What a difference a colon makes (to academic citations)

July 22nd, 2016

ColonFollowing our recent report on the (report of the) finding that Short Paper Titles Tend to Have a Longer Reach (Improbable Research, June 16th 2016) we now inform about (research about) another possible method that academic authors might use to lever increased attention for their paper – with the disarmingly simple trick of adding a colon   :   somewhere in the title. See: ‘What a difference a colon makes: How superficial factors influence subsequent citation’ in: Scientometrics, March 2014, Volume 98, Issue 3, pp 1601-1615, by Maarten van Wesel, Sally Wyatt, and Jeroen ten Haaf.

Notes:
[1] The paper, which notably has a colon in its own title, has (at the time of writing) been cited 12 times.
[2] This format is currently not in vogue :—
[3] Colonic recommendations from the late Professor Larry Trask,
(as maintained by the Department of Informatics, University of Sussex).

Counting Things that Could Exist (philosophically)

July 21st, 2016

Prof-RosefeldProfessor Tobias Rosefeldt, of the Humboldt-Universität zu Berlin, Germany, counts things that could exist – in particular, he specifically does so in a new paper for The Philosophical Quarterly.

“Consider a tailor who works for a company that sells business suits as well as hipster suits. She has two business trousers and two business jackets in front of her and wonders in which combinations she should arrange them and whether she should dye the resulting suits pinkish in order to produce hipster suits or not. She asks herself the following question: ‘How many possible suits could I make by combining and dying the two jackets and the two trousers?’ “

Note that the imagined suits in the imagined example don’t actually exist, nevertheless, is it possible to ‘count’ them? The author bears in mind previous work on imaginary suit-counting, particularly the writings of Timothy Williamson ((1998). ‘Bare Possibilia’, in Erkenntnis, 48, 257–73.)

“Williamson assumes that a suit is constituted by a jacket and a pair of trousers that are originally hung together and that at most one possible suit can be made of a given jacket and a pair of trousers. He then shows that, given two jackets J1 and J2 and two pairs of trousers T1 and T2, there are four possible suits that could be made from J1, J2, T1 and T2, although it is impossible that there are ever more than two suits that are made from the set.”

The professor comes to a number of conclusions regarding such possibilia, arguing that (amongst other things) such cases –

“[…] should be understood as cases of quantification not over individual possible objects but rather over kinds of objects, some of which do not actually have instances.”

See: ‘Counting Things that Could Exist’ preprint in: The Philosophical Quarterly, May 16, 2016.

BONUS free thought experiment. Based on the author’s example regarding the numerical possibilia of  ‘Tomato Salads’, discuss how many could exist. [resauces]

Investigator Terry Sarnoff writes: “My nomination for your Colorful Names of Bolus Material contest is Superflab.”

Prior to receiving this note from investigator Sarnoff, we were not aware that we have colorful Names of Bolus Material contest. Here is a detail from a promotional flyer for Superflab, sent, along with that note, by investigator Sarnoff:
