Managing the boundary of an 'open' project

In the past ten years, the boundaries between public and open science and commercial research efforts have become more porous. Scholars have thus more critically examined ways in which these two institutional regimes intersect. Large open source software projects have also attracted commercial collaborators and now struggle to develop code in an open public environment that still protects their communal boundaries. This research applies a dynamic social network approach to understand how one community-managed software project, Debian, developed a membership process. We examine the project's face-to-face social network over a five-year period (1997-2001) to see how changes in the social structure affected the evolution of membership mechanisms and the determination of gatekeepers. While the amount and importance of a contributor's work increased the probability that a contributor would become a gatekeeper, those more central in the social network were more likely to become gatekeepers and influence the membership process. A greater understanding of the mechanisms open projects use to manage their boundaries has critical implications for research and knowledge-producing communities operating in pluralistic, open and distributed environments.open source software; social networks; organizational design; institutional design;

Embedding accessibility and usability: considerations for e-learning research and development projects

This paper makes the case that if e‐learning research and development projects are to be successfully adopted in real‐world teaching and learning contexts, then they must effectively address accessibility and usability issues; and that these need to be integrated throughout the project. As such, accessibility and usability issues need to be made explicit in project documentation, along with allocation of appropriate resources and time. We argue that accessibility and usability are intrinsically inter‐linked. An integrated accessibility and usability evaluation methodology that we have developed is presented and discussed. The paper draws on a series of mini‐case studies from e‐learning projects undertaken over the past 10 years at the Open University

Effective communication in requirements elicitation: A comparison of methodologies

The elicitation or communication of user requirements comprises an early and critical but highly error-prone stage in system development. Socially oriented methodologies provide more support for user involvement in design than the rigidity of more traditional methods, facilitating the degree of user-designer communication and the 'capture' of requirements. A more emergent and collaborative view of requirements elicitation and communication is required to encompass the user, contextual and organisational factors. From this accompanying literature in communication issues in requirements elicitation, a four-dimensional framework is outlined and used to appraise comparatively four different methodologies seeking to promote a closer working relationship between users and designers. The facilitation of communication between users and designers is subject to discussion of the ways in which communicative activities can be 'optimised' for successful requirements gathering, by making recommendations based on the four dimensions to provide fruitful considerations for system designers

A gentle transition from Java programming to Web Services using XML-RPC

Exposing students to leading edge vocational areas of relevance such as Web Services can be difficult. We show a lightweight approach by embedding a key component of Web Services within a Level 3 BSc module in Distributed Computing. We present a ready to use collection of lecture slides and student activities based on XML-RPC. In addition we show that this material addresses the central topics in the context of web services as identified by Draganova (2003)

NORTH BOTTOMS: A PARTICIPATORY REDEVELOPMENT & SUSTAINABLE COMMUNITY ENGAGEMENT PROCESS

This project addressed the economic, social, and environmental ill effects occurring in the North Bottoms in Lincoln, Nebraska. This neighborhood requires the use of innovative community engagement to counteract minimal resources, civic engagement, and social capital in order to accomplish sustainable redevelopment when traditional methods have been unsuccessful. The initial goal of the project was to involve citizens in the design process to create an effective and development strategy and design project for the neighborhood. Although traditional methods were sufficient to develop a comprehensive approach to sustainable development, it became obvious through engagement with citizens and civic officials that a new model would be beneficial to maintain communication with citizens, actively engage and incentivize developers, and provide an accessible means to sharing information. The problem being faced by the North Bottoms neighborhood was larger than a redevelopment project. Direction of the project then changed to incorporate a theoretical web-based model of community engagement centered on the redevelopment process was proposed to address these needs. This theoretical tool, the Social Capacity Website, addressed the means by which local government can actively promote a neighborhood’s agenda for the goal of a sustainable neighborhood while continuing to support public-private partnerships and development incentives thus providing a more effective model of redevelopment. These traditional methods of redevelopment often lack multi-directional communication and availability of information resulting in a lack of support from residents and design that does not maximize site potential. The theoretical tool developed, the Social Capacity website, works to address these needs

Self-Organization in Urban Regeneration: A Two-Case Comparative Research

Urban regeneration processes in which local stakeholders take the lead are interesting for realizing tailor made and sustainable urban regeneration, but are also faced with serious difficulties. We use the concept of self-organization from complexity theory to examine the relationship between local stakeholders’ initiatives and vital urban regeneration processes. We conducted a two-case comparative research, Caterham Barracks and Broad Street Business Improvement Districts Birmingham (UK), in which local stakeholders take the lead. We analyse the evolution of these regeneration processes by using two different manifestations of self-organization: autopoietic and dissipative self-organization. We found that a balanced interplay between autopoietic and dissipative self-organization of local stakeholders is important for vital urban regeneration processes to establish. We elaborate four explanatory conditions for this interplay. These conditions provide at the one hand stability and identity development, but also the needed connections with established actors and institutions around urban regeneration and flexibility to adjust to evolving demands during the process of regeneration. However, consolidation of such initiatives does mean a challenge for existing structures for the government, market and society that will need to adapt and change their roles to new governance realities. In this way self-organizing processes become meaningful in the regeneration of urban areas

Designing, Producing and Using Artifacts in the Structuration of Firm Knowledge: Evidence from Proprietary and Open Processes of Software Development.

In the paper we study the recursive nature of artifacts in the production and the socialization of organizational knowledge. In this respect, artifacts are interpreted both as the product (output) of organizational knowledge processes and, at the same time, as tools easing the development of other artifacts. We compare different practices of knowledge creation and diffusion in complex software production processes with the aim of understanding the effects of interplay between (1) coordination and control practices, (2) mediating artifacts and development tools, and (3) interactions between different actors in the development process. We aim at identifying the peculiar traits emerging in contrasting development paradigms, namely the closed, fully proprietary one widespread in the gaming console industry, and the open model of free/open source software development.video/computer game industry; artifacts; free/open source software; video game console

With the development of the industry and society, new verticals have emerged, such as Industry 4.0, cooperative sensing and augmented reality. These verticals require network robustness and availability, which forces the use of distributed domains to improve network scalability and resilience. To this aim, this paper proposes a new solution to distribute SDN domains by using Data Distribution Services (DDS). The DDS allows the exchange of network information, synchronization among controllers and auto-discovery. Moreover, it increases the control plane robustness, an important characteristic in 5G networks (e.g., if a controller fails, its resources and devices can be managed by other controllers in a short amount of time as they already know this information). To verify the effectiveness of the DDS, we design a testbed by integrating the DDS in SDN controllers and deploying these controllers in different regions of Spain. The communication among the controllers was evaluated in terms of latency and overhead.Postprint (author's final draft
