Entrepreneurial Innovation: Killer Apps in the iPhone Ecosystem

The mobile applications (apps) industry has exhibited rapid entry and growth in the midst of a recession. Using unique data from the iPhone application ecosystem, we examine how the development of 'killer apps' (apps appearing in the top grossing rank) varies by market and app characteristics. We find that previous app experience and no updating increase the likelihood of becoming a killer game app, while more updates increase the likelihood of becoming a non-game killer app. Development opportunities, level of competition, and demand preferences are possible drivers of the opposing innovation process results in game and non-game markets.

A QoS aware resource allocation strategy for 3D A/V streaming in OFDMA based wireless systems.

Three-dimensional (3D) video is expected to be a “killer app” for OFDMA-based broadband wireless systems. The main limitation of 3D video streaming over a wireless system is the shortage of radio resources due to the large size of the 3D traffic. This paper presents a novel resource allocation strategy to address this problem. In the paper, the video-plus-depth 3D traffic type is considered. The proposed resource allocation strategy focuses on the relationship between 2D video and the depth map, handling them with different priorities. It is formulated as an optimization problem and is solved using a suboptimal heuristic algorithm. Numerical results show that the proposed scheme provides a better quality of service compared to conventional schemes.

Experimentation Strategies and Entrepreneurial Innovation: Killer Apps in the iPhone Ecosystem

Why are some entrepreneurial strategies more effective at generating innovations than others? We argue that the effectiveness of different strategies varies with market conditions defined by the supply tools (skills, technology) and demand structures (expectations, preferences) inherited from similar markets. To explore entrepreneurial innovation, we study new ventures in the iPhone application ecosystem. The development of “killer apps” (whether a software application appears in the top grossing rank on iTunes) is our key measure of innovation performance. We find robust evidence that simultaneous experimental strategies emphasizing products released concurrently are better suited to markets which inherit lots of skills, technology, clear expectations and demand for variety from similar markets. Sequential experimentation strategies emphasizing multiple versions produced over substantial time periods are better suited to more novel markets which inherit less skills and technology, unclear expectations and unit demand (non-games) from similar markets. Simultaneous strategies take advantage of the knowledge of customer preferences and technological development tools in similar markets and the heterogeneity of preferences in markets with demand for variety. Sequential strategies better deal with the challenges of developing the single best product for a novel market where there is both demand uncertainty and a lack of fundamental development tools.

Notes from the Field: Planting, Nurturing, and Watching Things Grow

Editors' Note: We invited a sample of AJPM's Editorial Board, supplement guest editors, and longtime colleagues and contributors to share their experiences and impressions of the impact of AJPM on their respective domains. We were particularly fond of Ken Powell's analogy to being "tenders of the planted seed"--as planters, weeders, and harvesters--watching and nurturing the growth of AJPM, and have elected to lead with his commentary.

Nearby Friend Alert: Location Anonymity in Mobile Geosocial Networks

Mobile geosocial networking services could be the killer app for next-generation mobile computing. However, the privacy issue--in particular, location privacy--has both users and government authors concerned. The authors address this issue for the "nearby friend alert" service, common in mobile geosocial networks. They review representative works on privacy-preserving proximity detection and present a new quantitative solution. They adopt the grid-and-hashing paradigm and develop optimal grid overlay and multilevel grids to increase the detection accuracy while saving the wireless bandwidth. Based on these techniques, they devise the client-side location update scheme and the server-side update handling procedure for continuous proximity detection. Simulation results show that their approach is efficient and scalable under various system parameters and user moving speeds.

Car sharing could be the EV's killer app

Parisians have learned to love electric cars by sharing them. Since the late 2011 launch of the French capital's Autolib car-sharing program, Parisians have taken its fleet of 1800 electric vehicles (EVs) on more than 2 million trips using 4000 dedicated charging points. That makes Paris one of the world's EV meccas, with more battery-powered cars on the road and more charging points than nearly any other city.

