A requirements engineering framework for integrated systems development for the construction industry

Computer Integrated Construction (CIC) systems are computer environments through which collaborative working can be undertaken. Although many CIC systems have been developed to demonstrate the communication and collaboration within the construction projects, the uptake of CICs by the industry is still inadequate. This is mainly due to the fact that research methodologies of the CIC development projects are incomplete to bridge the technology transfer gap. Therefore, defining comprehensive methodologies for the development of these systems and their effective implementation on real construction projects is vital. Requirements Engineering (RE) can contribute to the effective uptake of these systems because it drives the systems development for the targeted audience. This paper proposes a requirements engineering approach for industry driven CIC systems development. While some CIC systems are investigated to build a broad and deep contextual knowledge in the area, the EU funded research project, DIVERCITY (Distributed Virtual Workspace for Enhancing Communication within the Construction Industry), is analysed as the main case study project because its requirements engineering approach has the potential to determine a framework for the adaptation of requirements engineering in order to contribute towards the uptake of CIC systems

A heuristic-based approach to code-smell detection

Encapsulation and data hiding are central tenets of the object oriented paradigm. Deciding what data and behaviour to form into a class and where to draw the line between its public and private details can make the difference between a class that is an understandable, flexible and reusable abstraction and one which is not. This decision is a difficult one and may easily result in poor encapsulation which can then have serious implications for a number of system qualities. It is often hard to identify such encapsulation problems within large software systems until they cause a maintenance problem (which is usually too late) and attempting to perform such analysis manually can also be tedious and error prone. Two of the common encapsulation problems that can arise as a consequence of this decomposition process are data classes and god classes. Typically, these two problems occur together – data classes are lacking in functionality that has typically been sucked into an over-complicated and domineering god class. This paper describes the architecture of a tool which automatically detects data and god classes that has been developed as a plug-in for the Eclipse IDE. The technique has been evaluated in a controlled study on two large open source systems which compare the tool results to similar work by Marinescu, who employs a metrics-based approach to detecting such features. The study provides some valuable insights into the strengths and weaknesses of the two approache

Findings from the Workshop on User-Centered Design of Language Archives

This white paper describes findings from the workshop on User-Centered Design of Language Archives organized in February 2016 by Christina Wasson (University of North Texas) and Gary Holton (University of Hawai‘i at Mānoa). It reviews relevant aspects of language archiving and user-centered design to construct the rationale for the workshop, relates key insights produced during the workshop, and outlines next steps in the larger research trajectory initiated by this workshop. The purpose of this white paper is to make all of the findings from the workshop publicly available in a short time frame, and without the constraints of a journal article concerning length, audience, format, and so forth. Selections from this white paper will be used in subsequent journal articles. So much was learned during the workshop; we wanted to provide a thorough documentation to ensure that none of the key insights would be lost. We consider this document a white paper because it provides the foundational insights and initial conceptual frameworks that will guide us in our further research on the user-centered design of language archives. We hope this report will be useful to members of all stakeholder groups seeking to develop user-centered designs for language archives.U.S. National Science Foundation Documenting Endangered Languages Program grants BCS-1543763 and BCS-1543828

Recognizing Co-Creators in Four Configurations: Critical Questions for Web Archiving

Four categories of co-creator shape web archivists\u27 practice and influence the development of web archives: social forces, users and uses, subjects of web archives, and technical agents. This paper illustrates how these categories of co-creator overlap and interact in four specific web archiving contexts. It recommends that web archivists acknowledge this complex array of contributors as a way to imagine web archives differently. A critical approach to web archiving recognizes relationships and blended roles among stakeholders; seeks opportunities for non-extractive archival activity; and acknowledges the value of creative reuse as an important aspect of preservation

Recording, Documentation, and Information Management for the Conservation of Heritage Places: Guiding Principles

Provides guidance on integrating recording, documentation, and information management of territories, sites, groups of buildings, or monuments into the conservation process; evaluating proposals; consulting specialists; and controlling implementation

Don’t Look Back: The Paradoxical Role of Recording in the Fashion Design Process

Although there is little systematic research in academia or industry examining design processes in Fashion, anecdotal evidence, based on self- reports and observations, suggests that designers very rarely record the process of designing. Conversely, benefits and requirements of recording the design process within other domains, such as Engineering and Architecture, are well supported in the literature. This paper attempts to explore the dichotomy of recording and non-recording practice across these fields through a review of the literature, semi-structured interviews and a report on one case study in particular, drawing out further detail. Commonalities and differences are identified and new directions for research proposed

Long-Term Preservation of Digital Records, Part I: A Theoretical Basis

The Information Revolution is making preservation of digital records an urgent issue. Archivists have grappled with the question of how to achieve this for about 15 years. We focus on limitations to preservation, identifying precisely what can be preserved and what cannot. Our answer comes from the philosophical theory of knowledge, especially its discussion about the limits of what can be communicated. Philosophers have taught that answers to critical questions have been obscured by "failure to understand the logic of our language". We can clarify difficulties by paying extremely close attention to the meaning of words such as 'knowledge', 'information', 'the original', and 'dynamic'. What is valuable in transmitted and stored messages, and what should be preserved, is an abstraction, the pattern inherent in each transmitted and stored digital record. This answer has, in fact, been lurking just below the surface of archival literature. To make progress, archivists must collaborate with software engineers. Understanding perspectives across disciplinary boundaries will be needed.
