I finally dropped Feedly

With the recent discussion about (successful?) profiling of voters, I do not want anymore anyone analyzing my reading habits. Feedly’s “Terms and Conditions” is a dead link by today while I remember them to run also detailed user analysis. Unfortunately, the next cloud news aggregator is buggy after all these years with updates occuring only sporadically. I therefore moved to Miniflux that works right out of the box. The only thing I wanted to change in templates/item.php is the following line from

<a href="<?= $item['enclosure'] ?>" class="image-enclosure" rel="noreferrer" target="_blank"><?= t('attachment') ?></a>

to display the thumbnails

<img src="<?= $item['enclosure'] ?>" class="image-enclosure" rel="noreferrer" target="_blank"><?= t('') ?>

But even that’ si not possible as there is an excellent stand-alone news reader with Readkit on OS X.

Altmetric Spam and Twitter Bots

I can’t get rid of Altmetric Spam Emails while I see this company now also appearing on journal websites from Wiley and Taylor & Francis.
screen1

The only thing Altmetric is reporting here, is an activity of a Twitter Bot. Maybe it is their own bot?

As our attention span is so limited, Wiley and Taylor & Francis journals should avoid spamming the scientific community. Greetings to London whoever you are.

Not so big data

Lesenswert https://www.dasmagazin.ch/2016/12/03/ich-habe-nur-gezeigt-dass-es-die-bombe-gibt/

Zwei Psychologen war in den 1980ern der Nachweis gelungen, dass jeder Charakterzug eines Menschen sich anhand von fünf Persönlichkeitsdimensionen messen lässt, den Big Five: Offenheit (Wie aufgeschlossen sind Sie gegenüber Neuem?), Gewissenhaftigkeit (Wie perfektionistisch sind Sie?), Extraversion (Wie gesellig sind Sie?), Verträglichkeit (Wie rücksichtsvoll und kooperativ sind Sie?) und Neurotizismus (Sind Sie leicht verletzlich?).
… Bald kann sein Modell anhand von zehn Facebooks-Likes eine Person besser einschätzen als ein durchschnittlicher Arbeitskollege. 70 Likes reichen, um die Menschenkenntnis eines Freundes zu überbieten, 150 um die der Eltern, mit 300 Likes kann die Maschine das Verhalten einer Person eindeutiger vorhersagen als deren Partner.

Wissenschaft in der Filterblase?

Zuerstmal Entwarnung: die “Filterblase” ist keine Erfindung von Facebook, Zitat der SZ

Jeden Tag fällt Facebook also Urteile und bringt Menschen in der öffentlichen Debatte zum Schweigen. Für das eigentliche Sperren und Löschen hat Facebook Arvato, ein Subunternehmen von Bertelsmann, engagiert … Wäre Facebook ein Staat, wäre es eine Diktatur.

Trotzdem Entwarnung,  die Filterblase ist ein Mythos denn entscheidend ist mehr der Bekanntenkreis. Nach einem Science Artikel bekommt man ca acht Prozent weniger Inhalte von der anderen politischen Seite angezeigt, was eigentlich vernachlässigbar ist. Continue reading Wissenschaft in der Filterblase?

Mitarbeiter des Monats

Vor kurzem fiel mir ein Artikel in die Hand, bei dem ich wissen wollte was für ein Autor so etwas schreibt. Wurmerkrankungen als “old friends” zu bezeichnen, ist dumm und zynisch dazu, auch wenn es Tradition hat. Sorry an Frau I. S., “Forscherin des Monats” an einer Medizinischen Fakultät.

Die Wirtschaftswoche erklärt was es bedeutet, wenn Firmen ein

Foto in der Hall of Fame zwischen Kantine und Herrenklo an die Wand hängen. So kürt beispielsweise die Fastfood-Kette McDonald’s den Mitarbeiter des Monats oder der Autobauer Daimler den Verbesserungsvorschlag des Monats … Das sind die Möhren, die man dort dem Esel Angestellten vor die Nase hält, damit er schneller läuft.

Rat race

While working on a review about vitamin D and the microbiome, I came across an interesting article Immune-Microbiota Interactions: Dysbiosis as a Global Health Issue

Recent research, however, demonstrated that a number of specific interventions can lead to (partial) primary prevention of allergy, especially of atopic dermatitis (AD) and food allergy (FA). Three types of primary prevention strategies have been successfully studied: early administration of bacterial products (most studies are on probiotics), early moisturizing in infants at risk for AD and early exposure to allergenic foods (peanut and egg).

