Abstract: In a thought-provoking paper published in EJIS more than a decade ago, Lyytinen and colleagues asked the question, why does the “old world” perform poorly in high academic impact publishing? This triggered a lively debate on the epistemological and methodological traditions, preferences, and research practices of Europeans versus North Americans that has lasted until today. Is it still true, we asked ourselves, that European scholars generate less academic impact than their North American colleagues? Is the European research context indeed disadvantageous for developing high academic impact research? In this paper, we set out to explore these questions by analysing the Google Scholar profiles of 1713 IS researchers from all over the world. Our findings show that Northern and Western European scholars no longer seem to differ significantly from their North American peers, even though the different research contexts still exercise a certain level of influence. However, is this a development the “old world” desires? We provide an assessment and some suggestions for the future of European IS research. Collapse

Abstract: User privacy protection is a vital issue of concern for online social networks (OSNs). Even though users often intentionally hide their private information in OSNs, since adversaries may conduct prediction attacks to predict hidden information using advanced machine learning techniques, private information that users intend to hide may still be at risk of being exposed. Taking the current city listed on Facebook profiles as a case, we propose a solution that estimates and manages the exposure risk of users' hidden information. First, we simulate an aggressive prediction attack using advanced state-of-the-art machine learning algorithms by proposing a new current city prediction framework that integrates location indications based on various types of information exposed by users, including demographic attributes, behaviors, and relationships. Second, we study prediction attack results to model patterns of prediction correctness (as correct predictions lead to information exposures) and construct an exposure risk estimator. The proposed exposure risk estimator has the ability not only to notify users of exposure risks related to their hidden current city but can also help users mitigate exposure risks by overhauling and selecting countermeasures. Moreover, our exposure risk estimator can improve the privacy management of OSNs by facilitating empirical studies on the exposure risks of OSN users as a group. Taking the current city as a case, this work offers insight on how to protect other types of private information against machine-learning prediction attacks and reveals several important implications for both practice management and future research.

Abstract: Context factors have lasting impacts on people’s sentiments. Exploring impacts that different contexts have on sentiments can be crucial for managing the increasing number of communications companies nowadays maintain with customers via social media channels. To help companies prevent impacts of negative word of mouth, we provide an overview about sentiment-influential contexts for tweets as one kind of social media texts previously discussed within the literature. We collected an overall amount of 358.923.210 tweets and performed analysis to uncover the effects of continents, mobile devices’ operating systems (OS) and the combination of both on sentiments expressed within tweets. Our results show remarkable differences for tweets originating from North America and Apple devices, which turned out to be the tweets with the lowest sentiments compared to the other continents and the mobile OS Android.

Abstract: The information revolution leaves its mark on businesses, resulting in organizations looking for digital inno­ vation (DI) to apply to their business processes and anticipate competitors. Since the interplay between business process management (BPM) and DI has been underdeveloped, this mixed-methods article investigates the strength and nature of the relationship. We supplement the findings of an international survey (stage 1) with explanations from an expert panel (stage 2) to generalize a positive yet moderate link because of manifold contextual factors affecting strategic decision-making. We extend the technology–organization–environment (TOE) framework and profile organizations along their digital process innovation (DPI) mastery in a readiness matrix. Collapse

Abstract: This manuscript describes our experiences writing a future-oriented, next-generation theory. We provide advice for other theory authors and for reviewers of theory papers. Our advice relates to theorizing challenges as well as the practical and logistical challenges associated with publishing a theory paper. We conclude by calling attention to areas that warrant greater attention from IS researchers and by describing opportunities for future-oriented theoretical and empirical research. We explain how future-oriented approaches to speculative design and radical reimagining can inform new IS theories. Future-oriented approaches to forecasting and scenario-based research can be leveraged in empirical studies. We hope this editorial will inspire others to theorize and conduct research with an eye to the future. We argue that successful future-oriented research will consider possible futures that are high-likelihood and/or high-risk/reward, and will equip the IS discipline going forward, whatever future may arise.

Abstract: The availability of healthcare data has exponentially grown, both in quantity and complexity. The speed of this evolution has generated new challenges for translating complex data into effective evidence-informed policy. Visual analytics offers new capacity to analyze healthcare systems and support better decision-making. We conducted a systematic scoping review to look for evidence of visual analytics approaches being applied to mental healthcare systems and their use in driving policy. We found 79 relevant studies and categorized them in two ways: by study purpose and by type of visualization. The majority (67.1%) of the studies used geographical maps, and 11% conducted highly complex studies requiring novel visualizations. Significantly, only 15% of the studies provided information indicating high levels of usability for policy and planning. Our findings suggest that while visual analytics continues to evolve rapidly, there is a need to ensure this evolution reflects the practical needs of policy makers. Collapse

Abstract: Online reviews and word of mouth are crucial to consumers. We proposed a model on the basis of a sentiment analysis in terms of positive and negative words and the concept of credibility of reviewers. This study used TripAdvisor to examine the proposed model and selected 10 out of 271 hotels in Las Vegas between January and February 2015. We also collected 116 samples around world to prove the feasibility and validity. Through sentiment analysis, we determined that the overall ranking of the 10 hotels decreased. The credibility factor has a higher influence on hotel ranking than the sentiment analysis does. These results revealed that negative emotions and low-credibility reviews have a high influence on hotel ranking. The findings from participants also confirmed emotional text in review title and content and credibility of reviewer are important for adjusting original rating. Collapse

Abstract: The smart city concept is used as tool by local and municipal governments to deliver benefits relating to people, government, economy, mobility, environment and living. By embedding technologies and the internet of things in the city’s infrastructure, smart cities aim to generate insights that drive local improvements and accrue to a global level. The smart city is also viewed as a transformative lever for government. As cities move beyond smart city pilot showcasing projects, they face the challenge of embedding smart city initiatives in business-as-usual. Despite ambitious goals and high stakes, little is known about the work that leaders perform in undertaking this transformation. This study explored the leadership practice of smart city leaders in Denmark, Holland, USA, Australia and New Zealand. We focus on how leaders drive transformation from showcasing to becoming a sustainable smart city, and the challenges faced. As result we present a framework of six barriers to overcome and five enacted leadership roles to transform the city of today to a future sustainable smart city. We use institutional logics as a lens to discuss and explain the challenges faced by city leaders and their critical role as innovation agents and boundary spanners in smart city transformation.

Developer Centrality and the Impact of Value Congruence and Incongruence on Commitment and Code Contribution Activity in Open Source Software Communities

Abstract: Open source software (OSS) communities are dependent on the code contributions of developers who, in many cases, never meet face-to-face and collaborate primarily through technology-enabled means. With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person-environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.

Abstract: YouTube has become the standard social network for the dissemination of university multimedia content, but the impact of academic online videos has been scarcely researched. This study covers this gap and provides a new dimension to evaluate university performance. Data and statistics of 416 YouTube accounts and ca. 190,000 online videos of world class universities are gathered. The H-index is adapted to quantify the online video impact, universities are ranked accordingly and the correlates of impact are analyzed. The H-based ranking of online video impact is closely related to standard rankings of world class universities, with a stronger relation than that with other online video related metrics. Research productivity and online video orientation of a university are robustly related to online video impact, whereas teaching, university size and geographical location are not. Collapse
