  1. The MOSAIC study addresses that the @who.int #HealthyAgeing concept "psychological capacity" lacks clear conceptualisation:

    #IntrinsicCapacity #HRQL

    The project has now published the definition and conceptual framework resulting from discussions in the International Working Group, which is now being further refined in a #Delphi study

  4. EN 13402 is a European standard for size labelling of clothes.

    Based on actual body dimensions measured in centimetres, its aim is to make it easier for people to find fitting clothes by ensuring size consistency across brands and countries of origin.

  5. New paper: "Valuation Without ℝ: A Category-Theoretic Foundation for Finite Measurement"

    Can measurement be formalized independently of real numbers AND set theory?

    We axiomatize "valuation" as a graded distinguishability map satisfying the ultrametric inequality. Dimension emerges as the growth exponent of the distinguishability graph.

  6. The Clock and The Calendar Didn’t Have to Look Like This

    Two of our basic time units are non-negotiable. A day is one rotation of the Earth. A year is one trip around the Sun. Nature hands us these whether we like it or not, no civilisation ever had to invent the day. Everything else - the week, the month, and even the hour, minute, and second - is a human invention layered on top. Nothing in physics requires 24 hours, 60 minutes, or a 7-day cycle. We made all of it up. And the fact that nearly every civilisation independently arrived at something […]

  7. NASA's Parker Solar Probe Flew In And Out Of The Solar Corona And Found A Source Of High-Energy Particles That No Existing Model Had Predicted
    (When NASA's Parker Solar Probe passed through the solar corona during perihelion encounters at the heliospheric current sheet, its instruments recorded energetic protons at energies far above what existing models of particle acceleration at that location could account for.)

    “… A team… at the Southwest Research Institute… and… the University of Maryland’s Institute for Research in Electronics and Applied Physics has published an analysis of those measurements [link above]…, identifying magnetic reconnection at the heliospheric current sheet as the mechanism responsible. The proton energies detected were, in the study’s framing, approximately a thousand times greater than the available magnetic energy per particle that models of this process had predicted.
    The finding matters for two reasons: it identifies a source of energetic particles close to the Sun that was not anticipated, and it raises questions about how far the existing understanding of reconnection-driven particle acceleration extends…
    The Parker measurements suggest that picture needs revision. The magnetic island merging mechanism [the authors] identif[ied] can evidently produce proton populations at energies that challenge the boundary between what reconnection does and what shock acceleration does. Whether this source can explain a significant fraction of observed near-Earth energetic particle events, or whether it contributes mainly at energies and scales that remain confined close to the Sun, is a question the paper does not yet resolve…
    Solar Orbiter, the European Space Agency mission operating in coordination with Parker, offers complementary measurements at somewhat greater distances. Comparing what the two spacecraft measure of the same particle populations as they propagate outward from the Sun will help establish which features originate close to the source and which are modified by the intervening solar wind. The energetic particle observations that puzzled researchers in the pre-Parker era now have a candidate mechanism. Whether that mechanism accounts for a large or small fraction of what actually reaches Earth remains the open question…”

  9. 7 years ago, I wrote a blog entry about more imperial units, where I suggest new imperial units that convert somehow to metric.

    Of course, XKCD managed to present a much more compact formula that binds imperial miles to nautical miles…

  10. Some pretty obvious and standard things are described here as novelties:

    Basically:

    1️⃣ #Leaders exist because they have #Followers,
    2️⃣ Leaders are here to provide #Guidance within the #Regulation and #Control “hierarchy”
    3️⃣ All #Measurement is personal and beneficial only to the measurer
    4️⃣ The “hated” #Matrix organizations are connecting silos
    5️⃣ Removing what is #NOT determines what IS #Possibile (the cone of possibilities)
    6️⃣ Groups of people will form #Living systems that cannot be engineered but can only be maintained as a “garden”
    7️⃣ #Negative feedback is the only useful #feedback. A “pat on the back” never helped anyone. 😀

    Also, this is all set backward:

    How can we ensure there are useful leadership Artefacts (tools, processes) and leadership Heuristics (rules of thumb, ways of doing things) - as well as Skills, Experiences and (of course) Natural talent.

    I understand that as a consultant you have the “urge” to sell something tangible (a product) but you always have to start with the #People and their experience, skills, and natural talent, then identify the #Processes, what they do, and how are they connected (collaborate). Selecting the #Products (tools, SW, forms, space, facilities) that will support that is the last and the least important thing.

    Btw, a process is not an #artifact (product). Only the “rule book” that describes the process is, and there is a huge difference between the two.
