National innovation systems, developing countries, and the role of intermediaries: a critical review of the literature

Developed over the past three decades, the national innovation system concept (NIS) has been widely used by both scholars and policy makers to explain how interactions between a set of distinct, nationally bounded institutions supports and facilitates technological change and the emergence and diffusion of new innovations. This concept provides a framework by which developing countries can adopt for purposes of catching up. Initially conceived on structures and interactions identified in economically advanced countries, the application of the NIS concept to developing countries has been gradual and has coincided – in the NIS literature – with a move away from overly macro-interpretations to an emphasis on micro-level interactions and processes, with much of this work questioning the nation state as the most appropriate level of analysis, as well as the emergence of certain intermediary actors thought to facilitate knowledge exchange between actors and institutions. This paper reviews the NIS literature chronologically, showing how this shift in emphasis has diminished somewhat the importance of both institutions, particularly governments, and the process of institutional capacity building. In doing so, the paper suggests that more recent literature on intermediaries such as industry associations may offer valuable insights to how institutional capacity building occurs and how it might be directed, particularly in the context of developing countries where governance capacities are often lacking, contributing to less effective innovation systems, stagnant economies, and unequal development

From Social Simulation to Integrative System Design

As the recent financial crisis showed, today there is a strong need to gain "ecological perspective" of all relevant interactions in socio-economic-techno-environmental systems. For this, we suggested to set-up a network of Centers for integrative systems design, which shall be able to run all potentially relevant scenarios, identify causality chains, explore feedback and cascading effects for a number of model variants, and determine the reliability of their implications (given the validity of the underlying models). They will be able to detect possible negative side effect of policy decisions, before they occur. The Centers belonging to this network of Integrative Systems Design Centers would be focused on a particular field, but they would be part of an attempt to eventually cover all relevant areas of society and economy and integrate them within a "Living Earth Simulator". The results of all research activities of such Centers would be turned into informative input for political Decision Arenas. For example, Crisis Observatories (for financial instabilities, shortages of resources, environmental change, conflict, spreading of diseases, etc.) would be connected with such Decision Arenas for the purpose of visualization, in order to make complex interdependencies understandable to scientists, decision-makers, and the general public.Comment: 34 pages, Visioneer White Paper, see http://www.visioneer.ethz.c

3D-in-2D Displays for ATC.

This paper reports on the efforts and accomplishments of the 3D-in-2D Displays for ATC project at the end of Year 1. We describe the invention of 10 novel 3D/2D visualisations that were mostly implemented in the Augmented Reality ARToolkit. These prototype implementations of visualisation and interaction elements can be viewed on the accompanying video. We have identified six candidate design concepts which we will further research and develop. These designs correspond with the early feasibility studies stage of maturity as defined by the NASA Technology Readiness Level framework. We developed the Combination Display Framework from a review of the literature, and used it for analysing display designs in terms of display technique used and how they are combined. The insights we gained from this framework then guided our inventions and the human-centered innovation process we use to iteratively invent. Our designs are based on an understanding of user work practices. We also developed a simple ATC simulator that we used for rapid experimentation and evaluation of design ideas. We expect that if this project continues, the effort in Year 2 and 3 will be focus on maturing the concepts and employment in a operational laboratory settings

Analysis Of Aircraft Arrival Delay And Airport On-time Performance

While existing grid environments cater to specific needs of a particular user community, we need to go beyond them and consider general-purpose large-scale distributed systems consisting of large collections of heterogeneous computers and communication systems shared by a large user population with very diverse requirements. Coordination, matchmaking, and resource allocation are among the essential functions of large-scale distributed systems. Although deterministic approaches for coordination, matchmaking, and resource allocation have been well studied, they are not suitable for large-scale distributed systems due to the large-scale, the autonomy, and the dynamics of the systems. We have to seek for nondeterministic solutions for large-scale distributed systems. In this dissertation we describe our work on a coordination service, a matchmaking service, and a macro-economic resource allocation model for large-scale distributed systems. The coordination service coordinates the execution of complex tasks in a dynamic environment, the matchmaking service supports finding the appropriate resources for users, and the macro-economic resource allocation model allows a broker to mediate resource providers who want to maximize their revenues and resource consumers who want to get the best resources at the lowest possible price, with some global objectives, e.g., to maximize the resource utilization of the system

Integrated decision-support framework for sustainable fleet implementation

Issues regarding fossil fuel depletion, climate change and air pollution associated with motorised urban transportation have motivated intensive research to find cleaner, greener, and energy-efficient alternative fuels. Alternative fuel vehicles have a pivotal role in moving towards a sustainable future, with many already deployed as public transport fleet. Unlike private vehicles, the process of evaluating and selecting the appropriate fuel technology for the taxi fleet, for instance, can be demanding due to the involvement of stakeholders with different, often conflicting objectives. While many life cycle models have been developed as decision-support tools for evaluating vehicle technologies and fuel pathways based on multiple criteria, the different perspectives of fleet operators, policymakers and vehicle manufacturers may create a barrier towards the adoption of eco-friendly low carbon fleet. At present, the search for one optimal solution that performs the best in all aspects is difficult to achieve in practice. Therefore, there is a need for an integrated tool that can align the different priorities of economic, environmental and social perspectives of decision makers. This research aims to develop a computer-based framework that can be used as a shared justification tool to support multi-stakeholder decision making. The main contribution is the implementation and applicability testing of the framework via a probabilistic life cycle analysis with satisficing model. The model was initially tested and evaluated by representative third-party users from the transport industry. When demonstrated in an illustrative taxi case study, results from the life cycle analysis show constant compensation and trade-offs between the criteria. Subsequently, this thesis provides an example of how the satisficing choice model seeks a satisfactory solution that adequately meets the multiple objectives of decision makers. Also, the research provides insights for other research and industry efforts in developing tools to support decision making towards sustainable development practices

