Digital Social Networks

Social networks have become the place to be. The need to distinguish the digital social networks from the social networks of people in the analog or “real” world is important, as we realize that many young persons seem to suffer from loneliness despite a hundred personal links in the digital social networks. This paradox of digital and non-digital social networks needs careful attention of researchers because of the opportunities and risks involved in the transferability of contacts from one network to another.
There is s a kind of “conversion rate” of digital contacts into face-to-face contacts and even purchases for marketing purposes in the world of business. The sociology of the virtual has to deal with these paradoxical social relationships and study the increasing phenomenon of being «alone together». Increasingly we are alone, but together. Over the life course this phenomenon and the digital social network paradox change as well.
To research such a topic we need rather intrusive, personal data and access to the digital traces of people as they construct and deconstruct either form of social networks.

Unexpected effects

It is, unfortunately, a rare event in science to publish unexpected effects of an experiment. Sometimes, results even turn out to be the opposite of what to tried to show with the use of an experimental setting. The learning for the science community, however, is bigger in such cases. Why? A carefully designed experiment (Oliveira et al. 2025) to measure the effects of 2 different 12 month long yoga trainings to prevent falls in 60+ persons (mean age 67) revealed that the less challenging “seated yoga” was better in preventing seniors from falls.
Participants in the more challenging Iyengar yoga-based sessions reported more falls in the 12 months follow-up period. Due to Covid-19 the trainings took place as an online course, which might have reduced the influence of a coach in correcting positions and observe other physiological or psychological issues with participants.
However, the insights are a great lesson for experiments to produce opposite results of expectations with the lesson that human beings can be rather complex. From a health psychology perspective, it might be the case that participants in the more challenging yoga classed became also more daring in balance as well as other exercises.
Just being overly confident compared to their positive improvements, which might turn around an initially positive effect on balance and falls. From a socio-economic perspective, we would question the implicit assumption of the study that participants have a random distribution or underlying tendency towards risky behaviour. The longer the observation window (post-intervention) is, the more intervening socio-economic factors enter into the physiological-behavioural equation. Hence, expect unexpected effects.

Inclusive images

In the last 2 decades we can observe a strong concern among photographers to broaden the spectrum covered by images beyond well established imagery of non-binary gender. Diversity in imagery has taken a broader scope to extend, for example, the age range of people who are portrayed as central topic of exhibitions. The topic of mental diversity is more recent and needs a similar or even increased sensitivity to do justice to the whole spectrum of people. The photography of people with mental challenges necessitates a much more careful approach to the persons and complex personalities the photographer intends to portray. Trust and the development of trust of more vulnerable persons is a time sensitive process. The work by Charlotte Abramow “Maurice, Tristesse et rigolade” is a fine example of a photographer who portrayed over a long time of taking care of her father, previously a medical doctor, The years of the final stages of the life course of her father have been the subject over many years as the survivor of an extended medical coma had to struggle with the tough challenge of re-learning basic life skills again.
Abramow portrays her father as an actor of his “second life”, where the borders between reality, reconfigurations of his memories,   and “mise en scene” to co-produce the images. The images go far beyond the portrayal of aging and mental challenges as a deficit of persons. Yes, it is an integral part of these persons, but there is so much fun and positive emotions that derive from the intensive collaboration of actor, father and photographer that the images stick with us for a longer time. The presentation of props along with the photos creates an immersive installation, which strengthens the emotional bonding with the inclusive images of the later phase of the life course of Maurice.

Marc Aurel Book 12

The closing book of Marc Aurel’s Meditations is taking issue with his own posterity. As a guideline for others, he formulated the claim not to care so much more about the opinions of others, but to stand by own reasoning and trust in one’s own opinion. “I have ofetn wondered how it is that everyone loves himself more than anyone else, but rates his own judgement of himself below that of others. … So it is that we have more respect for what our neighbours will think of us than we have for ourselves.” (Paragraph 4, Penguin Classics).
Of course, in the age of “philosophy as discourse” (Habermas), we are used to criticism of books and their authors. For the emperor philosopher this was less obvious, albeit the Socratic tradition of exchanges between teachers and their scholars was a kind of precursor of 20th century philosophy.
His writings in ancient Greek, however, remained little known and debated until its first Latin publication. Ever since, it has been a prominent work on ethics and leadership. The exhibition in Trier featured the copy of Helmut Schmidt, as the long reach of stoic writings on virtues and leadership.

