Although the Alternative Uses divergent thinking task has been widely used in psychometric and experimental studies of creativity, the cognitive processes underlying this task have not been examined in detail before the two studies are reported here. In Experiment 1, a verbal protocol analysis study of the Alternative Uses task was carried out with a think aloud group (N = 40) and a silent cont...
It was shown by Wiener (1944) that some human a,nti-Rh sera contained incomplete antibodies which combined with but did not agglutinate the corresponding red cells. They appeared to be more avid than agglutinating antibodies, so that, if the two kinds of antibody co-existed in the same serum, the incomplete or blocking antibody might account for failure of agglutination or for a zone of inhibit...
The small-scale roughness properties of the seafloor are increasingly being recognized as critical parameters in determining important processes in physical oceanography. For instance, in situ observations (e.g., Polzin et al., 1997) find that mixing levels are greatly elevated in regions of rough topography. Gille et al. (2000) demonstrate that mesoscale eddy energy tends to be lower in areas ...

Matthias H. Tschöp, MD, fromMunich, Germany, received the American Diabetes Association’s prestigious 2011 Outstanding Scientific Achievement Award. The award was presented at the Association’s 71st Scientific Sessions in San Diego, California in June 2011. The Outstanding Scientific Achievement Award recognizes distinguished scientific achievement in the field of diabetes, taking into consider...
The feasibility of peptide synthesis by four component condensation (4CC) [1] has been demonstrated [2]. In particular the advantages of peptide synthesis by 4CC, namely coupling without carboxyl activation, the possibility of reaction in highly polar media, and the effectively unimolecular nature of the coupling step in such coupling of peptide fragments are being recognized [3]. The unique fe...

Phaeobacter gallaeciensis can antagonize fish-pathogenic bacteria in vitro, and the purpose of this study was to evaluate the organism as a probiont for marine fish larvae and their feed cultures. An in vivo mechanism of action of the antagonistic probiotic bacterium is suggested using a non-antagonistic mutant. P. gallaeciensis was readily established in axenic cultures of the two microalgae T...
We synthesized and tested the biological properties of four fluorescent vasopressin analogs: [1-(2-mercapto)propionic acid]-8-lysine-N6-5-dimethylamino-naphthalene-1-sulfonyl vasopressin (D-MLVP), [1-(2-mercapto)propionic acid]-8-lysine-N6-carboxyfluorescein vasopressin (F-MLVP), [1-(2-mercapto)propionic acid]-8-lysine-N6-2-N-methylanthranilamide vasopressin (MA-MLVP), and [1-(2-mercapto)propio...
The local stellar kinematics of the Milky Way offer a useful tool for studying the rotation curve of the Galaxy. These kinematics – usually parameterized by the Oort constants A and B – depend on the local gradient of the rotation curve as well as its absolute value (Θ0), and the Sun’s distance to the Galactic center (R0). The density of interstellar gas in the Milky Way is shown to vary non-mo...
