Quantity and Quality of Physical Medicine and Rehabilitation Clerkships in US Medical Schools.

OBJECTIVE: The purpose of this study was to address two underreported issues in undergraduate physical medicine and rehabilitation medical education: quantity and quality of physical medicine and rehabilitation clerkships in US medical schools. DESIGN: A multimethod sequential design was used to evaluate the curricula of US medical schools. Quantity (N = 154) of physical medicine and rehabilitation clerkships was assessed by counting the number of required, selective, and elective clerkships in each medical school. Quality (n = 13) was assessed by conducting a thematic analysis on physical medicine and rehabilitation clerkship curricula to identify learning objectives. These objectives were then compared with learning objectives in a model standard. RESULTS: Whereas few medical schools required a physical medicine and rehabilitation clerkship, most offered elective rotations in physical medicine and rehabilitation. Most medical schools only included 6 of the 12 model standard learning objectives. Medical schools also included 29 learning objectives not present in the model standard. CONCLUSIONS: Physical medicine and rehabilitation clerkships are not underrepresented but are underemphasized, in undergraduate medical schools. Furthermore, these clerkships use inconsistent learning objectives. Thus, findings suggest the need to draw attention to physical medicine and rehabilitation clerkships by offering them as selectives and to develop a list of standardized learning objectives. This exploratory study developed such a groundbreaking list and invites the physical medicine and rehabilitation community to test it.

Classical conditioning of proboscis extension in harnessed Africanized honey bee queens (Apis mellifera L.).

Experiments are reported on learning in virgin Africanized honey bee queens (Apis mellifera L.). Queens restrained in a "Pavlovian harness" received a pairing of hexanal odor with a 1.8-M feeding of sucrose solution. Compared to explicitly unpaired controls, acquisition was rapid in reaching about 90%. Acquisition was also rapid in queens receiving an unconditioned stimulus of "bee candy" or an unconditioned stimulus administered by worker bees. During extinction the conditioned response declines. The steepest decline was observed in queens receiving an unconditioned stimulus of bee candy. These findings extend previous work on learning of Afrianized honey bee workers to a population of queen bees.

Development of an ethanol model using social insects: III. Preferences for ethanol solutions.

Experiments are designed to assess whether free-flying honey bees have an aversion to an ethanol solution when given a choice between targets containing an ethanol solution in sucrose or sucrose only. Animals given a choice between a 1% ethanol solution and sucrose only show no aversion to the ethanol solution either in acquisition or extinction. Honey bees given a choice between a 5% ethanol solution and sucrose only show no differences in the initial choice of targets but some ees do switch over to the sucrose-only target. Performance during extinction indicates that bees landed on the previously reinforced sucrose-only target more than the target previously containing the 5% ethanol solution. An experiment in which bees were given a single 5%, ethanol target showed that of 20 bees, 11 returned for the entire 12 trials of the experiment. All bees returned at least 6 times to the 5% ethanol target. Additional experiments were run on harnessed foragers in a palatability study of alcoholic beverages consumed by humans. The results of the palatability experiment indicate that in general, bees prefer more sweet drinks with less alcohol.
