In French cinema Jean Gabin is a much adored person. Equally, Marlene Dietrich had, probably an even more far reaching international career. Both were accomplished and successful actors long before the 2nd world war broke out. In the U.S both fell in love and had a long lasting romance together. Their war time activities and “engagement” in fighting Nazi-Germany were extraordinary. It meant that both took active roles to use their charisma to mobilize people and soldiers to fight for freedom.
Shortly after the war then, both made a last attempt to work together in a movie production, but it could not unite the couple again. The “Deutsche Kinemathek” displays currently a page from the Diary of the “Diva” to underscore to what extent “Dietrich” was depressed about the break-up of their longer lasting love affair. Some say Gabin was the only person who quit her, all (most?) other relationships were terminated by the Diva. The junctions of biographies are hard to predict. The circumstances of the 2nd world war and internalized civic obligations to fight for freedom and democracy were wholeheartedly shared by both, but eventually they grew apart nevertheless. Tough experiences even for the much adored persons on the forefront of the stages worldwide. There seem to be many instances of repetition of the same story not only in movies, but also in real life.

Image History
The archives of the history of movies and/or television show to us the multiple ways how images capture our attention and memories. Visual narratives are an own category of our personal and collective memory. The wide range of visual experiences are a powerful way to influence. Not only the movies and stories matter, but the whole range of images associated with the cinema world. Poster collections, newspapers and today the so-called social media multiply the original images. The Deutsche Kinemathek allows a special, critical understanding of image history as Germany has been using and abusing images and movies in a very manipulating manner historically. The message is: do not take images for face value. The ways and techniques to manipulate images have been widely used and are all around us today. Whereas the mass media in previous decades have dominated the collective memories we have entered into an era with many more subcultures that evolve within their own bubble of images. An original attempt to cut 65 movies of German film history into less than 4 minutes is presented in the exhibition (Milkowski and Simbeni). It focuses on gestures and “les regards”, “Blicke”, how the actresses and actors seem to look at us. Eyes capture attention, and this as soon as we open our eyes as children. Our brain works as image recorder and our memory algorithms tend to favor image recognition while processing images continuously. We do not know much about our own image sorting algorithm or algorithms yet. Research on aging of the brain gives some hints. With declining short term memory the images stored in long term memory take the upper hand. This makes an understanding of the history of images even more important.
Deutsche Kinemathek
Just in the vicinity of the Potsdamer Platz in Berlin you’ll find the Deutsche Kinemathek, the museum movies, actors, actresses, directors and the history of cinema in Germany. There is a small specialized library in the Kinemathek that allows to dive not only into journals and books, but also video material, scenarios and accessories. Of course, you will find a lot of material on all sorts of movie stars (heroines) over more than a hundred years. The “Divas” of the industry take up a large part of the exhibition. “Marlene Dietrich” much more than “Hildegard Knef“, the former born and the latter lived for a long time in Berlin-Schöneberg (Berlin-Pretty-Hill as some locals call it nowadays). The 2 Divas probably caused the funny translation. Anyway, the hall in the Kinemathek which is exclusively devoted to Marlene Dietrich impresses with a lot of glamour and mirrors around.
For those with not only a biographical, but also life course interest in cinema cherish the public access to the library. The most impressive table there is the desk with access to the Ukrainian movies and about cinema in Ukraine. A list with QR-codes allows you to readily approach the recent developments before and during the Russian aggression on Ukraine (See image below). After all Potsdamer Platz in Berlin was a hot-spot of the cold war period in the divided Berlin. A little bit of a “Metropolis-atmosphere” can still be felt. The Kinemathek explains well what this is all about. 
Time Perception
There are many different angles from which to look at time. Of course, we all do it several times a day or during boring meetings. The study by Ma, Cameron and Wiener (2024) highlights the bi-directional link of perceived time and memorability. Visual stimuli alter our perception of time. Watching a video we all make the experience that the perceived length of the time spent watching varies according to content and maybe only the cutting technique applied to shorten the perceived length. Similarly it has been demonstrated that looking for longer at an image and grasp the meaning or implicit story we tend to remember the image for longer. In courts it is a usual procedure to question the memory capacity of persons and the sources of bias. The study by Ma et al. demonstrates the impact of the size of the scene, how cluttered it is and aspects of memorability in visual perception. Our memories are co-determined by these factors. The other direction of causality i.e. that memorability determines the time perception seems equally at work. This apparent undetermined element, so far, calls for additional care when analyzing recall from memory. Memory is not only selective in terms of content, it also is subject to the impact of all sorts of visual stimuli.
Time can be many things. For humans it is everything but exact. In science we measure time with ever more exactitude and try to standardize time on the moon now. In addition to exact time, humans have perceived time and subjective versions and even concepts of time. About time to take time more seriously. 
