    Adoption of an aggressive computer science research and technology program within NASA will: (1) enable new mission capabilities such as autonomous spacecraft, reliability and self-repair, and low-bandwidth intelligent Earth sensing; (2) lower manpower requirements, especially in the areas of Space Shuttle operations, by making fuller use of control center automation, technical support, and internal utilization of state-of-the-art computer techniques; (3) reduce project costs via improved software verification, software engineering, enhanced scientist/engineer productivity, and increased managerial effectiveness; and (4) significantly improve internal operations within NASA with electronic mail, managerial computer aids, an automated bureaucracy and uniform program operating plans

    Content analysis: What are they talking about?

    Quantitative content analysis is increasingly used to surpass surface level analyses in Computer-Supported Collaborative Learning (e.g., counting messages), but critical reflection on accepted practice has generally not been reported. A review of CSCL conference proceedings revealed a general vagueness in definitions of units of analysis. In general, arguments for choosing a unit were lacking and decisions made while developing the content analysis procedures were not made explicit. In this article, it will be illustrated that the currently accepted practices concerning the ‘unit of meaning’ are not generally applicable to quantitative content analysis of electronic communication. Such analysis is affected by ‘unit boundary overlap’ and contextual constraints having to do with the technology used. The analysis of e-mail communication required a different unit of analysis and segmentation procedure. This procedure proved to be reliable, and the subsequent coding of these units for quantitative analysis yielded satisfactory reliabilities. These findings have implications and recommendations for current content analysis practice in CSCL research

    Towards a better understanding of the e-health user: comparing USE IT and Requirements study for an Electronic Patient Record.

    This paper compares a traditional requirements study with 22 interviews for the design of an electronic patient record (EPR) and a USE IT analysis with 17 interviews trying to understand the end- user of an EPR. Developing, implementing and using information technology in organizations is a complex social activity. It is often characterized by ill-defined problems or vague goals, conflicts and disruptions that result from organizational change. Successfully implementing information systems in healthcare organizations appears to be a difficult task. Information Technology is regarded as an enabler of change in healthcare organizations but (information) technology adoption decisions in healthcare are complex, because of the uncertainty of benefits and the rate of change of technology. (Job) Relevance is recognized as an important determinant for IS success but still does not find its way into a systems design process

    Effective Virtual Teams for New Product Development

    At present, the existing literature shows that the factors which influence the effectiveness of virtual teams for new product development are still ambiguous. To address this problem, a research design was developed, which includes detailed literature review, preliminary model and field survey. From literature review, the factors which influence the effectiveness of virtual teams are identified and these factors are modified using a field survey. The relationship between knowledge workers (people), process and technology in virtual teams is explored in this study. The results of the study suggest that technology and process are tightly correlated and need to be considered early in virtual teams. The use of software as a service, web solution, report generator and tracking system should be incorporated for effectiveness virtual teams

    Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach

    Get PDF
    Unified Modelling Language (UML) is the most popular modelling language use for software design in software development industries with a class diagram being the most frequently use diagram. Despite the popularity of UML, it is being affected by inconsistency problems of its diagrams at the same or different abstraction levels. Inconsistency in UML is mostly caused by existence of various views on the same system and sometimes leads to potentially conflicting system specifications. In general, syntactic consistency can be automatically checked and therefore is supported by current UML Computer-aided Software Engineering (CASE) tools. Semantic consistency problems, unlike syntactic consistency problems, there exists no specific method for specifying semantic consistency rules and constraints. Therefore, this research has specified twenty-four abstraction rules of class‟s relation semantic among any three related classes of a refined class diagram to semantically equivalent relations of two of the classes using a logical approach. This research has also formalized three vertical semantic consistency rules of a class diagram refinement identified by previous researchers using a logical approach and a set of formalized abstraction rules. The results were successfully evaluated using hotel management system and passenger list system case studies and were found to be reliable and efficient

    The effect of functional roles on group efficiency

    Get PDF
    The usefulness of ‘roles’ as a pedagogical approach to support small group performance can be often read, however, their effect is rarely empirically assessed. Roles promote cohesion and responsibility and decrease so-called ‘process losses’ caused by coordination demands. In addition, roles can increase awareness of intra-group interaction. In this article, the effect of functional roles on group performance, efficiency and collaboration during computer-supported collaborative learning (CSCL) was investigated with questionnaires and quantitative content analysis of e-mail communication. A comparison of thirty-three questionnaire observations, distributed over ten groups in two research conditions: role (n = 5, N = 14) and non-role (n = 5, N = 19), revealed no main effect for performance (grade). A latent variable was interpreted as ‘perceived group efficiency’ (PGE). Multilevel modelling (MLM) yielded a positive marginal effect of PGE. Groups in the role condition appear to be more aware of their efficiency, compared to groups in the ‘non-role’ condition, regardless whether the group performs well or poor. Content analysis reveals that students in the role condition contribute more ‘task content’ focussed statements. This is, however, not as hypothesised due to the premise that roles decrease coordination and thus increase content focused statements; in fact, roles appear to stimulate coordination and simultaneously the amount of ‘task content’ focussed statements increases

    The Effect of Standardized Photodocumentation on Coding of Pressure Injuries

    Background and Purpose: Pressure injuries (PI) are prevalent and costly for hospitals. Hospitals implement different practices to accurately document PIs ranging from pen and paper to photodocumentation in electronic medical records (EMRs). In some instances, PIs that have been documented are not coded for billing and reporting. The purpose of this study is to determine if different documentation practices affect the number of coded PIs. Methods: Counts of coded PIs were collected from 2011- 2017 from two hospitals: a 500-bed acute care hospital (ACH) and a 42-bed acute rehabilitation hospital (ARH). A series of PI documentation practices were implemented over the course of the six years data were collected. The aim of the changes were to improve the accuracy of wound assessment, facilitate transparent and accurate reporting, and improve care. The four documentation practice time periods included 1) baseline, 2) PI photodocumentation with paper and all paper charting, 3) PI photodocumentation on paper and EMR for all other charting, and finally 4) all charting and documentation in the EMR. Results: In the 500-bed facility, a statistically significant difference was found in the mean number of PIs coded among the four documentation periods (F(3) = 45.460; p \u3c 0.001), with the highest number of PI’s reported during PI photodocumentation with paper and all paper charting. In the ARH there was a statistically significant difference in the average number of PIs among the four different documentation periods (Period 1-ARH Mean = 56, Period 2-ARH Mean = 31, SD = 11.3, Period 3-ARH Mean = 36.1, SD = 14.4, Period 4-ARH Mean = 58.7, SD = 11.3; F(3) = 5.994; p = 0.006). In post hoc analysis a significant difference between Period 2-ARH and Period 4-ARH (p = 0.036), as well as between Period 3-ARH and Period 4-ARH (p = 0.005) was observed. Discussion: Changes in documentation practice coincided with significant changes in the number of PIs being coded in the ACH and ARH. Improper or inaccurate documentation of PIs has the potential to result in inaccurate coding and therefore missed payment for services provided. More serious PIs that are not coded properly may cost the facility thousands of dollars in missed payments. Accurate assessment and subsequent coding of PIs ensures the facility is fairly compensated for services provided