Marc Aurel Book 7

In paragraph 63 Marc Aurel refers to Plato as one of his sources: “No soul”, says Plato, “likes to be robbed of truth” ( and continues himself) “– and the same holds of justice, moderation, kindness, and all such virtues. Essential that you should keep this constantly in your mind: this will make you more gentle to all.” The remarkable reasoning is to transform the own generalized experience into a behavioural recommendation. It may be argued that Marc Aurel starts from a kind of Aristotelian empirical study of persons in different life domains to derive an empirical fact. Based on this he develops a more Plato inspired “idealistic picture of mankind”. He is very much preoccupied with the philosophical question, how is a good life for all possible. In a previous paragraph (55) he outlined his 3 guiding fundamentals: (1) “The main principles in a man’s constitution is the social; (2)… resistance to the promptings of the flesh, like impulses; (3) judgement unhurried and undeceived”.
With such a claim for a “rational constitution” of man, he puts himself into the footsteps of previous philosophers of the ancient Greek tradition and, therefore, his writing in Greek rather than Latin is also a homage to this philosophical heritage.

Marc Aurel Philosopher

2025-9 marks an additional landmark in the achievements of the late Marc Aurel. In the Roman built city of Trier, 3 museums offer exhibitions on the life, ideas and imperial governance style of Marc Aurel. Libraries and bookshops around the city portray a wealth of books and studies by and about Marc Aurel as well in many languages (image below 2025-9). The stoic author and practitioner has served as an example of a leadership style which became for many subsequent leaders a hard-to-achieve precedent. The writing style of Marc Aurel in short paragraphs and aphorisms proved highly accessible, although his readership swell only after a Latin translation of his Greek original appeared in the 16th century. The title “Meditations” in English, “Pensées pou moi-même” in French or “Selbstbetrachtungen” in German demonstrate the difficulty to get to grips with the author’s intention and objectives in writing down these reflections on life, ethics, humanity and good governance. Through the use of Greek rather than Latin he puts himself in the line of Greek philosophers rather than the succession of Roman emperors. As the numbers of bad leaders still outnumber the good governance style advocated by Marc Aurel, these exhibitions in the Simeonstift, the Landesmuseum and the Stadtbibliothek are a perfect opportunity to demonstrate that good governance is something that can be studied and learned even in the distant Roman history.

AI earnings effects

In the first few years of wider adoption of AI in an economy, there is the expectation that this might lead to substantial productivity gains for enterprises which use it as well as for employees who are early adopters of the relatively new technology. The study by the Stanford Digital Economy Lab by  Chen, Chandar and Brynjolfsson (2025) showed that so far there are no significant earnings effects for employees. Based on millions of recent payroll data from US companies productivity gains have not trickled through to the paycheck in terms of monthly salaries. Participation of staff in a company’s overall turnover or profit might change this as time evolves. For civil servants the adoption of AI might mean increases in cases dealt with as some tasks can be executes faster than before with the use of AI.
The evidence points to employment effects of AI rather than earnings effects so far. A hypothesis is yet unresolved: senior employees using AI might employ fewer junior workers at entry positions, if these “hallucinating” young professionals can be replaced by hallucinating AI. In science the hallucination has sometimes lead to disruptive new approaches and findings. It is a tough choice to pick the young entrants with high productivity potential and eventually high remuneration for this in terms of labor earnings.

