This paper describes a historic civil engineering bridge site on the Rideau Canal. The history of the site is traced from 1882, when the first bridge was built, to the time of the existing modern structure. Most of the bridges were of the movable type, being either swing or vertical lift structures. The present bridge, which was built in 1980–1981, was designed taking into consideration many of the historic features of past bridges especially the latter bridge, which was built in 1915–1917. Various technical features of the new bridge enhance one's perspective of modem design methods when they are compared with past state-of-the-art methods. The resulting bridge is a functional structure that maintains the heritage of the historic bridges and at the same time blends with the environment.

The article examines the history of development and state-of-the-art of the design theory of structures of filled shells delivered in “Civil Engineering” specialist, MSc, and postgraduate engineering disciplines courses. The analysis of the engineering design methods based on the theory of shells propositions has been performed. Structural numerical model field of application expansion has been proved. The obtained parameters and proposed methods can be used in numerical simulations using finite element method to analyze and design the thin shell structures with soil infill. The propositions reflecting state-of-the-art of the design theory of the structures under consideration have been set; their place in the logic of delivering engineering disciplines taught to civil engineering students has been designated.

For several decades, multi-criteria decision-making (MCDM) methods have been in use to address issues particular to design, organisation and management of constructions. This article reviews the history of MCDM methods since their origins to current times. The academic database Thomson Reuters Web of Science Core Collection was used to overview publications that contain keyword “MCDM” and are included in Web of Science Category “Engineering Civil”. The analysis of publications was made according to their year, state, journals and used MCDM methods.

This volume vividly demonstrates the importance and increasing breadth of quantitative methods in the earth sciences. With contributions from an international cast of leading practitioners, chapters cover a wide range of state-of-the-art methods and applications, including computer modeling and mapping techniques. Many chapters also contain reviews and extensive bibliographies which serve to make this an invaluable introduction to the entire field. In addition to its detailed presentations, the book includes chapters on the history of geomathematics and on R.G.V. Eigen, the "father" of mathematical geology. Written to commemorate the 25th anniversary of the International Association for Mathematical Geology, the book will be sought after by both practitioners and researchers in all branches of geology.

The discovery in mammals that fetal testes are required in order to develop the male phenotype inspired research efforts to elucidate the mechanisms underlying gonadal sex determination and differentiation in vertebrates. A pioneer work in 1966 that demonstrated the influence of incubation temperature on sexual phenotype in some reptilian species triggered great interest in the environment’s role as a modulator of plasticity in sex determination. Several chelonian species have been used as animal models to test hypotheses concerning the mechanisms involved in temperature-dependent sex determination (TSD). This brief review intends to outline the history of scientific efforts that corroborate our current understanding of the state-of-the-art in TSD using chelonian species as a reference.

The History of Education Quarterly has done it again. Despite many scholars' previous attempts to summarize the state of the art in historical studies of literacy, this special issue will now be the best, up-to-date place for a novice to start. It should be required reading for everyone interested in this subfield. The editors have enlisted an impressive roster of prominent scholars in the field, and these authors have provided us with an excellent array of synthetic reviews, methodological and theoretical discussions, and exemplary research papers.

In Recent Years, many discoveries in the history of Islamic mathematics have not been reported outside the specialist literature, even though they raise issues of interest to a larger audience. Thus, our aim in writing this survey is to provide to scholars of Islamic culture an account of the major themes and discoveries of the last decade of research on the history of mathematics in the Islamic world. However, the subject of mathematics comprised much more than what a modern mathematician might think of as belonging to mathematics, so our survey is an overview of what may best be called the “mathematical sciences” in Islam; that is, in addition to such topics as arithmetic, algebra, and geometry we will also be interested in mechanics, optics, and mathematical instruments.

Abstract Over two decades ago, Korpi and Palme (1998) published one of the most influential papers in the history of social policy discipline, in which they put forward a “paradox of redistribution”: the more countries target welfare resources exclusively at the poor, the less redistribution is actually achieved and the less income inequality and poverty are reduced. The current paper provides a state-of-the-art review of empirical research into that paradox. More specifically, we break down the paradox into seven core assumptions, which together form a causal chain running from institutional design to redistributive outcomes. For each causal assumption, we offer a comprehensive and critical review of the relevant empirical literature, also including a broader range of studies that do not aim to address Korpi and Palme’s paradox per se, but are nevertheless informative about it.
