The Bottom Line for Education and Training     

Melanie F. Sikorski  Richard P. Niemiec  Herbert J. Walberg 《Performance Improvement Quarterly》1989,2(4):42-50

Because business and industry training has become a major economic investment for the companies that support it, training managers are increasingly called upon to demonstrate that their interventions are not only effective but also cost-effective. This article describes a cost-effective methodology. It points out how cost-effectiveness differs from cost-benefit analysis. The technique combines meta-analytic and simple accounting procedures to yield an index of relative cost-effectiveness of training interventions. Using examples from the schools and corporate training, the authors demonstrate how the analysis can be applied to a large variety of training situations.  相似文献   

Knee extensor and flexor torque development with concentric and eccentric isokinetic training     

Miller LE  Pierson LM  Nickols-Richardson SM  Wootten DF  Selmon SE  Ramp WK  Herbert WG 《Research quarterly for exercise and sport》2006,77(1):58-63

This study assessed muscular torque and rate of torque development following concentric (CON) or eccentric (ECC) isokinetic training. Thirty-eight women were randomly assigned to either CON or ECC training groups. Training consisted of knee extension and flexion of the nondominant leg three times per week for 20 weeks (SD = 1). Eccentric training increased ECC knee extension and flexion peak torque more than CON training. The ECC group improved acceleration time and time to peak torque with ECC movements versus the CON group. Slow-velocity ECC isokinetic training yielded greater ECC and similar CON torque development gains versus CON training over the course of 20 weeks in young women.  相似文献

Frequency-coordinate vector diagram     

Philip F. Ordung  Herbert L. Krauss 《Journal of The Franklin Institute》1951,251(3):343-350

From the standpoint of circuit synthesis as well as for a fundamental comprehension of circuit behavior, it is desirable to be able to visualize the response of a circuit over an extended frequency range by means of a geometrical construction. Mathematically, the response of a circuit can be expressed with the La Place transform theory as a function of the complex frequency variable, p = α + jωw, in which a is the decrement and ω is the “real” angular frequency. Physically, the nature of the real-frequency response is usually not discernible by casual inspection of the mathematical function. This paper develops a means of visualizing this frequency response readily through the construction of a vector diagram from the response function.  相似文献
