Intrinsic knotting and linking of complete graphs

We show that for every m in N, there exists an n in N such that every embedding of the complete graph K_n in R^3 contains a link of two components whose linking number is at least m. Furthermore, there exists an r in N such that every embedding of K_r in R^3 contains a knot Q with |a_2(Q)| > m-1, where a_2(Q) denotes the second coefficient of the Conway polynomial of Q.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol2/agt-2-17.abs.htm

The value of books : the fantastic flying books of Mr. Morris Lessmore and the social hieroglyphic of reading

The late eighteenth century witnessed the emergence of new technologies of subjectivity and of the literary. Most obviously, “the novel as a literary form appeared to embody and turn into an object the experience of life itself” (Park), and the novel genre came to both reflect and shape notions of interiority and subjectivity. In this same period, “A shift was taking place in the way people felt and thought about children and the accoutrements of childhood, including books and toys, were implicated in this change” (Lewis). In seeking to understand the relationships between media (e.g. books and toys), genres (e.g. novels and picture books), and modes of subjectivity, Marx’s influential theory of commodity fetishism, whereby “a definite social relation between men, that assumes, in their eyes, the fantastic form of a relation between things”, has served as a productive tool of analysis. The extent to which Marx’s account of commodity fetishism continues to be of use becomes clear when the corollaries between the late eighteenth-century emergence of novels and pictures books as technologies of subjectivity and the early twenty-first century emergence of e-readers and digital texts as technologies of subjectivity are considered. This paper considers the literary technology of Apple’s iPad (first launched in 2010) as a commodity fetish, and the circulation of “apps” as texts made available by and offered as justifications for, this fetish object. The iPad is both book and toy, but is never “only” either; it is arguably a new technology of subjectivity which incorporates but also destabilises categories of reading and playing such as those made familiar by earlier technologies of literature and the self. The particular focus of this paper is on the multimodal versions (app, film, and picture book) of The Fantastic Flying Books of Mr. Morris Lessmore, which are understood here as a narrativisation of commodity fetishism, subjectivity, and the act of reading itself

Pocohontas's baptism : Reformed theology and the paradox of desire

Seeking to elucidate certain elements of Reformed theology, the writer explores the conversion narrative concerning the baptism, in the early 17th century, of the Native American woman Pocahontas. She explains that in a letter detailing his anxieties about his relationship with Pocahontas, the English settler John Rolfe denies the desire of carnal affection while celebrating his longing to convert Pocahontas. She highlights this link between the desire for the flesh and the desire for the spirit, and she traces the ways in which these longings operate in Rolfe's letter and in the baptismal theology informing the conversion of Pocahontas. She suggests that an analysis of the desires of the convertor and of the connection between the feared yearning for the flesh and the sacred desire for the divine reveal important aspects of Reformed thought

The Vulnerable Child as Pedagogical Subject of Risk Management

This paper seeks to examine the ways in which the idea of the child as high vulnerable to risk is constituting new pedagogical subjects, ie, the teacher/caregiver as a professional risk-manager, and the child as a risk-management ‘case’. It does so by indicating how an expanded notion of the duty of care has reconstituted the child as a work-in-progress case rather than 'the concrete subject of [educational] intervention' (Castel, 1991: 288). It examines how the new teacher as a risk-conscious professional caregiver both needs and comes to acquire a new intimacy with the child not as a fleshly body but as a case of risk minimisation

Synthesis and Photocatalytic Performance of TiO2-CNT and Magnetized Fe3O4-TiO2-CNT Multifunctional Hybrids: A Pickering Emulsion Platform for Organic Degradation

The oil and textile industries produce billions of gallons of wastewater containing toxic, and sometimes carcinogenic or mutagenic, chemicals that often disperse throughout wastewater as suspended oil droplets. Photocatalytic degradation is a promising method for organic degradation, but needs to be improved. Tuning the photoactivity of a photocatalyst, enhancing the reactor design, and ensuring a facile method to remove the photocatalysts from the purified wastewater will help photocatalysis become a realistic option for use in advanced water treatment plants. Thus, this study set out to engineer an efficient and reusable method to degrade dispersed organic chemicals, by combining the photocatalytic properties of titania (TiO2), the electronic and hydrophobic properties of carbon nanotubes (CNTs), the magnetic abilities of iron oxide magnetite (Fe3O4), and the novel reactor design of Pickering emulsions. In this study, CNTs were hybridized with TiO2 and magnetized with Fe3O4 following a sol-gel method in order to form TiO2-CNTs and magnetic Fe3O4-TiO2-CNTs. The nanohybrids were used to stabilize Pickering emulsions, and preliminary dye degradation was demonstrated.Chemical EngineeringCivil, Architectural, and Environmental Engineerin

At the heart of the home : An animal reading of mikhail bulgakov's the heart of a dog

When we try and contemplate who it is that we think we are in the world history has an important role to play. It can alert us to what we have lost; can point up how we have come to think what we think; and can remind us that what we think now will, inevitably, change — will be succeeded by other models, also temporary, also trying to make meaning out of who it is that we think we are. In these terms, the history of the human is not simply a history of progress from a “bad” model of who we are (Aristotle’s sense of the human as special and separate from all animals; Aquinas’s sense of the human as the only center of the moral universe, for example) to a “good” one in which our relationship with and location in the natural world is more fully acknowledged. Rather, we should perhaps also view the place of our species as a shifting one in which processes of what could be termed humanning, unhumanning, and rehumanning are constantly taking place

Identity

I explore proposals for stating identity criteria in terms of ground. I also address considerations for and against taking identity and distinctness facts to be ungrounded
