The authors agree with P. L. Ackerman, M. E. Beier, and M. O. Boyle (2005; see record 2004-22408-002) 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. ...

PURPOSE The aim of this study was to compare the durability and retention of 4 types of attachments placed over computer aided design/computer aided manufacturing (CAD/CAM) titanium bars when subjected to different pH conditions.

The story is a familiar one: a young person drowns, but members of his or her family insist that the deceased was a “good swimmer.” Now, researchers from the Mayo Clinic think they may have found a genetic component to this unlikely tragedy. The researchers identified a new mutation in a gene associated with long-QT syndrome (LQTS) in a young female drowning victim (Ackerman MJ, Tester DJ, Cobu...

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 ...
