All laboratories, even modern high-tech ones, have some degree of hazard potential. It is the teacher's responsibility to make the lab as safe as possible and to do all that is reasonable and prudent to prevent accidents. The teacher's goal should be to insure the safety of every student. This goal is met best via well-planned instruction and…

In the absence of scientific clarity regarding the potential health effects of occupational exposure to nanoparticles, there is a need for guidance in making decisions about hazards, risks, and controls (Schulte & Salmanca-Buentello, 2007). Presently, no guiding principles have been universally accepted for personal protective equipment that is…

The understanding of complex physiological processes requires information from many different areas of knowledge. To meet this interdisciplinary scenario, the ability of integrating and articulating information is demanded. The difficulty of such approach arises because, more often than not, information is fragmented through under graduation…

We introduce a method for measuring effective government and modeling its consequences for social welfare at the individual level. Our focus is on the experiences of citizens living in African countries where famine remains a serious threat. If a government is effective, it will be able to deliver goods that individuals need to improve their…

The 2013 edition of the "Digest of Education Statistics" is the 49th in a series of publications initiated in 1962. The Digest has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field of American…

Sanitizers and disinfectants can play an important role in protecting public health. They are designed to kill "pests," including infectious germs and other microorganisms such as bacteria, viruses, and fungi. Unfortunately, sanitizers and disinfectants also contain chemicals that are "pesticides." Exposure to persistent toxic…

"MCPS School Safety and Security at a Glance" provides, in a single document, information about the reporting of incidents related to school safety and security, school climate, local school safety program descriptions, and serious incidents. Information is presented for each Montgomery County (Maryland) public school. While much of this…

Socio-scientific issues have become increasingly important in Science-Technology-Society (STS) education as a means to make science learning more relevant to students' lives. This study used the e-waste issue as a context to investigate two aspects of socio-scientific decision-making: (1) the relationship between the nature of science (NOS)…

This paper analyses the design parameters for an absorber used for removal of toxic acid gas (in particular sulfur dioxide) from a process gas stream for environmental health protection purposes. Starting from the equilibrium data, Henry's law constant was determined from the slope of the y-x diagram. Based on mass balances across the absorber,…

We evaluated the effectiveness of group safety training and in situ feedback and response interruption to teach preschool children to avoid consuming potentially hazardous substances. Three children ingested ambiguous substances during a baited baseline assessment condition and continued to ingest these substances following group safety training.…

We connected youth of the Mushkegowuk Territory (specifically Fort Albany First Nation) with environmental science and technology mentors in an outreach program contextualized to subarctic Ontario that addressed some of the environmental concerns identified by members of Fort Albany First Nation. Most activities were community-based centering on…

This dissertation has two areas of focus: learning and developmental disorders (LDDs) and polyfluoroalkyl chemicals (PFCs). Epidemiological and exposure assessment methods are applied to each. The first paper used geographic location as a surrogate for exposure and broadly assesses the effect of the environment, both physical and social, on LDD…

"Child Care Health Connections" is a bimonthly newsletter published by the California Childcare Health Program (CCHP), a community-based program of the University of California, San Francisco School of Nursing, Department of Family Health Care Nursing. The goals of the newsletter are to promote and support a healthy and safe environment…

To use Lisbeth Schorr's term, children who are at risk for "rotten outcomes" are not randomly scattered throughout the society but are, rather, concentrated in impoverished neighborhoods. In recent decades, government policy and public opinion in the U.S. has reflected the belief that children who experience rotten outcomes are, at least…

Purpose: To conduct an assessment of rural environmental pollution sources and associated population mortality rates. Methods: The design is a secondary analysis of county-level data from the Environmental Protection Agency (EPA), Department of Agriculture, National Land Cover Dataset, Energy Information Administration, Centers for Disease Control…
