This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

Under what conditions are expressions of a language the same; when are they different? Indices and Identity focuses on this question in the context of the theory of anaphora and on the role of indices in characterizing syntactic and semantic identity of expressions. Fiengo and May develop two main themes within the theory of anaphora. The first pertains to the meaning of coindexing and non-coindexing--the correspondence between indexical relations among expressions and the valuation relation that holds among them--while the second is the development of Dependency Theory, the theory of the relations of occurrences of indices. The novelty of Fiengo and May's approach lies with their characterization of indexical dependencies and the conditions under which structures manifest the same or different dependency. In particular, Indices and Identity emphasizes issues raised by strict and sloppy identity in ellipsis, exploring what Fiengo and May call the eliminative puzzles of ellipsis. The significance of these puzzles is that they show the shortcomings of current theories of anaphora in ellipsis, while illustrating an application of Dependency Theory to complex cases of strict and sloppy identity. Elliptical contexts in turn lead to consideration of the embedding of the formal syntactic notions of identity arising from indices and dependencies within more general notions of structural identity. This relates to a consideration of the foundations of reconstruction, which, the authors argue, is syntactic identity up to indexical identity and vehicle change--variation in the syntactic form of expression of arguments.The book concludes with a discussion of the relation of reconstruction, logical representation in grammar, and the application of grammatical constraints. The discussion focuses on antecedent contained deletion, and stands independently as a comprehensive study of this construction. Linguistic Inquiry Monograph No. 24

The use of numbers to condense complex systems into easily digested 'bites' of information is very much in fashion. At one level they are intended to enhance transparency, accountability and local democracy, while at another they provide a means of enhancing performance. However, all indicators suffer from the same basic problem that, ironically, is also their biggest advantage - condensing something highly complex into a few simple numbers. Love them or hate them, there is no denying that people use indicators to make decisions. Indices and Indicators explores the use of indicators within the field of human development. Part I provides a brief outline of the contested meaning of 'development' and how indices and indicators have been used as means of testing the realization of these development visions in practice in a range of institutional contexts. Part II discusses the limitations of such indices and indicators and illustrates how they are dependent upon the vision of development adopted. The book also suggests how indices and indicators can best be employed and presented. Given our overwhelming reliance on indices and indicators for measuring progress, directing policy and allocating resources, this book is essential core reading for academics, undergraduate and post-graduate students in social science, economics, geography and development studies as well as development practitioners, policy-makers and donor and international funding agencies.

Indices, index funds and ETFs are grossly inaccurate and inefficient and affect more than €120 trillion worth of securities, debts and commodities worldwide. This book analyzes the mathematical/statistical biases, misrepresentations, recursiveness, nonlinear risk and homomorphisms inherent in equity, debt, risk-adjusted, options-based, CDS and commodity indices – and by extension, associated index funds and ETFs. The book characterizes the “Popular-Index Ecosystems,” a phenomenon that provides artificial price-support for financial instruments, and can cause systemic risk, financial instability, earnings management and inflation. The book explains why indices and strategic alliances invalidate Third-Generation Prospect Theory (PT3), related approaches and most theories of Intertemporal Asset Pricing. This book introduces three new decision models, and some new types of indices that are more efficient than existing stock/bond indices. The book explains why the Mean-Variance framework, the Put-Call Parity theorem, ICAPM/CAPM, the Sharpe Ratio, Treynor Ratio, Jensen’s Alpha, the Information Ratio, and DEA-Based Performance Measures are wrong. Leveraged/inverse ETFs and synthetic ETFs are misleading and inaccurate and non-legislative methods that reduce index arbitrage and ETF arbitrage are introduced.

In ordinary discourse we appear to ta1k about many things that have seemed mysterious to philosophers. We say that there has been a hitch in our arrangements or that the solution to the problem required us to examine all the probable outcomes of our action. So it would seem that we speak as if in addition to eloeks, mountains, queens and grains of sand there are hitches, arrangements, solutions, probiems, and probable outcomes. It is not immediately obvious when we must take such ta1k as really assuming that there are such to develop tests for things, and one of the tasks in this book is discerning what has eome to be called ontological commitment, in naturallanguage. Among the entities that natural language appears to make reference to are those connected with temporal and modal discourse, times, possibilities, and so on. Such entities play a crueial role in the kind of semantieal theories that I and others have defended over many years. These theories are based on the idea that an essential part of the meaning of a sentence is constituted by the conditions under whieh that sentenee is true. To know what a sentence says is to know what the world would have to be !ike for that sentence to be true.