Heroines
In youth we are open for a wide range of influences. Heroines in children’s literature, picture book or cartoons look back on a long history as successful influencers. Creation, transmission and criticism of stereotypes are all part of the scientific reflection on heroines and heros. Nowadays, influencers have taken over picture books through the use of more compelling videos.
In the 1950s,1960s and 1970s picture books or cartoons dominated the influences before mass media like television became more absorbing, addictive and powerful influencers. Children’s books are passed on from one generation to next generation. The French-speaking world (and beyond BBC reference) has witnessed the success of the illustrated booklets of the young “Caroline” (Hachette) and “Martine” (Casterman) exploring the world. Parents passed on their collection to children and had their own parents read the stories to their grand children.
Well, that’s how intergenerational transmission of cultural heritage has worked for a long time. It describes the basic social mechanism. Nevertheless, new forms of influencing emerged with new technologies. Successful illustrated narratives like “Caroline” and “Martine“ were adapted as television series as well. In France you could chose your side of either explorations with Caroline and her group of animals or the adventures of Martine.
Ideally it would be an occasion for the families and friends to discuss pros and cons of each character and, thereby, become aware of what is a stereotype, at least at a later stage of the life course. Gender stereotypes have evolved and to observe 2 boys colouring Martine images in public (Brussels book fair 2024, image below) was a positive surprise. It almost felt like a real world experience of the AI-enabled Barbie explorations. 
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. 
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.

Biographies
The biographies of painters, composers or artists in general can be reconstructed by use of their major works. The biography of René Magritte by Eric Rinckhout (2017) has chosen this way of a retrospective in images and explanatory texts. The biography is built around 50 major images starting with the first one by Magritte at the age of 28. “Les réveries du promeneur” (see below) deal with the confrontation of Magritte with death, suicide and the difficulty to find rational answers to all those questions of why this happens and what becomes of people who experience such a tragedy.
His own childhood was affected by such an event concerning his own mother who suffered from depression. Coping with the evolution of psychic illness over years and the absence of a supportive father have posed a steep challenge for the young person. Creation of art became a coping strategy as well as a relief for those who manage to eventually cross the bridge into their own life leaving behind the bad experiences. J.J. Rousseau was an influence on Magritte as well.
Finding your own destiny and your own style is a process. This process evolves over years. The chronological sequence of 50 images allows to follow the path taken. Thereby, it becomes possible to open up the personal learning and working trajectory of the artist. In retrospective perspective it seems often logical that one style or period of painting follows on from another one. However, in the forward living of the creative life many choices are heavily contingent on other circumstances. Influences of friends, exhibitions, reading, cinema, private or financial situations may determine the creative choices simultaneously or one at a time.
The chronological path of images writes a biography of a special kind. It allows to think in sequences just like in a sequence analysis as sociological methodology. Description, reconstruction, analysis, causality remain a challenge in our attempts to learn and understand more about biographies or the construction and reconstruction of life courses. 
Error 444
The error message 444 is a not so rare encounter while surfing on the web. The error code 444 stands for the message that from the side of the server the connection is closed without any additional message. The occurrence leaves you without further indication of what exactly went wrong in building a connection to a web service or website. You just simply get shut out and that’s it. It may be tough on you if concerns your online banking or other access to vital services delivered through the internet.
In organization science and social science there are many new studies dealing with the finding, dealing, coping or handling errors. It has become much more acceptable to deal openly with errors, blunders or failures. From an individual as well as organizational perspective the cultures that deal openly with these events seem to have a certain advantage to overcome the consequences of errors at all or faster than others.
In some biographies failures are part of the lessons learned throughout life. It is deemed important to acknowledge failures or paths not taken for better or worse. Organizations just like individuals seem to learn more intensively from their failures or omissions than from everything seemingly running smoothly. Learning curves are faster also for “machine learning” if you have access to a huge data set which contains ample data on failures rather than encountering failures after release. Hence, the compilation of errors is an important part or early stage of a learning process. Failed today? Fail again tomorrow. You’ll be really strong the days after although it might hurt. 
Force of dependency
Drugs have their particular strength in creating dependency. This is well known for tobacco or alcohol. Helping people to overcome the forces of dependency has its merits. At the same time it is big business. Vaping instead of smoking might be a way out one dependence but into another one. In the end it is an empirical question how many persons can escape the force of dependency of both types. Important to test the probability to get rid of the dependency altogether. With respect to hard, life-threatening drugs like Nitazene the death toll keeps rising in the UK. In the latter case changing the dependency is already a success. The sustainable deflection from drug dependency has to address underlying issues and health hazards. It is a rather individual issue. Society wide evaluation studies need to inform the debate also about placebo effects. The force of dependency might not only be physiological but psychological or linked to the social environment. All these potential effects have to be carefully sorted out before simple pseudo-solutions are implemented. Even the price and availability of drugs is part of the overall equation to solve the force of dependency.