AI employment effects

The first robust empirical evidence about employment effects of AI in the USA has been published by the Stanford Digital Economy Lab by  Chen, Chandar and Brynjolfsson (2025). A previous paper by Wang and Wang (2025) highlighted the comparative advantage of persons who use AI in their work compared to others and the authors coined the term “learning by using technology”.  The prediction of the model was that there might be job losses of more than 20% in the long run and half of this already in the first 5 years of the introduction of the technology. The Stanford economists have estimated with real world data these effects in the USA and find quite surprisingly that the negative employment effects of AI have the strongest impact on young labor market entrants with few years of labor market experience. Middle-aged and more senior employees seem to benefit from “tacit knowledge” about the work, which is more difficult to replace with AI, at least for the time being of the early days of AI. This evidence is based on recent payroll data from the largest payroll processing firm “ADP” in the USA which has firms overrepresented from the manufacturing and services industries as reported in another paper  (Firm size maybe another source of bias).  However, the effect that youth 22-25 years of age suffered the most calls into question the common belief that older workers are more likely to suffer the consequences as during in the rise of the digital economy around the year 2000.

Vacation or Workation

Vacation or Workation, that is the question. Remote work and outsourcing of work have  created the opportunity for more people to work from distant places. Logging into the firm’s or the administration’s secured intranet enabled to work from where you prefer to work rather than on the premises of the firm. After the technological shift to enable secure remote work, the acceptability of remote work is a societal issue. Whereas bosses worked or had to work while on travel for many decades, the same has become feasible due to reduced costs for many other employees as well. The Covid-19 pandemic has forced another shift in the need to accept and advance remote work as well. Taken together the option of a “workation” instead of a vacation became equally more feasible. The borderline between remote work, “workation” and vacation has become more and more blurred. It remains to be seen, whether these options enhance an outsourcing trend by firms or whether  more “back-sourcing” or “in-sourcing” will be the consequence.
Employers with their associations and employees with their trade union representatives have a need to include such topics in their bargaining agenda in addition to pay, health and safety, as well as working time adaptations.

Vacation time

According to statistics from INSEE about 20% of the French population reported in 2024 that they could not not go on vacation due to financial reasons. Another additional 20% did not go on vacation for other reasons based on another survey mentioning other reasons, like psychological or logistical issues as being of overriding importance.
Openness to new experiences is a well researched concept of psychology and vacations can be a challenging time for established convictions. Meeting people from other cultures particularly allows to reflect on one’s own values and behavior. Some people may just want to avoid being challenged or even potentially destabilized. Destination time and place involve choices and decision making often within families or with friends.
The topic of vacation is much like an evolutionary process. Towards the end or some time after the vacation time, there is” evaluation time” and the preparation of the next experience.

Raffael Madonna

„Mary and the child“ has been the success painting of Raffael around the years of 1500. 3 variants on this topic are presented at the Gemäldegalerie Berlin. Each pose varies only slightly, but each tells a very different story. The Madonna changes the regard from beyond the child, on the child, then to another child. An interesting sequence as such, which puts the relationship with the child also in perspective. The child develops over the sequence from the fast learner into the person with „power grip“ to the one that is spreading benevolence. The different stages of the life course are somehow taking place within a short period of the child. (Image: Raffael, Mary with Child, Gemäldegalerie Berlin)

Age of maturity

The bronze statue by Camille Claudel „L‘âge mûr“ is her most famous works. It is part of the exhibition Claudel & Hoetger in the “Alte Nationalgalerie“ in Berlin. Usually the statue is part of the permanent exhibition in the „Musée d‘Orsay“. With the depiction of different stages of the life course and somehow revealing the emotional trajectories of the persons the scene of human joy and tragedy becomes tangible beyond her personal fate. The scenario and arrangement in the Alte Nationalgalerie allows to focus on this particular work with an emphasis on the trajectory and the evolutionary path. A unique arrangement does better justice to the particular message of the artist than being surrounded by too many other works of art. (Image: extract of Camille Claudel‘s „L‘âge mûr“ in showroom Alte Nationalgalerie, 2025-8)

