Background: Psychopaths are not only antisocial, but also have a callous and unemotional personality profile. This article selectively reviews evidence that psychopathic personality traits are an important factor in understanding and predicting the development of persistent antisocial conduct. Cognitive neuroscience research and more tentative…

Even though philosophical themes in science education have been advocated for several decades, little attention has been paid to how these themes can be contextualized in the teaching of a particular domain of science. The purpose of this paper is to provide an example theoretical framework for applying a philosophical theme, reduction, in…

The prefrontal cortex is involved in the integration and interpretation of information for directing thoughts and planning action. Working memory is defined as the active maintenance of information in mind and is thought to lie at the core of many prefrontal functions. Although dopamine and other neurotransmitters have been implicated, the…

Metabolism, the sum of all chemical reactions within a living organism, is one of the most fundamental concepts presented in introductory microbiology courses. However, it is often difficult for instructors to effectively translate perfunctory diagrams of glycolysis, the Krebs cycle, and the electron transport chain in a way that is meaningful to…

Describes bonding properties that account for the difference in toxicity between hydrogen cyanide and carbon monoxide. Uses the concepts of intermolecular and intramolecular forces in explaining the operation of pressure sensitive adhesives. Gives a definition of a cubic crystal class. (GS)

Describes a student project which requires limited knowledge of Fortran and only minimal computing resources. The results illustrate such important principles of quantum mechanics as the variation theorem and the virial theorem. Presents sample calculations and the subprogram for energy calculations. (GS)

Describes a computer program that teaches the concept of spatial distributions of atoms in a molecule and another program that simulates the kinetic progress of a chemical reaction. (MLH)

Describes a laboratory experiment in which the students prepare an antichap lipstick from basic ingredients and demonstrate solubility relationships between these ingredients and water. (MLH)

Explains using the linear combination of bonding orbitals methods; why two different diagrams are used to represent the molecules when the properties of homonuclear diatomic molecules are being discussed. (GA)

Objects to the idea of treating molecular particles, such as molecules and atoms, as equal in kind to substances when discussing chemical reactions, thus confusing their different roles in the theory of matter. (GA)

Reviews two component systems forming so-called inclusion compounds. (SL)

Reviews the study of molecular shapes and structures. (SL)

Reviews the topic of atomic, molecular, and ionic size. (SL)
