On the formal neighborhood of a degenerate arc

We prove a result describing the structure of the formal neighborhoods of certain arcs in the arc space of an algebraic variety which are completely contained in the singular locus. In particular, we provide a precise formulation of the intuitive statement that constant arcs centered in the singular locus are the most singular points of the arc space.Comment: 10 pages; comments are welcom

Low-Fired Earthenwares in the African Diaspora: Problems and Prospects

Local earthenware associated with enslaved African populations in the Americas, variously called “Colono-Ware,” “Afro-CaribbeanWare.” “Yabbas,” and “Criollo ware,” has received considerable attention from researchers. What unifies this disparate group of ceramics is not method of manufacture, design and decoration, or even form and function but the association or potential association with African diaspora populations. The ceramics incorporate some skills and techniques possibly brought by African potters to the Americas, as well as skills reflecting European and Native American traditions, and local adaptations in form, function, and manufacture.Analogies linking African ceramic traditions to American industries have at times been employed uncritically and have relied on generalized characteristics to infer overly specific meanings. With particular reference to low-fired earthenwares from Jamaica, this paper examines the historical and cultural context of these ceramics and the methodological and theoretical problems faced in their interpretation

Aquinas on Persons, Psychological Subjects, and the Coherence of the Incarnation

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine

St. Thomas Aquinas's Concept of a Person

This article develops an argument in defense of the claim that Aquinas holds that there are some kinds of activities which can be performed only by persons. In particular, it is argued that Aquinas holds that only persons can engage in the activities proper to a rational nature, e.g., the activities of intellect and will. Next, the article turns to discuss two implications of this thesis concerning Aquinas’s concept of a person. First, the thesis can be used to resolve a prominent scholarly debate concerning Aquinas’s views on the possibility of human persons surviving their bodily deaths. Second, it also points to a problem with a leading interpretation of Aquinas’ account of the Christian doctrine of the Incarnation. Finally, the article concludes by discussing how a correct interpretation of Aquinas’s views on these matters is related to a broader scholarly debate concerning the history of the Western concept of a person

Persons, Souls, and Life After Death

Thomistic Hylomorphists claim that we human persons have rational or intellective souls which can continue to exist separately from our bodies after we die. Much of the recent scholarly discussion of Thomistic Hylomorphism has centered on this thesis and the question of whether human persons can survive death along with their souls or whether only their souls can survive in this separated, disembodied, post-mortem state. As a result, two rival versions of Thomistic Hyomorphism have been formulated: Survivalism and Corruptionism. This chapter makes a new contribution to the debate between Survivalists and Corruptionists by identifying a heretofore undiscussed problem for Corruptionist Thomistic Hylomorphism. In particular, it is argued that if Corruptionists were right that human persons cannot survive their deaths along with their souls, this would undermine the grounds on which all Thomistic Hylomorphists, including Corruptionists, rely to justify their belief that our souls can continue to exist after our deaths. Given this, it is argued that Thomistic Hylomorphists have grounds for thinking that our souls can continue to exist after our deaths only if they allow, as Survivalists do and Corruptionists do not, that we human persons can continue to exist after our deaths, with souls but no bodies

Recent Updates to the CFD General Notation System (CGNS)

The CFD General Notation System (CGNS) - a general, portable, and extensible standard for the storage and retrieval of computational fluid dynamics (CFD) analysis data has been in existence for more than a decade (Version 1.0 was released in May 1998). Both structured and unstructured CFD data are covered by the standard, and CGNS can be easily extended to cover any sort of data imaginable, while retaining backward compatibility with existing CGNS data files and software. Although originally designed for CFD, it is readily extendable to any field of computational analysis. In early 2011, CGNS Version 3.1 was released, which added significant capabilities. This paper describes these recent enhancements and highlights the continued usefulness of the CGNS methodology
