From flowers to palms: 40 years of policy for online learning

This year sees the 40th anniversary of the first policy paper regarding the use of computers in higher education in the United Kingdom. The publication of this paper represented the beginning of the field of learning technology research and practice in higher education. In the past 40 years, policy has at various points drawn from different communities and provided the roots for a diverse field of learning technology researchers and practitioners. This paper presents a review of learning technology-related policy over the past 40 years. The purpose of the review is to make sense of the current position in which the field finds itself, and to highlight lessons that can be learned from the implementation of previous policies. Conclusions drawn from the review of 40 years of learning technology policy suggest that there are few challenges that have not been faced before as well as a potential return to individual innovation

Integrated Online Media Management Systems For Media Centers: A Model For Selection And Effective Use

The researcher proposed to advice in the selection of an Integrated Online Library System (IOLS) for use in the 103 school media centers in the Palm Beach County Schools, Florida. This was accomplished by evaluating the two finalists of those vendors who answered the district\u27s Request for Proposal (RFP). Of the five vendors who responded to the RFP. CLSI and SIRSI were selected as the systems most likely to meet the needs of the media centers of the school district. An overview and definition of IOLS was first discussed. This overview then related itself to the needs of the school district as presented in the RFP. A selection criteria was then designed from previous research on the subject to help find the ideal system. The history and development of an Integrated Online Library System was important in seeing where the systems have originated in contrast to the systems in the Eighties to the also revealed the present time. Literature IOLS principles of operation. The Request for Proposal reflected the needs assessment discussed over several years of committee meetings of representatives from various schools. The committees explored IOLS automated options and compared these options. The RFP outlined the system requirements. Thoughts on staff attitudes while planning for a system were also considered. Each system was evaluated with the criteria outlined in the RFP. The background and capabilities of both systems were explored. This exploration took place where by the benchmark tests, on-site demonstrations systems were in use daily, conferences with the vendors, systems. And reading literature reviews on both systems. Evaluation guidelines and criteria were found in library resources. The functions required for terminal access requirements, process for data conversion, vendor background and reliability, contained in these library resources. And the cost were contained in these library resources. The results of this study culminated in the official recommendation of the SIRSI to be purchased by the district\u27s school board. It was the expectation of the author of this document to see the purchase of the recommended system by the school board and have it implemented in all the schools in the district within a three year period following the submission of the recommendation

The role of the host in a cooperating mainframe and workstation environment, volumes 1 and 2

In recent years, advancements made in computer systems have prompted a move from centralized computing based on timesharing a large mainframe computer to distributed computing based on a connected set of engineering workstations. A major factor in this advancement is the increased performance and lower cost of engineering workstations. The shift to distributed computing from centralized computing has led to challenges associated with the residency of application programs within the system. In a combined system of multiple engineering workstations attached to a mainframe host, the question arises as to how does a system designer assign applications between the larger mainframe host and the smaller, yet powerful, workstation. The concepts related to real time data processing are analyzed and systems are displayed which use a host mainframe and a number of engineering workstations interconnected by a local area network. In most cases, distributed systems can be classified as having a single function or multiple functions and as executing programs in real time or nonreal time. In a system of multiple computers, the degree of autonomy of the computers is important; a system with one master control computer generally differs in reliability, performance, and complexity from a system in which all computers share the control. This research is concerned with generating general criteria principles for software residency decisions (host or workstation) for a diverse yet coupled group of users (the clustered workstations) which may need the use of a shared resource (the mainframe) to perform their functions

Off-line computing for experimental high-energy physics

The needs of experimental high-energy physics for large-scale computing and data handling are explained in terms of the complexity of individual collisions and the need for high statistics to study quantum mechanical processes. The prevalence of university-dominated collaborations adds a requirement for high-performance wide-area networks. The data handling and computational needs of the different types of large experiment, now running or under construction, are evaluated. Software for experimental high-energy physics is reviewed briefly with particular attention to the success of packages written within the discipline. It is argued that workstations and graphics are important in ensuring that analysis codes are correct, and the worldwide networks which support the involvement of remote physicists are described. Computing and data handling are reviewed showing how workstations and RISC processors are rising in importance but have not supplanted traditional mainframe processing. Examples of computing systems constructed within high-energy physics are examined and evaluated

SLAWS: Towards a Conceptual Architecture for SLA Enforcement

Current technologies in Service Oriented Computing (SOC) provide a solid framework to drive the interaction of organizations from a functional point of view. in order to introduce non-functional properties in this scenario, the concept of Service Level Agreement (SLAs) comes into play as a key element. SLAs can be seen as containers of the functional and non-functional properties that both parties (the service consumer and the service provider) agree specifying its rights and obligations during the interaction. However this SLAs represent an additional responsibility for the service provider since it motivates the need of a SLAEnforcement process in its infrastructure. A proper SLAenforcement implies optimized resource usage that meet SLAs established with consumer, making it possible to the provider afford a larger number of customers to maximize its benefits. Current approaches to SLA enforcement are domainspecific approaches and/or based on monolithic platforms (from a SOC point of view).In this paper we propose a conceptual architecture (SLAWs) for SLA enforcement. The main goal of the proposed architecture is to be used as a conceptual framework to build a flexible SLA enforcement layer. This layer could be integrated in a seamless way in the pre-existing provider infrastructure when is based upon the service oriented architecture principles

Factors shaping the evolution of electronic documentation systems

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

Factors contributing to the use of computer-based information systems in student services

The purpose of this study was to determine what factors facilitate and what factors inhibit computer use in the Student Affairs Divisions of James Madison University (JMU), Virginia Polytechnic Institute (VPI), and Mary Washington College (MWC).;The population for this study was student affairs officials and related personnel deliberately selected from three Virginia public institutions.;The following conclusions were drawn from the findings of this study. (1) MWC is in the beginning stages of automation, JMU is moving in the direction of state-of-art technology while VPI\u27s current status has reached the level regarded as state-of-art. (2) The status of CBISs at MWC, JMU, and VPI is affected by the time period in which automation occurred. (3) Student affairs\u27 users at MWC, JMU, and VPI perceive CBISs positively. (4) Respondents believe using CBISs on the job simplifies tasks, helps monitor data flow, increases efficiency, makes output professional, makes data timely and accurate, improves the communication process, and does not significantly affect changes in policy. (5) No significant organizational changes have occurred at MWC or JMU while several organizational changes were identified at VPI. (6) The institution\u27s mission and size influence the direction institutions take in regard to computer technology. (7) Respondents were satisfied with the microcomputer support and training received. (8) All users mentioned mainframe computer support was slow and uneven and many outside influences seem to impact the quality of this service. (9) It is clear that at JMU and VPI the integrator\u27s role positively affects the use of computers. (10) The role, professional background, and personal characteristics of integrators were indentified and summarized. (11) Institutions of higher education should identify the integrators on their campuses and promote and support their role. (12) Top leadership commitment plays a crucial factor in facilitating computer use. (13) The lack of long range plans for the improved use of computers do not significantly affect the use of CBISs at MWC, JMU, or VPI.;Since very little research has been conducted on Student Affairs Divisions\u27 use of CBISs, future research should focus on how data collected on students improve the effective operation of student affairs offices
