Explores security issues that schools should consider before deciding to reduce campus lighting in order to control energy costs. Highlights factors to consider before creating a lighting reduction action plan. (GR)

Oscillating reactions have been extensively used in chemical demonstrations. They involve several chemical concepts about kinetics, catalysts, and thermodynamics. The spontaneous cyclic color change of a solution is an attraction in any educational-level course. Chemiluminescent reactions are also among the most fascinating demonstrations and have…

The perception of 2nd-order, texture-contrast-defined motion was studied for apparent-motion stimuli composed of a pair of spatially displaced, simultaneously visible checkerboards. It was found that background-relative, counter-changing contrast provided the informational basis for the perception of 2nd-order apparent motion; motion began where…

Education administrators make buying decisions for furniture based on many factors. Cost, durability, functionality, safety and aesthetics represent just a few. Those issues always will be important, but gaining greater recognition in recent years has been the role furniture plays in creating positive, high-performance learning environments. The…

The specific gray shades in a visual scene can be derived from relative luminance values only when an anchoring rule is followed. The double-anchoring theory I propose in this article, as a development of the anchoring theory of Gilchrist et al. (1999), assumes that any given region (a) belongs to one or more frameworks, created by Gestalt…

This paper reports on a literature review conducted in the UK for the Design Council and CfBT (Higgins et al., 2005) which looked at the evidence of the impact of environments on learning in schools. We have reviewed the available evidence regarding different facets of the physical environment and provided an analysis based on different areas of…

University and college campuses are not immune to acts of violence. Unfortunately there is limited information regarding violence in the academic setting among women employees. As such, the purpose of this exploratory research was to examine issues that female faculty and staff members have about safety on and around campus, including concerns…

This paper investigates learner response to a novel kind of intonation feedback generated from speech analysis. Instead of displays of pitch curves, our feedback is flashing lights that show how much pitch variation the speaker has produced. The variable used to generate the feedback is the standard deviation of fundamental frequency as measured…

The quality of indoor lighting can influence task performance, social interaction and communication, health and safety, visual comfort, student behavior, and aesthetic judgments. These by-products of lighting are examined in this literature review in an effort to define the conditions that are associated with good lighting quality. Lighting…

This instructional unit is one of 10 developed by students on various energy-related areas that deals specifically with lighting utilization. Its objective is for the student to be able to outline the development of lighting use and conservation and identify major types and operating characteristics of lamps used in electric lighting. Some topics…

Existing technologies that may have to be accommodated in libraries of the future include: microform catalogs, on-line catalogs, automated circulation systems, automated acquisition systems, video equipment, on-line reference services, facsimile transmission devices, microform reader-printers, and on-line cataloging terminals. Most of these…

Youth violence is a significant public health problem. Although the relationship between neighborhood-level factors and urban youth violence is recognized, the specific mechanisms of this relationship are often unclear. Prominent neighborhood individuals were identified within four select low-income urban neighborhoods in Baltimore City. In-depth…

A growing number of studies show that a school's physical condition--especially its lighting and indoor air quality--directly affect student performance. A 2005 Turner Construction survey of green buildings found that 70 percent of districts with sustainable schools reported improved student performance. It also makes perfect sense that…

The objective of this study is to offer a view on the different environmental factors that affect health (sound, light, colour, temperature) in the design, planning and organization of school premises. To achieve this, the authors first outline the problems leading to unhealthy situations. They subsequently analyse all the building and planning…
