In this study, the authors develop a structural model that combines a macro diffusion model with a micro choice model to control for the effect of social influence on the mobile app choices of customers over app stores. Social influence refers to the density of adopters within the proximity of other customers. Using a large data set from an African app store and Bayesian estimation methods, the...

The aim of the present work is to study the evolution of organizational knowledge within Academic Spin-off (ASO) firms throughout their life cycle. The exploitation of tacit and indivisible new knowledge developed in the context of academic institutions entails agency problems of different nature; one way to address such challenges is the creation of new business firms by the inventors. At the ...

The trend of application stores is currently at a peak. However, the lack of dynamic composition for complex solutions is the largest downside of the app store model, since solutions are increasingly created as compositions of multiple solutions, APIs, and applications. Therefore, in this vision paper, a superior model, solution composers, is proposed to the app store model. A conceptual framew...

Previous studies have emphasized the necessity for software platform owners to govern their platform ecosystem in order to create durable opportunities for themselves and the app developers that surround the platform. To date, platform ecosystems have been widely analyzed from the perspective of platform owners, however, how and to what extent app developers collaborate with their peers needs t...

OBJECTIVES This study was conducted to develop a smartphone application (app) as an educational learning instrument for coronary artery disease (CAD) patients and to assess the users' level of satisfaction. METHODS This methodological research involves elicited learning content for CAD patients to develop a learning instrument using the smartphone app. The app was developed according to the s...

This paper examines the effect of the freemium strategy on Google Play, an online marketplace for Android mobile apps. By analyzing a large panel dataset consisting of 1,597 ranked mobile apps, we found that the freemium strategy is positively associated with increased sales volume and revenue of the paid apps. Higher sales rank and review rating of the free version of a mobile app both lead to...

In this position paper, we present MoCCha, a mobile campus application used not only as a subject of research, but as a research platform for a number of scientific disciplines. Following the approach of using an app that is available from a mobile application store, we want to study user behavior in the field with the aim for ecological validity that humansubject studies in lab environments ar...

The Substitutable Medical Applications, Reusable Technologies (SMART) Platforms project ( www.smartplatforms.org ) seeks to develop an iPhone-like health information technology platform with substitutable apps constructed around core services. It is funded by a grant from the Office of the National Coordinator of Health Information Technology's Strategic Health IT Advanced Research Projects (SH...

As a network visualization and analysis platform, Cytoscape relies on apps to provide domain-specific features and functions. There are many resources available to support Cytoscape app development and distribution, including the Cytoscape App Store and an online "cookbook" for app developers. This article collection is another resource to help researchers find out more about relevant Cytoscape...

This paper proposes the use of graphical representations – colloquially referred to as “icons” – of app-store program categories and provides evidence via a user study that these icons can be understood by young children (aged 4-8). Given the rapid growth of this user base, providing such graphical representations is important to aid young children in navigating (under usual parental supervisio...
