Shaking Hands, like rubbing noses or kissing cheeks are social practices you will have to master depending on which society you live in. After the Covid-19 crisis we have become more careful to shake hands or exchanges of touching another person. The handshake has another medical function as well. If we are approaching eachother to shake hands, we prepare our handgrip mentally and physically.
It is exactly the strength of the handgrip, which serves as measure of another person’s health. Believe it or not, your handgrip is telling a lot about your general muscle strength. Of course, it is possible to conceal the true strength, but most people seem to have an intuitive handgrip with less mentally controlled strength of application. Medical studies mostly confirm the correlation of handgrip strength and frailty in older persons, predominantly for women. The conclusions of these studies lead us to a preventive approach of exercising your hand grip strength and other muscles in order to reduce frailty and to increase even life expectancy. After Covid-19 we should return to shaking hands more forcefully than ever before. Exercising by shaking hands with yourself or shaking your foot with your hand as alternative are fun exercises. The scientifically confounding effect of laughing while exercising might additionally cheer you up. Balance and joy are additional features of a healthy longevity.

Special
We all value special skills and specialists. In Berlin is a whole week devoted to the special event of the #SOWG. These are the special Olympics world games. Berlin is booming with special people all around. Already the arrivals of the athletes to Berlin tests the public transport system as much as private infrastructure to welcome persons with special needs. Rather than the waste that is produced for normal Olympic games the same incredible amounts of money should be devoted to make cities more welcoming to special people every day. We have become as societies so used to speed up things as much as we can that we have forgotten the value of allowing people to live their lives with their own speed and rhythm. Looking at the huge numbers of private sponsors for the SOWG it becomes obvious that many people care to support these special people on their journey. I am more willing to pay taxes for such efforts than the public money wasted for football, like TV-rights or stadium buildings. The joint experience of love and joy with these extraordinary persons makes us all happy and rich. Happiness is the new “wealth of nations”. Inclusion brings happiness to more than just the normal. We wish you all a happy #SOWG. The 
stars are you.
Air pollution
Only if we measure air pollution , we shall be able to be sure it is not getting worse or is improving. The European Environment Agency has developed an app that gives us fairly accurate measure of several important indicators of air pollution or air quality as they prefer to name the indicators. With the wild fires in Canada and the repercussions of this in U.S. cities we are certainly aware that air pollution by neighbours is just as important to know as air polllution originating in your own country.
In Europe this matters as well. Therefore the comparative view on air pollution is a necessary precondition to coordinate action within the EU. Specific meteological conditions yield SMOG in winter and too much heat facilitates SMOG in summer. Thousands of people die every year due to effects of air pollution. This is all well-known and documented.
In Science Advances (2023-6-9) new evidence is presented that fine particles (PM 2.5) in air transport influenza H1N1 viruses into the lower respiratory system and even other more distant organs like liver and kidneys. The conclusion is easy: Reduce air pollution much further, this saves lives and lots of costs in the health system as well. Well-being is advanced sometimes by doing less rather than more. Working more in the home office than in the inner city might reduce the peak of an influenza wave. New solutions to old problems are feasible with new technological advances and implementation like fibre-optic cables for fast internet service also in remote areas. Using the “Science Advances” should allow us to rethink our production and consumption model for the improvement of living and working conditions for all. Many extensions of our economic model shall be based on the “beyond growth” logic. We just need to dare to think and implement policies accordingly, rather than to continue to do the same mistakes over and over again.

Avers
Der kurze Titel „Avers“ der Sammlung von Novellen des Autors J.M.G.Le Clézio lässt keine Wundergeschichten erwarten. Der kleingedruckte Untertitel „Des nouvelles des indésiables“ noch weniger. Dennoch, aus der Sammlung von Kurzgeschichten werden die kleinen Heldinnen und Helden des Überlebens in unserer komplexen Welt vorgestellt. Mal mit, oft ohne „Happy End“ werden Kinderschicksale erzählt, die uns nachhaltig berühren. Schule ist für die kleinen Helden ein Fremdwort. Der tägliche Überlebenskampf für Nahrung, Gefahr von Kinderarbeit, einfach in Ruhe gelassen werden oder dem Krieg zu entkommen, steht im Vordergrund. Fluchtwege wäre für mich ein möglicher Titel einer deutschen Übersetzung. Flucht vor Missbrauch und die Brutalität des Alltags in Kriegsgebieten sollten uns sensibilisieren für „la Misère du Monde“.
Die unerwünschten Novellen von Le Clézio kommen auf leisen Sohlen oder eher barfuß daher. Sie lassen uns die ständige Herausforderung der Humanität spüren. Menschen, Kindern, Menschenwürde ermöglichen, ist nach wie vor eine riesige Aufgabe. Der Ansatz an konkreten Schicksalen aufzuzeigen, wie wenig es oft braucht, damit Kinder eine faire Chance bekommen, muss uns aufhorchen lassen. Obdachlose werden bei Le Clézio zu „fantômes dans la rue“. Wir ignorieren ihre Präsenz allzu gerne.
