Characterization of preclones by matrix collections

Preclones are described as the closed classes of the Galois connection induced by a preservation relation between operations and matrix collections. The Galois closed classes of matrix collections are also described by explicit closure conditions.Comment: 11 page

I, Daniel Blake (2016): vulnerability, care and citizenship in austerity politics

This article offers a reading of Ken Loach’s 2016 film I, Daniel Blake, a fictionalised account of experiences of the UK welfare system in conditions of austerity. We consider, firstly, the significant challenge the film poses to dominant figurations of welfare recipients under austerity, through a focus on vulnerability to state processes. We follow with a reading of some of the film’s interventions in relation to reciprocity, drawing on the important trajectories of care, community and resistance that the film renders visible through the collective stories of the major characters. Finally, we conclude with reflections on citizenship, subject narratives and alternative imaginaries of ‘deservingness’. Our article offers an ‘against the grain’ reading (hooks, 1996; Wearing, 2013) of the film, highlighting some of the radical possibilities of the more minor moments, character arcs and subject positionalities within the film’s central narrative of Daniel’s experiences in the shadow of the steadily crumbling welfare state

Teaching to resistance and refusal: feminist pedagogical engagements in the UK Higher Education classroom

Critical feminist pedagogies have sought to emphasise the productive capacity of emotion in the classroom—from joy and curiosity to anger, discomfort, and guilt—alongside positioning refusal and resistance as necessary aspects of transformative learning and social justice. In this article, we offer speculative reflections on moments of classroom resistance and refusal within the limits of the broader institutional life of UK Higher Education (HE). Using an anecdotal method, we discuss the complexity of defining, knowing and assessing the meaning—let alone the productivity—of student resistance and refusal. Our reflections point towards the limiting effects of institutional practices on effective and inclusive teaching in the increasingly precarious UK HE context

On the homomorphism order of labeled posets

Partially ordered sets labeled with k labels (k-posets) and their homomorphisms are examined. We give a representation of directed graphs by k-posets; this provides a new proof of the universality of the homomorphism order of k-posets. This universal order is a distributive lattice. We investigate some other properties, namely the infinite distributivity, the computation of infinite suprema and infima, and the complexity of certain decision problems involving the homomorphism order of k-posets. Sublattices are also examined.Comment: 14 page

Pedagogies of inclusion: a critical exploration of small-group teaching practice in higher education

This paper provides a critical examination of inclusion as a pedagogic principle through a practice-based interrogation of contemporary ‘good practice’ strategies for encouraging inclusion in small-group teaching. It reflects on our experiences of delivering four classroom exercises that are frequently proposed as strategies for increasing inclusion, and borrows insight from critical intersectional feminist pedagogy to interrogate normative discourses of inclusion in HE. We argue that both the terms of inclusion, and the assumption that (verbal) participation is itself a measure of improving inclusion in classroom spaces, require interrogation. This article thus responds to the proliferation of inclusion discourses in contemporary UK HE, by identifying some of the potential pitfalls of measuring inclusion through the limited scope of participatio

Individual identification of Black-throated Divers (Gavia arctica)

The potential to identify individual Black-throated Divers (Gavia arctica) on the basis of breeding plumage features was explored using 278 photos, including two paired birds followed during the years 2007-2015 at a specific breeding location. Observations were focused on: 1) white lines on the sides of neck, 2) mantle having rows of sharply contrasting white squares, and 3) small white spots on lesser andmedian coverts. In photos, the number ofwhite lines on the sides of neck varied from four to seven (mean = 5.0, n = 278), and the second line from the head was the highest in 92.1% of the photos. The number of " white square" rows on the mantle varied from 11 to 14 and the small white spots on coverts from 27 to 67. Identification of individual Black-throated Divers was potentially easiest if the plumage had some special patterns (19.4% of birds, n = 278). Plumage remained the same in the followed pair between years, as was also shown by the discriminant analysis, since the followed pair was correctly classified by sex but not by sides showing that sides are similar. To estimate whether it is possible to separate these two birds from other birds, a second discriminant analysis was accomplished. Thus, 125 other birds were added to analysis as a third group together with the followed pair (female andmale, nine years and n = 18 per sex). The linear discriminant analysis yielded a classification rate of 70.8% in original analysis and 69.6% based on the leave-one-out analysis (n = 161). These analyses were based on the relative height of the neck lines, their average relative height and standard deviation. When the number ofwhite spotswere added to this discriminant analysis, a correct classification rate of 77.4% in original analysis and 75.7% in the leave-one-out analysis was obtained (n = 115). These following nesting pairs during their breeding seasons in different years. Presumed female andmaleBlack-throatedDiver could be distinguished based on the shape of the forehead.Peer reviewe

Clones with finitely many relative R-classes

For each clone C on a set A there is an associated equivalence relation analogous to Green's R-relation, which relates two operations on A iff each one is a substitution instance of the other using operations from C. We study the clones for which there are only finitely many relative R-classes.Comment: 41 pages; proofs improved, examples adde
