We examined the impact of self-controlled knowledge of results on the acquisition, retention, and transfer of anticipation timing skill as a function of random and blocked practice schedules. Forty-eight undergraduate students were divided into experimental groups that practiced under varying combinations of random or blocked as well as self-controlled or yoked practice conditions. Anticipation...

The aim of this study was to evaluate the effects of various practice schedules on learning a novel speech task. Forty healthy Cantonese speakers were asked to learn to produce a Cantonese phrase with two target utterance durations (2500 and 3500 milliseconds). They were randomly assigned to one of four learning conditions, each completing a different practice schedule, namely Blocked only, Ran...

Promoting student involvement in planning has become best practice in the field of transition. Research documents the positive impact of such efforts on greater student involvement. Research also suggests that promoting student involvement results in greater student self-determination, but a causal link has not been established. This study used a randomizedtrial, placebo control group design to...

A literature review was conducted on the effectiveness of activity schedules. Twenty three studies that a) were peer-reviewed, b) were experimental, c) implemented activity schedule as a primary intervention, d) incorporated multiple activities, and e) aimed to teach learners to self-manage individual schedules were included in the review. The results demonstrated the effectiveness of activity ...

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...

A new business model for scholarly journals, open access, has gained wide attention recently. An open-access journal’s articles are available over the Internet free of charge to all readers; revenue to cover publication costs comes from authors’ fees. In this paper, we present a model of the journals market. Drawing upon the emerging literature on two-sided markets, we highlight the features di...

Customary charges have had significant impacts in determining reasonable prices under the historic Medicare physician payment system. This article contains new, comprehensive information on customary charges as well as data aggregated at the physician level. These baseline data have some important policy implications, such as the study findings, that indicate that the Medicare fee schedule is l...

Due to the importance of training, many scientists have studied effective training schedules, and they have compared distributed practice schedules to massed practice schedules. Most of the results consistently show that a distributed practice schedule outperforms a massed practice schedule in a retention test, because of the spacing effect in human memory. This result may lead new scientists w...
