The current trend toward machine-scoring of student work, Ericsson and Haswell argue, has created an emerging issue with implications for higher education across the disciplines, but with particular importance for those in English departments and in administration. The academic community has been silent on the issue—some would say excluded from it—while the commercial entities who develop essay-scoring software have been very active. Machine Scoring of Student Essays is the first volume to seriously consider the educational mechanisms and consequences of this trend, and it offers important discussions from some of the leading scholars in writing assessment. Reading and evaluating student writing is a time-consuming process, yet it is a vital part of both student placement and coursework at post-secondary institutions. In recent years, commercial computer-evaluation programs have been developed to score student essays in both of these contexts. Two-year colleges have been especially drawn to these programs, but four-year institutions are moving to them as well, because of the cost-savings they promise. Unfortunately, to a large extent, the programs have been written, and institutions are installing them, without attention to their instructional validity or adequacy. Since the education software companies are moving so rapidly into what they perceive as a promising new market, a wider discussion of machine-scoring is vital if scholars hope to influence development and/or implementation of the programs being created. What is needed, then, is a critical resource to help teachers and administrators evaluate programs they might be considering, and to more fully envision the instructional consequences of adopting them. And this is the resource that Ericsson and Haswell are providing here.

Despite extensive efforts to control it, malaria is still one of the most devastating infectious diseases worldwide. This book, now in its second edition, provides a broad and up-to-date overview of the rapidly expanding field of malaria immunology and its importance in the control of this disease. The first section deals with the malaria parasite and its interactions with both the vertebrate host and the mosquitoes which transmit the disease. In the second part, the mechanisms of immunity and their regulation by environmental and genetic factors are discussed. Finally, this volume contains several chapters on malaria vaccine development, describing the application of the most recent vaccine technologies as well as ongoing and planned vaccine trials. Authored by well-recognized experts, this volume not only demonstrates the rapid progress being made in the search for vaccines against malaria, but also broadens our understanding of immunity to infection in general. It is therefore highly recommended reading for all scientists and professionals in the fields of immunology, infection and vaccine development.

This superb introduction to the field of organizational psychology and organizational behaviour builds on the foundation of the highly successful first edition to provide up-to-date explanations of all the key topics in a clear, coherent and accessible style. The text is supported by numerous illustrations and examples as well as end-of-chapter summaries and concluding remarks. Topic sections on key research studies, as well as applied aspects such as human resources applications and cross-cultural issues, lead the reader through the complexities of the theory to its practical application. The Psychology of Behaviour at Work covers all major topics in the field, from vocational choice, personality, attitudes, motivation and stress, to cooperation, learning, training, group dynamics, decision making and leadership. Further sections introduce corporate culture and climate, as well as organisational structure, change and development, and a final section outlines predictions not only for the future study of organizational psychology, but of the future of work itself. As with the first edition, The Psychology of Behaviour at Work will prove to be an invaluable resource for psychology students on work and organizational psychology courses, business students on organizational behaviour courses, and human resources managers eager to expand their knowledge of this fascinating field.

Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

Portfolio construction is fundamental to the investment management process. In the 1950s, Harry Markowitz demonstrated the benefits of efficient diversification by formulating a mathematical program for generating the "efficient frontier" to summarize optimal trade-offs between expected return and risk. The Markowitz framework continues to be used as a basis for both practical portfolio construction and emerging research in financial economics. Such concepts as the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (APT), for example, provide the foundation for setting benchmarks, for predicting returns and risk, and for performance measurement. This volume showcases original essays by some of today’s most prominent academics and practitioners in the field on the contemporary application of Markowitz techniques. Covering a wide spectrum of topics, including portfolio selection, data mining tests, and multi-factor risk models, the book presents a comprehensive approach to portfolio construction tools, models, frameworks, and analyses, with both practical and theoretical implications.

The study of Asian historical demography has lagged behind that of its European and American counterparts for some time. This volume serves to narrow the gap by drawing together material from scholars specializing in demography across the spectrum of Asian countries. The collection divides into four parts and contains nineteen chapters covering issues on comparative perspective, fertility, disease and mortality, and marriage and family. The geographic coverage of the chapters is also wide, extending from East Asia to South Asia, with specific emphasis on Japan, China, Taiwan, Indonesia, India, and Sri Lanka. Authors focus on a whole range of social groups, discussing how demographic issues affect and have affected both urban and rural dwellers from the seventeenth to the twentieth century. This volume, which is perhaps the first to bring together a number of in-depth, specialist studies on Asian population history, should prove a useful and engaging tool for both students and academics in the fields of demography, history, and Asian studies.
