Constructing English in New Zealand: A report on a decade of reform
In 1991, the newly elected National Government of New Zealand set in train a major reform of the New Zealand national curriculum and, a little later, a major reform of the New Zealand qualifications system. These reforms have had a major impact on the construction of English as a subject in New Zealand secondary schools, and the work and professional identity of teachers. This article uses as a basis for analysis a framework which posits four paradigms for subject English and proceeds to examine the current national English curriculum in New Zealand for its underlying discourses. In specific terms, it explores questions of partition and progression, and terminology. In respect of progression, it argues that the current curriculum has imposed a flawed model on teachers and students, in part because of its commitment to the assignment of decontextualised outcomes statements (‘achievement objects’) to staged levels of student development (levels). It also argues that much of the terminology used by the document has had a negative impact on metalinguistic classroom practice. Finally, while it views the national English curriculum as a discursively mixed bag, it notes an absence of critical discourses and a tendency, in recent qualifications reforms, to construct English teachers as technicians and the subject as skills-based
GERT simulation program for GERT network analysis
GERT Simulation Program simulates GERT networks to obtain statistics on specified nodes of the network. It performs sampling experiments to determine which branches of the network are taken and how long it takes to traverse a branch of the network
The Bacillus cereus GerN and GerT protein homologs have distinct roles in spore germination and outgrowth, respectively
The GerT protein of Bacillus cereus shares 74% amino acid identity with its homolog GerN. The latter is a Na+/H+-K+ 19 antiporter that is required for normal spore germination in inosine. The germination properties of single and double mutants of B. cereus ATCC10876 reveal that unlike GerN, which is required for all germination responses that involve the GerI germinant receptor, the GerT protein does not have a significant role in germination, although it is required for the residual GerI-mediated inosine germination response of a gerN mutant. In contrast, GerT has a significant role in outgrowth; gerT mutant spores do not outgrow efficiently under alkaline conditions, and outgrow more slowly than wild type in the presence of high NaCl concentrations. The GerT protein in B. cereus therefore contributes to the success of spore outgrowth from the germinated state during alkaline or Na+ stress

Transport coefficients and quantum fields
Various aspects of transport coefficients in quantum field theory are
reviewed. We describe recent progress in the calculation of transport
coefficients in hot gauge theories using Kubo formulas, paying attention to the
fulfillment of Ward identities. We comment on why the color conductivity in hot
QCD is much simpler to compute than the electrical conductivity. The
nonperturbative extraction of transport coefficients from lattice QCD
calculations is briefly discussed.Comment: 15 pages with 9 eps figures. Combined invited talk by G.A. and poster

GERT EXCLUSIVE-OR combining paths and loops of electrical networks
Program takes a network with multi-parameter branches and reduces it to a network having a single branch connecting source nodes to sink nodes. The program calculates probability, expected time, and variance in the time to go from each source node to each sink node of the GERT network
User Manual for GERT EXCLUSIVE-OR Program
This report describes the procedures for using digital computer programs for analyzing GERT networks which contain nodes of the EXCLUSIVE-OR type and branches which have both a probability and a time associated with them. The time associated with a branch can be a random variable. The program calculates the probability, the expected time and the variance in the time to go from each source node of the GERT network to each sink node. Programs have been written in FORTRAN II and FORTRAN IV and have been exercised on the IBM 1130, GE 225 and CDC 3400 computers. This report details the operating procedures for using these programs. Four examples are included to illustrate the important facets involved in using the programs. Special options included in the program are: (1) printout of all loops and paths associated with the network; and (2) deletion of loops that have a probability of occurrence less than a value specified by the user. The program described in this report has been submitted to COSMIC
Transport coefficients and the 2PI effective action in the large N limit
We discuss the computation of transport coefficients in large N_f QCD and the
O(N) model for massive particles. The calculation is organized using the 1/N
expansion of the 2PI effective action to next-to-leading order. For the gauge
theory, we verify gauge fixing independence and consistency with the Ward
identity. In the gauge theory, we find a nontrivial dependence on the fermion
mass.Comment: 10 pages, based on presentations at Strong and Electroweak Matter
