‘Somewhere on the border of credibility’: the cultural construction and contestation of 'the border' in white South African society
South Africa’s Border War had profound implications for the social and political organisation of white society. Indeed, maintaining the credibility of South Africa’s presence in Namibia and the prosecution of the Border War was an important political project for the National Party (NP) government. The discourse of ‘the border’ became a powerful cultural sign in white society and underpinned a mythology that sustained and intensified South Africa’s militarisation. As a cultural mythology, ‘the border’ was not a complete fabrication of reality (there was indeed a war conducted on and close to the Namibian border), but white society attached political and social meanings to ‘the border’ that appeared to be ‘common sense’ and self-evident and yet were partial and contingent on the existence of a number of socially constructed discourses. It seemed, however, self-evident to the majority of white people that the border between Namibia and Angola had to be militarily defended if the Republic and all that was familiar were to survive. It is, therefore, unsurprising that dissent or criticism of the Border War emanating from within the community was met with rhetorical vitriol from NP and military leaders and punitive legal sanctions. This chapter will focus on the cultural construction of ‘the border’ and its contestation by a small group of white men who refused to serve as conscripts and their supporters in the End Conscription Campaign (ECC). The analysis reveals that gender norms were central to the operation of ‘the border’ as a cultural sign in white society and the most effective means for critiquing ‘the border’ were also gendered. Changing political and military circumstances, the realities of the effects (both psychological and physical) on white men returning from ‘the border’ and the discursive spaces opened by anti-conscription activists in South Africa, all challenged the credibility of the Border War and helped to hasten the end of the conflict in 1988
FTC vs. Toysmart
Last summer, Toysmart agreed to a settlement with the Federal Trade Commission concerning use of its customer information database. Under the terms of the settlement, the defunct Internet toy retailer was permitted to sell customer information without either providing its former customers notice or giving them an opportunity to block the sale or use of their personal information. This issue ignited a privacy-rights maelstrom, but ended anti-climatically for Toysmart; in January, Buena Vista Internet Group, a Disney subsidiary and 60% majority shareholder of Toysmart, agreed to compensate the company\u27s creditors $50,000 for the privilege of destroying the database. U.S. Bankruptcy Court Judge Carol Kenner approved this plan, subject to the limitation that Toysmart attorneys must retain the list and destroy it (rather than physically transfer it to Buena Vista) when all creditor claims are satisfied
Sutured Floer homology, sutured TQFT and non-commutative QFT
We define a "sutured topological quantum field theory", motivated by the
study of sutured Floer homology of product 3-manifolds, and contact elements.
We study a rich algebraic structure of suture elements in sutured TQFT, showing
that it corresponds to contact elements in sutured Floer homology. We use this
approach to make computations of contact elements in sutured Floer homology
over of sutured manifolds where is
finite. This generalises previous results of the author over
coefficients. Our approach elaborates upon the quantum field theoretic aspects
of sutured Floer homology, building a non-commutative Fock space, together with
a bilinear form deriving from a certain combinatorial partial order; we show
that the sutured TQFT of discs is isomorphic to this Fock space.Comment: v.2: 49 pages, 13 figures. Improved and expanded exposition, some

On Three-Dimensional Space Groups
An entirely new and independent enumeration of the crystallographic space
groups is given, based on obtaining the groups as fibrations over the plane
crystallographic groups, when this is possible. For the 35 ``irreducible''
groups for which it is not, an independent method is used that has the
advantage of elucidating their subgroup relationships. Each space group is
given a short ``fibrifold name'' which, much like the orbifold names for
two-dimensional groups, while being only specified up to isotopy, contains
enough information to allow the construction of the group from the name.Comment: 26 pages, 8 figure
Flux of water vapor in the terrestrial stratosphere and in the Martian atmosphere
