    This research focuses on tools that support the development of tangible interaction-based applications for distributed computing environments. Applications built with these tools are capable of utilizing heterogeneous resources for tangible interaction and can be reconfigured for different contexts with minimal code changes. Current trends in computing, especially in areas such as computational science, scientific visualization and computer supported collaborative work, foreshadow increasing complexity, distribution and remoteness of computation and data. These trends imply that tangible interface developers must address concerns of both tangible interaction design and networked distributed computing. In this dissertation, we present a software architecture that supports separation of these concerns. Additionally, a tangibles-based software development toolkit based on this architecture is presented that enables the logic of elements within a tangible user interface to be mapped to configurations that vary in the number, type and location of resources within a given tangibles-based system

    Communicating soil carbon science to farmers: incorporating credibility, salience and legitimacy

    Get PDF
    A key narrative within climate change science is that conserving and improving soil carbon through agricultural practices can contribute to agricultural productivity and is a promising option for mitigating carbon loss through sequestration. This paper examines the potential disconnect between science and practice in the context of communicating information about soil carbon management. It focuses on the information producing process and on stakeholder (adviser, farmer representative, policy maker etc) assessment of the attributes credibility, salience and legitimacy. In doing this it draws on results from consultations with stakeholders in the SmartSOIL project which aimed to provide decision support guidelines about practices that optimise carbon mitigation and crop productivity. An iterative methodology, used to engage stakeholders in developing, testing and validating a range of decision support guidelines in six case study regions across Europe, is described. This process enhanced legitimacy and revealed the importance, and the different dimensions, of stakeholder views on credibility and salience. The results also highlight the complexities and contested nature of managing soil carbon. Some insights are gained into how to achieve more effective communication about soil carbon management, including the need to provide opportunities in projects and research programmes for dialogue to engender better understanding between science and practice

    School principals are responsible for developing a leadership culture within their buildings (Bass, 1995; Bass & Riggio, 2006). This single-case, multi-site study explored the perceptions of principals and teacher leaders on the use of transformational practices to cultivate a teacher leadership pipeline. Transformational leadership theory framed the study to examine the influence on principals\u27 use of transformational practices to set the vision, inspire others through role model behaviors, guide the work of innovative teams and programs, and build capacity in others (Bass, 1995; Bass & Riggio, 2006). Sample selection of three high schools with five-star climate ratings provided the multiple locations for this single-case study. A total of nine participants included the principal and two teacher leaders from each of the selected sites within the same school district located in the Southeast. Data was gathered through interviews, observations of participant-led meetings, and a review of documents, and analyzed for thematic connections to the four pillars of transformational leadership theory: a) idealized influence, b) inspirational motivation, c) intellectual stimulation, and d) individualized consideration (Bass, 1995; Bass & Riggio, 2006). Findings from the study supported how principals utilized transformational leadership principal practices to foster a teacher leadership pipeline through shared vision setting, sustaining influential relationships, and shaping a leadership performance culture. Conclusions integrated recommendations for the evolution of the leadership pipeline, as follows: a) using the professional learning community model to share leadership power, b) incorporating perception surveys to monitor for a leadership culture, and c) rethinking human resource actions through the lens of teacher leaders. Implications and future suggestions for educational research centered on quantitatively exploring leadership practices, employee engagement, and teacher leadership development through the lens of the transformational leadership framework

    Empowerment or Engagement? Digital Health Technologies for Mental Healthcare

    Get PDF
    We argue that while digital health technologies (e.g. artificial intelligence, smartphones, and virtual reality) present significant opportunities for improving the delivery of healthcare, key concepts that are used to evaluate and understand their impact can obscure significant ethical issues related to patient engagement and experience. Specifically, we focus on the concept of empowerment and ask whether it is adequate for addressing some significant ethical concerns that relate to digital health technologies for mental healthcare. We frame these concerns using five key ethical principles for AI ethics (i.e. autonomy, beneficence, non-maleficence, justice, and explicability), which have their roots in the bioethical literature, in order to critically evaluate the role that digital health technologies will have in the future of digital healthcare