Claudel & Hoetger

It is well known that artists joined other artists and groups to get inspired. The entangled relationship between Camille Claudel and Auguste Rodin has become a special example of the tricky relationship between learning and co-creation or inspiration. The role of galerists in building a reputation for artists is less well understood. The “Alte Nationalgalerie“ in Berlin opens up this black box a bit through juxtaposition of Camille Claudel, Bernhard Hoetger as disciples of Auguste Rodin. The influences are rather obvious, yet each disciple developed her/his unique style. The emancipation was not without frictions. The galerist Eugène Blot organized a joint exposition of both disciples in 1905 in Paris, which is partly reproduced in Berlin 2025. Great work by the curators of the exhibition Yvette Deseyve and Sintje Guericke who managed to bring together unique sculptures from 3+ museums and a great explanation of the links between the artists as well as the proximity of ateliers.

liberté urbanité

In the museum of the history of Paris “Musée Histoire de Paris Carnavalet” we find a special place devoted to the commemoration of the terror attacks in Paris in the Bataclan event location and the office of the journal “Charlie Hebdo” (see image below”. The skateboard on the bottom left of the wall raises the value of “urbanité” next to liberté, égalité, fraternité. The attack of an urban living style with youth going out as they like and journalists and caricaturists speaking their minds freely had been attacked, but continues nevertheless. This statement is part of the Paris state of mind.

Le Brun Selfie

The great painter and decorateur of the French monarch Louis XIV was Charles Le Brun. He was careful about the way he wanted to be remembered in history. His late 17th century self portrait is exposed in the Musée Histoire de Paris Carnavalet. Rightfully put in front of elegant red “tapisserie”, the selfie is remarkable for its attention to details. The hair is drawn with high precision and not a single one seems out of place. The painter does not focus on the person in front of him, but rather on some detail next to or behind the depicted Le Brun. The dress chosen is rather an ordinary person’s one or a person devoted to his work and artistic craftsmanship. No hands, no arms, no shoulders. The sole focus is on the head or should we say the brain and facial expression. Realistic painting is probably the closest you can get to today’s selfie-mania. Le Brun’s decoration and paintings in Versailles and churches ate probably some of the most popular backgrounds of selfiies even in the 21st century.

Home for dog

The places where some dogs live can be rather big. But even tiny dogs may enjoy a luxury home like their owners. This was certainly the case for the dog’s niche in a Paris home, a few years before the French revolution (1785). The exhibit is a testimony of the tough inequality of the late 18th century in Paris, where some enjoyed far reaching luxury and large parts of the population were forced to live in poverty within Paris or the suburbs with little access to basic sanitary facilities. The discrepancy between the luxurious homes of pets and the average person might serve as an indicator for income and health inequality. The Musée Histoire de Paris Carnavalet has a great stock of artifacts that can speak to the issue. Image: Musée Histoire de Paris Carnavalet dog niche 1785).

Photographe engagée

Marie-Laure de Decker is featured in the “Musée européenne de la photographie” (MEP) as a photographer committed to capture truth in situations of conflict. She started her career with documentary photos from the Vietnam war. Rather than searching for spectacular scenes, she succeeded in her attempt to capture the more emotional and, therefore, relatable moments for her various audiences. With a firm commitment to the human in her work, the photos by Marie-Laure de Decker reach a level of extraordinary sensitivity to what it means to stay human in violent situations and even military conflict. The portraits of politicians, workers, professions and famous actors applied the same approach. Rather than days or weeks Marie-Laure de Decker spent months or years in the regions of her documentary photo series ranging from Vietnam, South Africa throughout the apartheid regime, Pinochet years of dictatorship in Chile, the 2 parts of Yemen to a prolonged stay in Chad.

The exhibition in the MEP in Paris curated by Victoria Aresheva  raises awareness to the additional fact that photo journalism became an affordable profession only after specialized agencies were created that granted authorship rights to photographers, which ensured later use of their work in edited volumes as well as working for several newspapers or magazines. (Image: Marie-Laure de Decker, self-portraits, MEP Paris exhibits 2025-8).

Emotional history

The making of emotional memories of a city is an art in itself. Many cities have professional photographers who accompany all major events in a city over years. Paris has had the chance that artist photographers and film makers have contributed greatly to the emotional history of the city. Agnès Varda was such a formidable person whose images and movies moved people and allowed to share emotions about the city’s busy and diverse neighborhoods. The « Musée Histoire de Paris Carnavalet » combines an autobiographic perspective with the emotional depiction of live in Paris from the 1950s onwards into the late 20th century. (Image: Agnès Varda, 1950 self-portrait, MEP Paris).

