How open is open enough?: Melding proprietary and open source platform strategies

Computer platforms provide an integrated architecture of hardware and software standards as a basis for developing complementary assets. The most successful platforms were owned by proprietary sponsors that controlled platform evolution and appropriated associated rewards. Responding to the Internet and open source systems, three traditional vendors of proprietary platforms experimented with hybrid strategies which attempted to combine the advantages of open source software while retaining control and differentiation. Such hybrid standards strategies reflect the competing imperatives for adoption and appropriability, and suggest the conditions under which such strategies may be preferable to either the purely open or purely proprietary alternatives

An Exploratory Study into Open Source Platform Adoption

Research on open source software has focused mainly on the motivations of open source programmers and the organization of open source projects [17] [19]. Some researchers portray open source as an extension of the earlier open systems movement [36]. While there has been some research on open-systems software adoption by corporate MIS organizations [4] the issue of open source adoption has received little attention. We use a series of interviews with MIS managers to develop a grounded theory of open source platform adoption. We contrast this to prior academic and popular reports about the adoption of open source

Contrasting Community Building in Sponsored and Community Founded Open Source Projects

Prior characterizations of open source projects have been based on the model of a community-founded project. More recently, a second model has emerged, where organizations spinout internally developed code to a public forum. Based on field work on open source projects, we compare the lifecycle differences between these two models. We identify problems unique to spinout projects, particularly in attracting and building an external community. We illustrate these issues with a feasibility analysis of a proposed open source project based on VistA, the primary healthcare information system of the U.S. Department of Veterans Affairs. This example illuminates the complexities of building a community after a code base has been developed and suggests that open source software can be used to transfer technology to the private sector

Policy Challenges of Open, Cumulative, and User Innovation

This Article contrasts the implications of these three theories of interorganizational innovation (Henry Chesbrough\u27s, Eric von Hippel\u27s, and Suzanne Scotchmer\u27s) for the Chandlerian model of industrial innovation. It then analyzes the potential impact of various public policies upon such interorganizational innovation and suggest opportunities for research in this area

Lost, beat, blank: The punk unconscious in subversive and transgressive cultural productions

Although punk was not used as a signifying term for a subculture or its cultural production until the 1970s, the punk spirit can be identified within cultural texts that precede the term. A punk aesthetics includes rejection of societal norms, class-consciousness, and spontaneity, or a do-it-yourself (DIY) approach that is antagonistic toward the modes of production. In this thesis, I claim and develop a concept I call the punk unconscious; in the texts I examine, punk aesthetics can be found just below the surface through the employment of specific theoretical frameworks, namely Fredric Jameson’s political unconscious and Mikhail Bakhtin’s dialogic imagination. This thesis will examine the works of three major movements of the twentieth century: the Lost Generation, the Beat Generation, and the Blank Generation. In my analysis, texts by Ernest Hemingway, Jack Kerouac, William S. Burroughs, and Richard Hell will be read through the lens of the punk unconscious. Punk songs inspired by the assassination of President John F. Kennedy will also be analyzed through the course of this thesis to establish a shift in mindset and consciousness. The goal is to recognize the role of the punk unconscious within these movements, as well as the shift from unconscious to conscious acts that fit within a punk aesthetics and sensibility

Interfaces, modularity and ecosystem emergence: How DARPA modularized the semiconductor ecosystem

Scholars have identified the pivotal role that modularity plays in promoting innovation. Modularity affects industry structure by breaking up the value chain along technical interfaces, thereby allowing new entrants to specialize and innovate. Less well-understood is where modularity comes from. Firms seem to behave consistently with the theory in some settings, especially the information technology sector, but not in others, such as automobiles. Here we show how the government has a role to play in generating open interfaces needed for modularity, utilizing a case study of the semiconductor industry from 1970 to 1980. We show how the Defense Department\u27s support for this effort aligned with its mission-based interest in semiconductors. We thus contribute a new source of open standards to the modularity literature, as well as a new analytical perspective to the public research funding literature

Mnemonics as signs of memory: semiotics and agency

This paper engages the question of the extended mind hypothesis, specifically in terms of memory and mnemonics. I use the case of an external object which is set to trigger a memory internally, but is not the memory, to explore the idea of extension versus distribution. I use the example of tzitzit, which is a garment worn by observant Jewish men, where is states in scripture that seeing the tassels attached to the garment are supposed to trigger a specific memory. The point of the essay is that extension is merely a metaphysical commitment, and that this commitment leads to some ethical issues

RNA-Seq optimization with eQTL gold standards.

BackgroundRNA-Sequencing (RNA-Seq) experiments have been optimized for library preparation, mapping, and gene expression estimation. These methods, however, have revealed weaknesses in the next stages of analysis of differential expression, with results sensitive to systematic sample stratification or, in more extreme cases, to outliers. Further, a method to assess normalization and adjustment measures imposed on the data is lacking.ResultsTo address these issues, we utilize previously published eQTLs as a novel gold standard at the center of a framework that integrates DNA genotypes and RNA-Seq data to optimize analysis and aid in the understanding of genetic variation and gene expression. After detecting sample contamination and sequencing outliers in RNA-Seq data, a set of previously published brain eQTLs was used to determine if sample outlier removal was appropriate. Improved replication of known eQTLs supported removal of these samples in downstream analyses. eQTL replication was further employed to assess normalization methods, covariate inclusion, and gene annotation. This method was validated in an independent RNA-Seq blood data set from the GTEx project and a tissue-appropriate set of eQTLs. eQTL replication in both data sets highlights the necessity of accounting for unknown covariates in RNA-Seq data analysis.ConclusionAs each RNA-Seq experiment is unique with its own experiment-specific limitations, we offer an easily-implementable method that uses the replication of known eQTLs to guide each step in one's data analysis pipeline. In the two data sets presented herein, we highlight not only the necessity of careful outlier detection but also the need to account for unknown covariates in RNA-Seq experiments