Nach 60 Jahren Heinrich Böll „Ansichten eines Clowns“ rütteln uns die Novellen von Le Clézio wieder wach. Wirkliche Humanität braucht uns alle und das ständig, nicht nur sonntags. Aversionen ablegen und sich dem Unerwünschten zuwenden, das fordert den ganzen Menschen. Überforderung gilt nicht als Gegenargument. Wir sind viele, helfen wir. (Image: Extrait, Atelier Albrecht Dürer um 1500).
Ground Water
The European Environment Agency collects annual data on pesticides in the ground water. The water most of us use in some form or drink. This used to be possible without too much thinking a generation or two ago. We now learn that this might be more and more dangerous, particularly in areas, where less rainfall and prolonged periods of draughts most likely increase concentrations of pesticides even in our tap water. Drinking this, raises more concerns. We know that in big cities and nearby of hospitals water quality is worse due to the concentration of particles from chemicals applied to increase contrasts in medical imaging. Pesticides are mainly used in agriculture, road and rail maintenance, but also households apply them for simplicity.
Snails (escargots) might invade your garden and even your home at times. However, it is just a little bit of exercise to “relocate” them in a decent place other than your home. Prepare a race for several ones and bet on who is going to win, but please refrain from the use of more pesticides. Several species of them are consumed and, depending on your taste, considered a delicious part of a meal (for example in Bourgogne, France). It should be easy to agree to stop the heavy use of pesticides across Europe and beyond. We shall have to protect the salads we grow differently. Human intelligence is able to allow other solutions than just killing as efficiently as possible ,at the same time, endangering our own species. (Comparable data EEA below). 
See Wasser
Der Bericht der europäischen Umweltagentur 2023 beschreibt eine durchschnittlich gute Wasserqualität der Seen in der EU (Link). Die Aufmerksamkeit für das Baden in den Seen und als touristisch wertvolle Naherholungsgebiete haben die Beachtung in den letzten Jahren wieder steigen lassen. Das ging leider oft auf Kosten der zu Wasserstraßen ausgebauten fließenden Gewässern. Dort befanden sich bis vor einigen Jahren noch vielerorts Flussbäder. Das war früher riskant und ist heute eigentlich größtenteils verboten. Wieder etwas, das wir dem Wirtschaftswachstum geopfert haben. Mehr Wirtschaftswachstum erscheint statistisch sinnvoll, mehr Lebensqualität hat das aber nicht immer mitsichgebracht. 
Waldbrände
Waldbrände sind leider jenseits vom Süden Europas auch im Zentrum von Europa ein Bestandteil der täglichen Gefahren geworden. Vor 50 Jahren waren die seltenen heißen Sommer die große Gefahr. Seit einiger Zeit bemerken wir öfter heiße Sommerwochen, die die Wälder austrocknen und leicht entzündlich machen. Jetzt haben wir die noch frühere Sommersaison nicht nur im Süden, sondern auch im mittleren Europa. Neben den Bränden in der Lausitz in Deutschland, kämpfen Feuerwehrleute öfter in den französischen nördlicheren Waldregionen mit Bränden. Eine Nachricht, wie die zum Brand Anfang Juni im „Forêt Fontainebleau“, sollte uns klar machen, da brennt unserer europäisches ökologisches und kulturelles Erbe. Jeder hat die brennende Kathedrale „Notre Dame de Paris“ noch in Erinnerung. Da war Klimawandel nicht die Ursache. Bei den Waldbränden sieht das anders aus. Das Ergebnis ist das gleiche. Die Vernichtung unseres kulturellen Erbes schreitet voran ohne Prävention. Das ist eine zentrale Aufgabe. Nicht erst in der Zukunft. Prävention verlangt Handeln, Planen und Implementieren schon heute. Das ist ein riesiges Qualifizierungsprogramm nötig. Es umfasst die Sensibilisierung für die allgegenwärtigen Gefahren genauso, wie das Schulen allfälliger Einsätze von professionellen und freiwilligen Helfenden. Gefahr erkannt, heißt leider nicht schon Gefahr gebannt. Da gibt es viele Zwischenschritte, die geprobt sein wollen, damit ein effektiver Einsatz gelingen kann. Es bleibt viel zu tun, packen wir’s endlich an. (Artikel in La Marne 7.6.2023 S.6) 
Corruption EP
Corruption is a severe crime. Not only in administrations, organisations and enterprises, but primarily in democracies it is discrediting political systems. Autocracies rely on corruption as a major tool to be able to persist over time. They are used to such practices. Democracies rely on meritocratic systems, where ideas, effort and winning elections should be the major ingredient of achieving higher positions in organisations, enterprises, political parties and democracies. This is not easy to ensure. The European parliament has a tough time to get rid of an enemy of the democratic Europe. Rather than stepping aside for the time of the legal procedure, Eva Kaili, accused, but not yet convicted of corruption is willing to destroy the European project as much as she can. If money can buy political decisions, the European project will no longer find wide-spread support. Big interests will always have a strategic advantage, however, the ethical principles on which democracies are found have to guard against corrupt misbehaviour. The same applies to the business world. Even low corruption countries like Sweden still face a risk of adverse effects of corruption like the negative impact on entrepreneurship on the local level. It is another context, but the same conclusion.
