@richardepryor @campbellclaret @BorisJohnson Reminds me of Heseltine's assessment of Johnson's leadership: a "man who waits to see the way the crowd is running and then dashes in front and says, ‘Follow me’."

@BorisJohnson Basically write down a summary of what the EU and US and NATO have already committed to do, and are doing, and do that. True leadership huh?!

Putin must fail and must be seen to fail in this act of aggression. We must come together under a six point plan of action to ensure Putin fails in his ambitions. The world is watching. It is not future historians but the people of Ukraine who will be our judge.

@ReubenODea Carefully worded, plausible-sounding deceitful bol*****? Yep, much better. You bring out the best in me

English

Reuben O'Dea@ReubenODea·24 Şub

Baffling justification is certainly one (incredibly generous) way of putting it. I hadn't read the staff news email until I saw this thread, as they too frequently make me depressed, angry and exasperated. Now I'm depressed, angry and exasperated. #USSmess

Simon Preston@simonpreston

@wilkinson_rich @UoNUCU "Too many members of staff are currently choosing not to participate in USS because the contribution rate is too high, or the scheme benefits are not considered suitable" is baffling justification given it refers to a status quo which is about to be made severely worse

English

Simon Preston@simonpreston·24 Şub

@MarkusOwenMMB @wilkinson_rich @UoNUCU @MikeOtsuka You're right - per point 6 here, opt out rates actually appear to be dropping! I was irritated by the silly logic of that quote, but even worse: it seems plainly deceitful twitter.com/MikeOtsuka/sta…

@wilkinson_rich @simonpreston @UoNUCU It’s also misleading to suggest that opting out is becoming particularly more common: “2020 16% opted out … in 2015 that figure was 21%, with a dip to 12% in between.” leedsucu.org.uk/opting-out-of-… Seems rather difficult to find opt-out numbers - any ideas @MikeOtsuka ?

English

Richard Wilkinson@wilkinson_rich·23 Şub

In today's Staff News email: "Members earning above the threshold [will] receive a 20% defined contribution into their individual pension pot." No. We will receive 10.2% and will contribute the other 9.8% ourselves. Why spin everything? @UoNUCU

@wilkinson_rich @UoNUCU Meanwhile we're being invited to the next USS Roadshow when we'll be updated on the "consultation process". Am so angry at this

English

Simon Preston@simonpreston·23 Şub

@wilkinson_rich @UoNUCU "The JNC’s decision was confirmed with the vote of the independent chair" is spin for "The decision only passed on the casting vote of the chair, who sided with UUK and against UCU"

I have covered UK university sector disputes over #pension cuts since 2017 and can say that I have not seen members so angry as they are today over fresh cuts to their retirement benefits. The anger has reached a new depth. This does feel like a turning point. #USS #UUK #UCU

@sp_monte_carlo ... then simulation just involves drawing a sample from a MVN then rescaling to unit norm. (the kind of easy simulation that I like :-) )

English

Simon Preston@simonpreston·7 Oca

@sp_monte_carlo Another possibility, if efficient simulation is important and one isn't too tied to the VMF model, is to work instead with an analogous distribution in the angular Gaussian family, e.g. link.springer.com/article/10.100…

cool visualisations of distributions on the sphere (from doi.org/10.1080/036109…)

Simon Preston@simonpreston·5 Oca

@GaryMirams @BBCNews @GregMcI I don't like these plots very much for that reason. Just plotting a line for each - and a line for the total if that's important - usually feels clearer (to me at least)

First neutralisation data from @sigallab. Live virus, small number of sera (but obviously very important study). That's 40 fold drop compared to D614G, essentially variant against which original vaccine efficacy was determined (NB does *not* mean 40 fold drop in efficacy).

@AlistairHaimes @timspector Good news, of course, but article qualifies with "However, this is not unexpected given the young age of the participants." Plus v small sample size. Doesn't feel to me like we can read much into this. Still🤞

@timspector But "the individuals infected were so far displaying mild symptoms, with none hospitalised."

Now some 80-90 of the 120 are PCR pos, 13 of these confirmed omicron, the rest waiting for sequencing results. Some of those infected w omicron were not at the party but present at the same restaurant that evening. Not looking good re transmissibility. reuters.com/world/europe/o…
