The Impact of Integration on Application Success and Customer Satisfaction in Mobile Device Platforms

Digital software platforms allow third parties to develop applications and thus extend their functionality. Platform owners provide platform boundary resources that allow for application development. For developers, plat- form integration, understood as the employment of plat- form resources, helps to realize application functionality effectively. Simultaneously, it requires integration effort and increases dependencies. Developers are interested to know whether integration contributes to success in hyper- competitive platform settings. While aspects of platform participation have been studied, research on a compre- hensive notion of integration and related implications are missing. By proposing a platform integration model, this study supports a better understanding of integration. Con- cerning dynamics related to integration, effects were tested using information from over 82,000 Apple AppStore applications. Regression model analysis reveals that application success and customer satisfaction is positively influenced by platform integration. To achieve superior results, developers should address multiple aspects of integration, such as devices, data, the operating system, the marketplace as well as other applications, and provide updates. Finally, the study highlights the importance for all platform participants and their possibilities to employ integration as a strategic instrument

Comparing Platform Core Features with Third-Party Complements. Machine-Learning Evidence from Apple iOS.

Software-based platforms have become omnipresent both in private and professional contexts. Platform owners constantly invest in platform evolution in that they update the technological core and enrich its feature base. The question arises how such platform core feature changes can be compared with third-party complements. We investigate this question in the context of an exploratory machine-learning based case study on Apple’s mobile platform iOS. By analyzing the changes to iOS over time and developing an approach using natural language processing, we are able identify functional overlaps between platform core features and complements. Our results suggest that platform core features are indeed functionally related to those of complementors and that the strategy of releasing novel platform core features changes over time. Besides, our approach enables us to assign platform core features to app categories. The analysis of functional overlaps raises relevant implications for research and practice

Governance Mechanisms in Digital Platform Ecosystems: Addressing the Generativity-Control Tension

Digital platform owners repeatedly face paradoxical design decisions with regard to their platforms’ generativity and control, requiring them to facilitate co-innovation whilst simultaneously retaining control over third-party complementors. To address this challenge, platform owners deploy a variety of governance mechanisms. However, researchers and practitioners currently lack a coherent understanding of what major governance mechanisms platform owners rely on to simultaneously foster generativity and control. Conducting a structured literature review, we connect the fragmented academic discourse on governance mechanisms with each aspect of the generativity-control tension. Next to providing avenues for prospective digital platform research, we elaborate on the double-sidedness of governance mechanisms in fostering both generativity and control

A Dynamic Model of Platform Versioning and Its Impact on Third-Party Developers

Using the system dynamics methodology, we leverage extant research on digital platforms and Agile development from the information systems and strategic management literatures to create a dynamic framework for considering the effect of digital platform versioning under different levels of market dynamism. We find that the impact of platform versioning release cycle time (RCT) and the scope of platform updates on platform outcomes (number of packages available and number of downloads) depends on market dynamism, sensitivity of users’ utility to app breakage, and value of the platform’s core functionality to the developers. Among other results, we show that smaller, incremental updates of functionality are generally preferable to larger, radical updates, even in dynamic markets. In contrast, longer RCTs are preferred in less dynamic markets, while small to moderate RCTs are preferred in more dynamic markets. We conclude with an agenda for future research

A rugged marine impact penetrometer for sea floor assessment

The utilization of marine sediments, as well as the awareness of hazards originating from unstable sea floor conditions, has increased since the second half of the last century. Accordingly, in situ tests have been developed to assess the geotechnical properties of marine sediments, with dynamic impact penetration testing being one of them. Thereby, CPT instrumentation or alternate sensors are used within the impact penetrometers. The aim of the research in this thesis is to investigate the applicability of an impact penetrometer (LIRmeter) for assessing geotechnical properties of marine sediments by sole measurement of acceleration. During a verification study, it was shown that dynamically acquired cone resistance data was interchangeable with data from the acceleration sensors. Further investigation by conducting laboratory tests on dense sands with low amounts of cohesive fines showed a good correlation between reference data from geotechnical tests and dynamically acquired data

Coastal Morphodynamics

Every year, a number of new forest pathosystems are discovered as the result of introduction of alien pathogens, host shifts and jumps, hybridization and recombination among pathogens, etc. Disease outbreaks may also be favored by climate change and forest management. The mechanisms driving the resurgence of native pathogens and the invasion of alien ones need to be better understood in order to draft sustainable control strategies. For this Special Issue, we welcome population biology studies providing insights on the epidemiology and invasiveness of emergent forest pathogens possibly by contrasting different scenarios varying in pathogen and host populations size, genetics, phenotype and phenology, landscape fragmentation, occurrence of disturbances, management practices, etc. Both experimental and monitoring approaches are welcome. In summary, this special issue focuses on how variability in hosts, pathogens, or ecology may affect the emergence of new threats to plant species

Introduction to Permanent Plug and Abandonment of Wells

This open access book offers a timely guide to challenges and current practices to permanently plug and abandon hydrocarbon wells. With a focus on offshore North Sea, it analyzes the process of plug and abandonment of hydrocarbon wells through the establishment of permanent well barriers. It provides the reader with extensive knowledge on the type of barriers, their functioning and verification. It then discusses plug and abandonment methodologies, analyzing different types of permanent plugging materials. Last, it describes some tests for verifying the integrity and functionality of installed permanent barriers. The book offers a comprehensive reference guide to well plugging and abandonment (P&A) and well integrity testing. The book also presents new technologies that have been proposed to be used in plugging and abandoning of wells, which might be game-changing technologies, but they are still in laboratory or testing level. Given its scope, it addresses students and researchers in both academia and industry. It also provides information for engineers who work in petroleum industry and should be familiarized with P&A of hydrocarbon wells to reduce the time of P&A by considering it during well planning and construction
