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.

Draft Lottery

For decades the “intergenerational effects of the Vietnam draft on risky behaviors” has been overlooked. Deza and Mezza (2025) identified several changes in parenting styles (PS) due to existence of a draft lottery. PS like uninvolved, permissive, authoritarian become more frequent. Similarly, risky behaviors of their children like smoking, drinking and drug abuse tend to increase. According to this new evidence on an old strategy to recruit military personnel the effects are not only directly on the persons drafted, but have lasting consequences onthe next generation as well. This increased overall the burden of going as well as preparing for war in the societies concerned. In view of the Russian aggression on Ukraine territory the consequences for both countries are considerable and shall be transmitted to future generations as well. Even neighboring countries fear and feel the heat of recruitment for armed conflict.

 

Maison de santé 1861 Berlin

In the middle of the 19th century Berlin was a small city. The area of Schöneberg (pritty hill) was still perceived as the rural outskirts and featured the first botanical garden next to the town center. A little bit more outside of Berlin the “Maison de santé” was founded as early as 1861 to cure mainly respiratory diseases and what later became the first private clinic proposing a new way to treat psychiatric disorders. Dr. Eduard Levinstein was the founder and the clinic had continued its operations for almost 50 years with his wife and sons taking the lead later on. Prof. Wilhelm Griesinger, known for the scientific approach of psychiatry was a proponent of the non-restrained approach to psychiatric disorders, which allowed persons move more freely while being supervised. The documents and the publication (1877) shown in the exhibition at Museum Schōneberg demonstrate the scientific approach to the treatment of addictions, most notably morphine, which had been widely used during the war of 1870 as tranquilizer and pain relief. The wave of addictions needed hospitals and clinics to treat these addictions. The “Maison de santé” had been established as a retreat and cure for other addictions as well. The memory of the early scientific approaches is an inspiring place and reminder to take care of all forms of addiction. Taking care of body and mind is still the state of the art approach today.

The Exhibition catalog is forthcoming, but the visits and material on display of interest beyond the inhabitants of the „Pritty Hill“. Exhibition catalog is forthcoming

Wellness Sickness

There appears to be some kind of a relationship between the 2 conepts of wellness and sickness. Some would argue that the more sick you are, the more you seek wellness. Sickness seems to be the precursor of wellness for many people. Wellbeing or happiness are even higher order concepts which are only indirectly related to wellness. In an almost 600 pages science and fiction novel, Nathan Hill (Link) constructs his plot based on the psychological research on the placebo effect. With a sufficient aura around a pseudo-medication administered in a wellness clinic, the clients or some figure near the 50% random positive effects are treated with at least no negative side effects. On page 152 we find the more explicit description of how to induce a placebo effect in participants. Context, expectations, faith, symbols, metaphors and story are all ingredients for a placebo effect to work. Sometmes without knowing we receive a treatment in our childhood or throughout the life course that we work on using placebo effects to overcome them. The novel by Hill (2024) is a well researched psychological as well as sociological fiction including a bibliography, which reminds us „If you cling too hard to what you want to see, you miss what’s really there.“ (p. 496).

Cannabis Alcohol

The use of cannabis and/or alcohol is yet another question where we are used to ask questions in the form of: either the or the other? Over generations we have gotten used to no longer ask for each do you or don’t you. With the controlled liberalization or legalization of cannabis in some Western European states the framing of the question is more like you do the one or the other, particularly for many younger persons.
Decriminalization of both drugs in small quantities is apparently reducing crimes link to drug use and drug dealing. On the other hand, the thresholds for doing drugs are lower than they used to be. In inner cities it is therefore no longer a surprise to find both kinds of drugs with addictive potential next to each other (see image below). We know that it is a slippery road from regular drug use to uncontrolled dependency and personal disaster. For cannabis a study published in the Lancet (Petrilli et al. 2022) added the importance of the potency of tetrahydrocannabinol to the estimate of risks. This is similar to the studies that differentiate the level of alcohol in drinks consumed. The higher the concentration, the higher the risks. A simple proportional relationship prevails in both drugs. The cumulative effects of consuming both together might have quite surprising non-linear effects.
The big issue is the risks of mental health related to these drugs. However, the causal direction is not easy to detect. Drugs induce mental health problems, but also mental health issues lead to drug abuse. This remains quite a puzzle for scientists to disentangle.
Additionally, the link to smoking and addiction to nicotine is a frequently observed corollary. Studying just one single source of health problems and addiction might be too restrictive to learn about the whole set of causal effects and casualties. For the time being we seem to jump from one field of attention to the next one ignoring the multiple interrelated factors at hand.
