Children from a very early age onwards play strategic games. Even in the sandbox we can learn from surprising talents of how to get the shovel from the other player(s). Having grown up a bit the repertoire of strategies becomes a bit more sophisticated, but most children tend to apply the same ones now and then. For example, to obtain one of the always scarce places on the swing or the balance, you may reach your goal in attracting the occupant(s) to a supposed even more exciting object on the playground or outside of it. Once the occupants leave the swing to join you somewhere else, you rush back to the swing and hope that the other child(ren)/parents are not more powerful to take back the swing. Strategies on the playground are abundant. Most children run, or get run, through the full set of tricky strategies during their youth. If you still want to learn more, study economics (typical economist’s joke). Alternatively, if you like strategies claiming that other children are not following the rules or want to know how best to fix the rules so you’re going to win anyway, study law (lawyer’s jokes). If you believe fairness is your real best argument study sociology, philosophy or theology. Make sure most other people in the playground have a similar set of strategies otherwise fists and tears will be gaining the upper hand. 
Zoo Visit
The visit of a zoo is always a great event. Accordingly the prices of a visit have reached levels that are beyond prices for a cinema entry. Usually a whole day is spent with high emotions watching animals sleeping, walking or eating. Sometimes we can watch a training session or a brief medical intervention. Learning about the beauty of biodiversity is important because we treasure more what we like. Looking into the eyes of an animal stimulates affection. Gathering support for the preservation of ecosystems was and still is a great effort. And yet, we have to move beyond preservation to the restoration of ecosystems like in the UNDP projects (Link). Animal parks can contribute to this if we encourage such cooperation and co-financing. The awareness, understanding and willingness to engage in restoration projects is largely increased after the visit of a zoo. A second round effect is the potential to reduce international travel to destinations with rich animal diversity. Restoration is a win-win situation for wildlife habitat and our planet as a whole.
AI Sorting
Algorithms do the work behind AI systems. Therefore a basic understanding of how algorithms work is helpful to gauge the potential, risks and performance of such systems. The speed of computers determines the for example the amount of data you can sort at a reasonable time. Efficiency of the algorithm is an other factor. Here we go, we are already a bit absorbed into the the sorting as purely intellectual exercise. The website of Darryl Nester shows a playful programming exercise to sort numbers from 1 to 15 in a fast way (Link to play sorting). If you watch the sorting as it runs you realize that programs are much faster than us in such simple numeric tasks. Now think of applying this sorting routine or algorithm to a process of social sorting. The machine will sort social desirability scores of people’s behavior in the same simple fashion even for thousands of people. Whether proposed AI systems in human interaction or of human resource departments make use of such sorting algorithms we do not know. Sorting applicants is a computational task, but the data input of personal characteristics is derived from another more or less reliable source. Hence, the use of existing and newly available databases will create or eliminate bias. Watching sorting algorithms perform is an important learning experience to be able to critically assess what is likely to happen behind the curtains of AI.
Disappeared
We talk a lot in abstract terms of the loss of biodiversity. In the Museums of Natural History, like the one in Berlin, we can follow the trajectory of extinction of species. The dinosaurs are for most children the greatest attraction. No surprise, they are the biggest ones we have had on our planet. But there is a huge collection of disappeared species represented in the museums which we admire as a lost treasure or species threatened with extinction. Evolution had also created this rather big bird-like creature of the “dodo”. It couldn’t fly anymore and was inhabiting the splendid island of Mauritius. Hungry colonists passing have most likely literally eaten up this rather defenseless animal. Many other extinct species can be admired now only in museums and children feel naturally attached to some species that seem to have human expressions. Panda bears and gorillas rank high on such a list, but also some fish, especially if they smile or look at you straight into your eyes. This should help us take biodiversity and biodegradation more seriously. Children feel intuitively attracted to animals as natural companions. Something we have lost as adults and most of do not even realize this as a deficiency. The Nobel price winning author frm Mauritius has published a collection of short stories „Avers“ which captures the spirit of the island and the loss of species. J.M.G.Le Clézio seems to look at us through the eyes of children or a disappeared species. Magic moments are an escape as well as reason for hope.
