World University Rankings 2021

The rankings are based on 13 performance indicators, which are separated into five categories: 30 percent teaching (the learning environment); 30 percent research (volume, income and reputation); 30 percent citations (research influence); 7.5 percent international outlook (staff, students and research); and 2.5 percent industry income (knowledge transfer).!/page/0/length/25/sort_by/rank/sort_order/asc/cols/stats

We all know that the weights are far from being objective, but we also know that they are not random. So, we cannot do better just to navigate between objectivity and subjectivity!

Top 100 Most Influential Economists in the World (2020)

A new Top 100 list was published by Richtopia: The list is admittedly reflects social influences measured by digital reputation. Paul Krugman looks to be the clear winner.

Here are the details

As you may know, I think “There are three different dimension of your reputation: who you ARE, who YOU SAY you are, who PEOPLE SAY you are. The first characterize your personality and identity; the second reflects your communication strategy, and expresses how you would like to be seen (as the cat says, ”I would like to be seen as a lion”; the third says how other stakeholders participate in the game describe you and your activity.”

Like it or not, ranking is with us.

Thank you!

I would like to thank you my friend, Fanji Gu, that he translated Ranking to Chinese (with simple character.) The book will be published by Shanghai Educational Publishing House. Special thanks to the Publisher/Editor of the book Wei Huang, who liked the book, and supported the translation.

From Ranking to Repair!

While the world is disrupted,  ranking is still with us.  I am sure many of you are too familiar with the new Ranking game  .  I also believe, together  with many of you, that the world – for better or worse – will not be the same, as it was.

As concerns the Ranking book itself, it looks that so far the German, Chinese (with simple characters), Korean and Japan translations have been licensed, and the Hungarian translation seems to be plausible. Assuming we will have some reasonable Fall,  I will teach a class at University of Michigan about Ranking.

From mid-December  I am thinking about the plan of new book with the working title REPAIR! How to Improve Broken Objects, Ourselves, and Our Society. It looks I will have a co-author, the Hungarian social psychologist Zsuzsa Szvetelszky .  Here is a paragraph from the draft of the book proposal:

The question of when to repair and when to replace objects is always with us. We could mention a number of illustrative phenomena. Many of us are suffering with the problem of broken friendships, and we ask ourselves whether or not they can be mended. A stopped clock can be repaired, but a burned-out light bulb must be replaced. A bulb, however, is replaceable. It would be ridiculous to throw out your whole crystal chandelier with sixteen lights (as part of your family inheritance) if one of these lights does not function. But sometimes big companies adopt business policies that do not provide access to spare parts, and a whole new gadget must be bought. The “right to repair” movement started a legal fight to allow consumers to repair their broken electronic devices by being able to buy replacement parts at a reasonable price. So we also review the possible change of the attitude of people from living in a throw-away society to accept consumption reduction.

We prepared an article as a response for the open call for the Hungarian social science journal Replika . You can download the paper from here:

Hope the Reader is well!

How to rank patients for treatment?

As coronavirus cases grow, hospitals adopt a system to rank patients for treatment

a point system calculating a patient’s likelihood to benefit from ICU care, based on two considerations: 1) saving the most lives and 2) saving the most life-years.
The lower the patient scores, the higher their prioritization for care. In the system’s eight-point scale, the first four points illustrate the patient’s likelihood to survive hospitalization, and the last four points assess whether, assuming they survive hospitalization, they have medical conditions associated with a life expectancy of less than one year or less than five years.
For the science behind the scoring system read this executive summary
