Polychrome tree

Maybe it is just a matter of taste whether you prefer a tree polychrome i. e. in full colors in spring or more monochrome during winter in almost black against a white background. Others might argue that it is not a singular version or time of the tree’s growth cycle, but the steady change. In any case the same tree never looks the same before and after rain. The only certainty is “the times are a changing”, so do our preferences. They are changing as well from time to time. Few persons have similar preferences over the life course and business, marketing and societal changes drive such changes. Often we hardly notice them. Trees are a perfect point of reference to check your personal preferences. Our smartphones track our preferences just by analyzing frequencies of photos taken over months or years. They have a very differentiated polychrome view of us. The reasons to take ugly pictures might confuse the AI-assisted exploitation of our polychrome or monochrome preferences. 

Retrieval-augmented AI

As a scientist it is in our DNA to cite other scholar’s work with precision. As a university professor your job is to check the quality of citations, kinds of citations and accuracy as a regular part of your job, also as supervisor of junior scientists. In 2026, the use of up-to-date AI (Asai et al. 2026, OpenScholar AI) allows not only to summarise large bodies of scientific literature, but also to cite references and even quotes from the paper(s). Literature reviews used to take months to compile. AI can speed up the process enormously. The citations can be ordered following an own logic or an AI-suggested logic.
It has become much harder to evaluate the degree of innovation of a candidate for a scientific degree. Tools like retrieval-augmented Language Models enhance the scientific potential of generative AI since they extract more or less short citations directly from the original source just next to the original based on a simple query of author and approximate subject (see screenshot below of own previous publication).
The good news is: (1) referral to previous research and citations should become faster with improved tools for verification. (2) You will find papers written by yourself that you no longer have in your own archive.
The bad news is: (1)self-citations of researchers might become more feasible, although this problem is conditional on a researcher’s seniority. (2) so far, Language models prioritise specific languages (although not necessarily) and differentiate names with “foreign” characters e.g. “ö,ä,é” and do not double check “close neighbours” of them like “o, oe, a, ae, ue, e, ê, è” leading to a “character based normalisation bias“.
It is, of course, rather easy to point out deficiencies of the search, sorting and inclusion algorithm if you know already about the complete picture of a data set. 

Being On Time

“Being on time” has a different meaning,  depending on the society and culture you are living in. Of course, this tends to reinforce stereotypes and raises expectations about the punctuality, the respect of time as a means to effectively synchronize human behavior and its interaction with technology. Train or bus services are commonly referred to in this context. However, our interest here is with the wider margins or, statistically speaking, the normal or not so normal distribution around a specific point in time.
Colloquially we refer to these time periods as being late (more common) or as being early (less common). Add to this perspective that you may be very late (early) or too late (early) and we are going to really deal with the spice of life. Just think of the last instances when you were late, very late or too late.
The same rationale of a “statistical view of time” can inform the sociology of technology. Some innovations can come too early for society to be ready to deal with it, or they may come too late to save us from disaster.
Genetic engineering of human cells is an issue in this regard, both too early for wider applications, but too late for persons in need of curing a specific diagnosis. There is an additional social-psychological aspect to the cognitive process of being on time. It is the cognitive dissonance of what you expect from yourself or somebody else and the actual experience of not being on time which causes stress. Societal norms of being on time can contribute substantially as well to the overall mental load associated with time. Take it easy.  

Silence revisited

In most cultures, particularly western ones, we are less and less used to silence. Keeping silent for 1 hour is almost framed as an exercise of meditation. In the presence of other persons silence is often misinterpreted as not being interested or even intelligent enough to contribute to the conversation or discussion. Therefore, the title of the exhibition “Seeing silence”, which rediscovers and honors the paintings of Helen Schjerfbeck. Her Finish, Swedish speaking roots, with a broad European training in the arts, made her an accomplished painter in the impressionist’s tradition with a focus on painting portraits. The catalog from the exhibition (THE MET 2025) gives a great overview of her paintings when silence of her models tell stories. Portraits of women are particularly powerful examples of tranquility, and reading, but also uneasy silence in rocking chairs. The biographical sketch of Helen Schjerfbeck by Dita Amory sums up the vocation as “All I desire to do is paint” (p. 15). Towards the end of the 19th century and the 1st half of the 20th century this meant work in silence and she chose to work on silence as well.  (Image: catalog in library Brussels 2026-2) 

Rule and divide leadership

We have known the leadership style, which has been coined as “rule and divide”, at least since the Roman imperial period.  In conquered countries it was a strategy to rule by way of creating divides between peoples or regions within a conquered country. The struggle for power within a country is likely to avoid that a powerful opposition to the occupant can build up. What is well researched in the history of international politics, has also been applied to the realm of management strategies. Anthony Galluzzo demonstrates that the strategies of management often attempt to split the workforce in at least 2 different camps in order to better keep employees and their trade unions under some sort of control. For society as a whole, so-called dual labor market theories have hypothesized the existence of such management strategies since the 1980s. With the labor practices in food and grocery deliveries as well as in taxi services such management strategies are applied again. “Old wine in new bottles”, but still seems to sell and catch on.

