    The application of telecommunications and telecomputing was investigated as a means of reducing NASA's consumption of natural resources and the proliferation of paper copies of correspondence. The feasibility, operational advantages, and limitations of decentralized (remote) neighborhood offices (NOC) linked through an electronic network are demonstrated. These offices are joined to a management information system for correspondence tracking, and to an administrative office center service based on the use of magnetic medium word processing typewriters which handle the daily typing load. In connection with an augmented teleconference network, a uniform means is provided for creating, storing, and retrieving administrative documents, records, and data, while simultaneously permitting users of the system to track their status. Information will be transferred without using paper - merely through digital electronic communication and display, as a step toward the establishment of an agency-wide electronic mail system

    Get PDF
    This report is an attempt to collect and synthesize current knowledge about computer-mediated communication systems. It focuses on computerized conferencing systems, for which most evaluational studies have been conducted, and also includes those electronic mail and office support systems for which evaluative information is available. It was made possible only through the participation of the many systems designers and evaluators listed below, who took the time to help to build a common conceptual framework and report their findings in terms of that common framework

    Performance awareness: execution performance of HEP codes on RISC platforms,issues and solutions

    The work described in this paper was started during the migration of Aleph's production jobs from the IBM mainframe/CRAY supercomputer to several RISC/Unix workstation platforms. The aim was to understand why Aleph did not obtain the performance on the RISC platforms that was "promised" after a CERN Unit comparison between these RISC platforms and the IBM mainframe. Remedies were also sought. Since the work with the Aleph jobs in turn led to the related task of understanding compilers and their options, the conditions under which the CERN benchmarks (and other benchmarks) were run, kernel routines and frequently used CERNLIB routines, the whole undertaking expanded to try to look at all the factors that influence the performance of High Energy Physics (HEP) jobs in general. Finally, key performance issues were reviewed against the programs of one of the LHC collaborations (Atlas) with the hope that the conclusions would be of long- term interest during the establishment of their simulation, reconstruction and analysis codes

    Feminist Information Activism: Newsletters, Index Cards and the 21st Century Archive

    Get PDF
    Feminist Information Activism: Newsletters, Index Cards and the 21st-century Archive develops an original approach to studying feminisms media infrastructures, focusing on U.S. lesbian feminism from the early 1970s to the present. The dissertation proposes the concept of feminist information activism, in which engagements with commonplace media facilitate access to marginalized information and networks through purposefully designed interfaces. Newsletter print culture and other activist-oriented information contexts such as bibliographic and indexing projects, and community archives, sought to unite feminist publics with difficult-to-find published materials. In each of these cases, activists worked to collect and parse large amounts of information that would make marginal lesbian lives visible, adopting various information management and compression techniques to do so. These tactics often created anxieties over the effects rationalization procedures might have on information that ultimately attempted to represent messy and politically complex feminist lives. To address these tensions, activists re-worked existing standards in information management through the use of new networks, the design of unique subject-classification schemes, and the appropriation of tools such as index cards and early computer databases. Chapter one investigates 1970s newsletter culture, drawing on a select print archive to argue that these documents imagined a mode of network thinking critical to feminist social movements prior to the web. Chapter two examines indexing and bibliography projects of the 1980s, tracing their critical appropriations of early database computing through interviews, archival research in these projects papers, and historical research on indexing standards gathered from late 20th-century instructional manuals. Chapters three and four draw out connections between these print forms and todays digital feminisms through a study of ongoing digitization practices at the Lesbian Herstory Archives. Through interviews and observation with archives staff, and documentary research in organizational records, these chapters examine feminisms influence on the design and implementation of accessible digitization projects that counter accepted archival standards. Framed by the historical chapters on feminist print activism; this study of feminist digitization re-casts indexing and bibliographic projects of the 1980s, and newsletters of the 1970s as media histories that situate todays digital feminisms in a longer genealogy.Feminist Information Activism: Newsletters, Index Cards and the 21st-century Archive develops an original approach to studying feminisms media infrastructures, focusing on U.S. lesbian feminism from the early 1970s to the present.

    A Charge Simulation Based Computer-Aided Design Implementation of High Voltage Systems Modelling

    Get PDF
    A Charge Simulation based Computer-Aided Design (CAD) Package which facilitates the development of a charge simulation model for high voltage (HV) systems consisting of a number of electrodes and one or two dielectric regions has been developed. The package calculates the potential and electric field distributions for practical systems. It avoids the necessity for creating individual programs for each system studied by allowing the geometry to be specified using a minimum of entered data. The application of the CAD package to several electrode systems which have analytical solutions is presented. Good agreement, generally within 0.5% was found between the fields produced by the Charge Simulation Method (CSM) and the analytical results. A study of the effect of several parameters controlling the charge simulation model is conducted to determine their optimum ranges. Recommendations for these values are made. It is found that for best simulation, discontinuities in alignment of the simulating charges should be avoided. The rod-plane gap configuration and a HV shielding system are modelled and results are compared with existing literature values. Some simulation quality measures which have not previously been published are given. The computation of fields in a sphere/slab arrangement is conducted and results are presented for a wide range of permittivity ratios and gap spacings. It is found that the maximum electric field strength occurs at the triple point for high dielectric constant unrecessed slabs, and away from the axis for low dielectric constant slabs. Two high. voltage systems which have not been analyzed before using the CSM are studied. One is a rotationally symmetrical triggering electrode configuration. The other is a 22 - shed - V - polymer insulator with a grading ring included to reduce the non-linearity of the voltage distribution. In the triggering electrode system it is found that both the main gap distance and the pilot gap distance affect the potential and the field distributions along the axial main gap line. The location of the maximum electric field changes with both gaps and always occurs on the hemispherical part of the triggering electrode, but not necessarily at the tip. Optimum values for the location and size of the grading ring are determined for the polymer insulator. TI1e simulations of additional complicated three-dimensional field problems with and without axial symmetry using the CSM are presented. A tilted rod-electrode versus ground plane and a hemispherical capped rod electrode versus a grounded plane with another offset hemispherically capped electrode embedded are modelled. A detailed examination of the field distribution for a triggering high voltage system without axial symmetry is also presented

    Wellness programs and administrative procedures: implications for teacher use of short term sick leave in Iowa schools

    This study was conducted to determine the selected factors which affected teacher use of short term sick leave in Iowa public school districts from 1980 through 1989. The selected factors were grouped into two categories, wellness programs and administrative procedures;The seven selected factors in the wellness category include exercise programs, incentives, medical screening, nutrition programs, lifestyle management programs, fitness assessment, and a wellness newsletter. The six selected factors in the administrative procedure category include teachers calling their supervisor when ill, attendance as part of evaluation, district policy on teacher attendance, attendance monitoring systems, incentives for positive attendance, and positive feedback on teacher attenDance;;As a related aspect of this study, several other factors were analyzed to determine any influence on teacher use of sick leave. These factors included the size of district, the health insurance carrier, and a rebate given to the school district by the health insurance carrier;Four hundred thirty-one questionnaires were distributed to superintendents and wellness coordinators in Iowa public schools. The questionnaires were intended to determine use of wellness activities, administrative procedures, and the number of short term teacher sick days used in each district. The short term sick days were calculated by subtracting from the total district teacher sick days all teacher sick days of 30 or more consecutive days accumulated for any teacher(s);Analyses of the data indicate that only those districts which offered lifestyle management programs affected the use of short term teacher sick leave. This study was unable to identify a significant relationship between any of the other factors and teacher use of short term sick leave