Femmes Photographers

Paris puts 2 women photographer into the spotlight. The MEP and the Musée historique de la Ville de Paris feature a gender perspective on photography. Both photographers have a common starting point in black and white photography.  Each moved on to develop their art into an additional direction later during their career. Marie-Laure de Decker shifted from the early camera technology from black and white images to color photography in the later stages of her career. Agnès Varda moved from her initial b/w photographic work on to the production of videos for cinema, mainly focused on life in Paris from the early 1960s onwards. An evolution over the professional life becomes evident for both through these retrospectives of their respective work. Technologies evolved and became more accessible for artists’ creative expression. Both moved on to adopt new techniques and challenges. Great personal learning experiences and models for today’s challenges.

Gentileschi Heroine

The choice of a woman as heroine in a painting beyond religious topics was innovative in the early 17th century. Artemisia Gentileschi chose Cleopatra as her character in the ultimate scene of Cleopatra‘s life. The heroic act of guiding the poisonous snake to bite her under her arm is the ultimate act of Cleopatra to have served her country and people. As history books are full of male heros Artemisia Gentileschi succeeded in drawing attention to the biased gender stereotypes in art and art history beyond the 17th century.

Gentileschi Selfie

Today the production of „selfies“ is all around us. Selfies are shot almost instantaneously and several times a day by use of modern smartphones. About 400 years ago the first woman to produce a selfie was Artemisia Gentileschi. As (one of) the first female painter in art history to have created a painted image of herself (which is transmitted today) Artemisia Gentileschi made history. Her unique biography, style and craftsmanship of the early 17th century in Italy made herself a renowned painter. Her choice to depict herself rather than somebody nobel or rich was quite unusual for the time. The audacious choice of herself as her „sujet“ became even her trademark. Later paintings by her with biblical topics were also subject to her reinterpretation based on herself as the female character in the narrative and image. In this respect her work appears so much ahead of her time that her impressive work speaks to all generations today. (Image: extract of Jael and Sisera by Artemisia Gentileschi 1620, Musée Jaquemart André“ in Paris 2025-8)

Women artists

The history of art has been dominated in public opinion for centuries by men. However, recently art historians have drawn our attention to the numerous works of women who took Centre stage with their art during the last 500 years. Flavia Frigeri (2019, 2024) begins her history of women artists with Lavinia Fontana (1552-1614) followed by Artemisia Gentileschi (1593-1652). Both painters produced extraordinary paintings which brought their own touch to the paintings at a time when an independent expression through art was still largely reserved for men. The subjects of Gentileschi were greatly influenced by her experiences as a woman in a male dominated society in the 17th century in Europe. Her choice of subjects for her paintings added a female vision and depiction of biblical and historical narratives that were unique. The „Musée Jacquemart André“ in Paris featured a great retrospective of her art work in 2025. The catalog of the exhibition allows to enter into the art and wit of this early woman artist.

Zadkine museum

In the middle of Paris you will find a small former atelier of Zadkine. Transformed into a museum, the place is a cosy place to learn about sculpture and the different materials used. The preparations in form of designs or smaller trials with other materials are common practice to arrive at the sometimes monumental pieces. The visit of the permanent collection is even free of charge. A splendid experience in a surprising spot of silence next to buzzing city streets. Depicting musicians and musical instruments has been Zadkine’s shared passion with Valentine Prax. Great that he managed to reach the USA in time before the Nazi persecution could reach him. However, exile often means hardship as well.

Zadkine Prax

Ossip Zadkine and Valentine Prax once had their atelier next door to each other at art school. This established a lasting link between the 2. Whereas Zadkine became best known for his sculptures, Prax became famous as a painter. It appears that influences from one to the other are present in the works and several sculptures or preparations for sculptures were collected by Prax and found their way into the permanent exhibition of the museum. Intertwined biographies of artists are an inspiring reminder that art is not created only within a single mind, but many references or inspirations come from joint conversations or just working next to each other for some time. The social part of creating art is visible in this exceptional exhibition. Valentine Prax is honored with a presence in the Zadkine museum as well.

