Between 'technological obduracy' and 'academic resistance': concepts of use of blackboard and the experience of university teachers.
Until recently, Blackboard has been one of the most common forms of learning-management systems (LMSs) in use in Australian universities. However, it has been adopted and used by academics far less than its proponents had anticipated. The literature of academic use of learning-management systems paints a picture, either of a relatively straightforward understanding of adoption of new educational technologies as an informational problem, or alternatively, of problematic academics who âresistâ using Blackboard. Academics themselves can understand the technology of Blackboard to be obdurate, time consuming and difficult to use. Drawing on a combination of sensemaking theory, practice theory and the socio-technical theories of social construction of technology and actor network theory, I ask how academics have set about using Blackboard. I clarify how educational technology use in the literature is constructed from diverse perspectives and how users in practice negotiate their way through Blackboard at four levels of encounter: as material infrastructure; as a process of orientation to, and reading of, navigational and interface symbolism; as an individual sensemaking project about representing education; and as an organisational representation and a technical system. Each level contains capacities for disruption and rebuilding of former habits and sense. âRebuildingâ a new interpretation and an effective use of Blackboard by any individual academic is never certain, as at each level different strategies are required, but rebuilding a notion of technologised education by creating âgenres of useâ explains some of the differential in approaches to Blackboard use. At a meta level, this process of creating âuseâ also elucidates theories of action, practice and social change in practice theory and to a lesser extent in social construction of technology and actor network theory, by adding the insights of sensemaking theory to show how academics build their own concepts of use in an LMS, that can appear obdurate and unwieldy to users. The theoretical purpose is to offer an essay in understanding the processes of socio-technical change where change is not necessarily fostered by technological ease or user self-motivation
The development of secure and usable systems.
"People are the weakest link in the security chain"---Bruce Schneier. The aim of the thesis is to investigate the process of designing secure systems, and how designers can ensure that security mechanisms are usable and effective in practice. The research perspective is one of security as a socio-technical system. A review of the literature of security design and Human Computer Interactions in Security (HCISec) reveals that most security design methods adopt either an organisational approach, or a technical focus. And whilst HCISec has identified the need to improve usability in computer security, most of the current research in this area is addressing the issue by improving user interfaces to security tools. Whilst this should help to reduce users' errors and workload, this approach does not address problems which arise from the difficulty of reconciling technical requirements and human factors. To date, little research has been applied to socio-technical approaches to secure system design methods. Both identifying successful socio-technical design approaches and gaining a better understanding of the issues surrounding their application is required to address this gap. Appropriate and Effective Guidance for Information Security (AEGIS) is a socio-technical secure system development methodology developed for this purpose. It takes a risk-based approach to security design and focuses on recreating the contextual information surrounding the system in order to better inform security decisions, with the aim of making these decisions better suited to users' needs. AEGIS uses a graphical notation defined in the UML Meta-Object Facility to provide designers with a familiar and well- supported means of building models. Grid applications were selected as the area in which to apply and validate AEGIS. Using the research methodology Action Research, AEGIS was applied to a total of four Grid case studies. This allowed in the first instance the evaluation and refinement of AEGIS on real- world systems. Through the use of the qualitative data analysis methodology Grounded Theory, the design session transcripts gathered from the Action Research application of AEGIS were then further analysed. The resulting analysis identified important factors affecting the design process - separated into categories of responsibility, motivation, stakeholders and communication. These categories were then assembled into a model informing the factors and issues that affect socio-technical secure system design. This model therefore provides a key theoretical insight into real-world issues and is a useful foundation for improving current practice and future socio-technical secure system design methodologies
Tensions and paradoxes in electronic patient record research: a systematic literature review using the meta-narrative method
Background: The extensive and rapidly expanding research literature on electronic patient records (EPRs) presents challenges to systematic reviewers. This literature is heterogeneous and at times conflicting, not least because it covers multiple research traditions with different underlying philosophical assumptions and methodological approaches.
Aim: To map, interpret and critique the range of concepts, theories, methods and empirical findings on EPRs, with a particular emphasis on the implementation and use of EPR systems.
