The course "Management of Fluid and Electrolyte Disorders" is an applied physiology course taught using lectures and paper-based cases. The course approaches fluid therapy from both basic science and clinical perspectives. While paper cases provide a basis for application of basic science concepts, they lack key components of genuine clinical…

The study of the human form is fundamental to both science and art curricula. For vertebrates, perhaps no feature is more important than the skeleton to determine observable form and function. As Leonard da Vinci's famous Proportions of the Human Figure (Virtruvian Man) illustrates, the size, shape, and proportions of the human body are defined by…

Previous experiments have demonstrated that the simultaneous presentation of independently established discriminative stimuli can control rates of operant responding substantially higher than the rates occasioned by the individual stimuli. This "additive summation" phenomenon has been shown with a variety of different reinforcers (e.g., food,…

Two experiments with pigeons investigated the effects of contingencies between interresponse times (IRTs) and the transitions between the components of 2- and 4-component chained schedules (Experiments 1 and 2, respectively). The probability of component transitions varied directly with the most recent (Lag 0) IRT in some experimental conditions…

This article presents a tentatively "balanced" view (i.e., midway between lean and rich interpretations) of pointing behavior in infants and apes, based upon the notion of intentional reading of behavior without simultaneous attribution of unobservable mental states. This can account for the complexity of infant pointing without attributing…

This article examines problems that may arise when addressing liability resulting from the genetic modification of microbes, animals, and plants. More specifically, it evaluates how uncertainties relating to the outcomes of these biotechnological innovations affect--or may affect--the courts' application of the reasonable foreseeability…

In this article, we concentrate upon the lifeworld resources that comprise the funds of knowledge for children living in a rural community in the southeastern United States. Through interview conversations with a group of third grade children, we identified three lifeworld resources--interdependence, garbage dumping, and feral dogs--that rural…

There are moments in outdoor education that can only be described as magical. These are times when the wider world mirrors human stories with an uncanny synchronicity, as if choreographed by an unseen hand. Often the only thing people can really do is try and stay out of the way. In the author's own work, the footsteps moving through such magical…

Previous in vitro studies have characterized the electrophysiological properties and molecular events associated with long-term potentiation (LTP), but as yet there are no in vivo data from molecular-level dissection that directly identify LTP as the biological substrate for learning and memory. Understanding whether the molecular pathways…

In area CA1 of hippocampal slices, a single 1-sec train of 100-Hz stimulation generally triggers a short-lasting long-term potentiation (S-LTP) of 1-2 h. Here, we found that when such a train was applied 45 min after application of the small conductance Ca[superscript 2+]-activated K[superscript +] (SK) channel blocker apamin, it induced a…

In five experiments using rats, we investigated compound context-flavor conditioning. The subjects were allowed to spend time in the target context, where they had access to a flavored solution (either citric acid or saccharine) before receiving an injection of LiCl. Context aversion was then assessed by using a blocking procedure. When the flavor…

The author's encounter with a live owl and her purchase of a Peruvian folk art gourd inspired a new interdisciplinary experience for the author's fourth grade students. In this article, she describes how her students explored owls through clay sculpture. (Contains 2 resources and 1 online resource.)

Background: Although many studies have now demonstrated that threat information is sufficient to change children's beliefs and behaviours towards novel animals, there is no evidence to suggest that it influences the physiological component of the fear emotion. Methods: An experiment is reported in which children (N = 26) aged between 6 and 9 were…

Insects and rodents in education facilities can cause structural damage, and they carry diseases that threaten food safety and the health of students and employees. To effectively prevent infestations and manage pests in a safe and eco-sensitive manner, many schools turn to integrated pest management (IPM) programs that emphasize environmentally…

This article discusses regeneration which is actually the dream of a scattering of biologists working in a relatively unheralded field called regenerative medicine. They hope to learn how other animals make whole their damaged parts, recreating complete working organs and appendages just as they did as embryos, but swiftly, and on a scale that…