Zadkine Van Gogh

Ossip Zadkine has been a sculptor in cubists’ art tradition. He created famous sculptures of Vincent van Gogh after the death of the renowned painter and his friend. The Zadkine museum in Paris allows to get a great impression of these artworks. These sculptures reveal an interesting life course perspective on both artists sensitivity and transformation of their impressions of others or emotions more generally. The first study depicted below by Ossip Zadkine of van Gogh shows how he carefully studied the traits of van Gogh and his personality in order to better understand the evolution and death of the fellow artist. The emotional and broader psychological aspects of a character captured both artists. Doing justice to these inner feelings and society’s judgments about art and artists at their time of creation had strong impacts on both artists.

Air pollution dementia

A comprehensive review and update of evidence that indicates a link between air pollution and dementia has been published in “The Lancet” open access on 2025-7-25. Besides a genetic predisposition the environmental impact of our worsening air quality caused by fine dust particles and PM 2,5 and nitrogen dioxide NO2 has been found in several studies. This updated meta study should be an additional warning to take efforts to clean up our air more seriously. The diesel engines amongst other sources of air pollution have contributed a great deal to this evolution. Inner city inhabitants are at greater risks to suffer the consequences as they are more exposed to these pollutants and for longer durations. Clean air is a matter of brain health in advanced age and biodiversity as well.

Genetic diversity

Part of genetic diversity is the apparent fact that some partnerships have only girls or only women as descendants. This is the message of a study published in Science Advances by Wang et al. on 2025-7-18. The commonly assumed binomial distribution where each event has an equal chance of occurrence at each new point in time does not necessarily hold for this particular events. Therefore, the search for a genetic explanation has been going on for some years. Therefore, there might be a potential for an epigenetic explanation as well, as environmental conditions might co-determine the expression of genes in both parents. The research will surely continue and the sex and gender diversity offers still a lot of surprises. A sociologist’s perspective would tend to focus on later gender attributes and choices rather than sex at birth. The bio-psycho-social research agenda remains wide open.

Sedentary Lifestyle

There seems to exist a correlation between a more sedentary lifestyle and the level of industrialization. Industrialized countries have attempted to beat the running of time by faster modes of transport. From horses to cars, trains and airplanes. As a corollary of wanting to go faster the number steps walking has decreased compared to countries with less private or public means of transportation. The the time you spend sitting in transport the less we tend to walk or cycle. Obesity has become a dangerous consequence for large parts of those sedentary individuals and sedentary societies. The contribution by Paul Klotz in “Le Monde” from 2025-7-26 (p.24) highlights the bio-psycho-socio co-determination of the sedentary lifestyle. Societal developments to build entire cities more suited to car and train traffic has made walking the city a stressful task. Rebuilding our cities with a focus for a society on the move again is a challenge for more than one generation.

Electric Fun

The 60s, 70s and 80s have been fantastic precursors of the “All electric society” because of the electric music 🎶 industry that became a mass phenomenon. First of all the electric guitar allowed a wave of new music to take hold of a whole generation and probably keeps its adepts until today. E-pianos, keyboards, drum machines and synthesizers made music playing more accessible as well. You just need to plug in your instrument and you were able to produce an overwhelming sound. Other electric pleasures might include water pumps for water heaters and sprinklers. Electronic games and gadgets soon took over in children’s rooms. Of course, calculators as precursors of mobile phones and computers were another step in the progress towards the “All electric society”. Electronics are about to govern large parts of our lives and society. We better take a serious look at what we gain and what we might lose.

Just walk

The benefits of walking for several health outcomes is well known. The evidence is in favor of 7000 steps per day as a reasonable baseline. Some outcomes improve further if we walk even more steps, but not all. Probably, the effects of being accompanied while walking will enhance outcomes as well. Every summer the step threshold may be pushed a little bit further. Goal setting can help along to overcome eventual barriers to leave the home later in the evening. Nature rewards us with changing daylight and seasonal changes. We just have to get started to reap those health benefits.
