How Johnny Can\u27t Learn
Johnny\u27s learning problems have troubled his parents and haunted his teachers since the first group of students met in the pervasive little red schoolhouse. Because of Johnny\u27s academic inadequacies, his teachers are admonished by public officials; teachers censure Johnny\u27s parents; Johnny\u27s parents criticize his lack of motivation, capability or interest; and Johnny, through his frustrations, condemns all society for its insensitivity and lack of understanding. This description includes the Johnny who is black. This Johnny responds to his society in a similar way, but his problems are more intense. His relationships with his environment are more complex. His learning problems are more confounding. (Ashmore, Hayakawa, Reissman, Woodson
Howard, George Elliott (1849-1928)
George Elliott Howard, a distinguished social scientist trained initially in history, rose to the presidency of the American Sociological Society in 1917. Howard earned the A.B. in 1876 at the University of Nebraska. Following two years of advanced study in Germany, Howard joined the Nebraska faculty in 1879. Howard\u27s most prominent Nebraska student from this period, Amos Griswold Warner, later wrote American Charities (1894) - a standard classic in the field. Howard was named to the prestigious First Faculty of Stanford University in 1891
The Reliability of Electromyographic Normalization Methods for Cycling Analyses
Electromyography (EMG) is normalized in relation to a reference maximum voluntary contraction (MVC) value. Different normalization techniques are available but the most reliable method for cycling movements is unknown. This study investigated the reliability of different normalization techniques for cycling analyses. Twentyâfive male cyclists (age 24.13 ± 2.79 years, body height 176.22 ± 4.87 cm and body mass 67.23 ± 4.19 kg, BMI = 21.70 ± 2.60 kgâmâ1) performed different normalization procedures on two occasions, within the same testing session. The rectus femoris, biceps femoris, gastrocnemius and tibialis anterior muscles were examined. Participants performed isometric normalizations (IMVC) using an isokinetic dynamometer. Five minutes of submaximal cycling (180 W) were also undertaken, allowing the mean (DMA) and peak (PDA) activation from each muscle to serve as reference values. Finally, a 10 s cycling sprint (MxDA) trial was undertaken and the highest activation from each muscle was used as the reference value. Differences between reference EMG amplitude, as a function of normalization technique and time, were examined using repeated measures ANOVAs. The testâretest reliability of each technique was also examined using linear regression, intraclass correlations and Cronbachâs alpha. The results showed that EMG amplitude differed
significantly between normalization techniques for all muscles, with the IMVC and MxDA methods demonstrating the highest amplitudes. The highest levels of reliability were observed for the PDA technique for all muscles; therefore, our results support the utilization of this method for cycling analyses
Synthesis of a Vocal Sound from the 3,000 year old Mummy, Nesyamun âTrue of Voiceâ
The sound of a 3,000 year old mummified individual has been accurately reproduced as a vowel-like sound based on measurements of the precise dimensions of his extant vocal tract following Computed Tomography (CT) scanning, enabling the creation of a 3-D printed vocal tract. By using the Vocal Tract Organ, which provides a user-controllable artificial larynx sound source, a vowel sound is synthesised which compares favourably with vowels of modern individuals
Whither systems biology
Cell biologists are interested in how complexity arises from the interaction of different molecules. However, cells are many orders of magnitude larger than the protein-binding interfaces. To bridge these vast difference in scales, biologists construct hierarchies of organization of cellular structures. I describe how systems biology provides an approach to bridge these different scales
