Interactive learning environments provide new opportunities for fine-grained tracking of student performance. These environments typically provide progressions of related problems, and allow students to make multiple attempts at solving each problem as well as access hints or other resources. We explore how students’ understanding of chemical reactions changes based on their interactions with C...

The increasing use of tissue dosimetry estimated using pharmacokinetic models in chemical risk assessments in various jurisdictions necessitates the development of internationally recognized good modelling practice (GMP). These practices would facilitate sharing of models and model evaluations and consistent applications in risk assessments. Clear descriptions of good practices for (1) model de...

Under the 1996 Amendments to the Safe Drinking Water Act (1), the U.S. Environmental Protection Agency (U.S. EPA) must consider susceptible subpopulations in its health risk assessments. The amendments mention specific groups, including young children, the elderly, pregnant women, and people who are immunocompromised by disease or treatment for diseases. The concept of susceptibility to adverse...

The Office of Ocean Resources Conservation and Assessment (ORCA) provides decisionmakers comprehensive, scientific information on characteristics of the oceans, coastal areas, and estuaries of the United States of America. The information ranges from strategic, national assessments of coastal and estuarine environmental quality to real-time information for navigation or hazardous materials spil...

Boron nitride quantum dots (BNQDs) have gained increasing attention for their versatile fluorescent, optoelectronic, chemical, and biochemical properties. During the past few years, significant progress has been demonstrated, started from theoretical modeling to actual application. Many interesting properties applications reported, such as excitation-dependent emission (and, in some cases, non-...

The etiology of a child's cognitive ability is complex, with research suggesting that it is not attributed to a single determinant or even a defined period of exposure. Rather, cognitive development is the product of cumulative interactions with the environment, both negative and positive, over the life course. The aim of this systematic scoping review was to collate evidence associated with ch...

Faced with the non-optional acceptance of toxic chemical artifacts, ubiquitous interweaving chemicals in our social fabric oft en exists out sight and mind. Yet, for many, exposures signal life-changing or life-ending events, phantom threats that fail to appear as such until they become too late mitigate. Assessments toxicological risk consist what Sheila Jasanoff calls “sociotechnical imaginar...
