PESO -- Circular Waterfall 2021 & an enablement.

[P. J. Alling]

I guess this is kind of and enablement post as well as a PESO. Ever 
since the destruction of my funky, 60's vintage Sigma* 12mm semi 
circular fish eye, which was pretty much a full frame fisheye on APS-C 
digital, I've been on the lookout for a good deal on a fisheye lens to 
use on my K-3 and K-5II.  A couple of weeks ago I was able to get a Like 
New in Box copy of the Pentax DA 10-17mm Fish Eye zoom and decided to 
test it out at Chatfield Hollow State Park, on their Circular Water 
Feature.  It was bitterly cold but the lens and camera didn't disappoint 
me, even if the rendering software did.


I've discovered something really annoying about DXO Optics Pro 9.  When 
applying corrections to the afore mentioned 10-17mm, it seriously 
defishes it by default.  I don't know how to tell it to not do this 
except by removing the lens correction module.  I'm going to contact DxO 
and ask them if they understand the point of a fish eye lens, because 
they apparently don't.


I'm too tired right now to try how to figure out how to get the full 
fish eye effect, so you'll just have to put up with the defished image 
for now.


http://webster26.epizy.com/peso/PESO--CircularWaterfall2021.html

Equipment: Pentax K-3 w/PENTAX DA 10-17mm f/3.5-4.5 ED (IF) Fish-Eye Zoom.

As usual comments are welcome but may be totally ignored.

* It wasn't labeled Sigma but that's who made those lenses, Waterhouse 
stops and all.

This is a #@%^&*+ dumb article! :-)
(And full of bovine scatology.)


On a serious note, this is a questionable quality article relying on 
questionable (IMHO - incorrect!) research results (conclusions).


I have discussed this article yesterday and today with a friend who 
actually works in medical research. We guessed that most likely the 
journalist was given an assignment to write something by the deadline 
(possibly on the subject), so she googled something and came up with 
some superficial conclusions, without much of critical thinking, and 
got paid for that mumbo-jumbo.


Besides having some wrong conclusions, what also adds to that 
impression is that the journalist does not seem to demonstrate 
understanding of how scientific research (publications) works: One of 
the referenced papers is a manuscript at the stage when it was 
submitted for publication. I actually have doubts if the journalist 
has actually verified whether it was published in a peer-reviewed 
journal. (I checked, it was.) [*]



Now, about the underlying research:
At least the first research article quoted by the journalist is flawed.
(I am reluctant to analyze in detail all of them.) [**]

The biggest problem about it is non-representative choice of the study 
participants. They had three studies, but all of them used college 
students taking psychology courses:
"A total of 43 participants (30 women) were recruited from 
introductory psychology courses at a small liberal arts college <...> 
Their ages ranged from 18 to 22 years ..."
"A total of 49 participants (34 women) were recruited from 
introductory psychology courses at a small liberal arts college <...>. 
Their ages ranged from 18 to 22 years ..."
"Participants were 126 college students aged 18–38 years (86 women 
<...>) enrolled in an introductory psychology course at a small 
liberal arts college."


That is a very narrow category of the study participants, with a 
higher than average educational/cultural/social/... level.
I am sure if they took people from other socio-demographic groups, 
especially from the lower social levels, they would've seen quite 
different results.



To summarize, the study reported is not necessarily representative for 
the entire society. And the authors fail to acknowledge that fact.

(If I were the referee, I would've pointed this out, and would not have
recommended this article for publication unless a clear explicit 
statement about that serious limitation is made. - I've done similar 
recommendations on multiple occasions - in my field.)



This is a good example of how a [wrong] message from unscrupulous 
scientists can be amplified by low-quality journalists. This type of 
situations undermine the role of science in our society (leading to a 
wide-spread skepticism toward the science in the society).


My apology for being a party pooper... :-)


=
[*]
Let me clarify this point for those who might not be familiar with how 
scientific publications work. The author(s) submits a manuscript to 
the editor for publication. The editor takes a look - to determine who 
would be good reviewers, and sends it to those for review.  Based on 
the reviewers' comments and recommendations, the editor makes a 
decision: to publish, to reject, or to give an opportunity to make 
improvements, in which case, the article can go through an additional, 
similar, round of review.
I've refereed many manuscripts. A significant portion of those were 
not suitable for publication without significant revision. Some of the 
manuscripts should have never been published (and usually they weren't).


So, the bottom line is that a peer review is an important tool to weed 
out improper articles. So if an article hasn't passed it, - its 
results and conclusions might not be reliable.

However, it is important to recognize that the peer-review is not a
guarantee. Moreover, there are peer-reviewed publications that are 
wrong. Some of those should not have passed through the peer-review, 
others were found to be wrong by the subsequent studies stimulated by 
them. The latter is a normal scientific discovery process.)


[**] I am not claiming all conclusions are wrong, - but even some of 
them being wrong make the entire article wrong.



Cheers,

Igor

(If I were the referee, I would've pointed this out, and would not have
recommended this article for publication unless a clear explicit statement 
about that serious limitation is made. - I've done similar recommendations 
on multiple occasions - in my field.)



This is a good example of how a [wrong] message from unscrupulous 
scientists can be amplified by low-quality journalists. This type of 
situations undermine the role of science in our society (leading to a 
wide-spread skepticism toward the science in the society).


My apology for being a party pooper... :-)

Let me clarify this point for those who might not be familiar with 
how scientific publications work. The author(s) submits a manuscript to 
the editor for publication. The editor takes a look - to determine who 
would be good reviewers, and sends it to those for review.  Based on 
the reviewers' comments and recommendations, the editor makes a decision: 
to publish, to reject, or to give an opportunity to make improvements, in 
which case, the article can go through an additional, similar, round of 
review.
I've refereed many manuscripts. A significant portion of those were not 
suitable for publication without significant revision. Some of the 
manuscripts should have never been published (and usually they weren't).


So, the bottom line is that a peer review is an important tool to weed out 
improper articles. So if an article hasn't passed it, - its results and 
conclusions might not be reliable.

However, it is important to recognize that the peer-review is not a
guarantee. Moreover, there are peer-reviewed publications that are 
wrong. Some of those should not have passed through the peer-review, 
others were found to be wrong by the subsequent studies stimulated by 
them. The latter is a normal scientific discovery process.)


[**] I am not claiming all conclusions are wrong, - but even some of them 
being wrong make the entire article wrong.



Cheers,

Igor