Method: Using the meta-narrative method of systematic review, and applying search strategies that took us beyond the Medline-indexed literature, we identified over 500 full-text sources. We used âconflictingâ findings to address higher-order questions about how the EPR and its implementation were differently conceptualised and studied by different communities of researchers.
Main findings: Our final synthesis included 24 previous systematic reviews and 94 additional primary studies, most of the latter from outside the biomedical literature. A number of tensions were evident, particularly in relation to: [1] the EPR (âcontainerâ or âitineraryâ); [2] the EPR user (âinformation-processerâ or âmember of socio-technical networkâ); [3] organizational context (âthe setting within which the EPR is implementedâ or âthe EPR-in-useâ); [4] clinical work (âdecision-makingâ or âsituated practiceâ); [5] the process of change (âthe logic of determinismâ or âthe logic of oppositionâ); [6] implementation success (âobjectively definedâ or âsocially negotiatedâ); and [7] complexity and scale (âthe bigger the betterâ or âsmall is beautifulâ). Findings suggest that integration of EPRs will always require human work to re-contextualize knowledge for different uses; that whilst secondary work (audit, research, billing) may be made more efficient by the EPR, primary clinical work may be made less efficient; that paper, far from being technologically obsolete, currently offers greater ecological flexibility than most forms of electronic record; and that smaller systems may sometimes be more efficient and effective than larger ones.
Conclusions: The tensions and paradoxes revealed in this study extend and challenge previous reviews and suggest that the evidence base for some EPR programs is more limited than is often assumed. We offer this paper as a preliminary contribution to a much-needed debate on this evidence and its implications, and suggest avenues for new research
Governance for sustainability: learning from VSM practice
Purpose â While there is some agreement on the usefulness of systems and complexity approaches to tackle the sustainability challenges facing the organisations and governments in the twenty-first century, less is clear regarding the way such approaches can inspire new ways of governance for sustainability. The purpose of this paper is to progress ongoing research using the Viable System Model (VSM) as a meta-language to facilitate long-term sustainability in business, communities and societies, using the âMethodology to support self-transformationâ, by focusing on ways of learning about governance for sustainability. Design/methodology/approach â It summarises core self-governance challenges for long-term sustainability, and the organisational capabilities required to face them, at the âFramework for Assessing Sustainable Governanceâ. This tool is then used to analyse capabilities for governance for sustainability at three real situations where the mentioned Methodology inspired bottom up processes of self-organisation. It analyses the transformations decided from each organisation, in terms of capabilities for sustainable governance, using the suggested Framework. Findings â Core technical lessons learned from using the framework are discussed, include the usefulness of using a unified language and tool when studying governance for sustainability in differing types and scales of case study organisations. Research limitations/implications â As with other exploratory research, it reckons the convenience for further development and testing of the proposed tools to improve their reliability and robustness. Practical implications â A final conclusion suggests that the suggested tools offer a useful heuristic path to learn about governance for sustainability, from a VSM perspective; the learning from each organisational self-transformation regarding governance for sustainability is insightful for policy and strategy design and evaluation; in particular the possibility of comparing situations from different scales and types of organisations. Originality/value â There is very little coherence in the governance literature and the field of governance for sustainability is an emerging field. This piece of exploratory research is valuable as it presents an effective tool to learn about governance for sustainability, based in the âMethodology for Self-Transformationâ; and offers reflexions on applications of the methodology and the tool, that contribute to clarify the meaning of governance for sustainability in practice, in organisations from different scales and types

Complex systems science: expert consultation report