A summary of the terrestrial satellite data is presented. The observations indicate that at equatorial latitudes, relatively dry air is introduced at the tropopause and carried to the upper stratosphere. At that altitude, any methane present in the ascending air mass is oxidized photochemically into water vapor. This vapor is eventually transported to high latitudes, where it is carried to the lower stratosphere by the descending leg of the diabatic circulation. The Pressure Modulator Infrared Radiometer instrument aboard the Mars Observer should provide a comparable picture of vapor transport in the martian atmosphere
Seed Yield Prediction Models of Four Common Moist-Soil Plant Species in Texas
Seed production by moist-soil plant species often varies within and among managed wetlands and on larger landscapes. Quantifying seed production of moist-soil plants can be used to evaluate wetland management strategies and estimate wetland energetic carrying capacity, specifically for waterfowl. In the past, direct estimation techniques were used, but due to excessive personnel and time costs, other indirect methods have been developed. Because indirect seed yield models do not exist for moist-soil plant species in east-central or coastal Texas, we developed direct and indirect methods to model seed production on regional managed wetlands. In September 2004 and 2005, we collected Echinochloa crusgalli (barnyard grass), E. walterii (wild millet), E. colona (jungle rice), and Oryza sativa (cultivated rice) for phytomorphological measurements and seed yield modeling. Initial simple linear and point of origin regression analyses demonstrate strong relationships (P \u3c 0.001) among phytomorphological and dot grid methods in predicting seed production for all four species. These models should help regional wetland managers evaluate moist-soil management success and create models for seed production for other moist-soil plants in this region
Radio Observations of the Hubble Deep Field South region: I. Survey Description and Initial Results
This paper is the first of a series describing the results of the Australia
Telescope Hubble Deep Field South (ATHDFS) radio survey. The survey was
conducted at four wavelengths - 20, 11, 6, and 3 cm, over a 4-year period, and
achieves an rms sensitivity of about 10 microJy at each wavelength. We describe
the observations and data reduction processes, and present data on radio
sources close to the centre of the HDF-S. We discuss in detail the properties
of a subset of these sources. The sources include both starburst galaxies and
galaxies powered by an active galactic nucleus, and range in redshift from 0.1
to 2.2. Some of them are characterised by unusually high radio-to-optical
luminosities, presumably caused by dust extinction.Comment: Accepted by AJ. 32 pages, 4 tables, 3 figures. PDF with

Dynamical state reduction in an EPR experiment
A model is developed to describe state reduction in an EPR experiment as a
continuous, relativistically-invariant, dynamical process. The system under
consideration consists of two entangled isospin particles each of which undergo
isospin measurements at spacelike separated locations. The equations of motion
take the form of stochastic differential equations. These equations are solved
explicitly in terms of random variables with a priori known probability
distribution in the physical probability measure. In the course of solving
these equations a correspondence is made between the state reduction process
and the problem of classical nonlinear filtering. It is shown that the solution
is covariant, violates Bell inequalities, and does not permit superluminal
signaling. It is demonstrated that the model is not governed by the Free Will
Theorem and it is argued that the claims of Conway and Kochen, that there can
be no relativistic theory providing a mechanism for state reduction, are false.Comment: 19 pages, 3 figure
Small Aircraft Transportation System, Higher Volume Operations Concept: Off-Nominal Operations
This document expands the Small Aircraft Transportation System, (SATS) Higher Volume Operations (HVO) concept to include off-nominal conditions. The general philosophy underlying the HVO concept is the establishment of a newly defined area of flight operations called a Self-Controlled Area (SCA). During periods of poor weather, a block of airspace would be established around designated non-towered, non-radar airports. Aircraft flying enroute to a SATS airport would be on a standard instrument flight rules flight clearance with Air Traffic Control providing separation services. Within the SCA, pilots would take responsibility for separation assurance between their aircraft and other similarly equipped aircraft. Previous work developed the procedures for normal HVO operations. This document provides details for off-nominal and emergency procedures for situations that could be expected to occur in a future SCA
