1/Z expansion, correlation energy, and Shannon entropy of heavy atoms in nonrelativistic limit

It has been known since the work of March and White that the simplest nonrelativistic density functional theory, namely, the statistical method of Thomas, Fermi, and Dirac, sums subseries of the so-called 1/Z expansion to yield, for heavy neutral atoms, the ground-state energy E= − a0Z7/3+ a1Z2−a2Z5/3+⋅⋅⋅. The term of O(Z5/3) is the Dirac–Slater exchange energy Eexc, and it is of considerable interest to know at what order the correlation energy Ecorr enters this expansion. Dimensional scaling considerations by Kais et al. suggested Ecorr∝Z4/3 in the limit of large Z. Here, attention is focused on whether this can be distinguished empirically from a term of the form (aZ ln Z+bZ) for neutral atoms. If the latter term is correct, then a relationship between Ecorr and the Shannon information entropy can be forged analytically for large atomic number Z in nonrelativistic theory. © 1998 John Wiley & Sons, Inc.

Statistical Policy for State and Local Governments

Abstract This report is the product of the Task Force on State and Local Government Statistics formed by the ASA Committee on Government Statistics. The Task Force began its work in March 1985 because of a growing concern among ASA members that state and local governments were undertaking many statistical programs and functions of which the ASA had little knowledge and for which it had little role in supporting, and because of the potential and real impacts of federal policy changes and budget reductions on state statistical programs. The report examines the need for state and local government statistical policy, reviews current practice, summarizes elements of a statistical policy, proposes alternative models for organizing the statistical policy function, and makes recommendations for further action.

Coulomb Liquids

Several books on the statistical mechanics of Coulomb systems already exist, but the work of March and Tosi provides a much more comprehensive survey than has previously been attempted. The book gives an up to date treatment of the properties of liquid metals (including alloys), classical plasmas, molten salts, metal-salt solutions, fast-ion conductors and charged interfaces.

Force between jellium films at small separation in the linearized Thomas-Fermi approximation.

This Brief Report extends and complements the work of March and Paranjape [Phys. Rev. B 30, 3131 (1984)] on the interaction between metallic systems, in various ways. Their analysis for jellium half-spaces, using the linearized Thomas-Fermi approximation, is generalized in the case of film geometries. This is essential in order to account for the intrinsic instability of jellium. Comparison of our results with exact (nonlinear) Thomas-Fermi results reveals successes and failures of the linearized Thomas-Fermi approximation. It is also pointed out that the generalization of the work of March and Paranjape in the case of arbitrary densities is provided by a known exact formula for the force between jellium films at small separation.

Ambiguity as Opportunity and Constraint: Evolution of a Federal Sex Equity Education Program

From the 1960s to the early 1980s educational equity was an important focus for schools, supported by initiatives undertaken by the federal government. This paper takes the position that equity programs developed during that period were suffused with ambiguities, which both aided and hindered the evolution of viable definitions and demonstrations of educational equity. The paper focuses on the National Sex Equity Demonstration Project, a 4-year, joint effort of the University of Miami and the School Board of Broward County funded by the Women’s Educational Equity Act Program. This project was characterized by uncertainty in goals, technologies, roles, relationships, structures, interpretations, and outcomes. The work of March, Cohen, and Olsen on educational systems as organized anarchies is drawn upon extensively to provide a theoretical base for the analysis. The project evaluation conducted by Robert and Bernadine Stake is helpful in illuminating the experience. The paper concludes that the project made a modest but important contribution to the definition of educational equity.

Frames of Meaning: the Rationality in Organisational Cultures

In the light of increasing interest in the study of culture in organisations, this paper advocates the use of 'frames of meaning' as a concept for the study of forms of rationality in such cultures or sub-cultures. Some aspects of the social science treatment of rationality are examined and particular attention is paid to the work of March and Simon on 'bounded rationality'. Then reference is made to phenomenology, anthropology, and the sociology of knowledge in order to develop an adequate definition of the term, 'frame of meaning' Finally, the concept is located in its place in Giddens's theory , of social structuration and related to some recent contributions to organi sation theory.

Melting of Ionic Crystals, Defect Energies and Fast Ion Conduction

Abstract The theory of Kurosawa of melting in ionic crystals is first reviewed. The form of the theory, it is pointed out, receives some measure of support from the Barr-Dawson-Lidiard correlation between melting temperature and Schottky defect enthalpy. Recent work of March et al. on fast ion conduction in the fluorite structure, a phenomenon which is often discussed in terms of sub-lattice melting, is then discussed. The superionic transition temperature is shown in this work to be correlated with the Frenkel defect energy. Some brief comments are made on the effect of fast ion conduction on the melting temperature.

The Nutritional intake of Farmers engaged in Vinylhouse Work

We carried out an investigation of the farmers engaged in vinylhouse work in March 1970, to clarify their nutritional status.Results obtained were as follows:1. Comparing the average nutritional intake of an adult per day with the desirable nutritional standard for Japanese in 1975, only the intake of protein and V. C were over, but the individual difference among the subjects was great.2. The average value of the nitrogen concentration in the urine measured by the corrected urinary concentration method for the estimation of the nutritional status which Takagi proposed indicated that the protein intake of this group was not low.3. Comparing the dietary constituent of an adult per day with the data of the food constitution tables for Japanese in 1975, the intake of meat and poultry, fats and oils, and sugars were evidently insufficient in the males, and the insufficient intake of milk and milk products, fats and oils, fruits and sugars were evident in the females.4. In the pattern of cooking, soup was taken many times in every meal. Most times two kinds of cooked preparations was observed. The menu was simple.It was shown that the dietary life of vinylhouse workers was not significantly different from that of other farmers.
