The aspects of this text which we believe are novel, at least in degree, include: an effort to motivate different sections with practical examples and an empirical orientation; an effort to intersperse several easily motivated examples throughout the book and to maintain some continuity in these examples; and the extensive use of Monte Carlo simulations to demonstrate particular aspects of the problems and estimators being considered. In terms of material being presented, the unique aspects include the first chapter which attempts to address the use of empirical methods in the social sciences, the seventh chapter which considers models with discrete dependent variables and unobserved variables. Clearly these last two topics in particular are quite advanced--more advanced than material that is currently available on the subject. These last two topics are also currently experiencing rapid development and are not adequately described in most other texts.

Why do people identify with political parties? How stable are those identifications? Stable party systems, with a limited number of parties and mostly stable voter identification with a party, are normally considered significant signals of a steady democracy. In Dynamic Partisanship, Ken Kollman and John E. Jackson study changing patterns of partisanship in the United States, the United Kingdom, Canada, and Australia over the last fifty years in order to disentangle possible reasons for shifting partisanship and party identification. The authors argue that changes in partisanship can be explained by adjustments in voters' attitudes toward issues or parties; the success or failure of policies advocated by parties; or alterations in parties' positions on key issues. They contend that, while all three factors contribute, it is the latter, a party changing positions on a chief concern, that most consistently leads voters to or from a particular party. Their approach provides a deeper knowledge of the critical moving parts in democratic politics.

In the time span of a two-term US presidency, Poland went from an authoritarian one-party state with a faltering centrally planned economy to become a relatively stable multiparty democracy and a market economy with one of the highest GDP growth rates in Europe. A central feature of these economic and political reforms is a high rate of entry of new, domestically owned firms. This book uses detailed economic and political data to examine how these new firms contributed to the Polish transition. The authors test propositions about why some regions have more new firms than others and how the success of these new firms contributed to political constituencies that supported economically liberal parties. The book concludes by contrasting the Polish with the experiences of other transitional countries.

Biology of Apples and Pears is a comprehensive reference book on all aspects of pomology at the organ, tree and orchard level. It provides detailed information on propagation, root and shoot growth, root stock effects, canopy development in relation to orchard design, flowering, pollination, fruit set, fruit growth, fruit quality factors and quality retention in store. It also deals with mineral nutrition, water-relations and irrigation, diseases and pests and biotechnology. The book emphasises the scientific basis of modern tree and orchard management and fruit storage. It describes key cultivar differences and their physiology and genetics and environmental effects and cultivar x environment interactions in tropical and sub-tropical as well as temperate zone conditions. It is written for fruit growers, extension workers, plant breeders, biotechnologists and storage and crop protection specialists as well as for researchers and students of pomology and horticulture.

This comprehensive reference on all aspects of pomology at the organ, tree and orchard level describes the main varieties and rootstocks, and the factors controlling their growth, cropping, fruit quality, storage life, fertilizer and irrigation needs. It emphasizes the principles underlying modern high-density planting and the production of fruits in environments ranging from temperate to tropical. The book will be suitable for fruit farmers and technical advisors as well as scientific researchers and students of pomology and horticulture.
