Holiday and festival celebrations are a unique form of cultural expression. Physical activities associated with cultural traditions offer the perfect opportunity for physical educators to integrate interdisciplinary teaching in their programs. This article focuses on the application of a multicultural perspective by introducing 12 station tasks…

To test the hypothesis that social rearing may induce malleability, socially reared and socially isolated mallard duck, "Anas platyrhynchos," embryos and hatchlings were exposed to the maternal call of a chicken, "Gallus gallus domesticus," until 48 h after hatching. The hatchlings were then tested with the chicken call versus…

Gottlieb promoted the value of a developmental psychobiological systems approach to the study of human development. This approach recognizes the importance of comparative, animal-based research to advancing our understanding of the complexities and dynamics of the process of development. The major contribution of animal developmental studies is…

Across the United States, today's farm operators face continuing challenges from global competition, increasing production costs, changing technology, increased regulations, scarce resources, and lower profit margins. To face these challenges, farm operators need to gather and utilize information allowing them to make informed decisions. Several…

"Science Briefs" summarize the findings and implications of a recent study in basic science or clinical research. This Brief summarizes the findings and implications of "Moderate Fetal Alcohol Exposure Impairs the Neurogenic Response to an Enriched Environment in Adult Mice" (I. Y. Choi; A. M. Allan; and L. A. Cunningham). Observations of mice…

Where does cellular respiration take place? How does a plant make food and in turn use the food to produce its own energy? Do animals carry on this process also? To help students answer these and other questions, have them build a model leaf, plant cell, and animal cell. This hands-on project allows students to see and manipulate the reactants and…

Two experiments with the inductive generalization procedure tested whether 16- and 20-month-old infants understand that animals and not vehicles follow a rational path to reach a goal. Infants were tested with four different events and the model exemplar was either an animal or ambiguous block. Results showed that infants at 20 months of age, but…

The aim of this study, carried out in association with beef cattle producers, was to explore the capacity of farms to adapt, from a techno-conomic point of view, to both structural changes in consumer demand for beef products and market disruptions (sudden drop in beef consumption due partly to media coverage of bovine spongiform encephalopathy…

The nucleus basalis magnocellularis (NBM) is known to be involved in the memorization of several conditioned responses. To investigate the role of the NBM in fear conditioning memorization, this neural site was subjected to fully reversible tetrodotoxin (TTX) inactivation during consolidation in adult male Wistar rats that had undergone fear…

Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance…

Matrix metalloproteinases (MMPs) are a family of extracellularly acting proteolytic enzymes with well-recognized roles in plasticity and remodeling of synaptic circuits during brain development and following brain injury. However, it is now becoming increasingly apparent that MMPs also function in normal, nonpathological synaptic plasticity of the…

This article describes a phenomenological study of the artistic creations of bird nests by four school-aged children to illuminate their internal experiences of attachment. The author analyzed qualitative data from in-depth interviews pertaining to two-dimensional and three-dimensional artistic representations of a bird's nest and a family of…

Rats in a Pavlovian situation were trained under three different reward schedules, at either a 30 s or a 90 s intertrial interval (ITI): Consistent reward (C), 50% irregular reward (I), and single alternation of reward and nonrewarded trials (SA). Activity was recorded to the conditioned stimulus (CS) and in all 10 s bins in each ITI except the…

This instructional packet is one of 14 school environmental education programs developed for use in the classroom and at the Dahlem Environmental Education Center (DEEC) of the Jackson Community College (Michigan). Provided in the packet are pre-trip activities, field trip activities, and post-trip activities which focus on the characteristics and…

Explains a teaching activity designed to help students develop an appreciation of the role of animal control officers in the community and the importance of licensing their pets. Includes playing instructions, reproducible game cards and a game board, and a supportive statement from the director of a state humane society. (TW)
