The NASA teleconferencing system: An evaluation

The communication requirements of the Apollo project led to the development of a teleconferencing network which linked together, in an audio-fax mode, the several NASA centers and supporting contractors of the Apollo project. The usefulness of this communication linkage for the Apollo project suggested that the system might be extended to include all NASA centers, enabling them to conduct their in-house business more efficiently than by traveling to other centers. A pilot project was run in which seventeen NASA center and subcenters, some with multiple facilities, were connected into the NASA teleconferencing network. During that year, costs were charted and, at the end of the year, an evaluation was made to determine how the system had been used and with what results. The year-end evaluation of the use of NASA teleconferencing system is summarized

Design of a video teleconference facility for a synchronous satellite communications link

The system requirements, design tradeoffs, and final design of a video teleconference facility are discussed, including proper lighting, graphics transmission, and picture aesthetics. Methods currently accepted in the television broadcast industry are used in the design. The unique problems associated with using an audio channel with a synchronous satellite communications link are discussed, and a final audio system design is presented

The impact of ICT sophistication on geographically distant networks: the case of space physics as seen from France

This paper examines scientific collaboration between French public research teams and distant partners. We first analyse the role and the development of trust and then, the relation between the degree of sophistication of Information and Communication Technologies (ICT) and the constraint of geographical proximity. In that purpose, we present a typology of the different kinds of knowledge and a classification of technologies. A case study in the field of space physics allows us to confront our theoretical elements to real life. We study the evolution of ICT sophistication parallel to collaboration patterns. Finally, we give some recommendations for public funding of virtual networks.collaboratory, knowledge transfer, trust, ICT classification, space physics

Communications technology satellite: United States experiments and disaster communications applications

Ground antennas from 0.6 to 5.0 meters in diameter were used as remote earth terminals by the United States for both wideband (television) and narrowband (voice, data) communication in conjunction with the Canadian Hermes satellite's high power transmitter. Experiments summarized cover teleconferencing and duplex videoconferencing for medical, educational, and civic purposes, as well as the remote interpretation of multilingual broadcasts from the United Nations. The capabilities of the system during real and simulated disasters at airports are assessed. Particular attention is given to miniexperiments for flood control in the Mississippi River basin and in Johnstown, Pennsylvania during the 1977 flood

The implications of a change in business travel policy on the wider organisation and public policy

Business travel, although only accounting in the UK in 2008 for 3% of trips and 9% of the UK's domestic distance travelled (Department for Transport, 2009, pp28), form a higher proportion in major cities (15% of mileage in London), where transport networks are most congested. Additionally, business journeys can be time consuming and tiring for the business traveller, affecting work/life balance and productivity, and also costly for businesses and the economy. The carbon emissions from business travel are an important factor due to longer distances travelled and the high proportion of journeys undertaken by air. In some cases business travel can be as much as two thirds of an organisations total carbon emissions. This paper reports the findings of a study designed to understand the motivations and attitudes of key actors in private sector organisations towards business travel. These motivations include: • The increasing importance of business travel on business costs and productivity due to the recession • Reductions in carbon emissions and the links to corporate responsibility • The demands of customers to reduce carbon emissions through the procurement process • The extent to which advancements in virtual communication technologies reduce the need to travel • A greater awareness of the vulnerability of travellers and to business continuity highlighted by the volcanic ash cloud. The insights into these causal factors and an understanding of the business practices that support, and barriers that hinder a reduction in business travel, are important in forecasting and developing public policy to produce a more holistic approach to managing personal travel, for both business travel and the commute. This paper will report some of these insights and discuss how a change in business travel policy can have extensive repercussions within an organisation, resulting in major impacts on business travel behaviour
