Obviously that’s nonsense, but just for the record in the past two weeks in Munich I’ve seen plenty of campaign posters for:

CSU (establishment right)
FDP (economic-liberal right)
Bayern Partei (regional-separatist right)
FW (localist right)
Γ–DP (environmentalist right)
AFD (far right)

The Conservative government also changed the electoral system for mayoral and PCC elections (largely to boost their chances in London) without a referendum. I can’t remember if it was in their manifesto, though.

The authors of this one are two of the top names in forensics in the UK and Ireland, so I’m sure it’s very good. I was just tickled by the title!

If the title of this book is to be believed, forensics must be easier to learn than I’d thought.

Your regular reminder that the UK is in fact a high trust society and anyone who implies it isn’t is either selling you a pup or has bought one.

Having once been shot with an air rifle by an oik in Goole (where my wife had to live briefly for work), I'm afraid none of those are my first choice of name for that part of the world!

Which of the two previous arbitrary administrative units do you feel particularly attached to?

Although to be able to get a sample of 1,000 people for Rutland, they’d have to have got 1 in every 40 people in the county to fill in the survey.

Given Humberside is 62 years old, surely it must be losing some of its sting by now?

If you spend any time in Cornwall or the Lake District, you’ll find that many, many people have moved there from elsewhere in England. But despite being incomers, they often feel attached to the area they’ve chosen.

Personally, I think all permanent residents should be able to vote in UK elections (particularly in local elections). I have no objection to Commonwealth nationals being able to vote in the UK, but I don't think the system can be justified on the basis of reciprocity that doesn't really exist.

03.03.2026 13:47 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

I'm aware of the origins, but your original post said we should think of these voters as "reciprocal citizen voters". But, as you say, very few Commonwealth countries now allow British residents to vote on that basis, so I don't think the system can *now* be described as based on reciprocity.

…

Were any of those systems reciprocal? i.e. in how many Commonwealth countries are British residents able to vote by virtue of their British/Commonwealth citizenship, or have been previously?

We, the Editor and Publishers of Journal of Criminal Justice Education, have retracted the following book review:

Kresnanda Annas, G. (2025). Organising White-Collar and Corporate Crimes: By Nicholas Lord and Michael Levi, New York: Routledge, Published 2025, 218 p., 19 B/W Illustrations, Β£35.99 (eBook), ISBN: 9781315100227. Journal of Criminal Justice Education, 30 April 2025, DOI: 10.1080/10511253.2025.2500310.

Following publication, a third party raised concerns regarding the integrity of the review. Upon investigation and following correspondence with the author, the Journal and Publisher confirm that this book review contains such extensive inaccuracies that it neither describes nor evaluates the book it claims to review.

We have been informed in our decision-making by our own publicly available editorial policies and COPE guidelines.

The retracted book review will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as β€˜Retracted’.

Well this looks like a pretty big editorial failure: a book review in the Journal of Criminal Justice Education retracted because it β€œcontains such extensive inaccuracies that it neither describes nor evaluates the book it claims to review”.

Mannheim Centre for Criminology | Event about police and policing in London This afternoon event draws together new research about police and policing in London, and reflects on whether intervening efforts to strengthen public trust have delivered.

There are still places left for the upcoming LSE/UCL event 'Police and People in London - What's changed in 40 years'. Afternoon of the 6th March at LSE. Come along - it'll be fun!

One day when I am chairing a panel, I will be brave enough to do what I have always wanted to do: start the Q&A by saying β€œand as a reminder, a question is a single sentence ending with a question mark, and which is relevant to the presentations.”

Students don’t have majors or minors in the UK, and unis don’t have boards of directors. The problem is caused by successive governments having continually set the funding given to unis to teach undergraduates below the cost of delivering that teaching.

That’s definitely true. Although every additional intermediate object introduces a chance of then referring to the wrong object later on in the code, which is something I see quite a lot in student assignments. And itβ€˜s especially dangerous when the later code runs, but gives the wrong answer!

(But since all my code starts with `pacman::p_load(some, other, packages, then, tidyverse)`, I only actually use `dplyr::` in package development)

Thinking as someone who teaches R to first year social science undergrads, I don’t think the value of the shortcut (of `d[,1]` returning a vector) is anywhere near worth the confusion it can cause vs `d[,1:2]`.

Although I’d only ever teach (and indeed use) `dplyr::select(col_name)` in any case!

20.02.2026 17:28 πŸ‘ 4 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

I find that fascinating, because to me a two-dimensional data structure remaining so when it happens (perhaps temporarily) to only have one column is obviously the logical behaviour. But apparently to others it’s the exact opposite!

20.02.2026 16:20 πŸ‘ 15 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

Although basing code on `d[,1]` being a vector just comes back to the β€˜at what cost?’ question, doesn’t it?

It did, and it was wonderful. As a Warwick undergrad I spent plenty of very happy time there.

Unfortunately the branch of Blackwells at the University of Nottingham has also just closed (although it wasn’t a patch on other uni bookshops in any case).

Cambridge is an hour on the train from Europe’s largest economic hub, and 40 minutes from an airport with 200+ flights a day, so wouldn’t say it’s exactly badly connected to economic opportunities.
