Forecasting floods

As floods as becoming more frequent and more severe forecasting of such events is crucial. The recent example in Bavaria (Germany) of the Danube river (2nd longest in Europe) has demonstrated the role of forecasting to spur adequate behavior of people living in areas at risk of flooding. With the weather forecast announcing lots of rain for a large area the forecasting of floods needs to follow closely these trends. It is not only a question of expectations, but an issue of adaptive expectations for people to adopt appropriate precautions. In retrospect the early forecasts turned out to be fairly accurate in terms of the peak of flooding to be expected in June 2024. The Bavarian “Hochwassernachrichtendienst” (no joke, one word) forecasted on the 2nd of June about 7.50 as the peak to be reached in 2 days in the city of Kelheim. This was beyond the usual 4 warning levels based on an escalation scale. The forecast was beyond the frequent flooding levels established in the last decades. People and emergency services would have to adapt their expectations accordingly. Renewing forecasts is essential to guide people and services in their efforts to deal with emergencies and repair damages as flood levels recede. Management of crises critically depends on forecasting even if they are obviously prone to error margins which should usually be reported as well just like in weather forecasts. Adaptive expectations are key in combination with forecasts to ensure survival.

Adaptive Expectations

In economics it is important to understand the concept of adaptive expectations. We all form expectations about prices and inflation, but there is more than just simple expectations. These expectations guide our behaviors in many domains. If we expect a drastic price change for goods and/or services we shall most likely modify our behavior in response. We might want to advance a purchase to take advantage of currently lower prices in the expectation of higher costs later on. Most people would follow the price changes on a regular basis and adapt their expectations according to the updated information. It is an important process as there are millions of people who do this and this process drives price levels in many countries. In Europe we would like to see not only inflation, but also expectations about inflation to be around the target level of 2% per year. After the high price rises of energy and food (Putin’s war) as well as the disrupted supply chains (Covid-19 crisis) we were unsure, whether we would have to adapt our expectations for the coming years. The credit crunch in the last few years forced people to adapt spending plans and expenditures. We seem to have overcome these major crises due to rapid adaptive expectations. The crucial mechanism to achieve this is a timely and open communication of changes. Media have a role to play to not only spread the information, but to explain underlying reasons. This contributes to a widespread understanding of basic economic principles that helps countries to navigate stormy weather. It is like players of chess who adapt their strategy after the other player has acted or not according to their expectations. It’s simple, isn‘t it?

Co-authorship Kafka

In science Co-authorship is a tricky issue. Therefore, many higher reputation journals list precisely who has contributed what to the paper. In the teaching and supervision of bachelor, master or doctoral dissertations it is imperative to scrutinize the original contributions of authors to the subject. There are huge differences between universities to the amount of innovation or originality that is required to award degrees or the publication of the research and results. Rüdiger Safranski published with Hanser 2024 an essay on Kafka which has 224 pages, but a 16 page long list of the sources of the copy-paste citations used from the orignal Kafka writings. By scientific co-authorship practice Kafka should claim co-authorship of the book and the costs of the „Process“ should be paid by the publishing house. However, I enjoyed the many links between comments and the originals next to each other. It is like a data analysis that sticks plausibly to the original data. AI still has a hard time to rival with these skills, although AI is catching up faster than many of us might believe or want to believe. From a social science perspective we might say the original work of maybe only 180 pages is inflated to make for a longer text of 240 pages. This justifies, probably, the publisher’s price (€26) and the marketing costs. On the other hand it becomes evident that Kafka has an enormous impact on writers and seems to take possession of them in an encompassing fashion. You move with him, but rarely beyond him. Tough lessons indeed from the publishing world.

