Polanski's excuse for not having voted on the "Zionism is Racism" motion appears to have been that he had to leave conference to go campaign in Holborn & St Pancras. But the Green Party explicitly offered an option allowing members to register to vote online. He could have voted from London.

CONFERENCE registration
All paid-up Green Party members are eligible to attend Conference and vote.

Book for one day, two days, or all three.
Attend in person (voting rights and access to all sessions) or online (voting rights, access to pre-Conference workshops and plenaries).
Choose the fee level which is right for you: Standard or Lower Income (fees are set out below).
Book before 1 September to take advantage of the early bird pricing.
Registrations will close at midnight on 25 September.

This article, published in November 2023, is still the best item I’ve read on its topic. Its paywall is temporarily down, and it should be absolutely mandatory reading for anyone even trying to grasp the conflict in a rational manner. ideas.tikvah.org/mosaic/essay...

Ecstasy and Amnesia in the Gaza Strip

Three catastrophes, all marked by euphoria at the start and denial at the end, have shaped the Palestinian predicament. Has the fourth arrived, and is the same dynamic playing out?

In all my years in the profession I never received emails out of the blue from people asking me to engage in a phone or video chat about their PhD proposals. I’ve received two in recent weeks. Is this a thing? (These don’t even claim to be potential applicants to UCD.)

My current thinking on where the Israeli polls and possible government formation outcomes stand. A lot of you won’t like this, but I’m just the messenger! And there is still time for (likely small but potentially significant) shifts before voting. fruitsandvotes.wordpress.com/2026/09/28/i...

Israel campaign with a month to go

There continues to be little evidence that either bloc can form a majority coalition, and the parliamentary math needed to allow the opposition to form a minority government with the support of Ra&…

Perhaps the Chief Rabbi understands the threats Jews face better than Miliband does. “Asked about Jews who will feel less safe in synagogue over Rosh Hashanah this weekend, Miliband, who is Jewish, responds: “I don’t go to synagogue.”” He doesn’t care. www.timesofisrael.com/liveblog_ent...

UK’s Miliband calls Israeli response to sanctions ‘damaging,’ rejects chief rabbi’s claim that British Jews have been put in danger

Legislative term limits are a terrible institutional reform that no jurisdiction should ever enact. We have mountains of data published in dozens if not hundreds of studies about what term limits have done where they've been enacted and there's not a single desirable outcome reported in any of them.

What’s a thing from your area of expertise (or special interest) that you think it would behoove everyone else to know?

I think this paper in part reproduces a measure of "intra-party unequal representation" found in "A unified approach to measuring unequal representation" doi.org/10.1007/s111... which very unfortunately is not cited

A unified approach to measuring unequal representation - Public Choice

The concept of unequal representation is commonly understood through the lenses of disproportionality and malapportionment, pertaining to inter-party and inter-district aspects, respectively. Popular indices used to measure such features are analyzed separately despite being mathematically identical. District-level wasted votes are not measured in terms of unequal representation, even though they can be conceptualized as intra-district unequal representation. A new component, intra-party unequal representation, which measures unequal representation across districts for voters who support each party, has not been considered to contribute to unequal representation. We propose a unified approach for measuring these components—disproportionality, malapportionment, wasted votes, and intra-party unequal representation—by using $${\alpha }$$ α -divergence. We show mathematically that the total of disproportionality and intra-party unequal representation equals that of malapportionment and wasted votes. We apply this approach to the Japanese political system and demonstrate the role of intra-party unequal representation in sustaining disproportionality in favor of the Liberal Democratic Party.

Tortie. You can see that she has three paws with the typical tortoiseshell coloration and then seems to wear a black stocking on the other. That’s something I never noticed in the six years during which I was feeding her outside. She’s also in her very typical splayed front legs posture.

It’s Tisha B’Av. I wrote the linked post two years ago but the themes persist. We get the absurd scenes of the police of the Jewish state arresting Jews for praying on the site of the Jewish temples, the destruction of which Jews mourn today. fruitsandvotes.wordpress.com/2025/08/03/t...

Tisha b’Av 5784 and the Temple Mount

In the question of whether Jews can visit the Temple Mount, we have a controversy that is significant within the orthodox Jewish world and within Israeli politics, let alone the controversy with re…

🗳️ Electoral Reform Alert 🗳️ Yesterday, the Italian Lower House approved a new electoral reform, now headed to the Senate. This would be the fifth major reform of the electoral system in Italy since 1993, and it could bring an even more radical right-wing party into the next government coalition. (1)
