The Cervimeter, Centimeters, and the Friedman Curve: A Historical Case of Imprecision Medicine
Rebecca Jackson, PhD
Bridging Fellow in Medical Humanities, Department of Philosophy at Durham University and the Measurement Lab within the Institute for Medical Humanities and Discovery Research Platform for Medical Humanities

Abstract: In 1954, a young medical resident created a new dimension for measuring labour: change in dilatation rate over time, which he saw as allowing the woman’s own body to participate in the definition of what it meant for labour to be “arrested.” Yet, in constructing a “normal” standard curve of dilatation-over-time for guiding labour decisions, and constructing a “cervimeter” to be the (so-called) objective instrument for evidencing the shape of this curve, he unintentionally enabled a new dimension of labor to emerge: centimeters of dilation, today read as the state of labor progress. This talk explains how Emanuel Friedman’s cervimeter was key to evidencing his claims about the “sigmoidal” shape of the dilatation curve, originally intended to test research claims about caudal anesthesia. I explain how the cervimeter reified centimeters as a metric unit to be used for the measurement of labor (rather than merely an ordinal approximation of one feature) and enabled the later transformation of Friedman’s Curve from a graphical tool which was meant to conform to women into a tool which was used to conform them.

VIDEO – Apr 29 Cybersecurity SIG – Measuring Internet Security Resilience

On 29 April 2025, the Internet Society Cybersecurity Special Interest Group (Cybersecurity SIG) meeting included a presentation 'Measuring Internet Security Resilience'. Robbie Mitchell provided an overview of the Internet Society’s efforts to measure the resilience of the Internet with a focus on Pulse - a website that consolidates tru

Thoughts: Not my cup of tea. But useful package. Useful vignettes also.

Hey everyone!
I’m looking for a good way to create a #graph or #chart from a #dataset under #Linux.

The data is in a #CSV file and has around 180,000 rows. One column contains the timestamps, and several other columns contain the actual #measurement values.

Not every value is recorded at every timestamp, so there are different sampling rates across columns, and some fields are empty. The solution should be able to handle that – missing data, large file size, and multiple series plotted over #time.

What’s your preferred tool or approach for this kind of visualization?
Ideally something easily repeatable.

Got a new #laundry basket yesterday, which came marked in one of the most useful and ubiquitous #units of #measurement, the bushel. 1.75 of them. That's almost 62 liters, for people in civilized #metric lands.

1 Scaramucci = 11 days
1 Hegseth = 88 days (so far)

The current conversion rate: 1 Hegseth = 8 Scaramuccis.

I don't think Pete Hegseth is going to equal 9 Scaramucci.

`Unlike any other clock, this quantum watch does not utilize a counter and is fully quantum mechanical in its nature. The quantum watch has the potential to become an invaluable tool in pump-probe spectroscopy due to its simplicity, assurance of accuracy, and ability to provide an absolute timestamp, i.e., there is no need to find time zero.`

volumetric measurements in the kitchen requires remembering which spoon you used the last time to define your volume. this is especially true when starting out and you don't yet have the feel for quantities.

Improving Numerical Measures of Human Feelings: The Case of Pain https://d.repec.org/n?u=RePEc:lan:wpaper:421926304&r=&r=exp
"… 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"
