The politics of the doorstep : female survival strategies and the legacy of the miners’ strike 1984–85.

This paper considers the legacy of continuing activism of women in the North East of England who organized in support of the 1984-85 miners' strike. It refers to the traditional responsibility of women in mining localities for the maintenance of neighbourhood and kin relations and using the example of a key activist in one ex-mining village, it argues that the values associated with 'mining community' remain relevant as a reference point for a self-conscious, politicized reshaping of local relationships in post-industrial conditions. The material basis for this self-conscious approach has shifted from the masculine sphere of mining work and its associated community institutions to the feminized sphere of location and neighbourhood

The application of parameter estimation to flight measurements to obtain lateral-directional stability derivatives of an augmented jet-flap STOL airplane

Flight experiments with an augmented jet flap STOL aircraft provided data from which the lateral directional stability and control derivatives were calculated by applying a linear regression parameter estimation procedure. The tests, which were conducted with the jet flaps set at a 65 deg deflection, covered a large range of angles of attack and engine power settings. The effect of changing the angle of the jet thrust vector was also investigated. Test results are compared with stability derivatives that had been predicted. The roll damping derived from the tests was significantly larger than had been predicted, whereas the other derivatives were generally in agreement with the predictions. Results obtained using a maximum likelihood estimation procedure are compared with those from the linear regression solutions

Inclusion of non-spherical components of the Pauli blocking operator in (p,p') reactions

We present the first calculations of proton elastic and inelastic scattering in which the Pauli blocking operator contains the leading non-spherical components as well as the usual spherical (angle-averaged) part. We develop a formalism for including the contributions to the effective nucleon-nucleon interaction from the resulting new G-matrix elements that extend the usual two-nucleon spin structure and may not conserve angular momentum. We explore the consequences of parity conservation, time reversal invariance, and nucleon-nucleon antisymmetrization for the new effective interaction. Changes to the calculated cross section and spin observables are small in the energy range from 100 to 200 MeV.Comment: 24 pages, 4 figures, to be published in Physical Review

Gas of self-avoiding loops on the brickwork lattice

An exact calculation of the phase diagram for a loop gas model on the brickwork lattice is presented. The model includes a bending energy. In the dense limit, where all the lattice sites are occupied, a phase transition occuring at an asymmetric Lifshitz tricritical point is observed as the temperature associated with the bending energy is varied. Various critical exponents are calculated. At lower densities, two lines of transitions (in the Ising universality class) are observed, terminated by a tricritical point, where there is a change in the modulation of the correlation function. To each tricritical point an associated disorder line is found.Comment: 19 pages, 6 figures. to appear in J. Phys. A : Math. & Ge

N-SAP and G-SAP neutron and gamma ray albedo model scatter shield analysis program

Computer program calculates neutron or gamma ray first order scattering from a plane or cylindrical surface to a detector point. The SAP Codes, G-SAP and N-SAP, constitute a multiple scatter albedo model shield analysis

Quark Model Calculations Of Symmetry Breaking in Parton Distributions

Using a quark model, we calculate symmetry breaking effects in the valence quark distributions of the nucleon. In particular, we examine the breaking of the quark model SU(4) symmetry by color magnetic effects, and find that color magnetism provides an explanation for deviation of the ratio $d_V(x)/u_V(x)$ from $1/2$. Additionally, we calculate the effect of charge symmetry breaking in the valence quark distributions of the proton and neutron and find, in contrast to other authors, that the effect is too small to be seen experimentally.Comment: 6 Pages, 3 postscript figures compressed using uufile

NONPOINT SOURCE AND CARBON SEQUESTRATION CREDIT TRADING: WHAT CAN THE TWO LEARN FROM EACH OTHER?

Emission trading programs have been discussed with respect to achieving water quality objectives and future caps on carbon emissions. A significant part of this literature explores the institutional and technical design issues associated with trades involving nonpoint effluent sources and carbon sequestration. This paper explores conceptual linkages between the nonpoint and carbon sequestration programs and identifies potential areas where cross fertilization can benefit research and policy design of trading programs for environmental protection.Environmental Economics and Policy, Resource /Energy Economics and Policy,
