Dr. Rainer Wanke is a physicist working in the field of experimental particle physics at the University of Mainz, Germany. He is working on the NA62 experiment at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, which measures ultra-rare K-meson decays. This involves both, particle detector development and the analysis of data taken with those particle detectors. He furthermore teaches statistics for undergraduate students in Mainz.

A Commentary on “Most People are not WEIRD” by Joseph Henrich et al., Nature (2010)

Prof. Joseph Henrich is an anthropologist at the Department of Human Evolutionary Biology at Harvard University, Cambridge, USA. His focus is on evolutionary approaches to psychology, decision-making and culture. Together with his colleagues Stephen J. Heine and Ara Norenzayan at the University of British Columbia, Vancouver, CA, he was the first to point out that, in economics, psychology and cognitive science, conclusions are generally drawn from study participants with the same background: Western, Educated, Industrialized, Rich and Democratic (WEIRD). In addition, primarily students form the majority of test subjects. Still, researchers – often unintentionally – claim that their findings apply to everybody.

Open access sharing contributes nowadays a major part to the publication process in many different scientific disciplines. One could think it is an invention of modern time, however, the idea to make data and literature widely available is quite old: Libraries.

Dear Reader,

Even though I was a member of this editorial board for almost five years, I never wrote the editorial of an issue. Since I finished my university education and will soon start my industrial career, forcing me to leave JUnQ, it is my pleasure to write it for the current issue.

The feature topic this time deals with a problem, which has been in the press a lot lately: Misuse of Statistics.

Dear Readers,

We are delighted to bring to you the 12th issue of JUnQ. This time round, the central theme deals with Statistics in Science and what it entails and how can it be misused. We held insightful interviews with few of the best experts in Statistics and we present their views about the current era where mis-interpretations of data abound. It is heartening to see that the publication of negative or null results still is important for many in science. We have an article on Pretreatment of Steel and Zinc surfaces that highlights such details. Also in the days ahead, open access will be the norm and we present an excellent commentary on it.

We hope you feel excited about our newest issue of JUnQ!

— Soham Roy on behalf of the editorial board

The formation of a conversion layer for corrosion protection based on phytic acid (PA) solutions is described several times in the literature. The promising results induced us to verify the performance of PA based conversion layers as pre-treatment for organic coatings. The spectroscopic and optical analysis with infrared spectroscopy, atomic force microscopy, and scanning electron microscopy of the generated layer strengthened the hypothesis of a corrosion protective layer. Furthermore, the electrochemical analysis with cyclic voltammetry supported it but the results of the electrochemical impedance spectroscopy provided a first hint of an instable layer. Unfortunately, all kinds of tested conversion layers based on PA with and without a combination with molybdate increased the delamination of an applied coating and accelerated the corrosion process in the salt spray test. Therefore, all investigated PA based conversion layers are not suitable as pre-treatments for organic coatings.

Klaus Roth is an emeritus professor at the Freie Universitaet Berlin. He studied chemistry at the Freie Universitaet Berlin from 1964 – 1969 and completed his dissertation at the same university in 1973. After a post-doctoral stay at the Institute for Medical Research in Mill Hill, London from 1979 – 1980, he completed his habilitation at the Freie Universitaet Berlin in 1981. Between 1986 – 1988, he held a position as visiting professor at the University of California in San Francisco, after which he returned to his home university as extraordinary professor and became full professor in 2000. During his research career, he dealt with many aspects of NMR spectroscopy and also popular science such as the chemistry behind licorice sweets, balloons, and la fee verte. Furthermore, he is interested in the Ig Nobel Prize, a scientific award similar to the “regular” Nobel Prize but somewhat more peculiar. In this interview, he gives an insight into this alternative award.

Today, we find modern technologies everywhere in our daily life: computers, smart phones, navigation systems, wearables, high-tech medicine. Usually, they did not come by chance. These technologies are a result of fundamental research and breakthroughs and were developed by scientists, engineers and clever inventors.

When relating light to biology, the first thing that pops into one’s mind is photosynthesis. The sunlight shines onto the leaves, photons excite the light-sensitive molecule chlorophyll and with the use of several cascades, nature produces carbohydrates and oxygen out of carbon dioxide and water. The usage of light is the fundament of eukaryotic life on earth and there is only little life that can exist without it.

The Leibniz Association was founded in 1995 after a fusion of institutions of the Western German association “Blaue Liste” and other research institutions of the former German Democratic Republic (GDR). It was named after the German polymath Gottfried Wilhelm Leibniz (1646 – 1716). The association is particularly known in the eastern parts of Germany, being the biggest research association there. Interestingly, the Leibniz Association even patronizes several museums and the most commonly known are the Senckenberg institution in Frankfurt a. M. and Deutsches Museum in Munich. We spoke with Christoph Herbort-von Loeper who is deputy press officer of the Leibniz Association.