Additionally, it is part of the strategy of corrupt persons to portray themselves as victims of other persons’ wrong-doing. The major function of this strategy is to remind other persons in the corrupt network that the network has still some clout on its members as well as outside the inner circle. Hey, we are still alive and in powerful positions, they proclaim.
Therefore, the fight against corruption is a long and persistent one. Reducing the guards against early onsets usually is very lengthy to fight later on. Always a painful lesson for believers in democracy and the European project. (image Jacques Jordaens before 1678 “The King Drinks! Musées royaux des beaux arts, Brussels). 
Eyes
So-called deep learning algorithms can assist us in lots of routine tasks. Their applications seem to be spreading more rapidly than we commonly believe. The recent paper published in “Lancet Digit Health 2023; 5: e257–64” shows the relevance for medical screening again. Beyond skin or breast cancer, digital images have for years or decades been subject to studies using deep learning algorithms to early detection of cancer and other diseases. Now Google has published an additional potential application of algorithmic learning that assists in diagnosing blood sugar levels among others. For diabetes scanning photographs of the external eye with professional equipment (Zeiss Cirrus Photo 600) was used in the study, but the outlook hints already at the potential for most recent smartphone cameras to also be able to capture images of even better resolutions.
Just like measuring our weight and muscles as a weekly routine on scales, we shall have a more scientific look at our selfies soon. Spotting early onsets of several diseases will become a normal feature.
Early adopters of the new technology and screening potential of the smartphones might live even longer. Reminders to adopt or keep a healthy life style will be all around us. In some cultures, it is deeply offensive to look straight into the eyes of another person. We always knew that our eyes might tell a lot about us. Beyond mental health, they tell a lot about physical health, too.
Artists have always told us fascinating stories about eyes or how and what they see with their eyes. Scientists confirm that there is a lot of information in the eyes. (Image extract from MAD Paris, Picasso, Schiaparelli). 
Black White
Working at the Bibliothèque nationale de France (BnF.fr), just like visiting, allows you to benefit from the many temporary exhibitions based primarily on their own collections and donations to the BnF. For those who like “dessins, estampes, photographies”, there is a small exhibition as of June 2023 which features on these three techniques in the work of a single artist Edgar Degas from the impressionist movement. Walking through the exhibition or slowly scrolling the press documentation allows you to follow the artistic life course of Edgar Degas. He started with the pencil dessin and evolved to the printing of a single or sequences of “estampes” (up to 20) to impress us beyond black and white with multiples of 50 shades of grey. Degas seems like continuously searching for the uniqueness of the moment to present strong emotions or to summarise interpersonal relationships immersed in a specific spatial setting. Having demonstrated the richness of dessins and estampes as artistic, but a bit laborious technique, he devotes his last few years to a more intensive work taking photographs and proceeding to their development or tirage as printed versions. No matter which technique he applies, he has a special artistic view that allows to capture emotions and immortalise them. The painter’s eye, as well as later on in his artistic career the photographer’s eye, keep scrutinising himself in various forms of “auto-portraits”. Beyond youth, the pervasive obsession with selfies nowadays had its artistic precursor Edgar Degas for example. Whereas most photographers would classify a double exposure as a “raté”, Degas experimented with this almost like a cubist, Picasso-like techniques in photography. Actually, the last few images in the exhibition show the artistic reference Picasso made in his work to images, impressions and techniques that inspired him throughout his artistic work. There are amazing links in and across the history of art or arts. (BnF expo Edgar Degas 2023). 
Fröhlich
Fröhliche Wissenschaft. Das geht. Nach gut 6 Monaten mit einem Blogeintrag pro Tag hat sich eine Textsammlung ergeben, die recht umfassend ausgefallen ist. Nach eigenem Monitoring der Themen, wie die Bearbeitung der UN-Themen zu strategischen Entwicklungszielen, oder der alphabetischen Auflistung von Schlüsselwörtern der Sozialwissenschaften sind nahezu täglich Kommentare entstanden. Neu war für mich die Bildredaktion, als Kommentar, Erläuterung, Selbstkritik oder wissenschaftliche Referenz. Eine interessante Variante, Erkenntnisse mit Key-Visuals zu unterstützen. Die bildliche Erinnerung an Beiträge ist ein eigenes Inhaltsverzeichnis. Klar, Hund- und Katzenbilder werden das Ranking der am meisten aufgerufenen Beiträge gewinnen. Egal, wir machen fröhliche Wissenschaft, immer weiter, immer heiter, so bleibt es lebenslanges, lebensweites Lernen. 