Portable Grundgesetz

Celebrating democracy in Germany is rare. We take it for granted that democracy persists, as most of us have not experienced it otherwise in Germany. This is grossly mistaken as the opinion polls show repeatedly in recent years. Therefore, it is welcome to find the “Portable Grundgesetz” at the “Demokratiefest” in Berlin and Bonn at the event to celebrate 75 years of democracy in West Germany and 35 years in East Germany.
The century-old tradition to produce miniature books has been revived and the miniature books have been widely distributed at the event. A side effect consists in the eco-friendliness of this version, which saves a lot of paper. It is fun also fun to turn pages rapidly and discover some paragraphs which we would not have read otherwise. “Daumenkino” is the German word for versions that contain many images. Maybe next time, an illustrated and/or animated version of the Grundgesetz could encourage youth to celebrate using the texts, §s and images to discover the fundamentals of our constitution.
325 years ago, Weigel the Elder has illustrated, edited and published such a tiny edition of the Bible. It is currently exposed in the treasure museum at the “Kulturwerk” in the “Stabi Ost” in Berlin. “Back to the Future”, lots of ideas we get by taking archives seriously. By chance inspiration is undervalued. Search algorithms have a hard time to replace this in an effective way so far.

Democracy celebrates

With all the bad experiences of Nazi-Germany and the failure to defend democracy in Germany against its fascist enemies in the 1930s, it was a pleasure to celebrate democracy in Germany together with a huge crowd. 3 days of information and party around the major institutions of democracy Parliament, government, federal governments, constitutional court and all ministries joining in with pavilions in the parks nearby allowed a bottom up feeling of democracy. Visiting the chancellery as well as the parliament in a single day shows the openness of these institutions and the ease of access to our political system. People of all ages and all walks of life strolled around and enjoyed the day. Freedom to voice your opinion was easy and many took their time to do it. Civil society organizations were a natural part of the show. We seem prepared to stand up for our democratic values and principles. This will be tested in all the forthcoming elections.

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.

Camparing Covid-19

In the middle of May 2024 we tend to believe the Covid-19 pandemic is over. However, towards the beginning of the year 2024 in the U.S. we observed at the peak about 2500 deaths per week. In Germany deaths/week amounted to 250. Compared to the overall population size killing is more pervasive in the U.S. than in Germany. The map of the specialized agency “Centers for Disease Control and Prevention” (CDC) in the U.S. shows the coastal regions to be more affected than the center. Population density seems to be still a driver of the spread of infections, illness and deaths. The timeline of deaths due to Covid-19 infections for Germany follows a broadly similar pattern, albeit on a lower level even if roughly accounting for population size (RKI-data). As we tend to forget what the pandemic caused as social and economic disaster in societies, we have to stay alert as the major prevention of Covid-19. Learn to live with the virus around us. This means to keep up our preventive levels of hygiene as well as monitoring of trends.
Many thanks to all those who do the sometimes boring number crunching for us. This includes the medical doctors who bother to do the timely reporting of new infectious diseases on a regular basis.

Barbie Chemical

Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.

Photos Exhibit

Our usual expectation of an exhibition of photography is to look at photos at a wall. Sometimes there is more it. The Exhibition Space at the “Haus am Kleistpark” features Michael Schäfer who attempts to go a bit beyond these traditional forms. In the works of photo cubes on water surfaces “2021_57”, or a dice floating on the waves of oceans, the video representation of his photographs takes the assembled images beyond their flat 2D surface. However, the 2D representation is at the origin, then transformed into a 3D dice, which then is animated as a 4D format. Moving beyond the flat screen image takes photography into the 21st century.
His work “Les acteurs 1-26” from 2007 is shown at the entry hall of the exhibition. It shows pupils of a class at an elite school who deem themselves in leadership roles in the near future. Is it acting? Is it projection into a future role they are likely to take on. They represent stereotypes, of course, but some are pretty convincing in these roles already. Some others still seem to reflect on what they are doing there. Even acting these roles, they are aware of the meaning of social rank and class in society. Without having read the sociologist Bourdieu, all are aware of the fine, little elements of distinction as they have evolved over time. We could teach an interesting sociology class in this exhibition.
