Hello; Have not looked at your link. My have the same sort of stuff I had to digest when still teaching. Lots of in service hours I logged in every year and plenty on the effects of corporal punishment as they were taking it away as a discipline tool. Note- For what it is worth, I did not much like to paddle students. However when it was taken away there was no effective discipline offered in it's place.
I could go on a long time about the subject but will briefly touch on he bullies. Back when I could paddle there was not much the bullies could get away with at my middle school (Or high schools for that matter). Two or three of the teachers pretty much always carried a paddle during recess and lunch period. If we saw any such activity we would settle it right then and there. In fact not much ever happened during that time. It only took getting the attention of a few at the start of the school year, after only a few times the paddles were needed. The smaller more timid children made sure to keep me or Mr. F in sight when out and about during non-class times and we kept an eye out on all of them.
By the time the paddle was gone the rough kids had very little check on their behavior. That was when I personally saw a rise in undesireable behavior through out the schools including the bullies.
I get that you are not likely to accept my personal experience as worth anything but there it is.
