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.

Tree as sculpture

Nature has lots of treasures to offer. A tree is just a splendid sculpture if we take the time to look at them. Over years, decades, sometimes even centuries, a sophisticated sculpture arises due to the imprints of sun, wind and rain over time. There are so many trees around us if we take care of them a little bit better . The simple appreciation of nature’s beauty can be the start of a longer journey. Many people remember a specific tree (Lindenbaum) that had some importance during their childhood or adolescence. Some even choose a tree to be buried nearby. Our life course reflects the growing of a tree. In some cultures you are considered an accomplished human being only if you have planted a tree. Examples of a miniature version of a tree are bonsai trees from the Japanese tradition. The real treasures of life might be just in your neighborhood.

Democracy in Nepal

Nepal has witnessed a peaceful revolution in which the young generation of Nepalis has “out-smarted” the previous rulers of Nepal. With close to a 2/3 majority of seats in parliament (Nepali Times), the RSP as the party of a somehow charismatic musician and performer has a 5 year mandate to tackle the many challenges to bring real change for Nepali people. The hopes are running high that corruption will be contained and enough jobs inside Nepal can be created for the young. The positive sign, that many Nepalis migrant workers who had left the country now return to Nepal, encourages further support by international donors and investors.
Running a democratic election in a country that comprises the Himalayan mountainous region is confronted with a particular challenge to make every vote count as communication with remote areas takes additional time and effort. Campaigning through social media can be more effective only if even remote areas have reliable access to the internet. Inter-generational assistance is often a precondition of timely access to information. The Himalayan region experiences already the effects of global warming as melting of glaciers. It is the youngest generation that will have to confront the consequences. Time to take government in their own hands, and beyond a one man show.

Bob the AI-enhanced builder

Most kids today and GenZ youth have come across the TV-series “Bob the builder”. Baby boomer parents have been worried about the work ethos which might be the hidden agenda of the videos. In 2026 we can now draft a new episode called “Bob the AI-builder”. Many episodes could be re-written when Bob and his team have access and get training with AI toolboxes. The study published by ActivTrak (2026-3-11) reports that companies make on average use of 7+ different AI-tools, up from 2 in 2023. This constitutes a hint that complexity at work is increasing as each tool has to be managed and the boundaries of its use need to be respected. As most search engines offer an AI-short cut to search it is not surprising that now 80% of the workforce use some form of AI in 2026. The productivity increases in quantitative terms as more output can be achieved in the same time or slightly shorter work days. However, workload is moved even more to weekends now.
The upcoming challenge through AI-tools is the reduced “the AI users’ focus time”, which suffered 9% compared to non-users. For Bob the AI-enhanced builder this means “AI is being used as an additional productivity layer, not a substitute for existing work”. The overall workload is not reduced by AI. The intensity of work increased between 2023-2025.
There is still a puzzle in the data. Multitasking (+12%) and collaboration (+34%) both increased, but the duration of an average focused session and focus efficiency dropped. The challenges for employees increase. Handling simultaneous processes and keeping an open mind to collaboration are key competences for Bob the AI-enhanced builder.

Fukushima Commemoration

The date of 2021-3-11 is marked by an event that according to science should not have been realistically expected by anybody. The probability of a meltdown of a nuclear reactor due to an earthquake and tsunami in Fukushima were simply beyond a “normal” statistical probability. And yet, it did happen. The consequences are still visible and the nuclear waste has to be dumped somewhere and lots of contaminated water has to be dealt with as well. 90.000 persons had to evacuate the area. Many of them have no interest in returning to the devastated area. Moreover, the psychological damage to the perceived security causes continuous trauma. The psychiatrist Ryoji Arizuka, interviewed for the French newspaper Liberation, reports that victims find it easier to cope with the “natural disasters” of the exceptional earthquake (9.0 on Richter scale) and the tsunami than with the man-made disaster of the meltdown of the nuclear reactor. Whereas the former disasters can be attributed to external forces, the latter example of a the explosion of the reactor is due to a failure to estimate the risk (technical, human and political) of an explosion properly by engineers and subsequently by politicians.
The commemoration of Fukushima by its governor Masao Uchibori in 2026 is a reminder that more risky technological progress comes potentially with higher costs to society as well. These “risks for societies” will have to carried by some selected regions. Solidarity with people who carry disproportionate amounts of risk should be “addressed” right from the beginning of the decision to use a risky technology, as an attempt to “internalise” the likely costs to society, eventually. Perceived cheap technology turns out to be very costly using different probabilities of associated even unlikely risks. (Image: Global stone project).

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.

Trust or not to trust

… that is the question. The social science research on trust, distrust or corruption is expanding rapidly. As in some other fields of research the increase in research itself becomes an issue of trust in science as the uncontrolled use of AI has produced an inflation of pseudo-scientific papers as well (Link). However, the finding by Spadaro et al. (2020) that interpersonal trust (trusting beliefs and behavior) is influenced by a general feeling of security as well as trust in institutions is supported by experimental and interview-based research.
There are still many challenges to the research in this field. The “feeling of security” has an overall component, but also several subcategories like the objective or subjective feeling of job security, which is dependent on national and collective systems of employment protection legislation. Economic security or security of a sufficient retirement income might be at times considered more important than (in-)security in cities or the countryside. Differences of the mechanisms by gender and age have to be studied in detail as well, which necessitates large data collections on the issues. Churches that used to be considered as trustworthy institutions or the police forces have been accused of abuses of the high trust placed in them in the last few years. These 2 examples demonstrate that trust itself is a dynamic issue with ups and downs over time, rarely constant over time. Game theoretical considerations add further to the view that trust might be used as a strategy just like economic power. (Image: Cathedrale de Meaux)

1000+ entries

From time to time it is useful to review whether a project is still on track or has developed biases, which may run for some time without reviews. Just like the United Nations Strategic Development Goals (SDGs) have been set 1bout 10 years ago, I do scan my own publishing project whether I still cover the SDGs in a larger spread. The goals need monitoring and I shall redo my own review as well.
As the number of blog entries on a daily basis has reached 1000+ entries, a review becomes a bit of a statistical exercise. As a kind of anniversary reward, a publication of more collections beyond the AI-reader or the Paris Olympics 2024 reader should be fun. However, there is so much work with checking and updating links, that the e-book, pdf and epub publications have become a time-consuming effort.
The search function implemented on this digital publication format is so fast and powerful that I am myself delighted again and again about the digging up of previous entries, concepts and evidence retained.
Time is a treasure and a value in its own right. Test it!

Visitor retention

For media, platforms, stores, webpages as well as blogs one of the more interesting measures about popularity or spread consists in visitor retention. It is a bit like counting the pages of a book you have read, which you have at home, or have you read them all? The zapping across radio or television channels is also an indicator or unsuccessful retention of viewers. Webpages, online stores or the blog entries here are all more or less directly trying to increase the retention of visitors on the same page. Maybe this can be considered as one of the first steps into a (not-so) social media addiction. The IT-sector offers tools for this.
On this webpage “schoemann.org” we make use of “linkz.ai” a ready-made plug-in that provides overviews on the links entered on this webpage, mainly to avoid that visitors have many additional tabs opened in their browser, do not jump off to follow up the links, but rather stay on the same webpage and “scroll on”. At the same time this means referrals from other webpages, which use the same techniques, will be less frequent.
The visitor retention tool used on this webpage is besides the original content 😉 “linkz.ai”. This tool scans other blog entries and links, and proposes the image on the previewed link at the top of the blog preview, for example. Basic weekly frequencies on previews are provided, which might guide a strategy to increase visitor retention, if that is one of your objectives.
The current discussion of addictive potential of social media platforms could be measured through such tools as well and has probably been used already for years with even more sophistication and direct feedback loops into the algorithms.

Fossil costs

On 2026-3-5 it has become sufficiently clear that the USA and Israel attacks to topple the terror regime in Iran have repercussions across the world markets of fossil fuels. 1973 and 1979 had told us already the lesson that a reliance on fossil fuels like oil and gas, which is produced in only a small number of countries, can disrupt energy supplies drastically. 50 years later we are much less vulnerable to supply shocks due to the stronger reliance on renewable energy sources. The supply shortages are only likely to happen, but energy suppliers are fast to cash in on these expected shortages. Prove of evidence that energy markets are driven more by expectations than actual availability of fuel stocks.
The advertisement of a Belgian recycling company “Powered by sunshine, driven by electricity” is a perfect summary of how to deal with shortages of fossil fuels (MCA recycling in Brussels, Image: former Brussels stock exchange).
