In Conversation with Sophie Woodward and Ian Cook – Material Methods 4: Political Lego
No full textThis is the fourth episode of an NCRM “in conversation” series that focuses upon the emerging field of material methods. In this video, Sophie Woodward is in conversation with Ian Cook, who introduces political Lego as a method for critically engaging with consumption and follow-the-thing methods.
Ian is a cultural geographer and situates political Lego within geography. He explores how political Lego is a material method, with an emphasis upon the potentials of creative practices and ‘play’ for engaging with politics. This video is of interest for anyone wanting to engage with material and creative methods

Trading Time and Space in Catalytic Branching Programs
No full textAn m-catalytic branching program (Girard, Koucký, McKenzie 2015) is a set of m distinct branching programs for f which are permitted to share internal (i.e. non-source non-sink) nodes. While originally introduced as a non-uniform analogue to catalytic space, this also gives a natural notion of amortized non-uniform space complexity for f, namely the smallest value |G|/m for an m-catalytic branching program G for f (Potechin 2017).
Potechin (2017) showed that every function f has amortized size O(n), witnessed by an m-catalytic branching program where m = 2^(2ⁿ-1). We recreate this result by defining a catalytic algorithm for evaluating polynomials using a large amount of space but O(n) time. This allows us to balance this with previously known algorithms which are efficient with respect to space at the cost of time (Cook, Mertz 2020, 2021). We show that for any ε ≥ 2n^(-1), every function f has an m-catalytic branching program of size O_ε(mn), where m = 2^(2^(ε n)). We similarly recreate an improved result due to Robere and Zuiddam (2021), and show that for d ≤ n and ε ≥ 2d^(-1), the same result holds for m = 2^binom(n, ≤ ε d) as long as f is a degree-d polynomial over ₂. We also show that for certain classes of functions, m can be reduced to 2^(poly n) while still maintaining linear or quasi-linear amortized size.
In the other direction, we bound the necessary length, and by extension the amortized size, of any permutation branching program for an arbitrary function between 3n and 4n-4
Navinaxonopsis Cook 1967
No full textSubgenus Navinaxonopsis Cook, 1967 Axonopsis (Navinaxonopsis): Cook, 1974 a, p. 334, figs. 1393, 1397, 1398, 1400, 1406. Diagnosis of adults. Character states of genus Brachypodopsis. Fourth leg of males with tibia slender proximally but greatly expanded distally, and with tarsus curved. Type species. Axonopsis (Navinaxonopsis) abnormipes Cook. Species included. Brachypodopsis (N.) abnormipes (Cook) (India), B. (N.) persica (Pešić) (Iran, Turkey). Distribution. India and western Asia. Discussion. Cook (1974 a) considered Navinaxonopsis to be a subgenus of Axonopsis and Pešić (2004) followed that treatment. Here we propose to transfer the taxon as a subgenus to the genus Brachypodopsis. As in the case of Kalobrachypoda, the species of Navinaxonopsis appear to represent a divergent offshoot of the species complex typified by Brachypodopsis baumi Halik and the status of this taxon will also need to be reevaluated when the phylogeny of the genus Brachypodopsis is more completely known.Published as part of Smith, Ian M., Cook, David R. & Gerecke, Reinhard, 2015, Revision of the status of some genus-level water mite taxa in the families Pionidae Thor, 1900, Aturidae Thor, 1900, and Nudomideopsidae Smith, 1990 (Acari: Hydrachnidiae), pp. 111-156 in Zootaxa 3919 (1) on page 140, DOI: 10.11646/zootaxa.3919.1.6, http://zenodo.org/record/24458

A Visual Analysis of Meet … Captain Cook (2011) – a Modern Australian Picture Book
No full textThis article analyses how images and text have been used in the children’s picture book Meet … Captain Cook (2011) by using the Ideational, Interpersonal and Textual metafunctions developed by Clare Painter et al. (2013). The metafunctions operate simultaneously and are about something (ideational), enable communicative interaction with others (interpersonal), and make sense in relation to previous understandings (textual). An examination of the images and texts using this framework will facilitate an insight into how the author and illustrator of Meet … Captain Cook explore Cook and his legacy, notably his first encounter with the First Nations peoples of Australia, and how it contrasts with the historical record. The metafunctions developed by Painter reveal an often-precarious balancing of a long-standing and often uninterrogated respect for Cook and the colonial legacy of white possession and Indigenous dispossession