I am not so much convinced of any successful probiotics research that prevents all kind of allergy (ref, ref, just to name two). The interesting point, however, is the new recommendation to early exposure of allergenic foods. Does earlier exposure mean less exposure under vitamin D suppression that shouldn’t start before week 6?

Ciguatera

I will have a paper in the next issue of the  MMW describing a case report of Ciguatera in Cienfuegos / Cuba. Seems to be a common phenomenon there but unfortunately there is nothing in the Cuba guide books so far.
The pathology is extremely interesting  – sodium channel activation by P-CTX. I only wonder why there are no therapeutic attempts with long-lasting class Ia aNa channel blockers  Chinidin, Procainamid, Ajmalin, Disopyramid, Propafenon, Prajmalin. Or valproate for CNS activity.

Imagick library for R

When working for an exhibition in 2017, I found a new R library that allows nearly every image modification you could think of.

install.packages("magick")
library(magick)
magick_config()

gives you

image_read(path, density = NULL, depth = NULL)
image_write(image, path = NULL, format = NULL, quality = NULL, flatten = FALSE)
image_display(image, animate = TRUE)
image_browse(image, browser = getOption("browser"))
image_append(image, stack = FALSE)
image_average(image)
image_coalesce(image)
image_flatten(image, operator = NULL)
image_fft(image)
image_map(image, map, dither = FALSE)
image_montage(image)
image_morph(image, frames)
image_mosaic(image, operator = NULL)
image_join(...)
image_info(image)
image_animate(image, fps = 10, loop = 0, dispose = c("background","previous", "none"))

“Doodle” calendars on mobile devices

It’s always difficult if you can’t see all calendar entries on the road. So I am setting up new dates at wjst.de/dudel, cut + paste the subscription link to the Nextcloud/Owncloud calendar web frontend.

“Doodle” dates will then magically appear on all other devices.

Window of Opportunity

I very much liked the “Window of Opportunity” in the Nestle Nutrition Workshop Series 61, published by Karger in 2008. Page 180 has an interesting account of the hygiene hypothesis:

Dr. Bier: … The other is the issue of the hygiene hypothesis, the cleaner environment. We are just in a somewhat less dirty environment, we are not in a clean environment, and that is the problem I have with that particular approach.

So, I am not alone

Dr. Barker:… I am guilty of inventing the term “hygiene hypothesis” as an explanation of the epidemic of appendicitis that followed the introduction of running hot water into housing of Western countries.

According to Sozanska et al. the hygiene hypothesis has more fathers

In 1970, Peter Preston1 posed the following question: ‘‘Is the atopic syndrome a consequence of good hygiene?’’ If this was the case, he argued that ‘‘the manifestations of atopy . would have appeared in given areas only after standards of hygiene . had been raised to high levels.‘‘

while David Strachan calls  it a misnomer since I know him. The last occasion was in the BMJ in August 2014

As the authors correctly point out, the term “hygiene hypothesis”, which is often attributed to my BMJ 1989 paper, is actually shorthand for a line of argument established much earlier. When presenting my own work, I regularly remind my audience that the ideas presented in the BMJ 1989 paper were inspired by David Barker’s publications on acute appendicitis a year or two before. However, as the authors acknowledge, Barker’s “hygiene hypothesis for appendicitis” was in turn influenced by earlier thinking.
I also recount that the inclusion of “hygiene” in the title of my paper (along with “hay fever” and “household size”) owed more to an alliterative tendency than to my aspiration to claim a new scientific paradigm. What interested me over the subsequent years was how, after initial disdain on grounds of implausibility, the immunological community enthusiastically endorsed the concept of the “hygiene hypothesis” as soon as they had proposed a cellular mechanism to explain it!
[…]
Indeed, the frustration over 25 years of epidemiological and immunological investigation is that so little progress has been made in identifying the biologically relevant exposures which “explain” the frequently replicated epidemiological observations linking allergic sensitisation and atopic disease (inversely) to family size and to “unhygienic” environments such as farming, separately and in combination…
