Message 8169:

I used to work for a Juvenile Hall here in California and you wouldn't believe what things we came across. The worst part is that the employees were somehow involved in the contraband ring. The most we found were sacks of weed. Being that certain searches are not allowed anymore or pepper spray there is a lot that we missed coming in and leaving the premises.


This was in response to Message 8149 in which a UWP student was recounting the contraband discovered in a creative measure the student was doing for corrections. I'm delighted that you are all benefitting in this way from our cross-country sharing.

Message 8168:

Robert and Kaneetria you both hit it right on the head. No correct interpretations! I feel the same way as you both do about us having free will. We all as human beings feel and think differently. If we didn't this world would be a black and white boring TV. show from the 50's. Sharing different interpretations is exciting and brings on a good debate. It also teaches us different things that we might have not noticed before.


Elva, this is a good statement in your own words of the importaance of recognizing the subjective component of interpretation. All interpretations have this problem.

Message 6500:

In the case study of the cement in the spinal cord, doctors need to set up a regression. "A regression is a form of statistical technique." This will allow the doctors to see and compare "general patterns" of the pain before and after the cement is injected in the spinal cord. The scale can range from 0 to 10, using only even numbers. Zero would stand for completely pain free; where as numbers two through ten would vary depending on the description given by the patient. After all surveys are in the doctors can separate the patients by gender and age. Then the patients can be separated by the number they rate their pain. When all the numbers are in, the doctors could have a better look at the pain affecting each patient. It can also given them a look at the possibility that the pain could regress. If it regresses who regresses faster man or woman, what age rage and how bad are questions that might be answered.


Elva, You're right on defining the way in which pain is traditionally measured, but I'd like you to recognize and state the actual problems with that type of measurement, i.e., that it's subjective, subject to statements of lesser pain just because over time there is regression toward the mean, and the problem with using such measurement alone to decide on a treatment's efficacy. Your use of the term regresses is inaccurate. Go back to the article for a definition.

Message 6501:

The graph posted in the article, Living Alone, does not show the whole picture. It showed that 26.8% of the United States population lives alone. What exactly is their definition of alone? Giving us their meaning of alone would help us, the reading public, comprehend how many Americans actually live alone, with no one to count on and no living relatives a few miles away to run home to when one is truly lonely.

When one takes a closer look at the article, one notices that those 26.8% "are either elderly or sick." Yet, the article states that it is extremely hard to actually calculate how many disabled, mentally ill or severely sick Americans are really out there living alone. The graph needed to be further developed and more accurate.


Good points made on definition of variable and the difficulty of measurement with a socially constructed variable.