2P2R
2 Pinot 2 Riesling. That could be the long version of 2P2R. However, this far from (politically) correct. The not-joking scientific medical journal “The Lancet” (Vol.401 Nr 10391) has next to the article on “Laughter is the best medicine” coping with trauma, the serious matter of how best to deal with pandemics. Remember 2P2R as the important lesson from the pandemic. Prevention, preparedness, response, and recovery (2P2R) are key. And don’t forget about primary health care or essential (medical and other) workers. This is, in short, the message from Arush Lal and Nina Schwalbe (Paper Link). Lots of social topics involved in this correspondence from the authors. Prevention is a big issue and, as in the health system, fighting continuously for sufficient resources. Prevention is in most cases less costly than curing a disease. Preparedness has direct costs. Masks and ventilators need to be produced, stored and monitored in their functionalities. Response has to be immediate, masks in China a important but do not allow us to respond fast to local emergencies. Recovery can be long and costly as well, just as we learn from Long-COVID patients.
Now we need to define properly what is included in primary health care. Medical doctors, nurses and technicians of hospitals have to reach patients and hospitals in pandemics or need child care, food etc. and, maybe, also laughter to avoid trauma. Remember 2P2R, but best in company with your loved ones, but not on your own. 
Himalaya
In May 2023 we commemorate the 70th anniversary of the first claiming of the Mount Everest in the Himalaya region of Nepal. Since then, the tourism to reach the highest mountain and have your photo taken there, has become a kind of over-tourism. Spectacular memories and images lead to persons taking unprecedented risks for a bit of fame. 30 persons have died on such expeditions. It is a bit more exclusive than running a marathon of 42,125 km, but even there occasional deaths are part of the race.
Nepal needs the foreign currency to build and rebuild the country. After resources have created the wealth of nations, it is tourist attractions that favour accumulation of wealth. Beware of over-exploiting nature in this respect. The consequences and costs are non-negligable. Climate change does not stop in front of tourist attractions. Some routes in mountains are already more dangerous due to melting of what we named wrongly permanently frozen areas (permafrost). Using virtual reality should allow us rapidly to experience the splendour of the highland Himalaya peaks and climbing. In the meantime enjoy some momo (Himalaya dish) rather than making preparations or training for the next top mountain. It is the images of the area that count, not us in front of the mountains or seemingly endless space. Images and photos taken can help us over the urge to visit this spectacular area ourselves. The planet will need us being satisfied this way, just like watching photos or movies rather than demanding to live in a splendid surrounding or building (castle). My home is my castle and my imagination is my travel book. 
Repair 3
Repair is our new mantra. Think of repairing in all domains as of now. Nature is showing us the way how to repair in many ways. Culture is also embracing the shift towards repairing as caring. If we really care about our planet, and there is no planet B, we shall have to repair in many more domains. We are used to repair bicycles, cars, roofs, windows etc. Repairing is never boring. You can improve the performance of a device or building by repairing it, even with relatively small budgets. Isolation of buildings is a good example of investing in upgrades through repairing. Rather than throwing away a functioning heating system repairing it with an energy saving device is enhancing its performance and produces fewer emissions in the short run. Heat pumps are the way forward for new installations. Shifting a sector, heating with gaz, to ensure longer lasting repair and improve options would save a lot of raw materials and CO2 as well. The construction sector has repair work almosts in its DNA, the energy sector will have to make that shift as well. Dare to repair. 
Krieg
„Zugunsten des Krieges kann man sagen: er macht den Sieger dumm, den Besiegten boshaft. Zugunsten des Krieges: er barbarisiert in beiden ebenfenannten Wirkungen und macht dadurch natürlicher; er ist für die Kultur Schlaf- oder Winterszeit, der Mensch kommt kräftiger zum Guten und Bösen aus ihm heraus.“ (Nietzsche, Menschliches, Allzumenschliches Nr. 444 S. 668).
Wir werden der Ukraine ermöglichen, ihre Kultur zu erhalten und gestärkt durch den Krieg zu bringen. Das können wir ermöglichen und gleichzeitig der von Putins Russland eingeleiteten Barbarisierung seiner eigenen Bevölkerung entgegen wirken. Nietzsche hatte das recht klar durchdacht und die Gefahren des Krieges kühl berechnet. In seinen aphoristischen Betrachtungen (u.a. Menschliches, Allzumenschliches) nachzulesen, lohnt immer mal wieder. Es schärft den Blick für zu schnell Vergessenes.
Die Einen dumm, die anderen boshaft gemacht. Es lässt sich damit nichts zugute des Krieges sagen, außer es werden Tendenzen, negative wie positive, verstärkt. Der Prozess der Zivilisation (Norbert Elias) wird auf barbarische Zeiten zurückgeworfen. Nur mit Erhalt und Förderung der Kultur kann dem begegnet werden. Die Ukraine ist auf einem vielschichtigem, demokratischem und kulturellem Weg in die Zukunft. 
