The authors agree with P. L. Ackerman, M. E. Beier, and M. O. Boyle (2005) that working memory capacity (WMC) is not isomorphic with general fluid intelligence (Gf) or reasoning ability. However, the WMC and Gf/reasoning constructs are more strongly associated than Ackerman et al. (2005) indicate, particularly when considering the outcomes of latent-variable studies. The authors’ reanalysis of ...

What follows are the perceptions of two individuals-a patient and a highly respected medical oncologist who did not participate in the care of this patient but read the patient's essay. We encourage readers to share their thoughts about these essays in correspondence. Barrie E. Cassileth, Ph.D. Department of Integrative Medicine, Memorial Sloan-Kettering Cancer Center, New York, New York A. Ber...

When building the robot for outdoor competition the designer can choose from a variety of chassis. The differential drive and Ackerman steering drive are among the most popular. The paper describes our experiences with the custom built chassis that uses Ackerman steering principle together with independently driven back wheels. The chassis represent the base of Bender II mobile robot, used in R...

Establishing the journal, Dermatology Practical & Conceptual (DPC), has been a tremendous challenge for us. Previously named Dermatopathology Practical & Conceptual by Bernie Ackerman, who was the visionary founder, DPC became more and more relevant under the editorship of Drs. Kittler, Zalaudek, Marghoob and Marchetti. When the journal became the official organ of the International Dermoscopy ...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

using an electric differential (ed) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. despite its reported successes and advantages, the ed has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. in this paper, an electric differenti...
