    Helping children think: Gaze aversion and teaching

    No full text
    Looking away from an interlocutor's face during demanding cognitive activity can help adults answer challenging arithmetic and verbal-reasoning questions (Glenberg, Schroeder, & Robertson, 1998). However, such `gaze aversion' (GA) is poorly applied by 5-year-old school children (Doherty-Sneddon, Bruce, Bonner, Longbotham, & Doyle, 2002). In Experiment 1 we trained ten 5-year-old children to use GA while thinking about answers to questions. This trained group performed significantly better on challenging questions compared with 10 controls given no GA training. In Experiment 2 we found significant and monotonic age-related increments in spontaneous use of GA across three cohorts of ten 5-year-old school children (mean ages: 5;02, 5;06 and 5;08). Teaching and encouraging GA during challenging cognitive activity promises to be invaluable in promoting learning, particularly during early primary years

    Integrated Doherty power amplifiers for satellite systems: Challenges and solutions

    No full text
    This paper discusses the possible exploitation of the Doherty technique, very popular in mobile communication applications, in the design of integrated power amplifiers for satellite systems. The work focusses on the advantages and disadvantages of Doherty power amplifiers compared to other solutions, by presenting the specific features of the Doherty design in the framework of the very demanding requirements of space applications. In particular, satellite applications in the millimetre-wave spectrum are strong candidates for utilising integrated Doherty power amplifiers. In that context, the intrinsic limitation of the Doherty technique at millimetre-wave frequencies will be discussed, presenting solutions in terms of technology and design to improve gain, bandwidth, efficiency, and linearity. Some state-of-the-art examples are shown and analyzed, emphasizing the most relevant results achieved so far

    K-band combined GaAs monolithic Doherty power amplifier

    No full text
    This paper presents the design, simulations, and measurements of a 35 dBm K-band Doherty power amplifier, fabricated on 0.15μm GaAs monolithic technology of Qorvo. The power amplifier is based on combining on-chip two Doherty modules with a matching power combiner. To demonstrate the power scaling and gain a better insight into the design, the single Doherty module has been fabricated and characterized as well. The Doherty output matching is designed for maximizing the bandwidth and minimizing the components count, with the output capacitance of the active devices determining the impedance inverter impedance. The combined Doherty shows an output power of 35 dBm at 24 GHz, that is almost exactly 3 dB larger than the single Doherty module power module, and with a 6 dB OBO efficiency of 27%, and a gain of 11.5dB. It compares well with the state of the art, representing the highest power GaAs Doherty at similar frequencies

    First paragraph: Welcome to the summer 2022 edition of Scottish Educational Review. The Journal was founded in 1968 and retains a unique place in the Scottish educational landscape while today serving an international audience. This edition is distinguished by being the very first to be published online and open access with the publishing house Brill. This new location and mode of publishing opens a new chapter in its story. As editors, we are excited by the possibilities of this new partnership which broadens our reach to a truly worldwide community of researchers and educational professionals. It is our earnest hope and expectation that this new accessibility and extended international influence will encourage and continue to support research collaboration within Scotland and beyond

    Doherty\u27s Legacy

    No full text
    William H. Doherty was an American electrical engineer, best known for his invention of the Doherty amplifier. Born in Cambridge, Massachusetts, in 1907, Doherty attended Harvard University, where he received his bachelor\u27s degree in communication engineering (1927) and his master\u27s degree in engineering (1928). He then joined the American Telegraph and Telephone Company Long Lines Department in Boston. He remained there for a few months before joining the National Bureau of Standards, where he researched radio phenomena. Doherty joined Bell Telephone Laboratories (now Bell Labs) in 1929 and, while there, worked on the development of high power radio transmitters that were used for transoceanic radio telephones and broadcasting
