A Systematic Plan for Managing Physical Collections at the University of Arizona Libraries

To address the lack of space for continued expansion of the collections, the University of Arizona Libraries have developed a systematic process and timeline for the ongoing management of the physical collections of information resources. This article discusses the evaluative criteria and parameters for deselection that were developed and demonstrates how they were integrated into a 5-year plan for managing the collections. The process was designed to have the least negative impact on our customers while allowing for the flexible use of physical space. The article will also highlight the successes and challenges of developing and implementing the plan.     

The effects of conscious processing on golf putting proficiency and kinematics

Abstract

Researchers have suggested that skill performance deteriorates when people try to exert conscious control over automatic actions. Unfortunately, little is known about the effects of different types of conscious processing on skilled performance by expert athletes. We conducted two experiments to address this issue. Experiment 1 investigated the influence of a specific form of conscious control (making technical adjustments to a stroke) on the putting skills of expert golfers. The expert golfers maintained putting proficiency (i.e. number of putts holed) when making technical adjustments. However, this form of conscious processing altered the timing and consistency of golfers' putting strokes. Experiment 2 compared the influence of technical adjustments and conscious monitoring (paying attention to the execution of the stroke) on expert golfers' putting skills. Technical adjustments had no disruptive influence on expert golfers' putting proficiency but did reduce the consistency of their strokes. However, conscious monitoring was found to impair putting proficiency. The implications of the work for theory and future work are discussed.     

Rats show preference for delayed rewards on the radial maze

Rats on an eight-arm radial maze chose between four arms on which a small reward could be obtained after a short delay and four arms on which a larger reward could be obtained after a longer delay. Experiments 1 and 2 showed that rats preferred the long-delay, large-reward arms over the short-delay, small-reward arms. This preference was particularly marked when the arms were made into enclosed alleys. Experiment 3 showed that this effect was not produced by a preference for staying in enclosed alleys. We argue that the rats endured longer delays to obtain larger rewards when fear of predation was minimized.
