    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 ‘resist’ 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. “Rebuilding” 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 ”genres of use” explains some of the differential in approaches to Blackboard use. At a meta level, this process of creating “use” 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

    "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 ‘conflicting’ 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 (‘container’ or ‘itinerary’); [2] the EPR user (‘information-processer’ or ‘member of socio-technical network’); [3] organizational context (‘the setting within which the EPR is implemented’ or ‘the EPR-in-use’); [4] clinical work (‘decision-making’ or ‘situated practice’); [5] the process of change (‘the logic of determinism’ or ‘the logic of opposition’); [6] implementation success (‘objectively defined’ or ‘socially negotiated’); and [7] complexity and scale (‘the bigger the better’ or ‘small is beautiful’). 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 – 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 “Methodology to support self-transformation”, by focusing on ways of learning about governance for sustainability. Design/methodology/approach – It summarises core self-governance challenges for long-term sustainability, and the organisational capabilities required to face them, at the “Framework for Assessing Sustainable Governance”. 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 – 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 – 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 – 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 – 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 “Methodology for Self-Transformation”; 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

    Design Ltd.: Renovated Myths for the Development of Socially Embedded Technologies

    Full text link
    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. Randall, K. Schmidt, & V. Wulf (Eds.), Designing Socially Embedded Technologies: A European Challenge (2013, forthcoming) with the title "Building Socially Embedded Technologies: Implications on Design" within an EUSSET editorial initiative (www.eusset.eu/
