摘要：Models play an important role in systems analysis and design (SAD). A diagrammatic model is defined as a mapping from a domain to a visual representation in such a way that relevant information is preserved to meet a specific goal. So far, cognitive research on diagram criteria in relation to task performance has been fragmented. The aim of this paper is to (1) consolidate research on the cognitive processing steps involved during understanding and task performance with diagrams, (2) consolida...

摘要：The growth of mobile devices coupled with advances in mobile technologies has resulted in the development and widespread use of a variety of mobile applications (apps). Mobile apps have been developed for social networking, banking, receiving daily news, maintaining fitness, and job-related tasks. The security of apps is an important concern. However, in some cases, app developers may be less interested in investing in the security of apps, if users are unwilling to pay for the added security....

摘要：The literature on information technology (IT) and government corruption in developing countries indicates contradictory evidence about the realization of anti-corruption effects. So far, there is no theoretical explanation of why the anti-corruption potential of IT demonstrated in some countries is not realized in many other countries. Drawing evidence from a case study of information systems interventions at Ghana customs over 35 years, we investigate how and why IT's anti-corruption potentia...

摘要：Despite the importance of information technology (IT) innovation in today's digitalized world, little research attention has been paid to examining how firms can incentivize IT innovation. To fill this gap, the current study investigates the impact of managerial incentives provided to chief executive officers (CEOs) on IT inno-vation, measured by the number of IT patents. In particular, we examine the role of risk-taking incentives provided to CEOs, captured by the sensitivity of CEO wealth to...

摘要：Through the lens of social movement theory, this paper investigates the drivers of individual users' social influence on Twitter during the Egyptian Revolution of 2011. Following this lens, we suggest an extended model of sustained social influence (that considers retweets as the measure of user influence) as a function of the duality of individual Twitter users' social actions and the underlying facilitating Twitter network structure. Based on an analysis of organic large-scale Twitter data o...

摘要：Constructs and indicators are central to the efforts of many researchers who seek to build and test theories and articulate rich narratives about real-world phenomena. For this reason, an extensive discourse exists about their nature. Increasingly, this discourse has become fraught with controversy. Using Bunge's (1977, 1979) ontology, I examine the nature of constructs and indicators as they are discussed in the extant literature. I define these concepts precisely, disentangle conceptual from...

摘要：Agile software development, a paradigm that emphasizes project team autonomy and the value of responding to changes over following standardized processes, has gained prominence in the software industry. Prior investigations on the adoptions of agile paradigms for software operations and their performance implications have typically focused on isolated aspects of software development processes. In this study, we adopt a configurational perspective of software operations and assess the causal im...

摘要：Screening is considered a necessary mechanism for alleviating information asymmetry but has also raised concerns about increased discrimination in online peer-to-peer market platforms. Paradoxically, providers of goods and services may also voluntarily forgo screening, even though it increases the risks and costs associated with poor matches. We examine who may choose to forgo screening and why, and its impact on their performance outcomes. Our study's empirical context is the Airbnb platform,...

摘要：Product review platforms in online marketplaces differ with respect to the granularity of product quality information they provide. While some platforms provide a single overall rating for product quality (also referred to as the single-dimensional rating scheme), others provide a separate rating for each individual quality attribute (also referred to as the multidimensional rating scheme). The multidimensional rating scheme is superior to the single-dimensional rating scheme, ceteris paribus,...

摘要：The Internet of Things (IoT) is increasingly transforming the way we work, live, and travel. IoT devices collect, store, analyze, and act upon a continuous stream of data as a by-product of everyday use. However, IoT devices need unrestricted data access to fully function. As such, they invade users' virtual and physical space and raise far-reaching privacy challenges that are unlike those examined in other contexts. As advanced IoT devices, connected cars offer a unique setting to review and ...
