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.

Procedia - Social and Behavioral Sciences 2015年 195卷 862-871页

作者： Mahbub Hasan Shahadat Hossain Khan Che Kum Clement Department of Technical and Vocational Education Islamic University of Technology Gazipur-1704 Bangladesh Centre for Research on Computer Supported Learning and Cognition (CoCo) Faculty of Education and Social Work The University of Sydney NSW 2006 Australia

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.

DIGITAL LIBRARY PERSPECTIVES 2022年第3期38卷 318-331页

作者： Okuonghae, Omorodion Achugbue, Edwin Iroroeavwo Samuel Adegboyega Univ Univ Lib Ogwa Nigeria Delta State Univ Dept Lib & Informat Sci Cleveland MS USA

Purpose The continuous advancement in technology has disrupted practices in many sectors, including education. Thus, this study aims to examine digital librarianship practice and open access technology use for sustainable development in Nigeria. Design/methodology/approach The survey type of descriptive research design was adopted in this study while the population of the study comprised librarians in universities in Delta State. A total of 38 randomly selected librarians from four universities in Delta State were used for this study, and the data collected were analysed using descriptive statistics. Findings This study revealed that the level of digital librarianship practice in university libraries in Delta State for sustainable development is low;just as social media tools, open source integrated library systems and Google Cloud Platforms are the most commonly used open access technologies in the libraries. Furthermore, this study showed that perennial factors such as poor funding of education, inadequate quality educational infrastructure, mismanagement of education fund among others are hindrance to sustainable development in the country's educational sector. Research limitations/implications This study is limited in its use of only one state (out of 36 states and the Federal Capital Territory, Abuja) in Nigeria for this research. Also, social desirability bias on the part of the respondents could have influenced the pattern in which the respondents reacted to items in section D. Practical implications This study has practical implications for the sensitization and training of librarians towards leveraging on the various open access technologies in delivering effective library and information services required in the Fourth Industrial revolution. Originality/value This study seeks to pioneer a new area of focus by examining digital librarianship practice and open access technology use as enablers of sustainable development.

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.

Determining the Speed of Sound as a Function of Temperature Using Arduino

PHYSICS TEACHER 2019年第2期57卷 114-115页

作者： Hahn, Marcelo Dumas de Oliveira Cruz, Frederico Alan Carvalho, Paulo Simeao Univ Porto Inst Fis Mat Porto Portugal Univ Porto Fac Ciencias Porto Portugal Univ Fed Rural Rio de Janeiro Dept Phys Seropedica Brazil Univ Porto Unidade Ensino Ciencias Dept Fis & Astron Fac Ciencias Porto Portugal

When sound waves are taught at the secondary level, the speed of propagation of sound is one of the most important characteristics to be analyzed. However, it is very common in textbooks that the value of sound speed in air is considered constant regardless of the experimental conditions. The great question is that since sound is a mechanical wave, its speed is influenced by the medium of propagation and also by the temperature. In most cases, the techniques reported for that goal usually make use of expensive equipment and techniques that may not be affordable and/or easy to implement in schools, which is an experimental limitation for the teachers to show this influence on their students. In this work, we present a low-cost experimental apparatus, controlled by the open source electronic platform Arduino®, with which it is possible to determine the speed of propagation of sound as a function of the temperature for a short measuring region, thus enabling the students to verify experimentally this important feature of sound waves.

This paper builds on the dimensions of ambiguity, as stated in the article by Gaver et al. [1]. It proposes to transfer the phenomenon of ambiguity to the domains of Social and Public Design, which are not only in need of generating attention in public spaces but also in funnelling long-term interest to deploy citizen participation. This paper discusses the categories of ambiguity on a theoretical level and adds relevant Research-Through-Design case studies that examine design knowledge in practice.

Fast and furious: how the open vs closed dilemma affects the technology diffusion dynamic

引用

MANAGEMENT DECISION 2018年第4期56卷 867-890页

作者： Parmentola, Adele Simoni, Michele Tutore, Ilaria Univ Naples Parthenope Dept Management & Quantitat Studies Naples Italy

Purpose The purpose of this paper is to propose a comprehensive theoretical framework to explain the different diffusion dynamics of a technology realized under an open source (OS) regime vs a technology realized under a closed-proprietary (CP) regime. Design/methodology/approach Following a systematic combining approach, theoretical predictions derived from literature on diffusion of innovation and on open innovation were matched with empirical observations derived from a case study of two mobile operation systems, which were released under different technological regimes. Findings This paper proposes a theoretical framework and a set of original theoretical propositions that can help to explain the differences in the diffusion dynamics of technologies that are released under different regimes (i.e. CP vs OS). Research limitations/implications This paper provides managers a better understanding of the diffusion dynamics of technologies released according to an open innovation strategy. In addition, the empirical case study improves the understanding of an important industry (the MOS industry) that has not been fully investigated from the innovation diffusion perspective. Nevertheless, the efficacy and generalizability of the theoretical framework proposed in this paper require future empirical tests. Originality/value This paper makes an original contribution to the open innovation and innovation diffusion literature by linking, in a conceptual model, three antecedents of the diffusion of a new technology that previous literature has considered only separately: the regime under which the technology is released (OS vs CP), the contingencies related to the characteristics of the technology and to the network of its adopters, and the resulting barriers to adoption.
