New Light On 'How Labour Governs': Rediscovered Political Writings By Vere Gordon Childe, Terry Irving

Terence H Irving, Dr (Terry)

This article uses four rediscovered political essays by Gordon Childe to revise certain accounts of his political thought in the period when he was writing 'How Labour Governs' (1923). It shows that he was not a syndicalist; that he would not be hostile 'to a real Labor government'; that he had not renounced working-class politics; but that he was concerned about the negative effects of Labor's obsession with capturing the state on working class solidarity.

Effects Of Surfaces On Dynamic Percolation, H. K. Janssen, B. Schaub, Beate Schmittmann

Beate Schmittmann

The general epidemic process, which is a stochastic multiparticle process belonging to the universality class of dynamic percolation, is studied in a semi-infinite geometry. Critical exponents characterizing the fractal properties are calculated to O(ε) (ε=6-d, where d is the spatial dimension) with use of renormalization-group techniques.

Modified Broyden’S Method For Accelerating Convergence In Self-Consistent Calculations, Duane D. Johnson

Duane D. Johnson

A modification to Broyden’s method for obtaining stable and computationally efficient convergence in self-consistent calculations is developed and discussed. The method incorporates the advantages of two schemes proposed by Srivastava and by Vanderbilt and Louie without any increase in complexity. Its improvement over their methods is discussed. The present method is compared with two other widely used convergence methods, simple mixing and Anderson’s method, for the case of the disordered binary alloy Ni0.35Fe0.65 on the verge of a magnetic instability and is shown to be much improved in stability and rate of convergence.

The Effect Of Solvent Type On The Infrared Spectrum Of Carbon Monoxide Adsorbed At Platinum Electrodes, Mark Anderson, Daniel Blackwood, Thomas Richmond, Stanley Pons

Mark R. Anderson

The infrared spectrum of CO adsorbed on a platinum electrode from several solvents was investigated. In N-methylformamide, acetonitrile, and 1,2-dichloroethane, the infrared band attributed to linearly bonded CO had experimental Stark tuning rates of 20 cm−1/V, 22 cm−1/V, and 19 cm−1/V, respectively. For each of these solvents, the potential dependence of the band position was found to be linear for the entire potential range investigated. When methanol was the solvent, the plot of the band position versus potential had three distinctly linear portions, each with a different value for the slope. The behavior is explained in terms of the ability …

The Behavior Of The Infrared Spectrum Of Carbon Monoxide Adsorbed At Platinum Electrodes From Non-Aqueous Solvents, Mark Anderson, Daniel Blackwood, Stanley Pons

Mark R. Anderson

Electrochemical oxidation of vanadium hexacarbonyl anion, V(Co)6 in aprotic solvents results in formation of the V(0) complex which decomposes to form CO in high concentrations next to the electrode surface. As a result, CO is more rapidly adsorbed on the surface than by conventional methods. Surface reflection infrared spectroscopy shows that the potential dependent frequency shift for the infrared active bands due to CO adsorbed on platinum is 19 cm−1/V in 1,2-dichloroethane and 22 cm−1/V in acetonitrile, which are considerably less than the 30 cm−1/V observed in aqueous systems.

Potential Energy Surfaces For The Reaction Si (Silicon) + H2o (Water), Shogo Sakai, Mark S. Gordon, Kenneth D. Jordan

Mark S. Gordon

The potential energy surfaces for the reactions of silicon atom (ID and 3P) with the water molecule were calculated by ab initio self-consistent field (SCF) methods. The transition states for the insertion of silicon atom into the D--H bond of water were also calculated by the multiconfigurational SCF method. It is found that the crossing point of the singlet and triplet surfaces along the insertion reaction paths is near the transition state for the triplet rearrangement from the Si:OH2 complex to HSiOH. The potential energy surfaces for the 1,2-hydrogen migration HSiOH- H2Si0 in the singlet and triplet states and the …

Measuring Interest In Mathematics, P Gardner, Siek Toon Khoo

Dr Siek Toon Khoo

This paper reports on the development of instruments for measuring secondary school student interests in mathematics. Interest in mathematics is regarded as having three components (topics, activities and motives), each with several dimensions. Nearly all instruments employed summated ratings (Likert) procedures, but one adopted an unusual procedure, based on Zuckerman's (1960) Affect Adjective Checklist. Six instruments were developed altogether: IMT (interest in various mathematical topics), ILA (interest in learning activities), MCI (mathematics related career inventory), NMI (nature of motives inventory), GIM (general interest in mathematics) and AAC (affect adjective checklist). The IMT instrument, containing seven scales, was developed to measure …

Secondary School Size, Operating Costs And Curriculum Structure, Phil Mckenzie

Dr Phillip McKenzie

Proponents of increases in average school size commonly employ two main arguments: bigger schools are less expensive to operate than small schools, and they are better able to meet students' educational needs through the provision of more extensive curricula. This paper examines these arguments in the case of Victorian government secondary schools, using data relating to the 1984 school year. It presents results which suggest that while size brings considerable advantages, plateau effects begin to appear at relatively low enrolment levels. The paper comprises five main sections: an outline of the conceptual background to the study; a description of the …

Debate with colleagues about the acceptability of politics of recognition of "alternative" medicine (homeopathy, etc.). Koen Raes and I defend the position that it is not because something is not "scientifically proven" it should not be regulated by government.

Open Doors: Alternative Education, Kimberly J. Sawtelle

Kimberly J. Sawtelle

Dexter Regional High School partners with SAD 46 Adult Education to provide the community's first alternative education program.

Although students currently enrolled in Dexter's alternative program have proven to be bright, well-spoken, and talented with average reading abilities at or above twelfth grade level, the general picture of dropouts is not so rosey. In nearly all cases students are under extreme emotional stress as they struggle against background and social perception to come into their own as individuals. Students qualifying for Alternative Ed. are considered at risk, another in a long line of labels with which each has had to …
