We made the following assumptions: (1) the responses of pairs of units, or of a given unit at two different times, were conditionally
independent given the stimulus; (2) the expected firing rate of unit in time bin was a function of the recent history of stimulation — that is, of the spectrogram segment (where is the full sound spectrogram, is frequency, and is a history index, covering 20 bins — i.e., 100 ms); and (3) the observed firing rate of unit at time,, was the result of an inhomogeneous Poisson process, with for some function.
1) Charities spend their income on necessities, such as food and utilities, which ever - so - slightly re-orients our economy toward recession - resistant products, rather than luxuries 2) Charities spend their money quickly, but on
independent schedules, making for a smoother
stimulus effect on the economy 3) Charities make purchases tax - free, meaning that $ 1 spent by a charity generates a full $ 1 of private economic activity; furthermore, much of those tax revenues are recovered as income tax on the grocery stores, utility companies, etc. that might not have received that income otherwise 4) Charitable

giving restores your say - so 5) Charitable donations are tax deductible, meaning you keep those tax dollars in your local community 6) Charitable donations provide the funds necessary for volunteers to serve the needy, thus
giving «the average citizen» a chance to meet and interact with the needy, breaking down stereotypes