Frau, Leben, Freiheit
Seit der brutalen Tötung einer Frau im Iran gehen viele Iranerinnen und Iraner auf die Straße. Als Zeichen ihres Protests rufen sie: Frau, Leben, Freiheit! Das ist und bleibt eine kurze Zusammenfassung für die Forderungen der Frauen, die trotz massiver Unterdrückung unablässig demonstrieren. Viele Hinrichtungen und Misshandlungen von Frauen werden wir weiter anprangern und fordern den internationalen Druck auf das Regime im Iran zu erhöhen. Wir dürfen nicht wegschauen, sondern werden weiterhin die Öffentlichkeit wachhalten. Diese aktiv für Menschenrechte eintretende Stellungnahme wurde von Yasmin Fahimi (DGB-Vorsitzende) eindrücklich auf dem EGB-Kongress vorgetragen. Mit überwältigender Mehrheit wurde diese Resolution vom Kongress befürwortet. Die italienischen Gewerkschaften stimmten gleich ein in den Ruf: Donna, Vita, Liberta!
Bravi! So rufen viele sonst eher in den Opernsälen. Hier passt es zu der Stimmung auf dem EGB-Kongress. Mit großer Einigkeit und ausgeprägter Solidarität wurde eindrücklich Stärke bewiesen, die auch über Europa hinweg Strahlkraft besitzt. Bravi! Kurzvideo EGB-Iran-Resolution Yasmin Fahimi und italienischer Support. EGB-Iran-Akklamation-IT. 
Democracy is key
The ETUC congress in Berlin 2023 prepares the working agenda for the next 4 years. A lot of support across political parties is voiced in favour of the important role the ETUC plays in coordinating the European Trade Union Movement. The democratic forum of all delegates works before and during the congress on a comprehensive list of essentials for the movement. It is much more than about wages, as most people might believe. Of course, minimum wages and fair wages are always high on the agenda. The strength of the 2023 Berlin congress for me consists in the widespread and loud call to intensify democratic structures and broaden participation of workers at all levels. The power of the unions to fight for democracy is dearly needed in all European nations with the threat from far-right populist movements. Strengthening workers is the best way to foster democracy. Throughout the congress several support facilities have been mentioned like the SURE instrument as a step into a European labour market policy.
Public services have also enjoyed more popular support, since essential services were the jobs that kept our countries running during the COVID crisis.
A just transition to a green economy in a democratic spirit means taking everybody with us on this journey. Fighting poverty, inequality is still high on the agenda and most people are convinced that democratic societies are highly sensitive to injustices caused by education systems, remuneration systems, retirement systems and tax systems. Even industrial policy, to guarantee our independence and values, is also linked to essential workers cooperation.
Weak social policies erode the trust in our societies to handle crises. The engagement of trade unions is felt far beyond Europe. Gilbert F Houngbo (ILO), hopes that due diligence is rapidly implemented in Europe, because it will benefit workers well beyond Europe across the world.
Union leaders were arrested in Belarus and in many other countries where they stand for democratic values. Trade Unionist from Europe have shown their own commitment to fight for democracy and mobilize to convince more people and youth to join the movement. “Donner l’envie de s’engager …” (LeMonde 26-5-2023 p.28) “Raise the urge to get involved” – that is the democratic challenge. 
Jahrestage
Jahrestage sind die Geburtstage von Organisationen oder zeitgeschichtlichen Dokumenten. Der 23. Mai ist so ein Jahrestag. Alle BundesbürgerInnen sollten an diesem Tag die Verkündung des Grundgesetzes im Jahre 1949 feiern. 75 Jahre sind das in 2024. Die Ostdeutschen hatten mit den Füßen abgestimmt, dem Geltungsbereich des Grundgesetzes beizutreten. Eine gesamtdeutsche Verfassung lässt noch auf sich warten. Provisorien halten oft ganz gut.
160 Jahre SPD, feiern wir etwas verhalten, ob der enttäuschenden Wahlergebnisse der heutigen Sozialdemokraten beispielsweise in Berlin (außer in Bremen Mai 2023). Der Allgemeine Deutsche Arbeiterverein (ADAV) von 1863 in Leipzig begründete die lange Tradition und der Kampf für Rechte der Arbeiter. Zu dem Jahrestag der Sozialdemokratie passt der am 23.5.2023 in Berlin stattfindende Kongress, gleichzeitig zur 50 Jahre-Feier des Europäischen Gewerkschafsbundes (EGB). Viele Sozialdemokraten haben dabei Anlass beides zu feiern. Ferdinand Lassalle, Gründer des ADAV, forderte aufgrund seiner These vom „ehernen Lohngesetz“, die Armutsbekämpfung zu einem Hauptthema zu machen. 160 Jahre später feiert der EGB in Berlin auf seinem 15. Kongress die erfolgreiche Arbeit für eine europäische Richtlinie für Mindestlöhne. Manche Sprünge brauchen sehr viel Anlauf.
Weiter hinten in der Warteschlange der Aufmerksamkeitsökonomie der Jahretage reiht sich der 25. Jahrestag der Europäischen Zentralbank am 24.5.2023 in Frankfurt ein. Auf allen Feiern gibt es einen persönlichen Vortrag des deutschen Bundeskanzlers Olaf Scholz (gerade zurück aus Hiroshima und Südkorea). Sein Ausrufen der „Zeitenwende“ (Artikel in Foreign Affairs) wird deutlich in dem tösenden Applaus für die Aufnahme der Ukrainischen Gewerkschaften in den EGB (Bild unten) auf dem EGB-Kongress, der quasi im Laufschritt von der DGB-Vorsitzenden Yasmin Fahimi eröffnet wurde. Jahrestage können wehmütige Blicke in die Vergangenheit sein. Dem EGB-Kongress ist ein zukunftsweisender Auftakt „à la Zeitenwende“ gelungen. 