    Negotiating disciplinary boundaries in engineering problem-solving practice

    Get PDF
    Includes bibliographical referencesThe impetus for this research is the well-documented current inability of Higher Education to facilitate the level of problem solving required in 21st century engineering practice. The research contends that there is insufficient understanding of the nature of and relationship between the significantly different forms of disciplinary knowledge underpinning engineering practice. Situated in the Sociology of Education, and drawing on the social realist concepts of knowledge structures (Bernstein, 2000) and epistemic relations (Maton, 2014), the research maps the topology of engineering problem-solving practice in order to illuminate how novice problem solvers engage in epistemic code shifting in different industrial contexts. The aim in mapping problem-solving practices from an epistemological perspective is to make an empirical contribution to rethinking the theory/practice relationship in multidisciplinary engineering curricula and pedagogy, particularly at the level of technician. A novel and pragmatic problem-solving model - integrated from a range of disciplines - forms the organising framework for a methodologically pluralist case-study approach. The research design draws on a metaphor from the empirical site (modular automation systems) and sees the analysis of twelve matched cases in three categories. Case-study data consist of questionnaire texts, re-enactment interviews, expert verification interviews, and industry literature. The problem-solving model components (problem solver, problem environment, problem structure and problem-solving process) were analysed using, primarily, the Legitimation Code Theory concept of epistemic relations. This is a Cartesian plane-based instrument describing the nature of and relations between a phenomenon (what) and ways of approaching the phenomenon (how). Data analyses are presented as graphical relational maps of different practitioner knowledge practices in different contexts across three problem solving stages: approach, analysis and synthesis. Key findings demonstrate a symbiotic, structuring relationship between the 'what' and the 'how' of the problem in relation to the problem-solving components. Successful problem solving relies on the recognition of these relationships and the realisation of appropriate practice code conventions, as held to be legitimate both epistemologically and contextually. Successful practitioners engage in explicit code-shifting, generally drawing on a priori physics and mathematics-based knowledge, while acquiring a posteriori context-specific logic-based knowledge. High-achieving practitioners across these disciplinary domains demonstrate iterative code-shifting practices and discursive sensitivity. Recommendations for engineering education include the valuing of disciplinary differences and the acknowledgement of contextual complexity. It is suggested that the nature of engineering mathematics as currently taught and the role of mathematical thinking in enabling successful engineering problem-solving practice be investigated

    Application of an Organizational Evaluation Capacity Assessment in a Multinational NGO: A Case Study to Support Applied Practice

    Get PDF
    As evaluation capacity building (ECB) has rapidly emerged as a practice in human service organizations and as a field of academic inquiry, attention has focused on methods of evaluation capacity building while assessment of organizational evaluation capacity (EC) has lagged behind. To examine the practice of organizational evaluation capacity assessment, this dissertation presents two separate but related studies. In sub-study 1, I present a qualitative evidence synthesis of the research theorizing organizational evaluation capacity models. In sub-study 2, I support the implementation of one of the tools from the evidence-synthesis at a multinational human service organization. I use a concurrent mixed methods instrumental case study to describe how the sample organization implements an evaluation capacity assessment survey, interprets the results, and determines the next course of action in their evaluation capacity building initiatives. In the conclusion, I discuss the two sub-studies and use the lessons and observations from the case study to theorize an application framework for organizational evaluation capacity assessments

    Participatory design for behaviour change: an integrative approach to improving healthcare practice focused on staff participation

