Technologies for teaching abound, but many of them are proprietary systems and software that require institutional and individual subscriptions for use. Instructors and librarians in higher education have open source and free options for many types of teaching technologies. While some of these technologies are free to users, open source goes beyond that and makes the source code that runs it available as well. These provide more options to enhance teaching.

This paper will provide an overview of the open source landscape and evaluate free and open source technologies of potential use in the college or university classroom.

The paper found a number of free and open source tools appropriate for teaching and learning in higher education. These tools may possibly generate savings over proprietary tools, but could have other costs such as additional learning investment or require hosting. Additionally, free and open source technologies provide students with knowledge about tools that they can continue to access after graduation. Libraries have a role in connecting their constituencies to these tools.

The paper provides descriptive information about a variety of tools for teaching and learning in higher education, as well as examples from the literature of how the tools might be integrated into the classroom and into library instruction.

The purpose of this paper is to discuss how to integrate secure, open‐source and mobile‐based system with the Moodle learning management system (MLMS) then describe the implementation of a campus‐wide mobile learning environment with short messaging system (SMS) and how this platform is incorporated with the student's learning environment.

This paper discusses how existing mobile‐based systems are currently being used for academic activities and describes current research within the same area. Then, the paper gives the detailed design of secure, open‐source and Moodle integrated mobile learning environment that facilitates sending short messages via an SMS gateway.

Statistical analysis of results during a campus‐wide implementation of the system revealed students’ preference in studying with a group while using mobile technologies for academic activities.

With the advent of mobile technology, integrating an open‐source secure mobile learning environment, coupled with a short message service, into a learning management system (LMS) has been a challenging task in mobile learning platforms during the past few years. Hence, this research project presents a significant importance for both students and teachers by proposing a campus‐wide mobile learning environment with open source software providing unlimited usage.

The purpose of this study is to examine the state of the literature on knowledge sharing in open source software (OSS) development communities by examining the existing research and identifying the knowledge gaps and opportunities that can inform areas for future research.

A systematic literature review was conducted of literature published between January 2011 and February 2023. A total of 24 papers were identified and reviewed.

The findings reveal that the literature on knowledge sharing in OSS development communities from developing countries are limited. Additionally, there exists a limited focus on the development of frameworks to support knowledge sharing in OSS communities. The transient nature of OSS development contributors’ results in knowledge loss; thus, knowledge retention needs further investigation.

This study only included papers whose titles, keywords or abstracts included the search keywords “knowledge sharing” and “Open Source Software”. While the keywords were carefully applied, when applying the search, it cannot be ruled that some relevant studies might have been missed. The study was also limited to conferences and journal papers published in English. Despite the limitations, the study provides a systematic review of knowledge sharing in OSS communities and presents findings that can be useful to researchers and practitioners interested in this area.

The study provides a systematic literature review of published papers and identifies themes and future research areas on knowledge sharing in OSS communities. Additionally, this review offers insights into future research avenues for theory, content and context on knowledge sharing in OSS development communities.

The paper aims to develop a systematic approach to design, integrate, and implement a set of crypto cores in a system-on-chip SoC) environment for data security applications. The advanced encryption standard (AES) and PRESENT block ciphers are deployed together, leading to a common crypto chip for performing encryption and decryption operations.

An integrated very large-scale integration (VLSI) architecture and its implementation for the AES and PRESENT ciphers is proposed. As per the choice, the architecture performs encryption or decryption operations for the selected cipher. Experimental results of the field-programmable gate array (FPGA) and application-specific integrated circuit (ASIC) implementations and related design analysis are provided.

FPGA implementation of the architecture on Xilinx xc5vfx70t-1-ff1136 device consumes 19% slices, whereas the ASIC design is implemented in 180 nm complementary metal-oxide semiconductor ASIC technology that takes 1.0746 mm² of standard cell area and consumes 14.26 mW of power at 50 MHz clock frequency. A secure audio application using the designed architecture on an open source SoC environment is also provided. A test methodology for validation of the designed chip using an FPGA-based platform and tools is discussed.

The proposed architecture is compared with a set of existing hardware architectures for analyzing various design metrics such as latency, area, maximum operating frequency, power, and throughput.

The aim of this study is to provide a theoretical extension to the private‐collective model of information sharing along with an empirical test with users of a social bookmarking website.

The paper includes a survey of 112 users of an actual bookmarking site recruited through an online research panel firm. The survey consisted of scales adapted from the literature as well as scales developed by the authors.

The results indicate that contributions to a social bookmarking site are a combination of intentional and unintentional contributions. A significant predictor of intentional public contributions of bookmarks is an egoistic motivation to see one as competent by contributing valuable information. However, there is also a significant but negative relationship between altruism and public contribution whereby users concerned with the needs of others limit their public contributions.

The sample consists of users of a particular social bookmarking site (Yahoo!'s MyWeb). Therefore, the results may not be generalizable to other social bookmarking websites, different types of social networks, or other contexts lacking the public/private option for contributions. Second, since the data comes from a cross‐sectional survey, as opposed to a longitudinal study, the causal relations posited in the model and substantiated with the statistical analyses can only be inferred based on the authors’ theoretical development. Third, although the size of the sample (112 respondents) is appropriate for PLS analysis it may have been insufficient to detect other significant relationships.

Administrators of social bookmarking sites should incorporate incentive and feedback mechanisms to inform contributors whether they contributions have been used (for example, with times viewed) and/or deemed useful (with numeric or qualitative ratings).

The results suggest that both selfish motivations associated with the need to feel competent (egoism), as well as selfless concerns for the needs of other users (altruism) drive intentional contributions to the public repository in social bookmarking systems. These two counterbalancing forces indicate that a mix of egoism and altruism is crucial for the long‐term sustainability of social web sites based on information sharing.

This study provides theoretical explanations and empirical evidence of egoism and altruism as significant explanations for cooperation in private‐collective models, such as the ones represented by social bookmarking systems.

Cooperative knowledge spaces create new potentials for the experimental fields in natural sciences and engineering because they enhance the accessibility of experimental setups through virtual laboratories and remote technology, opening them for collaborative and distributed usage. A concept for extending existing virtual knowledge spaces for the means of the technological disciplines (“ViCToR‐Spaces” ‐ Virtual Cooperation in Teaching and Research for Mathematics, Natural Sciences and Engineering) is presented. The integration of networked virtual laboratories and remote experiments (“NanoLab Approach”), as well as an approach to community‐driven content sharing and content development within virtual knowledge spaces (NanoWiki) are described.

There has been a recent surge of interest in open source software development, which involves developers at many different locations and organizations sharing code to develop and refine programs. To an economist, the behavior of individual programmers and commercial companies engaged in open source projects is initially startling. This paper makes a preliminary exploration of the economics of open source software. We highlight the extent to which labor economics, especially the literature on career concerns’, can explain many of these projects’ features. Aspects of the future of open source development process, however, remain somewhat difficult to predict with off-the-shelf’ economic models.

Open Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data.

The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample.

The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning.

The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning.

This study allows the authors to highlight two main practical contributions for OSSCs’ directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables.

This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).
