Groups with a given number of nonpower subgroups
It is well-known that no group has either exactly 1 or exactly 2 nonpower subgroups. In this paper, we obtain a classification of groups containing exactly 3 nonpower subgroups. Moreover, we show that there is a unique finite group with exactly 4 nonpower subgroups. Finally, we show that given any integer k greater than 4, there are infinitely many groups with exactly k nonpower subgroups
The Ainu in documentary films: promiscuous iconography and the absent image
Images showing how Ainu physical traits significantly differed from their neighbours in the Far East fuelled the widespread idea in the West that the Ainu had European ancestors. This triggered an exceptional interest in Ainu culture among the European as well as American audiences between the Meiji period and the outbreak of the “Chinese Incident” in 1937. It is in this period when the Ainu were featured in a number of moving images to be screened outside Hokkaido. The aim of this chapter is to assess the standardisation of Ainu iconography during this period and interrogate the role played by cinema in this process. To that end, the relevance of moving images in the early history of the representation of the Ainu people is assessed in relation to a complex process of visual codification that also involved painting, engraving and photography
The legacy
During the past year and more, the author have been receiving a steady flow of information – news articles, commentaries, leaflets, statements, official and unofficial, counter-statements – from the University of Cape Town (UCT) and beyond about the protest campaigns that have been taking place in universities across South Africa since March 2015. In this she have been indebted to a number of people from within the student movement, to legal scholar Jaco Barnard-Naudé, as well as more broadly to international scholars and writers with stories deeply entwined in South Africa such as Gillian Slovo and Drucilla Cornell, to the writing of Pumla Gobodo-Madikezela, in-depth analyst of the lasting traumas of the nation, and many more. For South Africa, the dream was of course, not just freedom, but reconciliation, the latter to be effected through the manifold pathways of truth. That was the challenge and the new dispensation intended to create a better world
Fire and blood: Walter Benjamin’s Paris commune
Walter Benjamin's 'Arcades Project' provides a counter-history of Paris in the 19th century – and offers a vivid portrait of the revolutionary chaos and bloody demise of the Paris Commune
To die one’s own death – thinking with Freud in a time of pandemic, livestreamed from London Freud Museum, 23 September 2020
It has been a hundred years since the tragic loss of Freud’s daughter, Sophie Halberstadt-Freud, to the Spanish flu shortly after the end of World War One. In this essay, delivered as the 47th Annual Vienna Freud Museum lecture, Jacqueline Rose argues that Freud’s historic moment – of grief, pandemic and war – had an even more decisive impact on his thinking than has previously been recognised. Freud’s writings on the death drive collide with, and are fuelled by, an increasingly urgent engagement with our innermost psychic and biological relationship to the past and, at the same time, with the cruelty and injustice of the world. Today, as we confront the darkness of the hour, psychoanalysis has never been more urgently needed. What can we still learn from Freud about how to live and how to die in our own troubled times

'Transitional Justice: Contending with the Past', Michael Newman. Cambridge: Polity, 2019, pp.204, ISBN 9781509521166, £15.99 (pbk)
Michael Newman, in his characteristically lucid and balanced new book, recognises that this explosion has been parodied in 2009 as a Transitional Justice (TJ) industry, composed of ‘teams of experts, consultants, standardized software packages or data management, and a set of assumptions regarding how “to do memory” and why memory matters.”
For his part, Newman provides a readable summary, introducing the debates, outlining the key ideas, and giving an overview of the vast literature, with reference to case studies including South Africa, Cambodia and Sierra Leone.
Newman tells us that his subtitle, “Contending with the Past”, was devised by Christine Bell, as the most appropriate description of TJ.
The book contains a wealth of information and clearly presented arguments and evaluations
Routledge handbook of biosecurity and invasive species
Book synopsis: This handbook provides a comprehensive overview of the assessment and management of potentially dangerous infectious diseases, quarantined pests, invasive (alien) species, living modified organisms and biological weapons, from a multitude of perspectives.
Issues of biosecurity have gained increasing attention over recent years but have often only been addressed from narrow disciplines and with a lack of integration of theoretical and practical approaches. The Routledge Handbook of Biosecurity and Invasive Species brings together both the natural sciences and the social sciences for a fully rounded perspective on biosecurity, shedding light on current national and international management frameworks with a mind to assessing possible future scenarios. With chapters focussing on a variety of ecosystems – including forests, islands, marine and coastal and agricultural land – as well as from the industrial scale to individual gardens, this handbook reviews the global state of invasions and vulnerabilities across a wide range of themes and critically analyses key threats and threatening activities, such as trade, travel, land development and climate change.
Identifying invasive species and management techniques from a regional to international scale, this book will be a key reference text for a wide range of students and academics in ecology, agriculture, geography, human and animal health and interdisciplinary environmental and security studies
Guidelines for direct action during the Twenty-First Century years of plague
This essay is an invitation to consider the question of direct action in the acts of protest that have dominated the public scene during the twenty-first century years of plague. It explores the role of aesthetic ideas that can guide realization-comparisons and the performance of acts in real-time. As such, it works from within an undercurrent of political philosophy originating between Europe, Africa and the Americas. Namely, utopianism. From Thomas More’s Utopia to Julio Cortázar Una utopía realizable. From Marx’s “new struggle in the press” to the combative acts of enslaved Africans in the Americas. From the (post-Kantian) ideals of the imagination to the prefigurative politics of Tricontinentalism, and the New Left that is being reinvented nowadays by art practices intersecting ethical and legal discourses as gallery space spills over into street space and now-time explodes the not-yet in real-time social struggle. This essay is structured into six sections containing six simple guidelines for direct action during the twenty-first century years of plague
