This paper forms part of a larger study into the nature of singing development in children. The focus here is on an investigation of age-related changes in long-term average spectra (LTAS). Three hundred and twenty children in age groups 4-11 years learned a song. Each child was then digitally recorded singing alone. LTAS curves were calculated from the recordings of each voice and perceived ag...

Scheduling of the transmission of status updates over an error-prone communication channel is studied in order to minimize the long-term average age of information (AoI) at the destination, under an average resource constraint at the source node, which limits the average number of transmissions. After each transmission, the source receives an instantaneous ACK/NACK feedback, and decides on the ...

Economists are often interested in estimating averages with respect to distributions of unobservables, such as moments individual fixed-effects, or average partial effects discrete choice models. For quantities, we propose and study posterior (PAE), where the is computed conditional on sample, spirit empirical Bayes shrinkage methods. While usefulness for prediction well-understood, a justifica...
