Abstract:
Electroscopes are sensitive instruments useful for investigations of static electricity. They are devices that are used for detecting whether an object is charged or uncharged. They also determine the type of charge. Their operation is based on the principle of like sign charge repulsion.

Abstract:
Using music technology is a daily reality for music educators. The task may be as simple as readying a CD player for use in an elementary classroom or as complex as setting up a complete sound system--including microphones, mixer, amplifier, and speakers--for a live music production. One piece of music technology music educators constantly encounter is the audio mixer, usually referred to as "mixer." Mixers, found everywhere sound is recorded or reproduced, are vital to the sound recording and reproduction process. Yet few teachers are prepared for making more than rudimentary sense of the mixer's multiple knobs, buttons, and sliders. In this column, a framework is provided for understanding how music educators can better understand mixers by describing a mixer's essential sections: the input, channel strip, buss, and output sections. This article also offers tips to better enable educators to use mixers. (Contains 1 figure.) Note:The following two links are not-applicable for text-based browsers or screen-reading software.

Abstract:
Where as video cameras are a reliable and established technology for the measurement of kinematic parameters, accelerometers are increasingly being employed for this type of measurement due to their ease of use, performance, and comparatively low cost. However, the majority of accelerometer-based studies involve a single channel due to the difficulty associated with synchronizing multiple accelerometer channels. The authors of this article outline a method to synchronize multiple accelerometers using a maxima detection method. Results are presented that demonstrate the effectiveness of the new synchronization method with 52 of 54 recorded data sets showing no time lag error and two tests showing an error of 0.04 sec. Inter-instrument and instrument-video correlations are all greater than r = 0.94 (p less than 0.01), with inter-instrument precision (Root Mean Square Error; RMSE) approximately equal to 0.1ms[superscript -2], demonstrating the efficacy of the technique. In conclusion, the new technique offers a robust solution, giving further support to the movement toward wider adoption of accelerometer-based performance measurement systems in sports science.

Abstract:
Two of the most time-consuming jobs in the library are taking inventory and keeping track of in-house uses of library material. Librarians have long been searching for more efficient solution for these two activities. New technology can be the answer to creating efficiency for libraries. In fact, if one is a SirsiDynix library, there is an easy solution--the PocketCirc, a handheld device run through a PDA. Canadian University College (CUC), a small private university in Alberta, Canada, has a small staff and has to be proactive in finding ways to streamline library projects. As a technical services/systems librarian at CUC, part of this author's job is to provide information on emerging technologies that will help them meet this goal. In this article, Bailey shares her CUC library experience using the PocketCirc, which provides "easy online or offline access to key circulation and inventory functions...." (Contains 7 figures.)

Abstract:
Fitness programs can be greatly enhanced with the addition of fitness balls. They are a fun, challenging, economical, and safe way to incorporate a cardiovascular, strength, and stretching program for all fitness levels in a physical education setting. The use of these balls has become more popular during the last decade, and their benefits and uses have also become more common. This article described four kinds of fitness balls, and offered example exercises that can easily be implemented in the classroom. Although each ball is different in size and composition, they provide fresh opportunities for fitness in the classroom and help prepare students for a long and healthy lifetime. (Contains 22 photos.)

Abstract:
The history, scope, and evolving definitions of assistive technology reutilization activities, from both grassroots and legislative perspective, are discussed. A national classification system of AT reuse activities and data gathered from several national surveys of AT reutilization programs using this classification approach are presented. The rationale, benefits, and potential perils of AT reuse are discussed from the viewpoint of suppliers, consumers, agencies, and organizations engaged in AT reutilization activities. Examples of both successful and damaging AT reutilization initiatives are cited with cautionary recommendations to organizations interested in establishing or expanding AT reutilization initiatives. The role of the National Assistive Technology Reutilization and Coordination Technical Assistance Center (Pass It On Center) is shared. The value and limitations of the current AT reuse data and outcomes are discussed and recommendations for future research on AT reutilization activities and outcomes are offered.

Abstract:
Though the term, "probeware" may not be a household word, it has grown more familiar to science educators over the past decade, as a new generation of high-tech instruments for collecting and analyzing data from the physical world have been introduced into school science labs. Today, those tools include digital scientific probes or sensors that collect data on temperature, motion, gas pressure, light, and other characteristics. Other devices called "data loggers"-- either hand-held computers or interface boxes attached to computers--compile the data from probes, display them in real time, and transfer them to software that can analyze and present the information in various ways. Collectively, this gear, and the computer software with which it is integrated, is called "probeware." In 2007, the Concord Consortium completed the second of two three-year studies, financed by the National Science Foundation, on the use of probeware in school science instruction. The two studies, which used random assignment of teachers, were conducted in grades 3-8 in a variety of disciplines, including physical science, life science, technology, and engineering. The studies tested all available brands of school probeware, without distinguishing among manufacturers. They used the equipment with both hand-held and desktop computers, though with a common software interface developed by the consortium. In the first study, conducted from 2001 to 2004, students who used probeware scored significantly higher on pre- and post-tests in science compared with students who did not use probeware. The second study, from 2004 to 2007, met a higher research standard, "as close to the medical model as possible, with validated results," and also showed that students learned more using probeware.

Abstract:
Context: To ensure equitable access to prehospital care, as recommended by the Rural and Frontier Emergency Medical Services (EMS) Agenda for the Future, policymakers will need a uniform measure of EMS infrastructure. Purpose and Methods: This paper proposes a county-level indicator of EMS resource availability that takes into consideration existing EMS resources (ambulances), population health and demographics, and geographic factors. The indicator, the Expected annual emergency miles per AMBulance (EXAMB), provides a basis for comparing ambulance availability across counties within states. A method for calculating the EXAMB indicator is demonstrated using data from 5 states. Findings: The EXAMB indicator was negatively correlated with ambulance availability per 100,000 population in 4 of the 5 states in the study. The indicator was positively correlated with rurality in 3 states. In Mississippi, South Carolina, and Wyoming, whole-county health professional shortage areas had median EXAMB values 45%-81% higher than those of the non-health professional shortage areas counties. Conclusions: Future research should explore the relationship of the EXAMB to EMS outcomes, with the ultimate goal of developing a nationally recognized indicator of "adequate" EMS resource availability.