Executive SummaryA new programme of research in Complex Systems Science must be initiated by FETThe science of complex systems (CS) is essential to establish rigorous scientific principles on which to develop the future ICT systems that are critical to the well-being, safety and prosperity of Europe and its citizens. As the âICT incubator and pathfinder for new ideas and themes for long-term research in the area of information and communication technologiesâ FET must initiate a significant new programme of research in complex systems science to underpin research and development in ICT. Complex Systems Science is a âblue skyâ research laboratory for R&D in ICT and their applications. In July 2009, ASSYST was given a set of probing questions concerning FET funding for ICT-related complex systems research. This document is based on the CS communityâs response.Complex systems research has made considerable progress and is delivering new scienceSince FET began supporting CS research, considerable progress has been made. Building on previous understanding of concepts such as emergence from interactions, far-from-equilibrium systems, border of chaos and self-organised criticality, recent CS research is now delivering rigorous theory through methods of statistical physics, network theory, and computer simulation. CS research increasingly demands high-throughput data streams and new ICT-based methods of observing and reconstructing, i.e. modelling, the dynamics from those data in areas as diverse as embryogenesis, neuroscience, transport, epidemics, linguistics, meteorology, and robotics. CS research is also beginning to address the problem of engineering robust systems of systems of systems that can adapt to changing environments, including the perplexing problem that ICT systems are too often fragile and non-adaptive.Recommendation: A Programme of Research in Complex Systems Science to Support ICTFundamental theory in Complex Systems Science is needed, but this can only be achieved through real-world applications involving large, heterogeneous, and messy data sets, including people and organisations. A long-term vision is needed. Realistic targets can be set. Fundamental research can be ensured by requiring that teams include mathematicians, computer scientists, physicists and computational social scientists.One research priority is to develop a formalism for multilevel systems of systems of systems, applicable to all areas including biology, economics, security, transportation, robotics, health, agriculture, ecology, and climate change. Another related research priority is a scientific perspective on the integration of the new science with policy and its implementation, including ethical problems related to privacy and equality.A further priority is the need for education in complex systems science. Conventional education continues to be domain-dominated, producing scientists who are for the most part still lacking fundamental knowledge in core areas of mathematics, computation, statistical physics, and social systems. Therefore:1. We recommend that FET fund a new programme of work in complex systems science as essential research for progress in the development of new kinds of ICT systems.2. We have identified the dynamics of multilevel systems as the area in complex systems science requiring a major paradigm shift, beyond which significant scientific progress cannot be made.3. We propose a call requiring: fundamental research in complex systems science; new mathematical and computational formalisms to be developed; involving a large âguinea pigâ organisation; research into policy and its meta-level information dynamics; and that all research staff have interdisciplinary knowledge through an education programme.Tangible outcomes, potential users of the new science, its impact and measures of successUsers include (i) the private and public sectors using ICT to manage complex systems and (ii) researchers in ICT, CSS, and all complex domains. The tangible output of a call will be new knowledge on the nature of complex systems in general, new knowledge of the particular complex system(s) studied, and new knowledge of the fundamental role played by ICT in the research and implementation to create real systems addressing real-world problems. The impact of the call will be seen through new high added-value opportunities in the public and private sectors, new high added-value ICT technologies, and new high added-value science to support innovation in ICT research and development. The measure of success will be through the delivery of these high added-value outcomes, and new science to better understand failures
Design Ltd.: Renovated Myths for the Development of Socially Embedded Technologies
This paper argues that traditional and mainstream mythologies, which have
been continually told within the Information Technology domain among designers
and advocators of conceptual modelling since the 1960s in different fields of
computing sciences, could now be renovated or substituted in the mould of more
recent discourses about performativity, complexity and end-user creativity that
have been constructed across different fields in the meanwhile. In the paper,
it is submitted that these discourses could motivate IT professionals in
undertaking alternative approaches toward the co-construction of
socio-technical systems, i.e., social settings where humans cooperate to reach
common goals by means of mediating computational tools. The authors advocate
further discussion about and consolidation of some concepts in design research,
design practice and more generally Information Technology (IT) development,
like those of: task-artifact entanglement, universatility (sic) of End-User
Development (EUD) environments, bricolant/bricoleur end-user, logic of
bricolage, maieuta-designers (sic), and laissez-faire method to socio-technical
construction. Points backing these and similar concepts are made to promote
further discussion on the need to rethink the main assumptions underlying IT
design and development some fifty years later the coming of age of software and
modern IT in the organizational domain.Comment: This is the peer-unreviewed of a manuscript that is to appear in D.
