The diagnosogenic (semantogenic) theory for the onset of stuttering was initially proposed by Wendell Johnson in the early 1940s. It suggested that calling attention to a child’s normal hesitations (repetitions) could precipitate stuttering (Bloodstein, 1987). Some of the evidence that Johnson used to support this theory (e.g., certain tribes of American Indians, in which there appeared to be n...

The genetic analysis of spermatogenesis in Drosophila melanogaster has led to the identification of several genes that control the onset of meiosis, spermatid differentiation, or both. We described two tightly linked and nearly identical homeobox genes of the TGIF (TG-interacting factor) subclass called vismay and achintya that are essential for spermatogenesis in Drosophila. In flies deficient...

Most studies tnat-examirie·,atUtudes .atuLcoehavfo:r 'of';:blackstoward mass media emphasize the differences between their attitudes and behaviors and those of whites. Such studies implicitly assume a relatively homogeneous black perspective. In contrast, this study explores differences among black adults in their attitudes and behavior towards television and the social processes accounting for...

The data were collected from 1992 to 2009 in Burri, White Boni and Black Boni sheep maintained at the Regional Research Station in the Central Highlands of Yemen. Data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. The least square means for body weights (BW) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

We present a classification of all global solutions (with Lorentzian signature) for any general 2D dilaton gravity model. For generic choices of potential-like terms in the Lagrangian one obtains maximally extended solutions on arbitrary non-compact two-manifolds, including various black-hole and kink configurations. We determine all physical quantum states in a Dirac approach. In some cases th...
