Purpose: The purpose of this study was to examine the influence of the heating, ventilation, and air-conditioning method on voice function following a voicing task using ecologically valid offices, one with radiant HVAC and one with forced air. Method: A total of 12 consented participants (6 women, 6 men) narrated a video in each of 4…

"Thermal comfort" (TC) -- how comfortable or satisfied a person is with the temperature of her/his surroundings -- is one of the key factors influencing the "indoor environmental quality" of schools, libraries, and offices. We conducted an experiment to explore how TC can impact students' learning. University students (n = 25)…

The integration of environmental policies with political support for action on these policies is of prime significance for mobilization and progression of improving indoor environments. However, state licensing agencies and local county ordinances for child care centers do not universally follow these policies and standards. As a result, most…

A 44-item questionnaire was designed to determine students' views about how useful various "specific" actions might be in helping to reduce global warming, their willingness to undertake these various actions and the extent to which these two might be related. The instrument was administered to students in Grades 6 to 12 (N = 1532) from…

Explore how melting ice sheets affect global sea levels. Sea-level rise (SLR) is a rise in the water level of the Earth's oceans. There are two major kinds of ice in the polar regions: sea ice and land ice. Land ice contributes to SLR and sea ice does not. This article explores the characteristics of sea ice and land ice and provides some hands-on…

Educating and communicating about climate change is challenging. Researchers reported that climate change concepts are often misunderstood. Some people do not believe that climate change will have impacts on their own life. Other challenges may include people's difficulty in perceiving small or gradual environmental changes, the fact that…

There is no doubt that in order to address the serious challenges arising from anthropogenic--or human-produced--climate change, Britain, along with the rest of the world, needs to adopt policies and develop skills that will create a low-carbon economy with a highly effective use of renewable and natural resources. People need to create the…

Understanding the importance of good indoor air quality (IAQ) in schools is the backbone of developing an effective Indoor Air Quality (IAQ) program. Poor IAQ can lead to a large variety of health problems and potentially affect comfort, concentration, and staff/student performance. In recognition of tight school budgets, this guidance is designed…

Educators and administrators are looking for new ways to boost student performance and eliminate barriers to learning. When working to improve the classroom environment, facility managers typically target the physical structure, temperature controls, humidity levels and ventilation. Many heating, ventilating and air conditioning (HVAC) consultants…

Reviews experimental data on various aspects of climate control. Includes a discussion of (1) the physics of cloud seeding, (2) the applications of cloud seeding, and (3) the role of statistics in the field of weather modification. Bibliography. (LC)

Offers suggestions and outlines procedures for the preservation of the resources of a small library. Brief sections discuss environment (temperature, humidity, housekeeping, light); library binding; simple in-house repairs; other protective measures (enclosures, microfilming); the care of unique objects; and disaster planning. A 21-item…

Reviews environmental studies which show that national climatic fluctuations vary over a wide range. Solar radiation, earth temperatures, precipitation, atmospheric gases and suspended particulates are discussed in relation to urban and extraurban effects. Local weather modifications and attempts at climate control by man seem to have substantial…

Presents concept of preventive conservation of archival records as a new science resulting from the use of modern techniques and chemicals. Various techniques for storage, proper environment, preventive de-acidification, fire prevention, restoration, and staff considerations are described. References are provided. (EJS)

Widespread use of solar energy is unsuccessful with large scale integration required and conservatism of responsible institutions. Rising fuel costs and government promotion may initiate expansion in commercial, environmental, and government establishments, homes, and schools. Difficulties encountered include financing, tax incentives, design,…
