Managing Public School Libraries in a Changing Environment
This paper presents some key management issues concerning public school libraries in the country. Also, discusses standards such as the IFLA/UNESCO School Library Manifesto on the Role of the School Library in Teaching and Learning for All as well as the Philippine School Library Standards including issues that deal with innovation and the new information landscape.
Elementary School Library Collections: A Content Analysis of Science Trade Books
In this study, science trade books from the libraries of 10 elementary schools across the United States were evaluated using the modified Hunsader rubric for their overall quality pertaining to science content, literacy, and critical literacy criteria. Findings indicate that 62% of the books met the overall science content criterion, 99% met the overall literacy criterion, and 41% met the overall critical literacy criterion. The majority of science trade books in each school were life science books, and the majority of books across all schools were 18–23 years old, with many being much older. Implications and recommendations are provided.
Geomagnetic micropulsations due to the motion of ocean waves
When sea waves move in the magnetic field of the earth, electric currents are generated in the water volume. These currents give rise to a small magnetic field which perturbs the earth's field. For plane trochoidal waves, this perturbing field decays exponentially with altitude and lies in a vertical plane which is oriented in the direction of wave propagation. The magnitude of the perturbing field also depends upon the magnitude and dip angle of the earth's field, and upon the height, wavelength, and propagation direction of the sea waves. For north-south waves, sea state 5, and an altitude of 100 feet, the perturbation is of the order of 0.1 gamma.
