    The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments

    Managing knowledge means managing the processes of creation, development, distribution and utilisation of knowledge in order to improve organisational performance and increase competitive capacity. However, serious difficulties arise when attempts are made to implement knowledge management in enterprises. One of the reasons behind this situation is the lack of suitable methodologies for guiding the process of development and implementation of a Knowledge Management System, which is a computer system that allows the processes of creating, collecting, organising, accessing and using knowledge to be automated as far as possible. In this paper we propose a methodology for directing the process of developing and implementing a Knowledge Management System in any type of organisation. The methodology is organised in phases and outlines the activities to be performed, the techniques and supporting tools to be used, and the expected results for each phase. In addition, we show how the proposed methodology can be applied to the particular case of an enterpris

    A machine-checked proof of security for AWS key management service

    We present a machine-checked proof of security for the domain management protocol of Amazon Web Services' KMS (Key Management Service) a critical security service used throughout AWS and by AWS customers. Domain management is at the core of AWS KMS; it governs the top-level keys that anchor the security of encryption services at AWS. We show that the protocol securely implements an ideal distributed encryption mechanism under standard cryptographic assumptions. The proof is machine-checked in the EasyCrypt proof assistant and is the largest EasyCrypt development to date.Manuel Barbosa was supported by grant SFRH/BSAB/143018/2018 awarded by the Portuguese Foundation for Science and Technology (FCT).

    Information Systems and Healthcare XXXIV: Clinical Knowledge Management Systems—Literature Review and Research Issues for Information Systems

    Get PDF
    Knowledge Management (KM) has emerged as a possible solution to many of the challenges facing U.S. and international healthcare systems. These challenges include concerns regarding the safety and quality of patient care, critical inefficiency, disparate technologies and information standards, rapidly rising costs and clinical information overload. In this paper, we focus on clinical knowledge management systems (CKMS) research. The objectives of the paper are to evaluate the current state of knowledge management systems diffusion in the clinical setting, assess the present status and focus of CKMS research efforts, and identify research gaps and opportunities for future work across the medical informatics and information systems disciplines. The study analyzes the literature along two dimensions: (1) the knowledge management processes of creation, capture, transfer, and application, and (2) the clinical processes of diagnosis, treatment, monitoring and prognosis. The study reveals that the vast majority of CKMS research has been conducted by the medical and health informatics communities. Information systems (IS) researchers have played a limited role in past CKMS research. Overall, the results indicate that there is considerable potential for IS researchers to contribute their expertise to the improvement of clinical process through technology-based KM approaches

    A Knowledge Management System (KMS) Using a Storytelling-based Approach to Collect Tacit Knowledge

    Get PDF
    Since the 1990s, Knowledge Management Systems (KMS) have been largely unsuccessful in the collection of tacit knowledge. The process, whether through direct input by the holder of the tacit knowledge or through an intermediary such as the collection of tacit knowledge through interviews and videos, has not succeeded. Reasons encompass the organizational (such as culture of the organization), the technological (example: poor tools), and the individual (example: knowledge is power, i.e. where experts with rare knowledge results in knowledge hoarding instead of transfer). The purpose of this study was to demonstrate that tacit knowledge could be successfully and consistently collected from the participants themselves and placed into a KMS using a storytelling-based approach. This study extended past research that collected stories for KMS’ using interviews and videos by having participants directly entering their data, as stories, into a KMS. This was a new approach and it was posited that having participants use stories to enter their tacit knowledge themselves into a KMS would overcome their reluctance to provide tacit knowledge thus overcoming barriers to providing tacit knowledge into a KMS The validation methodology was based upon three elements: the deep-dive research element, the issues and solution element, and the dissertation proposition element. The deep-dive research element was the extensive research for the study into knowledge management, storytelling, and other various methods for collection of tacit knowledge. The issues and solution element consisted of issues about tacit knowledge that were identified from the deep-dive research element, i.e. general arguments constructed about knowledge management which were backed by data from research into knowledge management systems and storytelling. Theoretical solutions to the issues regarding the capture of tacit knowledge were then constructed which included the storytelling-based approach and a KMS framework for the collection of tacit knowledge. Lastly was the dissertation proposition element which consisted of a thorough analysis of the survey data against each of the dissertation propositions. There were three propositions. Proposition 1 was sharing of knowledge and the storytelling-based approach. Proposition 2 was about the framework, the scenarios, guiding questions, and Communities of Practice (CoP), and Proposition 3 was about participant knowledge and interaction with forums. Each proposition was evaluated independently. The study was successful and validated propositions 1 and 2. For proposition 1, 81% of the participants responded positively to the eight study questions directed towards this proposition. For all eight questions across all 21 participants, the mean was 29.952 against a target test mean of 24 with a range of 27.538-32.367. For proposition 2, 76.19% of participants scored this section positive. For all six questions across all 21 participants, the mean was 23 against a target test mean of 18 with a range of 21.394-24.606. However, the results for proposition 3 were inconclusive and must be considered a failure. Most of the respondents either scored ‘no change’ to at least 50% of the questions or they stated they had never been to a forum. For all four questions across all 21 participants, the mean was 12.905 against a target mean of 12 with a range of 11.896-13.914. Based upon propositions 1 and 2, the null hypothesis was disproved. Participants liked the storytelling-based approach, providing their tacit knowledge, and they liked the framework

