An Investigation Of Factors Impacting The Use Of Technology In A Home School Environment
Home school populations have been studied for socialization and academic preparedness, but there are few studies on the use of technology among home schooled families. One researcher, in studying technology use among home school families in the greater Albany, New York area, found that the use of technology had a positive influence on the decision to home school and to allow home school families to create and maintain groups of like-minded home schoolers in their quest to educate their children. The objectives of this study are to understand what technologies are being used by home school families and about perception of technology in four areas of technology usage: 1) to build social networks, 2) acquire and share knowledge, 3) administrative actions and 4) instructional activities. This research shows that when technology is perceived as easier to use, it will lead to perceived usefulness, at a higher significance than leading to actual use. Further, it was surprising that the models did not show perceived usefulness leading to actual use, which is indicated in the literature

Building an Education Infrastructure for Allied Health
This article discusses the emerging Education Information Infrastructure. It uses a five
part framework (aggregating, organizing, using, tool building, and policy making) to
describe this infrastructure and then uses the same framework to argue for a tightly
coupled education information infrastructure specifically for allied health. This tightly
coupled education resource would allow educators, allied health professionals and the
general public to gain improved access to education resources on the Internet through
metadata and digital reference services. Specific benefits of the building effort are
discussed.Informatio
The Surface Wave Magnitude for the 9 October 2006 North Korean Nuclear Explosion
Surface waves were generated by the North Korean nuclear explosion of 9 October 2006 and were recorded at epicentral distances up to 34°, from which we estimated a surface wave magnitude (M_s) of 2.94 with an interstation standard deviation of 0.17 magnitude units. The International Data Center estimated a body-wave magnitude (m_b) of 4.1. This is the only explosion we have analyzed that was not easily screened as an explosion based on the differences between the M_s and m_b estimates. Additionally, this M_s predicts a yield, based on empirical M_s/yield relationships, that is almost an order of magnitude larger than the 0.5–1 kt reported for this explosion. We investigate how emplacement medium effects on surface wave moment and magnitude may have contributed to the yield discrepancy

A Study of the Technological, Instructional, and Motivational Factors Affecting Phr Certification Exam Outcomes
Although previous studies have considered the factors affecting other certification exam outcomes, they have not examined those that are related to performance on the Professional in Human Resources (PHR) exam. In response to that need, this study specifically investigates technology and training factors that affect self-efficacy and self-set goals, and through them, influence PHR certification exam results. The target population for the study consisted of recent examinees who had taken a formal PHR examination preparation class or used another form of exam preparation training. The survey results were analyzed using partial least squares modeling techniques, and mediation effects were then tested. The results demonstrated that PHR training self-efficacy affected PHR exam self-efficacy and self-set goals. These factors then had an impact on PHR exam scores. Also, the results of task-technology fit were indirectly related to PHR training self-efficacy through a multiple mediation model that included the instructional factor of time on task and the technology factor of perceived usefulness. Surprisingly, time spent on practice exam questions was found to be negatively related to PHR certification exam scores. Finally, instructional feedback indirectly affected outcomes through its positive relationship to self-set goals. The results of the research should help training professionals and examinees in structuring PHR exam training and preparation activities. They also suggest avenues for improving outcomes in other similar types of training
1.6 W continuous-wave Raman laser using low-loss synthetic diamond
Low-birefringence (Δn<2x10−6), low-loss (absorption coefficient <0.006cm−1 at 1064nm), single-crystal, synthetic diamond has been exploited in a CW Raman laser. The diamond Raman laser was intracavity pumped within a Nd:YVO4 laser. At the Raman laser wavelength of 1240nm, CW output powers of 1.6W and a slope efficiency with respect to the absorbed diode-laser pump power (at 808nm) of ~18% were measured. In quasi-CW operation, maximum on-time output powers of 2.8W (slope efficiency ~24%) were observed, resulting in an absorbed diode-laser pump power to the Raman laser output power conversion efficiency of 13%
