    Progress in many domains increasingly benefits from our ability to view the systems through a computational lens, i.e., using computational abstractions of the domains; and our ability to acquire, share, integrate, and analyze disparate types of data. These advances would not be possible without the advanced data and computational cyberinfrastructure and tools for data capture, integration, analysis, modeling, and simulation. However, despite, and perhaps because of, advances in "big data" technologies for data acquisition, management and analytics, the other largely manual, and labor-intensive aspects of the decision making process, e.g., formulating questions, designing studies, organizing, curating, connecting, correlating and integrating crossdomain data, drawing inferences and interpreting results, have become the rate-limiting steps to progress. Advancing the capability and capacity for evidence-based improvements in science, engineering, and public policy requires support for (1) computational abstractions of the relevant domains coupled with computational methods and tools for their analysis, synthesis, simulation, visualization, sharing, and integration; (2) cognitive tools that leverage and extend the reach of human intellect, and partner with humans on all aspects of the activity; (3) nimble and trustworthy data cyber-infrastructures that connect, manage a variety of instruments, multiple interrelated data types and associated metadata, data representations, processes, protocols and workflows; and enforce applicable security and data access and use policies; and (4) organizational and social structures and processes for collaborative and coordinated activity across disciplinary and institutional boundaries.Comment: A Computing Community Consortium (CCC) white paper, 9 pages. arXiv admin note: text overlap with arXiv:1604.0200

    Technology-Enhanced Learning (TEL) tools to improve computational thinking skills

    The common and easy access to technological devices has led to the rapid inclusion of technology into the learning process. The development of technical skills, as well as the increasing confidence in computer attitudes, seems to be obvious. We therefore propose to go beyond and advocate the use of TEL to provide specific leadership, multi-tasking and other organizational skills, known as computational thinking, as precisely the main contributions provided by TEL. To support this hypothesis, we present two different experiences. The first, based on high-school students, to introduce young people to technology at the same time as they acquire other demanding skills. The second, with undergraduate Computer Science students, is focused on technology itself to enhance and improve computational thinking skills. A comparison is also made between two populations with different digital profiles in their user skills (general in the first case and engineering biased in the second).Peer ReviewedPostprint (author’s final draft

    Dynamics of organizational culture: Individual beliefs vs. social conformity

    Get PDF
    The complex nature of organizational culture challenges our ability to infers its underlying dynamics from observational studies. Recent computational studies have adopted a distinct different view, where plausible mechanisms are proposed to describe a wide range of social phenomena, including the onset and evolution of organizational culture. In this spirit, this work introduces an empirically-grounded, agent-based model which relaxes a set of assumptions that describes past work - (a) omittance of an individual's strive for achieving cognitive coherence, (b) limited integration of important contextual factors - by utilizing networks of beliefs and incorporating social rank into the dynamics. As a result, we illustrate that: (i) an organization may appear to be increasingly coherent in terms of organizational culture, yet be composed of individuals with reduced levels of coherence, (ii) the components of social conformity - peer-pressure and social rank - are influential at different aggregation levels.Comment: 20 pages, 8 figure

    Grid-enabled Workflows for Industrial Product Design

    No full text
    This paper presents a generic approach for developing and using Grid-based workflow technology for enabling cross-organizational engineering applications. Using industrial product design examples from the automotive and aerospace industries we highlight the main requirements and challenges addressed by our approach and describe how it can be used for enabling interoperability between heterogeneous workflow engines

    Coordination approaches and systems - part I : a strategic perspective

    Get PDF
    This is the first part of a two-part paper presenting a fundamental review and summary of research of design coordination and cooperation technologies. The theme of this review is aimed at the research conducted within the decision management aspect of design coordination. The focus is therefore on the strategies involved in making decisions and how these strategies are used to satisfy design requirements. The paper reviews research within collaborative and coordinated design, project and workflow management, and, task and organization models. The research reviewed has attempted to identify fundamental coordination mechanisms from different domains, however it is concluded that domain independent mechanisms need to be augmented with domain specific mechanisms to facilitate coordination. Part II is a review of design coordination from an operational perspective

    Decision Support Tools for Cloud Migration in the Enterprise

    Full text link
    This paper describes two tools that aim to support decision making during the migration of IT systems to the cloud. The first is a modeling tool that produces cost estimates of using public IaaS clouds. The tool enables IT architects to model their applications, data and infrastructure requirements in addition to their computational resource usage patterns. The tool can be used to compare the cost of different cloud providers, deployment options and usage scenarios. The second tool is a spreadsheet that outlines the benefits and risks of using IaaS clouds from an enterprise perspective; this tool provides a starting point for risk assessment. Two case studies were used to evaluate the tools. The tools were useful as they informed decision makers about the costs, benefits and risks of using the cloud.Comment: To appear in IEEE CLOUD 201

    The New Crafts: On the Technization of the Workforce and the Occupationalization of Firms

    [Excerpt] In the late 1960s and early 1970s American students were told that the value of a college education was declining (see Freeman 1976). Although liberal arts students were particularly discouraged by reports of recent graduates driving taxicabs, even the demand for engineers and other technical specialists seemed bleak. Two decades later, the headlines have reversed. Study after study proclaims that American children are performing more poorly on achievement tests than the children of most other industrialized nations. Employers complain of a shortage of skilled workers: young people are said to be ill-prepared for the demands of the workplace and older workers are said to lack the educational background requisite for retraining (Johnson and Packer 1987). Studies by labor economists have largely confirmed the employers\u27 contentions and foretell of even greater shortages of skilled labor in the near future (Bishop and Carter 1991)
