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.

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.

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.

This study may be the most sophisticated statistical study of legislative voting now in print. The author asks why legislators, especially U.S. senators, vote as they do. Are they influenced by their constituencies, party, committee leaders, the President? By taking a relatively short time span, the years 1961 to 1963, the author is able to give us answers far beyond any we have had before, and some rather surprising ones at that. Constituencies played a different, but more important role in senators' voting than earlier studies have shown. Senators appeared to be responding both to the opinion held by their constituents on different issues and to the intensity with which these opinions were held. On the interrelation of constituencies and party, Mr. Jackson finds that Republicans and southern Democrats were particularly influenced by their voters. The clearest cases of leadership influence were among the non-southern members of the Democratic Party. Western Republicans, on the other hand, rejected the leadership of party members for that of committee leaders. Finally, on Presidential leadership, Mr. Jackson shows that John F. Kennedy influenced senators only during the first two years of his administration. All of these findings challenge conventional wisdom and are bound to influence future work in legislative behavior.