Collaborative Leadership

There are many reasons to praise collaborative leadership. Work climate, learning climate and innovation in teams and organizations benefit a lot. Absenteeism from the workplace is a proven and close correlate of hierarchical leadership styles. The theory and empirical evidence is rather clear in this respect, however the effective practice of collaboration among a leadership team is hard to sustain. Not only the ways to reach leadership positions is mostly rewarding tough elbows on the way to the top, the multiple rounds in the competition for top positions tend to train the toughest strategic  behavior. A return to more cooperation and collaboration appears to be a real challenge for persons that eventually arrive in top management positions in politics or business. Administrative science or organization science deserves much more attention especially if we are moving into the age of multilateral international institutions and multinational corporations and organizations. (Image: Les quatre parties du monde soutenant la sphère céleste, 1872, Musée d‘Orsay Paris).

Time in Leadership

We identified already the importance of monitoring in democracies. The same theoretical considerations hold for an analysis of leadership irrespective of the organizational context, be it a government, governmental organization, non-governmental organization, association or private enterprise. In democracies, it is in most cases a constitutional rule that leadership positions are limited in time and it is “best practice” to have clear rules about renewable terms of office as well.
In private enterprises this seems to be of lesser importance, but the issue deserves more close scrutiny, not only by shareholders in case of a shared ownership or stocks. A particular person in the leadership position might be a good match for a company at times of growth or scaling of a start-up, but the same leadership is less likely to be an equally good match for the period of eventual stagnation or shrinkage.
Therefore, as an alternative hypothesis it might be wise to adopt leadership rules similar to filling leadership positions with politicians. Fixed-term and 1 renewal could be worth testing at the leadership level (like in presidential republics, USA or France), even if this does not preclude close monitoring of leadership processes. As a starting point for empirical research, Vogel, Raes, Bruch (2022) offer a toolkit to assess organizational energy and leadership trajectories. Learning from democracies as well as democratic procedures might be a worthwhile leadership model to follow. (Image: ceiling painting in chateau  Vaux le Vicomte)

Regulation and bureaucracy

Economists will celebrate 55 years of the theory of regulation pioneered by George Stigler, which was published in 1971 in 2026. The basic question asked at the time and today is: why do we have regulation? The pubic choice and political economy answer of Stigler (1971) and many scholars after him, is that the industry of a specific sector will acquire the regulation or the public interest in this regulation and, subsequently, the industry will design and operate it to its benefits. At least, this is in a nutshell my summary of the literature inspired by Sam Peltzman (2021, p.20). If we add to this the perspectives of theories of bureaucracy (Sharma, 2020), we become skeptic of an efficient implementation of regulations by governments or governmental agencies.
In the field of pharmaceutical applications, it is the “European Diabetes Forum” which calls for a regulation on reliable “glucose monitoring devices” with industry and user backing. Of course, this asks for bureaucratic control of the regulation, imports and markets of such devices later on. The one (regulation) is rarely coming without the other (bureaucracy). It is about time to acknowledge this for societies as a whole as well.

Time and power

Who commands our time? Who commands your time? Both macro- and micro-level analyses of power relationships related to time need to be investigated. Time policies are most obvious when it comes to regulations of working time, permissions of business hours or so-called bank holidays. On the micro or individual level, it is often the question of who spends more time on work, care and repair. Hourly wage rates have been claimed by economists to guide or decide societal time spent on one or the other activity. An extension of this rationale with an overriding objective of happiness might considerably change the impact of power relationships on time. Longer time perspectives on health shall also shift the view of how power impacts the time spent on various activities. Time sovereignty is a precious value in its own right.
The power play between employers and employees keeps shifting the balance, albeit the overall trend over the last 100 years has been towards a reduction of working time and increased time sovereignty of employees as a form of democratization of working life. This constitutes one form to share the benefits of productivity gains over decades as well. (Image clock on Berlin City Council building on labor day 2025).

 

German Cinémathèque

The “Deutsche Kinemathek” in Berlin has moved to its new location in the old E-Werk. There is room for temporary exhibitions and screening on all walls. Small boxes (3 seats) give a brief overview of the history of television. The library is accessible again to the public. In order to research what went wrong in the history of mass media and cinema in Germany during the 1930s and 1940s can get access to the archives as well. In the age of new digital media technology the study of historical approaches helps to be aware of the power of persuasion of this form of mass communication. A critical thinking perspective on the material presented and the long history of cinema can bring generations together through the exchange of experiences with different media.
