Publication is a critical focus in the scientific world. Societies
have publication wings. There is a large commercial publication
business that earns nearly $20Bn/year with a third being
profits. The Guardian published a revealing article about the
publication world which this blog has offered comments.
and critical thinking when reading
This blog is on record for supporting the idea of “open access”
and questioning the viability of “rating” journals based on
citations in the internet age [it is like mindless “likes” in
Been a following of Deming’s articles on Applied Statistics
for decades. He is in the middle of an important series on
limits of detection. I just received a water analysis report
and have received blood and urine medical reports that refer
to one or another of these. These articles are important and
significant for all of us. We should know and use these terms
One of the types of questions I ask in some interviews
concerns gas cylinder set-up and use. Articles in LC/GC
often reveal solid scientific thinking to answer questions
in this area.
ROBERT MAXWELL AND PROFITING ON SCIENCE
Although the ACS continues its efforts to
profit center, most of the members do not realize what
is going on in the publication business. This Guardian
article goes into details what the ACS publications
division might be emulating.
Should we not ask questions to make more science, often
paid for via taxes, available free online?
SCIENCE AND THE LIMITS OF DETECTION
SOURCE: S. N. Deming, Amer. Laboratory June/July 2017
Deming teaches in this article L(D) the limit of detection, which
he points out is different than the smallest amount of
analyte that can be detected or the limit of quantitation (appearing
in future articles.).
He points out:
- false positive risk needs to be appropriate for the application.
[drug testing example]
- in a plot of a calibration curve with a non-zero intercept, L(D)
the limit of detection is the amount of analyte that yields a
signal outside the error of the false negative.
These comments are often not brought out in many classes.

What I like about Hinshaw is that he does a fishbone diagram
to assess a wide variety is issues that could come up in
working with a common analytical tool.
