In this article, we review the principal findings on infant categorization from the last 30 years. The review focuses on behaviorally based experiments with visual preference, habituation, object examining, sequential touching, and inductive generalization procedures. We propose that although this research has helped to elucidate the ‘what’ and ‘when’ of infant categorization, it has failed to ...

The silent films of the early 1900s had a huge audience, hearing and deaf, for public entertainment and instruction. The advent of "talkies," however, excluded deaf people from this means of access to mainstream American culture. In response to a new need for both captioned educational and entertainment films for deaf people, Congress passed Public Law 85-905 in 1958, which established Captione...

Coulomb energy calculations for the lowest 0+ , T = 2 state in A = 16 nuclei allow tight constraints on the masses of the lowest 1/2+ , T = 3/2 state in 15O and 15F, and of the 0+ , T = 2 state in 16F.

The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air showers (EAS), including measurements of the EAS particle content on ground which is sensitive to high-energy hadronic interactions. We present the results of several independent measurements of the EAS muon content ...

We use a weak-coupling procedure and results of a shell-model calculation to compute the two-proton separation energy of 19Mg. Our result is at the upper end of the previous range, but 19Mg is still bound for single proton decay to 18Na. We also calculate the 2p decay width.

The development of antisepsis in the late nineteenth and early twentieth centuries revolutionized health care. The time-honored technique of skin preparation is to scrub the entire operative area of the patient for 5 to 7 minutes with a germicidal detergent solution and then paint the region with an antimicrobial solution of either tincture of povidone-iodine (Betadine) or chlorhexidine. Althou...

OBJECTIVE Examination of the vocal function and acoustic analysis in 905 teachers in La Rioja. DESIGN A case control study: 576 cases and 329 controls. PATIENTS 905 teaching staff of La Rioja: 589 female and 316 male. METHODS All teachers filled in a standard questionnaire, ENT and vocal function examination, videolaryngostroboscopy and acoustic analysis with MDVP. RESULTS The prevalenc...
