Abstract
Purpose
The purpose of this paper is to apply the meshless method of fundamental solutions (MFS) to the two‐dimensional time‐dependent heat equation in order to locate an unknown internal inclusion.
Design/methodology/approach
The problem is formulated as an inverse geometric problem, using non‐invasive Dirichlet and Neumann exterior boundary data to find the internal boundary using a non‐linear least‐squares minimisation approach. The solver will be tested when locating a variety of internal formations.
Findings
The method implemented was proven to be both stable and reasonably accurate when data were contaminated with random noise.
Research limitations/implications
Owing to limited computational time, spatial resolution of internal boundaries may be lower than some similar case investigations.
Practical implications
This research will have practical implications to the modelling and monitoring of crystalline deposit formations within the nuclear industry, allowing development of future designs.
Originality/value
Similar work has been completed in regards to the steady state heat equation, however to the best of the authors' knowledge no previous work has been completed on a time‐dependent inverse inclusion problem relating to the heat equation, using the MFS. Preliminary results presented here will have value for possible future design and monitoring within the nuclear industry

Abstract
It is appropriate to begin with some observations on the development of Public Administration, for the development of Comparative Public Administration and its present problems are most clearly viewed in historical perspective: The logical problems are related to a chronological development.

Abstract
The decade of the 1980s was unique for the sheer quantity of education reform reports and legislation. Virtually every state enacted education reform legislation, including reforms of teacher education, licensing, and comprehension. According to Darling‐Hammond and Berry, over 1,000 pieces of legislation related to teachers have been drafted since 1980, and “a substantial fraction have been implemented.” As I discussed in my 1989 RSR article, “Five Years after A Nation at Risk: An Annotated Bibliography,” two waves of 1980s reform reports were identified in the enormous body of primary and secondary literature dealing with education reform. The reform publications of the early 1980s stressed improvements in curricular standards, student performance outcomes, and changes to the education programs, such as salary increases, teacher testing, and stricter certification requirements. The second‐wave reform publications emphasized more complex issues centered around the concepts of restructuring the schools and teacher education programs, as well as empowering teachers to become more involved in curriculum and governance issues.

Abstract
The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

Abstract
Why do we need an article which reviews and compares almanacs? Can we learn anything new by re‐examining these heavily used, everyday tools? The authors — two experienced reference librarians, frequent users of almanacs — were surprised by what they learned. Not only did their opinions of individual almanacs change, but also they were pleased to discover information on topics they never thought were covered.

Abstract
OUR readers do not need the reminder that 1952 is the 75th year of Library Association history. Some opportunity may be found at the Bournemouth Conference to celebrate this fact, in however modest a manner. The American Library Association, older by a year, celebrated its anniversary at Philadelphia last October, on which occasion Mr. F. G. B. Hutchings represented this country and spoke at a luncheon meeting to three hundred of the guests with acceptance. That celebration, however, appears to us to have been most significant for the comment on the Carnegie library gifts which was made by Mr. Ralph Munn, librarian of Pittsburgh Carnegie Library, in some ways the most spectacular one founded by the great Scot. Munn said:—

Abstract
The Coase theorem is associated with Stigler because Stigler coined the term. The object of this paper is to show that Stigler’s Coase theorem is Stiglerian for deeper – namely, methodological – reasons. We argue that, convinced as he was by the importance of Coase’s message, Stigler also believed that this message – such as presented in “The Federal Communications Commission” (1959) or “The Problem of Social Cost” (1962) – was not scientific. Hence, he had to transform it into a theorem to give it a scientific dimension. This is what we try to show by presenting Stigler’s methodology and by confronting it to the methodology used in Coase’s articles.

Abstract
Blues music is in the midst of its second revival in popularity in roughly thirty years. The year 1960 can be identified, with some qualification, as a reference point for the first rise in international awareness and appreciation of the blues. This first period of wide‐spread white interest in the blues continued until the early seventies, while the current revival began in the middle 1980s. During both periods a sizeable literature on the blues has appeared. This article provides a thumbnail sketch of the popularity of the blues, followed by a description of scholarly and critical literature devoted to the music. Documentary and instructional materials in audio and video formats are also discussed. Recommendations are made for library collections and a list of selected sources is included at the end of the article.