Fertility BPS-SPB
Fertility is another example of the co-determination of the biological, psychological and societal spheres of life. The latest available data for Germany and Sweden in 2023 show a remarkable decline of 10% in the seasonally adjusted Total Fertility Rate (TFR) in both countries (Bujard, Andersson 2024). The TFR was at 1.3 in Germany and 1.5 in Sweden. This means both countries are well below their population replacement rate. In both countries the populations will shrink further. There are no easy answers to the question: why?
The co-determination of the biological, psychological and societal spheres of life seems to be combined driving force. The biological clocks are ticking for women who delayed birth. Maybe pollution of drinking water or PFAS, nanoparticles of plastics disturb fertility. Psychological reasons such as increased anxieties due to the Covid-19 pandemic, lock downs or closed schools have left parents without adequate support for 2 years. Isolation or loneliness could have delayed partnerships and fertility as a consequence. The social environment has also provided additional uncertainty as the cost of living has risen and affordable housing for families is scarce in both countries.
We have probably underestimated the effects of the “Zeitenwende” on people’s mind sets. Sweden has suddenly sought to join NATO to achieve a broader military safety net for its people. In Germany the experience of damages due to war or as a consequence of Russian occupied territory is very present in people’s mind. The war of Russia in Ukraine may have increased uncertainties, anxieties beyond the immediate effects of higher living costs, interest rates or prices for energy. At best fertility might only be delayed for some years, but the consequences of shrinking populations need to be taken seriously. Making societies more welcoming for children and their parents is part of the solution. 
AI and dialect
The training of Large Language Models (LLM) uses large data sets to learn about conventions of which words are combined with each other and which ones are less frequently employed in conjunction. Therefore, it does not really come as a surprise that training which uses standardised languages of American English might not be as valid for applications that receive input from minority languages or dialects. The study forthcoming in the field of Computer science and Language by Hofmann et al. (Link) provides evidence of the systematic bias against African American dialects in these models. Dialect prejudice remains a major concern in AI, just like in the day-to-day experiences of many people speaking a dialect. The study highlights that dialect speakers are more likely to be assigned less prestigious jobs if AI is used to sort applicants. Similarly, criminal sentences will harsher for speakers of African American. Even the more frequent attribution of death sentences for dialect speakers was evidenced.
If we translate this evidence to wide-spread applications of AI in the workplace, we realise that there are severe issues to resolve. The European Trade Union Congress (ETUC) has flagged the issue for some time (Link) and made recommendations of how to address these shortcomings. Human control and co-determination by employees are crucial in these applications to the world of work and employment. The need to justify decision-making concerning hiring and firing limit discrimination in the work place. This needs to be preserved in the 21st century collaborating with AI. The language barriers like dialects or multiple official languages in a country ask for a reconsideration of AI to avoid discrimination. Legal systems have to clarify the responsibilities of AI applications before too much harm has been caused.
There are huge potentials of AI as well in the preservation of dialects or interacting in a dialect. The cultural diversity may be preserved more easily, but discriminatory practices have to be eliminated from the basis of these models otherwise they become a severe legal risk for people, companies or public services who apply these large language models without careful scrutiny.

Sleeping BPS-SPB
Sleeping is a good example of the co-determination of the biological, psychological and societal spheres of life. The environment with the daily cycles of light and dark as well as the social norms of work and rest determine the circadian cycles of hormones. Shift work or otherwise disrupted sleep patterns depend on social norms like regulation of noise or light in cities. Healthy sleep patterns, therefore, depend to a large amount on regulation and implementation of those social norms. Birthday parties are tolerated, but much less the irregular partying in shared housing with lots of neighbours. Reducing social contacts during Covid-19 led to the changes in sleep patterns as well.