Why the West Grew Rich and the Rest Did Not, or How the Present Shapes Our Views of the Past

‘What makes a nation is the past’, wrote Eric Hobsbawm (1992: 3), ‘what justifies one nation against others is the past, and historians are the people who produce it’. Because historiography has always been so mixed up in politics, historians writing about nationalism ‘cannot but make a politically or ideologically explosive intervention’. A prominent recent example of such an explosive intervention is Niall Ferguson’s Civilization: The Six Killer Apps of Western Power. ‘Watching my three children grow up’, writes Ferguson (p. xix), ‘I had the uneasy feeling that they were learning less history than I had learned at their age, . . . because they had bad history books and even worse examinations’. Children, he said, should be taught that the Big Story of the last 500 years is the rise of Western domination of the world. Ferguson’s book (and the accompanying BBC/Channel 4 television series) sets out to do this, being designed ‘so that 17-years-olds will get a lot of history in a very digestible way, and be able to relate to it’ (see Porter, 2011). Ferguson’s book has created quite a stir (e.g. Bromwich, 2011; Porter, 2011), which escalated when Ferguson chose to publicly respond to Pankaj

Morning Dew on the web in Australia: 1992–1995

The World Wide Web arrived just as connections to the Internet were broadening from academe to the public generally. The Web was designed to support user-performed publishing and access to documents in both textual and graphical forms. That capability was quickly supplemented by means to discover content. The web browser was the ‘killer app’ associated with the explosion of the Internet into the wider world during the mid- 1990s. The technology was developed in 1990 by an Englishman, supported by a Belgian, working in Switzerland, but with the locus soon migrating to Illinois and then to Massachusetts in 1994. Australians were not significant contributors to the original technology, but were among the pioneers in its application. This paper traces the story of the Web in Australia from its beginnings in 1992, up to 1995, identifying key players and what they did, set within the broader context, and reflecting the insights of the theories of innovation and innovation diffusion.

The March of the Masses

The growth of mass spectrometry and more specifically liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)2 continues to accelerate in the clinical laboratory. A recent publication (1) provides readers with the opportunity to see where we have been, offering examples of how LC-MS/MS has impacted diagnostic care (steroids and clinical toxicology); where we are (pain management, peptide hormones, and single proteins); and where we are going (protein panels, increased throughput and automation). The techniques and technologies discussed posit 3 conclusions. First, the potential scope of mass spectrometry testing in clinical chemistry is prospectively limitless. Second, the tools and technologies being deployed will require further refinement for mass spectrometers to become established automated clinical analyzers. Third, the promise of reference interval measurement in support of clinical measurement has been practically realized for some applications and is feasible for others. Two central tenets are evident in each application. First, the “killer app” of mass spectrometry incorporates the use of a stable labeled isotope of the analyte(s) being measured with various isotope dilution strategies for calibration. An ideal internal standard is both physiologically unique relative to the composition of the test specimen and physicochemically identical to the analyte, such that recovery, separation, and ionization in each specimen are controlled and corrected: the perfect analytical control for each specimen. Second, multiconcentration calibrators defining the analytical range, often bracketing QCs and samples, control for instrument response drift and deviations from detection linearity over the course of analysis. The combination of these two principles, coupled with the specificity of measurement that LC-MS/MS affords, provides the opportunity for reference level measurement. This, however, comes with historical baggage; LC-MS/MS is almost exclusively deployed in a batch mode of analysis in clinical laboratories. In this issue of Clinical Chemistry , Olson et al. (2) illuminate, illustrate, and iterate …

ICT for Development: Solutions Seeking Problems?

This paper investigates information and communication technologies for development (ICT4D) projects from around the world. It finds that computer and Internet promotion schemes usually fail despite active support, but mobile penetration in even the poorest countries is deepening organically. It argues that mobiles have emotional appeal because talking is a universal psycho-sociological propensity while the other two are principally utilitarian technologies that have to generate returns on investment. The search for killer apps is likely to be fruitless because technological adoption is conditional upon need and absorptive capacity. The paper raises questions about the continuing support for ICT4D among proponents.

The Future of Healthcare Informatics: It is not what you Think

Electronic health records (EHRs) offer many valuable benefits for patient safety, but it becomes apparent that the effective application of healthcare informatics creates problems and unintended consequences. One problem that seems particularly challenging is integration. Painfully missing are low-cost, easy to implement, plug-and-play, nonintrusive integration solutions—healthcare's “killer app.” Why is this?We must stop confusing application integration with information integration. Our goal must be to communicate data (ie, integrate information), not to integrate application functionality via complex and expensive application program interfaces (APIs). Communicating data simply requires a loosely coupled flow of data, as occurs today via email. In contrast, integration is a chief information officer's nightmare. Integrating applications, when we just wanted a bit of information, is akin to killing a gnat with a brick.
