English School “Teaching the English School at the undergraduate level”
No full textThis chapters offers an overview of the theoretical, methodological, and practical aspects of teaching the English School (ES) at the undergraduate level. Drawing on the author’s work at the University of St Andrews, as well as on the experience and the inputs of tutors and students, the chapter discusses, in a personal and reflexive style, the main tenets of the theory, the challenges associated to the teaching thereof, the utility of case-studies in lectures, and the learning outcomes. The main challenges identified are related to the theory’s perceived Eurocentrism, its analytical terminology, and the differences with other International Relations theories, in particular Realism and Constructivism. However, the learning outcomes also show that, through specific examples, case-studies, and tutorials and essay questions, the students understand how the ES, despite its limitations, can shed a helpful light on notions of order, history, morality, agency, and structure, appreciating its holism and eclecticism
Hirshfeld surface and fingerprint plot analysis of non-covalent interaction (NCI) in Cu<sup>II</sup> −based catecholase models
No full textUnderstanding of molecular packing is one of the favorable modes to study the mechanistic behavior of a supramolecular system. The present study aims in analyzing the molecular packing and supramolecular arrangement of Cu+2-catecholase system [C13H13BrCuN4O2 (System A) C14H17BrCuN4O3 (System B) and C20H36Cl2Cu2N4O11 ((System C)] with variable auxiliary groups. These systems are well studied for their reversible binding with oxygen and catalytic property towards oxidation of ortho-diphenol. The primary novelty of such study is elucidating the architecture of auxiliary part of the system whose influence is studied but not understood in terms of the molecular packing. The respective supramolecular arrangement of the Cu (II) systems having such auxiliary part is reported herein which illustrates the interaction efficacy with macromolecules like proteins. The respective non covalent interactions (NCI) of aforementioned three antiferromagnetic Cu (II) species are reported using Hirsfeld analyses which also helps in the correlation of structure–property interaction.</p
Introduction: Innovation and exile
No full textThe early modern period was an age marked by the forced migration and displacement of social groups and individuals around the world. Huguenots, conversos, Catholics, cavaliers, Jacobites, and French emigrés alike fled or were expelled from their homes and communities. Yet, exile is still usually considered only within the context of broader religious or political events by scholars working in sub-fields rather than as a phenomenon worthy of study in its own right. Foregrounding displacement as a major facet of early modern society and culture, this special issue explores the experience, perception, and poetics of exile from 1500 to 1800 through the prism of innovation. It encompasses displaced individuals and communities, as well as writings that treat the theme of exile, to consider how forced migration shaped the social, cultural, political, and intellectual contours of the era – and thus led to innovative practices and ideas
Congruences of maximum regular subsemigroups of variants of finite full transformation semigroups
No full textLet X be the full transformation monoid over a finite set X, and fix some a ∈ X of rank r. The variant aX has underlying set X , and operation f * g = fag. We study thecongruences of the subsemigroup P = Reg(aX) consisting of all regular elements of aX, and the lattice Cong(P) of all such congruences. Our main structure theorem ultimately decomposes Cong(P) as a specific subdirect product ofCong(r), and the full equivalence relation lattices of certaincombinatorial systems of subsets and partitions. We use thisto give an explicit classification of the congruences themselves,and we also give a formula for the height of the lattice
Schlieren texture and topography induced confinement in an organic exciton-polariton laser
No full textNon-linearities in organic exciton-polariton microcavities represent an attractive platform for quantum devices. However, progress in this area hinges on the development of material platforms for high-performance polariton lasing, scalable and sustainable fabrication, and ultimately strategies for electrical pumping. Here, we show how introducing Schlieren texturing and a rough intra-cavity topography in a liquid crystalline conjugated polymer enables strong in-plane confinement of polaritons and drastic enhancement of the lasing properties. In high-Q distributed Bragg reflector microcavities, polariton lasing was observed at unprecedented thresholds of 136 fJ per pulse. Morphology tuning also permitted polariton lasing in more lossy metallic microcavities while maintaining a competitive lasing threshold. The facile fabrication of these cavities will drastically reduce the complexity of integrating polariton lasers with other structures and the high conductivity of metallic mirrors may provide a route to electrical pumping
Eocene gastropods of the New Forest, UK
No full textGastropods expanded into niches vacated by both terrestrial and marine organisms following the end-Cretaceous mass extinction, to become one of the dominant mollusc groups of the Cenozoic. The Selsey Formation of Eocene age was deposited within a shallow marine embayment across the Hampshire Basin (southern England) and contains a particularly diverse gastropod assemblage, forming the surface geology across the northern part of the New Forest National Park. Here, I use closely related gastropod species alive in the seas today to offer insights into the lifestyles and habitats of extinct Eocene species. By integrating this with other geological evidence, including gastropod preservation and other associated fossils, I paint a picture of the climate and environment on the New Forest seafloor during the Eocene epoch

No full textCharge doping into spin minority states mediates doubling of T<sub>C</sub> in ferromagnetic CrGeTe<sub>3</sub>
No full textThe recent discovery of the persistence of long-range magnetic order when van der Waals magnets are thinned towards monolayers provides a tunable platform for engineering of novel magnetic structures and devices. Here, we study the evolution of the electronic structure of CrGeTe3 as a function of surface electron doping. From angle-resolved photoemission, we observe spectroscopic fingerprints that this electron doping drives a marked increase in TC, reaching values more than double that of the undoped material, in agreement with recent studies using electrostatic gating. Together with density functional theory calculations and Monte Carlo simulations, we show that, surprisingly, the increased TC is mediated by the population of spin-minority Cr t2g states, forming a half-metallic 2D electron gas. This promotes a novel variant of double exchange, and unlocks a significant influence of Ge – which was previously thought to be electronically inert in this system – in mediating Cr-Cr exchange
