We analyze open source licensing and its effects on firms' decisions whether to use the open source technology or not and on the incentives for innovation, through a dynamic model of innovation and competition in an environment with a ladder-type technology. We model the basic features of the General Public License (GPL), one of the most popular open source licenses and study how firms behave under this license when competition is present. Under the GPL, any innovative findings using open source technology must also be open source in the subsequent periods, and this obligation creates a trade-off. We focus on how this trade-off affects incentives to use and build up the open source technology.

open source technology (OST) is now a powerful platform that has aptitudes in different extents. It provides many in-built software applications (e.g., Google Drive, One Drive, Dropbox etc.) at no cost which can be linked to different educational applications. These applications have some features along with synchronizing documents in multiple electronic devices like desktop, laptop, tabs, and mobile phones that are not even available in many of the paid software. Moreover, these technologies have pedagogical, technological and financial affordances especially for the developing countries, like Bangladesh that have budget constrains which results in the issue of sustainability. Considering these aspects, OST could be a suitable alternative for the users of educational institutions in Bangladesh that might evolve many added benefits. For example, OST does not require any additional maintenance cost like annual software updating, domain and hosting charges and so on. Therefore, the aim of this paper is to provide a detailed guideline of using this emerging technology for teacher training programme where trainers are the teachers and trainee teachers are the students. This conceptual paper shows the thorough procedures of how the users (teacher and student) can accomplish their specific tasks like producing, storing, sharing during the training programme by using OST. At the end of the training, the trainee teachers will be competent enough to use these applications to their own education settings. Thus teacher training would be a means to introduce these emerging technologies in many educational institutions within a short time. Moreover, using these technologies will not demand any cost other than the internet charge and hence the programme will be sustainable. An empirical research could be done in order to explore more potentiality in this emerging concept.

INTERNATIONAL JOURNAL OF COMPUTER INTEGRATED MANUFACTURING 2019年第4-5期32卷 366-384页

作者： Damjanovic-Behrendt, Violeta Behrendt, Wernher Salzburg Res IoT Grp Salzburg Austria

This paper discusses the design of a Digital Twin (DT) demonstrator for Smart Manufacturing, following an open source approach for implementation. open source technology can comprise of software, hardware and hybrid solutions that nowadays drive Smart Manufacturing. The major potential of open source technology in Smart Manufacturing lies in enabling interoperability and in reducing the capital costs of designing and implementing new manufacturing solutions. After presenting our motivation to adopt an open source approach for the design of a DT demonstrator, we identify the major implementation requirements of Smart Cyber Physical Systems (CPSs) and DTs. A conceptualisation of the core components of a DT demonstrator is provided and three technology building blocks for the realisation of a DT have been identified. These technology building blocks include components for the management of data, models and services. From the conceptual model of the DT demonstrator, we derived a high-level micro-services architecture and provided a case study infrastructure for the implementation of the DT demonstrator based on available open source technologies. The paper closes with research questions to be addressed in the future.

A digital time stamping system based on open source technologies (LINUX-UBUNTU, openTSA, openSSL, MySQL) is described in detail, including all important testing results. The system, called BALTICTIME, was developed under a project sponsored by the European Commission under the Program FP 6. It was designed to meet the requirements posed to the systems of legal and accountable time stamping and to be applicable to the hardware commonly used by the national time metrology laboratories. The BALTICTIME system is intended for the use of governmental and other institutions as well as personal bodies. Testing results demonstrate that the time stamps issued to the user by BALTICTIME and saved in BALTICTIME's archives ( which implies that the time stamps are accountable) meet all the regulatory requirements. Moreover, the BALTICTIME in its present implementation is able to issue more than 10 digital time stamps per second. The system can be enhanced if needed. The test version of the BALTICTIME service is free and available at http://***:8080/btws/ and http://***:8080/btws/

The Case for open source Software: The Interactional Discourse Lab

引用

APPLIED LINGUISTICS 2016年第1期37卷 100-120页

作者： Choi, Seongsook Univ Edinburgh Moray House Sch Educ Edinburgh EH8 9YL Midlothian Scotland

Computational techniques and software applications for the quantitative content analysis of texts are now well established, and many qualitative data software applications enable the manipulation of input variables and the visualization of complex relations between them via interactive and informative graphical interfaces. Although advances in text analysis have helped researchers mine text data for semantic content and identify language patterns in text with greater facility, interactional dynamics and patterns of talk have been neglected. This article introduces a new open-source tool, Interactional Discourse Lab. This tool is designed to map dynamics in spoken interaction and to represent them in easily accessible visual form, capturing aspects such as the frequency and patterning of exchanges, and the distribution of turns and discourse features. It is designed to contribute, with other analytical tools such as those used in text analysis, to the development of interactional topographies. The paper sets the tool within a wider case for the development of open-source software in applied linguistics as a platform for methodological innovation.

POLICY FUTURES IN EDUCATION 2012年第3期10卷 315-327页

作者： Quint-Rapoport, Mia Univ Toronto Off Vice Provost Fac & Acad Life Toronto ON Canada

This article addresses the question of understanding more about networked universities by looking at open source software developers working in academic contexts. It sketches their identities and work as an emerging professional community that both relies upon and develops digitally mediated networks and contributes to the progress of academic knowledge and scientific discoveries. The data for this study revolve around questionnaire responses from developers working on two open source software projects, one from the field of biology, the other from education. It provides a rare glimpse into a highly specialised social world. The study demonstrates how the commitments and ideals of open source software developers not only contribute to universities as digitally network institutions, but are foundational to their very constitution.

Digital archives and digital library projects are being initiated all over the world for materials of different formats and domains. To organize, store, and retrieve digital content, many libraries as well as archiving centers are using either proprietary or open-source software. While it is accepted that print media can survive for centuries with some physical preservation techniques, digital media requires continuous processes to keep it compliant with current technology. It is not only necessary to organize digital content but also important to preserve it to ensure accessibility, sustainability, and retrieval across time. This paper presents an analytical study along with observations regarding digital preservation support available in existing open-source digital library software (OSS-DL) based on test beds created for that purpose.