Gentrification
We teach about the process of gentrification and segregation in sociology in most of our courses. Consulting is also busy with telling policy makers, urban planners and architects about this fundamental social process. A mathematical description of the process has been provided by Schelling as well. A recent striking depiction of the process evolving over years in Brussels is produced by Karim Douieb (dataViz and Jetpack, image below! and more, THANKS). The data is from the Brussels institute of statistics and analysis. Policy-makers have a hard time to work against the well-known tendency: birds of the same feather, gather together. Humans do not seem to be much different, at least when it comes to large metropolitan cities. Only a small China town is missing in Brussels.
What is masked in the grouping by nationalities of residents, is the underlying mechanisms that drive this gentrification. Even previously mixed parts of the city might suffer a slow process of erosion due to educational, job, wealth, poverty and housing differentiation between people and Brussels communities. Falling behind in educational achievement, then higher unemployment leads to lower credit worthiness and residence in less comfortable housing. The Belgian and EU15 residents are much more likely to follow virtuous upward mobility. Hence the process of gentrification trickles down through subsequent generations. Start with learning and socialising of kids and adult learning to overcome the discriminatory process. Ethnic communities will also have to open up to interact with locals. Social progress is hard work for all. 
Put People First
Put people first is a natural claim of human beings. We tend to abstract from the fact that we implicitly rely on a sufficient biodiversity for our survival. Therefore, the natural claim to put people first has many preconditions itself and severe implications. The most obvious implication is related to our world of production and consumption. We need to build an economy that serves its people rather than one that uses up human resources and discards people to an inferior rank of importance. Externalising health and safety at work to save money in the process of production will only cost society much more later on. This needs to be part of the balance sheet of companies not only “national accounts” or relegated to some health statistics hardly known to the public.
Put people first in consumption, has come to our attention recently. With energy prices rising due to Russia’s war on Ukraine territory we have learned that energy prices may be grossly distorted. Firms’ versus consumers’ energy consumption became a thorny issue. Even legislation, like in Germany, that put people’s energy consumption before companies’ consumption of energy became subject for debate.
Same issue with artificial intelligence. Let’s put people first here as well. Discriminating use of language or biased conclusions due to wrong data input to train AI is not acceptable as excuse. AI may serve humans in their work or leisure, improve production lines through error detection or early onset of disease, but it cannot replace the human verification of a just or otherwise justified human intervention. Humans are not perfect, never will be either. This is a tough rule to teach the algorithms that guide AI. Put people first has a strong interpersonal or solidarity element enshrined in it. This is what matters, now, in the medium term as well as the long run. 
Beyond growth
We have reached the bio-physical limits to economic growth much earlier than most people and experts expected. The “Beyond growth conference” at the European Parliament 15.-17.5.2023 is quite unanimous in this verdict of collective failure. Some advocate “degrowth” in various forms. Maybe the framing of how to address the vital topic of how to set objectives for a post-growth economy needs an even broader perspective. It is a global issue, but the industrial growth societies around the globe will have to work together to find and implement solutions. The worldwide conference COP-XY are hardly delivering on the issue. At best they satisfy the ego of political leaders to address important issues providing nice images from nice places in the world (Paris agreement) to advance their own political campaigns.
From an economist’s view rather than solving a very complex issue with uncertain outcome, it is more instructive to, for example, start to produce the same economic and social well-being by using much less natural resources above all climate-toxic elements (Carbon-dioxide CO2, Chlorofluorocarbons CFC, or methane). These are simple first steps with a rather immediate effect. After the recent crises we have learned to safe resources (heating) and reduce mobility, just continuing on this trajectory is feasible. Vastly excessive forms of consumption need to be capped through targeted taxes that allow redistribution or investment in reduction of pollution. It isn’t hard to do, or “It’s easy, if you try“, we might sing. 
Barbie
Jede einzelne Person hat Assoziationen mit dem Wort Barbie. Eingehen möchte ich jetzt nicht auf Klaus Barbie. Die Barbie war und ist als Puppe zu einer Kultfigur als Spielfigur mehrerer Generationen geworden. Dadurch hat die erfolgreiche Kommerzialisierung seit 1959 eine wirkmächtige Erfolgsgeschichte in den 60er und 70er Jahren erzielt. Zuletzt hat die kulturelle Öffnung hin zu „people of colour“, transgender und außergewöhnliche Charaktere den Gleichstellungsgedanken figürlich und spielerisch umgesetzt. Wenige Spielsachen erlauben eine solche Öffnung und Modernisierung über ihren „Lebensverlauf“. Die Barbie oder Der Barbie, wie auch immer, ermöglichen spielerisch Diversität zu erleben oder zu simulieren. So kann früh Stereotypen entgegengewirkt werden, wenn denn der Wille der Eltern oder Mitspielenden das ermöglichen wollen. Barbies sind schon längst ebenso zu Sammlerobjekten mutiert. Im Eingang zu IDENA (u.a. Spielwarengroßhändler) fand ich eine Würdigung dieses Bestsellers mit „Vintage Kleidern und Accessoires“ samt Hinweis auf Designer Entwürfe à la Karl Lagerfeld. Lernen sich zu kleiden, Stereotype erkennen und damit überwindend spielen können, das alles kann auch Barbie-spielen sein. Wo Sexismus nicht weit ist, kann aber Empowerment gewinnen. Und die Barbie hat Ken immer in die Tasche gesteckt. Das kann Hoffnung vermitteln. Die sogenannten sozialen Medien haben viel stärkere Stereotype geprägt und haben ihre Anhängenden viel fester im Griff als es eine Barbie je erreicht hat. Le Monde 2023-5-4 hat die Doku zur Geschichte der Barbie wohlwollend kommentiert. 
