INTERNATIONAL TELECOMMUNICATIONS: DYNAMICS OF REGULATION OF A RAPIDLY EXPANDING SERVICE AsImR H. ENDE* I A PROFILE OF THE REGULATORY ISSION The Communications Act of 1934, as amended' (the Communications Act), and the Communicatons Satellite Act of 19622 (the Satellite Act) provide for pervasive and all-encompassing federal regulation of international telecommunications. The basic purposes to be achieved by such regulation are declared to be "to make avail- able, so far as possible, to all the people of the United States a rapid, efficient, Nation-wide, and world-wide wire and radio communications service with adequate facilities at reasonable charges, ...." This broad and general statement of purposes is supplemented by the Declaration of Policy and Purposes in the Satellite Act. In that act, Congress declared it to be the policy of the United States to establish,-in conjunction and cooperation with other countries and as expeditiously as practicable, a commercial communications satellite system which, as part of an improved global communications network, would be responsive to public needs and national objectives, would serve the communications needs of this country and other countries, and would contribute to world peace and understanding In effectuating the above program, care and attention are to be directed toward providing services to economically less developed countries and areas as well as more highly developed ones, toward efficient and economical use of the frequency spectrum, and toward reflecting the benefits of the new technology in both the quality of the services provided and the charges for such services.4 United States participation in the global system is to be in the form of a private corporation subject to appropriate governmental regulation.5 All authorized users are to have nondiscriminatory access to the satellite system. -

The Future of Human-Computer Interaction: Overview of Input Devices
The future of human-computer interaction: overview of input devices Fabrizio Fornari School of Computer Science H´ask´olinn´ıReykjav´ık- Reykjav´ıkUniversity Reykjav´ık,Iceland November, 2012 Abstract We are in 2012 and we are still using the mouse and the keyboard to interact with a computer. We have seen a lot of changes in the world of Computer Science, relating to: performance, design and the way we interact with the computer. Differ- ent input devices have been developed around the computer, starting from the most recent touchscreens, continuing with webcams, microphones, and arriving to the oldest mice and keyboards. The aim of this research is to let the reader imagine a new way to interact with the computer. To reach our purpose, we introduce advanced technologies such as: Speech and Voice Recognition, Electronic Perception, Eye Tracking and Brain Computer In- terfaces. We propose examples of the cited technologies that may change the paradigm that saw, until now, keyboard and mouse as leaders of the input devices. 1 1 Introduction From the computer's birth1, we saw a lot of changes in the world of Com- puter Science. Changes relating to: performance, design and human-computer interaction [49]. A few years ago, the words \input device" evoked in our mind only two specific objects: the keyboard and the mouse - the main instruments used to provide data to a personal computer. Keyboard and mouse are, in fact, two of the first input devices in the history of computer. Nowadays, with the evolution of computers, we have a large set of input de- vices that changed the way we interact with the computer. -
Teaching with Technology: a Proposal for Using Amateur Radio in the Classroom
DOCUMENT RESUME ED 378 943 IR 016 946 AUTHOR Newell, Peter R. TITLE Teaching with Technology: A Proposal for Using Amateur Radio in the Classroom. PUB DATE Dec 94 NOTE 29p.; Adapted from a paper submitted in partial fulfillment of class requirements for VTE 500, Contemporary Concepts in Vocational-Technical Education, Spring 1994, and published in the 1994 American Radio Relay League National Educational Workshop proceedings. A"AILLE FROMPeter R. Newell, 8226 Trevi Lane, Clay, NY 13041 ($10).

DESCRIPTORS *Communication (Thought Transfer); Educational Innovation; *Educational Radio; Educational' Technology; Elementary Secondary Education; Interdisciplinary Approach; Language Arts; Self Esteem; *Student Motivation; ''Teaching Methods; *Vocational Education IDENTIFIERS *Ham Radio ABSTRACT Amateur radio is a technology and activity that offers great potential when integrated into academic or vocational curricula. Programs with electrical, electronics, and electromechanical content can benefit from the use of amateur radio, and can also enhance language and communications skills. The biggest value of amateur radio may lie in its ability to enhance a student's motivation and self-esteem. In addition to its specific vocational and technical applications, amateur radio can assist in teaching basic skills and in reducing the isolation of students and teachers as it promotes interdisciplinary education and cultural awareness. Amateur radio is distinctly different from citizens band, as it is a noncommercial service. Ham operators do not need an electronics background, although technical knowledge and skills are helpful. Several examples of the educational use of amateur radio illustrate its potential for academic and vocational education. -
A Simultaneous Radiotelephone and Visual Range Beacon for the Airways
RP341 A SIMULTANEOUS RADIOTELEPHONE AND VISUAL RANGE BEACON FOR THE AIRWAYS By F. G. Kear and G. H. Wintermute ABSTRACT Increased use of the airway radio services by transport operators has resulted in a demand for continuous range-beacon service. At the same time the weather broadcast information has increased in importance and the interruptions to the beacon service have become more frequent. To eliminate difficulties arising from this conflict a transmitting system has been developed which provides simul- taneous transmission of visual range-beacon and radiotelephone signals. This system is designed to employ existing equipment so far as possible. By combining two transmitting sets into one the cost of buildings and antenna equipment is reduced. Continuous check on the operation of both systems can be obtained with less personnel than required at present. The transmitting set consists of a 2-kw. radiotelephone transmitter operating into a nondirective antenna system and an additional set of amplifier branches supplying power through a goniometer into two loop antennas. The two antenna systems are symmetrically disposed with respect to each other, and coupling effects are balanced out to prevent distortion of the space pattern. The phase of the currents in the different antenna systems is controlled by a phase shift unit and means for checking the adjustment of this phase relationship continuously is provided. The equipment on the airplane to receive this service is changed only by the addition of a small filter unit which keeps the low-frequency reed voltages from reaching the head telephones and the voice frequencies from the reed indicator. -

Article a Look at S&T Awareness
SISSA – International School for Advanced Studies Journal of Science Communication ISSN 1824 – 2049 http://jcom.sissa.it/ Article A look at S&T Awareness - Enhancements in India Chandra Mohan Nautiyal Basing mainly on author's direct involvement in some science communication efforts in India, and other reports, this contribution depicts and analyses the present science communication/ popularization scenario in India. It tries to dispel a myth that rural people don't require or don’t crave for S&T information. It discusses need for science and technology communication, sustaining curiosity and creating role models. Citing cases of some natural, 'unnatural' and organized events, it recounts how S&T popularization efforts have fared during the past decade and a half. It's made possible using print, AV and interactive media which, at times, require lot of financial inputs. However, this contribution shows that a number of natural and other phenomena can be used to convince people about power of S&T and in molding their attitude. The cases cited may be from India, but, with a little variation, are true for most of the developing and under- developed societies. 1. Introduction Considering that nearly half of the Indian population is engaged in agriculture but contributes only about one fifth to the GDP, indicates a malaise and calls for more scientific and methodical approach in the farming sector. A change is needed not only in the information base but also the attitude. Therefore, there is a need to examine the role of Science and Technology (S&T) in their lives and ways to improve the level. -