    This report summarizes academic research which has resulted in an increased appreciation for multidisciplinary efforts among our students, colleagues and administrators. It has also generated a number of research ideas that emerged from the interaction between disciplines. Overall, 17 undergraduate students and 16 graduate students benefited directly from the NASA grant: an additional 11 graduate students were impacted and participated without financial support from NASA. The work resulted in 16 theses (with 7 to be completed in the near future), 67 papers or reports mostly published in 8 journals and/or presented at various conferences (a total of 83 papers, presentations and reports published based on NASA inspired or supported work). In addition, the faculty and students presented related work at many meetings, and continuing work has been proposed to NSF, the Army, Industry and other state and federal institutions to continue efforts in the direction of multidisciplinary and recently multi-objective design and analysis. The specific problem addressed is component packing which was solved as a multi-objective problem using iterative genetic algorithms and decomposition. Further testing and refinement of the methodology developed is presently under investigation. Teaming issues research and classes resulted in the publication of a web site, (http://design.eng.clemson.edu/psych4991) which provides pointers and techniques to interested parties. Specific advantages of using iterative genetic algorithms, hurdles faced and resolved, and institutional difficulties associated with multi-discipline teaming are described in some detail

    Reforming and privatizing Hungary's road haulage

    Get PDF
    The Volan units (previously unitary but now formally dismembered) provide public transport services for both passengers and freight, and make up the largest enterprise in Hungary's road transport industry. Immediately after separation in 1989, the Volan group of units employed 67,000 persons and operated 12,672 trucks and 8,010 buses. In 1989 Volan carried 34 percent of Hungary's professional road haulage tonne-kilometers. This report focuses on options for restructuring the Volan group. It therefore also considers the content and implementation of Hungary's overall road transport policy as well as related questions of finance and taxation, all of which define the conditions under which the Volan successor enterprises, however transformed, will have to prove themselves.Roads&Highways,Banks&Banking Reform,Municipal Financial Management,Transport and Trade Logistics,Common Carriers Industry

    Managing Metadata in Data Warehouses: Pitfalls and Possibilities

    Get PDF
    This paper motivates a comprehensive academic study of metadata and the roles that metadata plays in organizational information systems. While the benefits of metadata and challenges in implementing metadata solutions are widely addressed in practitioner publications, explicit discussion of metadata in academic literature is rare. Metadata, when discussed, is perceived primarily as a technology solution. Integrated management of metadata and its business value are not well addressed. This paper discusses both the benefits offered by and the challenges associated with integrating metadata. It also describes solutions for addressing some of these challenges. The inherent complexity of an integrated metadata repository is demonstrated by reviewing the metadata functionality required in a data warehouse: a decision support environment where its importance is acknowledged. Comparing this required functionality with metadata management functionalities offered by data warehousing software products identifies crucial gaps. Based on these analyses, topics for further research on metadata are proposed