    Get PDF
    This thesis explores the application of participatory design and behaviour change in the process of planning and developing quality and safety improvement interventions within the hospital environment. This focus is examined through the empirical investigation of a real-life improvement process, looking at the diagnosis and management of Urinary Tract Infection (UTI) in older adults within the busy environment of an Emergency Department.A review of the literature helped identify that, whilst a behavioural approach to healthcare has been employed with some measured success at a public health level, its application at the healthcare service level has been less explored and studied. Furthermore, there has been an acknowledged necessity to better integrate stakeholder engagement in behaviour change interventions, but such integration is underplayed and underexplored by current frameworks.A comprehensive participatory action research project – encompassing workshops, focus groups, interviews, meetings and digital communication led and facilitated by the researcher – was conducted with the engagement of over fifty staff, including nurses, doctors, managers, pharmacists and microbiologists working in various departments of a large NHS University Hospital in the East Midlands region of the UK. The improvement project followed the stepwise process of the Behaviour Change Wheel framework, while also observing the premises and principles of stakeholder participation, put forth by participatory design practice. The research resulted in an original integrative approach, which developed from the work involving researcher and stakeholders in a process of cyclical reflection-in-action. This iterative process facilitated the recognition of specific ways whereby staff wanted to and could be involved throughout the intervention; it also led to the adaptation of selected tools and the incorporation of new tools tailored to the expertise, preferences and priorities sought by the group of stakeholders.Collectively, the study findings identified the need for a new behaviour change support framework for participatory use. Likewise, they also indicate that the degree of stakeholder engagement normally expected from a participatory design process is often not feasible – and sometimes, not wanted – within the hospital context. Healthcare professionals have time limitations that need to be respected and the rationale for participation should follow real, rather than ideal possibilities of engagement. The findings led to the identification of specific recommendations that should be considered when looking at the advantages and disadvantages, facilitators and barriers, motivations, and hierarchical issues of involving healthcare staff in participatory quality improvement projects.Finally, this thesis proposes an original approach – the Participatory Design for Behaviour Change framework – which integrates behavioural theory, models and tools, with participatory principles and methods. The framework underwent various iterations, and a final validation with a group of qualified healthcare professionals who had not taken part in the original intervention process. Opportunities for further research are presented to evaluate the applicability and effectiveness of the proposed framework within similar healthcare contexts, especially in comparison with existing alternative approaches.</div

    One of the key elements of the SERC’s research strategy is transforming the practice of systems engineering – “SE Transformation.” The Grand Challenge goal for SE Transformation is to transform the DoD community’s current systems engineering and management methods, processes, and tools (MPTs) and practices away from sequential, single stovepipe system, hardware-first, outside-in, document-driven, point-solution, acquisition-oriented approaches; and toward concurrent, portfolio and enterprise-oriented, hardware-software-human engineered, balanced outside-in and inside-out, model-driven, set-based, full life cycle approaches.This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)) under Contract H98230-08- D-0171 (Task Order 0031, RT 046).This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)) under Contract H98230-08- D-0171 (Task Order 0031, RT 046)

    An inquiry into the nature of effective dialogue and discourse and peacebuilding through leadership

    Get PDF
    The research study and findings presented in this work underscore the necessity to design and develop effective strategies for inter-paradigm dialogue and discourse for peacebuilding. The study argues that adoption and application of appropriate dialogue strategies impact and engender the nurturing and emergence of a culture of leadership that can foster sustainable peace. Dialogue and discourse processes are considered as being intricately connected to processes of conflict transformation and resolution, and linkages of dialogue, peacebuilding and leadership are mirrored in macro- and micro- spaces of engagement, namely, much contested cultural, political and economic spaces in which myriad and diverse perspectives reside. The potential for peace, it is argued, substantially lies in the formulation and design of contextually-relevant frameworks for equitable and sustainable socio-economic development, and macro-micro intersections play themselves out in the dialogue field within which societies and individuals can seek and strive to anticipate, accommodate, attain and enact their life wisdoms into peaceful systems of co-existence. This view also speaks to the issue of how consensual and sustainable global and regional collaborative enterprise requires the parallel accompaniment of well-configured partnerships in support of cultural responsiveness and social cohesion. Through discussion of appropriate methodologies of dialogue and discourse, the identification and statement of objectives for this study, as well as the design, elaboration and configuration of its research framework, aimed to contribute towards furthering debate surrounding the integration of prevailing theoretical approaches, in order to gain a better understanding of the linkages and dynamics between peacebuilding initiatives, conflict resolution processes, and effective and sustainable leadership. Dialogue is adopted as the key component in the design of an effective model and architecture for peace building. The enquiry underscores emerging gaps that require addressing, and which may then highlight zones of ambiguity, or dialectics between action and practice, and between researcher and practitioner
