Notes on Money, Credit, and Open Market Operations

These are some notes on a project I am working on as an extension of Williamson (2005b). The basic idea is to explore the implications of market segmentation, where the key novelty involves goods market segmentation and the proximity of connected households to particular goods markets. A connected household is on the receiving end of central bank actions, while an unconnected household is not. ...

On exponential domination and graph operations

An exponential dominating set of graph $G = (V,E )$ is a subset $Ssubseteq V(G)$ such that $sum_{uin S}(1/2)^{overline{d}{(u,v)-1}}geq 1$ for every vertex $v$ in $V(G)-S$, where $overline{d}(u,v)$ is the distance between vertices $u in S$ and $v  in V(G)-S$ in the graph $G -(S-{u})$. The exponential domination number, $gamma_{e}(G)$, is the smallest cardinality of an exponential dominating set....

Notes on Early Acheulian Stone Tools: Constitutive Operations and Analogies of the Soul

Early Acheulian bifaces appear to be characterized by seven basic operations. After a brief description of each operation, I propose how the pattern of that operation had the capacity to serve as an analogue for a concept of the soul that could be expressed both in self-concept (selfobject) and interpersonal relations (object relations). 1. A 'core' is flaked and the flake is trimmed, in turn, ...