Biotop
Die Sensationspresse, zu der leider mehr und mehr ehemals seriöse Zeitungen neigen, zitiert Biotope meistens als Wirtschaftsbremse, Wachstumsverhinderung oder Spaßbremse. Da fällt es schwer dagegenzuhalten. Biodiversität ist nicht umsonst zu haben. Viele Schmetterlingsarten leben bestens angepasst an ihr ökologisches Umfeld, vergleichbar einem Biotop. Farbenpracht dient zur Tarnung im Gelände oder zum Anlocken von Paarungspartnern. Im Botanischen Garten in Berlin werden solche Inseln der Glückseligen für viele Regionen Europas und darüber hinaus nachgestellt. Der frühe Schmetterling von Ende April ist kaum zu bemerken, so gut passt seine Farbkonstellation in sein Umfeld. Es werden richtige Suchbilder und Geduldsproben, die Falter zu entdecken (bitte unten testen). Belohnung lockt für die Geduldigen, wenn das auch vielen von uns unerträglich schwerfällt. Zu schnell sind die Umgebungen für vermeintliche, kurzfristige, wirtschaftliche Interessen zerstört und die angepasste Tierwelt ebenso. Das Bundesnaturschutzgesetz (BNatSchG) intentiert einen Schutz. Der ist aber wohl allzu leicht auszuhebeln. So wird die Farbenpracht und das Tanzen der Schmetterlinge zunehmend in Konzertsälen zu hören oder darüber zu lesen sein, aber seltener in Biotopen zu bewundern sein. Artenvielfalt als Biodiversität braucht die passenden Räume dazu. Eine große Aufgabe bei dem weiteren Anwachsen unserer Spezies.
Hannover Messe
Es war wieder einmal Hannover Messe. Das jährliche Treffen der Industrie mit samt der neuesten und manchmal auch älteren technischen Lösungen bietet eine eindrückliche Plattform zur Repräsentation von technischen Problemlösungen (offizielle Bilder LINK) . Da gibt es Lösungen für Probleme, bei denen wir noch nicht einmal wussten, dass wir sie haben oder einmal haben werden. So überrascht es nicht dort einige Firmen gelistet zu sehen, die ihre Dienste und Produkte anpreisen für die Unterstützung mit künstlicher Intelligenz, aber eben auch das Erkennen von Mogelei unter Zuhilfenahme von künstlicher Intelligenz. Also so ähnlich wie auf einer Automesse gibt es auch eine Abteilung die Rettungs- und Krankenwagen präsentiert. Technische Lösungen denken, wenn sie gute Lösungen sind, eben immer gleich ihr eigenes Versagen mit. Es bleibt letztlich nur die Frage, wie viele Versagensschleifen mitgedacht worden sind oder mitgedacht werden können. Der menschliche Faktor (als Fehlerursache) ist dabei ein sehr schwer auszuschließender Problemfall. Das musste nun auch die Hannover Messe als Ganze erfahren. Wenn die Menschen, die die Menschen hin- und wieder wegbringen vom Messegelände streiken, dann kommt das nahezu einem GAU (größtem anzunehmendem Unfall) gleich. Es gibt nicht nur menschliches Versagen bei Maschinenabläufen zu berücksichtigen, sondern auch mangelnde Kooperationsbereitschaft oder gar Böswilligkeit. Dabei sind wir nun aber schon in der Science-fiction oder James Bond 007 gelandet. Artificial Intelligence wird nicht frei von diesen allzu menschlichen Schwächen sein. Ein paar Gedanken sollten wir als Interessenten einer Fortbestehung unserer Spezies schon haben. Zwischenzeitlich lasse ich ChatGPD mal die Frage beantworten, wie Angestellte der Deutschen Bahn effektiv ihre Forderungen durchsetzen können. Kein Wunder, dass autoritäre Länder bereits mit dem Regeln von künstilicher Intelligenz begonnen haben. Ich zumindest habe viel Energie und CO2 gespart, denn der Messebesuch in Hannover fand virtuell statt. Deswegen dann auch keine eigenen neuen Bilder. Zur Produktion von Fake-Images oder recycling-Bildern früherer Messen (Photoshoppen) fehlt mir die Lust, Zeit und wohl auch die künstlerische vielleicht sogar kriminelle Energie.
