  1. Bad News

    Me:-

    "Are broken-up people (like me) given the same care and attention as the divorced?"

    Claude:-

    Honestly? No, and that's a real gap.

    Divorced people get:

    • Social acknowledgment ("oh, they went through a divorce")
    • Community support, family sympathy
    • Religious frameworks (iddah, counselling, clear closure)
    • Legal process that forces some kind of finality

    Broken-up people often get:

    • "It was just a relationship, move on"
    • No formal closure ritual
    • Grief that isn't publicly recognised
    • The expectation to be fine faster

    This is called disenfranchised grief — grief that society doesn't officially validate. The loss is real, but because there's no contract, no ceremony, no legal ending, people around you often don't treat it with the same weight.

    Me: "Very sad news indeed. I am just a fly in the skies that's broken."

  2. OMG Social media improvement idea!
    Option to publish individual posts to be, allowing no further edits except emphasis.

    Like, you can change the formatting forever onward to be:
    "make this bit bold", "italicise the other thing", or "strike-through that", "underline whatever".
    Maybe add a redaction feature, in case you want to keep a post up, [but remove sensitive info you left in].

    Or redact any hacked or bot posts, leaving that portion up as, like, "hey this is when stuff got annoying".

  3. Core outcome sets are a strong tool to improve quality of and communication about research, but especially to align PRACTICE and research. A #COS for #depression has the potential to move the dial considerably:

    The PROCEED study identified outcomes for #depression that matter to patients, caregivers, #healthcare professionals, an excellent read:

  4. A #SysReview of quality of life and #HRQoL instruments used in trials of interventions for adults with alcohol use disorder:

    One of the interesting findings:
    Although the team focused on the most frequently used instruments they found only very few studies reporting psychometric properties in this population.

    This mirrors findings from our broader #SysReview of #HRQL as an outcome in substance and behavioural addictions

  5. Improving Numerical Measures of Human Feelings: The Case of Pain d.repec.org/n?u=RePEc:lan:wpap
    "… proposed and validated a new method to measure the experienced intensity of acute pain across individuals. This method proved to be overwhelmingly more accurate and sensitive than standard, established methods for experimentally-induced acute pain which are used in medical, clinical and research applications
    … In the case of experienced pain intensity, the mechanism that enables the new #measurement method to excel might indeed be rooted in its well-calibrated scale: #money.
    … Money-free standard methods ask people for numerical estimations of their experiences without a benchmark for the numerical scale, which might lead them to choose salient numbers or intermediate values.
    … Monetary amounts provide interpersonally comparable references and thereby reduce the intrinsic subjectivity in pain measurements.
    … The use of monetary incentives is unproblematic for those applications, as it is already common practice to reward participation in them"

  6. TL;DR: It's not a psychometric scale and it's not weebly

    This "Weebly racism scale" has been posted a couple of times on the Fediverse, and I finally decided to look it up. It seems like a multidimensional construct reduced to one dimension, so I wanted to see the items, hopefully an exploratory #FactorAnalysis, evidence of #reliability and (dare I hope?) #validity.

    Yeah, no. It's not a scale at all, in the psychometric sense. No data collection or #analysis (AFAICT) was part of this, so there is no (and, at this point, can be no) validity information.

    This is one person's ideas about racism. This is absolutely the kind of thought work that should be done when one is at the very beginning of scale creation, but it's not a scale like that.

    The scale is hosted on weebly dot com, a web host kind of like squarespace.

    The fact that hundreds (or thousands) of other people resonate with this scale is a good sign for potential validity. However, that is not sufficient psychometric evidence to call this a "racism scale" alongside things like the Modern Racism Scale, etc.

    This seems like a useful activity to get you thinking about your experiences with racism (on either side of that line), but because it's not a psychometric scale, there's no *scientific* reason to believe

    * The implied or explicit categories map onto actual racist thinking/behavior patterns

    * The order of the categories is valid--e.g., there's no evidence "I'm not racist but..." is more racist than "'Funny' Black Face", etc.

    * The categories even belong on the same continuum

    As I said above, it really feels like a decent start, but with several dimensions squashed into one. I'd personally love to see a racism researcher use this to develop an actual scale, or try to. I suspect the result would be something vaguely resembling this scale but with significant differences.

  7. #Is the #Debt #Limit #Constitutional?

    The 14th Amendment states that “the #validity of the #public #debt of the United States, #authorized #by #law ... #shall #not #be #questioned.”

    Some legal scholars contend #that #language #overrides the #statutory #borrowing #limit, which currently caps federal debt at $31.4 trillion and requires congressional approval to raise or lift.

    “The Constitution’s text bars the federal government from defaulting on the debt — even a little, even for a short while,” Garrett Epps, a constitutional scholar at the University of Oregon’s law school, wrote in November. “There’s a case to be made that if Congress decides to default on the debt, the president has the power and the obligation to pay it without congressional permission, even if that requires borrowing more money to do so.”

    Other legal scholars say the limit is constitutional. “The statute is a necessary component of Congress’s power to borrow and has proved capable of serving as a useful catalyst for budgetary reform aimed at debt reduction,” Anita S. Krishnakumar, a Georgetown University law professor, wrote in a 2005 law review article.

    The president has repeatedly said it is the job of Congress to raise the limit to avoid an economically catastrophic default.

    Top officials, including Ms. Yellen and the White House press secretary, Karine Jean-Pierre, have sidestepped questions about whether they believe the Constitution would compel the government to continue borrowing to pay its bills after the X-date.

  8. I'm thinking about how to relate #ModelBuilding and #ModelEvaluation to #OpenScience. I'm not there yet, but anyone who wants to think along, feel free! Model evaluation, thinking about #validity and how #standardization and #generalisation interact, among others...

    Figure on #standardisation vs #generalisation from doi.org/10.1111/j.1601-183X.20
