence maximization approach which takes influence maximization decisions within a real-time bidding environment. A deep analysis of influence scores of users over several social networks is presented as well a strategy to guarantee the impact of an IM strategy in order to define the budget of an ad campaign. Finally, we offer a thorough experimental process to compare static versus dynamic IM solutions wrt. influence scores.},

We draw on the field of critical social theory to introduce the ?Logics,? a new framework to the IS discipline that reveals a performative relationship between collective framing, power, and affect. The Logics enable us to study buy-in by revealing the differing degrees of affective self-identification that underpin and color social practices, showing their inherently political nature. We exemplify the affective as well as social politics of buy-in with an account of Unity 3D, a market-leading game engine that underwent a major repositioning from ?fringe? to ?mainstream? markets, and discuss four poles of affective positioning with which to conceptualize technology buy-in. We conclude by highlighting the consequent need for greater political and ethical awareness about the framing of IS and by proposing a framework for conceptualizing actors' orientations toward and thus possible buy-in or resistance to technology framing.},

abstract = {An important and challenging research problem in web of things is how to select an appropriate composition of concrete services in a dynamic and unpredictable environment. The main goal of this article is to select from all possible compositions the optimal one without knowing a priori the users' quality of service (QoS) preferences. From a theoretical point of view, we give bounds on the problem search space. As the QoS user's preferences are unknown, we propose a vector-valued MDP approach for finding the optimal QoS-aware services composition. The algorithm alternatively solves MDP with dynamic programming and learns the preferences via direct queries to the user. An important feature of the proposed algorithm is that it is able to get the optimal composition and, at the same time, limits the number of interactions with the user. Experiments on a real-world large size dataset with more than 3500 web services show that our algorithm finds the optimal composite services with around 50 interactions with the user.},

abstract = {Classical databases represent the traditional RDBMS's and the most widely used RDBMS in the world of databases and information systems; they have been regarded as the best systems for managing data. Today with the growth of the applications and data consumers, and its openness to the general public, tradi- tional Databases are not able to meet the needs of a large number of applications, including OLAP data processing and Business Intelligence analysis; As a result, many variants of DBMS have emerged like: Column Store, In Memory and NOSQL Databases, that meet users' expectations well, and which are better adapted to cur- rent needs. As a result, the scope of classical databases has become increasingly restricted to handle OLTP models and other few models. To deal with this prob- lem, vertical fragmentation is the best way to effectively handle the OLAP model, but this technique fails to handle some analytical queries with low selectivity, pre- senting poor results in some cases. In this perspective, we propose a new vertical fragmentation design T-Plotter which makes it possible to deal effectively with the whole of analytical queries and improve the performance of RDBMSs to process the OLAP data models.},

abstract = {Eco-innovations are an effective way for companies to strategically align themselves with customers' growing environmental concerns. Despite their crucial role, scant research has focused on eco-innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco-innovation, its degree of innovativeness, level of eco-friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco-innovative product designs across various high-tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco-innovative attributes on consumers' perceptions of product eco-friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco-friendliness levels of eco-innovative attributes on consumer adoption intentions in the case of high-complexity products but not for low-complexity products, emphasizing the need to adopt different approaches when developing eco-innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco-innovative attributes on consumers' perceptions of trade-offs between environmental benefits and product functionality and on their intentions to adopt eco-innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research.},

adoption, utilization and success of BI systems has grown substantially over the past two decades. The literature

suggests that organizations have largely failed to capture the benefits of BI systems to their full extent and are

seeking ways to leverage value from the implemented systems. However, prior studies do not have any comprehensive study that discusses the issues and challenges related to adoption, utilization and success of BI

systems. In this study, using a systematic literature review, we present comprehensive knowledge about what has

been found in the domain of BI system adoption, utilization and success. A total of 111 peer-reviewed studies,

covering three categories - adoption, utilization and success - published between 2000 and 2019, were selected.

The findings present the research methods, underpinning theories and key factors employed to study BI system

adoption, utilization and success. In addition, the review identified the key issues related to BI adoption, utilization and success and highlighted the areas that have attracted more or less attention. This study also suggests

future directions for researchers and practitioners in terms of unexplored themes that may help organizations to

obtain value from BI systems.},

abstract = {Intercultural service encounters, in which customers and service employees from different cultures interact, are becoming more common in the market. Despite the importance of such encounters for international marketers, limited research attention has been directed to this area. Drawing on social exchange theory, this study examines how frontline employees' cultural intelligence (CQ) influences customer loyalty outcomes of service quality perceptions. Specifically, the authors propose that the three components of CQ?cognitive, emotional/motivational, and physical?have differential moderating effects on the perceived service quality (PSQ)-customer loyalty link and that these effects vary across two national markets. Data collected with a multirespondent (i.e., frontline service employees and customers) cross-cultural research design indicate that cognitive CQ negatively mitigates the impact of PSQ on customer loyalty in an emerging-market context while emotional/motivational CQ has a positive moderating effect in a mature-market setting. When service employees have high physical CQ, the positive role of PSQ in creating and maintaining customer loyalty is strengthened in both markets. The authors discuss these implications for theory and practice.},

The research conducts a field study of a real brand on its Facebook fan page to gather actual behavioral data. Both declarative and behavioral data are used to explain brand eWoM, based on 250 participants. Empirical results show that the Facebook activity has a positive influence on brand content sharing for active users (posters) but not for nonactive users (lurkers), while brand engagement positively affects brand content sharing for both active and nonactive users. Furthermore, brand community involvement does not have an influence on brand content sharing. Findings offer companies useful recommendations for using the determinants included in our research design to understand and analyze the sharing behaviors of users.},