Photo Album
There have been many attempts to write a history of photography. Susan Sonntag’s account of photography and photographers remains the most successful one in my opinion. It includes a critical view on the medium just as much as capturing the power-related element of images and particularly photos. “Ouvrir l’album du monde” traces the history of photography from 1842-1911 starting with the invention by Louis Jacques Mandé Daguerre of the “daguerréotype” (Great press dossier Link to pdf-file). The attempt to “de-center” the history from the dominating western perspective is interesting as it reflects the spread and acquisition of the new technology by various “ruling groups” across the planet. Images like photos served and still serve often as proof (so easy to produce fakes and fake news nowadays). Proof of variety of existence of species, mankind, land acquisition and landscapes. Images of religious ideation, frequently forbidden, have been captured on photos. Many photos use up-front and profile perspectives on the same face, like police registry or the ethnographic documentations. This puts the visitor in an awkward position of “complice” to the process, judgement or documentation effort of a ruling more powerful class or colonial occupier. Historical embedding is necessary to balance the voyeurism of the camera. The film “Der vermessene Mensch”, reviewed in The New York Times recently, is a timely warning, how science and photography have served to create hierarchies of people, despite the fact, that “all men are created equal”. 
Repair 2
Ever since the visit to the exhibition “Care, Repair, Heal” at the Martin Gropiusbau in Berlin the image of flying protheses rests with me. Repairing the human body is feasible in many fantastic ways. The inner wounds, however, are less visible and sometimes hurting even more. In recognition of the thousands of victims again in the Russian war on Ukraine’s territory and the atrocities causes by mines to injure humans, we have to assist in caring, repairing and healing. This has not changed since the Great War or the Nazi-induced mass murder and mutilations. Humanity is unable to bann such landmines despite international conventions trying to achieve this.
The strong image produced by the protheses as clouds in the sky (Kadar Attia) remind us of the lasting effects of war. Images we had associated with the mutilated soldiers and civilians of the 2nd world war, many still around us in the 60s or 70s, are coming back to Europe. Writing about the 20th century, Aurélien Bellanger described in words a similar traumatising vision of flying protheses in his story of the lonely poet and philosopher. We cannot repair history, but we can work towards reducing useless additional suffering. It is part of the absurdities of our world that technology has created masterpieces to assist us and reduce suffering, but at the same time technology is applied to create the worst suffering as well. Rather than thinking of this relationship as 2 sides of the same coin, I prefer to hope for dialectic evolution towards a better synthesis solution using enforceable international law. Yes, I still have a dream! … 
On Noise
The 3 authors Daniel Kahneman, Olivier Sibony, Cass R. Sunstein have published in 2021 the impressive attempt to sell statistics to non-statisticians. The grip on the topic: “Noise. A Flaw in Human Judgment” is a bit misleading. Even the German translation (“Was unsere Entscheidungen verzerrt”), in my opinion, is grossly misleading. The work deals with judgment, or arriving at a sensible judgment. Decision-making is only the next step with a lot of other intervening processes. The German philosophical term since the enlightenment period has been “Urteilskraft“. We are all more or less familiar with the notion “bias” in judgment. Me, originating from the Moselle, will always be biased in favor of a Riesling compared to other vines. In addition to this naive bias I may apply a more professional judgment on wine. Testing several wines even from the same small area from the Moselle valley and then repeating the tasting I might make a noisy judgment. “When wine experts at a major US wine competition tasted the same wines twice, they scored only 18% of the wines identically (usually, the very worst ones).” (p. 80). In addition to the previously defined form of “level noise, pattern noise and system noise” (p.77), we have occasion noise, when judgments vary from an overall statistical perspective.
Having received a second dose of a vaccination yesterday and having spent an unpleasant night my judgment for this review might be biased, because of impatience. So in order to reduce bias and variants of noise I shall repeat the review at a later stage. Let’s see what this returns. But for today, the Epilogue “A less noisy world” (p.377) appears rather odd to me. It is probably an illusion to believe that we can create a less noisy world, even with the best of wishes. The authors abstract from any strategic use of noise to influence judgments. The political form of choosing judges for Constitutional Courts in the U.S. needs to be dealt with. Noise in judgments is an important element, but strategic use of bias might be more influential to impact outcomes. Noise, when faced with a judge who has a reputation to be very tough in sentences might be overturned in an appeal court decision. There are plenty of procedural ways to overcome noise in judgments. I agree with the authors that you better know about the noise in judgments than ignore it. Awareness of random errors and noise involved in grading exams and recruitment decisions have determined many excellent “failures” to leave historic contributions to our world. In music, maths or literature some splendid talents probably have been impeeded at earlier stages of their life to make average or normal careers. Some of them left us with fantastic pieces thanks to the noise in judgment of others.
There seems to be an age bias in the tolerance of noise in the acoustic sense. Noise in the statistical sense has left a strong mark on me when I learned about white noise as error or stochastic process.