The psychological determinants of sleep go well beyond the world of dreams as theorized by Freud. Nowadays, we investigate all sorts of behavioural patterns that have an impact on sleeping like “bedtime technology use” of smartphones or the ability to switch off thinking of problems. Sleeping is a particular functional state of our mind. A lot of sorting of daily impressions into memory occurs during the different phases while sleeping. Persistent disrupted or impeded sleep is recognized as torture in severe cases. Stress at work or working overtime is also a major cause of sleep disorders.
The biological indicators used to investigate sleep have revealed a lot of links of sleep and the hormones of melatonin as well as cortisol. Testing has become more accessible and provides good indicators of how the biological clocks tick within our bodies.
However, we are only at the beginning of the analysis of more complex interactions of the multiple forms of interaction of the bio->psycho->social (BPS) as well as the social->psycho->bio (SPB) co-determination of sleeping. Scientific research is faced with a steep challenge as the direction of causality is not uniform except in very controlled experimental settings. Maybe the arts have coined and popularized a useful term in this respect. “I am in a New York state of mind”.

Sleep biology
Biological processes work hard during our sleep. Our immune system in particular benefits a great deal from undisturbed sleep. This is the simplest summary of the study by Kabrita et al. (2024).
We can study the temporal expression pattern of major histocompatibility complex MHC class I for example in mice. 2 groups of sleep-restricted versus normal mice reveal the biological impact of sleep restriction. In comparison to the control group sleep restriction in mice produced a bimodal pattern of Splenocytes with higher protein levels during the resting period. Such an increased protein expression during resting periods indicates a “preparedness for a potential infection”. Sleep recovery, even if short compared to the longer sleep restriction, allows to return to the baseline of protein levels. The good message is that at least mice seem to recover rather quickly from sleep deprivation with their immune response system.
The biology of repeated phases of longer sleep deprivation could inform us on the implications of sleep deprivation on aging processes. The biological responses in single event sleep deprivation seem to show a fast recovery pattern. Probably it is worth studying the same recovery process of groups of young versus aged mice.
Anecdotal evidence from myself indicates that recovery after sleep deprivation in older humans is no longer as fast as at younger ages. Behavioural responses might be less sleep deprivation (less fun) or longer recovery periods (stay in bed longer). The behavioural response of humans appears to be an obvious one. Instead of either or, we tend to go for both at the same time.

Korallenriff
Kinder verstehen direkt, dass es sich lohnt, Korallenriffe zu erhalten. Plastikmüll in den Meeren gefährdet die Korallenriffe und die bunte Vielfalt an Fischen, die darin leben. Ein kleines Theaterstück dazu von Kathrin Brunner begeistert Kinder, weil es sie erleben lässt, wie einfach Lösungen aussehen können. Den großen Leuten zeigen, wie traurig die Welt aussieht ohne die farbenfrohe Pracht der bunten Fische, wird sie schon zu Veränderungen bringen. Das Theaterstück und Buch dazu wurde am 16.3.2024 im FEZ in Berlin aufgeführt. Das Figurenspiel mit überleitendem Refrain, das vom Publikum gleichsam der Promenade in den „Bildern einer Ausstellung“ (Mussorgsky) mitgesungen haben, bildete jeweils eine gelungene emotionale Überleitung und Aufmerksamkeitspause. Wir wünschen uns noch viele kleine und große Besuchende für diese Aufführungen. Die Kinder werden es uns schon lehren, den blauen Planeten noch zu retten.
Family Music Days
Kids are queens, kings and princesses as well as princes at the family music days in Berlin at the FEZ. Kids can enjoy the full spectrum of musical experiences from just listening to playing themselves, if they feel like it or dare to risk a sound. Just making noise is okay, too. Building your very own version of a musical instrument is a great learning experience for the young. To make music it doesn’t always have to be an expensive instrument. Your own imagination assisted by persons with patience and passion creates marvelous sound experiences. Initiating kids to the endless worlds of sound is having lasting effects on them. Great to see a concert hall full of young enthusiasts. Learning is so much fun, if taught in accessible and inclusive ways. Professional instructors joined by many volunteers make the world go round for kids. Wish you we here. Let’s spread the message.
