Background: A nationwide survey of family members of people with intellectual and developmental disabilities ranging in age from birth through adulthood was conducted to replicate a similar effort by Wehmeyer and update the knowledge base concerning technology use by people with intellectual and developmental disabilities. Method: Survey responses provided information about use of technology for mobility, hearing and vision, communication, independent living, and in the area of computer use. In addition, survey items queried the use of electronic and information technology devices such as use of email, mobile telephones and digital cameras. Results: Survey results showed that although the use of computers for individuals with intellectual and developmental disabilities is more prevalent, other technology use frequency is much the same as in the late 1990s. However, technology needs did vary among school-age individuals over time. Conclusion: Implications of results for technology use of people with disabilities are discussed through the lens of frequency of use and needs for individuals with disabilities.

The magnetic properties of single crystal gadolinium-rich [Gd.sub.100-x][Y.sub.x] alloys are investigated using ac susceptibility, magnetization, and ultrasonic techniques, to determine the magnetic phase behavior in the region x [is less than] 10. For [Gd.sub.92.5][Y.sub.7.5], observations are consistent with a canting of the magnetic moment away from the c-axis toward the basal plane at 243 K, and a return toward the c-axis at lower temperatures. The precedence of a phase change at 116 K is confirmed. Index Terms--Ferromagnetic materials, gadolinium alloys, magnetic susceptibility, rare earth alloys.

The elastic constants and electrical transport properties of single-crystal Gd and Gd-Y are measured for Y⩽26 at. %. There are clear features in the elastic constant C[SUB33](T) and in the temperature) derivative of the a-axis resistivity, dρ[SUBa]/dT), at the accepted ferromagnetic Curie temperature (T[SUBC], and at the accepted spin-reorientation at T[SUBSR]. In the Gd-rich Gd-Y, there is a third feature at T[SUP*] below T[SUBSR], which is consistent with evidence for a further second-order transition. A modified magnetic phase diagram for Gd-Y is proposed. [ABSTRACT FROM AUTHOR]
