Analysis of the TEL-PHONE Telecoil Simulator Program

Coudurier, Julie Ann 06 April 2004 (has links)
The TEL-PHONE Telecoil Simulator Program was invented as a solution to the problem of customizing programmable telecoils (T-coils) in a standardized and convenient manner. The objective of this project was to evaluate the suitability of the device for clinical use. A preliminary review of the TEL-PHONE protocol revealed that the protocol was in need of refinement. Following a preliminary examination of the TEL-PHONE device, a detailed evaluation of acoustic and electromagnetic output was conducted. The output was analyzed using information gleaned from Electronic Industries Association Recommended Standard RS-504 (EIA RS-504) Magnetic Field Intensity Criteria for Telephone Compatibility with Hearing Aids and American National Standards Institute (ANSI) S3.22-1996 Specification of Hearing Aid Characteristics. This analysis indicated that the controls on the device were not reliable and the output did not approximate that of a standard telephone.

The efficacy of visual telephony as a means of social support in socially isolated nuring home residents

Elkins, Tamera L. 01 January 1988 (has links) (PDF)
Nursing home residents often experience loneliness and social isolation. Research indicates that visitation via the telephone can decrease feelings of social isolation and loneliness. The purpose of this study was to introduce visual images to the telephone conversations of this population. It was hypothesized that the residents receiving this intervention would evidence decreased levels of loneliness and a greater sense of social support. This hypothesis was not supported by the data; however, emotional and social loneliness scores did show positive trends that may have been due to the intervention.

Att finna kärleken @ Internet : en studie om hur kommunikationen mellan åtta par utvecklats från det första mötet online till det första mötet offline

Johansson, Carolin January 2008 (has links)
<p>Purpose/aim: The purpose is to get increased knowledge about how the communication had developed from the first contact online to the first meeting in real life and even after when it had turned into a real relationship. I also wanted to know why the eight women I interviewed experienced that the Internet is a good venue to meet and develop a real relationship at and if there existed any differences between those four women who were a bit older and those four women who were young.</p><p>Material/method: When the purpose with this survey stood clear I decided to use interviews as the method to find out more about my subject. I decided to do eight interviews and I contacted eight women who all found their partners online that were willing to help me and answer my interview questions. I did six of the total eight interviews through MSN Messenger and the other two through the telephone.</p><p>Main results: I found out that three of the older women had used e-mail and telephone and sometimes SMS communication to find out more about their soon to be partner and after that decided to meet the other person in real life. One of the older women and all four of the younger ones had used a Community and Instant Messenger to communicate with their soon to be partner, they also used the telephone and SMS to communicate with each other but Instant Messenger was the medium that dominated in their wish to communicate. Those instant messenger communications were also a difference that I came to see between how the younger and older women communicated and the fact that three of the older women told me that they had used the Internet to search for a partner while one of the older women and all of the younger ones told me they didn’t search for anyone at all it just happened that they found someone and came to like that person.Keywords: Internet dating, instant messaging, Community, computer mediated communication, telephone communication, face to face communication.</p>
