AS CONCORDE HAS GROWN considerably in size and capacity since the prototype, the air conditioning system has correspondingly been revised and together with refinements to the air bleed and temperature control aspects of the system now represents as nearly as possible the final production configuration.

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

Contact problems are among the most difficult ones in mechanics. Due to its practical importance, the problem has been receiving extensive research work over the years. The finite element method has been widely used to solve contact problems with various grades of complexity. Great progress has been made on both theoretical studies and engineering applications. This paper reviews some of the main developments in contact theories and finite element solution techniques for static contact problems. Classical and variational formulations of the problem are first given and then finite element solution techniques are reviewed. Available constraint methods, friction laws and contact searching algorithms are also briefly described. At the end of the paper, a bibliography is included, listing about seven hundred papers which are related to static contact problems and have been published in various journals and conference proceedings from 1976.

The purpose of this paper is to explore and quantify the impact of geographically defined school zones on house prices in New Zealand.

This paper develops a series of hedonic pricing models to analyse 10,000 house sales transactions over a 21‐year period within a compact group of inner Auckland suburbs, which represents the epicentre of the school zoning debate in New Zealand. The study diverts from past research, which mainly focuses on school quality measures such as standardised test scores, and instead analyses the comprehensive price impacts of access to popular state schools. Its unique approach employs a geographic information system to divide the study area into effective school zones and then further subdivide into suburbs, thus offering a vital indicator of internal validity.

The study's findings indicate that the influence of school zoning on house prices is not uniform and the variation in price effects is largely a function of the uncertainty of future zone boundary definitions. Although some “in‐zone” suburbs have enjoyed accelerated house price growth following the reintroduction of zoning in 2000, peripheral suburbs’ price premiums have diminished.

In contrast to standard hedonic studies on school quality, this paper offers an innovative approach that integrates geography to solve what is essentially a spatial economic problem.

Elsewhere in this issue we review the First (Interim) Report of the Joint Survey of Pesticide Residues in Foodstuffs, published by the Association of Public Analysts (Editor: Mr. D. G. Forbes, B.Sc., F.R.I.C.). The Scheme, planned with meticulous care and executed with the best spirit of co‐operation, sets a pattern for this type of investigation; there are other problems which could be studied in the same manner. Such a response from the bodies representing the major local authorities of the country and their food and drugs administrations—inspectors, food sampling officers, public analysts—is evidence of the concern felt over this particular form of contamination of food. It constitutes a public health problem of world‐wide dimensions. The annual reports of public analysts show that many are examining foods outside the Survey lists now that gas/liquid chromatography, spectroscopy and other highly refined methods of analysis are available to them.

The purpose of this paper is to study the wave propagation in thermoelastic diffusive medium.

The present paper deals with the numerical study of wave propagation in coupled thermoelastic diffusive medium by using DQ method together with fourth‐order Runge‐Kutta method.

The paper finds solutions of displacements, temperature change and concentration.

The paper can be sued to solve non‐linear partial differential equations.

The solutions of displacements, temperature change and concentration are illustrated graphically. Numerical examples show that the method yields very good results.

MY reaction to being appointed Director of Library Services would be one of frank amazement, rather as if I had been a commercial traveller in a rather dubious line of trade, such as ladies' underwear, who had suddenly been offered a bishopric. The recovery from this amazement would take about ten seconds flat and I would doubtless find myself in the thick of finding an office, a desk, a rubber plant and a regulation‐size piece of carpet appropriate to my grade. My first real task would be to bring some order to the seven sections of the D.E.S. now dealing with library matters and to initiate among librarians generally some radical thinking on the problems that face us all.

The current study aims to explain the influence of technological interactivity and media sociability on sport consumer value co-creation behavior via collective efficacy and collective intelligence.

Subjects were individuals who have a mobile smart device and experience of accessing sport-related community websites (n = 513). A face-to-face self-administered survey was employed based on the convenience sampling method. A structural equation modeling test was conducted to examine the relationships between the variables.

Technological interactivity and media sociability based on mobile smart devices improve sport consumers' collective efficacy, and media sociability positively affects collective intelligence. Also, perceived collective efficacy and collective intelligence in virtual communities induce consumers to engage in the value co-creation process more actively (i.e. consumer participation behavior and citizenship behavior). One of the key findings includes the significant role of media sociability in the process of value co-creation between consumers and sport organizations. Media sociability is more likely to contribute to improving sport consumers' collective efficacy and the development of intelligence than the properties of technological interactivity.

Research findings contribute to extending the body of knowledge in interactivity studies related to sport consumers' value co-creation behaviors in the virtual environment context.

Within-prison drug injection (WPDI) is a particularly high HIV risk behavior, yet has not been examined in Central Asia. A unique opportunity in Kyrgyzstan where both methadone maintenance treatment (MMT) and needle-syringe programs (NSP) exist allowed further inquiry into this high risk environment. The paper aims to discuss these issues.

A randomly selected, nationally representative sample of prisoners within six months of release in Kyrgyzstan completed biobehavioral surveys. Inquiry about drug injection focused on three time periods (lifetime, 30 days before incarceration and during incarceration). The authors performed bivariate and multivariable generalized linear modeling with quasi-binomial distribution and logit link to determine the independent correlates of current WPDI.

Of 368 prisoners (13 percent women), 109 (35 percent) had ever injected drugs, with most (86 percent) reporting WPDI. Among those reporting WPDI, 34.8 percent had initiated drug injection within prison. Despite nearly all (95 percent) drug injectors having initiated MMT previously, current MMT use was low with coverage only reaching 11 percent of drug injectors. Two factors were independently correlated with WPDI: drug injection in the 30 days before the current incarceration (AOR=12.6; 95%CI=3.3-48.9) and having hepatitis C infection (AOR: 10.1; 95%CI=2.5-41.0).

This study is the only examination of WPDI from a nationally representative survey of prisoners where both MMT and NSP are available in prisons and in a region where HIV incidence and mortality are increasing. WPDI levels were extraordinarily high in the presence of low uptake of prison-based MMT. Interventions that effectively scale-up MMT are urgently required as well as an investigation of the environmental factors that contribute to the interplay between MMT and WPDI.

The purpose of this paper is to develop two meshfree algorithms based on multiquadric radial basis functions (RBFs) and differential quadrature (DQ) technique for numerical simulation and to capture the shocks behavior of Burgers’ type problems.

The algorithms convert the problems into a system of ordinary differential equations which are solved by the Runge–Kutta method.

Two meshfree algorithms are developed and their stability is discussed. Numerical experiment is done to check the efficiency of the algorithms, and some shock behaviors of the problems are presented. The proposed algorithms are found to be accurate, simple and fast.

The present algorithms LRBF-DQM and GRBF-DQM are based on radial basis functions, which are new for Burgers’ type problems. It is concluded from the numerical experiments that LRBF-DQM is better than GRBF-DQM. The algorithms give better results than available literature.