Spoken and embodied interaction in facilitated computer-supported workplace meetings

Almost 25 years ago, Clawson, Bostrom, and Anson (1993) drew attention to the fact that the ability to facilitate diverse human and technological interactions will be one of the most essential skills for leading and contributing to all levels of the organization in the future (p. 547). Today, there is an increased interest in studying facilitated meetings, wherein facilitation is most commonly understood as the process of helping groups work effectively to accomplish shared outcomes. Nevertheless, little of the existing research has provided empirically-grounded insights into the practice of facilitation. This thesis aims to close this gap by means of providing a detailed analysis of how facilitators go about doing facilitation work in facilitated computer-supported workplace meetings. The data comprise 53 hours of audio- and video-recorded multi-party interactions among facilitator(s) and participants, occurring during facilitated meetings in a business setting. The data were analysed using conversation analysis to examine the talk and embodied conduct of facilitators and meeting participants, as these unfold sequentially. The first analytic chapter reveals the macro-organization of the facilitated meetings, and it contrasts the practice view with the theoretical approach towards the organization of the facilitated meetings. The second analytic chapter investigates the interactional practices used by the facilitators to unpack participation that has already been elicited, captured, and displayed graphically on the public screen via the use of technology. In the third analytic chapter, I explore how the facilitators use computer software to build visual representations of the participants contributions. In the final analytic chapter, I investigate the practices of decision-making in meeting settings with multiple participants. Overall, this thesis makes innovative contributions to our understanding of the practice of facilitated computer-supported workplace meetings. It challenges existing literature on facilitation by finding that facilitators can orchestrate participant input, questioning the facilitator s role as content-neutral , as proposed by leading practitioners in the field of facilitation (e.g., Kaner et al., 2014). At the same time, it shows how the manipulation of computer software is an accountable action and how the decision-making process occasions or constrains the production of alignment between participant(s) and facilitator(s). The thesis also contributes to conversation analytic research on questioning, as well as the action of unpacking participation. I show that the notion that open-ended questions better elicit participation than interrogatives is generally not supported empirically, at least in this context. The thesis contributes to existing literature on multi-party meeting interaction, showing how the departure from the canonical next-speaker selection technique which involves the use of address terms and address positions in an utterance takes place. Further, it enhances our understanding of how computer software constrains and/or affords progressivity in interaction. In this sense, I enhance our understanding of the concept of agency of artefacts. Finally, I contribute to knowledge on group decision-making, an under-researched yet core activity in facilitated and other types of meetings. Here, I contribute to the body of work on the interplay between deontics and epistemics in interaction. This thesis shows the applicability of conversation analysis to the study of facilitation. By analysing talk and embodied conduct, communicative practices for accomplishing successful facilitated meetings are revealed and these should be of core interest to both professional and novice facilitators

Dynamic capabilities in complex projects: the case of London Heathrow terminal 5

Whereas existing approaches and empirical studies of dynamic capabilities focus on the strategic innovation activities of firms (i.e., permanent organizations executing multiple projects and programs), this article identifies how certain types of dynamic capabilities are required to deliver large, complex, and risky projects involving multiple parties. Our longitudinal study of the design and construction of Heathrow Airport Terminal 5 by the British Airports Authority (BAA) makes three main contributions to the literature: (1) It contributes to the project management literature by identifying how specific dynamic capabilities (BAA's "T5 Agreement," strategic behaviors, and collaborative processes) are developed through a three-phase process (learning, codifying, and mobilizing) to support the strategic management of complex projects. (2) While emphasizing their importance for the successful management of complex projects, our findings also underline the continuing fragility of dynamic capabilities. (3) The case study reveals their fluidity and balancing role with respect to demands for stability and change in complex, uncertain, and volatile project environments

Recruiting IT Faculty

The current shortage of qualified IT professionals in industry now extends to academia. Academic departments need a systematic approach to recruit new IT faculty effectively. This process is hindered not only by the shortage of formally qualified PhDs, but also by the lack of consensus in the definition of IT and the competition with industry for skilled professionals, even at the PhD level. Another challenge is the gap between new PhDs seeking research positions and the shortage of qualified faculty in institutions for which teaching is a priority. This tutorial explores these and other issues related to IT faculty recruiting, and provides a systematic and practical methodology for pro-actively attracting the right people to the right places in academia. An effective recruiting process requires thoughtful problem definition, identification of appropriate sources of alternatives, consistency and fairness in selection using well-defined criteria, and aggressive closure
