Robust Correlation

Theory and Applications

This bookpresents material on both the analysis of the classical concepts of correlation and on the development of their robust versions, as well as discussing the related concepts of correlation matrices, partial correlation, canonical correlation, rank correlations, with the corresponding robust and non-robust estimation procedures. Every chapter contains a set of examples with simulated and real-life data. Key features: Makes modern and robust correlation methods readily available and understandable to practitioners, specialists, and consultants working in various fields. Focuses on implementation of methodology and application of robust correlation with R. Introduces the main approaches in robust statistics, such as Huber’s minimax approach and Hampel’s approach based on influence functions. Explores various robust estimates of the correlation coefficient including the minimax variance and bias estimates as well as the most B- and V-robust estimates. Contains applications of robust correlation methods to exploratory data analysis, multivariate statistics, statistics of time series, and to real-life data. Includes an accompanying website featuring computer code and datasets Features exercises and examples throughout the text using both small and large data sets. Theoretical and applied statisticians, specialists in multivariate statistics, robust statistics, robust time series analysis, data analysis and signal processing will benefit from this book. Practitioners who use correlation based methods in their work as well as postgraduate students in statistics will also find this book useful.

However, in many cases it is almost impossible to ensure an upper bound on the

Elements of Physical Hydrology

Among the many diverse aspects of environmental science, none is more critical to the future of society and nature than water. Understanding the role of water on Earth and making good decisions regarding water conservation and hydrological hazards depends on learning the fundamentals of physical hydrology. This textbook, now in an expanded second edition, provides the clearest opportunity for students to absorb those fundamentals. Written at an introductory level, Elements of Physical Hydrology covers virtually every aspect of this subject, including: • The hydrological cycle• Water budgets at catchment to global scales • Spatial and temporal aspects of precipitation• Evapotranspiration• Fluid dynamics and the Bernoulli equation• Laminar and turbulent flows• Open channel flow • Flood movement through reservoirs and channels • Flood frequency analysis• Groundwater flow• Aquifer characterization• Land subsidence• Soil moisture dynamics• Flow in the unsaturated zone• Hydrologic controls on vegetation • Biotic controls on hydrological processes• Runoff generation from surface and subsurface sources• Catchment models• The water-food-energy nexus• The globalization of water• Impacts of changing climate Layering one topic upon the next, Elements of Physical Hydrology succeeds in moving from simple, easy-to-grasp explanations through equations and models in a manner that will leave students new to the topic eager to apply their knowledge. Professionals in related disciplines will also find this book ideal for self-study. Thoughtfully illustrated, carefully written, and covering a broad spectrum of topics, this classic text clarifies a subject that is often misunderstood and oversimplified.

Water also has the greatest specific heat capacity and latent heat of vaporization
known among liquids, and has a higher thermal conductivity than any other liquid
except mercury. It also has a high heat of fusion. One consequence of these
properties is that water at the Earth's surface tends to moderate effects of hot or
cold air temperatures. Water Density and Viscosity Liquid water contracts as it
cools, reaching a maximum density (ρ) of 1000kg m−3 at 3.98°C (Figure A2.1;
Table A2.1) ...

Procrastination and Task Avoidance

Theory, Research, and Treatment

Procrastination is a fascinating, highly complex human phenomenon for which the time has come for systematic theoretical and therapeutic effort. The present volume reflects this effort. It was a labor of love to read this scholarly, timely book-the first of its kind on the topic. It was especially encouraging to find that its authors are remarkably free of the phenomenon they have been investigating. One might have expected the opposite. It has often been argued that people select topics that trouble them and come to understand their problems better by studying or treating them in others. This does not appear to be true of the procrastination researchers represented in this book. I base this conclusion on two simple observations. First, the work is replete with recent refer ences and the book itself has reached the reader scarcely a year following its completion. Second, when one considers the remarkable pace of pro grammatic research by these contributors during the past decade, it is clear that they are at the healthy end of the procrastination continuum. The fascinating history of the term procrastination is well documented in this book. The term continues to conjure up contrasting, eloquent images-especially for poets. When Edward Young wrote in 1742, "Pro crastination is the Thief of Time," he was condemning the waste of the most precious of human commodities.

The present volume reflects this effort. It was a labor of love to read this scholarly, timely book-the first of its kind on the topic.

A EXCELENCIA EM SERVIÇOS

Serviços de qualidade superior tem se revelado uma estratégia competitiva vencedora e o maior desafio para as empresas, mas como avaliar a qualidade dos serviços prestados e incrementá-los? A metodologia SERVQUAL, desenvolvida pelos autores desta obra, pioneiros nas pesquisas sobre o tema, é a ferramenta que permite mensurar essas informações. Ela mede qualitativa e quantitativamente o grau de satisfação dos clientes, considerando as cinco dimensões da qualidade dos serviços - tangibilidade, confiabilidade, responsividade, segurança e empatia. Permite, ainda, a criação de serviços diferenciados e aumento da produtividade, fidelizando os clientes e gerando publicidade positiva, o que irá render a sustentação do sucesso em longo prazo. 'A excelência em serviços - Como superar as expectativas e garantir a satisfação completa de seus clientes' descreve em detalhes, mas, ao mesmo tempo, de forma bastante simples e didática, o processo de desenvolvimento da consagrada escala SERVQUAL. Conheça todo o embasamento e desenvolvimento deste modelo que se tornou referência absoluta para todos os estudos posteriores na área de Marketing de serviços. Totalmente adaptada e atualizada, esta obra oferece um modelo para a ação e um caminho para o sucesso.
